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.
In regions where winters are dark windy places tent to be not too far away. If both solar and wind both overbuild to the extent it makes sense (say 5x for solar and 2x for wind) and batteries cover a normal daily cycle you probably will need to burn gas on 10-20% of days which is not net zero but way way better than the current situation.
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).
I have to agree, I've also suffered account problems. I was locked out from an email address I used for 20 years. It refuses to take my password which is still valid. I've changed phone number since 20 years ago so can't use that and the security questions were nonsense as I was a teenager. Originally my account never had phone number, they insisted I add it when they integrated my Skype account perhaps. So I didn't expect access to that phone number to be a strong ongoing requirement.
With mirrorless cameras the focus switched from specialized sensors to on-CMOS contiuous exposure sensors, so movement is easy to detect. At this point the cameras have specialized AI hardware to run the models, and they also accept user input (on R5 MkII you can register up to ten people to prioritize focus on[1]). The focusing options are now very complex[2][3], and combined with lots of customization options on the camera's buttons you can have very specialized/personalized setups for different types of photography.
Sure, as I said in the first paragraph, AF is these days very impressive thanks to the large amount of data available (but of course this would have been too much data back in the day, when there wasn't nearly enough CPU power to process it fast enough). I wanted to give more historical context for how AF worked before fancy AI.
The AF settings, except those related to face/object recognition, haven't actually changed that much since the 7D Mk II days. The preset system is more general now and allows you to store and recall all AF settings rather than just the three tracking-related variables. The high-end DSLRs used to have six cases for different types of sports that you could modify but not rename.
