An attribute is a property of an element used to provide access to additional data required for that specific element to process the output. Each element in HTML consists of several attributes that act as a property for that element, followed by the appropriate value. An attribute with a custom value is required when you want to alter the behavior of an element; hence, in React, you can use an in-built attribute of a component or create a custom attribute for the child component. In this guide, you will learn how to pass static and dynamic values to the attribute and create a custom attribute for the child components. Any attribute associated with the UI element needs the value to make it work. Thhe value can be anything, that is, static or dynamic. If you have a fixed value for an element, then it calls static values that are stored in variables, and once you need to use that value, it consumes directly. For example, say you have the <img> element in your React component, and the URL is stored in a state variable, as shown below. 1constructor() { 2 super(); 3 this.state = { 4 imageUrl: "your_image_url", 5 }; 6} You need to place one state variable inside the local state of the component imageUrl3, where you can put an appropriate path or URL of the image. The state variable can be consumed directly with the element, as shown below. 1render() { 2 console.log(this.props) 3 return ( 4 <div> 5 <img src={this.state.imageUrl} /> 6 </div> 7 ); 8} As you can see, this.state.imageUrl is accessed from the local state; hence, it’s called dynamic value to the src attribute and the imageUrl as a static value. In the same way, it can also be applied to different elements, and a few examples are shown below. 1render() { 2 console.log(this.props) 3 return ( 4 <div> 5 <a href={this.state.linkUrl} 6 Hit me to reach Google 7 </a> 8 <input type="text" value={this.state.inputValue} /> 9 </div> 10 ); 11} Along with the <a> attribute, the static value used is this.state.linkUrl, and with the <input> control, this.state.inputValue is used as a static value to the attribute. So far in this guide, you have learned how to pass static values to an attribute. But that may require you to use frequently changed values along with the attribute. For example, you may have one text input, and its element’s value updates as you change its value. The example below demonstrates this. Create one state variable with a default value. 1constructor() { 2 super(); 3 this.state = { 4 fullName: "test" 5 }; 6} Now create the <input> element along with the required attributes. 1render() { 2 return ( 3 <div> 4 Enter full name :{" "} 5 <input 6 type="text" 7 value={this.state.fullName} 8 onChange={this.onValueChange} 9 /> 10 </div> 11 ); 12} In the above example, the game-changer props are onChange(), used to update the existing value with the updated value. 1onValueChange = event => { 2 this.setState({ fullName: event.target.value }); 3}; So, once you update the existing value in input control, it will be updated into the state, and the same value will appear in input control using the props, as shown below. 1value={this.state.fullName} By consuming and updating the different state values, you can provide dynamic values to the element’s attribute. Events are handy when user interaction is required in the existing page; thus, values can also be passed to an event attribute as with the in-built attributes of the elements, such as src, href, value, height, width, and so on. You can define the values anywhere, such as the local state in the components, to pass the values to the event attribute. See below. 1constructor() { 2 super(); 3 this.state = { 4 student: { 5 name: "heyfoo", 6 age: "18" 7 } 8 }; 9} Inside the state object of the component, student is a custom object created along with the key-value pair. The next step is to implement an event attribute, such as onClick(). 1render() { 2 return ( 3 <div> 4 <span onClick={() => this.setObjectValue(this.state.student)}> 5 Send object 6 </span> 7 </div> 8 ); 9} Inside the <div>, there is one element created, <span>, along with the event attribute, called onClick, which triggers the event when the user clicks on the span element. Once the user clicks on the element, you can pass any custom values as a function argument. 1onClick={() => this.setObjectValue(this.state.student)} this.setObjectValue is a custom function that accepts one argument, and the static argument given is this.state.student. To access the object from the event function, see below. 1setObjectValue(obj) { 2 console.log(obj); 3} You can pass any static or dynamic values along with the event function, just like in the above example. Attributes play an essential role when using HTML elements with static or dynamic values to achieve interactive results. I hope this guide helps you to implement various ways to provide value to an attribute.	https://www.pluralsight.com/guides/how-to-pass-values-inside-attributes	CC-MAIN-2022-40	refinedweb	844	64

: As you can see, there are different types of nodes:: 1 /* Helper function to generate a DOM Element for the given DOM document 2 and append it to the children of the given node. / 3 QDomElement addElement( QDomDocument &doc, QDomNode &node, 4 const QString &tag, 5 const QString &value = QString::null ) 6 { 7 QDomElement el = doc.createElement( tag ); 8 node.appendChild( el ); 9 if ( !value.isNull() ) { 10 QDomText txt = doc.createTextNode( value ); 11 el.appendChild( txt ); 12 } 13 return el; 14 } 15 16 17 QString holidaySetToXML( const HolidaySet &hs ) 18 { 19 QDomDocument doc; 20 QDomProcessingInstruction instr = doc.createProcessingInstruction( 21 "xml", "version='1.0' encoding='UTF-8'"); 22 doc.appendChild(instr); 23 24 // generate holidayset tag as root, add country attribute if needed 25 QDomElement holidaySetElement = addElement( doc, doc, "holidayset" ); 26 if ( !hs.mCountry.isEmpty() ) 27 holidaySetElement.setAttribute( "country", hs.mCountry ); 28 29 // Add the <name> and <comment> elements to the holidayset 30 if ( !hs.mName.isEmpty() ) 31 addElement( doc, holidaySetElement, "name", hs.mName ); 32 33 // Add each holiday as a <holiday>..</holiday> element 34 QList<Holiday>::iterator i; 35 for ( i = hs.mHolidays.begin(); i != hs.mHolidays.end(); ++i) { 36 QDomElement h = addElement( doc, holidaySetElement, "holiday" ); 37 addElement( doc, h, "name", (i).mName ); 38 addElement( doc, h, "date", (i).mDate.toString( Qt::ISODate ) ); 39 } 40 41 return doc.toString(); 42 } One thing to notice is that all DOM nodes are passed by value (since some programming languages do not define pointers, the DOM API cannot use any pointer-based functionality!). The.. In this chapter we will now look at how we can parse the XML holiday set into the HolidaySet structure using the DOM method. The parsing using a SAX parser will be treated in a later chapter. The usual way to parse an XML document into a DOM tree is to use the method QDomDocument::setContent. If this method is successful, the QDomDocument object contains the DOM tree in the usual DOM structure. If an error occurs, the error message and the exact position of the error is stored into the parameters of the call: 1 QFile f( argv[1] ); 2 QDomDocument doc; 3 QString errorMsg; 4 int errorLine, errorColumn; 5 if ( doc.setContent( &f, &errorMsg, &errorLine, &errorColumn ) ) { 6 result = parseXMLwithDOM( doc ); 7 } The resulting QDomDocument now contains the whole DOM tree, similar to the one that we created in the previous section. The DOM tree represents the hierarchical structure as shown in the image above. To obtain an element with a given tag name, one can use the QDomNode::namedItem( "tagname" ) method of the parent node object, which returns a QDomNode (this class is the base type to describe any of the DOM nodes). As we are interested in the element, we have to convert it to a DOM element by the toElement() method. You might find this to be quite awkward to use, in particular since C++ usually offers better ways to work with derived classes. However, the DOM API was designed to work with various different languages, so typical C++-isms cannot be part of the DOM API. To extract the holiday data from the DOM tree, we write the function parseXMLwithDOM: HolidaySet parseXMLwithDOM( QDomDocument &domTree ) { HolidaySet hs( QString::null ); We first obtain the DOM element that represents the <holidayset>...</holidayset> element using the namedItem and toElement methods. If no child node named "holidayset" exists or it is not an element (e.g. because it is a processing instruction or an attribute), a null element is returned: QDomElement set = domTree.namedItem("holidayset").toElement(); if ( set.isNull() ) { qWarning() << "No <holidayset> element found at the top-level " << "of the XML file!"; return hs; // no holiday set found } This element possibly has an attribute named "country". This can be checked using the QDomNode::hasAttribute method and the attribute can be obtained using the QDomNode::attribute method: if ( set.hasAttribute("country") ) { hs.mCountry = set.attribute("country"); } We can also have a <name>...</name> child element, which can be obtained similar to the holidayset element. We retrieve the text of the element between the enclosing tags by a call to QDomElement::text(): // Search for a given element (only the first matching is returned): QDomElement name = set.namedItem("name").toElement(); if ( !name.isNull() ) { // We have a <name>..</name> element in the set hs.mName = name.text(); } The namedItem method will always return the first child that matches the given name. While this might be fine for the <name> child element, we cannot use this for the <holiday>...</holiday> elements, which will appear more than once. For this reason, there are iterator-like calls firstChild() and and nextSibling() to walk through all child nodes and firstChildElement("tagname") and nextSiblingElement("tagname") to walk only through all child elements with the given tag name. If no further child can be found, a null node is returned: // Way 1: Loop through all child nodes with a given tag name. QDomElement e = set.firstChildElement( "holiday" ); for ( ; !e.isNull(); e = e.nextSiblingElement( "holiday" ) ) { Holiday h; // e is the <holiday>...</holiday> element.... // Load the contents of e into h hs.mHolidays.append( h ); } // Way 2: Loop through all child nodes and check if it is an element // with one of the wanted tagnames QDomNode nd = set.firstChild(); for ( ; !nd.isNull(); nd = nd.nextSibling() ) { if ( nd.isElement() && nd.toElement().tagName() == "holiday" ) { QDomElement e = nd.toElement(); Holiday h; // Same code as above... // e is the <holiday>...</holiday> element.... // Load the contents of e into h hs.mHolidays.append( h ); } } The first method is of course the better and simpler choice in our example. However, if the <holidayset> element can have various different child elements, it's often easier and faster to loop through all children only once and condition the code on the name of the tag, which is done in the second example. If one looks at the API documentation of the QDomElement class, one will also find a method elementsByTagName, which returns a QDomNodeList that can be traversed using iterators. The problem with this method is that it is recursive, i.e. it will return all child elements with the given name at any level (in a well-defined canonical order). We, however, only want the immediate children of the <holidayset> element, but not sub- or subsubchildren. Now that we have the QDomElement of the <holiday>...</holiday> element, we can easily load its contents into the Holiday structure, using only methods that we have already seen: Holiday h; QDomElement v = e.namedItem("name").toElement(); if ( !v.isNull() ) h.mName = v.text(); v = e.namedItem("date").toElement(); if ( !v.isNull() ) { h.mDate = QDate::fromString( v.text(), Qt::ISODate ); } hs.mHolidays.append( h ); This concludes our method for loading the holiday set data from the DOM tree representation into the HolidaySet data structure. The whole parseXMLwithDOM function thus reads: 1 HolidaySet parseXMLwithDOM( QDomDocument &domTree ) 2 { 3 HolidaySet hs( QString::null ); 4 5 QDomElement set = domTree.namedItem("holidayset").toElement(); 6 if ( set.isNull() ) { 7 qWarning() << "No <holidayset> element found at the top-level " 8 << "of the XML file!"; 9 return hs; // no holiday set found 10 } 11 12 if ( set.hasAttribute("country") ) { 13 hs.mCountry = set.attribute("country"); 14 } 15 16 // Way 1: Explicitly search for a given element: 17 QDomElement name = set.namedItem("name").toElement(); 18 if ( !name.isNull() ) { // We have a <name>..</name> element in the set 19 hs.mName = name.text(); 20 } 21 22 // Way 2: Loop through all child nodes with a given tag name. 23 QDomElement n = set.firstChildElement( "holiday" ); 24 for ( ; !n.isNull(); n = n.nextSiblingElement( "holiday" ) ) { 25 Holiday h; 26 QDomElement e = n.toElement(); 27 QDomElement v = e.namedItem("name").toElement(); 28 if ( !v.isNull() ) h.mName = v.text(); 29 v = e.namedItem("date").toElement(); 30 if ( !v.isNull() ) { 31 h.mDate = QDate::fromString( v.text(), Qt::ISODate ); 32 } 33 hs.mHolidays.append( h ); 34 } 35 36 // Way 3: Loop through all child nodes and check if it is an element 37 // with one of the wanted tagnames 38 QDomNode nd = set.firstChild(); 39 for ( ; !nd.isNull(); nd = nd.nextSibling() ) { 40 if ( nd.isElement() && nd.toElement().tagName() == "holiday" ) { 41 QDomElement n = nd.toElement(); 42 // Same code as above... 43 } 44 } 45 46 return hs; 47 } If you are working with complex XML files, sooner or later you will realize that you are using tags and attributes that can be categorized according to their meaning. Even worse, you might encounter tags with the same named used for completely different things. For example, if you are managing a large document describing books and their authors, you might use a <title> element to denote the title of the book, as well as the job title of the author. So, clearly there should be a way to distinguish these two elements with the same name, but different usages. This can be done via XML namespaces, using prefixes to the elements. A namespace is a unique URI (not necessarily a URL!), e.g. "" or "urn:kde:developer:tutorials:QtDom:holidays". Rathern than using these long and awkward URIs with each element, you have to define a prefix for each of the namespaces. This is done via an xmlns:yourprefix="your:namespace:uri" attribute to the element or any of its parents. This defines the "yourprefix" prefix as a shortcut to the full namespace URI "your:namespace:uri". Usually, the namespace declaration is added to the root element of hte XML file. To use an element from this namespace, you can simply prepend the prefix to the tag name: <yourprefix:tag>. This tag name together with the prefix is called the "qualified name" (or in short qName) or the element. The various parts of the element (which you will find in the Qt DOM API, too), are: (As a side note: If an element does not use any namespaces and thus also no prefix, e.g. <tag>, all these parts of the qName are empty and only the "tag name" is set to "tag".) Using this new knowledge about namespaces, of course, we want to generate and process holiday files with proper namespaces. For example, we could define all the tags to be in the namespace "urn:kde:developer:tutorials:QtDom:holidays", indicated by the prefix "h". A typical XML file would then look like: <> So far, we created elements (without namespaces) using the QDomDocument:createElement(...) method. Qt, or rather DOM, offers a simply way to generate elements with a namespace attached: QDomDocument::createElementNS( const QString &nsURI, const QString &qName ) doc.createElement( "holiday" ); with doc.createElementNS( "urn:kde:developer:tutorials:QtDom:holidays", "h:holiday" ); Again, we can write our own helper method "addElementNS": /(); } } Unfortunately, the correct way laid out above does not produce valid XML with Qt versions at least up to 4.2.0: <(); } The output now becomes the correct XML code: <> Of course, noone forces you to use Qt's DOM classes to generate the XML code.

Extras/SteeringCommittee/Meeting-20060511 From FedoraProject Summary Present from FESco -- scop, warren, mschwendt, skvidal, jpo, skvidal - Weekly sponsorship nomination - we need more reviewers. - "Education" is key to getting more reviewers. - tibbs and warren will improve the docs in the wiki - Incompatible package upgrade policy - that's a old item in the schedule -- we didn't talk about this for months. See full log for details (19:21 - 19:47). But the problem isn't that big, so we don't need to hurry (this was before the directfb update happened) - Define rules how SIGs should work - also on the schedule for a long time already. It was agreed on that we don't want to define anything ATM. Just let them work as they like. We can revisit this later if we want/have to. - other discussions (see full log for details): - 19:02 permissions problems with the extras-push scripts should be fixed (mostly) - 19:51 what do people think about multiple maintainers for a single package?; lack of a proposal how to do it exactly - 19:52 emacsen/muse - 19:58 it is not possible to CC the fedora-security mailing list from bugzilla - 20:00 thl, as far as the voting system goes... i have yet to hear anything back from Sopwith Full log 19:00 --- \| thl has changed the topic to: FESCo meeting in progress 19:00 * \| thl looks around 19:00 * \| jima scurries away again 19:00 --- \| Users 70 nicks 19:00 < mschwendt> \| Note to all: FE repodata for 3\|4\|5\|development has been recreated on the master server.

I'm wondering.. how is that intitiative related to what monty talked about over at fudcon? 19:11 < thl> \| warren, it seems jack currently is the bottleneck 19:11 < warren> \| who is jack? 19:12 * \| skvidal just got back 19:12 < mschwendt> \| a package in the queue 19:12 < noa> \| jack is a real time audio pipeline 19:12 < thl> \| jack-audio-connction-foo 19:12 < warren> \| oh 19:12 < warren> \| noa, Noa Resare? 19:12 < tibbs> \| 19:12 < noa> \| warren, yup :) 19:12 < noa> \| warren, long time 19:12 < warren> \| noa, welcome back! You were one of our original contributors. 19:12 * \| noa remembers setting up a bugzilla for fedora in the early days :) 19:13 < warren> \| noa, still running with no security updates! =) 19:13 < thl> \| noa, btw, I don't know "what monty talked about over at fudcon" 19:13 < noa> \| unfortunatly I was sucked up in work and family life for a months 19:13 < thl> \| noa, did I miss anything important? 19:14 < noa> \| thl, it was one of the videos, it seems like he has gotten the task to design an audio daemon that will try to fix many of the problems with audio on linux 19:14 < warren> \| noa, you came to Boston? 19:14 < warren> \| thl, noa: I suspect this has nothing to do with what monty talked about. 19:14 < noa> \| warren, no, i saw the videos over here in sweden 19:14 < warren> \| ah 19:15 < thl> \| noa, k 19:15 < thl> \| anyway, back to the topic 19:15 < noa> \| sorry :) 19:15 < thl> \| tibbs> \| Yes, we need more reviewers. 19:15 < thl> \| that's IMHO one crucial point 19:15 < tibbs> \| I'm trying to do at least two a day, but lately the list has been growing. 19:15 < che> \| thl, what are the requirements for a reviewer? 19:15 < mschwendt> \| thl: the problem with jack is not that we need more reviewers, but that it is not ready. Fernando has commented on the package already. 19:15 < thl> \| and related to " Encourage Extras reviews " -- that's still on the schedule 19:16 < warren> \| thl, adn again I say, "Education" is key to getting more reviewers. 19:16 < bpepple> \| warren: +1 19:16 < thl> \| warren, that's why I brought " Encourage Extras reviews " onto the table 19:16 < thl> \| that's assigned to you warren 19:16 < thl> \| you had plans to update the docs in the wiki 19:16 < tibbs> \| che: you need cvsextras membership, which means package maintainership, which means sponsorship. 19:17 < warren> \| unfortunately I've been unable to prioritize the necessary work to rewrite that entirely myself 19:17 < tibbs> \| Well, fedorabugs membership, but cvsextras is the prerequisite for that. 19:17 < mschwendt> \| tibbs: in short "you need a sponsor" -- package maintainership is not needed 19:17 < cweyl> \| well, "anyone can review", if I recall correctly... it's the _approving_ part that requires cvsextras 19:17 < thl> \| warren, any timeframe when to get this done? 19:17 < thl> \| or is anyone else interested in improving our docs? 19:18 < warren> \| I think it will be an incremental process, and I will need help. 19:19 < thl> \| warren, could you find time to lay down a small and rough plan and ask for help on f-extrs-list? 19:19 < tibbs> \| I'd like to help 19:19 < warren> \| How about I work with tibbs. 19:19 < thl> \| tibbs, can you take care of that together with warren? 19:19 < warren> \| and we create a plan, and ask the list 19:19 < thl> \| warren, tibbs, thx 19:20 < tibbs> \| Sure. Email OK? 19:20 < warren> \| okk 19:20 < thl> \| k, then let's move on 19:20 < thl> \| we'll see if we later if we need more reviews and/or sponsors for the stuff from Planet CCRMA 19:21 --- \| thl has changed the topic to: FESCO Meeting -- Incompatible package upgrade policy 19:21 < thl> \| warren, that's still on the schedule and assigned to you 19:21 < warren> \| Have we really had problems with this? 19:21 < scop> \| yes 19:22 < scop> \| not recently AFAIK, though 19:22 < tibbs> \| One came up last week. Let me think... 19:22 < warren> \| I think "do the right thing" and improved tools to tell us when things break gives us a nice balance between freedom and control. 19:22 < thl> \| improved tools sound like a good idea 19:22 < tibbs> \| I think it was "pan", the newsreader. 19:23 * \| mschwendt must leave for a few mins 19:23 < warren> \| We need the ability to upgrade stuff, because that is the easiest way to fix problems sometimes. At the same time we need the tools to support this, and enforce rebuilding deps when you make such changes. 19:23 < thl> \| I also dislike the plague part in each of the broken deps report for FC3 19:23 < scop> \| tools tend to help within FE only 19:23 < scop> \| thl, so poke the maintainer to do something about it? 19:23 < thl> \| dcbw build plague for FC3 but the dep "createrepo >= foo" is not resolvable 19:24 < thl> \| scop, such packages probably shouldn't even hit the repo 19:24 < thl> \| (in an ideal world) 19:24 < scop> \| right, but if something's broken, it needs to be fixed 19:25 < warren> \| Idea 19:25 < scop> \| "not liking" seeing someting in breakage reports doesn't help alone ;) 19:25 < thl> \| scop, in the case of plague it would require a updated createrepo released as update from core 19:25 < thl> \| scop, sure ;-) 19:25 < scop> \| thl, I know, 19:25 < warren> \| Should the package sign & push process resolve deps and exclude things that break deps? 19:25 < thl> \| warren, yeah, maybe 19:27 < thl> \| scop, thx, didn#t know there was a bug for it open 19:27 < thl> \| warren, would that be possible and easy to do? 19:27 < noa> \| warren, if there is a good mechanism for notifying the affected maintainers I think that would be good 19:28 < skvidal> \| thl: no, it wouldn't be 19:28 < warren> \| per-package CC lists that people can subscribe to would help 19:28 * \| warren files that idea... 19:28 < scop> \| but that's no substitute for a policy 19:29 < mschwendt> \| thl: there is no way to withdraw a built package as it was made available to the build system already 19:29 < thl> \| mschwendt, also true 19:30 < thl> \| maye plague could check if all deps are resolved before pushing a package to the needsign repo 19:30 < thl> \| or does that sound completely silly ? 19:30 < skvidal> \| how about make the pkg owner check for closure before they push out a package 19:30 < tibbs> \| You couldn't rebuild a dependency chain that way, could you? 19:31 < thl> \| and is the problem big enough to discuss it? 19:31 < scop> \| not completely silly, but something that could cause problems in complex build dependency chains 19:31 < thl> \| scop, true 19:31 < mschwendt> \| sounds like we need a QA Checklist again :) 19:32 < thl> \| anyway, back to the original topic: Incompatible package upgrade policy 19:32 < scop> \| no, we need that policy :) 19:32 < thl> \| that what is written in the wiki: 19:32 < thl> \| Seems like we need tools that will allows packagers to 1. notify others when the packager breaks something that others depend on; 2. notify the packager when he's about to break somwthing that others depend on. Warren is working on a proposal. 19:32 < thl> \| anyone any idea how this could be done? 19:33 * \| scop brb 19:33 < mschwendt> \| if you are aware of your package's deps, why not mail the other package owners? 19:33 < warren> \| Combination of written process and automated detection 19:34 < thl> \| "automated detection" seems crucial 19:34 < jima> \| mschwendt: i thought the problem was more not being aware of the dependency problem. 19:34 < jima> \| thl: exactly. 19:34 < skvidal> \| the problem will be two people submitting at the same time 19:34 < warren> \| although skvidal has a good point 19:34 < skvidal> \| you could make them both check for closure 19:35 < skvidal> \| but due to their two pkgs coming out at the same time 19:35 < skvidal> \| they'd have no way of knowing about new deps 19:35 < skvidal> \| or the removal, thereof 19:36 < thl> \| :-/ 19:36 < thl> \| so what do we do? we ignored it for months already 19:36 < thl> \| do we want to continue so? 19:37 < thl> \| and try to fix the things one by one when they show up the next time? 19:37 < warren> \| it hasn't been as much of a problem lately 19:37 < thl> \| agreed 19:37 < tibbs> \| Is it possible to track dependencies and alert maintainers when something new depends on their packages? 19:37 < jima> \| oooo. 19:37 < mschwendt> \| probably with a front-end for repoquery 19:38 < XulChris> \| heya tibbs got your comments on my package, thanks 19:38 < warren> \| basic building blocks like: per package CC list would allow otehr infrastructure to build on top of it. 19:38 < skvidal> \| tibbs: and display it where? 19:38 < tibbs> \| Email? Or just a command-line tool to list stuff that depends on me. 19:38 < tibbs> \| It would at least tell me who I need to keep updated. 19:38 < skvidal> \| tibbs: just add a command to the makefile system to look for what depends on their package 19:38 < jima> \| i'd think email; there's probably no incentive/reminder to run the command. 19:39 < skvidal> \| then they maybe could do: make whatrequires 19:39 < skvidal> \| jima: right, b/c MORE email makes people pay attention 19:39 < skvidal> \| </sarcasm> 19:39 < tibbs> \| Imagine you're Rex. All kinds of stuff is going to depend on Qt4 once it gets in, plus he has like 50 other packages. 19:39 < XulChris> \| tibbs: your comments said my package didnt have a %check section, but it does 19:40 < tibbs> \| XulChris: I'm prone to idiocy. Shoot me the bug #. 19:40 < thl> \| well, I'll mention this discussion in the summary 19:40 < thl> \| maybe some other people have an idea 19:40 < mschwendt> \| Does repoquery have an option to examine _all_ dependencies? 19:41 < thl> \| I'll leave it on the schedule for now 19:41 < \|Jef\|> \| mschwendt: --alldeps 19:41 < mschwendt> \| And this doesn't suffice? 19:41 < mschwendt> \| Sure, one could evaluate owners.list, too, but why? 19:43 * \| thl waits 15 more seconds for further input and will move on if nothing shows up 19:43 < \|Jef\|> \| mschwendt: hmmm alldeps might not be what you want... "check non-explicit dependencies as well" may not mean "walk the dep tree" 19:43 --> \| Eva42 (Unknown) has joined #fedora-extras 19:43 * \| thl waits 20 seconds before moving on 19:43 < mschwendt> \| Walking the entire dep tree is not needed 19:44 < mschwendt> \| Just a beautified display of "my package is used by: A B C D" possibly with owners' email addr in brackets 19:44 < thl> \| mschwendt, maybe we can have that in the planed web-interface 19:44 * \| scop wants to note that no tool the packager can run will help with locally installed stuff or unconfigured 3rd party repos 19:44 < jima> \| no, because the non-explicit deps should be handled when checking the explicit deps' dependencies. 19:44 < jima> \| 12:43 < mschwendt> Walking the entire dep tree is not needed 19:44 < thl> \| awjb had plans for one but didn#t work on it yet (afaik) 19:44 < jima> \| irt that 19:45 < thl> \| k, guys, let's forget about this topic for today and let's move on 19:46 < jima> \| forget about what topic? 19:46 < thl> \| jima, the "Incompatible package upgrade policy" 19:46 < jima> \| thl: _what topic?_ (sorry...) 19:46 < warren> \| It is a bit more complicated and difficult to fix than we can figure out during this meeting. 19:46 < thl> \| warren, exactly 19:47 --- \| thl has changed the topic to: FESCO meeting -- Define how SIGs should work 19:47 < thl> \| that's still on the schedule 19:47 < tibbs> \| The games SIG is running nicely. 19:47 < XulChris> \| what does that mean? 19:47 < thl> \| do we still want do to that or do we just proceed as currrently? 19:47 < XulChris> \| ya i was just gonna say.. 19:48 < warren> \| Aren't SIG's working fine now? 19:48 * \| _wart_ thinks so 19:48 < XulChris> \| well there is some confusion between the music SIG and "sound" SIG 19:48 < thl> \| warren, they are, but we have no real "rules" how they should wroks 19:48 < thl> \| work 19:48 < jima> \| isn't "how do we start up a new SIG?" more the issue? :\| 19:48 < thl> \| the question is: do we need such rules? 19:49 < tibbs> \| SIGs may start to overlap or conflict as more of them appear. 19:49 < _wart_> \| thl: I don't think rules are necessary at this point.

Download presentation 1 Ch 6 Project Analysis Under Certainty Methods of evaluating projects when the future is assumed to be certain. 2 Ch 6 Project Analysis Under Certainty Study objectives After studying this chapter the reader should be able to: Use the NPV model to evaluate projects under certainty Apply the net present value, internal rate of return, payback period and accounting rate of return criteria for investment decision- making under certainty Understand the reasons why the NPV criterion is generally the method of choice for project evaluation Apply the NPV criterion for ranking mutually exclusive projects and project retirement and replacement decisions Use the NPV model to evaluate replacement chain decisions. 3 Certainty Assumption Certainty means that although future flows must be forecast or estimated, the estimated amounts will be received at the times they are expected to occur. Certainty makes the decision simple to model, and the outcome easy to accept. Under the assumption of certainty, future cash flows are to be discounted at a rate which represents the time value of money Returns on risky assets such as stock-market investments contain not only a rate for the time value of money but also a component (a risk premium) to compensate for the risk (or uncertainty) of the expected return. Rates of return on ‘risk-free assets’ are expected to reflect only the time value of money. 4 Certainty Assumption For example: Project Alpha requires an initial outlay of $900, will have cash inflows of $300 in year 1, $400 in year 2 and $600 in year 3. The discount rate is 8% per annum. The calculation is: 5 Certainty Assumption This positive result means that, by undertaking the project, the firm’s wealth will increase by $ Based on the NPV decision rule, the project should be undertaken. We have made several assumptions in formulating and using this NPV model and decision: the amounts of the initial cash outflow and all future cash flows are known with certainty. the discount rate is constant and known with certainty the initial capital outlay occurs at the beginning of year 1 and all operating cash flows occur at year end cash outflows from the firm are treated as negative; cash inflows are treated as positive there are no constraints on the supply of capital, or on other resources the firm will accept all positive NPV projects. 6 Net Present Value. The ideal investment decision making technique is Net Present Value. N P V measures the equivalent present wealth contributed by the investment. NPV is given in NPV -- relates directly to the firm’s goal of wealth maximization -- employs the time value of money -- can be used in all types of investments -- can be adjusted to incorporate risk. 7 Net Present Value. The NPV is calculated by discounting a project’s net cash flows at a specified rate. This rate – often called the discount rate, opportunity cost or cost of capital – refers to the minimum return that must be earned on a project in order to leave the firm’s market value unchanged. 8 Net Present Value. Delta Project The NPV of this project can be computed by evaluating the cash flows. They begin with the initial outlay of $1,002,000 at EOY 0 and continue until EOY 8, at which time the asset salvage value is included. The NPV computation is: 9 Net Present Value. Delta Project With this positive NPV, the project is acceptable. We have used the risk-free rate of 5% per annum as the required rate of return here, as the cash flows are assumed to be certain. 10 Other project appraisal methods While the NPV criterion is the most appropriate method in most cases, the other discounted cash flow technique, the internal rate of return (IRR), is also frequently used, sometimes as a supplementary measure to NPV. 11 Survey Data on CFO Use of Investment Evaluation Techniques CFO Decision Tools Survey Data on CFO Use of Investment Evaluation Techniques SOURCE: Graham and Harvey, “The Theory and Practice of Finance: Evidence from the Field,” Journal of Financial Economics 61 (2001), pp 12 Other project appraisal methods Non-discounted cash flow methods such as payback period (PP) and accounting rate of return (ARR) have a number of serious defects but are still being used in practice in some situations. Sometimes PP is used in conjunction with NPV, particularly in making risky investment decisions. It is useful to understand these methods and their drawbacks so that the most appropriate method can be used for investment evaluation. 13 Other Project Evaluation Techniques: Discounted Cash Flow Techniques Internal Rate of Return – calculates the discount rate that gives the project an NPV of $0. If the IRR is greater than the required rate, the project is accepted. IRR is given as % pa. 14 Internal rate of return Delta Project Using i to represent the IRR, the equation for the IRR calculation using the same cash flows as employed in the NPV calculation (Table 6.1) is: The solution for i, calculated by the Excel IRR function, is 19.80%. Since this rate is above the required rate of 5%, the project is acceptable 15 Internal rate of return The IRR remains in use because decision-makers are used to dealing in ‘rates of return’ rather than the more esoteric NPV. The IRR measure is useful for easily comparing the rate of return from the project being considered with various alternative returns. 16 Other Project Evaluation Techniques: Modified Internal Rate of Return – calculates the discount rate that gives the project an NPV of $0, when future cash flows can be re-invested at the Re-Investment Rate, a rate different from the IRR. If the MIRR is greater that the required rate, the project is accepted. MIRR is given as % pa. 17 Other Project Evaluation Techniques: Non-Discounted Cash Flow Techniques Accounting Rate of Return- measures the ratio of annual average accounting income to an asset base value. ARR is given as % pa. Accounting income is different from cash flow. = % pa. For example, an outlay of $1,000 may earn $200, $500 and $700 as accounting income over three years. The ARR is calculated as: ARR = [ ( ) / 3] / 1000 = 46.66% 18 Other Project Evaluation Techniques: Non-Discounted Cash Flow Techniques Accounting Rate of Return Now the merits of an investment project do not depend on how accountants classify the cash flows and few companies these days make investment decisions just on the basis of the Accounting rate of return 19 Other Project Evaluation Techniques: Payback Period– measures the length of time required to retrieve the initial cash outlay. PB is given as number of years. For example, an outlay of $1,200 may generate cash inflows of $820, $450 and $300 over three years. The total cash inflow to the end of year 2 is $1,270, so the payback period would be within two years. There is no objective time criterion associated with payback, but a period of two to three years would be generally acceptable Payback Period :- Some companies require that the initial outlay on any project should be recoverable within a specified period. 20 Other Project Evaluation Techniques: Payback Period : There are several problems with this measure: The cash flows are not discounted. As the time value of money is not taken into account, the future cash flows cannot be related to the initial outlay. The data outcome is not a decision variable. It does not relate to the firm’s goal of wealth maximization. There is no objective measure of what constitutes an acceptable payback period. Management may set an arbitrary target of say three years, but this value is not objectively related to the firm’s goal. Cash flows occurring after the payback period are ignored. In the case where large outflows may occur on the termination of the project, such as the cost of rehabilitation of a mine site, a project may be erroneously accepted on the basis of a short payback term. Payback is a very unsophisticated and misleading measure, and it is not recommended as a criterion for accepting or rejecting projects 21 Internal Rate of Return Example You can purchase a turbo powered machine tool gadget for $4,000. The investment will generate $2,000 and $4,000 in cash flows for two years, respectively. What is the IRR on this investment? 21 22 Internal Rate of Return Example You can purchase a turbo powered machine tool gadget for $4,000. The investment will generate $2,000 and $4,000 in cash flows for two years, respectively. What is the IRR on this investment? 22 23 Internal Rate of Return IRR=28% 23 24 Internal Rate of Return Pitfall 1 - Lending or Borrowing? With some cash flows (as noted below) the NPV of the project increases s the discount rate increases. This is contrary to the normal relationship between NPV and discount rates. 24 25 Internal Rate of Return Pitfall 2 - Multiple Rates of Return Certain cash flows can generate NPV=0 at two different discount rates. The following cash flow generates NPV=$0 at both IRR% of 8.49% and 31%. Cash Flows (millions of Australian dollars) 25 26 Internal Rate of Return Pitfall 2 - Multiple Rates of Return Certain cash flows can generate NPV=0 at two different discount rates. The following cash flow generates NPV=$A 3.3 million at both IRR% of (-44%) and +11.6%.

The following cash flow generates NPV=$A 3.3 million at both IRR% of (-44%) and +11.6%. NPV 600 IRR=11.6% 300 Discount Rate -30 IRR=-44% -600 27 28 Internal Rate of Return Pitfall 3 – No Internal Rate of Return It is possible to have a zero IRR and a positive NPV #NUM! -210 455 -270 #NUM! 28 29 Internal Rate of Return Pitfall 4 - Mutually Exclusive Projects IRR sometimes ignores the magnitude of the project. The following two projects illustrate that problem. 29 30 Internal Rate of Return Pitfall 4 - Mutually Exclusive Projects 30 31 Internal Rate of Return Pitfall 5 - Term Structure Assumption We assume that discount rates are stable during the term of the project. This assumption implies that all funds are reinvested at the IRR. This is a false assumption. 31 Similar presentations © 2019 SlidePlayer.com Inc.	http://slideplayer.com/slide/4582588/	CC-MAIN-2019-35	refinedweb	1,752	50.57
Is there any way to export an Excel file to a single multi-page TIFF, ie. with each worksheet on a page of the multi-page TIFF? Hi,<?xml:namespace prefix = o Thank you for considering Aspose. Well, your requested feature is not supported at the moment. We have registered your feature requirement in our internal issue tracking system with issue id CELLSNET-13694. We will look into the feasibility of this feature and see if we can support it in our future release. You may check the following documentation link for Sheet2Image feature and Sheet2ImageByPage feature and see if it fits your need. Thank You & Best Regards, Thanks for your reply. I guess I’ll have to use sheetToImage for now, but I’m having trouble getting all the worksheets output to a TIFF. I can get the first worksheet output fine, but the next worksheet throws an exception. I saw example code somewhere for getting all the worksheets in a workbook output to tiff somewhere, but I can’t find it anymore. I’ve determined that the problem is with Sheet2, I get an error that says “Object reference not set to an instance of an object” I’ve attached the file that causes the error. Hi, Thanks for providing us the template file. We found your mentioned issue for SheetToImage method. We will figure it out soon. Your issue has been logged into our issue tracking system with an issue id: CELLSNET-13787. Thank you. Hi, Please try the fix 4.8.2.3 (attached) with the following code: Workbook workbook = new Workbook(); workbook.Open(@"F:\FileTemp\new_fangled_spreadsheet.xls"); workbook.Worksheets["Sheet2"].AutoFitRows(true); workbook.Worksheets["Sheet2"].SheetToImage(@"F:\FileTemp\dest.tiff",true); If you still have any problem, please feel free to contact us. Thank you. The issues you have found earlier (filed as 13787) have been fixed in this update. This message was posted using Notification2Forum from Downloads module by aspose.notifier. That’s great!

These functions are source agnostic and always provide the same interface for all files from cloud storage or local file systems. Buffered cloud objects also support the following features: - Buffered asynchronous writing of any object size. - Buffered asynchronous preloading in reading mode. - Write or read lock depending on memory usage limitation. - Maximization of bandwidth using parallels connections. Example of code: import airfs # Open an object on AWS S3 as text for reading with airfs.open('s3://my_bucket/my_object.txt', 'rt') as file: text = file.read() # Open an object on AWS S3 as binary for writing with airfs.open('s3://my_bucket/my_object.bin', 'wb') as file: file.write(b'binary_data') # Copy file from the local file system to OpenStack Swift airfs.copy( 'my_file', '') # Get size of a file over internet airfs.getsize('') >>> 956 Supported Cloud storage¶ airfs is compatible with the following cloud objects storage services: - Alibaba Cloud OSS - Amazon Web Services S3 - Microsoft Azure Blobs Storage - Microsoft Azure Files Storage - OpenStack Swift airfs can also access any publicly accessible file via HTTP/HTTPS (Read only). Limitations¶ Cloud object storage is not file systems and has the following limitations: - Cloud objects are not seekable in write mode. - Cloud objects must be written entirely at once. - Cloud objects are not locked when accessed. - The cloud object attributes available are more limited.

