01:09 <Ysjoelfir> nice K :) I think there is nothing special to the procedure, so that should do it. thanks :D
01:46 <K> i did not watch the video sry
02:17 <K> but from what little i konw about cake-baking, it makes sanse
02:26 <K> cominc-sanse, even!
02:35 <K> ffs my fingers
03:02 <Ysjoelfir> but I did. It seemed pretty streight forward. beat eggwhite with white powder, add walnuts, flatten and bake. make cream: cook until thick, add cocoa and butter, done
03:12 * Ysjoelfir untangles K 's fingers
04:36 <K> btw anyone here wants a xmas postcard? printed some extra this year
05:35 <rc-garage> hmm, it would be a change from the bills and junk mail...
05:40 <Ysjoelfir> do you send paper cards? how nice, I love that :D
05:54 <K> i do
06:02 <rc-garage> very retro
06:15 <K> i just hate trees
06:28 <Ampera> damn straight
06:34 <Ampera> fuck those woody ass motherfuckers
06:37 <Ampera> fuck em right in the wood
06:38 <Ampera> with wood
06:40 <Ampera> their own wood
06:54 <Ysjoelfir> If you have 2 spares I/we would love one. And my grandma. she's probably very alone over christmas and would be very happy to get cards.
07:36 <K> um, i can send you two, one blank
07:45 <K> will that do?
07:53 <K> or do you want me to send a card to your grandma?
08:36 <Ysjoelfir> that would be very cool. She can read english :D
10:38 <Ampera> I wish my grandmother could
10:48 <Ampera> She can read it, just can't understand a word of it
10:57 <Ysjoelfir> why?
11:13 <Ampera> She never learned it?
11:26 <Ampera> what other reason would there be

11:33 <K> dang nabbit
12:00 Nick: K is now known as K``
12:12 <Ampera> use Kalium
12:16 <Ampera> that'd be a neat nick
13:29 <K``> nah, i'll just go with my ircnet nick
14:51 <Ampera> 3 feet might have been a bit optimistic
14:56 <Ampera> I actually think we're getting even more snow
15:34 <K``> no snow here boss
15:54 <Ysjoelfir> send some over plx
16:00 <Ampera> you can have fucking all of it
16:03 <Ampera> we don't want this shit
16:27 <K``> anyone else wants a card? T3sl4 Ampera rust_collector ?
16:31 <Ampera> I'm good
18:19 <Kuschelpony> wow https://www.visaton.de/de/produkte/chassiszubehoer/tieftoener/ws-25-e-8-ohm
18:42 <Kuschelpony> the last time i measured second hand woofers with an Qel of about 1,5 i thought the magnets had been damaged
19:04 <Kuschelpony> here they have from factory ones with again half the strength
19:19 <Kuschelpony> (its an odd outsider of Visatons otherwise good products)
38:07 <rust_collector> I just noticed that the screen out in the garage has speakers built in. which is yay, because then I can remove the other speakers
39:19 <Ysjoelfir> woohoo! music while working!
40:38 <rust_collector> eeh, nah
40:54 <rust_collector> but I can, I guess
42:12 <rust_collector> I wonder what kind of wire I need for that. but I guess that is a thing for... after I am done with this other crap
45:59 <rc-garage> ok, so I tried to look behind there, but there is so much crap stacked up on all the wires... maybe some other day

04:26 <Ysjoelfir> hahaha :D
08:15 <Ampera> hahaha, neither my county nor city has declared any sort of snow emergency
08:35 <Ampera> probably because nobody gives a fuck and aren't gonna be plowing jack, fucking, and/or shit
16:18 <Ysjoelfir> you should ask rusty if that is a snow emergency you have :D
16:59 <Ampera> what makes it funny is almost every single other county and city and town in the area has declared something
17:18 <Ampera> but my city is home to who give a fuck, if you don't like the snow just drive around it
17:57 * Ysjoelfir immagines some random mr. county director standing on a pile of snow, in formal dress, saying: "With this I declare that we have..... something!"
21:16 Join: TheDude ([email protected]) to #EEVblog
21:25 <Ampera> hi TheDude how are you
22:17 <rc-garage> yeah, if that was here, they would declare that there is snow.
22:22 <TheDude> hey
22:28 <TheDude> slightly disappointed
22:38 <TheDude> was hoping I could go buy an SD card today
22:46 <TheDude> only to find that section of the store taped off
23:11 <rc-garage> because of viruses, we are no longer allowed to sell sd cards
23:18 <coppice> Ampera: is a snow emergency in New York when Wall St runs out of coke?
24:14 <Ampera> I find that stupid, you're already at the damn store :P
24:49 <coppice> Ampera: you want sense? note the scum out
24:52 <coppice> vote
26:53 <Lord_of_nothing> hey guys
27:10 <Lord_of_nothing> i feel sssoooo sleepy
27:57 <coppice> then sleep
28:52 <rc-garage> that is often a good option
33:26 <rc-garage> heh, i found my old police radio thing. i wonder if it is usable for anything now
35:04 <coppice> rc-garage: one of the olde worlde analogue contraptions from the dark ages?
36:06 <rc-garage> yeez
36:29 <coppice> for engineers gave the police the digit
37:09 <rc-garage> the police just went to digital a couple years ago. they still use analog a bit, especially when they are more than 15 meters from the office

39:49 <Ampera> snow update
43:31 <rc-garage> yep, still snow
43:53 <rc-garage> 100% new and good quality
44:35 <Ysjoelfir> I still want some of that over here
49:23 * Ysjoelfir is now watching russian cooking videos and wants all that delicious looking food
50:36 <coppice> Ysjoelfir: 1001 variants on borscht?
51:00 <Ysjoelfir> haha :D
51:05 <Ysjoelfir> no. this one https://www.youtube.com/watch?v=eExVYG2QI48
51:26 <Ysjoelfir> 7 different simple recipes. they al look delicious.
52:24 <coppice> I assume this is from the most Eastern parts of Russia
52:40 <Ysjoelfir> I dunno?
53:46 <coppice> interesting that its so sticky they put cling film on the sushi mat
53:58 <TheDude> bruh
54:11 <TheDude> I've looked at the webpages of like 10 stores
54:41 <TheDude> either they don't allow personal pickup, they're closed or they don't have shit in stock
54:51 <TheDude> this is fucking ridiculous
54:57 <TheDude> all I need is a bloody SD card
55:03 <Ysjoelfir> yep. I first thought that it is just store bought dough for potato dumplings, but I think its maybe just very long mashed mashed potatoes? if you mash them long enough they get sticky as fuck
55:03 <TheDude> this shouldn't be this fucking hard
55:29 * Ysjoelfir has a shitton of SD cards but no real use for them
55:37 <TheDude> I just need one :(
55:43 <TheDude> well, microSD, but w/e
55:51 * Ysjoelfir hands one
56:06 <TheDude> thanks, I'll be in Germany in a jiff
56:13 <Ysjoelfir> great :)

17:30 <Guri22> Really Impressed by EEVblog
19:05 <Kuschelpony> welcome to the chat
19:51 <Guri22> I have a problem. While using MAX7219 based 7 segment display module I experienced noise issues on 5v power rail with peak to peak voltage of around 200mV. Can isolating the display using DC DC isolated converter like B0505S solve this problem?
