They are talking hectares in this and it looks like the power density is below that of batteries, but its also cheaper per MWh.
I home long term battery makes a lot of sense, I have thought for a while something that goes from water and the air into methane or even liquid fuel would be highly beneficial as it could run from a generators through the winter and act for long term storage without requiring a turbine.
The only detail really is that at least 2 of the N machines you are using have to be on at the time so where ever a change was made is synced to another machine that is on and this continues so that you never end up booting a machine to use when nothing else with the latest files is available. This is where having a centralised low power machine is valuable and saves having a desktop or a laptop on when it doesn't need to be.
I really wish the desktop version of the world had not become so marginalised as local programs are considerably better to use than websites, they are so much quicker, accessible and easier to use.
They haven't completed their genocide yet, its going to continue until every last Palestinian is dead.
The outbreaks started under Biden. Vaccination and countering viral spread in general has been undermined by successive governments around the globe to get people back to work despite Covid still causing damage to a lot of people, including deaths, and the main causality has been public health.
This is where this all needs to go, swappable standard batteries like the 18650s being used and recharged in the device and replaced when the inevitable happens and they stop storing much charge. Batteries are consumable currently and devices without swappable ones are designed to fail within a few years.
The disaster is definitely going to be the thing that happens, because we have failed to act sufficiently for 50 years. There is no interest in most countries to do what is necessary at this point. Disaster is coming and sooner because climate change is accelerating every year.
I use a ZeroWater filter to get down to 0 Total Dissolved Solids and then third wave packets to reintroduce good minerals for coffee. Its still the case for me that this is cheaper than trying to buy distilled water or using distillation. Reverse osmosis is probably cheaper overall but a lot more initial outlay and it depends on how much water you need.
Brita and other similar small filters do a poor job of removing total dissolved solids (for me its the difference between 260 and 245 which is almost none removed) so they don't change the situation for coffee extraction all that much
On the one hand they were talking selfhosting and then they pull out multiple $10s thousands rack servers. People don't need a data centre at home to sync some files, pictures, email and play some media!
The primary smart parameters are passing but its a bit concerning that such a young drive is showing read error count, that isn't a good sign even if its within the makers tolerance. What failed was just the long test you requested.
Its not uncommon for drives to fail in weird ways and the smart shows as fine. When you come across problems like a long test failing or occasional checksum problems on your raid array or a read error its a better indicator that something is wrong. Presumably something made you think you better run a long test, and then it failed. I would say Contact reseller for warranty replacement you have enough to go on showing there is something going wrong on the drive, long tests should not be failing on a healthy device.
Every one always says XMPP and there were a lot of recommendations for ejabberd. I tried this recently and it was a total disaster, I do not have a working chat server. If I followed the docker instructions the server would just crash with no details of what went wrong. Where it should have been creating a default server config file it was instead creating a directory with the wrong permissions then promptly crashing. I tried following their documentation but after about 6 hours of messing about and adding more and more I still couldn't get a client to login to it. I have no idea how to make this work.
So whatever the solution ultimately is I can't recommend Ejabberd.
They aren't giving much information about these mini data centres. Basically it sounds like "Bitcoin farms" aka as AI training installed into peoples homes and they are using the heat from it to heat their homes. Its probably a better deal than most heating systems, they pay for their electricity use and connectivity and I get a low flat rate charge for heating.
The potential problem here is that the mouse model is based on the Amyloid theory of the disease, which this year was largely determined to be wrong after a series of major frauds were found in the research implicating Amyloid. This drug might still work since it seems to act on other aspects of the condition in the bloodwork but there is every chance this doesn't work in practice.
