If you use Box to refer to parent, then parent cannot own the child (unless using things like Arc<Mutex<>>).

The "if I then go and code in Python, Java or C#, pretty much all objects have the overhead of an Arc" is not accurate. Rust Arc involves atomic operation and its preformance can greatly degrade when the reference count is being m

Not allowing take reference can avoid interior pointer. Interior pointers make memory safety harder and also make GC harder.

If I keep removing one element in front and adding one element on back, then normal ring-buffer deque will involve no copying, but this will keep doing copying to empty space, so its performance could be much worse than deque if the queue i

This kind of explains why LLMs are good at making demos and good at writing code under clear specification, but often break existing features in a large codebase. When codebase become large, the signal-to-noise ratio of context reduces.

Software can take a freeride of hardware improvements. GPT wrappers also can take a freeride of foundation model improvements.

ARM already have a special instruction `FJCVTZS` to accelerate JavaScript. If WebAssembly gets popular enough there will probably be hardware acceleration for it. https://community.arm.com/arm-community-blogs/b/arc

In my opinion, the best way of fighting with crawlers is not giving error feedback (403). The best way is to give the crawlers low-quality AI-generated data.

The bugs coming from porting from X86 to ARM may be related to memory order. ARM has weaker memory order than X86. You may need to add memory barriers or synchronization. Of course there are other causes.

A lot of modern AAA games use dithering transparency. It doesn't suffer from ordering problems. Although it looks weird in low resolution, it looks fine in high resolution.

It's not appropriate to say that "having trouble with borrow checker means code is wrong". Sometimes you just want to add a new feature and the borrow check force you to do a big refactor. See also: https://loglog.

In lifetime, subtype means longer lifetime (it's unintuitive). 'a : 'b means 'a is a subtype of 'b, which contains 'b and can be longer. Rust can improve this by introducing syntax like `'a contains '

Someone mentioned "hallucination-based API design" on twitter (I cannot find it now). It's designing API by LLM hallucination. If there is a common hallucination API call, just add that API. This will make the API more "
