Searching and capturing a character using regular expressions Python <p>While going through one of the problems in <a href="http://www.pythonchallenge.com/" rel="nofollow">Python Challenge</a>, I am trying to solve it as follows:</p> <p>Read the input in a text file with characters as follows:</p> <pre><code>DQheAbsaMLjTmAOKmNsLziVMenFxQdATQIjItwtyCHyeMwQTNxbbLXWZnGmDqHhXnLHfEyvzxMhSXzd BEBaxeaPgQPttvqRvxHPEOUtIsttPDeeuGFgmDkKQcEYjuSuiGROGfYpzkQgvcCDBKrcYwHFlvPzDMEk MyuPxvGtgSvWgrybKOnbEGhqHUXHhnyjFwSfTfaiWtAOMBZEScsOSumwPssjCPlLbLsPIGffDLpZzMKz jarrjufhgxdrzywWosrblPRasvRUpZLaUbtDHGZQtvZOvHeVSTBHpitDllUljVvWrwvhpnVzeWVYhMPs kMVcdeHzFZxTWocGvaKhhcnozRSbWsIEhpeNfJaRjLwWCvKfTLhuVsJczIYFPCyrOJxOPkXhVuCqCUgE luwLBCmqPwDvUPuBRrJZhfEXHXSBvljqJVVfEGRUWRSHPeKUJCpMpIsrV....... </code></pre> <p>What I need is to go through this text file and pick all lower case letters that are enclosed by only three upper-case letters on each side.</p> <p>The python script that I wrote to do the above is as follows:</p> <pre><code>import re pattern = re.compile("[a-z][A-Z]{3}([a-z])[A-Z]{3}[a-z]") f = open('/Users/Dev/Sometext.txt','r') for line in f: result = pattern.search(line) if result: print result.groups() f.close() </code></pre> <p>The above given script, instead of returning the capture(list of lower case characters), returns all the text blocks that meets the regular expression criteria, like</p> <pre><code>aXCSdFGHj vCDFeTYHa nHJUiKJHo ......... ......... </code></pre> <p>Can somebody tell me what exactly I am doing wrong here? And instead of looping through the entire file, is there an alternate way to run the regular expression search on the entire file?</p> <p>Thanks</p>

<p>Yes, of course there is :-) object oriented techniques are a tool ... if you use the wrong tool for a given job, you will be over complicating things (think spoon when all you need is a knife).</p> <p>To me, I judge "how much" by the size and scope of the project. If it is a small project, sometimes it does add too much complexity. If the project is large, you will still be taking on this complexity, but it will pay for itself in ease of maintainability, extensibility, etc.</p>

<p>Try waiting for window's <code>load</code> event, it waits until all iframes have loaded.</p> <pre><code>$(window).load(function(){ // images and iframes have loaded }) </code></pre>

<p>Assuming that's VB.Net, you need to escape the <code>)</code>:</p> <pre><code>If Regex.IsMatch(Output, "\b" &amp; "Serial\)" &amp; "\b") Then 'do something End If </code></pre> <p>In .Net regular expressions, parentheses are the grouping characters.</p> <hr> <p>If, as you say, the word 'Serial)' is generated dynamically, you will have to <a href="http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex.escape.aspx" rel="nofollow noreferrer">escape</a> it before passing it to the RE engine:</p> <pre><code>If Regex.IsMatch(Output, "\b" &amp; Regex.Escape("Serial)") &amp; "\b") Then 'do something End If </code></pre> <hr> <p>As one other answerer has posted, this won't match <code>"Serial) xyz"</code> (for example) since there's no <code>\b</code> between the <code>)</code> and space (<code>\b</code> only exists <em>between</em> <code>\w</code> and <code>\W</code> characters and both <code>)</code> and a space are <code>\W</code>).</p> <p>You may have to resort to an ugly hack like:</p> <pre><code>If Regex.IsMatch(Output, "\s" &amp; Regex.Escape("Serial)") &amp; "\s") _ Or Regex.IsMatch(Output, "\s" &amp; Regex.Escape("Serial)") &amp; "$") _ Or Regex.IsMatch(Output, "^" &amp; Regex.Escape("Serial)") &amp; "\s") _ Or Regex.IsMatch(Output, "^" &amp; Regex.Escape("Serial)") &amp; "$") _ Then 'do something End If </code></pre> <p>I thought that maybe you could match a character class consisting of (<code>^</code> or <code>$</code>) and <code>\s</code> along the lines of:</p> <pre><code>If Regex.IsMatch(Output, "[\s^]" &amp; Regex.Escape("Serial)") &amp; "[\s$]") Then 'do something End If </code></pre> <p>but this doesn't appear to work based on the regex tester <a href="http://regexlib.com/RETester.aspx" rel="nofollow noreferrer">here</a> so you may have to go for the ugly hack version or you could combine them into a single regex as in:</p> <pre><code>var input = "Serial)" var escaped = Regex.Escape (input) var regex = "\s" &amp; escaped &amp; "\s|^" &amp; escaped &amp; "$|\s" &amp; escaped &amp; "$|^" &amp; escaped &amp; "\s" If Regex.IsMatch(Output, regex) Then 'do something End If </code></pre>

