hnuser123456··on UK Green party drops longstanding opposition to nuclear power
I find it fairly amusing that "green" parties were ever opposed to nuclear power. It was clearly lobbying by fossil fuel energy interests. If we're gonna generate electricity at night without burning coal, oil or gas, we need nuclear. Storing solar and wind overnight is an even more absurd proposition than nuclear power plants. Burning more fossil fuels is even more absurd than nuclear power plants.
hnuser123456··on I love software rendering
TAA has a pretty bad reputation among many gamers for being too blurry. TSR (temporal super resolution) is a newer implementation that's overall sharper, better at eliminating "jaggies", and performant, without visible ghosting or artifacting.
hnuser123456··on BIPM decides to stop adding leap seconds to UTC
This essentially means being less anal about ensuring the earth has the exact same clock time at the exact same earth-sun-relative rotational position. Turns out the earth spins up and slows down semi-randomly with a magnitude big enough to require positive or negative leap seconds every few years, and it's just not worth the effort. Leap minutes might only be needed around every 100 years, but that would still be annoying, so they dropped all the way to leap hours, probably not needed for thousands of years. As long as the sun rises in the morning and sets in the afternoon, that saves on a lot of frequent minor adjustments. Timezones are already an hour wide anyways, and the sun isn't in the same spot when you're on the western vs eastern edges.

Sure, you could also run a relativistic simulation of the solar system, galaxy, and cosmos to establish a more monotonic clock and calendar independent of imperfect orbital parameters, but that's a bit much for discerning whether or not it's lunchtime.

hnuser123456··on BIPM decides to stop adding leap seconds to UTC
A practical solution. As long as we can keep 12:00 near high noon and 00:00 near "high midnight(?)", that should be good enough.
hnuser123456··on Hole Punch: Sling your spaceship around gravitational fields
Nice domain name
hnuser123456··on How did AMD Ryzen get 50% faster in two years?
Their successors had more tangible performance improvements in everyday applications, so yes they were quickly forgotten. Also, it was a reduction in max core count from 10 to 8, intel changes sockets too often, and 14nm+++++.

To prevent HF from arguing for additional regulation.

No, it would be an indirect market effect.
hnuser123456··on Hugging Face is billing OpenAI $100M for hacking it
If HF holds OAI accountable to pay for "rogue" agent behavior, the rest of the business world will be more afraid of adopting AI, which will reduce demand for Nvidia GPUs, possibly at a long-term cost to Nvidia much greater than $100M.

Whether or not a human is putting in any effort to ensure the safeguards are enabled and working should be the million dollar question. And even more expensive if the safeguards were deliberately disabled for a "our AI is so smart we can't contain it" marketing piece.

hnuser123456··on Steam Frame starts at $1059
SteamVR's frame interpolation and warping is extremely well-polished. I would go into VRChat clubs, enable everyone's full-detail avatar, and I could go down to about 20fps with head tracking still feeling comfortable. Not sure if the onboard processors can do as good of a job though.
hnuser123456··on iPhone 18 Pro and iPhone 18 Pro Max
Yes, and TB5 also uses around 10x as much power, around 4W rather than 0.4W for USB3, which would consume the majority of the sustained power budget of the entire phone.
hnuser123456··on No Man's Sky Cosmos
FC3 is generally quite favorably reviewed. NMS could have been far more interesting if about 25% of the planets had relatively peaceful weather, wildlife, and sentinels, and had palatable color schemes, but near every single planet is either +200C, -200C, or radioactive, and the calm ones are lunar landscapes or barren.
hnuser123456··on California's new tire efficiency rules could save drivers $1B a year
If they're looking to improve tire energy efficiency with regulation, shouldn't they also make it a citable offense to drive with tires inflated below 30psi? You could probably even train a ML algorithm to recognize images of vehicles with underinflated tires, and send the driver a reminder!
hnuser123456··on St Lucie Nuclear Reactor Unit 1 manually shutdown, 3 control rods drop into core
The rod holding mechanisms require active power to hold the rods out of the reactor. It sounds like once in a while, a rod accidentally drops, which is infinitely preferable to the alternative, of once in a while a rod failing to drop. But that unplanned adjustment to reactivity means, you don't want to simply use other means to boost the reactivity back up (like reducing boric acid in the water), because once you get the rod back out, it'll be too reactive. So they insert a couple more rods and call it a shutdown to take a few days or weeks to investigate and perform maintenance. Sounds like this is a highly planned for and fairly routine procedure, if not ideal. I'm sure they'll find a couple reasons why the rod unexpectedly dropped, and make changes to prevent an identical incident in the future.
hnuser123456··on Mars Bar from 1991 found – and it's 20g bigger than today's
Because TVs can be made to show ads, especially if the manufacturer themselves partners with an ad network.
hnuser123456··on Making difficulty curves in games
Intuitively, people want to save up ammo because they never know when there's gonna be a big fight, and they don't want to be caught low on ammo.

