• Compressing as GZip WCF requests (SOAP and REST)

  - by Joannes Vermorel

  I have a .NET 3.5 web app hosted on Windows Azure that exposes several WCF endpoints (both SOAP and REST). The endpoints typically receive 100x more data than they serve (lot of data is upload, much fewer is downloaded). Hence, I am willing to take advantage from HTTP GZip compression but not from the server viewpoint, but rather from the client viewpoint, sending compressed requests (returning compressed responses would be fine, but won't bring much gain anyway). Here is the little C# snippet used on the client side to activate WCF: var binding = new BasicHttpBinding(); var address = new EndpointAddress(endPoint); _factory = new ChannelFactory<IMyApi>(binding, address); _channel = _factory.CreateChannel(); Any idea how to adjust the behavior so that compressed HTTP requests can be made?

• Regular expressions and matching URLs with metacharacters

  - by James P.

  I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions? Edit: The original intent was to match all URLs that could be found after the first semi colon.

• SharePoint Cannot Log in after making entry in hosts file

  - by bmw0128

  I'm building a MOSS 2007 site on Windows 2008 R2, 64 bit. Not wanting to use my machine name or IP in the URL, I made an entry in my hosts file: 127.0.0.1 mydev.com I can surf to the URL, http://mydev.com, but when I try to log in (Windows Authentication), I am denied. I am able to successfully log in if I take out the hosts file entry, and surf to http:// Do I need to edit something else for the authentication to work when I want to use a custom URL like mydev.com that is only mapped in the hosts file?

• jQuery draggable leaving cloned html behind

  - by Alex Crooks

  I am using jQuery UI; Draggable http://jqueryui.com/demos/draggable invoked like this: $(document).ready(function(){ $("#side_bar").sortable({ revert: true }); $(".draggable").draggable({ containment: 'parent', hascroll: true, handle: 'div.box_header', scrollSensitivity: 100, scrollSpeed: 100, axis: 'y', connectToSortable: '#side_bar', helper: 'clone', opacity: 0.35 }); }); You can see the html structure on http://www.sarsclan.co.uk (right side bar area). It seems to create a transparant clone as your dragging, but when you drop it puts the draggable div in the right place, but leaves the original div in it's place and just appends the dom with a clone of that original div in its new place.

• How to strip a GET property from the URL using PHP

  - by James

  I have the following function that get's the current page URL: <?php // get current page url function currentPageUrl() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } echo $pageURL; } ?> Which prints: http://localhost/gallery.php?id=23&type=main I want to remove "&type=main" which is present in the url. So before echoing $pageURL I add the following line: $pageUrl = preg_replace("&type=main", "", $pageURL); But it still returns the full url including type=main. How can I get rid of that from the url?

• Yet another C# Deadlock Debugging Question

  - by Roo

  Hi All, I have a multi-threaded application build in C# using VS2010 Professional. It's quite a large application and we've experienced the classing GUI cross-threading and deadlock issues before, but in the past month we've noticed the appears to lock up when left idle for around 20-30 minutes. The application is irresponsive and although it will repaint itself when other windows are dragged in front of the application and over it, the GUI still appears to be locked... interstingly (unlike if the GUI thread is being used for a considerable amount of time) the Close, Maximise and minimise buttons are also irresponsive and when clicked the little (Not Responding...) text is not displayed in the title of the application i.e. Windows still seems to think it's running fine. If I break/pause the application using the debugger, and view the threads that are running. There are 3 threads of our managed code that are running, and a few other worker threads whom the source code cannot be displayed for. The 3 threads that run are: The main/GUI thread A thread that loops indefinitely A thread that loops indefinitely If I step into threads 2 and 3, they appear to be looping correctly. They do not share locks (even with the main GUI thread) and they are not using the GUI thread at all. When stepping into the main/GUI thread however, it's broken on Application.Run... This problem screams deadlock to me, but what I don't understand is if it's deadlock, why can't I see the line of code the main/GUI thread is hanging on? Any help will be greatly appreciated! Let me know if you need more information... Cheers, Roo -----------------------------------------------------SOLUTION-------------------------------------------------- Okay, so the problem is now solved. Thanks to everyone for their suggestions! Much appreciated! I've marked the answer that solved my initial problem of determining where on the main/UI thread the application hangs (I handn't turned off the "Enable Just My Code" option). The overall issue I was experiencing was indeed Deadlock, however. After obtaining the call-stack and popping the top half of it into Google I came across this which explains exactly what I was experiencing... http://timl.net/ This references a lovely guide to debugging the issue... http://www.aaronlerch.com/blog/2008/12/15/debugging-ui/ This identified a control I was constructing off the GUI thread. I did know this, however, and was marshalling calls correctly, but what I didn't realise was that behind the scenes this Control was subscribing to an event or set of events that are triggered when e.g. a Windows session is unlocked or the screensaver exits. These calls are always made on the main/UI thread and were blocking when it saw the call was made on the incorrect thread. Kim explains in more detail here... http://krgreenlee.blogspot.com/2007/09/onuserpreferencechanged-hang.html In the end I found an alternative solution which did not require this Control off the main/UI thread. That appears to have solved the problem and the application no longer hangs. I hope this helps anyone who's confronted by a similar problem. Thanks again to everyone on here who helped! (and indirectly, the delightful bloggers I've referenced above!) Roo -----------------------------------------------------SOLUTION II-------------------------------------------------- Aren't threading issues delightful...you think you've solved it, and a month down the line it pops back up again. I still believe the solution above resolved an issue that would cause simillar behaviour, but we encountered the problem again. As we spent a while debugging this, I thought I'd update this question with our (hopefully) final solution: The problem appears to have been a bug in the Infragistics components in the WinForms 2010.1 release (no hot fixes). We had been running from around the time the freeze issue appeared (but had also added a bunch of other stuff too). After upgrading to WinForms 2010.3, we've yet to reproduce the issue (deja vu). See my question here for a bit more information: 'http://stackoverflow.com/questions/4077822/net-4-0-and-the-dreaded-onuserpreferencechanged-hang'. Hans has given a nice summary of the general issue. I hope this adds a little to the suggestions/information surrounding the nutorious OnUserPreferenceChanged Hang (or whatever you'd like to call it). Cheers, Roo

