PgDog | Founding Software Engineer | Remote & Onsite (SF) | Full time | https://pgdog.dev PgDog is a proxy for scaling PostgreSQL, the world's most popular open source database. Co…

There is a difference between using an electric drill and having a robot assemble the entire car.

Yup. Getting pretty tired from seeing these "0days" that are not exploitable in any real use case. Just vibes, no substance.

Kagi is amazing. Worth the subscription, 10 times over. I don't have to worry about sponsored search results, or slop from the "AI overview". High quality results, like Google used…

This is nonsense. Tokio was built for I/O, not crunching numbers. Most programmers know to use spawn_blocking to crunch 10MB JSON, if needed. Additionally, the proposed workload pe…

I think most tools, according to the UNIX philosophy, do one thing (and do it well). AI is a tool that does _a lot_ of things...to various degrees of success. While you can verify …

Should HN add the ability to flag articles as AI-generated? This doesn't have to act as a regular flag, i.e., it won't de-rank the article; it could just show up as an indicator, a…

Glad you like it. It was built to fix some of PgBouncers shortcomings that we ran into at Instacart many years ago, and to have a stronger foundation for scaling Postgres horizonta…

Ouf. I don't know. I don't want to call you out without evidence -- I myself make benchmark claims all the time -- but 50% improvement in OLTP seems suspicious. I get that you used…

Pin the client temporarily. I'm assuming that our users know what they are doing. I could be wrong, but so far so good.

Yes. The plugin architecture supports this currently. That being said, you can use any number of sharding functions we support to do this too.

Thanks! We try to be very open and explicit about why we chose AGPL. Personally, I like it because it's an extension of GPL, which is a huge reason why I was able to self-teach pro…

Handling cursors is tough - they are very much session-level objects, so even if we, say, pinned your client while it uses that cursor, which would work, that would decrease the pe…

I don't think so. Too much trouble. Caching is a really hard problem without context, and the context, typically, is app-specific.

From the strictest CAP theorem definition, that's correct, it is not. But, it's pretty close. I know that in the database world, that's not a good answer, but in practice, it will …

Very cool. At first, I thought it was yet another LLM-generated demo, but no: original work of art. Super cool. Transpiling into C does seem easier than LLVM IR, and letting GCC op…

I cancelled Claude. The harness is kinda broken, GPT 5.5 is good, and GLM 5.2/Deepseek is good too (with pi, especially). Just not worth the trouble. And I'm not going to pay two s…

CRUD apps don't usually delete in bulk. It's also hard to structure partitions in a way that doesn't wipe out months of important business data -- this is why teams often ETL their…
