What is your experience with btrfs snapshots?
  • 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.

  • Anime newbie looking for suggestions
  • 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
  • In what cases is a DRAM-less SSD good enough?
  • 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.

  • First build in a hot minute, any suggestions?
  • if the integrated one is good enough for gaming

    No, the iGPU is only meant for testing and basic desktop usage like video playback on the 7000 series. There are 8000G series with better integrated graphics but even those are much weaker than any dedicated GPU.

  • Upgrading my Gaming PC
  • Could you tell us more specifically what do you want to use/play on this PC? (e.g browsing or productivity apps, or old games or the latest AAA titles)

    A maximum budget would be very helpful.

  • First build in a hot minute, any suggestions?
  • 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.

  • An Interview with Pat Gelsinger - More Than Moore

    Video version: https://youtu.be/0PrmrMQ9gJU

    In February 2024, Intel held its first Intel Foundry Direct Connect event. [...] The tone of the event was one of success – Intel Foundry (IF) is set to be a semi-autonomous body of Intel that aggressively fights for business, whether Internal or External, without playing favorites.

    [...]

    Ian: It’s been said in the past that Intel bets the whole company on the next process node, is that still true?

    Pat: I’ve bet the whole company on 18A. We have committed products to this - it is the culmination of our 5 nodes in 4 years. So bringing that across the line, in that sense yes - I’ve bet the whole company on making this successful.

    NVIDIA GH200 CPU Performance Benchmarks Against AMD EPYC Zen 4 & Intel Xeon Emerald Rapids Review

    Here are some initial benchmarks of the Grace CPU performance while the Hopper GPU benchmarks will be coming in a follow-up article.

    NVIDIA's GH200 combines the 72-core Grace CPU with H100 Tensor Core GPU and support for up to 480GB of LPDDR5 memory and 96GB of HBM3 or 144GB of HBM3e memory. The Grace CPU employs Arm Neoverse-V2 cores with 1MB of L2 cache per core and 117MB of L3 cache.

    On a geo mean basis across all the benchmarks conducted, the GH200 Grace CPU performance nearly matched the Intel Xeon Platinum 8592+ Emerald Rapids processor. The Arm Neoverse-V2 based Grace CPU tended to be much faster than the 128-core Ampere Altra Max AArch64 server.

    Overall the NVIDIA GH200 CPU benchmarking was quite fascinating to see its early potential. There still are some workloads not too well optimized for AArch64 and in some cases the higher core counts and dual socket configurations available with Intel Xeon Emerald Rapids and AMD EPYC Genoa(X) / Bergamo could drive the results much higher.

    What would you change about your favorite Linux distribution?
  • 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.

  • Steam Next Fest is currently ongoing - which demos did you like/dislike?
  • Stormgate

    It's like 90% StarCraft 2 and 10% Warcraft 3. The competitive RTS part is promising but it didn't show me anything new. Depending on the lore and campaign it may get more interesting, so far it's neutral.

    Millennia

    It starts very similarly to Civ 6 with even more kinds of resources. The current version of the UI seemed confusing and the poor performance (on linux) stopped me from finishing the demo.

  • Amazon finds $1B jackpot in its 100 million+ IPv4 address stockpile | The tech giant has cited ballooning costs associated with IPv4 addresses
  • Even tough IPv6 is technically superior to IPv4 for the network operator it doesn't have clear benefits for home users.

    Having global addresses instead of NAT means less control over your LAN and these unique public addresses can track users more accurately.

  • What would you change about your favorite Linux distribution?
  • Btrfs with compression enabled and subvolumes set.

    And enable/automate maintenance services for BTRFS. For example: balace should be run on heavily used system disks or scrub could help detect errors even on single disks.

    ZRAM (With proper sysctl.conf like PopOS does).

    Could you explain the preference of ZRAM over ZSWAP? I thought the latter was the more advanced and better performing solution. Is there some magic in Pop's config?

  • AMD GPUs are cursed for me
  • Happy to help! Tough you are right, this is a rather generic error that doesn't help much just confirms that the GPU is the issue.

    At this point it could be a driver issue since there are similar open bug reports. A hardware problem is still possible since you previously said that it's unstable on windows too, and power related issues can also lead to this error message.

  • AMD GPUs are cursed for me
  • 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'.

  • AMD GPUs are cursed for me
  • Did you check the system logs to see what caused it?

    Many things can result in seemingliy random crashes. Any overclock (including XMP and Expo) or undervolt or even a bios version can be problematic.

    I would check first if it's stable on windows.

  • Android Tablets
  • 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.

  • Upgrade my 3 years old build
  • 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.

  • AMD EPYC Bergamo is a Fantastically Fresh Take on Cloud Native Compute

    While today we have both the AMD EPYC “Genoa-X” and “Bergamo” launches, Bergamo is clearly the more impactful of the two. That is a lot to say given we know that Microsoft Azure is very fond of Milan-X and Genoa-X. Let us put together a few key points:

    • The primary change for Zen 4c cores from Zen 4 is a halving of L3 cache.
    • The AMD EPYC 9754 is showing performance ~3x a 128-core Arm competitor at 1.5x the power.
    • An AMD EPYC 9754 is often twice the performance of 2019’s AMD EPYC 7002 “Rome” 64-core parts.
    • On most non-HPC-focused workloads, expect the AMD EPYC 9754 to be 15-20% faster than the AMD EPYC 9654. That is not a straight 33% as we would expect due to the core count increase, but AMD is getting scaling from the increased core count even with a drastically reduced L3 cache size.
    • AMD seems to have figured out an elegant way to reduce turbo clock jitter, especially at maximum load. That helps a lot with SLA on a loaded system.
    • Cloud-native processors will make up a huge segment of the market.
