This isn’t Linux, but Linux-like. Its a microkernel built from the rust programming language. Its still experimental, but I think it has great potential. It has a GUI desktop, but the compiler isn’t quite fully working yet.
Has anyone used this before? What was your experience with it?
Note: If this is inappropriate since this isn’t technically Linux, mods please take down.
You must log in or # to comment.
I don’t understand the obsession with rust.
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:
- no standard build system, most projects use cmake or meson and vendor dependencies with the projects. These build systems were really hard to learn (especially cmake, meson is easier). There are package managers these days such as conan and vcpkg but there is not really one standard way to build programs like in rust.
- error messages were really hard to understand, especially when the project uses templates
- it felt like 3 languages in one, projects written before c++11 differ greatly from c++11 and up
- some of the new language features have really weird syntax, for example lambdas
- some people say that rust is hard, but modern c++ is considerably harder to learn, just look at the list of modern c++ features: https://github.com/AnthonyCalandra/modern-cpp-features, you have to know the different pointer types (unique_pointer, shared_pointer etc.), templates, rvalue references and move semantic, exceptions, constexpressions and the list goes on
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”.
I know the evangelists can be somewhat overwhelming, but its popularity is not unwarranted. It’s fairly easy to pick up, has an incredibly enthusiastic and welcoming community. People like it because it’s incredibly performant, and its memory safe. In terms of DX it’s really a joy to work with. It just has a LOT going for it, and the main drawback you’ll hear about (difficulty) is really overblown and most devs can pick it up in a matter of months.
The main difficulty I have with Rust (what prevents me from using it), is that the maintainers insist on statically compiling everything. This is fine for small programs, and even large monolithic applications that are not expected to change very often.
But for the machine learning projects I work on, I might want to include a single algorithm from a fairly large library of algorithms. The amount of memory used is not trivial, I am talking about the difference between loading a single algorithm in 50 MB of compiled code for a dynamically loadable library, versus loading the entire 1.5 GB library of algorithms of statically linked code just to use that one algorithm. Then when distributing this code to a few dozen compute nodes, that 50 MB versus 1.5 GB is suddenly a very noticeable difference.
There are other problems with statically linking everything as well, for example, if you want your application to be written in a high-level language like Python, TypeScript, or Lisp, you might want to have a library of Rust code that you can dynamically load into the Python interpreter and establish foreign function bindings to the Rust APIs. But this is not possible with statically linked code.
And as I understand, it is a difficult technical problem to solve. Apparently, in order for Rust to optimize a program and guarantee type safety and performance, it needs the type information in the source code. This type information is not normally stored into the dynamically loadable libraries (the
.soor.dllfiles), so if you dynamically load a library into a Rust program its type safety and performance guarantees go out the window. So the Rust compiler developers have chosen to make everything as statically compiled as possible.This is why I don’t see Rust replacing C any time soon. A language like Zig might have a better chance than Rust because it can produce dynamically loadable libraries that are fully ABI compatible with the libraries compiled by C compilers.
You can load Rust into Python just fine. In fact, several packages have started requiring a Rust compiler on platforms thst don’t get prebuilt binaries. It’s why I installed Rust on my phone.
The build files for Rust are bigger than you may expect, but they’re not unreasonably big. Languages like Python and Java like to put their dependencies in system folders and cache folders outside of their project so you don’t notice them as often, but I find the difference not that problematic. The binaries Rust generates are often huge but if you build in release mode rather than debug mode and strip the debug symbols, you can quickly remove hundreds of megabytes of “executable” data.
Rust can be told to export things in the C FFI, which is how Python bindings are generally accomplished (although you rarely deal with those because of all the helper crates).
Statically compiled code will also load into processes fine, they just take up more RAM than you may like. The OS normally deduplicates dynamically loaded libraries across running processes, but with statically compiled programs you only get the one blob (which itself then gets deduplicated, usually).
Rust can also load and access standard DLLs. The safety assertions do break, because these files are accessed through the C FFI which is marked
unsafeautomatically, but that doesn’t need to be a problem.There are downsides and upsides to static compilation, but it doesn’t really affect glue languages like Python or Typescript. Early versions of Rust lacked the C FFI and there are still issues with Rust programs dynamically loading other Rust programs without going through the C FFI, but I don’t think that’s a common issue at all.
