Ep 518 - Online C++ Tools You Must See! (2026)

Pedantic me would like to point out that I've eaten at least 4 different varieties of avocados in the US alone.
And if you buy avocados in Florida they are likely *not* haas.
The physicists I know do things like intelligently order the operations on the floating point to group small things with small things, and everything stays floating point at the precision they care about.
Certainly works for real world simulations, but I'm curious about even higher accuracy
Does anyone know of a computation problem domain where precision and accuracy are most important, over any performance concerns?

Have a link?
One of the compilers is wrong in this case. But at the moment I forget which one. I did look out to tho
23.01.2026 17:54 — 👍 1 🔁 0 💬 1 📌 0One of C++'s main strengths is type safety, when used correctly.
This is a lesson that every language has learned, from Python type hinting to TypeScript
By comparison C doesn't even have a type system.
All is the weakness in C++'s type system is inherited from C

I need a documentary about people who won trips on game shows in the 80's and 90's and how those trips went

Ep 516 - C++26's User Generated static_assert Messages

If you have patience it seems to work out, eventually.
Particularly useful for things you cannot donate (like an old TV that still works) put it up for free and it's probably gone by the end of the day.

A shocking number of people in local online marketplaces have the hobby of messaging you to ask "is this still available?" Then literally never responding again

Fun fact, this "world's most complicated/important machine" that Veritasium just covered runs C++!

I know because I have had students from ASML on multiple occasions (they had me out there for training and to speak at a meetup back in 2018!)

Dear Jason, I hope you remember me. A few weeks ago, you were trying to sell your 2 Garmin watches on Craigslist. You decided to just give me the watches because they were not working properly. I was able to get one of them to work, so I am sending you a check for $50. I thought about paying your generosity forward, but paying it back works too. Thank you again for your kind gesture and please put this $50 to good use. Merry XMAS + Happy New Year!
I tried to sell my last generation @Garmin.com watches, but then realized they weren't keeping charges very well.
The guy I gave them to for free sent me this lovely note and $50.
I'm forwarding the $ to ALS research in honor of Rainer Grimm, consider contributing to ALS research if you can.

FYI, besides having the evolution of C++11->C++26 and an adventure game, my website now also has a fully cross-linked database of C++ Weekly episodes!

Want to see which episodes correlate to which parts of the standard and then jump into the adventure game engine to explore?
Ep 511 - move(obj).fun() vs move(obj.fun())

Nice. 100% recommend.
BTW apparently I went too far east. 🪢
I've built a text adventure game engine on top of the C++ Standard. Why? I have no idea. But it's a learning tool with quests and time travel and artifacts and NPC's and XP and ... well, you just have to check it out!
