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).

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.

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).

It will be faster only for code that uses/is optimized for that specific extension. And the examples you give are not really correct.

If you add a supercharger you will get more power, but if the car's transmission is not upgraded, you might just get some broken gears and shafts.

If you add more solar panels to your roof, you might exceed the inverter power, and the panels will not bring benefits.

It's true that you will benefit from the changes above, but not just by themselves - something else needs to change so you can benefit. And in the case of the M4 and these extensions, the software needs do be changed and also to have an use case for these extensions.

"But look how thin it is!"

The article says "100 times greater than TDK’s current battery in mass production" but they are not referring to the current LiIon/LiPo batteries, but the current _solid state_ battery. The capacity per liter of the new solid state battery is less than 2x of the current phone batteries (1000Wh/liter vs 5-700Wh/liter for LiPo). So no, you cannot replace one phone battery with a coin cell with the same battery life.

That seems to be a modified bike, with a head tube extension plus lots of random spacers, and lots of accessories. It's probably used as a very comfortable road/gravel bike.

I (as a non-mac user, but impulse buyer of odd camera gear) appreciate the "exclusively for Mac" label put just after the fold. I usually have to read pages (about software) on HN for minutes before finding out (in a footer or "get it here" link) that it's Mac-only. This way I just know it's not for me and I can continue with my boring life.

Unfortunately, Romanian bears are brown bears (Ursus arctos), not black (Ursus americanus). They are not easily scared by people and encounters with them can be very dangerous.

In the 'olden days', when external displays and projectors were scarce, we used this feature for collaboration/presentations in non text-heavy interactions. Four people can sit at a table around it and they can all see the screen when it's flat on the table, albeit one of them would see it upside down.

Now I mostly use it for comfortable position in bed, as many others say.

It's not a video card, it does not have video outputs.

They mean database agnostic - that you can easily/magically migrate your application from a DBMS to another and the ORM will handle it for you. That usually works only for trivial databases and does not include data migration.

Yeah, the sleep is a mess with new hardware (and MS also does not help, with the new OS sleep). I have a "creator"-targeted MB from Gigabyte and it does sleep, but if it wakes up immediately after I put it to sleep (because of a mouse move), it does a series of 7-8 BIOS initalizations/restarts and it resets the full BIOS in the process.

MS is still "the best" in this case. Searching for Firefox on a fresh Windows install (with Edge) will show Chrome and Opera as first two options (keyword ads), then Firefox. And then, when you download the Firefox installer, you are announced that it could harm your device.

The way Amazon works now (or at least my understanding from past articles and seller interactions outside of the platform), for some of the items you are not guaranteed that you received the item that your specific seller sent to the fulfillment center. If an item has multiple vendors, you will receive probably the closest one, not the one from the seller you selected. If that item is fake (even though the seller you selected is selling original items), reviewing the seller would mean penalizing the good actor.

I had an interaction ~10 years ago with an Amazon seller that kept also their online store. They did not deliver directly to my country but directed me to their Amazon store that did deliver. I ended up getting a slightly different version (same item but a different revision). Talking to the seller, it was not one that they sent to Amazon; it also came from a warehouse in a different country.

Isn't the item in the link just an acrylic glass with patterns lasered on? With persistence of vision you can get animations, so I would say that's the fancier one.

Insolation is higher in California, with the same solar panel surface you can probably get double the energy over a year, compared to France.

Hydrogen storage is not something that you really want to do at home, especially in "saving up" quantities. It is quite happy to explode, you need tremendous pressures and low temperatures for efficient storage, and also hard to contain (many "normal" materials are permeable to hydrogen). [1]

There is another reason why (especially cheap/"normal") thermal cameras have low frame rates. Basically higher (than 9!) fps cameras can be restricted for export and travel under ITAR (International Traffic in Arms Regulations).
