  • Physics System ignores collision in some rare cases

    - by Gajoo
    I've been developing a simple physics engine for my game. since the game physics is very simple I've decided to increase accuracy a little bit. Instead of formal integration methods like fourier or RK4, I'm directly computing the results after delta time "dt". based on the very first laws of physics : dx = 0.5 * a * dt^2 + v0 * dt dv = a * dt

  • 5 Android Keyboard Replacements to Help You Type Faster

    - by Chris Hoffman
    Android allows developers to replace its keyboard with their own keyboard apps. This has led to experimentation and great new features, like the gesture-typing feature that’s made its way into Android’s official keyboard after proving itself in third-party keyboards. This sort of customization isn’t possible on Apple’s iOS or even Microsoft’s

  • Nodemanager Init.d Script

    - by john.graves(at)oracle.com
    I’ve seen many of these floating around.  This is my favourite on an Ubuntu based machine. Just throw it into the /etc/init.d directory and update the following lines: export MW_HOME=/opt/app/wls10.3.4 user='weblogic' Then run: update-rc.d nodemanager default Everything else should be ok for 10.3.4. #!/bin/sh # ### BEGIN INIT

  • ADF version of "Modern" dialog windows

    - by Martin Deh
    It is no surprise with the popularity of the i-devices (iphone, ipad), that many of the iOS UI based LnF (look and feel) would start to inspire web designers to incorporate the same LnF into their web sites.  Take for example, a normal dialog popup.  In the iOS world, the LnF becomes a bit more elegant by add just a simple

  • Runge-Kutta (RK4) integration for game physics

    - by Kai
    Gaffer on Games has a great article about using RK4 integration for better game physics. The implementation is straightforward but the math behind it confuses me. I understand derivatives and integrals on a conceptual level but I haven't manipulated equations in a long time. Here's the brunt of Gaffer's implementation: void

  • OCR an RSA key fob (security token)

    - by user130582
    I put together a quick WinForm/embedded IE browser control which logs into our company's bank website each morning and scrapes/exports the desired deposit information (the bank is a smallish regional bank). Since we have a few dozen "pseudoaccounts" that draw from the same master account, this actually takes 10-15

  • Java language features which have no equivalent in C#

    - by jthg
    Having mostly worked with C#, I tend to think in terms of C# features which aren't available in Java. After working extensively with Java over the last year, I've started to discover Java features that I wish were in C#. Below is a list of the ones that I'm aware of. Can anyone think of other Java language

  • CSS sliding doors technique for buttons, IE8 problem

    - by Kelvin
    Hello All! I used sliding doors technique, explained here: http://www.oscaralexander.com/tutorials/how-to-make-sexy-buttons-with-css.html With only one exception, that I decided to add one more image for "hover" effect. My code works well for all browsers, except IE8 (and maybe earlier versions).

  • Modeling distribution of performance measurements

    - by peterchen
    How would you mathematically model the distribution of repeated real life performance measurements - "Real life" meaning you are not just looping over the code in question, but it is just a short snippet within a large application running in a typical user scenario? My experience shows that you usually

  • Code Golf: Evaluating Mathematical Expressions

    - by Noldorin
    Challenge Here is the challenge (of my own invention, though I wouldn't be surprised if it has previously appeared elsewhere on the web). Write a function that takes a single argument that is a string representation of a simple mathematical expression and evaluates it as a floating point

  • stdio's remove() not always deleting on time.

    - by Kyte
    For a particular piece of homework, I'm implementing a basic data storage system using sequential files under standard C, which cannot load more than 1 record at a time. So, the basic part is creating a new file where the results of whatever we do with the original records are stored. The previous

  • Reading Source Code Aloud

    - by Jon Purdy
    After seeing this question, I got to thinking about the various challenges that blind programmers face, and how some of them are applicable even to sighted programmers. Particularly, the problem of reading source code aloud gives me pause. I have been programming for most of my life, and I
