Manjaro is discontinuing 32-bit support and I'm annoy. >:U
* LagrangianRaptor
stares forlornly at urvogel.
<LagrangianRaptor>
… you use Manjaro on raspis, right?
<Ellied>
No, Manjaro had a raspi version for like a month before it got discontinued IIRC
<FluffyFoxeh>
probably because arch discontinued i686 and Manjaro is based on Arch
<Ellied>
they pulled that as an april fool's joke like a year ago so I wasn't sure
<Ellied>
figures
<FluffyFoxeh>
yeah ¯\_(ツ)_/¯
<Ellied>
I could wish that these distros would be a little less itchy to ditch 32-bit, seeing as one of the most common use cases for desktop linux is to revitalize old machines
<FluffyFoxeh>
yeah. I don't know what else is moving in that direction though
<FluffyFoxeh>
Arch, however, is probably not a good choice for old machines anyway due to its focus on the cutting edge
<Ellied>
There are a few news articles floating around that falsely claim that Debian is doing it, which is really just because the authors didn't actually read the announcement that says they are deprecating i386 in favor of *i686* which is still 32-bit
<FluffyFoxeh>
so they're likely to include all sorts of shit that won't work well on old hardware anyway
<FluffyFoxeh>
yeah I don't see Debian dropping 32-bit anytime soon
<Ellied>
I guess, except most applications tend to be hardware-agnostic aside from actual CPU instruction set
<Ellied>
Even the very latest linux applications don't tend to have *that* much bloat
<Ellied>
it's not like windows where trying to get the latest release to run on hardware from 10 years ago is like trying to get a toaster to run iOS
<FluffyFoxeh>
true
<FluffyFoxeh>
it'd mostly be the newer desktop environments that would be too heavy for resource constrained machines, but it's easy to find a reasonably well supported lightweight DE
<Ellied>
yup, xfce will run on a freaking potato
<Ellied>
and it's not about to go anywhere
<Ellied>
also, running Plasma with all the animations and effects disabled is working just fine on this old 1.66 GHz C2D with no graphics power to speak of
<FluffyFoxeh>
that is interesting to know
<Ellied>
I don't think it would have worked with Plasma 4. I think they actually made some effort to improve the viability of the desktop on older hardware in the new releases. I still hear a lot of people say that KDE is an overweight and resource-hogging desktop, but my experience tells me that those people haven't used it since 4.
<FluffyFoxeh>
it did seem that way on 4. I didn't mind because I have a relatively beefy desktop. Haven't tried 5 yet
<FluffyFoxeh>
I'm running MATE right nowe
<Ellied>
yeah 4 was really slow
<FluffyFoxeh>
-e
<Ellied>
I would have moved to xfce but KDE's really nifty taskbar widgets (especially for audio; I've yet to see a remotely comparable option for handling bluetooth audio streams in any other DE) and nice-looking theme options have kept me on it. Not that xfce doesn't have nice themes, but things tend to look more consistent in KDE as far as I've seen.
<Ellied>
if you can figure out how to get qt4/qt5/gtk2/gtk3 to look the same, but that's a battle anywhere you go :P
<FluffyFoxeh>
I have a pretty high tolerance for such things, I barely notice :p
<Ellied>
It's easy for me to suspend my fixation on theme consistency whenever I need to actually get anything done, but I enjoy fiddling with it in my spare time just to see what I can do
<Ellied>
most distros these days ship with a perfectly decent-looking desktop and set of application themes. It's just when you start wishing you could have the UI be light-text-on-dark that you go down a rabbit hole of nonsense.
<FluffyFoxeh>
hehe
<Ellied>
I intend to really double down on that if I ever get a laptop with an OLED display because it'll actually save power in addition to looking nice
<Ellied>
hopefully by the time those are common, some stuff will have been figured out to make that easier.
<FluffyFoxeh>
fwiw, for OLED I think it has to be fully black (i.e. #000000) for the pixels to turn off
<Ellied>
I would expect it to mostly use power proportional to total light intensity, no? but there are also plenty of themes that use fully black backgrounds
<FluffyFoxeh>
Perhaps. I'm not sure how the tech works
<FluffyFoxeh>
Just something I read
<Ellied>
I guess I don't know how OLEDs compare to regular ones in terms of efficiency and control circuitry. I'm assuming they're fairly linear in power draw to light output over the typical operating range, one way or another (presumably PWM dimming? idk)
<FluffyFoxeh>
another issue with dark themes is webpages. They're almost always bright backgrounds
<Ellied>
there are firefox extensions to try to fix that, but you can probably imagine how well those work.
awang has quit [Read error: Connection reset by peer]
<Ellied>
you can't just open the css and change all background-color: to #000 and all color: to #fff, you'd also need to find every image where someone's done black-on-white (or worse, -on-transparency) and value-invert them, and fix basically every other way of making graphics on the web in some way
<FluffyFoxeh>
might work okay with some decent heuristics for determining how to rejig the colour scheme
<FluffyFoxeh>
but yeah images will screw you up
<Ellied>
and there are lots of pictures and UI elements and things that simply won't work on a dark background the way they do on light
<Ellied>
I suppose it's possible that mass adoption of OLED might drive UI designers to switch to dark backgrounds
<FluffyFoxeh>
I'd be surprised
<Ellied>

my VPS has had 252000 failed SSH logins since September 1
<FluffyFoxeh>
238000 (94%) of them have been for the root user. It is not possible to remotely log in to the root account on my system. Good job bots :p
<FluffyFoxeh>
this is why I'm not concerned about allowing password logins. they don't get the username right 99% of the time (only 13 have been my username and some were probably me), let alone guessing the password

