00:51 rue_shop2 -
00:52 rue_shop2 we tried to cast the communicators, but I think I poured too fast and the mold came apart
00:52 rue_shop2 the lawn got the majority of the metal
00:52 rue_shop2 but the impression hadn't come out too good anyhow, so a retry was in order from the start
00:53 y23470919 is unsure if she shuld be hearing
00:53 rue_shop2 we made more casting sand meaning that the casting of anything may no longer require putting chunks of wood into all the void spaces of the mold
00:53 rue_shop2 ?
00:53 rue_shop2 R410 refrigerant?
00:53 any23470919 no, the casting
00:54 any23470919 ibeenhere ahours, but zhanx came in nd you told him immediately
00:55 rue_shop2 ok I think your working on making a heat pump
00:55 rue_shop2 I did?
00:56 rue_shop2 I asked what was up when I got home, then I fell asleep till 6
00:56 rue_shop2 when moon came over and we did some aluminum casting and now its now
00:56 rue_shop2 I just read your work
00:56 rue_shop2 may I suggest more parallel runs to keep the temp down?
00:57 any23470919 well, i was looking at freons for two projects, one was mashing on pistons to make rotary motion,, the other was to be a fridge of ac
00:57 rue_shop2 I'm not 100% sure what your up to
00:57 any23470919 or ac
00:57 rue_shop2 ah
00:58 any23470919 cannot keep the temp down if you are looking for a pressure ,, or cannot hold down the exhaust pressure/temperature on a cots compressor
00:58 any23470919 window ac unit using r-22 (which is going to be impossible to find soon) , at the compressor, puts out over 212F and 100's of psi
00:59 any23470919 i cannot run that nto a plastic boiler tube
00:59 any23470919 cheaply
01:02 rue_house use brine and an exchanger
01:04 any23470919 the salt in brine attacks everything, specially hot
01:04 rue_house even plastic
01:04 rue_house ?
01:05 rue_house I suppose that makes the exchanger a challange
01:05 rue_house whats propane? R24?
01:05 any23470919 490
01:06 any23470919 290
01:06 rue_house so I used the old sand blasting sand to make the new casting sand
01:07 rue_house which means the sand blaster has the new sand it needs
01:07 rue_house and I have more casting sand
01:08 rue_house oh so late for supper
01:10 zhanx ok missed part of this as my net dropped and I am a code loop in the brain right now
01:10 rue_house you got the bit where I said I would never look all that up again, right?
01:10 any23470919 no
01:11 zhanx yep
01:11 zhanx bookmarked it all rue
01:11 rue_house it was with z last night, picking 3d printer parts
01:11 zhanx taking 1000 lines of code making it 250
01:11 zhanx :D

01:22 any23470919 finally got two EQ set up on the aptop, so with earbuds, it sounds like the bass guitar and stacks are right there and determined to be heard
01:24 any23470919 got the 15hz maxed at +15, got the 60hz down 15 on one and down 5 on the other
01:25 any23470919 170 and 330 near the -15
01:25 any23470919 at least with these earbuds, the bass sound is flat
01:25 any23470919 i'm sure it wold be killing my 15' woofers
01:33 any23470919 ok, i leave so you guys can talk . nite
01:48 rue_house I doubt will ship to canada
01:49 zhanx code before I optimized 21,408 code after 15,156
01:49 zhanx avr dude is uploading now
01:50 rue_house find any good bugs?
01:50 zhanx lots
01:51 rue_house uninitialized, unused and forgotten variables?
01:53 zhanx and tons and if statements
01:53 zhanx not nested
02:00 rue_house whats the code?
02:13 zhanx code for my touch screen menu
02:13 zhanx JOOS
02:13 zhanx JJON
02:14 zhanx some like that i found
02:14 zhanx need to put my #ifdef DEBUG back in now
02:15 zhanx debounce the touch sceen on the right timer so i can use it i tigger the watchdog timer
02:16 zhanx next is by screen touch areas etc
02:24 rue_bed java?
02:25 zhanx c
02:28 rue_bed ah, they had the same if I few times over in a row?
