In case you're not aware, there's COVID-19 happening! Here's some stuff we wrote that you won't read.

GLM-5.3: Frontier Coding with Emergent Cyber Capabilities

Scaling post-training is all we did for GLM-5.3. With GLM-5.2 we built the stack: IndexShare for efficient long-context processing, SAO for RL on long-horizon tasks, and slime for large-scale asynchronous training — all running on the long-horizon task environ…

Understanding is the new bottleneck

Agents can write code faster than we can absorb it. Here's why it still matters for humans to understand what they build — and some techniques for doing that efficiently: explainer docs, quizzes, micro-worlds, and shared spaces.

Compute-Optimal Is Not Cluster-Optimal — Sheng Zha

Our new paper folds the systems stage into the scaling-law stage. Price every candidate architecture on what the cluster actually delivers, and the answer changes: the sparsity an MoE 'should' have depends on the cluster you train it on.

I want extern "fil-c"

Compile legacy C with Fil-C, call it safely from Rust, and make runtime checks the tax for not migrating the hot path.

Choose Boring Technology

Probably the single best thing to happen to me in my career was having had Kellan placed in charge of me. I stuck around long enough to see Kellan’s technical decisionmaking start to bear fruit. I learned a great deal from this, but I also learned a great deal…

30× faster binary multivector ColBERT late interaction in Vespa

A key advantage of Vespa against other search databases is the ease with which you can index multiple chunks of a long document in a multi-vector fashion. This is convenient in RAG applications as it allows your overall document score to be an arbitrary score …

Our latest OCR service powering our Document AI stack, with native paragraph-level bounding box extraction, structural block labels, and block-level confidence scores.

Move FreeBSD System Between ZFS Disks

I made a funny mistake in one of my clients when installing FreeBSD 15.1-RELEASE on their server … I have chosen wrong disk for the installation. The server had 4 local disks – 2 of the…

Hello, me. It’s been a while. - The Mech - programming blog

Wow. It’s been over fourteen years since the last time I wrote a post on this blog. In those fourteen years, the world has changed, and so have I. So this isn't going to be a technical post, it's going to be personal. One of those subtle changes that quietly c…
