  • Proper attribution of derived work in a GPL project

    - by Anton Gogolev
    This is a continuation of me rewriting GPL project. What will be the correct way of attributing my project as being a derivative of some other GPL-licensed project? So far I came up with: HgSharp Original Copyright Matt Mackall <[email protected]> and contributors. The following code is a derivative work of the code from the Mercurial project, which is licensed GPLv2. This code therefore is also licensed under the terms of the GNU Public License, verison 2. For information on the license of this code when distributed with and used in conjunction with the other modules in the HgSharp project, please see the root-level COPYING file.

  • Linux terminal - frozen update of input but can execute commands?

    - by Torxed
    How do i restart a shell session from within SSH when it looks something like this: anton@ubuntu:~$ c: command not found anton@ubuntu:~$ lib anton@ubuntu:~$ this is working, but its messed up anton@ubuntu:~$ I can execute commands, but as i input them nothing shows on the console, but as soon as i press enter the command executes and the output comes (without line-endings, as shown above) exec bash bash --login clear nothing really works, restarting the SSH session however works. Temporary solution is to start a screen session and every time the interface freezes you simply do Ctrl+a-c to start a new session and close the old one..

  • Simplified knapsack in PHP

    - by Mikhail
    I have two instances where I'd like to display information in a "justified" alignment - but I don't care if the values are switched in order. One example being displaying the usernames of people online: Anton Brother68 Commissar Dougheater Elflord Foobar Goop Hoo Iee Joo Rearranging them we could get exactly 22 characters long on each line: Anton Brother68 Foobar Commissar Elflord Goop Dougheater Hoo Iee Joo This is kind of a knapsack, except seems like there ought to be a P solution since I don't care about perfection, and I have multiple lines. Second instance is identical, except instead of names and character count I would be displaying random images and use their width.

  • DirectSound affects system volume on WinXP

    - by Anton
    Hello guys, I'm currently developing an audio engine that is used in voice network chat software. Everything is working fine - capture/playback/mixing channels. The problem is in using it under Windows XP. I've been getting user reports with information that their global system volume is set to zero after launching the application. I'm assuming that happens because of WaveOut/DSound conflict. How can I force DSound not to affect system volume? Playback device is initialized: DirectSoundCreate8(&GUID, &pAudio, NULL); and: pAudio-SetCooperativeLevel(parentWnd, DSSCL_PRIORITY); I'm currently not able to debug the application, cause I'm using Vista and everything is OK. Hope you can help me with this issue! Thanks a Lot! Regards, Anton.

  • How does Qt implement signals and slots?

    - by anton
    Can someone explain to me the basic idea of Qt signals&slots mechanism IMPLEMENTATION? I want to know what all those Q_OBJECT macros do "in plain C++". This question is NOT about signals&slots usage. added: I know that Qt uses moc compiler to transform Qt-C++ in plain C++. But what does moc do? I tried to read "moc_filename.cpp" files but I have no idea what can something like this mean void *Widget::qt_metacast(const char *_clname) { if (!_clname) return 0; if (!strcmp(_clname, qt_meta_stringdata_Widget)) return static_cast<void*>(const_cast< Widget*>(this)); return QDialog::qt_metacast(_clname); } Thanks in Advance, anton

  • Third-party open-source projects in .NET and Ruby and NIH syndrome

    - by Anton Gogolev
    The title might seem to be inflammatory, but it's here to catch your eye after all. I'm a professional .NET developer, but I try to follow other platforms as well. With Ruby being all hyped up (mostly due to Rails, I guess) I cannot help but compare the situation in open-source projects in Ruby and .NET. What I personally find interesting is that .NET developers are for the most part severely suffering from the NIH syndrome and are very hesitant to use someone else's code in pretty much any shape or form. Comparing it with Ruby, I see a striking difference. Folks out there have gems literally for every little piece of functionality imaginable. New projects are popping out left and right and generally are heartily welcomed. On the .NET side we have CodePlex which I personally find to be a place where abandoned projects grow old and eventually get abandoned. Now, there certainly are several well-known and maintained projects, but the number of those pales in comparison with that of Ruby. Granted, NIH on the .NET devs part comes mostly from the fact that there are very few quality .NET projects out there, let alone projects that solve their specific needs, but even if there is such a project, it's often frowned upon and is reinvented in-house. So my question is multi-fold: Do you find my observations anywhere near being correct? If so, what are your thoughts on quality and quantitiy of OSS projects in .NET? Again, if you do agree with my thoughts on "NIH in .NET", what do you think is causing it? And finally, is it Ruby's feature set & community standpoint (dynamic language, strong focus on testing) that allows for such easy integration of third-party code?

