#garfield Calendar
12:12 AM polprog: good morning
12:47 AM rue_mohr: morning
12:48 AM rue_mohr: isn't it awesome to add 2 transistors, 4 resistors, 2 diodes and have a 9 button keyboard decode itself!
12:56 AM rue_mohr: oops, I wonder if my brief encounter with video games came thru a bit on that one
12:56 AM rue_mohr: I should have blown on it :)
01:08 AM polprog: haha
01:08 AM polprog: good job on these disks
01:09 AM rue_mohr: not much I can do with fiber channel tho
01:09 AM polprog: the first image has heavy cyberpunk vibes
01:09 AM rue_mohr: heh
01:36 AM rue_bed: so, it looks like those stubby markers are a bust
01:36 AM rue_bed: they dry up too fast
01:37 AM rue_bed: the tip goes dry
08:21 AM polprog: ugh, qt programming now
08:34 AM polprog: load data from csv
08:34 AM polprog: first columnt is a 6 digit number
08:34 AM polprog: in groups of 3 digits separated by a space
08:34 AM polprog: im going to smack someone with a really heavy learning stick one day
08:34 AM polprog: naughty!
08:34 AM polprog: oh god no
08:35 AM polprog: its actually two columns separated by a space.. do they really want us to be writing Qt applications and at the same time load data with cin >> x >> y; ?
08:36 AM polprog: most of my work this semester so far was exterminating comma as a decimal separator
02:45 PM Tom_L: qtpyvcp
03:55 PM polprog: pretty much
04:05 PM zhanx: well crap
04:06 PM zhanx: interview is done
04:06 PM Tom_L: now what?
04:06 PM zhanx: I got offered a job i didn't expect
04:06 PM Tom_L: heh
04:06 PM zhanx: 2nd shift supervisor
04:06 PM Tom_L: good or bad?
04:06 PM zhanx: good?
04:07 PM Tom_L: gonna take it?
04:07 PM zhanx: they want me to train up for 30-60 days and run the plant for second shift
04:07 PM zhanx: waiting on the offer to decide
04:07 PM zhanx: i thought i was interviewing for a tech
04:08 PM Tom_L: and what did they think?
04:08 PM zhanx: they knew that
04:08 PM polprog: nice
04:08 PM Tom_L: aparently they figure you can do more
04:08 PM polprog: you need to work on your cover more ;)
04:08 PM zhanx: oh i can, i was wanting to be lazy is all
04:09 PM Tom_L: but you didn't specify that on your resume
04:09 PM zhanx: the shift is only 45 people
04:09 PM zhanx: true
04:09 PM zhanx: but i applied for the tech job
04:09 PM zhanx: 1st shift
04:10 PM Tom_L: super probably makes more and hands on does less
04:10 PM zhanx: something like that
04:10 PM Tom_L: but
04:10 PM Tom_L: 2nd shift gets blamed for everything
04:10 PM zhanx: i am responsible for the whole thing
04:13 PM zhanx: either way Tom_L at least they want me
04:38 PM aandrew: want Borland CPP Builder 3.1 from 1992? http://fabiensanglard.net/Compile_Like_Its_1992/tools/BCPP31.zip
04:38 PM aandrew: (that website has LOTS of really interesting pages in it, beware though, it's a real rabbit hole deeper than the one in Alice in Wonderland)
04:39 PM polprog: wanna hear something better?
04:39 PM polprog: i got SMB working between the lab PC and win 10 laptop
04:39 PM polprog: and win 10 automatically detected the printers connected to the lab PC
04:39 PM polprog: the only one configured on there is the 9-pin OKI ML 3320
04:39 PM polprog: which means, that i can print over WiFi to a dot matrix printer
04:42 PM zhanx: nice
04:49 PM Tom_L: can you get the whole pi4 doc in pdf? or is it online only?
