A good case study. I have found these two to be good categories of win:

> Use these tools as a massive force multiplier of your own skills.

Claude definitely makes me more productive in frameworks I know well, where I can scan and pattern-match quickly on the boilerplate parts.

> Use these tools for rapid onboarding onto new frameworks.

I’m also more productive here, this is an enabler to explore new areas, and is also a boon at big tech companies where there are just lots of tech stacks and frameworks in use.

I feel there is an interesting split forming in ability to gauge AI capabilities - it kinda requires you to be on top of a rapidly-changing firehose of techniques and frameworks. If you haven’t spent 100 hours with Claude Code / Claude 4.0 you likely don’t have an accurate picture of its capabilities.

“Enables non-coders to vibe code their way into trouble” might be the median scenario on X, but it’s not so relevant to what expert coders will experience if they put the time in.

This is a good takeaway. I use Claude Code as my main approach for making changes to a codebase, and I’ve been doing so every day for months. I have a solid system I follow through trial and error, and overall it’s been a massive boon to my productivity and willingness to attempt larger experiments.

One thing I love doing is developing a strong underlying data structure, schema, and internal API, then essentially having CC often one-shot a great UI for internal tools.

Being able to think at a higher level beyond grunt work and framework nuances is a game-changer for my career of 16 years.

This is more of a reflection of how our profession has not meaningfully advanced. OP talks about boilerplate. You talk about grunt work. We now have AI to do these things for us. But why do such things need to exist in the first place? Why hasn't there been a minimal-boilerplate language and framework and programming environment? Why haven't we collectively emphasized the creation of new tools to reduce boilerplate and grunt work?
abathologist · 11h ago
This is the glaring fallacy! We are turning to unreliable stochastic agents to churn out boilerplate and do toil that should just be abstracted or automated away by fully deterministic, reliably correct programs. This is, prima facie, a degenerative and wasteful way to develop software.

Saying boilerplate shouldn’t exist is like saying we shouldn’t need nails or screws if we just designed furniture to be cut perfectly as one piece from the tree. The response is “I mean, sure, that’d be great, not sure how you’ll actually accomplish that though”.

Saying boilerplate should exist is like saying every nail should have its own hammer.

Some amount of boilerplate probably needs to exist, but in general it would be better off minimized. For a decade or so there's sadly been a trend of deliberately increasing it.

Yes and its why AI fills me with impending doom: handing over the reigns to an AI that can deal with the bullshit for us means we will get stuck in a groundhog day scenario of waking up with the same shitty architecture for the foreseeable future. Automation is the opposite of plasticity.

I don’t think that will happen. It’s more like a 3d printer where you can feed in a new architecture and new design every day and it will create it. More flexibility instead of less.
Wowfunhappy · 1h ago
Isn’t trying to remove boilerplate how we end up with situations like left-pad?

I actually think I like the idea that, maybe by handling my boilerplate over to AI we can be more comfortable with having boilerplate to begin with.

When humans are in the loop everything pretty much becomes stochastic as well. What matters more is the error rate and result correctness. I think this shifts the focus towards test cases, measurement, and outcome.

No. This is a fundamentally erroneous analogy. We don't generate code by a stochastic process.

You don't? I do.

A few days ago I lost some data including recent code changes. Today I'm trying to recreate the same code changes - i.e. work I've just recently worked through - and for the life of me I can't get it to work the same way again. Even though "just" that is what I set out to do in the first place - no improvements, just to do the same thing over again.

Everything we do is a stochastic process. If you throw a dart 100 times at a target, it's not going to land at the same spot every time. There is a great deal of uncertainty and non-deterministic behavior in our everyday actions.
utyop22 · 3h ago
Go say this to a darts player who has hit a 9 darter…..

Actually no wait let’s expand it. Why not go say this to Ronnie O’Sullivan too!

The way you’re describing is such that there is no determinism behind what is being done. Simply not true.

jay-barronville · 1h ago
As much as it’s true that there’s stochasticity involved in just about everything that we do, I’m not sure that that’s equivalent to everything we do being a stochastic process. With your dart example, a very significant amount of the stochasticity involved in the determination of where the dart lands is external to the human thrower. An expert human thrower could easily make it appear deterministic.

I think that both of you are right to some extent.

It’s undeniable that humans exhibit stochastic traits, but we’re obviously not stochastic processes in the same sense as LLMs and the like. We have agency, error-correction, and learning mechanisms that make us far more reliable.

In practice, humans (especially experts) have an apparent determinism despite all of the randomness involved (both internally and externally) in many of our actions.

Reliably correct is good, but why does it need to be fully deterministic?

Reduced mental load. When it’s proven that a set of input will always result in the same output, you don’t have to verify the output. And you can just chain process together and not having to worry about time wasted because of deviations.

It feels like toil because it's not the interesting or engaging part of the work.

nothing prevents stochastic agents from producing reliable, deterministic and correct programs. it's literally what the agents are designed for. it's much less wasteful than me doing the same work and much much less wasteful trying to find a framework for all frameworks.

