  Guest Post from a CodeBoy: The Five Stages of Debugging

Being confronted with a serious and difficult-to-diagnose bug can be one of the most traumatic and stressful experiences of a professional programmer's career. Those who have been through such an ordeal rate the stress as on a par with that accompanying serious injury, divorce, or the death of a family member. Researchers who have studied the psychology of computer programming have lately constructed a framework to understand the stages through which the programmer's mind progresses as she...

  Windows 8 Possible Features: Ribbon, Metro, Apps, Cloud Integration

Microsoft may still be plugging away at selling Windows 7 to consumers and the enterprise, but rumors have already started about the next version of the popular operating system—dubbed "Windows 8" by many in the media. Rafael Rivera and Paul Thurrott, two bloggers with a track record of delving into Microsoft's proprietary code base, recently sparked a fresh round of chatter with a dissection of a supposed Windows 8 early build, adding their voices to a discussion that extends back to 201...

  Difference Engine: Luddite legacy

AN APOCRYPHAL tale is told about Henry Ford II showing Walter Reuther, the veteran leader of the United Automobile Workers, around a newly automated car plant. “Walter, how are you going to get those robots to pay your union dues,” gibed the boss of Ford Motor Company. Without skipping a beat, Reuther replied, “Henry, how are you going to get them to buy your cars?”Whether the exchange was true or not is irrelevant. The point was that any increase in productivity required...

  Developing Game Audio with the Web Audio API

Caution: This article discusses APIs that are not yet fully standardized and still in flux. Be cautious when using experimental APIs in your own projects. Introduction Audio is a huge part of what makes multimedia experiences so compelling. If you've ever tried watching a movie with the sound off, you've probably noticed this. Games are no exception! My fondest video game memories are of the music and sound effects. Now, in many cases nearly two decades after playing my favorites, I still c...

  Battlelog: Modern Web Applications are Here

It's the shooter season of the year and this fall was all about Modern Warfare 3 versus Battlefield 3. And being the kind of game they are they also try to keep their audience playing by introducing some additional level of engagement. Both Call of Duty and Battlefield introduced their own online community websites and statistic platforms. Call of Duty has Elite, Battlefield has Battelog.But just because these services are sitting in the same spot it does not mean they are in any way similar. An...

  That “JavaScript not available” case

During some interesting discussions on Twitter yesterday I found that there is now more than ever a confusion about JavaScript dependence in web applications and web sites. This is a never ending story but it seems to me to flare up ever time our browsing technology leaps forward. I encountered this for the first time back in the days of DHTML. We pushed browsers to their limits with our lovely animated menus and 3D logos (something we of course learned not to do again, right?) and we were ...

  A Programmer’s Greatest Enemy

A programmer’s greatest enemy is getting stuck. A crucial skill in programming—and one that many of my beginning game programming students lack—is the ability to recognize when they’re stuck, to get out of being stuck, and to avoid getting stuck in the first place.Indeed, it’s a skill I’m still learning myself, although the contexts in which I still get stuck are shrinking with time, study, and experience.This morning, as I downloaded crash reports ...

  How Integers Should Work (In Systems Programming Languages)

My last post outlined some of the possibilities for integer semantics in programming languages, and asked which option was correct. This post contains my answers. Just to be clear: I want practical solutions, but I’m not very interested by historical issues or backwards compatibility with any existing language, and particularly not with C and C++. We’ll start with: Premise 1: Operations on default integer types return the mathematically correct result or else trap. This is th...
