Checked how to receive those with SDR. Turns out they are very low power and you need to basically touch the tire. Also the transmit in minute intervals. Bit exactly a a smoking gun in terms of mass surveillance.

At Quobyte we are working on a highly scalable and fault-tolerant software storage system built around a parallel file system core. Our customers use us for large scale AI and HPC clusters in the enterprise and research, k8s and OpenStack infrastructures, and as a scalable backend for SaaS products. There are Quobyte clusters which span tens of thousands of machines and slurp 100s of GB/s!
Under the hood, we have built a full-stack fault-tolerant parallel file system, with everything from kernel development over our own replicated database system design to distributed algorithms (Paxos!) and performance. In short: lots of real-world challenging and fun problems!
We work as a highly efficient engineering team, ship frequently, do code reviews, and have lots of unit and integration testing. If you’re passionate about systems, we might be the right place for you!

Queues tend to be always full or always empty (see queueing theory). There is no steady state with a half full queue.
For NVMe in particular you will have a hard time filling their queues. Your perceived performance is mostly latency, as there is hardly an application that can submit enough concurrent requests.
Inverters have more electronic parts, but the parts themselves are very off-the-shelf, and the electronic design is pretty straightforward.
Inverters are still fairly expensive for a couple reasons;
Firstly economies of scale. A residential site buys 1 inverter, but 10 to 20 panels. A commercial site has an even bigger ratio.
Secondly Inverters are the bit that connects to the grid. So there are regulatory requirements which need to be tested for. And likely tested in multiple different jurisdictions.
Panels on the other hand are "difficult" to produce in volume. Largely because of the quality of raw silicon that is required. Its not that the panels themselves are complex, but the supplier chain to them is.
Sure but with a 20 year life span it's not like you can easily cut people off from the them. An interruption in supply has an enormous lead time to build a solution.
Panels are often quoted has having a 20 year (or 25 year) lifespan. But it doesn't really work like that.
Panels degrade a bit (about 0.7%) every year. So after 25 years or so they're down to 80% of rated power. Or, put another way, after 25 years they're still delivering 80% of rated power.
Depending on space, it may be advantageous to replace panels at some point. Or you might add more and leave those alone.
But they don't just "stop working" - the performance drop off is pretty linear.

At Quobyte, we are working on the Data Center File System (DCFS), a highly scalable and fault-tolerant software storage system built around a parallel file system core. Customers use Quobyte DCFS for ML and HPC clusters in industry and academia, k8s and OpenStack infrastructures, streaming, web mail, post production, origin and CGI clusters, and as a scalable backend for SaaS products. There are Quobyte DCFS clusters which span thousands of machines and crunch 100s of GB/s!
Under the hood, DCFS is a full-stack storage system, written in Java and C++. The engineering work covers everything from kernel development over our own replicated database system design to distributed algorithms (Paxos!) and performance. In short: lots of real-world challenging and fun problems! We work as a highly efficient engineering team, and do mandatory code reviews, lots of unit and integration testing,
For the consumer, maybe not, other than a delay of some years.
In terms of having the industry? Absolutely. How many other areas of "tech" has Europe basically punted on and ceded to Americans? Currently there's some gnashing of teeth across the pond for how there's no real European equivalent to the big US cloud providers (AWS, Azure, GCP).
There doesn't have to be an equivalent of everything, I wouldn't want to use US cloud because of price and governance. At most I use the "cloudy" services and rent "capacity" from a European provider, companies are fleeing the cloud. They're done subsidizing Amazon deliveries.
MobilEye and Mercedes works on self-driving, so does BMW. It's probably not Waymo quality, but just because there aren't cars on the (wide and car friendly) roads doesn't mean nothing is happening.
Meanwhile Europe has solid infrastructure for electricity (esp France), ASML has no competition, Carl Zeizz is world leading in optics, there's probably a Leica LIDAR in the Waymo cars... I mean while we're throwing pies and bringing up other markets..
My old boss was working on a project with Leica where he was working with some partner on self-driving industrial machines, they we're using Leica gear for collosion avoidance and such.
Europe doesn't need self-driving cars, we have alternative modes of transportation. Where it's needed (mines and industry) it's already there. And whatever modern car you're driving here has ADAS which helps make driving comforable.
Yes, it's fine to give up the lead in any one subsector, but Europe is so far behind in tech industries in general. It's not just cloud services or self driving cars, look at SpaceX and Starlink: Europe has no equivalent to either, and is many years from gaining one (I'm aware of some plans, but they're far away from being able to actually launch, and some are dubious besides).
Both major smartphones OSes? Run by American companies. Major desktop OSes? Two by American companies, one originally started by a Finn, who still manages it...and he moved to Oregon.
But you don't have to take an American's word for it, just read Mario Draghi's report. The man loves Europe, deeply understands the European economy, and has a whole lot to say: https://en.m.wikipedia.org/wiki/Draghi_report
So any b2c thing where you're going to abuse your customers is American, what an achievement!
There's no denying America has done good in some industries, but when it comes at the cost of societies weak I can't help but think it doesn't matter.
SpaceX and Starklink aren't very important to me, I don't know who they're important for except Ukraine, boat and RV owners.
The report says we must invest in electricity infrastructure, well sure so the dude compares against China and USA at the same time? Crumbling infrastructure is the definition of USA 2025.
The cope is American Exceptionalism, we're doing just fine even though we're fighting a unprofitable proxy-war and missed all those b2c investments to leech off humanity.
There's no desktop OS from Finland, that's a kernel and yes he's now American as you guys usually were better at finding ways to turn good into profit.
> The cope is American Exceptionalism, we're doing just fine even though we're fighting a unprofitable proxy-war and missed all those b2c investments to leech off humanity.
We are not doing just fine. We have low economic growth. We are unable to beat off Russia's attack on Ukraine without American help. Germany has crumbling infrastructure just as much or more than America. We have not contributed seriously to any important innovation wave since before... 2000? The invention of the PC?
Economic growth is a measure of how much goods and services are available to everyone. If that isn't improving, that means your quality of life is lower, ceteris paribus. It means you don't produce enough energy on your own are dependent on Russian gas. It means you don't have enough surplus to sustain a military.
I assumed the parent was referring to "GDP growth" which doesn't matter when inflation eats it all and new coins go to megacorps rather than back into society, European standards of living has been consistently improving, especially for the poorer nations.
I can't defend Germany for refusing nuclear in favor of Russian gas, but at the time it seemed to some like a good idea to strengthen relationships through trade and encourage democratization.
It's a damn shame that we're buying Russian gas, it's hilarious that I keep hearing about this from Americans but not Ukrainians.
I honestly don't understand that change, as most desktops are RAM limited as well, especially as Debian is regularly used for older machines, which aren't supported by Windows 11 anymore.
Is it common for scripts to download multiple gigabytes to /tmp?
I sometimes manually changed the /tmp to be in memory, or used /dev/shm which by default is in memory. Did not run into any problems just yet, but then again it's just a home server.
Not sure about scripts, but I download and store everything I know I'll only need until the next reboot in /tmp and naturally that tends to be quite a lot from time to time. That worked fine for decades, so I'm not sure what's the benefit if storing the contents of /tmp in memory instead.