My take: money. Years ago, when I was cutting my teeth in software, efficiency was a real concern. Not just efficiency for limited CPU, memory, and storage. But also how you could maximize the output of smaller head count of developers. There was a lot of debate over which methodologies, languages, etc, gave the biggest bang for buck.

And then… that just kind of dropped out of the discussion. Throw things at the wall as fast as possible and see what stuck, deal with the consequences later. And to be fair, there were studies showing that choice of language didn’t actually make as big of difference as found in the emotions behind the debates. And then the web… committee designed over years and years, with the neve the ability to start over. And lots of money meant that we needed lots of manager roles too. And managers elevate their status by having more people. And more people means more opportunity for specializations. It all becomes an unabated positive feedback loop.

I love that it’s meant my salary has steadily climbed over the years, but I’ve actually secretly thought it would be nice if there was bit of a collapse in the field, just so we could get back to solid basics again. But… not if I have to take a big pay cut. :)

We have been emphasizing on creating abstractions since forever. We now have several different hardware platforms, programming languages, OS's, a gazillion web frameworks, tons of databases, build tools, clustering frameworks and on and on and on. We havn't done so entirely collectively, but I don't think the amount of choice here reflects that we are stupid, but that rather that "one size doesn't fit all". Think about the endless debates and flame wars about the "best" of those abstractions. I'm sure that Skynet will end that discussion and come up with the one true and only abstraction needed ;)
lukaslalinsky · 3h ago
I actually prefer the world with boilerplate connecting more important pieces of code together, over opinionated frameworks, because the boilerplate can evolve, charging the opinionated frameworks is much harder, and it's probably done by full rewrite. The thing is, the boilerplate needs to be kept to minimum, that's what I consider good API design. It allows you to do custom things, so you need some glue code, but not so much that you are writing a new framework each time you use it.
mikepurvis · 10h ago
I feel this some days, but honestly I’m not sure it’s the whole answer. Every piece of code has some purpose or expresses a decision point in a design, and when you “abstract” away those decisions, they don’t usually go away — often they’re just hidden in a library or base class, or become a matter of convention.

Python’s subprocess for example has a lot of args and that reflects the reality that creating processes is finicky and there a lot of subtly different ways to do it. Getting an llm to understand your use case and create a subprocess call for you is much more realistic than imagining some future version of subprocess where the options are just magically gone and it knows what to do or we’ve standardized on only one way to do it and one thing that happens with the pipes and one thing for the return code and all the rest of it.

Theres a million different million environments. This includes, OS, languages, frameworks and setups within those frameworks. Spring, java or kotlin, rest or grpc, mysql or postgres or, okhhtp or ktor, etc etc.

There is no software you could possibly write that works for everything thatd be as good as "Give me an internal dashboard with these features"

IanCal · 5h ago
Because the set of problems we make to be solvable with code is huge and the world is messy. Many of these things really are at a very high level of abstraction and the boiler plate feels boilerplatey but is actually slightly different in a way not automatable. Or it is but the configuration for that automation becomes the new bit you look at and see as grunt work.

Now we have a way we can get computers to do it!

Why haven't we collectively emphasized the creation of new tools to reduce boilerplate and grunt work?

You dont understand how things evolve.

There have been plenty of platforms that got rid of boilerplate - e.g. ruby on rails about 20 years ago

But once they become the mainstream, people can get a competitive edge by re-adding loads of complexity and boilerplate again. E.g. complex front end frameworks like react.

If you want your startup to look good you've got to use the latest trendy front end thingummy

Also to be fair, its not just fashion. Features that would have been advanced 20 years ago become taken for granted as time goes on, hence we are always working at the current limit of complexity (and thats why we're always overrun with bugs and always coming up with new platforms to solve all the problems and get rid of all thr boilerplate so that we can invent new boilerplate)

Haskell isn't immune to boilerplate. Luckily if you're stuck using Haskell there's a package to help you deal with it all: https://hackage.haskell.org/package/boilerplate
anyfoo · 10h ago
I find of all languages, Haskell often allows me to get by with the least boilerplate. Packages like lenses/optics (and yes, scrap your boilerplate/Generics) help. Funny package, though!
wyager · 9h ago
It's very minimal-boilerplate. It's done an exceptional job of eliminating procedural, tedious work, and it's done it in a way that doesn't even require macros! "Template Haskell" is Haskell's macro system and it's rarely used anymore.

These days, people mostly use things like GHC.Generics (generic programming for stuff like serialization that typically ends up being free performance-wise), newtypes and DerivingVia, the powerful and very generalized type system, and so on.

If you've ever run into a problem and thought "this seems tedious and repetitive", the probability that you could straightforwardly fix that is probably higher in Haskell than in any other language except maybe a Lisp.

I think this one way of looking at what your parent was describing.

They weren’t just saying ‘AI writes the boilerplate for me.’ They were saying: once you’ve written the same glue the 3rd, 4th, 5th time, you can start folding that pattern into your own custom dev tooling.

