I agree, I too found this barely readable. Interestingly, ChatGPT was able to parse and explain it to me. I got a lot out of its presentation.

I get it. But I never would have until I built muscle memory for the keyboard shortcut.

I see JSON parse errors on occasion when using OpeanAI structured outputs that resolve upon retry. It seems it’s giving instructions to the LLM but validation is still up to the ca…

We've been focusing on indexing but query rewrites are probably next. It looks like LLMs can do a pretty good job at generating ideas, particularly if you prompt them right. After …

Right. Why build another MCP server for Postgres? There's a lot of value in just getting a database connection. But the LLMs hit limits pretty quickly when it comes to index tuning…

Hey HN, Postgres Pro is an open source Model Context Protocol (MCP) server built to support every stage of the development process. It does a lot more than help generate and run SQ…

Confused about the new US tariffs? We built an interactive US Tariff Calculator—a simple tool to help you instantly calculate the new tariffs per country.

Yes, but it is more restrictive, e.g., it is not Turing complete. I’m not sure whether this directly addresses Spectre risks though. An analysis of Spectre and software isolation i…

Fair enough. American companies (and people) definitely have a home bias. I guess to be constructive, I would suggest that perhaps there are parallels in your country.

I don't remember exactly how it broke the first time, but the cognitive overhead shows up in various places. E.g., start a new project, create a branch, then merge back to master..…

I want to share my own reactions to the name change since this is a really interesting topic. For context, I'm an African American, so many of my ancestors were slaves. - The first…

Yes, the idea is that the cloud provider should offer something like this. We intercepted system calls to simulate what it would look like.

Thanks for sharing your writeup and the potential use cases therein. We've been building an experimental shared file system that specifically targets the FaaS setting. It supports …

Would any of these be useful for working with Johns Hopkins Covid-19 data? There are some web interfaces but analyzing and visualizing with Python would be more flexible. ( https:/…

This capability is compelling from a public-health standpoint but has serious privacy implications. It looks like every phone shares a unique id, but encrypts it in a frequently ro…

If you’ve used some heavyweight framework then performance will probably be hard to add later. If you wrote the code yourself then I’m with Knuth, it’s not a big deal to optimize i…

One startup that’s working on this is unitQ: https://www.unitq.com

I think this has been the case for the case for the past 20 years, probably longer, though I'm optimistic that improvement is possible. E.g., perhaps serverless computing is ineffi…

> Many researchers are now arguing that we should, more generally, move away from using statistics to make all-or-none decisions and instead use them for "estimation". In other wor…

This view on sharing hardware seems too pessimistic to me. Strong isolation should be achievable when it is the design objective and and priority. On the end-user/device side, Java…

As a command-line tool it could serve as a more powerful replacement for unix utilities that I often use for simple analysis jobs: sort, uniq, wc, awk, sometimes cut and sed. I'm g…

This is a really interesting comparison. Plumbing jobs have a reputation for high pay, as do jobs in tech. Is hooking up APIs as miserable as fixing faucets? Maybe, but I really th…

One reason why we should care about culture at other companies is because it drags down the appeal of our industry. When talented people with lots of options choose a career outsid…
