recently Qwen3-Next-80B-A3B has become my goto model for asking "how-to" questions in the work. it's not considered as a smart model but it's really dog fast 😲

yeah, it's an optimistic numbering scheme, if there's any username conflict, I'll just back off to the next year and try to register the account again. 😂

what an amazing journey! after working through this step by step, we finally have a functional transaction API with SSI support. hope it proves useful! 😁

SlateDB has transactions. A year in the making. Lots of testing to do, but the APIs are there. This was all @flaneur2024.bsky.social. 🙏 I am very excited about this feature.

You already know the answer, but it’s nice that someone put in the manual effort to create a benchmark

early return / goroutine leak is my favourite interview question, it can help reveal a candidate’s awareness of resource management, which is essential for building robust systems 😲

Regarding goroutine & unbuffered channel interaction, found myself repeating this multiple times. Maybe it's time to write it down for reference.

Early return + unbuffered send = goroutine leak.

Early return and goroutine leak

At work, a common mistake I notice when reviewing candidates’ home assignments is how they wire goroutines to channels and then return early. The pattern usually looks like this: start a few goroutin...

2/ Snapshot isolation — @flaneur2024.bsky.social has been hard at work on snapshots/transactions. 0.8 now has `DbSnapshots`, which provide a consistent point-in-time DB view. Sequence numbers are now core to SlateDB and will be used for many features (including transactions) going forward.

instead of just looking at scores, we can build up an internal 'reputation' for each model based on how it performs day-to-day 🤔

flaneur2024.bsky.social @flaneur2024.bsky.social · Sep 7

it seems there's no gold-standard benchmark for coding models at the moment. imho, the only way to know if one is any good is to throw a (real world) task at it and see if it can handle it smoothly 🤔.

in the age of vibe coding, the measure of a top programmer should be how long they can get Claude Code to work continuously without human intervention. if you can get Claude to code independently for a full 24-hour workday, you deserve top dollar in the market 🤔

I went through DuckDB's WAL, and it does everything I was asking for in my blog post:

1. Per record checksum
2. Explicit error on checksum failure
3. Configurable behavior
4. Partial recovery
5. Safe truncation of the WAL only when WAL contents are checkpointed

Published a new post: "PSA: SQLite WAL checksums fail silently and may lose data"

This is a follow up to my previous posts. When SQLite encounters checksum failures in WAL, instead of raising an error, it drops all subsequent frames; even if they are not corrupt. It's not a bug

PSA: SQLite WAL checksums fail silently and may lose data

This is a follow-up post to my PSA: SQLite does not do checksums and PSA: Most databases do not do checksums by default. In the previous posts I mentioned that SQLite does not do checksums by default, but it has checksums in WAL mode. However, on checksum errors, instead of raising error, it drops all the subsequent frames. Even if they are not corrupt. This is not a bug; it’s intentional.

however, non-linear FFNs are terrible at learning the identity function. It's like trying to jump up to the 15th floor and then land back exactly where you started. with ResNet, the layer simply adds its input to its output, making the `identity` function trivial to learn 😲