• .htaccess redirect umlaut domain

  - by Christian Engel

  I am trying to redirect requests from a umlaut domain to another domain. My following code works with ANY other domain, but not umlaut: <IfModule mod_rewrite.c> RewriteCond %{HTTPS} !=on RewriteCond %{HTTP_HOST} ^(www\.)?frankfurter-flöhe\.de/$ [NC] RewriteRule ^ http://kinderkultur-frankfurt.de/frankfurter-floehe-theaterprogramm.html [R=301,L] </IfModule> However, when I call the umlaut domain and copy it from google chromes address bar after that, I get this: http://xn--frankfurter-flhe-zwb.de/ Altough, if I use that obfruscated domain in my htaccess instead of the "real" umlaut domain, it doesn't work either. Does anybody have an idea how to match that domain?

• WordPress front page (homepage) fails to redirect when static front page is set.

  - by Keyslinger

  I have configured WordPress to display a static front page as described here: http://codex.wordpress.org/Settings_Reading_SubPanel#Reading_Settings When save changes and try to visit my front page, my browser displays the following error: "The page isn't redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete." Disabling cookies does not remedy the situation. I'm using the theme, Constructor (http://wordpress.org/extend/themes/constructor), which I suspect may be contributing to the problem. How can I make WordPress properly display my front page?

• How to provide Input to Dialogs designed by Qt Designer

  - by GG

  Hello, I am a Qt beginner and working with Qt Designer to develop some small UI elements.

I am introducing bookmark feature which somewhat look like http://img293.imageshack.us/img293/3041/screenshotyb.png. Now the problem I am facing is How can I show all existing bookmark folders in the drop down(say folders are in a QVector). So my main problem is how can I pass some inputs to the UI element. I think I'm clear, please let me know if further explanation is required. Sorry for adding links directly, rich formatting in my browser is not working. Thanks in advance,

• Is there a way to programmatically extract the feed of a podcast from the iTunes page?

  - by J. Pablo Fernández

  From an iTunes page, like http://itunes.apple.com/us/podcast/this-week-in-tech-mp3-edition/id73329404, is there a way to extract the corresponding feed address? In this case it would be http://leoville.tv/podcasts/twit.xml. I know that if you open on iTunes you can extract it manually, but I want to do it programmatically. There's a link to the website of the podcast, but it may not be accurate. In this case it points to a web site with 20 podcasts on it.

• HTTPS and FormAssembly

  - by Mark

  We are using a FormAssembly page to collect feedback - it's hosted within an IFrame on the side of our site's master page. The thing is, that some parts of our site are HTTPS - viewing and posting the form is ok in HTTPS, but the problem comes with the "thank you" page - we are using the configurable custom thank you page (configured within FormAssembly iteself). Is there are way we can send the desired response page up (perhaps via a hidden field within the posted form?) - this way we can send the HTTPS link for the HTTPS version of the form and the normal HTTP link for the HTTP form? Thanks!