AI not as a boilerplate writer but as an assistant to build out personal scaffolding toolset quickly and organically. Or maybe you think that should be more systemized and less personal?

Html is rendered document. It’s ok to write it if you only need one document, but it’s better to use an actual template language or some generators if you’re going to have the same layout and components for many pages.

You’re asking to shift this job from the editor (you) to the viewer (the browser).

> Why hasn't there been a minimal-boilerplate language and framework and programming environment?

Haskell mostly solves boilerplate in a typed way and Lisp mostly solves it in an untyped way (I know, I know, roughly speaking).

To put it bluntly, there's an intellectual difficulty barrier associated with understanding problems well enough to systematize away boilerplate and use these languages effectively.

The difficulty gap between writing a ton of boilerplate in Java and completely eliminating that boilerplate in Haskell is roughly analogous to the difficulty gap between bolting on the wheels at a car factory and programming a robot to bolt on the wheels for you. (The GHC compiler devs might be the robot manufacturers in this analogy.) The latter is obviously harder, and despite the labor savings, sometimes the economics of hiring a guy to sit there bolting on wheels still works out.

Lisp can be very productive, but it requires actual design skills to wield it. It’s easier to teach python.

Yes. The author essentially asked Claude to port a driver from Linux 2.4 to Linux 6.8. Very certainly there must be sufficient amounts of training material, and web-searchable material, that describes such tasks. The author provided his own expertise where Claude could not find a good analogue in the training corpus, that is, the few actually non-trivial bits of porting.

"Use these tools as a massive force multiplier of your own skills" is a great way to formulate it. If your own skills in the area are near-zero, multiplying them by a large factor may still yield a near-zero result. (And negative productivity.)

For me is not so. It makes me way faster in languages that I don't know, but makes me slower on the ones I know because a lot of times, it creates code that will fail eventually.

Then I need to expend extra time following everything it did so I can "fix" the problem.

peteforde · 2h ago
My daily experience suggests that this happens primarily when the developer isn't as good as they assume that they are at expressing the ideas in their head into a structure that the LLM can run with. That's not intended to be a jab, just an opportunity for reflection.
skydhash · 1h ago
But the moment I got the idea in my head, is the moment I got the code for it. The time spent is moslty checking the library semantics, or if there’s not some function already written for a specific bit. There’s also checking if you’re not violating some contract somewhere.

A lot of people have the try and see if it works approach. That can be insanely wasteful in any moderately complex system. The scientist way is to have a model that reduce the system to a few parameters. Then you’ll see that a lot of libraries are mostly surface works and slighlty modified version of the same thing.

wer232essf · 1h ago
Totally agree these tools shine as amplifiers of existing skills. They take care of the boilerplate and let you focus on design and tricky logic, so productivity gains scale with expertise.

The onboarding angle is huge too: being able to “rent experience” in new frameworks drastically shortens ramp-up time, especially in environments with lots of stacks in play.

And you’re right about evaluation without real hours of use, it’s easy to underestimate what they can actually do. The “non-coders vibe coding” narrative misses that for experienced devs, they’re accelerants, not crutches.

ZYbCRq22HbJ2y7 · 11h ago
We have members on my team that definitely feel empowered to wade into new territory, but they make so much misdirected code with LLMs, even when we make everyone use Claude 4 thinking agents.

It seems to me that if you have been pattern matching the majority of your coding career, then you have a LLM agent pattern match on top of that, it results in a lot of headaches for people who haven't been doing that on a team.

I think LLM agents are supremely faster at pattern matching than humans, but are not as good at it in general.

baq · 6h ago
> they make so much misdirected code with LLMs

just points to the fact that they've no idea what they're doing and would produce different, pointless code by hand, though much slower. this is the paradigm shift - you need a much bigger sieve to filter out the many more orders of magnitude of crap that inexperienced operators of LLMs create.

It'll be interesting if tools like Claude will end up being used to highlight the people who have no clue what they are doing.
johnisgood · 1h ago
I think you can do this already. If you do not know the underlying concepts, or have no idea about how you have to architecture your project and so forth, then you will have problems with LLMs. So I think many if not most people who have problems with LLMs, it is most likely due to their lack of knowledge and/or their expectation that you can just simply write two sentences and it will figure out what you want and how you want it.

You cannot outsource thinking to LLMs, at least not yet, if ever. You have to be part of the whole process. You need to have knowledge. If you have no idea what it is doing or what you want it to do, you are going to have a difficult time.

skydhash · 52m ago
The thing is, is it slower to code with LLMs if you already have the knowledge? I think it is so. Coding is formal. There’s usually one correct way to tell the computer to do something (all the alternatives are equivalent through abstraction or transposition). The other ways are what we called bugs and there’s an infinty of them.

The programming language eliminates some (incorrect syntax) while the type system get rid of others (contract error). We also have linter that helps us with harmful patterns. But the range of errors is still enormous. So what’s the probability of having the LLMs be error free or as close as possible to the intended result?

