<nekomancer[m]>
yes, yes, it can be a problem source — kernel change 4.14 to 5.4.
<nekomancer[m]>
try to switch between this kernels both direction, keeping other system the same
<jl_67877>
I have not really played with kernels. Can I just swap to 4.14 and not rebuild the system?
<jl_67877>
I am not even sure where i get a usable copy of 4.14, I know dumb questions....
<nekomancer[m]>
try to do it with armbian-config utility
<archetech>
id go up a version
<archetech>
to like 5.6/7
<archetech>
what sbc is it
<jl_67877>
Okay, if I use armbian-config will it provide kernel options or do I need to download/install and possibly compile it?
<jl_67877>
The SBC is an oDroid HC2.
<jl_67877>
I have 5 of them as part of a MooseFS cluster.
<nekomancer[m]>
armbian-config will propose you some kernel versions, individual for every sbc model\
<jl_67877>
Cool. I need a uart serial before doing this to be safe.
<nekomancer[m]>
maybe dump of sdcard before you begin will be enough
<jl_67877>
Great point. I will do that too.
<jl_67877>
Gents, I have to run. Thank you for the advice!
<nekomancer[m]>
`clonezilla` good for disk image backupsand restores
<jl_67877>
I will check that out.

Should i be drinking matrix chat koolaid or is my weechat lifestyle okay
<lanefu>
Ive got the forwarder with the okay-ish android app
<c0rnelius>
i like the weechat app.
<c0rnelius>
could go full blown telegram. Isn't that what all the kiddies are using these days?
<nekomancer[m]>
some kiddies uses matrix
<c0rnelius>
yeah I saw that. smh and turned away.
<c0rnelius>
Whats happened to the good old days when they just integrated everything into one application? Like what Pidgin does or did... Is that even still around?

wasn't my doing, I promise. XD

I'm just going down the weecaht road, what's this noise?

