Load balancing on the cheap is easy, especially if you don't require state. Stick two servers in different places, and create a DNS entry with both IP addresses in it. Your DNS server will then give out first one address, and then the other, balancing...

Everyone knows carrots help you see in the dark. Except they don't. In World War 2, the Brits invented radar, and used it to their advantage during night flights. The Germans were wondering how the Brits could "see" so well in the dark, so to prot...

I saw some graffiti in Bristol (here), and it made me think. The best things in life are not things. Although some things are very cool. :)

Well, I've eaten at quite a few curry houses in my time. And there are a couple that are worthy of mention. The latest one I'm liking is 4500 from Delhi. The chicken Chettinad is my favourite right now. And they have an amazing lunch buffet. The B...

So, I've just got back from a month in Argentina, and I've loved it. We rented a flat in Buenos Aires, did sight-seeing, got drunk in La Boca, caught a ferry to Uruguay and ate chivito, stayed at a country house in Entre Rios, rode horses, ate loads ...

I wanted to write websites, so I learnt PHP. Nice and easy. Lots of example code. I then wanted to write stuff that ran on my Nokia N95 phone, so I learnt J[2]ME. Trickier. Debugging random network glitches/dropouts was a pain. I then went further down ...
