lanefu: it's deletes a post on linkedin every 30 minutes and posts it again, the same one
<stipa>
something like an advert
<stipa>
instead of me wasting time there trying to be at the top of the feed i did a python script to do it 48 times a day
<stipa>
i tried other stuff like with headless chromium but that didn't work since they somehow change the code of the linkedin or something so scrapers can't work anymore
<stipa>
but computer vision works ok
<stipa>
since it behaves like a human
<stipa>
very primitive AI
<stipa>
but, headless chrome and some other stuff would waste less resources and they could run from the CLI environemnt, but what can you do...
<stipa>
adapt or die
<stipa>
i had a problem with linkedin, script was clicking to fast
<stipa>
their system noticed and i was baned
<stipa>
they returned me account but i had to slow the vision a little bit
<stipa>
their system noticed that it doesn't behave like a human since it clicks and moves mouse like super fast machine
<stipa>
i guess
<stipa>
since i slowed it down they're not complaining
<stipa>
but they also don't know why i was banned since their systems are "Automated"
<stipa>
go figure
<stipa>
i was lucky

reclaiming workbench, only crying a little about throwing things away
<Tony_mac32>
don't even bother asking why there's a mason jat next to the oscilloscope
<Tony_mac32>
jar*
<stipa>
i don't like to throw things either, after some time i need to buy them...
<stipa>
like, i threw that 5 years ago, idiot
<stipa>
now i have to buy it
<stipa>
things are great for hasking stuff
<stipa>
hacking*
<stipa>
like, materials
<stipa>
that can't be made at home
<stipa>
like ,piece of flat piece of plastic from some packaging or something, but it costs money if you want to buy it and need it atm
<stipa>
even going to shop costs money...
<stipa>
but, then, there is limited amount of space...
<Tony_mac32>
haha
<stipa>

I think I've found a bug in armbian-resize-filesystem
<chrisd>
Wondering how to report it.
<IgorPec>
shoot
* [TheBug]
*BANG*
<IgorPec>
not you :)
<chrisd>
line 56 is supposed to align to 16MiB sizes
<chrisd>
but I think it's aligning to 16KiB sizes
<Xogium>
[TheBug]: damn it ! I told you just how many times to put a silencer on that damned thing ?
<Xogium>
;)
<[TheBug]>
:D
<chrisd>
The 32 should be 32768
<chrisd>
and later in the line the 3200 should be 376800

Hmm anyone have a guide on tuning nfs on armbian? Seeing some high load average with low CPU usage
<IgorPec>
armbian runs with lets say 20 different hw interfaces (kernels) on hundreds of different hw configurations.
<IgorPec>
on hw level we apply certain optimisations which should make some difference
macc24 has joined #armbian
<IgorPec>
while on the NFS protocol level, this is probably a question for NFS gurus
<Church->
Nod got it
<IgorPec>
on which hw do you do this?

IgorPec: Helios64
<Church->
So let me get the chip
<Church->
rockchip64/RK3399 hexa-core soc
<[TheBug]>
I mean, what are you seeing / expecting
<[TheBug]>
even if bound to one CPU, which it's not, you should be able to max gigabit network no issue?
<IgorPec>
which board specifically?
<[TheBug]>
I use NFS w/ mdadm raid5 on rk3399 (RockPi 4c) and not see any issue
<[TheBug]>
you are using ZFS if I recall
<[TheBug]>
so, maybe overhead from that is the issue
<Church->
Ah so I guess it's mostly precationary? Getting a 100% load average message from motd on ssh in. Load average is only 6.30~ from an upper bound. Haven't profiled what's out of turn for this box yet.
<Church->
Haven't noticed any degredations however
<[TheBug]>
thats wait
<[TheBug]>
check top when you see this
<[TheBug]>
look in the section for io wait
<[TheBug]>
this will probably be like 20-30%
<[TheBug]>
your system has high load because it is having IO wait some
<[TheBug]>
the load is artificial to actual CPU usage
<Church->
From iostat
<Church->
Yep it is
<Church->
I figured it was IO bound
<Church->
Given actual CPU usage was almost non-existent
<[TheBug]>
its supposed to give you an idea that things are being queued and that if you try now with a hard load, you may have wait .. so load is showing it believes current rate of work its backed-up a bit there, but if its still responsive/ doing what you expect, then this is expected
<Church->
Okay got it. Thanks!
<Church->
Just wasn't sure, first using a NAS and zfs that wasn't just a HDD attached to my htpc
<Church->
first time*
<[TheBug]>
hehe yeah.. also if you are newer to linux another fun gotcha is ram and how it is used can be confusing sometimes
<IgorPec>
yeah, ZFS can certainly add some troubles here
<IgorPec>
but am not paying much attention to zfs issues
<Church->
[TheBug]: Yeah my most recent manager gave me a great breakdown on RES/VIRT one day heh
<Church->
Yeah I assume most of the issue is the SMR drives. Will probably slowly replace them as they fail/get close to failing
<Church->
Although reads should be mostly fine there
<[TheBug]>
honestly the biggest issue in that case would be the drive not waking fast enough, you don't really have enough drives / probably not active enough to really cause issue from SMR specifically
<[TheBug]>
most people whom have that issue are in production where they are pushing the drives and the hardware arrays have a specific expectation of what the drive will do in a specific time, and if it doesn't results in errors
<[TheBug]>
I don't think you should really see that issue in a 5? drive array like you are trying
<Church->
Yeah it's just 5 drives in a raidz2, a single application (jellyfin) using it with almost no writes except in heavy bursts once every two weeks to add more media
<[TheBug]>
I have a setup where I have an 8 port raid card and then attached a drive via USB 3.0 to sata UAS and its a 9 drive raid.. and I can say the use of USB in that case can make a delay cause USB likes to power down the one drive -- I think that issue I have would more likely cause some issue / failure than you using SMR drives in array like you are.
<[TheBug]>
s/8 port raid/8 port sata
<ArmbianHelper>
[TheBug] meant to say: I have a setup where I have an 8 port sata card and then attached a drive via USB 3.0 to sata UAS and its a 9 drive raid.. and I can say the use of USB in that case can make a delay cause USB likes to power down the one drive -- I think that issue I have would more likely cause some issue / failure than you using SMR drives in array like you are.
<[TheBug]>
so far it's been okay, just some delay if requests haven't been made to it in a while
<Church->
Eesh yeah that delay could cause some fun issues
<[TheBug]>
but sometimes you will see usb reset in dmesg for example, which isn't good really in a raid.. its a testing setup to see what I could do...hehe
<[TheBug]>
bunch of old 2TB's
<Church->
Heheheh neat