We as humans have reduced the probability of error by having libraries of correct code (or outsourcing the correction of code), thus having a firmer and cognitively manageable foundation to create new code. As well as not having to rely on language to solve problems.

matwood · 26m ago
> The thing is, is it slower to code with LLMs if you already have the knowledge?

Maybe if all you do is code, but that’s not how most people work. Being able write I need these things done in this way and then attend a meeting or start researching the next thing is valuable. And because of my other obligations there’s no way I could do more without Claude.

One of the things I’ve noticed is that those people are the same people who before would spend 3 weeks on something before coming out with a copy of the docs that doesn’t actually solve the problem at hand, but it spits out a result that almost matches what you asked for. They never understood the problem in the first place, they always just hammered until the nail went in - now they just have a different tool.
skydhash · 48m ago
Everytime I have to mentor juniors, it’s more productive to get them to articulate the problem and their initial solution. It’s often sufficient to highlight (mostly for them) how little they actually know about the problem itself to actually rush to solve it.

Also new languages - our team uses Ruby, and Ruby is easy to read, so I can skip learning the syntax and get the LLM to write the code.

If Ruby is "easy to read" and assuming you know a similar programming language (such as Perl or Python), how difficult is it to learn Ruby and be able to write the code yourself?

> ... but I don't need to learn Ruby to write acceptable-level code [0].

Since the team you work with uses Ruby, why do you not need to learn it?

> [0] acceptable-level as defined by the rest of the team - they're checking my PRs.

Ah. Now I get it.

Instead of learning the lingua franca and being able to verify your own work, "the rest of the team" has to make sure your PR's will not obviously fail.

Here's a thought - has it crossed your mind that team members needing to determine if your PR's are acceptable is "a bad thing", in that it may indicate a lack of trust of the changes you have been introducing?

Furthermore, does this situation qualify as "immediately productive" for the team or only yourself?

EDIT:

If you are not a software engineer by trade and instead a stakeholder wanting to formally specify desired system changes to the engineering team, an approach to consider is authoring RSpec[0] specs to define feature/integration specifications instead of PR's.

This would enable you to codify functional requirements such that their satisfaction is provable, assist the engineering team's understanding of what must be done in the context of existing behavior, identify conflicting system requirements (if any) before engineering effort is expended, provide a suite of functional regression tests, and serve as executable documentation for team members.

I lead the engineering team at my org and we hire almost exclusively for c++ engineers (we make games). Our build system by happenstance is written in c#, as are all the automation scripts. Out of our control to change. Should we require every engineer to be competent and write fluent c# or should we let them just get on with their value adds?

skydhash · 40m ago
Programming language are not actually that different. There’s only a few models of computation and paradigms. The effort is mostly about learning the syntax, the standard library and whatever abstractions built around the above paradigms and computation models. And learning the standard library is the tough one.

I would expect every engineer to be able to read C#. It’s not that hard.

No, not at all.

What I was speaking about was if the person to whom I replied is not a s/w engineer, then perhaps a better contribution to their project would be to define requirements in the form of RSpec specifications (since Ruby is in use) and allow the engineering team to satisfy them as they determine appropriate.

I have seen product/project managers attempt to "contribute" to a development effort much like what was described. Usually there is a power dynamic such that engineers cannot overtly tell the manager(s), "you define the 'what' and we will define the 'how'." Instead, something like the PR flow described is grudgingly accepted and then worked around.

Code reviews (especially internal ones) generally assume that the person writing the original code has an idea of what they are doing and are designed to catch mistakes that humans might make. Just because they probably work to improve codebases with human submissions doesn't mean that they are good enough filter for LLM-generated code that the submitter doesn't sufficiently understand and has submitted without their own review. Same goes for CI and testing.

This reminds of some of the comments made by reviewers during the infamous Schön scientific fraud case. The scientific review process is designed to catch mistakes and honest flaws in research. It is not designed to catch fraud, and the evidence shows that it is bad at it.

Another applicable example would be the bad patches fiasco with the Linux kernel. (And there is going to be a session at the upcoming maintainers' summit about LLM-generated kernel patches.)

> Use these tools as a massive force multiplier of your own skills.

I've felt this learning just this week - it's taken me having to create a small project with 10 clear repetitions, messily made from AI input. But then the magic is making 'consolidation' tasks where you can just guide it into unifying markup, styles/JS, whatever you may have on your hands.

I think it was less obvious to me in my day job because in a startup with a lack of strong coding conventions, it's harder to apply these pattern-matching requests since there are fewer patterns. I can imagine in a strict, mature codebase this would be way more effective.

rmoriz · 10h ago
In times of Rust and Typescript (just examples) coding standards are explicit. It‘s not optional anymore. All my vibe coding projects are using CI with tests including style and type checks. The agent makes mistakes but it sees the failing tests and fixes it. If you vibe code like we did Perl and PHP in 1999 you‘re gonna have a bad time.
baq · 6h ago
In a startup, especially early, the only thing that isn't optional is shipping. You can fix any and all issues later, first you have to ensure there is a 'later'. (That's not to say you shouldn't do it at all, but definitely focus on the business before the tech.)

