Am I the only person on the planet who still opens the garage door with, you know, my hands? Is that completely crazy? Am *I* crazy?

Around my neighborhood almost no one parks in the garage (they park in their driveway, or the street). The garage is where you store stuff (and you rarely open the garage door).

I thought the garage was where people put their guest bedroom. :-)

Comment Samsung always pisses on Samsung (Score 1) 87

Samsung is collection of several companies and if you've ever spent any time working with them you quickly realize that they all prioritize other Samsung companies below other customers. I don't know whether it's because of anti-trust concerns, or market strategy, or just rivalry, but I've never seen any Samsung company that operated any differently. I worked quite a bit with Samsung Mobile and S.LSI, who are even quite interdependent (though S.LSI depends more on Samsung Mobile than the reverse), and they constantly ignored and even dissed one another.

The problem is that it's not intuitive that there's a special case traffic rule for that and I don't remember it ever being brought up in driver's ed

There's no way your driver's ed class failed to mention that traffic is required to stop for school buses with their red lights flashing, and I think it's unlikely that your written test failed to include a question about school zone and school bus rules. Mine (Utah) certainly did.

I guess neither humans or bots are trained well on that. It's pretty stupid anyway. The kids should cross the street at normal crossings like everyone else, not just anywhere a huge yellow beast stops and flips out a sign.

In rural areas, like where I live, there aren't any marked crossings, and there really isn't any reasonable place to put them. If you mark a crossing it would only ever be used by the one or two houses near it, and only by school children, because there's really no need for anyone to walk across the street otherwise. The school buses stop directly in front of each child's house. There aren't any locations where a bus could pick up multiple children without making them have to walk an unreasonable distance, so each kid's house is a stop.

Also, the speed limit on my road is 45 mph, and cars routinely drive 55 mph... so having the "huge yellow beast" with flashing red lights and a flipped-out, flashing red stop sign is definitely necessary.

That was the only pad Russia had which has the infrastructure necessary to launch humans into space

Not entirely correct. It is the only *active* pad with that infrastructure. There are decommissioned pads that have been used for manned missions in the past. What state they are currently in is an unknown, but it has been speculated that equipment could be salvaged from them to repair the damaged pad.

The direct fuel injection does seem to cause more trouble than it's worth.

Low tension rings cause more trouble than their worth Low viscosity oil causes more trouble than it's worth Stop-start causes more trouble than it's worth Variable displacement causes more trouble than it's worth Integral dual volute turbocharging causes more trouble than it's worth And yes, direct injection causes more trouble than it's worth.

The extreme CAFE mileage requirements have driven manufacturers to make a large number of terrible engineering choices in ICE drive trains. Extreme CAFE mileage requirements have greatly contributed to the excessive cost of vehicles and the excessive cost of repairs.

Yep. CAFE-style regulation is the wrong way to attempt to reduce carbon emissions. The right way is to impose a carbon tax, then let consumers vote with their wallets and engineers work to make the right tradeoffs to meet customer demand. My guess is that consumers would choose to buy the more fuel-efficient vehicles and engineers might make the same tradeoffs... but now it would be clear that those tradeoffs are worthwhile.

Gas is not cheap.

Gas is pretty much exactly at its long-term, inflation-adjusted average price, and right where it was in the 1950s. Since then, it was a little higher in the 70s, a little lower in the 90s, a little higher in the early 2000s, but we're now back at the long-term normal price.

See https://afdc.energy.gov/data/1...

Whether the normal price of gas is "cheap" or "expensive" depends on your income and lifestyle, I'd think.

Russia doesn't have the ability for manned spaceflight. ergo they don't have cosmonauts any more.

Tell that to the folks on ISS who ride back and forth on Soyuz all the time. A couple of people went up to ISS from Russia just one week ago.

To be fair, at the moment, future ISS launches from Russia won't be possible because of some launch pad damage incurred by a recent launch, but Russia still has the capability of launching crewed rockets into space from other pads. They just can't send any to ISS right now because its orbital inclination is incompatible with the locations of those other pads while staying within the fuel capacity limits of their rockets.

Comment Re:The old auto makers are fucked. (Score 1) 253

Cars have been getting shittier for decades now. You never noticed because American marketing convinced Americans that 100K miles on any car engine is dangerously out of fashion.

What are you talking about? On average, engines last 150k to 200k miles in the U.S., complete with CAFE standards.

