作者回顾2025年个人经历，包括大部分时间受竞业限制、新工作，以及制作视频和参加会议演讲等，并在文末说明细节。
Written by me, proof-read by an LLM. Details at end.
2025 has been quite a year for me. The big ticket things for me were having the majority of the year on a non-compete, a new job, and some videos and conference talks.
It was a bumper year for my public talks, which included:
- ACCU Keynote - Teaching an Old Dog New Tricks
- C++ on Sea - a reprise of the above talk, slightly shortened
- CppCon Keynote - C++: Some Assembly Required
- Jane Street - Microarchitecture: What Happens Beneath
I also appeared in a number of Computerphile videos:
- Computer Timescales Mapped onto Human Timescales
- How CPU Memory & Caches Work
- Subroutines in Low Level Code
- CPU Interrupts
- CPU Kernel Mode
- Memory Mapping
- CPU Summary
- What is Bootstrapping Anyway?
- How Computers Store Data Serially
- How Ethernet Sends Data
On the Compiler Explorer front, I finally solved a three-year-old problem with CEFS — our new content-addressable filesystem that mounts compiler images on demand instead of all 2,000+ at boot time. I also launched the experimental Claude Explain feature during my CppCon keynote, and wrote about how CE works and our cost transparency. As always, CE is a community effort and I’m grateful to all the contributors who keep it running.
Ben and I kept up our monthly Two’s Complement podcast, releasing all 12 episodes on schedule. Highlights included pondering AI pair programming, debating C++ and Rust, worrying about vibe coding replacing junior developers, and bonding over Factorio.
I ticked off a bucket list item by appearing in a Tom7 video, alongside such greats as Matt Parker and jan Misali in a bonkers Secret Santa video. Such fun, and thank you Santa for my very awesome comic book.
Finally I had my very own series on YouTube - the Advent of Code Optimisation - 27 videos in all. That was a huge amount of work: with the blog posts, filming and editing I estimate I spent around 10 hours on each 5-10m video!
A very busy year, ending with me starting work at Hudson River Trading. I’m only a month in, but I couldn’t be happier with my decision to work here: it’s a fantastic place full of impressive technology, interesting problems, and perhaps most importantly, kind and thoughtful human beings.
Here’s to whatever excitement 2026 will bring! Happy New Year everyone!
