hi
18:52
d2
I found a projets related to a REST interface, I sent an email to the team, now I see that there is a kind of project management system https://lab.apertus.org/T939
18:52
d2
can someone help me understanding this projets ?
19:02
RexOrCine
David?
19:03
RexOrCine
Ping d2
19:03
d2
yes
19:03
RexOrCine
Have you seen the thread in the Labs?
19:04
d2
this ? https://lab.apertus.org/T939
19:05
RexOrCine
Well that and: https://lab.apertus.org/search/query/eK9KKOsNKwPX/#R
19:05
RexOrCine
Note the higher the Task number the more recent.
19:05
RexOrCine
You'll likely want to speak with BAndiT1983 too.
19:05
d2
what is that https://github.com/apertus-open-source-cinema/axiom-beta-rest-interface/tree/develop ?
19:06
d2
something dead ?
19:07
RexOrCine
I'm not sure. 9 months old. Possibly. It's not really my area of research. If you stick around in the channel someone will go through the basics with you asap.
19:07
d2
ok
19:07
RexOrCine
Where are you based?
19:07
d2
italy
19:07
d2
but I'm french
19:08
RexOrCine
Ah. Good stuff.
19:08
d2
u ?
19:08
RexOrCine
I'm from Britain.
19:08
d2
an other continent xD
19:09
RexOrCine
Another world. Yeah, like I say, you wanna speak with Bandit or se6astian. I think there are a couple of students who are familiar with REST too and they're in here quite often atm.
19:10
d2
maybe you can answer some of the questions unrelated to the interface, what is running on the embed machine ?
19:11
RexOrCine
Again, not sure David. Sorry. I'm communications, networks and hardware assembly.
19:11
d2
ok so far from that
19:13
vup
d2: do you mean the linux distribution running on the camera? thats archlinuxarm
19:14
d2
yes, I saw this, but I mean what are the tasks performed by this small cpu
19:14
d2
is there any realtime requirements ?
19:15
RexOrCine
left the channel
19:15
d2
on the wiki, I see references to REST, to websockets to shell scripts, to cpp, to php ...
19:16
vup
as far as i know it only does basic controlling of the camera, all the processing is done in hardware, things like changing image settings should be fast, but I wouldn't say it qualifies as realtime
19:17
vup
currently most things are set with shell scripts, but they are going to be replaced by the control daemon mentioned it the webremote task
19:17
vup
*and python scripts
19:18
d2
if you run an unmodified archlinux you're not realtime anyway
19:19
Bertl_oO
no, no realtime .. all time critical stuff is done in the FPGA
19:19
vup
well we have a custom kernel anyway so adding realtime patches wouldn't be hard, but it probably won't be needed
19:20
Bertl_oO
the arm cores are basically used to configure, control and monitor stuff
19:20
d2
T939 @vup ?
19:20
Bertl_oO
(and to take a snapshot if you like)
19:20
vup
d2: yes
19:20
d2
ok, cool
19:20
d2
cool for both answers
19:21
d2
anything started ?
19:21
d2
someone wrote code already ?
19:21
vup
you can look at https://github.com/apertus-open-source-cinema/beta-software/tree/master/software that are the tools running on the arm cores
19:23
d2
so, the daemon is done, there is a way to communicate with it on a unix socket and the goal is only to specify and implement a rest interface ?
19:25
d2
doesn't look like that, there is pieces of unfinished stuff everywhere in this repos or I'm wrong ?
19:26
vup
you're quite right
19:26
vup
the daemon is not done yet
19:28
d2
and why is there a "daemon" ?
19:30
d2
because from what I got it's a pretty simple piece of software doing basic tasks, having a "daemon" and an interface over a unix socket looks like over engineering but probably I just didn't got it
19:32
d2
and rest ? you plan to pull ?
19:35
vup
a bit of reasoning is given in https://lab.apertus.org/T757
19:36
vup
but for more info on design choices you probably need to ask BAndiT1983 or se6astian
19:38
d2
yes, the problem is not to have a resident program that is necessary but to plug an external api over a socket
19:39
d2
more or less we want to replace all this https://github.com/apertus-open-source-cinema/beta-software/tree/master/software/scripts
19:39
d2
?
19:40
vup
yes
19:40
vup
and also https://github.com/apertus-open-source-cinema/beta-software/tree/master/software/cmv_tools
19:41
d2
and who is in charge of this ?
19:42
vup
BAndiT1983
19:43
vup
what whould you suggest instead of a socket?
19:44

