Same here. I'm not in the gaming industry but I'll refuse going to the US for work these days. Not that that happens a lot because I work for an EU company, but we do have a sizeable US presence. But just no, I'm not willing to travel there anymore.

I'm very 'woke' by US and even European standards so I just wouldn't feel safe there. I don't expect any problems with my employer even if I'd be asked to go and refuse.

I think the worst thing about the golden age of symbolic AI was that there was never a systematic approach to reasoning about uncertainty.

The MYCIN system was rather good at medical diagnostics and like other systems of the time had an ad-hoc procedure to deal with uncertainty which is essential in medical diagnosis.

The problem is that is not enough to say "predicate A has a 80% of being true" but rather if you have predicate A and B you have to consider the probability of all four of (AB, (not A) B, A (not B), (not A) (not B)) and if it is N predicates you have to consider joint probabilities over 2^N possible situations and that's a lot.

For any particular situation the values are correlated and you don't really need to consider all those contingencies but a general-purpose reasoning system with logic has to be able to handle the worst case. It seems that deep learning systems take shortcuts that work much of the time but may well hit the wall on how accurate they can be because of that.

Show HN: SaludyVos – Book lab tests with home sample collection in Buenos Aires
by rishness | 2026-03-09 13:27:19+00:00
¡Hola de Argentina!

Recently, I launched SaludyVos in Buenos Aires. It is a digital health platform that helps expats/digital nomads book a wide range of laboratory tests with home sample collection and no medical order required. We also provide a teleconsult with a local English-speaking doctor to review the results.

If you are in Buenos Aires or know someone who is currently here in this beautiful city, do recommend us. We have been growing fast, and our customers love the convenience.

Because the why can be completely unrelated to the code (odd business requirements etc). The code can be known to be non-optimal but it is still the correct way because the embedded system used in product XYZ has some dumb chip in it that needs it this weird way etc. Or the CEO loves this way of doing things and fires everyone who touches it. So many possibilities, most technical projects have a huge amount of politics and weird legacy behavior that someone depends on (including on internal stuff, private methods are not guaranteed to not be used by a client for example). And comments can guard against it, both for the dev and the reviewer. Hell we currently have clients depend on the exact internal layout of some PDF reports, and not even the rendered layout but that actual definitions.

IIRC Linus Torvalds said in the Linus Tech Tips video he was in that he thinks many of the bluescreens Windows gets a bad rep for are actually bitflips that happen due to most desktops not using ECC-Memory.

Our north star is creating a broader developer platform for AI media generation that includes observability, with fine-tuned vision models as a judge to monitor production traffic.

We also have a model arena and showdown page that ranks models by task, so you can find the best model for e.g. photorealism: https://lumenfall.ai/leaderboard

Our stack is Rails for the dashboard and Cloudflare Workers (Typescript / Hono) for the engine.

Heading down the links of this blog ends up at https://github.com/gfrmin/credence, which claims to be an agentic harness that keeps track of usefulness of tools separately and beats LangChain at a benchmark.

LangChain… Now that’s a name I haven’t heard in a long, long time..

Anyway, that’s a cool idea. But also his blog posts include phrases like “That’s not intelligence, it’s just <x> with vibes.” Urg. Slop of the worst sort.

But, like I said, I like the idea of keeping a running tally of what tool uses are useful in which circumstances, and consulting the oracle for recommended uses. I feel slightly icky digging into the code though; there’s a type of (usually brilliant) engineer that assumes when they see success that it’s a) wrong, and b) because everybody’s stupid, and sadly, some of that tone comes through the claude sonnet 4.0 writing used to put this blog together.

I do often wonder with this kind of thing whether an unspoken aspect of it is about not depleting the country's fossil fuels

From what I understand Ireland has very little natural gas, very little coal and a not particularly large amount of peat. If they didn't shift towards importing all of that would be gone in the very near future.

It's a bit weird how it gets branded as a solely green move when there's clearly other motives for it.

