<digshadow> rqou: sem is offline right onw
<digshadow> its a bit awkward to use right now
<digshadow> and last week I lent out my vacuum pump to another sem
<azonenberg> digshadow: meanwhile i'm finally starting to get sem/fib access

<openfpga-github> openfpga/master c014b81 Andrew Zonenberg: IOB now loads timing data from JSON correctly. gp4tchar now operates in "append" mode, adding timing data to existing file if present
<azonenberg> also, i really have to optimize my test drive
<azonenberg> right now i have 3200 JTAG transactions for every single delay measurement (100 averages, 32 taps eacH)
<azonenberg> if i moved the delay tap logic into the FPGA, i could cut that down to 100 jtag transfers each

<openfpga-github> openfpga/master 517fb32 Andrew Zonenberg: Now characterizing LUTs across 3.3V voltage range
<azonenberg> Ok, that's enough for tonight
<azonenberg> I have LUT, cross-connection, and I/O cell rising-edge-only propagation data
<azonenberg> before i do anything else i need to massively optimize my data collection so it doesn't take 5 seconds or so per measurement
<azonenberg> And add falling-edge propagation delay stuff
<azonenberg> once i get that done i can start working on setup/hold time measurements

<rqou> aaargh photo editing takes absolutely forever
<lain> rqou: what are you editing?
<rqou> don't worry about it :P
<lain> lol
<lain> personally I use lightroom
<rqou> i am using lightroom
<lain> ah
<lain> WELL THEN
<rqou> (2015 though because my CC subscription is a bit borked)
<lain> yeah LR didn't handle the CC transition well
<rqou> no, this is "CC 2015"
<lain> oh
<lain> lol
<rqou> i'm also not editing for 100% photorealistic :P
<lain> photorealistic is boring
<pie_> hes editing his latest porn shoot
<rqou> some might call it that :P :P
<lain> photoshop is better when you need to enlarge things
<rqou> i will ABSOLUTELY NOT be breaking out PS this time
<lain> hahaha
<rqou> my friends are already mad at me how late this is
<rqou> aaaargh i think i will just copypasta my develop settings across the whole batch YOLO
<lain> I like the "sync" feature
<rqou> i mean, these were all shot in the same lighting...
<lain> I mean, if they're all shot under the same conditi... yeah
<lain> it should at least be a good baseline, maybe slight tweaks per image
<rqou> i normally start with auto WB, auto tone as a baseline, but that doesn't quite work in this case
* lain nods
<rqou> not because the lighting is challenging, but because the desired output is :P
<lain> when the colours don't work out for me I just convert the to b&w lolol
<rqou> fine i will tell you what i'm working on
<rqou> here is a single pic from the batch: http://i.imgur.com/WsUrPZS.jpg
<rqou> so yeah :P
<lain> awesome
<pie_> woa woa woa
<pie_> what is ths fleshy nonsense
<rqou> heh, this is actually just a random stranger :P
<rqou> my friend is in some of the other photos though
<pie_> im joking tho
<pie_> pre-T cool
<rqou> also LR is pretty slow
<rqou> (or my laptop that i'm doing this on is just slow)
<pie_> you guys know anything about setting up compute cluster
<rqou> ugh for the future i really need something more precise than "eyeball it ETTR" :P
m_t has quit [Quit: Leaving]
<lain> rqou: tbh I've never bothered with ETTR
<lain> it's hard to do anyway because I'm not aware of any camera that shows you a real histogram
<lain> the histogram is cooked
<rqou> i can get zebras with magic lantern firmware
<rqou> but idk how real the histograms are
<lain> oh ML, probably the only way to get an accurate histo, yeah
<rqou> heh now that my eyes have adapted to the deliberate green tint and reduced contrast, the originals look totally weird
<lain> lol I hate that
<lain> also like, you'll be slowly tinting an image and you wind up wayyyy overdoing it because your eyes keep adjusting :x
<rqou> i wonder how much of nier automata's development time was just spent on shaders? :P
<lain> lol
<rqou> and meanwhile my friends are all "why does doing photo editing take so long?"
<rqou> although the biggest part of that is actually procrastination :P
<rqou> aaand after all this work i have to output overcompressed .jpgs for one of the evil blue websites
<rqou> (the one with the fake news, not the one with the nazis :P )
<rqou> er actually wait there are three major blue websites i can think of, not two
<rqou> the one with fake news, the one with nazis, and the one that is always spamming your contacts
<rqou> wow fb's album uploader script is garbage
<rqou> it's triggered the "hung script" dialog three times already
<jn__> must make a torrent ;P
<rqou> do you actually want the raws?
<rqou> yeah now it's just triggering the "hung script" dialog every several seconds
<lain> lol
<rqou> something like 10 times already
<rqou> it clearly isn't designed for you to bulk submit over a hundred photos at once
<rqou> i assume you're only supposed to periodically upload selfies and food pics
<rqou> not batch upload
<rqou> i swear this is somehow slower than just uploading one single file with the same combined total size
<rqou> why is uploading hard?
<lain> lool
<rqou> hey, plls r hard
<rqou> btw my build of icepll is also busted and i haven't had a chance to investigate why
<rqou> or whether i need to yell at clifford to fix it
<rqou> anyways, i finished the photos that my friends were about to murder me about
<rqou> sleep time
<pie_> oh god kernel mailing lists are hard to read
<pie_> these people are hardcore
<jn__> and lkml.org is down :(
<pie_> err, i mean i was just reading the thread i linked
<pie_> (for no specific reason)
<jn__> lkml.org is not really easier to read (it delivers the same mails, after all) but it's easier to navigate because it has a fancy side bar
<pie_> i meant heard to read because ofthe contents
<pie_> not because of the format
<pie_> though i guess that might not be the best either

