Correcting anything on Google Maps takes years. You report the issue (clearly visible against the aerial photo, for example a road that appears on the map but it's not actually there - and Maps insists routing you through) to the void and after 2 years you come back and it's still not corrected.

You need a lot of batteries to store the energy needed overnight and you have to plan for (lots of) days without sun. At my latitude (45N) the difference in solar production between summer and winter is 5x. Even with batteries, you still need a backup for a week of bad weather; so you have to choose between increasing the solar production 20x to have enough power generated in cloudy days or have a backup coal/gas/something else plant.

It's global data, "here" is not US, and it's solar+wind, not only solar. Summer months have a different definition depending on hemisphere and solar production maximums depend heavily on latitude.

One thing to note: These Xeons have quad memory channels, that usually means double the bandwidth of an equivalent desktop CPU, if you populate all the slots.

I have a dual E5-2667 v2 server with 512GB DDR3 and it's quite nice, the memory bandwidth is higher than of a DDR4 desktop with a way newer CPU, even though it's ECC and registered.

Not really. They use aluminum fins because they are way lighter and cheaper. The copper tubes are actually heat pipes that transfer the heat through liquid/vapor phase change. And copper is used because the liquid inside is water (aluminum would corrode) and they are also easier to bend into shape (aluminum fatigues easier with bends, and pores would allow the liquid to escape).

In the energy results they are comparing their novel water block cold plate against an air cooled facility, not against a similar water-cooled facility.

There are "simple" hardware tokens that allow for that - you have to enter the amount and part of the destination IBAN and they generate a 2FA number based on that + probably the same number generator it uses for logins.

ADSB is not mandatory in the US below FL100 or FL180 (10000/18000 feet), that covers most helicopter flights.

It depends also on the website you are using to track. I have an ADSB receiver that publishes to multiple tracking websites (the same data, unfiltered), and not all of them publish all the data. Flightradar24 doesn't show most of the military aircraft - I can see them on my local tracking interface but they are not shown on their website.

Also, batteries will degrade faster over time when they start to degrade, because they need more frequent charging. Their internal resistance increase and that promotes heat buildup during fast charging/discharging, another thing that promotes degradation. Slow charge/discharge cycles also help with heat management.

Having a Windows 11 corporate laptop with a domain/Entra login, I actually trust it more than a home Windows 11 with a Microsoft account. Because if I lock myself out, I have a contact (corporate support) that is actually interested in helping me recover everything. With a Microsoft account it's a mess. I had so many problems with Microsoft accounts that I lost count of how many I have, and most are broken in some way, because of different issues and different service integrations over time. The Skype account is now useless. I never recovered my paid Minecraft account after one event. With a machine with a local account, now I have to be very careful on what I click related to MS accounts, because trying to solve various issues with Teams, I managed to get the local account linked with that MS account. I spent hours trying to recover a different account after I randomly filled one nagging question about birth date - who wants to give the real birth date to Microsoft - and then I got locked out because I said was underage :). So yes, one of the big issues is the push to have a linked OS account where you have to rely on MS support to solve your issues, otherwise you basically get locked out of your machine and other things you paid for.

Also, domain policies offer more control over the corporate PCs (this is how some of the MS spying is shut off on corporate PCs; it's debatable if the corporate spying added by other domain policies is an improvement).

The usual problems with this approach are 1) the roof is not big enough for solar panels to power multiple chargers and 2) the power is generated when people are not at home (and probably using their car to go to work).

Yeah, it's basically dying and living on old fame. We had to buy a license a few years ago for a customer who needed support for some things that PDFBox did not support, Of course it's not just a license, you have to buy multiple licenses for production, development and so on. It was okay until we hit a bug, iText could not read some form fields correctly and was basically changing the PDF contents on save. We opened a support ticket with all the details, sample files and code to reproduce. The ticket stayed open for a year. After a year they asked us to pay for more support. We showed them the open ticket and never heard from them again.

The problem is that a cable saying that it's something does not mean that it actually conforms to the standard and can deliver that speed/power. And proper testing requires complex hardware.

I'm not complaining, I'm just saying that the higher numbers of that benchmark result do not translate directly to better performance for all software you run. Deep learning as it is right now is probably the main application that benefits from this extension (and probably the reason why it was added in hardware at this point in time).
