really would love to not need xfce on my machine and log out/in whenever i want to play vr games :/
<ashkitten>
almost thinking of offering a bounty to anyone who can get steamvr working on sway on nixos
<ashkitten>
idk if anyone would be interested in working through that though
<ashkitten>
i've already patched wlroots and sway to support drm leasing, but for some reason even when i patch the xserver steamvr just creates a normal xwayland window that's not on the headset
<samueldr>
could it be related to the fhs env?
<samueldr>
I guess that would be one of the first thing you looked at though
<ashkitten>
dunno
<drakonis>
anyone wants to get together to play lancer rpg?

whenever i hear non-techy people talking about techy things and facepalm, i have to wonder if this is something that happens with every domain, that it's impossible to realise quite how dumb you're making yourself sound to people who actually know what they're talking about, without being one of those people

I am not sure being aware of the area's context is that reliable a protection, either. In general — yes, all areas have their options of rookie mistakes, but maybe different areas have different of risk of hitting them at the first step

Hm. German ~«Council of cities» seems to stress that public transport does not look to be a large infection risk and calls for people to use it more. Of course, a part of the reason it is easy to keep distance in public transport is that its use has declined quite a bit…

Could have just used my local nixpkgs, changed a thing and then ran a nix-shell against that. instead of rebuilding my OS against it
<elvishjerricco>
I don't understand homelabbers. I can't imagine how having like 6 different servers in your home is useful. One, I can understand, but the complicated stuff you see on /r/homelab seems 1000x overkill to me. All the things those servers are doing can probably be done on a single server if you build it right.
<__monty__>
Not really.
<__monty__>
You can't experiment with running a plethora of very heterogenous hardware on a single homogenous box : )
<eyJhb>
elvishjerricco: I understand it, because most is experimenting and the storage is so expensive! :p
<eyJhb>
And if you have a shitty connection, ohh...
<eyJhb>
But I have a little fetish for it as well...
<eyJhb>
I love it. But I guess you are meaning like full rack spaces?
<eyJhb>
Also, I am biased. I grew up with it
<elvishjerricco>
Yea there's people who buy whole servers for very specific tasks. Like, your esxi server can easily also be your plex server
<eyJhb>
BUT I NEED MORE GOD DAMN IT elvishjerricco !
<eyJhb>
:D
<elvishjerricco>
lol
<eyJhb>
But yes, have a VM server, create more from that
<samueldr>
or they know they'll break the esxi server often enought that kids/spouse/friends will be mad at the lack of plex
<elvishjerricco>
Your NAS can most likely be your esxi and plex server
<eyJhb>
I only have my two servers, and one of them is my router
<eyJhb>
It is waaay too OP
<elvishjerricco>
I guess if maximum uptime is your goal it makes some sense
<MichaelRaskin>
I am not sure if I have fallen out of context: you are explaining how to optimise a hobby by doing less of it, right?
<eyJhb>
For being a router.. And I only really use my server.. But I have my tiny VPS army as well. But a shitload of hardware. It is more fun having the basic hardware, to build test systems
<samueldr>
and there must be a part of exhibitionism in there
<elvishjerricco>
MichaelRaskin: Just lamenting that people on /r/homelab seem to overkill it like 90% of the time :P
<eyJhb>
But I guess MichaelRaskin is correct, it is a hobby
<eyJhb>
ANd therefore fun, and needs to be overkill
<elvishjerricco>
Fair enough
<eyJhb>
Also, sitenote, sitting with your laptop while recompiling hurts
<elvishjerricco>
I guess I can understand given the amount of money I've spent on Magic: The Gathering cards :P
<eyJhb>
But, I cet what you are saying elvishjerricco :p
<eyJhb>
haha, true
<samueldr>
also a fraction of them have insane stuff that is actually work stuff they use to work, so some of them cheat it's worklab@home
<MichaelRaskin>
It is also a good preparation to Cisco exams, I guess… it is rumored that a part of a grade is how many thousands of dollars in hardware orders you justify while designing a network
<eyJhb>
samueldr: or have bought it from old datacenters
<eyJhb>
THat is what my friends do
<samueldr>
oh, no, some are quite open about it being work stuff
<__monty__>
