  • Wow. Sweet @ss WebGL Demo

    Here is a write up of a very nice WebGL demo I thought might interest some of you. Personally I am quite impressed what Stavros (the orginal author) has created, including his GUI interface/widgets and debugging toolkit.

  • Announcing Xamarin 2.0

    @Harlequin: I consider VS to be a free tool given all the Spark programs MS offers; WebsiteSpark, DreamSpark, BizSpark, and YouthSpark.

  • Announcing Xamarin 2.0

    Today Xamarin announced version 2.0 of their tools for using C# and Mono to develop iOS/Android apps on Windows/Mac/Linux with Visual Studio/Xamarin Studio.

    Xamarin also announced new free and individual developer versions.

    Part of the sales pitch Xamarin offered in the past is the easy of use and much simplified code reduction their C# libraries provide above and beyond Objective-C and Java. This new version much improves their tooling, according to Xamarin.

    My question to everyone here is, have you tried using C# or the Xamarin products to develop mobile applications for iPhone or Android? If so, what was your experience, and if not what has kept you from trying and using Xamarin mobile development tools?

    I'll answer first: No I haven't tried Xamarin studio previously because their lowest price was $999 and I have a strong bias against paid developer tools having had experienced Borland Delphi.

  • Does anyone know how this can be done on Windows?

    I want to write a program which allows users to play sound clips into their microphone (recording device) so that they can mix in clips with their voice while using VOIP software (Ventrillo or Skype for example) from their PC. When I say play sound clips into their microphone, I mean the user presses a button, and the sound clip is played that both the user and the people on the other end of the VOIP connection can hear. What API functions can be used to do this on Windows?

  • Silverlight, another nail in its coffin

    , Ian2 wrote

    The new WinRT stuff is just Silverlight by another name, and closer to the metal to boot. 

    IMO it is just politics that it isn't called "Silverlight.RT" or some such.

    Except WinRT apps don't work in a variety of browsers they only work on Windows 8, they cannot run along with the desktop, require submission and approval from Microsoft to run, and Microsoft takes 30% of any money generated from your app.

    And as far a "closer to the metal" goes, you're the first person I've heard describe Windows 8 Metro apps as "closer to the metal".

  • Silverlight, another nail in its coffin

    In the past I invested time in learning how to develop with Silverlight. I stopped when it became clear  MS was going to scrap it. They pulled The Gu away from it, Jesse the Silverlight Geek stopped working for Microsoft, and it seemed like Ballmer's "Developer's, developer's, developer's" rant was just more lip service. Microsoft develops something, promotes it to developers, then walks away and pushes the next something to replace the last something; leaving the many who invest time, effort, and money chasing Microsoft technology royally screwed.

    Microsoft killed off Silverlight.net this week. The Silverlight gallery is gone along with the Silverlight blogs, and 90% of the video training series as Microsoft prepares to kill off Siverlight.

    From the comments:

    The biggest mistake Microsoft made was to stop developing VB6. Everything after that has been a failure.

    I agree that Microsoft stopping development of VB6 was a huge mistake.

  • Hobby electronics programming

    Has anyone here done any hobby work with electronics and micro controllers? I was wondering how hard it would be to program appliances like this ice cream maker.

    I figure the computer controlled part of that setup could be built using an arduino and one of the many cheap and small touch screen LCDs available today.

  • Interest in Microsoft Surface 2nd to Last

    Kids, the purveyors of what is cool and not-so-cool, ranked Microsoft Surface next to last in tech device interest, just ahead of Apple TV and behind any other mobile phone.


  • Do you have romnesia?

    @Bass: To animate all you do is repeatedly call setTimeout, then adjust styles based on an easing. A while back wrote a little easing browser for my own user defined easings (across multiple languages/platforms). Test page here.

    <script type="text/javascript">
    // a few example easings
    function linear(percent) { return percent; }
    function easy(percent) { return percent * percent * (3.0 - 2.0 * percent); }
    var negcospi = 1.61803398874989;
    function snap(percent) {
        percent = percent * percent;
        percent = (percent * 1.4) - 0.2;
        return 0.5 - Math.cos(Math.PI * percent) / negcospi;
    function time() {
      return new Date().getTime() / 1000;
    // the animate routine
    function animate(element, easing, duration, onanimate, ondone, start) {
      start = start == null ? time() : start;
      window.setTimeout(function() {
        var percent = (time() - start) / duration;
        var done = percent >= 1.0;
        if (done) {
            onanimate(element, 1.0);
            if (ondone) {
        } else {
            onanimate(element, easing(percent));
            animate(element, easing, duration, onanimate, ondone, start);
      }, 5);
    // our onanimate callback and a play function
    function move(element, percent) {
      element.style.left = 2000 * percent + "px";
    function play() {
      animate(document.getElementById("red"), snap, 2.0, move);
    <div id="red" style="background: red; position: relative; width: 100px; height: 100px;"></div>
    <button onclick="play()">Play</button>

  • Do you have romnesia?

    brought to you by the same man who was against gay marriage and the individual mandate before he was for them

    So you are upset that Obama wasn't for marriage equality sooner, is that your complaint? How does supporting Republicans, who traditionally attack gays, advance that cause?

    Obama said that raising the national debt by 4 trillion in 8 years was unpatriotic... but 5.5 trillion (so far) in less than 4

    I'm not sure where that attribution is sourced, but I thought you'd like to know that there was this market collapse brought on by the last Republican administration which wrecked our economy. I know a lot of morons worship the altar of free market economics, but that's not how the world works. People with money and power game the system to recursively extend their control, and the Republicans are the party that caters to the rich who want more money and power.

    and bravely took a stand against military engagements without congressional oversight... until he became the first President to violate the War Powers Act.

    Yeah right. Hey I'm not a friend of Obama, but I think everyone agrees that Republicans are war hawks (chicken hawks). That is, they are more accepting of going to war, funding defense contractors, and are in greater favor of using our army/bombs/might to attack people across the globe. 

    You're saying you don't like military engagements, so ... vote Republican? This makes zero sense.

    "If you don't have any fresh ideas, then you use stale tactics to scare the voters. If you don't have a record to run on, then you paint your opponent as someone people should run from. You make a big election about small things."  – Barack Obama

    Wow, talk about using the wrong context. What you quoted above was Obama describing the modus operandi of the Republicans who were criticizing him. You attempted to flip the meaning to the opposite. It's quite telling that you are so eager to disinform others.
