Google’s closure compiler is an impressive tool that parses JavaScript code and make various optimizations on it, including minimizing its size. This post will provide what is needed to effectively utilize it in minimum time. Step 1 – verify consistant property access methods in your code ∞ The first thing you should do is make …

I’m excited at the speed of the computer’s moves. Almost all moves take less than a second on my MacBook Air (1.86 GHz Intel Core 2 Duo) – the times when a move requires about 3 seconds is when the computer analyses how to play a joker. Did I already mention this is pure JavaScript …
After making a small change, I’ve managed to improve the algorithm so that the computer will make a move in under a second every turn. Considering this is all written in pure JavaScript and runs on the browser, I’m starting to wonder whether the algorithm I wrote is the fastest existing scrabble algorithm out there…
The nice thing about having a blog site that no one knows about is that if you’re creating a project and you don’t want potential competitors to know what you are up to, you can freely shout all your new ideas and features to the void… 🙂 The English JavaScript is working nicely so I’ve …
Making progress with the Scrabble clone. Also made changes so it will even work on IE6. There is still the 10% of polishing work that takes 90% of the time, but its fun so I’m not complaining. Its great to see that the number of words in the dictionary have no noticeable effect on the …
It took me almost two weeks but I’m nearing completion of an implementation of a fast Scrabble game against the computer written in pure JavaScript. It is both fast (less than 3 seconds per move) and unbeatable. Here you can see the browser (playing in Red) giving me a humility lesson (playing in Green)… First …
I’m in the process of developing a CPU intensive Javascript game. I found the profilers of the different browsers lacking and needed some higher resolution probing of CPU hogger sections in the code. To this effect I created the timers manager below. Basically at any point in the code where you want to start measuring …
I’ve been looking at some JavaScript libraries to be used for data visualization – there are quite a few, from impressive heavy duty data visualization frameworks like D3 (which requires modern browsers that support SVG) through powerful vector rendering libraries like Raphaël that work across almost all browsers and versions using SVG or VML for …
While comparing the efficiency of my iterative method for generating combinations vs. the recursive method shown at the Rosetta Code site I picked up on a pattern that at first glance is not obvious so I’m still looking into it. It seems that the ratio of the efficiency between the algorithms seems to approach the …

For some experiment I’m conducting, I needed to generate all permutations given a number of slots and a number of symbols. I also didn’t want to use built-in libraries like Python or other languages have to generate them, so I picked Lua to avoid being tempted to do so (and because its a cool language). …