• Determine calling executable in Python

  - by Brian Rosner

  I am trying to find the best way of re-invoking a Python script within itself. Currently it is working like http://github.com/benoitc/gunicorn/blob/master/gunicorn/arbiter.py#L285. The START_CTX is created at http://github.com/benoitc/gunicorn/blob/master/gunicorn/arbiter.py#L82-86. The code is relying on sys.argv[0] as the "caller". However, this fails in cases where it is invoked with: python script.py ... This case does work: python ./script.py ... because the code uses os.chdir before running os.execlp. I did notice os.environ["_"], but I am not sure how reliable that would be. Another possible case is to check if sys.argv[0] is not on PATH and is not executable and use sys.executable when calling os.execlp. Any thoughts on a better approach solving this issue?

• Java regex replace multiple file paths in a large String

  - by Joe Goble

  So a Regex pro I am not, and I'm looking for a good way to do this. I have a large string which contains a variable number <img> tags. I need to change the path on all of these images to images/. The large string also contains other stuff not just these img's. <img src='http://server.com/stuff1/img1.jpg' /> <img src='http://server.com/stuff2/img2.png' /> Replacing the server name with a ReplaceAll() I could do, it's the variable path in the middle I'm clueless on how to include. It doesn't necessarily need to be a regex, but looping through the entire string just seems wasteful.

• OpenID token from Google (using www)?

  - by MunkiPhD

  I've come across the following situation when using OpenID and Google as the authenticator. If you type siteName.com it takes you to http://sitename.com Which returns a different token than if I were to login to www.siteName.com, which would take me to http://www.siteName.com As a result, Google returns a different authentication token. Is there a simple fix around this? Maybe redirect the user from siteName.com to www.siteName.com? Would this be a server issue, or is this something I can do programmatically? Thanks in advance for any answers, this question had plagued me for some time now as I just figured out why others had been receiving different credentials upon logging in.

• Dual-line bilingual paragraph in LaTeX

  - by D W

  An interlinear gloss can be used to layout a translation of a document. http://en.wikipedia.org/wiki/Interlinear_gloss Usually this is done word-by-word or morpheme-by-morpheme. However, I would like to do this in a different way, translating entire paragraphs at a time. http://www.optimnem.co.uk/learning/spanish/three-little-pigs.php For now I am not interested in taking into account the order of words or phrases that change order between languages. That is, I don't mind if the words in the paragraph are not aligned or if the length of one paragraph is much longer than the other, causing an overhanging line. As far as I can tell, the following packages do not meet my needs: covingtn.sty cgloss4e.sty gb4e.sty lingmacros.sty - shortex

• What are the typical reasons Javascript developed on Firefox fails on IE?

  - by karlthorwald

  I developed some javascript enhanced pages that run fine on recent Firefox and Safari. I missed to check in Internet Explorer, and now I find the pages don't work on IE 6 and 7 (so far). The scripts are somehow not executed, the pages show as if javascript wasn't there, although some javascript is executed. I am using own libraries with dom manipulation, from YUI 2 I use YUI-Loader and the XML-Http-Request, and on one page I use "psupload", which depends on JQuery. I am installing Microsoft Script Editor from Office XP and will now debug. I will also write specific tests now. What are the typical failing points of IE? What direction I can keep my eyes open. I found this page, which shows some differences: http://www.quirksmode.org/compatibility.html Can you from your experience name some typical things I should look for first? I will also ask more questions here for specific tasks later, but for now I am interested in your experience why IE usually fails on scripts that run fine in Firefox

• Chrome Extension Manifest 'Matches'

  - by Aristotle

  I'm trying my hands at a simple Chrome Extension, but am running into a problem with providing a value for the matches array in my content_scripts. { "name": "My Extension", "version": "1.0", "description": "My Extension Experiment", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "default_popup": "popup.html" }, "content_scripts": { "matches": ["http://*"], "js": ["scripts.js"] } } When I try to load this extension into Chrome, I get the following message: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.Invalid value for 'content_scripts'. I cannot see what is "invalid" about my value though. What I'm trying to do is match every URL, so my extension can manipulate the DOM (via javascript within scripts.js) of any page it is ran on. Am I missing something, going about this all wrong, or what? update After posting this question, I did notice that the Google example was slightly different than mine, so I modified my code a bit to reflect their syntax: "content_scripts": [{ "matches": ["http://*"], "js": ["scripts.js"] }] That being said, I still get the following error when trying to load my extension: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'. Invalid value for 'content_scripts[0].matches[0]'.
