valgrind is another one I wish had a real windows equivalent

There is no cow level!

Bluesky Map Interactive map of 3.4 million Bluesky users, visualised by their follower pattern.

I made a map of 3.4 million Bluesky users - see if you can find yourself!

bluesky-map.theo.io

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

As someone who listened to it, I liked it but agree the physical book is the way to go!

Oh, you like cloning? That makes two of us

If you're into sci-fi short stories I definitely recommend it - planning to follow it up with a re-read of Exhalation (his more recent collection of stories).

Just finished a re-read of "Story of Your Life and Others". One of my favorite short story collections ever, last read it probably about a decade ago and despite that, some parts of the stories stuck with me. It was cool to get to read them again given how I've changed and what I'd forgotten.

first htmx dies, now opencode - when will it end?

Summary of github stats for 2025

If you asked me to guess what my most productive day was in 2025 (in terms of commits) I would never have guessed Monday! 🤯

My year in:
- Books: www.goodreads.com/user/year_in...
- Code: git-wrapped.com/profiles/Hea... (source of this image)
- Everything else: heathhenley.dev/posts/2025-s...

📎 it looks like you're challenging the status quo. have you considered that this will make the status quo very sad? look it's crying now

maybe @wagslane.bsky.social 🤷‍♂️?

don’t know if he’s active on here though

Thanks for making these Matt they are great, looked forward to catching them each day

there's vomit stderr already, claude's spaghetti
he's nervous, but assures it's production ready

Climbing shoes and chalk bag

Here we go! Took a long break again, been mostly donating to the climbing gym every month - but definitely missed it.

Day 21: Summing integers? Compiler vectorises beautifully—8 at a time! Switch to floats? It refuses, doing each add individually. Same code, totally different output. Why? 🤔

Simple query refactor - 100x faster A simple refactor of a postgres pagination query improved performance significantly, this is an explanation of that update. The basic is that if you have a query like a < c or (a = c and b < d) - try...

Here are some details: heathhenley.dev/posts/pg-tup...

I recently speed up a cursor pagination query in postgres by 100x by switching the where clause from something like:

where (a < c or (a = c and b < d))

to

where (a, b) < (c, d)

Maybe you db people are aware of this but something to keep in mind / check for when profiling and optimizing!

Excuse me GitHub, your Microsoft is showing (charging for time on self hosted runners 🤯)

Active shooter reported at Brown University in Rhode Island An alert sent by Brown University told students to lock doors, silence phones and stay hidden until further notice.

An active shooter was reported near Brown University's campus in Rhode Island, the university said Saturday. The suspect is still at large, officials said.

lol true I should have a said *another* Easter egg

Ok at the risk of sounding like a crazy person...I feel like the input for day 12 of #AdventOfCode looks suspiciously like a hexdump, and the bytes mostly map to printable chars if you take them as hex values - but I wasn't able make anything of it

I think there's an xmas easter egg in there maybe!

11.5 days in Ocaml!

Did the solver one in python but saw some solutions that used Lp in ocaml so might switch. Or maybe try this solution algo - only one that I've seen not setting up / solving the system of eqns

Big thanks to @was.tl for all the work and creative energy you put into these puzzles!

I just completed all 12 days of Advent of Code 2025! #AdventOfCode adventofcode.com

That's a wrap on aoc 2025 🎄 - I like the shorter format and really enjoyed seeing everyone's solutions in different languages.

Until next time...

just read through this www.reddit.com/r/adventofco...

first approach that I saw not relying on setting up and solving the system of equations (either with a solver or not) - I don't fully get it, would have to implement it - but seems cool!

reviewed more solutions - man I made that way too complicated, it was fun though I guess lol

LOL I did this

I just completed "Reactor" - Day 11 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/11

This was another hard one for me but I enjoyed it, as usually solution here - depending on when you click it will be in varied states of tidied up