Hi, Im creating a screenscraper app that takes a users search term, scrapes several 3rd party sites and returns the aggregated results after a few seconds. Rather than wait for all the sites scraping to be completed before showing the results, I want to show the results as they are scraped, ie. when one sites results have been scraped and prepared, they are shown immediately whilst the next set are being done. Initially I thought id just make a scraper function like so def scrape_sites sites.each do \|a_site\| a_sites_results = scrape_and_parse_this_site(a_site) yield a_sites_results end end Then in my controllers js response I could take the results and render them but then i found out htat you cant make multiple render calls in one go. How do i go about doing this? Does this behaviour have a name like say “live search” etc	https://www.ruby-forum.com/t/update-page-with-results-as-they-are-scraped/165005	CC-MAIN-2022-27	refinedweb	143	76.45
Have+. ) — Create multiple insertion points via Ctrl + Alt + Click or add new carets and selections that match the current selection with Shift + Alt + . . - button to request productivity features you need to code with ease and confidence. We are here to help you upgrade! Reason 13: The VS2017 Nuget Package Manager will suck away all happiness in the world, and make developers old and grey, so they forget why they even became developers or why they need salary. Please fix this GUI-nightmare. When having 1 project, then it is okay. When having 3 projects then it gets slow. When having 50 projects then it is like having your hand gnawed off. It constantly re-downloads the entire nuget-repository for every change. It constantly recalculates all dependencies for all projects for every change. Ticking / Unticking all projects for a single nuget-package takes forever without actually requested to install the nuget-package. Hey Rolf, We have been making consistent improvements to NuGet perf with Visual Studio 2017 and are looking at various scenarios we need to make perf gains. Can you help us by sharing more details? You can either use the Send Feedback option on Visual Studio (see for instructions) or send us an email at feedback@nuget.org with the details. Thanks! Should be very easy to reproduce. Just open any solution with more than 10 nuget-packages. It takes forever to display the current nuget packages. It takes forever to show the available updates. The same pattern happens across all solutions and all Visual Studio installations. The first step to make things better would be that it could display all already installed nuget-packages across projects in solution within100 ms and just show the current versions selected in the projects (Without locking the GUI while getting available updates from nuget-sources). Rolf, if you right click on a solution in solution explorer and select ‘Manage NuGet Packages for Solution…’, you can see the currently installed packages (including version numbers) across all projects in a solution. Is this part of what you were looking for? Let me guess, your project(s) are source control -enabled? Somehow Nuget starts bombarding TFS with every single dependency check and if you have a lot of nuget references, updating them can easily take like 10 minutes. And somehow the amount of references seem to exponentially increase the amount of these checks. Doing it without being connected to source control or telling nuget not to care about dependencies solves the problem (not saying that you should). Hi Rolf, While I am aware that updating NuGet packages across the solution takes some time, I haven’t seen the kind of delays you have mentioned here. It would be great if you can provide us with more info and/or a repro to investigate this further as there might be something specific at play here. Thanks, Anand Gaurav I actually dont have that specific problem. I’ve got a about a dozen 50-150 project solutions using public and private nuget packages from multiple repos and its not blazing, but it updates the larger solutions in 2-3 minutes. I do have the problem where nuget pm ui will crash VS in the middle of one of those updates and leave my solution and projects only half updated, and by half updated I mean references removed, but not all re-added back. I end up spending a few hours fixing that because there are other changes pending and I cant just revert to latest. Do you have the problem where it adds app.config files to every project? Or the one where it marks files as pending edits but it does nothing to them? Or the one where it reformats entire .config files but didn’t need to add an assembly binding redirect? Or the one where it cant get along with MSTest and makes MSTest silently skip tests? Or the one where you depend on install.ps1 to cover a gap in nuget’s installation process, or you need to create nuget packages with modifiable content like css or T4, or you want to apply an xdt config transform to add a WCF behavior, only to find those things are all not available with package reference? Or the one where nuget pack changes the version number you specifically put on the package? And a specific nuget team member sees that although 20 people complain on a thread about it, and instead of recognizing it as something that was recently broken and needs to be fixed effectively says “if you want it fixed, fix it yourself”. Or the one where the same nuget team member decides they cannot be bothered to read a thread in another MSFT GH repo to get the repro info needed, and instead demands the user re-enter all the data in the current repo? You have every right to complain and should, but I would take slow and correct over any of the problems I have with nuget. Yes, there are some good new features. Unfortunately, the quality and performance is worse than in VS 2015. The new update policy keeps our developer live thrilling – you never know what the latest update broke this time. There is no way to get back. Quite a lot time needs to be spend finding workarounds for all the VS 2017 bugs :-(. Hey Mike — Can you please use the Send Feedback icon in Visual Studio to share your quality and performance issues? You can find instructions here:. Thanks! Kasey, you cannot be serious. Developer community is even more frustrating than VS itself. exactly but it’s way less embarrassing, they want to pretend it’s all great and anyone struggling with all the bugs must be and anomaly , I’m surprised they haven’t closed comments on this thread yet, if I had an easy way to take my millions of lines of code and many years of effort elsewhere I do it in a heartbeat, it’s would take to an all out war on the incompetence , but it’s never going to happen, the entrenched politically correct and “very nice” yet clueless management isn’t going anywhere, @ M$ everything is awesome, everyone is so nice, UWP is the future, resistance is futile. one of the vunderkids made a post a while back about the GREAT NEW UWP designer and had the audacity to say when it’s mature they will polyfill WPF support, ROLF, can you imagine awesome that going to be? , I’m sure they will be very excited when they it’s released to manufacturing, maybe they can even have a 36 hr hackfest to celebrate! > I’m surprised they haven’t closed comments on this thread yet, The ones that kill me are when folks with fancy titles like Principal Program Manager post about how great VS 15.x preview is going to be, but that never open the comments to begin with. They have to know it will be a justified flame session. I just dont get why they wont acknowledge its been awful for so many, apologize (optional). and address the problems so we can all move on. Instead they keep adding more features (with bugs) and dont go back to fix the existing bugs. I dont have need for most of the new features, There is ~10MM LOC of .net full framework code I need to be able to support for the next 10 years – and I need the bugs in netfx and its tooling to be fixed for that duration. (Industrial/pharmaceutical customers will try to stretch that to 20+ years to save on regulatory related costs) I agree completely. I’ve used VS since the version 6.0 in 1998, and used every version since. I’ve always loved using VS. VS 2017 has had more bugs than 2012, 2013 and 2015 combined. Most of the major updates to 2017 (.1.0, .2.0, .3.0, etc.) had some severe breaking of things. I’m personally on 2017 release 15.5.6 and scared to go to the latest update because I just don’t have time right now to deal with any horrific bugs. It has some neat things, bug quality has gone way down. And just as bad, is the closing of bugs in the Devcommunity site with this answer: “low priority: we don’t have time to fix this right now.” What a horrible answer. Hi @Dean J., I’m really sorry to hear that you’ve had so many issues or bugs with VS2017 through the updates, especially if these are ‘severely breaking’ you. I’d like to try and follow up on these with you, if possible to see if these are known issues we are looking at, or that they have been addressed or are being resolved by the teams here. My email alias at microsoft.com is simoncal, and I’d love to get some specifics from you. Best regards. Preview versions can be installed side-by-side, giving you a way to test new versions before updating your normal version. Here’s one reason not to upgrade, SSDT SSIS is broken in VS2017. From installation woes to packages getting corrupted. We’ll be skipping VS2017 where I work due to this. Hopefully VS2019 will work better and we can upgrade to that instead, but until VS2019 has had a few months to prove that SSIS works consistently we’ll hold off on that upgrade too. Hi, can you help us by sharing the details of the specific issues you have encountered? You can report the issue following this link:. Agree here. Every time I do a version update to VS2017, it breaks SSDT, forcing me to reinstall it. The full version SSDT installer does not work with VS2017 so, you need to install the pieces in a particular order (This is a blog documented process) one at a time and remove things like Analysis services and Reporting services, even though they are reinstalled with an upgrade. Another reason. Who pays for it? The company I work for will not upgrade development software unless we have a contract that pays for it. Until 3 years ago, we were still using VS2005 and 2008. Then we got VS2013 in a contract. We do not qualify to use the community edition of anything. It’s the nature of our business. So, no negative comments please. For what it’s worth, I believe they fixed that finally with the latest SSDT releases, around 15.7.2. Check on the thread here: That said, we’re still sticking on VS 2015 for now specifically because of these problems. I’m hoping we’ll move to VSTS and VS2017 next year. The new features in VS2017 are quite nice, but fast it isn’t. It may well be that the solutions load faster, but this is useful only when I have to restart VS due to its background processes consuming gigabytes of memory or hanging. On the other hand, the editor itself is at times so slow that it’s confusing to type in… Possibly because of intellisense which is also slower – and buggier (misses some possible suggestions, usually the ones in the same namespace as the source I’m typing in). Also, it’s much easier to confuse the syntax highlighting (painting most of your source in red squiggles if you mismatch your parentheses) than in VS2015. And so on… To conclude, it would be very nice if the quality of VS2017 was improved – and it should have been much higher after seven updates – instead of optimizing solution load. Just get it to work right and the management won’t need so much convincing. Hey @bdrajer — Can you please use the Send Feedback icon in Visual Studio to capture your specific problems and performance traces? You can find instructions here:. Thanks, we appreciate your feedback and help! The most difficult argument when convincing the managers is that it’s safe to upgrade – to assure them that no part of the 50.000-line-of-code, 1 mil $ project will no break after re-compiling the code with the new compiler version bundled with the new VS version, and that no breaking changes stay hidden in the new .NET version that also happens to come with the new VS version (especially since MS abandoned side-by-side deployments for full .NET Framework in GAC). Giving a time and money estimate for handling all these risks and running the regression tests across the entire product, this is the most difficult, not convincing them that there are shiny new features. 🙂 What makes running regression tests difficult? I can’t even convince myself to try it again after the last debacle, the only positive thing I can say Is At least your taking comments again, the “closed for comment” posts make it impossible to find out if safe for full time use, the cognitive dissonance on the part of the VS is concerning and make long term planning difficult to say the least , not to mention post like the one stating that the WPF design will be UWP based in the future, all the other relevant Eco-systems are evolving whist VS/.Net remains in a state of MS induced chaos after years of the failed Metro/Modern/Store/Xamarin/Core focused strategy, the title of the post would be humorous and probably is to our competition for the rest of us it’s indication of the sad sad state of affairs .Net/VS world. Sure. Do this if you want to lose your job. VS 2017 is by far the least stable, and most problematic release of VS ever, with (at a point) too many intrusive updates, with regressions. The feedback forum is a joke – because they reject all the issues they cannot reproduce with some simple sample code solution with projects created for the first time. After all these years in product development, these companies do not even know how to reproduce an issue from a customer. We have to “talk” to people who have no technical skills when we log these issues. By now, one would have thought we would have developed tools to automatically get telemetry from a machine which has a customer reported VS issue. Turn this flag on, just keep working and whenever the problem happens, press a button and we will auto send the telemetry to MS. Instead… we are still living in the stone ages, because nobody cares anymore – they get their salary, create 100x new features which PM tells them to do. Why bother with things like getting telemetry when your product is iterating faster than you are capable of iterating it? These people then hire more people like themselves, and after 20 years, you wonder how it got this way. They remove important features from “enterprise” cloud products like Service Fabric without informing anyone – out of the blue – come to the office in the morning, update and see that you cannot create a project within SF you could do the day before. What a joke! I have been using Visual Studio since 1998 – that version back then when the first few versions of VS were released were the best, most stable and reliable. It all went downhill I think since 2010. Nobody should upgrade to this version of VS. Use the one before this, atleast it does not crash and burn like this one all the time. On a side note, this comments feature does not work on the Edge Browser, which MS keeps nagging users to use on Windows. Hey Vijay, Can you elaborate on what you mean by “this comments feature does not work on the Edge Browser”? Hi Vijay, As you might already know, reporting feedback from Visual Studio comes with the ability to record repro and automatically include collected logs. I’m including a couple of links for convenient reference. We are definitely looking for ways to make it easier to include more relevant data with feedback. It will help even further if you are able to share specific cases where the feedback process could have served your needs better. Please reach out to me directly at seiyer at microsoft dot com. We are committed to improving feedback experience and making it productive. Thanks for sharing your thoughts. Our team was using VS 2015 earlier for a LOB UWP app and had to switch to VS 2017 to use the newer UWP features. Here’s what happened after we switched to VS 2017: 1. Our solution build time went from approx. 1 minute to over 2 minutes. I have detailed procmon.exe logs if anyone from Microsoft is interested to look into this. 2. VS 2017 randomly crashes while typing, restarts automatically and then asks if I want to restore the files I was working on ! 3. XAML designer is so unstable that all of us disabled the XAML designer. Instead, we run the app and make changes in the XAML to see how it looks. This mostly works fine when VS 2017 is in a good mood, otherwise not. 4. VS 2017 freezes randomly and shows the finger icon ! 5. Copy/paste keyboard shortcut randomly stops working. Then, I have to do copy/paste using the mouse right click context menu. 6. VS 2017 memory usage goes from under 1 GB to over 2.5 GB in a couple of hours and becomes very slow. 7. Sometimes VS 2017 shows a message that “some advanced features are disabled to improve performance”, but is still slow anyway. Even when I filed a bug report, the response was that the issue could not be reproduced and eventually the ticket was closed. The only advantage with VS 2017 is getting to use the newer UWP SDKs and also the newer C# 7 language features. So I would really recommend anyone who has to use VS 2017 to stick with VS 2015 if possible and spare the trouble. Hi Koshy, Which UWP features did you need that required you to upgrade to visual Studio 2017? For the logs, can you please share with me at dajaco at Microsoft dot com? I’d also love to follow up with you on XAML designer stability related issues. Sincerely, Daniel I just made the mistake of upgrading my Visual Studio 2017 to 15.7.6. Now none of my XAML will work in the designer. Previously it all worked. What happened. Why did you kill the Designer? On all of the 10+ XAML files that I have tried, I get “The XAML Designer has exited unexpectedly.” This is not helpful. Can I go back? There is a setting in Tools -> Options to disable/enable the designer. You may want to toggle it off, close and reopen VS, and try toggling it on again. Or run a repair installation. I had to do the latter when every web form designer I opened did the same. Also if you use R#, it will mess with your XAML settings. Try disabling it if you have it. Thank you for the help. disable/enable of Designer did not help but the Repair fixed the problem. I have a Designer once again. Hi Dick, I’m really curious to understand how you got into the state where the XAML designer stopped working. Could you reach out to me at dajaco at Microsoft dot com so we can dig a little deeper into this issue? Thanks, Daniel I had the same problem. what can I do? if someone using VS 2017 mistakenly migrate to package-reference it means they broke the whole project, now only VS 2017 people can use it. Xamarin team sitting at microsoft (or maybe it’s VS team) are not going to help anything. They just say “give me money, we are developer”, On the another side I never pay a single coin for android studio and it’s work awesome (with hot reload on state). Where are Microsoft think they are going ? ASP.NET MVC to Core, No thanks I will better made it in React and node.js Bot framework, There is plenty of alternative, Luis doesn’t support Hindi, just check github repoistory, LUIS become a joke if you are not using it in English. Blazor (naah, it’s in development) Xamarin, running xamarin like hogging my machine (sound like I am testing processsor for IO, CPU) Load, Same time React native and flutter run smoonthly. Making thing open source was a clever move, but there is better tooling come from outside Microsoft. God know when Microsoft kill thing, Xna, SL, Webmatrix and many other are great example. Even yesterday I was reading about terrible windows update. I was the person who install the update and I see how much creativity microsoft put in making people’s life terrible. If you are serious, Just open Dev essential, I have reported a bug at the time of VS 2017 RC. It’s still in green (pending for release). Few days ago I say what is about that on Github, We will make it release in 2019. very good, I know other company does same but there is something called community and source is all open source internet. Maybe I should call it partially open sourced or totally open sourced. I am using Microsoft think from almost decade but when I using Microsoft tooling , tooling eat all the learning curve and all we seen people doing drag and drop. and a nice joke, Hey john, my xamarin project is not working, Did you tried re-installing nuget package ?, Oh yeah, it’s working, thanks Is this not look creepy. Making thing more complicate is opposite of what Apple CEO say. Breaking thing every day, Just look at the bottom of page, someone saying I just broke my XAML debugger after upgrading to 15.7.6 re: the Xamarin issue resolved by reinstalling the NuGet package, that’s very interesting. We have been working on improving the experience of updating/installing Xamarin NuGets and building. Please help us isolate this issue if this occurs again by using the VS Feedback tool to send us a report that we can dig in to. Thanks! I would recommend everyone who is fed up of VS 2017 and forced to use it daily at work to write an email to the CEO of Microsoft (Satya Nadella) so that he is aware of how bad the quality of the Visual Studio product has degraded. There needs to be more accountability from Microsoft for a paid product like Visual Studio and the team should be answerable to the developers who have to work everyday with this terrible software product. Is there a QA team at Microsoft who tested VS 2017 before releasing it ? Is anyone looking at the hundreds of complaints about VS 2017 that are posted by developers ? We have upgraded Visual Studio to the next major version about the time the next major version is released, making our projects 1 major version behind at all times. Trending with the versions over the last 10 years since 2010, I’ve reduced the tools in VS and add-ons I use due to the breakage, bugs, slow editor, etc. We skipped Silverlight, Lightswitch, UWP, Metro and mobile JavaScript in a browser control technologies because of the high likely hood that they will last 2 to 3 years and then be abandoned by MS (Silverlight). Our current practice is to install a minimal set of NuGet packages for the same reason; namely that over 3 years in the future, quite a few of them will be abandoned or have unfixed critical bugs. It may require a bit more code, though no-one has made a decent business case that library X will save more time in initial production development and the first 5 years of production. Cloud is good, we host basic asp.net MVC c# front-end web sites and c# webAPI sites connecting to a cloud hosted SQL Server. We do not do more in the cloud for the technology longevity risk. Focusing on only the first developer to work on a project and not the cost/effort for post production maintenance is less than helpful. JohnP, you almost don’t need to make the comment, I never bought into such regressive thinking myself, until now that is, beginning to wonder if anyone at Dev Div will ever create anything useful again, UWP can KMA @JohnP, Recently in build 2018, Microsoft was in a way too hurry to release 15.7, 15.6 got too many preview and than released. in 15.7 after 4 preview it’s got in public (maybe to show fake glory of VS 2017 15.7) goes in public with the bugs that I was reported from last few day(s). I have wasted my time reporting bugs and hearing we are working on it, God know what’s going on, In my last comment I am saying I have hold thing from 2017 RC. Now 2019 RC will come in few days. 700 days are much for fixing a release. forget SL, Let’s talk about Windows phone. John, Hey andrew I have windows phone 7, I am interested in Windows phone development, Andew : Buddy, you can’t do that, you need windows 8 and windows 8 phone. John: Oh Andrew I bought a windows 8 phone, now can we got started. Andrew : Sorry, Microsoft released windows 10 , you need windows 10. John, Andrew, See I bought a windows 10 phone, Can we develop windows phone apps now. Andrew, Sorry again, Microsoft is killed windows phone 10, It’s not supported in 2017 as it’s not exist anymore. John, Andrew, What do you suggest now ? Andrew, We can go with xamarin. John, Are development going ok with xamarin. Andrew: I wish we go with flutter or react native. This is the problem with Microsoft, I have revamp 20+ apps in winforms and 1 in WPF (working 6 days in office and 7th in home) in last few month with writing bugs to Microsoft, If I spent my time writing s*** on internet I may become Microsoft MVP. I am not blaming the MVP now, no! I am talking about Quality. I can throw my Android studio and able to write the app that support android 2.2, I have some tablet that is 7-8 years old and have some HW parts working in it, It can be still used for something but Windows phone, God know Where is Microsoft going. I was once bought Lumia 520, fixing a little button cost me 10$, I was sitting at the shop and few days ago Microsoft acquire Nokia, The guard say something to everyone, I don’t clearly remembered but it’s totally stupid to charge someone 10$ for a small thing. fixing a android phone ( for parts) cost less than WP. again I am not blaming WP but what Microsoft did is pathetic. As you can guess from both comment, Like WP god knows when Microsoft shut down UWP, Where is the fluent design?, I have used Material design for web and android but I never seen someone talking about Microsoft fluent for using it in simple html,css website. you’ve got it all wrong, PWA /.core/UWP/XAML Standard, XAML and the Web, the way they where really always meant to be (sound of hip hop inspire background music begins to swell as the stage goes dark , except a lone spotlight on The Man Himself Tech God Joe Belfoire, he begins on a hush almost somber tone , as the stage begin to lighten, “it’s a new day now all your dreams of world domination can come true and with turbo holographic AI now you can just tell Contana what your app is and Machine learning Azure Kubernetees Goodness will write /test and deploy your app to the store, so fast, build times in the nanoseconds, write once run everywhere is yesterdays new, welcome to the bold bold bold new world, we are soooooooooo excited, we can’t what to see all the magical thing you will do with it!” the Build fanishpere erupts in a cheer, “Developers!,Developers!,Developers!” Mature software management for a long lived product like VS should include the following in each release – Adding new features – Fixing bugs – Removing features Removing features has been left off. Therefore, slow, buggy, bloated product with lots of unused features Please post usage metrics on VS features especially the less used ones. Duplicate Line sounds as frustrating as copying and pasting blank lines is. Ctrl+D seems like a good idea for mnemonic shortcut, but Ctrl+D is too close to Ctrl + S or (Ctrl+K, Ctrl + D) for reformatting a document. Isn’t copy paste coding supposed to be “bad”? Quite a bit “borrowed” from R#. How great would it be if it didn’t take 10 minutes to load debugging symbols after you hit F5? That would be so great. Hi Maud, I would like to investigate by it is taking 10 minutes to load debugging symbols for you. Can you email me at vssolutionload at microsoft dot com? Buy new version? What for? I don’t know the world where are you living, but in my world less and less projects are started on .NET stack, and one of the reasons is monstrous tooling which costs $$ every 2-3 years, while there are great platforms with great community which free IDEs which works faster. Hi @AK, I understand your comments about costs and performance speed. I’m curious of your thoughts about whether you’ve considered Visual Studio 2017 Community (a free IDE for students, open source or individual developers), that also allows you to target other stacks, or perhaps Visual Studio Code too? Are these tools not applicable for you or your app app types? Wow, there are some very down comments here. That’s understandable – Engineers are very detail-oriented folks, and if something specific doesn’t work just as specified, it keeps them from doing their jobs. The smallest things cause utter failure. The devil is in the details. I don’t have too much negative to say, though… We have significant portion of a million lines of code in C++ projects and solutions, and if I’m being honest Visual Studio, including the latest 2017, has been pretty good to us in developing it. When VS updates come out we do rebuilds and basic testing in VMs to verify that we can take the updates, and looking back we’ve been able to take almost every update offered. I like that we have the option to choose whether and when to update. Don’t ever think that “automatic” updates would be acceptable. Sure, there have been a few VS bugs but having reported those that are important to us then seeing them fixed in a later release it seems to me the process largely works. That being said, one thing I’ve found frustrating is that the VS developers at Microsoft seem to want to be handed a cut and dried solution showing off the bug. I’ve done that a few times, but you have to understand it’s not trivial to make up something like that. I believe the VS developers should be encouraged to work a little harder when a problem is reported. That would go a long way toward earning respect from the problem submitters. Many of us engineers have good, well setup computer systems that run for months without faults; please take our reports seriously. My one big piece of advice to Microsoft: Slow down! Churning through version after version at breakneck speed means that things never seem to get stabilized. Remember, you’re not producing an end-user application here, you’re producing a TOOL to be used by people to produce applications, and it needs to work perfectly. Not only that, but you need to be able to build your new versions on a solid foundation. Drawing a parallel between being a good software engineer and, say, being a good machinist, weekly releases of Visual Studio would be like loosening the bolts and replacing parts, throwing the alignment of the lathe out of whack constantly. A machinist trying to work in that environment would never manage to get anything done right. QUALITY, not quantity, is going to win the long game. > Sure, there have been a few VS bugs but having reported those that are important to us then seeing them fixed in a later release it seems to me the process largely works. @Noel – Before my developer community account was suspended about 6 months ago, I had logged close to 225 issues since Dec 2016. Out of those issues, only 54 were closed satisfactorily, out of those closures, 12 were questionable but I didn’t feel like arguing over. That puts the Satisfactory Closure Rate between 18% and 24% which I think you would agree is not the hallmark of a process that is largely working. The rest of what you said is spot on about the repro cases () and the tool vendor analogy. I had used the acronym for “Work Time Fun” (or its more common variation) as a tag in the title of issues like this one to flag the ridiculously awful handling of those issues, but I’m not above suspecting that suspending my account was just the fastest way to rid MSFT of a bunch of bugs. ** Despite the suspension, I can still record issues and interact on them using the feedback reporting tool or crafting HTTP Posts w/ fiddler, but the issues no longer get linked to my followed items list so I cant run my report against them to follow up or manage them anymore. I have opened about 50 more issues in this intervening 6 months and the SCR has sadly only decreased. Hi Noel, Thanks for sharing your positive experience around upgrading to newer versions. I was happy to see that. Regarding repro, it will help even further if you are able to share specific instances when it was not trivial. Please reach out to me directly at seiyer at Microsoft dot com and we look forward to learning from those instances and making the feedback experience better going forward. I left VS2017 for VSCode and never to return. That’s actually “Faster than ever”. I won’t develop a Xamarin application ever again. I switched to PWA’s, instead. Hi Moreno, PWA’s can get you really far, quickly, and VS Code is great. I’m glad to hear you’ve found that combination working well for you. I’m curious to learn more about your Xamarin experience. If you have a moment to help us improve the product, please shoot me an email david.ortinau@microsoft.com. I think this is nice design language comparison between the operating systems. See how the new Android is the best? It is very clean but still use colors. W10 is a good second, but has some ugly details like those silly strong borders on search box Nice roll-up article 👍, thanks! So many features in VS 😊 @VS Team – keep up the good work 🚀!! Thanks for the feedback Mike – glad to hear it! 😃 Thank for your solution sharing, I’m done ! Keep going up. Hi All, I really want to see the code & design of their applications (if possible) who are criticizing Visual Studio and Microsoft. I am just thinking how much an individual is technically sound who is commenting so badly on Microsoft’s iconic product. There is always way to overcome the every single problem. Ex – If the solution is not loading for 50 projects then better you split the projects into multiple solution files, do we need to work on all 50 projects in the same solution on daily basis ? Mad person !! I am using Visual Studio from VB 6 onwards, I am very much happy with the Visual Studio IDE & Dot Net framework. It is super easy to design screen, write and debug code. Great technology like MVC, Entity Framework, LINQ, etc and Asp.net core is even great. Over period of time things will change, improve, new things will come. As part of this few things will break which is acceptable to some extent. Why I respect so much Visual Studio because, I find it easy, robust, intelligent. I have seen other IDE also (Swift), really struggled to design simple UI. VS Team, don’t get demotivated by such kind of comments. You guys are great and keep doing good work.. Thank you. If you were a carpenter and bought your tools from the same tool store all of your life, and then the hammers started snapping off at the head and screws disintegrated at random times, would you expect that to be addressed? Would you be upset when the shopkeeper ignored your complaint in favor of a newer potential customer, that is only making a purchase so they can use the restroom? Would you be angry when the shopkeeper pretends like there isnt even a problem? Microsoft is a program authoring tool vendor. Its not about who can make a better program, its about buying a tool that no longer does the job expected of it. > If the solution is not loading for 50 projects then better you split the projects into multiple solution files, do we need to work on all 50 projects in the same solution on daily basis ? Mad person !! 50 projects is a moderate sized solution. I have a few that sized for different products or customer projects, and one in that was 200+ that I’ve trimmed to ~ 150. VS 2015 had no issues with loading any of these. VS 2017 has been fine in regards to solution loading since Lightweight solution load was removed. If you haven’t had to have that much in a single solution, you really arent using enough of the program to see both its best parts as well as the warts. Kid, before you call others mad persons, you better stop calling Swift am IDE and change from your freebie VS to an Enterprise license. Thank you for the positive feedback, glad to hear the tools and frameworks are working well for you. I wish the Visual Studio debugger would let me view variable values in both decimal and hexadecimal simultaneously. When I compute the value of a variable which will serve as an index into a large array, I want to see it in decimal. But occasionally, I store byte values into an array which themselves will be used to index into another array. So I need to dereference the first array and then use the stored value to index into the other array. In that instance, I want to see hex values in the first array. Having to turn hex representation on and off is an annoyance. Another thing: I often find that when I have a breakpoint set, then I remove it by hitting F9, Visual Studio fails to persist that choice for subsequent invocations of the program. Even when I specify File\Save All, I often find that the breakpoint remains set. Thanks for your feedback Robert. Can you please share your idea about showing a variable’s decimal and hexadecimal forms simultaneously at the Visual Studio User Voice site ()? To address your second issue regarding breakpoints, can you please post your concern at the Developer Community site ()? Dang! I’m just switching computers, and I thought it would be a good time to upgrade from VS2015 to VS2017. What am I getting myself into? I’ve been using Visual Studio since 1997, going through VS6, VS2010, VS2015. It’s been pretty reliable, only locking up a couple of times in twenty years. I manage and develop a 500 KLOC C++ old school Win32 “Petzold” style app. I’d rather focus on new features for customers, than new technology. I can’t seem to get the user-defined Intellisense to work. If I ever have to convert, there is a long list of technologies I will consider before UWP (Qt, Javascript). I do want to say in fairness that VS has always been a rock-solid app. It’s my home, it’s where I live, it’s been my companion for twenty years. It’s how I feed my family. Long live VS. @Sprezzatura, you mentioned that you’re having an issue with IntelliSense in VS 2017? Can you give us a few more details on what is the issue you’re seeing? Please follow up at mluparu at Microsoft dot com Btw, this blogpost has a series of tips how to diagnose the issue: but if the issue you’re seeing is a new one, this is likely something we would want to investigate asap. thanks, Marian Shiny Glitter Blah. I actually didn’t read past: “”” May be that the setup is usable when I want to install it fresh on my personal machine over the internet. But we needed to automatically deploy it to 30 developer machines, and that was way more hassle than it should have been. And if something is broken, good luck fixing it, my VS2017 Setup was just hanging and hanging forever on several attempts to do a repair, apparently trying to download gobs of data again. Why you make the offline install for a professional developer tool such a hassle is really beyond me. As usual, the comments section is more informative than the actual post. If there is one single thing wrong with the XAML designer (as there appears to have been in every single “version” of VS 2017), then upgrading is a non-starter. I need a stable XAML designer or I cannot get work done. What’s with all the versions of the Windows 10 SDK? I assume these map to all the useless updates that MS keeps pushing out which just infuriate my users. Computerworld did a survey on user satisfaction with W10. The comments are most illuminating. At this point, I’ve given up on VS 2017, and am hoping there will be better news with VS 2019. Each version of the Windows 10 SDK installs a different Candy Crush game. Hi ThirtyYearsAnMsDeveloper, Do you have any more specifics on the issues with the XAML designer that you have been encountering? I’d love to take a look and understand which issues you’ve been encountering. Each new Windows 10 SDK maps to a new update to the Windows 10 OS – it comes with new APIs and features available to developers that are new in each release. Sincerely, Daniel Hi Daniel What about this: Hundreds of entries, most of them “closed – lower priority” or “closed – not enough information” And the existence of a plugin is Visual Studio Market place solely to kill XAML designer process without restarting Visual Studio is also telling something: Daniel, I installed latest VS 2017 today into a VM running a clean version of Windows 7, and opened one of my current projects, and played around with it. Here’s what happened: 1) At first the designer complained about any element, for example a Window: “Window is not supported in WPF project”. This went away after a while. 2) I opened the toolbox to drop something onto the page, and got the warning: “The Visual C++ Resource Editor Package did not load correctly”. 3) I could not search in the property page (this is actually a bug from VS 2015 that I was really hoping you would have fixed by now). 4) The designer crashed: System.NullReferenceException Object reference not set to an instance of an object. at Microsoft.VisualStudio.DesignTools.Designer.Metadata.MetadataStore.GetTypeConverter(Type type) at Microsoft.VisualStudio.DesignTools.WpfDesigner.Metadata.WpfDesignTimeProperties.RegisterProperty(IPropertyId neutralPropertyKey, IType declaringType, FrameworkPropertyMetadataOptions options, PropertyChangedCallback callback) at Microsoft.VisualStudio.DesignTools.WpfDesigner.Metadata.WpfCommonDesignTimeProperties.Initialize(WpfDesignTimeProperties designTimeProperties) at Microsoft.VisualStudio.DesignTools.WpfDesigner.Metadata.WpfDesignTimeProperties..ctor(RuntimePlatformMetadata platformMetadata) at Microsoft.VisualStudio.DesignTools.WpfDesigner.Metadata.WpfPlatformMetadata.Initialize() at Microsoft.VisualStudio.DesignTools.WpfDesigner.WpfPlatform.get_Metadata() at Microsoft.VisualStudio.DesignTools.XamlDesigner.Metadata.XamlProjectMetadata..ctor(XamlProjectContext projectContext, ProjectAssemblyResolver projectAssemblyResolver, IUnbuiltTypeDescriptionProvider unbuiltTypeDescriptionProvider) at Microsoft.VisualStudio.DesignTools.XamlDesigner.Documents.XamlProjectContext.CreateRuntimeProjectMetadata() at Microsoft.VisualStudio.DesignTools.Designer.Documents.Project.ProjectContextBase.InitializeProject() at Microsoft.VisualStudio.DesignTools.XamlDesigner.Documents.XamlProjectContext.InitializeProject() at Microsoft.VisualStudio.DesignTools.Designer.Documents.Project.ProjectContextBase.Initialize(IHostProject project, Action cancelCallback) at Microsoft.VisualStudio.DesignTools.Designer.Documents.Project.ProjectContextManager.GetProjectContext(IHostProject project, IPlatform platform, Boolean create) at Microsoft.VisualStudio.DesignTools.Designer.Documents.Project.ProjectContextManager.d__94.MoveNext() at Microsoft.VisualStudio.DesignTools.XamlDesigner.Commands.ReplaceStyleTemplateCommand.ResolveDefaultStyle(SceneNode targetElement, Object defaultStyleKey, Boolean allowDefaultStyle, DocumentNode& currentStyle, Boolean& isThemeStyle, IList`1& auxiliaryResources) at Microsoft.VisualStudio.DesignTools.XamlDesigner.Commands.ReplaceStyleTemplateCommand.ProvideCurrentStyle(SceneNode targetElement, IType targetType, PropertyReference targetPropertyReference, Boolean allowDefaultStyle, IList`1& auxiliaryResources) at Microsoft.VisualStudio.DesignTools.XamlDesigner.Commands.EditCopyOfStyleCommand.get_IsEnabled() at Microsoft.VisualStudio.DesignTools.Utility.Commands.Command.GetProperty(String propertyName, Object defaultValue) at Microsoft.VisualStudio.DesignTools.XamlDesigner.Commands.ReplaceStyleTemplateCommand.GetProperty(String propertyName) at Microsoft.VisualStudio.DesignTools.Utility.Commands.CommandTarget.c__DisplayClass21_0.b__0() at Microsoft.VisualStudio.DesignTools.Utility.ProtectionZone.DummyProtectionZone.Execute[T](Func`1 func) at Microsoft.VisualStudio.DesignTools.Utility.Commands.CommandTarget.GetCommandProperty(String commandName, String propertyName) at Microsoft.VisualStudio.DesignTools.Designer.Views.SceneView.UpdateCommandState(IEnumerable`1 commandNames, Boolean forceRefresh) at Microsoft.VisualStudio.DesignTools.Designer.Views.SceneView.SelectionManager_LateActiveSceneUpdatePhase(Object sender, SceneUpdatePhaseEventArgs args) at Microsoft.VisualStudio.DesignTools.Designer.ViewModel.SceneUpdatePhaseEventHandler.Invoke(Object sender, SceneUpdatePhaseEventArgs e) at Microsoft.VisualStudio.DesignTools.Designer.ViewModel.Selection.SelectionManager.FireLateActiveSceneUpdatePhase(SceneUpdatePhaseEventArgs args) at Microsoft.VisualStudio.DesignTools.Designer.Views.SceneViewUpdateScheduleTask.UpdateLate() at Microsoft.VisualStudio.DesignTools.Utility.Scheduler.ScheduleTask.Update() at Microsoft.VisualStudio.DesignTools.Utility.Scheduler.SchedulingService.DispatchTasksAtPriority(DispatcherPriority priority) at Microsoft.VisualStudio.DesignTools.Utility.Scheduler.SchedulingService.DispatcherToken.Dispatch(Object arg).Application.RunDispatcher(Object ignore) at System.Windows.Application.RunInternal(Window window) at System.Windows.Application.Run(Window window) at Microsoft.VisualStudio.DesignTools.DesignerContract.Isolation.DesignerProcess.RunApplication() at Microsoft.VisualStudio.DesignTools.DesignerContract.Isolation.DesignerProcess.c__DisplayClass3_0.b_() My entire evaluation has lasted less than 20 minutes. If you want convince us to upgrade >300 dev seats, lets start with the basics: Provide a usable installer to deploy VS automated to hundreds of machines. The existing one is a mess and we gave up after 3 days of trying to get a fully automated offline installation using /layout et al. Yes, we reported it, yes its on user voice, and no, MSFT does not care. TEST YOUR STUFF before shipping it. And I’m not talking about running some artificial unit tests to have pretty green colors in your dashboards. I’m talking about actually using the XAML designer and see it crashing all the times. I’m talking about using the C++ debugger and see it blocking for 5 seconds after hitting F5. I’m talking about 15.7.5 introducing C++ compiler optimization bugs causing obscure crashes. I’m talking about using the Forms Designer on a highDPI screen and not only having it’s UI falling apart, but also messing up generated C# code with wrong UI element sizes. We don’t have the budgets to pay our devs to use uncountable hours the fiddle with VS instead of getting actual work done. The install updates every 10 day and figure out what broke this time. And especially not to find and report bugs in your expensive VS product on our expense. I’d gladly switch to 2017, but I have projects with silverlight and they won’t load. Our clients are on windows 7 and I hear the editor has been gimped for WPF. VS 2017 was the first version that we weren’t able to use due to the removal of legacy support. After 20 years, we are planing to cancel our VS Enterprise subscriptions because we have spent thousands and haven’t been able to use it. Microsoft hasn’t inspired people to upgrade or has made windows 10 a poor investment for enterprises. Native windows developers are like me are in a difficult situation. luck you being able to just move on. Just a current example: VS15.8 broke the VC++ resource editor completely on Windows 7. It does not even start. So customer like us, having a lot of MFC application still in maintenance, can’t work anymore. We develop on Windows 7 Enterprise, because that’s what about 2/3 of our customers use. Of course one can argue they should migrate to Windows 10. But convincing Windows customers to upgrade to Win10 is MSFT’s job. We can’t. Our SW has to work on what the customers are using. Or we’re out. Having that sad, the root cause of this bug () is nothing to convince any management to use VS2017: With an 15.8 early preview, a dependency to an API introduced with Windows 8 was added to the VS2017 VC++ resource editor. And this obviously was unnoticed and made it into the official release. Win7 is still an officially supported platform for VS2017. But MSFT developers add dependencies to APIs not available on Win7 and obviously during testing of VS2017 15.8 the VC++ resource editor was not started a single time on Win7. That’s not acceptable.

