Apropos, some of the most wholesome community spirit I've seen in recent years has been amongst the degenerate gamblers of wallstreetbets.
EliRivers··on Analysis: EVs are now nine times cheaper than petrol or diesel to drive in UK
Well what if rather than a Tesla+, one bought a cheaper EV instead? In the UK, the Leapmotor T03 seems to go for around 16000 GBP new. That's actually not much more than an equivalent petrol car.
EliRivers··on Where's the Beef?: The lab-grown-meat revolution that wasn't
It was going to be celebrity meat. As in, genetically identical to celebrities. In some circles, it would become de rigueur to host dinner parties at which one served meat cultured from the people throwing the dinner party. I wanted to see that future.
EliRivers··on Socialism's Positive Rating Tops 40% for First Time
That's not the definition of socialism in any case.

In many cases it very much is the definition of socialism.

EliRivers··on Terrence Tao: AI Is Teaching Us Something Uncomfortable About Our Own Minds [video]
Yes, it is. Beyond simple examples, I've fixed segfaults by identifying the assembly where it happens, tracing that back to the lump of source where it happens, guessed which piece is accessing memory and deducing from surrounding code how it was meant to be protected against.

In that case, the pattern matching was against every segfault I've ever fixed, which is a lot, and traipsing through assembly, which is also a lot. Lots of experience in tracing back to source code. So did that. Matching patterns. Didn't understand the language, don't know what it's trying to do, but I know what memory access is (because I've seen the pattern "access memory" a lot in my life) and this piece of code must be matching that pattern; whatever this code is, it must be touching memory. Now scroll up and down to look for similar code in other places, that I also cannot read but I can see when things look the same; match the pattern of pieces that work with this piece that doesn't. Oh, this looks the same but it has this extra piece; part of the pattern matches, part does not. Matching patterns. What if I copy it, paste into the bad place, apply a single change to match the symbols I see in the bad place, and see what happens... fixed.

It's not something I do every day and it's not nearly as good as actually understanding it, but the problem was solved and I did not know what the code was trying to do or how to read it.

All the above aside, surely it must be possible, because we have machines that do exactly that. They're made of statistics and patterns and they're doing it. Right in front of us. There is nothing else in there and they're doing it right now.

Done it myself.

The fact that you have a long history in the business makes me think we're either talking about wildly different things and this is a mismatch of language and context, or you're deliberately trolling me.

It can take a good few years to get to the point that one no longer has to think and understand in a concrete language. There are whole sets of common mistakes that get made across languages and tools. I've fixed errors in Pascal, which I do not read, because the person writing it was clearly thinking in C and made a mistake in their C thinking which they then translated into Pascal. Luckily for me they used common C naming and layout for that piece so I matched the whole thing up to C patterns.

Copy paste errors are easier ones to see; cases where replicated code is clearly meant to be different in a few keys places or values, and whoever did it just missed one. Array errors are common, no matter how the array notation works in language du jour. The list goes on.

All that aside, we know it's possible because there are machines doing it right now. They are made of stats and patterns. There is nothing else in there.

EliRivers··on AI safety is mostly a sex cult
But AI extermination of humans is a well known problem we have no solution for

Sure, but the realm of fictional problems is so huge that we just can't come up with solutions to all of them. I like watching the Terminator movies (well, the first couple) as much as the next person but I can't be spending my time imagining how we could defeat skynet.

EliRivers··on Terrence Tao: AI Is Teaching Us Something Uncomfortable About Our Own Minds [video]
the entity needs to be able to solve your problem.

People have fixed software bugs with zero knowledge of what the code is doing and no knowledge of the programming language at hand, purely by statistical pattern matching. Solving the problem with no understanding of it beyond the idea that whatever it was, the right answer was probably something that kind of matched the kind of patterns found in things they'd seen before.

So what does it mean, "to be able to solve your problem"?

