Developers who are not willing to learn something new and not adapt are the worst. Besides that, nobody is forced to learn Rust, only those who want to work on Rust parts.
Developers who are not willing to learn something new and not adapt are the worst.
And this is why COBOL developers are desperately needed these days: because too many people think that “old” was the same thing as “needs a replacement”.
“Learning something new” does not mean the thing you are learning is new. It just means it’s new to you. One of the best things you can do for yourself as a dev is to learn to be fluid and be able to adapt to new languages, protocols, and technologies.
It’s a well-documented fact that as people get older their fluid intelligence declines.
I’m quickly approaching grey beard status. I recognize that I’m nowhere near as fluid as I was 20 years ago but I make an effort. You have to continually practice fluidity and actively learn things lest you solidify and lose that skill like any other. It’s important to stay fluid because things change and change faster than we all expect.
At the level of organizational architecture, a culture of emphasizing fluid intelligence as the strategy for attacking problems and adaptation causes serious losses of efficiency, and hence fluidity at a higher scale.
Ensuring compatibility with greybeards’ brains is key to long term success, and that means respecting an upper boundary on the rate of tools change.
There’s some truth to that. PHP is still in use and Wordpress is still somehow a behemoth. But the fact is that PHP has fallen out of favor, isn’t used by new projects, and there’s less demand for people with that skillset. So as a dev, it’s important to recognize that tools come and go and be flexible.
This example doesn’t work as well with C/++ since that’s older than most people here (though the language has also gone through iterations) and likely won’t be going away any time soon. But still, in most cases you probably don’t want to use that language for general work. So you’ll probably have to pick up other things for your toolchain (and higher level) work which of course has changed a lot.
The good news is though, that it’s relatively easy to transfer core skills between most languages. Especially the ones with C-like syntax, which is most languages.
Netflix is using FreeBSD for servers. You can’t blame everything they do wrong as being a problem with the new hires. They are using an OS older than Linux that changes more slowly than Linux, simply because it performs the best for their specific application. Rate of change isn’t the issue here.
In fact that’s 90% of what this comment is. Blaming new people and new techniques for problems when you aren’t a part of that organisation and don’t actually know what’s happening.
Working with computers is not the same as working with construction equipment. Some degree of fluid intelligence is needed in this field, no matter how experienced you might be, just like how a surgeon needs steady hands. The people you call greybeards aren’t nearly as old as your father is. We are talking about people who are in their 50s and 40s. They don’t have that level of cognitive decline yet. Likewise some things like ext4 aren’t likely going to be ported to Rust now or even ever. They can keep maintaining them as they are now for the foreseeable future. Plus I don’t want people to have to keep working into their 70s and 80s. At some point it becomes elder abuse. Let people retire man.
C has existed for a long time now. We’ve been trying to replace it for ages, for most of it’s lifespan even. C++ actually was one of the new options at one point. I get it seemed immovable only a decade ago, and I think that has lulled people into a false sense of security. In truth it was inevitable it would have to be replaced one day. It’s already well outlived the life expectancy of a programming language. Just think about Ruby: created long after C yet has already become mostly irrelevant. You talk about the maximum rate of tool change, but C is one of the oldest tools we have, keeping it around would be almost 0 rate of tool change over decades. If you can’t see that C is very slowly dying then you haven’t seen the writing on the wall for the past several years. It’s on you at that point.
We should look back with pride at everything that has been accomplished with C, and just how long it’s been relevant. We can do this while still acknowledging it needs to be phased out gradually.
No one is asking for change that rapid either. Linux started adopting Rust four years ago now. It’s probably still going to have C code inside it for at least a decade from now. This isn’t some quick change, it’s a gradual process. People have plenty of time to adapt, and those who are too old to do so will be around retirement agent if not already dead by the time C is fully phased out.
We of course play plenty of video games together to keep him sharp. We also eat mushrooms, paper when necessary, and he works out a lot. We do all we can, believe me.
Honestly you take more care of yourself and your father than I do. I am only in my 20s and suck at video games. If I took mushies or LSD I would probably lose my mind, assuming it’s all still there in the first place. I suspect there is a good reason why people like me only have a life expectancy of 58 or so.
Lots of good insight there. While I disagree with much of it, I get it.
I’m all for keeping one’s cognitive skills. However it is a fact that this decline happens, and that there is a phase of life where one has wisdom without necessarily having the same raw intelligence they had before. The wisdom is encoded in crystallized intelligence.
Yeah, realizing you have that wisdom is eye opening and it’s actually pretty powerful. I can hunt down bugs by smell now with surprising accuracy. But I’m not convinced it’s mutually exclusive to fluidity. I guess I’m just hoping my brain doesn’t petrify and am battling against it.
That was possible because those machines don’t change too much as time marches on. Because they use a stable platform, his organization was able to do better work by relying on his deep expertise. He could train those younger guys because it was the same platform he’d always used. Same dirt, same physics, mostly the same machines, same techniques, same pitfalls, etc.
