One of the things I love about computing and computer science is how the wide variety of tools available, built over multiple generations, provide people with the leverage to bring their highly complex ideas to life. No matter how they work best, they can use those tools as a way to keep their mind focused on larger goals with broader context without yak shaving every hole punched in a punchcard.
You see a person whose conception of programming is different from yours; I see a person who's finding joy in the act of creating computer programs, and who will be able to bring even more of their ideas to life than they would have beforehand. That's something to celebrate, I think.

Calling aptitude "yak shaving" is certainly something to consider

This is the core part of what's changing - the most important people around me used to be "People who know how".
We're slowly shifting to "Knowing what you want" is beating the Know-how.
People without any know-how are able to experiment because they know what they want and can keep saying "No, that's not what I want" to a system which will listen to them for without complaining supplying the know-how.
From my perspective, my decades of accumulating know-how is entirely pointless and wiped away in the last 2 years.
Adapt or fall behind, there's no way to ignore AI and hope it passes by without a ripple.

I've found that if you're a novice coder you don't know what to ask for.
Your decades of experience are probably a bit like mine: you sense the cause of a problem in an almost psychic way, based on knowledge of the existing codebase, the person who wrote the last update, the "smell" of the problem. I've walked into a major incident, looked at a single alert on a dashboard, and almost with a smile on my face identified the root cause immediately. It's decades of knowledge that allow to know what to ask for.
Same with vibe coding: I've been having tremendous fun with it but occasionally a totally weird failure will occur, something that "couldn't happen" if you wrote it yourself. Like, you realise that the AI didn't refactor your code when you added the last feature, so it added "some tiny thing" to three separate functions. Then over several refactors it only updated one of those "tiny things", so now that specific feature only breaks in very specific cases.
Or let's say you want to get it to write something that AI seems to have problems with. Example, assemble and manage a NAS array using mdadm. I've been messing with that recently and Google Gemini has lost the whole array twice, and utterly failed to figure out how to rename an array device name. It's a hoot. Just to see if it would ever figure it out I kept going. Pages and pages of over-and-back, repeating the same mistakes, missing the obvious. Maybe it's been trained on 10 years of Muppets online giving terrible advice on how to manage mdadm?

As a counterexample, there's someone who vibe-coded a subscription adult website complete with payments and stuff, while having zero computer science experience while living in an RV. I can't find the link now, although last I saw on X, she was complaining about being blocked by trad finance after Bill Ackman's campaign.
So yeah, it's absolutely possible. From personal experience, I was able to implement a basic scan and go application complete with payment integrations without going through a single piece of documentation.
As long as you're ready to jostle for a bit in frustration with an AI, you can make something monetizable once you've identified an underserved market.

Gemini CLI is like a fresh self taught coder on massive amounts of cocaine and adderall.
Just last night I asked it to create a project plan as markdown files. It started writing to disk and I tabbed out to watch Squid Game
When I came back it was 80% through implementation and was trying to fix some weird python async issue in a loop over and over again. I never told it to implement anything. But it will always - ALWAYS - rush into implementation unless you tell it not to with ALL CAPS.
Google really needs to add a Claude style explicit plan mode for it…
I interrupted it, gave the error to Claude Code, which fixed it in one go.

And this is the reason for why I think I am productive with LLMs, and why people who know nothing about the underlying concepts are not going to be as productive.

I’ve had the … pleasure of working with outsourced talent for 20 years and I think it gives me an edge with LLMs
Both will never push back or say no and will just rush headlong into implementing - something. They will use 57 libraries when stdlib will do and make convoluted hierarchies when a simple functional program is enough.
But both can produce very good results if you have predetermined limits, acceptance criteria and a proper plan and spec.
Then you iterate in “sprints” and check the results after each one and challenge their output.

Yeah, in case of LLMs, I have never been told something is a bad idea, I had to point it out why it is a bad idea.
What you are talking about here is accidental vs essential complexity as described by Brooks in the 80s.
Your claim that LLMs do away entirely with accidental complexity and manage essential complexity for you is not supported by reality. Adding these tools to workflows adds a tonne of accidental complexity, and they still cannot shield you from all the essential complexity because they are often wrong.
There have been endless noise made over semantics but the plain fact is that LLMs render output that is incongruent with reality very often. And now we are trying to remedy it with what amounts to expert systems.
There is no silver bullet. You have to painstakingly get rid of accidental complexity and tackle essential complexity in order to build complex and useful systems.
I don't understand what's so abhorrent about it that people invent layers and layers of accidental complexity trying to avoid facing simple facts. We need to understand computers and domains with high accuracy to build any useful software and that's how it's always been and how it's always gonna be.
There is no silver bullet.

I find this very difficult to believe, but I have no idea what you do. I'm a generalist and this isn't even close to true for me with state of the art llms.

Nothing has served me better over the past few decades than accumulating ever more detailed and accurate knowledge of what it is exactly that computers do under the hood.
All the layers of abstraction are well intended and often useful. But they by no means eliminate the need to understand in detail the hard facts underlying computer engineering if you want to build performant and reliable software.
You can trade that off at different rates for different circumstances but the notion that you can do away entirely with the need to know these details has never been true.
More people being enabled to think less about these details necessitates more expertise to exist to support them, never less.

> All the layers of abstraction are well intended and often useful. But they by no means eliminate the need to understand in detail the hard facts underlying computer engineering if you want to build performant and reliable software.
Agreed. A good abstraction usually doesn't obviate the need for understanding what's going on behind the scenes, it just means that I don't have to think about it all the time.
As a more extreme example, I don't usually think about the fact that the Java (or Kotlin, Scala, ...) compiler generates bytecode that runs in an interpreter that translates the bytecode to machine code on the fly. But sometimes it's useful to remember (e.g. when dealing with instrumentation).
Another example are things like databases, or concurrency constructs, etc. There it's usually good to know the properties they guarantee and one way to be able to reason through these is by having some understanding of how they're implemented under the hood.