<p>Usually when the add-to-cart button does not display it is because your product has no inventory set. Remember that the configurable product needs to be set to in stock and the associated simple products have to have at least one item with non-zero inventory and be set as 'in stock'.</p>

NSView subclass over another NSView subclass? <p>I'm trying to create an Cocoa-AppleScript Application with some basic functions, and I want to display a background image for the window and then display a color box above it. </p> <p>I finally figured out how to set the background image via this guide (<a href="http://www.mere-mortal-software.com/blog/details.php?d=2007-01-08" rel="nofollow noreferrer">http://www.mere-mortal-software.com/blog/details.php?d=2007-01-08</a>), but I don't know how to set a color box above it. The basic layout I'm trying to achieve is this:</p> <p><img src="https://i.stack.imgur.com/o25EI.png" alt="enter image description here"></p> <p>The window view has a class of <code>ViewBackground</code> which is a subclass of <code>NSView</code>. The <code>ViewBackground.m</code> file looks like this:</p> <pre><code>-(void)drawRect:(NSRect)rect { NSImage *anImage = [NSImage imageNamed:@"repeat"]; [[NSColor colorWithPatternImage:anImage] set]; NSRectFill([self bounds]); } </code></pre> <p>Like I said, that works fine. The problem is when I try to put the box with the background color white above it. I thought I would be able to do this by making a new subclass of <code>NSView</code>, <code>ContentBackground</code>. The <code>ContentBackground.m</code> file looks like this:</p> <pre><code>-(void)drawRect:(NSRect)rect { [[NSColor whiteColor] set]; NSRectFill(rect); } </code></pre> <p>The hierarchy of my windows looks like this:</p> <p><img src="https://i.stack.imgur.com/PzF0I.png" alt="enter image description here"></p> <p>Now this <em>sometimes</em> works, but usually produces this result in the debugger:</p> <pre><code>int main(int argc, char *argv[]) { [[NSBundle mainBundle] loadAppleScriptObjectiveCScripts]; return NSApplicationMain(argc, (const char **)argv); Thread 1: Stopped at breakpoint 1 } </code></pre> <p>What am I doing wrong and how can I fix this?</p> <p>Also, the content (buttons, etc..) will go on top of the <code>ContentBackground</code> box.</p>

<p>Reading your comments, i see that it is not a ZF2 error, and probably not even a third party module, so it could be an ElFinder Error. Probably it cannot find some required resources.</p> <p>Reading some code and some webdites, i think that probably you are just lacking the url option of the viewhelper, so ElFinder can find the backend route he tries to connect to. </p> <p>With the QuElFinder, the route to the connector is <code>/quelfinder/connector</code> so in your view, the code will be:</p> <pre><code>echo $this-&gt;QuElFinder('elfinder', array( 'width' =&gt; "50%", 'height' =&gt; '300', 'url' =&gt; '/quelfinder/connector' ) ); </code></pre> <p>Also, you should go to <code>QuElFinder/config/module.config.php</code> and check everything under </p> <pre><code> 'QuConfig'=&gt;array( 'QuElFinder'=&gt;array( </code></pre> <p>because as you can see in the QuElFinder controller, in the <code>connectorAction()</code> function, it is reading that configuration, and there is a lot of paths.</p>

<p>the usage of ccc:fid is an extension of the namespace which needs to be declared in xml in order to be able to use it in libraries like simplexml. </p> <p>Here are some examples of descriptions of usin a namespace:</p> <ul> <li><a href="http://www.w3.org/TR/1999/REC-xml-names-19990114/" rel="nofollow noreferrer">http://www.w3.org/TR/1999/REC-xml-names-19990114/</a></li> <li><a href="http://www.w3.org/TR/xml-names/" rel="nofollow noreferrer">http://www.w3.org/TR/xml-names/</a></li> </ul> <p>Hope that helps, albeit it is a little complicated. </p>

<p>In Private Sub DetailsView1_ItemInserting event I changed </p> <p>Dim txtYearPlant As TextBox = DirectCast(DirectCast(sender, DetailsView).FindControl("YearPlant"), TextBox) </p> <p>TO</p> <p>Dim txtYearPlant As TextBox = TryCast(view.FindControl("YearPlant"), TextBox) e.Values.Add("YearPlant", txtYearPlant.Text)</p> <p>So now the value in the PlantYear textbox is saved to the record.</p>

<p>Your replace statement should be a regex string. <code>$</code> indicates the end of a line in regex, to find a dollar sign you need to escape each one with a <code>\</code> so your regex should be <code>\$</code> for each one you want to match.</p> <p>for the rest, just use CSS</p>

<p>for all the googlers coming here - you're probably looking for this:</p> <pre><code>var pad_array = function(arr,len,fill) { return arr.concat(Array(len).fill(fill)).slice(0,len); } </code></pre>

<p>finally figure out the answer, add a custom TypedJsonString class,</p> <pre><code>public class TypedJsonString extends TypedString { public TypedJsonString(String body) { super(body); } @Override public String mimeType() { return "application/json"; } } </code></pre> <p>convert my json object to TypedJsonString,</p> <pre><code>TypedJsonString typedJsonString = new TypedJsonString(jsonObject.toString()); </code></pre> <p>changed the api class as follows,</p> <pre><code>Observable&lt;Item&gt; getListOfFeed(@Body TypedJsonString typedJsonString); </code></pre>

Telegram Bot API: How to avoid Integer overflow in updates id? <p>Telegram bot api get updates function takes last update id as offest parameter. But update id is signed 32bit integer, so it is just 2147483647. Currently my bot receiving update id 348691972. 2147483647 is a small number, for example current China and India population is more then int 32.<br> What will happen when update id will overflow and how to avoid it? Is it some kind of problem 2000?</p>

OleDbCommand and Unicode Char <p>I have an application that run a lot of query using OleDbCommand.

