How to give interactive inputs in a single line for .exe windows <p>I am trying to automate one process which involves giving interactive input to a .exe utility. It expects the user-input for each step. I wanted to give all those values at single time while giving that command only. For eg: <code>./test.exe 8\n1\n0</code> etc. I have tried multiple ways to give input to the 'test.exe' utility like <code>8\n1\n0 | ./test.exe</code> and <code>8,1,2 | ./test.exe</code>. None of these worked. Any help how to pass these options 8,1,2 to the interactive utility test.exe in single line so that it will be helpful for my automation</p>
| <p>There is no set way to automate a 3rd party program with Powershell. Not all utilities even offer the ability to do so.</p>
<ol>
<li><p>I'd look in the utility documentation for any switches.</p></li>
<li><p>Try the following to see if you can get any built in help: test.exe -h, test.exe /h, test.exe /?, test.exe -?</p></li>
<li><p>use the sysinternals strings utility to try and find anything that look like command line switches inside the exe that you can take advantage of.

Entity Framework M:1 relationship resulting in primay key duplication <p>I'm somewhat new to EF 6.0 so I'm pretty sure I'm doing something wrong here.
there are two questions related to the problem</p>
<ol>
<li>what am I doing wrong here</li>
<li>what's the best practice to achieve this</li>
</ol>
<p>I'm using a code first model, and used the edmx designer to design the model and relationships, the system needs to pull information periodically from a webservice and save it to a local database (SQL Lite) in a desktop application</p>
<p><a href="https://i.stack.imgur.com/AicE1.jpg" rel="nofollow"><img src="https://i.stack.imgur.com/AicE1.jpg" alt="enter image description here"></a></p>
<p>so I get an order list from the API, when I populate and try to save Ticket, I get a duplicate key exception when trying to insert TicketSeatType - </p>
<p>how do I insert the ticket to dbContext, so that It doesn't try and re-insert insert TicketSeatType and TicketPriceType, I have tried setting the child object states to unchanged but it seems to be inserting</p>
<p>secondly, what would be the best practice to achieve this using EF ? it just looks very inefficient loading each object into memory and comparing if it exists or not</p>
<p>since I need to update the listing periodically, I have to check against each object in the database if it exists, then update, else insert</p>
<p>code:</p>
<pre><code>//read session from db
if (logger.IsDebugEnabled) logger.Debug("reading session from db");
dbSession = dbContext.SessionSet.Where(x => x.Id == sessionId).FirstOrDefault();
//populate orders

<h1>UPDATE:</h1>
<p>Found the answer, it has to do with how EF tracks references to objects, in the above code, I was creating new entity types from the list for TicketPriceType and TicketSeatType:</p>
<pre><code> foreach (var o in ordersList) {
dbOrder = dbContext.OrderSet.Where(x => x.Id == o.OrderId).FirstOrDefault();
foreach (var t in o.Tickets) {
var ticket = new Ticket {
Id = t.TicketId,
Quantity = t.Quantity,
TicketPrice = t.TicketPrice,
TicketPriceType = new TicketPriceType {
Id = t.TicketPriceType.TicketPriceTypeId,
Description = t.TicketPriceType.Description,
SeatCount = t.TicketPriceType.SeatCount,
},
TicketSeatType = new TicketSeatType {
Id = t.TicketSeatType.TicketSeatTypeId,
Description = t.TicketSeatType.Description
},
Order = dbOrder
};
....
</code></pre>
<p>in this case the EF wouldn't know which objects they were and try to insert them. </p>
<p>the solution is to read the entities from database and allocate those, so it's referencing the same entities and doesn't add new ones</p>
<pre><code>foreach (var t in o.Tickets) {
//check from db
dbTicket = dbContext.TicketSet.Where(x => x.Id == t.TicketId).FirstOrDefault();
dbTicketSeatType = dbContext.TicketSeatTypeSet.Where(x => x.Id == t.TicketSeatType.TicketSeatTypeId).FirstOrDefault();
dbTicketPriceType = dbContext.TicketPriceTypeSet.Where(x => x.Id == t.TicketPriceType.TicketPriceTypeId).FirstOrDefault();
var ticket = new Ticket {
Id = t.TicketId,
Quantity = t.Quantity,
TicketPrice = t.TicketPrice,
TicketPriceType = dbTicketPriceType,
TicketSeatType = dbTicketSeatType,
Order = dbOrder
};
...}
</code></pre>
| <p><strong><em>Don't you think that you are trying to write very similar codes for defining the state of each entity?</em></strong>
We can handle all of these operations with a single command.</p>
<p>You can easily achieve this with the newly released <a href="https://www.nuget.org/packages/EntityGraphOperations/" rel="nofollow">EntityGraphOperations</a> for Entity Framework Code First. I am the author of this product. And I have published it in the <a href="https://github.com/FarhadJabiyev/EntityGraphOperations" rel="nofollow">github</a>, <a href="http://www.codeproject.com/Tips/1131322/Automatically-Define-the-State-of-All-Entities-in" rel="nofollow">code-project</a> (<em>includes a step-by-step demonstration and a sample project is ready for downloading)</em> and <a href="https://www.nuget.org/packages/EntityGraphOperations/" rel="nofollow">nuget</a>. With the help of <code>InsertOrUpdateGraph</code> method, it will automatically set your entities as <code>Added</code> or <code>Modified</code>. And with the help of <code>DeleteMissingEntities</code> method, you can delete those entities which exists in the database, but not in the current collection.</p>
<pre><code>// This will set the state of the main entity and all of it's navigational
// properties as `Added` or `Modified`.
context.InsertOrUpdateGraph(ticket);
</code></pre>
<p>By the way, I feel the need to mention that this wouldn't be the most efficient way of course. The general idea is to get the desired entity from the database and define the state of the entity. It would be as efficient as possible.</p>

Validate end_date is after start_date <p>I have a form with two date fields, <code>start_date</code> and <code>end_date</code>. I want to create a rule that <code>end_date</code> must be greater then <code>start_date</code>, and if this condition returns <code>false</code> then to show validation errors as in the picture below. </p>

var end_date = $("input[name='end_date']").val();
return end_date(value) > start_date(value);
}, 'End date must be greater then start date.');
</code></pre>
<p>I'm not sure how exactly I set the rule and the message.</p>
| <p>Got it.</p>
<pre><code> $.validator.addMethod("check_date", function(value, element) {

var end_date = $("input[name='end_date']").val();
return end_date > start_date;

How to rename master branch and make another branch as master? <p>I have several branches in my repo - master, production, staging, other_stuff
I want to set my production branch as master, and rename my master branch to master_legacy.</p>
<p>How can I do it?
Actually I found guide, but I'm not sure, whether I can implement it here:</p>
<pre><code>git checkout production
git merge -s ours master
git checkout master
git merge production
</code></pre>
| <p>If you really just want to rename the branches and not merge information together; I would go for:</p>
<pre><code>git branch master_legacy master # create a new branch master_legacy where master is
git branch -D master # force deleting the master branch
git branch master production # create a new master branch where production is
</code></pre>
<p>afterwards you might need to do some cleanup such as:</p>
<pre><code>git push -f origin master # force pushing the new master to your remote
</code></pre>

Bitbucket doesn't create visual branch <p>I'm new to git and working with bitbucket.
Did I do something wrong that bitbucket doesn't show a visual branch? It looks like i'm still working in master.
I have other commits before in the master branch.</p>

| <p>You did not do anything wrong. Bitbucket shows your commit history just like it is: a linear list of commits (some of which have branches pointing to them). In git, a branch is merely a pointer to a commit.</p>
<p>As soon as you make divergent commits on the two branches, you will see two visual branches on the graph.</p>

| <p>IIS has a feature called "Recycling". This basically reloads everything in IIS.</p>
<p>If you go into Advanced Settings of your Application Pool in the IIS Manager there is an Recycling Interval which by default is 1740 minutes (29 hours)</p>
<p>When IIS Recycles, your application will not begin running until something calls the webservice. So once every 29 hours it will recycle, so depending on when you started your webservice it will run your Cron job once or twice but never a 3rd time unless you have called your webservice after the recycle to restart it. </p>
<p>Basically, IIS is not a good place to host an application which needs to be always running jobs. </p>

How to generate automatically Makefile in vim (c/c++) super fast? <p>I'm quite new to vim,
have installed few plugins one of them is SnipMate,
which is quite useful while writing a short Makefile.</p>

CFLAGS = -g -Wall
all: $1
%.o: %.c $(CC) $(CFLAGS) -c -o $@ $<

$(CC) $(CFLAGS) -o $@ $+
clean: rm -f *.o core.*
mrproper: clean rm -f $1
</code></pre>
<p>but still it takes time to add manually the file names,
I'm quite sure with some <strong>Vim Magic</strong> :) , Vim would able to do it <strong>automatically</strong> (executing it via hotkey) after I have wrote those c files, any suggestions?</p>
<p>Thank you all!</p>
| <p>You can extract filenames automatically with <code>glob()</code>, and <code>globpath()</code> (don't ask me about SnipMate syntax to import the result -- I'm maintaining another template/snippet plugin). </p>
<p>But if you always use <strong>everything</strong> automatically, why don't you do it directly with make? There are ways to automatically glob filenames that match a pattern. If you need to trim files, well in that case listing explicitly every file you want to keep makes sense. But don't forget to remove unwanted files every time you trigger the <em>update the file list</em> action you wish to define.</p>
<p>BTW, IIRC, a properly configured gnumake (i.e, not mingw one) already has the rule for <code>%.o: %.c</code></p>

Good tutorial - <a href="http://www.vogella.com/tutorials/AndroidLiveWallpaper/article.html" rel="nofollow">http://www.vogella.com/tutorials/AndroidLiveWallpaper/article.html</a></p>
<p>2) Set AlarmManager( tutorial - <a href="https://developer.android.com/training/scheduling/alarms.html" rel="nofollow">https://developer.android.com/training/scheduling/alarms.html</a>) and change pictures every tick.</p>

Finding a "trail" in 2-D dimention arrays <p>I don't know how to figure out this question, I am just a beginner to computer science.</p>
<p>The input will be 2D array A[n][n] numbers, representing the topographic map of the geographic surface. Also among the input will be a starting location (r,c). referring to entry A[r][c]</p>
<p>If you were planning hiking trails you would be bound by the differences in elevation between neighboring entries. A person could traverse between 2 adjacent locations, if their elevations differ by no more than 2). Adjacency follows just the 4 standard compass directions, (so I assume no diagonals). Therefore , a point on the map is considered reachable if it is traversable from A[r][c] through any sequence of adjacent entires.</p>
<p>Write an algorithm that computes all of the reachable locations. The output will be another 2D array R[n][n] with true/fals values. (I assume true means reachable, false means unreachable)</p>
<p>If i understand this question correctly, I can create following matrix. (suppose A[10][10] looks like this from A[0][0]:)</p>
<pre><code>50 51 54 58 60 60 60 63 68 71
48 52 51 59 60 60 63 63 69 70
44 48 52 55 58 61 64 64 66 69
44 46 53 52 57 60 60 61 65 68
42 45 50 54 59 61 63 63 66 70
38 42 46 56 56 63 64 61 64 62
36 40 44 50 58 60 66 65 62 61
36 39 42 49 56 62 67 66 65 60
30 36 40 47 50 64 64 63 62 60
50 50 50 50 50 50 50 50 50 50
</code></pre>
<p>Both south and east are traversable from A[0][0] so reachable entries would be:</p>
<pre><code>50 51 54 58 60 60 60 63 68 71
48 52 51 59 60 60 63 63 69 70
44 48 52 55 58 61 64 64 66 69
44 46 53 52 57 60 60 61 65 68
42 45 50 54 59 61 63 63 66 70
38 42 46 56 56 63 64 61 64 62
36 40 44 50 58 60 66 65 62 61
36 39 42 49 56 62 67 66 65 60
30 36 40 47 50 64 64 63 62 60
50 50 50 50 50 50 50 50 50 50
</code></pre>