And the main goal of the current CAFE standards was to push hybrids and electric vehicles. Manufacturers rigging the game by trying to make pure ICE cars with ridiculous mileage is an unanticipated negative side effect, mostly because the folks coming up with the rules did not expect automakers to be so stupid that they would do something like that.

Comment Re:a much needed move? (Score 1) 253

A "much-needed move" would be to allow BYD cars to be sold here and let the free market economics (that conservatives ostensibly claim to love) sort everything out.

I'm not going to argue about the merit of allowing BYD or not. This is only about free market economics. BYD is heavily subsidized, and their entry in the market would skew any possible free market economics.

This is an appropriate place for tariffs. Not ridiculous, exclusionary tariffs like we have, but tariffs carefully calibrated to offset the subsidies as precisely as possible, putting BYD's cars on a level playing field against US EVs. I have great faith in free market capitalism and dislike anything that distorts the market, but sometimes you need to use regulation to correct for external market distortions.

When I purchased my latest car, which has this crazy 1 year 10K recommended oil change interval (OCI) while using 0w20 oil, I searched and found online manuals from various other countries. In countries where OCI/emissions are not regulated (various former Soviet republics), the car manual states to use 10w30 oil and 5K OCI recommended for the same car.

For the most part, oil change schedules are set so that car dealers can make money off of mandatory service so that you keep your warranty. In reality, if you periodically change your filter, use a filter with a smaller pore size, and use synthetic oil, there's at least potentially no need to change the oil at all, at least within the typical lifetime of a passenger car.

Semi goes 1 million miles without an oil change.

0W-20 runs in the American motor in order to barely eek out another 1MPG to barely meet the CAFE standards necessary to ship product. 5W-30 runs in the EU motor because it’s the best viscosity for the damn engine. Which they determined long ago with engineering and testing, both in lab and real world results.

Now pull those engines apart after 100K miles and see why we need to get rid of CAFE bullshit. The American environment isn’t being “saved” by forcing Americans to replace their disposable cars before the fucking loan is even fully paid.

The problem is not the CAFE standards per se. The problem is that they are trying to meet them by playing tricks instead of with actual design changes. And even though they come with thinner engine oil, 90% of people will put standard oil into the cars at the first change. So they get higher MPG for the first 5,000 miles, and then the same as they did before the CAFE standards.

I suppose that in theory, you could argue that the standards are flawed for not requiring normal oil weights during testing, but that's about it.

The correct way to hit the MPG targets is to use more electric drive trains. If you make your cars hybrids, you can improve the efficiency of the electric drive train and find ways to engineer the vehicles to weigh less by using more modern materials, and you won't have to work too hard to hit the standards.

Better yet, push actual EVs, which typically have an eMPG of 100+. If just one-third of your vehicles get 130 eMPG and the rest get 30 MPG, you're averaging about 53 MPG already.

It's ability to hover, and fixing itself to the deck allows for a much expanded launch envelope.

How so? I don't see how hovering makes any difference at all... it's just a waste of fuel, increasing gravity loss. It's nicer from a controllability standpoint, but SpaceX has clearly perfected the hoverslam maneuver and once you have that down it makes more sense than to waste fuel hovering and translating. Bolting itself into the deck helps with rough seas, I suppose, but it seems unlikely you'd want to try landing in very rough conditions anyway.

Spacex doesn't seem to care for doing this all that often any more.

Nah. They do it when it makes sense. They don't do it for Starlink launches because it's cheaper to launch a slightly lighter load and shorten turnaround time, to avoid waiting for the droneship to ferry the rocket back to land. Plus their launch cadence is so high that they'd need a big fleet of droneships. So they reserve those for paying customers who need the greater capacity. I don't think anything about New Glenn's capabilities changes those calculations.

That's actually a good question. Inks have changed somewhat over the past 5,000 years, and there's no particular reason to think that tattoo inks have been equally mobile across this timeframe.

But now we come to a deeper point. Basically, tattoos (as I've always understand it) are surgically-engineered scars, with the scar tissue supposedly locking the ink in place. It's quite probable that my understanding is wrong - this isn't exactly an area I've really looked into in any depth, so the probability of me being right is rather slim. Nonetheless, if I had been correct, then you might well expect the stuff to stay there. Skin is highly permeable, but scar tissue less so. As long as the molecules exceed the size that can migrate, then you'd think it would be fine.

That it isn't fine shows that one or more of these ideas must be wrong.
