  • 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.


  • You can’t pretend an open port is closed, because an open port is really just a service that’s listening. You can’t pretend-close it and still have that service work. The only thing you can do is firewalling off the entire service, but presumably, any competent distro will firewall off all services by default and any service listening publicly is doing so for a good reason.

    I guess it comes down to whether they feel like it’s worth obfuscating port scan data. If you deploy that across all of your network then you make things just a little bit more annoying for attackers. It’s a tiny bit of obfuscation that doesn’t really matter, but I guess plenty of security teams need every win they can get, as management is always demanding that you do more even after you’ve done everything that’s actually useful.


  • 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…
