18:42 <Nothing\> man my mind's been blown again
19:00 <Nothing\> apparently the math of ohm's law can be applied to sound just the same as electricity
19:20 <T3sl4> yeah, acoustic and mechanical impedances are a thing
19:25 <DHess_US> Rain incoming. There must be rain incoming because I just reapplied the paint stripper that the unscheduled rain washed off yesterday 15 minutes after I applied it.
19:44 <Nothing\> except with values for intensity, particle velocity, impedance and sound pressure
20:03 <Nothing\> T3sl4: yeah i didn't even think of impedance applying to sound
20:13 <Nothing\> i love it when i find connections like this
20:41 <Nothing\> learning is almost like being a detective at times
20:44 <T3sl4> http://www.ustream.tv/channel/8j3ZHU7kdge/pop-out
21:08 <Nothing\> lol DHess_US we're supposed to get rain here too
21:11 <DHess_US> impedance is also the ratio of torque to RPM making transmissions transformers.
21:16 <Nothing\> and 45 degree humidex :/
21:26 <T3sl4> it's humid as hell here
21:48 <T3sl4> been raining since 6am or so, light never got much brighter in the last 4 hours either
21:56 <Nothing\> DHess_US: took me a second to get what you were saying, you mean like gear ratios and that?
22:01 <DHess_US> And momentum and modulus are equvalent to capacitance and inductance.
22:09 <DHess_US> Nothing\, yes
22:20 <Nothing\> DHess_US: oh actually i think i know what you mean now, i realized the other day that a transformer is basically like a gear set, pulley or lever for electricity
22:42 <Nothing\> that also blew my mind
22:49 <DHess_US> A transformer changes the ratio of voltage to current and a transmission changes the ratio between torque and speed.
23:08 <Nothing\> DHess_US: i figured out the momentum thing sort of a few weeks ago when i realized the formula for kinetic energy is the exact same as the formula for the energy in a capacitor
24:10 <T3sl4> the formula for torque is the exact same as the formula for work
24:39 <T3sl4> so whether you're working or twerking is a simple matter of 90 degrees
25:00 <Nothing\> i never did learn much about torque and angular momentum and such, something about it put me off, maybe intimidation
25:24 <T3sl4> you have extra units due to the rotation and moment aspect
25:37 <T3sl4> it may be confusing due to the different reference frame, or lack thereof
25:38 <Nothing\> it's not as intuitive as linear motion is
25:41 <Nothing\> yeah exactly
26:24 <Nothing\> though i seem to get it well enough, i least can explain the difference between centripetal and centrifugal force and know how to put somebody in their place when they try to say there's no such thing as the latter
26:37 <DHess_US> https://ccrma.stanford.edu/~jos/pasp/Equivalent_Circuits.html
26:46 <Nothing\> ooh
27:36 <Nothing\> DHess_US: this is very different to what i was expecting, i was expecting those hydrological analogies people always give to novices when they start learning about electricity
27:51 <DHess_US> They apply also.
27:59 <DHess_US> It isn't like either is wrong.
28:52 <DHess_US> Also, don't forget the dashpots, https://ccrma.stanford.edu/~jos/pasp/Dashpot.html
28:54 <Nothing\> i always thought they were flawed, at least the one for resistance equating it to a constricted section of pipe, the explanation is that the fluid will slow down when it enters the thinner part, but that's not true at all, it speeds up because of the venturi effect, but the amount of energy required to push it through is higher i think
29:28 <Nothing\> unless electrons happen to speed up when encountering higher resistance
29:41 <T3sl4> well, they do, you just don't notice it because electron flow really doesn't matter
29:52 <T3sl4> higher current density = higher charge drift rate
29:59 <Nothing\> damn this stuff's gold DHess_US i'm totally bookmarking this
30:01 <DHess_US> A pipe is a transmission line.
30:11 <Nothing\> T3sl4: is that down to the repulsion of the like charges?
30:30 <T3sl4> there isn't much repulsion because the charges are embedded in an ion lattice
30:43 <Nothing\> oh so it acts like one big charge?
30:51 <T3sl4> it's just a soup of electrons moving collectively
30:54 <Nothing\> or how does that work
31:00 <T3sl4> physicists refer to it as an electron gas
31:05 <Nothing\> i like that term
31:39 <Nothing\> i always heard it described as a metallic bond, but i guess that more refers to individual atoms rather than the system as a whole
32:22 <Nothing\> so i guess the pi 4 has some pretty bad issues with overheating, on top of the non-standardised usb c ports
32:23 * Ampera hugs Nothing\ 
32:28 <Nothing\> hey Ampera!
32:31 * Nothing\ hugs Ampera 
32:34 <Ampera> 5/6 films done, Nothing\, and I am almost done with the 6th
32:37 <Nothing\> how you doing, man?
32:42 <Nothing\> films? of what?
32:46 <Ampera> editing
32:50 <Ampera> my job
32:53 <Nothing\> oh yeah your new job, nice
32:59 <Ampera> I had to edit 6 short films
33:05 <Nothing\> don't work too hard, i'm assuming you get paid hourly
33:09 <Ampera> nope
33:13 <Ampera> lump some
33:19 <Nothing\> really, wow you've got it made, man
33:24 <Nothing\> also, sum :P
33:29 <DHess_US> <Nothing\> so i guess the pi 4 has some pretty bad issues with overheating, on top of the non-standardised usb c ports
33:33 <DHess_US> I could have told you that.
33:57 <Ampera> sum, whatever
34:14 <DHess_US> It draws twice as much power for less than twice as much performance in the same physical size.
34:15 <Nothing\> DHess_US: i'm not surprised, my 3 runs hot as it is when i just tax one of the cores, nevermind all 3
34:18 <Nothing\> er 4
34:55 <Ampera> The USB C ports are standard, the issue is with hardware identification for some devices, where the Pi 4 is wrongly identified as not needing power
35:01 <Ampera> this only happens on a handful of chargers
35:10 <K> propper gigabit ethernet and usb3 is nice though
35:14 <DHess_US> Yea, it happens with the chargers which follow the standard properly.
