jQuery UI Highlight new <li> with bullet point
I have an ajax list that updates (as notifications). However, what I'm trying to do is jQuery UI Hightlight to show a new `<li>` that is appended to the `<ul>...</ul>`. The `<li>` however has a image bullet point which disappears for the duration of the highlight. Is there any way to highlight the entire `<li> ... </li>` include the bullet point itself. What I assume happens is a background is added to the `<li>` for the duration of the hightlight which then overrides the bullet point background. **jQuery** `$(data).hide().prependTo("ul.notifications").fadeIn("slow", function() { $(this).effect("highlight", {}, 3000); });` Thanks :)

Tortoise client on VisualSVN server
I've been trying to figure out how to browse the root of the server using the Tortoise svn 'Repo browser'. When I go to the root, it doesn't list any folders, and I just get a message, OPTIONS of 'http://example.com:8443':200 OK (http://example.com:8443) Rather than a full list of the folders on the server. I've had a quick poke around on the Visual SVN site and I can't see anything for this. I spend way more time in my project's in Explorer than I do opening new tabs for browsing a server in my browser, just to paste it back into my svn client. Can anyone point me in the right directions please?

overloading operator >>()
My knowledge of C++ is small as I have only taken a couple classes. I undersand the basic case of using a friend function to overload the input, output stream operator for the "simple book example" of a Point object that has x, y instance variables. I am looking at a real project now, trying to understand what someone wrote and am getting the error: error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'const char [2]' (or there is no acceptable conversion) 1> c:\program files\microsoft visual studio 9.0\vc\include\istream(1000): could be 'std::basic_istream<_Elem,_Traits> &std::operator >><std::char_traits<char>>(std::basic_istream<_Elem,_Traits> &,signed char *)' [found using argument-dependent lookup] 1> with 1> [ 1> _Elem=char, 1> _Traits=std::char_traits<char> 1> ] Noob question (1), can someone explain what basic_istream is? The error points to: template<class _Traits> inline basic_istream<char, _Traits>& __CLRCALL_OR_CDECL operator>>( basic_istream<char, _Traits>& _Istr, signed char *_Str) { // extract a signed char NTBS return (_Istr >> (char *)_Str); } The other part the error points to is: void input(std::istream &in = std::cin) {in >> "(" >> X >> "," >> Y >> "," >> Z >> ")" ; } inline friend std::istream& operator >> (std::istream& in, Coord &val) {val.input(in); return in; }; Not sure what the error is looking at with my limited knowledge. It seems to be complaining about not the right type in the inline friend std::istream& operator>> function because of something wrong in the basic_istream template (which I'm not sure what is happening there). Any advice would be greatly appreciated. Thanks!

javascript loading conditional statement
I've been struggling for days with getting rid of an error in IE, and to 'almost' no avail. I just tried loading jquery 1.2.6 instead of 1.3.2, and the error has gone away (though the site is noticeably slower now). However, I suspect I may be stuck with this solution. Is there a browser based way to include the script similar to the css conditional statements? I can do it serverside if I need to, but client-side would be nice.

How do I bottom margin words in a left column whenever there is a ul in a right column?
Right now I have an html setup where there is a top space with two column divs below. I am kind of new to css, and I want know if there is any way to bottom margin the words in the left div whenever there is a ul in the right div. Here is the html: <div id="resume"> <div id="heading"> </div> <div class="resume-section"> <div class="left-col"> <p>word</p> </div> <div class="right-col"> <ul> <li>something</li> <li>something</li> </ul> </div> </div> </div> I have tried .resume-section > .left-col < .right-col > ul { margin-bottom:200px; } and .resume-section > .left-col , .right-col > ul { margin-bottom:200px; } and nothing happened. Any suggestions on how I can do this? I'll post a jsfiddle if you request one.

Huge scale MySQL database for stats storage - what do you recommend?
A project I am busy on now requires many different kinds of stats, most notably number of visits/views to a product detail page for a specific period of time. This would of course require storing each visit in a table, e.g. id | visit_date (which will be a UNIX_TIMESTAMP()) | product_id | ip_address (for country-related stats) This way stats can be generated per product and for a selected time-frame and (using a DB like MaxMind GeoIP) per city/country as well. Only problem is this table will fill with millions and millions of records very quickly. Any recommendations on how I should approach this the most efficient way?

Best strategy for custom profile properties in MVC 3
I need to implement some (maybe 10) custom properties for logged in users for my MVC3 vb.net web app. These will define how certain data is displayed within my views. I can think of a couple of possible solutions.. 1 - Session variables. Will do the job but seems a bit untidy, and can't be strongly typed 2 - custom properties of the current user object; is that even possible? 3 - Custom profile provider. Looks like it might be a good option. Has anyone got any tips on what worked well for them? I already have custom membership and role providers that are working fine. Thanks!

Inventory Management System in 3 Hours?
**Inventory Requisition Process:** Whenever a user requires inventory, user generates an inventory requisition, and if the inventory is available, the inventory will be directly issued and user’s inventory account will be updated. In case the inventory is not available, the purchase order will be generated for the required inventory to the corresponding vendor and sent to the vendor. Once the purchase order is received back, it will be updated as per the received inventory items. Finally the payment of the purchase order will be made. Hence the inventory will be updated accordingly. Once the inventory becomes available, based on inventory requisition, it will be issued to the end user, and the user’s inventory account will be updated. ---------- **Test Requirement:** On the basis of Inventory Management System, business process, and system design provided to you, you are required to develop “Inventory Management” and “Purchase Order Management” modules. You can use language of your choice for developing the given system. **Inventory Management Module:** Inventory Management Module handles the inventory requisition, inventory issuance, and inventory stocks maintenance. **Purchase Order Management Module:** Purchase Order Management Module handles the purchase order generation and purchase order receiving. ---------- **My Question**<br> What will be strategy you use to develop this type of application in 3 Hours to achieve target. 1. **Application Type** <br>Asp.net Application or Winform Application 2. **Architecture** <br>Should we make proper classes for all entity and then work on it? and stored procedures. Or just working on controls value and pass run time SQL quires? 2. **Database Design** <br>What would be the ERD of this Application? 2. **Reference Material** <br>Please give reference of materials where i can demo online these modules?