20:37 <Guri22> I am EE undergrad and working on a project that uses MAX7219 based 7-segment display.
22:20 <arch> what topology are you using for that regulator? and what freq is it running at
22:36 <K``> what kind of noise?
23:06 <K``> if it is just ripple, then how about adding some buffering caps?
23:15 <K``> (more buffering caps)
23:18 <arch> or a small post LC filter
23:20 <Kuschelpony> hmm, PWM means major current pulses, and when then there is significant impedance from the bulk capacitor that means voltage ripple
23:27 <Kuschelpony> as K said
23:41 <Kuschelpony> add more buffer caps, and add them right at the MAx supply and GTND pins
23:50 <Kuschelpony> some hundred �F should do
24:39 <arch> if you're multiplexing, freq of the pulses might be pretty high. i think ceramic caps with values of 100nF, 1uF, and 10uF combined will be more than enough. dont think you need hundred+ uf
24:50 <arch> parallel those diff value ceramic caps
26:33 <arch> also, LED displays use buggerall current, so that 200mv ripple might be your smps itself. what's the ripple directly across the smps output cap(s)?
27:16 <arch> boost converters in DCM mode (low current) have higher ripple, especially if the regulator has "eco mode" or pulse skipping mode
30:02 <Guri22> Thanks a lot to all of you! for responding to my question. Actually I am working on a breadboard and have place 100nF capacitor on both rails as well. The frequency of pulses is around 4 KHz. The noise dies out instantly after removing 7-segment display. Maybe a LC filter might help. Actually I am using it as a display for function generator based
30:03 <Guri22> on AD9833. The noise in 5V rail causes huge amount of distortion in output. Even when I powered Display from separate supply. Noise(although reduced) gets introduced to the previous supply used to power Atmega 328p and AD9833 somehow though common GND?!
31:21 <arch> can't expect breadboarded to perform well. if you have the time, you should etch a copperclad PCB instead
31:46 <arch> most likely you have ground loops, and ground bounces due to the large resistances and inductances in wires
32:35 <Kuschelpony> ouch, good luck on the breadboard
33:38 <arch> although, if you have a nice breadboard, like the 3M breadboard, those have a ground plane, so you can get pretty decent performance with those
33:54 <arch> good luck if you have those cheapo chinese/ebay perfboards though :D
34:01 <arch> err breadboards
34:56 <Kuschelpony> back in the years when i used breadboards, that was before the chinese cheapies but also before 3m had a groundplane,
35:41 <Kuschelpony> i cut them in some smaller parts and placed them on a bare PCB as ground plane, also adding some rows of directly to the groundplane soldered contacts in between
35:58 <Kuschelpony> but today i work only in SMD
36:26 <arch> word, so much more convenient
36:57 <K``> Guri22: try adding more caps
37:09 <K``> 100nF seems low
37:15 <Guri22> I am designing PCB on kicad alongside. But the problem is in India parts are costly and difficult to source and sadly I have already fried AD9833 module yesterday even without realizing what actually damaged it. Thanks for explaining me, I'll finish up PCB design part.
38:56 <Guri22> I have plugged in 470uF too but problem remains. Can using jumper wires reduce noise problem?
39:42 <Kuschelpony> hmmm, i worry that you have deeper issues about how to seperate LED supply and return currents, from a "clean" analogue reference and 0v reference
40:01 <Kuschelpony> im afraid that i can not easily give more simple ideas
40:32 * electrohead lights all snow on fire
40:41 <electrohead> >:|
40:50 <electrohead> that's all I have to say.
41:26 <Ysjoelfir> instead of ragequitting you could also just bring it over as I already suggested to ampera like a hundred times! and while you're over, take that rain-thing with you please.
42:00 <Ampera> electrohead, you want more?
42:01 <Ampera> stop complaining
42:04 <Ampera> otherwise you'll probably get it
42:12 <Guri22> No problem at all. Although when substituting MAX7219 with I2C 1602 LCD, noise is negligible. Thanks a million to all of you!
42:46 <Guri22> But 7-segment displays are pretty to look at rather than plain 1602 LCD
43:05 <Ysjoelfir> I prefer VFDs though :D
44:32 <Ampera> VFDs are very nice
44:32 <Kuschelpony> hmmm, Guri, i have some ideas how to make that AD chip on a totally seperate module
44:54 <Kuschelpony> VFD are my favorite displays as well, but LED 7-segment are next as well
45:11 <Guri22> Please can you tell me about them?
45:25 <Kuschelpony> as a side question, do you know if these midsize 7-segment VFDs without integrated electronics are still made?
45:59 <Ampera> I doubt any VFDs outside of PoS system displays are still made
46:02 <Kuschelpony> Guri, thats Vacuum tube technology, where you have a electon emitting filament wire, control grids and anodes coated with luminous paint
46:06 <Ampera> even those are probably largely being replaced with LCDs
46:07 <Guri22> I have seen VFD once in some old music player. But they are available on mouser website
46:44 <Kuschelpony> they give a beututful greenish blue color and have superb contrast, also you can get special colors as well for symbols
47:06 <Kuschelpony> ah i still have some recycled from unrepairable video cassette recorders
47:25 <Kuschelpony> used one for a clock but the others have not the best useable combination of segments
47:41 <Ysjoelfir> you can build a nice tube amplifier with those
47:53 <Ysjoelfir> gives interesting visual effects as well :P
48:03 <Kuschelpony> when we still had medium wave radio, i built an receiver with them :)
48:07 <Guri22> That seems interesting!
48:38 <Ysjoelfir> I have two boxes full of NOS segmented dot matrix VFDs from my ex employer
48:42 <Kuschelpony> but for triode mode with control by a negative grid i needed to go to 90V anode voltage
48:51 <Kuschelpony> ooh nice collection
49:04 <Ysjoelfir> some Noritake Itron and some Futaba IIRC
49:33 <Kuschelpony> hmm, my collection is slmost all Futaba and some no names, never saw a Noritake myself
49:33 <Ysjoelfir> they were used in an 80s product of mr. ex employer which got discontinued decades ago. when they wanted to throw out the remaining VFDs I grabbed those
49:44 <Guri22> That seems quite a lot of work to get them working with arduinos IG. Me a noob working at 5V or maybe 12volts
49:54 <Ysjoelfir> let me take a pic of the devide with the VFD. its pretty a pretty usefull display
50:40 Part: Guri22 ([email protected]) from #EEVblog
50:49 <K``> vfds are nice
50:52 <Kuschelpony> for normal lighting operation you need something 20 to 30V but 12V already gives good light
51:00 <Kuschelpony> oh too late :(

52:46 <Ampera> electrohead, you can let it out on the snow with a shovel >:D
54:18 <Guri22> This was my first experience chatting here! Really amazing! Good Bye!