5% per minute is not extremely fast. Simple cycle gas turbine (peaker) plants routinely go 0 to 100% in less than 10 minutes. Nuclear plants can only hit 5% per minute in the 50 to 100% interval (per your own source).

And all of this is confused by the way the nuclear industry uses the term "load following". You'd think it means "changing the power output from moment to moment to match electricity demand" but for nuclear plants it means "changing from one pre-planned constant level to another pre-planned constant level, up to four times per day".[0] There are only three[1] sources of electricity that can be ramped freely enough to exactly match demand: hydro, simple-cycle gas turbines and batteries. All electrical supplies will need some of those three mixed in. Which is why France is still 10% hydro and 10% natural gas in their electricity supply.

0: Some of the most modern Russian plants can move to +-20% of their current target at 10% per minute, but "the number of such very fast
power variations is limited, and they are mainly reserved for emergency situations." per your source.

1: OK, there are some obsolete ways too, like diesel generators. At least obsolete at the scale of the electricity grid.

I've found my people. I discovered my love of programming in the 80s at the age of 10 on a TRS-80. But I'm not a kid anymore with infinite free time to learn new tech. I have a lot of responsibilities. So by the time I get up to speed on the latest and greatest, the industry has moved on. Claude has reinvigorated my love for buildings apps. I completed a side project in an afternoon. I built a custom app for my wife in a couple of days. I released an iOS app. And since my job does not allow for direct AI integration out of security concerns, I still get my fill of coding by hand. I resisted the AI movement at first but once I embraced it, it became a win-win for me.

> SQL Server has to convert every single value in the column to nvarchar before it can compare.

This of course is not true. It is a defect in Microsoft’s query planner. And the proof lies in the remedy.

The recommended solution is to convert the search argument type to match that of the index. The user is forced to discover the problem and adjust manually. SQL Server could just as well have done that automatically.

No information is lost converting nvarchar to varchar if the index is varchar. If the search argument is ‘’, no conversion from varchar will match it (unless the index data is UTF8, which the server should know).

This is a longstanding bug in SQLserver, and not the only one. Instead of patting ourselves on the back for avoiding what SQL Server “has to do”, we should be insisting it not do it. Anymore.

Isn't that a bit extreme? As a counterpoint, I find it useful to be able to pay for a train journey by tapping my card on an electronic reader - no representative of the company is there or otherwise witnesses me doing so - but I have entered into a contract whereby I am entitled to travel to a distant location. And I do want it to be a contract, because the transport company agrees to get me to my destination somehow even if the trains are cancelled. Perhaps the conditions of carriage may be somehow unsatisfactory to me, but the way in which I enter into the contract is almost entirely unrelated.

Reading charitably I think he means that it's a shortcut to gaining influence.

In the boomer sense of "go to the store and ask if they need help".

Trump "pushes" his way into things (because he's a disgusting bully), but it largely works.

I think the parent meant it in this way, that email pushes its way into peoples private box, but this is probably same as actually sending a letter to someone.

The question should really be what is the reservation price of existing buyers.

At some point the price will rise. But the value has to have risen for existing buyers to be ok with that - but can they perceive the value? Hmmm difficult to tell. Benchmarks are not an objective way to measure that.

In the long run google is most likely to acquire a serious cost advantage given their level of vertical integration.

It's not mindless brute-forcing, the details of the architecture, data, and training strategy still matter a lot (if you gave a modern datacenter to an AI researcher from the 60s they wouldn't get an LLM very quickly). The bitter lesson is that you should focus on adjusting your techniques so that they can take advantage of processing power to learn more about your problem themselves, instead of trying to hand-craft half the solution yourself to 'help' the part that's learning.

I was able to read the link through a non-paywalled friend link (thank you HeinanCA).

Ok so the issue was they were using Amazon Linux 2... Which in fairness has been practically deprecated for a while.

I mean, it's essentially a RHEL7 with frankenstein-style patches all the way up (new kernels etc).

Anyone who identifies as a 'loner', 'introverted', etc. is method acting. The label only matters if there are people to convey it to. Remember that the only reason you know of people claiming this, is because they said it to an audience, not themselves.