Access denied for user 'root'@'localhost' (using password: YES) Works sometimes rails
I have a couple of versions of a project that run with mysql2. I have a version on my desktop which works fine. However i uploaded it on svn and that also works. After a colleague of mine added some css files now it stopped working. It gives the above error. Previously i had problems with passwords etc which gave the same error which i resolved. Now the version on my desktop alone works however the source controlled version is not working. Any idea where i should check for any problems? I also added a mysql dump file into the project folder.

I have a version on my desktop which works fine. However i uploaded it on svn and that also works. After a colleague of mine added some css files now it stopped working. It gives the above error. Previously i had problems with passwords etc which gave the same error which i resolved. Now the version on my desktop alone works however the source controlled version is not working. Any idea where i should check for any problems? I also added a mysql dump file into the project folder.

ActiveAndroid, db4o, Ormlite — which one to use?
I wonder if someone could share his experience of using these db frameworks for ORM in Android. Let's try to find a winner!

Are there anything like Facebook game platform where users from the website can play multiplayer games developed by third party developers?
I would like to also know the complexity or any tips for building such a system. I would like to create a game platform website and just create a user community around it and leave the app developers create short simple multiplayer games. The user community from my platform(which would be a website) would be able to play these third party developer games with and against one another. Any suggestion or reference of such existing systems would be of great help.

Pygame move object position from one point to another at constant speed
I have a bunch of objects at different coordinates, and I need to animate them moving to another coordinate ie. one object is at coodinate (234,30) and I need it to go to (310,540). How do I do this in pygame? I tried messing around with slope and stuff like that but I couldn't get my object,s position to smoothly go there. Thanks.

Helpful snippits?
I'm a relatively new coder, and I'm looking to increase my snippits library. What are some of your most used snippits? I'm mainly looking for ones that I might not have thought about until I've had more experience, but will make me more productive. Have a snippit that is particularly clever? Post it!

Is there a per-method cost to object instantiation in Java?
I am hearing from another developer that an object is too expensive to instantiate repeatedly because "it has a bunch of methods." My understanding (from Bloch, mostly) was that object creation is costly mostly through things done explicitly in the constructor, especially creating other expensive objects. Is there a per-method cost for a new object in Java? I'm thinking not, but I need references if anyone has them. Thanks!

Castor Generated Classes (XML Marshalling) - XSD Unavailable
I recently moved to a project where I noticed there have a specific requirement to store some data as XML. The prior team used Castor generated classes to Marshall and Unmarshall the data. I have a new requirement now that requires me to add some additional (yet optional) fields to this XML. However I realized the prior team supposedly never checked in the XSD at all and I have no way to reach out to them. The XSD for sure was large and complex since it is responsible for generating around 50 classes. So writing the XSD again is going to be error prone and also a risk that I might end up creating XMLs now that are in compatible with the old XML. The other alternative I thought of was using a tool like XML Spy and try to reverse engineer the XSD from the XML, however that sounds a bit difficult too since I will need to reverse engineer 20 odd XMLs to generate XSDs and then merge all these XSDs into one, since the XML had several optional sections. There is still an element of error possible in this approach. The best option I can think of is reverse engineering the classes to an XSD - however Castor supposedly does not support this feature. So I don't have the means to convert these Castor generated classes back to an XSD! While the classes generated by Castor do have some Castor specific methods, in essence they are Pojos if the Castor specific methods are ignored! Do we have any suggestions here for getting or generating the XSD from java classes? Do we have any other suggestions to solve the issues I discussed? Thank you.

C# program to track in which drive it should be installed and keeping a track
I have an issue. could not resolve it So posting it here. Actually when any installation goes on it will asked to the user in which drive we should install. So it installs there and keeps a track of where it got installed. So in the same way i wish to ask the user by a C# program in which drive he wants to keep a file and later I should be able to track it. I mean to Say suppose the user installs in C drive later he uninstalls it and installs in D drive. I wish to know in which drive it is being put not by searching but in any other way. Like a registry or so which i can check where it is and get the details from it. Kindly help me. Thanks, Sindhu

Not sure what type of Excel formula (SUM, SUMIF ect...) to use for my calculation, can you get me going in the right direction?
In Excel Formulas there are so many different functions, that I am not sure which to use to get started. So if I were to give you an example could you point me in the right direction for learning what I need to do? Ok so say you want 6 Apples (D3) And you want 3 oranges (D4) (also buying 1-7 apples gets you 1 orange free so they only need to pay for 2 oranges but if they buy 8-14 they get 2 oranges free and if they buy 15-21 they would get 3 oranges free and so on and so on. multiples of 7 apples get you a free orange) And 5 grapes (D5) (these are sold by the 3, so no matter if you buy 5 you get charged 2 because these are only sold in 3's) And 4 Bananas (D6) (sold by the each) So is there a way to formulate this and make it all be one price in I3? The prices are D3=E11, D4=E12, D5=E13 and D6=E14 but for some reason it will not pick anything up past D4=E12, the code stops changing colors when I am putting in the formula. Not sure if this makes any sense so any help you can give would be greatly appreciated!