I've had fun developing this control and believe it will be useful for many reasons. The first and foremost reason is to get a good peer review. The second is to help share ideas, coding, and of course the code itself. I've been interested in chess for about 7 years now and you can say I'm quite addicted. The positive note is my wife would rather see me out playing chess on a Friday night vs drinking in a bar. I was about 80% done with my code when I noticed that Chris R. Chapman had put out his version of a control, using the famous Bitboards (Good job Chris!). So any one interested should check out his control as well. There are two main differences that you will note: Chris pre generates his attack boards where as I generate mine on the fly, I draw the chess board in an offscreen buffer then splash it to the screen, and finally I trap the mouse clicks and locate the corresponding squares. In regards to the Bitboards I've always been curious to the differences in speed between the two approaches. There has been some arguments in the online 'chess' groups that the pre-generated versions are no faster than the build as you go, I personally have not tested this but now maybe I can. I've found my code to execute very nicely and do not see any performance problems. I believe if I change anything in performance it would be the mouse click / square location routines. I think simply dividing the board into quarters and associating each quarter with the underlying squares should speed things up some, but to be honest it runs pretty fast now so I may be lazy and skip this part. I have successfully validated quite a few different and weird checks, mates, and stalemates so I believe the move validation is pretty solid. If you find any problems let me know, email me FEN strings. You can find some of the FEN strings in the header for StandardValidation.isKingCheckedMatedStaled method. StandardValidation.isKingCheckedMatedStaled I draw the chess board in the background and then splashed to the screen and this gives me pretty smooth piece movement. The intentions here were to give the drawing code the ability to be called from a web server for display on an HTML page. That's why it's hooked up to the FEN events, pass the string and generate the graphics. See below discussion on events. There is also a PGN brute force parser that has example code in the demo program that converts the PGN to XML. It will save the file into the same location as the PGN but with the .XML extension. The intent here was to use the XML for the format in the background for displaying, navigating, and annotating chess games. It can also be used to display an annotated game in HTML with a little XSL processing (if anyone writes one let me know). I have some example pgn files saved in the directory with the control for testing, a couple with multiple variations and comments. The game navigation is the next thing I'm going to work on finishing. Please be aware that I'm unsure how the XML parser will work with a totally junked file and I have not tested it 100% as I'm just starting to working on the game navigation control. Note the VCR buttons do not move through a game yet. I'm working on that in my spare time utilizing the XML generated above. There is some cleanup I still need to perform so don't be too critical of the code. I would recommend that you read articles on Bitboards and their use in chess computer. Crafty source code is an insane place to look if you enjoy reading C code. But the easiest method is to perform a simple search on the topic. But beware, you may get redirected to this very column where you will find yourself in a never ending do/while loop. Seriously though I hope to show a use of interfaces and events in my first attempt and this article. In regards to interfaces and events, I find that they go very well together. I first think of the events I want a particular object to implement, then I group these event methods into an interface. I then define a bare minimum interface for the object itself in which I declare two methods: addEvents(ievents) and removeEvents(ievents) where the parameter ievents would be the event methods/interface I previously created. The body of the methods addEvents() and removeEvents() simply hook/detach up all of the methods defined in the interface to the object producing the events. addEvents(ievents) removeEvents(ievents) ievents addEvents() removeEvents() To better understand my point look at the code in the file ChessInterfaces.cs. In particular find the IPosition and IPositionEvents interfaces. The IPosition defines the methods that a class must implement to allow the events defined in IPoisitionEvents to be hooked up and ready for action. Thus in the interface IPosition we have the two methods named: IPosition.removeEvents(IPositionEvents ievents) and IPosition.addEvents(IPositionEvents ievents). Now open up the file FenNotation.cs. Here you will find public class FenNotation : IPosition which wants other classes to be aware of his ability to parse a FEN string. Now open up the two files ChessBitmap.cs and StandardValidation.cs to reveal the following: public class ChessBitmap : IPositionEvents and public class StandardValidation: IPositionEvents, IValidation . Making sense yet? Ok just a little more to go. Once you've studied the aforementioned code, mainly the addEvents / removeEvents, open the file: ChessBoard.cs and find the code in the constructor: IPosition IPositionEvents IPoisitionEvents IPosition.removeEvents(IPositionEvents ievents) IPosition.addEvents(IPositionEvents ievents) public class FenNotation : IPosition public class ChessBitmap : IPositionEvents public class StandardValidation: IPositionEvents, IValidation addEvents removeEvents coFen = new FenNotation(); // Assign our graphical and bit board to // the FEN class so that we can // capture the events. coFen.addEvents(coChessBitmap); coFen.addEvents(coBitBoard); Now you should be able to see what we've accomplished here: First with a little bit of extra work I've made it very simple for others to use the events of my object, Second I've made it very easy for me to use the events of my object. To create another object that listens to the events I simply declare an object and have it implement the interface for the events that I am interested in receiving. Remember VS will ask you if you want the interface skeleton code generated, simply say yes and write the body of the code to handle the events. Then it is a simple function call to hook that object up to receive events. For another example look at the PGN parser and the XML conversion that takes place in the sample applications. Couldn't get any easier: Compile the projects and let em rip.... Seriously though it is that easy. Just open the solution in the ChessBoardCtrl directory named: ChessBoardCtrl.sln. This solution has references to the demo applications that hosts the control and implements some of the features. By looking at the demo program you can get a good understanding of how the control works, play with that first then try it your self. I'll update this more at a later time (when I have a little more time). Until then let me know what you guys think! CHEERS!

Issues with setting checkboxes in QSqlTableModel I have subclassed QSqlTableModel so I can add checkboxes to a QTableView. I've done this by overriding the flags(), data() and setData() methods. When the tableview loads the data from SQL it seems to work fine and does set the checkboxes accordingly. But when I click on the checkboxes nothing happens to either the data in the database, or the checkbox in the view. Here's what I'm doing currently in my setData method: def setData(self, index, value, role=Qt.EditRole): if role == Qt.CheckStateRole\ and self.headerData(index.column(), Qt.Horizontal) in \ ("Game", "Console", "Accessory", "Box", "Manual"): data = "Yes" if value == Qt.Checked else "No" return QSqlTableModel.setData(self, index, data, Qt.EditRole) else: return QSqlTableModel.setData(self, index, value, role) Basically I'm checking if the role is CheckStateRole and if the column is in the column I have the checkboxes in. Then checking the value and passing the correct data to the database based on it. It does enter the if statement, and checking the value of data seems like it does set it correctly. So the part that doesn't work is the call to QSqlTableModel.setData() in the return statement. It doesn't seem to do anything. Editing columns that don't have checkboxes works fine. Am I doing something obviously wrong here? - VRonin Qt Champions 2018 last edited by I'm not a python expert but QSqlTableModel.setData(self, index, data, Qt.EditRole)looks wrong. To call the base class implementation you should call something like super(QSqlTableModel,self).setData(self, index, data, Qt.EditRole) @VRonin I'm pretty new to python myself, as well as QT, so I'm admittedly a bit unsure as to the difference between what I was doing and using super like that. Thanks for pointing it out. I should look into it more. I changed the whole subclass to use super() but it still has the same behavior unfortunately. :( Edit: Actually now I can't edit any other column either. I guess that makes it consistent at least. But it doesn't make sense. Reading up on super() the way I was doing it is simply how you do it without using the super function, and the way it was done before super was introduced in Python. The behavior should be identical if I'm reading it correctly. But obviously something changed. Maybe someone can chime in on that. Edit²: Ok never mind the previous edit. Changing super(QSqlTableModel, self) into just super() everywhere (for example super().setData(index, data, Qt.EditRole) made the behavior exactly as when I used QSqlTableModel to call the base implementation. That is, I can edit the columns that don't have checkboxes but the checkboxes are still not co-operating. So I took a look at the QSqlTableModel C++ source code, and I noticed that there's an if statement in there that checks if the index has the flag ItemIsEditable set. If it isn't, then it returns false. Now in the example I was adapting from (Which was this one that is subclassing a QSortFilterProxyModel rather than QSqlTableModel, and was using boolean values and doing other things as well) did NOT set that flag in the overridden flags() method! I assume that's done somewhere else, but I only adapted what I needed. I didn't even know it was a flag you could set since I've never really done this before. Should've looked more carefully at the example I guess... Anyway, after setting that flag in the flags method it now works as expected. Here's what the method is looking like now if anyone is interested: def flags(self, index): if self.headerData(index.column(), Qt.Horizontal) in ("Game", "Console", "Accessory", "Box", "Manual"): return Qt.ItemIsUserCheckable \| Qt.ItemIsSelectable \| Qt.ItemIsEnabled \| Qt.ItemIsEditable else: return super().flags(index) You can also set the return statement to simply: return super().flags(index) \| Qt.ItemIsUserCheckable And it'll work just the same. That's actually probably a better/cleaner way of doing it now that I think about it.	https://forum.qt.io/topic/98007/issues-with-setting-checkboxes-in-qsqltablemodel	CC-MAIN-2019-43	refinedweb	689	59.3

ETK + Enhance, quick and dirty ETK is a gui toolkit similar to gtk and is a part of Enlightenment Foundation Libraries or EFL. The syntax is very similar to GTK with only minor differences. Infact you could even use Glade to design GUI with ETK. For this you need a small but nifty tools called ‘enhance’ also part of E. Glade btw is a tool which removes the need of manipulating each and every widget manually. It does all these in an efficient manner leaving the developer to concentrate only on callbacks. I am very new to ETK+Enhance and dont know which is better. EWL or ETK. If someone could shed light on this, I would be grateful. Myself, being a novice found the lack of documentation for enhance a bit unnerving. But still I managed to get hold of the concepts. So here is a short tutorial about using ‘enhance’ to parse your .glade files and use them in your etk source codes. Comments are welcome. I assume some knowledge in ETK or atleast GTK…Lets dig in.. Now create a glade file with the name of project1.glade. Create a simple window with a single button in it. Now in the property window of the button in the Signal tab, add the following information Signal->Clicked, Handler-> , in our case “button_callback” The following code is the famous hello world program using ETK and glade for creating the GUI.. #include "Etk.h" #include "Enhance.h" Enhance en; void button_callback(Etk_Object obj, void data) { printf("Whee THis works\n"); } int main(int argc, char argv[]) { enhance_init(); etk_init(&argc, &argv); en=enhance_new(); enhance_file_load(en, "window1", "project1.glade"); etk_main(); enhance_free(en); enhance_shutdown(); etk_shutdown(); return 0; } Ok now a step by step description of whats up #include "Etk.h" #include "Enhance.h" Enhance en; We are just including header files that is required for our program..duh! Anyway the third line, we are creating a pointer for the Enhance datatype. ‘en’ will be used while loading our .glade file void button_callback(Etk_Object obj, void *data) { printf("Whee THis works\n"); } The above function is the callback function. When we click the “button” of our program the line within the printf would output to the console. If you dont understand what I am tallking about visit the gtk website and download the tutorial to get an idea of what callbacks and widgets are. enhance_init(); etk_init(&argc, &argv); We are initialising enhance and etk.. en=enhance_new(); Remember the pointer ‘en’ of datatype Enhance. en now becomes a new instance of enhance.. enhance_file_load(en, "window1", "project1.glade"); The above line will load the widget “window1″ from the “project1.glade” file and “en” will point th them. You should load each widget, for example, you may have more than one window in your .glade file. The remaining lines are self-explainatory..:D Save the file as hello.c, in the directory containing project1.glade..and compile the program gcc -g hello.c -o hello `enhance-config --libs --cflags` `pkg-config --libs --cflags` If all went well, you will be left with the executable called “hello”.. run it ./hello You will get a small window with the button with E17 theming containing the label you had specified while creating the gui with glade. Click on the button and you will see the text “Whee THis works” output on the console everytime it is clicked. Reference: E Developers Portal Glade and GTK+ If you find something wrong, which is mostly likely, please comment about them. I am learning ETK/enhance myself. Filed under: FOSS and Linux, Tips \| 7 Comments It depends on preference. ETK is similar to GTK. So, if you like GTK you’ll probably like ETK. If, like the EWL developers, you don’t like the GTK API that much you might want to look at EWL. With EWL we started from a blank slate and are attempting to make a simple and consistent API. EWL makes extensive use of inheritance and callback methods to reduce code duplication inside the core code. You can get some info on EWL at wiki.edevelop.org/index.php/EWL there are a set of introductory tutorials to get people started. (Note, as disclaimer, I’m an EWL developer.) cool gcc -g hello.c -o hello `enhance-config –libs –cflags` `etk-config –libs –cflags` etk-config doesn’t exist, now the right command with etk-config is: gcc -g hello.c -o hello `enhance-config –libs –cflags` `pkg-config –libs –cflags etk` @arcano: thanks, updated the post hello, since i’m studying C/C++/Enlightenment programming and also build systems too(cmake in that case), i’ve made the smallest possible (i presume) CMakeLists.txt able to compile that example: # CMakeLists.txt project(helloEtk) include_directories(/usr/include/etk) add_executable(helloEtk helloEtk.c) target_link_libraries(helloEtk exml etk ecore_file edje ecore_x ecore_fb curl evas ecore enhance) but i have a question: if i modify the source to call all that free/shutdown stud inside the callback my console don’t returs to me; why the process don’t quit? i’m using SlackE17, any idea if it’s a bug? @Sombriks: Yo, I haven’t been really following changes to EFL for a while, maybe the post is too outdated…However you could hop onto #edevelop at freenode if you haven’t already…its a pretty friendly channel…:D If you are having problems loading dynamic callbacks, use the -rdynamic flag for gcc	http://sudharsh.wordpress.com/2006/11/10/etk-enhance-quick-and-dirty/	crawl-002	refinedweb	911	66.03
This is not the current version. View the latest documentation Realm Java enables you to efficiently write your app’s model layer in a safe, persisted and fast way. Here’s what it looks like: // Define you model class by extending the RealmObject public class Dog extends RealmObject { @Required // Name cannot be null private String name; private int age; // ... Generated getters and setters ... } public class Person extends RealmObject { @Required // Name is not nullable private String name; private String imageUrl; // imageUrl is an optional field private RealmList<Dog> dogs; // ... Generated getters and setters ... } // Use them like regular java objects Dog dog = new Dog(); dog.setName("Rex"); Log.v(TAG, "Name of the dog: " + dog.getName()); // Get a Realm instance for this thread Realm realm = Realm.getInstance(context); // Persist your data easily realm.beginTransaction(); realm.copyToRealm(dog); realm.commitTransaction(); // Query and use the result in another thread Thread thread = new Thread(new Runnable() { @Override public void run() { // Get a Realm instance for this thread Realm realm = Realm.getInstance(context); Dog dog = realm.where(Dog.class).equalTo("name", "Rex").findFirst(); Log.v(TAG, "Age of the dog: " + dog.getAge()); realm.close(); } }); thread.start(); Getting started Download Realm for Android or see the source for realm-java on GitHub. Prerequisites - We do not support Java outside of Android at the moment. -.84.1'to the dependencies of your project - In the Android Studio menu: Tools->Android->Sync Project with Gradle Files Jar - Download the release package and unzip. - Copy the jar file and folders (containing the librealm. ProGuard Realm generates a proxy class for each RealmObject at compile time. To ensure that these classes can be found after running an obfuscation and static analysis tool like ProGuard add the configuration below to your ProGuard configuration file. Your Realm version needs to be 0.84.1 or higher. -keep class io.realm.annotations.RealmModule -keep @io.realm.annotations.RealmModule class * -keep class io.realm.internal.Keep -keep @io.realm.internal.Keep class * { ; } -dontwarn javax.* -dontwarn io.realm.** Realm Browser The Realm Browser is only available on Mac OS X at the moment. We are working on Windows & Linux versions.. If you’ve already updated to Realm Java 0.83, there is a compatible pre-release version of the Browser on the Realm Browser GitHub page. API Reference You can consult our full API reference for all classes, methods & more.ThreadExample is a simple app that shows how to use Realm in a multithreaded environment. The RealmAdapterExample shows how to use the RealmBaseAdapter to bind RealmResults to Android lists in a convenient way. The RealmJsonExample illustrates how to use the new Realm JSON facilities. The RealmEncryptionExample shows you how to work with encrypted Realms. by implementing something very similar to a traditional Java Bean. Simply extend our RealmObject class and let the Realm annotations processor generate proxy classes. overridden by the generated proxy class used in the back by RealmObjects, so any custom logic you add to the getters & setters will not actually be executed. Field types Realm supports the following field types: boolean, byte, short, int, long, float, double, String, Date and byte[]. The integer types byte, short, int, and long are all mapped to the same type ( long actually) within Realm. Moreover, subclasses of RealmObject and RealmList<? extends RealmObject> are supported to model relationships. The boxed types Boolean, Byte, Short, Integer, Long, Float and Double can also be used in model classes. Using these types, it is possible to set the value of a field to null. Required fields and null values In some cases, null is not an appropriate value of a field. The @Required annotation can be used to tell Realm to enforce checks to disallow null values. You don’t have to add @Required to fields of primitive types as these cannot be null. Ignoring properties The annotation @Ignore implies that a field should not be persisted to disk. Ignored fields are useful if your input contains more fields than your model, and you don’t wish to have many special cases for handling these unused data fields. Indexing properties The annotation @Index will add a search index to the field. This will make inserts slower and the data file larger but queries will be faster. So it’s recommended to only add index when optimizing specific situations for read performance. We support indexing: String, byte, short, int, long, boolean and Date fields. Primary keys To promote a field to primary key, you use the annotation @PrimaryKey, and the field type has to be either string or integer ( short, int or long). It is not possible to use multiple fields (compound key) as a primary key. Using a string field as a primary key implies that the field is indexed (the annotation @PrimaryKey implicitly sets the annotation @Index). Using primary keys makes it possible to use the createOrUpdate() method, which will look for an existing object with this primary key, and update it if one is found; if none is found, it will create a new object instead. Using primary keys has an effect on the performance. Creating and updating object will be a little slower while querying is expected to be a bit faster. It is hard to give numbers as the changes in performance depend on the size of your dataset. When calling Realm.createObject(), it will return a new object with all fields set to the default value. In this case, there might be a conflict with an existing object whose primary key field is the default value. To avoid this, it is suggested to create a standalone object, set values of the fields, and then copy it to Realm by copyToRealm() method. MyObject obj = new MyObject(); obj.setId(42); obj.setName("Fish"); realm.beginTransaction(); // This will create a new one in Realm // realm.copyToRealm(obj); // This will update a existing one with the same id or create a new one instead realm.copyToRealmOrUpdate(obj); realm.commitTransaction(); Primary keys cannot have the value null, and the @PrimaryKey annotation has the @Required annotation implicitly. Limitations Due to how the proxy classes override getters and setters in the model classes there are some restrictions to what is allowed in a model class.(); While working with your RealmObjects inside a write transaction, you might end up in a situation where you wish to discard the change. Instead of committing it, and then reverting it, you can simply cancel the write transaction: realm.beginTransaction(); User user = realm.createObject(User.class); // ... realm.cancelTransaction(); Please note that writes block each other, and will block the thread they are made on if other writes are in progress. This can cause ANR errors if you are doing writes from the UI thread while also doing writes from a background thread. To avoid this, first create objects in memory first outside a transaction, and only perform a simple Realm.copyToRealm() inside the transaction, which will keep blocking times to a minimum. Thanks to Realm’s MVCC architecture, reads are not blocked while a write transaction is open! This means that unless you need to make simultaneous writes from many threads at once, you can favor larger write transactions that do more work over many fine-grained write transactions. When you commit a write transaction to a Realm, all other instances of that Realm will be notified, and the read implicit transactions will refresh your Realm objects automatically. Please note read & write access in Realm is ACID. Creating objects Because RealmObjects are strongly tied to a Realm, they should be instantiated through the Realm directly: realm.beginTransaction(); User user = realm.createObject(User.class); // Create a new object user.setName("John"); user.setEmail("[email protected]"); realm.commitTransaction(); Alternatively you can create an instance of an object first and add it later using realm.copyToRealm().(); When using realm.copyToRealm() it is important to remember that only the returned object is managed by Realm, so any futher changes to the original object will not be persisted. Transaction blocks Instead of manually keeping track of realm.beginTransaction(), realm.commitTransaction(), and realm.cancelTransaction() you can use the realm.executeTransaction() method, which will automatically handle begin/commit, and cancel if an error happens. realm.executeTransaction(new Realm.Transaction() { @Override public void execute(Realm realm) { User user = realm.createObject(User.class); user.setName("John"); user.setEmail("[email protected]"); } }); Asynchronous Transactions As transactions are blocked by other transactions it can be an advantage to do all writes on a background thread in order to avoid blocking the UI thread. By using an asynchronous transaction, Realm will run that transaction on a background thread and report back when the transaction is done. To switch from a synchronous transaction to an asynchronous transaction, add the Realm.Transaction.Callback parameter. realm.executeTransaction(new Realm.Transaction() { @Override public void execute(Realm bgRealm) { User user = bgRealm.createObject(User.class); user.setName("John"); user.setEmail("[email protected]"); } }, new Realm.Transaction.Callback() { @Override public void onSuccess() { } @Override public void onError(Exception e) { // transaction is automatically rolled-back, do any cleanup here } }); The callback is optional, but if provided it will be called when the transaction completes or fails. Callbacks are controlled by the Looper, so only null callbacks are allowed on non-looper threads. RealmAsyncTask transaction = realm.executeTransaction(new Realm.Transaction() { @Override public void execute(Realm bgRealm) { User user = bgRealm.createObject(User.class); user.setName("John"); user.setEmail("[email protected]"); } }, null); An asynchronous transaction is represented by the RealmAsyncTask object. This object can be used to cancel any pending transaction if you are quitting the Activity/Fragment before the transaction is completed. Forgetting to cancel a transaction can crash the app if the callback updates the UI. public void onStop () { if (transaction != null && !transaction.isCancelled()) { transaction.cancel(); } }. Objects are not copied - you get a list of references to the matching objects, and you work directly with the original objects that matches your query. The RealmResults inherits from Java’s AbstractList, and behaves in similar ways. For example, RealmResults are ordered, and you can access the individual objects through an index. When a query does not have any matches, the returned RealmResults object will not be null, but the size() method will return 0. If you wish modify or delete any of the objects in a RealmResults, you must do so in a write transaction. Retrieving objects by type The most basic method for retrieving objects from a Realm is realm.allObjects(), which returns a RealmResults of all instances of the model class being queried. There are specialized versions of allObjects() which offer sorting functionality i.e., you can specify sorting order per field. See realm.allObjectsSorted() for details.(); Futhermore, it is possible to negate a condition with not(). The not() operator can be used with beginGroup()/ endGroup() to negate subconditions only. Sorting Once you have done your query, you can sort the results like this: RealmResults<User> result = realm.where(User.class).findAll(); result.sort("age"); // Sort ascending result.sort("age", RealmResults.SORT_ORDER_DESCENDING);() Asynchronous Queries Queries can be performed on a background thread. Most queries in Realm are fast enough to be run synchronously - even on the UI thread. However for either very complex queries or queries on large data sets it can be an advantage to run the query on a background thread. Example: finding users with name “John” or “Peter” Create the query RealmResults<User> result = realm.where(User.class) .equalTo("name", "John") .or() .equalTo("name", "Peter") .findAllAsync(); Note that the query is not blocking and immediately returns a RealmResults<User>. This is a promise similar to the concept of Future in standard Java. The query will continue to run in a background thread, and once it completes it will update the returned instance of RealmResults. If you want to be notified when the query completes and the RealmResults is updated, you can register a RealmChangeListener. This listener will be called every time the RealmResults is updated to reflect the latest changes in the Realm (usually after a commit). Register a callback public void onStart() { RealmResults<User> result = realm.where(User.class).findAllAsync(); result.addChangeListener( new RealmChangeListener() { @Override public void onChange() { // called once the query complete and on every update // use the result } }); } Remember to unregister any listeners when exiting an Activity or Fragment to avoid memory leaks. public void onStop () { result.removeChangeListener(callback); // remove a particular listener // or result.removeChangeListeners(); // remove all registered listeners } Check if the query has completed if (result.isLoaded()) { // Results are now available } Calling isLoaded on a RealmResults obtained synchronously will always return true. Force load an asynchronous query Optionally you can wait until the query completes. This will block the current thread, making the query synchronous again (same concept as in Future.get()). result.load() // be careful, this will block the current thread until it returns Non-Looper threads. Realms Realms are our equivalent of a database: they contain different kinds of objects, and map to one file on disk. The Default Realm You may have noticed so far that we have always initialized our realm variable by calling Realm.getInstance(Context context). This static constructor will return a Realm instance for your thread, that maps to a file called default.realm located in Context.getFilesDir(). always possible to obtain the absolute path of a realm by using the realm.getPath() method. It is important to note that Realm instances are thread singletons, meaning that the static constructor will return the same instance for every thread. Configuring a Realm Calling Realm.getInstance(context) makes it easy to get started with Realm. For more fine-grained control, it is possible to create a RealmConfiguration object that controls all aspects of how a Realm is created. // The RealmConfiguration is created using the builder pattern. RealmConfiguration config = new RealmConfiguration.Builder(context) .name("myrealm.realm") .encryptionKey(getKey()) .schemaVersion(42) .setModules(new MySchemaModule()) .migration(new MyMigration()) .build(); // These two are equivalent Realm realm = Realm.getInstance(context); Realm realm = Realm.getInstance(new RealmConfiguration.Builder(context).build()); The RealmConfiguration can be saved as a default configuration. Setting a default configuration in your custom Application class, will ensure that it is available in the rest of your code. public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); RealmConfiguration config = new RealmConfiguration.Builder(context).build(); Realm.setDefaultConfiguration(config); } } public class MyActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Realm realm = Realm.getDefaultInstance(); } } It is also possible to have multiple RealmConfigurations. In this way you can control the version, schema and location of each Realm independently. RealmConfiguration myConfig = new RealmConfiguration.Builder(context) .name("myrealm.realm"). .schemaVersion(2) .setModules(new MyCustomSchema()) .build(); RealmConfiguration otherConfig = new RealmConfiguration.Builder(context) .name("otherrealm.realm") .schemaVersion(5) .setModules(new MyOtherSchema()) .build(); Realm myRealm = Realm.getInstance(myConfig); Realm otherRealm = Realm.getInstance(otherConfig); In-Memory Realm Define an instance for an un-persisted in-memory Realm: RealmConfiguration myConfig = new RealmConfiguration.Builder(context) .name("myrealm.realm") .inMemory() .build(); Setting this will create an in-memory Realm instead of saving it to disk. In-memory Realms might still use disk space if memory is running low, but all files created by an in-memory Realm will be deleted when the Realm is closed. Please note that creating an in-memory Realm with the same name as a regular (persisted) Realm is not allowed. When all in-memory Realm instances with a particular name go out of scope with no references, all data is freed for that Realm. It is recommended that you hold onto a reference to any created in-memory Realms for the duration of your App. Using a Realm across Threads The only rule to using Realm across threads is to remember that Realm, RealmObject or RealmResults instances cannot be passed across threads. However, you can use an asynchronous query or asynchrounous. Finding a Realm File If you need help finding your app’s Realm file, check this StackOverflow answer for detailed instructions. Schemas The default schema for a Realm is defined as all the Realm model classes in a project. It is possible to change this behavior, e.g. if you want to restrict a Realm to only contain a subset of classes. This is done by creating a custom RealmModule. // Create the module @RealmModule(classes = { Person.class, Dog.class }) public class MyModule { } // Set the module in the RealmConfiguration to allow only classes defined by the module. RealmConfiguration config = new RealmConfiguration.Builder(context) .setModules(new MyModule()) .build(); // It is possible to combine multiple modules to one schema. RealmConfiguration config = new RealmConfiguration.Builder(context) .setModules(new MyModule(), new MyOtherModule()) .build(); Sharing schemas For library developers: Libraries that include Realm must expose and use their schema through a RealmModule. Doing so prevents the default RealmModule from being generated for the library project, which would otherwise conflict with the default RealmModule being generated by the app. The library’s RealmModule is also how the library exposes its Realm classes to the app. //(context) .name("library.realm") .setModules(new MyLibraryModule()) .build(); // Apps can add the library RealmModule to their own schema. RealmConfiguration config = new RealmConfiguration.Builder(context) .name("app.realm") .setModules(Realm.getDefaultModule(), new MyLibraryModule()) .build(); See a complete example of how RealmModules work between library and app projects here. Setting the RealmObject field to null will clear the reference but the object will not be deleted from the Realm.. Setting the value to null for a RealmList field will clear the list. That is, the list will be empty (length zero), but no objects have been deleted. The getter for a RealmList will never return null. The returned object is always a list but the length might be zero.. Moreover, each condition in a link query is evaluated separately. The final result is the intersection of the results of the link queries. This implies that the following query will give you all contacts with at least one active and at least one inactive email addresses: RealmResults<Contact> contacts = realm.where(Contact.class).equalTo("emails.active", true).equalTo("emails.active", false).findAll();(); } Parsing JSON with Realm is subject to the following rules. - Creating object with JSON which has the field with a null value: - For a not-required field, set it to nullwhich is the default value. - For a required field, throw an exception. - Updating object with JSON which has the field with a nullvalue: - For a not-required field, set it to null. - For a required field, throw an exception. - JSON doesn’t have the field: - Leave the value unchanged for both required and not-required fields. Notifications Since 0.80.3, the RealmChangeListener is managed as a weak reference internally to avoid potential leaks. So DO NOT use anonymous RealmChangeListener when calling addListener. Instead, always maintain the reference to your listeners until you don’t need them anymore. If you have a background thread adding data to a Realm, your UI or other threads can get notified of changes in a realm by adding a listener, which is executed when the Realm is changed (by another thread or process): public class MyActivity extends Activity { private Realm realm; // A reference to RealmChangeListener needs to be held to avoid being // removed by the garbage collector. private RealmChangeListener realmListener; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); realm = Realm.getDefaultInstance(); reamlListener = new RealmChangeListener() { @Override public void onChange() { // ... do something with the updates (UI, etc.) ... %>; realm.addChangeListener(realmListener); } @Override protected void onDestroy() { super.onDestroy(); // Remove the listener. realm.removeChangeListener(realmListener); // Close the realm instance. realm.close(); } } models (i.e. your database schema) database schema. But if you do, there will be a mismatch between what Realm sees defined in code & the data Realm sees on disk, so an exception will be thrown. We provide built-in methods so you can upgrade your schema on disk, and the data you stored for previous versions of the schema. See our migrationSample app for details. If there is no file on disk when Realm launches, no migration is needed, and Realm will just create a new .realm file & schema based on the latest models defined in your code. This means that if you are in the middle of development and changing your schema very often, and you are OK with losing all your data, you can delete your .realm file on disk (and the entire dataset it contained!) instead of having to write a migration. This can be helpful when tinkering with models early in the development cycle of your app. Encryption Please take note of the Export Compliance section of our LICENSE, as it places restrictions against the usage of Realm if you are located in countries with an export restriction or embargo from the United States. The Realm file can be stored encrypted on disk by passing a 512-bit encryption key to Realm.getInstance(): byte[] key = new byte[64]; new SecureRandom().nextBytes(key); Realm realm = Realm.getInstance; } } Other libraries This section describes how you can integrate Realm with other commonly used libraries for Android. GSON GSON is a library created by Google for deserializing and serializing JSON. When using Realm with GSON 2.3.1 (latest version), you have to specify an ExclusionStrategy. // Using the User class public class User extends RealmObject { private String name; private String email; // getters and setters left out ... }. Otto Otto is an event bus from Square. Otto works with Realm out of the box, but there are some timing and thread issues to be aware of. Otto normally receives an event on the same thread it was sent. This means that it is possible to add a RealmObject to an event and read its data in the receiver method without any problems. However if you are using the hack described here to always post on the main thread, you cannot have RealmObjects as part of your event data unless you always send events from the UI thread also. This is normally done to be able to manipulate UI elements in response to an event which is only possible from the main thread. When a RealmObject is changed in one thread, Realm schedules a refresh of Realm data on other threads using a Handler. Otto.post(event) on the other hand, dispatch events immediately. So if you post an event to another thread to notify about changes to Realm data, you will have to manually call realm.refresh() to get the latest data. @Subscribe public void handleEvent(OttoEvent event) { realm.refresh(); // Continue working with Realm data loaded in this thread }. 1) If your model contains a RealmList you need to register a special adapter and 2) Once an object has been parcelled, it becomes detached from Realm and at this point behaves like a standalone object containing a snapshot of the data. Further changes to this object will not be persisted in Realm. Retrofit Retrofit is a library from Square that makes it easy to work with a REST API in a typesafe manner. As Retrofit uses GSON internally, it also needs a properly configured GsonConverter if you want to deserialize network JSON data to RealmObjects.(); // Configure Retrofit to use the proper GSON converter RestAdapter restAdapter = new RestAdapter.Builder() .setEndpoint("") .setConverter(new GsonConverter(gson)) .build(); GitHubService service = restAdapter.create(GitHubService.class); Retrofit does not automatically add objects to Realm, instead you must manually add them using the realm.copyToRealm() or realm.copyToRealmOrUpdate() method.: Next Steps Take a look at our examples to see Realm used in practice in an app. Happy hacking! You can always talk to a live human developer on realm-java.: - The upper limit of class names is 57 characters. Realm for Android prepend class_to all names, and the browser will show it as part of the name. - The length of field names has a upper limit of 63 character. - The dates are truncated with a precision of one second. - Nested transactions are not supported, and an exception is throw if it is detected. - Strings and byte arrays ( byte[]) cannot be larger than 16 MB. - Case insensitive string matches in queries are only supported for character sets in ‘Latin Basic’, ‘Latin Supplement’, ‘Latin Extended A’, ‘Latin Extended B’ (UTF-8 range 0-591). Objects Due to how the proxy classes override getters and setters in the model classes there are some restrictions to what is allowed in a model class: - Only private instance fields. - Only default getter and setter methods. - Static fields, both public and private. - Static methods. - Implementing interfaces with no methods. This means that it is currently not possible to extend anything else than RealmObject or to override methods like toString() or equals(). Also it is only possible to implement interfaces. We are working on lifting these restrictions. Sorting Sorting is currently limited to character sets in ‘Latin Basic’, ‘Latin Supplement’, ‘Latin Extended A’, ‘Latin Extended B’ (UTF-8 range 0-591). For other charsets, sorting will not change the RealmResults object. Case insensitive queries Setting the caseSensitive flag when using equalTo, contain, endsWith or beginsWith will only work on characters from the English locale. Read more about these limitations here. Threads Although Realm files can be accessed by multiple threads concurrently, you cannot hand over Realms, Realm objects, queries, and results between threads. The thread example shows how to use Realm in a multithreading environment. Migration The migration support has not matured yet, and you have to rely on a number of internal classes. We plan to have easy-to-use migration support in the future but currently the best option is to look at the migration example. Realm files cannot be accessed by concurrent processes Although Realm files can be accessed by multiple threads concurrently, they can only be accessed by a single process at a time. Different processes should either copy Realm files or create their own. Multi-process support is coming soon. How can find and view the content of my Realm file(s)? This SO question describes where to find your Realm file. You can then view the content with our Realm Studio. How big is the Realm a “core” in the code, what is that? The core or Realm Core is our AP. A consequence of proxy classes overriding setters and getters is that you cannot create customised versions of setters and getters. A workaround is to use an ignored field (the @Ignore annotation), and use its setter and getter to add your customisation to. A model class found look like: package io.realm.entities; import io.realm.RealmObject; import io.realm.annotations.Ignore; public class StringOnly extends RealmObject { private String name; @Ignore private String kingName; // custom setter public void setKingName(String kingName) { setName("King " + kingName); } // custom getter public String getKingName() { return getName(); } // setter and getter for 'name' } You can then use the setKingName() as a custom setter instead of setName(). Please note that the custom setter uses setName() and does not assign directly to the field.. What to do about out-of-memory exceptions? Realm for Android is built upon an embedded storage engine. The storage engine does not allocate memory on the JVM heap but in ‘native’ memory. When the storage engine cannot allocate ‘native’ memory or the file system is full, Realm will throw an io.realm.internal.OutOfMemoryError exception, and your app has run out of memory. It is important not to ignore this exception by having an empty catch block or a too broad catch. If your app does continue running, acessing the Realm file might leave your Realm file in a corrupted or inconsistent state. In the case of io.realm.internal.OutOfMemoryError,File.) What does the exception ‘Annotation processor may not have been executed.’ mean? During compilation of your app, the model classes are processed and proxy classes are generated. If this annotation process fails, the proxy classes or their methods cannot be found. When your app begins running, it Realm will throw exception with message ‘Annotation processor may not have been executed.’. You may see this in case you use Java 6 as it doesn’t support inheriting annotations. You then have to add @RealmClass before your models. Otherwise it can often be solved by removing/cleaning all generated or intermediate files and rebuild. Android Chromium WebView Note: This bug has been fixed with v43 of the WebView. Starting with 5.0 Lollipop, Android began shipping a Chromium WebView that can be installed and updated through the Play Store. Unfortunately there is a bug in the latest version of this webview (v40), that can cause encrypted Realms to crash if used together. The current work around is to either downgrade the WebView to v39, or to make sure to call CookieManager.getInstance() before opening the encrypted Realm. @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_webview); CookieManager.getInstance(); // Prevent Realm from crashing Realm realm = Realm.getInstance(this, getKey()) } Details can be found here Encryption is not supported on this device Exception A few older devices (HTC One X for example) does not work correctly with signal handlers. Realm encryption currently relies on the signal handler which means encryption of Realm doesn’t work on those devices. The same problem on HTC One X happened to Firefox for Android as well. See On-demand decompression startup failure with Firefox on the HTC One X (Android 4.2.2) for more details. From v0.82.2 Realm tries to detect if the device has this problem when the encrypted Realm is opened, and throws a RealmEncryptionNotSupportedException on those devices. Please consider catching the RealmEncryptionNotSupportedException and use Realm without encryption on those devices instead for now. We are working on an alternative solution for encryption which will support those devices as well in the future. I see a network call to Mixpanel when I run my app, what is that? Realm collects anonymous analytics when you run the Realm annotation processor on your source code. source code is annotated.+.	https://realm.io/docs/java/0.84.1/	CC-MAIN-2018-51	refinedweb	4,953	57.16