Prevent multiple instances of a given app in .NET? <p>In .NET, what's the best way to prevent multiple instances of an app from running at the same time? And if there's no "best" technique, what are some of the caveats to consider with each solution?</p>

<p>This is one of those cases where type signatures really help. Stare for a second at the type signature: </p> <pre><code>(+=) :: (ArrowXml a) =&gt; a b XmlTree -&gt; a b XmlTree -&gt; a b XmlTree </code></pre> <p>First off, <code>ArrowXml</code> is a subclass of <code>Arrow</code>, which describes some sort of machinery taking some input to some output. You can think of it like a big factory with conveyor belts taking things to different machines, and we're building these factory machines and hence factories with functions. Three of the Arrow combinators, for example, are:</p> <pre><code>(&amp;&amp;&amp;) :: (Arrow a) =&gt; a b c -&gt; a b c' -&gt; a b (c, c') |infixr 3| Fanout: send the input to both argument arrows and combine their output. arr :: (Arrow a) =&gt; (b -&gt; c) -&gt; a b c Lift a function to an arrow. (.) :: (Category cat) =&gt; cat b c -&gt; cat a b -&gt; cat a c morphism composition. </code></pre> <p>Now look at the lowercase letter (type variable) very closely in:</p> <pre><code>(+=) :: (ArrowXml a) =&gt; a b XmlTree -&gt; a b XmlTree -&gt; a b XmlTree </code></pre> <p>Clearly we're taking two machines which turn <code>b</code>s into <code>XmlTree</code>s and "merging them together" into one machine which takes a <code>b</code> in and expels an <code>XmlTree</code>. But importantly, this type signature tells us that more or less the <strong>only</strong> way that this can be implemented is:</p> <pre><code>arr1 += arr2 = arr f . (arr1 &amp;&amp;&amp; arr2) where f :: (XmlTree, XmlTree) -&gt; XmlTree f = _ </code></pre> <p>This is because of "free theorems"; if you don't know the type of a parameter then we can prove that you can't really <em>do</em> much with it. (It can be a little more complicated because the arrow might have structures which aren't totally encapsulated by <code>arr</code>, like internal counters which are summed together with <code>.</code> which are then set to <code>0</code> when using <code>arr</code>. So actually replace <code>arr f</code> with a generic <code>a (XmlTree, XmlTree) XmlTree</code> and you're good to go.)</p> <p>So we must have <strong>parallel execution</strong> of the two arrows here. That's what I'm trying to say. Because the combinator <code>(+=)</code> doesn't know what <code>b</code> is, it has no choice but to blithely feed the <code>b</code> to the arrows in parallel and then try to combine their outputs together. So, <code>deep (hasName "bar")</code> does not look at <code>foo</code>.</p> <p>You can possibly make a mutually recursive solution with <code>deep (hasName "bar") . foo</code> if you really want, but it seems potentially dangerous (i.e. infinite loop), so it may be safer to simply define something like:</p> <pre><code>a ++= b = a += (b . a) </code></pre> <p>where the "current" a is "fed" to b to produce the update. To do this you will have to import <code>.</code> from <code>Control.Category</code> as it is not the same as <code>Prelude..</code> (which does function composition only). This looks like:</p> <pre><code>import Prelude hiding ((.)) import Control.Category ((.)) </code></pre>

<p>First, I'd better do it on SQL Server side :)<br> But if you don't want or cannot to do it on server side you can use this approach:</p> <p>It is obvious that you need to store SessionID somewhere you can create a txt file for that or better some settings table in SQL Server or there can be other approaches.</p> <p>To add columns <code>SessionID</code> and <code>TimeCreated</code> to OLE Destination you can use <a href="http://www.dotnetfunda.com/articles/article1233-use-of-derived-column-in-ssis.aspx" rel="nofollow">Derived columns</a></p>

UIViewController no longer has members topViewController or viewControllers in XCode 7 <p>After updating to XCode 7 and converting my project to the latest Swift 2 syntax, there is one error I cannot seem to fix. I have a segue to a navigation controller and need to pass data to the top view controller in its stack. The following has always worked until now:</p> <pre><code>override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { let destinationVC = segue.destinationViewController.viewControllers[0] as! MYViewController // OR let destinationVC = segue.destinationViewController.topViewController as! MYViewController // ... } </code></pre> <p>But now the compiler gives error: </p> <p><code>Value of type 'UIViewController' has no member 'viewControllers'</code> or <code>Value of type 'UIViewController' has no member 'topViewController'</code></p> <p>I do not see how else to access the view controller(s) on the stack. Any ideas? Thanks in advance!</p>

