Check out my new C++ research tools! Disclaimer: I used AI exclusively for this. I wanted to see how far I could push the tools. 1) LaTeX to markdown: github.com/lefticus/cpp... 2) Diff tool of per-stable-name of the markdown cppevo.dev/diffs/cpp11-... to see how <array> has evolved!

I just posted my little intro to the Advent of Compiler Optimisation #AoCO that I announced yesterday. Check it out (and laugh at my terrible editing) at youtu.be/j-BwR-Cw0Gk?... @!4 if you want to watch the series, subscribe! :)

Cripes; turns out if you advertise you get more subscribers hehe! Can't wait to release the videos and posts in a couple of weeks!

Of course this series will demonstrate ways to use Compiler Explorer - and is part of a fund raiser too. shop.compiler-explorer.com and www.patreon.com/cw/mattgodbolt

This December, I'll be posting an article & video each day until Christmas in the Advent of Compiler Optimisations! #AoCO2025 Each day we'll explore a fun optimisation in C or C++; some low-level, x86 or ARM-specific, some high-level. Hope you'll join me! YT: youtube.com/mattgodbolt Blog: xania.org

Sounds like something @aresluna.org might have some clues about - any ideas?

Kyle Kingsbury is not a journalist. He is not an op-ed writer. He is a computer safety researcher. And he has written one of the most compelling, comprehensive accounts of the ongoing hell in Chicago that you could possibly imagine. In under 1600 words. aphyr.com/posts/397-i-...

Lovely to hang out with the lovely folk at Solid Sands: youtu.be/5hvMDUWjw-Q

I try to muddle through a few encodings to explain how (some) Ethernet works at the wire level. Thanks as ever to @seanski44.bsky.social for making me appear to make sense! Watch here! www.youtube.com/watch?v=SJE2...

I'll be chatting about testing, coding, Compiler Explorer, why I love optimisation, and origin stories (and more!) in a few hours' time with my pals at Solid Sands. Please, join us: register with the link below! meet.zoho.eu/pdtm-xue-gmu

Jason Turner of C++ Weekly spoke with us about the joy of puzzles, the changing directions of an interesting career, and the C++ programming language. We talked about C++; but only a little. 🎧 embedded.fm/episodes/513 #puzzles #author #C++ #learning #embedded #engineering #podcast #cpp #career

New Podcast Episode: @matt.godbolt.org is back after 5 years! And he's sharing stories about breaking through layers. Sometimes your “disk write” is a network hop in a trench coat, and your “fast path” hides a page fault. Godbolt's rule will help. corecursive.com/godbolt-rule...

I have a plea for you. I need an automotive engineer familiar with programming of the safety systems in a crash. This is both an engineering passion of mine, and deeply personal. Hell, I will pay them an hourly rate. Story I've tried for years. It feels like I've hit a wall on millisecond logic.

Ooh! It's me again! www.youtube.com/watch?v=gg4p... - trying to teach an old dog some new tricks (again!) This time at the fantastic C++ on Sea :)

If you see this, quite with a robot that isn't from Star Wars, Star Trek, Doctor Who, or Transformers.

Freezing cold as I've been doing a bunch of filming and I can't have the heating on without making a noise :-)

Finally, a personal request: I've been bedridden for the last year with medical issues, and I'm just now finally getting set up with a surgeon to get them fixed. I'm not able to work in this condition, so if you can spare a few dollars, that'd really help. ko-fi.com/fooneturing

Who knows what mysteries I'll find on this (if I can find a drive)

🚢 New Changelog interview! changelog.fm/663

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

I am so lucky to get to talk about things I love in Computerphile! Old hardware, cool encoding, prog rock and folks also spotted some Easter eggs in the background :) youtu.be/VEyVm6dU55c Very fortunate to get these opportunities; hope I can find time to keep doing after I start my new job!

It's Monday! It's raise up my fellow YouTubers time! #1 @bloggospow.bsky.social bsky.app/profile/blog...

This is the mug that stays near the computer, freeing other mugs to travel about the house.

One of my favourite talks to have seen in person just got published: youtube.com/watch?v=sIZU... go check out Walter's brilliant presentation!

I've been thrilled with the popularity of the mugs; thanks to those who've bought one (or more!) Every sale helps Compiler Explorer!

Are you ready for Halloween or the next Talk Like a Pirate Day?? jason-turner-shop.fourthwall.com/products/con...

Every year, CppCon has a “Back to Basics” Track, which they also upload to youtube. I highly recommend all of them. 

Instead of being constrained to “old school” CS teaching logic, it’s a demonstration of fuller, modern capabilities.

Colleges do a terrible job of teaching C++.

 It’s not “C with Classes”. Injected into curriculums as a demonstration of early CS concepts, it leaves many with a sour taste.

 Students later immediately fall in love with the first language that *doesn’t* feel that way.

It can be hard to delineate me from my projects, and even my projects from one another. I typed this thing up and I think it might do an okay job: www.patreon.com/posts/140227...

Top marks if you spot the @compiler-explorer.com swag in the video :-)

Very sad news about Rainer, who passed away earlier this week. If you can help support #ALS research please consider donating. My thoughts are with his family. We as a C++ community were lucky to have him.

And we're back. A temporary misconfiguration - we have fixed it and all is well..sorry for the problem! -mg

Investigating why Windows compilers are down! Watch this space, and sorry for any inconvenience -mg

lock in friends. look out for each other. we're gonna get through this together.

Coming to your from the warzone that is Portland Oregon. Yesterday, 1:30pm downtown by the Federal Building and Police HQ: total mayhem! Someone was actually picking up some trash in the park! A couple miles away on Hawthorne, someone was driving a late 70s Ford Thunderbird. Oh the humanity!

not to point at anyone in particular, but I have been in and on many different internet communities of various shapes/sizes/technologies and one mistake I consistently see made is assuming the technical part of running a community is the hard part. it's not. it's the social part. it's moderation.

Written 55 years ago, Schulz's heartfelt clarity cuts through the noise, even today. h/t @tisserand.bsky.social

Check out my C++ On Sea 2025 talk - The Power and Pain of Hidden Symbols! This talk is very important for performance and binary size, and double important if you do crossplatform development! youtu.be/-hNv1-FmAec

How exactly do you get code onto a computer? Like, the machine code? Surely you need a program to assemble it...but if you don't have a computer yet, how do you start the whole process!? youtu.be/Pu7LvnxV6N0?... One offhand remark in the middle of this video stole 4 days of work from me :-)

My new @compiler-explorer.com mug joins the family!

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 :/

Huge congratulations to Jason for making 500 high quality C++ videos in a row without missing a single week!

A history of ARM, part 1: Building the first chip | Discussion

This was a thrill to present. Hopefully you'll enjoy it too and there will be a surprise and a laugh or two along the way. It's a bit of a departure from my usual content (you'll see...) and I was very nervous. I hope I still get my points across. Enjoy!