I had an Amiga disk image (*.adf) that I wanted to extract the files from. There are probably tools to do this but I was just starting with Claude Code, so I asked it to write a tool to extract the files by implementing the filesystem.

It took a few prompts but I know enough about FFS (the Amiga filesystem) to guide it, and it created exactly the tool I wanted.

"force multiplier of your own skills" is a great description.

I think this is illustrative of the kind of productive things you can do with an LLM if you know what you are doing. Is it perfect, no. Can they do useful things if you prompt correctly, absolutely. It helps knowing what you are doing and having enough skill to make good judgment calls yourself.

There are currently multiple posts per day on HN that escalate into debates on LLMs being useful or not. I think this is a clear example that it can be. And results count. Porting and modernizing some ancient driver is not that easy. There's all sorts of stuff that gets dropped from the kernel because it's just too old to bother maintaining it and when nobody does, deleting code becomes the only option. This is a good example. I imagine, there are enough crusty corners in the kernel that could benefit from a similar treatment.

I've had similar mixed results with agentic coding sometimes impressing me and other times disappointing me. But if you can adapt to some of these limitations it's alright. And this seems to be a bit of a moving goalpost thing as well. Things that were hard a few months ago are now more doable.

The more you use the tools, the more you're able to recognize the situations in which they're useful.

These studies keep popping up where they randomly decide whether someone will use AI to assist in a feature or not and it's hard for me to explain just how stupid that is. And how it's a fundamental misunderstanding of when and how you'd want to use these tools.

It's like being a person who hangs up drywall with screws and your boss going "Hey, I'm gonna flip a coin and if it's heads you'll have to use the hammer instead of a screwdriver" and that being the method in which the hammer is judged.

I don't wake and go "I'm going to use AI today". I don't use it to create entire features. I use it like a dumb assistant.

I actually do this now. That's one of those things that went from impossible to doable under some circumstances. Still a bit of a coin flip but it can work well in some code bases. I still have a mental block even asking for these things under the assumption it would not work anyway. But I've been pleasantly surprised a few times where this actually works.

I've used Claude Code in the past month to do development on CoMaps [1] using the 20 USD/month plan.

I've been able to do things that I would not have the competence for otherwise, as I do not have a formal software engineering background and my main expertise is writing python data processing scripts.

E.g., yesterday I fixed a bug [2] by having Claude compare the CarPlay and iOS search implementations. It did at first suggest another code change than the one that fixed it, but that felt just like a normal part of debugging (you may need to try different things)

Most of my contributions [3] have been enabled by Claude, and it's also been critical to identify where the code for certain things are located - it's a very powerful search in the code base

And it is just amazing if you need to write a simple python script to do something, e.g., in [4]

Now this would obviously not be possible if everyone used AI tools and no one knew the existing code base, so the future for real engineers and architects is bright!

> using these tools as a massive force multiplier…

Even before tools like CC it was the case that LLMs enabled venturing into projects/areas that would be intimidating otherwise. But Claude-Code (and codex-cli as of late) has made this massively more true.

For example I recently used CC to do a significant upgrade of the Langroid LLM-Agent framework from Pydantic V1 to V2, something I would not have dared to attempt before CC:

https://github.com/langroid/langroid/releases/tag/0.59.0

I also created nice collapsible html logs [2] for agent interactions and tool-calls, inspired by @badlogic/Zechner’s Claude-trace [3] (which incidentally is a fantastic tool!).

[2] https://github.com/langroid/langroid/releases/tag/0.57.0

[3] https://github.com/badlogic/lemmy/tree/main/apps/claude-trac...

And added a DSL to specify agentic task termination conditions based on event-sequence patterns:

https://langroid.github.io/langroid/notes/task-termination/

Needless to say, the docs are also made with significant CC assistance.

LLMs are also good for writing quick experiments and benchmarks to satisfy someone's curiosity. For example, once I was wondering, how much time does it take to migrate a cache line between cores when several processes access the same variable - and after I wrote a detailed benchmark algorithm, LLM generated the code instantly. Note that I described the algorithm completely and what it did is just translated it into the code. Obviously I could write the code myself, but I might need to lookup a function (how does one measure elapsed time?), I might make mistakes in C, etc. Another time a made a benchmark to compare linear vs tree search for finding a value in a small array.

It's very useful when you get the answer in several minutes rather than half a hour.

codedokode · 4h ago
Also I wanted to add that LLMs (at least free ones) are pretty dumb sometimes and do not notice obvious thing. For example, when writing tests they generate lot of duplicated code and do not move it into a helper function, or do not combine tests using parametrization. I have to do it manually every time.

Maybe it is because they generate the code in one pass and cannot return back and fix the issues. LLM makers, you should allow LLMs to review and edit the generated code.

