ItsMeLenny I was under the impression that if you were to click on that link you'd be able to browse chat history... on mobile at least.
04:02
ItsMeLenny
RexOrMatrix[m], i dont have it on movbbile, when i click it it takes me to a page witha button that says view in telegram, and a way to try it now which makes me want to try an account
04:02
ItsMeLenny
its a pretty sketchy program imo, compared to most
04:05
RexOrMatrix[m]
Yeah that sounds like what it does on Desktop. Not sure why you think it's sketchy. Compared with the most common ones e.g. Whatsapp it's top drawer. It's partial open source, servers are closed.
04:06
RexOrMatrix[m]
If there's something better with similar features I'm unaware of it.
04:07
ItsMeLenny
discord? not that ima fan of it but compared to the sketchyness behind telegram
04:07
ItsMeLenny
even this "Cryptography experts have furthermore criticized Telegram's use of a custom-designed encryption protocol that has not been proven reliable and secure."
04:07
RexOrMatrix[m]
Well that sounds like an article that did the rounds about five years ago.
04:08
RexOrMatrix[m]
Discord I've yet to be convinced about. But I did try it.
04:18
RexOrMatrix[m]
Yeah, still don't see any significant improvements since it was trialed.
05:39
ItsMeLenny
havent seen any in irc either
05:42
ItsMeLenny
but anyway, i cant access telegram, has anyone logged the chat online about it
05:42
ItsMeLenny
even uses the same sensor doesnt it
05:44
RexOrMatrix[m]
The Octopus? It's a closed source, proprietary camera inside a second enclosure. Not sure what the camera manufacturer uses but they aren't about to open up their camera to the whole world.
05:46
ItsMeLenny
it says its "powered by linux", uses an intel nux7i8dnbe processing board, with an i7 8650um , and either a CMV20000 or Sony IMX253 sensor
05:47
RexOrMatrix[m]
The Octopus is basically an enclosure, that's all, with third party devices inside it. It's not open source. Looks like someone has seen the planned arrangements for AXIOM Recorder and got inspired.
05:48
RexOrMatrix[m]
Not sure what sensors the camera manufacturer uses. They make industrial cameras. Many variaties in all shapes and sizes.
05:48
RexOrMatrix[m]
And with all sorts of sensors no doubt.
05:48
ItsMeLenny
i just said the 2 sensors it uses
05:49
RexOrMatrix[m]
I don't know which camera specifically it is.
05:49
ItsMeLenny
pardon?
05:49
RexOrMatrix[m]
The camera manufacturer isn't the people behind Octopus.
05:50
ItsMeLenny
the camera manufacturer isnt the people behind the camera?
05:52
RexOrMatrix[m]
It's a closed source, proprietary, industrial camera wedged into a second enclosure. Octopus are the people who want to sell someone else's camera in a second enclosure. Therefore if you have any problems they'd swiftly direct you to the actual manufacturer... Who'd charge you for replacement or repair no doubt.
05:53
ItsMeLenny
whats the original camera called
05:53
RexOrMatrix[m]
Phwar. Can't remember. It's an industrial cam outfit.
05:54
RexOrMatrix[m]
Ximea.
05:54
ItsMeLenny
the octopus lists all the parts it uses, which i just listed half of them
05:54
ItsMeLenny
ximea is the sensor
05:54
ItsMeLenny
i see what you're saying now
05:55
RexOrMatrix[m]
No. Ximea is the camera manufacturer.
05:55
ItsMeLenny
ximea has come up here a long time ago cos they use the same sensors as axiom
05:55
ItsMeLenny
ximea are like usb3 cameras and stuff ye
05:56
ItsMeLenny
forgot ahbout them
05:57
RexOrMatrix[m]
Anyways, despite what everyone is saying, it's not open source by any means. Not open hardware either.
05:59
ItsMeLenny
i think its open source in the sense that you can buy all the pieces and run the same OS, as its basically a computer with a usb webcam attatched
05:59
Y_G