I agree at least a little bit, but let’s be honest: the history of software engineering is a history of higher and higher levels of abstraction wrapping the previously levels.
So part of this is just another abstraction. But another part, which I agree with, is that abstracting how you learn shit is not good. For me, I use AI in a way that helps me learn more and accomplish more. I deliberately don’t cede my thinking process away, and I deliberately try to add more polish and quality since it helps me do it in less time. I don’t feel like my know-how is useless — instead, I’m seeing how valuable it is to know shit when a junior teammate is opening PRs with critical mistakes because they don’t know any better (and aren’t trying to learn)

I like to read books on computers from the 70s and 80s. No trite analogies, just hard facts and diagrams. And explanations that start from scratch, requiring no previous knowledge - because there was none.
The thing about these layers of abstraction is that they add load and thus increase the demand for people and teams and organizations that command these lower levels. The idea that, on a systemic level, higher abstraction levels can diminish the importance, size, complexity or expertise needed overall or even keep it at current levels is entirely misguided.
As we add load on top, the base has to become stronger and becomes more important, not less.

This is a good point. However, the base is relatively narrow; there are many, many more people working in the popular frameworks and languages like e.g. React or Java or what have you than there are people who work on the fundamentals and have that low level understanding. And I'm afraid people at that level are going to become rare.
It's not hopeless though, it feels like that in the past decade, some of the smartest minds working at the lower levels of abstractions have come up with great new technologies. New programming languages that push the envelope of performance and security while maintaining good developer experience, great advancements in microchip technologies, that kinda thing.
It's important to maintain access to universities and higher education, where people who have the interest and mindset can learn and become part of this base that powers the greater software market.

I don't know. People working in web frameworks might be more visible, and more numerous than people working more low level stuff. But I don't think the latter is rarefied atmosphere at all. There are today several times more people working on those base levels than 10 or 20 years ago and I expect the trend to continue.
Sure, they will enable even more people proportionally to not think about those low level systems. But my argument is that the need for that low level expertise has always expanded and will keep expanding.
Automation entails tonnes of complexity that need to be managed. It doesn't just evaporate. More automatic systems will demand more people and teams to learn low level systems in great detail and at high levels of accuracy.

This is a sign that the user hasn't taken the time to set up their tools. You should be able to type log and have it tab complete because your editor should be aware of the context you're in. You don't need a fuzzy problem solver to solve non-fuzzy problems.
> user hasn't taken the time to set up their tools
The user, infact, has setup a tool for the task - an "AI model", unless you're saying one tool is better than others.

Then it's a real bad case of using the LLM hammer thinking everything is a nail. If you're truly using transformer inference to auto fill variables when your LSP could do that with orders of magnitude less power usage, 100% success rate (given it's parsed the source tree and knows exactly what variables exist, etc), I'd argue that that tool is better.
Of course LLMs can do a lot more than variable autocomplete. But all of the examples given are things that are removing cognitive overhead that probably won't exist after a little practice doing it yourself.

This. Set up your dev env and pay attention to details and get it right. Introducing probabilistic codegen before doing that is asking for trouble before you even really get started accruing tech debt.
You say "probabilistic" as if some kind of gotcha. The binary rigidness is merely an illusion that computers put up. At every layer, there's probabilistic events going on.
- Your hot path functions get optimized, probabilistically
- Your requests to a webserver are probabilistic, and most of the systems have retries built in.
- Heck, 1s and 0s operate in a range, with error bars built in. It isnt really 5V = 1 and 0V = 0.
Just because YOU dont deal with probabilistic events while programming in rust, or python doesnt mean it is inherently bad. Embrace it.

We’re comparing this to an LSP or intellisense type of system, how exactly are these probabilistic? Maybe they crash or get a memory leak every once in a while but that’s true of any software including an inference engine… I’m much more worried about the fact that I can’t guarantee that if I type in half of a variable name, that it’ll know exactly what i’m trying to type. It would be like preparing to delete a line in vim and it predicts you want to delete the next three. Even if you do 90% of the time, you have to verify its output. It’s nothing like a compiler, spurious network errors, etc (which still exist even with another layer of LLM on top).

Runtime events such as what you enumerate are unrelated to "probabilistic codegen" the GP references, as "codegen" is short for "code generation" and in this context identifies an implementation activity.

The scheduler that puts your program on a CPU works probabilistically. There are no rigid guarentees of workloads in Linux. Those only exist in real time operating systems.

Again, the post to which you originally replied was about code generation when authoring solution source code.
This has nothing to do with Linux, Linux process scheduling, RTOS[0], or any other runtime concern, be it operating system or otherwise.

Apples and oranges. It's frankly nonsense to tell me to "embrace it" as a phantom / strawman rebuttal about a broader concept I never said was inherently bad or even avoidable. I was talking much more specifically about non-deterministic code generation during implementation / authoring phase.

Old heads cling to their tools and yell at kids walking on lawns, completely unaware that the world already changed right under their noses.

We know the "world has changed": that's why we're yelling. The Luddites yelled when factories started churning out cheap fabric that'd barely last 10 years, turning what was once a purchase into a subscription. The villagers of Capel Celyn yelled when their homes were flooded to provide a reservoir for the Liverpool Corporation – a reservoir used for drinking water, in which human corpses lie.
This change is good for some people, but it isn't good for us – and I suspect the problems we're raising the alarm about also affect you.

