Automate Everything
Performing manual, repetitive tasks enrages me. I used to think this was a corollary of being a programmer, but I’ve come to suspect (or hope) that this behaviour is inherent in being human. But being able to hack together scripts simply makes it much easier to go from a state of rage to a basic solution in a very small amount of time. As a side point, this is one of the reasons that teaching the basics of programming in schools is so important. It’s hard to think of any j...
A Brief Guide to Voice Navigation and the Future of UX Design
Voice devices are now everywhere, whether you like them or not. Amazon's Alexa, Google's Assistant, and Apple's Siri have proved that voice interactions are not from science fiction films but part of our new reality. Just as touch screens, voice interaction with devices will completely revolutionize how we interact with our computers, smartphones, and watches (and even cars and houses) in the coming years. But you might ask yourself, why is it evolving at such a fast speed? Well, there are many ...

The Death Of The Spec
Earlier today, my colleague Matt Burns wrote a post noting that most tablet makers may be largely failing because they’ve sold their soul to Android and are now just in the middle of a spec war, which no one can win. I’m gonna go one step further in that line of thinking: the spec is dead.There have been a few key stories from the past couple of weeks that highlight this new reality. Barnes & Noble unveiled the new Nook Tablet. Consumer Reports looked at the...

Why I switched from Ruby back to C++
After two months of Sol Trader development in Ruby, I took a difficult decision last Wednesday morning: I’ve decided to rewrite the game code from scratch in C++. Let me explain my reasons. If you'd like to receive announcements about Sol Trader or be part of the beta program, sign up at soltrader.net. Why I did it Slow frames: When working with Ruby, I use the excellent Gosu library to do all my game specific coding. This initially worked great, but occasionally I’d just...
Method chaining and lazy evaluation in Ruby
Method chaining has been all the rage lately and every database wrapper or aything else that’s uses queries seems to be doing it. But, how does it work? To figure that out, we’ll write a library that can chain method calls to build up a MongoDB query in this article. Let’s get started! Oh, and don’t worry if you haven’t used MongoDB before, I’m just using it as an example to query on. If you’re using this guide to build a querying library...

Coder or Clown?
That’s the challenge. Sit down with someone you’ve never met and try to work out if they are a coder or a clown. I don’t mean to insult anyone, of course, and I’m the first to acknowledge the years of training and effort that goes into being a professional clown. But some coders, oh boy. Like the time I interviewed a recent graduate. I’ll call her Ada. Full of sympathy for the novice programmer I started with a gentle warm-up, a soft-ball question to break the ...
How NOT to teach a computer language
For the past year or so my wife has been taking online classes to get a computer science degree. For most of her classes she’s done great, she’s been flying through HTML and SQL, even up to the point where she can handle multilevel joins and optimizing through indexes. That was until she hit her vb.net class. I had no idea why she was having problems with a language has easy as vb.net so I started helping her out and find out why she was having so many problems. I’ve also ad...

A Better Way to Learn How to Program
Learning how to program can be a nightmare. An aspiring coder has to jump through many unpleasant hoops and mysterious error messages just to get "Hello, World!" printed on the screen. Then, she's left wondering, "OK, now what? How do I actually build something?"As game developers seeing someone struggle through this, we should be screaming, “NOOOOO!†The whole thing reeks of bad game design: a lot of work with no reward, unclear failure cases, advanced features pushed on new players...

Live in Beijing and Thinking about Starting a Tech Company? Read. This. Post. Now.
The Disrupt Beijing Hackathon starts in a little more than 24 hours, and we’ve been working hard over the last few days to make it even more of a no-brainer for local Beijing developers to attend.In addition to the chance to be the next GroupMeor win valuable prizes, we have decided to give all Hackathon attendees who complete a hack and present in the 24-hour period free tickets to the Disrupt conference Monday and Tuesday. That’s a $1,000-plus value for s...

Building a Modern Web Stack for the Real-time Web
The web is evolving. After a few years of iteration the WebSockets spec is finally here (RFC 6455), and as of late 2011 both Chrome and Firefox are SPDY capable. These additions are much more than just "enhancing AJAX", as we now have true real-time communication in the browser: stream multiplexing, flow control, framing, and significant latency and performance improvements. Now, we just need to drag our "back office" - our web frontends, app servers, and everything in between into this cen...