Rails 3 / Ajax - Turning link_to into a Jquery link
I'm attempting to change a hyperlink into a ajax link. That way I can link to an external target while updating model data without having to send the user to a custom controller action to handle a post/redirect. My application is a basic image gallery, each image links to an external website: Here's my partial _pictures.html.erb: <% @galleries.each do |g| %> <% for image in g.images %> <div id="picture"> <%= render 'top_nav'%> <%= link_to g.source, :target => true do %> <%= image_tag image.file_url(:preview) %> <% end %> <%= will_paginate(@galleries, :next_label => "Forward", :previous_label => "Previous") %> </div> <br /> <div class="image_description"> <h2> <%= g.title %>, <span class="time"> <%= distance_of_time_in_words(g.created_at, Time.now, include_seconds = false)%> ago </span> </h2> </div> <% end %> <% end %> Which is rendered on my index.html.erb: <h1>Share and click images to unlock more...</h1> <div id="galleries"> <%= render 'pictures' %> </div> I believe I've been able to change the link into an ajax link with the follow in application.js: $(function() { $("#picture a").live("click", function() { return false; }); }); As the link_to doesn't work (which I expected). Now, I'm trying to write the handler(not sure if that's the correct word) in the index.js.erb, I know this is way wrong, but what I've pieced together is: $("#picture").html.("<%= escape_javascript(render)("pictures")) %>") How do I get this link back working, but with via javascript? And if I wanted to make an ajax call to a model method, where would I begin writing that code, in application.js or index.js.erb? Obligatory defense mechanism: I suck at javascript.

CherryPy always returning HTTP 200
I'm having a bit of a problem when browsing to a non-existent resource. I get a response code of 200 instead of 404. I'm using the MethodDispatcher and I have a class that overloads the __getattr__ method to instantiate a resource if a child exists or to return AttributeError if one doesn't. My class is always returning the AttributeError correctly, but the data I actually get is always from the last good resource. Here's a simplified (except for __getattr__) version of my class: class BaseResource(object): exposed = True def __init__(self, name): self.children = [] # Pretend this has child resources def __getattr__(self, name): if name in self._children: uuid, application, obj_type, server = self._children[name] try: resource = getattr(app[application], obj_type) except AttributeError as e: raise cherrypy.HTTPError(500, e) return resource(uuid) else: raise AttributeError('Child with name \'{}\' could not be found.'.format(name)) def GET(self): cherrypy.log.error('*** {} not found, raising AttributeError'.format(name)) return 'GET request for {}'.format(self._name) So fetching I get the following when I browse to the following resources: http://localhost:8000/users - This resource exists, so it returns it correctly. http://localhost:8000/users/fake - This returns the "users" resource giving an HTTP 200. http://localhost:8000/users/fake/reallyfake - This returns the "users" resource again. So my question is, where can I start looking to find out why my code isn't returning a 404 for a non-existent resource. I'm sure I've done something wrong, but I'm not sure what.

How to remove cloned git repo from a second git repo?
I accidentally added a cloned git repository to a working copy clone of my repository, and pushed the changes to my remote. I did not use git submodule to do that, but rather did something like "git add somedir.git". Now whenever I clone my repo, I get an empty "somedir.git" directory. I cannot do a "git rm -r somedir", because git complains "somedir.git is a directory". How can I get rid of this directory or convert it into a proper submodule? The directory is completely empty after cloning, not even a .git/ folder in there.

Restrict method access to a specific class in C++
I have two closely related classes which I'll call Widget and Sprocket. Sprocket has a set of methods which I want to be callable from Widget but not from any other class. I also don't want to just declare Widget a friend of Spocket because that would give Widget access to ALL protected and private members. I want to restrict Widget's access to only a specific set of methods. One solution I came up with is to create a nested class inside Sprocket that contains wrappers for these methods and make Widget a friend of this nested class. For example: class Sprocket { public: class WidgetInterface { friend class Widget; WidgetInterface(Sprocket* parent) : mParent(parent) {} private: void A() { mParent->A(); } void B() { mParent->B(); } Sprocket* mParent; }; private: void A() { ... } void B() { ... } }; class Widget { public: Widget(Sprocket* sprock) : mSprocketIface(sprock) {} void doStuff() { mSprocketIface.A(); } // Widget can call Sprocket::A() private: Sprocket::WidgetInterface mSprocketIface; }; This results in some code duplication because the method signatures are now declared in two places, but it works. But now suppose I want to add a subclass of Widget called SpecialWidget and I want that class to also have access to the Sprocket methods. I can simply add this new class to the Sprocket friends list or I can add yet another set of protected wrappers in Widget that SpecialWidget (and any other subclass) can access but you can see that this is now becoming a maintenance issue. I don't want to have to update the friends list or the wrappers if I add new classes or change the method signature. If I use the "add another set of wrappers" approach, the method signatures will be duplicated in three places! Does anyone know of a simpler, cleaner way to do this?

function to submit forms one after the other
Can someone help me please. I have the following (simplified) code. function save_all_des(){ document.getElementById("form_zoom1").submit(); document.getElementById("form_zoom2").submit(); } I am submitting two forms, which have input of the same names but with different values. Individually they submit ok. Also in IE9 they submit correctly when called as shown. However in FF only the second works. It appears that the second is submitting over the first. I've tried using separate functions but they too seem to run at the same time. How do I make sure the code behind the form submittal is fininshed before the second submission? I have used jquery a little but I don't know how to use callback and ajax (yet). Any help appreciated. Thanks

Can an Android app running on a WiFi hotspot-enabled phone 'see' the LAN?
I have a phone that's capable of being a WiFi-hotspot. Our sporting group has an application that runs on both Android and iOS and can talk to each other over a WiFi access point (the IP of the device is displayed, and that IP address is entered into any other device that wants to talk to this device. They're all on the same subnet, and don't need internet access, they just want to talk to each other). We frequently use the phones as WiFi hotspots, and everything works EXCEPT for if the application is brought up on the phone that has the WiFi hotspot enabled -- Then it thinks there's no WiFi available. The question is: Can an application that's running on the WiFi hotspot-enabled phone use the LAN at all, or can it only 'see' the WAN interface?