The of the master bedroom into the next available room, which is my office, and because the dog is intensely curious about the carpet layers, and at least one of the carpet layers is terrified of the dog, and the dog gets neurotic if left alone behind a closed door, I need to be in a room with a door I can close while the carpet dudes do their work. Thus: Daughter’s room. Said daughter is out of the house until this afternoon, which helps. On the other hand, the carpet in here in new, and I think I may be getting a contact high on the venting plastic gases. I may have to crack open a window. Also, Edward from Twilight is staring down at me moodily from above my daughter’s desk, which is unsettling. The interests of an eleven-year-old girl are really not my own, I have to say. Anyway, exiled as I am in a pink-purple, carpet-fumed room with a large neurotic dog while people pound away at the floor just down the hall, I’m expecting not to get a whole lot done today. Time for a good book, of which, fortunately, I have several. 41 thoughts on “In Exile” But…you have EDWARD to keep you company. Is he sparkling? I predict some weird dreams for you tonight. It’s so… PURPLE I’d be so tempted to draw a Sharpie marker mustache on Edward. “But honey, the fumes told me to… Kodi was there, he’ll tell you…” Good book, eh? Does that mean it’s time to RELEASE THE KRAKEN? It’s not gonna release itself, you know. I actually like the color on the walls although it seems a bit dark. I would have chosen something a little lighter. In a slightly related note, it seems the actor who played Jacob in the Twilight movies will be in Pittsburgh to film a movie in July. I’m hoping that I don’t have to be anywhere near where he is filming. If you’re feeling a contact high, imagine what the puppy is going through. My god, it’s full of purple! That is a good size book collection for a little girl. I think that shot was staged. There’s no way an eleven year old’s room is that clean. Terrified of the dog? But Kodi’s such a cute widdle puppy! @Joe M, #9: Heck, even _my_ room isn’t that clean. Wow, what a perfect room for an 11 year old. Isn’t amazing how very noisy carpet laying is? And how long it takes, too. You did tell the carpet layer that Kodi isn’t really an anteater, didn’t you? And that Kodi is just as scared of the carpet layers as they are leery of him. Anyway, crack open a window, ignore Edward, and have a semi-productive day. Count your blessings. Athena could be part of Team Jacob instead. I like seeing full bookshelves in any youngster’s room. It’s a good thing. Oh, that kind of lavender. (Understands facebook post now.) It’s nice that you’ll let the fair Athena pick her room colors. My parents let us do that too as long as the color was off-white. Joe M. @ 9: If one of my parents needed to temporarily use my room for an office when I was eleven, my room would have been spotless. (Also, while I’m generally a bit of a slob, my younger brother never has been. His room would’ve looked almost that clean most days.) Having to look at a big poster of Edward? Don’t they make the inmates at Gitmo do that? That should be classified as Cruel and Unusual Punishment!! I like the colors of Athena’s room. Edward? Oh god no. Well at least you have a dog and a book. =) “I predict some weird dreams for you tonight.” – #1 If you do have dreams about Edward, you have to tell us about them. The dog seems to be taking it all in stride… I saw a poster pic on Reddit requesting Buffy’s return (to kill Edward of course). Made me laugh. Apparently there is also a Youtube of Buffy vs. Edward, but I haven’t seen that one yet. I should send in a good picture of our dog soon – we have a giant schnauzer who LOVES sleeping on my bed. But only when I’m also sleeping on it. Most likely the adhesives. Shoulda requested low VOC adhesives. That stuff will be leeching out at you for years. Sorry dude. Seriously, do open an window. It truly is toxic. I had every single window open in my house when we recarpeted the upstairs. It really didn’t take that long to go away. Carpet is so much better than it used to be. Poor doggie. Poor writer. All that purple. The schnauzer: an object case in how we rearrange reality to suit ourselves. Our schnauzer is not miniature; yours is giant! (The “giant” schnauzer used to be simply the schnauzer; the current schnauzer used to be the miniature and the current miniature used to be the toy. Soon they’ll have a toy the size of a shrew. Then the schnauzer will be the giant schnauzer and the giant schnauzer will be the dino-schnauzer.) When will you tape a whole pheasant to Codi and get rid of that silly cat meme? That’s what the (giant) people want. On cleanliness: when I was eleven, my room was that neat. Most of the time. Also, I would have been salivating over the bookshelves. I had that many books, but not that much space to keep them. (And it looks like she, like me, does not have enough room on the shelf for all of them!) I miss my books. It simply wouldn’t be practical to bring them all to college. They wouldn’t all fit in my room, never mind shelves. Oh . . . and TomG: Buffy v. Edward: Awww. Kodi just clearly wants to be friends. Preteen girls unite! That appears to be pretty near the exact shade of carpeting I asked for and got in my room when I was ten. No lavender paint on the walls, but we did put up wallpaper with purple flowers all over it. And these windowshades with giant bunches of African violets. My parents were pretty indulgent, I must say. I love Athena’s room! I would have loved that carpet in my room when I was her age. Heck, I wouldn’t mind it now! Have a great time relaxing with the dog and your book. #26 Brynne, thanks! I needed that! Looks like Diary of a Wimpy Kid: The Last Straw is in the top of that pile of books on the floor. Are Akitas ever NOT neurotic? If I wear a different hair style or hat, mine gives me a wary look. Mine seems to watch (always facing the door) and be hyper sensitive about anything different, which makes her very good at what she does (protect, guard, and alarm). the dog is intensely curious about the carpet layers, and at least one of the carpet layers is terrified of the dog My brain insists on reading ‘carpet layers’ as in ‘layer cake’ as in ‘differentiated strata of the carpet’ — possibly the carpet and the carpet pad. This creates a subsequent image of either the carpet itself, or the carpet pad, being terrified of the dog. Poor carpet pad. @31 You beat me to that comment by about 5 minutes. I did the same thing. When I read that Edward from Twilight was staring down at you, for one brief moment (before I read on) I thought that perhaps the fumes HAD gotten to you…although if that were the case, perhaps Athena would be happier to keep the fumes… I’m skeptical about the dog’s neuroses. In every photo that -I- have ever seen of this dog, it appears to be unconscious. Meanwhile–just wanted to say, I got my copy of YYOUR HATE MAIL WILL BE GRADED YESTERDAY, and crawled into bed in a state of exhaustion last night (trying to finish overdue book that frantic editor is asking after daily), and thought I’d barely have the concentration or energy to get through a couple of essays before falling asleep. Fifteen compulsively-read essays later, I was appalled to realize how much much-needed sleep I would lose, thanks to you. Damn you, sir! that room is so full of win. :) your daughter just gets cooler and cooler. Oh Carpet High.. how I love thee. My grandfather has been a Flooring Installer (not Carpet Layer, bah!) for 44 years, and needless to say I’ve helped him with a lot of jobs since I was a little kid. Haven’t done it in a while with him, but every time I smell new carpet somewhere it gets me all excited. Feels good to remember childhood. Oh… oh god. I’ve been on the internet too log. I saw that photo and my first thought was “Looks ‘shopped.” commits seppuku and dies with honor Condolences on having to play musical rooms — it’s been decades since I did that, but then I was doing the decorating (in that “copious spare time” we all know & love), so it lasted longer and was more traumatic. Did Athena get her purple room before or after the kid in the Home Depot ad? and does she want to dye her hair purple too? It’s coming, you know. I had an 18 year old blonde daughter who is now a 19 year old redhead. Sounds like a certain young lady needs to be reminded: “Real vampires DIE in sunlight.” I love the paint. I hate white rooms.	http://whatever.scalzi.com/2010/03/31/in-exile/	CC-MAIN-2017-09	refinedweb	1,655	84.27
Hi, I`ve started writing an annotation based couchdb Document Object Mapper called jBeanbag. The approach I`ve taken is to use 100% annotations so the users domain model does not have to derive from the api. I`m also trying to make it CouchDB focused rather then JSON focused which a few of the other apis seem to be. The aim is to enable easy mapping to and from CouchDB documents to Java classes and also provide some infrastructure support for example @Linked annotation could be above a field meaning the field should be a linked document and handling conflicts by returning Java objects of the different versions in an exception. I`d also like to put in more annotations for other kinds of relationships like bi-directional. An example Java annotated class is at the bottom of this mail. I`m using the ASM library to create a Meta model of the Java classes ,including all the CouchDB configuration for that class, is then cached in ehcache and can be reused for serializing to/from the JSON. The JSON parsing I`m using the the Jackson JSON Streaming/Mapping apis. ASM helps by making it easy to analyze the class structure in advance ,using its visitor pattern, as well as giving access to Generics information. So I`m looking to the community for any CouchDB patterns they keep repeating in code which could be included in the framework as well as anyone else who could be interested in contributing to the code base. Going forward I`d also like to provide wrappers for Groovy to make it a bit more ,well Groovier and Scala wrappers. At the moment theres not a released version but I`m hoping to have a 0.01 version soon. But I have done most of the simple conversion to/from JSON for primitives,arrays,maps,lists, sets,Objects, Wrapper Objects e.g Integer class,enums and Dates. Currently it`ll struggle with things like Arrays of Maps or Lists of Lists but that should be fixed soon. I`m currently working on the HTTP client side of things. Thoughts,comments and especially help all appreciated. regards Darran @Document(location="people") public class Person{ @Id private String id; @Revision private String revision //Will be a list of embedded pet objects in the person document //not really needed as embedded is the default @Embedded @NotNullable private List<Pet> pets; //List will be parsed and written as linked documents to this class @Linked private List<Car> cars; private String name;//Will be written as name:<value> in document @Ignore private String dontWriteToDocument; //Won`t be written to the document ......	http://mail-archives.apache.org/mod_mbox/couchdb-user/201004.mbox/%3Cm2jeba3d3df1004130018kb8267b2cxca90e8ec509efcfa@mail.gmail.com%3E	CC-MAIN-2015-48	refinedweb	443	57.91

Same problem here. After 6-7 hours of working, DHT11 sensor stops. Then I reboot and again it is working some time and then again goes in offline mode. I seem to be having a similar issue. I will test and see if I can find the problem. @doerek @ognqn.chikov are you able to run the python script in the terminal to see if you get any errors? Hello,I was run the python script in terminal and more than 10 hours it is working. I will wait 10 more hours to confirm that it is working without issues. Same issue with termination after some hours.. I believe the problem is related the the growing memory bug here Hopefully there is a fix pushed sooner rather than later. If the memory fix does not solve the problem I will investigate further. Hi @adamThe last 48h my DHT22 stayed Online. (No changes on my side)Was there a fix? GreetingsDoerek EDIT:Sry, false Alarm ...my browser was loading the Dashboard from cache... Hi @doerek, No changes to the Raspberry Pi agent software just yet, I'll say that's probably just better luck on your side. When we do make a change I'll post it in a pinned thread on this forum. Nevermind...my browser was loading the Dashboard from cache... Thanks very much. I have several issues. When I registered with cayenne , I only filled name surname, password and email. No specific question for username. I was not given the client I'd talked about in the code. How do I resolve these issues. Because I couldn't just continue since I really don't know what specific is required in those spaces. Finally, to get the unique channel talked about in your direction, do you mean I should run this command on my terminal : cd /sys/bus/w1/devices And then copy the unique code? If yes, is it all the code or the first 8 digit. Please, I would appreciate if your directory is a little more detail, many of us here are new bies. Thanks Anticipating your positive reply. Ajiri The username, password, and client ID are all generated when you go to the dashboard and click Add new>Device/widget then click the blue Bring Your Own Thing button. This username/password is not your Cayenne username/password. As far as the channel, you just need to make sure you aren't using the same channel for anything else. Generally I start at 1 and just work my way up. There is no limit in the docs for the channel value so I'm assuming you can pretty much use any number you can think of. Thank you for your code but shouldn't it be: Your code will probably work fine as it is. But my problem was the following:If you send a sensor value first as channel 3, then channel 1 and last channel 2. Then the sensor at channel 2 won't show after a while. This might be a beginners problem (second day here)... Now it works fine:) You are correct, typo on my part. I just fixed it. I didn't loop the sensor with a waittime for 5 sec. Instead I run the script every minute. So if things go south (program error) I'll get another shot (crontab value is set to 1 min).Is it possible to pass some kind of timestamp or avoiding the offline message that I haven't update my sensor since the dinosaurs was walking on earth? Except for the message it works fine! Maybe I will try to do your approach, but instead of running the script everyminute, I will try to send everyminute the real data, and then every other frame to be some fake data stream, zeros or empty stream. What do you think? Please give it a shoot.If I understand you. You should use the 5 second loop, but only the 20th time (5 sec X 20 = 1 min), you'll get sensor data and send it. All other times (19) you just send the last measured data. Its interesting to know if it's the sensor that makes it crash. However my solution works so far, execept for the ugly offline message. I did NOT try it yet, because I have another problem. When I open the device, the measurements looks ok: But after that the measurements are showing: and when I refresh again, they looks normal. Any Ideas?UPDATE: Here is the graphic chart. Sometime it is normal, and most of the time the measurements are unreal: I get the same insane numbers sometimes and also before I started with Cayenne.I believe the problem is the cheap DHT11 sensor (I bought mine from china).If I manufactured a humidity sensor I would put a maximum limit for output to 100%... I've now ordered a DHT22 and I hope to get better result Sorry for my miscalculation before: 5 sec X 20 IS NOT 1 min. I ment 12x5... I try everything, and it seems to work when I test it. Now I just solder the wires and put it on place. I hate the cheap china shits.. I will try in the weekend with the script, no matter what kind of result I get, I will try and post here if I have interesting solution. Thank you!

It seems that the wiki's robots.txt is not very good, because the standard has only the notion of "directories" so we can't effectively block "dumb" crawlers who may not support complex matching like "/index.php?diff=". This may have lead to enabling the Lockdown extension [5][6] which prevents public access to archived pages etc. If we use short URLs, e.g. with "/wiki/" as $wgArticlePath and "/w/" as mw:$wgScriptPath as recommended in Manual:Short URL, robots.txt would be as simple as User-agent: * Disallow: /w/ Disallow: /index.php Disallow: /skins/ But this assumes that MediaWiki is installed to "/w/" rather than the webroot ("/") which is the case now, so it would have to be moved. It would be simpler to keep it in the webroot, keep $wgScriptPath empty ("") and explicitly allow the path for $wgArticlePath: User-agent: * Allow: /wiki/ Disallow: / Note that the Allow directive is non-standard, but bots who don't support it would be simply unlucky :-) So, the main question is what do we use as the $wgArticlePath?

Hi; i want to change page size in my project. Instead of A4 i want to use A3 and my specific sizes. i search and find some topics about it but they said only "you can not change the paper size". is there anyway to do this? only this problem i have to move my project to java. thanks and regards umuthan You could use flash.printing.printJob.supportsPageSetupDialog to display the operating system's Page Setup dialog if the current environment supports it. Use the supportsPageSetupDialog property to use A3 size.

Solve Word Break Problem using Backtracking in Python In this tutorial, we are going to solve the Word Break Problem using Backtracking and the programming language we’re using is Python. Here the problem is that we are given a long string of words without any spaces and a dictionary of words with the help of Python programming. We are supposed to break the string or sentence into the possible words present in the dictionary. Using backtracking to solve the problem The idea is that we will select a word from the dictionary and search for that word in the string, if any substring matches with the word then we print it otherwise we move ahead and search for the next word in the dictionary. For every word selected we search for the first letter of the word in the string, if it is present then we move to the next letter of the word and so on. We will keep two pointers namely “i” and “j” to keep track of the letters in the word and the string respectively that we have already seen. Now we will go through the string only once for every word in the dictionary by incrementing the pointer “j”. But we will keep backtracking through the word that has been selected, with the help of the pointer “i”. Once the first letter of the word is found we will increment “i” till there is a mismatch, in that case, we will set back the value of “i” to 0, and again start searching for the first letter in the rest of the string. Implementation of the solution In this example is the string we have taken is string="iwantindependence" And the dictionary is word_dict={0: 'i', 1:"like", 2:"ali",3: "want",4: "pancake",5: "mobile",6: "independence", 7: "tin" ,8: "icecream",9: "ant", 10:"pen",11: "fNow Now we will create a function ” break_string” which will take the word and the string and print the word if it is present in the string. Below is our Python code: def break_string(word,string): # initiliasing pointer pointing to the string to 0 j=0 while(j<len(string)): # initialising pointer pointing to the word to 0 i=0 while(i<len(word)): if word[i]==string[j]: # if i==length of word, then the word selected has been seen till the end # hence the word matched with the substring if(i==(len(word)-1)): print(word) break # otherwise we will carry on the search else: i+=1 j+=1 # if letters or alphabets don't match else: # and string is seen till the end --> break if(j==len(string)-1): break else: # keep increamenting the string i=0 j+=1 # Once the word is found --> stop incrementing the string break Once we get a letter match we increment both “i” and “j” and continue. If after matching some letters of the word and the rest of the letters don’t match then we come out of the second while loop and put the pointer of the word back to 0. In case the letters are not matching we keep the pointer of the word “i” =0 only and keep incrementing the pointer “j” of the string. Pointer “i” is only incremented in case of a match, otherwise is always kept at the start of the word(i=0), while pointer “j” keeps moving ahead. When “i” is equal to the length of the word, we have matched the entire word, hence the word is found. We print it and come out of the loop. To call the function we give the string and the words by iterating through the dictionary. for word in word_dict.values(): break_string(word,string) The output is i want independence tin ant pen	https://www.codespeedy.com/solve-word-break-problem-using-backtracking-in-python/	CC-MAIN-2021-10	refinedweb	632	65.59

Sizes You can set the width and height of widgets in guizero. Widgets are sized by either pixels or characters depending on the widget and what it contains. Some widgets size can also be set to "fill" where it will use up all of the available space. from guizero import App, PushButton, Slider, ListBox app = App() # A PushButton's size is noted in characters button = PushButton(app, width=30, height=5) # A Slider's size is noted in pixels slider = Slider(app, width=300, height=30) # Some widgets such as ListBox can also be told to fill all the available space listbox = ListBox(app, width="fill", height="fill") app.display()	https://lawsie.github.io/guizero/size/	CC-MAIN-2019-30	refinedweb	110	55.07

This is one of the frequent requirement in visual studio either adding new namespaces corresponding to a class or resolving the namespaces. If you are adding a new class in your code then you may need to add the correspondence namespaces. To do it, you may either manually type the Using Namespace or you just right click on the class name and select Resolve > Namespace. But using “Ctrl+.” you can automatically add the namespace in your code. Lets consider you want to add DataTable in your code, so for that you right click on that class and select resolve to resolve the namespace. Using “Ctrl+.” you can also automatically add the using statement as shown in below Fig : Add namespace using Shortcut key Pingback: Dew Drop – January 26, 2011 \| Alvin Ashcraft's Morning Dew	https://dailydotnettips.com/adding-and-resolving-namespaces-using-shortcut-key-in-visual-studio/	CC-MAIN-2018-30	refinedweb	134	69.11
Hello World from Boost::Python12 Oct 2005 I just created a “Hello World” application in Boost::Python. I’m comparing the Boost and SWIG options for embedding Python and making PN code available to it so this is the first step for the Boost implementation. Here’s the code: #include <boost /python.hpp> int main(int argc, char* argv[]) { Py_Initialize(); object main_module(( handle<>(borrowed(PyImport_AddModule("__main__"))) )); object main_namespace = main_module.attr("__dict__"); // Run some python! handle<> ignored((PyRun_String( "print \"Hello World from Python!\"" , Py_file_input , main_namespace.ptr() , main_namespace.ptr()) )); Py_Finalize(); return 0; } Not very much code at all to get going! boost_python.dll (required to use Boost::Python) comes in at 180kb. The initial test app (as coded above) in Release configuration takes 40kb. The differences between this and the SWIG embedding version will be minimal, boost doesn’t hide much of the embedding code for you. The real differences will be in creating wrappers for functions and classes. With boost I have to write wrappers, SWIG will automatically generate them. The interesting bit will be the size of the code created.	http://untidy.net/blog/2005/10/12/hello-world-from-boostpython/	CC-MAIN-2019-47	refinedweb	180	58.79

These are chat archives for Nethereum/Nethereum var electionType = await contract.GetFunction("electionType").CallAsync<string>().Result I get the same errors if I run npm run compile from the root folder. As stated I am no great expert in this, but Juan has taken me through it once before so something might come back to me. Are you able to start a debugging session in visual studio code? I run "Launch Extension" which is configured in the .vscode folder. I am guessing there's path magic required for the compilation to work. @Nufflee - well npm run compile now works for me. I had to change a few typescript files in the node_modules\nethereum-codegen to fix the namespace issue. It's a workaround, like I said, these typescript files are code generated, so I haven't fixed the core issue yet. I'll need to discuss this with Juan when he returns - I'd imagine what we're doing here may not actually be necessary. But it may unblock you for the time being. To get you going - you could download the nethereum-codegen folder below and replace your current folder (within ./node_modules).

FileInfo Class Provides instance methods for the creation, copying, deletion, moving, and opening of files, and aids in the creation of FileStream objects. For a list of all members of this type, see FileInfo Members.

Any instance members are not guaranteed to be thread safe. Remarks Use the FileInfo class for typical operations such as copying, moving, renaming, creating, opening, deleting, and appending to files. Many of the FileInfo methods return other I/O types when you create or open files. You can use these other types to futher. .NET Compact Framework Platform Note: The .NET Compact Framework does not support getting or setting directory attributes.

Forking a project is, in most cases, a two-step process. On the project’s home page, in the top right, click the Fork button. Click a namespace to fork to. Only namespaces you have Developer and higher permissions for are shown.Note: The project path must be unique within the namespace. The fork is created. The permissions you have in the namespace are the permissions you will have in the fork. Repository click Submit merge request to conclude the process. When successfully merged, your changes are added to the repository and branch you’re merging into. Removing a fork relationship You can unlink your fork from its upstream project in the advanced settings.	https://docs.gitlab.com/ee/user/project/repository/forking_workflow.html	CC-MAIN-2020-50	refinedweb	114	77.23
Zero. First we need to load the petlib Elliptic Curve module petlib.ec and the genzkp functions used to define and verify proofs. We then define an EC group G, and its order. As it happens group 713 is OpenSSL’s “NIST/SECG curve over a 224 bit prime field“. from petlib.ec import EcGroup from genzkp import ZKProof, ZKEnv, ConstGen, Sec # Define an EC group G = EcGroup(713) print (EcGroup.list_curves()[713]) order = G.order() Next we need to define the proof statement using an instance of ZKProof, namely zk. The proof variables and constants are defined using zk.get() (or zk.get_list()). This function takes the type of variables defines, either a constant generator ConstGen, a secret Sec or a generator Gen that is used internally by the proof. It also takes the names of the variables, as they are going to be used later to bind values to them during the construction and verification of the proof. After defining all variables one or more linear statements can be associated with the proof, such as Cxo = xg+oh, using the add_proof method. ## Define the Zero-Knowledge proof statement zk = ZKProof(G) g, h = zk.get(ConstGen, ["g", "h"]) x, o = zk.get(Sec, ["x", "o"]) Cxo = zk.get(ConstGen, "Cxo") zk.add_proof(Cxo, xg + oh) For debugging or other visualization purposes the proof statement can be printed out in Latex using the render_proof_statement method. When compiled in a Latex document this renders to: ## Render the proof statement in Latex print(zk.render_proof_statement()) Using standard petlib math function, we can build a concrete Pedersen commitment using random h, x an o, an define Cxo = xg+oh. # A concrete Pedersen commitment ec_g = G.generator() ec_h = order.random() * ec_g bn_x = order.random() bn_o = order.random() ec_Cxo = bn_x * ec_g + bn_o * ec_h The concrete secrets, EC points and commitment then need to be bound to the variables of the zero-knowledge proof. We can do this by defining an environment, using ZKEnv, and binding the values to the proof variable names. For example, env.x = bn_x binds the value bn_x to the proof variable x. Since we are first to prove the statement, all secrets need to be defined. ## Bind the concrete variables to the Proof env = ZKEnv(zk) env.g, env.h = ec_g, ec_h env.Cxo = ec_Cxo env.x = bn_x env.o = bn_o Finally, on the prover size, we construct the signature (or NIZK) using the build_proof function. This can be serialized and deserialized using the petlib.pack functions if necessary. # Create the Non-Interactive Zero-Knowledge (NIZK) proof sig = zk.build_proof(env.get()) On the verification side, the exact same statement needs to be defines, as zk. An environment is then created binding values to all public variables (g, h and Cxo), but not to the secrets. # Execute the verification on the proof 'sig' env = ZKEnv(zk) env.g, env.h = ec_g, ec_h env.Cxo = ec_Cxo The verification is then performed to ensure the signature and the environment may be used to verify the statement of the NIZK. assert zk.verify_proof(env.get(), sig) The genzkp library has been used to implement all proofs of the examples/amacscreds.py anonymous credential system. The proofs of these scheme are elaborate and illustrate how to define lists of secrets or lists of public generators, parametrically. The full source code of the running example is also available.	https://conspicuouschatter.wordpress.com/2016/01/23/zero-knowledge-proofs-library-in-petlib/	CC-MAIN-2019-35	refinedweb	569	68.36

As a dad of 2 young kids, a non-trivial portion of my day is devoted to poop. Lots and lots of poop. When my oldest began potty training, they would wake up in the middle of the night needing to use the bathroom. And while toddlers’ lungs make a great alarm, we needed to find a solution that wouldn’t disturb the younger one sleeping 10 feet away. I’m always on the lookout for how I can win my kids’ cooperation in novel and fun ways. Bonus points if it involves getting to tinker on an engineering project myself. Enter the Poop Button.. Before we start: IoT poop button prerequisites Let’s walk through setting one up – here’s what you’ll need to build your very own poop button. Buy a AWS IoT Button The hardware behind the IoT Poop Button is the 2nd Generation AWS IoT Button. You can purchase your own through this link. Set up a local dev environment To write the code for the Lambda, you’ll need a computer with Python 3.6 installed. If you’re on a Mac that came with Python 2, I recommend installing 3.6 via Homebrew: brew install python If you have Python 2 installed as well, make sure nothing on your PYTHONPATH points to your Python 2 packages: if [ $(echo $PYTHONPATH \| grep python2) ]; then export PYTHONPATH=; fi If you don’t have an account already, sign up for Twilio. After you’ve signed up, buy a number. Make a note of the phone number you’ve bought, your Account SID, and your Auth Token. You’ll need them all later. Now, go to the list of Verified Caller IDs and make sure the number you want the poop button to call is listed. If not, add it. Sign up for AWS if you haven’t already. Note, an AWS account is not the same as an Amazon account, so even if you have an Amazon account already, you’ll need a separate AWS account. Make a phone call with Twilio in Python All set? Ok, time to get down to the code! Project directory and dependencies Because Lambdas have no way to manage code dependencies, we have to vendor all of our dependencies into our project directly. Then once everything’s ready, we create a zip file that we can upload to AWS when configuring our Lambda function. For this function, our only Python dependency is Twilio’s client library. Let’s configure our project directory and install it: mkdir twilio_poop_button cd twilio_poop_button printf "[install]nprefix=" > setup.cfg pip3 install twilio --target . You should now see a bunch of subdirectories and Python files in your project directory. Remember, twilio has its own dependencies, so don’t be surprised to see things like requests and pytz. (The setup.cfg bit is only required if you installed python 3 via Homebrew. It circumvents a nasty bug in Homebrew’s python.) Python phone call source code Now, create a file called index.py and paste this code into it: import os from urllib.parse import urlencode from twilio.rest import Client def handler(event, context): client = Client( os.environ['TWILIO_ACCOUNT'], os.environ['TWILIO_TOKEN'], ) call = client.calls.create( to=os.environ['ALERT_PHONE'], from_=os.environ['TWILIO_PHONE'], url='?{}'.format(urlencode({ 'Message[0]': "Baby needs to go potty", })), ) print(call.sid) The astute reader will notice 4 variables taken from the environment: - TWILIO_ACCOUNT: The Account SID you copied from your Twilio account dashboard - TWILIO_TOKEN: The Auth Token you copied from the same place - TWILIO_PHONE: The phone number you purchased (In E.164 Format) - ALERT_PHONE: The phone number you want the button to call (Also in E.164 format) The script instantiates a Twilio client and creates a new call using these environment variables. For the content of the call, we’re using a Simple Message Twimlet, a URL that takes a list of messages in its query string and returns a TwiML document. Twilio reads that document and generates a voice message from it. Try out a phone call with Python and the Twimlet Let’s give our code a shot locally to make sure it’s working. Remember to substitute the fake values below with your real ones: TWILIO_ACCOUNT=xxxx TWILIO_TOKEN=xxxx ALERT_PHONE= 15017122661 TWILIO_PHONE= 15555555555 python3 -c 'import index; index.handler(None, None)' Did your phone ring? If not, double check that the environment variables are correct and take a look at your Twilio phone number’s call logs to see if the call showed up. If you’re using a Twilio trial account, make sure the alert phone number is listed in your Verified Caller IDs. If it did congratulations, you have a working Twilio integration! The only remaining step on the code side is to prepare the zip file to upload to AWS: zip -r ~/poop-button.zip . AWS IoT and Lambda integration If you haven’t already, open up your shiny new Amazon IoT button. Take note of the DSN printed on the back. (It probably starts with “G030”.) This is your button’s identifier, and you’ll see the number on a lot of the auto-generated resources AWS creates for you. Set up the button using a native phone app Next, install and launch the AWS IoT Button Dev iOS or Android app to configure your AWS IoT button. I have an iPhone, so the screenshots you see are from the iOS app. Here’s how to connect your button using the app: - Click the button to Set Up AWS IoT Button - Enter the button DSN and give it a name (or, if available, you can scan the box barcode) - Hold the button for 6 seconds until the light starts flashing blue - Tap the “copy password and go to settings” link, connect to the SSID that was displayed in the app, and paste the password it put in your clipboard to connect to the button’s wifi network - Go back to the app. It should recognize that you’re on the button’s wifi and switch to asking you for your home wifi network’s SSID and password. - After that, you’ll set the button’s action. Since we haven’t created our Lambda function yet, let’s start by creating one of their boilerplate functions. Choose “Send Email (python)” and hit “Set action”. - Enter your email address in the box, and you should be all set. Give it a whirl. Push the button. You should see the light blink white and then turn green after the request succeeds. The first time through, you’ll probably get an email from AWS asking you to verify your email. Even that email is proof enough that the button worked, but if you click through the verification link and push the button again you should receive an email with the subject “Hello from your IoT button”. Create a new Lambda function Log into your AWS console and search for the Lambda service. You should see the function we just created in the phone app. Click on the “Create function” button. Choose “Author from scratch”, name your function, choose Python 3.6 as the runtime, and “Create new role from template(s)” for role. Then name your role and choose “AWS IoT Button Permissions” from the Policy templates dropdown. Finally, click “Create function”. A loading indicator will spin for a bit, and then you’ll be taken to your new function. Configure the function’s trigger In the designer, choose AWS IoT from the list of triggers on the left. Below, configure the trigger. Choose “Custom IoT rule” as IoT type and find the rule created when we created our initial function. (You should see the DSN in the rule name.) Make sure “Enable trigger” is checked and click “Add”. Upload the source code archive Back up in the designer, click on the Lambda function and you should see a “Function code” section show up blow the designer. Change “Code entry type” to “Upload a .ZIP file”, make sure the runtime is set to Python 3.6, and enter “index.handler” as the Handler path. Then click the “Upload” button and select the zip file we created earlier. (~/poop-button.zip) Configure environment variables Below the “Function code” section, you should see an “Environment Variables” section. Fill this section out with the same 4 variable names and values we used earlier for local testing. Encrypting the variables with a KMS key is recommended but beyond the scope of this post. Now, save all of your changes by scrolling to the top of the window and clicking the “Save” button. Configure and run a test event At the top of the window, click the “Select a test event” drop-down and choose “Configure test events”. We don’t care about the test input, so the default “Hello world” event will work just fine. Name it and click “Create”. Now click the “Test” button. You should see an execution result. (Hopefully a successful one which includes a phone call.) If your phone didn’t ring, check to make sure the code was actually uploaded and your environment variables are copied correctly using the same values you used to test locally. Try out the button! At this point, you should have a fully configured button. Go ahead and give it a push! Did your phone ring? If not, check to make sure the AWS IoT trigger doesn’t say it needs configuration, its identifier contains the DSN on the back of your button, and it’s enabled. If it rang – congratulations. You have a poop button! You may have noticed that you received both a phone call and an email. IoT buttons can trigger multiple Lambda functions at once. If you’d like to disable the email, either delete the original Lambda function or disable its AWS IoT trigger. Troubleshooting a toddler The great thing about this approach is all of the technology is built and operated by 3rd parties, and pretty reliable ones. In months of daily use, I haven’t yet seen the hardware or software fail. But any parent knows that kids are tough QAers, so let me propose some tips for common failure modes you’re likely to experience. My kid had the button when they went to sleep, but now it’s [lost in the blanket \| tossed across the room \| stuck between the mattress and the bed]. They have to pee and are freaking out because they can’t find it! Adhesive velcro strips work wonders. Stick one to side to the back of the button and the other side to the wall or a part of the bed they’re not likely to knock it off. Make sure it’s close enough to easily reach but far enough away to avoid accidental presses. My kid pushes the button after being in bed for 15 minutes as an excuse to get out of bed. Yeah, mine wised up to this one pretty fast. Now we’re very intentional about giving them multiple chances to go to the bathroom right before bed, but we keep the button with us until they’re asleep. Then one of us sneaks in and puts it in its place. They’ve since learned to use the opportunity to go before bed. My kid refuses to push the button. When we ask them why, they respond “I chose not to.” Believe it or not, we initially had slow button adoption. We normalized button use by requiring our kid to push the button in order to get out of bed in the morning. Of course, this hastened the realization that it was a “get out of bed” pass, which led to the issue above. Poop is as poop does: living with the poop button Our poop button is a life saver. Kid 1 is pretty consistently waking with a dry pull-up, and kid 2 is getting more continuous sleep in the absence of a sibling yelling for Mom and Dad. It’s amazing the difference a small hack can make. On Twitter, I’ve been encouraged to do everything from apply to be on Shark Tank to start a Kickstarter, but I think if anyone is going to make a business out of a button with a poop emoji on it, it’s going to be @internetofshit: I’m sorry yes, where can I order 150,000 of these? — Internet of Shit (@internetofshit) February 26, 2018 As for AWS, whether they’re chagrined or awed at the crappy repurposing of their technology, I think it’s fair to say they didn’t see it coming: 1) create building blocks. 2) let unexpected innovation happen. #AWS /via @dens — Werner Vogels (@Werner) February 24, 2018 For my part, I’ll continue to try to apply practical (ok, and sometimes not so practical) engineering to dad-problems. Whether that’s using Python, Twilio, AWS IoT and Lambda to prevent night-time emergencies or using InfluxDB and a Raspberry Pi to monitor temperature with a Grafana front end I’ve always got multiple projects going.

table of contents NAME¶ tep_print_field, tep_print_fields, tep_print_num_field, tep_print_func_field - Print the field content. SYNOPSIS¶ #include <event-parse.h> #include <trace-seq.h> void tep_print_field(struct trace_seq s, void data, struct tep_format_field field); void tep_print_fields(struct trace_seq s, void data, int size, struct tep_event event); int tep_print_num_field(struct trace_seq s, const char fmt, struct tep_event event, const char name, struct tep_record record, int err); int tep_print_func_field(struct trace_seq s, const char fmt, struct tep_event event, const char name, struct tep_record record, int err); DESCRIPTION¶ These functions print recorded field’s data, according to the field’s type. The tep_print_field() function extracts from the recorded raw data value of the field and prints it into s, according to the field type. The tep_print_fields() prints each field name followed by the record’s field value according to the field’s type: "field1_name=field1_value field2_name=field2_value ..." It iterates all fields of the event, and calls tep_print_field() for each of them. The tep_print_num_field() function prints a numeric field with given format string. A search is performed in the event for a field with name. If such field is found, its value is extracted from the record and is printed in the s, according to the given format string fmt. If the argument err is non-zero, and an error occures - it is printed in the s. The tep_print_func_field() function prints a function field with given format string. A search is performed in the event for a field with name. If such field is found, its value is extracted from the record. The value is assumed to be a function address, and a search is perform to find the name of this function. The function name (if found) and its address are printed in the s, according to the given format string fmt. If the argument err is non-zero, and an error occures - it is printed in s. RETURN VALUE¶ The tep_print_num_field() and tep_print_func_field() functions return 1 on success, -1 in case of an error or 0 if the print buffer s is full. EXAMPLE¶ #include <event-parse.h> #include <trace-seq.h> ... struct tep_handle tep = tep_alloc(); ... struct trace_seq seq; trace_seq_init(&seq); struct tep_event event = tep_find_event_by_name(tep, "timer", "hrtimer_start"); ... void process_record(struct tep_record record) { struct tep_format_field field_pid = tep_find_common_field(event, "common_pid"); trace_seq_reset(&seq); /* Print the value of "common_pid" / tep_print_field(&seq, record->data, field_pid); / Print all fields of the "hrtimer_start" event / tep_print_fields(&seq, record->data, record->size, event); / Print the value of "expires" field with custom format string / tep_print_num_field(&seq, " timer expires in %llu ", event, "expires", record, 0); / Print the address and the name of "function" field with custom format string */ tep_print_func_field(&seq, " timer function is %s ", event, "function", record, 0); } ... FILES¶ event-parse.h Header file to include in order to have access to the library APIs. trace-seq.h Header file to include in order to have access to trace sequences related APIs. Trace sequences are used to allow a function to call several other functions to create a string of data to use.	https://manpages.debian.org/bullseye/libtraceevent-doc/tep_print_num_field.3.en.html	CC-MAIN-2022-40	refinedweb	498	61.87

By default, your top level devenv/bin directory will contain a script called openmdao that has a subcommand called “test” that uses a Python package called nose to run all of the unit tests for any package that you specify. For example, to run the full set of openmdao unit tests, type: openmdao test which should generate output something like this: ........................................................................ ........................................................................ ..................................................................... ---------------------------------------------------------------------- Ran 293 tests in 142.846s OK To run unit tests for a package only, for example openmdao.main, type: openmdao test openmdao.main To get a list of options available with openmdao test, type openmdao test --help from the devenv directory. Since the openmdao test command uses the nose testing framework internally, all options available when running nosetests should also be available when using openmdao test. Note that when you run the openmdao test script, some tests might fail if you do not have Internet access. A Python package called coverage, which is accessible through openmdao test, makes it easy to determine if your tests cover every line of code in your source files. To get a coverage report for the openmdao package, go to the devenv directory and type the following: openmdao test openmdao --with-coverage --cover-package=openmdao The report should look something like this: ................................................................................ ..