I am not sure it's a matter of how you frame the issue, to be honest, although I have seen this argument used quite a lot.

100% renewables is the exact opposite of "100% non-renewables" and that's including also oil, gas, etc. So "coal" is only a part of the 100% non renewables, but it seems your goal is to get rid of all the non renewables.

And here the question is: why would you want a single goal? Why 100% renewable?

What drives us should be: save where it makes sense, don't where it doesn't. Iterate every 10 years and recheck.

All these single radical goals are literally killing our economy and society. And I am not just talking about coal free or renewable.

Even the "let's tear down the windfarms" is dumb because it's radical and non sense.

Or unrelated, even this "we need to digitalize everything" (although given our jobs we would profit the most) can lead to a lot of problems (privacy, security, etc).

I don't know why we have become so radical in the last 20 years.

>It's about tracking your physical location via Tile trackers.

1. If the complaint is about non-consensual tracking, using a gadget that's specifically designed and advertised for tracking, and that you have to specifically go out and buy and put on your body is a terrible example.

2. Tile trackers have more or less been replaced with airtags and whatever google's equivalent is, which is designed in such a way that prevents companies from knowing its actual location.

Yes but you can actually have Copyparty run as a server similar to Jellyfin and have the same thing too?

Am I missing something that I am not looking at? But won't jellyfin have the same issue, I think that plex has servers that you can connect from outside but the GP wanted to move to jellyfin and I was talking about that.

And, you can even have plex like thing by just having Cloudflare Tunnels/Tailscale + Copyparty too.

In 2024, well after Covid, 88% of new electric capacity added in China came from renewables.

https://www.eia.gov/international/analysis/country/chn

Their existing grid uses coal because they have coal, just like the US uses gas because it has gas. And obviously as old coal plants are retired they're going to build new ones. They don't use the new plants for additional capacity. As they add more solar and storage, which they're building a lot of, they're going to absolutely crush the coal burning too. It's literally a national security issue for them.

Did Read; Take My Money

Temperature changing rubber pushing studs outwards that add grip as the tire cools, absolutely brilliant if the outer layers haven't been softened so far as to make the tire life impractical.

Upsides

- significant reduction in slide and sudden stop accidents

- significant drop in hydroplane events due to poor maintenance (the ride will be awful once the studs are exposed)

- possibly longer tire life

- incredible off road potential

- reduction in price of conventional full rubber tire

Downsides

- Increased road maintenance

- possibly decreased tire life

- increased pedestrian, consequential,and head on collision damage due to increased traction

- Decreased ride comfort as mass production will inevitably lead to increased tolerances

- which will also increase / complicate balance weighting which limits top speed rating

Exactly. We're basically living through the "distributed systems reliability" moment for agents. Traditional infra has circuit breakers, rate limiters, health checks — agents have nothing.

That's what I'm building: treat agent-to-LLM calls like microservice calls. Detect loops, enforce budgets, fail-open if the firewall itself crashes. Same patterns, new domain.

The interesting part is loop detection needs to be semantic, not just frequency-based. Two agents can politely argue in circles without ever triggering a rate limit.

The existence of temporary accommodation for workers in construction projects should not be the issue. It seems like this is a necessary and sensible thing.

The problem is with the quality of that accommodation.

It is also worth noting that there should not be an issue due to the fact that the accommodation provider also supplies accommodation for asylum seekers, because they should be providing acceptable accommodation to those people too.

You can probably add prisons to that list too.

Workers, immigrants, and prisoners all deserve reasonable living conditions. Why people are being housed in a place is irrelevant.

The AI link in this story seems to be simply because there are construction projects involving AI, that seems rather spurious. They wont be the first or last construction projects. Those workers deserve (and probably don't get) the support they need whether they are building a data center, a Casino, or a hospital.

> If you use Renewable Energy Sources, it may happen there will be no wind or no sun.

Yes, but this rarely happens, so any potential solution should be designed around it being idle 99% of the time.

> Those power plants have about 1h cold start.

