Intel Finds Great Performance With PostgreSQL’s AVX-512 Support
Back in April PostgreSQL added AVX-512 support for CRC32 computations. At the time the gains for CRC32 computations with this popular open-source database server were reported to be 50% to 3x faster for x86_64 CPUs able to leverage AVX-512. That AVX-512 support is found with PostgreSQL 18.0 that released in September and now Intel is praising this addition to PostgreSQL for which their developers also had a part in along with AWS and others… ⌘ Read more
Intel’s Rewrite Of Linux MM CID Code Showing Some Nice Gains For AMD
Posted last month were new Linux kernel scheduler-related patches rewriting the MM CID management code. The main takeaway for end-users from this set of 19 Linux kernel patches from an Intel engineer was seeing 14~18% improvement in a PostgreSQL database benchmark but that more benchmarks were needed. Curiosity got the best of me and I recently tested these patches on an AMD EPYC server to seeing some very enticing results for this in-development c … ⌘ Read more

Simple, minimal SQL database migrations written in Go with generics. Std lib database/sql and SQLX supported OOTB
I built GoSMig for personal projects and open-sourced it. It’s a tiny library for writing migrations in Go (compile-time checks via generics). Supports both transactional and non-transactional steps, rollback, status/version commands, and a built-in CLI handler so you can ship your own tool.

What’s your go-to strategy for giving engineers access to production?
I’ve been in this field for almost 15 years, and I don’t think I’ve ever seen two companies handle this the same way
Some other places just hand out just-in-time database access with short-lived credentials, others rely on rigid role-based permission, and others go all in on anonymized data dumps or shadow environments to avoid prod access altogether

Chances are the database bought wasn’t cheap at all and was aold by some scam company that probably ripped them from six figures or more for a database that’s full of rubbish. 🤣
Now that’s interesting. Some of these bots start crawling at URLs like this:
That is obviously completely wrong. But I can explain it. Some years ago, I screwed up my nginx rewrite rules, and that’s how these broken URLs came to be.
It all redirects to /git now, which is why that endpoint sees so much traffic lately.
But what does that mean? Why do they start there? I can only speculate that this company bought an old database of web links and they use that to start crawling. And it was probably a cheap one, because these redirects have been fixed for quite a long time now.
linode’s having a major outage (ongoing as of writing, over 24 hours in) and my friend runs a site i help out with on one of their servers. we didn’t have recent backups so i got really anxious about possible severe data loss considering the situation with linode doesn’t look great (it seems like a really bad incident).
…anyway the server magically came back online and i got backups of the whole application and database, i’m so relieved :‘)

Rather than maintaining a separate index or external database, VectorVFS stores vector embeddings directly alongside each file—turning your existing directory structure into an efficient and semantically searchable embedding store.

@kat@yarn.girlonthemoon.xyz yes, both the newsletter and the podcast, from time to time.
@prologic@twtxt.net I was not expecting much, but since the list of restaurants near company buildings, was hard coded into it, I did expect it to at least copy the menu text, from the websites, in its database. Ironically, the only restaurant where it got something right, is the only one, where the websites has the text as a transparent PNG, the AI has to convert to text.

I asked ChatGPT what it knows about Twtxt 😂 And surprisingly it’s rather accurate:
Twtxt is a minimalist, decentralized microblogging format introduced by John Downey in 2016. It uses plain text files served over HTTP—no accounts, databases, or APIs.
In 2020, James Mills (@prologic@twtxt.net) launched Yarn.social, an extended, federated implementation with user discovery, threads, mentions, and a full web UI.
Both share the same .twtxt.txt format but differ in complexity and social features.

@movq@www.uninformativ.de json and database put together sounds terrifying. i must try jenny
jenny really isn’t well equipped to handle edits of my own twts.
For example, in 2021, this change got introduced:
https://www.uninformativ.de/git/jenny/commit/6b5b25a542c2dd46c002ec5a422137275febc5a1.html
This means that jenny will always ignore my own edits unless I also manually edit its internal “json database”. Annoying.
That change was requested by a user who had the habit of deleting twts or moving them to another mailbox or something. I think that person is long gone and I might revert that change. 🤔
