 Weekly Report: Back up again

The weekly reports have been dead for a while. Reason? The blog has been dead for a while.

Hardware woes

The old computer running this website had some problem all of a sudden about 3 weeks ago. These problems appeared as a complete lockdown of the system – no response to anything. So my brother – with me on the other side of a telephone, tried to reboot the box; but couldn’t get it back up online again. He was headed out to a LARP anyway within hours – and so couldn’t really do much more about it.

Right.

End result? I joined forces with a good friend of mine; we split hardware costs for a slick new box – an Asus barebone box with a 64bit processor and a gig of RAM. It received the harddrive and network interface from the old box, and was with that good to go – only .. processor architecture changed; and so for optimal performance, it’d be a nice idea to actually use a new system install that took advantage of the extra available bitwidth.

A completely failed OpenBSD installation later, we settled for Gentoo – which now is humming along nicely. It even turned out to be surprisingly easy to restore the old data on the new box.

There. I won’t blather more about my hardware woes – but instead poke about other themes for a while.

Party party party

My students here for the course rock. The REALLY rock. We had the course evaluations a couple of weeks ago – and apparently my exercise sessions has been gooooood. At least the students thought so. I average in the upper fifth of possible ratings in every single evaluation area. All of them. I kick ass, yo!

Compared – both to the faculty mean, and to the workgroup results – I outperform in all evaluated areas.

And, in addition to this cause for celebration, the end of the school term (last week) comes with all manners of parties, celebrations, meets, and activities. I think I had my first non-planned evening in about 2-3 weeks yesterday.

Summer in the city

The Jena climate, though, leaves a bit to wish for. I sincerely long to get back to Sweden during the hottest summer weeks we have up there, in order for me to cool down a bit. We have had 25°+ since beginning of June (i.e. about 2 months of active time with weekly lectures, seminars and exercise classes – in tropical bloody heat); and the last about 2 weeks or so, the temperatures have been in the upper 30°ies.

Horrible. Horrible, I tell you.

And of course, this heatwave has coincided with the World Cup, the Th

Nice to see another update. I remember the weather from southern Germany. It’s far too hot sometimes for us cool blooded Swedes. On the other hand it’s nice in the winter, even if the Germans don’t understand that 5C is “warm”.

Sounds like a nice project with your PhD. I hope to hear what you settle for even if I know I won’t be able to read most of it ;)

Haskell is a beautiful language for mathematics, but sadly I have had it demonstrated for me how exceptionally bad it is in other areas. Writing a playable game of chess (complete with graphics) in Haskell is a painful experience. Personally I consider it a curiosity at best after having had to deal with the IO functions.

Haskell IO isn’t a big deal at all. I recently tried writing some (H)OpenGL code in the IO monad in Haskell. It was no harder than writing OpenGL code in C, say. In some ways it was easier – for example it’s much easier to iterate over sets of triangles and the GLUT callbacks for window resizing, keyboard and mouse input etc. were much easier to code elegantly. You have to make use of IORefs a little bit. These are essentianlly the same as C pointers except they’re safe. And when you’re not manipulating IORefs or doing IO you can write the mathematical portion of your code using pure functional code.

On the other hand, if I felt like it I could easily present Haskell IO in a really obfuscated way that makes it much seem harder than it is.

Want your say?
