11:44 | joy_ | hello, I will be doing the 3rd task of VHDL challenge that is high speed link...just to make sure what to do: I need to make a data serialiser and deserialiser and check by PRNGs
| |
11:45 | joy_ | Can anyone please explain what is link training and how to implement them.

15:49 | anuejn | i build a small tool for playing with pixelshaders for debayering beta footage: https://anuejn.github.io/batic/ feel free to hack :)
| |
15:51 | anuejn | just hack on the code. sliders are created automatically and the preview gets rerendered on the fly
| |
15:51 | Rex0r | Link leads to a blank page.
| |
15:55 | anuejn | it just loads a big (24M) raw16 page
| |
15:55 | anuejn | *image. that takes quite some time
| |
15:56 | Bertl_oO | works here
| |
15:57 | Bertl_oO | very interesting moire effects when you zoom in/out though
| |
15:58 | anuejn | yeah thats related to the way, the browser scales the canvas. wasnt able to fix this yet
| |
15:59 | Bertl_oO | maybe only allow specific magnifications?
| |
16:00 | anuejn | mmh. meh.. maybe
| |
16:07 | Bertl_oO | hmm, why do I also get a pattern when I zoom in to the pixel level?
| |
16:11 | anuejn | i dont no either
| |
16:11 | anuejn | but thats really bad
| |
16:11 | Bertl_oO | I think there is a problem with the order of operations
| |
16:12 | Bertl_oO | i.e. the scaling for the zoom should apply after a fixed size debayering
| |
16:12 | Bertl_oO | but actually it seems to be the other way round, i.e. the scaling controls which bayer 'sensel' are sampled
| |
16:13 | Bertl_oO | note that the scaling/zoom is not something you need in a real world application except for specific transformations
| |
16:14 | Bertl_oO | e.g. going from 2160p 'raw' to 1080p 'debayered'
| |
16:14 | anuejn | the scaling is done after the debayering
| |
16:14 | anuejn | everython is rendered to a fixed size opengl canvas and than this is scaled by the browser
| |
16:15 | seku_ | left the channel | |
16:15 | Bertl_oO | okay, then the debayering algorithm is really bad :)
| |
16:16 | anuejn | you are right but for i think, that it is quite handy for experementing to be able to look at details
| |
16:16 | anuejn | of course
| |
16:16 | Bertl_oO | yes, I agree that you want to 'zoom in' on the result
| |
16:16 | anuejn | the algorithm is the most naive approach i could come up with
| |
16:16 | anuejn | but its okay for demoing the tool and to start with
| |
16:17 | Bertl_oO | fair enough
| |
16:18 | Bertl_oO | so how does it work? get_color_value() is called with a position for the 'to be calculated' pixel, right?
| |
16:18 | Bertl_oO | the pos value can be assumed to be integers in what range?
| |
16:19 | anuejn | 0 to 4096 or 3072 for the example image
| |
16:20 | Bertl_oO | the sensel data can be retrieved with get_intensity() I presume, which also takes a two integer pos argument, yes?
| |
16:20 | anuejn | yes
| |
16:22 | Guillaume_Chooks | left the channel | |
16:23 | Bertl_oO | why is it 0 to 4096 or 3072 and not 0 to 4095/3071 ?
| |
16:26 | Bertl_oO | and what is the float range of get_intensity()?
| |
16:26 | anuejn | oh i failed of course you are right
| |
16:33 | Bertl_oO | hmm, I don't think I get how this works ... here is my trivial code I tested:
| |
16:33 | Bertl_oO | https://pastebin.com/raw/ZdLiyWe8
| |
16:34 | Bertl_oO | for whatever reason this gives me a dark-ish gray image with colorful patterns when you zoom in
| |
16:35 | Bertl_oO | ah, sorry, my fault, I forgot to multiply the coordinates by two again
| |
16:36 | Bertl_oO | okay, that seems to work and gets rid of the patterns
| |
16:36 | Bertl_oO | int x = (pos.x/2)*2;
| |
16:36 | Bertl_oO | int y = (pos.y/2)*2;
| |
16:44 | Bertl_oO | or probably more efficient:
| |
16:44 | Bertl_oO | int x = pos.x & ~1;
| |
16:44 | Bertl_oO | int y = pos.y & ~1;
| |
17:27 | Bertl_oO | here a 'high resolution' version:
| |
17:27 | Bertl_oO | https://pastebin.com/raw/MCaKp563
| |
17:27 | Bertl_oO | btw, the error output does not disappear when everything is fine, which is a little confusing :)
| |
17:50 | se6astian | IRC meeting in 10 minutes
| |
17:53 | se6astian | anuejn: very cool work with https://anuejn.github.io/batic/
| |
17:54 | anuejn | thx :)
| |
17:54 | davidak[m] | hello everyone
| |
17:54 | BAndiT1983|away | changed nick to: BAndiT1983
| |
17:56 | anuejn | btw. what is the license of the images in http://files.apertus.org/AXIOM-Beta/snapshots ?
