Minimum Viable Block Chain
Block chain is agnostic of any 'currency' and it can (and will) be adapted to power many other use cases. This is a ground up explanation of why the particular pieces (digital signatures, proof-of-work, transaction blocks) are needed, and how they all come together to form the minimum viable block chain with all of…

Why software engineers like woodworking
The smell of fresh pine sawdust filled the air, with more floating up as I sanded the last rough corner of the stool. My toddler was happily sanding her own block off to the side.

Why I don't miss React: a story about using the platform
Just over two years ago I left a role at a London based startup where I lead development of a large, React based e-commerce frontend to join Google to work on Chrome DevTools. My initial focus was to introduce Web Components as the new fundamental building block of all new DevTools features and UI. With the recently…

Svelte is the most beautiful web framework I've seen
I first heard about Svelte a year ago, when Rich Harris presented it at JSConf EU 2018. The demo gods were a bit harsh on him, but it didn't matter to me, because I was so impressed by his philosophy and ideas that I was already sold. I knew he'd work out the kinks, go through a few major versions, and Svelte would be…

I wrote a Game Boy Advance game in Zig
The Game Boy Advance is an interesting game console. It has a modern-style CPU (32-bit ARM, lots of registers), but uses an old-fashioned tile based renderer like how the NES did it in the 80s. Don’t get me wrong, since its one of Nintendo’s last tile-based systems, they took the idea as far as it can go with fancy…

How Does GPT-4o Encode Images?
Here’s a fact: GPT-4o charges 170 tokens to process each 512x512 tile used in high-res mode. At ~0.75 tokens/word, this suggests a picture is worth about 227 words—only a factor of four off from the traditional saying. (There’s also an 85 tokens charge for a low-res ‘master thumbnail’ of each picture and higher…

XCurl
It is often said that Imitation is the Sincerest Form of Flattery. Also, remember libcrurl? That was the name of the thing Google once planned to do: reimplement the libcurl API on top of their Chrome networking library. Flattery or not, it never went anywhere. The other day I received an email asking me about ……

In 2018 I wrote another post about my then newest build. We’re now in the year 2020. And finally, the quest to get a machine to … Continue reading The Octo-Bouncer

A comparison of Rust’s borrow checker to the one in C#
OK, so C# doesn’t share the Rust concept of “borrowing,” so it wouldn’t technically be correct to call this “borrow checking,” but in practice when people talk about “Rust’s borrow checker” they’re talking about all of the static analysis Rust does to ensure memory safety, for which I think this qualifies.
