A screenshot of Microsoft Notepad containing the contents of an email to the Chair of Aston Villa. The email, abbreviated, reads: "My name is John Greenfield, and I am writing to you not only as a lifelong supporter of Aston Villa, but as the great-grandson of Trevor Gill, who proudly served this club as its President. I am writing with a profound sense of duty to the club's history and its standing in the community, a legacy my great-grandfather helped to build. It is from this perspective that I implore you to take immediate and decisive action to cancel the club’s upcoming UEFA Europa League match against Maccabi Tel Aviv on 6 November 2025. My family's connection to this club is built on a foundation of integrity and community spirit. It is heartbreaking to see the club’s name associated with a fixture that presents a clear and present danger to our city and sanitises the ongoing atrocities being committed against Palestinians. The arguments against this match are not abstract; they are concrete and local. I am aware that West Midlands Police and the Safety Advisory Group have already taken the extraordinary step of banning Maccabi Tel Aviv’s supporters from attending, citing "current intelligence and previous incidents, including violent clashes and hate crime offences." This official assessment validates the severe risks involved. The visiting club’s fans have a documented history of anti-Palestinian racism and violence, exemplified by the disgraceful scenes in Amsterdam last year. The decision to ban them confirms they are a threat to the safety and security of the people of Birmingham. As the current custodian of Aston Villa, I urge you to honour the club's legacy. Refusing to host this match is not a political statement; it is a moral one. It is a stand for the safety of our community, a stand against racism, and a stand for the basic principles of human rights."

Aiko's learning network engineering. She isn't very good, but she tries her best.

Inspired by yesterday's trip, I've decided to have a go at spoons carving. So far so good, although the cramps are kicking in

Visited the Centre for Alternative Technologies open day. Haven't been since September 1999 and I was so grateful to be able to visit. I have a photo of 11 year old me sat in the exact same seat. I'll try and find it

This has to be the most focused on a project I've been for years. Just a few more tweaks then I'll get a demo put up.

Just a small project I've been working on today. Impressed with the results so far, but time for bed.
A screenshot of a web app called Catalyst. It's on a white background with a very minimalist look. It reads: Catalyst Your Executive Function Assistant. Enter a prompt below. With an example prompt asking for assistance writing an email to the users boss asking for a raise. There's a grey results box below with some AI generated output describing how to go about writing the email.

24 hours later, but I've finally managed to get Ubuntu on this Mac Mini. Apple really goes out of their way to stop you doing this.
