  • This is a good way to do it.

    I went one smaller with the Node 304 which only can do 4 HDDs with a GPU inserted. Going used for consumer desktop CPU is the most powerful play for the money I think.

    This is a good path forward OP for a pretty powerful server

    • Node 804
    • Used AM4 motherboard ( microatx B550) (can be around 150€)
    • used 5700X or similar (seen as low as 100€)
    • new 500W power supply
    • 32GB DDR4 3200 ram in 16GB sticks
    • WD red plus 10TB helium filled for balance of noise and performance and price. My 10TB drives are as quiet as my 4TB. My scheme is ZFS mirror of 4TB (2 drives) for important docs, and 10TB drives for non critical data. Drives are by far the most expensive unless you get good second hand drives
    • if you want to do Jellyfin media server, pick up an arc A310

  • In the professional space:

    Add Altium, KNX, pspice, LTSpice (luckily works in wine), and for us electronics/electric guys lol.

    Linux is a 3rd class citizen in ANSYS simulation tools. Slow updates, old UI, etc… On Linux. Pretty much only used as a simulation node for kicking on sims from windows.

    Pretty much all architecture software

    Many ERP systems desktop apps

    Not to mention a lot of companies use active directory for access control + sharepoint

    Web apps suck, but have been very helpful in Linux compatibility in the enterprise space since the devs only have to care about 1 set of production builds.

    At my work, software guys and mechatronics PLC focused guys get away with Ubuntu (saleae is great), but for electronics and mechanicals it is not even worth it to dual boot.


  • I want a new, modern Battle for Middle Earth 2 with better balance, modern graphics, and maybe different modes like quick vs longer form games. Definitely some reform like making it more difficult to build walls, but the walls stand up better to infantry and you really need siege engines.

    The game was not balanced competitively (men so OP) but holy damn the battles felt epic and building your own forts and castles to defend was amazing.




  • You said it right there in your comment.

    Sleep mode, (and other effectively off modes) where it is functionally useless, it can do.

    MSP430 can do 140uA/MHz. That is ~7 times the power that this application supplies, and that is not counting any single other chip quiescent current or chip that actively provides useful data. You would have to have a battery anyway or a big cap to provide the needed current for on-states. Or you could run it extremely low frequencies like you said, but those tend to not scale linearly at all with per MHz power ratings. Quiescent currents tend to catch up fast at that scale. I would be extremely doubtful that 150kHz would scale perfectly and wouldn’t have already exponentially decayed to around its lowest possible on-state consumption for the chip. I would definitely have to see tests on that.

    The smallest of batteries like the VARTA tiny cells in TWS’s are infinitely more useful and practical and it would take this application months to fill a single cell, discounting all losses.


  • It is the Mac of network hardware in my corporate - entered experience.

    It is aesthetic hardware, marketing, and everything software related looks polished on the surface, but is buggy (particularly their access which is the worst thing to be buggy) with the least possible configurability, completely obscured debugging resources, and proprietary ways to make you reliant on their support services.

    That being said, I am still using them because I got a 30€ UAP-AC-SHD from my company’s old stock when we switched to Cisco hardware. And their cloud gateway ultra is a good value. My whole house setup with prosumer hardware will be 140€ and where my internet comes in is the worst place in the house to put a wireless router.


  • I don’t think people realize how extremely little 50uW is.

    For a standard 3.3V microcontroller assuming a 95% efficient voltage regulator will be a current of 14.4uA. Just having the HSI master clock enabled on one of the low power STML0 chips is 15uA. This will literally only the clock. That is 0 sensors, 0 communication, 0 IO, nothing useful at all. For reference, reading SPO2 with a very efficient maxm86161 takes 10uA by itself in ultra low power mode with low accuracy and not counting the max leakage current of 1uA. For full operation, you need about 1000x-10000x that amount for short bursts.

    “Oh but it can cHaRgE tHe BaTtErY”

    Let’s say the device has a standard 100mAh battery (apple watch had a 228mAh or more). At 100% efficiency with absolutely not one millijoule being used by any other electronics (which would never ever happen, it would at the very least need a boost converter), it would take around 277 days to charge up that tiny tiny battery.

    Let’s take another example of an even smaller battery. To charge one side of the airpods 3rd gen (0.133Wh battery), it would take 110 days per ear

    This is one of those free “energy harvesting” fad BS based in nothing but wishing and marketing. It is an interesting learning project for wireless antenna beginners, but that is the extent.


  • While true, in order to get Linux mobile more mainstream, you have to have great google compatibility just because of the sheer volume of people that have to use google calendar for sync with family and friends and/or have gmail as a primary email. That’s just a shitty fact of life. Baby steps.

    However, indeed you are completely right that at the current time there are probably a very low amount of people wanting to use it right now that are completely reliant on google.


  • “Critical” as in not really needed.

    It is very bugged and constantly runs even if it isn’t doing anything. It will also max out your disk IO for hours at a time with an HDD for larger game storage.

    I have had it off for 1.5 years across 3 OS installs and have never had a problem with stuttering or shader related problems in that time. It is really not needed anymore for 95% of games since the Linux async solutions were merged.

    Maybe if one uses severely out of date kernels it is critical




  • That is a different usecase though. That is simply syncing local musical with a server.

    I do that too because i have an SD card. Just use Syncthing for that. Much faster and less hassle. You can use any music player on your phone that you want, not just one that works with jellyfin.

    If you aren’t streaming music in real time for the majority of time, then do a phone sync, not a streaming server.






  • Their entire list is odd choices except for the top 10 (even persona 5 is iffy as top 10 of all time)

    They favor shooters and then place a game that had lost most of its audience in under a year as the best shooter other than doom 1 of all time.

    I love helldivers, but it is a very niche game in comparison to so many others, even those on the list.

    Not to mention KOTOR and DA:O as 94 and 95. Also prey is an extremely weird choice…

    Kopia backup to secondary HDD

    • Pictures (phone photos backed up to my server via immich)
    • workspace (git repos, ECAD, MCAD, firmware, etc…)
    • qmk layout
    • Documents
    • vim folder with bundles
    • ebooks

    KDE vaults stores on secondary HDD

    Soon I will set up kopia to also back up every via SSH to my server and then small size essentials and important docs via google drive

    I need to set server cloud backups too, but haven’t had the time…