</code></pre>
<p>Our professor ask us to implement this in pseudocode. I don't know how to do comparisons for two neighbor points and 4 directions of the point. Anyone can give me some ideas? </p>
| <p>It's just flood fill. You need a queue and an index-addressable vector of "visited" flags. Put the root into the queue. Whist the queue is not empty, take the first element, and check for reachable locations N,S,E,W. Then check if they have been visited. If not, mark them as visited, and put them in the queue. </p>

When window is resized, span element not getting its width <p>Here's the screenshot:
<a href="https://i.stack.imgur.com/uegLZ.png" rel="nofollow"><img src="https://i.stack.imgur.com/uegLZ.png" alt="enter image description here"></a></p>
<p>And here's the code:</p>
<pre><code>.contact_section .contact_form input[type="text"], .contact_section .contact_form input[type="email"]{
border: 1px solid black;
margin: 15px 0;
font-size: 16px;

</code></pre>
<p>The problem is that, at normal window size, it looks perfect as shown in the screenshot. But if resize the window(to less than 510px) and back to the full size window, the <code>email</code> textbox goes to the next line!</p>
<p>Here's the screenshot:</p>
<p><a href="https://i.stack.imgur.com/nWSED.png" rel="nofollow"><img src="https://i.stack.imgur.com/nWSED.png" alt="enter image description here"></a></p>
<p>What I noticed is that, the parent <code><span></code> element now doesn't have a width! I have been trying to figure out why its happening, for many hours now. But still no success! :(</p>
<p>Btw, am using <code>ContactForm7</code> for the contact form.</p>
<hr>
<p><strong>EDIT</strong></p>
<p>SOLVED! I set the <code>span</code> elements to <code>inline-block</code> as well as set the <code>30.2%</code> <code>width</code> to them instead of the textboxes. And some margin adjustments fixed the issue! Thank you</p>
| <p>The CSS property <code>display:inline</code> does not accept widths and heights. Change this to inline-block to solve your issues.</p>
<pre><code>.contact_section .contact_form input[type="text"], .contact_section .contact_form input[type="email"]{
border: 1px solid black;

extra characters after close-brace <p>The same code that works on Linux doesn't work on FreeBSD</p>
<p><strong>On Linux</strong></p>
<pre><code>% set timeZone "-4:0"
-4:0
% set timeZone [format "%+03d%02d" {*}[scan $timeZone "%d:%d"]]
-0400
% puts $tcl_version

-4:0
% set timeZone [format "%+03d%02d" {*}[scan $timeZone "%d:%d"]]
extra characters after close-brace
% puts $tcl_version
8.4
</code></pre>
<p>How to make this work on both FreeBSD and Linux?</p>
| <p>You will have to use <code>eval</code>, since list expansion (<code>{*}</code>) <a href="http://wiki.tcl.tk/17158" rel="nofollow">was implemented in Tcl 8.5</a>. You could perhaps use something like this:</p>
<pre><code>set timeZone "-4:0"
set code "format \"%+03d%02d\" [scan $timeZone "%d:%d"]"
# This gives you "format "%+03d%02d" -4 0"
set timeZone [eval $code]
</code></pre>
<p>If you don't like escaping the quotes, you can use braces (which IMO is a bit cleaner):</p>
<pre><code>set code "format {%+03d%02d} [scan $timeZone {%d:%d}]"
</code></pre>

can I use grant_type=client_credentials for google api? <p>I create a clientid, and clientcredentials in google console. when I request the token with <code>grant_type=client_credentials</code>. I got <code>401 unauthrorized</code>.</p>

"error_description": "Unauthorized",
"error_uri": ""

Deserialize flattened JSON keys to proper objects with GSON <p>We ingest an external API (we cannot change the JSON we receive) which produces JSON with flattened keys. For example:</p>
<pre><code>{
"composite.key": "value",
"normal": "another value",
"composite.key2": "back here again..."
}
</code></pre>
<p>which we would ideally like to deserialize into:</p>
<pre><code>public class SomeObject {
public String normal;
public Composite composite;
}
public class Composite {
public String key;
public String key2;
}
</code></pre>
<p>while we know we can write a custom deserializer, I would first like to check if there is support for this in GSON using annotations or by some other means.</p>
| <p>You can use GSON's <a href="https://google.github.io/gson/apidocs/com/google/gson/annotations/SerializedName.html" rel="nofollow">@SerializedName</a> annotation on the Java fields.</p>

<pre><code>public class Composite {
@SerializedName("composite.key")
public String key;
@SerializedName("composite.key2")
public String key2;
}

<p>All we know how it works in native enviroment, but what would be the best technique to reproduce the same in web? Thanks in advance for any advise.</p>
<p>EDIT: for those who think that question is too broad. I dont need code in answer, I want to get an idea on what whould be the best approach to solve this.</p>
| <p>You'll have to add a Pseudo element at the end of the list(with some height).</p>
<p>Now in Javascript check if the offset of this element is above the bottom of screen and scroll up to hide it (with some delay).</p>
<p>Also hide the scroll bar else it may look a bit weird.</p>

Passing a vector as a reference to a recursive function <p>I've build a function that accepts a reference to a vector as argument, it looks like this :</p>
<pre><code>void func(std::vector<int> &vec) {
// sth. to do
}
</code></pre>
<p>But i want that the function is recursive and calls itself with a part of the original vector.</p>
<pre><code>void func(std::vector<int> &vec) {
// sth. to do
func(part of the orignial vector);
}
</code></pre>
<p>How can i construct a new vector from my original vector ? It's important that when I modify the part of the vector in the recursive call, that the original vector "vec" has also this changes, so i didn't wan't to pass a copy or new vector.
Thanks for your help.</p>
| <p>The old way!</p>
<pre><code>void func(std::vector<int> &vec,int l,int r) {
// this function modifies only vec fro indices l to r.
//
// do what you want
//
//
func(vec,new_l,new_r);
}

install4j obsolete files not removed on upgrade <p>I am writing a sample upgrade installer and added in few files and removed up some files. I see that the added files are getting properly placed but the removed are not getting deleted.</p>
<p>how to handle this</p>
| <p>You can add an "Uninstall previous installation" action to the "Installation" screen of your installer in order to remove those files.</p>

Connection: keep-alive in nginx webserver <p>I have enabled the Connection: keep-alive in my nginx webserver. And its working fine as well. My query is in nginx access logs i am getting the below message many times. I believe its due to the keep-alive but what exactly the server is doing? Thanks in advance.</p>
<p>Access Log Message:
"GET / HTTP/1.0" 302 43 "-" "HTTP-Monitor/1.1" "-"</p>
| <p>If I'm not mistaken, when the keep alive activates the web server sends a packet to the client to indicate that the connection is still active, so those messages are in the log.</p>

Integrating Auth0 authentication with existing user database <p>I've a requirement to integrate Auth0 in our project (Reactjs/Hapijs/MySQL). I checked the documentation and they have many examples and that is great, however, I can't find any related to how exactly do I use my existing user database.</p>
<p>In my application I have users and those users can have one or more projects. With the authorization that we currently use, a user logs in, I check what projects does he own and send it to the React application.</p>
<p>I am missing a document that explains me how to use Auth0 and still be able to check in my database what projects user owns.</p>
<p>My idea on how that should work (I might be wrong):</p>
<ol>
<li>User sends username and password to our server</li>
<li>Our server makes request to Auth0 (with provided credentials)</li>
<li>Auth0 replies back to our server with some <strong>token</strong></li>
<li>We look in users table in our database and try to verify the existence of that user</li>
<li>If it is a match then we simply look (as we already do) for user projects.</li>
</ol>
<p>Is this how it is supposed to work?</p>
| <p>There are a few options available for scenarios where you want to integrate Auth0 with applications that already have existing user databases. You can either:</p>
<ol>
<li>continue to <a href="https://auth0.com/docs/connections/database#using-a-custom-user-store" rel="nofollow">use your existing store</a></li>
<li>progressively <a href="https://auth0.com/docs/connections/database#migrating-to-auth0-from-a-custom-user-store" rel="nofollow">migrate your users from your custom store</a> to the Auth0 store</li>
</ol>
<p>You don't mention it explicitly, but judging from your expected flow it seems you would be wanting to implement the first option. <strong>There is specific documentation that you can follow that explain how you can setup your custom database connection, see <a href="https://auth0.com/docs/connections/database/mysql" rel="nofollow">Authenticate Users with Username and Password using a Custom Database</a></strong>. It mentions MySQL, but others database servers are supported and there are many templates that will allow you to quickly setup things.</p>
<p>When you complete this the final flow will be the following:</p>
<ol>
<li>Using either Auth0 authentication libraries (Lock) or your custom UI you'll ask the user for their credentials</li>
<li>Either Lock or your custom UI submits the credentials to Auth0 authentication API</li>
<li>Auth0 authentication API validates the credentials by calling scripts that execute against your custom database (these scripts were provided by you when you configured the database connection)</li>
<li>If the credentials are valid the Authentication API will return a token to the calling application that will have user information and proves the users is who he say he is.</li>
</ol>
<p>The scripts you need to provide are the following, but only one is mandatory:</p>
<ul>
<li>Login script (executed each time a user attempts to login) (<strong>mandatory</strong>)</li>
<li>Create user script</li>
<li>Verify email script</li>
<li>Change password script</li>
<li>Delete user script</li>
</ul>
<p>The optional scripts are only required when you want to provide the associated functionality through Auth0 libraries, if only need the login to work then you can skip them. The login script, in the case of a valid user, is also where you return the profile information of the user, for example, you could in theory include their owned projects in the user profile.</p>

Deciding when to use a hash table <p>I was soving a competitive programming problem with the following requirements:</p>
<p>I had to maintain a list of unqiue 2d points (x,y), the number of unique points would be less than 500.</p>
<p>My idea was to store them in a hash table (C++ unordered set to be specific) and each time a node turned up i would lookup the table and if the node is not already there i would insert it.</p>
<p>I also know for a fact that <strong>i wouldn't be doing more than 500 lookups</strong>.
So i saw some solutions simply searching through an array (unsorted) and checking if the node was already there before inserting.</p>
<p>My question is is there any reasonable way to guess when should i use a hash table over a manual search over keys without having to benchmark them?</p>

