Lots of studies support stretch-mediated hypertrophy: muscles grow more when put under tension while lengthened.

If you do just foo, the following justfile will write a single byte 0x0A to a file named bar: x := "\n" foo: printf '{{x}}' > bar Let's find out where that 0x0A byte comes from. just is written in Rust, and the just parser has a function called cook_s…

There have been words on Twitter, so I thought it would be useful to write down how ordinals came to be.

Bitcoin has inscriptions and will soon have runes, protocols for bitcoin-native digital artifacts and tokens.

If you ask me my views, they will be nearly indistinguishable from those of, for lack of a better term, ideological Bitcoin maximalists.

When a dev tells you that something is weird and hard and they have to change behavior that users rely on, the correct response is somewhere between "Cool story, bro." and "Wah, wah, wah, are the bits being mean to you?".

I'm not sure creating a new fungible token protocol for Bitcoin is a good idea.

Inscription numbers are numbers assigned to inscriptions in the order in which they are created, starting at zero for the genesis inscription.

Ideas for a new Bitcoin testnet: Cool, cyberpunk branding and design, so people pay attention to it and want to use it.

I've been thinking about competitive governance, trying to dissect what, exactly, its desirable properties might be, and how to achive them.

Raph and I have been working hard on ord, the ordinal block explorer and wallet, and have just finished the initial version of the ord wallet send ORDINAL ADDRESS command, which makes a transaction sending ORDINAL to ADDRESS.

I've been working on a numbering scheme for satoshis that allows tracking and transferring individual sats.

Crypto History Prehistory Lots of interesting stuff here that nobody talks about Digital Monetary Trust: Private, anonymous, digital bank eGold Liberty Trust 2009 - Bitcoin Bitcoin launches and is the only cryptocurrency for a while 2011 - Early Altcoins…

A large reputable member threshold multisig operating as functionaries for a Bitcoin-pegged deterministic replicated state machine sidechain with as-compatible-as-possible-with-mainchain semantics is probably more reliable and secure that most alternative…

There are a lot of things that I wish would happen, but don't have the time to actually do myself.

Expanding on this tweet: You could launch a super fancy social networking site with all the features that everyone expects, but built entirely on existing open standards: Sign-up: Pick a domain.

Conventional software configuration is backwards.

Got some minor cuts and scrapes while doing water sports (not the fetish kind you perv), was curious about the optimal way to dress them, which lead to reading at least a dozen papers and articles on wound care and dressing selection.

Federated blind mints have attractive privacy, scaling, and security properties that are highly complementary to those of Bitcoin and the Lightning Network.

Bitcoin will greatly reduce the power of the state, which rests entirely on its capacity for violence.

I don't do as much deep thinking as I used to.

For some reason I'm fascinated by the debris in this vacuum product photo.

The complex priority system that the state is using in many countries to roll out the covid vaccine is reminiscent of this plane boarding algorithm: Yes, it is optimal.

I was trying to find an image reference for what different clipper guard lengths look like.

As an unrepentant degenerate and fan of microeconomics, it should come as no surprise that I find the online sexual economy endlessly fascinating.

The PS5 was released about a week ago, and, predictably, it is impossible to get one.

I wrote a nontrivial AppleScript to merge duplicates in my iTunes library.

One of the things that I personally struggled with when learning Rust was how to organize large programs with multiple modules.

I feel like BGP would be a great place to experiment with PKI systems, possibly with some additional global consensus mechanism.