Thank you for the laughter elicited, MichaelRaskin.
<eyJhb>
But it sounds like a fucking jet taking off
<elvishjerricco>
I have three computers. One Threadripper desktop for compiling shit very quickly. One laptop to remote into that desktop. And one offsite backup server.
<__monty__>
Hmm, actually. Why do datacenters do AC to the box? We're talking fairly small distances no? Wouldn't centralizing the power conversion make sense?
<MichaelRaskin>
Erm, you do not want to run long low-voltage cables
<__monty__>
Is 12 too low?
<MichaelRaskin>
Thermal loss is I²R, so for a given cable with a given R, you want lower current. The server gets IU power, so you want higher voltage
<__monty__>
How about 200 and step down?
<MichaelRaskin>
Is stepping down DC more efficient that converting from AC??
<samueldr>
and it's not like it would use only one DC internally, it'd need a "power supply" type thing anyway
<__monty__>
Nah.
<__monty__>
What I'm imagining is having a big "power supply" at every rack that steps down to 12, 5, 3 whatever voltages you need.
<__monty__>
Wouldn't require ridiculous tiny fans and such.
<samueldr>
meanwhile having 120V A/C (or 2_0V/AC) input like the usual stuff makes it trivial to hook a server somewhere else than in a rack
<__monty__>
First thought was bring the PSU out of the 1U so it's not as restricted.
<MichaelRaskin>
You do not want that to run too far; both because of loss and because of EM shielding to maintain stability of voltage (for some consumers)
<samueldr>
I mean, it's not a bad idea, but I guess there is pragmatism in there that guides this
<samueldr>
the rack has no opinion on power
<__monty__>
Datacenters are big enough not to care about plugging servers in elsewhere though.
<samueldr>
so you can use any ol' rack
<MichaelRaskin>
I think specifically for 1U some people might do it
<__monty__>
Oh, right, UPS's need to do AC/DC -> DC/AC with AC powered servers. That must be an important factor and a large source of inefficiency?
<MichaelRaskin>
dunno about large; only a minority of power actually goes through the conversions in some designs
<__monty__>
What? How?
<__monty__>
When power cuts out you need to go from UPS DC -> AC.
<MichaelRaskin>
Yes, which is rare
<__monty__>
I guess.
<__monty__>
Though if you make the UPSes more efficient, they can be smaller, so you can have maybe an extra U or two per rack?
<__monty__>
Which makes for gains even if you never need to rely on the UPS.
<MichaelRaskin>
If you still need to adjust the voltage level, you are probably talking about low single-digit percentage points in savings.
<eyJhb>
MichaelRaskin: xpra does not seem to play well with some apps. Cannot see why... Anyone that has used xpra, heeelp
<MichaelRaskin>
Do these apps work with vncserver?
<__monty__>
MichaelRaskin: The article I linked claimed 8-10% efficiency improvement. That's fairly substantial afaict.
<MichaelRaskin>
Then you need to also have a single UPS per voltage?
<__monty__>
No.
<__monty__>
This is with DC stepping in the servers.
<__monty__>
Note that that efficiency figure is for the entire datacenter, it's not specific to a UPS.
<eyJhb>
MichaelRaskin: I would expect so, it is the keyboard input that is slow video playback is 100% working
<eyJhb>
Which is weird
<MichaelRaskin>
Maybe you should check. And possibly switch
<MichaelRaskin>
__monty__: I wonder if that includes switching form so-so AC↔DC converters to good steppers
<eyJhb>
MichaelRaskin: yeah, maybe
<eyJhb>
I will try to get all the errors away first
<__monty__>
MichaelRaskin: I have no idea. Wouldn't call those articles scientific. But I'm kinda convinced it could be a major thing.
<__monty__>
Cover the roof in PVs and you don't have to even have to DC/AC,AC/DC.
<__monty__>
Same with wind power.
<MichaelRaskin>
You need a _ton_ more UPS for that
<__monty__>
AC is easy to transform and transport and has some advantages for things like motors.
<__monty__>
But if DC is what you actually use *and* generate...
<MichaelRaskin>
Is the wind power no generating DC directly? For rotary AC is more natural
<ashkitten>
is there a way to override libraries in steam?
<__monty__>
MichaelRaskin: Apparently modern turbines often convert AC/DC then back to AC because it allows them to operate at varying windspeeds rather than just the net frequency.
<__monty__>
Also, "when turbines are sited offshore, the DC energy will be transmitted from the turbine to a central (onshore) inverter for connection to the grid." (wiki)