</blockquote>
<p><sup>I am guessing you are familiar with basic algorithmics & <a href="https://en.wikipedia.org/wiki/Time_complexity" rel="nofollow">time complexity</a> and C++ <a href="http://en.cppreference.com/w/cpp/container" rel="nofollow">standard containers</a> and know that with luck hash table access is O(1)</sup></p>
<p>If the hash table code (or some balanced tree code, e.g. using <code>std::map</code> - assuming there is an easy order on keys) is more readable, I would prefer it for that readability reason alone.</p>
<p>Otherwise, you might make some guess taking into account the <a href="http://norvig.com/21-days.html#answers" rel="nofollow">approximate timing for various operations on a PC</a>. BTW, the entire <a href="http:///norvig.com/21-days.html" rel="nofollow">http:///norvig.com/21-days.html</a> page is worth reading.</p>
<p>Basically, memory accesses are much more slow than everything else in the CPU. The <a href="https://en.wikipedia.org/wiki/CPU_cache" rel="nofollow">CPU cache</a> is extremely important. A typical memory access with cache fault requiring fetching data from DRAM modules is <em>several hundreds times slower</em> than some elementary arithmetic operation or machine instruction (e.g. adding two integers in registers).</p>
<p>In practice, it does not matter that much, as long as your data is tiny (e.g. less than a thousand elements), since in that case it is likely to sit in L2 cache.</p>
<p>Searching (linearly) in an array is really fast (since very cache friendly), up to several thousand of (small) elements.</p>
<p>IIRC, <a href="https://herbsutter.com/" rel="nofollow">Herb Sutter</a> mentions in some video that even <em>inserting</em> an element inside a vector is practically -but unintuitively- faster (taking into account the time needed to move slices) than inserting it into some balanced tree (or perhaps some other container, e.g. an hash table), up to a container size of several thousand small elements. This is on typical tablet, desktop or server microprocessor with a multimegabyte cache. YMMV.</p>
<p>If you really care that much, you cannot avoid benchmarking.</p>
<p>Notice that 500 pairs of integers is probably fitting into the L1 cache!</p>

Select Orders of Last Month in MySQL <p>I have to write a query that selects Last month orders from a table Order( id , ......., order_date).</p>
<p>Assume that the date of today is 4th of April. Will i select orders from 1st March to 31th of March or from the 4th of March to the 4th of April ??? </p>
<p>Edit :
The first query : </p>
<pre><code>SELECT * from Order where order_date between sysdate() and sysdate - INTERVAL 1 Month
</code></pre>
<p>The Second Query : </p>
<pre><code> SELECT * from Order where order_date between (Last_day(sysdate()) - INETRVAL 1 MONTH)
and ((Last_day(sysdate()) + INTERVAL 1 DAY) - INETRVAL 2 MONTH))
</code></pre>
<p><code>(Last_day(sysdate()) - INETRVAL 1 MONTH)</code> gives 30 of March</p>
<p><code>((Last_day(sysdate()) + INTERVAL 1 DAY) - INETRVAL 2 MONTH))</code> gives 1st of March</p>
| <p>"Last month" typically means the whole period of the month prior to today. So if today was 4th April then last month is</p>
<pre><code> >= 1st March and < 1st April
</code></pre>
<p>E.g.</p>
<pre><code>Select * from orders
Where order_date >= '2016-03-01'
and order_date < '2016-04-01'
</code></pre>
<p>Note I recommend avoiding between for date ranges. Also note that the time of 23:59:59 is NOT the end of a day and that recent versions of mysql do support subsecond time precision.</p>

| <p>I think the most straightforward approach would be to follow <a href="http://robjhyndman.com/hyndsight/detecting-seasonality/" rel="nofollow">Rob Hyndman's approach</a> (he is the author of many time series packages in R). For your data it would work as follows,</p>
<pre><code>require(fma)
# Create a model with multiplicative errors (see https://www.otexts.org/fpp/7/7).
fit1 <- stlf(test2)
# Create a model with additive errors.
fit2 <- stlf(data, etsmodel = "ANN")
deviance <- 2 * c(logLik(fit1$model) - logLik(fit2$model))
df <- attributes(logLik(fit1$model))$df - attributes(logLik(fit2$model))$df
# P-value
1 - pchisq(deviance, df)
# [1] 1

<p>Based on this analysis we find the <em>p-value</em> of 1 which would lead us to conclude there is no seasonality.</p>

| <p>Usually this kind of data is retrieved from the server via ajax. For example you can provide a Spring MVC Controller that returns your sub tasks as a JSON array and your angular app would need to retrieve that data from your Spring MVC Controller via ajax.</p>

Xamarin Forms trouble with SQLite and await <p>I'm using the sqlite-net-pcl nuget, in my view model I am trying to get the list of announcements from my database </p>
<pre><code> private SQLiteAsyncConnection connection;
public ObservableCollection<Announcement> AnnouncementList { get; private set; }
public AnnouncementsViewModel() {
connection = DependencyService.Get<ISQLiteDb>().GetConnection();
Initialize();
}
public async void Initialize() {
await connection.CreateTableAsync<Announcement>();
var announcements = await connection.Table<Announcement>().ToListAsync();
AnnouncementList = new ObservableCollection<Announcement>(announcements);
System.Diagnostics.Debug.WriteLine("***********************************");
System.Diagnostics.Debug.WriteLine(AnnouncementList.Count);
}
</code></pre>
<p>in my code behind, in the constructor: </p>
<pre><code> BindingContext = new AnnouncementsViewModel();
InitializeComponent();
var list = (BindingContext as AnnouncementsViewModel).AnnouncementList;
</code></pre>
<p>The error I get is:</p>
<blockquote>
<p>System.NullReferenceException: Object reference not set to an instance
of an object.</p>
</blockquote>
<p>I put a break point in my viewModel, when it arrives to the first await it returns to the code behind and the App crashes. I get the null exception because the AnnouncementList is not filled in the viewModel and it didn't print the stars.
How can I solve this problem?</p>
<p>Thanks</p>
| <p>You can't just call your async <code>Initialize()</code> method in a sync way like that. It will return immediately and by the time you get around to using <code>AnnouncementList</code>, <code>Initialize</code> isn't finished running yet and it is still null.</p>
<p>It's not an ideal solution but you should add <code>.Wait()</code> after <code>Initialize()</code> to ensure it completes before you exit the constructor.</p>
<p>I say 'not ideal' because depending on your context <code>Wait()</code> might block. If that happens you're probably better off doing that initialization work before constructing your ViewModel, using only 'proper' awaiting, and passing <code>AnnouncementsList</code> into the constructor.</p>

Entity Framework temporary save <p>We are building a website where users can add/edit/remove students and their related info. Everything works great, but now we want to allow anonymous users to try our demo school.</p>
<p>Demo school is the same as regular school but we want users to be able to edit/delete information on the page without it being persisted in the database (This way this demo is always the same, despite of the user changes)</p>
<p>One way to do this is to run hourly SQL scripts that will clean-up records but this is not ideal because it will require running a scheduler, plus if user is trying out the demo sometimes data will be erased during their visit.</p>
<p>Is there a way to temporarily save data in a session or other storage and then wipe so demo is not affected? </p>
| <p>use a temporary database and as soon as you want to switch to the original one just change the web.config file , if you use Code first it will be easy else you need to generate sql+data from the original database to the temporary . </p>

Can not convert JSON to domain object with spring restTemplate <p>Actually I try to invoke a get request with the restTemplate in Spring. Debbuging my application clearly shows that the JSON is downloaded but the automatic mapping does not work. My List of domain object includes only 0 values and null values.
When I invoke the get request from the browser, I get the following response as JSON (I copied here the first two record out of the 3 192):</p>
<pre><code>[{"OrderId":77862,"DateAdded":"2016-04-30T02:25:40.263","OrderItemCorpusId":"HUBW","OrderItemCorpusOriginalId":null,"OrderItemCurrency":"HUF","OrderItemExchangeRate":1.00000,"OrderItemOriginalLocation":"HU","OrderItemBuyLocation":"HU","OrderItemPrice":1337.80314,"OrderItemDiscountId":0,"OrderItemDiscountValue":"","DocumentId":25140,"Title":"Romana Gold 10. kötet","PublisherOriginalName":"Harlequin Kiadó","ISBN":"9789634073369"},{"OrderId":77864,"DateAdded":"2016-04-30T15:49:22.61","OrderItemCorpusId":"HUBW","OrderItemCorpusOriginalId":null,"OrderItemCurrency":"HUF","OrderItemExchangeRate":1.00000,"OrderItemOriginalLocation":"HU","OrderItemBuyLocation":"HU","OrderItemPrice":2748.03149,"OrderItemDiscountId":0,"OrderItemDiscountValue":"","DocumentId":25252,"Title":"Az eltűnt lány","PublisherOriginalName":"Harlequin Kiadó","ISBN":"9789634072423"}]
</code></pre>
<p>My POJO domain object which should keep the converted data from JSON:</p>
<pre><code>@JsonIgnoreProperties(ignoreUnknown = true)
public class BandWTransaction {
private long OrderId;
private Date DateAdded;
private String OrderItemCurrency;
private double OrderItemExchangeRate;
private String OrderItemBuyLocation;
private double OrderItemPrice;
private String OrderItemDiscountValue;
private long DocumentId;
private String Title;
private String PublisherOriginalName;
private String ISBN;
//getters and setters
</code></pre>
<p>Finally the code snippet I use for the rest get request:</p>
<pre><code>String startDate = new SimpleDateFormat("yyyy-MM-dd").format(start.getTime());
String endDate = new SimpleDateFormat("yyyy-MM-dd").format(end.getTime());
UriComponents uri = UriComponentsBuilder.newInstance().scheme("http").host("www.bookandwalk.hu")
.path("/api/AdminTransactionList").queryParam("password", "XXX")
.queryParam("begindate", startDate).queryParam("enddate", endDate).queryParam("corpusid", "HUBW")
.build().encode();
LOG.log(Level.INFO, "{0} were called as a rest call", uri.toString());
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.set("User-Agent", "Anything");
HttpEntity<String> entity = new HttpEntity<String>(headers);
ResponseEntity<List<BandWTransaction>> transResponse = restTemplate.exchange(uri.toString(), HttpMethod.GET,
entity, new ParameterizedTypeReference<List<BandWTransaction>>() {
});
List<BandWTransaction> transactions = transResponse.getBody();
</code></pre>
<p>When I debug the app I realized that the transactions list includes objects with full of null and 0 values. More precisely, there is no and objcet within the list having other values as 0 and null in the properties.
I have also checked that spring boot automatically registered in the restTemplate.messageConverters ArrayList 9 HttpMessageConverter. The 7th element of this ArrayList is the org.springframework.http.converter.json.MappingJackson2HttpMessageConverter which supports the application/json and application/+json media types.
Any idea is appreciated to solve this problem as I am newbie in spring and in JSON mapping in general.</p>
| <p>I can suggest you to write a test and check how fasterxml ObjectMapper read a json and unmarshall json to your object:</p>
<pre><code>ObjectMapper objectMapper = new ObjectMapper();
String somestring = objectMapper.readValue("somestring", String.class);
</code></pre>
<p>just replace <em>String</em> with your class and <em>"somestring"</em> with your json. So you check if there is problem with it. </p>
<p>And try to use @JsonPropery cause all this capital letters fields start with looks messy:</p>
<pre><code>@JsonIgnoreProperties(ignoreUnknown = true)
public class BandWTransaction {
@JsonProperty("OrderId")
private long OrderId;
[...]
</code></pre>
<p>With this stuff I read json correct. You can come in from other side remove ignoring unknown properties:</p>
<p>@JsonIgnoreProperties(ignoreUnknown = true) //remove it and run test
public class BandWTransaction {</p>
<p>and you get :</p>
<blockquote>
<p>(11 known properties: "dateAdded", "orderItemExchangeRate",
"documentId", "orderItemPrice", "orderId", "orderItemBuyLocation",
"orderItemDiscountValue", "orderItemCurrency", "isbn", "title",
"publisherOriginalName"])</p>
</blockquote>
<p>So problem in variables naming and you can fix it with @JsonProperty</p>

