Any graphql library would work. I like async-graphql except compilation is a bear due to all the macros. We wired LISTEN up to subscriptions using tokio mpmc channels. It was a gre…

Just sharing a data point and experience. We had a lot of success with LISTEN/NOTIFY when we paired it with a Rust graphql subscription broker. 10s of thousands of subscriptions, b…

Just a set of things too minor to move off of it but annoying enough to not want to start with it. My list: No `explain (analyze,buffers)`. Instant DDL has some warts (e.g. fk, met…

I've always known how to do zero downtime migrations. The question has always been "Is the engineering cost worth it?" > It only makes backwards compatible deployments easier insof…

> perfect refactor-proof testing contracts are still usually pretty hard to design Not sure about hard, but definitely rare and we as an industry are under-skilled in these areas. …

That's not at all what I meant. I mean "We can't build X because our code structure makes that difficult" has an opportunity cost of the value of X. I don't think the future of dev…

I'm not talking about time. I'm talking about safety. The amount of times I've seen "I refactored it, but I'm not confident enough to take it to prod" is significant. Being able to…

The cost of restructuring has also gone down. The cost of shoring up behavior with tests ahead of a restructure has gone down because of AI. The cost of implementing a zero downtim…

MTP on a MoE is hit or miss. If you're bottlenecked on memory, MTP can increase the number of active experts (like any batch processing would), which can eat away gains from it.

Generation is basically just memory bandwidth math. Each token has to read all the active weights. I think that's around 40B parameters active. At a 4-bit quant that's 20GB. With 1…

My favorite lens on SQLite is that it is actually two things: 1. A robust durability implementation 2. A library of high performance data structure and algorithms The fact this it'…

I wonder how Sonnet vs Opus stacks up in a similar time-based comparison. How far behind are open models compared to Sonnet? It may be that the absolute SOTA models are way ahead o…

I'm running opencode with qwen3.6-35b-a3b at a 3-bit quant. I also have qwen3.5-0.8b used for context compaction. I run with 128k context. It's usable. I set it loose on the postgr…

I have some experience in this. Reach out (email in my bio) I would love to chat.

Long agent runs make such a difference. We focus a lot on new models and long context, but the bigger impact is in automatic verification. I've been leaning in more on e2e test sui…

Gemma4, qwen3.6, deepseek v4, mimo, glm 5/5.1 all do MTP.

From the same org as pgrx is https://github.com/pgcentralfoundation/plrust , which _is_ supported on RDS (but not Aurora). Since it's a procedural language, you can't do things lik…

I've definitely done some vibe-coding with the explicit intent to reduce memory usage.

The announcement was that it secured $50M in financing, sold the shoes business for $39M leaving $20M or so in cash. An empty public company with $70M in financing to enter a hyped…

Given the premise that zero day exploits are going to be frequent going forward, I feel like there is a new standard for secure deployment. Namely, all remote access (including ser…

Isn't this just a SPAC? The shoe business was sold, a shell of a public company was left, and it essentially acquired a brand new company focused on AI.

I just got it last week. Still a few quirks, but positive so far.

I dropped my MBA on concrete and the edges got dinged up and sharp. A bit of 220 grit sandpaper and all the sharp edges are smooth and it actually looks pretty cool. I was grimacin…