I don’t see Rust replace all of C either, because I think Rust is a better replacement for C++ than for C. The C parts it does replace (parsers, drivers, GUIs, complex command line tools) weren’t really things I would write in C in the first place. There are still cars where Rust just fails (it can’t deal with running out of memory, for one) so languages like Zig will always have their place.
Is it not possible for Rust to optimize out unused functions as with C? That seems …like a strange choice if so.
Is it not possible for Rust to optimize out unused functions as with C?
No Rust can do dead code elimination. And I just checked, Rust can do indeed do FFI bindings from other languages when you ask the compiler to produce dynamically linking libraries, but I am guessing it has the same problems as Haskell when it produces
.soor.dllfiles. In Haskell, things like “monad transformers” depend pretty heavily on function inlining in order to achieve good performance.So I am talking more about how Rust makes use of the type system to make decisions about when to inline functions which is pretty important when it comes to performance. You usually can’t inline across module boundaries unless modules are all statically linked. So as I understand it, if you enable dynamic linking in your Rust program, you might see performance suffer a lot as compared to static linking, and this is why most Rust people (as I understand it) just make everything statically linked by default.
I am not sure that is quite right. I dont think rust support just enabling dynamic linking of its dependencies. It can talk to dynamically linked libraries - which is how FFI works. And you can compile rust crates to be dynamically linked. But when you are going down this route you are talking over the C ABI. This requires some effort on the code author to make their APIs exportable to C types and means you lose all safety when talking over the C ABI.
I also dont think that rust inlines across a crate boundary unless the function is marked as inline or LTO is enabled - inlining across crate boundaries is expensive and so only done when explicitly needed or asked for it. It is more that you lose features like generics and traits and other things that are not supported over the C API.
Do you need inlining if you just use fixed monad transformers?
Do you need inlining if you just use fixed monad transformers?
I am not sure what you mean by “fixed” monad transformers, if you mean writing your own
newtypewhere the functor variable is the only type variable, essentially what you are doing is hand-inlining the monad transformer, and so no, if you inline by hand, then the compiler doesn’t need to do it.Haskell inlines all
newtypedefinitions automatically, so if your monad transformer has all of the type variables bound (except for the functor variable, because that is a special case the Haskell compiler is specifically designed to handle) the compiler will usually reduce those to ordinary lambda expressions automatically, and lambda expressions usually optimize to the most efficient machine code.The only time the compiler cannot reduce a
newtypeto an efficient lambda is if the non-functor variables, e.g. the state type variable or the exception type variable, are unbound. Those values could become anything at all at its call site, limited only by the constraints set by the type context. So the type context information, a lookup table of type class instances, must be associated with that lambda expression, and in order to do that, the compiler must create a closure around those values. Creating closures allocates values on the heap, and this is much, much slower than efficient lambda expressions, and no faster than allocating a data constructor as with Free Monads.Alexis King did a presentation on it where she explains all of this extremely well, if you are interested: https://youtu.be/0jI-AlWEwYI
It is a bit long, but at 17:40 or so she starts talking about strategies for how monads and effects can be implemented in the GHC intermediate code, and compares Free Monads and effects to monad transformers. At 21:15 or so she begins to explain how
newtypetypes can be optimized away completely,newtypeconstructors don’t exist at all in the low-level code, they are a “zero-cost abstraction.” On the other hand,dataconstructors (used for Free monads and effects) always allocate something on the heap which is an order of magnitude slower.Then at around 27:45 she begins to show how
newtypeswith type variables cannot be inlined across module boundaries for the reason I explained above (type context tables associated with closures), and so monad transformers cannot be optimized across module boundaries.Yep, I mean like
newtype MyT m a = MyT (ReaderT MyEnv (StateT MyState m) a). But one can useReaderT MyEnv (State MyState m) adirectly as well.I found the MTL style (tagless final) a bit problematic anyway, so I wanted to comment about this.
It is and it does.
So you’re working on your machine learning projects in Zig?
So you’re working on your machine learning projects in Zig?
No, Python and C++, which were the languages chosen by both Google and Facebook for their AI frameworks.