How do I convert multiple elements of a character array into an integer? <p>Say I have,</p>
<pre><code>char x[0] = '1';
char x[1] = '2';
</code></pre>
<p>I need to 'concatenate' these two into an integer variable,</p>
<pre><code>int y = 12;
</code></pre>
<p>How do I do this?</p>
| <p>As long as you terminate <code>x</code> with a NULL-terminator you can use <code>atoi</code>.</p>
<p><a href="http://ideone.com/z22XKk" rel="nofollow">Example</a>:</p>
<pre><code>#include <stdlib.h>
#include <stdio.h>
int main() {
char x[3];
x[0] = '1';
x[1] = '2';
x[2] = '\0';
int x_int = atoi(x);
printf("%i", x_int);
return 0;
}

Deploying Angula2 UI application in High Availability Mode <p>Currently we have implemented a Angular2 UI application and deployed in single server. We would like to implement the UI application in high availability mode by deploying the UI application in 2 servers(1 in active mode and another one in stand-by mode). Is there any easy way of implementing it in Angular2 and nodeJS?</p>
<p>Thanks,
Rajkumar</p>
| <p>Angular2 runs in the client (browser) only. </p>
<p>The server only serves static HTML, JS, and CSS files. There are no specific requirements for an Angular2 server (except when you want to use server side rendering). Just build your Angular2 source and you will only get static files for deployment.</p>
<p>Any HTTP server will do and any HTTP server can serve multiple clients (it's main purpose ;-) )</p>

Plot decision boundaries of classifier, ValueError: X has 2 features per sample; expecting 908430" <p>Based on the scikit-learn document <a href="http://scikit-learn.org/stable/auto_examples/svm/plot_iris.html#sphx-glr-auto-examples-svm-plot-iris-py" rel="nofollow">http://scikit-learn.org/stable/auto_examples/svm/plot_iris.html#sphx-glr-auto-examples-svm-plot-iris-py</a>.

| <p>The thing is you <strong>cannot</strong> plot decision boundary for a classifier for data which is not <strong>2 dimensional</strong>. Your data is clearly high dimensional, it has 908430 dimensions (NLP task I assume). There is no way to plot actual decision boundary for such a model. Example that you are using is trained on <strong>2D data</strong> (reduced Iris) and this is <strong>the only reason</strong> why they were able to plot it.</p>

auto load php script <p>I have shared folder between in my server which will allow other server to send XML file to me and I want my script read this file auto without opening any page.
I know how to open and read the file.</p>
<p>But the issue how to auto load in the backhand. </p>
| <p>you have to create a one page which will read the provided file and do the required actions , then share this URL and format with the team who will going to provide you the xml file.</p>
<p>It is very much like API Endpoint, Where you have to write the code which will handled request and in this scenario your Endpoint will treat as a server and XML file provider will treat as clients.</p>
<p>I hope this answer helps u.

Looping through array to store duplicate string and add up values of the same string C++ <p>Relatively new to C++ , the following is my code:</p>

{
date[i] = stockpile[i].datepurchased; // stockpile.datepurchased give the date,already seperated by :

dailyprice += stockpile[i].unitprice; // trying to add the total price of the same dates and print the
// datepurchased(datepurchased should be the same) of the total price
// means the total price purchased for 9oct16
}
}
cout<<endl;
}
</code></pre>
<p>everything is already retrieved and and seperated by : from the methods i have wrote</p>
<p><code>stockpile[i].unitprice</code> will print out the price</p>
<p><code>stockpile[i].itemdesc</code> will print out the item description</p>
<p>PROBLEM</p>
<p>I am trying to sum up unitprice of the same dates. and display the total unitprice + date
as u can see my textfile , </p>
<p>if i do the above if statement of <code>date[i] == date[j]</code> but it won't work because what if there is another 9oct somewhere else?</p>
<p>My textfile is:</p>

<p><strong><em>//EDIT//</em></strong> after trying Ayak973's answer , compiled with g++ -std=c++11 Main.cpp</p>

| <p>With c++11 support, you can use std::unordered_map to store key/values pair: </p>
<pre><code>#include <string>
#include <unordered_map>
std::unordered_map<std::string, int> totalMap;
//...
for(i=0;std::getline(myfile,myline);i++) {
auto mapIterator = totalMap.find(stockpile[i].datepurchased); //find if we have a key
if (mapIterator == totalMap.end()) { //element not found in map, add it with date as key, unitPrice as value
totalMap.insert(std::make_pair(stockpile[i].datepurchased, stockpile[i].unitprice));
}
else { //element found in map, just sum up values
mapIterator->second += stockpile[i].unitprice;
}
}
</code></pre>
<p>After that, you got one map with date as keys, and sum of unit price as values. To get the values, you can use range based for loop :</p>
<pre><code>for (auto& iterator : totalMap) {
std::cout << "Key: " << iterator.first << " Value: " << iterator.second;

Ruby Morse Decoder <p>I tried to create a Morse Decoder. It replaces latin letters with their morse codes. There is one whitespace between letters and three whitespace between words.</p>

<p>What is wrong?</p>
| <p>The problem is here:</p>
<pre><code>word.gsub! letter a
</code></pre>
<p>it is being interpreted from the right to the left since there is no comma between <code>letter</code> and <code>a</code> itâs being treated as <code>letter(a)</code> function call. You want both <code>letter</code> and <code>a</code> to be passed as parameters to a function call â separate them <em>with comma</em>:</p>
<pre><code># â HERE
word.gsub! letter, a

<p>BTW, <code>gsub</code> might take a hash as a second param to make substitutions:</p>
<pre><code>word.gsub(/./, morse_dict)
</code></pre>
<p>would change all letters to their Morse representations. To deal with spaces one might use <code>gsub</code> that takes a block:</p>
<pre><code>word.gsub(/./) { |l| " #{morse_dict[l]} " }.squeeze(' ')

<p>Plus, you can directly access the select value:</p>
<pre><code>$.ajax({
method: "POST",
url: "action.php",
dataType: "json",
data: {
city: $('#city').val()
},
})
</code></pre>
<p>At the level of PHP, you have to decode the value of <code>$_POST['city']</code> to get a mapped PHP array:</p>
<pre><code>$city = json_decode($_POST['city']);

Mailchimp API form not sending final welcome email <p>I'm trying to build a custom form in my site using the <code>Mailchimp API</code>. I've managed to write up a <code>PHP</code> script which is adding my users to a mailing list from within the Mailchimp dashboard. However I'm having an issue sending them an auto responder email.</p>
<p>This is my <code>HTML</code> form:</p>
<pre><code><form method='post' action='<?= get_template_directory_uri() ?>/mailchimp.php'>
<input type='text' name='email'/>
<input type='submit' name='submit' value='Subscribe'/>
</form>
</code></pre>
<p>This is my code that handles the request to Mailchimp and adds a user to a list:</p>
<pre><code>session_start();
if(isset($_POST['submit'])){
$email = $_POST['email'];
if(!empty($email) && !filter_var($email, FILTER_VALIDATE_EMAIL) === false){
// MailChimp API credentials
$apiKey = 'xxx';
$listID = 'xxx';
// MailChimp API URL
$memberID = md5(strtolower($email));
$dataCenter = substr($apiKey,strpos($apiKey,'-')+1);
$url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listID . '/members/' . $memberID;
// member information
$json = json_encode([
'email_address' => $email,
'status' => 'subscribed'
]);
// send a HTTP POST request with curl
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
$result = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
echo "<h1>$httpCode</h1>";
return $httpCode;
}
}
</code></pre>
<p>I read that you cannot send a final welcome email to anyone unless they are marked as <code>subscribed</code> to your list. I understand Mailchimp enforces a double optin policy unless overriden using the API by setting the users status to subscribed as I've done below:</p>
<pre><code>// member information
$json = json_encode([
'email_address' => $email,
'status' => 'subscribed'
]);
</code></pre>
<p>but for some reason I am still not receiving an email upon subscribing to the list. Would anyone have any suggestions as to what I am doing wrong.</p>
<p>I've ensured from backend of Mailchimp that the Final Welcome Email is setup.</p>
| <p>I've managed to resolve my issue and I'm posting this answer here for anyone who may experience a similar problem to me regarding the sending of a welcome email by way of the single opt-in process.</p>
<p><strong>Double Opt In Process</strong></p>
<p>Mailchimp enforces a double opt-in policy whereby a user who signs up for your newsletter/service will be sent 2 emails. The first is a confirmation email which enables the user to confirm they requested to join your list. The second is a welcome email - only sent once the user is added to your list.</p>
<p><strong>Overriding the Double Opt in Process</strong></p>
<p>You can override this functionality by using the <code>Mailchimp API</code>. You must ensure that you add the user with the status of <code>subscribed</code> so that they do not have to go through the double opt-in process. However, this still will not mean that the welcome email is sent. </p>
<p><strong>Sending the Welcome Email</strong></p>
<p>In order to send this welcome email you must set up an Automation rule. This rule should contain a trigger which is fired immediately after a user subscribes to a list. You can set these rules up in the Mailchimp backend. By doing this you can then send welcome emails to subscribers via the single opt in process. </p>
<p><strong>Automation Rules</strong></p>
<p>Bear in mind that the Automation rule will only trigger once per email. So if someone were to unsubscribe or be deleted from the list and resubscribed with the same email no welcome email would be received. </p>
<p><strong>For Wordpress</strong></p>
<p>If you are using <code>Wordpress</code> a great <code>plugin</code> which handles the integration to Mailchimp is <code>Mailchimp for Wordpress</code>. However this on it's own won't work - you need to add the automation via your mailchimp account to send the welcome emails.</p>
<p>I hope this helps people in the future!</p>

DB2Driver from jar dependency not found <p>I have created a small jar distribution that sets up a database connection for me.
Problem is that when i add it as a gradle dependency I get:</p>
<pre><code>java.lang.ClassNotFoundException: com.ibm.db2.jcc.DB2Driver
</code></pre>
<p>Gradle dependecie tree:</p>
<pre><code>--- prokasdb-connector:prokasDBConnection:2.0