It’s a poor analogy for software though. Software is an ongoing conversation. Not a device you build and forget about. User demands change, hardware changes, bugs are found, and performance is improved.
I’m honestly curious what the oldest line of code in the Linux kernel is now. I would be pretty shocked to see that anything survived 30 years. And I don’t think that’s because of enshittification.
This example doesn’t work as well with C/++ since that’s older than most people here (though the language has also gone through iterations) and likely won’t be going away any time soon. But still, in most cases you probably don’t want to use that language for general work.
Why not? Because you won’t be able to hire younger devs? That is a function of this culture of pushing for change in everything.
No, because C/++ isn’t the right tool for every job. If I want to write up something quick and dirty to download a sequence of files, I’m not going to write that in C. It’s worth learning other things.
I have to admit though that the conservative approach is more suited to things like a kernel, aerospace applications, or other things with lives riding on it. But also software that doesn’t change becomes useless and irrelevant very quickly. For instance, running Windows XP is a bad call in just about any case.
But again I’m also not trying to say all software should be trend following. Just that devs should embrace learning and experiencing new things.
C has been around for a very long time. I don’t think wanting to replace a 1970s language, that was old when current gray beards were young is a bad thing. People have had more than enough time, and still have a good decade or two to make their careers writing and maintaining C code. Sometimes things have to change, old people be damned. It’s diatribes like this that remind me the human race advances one body at a time as those holding us back die out.
Edit: also we aren’t talking about people in their 70s and 80s here. Most of these “greybeards” are in their 40s and 50s at most. Linux itself is from the 1990s and is therefore more modern than C.
Why? I mean, I, personally, try to be as polyglot as possible, but not everyone working on the Linux kernel is even interested in doing anything that’s not C kernel code, nor is it their profession.
Learning is key in this field. Being able to learn new things allows you to move from one thing to the next as needed. You also learn a lot from experiencing different things. Other ways of doing things, other points of view, other concepts that you may have not been exposed to before.
It also expands your employment potential and general usefulness. Knowing only one thing will severely limit your abilities.
It also expands your employment potential and general usefulness.
I have already mentioned that programming is not everyone’s profession. Not everyone chooses what they do in their unpaid free time primarily based on whether it makes them a more useful person. I think the very phrase ‘my usefulness’ is dangerous.
I never said anything about someone’s usefulness as a person. Their usefulness as a software developer was the topic at hand. Maybe it’s not your profession but a hobby but the point stands.
I think the very phrase ‘my usefulness’ is dangerous. Are we only worth something as drones?
And yet it’s drones that do one thing and only one thing their entire lives, never learn and grow.
Maybe it’s not your profession but a hobby but the point stands.
To be honest, I’ve hardly ever asked myself how I could best please a potential employer with any of my hobbies. But I recognise that you’re probably taking a different approach.
employment potential and learning are generally problems if you are young. if you are old, the time investment to learn a new language is generally not self beneficial as your time of employability starts to dwindle.
Linux ultimately will have to run into the situation of if the people want the newer language to become the mainstream, they need to be more proactive at the development of the kernel itself instead of relying on yhe older generation, who does ot the way they only know how, as relearning and rewriting everything ultimately to them, a waste of time at their point in life.
think like proton was for gaming. you dont(and will not) convince all devs to make linux compatible games using a vulkan branch. the solution in that front was to create a translation layer to offload most of that work off because its nonsensical to expect every dev to learn vulkan. this would be applied moreso to the linux kernel, so the only realistic option (imo) is that the ones who are working in rust need to make the rust based kernel and hope that it takes off in a few years to actually gain traction.

Middle age software engineer here. Very disagree. Hoping to code until arthritis gets me. My point wasn’t only for employment (more of a perk), but primarily self-improvement and improvement on your craft. The day I can no longer do that, that may be the end for me.
That said, I don’t know what Linux community should do about Rust adoption. I just wanted to point out that I think it’s very important for all devs to be able to embrace learning new things and expand and refine their skillset.
One problem is (even Linus acknowledged it in some interview, sorry I have no source) that in future C might no longer be the popular language to learn. I mean learning basics is one thing, but getting good at C and writing in the Kernel, while trying to dodge memory issues is a huge task to ask.
Lot of people learn Rust instead for systems programming today. Meaning in future it might be very useful to get new people into Kernel programming. And as said before, those who are not interested into Rust are perfectly fine using C. The Kernel is huge! Even new code in C is allowed, so this is not something that is going away. Remember, its an addition to the base, not replacement.
The situation of COBOL has nothing to do with Rust in Linux. C is not replaced by Rust, first. Secondly, there are legitimate reasons why Rust was introduced, as a secondary language. You are conflicting two different cases that are two different problems. It’s not replacing a language.
Developers who are not willing to learn something new and not adapt are the worst. Besides that, nobody is forced to learn Rust, only those who want to work on Rust parts.

Third, we do not need COBOL. All those systems that are still running on COBOL are businesses that shouldn’t exists in the first place anymore.
Like banks and insurance companies?
Correct, those institutions should not exist
Exactly.
So you advocate for the abolition of money also?