If you edit source code, the coverage data may become inaccurate, so you should clear the coverage database by issuing the following command: openmdao test openmdao --cover-erase Note that the coverage package is not included with openmdao, so to use it you’ll have to install it in your openmdao environment like this: easy_install coverage Generally, you should write your tests using Python’s unittest framework if possible, although the nose package is able to find and run tests that do not use unittest. The following is a simple example of a unit test written using the unittest framework. import unittest class TestSomeFunctions(unittest.TestCase): def setUp(self): # put setup code here. It will run at the beginning of each # test function (function with name that starts with 'test') def tearDown(self): # put code here that you want to be run after each test function # is completed def testfunct1(self): # a test function def test_some_stuff(self): # another test function if __name__ == '__main__': unittest.main() The unittest.TestCase class provides a number of functions to test output during a test function. For example: Often in a test you will want to make sure that a specific exception is raised when a certain thing happens, and usually you want to verify that the error message contains certain information. The unittest framework provides an assertRaises function that does part of this job, but it does not allow you to check the error message. So the preferred way to test exceptions is shown in the code below. In this example, we will assume that the exception we are interested in is a ValueError. Note that we would place our test function inside of our unittest.TestCase derived class. def test_myexception(self): try: # perform action here that should raise exception except ValueError, err: self.assertEqual(str(err), "this should be my expected error message") else: self.fail('expected a ValueError') Note that the else block after the except is important because we want the test to fail if no exception is raised. Without the else block, the test would pass if no exception were raised. The OpenMDAO documentation includes quite a few examples of Python code. These examples illustrate how to use features of the OpenMDAO API as well as how to develop new components and plugins. Thus, it is imperative that any code examples included in the documentation (particularly the tutorials and the Developer Guide) be tested to ensure that the code is error-free. Fortunately, there are tools built into the Sphinx reStructuredText processor that make the process of testing code samples much easier. Sphinx includes a builder called doctest as a plugin in its standard library. Instead of building a readable document as is done by the HTML builder, the doctest builder scans the documentation files for code blocks and tests them. Two types of code examples are found in the documentation. The first type is a block of code as would be found in a Python script: from openmdao.examples.enginedesign.engine import Engine my_engine = Engine("new_engine") The second type of code example is a copy of an interactive shell session: >>> print "Hello!" Hello! Both of these types of code samples must be tested, although the way to accomplish this differs slightly in each case. Unlike the doctest module built into Python, which can handle only shell session blocks, the doctest builder included with Sphinx can handle both of these code sample types. The doctest builder in Sphinx provides a flexible environment to easily and effectively test blocks of code using a set of directives. The test code directive is used to mark a block of text that should be tested and treated as Python code. It is not always possible to execute a standalone block of Python code without first executing some preliminary code containing any prerequisites (e.g., imports.) The testsetup block makes it possible to run the preliminary code. This block is hidden by default, so it does not show up in the generated HTML documentation. Additionally, the testoutput block should include any output that is generated by the testcode block so that it can be tested. A simple example of how to implement these three blocks is shown here: .. testsetup:: Group1 # Put any preliminary code that needs to run before the sample code. # This block does not show up when Sphinx builds the HTML .. testcode:: Group1 # This is the sample code that shows up in your docs .. testoutput:: Group1 # If your code block outputs anything when executed, then that output # needs to go in this block. Group1 is a label that we’ve given this set of blocks. You can have multiple labels in your documents. Also, the testsetup and testoutput blocks are both optional. Some code examples don’t need either. You can have multiple testcode blocks for a single testsetup block. The environment is preserved across all of the testcode blocks in a given group, so that the code executed in the first testcode block in Group1 affects all later blocks in Group1. The label is optional; when not explicitly defined, default is used. The doctest directive is used to specify blocks of interactive shell Python code. If the directive is omitted, the doctest builder can often find the Python blocks by itself, but it is still a good idea to include it so that you can control the environment. .. doctest:: Group2 >>> # This code is tested The doctest blocks share their workspace in a similar manner as the testcode blocks. Other options can be enabled for the doctest blocks, but so far the default ones have been fine. More details on using the doctest builder can be found here: At times it is more efficient to directly include code from a source file. The built-in Sphinx directive that enables this is called the literalinclude block: .. literalinclude:: ../../openmdao.examples/openmdao/examples/enginedesign/engine_wrap_c.py :start-after: engine_weight = 0.0 :end-before: # end engine.py :language: python The first line contains the relative path location of the file that is to be included. Since you rarely want to include an entire file, the options start-after and end-before can be used to define the bookends that bound the block of text to be included. Sometimes, it makes more sense to grab specific lines from a file. This can also be done with the lines option. .. literalinclude:: ../../openmdao.examples/openmdao/examples/enginedesign/engine_wrap_c.py :lines: 3,7-12,45 :language: python More details on the literalinclude directive can be found at. Tracebacks don’t have to be accurately reproduced (and they can’t be anyway). Handle these by replacing the traceback with ellipses: >>> my_engine.set("throttle",3.0) Traceback (most recent call last): ... ValueError: Variable 'RPM' must be a float in the range [0.01, 1.0] but a value of 3.0 <type 'float'> was specified. Indentation is not preserved between code blocks in the same group. This means that all functions and class definitions effectively close when the block ends. If you need to show code from the middle of a function class, you may have to get creative in what you place in your testsetup block (e.g., defining self as something.) Take care to assure that each block of code is being tested. One way to do this is to purposefully introduce an error into a block to verify that it is caught. Be wary of including code by line number. If the source file is changed and lines are added or removed, then the included code might not be what was intended. To include a numerical example in a doctest block, you can use ellipses to match the output to a specific tolerance. For example, this block of text passes: >>> import numpy >>> numpy.pi 3.14... Sphinx automatically generates syntax highlighting for the code block, but it can get confused if you mix tabs and spaces. The doctests are automatically run whenever you run openmdao test, but you can also run them separately. In an active openmdao virtual environment, type: openmdao test_docs This command builds the documents and then runs the doctests. If the test was successful, you should see output similar to the following: Doctest summary =============== 156 tests 0 failures in tests 0 failures in setup code build succeeded. If any tests fail, they will be noted in this summary, and specific tracebacks will be given for each failure earlier in the output. Note If you change the docs, rebuild the documentation by running openmdao build_docs and display them by typing openmdao docs.	http://openmdao.org/releases/0.2.5/docs/dev-guide/testing.html	CC-MAIN-2019-43	refinedweb	2,001	65.01

I have 5 classes class 1- main (basically controlls everything except recognizing where the letters are located in the word and printing the hangman picture) class 2- char_array (sees if the letter is in the word multiple times, and prints the letters the operator has figured out (ex: bumb-e) ) class 3 - graphics (just full of methods that print the hangman on the screen depending on how many letters you have gotten wrong) class 4 - numbers (just has one method to decide what hangman picture to display) class 5 - wordlist - a class that chooses a word from a list of many) Where I am stuck is that the variables in the char_array class reset each time the init() or some_function() that gets called. Therefore, if i have a word with two of the same letter, the count gets messed up AND the the word with the dashes that the user sees (ex: G--gle) gets reset every time, so only the letter that you just entered will show up(ex: i enter g: G--g--, then i enter o: -oo---) Here is the main class import java.lang.reflect.Array; import java.util.Scanner; import java.util.Random; import java.util.Arrays; import java.util.HashMap; import java.io.*; public class main{ public static void main(String[] args){ graphics graphics = new graphics(); numbers numbers = new numbers(); WordList words = new WordList(); main main = new main(); Scanner input = new Scanner(System.in); //String word[] = {"h", "i"}; String word = new String(words.getword()); String guessed_letters = new String(""); int guesses_right = 0; int guesses_wrong = 0; int length = word.length(); System.out.println("Hello, this is a hangman game. Good luck!"); System.out.println(word); while(guesses_right != length && guesses_wrong != 6){ System.out.println("Please enter a letter: "); String x = input.nextLine(); if(isAlpha(x) && !(x.length() >1)){ x = x.toLowerCase(); if(word.contains(x) && !(guessed_letters.contains(x))){ System.out.println("------------------------------"); System.out.println("Good job, that is in the word"); char_array char_array = new char_array(); guessed_letters = guessed_letters + x; char_array.init(word, x); char_array.some_function(); System.out.println("DEBUG" + char_array.counter); guesses_right = guesses_right + char_array.counter; guesses_right++; numbers.display_hangman(guesses_wrong); System.out.println("Guessed_letters:" + guessed_letters); } else if (guessed_letters.contains(x)){ System.out.println("------------------------------"); System.out.println("I'm sorry, but you have already entered that number"); } else if (!word.contains(x)){ //guessed_letters = guessed_letters + x; if (guessed_letters.contains(x)){ System.out.println("------------------------------"); System.out.println("I'm sorry, but you have already entered that number."); } else{ System.out.println("------------------------------"); System.out.println("Sorry, that is not in the word"); guesses_wrong++; numbers.display_hangman(guesses_wrong); } guessed_letters = guessed_letters + x; } }else{ System.out.println("I'm sorry, but it appears you have entered something that is invalid"); } } if( guesses_wrong == 6){ System.out.println("I'm sorry but it appears that you have lost. The word was " + word + ". Maybe try again?"); } else{ System.out.println("Congratulations!! You have won. The word was " + word + ". Maybe try again?"); } } public static boolean isAlpha(String name){ return name.matches("[a-zA-Z]+"); } } ------------------------------------------------------------------------------- here is the char_array class import java.lang.String; public class char_array { public void init(String a, String B)/>{ word = a; x = b; } main main = new main(); graphics graphics = new graphics(); public String word; public String x; public int counter = 0; public void some_function() { //variable to increase in case of double letter char what_user_sees[] = new char[word.length()]; char charArray[]=word.toCharArray(); for(int i = 0; i <word.length(); i++){ what_user_sees[i] = '-'; } for(int h=0;h<word.length();h++){ if (charArray[h] == x.charAt(0)){ what_user_sees[h] = x.charAt(0); counter++; //System.out.println(what_user_sees); } } System.out.println(what_user_sees); //print the thing with the hash marks } } These classes seem to be the ones that are causing the trouble. Could you guys modify the code for me so that the variables don't get reset every time? Thanks in advance, Brady I would post the other classes, but they will just take up space, and i really don't think you will need them. PS - if you guys could give me some better coding styles, that would be great. I'm just a beginner, So I'll take any advice that I can get.	http://www.dreamincode.net/forums/topic/317592-variables-reset-after-each-method-call/	CC-MAIN-2018-09	refinedweb	687	58.69
I guess one of the reasons a lot of C programmers could not digest Java was because Java didn't let them manipulate pointers. Anyway C# supports pointers. You can use the unsafe keyword to inform the compiler that the following function or block is unsafe. And once you do that you can use pointers in that unsafe area. using System; class nish { unsafe static void Increment(int* p) { //increment the int pointed to by p p=p+1; } public static void Main() { int i = 1; //we pass the address of the int to the function as it expects a pointer unsafe { Increment(&i); } //now we print out the value of i Console.WriteLine (i); } } When you run the program, you'll see 2 printed on screen. This is because you have passed the address of the variable i to the function Increment. Variable i is created on the stack. &i gives its address on the stack. Thus when within the function Increment, p is pointing to i's address. Thus when we add 1 to p we are actually incrementing i; The following program should make things clearer to you. using System; class nish { unsafe public static int Main() { int j=100; int k=100; Console.WriteLine("address of j={0} and address of k={1}",(int)&j,(int)&k); Console.WriteLine("j={0} k={1}",j,k); int p; p=&j; Console.WriteLine("p now points to {0}",(int)p); p=200; Console.WriteLine("j={0} k={1}",j,k); p=&k; Console.WriteLine("p now points to {0}",(int)p); p=300; Console.WriteLine("j={0} k={1}",j,k); return 0; } } When I ran it I got the below output. You would get something similar. The output will clearly give an idea of what's going on. address of j=1244312 and address of k=1244308 j=100 k=100 p now points to 1244312 j=200 k=100 p now points to 1244308 j=200 k=300 First we assign the address of j to p. Thus when we change p we automatically change j. Then we change p to point to k's address and thus when we change p we are actually changing k Also remember than the pointer variable p itself has an address. This following program will make that clear. using System; class nish { public static void Main() { unsafe { int a=100; int p; p=&a; Console.WriteLine("address of a is {0}",(int)&a); Console.WriteLine("p now points to {0}",(int)p); Console.WriteLine("address of the pointer variable p is {0}",(int)&p); } } } On running it I got the below output. You'll get similar output too. Notice the alternate use of the unsafe keyword address of a is 1244312 p now points to 1244312 address of the pointer variable p is 1244308 In my case 1244308 is the address of the pointer variable p. The contents of that address is 1244312 which is an address. Thus when we take p we are referring to the address 1244312. Try printing out p and it will print out the contents of 1244312 which happens to be 100 in the above case. I hope things are clearer now. Okay. In this final program I'll show you how to use pointers to manipulate a character string. In this program there is a function that takes a string and encodes or decodes it using XOR. If you pass a string to it it will encode it and if you pass the encoded string to it, it will decode it. Of course this is by no way a safe or practical encryption method. I am using it merely to demonstrate the use of pointers. using System; class nish { public static void Main() { string s="Code Project is cool"; Console.Write("the original string : "); Console.WriteLine("{0}\r\n",s); char[] b = new char[100]; s.CopyTo(0,b,0,20); Console.Write("the encoded string : "); unsafe { fixed(char p=b)NEncodeDecode(p); } for(int t=0;t<20;t++) Console.Write(b[t]); Console.WriteLine("\r\n"); Console.Write("the decoded string : "); unsafe { fixed(char p=b)NEncodeDecode(p); } for(int t=0;t<20;t++) Console.Write(b[t]); Console.WriteLine(); } unsafe public static void NEncodeDecode(char s) { int w; for(int y=0;y<20;y++) { w=(int)(s+y); w=w^5; (s+y)=(char)w; } } } This is the output I got. You should get this too. the original string : Code Project is cool the encoded string : Fja`%Uwjo`fq%lv%fjji the decoded string : Code Project is cool You will notice a new keyword here called fixed. When you precede a statement or a function with fixed you are instructing the .Net garbage collector not to relocate that variable till the statement or function has finished. The fixed keyword is only allowed in an unsafe context. If we don't use fixed there is little point in using pointers as the results would be unpredictable if the garbage collector keeps relocating the managed variables. Luckily the compiler won't let you point to managed variables unless you specify the fixed keyword. In the function you can see that I use the expression (s+y). s is the address pointing to the string. y is incremented starting from 0 and ending upto 19. Thus when I give (s+y) I get the pointers to characters in those locations. Lets assume s points to 1000. Thus (s) will give me the contents of location 1000. Now if I give (s+1) I get the contents of 1002, and for (s+2) I get 1004 and so on. The compiler knows I am pointing to a character array and thus each increment jumps 2 bytes as char is a 16 bit value. C# actually maps char to the .Net type System.Char. Sometimes, you might need to call the Win32 API. And there are API functions, quite a good number of them to be precise, that take pointers as arguments and often return data via pointers. The following program is an example where such a call is made. Of course, there are other means to obtain the Windows folder from .NET, but the point of the program is to demonstrate the use of unsafe blocks in such a scenario where we need to call an API function that expects pointers. using System; using System.Text; using System.Runtime.InteropServices; class Class1 { [DllImport("kernel32", SetLastError=true)] static extern unsafe uint GetWindowsDirectory(byte lpBuffer,uint uSize); static void Main(string[] args) { byte[] buff = new byte[512]; unsafe { fixed(byte *pbuff=buff)GetWindowsDirectory(pbuff,512); } ASCIIEncoding ae = new ASCIIEncoding(); System.Console.WriteLine(ae.GetString(buff)); } } Please be careful when writing unsafe code. Any small error, even a silly typing mistake, might crash your program randomly and unpredictably. The error might also be a rarely occurring one and thus harder to debug. But those of you who had used pointers in C/C++ and want to use them in C# may do so at their leisure. Thank You.

City of Vancouver’s short term accommodation bylaw fully came into force today. There was much talk of “2,000” Airbnb units being deactivated. But did it really happen? It appears that Airbnb has deactivated approximately 5% of the listings that were active on August 31. I took a random sample 832 of City of Vancouver hosts on Airbnb August 31 between 4pm and 6pm Pacific Time. 218 out of the 832 (27%) of them were without licences and facing deactivation. I ran a follow up today between 1pm and 2pm. Here’s what I found Table1: What happened to the listings without licenses on Aug 31 That means approximately 5% of Airbnb listings that were active in my sample have been delisted. If we go by Jens von Bergmann’s figure of 4,700 total listings1), that works out to about 250 listings being taken off the platform. But the number of people who are cheating the system far exceed the number of listings yanked from the platform. I’m currently collecting data post-purge, and here’s what I have found with my fresh sample of 1,634 listings collected so far today. Table 2: Summary of problems with licences 459 listings, or 28%, share a licence with one or more other listings. This means that Airbnb and City have done nothing to crackdown on commercial operators. Licences for 152, or 9%, did not appear in the City of Vancouver business license database. 73 out of the 832 listings in my sample, or 4%, claimed to be “Exempt” even though they were for less than 30 days. Further 17 listings, or 1%, had obviously fake license numbers such as 00-0000. This means 11% of the listings are either fake or are claiming to be exempt when they probably aren’t. In summary, the “great purge” did not happen. Even amongst the listings with licences, 43% are problematic. A lot of these problems can be solved by introducing license auto-verification2). Data I’m happy to share my SQL database if anyone wants to play around with it. Just get in touch with me. Bonus Here’s a nify two-liner to extract City of Vancouver short term rental licences from the Open Data portal Json file. import json stral = [f['properties']['LicenceNumber'] for f in json.load(open("/path/to/Politics/business_licences.json"))['features'] if f['properties']["BusinessType"] is not None and 'Short-Term Rental' in f['properties']["BusinessType"]]	https://rezel.ca/2018/09/only-5-of-vancouver-airbnb-listings-deactivated/	CC-MAIN-2020-10	refinedweb	412	64.41
Warning: You probably shouldn’t be using jQuery any more, this is an old article. Please tread with caution when referencing this article. Here is a simple and effective way to pass different jQuery contexts around for manipulation in client packages. Recently I was presented with the issue of instantiating multiple iframes within a single page, all of which would have a small package loaded inside them to run and manipulate itself. These packaged units needed a handle on their own iframe as well as the parent document. $ is setup to work off the current document. When no context is provided to the jQuery() selector method then the context of document is used. I could have manipulated the selector or used other jQuery helper methods to get a handle on the parent document, but that would get messy very fast and could make the packaged code difficult to read. A cleaner solution is to have two seperate selector handles, one on the unit iframe document and one on the top.document. This approach can be used to limit the selector for anything but for my case I needed top.document. import $unit from 'jquery' import $top from 'utils/jquery-top' In the above example jquery is just the defacto jquery installed as a dependency via npm. The second import statement is a custom abstraction to the defacto jquery library which allows me to override the seletor method and limit the context to top.document. import jQuery from 'jquery' jQuery.noConflict() let bling = function(selector, context = top.document) { return new jQuery.fn.init(selector, context) } bling.fn = bling.prototype = jQuery.fn jQuery.extend(bling, jQuery) export default bling Now when I’m in the unit packaged code I can have a handle on both the top.document as well as the individual unit iframe document. $unit('.content-body').text('This is an example') $top('.unit-iframe').addClass('showing')	https://hbrysiewicz.com/2016-02-17-jquery-scope.html	CC-MAIN-2021-43	refinedweb	317	55.95
�StdAfx� files yet as these are needed. The point in this step is to simply copy and paste your class (�foo�) into the header and source files created. It should be a simple concept to grasp, but if you are skeptical you can alternatively just add your �foo� �Export�. When it is being included in another project that does not use the source code, you will need to �Import�. This is probably the harder part of understanding the DLL as it is not necessarily implemented for you and requires a little effort before understanding. As a side note, the �resource.h� is only required by DLLs that have dialogs in them. In this case, you will have to remember that you may have several �resource.h� files then and will have to include a full path statement to each �resource.h� file. This article will show in the following example what is probably the best method (keeping in mind that if a project needs this resource file it must manually be added to the project including the full path to it). StdAfx.h // // MSVS included headers, definitions, etc. // // Somewhere near the bottom //This is the project macro preprocessor definition //you will be adding shortly. #ifdef DLL_EXPORTS //This is to be used for the class header file. #define DLL_BUILD_MACRO __declspec(dllexport) #else #define DLL_BUILD_MACRO __declspec(dllimport) #endif #ifndef _DLL_BUILD_ //Why do this? Is it necessary? Yes. #define _DLL_BUILD_ DLL_BUILD_MACRO #endif //make sure resources are included here, if desired, //to prevent ambiguous //callings to different resource.h files. #include �resource.h� // // Rest of file // foo.h #ifndef _FOO_H_ #define _FOO_H_ // // Miscellanous here // /This part automatically includes any libraries when called. When this file is built within the DLL project, it will not be called because of our preprocessor macro definition �_FOO_DLL_�. However, when this file is called from another project, not part of this build, it appropriately chooses the correct library and includes them for you. WHAT this means is that you will not have to add the library to the project link settings for a project that requires this DLL. This helps to avoid the tedious task of linking to several custom DLLs. Note there are two different libraries here and probably not necessary but give you an idea of how to separate debug versions from release versions./ #ifndef _FOO_DLL_ #ifdef _DEBUG //You will be building a debug program that //uses this file, so in this case we //want the debug library. #pragma comment( lib, �food.lib� ) #else //You will be building a release program that //uses this file, so in this case we //want the release library. #pragma comment( lib, �foo.lib� ) #endif #endif #ifndef _DLL_BUILD_ #define _DLL_BUILD_ //Makes sure there are no compiler errors. #endif class _DLL_BUILD_ foo private: // // Your members // public: // // Your functions // }; #endif foo.cpp #include �stdafx.h� //place first #include �foo.h� // //Your code // _FOO_DLL_� and � DLL_EXPORTS� at the end of the list of other macro definitions. Be sure to separate each new MACRO with a coma (�,�). Make sure to do this for the release version too, as you will have to redo these next steps for each type of build. Make sure to build with any �debug info� and/or �browse info� if this is a debug version and if you want to debug the DLL later using the MSVS debugger. Debug.bat Copy �Debug\foo.lib� �c:\<libraries dir>\food.lib� REM copy the dll file to the windows system32 REM directory to make the DLL easily REM accessible. Note that you will have to install or include the REM dll file in your distribution package for the program that uses it. Copy �Debug\foo.dll� �c:\%system dir%\system32� Copy �foo.h� �c:\<headers dir>� Release.bat Copy �Release\foo.lib� �c:\<libraries dir>� �Release\foo.dll� �c:\%system dir%\system32� Copy �foo.h� �c:\<headers dir>� �c:\windows\system32� �Debug.bat� and �Release.bat� files and then rebuild the project to have them copied. Also note that in MSVS it is easy to add custom directories for new header directories to search, but unfortunately not DLL directories. Go under �Tools->Options� in the menu bar and then under the �Directories� tab button. Where �<libraries dir>� above in the batch file should be included under �Library files� in the �Show directories for� combo box and �<headers dir>� in the �Include files�. Windows.

Zipping Lists in Python If you need to work with multiple lists at once the zip builtin is the tool you are looking for. The zip function is a Python builtin that aggregates its arguments into a list of tuples. What is the zip function and how does it work? zip takes an iterable (with zero or more elements) and aggregates them into a single list. This list will contain tuples, where the tuples contain an element from each list. Typically it is used with two lists, like so: for i in zip([1,2,3], ['a','b','c']): print(i) Output: (1, 'a') (2, 'b') (3, 'c') Type of the return value In Python version 2 zip returns a list, while in Python 3, the return value is an iterator: Python 2 print(zip([1,2,3], ['a','b','c'])) output: [(1, 'a'), (2, 'b'), (3, 'c')] Python 3 print(zip([1,2,3], ['a','b','c'])) output: <zip object at 0x7f0b1bce7500> How to import zip zip is a python builtin, it can be used to work with lists in parallel, no need to import, it should be accessible by default as it is defined in the builtin namespace. What happens if the lists are not of equal length? If you pass lists of different lengths, the return value will have the length of the shortest list: print(zip([1,2,3], ['a','b'])) <zip object at 0x7f0b1bce7500> output: [(1, 'a'), (2, 'b')] Advanced use cases - tricks using zip zip is can be surprisingly powerful tool, here are some nice patterns to showcase what you can do with it: Zipping multiples lists As I’ve already mentioned, zip is not limited to zipping only two lists, in fact, you can pass it any number of arguments. The result will create tuples which have the length equal to the number of arguments passed to zip. This pattern is used quite often in Python: for i in zip([1,2,3], ['a','b','c'], [0.1, 0.2, 0.3]): print(i) output: (1, 'a', 0.1) (2, 'b', 0.2) (3, 'c', 0.3) Iterating two lists in parallel Python has a feature called tuple unpacking, which means that you can assign values to multiple variables in a single expression: a, b, c = (1, 2, 3) print(a) print(b) print(c) output: 1 2 3 This can be used in combination with zip to iterate on two (or more) lists in parallel: for i, j, k in zip([1,2,3], ['a','b','c'], [0.1, 0.2, 0.3]): print("{}, {}, {}".format(i, j, k)) output: 1, 'a', 0.1 2, 'b', 0.2 3, 'c', 0.3 Combining two lists into a dictionary (keys+values) A dictionary can be defined using a list of 2-long tuples (pairs), so you can easily zip together two lists. keys = ['a','b','c'] values = [1, 2, 3] print(dict(zip(keys, values))) output: {'a': 1, 'b': 2, 'c': 3} Zipping a list of lists If you have a list of lists (in other words: a variable number of lists), you can zip them together as well, you only need to unpack them using the operator: l=[[1,2,3], ['a','b','c'], [0.1, 0.2, 0.3]] for i in zip(l): print(i) output: (1, 'a', 0.1) (2, 'b', 0.2) (3, 'c', 0.3) The inverse of zip - unzipping a list of tuples into multiple lists The above pattern can be used to revert zipping a list of lists as well. zipped_list = [ (1, 'a', 0.1) (2, 'b', 0.2) (3, 'c', 0.3) ] first_elements, second_elements, third_elements = zip(zipped_list) print(first_elements) output: [1, 2, 3] Transposing a matrix Generalizing this means that pattern shown above (unpack+zip) can be used to transpose martixes: matrix=[[1,2,3],[4,5,6],[7,8,9]] print(list(zip(matrix))) output: [(1, 4, 7), (2, 5, 8), (3, 6, 9)] Returning a list of lists instead of a list of tuples There is a slight issue with the example above, as the list of list turned into a list of tuples. It can be easily fixed though, you can turn lists into tuples in a list comprehension: matrix=[[1,2,3],[4,5,6],[7,8,9]] print([list(row) for row in zip(*matrix)]) output: [(1, 4, 7), (2, 5, 8), (3, 6, 9)] Zip longest I’ve already mentioned, that zip will return a list that is equal in length with the shortest of its arguments. There is very similar function defined in the itertools module, called zip_longest, which behaves exactly like zip, but pads the resulting tuples to the length of the longest of its arguments. from itertools import zip_longest list(zip_longest(['a', 'b', 'c'], [1])) output: [('a', 1), ('b', None), ('c', None)] You can also set a different padding value instead of None using the fillvalue keyword argument: from itertools import zip_longest list(zip_longest(['a', 'b', 'c'], [1], fillvalue='X')) output: [('a', 1), ('b', 'X'), ('c', 'X')]	https://pythonin1minute.com/zipping-lists-in-python/	CC-MAIN-2022-21	refinedweb	841	63.53

And what's the purpose of int m = 65; or of bufflen = strsize; and why is bufflen passed to construct?

The Microsoft Dynamics CRM Team Blog News and views from the Microsoft Dynamics CRM Team You may have noticed that the Microsoft Dynamics CRM 4.0 SDK contains Web services, assemblies and helper code that have LOTS of the same classes. Which should you use, when and why? It depends on what you are creating: A plug-in is an assembly that it registered to run before or after CRM does it’s processing for an action. Use: Use the SDK assembly because contains the IPlguin and IPluginExecutionContext. It also contains the helper classes you can use for building queries, instantiating types and enumerations you can use to make your code more readable and maintainable. Use the SDK type proxy assembly because it contains the messages (request and response classes). This assembly also includes all the entity classes but do not use them! In other words, do not use the account or contact classes; instead use the DynamicEntity class, which provides a property bag to access the attributes of an entity instance (record). This is better for you anyway, since the entity classes included in this DLL will not contain any of your customizations. The entity classes are deprecated and will be removed from this assembly in a future version. Custom workflow activities are assemblies that can be called from a workflow. Use the SDK assembly because it contains the Workflow namespace which includes all the classes you need to create custom workflow activities. You can use the messages (request and response classes) contained in the SDK type proxy in your custom workflow activities. The same warning against using the entity classes applies here. If you are adding new functionality to the CRM Web application or to the Outlook client, you should use the Web services. This includes adding custom ASPX pages or adding ISV menu items that calls your custom code. Remember that if you customize your entities, you need to recompile any code that uses those customized entity classes. Use: There is another Web service covered in the CRM Deployment SDK but this is not used in this sort of custom code. If you are adding functionally to the CRM Outlook client, use the Outlook SDK assembly because it contains methods to detect whether the client is online or offline, to make the client go online or offline or to synchronize the data after going online. You can also use the helper classes by adding the C# files from CrmHelpers. These classes can be used for easier type instantiation, for building queries and contains enumerations you can use to write more readable and maintainable code. You can also get the identical helper classes by adding the Microsoft.Crm.Sdk.dll assembly. Adding this DLL requires a bit more care because the SDK assembly contains the classes for the metadata Web service so this may be confusing if you are also using the MetadataService. Do not include Microsoft.Crm.SdkTypeProxy.dll to these types of projects. The Web services contain the entity classes and the message classes so this assembly is not needed. Read about these topics in the SDK: Amy Langlois PingBack from Can I use CrmService (custom entities and customized entities) in Plugins? Plugins can be parts of ISV solution code too! In other words, I don't understand, why I should use dynamic entity only in Plugins. Okay, so I'll give you a baker's dozen of some really good stuff from the perspective of a Microsoft	http://blogs.msdn.com/b/crm/archive/2008/06/23/web-services-dlls-or-what-s-up-with-all-the-duplicate-classes.aspx	CC-MAIN-2015-48	refinedweb	582	61.26
STAT 19000: Project 6 — Spring 2022 Motivation: We will pause in our series of pandas and numpy projects to learn one of the most important parts of writing programs — functions! Functions allow us to reuse snippets of code effectively. Functions are a great way to reduce the repetition of code and also keep the code organized and readable. Context: We are focusing on learning about writing functions in Python. Scope: python, functions, pandas, matplotlib Dataset(s) The following questions will use the following dataset(s): /depot/datamine/data/whin/190/combined.csv /depot/datamine/data/flights/subset/.csv Questions Question 1 In project 5, you read in two separate, but related datasets, and used the pandas merge method to combine them. In this project, we’ve provided you with a combined dataset already, called combined.csv. Read in combined.csv into a data frame called dat. Your friend shared the following code with you. import plotly.express as px def plot_stations(df, ids): df = df.groupby("station_id").head(1).loc[df['station_id'].isin(ids), ('station_id', 'latitude', 'longitude')] fig = px.scatter_geo(df, lat="latitude", lon="longitude", scope="usa", hover_name="station_id") fig.update_layout(geo = dict(projection_scale=7, center=dict(lat=df['latitude'].iloc[0], lon=df['longitude'].iloc[0]))) fig.show(renderer="jpg") Please do the following: Give a 1-2 sentence explanation of what this function does. Use the function to plot 2 or more stations, BUT, use the function in two different ways (with the same result). Use tuple unpacking in 1 call of the plot_stationsfunction, and do not in the other. Code used to solve this problem. Output from running the code. Question 2 In project 5, question 5, you wrote a function called plot_stations that given a data frame, would plot the locations of the stations on the map. Modify your plot_stations function so that it has an argument called weighted that defaults to False. If weighted is True, then the stations will be plotted with a size proportional to the number observations at each station. plot_stations(df) # plots all stations same size plot_stations(df, weighted=False) # plots all stations same size plot_stations(df, weighted=True) # plots all stations with size proportional to the number of observations for the station Code used to solve this problem. Output from running the code. Question 3 There are many columns in our data frame with numeric data. Some examples are: temperature_high, temperature_low, barometric_pressure, wind_speed_high, etc. Wouldn’t it be (kind of) cool to have an option in our plot_stations function that would weight the size of the points on the map based on those values instead of the number of observations? Modify the function so that it has another argument called weight_by that defaults to None. If weight_by is None (and weighted is True), the points on the plot should be sized by number of observations (like in question 2). Otherwise, weight_by can accept a string with the name of the column to base the point sizes on. For example: plot_stations(dat, weighted=True, weight_by="temperature_high" would create a plot where the size of the points are based on the median value of temperature_high by station. Of course, not all of the columns in our dataset are appropriate to weight by. Please demonstrate your function works by running the following calls to plot_stations. plot_stations(dat, weighted=True, weight_by="temperature_high") plot_stations(dat, weighted=True, weight_by="temperature_low") plot_stations(dat, weighted=True, weight_by="wind_speed_high") plot_stations(dat, weighted=False, weight_by="barometric_pressure") plot_stations(dat, weighted=True, weight_by=None) Code used to solve this problem. Output from running the code. Question 4 You’ve learned a lot about plotting maps in plotly, the groupby method (most likely), and hopefully functions as well! /depot/datamine/data/flights/subset directory. Write a function that creates any new plot using some or all of the data in the subset directory. The plots could be maps, other plots, anything you want! The goal should be to make the function useful for exploring flight data in the provided format. Take advantage of the tuple packing and unpacking, default arguments, etc. You could even have a function inside another function (a helper function). Do you best to challenge yourself and have fun. Any solid effort will receive full credit. Code used to solve this problem. Output from running the code. Question 5 (optional, 0 pts) Write a function that accepts the WHIN weather dataset (as a data frame), and an argument n. This function should plot the largest n distances between stations on a map. See here for examples of plotting lines on a map. If you are feeling very adventurous, there is a data structure called a kdtree that you can use to very efficiently find the n closest or furthest points, however, this is probably not necessary as there are not that many distances to calculate for this dataset. Code used to solve this problem. Output from running the code.	https://the-examples-book.com/projects/current-projects/19000-s2022-project06	CC-MAIN-2022-33	refinedweb	819	56.76
. Code Well, the main target was to get started with Python, the best way for doing so (once you know atleast another language) is to struggle through. Here is the github link for the source: Read the comments at the beginning of the file to get the parameters. Commandline arguments --id <apikey> : Specifies the API Key --blog <blogurl> : Specifies the blog URL --noplot : If this switch is present, on-screen plots will not be shown --noget : If this switch is present, the files will not be downloaded from web API, and local copy will be used. The local copy should be in the same directory as the script. Note that the --id and --blog is mandatory. Others take default values. The script plots on the screen by default and stores the plots as pdfs, and fetches the stats every time the script is run. An example run is as follows. ./wp_stats_demo.py --id abcdef012345 --blog Also, make sure to run the script in Python3. The main logic to fetch the blog information is in the initialize function. If you invoke the script without the --noget (default), then for each type of stat type of the API, wp_stats_fetch is called. The wp_stats_fetch function makes a URL according to the wordpress.com API’s manual by using the make_wp_url function, which it then uses to fetch the specific stat. The format can be csv, json and xml which is also configurable through the wp_api_args parameter. The wp_stats_fetch is the main function which should interest you. I posting the current state of only the portion of the code below, which fetches the information using the wordpress.com API. def wp_stats_fetch (wp_api_args, file_save): wp_url = None; try: wp_url = make_wp_url (wp_api_args["api_key"], wp_api_args["blog_id_uri"], wp_api_args["table"], wp_api_args["post_id"], wp_api_args["end"], wp_api_args["days"], wp_api_args["period"], wp_api_args["limit"], wp_api_args["summarize"], wp_api_args["form"] ); response = urllib.request.urlopen (wp_url); file_ext = None; if wp_api_args["form"]: file_ext = "." + wp_api_args["form"]; else: file_ext = ".csv"; text = response.read().decode("utf-8"); m = re.search ("Error:", text); if m: raise WPStatsFetchError ("Incorrect url arguments, Error returned"); return (-1); fp = open (file_save + file_ext, "w"); fp.write (text); fp.close (); except ArgError as e: print (e); return (wp_url); except Exception as e: print (e); return (wp_url); return 0; def initialize (my_api, my_blog, fetch_data = False): if (my_api is None) or (my_blog is None): raise ArgError ("An API key and a blog URL is mandatory"); return (-1); table_list = ["views", "postviews", "referrers", "searchterms", "clicks"]; post_id = None; end = None; days = -1; period = None; limit = -1; summarize = None; form = "csv"; req_url = None; fileprefix = "stats_"; if fetch_data is True: print ("\tDownloading data from web API. Overwriting local (if any)"); try: wp_api_args = { "api_key" : my_api, "blog_id_uri" : my_blog, "table" : None, "post_id" : post_id, "end" : end, "days" : days, "period" : period, "limit" : limit, "summarize" : summarize, "form" : form }; feedback_str = ""; for table in table_list: feedback_str = "Fetching " + table + " stats"; wp_api_args["table"] = table; sys.stdout.write (feedback_str), sys.stdout.flush (); retval = wp_stats_fetch (wp_api_args, fileprefix + table); if retval == 0: #feedback_str += " [SUCCESS]"; print (" [SUCCESS]"); else: #feedback_str += " [FAILED]"; print (" [FAILED]"); sys.stdout.flush (); #print (feedback_str); except Exception as e: print ("Exception: " + str (e)); else: print ("\tNot fetching data from web API. Using local"); return (True); The API key Replace the API key with your API key and the blog URL with your blog URL. Previously you could get API key from the Settings -> General, but now to get your API key, visit. Sign into, and select the Akismet basic subscription, which costs 0$, which is free. This should show you the API key. Or if you already have it subscribed, you can visit to get the API key in your mailbox. Some plots These are just a few different ways to view the stats, most of the plots have no real meaning, but this code can be extended to get the results one wants. So what now? Nothing much actually. As these APIs do not expose country information and some other information you cannot plot the maps. Although for busy blogs the postwise stats, search terms, clicks and referrers stats can get some good insight. Chances are I am not going to work on the script anymore, but if anyone is working or has worked on the wordpress.com stats API, I would be interested to check it out. This piece of code was extended and enhanced to make a dashboard in a web interface using Django, during the Hackathon organized at The Insight Centre for Data Analytics on August 2016. We made a team and enhanced this in 36 hours non-stop marathon. The team members were Siobhán Grayson and Gevorg Poghosyan, both researchers at The Insight Centre for Data Analytics, and ofcourse myself. We were able to do a pretty good work and had a lot of fun during that period. UPDATE - 01.01.2017: Added relevant portion of the code in the post. Added a little description for the relevant part of the code. - 16.01.2017: Added enhancement information. 11 thoughts on “Using WordPress.com stats API” Hi, it’s me again, i’ve looked through the post but not what i really want, there still no code for visitor Do you mean the visitor count or by country or other details per visitor? WordPress.com Stats API does not have any more details about the visitor information except the count actually. The country information you see the the dashboard is not accessible by this API, as far as I know. Just overall country is fine..but where can I get that? I think there is no way you can get country specific information from this API. Oh noi mos type it.. i mean over all visitor per day is fine.sorry You can do that by pulling daily visors, as I have demonstrated in the other post. I’ve tried it..but it’s only show views per day, could you advise which step did i miss? What you exactly mean by “overall visitors per day” is it just the count? Or also details like geographic locations? You can find per day post visits by doing some computation though. In wordpress stat there are views and visitor information, i can get views count by the method you provided but the visitor count, i cant find a way to get that information. Oh okay, like unique visitors which might generate more than one views per visitor. I think you still cannot get it through the API. Oh..okay, thank you for your help	https://phoxis.org/2016/12/30/using-wordpress-com-stats-api/?shared=email&msg=fail&replytocom=23680	CC-MAIN-2020-10	refinedweb	1,070	72.66
This is the mail archive of the gcc-patches@gcc.gnu.org mailing list for the GCC project. Hi Guys, I am applying the patch below to add a definition of ATTRIBUTE_PACKED to ansidecl.h along the lines of the other attributes defined in this file. This definition is now needed by the binutils sources. Does anyone know when the packed attribute was actually introduced into gcc ? I have not put a version number check into the patch because as far as I could tell it came in when support for __attribute__ was added.