<azonenberg> pie_: and i'm using json for storage of results
<azonenberg> what i meant was
<azonenberg> right now i have like 3200 jtag transactions per measurement
<azonenberg> i need to optimize that :p
<azonenberg> gonna move one of the inner loops to hardware rather than having the PC app lock-step it over jtag

<pie_> wait i thought rqou was doing this?
<pie_> "After I reported a few bugs in their datasheets they decided to skip the middleman and give me direct access to the engineer who writes their documentation so that I can get faster responses. " thats awesome :)
<pie_> huh this is a year old eh

<qu1j0t3> is 5 gen supported now?
* cyrozap thinks they "fell of a truck"
<cyrozap> The same seller also has XC7K410T's for $400 each.
<pie_> is fpga counterfeiting a thing
<lain> some people will sell pulled & reballed fpgas as new
<cyrozap> Possibly, but this seller has a flawless rating, so my guess is they're selling either stolen goods or ones that didn't pass all the QA checks.
<cyrozap> Ah, yeah, that might be it, too.
<lain> also I suspect people buying high-end FPGAs off ebay aren't likely to do thorough testing ;)
<lain> but if they work at all that's a good sign :P
<lain> I mean, at least that means they didn't just laser a different chip to say it's whatever fpga (which is common in counterfeiting)
<lain> hm. you know, I never really thought about it, but I wonder if that's one of the reasons intel and other companies use goofy-ass bga footprints - if each chip has a unique footprint, it'd be a lot more effort to counterfeit
<lain> vs. stuff using a typical full grid array where it could be any ol' 1mm pitch 400-ball chip, or etc
<pie_> huh.

<zino> I wish Motorola had done that. Finding a non-fake 68060 is hard.
<rqou> how fake is fake? totally different part or something like "hitachi's version, not an original motorola version?"
<rqou> also, i thought 68ks were in a unique giant dip package?

<zino> Most of them are low-cost 060 lacking MMU and FPU relasered to be high-end 060s of a later revision. But some are re-labeled 040s-
<zino> They come mostly in PGA-package with the same layout as 040.
