@djsmiley2k That's why you click custom server.
The only difference between my Riot and the public one is I changed the default matrix server it points to.
 
12:34 AM
@barlop You connect to the printer, then set it up to connect to the network,
 
12:56 AM
Riot is back.
 
1:33 AM
@rahuldottech YOU ARE DEAD TO HIM!

@JourneymanGeek AND HE IS DEAD TO ME
 
2:53 AM
@JourneymanGeek thanks, yeah I notice now I nistalled the driver I click file..print and it sees the printer, i'll do that for any computers I add to the network. I guess maybe the driver uses that printer WiFi/wireless access point of sorts. I don't think it should really show up as a network for my computer to connect to though! The only wireless networks I would want to connect to from that taskbar icon are for the internet!
 
3:33 AM
Having multiple versions of python installed is confusing...
 
4:00 AM
@MichaelFrank why do you have multiple versions?
MacOS?
 
Ubuntu, but I don't know why I have multiple versions.
 
Guys!
I got into college :)

@rahuldottech Congrats!
 
It's sorta expensive and not very prestigious and not my primary choice, but it's nice to know that I have this to fall back upon if nothing else works out
@MichaelFrank thanks!

@studiohack... did I see you come up on the users list?

7:07 AM
 
@Ave It's been fixed now
But yeah, that was super weird
(you're talking about the wall of text consisting of linux commands and outputs, right?)
 
Ave
7:29 AM
@rahuldottech yes
 
Ave
7:43 AM
@rahuldottech congrats, btw
 
@Ave Thanks!
 
7:55 AM
@rahuldottech Looks like someone had the idea to archive it on the Wayback Machine: web.archive.org/web/20190412072115/http://matrix.org
 
Ave
8:11 AM
wow
 
looks like someone took 'em to the cleaners, huh?

10:14 AM
@Ave Matrix locked all those down
 
monitor log files to stop relying on external sites?
what does that ev en mean?>
 
Ave
10:27 AM
@MichaelFrank I'm aware
@djsmiley2k external whitehats, not external sites
they're calling themselves a whitehat
 
Yikes
Seems pretty grey on the hat spectrum to me
Jings
those issues

Makes me think that Matrix was built by a ubuntu user.
 
Don't let quix hear you talk like that ;-P
 
12:30 PM
@tereško best queue, but bit unsavoury, maybe
@Ave k yeah I'm blind, but... monitor for what?
build logs? server logs?
sure, you can do clever things by monitoring log files, but it doesn't replace having a good whitehat looking at things.
 
1:41 PM
holy crap; SSD prices have taken a nosedive... in June 2018 I spent $1698 per drive for 2 x Samsung 860 Pro 4 TB, which now cost $920; the 860 Evo 4 TB, which just won't last quite as long, is only $661!
this is great... who's pushing prices down like this???? and this is retail from amazon.com!
 
Bob
@allquixotic I just bought a 1 TB 860 EVO for $180
Which lead to this:

Q: PCIe v3.0 SATA-III controller

BobI'm looking for a PCIe-based SATA card, to add more internal SATA-III ports. While a great many of them exist, most are based on an old Marvell series of controllers or the equivalent ASMedia (ASM1061?) controller, which only support PCIe 2.0. Due to a lack of motherboard PCIe slots, and a desire...

(answers appreciated :D)

Intel processor shortage ripple effect.
On Matrix, I posted this a while back:
> Intel's processor shortage is affecting so much of the PC component market. I'm actually a bit worried that this indicates that Intel, as a company, has gotten so large that it is "too big to fail", a single point of failure for the whole PC industry.
 
 
It's very worrying because the whole industry is utterly reliant on Intel as a supplier of processors for the PC market.
Too big to fail.

nah
arm would rise up

Q: Slow Transfer Speeds When Multiple Raspberry Pi Zero Ws Connected Over WiFi

PiManI'm working on a project that uses the pi camera module and 35 or more Raspberry Pi Zero Ws to take pictures and send them back to a central computer. Everything works fine with just 1 Pi connected, I get a transfer speed of ~2MB/s over wifi and it only takes about 10 seconds to transfer the pict...

get better wifi

Q: Cisco 5915 router message traffic

OldGuyNewTricksI am just learning so please forgive the simple nature of my question. I understand that routers have four (4) types of memory: ROM Contains the power-on self test and the bootstrap program for the router. The ROM chips also contain either a subset or the complete router IOS NVRAM Stores the ...