Django - converting URL into links, images, objects
I'm creating simple comment-like application and need to convert normal urls into links, image links into images and yt/vimeo/etc. links into flash objects. E.g.: http://foo.bar to <a href="http://foo.bar">http://foo.bar</a> http://foo.bar/image.gif to <img src="http://foo.bar/image.gif"/> etc. Of course i can write all of that by myself, but i think it's such obvious piece of code that somebody has already wrote it (maybe even with splitting text into <p></p> paragraphs). I was googling for some time but couldn't find anything complex, just few snippets. Does filter (or something like that) exist? Thanks! PS. There is urlize but it works only for the first case.

How to apply software development learning
Apologies if the question seems a little vague, ill see if i can clarify. Im approaching the end of my CS course at university and im beginning to look at jobs, however im running into a problem that i suspect applies to a lot near graduates. Over the past 3 years ive learnt how to do lots of very clever things; the principles of OO programming, project management, systems analysis etc, but if i went into a job tomorrow tomorrow, and was told "write an application that does x" i wouldnt know where to begin. I feel like ive got a lot of very useful skills and knowledge but no idea how to pull it all together. What i want to know is how did everyone go about overcoming this hurdle, are there any particular routes to take? any career paths that help with this problem in particular, or is it simply experience? Any suggestions would be greatly appreciated and im sure would be of assistance to anyone else in my position that comes across this thread.

How do I count the number of instances from 2 columns where a given string appears?
Here's an example table: games_table ---------------------------------------------------- | home_team | away_team | game_outcome | ---------------------------------------------------- | Chelsea | Arsenal | Home wins | ---------------------------------------------------- | Everton | Liverpool | Away wins | ---------------------------------------------------- | Arsenal | Chelsea | Home wins | ---------------------------------------------------- What I need is the number of times 'Chelsea' appears WHERE the game_outcome = 'Home wins' which is 2 in this example. Normally this would be very easy but I'm stuck because I have to search 2 columns. I really need some insight. This is in SQL-Server 2008.

MS future .net P/InVoke Android Delphi c++ price compertition
Today C# and a modern copy of Delphi is getting very expressive for a student /hobbyist to start out on with a $2,000 price tag to get started. I remember when you could get started at a 10th of the price with Delphi. And a very large array of small programs came about in all sorts of fields. The ones that come through that hobby level are ether working for people or people that have marketed their own product. Now we have P/Invoke as our future and MS plays the big daddy and markets it self. And thinks every one will tag along as little puppies. The truth is they are trying to set a standard that with out us tagging along MS will be in problems. At the same time MS has to address the future and as programmers Android devices will be 60% of the future world market and students will take them up fast. Why 1/ portable 2/ they communicate for the student in many more ways. 3/ price. As MS sales have dropped in resent years they will drop further and apple shears man are they about to fall real bad. To me windows XP will hang on because future sales will drop and I find average person thinks XP is complex enough to maintain !!!!!!!!!!!!!!!! And yes there is the power gamer out their and computers have just gone over the 4 gig barrier to 8 gig. But the least leap in size is wasted because of .net P/invoke with ANSSI and 64 bit pointers effectively using twice the space. 90% of users do not use 0.5 of a gig of memory and 70% of all users use English. There is clearly a limit to IBM programming power as proce4ssors only go so fast!!!!!!!. Android devices are using UTF-8 that is not supported by MS properly. UTF-8 is an extension of ACSSI that is so compatible with Delphi and those other languages, So I want to suggest this. Create and market a freeware Delphi *.Dll called D/Invoke!!!!!!!!! 1/ UTF-8 to ACSSI interfacing. 2/ 32 and 64 bit platform for old XP computers and users that will never use more than 4 gig memory space. 3/ Write the Dll in Delphi that its not C++ compatible that .net cannot interfere with the standard. And a future consideration is communication with the Java JNI for Java communication. 4/ Create freeware code that links with Delphi 3 to Delphi 6 as some projects out already have done some work. Except in the area of threads. In may ways many projects will just need recompiling once everything in this project is sorted. Then all projects made with D/Invoke will run faster than .Net, use the best text system UTF-8, Be Future proofed better than .net, communicate to important languages like Java. And students can learn to develop at cheaper prices producing a big development base again. What do people think!!!!!!!!!!!!!!!

CSS positions image in centre of screen in all browsers but IE
I couldn't find a similiar question in the related questions section, so figured I'd try my luck. I'm designing a page where the load time will noticeably long enough to where a loading icon could appear. Currently I have it set so that the icon displays in the center of the screen, with a translucent overlay over the page until page load is complete. Here's the code that I am using <style type="text/css"> #overLayBackground{ background-color: rgb(250, 250, 250); opacity: 0.7; /* Safari, Opera */ -moz-opacity:0.25; /* FireFox */ filter: alpha(opacity=70); /* IE */ z-index: 200; height: 100%; width: 100%; background-repeat:repeat; position:fixed; top: 0px; left: 0px; text-align:center; line-height: 240px; } #overLayBackground>img { position:absolute; bottom:0; top:0; left:0; right:0; margin:auto; } <div id="overLayBackground"> <img src="www.example.com/images/loading.gif" title="Image" alt="The image" /> </div> </style> Now this works as expected in Firefox and Chrome, but IE has the icon showing in the top left hand corner. Is there a way to have it behave as the other browsers and position it in the center of the screen? Thanks in advance.