I just think if a systems programming language like Rust does not provide a good way to facilitate dynamic linking the way C, C++ does, these languages will start running into issues as the size of the compiled binaries become ever larger and larger. I think we might all be a little too comfortable with the huge amount of memory, CPU cycles, and network bandwidth that we have nowadays, and it leads to problems when you want to scale-up a deployment. So I think Zig might make a more viable successor to C or C++ as a systems programming language than Rust does.
That said, I definitely think Rust and Haskell’s type systems are much better than that of Zig.

And the fucking MIT License
Yes, as much as I appreciate memory safety and rust in particular. I’m very worried by this pivot away from copyleft and GPL. Specially the rewriting in rust phenomenon of fundamental stuff. It’s safer, yes, but they’re all pretty much non GPL and it seems very risky to me. Make no mistake, the industry is riding this wave to move away from copyleft to permissive licenses.
I wish that people understood the importance of FSF and GNU
Well that is rather insidious. Crap. They probably understand the reasons for the GPL very well. Doesn’t mean they support them.
I’m sure there’s some community pull as well, because most of the rust ecosystem seems to be converged on MIT. But what despairs me is the wilful sidelining of GPL and everything GNU by some open source community members/corporate people. So yeah, you’re probably right
You make it sound like a conspiracy. Just accept that some things are organically more popular, like MIT which is very easy to understand and use for normies. It’s not perfect, but that’s how it is
MIT is a terrible license that only got popular because of the popularity of the anti-open source movement in the last decade.
one could write books about what’s wrong with the MIT license.
It could even theoretically be argued that MIT has in some ways allowed big tech companies to proliferate, by effectively allowing them to take open-source code, modify it, and then close it off in their proprietary software. What does this mean? It means that the work of countless dedicated open-source developers can be co-opted by companies that have done almost none of the work, reaping several billions of dollars, while the developers who actually did the work make no money. It’s like opening your doors wide only to have someone come in, take your stuff, and sell it back to you.
In contrast, in licenses like the GPL, there’s a requirement that if you use GPL-licensed code and modify it, your new code also has to be open-source under the GPL.
I love the free software ideals, but I think we’ve got a different understanding about what constitutes a good and a bad license. What many people seem to forget about software licenses is that there are these other countries besides America. They couldn’t care less about whatever judges rule over there. A good license is a dumb simple license that anyone can enforce in court with ease. A bad license is a convoluted license that crumbles like a house of cards in court. I read the GPL. It’s convoluted. It’s an opaque terms of service agreement riddled with legal boilerplate disguised as software license. A poor execution of the ideals I hold. I only use the GPL as a formality to say that I support the free software ideals, but I have zero confidence in enforcing the GPL.
I’d like to correct you by saying that GPL is DEFINITELY enforceable in countries other than america. I can’t say about every country (tho that will be the case with every license), but for instance it’s definitely enforceable in europe. For example in Germany and France there have been a few lawsuits that the FSF helped carry out against immoral companies.
If you’re in Germany the Institute for Legal Questions on Free and Open Source Software is a law firm that literally works only on enforcing the GPL, FOSS licenses and other technological human rights that are being ignored by big tech.
If you want to be even more sure about European Enforcement you may want to checkout the EUPL v1.2 which is GPLv3 compatible.
In other countries, such as Japan, the GPL is also enforceable, so long as you treat it the same way as copyright, so you’re willing to sue companies that you know are stealing from you (the FSF can help you if you can’t afford it).
Russia and China don’t care, but… it’s Russia and China, that’s not really news, is it? :)
EDIT: I will write a full article about the legal enforce-ability of FOSS licenses such as the GPL before the end of the year
Rust devs be like:
Shame that we don’t have a proper copyleft license tho? GPL, as nice as the intentions are, is a license so convoluted that I’m not sure whether it’d hold up in court in my country.
It’s a system programming language that isn’t C or C++.
Edit to add: How did Go get on that page? That’s a stretch.

- breaks compatibility

- hard to add without breaking compatibility
Then we arrive at Rust as a natural outcome.
And it’s of course possible to migrate to Rust from C or C++ progressively, fish has almost got it done.
Did fish migrate progressively tho? I thought they swap out everything at once as soon as the rewrite is ready
Well, they are not going to release in between, but their rewrite still “works” at each commit being a hybrid of Rust and C++.