<p>Take a look at the OpenCV doc:</p> <p>For <a href="http://docs.opencv.org/master/dd/d1a/group__imgproc__feature.html#ga04723e007ed888ddf11d9ba04e2232de" rel="nofollow">Canny</a>:</p> <blockquote> <p><strong>apertureSize:</strong> aperture size for the Sobel operator.</p> </blockquote> <p>And for <a href="http://docs.opencv.org/master/d4/d86/group__imgproc__filter.html#gacea54f142e81b6758cb6f375ce782c8d" rel="nofollow">Sobel</a>:</p> <blockquote> <p><strong>ksize:</strong> size of the extended Sobel kernel; it must be 1, 3, 5, or 7.</p> </blockquote> <p>So the aperture size in <code>Canny</code> is limited by the <code>Sobel</code> kernel size.</p> <p>This is verified in the <a href="https://github.com/Itseez/opencv/blob/master/modules/imgproc/src/canny.cpp#L609-L610" rel="nofollow">source code</a> :</p> <pre><code> if ((aperture_size &amp; 1) == 0 || (aperture_size != -1 &amp;&amp; (aperture_size &lt; 3 || aperture_size &gt; 7))) CV_Error(CV_StsBadFlag, "Aperture size should be odd"); </code></pre> <p>So, unless you rewrite yourself some code, there's no way to use Canny with a larger aperture size. You can apply your custom <em>large sobel filter</em> with <a href="http://docs.opencv.org/2.4/doc/tutorials/imgproc/imgtrans/filter_2d/filter_2d.html" rel="nofollow">filter2d</a>, and then code the Canny non maxima suppression.</p> <p>However, Sobel with mask larger then 3x3 is rarely used in practice.</p>

Does every view have its own canvas/bitmap to draw on? <p>I have a relativelayout with three full screen child views of the same custom view class. I am wondering whether I should be worried about memory. Judging by this answer: <a href="http://stackoverflow.com/questions/4576909/understanding-canvas-and-surface-concepts">Understanding Canvas and Surface concepts</a></p> <p>All views get passed the same canvas with underlying bitmap to draw on so that the memory is not tripled. Can anyone confirm? It would make sense, otherwise a full screen textview would be very inefficient. </p> <p>Bonus: is the purpose of canvas to define a drawable area of a bitmap and translating the view coordinates to bitmap coordinates?</p>

MySQL REPLACE rows WHERE field a equals x and field b equals y <p>I'm trying to construct a 'new comments' feature where the user is shown the number of new comments since the last visit.

<p>JayData does <strong>NOT</strong> track complex types (like arrays or custom type objects) inner values.. It just tracks the reference to the value.</p> <p>In case you want to force the update in this case, you have to make a "deep copy" or encapsulate you current object into another one for the reference to change. For example using jQuery:</p> <pre><code>entity.field = jQuery.extend({}, field); </code></pre> <p>Nothing really changes for your object values, but it gets encapsulated in jQuery's object and the reference has changed, so JayData thinks it's value has changed and sends the updated values to the server.</p> <p>It is a workaround, but as my friend said: "Do you really care about how much <strong><em>clients'</em></strong> CPU you use?" :)</p>

<p>Maybe an idea which might work for you:</p> <p>To ban a user, create an entry in your database to the user to flag the user as banned with a timestamp NOW + X</p> <pre><code>{ "users" : { "bad_user" : { "banned" : { "until" : 123456 // timestamp NOW + X } } } } </code></pre> <p>Now whenever the user logs in afterwards, you check wether the user is banned and immediately try to delete that entries. If it fails, penalty time is still running. If it succeeds, well then the user can use your app :)</p> <p>The trick is to use firebase rules to restrict possible changes.</p> <p>something like:</p> <pre><code>{ "rules" : { "users" : { "$uid" : { // ... "banned" : { .write : "(!newData &amp;&amp; now &lt; data.child('until').val() )" .... </code></pre> <p>Please note - these are not working rules, but should help to figure it out.</p>

<p>That's the simplest way to do it; don't be disappointed.</p>

Express & Passport with multiple subdomains <p>I'm merging two little apps into one, that is supposed to be accessed via two subdomains. To do so I'm using the module "express-subdomain". I'm trying to use Passport so when a user logs in in the first app, he is logged in in both apps. However using <code>req.isAuthenticated()</code> I can indeed login in the "first" app, but then I'm not in the "second" one.</p> <p>I'm searching for any solution to have a passport authentification in the first subdomain and being logged in in the second one, including keeping two disctinct apps if needed.</p> <p>Assuming that passport is correctly configured for a local strategy, as well as the routers and the rest of the app. Here is what it looks like :</p> <p><strong>app.js</strong></p> <pre><code>// &lt;- requires etc var passport = require('./configurePassport.js')(require('passport')); var app = express(); app.use(cookieParser()); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({extended: true})); app.use(expressSession({ secret: 'bestSecretEver', resave: false, saveUninitialized: false })); app.use(passport.initialize()); app.use(passport.session()); // and others var firstRouter = express.Router(); firstRouter.use('/public', express.static(__dirname + '/first/public')); firstRouter.use(favicon(__dirname + '/first/public/favicon.ico')); // &lt;- setting first router's GET, POST etc app.use(subdomain('sub1', firstRouter)); // for sub1.example.com var secondRouter = express.Router(); secondRouter.use('/public', express.static(__dirname + '/second/public')); secondRouter.use(favicon(__dirname + '/second/public/favicon.ico')); // &lt;- setting second router's GET, POST etc app.use(subdomain('sub2', secondRouter)); // for sub2.example.com </code></pre> <p>Any idea ?</p>

