Torsors (2010)
When you first read about "torsors", they're bound to seem a bit too darn sophisticated for their own good. Mostly this is because nobody explains them very well. So, I want to convince you that they're actually very simple and natural. I'll do this by giving you three examples from physics:

I should have loved biology
In biology class, biology wasn't presented as a quest for the secrets of life. The textbooks wrung out the questing.

The Scaling Hypothesis (2021)
On GPT-3: meta-learning, scaling, implications, and deep theory. The scaling hypothesis: neural nets absorb data & compute, generalizing and becoming more Bayesian as problems get harder, manifesting new abilities even at trivial-by-global-standards-scale. The deep learning revolution has begun as foretold.

After self-hosting my email for twenty-three years I have thrown in the towel
Many companies have been trying to disrupt email by making it proprietary. So far, they have failed. Email keeps being an open protocol. Hurray? No hurray. Email is not distributed anymore. You just cannot create another first-class node of this ne

Why is Rosetta 2 fast?
Rosetta 2 is remarkably fast when compared to other x86-on-ARM emulators. I’ve spent a little time looking at how it works, out of idle curiosity, and found it to be quite unusual, so I figur…

C isn't a programming language anymore
Phantomderp and I have both recently been very aligned on a particular subject: being extremely angry about C ABIs and trying to fix them . Where we’re not aligned is why we’re mad about them.

The most backdoor-looking bug I’ve ever seen (2021)
This is the story of a bug that was discovered and fixed in Telegram’s self-rolled cryptographic protocol about seven years ago. The bug didn’t get any press, and no one seems to know about it, probably because it was only published in Russian.

Please Use ZFS with ECC Memory (2014)
In this blogpost I argue why it's strongly recommended to use ZFS with ECC memory when building a NAS. I would argue that if you do not use ECC memory, it's reasonable to also forgo on ZFS altogether and use any (legacy) file system that suits your needs.

Futurist prediction methods and accuracy
I've been reading a lot of predictions from people who are looking to understand what problems humanity will face 10-50 years out (and sometimes longer) in order to work in areas that will be instrumental for the future and wondering how accurate these predictions of the future are.
