  • Grid-Scale Bubble Batteries Will Soon Be Everywhere

    Jump

  • They are talking hectares in this and it looks like the power density is below that of batteries, but its also cheaper per MWh.

    A 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.

  • Maybe we don't need a server

    Jump

  • 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.

  • Self-Hosting on Gamers Nexus | what computer is that?

    Jump

  • 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!

  • What's the best chat to self host?

    Jump

  • 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.

  • 96,000 UK Police Bodycam Videos Lost After Data Transfer Mishap

    Jump

  • Someone was reviewing some footage and decided to hide the deletion in amongst lots of other benign videos. They seem to always loose the critical videos showing police brutality don't they!?

  • EU age verification app to ban any Android system not licensed by Google

    Jump

  • Its not the populace, our politicians just like in the US have gone rogue. People are voting for the nutters due to anti immigration propaganda and so increasingly getting far right. Its happening across the entire western world and its bad news for everyone.

  • Very large amounts of gaming gpus vs AI gpus

    Jump

  • Initially a lot of the AI was getting trained on lower class GPUs and none of these AI special cards/blades existed. The problem is that the problems are quite large and hence require a lot of VRAM to work on or you split it and pay enormous latency penalties going across the network. Putting it all into one giant package costs a lot more but it also performs a lot better, because AI is not an embarrassingly parallel problem that can be easily split across many GPUs without penalty. So the goal is often to reduce the number of GPUs you need to get a result quickly enough and it brings its own set of problems of power density in server racks.

  • Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition'

    Jump

  • Grid forming will just mean the keep running the house when the power goes off, it's not safe for them to be pushing power when it's disappeared, that has been set by regulation in many countries.

  • NAS Power Consumption

    Jump

  • I use a 5600g on b450 ITX board and 4x 8GB Seagate drives and see about 35W idle and about 40W average. It used to be 45W because I was forced to use a GPU in addition to a 3600 to boot (even though its headless, just a bad bios setup that I can't fix) and getting a CPU with graphics dropped my idle consumption quite a bit. I suspect the extra wattage for your machine is probably the bigger motherboard and the less efficient CPU.

    It is possible to get the machine part down into single digits wattage and then about 5W a drive is the floor without spinning them down, so the minimum you could likely see with a much less powerful CPU is about 30-35W.

  • Google confirms more ads on your paid YouTube Premium Lite soon

    Jump

  • There is no end to the greed of those with millions and especially billions and they aren't content to just keep running a profitable business, they have to get all the money.

    This is just the history of humanity and finances forever, the one saving grace in all this is every big business gets complacent in its money making and seeks ever increasing profit (and becomes management heavy) until a young upstart finds a way to do it a lot better and cheaper and disrupts the market. Google has become the big lumbering unable to change organisation seeking maximum profit now, its become IBM.

  • FreshRSS weirdness

    Jump

  • Make sure none of the exceptions are ticked and the Minimum number of articles to keep per feed is also 25 or below. Then its up to the cron when that runs so you might have to manually purge it and optimise the database to see what it will actually keep.

    I can't say I have ever worried about it, been running FreshRSS for years and it seems to keep its database size in check fairly well and the defaults have worked fine for me and it rarely gets above 100MB. So I know it "loosely" works in that old articles are absolutely getting purged in time but have no idea how strictly it follows these rules.

  • A UK government trial with 20K+ civil servants using Microsoft's Copilot AI for three months found a 26 minute average daily time saving, or two weeks per year

    Jump

  • the lack of control group undergoing the same monitoring means there is a high chance of bias.

    I would also want to see secondary measures such as the amount of queries people did and what they actually used it for. Might be worth tracking over time to see if there is an increase or decrease in use. These sort of secondary measures give some confidence that it is useful and its continuing to be so and its not just people behave differently when watched.

  • Stack Overflow seeks rebrand as traffic continues to plummet – which is bad news for developers

    Jump

  • Even if your in and have a history of good questions and responses it is still ridiculously hard to get a question accepted. Stackoverflow is dying due to its own choices and its driven many people away from it. They caused their own peak in 2014 and its amazing it took this long to decline.

  • Judge Rules Apple Top Executive Alex Roman Lied Under Oath, Makes Criminal Contempt Referral

    Jump

  • After he acquired it all and spent decades doing illegal stuff for which Microsoft received extensive anti trust fines. Lets not kid ourselves here is trying to redeem himself for his prior billionaire behaviour and it often comes off more as "greenwashing" than actually helping people.

  • Judge Rules Apple Top Executive Alex Roman Lied Under Oath, Makes Criminal Contempt Referral

    Jump

  • Wealth based fines would be extremely based. Most people would pay nothing and the wealthy would be paying a heck of a lot more. Which is why it will never happen its all about punishing the workers.

  • Selfhosting static site behind two routers?

    Jump

  • The DMZ for the ISPs router forward to the second router, then everything that hits your outside IP will be forwarded to router 2. Then on Router 2 you open the ports for your service and forward to the internal machine. That should all work fine.

  • What CI/CD tools are you guys using? I have Forgejo but I need a simple way of running automation.

    Jump

  • Its quite complicated to setup as well, just went through the instructions and its a long way from just add to docker and run unfortunately. Would be nice to be able to just get a runner in the same or different docker and it just works easily without a lot of manual setup in Linux of directories and users and pipes etc.

  • An alternative to Contabo (VPS provider)

    Jump

  • I did the same move from contabo to Netcup. Contabo I had all sorts of weird bandwidth limiting problems that I couldn't explain and which the continued to deny they were throttling. Netcup worked perfectly.

  • So many of the GPUs have been crippled for the purposes of gaming and there is zero incentive for Nvidia to produce drivers for those cards to do anything else. Alas they will just end up in landfill.