Blast from the past! When I was a kid we had such a floppy tape device connected to a 386 or 486 computer my parents had. I think it was a Colorado Jumbo 250. I think the actual capacity was 125MB, but the drive or the backup software had some built-in compression, hence why it was marketed as a 250MB drive. Never tried to use it with the Linux ftape driver, though.

It wouldn't surprise me if the drive and the tapes are still somewhere in my parents storage. Could be a fun weekend project to try it out, though I'm not sure I have any computer with a floppy interface anymore. And I don't think there's anything particularly interesting on those tapes either.

In any case, cool project! Kudos to the author!

If you don't have the technical understanding of a language or framework, there is going to be a lot of ambiguity in your prompts.

This specificity gap leads the LLM to fill in those gaps for you, which may not be what you intended. And that's usually where bugs hide.

I think this is the flip side to being a "force multiplier"

Hm. That was interesting, so I ran it as prompt to Qwen3-Coder (which I run locally). It spat out a bunch of C functions together with a C struct and commented:

  This implementation provides:
  Generic Tuple Structure: A flexible tuple that can hold different types of elements (int, double, string, float)
  Constructor Function: tuple_create() initializes a new tuple with specified size
  Type-Safe Setters:
    tuple_set_int(), tuple_set_double(), tuple_set_string(), tuple_set_float()
  Type-Safe Getters:
    tuple_get_int(), tuple_get_double(), tuple_get_string(), tuple_get_float()
  Memory Management: Automatic memory allocation and deallocation
  Utility Functions:
   tuple_print() for displaying tuple contents
   tuple_destroy() for cleanup
Seems to be a common enough request to be present in the model's training data :D Even the code looked fine, apart from being a very naive and thus slow implementation.

LLM assisted coding can get you from an idea to MVP in an evening (within maybe 1 or 2 Claude 5 hour quota windows).

Within a few prompts I've got something workable and I can determine if it was a good idea or not.

This, for me, is the actual gain and I don't see a lot of people talking about it: it's not that I finish a project faster the LLMs. From what I've read and personally experienced, it probably takes about as long to complete a project with or without the LLMs. But the difference is, without it I spend all that time deeply engaged, unable to do anything else. With the LLMs I no longer require continuous focus. It may be the same wall-clock time but my own mental capacity is not being used at or near capacity.

It's never about lack of work but lack of people who have the prerequisite expertise to do it. If you don't have experience w/ kernel development then no amount of prompting will get you the type of results that the author was able to achieve. More specifically, in theory it should be possible to take all the old drivers & "modernize" them to carry them forward into each new version of the kernel but the problem is that none of the LLMs are capable of doing this work w/o human supervision & the number of people who can actually supervise the LLMs is very small compared to the amount of unmaintained drivers that could be ported into newer kernels.

There is a good discussion/interview¹ between Alan Kay & Joe Armstrong about how most code is developed backwards b/c none of the code has a formal specification that can be "compiled" into different targets. If there was a specification other than the old driver code then the process of porting over the driver would be a matter of recompiling the specification for a new kernel target. In absence of such specification you have to substitute human expertise to make sure the invariants in the old code are maintained in the new one b/c the LLMs has no understanding of any of it other than pattern matching to other drivers w/ similar code.

There is usually a specification for how hardware works. But:

1. The original hardware spec is usually proprietary, and

2. The spec is often what the hardware was supposed to do. But hardware prototype revisions are expensive. So at some point, the company accepts a bunch of hardware bugs, patches around them in software, ships the hardware, and reassigns the teams to a newer product. The hardware documentation won't always be updated.

This is obviously an awful process, but I've seen and heard of versions of it for over 20 years. The underlying factors driving this can be fixed, if you really want to, but it will make your product totally uncompetitive.

AI doesn’t need to replace a specialist in their entirety for it to tank demand for a skill. If the people that currently do the work are significantly more productive, fewer people will be necessary to the same amount of work. Then, people trying to escape obsolescence in different, more popular specialties move into the niche ones. You could easily pass the threshold of having less work than people without having replaced a single specialist.

Off-topic, but I wish Linux had a stable ABI for loadable kernel modules. Obviously the kernel would have to provide shims for internal changes because internal ABI constantly evolves, so it would be costly and the drivers would probably run slower over time. Yet, having the ability to use a driver from 15 years ago can be a huge win at times. That kind of compatibility is one of the things I love about Windows.

Something not yet mentioned by other commenters is the "giant caveat":

  As a giant caveat, I should note that I have a small bit of 
  prior experience working with kernel modules, and a good 
  amount of experience with C in general, so I don’t want to 
  overstate Claude’s success in this scenario. As in, it 
  wasn’t literally three prompts to get Claude to poop out a 
  working kernel module, but rather several back-and-forth 
  conversations and, yes, several manual fixups of the code. 
  It would absolutely not be possible to perform this 
  modernization without a baseline knowledge of the internals 
  of a kernel module.
Of note is the last sentence:

  It would absolutely not be possible to perform this 
  modernization without a baseline knowledge of the internals 
  of a kernel module.
This is critical context when using a code generation tool, no matter which one chosen.

