From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

From my personal experience I can tell you 2 reasons. The first is that this is the first general purpose language that can be used for all projects. You can use it on the web browser with web assembly, it is good for backend and it also is low level enough to use it for OS development and embedded. Other languages are good only for some thing and really bad for others. The second reason is that it is designed around catching errors at compile time. The error handling and strict typing forces the developer to handle errors. I have to spend more time creating the program but considerably less time finding and fixing bugs.
That sounds pretty great. I get sick of having to switch gears for every layer. As a hobbyist it is tough to remember five or six languages well enough when only coding something a few times a year.
Since I do embedded, scripting, web front and back end this is sure tempting.
I have been hesitant to try to learn yet another language (this would make...ummm.. idk I lost count ages ago). But with all the hype I may break down and give it a whirl.
Sounds like python may be a better fit if its supported on the embedded devices you use as it will cover scripting and backend too. Rust has quite a learning curve and can be rather verbose.
I do use python quite a bit for scripting and backend, app, and I've used MicroPython a little bit, preferring C, C++ for embedded. It's pretty great for what I need.
I might mess around with Rust out of curiosity anyway, though the downsides you mention make it less compelling for me, personally. I'm not a big fan of verbose languages (e.g., Java, though I have used it for some apps).
Messing around with rust is certainly worth it, as it can change the way you think in a way that improves code in whatever language you write.
If you are curious definitely do check it out! It's a really cool language to learn and you'll start to enjoy the fight the compiler puts up.
Sorry but I don't see the reasoning backing the enthusiasm for python. Sure, it is great for scripting (this includes machine learning), but why for anything else?
An easy language that works everywhere? This person is writing code a few times a year.

I realize that even $2 systems are running full Linux distros these days but Python does not map to what I think of as “embedded”. If you have a full Python interpreter, it is already a pretty rich environment.
That said, this is what computing is starting to look like. There is less and less “bare metal”. I work with people that claim to be “firmware” engineers and then, when you look, you find out they have a full Ubuntu distro running and they may as well be running on a laptop.
I feel like C++ is as competent as Rust for any project and it's definitely older.
Not sure I can think of anything I'd enjoy less than trying to build a web app in cpp
Before using Rust I was using C++ for most projects and while it is a really powerful language there were some big problems:
At least it won't complain about rigid, skolem or occurrence check.
Rust was created because c++ was so bad. Just take a look at crates they need a whole lot less maintenance because less bugs.
My point wasn't that C++ is good. My point was that C++ can and is used everywhere (desktop applications, web applications, OSs,...) and is older than Rust. So I feel that "this is the first general purpose language that can be used for all projects" is false. Probably "this is the first general purpose language that I (and many others) like to use for all projects" is true, but is a different claim.
TLDR: You said Rust was first language capable of system, app and web, it isn't.
It depends on what “can be used” means. I really like C# and it “can be used” for that full stack C# for example can write out native machine code, can manually and precisely lay out memory, and can directly link to assembly language routines. You can write an OS in C#. Even as a fan though, I would certainly argue that it is the wrong tool for that job.
In the same vein, while I know C++ “can” be used for web dev, I would argue that anybody that tries to do so for any significant project is insane.
I am not sure I would use Rust for “everything” but I do think the claim that Rust is one of the first languages where it is reasonable or practical to choose it for any of these uses is valid. Rust code can be very high level and often does not much different than a scripting language. At the same time, it can go as low-level as you want. This article is about an OS in Rust ( and there are few ). Web dev in Rust is totally reasonable and there are a few popular frameworks available. Rust has one of the best WASM stories around.
It is good and rust improves on its gaping weaknesses.
Yeah I never made that claim the threads OP did.
That is definitely a “feeling”.