EliRivers··on U.S. State Department pauses immigrant visa applications
They sure do. US law presupposes that a tourist is secretly planning to stay in the US, and must demonstrate otherwise to the satisfaction of the assessor. There are a number of factors assessed, including things like ties to the applicant's home country - an existing job, ownership of property, family demands; basically, clearly having a life in that country that the applicant wants and needs to get back to.

Someone applying for a tourist visa, who recently had an immigration renewal denied, who has no life to get back to in their country of origin (because they built a life in the US) but clearly has a life in the US (owns property in the US, has family in the US, has work ties -maybe even still has a job in the US); that applicant is an enhanced overstayer risk and this increases the chances of being denied a tourist visa.

EliRivers··on U.S. State Department pauses immigrant visa applications
Is that true? Immigrants into Ireland hold an Irish Residence Permit, which is renewed in Ireland, at the office in Ireland. No need to leave Ireland.
EliRivers··on Credit Card Rewards Became a $9.2B Wealth Transfer
I've heard such people referred to as deadbeats.
EliRivers··on US Air Force jet engine manufacturing plagued by 'significant challenges'
I suspect but cannot prove that a lot of the issues the US is experiencing right now exerting itself around the globe, such as lack of regional logistics ports and long supply lines and less enthusiasm from allies to join in, would apply in spades to anyone who decided to have a serious pop at the continental USA (barring globe-spanning nuclear missiles, but nobody wants to start that war right now).

Looking like a big man in your near waters, no more than a few days away from a home port, is one achievement (and it is an achievement - many nations can't do this). Sustaining a war on the other side of a serious ocean or two is a game very few countries in the world can manage right now.

The US would look extraordinarily strong to anyone bringing a war to the US.

EliRivers··on In Australia, a home battery boom has helped cut wholesale power prices
To a degree, this is Australia in this case, no? Resources are extracted from Australia, exported to China, turned into high value goods and sold back to them. In this case, it's exactly what OP is happy about!
EliRivers··on AI agents lie, cheat and steal. That is putting off users
It's that which is still there even when we stop believing in it.

If every living creature on earth ended tomorrow there would be no individual realities, yet actual reality would continue.

Fines? The business pays the fine, I want personal responsibility. Prison time.
EliRivers··on 2027 memory capacity is reportedly sold out
This all sounds very hypothetical economic universe. In the real world, rich people do buy expensive things and do nothing with them.
EliRivers··on Exercise works for depression. So why isn't it treated like real medicine?
In some places it is. Some people can indeed be "prescribed" (it's not a prescription, it's a referral) exercise and a low-cost arrangement is made with a local gym and appropriate fitness coach. In the UK, such schemes have historically been 12 to 16 weeks and the costs are jointly met by the NHS and the participant (much as with prescribed drugs).
EliRivers··on Microsoft Comic Chat is now open source
A google search for the creator of the Comic Sans font, Vincent Connare, triggers a fun google Easter egg.
EliRivers··on Australian energy retailers must offer three hours of free daytime electricity
"If something actually saves money then it doesn't require a subsidy because people would be doing it regardless."

Yet people frequently don't. This assertion and reality disagree.

EliRivers··on You're Not a Better Engineer Because You Type Git Commands by Hand
A rebase that can't just fast-forward?

That you know what that is makes you the right kind of person to be delegating it to an LLM; you can be trusted to use the LLM for this sort of thing because you understand what the problem is, what the right outcome should be, and how to know when it's been done correctly.

It's the person sitting behind you who doesn't understand any of those words who is going to do something dangerous at LLM-accelerated speed I'm concerned about.

EliRivers··on The Internet I Grew Up with Doesn't Exist Anymore
Purely for the fun of thinking about it, and not just to be awkward:

We owned a heavy, wooden CRT TV set from the 1970s or 1980s that hid all buttons behind a fake, black "speaker" that you could press to pop open. A decade or two after we had tossed this TV into our barn for disposal, my brother and I took turns hitting the glass screen as hard as we could with a baseball bat.