Ah, alright
Rust isn’t just a new improved version of C or C++. It’s completely new and it feels completely different to use Rust. In a positive way
(notice: I am not a Rust or C/C++ expert)
Doing all that is creating a completely separate programming language from C. Rust is that programming language.
Fix shitty imports
Rust does that with modules and crates.
Improve syntax rule
You mean having consistent/universal style guidelines? Rust pretty much has that with rustfmt.
Improve memory management
Safe Rust is memory safe (using things like the borrow checker), and Unsafe Rust is (usually?) separated using the
unsafekeyword.Although Unsafe Rust seems to be quite a mess, idk haven’t tried it
Other new misc features
Rust has macros, iterators, lambdas, etc. C doesn’t have those. C++ probably has those but in a really weird C++ way.
deleted by creator
I’d say no. Programming safely requires non-trivial transformation in code and a radical change in style, which afaik cannot be easily done automated.
Do you think that there’s any chance to convert from this to this? It requires understanding of the algorithm and a thorough rewrite. Automated tools can only generate the former one because it must not change C’s crooked semantics.
deleted by creator
I think there’s no need to stick with one particular language. It benefits to learn more languages and bring the “good parts” of their design into your code whatever you are writing it in.
Btw It happens that I’ve learned a bit of RISC-V, with Rust.
Guaranteed memory saftey
C and C++ can’t be fixed retroactively because old code must remain compatible.
If you’re going to implement your own C dialect, you may as well just write a new language.
For C++ that’s Rust, for C that’s probably Zig (Zig will just let you import existing C files, which helps with porting). Carbon and experimental languages like Jakt may also work, it all depends on what your priorities are.
Idk what the iso fuck up and I don’t code enough to appreciate whatever technical debt exists in either so I am probably sound like an idiot but…
Since I do infosec, the glaring issue for me is not being memory safe.
Conservatives always loose, especially in tech
The idea is less bugs due to stricter rules when developing and compiling. You can understand that.
Then, also more access to build tools and high level programming without changing languages.
If you have no need for that, then just know others do and it’s a great thing.
I’m not against Rust, per se, the idea of a systems programming language with some more advanced memory safety features sounds nice, but what is with the emphasis on creating a Rust version of everything? Like why should we want an OS written only in Rust?
People keep saying this but Rust is not only about memory safety. It’s not C with memory safety sprinkled on top. Compare with C and C++ it has better tooling and dependency management, it’s easier to create modules and organize your code, it’s easier to write tests and it has loads of nice, modern language features like algebraic types and typeclasses. Because of all this Rust is growing fast and a lot of people like it. Writing things in Rust is a bet that more people will get behind them and you will be able to add more features faster to them than to existing projects in C. The idea is not to simply do the same but in Rust. It is to have a cleaner, easier to approach codebase that will allow to grow faster in the future.
It would certainly be interesting to see if an OS written in Rust can end up being notably more reliable and secure. My curiosity is piqued by the features you mention.
Yeah, but I don’t know any other language where the fact a program is written in that language is used as a selling point. I never cared that Linux was written in C, I cared that it does its job. I’ve heard about Redox many times, yet never once has there ever been anything said about it other than “it’s written in Rust! :D” Literally, the fact that it’s a UNIXY operating system written in Rust is the first thing about the OS on their home page.
Hey, Linux started as a learning project, you learn more about programming by writing code, so I’m not saying it’s bad, I just can’t understand why I’d care about something that at this stage seemingly is just a learning project.
But it happens all the time with other languages. Especially when that language is newer or in the headlines. NodeJS/Electron was a big one a few years ago. Ruby/On Rails a while before that, have seen it for python programs and way back in the day when java was all the rage.
Personally I think it does matter and as a end user I do care to come degree. It tells you some things about the program, like how it can be install/run what deps you might need, is it going to be a memory hog or possibly full of vulnerabilities. The language affects all of these things, more so when the projects are new or niche and have not been hardened over time or been properly packaged yet.
Personally I love it when a program is written in languages like rust or go as it means I know it is going to be easy to build/install and distribute given they build into single binaries and very easy to make static. But if I see one written in nodejs with electron I am disappointed as I know it is going to be a huge package that consumes large amounts of memory. Or if there is some python package that is not already packaged by my distro I would avoid it as I hate dealing with python dependencies and its virtualenvs.