Honestly, I've used a fully set up Neovim for the past few years, and I recently tried Zed and its "edit prediction," which predicts what you're going to modify next. I was surprised by how nice that felt — instead of remembering the correct keys to surround a word or line with quotes, I could just type either quotation mark, and the edit prediction would instantly suggest that I could press Tab to jump to the location for the other quote and add it. And not only for surrounding quotes, it worked with everything similar with the same keys and workflow.
Still prefer my neovim, but it really made me realize how much cognitive load all the keyboard shortcuts and other features add, even if they feel like muscle memory at this point.

I think you're clinging onto low-level thinking, whereas today you have tools at your disposal that allow you to easily focus on higher level details while eliminating the repetitive work required by, say, the shotgun surgery of adding individual log statements to a chain of function calls.
> Of course LLMs can do a lot more than variable autocomplete.
Yes, they can.
Managing log calls is just one of them. LLMs are a tool that you can use in many, many applications. And it's faster and more efficient than LSPs in accomplishing higher level tasks such as "add logs to this method/methods in this class/module". Why would anyone avoid using something that is just there?

I have seen people suggesting that it's OK that our codebase doesn't support deterministically auto-adding the import statement of a newly-referenced class "because AI can predict it".
I mean, sure, yes, it can. But drastically less efficiently, and with the possibility of errors. Where the problem can be easily soluble, why not pick the solution that's just...right?

Some tools are better than others at specific things. AI as is commonly understood today is better at fuzzy problems than many other tools. In the case of programming and being able to tab complete your way through symbols, you'll benefit greatly from having tools that can precisely parse the AST and understand schemas. There is no guess work when you can be exact. Using AI assistants for simple tab completion only opens the door for a class of mistakes we've been able to avoid for years.
In my experience consistency from your tools is really important, and AI models are worse at it than the more traditional solutions to the problem.
[deleted]
I don't want to wade into the debate here, but by "their tools" GP probably meant their existing tools (i.e. before adding a new tool), and by "a fuzzy problem solver" was referring to an "AI model".
I know old timers who think auto-completion is a sign of a lazy programmer. The wheel keeps turning....
Tab complete what? No LSP will complete context-appropriate message and parameters without writing any of it. "What did the user want to log here" is inherently a fuzzy problem.
And a chatbot can consistently work out what I want to log faster than I can?
Most of the time, yes. Since you refer to this as chatbot, I'm guessing you don't have much experience with things like cursor completion - give it a go before you're too negative.
Or the user works with user-hostile tools. Some stacks, cloud providers, etc are absolutely horrible to use.
There are many people out there that have absolutely no idea how horrible or great they have it.

The LLM is just Intellisense on literal steroids.
It can infer the correct logging setup from the rest of the project and add the most logical values to it automatically

You are commenting a blog post on how a user set up his tools. It's just that it's not your tool that is being showcased.

...or, hear me out, you don't have to. Think about it. If you have a tool that you type "add logs" and it's aware of best practices, context, and your own internal usage... I mean, why are you bothering with typing "log" at all?

To be perfectly fair saying ”it’s aware of the best practices, context and internal usage” is very misleading. It’s aware none of those (as it is not ”aware” of anything), and that is perfectly clear when it produces nonsensical results. Often the results are fine, but I see nonsensical results often enough in my more LLM dependant coworkers’ PRs.
I’m not saying not to use them, but you putting it like that is very dishonest and doesn’t represent the actual reality of it. It doesn’t serve anyone but the vendors to be a shill about LLMs.

I mean, "add logs" is twice as much work as "logs". I suspect you're implying a lot more, but you haven't really explained what you're referring to.
> Is that the part of programming that you enjoy? Remembering logger vs logging?
If you're proficient in a programming language then you don't need to remember these things, you just do it, much like spoken language.

This isn't a language thing, it's a project thing. Language things I can do fluently (like the example of a for loop in the OP comment... lol). But I work on so many different projects that it's impossible to keep this kind of dependency context fresh in my head. And I think that's fine? I'm more than happy to delegate that kind of stuff.
I find there is a limit to the number of programming languages I can stay actively proficient in at any given time.
I am using a much wider range of languages now that I have LLM assistance, because I am no longer incentivized to stick to a small number that are warm in my mental cache.

Really? At some point syntax became kind of a vague sense of color on top of the data flow, which is ultimately the same in any language. I don't even recall what it means to be proficient in one language versus another—surely most career programmers can ramp up on any given syntax or runtime in a relatively short period of time. The hard part is laying out the data flow.
Granted, AI can definitely ease that ramp-up time at the cost of lengthening it.

You still get to be proficient in an environment. I've got around 10 projects open in different Cursor windows. Logging in each of them is one or more of: logger.info, log.info, echo, eventLog.WriteEntry, console.log, syslog, printf, active_span&.set_tag, puts, rollbar.info, ... (and more)
It's not the ramp up time. There's no problem with learning yet another one. There's a problem with remembering them all as you switch between the projects. Most of the time LLM will know exactly what to use, how, and what data I want to log. Which will take way less time than me rediscovering how a specific project I haven't seen in weeks does things.

Yeah - a lot of these complaints feel like what I heard very early in my career about how you shouldn't learn python. The C learning I did was still useful, but I appreciate not artisanally crafting all my memory management by hand so that I can ship something that i've created faster
I definitely would never use Python in production. But it remains an amazing tool for prototyping and writing quick dirty scripts.
I can reasonably expect Python to be installed on every Linux system, the debugging experience is amazing (e.g. runtime evaluation of anything), there's a vast amount of libraries and bindings available, the amount of documentation is huge and it's probably the language LLMs know best.
If there were two languages I would suggest anyone to start with, it would be C and Python. One gives a comprehensive overview of low-level stuff, the other gives you actual power to do stuff. From there on you can get fancy and upgrade to more advanced languages.