  • How to track events or e-commerce sales that occur later using Google Analytics?

    - by Anton
    Here's my problem: I have a static site with Google Analytics tracking code. To buy one of my services, users call me, and when their order is ready (many days later), I send them an e-mail link to a special page (download.php) where I have GA tracking code that is executed the first time they visit, so I track a "sale". The issue is, GA thinks that "sale" was a separate visit, and erroneously shows that only direct visits to my site result in sales. I don't understand how I can view stats (Pages / Visit, Avg. Time on Site, etc.) about users who eventually bought something. I've tried events and e-commerce tracking with no luck. Please help!

  • Character progression through leveling, skills or items?

    - by Anton
    I'm working on a design for an RPG game, and I'm having some doubts about the skill and level system. I'm going for a more casual, explorative gaming experience and so thought about lowering the game complexity by simplifying character progression. But I'm having trouble deciding between the following: Progression through leveling, no complex skill progression, leveling increases base stats. Progression through skills, no leveling or base stat changes, skills progress through usage. Progression through items, more focus on stat-changing items, items confer skills, no leveling. However, I'm uncertain what the effects on gameplay might be in the end. So, my question is this: What would be the effects of choosing one of the above alternatives over the others? (Particularly with regards to the style and feel of the gameplay) My take on it is that the first sacrifices more frequent rewards and customization in favor of a simpler gameplay; the second sacrifices explicit customization and player control in favor of more frequent rewards and a somewhat simpler gameplay; while the third sacrifices inventory simplicity and a player metric in favor of player control, customization and progression simplicity. Addendum: I'm not really limiting myself to the above three, they are just the ones I liked most and am primarily interested in.

  • Is it worth being computer languages polyglot?

    - by Anton Barkowski
    You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn all relatively known programming languages. And here is question itself: Will being programming languages polyglot actually help you (And I don't mean usual "Programmer should know at least all paradigms", I mean really all languages you usually hear about)? Does anybody have similar experience? Does it help with job/skills/career? How often are you able to apply those skills?

  • Rewrote GNU GPL v2 code in another language: can I change a license?

    - by Anton Gogolev
    I rewrote some parts of Mercurial (which is licensed under GNU GPL v2) in C#. Naturally, I looked a lot into original Python code and some parts are direct translations from Python to C#. Is is possible have "my code" licensed under different terms or to even make a part of a closed-source commercial application? If not, can I re-license "my-code" under LGPL, open-source it and then use this open-sourced C# library in my closed-source commercial application?

  • How are realistic 3D faces created and animated in video games?

    - by Anton
    I'm interested in being able to create realistic faces and facial expressions for the 3D characters of a game I'm working on. Think something similar to the dialog scenes in games like Mass Effect. Unfortunately I'm not sure where to begin. I'm sure the faces/animations are created through 3D Modeling software, but otherwise I am lost. Do facial animations use the same "bones" that normal body animation uses? Is there any preferred 3D software for realistic faces and animations? Is there a preferred format to export these faces and animations in?

  • Emacs/Vim/Vi - do they have a place in modern software development ecosystem? [closed]

    - by Anton Gogolev
    Watching all those screencasts (and listening all those podcasts) with more-or-less famous hackers/programmers I hear that many of those use emacs/vi(m) for their daily work. Now, I myself tried using both emacs and vim, and I honestly cannot understand why would anybody use these for any kind of serious development. The most advertised feature is something along the lines of "you'll be able to work with text (meaning cutting, pasting, duplicating, moving, etc) up to ten times faster than with conventional IDEs", but I don't buy that. When has the success of a software project been defined by how fast a programmer can juggle lines in a text editor or by saving a couple of keystrokes here and there? Plugins and extensions? I bet nothing comes close to R# or IDEA in terms of refactoring support ("Rename" refactoring implemented by means of "Search and Replace" is not a refactoring IMO); others are trivial. Ubiquitous and available everywhere? So what? How often do you find yourself editing files over a 300 baud connection on an esoteric *nix installation without a VCS? So here goes: do said editors have a justified place in a modern software development ecosystem?

