• Capturing stdout within the same process in Python

  - by danben

  I've got a python script that calls a bunch of functions, each of which writes output to stdout. Sometimes when I run it, I'd like to send the output in an e-mail (along with a generated file). I'd like to know how I can capture the output in memory so I can use the email module to build the e-mail. My ideas so far were: use a memory-mapped file (but it seems like I have to reserve space on disk for this, and I don't know how long the output will be) bypass all this and pipe the output to sendmail (but this may be difficult if I also want to attach the file)

• Search dir using wildcard string, return filename, and loop.

  - by Charlie Murphy

  Hello all, I'm having some problems, and looking for some help. I'm trying to create a photo gallery in javascript, that will be able to 'update' it's self automatically. I need to be able to search a directory, and grab a file with a specific prefix. I need to output the followng HTML code: <li><a href="images/resize_FILENAME.ext"><img src="images/thumb_FILENAME.ext"></a></li> The 'resize_' and 'thumb_' use a timestamp to identify, so they have the same ending, just a different prefix. So, for example, if I search the directory for an image with a prefix of 'resize_', I need to insert that into the a tag, and then remove the '_resize' prefix, and add the '_thumb' prefix for the img tag. I then need to be able to do that for each image in the directory. Any help would be greatly appreciated. Oh, I should add: I'm assuming php would be easiest for this, but if an alternative exists that would work too. I'm also using jQuery if javascript would be better.

• How can a Delphi TPersistent object calculate its own deserialization time?

  - by mjustin

  For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

• Java class Class<T> and static method Class.forName() drive me crazy.

  - by matt

  Hi, this code doesn't compile. i'm wandering what i am doing wrong: private static Importable getRightInstance(String s) throws Exception { Class<Importable> c = Class.forName(s); Importable i = c.newInstance(); return i; } where Importable is an interface and the string s is the name of an implementing class. The compiler says: ./Importer.java:33: incompatible types found : java.lang.Class<capture#964 of ?> required: java.lang.Class<Importable> Class<Importable> c = Class.forName(format(s)); thanks for any help!

• Self hosted WCF console output from service

  - by user989056

  quick one: Is it possible to capture the output stream of a WCF service that is hosted via ServiceHost ( self hosted service) ? I have methods within my WCF service that output useful debugging information, is it possible to send these to it's host's console output? Edit: It appears that I have made an obvious blunder - I was using Debug instead of Console. It is possible to output to the console by using the standard Console output commands in your WCF service class. I have marked the answer that I have found the most useful.

• jCarousel - achieving an active state AND wrap:circular

  - by swisstony

  Hey folks A while back I implemented the jCarousel image solution for a client that required a numbered active state. After a bit of googling a found the answer but noticed that the preferred circular option would not work. What would happen is that once the carousel had cycled through all its (5) images, upon the return to the first, the active state would be lost, because, according to jcarousel it was actually the 6th (the index just keeps on incrementing). I just went ahead and instead used wrap:'both' which at least had a correctly functioning active state. However now the client says they dont like this effect and simply want the animation to return to position 1 after the final image. This means I need to get'wrap: 'both' working somehow. Below is my current code. Can someone please solve this one, as its a little above my head! function highlight(carousel, obejctli,liindex,listate){ jQuery('.jcarousel-control a:nth-child('+ liindex +')').attr("class","active"); }; function removehighlight(carousel, obejctli,liindex,listate){ jQuery('.jcarousel-control a:nth-child('+ liindex +')').removeAttr("class","active"); }; jQuery('#mycarousel').jcarousel({ initCallback: mycarousel_initCallback, auto: 5, wrap: 'both', vertical: true, scroll: 1, buttonNextHTML: null, buttonPrevHTML: null, animation: 1000, itemVisibleInCallback: highlight, itemVisibleOutCallback: removehighlight }); }); Thanks in advance

• penetration of web 2.0 features amongst users?

  - by user151841

  I have a survey web-app that is public facing. I want to set up automated testing with Selenium, but selenium can't capture javascript alerts that we're currently using on the site. I'm thinking about changing our user-facing error notifications to some web 2.0 javascript library so that it is accessible to Selenium. However, I'm not sure how many of our users would be able to experience them properly. How backwards-compatible do I need to be in the present day? I have collected a database of actual user-agent strings of our users. I asked here how I could group them into meaningful data about what browsers our users are actually using.

