I'm trying to look into that too. I think there's some configuration settings I can check and change there that may let me do that. Unbound is a DNS server that runs on anything, you can run to manage all this poo poo on your LAN, https://wiki.archlinux.org/title/Unbound I use pfsense for my router which comes with it integrated so I don't have as much experience running it on an ad-hoc server but depending on router make you might be able to tell your router which DNS servers to use, then when devices request DHCP it should hint at the DNS server too, which you point to your local unbound server, and then unbound resolves everything locally or forwards it upstream if its not local. If you can't configure it on your router youd just have to tell all your devices to use unbound manually, so 192.168.1.2 or whatever instead of 8.8.8.8. This is also how pi-hole works (idk if its using unbound behind the scenes), I use pfblocker-ng as an alternative to pi-hole so again not 100% sure just know its similar

By default pihole does not use unbound, though you can point it to an internal unbound server for dns resolution. https://docs.pi-hole.net/guides/dns/unbound/ or via container: https://github.com/chriscrowe/docker-pihole-unbound quadlet version for podman (needs to be run rootful) https://github.com/Nitrousoxide/appstore/tree/main/quadlet/pihole-unbound Nitrousoxide fucked around with this message at 20:33 on Oct 31, 2023 |

I love unbound. I use it to manage everything on my home network. Quick and easy flat-file configuration for all the basic stuff I do, and plenty of configurability for more advanced needs.

Subjunctive posted:isn’t that the rust thing linked above? It's "xrandr for gnome-mutter", it doesn't work on other DEs. So not the theoretical "xrandr for all wayland compositors" which might appease mystes's desire for a standard. ExcessBLarg! posted:Stuff like xrandr is most useful for desktop troubleshooting (which probably greater appeals to folks running sway, labwc, or something not kwin and mutter) and scripting in, say, a kiosk environment. Regarding the latter, if you're building a kiosk system then X11 is still plenty viable as the main security benefits of wayland are moot if you're primarily running a single application anyways. Yeah I guess a big source of the people who might hack together more commandline tools are still on X11.

How is bcachefs's implementation of tiered storage, disk groups, in practice? https://www.patreon.com/posts/tiering-is-dead-17110871 Is it reasonably performant and easy to use? Edit: I was looking at some guides to bcachefs and was a bit confused to see that rebalance and scrub aren't yet implemented. I haven't been following development too closely, but I would have expected one of the two to be implemented in the last 5 years. waffle iron fucked around with this message at 16:52 on Nov 1, 2023 |

Twerk from Home posted:I'd like to hear more about some of these, as someone approaching the first ever version upgrade of a several petabyte vanilla Ceph setup. The one I set up is now somewhere about 60PB, I think. Cephfs has been remarkably stable with current versions of ceph. But it was remarkably not stable 6 years ago when we first started using it. With cephfs, there is no fsck, so if you run into trouble, the procedure *should be*:
Alternately:
Or just pay somebody, such as 45drives, for a support contract. What we did was:
We wound up bringing in a second programmer to help me out with diagnosing how to recover from certain errors we encountered trying to reclaim lost inodes, making one-off patches to ceph daemons in order to log obscure details, copying files from a broken FS to a new non-broken one, and convincing a lot of staff that cephfs is forever as unreliable as some people ITT think btrfs is. We're now engaged in a years-long project to demonstrate that, no, actually, it's really nice, resilient, and a much better choice than our single-point-of-failure NFS on BTRFS server boxes. But it's an uphill climb. cruft fucked around with this message at 17:32 on Nov 1, 2023 |

I haven't lost any data in ceph yet, but I have lost weeks trying to figure out how to fix errors in the cluster, usually related to upgrades. It's absolutely not a plug and play product, you will end up in the weeds and learn more about ceph's internals than you ever wanted to. I still generally like it, it's a much more stable networked file system than anything else I've admined. I really like being able to do OS updates without users ever noticing. For local file systems I'm in love with zfs. Less of a learning curve (though you can make newbie mistakes that you'll regret later) and it "just works."

Is this what inetd is for? You certainly could, but if this is a computer with DIMM slots I'd encourage you to look at memory prices. I picked up 2x32GB in laptop SO-DIMMs last year for $120, and 64GB DDR4 desktop kits are under $100 now. New from retailers, I don't mean eBay hustling. Having 64 or 96GB of RAM is really nice and easy to do now. Not even expensive, like 1/3 the cost of any other component.

Other than the fact it appears that Wayland will eventually be the new standard, is there a compelling reason to switch to it in the meantime? I've been running KDE with the proprietary Nvidia drivers, and every time I tried to use Wayland in the past it rendered my system unusable - it simply couldn't reach the desktop. I haven't tried again in the last few years, partly because everything has been working fine under x11 and I like KDE and don't want to switch to another DE.

It's been "eventually" for the last 15 years, however in the last ~18 months it feels like it's suddenly hitting the point of critical mass and maturity that 'eventually' now actually feels like a actual point in time and not an abstract concept. Personally I mostly interact with my linux PC over xRDP and the lack of a good RDP solution for wayland is what has so far kept me on x11. However KDE are working on a rdp server so there's now an actual route to me making the switch.

It's pretty good and I feel like the performance under wayland seems better in general, plus if you're already using kde then you can keep using that with Wayland, so if you weren't using the proprietary Nvidia drivers I would say absolutely give it a try, but it's still buggy as gently caress with the proprietary Nvidia drivers I switched to Wayland + plasma because I got a 4k monitor and it's nice in general but I ended up having to get a new video card because I was also using the proprietary Nvidia drivers and it was too buggy (maybe it would have been better with a more recent Nvidia GPU? I don't know) mystes fucked around with this message at 00:42 on Nov 6, 2023 |

I have a 3080 on proprietary drivers and it’s pretty much been a nonstarter on Fedora with KDE. I need to read up on living with Wayland, though, just to see if I can’t tweak my way through poo poo to know what to expect ahead of time. That said I just learned Plasma has built-in tiling now, with a setup that knocks PopShell out of the water in my mouse-using-peasant opinion. So take all my statements with that grain of salt in mind. (In my defense I switched off Gnome like a month ago.) I also started using activities rather than just virtual desktops. Is there a way to set it so you have a different amount of virtual desktops per activity? For work I can make use of multiple virtual desktops but on the personal side two monitors more than addresses my needs.

CaptainSarcastic posted:Other than the fact it appears that Wayland will eventually be the new standard, is there a compelling reason to switch to it in the meantime? Yes, if you are at all sensitive to the mild jank that X has had forever. I was flipping back and forth when I switched to linux a year and a half ago, and at the time I encountered some pretty wild bugs using KDE-Wayland... But I eventually decided I would rather deal with wild bugs in exchange for how it felt better. X has always had a feel to me that is like a few grains of sand in a sandwich, extremely small but super annoying. Wayland felt just as good as Windows to me. (Better actually, once I got everything in KDE like effects & animation speeds just right.) OTOH I have an AMD GPU so haven't experienced the Nvidia problems. All the wild bugs I saw got fixed such that by a year ago it was pretty solid. And if you're 100% used to X so it doesn't feel at all deficient, none of that matters.

It might be better with an actual desktop environment with a compositor on x11, but before I switched to a 4k monitor I was using a 2k monitor and it was already barely usable with i3 on X11, because with a lot of stuff open it would get incredibly slow switching virtual desktops Wayland feels incredibly smooth and the fractional scaling works great in kde (basically I have it scaled so it normally looks similar to what it looked like when I was using a 2k monitor but it's sharper, and when I want to I can scale the font size down and still have it be legible), so even though I had to get a new video card I'm pretty happy with the result
