  • Windows prefers to deactivate or minimize the write cache on removable devices, most of the common Linux distros generally don’t make such changes. Microsoft has a very good reason for that default: not a lot of people actually use the “safely remove hardware” option and if the cache is enabled, using and waiting for that is a hard requirement for the data to have actually made its way onto the drive.



  • It’s not and I’m not sure how that article arrived at that conclusion. Their E2EE crypto is problematic homebrew crypto, but that’s very, very different from being closed. The whole desktop client including the implementation of that crypto is fully open source and lives right on GitHub. Plenty of people have independently reviewed it and came back with a very iffy impression of the whole thing.

    Really the only difference is that Telegram doesn’t publish their backend, but the one Signal publishes is missing a couple of bits related to their “spam filter”, which happens to take in the source & destination of messages and do anything it wants with them. That doesn’t matter for either platform’s E2EE properties in any case, since distrusting the server is the whole point of E2EE.


  • Moderation is handled by each instance’s version of that community separately.

    Reddit/Lemmy/etc communities differ from something like Tumblr/Cohost by also having per-community rules, and nobody has the time to moderate hundreds of communities according to their per-community rules.

    It’s relatively easy to keep an instance free of spam/overly blatant hate/etc, since that is a fairly common set of rules. But it’s much harder to keep a “world news” style community being overran with US-centric posts, or a discussion community on a specific subject from being filled to the brim with memes, or posts that are only very vaguely adjacent. Without centralized per-community moderators, it would fall on general instance moderation to make decisions about whether a post about an Undertale hack fits in the Undertale community. That’s probably going to go wrong more often than not.

    You can have a website that is only moderated according to global rules with tags being a free-for-all, but you fundamentally end up building something along the lines of Tumblr or Cohost, which attracts a different audience, including those that know how to rules lawyer their way in such an environment; tagging 20 mediocre photos a day with #photography instead of just a good one, for example. With the end of Cohost approaching, I wouldn’t be surprised if some tried to build that kinda thing, but it’d likely end up having a very different vibe.



  • Most paid certs aren’t worth much anyway. Payment and delivery info for DV certs isn’t validated by anyone, it’s literally the same concept as Let’s Encrypt. OV and EV are the only ones that theoretically have any value, but nobody is using those ever since they got rid of the URL bar labeling; even Amazon is on DV nowadays.


  • The main reason many sub-communities are stuck on Telegram (and Discord) are the public group chat/broadcast channel related features. Signal still has a 1000 member group size limit, which is more than enough for a “group DM” but mostly useless for groups with publicly posted invite links. Those same groups would also much rather have functional scrollback/search on join instead of encryption.


  • Gonna add a dissenting “maybe but not really”. YT is really aggressive on this kinda stuff lately and the situation is changing month by month. YT has multiple ways of flagging your IP as potentially problematic and as soon as you get flagged you’re going to end up having to run quite an annoying mess of scripts that may or may not last in the long term. There’s some instructions in a stickied issue on the Invidious repo.


  • It’s absolutely not the case that nobody was thinking about computer power use. The Energy Star program had been around for around 15 years at that point and even had an EU-US agreement, and that was sitting alongside the EU’s own energy program. Getting an 80Plus-certified power supply was already common advice to anyone custom-building a PC which was by far the primary group of users doing Bitcoin mining before it had any kind of mainstream attention. And the original Bitcoin PDF includes the phrase “In our case, it is CPU time and electricity that is expended.”, despite not going in-depth (it doesn’t go in-depth on anything).

    The late 00s weren’t the late 90s where the most common OS in use did not support CPU idle without third party tooling hacking it in.



  • Personally, I do believe that rootless Docker/Podman have a strong enough security boundary for personal/individual self-hosting where you have decent trust in the software you’re running. Linux privilege escalation and container escape exploits fetch decent amounts of money on the exploit market, and nobody’s gonna waste them on some people running software ending in *arr when Zerodium will pay five figures for a local privilege escalation or container escape. If you’re running a business or you might be targeted for whatever reason (journalist or whatever) then that doesn’t apply.

    If you want more security, there are container runtimes that do cooler security stuff under the hood, like Firecracker/Kata Containers implementing a managed VM, or Google’s gVisor which very strongly intercepts kernel syscalls and essentially reimplements Linux in userspace. Those are used by AWS and Google Cloud respectively. You can integrate those into Docker, though not all networking/etc options are supported.




  • For that card, you probably have to set the radeon.si_support=0 amdgpu.si_support=1 kernel options to allow amdgpu to work. I don’t have a TrueNAS system laying around so I don’t know what the idiomatic way to change them is.

    Using amdgpu on that card has been considered experimental ever since it was added like 6 years ago, and nobody has invested any real efforts to stabilize it. It’s entirely possible that amdgpu on that card is simply never gonna work. But yeah I think the radeon driver isn’t really fully functional anymore either, so I guess it’s worth a shot…


  • All GPUs released since they came out with the RTX 2000+ line are supported and all new GPUs will most likely have support, especially with this announcement saying they’re committed to it. There’s a support list on their GitHub and it includes all the weird little things you’d be worried about. Even silly little laptop chips like the new RTX 500 are on it.

    I think the only reason they limited GPU support is because the older ones physically don’t have the hardware for this approach; they switched to their newer RISC-V “GSP” processors with the RTX line. In the new open module, all of their proprietary “secret sauce” was shoved off to firmware running on that new GSP. Previously, their proprietary kernel module loaded all of that same secret sauce as a gigantic obfuscated blob running on your normal CPU instead. The Windows side of their driver has also been moving towards using the GSP, they even advertised it boosts performance or whatever, and I can believe it.

    That said, with this new stuff, the official Nvidia userland portions providing Vulkan/OpenGL/CUDA support and the like are still proprietary. It’s still worse than AMD in that regard. But at least it’s possible to replace those bits, and Mesa/NVK are working on getting Vulkan up and running (with NVK supposedly getting pretty damn good, and Mesa’s OpenGL-on-Vulkan is pretty good too so that’s free).