02:28 rue_bed I seen a few people do that
10:35 any20973702 i need a memory manager that's many times faster than the cpus, so i can write code that has segments like [p1]...[/p1] for code sent to the appropriate cpu from a common memory, for threading
10:36 any20973702 so on a 2D matrix operation, one cpu does the even numbers, one does the odd numbers, so there's no conflicts
10:37 any20973702 or, i write : start_offset = cpu# ( assuming the cpu is hardwired to know it's number)
10:38 y20973702 resumes ponde
10:39 any20973702 cpu# is prolly the cheapest way to do it
10:42 any20973702 altho this runs the risk that , even with dynamically assigned cpu numbers, a program might call on a cpu that isn't there, so the code is never run
10:46 any20973702 i'd haveto make flags set when a thread is started, and for a threaded portion, have each cpu look at the thread flags, see if one wasn't started, and then assume a different cpu# and run it
10:47 any20973702 that would cause a speed hit only if the hardware was starved of physical cpus
10:48 any20973702 will be tricky if a thread becomes threaded, and i have code in Tiggr that exponentially explodes like that
10:50 any20973702 one reason i stopped using the VIC and C64, and turbo pascal on dos/wintel, was call stack overflows
11:00 y20973702 ponders a 2x2x1 inch block, with a .1 grid on each 2x2 face, a few pins on the other faces, and 8 10Mhz 6502 in
11:02 any20973702 it would be smaller than many 3Ghz cpus with their heatsinks, would not need a heatsink, would have 8 cores, and would run at an incredible 80Mhz with 8x [memory buss, data buss, general io buss, interrupt lines]
11:04 any20973702 if the block was 6x2x1 inches, then it would run at 240Mhz and standard obsolete cheap pc memory modules could plug into it too
11:05 any20973702 i think that would finally haul the C64 into the 1990's!
11:05 any20973702 late 1990's
11:06 any20973702 where it would die again because of lack of parallel code base
11:07 any20973702 240Mhz, 24-core 6502 with 8x 1GB memory modules on it's back
11:08 y20973702 looks at zhanx to see if there's a market for such a b
11:54 any20973702 and with pwm, adc, dac, spi, and other letters on the sides
12:03 any20973702 rue, for mecha :
12:03 any20973702 100% NEW 12V Winch Motor for RAMSEY Bi-Directional HD MBJ4407
12:03 any20973702 $86.73
12:03 any20973702 Buy It Now
12:03 any20973702 Free shipping
12:04 any20973702 it's basically a car starter motor, with ball bearings and extra wiring terminals, longer shaft, keyed
12:05 any20973702 some 12vdc 2000in-lb (160ft-lb) winches are cheaper
12:12 any20973702 i wonder if all the useful common sense and encyclopedia data would fit into 8GB, that's 1/2 the size of wikipedia even without the pretty pics
12:14 any20973702 6x6 face can hold 24 1GB modules
12:14 any20973702 put anotehr 24 on the other side
12:15 any20973702 6x6x1 , use the 1x6 sides as general io (keybd, video,spi,parport,adc,dac,etc)
12:18 any20973702 a 2x2x1 block could have a 6x2x2 memory block plugin, holding 16 modules
12:18 any20973702 it would look wierd
12:41 any20973702 <ding> it is noon, 20 minutes ago </ding>
12:41 any20973702 NO NEED TO RUSH THE ESCAPE DOORS
17:23 y15148158 has been sweating all over the s
17:25 anx has been taking care of the mon
17:25 zhanx and wow, you confused me on the hardware
17:25 any15148158 which?
17:26 zhanx its like you want a cluster
17:26 zhanx but modular with plug and play addon's
17:26 any15148158 sort of, yeas
17:27 zhanx parallax makes a multi core chip, only issue would be the memory
17:27 any15148158 also, short signal paths, versatility, and if i can build it in a 3U chassis why take up a whole desk with it?
17:27 zhanx I could see a cluster of these to crack passwords in seconds
17:27 any15148158 the pop chip is very io bound, all those cores with one io buss
17:29 anx introduced a bug into his code last night while sleep coding. I may have saved 14k of space on the chip but, I gots a debounce bug that is setting a counter off when it shoul
17:29 any15148158 downside if i build with normal 6502 as cores, they are slow
17:30 zhanx arm chips
17:30 y15148158
17:30 zhanx the stm32f4 or f3
17:30 any15148158 i know arm are a relative of the 6502, but it's still such a different chip
17:31 zhanx coding is still coding
17:31 zhanx you know that
17:31 any15148158 yeas
17:31 zhanx Moral question
17:31 any15148158 hmm?
17:32 zhanx I started with a code based that is open source, for my menu system, but I got like 3 lines of original code. how do i credit the original guy?
