  • Google Chrome Application Mode: Possible to isolate multiple instances?

    - by Jonathan Eunice
    I want to run multiple Google Chrome application windows logged into the same web site (Twitter.com, say), each with different credentials. Is this possible? If so, how? My initial testing shows that multiple Chrome app windows are not sufficiently isolated to do this. Logging into the second account logs me into the second account in both windows, suggesting that they are sharing information just as two Chrome tabs might.

  • Whats the best method for queuing time-sensitive messages with PHP/MySQL?

    - by Mike Diena
    I'm building an SMS call and response system in a new app that receives a message via an aggregator gateway, checks it for functional keywords (run, stop, ask, etc), then processes it appropriately (save to the database, return an answer, or execute a task based on the users authorization). It's running fine at the moment as there are only a few users, but I figure its going to have more issues as we scale it up. We're currently running it on a single DV machine (mediatemple base dv). My question is this: does it make more sense to set something up like Memcached to run a queue, or a simple database with a daemon running to process each message one by one? I don't have much experience with either, so any advice would be helpful. Since the messaging is somewhat time-sensitive, what would be the fastest and most reliable way to handle this? Also, since we're sending responses, I'll probably need to set up and outbound message queue as well. Would it make sense to use the same concept for both?

  • Flash Camera Permissions Dialog: Why does it sometimes take more than one click to work?

    - by Emmett Shear
    Often, but not always, the first few clicks on the "Allow" button on the Flash camera permissions dialog are ignored. This is very frustrating for users. And for me, when I'm testing code! I'm afraid I don't really know what else to say about the problem to give more insight. My hunch is that it has something to do with getting focus on the embed element, but that is merely a guess. See Justin.tv for an example.

  • applying css to dijit button

    - by peirix
    I have the following HTML and CSS: <button id="myBtn" dojoType="dijit.form.Button">Testing</button> #myBtn { margin-left: 100px; } The CSS is supposed to push the button in 100px. But since dijit applies some extra layers of HTML around the button, the button gets a 100px padding. JSbin to show the problem edit: Found one (not IE6-compatible) solution: [widgetid=myBtn] { margin-left: 100px; }

  • Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML

    - by phpwns
    Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML tables) generated with Javascript? An embarrassingly simple, though workable solution using Crowbar: <?php function get_html($url) // $url must be urlencode(d) { $context = stream_context_create(array( 'http' => array('timeout' => 120) // HTTP timeout in seconds )); $html = substr(file_get_contents('http://127.0.0.1:10000/?url=' . $url . '&delay=3000&view=browser', 0, $context), 730, -32); // substr removes HTML from the Crowbar web service, returning only the $url HTML return $html; } ?> The advantage to using Crowbar is that the tables will be rendered (and accessible) thanks to the headless mozilla-based browser. The problem, of course, is being dependent on on an external web service, especially given that SIMILE seems to undergo regular server maintenance. :( A pure php solution would be nice, but any functional (and reliable) alternatives would be great.

  • Wordpress duplicate comment detection

    - by codecowboy
    Hi, Does anyone know how to disable duplicate comment detection in Wordpress (2.9.2)? I'm looking for a way to do this programatically without editing core files. We're adding comments via XMLRPC and the duplicate detection in wp-includes/comment.php (line 494) is causing issues during testing. Thanks!

  • Validating key/certificate pairs with M2Crypto when a certificate chain is needed

    - by Charles Duffy
    M2Crypto.X509.X509 objects have a verify(pkey) method, which provide a means of testing that a given certificate does in fact sign a specified key. This is a good and useful thing -- except that sometimes the certificate I want to verify in this way is invalid without the use of an intermediate certificate, which this API does not appear to allow a way to specify. Is there an alternate means of validating a certificate / private key pair which will work even when the certificate is unable to stand alone?

  • Strategy for developing a multi function asp.net web application

    - by user247023
    I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?

  • Problem: connecting to drupal on hostgator without pointed domain.

    - by Kirk
    I need to connect to drupal on a website that I'm programming on a hostgator account. The website that I'm working on currently receives a lot of traffic, and I would like to make sure that it is fully functional before I launch the new website. The old website was programmed with .asp which hostgator doesn't support, and the old webhost doesn't support drupal or .php which are integral to the new web design. Drupal 6 has been freshly installed on my website, but when I try to login, it redirects me to http://gator83.hostgator.com/?q=node&destination=node instead of the drupal control panel. Is it possible to work around this? Thank you in advance.

