Comment Re:Search Everything (Score 1) 35

Windows search used to be kind of OK. Never as good as Everything, but Everything didn't exist for most of history. But they really fucked it up somewhere along the line, which I didn't notice because I was using Everything, and now it's very challenging to construct a complex search without learning a whole new language of keywords.

Now that most people have a fast internet connection

In the case of BitTorrent, even the fastest Internet connection won't get you a lot of successful peer connections if your ISP blocks all inbound TCP connections.

If youtube goes away, streaming video won't disappear, some new ecosystem will grow in its place.

Such a new ecosystem already has grown, as I understand it. It's called getting Netflix, HBO Max, Paramount+, Disney+/Hulu, Peacock, Prime Video, or Apple TV to accept your pitch and fund it. These take the place of cable television channels in the pre-broadband economy. And there are still a lot more pilot screenplays than budget to produce all of them.

FWIW, healthcare insurance shareholders aren't getting rich

The top shareholders and the executives are. Hence Luigi.

The main driver of high cost in the US is the providers, not the insurers

The insurers are motivated to drive health care costs up by the so-called affordable care act, which caps their profits at a percentage of those costs. Since they're not the ones paying the bills, the insured are (and via APTC, the government is, which means the taxpayers are) they want those costs to go up because they get to collect more profit. You need to not ignore reality if you want it to make sense.

"Medicare for all" is a sham.

"sabbede" is a dumbfuck.

Medicare is age restricted

The proposals address that, because the people who write them are not dumbfucks. Also, there are already people who are less than 65 getting Medicare. They have disabilities. The BASIS code for their Medicare eligibility is "D" instead of "A", for disabled instead of aged. Maybe don't fucking try to educate me about things you know fuck-all about? TBF that means you shouldn't try to educate me about anything, but that would be just peachy.

You are speaking irrelevant nonsense. LLMs are trained in words

They are not. They are trained in tokens. Tokens do not align with word boundaries, and an arbitrary word can be tokenized in many different ways.

and they think in words

They do not. They don't even think in tokens. The process is: words are split to tokens, tokens point to an embedding position (latent space) while RoPE encodes a relative position, and all reasoning is done within latent space, which is not at all verbal (concepts are directions in latent space, and math is done on concepts, not words).

Also, a note: when spec'ing a generator, you need to know how much you're planning to use it vs. batteries. If it's only going to be used rarely, you prefer low mass, low volume, low cost, and low maintenance when unused (at the cost of low efficiency and higher maintenance in use), whereas if it's going to be used a lot, you prefer high efficiency and low maintenance cost in use, even if at the cost of higher mass, volume, cost, and maintenance when unused. In the former case, you'd prefer to allocate that extra mass, volume, and money into a larger battery pack.

That's why you don't use a tiny petrol generator? Diesel generator efficiencies are roughly:

Small backup generator (1-15kW): ~20-28%
Midsize backup generator (20-200kW): ~30-35%
Large industrial generator (200-2000kW): ~35-42%

Also, ironically this company's plan of the trailer providing a boost will actually make the tractor less efficient. ICE engines use "brake specific fuel consumption" (BSFC) graphs to plot their efficiencies across different RPMs and different torques. You can see an example for a small diesel engine here. Note that they require very high torque conditions and relatively high power conditions to be efficient. You can change the balance between torque and RPM within a given power band (blue) via gearing but gearing doesn't change what power band you're in. If you're in a low power band, you're fundamentally forced into inefficiency (note also that you're not going to be driving around at 1000 RPM just over a stall all the time).

Indeed, if you were forced into a low power band, you'd actually be better off with a series hybrid powertrain, as the engine can alternate between operating in an efficient powerband and shutting down. Of course, parallel hybrids are more efficient than series (albeit with added complexity and mass).

Comment Re:Real advantage is the assist, not the braking. (Score 0) 44

The major advantage is being able to use an engine that's worthless for acceleration, e.g. Atkinson cycle. All ICEs are most efficient at a specific point on the torque/RPM chart so that's not the differentiator.

Regen braking is the biggest benefit in the city. It's essentially irrelevant everywhere else, but whether it matters most or not depends on where you're driving.

Unfortunately, the math doesn't work that way (even ignoring that a 400kWh battery is very small). Battery packs taper the closer you get to full, they're not a constant power all the way. Unless your battery pack can take 400kW at 80%, you're not charging that quickly.

Also, while 40 mins is fine in Europe (breaks: 45 minutes every 4,5 hours of driving... though using 70% of a 400kWh pack on a loaded class 8 truck going even at a slow 80kph will only take you 2 1/2h of driving in "average" conditions, so the truck's range is fundamentally undersized), the US is 30 minutes total break in 11 hours of driving, so ~6 hours on your first leg and ~5h on your second leg with 30 minutes to fill that 5h of driving. And US speed limits are usually faster for trucks than in the EU, so higher consumption. EU really needs 600kWh and >=600kW charging, while the US needs 800-1000kWh and >MW charging.

Note that in all of this we're assuming efficient-shaped trucks (Tesla Semi or the like), not your typical EU bricks, along with a well optimized powertrain and an efficient tyre config. If not, you need to increase those packs and charge powers further.
