Comment Re:More wasted RAM (Score 1) 149

The original Macbook in 2006 had only 512 megabytes

A 512 MB module cost $100-$200 in 2006. Sold in an $1000 machine. 10% of the cost.

And now a macbook air costs order of magnitude the same, but the RAM they're putting in it.... $10-20 (1-2% of the cost).

I wonder if that difference in cost is going to some other part of the machine or into margins?

(I know Apple don't pay retail prices for their RAM, which is what I quoted here, the actual percentage of cost will be lower)

The main reason is Europe commonly has 3 phase AC service even to residential areas, with lower current per phase than North America delivers over a single split phase. To fully utilize what's available for AC charging in Europe, you need 3 AC pins on the charge port, where North America only needs 2 for the high and low side of the one phase.

Europe never used J1772 because they needed 3 pins, in NA when J1772 came out DC charging wasn't yet a thing and when it did start gaining ground, the high voltage pins were undersized for the currents DC fast charging provides without room to make them larger and stay compatible, so both CCS and CHAdeMO utilize a completely separate set of DC pins. NACS was designed with DC fast charging in mind, the high voltage pins are physically bigger and the car can use one set for both AC and DC charging, with a set of contactors inside the car to route it to the right onboard charger module. NACS is less useful in other markets because it doesn't provide the third AC pin, there's no point in every car sold in the US taking on the added expense of supporting 3 phase AC charging when 99.999% of them would never use it, and cars in markets where 3 phase are common need it to support efficient AC charging.

10 years ago, SHA1 was something you could sensibly store your passwords in.

Uh? No. SHA1 has been vulnerable to faster-than-brute-force attacks since 2005

NIST and most other real security professionals were recommending against using SHA1 since 2010/2011-ish.

Unlike you, I do not claim to be a security professional, but even I know SHA1 has been unsafe for a far longer than a decade.

I feel sorry for your clients.

rich western nations, which at this point cannot producing meaningful CO2 reductions *snip* Well except Germany of course, fuck you

CO2 (metric tons in 2020) per capita:

Germany's: 7.72
US: 13.68
Australia: 15.22
Singapore: 9.45

But Germany gets the fuck you? I don't think I'd hire you for your critical thinking skills.