<p>You can use a form inside your application. And, ask users to fill that form. The forms needs to be connected to an database server. You may use 000webhost.com (free) to create your database. Just populate the table in database from the user response. For this follow the following procedure: <br>1. Create a online database (000webhost.com) <br>2. Write php code to insert data into the database form and save that php on the file manager on server. <br>3. From android create a async task to execute that php. <br>4. Pass your parameter or user response as request attributes while executing the php. <br>5. php will save user's response on your server. <br> Now you can access that database from anywhere.</p> <p>Note: This may require an internet connection in application.</p>

Integrate an E-Mail server into ASP.NET <p>I've a general design question:<br /> <br /> I have a mailserver, written in C#.<br /> Then I have a web forum software, written in for ASP.NET in C#.<br /> <br /> Now I'd like to integrate the mailserver into the ASP.NET forum application. For example, I'd like to make it possible that one can create a mailinglist from the forum, and give users the oportunity to add oneselfs to the mailinglist members in the forum, and then add the new list-members to the respective mailinglist on the server.</p> <p>Since the server is a separate console/winforms/service application, I first thought I'd best use .NET remoting for this.</p> <p>But my second thought was, that some users might host their forum on a host where <br /> (a) they don't have a virtual machine where they can do what they want<br /> (b) the admin of the host might not want to install an additional mailserver or charge extra for this<br /> (c) the user might have a service plan that only permits to add a web-application, not external programs (very likely)<br /> <br /><br /> Now, I wanted to ask:<br /> Is it possible to fully integrate a mailserver into an ASP.NET application somehow ? (I have the full source of the server + ASP.NET application)</p> <p>Well, it probably won't be a page or a ashx handler, but something like a http module ? Or what's the general way to integrate TCP/IP applications into asp.net ? (Of course I'm assuming the respecive ports are available/forwarded - and I'll make it possible to also run it with the e-mail server as external application)</p>

Why invariant generic type parameterized with subclass of upper bounds fails to conform? <p>Given:</p> <pre><code>class Invar[T] trait ExtendsAnyref extends AnyRef def f(a: Invar[ExtendsAnyref]) = {} </code></pre> <p>The following is erroneous</p> <pre><code>scala&gt; val x: Function1[Invar[_ &lt;: AnyRef], Unit] = f &lt;console&gt;:13: error: type mismatch; found : Invar[ExtendsAnyref] =&gt; Unit required: Invar[_ &lt;: AnyRef] =&gt; Unit val x: Function1[Invar[_ &lt;: AnyRef], Unit] = f ^ </code></pre> <p>Why?</p> <p>I understand that in Scala, generic types have by default nonvariant subtyping. Thus, in the context of this example, instances of <code>Invar</code> with different type parameters would never be in a subtype relationship with each other. So an <code>Invar[ExtendsAnyref]</code> would not be usable as a <code>Invar[AnyRef]</code>.</p> <p>But I am confused about the meaning of <code>_ &lt;: AnyRef</code> which I understood to mean "some type below <code>AnyRef</code> in the type hierarchy." <code>ExtendsAnyref</code> is some type below <code>AnyRef</code> in the type hierarchy, so I would expect <code>Invar[ExtendsAnyref]</code> to conform to <code>Invar[_ &lt;: AnyRef]</code>.</p> <p>I understand that function objects are contravariant in their input-parameter types, but since I use <code>Invar[_ &lt;: AnyRef]</code> rather than <code>Invar[AnyRef]</code> I understood, apparently incorrectly, the use of the upper bounds would have the meaning "<code>Invar</code> parameterized with <code>Anyref</code> or any extension thereof."</p> <p>What am I missing?</p>