<tonymac32>
lvrp16 5.5 days running at 2 GHz on the Renegade Elite (1.5 on the little cores)
<lvrp16>
tonymac32: passive cooling?
<tonymac32>
looks like 50% load due to memory limits with the rosetta@home packages
<tonymac32>
I have a small fan pointed at it (and a tinker board and an XU4)
<tonymac32>
so passively active cooling
<tonymac32>
:D
<lvrp16>
haha
<lvrp16>
just waving your hand is enough to cool it lol
<tonymac32>
The case does good work, it just needs a tiny bit of air movement
<tonymac32>
it's at 55C
<lvrp16>
no case can defy physics, too bad
<tonymac32>
A pity
<lvrp16>
I could build a weird shape that is 2x as effective at passive cooling but 2 x 0.01 is still 0.02
<tonymac32>
It does increase the surface area a lot, so that's always helpful
<tonymac32>
hahaha
<tonymac32>
For any use other than what I'm doing it is more than enough
<lvrp16>
I just bought a 13 inch PD Type C display off Amazon to play with Renegade Elite next week
<lvrp16>
$270 not bad
<tonymac32>
nice
<lvrp16>
for $100 worth of hardware
<tonymac32>
2x BOM + Amazon
<lvrp16>
probably only profitable display on Amazon lol
<tonymac32>
;)
<tonymac32>
yeah
<lvrp16>
55 inch, also $250
<lvrp16>
XD
<lvrp16>
with free shipping
<lvrp16>
vs 13 inch
<tonymac32>
my 28" 4K was $250 or so, with a sale
<lvrp16>
BOE is driving everyone out of business
<tonymac32>
it fits the trend
<lvrp16>
winner takes all, gotta do what you gotta do
<tonymac32>
My only position on international trade is reciprocity. Other than that, have at it
<tonymac32>
I think China would be able to adapt to that. The EU, on the other hand...
<tonymac32>
(VAT is one of the biggest BS things I've ever heard of)
<lvrp16>
I blame all of the english and business diplomas that were printed for $200K that aren't worth more than the paper it was printed on
<tonymac32>
I agree
<tonymac32>
I'm absolutely OK with people studying whatever they want, but
<tonymac32>
There is a cost to this, which is going to be spread to society at large
<tonymac32>
(My engineering degree was not $200k and I am still not certain it was worth the cost in retrospect)
<lvrp16>
thank god for factory automation and diligent capitalists in China, otherwise America would be pretty poor right now.
<lvrp16>
that display I bought would not exist for any price.
<tonymac32>
Hehehe you are trying to get some insane cognitive dissonance going for people unfamiliar with modern China
<tonymac32>
There could be long and drawn out discussions about currency values and such, but yes, while the US could/would continue to push technology without China, it would not be as fast.
<lvrp16>
yeah, left and right both insane right now. the truth is in the middle.
<tonymac32>
It almost always is
<tonymac32>
Someone may have been eavesdropping on me, or they had exactly the same idea I had at the same time, so my Atmega32U4 with ESP32 port design is being shelved, thankfully I had only put time into it, not money yet
<tonymac32>
not ESP32, too fast typing, the ESP8266 small module
<tonymac32>
I mentioned the wireless bits in a chat somewhere, need to double check histories
<tonymac32>
cut throat bunch these makers. XD
<lvrp16>
tonymac32: you start with your gd risc v stuff?
<tonymac32>
shhhhhh
<tonymac32>
:D
<lvrp16>
XD
<tonymac32>
It only took 3 months to get the IC's rofl. I don't think that's really going to work out, but yes I am finishing up the design
<tonymac32>
in 3-4 years no one showed any interest in microcontrollers on Pi 0 form factor, and now I have a competitor it seems. ;)
<lvrp16>
tonymac32: they'll copy anything no matter how ridiculous
<lvrp16>
tonymac32: insane herd mentality, very little independent thought
<tonymac32>
Who are you calling ridiculous? XD
<lvrp16>
:P
<tonymac32>
I saw an adapter from Pio to Adafruit feather
<tonymac32>
so OK, cool
MrFixIt has quit [Remote host closed the connection]
<tonymac32>
it is getting a lot of attention and congratulations
<lvrp16>
but it's like...how many people buy that stuff?
<tonymac32>
yeah, I don't really see why you'd adapt that
<tonymac32>
Pi is the bigger ecosystem
<tonymac32>
I doubt there's anything significant for a feather that isn't already a hat on aliexpress
<tonymac32>
XD
<lvrp16>
Yeah, I kind of want to stomp on anyone that asks me where config.txt is.
<lvrp16>
But then I realized that they are right.
<tonymac32>
If you want DIP package the feather makes sense, but the small number of IO makes it really a bottleneck for bigger processors
<tonymac32>
config.txt. sigh
<tonymac32>
Arturo put an i.MX on a feather. THat's cool, but you have a 600 MHz 12 IO chip, or something like that
<lvrp16>
LOL
<lvrp16>
I'm going to build an RK3399 board with 1 GPIO output
<tonymac32>
If I was going to do a chip with that kind of capability, I would have to pick a bigger form factor, like Arduino or RPI A
<lvrp16>
It'll be the bestest GPIO output ever
MrFixIt has joined #armbian
<tonymac32>
and then it would have IDC connectors or something
<tonymac32>
and lol
<tonymac32>
That feather is without a doubt the fastest micropython machine in existence (Or CircuitPython, since apparently there was a falling out I don't know all the details of)
<lvrp16>
I should learn python one of these days. The identation threw me off from the language.
<tonymac32>
yeah, that's the only weird thing, indentation is the entire structure
<tonymac32>
otherwise it's like you took C and BASIC and... mixed them
<lvrp16>
I remember back in college we had one course on Python and when tabs and spaces were different, my interest died right there.
<tonymac32>
but still no GOTO's
<tonymac32>
you have to get out the final, bedrock reality of Assembly to get those back
<lvrp16>
that and the python 2 vs python 3 debacle
<tonymac32>
MicroPython is Python3
<tonymac32>
since 2 is not supposedly done
<tonymac32>
I'm still a newbie to Python, so the history is not known to me
<lvrp16>
I've only ever designed distributed web apps and PHP+redis is just lightyears ahead in performance department from Python.
<tonymac32>
haha. I use python for manipulating huge datasets where I know what I want out of them
<lvrp16>
yeah but for web back in the day it was all django, which did like 100 requests a second when I needed 100K/s
<tonymac32>
and I'm talking about DAQ input over a series of days type of big data
<tonymac32>
oof
<lvrp16>
for offline processing via library calls python would make sense
<lvrp16>
but numerical crunching is so damn slow too
<tonymac32>
Yeah, chugging through CSV's looking for peaks is a perfect task
<lvrp16>
for csv's python is slow too...
<lvrp16>
numerical processing is just too slow on python unless you offload to an optimized library
* tonymac32
can't remember the library he was using
<lvrp16>
processing in general
<lvrp16>
hell, even php has a proper iterator and JIT these days that rapes python on speed
<tonymac32>
I won't disagree, but for one-off datasets I can get the filtering done in minutes and let the computer chew on it while I eat lunch
<tonymac32>
which is really why I use it
<tonymac32>
For anything else I'd look to a compiled option TBH
<tonymac32>
Java is dead to me
<tonymac32>
XD
* tonymac32
remembers Lotus Notes
<tonymac32>
yeah, and the SAP interface
<lvrp16>
blessed is progress
<tonymac32>
I think we're going backward in some things. Some of these framworks for app building are bigger than a properly constructed operating system
<tonymac32>
when "Hello World" is 50 MB, well
<archetech>
like Qt
<tonymac32>
ugh
<archetech>
puts out a decent result though
<tonymac32>
There are clear cases where the size of the program is not critical
<tonymac32>
but in typical human fashion, people go nuts
<archetech>
using on automotive arm based dash screens so the executables arent very big

Good morning. IgorPec lanefu spreadshirt has more stuff that can be printed, that is correct. I decided to not simply include everything available because most of the shirt variants almost look the same and some stuff is useless. And no, they do not have any underwear at all :P

This morning, I tried to test some Radeon tools for GPU debugging. The bin release was bound to an old version of tinfo.so.5
lauri has joined #armbian
<Miouyouyou>
I had to hexedit the bin file to change it to tinfo.so.6
<Miouyouyou>
But that shows the issue with dynlibs and bin releases. You generally have to either provide all the libs, compile in static or thinly setup your ELF deps so they don't refer to specific versions
<lanefu>
i've heard good things about electron and etcher
<Miouyouyou>
Yeah, it's very light

i use etcher on my mac, and `dd` on my linux