I am building an applicaiton using asp.net mvc3. I added two layers to this project, repository and service layer. some of my code, I am not sure which layer I should put them in. on my register page, to create an account, I only ask user to enter their email and password. before I add it to the database, my user table need more info. I need to add: user.ip= "1.1.1.1"; user.createddate="11/11/1911"; .... so above code, where should I put them? webui, repoistory or service layer.

Generic interface for photocopiers - where to begin?
This is a slightly curly one. I have a need to connect (either by network, or direct cable) to a variety of photocopiers (all different brands and models) and to retrieve digital copies of anything that gets photocopied (a great start would be to detect that a copying event is taking place). I have literally no idea where to begin. What technologies should I be investigating to achieve something like this? I'm 100% sure that I'll need to implement different methodologies for each brand, and I'm prepared to discover that most machines are locked up quite tightly so this may be a fruitless endeavor. Any assistance would be appreciated!

MySQL: Limit rows linked to each joined row
**Specifications: MySQL 4.1+** I've certain situation that requires certain result set from MySQL query, let's see the current query first & then ask my question: SELECT thread.dateline AS tdateline, post.dateline AS pdateline, MIN(post.dateline) FROM thread AS thread LEFT JOIN post AS post ON(thread.threadid = post.threadid) LEFT JOIN forum AS forum ON(thread.forumid = forum.forumid) WHERE post.postid != thread.firstpostid AND thread.open = 1 AND thread.visible = 1 AND thread.replycount >= 1 AND post.visible = 1 AND (forum.options & 1) AND (forum.options & 2) AND (forum.options & 4) AND forum.forumid IN(1,2,3) GROUP BY post.threadid ORDER BY tdateline DESC, pdateline ASC As you can see, mainly I need to select dateline of threads from 'thread' table, in addition to dateline of the second post of each thread, that's all under the conditions you see in the WHERE CLAUSE. Since each thread has many posts, and I need only one result per thread, I've used GROUP BY CLAUSE for that purpose. This query will return only one post's dateline with it's related unique thread. **My questions are:** 1. How to limit returned threads per each forum!? Suppose I need only 5 threads -as a maximum- to be returned for each forum declared in the WHERE CLAUSE 'forum.forumid IN(1,2,3)', how can this be achieved. 2. Is there any recommendations for optimizing this query (of course after solving the first point)? **Notes:** I prefer not to use sub-queries, but if it's the only solution available I'll accept it. Double queries not recommended. I'm sure there's a smart solution for this situation. **Appreciated advice in advance :)**

How to print like a chart JAVA HELP PLEASE RELATIVELY EASY!!!
I have almost this entire calendar project I'm doing finished, but need help printing out the days under the months in a chart format. The chart has to look like this if you don't get what I mean: Sunday Monday Tuesday Wednesday etc. 1................2............3.............4....................................................................................................................5................6...........7..............8 etc. (Without all those dots I put in) The months don't have to go in a chart or anything, just the days. So anyways there are two classes, calendar and months. Calendar is finished and 100% correct because it was given to us completed by the professor, and he said not to change anything. I'm almost done with months but need a little help. Here's the completed class calendary which doesn't need to be changed: import java.util.Scanner; public class Calendar { static final int FEBRUARY = 2; static final int MONTHS_PER_YEAR = 12; static int [] daysPerMonth = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}; static String [] months = {"", " Januray", "February", " March", " April", " May", " June", " July", " August", "September", " October", "November", "December"}; public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Enter the year? (yyyy): "); int year = in.nextInt(); int firstDay = firstDayOfYear(year); // February: Check for leap year daysPerMonth [FEBRUARY] = isLeapYear(year) ? 29 : 28; for (int i=1; i <= MONTHS_PER_YEAR; i++) { Month month = new Month(daysPerMonth[i], firstDay); System.out.println("\n\n "+months[i]+" "+year); month.printMonth(); firstDay = month.getFirstDayOfNextMonth(); } } private static boolean isLeapYear(int year) { return ((year%4 == 0) && (year%100 != 0)) || (year%400 == 0); } private static int firstDayOfYear(int year) { return (2 * (13) + (3 * (13+1)/5) + (year-1) + ((year-1)/4) - ((year-1)/100) + ((year-1)/400) + 2) % 7; } } So don't worry about that to much except for what to call. The second thing I have to do is my months class. I believe it's mostly working, except for the printMonth method in the Month class. Here's the Month class: public class Month { public int daysPerMonth; public int firstDay; public Month(int daysPerMonth, int firstDay){ this.daysPerMonth = daysPerMonth; this.firstDay = firstDay; } public int getFirstDayOfNextMonth() { int nextDay = firstDay + 1; for(int i = 0; i < daysPerMonth; i++) { if(firstDay + 1 > daysPerMonth - 1) { nextDay = 0; } else { nextDay++; } } return nextDay; } public void printMonth() { String [] days = {"Sun", "Mon", "Tues", "Wed", "Thurs", "Fri", "Sat"}; System.out.println(days); } } As of right now, the output always has the months come out correctly but then under every month it will say something wierd like: [Ljava.lang.String;@14318bb , or some other weird output that I don't get why it's doing. Also, I think I messed up something with the getFirstDayOfNextMonth class not sure how though. THANK YOU SO MUCH FOR ANY HELP, I'M NOT SAYING DO THE WORK FOR ME BY ANY MEANS, BUT HELP WOULD BE GREATLY APPRECIATED

Advanced Postgres resources?
I have been using Postgres for almost a year now and I've been able to accomplish all the tasks at hand so far by googling what I need. I'm looking for a good Postgres resource so I can discover things that are possible aside from just querying and maybe to learn things beyond what I need (or I didn't know that I needed). Of course, it should be Postgres specific.

i have created a webservice [.asmx] file. This web service will actually get a string as Input and insert the values to database. Now this webservice will be called by another application, so they are asking wsdl file from me to access consume this webservice. I know that, wsdl can be created via cmd to generate a .cs or .vb or .dll files And there is also a xml generated when i user ?wsdl along with my URL But i am confused which one to provide ??!!!