Then the author states in the next section:

  Interacting with Claude Code felt like an actual 
  collaboration with a fellow engineer. People like to 
  compare it to working with a “junior” engineer, and I think 
  that’s broadly accurate: it will do whatever you tell it to 
  do, it’s eager to please, it’s overconfident, it’s quick to 
  apologize and praise you for being “absolutely right” when 
  you point out a mistake it made, and so on.
I don't know what "fellow engineers" the author is accustomed to collaborating with, junior or otherwise, but the attributes enumerated above are those of a sycophant and not any engineer I have worked with.

Finally, the author asserts:

  I’m sure that if I really wanted to, I could have done this 
  modernization effort on my own. But that would have 
  required me to learn kernel development as it was done 25 
  years ago.
This could also be described as "understanding the legacy solution and what needs to be done" when the expressed goal identified in the article title is:

  ... modernize a 25-year-old kernel driver

  ... required me to learn ...

I read "junior" as 'subordinate' and 'lacking in discernment'.. -- Sycophancy is a good description. I also like "bullshit" (as in 'for the purpose of convincing'). https://en.wikipedia.org/wiki/Bullshit#In_the_philosophy_of_...

The point being, there's nuance to "it felt like a collaboration with another developer (some caveats apply)". -- It's not a straightforward hype of "LLM is perfect for everything", nor is it so simple as "LLM has imperfections, it's not worth using".

> Another key activity identified as a benefit to avoid in the above quote is: > > ... required me to learn ...

It would be bad to avoid learning fundamentals, or things which will be useful later.

But, it's not bad to say "there are things I didn't need to know to solve a problem".

Again, this is not the same as implementing an OS device driver. Even though one could justify saying Firefox is way more complicated than a Linux device driver (and I would agree), the fact is that a defective device driver can lock-up the machine[0], corrupt internal data structures resulting in arbitrary data corruption, and/or cause damage to peripheral devices.

Apparently it's not, though. The author here had some baseline knowledge of how Linux kernel modules work, but the impression I got is that they would not have been able to do this on their own without a lot of learning.

> the fact is that a defective device driver can lock-up the machine[0], corrupt internal data structures resulting in arbitrary data corruption, and/or cause damage to peripheral devices.

Now that's some gatekeeping right there. "Only experts can write kernel modules" is a pretty toxic attitude to have.

Anyone can write kernel module.

On their computers.

Not mine.

"...kernel development as it was done 25 years ago."

Not "...kernel development as it is done today".

That "25 years ago" is important and one might be interested in the latter but not in the former.

To be fair, a "baseline knowledge of the internals of a kernel module" is not that difficult to acquire.

I think a moderately-skilled developer with experience in C could have done this, with Claude's help, even if they had little or no experience with the Linux kernel. It would probably take longer to do, and debugging would be harder, but it would still be doable.

Upgrades and “collateral evolution” are very strong use cases for Claude.

I think the training data is especially good, and ideally no logic needs to change.

I hope Dmitry did a good job. I've got a box of 2120 tapes with old backups from > 20 years ago, and I'm in the process of resurrecting the old (486) computer with both of my tape drives (floppy T-1000 and SCSI DDS-4). It would be nice to run a modern kernel on it.

There is literally a GitHub repository, six years old, that ports an out-of-tree ftape driver to modern Linux:

https://github.com/Godzil/ftape

Could it be that Misanthropic has trained on that one?

Ouch. The part where it says it’s not possible to use a normal floppy and the tape flip anymore seemed odd enough, but those last points should scare anyone away from trying these on anything important.

bgwalter · 1h ago
Yes, Godzil's repo could have the issues you point out but still give hints to Claude what APIs to replace. Or the latest possibly-Claude-plagiarized version perhaps has the same issues.

Qudos to the author.

I keep beating on the drum that they correctly point out. It's not perfect. But it saves hours and hours of work in generating compared to small conceptual debugging.

The era of _needing_ teams of people to spit out boilerplate is coming to an end. I'm not saying doing learn to write it, learning demands doing, making mistakes and personal growth. But after you've mastered this there's no need to waste time writing booklet plate on the clock unless you truly enjoy it.

This is a perfect example of time taken to debug small mistakes << time to start from scratch as a human.

Time, equivalent money, energy saved all a testament to what is possible with huge context windows and generic modern LLMs :) :) :)

I don't think we really need an article a day fawning over LLMs. This is what they do. Yep.

Only thing I got from this is nostalgia from the old PC with its internals sprawled out everywhere. I still use desktop PCs as much as I can. My main rig is almost ten years old and it's been upgraded countless times although is now essentially "maxed out". Thank god for PC gamers, otherwise I'm not sure we'd still have PCs at all.

Is Claude code better than ChatGPT?
prameshbajra · 4h ago
I have been testing both Claude code and Codex CLI for the past few weeks and I found codex output to be better than claude.

