  C/C++ Pointer Declaration Syntax – It makes sense!

I never really liked the way pointers are declared in C/C++: int *a, *b, *c; // a, b and c are pointers to int The reason is that I am used to reading variable declarations as MyType myVar1, myVar2, myVar3; and I always read “int*” as the type “integer pointer”. I therefore wanted the following int* a, b, c; // a is a pointer to int, b and c are ints to mean that a, b and c all were of type int*, i.e. pointers to int. and I therefore found it slightly a...

  How To Write A Good Programming Test

I’ve taken and marked a lot of programming tests in the past. I love doing them as it’s always good to see what challenges different programmers have come up with when designing them. Unfortunately, however, most of them aren’t very good. Below is a list of general ideas to help increase the quality of programmer tests. 1. Keep it relevant Too many of the tests have questions on content that simply isn’t relevant to the job. The whole idea behind a programming test i...

  Programming: the benefits of taking a break

This post lists several benefits of taking a break during programming.You work smarter, not harder. Once, I worked really hard on a feature. For two weeks, 12 hours a day, I put in a lot of effort. After those two weeks, I took a break and came up with several ideas that made much of the work unnecessary.You think more clearly. Being tired has a similar effect as being drunk. At the end of a day, I often kid myself that I’ll just get this one thing finished quickly to have a fre...

  Tips for a better first-time hackathon experience

Here are a few things you can consider. These are by no means the only way to go about hackathons, just what's worked for me.ProjectI strongly strongly recommend doing something you haven't done before. Even if you're going into a hackathon with the intention of winning, trying something new is always fun and will keep you engaged throughout the event. Jump into mobile development, try hardware hacking, write a compiler, whatever; it's always fun to try out new things.Sticking to things you're c...

  Paint messages will come in as fast as you let them

There is a class of messages which are generated on demand rather than explicitly posted into a message queue. If you call Get­Message or Peek­Message and the queue is empty, then the window manager will look to see if one of these generated-on-demand messages is due, messages like WM_TIMER, WM_MOUSE­MOVE, and WM_PAINT. Neil wonders, "In that program that called Invalidate­Rect 100,000 times, how many paint messages were generated?" The Zen answer to this question is "Yes." A ...

  A Javascript When Function

function when(conditionFunc, execFunc, interval){ if (conditionFunc()){ execFunc(); }else{ setTimeout(function(){ when(conditionFunc, execFunc, interval);}, interval); } } You have some code which should only execute when a condition is true. E.g. You have code which relies on a javascript library but can't be sure the library has loaded yet and don't want the code to execute until it has.
