Have a look at Bjorn Nyland's YouTube channel. He compares Chinese EVs, and also Teslas with US and Chinese batteries.

I haven't watched the video, but are you sure that are all EVs? There was a massive car fire in the UK last year, blamed on an EV, but it turned out to be a fossil SUV.

Amazon can afford solar panels and batteries, so their electricity unit cost is going to be extremely low. Even when they need to pull from the grid, they can do it overnight when prices are lowest.

EVs cost a lot less than fossils to maintain. No engine oil or filters, no exhaust system, no spark plugs, no fuel pump or injectors, no water pump, no variable gearbox (on most), even the brakes hardly get used thanks to regen. For commercial operators with fleets of vehicles, those savings add up fast. You can bet that the vehicles Amazon uses are very simple, and the only complexities are things they would fit to a fossil like telematics so they can see where they are and how they are driving.

As for consumer EVs, there are loads of simple ones. The Nissan Leaf is a good example, one of the first and a very straightforward machine. It's easy to replace or upgrade the batteries, the BMS handles it without any reprogramming. It all works fine without the infotainment unit even being installed, and the base models didn't have telematics.

Might be worth looking at variable tariffs. For March-May the demand for electricity generation goes to zero in California on a regular basis, and even more often over the summer. While you might not pay $0 for it, the price should go way down.

Or get some solar panels and charge from those. Unfortunately it's the people who can't afford such things or shift their demand to cheaper times that end up paying the most as well, exacerbating inequality.

Maybe it's different in the US, but in the UK large consumers of electricity pay a variable rate based on demand. It's fairly predictable over a period of 48 hours, but it does vary. It's only retail customers that get a fixed rate, although with a tiny bit of effort you can save a lot of money by opting out of that.

Secure Boot ensures that the OS boot files have not been modified. One popular technique malware used was to replace ntfs.sys (the NTFS filesystem driver) or the SATA driver with one that hid the malware's own files. Virus scanners could tell you were infected, but couldn't remove the infection. The only way to get rid of it was to boot a Linux CD with anti-virus software from someone like Kaspersky, which used its own NTFS and SATA drivers. Or move the HDD to another machine for scanning etc.

That became impossible once Secure Boot was checking that those parts of the OS were not modified. To be honest, I would talk someone into installing Linux over the phone if they couldn't disable Secure Boot in the BIOS, chances are I'd be stuck doing tech support forever. Unless their PC shipped with it, you can guarantee something important will be broken.

Submission + - Study: Alphabetical order of surnames may affect grading (umich.edu)

AmiMoJo writes: Knowing your ABCs is essential to academic success, but having a last name starting with A, B or C might also help make the grade. An analysis by University of Michigan researchers of more than 30 million grading records from U-M finds students with alphabetically lower-ranked names receive lower grades. This is due to sequential grading biases and the default order of students’ submissions in Canvas — the most widely used online learning management system — which is based on alphabetical rank of their surnames.

What’s more, the researchers found, those alphabetically disadvantaged students receive comments that are notably more negative and less polite, and exhibit lower grading quality measured by post-grade complaints from students.

Have you had even a cursory look at China's infrastructure projects? Two thirds of the entire world's high speed rail lines, with the project only starting in the mid 2000s. They are now upgrading some parts to maglev at 600 kph.

Same thing with metro systems and other light rail. Then you get to roads...

For all it's faults, China is undeniably the leader in infrastructure projects. No other country comes close. And I say that not as a fan, but as a warning that we need to get our shit together if we want to compete. China built all that high speed rail in the time the UK was talking about maybe doing one short line and then cancelling most of it.

The Japanese have demonstrated precision landing on the Moon without GPS. They used various sensors, including cameras scanning the horizon to match it to the expected view.

The race for sample return is now on with China. They are likely to do a simple mission that aims to just get something back, rather than maximize scientific value, much like Apollo 11. Starship might be in that race, it's not really clear yet. They are contracted to put astronauts on the Moon next year, although it looks like it will slip to 2026, but either way they really need to put a lot of effort into getting that milestone done before looking to Mars.

Landing on Mars is very different to the Moon, due to Mars having more gravity and an atmosphere. Plus the spacecraft needs to survive a much longer mission just to get there, and you can't iterate so rapidly due to less frequent launch windows and the long transit time before you discover that something doesn't work right.

The other issue is fuel. If you have a small lander and ascent vehicle you can take all the fuel with you. Something the size of Starship may need to produce fuel on the ground.

The Chinese have not announced how they intend to do it, but since they aren't developing anything like Starship it seems like they will probably go the small lander/ascent vehicle and in-orbit rendezvous method.

That's demonstrably untrue. Look at the Windows XP days, an OS that launched without even enabling the firewall. Then there was Vista that everyone hated because Microsoft beefed up the security model, resulting in large numbers of security warnings. And now the same people are moaning about Windows 11 requiring TPM 2 for securing the boot process, which was of course one of the favourite attack vectors back before Secure Boot became mandatory for OEMs.

Meanwhile, as Linux's popularity increases, so does the amount of malware. Not because Linux is getting worse, just because there is more effort to exploit it now.

It's not clear that Linux would fix anything here. If the feature you need happens to be open source and actually works, great, but if it's some proprietary extension that your vendor offers or you didn't pay them to fix the bugs, you are on your own.

That is assuming that the software you need is even Linux native. If you are running it in WINE then good luck.
