In The Method and Scope of Genetics, published in 1908, William Bateson offers this advice: If I may throw out a word of counsel to beginners, it is: Treasure your exceptions!

Motivated by a recent question from one of my department’s academic counselors, I’ve decided to start a small blog series with tips, tricks, or general advice for undergraduate students in computer science.

So you’ve written a cool thing. Maybe it’s a game that you like and want to let other people play. Maybe it’s a library that you think other people could use.

Sometimes, you want to redirect the output of your program to a file–maybe to record it for another program, or because you want to search through it with grep. If you have to do this at the C level, there are a few ways you can accomplish this.

Stop me if you’ve had this problem before. You need to ssh into a server, but it has some horribly complicated rules, so your SSH command looks something like ssh -p 9999 myuser@complicated.

I’m currently working on a project that requires the use of Molecular Dynamics simulations to generate raw data. It’s not really the focus of the project, but I do need some decently long simulations (in the neighborhood of 400ns) to get meaningful data.

Since our friends over at TACC don’t seem to like posting their SSH key fingerprints, I figured I’d go ahead and do it for them. Here are the key fingerprints as seen from the main UT campus.

Looks like I’ve finally been able to make a website! In case you’re interested in building a quick and easy personal site of your own, I highly recommend the Jekyll framework.
