For the minimalist programmer, there's vim. For everybody else, there's SlickEdit.

For those of you playing along at home, you'll recall that our intrepid hero is working on a shell script that can tell you the most recent year that a specific date occurred on a specified day of the week—for example, the most recent year when Christmas occurred on a Thursday.

Rubies, Pythons and Perls! It may sound like a new Indiana Jones movie or possibly a cheesy platform-style video game from the 1990s, but the title of this column actually refers to our focus this month—programming! Not that there's anything wrong with daring adventures in remote locations, it's just that all the red tape can be overwhelming.

A short while ago, an article appeared in Linux Journal implying Git was the be-all and end-all of source code revision control systems ("Git—Revision Control Perfected" by Henry Van Styn, August 2011).

In previous articles, I've looked at a number of uses for JavaScript, on both the server and the client. I hope to continue my exploration of such systems, particularly on the client side, in the coming months.

Perl has been around for more than 20 years. During that time, it has received its share of both praise and criticism, and lots of misconceptions surround it. Much of this stems from long-outdated notions of what Perl used to be, but have nothing to do with what Perl actually is today.

jEdit is a cross-platform text editor written in Java.

A few months ago, I wrote a piece about how you can use MPI to run a parallel program over a number of machines that are networked together. But more and more often, your plain-old desktop has more than one CPU. How best can you take advantage of the amount of power at your fingertips?

I've been covering various scientific programs the past few months, but sometimes it's hard to find a package that does what you need. In those cases, you need to go ahead and write your own code. When you are involved with heavy-duty scientific computing, you usually need to go to parallel computing in order to get the runtimes down to something reasonable.

In 2005, after just two weeks, Linus Torvalds completed the first version of Git, an open-source version control system. Unlike typical centralized systems, Git is based on a distributed model. It is extremely flexible and guarantees data integrity while being powerful, fast and efficient.

Some interesting items showed up under Dave's Christmas tree, including a new book by some old friends, a laptop keyboard (music, not QWERTY), and an excellent Linux audio plugin for high-quality reverb. Dave must have been a very good boy last year.