54:23 <Kuschelpony> snow... we have almost spring temperatures here
54:29 <Kuschelpony> welcome back Guri
54:52 Part: Guri22 ([email protected]) from #EEVblog
55:02 <Kuschelpony> i give up...
55:19 <electrohead> Ampera: yeah I tried to, haha
55:31 <electrohead> what was guri's issue?
56:12 <Ysjoelfir> Kuschelpony thats the device https://drive.google.com/file/d/1kQYf7MUrGCIPSViGzDP0XCUqOS8JCLff/view?usp=sharing
56:25 <Ampera> electrohead, I did my back and then said fuck it
56:43 <Ampera> the dumb ass city isn't plowing the streets anyways, like hell is the mailman getting here
57:24 <Ampera> not unless they start fitting plows on those grummans
57:32 <Ysjoelfir> and the white styrofoam boxes are the displays. Top two boxes are those ones, the PM190 labelled one are like a bargraph style VFD https://drive.google.com/file/d/1kOTndTupbv3hTIhLbyXqkYfZPpyQ_kh-/view?usp=sharing
57:34 <Ampera> and watching as they shit their pants harder than they do already
58:54 <Ampera> looks like the snow stopped though
59:13 <K``> ahh, that vfd is so nice
59:49 <Ysjoelfir> isn't it?

54:21 <arch> Ysjoelfir, "Barbecue Bible"... nice
54:43 <Ysjoelfir> Ampera, I'll install manjaro or however that was called on an old notebook later. if that works good I'll install regular arch on my new NAS hardware.
54:49 <arch> and is that a desktop with a turbo button?
54:57 <Ysjoelfir> heh, yes, thats a gift from my spouse arch :) it is very nice
55:13 <Ysjoelfir> huhu? wait. let me check what you see there
55:19 <arch> https://drive.google.com/file/d/1kOTndTupbv3hTIhLbyXqkYfZPpyQ_kh-/view
55:38 <Ysjoelfir> ah. no, thats mrs spouses old PC. the button is just the reset button and the LCD displays a temperature
56:35 <Ampera> why would you install arch as a NAS operating system
56:50 <Ampera> I mean it'd work fine I suppose, but it wouldn't be my first choice
57:13 <Ampera> manjaro and arch are also quite different
57:18 <Ysjoelfir> because I wasn't satisfied with freenas or nas4free or whatever, want to have samba shares available and do other stuff on the NAS as well
58:13 <Ampera> Arch is fine for workstation usage, but I'd sooner pick Debian or FreeBSD for a NAS or server
58:47 * arch picks Ampera for the 2020 international homo awards
58:50 <arch> jk
58:59 <Ysjoelfir> that would mean that I have to learn two linuxes :X
59:16 <Ampera> Ysjoelfir, you just mentioned learning arch and manjaro
59:29 <Ampera> you're already learning two
59:35 <Ysjoelfir> the base system of manjaro is arch, isn't it?
59:40 <Ampera> no
00:14 <Ampera> Manjaro uses /some/ of the same tooling as arch, but has a completely different release and packaging philosophy, and mutually exclusive repositories
00:27 <Ysjoelfir> pfffffffffffff....
00:46 <Ysjoelfir> why did I exactly want to learn linux? was I realy THAT unsatisfied with windows...
01:01 <Ampera> you're asking me?
01:05 <rc-garage> yes, you was
01:20 <arch> i just wanted to be one of those movie hax0rz by running a terminal session
01:25 <Ampera> Linux distros are different for a reason
01:30 <rc-garage> nas? do you want gui things on it?
01:38 <Ysjoelfir> yes
01:55 <rc-garage> ok, then I have no suggestions
01:56 <Ampera> I have X on my server, though I never use it
02:19 <Ampera> the main purpose for a UI, in my opinion, is to make local management easier
02:28 <rc-garage> yep
02:34 <Ampera> but not so you can have things done for you, if you want a linux/unix server you're still gonna be setting things up yourself
05:27 <rc-garage> Just because I am me, I would suggest debian stale for a nas. yes, it is boring. as long as your machine does not have all the superfancy new things, it is fine.
06:54 * Ysjoelfir is sitting in a corner and cries
07:40 <rc-garage> get used to that feeling
07:52 <Ysjoelfir> I am
08:02 <rc-garage> good, then get going
08:55 <rc-garage> go go go!
09:12 <Ampera> CRY >:D
12:50 <Ysjoelfir> I do
17:48 <rc-garage> CRY HARDER!!!
18:43 <Ysjoelfir> the room is already flooded
19:14 <rc-garage> that should make it easier, no?
19:37 <Ampera> I wanna see water pressure dammit WATER PRESSURE
19:47 <Ampera> I SHOULD BE SEEING REPORTS OF A FLOOD IN GERMANY HERE
20:10 <Ysjoelfir> yes
20:34 * Ampera smacks Ysjoelfir with a bottle of calcium carbonate tablets before belching concentrated HCl at him
21:29 <Ysjoelfir> I already cried a lot today, so thats fine I guess
22:25 <Ampera> I probably haven't cried proper in a year or two
24:35 * T3sl4 hugs Ysjoelfir

10:00 <T3sl4> your nuts
10:15 <Ysjoelfir> no, regular ones
37:56 <Kuschelpony> and T3.... i just wanted to thank you for your verywell written explanation on https://www.eevblog.com/forum/projects/push-pull-transformer-driver-design/msg3374704/?topicseen#msg3374704 a week ago
38:48 <T3sl4> you're welcome :)
39:10 <Ysjoelfir> T3sl4 writing well written explanations? :O I thought he is only open to spamming ;P
41:19 <T3sl4> spam is in the eye of the bereader
42:05 <Ysjoelfir> :P
42:14 <Kuschelpony> well, i also deal and sometimes design magnetic components and small switchmode converertters so i know that just right, but i also cry so often about all the shit that is elsewhere on the web wehre peopel totally misinterpret that stuff
46:20 <Ysjoelfir> that might be because learning magnetics is a pain in the ass. ofc depending on who teaches you, but I think its a topic that is hard to explain in a... interesting and understandable way.
