How do these federated forges deal with spam? If merge requests and issues are federated, does that mean that anybody running a radicle node (or interacting with one) can open issues or merge requests on all the repositories that you've made public? Or is there a whitelist (or something fancier?) to allow interaction only with specified nodes?

Okay, good to hear on both counts. Thanks!

Oddly specific question, but can anybody confirm whether the AX210 (no vPro) wifi works with the AMD motherboards? I've seen some pretty bad reports about the realtek chip they're defaulting to on the AMD systems, and I already have the AX210, so if I could just keep using it, that would be ideal.

Okay, good to know it's being considered. For a non-optimized diff then (zfs-diff, which just prints which files have changed, not what about them have changed), it would be the same approach? Scan all the metadata looking for keys with versions between the two snapshots, and print out the associated file names? Would that simple approach be likely to be faster than whatever rsync does to find updated files when doing a backup?

Speaking of snapshots, are you planning to have analogs to ZFS's send/recv and diff? I didn't see any mention of them on the snapshots page or the roadmap, but I could be looking in the wrong place. Already having reflink support is exciting though; a ZFS replacement that can also do reflinks would be amazing.

I've personally seen as low as 30ms, but also up to 60ms. I also have a bit of packet loss, but my dish is just sitting on the ground in my wooded back yard right now. Once the weather turns back towards just being cold, I'm going to move the dish to my roof and see if that helps the packet loss. Maybe being able to see more of the sky will help get a more consistent latency too, but I'd guess more satellites are really going to be the fix there.

A specific safety article was written up by tweag.io, who wrote a pretty slick set of java bindings. Managing resources between two garbage collectors (ghc and jvm) is error-prone, so they used linear types to help prevent a bunch of the things a person can easily mess up. Their article is pretty good: https://www.tweag.io/blog/2020-02-06-safe-inline-java/

I don't personally do this, but if you're taking scheduled snapshots of your ZFS filesystems, you could also have a scheduled job (say, nightly) that emails you a "zfs diff" [0] between the current snapshot and the one from 24 hours ago. It won't tell you that you've been hit by malware, but an unexpected spike in changes could be something worth investigating.

https://cloud.google.com/edge-tpu/ has a "Buy" button that leads to https://coral.ai/products/ . They appear to be available for purchase?

edit: reading more on the edge-tpu page, they definitely appear to be of limited use compared with the ones available to google's hosted plans.

Somewhat; if your system boots through EFI (as opposed to the ancient BIOS boot), then you can compile your kernel with the EFI_STUB option[0]. That kernel can be placed in EFI/Boot/bootx64.efi (or whatever you've configured your EFI to boot), and the EFI boot loader will run it without any other boot loader. IME, this goes very well with a built-in initramfs (INITRAMFS_SOURCE[1]), so you have a single-file kernel and ramfs that boots directly from EFI.

It's not much tinkering at all. Once you've installed powertop (probably just "dnf install powertop" or "apt install powertop", or whatever your favorite flavour is), you can just run "sudo powertop --auto-tune"[0]. If you do like to tinker, you could maybe write your own init script to run that on boot, but your distro probably included one already.

> That's as opposed to "validated" ECC support in, say, AMD's Threadripper platform. In that case, if a company builds and markets a motherboard as compatible with Threadripper, and it lacks ECC support, they can expect to receive a nasty letter from AMD's legal team.

Are you sure about that? I'm only asking because the System76 Threadripper Thelio[0] doesn't support ECC (according to the response I received from their support people). Their response was actually that "Threadripper and our motherboard do not offer ECC" (TR obviously does support it though), but is it the case that they're actually contractually obligated to support ECC?

OP is somewhat conflating two different things: non-strict function evaluation and lazy IO. With lazy IO, you can get, for example, a String from a file. That string is actually a lazily-constructed chain of Cons cells, so if you're into following linked lists and processing files one char at a time, then it's fun to use. The dangerous bit comes in when you close the file after evaluating its contents as a string:

    fd <- open "/some/path"
    s <- readContentsLazy fd
    close fd
    pure $ processString s

Now, processString is getting a string with the file's contents, right? Nope, you have a cons cell that probably contains the first character of the file, and maybe even a few more up to the first page that got read from disk, but eventually as you're processing that string, you'll hit a point where your pure string processing actually tries to do IO on the file that isn't open anymore, and your perfect sane and pure string processing code will throw an exception. So, that's gross.

That's a real issue that will hit beginners. There's been a lot of work done to make ergonomic and performant libraries that handle this without issues; I think that right now pipes[0] and conduit[1] are the big ones, but it's a space that people like to play with.

I've had a thought for a while, that if a cop can produce their body cam footage, then they were acting as a cop. If they cannot, then they were acting as a private citizen (and their actions must be judged as though any other private citizen had done them). It seems sufficient to me, but I'd love to hear peoples' ideas on how it would be abused. I'm guessing it falls apart somewhere around how evidence is judged to be admissible (cops actually have tighter rules than private citizens?), but I really don't know.

I believe you're thinking about their initial application. They've updated it [0] to an altitude of 550km, so atmospheric drag should still de-orbit broken satellites fairly promptly.

So, I think WireGuard can't, but it can be used as a part of the puzzle. I'm running a mesh using WG as the security layer, and then l2tp to provide a layer 2 on which to run batman-adv. I have a bunch of machines getting DHCP addresses from my home router that way, and (I assume) batman gives me good routing. Of course, cobbling together your own "secure" mesh probably isn't ideal, but it works surprisingly well.