• Plotting Points in Java with Interaction

  - by mellort

  I have a large number of data points which are two dimensional coordinates with non-integer values (floats). I am looking for a Java library that can help me plot these points, allowing for custom point size, color, and labels. Further, I would like the user to be able to interact with the points with panning and zooming, and I want to be able to capture KeyEvents from the user. Processing looks great for what I want, but I don't want to do everything from scratch. Is there a better solution? Thanks in advance.

• Custom UIProgressView drawing weirdness

  - by Werner

  I am trying to create my own custom UIProgressView by subclassing it and then overwrite the drawRect function. Everything works as expected except the progress filling bar. I can't get the height and image right. The images are both in Retina resolution and the Simulator is in Retina mode. The images are called: "[email protected]" (28px high) and "[email protected]" (32px high). CustomProgressView.h #import <UIKit/UIKit.h> @interface CustomProgressView : UIProgressView @end CustomProgressView.m #import "CustomProgressView.h" @implementation CustomProgressView - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // Initialization code } return self; } // Only override drawRect: if you perform custom drawing. // An empty implementation adversely affects performance during animation. - (void)drawRect:(CGRect)rect { // Drawing code self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.frame.size.width, 16); UIImage *progressBarTrack = [[UIImage imageNamed:@"progressBarTrack"] resizableImageWithCapInsets:UIEdgeInsetsZero]; UIImage *progressBar = [[UIImage imageNamed:@"progressBar"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 4, 5, 4)]; [progressBarTrack drawInRect:rect]; NSInteger maximumWidth = rect.size.width - 2; NSInteger currentWidth = floor([self progress] * maximumWidth); CGRect fillRect = CGRectMake(rect.origin.x + 1, rect.origin.y + 1, currentWidth, 14); [progressBar drawInRect:fillRect]; } @end The resulting ProgressView has the right height and width. It also fills at the right percentage (currently set at 80%). But the progress fill image isn't drawn correctly. Does anyone see where I go wrong?

• Retain cycle on `self` with blocks

  - by Jonathan Sterling

  I'm afraid this question is pretty basic, but I think it's relevant to a lot of Objective-C programmers who are getting into blocks. What I've heard is that since blocks capture local variables referenced within them as const copies, using self within a block can result in a retain cycle, should that block be copied. So, we are supposed to use __block to force the block to deal directly with self instead of having it copied. __block typeof(self) bself = self; [someObject messageWithBlock:^{ [bself doSomething]; }]; instead of just [someObject messageWithBlock:^{ [self doSomething]; }]; What I'd like to know is the following: if this is true, is there a way that I can avoid the ugliness (aside from using GC)?

• Replace string with incremented value

  - by Andrei

  Hello, I'm trying to write a CSS parser to automatically dispatch URLs in background images to different subdomains in order to parallelize downloads. Basically, I want to replace things like url(/assets/some-background-image.png) with url(http://assets[increment].domain.com/assets/some-background-image.png) I'm using this inside a class that I eventually want to evolve into doing various CSS parsing tasks. Here are the relevant parts of the class : private function parallelizeDownloads(){ static $counter = 1; $newURL = "url(http://assets".$counter.".domain.com"; The counter needs to be reset when it reaches 4 in order to limit to 4 subdomains. if ($counter == 4) { $counter = 1; } $counter ++; return $newURL; } public function replaceURLs() { This is mostly nonsense, but I know the code I'm looking for looks somewhat like this. Note : $this-css contains the CSS string. preg_match("/url/i",$this->css,$match); foreach($match as $URL) { $newURL = self::parallelizeDownloads(); $this->css = str_replace($match, $newURL,$this->css); } }

• How to disable WM6.5.3 gestures?

  - by Duncan Watts

  I am working on a .NET 2.0 application targetting the WM5 SDK, what is the correct way to disable the gesture functionality when running on a WM6.5.3 device that only affects the forms I am using? This is causing an issue when I have a signature capture control inside a tab control - when the signature is entered it's quite common for the tab control to switch tabs as WM6.5.3 picks it up as a gesture. I don't want to disable the gesture functionality device wide, nor can I upgrade the application to target the WM6.5.3 SDK as it still needs to work on older devices. Cheers

• How to enumerate word document using office interop API?

