Static memory allocation is widely used in quite a bit of embedded software, particularly safety critical stuff. There it's often latency related since you don't want hangs while memory is allocated. I've even seen it on some

I had that when workign with a lot of other Europeans. When I moved to a company where everyone was British I had to re-adapt, particularly because I'd become more direct after working with a lot of Germans.

The hydration breaks are a FIFA thing, we can't blame the US for that one. We're not really seeing the ads and half time crap and things as the international broadcasters don't show them.

Traditionally everyone had sash windows ("sliding windows") or casement windows ("swing open") made from wood. Nowadays sash windows are very expensive so almost everyone has casement windows, or even casement windows th

This might sound ridiculous to you but in the U.K. we generally don’t have tilting windows. They are really common in Germany though.

In the UK people predominantly use debit cards but credit cards are widely available. Everyone gets a debit card with any current account (i.e. non-savings account). In March this year there were 2.3 billion debit card transactions vs 400 m

I think most people didn't really care enough because if they knew C++ and they cared enough, they could still effectively contribute to the kernel.

That's not really true at all though, even in very complex software it's pretty rare to have more than ~10 external dependencies in a C++ project. People tend to roll their own a lot more, partly because dependency management is a

It's alright, just get ISO27001 and list them as risks!

Of course but sometimes designers like architects design something that can’t easily be built.

Coding up a decent performing basic 3D finite element solver from scratch in C++. Still needed to know what I was doing but it’s a non trivial problem. I still couldn’t get it to do more advanced stuff.

It’s non trivial now - will it get easier in 12 months though?

I have found this with (mechanical) engineers. They know what they want to see but don’t understand the underlying details which are more mathematical than the average engineer is able to work with. So the people working on engineering soft

Depends on the task and the writing though doesn't it? There's not that much depth in a lot of 'everyday' writing. For many tasks that means that you don't need to be hyperintelligent - reading a recipe or a shoppin

My much larger company has got people already using various models through Bedrock because the Claude and OpenAI limits are too harsh and it's too expensive.

C APIs are much more annoying to wrap in Go than in Rust because of lack of enums (important) and unions (less important).

> Rust still rely on many C and C++ libraries Yes but Rust has a lot more availability of libraries to do stuff as a result. Want to do anything ML or scientific? You at least have a route in Rust where you don’t with Go.

About 12 years ago I went to go and work on some legacy C++ software when I was very green. We had a big code base and it had enum Bool { False = 0, True = 1 } everywhere. I thought it was a good idea to rationalise this since we had conver

Thanks for all your hard work! I already consider SciPy and NumPy to be best practice in this area but as I'm sure you know, it's the long tail of stuff built on top of these and other core packages that are really the issue!!
