Class is now done. My last final exam was yesterday. More than any previous semester, I used a wide variety of computing tools to finish my work in class. Here are a few of the ones I put to use:
1.
Weka, an open source machine-learning workbench (I used it in bioinformatics but it is a general-purpose tool that could be applied to any field).
5.
OpenGL for writing a 3D game for graphics class.
6.
Wings3D for creating 3D meshes for my game.
7. The open-source
R Project for statistical analysis of data. I also used it for my Stats 221 class.
Posted for future reference

I really don’t like blogging about this kind of thing, but the battle between my stomach and my conscience often leads to a win for the conscience. The United States should be a world leader in moral capacity and ethical treatment of even the vilest of characters. Somehow, we failed at that role between 2002 and 2007. FireDogLake reports:
According to the May 30, 2005 Bradbury memo, Khalid Sheikh Mohammed was waterboarded 183 times in March 2003 and Abu Zubaydah was waterboarded 83 times in August 2002.
The author concludes:
The CIA wants you to believe waterboarding is effective. Yet somehow, it took them 183 applications of the waterboard in a one month period to get what they claimed was cooperation out of KSM.
That doesn’t sound very effective to me.

I liked this article by John Sviokla about why people are willing to work for nothing: it’s a different economy altogether. Once a person has left the ground-level of income-for-survival and is flying in the upper stratosphere of meaning, purpose and contribution it makes little sense to desecrate that higher ideal with a token payment in dollars.
I think most people, like me, straddle both economies: we do some things out of a pure intent to help, and other things to pay the bills. The in-between is somewhat murky and can either feel like we have to compromise our ideals due to the reality of life, or else change our ideals.
There’s more to think about here, but I have finals this week so I have to go. Perhaps I’ll write again on the subject soon.

Wow. Just in case Github wasn’t already the coolest social site for coders, it now has “issues”—a bug tracking area for each software project. And it gives everyone the ability to vote for the issues they most want fixed!
This is really awesome. Git and Github have already revolutionized how software can be created by distributed teams—and now I think we’ll see a further democratization of software development with this feature. Way to go
mojombo and team! :)

This New York Times article talks about the malleability of intelligence and the recent evidence that shows IQ is not quite as genetic as was once thought. Anyway, this little snippet kind of blew me away:
Another indication of malleability is that I.Q. has risen sharply over time. Indeed, the average I.Q. of a person in 1917 would amount to only 73 on today’s I.Q. test. Half the population of 1917 would be considered mentally retarded by today’s measurements, Professor Nisbett says.
I’ve always suspected that there is a gentle progression toward a more educated, intelligent society. But I thought it was only visible on the order of thousands of years. If true, this claim by Prof. Nisbett will require me to update my views. I suppose if you consider education as the factor that has improved our IQs on average (rather than genetics), that claim makes sense. We are better organized today, in spite of the disaster that is No Child Left Behind. In any case, I hope we can continue this upward trend in education so that children 100 years from now can look back on my youth and remark that I must have been mentally retarded

This adventure took longer than I expected, so I am posting what I’ve found here for others. The goal is to create a CD with a custom icon for Mac OS X, with one caveat—it needs to be created on a Linux system. The software to use on Linux is called “cdrtools” and includes a command-line tool, “mkisofs”. You can also install cdrtools on the Mac (using the MacPorts system) for testing purposes with “sudo port install cdrtools”. Here’s the recipe:
1. Find or create a “.icns” file that includes the icon you would like the CD to have when you pop it in the drive. I found a
hint here that helps you to convert a regular Mac OS X icon to a .icns file. [Note: this step was done on a Mac]
2. Copy or move the file to a directory with the contents of the CD. Rename it as “.VolumeIcon.icns”. The preceding dot is important, and the name must be exact. I used the shell / Terminal to do this since the Finder isn’t always friendly to seeing and creating hidden files.
3. Create an empty “Icon\r” file in the directory. In the terminal, I can do this with “touch Icon^V^M” where “^V” means “control V” and “^M” means “control M”. Just the existence of the file is enough–it tips the operating system off to know that it should use the .VolumeIcon.icns file. [Note: it appears to be possible to also use the "SetFile -a C mycd/" command when on a Mac to change a bit on the directory itself. This bit also notifies the operating system that it should use the .VolumeIcon.icns file---however, SetFile is not available on Linux.]
4. Use mkisofs to generate the iso file:
mkisofs -hfs -r -V ‘My CD’ -o mycd.iso mycd/
This assumes the contents of the CD (as well as our two files above) are in the mycd/ directory. Once the mycd.iso file has been generated, it can be burned directly to a CD.

When I first heard about the attempted spying on our US infrastructure and subsequent early discovery of the infiltration, I thought “Oh, whew, good thing we caught them.” But on second thought, Robert Graham has a good point: is this another one of those Bush-era “few facts and government officials said” stories? Could it be part of a PR campaign to convince us that we need to give the president power to “switch off the internet” so to speak?

Here is an update from Ron Paul on the “Audit the Fed” bill I mentioned a few weeks ago. We have about 39 cosponsors to the bill now which is very encouraging. I hope that if you also want to see increased transparency in government you’ll take a moment to encourage your congressperson or senator by writing to them.