  • Why does my CD Tray keep popping open?

    - by Anton
    I have Ubuntu server - Ubuntu 10.04.3 LTS and I can't figure out why my CD tray is opening all the time. I have looked into /var/log/auth.log, cron list and found nothing. The eject command closes tray and then it gets opened again. The server has a LAMP (Linux-Apache-MySQL-PHP) setup and I can't afford to restart it now. How can I find out who or which program is popping the tray open? Which programs can cause this behavior?

  • Double pointer const-correctness warnings in C

    - by Michael Koval
    You can obviously cast a pointer to non-const data to a a pointer of the same type to const data: int *x = NULL; int const *y = x; Adding additional const qualifiers to match the additional indirection should logically work the same way: int * *x = NULL; int *const *y = x; /* okay */ int const *const *z = y; /* warning */ Compiling this with GCC or Clang with the -Wall flag, however, results in the following warning: test.c:4:23: warning: initializing 'int const *const *' with an expression of type 'int *const *' discards qualifiers in nested pointer types int const *const *z = y; /* warning */ ^ ~ Why does adding an additional const qualifier "discard qualifiers in nested pointer types"?

  • jQuery UI dialog + WebKit + HTML response with script

    - by Anthony Koval'
    Once again I am faced with a great problem! :) So, here is the stuff: on the client side, I have a link. By clicking on it, jQuery makes a request to the server, gets response as HTML content, then popups UI dialog with that content. Here is the code of the request-function: function preview(){ $.ajax({ url: "/api/builder/", type: "post", //dataType: "html", data: {"script_tpl": $("#widget_code").text(), "widgets": $.toJSON(mwidgets), "widx": "0"}, success: function(data){ //console.log(data) $("#previewArea").dialog({ bgiframe: true, autoOpen: false, height: 600, width: 600, modal: true, buttons: { "Cancel": function() { $(this).dialog('destroy'); } } }); //console.log(data.toString()); $('#previewArea').attr("innerHTML", data.toString()); $("#previewArea").dialog("open"); }, error: function(){ console.log("shit happens"); } }) } The response (data) is: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript">var smakly_widget_sid = 0 ,widgets = [{"cols": "2","rows": "2","div_id": "smakly_widget","wid": "0","smakly_style": "small_image",}, ] </script> <script type="text/javascript" src="/media/js/smak/smakme.js"></script> </head> <body> preview <div id="smakly_widget" style="width:560px;height:550px"> </div> </body> </html> As you see, there is a script to load: smakme.js, somehow it doesn't execute in WebKit-based browsers (I tried in Safari and Chrome), but in Firefox, Internet Explorer and Opera it works as expected! Here is that script: String.prototype.format = function(){ var pattern = /\{\d+\}/g; var args = arguments; return this.replace(pattern, function(capture){ return args[capture.match(/\d+/)]; }); } var turl = "/widget" var widgetCtrl = new(function(){ this.render_widget = function (w, content){ $("#" + w.div_id).append(content); } this.build_widgets = function(){ for (var widx in widgets){ var w = widgets[widx], iurl = '{0}?sid={1}&wid={2}&w={3}&h={4}&referer=http://ya.ru&thrash={5}'.format( turl, smakly_widget_sid, w.wid, w.cols, w.rows, Math.floor(Math.random()*1000).toString()), content = $('<iframe src="{0}" width="100%" height="100%"></iframe>'.format(iurl)); this.render_widget(w, content); } } }) $(document).ready(function(){ widgetCtrl.build_widgets(); }) Is that some security issue, or anything else?

  • django test client trouble

If I get the data from the server with standard urllib2.urllopen().read() it works in the proper way. Any ideas how I can solve this case?
