I spent an inordinate amount of time this year subtweeting articles, commenting on policy and discussing corona with folks on Twitter. Because I read studies and listened to weeks worth of podcast content on the topic in three languages (e.g. Das Coronavirus Update and This Week in Virology) I’d like to believe I have at… Continue reading How to deal with Corona
Mask math for fun
I wanted to get an order of magnitude sense of the utility of non-medical masks. Specifically their usefulness against floating droplets at a reasonable distance, and not from someone coughing loudly; those people can easily be avoided. In addition I focus on short term exposure. In other words, should I worry when waiting in an… Continue reading Mask math for fun
North Korea’s “Cryptocurrency-1”
North Korea’s “Cryptocurrency-1” Cryptocurrency developer Virgil F. was arrested a few days ago at Los Angeles International Airport. Arresting travelers at the airport right before they leave appears to be a thing for the FBI, e.g. a OneCoin founder was arrested at the same airport on his way out, and Malware Tech was arrested at… Continue reading North Korea’s “Cryptocurrency-1”
Cargo Cult veldexperiment
Cargo Cult veldexperiment NRC schreef onlangs in hun redactioneel commentaar: Interessanter is de benadering die de Nederlandse denktank Sustainable Finance Lab (SFL) deze maand suggereerde. Nederland is volgens het SFL bij uitstek een geschikt land om te experimenteren met een door de centrale bank gecontroleerde digitale munt, omdat het gebruik van cash in ons land… Continue reading Cargo Cult veldexperiment

Van wie is deze bitcoin? — Deel II

A Crime on Testnet
On a warm summer day I crave a frappuccino. Unfortunately drugs such as caffeine, sugar and cacao were declared illegal decades ago. This happened because young unemployed college graduates often felt triggered by loud caffeinated rich people. Sugar was causing mass obesity and was also a carcinogen. Cacao was too clearly associated with oppression. These… Continue reading A Crime on Testnet
Van wie is deze bitcoin?
Van wie is deze bitcoin? This post is in Dutch. The short English version is in this Twitter thread: You may want to turn off transaction email notifications, and ask your favorite wallet provider to use PGP. In general email notications are a big privacy / security risk; they form a detailed record of stuff that's… Continue reading Van wie is deze bitcoin?
Bitcoin on an Orange Pi (using Armbian)
Bitcoin on an Orange Pi (using Armbian) There are some good articles on how to run a Bitcoin Core full node on a Raspberry Pi. But there are other pies, some of which have better performance. That’s great news, because the Bitcoin blockchain has grown a lot recently, so any extra CPUs, RAM and storage are… Continue reading Bitcoin on an Orange Pi (using Armbian)
Matreon: Bitcoin Core + Lightning + Rails on AWS
Bitcoin Core + Lightning + Rails on AWS Recently I’ve been working on a project code-named Matreon. It’s like Patreon, but for the matriarchy. In a world of increasing online censorship, being able to host your own website and process your own payments really helps. Step 1: your fans pick a monthly amount to contribute Step… Continue reading Matreon: Bitcoin Core + Lightning + Rails on AWS