Oh 100%, there's definitely an important trade-off, and it's important to know. But there was definitely a cultural disdain and judgment for "why are you using python to create a simple side project - C is superior".
It's still important to know both, and especially when I began working on aspects like multithreading I found my basis in C helped me learn far easier, but i'm definitely more supportive of the ship it mindset.
It's better to have a bad side project online than have none - you learn far more creating things then never making things, and if you need LLMs and Python to do that, fine!
I think it depends on how you approach these tools, personally I still quite focus on learning general, repeatable concepts from LLMs as i'm an idiot who needs different terms repeated 50 times in similar ways to understand them properly!

Programmers love to pretend their crap needs to handle FFANG loads to give them an excuse to overengineer :)
In many many cases Python will be perfectly fine until you hit absolutely massive loads, and even then you can optimise the hot path with something else while keeping the rest as is.

If you remove all the tiny details that you detest because you think you should better spend your time on the “important stuff”, be careful; you may wake up one day and not care enough about anything because you have been discarding stuff bit by bit.
It could happen! https://youtu.be/y1aSqZ23ydk
I like building stuff - I mean like construction, renovations. I like figuring out how I need to frame something, what order, what lengths and angles to cut. Obviously I like making something useful, but the mechanics are fun too.
I agree. This is like asking a carpenter "do you like sawing a plank of wood or do you like designing and creating a finished piece of work?" The answer is "both"—the low-level details may look tedious to those who don't have a true love for the work, but it's just a context switch to another deeply enjoyable aspect of the work as a whole.
> Is that the part of programming that you enjoy? Remembering logger vs logging?
No but genuinely like writing informative logs. I have been in production support roles and boy does the lack of good logging (or barely any logs at all!) suck. I prefer print style debugging and want my colleagues on the support side to have the same level of convenience.
Not to mention the advantages of being able to search through past logs for troubleshooting and analysis.

Enjoying any part of this seems a little odd to me. The enjoyable part is using the thing you built. Regardless, programming (remembering logger vs logging, syntax, debugging) is certainly the easier end of things.
It's not about focussing on what you love but about basic competence and being able to deal with simple programming problems

It's not unreasonable to briefly forget details like that, especially when you're dealing with a multi-language codebase where "how do I make a log statement?" requires a different pattern in each one.

You make my point for me.

I actually take pride in the logs I write because I write good ones with exactly the necessary context to efficiently isolate and solve problems. I derive a little bit of satisfaction from closing bugs faster than my colleagues who write poor logs.
Yeah, it’s also surprising because the user really shouldn’t be using f-strings for logging since they get interpolated whether or not the log level is set to INFO. This is more important when the user is writing say, debug logs that run inside hot loops, which will incur a significant performance penalty by converting lots of data to its string representation.
But sure, vibe away.
But sure, vibe away.
f""-strings for logging is an example of "practicality beats purity"
Yes, f""-strings may be evaluated unnecessarily (perhaps, t-strings could solve it). But in practice they are too convenient. Unless profiler says otherwise, it may be ok to use them in many circumstances.

Heh, I get to totally dunk on this guy by calling him a vibe coder for not using lazy evaled string interpolation.
Wait a second.. If I do ANY ACTUAL engineering and log out the time savings, it's completely negligible and just makes the code harder to read?
It is complete insanity to me that literally every piece of programming literature over the past sixty years has been drilling the concept about code readability over unncessary optimizations and yet still I constantly read completely backwards takes like this.

Having strong opinions on technical errata makes you sound smart and like you know what you're doing to the people who might want to hire you. Saying "I didn't bother to optimize this because it doesn't affect our bottom line" can be so easily reinterpreted as "I'm incompetent and never even thought about this angle in the first place". The OP has chosen an effective middle ground to communicate that they're serious about their work.
Yeah, so like I said, it’s not a problem, until it is. The gist of the article is that “LLMs let me add a lot of useful debugging messages to my logs”, that’s great, I use them for log messages too, but not with f-strings.
The footgun is there. Hot-loop debug logging can cost a ton with f-strings, and an LLM can just as easily use the standard log formatting without this problem. Few people use a profiler prior to a production bug (or just end up with eye popping autoscaling bills).
Shrug. I guess everyone can learn for themselves if it’s a problem for them. But I’ve been there; it would be nice if the tools did better with best practices.

Format strings are very useful, so I'd suggest fixing the language to let you use them. You don't have to live with it interpreting them too early!
Even better, you should be interpreting them at time of reading the log, not when writing it. Makes them a lot smaller.

This reminds me of a fun interaction in browser devtools: you can log a complex struct to the console. The browser does not copy the entire nested structure when you do so immediately, meaning that if someone mutates that struct after it was logged, the value you see depends on when you expanded the nested struct.

The thing is, the logging calls already accept variable arguments that do pretty much what people use f-string in logging calls for already, except better. People see f-string, they like f-string, and they end up in logs, that's really all there is to it.

Good news. You can get AI to refactor this sort of stuff away easily.
yep, putting user input into the message to be interpolated is asking for trouble
in C this leads to remote code execution (%n and friends)
in java (with log4j) this previously lead to remote code execution (despite being memory safe)
why am I not surprised the slop generator suggests it

One thing that has become abundantly clear from the AI craze is how many people - who do programming for a living - really don't like programming. I don't really understand why they got into the field; to be honest, it seems kind of like someone who doesn't like playing the guitar embarking on a career as a guitarist. But regardless of the reasons they seem to be pretty happy for a chance to not have to program any more.
Do you like 'solving problems' or do you like 'getting into the weeds'? Both are valid, and both are common uses of programming.
When I was younger, I loved 'getting into the weeds'. 'Oh, the audio broke? That gives me a great change to learn more about ALSA!'. Now that I'm older, I don't want to learn more about ALSA, I've seen enough. I'm now more in camp 'solving problems', I want the job done and the task successfully finished to a reasonable level of quality, I don't care which library or data structure was particularly used to get the job done. (both camps obviously overlap, many issues require getting into the weeds)
In this framework, the promise of AI is great for camp 'solving problems' (yes yes hallucinations etc.), but horrible for camp 'getting into the weeds'. From your framing you sound like you're from camp 'getting into the weeds', and that's fine too. But I can't say camp 'solving problems' doesn't like programming. Lot of carpenters out there who like to build things without caring what their hammer does.