| |
18:00 | se6astian | hi davidak[m]
| |
18:01 | se6astian | anuejn: good point, we do not have a license file in there to specify it
| |
18:01 | se6astian | but I would say its creative commons
| |
18:01 | se6astian | meeting time!
| |
18:02 | anuejn | whom is the author?
| |
18:02 | se6astian | I think I took that picture
| |
18:02 | comradekingu | "creative commons" needs to be specified by the licences on offer from them
| |
18:03 | se6astian | for the IRC meeting please pm me now if you have a topic to report/discuss
| |
18:03 | se6astian | and I will put the topics in order
| |
18:03 | se6astian | www.apertus.org says "Website content available under CC-BY 4.0 International license"
| |
18:04 | comradekingu | The default one for Apertus media is https://creativecommons.org/licenses/by-sa/4.0/
| |
18:06 | se6astian | anyone with topics for todays meeting?
| |
18:07 | se6astian | I will report in the meantime
| |
18:07 | se6astian | 1. GSoC org application has been handed in successfully last week
| |
18:07 | se6astian | as we already participated last year there is a good chance we will be accepted again
| |
18:07 | se6astian | but we can only be 100% sure once we get approved
| |
18:08 | se6astian | that will be released on Feb 12th
| |
18:09 | se6astian | timeline: https://developers.google.com/open-source/gsoc/timeline
| |
18:09 | se6astian | 2. the AXIOM hardware assembly office has moved
| |
18:09 | se6astian | we are now at an industrial manufacturing/fab lab/coworking space at : https://factoryhub.at/
| |
18:10 | se6astian | today is our first day "in business" here
| |
18:10 | se6astian | I am writing from our new office desks actually :)
| |
18:10 | se6astian | moving all the machines and equipment was quite a challenge in the last week
| |
18:10 | se6astian | here are some impressions: https://cloud.gerade.org/index.php/apps/gallery/s/PGhonMwtS6m9IbE#20180129_111050.jpg
| |
18:10 | se6astian | sorry for potato cellphone image quality
| |
18:11 | se6astian | we have all machines set up and operational again at the new space and hope to resume hardware production next week
| |
18:11 | Rex0r | Present.
| |
18:12 | Bertl_oO | nice
| |
18:13 | se6astian | the focus is more on sharing equipment, machines, collaborating
| |
18:13 | se6astian | so very much in line with our spirit
| |
18:13 | se6astian | but I am sure it will bring some new challenges to solve
| |
18:14 | se6astian | 3. the website has seen some sections being reworked
| |
18:14 | se6astian | https://www.apertus.org/ has a new footer
| |
18:14 | se6astian | https://www.apertus.org/mission-statement is new
| |
18:15 | se6astian | and contains a summarized but very essential overview of our projects "maniphesto"
| |
18:15 | comradekingu | I think "ethos" sounds better than "mission-statement"
| |
18:15 | se6astian | new home/landing page is in the works plus some other subpages
| |
18:16 | se6astian | comradekingu: noted
| |
18:17 | se6astian | 4. https://lab.apertus.org/ is seeing increased spam attacks recently
| |
18:17 | se6astian | but as we have an all new phabricator already set up and ready at http://lab2.apertus.org/
| |
18:18 | se6astian | we will soon make a full switch rather than implement spam countermeasures on the old system
| |
18:18 | BAndiT1983 | are there new measures in the newer one?
| |
18:18 | comradekingu | is a new login needed?
| |
18:18 | se6astian | last invitation to play around with http://lab2.apertus.org/ and try to push the system and discover bugs before we switch over
| |
18:18 | davidak[m] | is there a ticket for the new footer? i have broken layout in chromium 64
| |
18:19 | se6astian | BAndiT1983: Its a much newer release so if we still see spam accounts we can deal with them on the new system rather than the outdated one
| |
18:19 | se6astian | comradekingu: accounts and content were already migrated
| |
18:19 | se6astian | but will be overwritten once again from lab.apertus.org once we make the production switch
| |
18:19 | BAndiT1983 | github login for lab2 is not working yet, so i will wait till the switch
| |
18:19 | se6astian | davidak[m]: please create a lab ticket in the old phabricator
| |
18:20 | se6astian | BAndiT1983: yes the github auth is unfortunately broken with missmatching urls
| |
18:21 | se6astian | ok thats it from my side from the top of my head
| |
18:21 | Rex0r | We do use the word ethos frequently in other areas of the site/Wiki, mission statement tends to be a universally understood heading where website structure or introduction materials are concerned. For instance we have a page that details the 'open source ethos' and in this sense 'ethos' is referred to in documentation in this sense. In other words, deviating away from the term mission statement may cause confusion in some of
| |
18:21 | Rex0r | the project's copy.