<p>To allow nice zooming you should add this line to the two you show:</p> <pre><code>chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Zoomable = true; </code></pre> <p>Here is a function to calculate an average of the visible points' 1st YValues:</p> <pre><code>private void chart1_AxisViewChanged(object sender, ViewEventArgs e) { // for a test the result is shown in the Form's title Text = "AVG:" + GetAverage(chart1, chart1.Series[0], e); } double GetAverage(Chart chart, Series series, ViewEventArgs e) { ChartArea CA = e.ChartArea; // short.. Series S = series; // references DataPoint pt0 = S.Points.Select(x =&gt; x) .Where(x =&gt; x.XValue &gt;= CA.AxisX.ScaleView.ViewMinimum) .DefaultIfEmpty(S.Points.First()).First(); DataPoint pt1 = S.Points.Select(x =&gt; x) .Where(x =&gt; x.XValue &lt;= CA.AxisX.ScaleView.ViewMaximum) .DefaultIfEmpty(S.Points.Last()).Last(); double sum = 0; for (int i = S.Points.IndexOf(pt0); i &lt; S.Points.IndexOf(pt1); i++) sum += S.Points[i].YValues[0]; return sum / (S.Points.IndexOf(pt1) - S.Points.IndexOf(pt0) + 1); } </code></pre> <p>Note that the <code>ViewEventArgs</code> parameter is providing the values of the position and size of the View, but these are just the <code>XValues</code> of the datapoints and not their indices; so we need to search the <code>Points</code> from the left for the 1st and from right for the last point.</p> <p><strong>Update</strong> Sometimes the zooming runs into a special problem: When the data are more finely grained than the default <code>CursorX.IntervalType</code> it just won't let you zoom. In such a case you simply have to adapt to the scale of your data, e.g. like this: <code>CA.CursorX.IntervalType = DateTimeIntervalType.Milliseconds;</code></p>

<h2>Focus Handling</h2> <p>Focus movement is based on an algorithm which finds the nearest neighbor in a given direction.

What's wrong with my logic (Java syntax) <p>I'm trying to make a simple program that picks a random number and takes input from the user.

<p>Actually an array is a fixed pointer to the first element in the array (I think this is known as an L-value). This means your assignments at the end for the tempState, currState and nextState cannot work (as you have discovered).</p> <p>After declaring space for the 2 2d-arrays, you could then declare pointers to the 2d arrays which you might be able to work in a reasonable way. To use the pointers for indexing into the 2-d array, the compiler would need to be aware of the size of the last dimension(s) of the array.</p>

Getters, Setters and Constructors in Java - Making a car and stocking it <p>I'm trying to create a class in Java using BlueJ. My class is named Automobile. My goal is to be able to use my Constructor method to create cars with the variables: year, color, brand, number of doors, number of kilometers, if it's automatic (boolean), if it's sold (boolean), a description, and an identification number. All the variables have a set default value, a minimum and a maximum accepted value.</p> <p>I have to use getVariablename and setVariablename for my methods. My color and brand variables are int, and I made methods to retrieve their String counterparts in a table in my class. </p> <p>My issue is I don't understand the principle of setting my variable in one method and getting it in another (while making sure it's an accepted value). Also, once I have my Setter and Getter method, what do I have to write down in the creation of my Constructor method?</p> <p>Up to now, I have this :</p> <pre><code>public class Automobile { private static final String[] COLORS = { "Other", "Noir", "Blanc", "Bleu Nuit", "Bleu Clair", "Vert Pomme", "Vert Bouteille", "Taupe", "Argent", "Sable"}; private static final String[] BRANDS = { "Autre", "Mazda", "Toyota", "Ford", "GM", "Hyunday", "BMW", "SAAB", "Honda"}; public static final int COLOR_DEF = 8; public static final int COLOR_MIN = 0; public static final int COLOR_MAX = COULEURS.length - 1; public static final int BRAND_DEF = 4; public static final int BRAND_MIN = 0; public static final int BRAND_MAX = MARQUES.length - 1; public static final double KILO_DEFAULT = 55000; public static final double KILO_MIN = 15000; public static final double KILO_MAX = 140000; public static final int TWO_DOORS = 2; public static final int FOUR_DOORS = 4; public static final int DOORS_DEFAULT = FOUR_DOORS; public static final boolean AUTO_DEF = true; public static final int YEAR_MIN = 1997; public static final int YEAR_MAX = 2016; public static final int YEAR_DEFAUT = 2007; public static final String COMM_DEFAUT = ""; public static String color (int cou) { String chainecolor = ""; if (cou &gt;= COLOR_MIN &amp;&amp; cou &lt;= COLOR_MAX) { chainecolor = COLORS[cou]; } return chainecolor; } //This method is to return the String value of a color from its int value using the COLORS table. If invalid it returns an empty chain. public static String brand (int br) { String chainebrand = ""; if (ma &gt;= BRAND_MIN &amp;&amp; ma &lt;= BRAND_MAX) { chainebrand = BRANDS[br]; } return chainebrand; } //same thing for the brand public Automobile (int brand, int year, int color, boolean automatic, double kilometers,int nbrDoors, String description, boolean sold){ //To be completed } //here i'm supposed to create getters that return int values for everything but automatic, sold and description public void setYear ( int year ) { if (year &gt;= YEAR_MIN &amp;&amp; YEAR &lt;= YEAR_MAX) { year = year; } } // supposed to be the setter for my year, as long as it's within the accepted values public void setMarque (int brand){ if (brand &gt;= BRAND_MIN &amp;&amp; brand &lt;= BRAND_MAX) { brand = brand; } } //same, for the brand public void setColor (int color) { if (color &gt;= COLOR_MIN &amp;&amp; color &lt;= COLOR_MAX){ color = color; } }// same for the color public void setNbrDoors (int p) { if (p == TWO_DOORS || p == FOUR_DOORS){ p = p; } } // same for the door. I am forced to use (int p) as the variable for this method, which confuses me as to how I will refer to it from nbrDoors up in the Automobile constructor method } // Automobile </code></pre> <p>So my difficulties lie in: </p> <ul> <li><p>Are the examples of setters that I made valid for this purpose? I do not understand the need for p = p, or color = color...</p></li> <li><p>How do I create a getter method that will be able to go pick up the Variable p from setNbrDoors, return its value and have it be used for nbrDoors in the Automobile constructor?</p></li> <li><p>What am I supposed to write in the Constructor method, such as it will be able to get its values from the getters?</p></li> </ul> <p>This is all because the second part is I will have to create a little code to ask the user to input all the values for variables, then create a table to stock the Cars the user creates.</p> <p>P.S.: the work is originally in french, so I translated the variable and method names best I could for your better understanding. Also, the variable names, methods, etc are all imposed, I am FORCED to make the class this way exactly.</p> <p>EDIT: As such, the use of static for brand and color conversion are also imposed. Those 2 methods are solely for returning a String of character from an int value. they are not used in the Constructor. Finally, the exceptions will be handled in the second part of the work using a separate validation loop. The Automobile class is really used solely to handle the creation of the "car" object.</p>