To split the definitions one step further: That actually sounds not like you 'enjoy solving problems'(the process), but rather you 'enjoy not having the problem anymore'(the result).
Meaning you don't like programming for itself(anymore?), but merely see it as a useful tool. Implying that your life would be no less rich if you had a magical button that completely bypassed the activity.
I don't think someone who would stop doing it if given the chance can be said to "like programming", and certainly not in the way GP means.

AI is not "a magical button" though. It's another tool to solve the problem, that allows you to get a bit less into the weeds (sometimes, until it messes up), essentially by giving you a bunch of reasonable default behavior.
I spent a very long time getting into the weeds to learn everything about computer architecture, because at the time it seemed like it was the only way to do it and I wanted to have a career. In the meantime social media / cloud hosting / StackOverflow were invented, it became much easier for people to write online, and it turned out I didn't need to do any of that because the actual authors have all explained themselves on it.
Though, doing this is still the right way to learn how to debug things!
nb I actually just realized I never understood a specific bit of image processing math after working on ffmpeg for years, asked a random AI, and got a perfectly clear explanation of it.

I like solving problem. But I also want the problem to stay solved. And if I happen to see a common pattern between problems, then I build a solution generator.
Maybe because I don’t think in terms of code. I just have this mental image that is abstract, but is consistent. Code is just a tool to materialize it, just like words are a tool to tell a story. By the time I’m typing anything, I’m already fully aware of my goals. Designing and writing are two different activities.
Reading LLMs code is jarring because it changes the pattern midway. Like an author smashing the modern world and middle earth together. It’s like writing an urban fantasy and someone keeps interrupting you with some hard science-fiction ideas.

Exactly this. I still "get into the weeds" without AI if I really need to dig into learning something new or if I want to explore some totally new idea (LLMs don't really do "totally new"). If I'm debugging a CRUD app, though... eh, it's sunny outside and I only have a couple more hours of daylight, so, AI it is.
I love programming, but 90% of it is crappy toil due to language or tool design. I especially hate about 90% of the stuff one has to do to work around bad design decisions when writing significant amounts of python or javascript.
Disliking toil is not the same as disliking programming.

Most software developers work in software because it's well paid and much easier to break into than other similarly paid jobs.
Most software developers never write software outside of education or employment. That's completely normal.
Even most recreational programming is to solve a problem. Very few developers write software for the pleasure of it and would happily use a magical "solve my problem" button instead.
This is also true for all employers and customers.
Honestly, it sounds to me that you fundamentally misunderstand the industry in which you work.

Why would you work in a field that you have no interest in? Seems like a good way to get depressed
Most people work to support themselves and their families. Software's no different.
Pay and conditions in software are so much higher than any vocation that it attracts many people who would never program recreationally. If that's not you and you are overjoyed to be able to write software everyday, that's fine. But you should recognise that you're in a tiny minority of developers.

Do you like playing guitar or do you like putting pressure on the correct length of the string at the specific distance from the fret?
Do you like programming, or do you like manually typing out all the trivial details of each separate line? I've not found any pleasure in typing out the details of DTOs and their conversation functions repetitively by hand, for example.

One thing that has become abundantly clear from the AI craze is how many people who do programming for a living are actively hostile to fascinating new applications of computer science that open up entirely new capabilities and ways of working.
They are apparently also hostile to the people who just want to get things done. I may not love woodworking but I may still want to build my own damn boat.
I personally love programming but I don't disrespect people who are in it because they need to be or even just feel like they need to be.

Someone may say, like in this post, "AI makes my work easier", and that may be a valid point.
Someone else may say "AI has made my work much harder" [1], and that's a valid point too.
It may very well be that we'll find a place in the middle, but in the meantime it seem disingenuous to me to accept one side without acknowledging that the other is making valid points too.

Yes but cognitive load is a real thing. Being free to not think about the proper format to log some generic info about the state of the program might seem like a small thing, but remember, that frees up your mind to hold other concerns. See well-trodden research that the human mind can hold roughly three to five meaningful items in working memory at once. When in the flow of programming, you probably have a complicated unconscious process of kicking things out of working memory and re-acquiring them by looking at the code in front of you. I think the author is correctly observing that they are getting the benefit of not having to evict something from their mental cache to remember how logging works for this particular project (especially egregious if you work on 10 codebases and they each use a different logger).
How often do we print debug something that isn't just a single variable? I have defined a macro in my editor that expands into a nicely formatted logger call when I type "dbg" and the variable name. I can do it without thinking or losing focus.
On the other hand, if I used an LLM to guess what I wanted to get logged (as the author did), I'd have to read and verify the LLMs output. That's cognitive overhead I normally wouldn't have.
Maybe I'm missing something, but I just don't find myself in situations where I only vaguely know what I want to debug and would benefit from an LLM guessing what that could be.

Everyone's process if different, and by the way that applies to much simpler things, like peeling an apple. Ask 10 people to do something and they'll do it 10 different ways. And through the magic of availability heuristic, your comment was almost inevitable.
The author clearly dislikes writing logging code enough to put the work into creating a fine-tuned model for the purpose.
I thought “making tools to automate work” was one of the key uses of a computer but I might be wrong

I can totally write the logging code myself, but its tedious formatting the log messages "nicely". In my experience AI will write a nice log message and capture relevant variables automatically, unlike handwritten statements where I inevitably have to make a second pass to include a critical value I missed.
I think we need to abandon this idea of writing code like a scribe copying a book. There’s a plethora of tools ready to help you take advantage of the facts
- that the code itself is an interlinked structure (LSPs and code navigation),
- that the syntax is simple and repetitive (snippets and generators),
- that you are using a very limited set of symbols (grep, find and replace, contextual docs, completion)
- and that files are a tools for organization (emacs and vim buffers, split layout in other editors)
Your editor should be a canvas for your thinking, not an assembly line workspace where you only type code out.

What that statement is telling me is that the author at one point didn't consider logging to be a fully fledged formal non-functional requirement, more of an optional and/or informal side chore.
I used to work at a company that built software for mobile networks; their entire C codebase was full of logging statements, pretty much every step made in processing a signal was logged. Probably as a form of tracing, and automated instrumentation would possibly have been a better solution, but they were a bit old fashioned.

But, it looks like you are still caught up with iterating over arrays, so this realization might still be a few years away for you.

Yeah. This is a really weird complaint to be honest.
By that standard, python is not real programming because you're not managing your own memory. Is python considered AI now?

For me it's the opposite, I know exactly how to write log lines. It's just tedious. AI auto completes pretty much what I would have written.
If it's really that tedious and mechanical, there should be a code-level affordance for it (e.g. a macro, or something like https://github.com/lancewalton/treelog). Code is read more than it's written, and code that can be autocompleted isn't worth reading.
That's just a different type of automation. We can argue all day about determinism and repeatability, but at the end of tue day we are all in the business of automation. We are arguing about the specifics.

Why choose to use something unreliable instead of using or writing something reliable? Isn't reliability the whole point of automation in the first place?
And I think it's fairly widely accepted that you shouldn't check compiled binaries or generated code into your source control, you should check in the configuration that generates it and work with that. (Of course this presupposes that your generator is reliable)

I relate to this. The cognitive overhead of a for loop is, honestly, way less for me writing a log. There's something about writing logs that's a PITA.
Abstraction has always been a part of programming. Are you going to deride someone for not remembering how to write a sorting algorithm from scratch when .sort() is available? This is just another instance of that, trivial as it may be. The next abstraction level for programming is just natural language, if you want to try to gate keep that, have fun.
Natural language to formal language is not a matter of implementation details, it’s a matter of ambiguity where the definition of a term is contextual. Formalism is removing the dependency on context so that the semantic of a term or a proposition is embedded in itself.
Formalism is so essential that we we use it to create spontaneous form of programming language (that we call pseudocode) to express some idea clearly.

I like having muscles. I hate lifting weights.

Do you like doing anything? Sorry but it's just straight up bad if you only like results and hate the process to get there. That is not a fulfilling life
But this is using a machine to do the lifting for you so you don't develop the muscles. You are actually not strong through technology but left weak and helpless when left on your own.
It is just a bunch of people that don't take pride in self-sufficiency. It is a muscle that has atrophied for them.

We live in a society. That means giving up self-sufficiency in exchange for bigger leverage in our chosen specialisation. I am 110% confident that when electric power became widespread, people were making the exact same argument against using it as you are making now.

"I'm a chef, I hate cooking, I buy readymade meals in the supermarket."
You're right about the pride of writing actually good code. I think a lot about why I'm still writing software, and while I don't have an answer, it feels like the root cause is that LLMs deprive us of thoughts and decisions, our humanity actually.

You're right about the pride of writing actually good code. I think a lot about why I'm still writing software, and while I don't have an answer, it feels like the root cause is that LLMs deprive us of thoughts and decisions, our humanity actually.

Yes, exactly.
What you’re describing is useless noise that shouldn’t even be a blip on my radar.
Programming is solving a problem, not learning 20 different ways to say Log, logger, lumber, timber, and whatever else “creative” name writer of logger library chose to use.

Exactly, I switch between multiple languages, projects and library conventions daily.
I can’t be arsed to remember how I add parameters in which type and did this one have context or not.
Just today I got bit (again) by the fact that the Go log library doesn’t have Debug as an option. And I’ve been writing Go for a decade. (log/slog does have levels though)

came here to say this. I don't want to wrap my head around writing pretty logs and involving all the variables I want to eventually see in my logs. I just want to "dump it" and keep writing main logic
Also logging is important! Send structured logs if possible. Make sure structure is consistent between logs. You may have to reach for some abstraction or metaprogramming to do this.
All logs can be message, object and no need to format anything.
That said ai saves typing time.

The section you refer to is a justification for code completion and possible providing (visual) feedback for whether a various constructs are spelled or used correctly. It is fairly established that sort of thing increases programmer productivity (as in writing a Java program using notepad vs. writing it using IntelliJ).
In the old days, we used to do this by using static type inference. This is harder to do in dynamic languages (such as Python), so now we try to do it with LLMs.
It is not obvious to me that LLMs are a better solution; you may be able to do more but you loose the predictability of the classic approach.

You don't use auto-complete for for-loops? Wait... You use a compiled language, rather than writing machine code by hand? Some would call THAT programming.
> What you're describing is called: programming.
If you feel copying and pasting documentation is programming, you’re gonna have a really rough time.

Yeah! And actually writing this inefficient code in python? Seriously? Be a man, write assembly.
Python programmers, don't use f-strings for your logs.
# yes
logger.info("Super log %s", var)
# no
logger.info(f"Super log {var}")
Thanks for the reasons! I've been using f-strings because they're easy to keep track of, but you make really good arguments (I hadn't thought of Sentry/similar systems using %s to aggregate logs)
Well if you use loguru (and really you should, it is awesome) you would use, `logger.info("Super log {var}", var=var)` (possibly without the keys). It is also lazy and works better for structured logs.
The thing I like here is that it runs locally. I use Vim keyword completion[1] a lot for next-word completion. It does a broadly similar sort of "look at surrounding code to offer good suggestions" thing (no LLM stuff, of course). It's wrong often, but it's useful enough that it saves me time overall, I feel.
So, this sounds to me like an expanded version of that, more or less.
I think I'd prefer an AI future with lots of little focused models running locally like this rather than the "über models in the cloud" approach. Or at least having such options is nice.

There's also omni-completion, a bit more advanced: https://vim.fandom.com/wiki/Omni_completion

I get that writing logs can be incredibly frustrating, but most of the time people are looking at logs because either something went wrong, or they have a hunch that the program is misbehaving and they're looking for a clean sign or signal that they are on the right track.
If I've spent multiple hours on someones broken piece of code, the last thing I want to be thinking is "did some non-deterministic chat-bot write this?", "are these logs even internally consistent?", "Why does this log mention code that doesn't exist?".
I get that is most devs least favorite part, but logs and errors are supposed to be unshakable, ground-truth understandings, things that point you to the light in a dark room of broken spaghetti code and misunderstandings.
Think about this from a users or a testers perspective, can you imagine the compounding frustration you would experience? To be chasing a skein of understanding through wall of text that you only mostly understand, to find out that the hunch was based on a red-herring by a dev who wasn't bothered to help you in return.
Not to mention the amount of non-bugs you are generating for yourself in the future, we already have bug bounties being swarmed by LLM-gen faux-bugs, how is anyone supposed to reason about real bugs if the logs are only tangentially related to the truth?

This is the same complaint about all AI-generated code, the simple answer to which is, review the code yourself before committing. Or if it's a real project, it'll get reviewed by someone else anyway, same as any other code that could have a mistake in it.

Automates a tedious, time-consuming task. Easy to catch and correct failures. Love it. My only concern is (other than maybe verbosity) is of my log writing moments are opportunities to briefly reflect on what I have written, and maybe catch problems early.
Yeah, the areas AI has provided real value to me are the simple things: logging, docstrings and cli stuff being the best examples.
I can throw up a basic sketch, focusing on the code, and get it to add the quality stuff after.

I would have flagged that they're logging their Redis URL, if I was reviewing this. Most of the time this includes credentials.
Normally I think it's a bit rude to criticize the code of blog posts, bit I thought it was relevant here for these reasons:
"I often don’t even remove when I’m done debugging because they’re now valuable in prod" - think about where your production credentials end up. Most of the time, logging them won't hurt, just like keeping your password on a post-it doesn't hurt most of the time.
The arguments about letting an AI reduce the mental overhead is compelling, but this shows one of the (often mentioned) risks: you didn't write it so you didn't consider the implications.
Or maybe the author did consider it, and has a lot of good arguments for why logging it is perfectly safe. I often get pushback from other devs about stuff like this, for example:
- We're the only ones with access to the logs (still, no reason to store credentials in the logs)
- The Redis URL only has an IP, no credentials. (will we remember to update this log line when the settings.redis_url changes?)
- We only log warnings or higher in production (same argument as above)
Maybe I should stop worrying and learn to love AI? Human devs do the same thing, after all?

Usually, people use AI for reading logs, looking for interesting events or patterns. That goes way back. Microsoft was using it to classify and group similar crash dumps back in the 1990s.
Rust lets you write a default debug print for each struct, and will generate one if asked. So you don't have to write out all the fields yourself. That's enough to do the annoying part of the job.

AI and ML aren't new, they were already well established by the 90s. For example the book from which i first learned about neural networks[0] was written in 1997.

Classifiers go back that far.

Visual studio added the single line autocomplete thing a while back and it lasted about 2 days before i turned it off because it was frequently wrong and just got in the way. I often use the double tab template insert feature, but that would often accept the incorrect autocomplete instead, so i had to delete it and try again
Totally agree, this behaviour is maddening. I set a hotkey to toggle completions, made it useful again.
The use of AI for this seems somewhat overkill, one could just use a language and environment that is aware of whether `logger` or `logging` is available, and what variables are in scope. We have tools that allow us to treat programming as more than guessing the next character at random. Rather they allow you to offload tracking this context to the machine in a reliable way, typed languages and auto complete.
I do wonder if this is part of the divide in how useful one finds LLMs currently. If you're already using languages which can tell you what expressions are syntactically valid while you type rather than blowing up at runtime the idea a computer can take some of the cognitive overhead is less novel.

I think we are overcomplicating this a bit.
Typing "log" and tab to accept the auto complete is faster than writing the whole log yourself.
When you need to add a bunch of log statement, this tool makes the activity faster and less tedious.
Is it a technological breakthrough? No
Does it save hours of developer time each day? No
Is it nice to have? Hell yeah

Tab autocomplete in Cursor is surprisingly good at guessing what I want to log when I type slog.Info. I’m enjoying that time save.
I agree with K&R about debuggers: when writing services that you need to debug in prod, you live and die by your logs. That said, sometimes an interactive debugger is faster than adding logs, like when you’re not sure about the precise call stack that leads to a given point, or there’s a bunch of stuff you need to keep track of and adding logs for all of it is tedious. But pretty quickly you can hit a point where you’re wasting more time in the debugger than it would’ve taken to add those logs…

It does well but also sometimes gets it completely wrong but plausible looking. Together, we managed to make several quite intricate bugs. About two months in, I actually don't think my coding speed increased much from using Cursor - and I just can't take "Perfect, ..." "You're absolutley right, ..." - even with custom rules to supress it, it just can't help itself.
LLM-written code is typically over-commented and under-logged. So much so that I've given up pleading with them to stop commenting and start logging. Instead I say 'Great, now that you've written the code please replace the comments with logs.'
People, in their excitement to play with or write cool tools to automate boring details in the programming process, often underestimate the value of boring grunt work.
While what you're doing consciously is something simple you're simultaneously also mucking about in your codebase in the "spinal cord level", or spending quality time with your creation. It's times like those when bigger/other things often click together the first time all the while you're doing something that's seemingly just grunt work.

