  • Navigate to a problematic movie or episode -> 3 dots -> Get info -> right column -> Color space

    Usually SDR is bt709 and HDR is bt2020. In older codecs (h264) 10 or 12 bit color depth can also cause issues.

    I’m not sure how tone mapping works on plex since I don’t have a pass but with Jellyfin you need to setup OpenCL which is run on the GPU so your guess that a hardware change can break it is plausible.







  • The FS feature is great, it’s just cumbersome to use without a tool.

    Snapper works well for a local backup like history both against botched updates and accidental deletion, but eats up the free space with the default settings.

    Timeshift is an easy to use GUI but doesn’t support non-default partitions.

    Also the quota support had a nasty side effect: freezing the whole system on snapshot deletion.


  • It’s hard to live up to expectations after Frieren but here are some that were memorable for me:

    • Fate Zero - it’s a battle royal with magic, the story isn’t the focus but the characters and fights are great
    • Spice and Wolf - this is about a merchant’s journey with an unusual companion (there is a new (re)adaptation coming next season, but the old version is also quite good)
    • A Certain Scientific Railgun - a sci-fi city and it’s secrets, I think it does well in the would building

  • I think calling it a “cache” is not precise. The primary function of the DRAM is to hold the dictionary for translating logical addresses (e.g. sectors) from the OS to the physical addresses (which NAND chip, which bank etc.). This indirection is needed for the controller to do wear leveling without corrupting the filesystem.

    On a SATA SSD without DRAM each read IO could mean 2 actual reads: first the dictionary to find the data and than the actual data being read. As you said HBM helps by eliminating this extra read.

    The read and write caching is just a use of the remaining DRAM capacity. Since modern Operating Systems use the general RAM for the same function it is usually just a small increase to the throughput.




  • If you are looking to reduce the build’s cost consider a cheaper motherboard or a used GPU. The Asrock B650M-HDV/M.2 is the lowest you should go if it has all the connectors you need. As for buying used video card it’s always a bit of risk, but as the most expensive component you could save the most on that. Since all AM5 CPUs have an integrated GPU you could build without the dedicated GPU first.









  • Thanks for the links! I updated my config from z3fold to zsmalloc and adjusted the vm.page-cluster to test these out.

    Reading a bit more, I think when using large max_pool_percent (>30) with Zswap the two solutions are more similar than not. A crucial difference is what use-case is more acceptable since Zswap can cause unresponsiveness (and potential lockup) under high memory pressure. While Zram could result in an OOM crash in a similar worst-case scenario.