47:47 <Kuschelpony> i never learned it from anyone
48:11 <Kuschelpony> instead developed all myself from first principles
48:52 <Kuschelpony> that way i understood for example aslo why the energy storage of a given ferrite core is exactly proportional to the volume of the air gap
49:25 <Kuschelpony> but i am happy to see that its today more understood by more people and them posting in forums as well
50:10 <T3sl4> same here, more or less
50:35 <Ysjoelfir> I learned very much about magnetics when I wrote my bachelors thesis about developing a method to dynamically measure saturation of low frequency power inductors. It was VERY interesting, but I still don't know nearly as much as I would like to
54:06 <Kuschelpony> right
56:14 <T3sl4> i did that a while ago, just a pulser, basically wire up a supply, MOSFET, sense resistor and function generator
56:24 <Ysjoelfir> which is one reason I want to go deeper into that field in my private studies when I have a bit more time. Had to stop at a rather interesting point where I was researching parasitic effects in my measurements, because mr. ex employer wanted me to continue with "more profitable" tasks.
56:27 <T3sl4> call it saturation when the current ramp starts to bend upwards
57:32 <T3sl4> at such point, you know saturation is current related, but it's real nice to actually move around the core pieces and see that the time to saturation doesn't change (much), just the current scaling vertically
58:01 <T3sl4> which proves it's turns, core cross section, and Bsat, that's setting saturation, and air gap stores energy, etc
58:33 <Kuschelpony> whicxh can be very easy explained by the fact that flux density is related to volts*seconds/squaremeters
58:51 <T3sl4> Ysjoelfir, for your next employment opportunity you should condition it on either additional college training, or certain freedoms to do basic research in the lab
58:54 <Ysjoelfir> T3sl4 that is one of the industry standard methods, yes. the other one being adding a big DC to the inductor which is decoupled by two waaaaay bigger indictors from the PSU. My method involved measuring the inductance in very small stepy while slowly cranking up the current. this allows you to plot a very nice L/I curve.
59:22 <T3sl4> ah, the small signal inductance
59:37 <Ysjoelfir> well, with the new employer I'll be doing PCB design all the time, so no research work will be done there whatsoever
59:47 <Ysjoelfir> well, "small".... is 60ARMS small?
00:10 <Ysjoelfir> but yes, you can capture it from basically 0 to whatever your equipment can do.
00:27 <Kuschelpony> even more interesting is that core saturation can also be calculated from inductivity and core area without counting the number of turns
00:46 <T3sl4> small signal, the signal is the AC part :P
00:51 <Kuschelpony> maybe this winter in finish my formula collection of magnetics
02:54 <T3sl4> as long as you aren't solving geometry and icky stuff like that, it's pretty easy, just ratios, basic algebra
03:37 <Kuschelpony> right
03:43 <Kuschelpony> and thats why i love the SI system
04:01 <Kuschelpony> 1 Volt * 1 Second / 1 square Meter = 1 Tesla
04:32 <Kuschelpony> much easier than Gauss in Feet
07:57 <Ysjoelfir> T3sl4, the whole signal is AC^^ I wanted to know how the inductor behaves when being powered by high power AC, not DC. Or am I missing something?
08:34 <T3sl4> oh, but then why string it between extra inductors?
09:06 <Ysjoelfir> huh? you must have misread that. the two inductors thing I mentioned was another method I read as being "industry standard".
10:30 <Ysjoelfir> My method is rather simple - variac + step down transformer feeding into the DUT, I and U is measured at the DUT. done.
12:58 <T3sl4> oh, the "industry standard" wasn't elaboration on your project
13:04 <Kuschelpony> historically known as Ferroscope when yoiu watch in XY mode
14:27 <Ysjoelfir> nope. :D
14:53 <Ysjoelfir> Kuschelpony - sounds interesting, but I can't find anything with that name, except some device to measure tubes. have you sources? I would love to read that up
15:35 <Kuschelpony> hmm, i can only reference to sheets of dead trees
16:04 <Ysjoelfir> thats fine for me, I like dead trees
16:15 <Ysjoelfir> have you seen our dead tree collection? :P
16:22 <Kuschelpony> the modern solution with an osciloscope places the integral of the voltage (an looow pass RC does it) on one channel and the current on another channel, then you get the magnetizing curce directly on the screen
16:34 <Kuschelpony> oh i have my own cubic meters of them
17:20 <Kuschelpony> i look up for web resources the next days
17:49 <Ysjoelfir> that would be nice :)
19:10 <T3sl4> right, trace the B-H curve
19:16 <Kuschelpony> strange, i think that method was very common
19:26 <Kuschelpony> right
19:40 <Ysjoelfir> Jep, thats the basic idea.
20:34 <Ysjoelfir> when I did the research I looked pretty hard and couldn't find anything. my university professors haven't heard of the method either, so I am very curious to learn more about it now :D
20:54 <Kuschelpony> oooof
21:32 <Kuschelpony> well thats embarassing to hear that the most basic history known method to automatically plot the curve is so rarely known
22:54 <Ysjoelfir> not realy, in our university there were very few professors that knew much about historical methods. some even don't know how a Twooooob works
25:25 <coppice> Ysjoelfir: do they think high power transmitters, and satellites work by magic?
25:40 <Ysjoelfir> yes!!!!
25:41 <Ysjoelfir> no
25:51 <Ysjoelfir> they just don't care if its not within their specific spectrum
26:50 <Kuschelpony> hmm, i can not comment about how university professors work, but i can say i learned most by reading some well written books from 50 to 100 years ago and refined the principles i saw
27:07 <Ysjoelfir> I totally agree about that
27:16 <Ysjoelfir> one of the best books I ever read was... erm... wait a sec
27:21 <Ysjoelfir> or better, two
28:00 <Ysjoelfir> or one and one series >_> the first one was this one: https://drive.google.com/drive/folders/17bptOw_UxtxRG4JNZ2k28GgZ1eISak1t?usp=sharing
28:33 <Ysjoelfir> and the second one was the book about tubes from Heinrich Barkhausen
28:37 <Ysjoelfir> *books
28:58 <Kuschelpony> hmm, i still have blocked Google and do not plan to change this
29:16 <Kuschelpony> but the tube book from Prof. Barkhausen, at leats part one, is just 30cm next to me :)
29:34 <Kuschelpony> plus lots of other old stuff i like to read in the night when i cant sleep
39:51 <T3sl4> RDH4 is a classic, and still quite useful, if you adapt the toob stuff to FETs say
40:21 <Ysjoelfir> RDH4?