Opened 4 years ago Closed 4 years ago Last modified 4 years ago #23063 closed Bug (fixed) send email 1.6.5 OK, 1.7c1 malformed packet in wireshark Description Hello, I'm working on a 1.7c1 application with Django, and my emails are not sent. My settings are: I tested my account with telnet, and smtplib, and everything goes smooth. The code I run: mail.send_mail('susu', 'body body', from_email, [to_email]) Under 1.6.5, the email is sent. Under wireshark, the data package is good. Under 1.7c1, the email is not sent. I open my wireshark, and look at the data packet. It shows that the packet is malformed. If I dump via filebased backend, there's no difference except the timestamp and message-id between the two versions. I copy you my packet dump from wireshark: Attachments (4) Change History (50) Changed 4 years ago by Changed 4 years ago by Dump of package malformed sniffing from Django 1.7 c1 comment:1 Changed 4 years ago by comment:2 Changed 4 years ago by Could you bisect to determine the commit that introduced the regression? comment:3 Changed 4 years ago by I upgraded my packages via pip and aptitude, and I always have malformed packet on every version of django if the body message = "test body". If I add some \n in the message, for example: msg = "test message body \n\n " , I dont have anymore the malformed packet, but the SMTP refuse my message. I'm gonna check again on my other computer if I still can send email with django, and then bisect. comment:4 Changed 4 years ago by I had a quick look at the dumps. Any chance you could provide us with the TCP conversation only, without the lower layers included? I doubt the problem is caused by something lower than TCP. Even though unlikely, if that's the case, the problem might not be related to Django at all. Also, the files the file backend generated might be useful as well.

I tried to change of version of django to the 1.6.5 but still bugging on my setup. Python 3.2 or 3.4. smtplib builtin python I assume. comment:6 Changed 4 years ago by I just changed of smtp server, going to google and not OVH, and the malformed packet is not here anymore. It works like a charm. Thanks anyway comment:7 Changed 4 years ago by Hello, First it is the first time I use this tool, so I'm really sorry if I don't use it properly. Secondly, English is not my natural language, so sorry for the errors. I reopen this thread because I have exactly the same problem. OVH is a professional provider massively used is europe and I can't use an other one as google to send my emails. So changing for gmail is not a well solution that correct the problem. I have not tested with the 1.6.5 version of django, but I can compare a mail sended with python and the other one sended with django. There is a problem with django.

Now the message seems to respect the "IMF" (internet message format) standards. Wireshark doesn't tag the packet as Malformed and the provider ovh accepts the message and the message is well sended. In the doc of python, as_string() is used as well.. (see ) Is there a reason why using as_bytes() here? comment:16 Changed 4 years ago by The last commit for that code is [5dfd824d]. comment:17 Changed 4 years ago by Yes, I found the same : So, what do you think? which one is good? It is sure that here on my local machine, this version using as_bytes() introduces a bug and as_string() corrects it.. comment:18 Changed 4 years ago by Not sure, but looking at that commit it seems like there's some backwards compatibility concerns to switching from bytes to string. I'll add Florian to CC. comment:19 Changed 4 years ago by message.as_string is broken beyond repair, so we can't use that. Interestingly in my tests both variants produce LF instead of CRLF, so I have yet to figure out where the CRLF is coming from. That said if Google accepts the mail it can't be that bad, so OVH should get their stuff together :þ comment:20 Changed 4 years ago by comment:21 Changed 4 years ago by Does this fix it: diff --git a/django/core/mail/message.py b/django/core/mail/message.py index da9891f..961d1a8 100644 --- a/django/core/mail/message.py +++ b/django/core/mail/message.py @@ -149,7 +149,7 @@ class MIMEMixin(): """ fp = six.BytesIO() g = generator.BytesGenerator(fp, mangle_from_=False) - g.flatten(self, unixfrom=unixfrom) + g.flatten(self, unixfrom=unixfrom, linesep='\r\n') return fp.getvalue() comment:22 Changed 4 years ago by What I don't understand is why this is only an issue with Python3, this should be a problem on every Python version -- or did I missread that report somehow. comment:23 Changed 4 years ago by @augustin: The easiest way is to inject it when we instanciate the Generator. But I'm wondering if it wouldn't be safer to set it on the message, to avoid the same kind of bugs in other code paths. Yes, but policy objects are relatively new (as is the linesep argument), so this would only work on python 3.3 onwards. So essentially we'd have to fix it in both instances. comment:24 Changed 4 years ago by Oh, I found something else: -- so for a sendmail backend we should probably use LF instead of CRLF? If that is indeed the case, this might get a bit ugly. comment:25 Changed 4 years ago by @apollo13 > I can't make the test for the moment (probably in about 10 hours) Everybody : It's look like IMF packet require CRLF and only US-ASCII in the header and in the body.

There is no way to know how this should get encoded for wire transfers (especially if you have multipart mime messages). This is also the reason why it broke on python 3 in the first place cause it produced quoted printable mails. comment:28 Changed 4 years ago by about the "fix" I have to try (comment:21) adding linesep='\r\n' to flatten The doc of flatten says : Optional linesep specifies the line separator character used to terminate lines in the output. If specified it overrides the value specified by the Generatoror msg‘s policy. In the doc of email.message, I see the reference to the policy, and in the doc of policy, I can read there is a specific (and new?) policy for SMTP email.policy.SMTP including linesep set to \r\n Using Python without Django, the msg looks well formated (so with the good policy, or with a good policy hook?), but not with django. I can't really figure out why.. comment:29 Changed 4 years ago by Using Python without Django, the msg looks well formated (so with the good policy, or with a good policy hook?), but not with django. I can't really figure out why.. Can you provide the exact python code you are using? Cause by default the compat policy is used which certainly produces newlines and not CRLF. comment:30 Changed 4 years ago by comment:31 Changed 4 years ago by Sure, here is the code : import smtplib from email.mime.text import MIMEText msg = MIMEText('Body goes here') msg['Subject'] = 'Hello' msg['From'] = 'webmaster@xxxxxxxxxxxxxxxxxxxxxxxxxxxx' msg['To'] = 'xxxxxxxxxxxxxx@gmail.com' s = smtplib.SMTP('SSL0.OVH.NET', 587, timeout = 4000) s.login('webmaster@xxxxxxxxxxxxxxxxxxxxxxxxxxxx', 'xxxxxxxx') s.sendmail('webmaster@xxxxxxxxxxxxxxxxxxxxxxxxxxxx', ['xxxxxxxxxxxxxx@gmail.com'], msg.as_string()) s.quit() It seems, I could not use as_string() nor as_byte() as shown in this official exemple : import smtplib from email.mime.text import MIMEText fp = open(textfile, 'rb') msg = MIMEText(fp.read()) fp.close() msg['Subject'] = 'The contents of %s' % textfile msg['From'] = me msg['To'] = you s = smtplib.SMTP('localhost') s.send_message(msg) s.quit() -> Anyway the SMTP.sendmail part of the doc seems to be the most important to explain our issue : SMTP.sendmail(from_addr, to_addrs, msg, ...) The required arguments are ..., and a message string. msg may be a string containing characters in the ASCII range, or a byte string. A string is encoded to bytes using the ascii codec, and lone \r and \n characters are converted to \r\n characters. A byte string is not modified. -> A byte string is not modified. That seems to expain why it works with python and not with the Django code. So it seems to be not because of the policy but because of the "byte string" transmitted to the sendmail function. comment:32 Changed 4 years ago by Good catch, I found the relevant snippets in the python 2.7 codebase too, so all we need is to fix bytes on Python3.x for SMTP. Reading the php bug I linked, I think the best solution is to fix this just for the SMTP backend. comment:33 Changed 4 years ago by New patch: diff --git a/django/core/mail/backends/smtp.py b/django/core/mail/backends/smtp.py index 4c41eb8..620168e 100644 --- a/django/core/mail/backends/smtp.py +++ b/django/core/mail/backends/smtp.py @@ -120,7 +120,7 @@ class EmailBackend(BaseEmailBackend): for addr in email_message.recipients()] message = email_message.message() try: - self.connection.sendmail(from_email, recipients, message.as_bytes()) + self.connection.sendmail(from_email, recipients, message.as_bytes(linesep='\r\n')) except smtplib.SMTPException: if not self.fail_silently: raise diff --git a/django/core/mail/message.py b/django/core/mail/message.py index da9891f..63b0014 100644 --- a/django/core/mail/message.py +++ b/django/core/mail/message.py @@ -123,7 +123,7 @@ def sanitize_address(addr, encoding): class MIMEMixin(): - def as_string(self, unixfrom=False): + def as_string(self, unixfrom=False, linesep='\n'): """Return the entire formatted message as a string.

How to manage language and region (Windows Store apps using JavaScript and HTML) You can control how Windows selects UI resources, and formats the UI elements of the app. To control these features, use the various language and region settings provided by Windows. For a sample app that demonstrates how to manage language and region settings, see Application resources and localization sample. A Windows user doesn't need to choose just one language from a limited set of languages. Instead, the user can tell Windows that they speak any language in the world, even if Windows itself isn't translated into that language. The user can even specify that they can speak multiple languages. A Windows user can specify their location, which can be anywhere in the world. Also, the user can specify that they speak any language in any location. The location and language do not limit each other. Just because the user speaks French doesn't mean they are located in France, or just because the user is in France doesn't mean they prefer to speak French. A Windows user can run apps in a completely different language than Windows. For example, the user can run an app in Spanish while Windows is running in English. For Windows Store apps, a language is represented as a BCP-47 language tag. Most APIs in the Windows Runtime, HTML, and XAML can return or accept string representations of these BCP-47 language tags. See also the IANA list of languages. To see a list of the language tags specifically supported by the Windows Store, see Choosing your languages. Instructions Step 1: Set the user language preferences. The user language preferences list is an ordered list of languages that describe the user's languages in the order that they prefer them. The user sets the list in Control Panel > Clock, Language, and Region > Language. The user's language preferences list can contain multiple languages and regional or otherwise specific variants. For example, the user might prefer fr-CA, but can also understand en-GB. Step 2: Specify the supported languages in the app's manifest. An app developer specifies the list of supported languages in the Resources element of the app's manifest file (typically Package.appxmanifest), or Visual Studio automatically generates the list of languages in the manifest file based on the languages found in the project. The manifest should accurately describe the supported languages at the appropriate level of granularity. The languages listed in the manifest are the languages displayed to users in the Windows Store. Step 3: Specify the default language. An app uses the default language when it doesn't support any of the languages that the user has chosen in the Languages control panel. MSBuild and MakePRI.exe use the default language to add metadata to assets marked in that language, enabling the appropriate assets to be chosen at runtime. To use Visual Studio to set the default language in a Windows Store app using JavaScript project: - Open package.appxmanifest in Visual Studio, go to the Application UI tab, and set your default language to the language you are using to author your application. The default language property must also be set as the first language in the manifest to appropriately set the application language (described in the step "Create the application language list", below). Resources in the default language must still be qualified with their language (for example, en-US/logo.png). The default language does not specify the implicit language of unqualified assets. To learn more, see How to name resources using qualifiers. Step 4: Qualify resources with their language. Consider your audience carefully and the language and location of users you want to target. Many people who live in a region don't prefer the primary language of that region. For example, there are millions of households in the United States in which the primary language is Spanish. When you qualify resources with language: - Include script when there is no suppress script value defined for the language. See the IANA subtag registry for language tag details. For example, use zh-Hant, zh-Hant-TW, or zh-Hans, and not zh-CN or zh-TW. - Mark all linguistic content with a language. The default language project property is not the language of unmarked resources (that is, neutral language); it specifies which marked language resource should be chosen if no other marked language resource matches the user. Mark assets with an accurate representation of the content - Windows does complex matching, including across regional variants (such as en-US to en-GB), so applications are free to mark assets with an accurate representation of the content and let Windows match appropriately for each user. - The Windows Store displays what's in the manifest to users looking at the application. - Be aware that some tools and other components such as machine translators may find specific language tags, such as regional dialect info, helpful in understanding the data. - Be sure to mark assets with full details, especially when multiple variants are available. For example, mark en-GB and en-US if both are specific to that region. - For languages that have a single standard dialect, there is no need to add region. General tagging is reasonable in some situations, such as marking assets with ja instead of ja-JP. Sometimes there are situations where not all resources need to be localized. - For resources such as UI strings that come in all languages, mark them with the appropriate language they are in and make sure to have all of these resources in the default language. There is no need to specify a neutral resource (one not marked with a language). - For resources that come in a subset of the entire application's set of languages (partial localization), specify the set of the languages the assets do come in and make sure to have all of these resources in the default language. Windows picks the best language possible for the user by looking at all the languages the user speaks in their preference order. For example, not all of an app's UI may be localized into Catalan if the app has a full set of resources in Spanish. For users who speak Catalan and then Spanish, the resources not available in Catalan appear in Spanish. - For resources that have specific exceptions in some languages and all other languages map to a common resource, the resource that should be used for all languages should be marked with the undetermined language tag 'und'. Windows interprets the 'und' language tag in a manner similar to '', in that it matches the top application language after any other specific match. For example, if a few resources (such as the width of an element) are different for Finnish, but the rest of the resources are the same for all languages, the Finnish resource should be marked with the Finnish language tag, and the rest should be marked with 'und'. - For resources that are based on a language's script instead of the language, such as a font or height of text, use the undetermined language tag with a specified script: 'und-<script>'. For example, for Latin fonts use und-Latn\fonts.css and for Cyrillic fonts use und-Cryl\fonts.css. Step 5: Create the application language list. At runtime, the system determines the user language preferences that the app declares support for in its manifest, and creates an application language list. It uses this list to determine the language(s) that the application should be in. The list determines the language(s) that is used for app and system resources, dates, times, and numbers, and other components. For example, the Resource Management System (Windows.ApplicationModel.Resources, Windows.ApplicationModel.Resources.Core and WinJS.Resources Namespace) loads UI resources according to the application language. Windows.Globalization also chooses formats based on the application language list. The application language list is available using Windows.Globalization.ApplicationLanguages.languages. The matching of languages to resources is difficult. We recommend that you let Windows handle the matching because there are many optional components to a language tag that influence priority of match, and these can be encountered in practice. Examples of optional components in a language tag are: - Script for suppress script languages. For example, en-Latn-US matches en-US. - Region. For example, en-US matches en. - Variants. For example, de-DE-1996 matches de-DE. - -x and other extensions. For example, en-US-x-Pirate matches en-US. There are also many components to a language tag that are not of the form xx or xx-yy, and not all match. - zh-Hant does not match zh-Hans. Windows prioritizes matching of languages in a standard well-understood way. For example, en-US matches, in priority order, en-US, en, en-GB, and so forth. - Windows does cross regional matching. For example, en-US matches en-US, then en, and then en-. - Windows has additional data for affinity matching within a region, such as the primary region for a language. For example, fr-FR is a better match for fr-BE than is fr-CA. - Any future improvements in language matching in Windows will be obtained for free when you depend on Windows APIs. Matching for the first language in a list occurs before matching of the second language in a list, even for other regional variants. For example, a resource for en-GB is chosen over an fr-CA resource if the application language is en-US. Only if there are no resources for a form of en is a resource for fr-CA chosen. The application language list is set to the user's regional variant, even if it is different than the regional variant that the app provided. For example, if the user speaks en-GB but the app supports en-US, the application language list would include en-GB. This ensures that dates, times, and numbers are formatted more closely to the user's expectations (en-GB), but the UI resources are still loaded (due to language matching) in the app's supported language (en-US). The application language list is made up of the following items: - (Optional) Primary Language Override The PrimaryLanguageOverride is a simple override setting for apps that give users their own independent language choice, or apps that have some strong reason to override the default language choices. To learn more, see the Application resources and localization sample. - The user's languages supported by the app This is a list of the user's language preferences, in order of language preference. It is filtered by the list of supported languages in the app's manifest. Filtering the user's languages by those supported by the app maintains consistency among software development kits (SDKs), class libraries, dependent framework packages, and the app. - If 1 and 2 are empty, the default or first language supported by the app If the user doesn't speak any languages that the app supports, the chosen application language is the first language supported by the app. See the Remarks section below for examples. Step 6: Set the HTTP Accept Language header. HTTP requests made from Windows Store apps and Desktop apps in typical web requests and XMLHttpRequest (XHR), use the standard HTTP Accept-Language header. By default, the HTTP header is set to the user's language preferences, in the user's preferred order, as specified in Control Panel > Clock, Language, and Region > Language. Each language in the list is further expanded to include neutrals of the language and a weighting (q). For example, a user's language list of fr-FR and en-US results in an HTTP Accept-Language header of fr-FR, fr, en-US, en ("fr-FR,fr;q=0.8,en-US;q=0.5,en;q=0.3"). Step 7: Use the APIs in the Windows.Globalization namespace. Typically, the API elements in the Windows.Globalization namespace use the application language list to determine the language. If none of the languages has a matching format, the user locale is used. This is the same locale that is used for the system clock. The user locale is available from the Control Panel > Clock, Language, and Region > Region: Change date, time, or number formats. The Windows.Globalization APIs also accept an override to specify a list of languages to use, instead of the application language list. Windows.Globalization also has a Language object that is provided as a helper object. It lets apps inspect details about the language, such as the script of the language, the display name, and the native name. Step 8: Use geographic region when appropriate. Instead of language, you should use the user's home geographic region setting for choosing what content to display to the user. For example, a news app might default to displaying content from a user's home location, which is set when Windows is installed and is available in the Region Control Panel. You can retrieve the current user's home region setting by using Windows.System.UserProfile.GlobalizationPreferences.HomeGeographicRegion. Windows.Globalization also has a GeographicRegion object that is provided as a helper object. It lets apps inspect details about a particular region, such as its display name, native name, and currencies in use. Remarks The following table contains examples of what the user would see in the app's UI under various language and region settings.	http://msdn.microsoft.com/en-us/library/hh967758.aspx	CC-MAIN-2014-10	refinedweb	2,244	54.32
Details Description If. Activity Created reviewboard Thanks for patch v7. A couple of more comments. 70. There is a long standing bug in ProducerRequest.handleError(). If ack=0, we shouldn't send a response when the broker hits an unexpected error. We should either close the socket connection or send no response. Not sure which one is better. 71. A minor issue. The following comment in RequestChannel is a bit confusing. It sounds like that it needs to read more data from network to complete this request, but it is not. /** No operation to take for the request, need to read more over the network */ def noOperation(processor: Int, request: RequestChannel.Request) { Committed patch v7 to 0.8 after making the logging fix described above This is great. +1. One improvement on logging - info(("Send the close connection response due to error handling produce request " + "[clientId = %s, correlationId = %s, topicAndPartition = %s] with Ack=0") .format(produceRequest.clientId, produceRequest.correlationId, produceRequest.topicPartitionMessageSizeMap.mkString("[",",","]"))) Here we only want to print the topic and partition, so it seems that we should be printing the keys of the map, not the entire map ? produceRequest.topicPartitionMessageSizeMap.keySet.mkString(",") I can make this change on checkin. Thanks for the comments, Neha, Jay. Neha: 1. Done. 2. Incorporated with Jay's comments. Jay: 1. Done. 2. Done. I ended up using trait and objects, and let requestChannel.close and requestChannel.noOperation (I changed the name from noResponse here since it matches the noOpAction better) create new responses themselves. 3. Done. 4. Done. 5. Done. Regarding your question, the message loss is depending on the producer throughput and queue size. Since the first message will always be silently dropped, and once the producer noticed the socket closure, it will stop producing and refresh new metadata, and if during this time the producer queue is full then it will drop more messages. So the answer would be the range between [1, produce-throughput / time-taken-to-refresh-metadata - queue-size]. Great fix. A few minor comments, mostly stylistic. RequestChannel.scala: 1. This usage exposes a bit much: requestChannel.sendResponse(new RequestChannel.Response(request.processor, request, null, RequestChannel.CloseSocket)) I think it might be nicer to have this instead: requestChannel.close(request.processor, request) and requestChannel.noResponse(req.processor, request) Implementation would be the same, it just would just be a little more clear for the user and the response codes can be private. Likewise in the response object I should be able to 2. These are a little confusing: val SendResponse: Short = 0 val NoResponse: Short = 1 val CloseSocket: Short = 9 Why is it 0, 1, and 9? What is the relationship between these and ErrorMapping? It should be clear from reading. Is there a reason we can't use a case class case class ResponseAction case object SendAction extends ResponseAction case object NoOpAction extends ResponseAction case object CloseConnectionAction extends ResponseAction Then to use it response.action match{ case SendAction => do send case NoOpAction => read more case CloseConnectionAction => something } This seems clearer to me and I don't think it is significantly more expensive. Can we also standardize the usage so that we no longer have the user EITHER give null or NoResponse? It should be one or the other. 3. This logging "Cancelling the request key to notify socket server close the connection due to error handling produce request " is not informative to the user. What does it mean to cancel a key? What broke? What should they do? I also think this should be info unless we want the server admin to take some action (I don't think so, right? This is a normal occurance). SocketServer.scala 4. The comment "a null response send object" is retained but we are no longer using null to indicate this we are using RequestChannel.NoResponse. I think this comment is actually a little verbose given that we now have a nicely named response action. ProducerTest.scala: 5. org.scalatest.TestFailedException: Is there a reason you are giving the full path here instead of importing it Question on testing, what is the message loss rate with acks=0 under moderate load if we do something like a controlled shutdown with other replicas available? I like the way the responseCode is generalized. Patch v6 looks good, few minor comments before checkin - 1. Remove unused variable allBrokers from KafkaApis 2. This comment needs to be changed according to the new response code logic - // a null response send object indicates Maybe we should wait for review from Jay Kreps since he has most context on the socket server. After talking around with people I now proposed an approach similar to v4 but generalized with a responseCode instead of just a close socket flag. And on SocketServer the processor would act based on the code instead of checking if the responseSend is null or not. Also change aliveBrokers in KafkaApis from var to val since it is not overwritten in lifetime. Thanks for the comments Neha. 1.1. Great point. The only concern is that now KafkaApis need to know that requestKey is actually java.nio.channels.SelectionKey. But I think this is fine. 1.2. Done. Thanks for the patches, Guozhang. I reviewed patch v4 and here are some comments - KafkaApis and SocketServer 1.1 One way to allow the socket server to close the channel is to just mark the request's key cancelled in the Response object. This way when the socket server is handling the response, it will throw a CancelledKeyException and we close the key in this case. One advantage of this approach is we can avoid introducing the close socket flag, just to handle this case. To make sure the request metrics are always updated, we can move curr.request.updateRequestMetrics to the first statement in the (curr.responseSend == null) block. 1.2 I think the below warn message can be improved - Sending the close socket signal due to error handling produce request [%s] with Ack=0 Let's include the client id, correlation id and list of topics and partitions that this request had. This is probably more useful than printing the entire produce request as is, since that attempts to print things like ByteBufferMessageSet and is unreadable. Thanks for the comments Jun. 30. Done. 31. After a second thought I realized that we do not need to sleep since the second message size is large enough to cause the socket buffer to flush immediately, and by then the socket close should have been triggered by the server. This has been verified in the unit test. Made some minor changes on comments and rebased on 0.8 Magnus, thanks for your comment. What you suggested is interesting and could be a more effective way of communicating between the producer and the broker. It does require that the producer be able to receive requests initiated at the broker. We do plan to make the producer side processing selector based for efficiency reason. However, this will be a post 0.8 item. We could consider your suggestion then. Regarding your concern about dropped messages, my take is the following. If a client chooses not to receive an ack, it probably means that losing a few batch of messages is not that important. If a client does care about data loss, it can choose ack with 1 or -1. The throughout will be less. However, there are other ways to improve the throughput (e.g., using a larger batch size and/or more instances of producers). Guozhang, patch v3 looks good to me overall. A few more comments: 30. SyncProducerTest.testMessagesizeTooLargeWithAckZero(): You hardcoded the sleep to 500ms. Could you change it to the waitUntil style wait such that the test can finish early if the conditions have been met? 31. KafkaApi.handleProducerRequest(): The logging should probably be at debug level since this doesn't indicate an error at the broker. It's really an error for the client. Hi Guozhang, I understand that you might not want to introduce a new message semantic at this point of the 0.8 beta, but it wont get easier after the release. My proposal is a change of the protocol definition to allow unsolicited metadata response messages to be sent from the broker, this would of course require changes in most clients, but a very small one for those that are not interested in keeping their leader cache up to date. Consider a producer forwarding >100kmsgs/s for a number of topics to a broker that suddenly drops the connection because one of those topics changed leader, the producer message queue will quickly build up and might start dropping messages (for topics that didnt loose their leader) due to local queue thresholds or very slowly recover if the current rate of messages is close to the maximum thruput. In my mind closing the socket because one top+par changed leader is a very intrusive way to signal an event for sub-set of the communication, and it should instead be fixed properly with an unsoliticed metadata response message. The unsolicited metadata response message is useful for other scenarios aswell, new brokers and topics being added, for instance. My two cents on the topic, thank you. Hello Magnus, 1. Under Ack=0, the producer does not expect any responses for produce request, and it does not listen to any possible connections from the producer either. So actively sending MetadataResponse would not work: producers are only expecting MetadataResponse when they send MetadataRequest. 2. When we close the socket, producer would be notified and try to refresh their Metadata and retry. Since by default each produce request will be retried multiple times before it is got dropped, the current approach would not cause lost messages. If the producer is sending messages through the same broker for other topic+partitions that did not have a leader change they will also be affected by the close of the socket, resulting in lost messages. It would be better if the broker would notify all connected clients of broker changes (leader change, broker add/delete, topic add/delete) by sending an unsolicited MetadataResponse message (with corrid 0) (or by some other mean). This would propogate topology changes in a faster and less intrusive way. Add the testMessageSizeTooLargeWithAckZero to syncProducerTest, which: 1. First send a large message that will cause the MessageSizeTooLarge exception, and hence close the socket. But this message will be silently dropped and lost. 2. Then send another large message, but just to make sure its size exceeds the buffer size so the socket buffer will be flushed immediately; this send should fail since the socket has been closed. Sorry for the name misleading, I did not shut down the broker but instead send a large message to it to trigger the MessageSizeTooLargeException. The name of the test should be testSendTooLargeMessageWithAckZero. I will use SyncProducer instead of Producer in this test, and send a normal message to the broker after this message, and expecting it to fail due to socket IO exception. Thanks for patch v2. Some more comments. 20. testSendWithAckZeroDeadBroker(): I am not sure if the unit test does what you want. First of all, setup() will always start brokers for each test unless you explicitly shut them down. So, in this test, the brokers are not dead. Second, the test doesn't really test that the socket is closed after error. I suggest that we add a new test in SyncProducerTest. We send a request with ack=0 with a large message. After that, we can try to send a new request again and we should hit a socket I/O exception. We may have to wait for some time between the two requests. Thanks for the comments Jun. 1,2,3. Done. Thanks for the patch. Some comments: 1. SocketServer: We should call updateRequestMetrics even when we close the socket. Otherwise, total time will be broken for that request. 2. ProducerTest: Let's add a new unit test instead of piggybacking on the existing one. What we can do is to create a sync producer and send a produce request with ack=0 that will introduce an error (e.g., a message larger than max size). After that, we can verified that the underlying socket is closed. 3. KafkaApi: In the debug logging, why not log the whole producer request? Add one case for ack=0 in testSendWithDeadBroker, passed. Following the close-socket approach, I propose the following change: 1. Add a closeSocket: Boolean field in Response class. 2. In KafkaApi.handleProducerRequest, if requireAck == 0 check if numPartitionsInError != 0. If yes set closeSocket to true in the returning response. 3. SocketServer.Processor.processNewResponses, if curr.responseSend == null, check if closeSocket == true. If yes, log the closing socket info and close the key. It seems there are various ways that can cause this to happen. (a) In the above scenario, after the leaders fail over, topicX causes new sockets to be established. Then topicY uses the newly established socket without realizing that the leader for topic Y has changed. (b) When we fetch the metadata for a topic, we fetch the metadata for all partitions. Let's say that we never get to send any data to a particular partition. The socket for this partition is not established since SyncProducer make socket connections lazily on first send. Then the leader for the partition changes. Finally, the producer sends a message to that partition. Now a socket is established to the wrong leader without the producer realizing it. In general, if we hit any error for produce requests with ack=0, currently the producer won't notice it. For example, if the broker hits a MessageTooLargeException or if the broker hits any other unexpected exceptions. In those cases, forwarding the requests will not help. Also, forwarding requests will complicate the logic in the broker since we have to figure out the broker's host and port, and potentially cache the socket connection to other brokers. An alternative solution is to simply close the socket connection when we hit any error for produce requests with ack=0. This way, the producer will realize the error on next send. Here's a related scenario, that I see after a rolling restart of my brokers (using ack=0). looking back at my logs, I'm wondering if a producer will reuse the same socket to send data to the same broker, for multiple topics (I'm guessing yes). In which case, it looks like I'm seeing this scenario: 1. producer1 is happily sending messages for topicX and topicY to serverA (serverA is the leader for both topics, only 1 partition for each topic for simplicity). 2. serverA is restarted, and in the process, serverB becomes the new leader for both topicX and topicY. 3. producer1 decides to send a new message to topicX to serverA. 3a. this results in an exception ("Connection reset by peer"). producer1's connection to serverA is invalidated. 3b. producer1 makes a new metadata request for topicX, and learns that serverB is now the leader for topicX. 3c. producer1 resends the message to topicX, on serverB. 4. producer1 decides to send a new message to topicY to serverA. 4a. producer1 notes that it's socket to serverA is invalid, so it creates a new connection to serverA. 4b. producer1 successfully sends it's message to serverA (without realizing that serverA is no longer the leader for topicY). 4c. serverA logs to it's console: 2013-06-23 08:28:46,770 WARN [kafka-request-handler-2] server.KafkaApis - [KafkaApi-508818741] Produce request with correlation id 7136261 from client on partition [mytopic,0] failed due to Leader not local for partition [mytopic,0] on broker 508818741 5. producer1 continues to send messages for topicY to serverA, and serverA continues to log the same messages. 6. 10 minutes later, producer1 decides to update it's metadata for topicY, and learns that serverB is now the leader for topidY. 7. the warning messages finally stop in the console for serverA. I am pretty sure this scenario, or one very close to it, is what I'm seeing in my logs, after doing a rolling restart, with controlled shutdown. I think this scenario makes the issue more severe than just a problem with controlled restart and ack=0. Thanks for the followup patch. +1 and committed to 0.8.	https://issues.apache.org/jira/browse/KAFKA-955?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel	CC-MAIN-2014-15	refinedweb	2,740	64.71
HTML 5 Takes Aim At Flash and Silverlight 500 snydeq writes "While Adobe, Microsoft, and Sun duke it out with proprietary technologies for implementing multimedia on the Web, HTML 5 has the potential to eat these vendors' lunches, offering Web experiences based on an industry standard.

I'm a coding newb and want to learn some more java. I'm currently taking an introductory programming course in high school and am just trying to play around outside of class. This program I'm creating is supposed to print out a few instructions and questions in the console, to which I want to retrieve user input using a scanner and variable. The goal of the program is for the user to be able to create a 'drawing' based on pure instinct, then this drawing is displayed after the fact. Here's my problem. I'm asking the user and storing the information in variables that are native to the main method, but I need to use this information in the paintComponent method. I tried adding static in front of the variable such as: static int emptyRectW1 = kboard.nextInt(); import java.util.Scanner; import java.awt.Graphics; import java.awt.Color; import java.awt.Container; import javax.swing.JFrame; import javax.swing.JPanel; public class BlindDrawing extends JPanel { public static void main (String[] args) { Scanner kboard = new Scanner(System.in); System.out.println("Welcome to the Blind Drawing Game!"); System.out.println("In this game, you will be asked questions about how to construct an image using rectangles and ovals. You will be asked the shape's dimensions and position.

asked 2018-10-19 04:29:29 -0600 updated 2018-10-20 10:36:04 -0600 Since the solutions of a SAT formula corresponds to integer points of some polytope, you can solve #SAT by asking Sage to construct that polytope and count its integer points. See the code below. The default integral_points_count for rational polytopes basically enumerates all integer points, so the choice of the backend could have an importance on the speed. I bet normaliz will be faster, it requires the pynormaliz optional package to be installed. Please report about your real-life experiments. Also, the latte_int optional package could speed things in some cases, please report your experiments, since that could depend on the actual problem (on the code below, you should use latte=True to use it). That said for further improvements, we really need to know your real problem. Typically, the polytopes we consider are included in the unit cube of large dimension, hence I do not see how Barvinok theory (which is what latte_int relies on) could speed things up since no set of >=3 points is aligned. So, depending on your problem, one could imagine to describe it with a "fatter" polytope of smaller dimension, whithout reducing it to SAT first, so that Barvinok theory could be much more efficient. Other approaches could be thought about too. For example, given a SAT formula, it is easy to enumerate all solution with a SAT solver: for each solution, add its "opposit" as a new constraint and solve it again. I have plans to add such an __iter__ method to the current SAT solvers in Sage. def sharp_sat(clauses, backend='cdd', latte=False): r""" Count the number of solutions of the given CNF formula.

I assume you know that the fairly recent movie "When a Stranger Calls" is a re-make of the 1979 original which starred Carol Kane as the babysitter. You may remember Carol Kane as Simka, Latka Gravas' (Andy Kaufman) wife in the TV show Taxi. Andy's dead now you know...sad really...he kind of went off the deep end when he started wrestling women... Blog reader: What the hell are you talking about?

