In a hindsight, it appears that it could’ve been a better idea to take this photograph through the clean window rather than the one close to me. But whatever’s done — is done. Too bad it didn’t last more than couple of minutes.

No, really, have you seen it at all? I bet you didn’t because otherwise you would’ve tell the world about it — I’m using it for quite a while now, and I can firmly say: this is a program which just works, and makes my life substantially easier.
What is it anyway? Here you go: [...]

So very true, really! Too good my manager feels quite comfortable with me using JSON, Python and Hadoop =)
Shortly — it works. Took me almost an hour to get through 12 km — mainly because many times I slowed down to actually understand, where should I turn, as GPS (being guided by pre-defined route) provided me very little help should something go wrong. But I did it anyway — and CycleStreets did show [...]
Pretty good looking, can moderate/answer comments and upload pictures – sounds good, as far as I’m concerned.
Perhaps, I’m not an only one who uses WordPress as a blogging platform of my choice — surely it’s my domain and my hosting, but still. Recently I’ve discovered very neat and nice way of backing up your entire blog, which can be described in a few simple steps:
