I left my iPod Shuffle in my car all day today, connected to my car stereo and playing (although the car stereo itself was off of course). It still had enough power to provide me with music all the way home, which means it lasted at least 8 hours (it wasn’t fully charged this morning). I’m currently listening to iTunes on my PowerBook, and it is using between 10 and 15% CPU. This obviously runs down the battery in my PowerBook. Itunes Cpu Usage Why can’t Apple “build” an iPod shuffle into the PowerBook? It could connect to the USB bus internally, and all it would need is a kernel driver to control it, that iTunes could use to tell it to play a particular track. It would free up the system CPU to do other stuff, and extend the life of the battery.

I bought a book called “Getting Things Done” by David Allen. It arrived on Monday. I haven’t had time to read past the prologue yet. Happy New Year, by the way.

Mac OS X 10.4 comes with ruby 1.8.2, it seems to have a problem with OpenSSL which causes
1
switchtower
to hang when trying to connect to your server. You can download the source code to Ruby 1.8.3, compile it and install it, but you’ll start getting weird errors in
1
gem
when you try to install some libraries. The solution turned out to be to compile Ruby slightly differently. You need to pass some flags to configure:
1
./configure --enable-shared --enable-pthread
After configuring it,
1
make
ing it, and running
1
sudo make install
, I had what seemed to be a working Ruby installation. It installs to
1
/usr/local/bin
which is already in my path. Executing
1
hash -r
causes
1
bash
to re-scan the path, after which executing
1
ruby -v
correctly reports
1
ruby 1.8.3 (2005-09-21) [powerpc-darwin8.3.0]
After that I installed RubyGems-0.8.11 and the
1
rails
and
1
switchtower
gems, including all dependencies. The installation worked fine, and so did
1
switchtower
when I tested it. I didn’t even need to remove Apple’s Ruby install. If you do want to remove Apple’s installation of Ruby, you’ll want to back up and delete the following files and directories:

I’ve got some new glasses! I had my eyes tested in August, and the prescription had changed so little I didn’t fancy spending £200 to replace my old glasses (which I’d had for nearly 3 years). Then about 3 weeks ago, I was using my PowerBook in bed (calm down at the back there! I was designing a website…) and I realised I’d misplaced my glasses. I found them under the PowerBook, with the lenses scratching against the underside. The left lens picked up a big circular scratch almost exactly aligned with the centre of my eye.

Conversation at our house earlier today: Heidi: I’m just going to buy some milk from the shop over the road
James: Why?
Heidi: Because daddy’s going to do some cooking
Matthew: What’s he making?
Heidi: Well, what’s the only thing he knows how to cook?
James: Pancakes!
Matthew: Tea!
Me: What? Cheeky little… I have a bigger cooking repertoire than just pancakes and tea!
James: [after a perfect comedic pause] …coffee…
