hash0··on Ask HN: Is there a marketable "skill" to using AI?
There is. Companies are anxious to be left behind and want to hire people who are confident in working with AI. And trust me, especially in ageing societies, even your colleagues who are demonstrably tech savvy are not necessarily inclined to working with AI, so you definitely have an advantage there.
hash0··on Ask HN: How do you learn with LLMs?
I generally outline the problem first that I would like to solve, then ask for best practice approaches and industry standards that apply to situations. Next, I ask to summarize the pros and cons of the various possible solutions and how they apply to my particular situation.
hash0··on SETI@Home was the coolest thing
Isn't there something similar available today, but with protein folding?
hash0··on Ask HN: Can we direct AI on our personal projects during work hours?
Honest question from an enthusiastic AI user:

"using AI consists of sending a message a waiting a long time (often an hour or more) before the AI finishes a task."

>>> What on earth are you prompting AI with that it takes so long to finish?!

hash0··on Why remote roles are region specific and not 100% remote?
Time Zones factor into that. They want to be able to operate 24/7 "follow the sun"-style, so they want to get people half way around the globe - who obviously can't come to the office.

Few companies these days actually offer full remote work in their own time zone - the allure of being able to "control" your employees by making them come into the office is just too strong and "productivity" is not something that can be easily measured, let alone discerned (not by the people who make the decisions, anyway).

hash0··on Ask HN: What if there was an 8th day of the week?
Huh, now THAT adresses a real need: An off-work day between Saturday (aka "catch up with chores you had to neglect because you were working") and "have to dread/mentally prepare for the upcoming work week"-Sunday!

I'd call it "Funday", actually: A day for pure, unalloyed relaxation. Everyone would have time to visit friends and hang out with family.

hash0··on Ask HN: How do people keep track of organizational knowledge?
In my line of work (IT Operations for a large international bank), we came up with a classification framework that tried to gauge information along two axes: Importance and Frequency of Use.

Importance is the more obvious one - there is critical info you absolutely need as a basis to understand the system, then there is also minor details. The difference is in an emergency, lack of the former will break your attempt to fix the system, lack of the latter will merely inconvenience you.

The Frequence of Use axis is the one that brought value to our operations when we introduced it. That's the question "How often will I need this info?". Regularly re-occuring, detailled procedures need to be accessible easily, so they go to a prominent Confluence page. But then there is information that you will hardly ever need, some arcanae about the system that only the old timers knew but that needed to be fixed in writing.

The most vexing bits of info are those that are highly important but are rarely ever needed. Do you plonk them into Confluence? Might not be the best idea because then you don't know how to quickly find it when need be. So we had an extra category for just that sort of thing which became our go-to info hub for all sorts of highly urgent but at first intractable issues with our system.

It does, thank you for your view on this!
hash0··on I Forgot to Get Excited
Part of the answer to this conundrum might be the "lightswitch effect": Lightswitches are ubiquitous and easy to use, so you stop thinking about them, take them completely for granted and miss the bigger picture that even 150 years ago, this would have been considered not a small technical miracle!

LLMs seem to fall squarely into that category - the threshold to using them is incredibly low because you can "just talk to them" and they give back meaningful answers loaded with the sum total of human knowledge from the interwebs.

hash0··on Ask HN: Favourite science history book of the 20th century?
Agreed, but with one caveat: That is the book detailling the history of future science!
hash0··on Ask HN: Favourite science history book of the 20th century?
"Cosmos" by Carl Sagan - that book was a life changer for me and has been with me ever since.
hash0··on Ask HN: Do we need a support group for developers alienated by LLMs?
If I may ask: In what areas have you found the most acceleration in productivity? For me as an enthusiastic amateur programmer (whose enthusiasm is, arguably, greater than my technical abilities) the only reliable and sustainable way to use AI in building software is to treat it like an exceptionally knowledgeable (though not perfect!), infinitely patient tutor that guides me through programming problems I run into. The minute I relinquish control and let it just write code for me I am doomed because AI cannot fix its own mistakes in anything of medium complexity or above - and then I have to dig down and try to understand code I haven't written which is, in my opinion, worse than having had to write it myself in the first place.
hash0··on Ask HN: Do we need a support group for developers alienated by LLMs?
I wouldn't consider myself an SWE, just an amateur programmer, so this is an honest question: In your opinion, is there such a case where the usage of AI in software engineering has either sped up the dev time or improved product reliability (or even both)?
hash0··on Ask HN: How long has it been since you last opened Stack Overflow?
I started using LLMs in 2022, quickly turned away because the things obivously made up stuff I am a certified expert it. Back to Stack Overflow. Came around to LLMs in late 2025 again as they rolled it out in my workplace and quickly succumbed to them becoming my all-knowing, (almost) flawless, infinitely patient teacher - that was the last time I opened Stack Overflow. AI never tells me I'm dumb for asking a question, never passive-aggressively shoves genuine questions aside. And AI can just be as critical in dissecting my flawed approaches to problems as SO could be (which is good!) but without the toxicity.
hash0··on Ask HN: Do we need a support group for developers alienated by LLMs?
Seems like the need for a support group depends on whether the recent advent of LLMs in your specific workplace has led you to become a Centaur ("I'm now a 10x SWE") or a Reverse Centaur ("this is rapidly sucking the joy this job once held for me"). So, yes, there is very definitely a need for this as there are definitely people seeing themselves cast as the latter.
hash0··on Why is music so much easier for AI than code?
Seems to me that both music and language fall into the same category of "patterns whose consumption will trigger a highly subjective experience (pleasurable or repulsive)". AIs as pattern matching machines can do this pretty well by now. Coding, however, is a separate category, one where cold, hard logic reigns supreme. Code is not consumed to illicit a subjective response but to work, fullfil its job - which might explain the gap between these two.
hash0··on Show HN: Isnad – A Python framework that uses 1,200-yearold Islamic logic for AI
"...when a claim passes through five AI agents, how should trust propagate from one step to the next? I spent months trying to solve it."

