Coding Agent VMs on NixOS with Microvm.nix
I have come to appreciate coding agents to be valuable tools for working with computer program code in any capacity, such as learning about any program’s architecture, diagnosing bugs or developing proofs of concept. Depending on the use-case, reviewing each command the agent wants to run can get tedious and…

4x faster network file sync with rclone (vs rsync) (2025)
For the past couple years, I have transported my 'working set' of video and project data to and from work on an external Thunderbolt NVMe SSD. But it's always been slow when I do the sync. In a typical day, I may generate a new project folder with 500-1000 individual files, and dozens of them may be 1-10 GB in size…

Is the RAM shortage killing small VPS hosts?
The AI surge has DRAM producers like Micron focus on HBM (High Bandwidth Memory) to serve AI hyperscalers over the DRAM (Dynamic Random Access Memory) used by ordinary consumers and small businesses. Consequently, for instance, servers which used to cost $2500 on Newegg now cost $5000. RAM alone is $2500 now.

The future of software engineering is SRE
When code gets cheap operational excellence wins. Anyone can build a greenfield demo, but it takes engineering to run a service.

Provide agents with automated feedback
Back pressure for agents You might notice a pattern in the most successful applications of agents over the last year. Projects that are able to setup structure around the agent itself, to provide it with automated feedback on quality and correctness, have been able to push them to work on longer horizon tasks. This…

I hate GitHub Actions with passion
I can’t overstate how much I hate GitHub Actions. I don’t even remember hating any other piece of technology I used. Sure, I still make fun of PHP that I remember from times of PHP41, but even then I didn’t hate it. Merely I found it subpar technology to other emerging at the time (like Ruby on Rails or Django). And…

I’m leaving Redis for SolidQueue
Rails 8 eliminates Redis from the default stack. Learn how SolidQueue, SolidCache, and SolidCable replace Redis for job processing, caching, and real-time updates—powered entirely by PostgreSQL. Explore the true cost of Redis, how SolidQueue works, when it scales, and how to migrate from Sidekiq to a simpler…
