Open Source After the Extraction โ€” jd:/dev/blog The old open source deal is dead. What replaces it isn't a fix, it's a transformation. Open source stops being a community and becomes a supply chain.

Thoughts & Links 14 Assorted thoughts, early 2026.

Just blogged: Thoughts & Links 14

Almost 100% agentic coding-related. As it should.

Yea, GLM 5 is probably better. OpenCode Zen often has very strong models for free, currently GLM 5, Kimi K2 and MiniMax M2.5.

Current free agentic coding setup: pi + GLM-5 on OpenCode Zen. I still use Amp too but the free credits don't last long so I keep it for the harder parts.

What percent wrong is the output of your colleagues? Do you check it more or less thoroughly?

The AI Vampire This was an unusually hard post to write, because it flies in the face of everything else going on.

For those who are already using coding agents 100% of the time or close, this is important: steve-yegge.medium.com/the-ai-vampi...

The "Claude as a pair" way to work is by far my favorite but it is not sustainable because of this. As models and agents improve we'll need to learn to really delegate.

Vibe-coded project of the day. Watch logs from modal runs & kill them.

Made with Teal this time, because agents can use languages they don't know much too. I have a real use-case for this, but mostly it was to test terminal.lua.

What I do at Finegrain What making lightweight image editing models that run on edge devices entails.

At each of the companies I worked for, I have written a blog post describing what I was doing there after a few years. In keeping with the tradition, here it is for Finegrain: blog.separateconcerns.com/2026-02-07-f...

Several of the best engineers I know have joined the performance teams of Anthropic and OpenAI. They are probably part of the few teams with the highest concentration of talent in the world by now.

Haven't tried either! Just read stuff / watched videos so far. I want to, that's what I was saying above - but mostly because the spec mode intrigues me.

15.01.2026 11:33 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 1 ๐Ÿ“Œ 0

No I haven't either! I think it's somewhat similar in approach to the spec mode in Kiro.

I am curious about the specs part (also mentioned by @waxzce.org in his recent talk).

Currently with Opus + CC-like harnesses I found it better to iterate from simple prompts and not spec too much, but I will probably try a more spec-focused tool such as Kiro when I find time.