Maybe I am naive here, but wouldn't a sane person try to turn a rational eye on the problem stated therein and - maybe -think "what if there is a way to avoid chaining of AI agents at all?".

hash0··on How to avoid dementia – what the science says
The waterfall graph in the middle of this article is worth looking this up.
hash0··on You don't need to work on hard problems (2020)
tl;dr Instead of solving textbook-style hard problems, "find the easiest problem whose solution would be useful".
hash0··on Finnish Supermarket truck appears in Khamenei funeral procession
"The company said the most likely explanation is that one of its transport partners sold the vehicle without removing K Group branding, despite contractual obligations requiring decals to be removed before resale."

I say this was done intentionally - the Iranian Revolutionary Guards surely can put that extra income from advertisement during a highly televised event to good use.

hash0··on Egypt's New Delta Megaproject
Hopefully it will fare better in its ecological and economical impact than the Assuan dam - which, I will never tire to say, has to put almost its entire electricity output to the production of fertilizers that no longer deposit naturally along the Nile's banks because of the dam(n).
hash0··on Fable Built a 3D Model of Aristotle's Cognitive Architecture
This is a stunning idea and execution! I am glad I clicked on that link and spent a couple of minutes on it. Serious kudos, good Sir/Ma'am/[respectful appellation of your choosing].
hash0··on Is it common for devs to be confident in code but awkward in conversations?
Not sure if I fully qualify as a dev but I, for one, are rather confident in conversation. But with code, there is only two modes: Either I am the biggest idiot whoever disgraced Earth's surface or I am the absolute titanic Übergod for whom no problem is too hard to solve. There is nothing in between which is pretty vexing.
hash0··on AI coding is a nightmare. Am I the only one experiencing this?
Pretty sure their strategy is "hype it up, stuff it down EVERYONE's throat, once everyone is hooked and the tool is indispensable, make them pay for it. And rachet up the prices every quarter".
hash0··on Ask HN: Once you make your money from vibe coding innumerable products, then?
You're most welcome, Good Sir/Ma'am/[respectful appellation of your choosing]! ;)
hash0··on Ask HN: Once you make your money from vibe coding innumerable products, then?
I apologize, I did not mean to rain on your parade - maybe I am a kind of "half empty" person.

Please, keep your enthusiasm up! In a world full of cynics (me included), it's refreshing to see people throwing themselves into their projects with zest and passion.

hash0··on AI coding is a nightmare. Am I the only one experiencing this?
You mention two very specific aspects of AI producing code:

- "It hyper-focuses on the current task and couldn't care less if its changes break other parts of the system." - "Long context = instant brain damage"

This is why I quickly discovered that I had to turn AI into a knowledgable, patient tutor rather than let it code for me. I am thoroughly at the helm for all decisions big and small - I don't let AI touch the code anymore.

hash0··on Ask HN: Once you make your money from vibe coding innumerable products, then?
"Now I'm thinking - once it does happen - what will I spend my time dooing? Espeically, with AI?"

Not "once" - the word you are looking for is "if". And a pretty big if at that...

hash0··on I'm opening VSCode less and less every day
I would really like to know how people work on anything more complicated than a single page website without using an IDE/Editor any more - in my experience, AI is just not up to the task of managing multi-file projects without me having a very sharp eye on what it does.