Sigh

Huh?
 
hmm?
 
Two mounting points for the same device?
 
that's.... clever?
it's possible
 
> mount | grep sda2
/dev/sda2 on /var type ext4 (rw,relatime,data=ordered)
/dev/sda2 on /var/lib/docker type ext4 (rw,relatime,data=ordered)
 
rmount or something fun
 
7:59 PM
Thing is... I have no idea how I managed to do that
I installed alpine linux on this server I just rented
And then ran this and then ran that and pasted this and pasted that and...
 
mound /dev/sda2 --bind /var/lib/docker
 
Wouldn't it show as "bind" or something?
Because... The content is different on both mounting points
If it was a bind mount, wouldn't it mean the content is the same?
And if it's /var and /var/lib/docker, wouldn't it be an infinite loop?

Bob
welcome to cgroups, probably
 
@ThatBrazilianGuy No reason why not
 
Oh god I just realized I know nothing about mounting
Life is a series of realizations of how little you know. .___.
 
8:11 PM
Ah, TIL
 
what u doine
 
cgroups are used by both Docker and LXC (and others)
 
pretty sure brazilians know stuff about mounting :D
 
@djsmiley2k (ಠ_ಠ)
 
beat me to it :P
 
8:12 PM
:D
made me actually lol there @bertieb
 
:P
 
sigh
no game keeps my attention anymore
i need to code more, or something
anyway, wut you learnin? cgroups?
 
@bertieb
but you too
 
I have no idea what I'm learning. For work it's most of random assorted bits of knowledge. Lately a bit of docker stuff, it's been a few weeks or maybe a couple months I haven't coded anything properly and I feel in a sort of limbo where I'm not exactly a dev and not exactly devops / sysadmin.
And I want to learn cool stuff in this area but there's no decent infrastructure. All our team has is a shitty server with 4 cores and 8GB RAM to run a dozen services =/
 
8:16 PM
Apparently DevOps are were the big reais are
 
So there's no load balancing, orchestration, kubernetes, rancher, or any cool stuff
 
Accroding to the StackOverflow Developer Survey⅒
oh ⅒, you're not ™
2
 
IMHO, "full stack" means "you're doing the work of three and getting paid as one", and "devops" mean "we now fired our sysadmins, their tasks are now yours"
 
and "sysadmin" means "I wrote a bunch of scripts to do my job for me" ?
 
yes.
I'm a networks guy
 
8:23 PM
Which means you manually add entries on the DNS zone and keep a list of subnets on an excel file?
(...I might or mightn't have seen both, ahem, somewhere)
"Hey I'm running command `abc` to try to do `x`, it doesn't work, any suggestions?"
"To do `x` you must run command `abc`"
 
@ThatBrazilianGuy we have a list of our subnets, in excel files
including every single assigned IP
we're talking about 100 tabs here
errr, sheets.
 
8:42 PM
@djsmiley2k Oh and I'm also on the first steps to running my own mail forwarder on a server, so I can get mail sent to my own domain and routed to my gmail account
Oh and I finally bought a domain for that.
Did you hear that, @rahuldottech? You're not the only one with vanity domains here anymore!
Only thing kid's got more than domains is girlfriends :P
 
rofl
 
9:08 PM
@ThatBrazilianGuy I was looking into setting up throwaway webdev environments on Docker so I can easily spin up projects while learning.
 
Yeah, it saves a lot of time and at first seems amazing and you fall in love. Then there are the gotchas and you spend a lot of time in order to save a lot of time...
 
I still don't know how to debug python properly
 
9:28 PM
Yay, I can do (basic) DNS! \o/
Got the A, CNAME and MX records working!
(no mail server yet just the DNS entry so any messages are happily going to /dev/null)
 
@djsmiley2k Find the bug, fix it!
 
...but who'd be sending email to a domain that's not listed anywhere?
 
China probably.
Or Nigeria.
 
@MichaelFrank well I found it
it's reading /sys/class/hwmon/hwmon1/device/temp1_input
but getting nothing as a value
cpu = open('/sys/class/hwmon/hwmon1/device/temp1_input','r')
for line in cpu.readline():
cpu_temp = (float(line) / 1000)
print ("cpu_temp is %s" % cpu_temp)
cpu.close()
it 'almost' works
 
11:19 PM
eww Python :P
 
!!s/eww/yum/
 
@bertieb yum Python :P (source)
