Fun fact: OpenAI handles 800 million users on ChatGPT with just one PostgreSQL primary and 50 read replicas 🤯 Today, OpenAI published an engineering blog explaining how they scaled their Postgres setup to support a massive 800 million users using a single primary and 50

Two macOS apps I wish I'd known about earlier: https://t.co/mOdaSYCFdu and https://t.co/rtmJdxUG1g. Together they make navigating the computer via keyboard so much easier and faster. Very good. Both are free.

Did you know that the backend of #MetaThreads is built with #Python 3.10? It's running on Instagram's #Cinder fork that includes a JIT, lazy-loaded modules, pre-compiled static modules, and a bunch of other interesting tweaks against vanilla Python 3.10. https://t.co/RiiGfQSLMJ

This is from October but I still find it fascinating. GPT-3 can be told that it's bad at math and should therefore use Python for anything beyond simple arithmetic! Current LLMs are like an infant AGI -- we've just started learning how to teach them to think and problem solve

Why Apple’s announcements today are a big deal, a thread. 1/

Any sufficiently large organization is at the mercy of Conway's Law.

The stuff happening on the Stable Diffusion subreddit right now is pretty wild - since the model can be run by anyone on their own machine if they have a decent GPU

They're also both running the latest version of macOS.

I have two separate MBPs that routinely crash. They're stock with no peripherals attached. Time to go back to Linux?

I've not seen this trick before: when you download the youtube-dl binary you're getting a file that looks like this: #!/usr/bin/env python PK^C^D^T^@^@^@^H^@!(<... That's a shebang line followed by a zip archive containing Python code!

The problem with this whole situation is that in a vacuum of information, people speculate. Facebook needs to make a clear statement on the data that’s in broad circulation; when it happened, where it came from and what’s in it. Without that, confusion and speculation reign

After SolarWinds, is everyone auditing their CI/CD pipeline code? Here is a good example of a pipeline vuln. Attack on VS Code's CI/CD pipeline through command injection in a script. PoC gets a reverse shell.

The violence at the Capitol today was an attempted coup and act of insurrection egged on by a corrupt President to overthrow our democracy.

All of this was predictable. It was predicted. And the lasting shame of history will be on all those who refused to act out of cowardice, ambition, or their own allegiance to an authoritarian movement.

It’s crazy how few people understand basic startup equity but are faced with major career decisions based on these concepts.

Why has the United States handled this pandemic so badly? The Editors note that although we came into this crisis with enormous advantages, our current political leaders have demonstrated that they are dangerously incompetent.

I published a blog thing on effective political giving! Tl;dr is to give directly to candidates, enlist others to join you, not overthink it, do it as soon as possible, and as far down the ballot as possible. https://t.co/yWq75Q4eE9

Thinking of everyone out west where wildfires burn in many states. This is what the sky looked like this morning in San Francisco. The climate crisis is real.

Some take-aways from https://t.co/OpbA1Bhuaz by @mipsytipsy: * Fully automate deploys (and rollbacks) - corollary: database migrations should be additive * Engineer who made the change(s) should own build and deploy * Observability tools needs to monitor deploys ensuring it works

#Python tip: Adding __slots__ to a class is the easiest optimization you will ever do. * Faster instantiation: c=C() * Faster attribute reads and writes: c.x=1 * Smaller object size * Makes compiled language people happy (Java and C++ classes declare attributes up front)
