Whew. Here's the final post in the series about my attempts to connect an approach to computing scattering amplitudes in quantum field theory to the world of machine learning. The TL;DR is that YES positroid-based networks work and can even be applied to transformers, but simply aren't as useful as your standard ReLU networks. #Mathematics

We strongly oppose the Unified Attestation initiative and call for app developers supporting privacy, security and freedom on mobile to avoid it. Companies selling phones should not be deciding which operating systems people are allowed to use for apps.

Unified Attestation

Unified Attestation is a free, open-source alternative to Google Play Integrity with offline verification and simple app + server integration.

Neat little set of experiments I did :)

I'm really feeling seriously depressed about the disaster in orbit today, I already had a couple of meetings and a flurry of emails about the fucking awful SpaceX million satellite filing.

It's Waitangi Day here, and I'm looking forward to learning a lot about Māori culture and seeing some geysers today. I'm going to try to lean in to the stunning natural beauty of the land I'm on today and the Indigenous knowledge that goes with it.

Seriously considering getting the fuck out of this country. Every day feels more and more dangerous to stay here. I only wish others without the financial means to do so had a chance to flee as well. We have never been more the opposite of what we claimed to be.

With everything going on in #Illinois right now with #ICE , I just want to post this plaque from the town square of Aachen, Germany:

It's becoming increasingly clear to me that Reflect Orbital's fucking stupid giant mirror satellite, with absolutely NOTHING useful to offer, which will cause countless safety issues, ecological disasters, and destroy the night sky, is going to launch.

A bunch of astronomers and I have sent out a fact sheet about them to a bunch of journalists, but very few are going to write about this. So, let me try posting it all here.

Here's what I know about Reflect Orbital and all the downsides:

A few weeks ago I got the chance to totally nerd out with folks about building #quantum computers out of real, individual atoms. Within just an HOUR, they learned the basics of quantum mechanics, neutral-atom quantum computers, and how to use them to solve the maximum independent set problem - they CRUSHED it! Running this workshop was really a life dream of mine and it was so great to see their eyes light up. No corporate talk about quantum supremacy - just pure excitement over something cool!
