What an imaginative title!

Today (actually yesterday, but I’m acting as if I wrote this up yesterday, when yesterday was still today, okay?) I had the typical IEEE Vis problem of Too Many Very Cool Things All at the Same Time(TM). I chose to start with the Illustrative Visualization tutorial. One of the highlights of this was Stefan Bruckner’s presentation of his Style Transfer Functions. Stefan is a brilliant presenter, and this deceptively simple idea makes it possible to render, in real-time, illustrative volume renderings with all kinds of cool lighting possibilities. See the figure below:

Hi there gang!

I’m spending the week in the Hyatt Regency Sacramento (that’s in California, US and A!) at the IEEE Visualization 2007 conference. I’ll try and write more posts if anything with significant bloggability comes up. Until Monday, there are mostly tutorials and the InfoVis conference and on Tuesday Vis itself starts. The difference between InfoVis and (Sci)Vis is a hotly contested topic about which I’m not even going to try to comment here. However, this is a brilliant topic to discuss in bars with visualisation people, as is the difference between visualisation and visualization.

I’m peppering this with enough keywords so that other idiots will be able to find this easily. MXit is a mobile-phone based chat system that’s very popular in South Africa (Rugby World Cup champions 2007, thank you very much; want to wine about Cueto’s “try”, then first click here). It is possible to run the MXit Java midlet on a J2ME emulator (am I saying this right?) such as mpowerplayer or microemulator. Of course this works on Windows, even the average 12 year-old MXit user can successfully follow the many guides available online and then brag about his technical prowess online to his “friends”.

Somehow I missed this when searching for something like it the previous time, but Parallel Python (now found via Bruce Eckel’s blog) is exactly what I’ve been looking for.  A simple process pool that can run on multiple cores or on a cluster of machines!

DeVIDE has recently acquired the ability to run in black-box (gui-less) mode, so that networks can also be executed via some other coordination framework, such as Nimrod (see our paper on this, mail me if you want the fulltext).  However, seeing that I’ve neatly abstracted out the interface part of DeVIDE (you can choose between wxPython, simple xml-rpc, command-line with Python driver script, even PyRo), integrating ParallelPython would be a cinch.

This official GMail blog post announces that the GMail storage counter will be increased even faster… let’s have a look at my gmail.com account:

You are currently using 1541 MB (52%) of your 2911 MB.

What I find even more exciting, is that Google is going to give the free GMail for Domains accounts, which until now were limited to 2GB, the same space counter as normal gmail.com accounts.  As some of you might know, I’ve been rerouting all my work mail (mostly tudelft.nl) to my medvis.org GMail for Domains account.  I have yet to come across a MUA that suits me better than GMail.  Let’s have a look:

HI THERE GANG! If you don’t like long-winded introductions, skip to the bit starting with “THE NITTY GRITTY”.

Getting Things Done (GTD, see here for the book, here and here for introductory information, and here for a cool workflow diagram) by David Allen is a master-piece. Having read it, most of it kind of fits. It’s almost as if, if one had had the time to sit down and think for long enough, one would have come up with the same brilliant tips. But one hadn’t, so one didn’t. The Delete-Do-Delegate-Defer monster, contextual todo-lists (Work-Computer, Home, Calls, Errands, etc.), the Weekly Review(tm) and actionable next actions are some of the most valuable things I picked up when I read this book about a year and a half ago.

This is really one of those notes to self one leaves all around the show and is later so surprised about when Google finds it in a few years time, thus saving one’s hide. Again. It’s like Back to the Future, only different.

So today I was plagued by BAD_POOL_CALLER BSODs at every single restart on my XP SP2 HP NC8430 laptop (acronyms rule o.k.). I fired up my windbg, pointed its symbol file path at “SRV* c:\dbgsymbols* http://msdl.microsoft.com/download/symbols” (you should probably remove the spaces after the *s) and loaded the latest memory minidump from windows\minidump (XP makes these by default). The backtrace pointed out the culprit: It was ati2evxx.exe, the infamous i’m-not-sure-what-exactly-i’m-doing-on-your-system ATI hotkey poller. First I nuked it with the brilliant sysinternals procexp, and then permanently nuked it with the equally brilliant sysinternals autoruns. My problems are over. I also feel better after nuking ati2evxx. TAKE THAT, YOU SOULLESS STEAMING P.O.S. SOFTWARE!

With this I’m doing my bit to spread this news in my part of the blogosphere (*cough* I’m not supposed to use that word, EVAR).

It turns out that Bush knew all along that Saddam had absolutely no WMDs, but that the decision had already been made to invade Iraq, and that the intelligence was simply twisted to fit this policy. Read all the nasty details in this Salon article. Here’s a choice excerpt:

(For The Impatient and Those With Important Things to Do: this is a long story about Ubuntu Gutsy Gibbon and how Linux Powertop can help you to make you laptop battery last longer. It has pictures. At the end.)

One of the main problems I had with Ubuntu 7.04 (Feisty Fawn) as you will recall, was the extremely poor power management. You don’t spend thousands of euros on a laptop to install an operating system on that drains its batteries in half the time it takes Windows to do the same.
