    FSF is the exact opposite of "cutting edge".

    Like "super dull".

    Glad to know the FSF is continuing to be relevant! To vintage computing enthusiasts like myself, I mean.

    The ASUS KGPE-D16 is from the AMD Opteron 6000 series days and has DDR3-1600 memory support. Besides having the open-source firmware it's hard to argue in favor of it especially given the era of today's CPU security vulnerabilities and long outdated CPUs not seeing any microcode updates or any formal security guidance
    No not really. Actually, that's one benefit of the Fam 15h server chips from AMD - there are no unmitigated CPU security vulns that impact the Opteron 6000 series. None! The only vulns it's affected by are a couple of the Spectre variants, which are mitigated in the OS.

    Here's the output from the latest spectre-meltdown-checker.sh script on my Opteron 6386 server:

    * Affected by CVE-2017-5753 (Spectre Variant 1, bounds check bypass): YES
    * Affected by CVE-2017-5715 (Spectre Variant 2, branch target injection): YES
    * Affected by CVE-2017-5754 (Variant 3, Meltdown, rogue data cache load): NO
    * Affected by CVE-2018-3640 (Variant 3a, rogue system register read): NO
    * Affected by CVE-2018-3639 (Variant 4, speculative store bypass): YES
    * Affected by CVE-2018-3615 (Foreshadow (SGX), L1 terminal fault): NO
    * Affected by CVE-2018-3620 (Foreshadow-NG (OS), L1 terminal fault): NO
    * Affected by CVE-2018-3646 (Foreshadow-NG (VMM), L1 terminal fault): NO
    * Affected by CVE-2018-12126 (Fallout, microarchitectural store buffer data sampling (MSBDS)): NO
    * Affected by CVE-2018-12130 (ZombieLoad, microarchitectural fill buffer data sampling (MFBDS)): NO
    * Affected by CVE-2018-12127 (RIDL, microarchitectural load port data sampling (MLPDS)): NO
    * Affected by CVE-2019-11091 (RIDL, microarchitectural data sampling uncacheable memory (MDSUM)): NO
    * Affected by CVE-2019-11135 (ZombieLoad V2, TSX Asynchronous Abort (TAA)): NO
    * Affected by CVE-2018-12207 (No eXcuses, iTLB Multihit, machine check exception on page size changes (MCEPSC)): NO
    * Affected by CVE-2020-0543 (Special Register Buffer Data Sampling (SRBDS)): NO

    All those 'NO' line items mean the chip does not have that vuln. Intel chips of the same era would be all yes's. The only three 'yes' entries are for Spectre, and all three are mitigated in the Linux kernel:

    Code:
    spectre_v1 : Mitigation: usercopy/swapgs barriers and __user pointer sanitization
    spectre_v2 : Mitigation: Retpolines, IBPB: conditional, STIBP: disabled, RSB filling, PBRSB-eIBRS: Not affected
    ​spec_store_bypass : Mitigation: Speculative Store Bypass disabled
    Opteron, as old as it is now, is the most secure x86-64 microarch of the past decade. Of course if any new Opteron hardware vulns are discovered, it won't get a microcode update. But as of today, it's about as secure as you can get.

    These are elitist environmental talking points that have little or nothing to do with real environmental impact analysis - you have to consider the cost to the environment of digging up the rare earth metals and the cost to the environment of the manufacturing process for the more recent CPUs/systems. Or did you think these newer computers were harvested from seeds grown in greenhouses in a 100% carbon-neutral manner?

    The fact is, you cannot resolve "concern[s] about the environment/climate" through your purchasing of one manufactured item vs another. What you can do is live in tune with nature. Instead of sending another old gas-guzzling car to add to the toxic waste at a junkyard and replacing it with a new Tesla, you could just start walking or riding a bicycle that was manufactured decades ago. I do that about 6-9 months of the year - it's also exceptionally good for your health.

    I have friends who use the ASUS KGPE-D16 and who get a lot of work done with it. If you can end your addiction to binge-watching Netflix and binge-watching TikTok and 24/7 online gaming and just use the computer when you need to actually do something productive, then you would certainly not putting any strain on the grid by using it. Junking a useful and capable computer into a toxic landfill and replacing it with a new system with all its rare earth metal inputs and manufacturing energy inputs is problematic.

    If the thought of plugging an older computer into an electrical outlet horrifies your elitist sense of woke climate alarmism, you can move to the desert in New Mexico and build yourself an earthship to live in and cut yourself a vertical tin wind turbine for power. Voila - modern living without having to manufacture anything or use any power from the grid.
    Why can I vote up something only once?

    The FSF is a complete parody of itself at this point.

    Cool. And that's precisely why no one takes them seriously.

    Lol, they're offering the whole Trisquel sources of ~6 GiB for a stupid NIC with a classic PCI interface and something that looks like your run-of-the-mill RTL8139 chip, whose in-kernel driver code might be some KiBs.
    Indeed, this look dire. And yes, we need more good advocates for freedom drivers/firmware/hardware. But just recent Coreboot release looked to disappointing, no real boards supported, it has become a Google-only-thing.