You should not use f-strings for logging, because that performs all the formatting _before_ the logging module determines if the log needs to be printed. You want the formatting overhead to happen only for logs that will get printed. You can’t achieve that with f-strings, just use normal logging calls.
It kinda speaks bad of the auto-completion that it suggests such anti-pattern.

You can do this with the new t strings! They’re like f strings, but a template instead. https://peps.python.org/pep-0750/
On the one hand writing logs can be tedious. Essentially logs are breadcrumbs signifying when significant state changes have logically taken place. From what I've seen, logs are added after every few lines and I always fantasized about creating a language where logging is "automatic".
On the other hand, writing logs is a skill worth mastering. Wrote too many and when a service crashes you have to shift through lots of noise and potentially miss the signal. I once went down a rabbit hole trying to root cause an issue in a Gunicorn application that had custom health check logic in it. An admin worker would read health check state from a file that worker threads wrote to. Sometimes a race condition would occur, in which an error log would be emitted. The thing was, this error wasn't fatal and was a red herring for why the service actually crashed. Of instead it would have been logged at the debug level a lot of time would have been saved.
Fine let LLMs write code but take logging seriously!!!

An aside, but it’s quite unfortunate that logger.info and logging.info are automatically linkified because of the .info TLD in this case. I don’t recommend clicking on those links.
I appreciate how the author highlighted the python domain-specific tricks like dropping imports and rewriting tabs/spaces. It's good to be reminded that even with "large" language models you can get better results with quality over quantity.
From how I read it dropping imports happens for every language.
Tangential, but making the logs understandable by the LLM is also very useful

I thought this was going to be about an AI which actually writes useful logs for your program. Eg if it crashes, it explains in normal language what happened.
Could full-line code completion and smarter log inference change how developers approach debugging and monitoring altogether? If so, how?
This is interesting, I like the way jetbrains is using the local models for auto completion.
Do you know if there's a similar solution for vscode?

I have a /addlogs claude command just for that. Logging is mostly boiler plate, I'm glad I can outsource it.

An example of the output would be very helpful
This tracks with how I've been doing my debug logs.
I ask the model to create tons of logs for a specific function and make sure there's an emoji in the beginning to make it unique (I know HN hates emojis).
Best thing of all, I can just say delete all logs with emojis and my patch is ready. Magical usage of LLMs

Does anyone else here dislike loguru on appearance? I don't have a well-articulated argument for why I don't like it, but it subconsciously feels like a tool that is not sharp enough.
Was looking for evidence, either way, honestly. The author is using loguru here and I've run into it for a number of production deployments.
Anyone have experiences to share?

It looks great out of the box, has fancy colors (if you want them).
It is easier to configure than logging and you don't need a lot go get_logger stuff. It does log rotation, and you has lazy formatted {} comments `logger.info("x={x:.2f}", x)`. It is better for threading/multiproc, handles exceptions better. And it is fast. I like it on appearance.
Never heard of it before this, but it looks nice. Some tools are better ergonomic than sharp?
AOP solved this 30 years ago, though.
Programmer apparently never learned about "import ... as" syntax, adopts fuzzy LLM autocomplete instead. News at 11
And look... I do get it. I have to switch between rust/typescript/python on the regular, and 3x sets of quirky syntax is a lot to keep in working memory.
I'd rather simplify our software stacks than accept that an autocomplete that lies to me is the only tractable solution, though

Loguru sucks very badly!
I would advise you not to use it. It is like trying to not do like everyone else, but still doing in a terribly wrong way ...
For example the backtrace try to be cooler for display but are awful, and totally not appropriate to pipe in monitoring systems like Sentry.
In the same way, as you can see in the article, that is the only logging library that doesn't accept the standard %-string syntax to use instead its own shitty syntax based on format.

The {} syntax is better, and more similar to f-strings. And you don't have to use that backtrace. I use it to send json for some batch jobs, or have it write to google cloud logger for gcp jobs. Are you holding it wrong?
It's totally subjective that it is better. It's not like it can "execute code" inline like f-string. Just the replacement character is the same, end of the comparison.
And any way the point is that more that it totally breaks the general convention for no valid reason. It's not even optional.
For gcp jobs you can just output the structured log in the standard output so I don't see the purpose here. There are other structured logging libraries if this is what you need.
For the backtrace yes, because logging.exception will be broken by default and all tools that process the backtrace automatically like sentry. And again, for no valid reason except than "look, my traceback looks so much cooler on my screen because I added crap and new lines when printing it"...

I don’t care too much about % vs {} . I have stuff where i need nice logs locally, and structured logs in batch, for me loguru made that easy. I don’t think it’s a terrible thing at all, but you do you :)

Not to be snarky, but when you become more experienced you will figure out that logging is just writing to permanent storage, one of the most basic blocks of programming, you don't need a dependency for that, writing to disk should be as natural as breathing air, you can do print("var",var). That's it.
If you are really anal you can force writing to a file with a print argument or just a posix open and write call. No magic, no remembering, no blogpost. Just done, and next.
