GPSDrive on OS X

After getting GPSd to compile on OS X, I set my sights on GPSDrive, an open source navigation and map viewing program. When I posted about GPS a couple years ago, I installed GPSDrive, using the version from Fink. However, the latest version of GPSDrive on Fink nowadays is 2.08pre12, while the latest stable release […]

Neal Stephenson’s novel CryptonomiconĀ is a fascinating book; I’m re-reading it for the umpteenth time and loving it every bit as much as when I first read it in 7th grade. One thing that caught my attention on this reading (especially in light of my recent GPS post) is the way that one of the main […]

GPSd under OS X (revisited)

It’s been almost 2 and half years since I originally posted about GPSd and OS X. That post got quite a bit of traffic for a while, but a whole lot has changed since then. If you’re interested in some in-depth background information, you should check out the old post; this post is mostly about […]

M-Set update

So, I know that I’ve been harping on this a bit, but I’ve re-written my M-Set renderer in C, so it’s faster, and I’ve added a few more command line flags to make it easier to use. Get the code here.

More Mandelbrot

I just recently revisited the M-Set code from my Perl Snippets post. The code I had was pretty ugly, so I decided to rewrite it in Python. The result is not only a lot cleaner and easier to understand, but it’s also a lot faster: $ time python mandel.py > \dev\null real 0m0.051s user 0m0.036s […]

However, I have a couple short scripts that I’m just dying to share. Just Another Perl Hacker I figured that it was about […]

GPSd under OS X

Update 7-13-11: I’ve posted an updated set of instructions on getting GPSd to compile on OS X here; this post will remain for archival purposes. For information on installing GPSDrive, see this post. So I recently picked up a cheap GPS module on Amazon. It was about $30 with shipping, and I got a neat […]

Fast and Simple Stock Quotes Using Perl

One of the things that makes perl so powerful and fascinating is the huge number of modules that are available online, especially through the CPAN repository. Today I stumbled upon one called Finance::Quote, which does one thing, very simply: it retrieves stock (or mutual fund) quotes. You feed it a ticker symbol and it gives […]