05:04 PM zhanx: think its only online
05:36 PM rue_shop1: ooof
05:39 PM zhanx: what you break rue_shop1
05:52 PM polprog: hmm, booting MtXinu craps out in a weird kernel routine
05:52 PM polprog: the CPU is probably too fast
05:52 PM polprog: that routine name sounds like some calibration loop
05:53 PM polprog: ill have to kickstart the 486
05:55 PM polprog: rue_shop1: want something to match your counter? https://twitter.com/Foone/status/1259978154023645184/photo/1
05:59 PM rue_shop1: heh
06:03 PM polprog: aandrew: hmm, there are tons of sources for various *bsd from the era out there, i wonder if that could compile them
06:03 PM polprog: not that i like to hurt myself, just curious
06:12 PM polprog: rue_shop1: what are you using to draw 2D cad?
06:12 PM polprog: im messing with LibreCad, wanna know if its worth to continue this way or learn something else
06:13 PM Tom_L: i've never used it but you could look at sheetcam
06:13 PM Tom_L: freecad
06:14 PM Tom_L: not sure what sheetcam has in the way of cad
06:16 PM Tom_L: polprog, what do you want to do with it? print drawings or what?
06:16 PM polprog: mostly do drafts
06:16 PM polprog: ive used freecad a bit
06:17 PM polprog: its nice.. but quirky
06:17 PM Tom_L: all the free ones are quirky
06:17 PM polprog: tried to make a box with a cover several times, it just wouldnt let me add inter-object constraints
06:22 PM Tom_L: you might look again. they've done some work to it
06:22 PM polprog: ill do
06:23 PM Tom_L: i didn't like it but i'm spoiled with commercial cad cam packages
06:26 PM polprog: goodnight
06:26 PM polprog: i guess they will teach us cad later on at the uni
06:26 PM polprog: probably solidworks
06:27 PM Tom_L: it's a good one to learn
06:28 PM Tom_L: you can get a student copy probably free for a year
06:31 PM polprog: yeah, like with eagle
06:31 PM polprog: rue_shop1: http://ruemohr.org/~ircjunk/rockers/images/pepsisrock.jpg do i spy an agilent there :v?
06:32 PM Tom_L: oh you could get fustion360 free for a while
06:37 PM polprog: aight
06:37 PM polprog: gotta hit the bed..
06:37 PM polprog: cya
06:40 PM Tom_L: bye
09:48 PM rue_shop1: ok
09:49 PM rue_shop1: you CANT use transistors as two diodes to make an OR
09:49 PM rue_shop1: the BC diode will conduct in reverse with BE current
09:49 PM rue_shop1: now I can STOP trying to do it...
09:50 PM rue_shop1: and move on...

10:15 PM Tom_L: try again
10:15 PM Tom_L: one transistor or gate
10:16 PM Tom_L: but not as 2 diodes
10:21 PM rue_shop1: yea no
10:22 PM rue_shop1: so, the idea was that a transistor is equiv to two diodes
10:22 PM rue_shop1: but its not
10:22 PM rue_shop1: the BC diode will close
10:22 PM Tom_L: no it's not
10:26 PM rue_shop1: what project do I work on now?
10:26 PM rue_shop1: I'm severly overextended
10:26 PM rue_shop1: if I was a robot there would be like 5 instances running right now
10:27 PM Tom_L: i still think there are, some may have locked up
10:28 PM rue_shop1: so, one of the customers at work wants a fancy door alarm
10:28 PM Tom_L: i've been thinking thru what i'll need to do when the pi gets here
10:28 PM rue_shop1: got a chance to use my tom programmer today while building it
10:28 PM Tom_L: :)
10:28 PM Tom_L: still works?
10:29 PM rue_shop1: oh yea
10:32 PM Tom_L: he uses the parallel port interface on that board for spi as well
10:33 PM Tom_L: just reflash the fpga
10:33 PM rue_shop1: ...
10:33 PM Tom_L: so i gotta make a ribbon to the pi from a 26 pin 2 row header
10:39 PM Tom_L: can you read the config file on the pi with a txt editor?
10:43 PM rue_shop1: dont know
