<pie_> azonenberg, i showed up! o/ :D
<pie_> or do i kind of not cunt haha
<pie_> err, count
<azonenberg> pie_: you've been here for a while no?
<azonenberg> i was wondering if we recruited any new people
<azonenberg> or if it ended up being more of just a meetup for existing folks from here
<felix_> there were only a few people interested in this sort of stuff i didn't know before. not sure if they are interested in contributing though
<azonenberg> Yeah i figured
<azonenberg> it's an extremely niche field
<azonenberg> kinda surprised we have as big a team as we do, to be honest
<rqou> there is a guy here (who even lurks in this irc) working on some cyclone stuff
<azonenberg> Yeah i know
<azonenberg> we talked briefly
<azonenberg> no idea how active that is
<rqou> another guy here was going to poke bunnie about gowin or something
<rqou> but bunnie isn't here right now
<azonenberg> i know zilch about those parts
<azonenberg> right now it looks like greenpak is #1, psoc is fairly active but has made less progress since there's so much RE required
<azonenberg> then you're picking up coolrunner
<rqou> some "3ds scene" people made me remember again that actel exists :P
<azonenberg> and those are the main seriously active teams here atm?
<rqou> did the proasic3 backdoor password ever actually get released?
<rqou> or is it another "we did it lol"
<rqou> ?
<azonenberg> i think the latter
<rqou> some "3ds scene" people would like proasic3 to get hacked enough just to give the finger to the chinese piracy companies :P
<azonenberg> Lol
<azonenberg> i bought some pa3's a while ago
<rqou> for some reason all nintendo piracy is proasic3-powered
<azonenberg> couldnt get the dev tools to run on linux
<azonenberg> so i decapped them instead
<azonenberg> never got beyond a top metal shot as i had no real incentive to dig deeper
<rqou> because only pirates use them? :P
<azonenberg> more like, i couldnt use them
<azonenberg> so i couldn't feasibly build an open toolchain

<pie_> azonenberg, well i wouldnt know but what kind of visibility does it get at ccc? maybe people dont even know its a thing?
<pie_> though i guess people looking for stuff to look at can just look through the assembly list
<pie_> (assembly basically meaning groups)
* azonenberg has no idea
<azonenberg> i'm not there :p

<azonenberg> if you get a chance to play with it i'm very interested to see

<pie_> pointfree, saying it lke that might be a tiny bit misleading, but hm, thats interesting
<pie_> pointfree, i mean you mke it sound like it can be done with existing hardware
* qu1j0t3 notes that this is a fairly old idea
<qu1j0t3> "smart ram" is now impossible to google for, tho
<pie_> qu1j0t3, .... i can imagine
<pointfree> pie_: perhaps you could do AND and OR with an existing DRAM. Boolean NOT would require a modified DRAM.
<pie_> * i dont actually know whetheryou can or not
<pie_> not very easy to search arxiv either
<pointfree> qu1j0t3: It's like "Computational RAM" https://en.wikipedia.org/wiki/Computational_RAM but possibly much cheaper.
<pie_> gotta use diferent keyweords
<pie_> ah well there we go then
<qu1j0t3> about 15 years ago i was chatting with a guy on Usenet about doing arithmetic on memory devices. His name was Steve Richfield, he had some good ideas
<qu1j0t3> short logarithmic values
<qu1j0t3> i suppose some of this might be subsumed by GPUs now
<qu1j0t3> pointfree: yeah that's one i think i have seen
<pointfree> another by the same author https://arxiv.org/abs/1610.09603 (bulk copy and initialization)
<pie_> but yeah i think what qu1j0t3 said would make sense
<pie_> i mean either its a ne time thing or youre doing something like video no?
<pie_> *one tiem
<pie_> *time
<pointfree> Do you think "triple row activation" could be possible with an off the shelf DRAM by activating the 3 rows in rapid succession? I guess I would have to know how long it takes for those little capacitors to charge.
* pie_ mumbles about rowhammer >.>
<pointfree> (For effectively simultaneous activation)
<qu1j0t3> pie_: haha, i thought hte same
<pointfree> I'm interested in getting good performance for sparse distributed memory: https://arxiv.org/abs/1503.07469 ...and that means SIMD over sparse bitmaps.

<pointfree> qu1j0t3: thanks for the name drop.
<qu1j0t3> pointfree: he's probably disappeared though. from time to time i try to look him up.
<qu1j0t3> it was a memorable conversation to be sure
<qu1j0t3> the posts are still on Usenet somewhere. I first bumped into him as a vigorous proponent of "significance arithmetic" (ideally in hardware).
<qu1j0t3> i think his posts used the phrase "smart memory" which is probably ungoogleable as I said :/

<nats`> anywhere
<nats`> I checked that today
<nats`> sadly it's one of the only to do that
<azonenberg> nats`: they're a stock part in digikey, currently backordered though
<azonenberg> estimated low volume ship date is the 20th of next month if you want one
<nats`> ah ?N
<azonenberg> for a thousand you'd have to wait till the 30th, they'll be getting 585 by the 20th
<nats`> wait and see :)
