It appears that I've become rather busy at work, so I might not get so much time to write articles for the next short while. I'll still hope to put stuff up every couple of months, so keep an eye out.
- Ticketed
- 15th Mar 2017
- A long-awaited sequel to Prime Point, in which our brave protagonist finally jumps into a hyperspace-capable ship and ends up... somewhere.
- RFC 7168: Hypertext Coffee Pot Control Protocol for Tea Efflux Appliances
- 1st Apr 2014
- An update to HTCPCP (RFC 2324) to allow for the connection of networked tea-brewing devices. Published under the RFC Informational series.
- Let's Build a JPEG Decoder: Frames and Bitstreams
- 5th May 2013
- Continuing a series exploring the concepts behind JPEG image compression, this part begins delving into the relationship between the image, its colour constituents and the encoded data by breaking open the Start of Frame segment.
- Let's Build a JPEG Decoder: Huffman Tables
- 24th Feb 2013
- Various levels of compression and encoding are employed in the production of a JPEG file. The first step in decompressing an image is decoding the data, which is compressed with a variant of Huffman encoding. This article looks at the data attached to a JPEG file which allows the Huffman decoding to proceed.
- Let's Build a JPEG Decoder: File Structure
- 20th Jan 2013
- Aside from the concepts explored in the previous part of this series, the JPEG file format is composed of segments which encode the various portions of information needed to decode an image. This article implements a simple method of traversing the segments of a JPEG file.
- Let's Build a JPEG Decoder: Concepts
- 5th Jan 2013
- The JPEG image format is a bit of a black box for many: files go in and images come out. Looking inside the box reveals a bunch of interesting algorithms and ideas, so writing a JPEG decoder makes for an interesting exercise. This article explores the concepts behind the compression techniques used by JPEG.
- svn branchlist: Print branch name for multiple repos
- 3rd Oct 2012
- Ever run into a codebase with multiple Subversion repositories, where you just wanted to find out which branch they were all on without tediously cd'ing into each working copy? Try this script today, and make your life easier.
- How Emulators Work: a presentation
- 27th Jun 2012
- At deviantART's technology team meetup in France ('Breadlands 2012'), I gave a short Ignite talk distilling the first three articles in the Gameboy Emulation in Javascript series. The slides from that talk are now available here.
- Behind the Mirror
- 24th Jan 2012
- The day after the night before, a hungover flatmate notices that the wall mirror looks a bit strange. Speculative flash fiction.
- Steganography with Brainfuck
- 12th Nov 2011
- There are a number of techniques for encrypting or hiding information within an image, including the concept of hiding a program within the image which itself prints the secret information. This article explores the feasibility of encoding a Brainfuck program within the bitmap data of an image, with a detailed run-through of a simple example.
