How to disable Tiger’s Dashboard

Dashboard is pretty cool, but it eats a lot of memory. If you want to disable it, execute this at a command prompt:

defaults write mcx-disabled -boolean YES

I did this but I’m also going to try to upgrade my PowerBook from 512 MB to 1024 MB, because a lot of OS X processes use a lot of memory and I don’t think that 512 MB is enough for a power user.

Podcast about Palm development tools

I’ve been toying with the idea of writing a Palm app or two lately so I enjoyed the last few minutes of this PalmAddicts podcast, where Tyler Faux talked about some Palm development tools such as Palm OS Developer Suite (PODS), PDA Toolbox, and Handheld BASIC (HB++). The first 15 or so minutes cover stuff about new licensees and the rumored upcoming Tungsten 7 which I wasn’t that interested in, but the last few minutes might be interesting to you if you’re thinking about doing some Palm development.


Skyped out

I hadn’t talked to my parents in a while and I had some SkypeOut credits and I wanted to test out my new Cardo Systems scala-500 Bluetooth headset:

I easily paired the headset with the Linksys USBBT100 Bluetooth USB dongle

plugged into my PC and configured Skype to use it.

Sound quality was fantastic and it was really nice to talk with the wireless headset. I still have 09.52 EUR left in my SkypeOut account and I will definitely be using this for future calls, since at 1.7 Euro cents (roughly around 2 U.S. cents) per minute, it is much cheaper than my AT&T long-distance phone service.

This was on Windows – maybe next time I’ll try to use the headset with the built-in Bluetooth in my PowerBook and see how that works.

Bulk renaming of files using regular expressions

This nice little Perl script is the most logical way that I’ve seen to rename a bunch of files. Well for UNIX/Perl geeks at least. You use nice little Perlish regular expression replacements to do the renaming. E.g.:

ren-regexp 's/JPG/jpg/' * (broken)

As pointed out by Jud, here’s another tool, which offers some additional features:
