16:17

how you doing?
16:37
se6astian
good good
16:37
se6astian
I just emailed you about updated beta enclosure files on github
16:42
Bertl
off for a nap ... bbl
16:42

I saw the bot message last night, will look at it right now

what is the empty space behind the chip?
17:02
philippej|away
changed nick to: philippej
17:06
se6astian
the space for the image sensor socket
17:07
se6astian
which socket solution it will be is not finalized yet though
17:07
se6astian
so I just left a bit of empty space
17:22
yannick
Have you guys ever looked at video SFP module for output?
17:29
se6astian
yes
17:34
se6astian
it was actually the first choice for quite a long time
17:34
se6astian
but the common concern was that the receiver side has to be a rather large PC and that pcie cards are still expensive
17:34
se6astian
bbs dinnertime
17:41
troy_s
se6astian: Where do questions get moved to?
17:42
troy_s
se6astian: Example "solar power (?)" - I am looking for the "Ridiculous Question Ask Apertus" tag or forum to move it to.
17:52
intracube

17:52
intracube
troy_s: ^
17:55
troy_s
intracube: as always, you rock. How to move a query to ponder now?
17:55
intracube
shrugs :)
17:57
troy_s
intracube: Rock - 0.1
17:59
intracube
troy_s: idk how to move to ponder. shifting to another section like brainstorming is easy enough
18:00
troy_s
intracube: This must be fixed!!!1111!!!1111!!!111111!!!!1111
18:00
intracube
I think edit task->delete project tag->start typing brain and it should autocomplete
18:00
troy_s
Hrm. Let's try.
18:02
troy_s
intracube: only projects show up in the tags.
18:02
intracube
right, and Ponder is... something else. forum or Q&A type?
18:05
troy_s
I guess?
18:05
troy_s
No idea.
18:05
danieel
i saw in the wiki that the enclosure will have miniDP connectors... how likely is that and what is the signalling in it?
18:06
troy_s
Ponder desperately needs to be the _most_ easily found entry point.
18:07
troy_s
se6astian: Maybe you and philippej can move some links around to make Ponder the entry point?
18:07
troy_s
So that the lab can return to being lab-like and not a "me too" comment bombed dump?
18:07
philippej
problem is that people use tasks to ask questions
18:08
troy_s
danieel: how goes the camera?
18:08
philippej
or discuss anything
18:08
philippej
tasks are supposed to be tasks
18:08
philippej
:-)
18:08
troy_s
philippej: that means ponder is broken by design.
18:08
troy_s
philippej: So it needs better placement and more visibility.
18:08
philippej
probably
18:08
troy_s
95% of the cruft in the lab needs moving there
18:08
philippej
we could morel ikely won't fix those tasks
18:08
troy_s
philippej: But we can't move to ponder either!
18:09
intracube
philippej: maybe the lab landing page should be reworded?
18:09
intracube
Here you can create tasks (those are like bug reports, feature requests, ideas, etc... you name it)
18:09
troy_s
Ideas
18:09
troy_s
Brainstorming
18:09
intracube
feature requests
18:09
troy_s
All that cruft should largely be Ponder.
18:09
philippej
you are right, now that we havem ore people using it, rewording and linking to ponder might help (might :-) )
18:09
intracube
could have a separate link to ponder or some ideas section for those
18:09
intracube
yep
18:10
troy_s
I am sure it currently is sub optimal because only se6astian has posts in it
18:10
troy_s
Ponder should be "Here is where to put things"
18:10
troy_s
Nuke from space with no remorse should be policy in the lab. It is a sludge of detritus that I fear to wade through.
18:10
troy_s
Comments on the microSD vs SD thread is proof enough.
18:11
troy_s
Either that, or rename lab to "mash keyboard first before reading"
18:15
philippej
hahaa
18:15
philippej
we'll find a way don't worry
18:18
se6astian
back
18:18
se6astian
danieel: mini DP is pretty certain already
18:18
danieel
and the protocol?
18:18
se6astian
hdmi
18:19
danieel
DP even in DP++ does not do hdmi levels, you can not wire a hdmi transmitter to it directly
18:19
se6astian
troy_s, philippe: I guess we could add a link to ponder to the "welcome to the lab top panel?
18:19
se6astian
danieel: correct
18:19
philippej
reworded the home panel, better ?
18:19
se6astian
thats how herbert explained it to me
18:19
se6astian
for details I guess you have to talk to him :)
18:20
danieel
Bertl_zZ: ^^ drop me a note on how you make hdmi to dp++
18:20
se6astian
philippej: is a "queestion" something squeeky? :)
18:20
danieel
thanks se6astian
18:20
philippej
it is :-)
18:20
philippej
se6astian, just corected it :-)
18:20
se6astian
and I would like to ponder home otherwise nobody will read existin questions/answers
18:22
danieel
troy_s: had to took some design jobs to cover the expenses, so the answer is - on hold
18:22
se6astian
philippej: great!
18:23
philippej
but unfortunately it is not possible to move a task to a question
18:23
philippej
so we need to won't fix it and explain that it is a question ...
18:23
se6astian
philippej: there is another ponder point now below
18:23
se6astian
browse questions
18:23
se6astian
plus "ask questions :"
18:25
philippej
should I remove the ask question point ?
18:25
se6astian
well we have two douplets now
18:26
philippej
i's somehow intentional to guide people to ponder instead of tasks :-)
18:28
philippej
feel free to enhance it though :-)
18:32
troy_s
Agree
18:32
troy_s
It needs _much_ more prominence.
18:33
troy_s
philippej: Entirely agree. The filter flow should mysteriously direct 95% of the folks that do not read fine print to Ponder.
18:33
se6astian
prominence yes, but people will not notice it just because those points are there twice now :)
18:33
troy_s
philippej: and of course, a method to move existing discussions there would solve a tremendous amount as it would give it life.
18:33
troy_s
se6astian: It needs to have life for certain. Some peeps certainly post to the tasks looking for discussion and chatter.
18:34
se6astian
agreed
18:34
troy_s
(I am skeptical that closing solves the core issue I guess. The "Ponder" region needs active participants to pull focus.)
18:35
troy_s
I guess the reality is that as numbers grow, cultures take steering. That means how to keep gardens growing with the desirable strands of life, and constricting other strands.
18:36
troy_s
(Culture is a big thing for me obviously, and frankly I am already rather sickened by the lack of gender diversity. It makes my participation desire wane certainly.)
18:37
troy_s
(Case in point was se6astian 's post to the list and the utterly pathetic misogyny that rippled below the surface. Some of those cancerous personalities and their ilk need to be banished.)
18:40
intracube
troy_s: which thread?
18:41
troy_s
intracube: Crawl the email logs.
18:41
troy_s
intracube: It was a rather novel idea that had legs, and the toxicity already clammed it.
18:42
intracube
and why does someone's gender matter in the discussions?
18:42
intracube
except where someone is discriminated because of it
19:01
troy_s
intracube: See Foucault. It matters.
19:02
troy_s
intracube: discrimination and toxicity happens below the level of discourse. See the countless bits of interesting studies on gender for example, where graded tests results are different if the marker knows the gender of the participant.
19:02
troy_s
(Same goes for all othered folks. Race, class, etc.)
19:13

19:26
intracube
troy_s: ok, I should've said 'why -should- it matter' :)
19:27
intracube
you mentioned about lack of diversity being an issue
19:27
intracube
do we know what the ratio even is?
19:27
troy_s
Yes. 100% men.
19:27
troy_s
Lol
19:27
intracube
is often hard to tell gender/race/class from an IRC nick or mailing list name
19:28
troy_s
The sad part is that many (men) are too obsessed with maintainig power hegemonies (even if more ideologically invisible to themselves; cultural ideological blind spot if you will) than to see the _massive_ benefits of diversity.
19:29
troy_s
intracube: It is, but then you are relying on suppression.
19:29
troy_s
intracube: Should one shield identity in order to preserve the illusion of being non-other? _That_ act perpetuates the same ideological constructs.
19:30
troy_s
(Similar to Derrida's insistence that to break a duality / polemic model, one must not engage upon the negative or counter, for that reinforces the same taxonomy. Instead, the notion of a minimal third entity / axis was required.)

back now ...
20:57
Bertl
troy_s: must be a very special prism
20:58
troy_s
Bertl: Indeed. Not even beginning to discuss calibration / alignment / perceptual sharpness loss and overall light loss due to the splitter.
21:01
Bertl
no doubt that the future sensor will be some spectroscopic solution, so the use of microprisms would make sense, but beam splitting with three sensors?
21:01
Bertl
s/some/some kind/
21:01
Bertl
+of
21:01
Bertl
(just woke up :)
21:03
troy_s
Bertl: What I see in that is a
21:03
troy_s
Duh obvious way of initiating patent attacks on anyone using a mirror to implement optical imaging in small devices.
21:04
troy_s
The only non duh obvious element is that magic beam splitter
21:04
troy_s
But it gets them the patent
21:04
Bertl
I'm pretty sure lenses are already patented by some crazy company
21:04
Bertl
(similar to the one click stuff :)
21:04
troy_s
Which gets them the ability to attack any and all implementations that implement the mirror, even though they will be missing the magic splitter
21:05
troy_s
Bertl: A CCD is a beam splitter ;)
21:05
troy_s
Been donr
21:05
troy_s
Done.
21:05
troy_s
Splitters just never work because of the tolerances. Even a CCD I am sure has issues as the light passes through.
21:06
troy_s
For future patent trolls though
21:06
troy_s
I would like to state that Bertl and I have discussed a spectral sensor dated this date
21:06
troy_s
Thereby declaring such a thing as prior art
21:07
troy_s
(Used to escape the pre-baked spectral data issue surrounding tri-light sensors)
21:07
troy_s
Bertl: Are you aware of anything even remotely close to a spectral sensor?
21:08
troy_s
Bertl: Last I checked the most rudimentary spectral renderer needs to trade the tricolor three floats of RGB in for 40 floats.
21:08
troy_s
(Minimum)
21:08
comradekingu

21:08

21:08
troy_s
Which implies a 40 unit sensor per photosite.
21:09
Bertl
which isn't that far fetched
21:09
Bertl
just think trading a 40 megapixel sensor (monochrome) against a 1 megapixel spectral sensor :)
21:10
troy_s
To much citing issue
21:10
troy_s
Too
21:10
troy_s
Unless via a CCD stack
21:11
Bertl
I'm pretty sure once quantum dots are a standard element for optical devices, such 3D stacks will become a commodity
21:11
Bertl
there is a different approach to the problem though, from the physics PoV
21:12
troy_s
Bertl: make no mistake, if there were a method to get a spectral image it would be a HUGE deal in cinema work
21:12
troy_s
Guaranteed uptake with post houses immediately
21:12
Bertl
as every photon has a specific energy, converting and sampling that energy on a per event basis would eliminate the need for several sensitive elements
21:13
troy_s
Explain?
21:13
Bertl
this is what is done in detectors for PET for example
21:15
Bertl
so energy of the photon is equivalent to the frequency
21:15
Bertl
higher frequency -> higher energy
21:15
Bertl
measuring the energy of a single photon, will give you the exact wavelength
21:16
Bertl
counting events based on the energy (in some kind of bins) would result in spectral information
21:16
Bertl
(and extremely good sensitivity of course :)
21:18
Bertl
one of the major problems nowadays is that single photons are not that easy to detect, but technology advances and especially medical imaging requires new solutions