41:28 <T3sl4> radiotron designers handbook
41:47 <coppice> T3sl4: the cools tubes, like TWTs and magnetrons, won't adapt well as FETS
42:09 <T3sl4> i don't think you'll find those in RDH4
45:54 <Ysjoelfir> Kuschelpony - extra for you i uploaded it to my webspace :P well, and because I think that book is just gorgeous. http://img.pdi.engineering/forums/dead%20trees/die%20elektrizitaet/
47:16 <Kuschelpony> ooh thanks
48:13 <Kuschelpony> i read tons of that stuff in the PDF versions of the "Zeitschrift f�r Elektrotechnik"
48:25 <Kuschelpony> www.archive.org :)
48:52 <Kuschelpony> should one day get an e-book reader, thats more convenient than the laptop on long train tours
49:06 <Ysjoelfir> oh, nice :D didn't know that one yet
50:36 <Kuschelpony> prepare for some 5k pages for the time span from the late 1880s to 1905
50:49 <Ysjoelfir> .........
50:59 <Ysjoelfir> I wanted to get more into reading anyways :D
51:02 <Kuschelpony> and you will see the development from the crazy stuff to the machines you woulkd even today use
51:05 <Ysjoelfir> or better.. get back into reading more.
51:31 <Kuschelpony> one weird example was the "System Thury"
52:01 <Kuschelpony> think about a constant current circuit, with 80 Amps at upto 10 kilovolts, that in a ring around the town
52:19 <Kuschelpony> when you needed to run a motor you connected it in series to this ring
52:32 <Ysjoelfir> well.... I can see the benefit, but.... :D
53:08 <T3sl4> i don't think we ever did anything quite that dangerous, but some cities still have a CC loop for street lights, something like 2kV and about that many amps
53:16 <Kuschelpony> on the positive side, you had no issues with inrush current
53:37 <T3sl4> apparently the transformers have the secondary mounted on a counterweighted arm, so the lorentz force against it pushes it away from the primary, reducing flux
53:53 <T3sl4> well, sort of... that mechanism has inrush due to arm inertia ;)
53:56 <Kuschelpony> but there are reasons why AC and transformers running on constant voltage quickly got more poplar
54:02 <T3sl4> indeed
54:12 <Kuschelpony> well that mechanical transformers, i have also seen them...
54:17 <Kuschelpony> ingenious
54:27 <Ysjoelfir> naaaaaah. thats just details and good lobby work from the AC lobby ;P
54:49 <Kuschelpony> and the inrush was no problem, before switchignthe primary on they were retracted to minimum current and then swung into equilibrium
56:40 * electrohead bops in

01:16 <electrohead> I'm alright, winding down finally, done with all the shoveling, done trying to help with a partially flooded bathroom at work.. yay
01:27 <Ampera> nice
01:42 <Ampera> the stupid city hasn't plowed our street
02:05 <electrohead> still?
02:07 <electrohead> damn
02:23 <Ampera> they've put actual millions into redeveloping downtown and the riverfront, but can't pay a penny for a few trucks with shovels on them
02:54 <Ampera> it was exactly like this last year, when the national guard was plowing our streets because the city couldn't be fucked
03:13 <electrohead> well that's fucked
03:33 <Ampera> I'm not sure if it's still the case because I rarely am driven anywhere, but it was last year that they never paved any roads either
04:02 <Ampera> the sidewalks are fucked all over town too, and they don't do jack shit about those either
04:42 <Ampera> and I don't get it, they've gotten millions in investment and none of it has benefited anyone. Nobody's even occupying the newly developed areas they've made up
05:30 <coppice> Ampera: isn't corruption wonderful?
08:46 <T3sl4> don't you know? trickle down economics works, all the diarrhea the rich people have from feasting on that money trickles down onto us
08:52 <T3sl4> we should be gracious
14:02 <coppice> we all know trickle down economics is just taking the piss
27:36 Join: Kaami1984 ([email protected]) to #EEVblog
28:12 <Kaami1984> hi guys, I have just 1 question - can I buy uSupply somewhere ?
29:29 <rust_collector> last time I looked, they were sold out. I really do not know
29:29 <Ysjoelfir> was that thing even ever finished?
29:55 <rust_collector> ah, right, that was not that thing, it was the ucurrent thing
30:15 <rust_collector> no, I don't think the supply was finished
30:48 <Kaami1984> I wonder why...
31:20 <Ysjoelfir> IIRC it had stability issues due to poor component choices? T3sl4 might remember?
32:50 <Kaami1984> I was trying to build something similar on LT308x and... I don't think CC+CV on single regulator is good idea.
33:25 <Kaami1984> it is easier to clone some HP/Agilent supply output circuit
33:50 <Kaami1984> there are service manuals with all schematic
36:46 <Ysjoelfir> I agree with that.
37:20 <rust_collector> I don't really remember what the idea of the usupply was... I guess cloning an hp would be pretty safe. but it looks a bit more involved than using a regulator ic and an opamp or two
37:34 <rust_collector> maybe I am just too much of a noob
38:26 <Ysjoelfir> I think it started with dave wanting to show how "easy" it is to design a power supply, which resulted in him adding loads of stuff around a regulator that wasn't realy suitable for the project in the first place, and the whole thing just evolved into a mess
38:34 <Kaami1984> LT308x is a "black box", much harder to use in cc/cv scenario
38:44 <Kaami1984> :D
39:24 <rust_collector> as long as you select the black box that makes a neat little power supply, with cc/cv, I do not see a problem with them
39:29 <Kaami1984> some transistor would be better for that
39:59 <Kaami1984> I mean transistor pair
40:22 <Ysjoelfir> I think in the end he is using the LTsomething basically more or less just as a power transistor. A pretty shitty one though
41:05 <Ysjoelfir> I never finished the series though
41:23 <Kaami1984> I wasted about 1 week trying to make cc/cv supply with LT3083... I could make money in that week and just buy used tektronix or hp supply
41:46 <Kaami1984> not portable, but... I dont care about that
42:48 <Kaami1984> I'll wait for new digilent stuff. I have Analog Discovery 2 which is awesome, and now they are working on something similar, but with better power supply.
43:23 <Ysjoelfir> true. I build some PSUs in the past, but in the end I ended up using premade ones that are just better and already tested to work under all cases. The time I would need to invest to develop a rock solid one that could replace at least 2 of my three PSUs would take me much more than what the space on my desk is worth^^
56:43 <rust_collector> hmm, now it looks like I have to go up north anyway. I was hoping I did nto have to
56:48 <rust_collector> oh well
57:03 <Ysjoelfir> I thought that was already decided that you need to go there?
57:55 <rust_collector> it was, then she was taking a plane here, to pick it up, but now she is not again. i dunno?