+--- prokasdb-connector-dependencies:db2jcc_license_cu:0.1
\--- prokasdb-connector-dependencies:db2small:0.1
</code></pre>
<p>Another remark is that when I go to the build path via eclipse menu i noticed that the last for dependencies are missing, while the rest where added automatically. The db2 connector is contained within the last 4 jars, that is why java cannot find it</p>
| <p>Add this to your <code>build.gradle</code> and run <code>gradle findClass</code> from command line</p>
<pre><code>task findClass {
doLast {
def foundJars = [] as Set
configurations.runtime.files.each { jar ->
zipTree(jar).visit { FileVisitDetails fvd ->
def path = fvd.relativePath.pathString.replace('\\', '/')
if (path == 'com/ibm/db2/jcc/DB2Driver.class') {
foundJars << jar
}
}
}
println "Found driver in ${foundJars}"

Eloquent relationships: cloumn doesn't exist <p>I'm new to Laravel and am having a bit of a hard time cracking how relationships work. I'm building a simple e-commerce application, where each user has some orders, and order has one or many sub-orders, and each sub-order is linked to only one item (please don't comment on my scheme yet; for now I just need to figure out Eloquent and will be doing refactoring later :) ).</p>
<p>Following are my models:</p>
<pre><code>class Order extends Model
{
//timestamp
protected $created_at;
public function sub_orders() {
return $this->hasMany('App\SubOrder');
}
public function user() {
return $this->belongsTo('App\User');
}
}
class SubOrder extends Model
{
protected $fillable = array('delivery_date', 'quantity', 'total_price', 'delivery_status');
public function item() {
return $this->hasOne('App\Item');
}
public function order() {
return $this->belongsTo('App\Order');
}
}
class Item extends Model
{
//note - slug is kind of categorization and is common to many items
protected $fillable = array('sku', 'name', 'slug', 'unit_price');
}
</code></pre>
<p>And here are the migrations:</p>
<pre><code>class CreateOrdersTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('orders', function (Blueprint $table) {
$table->increments('id');
$table->timestamp('created_at');
//foreign keys
$table->unsignedInteger('user_id')->after('id');
$table->foreign('user_id')->references('id')->on('users') ->onDelete('cascade');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('orders');
}
}
class CreateSubOrdersTable extends Migration
{
public function up()
{
Schema::create('sub_orders', function (Blueprint $table) {
$table->increments('id');
$table->date('delivery_date');
$table->decimal('quantity', 5, 2);
$table->decimal('total_price', 7, 2);
$table->enum('delivery_status', ['pending_from_farmer', 'ready_for_customer', 'out_for_delivery', 'delivered']);
//foreign keys
$table->unsignedInteger('order_id')->after('id');
$table->foreign('order_id')->references('id')->on('orders') ->onDelete('cascade');
$table->unsignedInteger('item_id')->after('order_id');
$table->foreign('item_id')->references('id')->on('items') ->onDelete('cascade');
});
}
public function down()
{
Schema::dropIfExists('sub_orders');
}
}
class CreateItemsTable extends Migration
{
public function up()
{
Schema::create('items', function (Blueprint $table) {
$table->increments('id');
$table->string('sku')->unique();
$table->string('name');
$table->string('slug');
$table->decimal('unit_price', 5, 2);
});
}
public function down()
{
Schema::dropIfExists('items');
}
}
</code></pre>
<p>The problematic expression is why I write <code>App\Order::all()[0]->sub_orders[0]->item</code> in my <code>web.php</code> and get the following error:</p>
<pre><code>SQLSTATE[42703]: Undefined column: 7 ERROR: column items.sub_order_id does not exist
LINE 1: select * from "items" where "items"."sub_order_id" = $1 and ...
^ (SQL: select * from "items" where "items"."sub_order_id" = 1 and "items"."sub_order_id" is not null limit 1)
</code></pre>
<p>I don't understand why it's looking for <code>sub_order_id</code> in the <code>items</code> table. And what's the right way to go about doing it?</p>
| <p>Overall: define the 1-to-1 relationship using <code>hasOne</code> or <code>belongsTo</code> will affect the target table where Laravel find the foreign key. <code>hasOne</code> assume there is a <code>my_model_id</code> in target table.And <code>belongsTo</code> assume there is a <code>target_model_id</code> in my table.</p>
<pre><code>class SubOrder extends Model
{
public function item() {
return $this->hasOne('App\Item', 'id', 'item_id');
}
}
</code></pre>
<p>or </p>
<pre><code>class SubOrder extends Model
{
public function item() {
return $this-> belongsTo('App\Item');
}
}
</code></pre>
<p>According to <a href="https://laravel.com/docs/5.3/eloquent-relationships#one-to-one" rel="nofollow">Laravel Doc</a></p>
<pre><code>class User extends Model
{
/**
* Get the phone record associated with the user.
*/
public function phone()
{
return $this->hasOne('App\Phone');
}
}
</code></pre>
<blockquote>
<p>Eloquent determines the foreign key of the relationship based on the model name. In the above case, <strong>the Phone model</strong> is automatically assumed to have a <strong>user_id foreign key</strong>. If you wish to override this convention, you may pass a second argument to the hasOne method:</p>
</blockquote>
<pre><code>$this->hasOne('App\Phone', 'foreign_key', 'local_key');
</code></pre>
<p>Or Defining The Inverse Of The Relationship</p>
<pre><code>class Phone extends Model
{
/**
* Get the user that owns the phone.
*/
public function user()
{
return $this->belongsTo('App\User');
}
}
</code></pre>
<blockquote>
<p>In the example above, Eloquent will try to match the <strong>user_id from the Phone</strong> model to an <strong>id on the User</strong> model.</p>

OData don't connect with SAP Web IDE (local installation) <p>I used automatical OData connection with SAP Web IDE. Unfortunately, Data don't connect and Layout Editor says that Data Set "not defined". I have tried to connect by coding, for example <code><Table items={/Stats}></code>, but it doesn't work either. When I use project template (Master-Detail or Worklist), there are no problems with connection and Data is automatically connecting, but when I want to make my project and make a connection, there are always some problems. </p>

Why the output of this C program that uses fork and shared memory like that? <p>I have question from old exam, Given a C code and m is global variable, when the program finish what the value of m,the answer is "between 7 and 19" but i don't understand why, can someone explain it to me why the answer is between 7-19 and not exactly 19.</p>
<pre><code>int m = 0;
int main() {
int i;
fork();
m=3;
fork();
for(i=0;i<4;i++)
m++;
}
</code></pre>
| <p>The first thing to notice, analysing this problem is that there are no blocking calls, this means that when the main process reaches the end of main the program will finish, regardless of what state the other processes are in.</p>
<p>Using this fact we can work out the lower limit of <code>m</code>: this will be when the forked processes don't change the value of <code>m</code> before the main process exits. In this case m will start at 3, and be added to 4 times in the loop, giving you the lower limit of <code>m = 7</code>.</p>
<p>The upper limit will happen when all processes have been spawned before any enters the loop and then each process will add 4 to <code>m</code> (which will have a starting value of 3). In other words, <code>m = 3 + N*4</code> where <code>N</code> is the total number of processes spawned.</p>
<p>So to finally get the upper limit we need to know how many processes are spawned. The first call of <code>fork()</code> will turn one process into two, and the subsequent call of <code>fork()</code> will turn each of these processes into two, meaning that <code>N = 4</code>.</p>
<p>Using our expression for <code>m</code> from before then we see that the upper limit is <code>m = 3 + 4 * 4 = 19</code></p>

Animation with GSAP <p>I am doing an envelope animation using GSAP, been facing quite a lot of issue but couldn't find much help online.</p>
<p>I am trying to make some animations to 1) rotate from the front of the envelope to back of the envelope, 2) opening of flap and 3) a letter coming out from an envelope.</p>
<p>Currently I am on step 3 now and struggling with "looks like z-index" issue but I am not sure whether is it because of z-index. Somehow I could not get the letter to overlay on top of the flap opening.</p>
<p>Below are my gsap code :</p>
<pre><code>var tl = new TimelineMax();
var $container = $(".container"),
$envelope = $(".envelope"),
$envFront = $(".front"),
$envBack = $(".back"),
$topFlap = $(".top"),
$card = $(".card");
tl.set($container, {perspective:1100})
.set($envelope, {transformStyle:"preserve-3d"})
.set($envBack, {rotationY:-180})
.set([$envBack, $envFront], {backfaceVisibility:"hidden"})
.set([$envBack, $envFront, $card], {scale: 0.6})
.set($topFlap, {transformOrigin: "center top"});
$container.click(function(){
tl.to($envelope, 1, {rotationY: 180})
.to($topFlap, 1, {rotationX: 180, z: 0})
.to($card, 1, {top: -50, opacity: 1}, 1);

Incorrect URLs in Sitecore Habitat <p>After a number of trials, I finally managed to setup Habitat for Sitecore 8.2 </p>
<p>The instance name used is <code>habitatdev</code>. I followed the git document on configuring these custom names in 3 config files in the VS solution. </p>
<p>The home page <a href="http://habitatdev" rel="nofollow">http://habitatdev</a> works fine. But when trying to browse to any other page (say "About"), it goes to <a href="http://habitat.habitatdev/about" rel="nofollow">http://habitat.habitatdev/about</a>. </p>
<p>This is with all other pages. I see there are redirection modules and solutions to create a new layout for redirections.</p>
<p>Is there any simple fix like a property in web.config where we can set the Items to navigate to <a href="http://habitatdev/[name]" rel="nofollow">http://habitatdev/[name]</a> instead of <a href="http://habitat.habitatdev/[name]" rel="nofollow">http://habitat.habitatdev/[name]</a></p>
<p><strong>FIX:</strong><br>
Open this config - <code>\Website\App_Config\Include\Project\Habitat.Website.config</code></p>
<p>Look for the <code>site</code> and <code>cacheSizes</code> properties. </p>
<p><strong>Original:</strong></p>
<pre><code><sites>
<site name="habitatdev" patch:after="site[@name='modules_website']"
targetHostName="habitat.$(rootHostName)" database="web" virtualFolder="/" .... />
</sites>
<cacheSizes>
<sites>
<habitat>
<html>50MB</html>
<registry>0</registry>
<viewState>0</viewState>
<xsl>25MB</xsl>
</habitat>
</sites>
</cacheSizes>
</code></pre>
<p><strong>Changed to:</strong></p>
<pre><code><sites>
<site name="habitatdev" patch:after="site[@name='modules_website']"
targetHostName="$(rootHostName)" database="web" virtualFolder="/" .... />