It never left a mark, regardless of how hard we hit it. Why don't we produce that quality anymore?

I would hazard that given the inflation adjusted price of a mid-range TV appears to have dropped about 99 percent since 1975, if we were willing to pay 100 times as much for a TV as we actually do here in the year 2026, we could have one made out of bulletproof glass too :)

EliRivers··on The Doorman's Fallacy in action
(I find ways to make it worth my while..)

I understand that somewhere is Australia is a supermarket which appears to be generating its own carrots in that it sells far more carrots than ever arrive, but is a black hole for parsnips; the store should be exploding with parsnips given the difference between amount delivered and amount sold, yet mysteriously there's just the one bin of parsnips visible.

EliRivers··on Ford AI hiccups push carmaker to rehire ‘gray beard’ inspectors
A friend of mine prepared an arsenal of hooks and the like to address this and LLMs still disobey them at times.

It's a model of language, yes? Trained on a big corpus of text.

I have read a lot of stories and accounts in which people were told not to do something and inevitably they did it. Like, lots. Far more than stories and accounts in which people were told not to do something and they then didn't do it.

If I'm reading a story or account of something, and it's really hammered home that they've been told not to do something, it's kind of inevitable that they will then do that. I'm not even an LLM and I noticed that's the way these things usually go.

So is an LLM just doing what it's been trained to do? Sometimes in the stories and accounts, there's a whole lot of time and tension before the bad thing happens, but that's just part of the fun.

EliRivers··on Crypto in 2026: Oh, This Is the Bad Place
each time I become familiar with a business it seems like we're actually causing most of the problems we solve.

Do you mean, in general, as a society/culture, or are you just having an incredible run of jobs where each time that business is the problem?

EliRivers··on Epidurals are a miracle technology
extremely biologically conserved process

This seems just plain wrong. It is not at all extremely biologically conserved.

Pregnancy and birth varies wildly across species. Not conserved. For primates, it's got problems; in humans, pregnancy is an absolute mess. The birth itself is historically one of the most dangerous things a woman can do, and remains not exactly a walk in the park even with the best of modern interventions.

EliRivers··on The room the economy can't see
"it is that in practice there is probably going to be a soft ban on this sort of space"

I looked around in my area, and the is not a soft ban on this sort of space. No need to guess about probabilities. How about in the country where you live? No need to guess; what's the reality?

EliRivers··on The 2-Year Apartment Rule
Who has cavity wall insulation removed? The effect on your heating bill is going to be much worse than a small amount of mould

Some of these houses have been transformed into being unfit for human habitation due to the damp and mould. In some cases, the botched insulation has resulted in an increase in heating costs (along with the damp and mold). Some have suffered structural damage due to the botched insulation, costing tens of thousands to repair.

EliRivers··on The Case for Free Online Books (2014)
"We required the students to buy the book"

This was always so odd to me. I used to think it was just a US weird thing but I understand it happens in many more countries as well (and maybe in my own country as well; I did go through my first degree literally two decades ago, and only at one university). When I went through my first degree, the lecturer provided the material - lectures and some handouts. Every so often there would be a reference to some book for some particular additional topic, but it was never required.

EliRivers··on Ask HN: What was your "oh shit" moment with GenAI?
Code reviews. Code reviews in theory done by humans, but containing copy-pasted inane statements of the obvious. Questions that really did no more than demonstrate a lack of context. Code reviews no longer an educational opportunity for the reviewer, a way they learn and stress their own understanding to create a better product and become a better person, destroyed by the siren song of GenAI producing comments that on the surface seem so helpful and sensible.

"Uh Oh" realization of what these models can do?

The code reviews was just how I first saw it, but the rot goes deeper. The "uh oh" was my realisation of how much these can damage people's professional development. These people will never get better at their job than they are right now.

A lot of what else GenAI does is great, but this is an "Uh oh" indeed.
