iPhone photos ahoy! Another one! This time just because the light was so amazingly perfect that I had to take a picture of *something*. I wanted to see how the iPhone camera would handle the branches and tiny twigs with this type of light on them. Turns out, pretty darn well. Almost but not quite as well as, I would say, a 2002 era APS-C digital sensor. Which is damned impressive, considering that the entire camera is a 6mm cube that fits inside a mobile phone.

100% crop of the twig detail

It's very noisy though. 100% crop shows just how noisy this sensor is, even being back-lit and shooting at ISO 50. It's the sort of noise level that, given the good light, I would expect to see at about ISO 400 on an older sensor, and ISO 1600 on a modern APS-C SLR.

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.
