I’ve been waiting for the flying cars promised to me as a child. In the year 2000 you will have… Well it’s finally arrived: The flying car goes into production. For the record, I’m happy to wait at home on the arranged day of delivery.
Disks are the most unreliable part of any computer system. They fail reguarly and one did on me today. Thankfully I have a RAID5 system which means that I’m able to run with only 3 of the 4 disks avaliable. Still it’s not a nice situation to be in. I’d been watching the disk scream that it was having problems for the last 6 months. Well today it died. I swung by Bauers and picked up a new one, partitioned it to the same size and it’s currently rebuilding:
Personalities : [raid1] [raid5] [raid4] [linear]
md1 : active raid5 sdc2[4] sdd2[0] sda2[2] sdb2[1]
1142582400 blocks level 5, 128k chunk, algorithm 2 [4/3] [UUU_]
[>....................] recovery = 1.0% (3875840/380860800) finish=130.3min speed=48193K/sec
Moving parts suck.
For the record it should be noted that bunker.imaginator.com was running continuously for the last 210 days.

This is very cool: Context Aware Image Re-Sizing allows resizing of images by selective ‘distortion’ as an alternative to design-time choice of crop or scale.
It’s disconcerting to watch parts of an image disappear as it shrinks and purists may object but it does make sense in this ‘good-enough’ web 2.0 age (rather like lossy compression of audio has an application).

I’m impressed at how the different mapping services are democratising spying. Now the armchair spy can compare propellor sizes. The latest has maritime buff Dan Twohig catching Navy with their propeller’s pants down. And it’s a big one.The full story is on Ogleearth.com.

I setup some more monitoring of imaginator.com related servers. If you are interested the graphs of system performance reveal some interesting trends. I know that I’ll sleep better tonight knowing that we have enough entropy being generated. Please don’t use it all up.
Yes, the comment is tongue-in-cheek but entropy is an important component of a unix system. It’s read from /dev/random or /dev/urandom (for slightly more random data) and used in any application that needs a random seed, particularly cryptographic tools or games. Systems lacking enough random data would use a dedicated hardware random number generator, or in the case of the Commodore 64, use the built in random number generator. The C64 really was way ahead of its time.
Next week I’ll be looking at how one resolves excess mutex locks using a /dev/null accelerator.

[[post-media:FpEAmaBqyAekqIjzgtId]]I have a new GPS that attaches to my mobile phone. It’s quite good at logging routes although got a little confused when I had it in my pocket and under dense tree cover. The shown route is almost exactly 10km.
