Fun stuff...nearly at a million total.view on my little channel. Still weird me out that almost everything comes from a video from a million years ago before I knew what I was doing lol

Have you ever thought about how your computer adds and subtracts? It takes a lot of hardware to handle floating-point numbers like 12.34. I opened up Intel's 8087 math coprocessor chip from 1980 to see how it works...

Fourth run through of my undersea talk...and I keep editing the underlying project so everything is out of date lol... I have a few days yet ...

Hi, I’m a sighted alt text user! Here are some reasons I use it: - Slow Internet on an airplane - I’m over 40, I have no idea who that celebrity is - Bluesky broke images again - My vision sucks and that text is too small to read otherwise - Conveys further context and authorial intent

Experience the Septopert. Not just the new smallest Nopert at 7 vertices, but the smallest possible! We now know every solid with 6 or fewer vertices is Rupert. Noperts Drop: github.com/tom7/noperts The triforce and eponymous 7 are not a cheeky Easter egg—simply a beautiful property of math!

Want proof of the human soul? Easy. Listen to AI music. Also don't... don't listen to that. But the next time you're in a cab you'll probably hear some. (why is it always taxi drivers... anyway)

the AI industry is full of people who would automate away playing with a kitten

Had fun this weekend (with heavy Claude assistance) porting my childhood favourite Spectrum game to the Beeb: Chuckie Egg 2 bbc.xania.org?autoboot&dis... Lots of fun reliving my childhood and play testing. Yet to try it on a real Beeb (treat for this evening!)

Every time I see a cybertruck on the road I yell at them to get more polygons. It's not 1991 anymore

Working hard on slides for my upcoming talk at C++ Under the Sea. At the "oh my golly how is this going to fit in an hour" stage, and about halfway through fleshing out the deck...

My CppCon Keynote, “The Address is Not The Place” is now up on YouTube! It’s not often that we get new tiers added to the memory hierarchy of computing, but it sure is fun! You can certainly get ahead of the curve by thinking about the programmatic challenges (and possibilities) this will cause.

Had fun speaking with @bloopmuseum today at CppCon; if you’re here, swing by their booth while they’re around!

 I haven’t been yet, but they’ve apparently bought out a huge abandoned government building in Pittsburgh and are filling it with a ton of vintage computing equipment.

The Bloop Museum is awesome! Drove 8 hours to visit it with my son a few months back! Great to hear it's getting some celebrity endorsements :-)

turns out compiler explorer isn't just a website

c++ pals! What retro gaming stuff would you like to see at CppCon later this week?

I finished my port of legendary game Paradroid from the C64 to the BBC Micro! Check it out here to download the disk, play in the emulator or read through the code: bitshifters.github.io/posts/prods/... [Disclaimer: AI assisted with Claude Code.] #retro #retrogaming #bbcmicro #c64 #demoscene

Work wanted to film me talking about things that I care about ... so obviously I talked about reading assembly and why it still matters :) www.youtube.com/shorts/cZbkQ...

Arg. What happened to Google home stuff? I used to come home and "hey Google, play some music please". Today I said that three times: - sure here's a playlist called sunflower - sure here's some (giant long playlist name I didn't recognise) - sure here's a playlist called "some music" Srsly...

Can someone help my pal make it up to Chicago for #vcfmw ? Thanks in advance!

Wondering vaguely if I'm now more an "executive programmer" these days.

In which I fart about to recreate a silly thing I did at Google, 16 years ago... xania.org/202608/recre...

What time is it? Computerphile time! Sean does another great job of editing my word salad of excitement as I go into how your computer tells the time!

I finally got `import std` to work on @compiler-explorer.com godbolt.org/z/3P5b11f5M #cpp

Book now for an upcoming C++ workshop! Sep 12-13 (Aurora, CO): cppcon.org/class-2026-b... Sep 21-22 (Kongsberg, NO): ndctechtown.com/tickets Oct 14 (Breda, NL): cppunderthesea.nl#workshops

Ok...I am now cautiously optimistic about what cool tricks I can play with C++26 (obviously for my emulator....)

Poking about with compile time consteval programming. Finally understanding why @hanicka.net wants everything to be constexpr. Also, trying to bridge the gap from compile time data to static constants at runtime is painful...

[back in the day] Low level programmers: "It's all about optimizing every byte and every cycle, use as little RAM as you can" Other devs: "Nonsense. We have plenty of RAM" [today] Low level programmers: "Well well well"

Some hobby JavaScript work (admittedly with lots of LLM help) has led to some jsbeeb updates too: hqx support, disc structure visualiser, HFE disc image archive support too. Nice to knock out some very old todos (mostly while I was gardening!)

It's Bandcamp Friday and I released my first original EDM track! #music #electronicmusic #indiemusic nocturnalplant.bandcamp.com/track/photos...

Are you in the US and trying to order a Pretty Eight Machine vinyl from inversephase.bandcamp.com/album/pretty... for #BandcampFriday? Only folks in Europe or the UK can order them right now from @bandcamp.com - US folks, order at www.savepoint.store/product/pret... or visit @bloopmuseum.bsky.social

Excited to be giving a keynote at CppCon 2026 this September, go check it out!
