Hardware

This page contains a range of hardware monitoring metrics and other data about each of the computers that I maintain. Almost all of this data is redacted on the public version of this web page, but I've added photographs and descriptions of each of the machines.

Current workstation. It uses much less energy than any of my previous builds, and delegates a lot of work to intermittently-powered servers.

This enourmous pink cube got me through most of my PhD. It used to be water-cooled and exceptionally powerful; I treated myself to the pink case to celebrate the end of my second Google internship. Over the years, it's become less necessary to have such a power-hungry machine switched on all the time, so I now use it for more specialized and intermittent services.

gurnard once belonged to a postdoc at Queen Mary University of London, who absconded with it when he moved to UCL. I inherited it from him when he left to greener pastures; it's currently a server, using mostly scavenged parts. It still has the white QMUL CS department sticker on the front.

This was the first PC I ever built! I was quite excited about installing and using Arch Linux on this machine, so I used a Dremel to cut a Tux logo out of the side of the case. I was unfortunately careless, and so the penguin is...upside-down. Tux is illuminated from behind, similar to the Apple logo on old Mac laptops, and I used yellow Quality Street candy wrappers to colour in the beak and feet. This machine was my workstation throughout my undergraduate days. It has fairly modest energy requirements, so I currently use it as a server.

I had bought myself a new Lenovo E540 before starting my PhD, which proved to be highly unsatisfactory. I put that machine's SSD into a second-hand X230, which served me well through most of my PhD. This was the last model of ThinkPad X-series to have the cherished prominent hinges, high-quality trackpad with physical buttons, and various other important features. Lenovo has been slowly ruining this series of laptops for years.

This was the first MacBook Pro to have a unibody design, and the last major model to feature a matte screen. It was easy enough to disassemble that I was able to pull the screen out of the lid and colourize the Apple logo in the 1977 colours, using strips of Quality Street candy wrappers. There are stickers that can be applied to the glowing Apple logo to achieve a similar effect, but my version was invisible when the screen was switched off; the colours would magically appear when the screen's backlamp was illuminated.