| |
18:21 | se6astian | anything else to share/discuss while we are all together, now is the time
| |
18:24 | comradekingu | Is the red thing fixed?
| |
18:25 | se6astian | right, then I conclude todays IRC meeting and schedule the next one for Monday in two weeks
| |
18:25 | se6astian | I will add the meeting minutes to the wiki in the coming days
| |
18:25 | se6astian | comradekingu: define "red thing"
| |
18:26 | comradekingu | The red artifact on the videofeed of the CCC protptype
| |
18:26 | se6astian | heard no reports of that so far
| |
18:27 | comradekingu | Ok. If you upgrade to Nextcloud 13 (or 14 soon) we can use Talk for videochat meetings
| |
18:28 | comradekingu | A fitting way to display the uses of apertus video
| |
18:29 | comradekingu | I have found it to tidy up my desk immensely
| |
18:29 | davidak[m] | comradekingu: felix_ knows the limitations of the SDI module
| |
18:29 | davidak[m] | and will work on that
| |
18:34 | davidak[m] | se6astian: https://lab.apertus.org/T918
| |
18:35 | BAndiT1983 | davidak[m], is the page zoomed somehow? what is your screen resolution?
| |
18:36 | davidak[m] | no zoom
| |
18:36 | davidak[m] | 1366x768
| |
18:37 | illwieckz | left the channel | |
18:37 | BAndiT1983 | pretty much what i've expected, it seems that we need to adjust the media queries, so the elements are moved/wrapped earlier
| |
18:38 | davidak[m] | i think there is enough space around the links
| |
18:40 | BAndiT1983 | the prototype worked more or less for mobiles and hd ready screens, but current implementation is not doing the right switch
| |
18:40 | davidak[m] | when i make the window smaller it get's even worse
| |
18:40 | BAndiT1983 | tried it already, the links disapper, have to investigate
| |
18:40 | BAndiT1983 | *disappear
| |
18:41 | BAndiT1983 | but i remember that se6astian has added some workaround to bypass drupal layouting, maybe it's breaking the switch
| |
18:45 | BAndiT1983 | se6astian, we need to move the footer out of the main container
| |
18:45 | BAndiT1983 | then the wrap is working correctly, also when shrinking
| |
18:51 | illwieckz | joined the channel | |
19:01 | davidak[m] | se6astian: here are some improvements for the mission statement https://hackmd.io/KYdgzAjArARmAsBaMBOGAGR8Ac1EwCZ4A2RYAEyigggENhQEg===
| |
19:03 | davidak[m] | should i create a ticket or do you want to update it directly?
| |
19:07 | davidak[m] | i really like that the picture on the page is made with a beta :)

19:10 | Rex0r | Not sure about the empowering. Expectations can't be true or false, but they can be raised or lowered. So the appropriate form for that message would be "raise expectations unduly"... but then, the whole concept of raising expectations is open to a lot of interpretation, so, not sure.
| |
19:11 | davidak[m] | you may be right
| |
19:12 | Rex0r | And like you say there are time frames for development involved, so...
| |
19:12 | davidak[m] | but you know some marketing is very aggresive with raising expectations and we shouldn't do that and i think we didnÄt in the past
| |
19:14 | davidak[m] | >We will not exploit the users of the tools we develop.
| |
19:14 | davidak[m] | this probaply includes not adding limitations to products to sell a more expensive version
| |
19:15 | davidak[m] | but we could add that becouse it's often the case with cameras
| |
19:18 | Rex0r | This is the thing with the word marketing. It's really loaded, and what springs to people's minds are things like the Bill Hicks sentiments. But he was talking about the 1980's, he never met people like us. So marketing is like a gun, and it's the consciousness behind the gun that pulls the trigger. There's not much we can do about this but unfortunately the marketplace and those operating inside it give the concept of
| |
19:18 | Rex0r | 'marketing' a bad name I guess.
| |
19:21 | BAndiT1983 | changed nick to: BAndiT1983|away
| |
19:21 | Rex0r | Luckily the community/team is pretty conscientious on all fronts. We don't need to foster a false sense of security by coming up with a slogan like "Don't be evil". This project is the real deal.
| |
19:23 | davidak[m] | sure, but we could differentiate "bad marketing" with our marketing so a new visitor understand what we stand for
| |
19:23 | davidak[m] | it's a big thing that cameras have technical limitations
| |
19:24 | davidak[m] | like point and shoot and DSLR can't record more than 30 minute videos
| |
19:24 | davidak[m] | and point and shoot can't capture RAW
| |
19:24 | davidak[m] | ...
| |
19:25 | davidak[m] | i think that is a good example people would understand
| |
19:41 | mithro | Bertl_oO: ping?
| |
19:41 | Rex0r | You might be onto something. eg. why mention marketing in the first place. Have improved that section.
