Mild counterpoint. Our professions(all things IT) moves bloody fast.

If I were looking for info on cooking, baking, knitting sure... but IT stuff, I opine many of us seek the latest info because of the breakneck speeds this profession is known for.

Some areas do, some areas not so much.

I have a colleague that's incredibly strong with databases (we use a mix of MySQL and PostgreSQL) and he's living off the learning he did 20 years ago when he was a junior Oracle consultant.

I live off the learning I did in Linux now that I administer Kubernetes clusters for a living. Once you get past the "cloud native" abstractions (and other BS) it's penguins all the way down, and I get to reuse most of my core Linux competencies I learned 10+ years ago (eg: I do tcpdump in prod, and it's quicker and more effective than many of the modern shiny tools).

It still does change and you have to adapt.

E.g.

> databases (we use a mix of MySQL and PostgreSQL) and he's living off the learning he did 20 years ago when he was a junior Oracle consultant

And there's lots of changes here, e.g. vector stores, all the different query engine improvements, PostgreSQL IO improvements, etc and they all may impact your job. Your optimal query back then might not be the same. Living off the old learnings is like taking a 50% discount on the max potential.

> I live off the learning I did in Linux now that I administer Kubernetes clusters for a living.

And these have had changes consistently too e.g. io-uring and gateway api. You can only be in legacy for so long.

One thing this comment (and recruiters) don't understand is that someone with foundation can learn these things pretty fast within few months.

		> can learn these things pretty fast within few months. This totally misses the point. You can learn anything pretty fast in some ways. The point of what my comment replied to was about not learning at all. It was about learning something some years ago and letting it sit like interest in a bank without investing further.

For udemy classes though it is hard to know what is timeless knowledge vs what is outdated crap starting out.

That is why there isn't much else to go but the heuristic of the most new class with the most ratings.

		True, but sometimes you need a cheap course about some seasonal garbage. A few years ago i happily spent 12€ on a course about gitlab ci that saved me quite a bit of time reading documentation and got me started within an afternoon. I had no previous experience with gitlab, but i was well versed with git. Those were money well spent, for example.

Does it though? I mean I'm still teaching thread-safety and recursion to my interns... a solid foundation is a solid foundation.

Yes. The autodesk fusion course that I learned 3D printing design off of on Udemy had a bunch of instructions for UI elements that had moved in the application.

It wasn’t a big deal but I would have still appreciated it if the author inserted some new recorded segments or re-recorded some content to make up for it.

I think you are confusing interiorizing some fundamentals with things moving fast. There are languages and frameworks rolling out higher level support for features covering concurrency and parallelism. While you focus on thread-safety, a framework you already use can and often does roll out features that outright eliminate those concerns with idiomatic approaches that are far easier to maintain. Wouldn't you classify that as moving fast?

But are you teaching the basics of programming with 30 year old textbooks? Can you learn the principles of web dev by building like they did 30 years ago? Sure. But it will be a pain in the ass vs using something that is up to date.

For the fundamentals, sure, but many of the top sellers are going to be on things like React, Next, etc.

And in ten years after react is forgotten about, there will still be companies actively hiring Java developers

See you in ten years! We're a hop, skip and a jump from one click automated conversion from every legacy Java app to web and electron desktop compatible code and we can just retire Java entirely. in 2025, Java is not the most performant. It does not run in the most places. it is not the easiest to write or reason about. its advantage over anything else is momentum and it's losing that too.

React is just a formalizatio of a UI update pattern that exists in every app ever made except the ones that are bad. Source: written a lot of java and nobody is currently paying enough to make it worth doing again.

In ten years you'll see greybeards complaining that new kids don't know shit about React fundamentals.

React was released 12 years ago, and since then a few React clones popped up as well such as Preact.

React occupies a very similar place today as angular did back in the day, and angular is on life support, if that.

	▲	locknitpicker 4 days ago \| parent [-]
		I don't know what argument you think you are making. React was released in 2011 whereas AngularJS was released in 2010 and Angular2+, what we actually call Angular, was released in 2014. So your counter examples of popularity are projects what at best started out at the same time as React but unlike React winded down in popularity. After over a decade l, React is not only the most popular framework by far but also is the support framework for a few of the top 10 frameworks. So what point did you thought you were making? That React managed to become the dominant framework whereas your examples didn't?

JS frameworks and chasing AI fads, perhaps. But fundamentals? Engineering principles? How CPUs work? Linux, networking, x86? Stuff that is decades old still applies.