17:32 zhanx he wrote very bad code that was not modular and basically to be honest shit but worked
17:32 any15148158 *3 lines* ? you'd have never thought of those 3? if you would have, then i'd credit him for the inspiration
17:33 zhanx visually it looks the same but is 10x faster and 1/3 the size
17:34 zhanx well mostly the same, I can change from portrait to landscape on the fly etc now
17:34 any15148158 ok, i'd credit him with the gui design, and you wrote new code to make it happen
17:35 zhanx its a super fork of his code
17:35 any15148158 if it's only 3 lines, it's more than a fork
17:36 zhanx does it count if the 3 lines are includes for .h's?
17:36 any15148158 no, then the 3 lines don't count at all
17:37 any15148158 does wine credit microsoft for any code?
17:37 zhanx yes
17:37 any15148158 <blink> and MS didn't sue themfor theft?
17:38 Tom_itx does MS give anybody credit for code?
17:38 zhanx no
17:38 zhanx and they get sued
17:38 Tom_itx they stole alot of theirs
17:38 any15148158 yeas, actually, they got sued enough to give credit for some dll and exe
17:39 zhanx heck i even got code in windows xp :)
17:39 zhanx I wrote one of the patches back in sp2
17:39 any15148158 how did that happen!?
17:40 zhanx I worked for a place that shared resources with them
17:40 any15148158 and then you thought carrying a rifle in Iraq and getting mortared was a betetr deal?
17:40 zhanx my patch for the flaw was rolled out and tested by us, probably better that ms does. Yep it was at the time
17:41 any15148158 yipes
17:41 zhanx i just found a spot to cut 500 more bytes out of the used ram.
17:41 zhanx need all i can get
17:42 any15148158 it's fun when that happens :-)
17:43 zhanx woot! got 610 after compile
17:43 any15148158 i wonder how far you could get in college credits under VA
17:44 zhanx i got 96 credits right now and they will pay for 3 more years full time for me
17:44 any15148158 good deal
17:45 any15148158 better lock them in before October , things may get cut back
17:45 zhanx yep, i am locked in already
17:46 zhanx is it bad i am like, ok i used that same code 8 times, time to reduce it to a function call?
17:46 any15148158 if you can tolerate the overhed of the call, i'd reduce it to a call
17:46 zhanx i can
17:47 any15148158 some people reduce one line to a call, not knowing how much that hurts performance
17:47 any15148158 "but it looks better"
17:47 zhanx actually on second thought I can take these 98 lines and make it 10,
17:51 any15148158 ....The Congressional Budget Office predicts this will delay a potential default until October or November 2015.....
17:52 any15148158 and it's still not in the news, but they'll give 10 minutes every nite to a certain 4 people and house fire
18:06 any15148158 ok, back outside to cut steel
18:06 y15148158 sleeps the p
19:58 rue_house no kat
20:23 y76133723 hmm?s at
20:46 any76133723 zhanx , it makes me uneasy that the STM32F4* family is so huge
20:47 any76133723 at any mnute they could chop the family in half, ceasing production on half, and orphan dozens of cpus
20:48 any76133723 AND, there's no programmig manual for the STM32F469II
20:49 any76133723 This programming manual provides information for application and system-level software
20:49 any76133723 developers.
20:49 any76133723 nothing for hardware
21:04 zhanx I got one line of code out of 18,168 that is wrong and damn if i can find it
21:05 zhanx getting mad
21:08 any76133723 then how do you know it's just one line wrong?
21:14 any76133723 ah, they hide the menu items behind javascript, that's why i couldn't find them
21:24 any61790618 dunno what that was, but the lan suddenly got REAL busy, i yanked the ethernets
21:45 any61790618 1 GHz, 5,500 V/us Low Distortion Amplifier
22:03 Tom_itx not looking forward to soldering a 56 TSSOP or 3
22:04 Tom_itx https://www.pericom.com/assets/Datasheets/PI5C16211.pdf
22:17 y61790618 hmms at that rating of 1Ghz, since at a gain of 2 it dies at 50
22:18 any61790618 Tom, you needed two 13bit busses?
22:19 any61790618 and note the datasheet is misleading, the A-B propogation time may be "near zero" , the output enable time is 7ns - 11ns
22:40 any61790618 er, 12bits
22:40 any61790618 i thought you had some GTL buss switches