35:29 <DHess_US> But the gigabit ethernet and USB3 controllers are crap.
35:30 <Ampera> the overheating problem also isn't as bad as people are saying, as there is A. thermal throttling B. not really ending up /that/ hot in good conditions C. a 40 dollar price tag
35:34 <Nothing\> ah yeah that seems to ring a bell
35:52 <DHess_US> Thermal throttling used to be considered a failure until they redefined it.
36:17 <Nothing\> Ampera: well the article i was reading was saying just using one of the usb ports was enough to cause throttling, but the guy was running it in a case (the standard one, i guess) with no heatsinks or fans, so what does he expect
36:25 <Nothing\> lol DHess_US
36:28 <DHess_US> It's nice that it has some resistance to self destruction but if you are operating at the point where thermal throttling is occuring, then reliability is compromised.
36:30 <K> are there any tests for giga/usb3 being crap on rpi4?
36:33 <Nothing\> so what, now it's a "feature"?
36:57 <DHess_US> K, the ethernet and USB3 controllers they used are known to have problems.
37:03 <Ampera> Again, 40 bucks, and people were trying to squeeze every bit of anything out of them.
37:10 <Nothing\> DHess_US: that's the thing, my 3 will throttle before i even come close to maxing out all 4 cores, and this is with heatsinks and no case
37:30 <Nothing\> i haven't done any proper benchmarking though, i'm almost scared to
37:37 <Nothing\> not really, but you know
37:39 <DHess_US> You know things are bad when Realtek is considered better.
37:45 <K> 40 bucks is an argument, yes
37:56 <Nothing\> actually i was surprised to learn the other day that the nintendo switch is a system on a chip
38:00 <Nothing\> a57 i think it was
38:26 <Nothing\> i was wondering how on earth they fit the entire thing into what's essentially just a screen
38:40 <DHess_US> Don't misunderstand me. It is a great value for the money. However it is not reliable or well designed.
39:04 <Nothing\> and today i was boggling over how the joycons even charge, there's no metal and no visible contacts on the part that slides into the console, so i have no clue how it makes any sort of electrical contact
39:11 <Nothing\> the only metal surfaces are painted and nonconductive
39:28 <DHess_US> This is also reflected in the closed source and undocumented nature of the hardware.
39:43 <Nothing\> the pi's closed source?
40:00 <DHess_US> Like nVidia, I'm sure if you go digging Broadcom will threaten you legally.
40:02 <DHess_US> Yes.
40:05 <DHess_US> Still.
40:09 <Nothing\> it seems like if anything, the pi would benefit the most from being open source
40:14 <DHess_US> I looked. The documentation is not availab.le.
40:26 <Ampera> I think I've heard enough to remind myself that ARM is a fucking mess, and that I should stick with PC compatibles
40:42 <Nothing\> i found circuit diagrams for the pi
40:53 <Nothing\> they were just on the documentation site
41:07 <DHess_US> Ampera, specially considering that these ARM parts are climbing up the power/performance curve so the same investment in PC hardware yields 10 times the performance.
41:26 <Nothing\> but yeah i don't recall seeing anything more in depth, then again i didn't really look much past the several hundred page documentation
41:38 <DHess_US> Nothing\, look carefully. Only some of the peripheral circuits are documented.
41:41 <Ampera> DHess_US, not to mention the huge backstock of second hand PC hardware
41:56 <Nothing\> DHess_US: ah, yeah i didn't look into them very in depth
41:58 <DHess_US> I wanted to look into details on the USB3 and Ethernet.
42:27 <DHess_US> But the only documentation I found was possibly the source for the Linux drivers.
43:05 <DHess_US> Although what they do provide does show where they screwed up the USB connector.
43:40 <Nothing\> the article i was reading earlier today was saying that the 4 will throttle when you just use one of the usb ports
43:52 <Nothing\> from taxing the system, i guess
44:29 <Nothing\> the article wasn't that great anyways, it sounded like this guy just made some speculations based on his own anecdotal experiences
44:38 <Nothing\> which is not a hallmark of a good tech journalist
44:39 <DHess_US> It throttles very quickly.
45:40 <Nothing\> hrm my brother's supposed to be getting out of the hospital tomorrow, makes no sense cuz they still don't know what's wrong with him
46:31 <Nothing\> he's been in there for the last week with rhabdomyolysis, where your kidneys become overwhelmed by dead muscle cells, but it's not something that just happens, there's always an underlying cause, usually metabolic or some injury to a muscle like a crush injury but he has none of those
47:02 <Nothing\> his arms are so weak he can't even lift himself out of bed, yet they think he's well enough to go home
48:24 <T3sl4> that sucks
49:19 <Nothing\> oh i know, he must be going nuts in there
49:36 <Nothing\> i can scarcely wait in the ED for 2 or 3 hours to see a doctor, nevermind being in there for a week
50:11 <Nothing\> i figure if anything ever happened to me i'd probably die before i got admitted to the hospital lol
51:41 <Nothing\> man this desmos.com online graphing calculator is awesome, it's way easier to use than geogebra
52:34 <Nothing\> i like being able to actually do these math things i'm learning about like calculus, but i tried doing it by hand the other day just graphing a simple square curve and it was so lumpy, i couldn't draw a tangent for the life of me, nevermind secants
52:58 <DHess_US> Went I went to the ER a couple years ago for gall stones, which eventually ended up with me in the hospital to have my gall bladder removed, I had to spend a couple hours writhing on the floor of the ER in pain.
53:16 <Nothing\> it's amazing when you think about how much hand calculations the mathematicians did before computers
54:53 <Nothing\> DHess_US: oh jeez i had a friend who went in to have gall stones removed in a hospital in jersey, the doctor couldn't find his gall bladder so he went poking around in his liver and wound up destroying a good chunk of it, which led to liver failure and he wound up being hospitalized for weeks, not to mention having a good chunk of time shaved off his life
55:13 <Nothing\> needless to say he got a hefty settlement out of it, but it's just not worth it imo
55:26 <T3sl4> the fuck
55:31 <Nothing\> i know, right?
