  • 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.

    Most distros use systemd and its logging solution: journald. You can use journalctl to read the logs around the time of the crash for e.g.:

    • journalctl -S -5m this shows the last 5 minutes. Use this when a game crashes but the system continues working and did not reboot.
    • journalctl -b -1 -S -10m this shows the last 10 minutes from the previous boot. Use this if the crash froze the whole system and rebooted.

    Look for red lines (errors) and what wrote them. AMD GPU faults usually have the ‘amdgpu’ mentioned, memory errors could appear as ‘protection fault’.

    With the currently available Android tablets the software really limits its uses. Many of the higher quality product focus too much on productivity without success. But this creeps up the prices so much that makes them hard to justify for entertainment.

    I think there are only a few use cases where tablets shine:

    • A small (and cheap) reader that’s a comfortable in one hand with a decent screen resolution. It works great as a big phone to enjoy reading comics, books, websites or browsing social media. The Tab S6 Lite 2022 is a solid 10" option and chinese brands offer 8" tabs like the Doogee T20 Mini. You won’t get long software support but the price makes it somewhat acceptable.
    • An Oled multimedia screen. These are great for all kinds of videos, movies and series. There are just a few options like the P11 Pro Gen2 that are affordable.

    Longer software support is only available from just Samsung or Google and I can’t justify the prices of those if a laptop can replace it. Here a Pixel Tablet or a Tab S9 costs the same as 13" laptop with oled screen (Zenbook S 13) with “unlimited” software support.

    I do own a T20 Mini and an old ThinkPad and I really like reading on the Android tablet even with the slow SoC and medicore screen, but bring a real laptop along for longer trips.

  • For the storage you have an additional option: converting a PCIe slot to M.2 Nvme is possible with a passive addin card. This way you could keep the current OS drive and add a 2TB m.2 instead of a SATA one. Since M.2s are quite cheap I went this route last year. Just be warned that secondary x16 slots are slower: it looks like 2.0 x4 for the b450-a pro max.