FluffyFoxeh: just switch ssh to some unused nonstandard port in the 10000s. I've done that for years now and they have never found it.
<FluffyFoxeh>
yeah, I could do that
<Ellied>
Those automated attacks are almost always just searching for default logins in my experience, probably hoping to find a garbage IoT device with a hardcoded login and add it to Mirai or something, but it could still probably save you a little bit of CPU to not have to constantly check and reject bad logins
<Ellied>
and it removes the possibility of one of them getting lucky
<FluffyFoxeh>
on the other hand, maybe it's better that they waste time on my server than something more vulnerable :p
APlayer has quit [Ping timeout: 383 seconds]
<Ellied>
Given that most devices being targeted are always-on, I doubt that will have any measureable effect :P
<FluffyFoxeh>
I wonder if this type of attack would be feasible if everyone used IPv6. it's not so easy to scan that address space
<Greys>
currently, but obfuscation is never a true defense
<Greys>
time and strategies will wittle down the target space
regex has joined #kspacademia
<Greys>
looooooks like, in the year 2002 asia occupied 32 million new IP addresses, compared to about 16 million between 1997 and 2000, so that's a pretty steep curve but this data is pretty small
<Greys>
if that were maintained, there would be in any given year about as many new devices as the previous three years, which is nuts
<Greys>
IPv6 is huge, but with that kind of acceleration it'll still get easy to find an occupied device quickly; especially given one of the intentions of IPv6 is the abandonment of NAT spaces, so every device on your network would have a public IP
<Ellied>
so basically the problem will expand to fill the new space without much trouble
<Greys>
yeeep
<Ellied>
I also didn't know that about abandoning NAT, that's interesting
<Greys>
and just like identity thieves don't target specific people, the bots and hackers don't care who they find
<Greys>
don't quote me on this but I also think IPv6 is supposed to get rid of port numbers also
<Ellied>
wait what
<Ellied>
how
<Ellied>
actually using SRV records?
<Greys>
the current usage of port numbers is basically used to route traffic through NAT gateways, and it's nearly entirely dynamic, so they don't represent anything of value, it's just a routing protocol now; so if you get rid of the NAT, you don't need them to get the message to the computer
<Greys>
in seeking greater opacity as to what any given encrypted connection is about, lots of protocols now don't use consistent port numbers on the client end, so that men in the middle such as comcast can't as easily make a guess at what a connection is and throttle certain kinds of traffic
<Greys>
UPnP port control on the router makes this rather trivial to automate
<Ellied>
waaaait a minute, I thought we still had net neutrality for the moment
<Greys>
my news sources keep getting distracted on that... I really don't know if we do
<Greys>
that said, comcast has been throttling and killing torrent connections for about 15 years; which is why a long time ago torrent clients started to have an option to randomly select a new set of ports every time they start
<Ellied>
have telecom companies ever been anything but slime
<Greys>
AoL started as a dialup game console cartridge system
<Greys>
you'd call in and read down games
<FluffyFoxeh>
port numbers aren't going anywhere. they are necessary to address applications running on a system
<soundnfury>
FluffyFoxeh: strictly speaking you _could_ have a separate virtual interface (and hence address) for each application
<soundnfury>
but that would be stupid
regex has quit [Remote host closed the connection]
<FluffyFoxeh>
quite
<FluffyFoxeh>
a port number basically is a local address
<FluffyFoxeh>
local to the given global IP
<FluffyFoxeh>
so you can extend one global address with a number of local ones
<FluffyFoxeh>
That's sort of a high level interpretation

Well, I can't really say much about it being well-accepted, but at least compared to the positions you see here definitely.

wow. it looks like hardly anyone on stackexchange/superuser actually knows two things about USB, but everyone and their dog is willing to weigh in with false information on threads about it. :V
<Ellied>
"Can I use USB 3.0 to connect two hosts on Linux? The spec explicitly defines this functionality." "No, USB is strictly host-to-device, not host-to-host; the master device has to drive the clock and the peripherals only respond when the master requests them"
<Ellied>
>usb
<Ellied>
>clock
<Ellied>
also the first part of that (strictly master-peripheral) was true of USB 2.0 and prior but is not true anymore of 3.0, AIUI, since now that the interface is full-duplex, crossover cables are possible
<Ellied>
and it is defined in the standard
<Ellied>
but yeah I'm not aware of any USB interfaces that have ever had clocks; they're all fully asynchronous to my knowledge