I had the same experience, I was trying to be very accurate with the guns and thought, wow, there's hardly any ammo to pick up in this game. Partway through I got tired of being stingy and started being less careful, having fun going rambo, and suddenly ammo was spawning everywhere.

I think it would be much better if the game just spawned enough to max out your pools fairly early, so you can focus less on inventory and more on combat. Then they can adjust the size of the ammo pools to tune how accurate they want you to be.

Fair point.
hnuser123456··on Hardware backdoors in some x86 CPUs
It's a Mila, they're capacitive touch buttons but not a touchscreen. There's just a fan down, fan up, and mode button. Even still, I don't know how they got the calibration wrong enough at the factory that it can't detect a full-pressure thumb press.
hnuser123456··on My server is a phone now
Phones are very low power, likely just a slightly warm spot on the can that radiates, conducts, and convects the heat out. You could also use one of those peltier module phone coolers, to ensure the heat gets out of the phone and into the air faster.
hnuser123456··on My server is a phone now
You could throw the phone in an ammo canister, if the wifi AP is close enough. When I was building hobby quadcopters, which requires several ~half-pound batteries that are a chemistry optimized for maximum power density, a lot of guys recommended steel ammo cans for battery storage.
hnuser123456··on Can Intel finally beat ARM on performance per Watt?
You might want to try getting the Nvidia GPU working. They're several times faster than intel integrated, and browsers are a GPU-heavy application.

Intel keeps trying to say their integrated graphics are finally decently fast, but that's only a select few special models. Their high-volume chips continue to have integrated GPUs that are barely fast enough for web browsing.

hnuser123456··on US Military's cyber command unit grapples with cluster of deaths by suicide
Maybe cliche, but I think a lot of this is just trauma being passed down from one generation to the next. A lot of those people have an easy time imaging an angry puritan god in their head, and taking it out on others (and themselves). Cultural dogma is advertized as a unifying force, but is often implemented with unsavory methods. I think a lot of people would be fine with dropping much of the rhetoric, if only the rest could suppress their instinctive reaction to use the faux pas for their own gain, of someone else being the first to admit the dogma is smoke and mirrors.

While the way you talk is captivating, I don't think it's quite so direct, or at least not on the grander scale. Once you know that everyone is fallible, you are free.

This probably depends on if you've used it enough to make some playlists and give it an idea of the real music that you like.

I thought the whole issue with manifest v3 is that prevented extensions from being able to block connections? That DNS blocking is actual blocking, while the extension can only do filtering after the connections are made.
hnuser123456··on Hardware backdoors in some x86 CPUs
I recently got an air purifier. The touch button controls for adjusting the fan speed didn't seem to be working, so I emailed support.

They had me download their app, link the air purifier, and give them its MAC address. Then they asked me to try pressing each of the buttons a few times and email them back. I did so, and they responded that they re-calibrated the buttons using my touch samples. It worked.

The strange part is that nearly all the decently large publishers seem to be completely unable to predict when a game will be successful, because they seem unable to determine when a game is actually fun to play. So they will dump hundreds of millions into a game that nobody wants to play, get close to zero sales, and end up shutting down the game, laying off the studio, and having to find another way to make back the $100m+ they just burned.

Indie devs have the time and freedom to pursue any new ideas, and it seems like every couple of months a new indie game goes viral on Steam. But many of them are passion projects that were done in someone's spare time outside of their day job. If devs could give investors more confidence that a game will sell well or go viral if it hits a certain development stage, we could do a better job of directing game dev funding towards indie devs making truly fun games.

It has everywhere to dissipate heat, but only radiatively. But 140 AU from the Sun, there's not much incoming radiant flux.
hnuser123456··on Corners Don't Look Like That: Regarding Screenspace Ambient Occlusion (2012)
I think the prime example of SSAO being helpful was Fallout 3. FO3 has very simplistic lighting even for its time, kind of looking like "fullbright"/non-shaded mode in Source engine. SSAO, when it was added as a graphics driver feature, suddenly gave interiors depth that they were severely lacking, and while it didn't always look "realistic", it almost always looked much better than without.

hnuser123456··on Who's running all those tiny RPKI servers?
RPKI mainly makes the administrative side of the route database more formal and rigorous than previous internet routing registry implementations. The processes for using them to improve network security are discussed at https://manrs.org/

They have a neat dashboard at https://observatory.manrs.org/