Should we avoid turning on warnings for the complete program?

He said: > Please do not use -w in the hashbang, it forces > warnings everywhere, even when modules didn't want warnings. You'll > get weird error messages if you leave that in. Instead just write "use > warnings;" at the top of your code and you'll be fine. :) > It activates warnings for code you did not write. > > It is an extremely good idea to enable warnings for all code you write > yourself.

Insert data and set foreign keys with Postgres
I have to migrate a large amount of existing data in a Postgres DB after a schema change. In the old schema a country attribute would be stored in the users table. Now the country attribute has been moved into a separate address table: users: country # OLD address_id # NEW addresses: id country When migrating the data, I'm having problems setting the foreign keys in the users table after inserting the addresses: INSERT INTO addresses (country) SELECT country FROM users WHERE address_id IS NULL RETURNING id; **How do I propagate the IDs of the inserted rows and set the foreign key references in the users table?** The only solution I could come up with so far is creating a temporary user_id column in the addresses table and then updating the the address_id: UPDATE users SET address_id = a.id FROM addresses AS a WHERE users.id = a.user_id; However, this turned out to be extremely slow (despite using indices on both users.id and addresses.user_id). **Is there any other way to insert derived data into one table and setting the foreign key reference to the inserted data in the other (without changing the schema itself)?** I'm using Postgres 8.3.14.

Opera browser extension extension-reload via function
I'm developing an extension for Opera Browser and I'm searching for a function that is able to reload an Opera extension or an alternative way to solve my problem. I want the user to be able to switch between an old version of the extension (the list view or 'newmenu') and the new version (the normal view or 'oldmenu'). The code to do this is as follows: <a id="switch" href="javascript: void(0)" onClick="widget.preferences.version = 'newmenu'; document.getElementById('switch').innerHTML = 'Please reload the extension';">[Switch to Normal View]</a> The **widget.preferences.version = 'newmenu'** in this **oldmenu.html** file, sets the user preference to use the new menu and **widget.preferences.version = 'oldmenu'** (not shown here), which is located in the **menu.html**, sets the user preference to use the old menu. Then, in the **index.html** file, the extension checks whether it has to show the old menu or the new menu. if (widget.preferences.version == "oldmenu") { var ToolbarUIItemProperties = {title: "4chan Boards", icon: "icons/icon_64x64.png", popup: {href: "oldmenu.html", width: 220, height: 620}} } else { var ToolbarUIItemProperties = {title: "4chan Boards", icon: "icons/icon_64x64.png", popup: {href: "menu.html", width: 250, height: 350}} } Now, the problem is that for this code to execute, the user has to manually reload the extension, which is very ugly. And well, since the Opera Developing Forum is currently unreachable (bad gateways and long loading times), I guess this is the best place to ask my question. Thanks for your time.

Creating a dynamic tree array from another array
I have an array, lets call it $childrenIds, it outputs as follows: array( [74252] => Array ( [0] => 1753 [1] => 1757 [2] => 1758 [3] => 1760 ) [74238] => Array ( [0] => 1753 [1] => 1755 [2] => 1758 [3] => 1761 ) [76476] => Array ( [0] => 1754 [1] => 1755 [2] => 1758 [3] => 1763 ) [76478] => Array ( [0] => 1754 [1] => 1756 [2] => 1758 [3] => 1763 ) [76480] => Array ( [0] => 1754 [1] => 1757 [2] => 1758 [3] => 1763 ) [74253] => Array ( [0] => 1753 [1] => 1757 [2] => 1759 [3] => 1760 ) ); What i need to do is create a new array from this, where the e.g. [74252] is ignored, but the children of each sub array are pathed... So using this example my output would be something like: array( [1753] => Array ( [1757] => Array ( [1758] => Array ( 1760 ), [1759] => Array ( 1760 ), ) [1755] => Array ( 1758 => Array ( 1761 ) ) ) ), [1754] => Array ( [1755] => Array ( [1758] => Array ( 1763 ) ), [1756] => Array ( [1758] => Array ( 1763 ) ), [1757] => Array ( [1758] => Array ( 1763 ) ) ) ); So there will not always be 4 sub array elements, that is dynamic... Hopefully I have explained this clearly, been searching for a few hours and can't find a solution that meets all of my requires, if I overlooked one, I apologize in advance. Thanks

What is more efficient IList<T> or IEnumerable<T>
What is more efficient way to make methods return IList<'T'> or IEnumerable<'T'> ? IEnumerable<'T'> it is immutable collection but IList<'T'> mutable and contain a lot of useful methods and properties. To cast IList<'T'> to IEnumerable<'T'> it is just reference copy: IList<'T'> l = new List<'T'>(); IEnumerable<'T'> e = l; To cast IEnumerable<'T'> to List<'T'> we need to iterate each element or to call ToList() method: IEnumerable<'T'>.ToList(); or may pass IEnumerable<'T'> to List<'T'> constructor which doing the same iteration somewhere within its constructor. List<'T'> l = new List<'T'>(e); Which cases you think is more efficient? Which you prefer more in your practice?

Access List items in hidden "Forms" folder using Lists.GetListItems
Is it possible to access the list items in the (hidden) "Forms" subfolder of a document library using the `Lists.GetListItems` web service method? I need to set the content type of uploaded document templates using `Lists.UpdateListItems`, otherwise, document created from these templates will have the 'Document' content type and not the content type the template had been assigned to. `Lists.UpdateListItems` works in subfolders of the "Forms"' folder, but I need the `ows_UniqueId` of the list item that represents the uploaded file, and I can only get it using `List.GetListItems`. Is there maybe another method of uploading files to SharePoint document libraries, in which you can set the content type?

