That’s not bad pricing wise. There’s very very little prosumer gear that’s multi gigabit and it’s all much higher price, or it’s just a PC with several NICs.
If and when we move to hyperfibre this is going to be pretty high up on the list.
I’m not sure that lossy compression on vectors is strictly impossible.
You can do things like store less colour information and simplify splines so that curves are less complex.
Lots of places also have variable limit signs that get updated based on traffic, accidents etc.
Here in NZ those seem to all be marked on the speed limit maps as 100km/h even if in some places the signs never go above 80.
Ngauranga Gorge is one such location and I believe has the country’s highest grossing speed camera.
Everything burns up regardless of size. Big things might not finish burning by the time they hit the ground.
You need either enough thrust to slow you to ~mach 2, or a heat shield to do the same by aerobraking.
It’s called aerobraking for a reason: you’re using friction to turn kinetic energy into heat to slow down, but that heat goes into the air and your heat shield instead of brake pads and rotors.
Oh, I’ve had the name for a lot longer than that.
As Someone Somewhere, I urge you to post more.
603 for maglevs, 574.8 for steel rail, set in France in 2007 by a hotted up, modified TGV.
China holds the record for a stock train at 487, set in 2010.
(all per Wikipedia)
It looks like the article might be implying that they will be the fastest trains operating in revenue service when they enter service, but that surely needs to be demonstrated with a production train in revenue service.
Regular trains don’t run underground. Lots of opencast mines exist .
Basically all mines have an above ground terminal where whatever you mined is unloaded from your underground trains, lifts, haul trucks or whatever else onto storage piles, then loaded onto the actual long distance trains.
If the mine entry is up a mountain, then the trip down from that point will be a net energy producer regardless of anything else.
I wouldn’t be surprised if there are electrified railway lines doing the same. Regenerate large amounts of energy into the grid while descending loaded; consume a relatively small amount of energy to haul the empty train back uphill.
If you’re thinking of that CGI crane lifting concrete blocks, it’s unfortunately a really bad idea.
Pumped hydro stores energy by lifting weight uphill, instead. Water is basically the cheapest thing you can get per tonne, and is easy to contain and move.
To store useful amounts of energy using gravity, you need pretty large elevation differences and millions of tonnes of mass to move.
Those specific cases are learned behaviour, but general purpose cruelty and theft is something that’s been around longer than capitalism has, and has to be unlearned as kids, not learned.
Anyone attempting to claim that humans are inherently humane has not met many humans.
I feel dumber having read that.
Banning a whole country because you disliked a company?
Dealing with stuff that’s ‘almost working’ is often harder than starting from scratch; ask any tradesperson.
They also apparently cannot get their heads around the fact that people might give you a discount if you advertise their brand. Ad-supported pricing has been around for a long time; it’s not some voodoo.
Until the day comes that I get a letter in the mail from the government saying, “Here’s how much you paid in taxes, if you’re cool with that then please disregard”, I will not be satisfied.
NZ does that. More accurately, they email you to tell you that there’s a letter available online - I don’t think they send physical mail by default.
Then they pay any refund straight into your nominated bank account.
It’s also torches and everything after the regulator, which run at much lower pressure. At least in NZ
I think it might be because they’re connected and disconnected regularly so misconnection is a common problem, even with colour coding. Gas work on houses involves actually putting the fittings on pipe and is done by people who should be concentrating more on that rather than on what they’re about to weld/cut.
“Lossless” isn’t the term you want; that refers to not lossily compressing the main data. Lossless compression or storage of media is very rare outside of text and sometimes audio, because it ends up so large.
You want to preserve metadata. That applies regardless of how lossy the data compression is.
I’ve heard flammable gas uses reverse (left hand) thread to prevent cross connection. At least for welding gases in NZ; not sure about natural gas.
Any hard drive can fail at any time with or without warning. Worrying too much about individual drive families’ reliability isn’t worth it if you’re dealing with few drives. Worry instead about backups and recovery plans in case it does happen.
Bigger drives have significantly lower power usage per TB, and cost per TB is lowest around 12-16TB. Bigger drives also lets you fit more storage in a given box. Drives 12TB and up are all currently helium filled which run significantly cooler.
Two preferred options in the data hoarder communities are shucking (external drives are cheaper than internal, so remove the case) and buying refurb or grey market drives from vendors like Server Supply or Water Panther. In both cases, the savings are usually big enough that you can simply buy an extra drive to make up for any loss of warranty.
Under US$15/TB is typically a ‘good’ price.
For media serving and deep storage, HDDs are still fine and cheap. For general file storage, consider SSDs to improve IOPS.
Honestly sounds like Hanlon’s Razor on Google’s part. No collusion necessary, just incompetence.
