01:00 katsmeow-afk Tegra X1 packs in an eight-core 64-bit CPU and 256 GPU cores.
01:26 katsmeow-afk fascinating, i can't put down this book on antigravity
02:20 rue_house I'm back
02:20 rue_house for a bit, I ahve to go to bed
02:20 rue_house a gpu flop isn't the same as a normal cpu flop, vector processors
02:21 tsmeow-afk is wondering how you can get data into a single chip fast enoug for it to be processed by the 256 1 teraflop machine to proces
02:21 katsmeow-afk Tegra X1 packs in an eight-core 64-bit CPU
02:21 rue_house tahts where 3d rendering comes in
02:21 rue_house limited scene description and 60+ renderings/sec
02:22 rue_house on high resolution displays
02:22 rue_house maybe I should implement my ai on a gpu...
02:22 rue_house ?
02:22 katsmeow-afk i think it needs over 1024 pins just for the 8 cpus
02:22 rue_house the io isn't so bad
02:22 rue_house they dump in the polygons and a viewpoint
02:23 rue_house the card renders the scene at whatever viewpoint the camera is at
02:23 rue_house the video cards have gigs of ram
02:23 katsmeow-afk so this is only about generating one anime screen?
02:23 rue_house people are finding other uses for them
02:24 rue_house bitcoin mining is only effeciently done on the graphcis cards specifically made for bitcoin mining
02:24 rue_house confused yet?
02:24 katsmeow-afk the Ai we don't know about yet is sneaking up it's horsepower by making humans think they need these superchips for watching youtube?!
02:25 rue_house well, considering I'm sure that given the right alg current computers are fast enough, one of those video processors would more than do it
02:25 rue_house 4G of ram, how many neurons in the human brain?
02:25 katsmeow-afk you need more than 4 gig of ram just to store the *movies* about Ai
02:26 katsmeow-afk wikipedia is ~16gigabytes, not including the images on the pages
02:26 rue_house how many neurons on the human brain...
02:26 rue_house mroe than 4G?
02:26 katsmeow-afk i lost count
02:27 rue_house average human brain has about 100 billion neurons (or nerve c
02:27 katsmeow-afk it's not about how many, it's about how many are in use, and for what
02:27 rue_house so, 100G
02:27 rue_house indeed, but I'm talking ugly equiv
02:28 katsmeow-afk ok
02:28 rue_house so at 100G there could be direct emulation
02:28 katsmeow-afk so a single core p4 and a 250gig hd?
02:36 katsmeow-afk transmophers?
02:36 katsmeow-afk transmorphers?
02:41 katsmeow-afk drat, Hal (2013) is anime too
02:45 rue_house hmm
02:47 katsmeow-afk the problem i am having is that a true powerful Ai would be running a george's_cows subroutine, and tick them off as dead after so many seconds have passd, because cows don't live that long, and such an ai wouldn't askGeorge in 20 years how his cows are
02:48 katsmeow-afk but existing "advanced" programming languages don't allow for creating and controlling such subroutines, AND knowing the subroutine exists, and being able to query it
02:49 rue_house yea, you cant run a std os
02:49 rue_house goodnight
02:49 katsmeow-afk gnite
17:28 katsmeow the guy developing the Mill cpu emailed me , asked me questions, and invited me to their developer forum
17:29 katsmeow but he said there was no prize for having figured it out
18:26 rue_house just this morning I was looking at a project called grbl, which is a gcode interpreting arduino software
18:26 rue_house for stepper motors
18:26 rue_house https://github.com/grbl/grbl
18:36 Tom_itx i've heard of grbl
18:47 katsmeow i'm sorry, what's garbled?
20:59 Tom_itx rue_house, you gonna do something with it?
21:42 rue_house maybe
22:45 katsmeow note to self: thise tiny bristles on the dremel wire brush are *tiny* but can hurt after they been in your skin for a couple days
22:47 rue_house *ouch*
22:52 katsmeow seems i went past what they do with the Mill, and into what they want to do but cannot
22:52 rue_house hmm
22:52 rue_house you see what I posted?
22:52 rue_house did it make sense
22:53 rue_house I'm 'fixing' a wav playing library for the arduino
22:53 katsmeow err, umm,, when?
22:53 rue_house <rue_house> the sample rate is played at 62Khz, 31Khz, or 20.8khz depending on what the sample rate really is
22:53 rue_house <rue_house> nowonder the pitch sounds screwed
22:53 rue_house <rue_house> the volume is done by cutting off the offending peaks of the sample
22:53 rue_house that grbl project
22:53 katsmeow you did not say that in here, so i did not hear it
22:53 rue_house they dont preload the buffers before they start playing the wav
22:54 rue_house rue_house> https://github.com/grbl/grbl
22:54 rue_house ^^^^
22:54 rue_house that is an arduino gcode interpreter for stepper based cnc machines
22:54 katsmeow why are you playing .wav into your stepper based cnc machines?
22:55 rue_house no, I'm on two unrelated topics at once
22:55 katsmeow now i know why it's gbld
22:55 rue_house dear god, they have the checks if a buffer is empty in another interrupt
22:55 rue_house of the same timer as the pcm
22:56 rue_house they they bodged for the sample rate timer
22:56 rue_house someone shoot me?