Okay, I'm better now. So anyway, I wanted to give you a heads up that there is a breaking change coming in the Crossbow API for Beta2. There used to be a Children property on WindowsFormsHost control. You would use the property to add your subsequent Windows Forms control to the host via the Children.Add() method. We'll it ain't there anymore. We replaced it with a Child property. This was done because we felt it was kinda stupid to have a collection property that limited you to one item. (You may remember that even though we implemented this property as a collection, we enforced a limitation of a single item in the collection). So now there's just the single Child property and you simply assign some Windows Forms control to it. Likewise on the ElementHost control, we used to have the Controls collection property where you added your single top-level element. Now we have replaced that with a Child property as well. Once again, we just wanted to remove the collection and replace it with a singleton and maintained consistency with the naming. Note that this change goes into effect in the Beta2 drop of Crossbow. <ManiacalVoice>So next time when the compiler calls and tells you something's wrong...remember to check the children...</ManiacalVoice> Have..." I just wanted to make sure eveyone was aware of this little fact. First of all, in more recent builds (at leas the Feb CTP and beyond) you no longer use Mapping PIs to reference external assemblies. Instead, you simply use the xmlns attribute by itself. So using "old school" syntax you would have something like: <? Now you would loose the Mapping PI altogether and just use the xmlns attribute in the following manner: Furthermore, you do not need to do this at all for the things in WindowsFormsIntegration such as WindowsFormsHost. These are now part of the standard schema and no longer need to be prefixed. I have received numerous emails from people who are using the Feb CTP version of Crossbow and have run into the bug that we have in ElementHost where the hosted WPF content does not show up until you resize the Form that contains the ElementHost control. While this may be a small enough issue, many people have requested a work-around for the problem. Well, you would think that all you have to do is force a repaint by calling Invalidate() or Refresh() on the Form, but alas this does not make the content appear. So how can we fix this? Don't fret my little Crossbow consumers...Uncle Mike is here to hook you up. Here's what you need to do...At the end of your Form_Load() event handler, hook the Shown event and change the Form's size. So, something like: This little hack will at least get you up and running so that you can see your hosted WPF content when the Form loads. Generally, this will suffice until you get the version of Crossbow that has this fixed. Okay). As I typed the title to this post, I wondered just how many people over the years have butchered "Billy the Bard"'s line from Romeo & Juliet? I'm sure it's ridiculously high and here I go contributing to it. Sorry about that Bill, you can roll back over in your grave now... In the spirit of interoperability, I thought it may be interesting to take a look at a scenario where you want to write a WPF application that uses resources that are entered and stored via the Resource Editor in Visual Studio. Let's create a cheesy little application that shows off how to do this. First we need to create a WPF application using VS. Then we add some resources using the Resource Editor. To do that we just go over to our Solution Explorer in VS, expand the Properties node and double-click on 'Resources.resx'. This will launch the Resource Editor. In the Resource Editor, let's add a string resource and an image resource. For the string, we will use some lyrics to one of my favorite Soul Coughing songs 'Screenwriters Blues'. Since we are using these lyrics, let's use the image of the 'Ruby Vroom' CD that the song is on as our resource image. Okay, now that we have our resources stored, let's work on the rest of the app. Let's go to our XAML and add a Button and a Label. What we are going to do is use the string from our resources for the Label and use the image as the background of our button. Now using the string is perfectly straight forward since a string is a string. The bitmap however is a horse of a different color or it smells different or something. (Yeah, I know...I'm mixing my metaphors). So let's go to the code behind to start doing our thing. We need to figure out where we are going to put our logic to set the label and the button. Usually you do this in some event handler in the code behind so we'll do that as well. However, what event should we choose?Most of the time you see examples using the Loaded event for the Window so that would be normal for us to use as well. BUT, I ain't gonna do that. Why? Well, it's because I want to be different and it's a good habit to get into. Let me explain this a bit. Many times in our code behind, we are doing things like adding controls to our visual tree in a WPF application. And if we use the Loaded event handler for doing this, we can sometimes get undesireable results. For example, if we are using a parent control such as a StackPanel and if we were to handle the Loaded event and put logic there to add controls, you would see that the Loaded event fires more than once due to the re-layout of the window after each control is added. This would result in having the controls added multiple times. If we instead use the SourceInitialized event, we don't have this problem because it is fired only once. Okay, in our code behind let's handle the SourceInitialized event and put our code there. The first thing we want to do is get our resources. Next let's do set our label's content to be the value in our string resource. Now comes the part that's just a bit trickier...setting our button's background to our resource image. It's only tricky because the resource happens to be of type System.Drawing.Bitmap and we cannot set our button's background to a System.Drawing.Bitmap. To do this, we have to convert the bitmap to something that WPF understands. Luckly, there is a helper function that makes this a bit easier. The helper function is called 'CreateBitmapSourceFromHBitmap' which can be found in the System.Windows.Interop.Imaging namespace. Let's take a quick look at the function signature for this function: public static BitmapSource CreateBitmapSourceFromHBitmap ( IntPtr bitmap, IntPtr palette, Int32Rect sourceRect, BitmapSizeOptions sizeOptions ) The first parameter is a pointer to our original bitmap as an HBITMAP. In order to supply that we have to call the GetHBitmap() function on our System.Drawing.Bitmap object. The next parameter is a pointer to the bitmap's palette. Now we have a Palette property on our original bitmap object, but we can't pass it to this function because the function wants the palette as an IntPtr. So to make this happen, you are going to have to write some magic code that will convert the color palette to an IntPtr. (Actually, I tried this and never quite got it right). But the good news is that since our bitmap does not have a specific palette, we can just pass in IntPtr.Zero (null). Next is the source rectangle for our bitmap. Note that the function want this to be in the form of an Int32Rect and not a System.Drawing.Rectangle object. I don't totally understand what the final parameter is all about, but I played around with different settings and managed to get this working so I didn't worry about it too much. Okay, now that we have converted our bitmap to something that we can use, let's set the background of our button to the image and make sure the size of the button is the proper size. Okay, now let's run the app and see what it looks like: Okay, just what we wanted huh? Okay, now I'm really going to show my age... If you're an old fart like me you remember the classic Cracker Jack commericals featuring character actor Jack Gilford where he succumbs to pressure from little kids to share his Cracker Jacks and the tag line was "Sharing...". Okay so you don't remember huh? Anyway...the point of all of this is to talk about what else...sharing. Specifically I want to talk about a Crossbow scenario where you may have a Windows Forms application that contains multiple ElementHost controls that each contain some WPF content and you want to use shared resources such as styles. So here's the deal...In a standard WPF application you usually hang resources off of some parent element and in doing so, child element will inherit these resources. For example, say that we want all Labels in a WPF application to have a certain look. To acheive this we would do something like this: This will define the style for all Labels that are children of the StackPanel. So all Labels that are added to the StackPanel will all inherit the style so that they all look the same. Yeah, so... Well the issue here is that say we have a Windows Forms application that contains some WPF content and you want to be able to create "global" styles for your elements. Furthermore, you may have multiple instances of this or other WPF content spread across your Windows Forms application and you want them to all share common styles. How do you do it? The problem is that you don't have the ability to have application level XAML file (MyApp.xaml) where you could define global styles. Well, it's really not difficult, you just have to know how to wire it all up. So here's the deal... What you need to do is simply create a global ResourceDictionary to hang your global styles off of and then point all of your hosted WPF content to that ResourceDictionary. Let's take a look at this in more detail. Say we have a WPF UserControl that consists of multiple Labels. (Yeah, I know...it's totally contrived and you would never build something so stupid, but bear with me it's just for illustrative purposes). So the XAML for your UserControl may look something like: Now suppose that we want to host this content on a Windows Form form multiple times and we want to globally define how the labels in the UserControls should look and we want each instance of the UserControl to have the same look. So let's host two instances of the UserControl on a Windows Form form using a SplitContainer to separate the two. To do this, we need to first create the form and then drop a SplitContainer on the form. Then we will put two ElementHost controls (one on each SplitterPanel). Now, to make this easy for us to do, we're going to put the ElementHost control onto our Toolbox so that it will be easier for us to work at design time. To do this, right-click on the ToolBox and pick 'Choose Items...' Then you will see the 'Choose Toolbox Items' dialog box. Here you will need to click the 'Browse' button to find the WindowsFormsIntegration dll that contains ElementHost. Assuming that you are using the Feb CTP of Crossbow, you will find the dll in the Cider directory. Next you will see the ElementHost control in the 'Choose Toolbox Items' dialog box. Check the check box for the ElementHost control and click the OK button. Now you should see the ElementHost control in the Toolbox. Whew, you probably already knew how to do that anyway, but what the hell... Now that we have the ElementHost control on our Toolbox, let's put this thing together. Let's drop a SplitContainer on our Form. Next we will put an ElementHost control on each of the panels of the SplitContainer. Just drag and drop an ElementHost on each from the Toolbox. Now, you will notice that the ElementHost gets rendered with its background color the same as the panels and without any borders. This makes it look as though it's invisible once it is not selected. If it bugs you that you cannot see the ElementHost when it is not selected, just set its background color to something else. Okay, next lets select each ElementHost control and Dock Fill them so that they take up all the real estate of each panel. Now we can put our WPF UserControls on the form by hosting them in each ElementHost. Let's do this by going to the code behind in say the Form_Load event handler to do this. Run the app and it should look something like: Now we want to introduce our global Label style so that both instances of the UserControl uses the style for all of the labels. We do this by creating a global ResourceDictionary and adding a style to it. Now we just need to point our UserControls to the ResourceDictionary object: Let's run the app and see what happens now... Sweet! Now all of the WPF labels in our Windows Forms application share the same style. Okay, I bet you are saying: "Hey, you could've just added that style to the definition of the UserControl in XAML and each instance of the UserControl in the app would share the Label's style". Yep, in this particular case you're right. However, what if the two instances of the UserControl were in fact two different UserControls for example. In that case, I would have had to define the style in both XAML files. This way I only have to define the style once in code behind and wire-up any WPF content to that style.. Well my MSDN TV debut finally hit the airwaves. I teased you a while back when I told you that it was coming (I didn't realize that it took so long for these to make it to the site). I know you have been just trembling with anticipation, but tremble no more 'cause it here! Y'know they tell you that you look 10 pounds heavier when you are on camera? Wow, how many cameras were on me anyway? (Okay, I know, I stole that from a Friends episode) Enjoy! Hello! I recently did an interview with Scott Swiggart on the subject of Crossbow and the article ended up on Dr. Dobbs, check it out: I also did an MSDN TV segment, but it's not posted yet, but keep an eye out for it () Yikes, you mean the last time I posted something on my blog was on Halloween? Geez, I'm really sorry about that and I'll try to make it up to you...really I will. You see, there's a few reasons why I've been delinquent in blogland lately... One reason is that I just got too excited and posted too frequently and used up all my good material and then I really didn't have anything interesting to say. The other reason is simply just being busy with stuff...then there's the holidays...you know how it goes. But I'm back and I'll do my best to provide some useful content. I'm already getting some ideas so stay tuned... I received an email from Keeron today and he was experiencing some difficulties in hosting an ActiveX control in a WindowsFormsHost which was parented to a Canvas in a WPF application. His basic problem seemed to be that the control simply was not showing up in the WPF application at all. So what's up with that? Let's start off by removing the ActiveX control from the equation since the issue isn't directly related to the ActiveX control, the issue exists for just standard Windows Forms controls as well. So let's assume we have a simply scenario where we want to host a Windows Forms button in a WPF application. Let's first consider hosting it in a Grid element then we will switch it to use a Canvas element. The code behind would look something like: private void WindowLoaded(object sender, RoutedEventArgs e){ WindowsFormsHost host = new WindowsFormsHost(); System.Windows.Forms.Button b = new System.Windows.Forms.Button(); b.Text = "WF Button"; host.Children.Add(b); this.grid1.Children.Add(host);} Run the app and everything works just fine. But now lets change the Grid element to a Canvas element... And change the code behind to reference the Canvas instead of the Grid: private void WindowLoaded(object sender, RoutedEventArgs e){ WindowsFormsHost host = new WindowsFormsHost(); System.Windows.Forms.Button b = new System.Windows.Forms.Button(); b.Text = "WF Button"; host.Children.Add(b); this.canvas1.Children.Add(host);} Run the app again and we don't see our button! What gives? Well, let's think about it just a second. Firstly, I neglected to indicate where in the canvas the button should go. Normally, you would do this is XAML as follows: But I'm working in code so I need to figure out how to do this using C#... Well the Canvas.Top and Canvas.Left properties are actually "attached properties" in WPF parlance and to set these using code you would use the SetValue() method on the object in question and then provide the property and value: private void WindowLoaded(object sender, RoutedEventArgs e){ WindowsFormsHost host = new WindowsFormsHost(); System.Windows.Forms.Button b = new System.Windows.Forms.Button(); b.Text = "WF Button"; host.Children.Add(b); host.SetValue(Canvas.TopProperty, 5.0); host.SetValue(Canvas.LeftProperty, 5.0); this.canvas1.Children.Add(host);} Cool, that should do it right? Let's give it a whirl... Doh! Still didn't work! Why not? Well, the issue is related to how the WPF layout engine works. The problem is that since we did not explicitly set the size of the WindowsFormsHost control, the layout engine thinks that it has a size of 0 and therefore does not layout the control properly. To fix this, we just need to give the WindowsFormsHost control an explicit size: private void WindowLoaded(object sender, RoutedEventArgs e){ WindowsFormsHost host = new WindowsFormsHost(); host.Height = 100; host.Width = 300; System.Windows.Forms.Button b = new System.Windows.Forms.Button(); b.Text = "WF Button"; host.Children.Add(b); host.SetValue(Canvas.TopProperty, 5.0); host.SetValue(Canvas.LeftProperty, 5.0); this.canvas1.Children.Add(host);} Now when we re-run the application, we will see our button.	http://blogs.msdn.com/mhendersblog/	crawl-002	refinedweb	3,380	72.26
DFS, Folder Redirection and Offline Files... - From: Gord Armstrong <GordArmstrong@xxxxxxxxxxxxxxxxxxxxxxxxx> - Date: Wed, 27 Jun 2007 20:52:01 -0700 Hello to all... We have a Windows 2003 domain, two w2k3 SP1 DCs, and my file server is w2k3 R2 SP1 Ent. All of our client machines are Windows XP SP2. We performed a Root Consolidation via the File Server Migration Utility and Root Consolidation wizard. I also have a Domain based DFS namespace. We performed the Root Consolidation for legacy reasons. Namely a ton of linked files on the old file server, as well as we didn't want to deal with the fun of moving users' home directories which included thier redirected My Documents and then having the client side caches go nuts. Our users have two mapped drives which point to DFS paths in the stand alone, consolidated, root. (\\retiredservername\share1 and \\retiredservername\share2\username) We use the Folder Redirection GPO to send the contents of clients' My Documents folder to \\retiredservername\share2\username\my documents. The My Documents folders have been allowed to be made available offline as the vast majority of our users are laptop based. That's the windup, here's the pitch. Since the Root Consolidation, and the creation of the Domain Based Namespace, we've had an issue where if laptop users, disconnect thier CAT5 cable, pick up thier laptop and walk into a meeting room, reconnect....and POW...they cannot access either of thier two mapped drives or thier My Documents folder. The only way to get the access back is to reboot, a log off/log on won't do it. We've seen a number of kb articles around this which mainly pertain to the combo of DFS, Folder Redirection and Offline files being unsupported in Windows 2000, but as we are completely Windows 2003, and the file server is R2 Enterprise to support the multiple roots, we are concerned. We have found if we take Offline Files out of the equation, by clicking on the 'caching' button in the share tab of the target folders, and removing the default selection of 'allow users to make files available offline' and set it to 'not available offline', we notice a vast improvement in the mapped drive disconnection issue. Of course, this solves one issue but cripples our laptop users as now they still get thier My Documents folders redirected, but now the content is not available when they are away from the Domain. The 'make available offline' and 'synchronize' options are now removed from the folder. Going into Explorer, folder options, synchronize, yields little results as users just get informed there are no selections available for synchronization. Has anyone else out there come across this and solved it? I suppose i could apply SP2 to the file server and see if by some luck it helps. Thoughts, comments, ideas? Thanks.

You can subscribe to this list here. Showing 5 results of 5 I was wondering about that as well. I've been fooling around with Android to get an idea what it is and if there is a way to avoid having to write Java when developing applications for it. The answer for this moment is 'no'. Although they use their own class libraries (similar to but different from SUN's), the Dalvik virtual machine and a bytecode fomat that differs from SUN's, they still stick to the Java syntax. And that is a bit disappointing in my eyes. Why not support a host of dynamic languages on top of the VM from the start? That would greatly increase the chances of Android if you ask me. Anyway, since Java (at least the syntax) is the only programming language on Android the only possible alternative, from Python's perspective, would be Jython. I know close to nothing about how Jython works internally (pointers welcome) and couldn't tell you if Jython can as easily be inplemented on top of Android's custom class libraries / the Dalvik VM. If it could, I'm sure it would create a killer environment for developers of mobile applications. Anybody here that can shed some light on this? 2B On 11/16/07, Beyonlo Beyonlo <beyonlo@...> wrote: > > Hey all, Jython run fine on android ? > If not, are there a effort to do that works ? > > Thanks, > > Beyonlo > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.

But I just did. The problem was posted to this list way back in 2004 and it involves using jythonc to deploy a jar with jfreechart. Something like: jythonc -A org.jfree -d -j yourjar.jar myfile.py When you try to call any jfree stuff it will crap out when run as a standalone jar file, or a web start application. The fix is that you NEED to include jcommon in the classpath (or jar class-path, or as a href in a webstart JNLP file). You might even be able to include in the -A flag.. (haven't tried that yet). I think this will probably hold for many external java libraries that require other dependent jars when deploying byte code compiled jython, even if the external jar is compiled with the other one.. e.g. (jfree is supposedly compiled with jcommon in it). I am not sure why jython can't load it, before, I would get some static constructor initializer exceptions.. which lead me to believe that the referenced classes couldn't be found or are not loaded properly.. (might not be a jython issue). Hope this helps, Simon Hey all, Jython run fine on android ? If not, are there a effort to do that works ? Thanks, Beyonlo Modules don't inherit the namespace of those that import them. If you name the interpreter locals namespace, say '__main__', then your module could do this from __main__ import DrawMediator To name the namespace, create your interpreter like this: _interp = new PythonInterpreter(); PyModule mod = imp.addModule("__main__"); _interp.setLocals(mod.__dict__); _interp.set("DrawMediator", drawMediator); _interp.exec("import header"); Wouter Deketelaere wrote: > Hi, > > why can't I access an Java Object during the import of a module. > > In Java, I have: > > DrawMediator drawMediator = new DrawMediator(); > PythonInterpreter interp = new PythonInterpreter(); > interp.set("DrawMediator", drawMediator); > > I have a module called header.py which has to be imported, but I can't > reference the DrawMediator object during that import process.

Matplotlib: custom projection for hemisphere / wedge I am looking at custom projection in matplotlib gallery - I am trying to change it should only plot the southern hemisphere. I adjusted the required [-pi / 2, pi / 2] limits to [-pi / 2.0]. Now I am looking at: def _gen_axes_patch(self): """ Override this method to define the shape that is used for the background of the plot. It should be a subclass of Patch. In this case, it is a Circle (that may be warped by the axes transform into an ellipse). Any data and gridlines will be clipped to this shape. """ #return Circle((0.5, 0.5), 0.5) return Wedge((0.5,0.5), 0.5, 180, 360) def _gen_axes_spines(self): return {'custom_hammer':mspines.Spine.circular_spine(self, (0.5, 0.5), 0.25)} As you can see, I replaced the Circle patch with a wedge. This is what the projection plot looks like now: The spine still follows the circle / ellipse - how can I indicate that I want the spine to follow the wedge border? I'm not sure what is the best way to change the spine, so any help would be much appreciated! Thank, Alex source to share Just for the record, you are sure to jump straight to the deep end of the pool if you are still new to python. (And you, luckily, right now!) What you are doing requires a fairly detailed knowledge of the inner workings of matplotlib, which is a fairly complex library. That being said, this is a good way to learn quickly! For something like this, you need to understand the internal architecture of how things are structured, not just "public" apis. For most of this, you need to dig in and "source". For any project, the internal processing documentation is the code itself. That was said, for a simple case, it's pretty straight forward. import numpy as np from matplotlib.projections.geo import HammerAxes import matplotlib.projections as mprojections from matplotlib.axes import Axes from matplotlib.patches import Wedge import matplotlib.spines as mspines class LowerHammerAxes(HammerAxes): name = 'lower_hammer' def cla(self): HammerAxes.cla(self) Axes.set_xlim(self, -np.pi, np.pi) Axes.set_ylim(self, -np.pi / 2.0, 0) def _gen_axes_patch(self): return Wedge((0.5, 0.5), 0.5, 180, 360) def _gen_axes_spines(self): path = Wedge((0, 0), 1.0, 180, 360).get_path() spine = mspines.Spine(self, 'circle', path) spine.set_patch_circle((0.5, 0.5), 0.5) return {'wedge':spine} mprojections.register_projection(LowerHammerAxes) if __name__ == '__main__': import matplotlib.pyplot as plt fig = plt.figure() ax = fig.add_subplot(111, projection='lower_hammer') ax.grid(True) plt.show() Dig in the method a bit _get_axes_spines : def _gen_axes_spines(self): """Return the spines for the axes.""" # Make the path for the spines # We need the path, rather than the patch, thus the "get_path()" # The path is expected to be centered at 0,0, with radius of 1 # It will be transformed by `Spine` when we initialize it path = Wedge((0, 0), 1.0, 180, 360).get_path() # We can fake a "wedge" spine without subclassing `Spine` by initializing # it as a circular spine with the wedge path. spine = mspines.Spine(self, 'circle', path) # This sets some attributes of the patch object. In this particular # case, what it sets happens to be approriate for our "wedge spine" spine.set_patch_circle((0.5, 0.5), 0.5) # Spines in matplotlib are handled in a dict (normally, you'd have top, # left, right, and bottom, instead of just wedge). The name is arbitrary return {'wedge':spine} Now there are several problems with this: - Things are not centered within the axis correctly - The axes patch can be scaled a little more to properly tackle the room within the axes. - We draw the grid lines for the full globe and then crop them. It would be more efficient to just draw them inside our "bottom" wedge. However, when we look at the structure HammerAxes , you will notice that many things (especially centering the axis patch) are effectively hard-coded in the transforms. (As they note in the comments, this means a "toy" example, and, assuming you're always dealing with a full globe, makes the math in transformations much easier.) If you want to fix this, you will need to configure several different transforms in HammerAxes._set_lim_and_transforms . However, it works well enough as it is, so I'll leave this as an exercise for the reader. :) (Be careful, this part is a little more complicated, as it requires detailed knowledge of matplotlib transforms.) source to share	https://daily-blog.netlify.app/questions/1891945/index.html	CC-MAIN-2021-21	refinedweb	756	66.54

Standard C Library (libc, -lc) #include <unistd.h> int usleep(useconds_t microseconds); The usleep() function suspends execution of the calling thread until either microseconds microseconds have elapsed or a signal is delivered to the thread and its action is to invoke a signal-catching function or to terminate the thread or process. The actual time slept may be longer, due to system latencies and possible limitations in the timer resolution of the hardware. This function is implemented using nanosleep(2) by pausing for microseconds microseconds or until a signal occurs. Consequently, in this implementation, sleeping has no effect on the state of process timers, and there is no special handling for SIGALRM. The usleep() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error. The usleep() function will fail if: [EINTR] A signal was delivered to the process and its action was to invoke a signal-catching function. nanosleep(2), sleep(3) The usleep() function appeared in 4.3BSD.

the annoying thing about JavaFX is that many basic operations have to be done by yourself. By default, entering carriage return in TextArea will lead to line feed, but in many scenarios, we want it to trigger the sending of information instead of line feed when the user enters carriage return. Line feed is triggered by the combination of Ctrl+Enter. In JavaFX, there is no simple and direct method for this function, which is not the case in all UI languages, but JavaFX does not provide a direct API. After stepping on the pit, the author finally realized this function in JavaFX. The implemented algorithm is roughly as follows: Use the processor onKeyPressed of TextArea to listen for keyboard input events of TextArea. If the user inputs a carriage return, make the following judgment: If the user does not enter the key combination CTRL+ENTER, remove the line break just entered, and then send the text. At this time, you can choose whether to empty the contents of the text box or keep the contents of the text box unchanged. Then the algorithm ends. If the user enters the key combination CTRL+ENTER, insert a line break at the cursor, and then move the cursor after the line break. Then the algorithm ends. If the user does not enter enter and does nothing, the algorithm ends. The main precautions are as follows: The range of the text box cursor is [0, length]. Because the cursor points to the gap in the text, and the number of gaps is 1 more than the text. The callback method of the processor onKeyPressed is triggered immediately after the user presses the key (before it is released). TextArea does not consider the combined keys entered as the sum of the effects of these keys in turn. This means that when you Enter after pressing but not releasing the Ctrl key, the text you Enter will not contain line breaks, because TextArea does not think you are entering Enter at this time. However, if you press (do not release) a and Enter in turn, the text entered is a\n. In the callback method of onKeyPressed, when the user enters an ordinary key, the cursor position is the position before the character is entered (the character just entered has not yet taken effect in the text box). If the user enters a special key (such as Ctrl, Alt, Enter, etc.), the position of the cursor is the position of the cursor after the key takes effect. In addition,. This means that if you Enter enter, when the onKeyPressed callback method is triggered, the text box contains not only a newline character, but also the cursor after the newline character. When splicing the text on both sides of the cursor, the cursor position and text content of Enter and CTRL+ENTER are different. For Enter, you need to clear the line break, and the entered line break is to the left of the cursor. For the key combination CTRL+ENTER, not only insert a line break, but also move the cursor to the right. Windows interprets carriage return as \ n\r, but TextArea clears all \ r in the text.

Linux Mint 7, based on Ubuntu 9.04 “Jaunty Jackalope”, and planned to be released in May 2009, will be codenamed “Gloria”. Question to Linux Mint users: In Mint 6, mintMenu was labeled “Menu” instead of getting the traditional release codename (“Felicia”). Do you think it should remain “Menu” in future releases or would you prefer us to use the codenames again? Edit: Thanks for all your comments. It looks like the right thing to do is to name the menu “Menu” but to also have a tooltip on it showing not only the codename but also the version and edition of Linux Mint. Since the text is easily configurable I don’t want to add that choice to mintAssistant. I released an upgrade in Romeo for mintMenu to show that information in the tooltip. Well, if I remember correctly, “Menu” was adopted to make mintMenu more appealing to other distributions. I still think that’s a good idea, but if the change is easy, I’d rather see the codename in Mint. Especially “Gloria” – awesome word to decorate the menu (glorious). I think the menu should be just an icon, with no text. _ I think you should leave it at menu, people would know what distro they install on their own computer. And if it means just a little bit less coding you guys have to do, then all the better. Mik “Menu” or “start” or anything along those lines sounds better when referring to it with someone else. I agree with Bubba, I prefer the codename in the Mint release. I second that — Mint sounds good. Also, please please please, post full content to RSS feeds. Non full content are EVIL. And you’re not EVIL, are you? 🙂 I’d go with “Menu”. It ‘remove’ the confusion between the differents codenames on the new users (or newbies, or average user). Fantastic Felicia was an awesome release. Really looking forward to Great Gloria 😉 . As for mintMenu, what if mintmenu defaulted to “Menu”, but then “mintdesktop” switched it to the distribution name on install? Either one works for me. To be honest, I’ve been removing the menu text in there and just having the Linux Mint graphic to save taskbar space. KDE does the same, they don’t have any text beside the menu graphic…. please change the network manager with the quick resolving speed I think “Menu” is much better. It provides a level of consistency, professionalism, and ease of use. When, for example, I need to walk my father (an extreme newbie) through a process over the phone, it’s a lot easier to train him that that is the “Menu” button to get to his menu, rather than having it change names on him every time we upgrade his OS. “Menu” explains what the button does so newbies don’t have to guess “What does the Felicia button do?” If the goal is winning over Windows users and newbies, “Menu” is much friendlier to help get them going. I realize that for us, the computer literate, this may seem trivial and takes all of 5 seconds to change, but newbies may not always have someone available to help them with these things. So I think defaulting to the simplest option is best, and those of us who prefer the codename instead will know how to change it. Thank you so much for all your hard work! All the best. I don’t care. John Make it the codename. Menu is too generic. We like unique Stay with menu, it adds simplicity and removes confusion def stay with menu. makes it easier to know what it is. i think menu will be much better.. since we are mostly targetting the first time users.. it avoids a lot of confusion Gloria is a great name for Mint7!! for MintMenu, I prefer the Distro Code Name, but I understand the arguments to keep Menu as name. My Idea is to add an 3-point-Option in mintAssistant to make the Choice of the name: -Distro-Code-Name -or place free to type a own Name Why mintAssistant? because it run directly on the first boot of LinuxMint (and it can be consider as new feature in Mint 7) Please just leave it menu. Just keep it simple. I liked “Menu” as the text better than the codename; I think it looked more professional as well as more appealing to new and potential users. But I also think “Mint”, “LinuxMint”, or just plain “MintMenu” would look nice too. I really like the idea of giving choices for the menu text in mintAssistant! For me prefer the word “Menu” coz it makes it look more like the menu.. Its more simple and straight forward rather than the codename itself.. The codename could be placed somewhere else.. I dont think it should be shown in the taskbar itself.. Definitely leave it as “menu”. I’d vote for “menu” too, using codename may be a bit confusing. Definitely change back to code names. Yep, codenames have been confusing my friends, since most of them are windoze users. Stay with the Menu label. I agree with Herman in comment 2 that it looks best with just the icon. However, from a usability standpoint, especially for newbies, I think “Menu” is best. It makes it obvious what the mintMenu is from the start, whereas when I first started using Linux Mint with Elyssa, I was a bit confused at first about what the button was all about. Great work with Linux Mint, definitely the best out-of-the-box distribution I’ve seen thus far! Menu. But if a more complex solution is alright, I prefer having a mintAssistant option for it. Prefer codename. The first thing I changed in Felicia was renaming the menu to Felicia. Other distros can change it easily, and the codename is a part of the identity of the release. Vote: “Menu” I think just an icon would be the best!. “Mint” sounds good. Menu. “Start” would also work. I liked what Logan said: MintMenu might be interesting… Otherwise just “Mint” works too… And keep up the awesome work! We’re all really excited and we love Mint much! (I even got a shirt with it to “spread the love”. Thanks Clem for the Name. 🙂 I had the same idea as knuckles.with the mintAssistant its nice to change it and with a mouse hoover that describe the menu like “MintMenu to start Aplications…” or so ? like the other progis in the panel. i prefer the Distro name. 😉 I prefer MintMenu. I think we should stick with Menu. A couple friends I have converted to Linux were confused with the names on the menu. Menu or Mint or MintMenu is fine. We can, after all, change it ourselves by right clicking the icon and choosing preferences then the main button tab…!! Can’t we..?? 😉 And I am sure you CLI giants can change it from the terminal too. I for one don’t want a females name on the menu button (Don’t mean to sound sexist or anything) but having Gloria on the menu button aint gonna impress anyone I know who wants to make the switch to GNU/Linux. Why try to ruin a very good Distro with a stupid code name on the button. just start a poll about that… Personally, I prefer the codename. Just “menu” looks equal to any graphic interface or any operating system. The codename would be more peronal. Hey folks! I would also stick with the simple Menu label. Your codename could certainly be shown somewhere else in boot screen, boot sequence or default wallpapers. I’m sure everyone would get the message its Gloria. Menu is more conventional and user friendly, less confusing as some have already mentioned. Although, permitting to choose either one or the other would also be fine. “Menu” makes more sense. I never saw the point in calling the menu by the distro code name… It doesn’t belong there. Stay with “Menu”, this is definitely the mature choice… Release name is too geeky for the general public, it doesn’t mean anything for non-geeks… “Menu” is the only way to go… It really says what it is… An icon (without any text) would have been nice, but it is still not as straight-forward as “Menu”… I like having the name on the button … reminds me of what the heck I’m using LOL No seriously … I’m for real. I like the name. It is very EASY to change it to your own preferends…but I like the codename. So, in Mint 6 I changed it promptly from menu to Felicia. I always rename it to “Linux”. 🙂 Menu is fine….but I like the option that is available by right clicking ‘menu’ and choosing ‘preferences and changing the name so instead of ‘Elyssa’ it brings up the name “Glynnux” instead of menu which makes me look dead posh. 🙂 So menu as default with the option still available…very sorted! ..a nice option. I myself always switch mine to having only an icon & no text, however I feel that for new users ‘Menu” would be the best as it does save them from confusion. I have had a few friends say “Who is Elyssia?”, & “why is this woman’s name on my Operating system/Computer?” So then I told them, & they said “well I don’t like it, is there anyway I can change it? Because if I cannot I do not want this on my computer.” Then I told them how to change it & they was happy & they changed it to just the icon or to their own name. So when Falcia changed it to ‘Menu” I was very happy & none of my friends complained about that one. So yes keep it as ‘Menu’ it apparently is a deal breaker for some new users. Also I wanted to mention that Gloria is my mother’s name 🙂 She is going to be very excited about having a Linux distro’s version codename being the same as hers, though she prefers KDE desktops :p . I have changed “menu” with “Felicia” immediately! I’d second the proposal to let the user decide in mintAssistant. Put the release name. Differentiates(sic) you from the rest. Awsum distro by the way! oh, “menu” is such a neutral, boring word. “felicia” just makes me feel cooler. …or to put it in minty words, more elegant. I run a multiboot system, including Elyssia and Felicia distros and sometimes also Linux Mint community editions as well. labelling the menu button explicitly helps in distinguishing which Linux Mint I’m running, and “humanises” Linux Mint as well. The placement of the menu button at the bottom left of the display should implicitly attract uninformed users to just select it at the beginning. I am new Linux convert and Linux Mint 6 adopter (as in yesterday) which is basis for my opinion: I prefer leaving it as “Menu” with the icon next to it by default. It really makes it easier and less confusing for new people to navigate around. If it’s also easy for the user to relabel to their own tastes, all the more better. I use 6 computers with Mint. Some have Nvidia GForce2Ti garphic cards and 3D runs smoothly with Mint 5 but i’m unable to get 3D working with Mint 6. So some computers run Elyssa and others Felicia. It’s very usefull to know wich version is installed on each computer. If you decide to keep the Menu button you should let an icon with the code name. Thanks for the job. I like the idea of giving the user a choice in mintAssistant. But might I also suggest labeling it ‘Mint’ as another alternative. Thats what I changed mine to. It fits the Distro not just the release. And I don’t think new users would be overly confused. After all, most people who have used a computer are familiar with having an icon in the bottom-left where they Start all their programs. So I don’t think its NECESSARY to label it Menu, but you could go ahead and offer anyways. P.S. I just started using LinuxMint the other day, and I love it. I will be recommending it to new users interested in checking out linux. Thanks guys. How about set it to the computer’s network name, or give some options during install on what to name it. I prefer version’s codename. Add the option to choose in mintAssistant then it would be perfect for everyone Far more professional if it’s called menu. Keep it simple – press the menu button and guess what – up pops the menu. “Menu” works just fine… I would like to have the option to decide through mintassistant (great idea). After installing Felicia, I removed the word “Menu” and left only the icon. I vote to either include the option in mintAssistant or leave it as “Menu”, which looks professional and will not risk discouraging new users. Menu is too plain. I like the idea of Gloria or just the LM icon. I teach two Linux courses at the local community college. I have my students download and install Mint onto their hard drives primary for the simplicity for winblows… excuse me, windows users. They have never asked me where the “start button” was. I don’t like the idea of calling it “Start” as adam and aircave suggested. It reminds me too much of MS. Ninety percent of the OS’s, Linux, Apple and MS have the “menu”, for lack of a better word, in the same place. People will understand what it is. I like the codename as “Startbutton”. But as someone before said, maybe it’s too geeky for general public. So personally, I would make a users-choice during install (with two previews of each startbutton or taskbar). “Menu” is much better and stand for the MENU is The codename as the menu text was much better imo. I feel it gave the distro some character. “Menu” is just too horribly bland and generic for my tastes. I vote for “Mint”. That’s what I always change mine to. Linux Mint, That is great that Jaunty is coming up. Just one note if I may. Older monitors are not being recognized with the new tool being used to recognize the monitors. Fairly modern one’s have no problem. I have kept to Elyssa version and Hardy Heron because of that fact for uniformity for all our computers at home and at work. I’d have the older Hardy Heron display tool available or make sure the tool is better designed. I would like to see the code name come back. The first time I loaded Mint I knew it was different in the first moments of use. Not Menu,or start but Daryna. And I have stuck with it ever since. It is for me the right distro and I like the different approach. Thanks for asking Mike I miss the codename of the edition. Put Gloria there! Menu is for restaurants. Call it Gloria and keep the option to change to Menu for those who so wish. I love it ! Thanks. MINT in BOLD letters, or just a slightly larger Linux Mint logo should suffice. Like “noharddrive” said, you only have to right click on the icon, go to preferences then the main button, and choose the name or words we want, or to have an icon or not. codename plz Just an icon would be enough. Maybe the icon for menu should be redesigned to make it stand out. Menu – definitely. Why? Because that’s what it is… it’s a “MENU”. It isn’t a “GLORIA”. Always label GUI items with dead-on accuracy. The menu button will probably be the very first interaction new users will have with Mint – so it’s not a good place to be cute. Those who prefer something different can change it in 2 seconds. Branding can go on the wallpaper. GUI labels should always be as clear as it is possible to make them. Doesn’t really matter to me as I can always change it. But I would like to see the Mint version and 32 or 64 bit somewhere on the menu. Menu should remain as the default as Lisa points. For newbies is easier to understand what it does…. I prefer to have the release name but I can always change it. I guess all the others which prefer the name can do it themselves, contrary to the newbies which may not find that intuitive to change the name of the button. I would leave it as menu, which perfectly describes what it is. Stick with menu My girlfriend once asked me who Elyssa was and why her name was on my computer. Since it’s easy for the more advanced users to change it to what they prefer why not keep it simple for the “newbies”. Ans besides, less to explain to the girlfriend. 😉 Doesn’t really matter. Only takes a second to change anyway. I like “Menu” The title is the function, very straightforward. Menu or an Icon. Menu or an Icon. Better yet maybe we can make it customisable. Mint Menu; Mintu? It is a matter of taste; my personal hierarchy of solutions to this issue is as follows (with most preferred method at the top): MENU — makes it easier for noobs MINT — keeping it real with the branding (icon) — understated and classy MINTU — to coin a phrase which would merely evoke more chaos. I have used Mint since Bea. I always change the Menu Button text, so I don’t personally care. “MENU” in all caps would be the user friendly and professional choice. The first thing my father asked me once I installed on his PC was how to get rid of the woman’s name on the Menu button. Comment #10 above said it best, giving very valid reasons for her vote. Though I’m convinced the option to choose during installation is best, if that won’t be available I vote for “Menu.” Using the codename as the label may be a nice sentimental touch for some of us, but serves little purpose beyond that. A menu labeled as “Menu” is professional and practical. Thanks for a truly great Linux Distro. “Menu” should be the default. It’s easy to change it if need be to suit one’s own taste. Actually, “Mint” means “Lie” in Romanian – as in telling lies. I don’t know if “Menu” means anything bad in some language but it’s a generic name, it really means what it says and having one word throughout the versions is a good thing considering some of us also offer technical support and it’s easier to say: “Click the Menu button” rather than “Click the bottom-left button named Bianca or Daryna or Elyssa or Gloria”. 😛 “Start” is not a good name. It’s strage to click start to stop your PC, ain’t it? If we’re talking about a graphical button without text we should consider something that can easily be described in a word or two, not more, also for technical support reasons. How would you describe Mint’s logo except for “the cute green thing”? Linut Mint has green stuff almost everywhere so it can get a little confusing. So far I would go for the “Menu” version. I originally argued in the forums for “Menu”; also being impartial with having “Mint” or “Gloria”. BUT People above have mentioned that its easy for newbies to understand “Menu”, some say its more professional. I respectfully disagree posed by comparing the following two situations. Situation 1: Command from Administrator: Click on Menu Interpretations from newbie: Click on the LM Menu / The menu which I recently told you to click on (ie File Menu) / Taskbar (could be misinterpreted on exact differences on where Menu ends… the menu) Situation 2: Command from Administrator: Click on Gloria / Start ™ / LM leaf icon Interpretations from newbie: Only the Actual menu which we are refering to. Not Rightclick menu, or file menu, or a list of files on your computer misinterpreted as a menu. If you don’t get where I’m getting to, google “Disambiguation” I would like to see “Mint Menu” as the default. Cheers! i’d say, u make a poll Clem..and i’ll vote for the codename.. It should be nice if you have the word ‘Menu’ and when you move the mouse over it change to “codename” or maybe ‘Mint’. I prefer “Mint”, and showing only the icon it’s a good idea. Also, my girlfriend gets gealous if she sees a woman’s name at compute xD i think only icon is best option..there is one theme in gnome-look naming glass..is best made menu button i m using that on my current mint..check out pls I think you should leave it at menu, people would know what distro they install on their own computer ‘Menu’ might be better for newbies, but the release name is more original and unique. I think that might be a possible option to choose from mintAssistant. I would prefer the code name, as its the only place thats always visible & highlights what you are running. Also it gives vlaue to the code name (As long as the code name is short). I agree with “diego1188”, it may be a good iidea to put the option in the assistant, and the user choose his favorite. In the oher side, Iĺl prefer only the buton o “Mint” in artwork I like the codename, though I can see the arguments for menu and it is probably a better choice for newbies .I really like the idea of being given the choice in mintassistant MintMenu is the clearest and best for every new Mint distro, i thing. By the way, you made well by fixing the “Filter” in MintMenu My vote: Use “Menu” as the default, but offer the codename as an option to switch to. (It’s already been suggested, but I thought I’d add my agreement….) I understand both sides of this, but I agree that menu/programs/start will be more familiar to new users, I like the idea of having a choice in mint assistant, but I would really like to see the button redisigned with changable text intigrated into the button rather than next to the button. I prefer the codename (dare to be different, and it also helps me remember which version of Mint I’m running on each machine), but a choice would be good. In Bianca it was fairly easy to rename it to anything you wanted, which was nice. I also liked the start-up screen in Bianca better than any other version. I like a little individuality between releases. Even if it is something as small as a little label. JMO I rather like the codename but I can also see why many would prefer it to be descriptive of what the button is for. The only extra reason I can think of for using the codename is that it makes it easy to find out which version the newbie at the other end of the phone line is using. I prefer the version name instead of menu I like the idea of asking the user to choose in mintAssistant. distro name custom name otherwise, I think the idea of making “Menu” the default label is good for newbies, but it should be more unique to Mint, “like MintMenu” or “MintStart”. I’ve always changed the default name on the MintMenu to just the icon with no text. I’d prefer it that way, but honestly, whatever gets done, the tweak is an easy one for me! Menu makes it easy for everyone. And if your preference is for the code name then it is easy enough to change. Thanks for your excellent work guys, you efforts and Mint made me a Linux convert forever! Damian Make it the “Clem” button, hardwired in forevermore! We can tell everyone to “just click Clem” and that it stands for “Complete Linux Entry Menu”. And maybe it could sport a leprechaun on the button?! But, more seriously, I agree “Menu” would be better for a default. Just an icon (like KDE) would be nice to have, but users should still have the option to add a name. i think the name should be left at menu, however i have two suggestions, 1) in the settings the user can choose what to display, either “menu” or “gloria” and 2) if you wish to maintain only the “menu” you could add a wallpaper with “gloria” written on it I would say use “Menu” as it’s a good default. Please do not use “Start”. vote: a simple and nice icon instead of menu if I have to choose from text, I’s prefer codename Hi, yh stick with menu imo, makes it easier for everyone 🙂 also totally random and off the topic, but could you bundle JRE v.1.6 with version 7, as i cant seem to get it installed 🙂 I like the Clem button idea. A nice graphic that spelled CLEM would work too. Fire up Gimp and lets come up with one!!!! Someday Linus and Clem will share the same OS!!!! Maybe change the acronym to “Customizable Linux Entry Menu”… 🙂 definitely keep the “menu”. It is the first thing I always did when firing up Mint and I have used it since its first week’s launch. It is more accessible to those who haven’t used Linux and I don’t always like to look at the names all of the time. I was thrilled to see the change. Thank you, Keith I like “Menu” better than distroname. Cooler still, would be if I could figure out how to change it to username – whichever one of us is logged in at the moment. Leave it Menu. Put a nice graphic of the name at the top of the menu when it opens. The reasons I switched to Mint were that my wireless card just worked, and the little touches like Elyssa (my favorite name so far) as the menu name. It adds to that minty personality everyone seems to love. i vote for Mint logo+Menu – standard I say keep it as menu, this distro is geared towards noobs. But also if someone wants to change it, or even take it off and put an icon, that option should be available too. all is good!我喜欢linux mint！！！希望能有更好的中文支持！i hope a better support for chinese! Cyanide: Sun’s JRE 1.6 comes pre-installed in both Mint 5 and Mint 6. Thank you for your releases. My wife believes that Daryna and Elyssa are my secret girlfriends. So I prefer ‘Menu’. Regards. I prefer the code name instead of Menu, its kind of a reminder of which Mint I’m using. I think that it should say what version…By Name….Elyssa Daryna and such. 2 reasons. 1. Helps people identify what version they ahve easy. For easier help. 2. Unique…..Just cause winblows uses 1 word on all….That to me is enough to keep changing it…… If you keep using Menu M$ will try to get you saying you took their idea, lol(Joke). But on the Real. I think that it should have the Name of the version in Use….If they don’t like it they can always change it with a simple right click…. I suggest miñtu. The tilde over the n makes for a pronounceable combination of the word mint and menu. MoonForce: Thanks, I’ll make sure to give it a try. I prefer Menu, it is easier for newbies 😉 Keep it as Menu An elegant OS like Mint, should have the name of the lovely lady on the menu. I changed mine from menu to “Felicia” that is a pretty name. use “mintMenu of (codename)” for distinguishment. And let users set between in mintAssistant, and MintMenu Options. Thanks. GiggleGut: It is customizable you very, very silly boy make the Menu customizable – give option to allow or deny movement. And plz program a MintMenu for XFCE and K Desktop Environment! Linux Mint 7, ditunggu diIndonesia salam dari Indonesia I think it is time to make the 64bit edition of Linux Mint 7 “Gloria” as main edition and 32 edition separately as an option to old computers. It is almost impossible to buy 32 bit computer nowadays and 64 bit software, as we can see, gets to be usable already. I renamed my menu button Billgates in honor of the man who inspired Linux development. Without Billgates, we’d all be using OS/2 or some other operating system that never crashes, and Linux would be residing on the abandoned old hard disk of some unknown Finnish grad student. 🙂 As long as it can be changed to whatever I dont mind. But I think its a nice little Mint tardition to have the Codename there. In 6 I changed it to Felicia too. As for my parents I changed it into “start” I prefer the Menu/Start label. Another text could lead to confusion for new users/switchers. I agree with [i]Daniel aka knuckles[/i]. The perfect solution would be to allow individual users to choose. That being said, if it [i]had[/i] to be one way or the other, I would opt for “menu” Menu is fine for the… Menu 🙂 Otherwise my girlfriend gets jealous… 😛 menu or start is the past and the obvious, putting gloria here it’s more fresh like mint style.. or a cool icon or the user decid what the heck says: the user decide with an option like knuckles+Steve says. I just started with Mint 6 “Felicia,” and wasn’t aware that the old menus used to have the code names. I actually prefer having the term “Menu” listed. One thing I noticed is that I’m given a choice to either keep or hide the LM icon next to “Menu”. Great option, so would it be feasible to offer the user a choice between “Menu” and the code name? Hi, Just adopted Mint a week ago, after going through >Ubuntu 8.04 and 8.10 and accidentally stumbling upon Mint when googling “fastest Linux”. Lucky for me. Best distro I’ve come across for ease of install and ease of use, even compared to Ubuntu. GUI is beautiful and elegance is an appropriate description. Don’t even want to change the default desktop settings cause they are so nice. As a Linux newbie I think Menu is a better choice as anything that makes the conversion from W***s easier is a good thing and your menu layout in Gnome (haven’t tried the XFCE layout cause it wants to uninstall the Gnome desktop) is simplicity and clarity exemplified. Took me all of 15 minutes to figure out how to configure just about everything I needed to on the system. I see that the Preferences option gives users the ability to customize the text as well as choose between the icon and text or both. I think leaving the default “Menu” and letting users change it if they want is the best option for Linux newbies and W***s converts. On a different note, will it be possible in the future to install both the Mint-Gnome desktop and the Mint-XFCE desktop and choose between them at log-in the way Ubuntu lets you? Thanks, Chris “Mint” sounds good ! I think it’s intuitive enough with the placing of the button, everybody understands that it’s a menu just by the placement. Thus the text “menu” is redundant. If any text should be besides the menu I think it should be the codename. Codename or nothing I say (preferably nothing). Looking forward to Gloria! Leave it with menu…….. or a larger LM symbol with no text man your distro is top notch and the best availiable man. I personally reccommend it to all and sundry. Please everyone use mint now. I said now dammit. NOW !!!!! DEFINITELY USE MENU Just use menu, its more professional than a name, its supposed to be a user friendly distro so keep it simple for the end user by having the environment resemble what they are used to (Start). keep it menu! I like the idea of being able to pick your own option. Maybe have a default of ‘menu’, with the option of changing either on a custom options install or in a preferences location. But if that is way to much work, I would go with just an icon. very good! My opinion is the simpler the better. Perhaps some shadowing when clicked instead of highlighting in blue, or a simple animation. Pizazz is nice, but the main key to elegance is simplicity! Felicia is a nice release. =) Looking forward to the Gloria release. It’s also nice to change the name “Menu” to “Gloria” =). Just a suggestion: Should shrink the desktop icons a little bit maybe 32×32? “Go” or “Go to” I think the text should be “Start”. People who want something unique can change it. Strange names appeal to the geeks in us but does not make it easier for the general masses. Little things like these matter. If something is configurable anyway, it is better for the defaults to side with the common people. We geeks can always change it if we want. Also, pressing the Super button should start the mintMenu. codenames I hope any problems, with ATI drivers, are to be solved. I cant use compiz desktop cause of that… its a shame. Other than that, GREAT JOB YOU GUYS !!! (ATI X600 PRO 256MB) Why not have it be user choice? I really like the simplicity of “Menu”. Perhaps there could be some radiance in the OS? Brighter colours and sharper lines in the panes and panel. Perhaps a new theme to project the glory of Gloria? Hey, I just think that the people who make opensource software are so worried about such little things! The MintMenu, as it is, can be renamed as you wish. It is just one more option to make your own look to the system. I personally hate the visual of Mint, although I love this system, and I always change it radically. We should remember that we’re having a great advantage in having this option! Winblows users can’t modify much of the look of their boxes, and we can! Producing look patterns, in this sense of view, is a bullshit. LET’S NOT WASTE TIME WITH POOR AND SMALL THINGS! THINK BIG, PEOPLE!. I nice ICON would be nice and simple. Well it’s so easy to change… you can put whatever you want… right clic, settings and there we go… Well maybe «Mint Menu» by default is good… well me I changed it for “minto” lol… the name of my local domain… ^^ Personally, I think it would be pretty cool if you could get it to dynamically display the hostname of your machine … imagine that on a network … New user will surely be confused by the code name. Experienced users will surely know what version they have installed. So it must be “Menu” for sure. I can’t wait to see the 64 Bit version of Gloria, I’d like Mint more if you could just upgrade distributions from the Update option like in Ubuntu. Instead of having to install over my old system and have to re-do all of my changes I like to make. But overall Mint keeps getting better and better with each release. NOT keeping things simple (i.e. the names of Linux programs etc…) is keeping newbies from diving in and trying the O/S. It did for me, example, Windows Media Player and Kaffeine? Huh? Do I want to watch videos or make coffee? Im waiting!!.. i started with mint 5 and now i use mint 6 and i like it but my webcam doesnt work, and someone knows if this new release bring more suport for webcams? Why not have it so that it can be changed by the user? In Ubuntu you can easily do this. But imo the defaulot should be menu. It makes more sense, having the Lunux mint icon then the word menu… Mint>menu 🙂 Perhaps if there is so much undecided and argumentitive conversation over such a trivial thing there could be simply a choice when setting up the OS by the user to their liking? Cabras en vinagreta rules! Linux Mint rules! I have already Windows XP installed on my system (Drive C) While installing Linux Mint 7 I selected USB drive. Now when I start my machine it presents a menu for selection of windows XP or Linux Mint. It works for both. But if I plug-off my USB, machine fails to start in xp or Linux Mint. Can any one tell me how to uninstall it from USB as I want to reinstall Linux Mint on my Hard Drive, keeping my windows XP intact. Hello. I want to ask you something. When I try to install Mint 7 on a partition from live usb, I get an error that says something is wrong with root. Also I tried to install Mint from Windows, it requires internet connection but says “Retrying connection”. Can someone help me?? Can I install the image of Linux without a CD? I prefer the codename. Its cool to have that. I’d love to see a wubi installer for Gloria 🙂	https://blog.linuxmint.com/?p=543	CC-MAIN-2022-33	refinedweb	6,332	82.14

