“vWorkbench” is my own personal Vim9-based development environment and writing environment that I’m trying to ‘spin out’ into an open source project that is stable enough, reusable enough and well-documented enough to be used by others. https://github.com/wordswords/vWorkbench.git - this is the current version of my development environment that I use as much as possible, both in personal and work situations. https://github.com/wordswords/vWorkbench/blob/master/README.md - this is the documentation on my development environment, which I absolutely try and keep up to date. ...

I am currently familiarising myself with tools to implement cyber security solutions. This is in preparation for my research project as part of the MSc Cyber Security masters I’m taking from the University of London via distance learning. This research is strictly for informational purposes and I don’t do anything criminal with it. I realise some of this information may be seen as ‘over-sharing’ and is a security risk in itself, but I believe that the benefits of sharing this information outweigh the risks, and that there is no ‘security via obscurity’. ...

I use this setup, along with my bike to work from wherever I want. It does kind of turn heads, and I’m aware it may look a little ‘over the top’ - but it’s a very useful setup for me, keeps me healthy, and fits all my requirements. Hercules DG400BB Laptop Stand w/ Bag - this portable laptop stand is very sturdy and is designed for mobile DJ use. I find it is excellent in all situations, not just DJ use.

Logitech MK295 Silent Wireless Mouse & Keyboard Combo - This is a good mobile keyboard and mouse setup, which I got because I was making too much noise typing at ~100wpm in libraries. Portable Battery charger - A good quality external battery charger which will charge and release charge via USB A and USB C ports Lenovo Legion 17" Armored Backpack II - This is an excellent quality padded laptop bag - by far the best laptop carrying case I’ve owned. It distributes the weight of my setup properly over my back so I can walk long distances Sony Xperia 1 V Android mobile - This is a top of the line media phone which I’ve had for a while now and am very happy with. I often use it as a mobile hotspot for the laptop. It is waterproof. Sony MX1000 Mk3 wireless headphones - This is a top of the line HDAC/Apt-X HD wireless noise cancelling headphones. They work well with my laptop and my phone. Rock Cloud Portable Camping Table - This table will hold up to 25KG which is more than enough for my laptop setup. LUXJET Portable Folding Stool - this telescopic stool is rated up to 180KG and is very compact when folded up. 750ml vacuum thermos flask - This fits in a pocket on the side of my laptop bag, and is usually enough unless it’s a very hot day. Pro-plus caffiene pills - My lifestyle means I am tired sometimes, and I don’t drink tea or coffee, so I always keep some of these in my wallet if I need to walk home, for example. SanDisk 1TB Extreme Portable SSD, USB-C USB 3.2 Gen 2, External NVMe Solid State Drive - This is very useful for transferring large file collections to and from other peoples computers, and is very small for carrying. Fasgear Cat 6 Ethernet Cable, Retractable Network Cable 10Gbps - If I ever need to connect to a wired network, I can use this network cable - it takes up very little space. Octopus style USB cable adaptor - Can be used for any connection between standard USB A, USB C, micro USB and lightening. It’s very useful for connecting to other peoples devices. USB C privacy guards - Allows me to plug into a USB C port and block data transfer, so I can charge my phone from other peoples computers without worrying about data transfer.

I have a fibre to the house 2Gb/sec connection provided by BRSK , who I really recommend. This means that maximum download speeds are 250 megabytes per second, although often this is throttled at the source level. My home network routes at around 2-4gbit/sec between 10gbit/sec DAC fibre connected hosts, and around 2gbit/sec via CAT8 for Thunderbolt 2.5Ggbit/sec laptop network interfaces.

We have a Phillips Hue light source setup, with 5 Hue lights in the Music Studio/Games room, which I set to strobe to music when I do my DJ sets, and setup as a Hue Entertainment Area when I play games/watch films. I also have Hue lights in the study and my bedroom, with dimmers etc. We have a robotic vacuum cleaner which helps Conny around the house. We call it ‘Dusterbuster’. Wherever possible, all devices have a wired network connection. Wireless is only used as a last resort, to minimise spectrum interference. We use ZeroTier as a VPN so that everything useful is accessible outside the home. My home server runs about 14 docker containerized services of different types, using docker compose. I self-host my own websites (including this one), and a bunch of other services for my friends and family. See my media library homepage which is a kind of ‘intranet homepage’ for my network. ...

Currently as of 25/5/25: I am DJing every Friday at around 11pm time on Heavy Resistance Aberdeen which is a rock and metal Twitch DJ Stream, with Mark Chalmers and friends. Audio and music has always been a big part of my life, which I used to actively pursue in the evenings while working in software/IT. I have DJ’d semi-professionally, with stints in club residencies, mobile DJing and Twitch DJing, for over a decade. I also produced and released several electronica albums. I have done paid freelance work on sound design and studio building. I studied the core parts of a Bachelors degree in Sound Engineering and Music Production, as a distance learning course while I was working full-time, at the excellent Point Blank Music School in London. I have also done a lot of self-study in music theory, sound design, and audio engineering. I am not currently putting as much time into music as I would like any more, because now I’m in my 40s it has been difficult to keep ‘burning the candle at both ends’. However I still enjoy playing my synths, live music, and listening to music on my custom listening setup. ...