I also found this xD https://lab.apertus.org/T931
19:48
d2
need to go
19:48
BAndiT1983
d2, we are targetting websockets now, so REST will be replaced
19:49
BAndiT1983
vup, daemon will be adjusted to new requirements, we have evaluated different approaches, so it's a bit of mess for now

20:18
d2
ok BAndiT1983
20:19
d2
and what vup said is right about what run on this machine ?
20:20
d2
there is nothing except this daemon that just run some scripts on demand and few hardware monitoring tasks ? BAndiT1983
20:21
BAndiT1983
this are planned features, currently daemon does just a basic stuff, as the hardware for testing is not always available
20:21
d2
because from what I read on the "lab" it look more like the performances are critical
20:22
BAndiT1983
zynq fpga is not that powerful, so it shouldn'T be overburdened
20:22
d2
what's the cpu again ?
20:23
Bertl_oO
dual core arm a9
20:25
slikdigit
left the channel
20:26
d2
it's not so far fro a A53 no ?
20:26
d2
it's 32 bits but the performances are not so different or they are ?
20:27
Bertl_oO
yeah, performance wise they are about the same
20:28
Bertl_oO
https://versus.com/en/arm-cortex-a53-vs-arm-cortex-a9
20:28
d2
so to do that there is a lot of ressources
20:30
d2
go and websockets then BAndiT1983 ?
20:31
BAndiT1983
go? nope, i'm c++ guy
20:31
BAndiT1983
go was used for last gsoc, had just to learn it to help the student
20:32
d2
so you develop that with c++ ?
20:32
BAndiT1983
yes
20:32
d2
ok, good luck ;-)
20:33
BAndiT1983
?
20:33
d2
nothing, just I won't follow :-)
20:33
BAndiT1983
still don't understand what you mean, but nevermind
20:35
d2
no I wanted to see if I could help but if it's done with c++ I'm not the best guy for that and not really interested but it's fine :-)
20:35
Bertl_oO
smells like a programming language war is coming up ...
20:35
d2
not at all
20:36
d2
that's the last stuff you need guys and I came to help :-)
20:36
BAndiT1983
so you are a guy who is focussing just on one language?
20:37
d2
no, I don't want to do c++ right now but it's fine there is no good or bad language there is only good or bad developpers and someone can be good on one language and bad on an other one
20:37
d2
so I don't want to be the bad c++ guy
20:37
d2
that's all
20:38
BAndiT1983
hm, software developer does not limit himself to just that
20:38
Bertl_oO
d2: how about 'whitespace'?
20:38
d2
?
20:38
BAndiT1983
d2, also a software developer remembers the technology, not the language related stuff
20:39
Bertl_oO
d2: the programming language 'whitespace'
20:39
BAndiT1983
you cannot suck at one language and be good at another, that's not what the professional companies expect
20:39
Bertl_oO
but some languages just suck, regardless how good you are :)
20:40
d2
you're ridiculous ++
20:41
BAndiT1983
some languages were created, because some people seemed to have too much spare time
20:41
BAndiT1983
whitespace is one of them, i suppose
20:42
d2
you know nothing about someone and you start insulting a person that came to help... who knows maybe next time it will be a person with 20 years of experience on managing successful project and you will loose this opportunity...
20:42
d2
left the channel
20:43
BAndiT1983
have i missed the insults?
20:45
BAndiT1983
seems like real software development is not for everyone, good luck with getting a job by such attitude
20:51
Bertl_oO
you are so brutal! ;-)
20:54
TofuLynx
Woah
20:54
TofuLynx
Surprised with this attitude... Didn't really see where it come from
20:55
Bertl_oO
yeah, BAndiT1983 is just a beast ... attacks out of the blue
20:57
BAndiT1983
the attitude comes from lacking of experience and thinking to be the master o f the universe
20:58
BAndiT1983
pity that he left so soon, otherwise i would show him a guy with over 25 years of experience and still attending the project ;)
20:59
BAndiT1983
TofuLynx, will look into the downscaler tomorrow, finally moved last stuff from old apartment
20:59
Bertl_oO
so you are now officially a hamburger?
21:00
TofuLynx
Great!
21:00
TofuLynx
Ahahahah a hamburger
21:00
BAndiT1983
no, frankfurter ;)
21:00
BAndiT1983
TofuLynx, there are frankfurter sausages
21:01
TofuLynx
I know these...
21:01
TofuLynx
They taste good
21:01
BAndiT1983

