Forced on who, by who? It is the DE/WM people that is driving the thing.

I'd argue that any type system that don't support enforcing non-nil/nullability is not strong in any way and probably worse than not having any type system at all as they give a false sense of security.

The fun part is that the argument holds just as true for humans that write code - we also run tests to verify our work!

Which is basically what people liking dynamic languages have said all the time - types is only good as long as the overhead they bring doesn't cost more.

That is great, but it also sets the stage for actual fiber to be drawn as it is vastly cheaper to connect to an existing end user network than to build it up from scratch. When a critical mass of villages have built internal networks it will be worth drawing cable for them as well.

Lack of sufficient population density and political instability is what would stop this.

I suppose one real upside is that in very regulated areas with only one operator this gives them some baseline regarding service that they actually need to beat.

Trade secrets dont have a time limit.

But if they can pay some people to produce the knowledge they can also pay them to not share it after they change employers. Just like regular noncompete clauses I don't see why this is something that require more than regular contract law or why it should be inherent instead of negotiated for a fee.

No, you can use a memfd.

In aggregate this looks like a godsend, but there are some examples (like foo?.:method) that looks atrocious.

New comment by yxhuvud in "Copper transport drug restores memory and clears toxic Alzheimer's proteins"

It is also worth mentioning that many of the alternative explanations involve brain infection, and improving brain/blood barrier also apply to that.

If you read the actual article you will see this doesn't target the amyloid directly at all, but instead improve the brain/blood barrier and restore normal function of immune system, somehow.

It has a million features I don't use. But some features are really, really nice, like C-q for editing file names (C-x-s to persist changes once done). Rectangle editing is so, so nice to have when renaming multiple files.

Crystal don't have the dynamicity but has macros to get the next best thing. Most meta magic in Ruby in good code are done at startup anyhow so you don't miss out on that much. YMMV.

It is not prohibiting guard rails. It is prohibiting Siri getting preferred treatment to bypass said guard rails

The third option is: launch in a way that is compliant with EU rules everywhere. Except they don't want that as they want to retain their outsized market power.

This is a competition law, not a privacy law.

What are you talking about, DMA has passed in the parliament.