55:36 <Nothing\> i woulda slapped that doctor
56:02 <Nothing\> i'm not sure exactly what he did to his liver but i always assumed his hepatic artery was severed
56:23 <Nothing\> that seems to be a pretty common complication of liver surgery
56:58 <DHess_US> That's a little weird. The liver however can regrow.
56:59 <Nothing\> i don't think he qualified for a transplant either cuz he was a drug user, or at least a recovering drug user
57:24 <DHess_US> The gall bladder can have quite a bit of natural variation.
57:33 <Nothing\> DHess_US: oh yeah i was gonna mention how amazing it is that the liver can regenerate from a relatively small piece
57:40 <Nothing\> DHess_US: i didn't know that
57:55 <DHess_US> In my case, they could see on the CAT scan and sonogram that my gall bladder was going to have to be removed. There was no question about dealign with gall stones.
58:44 <Nothing\> DHess_US: i didn't even think of that, it turned out he didn't even have a gall bladder, so i dunno what idiot they had interpreting the imaging
59:26 <Nothing\> it didn't occur to me they should have done imaging first to figure out where it is and whether he actually needs surgery or not
59:45 <DHess_US> He probably needed the surgery anyway.
59:58 <Nothing\> i'm not sure what the problem wound up being
00:02 <DHess_US> So the imaging wouldn't matter. In my case, they still needed a positive diagnosis.
00:31 <Nothing\> yeah you'd think that would be the first priority before surgery, determine whether they actually have the condition you're doing surgery to correct
00:41 <DHess_US> Doctors dont' like it when someone shows up in the ER with 15k white blood cell count, ketosis (starving), and high glucose (well fed).
01:28 <Nothing\> oh man i should look up videos of surgeries, i used to watch this show on TLC back in the 90's called, appropriately enough, The Operation, where they'd have an hour long program showing a surgery while explaining what's being done, it was one of my favorite shows as a kid
01:29 <DHess_US> Once they saw that, they told me I wasn't going anywhere.
02:07 <Nothing\> they even did an episode for a vasectomy, and i tell you even though that was like 25 years ago, those images are permanently etched into my retinas. there's absolutely no way i'm ever getting a vasectomy after seeing that
02:24 <T3sl4> loved operation
02:35 <Nothing\> you watched it too? that's awesome
02:47 <Nothing\> back when TLC was actually educational and not geared towards women with PMS
02:51 <T3sl4> always amused me that some people couldn't "stomach" it, let alone while eating dinner, say
03:20 <Nothing\> haha yeah my mom always commented how unusual it was that i was able to eat while i watched it
03:40 <Nothing\> it's weird though, i can't stomach stuff like that anymore for some reason, it's like i've become sensitized to it somehow
03:56 <Nothing\> i tried to watch a surgery for carpal tunnel syndrome a while ago and i couldn't even sit through it
05:19 <Nothing\> heh when i was a teen, my best friend worked as an intern as a funeral director, so i'd always go over to the funeral home at night and keep him company while he prepped a body for a service
06:16 <Nothing\> for some reason the thing that surprised me the most was the fact that they're naked while this is being done, i guess with all of the other stuff going on you don't really give much thought to what they'd be wearing
06:38 <T3sl4> that's the last step
07:08 <Nothing\> yeah it really wasn't as gruesome as people assume it is
07:16 <DHess_US> Morticians work naked? I've heard enough, thanks.
07:18 <T3sl4> especially if you have to clean up an old body or deal with an autopsy
07:30 <Nothing\> the worst was making the incision to insert the canula into the corrotid artery for the embalming fluid
07:58 <Nothing\> T3sl4: it's amazing how well they can reconstruct a person's face, of all the work they do, the most effort goes into the make up
08:13 <T3sl4> yep
08:31 <Nothing\> even if a person took a shotgun to the face and blew half of their head off, they can still reconstruct it out of, i think they use wax
08:42 <Nothing\> i never saw anything like that though
09:11 <Nothing\> usually just from a couple of photographs for reference
09:16 <desu> will they melt in the sun
09:27 <desu> spooky
09:30 <Nothing\> lol that conjurs up some amusing images
10:02 <Nothing\> actually it reminds me of that bit from the simpsons where there's a heatwave and skinner's at a wax museum and comments that he's up to his knees in the cast of MASH
10:08 <Nothing\> cuz they were all melting
10:10 <desu> also facial transplants are a thing now i think
10:33 <Nothing\> desu: i believe they are, i remember seeing something about one being done like 10 or 15 years ago, it was quite a while ago
10:39 <Nothing\> same with a hand transplant
10:58 <Nothing\> it's amazing to think they can connect all of the tiny, almost microscopic nerves like that
11:11 <Nothing\> i wonder how they'd attach the muscles
11:30 <Ampera> AND RENDER
11:31 <desu> wounder if they have to take those immuno supressive drugs for hand transplants and such
11:37 <desu> or if that only applies to vital organs
11:39 * Ampera collapses on the floor
12:02 <K> and then it runs out of disk space on 89%
12:19 <Ampera> no I have tons of disk space
12:19 <Nothing\> desu: yeah pretty much anything organic that doesn't come from your body is considered an invader to your immune system
12:33 <Nothing\> desu: i've even heard of immune responses to non-organic implants
13:09 <Ampera> So this is video editing for an I believe for profit (or at least paid) film summer camp
13:13 <Nothing\> though i don't think it's quite the same, i think it's just an inflammatory response for nonorganic implants
13:21 <desu> well skin transplants
13:23 <Ampera> and the last film I just did had a load of chroma key, to which I expected to have been given images.
13:26 <Nothing\> Ampera: a bit late for that, isn't it?
13:27 <desu> im pretty sure they don't need to take that for those
13:29 <desu> at least forever?