58:28 <Ysjoelfir> lol
59:04 <Kaami1984> im going to work, cya guys
59:10 <Ysjoelfir> https://www.youtube.com/watch?v=1D_AOIdbFAw watching that right now. I would so enjoy to have such a workshop and make it useable again
00:27 <TheDude> https://www.imdb.com/title/tt10310140/
00:30 <TheDude> just watched this
00:40 <TheDude> surprisingly entertaining :3
01:07 <Ysjoelfir> not sure if that sounds entertaining to me :D
01:21 <TheDude> it's a christmas movie
01:29 <TheDude> just not absolutely shit, like most of them

38:11 <Nothing\> <begin communication>
38:24 <Nothing\> greetings fellow earth humans
39:26 <Nothing\> i found one of those brain training games that actually has peer reviewed studies backing up its effectiveness. unlike all of brain training type games.
39:29 <Nothing\> http://brainworkshop.sourceforge.net/
39:35 <Nothing\> dual n-back
39:58 <Nothing\> sounds simple in theory but holy crap does it require a lot of focus
40:28 <coppice> Nothing|: note the peer review isn't what it used to be
40:50 <Nothing\> coppice, well thankfully this paper was from 2008
41:17 <Nothing\> but yeah, you can literally buy the ability to publish an article in a "peer reviewed journal" these days
41:44 <Nothing\> i remember hearing a few years ago about a group that was doing that
42:10 <Nothing\> for something like $100 you could get your article published and it didn't matter how peer reviewed or scientific it was
42:42 <Nothing\> forget the name of the group, it started with an O and of course they were based out of India
43:05 <coppice> It claims improvements in short term memory, and fluid intelligence. The former is quite possible. The latter is unlikely. Being able to improve general a general performance parameter using limited tasks is hard to imagine working out well
43:35 <Nothing\> actually i watched a video on medlife crisis a while back about underground markets that sell human bones and other remains illegally
44:03 <T3sl4> beep boop
44:07 <Nothing\> i remember back several years ago you could buy legit human skulls on ebay for a couple thousand dollars, but they don't allow that anymore
44:10 <Nothing\> hey T3sl4
44:13 * Nothing\ hugs T3sl4 
44:15 <Nothing\> <3
44:21 <T3sl4> *nothingly hugs*
44:55 <Nothing\> coppice, yeah tbh it's been some time since i read that paper
45:06 <Nothing\> were you able to determine the sample size?
46:34 <Nothing\> i was just thinking about doing my own impromptu experiment where i'd play this game, along with a couple of other "brain training games" basically just for the cognitive/memory/focus challenge and to get some metrics to measure those by, roughly at least
46:55 <Nothing\> doing that for i dunno, a few weeks or so and seeing what sort of improvement i make
47:56 <Nothing\> then taking this so-called "smart drug" called noopept that's supposed to improve those very qualities of one's mental state and then start over again with new brain training games so any retained skills don't get in the way
48:14 <Nothing\> and see if there's any noticeable effect on how quickly i improve
48:47 <Nothing\> tbh i've noticed little effect in my day to day life taking it, but it did seem to help a mild to moderate amount when i was learning to play piano
48:56 <Nothing\> but it's hard to say really
49:22 <Nothing\> it's actually sold in russia as a medication for dementia, i believe
50:13 <Nothing\> but there's still a lot of research to be done on nootropics like that. the implications are rather tantalyzing.
53:07 <Nothing\> i remember reading about ampakines in scientific american back in the early 00's and even that got me excited. Drugs where you could stay awake for days on end and still remain perfectly alert without adversely affecting you or causing psychosis like amphetamines do.
54:45 <Nothing\> perfect for airforce pilots and truckers alike lol

51:31 <arch> im thinking of making my own raspberry pi POE hat using UC3843. not sure if it's gonna be over my head tho
55:49 <T3sl4> he's just a PoE boy
00:20 <Nothing\> arch, the best way to make yourself a better person is to push yourself beyond what you're comfortable with
00:28 <Nothing\> even if you fail, you'll still learn something.
00:36 <arch> amen to that brotha
05:09 * steve30 curls up next to T3sl4 
05:20 * T3sl4 pats steve30
14:18 <arch> soooo if i understand correctly, to make a standard PoE compliant design, i need a PoE controller (such as this https://www.ti.com/lit/ds/symlink/tps2376-h.pdf ) and then at the output of it, i just hook up my standard (isolated) flyback or forward smps to convert down to 5V or 12V output?
26:52 <T3sl4> idunno, i havent looked into it
30:32 <arch> well then fuck you. noob.
30:35 <arch> jk
30:39 * arch kisses T3sl4 
31:05 <T3sl4> :3
31:39 <arch> :3
34:39 <Nothing\> lol @ this article about a school resource officer who pawned his service pistol and reported to work with a BB gun
34:54 <Nothing\> you know that guy was on something heavy
35:09 <Nothing\> either that or he was in debt to the trench coat mafia
35:32 <Nothing\> they're real ya know
36:05 <Nothing\> they use doom 2 as a training simulator train teenagers to do school shootings
36:27 <Nothing\> john romero is their kingpin
40:56 * Ampera hugs Nothing\ 
41:11 * Nothing\ hugs Ampera <3
41:16 <Nothing\> how's it going, buddy?
41:18 <Ampera> how are you doing Nothing\
41:26 <Nothing\> i'm doing pretty well
41:30 <Ampera> alright, just had woken up to get something to drink, will be going back to sleep soon
41:41 <Ampera> did you get much snow over there?
41:44 <Nothing\> right on. that's the way to do it.
41:50 <Nothing\> not really. just a light dusting.
41:53 <Nothing\> but it's cold as shit.
41:59 <Ampera> we got maybe 2 feet
42:00 <Ampera> or more
42:08 <Nothing\> wow that's crazy
42:25 <Ampera> our city is craptacular so they also don't seem to be plowing streets
42:33 <Ampera> at least they haven't plowed ours, probably still yet
42:41 <Nothing\> that sucks
42:45 <Ampera> last I checked was around 4PM
42:53 <Nothing\> last city i lived in, they even had plows for the sidewalks
42:58 <Ampera> last year it got bad enough they had the national guard plowing the streets for them
43:37 <Nothing\> which is kinda scary when you're walking along and a sidewalk plow comes along in the middle of the night and you're wearing headphones and can't hear it come from behind you.
44:02 <Nothing\> Then there's nowhere to go but into the knee deep snow beside the sidewalk to let it pass
44:38 <Ampera> lots of people don't shovel their snow, and nobody's gonna clear it for them
45:00 <Nothing\> that too, or clearing icy walk ways
45:10 <Nothing\> ice is such a bitch
46:21 <Nothing\> a couple of years ago my cousin broke his leg slipping on ice and had to get all sorts of pins put in it to put it back together and what not. Took him like a year to heal almost completely
46:56 <Ampera> the governor made ice illegal, so it's impossible for the sidealks to be icy because it's illegal
47:22 <Nothing\> so, what they just cover everything in salt?