06:02
ItsMeLenny
on a side note i didnt realise davinci resolve finally had a free linux version
06:04
RexOrMatrix[m]
If it was open source they'd say it was open source. They call it an 'open platform' instead. The cinegear news website call it 'open source', probably because they don't know the difference and the word 'open' was used in its marketing materials.
06:06
RexOrMatrix[m]
I'm not sure what you can and can't do with it in fairness. It's not really all that interesting when compared with what the project is about.
06:12
RexOrMatrix[m]
Hope I didn't sound snobbish there. What I mean is, we're a community that's building a camera from the ground up, those guys are building an enclosure of some sort.
06:14
Spirit532
I believe the Octopus is just an Intel NUC with a Ximea ribbon cable head
06:14
Spirit532
I have a MQ022CG-CM from them - the camera is wonderful, built like a tank, tiny, and the API is also super easy to use
06:14
Spirit532
But the price comes with it
06:15
Spirit532
The sensors they're using are definitely of the machine vision kind, with only a few baaaaaaaarely scraping the cinema world. The dynamic range is lower than the already low DR of the CMV12000 on most of them
06:16
Spirit532
There is no point in buying the Octopus at whatever insane markup they decide to put on it, as you can buy all the same parts in retail(or close to retail, Ximea only does proforma and b2b), stick them in a fancy box, and write your own CDNG writing software
06:17
Spirit532
Because the nuc won't be powerful enough to do anything besides dumping CDNG onto the SSD or doing ugly low-bitrate compression(OBS or something)
06:18
Spirit532
I built a "cinema camera" out of my CMV2000 head, and it performs just about as well as you'd expect. Meh dynamic range, but clean global shutter image when well lit. Useful? For sticking into tiny places, maybe, which the Octopus can't do.
06:18
Spirit532
But I believe even the cheapest Ximea cameras are over $500
06:22
RexOrMatrix[m]
I have to keep wondering if it's the Craft guys... Who borrowed heavily from AXIOM on the first planned venture.

Meeting time?
17:14
Fares
se6ast1an mentioned last week they might not be able to attend because of the maker faire
17:15
se6ast1an
yes I am here but internet on train is unreliable so rex offered to lead todays meeting instead
17:15
se6ast1an
RexOrMatrix[m]: ?
17:16
apurvanandan[m]
So should we postpone the meeting probably?
17:22
se6ast1an
I guess that would be best, Bertl_zZ is also still on the road, as is BAndiT1983|away
17:23
se6ast1an
We can try to do it tomorrow
17:23
apurvanandan[m]
Great, no problem!
17:24
se6ast1an
skipping it entirely until next week would probably not be good right now as the final gsoc week has now started
17:24
Fares
at the same time?
17:24
se6ast1an
yes, same time as always but tuesday
17:24
se6ast1an
in 23.5h basically :)
17:24
Fares
Great!
17:24
se6ast1an
I will also write an email when I get back
17:24
RexOrMatrix[m]
Ah, of course. The time difference.
17:25
RexOrMatrix[m]
Meeting in half an hour.
17:26

(GMT is an hour behind Vienna time. Slipped my mind)
17:31
RexOrCine
Is everyone present for the meeting at this point?
17:32
RexOrCine
Please message me if you'd like to speak and we'll do it in that order.
17:33
Fares
I'm present, but will it start now or in 30 minutes?
17:41
RexOrCine
Depends if people are here or not.
17:42
Nira
I'm also here, no problem for me
17:45
se6ast1an
sounds like it can be done today, great
17:48
RexOrCine
OK Fares do you want to go first... For the reader - Fares is working on JPEG Lossless Encoder Core. His tidy work can be found here - https://wiki.apertus.org/index.php/JPEG_1992_lossless_encoder_core
17:50
Fares
yes great!
17:50
Fares
hi everyone
17:50
Fares
last week I continue working on things related to integrating the core with the rest of the SoC
17:51
Fares
I implemented a partial reset for the core that will happen after every frame, so it now can handle stream of frames
17:51
Fares
and I also implemented a module to convert 16bits output to 40bits, which is needed for the LVDS
17:52
Fares
I also continue working on the report adding two sections, performance analysis and explaining the core configurability
17:52
Fares
that would be all, thank you
17:57