13:36 <Ampera> I was given two, and one had a resolution below 320x200
13:46 <Nothing\> desu: for organic transplants i think they do have to take them for life
14:03 <desu> sad
14:13 <Ampera> when I asked for more, I was told to find some myself, and when I asked about copyright, it basically amounted to, well we're not selling the videos, so it's fine
14:29 <Ampera> so whatever
14:32 <Nothing\> desu: your immune system identifies your body's cells based on certain proteins that are on the surface, so if it encounters cells with different proteins it assumes it's an invader and launches an immune response
14:55 <Nothing\> Ampera: but copyright doesn't only apply to sales
15:01 <Ampera> exactly
15:11 <Ampera> and it doesn't matter if they are selling the video, they are selling the camp
15:17 <Nothing\> i mean, anyone who's seen one of those FBI warnings at the beginning of movies knows that
15:30 <desu> you wouldn't download a car
15:31 <Nothing\> actually they don't even put those warnings in movies anymore lol
15:39 <Nothing\> desu: damn right i would download a car
15:45 <Nothing\> who are they to make that assumption about me
15:48 <Ampera> I mean if they are registered non-profit, and it is genuinely an educational thing for little children, I think no court of law would go down on anyone for that
15:57 <desu> those always scared me as a child
16:08 <Ampera> I told them my main thing is I don't want to be the guy who gets them sued.
16:11 <Nothing\> Ampera: yeah that seems a bit far fetched
16:15 <desu> i remember they had those on every single mopvie from the VHS rental place
16:35 <Ampera> in other news, nvenc h.264 is faster than CPU mpeg4
16:36 <Ampera> somehow
17:22 <Nothing\> desu: lol i didn't pay any mind to them, but i remember the first time i smoked pot, this guy traded me a piece for a slice of pizza, and i walked home holding it in my hand inside my pocket, the whole time i was terrified i was gonna be stopped by cops or that somehow people knew
17:28 <Ampera> https://www.youtube.com/watch?v=0vOzehp5BKg
18:10 <Nothing\> but we made copies of all sorts of stuff on VHS back in the day
18:44 <Nothing\> heh the holy grail was when you'd get a channel that airs a movie and whomever records it took the time to stop recording during the commercials
19:04 <Nothing\> though i tried to do that and more than once i'd forget to hit record when the movie came back on
19:17 <desu> wheren't like boxes that recorded shows a thing for a while
19:19 <desu> that ppl had
19:22 <Nothing\> ah, problems nobody will ever have ever again in the entirety of history
19:28 <Nothing\> isn't that interesting to think?
20:01 <Nothing\> desu: yeah they had things like TIVO where it was i guess like a computer with a harddrive that recorded shows for you
20:50 <Nothing\> or for VHS technology, pretty much from the start VCRs were marketed towards people who wanted to record shows they didn't have time to watch, so timers for recording were a pretty standard feature from the get go
21:44 <Nothing\> damn, there's so much condensation on this cup of juice that it dripped off of the cup into my keyboard
21:53 <Nothing\> left a nice sized puddle on my table too
22:21 <Nothing\> omg i just invented a device that can suck the water out of air! somebody give me $2 million to kickstart this
22:39 <desu> would it be safe to drink the water from a dehumidifier
22:50 <desu> oh
22:51 <desu> not safe
22:51 <steve30> zomgwow
22:59 * steve30 passes Nothing\ a load of $$$
25:18 <Nothing\> desu: lol yeah it's a really bad idea to drink standing water
25:43 <Nothing\> standing water in general is actually considered a health hazard, some cities will fine you for having it on your property
26:30 * T3sl4 passes steve30 a load of hugs
26:45 <T3sl4> Nothing\, yeah, fuck mosquitoes
27:02 <Nothing\> you know, it's really fun to just stare at a graph of a function and try to figure out what its derivative would look like
27:10 <Nothing\> T3sl4: man i HATE mosquitoes
27:34 <T3sl4> even more fun to figure out what its approximation would look like
27:49 <T3sl4> say in terms of polynomials (taylor series) or trig (fourier series) or ...
28:14 <Nothing\> hrm i've never gone that far, it only just clicked what a derivative is the other day
28:30 <Nothing\> such satisfaction, too. i've been wanting to learn calculus almost my whole adult life
29:17 <Nothing\> it's been a sort of holy grail for me. i always loved physics stuff and felt that i could appreciate it way more if i understood the math, and i was right. i didn't care about classical mechanics until i learned the math
29:59 <T3sl4> it's the language with which physics is expressed; it's hard to appreciate on more than a superficial level otherwise :)
39:20 <steve30> i could do with a coffee
39:44 <T3sl4> mmm, i had a tea earlier
40:38 <Nothing\> T3sl4: one interesting question i've always boggled over is whether math was discovered or invented
41:20 <Nothing\> there was an interesting article i read in scientific american like 15 years ago that got me thinking about it
41:40 <T3sl4> seems more of a language thing than a philosophical thing
42:16 <Nothing\> definitely
43:02 <T3sl4> discovery and invention are both about exploring some space
43:59 <T3sl4> you can presumably enumerate all possible algebras, say, and then "discover" any one of them by writing out the theorems that follow
44:41 <T3sl4> you can just as well "invent" one where you establish what postulates are needed for some situation, then do the same thing
50:11 <Nothing\> indeed, the two seem to feed into one another, discovery leading to invention leading to discovery by way of said invention and so on
51:26 <Nothing\> you know, i wonder what computer technology and modern life in general would be like if semiconductors were never discovered, if we still had to rely on vacuum tubes
51:55 <Nothing\> i wonder if their practical applications would have been realized to the same extent that they are today
54:50 <T3sl4> each was necessary before the next
03:46 <DHess_US> Vacuum tubes can be built on a MEMs process so there are alternative swhich would have allowed integrated vacuum tubes.
04:37 <DHess_US> Thick and thin film processes can make vacuum tubes also. Vacuum flourescent displays are an example of this.
04:54 <T3sl4> how long have VFDs been around for?
05:00 <DHess_US> Decades
05:01 <T3sl4> nixies predate them a bit i think?
05:09 <DHess_US> And there are printed processes which can produce core memory.
05:12 <DHess_US> Sure
05:27 <DHess_US> Oh, and of course all of the selectron type memories would have continued.
06:37 <DHess_US> So there was a lot of possible technologies we did not persue for vacuum based electronics.
07:28 <DHess_US> And the printed ones potentially could follow Moore's law for scaling.
