  • 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.

  • Linux has over 6% of the desktop market? Yes, you read that right - here's how

    Jump

  • Most technology adoption follows an S curve, it can often take a long time to start to get going. Linux has gradually and steadily been improving especially for games and other desktop uses while at the same time Microsoft has been making Windows worse. I feel more that this is Microsoft's fault, they have abandoned the development of desktop Windows and the advancement of support for modern processor designs and gaming hardware. This has for the first time has let Linux catch up and in many cases exceed Windows capabilities on especially gaming which has always been a stubborn issue. Its still a problem especially in hardware support for VR and other peripherals but its the sort of thing that might sort itself out once the user base grows and companies start producing software for Linux instead.

    It might not be enough, but the switching off Windows 10 is causing a change which Microsoft might really regret in a few years.

  • 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.

  • Must fight temptation to buy an overpriced raspberry pi

    Jump

  • It's low power that is still making arm small computers popular. It's impossible to get a pc down into the 2-5 Watt power consumption range and over time it's the electrical costs that add up. I would suggest the RPI5 is the thing to get because it's expensive for what it is and more performance is available from other options supported by armbian.

  • 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.

  • 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.

  • Shredding my SSDs (NVMe) under linux?

    Jump

  • Everyone has given Linux answers, its also worth knowing quite a lot of UEFI's contain the ability to secure erase as well. There are a number of USB bootable disk management tools that can do secure erase as well.

  • (James Hoffman's) AeroPress Premium Review

    Jump

  • We really could do with a proper way to investigate the microplastic impact of the normal Aeropress. I know testing in microwaves with plastic containers showed ridiculously higher plastic count compared to just cold storage and this is a big part of the problem with the Aeropress, it gets hot and that frees a lot more plastic in other tests. Would be nice to know how much of my brain is turned to plastic because of Aeropress brews over the years!

  • Nvidia reportedly raises GPU prices by 10-15% as manufacturing costs surge — tariffs and TSMC price hikes filter down to retailers

    Jump

  • When the AI market crashes its going to be brutal.

  • 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.

  • EA's Skate. devs confirm the game will be always-online with no offline mode

    Jump

  • So people are paying full price to buy a rental that will be taken away in the future whenever EA decides its not worth running the servers any more.

  • rss feeds

    Jump

  • 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.

  • As games become ever more multithreaded, Intel's hybrid CPU design might start to lag behind AMD's simpler but more effective architecture

    Jump

  • Not necessarily. Ignore chiplets because that is mostly about yield and price and look at what happens when we go very threaded. Smaller cores with less clockspeed take up less space and less power and are more efficient with both which leads to more total compute performance in a given space and power budget. The ideal CPU in a highly multithreaded environment has a small number of P cores that matches the number of single threaded combining threads and as many E cores as possible due to Amadhl's law. The single threaded part comes to dominate given enough multithreading and all algorithms have some amount of single threaded accumulation of results.

    AMD is working with the same limitations and bigger cores with more clockspeed will always have less total cores and achieve less total compute performance in that space. The single threaded component will dominate at high core counts so the answer is not all P cores and not all E cores and AMDs cores should be considered P cores. The ideal number of P cores is definitely more than 1 because the GPU requires one of those high performance threads and the game will need at least one depending on how many different sets of parallel tasks it is running.

    But the problem is this theoretical future is a bit far off because we can clearly do today’s games with 6 cores quite happily and most don't really utilise 6 cores well. They tend to prefer all high performance cores, no one is yet at the stage of dealing with the added complexity of heterogenous CPU core performance and its why both AMD and Intel have special scheluders to improve game utilisation a bit better, this approach of differing core performance first a little and then with E cores quite a lot is too new since big AAA games are in development for many years. So while its likely the future gains from silicon slow further, necessitating optimising the compute density and balance of cores, its unclear when Intel's strategy will pay off in games, it pays off in some productivity applications but not games yet.

    I am certain this approach and further iterations of it with multiple different levels and even instruction sets are quite likely the future of computing, so far its been critical for the GPUs success, its really unclear when that likely future will happen. It definitely doesn't make sense now or the near future so buying a current Intel CPU for games makes no sense.

  • 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.

  • Fewer beans = great coffee if you get the pour height right

    Jump

  • Its going to have a tendency towards bitterness.

  • Seagate's fraudulent hard drives scandal deepens as clues point at Chinese Chia mining farms

    Jump

  • The problem is the information asymmetry, there is always another person for a fraudulent company to exploit due to a dysfunctionally expensive court system. Its why we need market level regulations and public institutions that recover peoples money and fine the organisations for their breaches. This sort of thing works a lot better in the EU than in the US due to the sales laws, the ability to return within 2 weeks, default warranty on goods out to 12 months and expectations of goods to be as advertised forced onto the retailers. They work, they need more enforcement from regulatory bodies but retailers do follow them for the most part and quickly change tune when you go to take legal action when they don't because courts know these laws inside and out.

  • NVIDIA's tight margins on GeForce RTX 50 series: pressure on AIBs as 'MSRP feels like charity'

    Jump

  • That sure is some bad framing. Nvidia is charging too much to squeeze out the AIBs or they all just want too much profit for their part in this. Either way its not that the MSRP is charity(!) its just high prices.