There's a levelplot method too, which is currently experimental. These are Trellis analogs of existing coda functions, and may in future replace them. 0.9-5 - Fixed bug in summary.mcmc (safespec0 misspelled) which affected univariate chains. 0.9-4 - Fixed documentation errors. 0.9-3 - Added date stamp check in read.openbugs to ensure files were created at the same time. 0.9-2 - [RGA] Added an autoburnin flag (default) true to gelman.diag to suppress automatic windowing for burn in (so I can do it manually). - [RGA] Fixed a problem where summary.mcmc.list would not give correct pooled standard errors. - [RGA] Fixed propagation of standard par and titles to plot.mcmc and plot.mcmc.list. Also fixed so that ask will default to value in par(). - [RGA] Fixed a problem where autocorr would apply thinning twice to mcmc.list objects. - [RGA] Changed effectiveSize for mcmc.list to sum across all chains. Original behavior can be recovered by using lapply(x,effectiveSize) - [RGA] Added autocorr.diag function. - [RGA] Patched summary.mcmc and summary.mcmc.list so it would give standard error of NA when spectrum0 blows ups. - [RGA] Added a rejectionRate method. - [RGA] Added a batch Standard Error Function 0.9-1 - spectrum0 function now has default max.length argument of 200. This means that the output will be batched to a length between 100 and 200 before fitting the glm to the spectrogram. This should improve robustness for chains with high autocorrelation, or markedly non-gaussian distributions. - The read.bugs() function has been removed; read.coda() has been modified to allow specification of both output and index files; read.bugs.interactive() has been modified in the same way; read.openbugs() is a new wrapper function around read.coda() for OpenBUGS output. 0.8-3 - Fixed documentation errors in coda.menu.Rd and linepost.Rd 0.8-2 - Added generic function thin to list of exported functions 0.8-1 Continuing problems with namespace: - Addition of namespace requires new version number for coda, as saved workspaces are not backwards compatible. - Ensured that mcmc attributes are not assumed for objects returned by as.matrix.mcmc, as this now no longer returns an mcmc object. This occurred in, for example, effectiveSize (which returned NA) and gelman.diag (which dropped variable names). - Changed "[.mcmc.list" and "[.mcmc" so that they return an mcmc.list/mcmc object respectively when subsetting columns. plot.mcmc() and plot.mcmc.list() now work again when there is only one variable. - Imported the required time series generics from package stats. Failure to do this may result in a saved workspace that cannot be reloaded. Other problems - Removed S compatibility (statements conditional on is.R and wrapper function coda.global.assign). Note that S compatibility never worked at all, and I now have no intention of supporting it. - Fixed (old) bug in "[.mcmc" which made column subsets of mcmc objects return invisibly. - Changed the plotting functions so it is no longer necessary to press return to see the first page of plots. 0.7-3 (changes done by Andrew Martin <admartin@wustl.edu>) - Added NAMESPACE - export only functions that I think should have been exported (based on the documentation and common sense). - Registered all S3 methods. - Fixed documentation for non-exported functions. - Patched the "mcmc" function to deal with really big thinning intervals. - Patched the "as.matrix.mcmc" function so it really returns matrices. - Fixed plot method, by having plot.mcmc pass an mcmc object rather than a matrix, and by fixing the [.mcmc.list method so it returns an mcmc.list not a matrix. - Fixed "varnames<-" which was broken when the as.matrix method was fixed. - Fixed documentation mcmc.convert.Rd such that the usage is consistent with S3 class definition (this fixed an error thrown in the QC tools). 0.7-2 - The spectrum0() function now returns zero when it is given a constant vector. summary.mcmc() (which calls spectrum0) now works correctly. 0.7 - Modified to run on R 1.9.0 with new organization of base library 0.6-2 - Fixed documentation bug in raftery.diag 0.6-1 - spectrum0.ar no longer crashes when the chain is a linear function of the iteration number - codamenu automatically drops variables that are linear functions of the iteration number - read.bugs renamed to read.coda. read.bugs exists as an alias. - initial support for JAGS: bugs2jags function converts WinBUGS data to R dump format used by JAGS. - added cumuplot function (not yet in codamenu system) 0.5-14 - Fixed reporting of sample size in densplot(), for variables that are in the range [0,1] or [0,Inf). Thanks to Roy Levy. 0.5-13 - mcmc() now works with data frames (provided that they contain only numeric values). 0.5-12 - Documentation errors in coda.options.Rd and nchain.Rd fixed. Thanks to Kurt Hornik. 0.5-11 - Fixed bug in mcmc() function that causes problems in Geweke diagnostic - Fixed geweke.plot so that it works with samples running from iteration N to 2N. These were previously mis-diagnosed as being too short. Thanks to Vasco Leemans for finding both bugs. - In autocorr.plot, the `ask' argument was not used.

Hi all, Me and my friend are trying to find a way to bake multiple texture with vray in blender, after some help we use this script: import bpy sce = bpy.context.scene Enable autosave sce.vray.exporter.auto_save_render = True sce.vray.SettingsOutput.img_dir = “//bake/” Enable Bake sce.vray.VRayBake.use = True Manual object list: ob = [‘cube’,‘plane’] for ob in objects: Selection for ob in bpy.context.selected_objects: sce.vray.VRayBake.bake_node = ob.name sce.vray.SettingsOutput.img_file = “bake_%s”%(ob.name) bpy.ops.vray.render() the problem is vray opens 2 windows to bake, but renders 2 times only the 1st object (cube). it’s possible to fix? thank you in advance!	https://blenderartists.org/t/vray-multi-bake-textures/567864	CC-MAIN-2021-49	refinedweb	114	60.51
Garbage Collection Test Hi, I am trying to test garbage collection. To start with i am using book O'Reilly - "Java Performance Tunning". In it i found the code below. But when I comment out //s=null and //v=null the time results are the same as with initialising them to null. Any ideas? Im I missing some aspects here? import java.util.; public class GarbageTest { public static void main(String[] args) { int SIZE = 40000; StringBuffer s; Vector v; for(int i = 0; i < SIZE; i++) { s = new StringBuffer(50); v = new Vector(30); s.append(i).append(i+1).append(i+2).append(i+3); } s = null; v = null; System.out.println("Sarting Garbage collection"); long time = System.currentTimeMillis(); System.gc(); long after = System.currentTimeMillis()-time; System.out.println("Garbage collection took " + after + " millis"); int[] arr = new int[SIZE10]; time = System.currentTimeMillis(); arr = null; System.out.println("Sarting Garbage collection"); System.gc(); after = System.currentTimeMillis()-time; System.out.println("Garbage collection took " + after + " millis"); } } Thank you But setting them to null shouldn't be garbage collected all those 2*40000 objects? no, of course not - how is an assignment statement that overwrites the previous pointer reference (s = new ...; v = new ...) going to leave the previous object still strongly referenced? :) that's what I would expect - the time difference with a pair of objects out of 2x40000 would be tiny ;) but obviously setting them to null is just for concrete correctness~	https://www.java.net/node/653837	CC-MAIN-2015-35	refinedweb	242	59.7
Asynchronous Functional Programming Using React Hooks In the first three parts of this series, we’ve looked at why functional programming is important to react, how to manage state in a stateless component, and how to replace the flux pattern or replace redux with React hooks. In this part, we’re going to look at how to handle asynchronous tasks in the functional programming world, and how you can use the async/await pattern when working with React Hooks and stateless components. I simply have to wait for something — being async in a synchronous functional world As you’ve noticed, everything that we’ve talked about until now has been completely linear and synchronous. If we’re just working with a simple webpage, that’s all well and good, but what if we need to use a backend, what if we need to venture into the asynchronous world? Luckily, useEffect is made for exactly that purpose. The React.useEffect hook takes a function as an argument and it will call that function after the main render cycle has completed, meaning that you can use it to complete async operations, like calls to an API remote, whether it be GraphQL or RESTful (or SOAP or really whatever you like). It’s generally best practice to define a function that you call from your effect and then do your async operations there. It allows you to use the async/await paradigm, which, I think we can all agree, makes life easier. Let’s take a look at a simple async handler, we’ll call it updateProductBackend. const updateProductBackend = async (product) => { return await updateBackend(product); } This is very simple, it doesn’t update our UI or anything like that, however, since closures are a thing that exist, we can use any variable in the current scope (including, say, a update function pointer from a useState call or the dispatch method from a useContext call where the context provider was initialized with useReducer to do that for us. Or, if we don’t want to use closures, then we can pass those items into this handler and use them there, they’ll still work. That might make this function look something like this: const updateProductBackend = async (product, dispatch) => { const result = await updateBackend(product); if (result.success) { dispatch({ type: “success” }); } else { dispatch({ type: “failure” }); } } Of course, for this to be meaningful, our middleware reducer has to be extended to handle the success and failure action types. The React.useEffect call Let’s now take the async handler we defined in the previous section and put it to use inside a useEffect call. In the body of any component, we can now add the following code: useEffect(() => updateProductBackend(product, dispatch)); Let’s look at our ProductDisplay component from earlier, and see how this fits in. const ProductDisplay = () => { const { state: product, dispatch } = React.useContext(ProductsContext); useEffect(() => updateProductBackend(product, dispatch)); return <Product data={product} />; }; This is fine, but the eagle eyed reader will notice that this effect will call our backend every single time that our state changes. We probably don’t want that. Let’s say that we’ve got a woot like item that increments our price by a penny each time someone buys. To do this, we’ll need a buy button, and then we’ll need to handle that price increment, but only if the product is bought. Let’s accomplish this with a state that tells us if the user intends to purchase (we’ll call it purchaseIntent), and then an effect to do the purchase and to increment the price. const ProductDisplay = () => { const { state: product, dispatch } = React.useContext(ProductsContext); const [purchaseIntent, setPurchaseIntent] = useState(false); useEffect(() => { const newProduct = { …product, price: product.price + 0.01 }; if (purchaseIntent) { updateProductBackend(newProduct, dispatch); purchaseProduct(product, dispatch); } return null; }, [ purchaseIntent ] ); return ( <React.Fragmemt> <Product data={product} /> <button onClick={() => setPurchaseIntent(true);} /> ); }; What you should note here is the fact that I’ve passed purchaseIntent as the second argument to useEffect. What this does is to tell useEffect that it needs to execute the first argument if the value it receives in the second argument is different from the last value received. Given that before the first time, it’s undefined, it will run the first time as well (hence the check on purchaseIntent). It’s also important here to note that if your call to useEffect has any long-running consequences, you need to return a callback that will terminate these processes. Wrapping it all up As you can see through these examples, hooks allow us to do absolutely everything that we would in the classic react lifecycle method, but everything is in a single flow, where we don’t have to worry about all the complexities that the object model exposed us to. This allows each piece to become a more discrete unit (which, as such, can be unit tested), and to keep all of the pieces simple as well. It also has the wonderful side effect of being faster. Since with this approach, your functions are not long-running and don’t contribute to the heap size like objects do, your app will have a lower overall memory footprint and run more smoothly everywhere it runs. Read More — Other parts in this series If you haven’t seen it, please also read part 1, discussing the reasons for functional programming and stateless components in react, part 2 managing local state with React Hooks, and part 3 replacing your redux action/reducer pattern with the react Hooks useContext and useReducer hooks.

Inner Class in Java Reading time: 20 minutes \| Coding time: 5 minutes In Java, an inner class is a type of nested class. A nested class is a class which is defined inside of another class. Just as we nest the conditional statements such as if...else, switch and loops in the same way we can nest classes in Java. It provides better encapsulation. The basic syntax of Inner class in Java is as follows: class OuterClassName { //code class InnerClassName { //code } } To create an object of the Inner class, the syntax is as follows: OuterClassName.InnerClassName inner = new OuterClassName().new InnerClassName(); Uses of Inner class - It can access private members of the outer class, which increases encapsulation. - It is better to create a class as nested when it needs to be used only by one class. - It makes our source code more readable and maintainable. Types of Nested Classes The different types of Nested classes in Java are: - Non Static Nested Class (Inner Class) - Method Local Inner Class - Anonymous Inner Class - Static Nested Class Non Static Inner Class A non-static nested class is also known as inner class which is just a simple nested class. It can access all variables of the outer class. If it is declared as private then it cannot be accessed by any other class except the class in which it is declared. In this example, we will create a class A which will have class B as an inner class. We will create a object of class A and try to class B constructor. Example Java code for A.java: //File name opengenus_A.java class opengenus_A{ private int a = 10; class opengenus_B{ public void print(){ System.out.println("a = " + a); } } } Java code for Main.java: //File name Main.java class Main{ public static void main(String[] args){ //this is the way of creating an instance of an inner class. opengenus_A.opengenus_B inner = new opengenus_A().new opengenus_B(); inner.print(); } } Output: a = 10 As you can see in the above example we have created a class B inside of class A and in B's print() method we are printing the value of A's private variable a. Method Local Inner Class When a class is declared inside a method then it is known as method local inner class. The scope of this type of inner class is only within the method it is declared. It can be instantiated only in the method it is defined. In the following Java code example, notice that the inner class B is a part of the myMethod() function of class A. It is local to that function. Example //File name opengenus_A.java class opengenus_A{ void myMethod(){ int a = 50; class opengenus_B{ public void print(){ System.out.println("a = " + a); } } opengenus_B b = new opengenus_B(); b.print(); } } Output: a = 50 Anonymous Inner Class An anonymous inner class is an inner class which is declared without any name. Like other anonymous classes we declare and instantiate it at the same time. Anonymouns inner classes are usefull for overriding methods. Follow the following Java code example to understand it better. Example //File name B.java abstract class opengenus_A{ public abstract void method(); } public class opengenus_B{ public static void main(String[] args){ opengenus_A a = new opengenus_A(){ public void method(){ System.out.println("Inside anonymous class."); } }; a.method(); } } Output: Inside anonymous class. Static Nested Class A static nested class is declated with the keyword static. Static classes cannot be called an inner class as they are just like other static members of a class. It cannot access the non-static variables of the outer class. Follow the following Java code example to understand it better: Example class opengenus_A{ static int a = 100; static class opengenus_B{ void print(){ System.out.println("a = " + a); } } } class Main{ public static void main(String[] args){ opengenus_A.opengenus_B b = new opengenus_B(); b.print(); } } In the above case we do not need to create an object of the outer class as the inner class is static and static members can be accessed without creating it's instance. Output: a = 100 If we create a static method inside of a static class then we can access it just like any normal static method of class. With this article at OpenGenus, you have the complete knowledge of Inner classes in Java and its different kinds. Enjoy.	https://iq.opengenus.org/inner-class-in-java/	CC-MAIN-2020-24	refinedweb	722	65.73

What is described here is equally applicable to the L<DynaLoader\|DynaLoader> interface.> A sufficiently complicated module using XS would have both Perl code (defined in F<YourPackage.pm>) and XS code (defined in F<YourPackage.xs>). If this Perl code makes calls into this XS code, and/or this XS code makes calls to the Perl code, one should be careful with the order of initialization. The call to C<XSLoader::load()> (or C<bootstrap()>) calls the module's bootstrap code. For modules build by F<xsubpp> (nearly all modules) this has three side effects: =over =item * A sanity check is done to ensure that the versions of the F<.pm> and the (compiled) F<.xs> parts are compatible. If C<$VERSION> was specified, this is used for the check. If not specified, it defaults to C<$XS_VERSION // $VERSION> (in the module's namespace) =item * the XSUBs are made accessible from Perl =item * if a C<BOOT:> section was present in the F<.xs> file, the code there is called. =back Consequently, if the code in the F<.pm> file makes calls to these XSUBs, it is convenient to have XSUBs installed before the Perl code is defined; for example, this makes prototypes for XSUBs visible to this Perl code. Alternatively, if the C<BOOT:> section makes calls to Perl functions (or uses Perl variables) defined in the F<.pm> file, they must be defined prior to the call to C<XSLoader::load()> (or =head2 The most hairy case If the interdependence of your C<BOOT:> section and Perl code is more complicated than this (e.g., the C<BOOT:> section makes calls to Perl functions which make calls to XSUBs with prototypes), get rid of the C<BOOT:> section altogether.

I have heard it and no it is not real but a fake or spoof. Jewel Palovak still holds the original tape and has no plans to release it. I hope that she never does. There is now a second fake version posted on UTube. The publisher of this latest UTube version stated to me in an email that he knew the audio he labeled as real, is in fact a fake. It was posted to draw traffic to his UTube page. All fake recordings so far have been under 3 minutes in length and the real tape is 6 minutes. As I reported above in my investigation the bear is nearly silent. Bears typically make very little sounds, and each fake recording has the sound of a bear roaring, growling, and making all sorts of noises. In movies, bear noises are dubbed in electronically.

horus934,333 Points EOF error in challenge, code runs fine in workspace So I saw another post regarding a similar problem that didn't answer my question so here's mine. "Create a function named square. It should define a single parameter named number. In the body of the function return the square of the value passed in." From what I could tell, and running it seems to do what the question's asking for. I created the function named square, defining only a single parameter named number, and return the square of the value passed in by the users input. Oddly it passes the first test ok, and the second one returns the EOF error. Maybe there's a different way it's wanting me to do things and I'm just misunderstanding the ask in this particular challenge? import math def square (number): return math.ceil(number * number) number = float(input("What number would you like to square? ")) squared = square(number) print ("Your number squared equals {}".format(squared)) 2 Answers Jennifer NordellTreehouse Moderator Hi there, horus93 ! I can see that you've worked hard on this and you're doing great. But keep in mind that these challenges aren't a full-fledged program. Treehouse is going to call that function and send in a number. They expect to get back the result of that number squared. Doing things like using an input will likely cause the challenge to break. Remember, there's no one on the other side to input anything. You've also printed out the result and formatted it neatly, but again, this was not asked for by the challenge. Doing things that are not asked for can cause the challenge to break even if they are functional outside of the challenge. Here's a list of things you will not need: - the import of the math library - math.ceil - a - an inputstatement You will also need to change the squared variable to result as asked for in the second step. In that step, you will send in a concrete number like 10 or 7 instead of trying to get the number from the user. Mainly, the problem here lies in doing things that are not asked for by the challenge. I feel like you can get it with these tips, but let me know if you're still stuck! horus934,333 Points Haha thanks, as usual I was over thinking things, and after a day of work I came home with my brain too tired to process things properly (for some reason I was scanning over the word "not" in your list of things I would not need, and just reading it as "Here's a list of things you will need", so basically slapping my head against a wall until I reread your post this morning and fixed the issue allowing me to continue onward and upward!

Do you want to transpose the input tensor? If yes then tf.transpose() allows you to do so. In this entire tutorial, you will learn how to implement TensorFlow transpose in python using different examples. Example on Tensorflow Transpose Before going to the examples part make sure you have properly installed TensorFlow on your system. Also, note that all the examples have been done on Jupyter notebook. So for better understanding, you should do the same on it. The syntax for the TensorFlow transpose is below. tf.transpose( a, perm=None, conjugate=False ) Here ‘ a‘ is the input tensor. The perm parameter allows the tensor to be transposed along the given axis. It defines the output shape of the transposed tensor. The parameter conjugate is true if the input tensor is of a complex type. Example 1: Simple Tensorflow transpose on input tensor In the example, I will create a simple input tensor and pass it to the tf.transpose() function. The output will be the transpose of the input array. The output will also be of tensor type. Run the below lines of code. import tensorflow as tf x = tf.constant([[10, 20, 30], [40, 50, 60]]) tf.transpose(x) Output Example 2: Transpose on input tensor using perm If you pass the perm parameter then it will transpose the input array according to the size defined. For example, I want to transpose as a 3×3 dimension then I will pass perm=[0,1]. Execute the below lines of code to transpose the tensor. import tensorflow as tf x = tf.constant([[10, 20, 30], [40, 50, 60],[70,80,90]]) tf.transpose(x,perm =[0,1]) Output Example 3: Transpose of Conjugate tensor The above examples were not for conjugate tensors. But in case the input tensor is conjugate then also you can transpose it. To do so you have to pass conjugate=True as an argument to the tf.transpose(). Let’s create sample conjugate and transpose the tensor. Execute the below lines of code and see the output. import tensorflow as tf x = tf.constant([[10 + 1j, 20 + 2j, 30 + 3j], [40 + 4j, 50 + 5j, 60 + 6j]]) tf.transpose(x,conjugate = True) Output There are examples of how to implement TensorFlow transpose.

AS3 Sprite added to Stage but not visible I'm trying to get a simple AS3 app up and running, and for some reason, I cannot get a sprite to show. At this point, all I want to do is get a red sprite to fill the stage. public class Main extends Sprite { public function Main():void { super(); stage.scaleMode = StageScaleMode.NO_SCALE; stage.align = StageAlign.TOP_LEFT; var square:Sprite = new Sprite(); square.width = stage.stageWidth; square.height = stage.stageHeight; square.x = square.width / 2; square.y = square.height / 2; square.graphics.clear(); square.graphics.lineStyle(3, 0xFF0000); square.graphics.beginFill(0xFF0000); square.graphics.drawRect(0, 0, width, height); square.graphics.endFill(); square.addEventListener(Event.ADDED_TO_STAGE, addedToStage); square.addEventListener(MouseEvent.CLICK, onClick); addChild(square); } private function addedToStage(e:Event):void { trace("Added sprite to stage"); } private function onClick(e:Event):void { trace("Got click on sprite"); } } The trace shows that the sprite was added to the stage, but nothing is displayed, and if I click on it, the onClick function never gets called. If I use a TextField instead of a Sprite, it displays just fine. There must be something weird about Sprites. What am I doing wrong? Thanks! Answers Trying to set the width and height for a empty Sprite will return 0. Have a look at here. and Refer Mr.Marty Wallace's answer. Your issue is here: square.graphics.drawRect(0, 0, width, height); The values for width and height in this line are 0. The reason being that they are referring to the width and height properties of the class you're working within (Main - properties inherited from DisplayObject) which will be zero based on what I can see. You're essentially saying: square.graphics.drawRect(0, 0, 0, 0); Which will render nothing.

I've done a lot of searching about casting an object in Ruby, and can only find examples of casting a string to an integer or vice versa. I'm curious how to cast other, more complex objects.. For Example with these classes... class Animal attr_accessor :weight, :name end class Duck < Animal def speak 'Quack' end end irb> animal = Animal.new irb> duck = (Duck)animal irb> duck.speak => "Quack" An object in Ruby is created with a particular class and it will be destroyed with the same class, it never changes. You can't cast, either, all you can do is call functions which convert, a process that involves creating a new object or using another as a proxy. In your case you can't cast, but you can create a duck with identical properties: class Animal attr_accessor :weight, :name def initialize(options) # Allow calling new with either an options hash, or another # animal that's intended to be cloned. case (options) when Animal @weight = options.weight @name = options.name when Hash @weight = options[:weight] @name = options[:name] end end end class Duck < Animal def speak(phrase) '%s says %s' % [ name, phrase.inspect ] end end animal = Animal.new(weight: 10, name: 'Bill') duck = Duck.new(animal) puts duck.speak('quack!') A second option is to move the duck-like functionality to a separate module you can mix-in: module ActsAsDuck def speak 'Quack!' end end animal.extend(ActsAsDuck) puts animal.speak That mixes in any methods in that module into your object instance.	https://codedump.io/share/PkZQYvwRiwZw/1/ruby-class-ineritance	CC-MAIN-2016-44	refinedweb	253	58.69
hi, hi, An unanswerable question is why is it 'bool' and not 'bool_t' to match <stdint.h> types? Inconsistencies like this are annoying. stdbool.h defines bool as a macro because the C standard 7.18 stdint.h defines intN_t as typedefs because the C standard 7.20 You can use one or the other to achieve the same effect, but it's better to use the proper one to your needs, you need to consider the compatibility of the your project. Regards Daniel. The point is 'bool' is used as a type, it should end with a _t. The heading of 7.16 clearly states 'bool' is a type: "7.16 Boolean type and values". By convention macros in C are upper case then by 7.18 it should be BOOL, or properly BOOL_T. We may be looking at different version of the standard as the one I'm looking at has 7.20 as: 7.20 General utilities <stdlib.h> Hi yang, 'bool' is not a keyword in the C programming language. To use it, make sure you include stdbool.h: #include <stdbool.h> in your sources. I hope this helps, Erich	https://community.nxp.com/thread/490970	CC-MAIN-2019-39	refinedweb	194	87.31
NEW: Learning electronics? Ask your questions on the new Electronics Questions & Answers site hosted by CircuitLab. Microcontroller Programming » compiling a .c file i need to write a program with both a millisecond delay and a microsecond delay. i figured out with a changed value in the provided millisecond delay function of the libnerdkits i could get the desired microsecond behavior. i hoped i could then just save this .c file with a new name ( udelay )and it would create a corresponding udelay.o ( object ) file. i read in another thread that the normal compile of a program automatically runs the make file in the libnerdkits. when i do this i get, however, no created udelay.o file created. can anyone help? Or you could just use delay_us(); instead of delay_ms(); Rick sure. well, it looks to me that the ms delay is built on the us delay function anyway, but that does not solve my problem. i need this to put this seperate function in the libnerdkits folder. this is what i do not know how to do. You are correct, delay_ms is built on delay_us. But you lost me as to what exactly you are trying to achieve. If you want to use delay_us or delay_ms, all you have to do is include ../libnerdkits/delay.h in your programs and both would be accessable. If you are having problems compiling a library from a copy you modified, that would require a change in the makefile. For instatnce. Say you make a change inside one of the funtions in the delay library (without adding or changing names of functions) then save it to a file called mydelay.c You would also need to copy delay.h to mydelay.h. Then in the makefile, change the reference of ../libnerdkits/delay.o in the LINKOBJECTS to ../libnerdkits/mydelay.o Then your file will compile with your program. Keep in mind, you will also need to change the include in your program for your custom delay file. just to explain the reason for two delays. i need a 30 micro second hi output. with the provided millisecond delay, i was unable to achieve such a short time. after changing a variable in the millisecond delay's .c file, i was able to get my 30 microseconds ( i am checking with an oscilliscope). between the high outputs i need it to stay low in the millisecond's range. the altered .c file did not cooperate, however. it appears less than 1 millisecond in the millisecond delay is a problem and more than 1000 microseconds in the microsecond delay is a problem. i read something on .h files and thought it would not be necessary for what i was trying to do. i will digest your info. and let you know the my results... good or bad. thanks -dave A little while back I had need for an improvement over delay_ms and delay_us and I put together this web page to create accurate timing loops. To use it in C, surround the results with "asm volatile". For example, to generate a 30us loop, go to the web page, enter 14.7456 as the CPU speed (for NerdKits crystal), 30 as the delay, press the "us" button, and it generates this: ; Delay 442 cycles ; 29us 975 25/576 ns ; at 14.7456 MHz ldi r18, 147 L1: dec r18 brne L1 nop To turn this into C code, make some minor tweaks to get it to work with the "asm" statement syntax: asm volatile ( " ldi r18, 147" "\n" "1: dec r18" "\n" " brne 1b" "\n" " nop" "\n" ); I'm planning on having the web page do that automatically at some point. It handles long delays quite easily. Here's a one-second delay for example: asm volatile( " ldi r18, 75 " "\n" " ldi r19, 206" "\n" " ldi r20, 238" "\n" "1: dec r20 " "\n" " brne 1b " "\n" " dec r19 " "\n" " brne 1b " "\n" " dec r18 " "\n" " brne 1b " "\n" " rjmp 2f " "\n" "2: " "\n" ); hey bretm, i have been away from my nerdkit for a while, but just plugged in your delay code. works! awesome. thanks man. I have found the delay functions that are included with avr/gcc are quite accurate and as long as you define F_CPU to reflect your clock frequency, they self-adjust. I wonder why the nerdkit folks wrote their own in libnerdkits? They're in the util directory ... #include <util/delay.h> functions are _delay_us(?) and _delay_ms(?).

Switches in a cell in a table view Is there any way to put switches in a cell in a table view? @techteej Yes. I've just made a SettingsSheet class that does that and reads/writes the settings from a plist embedded in the .py file You need to subclass ListDataSource and then you can build the cells yourself. @tony There doesn't happen to be an easier way? @techteej The documentation talks about implementing your own datasource from scratch and there's a few examples of that around. Hopefully though, it's simpler to just subclass the existing ListDataSource. Don't be put off, it's not too hard. There's only one method to override, the one that builds the row... and 2 lines to make the cell, 6 the switch. @techteej Here's a little test harness that will let you run the class above... paste it after the class and move the import to the top. Of course you'll get an error if you switch the switches because there's no plist in this little harness... but if you see it working you might be encouraged... import ui tv = ui.TableView() lds = SettingsSheetDataSource([{'setting' : 'Setting 1', 'value' : 'On'}, {'setting' : 'Setting 2', 'value' : 'On'}]) lds.tableview_can_delete = False tv.data_source = lds tv.row_height = 50 tv.allows_selection = False tv.present('sheet') _swA()throws AttributeError: 'NoneType' object has no attribute '_pl'. Also, setting the "value" to True or False instead of 'On' or 'Off' simplifies the logic. @ccc Did you read the comment with the post...

Odoo Help Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps: CRM \| e-Commerce \| Accounting \| Inventory \| PoS \| Project management \| MRP \| etc. Which method is executed when clicking on trash icon in tree view I am using odoo 9. I am working in a view with a one2many field. The one2many field tree view list, there is a trash icon on the left of each row. When I click on the trash icon, I would like to intercept record deletion and perform some custom action. I tried to override unlink method but it does not break into the break point set inside the unlink so I think odoo is not calling unlink. Any idea? The view is view_pack_operation_lot_form. Here is my method: @api.multi def unlink(self): res=super(myclass, self).unlink() # do my stuff return res It is not clear from you question whether you are calling the Unlink method of Child or Parent object. Anyways In case of One2many, Deleting depends on the record's storage mode, i.e deletion upon saved lines (physical records) deletion upon unsaved records (cache records) Hence when you calling Unlink method of Child Object, this will work well w.r.t Physical Records, but not on Cache records, which are not saved to the database. So the alternate solution would be to deal with the One2many field values which you will receive in the Write Values of Parent Object. Sorry, originally I put the unlink method in the child class (stock.pack.operation.lot) which I realize is not correct. It should be in the parent class (stock,pack.operation). So I override the parent (stock.pack.operation) unlink method. Upon deleting the row, it still does not trigger the parent class' unlink method. In my case, it is the cache scenario since the rows are not saved yet. I cannot wait until "write" is called when clicking on the "Save" button though since I need to perform some operation on the cached rows before saving to the db. I would like to know which method is called when the trash can icon is clicked. Then I can try to intercept and override that, I cannot locate the codes in the source.
