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 attempting to scan a document with my newly purchased HP Deskjet 3070 All-in-One Printer B611b from my Ubuntu 12.04 desktop I learned three things: There’s an excellent scanning software for Linux called XSane Ubuntu 12.04 comes with the drivers for most HP printers already built in, so there was nothing else needed other then …
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). …
It took me a while to converge to a decision regarding what cross platform mobile development platform I should commit myself to (at least in the foreseeable future). After considering the various frameworks, I came to the understanding that MoSync is the winner for me. The reasons are that MoSync best matches my view on …
Endless volumes have been written about the problems associated with the growing complexity of software. It is interesting how the ancient story about the tower of Babel seems to be materializing in the form of broken communications between software applications located on different hardware products and vendors. I don’t claim there is a silver bullet …
Took a couple of hours to create an old game I played about 30 years ago on a friend’s digital watch… I don’t remember the model of the watch, the name of the game or even the friend’s name, but I do remember everyone took turns trying to play and beat the high score. The …
For some reason there’s an old song I learned at school more than 35 years ago, whose tune and lyrics I can still remember. It goes like this: I hear echoes that are dear to me that whisper oh so sweetly to my heart You must come, come to those you love across the sea …
I’ve added a new JavaScript 4K page will host JavaScript games that are contained in one html file which is no larger than 4K. This is an even more difficult constraint than the Java 4K challenge since the Java files are in compiled bytecode whereas Javascript is at most minified source code. The gallery currently …
The ITU did not create the Internet. There was no way it could. The Internet could only be created by engineers who celebrate freedom, openness, sharing, curiosity, innovation and even humor – values that have made the Internet what it is, and which the ITU lacks. As an engineer, this comes across in a striking …
