  • You can update your version of Fedora through the updater software as well but it’s a very clear separate process that is initiated manually.

    Distro version updates bring major updates to key packages - the one you’d notice most would be to Gnome, the desktop environment. There will be other things too that get only bugfix and security updates during the life of that version, and then after a while that version will lose support and you won’t get any updates at all (https://docs.fedoraproject.org/en-US/releases/lifecycle/).

    Updating is very safe and reliable. I’ve had my Fedora install at work for 3 years, updating periodically and it’s working extremely well.



  • One more note on learning Rust: what Rust does is front-load the pain. If you write something in another low-level “direct control of memory” language you can often get something going much more easily than Rust because you don’t have to “fight the borrow checker” - it’ll just let you do what you want. In Rust, you need to learn how all the ownership stuff works and what types to use to keep the compiler happy.

    But then as your project grows, or does a more unusual thing, or is just handed over to someone who didn’t know the original design idea, Rust begins to shine more and more. Your C/C++/whatever program might start randomly crashing because there’s a case where your pointer arithmetic doesn’t work, or it has a security hole because it’s possible to make a buffer overrun. But in Rust, the compiler has already made you prove that none of that is possible in your program.

    So you pay a cost at the start (both at the start of learning, and at the start of getting your program going) but then over time Rust gives you a good return on that investment.


  • Context: I am an embedded software engineer. I write a lot of low level code that runs on microprocessors or in OS kernels, as well as networking applications and other things. I write a lot of C, I write some Rust, I write Elixir if I possibly can, I write a lot of Python (I hate C++ with a passion).

    I don’t think you want Rust. Python is unbeatable on “idea to deployment” speed. Python’s downsides:

    • Painful packaging/distribution if you want to get a load of people who don’t have Python installed to run your thing (e.g the GUI program we currently maintain for talking to our hardware)
    • Performance under some circumstances. There are some things that are not quick in Python. They’re not always the things you expect because Python actually drops down to C modules for a lot of the number crunching that you might do. E.g. for ML you are basically using Python to plug a load of bits of fast C code together

    Rust is good when you need at least one of:

    • High speed
    • Control over use of memory
    • Low level systems programming (drivers etc.)
    • Can’t cope with a Garbage Collector
    • Compiling to a microcontroller

    If you’re doing one of those and so have become expert in Rust, then it is actually excellent for a lot of other things. E.g. you might build your data processor in it, and then distribution is easy because it’s just a single binary.

    One option you might look at is Go. You get a lot of performance, you get good parallelism if you need it, it’s designed to be easy to learn, and it also compiles programs to a single binary for easy distribution.












  • It’s a core capability, but it’s a lot of work due to all the different types of thing you can post.

    An app that can read posts and write comments is still useful without submitting posts, but an app that can submit posts but not read them is pretty useless. So, when you’re making stuff you do reading posts first, then you do writing comments, then you do submitting posts. That makes sense, right?

    Let’s say it takes a few weeks to do each, and you’ve got to the stage where you’ve done reading and comments, but not submitting. That’s useful already! You’re not done, but what you’ve got is still useful for people and people want it, so why not release it at that point? Then carry on working and release the remaining features after.

    Releasing as early as you can is good for everyone - the developer starts getting income for the work they’re doing, they learn about bugs and issues earlier in the development process and we get to start using it sooner. For me Sync without submitting is still better than the other apps, so I want to use it.


  • Everything=all but there is a Lemmy oddity here.

    Everything shows everything for all the communities subscribed to by anyone on your instance. So it might be different from one instance to another because the users have subscribed to different sets of communities.

    It’s likely to be a small difference between two big instances (lots of users so most communities will have at least one subscriber), but if you self host an instance it’ll be pretty useless.