<cacheSizes>
<sites>
<habitatdev>
<html>50MB</html>
<registry>0</registry>
<viewState>0</viewState>
<xsl>25MB</xsl>
</habitatdev>
</sites>
</cacheSizes>
</code></pre>
| <p>The problem (looking at your comment) is in your site config.</p>
<p>You have:</p>
<pre class="lang-xml prettyprint-override"><code><site name="habitat" targetHostName="habitat.habitatdev" database="web" virtualFolder="/" physicalFolder="/" rootPath="/sitecore/content/habitat" startItem="/Home" ... />
</code></pre>
<p>which means that when Sitecore generates url, it creates them using <code>targetHostName="habitat.habitatdev"</code> for their host names.</p>
<p>Just change it to </p>
<pre class="lang-xml prettyprint-override"><code><site name="habitat" targetHostName="habitatdev" database="web" virtualFolder="/" physicalFolder="/" rootPath="/sitecore/content/habitat" startItem="/Home" ... />
</code></pre>
<p>and all the urls will be <code>http://habitatdev/...</code></p>

| <p><strong>Permission Issue</strong>. It probably has to do with the path names in windows.</p>
<p>Check the same in Git Bash or Windows Powershell. </p>
<p>You can set the NODE path like : <code>set NODE_PATH=source</code></p>
<p>Remove the node_modules and run <code>npm install</code> again.</p>

PDO rollback and beginTransaction , cannot work more than 1 query <p>The first query will execute successfully, but for the second query, it doesn't work.
The following is the coding which I declare my database and executes two of the queries:</p>
<pre><code>$db = new PDO( "sqlsrv:server=$servername ; Database=$databasename", $UserId, $pwd);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->beginTransaction();
$sql2 = "INSERT INTO Header "
. "(Number,Date)"
. "VALUES (:Number, :Date)";
try
{
$stmt2 = $db->prepare($sql2);
$stmt2->bindParam("Number", $Number);
$stmt2->bindParam("Date", $Date);
$stmt2->execute();
$sql3 = "UPDATE table2
SET Number= :Number
WHERE Date= :Date ";
try
{
$stmt3 = $db->prepare($sql3);
$stmt3->bindParam("Number", $Number);
$stmt3->bindParam("Date ", $Date );
$stmt3->execute();
}
catch(PDOException $e)
{
$db->rollBack();
}
$db->commit();
}
catch(PDOException $e)
{
$db->rollBack();
}
</code></pre>
<p>I try before set the autocommit to false by <code>$db->setAttribute(PDO::ATTR_AUTOCOMMIT,0);</code> , however, it show the <code>the auto-commit mode cannot be changed for this driver</code> error message.</p>
| <p>You don't need the inner try...catch clause because either 1st or 2nd error would trigger the rollback anyway.
<strong>Back to your question</strong>, MySQL might not execute your update statement because your target rows aren't identified by unique id . (unsafe update)</p>
<p>you can override the safe update checkpoint as:</p>
<pre><code>SET SQL_SAFE_UPDATES =0;
do the update..
SET SQL_SAFE_UPDATES =1;
</code></pre>
<p>or use unique identifiers in your where clause.</p>

react-native calender picker in dialog in ios <p>In <code>react-native-ios</code>, I am using <code>react-native-datepicker</code> for selecting date from calender.
For this, I am using following link:
<a href="https://github.com/xgfe/react-native-datepicker" rel="nofollow">Date Picker in react-native-ios</a></p>
<p>I am adding following code in my render method:</p>
<pre><code><View style={styles.buttonContainer}>
<TouchableOpacity
style={[styles.bubble, styles.button]}
onPress={() => this.openCalender()}>
<DatePicker
style={{width: 150}}
date={this.state.date}
mode="date"
placeholder="Date"
format="YYYY-MM-DD"
minDate="2015-01-01"
maxDate="2025-12-01"
confirmBtnText="Confirm"
cancelBtnText="Cancel"
iconSource={require('./assets/cal.png')}
onDateChange={(date) => {this.setState({date: date});}}
/>
</TouchableOpacity>
</View>
</code></pre>
<p>but I want to add this date picker in dialog. What will be the way for implementing that in <code>react-native-ios</code>.</p>
<p>I want to put Date picker on NavBar Right button click.</p>
| <p>I am using this library : <a href="https://github.com/xgfe/react-native-datepicker" rel="nofollow">https://github.com/xgfe/react-native-datepicker</a></p>

C++ std::regex How to fix the error_complexity? <p>I used <code>std::regex</code> to match a string. </p>
<p>My define of regex is : </p>
<pre><code>regex reg("(-?\\d+,?){2,}", regex::icase)
</code></pre>
<p>Test string is : </p>
<pre><code>5,3240,7290,11340,-3240,-7290,-11340
</code></pre>
<p>I used std function of <code>regex_match()</code>.
The following is the error I got.</p>
<blockquote>
<p>regex_error(error_complexity): The complexity of an attempted match
against a regular expression exceeded a pre-set level.</p>
</blockquote>
<p>How can I fix the problem ? My compiler is VS2013.</p>
| <p>You may "unroll" the <code>,?</code>-containing group into a more linear pattern to reduce complexity - <code>",?-?\\d+(?:,-?\\d+)+"</code>.</p>
<p>See <a href="https://ideone.com/vGh1Vf" rel="nofollow">C++ demo</a>:</p>
<pre><code>#include <iostream>
#include <regex>
using namespace std;
int main() {
regex reg(",?-?\\d+(?:,-?\\d+)+");
string s("5,3240,7290,11340,-3240,-7290,-11340");
if (regex_match(s, reg)) {
std::cout << "Matched!";
}
return 0;
}
</code></pre>
<p>Now, the pattern matches:</p>
<ul>
<li><code>,?</code> - an optional comma</li>
<li><code>-?</code> - an optional hyphen</li>
<li><code>\\d+</code> - 1 or more digits</li>
<li><code>(?:,-?\\d+)+</code> - 1 or more sequences matching
<ul>
<li><code>,</code> - a comma</li>
<li><code>-?\\d+</code> - see above.</li>
</ul></li>
</ul>

Migrating jquery code from stateless react component to es6 component <p>I have a component that renders a Boostrap modal. I want to add a class to another button when the modal appears, so I have the below code:</p>
<pre><code>const AddContact = () => {
}
$('#myModal').on('show.bs.modal', function (e) {
$('.add-button').addClass("orange-btn")
})
return (
//modal
...
}
</code></pre>
<p>How do I do the same thing with a es6 component? I tried to put the jquery code into the constructor but it didn't work.</p>
| <p>I guess you closed the function's bracket early in 2nd line. Try with this.</p>
<pre><code>const AddContact = () => {
$('#myModal').on('show.bs.modal', function (e) {
$('.add-button').addClass("orange-btn")
})
return (
//modal
...
}

How do I dynamically create a common proxy class of two unrelated classes? <p>I have two unrelated java classes (only <code>*.class</code>, no <code>*.java</code>) like this:</p>
<pre><code>public class Trick {
public String getName() { return "Jack"; }
public String trick() { ... }
}
</code></pre>
<p>and</p>
<pre><code>public class Treat {
public String getName() { return "John"; }
public String treat() { ... }
}
</code></pre>
<p>and I would like to generate a sort of <em>Proxy</em> class at runtime that represents the union of both classes and forwards them to the respective instance, and maybe throw if that's not possible. I assume that can be done with <code>cglib</code> but I don't know where to start.</p>
<p>This is what I would like to do (pseudocode):</p>
<pre><code>// prepare: generate a common interface
TrickOrTreat trickOrTreat = magic.createUnionInterface(Trick.class, Treat.class);
// use with concrete interface A:
Trick trick = new Trick();
TrickOrTreat proxyA = magic.createProxy(trickOrTreat.class, trick);
System.out.println("trick name: " + proxyA.getName());
// use with concrete interface B:
Treat treat = new Treat();
TrickOrTreat proxyB = magic.createProxy(trickOrTreat.class, treat);
System.out.println("treat name: " + proxyB.getName());
</code></pre>
<p>Or something to that effect. I would like to do it completely dynamically, probably <code>cglib</code>-based? If thats not possible I would do it with a code generation step in between?</p>

Serializing a JSON object for a Django URL <p>I have a JSON object that looks like this:</p>
<pre><code>var obj = {
"selection":[
{
"author":"John Doe",
"articles":[
"Article One",
"Article Two"
]
}
]
}
</code></pre>
<p>I want to pass this object to Django to render a view that displays 'Article One' and 'Article Two' upon render. I first serialize the JSON object so that it can be appended to a URL; I use <code>$.param(obj)</code> for serialization. Now the JSON object looks something like this:</p>
<pre><code>"selection%5B0%5D%5Bauthor%5D=John+Doe&selection%5B0%5D%5Barticles%5D%5B%5D=Article+One&selection%5B0%5D%5Barticles%5D%5B%5D=Article+Two"
</code></pre>
<p>Now I can append this to a path and use <code>window.open(url)</code> the view will handle everything else. On the Django end, I was surprised to see that the structure of the JSON object has changed to this:</p>
<pre><code>"selection[0][author]=John+Doe&selection[0][articles][]=Article+One&selection[0][articles][]=Article+Two"
</code></pre>
<p>I want to be able to use the JSON object as a dict e.g.:</p>
<pre><code>obj = request.GET.get('selection')
obj = json.loads(obj)
print(obj[0].author)
...
</code></pre>
<p>How should I handle this JSON structure on the Django side of things?</p>
| <p>You are not properly serializing the object to JSON, even if you say you do. The correct way would be to use <code>JSON.stringify()</code>, as @dunder states.</p>
<p>Than you parse it back to an object with <code>JSON.parse(strignifiedJson)</code>.</p>
<pre><code>var obj = {
"selection":[
{
"author":"John Doe",
"articles":[
"Article One",
"Article Two"
]
}
]
}
// Stringify and encode
var objAsParam = encodeURIComponent(JSON.stringify(obj));
// Send as a param, for example like http://example.com?obj=YourStringifiedObject...
// Parse it back:
var parsedObj = JSON.parse(decodeURIComponent(objAsParam));

ClickOnce Fails to Launch After Install <p>Iâm having a problem with my ClickOnce application at work. The application refuses to launch when its icon is clicked. No error is displayed, it just doesnât load. This is only happening on some deployment machines, not all. As far as I know, all of the machines at work are more-or-less identical ... but I know that often doesn't matter.</p>
<p>The application installs/updates okay -- or appears to. The installation log says everything has installed fine; itâs just when the user tries to launch the application that the problem occurs.</p>
<p>The application DOES launch when I browse to the .exe in the install location (i.e. C:\Users\Username\AppData\Local\Apps\2.0\etc\etc\etc\Application.exe) using the command prompt. </p>
<p>Some details about the non-compliant deployment machines: </p>
<ul>
<li>The machines have the correct .NET prerequisites installed.</li>
<li>They all have the same permissions/firewall settings.</li>
<li>They are all running (or are trying to run, rather!) the most recent version of the application.</li>
<li>I have tried reinstalling the application/deleting the 2.0 folder & updating several times.</li>
<li>There is no Kensington Mouseworks software installed on any of them.</li>
</ul>
<p>Thanks for your advice.</p>
| <p>So, I fixed it ... But not sure how/why this was a fix. Despite the fact that we've disabled UAC on all machines (via the control panel) because we don't want it, I had to make sure that the EnableLUA regkey was set to 1. The thing is, some of the affected PCs already <em>had</em> EnableLUA set to 1, so I simply set it to 0, restarted, set it to 1, then restarted again. (Reg path: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System)</p>
<p>Is UAC ever really turned off? And is there a way to turn it off AND have my application run happily at the same time, on all machines?</p>

how to save change from split content of text <p>I've managed to cut the string a sentence into a word. but the new results can be viewed in the browser when the program runs. but these results can not change the condition of the strings in the original text file. I want the contents of the original text file identical to compile the results in the browser. Well how ya how to store the results of the pieces of the word to the text file? in this case stored in notepad with a .txt extension.</p>
<p>To cut the text I use the following php code:</p>
<pre><code>$width = strlen($openfile)/28000;
$wrapped = wordwrap($openfile, $width,'<br>');
//echo $wrapped;
$stringedit=str_replace(" ", "<br>", $openfile);
echo $stringedit;
</code></pre>
<p>result from browser is like this</p>
<p><a href="https://i.stack.imgur.com/I8dSP.png" rel="nofollow"><img src="https://i.stack.imgur.com/I8dSP.png" alt="enter image description here"></a></p>
| <p>You can use:</p>
<pre><code>file_put_contents ( $fileName); //here filename indicates the name/path of source file.