OK Nira, please go ahead... For the reader - Nira is working on AXIOM Remote software. I don't have a link to her Wiki page yet.
18:04
Nira
thank you and hello everyone
18:04
Nira
this week I first ended the script to test the code
18:04
Nira
I have continued with the debouncing code, so I have added some cases I hadn't considered before
18:04
BAndiT1983
changed nick to: BAndiT1983|away
18:04
Nira
and I have been sorting what I want to have on the documentation, and been writing about it
18:09
RexOrCine
Anyhting else?
18:09
Nira
that's it from me, thank you
18:10
RexOrCine
Can you tell su what debouncing code is?
18:10
RexOrCine
tell us*
18:12
Nira
when pressing a button there can be some bounces (fake pulses), so my code would avoid that and report only a press when it is 'real'
18:13
RexOrCine
That's excellent thank you.
18:15
RexOrCine
OK apurvandan, please go ahead. For the reader - Apurva is working on implementing gearwork and communication interface for the USB 3.0 plugin module. A Wiki page for his work is here - https://wiki.apertus.org/index.php/Gearwork_for_USB_3.0_Plugin_Module
18:16
apurvanandan[m]
Hi everybody
18:16
apurvanandan[m]
This week, I completed the channel bonding of the five LVDS lanes in the plugin module
18:17
apurvanandan[m]
Now I have perfectly working 40 bits gearwork work from the Virtex to Plugin. I tested the BER of all five connections together and it is lower thatn 10^-12
18:18
apurvanandan[m]
Almost all gearwork is complete now
18:21
apurvanandan[m]
Things which are left to do are: 1) Increase the Bandwidth from 2.4 Gbps to 3.0 Gbps, 2) Write the code that sends the data from AXI FIFOs to the encoder instance on Zynq, 3) Debug the issue in data transfer due to high CPU usage. Currently I am debugging the code on Remote Beta alongwith creating documentation and report.
18:22
apurvanandan[m]
Also some sort of gearing in the software level on the PC for recreating the frames
18:22
apurvanandan[m]
Thats all I wanted to say, thanks to all
18:23
Fares
apurvanadan[m]: about BER, is there a way to detect and fix the errors, that may be implemented in the future?
18:24
apurvanandan[m]
Apparently, I wasn't able to detect any error till now ( I tested till 10^12 bits), but yes ECC and CRC will be good to implement
18:25
apurvanandan[m]
Main issue at this time is the FT601 chip, it stops to receive data when the CPU usage gets high and my FIFOs get full hence a overflow
18:26
apurvanandan[m]
I have done completely unidirectional data flow without any feedback signals to the Zynq board
18:26
apurvanandan[m]
So I am not able to prevent FIFO getting full
18:27
apurvanandan[m]
So the FT601 interface needs to be worked on more, but the 6 LVDS lanes are tested and performing well enough.
18:29
Fares
mmm ok I don't get everything but good luck :) I hope you fix it soon, I was worried about BER since a single bit error in an LJ92 frame will corrupt the rest of the frame not only the pixel, but we can test it later when implemented.
18:29
Fares
sorry for interrupting the meeting.
18:30
apurvanandan[m]
Ok It will be great working on your code :)
18:30
apurvanandan[m]
Thanks
18:30
RexOrCine
Not at all, it's really good to see collaboration.
18:31
RexOrCine
Anything else you wanna mention Apurva?
18:31
apurvanandan[m]
No, I am done
18:31
apurvanandan[m]
Thanks for your time :)
18:32
RexOrCine
OK Y_G please go ahead... For the reader - Yash is working on the communication between the graphical controller between the Web Server and the Control Daemon on the camera's firmware. A wiki page for the task is here - https://wiki.apertus.org/index.php/Extend_Camera_Control_Daemon
18:32
Y_G
Hi All,
18:33
Y_G
This week worked on going through /testing all the work done,to see if everything was in place .
18:33
Y_G
Made changes to the CLI .Added functions to help segregate different types of request as the number of parameters were different for each type of request. Yet to test it in Beta as it is not available currently.
18:34
Y_G
Worked on completing the documentation for the work done till now .
18:34
Y_G
This week will mostly focus on completing the Unit Testing part .
18:34
Y_G
That would be it from my side.
18:35

Y_G what is CLI?
18:37
apurvanandan[m]
When will the mentors return from Hannover?
18:38
RexOrCine
They're presently travelling back now. So their net connection is intermittent.
18:38

RexOrCine : Command Line Interface to control the camera parameters,aka DaemonCLI
18:40

It's one of the two end points to control the camera parameters, the other one being the WebUI
18:40
RexOrCine
Of course. Thanks.
18:41

The students want a picture of your rotton sandwiches. If you didn't take a photo of yourself stuffing your face earlier please take one of the next sandwich. No one will know the difference.

In fact, I think everyone's more interested in your eating habits than they are in Maker Fair... and that's the truth.

Y_G, by the way, i have fixed things on the axiom remote side and will add remote server soon, which will process data received through ttyAMC0
19:14
BAndiT1983
this would also be a big step in the direction of controlling the camera from outside