47:29 <Ampera> no, they made ice illegal
47:34 <Ampera> so it doesn't exist anymore
47:59 <Ampera> if you try to freeze water you will go to prison
48:04 <Nothing\> oh so they hired that guy from cat's cradle and turned it all into ice-9
49:31 <Ampera> what the governor actually did do recently is make it illegal to sell or display certain hateful flags and imagery on state property
49:37 <Ampera> so confederate flags, swastikas, etc.
49:45 <Ampera> rather, the state government
50:30 <Ampera> which isn't constitutional, and should never hold up in a court of law past the courts of the state, but I guess people like to ban displaying unstately thoughts anyways
50:58 <Nothing\> huh, according to my count there are at least 19 different forms of ice
51:34 <Nothing\> Ampera, that seems to come close to impinging on first amendment rights
51:48 <Nothing\> since state property is public property
51:53 <Ampera> indeed
52:17 <Ampera> I don't know the limits of state property, it's possible that's literally just state buildings and some parks, or every public space
53:28 <Nothing\> yeah that's the tricky bit
53:30 <Ampera> I don't get the mind of whoever makes those laws, like that's goining to A. stop anyone B. make people not have stupid opinions
54:26 <Ampera> it is like making ice illegal, people are going to have and proliferate shitty opinions anyways, you're just now giving precedence for someone to choose what counts as a shitty opinion in the eyes of the law
55:26 <Nothing\> or when Italy prosecuted those scientists for not being able to successfully predict an Earthquake that killed people
55:38 <Ampera> wha
55:45 <Nothing\> which they never claimed they could do. no scientist ever would.
56:07 <Ampera> I've never heard of that, so I can't say, but amusing if true
56:32 <Ampera> despite some incredible scientists of our time claiming Italian heritage, you still never think of Italy to be a particularly scientific nation
56:46 <Ampera> artistic, expressionist, musical, culinary, but not really scientific
57:04 <Nothing\> oh good, the convictions were overturned
57:07 <Nothing\> https://www.theverge.com/2014/11/11/7193391/italy-judges-clear-geologists-manslaughter-laquila-earthquake-fear
57:56 <Nothing\> Ampera, it's where newton wrote his principia and invented calculus
58:05 <Nothing\> not to mention da vinci
58:10 <Nothing\> but modern day, yeah not so much
58:28 <Ampera> Italy didn't exist as a nation then though
58:36 <Ampera> Italy, like Germany, is a somewhat modern concept
58:42 <Nothing\> though I know they have a fusion reactor with what i think is kind of a shitty design
59:11 <Ampera> Isn't it that Italy has no rule of double jeopardy?
59:14 <Nothing\> where they just zap pellets of fuel with super powerful lasers to cause fusion for like a split second
59:25 <Nothing\> that i'm not sure of
59:27 <Ampera> I seem to recall that about their legal system, meaning there is no limit to how many times an individual can be brought to court for the same crime
59:41 <Nothing\> that would suck if true
00:10 <Nothing\> okay i'm gonna go eat some ice cream now
00:14 <Nothing\> bbiab
00:29 <Ampera> Ah, that reminds me, there was an edutainment game I played when I was much younger, I believe my dad cloned the CD from the library, it was called Zap! (I believe, I only just looked it up)
00:37 <Ampera> and it contained a fairly simple circuit builder
01:13 <Ampera> https://youtu.be/Oi4tOEF_Bgo?t=186
01:29 <Ampera> I only recall bits of it, but I remember having fun playing around with it
01:44 <Ampera> maybe I'll go hunting for a rip of it some time

54:41 <coppice> Ampera: It took the invention is a biscuit to allow the formation of modern Italy
55:07 <Ampera> coppice, one of us had a stroke
55:24 <coppice> you poor fellow
55:29 <Ampera> lol
56:01 <Ampera> I'm not that well versed in Italian history, I just know it was similar to Germany in that it was invented out of a desire for nationalism
57:38 <coppice> There was a key figure called Giuseppe Garibaldi, after whom a kind of biscuit is named
00:16 <Ampera> he sounds like a right cracker
00:19 <coppice> Ampera: I think most of the German states have long histories. Its their amalgamation into modern Germany that is, er...... modern
00:37 <coppice> Ampera: do you have Garibaldi biscuits in the US?
00:41 <Ampera> isn't that what I just said?
00:48 <Ampera> we don't have biscuits in the US
00:53 <coppice> you might have looked it up
01:21 <Ampera> however, as for cookies/crackers in general, no I don't recall that brand
01:25 <Ampera> or style
02:19 <Ampera> Germany was formed after Prussia, in ailliance with the German states they hadn't eaten yet, and in exception of Austria, went over and noogied France a bit.
02:42 <coppice> Nothing\: are you thinking of the NIF in the US? That is the major installation what fuses fuel pellets with lasers
03:57 <coppice> Ampera: you do have biscuits in America. They are served with a strange white gravy for breakfast
04:02 <Ampera> Looking up Garibaldi biscuits, I've never seen those before, and they would be called crackers
04:26 <Ampera> coppice, I more meant biscuits as you know them, we very rarely have the soft of cookie/cracker kinda concept you have
04:45 <Ampera> I've also never once had biscuits and gravy in my life
04:51 <coppice> we usually reserve the word cracker for something unsweetened. Garibaldi biscuits are both a sweet dough and a lot of sweet raisins
05:42 <Ampera> here cracker can be both savory or sweet (graham cracker for instance), whereas cookie has a broader definition which can include drier things you might call a biscuit, to actual cookies you might bake yourself

02:57 <Halcyon> Hey all
03:17 * Halcyon offers Ampera a Gary Cracker
05:09 <steve30> hi Halcyon
05:13 <Halcyon> Hey Steve :)
05:59 <steve30> I've just been to Tesco, but i've got to go out again later to go to the chemist. And its a miserable wet day.
06:07 <Halcyon> Aw
06:15 <Halcyon> It's been raining and storming here too
06:20 <Halcyon> But also 30 degrees
06:26 <Halcyon> Sp ot
06:29 <Halcyon> So it's muggy
06:39 <steve30> Its 12C here, so not uncomfortable

28:26 <T3sl4> wow, an asteroid (environmental hazard) just hit a missile (enemy fire) in flight (in FTL)
32:06 <Ysjoelfir> nice :D
32:46 <Ysjoelfir> also, mornings all
33:07 <steve30> hello Ysjoelfir
34:27 * T3sl4 hugs Ysjoelfir with a belt of coffee
38:34 <Halcyon> Hey Ysjoelfir and T3sl4
38:50 <T3sl4> hi-lcyon
39:21 <Halcyon> This is what I imagine Ampera to be like if he played piano: https://www.youtube.com/watch?v=I_qHrjsHOcw
39:25 <Halcyon> :P
41:59 <steve30> What's the hosepipe for?
