  • Creating an image from webcam every x miliseconds

    - by Rita
    Hello everyone, I am using c# to integrate with a web cam. I need to generate a snapshot image every x miliseconds and save it to file. I already have the code up and running to save to file on a button click event, however I wonder what am I supposed to do when taking snapshots in the background - Should this be multi threaded? I'm honestly not sure. I could just block the UI thread, put Thread.Sleep and then just take the snapshot, but I don't know if this is right. I thought of using a background worker, but I am now experiencing cross threaded difficulties with SendMessage... So I wonder if I should even go and bother to multi-thread or just block the UI. Help greatly appertained, thanks in advance.

  • Gtk+ vs Qt language bindings

    - by Adam Smith
    Put shortly: For those familiar with language bindings in Qt and Gtk+. E.g. python and ruby. Are there any quality or capability difference? More background: I know C++ and Qt very well. Minimal experience with Gtk+. I know C++ is not ideal for language bindings due to the lack of a well defined ABI (application binary interface). I also read that Gtk+ was designed to be bound to other languages. So I wonder how this manifets itself in practice. Are the Gtk+ bindings better maintained or work better in some way than their Qt counterparts? I am presently quite interested in the Go language, and they have started developing Gtk+ bindings. However C++ bindings is far away. It makes me wonder whether learning Gtk+ is worth it.

  • Hierarchical Data in MySQL is fast to retrieve?

    - by ajsie
    i've got a list of all countries - states - cities (- subcities/villages etc) in a XML file and to retrieve for example a state's all cities it's really quick with XML (using xml parser). i wonder, if i put all this information in mysql, is retrieving a state's all cities as fast as with XML? cause XML is designed to store hierarchical data while relational databases like mysql are not. the list contains like 500 000 entities. so i wonder if its as fast as XML using either of: Adjacency list model Nested Set model And which one should i use? Cause (theoretically) there could be unlimited levels under a state. And which is fastest for this huge dataset? Thanks!

  • How simplify iPhone localization?

    - by mamcx
    I need to localiza a in development app for English & Spanish. Despite the fact I follow the Apple way of use NSLocalizedString & create nibs for both, I already lost the track of the new string that need to get localized and found with surprise that I need to redo the nibs in spanish when I change the master. (Just like this http://www.gigliwood.com/weblog/Cocoa/A_Great_Need_for_Be.html) I wonder if exist a better/alternative/more automated way. I know the use of gettext & poedit and wonder if something like that can be used. Or if exist some script or tool for this.

  • Does C++11 offer a better way to concatenate strings on the fly?

    - by Lohoris
    I've seen this answer, and I wonder (I hope) if C++11 has come up with a native better method to concatenate, and possibly format, strings. With "better" I mean actually really one-line, like in pretty much all higher level languages (bonus points if it supports something like python's "formatted string"%(tuple) syntax but I guess that's really hoping for too much). The ideal result should be something like: my_func("bla bla bla" << int(my_int) << "bla bla bla"); The only barely acceptable methods listed in that answer are the fastformat ones, but I wonder if C++11 managed to do better.

  • How to monitor MySQL query errors, timeouts and logon attempts?

    - by Abel
    While setting up a third party closed source CMS (Sitefinity) the setup doesn't create all tables and procedures necessary to run it. The software lacks a logging system itself and it made me wonder: could I trace and monitor failing SQL statements from MySQL? This serves more than only the purpose of solving my issue with Sitefinity. More often I wonder what's send to the MySQL server, not wanting to dive into the software products or setup a debugging environment etc. I tried JetProfiler (only performance) and looked through a few others, but although they monitor a lot, they don't monitor query failures, timeouts or logon attempts. Does anyone know a profiler, tracer, monitoring tool, commercial or free, that can show me this information?

  • Complex nib is slow to load

    - by Dan Ray
    I'm looking for advice about a nib that's very slow to load. It's big and complex, with lots of subviews and doodads. When I fire my UINavController to push it, it's noticeably laggy (maybe almost a second) on my 3G. It sits there with the table cell selected and nothing else happening for long enough to make you wonder if it's broken. I wonder about pre-loading it in another thread while the user is on the previous view. I could probably fire the selector in the background with a delay in the previous view's viewDidAppear, and then keep it in a property until push time comes. Thoughts?

  • PHP: read all files but randomly?

    - by mathiregister
    hi there, i wonder if there's a way of reading a directory in a random order. With the following code i'm running through the directory thumbs and it's printing images on my website. However, they are always read alphabetically and i wonder if there's a way in doing this randomly? <?php $path = 'thumbs'; if ($handle = opendir($path)) { while (false !== ($file = readdir($handle))) { if ($file != '.' && $file != '..' && $file != '.DS_Store' && $file != 'Thumbs.db') { print "<img class='thumb' src='$path/$file'/>"; } else { //no proper file } } closedir($handle); } ?> thank you for your suggestions! regards