Therefore, this event is only fired once and only once, throughout the entirety of the web page's lifetime. <code>componentDidMount</code>, on the other hand, is called when a React component is rendered. Therefore, it is entirely possible for <code>componentDidMount</code> to be called several times, albeit for entirely different instances of the same component's class.</p>
<p>And yes, the browser's DOM is always in the "ready state", at the time when a <code>componentDidMount</code> event is called.</p>

json array for events array in jQuery fullcalendar <p>i'm using jQuery fullcalendar and i must set events dynamically, from a query, using a JSON array, for now i'm trying with a static array.
This is my code:</p>
<pre><code><?php

Publishing to npmjs - using a machine user? <p>We're currently working on an open source project (wicked.haufe.io, an API Management system), and for this system, we would like to publish an SDK to npmjs.com for situations where you would want to extend the functionality of the system (it's designed for that).</p>
<p>Now, obviously I don't want to publish to npmjs.com using my own user, but would want to use an organization in some way. My questions regarding this (and I didn't find anything appropriate in the npm documentation on this) are:</p>
<ul>
<li>Can and should I use a machine user for npmjs.com when publishing? Is this allowed? We'd build and publish from our own build pipelines, and those only use machine credentials, not personal ones.</li>
<li>Do I need a paid plan even if my organization only wants to publish open source packages?</li>
</ul>
<p>The second bullet point is not that big an issue, we can do with the minimal $14 for an organization; the first issue is what's interesting.</p>
<p>Best regards, Martin</p>
| <p>From my understanding machine credentials have nothing to do with it. The only credentials that matter are when you try to "npm publish", it will ask for npmjs.com credentials which you have already created (and can be anything). As far as company and publishing information for the package, you can arbitrarily include whatever you want in the package.json file. Just type "npm init".</p>
<p><a href="https://docs.npmjs.com/files/package.json" rel="nofollow">See link here</a></p>
<p>I don't think a paid account would be required.</p>

MySQL find ids for which there is no existing row <p>I have three tables : </p>
<pre><code>1. Person (person_id, name) : (1, "Test1"), (2, "Test2"), (3, "Test3")
2. Role (role_id, description) : (1, "Admin"), (2, "Designer"), (3, "Developer") ..
3. PersonRoles (person_id, role_id) : (1 , 1), (1, 2), (2, 3), (2, 1), (3, 1)
</code></pre>
<p>Is it possible in MySQL with a query to get the ids of the people for which there`s no row with exact role in the PersonRoles table. For Example if I want to check for "Designer" role the query should return ids: 2 and 3</p>
| <p>Here is your solution: </p>
<pre><code>select person_id from Person
where person_id not in
(select person_id from Role r
inner join PersonRoles pr on pr.role_id=r.role_id
where r.description='Designer')

modify lists removing elements without making a mess <p>I'm trying to resolve now a task that sounds like that:</p>
<blockquote>
<p>''write a function modi(la, lb) that takes in input 2 lists la and lb that have the same number of elements inside. The function should <strong>modify</strong> lists la and lb camparing elements with the same indexes in two lists and deleting a bigger one, if elements are equal function delete both of them. ''</p>
</blockquote>
<p>For example:</p>
<ul>
<li>la = ['bear', 'tiger', 'wolf', 'whale', 'elephant'] </li>
<li>lb = ['swan', 'cat', 'dog', 'duck', 'rabbit']</li>
</ul>
<p>So the functin should return:
['bear','elephant']
['cat','dog','duck']</p>
<p>I have wrote the next code but it doesn't modify lists but create new ones and add there elements. Some ideas how can i do that?</p>
<pre><code>def confront(s1, s2):
if s1 < s2: # condition that tells which element to choose later
return 0
elif s2 < s1:
return 1
else:
return 2
def modi(la,lb):
latemp = []
lbtemp = []
i = 0
while i < len(la):
q = confront(la[i], lb[i])
if q == 0:
latemp.append(la[i])
elif q == 1:
lbtemp.append(lb[i])
i +=1
la = latemp
lb = lbtemp
return la, lb
</code></pre>
<p>I have tried remove() but it have created a big mess</p>
| <p>You should use <code>del</code> to delete list item. Also you should iterate from end to the beginning because if you will go from the beginning and delete let say <code>1st</code> element the element that was on the <code>3rd</code> place will be now on the <code>2nd</code></p>
<p>It should look like</p>
<pre><code>#you need to handle what if len of lists is 0, if lens are not the same and so on...
def compare_and_delete(list1, list2):
i = len(list1) -1
while i >= 0:
if list1[i] > list2[i]:
del list1[i]
elif list2[i] > list1[i]:
del list2[i]
else:
del list1[i]
del list2[i]
i-=1
return list1, list2
l1, l2 = compare_and_delete(['bear', 'tiger', 'wolf', 'whale', 'elephant'], ['swan', 'cat', 'dog', 'duck', 'rabbit'])

Login via enter button <p>I have login form and it works fine, but I don't know how to make it work via enter buttom. I did try to make it with JS, but it didn't work for some reason.</p>
<p>Also I think I made horrible code for login :(, but it works.</p>
<pre><code><div class="clientLogin">
<form>
<div class="closeBtn"><i class="icofont icofont-close"></i></div>

</div>
</form>
</div>
</code></pre>
<p>Website: <a href="https://www.xeovo.com" rel="nofollow">https://www.xeovo.com</a></p>
| <p>Make the sign in input a type of <code>submit</code>. Like this,</p>
<pre><code><input type="submit" class="zzzz" onclick="auth()" value="sign in"/>
</code></pre>
<p>This should fix the issue. It's a type of <code>button</code> currently which doesn't get triggered on submitting enter key. </p>

How to get result in blocks immediately? <p>I'm using blocks to get header fields from response in one class and I have to get that in another class. </p>
<p>I implemented code like this</p>
<p>In first class:</p>
<pre><code>- (void)viewDidLoad {
[super viewDidLoad];
UserAuthentication *auth = [[UserAuthentication alloc]init];
NSDictionary *dict = [auth getUserConfiguration];
NSLog(@"%@",dict);
}
</code></pre>
<p>In userAuthentication class:</p>
<pre><code>-(NSDictionary *)getUserConfiguration;
{
__block NSDictionary *resultDictionary;
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:@"http://72.52.65.142:8083/auth"]
completionHandler:^(NSData *data,
NSURLResponse *response,
NSError *error) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
if ([response respondsToSelector:@selector(allHeaderFields)]) {
resultDictionary = [httpResponse allHeaderFields];
NSLog(@"%@",resultDictionary);
}
}] resume];
NSLog(@"%@",resultDictionary);
return resultDictionary;
}
</code></pre>
<p>Here my problem is in first class I'm getting <code>dict</code> as null.</p>
<p>Even in <code>userAuthentication</code> class also I'm getting null.</p>
<p>But after some time call back method is calling and then I can see the response correctly in <code>completionHandler</code>.</p>
<p>So how I can get response in firstClass?</p>
| <p>You are misunderstanding the basic principle of async operation that runs in background thread and when the operation is completed it gives you data in completion block.</p>
<p>To get response in viewDidLoad Method of second class you need to use blocks. like below</p>
<pre><code>-(void)getUserConfigurationOnCompletion:(void (^)(NSDictionary *))completion
{
__block NSDictionary *resultDictionary;
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:@"http://72.52.65.142:8083/auth"]
completionHandler:^(NSData *data,
NSURLResponse *response,
NSError *error) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
if ([response respondsToSelector:@selector(allHeaderFields)]) {
resultDictionary = [httpResponse allHeaderFields];
// Call completion with parameter
completion(resultDictionary);
}
}] resume];
}
</code></pre>
<p>and use it like this in viewDidLoad</p>
<pre><code>- (void)viewDidLoad {
[super viewDidLoad];
UserAuthentication *auth = [[UserAuthentication alloc]init];
[auth getUserConfigurationOnCompletion:^(NSDictionary *dict){
// do necessary work with response dictionary here
NSLog(@"%@",dict);
}];
}

Custom GL plugin's GL Impact Line disappearing when the transaction posting flag is "YES" <p>I have created the <strong>custom GL Plugin and configured to the Invoice Transaction.</strong>
Every created <strong>Invoice Transaction is goes for approval process</strong>, once the invoice is approved the <strong>status changed from pending approval to open status.</strong></p>
<p>when the Invoice Transaction created the Custom GL Impact, working perfectly by creating the Custom GL Lines. Since the Invoice is "Pending Approval State" the Standard and Custom GL Showing correctly and the posting flag is "NO". when the Invoice is approved ,while seeing the GL Impact of the transaction only standard GL Lines are appearing and the Custom GL Lines are disappeared. and posting flag changed to "YES".</p>
<p>My Question is whether the Custom GL Impact plugin will create the custom GL Lines only when the <strong>posting flag is "NO"</strong> or it will remain as it is on the transaction when <strong>posting flag status is both "yes" and "No".</strong></p>
| <p>NetSuite Custom GL Impact will run on on both Non posting and Posting.</p>
<p>Can you provide the code you are using in the Custom GL plugin? It sounds like a logic issue. Do you have any logs?</p>

Last digit in a exponent b <p>I wrote this code to find last digit of a exponent b but SPOJ says its wrong. I tried almost all test cases but couldn't find the error.
Problem:<a href="http://www.spoj.com/problems/LASTDIG/" rel="nofollow">http://www.spoj.com/problems/LASTDIG/</a>
My Solution:</p>
<pre class="lang-java prettyprint-override"><code>package spoj;
import java.util.Scanner;
public class LastDigit {
public static void main(String[] args) throws java.lang.Exception {
Scanner p = new Scanner(System.in);
for(int test = p.nextInt();test>0;test-- ){
int a = p.nextInt();
int b = p.nextInt();
int result = (int) Math.pow(a,b);
System.out.println(result%10);
}
}
}
</code></pre>
| <p><code>Math.pow</code>is a floating point operation! It doesn't compute the exact result. That's why you have that funny cast to int in there.</p>
<p>Therefore you need to use <code>BigInteger</code> or write your own exponentiation function. The latter is the more desirable since the way more efficient way to compute the last digit is to reduce a modulo 10, b modulo 4, <em>then</em> take the power and then reduce modulo 10 again. This should even work within the range were floating-point arithmetic is exact.</p>
<p>Also: You really should have a check in there whether <code>a % 10</code>is even invertible modulo 10 if <code>b</code>is negative. Otherwise your doing the modulo-10-equivalent of a division by zero.</p>

