Thanks for the nudge - I've added links to other posts in the series in each one (there are only 3 - you found them all!)

You're welcome :) The harnesses are documented here: https://github.com/eliben/watgo/tree/main/tests Note that I had to switch the harness from wazero to Node (unfortunately!) when…

watgo ( https://github.com/eliben/watgo ) -- a WebAssembly toolkit for Go. Think something like wasm-tools or wabt, just in pure (0 dependency) Go.

According to the official tracker ( https://www.energy.ca.gov/data-reports/clean-energy-serving-... and elsewhere) there were 279 days in 2025 where California was on 100% renewabl…

California is a great example; highest electricity prices in the US (not counting Hawaii, which makes sense) despite significant hydro and fantastic solar capacity. In the last few…

Thank you for the feedback. The idea was to first define what we want the basis functions to be (a pretty abstract definition) and then develop how to actually get that from _norma…

Fixed, thank you! (it's actually r(x)=p(x)-q(x)) (proof-reading through HN is a mildly embarrassing process, sorry about that! I do go over these posts and proof-read them several …

Thanks for noticing, I'll fix it shortly

Right, standalone binaries for CLI tools is great. And if one has Go installed, they can just `go run ...` any tool from its GitHub path, all installation/build/caching happens aut…

Very interesting! I encountered the problems these tools are trying to tackle just recently while trying to guide an agent into creating an in-browser tool for me. Closing the loop…

The underlying issue here is that the Nobel Peace Prize is a useless, politicized joke. It appears to be almost designed to give newspapers something to write about. It's a shame i…

Nice, I'm proud I managed to nerd-snipe you :-) Thanks for taking the time. Seriously, though, I think this solves a nicely framed simpler problem. I was thinking about a more gene…

Great work, Simon -- thanks for sharing! One tool I'd really like to see in this format is a simple "turn the background of this PNG to transparent". Models still refuse to follow …

I also enjoyed working with BF for toy compiler projects; here's a series of JIT compilers for BF in increasing level of sophistication: https://eli.thegreenplace.net/2017/adventur…

Thanks for spotting this, what a silly typo :) ... Fixed

Thanks for the kind words! Regarding ring size, yes I'd say 2^64 is good. Since the representation is sparse, it seems safe but I'd be interested in hearing other views.

Thanks for posting this! Just a quick note that this post is the first in a series: see https://eli.thegreenplace.net/tag/multiple-dispatch for the full series

The Y combinator in Python: https://eli.thegreenplace.net/2016/some-notes-on-the-y-combi... (scroll down, after the concept is explained using Clojure) A bit crazier, in Go with ge…

A quick plug for https://www.goatcounter.com/ - a super lightweight visitor counter. Very much privacy oriented ( https://www.goatcounter.com/help/gdpr ). I've set it up on my blog…

Yes, Factor is mentioned in the first paragraph of the post!

Thanks for the feedback! What do you feel is not finished?

Thanks for the note. Much of the blog post is dealing with this - how the approach I took for the Go implementation is not sufficient for the hacker level - because the code isn't …

Indeed, generating functions are mentioned in a footnote :) Very interesting topic