Gas turbines can spin up significantly faster. However, the weather is quite predictable, so it is unlikely that this will be needed. Besides, battery storage is the perfect solution as an ultra-fast ramp-up holdover source until the turbines are at 100%.

> Hence, in order to have RES you need to emit CO2.

Or you equip the handful of gas turbines you use to make up for that 1% gap in renewables with carbon capture? It's not ideal, but it is very much doable.

> Simply use nuclear power plants and do not bother with RES

... and have your electricity be even more expensive?

They tried to fit a lot of ragebait into this article and headline, but the TL;DR appears to be that this company wants to build temporary housing near construction sites so workers don’t have to commute as far if they don’t want to. The only actually criticism of the temporary housing is that it’s “gray” but they note it has access to a gym. Clicking a link to the other article describing them says they have “free steaks” and access to golf.

My cousin works in construction and some times gets job where the money is great but he has to drive 2 hours to the site and 2 hours home or even more. Temporary housing seems like it would be helpful while doing those jobs.

We never had particularly cheap energy. The recent increases in energy cost were largely driven by gas price increases due to the war in Ukraine.

> we've graduated from providing cheap energy to now importing most of our energy.

... Eh? We've always imported most of our energy. Or, well, okay, since about the mid 19th century we've imported most of our energy. All coal used in Moneypoint was imported. We do produce some of our own gas, but it is not and never has been enough. The fraction of energy that we import has actually fallen somewhat due to wind and solar.

Hey HN,

I got tired of AI agents (Cursor, Claude Code) instantly writing hundreds of lines of bad code from a misunderstood prompt, burning tokens and time.

We built Overture: an open-source MCP server that intercepts the agent's plan and renders it as an interactive graph. You can review dependencies, inject context into specific nodes, and approve the flowchart before execution starts.

Would love any technical feedback or thoughts on the approach.
by jerf | 2026-03-09 13:32:09+00:00
That would be a hypothesis, not a fact.

I'm not closed to it. You can check my comment history for frequent references to next-generation AIs that aren't architected like LLMs. But they're going to have to produce an AI of some sort that is better than the current ones, not hypothesize that it may be possible. We've got about 50 years of hypothesis about how wonderful such techniques may be and, by the new standards of 2026, precious few demonstrations of it.

Quoting from the article:

"Within five years, deep learning had consumed machine learning almost entirely. Not because the methods it displaced had stopped working, but because the money, the talent, and the prestige had moved elsewhere."

That one jumped right out at me because there's a slight-of-hand there. A more correct quote would be "Not because the methods it displaced had stopped working as well as they ever have, ..." Without that phrase, the implication that other techniques were doing just as well as our transformer-based LLMs is slipped in there, but it's manifestly false when brought up to conscious examination. Of course they haven't, unless they're in the form of some probably-beyond-top-secret AI in some government lab somewhere. Decades have been poured into them and they have not produced high-quality AIs.

Anyone who wants to produce that next-gen leap had probably better have some clear eyes about what the competition is.

This argument that we have to self destruct to have the moral highground just keeps getting repeated, for maybe two decades now.

We, as in the West, got there first because we are luckier/better organised/evil colonialists/whatever, take your pick it doesn't matter.

Huh, you think the equator is better for datacenters? I've never heard that.

I mean, there's a reason Luleå is a popular datacenter spot: access to hydro & wind- but also "free cooling"; datacenters create a lot of heat and having a cold environment makes it easier to maintain ambient temperatures that are sustainable with lower energy consumption.

Additionally, people tend to prefer their servers are in geopolitically stable countries that are less likely to be bombed or undergo civil war (and the US likes to ensure civil war in countries that have a lot of oil) - and you want your datacenters to avoid any environmental hazards like earthquakes.

I can't imagine preferring the equator for datacenters.

There's been a non-zero number of occasions since that time where I've observed situations that mirror the trust-based challenges Advogato sought to solve.

It is perhaps telling that as prescient as Raph's work on trust metrics was he later moved on to the notoriously challenging realm of font rendering--presumably because it seemed more tractable. :D