22:56 katsmeow If you don't mind me asking, who are you in real life and what
22:56 katsmeow does whoever pays you think they are buying? Your mails remind me somewhat
22:56 katsmeow of Paul Clayton, who has an extraordinarily encyclopedic knowledge for
22:56 katsmeow someone who doesn't work in the field. And if you know Jeri then you are
22:56 katsmeow at least somewhat connected.
22:56 katsmeow i *wish* i knew Jeri
22:56 rue_house heh
22:57 katsmeow i wrote an email, said hi, she said i was an ahng, i was like fuuuuuuuuuuuucccccck, nvm
22:57 rue_house arg, I can only put the buffer refill code in an interrupt
22:59 rue_house ooooh AND if they cant fill the buffer once more completely cause the file is too short, they just drop those last samples of the file
22:59 rue_house FFFFFFFFFFFFFFFFFFFFFFFFFFFF
23:00 rue_house I think it loses two buffers of data at the start of the file too
23:00 rue_house ammater a fact, I think it plays two buffers of garbage instead
23:01 katsmeow they call that "original programming" ?
23:01 rue_house the start playing code says the 2 buffers are full, loads no data into them, and starts the play routine
23:02 katsmeow why?
23:03 rue_house WHY INDEED!
23:03 rue_house they *could* have just said they were empty, the code would automatically reload them
23:03 rue_house this is such amazingly bad code
23:05 katsmeow "not my fault, i was out to lunch when that was written"
23:05 rue_house heh
23:05 rue_house I can tell two people were at it
23:05 rue_house one person used TRUE and FALSE on the booleans, the other person used 1, 0 and used them as array indexes
23:06 rue_house SAME BOONLEAN
23:06 katsmeow arg
23:07 rue_house I thought I wouldn't have to write anything from scratch if I used arduino
23:07 rue_house it took me more time to learn that I did than if I just had at the start
23:08 katsmeow it's an avr, of course yu haveto write code for it
23:08 rue_house I didn't think the arduino libraries would be this bad
23:09 rue_house I dont think I'v EVER seen code this untrue to what its supposed to do
23:09 katsmeow "it's microsoft, they been writing operating systems for 30 years, of course it works ri.W$&$%^@$BLLEEPPBLOOP <bluescreen>"
23:09 rue_house Returns
23:09 rue_house the first byte of incoming data available (or -1 if no data is available)
23:10 rue_house "so was that -1 from the file or the error?"
23:11 katsmeow yeas!
23:13 rue_house aaaah, I see why they aren't using the default arduino SD card library, IT CAN ONLY HANDLE TEXT
23:14 katsmeow case of the free code being worth everything you paid for it?
23:15 katsmeow brb
23:15 rue_house less , actually
23:16 rue_house cause, I'm still paying
23:17 rue_house all this code does is make noise roughly based on a wav file
23:18 rue_house its ok this file library cant handle binary data, it explains why they return -1 on end of file
23:18 rue_house there is another library that does handle binary data
23:18 rue_house this is fine
23:26 katsmeow k
23:28 katsmeow ok,,,,,,

23:31 katsmeow Bulbs: Is this auction for 1 or 2 or 10 bulbs ?
23:31 katsmeow memotronics_llc : The number of bulbs included is shown in the title and in the "Items Per Lot". If no number is given, then the auction is for a single bulb.
23:31 katsmeow Most halogen bulbs are sold individually. Most (but not all) other miniature bulbs are sold in boxes of 10
23:31 katsmeow Bulbs: Will this work in my car ?
23:31 katsmeow memotronics_llc : We don't know.

23:48 katsmeow s&h : $109.99
23:52 rue_bed kat, to harden drillrod, do you know if its a fast or slow cooling cycle?
23:52 rue_bed sounds like ebay mixed up their database
23:52 rue_bed hmm, $3 a mouse
23:53 katsmeow yeas, but laser isn't under fingertips like you wold expect the mouse to track from
23:53 katsmeow and, you hate that color
23:53 rue_bed I neversaid anything about colour, I'm sure of it
23:54 rue_bed need to make dies to drawing plastic filament
23:54 rue_bed need a few special tapered bits for the lead in/out
23:54 katsmeow they are pink, like the shaft couplers on the pcb driller i destroyed because the shaft couplers were pink
23:55 rue_bed I'm pretty sure I commented on concerns about the ridgidity, not the colour
23:55 katsmeow no, the whole channel was sure it was about the color
23:56 rue_bed and you answered that the rigidity was fine and I said ok
23:56 katsmeow you have referred to it as "anti theft", because no one would have anything that color
23:56 rue_bed yes, and at work it is
23:56 rue_bed since I used the neon colour on my tools, none of them have dissapeared
23:57 katsmeow so, i took the thing outside, and cut it apart witht he cutting torch
23:57 rue_bed I was losing 2-3 per year
23:58 rue_bed so this morning we got a call from the police on vancouver island
23:58 rue_bed asked if we were missing a saw
23:58 rue_bed turns out some guys raided one of out storage yards, filled a truck with cabtire cable
23:59 rue_bed our
23:59 rue_bed turned up on the island before we even noticed
23:59 katsmeow cabtire cable?
23:59 rue_bed prolly 1200lbs of cable
23:59 rue_bed the rubber coated stuff
23:59 rue_bed we have to go over there and get it all back