11:04 <T3sl4> by the time you've got the manufacturing to a small enough scale for those, you've got the chemistry to a high enough level of purity to enable transistors

11:49 * T3sl4 glomps ThunderSqueak
12:13 <ThunderSqueak> hi there :D
12:18 <ThunderSqueak> how are you? :D
12:25 * T3sl4 waves excitedly
12:48 <ThunderSqueak> your acting as bad as my new GF <.<;;
12:52 * ThunderSqueak teases.
13:11 * T3sl4 pinches ThunderSqueak
13:20 <ThunderSqueak> yep, confirmed
13:30 <T3sl4> don't be a tease :P
13:33 <ThunderSqueak> :P
13:38 <T3sl4> ...unless you got pics
13:41 <T3sl4> (j/k :P )
13:44 <ThunderSqueak> cant help it, it is in my nature <.<;;
15:30 <ThunderSqueak> lost a LOT of weight
15:41 <T3sl4> calorie counting paying off?
15:44 <ThunderSqueak> yeah
15:49 <T3sl4> w00t!
15:50 <ThunderSqueak> down yet another belt loop
16:13 <ThunderSqueak> to the point I had to punch a hole... going to look for a new belt later today
16:20 <T3sl4> cool
17:31 <ThunderSqueak> was a bit surprising this morning actually, last week, I was on the last one, this morning, it was like so loose there was no point wearing it, but pants are the same
17:44 <ThunderSqueak> shirt is ultra baggy too
18:11 <ThunderSqueak> another month and I will start being back into older clothes
20:34 <ThunderSqueak> basically what I was wearing before putting all this on suddenly
28:02 <Ampera> \o/ ThunderSqueak!
28:04 <Ampera> how do?
29:40 <ThunderSqueak> mildly hungry ... you?
32:08 <ThunderSqueak> also, sitting in class
32:44 <ThunderSqueak> the university just had its budget cut by 130 million
32:58 <Ampera> oh nice
33:01 <ThunderSqueak> they said next semester will go as planned, but not sure of the future
33:02 <Ampera> I'm doing random things
33:24 <ThunderSqueak> they will be dropping programs most likely
33:43 <ThunderSqueak> and moving a lot of classes to distance education methods
34:07 <DHess_US> "Changing one physical law is like trying to eat one peanut."
34:52 <ThunderSqueak> *corrects that* "Changing one physical law is like trying to eat one circus peanut."
38:08 * ThunderSqueak wanders around handing out coffee and Donuts.
41:07 <T3sl4> ew circus peanuts
41:21 <T3sl4> i will however, gladly take any donuts you don't* want :)
41:22 <ThunderSqueak> rofl
41:30 <T3sl4> *or want to but can't
42:10 <Ampera> dear lord, Berkley city ordinance now to call "manhole" "maintenance hole" among other terms like manmade -> humanmade in an attempt to stamp out gender specific pronouns from existing
42:26 * T3sl4 shrugs
42:45 <T3sl4> instead of "man hole" why not "road anus"
42:47 <Ampera> I can't think of a more tediously annoying ordinance anyone could come up with.
43:07 <Ampera> Ian Miles Cheong wanted personhole
43:18 <T3sl4> Ampera, so you're saying the local politicians are doing their jobs
43:44 <Ampera> T3sl4, no politicians in the world's largest chinatown are doing their jobs
45:15 <desu> how is changing names doing their job
45:27 <desu> arn't politicans supposed to fix important things
45:41 <Ampera> desu, that's not how politics works.
45:44 <DHess_US> Yes, but only things which are important to politicians.
45:59 <Ampera> politicians' jobs are to make as much of a show as possible so people pay attention to them long enough in order for them to get re-elected.
46:11 <T3sl4> ^
50:02 <desu> yeah
50:04 <desu> i guess
53:39 <DHess_US> https://babylonbee.com/news/nasa-announces-all-female-remake-of-staged-moon-landings
54:48 <Nothing\> speaking of stupid legislation, you guys ever hear of this one?
54:50 <Nothing\> https://rationalwiki.org/wiki/Indiana_Pi_Bill
55:16 <DHess_US> Louisiana did it better.
55:27 <Nothing\> i wasn't aware they did the same thing
55:32 <Nothing\> the scary thing is, this bill almost passed
55:34 <desu> why can't they just make another moonlanding
55:44 <desu> and put women on there this time instead
55:52 <desu> doing a fake one just seems like a waste of money
56:40 <Nothing\> eh people will stop caring about the moon landings in a month or so
56:49 <Nothing\> it's just all hyped up now cuz of the anniversary
56:59 <desu> yeah it's all about mars now
57:05 <desu> moon is lame
57:14 <Nothing\> if we want to go to mars, the solution is simple
57:16 <Nothing\> go to war
57:44 <Nothing\> that seems to drive technological development enough to do such things, or rather drive the motivation of those in charge of allocating resources
57:44 <desu> lol
57:51 <desu> a new space race would be cool
58:13 <DHess_US> Oh, it was the Indiana one. Nevermind. The story gets even better if you dig into it.
58:15 <Nothing\> even if it was just good natured fun competition
58:35 <DHess_US> https://books.google.com/books?id=QhbrBwAAQBAJ&pg=PA236&lpg=PA236&dq=bill+pi+committee+on+swamps&source=bl&ots=MJQHujJwTz&sig=ACfU3U1MHHyQQQxpxgRE6DdS-GznUxWTcQ&hl=en&sa=X&ved=2ahUKEwiGoq-mh7_jAhX3B50JHbDWBUgQ6AEwA3oECAgQAQ#v=onepage&q=bill%20pi%20committee%20on%20swamps&f=false
59:30 <Nothing\> what's up with sites that have such long URLs anyways, are they trying to keep enough urls available to last until the heat death of the universe
00:20 <Nothing\> humhaw
00:48 <Ampera> Nothing\, you've reminded me that I kinda want to die, thanks for that
00:52 <Nothing\> lol my brother wants my mom to bring him immodium cuz the hospital food's giving him the shits
01:04 <Nothing\> Ampera: everybody gets one ;)
01:32 <Nothing\> really though, you don't want to die
01:58 <Nothing\> most likely you want a new, different life, but i don't like to believe that you would genuinely want to die
03:15 <Nothing\> of course, i don't mean to trivialize your problems or try to tell you what you're feeling
04:46 <Nothing\> what would the macro circuit equivalent of a multiple emitter BJT be? something like an OR gate?
