Kids, I'd suspect. More and more of them are stuck exclusively on tablets.
From what I can tell, there isn't even a version of Roblox Studio available. Scratch seems to work though.

I’ve noticed most of the people we hire these days for dev roles have no idea how computers or operating systems work. I’ll have someone with a pretty impressive title reach out to me with a basic OS question, and I wonder how they got to where they are without this foundational knowledge. Most of this stuff I learned on my own when I got my first computer.
I have no idea if they really never learn and wing it until they become managers or become great cloud engineers who simply scale up instead of running strace.
I dislike that the two are conflated.
Firstly, Mac and Windows both offer a very mature command line interface.
But also, I don’t think knowing Linux should require you to know the command line either. If other operating systems don’t require it, neither should Linux.
If you’re focusing on “developer tools”, even then, what tools do most devs need that can’t be done from a UI? I live a lot of my time in the terminal but there’s very little that can’t actually be wrapped in a UI
But I think they can also obscure functionality the same way as a GUI tool.
Take git for example, it’s much easier to visualize how it works from a GUI. Squashing is also faster in a GUI. But some other operations are clearer when you’re giving every flag yourself.
Ultimately I think it comes down to the UX of something regardless of the form of UI it’s presented in.
I’m very familiar with Linux. My day job for years was Linux based and I honestly do not think one needs to know it, or any other OS specifically , unless your job specifically requires it.
Assuming the discussion is about a typical developer that runs code that is deployed to “the cloud”, and the cloud is basically 99% Linux, yes. You absolutely need to know enough about how Linux actually works to be effective at your job. Otherwise you’ll fall into the sort of trap zillions of “big data” engineers fall into, where you spend countless hours writing custom code that takes up terabytes of RAM that could have been a simple sed/awk/grep pipeline that uses a handful of kilobytes.
It doesn’t specify a job and that’s exactly what I’m calling out.
Even your response assumes that a “typical” developer is one who deploys to the cloud , but what is that based off of? And how many of those need to interact with the cloud infrastructure itself?
Your second point about taking up terabytes of RAM doesn’t really matter if it’s on the cloud or not, and certainly doesn’t matter if it’s Linux . It’s also assuming that you can’t have a UI frontend that just calls the necessary efficient code or CLI commands behind the hood.
So my question remains: what percentage of jobs actually require you to know Linux specifically?
We can apply the principle of charity and assume that because OP was making this complaint at all, it was probably in the context of jobs where ostensibly there is plenty of value in learning Linux. You don’t need to ask for qualification here, it’s just assumed by context that, for OP’s point, these were probable roles that really should have Linux knowledge.
But you turn that around and say “but why would you need Linux knowledge??!”, taking the least-charitably-possible interpretation of OP’s comment, as if they’re talking about janitors or something, challenging them to prove why the majority of jobs (!!??!!??) needs Linux knowledge.
I dunno man, maybe because in their head they’re referring to a category of people for whom working Linux knowledge really should be expected, and it’s assumed that readers of their comment will probably understand that, and that they’re not going to be prompted to qualify every last thing they say.
But sure. Yeah. Linux technically refers only to a Kernel and not the whole OS so people shouldn’t say “learning Linux” if they only mean a CLI and a basic unix-like environment. You’re very smart, thank god you’re here to clarify all of this for us.
I need to stop with HN for a while, the level of pedantry has gotten absolutely out of control and I’m getting angry just reading this shit.
The phrasing is exactly
> There are people here on this forum openly admitting they don’t see how ‘knowing Linux’ is useful
That could literally apply to any job, especially as a developer.
And then the rest of your inane rant is about something I didn’t say. I didn’t say anything about linux being limited to the CLI, in fact my other comments say Linux is much more than the CLI.m. So now you’re just inventing your own argument to be angry about.
So maybe take your own advice, and give a charitable reading instead of getting angry because you’re unable to make a point. Because not only did you take the least charitable version of what I said, you invented arguments I didn’t make.
And maybe you should take a break from the internet if things make you this angry this easily.
Now, talking about people who actually deploy code to backends... these are the folks I had in mind. I imagine most of them don't deploy to Windows Server and they sure aren't deploying to any macos backends.
Why would a frontend dev need to know how to configure a http server beyond what node or wamp/lamp gives them?
The number of full stack people is very low compared to dedicated backend and frontend folks. People focus on the needs of their job, and if their job doesn’t require wearing both hats they usually don’t go out of their way to do it.
Even at many companies that deploy things to the cloud, they’ll have dedicated folks for that because the people writing the code to run are busy writing the code.
That it eventually runs on Linux is not very meaningful to most devs unless their app needs special compiling configurations or libraries.

And this is the root of the problem. A week's worth of coding sure saves them a day of configuring their host systems, not to mention optimizing their cloud spend up. The folks who actually know how the system works and how to diagnose when it doesn't are in short supply and are also effin busy.

This is true only until it isn't. There can be times of coasting and then the dreaded base image version bump comes and 90% of the organization has no clue if they're impacted or how to check if they are.
And all the stuff you mentioned can be done by learning those skills on windows or Mac. Linux doesn’t really need to factor in, and now you’re saying to learn an entirely new operating system in addition to a new skillset.
You’re trying to say they should be more than what they are, but for a scenario they can’t predict coming up? In which case any number of other things might happen too, and there is likely already a team of people better suited to handle those issues. What would the sales pitch be to have someone learn it?
I think there’s an impedance mismatch between what you expect to provide value to someone as a hypothetical future goal and what they actually need to achieve their objectives.
Linux is important if that's what the backend deploys to. If it is, it's a part of the operational envelope - I am saying engineers should have familiarity with what production is running on. I don't particularly care where those skills are being picked up as long as you know that on the production box there's strace instead of dtruss and you know how to check what the D state process is waiting for or whatever interesting issue arises which only happens under load, with networked storage and with at least a couple dozen cpus. (This is also why I don't care for frontend devs to 'know Linux', but having some knowledge about HTTP and their production HTTP servers would be beneficial, as would be knowing that networks aren't magic...)
It's great because we as parents can give our kids a huge boost by guiding them to learn on their own. Look up 'learned helplessness'
The last part is making sure we teach our kids never to work for less than twice as much as everyone else.