I like how Claude code is more advanced in terms of CLI functionality but I prefer Codex output (with model high)

If you do not want to pay for both, then you can pick anyone and go with it. I don't think the difference is huge.

In my experiments claude4 opus generated by far the best code (for my taste and purposes) but it's also a pretty expensive model. I think I used up $40 in one evening of frantic vibe-coding.

AI works better when it has an example. In this case, all the code needed for the driver to work was already there as the example. It just had to update the code to reflect modern kernel development practices.

The same approach can be used to modernise other legacy codebases.

I'm thinking of doing this with a 15 year old PHP repo, bringing it up to date with Modern PHP (which is actually good).

Neat stuff. I just got Claude code and am training myself on Rails, I'm excited to have assistance working through some ideas I have and seeing it handle this kind of iterative testing is great.

One note: I think the author could have modified sudoers file to allow loading and unloading the module* without password prompt.

nico · 12h ago
Claude is really good with frameworks like Rails. Both because it’s probably seen a lot of code in its training set, and because it works way better when there is a very well defined structure
anyfoo · 12h ago
... which would allow you to load arbitrary code into the kernel, pretty much bypassing any and all security. You might as well not have a password at all. Which, incidentally, can be a valid strategy for isolated external dev boards, or QEMU VMs. But on a machine with stuff you care about? You're basically ripping it open.
unethical_ban · 12h ago
He was already loading "arbitrary" Claude code, no? I'm suggesting there was a way to skip password entry by narrowly tailoring an exception.

Another thought, IIRC in the plugins for Claude code in my IDE, you can "authorize" actions and have manual intervention without having to leave the tool.

My point is there were ways I think they could have avoided copy/paste.

anyfoo · 12h ago
While I personally would have used a dedicated development target, the workflow he had at least allowed him to have a good look at any and all code changes, before approving with the root password.

That is a bit different than allowing unconfirmed loading of arbitrary kernel code without proper authentication.

frumplestlatz · 11h ago
> One note: I think the author could have modified sudoers file to allow loading and unloading the module* without password prompt.

Even a minor typo in kernel code can cause a panic; that’s not a reasonable level of power to hand directly to Claude Code unless you’re targeting a separate development system where you can afford repeated crashes.

mschuster91 · 5h ago
the problem here is that Apple, while at least not standing actively in the way (like console manufacturers), provides zero documentation on how stuff works internally. You gotta reverse-engineer everything, and that either takes at least a dozen highly qualified and thus rare and expensive-to-hire people or someone hard on the autism-hyperfixation spectrum with lots of free time to spare and/or the ability to turn it into an academic project. AI can't help at all here because even if it were able to decompile Apple's driver code, it would not be able to draft a coherent mental model on how things work.

M3, to answer the second part why AI won't be of much help, onwards use a massively different GPU architecture that needs to be worked out, again, from scratch. And all of that while there is a substantial number of subsystems remaining on M1, M2 and its variants that aren't supported at all, only partially supported or with serious workarounds, or where the code quality needs massive work to get upstreamed into Linux.

And on top of that, a number of contributors burned out along the way, some from dealing with the ultra-neckbeard faction amongst Linux kernel developers, some from other mental health issues, and Alyssa departed for Intel recently.

No tests whatsoever. This isn't getting close to being merged into mainline and it will stay out-of-tree for a long time.

That's even before taking on the brutal linux kernel mailing lists for code review explaining what that C code does which could be riddled with bugs that Claude generated.

No thanks and no deal.

"The intention is to compile this driver as an out-of-tree kernel module, without needing to copy it into the kernel source tree. That's why there's just a simple Makefile, and no other affordances for kernel inclusion. I can't really imagine any further need to build this driver into the kernel itself.

The last version of the driver that was included in the kernel, right up until it was removed, was version 3.04.

BUT, the author continued to develop the driver independently of kernel releases. In fact, the last known version of the driver was 4.04a, in 2000.

My goal is to continue maintaining this driver for modern kernel versions, 25 years after the last official release." - https://github.com/dbrant/ftape

Looks like that hasn't been updated in 6 years, and only supports the 2.6.x kernel.

I doubt it would have been significantly easier to start the porting effort from that vs. the original 2.4.x source.

> No tests whatsoever.

Test coverage between subsystems in the Linux kernel varies widely. I don't think a lack of tests would prevent inclusion.

> No thanks and no deal.

I mean, now we have a driver for this old hardware that runs on a modern kernel, which we didn't before. I imagine you don't even have that hardware, so why do you care if someone else gets some use out of it?

The negativity here in many of these comments is just staggering. I've only recently started adopting LLM coding tools, and I still remain a skeptic about the whole thing overall, but... damn. Seems like most people aren't thinking critically and are just regurgitating "durrrr LLMs bad" over and over.

cmpxchg8b · 26m ago
Yes, the negativity is infuriating. This is the mindset that is going to get left behind. I'm no LLM maximalist but they clearly have their uses in the right context and the right hands.