04:56 <Nothing\> or i guess a reverse or gate
05:29 <Ampera> Nothing\, that's exactly right, though I am more focused on getting out of the one I have now.
05:38 <Ampera> A different one would be nice, but that's secondary.
05:51 <Nothing\> that's awesome, i'm glad to hear you're being proactive
06:06 <Ampera> I just told you I hate my life and that I wished I was someone else
06:08 <Ampera> how is that proactive
06:43 <Nothing\> i've known so many people in generally the same situation as you, depressed, unhappy with life, all that fun stuff, but i've only ever known one person who actually pulled themselves out of it, it's nice to see you're on your way to doing the same
07:13 <Nothing\> Ampera: because you're working, you're working on your mental health issues, you're fighting despite the struggle
07:22 <Ampera> It's not so much pulling myself, it's riding the currents of my life and waiting to be dropped onto whatever beach of normal stability I can
07:39 <Nothing\> ah yeah i know what you mean
07:52 <Nothing\> well getting a job is definitely proactive
09:56 <Ampera> unfortunately it's not at a gun factory
10:00 <Nothing\> it's just nice to see somebody dealing with difficulties in life in a way other than self destructive behavior, drug use and self mutilation while neglecting everything that was important
10:56 <Ampera> I had a strange dream last night.
11:04 <Nothing\> ]me too, actually
11:16 <Ampera> I dreamed that I was running around town really wanting an e-cig, but not being able to find a place that had no-nicotine liquid
11:23 <Nothing\> which is odd cuz i don't usually dream, but i'm smoking a lot less pot and didn't have any last night so i guess that's what did it
11:47 <Ampera> you need more cheese in your life
11:53 <Nothing\> hahaha man, i've had soooo many dreams exactly like that with a bunch of addictions i've had
11:57 <desu> what's the point of vaping without nicotine?
12:02 <Nothing\> dreams where i've wanted a cigarette but can't find one anywhere
12:09 <Ampera> desu, innocent habit without chemical addiction
12:18 <Ampera> but I've never smoked in my life
12:19 <Nothing\> or dreams where i'd try to smoke pot, but stuff keeps coming up to get in the way of it
12:27 <Ampera> even though having dreams about smoking before
12:29 <desu> like chewing gum then i guess
12:37 <Nothing\> Ampera: keep it that way, it's a stupid habit with no benefits what so ever
12:41 <Ampera> desu, yeah, they have flavoured ones and stuff
12:53 <Ampera> I'd be interested in trying no-nicotine vaping at some point
12:57 <desu> i really hate people who vape in public
13:02 <Nothing\> and when they say nicotine is more addictive than heroin, they're not kidding
13:06 <desu> because it smells more than ciggs
13:26 <Nothing\> i mean i can't speak for heroin, but compared to all of my other addictions, nicotine has hands down been the hardest one to fight
13:45 <Nothing\> desu: really? i always found it smells significantly less than cigarettes
13:51 <Ampera> the issue for me is that, in my present state of mind, it seems like it would be trivial to simply stop smoking if I wanted to
13:55 <Ampera> but I know that's totally not the case
14:08 <desu> i guess only the huge ones do that though
14:08 <desu> not the tiny ones
14:08 <desu> that look like cigarettes
14:22 <Nothing\> in fact my mom doessn't care that i vape in the house or in her car, but she never let me smoke in similar situations
14:24 <desu> maybe im just more used to the cigarette smell or something
14:27 <desu> i don't smoke though
14:38 <Nothing\> could be the flavor they use
14:47 <Nothing\> maybe it's stronger than what i'm used to orsemthing
15:06 <Ampera> holy shit
15:10 <Ampera> trump just apologized for saying something
15:15 <Nothing\> no shit?
15:20 <Nothing\> what was that?
15:20 <Ampera> https://twitter.com/RealSaavedra/status/1151903997038485505
15:24 <desu> i hate trump now
15:27 <Nothing\> is it about theresa may?
15:41 <Nothing\> i don't hate trump, but i think he's a terrible person to be the potus
15:53 <Ampera> I don't hate him either, I don't like him all the same.
16:00 <Ampera> I don't want him to be president, but I'm not going to join antifa because he is
16:35 <Nothing\> you think how kids idolize the president and want to be like him, or they used to anyways, and just think how all those kids will turn idolizing him, meanwhile he's saying stuff like grab em by the pussy
16:47 <Nothing\> but then it's not like he's the first potus to be crude, LBJ was way worse
16:49 <Ampera> I don't think that's gonna happen.
16:57 <desu> wasn't kennedy like that too
17:00 <Nothing\> LBJ used to randomly whip out his penis to show people
17:02 <Ampera> and that was a oneoff too
17:07 <Ampera> uhwha
17:10 <Nothing\> desu: not publicly i don't think
17:21 <Nothing\> actually LBJ even pissed on one of his aides once lol
17:22 <desu> and clinton
17:28 <Nothing\> clinton definitely lol
17:30 <Nothing\> that cigar
17:53 <Nothing\> i wonder if the cigar thing really happened or if that's just an urban myth like richard gere sticking a gerbil up his ass
17:57 <DHess_US> The most recent present that might not have been a scoundrel was Eisenhower.
17:59 <Nothing\> which how the hell did that one start? lol
18:03 <DHess_US> I especially hate Ford.
18:20 <T3sl4> DHess_US: we need another theodore roosevelt, but we surely do not deserve one.
18:33 <Nothing\> DHess_US: are we talking somebody who's really lewd or somebody who's just crooked?
18:39 <DHess_US> Yea, he was probably better than Eisenhower.
18:48 <DHess_US> Nothing\, just crooked.
18:53 <Nothing\> ah
19:03 <Nothing\> everybody's crooked in some way
19:10 <Nothing\> the only thing that's different is how public it is
19:16 <Nothing\> and to what extent
19:21 <DHess_US> Theodore Roosevelt? Eisenhower?