45:57 <DogWomble> Ampera, apparently there are people that think australia is a lie
46:20 <DogWomble> /... and i've jsut ralised i was scrolled back
46:24 <DogWomble> don't mind me, my brain iss mush
47:03 <K``> hello meerkats
47:15 Nick: K`` is now known as K
55:27 <steve30> My hair is getting long again. I don't know whether to leave it and have it long again, or whether to cut it
14:27 <Ysjoelfir> I am not allowed to have it long. SWMBO decided.
22:50 <K> under the thumb!
41:29 <Ysjoelfir> exactly
41:48 <Ysjoelfir> damn, my soon to be NAS hardware is screeching in some high frequency noise >_> damn VGA output
50:00 <K> snip it off
50:27 <Ysjoelfir> well... the GPU has only VGA.
51:04 <Ysjoelfir> also fascinating: I could never immagine that a console based browser works that good :D
31:14 <rust_collector> which one?
32:25 <Ysjoelfir> lynx
37:08 <Halcyon> https://www.youtube.com/watch?v=gmYVyp_gB_o
37:11 <Halcyon> S-M-R-T
37:12 <Halcyon> :P
38:25 <Ysjoelfir> indeed!
39:01 <rust_collector> lynx... well, ok, if you like that
39:30 <Ysjoelfir> Its handy since I can read the installation instruction while doing the installation in another console. also I wonder if the arch bootloader understands "md/v1.x metadata". since I am formatting this disk with the arch thing I assume it should.
43:16 <rust_collector> md/v1.x metadata, eh?
43:41 <Ysjoelfir> no idea what that means ;D
43:57 <rust_collector> that was what I thought as well
44:10 <Ysjoelfir> it just warned me that I might not be able to boot from that drive with that configuration
44:53 <rust_collector> eeeh heh that is always good. I can see some more crying coming up
45:15 <Ysjoelfir> yes!
48:51 <rust_collector> what does your fdisk -l say
50:02 <Ysjoelfir> many things. :D wait
51:14 <Ysjoelfir> doesn't look suspicious to me. it created the raid disk and doesn't say its faulty
51:51 <Ysjoelfir> before it complained that the GPT table of one drive that I added to the array is faulty, but I managed to fix that
52:54 <Ysjoelfir> also, I managed to kill the high frequency squealing noise! Yay to superglue!
55:05 <rust_collector> 8 liters of superglue was all it took
58:17 <K> stupidglue
58:34 <steve30> i've been outside again
58:49 <K> what did you do? poured some over the inductor?
59:20 <Ysjoelfir> I flooded the inductor with it and glued it to the PCB while applying some pressure to it
59:54 <Ysjoelfir> Need to go outside as well soon :(
00:10 <rust_collector> yes, that is a thing
04:56 <K> outside is real?
05:07 <K> no way
05:23 <Ysjoelfir> yes, sadly
05:42 <K> how much is the wilderness-soros and open-sky-gates paying you to peddle these lies to honest, trusting folk?
06:02 <rust_collector> all the it
06:02 <K> (question to rusty)
06:36 <Ysjoelfir> is it beneficial to make SWAP bigger than the suggested minimum 512Mb? (also question to rusty (and whoever knows an answer))
06:46 <K> about 3.50 then, eh?
07:05 <K> in the antique times it was said that swap should be 2-4x times of ram
07:13 <rust_collector> Eeh, if you are going to use a swap partition, you might as well give it some more
07:47 <Ysjoelfir> 2-4 times of ram... ok.
08:11 <K> but that was time of 32-bit cpus and spinning medium
08:12 * Ysjoelfir creates a 128GB SWAP partition, filling 50% of the disk with swap
08:38 <K> how much ram do you have there?
08:44 <rust_collector> "yes"
08:46 <Ysjoelfir> 32Gb
09:06 <K> i doubt you will need swap that much
09:10 <Ysjoelfir> :P
09:27 <rust_collector> give it 2
09:48 <K> otoh it will be some hassle to add it later if you start getting kicked in the teeth by oom
10:06 <rust_collector> you can just make a swap file
10:37 <K> doesnt it have to in one piece?
10:40 <Ysjoelfir> I read I can add additional sweap space to other drives later, so I think that should be fine? this PC will have looooots of dives
10:47 <K> yah
11:10 <K> put swap on some fastish ssd
11:22 <K> or not
11:28 <K> make it suffer!
11:35 * Ysjoelfir has 2 nvme in a raid0 and doesn't realy know what I will do with that
11:36 <rust_collector> yeah, because then it would never swap out at all, lol
15:09 <rust_collector> put them on ebay
15:27 <Ysjoelfir> nah.
22:19 * Ysjoelfir is doing the formatting stuff of the created partitions
22:21 <Ysjoelfir> don't I need to format the EFI filesystem thing?
23:38 <Ysjoelfir> ah. looks like it needs to be FAT32
30:28 <Ampera> good morning
31:40 * Ampera mkfs.vfat /dev/Ysjoelfir's
32:05 <Ampera> now you're even FATter
36:13 <Ysjoelfir> nice!
36:22 * Ysjoelfir is annoyed by having 2 keyboards
36:35 * Ysjoelfir just send "nice!" to the console
37:46 <K> ExFAT or bust!
38:31 <Ampera> ExFAT only exists to be something Microsoft could extract license fees for
38:35 * Ysjoelfir would love to be ex-fat
38:54 <Ampera> I mean I guess that's all of their software really, but moreso than NTFS
05:54 <rust_collector> funf un fun
06:52 * Ampera high funfs rust_collector 
07:22 <K> you filthy funfers should take you funfing outside!
07:39 * rust_collector kicks K
08:17 <rust_collector> sorry, it is the closest I get
09:12 <Ampera> I /could/ give you op so you can fulfill that desire, but that would require me to be a funf guy, so I'm not.
09:19 <rust_collector> I think I have to find my thermos... I am going to need a LOT of coffee
09:36 <Ampera> either that is one big thermos or you have a poor idea of a lot of coffee
10:20 <rust_collector> it is... uhm, 4 liters, I think. it is one of those they used to have on trains/planes, on the little snack trolley
10:40 <rust_collector> That should last me at least half the way
11:34 <Ampera> fair enough
12:01 <Ampera> enjoy pissing like a race horse
12:12 <rust_collector> Oh , I know... lol
12:17 <rust_collector> it is my thing
15:04 <rust_collector> I guess I should bring a phone charger... that could be handy
