Progress, of a sort.

I fixed yesterday’s problems with the machine locking up every time I tried to burn a DVD by opening up the case and reseating all the cards and cables. Yeah!

Last night I worked on setting up a new computer for the flying club’s ops center. The old one started freezing up and dying about a month ago, and so I took it home to work on, and then never had time to work on it because of the move. Even after reseating everything and cleaning, it still freezes up after a few minutes of operation – it continues to work and the screen refreshes, but it no longer responds to the keyboard and mouse. A club member donated a machine which was even slower than the original (400MHz versus 550MHz) and has less ram (384Mb versus 512Mb). But it’s adequate. I installed Morphix Linux on it, which probably isn’t the best choice but it uses XFCE4 as its user interface unlike most small Linuxes that use IceWM or Blackbox or Fluxbox, which look like somebody with really bad colour sense and latent depression tried to copy the worst features of Windows 95. XFCE4 uses a Mac OS X-like application dock, and uses bright pastel shades so that it looks like something out of this century. The ~/Desktop/Autostart directory contains a script to start up Firefox with a special home page with some links that I find useful.

I stripped the stuff that users shouldn’t be doing off the menu bar, and set it up in /etc/init.d/xstart so that when a user logs out, the user’s home directory is blown away and re-copied from a read-only file system “safe”, and the display starts again. That way nobody has to worry about any of their web cookies, passwords or other cruft being left behind. And because it’s Linux, I don’t have to worry about them installing stuff or getting viruses or spyware.

I went for a little flight today

I haven’t been flying in a while so I went out for a aimless wander around. I noticed the landing light was out before I left, but I’m bad so I didn’t deal with it until I got home. I’ve never changed a landing light before, but I did it. Not exactly Tina Marie level of owner maintenance, but I’m proud of myself.

I’m back up, I think

After the hard drive problems I mentioned in a previous blog entry, my new hard drive arrived, and today I actually had time to install it.

I partitioned the new drive like the old drive, but with bigger partitions (because this was a 160Gb drive instead of an 80Gb drive). Being old-fashioned, I used fdisk instead of whatever the young kids use (parted?). Then I booted with a rescue CD and did the following to mount and copy all the partitions:

for i in 1 2 3 5 6 8 9; do
mke2fs -j /dev/hdb$i
mkdir /mnt/hda$i /mnt/hdb$i
mount -t ext3 /dev/hda$i /mnt/hda$i
mount -t ext3 /dev/hdb$i /mnt/hdb$i
rsync rsync -aSuvrx –delete /mnt/hda$i /mnt/hdb$i
done

Then with everything copied over and swapped around the drives and attempted to boot with the new one.

Ok, how many people spotted my deliberate mistakes?

First off, I forgot to install grub on the hard disk. So I had to boot back with the original drive as hda and the new drive as hdb. I couldn’t get grub-install to even recognize /dev/hdb or hd1. So I went into the raw and wolly grub shell to do it.

Second mistake was that I forgot my /etc/fstab uses labels. So I had to quickly google how to put labels on the partitions using e2label. But I couldn’t figure out how to label a swap partition, so I changed the swap entry in /etc/fstab to not use labels. Not sure why I didn’t just convert them all to not use labels, but I’m trying to be a little more modern.

Third mistake was that somehow /tmp ended up not globally writable. I think all the other files and directories had the right permissions, so I’m not sure why that one was different. Probably because it’s the only partition whose top level is globally writable.

Everything seems to be working now, so my fingers are crossed.

Paddle softly, and carry a light stick.

After Saturday’s paddling with Rob, he decided to buy the Tampico XL. Tonight was his night to pick it up, so we agreed to meet at Baycreek and break the new boat in.

When I got there, he was getting fitted out with paddle and PFD. He got a really nice PFD – one of the triangular ones that give you lots of room around the shoulders. Much nicer than mine. He also had a very light paddle with a carbon fibre shaft and composite blades. Extremely light, with a blade shaped for high angle paddling (which is my style). I figured it was about a $250 paddle. He said it was used, and he was getting it for $80! I was jealous as hell, especially since there was no visible sign of it being used. But the guy behind the counter corrected him – he said it was $80 off, and so it was $160. Rob recoiled visibly, and started to put it back on the rack. I quickly grabbed it for myself.

I took my old paddle and broke it down and slipped it under the straps on the back of the kayak, and went out for a spin with the new one. The more agressive blade shape meant that every pull rocketed me forward far more than the old paddle. And the lighter weight meant that I could paddle harder for longer.

Rob and I paddled for about two hours, up almost to Browncoft and back. His kayak seems as good as the Merlin he tried on Saturday when it comes to ease of paddling, but maybe with a bit more initial stability. It also seemed like it might be a bit easier to turn, without a pronounced keel line and a bit more rocker. He seemed very happy with it, and I think it’s a good choice for him.

I was very very happy with my new paddle, too. At the end of the hours, it still felt light in my hands, and two quick strokes would get me up to a breaking wake on the bow. I had lots of energy at the end.

Everybody in Rochester owes me money

Last night, a big storm ended a very long drought. Today the temperature is down under 70 degrees, after weeks up over 90 with high humidity. And you want to know why? Because today Taylor Heating came and installed central air conditioning in our new house. I’m predicting that the temperature will stay low for the rest of the year.