19:28 <DHess_US> Ford sure was.
19:38 <Nothing\> oh yeah gerald ford seemed on the money
19:39 <DHess_US> And Johnson. And Nixon. And Reagan.
19:59 <Nothing\> reagan smash
20:09 <DHess_US> But Ford I can point to an obscure thing he did which tarnishes him, all Presidents, and all of Congress.
20:17 <Nothing\> lol i still find it amusing that nixon's middle name was milhouse
20:30 <Nothing\> oh wait
20:35 <Nothing\> reagan was involved in the iran contra affair
20:46 <DHess_US> Minor compared to what Ford did.
20:50 <T3sl4> mmm, stir fry
20:57 * T3sl4 passes around a virtual wok
20:59 <Nothing\> what did ford did?
21:29 <DHess_US> Well, he pardoned Nixon but that wasn't the problem. He pardoned Nixon *without* pardoning the people who worked for him.
21:40 <Nothing\> ah
21:41 <DHess_US> they should all of been pardoned or none of them.
21:57 <T3sl4> that's how scapegoating works
22:09 <DHess_US> I don't care what the cost would have been because the actual cost was much greater.
22:22 <Nothing\> i didn't know until recently that scapegoats used to be literal goats
22:22 * Ampera throws a remote control at Nothing\ 
22:38 <DHess_US> So the only thing Ford did which was great was to reveal the hypocracy of the President and Congress. Fuck them all.
22:53 <Nothing\> it was basically a goat that villagers would use as a sacrifice to take all of the sins of the villagers or something like that
22:55 <DHess_US> And fuck all of them sense.
23:07 <DHess_US> Err, since.
23:17 <T3sl4> yeah, they don't have sense
23:19 <DHess_US> Because none of them since have tried to correct that.
24:34 <Nothing\> ugh why does simple,wikipedia.org come up when i google ttl
24:46 <Nothing\> i wonder how popular that even is
25:15 <DHess_US> TTL? CMOS replaced it except in legacy applications.
25:39 <Nothing\> oh i know, i'm just looking to play with it with discrete parts so i was gonna read up on it
26:15 <DHess_US> There is nothing wrong with it as far as performance.
26:26 <DHess_US> And it has some advantages.
26:30 <T3sl4> wiki's 7400 series list is still one of the most comprehensive, certainly the highest ranked
26:32 <Nothing\> it actually outperforms cmos in some areas, though i forget which
26:41 <Nothing\> T3sl4: oh man i LOVE that list
26:49 <T3sl4> in I_OL, i suppose
26:49 <Nothing\> they have lists for 4000 and LM series as well, btw

56:47 <Halcyon> Hey Steve :)
58:20 * steve30 hugs Halcyon 
58:41 <steve30> I should try and do some electronicsing today
59:06 <Halcyon> :)
05:15 <steve30> Hows Jerry?
05:32 <Halcyon> He is good, he is sitting my shoulder chirping
12:27 * steve30 ponders more coffee
14:51 <Halcyon> I'm considering a nap
25:09 <steve30> that sounds like a good idea too
26:30 * steve30 curls up on Halcyon's lap
27:16 <Halcyon> nAWW
27:19 <Halcyon> Cute
00:29 <steve30> yay coffee
10:58 <Ampera> Halcyon, I am now
45:42 <steve30> wow, i don't have any 120R resistors
04:29 <steve30> well, I'm pleased to say that these LTC1966 true-rms converts seem to agree with my true RMS multimeter :)
13:03 <Halcyon> *rubs eyes
13:08 <Halcyon> I just had a nap for an hour or so
13:11 <Halcyon> Feel better
13:29 * Ampera hugs the Halcyon 
13:38 <Halcyon> Nawww :) Hey Ampera
13:47 <Halcyon> My favourite American
13:54 <Ampera> my editor just reported back with two finished films (3 short films in each)
14:12 <Ampera> awww, what about jspiros?
14:17 <Halcyon> Oh yeh? Was the feedback good?
14:24 <Ampera> ¯\_(ツ)_/¯
14:26 <Halcyon> No, he's a douche
14:35 <Ampera> so am I
14:40 <Halcyon> Nah
14:57 <Ampera> I'm currently skimming through some footage trying to harvest a few clips for a small blooper reel.
16:19 <Halcyon> I'm considering a small coffee to wake me up that little bit more, but I'm also mindful it's almost 1830
16:25 <Halcyon> I want to sleep tonight
16:58 <steve30> coffee \o/
27:20 <Halcyon> I decided to make a short black
28:02 <Halcyon> Steve: Discussing coffee with Ampera on Discord
28:09 <Halcyon> Does it make you poop too ? (in the morning)
28:17 <Ampera> I already poop in the morning
28:22 <Ampera> coffee doesn't make me do that, I don't drink it
28:27 <Halcyon> As in *really* makes you poop
28:34 <Ampera> I really poop in the morning too
28:42 * Ampera shits all over Halcyon's ideas
28:48 * Halcyon shits all over Ampera
29:34 <Ampera> ew, it smells like retard
29:58 <steve30> Halcyon, it encourages it
30:19 <Halcyon> That's a good way of putting it :)
30:47 <Halcyon> I was trying to explain the sensation, since Ampera doesn't drink coffee
31:00 <Ampera> that doesn't mean I don't drink caffeine
31:05 <Ampera> I'm just saying it doesn't do that
31:24 <Ampera> I've also had coffee before, all it does is make me feel sick and weak
31:32 <Halcyon> It's different though, I could have a caffeinated beverage and it doesn't have the same affect.
38:59 <steve30> there are probably other things in coffee which make you need to go.
50:17 <Halcyon> Quite possibly
50:31 <Halcyon> I don't think it's just the stimulating affect of caffeine
02:41 <steve30> I need to try and remember how to calculate an op amp non-inverting amplifier
22:32 <steve30> hmm, apparently these CR2023 cells may lead to serious injury or death if swallowed, but only in the US and Australia.
