Should PC’s be easy to use for everyone, or should you actually need some kind of understanding of how they work?
I recently saw an article about a new computer aimed at “computer illiterate” users, the Alex PC. Elsewhere on the ‘net, people were arguing about whether or not trying to make it easy for “non-geeks” to use computers and internet was a good idea or not, which provoked some thoughts which I thought I’d share.
Here’s a question I was pondering a couple of days ago: Can you make JavaScript’s String object mutable, as in modifiable without having to re-assign the string.
Why would this be useful? Sometimes you might share a string between objects, and you’d want changing it in one place get reflected in elsewhere. If you had a single string object, which was referenced from multiple places, this would be simple.
But it turns out, it isn’t…
During my adventures in programming, I’ve been involved in many projects. Luckily, despite having made some mistakes, they’ve gone quite well. Here are a few of them, with tips on how to avoid making them yourself.
Time for some consumer advice today.
I’m sure many of us have often thought about getting headphones – and I’m sure many of us already have a pair – but how much is a reasonable amount to spend? And what will a higher-grade (read: more expensive) pair do that’s worth the money?
I recently decided to invest on some new headphones. The AKG K 701’s to be precise. They aren’t exactly very cheap and you’d probably want a headphone amplifier to go with them, one which I incidentally also bought. I’ve also had some more reasonably priced headphones in the past: Sennheiser HD-555’s and going down in the price range, some Koss and Philips ones.
My opinion is that great headphones can make listening to music much more enjoyable. However, should you go all out and buy expensive ones like the AKG, or is it smarter to purchase something else?
As I’ve been rewriting TankWar, I’ve been thinking of various approaches to displaying the game’s graphics. At the moment, I can count three feasible approaches for rendering game graphics:
I’ve considered each of these, and they all have some pros and cons which we’ll look at next.
In the tradition of end of the year posts, here’s some “best of” statistics from this blog for the year 2009.
Next week we will return to our regular programming.
Here’s a quick tip for Opera and Vim users: How to add a menu item which allows you to quickly open highlighted text on a web page in Vim.
This trick can be applied with any other application too, like <insert your favorite editor>
I have decided to rewrite TankWar, and I’ll be writing a bunch of blog posts about the process. If you ever wanted to know how to write a scorched earth/worms-like game using just JavaScript, now is your chance to learn ;)
This is the first one: Assessing the damage. In other words, take a look at the old code and see what can be salvaged. I’ll also list some issues with the current implementation, and how I plan on solving them in the new version.
Interactive rebase is one of my most used Git commands. It’ll let me slice and dice commits in various useful ways. Here’s a few tips for you to unleash the true potential of rebase :)
You may recall an earlier post about TankWar, my 100% JavaScript cannons-game. Back when I wrote it, I included online play, but the server went down with a hard disk failure.
Now, I have rewritten the online mode – this time that part is also all JavaScript – continue reading to find out what makes it tick.
