  • ECC (and other methods) write the corrected value back to memory

    That was my understanding (it corrects the error and writes the good value back to RAM), but now I’m not so sure! I imagine it must do that, otherwise a second bit flip would actually corrupt the RAM, and the RAM manufacturer would want to reduce that risk.

    Regular ECC adds an extra parity bit for each byte. For each byte of memory, it can correct an error in one bit, and detect but not correct an error in two bits, so they wouldn’t want a one bit error to linger for longer than it needs to.


  • Prices will go up before black friday

    It’s before Black Friday now :P

    Amazon show a “lowest price in 30 days” badge if the price is the lowest in the past 30 days, so companies that sell their products on Amazon will sometimes raise the price 30 days before Black Friday.

    Some companies will make units specifically for black friday. Usually cheaper, less features, and sometimes less reliable.

    This has always been the case. Same with outlets - some items at outlet stores are specifically made to be sold at the outlet.





  • A better use of your time is to improve documentation. Developers generally hate documentation so it’s often in need of improvement. Rewrite confusing sentences. Add tutorials that are missing. Things like that. You don’t necessarily have to be a good developer or even understand the code of the project; you just have to have some knowledge of the project as an end user.











  • Makes sense.

    My wife and I don’t commute very far so an EV is fine for us even if we can only charge it with 120V initially (until we install a proper charger in our garage). We’ve got a BMW iX on order.

    Tesla is opening superchargers to all brands eventually. That’ll help a lot, as will the inevitable changes that’ll happen to gas stations where they replace some pumps with EV chargers.

    Range is definitely an issue, but it’s improving over time. 10 years ago, the average EV range was around 100 miles. I know BMW have tested a prototype car with ~600 mile range, and that tech should hopefully come with their Neue Klasse vehicles some time in 2026/2027. The Lucid Air gets around 500 miles range. Our current gas car (2012 Mazda 3) only gets around 360 miles until the gas light comes on, so it’s not actually that different for us.
