Had a great time, sadly couldn't stay longer. Caught @adriansdigitalbasement.com and other luminaries at a panel; fantastic stuff. Sadly still didn't manage to get a selfie with Adrian: next time!!

A panel of retro YouTubers; Adrian Black and Veronica Explains among them (and many other who I've now subscribed to!)

Apparently my YouTube channel is 11 today! The stats tell me my most watched video is one I did very early on about how Wolfenstein 3D (the DOS era game) worked. I've been threatening to make a Doom and Quake followup ever since...oops. www.youtube.com/channel/UCC3...

Notification: "Congrats your channel is 11 today!" from YouTube

Top 5 screenshot:
1 Wolfenstein 3D -> 290k views

Ok a better one? This time I output to tmpfs and then encoded from that.

Matt Godbolt @matt.godbolt.org · 11/07/2026

I seem to have a big where I keep losing sync but this could be the video encoding backpresuring the capture which obviously has to keep up...

Some people talk about "put it in godbolt and see what happens". In this photo the Cray's RAM usage was measured by putting Godbolt in *it* :)

C++: The Documentary premiered last week, and will be live to the world at 7pm UTC tomorrow: www.youtube.com/watch?v=lI7t... Had a blast moderating the panel and getting to know some absolute C++ Legends! Thank again to @cultrepo.bsky.social and my employer Hudson River Trading!

Managed to distract myself completely yesterday instead of edit the next Two's Complement.

Had fun yesterday at the GCASR 2026 conference! It was a delight to be able to walk to it from my house, and I met some very interesting folks and learned a ton. My own awkward presentation was out of place but at least got some laughs! Thanks for having me!

Back from C++Now and wow, what a conference. I'd forgotten how beautiful the venue is, how intimate the setting, how friendly everyone is and how much you really get to know all the other attendees. Loved it!

Me at the lectern in front of my slides reading "Interlude: GCC inline asm syntax"

Panoramic photo of the campus; the area between the venue and the hotel. Beautiful sunny day, mountains and heather

Selfie of me in the snow! Thick snow everywhere: it snowed one day but was beautifully sunny every other day.

Sharing this random doodle from a meeting 6 years ago as part of #badhumanart inspired by @lefticus.bsky.social :) Clearly it was a riveting meeting (can't remember what it was about but I've kept this doodle ever since)

I really appreciate the 6mo free, @anthropic.com ! Yay but - I'm already on 20x and I can't accept it... - please help :)

Screenshot telling me I can get 6 months of Max! Yay!

Screenshot of what happens after I accept the Max 20x. I am already on 20x so can't "accept" this, only "downgrade to 5x more usage" :(

I just rediscovered a mind map of the CppCon presentation I gave earlier this year. A window into my process!

Handwritten mind map on plain paper with interconnected bubbles and boxes exploring C++ ecosystem topics. Clearly readable elements include:
Top area: "Build community", "IKEA doc", "Committee", "Know how stuff really works"
Left side: "Circle", "Ranges", "Reflection"
Central node: "C++" connecting to "Compile", "STL", "Stepanov"
Right side: "Welsh", "School", "Local meetup", "conferences"
"Eco system" (boxed) connects to:
Build tools: "make", "OSS"
Compiler infrastructure: "libclang", "Sanitizers", "clang", "LLVM"
"CE" (Compiler Explorer)
"libraries", "boost", "FMT"
"tooling"
"AI?"
Throughout the map are numerous connecting arrows and lines showing relationships between concepts. Several bubbles contain handwriting that's too unclear to confidently transcribe, along with various time notations and red/pink annotations.

Similar here in the outer edges of "war-torn" Chicago. Kids playing outside, folks walking their dogs in the uncommonly warm October afternoon. Some people have the audacity to water their lawns; unaware of the peril they're in!

Suffering in a war zone...not. me sat outside my house with my dog in beautiful sunshine and peace and quiet

Well, poo. Post conference cold is common; after all the stress of preparing and presenting, being surrounded by humans in a confined space etc it's not too surprising that after the come down, one gets a sniffle. Unfortunately mine came with a side order of losing my sense of smell :/