22:39 <steve30> Looks like I'm safe to have them for lunch then :)
26:40 <Halcyon> \o/
26:47 <Halcyon> Just don't crunch down on them
26:50 <Halcyon> They hurt your teeth
42:34 <Halcyon> BRB

58:45 <steve30> yay, op amp works :)
59:02 <Halcyon> YAY!
59:21 <steve30> I'll treat myself to some dinner I think :D
09:16 <K> hello
09:17 <Halcyon> What's for dinner Steve?
09:21 <Halcyon> Evening K
09:23 <Halcyon> How you doing?
09:43 <K> fine-ish
09:51 <Halcyon> Only "ish" ?
10:12 <K> yea
10:14 <K> it is 5day
10:16 <Halcyon> What's the matter?
10:23 <Halcyon> It's wha?
10:27 <K> friday
10:31 <Halcyon> Oh
10:37 <Halcyon> It's Friday here too \o/
10:52 <Halcyon> But Friday's are awesome because I don't work
11:17 <K> in latvian it sorta makes sense if you write 1day, 2day, 3day etc.
11:35 <Halcyon> Oh I see
11:41 <Halcyon> I've never seen it done that way
11:56 <Halcyon> I guess mainly because some strange people believe that Sunday is the start of a week
12:05 <Halcyon> Where as here (in AU) it's Monday
13:33 <K> nah, week starts on monday here, as is propper
13:42 <Halcyon> I agree
15:17 <Halcyon> What's it like in Latvia?
15:28 <Halcyon> For example, what's the weather doing today?
15:30 <Ampera> Halcyon, I think I'll just install it in a VM
15:36 <Ampera> as if I want to explain it, it would be way easier there
15:48 <Halcyon> Right but will it achieve what YOU want to do?
16:18 <Ampera> yes, to show you how to install arch linux
16:25 <Ampera> which is more interesting than messing around with a lab PC
16:42 <Halcyon> Sure, well feel free to start now, Mark isn't home from work yet
16:48 <Halcyon> So I don't need to go just now
38:07 <steve30> Halcyon, chicken + roast potatoes + carrots + brocoli + yorkshires
11:46 <T3sl4> slugs are hermaphroditic, you ponce
11:46 <Ampera> T3sl4, I'm not you muppet
11:46 <T3sl4> it's a strong costume
11:46 <T3sl4> strong enough that you also die to salt
11:47 <Ampera> T3sl4, only because you've worn it for so long
11:47 <Halcyon> Anyone up for a game of something? Golf? CAH ?
11:47 <Ampera> can't working
11:47 <Halcyon> Boo
11:47 <T3sl4> Ampera cannot into fun

11:47 <Halcyon> O... K.... ?
34:20 <steve30> i think i might go for a lie down
19:00 <K> weather is nice
19:16 <K> +20C, which is a bit cold for July

30:03 <rust_collector> damn kids....
30:42 <rust_collector> don't feel like getting out of bed today, because it is raining... (has not been outside since monday)
33:02 <rust_collector> installing arch...
33:04 <rust_collector> haha
21:48 Quit: Guest|31869 ([email protected]) Quit: http://www.kiwiirc.com/ - A hand crafted IRC client
29:08 * Ampera smacks rust_collector
29:16 <Ampera> don't talk shit about arch if you wish to keep your kneecaps
29:31 <desu> install gentoo
30:06 <Ampera> desu, out of all the things you have said in the channel, of all the homophobic and horrific things you've written, that is, singularly, the worst thing you have said yet.
31:49 <rust_collector> who said anything bad about arch?
32:15 <rust_collector> I ran out of time, that will come later
32:48 <desu> shut up faggot
32:55 <desu> gentoo is good
33:44 <rust_collector> crux is ok
34:26 <desu> oh yes
34:32 <desu> thtat one is good too
34:52 <desu> and slackware
35:16 <rust_collector> yeah, but that is a bit too different
35:26 <rust_collector> Or, it includes "everything"
37:24 <desu> yeah i remember being pretty confused about that when i tried slackware lol
38:47 <rust_collector> so, talking about that... how is that austrumi thing?
38:48 <Ampera> desu: I'll ban your ass
39:07 <desu> sorry
39:18 <Ampera> it's okay, I can't help being a faggot
39:27 <Ampera> well I can, but I choose not to
39:33 <Ampera> because I wish to insult god
40:14 <desu> whats austrumi
40:33 <desu> https://distrowatch.com/table.php?distribution=austrumi
40:35 <rust_collector> latvian loonix distro, based on slackware
40:41 <desu> oh weird foreign distro
41:26 <desu> https://distrowatch.com/table.php?distribution=opnsense
41:27 <desu> oh cool
42:56 <rust_collector> I wonder if the old p4box still has arch installed on it
48:03 <desu> lol
48:08 <desu> didn't gentoo stop doing 32 bit
48:11 <desu> arch*
48:24 <rust_collector> yeah, they did, at least for a while
48:53 <rust_collector> I think someone does a 32 bit version now
49:39 <desu> yeah i found that
49:44 <desu> but not the real archlinux ppl
49:57 <desu> https://pacbsd.org/
50:12 <rust_collector> "the real arch people"
50:33 <desu> well
50:35 <desu> the original
50:39 <desu> whatever you know what i mean
50:54 <rust_collector> yeah, you also think they are not actual people
51:12 <desu> i do
51:19 <rust_collector> WHY?!!??
51:20 <desu> what makes you think that?
51:50 <rust_collector> my brain
52:28 <rust_collector> so, you are saying you do believe they are real people? that is something
52:41 <desu> maybe
52:43 <desu> depends
52:49 <desu> i don't really know anything about the arch devs
54:04 <rust_collector> neither do I. I am not very interested in arch. I find it annoying. But that is just me
56:43 <desu> maybe
56:50 <desu> i sort of liked arch when i was younger
57:12 <desu> not so much anymore because of systemd
57:14 <rust_collector> eh? when did you get old?
57:18 <rust_collector> right
57:44 <desu> i guess last year
57:49 <rust_collector> oh ok
58:01 <desu> oh no i didn't use arch for that long
58:08 <desu> but that's when i became a adult
58:31 <rust_collector> mmhmmm