<p>While you can change the VM sizes now as part of an in-place update, you should expect some instance downtime. The Windows Azure fabric controller will walk the upgrade domains, taking 1 upgrade domain down to change the VM sizes, and then moving on to the next. If you have 2 instances, you shouldn't have noticed an entire outage (just 1 machine going down at a time).</p> <p>You can see some further details at <a href="http://msdn.microsoft.com/en-us/library/windowsazure/hh472157.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windowsazure/hh472157.aspx</a>. </p>

<p>Neo4j does not support storing another object as a nested property. Neo4j-OGM only supports </p> <blockquote> <p>any primitive, boxed primitive or String or arrays thereof, essentially anything that naturally fits into a Neo4j node property. </p> </blockquote> <p>If you want to work around that, you may need to create a custom type convertor. For example, </p> <pre><code>import org.neo4j.ogm.typeconversion.AttributeConverter class XYZ{ XYZ(Integer x, String y) { this.x = x this.y = y } Integer x String y } public class XYZConverter implements AttributeConverter&lt;XYZ, String&gt; { @Override public String toGraphProperty(XYZ value) { return value.x.toString() + "!@#" + value.y } @Override public XYZ toEntityAttribute(String value) { String[] split = value.split("!@#") return new XYZ(Integer.valueOf(split[0]), split[1]) } } </code></pre> <p>You can then annotate the @NodeEntity with a @Convert like this</p> <pre><code>@NodeEntity class Node { @GraphId Long id; @Property String name @Convert(value = XYZConverter.class) XYZ xyz } </code></pre> <p>On the flip side, its not a good practice to do this, since ideally you should link Node and XYZ with a 'hasA' relationship. Neo4j has been designed to optimally handle such kind of relationships, so it would be best to play with to strengths of neo4j</p>

<p>You cannot use <code>document.write()</code> once the document is loaded. Doing so will cause the entire document to be cleared and a new one started. If you want to add text to a document that has already been loaded, then you can use the appropriate jQuery methods to modify existing elements or add new ones.</p> <p>To help you with the exact code, we would need to see your HTML and a more complete description of exactly what you're trying to add to it.</p> <p>As some examples, one can add objects to an element with the <code>.append()</code> jquery method or using the <code>.html()</code> method.</p>

<p>i was struggling a while back with the same problem. i was following ryan bates screencast on delayed_job and got the same error 'uninitialized constant Delayed::Job'. In the screencast ryan creates a file called mailing_job.rb(located under lib folder) with the delayed_job perform method inside, which allows you to use the enqueue method. After doing some research i found that rails 3 does not automatically load the lib folder files into your app.(not entirely sure)<br /></p> <p>Try this<br /> In your controller where you use this:<br /></p> <pre><code>"Delayed::Job.enqueue do_it(), 0, 1.minutes.from_now.getutc" </code></pre> <p>Try to require the file like this. <br /></p> <pre><code>require 'mailing_job' class AssetsController &lt; ApplicationController def some_method Delayed::Job.enqueue do_it(), 0, 1.minutes.from_now.getutc end end </code></pre>

<p>In the usual case destructor is not caused for objects created in <strong><code>main()</code></strong>.

I'd like to be sure the path ends with a <code>/</code>.</p> <p>In this moment I have a method in the entity that uses this path (yes is an entity and not a controller) adjust the configuration parameter with a code like this:</p> <pre><code>public function buildLogoFolder($folder) { // Replace the placeholder with the current Entity's URL $folder = str_replace('{entity_domain}', $this-&gt;getDomain()-&gt;getCanonical(), $folder); $folder = rtrim(ltrim($folder, '/'), '/') . '/'; return $folder; } </code></pre> <p>As the <code>$folder</code> parameter comes from the <code>config.yml</code> file I'd like to move outside of the entity this adjustment.</p> <p>I think I should use a solution similar to the one suggested <a href="http://stackoverflow.com/questions/14651871/how-to-dynamically-append-sections-to-symfony-2-configuration">here</a>, that is the use of the <code>DependencyInjection</code> component.</p> <p>I think the process is very similar to the <a href="http://symfony.com/doc/current/cookbook/bundles/extension.html" rel="nofollow">loading of</a> a <a href="http://symfony.com/doc/current/cookbook/bundles/configuration.html" rel="nofollow">configuration file</a> for a new bundle as explained in the Symfony's documentation but I'm not sure on how to proceed.</p> <p>Is there someone who can put me on the right way?</p> <p><strong>I'd like to automate the process. I want read the <code>folder</code> configuration parameter value and then adjust it with the method I wrote above.</strong></p> <p><strong>I want to be sure that the <code>folder</code> parameter configured ever ends with a trailing slash, also if the developer didn't write it in the configuration.</strong></p> <p><strong>So, If the developer write something like <code>path/to/folder</code> the resulting configuration parameter is automatically adjusted to <code>path/to/folder/</code></strong>.</p>

