Colorbar: belgian spam

Colorbar: belgian spamIn the last three days I have received 3 mails from Colorbar, a “lively private club for colorful people”. The first one didn’t trigger my suspicion, since I am subscribed to some music-related mailing lists. The two next mails came for 2 aliases of which I am certain they never subscribed to any list. So I took a closer look at the email. No contact details are given, no indication of where the email addresses came from, no possibility to unsubscribe, i.e. it’s a spam mail. To be even more specific: a belgian spam message.

Tangotation: writing tango steps

I have been looking for a way to write down tango steps since I began dancing. I experimented with drawing arrows, writing full text, abbreviations, inventing signs, … I’m not alone in this quest:

Brussels Tango on Google Calendar

I’ve started a public Google calendar for tango events (milonga’s, salons) in and around Brussels. My preferred site, has gone down, the agenda at is quite ugly (it uses frames *shiver* ), and Marisa & Oliver’s agenda cannot be exported. So I made my own:

Rule of thirds for Powerpoint

Just a thought I had:
if the “rule of thirds” is so effective for photo composition, could it also be used to create more pleasing Powerpoint presentation designs?
An example of the layout dimensions could be like this (don’t focus on the boring picture/font, just the relative placement):

iPod in 2009: more storage or bandwidth?

I had an interesting discussion some days ago: will the iPods move to more storage (e.g. the Terabyte iPod) or more bandwidth (Bluetooth, EDGE, Wifi). Let me sketch what those two scenarios for the future iPod look like:

A Sudoku challenge generator

When on holiday, one can kill time solving Sudoku puzzles. When one has done a dozen of those puzzles and one happens to have a wandering mind like mine, one starts wondering how those Sudoku challenges are created, and if it would be possible to describe an algorithm that can make such a scarcely filled-in 9-by-9 grid. Some sunny hours later one has a system that might work (I haven’t implemented it fully yet). For my future reference: here’s how I would do it.
REMARK: this algorithm is quite logical and as such, I seriously doubt I would be the first one to think of it. I can imagine that Sudoku puzzles are already made by the hundreds with a program that uses this or a quite similar system. I’m not claiming it’s an original ‘invention’, just a fun problem to tackle.