Trouble with accessing a member function
I'm using the EasyBMP library. This library has a method: int red = image(i, j)->Red; // Gets the value stored in the red channel at coordinates (i, j) of the BMP named image and stores it into the int named red. Here's the code that I have: `int red = images[i](x, y)->Red;`//images is a dynamic array, I'm using a for loop here images is a member variable of the class with this declaration: Image **images; The error I'm getting is: scene.cpp:195: error: ‘*(((Image**)((const Scene*)this)->Scene::images) + ((Image**)(((long unsigned int)i) * 8ul)))’ cannot be used as a function I understand where its getting mixed up, but I dont know how to fix it. Any ideas?

Partial EMMA code coverage in Scala Case Class for IntelliJ IDEA 10.5
I'm using IntelliJ IDEA 10.5 with the Scala plugin v0.4.1338 updated on August 14th, and Scala 2.9.0.1. I recently began using the EMMA test coverage utility in IDEA to generate coverage reports. I cannot determine why the constructor line of my Scala case class is only showing partial (yellow) coverage. I have looked in the EMMA FAQs and researched the matter online with no success. Does anyone have any idea how I can reach 100% coverage on a case class?

Confuzed about the future of programming
I am a young undergraduate engineering student who needs your help about his future. Let me be clear from the beginning. I love electronics. Analog electronics, especially. But, what I see is that programming has taken over the world. You see programming languages and algorithms everywhere, from sites about jobs to the best magazines in the field (IEEE magazines). It is like we have found a limit in electronics and software is the only way to push this industry forward. I dare you to take a look at a hardware magazine. The closest thing you are going to see about analog electronics is mathematics related to signal processing theory, which assume the existence of the actual devices they are going to use. So here is my dilemma. Should I, also, choose the way of software? The problem is that I don't like writing code, except of assembly, but I like mathematics. Thank you.

Automating Firefox and Chrome browsers
I am looking for a way to automate couple of browsers... Firefox and Chrome (for now on just Windows) from an external application/process. Is there a way to do things along these lines: 1. Start the browser with a URL 2. Have the browser load up the page, run script etc. 3. Inspect the DOM For reference, IE can be automated using the InternetExplorer.Application object which can be created in a shell script using the following javascript, and then I can walk the DOM API: var ie = new ActiveXObject('InternetExplorer.Application'); The motivating scenario here is automated testing. I'd like to load up the page containing the test code, and gather results after the test has run.

How to convert any text/font to its bezier path representation?
I have a bezier path library to draw complex bezier paths without problem. Now, I need to know how to read a text or font and extract its path information to draw it as a path instead of as text. I came across a C applicaiton, [FontForge](http://fontforge.sourceforge.net/). It does exactly what I need, picks any font and extract its path information. But what I need to know is how it does it to add that feature to my drawing library.

Does Objective C implementation is much slower plain C? (optimization)
I'm working on painting application and implementing flood fill. I implemented it using Objective C but without using any Apple's framework. Basically algorithm was ported from plain C. At the moment there are 2 implementations - Floodfill4 anf Scanline floodfill. Both spend around 5secs on iPad to fill 800x600 rectangle. Here is my algorithm: https://github.com/OgreSwamp/ObjFloodFill/blob/master/src/FloodFill.m Do you think it is worth to invest some time to port it to pure C. Will I have sighnificant performance increase? Do you see any other way to increase performance? Thanks!

Menu not working with on page anchors and out of page anchors
Not really sure how to phrase my question but here's my issue: I have a php template type site where the main navigation is in it's own file. Some of the navigation buttons point to anchors on the main page and some go to other pages completely. My original menu used links like index.php#<someid> for the on page anchors and index.php?page=<somepagename> for the off page links. I had two issues with this: 1. When I selected an on page link the page seemed to refresh and it was slow taking me to the place on the page the link was connected to. 2. I'm using htaccess to redirect my url from mydomaincom/index.php to mydomaincom/ and found that my nav didn't work in Safari since my href addresses where index.php#value and Safari v5 wouldn't carry over the anchor links. Rather than turn off my redirect I just changed the urls to point to mydomaincom/#value. Not only did this work great for all browsers but it also made my page quicker. Now however when I'm on one of the other pages say index.php?page=photos and I use the nav it just tries to find the anchors on that page (which makes sense but obviously not what I want). What it's doing now: mydomaincom/index.php?page=photos#<idname> What I need it to do: mydomaincom/#<idname> Since the same nav file is used for all pages do I need to create a nave link variable so that when the nav is on a non-index.php page the link urls that hook to the index.php on page anchors uses the full url? Hopefully this makes sense. Any suggestions? Also trying to keep this search engine/Google friendly :) Thanks!

Initializing with a subclass's ctor
struct A { B b; A(int x):b(x){} A(int x, float g) // how to implement this? I want to init b as a C. }; struct B { enum {e_c, e_d} type; int i; B(int i_):i(i_){} }; struct C : public B { float f; C(int i_, float f_):B(i),f(f_){} }; struct D : public B { double ff; D(int i_, double d):B(i),ff(d){} }; Perhaps there is another way to code this? Originally I just had the class B, but I decided to split it up so I didn't keep adding (incompatible/mutually exclusive) fields to B. My solution was, when A uses b it checks b's enum to see what type it is, then casts a B* to a C* or a D* to get the float or double. My problem is now I don't know how to let A initialize b. Does the language even let me do something like that? **edit**: I just realized A's b couldn't possibly have allocated space to allow for C or D's extra fields. There wouldn't be any available space to store the float or double. So I guess the right way to do what i want is to add into B a `union {float f; double ff;};`?

Should I use R or Octave for modification of tab delimitated text files?
I have a bunch of text files with tab delimited data, like so X Y Z 1 2 Q K 4 2 I want to examine these for certain properties, and then modify them in different ways depending on the result, eventually creating new text files with information added and/or deleted. Now, according to my own investigations, both R and Octave could probably do this. Should I prefer one of them over the other for this task?

How to integrate Meteor and Ext.js?
I´m trying to figure out the most elegant way of bringing Meteor and Ext together. Obviously Ext has it´s own Ext.data.Store and Proxies to handle REST backends. Meteor has a publish/subscribe model with pusing updates automatically. My first thought would be do write a custom "MeteorProxy" and to handle all the update events there. I´m not sure though this is wise in terms of filtering or sorting data. Ideally filtering should take place on the Meteor side because data sorts/filters ideally should persist across to other (non-ext) views of the data. Alternatively there would be e.g. the way of using the MemoryProxy and write some glue code to update it...

Foursquare API for venue user image error
The Foursquare API has divided its photo tag for user as prefix and suffix. But if I merge them to form a full image URL and paste this in my browser, gives me errors that says the image can't be displayed because it contains errors. Is it because server is temporarily unavailable or anything else ? Any clue ? I am using the API for Venue Detail . Thanks in Advanced.

When I put button.grid(sticky=SE), for example, the button is not being put in the bottom-right and is just being put in the upper-left, ignoring the sticky value. What am I doing wrong here?

Auto Refresh document title?
I have tried many ways to have the page title automatically update every 2.5 seconds so the title can display how many unread messages they have. Here is what I have tried: setInterval(function() { document.title = "<?php echo $inboxcc; ?>"; }, 3000); and $(function() { setInterval(function() { $(this).attr("title", "<?php echo $inboxcc; ?>"); }, 3000); }); But none of them work. Any suggestions would be appreciated. Thanks

Auto Refresh document title? === I have tried many ways to have the page title automatically update every 2.5 seconds so the title can display how many unread messages they have. Here is what I have tried: setInterval(function() { document.title = "<?php echo $inboxcc; ?>"; }, 3000); and $(function() { setInterval(function() { $(this).attr("title", "<?php echo $inboxcc; ?>"); }, 3000); }); But none of them work. Any suggestions would be appreciated. Thanks

C++: Strings with whitespace in a list?
I have this function sentanceParse whit a string input which returns a list<string>. The input might be something like "Hello my name is Anton. What's your name?" and then the return value would be a list containing "Hello my name is Anton" and "What's your name?". However, this is not what happens. It seems as if the whitespaces in the sentances are treades like a separator and therefore the return is rather "Hello", "my", "name" etc instead of what I expected. How would you propose I solve this? As I am not a 100% sure the problem does not lie within my code, I will add that to the post as well: Main: list<string> mylist = sentanceParse(textCipher); list<string>::iterator it; for(it = mylist.begin(); it != mylist.end(); it++){ textCipher = *it; cout << textCipher << endl; //This prints out the words separately instead of the entire sentances. sentanceParse: list<string> sentanceParse(string strParse){ list<string> strList; int len = strParse.length(); int pos = 0; int count = 0; for(int i = 0; i < len; i++){ if(strParse.at(i) == '.' || strParse.at(i) == '!' || strParse.at(i) == '?'){ if(i < strParse.length() - 1){ while(i < strParse.length() - 1 && (strParse.at(i+1) == '.' || strParse.at(i+1) == '!' || strParse.at(i+1) == '?')){ if(strParse.at(i+1) == '?'){ strParse.replace(i, 1, "?"); } strParse.erase(i+1, 1); len -= 1; } } char strTemp[2000]; int lenTemp = strParse.copy(strTemp, i - pos + 1, pos); strTemp[lenTemp] = '\0'; std::string strAdd(strTemp); strList.push_back(strAdd); pos = i + 1; count ++; } } if(count == 0){ strList.push_back(strParse); } return strList; }

Waiting for event to be handled
I have one function let's call it Func1 and `it contains` Func2 & event handler. Now what I would like to achieve is `not let` function (Func1) return value till Func2 fires and handles event. Basically Func1 has string as return value and string value is set inside even handler so I need to wait for event to be handled and then return value. Code Example public static string Fun1 () { string stringToReturn = String.Empty; Func2(); //Func2 will after few sec fire event bellow example.MyEvent += (object sender, WebBrowserDocumentCompletedEventArgs e) => { stringToReturn = "example"; //this wont be hardcoded }; //wait for event to be handled and then return value return stringToReturn; }

Getting started with WPF apllications in vb 2010 because winforms has no graphical sense
Hello i have been using vb.net for a little while now and i am annoyed that you can't have true transparent images or even simple fading for a rich interface experience. but luckily there's WPF! but i have no idea on how to use it and even fading an image on that which by an image i mean a button made out of a hover, normal and down .png file state, not coded gradients through XAML, is not that simple!? i only started designing websites with css and html and jQuery about three weeks ago but i can see some similarities in the languages. so if one of you guys could please point me in the right direction that would be great and maybe also you could show me how to create a fading hover button :) with XAML. Thank you

BadKeyError: Invalid string key incorrect padding
I'm using a standard couple of lines of code to retrieve a key from a http get request and use it to get something from the datastore, but am running into a problem that I haven't encountered before. This is only happening on the live (deployed) version - there are no problems when running the code on the dev server. The code snippet: imgId = self.request.args.get("img_id") imageInfo = db.get(imgId) And an error example: BadKeyError: Invalid string key ahFjeWJlcm5hdXRzcHJvamVjdHINCxIFSW1hZ2UY1oYDDA=. Details: Incorrect padding If I log the value of imgId right before the db.get, it is correct (without the appended "=" from the debug message). Does anyone know what might be causing this?
