Today marks 700 years since the date traditionally regarded as the day when William Tell shot an apple off the top of his son’s head with a crossbow and kick-started a resolution against the Austrians which led to the founding of Switzerland. The legend goes that the Austrian Hermann Gessler was appointed vogt (sheriff) of … Continued
This release works around errors in capturing screen shots from certain WMV files. It also changes the default geometry from 240Ã180+0+0 to “auto” which is an automatically calculated, hopefully appropriate, geometry. Download dhyana.pl Highlighted source code
A story that seems to have had surprisingly little coverage in the British media is the fact that for almost half a year, Belgium has had no official government. Since the elections of 10 June, no government has been able to form a working majority, despite a lot of effort from the Belgian royal family … Continued
I’m told that the only thing that will bring me more traffic than pirated MP3s and hardcore porn is photos of kitties… The gorgeous models are our 15-month-old cats Chairman Meow and Mr d’Silva. Picture quality is awful as they’re from my phone. We really need to invest in a new digital camera, as the … Continued
Large PNG image Scalable SVG image I drew this map and wrote the skeleton of this article in November, but have only recently gotten around to finishing it… Empires The US is occasionally referred to as “the only remaining global superpower”. By 2050, I believe that it will still be a superpower, but that others … Continued

So, I was looking for a way to create sequential video thumbnails (like this one) from a video file on Linux. I found that my options were severely limited. On Windows there are a plethora of tools capable of this fairly simple task, including Media Player Classic, but on Linux all I could find was … Continued
Today marks the 30th anniversary of the day Elvis Presley faked his own death.
Now that fake Steve has been outed, I’m sure everyone is looking for the next fake blog. Well… Fake Bob Keefe (Who is Bob Keefe ?)
PHP lets you define your own error handler, so I decided to get a bit fancy. MegaErrorHandler (MEH) outputs its errors as specially-formatted HTML comments, with the details of the error encoded using JSON. A small client-side script, with an associated stylesheet then pulls this data out of the comments and formats it as a … Continued
I posted a couple of years ago that the command line is the interface of the future. Today I stumbled on a couple of articles that seem to agree with me: Command Line for the Common Man: Command Line Comeback The Power of Command Lines Quicksilver blows away both Apple’s Dock and Microsoft Windows’ Taskbar … Continued
The Open Mobile Alliance, who are responsible for co-ordinating the web-browsing efforts of mobile phones, seem to have misplaced xhtml-mobile12-model-1.mod. This file is a key part of the DTD for the latest version of their XHTML Mobile Profile standard, which defines how authors should construct web pages intended for the consumption of mobile phones.

Here’s an example of how to parse an HTML table into an array using the PEAR module XML_HTMLSax3. It supports the , and elements and the rowspan and colspan attributes. It’s worth noting that this code will raise a bunch of notices if you run it displaying all errors. This is pretty difficult to avoid, … Continued
On Usenet an often-asked question is how to programmatically determine the “domain” of a particular hostname. That is, excluding the components traditionally thought of as subdomains. As an example, groups.google.com and www.google.com both have a domain of google.com. Invariably, one answer comes back stating that you just need to chop off everything from the front, … Continued
Here’s a nifty bit of code I wrote a while back (utilising a function from PHP SmartyPants) that takes a bunch of HTML, searches it for some word or phrase that you specify, and turns all occurances of it into a link, unless it’s already a link!
Here's a simple program which calculates, to eight decimal places, the value of the Golden Ratio φ implemented in both PHP and Perl, to demonstrate their similarities.