21:02

Btw, I will push the updated downscaler code
21:02
TofuLynx
on my github
21:02
TofuLynx
so you can check it
21:02
BAndiT1983
very good, cause i have lost a bit of track over the last weeks
21:03
TofuLynx
I will have to search on irc log your code as I had my PC formatted due to a bug with drivers and didnt upload your code
21:03
BAndiT1983
i can send it to you, should be on one of my VMs
21:04
TofuLynx
Can you send it today?
21:04
Bertl_oO
TofuLynx: you format your PC because of a driver bug?
21:04
TofuLynx
not that simple xD
21:05
BAndiT1983
have to prepare a dessert for fathers birthday tomorrow, if i get it done soon, then yes, otherwise sometimes tomorrow, at late afternoon i will be on train, then at latest
21:06
TofuLynx
I wanted to do a full clear of my computer (remove windows and make it linux only), and I messed with linux graphics drivers, so I simply formatted it for once and all. and it's working great :)
21:06
BAndiT1983
there is a new invention to prevent data loss, called backup
21:06
TofuLynx
yeah true
21:06
BAndiT1983
you have to say it like dr evil in austin powers ;) with finger signs
21:06
TofuLynx
I usually backup my things on the cloud
21:06
TofuLynx
wait
21:06
Bertl_oO
but to be fair, you only backup important stuff
21:07
TofuLynx
Ok It's not on my backup

21:07
BAndiT1983
and downscaler is not important??? ;)
21:07
Bertl_oO
do you have a mini-you?
21:07
TofuLynx
Ok I should of have been more cautious xD
21:08
BAndiT1983
sometimes i wish, especially in my job, so i can split all the work
21:09
TofuLynx
hmm
21:09
TofuLynx
do you have any idea when I first entered the irc chat?
21:09
TofuLynx
around the first week of february?
21:11
BAndiT1983
nope, second week is supragya there
21:11

just saw that
21:12

I wish I could be as active as I was in february...
21:12

21:13
TofuLynx
what is that xD
21:15
TofuLynx
btw andrej
21:15
TofuLynx
I wanted to ask you a thing
21:15
BAndiT1983
i'm just still laughing about good and bad language stuff, as you have to do the work even if you don't like a language
21:15
TofuLynx
Is the "k" in your name silent?
21:16
TofuLynx
j***
21:16
BAndiT1983
nope, it's fully spoken, but not in english way, it was adjusted for german, usually you would write it andrey
21:17
TofuLynx
it's that in portuguese we have a name "André"
21:17
BAndiT1983
french also, mine is the russian variation of it
21:17
TofuLynx
I see
21:17
TofuLynx
ok!
21:17
TofuLynx

21:17

BAndiT1983_
21:17
TofuLynx
most subscriptions in lab are for C++, to be honest, haven't expected that
21:18
BAndiT1983
?
21:18
TofuLynx
After the deadline, what do you think about the proposals?
21:18
TofuLynx
Surprised with anything related with it?
21:18
BAndiT1983
had just looked at some for now, still trying to think of a way to grade the challenge code and proposals
21:18
Bertl_oO
yeah, next year we will forbid C++ and use a proper programming language *G*
21:18
TofuLynx
ahahahahah
21:19
TofuLynx
what about making apertus language
21:19
BAndiT1983
Bertl_oO, we should not kick a person lying on the ground and not able to defend himself
21:19
BAndiT1983
the guy was possibly too young, the behaviour was similar
21:19
Bertl_oO
TofuLynx: https://xkcd.com/927/
21:20
BAndiT1983
there were nice series of articles about custom scripting lanugages back then, around 2001
21:20
BAndiT1983
Bertl_oO, i think that's your standard xkcd for most answers ;)
21:20
TofuLynx
aahahahah i loved that comic xD
21:21
TofuLynx
and do you think it will be harder or easier to grade the proposals, as they are in less quantity but in higher quality?
21:22
BAndiT1983
higher quality is our goal, e.g. challenge code, it's less about to get more and more features there, but to see structured code
21:26
TofuLynx
Ok :)
21:26
TofuLynx
btw I found the code
21:26
TofuLynx
so you dont need to check your VM
21:26
BAndiT1983
will still have to check the VM, to find the right one, should write a comment there, as i have 3 or 4 for different apertus areas
21:27
TofuLynx
wow xD
21:28
BAndiT1983
my tasks are not limited to OC or daemon, also website maintenance a bit etc.
21:29
TofuLynx
isnt website maintenance RexOr's?
