HP vs IBM Laptop Engineering

I have just had reason to open up two ageing laptops to retrieve their CMOS batteries. Here is a quick rundown of what I had to do to get to them.

HP Compaq Evo N115


What I had to remove:
  • Battery
  • Hard disk
  • CD-ROM drive
  • LED cover
  • Keyboard
  • Screen
  • Heat dissipator
Total screws: 19 T-8 head screws of varying sizes, including 4 sprung screws that have to be removed and replaced in a specific order to prevent the heat sink breaking.

Time to disassemble: 20 mins
Time to reassemble: 10 mins

IBM Thinkpad R30


What I had to remove:
  • Keyboard
Total of 2 Philips head screws.

Time to disassemble: 1 minute
Time to reassemble: 1 minute

Conclusion

I think the conclusion is fairly obvious. The R30 is a "consumer" level laptop, so doesn't have the shear awesome build of the T or X series Thinkpads, and yet even for something as simple as this it runs rings around the other "big brand" laptop I have the misfortune of owning.

Thinkpad. Because anything else is just a world of pain.

Fairy Lights

Street lights at night can be very pretty. For someone who lives close to the centre of a large city, skirting round the edge of the town centre can provide a host of beautiful views at night. One advantage to using a wide open lens when taking these pictures is the capture of bokeh, or creative blur. An extreme example is shown to your right; a mass of coloured circles that roughly represent the city they are part of. A more subtle example, of course, is in the picture of the day at the top of this post. The lights cluster around the top of the leaves like fireflies, obviously part of a cityscape but at the same time abstract. The extreme out of focus image is a blurred version of the picture on the left. A view over Sheffield from Pitsmoor, looking up Netherthorpe Road and up to the university. Even when the buildings are focussed (roughly; I'm still practicing) the lights take on the shape of the lens's aperture. I try to incorporate some foreground focus wh...

In which I complain that coding standards are a waste of time

Just kidding. I'm not going to rail against coding standards. No, I'm going to rail against the absolute and dictatorial enforcement of coding style guidelines, to the point where a single misplaced curly bracket can fail the code review of a thousand line project before it's even started. I'm going to rail against the fact that many people these days don't actually know that coding style guidelines and coding standards are not the same thing. Coding style guidelines are not coding standards. Coding standards are rules on how to construct software. Rules that have practical and defined benefits. Rules than can be proven to assist in the structured and correct building of code. For example: Do not perform database access in the constructor. All database access should use the framework's DAL. Do not rely on complex instantiation instructions; provide a factory method. Do not inherit from a class in a different module or library; only encapsulate. Avoid sin...

DeCSS on Ubuntu 9.10 and later

It used to be the case that enabling DVD playback on Ubuntu was a case of installing ubuntu-restricted-extras and that was that. Unfortunately DMCA nonsense in the US has buggered that up for all of us and so now there's an additional step. So, without further ado, here are the commands that need to be run at a command line: sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh Voila! DVD playback a-la Ubuntu.