Restoring NSTableView sort order after reload <p>In Interface Builder, an NSTableView is set up with sortable columns (by clicking on the column headers). The data source uses an NSArray. When updating a row of data, the table's data is reloaded which refreshes the array and lays out the data rows according to the array's order.</p>
<p>I would like to keep the table column's sort order. I tried saving the table's sortDescriptors, reloading data, and restoring the table's sortDescriptors, but that does not trigger the desired reload. I suspect I want to refresh the array according to the sortDescriptors such that reloading will lay out as desired. Please enlighten me.</p>
| <p>The answer was under my nose. I can use the data source method <code>tableView:sortDescriptorsDidChange:</code>.</p>
<p>I think a cleaner solution is to post the notification for the data source. It should be the same notification as when clicking on a column header. If anyone knows, kindly share here.</p>

| <p>the issue was in the condition on date that's why I get null in query, so I added the conditions <code>'and day(</code>date<code>) < day(NEW.</code>date<code>) and month(</code>date<code>) <= month(NEW.</code>date<code>) and year(</code>date<code>) <= year(NEW.</code>date<code>)'</code> then I got the right record.</p>

How to create an isolated html page without any link/reference to the home page using angularjs? <p>Am new to AngualrJS. I reference index.html as my home page and I want to map a partial link which is not at all related to the home page(<code>index.html</code>); example,
<code>http://www.example.com/newpage</code>.</p>
<p>Here, the newpage shouldn't have any connection with the <code>index.html</code>. and where to put my <code>newpage.html</code> in the project.</p>
| <p>To achieve what you want, you need to have two differente apps. Every app needs a fixed route prior to the '#'.</p>
<p>So, in your case, index.html would have it's app, and newpage.html would have another one.</p>

Clicking on an element targeted by id but result is still incorrect <p>I am testing Selenium-Webdriver on Google Translate page. What I'm trying to do is:</p>
<ol>
<li>See if the input language is already presented</li>
<li>If presented, is it selected? If not select it.</li>
<li>If not present, open the more language table. Select (click on) the language on the table.</li>
<li>See if the output language is already presented</li>
<li>If presented, is it selected? If not select it.</li>
<li>If not present, open the more language table. Select (click on) the language on the table.</li>
<li>Finally translate and check result</li>
</ol>
<p>I don't have any problem with Case 1: Input and Output language already presented and the result is as expected. But with Case 2: Output language is not presented yet and has to be selected on the table, the problem occurs. <strong>The language selected is incorrect</strong> (for example, I choose Norwegian but finally Samoan will be selected). <em>The select input uses the same way to select but doesn't return any issue at all</em>.</p>

| <p>I would do something like this. You should focus on creating functions that do a single thing so that you have reusable code that can be used in various tests easily.</p>
<p>Here are my functions</p>
<pre><code>static public String getTranslatedText()
{
new WebDriverWait(driver, 10).until(new ExpectedCondition<Boolean>()
{
public Boolean apply(WebDriver d)
{
return d.findElement(By.id("result_box")).getText().length() != 0;
}
});
return driver.findElement(By.id("result_box")).getText();
}
static public void setSourceLanguage(String lang)
{
// see if the desired language is already selected
if (!driver.findElement(By.cssSelector("#gt-lang-src div.jfk-button-checked")).getText().equals(lang))
{
// open the Source language dropdown
driver.findElement(By.id("gt-sl-gms")).click();
// select the desired language
driver.findElement(By.xpath("//div[@id='gt-sl-gms-menu']//div[text()='" + lang + "']")).click();
}
}
static public void setTargetLanguage(String lang)
{
// see if the desired language is already selected
if (!driver.findElement(By.cssSelector("#gt-lang-tgt div.jfk-button-checked")).getText().equals(lang))
{
// open the Source language dropdown
driver.findElement(By.id("gt-tl-gms")).click();
// select the desired language
driver.findElement(By.xpath("//div[@id='gt-tl-gms-menu']//div[text()='" + lang + "']")).click();
}
}
static public void translateText(String text)
{
driver.findElement(By.id("source")).sendKeys(text);
}
</code></pre>
<p>A simple test would look like</p>
<pre><code>driver.get("https://translate.google.com/");
setSourceLanguage("English");
setTargetLanguage("Lao");
translateText("This is some text");
System.out.println(getTranslatedText());
</code></pre>
<hr>
<p>After going through this exercise, I noticed the URL after the text was translated was <a href="https://translate.google.com/#en/lo/This%20is%20some%20text" rel="nofollow">https://translate.google.com/#en/lo/This%20is%20some%20text</a>. I'm assuming that you aren't testing google translate but instead just want the translations? If that's true, you could just navigate to the URL based on the language tokens and pass in the desired text.</p>
<p>The URL is of the form</p>
<pre><code>https://translate.google.com/#<source language token>/<target language token>/<text to be translated>
</code></pre>
<p>So Vietnamese to English would be</p>
<pre><code>https://translate.google.com/#vi/en/This%20is%20some%20text
</code></pre>
<p>and Vietnamese to Norwegian would be</p>
<pre><code>https://translate.google.com/#vi/no/This%20is%20some%20text
</code></pre>
<p>Then all you would have to do is to grab the translated text.</p>

Custom attributes for angular translate <p>I am doing a research if I can use a non alphabetic characters for custom translate value attributes. I walked through that doc</p>
<p><a href="https://angular-translate.github.io/docs/#/guide/06_variable-replacement" rel="nofollow">https://angular-translate.github.io/docs/#/guide/06_variable-replacement</a></p>
<p>and I was playing around here:</p>
<p><a href="http://plnkr.co/edit/MFxE13ioZfzH74TcarM7?p=streamer" rel="nofollow">http://plnkr.co/edit/MFxE13ioZfzH74TcarM7?p=streamer</a></p>
<pre><code>var translations = {
VARIABLE_REPLACEMENT: '{{aa}}_REQUIRES_AN_APPROVAL',
VARIABLE_REPLACEMENT2: '{{@@}}_REQUIRES_AN_APPROVAL'
};
</code></pre>
<p>and I cant display 2nd line of translations as long as I use some symbols in angular expression e.g. {{@@}}</p>
<p>Does anybody know what symbols are allowed for custom attributes of angular translate? Or way to workaround this so that symbols are allowed?</p>
<p>I could not find any doc on that, but I am new to programming so maybe I was searching wrongly:)</p>
| <p>According to <a href="http://stackoverflow.com/a/9337047/744534">this</a> answer, <code>@@</code> can't be an identifier.</p>
<p>Hence <code>@@</code> can't be part of translation texts.</p>

Number guessing what the user has in mind C <p>I'm trying to create a program where the program guesses what kind of number the user has in mind. First it will ask the user for a minimum and maximum number, for example 1 and 10(the number I have in mind should be between 1 and 10 then).<br>
Lets say I have the number 4 in mind and the program will output a number. I can type in L for low, H for high or G for good.<br>
If I type in L, the program should generate a number lower than the guessed number, for H it should guess an higher number. If I input G, the program should stop and print out how many times it guessed.<br>
I have added my code below, what am I missing?</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
int main() {
int minNumber;
int maxNumber;
int counter;
printf("Give min and max: ");
scanf("%d %d", &minNumber, &maxNumber);
//printf("%d %d", minNumber, maxNumber);
int num_between_x_and_y = (rand() % (maxNumber - minNumber)) + minNumber;
char input[100];
do {
printf("is it %d? ", num_between_x_and_y);
scanf("%s", input);
if (input == 'L') {
counter++;
}
if (input == 'H') {
counter++;
}
} while (input != 'G');
printf("I guessed it in %d times!", counter);
return 0;
}
</code></pre>
| <p>You can't use <code>==</code> to compare strings (which are multiple bytes).</p>
<p>Either do <code>if (input[0] == 'L')</code> to just compare the first letter the user entered to a literal value, or <code>if (strcmp(input,"L") == 0)</code> to compare everything the user entered to the 1 character string literal (to use <code>strcmp</code> you will need to add <code>#include <string.h></code></p>
<p>Also your code is missing other things, like counter should be set to presumably set to zero before you use it. I assume you haven't finished your code yet because you can't get the user input part to work.</p>

counting number of true/talse periods in r <p>I have a boolean vector derived from a time series. It basically looks like this: c(true, false, true, true, false, false, false, true, true...).</p>
<p>I want to count the periods in which the vector is true. Example: for a vector like this: c(true, true, false, true) it would be 2 (1 long true period in the beginning, 1 short in the end). </p>
<p>the vector can contain NAs in the beginning. </p>
<p>I thought of something like:</p>
<pre><code>aaa <- c(NA,F,T,T,T,F)
for(j in 1:(length(aaa)-1)){
if(aaa[j]!=aaa[j+1]){
# add a counter that returns [1]
}
}
</code></pre>
<p>=================================================</p>
<p>edit: This works fine for me:</p>
<pre><code>data.frame("#"=unlist(rle(aaa)[1]),"length"=unlist(rle(aaa)[2]))
</code></pre>
| <p>How about this:</p>
<pre><code>aaa[is.na(aaa)] <- FALSE
sum(rle(aaa)$values)
</code></pre>
<p>Convert <code>NA</code>s to <code>FALSE</code>, and the see how many <code>TRUE</code> values there are in the run length encoding (<code>TRUE</code> is stored as 1, <code>FALSE</code> as zero).</p>

Java printf statement giving errors <p>I'm using Eclipse on an a homework assignment and I'm really struggling.

How to prevent JS code from being parsed/evaluated by compiler? <p>I have a module with a lot of JS code in it. Module is created like so:</p>
<pre><code>(function (root, factory) {
// root === window
root.MyModuleName = factory();
})(this, function () {
'use strict';
var MyModuleName = function() {
// A lot of code here that I don't want to be parsed or evaluated
// until MyModuleName constructor is executed.
//
// For example:
// var a = { d: 123 };
// var b = function() { return 45; };
// this.someMethod = function() { b() + a.d };
// ...
};
return MyModuleName;
});
</code></pre>
<p>All methods & properties are inside <code>MyModuleName</code> closure and (I thought) they should be parsed only after <code>MyModuleName()</code> is executed.</p>
<p>After user clicks on some button I create an instance of <code>MyModuleName</code> and execute some method:</p>
<pre><code>someButton.onclick = function() {
// I want compiler to parse and evaluate JS code only here
var myModule = new MyModuleName();
console.log(myModule.someMethod());
};
</code></pre>
<p>Even though <code>MyModuleName</code> constructor is executed() only after click, code inside it is evaluated when JS file loads (I can see it in Chrome dev tools timeline).</p>
<p>How to make sure compiler evaluates code only after click, not after JS file loads?</p>
| <p>You can't. The JS engine has to evaluate the code to create the function before it can assign the function anywhere.</p>
