Scaling Postgres to the next level at OpenAI
TIL OpenAI uses (used?) one primary write instance for their PostgreSQL cluster with dozens of read replicas. This powers the core ChatGPT service which has hundreds of millions of users and, needless to say, is a critical backbone to it.

The talk implies they shard now, but the whole video emphasises all the optimizations they did in order to support their workload through a single primary. It isn’t mentioned at what time they switched to sharding, but it’s heavily implied that … ⌘ Read more

I noticed Google put out this article: https://android-developers.googleblog.com/2025/09/lets-talk-security-answering-your-top.html it’s very current day Google, but the comments under the YouTube video are pretty on point and I saw a few familiar faces there. There is also, unexpectedly, ways to contact Google.

First a form for “teachers, students, and hobbyists”, that I filled politely, as someone who falls under their hobbyist category. It can be filled both anonymously, or with an e-mail attached, to be contacted by them (I chose the second option).

Also a general feedback and questions form, that I was not as polite in and used to send them the following message:

I have already provided some feedback, in the teacher, student and hobbyists form/questionaire, as well as an open letter I’ve recently sent to the European Commission digital markets act team, as I do believe your proposal might not even be legal, given the fact it puts privacy-focused alternative app stores at risk (https://f-droid.org/cs/2025/09/29/google-developer-registration-decree.html) and it was proposed this early, after Google lost in court to Epic Games, over similar monopoly concerns. Why should we trust Google to be the only authority for all developer signatures, right after the European courts labeled it a gatekeeper?

Assuming this gets passed, despite justified developer backlash and at best questionable legality, can you give us any guarantees, this will not be used to target legal malware-free mods, or user privacy enhancing patchers, like the ones used for applying the ReVanced patches? I have made a few mods myself, but I am in no way associated with the ReVanced team. I just share many peoples concerns, Google Chrome has been conveniently stripped of its manifest v2 support, that made many privacy protecting extensions possible and now you’re conveniently asking for the government IDs, of all the developers, who maintain these kinds of privacy protections (be it patches, or alternative open-source apps) on Android.