And for this case, with redox. Well redox is not an application to be used by people. It is a showcase about what can be done in the language. It is not intended for most people that hear of it to ever run it or even want to run it. Yet is very impressive what they have managed to do in it. Including having parts written for it be able to work standalone in Linux and other OSs.
I’m looking at how many of the bugs and security issues are due to memory unsafe code - it’s A LOT and new ones come up almost daily. Humans are just bad at writing safe code because we are so fallible. So if we can eliminate a significant percentage of these bugs from the ground up that suddenly becomes very interesting. Besides personally after two decades of C and C++ (and debugging them) I find Rust much more pleasant and “ergonomic” to use.
If we want an OS to be more secure by design we really have to begin at the most basic level. It might never be perfect but we can greatly reduce the attack surface. This is also why Microsoft is rewriting a number of vulnerable system components of Windows in Rust.
So why is it important to the end-user? Well, if that’s Average Joe, maybe not but Redox OS right now is not mainstream, it is for us nerds who are interested in a safer OS and to see what can be done in that space. Maybe you don’t care and that’s fine, but some of us do and just like any post here, people can chose to skip over it or dive into the discussion, we can’t guarantee that all posts or projects are interesting to everyone :)
That’s fair, I’m just saying it’s not “OS with memory safety” but “OS written in modern language”. I guess it’s interesting in itself but yeah, definitely not groundbreaking.
Some thoughts:
- Testing the capabilities of rust and proving what rust is capable of.
- Seeing what rust is not capable of and proposing improvements for the rust language and ecosystem.
- Trying new OS concepts. Linux for example is strongly backwards compatible. Starting a new OS is the opportunity to do things different and maybe better.
- Maybe it will turn out, that the memory safety will improve OS’. We will only know for sure, if we try it.
Eh, I welcome the iteration. It gives people a reason to practice and hey, who knows, maybe they’ll come up with something neat while rewriting curl or something
This is one of my main gripes with the rust community. What programming language you used shouldn’t be of any concern to the end-user, let alone be put in the tagline.
Rust is a very good and capable language and I enjoy using it. I can’t wait for the day it overtakes C or C++. But I want to know more about the program I’m using other than that it was written in a popular language.
“Written in rust” is basically a meme at this point.
This is typical of when a language is the new hotness. It eventually dies down, either because the language becomes endemic or it fades away.
not necessarily about the language, but things periodically getting rewritten or re-implemented is a useful exercise. it’s a moment for reflection and analysis of the structures and systems as a whole
Rust is used by modern people to create modern programs. If the program would be in C++ for example, a very complicated, error-prone language, that gives me insight into how well (or not) that program might be supported in the future
Rust has characteristics that basically represent a value proposition for the user. An OS that can be higher performance, better at concurrency, more robust, and more secure sounds pretty good to me. They could make those claims and I could not believe them or they could tell me it is written in Rust and I would hope for all of them.
Of course, the language is not a guarantee of anything but it does tell you something about the tailwind that this project will have.
Python implies a bunch of things as well. None of those things make it sound great for an OS and I would assume the worst if an OS project told me they were using Python ( for the core ).
Personally, I am very glad that they tell me the project is written in Rust. I am sorry it bothers you.
It sounds like a elective complaint about Rust though as most OS projects tell you the language up front including C and C++. C++ seems especially eager to announce itself as a superior choice to C. I have not done much research but can tell you what language even most commercial operating systems are written in as they are usually pretty open or even vocal about it. Sometimes they are proud of what the did not pick ( see Linus opinions of C++ for example ). Haiku and SerenityOS, in contrast, brag about C++ and have even made YouTube videos about it.
It is not just OS projects either. I mean, why does GitHub display the language used as a standard project feature after all?
Carcinisation is inevitable
- Ferris
The language is newer so it does a lot of things better than C, C++ and even higher level langs like java. It is more probable that people in the future build upon Rust than legacy languages.
Comparable to how it would be misguided now to start a project that only runs on Xorg
Languages are easier to work with the bigger the ecosystem.
