Black mesa upholds more modern graphical standards, but it's still fundamentally the same game. The same disconnect applies.

The subtle point is there are plenty of new journeys we can take together.

You absolutely could not get me to come within striking distance of that thing. In situations like this the best solution is the chainsaw protocol: When a running chainsaw is spinning around on the ground, you don't try to go grab it. You keep everyone clear until it runs out of gas.

This is fucking terrifying. At multiple points people try to retrain it's arms and it doesn't tip a safety and shut down the motor drives. There's no E-stop button. This thing might be human shaped, but all I see is an industrial robot programmed to make a series of fast flailing motions in a volume inhabited by unsuspecting people with zero thought to keeping them safe. It does not know you are there, does not know it's own strength, and it will not stop just because it has already broken bone.

Could you build a solid ring? no, absolutely not. it would break up no matter what you made it out of.

Could you launch millions of solar satellites into orbit around the moon? sure, anything's possible with enough money.

though there's really no benefit vs just putting them on earth. it's not *that* much more efficient. unless you're an island nation without a lot of land area.

You have already posted these videos before, and two aren't even relevant. (blackstarting) The one which DOES address these inverters doesn't meaningfully engage with the current cost or trends in cost of the technology, though it does note (15:03) that they're "improving rapidly." TLDR These videos (really, video) tell you the technology exists, and I'm telling you that they're becoming cheaper and more common. As with many things solar, the burden is much less than even a few years ago.

That's not a problem ("what if the sun/wind goes away for a whole week") you will ever be able to solve with a single source of renewable energy in a single location. No installation is ever designed to cope with this. It's why we have an interconnected power grid, with a variety of sources, so that power plants in single areas can be taken offline.

I know what you said, and that is what I meant. I just didn't feel like typing out "GRID LEADING inverters that SIMULATE INERTIA." I don't know if you know this, but GRID LEADING inverters that SIMULATE INERTIA have been coming down in price rapidly because, to quite myself, they're "not significantly more complicated than existing grid equipment" ie. the regular inverters you think I meant.

I think you need to watch this video: https://www.youtube.com/watch?v=KtQ9nt2ZeGM

The batteries are already being built into the solar installations and included in the cost. The inverters themselves are also not significantly more complicated than existing grid equipment and will drop in cost a hell of a lot as the technology becomes more commonly deployed. The only reason it's expensive now is it literally didn't exist a few years ago, so there isn't much supply of units atm.

PP is still leader because there's nobody else who really fits the bill and has the name recognition to take the spotlight, even though PP is massively unlikable on his own without trudeau around to sling mud at. they don't really have anyone who can articulate a vision and really compete on that front, so it's just sling, sling sling and hope some mud eventually sticks.

2/2 ok for left leaning voters. very different tone to fun-loving trudeau. He also campaigned strong on "stand-up-to-trump" when "51st state" was in the news, where as PP looks more cozy and likely to sell out. carney is also a lot better at describing a plan, where as PP just nixes stuff. voters for the left-wing NDP also realized they'd need to hold their nose and vote liberal or the vote would split and PP would win (unthinkable). these factors combined got carney in with a near-majority.

this brings us to late 2024, by which time the liberals under trudeau were MASSIVELY unpopular, and PP was the latest guy in the conservative conga line to be the attack dog. PP at least superficially looks less smarmy than scheer did in photos. It was looking like PP would finally break the streak and sweep in with a solid conservative majority, when turdeau finally read the writing on the wall and resigned. his replacement, carney, is a banker who bills as more centrist while still being 1/2

there was a long stretch of fairly "normal" conservative rule through the 2000's, before the liberals got in with trudeau. he was new and fresh and charismatic compared to the previous conservative guy. the years dragged on, and trudeau couldn't keep out of scandals, and the conservatives learned they could make bank getting people pissed over scandals. they never quite found the right asshole who could whip up anger but also win an election, and still haven't, even as polling shifted their way.

DDR5 also has nasty thermal overheating/stability issues, but that's a whole other can of worms. (L1techs has a good explainer video on this if you'd like more info)

3 weeks ago | Likes 1 Dislikes 0

A quick side note: you may have heard about DDR5 having "on die" ECC. If you read the DDR5 spec, this is purely to raise the reliability of ordinary DDR5 to the level of normal DDR4. DDR5 is higher density and therefore the memory cells are leakier, and there is only enough protection to compensate for that.

If you want resilience to memory errors, you have to use end-to-end "traditional" ECC *as well* in the same way you would need traditional ECC for DDR4.

It's very possible that windows' reputation for being unstable was at least partly earned by consumer memory not having any ability to correct errors, ie. the hardware's fault.

I dunno about you, but I don't think the average person can replace soldered ram. They're going to struggle with anything that's not a pluggable stick. Hot air rework is by definition a tool only used by repair specialists.

They developed a huristic for determining if it was a memory bitflip. The true answer is public in the firefox source code (firefox is open source) but it's very likely they did something like read back the code of firefox to determine if it matched what's on disk.

They also run a 2nd stage for all such crashes which performs a memory stress test, and *half* of those found defective ram. (bitflips can still happen in non-ECC ram due to particles from space, which are the other half)

This applies to every program on your computer, and the OS too. Memory corruption down in the hardware doesn't care what the app is. Firefox just happens to be the one that rolled out this test.

Memory corruption is way more common that people think. It's just that without error-correcting memory you have no way to know it happened. A bunch of researchers registered variants of "microsoft.com" that were one bitflip off (not letter, meaning no typos) and tens of thousands of computers tried to connect.

Every single one of them had experienced memory corruption at that exact moment, at the exact spot holding the address, a rare combination that tells you this must be happening constantly

3 weeks ago | Likes 3 Dislikes 1

depends. some of these are things like "you ran out of ram, so the OS killed firefox to fix it" and there are probably other causes mixed in too.

3 weeks ago | Likes 8 Dislikes 1

TLDR: 10% of firefox crashes are caused by memory corruption. ie firefox tried to store some data and your hardware gave wrong data back. This rises to 15% if you exclude crashes due to people running out of ram.

Half of these are caused by people having defective ram that is constantly spewing errors, and half by random chance ie. a particle from space passing through a ram chip.

Error Correcting Code (ECC) ram as *standard* would alert people to the former and completely fix the latter.

why are you basing your estimate of the utility of information entirely on how much you like the person? I don't like the guy, in fact I think just about anyone even related to the current AI buildouts is an asshat, but that doesn't mean this isn't a useful peek into what's going on in the industry and how it's operating.

But I guess you're just content to stick your head in the sand and scream LALALA.

these guys are skipping the infrastructure and pofits, and building the datacenters anyway. Those are somebody else's problem.

Nice fantasy. Those have astoundingly poor performance. They're not going to overtake dedicated tensor cores. What did you think dedicated AI hardware meant?

Nice theory, completely misses the point. Nvidia don't need to develop anything. They just need to use their technology and position to strangle any potential better technology in it's crib. And that's exactly what they're doing. I don't know if you understand this, but we don't live in a universe where the best technology always wins. It rarely does.