  • Scala Tuple Deconstruction

    - by dbyrne
    I am new to Scala, and ran across a small hiccup that has been annoying me. Initializing two vars in parallel works great: var (x,y) = (1,2) However I can't find a way to assign new values in parallel: (x,y) = (x+y,y-x) //invalid syntax I end up writing something like this: val xtmp = x+y; y = x-y; x = xtmp I realize writing functional code is one way of avoiding this, but there are certain situations where vars just make more sense. I have two questions: 1) Is there a better way of doing this? Am I missing something? 2) What is the reason for not allowing true parallel assignment?

  • Best protocol for client/server communication, from PHP/Perl to C++/Qt4

    - by Kyle
    I'm the author of an Open Source kiosk management system, Libki. The current version, though functional, was very much a learning experience for me. I'm working on a complete rewrite and am having a hard time deciding what protocol to use. The server will be written in PHP or Perl. Most likely PHP because I need to support some uncommon protocols that Library software use, ( SIP and NCIP ). So far I've only found a SIP2 library in PHP. The client is written in C++/Qt4. I'm looking at RPC and REST for client/server communication. I've found RPC client libraries for Qt4, and REST is already part of the Qt4 libraries. Is there an alternative I've missed? So far, REST seems to be the winner.

  • How to hack your own website

    - by Saif Bechan
    I am in late testing phase of my web application. The application will be tested at a larger scale now. During this time I want to try and hack my own system and application with some tools, scripts, etc. Mostly some code I can try and execute in the browser. I have backups for the whole system so even down to the kernel can be hacked. My system is nginx,apache,php,mysql on Linux CentOS.

  • C# equivalent of NaN or IsNumeric

    - by johnc
    This seems like a fairly simple question, and I'm surprised not to have required it before. What is the most efficient way of testing a string input is a numeric (or conversely Not A Number). I guess I can do a Double.Parse or a regex (see below) public static bool IsNumeric(this string value) { return Regex.IsMatch(value, "^\\d+$"); } but I was wondering if there was a implemented way to do it, such as javascript's NaN() or IsNumeric() (was that VB, I can't remember).

  • Cheapest way of binding local variable to closure

    - by mmotorny
    I believe following to be a cheapest way of binding local variable to closure: void ByRValueReference(A&& a) { } std::function<void ()> CreateClosureByRValueReference() { A a; std::function<void ()> f = std::bind(&ByRValueReference, std::move(a)); // !!! return f; } However, it does not compile under Clang 3.1: error: no viable conversion from '__bind<void (*)(A &&), A>' to 'std::function<void ()>' and gcc 4.6.1: /usr/include/c++/4.6/functional:1778:2: error: no match for call to ‘(std::_Bind<void (*(A))(A&&)>) ()’ Am I violating the standard or it's just broken standard libraries?

  • wpf Image resources and visual studio 2010 resource editor

    - by Berryl
    Hello My motivation for this question is really just to specify an image to be used in a user control via a dependency property for ImageSource. I'm hitting some pain points involving the management, access, and unit testing for this. Is the resource editor a good tool to use to maintain images for the application? What is the best way to translate the Bitmap from the editor to an ImageSource? How can I grab the resource Filename from the editor? Cheers, Berryl

  • Memory Allocation increases in didSelectRowAtIndexPath

    - by mongeta
    Hello, I'm testing my App and in a very simple view, each time a tap on a UITableView row, my allocation overall bytes get higher and higher and never go downs. I don't have any special code there, so I created a new project from scratch with a very simple view, force one section and just three rows. In the didSelectRowAtIndexPath code do nothing, and fire it with instruments and memory allocation and, the memory goes up with every cell selection ... Is this normal behaviour ? thanks, regards, m.

  • How do you write an idiomatic Scala Quicksort function?

    - by Don Mackenzie
    I recently answered a question with an attempt at writing a quicksort function in scala, I'd seen something like the code below written somewhere. def qsort(l: List[Int]): List[Int] = { l match { case Nil => Nil case pivot::tail => qsort(tail.filter(_ < pivot)) ::: pivot :: qsort(tail.filter(_ >= pivot)) } } My answer received some constructive criticism pointing out that List was a poor choice of collection for quicksort and secondly that the above wasn't tail recursive. I tried to re-write the above in a tail recursive manner but didn't have much luck. Is it possible to write a tail recursive quicksort? or, if not, how can it be done in a functional style? Also what can be done to maximise the efficiency of the implementation? Thanks in advance.
