To Come Home To Yourself 

May all that is unforgiven in you
Be released.

May your fears yield
Their deepest tranquilities.

May all that is unlived in you
Blossom into a future
Graced with love.

To Come Home To Yourself May all that is unforgiven in you Be released. May your fears yield Their deepest tranquilities. May all that is unlived in you Blossom into a future Graced with love.

Friend gave me a John O’Donohue book recently. It’s quite good.

In the foreground is Saturn's giant moon Titan, its hazy, peach-coloured atmosphere extending into space. Behind is Saturn itself, its upper hemisphere crossed by the shadows of its vast ring system.

Improving Geographical Resilience For Distributed Open Source Teams with FREON In a recent blog post, I laid out the argument that, if you have securely implemented end-to-end encryption in your software, then the jurisdiction where your ciphertext is stored is almost irrelevant. Where jurisdiction does come into play, unfortunately, is where your software is developed and whether or not the local government will employ rubber-hose cryptanalysis to backdoor your software.

Figure from a paper with three cubes:

a) A cube with a rectangular cube connected labels "mouth" and "anus"
b) A cube with double the edge length The tube inside spirals around.
c) Another cube with all linear dimensions doubled, including straight tube.

Caption:
Fig. 1. (a) Idealized model of an animal. (b) Model from (a) increased in size while keeping the gut surface : gut
volume ratio constant. (c) Model from (a) increased in size with identical effects on the surface : volume ratio
for the whole body and for the gut.

This is the idealized model of an animal. You may not like it, but this is what peak performance looks like.

A document announcing the "Fourth ITU-T X.509 Day (2025) event" on September 5, 2025, from 13:00 to 16:00 (Geneva time). It details ITU-T X.509 as a foundational standard for public key infrastructure and digital certificates, outlining its history and applications. The event's objectives include reviewing X.509 progress, assessing post-quantum cryptography readiness, exploring decentralized PKI, discussing cross-border digital identity, strengthening AI trust, showcasing real-world adoption, and identifying future directions.

My favorite thing about social media is the weird people who emerge when you’re talking about basic privacy, and accuse you of having things to hide.

Hey crazy person: *of course* I have things to hide. We all do. Being human means being embarrassed about personal stuff.

This is also why "accept Zcash / crypto as an alternative" is necessary but not sufficient: as long as credit card companies are a major channel for a site's revenue, they are a major source of coercion.

"If you sell NSFW content via any payment rail, you can't use ours" is the barrier to overcome.

If you're a seller who wants to accept Zcash to both improve your customers' privacy and provide resilience against coercion by credit card companies, I will happily answer any questions you have.

And, for fuck's sake, take a first aid/CPR class. You will never, ever regret doing that. These are basic skills that will serve you always and makes that first aid kid more valuable. There's a lot of stuff in there and most people can't do much more than apply band aids.

As I go through this book I’m trying to keep a list of recommendations for cryptographic engineers. It’s short so far, but I expect it’ll get longer as this goes on. Open to suggestions!