<p>If you select only HEAD, than any changes in any revisions prior to HEAD will not be included in the merge. You either need to select ALL the revisions in the branch whose changes are not yet included in your branch, or leave the range specifier empty to allow SVN to figure out which revisions to merge.</p> <p><strong>Edited to add example</strong></p> <p>When you do a "range of revisions" merge, you are picking individual CHANGES to cherry-pick over into your merge destination. If you say "merge HEAD" you are not saying "merge all changes up through HEAD", you are saying "merge only the specific change that happened in the very last revision on that branch". Consider a trunk with revision 122; a MayBranch with revisions 123, 124, and 125; and an AugustBranch with revisions 126 and 127. Both branches were copied from trunk revision 122.</p> <p>You want all three changes on the MayBranch&ndash;123, 124, and 125&ndash;to be merged into your AugustBranch. If you select all three revisions, or leave the revision specifier empty, this will happen. The merge will use revision 122 on trunk as the BASE, with 125 on MayBranch as source revision, and 127 on AugustBranch as destination revision.</p> <p>If instead you select HEAD as the revision to merge, SVN will use revision 124 on MayBranch as the BASE, with 125 as the source revision and 127 as destination as before. Since BASE is now the place where revision 125's changes were started from, you only get the changes that specifically happened in revision 125.</p> <p>The final result is as if you had exported only revision 125 on MayBranch as a diff, and then applied that diff to the AugustBranch. Except this is done with merge tracking information included so that SVN knows how to get the whole branch automatically later if you like.</p>

How to enable MySQL client auto re-connect with MySQLdb? <p>I came across PHP way of doing the trick:</p> <pre><code>my_bool reconnect = 1; mysql_options(&amp;mysql, MYSQL_OPT_RECONNECT, &amp;reconnect); </code></pre> <p>but no luck with MySQLdb (python-mysql).</p> <p>Can anybody please give a clue? Thanks.</p>

Clear upper bytes of __m128i <p>How do I clear the <code>16 - i</code> upper bytes of a <code>__m128i</code>?</p> <p>I've tried this; it works, but I'm wondering if there is a better (shorter, faster) way:</p> <pre><code>int i = ... // 0 &lt; i &lt; 16 __m128i x = ... __m128i mask = _mm_set_epi8( 0, (i &gt; 14) ? -1 : 0, (i &gt; 13) ? -1 : 0, (i &gt; 12) ? -1 : 0, (i &gt; 11) ? -1 : 0, (i &gt; 10) ? -1 : 0, (i &gt; 9) ? -1 : 0, (i &gt; 8) ? -1 : 0, (i &gt; 7) ? -1 : 0, (i &gt; 6) ? -1 : 0, (i &gt; 5) ? -1 : 0, (i &gt; 4) ? -1 : 0, (i &gt; 3) ? -1 : 0, (i &gt; 2) ? -1 : 0, (i &gt; 1) ? -1 : 0, -1); x = _mm_and_si128(x, mask); </code></pre>

<p>Most of the answers here I don't think are really going to wow anyone, especially a tech crowd. They might be surprised that Perl can do it, but they aren't going to be surprised that you can do the task. However, even if they aren't surprised that you can do it, they might be surprised how fast, or with how little code, you can do it.</p> <p>If you're looking for things to show them that will wow them, you have to figure out what they think is hard in their jobs and see if Perl could make it really easy. I find that people tend not to care if a language can do something they don't already have an interest in. That being said, impressing anyone with Perl is the same as impressing anyone in any other subject of field: you have to know them and what they will be impressed by. You have to know your audience.</p> <p>Perl doesn't really have any special features that allow it to do any one thing that some other language can also do. However, Perl combines a lot of features that you usually don't find in the same programming language.</p> <p>Most of the things that I'm impressed by have almost nothing to do with the language:</p> <ul> <li><p>There's a single codebase that runs on a couple hundred different platforms, despite differences in architecture.</p></li> <li><p>Perl's <a href="http://search.cpan.org/" rel="nofollow noreferrer">CPAN</a> is still unrivaled among other languages (which is really sad because it's so easy to do the same thing for other languages).</p></li> <li><p>The testing culture has really raised the bar in Perl programming, and there's a lot of work that teases out platform dependencies, cross-module issues, and so on without the original developer having to do much.</p></li> </ul>