  - by Shekhar

  Hello everyone, I want to traverse through all the elements of an word document one by one and according to type of element (header, sentence, table,image,textbox, shape, etc.) I want to process that element. I tried to search any enumerator or object which can represent elements of document in office interop API but failed to find any. API offers sentences, paragraphs, shapes collections but doesnt provide generic object which can point to next element. For example : <header of document> <plain text sentences> <table with many rows,columns> <text box> <image> <footer> (Please imagine it as a word document) So, now I want some enumerator which will first give me <header of document>, then on next iteration give me <plain text sentences>, then <table with many rows,columns> and so on. Does anyone knows how we can achieve this? Is it possible? I am using C#, visual studio 2005 and Word 2003. Thanks a lot

• What are possible/good ways to prototype iPhone applications?

  - by Ted Johnson

  This is intentionally left broad. If you wanted to show users what iPhone/mobile applications could to for them. The more interactive the better, but it must be quick to build as you can't code up every idea. Let us assume real-time games are out of scope. Throw out ideas or state which approach would be best. Here are some of my ideas, what are yours? Hack a app that loads mostly web or image content, but has hyperlinks to get around in. This would mean static data. Build screens which look great but can only be navigated in a story board type fashion. Load the web version or equivalent on the iPhone and say: now image the buttons and navigation is better. A paper based prototype. Flash or video walk through running on the phone. String existing iPhone apps and web pages together with minimal glue just to convey the idea. Can anyone share prototyping methods for other mobile devices? Ex: The palm prototype was just a block of wood and note pad that was carried around.

• (Visual) C++ project dependency analysis

  - by polyglot

  I have a few large projects I am working on in my new place of work, which have a complicated set of statically linked library dependencies between them. The libs number around 40-50 and it's really hard to determine what the structure was initially meant to be, there isn't clear documentation on the full dependency map. What tools would anyone recommend to extract such data? Presumably, in the simplest manner, if did the following: define the set of paths which correspond to library units set all .cpp/.h files within those to belong to those compilation units capture the 1st order #include dependency tree One would have enough information to compose a map - refactor - and recompose the map, until one has created some order. I note that http://www.ndepend.com have something nice but that's exclusively .NET unfortunately. I read something about Doxygen being able accomplish some static dependency analysis with configuration; has anyone ever pressed it into service to accomplish such a task?

• Removing empty space with jQuery after deleting Selectable item

• Pass HTML form entries into a Javascript array to then be written to a client side cookie?

  - by Tom

  I'm building a bit of a test-case JS application, something very basic, but have run into some problems. I'm trying to use a HTML form for a user to enter a number, which is then written to a Javascript Array. The user then has the option to write that same array to a local (client side) cookie. (I understand the security implications of this - it's a test-case and not for commercial use.) However, I can't make the connection - how can I capture the HTML entry, press 'submit' which will send it to a JS array, where the user can then press a different 'submit' which will write the array to a text file? If anyone can help I'd appreciate it because it's been nearly 6 hours and it's not funny anymore.

• if else on javascript with the value of a select box (pure javascript)

  - by user983248

  I'm working on a select box that have images instead of text, (on the background with css). <script type="text/javascript"> function onChange(element) { element.style.backgroundColor = "Yellow"; element.className = "on_change"; } </script> <select onchange="onChange(this);"> <option value="1" style="background: url(/one.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> <option value="2" style="background: url(/two.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> <option value="3" style="background: url(/three.png) no-repeat scroll 0 0 transparent; width:32px; height:32px;"></option> </select> The problem is how do I get the value of the selected option and if is 1 set one image and if it is two set another image as the background using pure javascript (no jQuery)? I know that selectedIndex is the key to my problem, but I'm clueless of how to use it or how to use it on an if else statement. The script above is just one of my trials, I actually use the script above to perform the same task. <select onchange="this.style.backgroundColor=this.options[this.selectedIndex].style.backgroundColor; this.style.color=this.options[this.selectedIndex].style.color">

• OpenSSH connection trouble

  - by gnostical

  Hi, I'm trying to use Putty 0.60 to log in to an OpenSSH 5.3 server. Connections with openssh from another Linux server are possible, but Putty fails. Putty's event log tells me "software caused connection abort" right after the DH key exchange, the server log doesn't report anything (set to INFO). I analyzed the traffic with Wireshark and got a whole bunch of "TCP retransmission" and "TCP DUP ACK" after said key exchange. Sometimes I was able to log in, but at some point (usually < 2 min.) the connection froze without any logged messages. Sadly, I didn't capture a trace. The server is my own (Funtoo with genkernel and gentoo-sources 2.6.34), so I may tweak it, but I'd still like to know what causes the error. Any suggestions? Thank you!