I’ve been installing a lot of things written in rust recently, and I’ve noticed a trend between them. They’re all stable, fast, and very user-friendly. I don’t really have to fiddle with them nearly as much. I think there’s a lot that goes into this, but it really boils down to: rust is safer and prevents huge categories of bugs, it’s incredibly stable and requires less debugging and maintenance, it has extremely high level abstractions to make development quick and less verbose, and it has the best tooling I have seen for any language. It enables developers so effectictively that the things that are usually tedious and difficult become easy and potentially mandatory, and so you just get better software.
I know that sounds pretty abstract and opinionated, but having used the language for several years now, and especially coming from Java, I have really felt an incredible difference - I stopped having to constantly fix breaking Gradle builds and JVM version management, I stopped getting null pointer exceptions, and I had much more powerful tools for building abstractions. When you see how much control and power rust gives you while still keeping you safe, it’s just night and day compared to the especially old languages like C.
Basically, anything written in rust will be better if it can enable developers to spend their time working on useful features instead of fixing bugs, fiddling with build systems and fragile legacy infrastructure cobbled together from dozens of third party tools.
Now imagine the new COSMIC desktop environment in Rust on Redox, that would be great
Why would that be great? It’s so weird that people care this much about what language their OS is written in…
Rust is a memory-safe language. So in this case, it could result in more stable software.
I personally like rust, so I get excited when cool things are done with it because each one makes rust just that much bigger, which leads to it being made that much better.
I see projects like that as more of a statement that “rust can do it” than anything.
I want the newest, best software. Is that uncommon? Modern rewrites are often much better than their age-old counterparts since the tech got better over time, compare for example grep vs ripgrep, or find vs fd. The rewrites are much faster and user-friendlier
Memory corruption bugs account for a majority of cve’s in the linux kernel
Probably inevitable considering Jeremy Soller is the lead dev on Redox while also currently contributing to COSMIC.
To be honest, I’m surprised COSMIC isn’t the default, but it’s likely due to display server stuff that isn’t part of Redox (Wayland, etc.).
This is already in progress. COSMIC applications are compatible with Redox OS.
I’ve used it in a VM just to mess around. I’d like to install it on an old ThinkPad and try to compile some applications.
Oh my god they rewrote Linux in Rust. Amazing.
Kinda. Redox uses a microkernel architecture and tries to keep only the most important functionality in ring 0 while they push everything else in userspace. It’s great.
So they actually rewrote The Hurd in Rust.
Many lessons were learned from the Hurd that has impacted ALL microkernel kernel and userspace designs, but it is ancient by today’s standards.
Its more accurate to say they were “rewriting” MINIX, but I don’t like the word “rewriting” as all of these systems are unique in their own way.
How long would it take to compile their Rust microkernel alone compared to a similar one done in C? There are many posts around the web complaining about Rust’s long compile times, though thankfully rarely as slow as C++
I wouldn’t say it’s inappropriate as there is more and more rust making it into the native kernel. I’ll definitely throw this on my Ventoy usb and see if I can get it to boot
Having some hardware mentioned on the site that is supported and ready for use could be helpful if someone wants to try it (say raspberry pi), There are probably people who are worried to will make their computer explode.

The fact that they support any real hardware at all is impressive. A lot of experimental OSes (I’m think of Serenity in particular) usually only support whatever hardware Qemu is emulating, and maybe a couple other things that are partially supported that a developer played around with a few times.

If it weren’t “written in rust” nobody would give a shit.
I would definitely give a shit even if it was whole OS written in JavaScript.
So?
My exact response when reading the title.
Do you think other people do things simply because they think you will care?
I’ve heard about it due to the Ion shell which I tried out once
Ion’s been my go to local scripting language for a while
Shame they don’t have a list of the packages they offer.
It’s a bit hidden in the FAQ, but here you go.

Slap a Firefox on top (and time travel to when ff is all rusted) and we’ll be coming for ChromeOS. But will windows be completely rusted first? 🙃
I think the main reason Firefox isn’t on there is because redox os doesn’t use Wayland and x11. Porting firefox would be a massive effort unfortunately.
Rust needs to fix an epic tonne of issues automagically to compete with a kernel that’s had millions of debugging hours on it, irrespective of language. Yes, Rust removes a whole class of errors that can occur in C, but I doubt it removes so many that it can compete with the wide, decade long usage patterns the Linux kernel has been through.
