No. Not according to the classical definition of age which is the time since birth. I was born a few decade ago. My grandparents are decades older then me. The earth in millions of year older than me. And the galaxies billions of lightyears

Maybe he is talking about exception safety. vector::push_back could throw an exception. But this is far fetched because people doing manual memory management don't usually rely on exceptions, and just abort the program when this happen

This is a funny argument against nuclear. Some nuclear reactor have to shut down for a few days to avoid heating the rivers is a big problem. But the solar panel being down more than half the time (night or clouds) and the wind turbine also

Radioactive, dangerous chemical, ... And the thing is that these are actually harming the people who are near the area where they are disposed, so the harm is more direct. CO2 is more like a global problem, so not as worrisome for the local

Looks like a mix of Rust and C. Like a French person trying to speak English, but still saying half of the words in French.

(Not a physicist myself) Blackholes are just a solution to Einstein equations for an object in which all its mass is concentrated in its Schwarzchild radius. Protons and electrons are bigger than that so they are not Blackholes and they wil

Unwrap is supposed to be used when the developer know that the error can't happen. Or that if that error happen there is no recovery anyway, and the best thing to do is to abort the program.

I don't think you can compare the rust dependencies and #leftpad. Crates.io don't allow to remove packages. Also dependencies don't tend to be 10 lines of code only

The alternative is to write the feature yourself. Probably not better from a security point of view. And you have to maintain it yourself.

Of course you can call drop() manually, but almost nobody does or even think about it because that's not the way you program in a language with RAII. Don't get me wrong. I do think that rust and c++ RAII is much more convenient an

But it is. If you have a String on the stack, it's memory is only reclaimed at the end of the scope, while it often could be free'd before. This is especially bad in async code around await point since it means the memory need to

And you can do the same with the Rust dependencies (with cargo-vendor for example) Cargo has even an --offline flag.

Strongly disagree. Science is based on fact and whether models fits observations. Politics and core values is more like fashion and there is no right or wrong. See also https://en.wikipedia.org/wiki/Is%E2%80%93ought_pro

The current version (6.3, just released) is free and open source. You must be confused with the LTS which is the commercialy supported version. And yes, if you want a commercially supported version, you have to pay. Isn't that normal?

How do you not emit CO2 when producing cement? The only way to be carbon neutral is to "offset" it by having some carbon capture industry to somehow remove the equivalent of CO2 from the atmosphere.
