Is this “just” a 20% project or is this more significant (like Android one day supporting Rust to develop apps)? And I haven’t looked at everything yet, but it suggests to install Rust like this: sudo apt install cargo rust-src While everyone I know uses rustup^: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh ^ https://rustup.rs/

I'm tired of installation instructions that consist of "curl | sh". Especially since this one just tries to detect the platform and downloads the correct installer for me. I know what platform I'm running, and I don't want to pipe the internet to my shell. In the end this is unpacking a tarball in ~/.rustup, I don't need the risk of running some bespoke script for that.

Since the ultimate objective is to run a binary blob that you just downloaded off of the internet, piping a script to your shell over HTTPS adds no additional attack surface.

This is because people are tired of figuring out seventeen (hundred) different package managers that may or may not work and that may or may not accept your package into their repo?

To be honest, the course suggests using apt since that's an easy security-approved way to install things on our computers (see https://en.wikipedia.org/wiki/GLinux).

I'll be happy to update it to suggest using rustup like "normal". Could you make a PR for that?

Actually, there is already an issue for this: https://github.com/google/comprehensive-rust/issues/19 and I hope someone will fix it soon :-)

It's slower then C for sure. But slower then C++? I doubt it.

Rust is most comparable to C++ with heavy TMP, as it itself also makes use of templates.

To be precise, Rust generics perform monomorphization, which C++ templates also perform. But I wouldn't go so far as to compare the language to "C++ with heavy TMP", as that's far too broad of a characterization; TMP implies a lot of things, e.g. poor error messages, that Rust doesn't necessarily exhibit.

The first thing I implore everyone to do when evaluating Rust is to check out a non trivial project and start hacking on it. I have always found the compiler to be unacceptably slow in these cases, especially if you come from C rather than C++. If you work your way up from Hello World you may not ever notice this until you already invested a substantial amount of effort.

Could you point me towards a project where this is the case? I want to try it out as I never found Rust slow to compile.

“I’ve never been bothered by the compilation speed” is not the same thing as “It isn’t slow to compile.”

It's kind of surprising to see that Rust is so rapidly accepted by wide range of developers.

Unfortunately I'm from DataScience field, so I cannot see much motivation to learn Rust, but I am considering learning it, because language itself seems exciting!

Is there anyone on HN who is from DataScience field like me and has learned Rust? It would be much appreciated if you could share the experience.

No not at all.

…perhaps you lack experience of a time where fixing bugs that cannot be effectively discovered using tools available in other languages took less time than the equivalent code in Rust would take to compile?

Yet all the tools that exist still don't prevent memory safety bugs found regularly in pretty much any C codebase. Using safe rust will be a productivity boon because of its type system, crate ecosystem and memory safety.
