12:46 AM rue_house: 75nA!
12:47 AM rue_house: how you supposed to make the battery last?
04:58 AM megal0maniac is now known as shifttymike
07:14 AM day__ is now known as daey
12:07 PM Emil: https://emil.fi/jako/kuvat/2017-05-26_19-34-48_DCKsGlUG.png kuolemaa kohti ":D"
12:07 PM Emil: https://emil.fi/jako/kuvat/2017-05-26_19-35-18_dYoNnivk.png
12:08 PM polprog: do i se a dc-dc somewhere there?
12:08 PM Emil: yes
12:08 PM polprog: so what's this one for?
12:08 PM Emil: "via-vituke" is a fucking perfect name for this one
12:09 PM Emil: polprog: eink
12:09 PM polprog: ah that eink
12:09 PM polprog: ive seen it on ebay, it's yuge
12:09 PM Emil: it s
12:09 PM polprog: meanwhile i added two pushbuttons for the eval board
12:09 PM polprog: waiting to be programmed in asm
12:09 PM Emil: haha :D
12:10 PM Emil: Implement the serial bootloader
12:10 PM polprog: i guess i should add decoupling,
12:10 PM Emil: and be done with it!
12:10 PM Emil: also yes
12:10 PM Emil: There are two things
12:10 PM polprog: i didnt think clearly yesterday evening
12:10 PM Emil: Aiiiiiiiiiiiiiiiiiiiiiiiina kaikki maat yhteen
12:10 PM Emil: And
12:10 PM Emil: "Sprinkle some kerkos there boiiii"
12:12 PM polprog: eee
12:12 PM polprog: i dont think i get it
12:12 PM polprog: https://puu.sh/w1Psx/597e41e3a2.png the schem btw
12:13 PM Emil: "Always connect all the grounds together"
12:14 PM Emil: and
12:14 PM Emil: Springle some CER-capacitors there, young man
12:14 PM polprog: sure
12:15 PM polprog: i guess i will learn finnish by the way in this channel
12:15 PM polprog: kek
12:17 PM Emil: polprog: that's the plan ;)
12:19 PM Emil: sitten voimme kaikki kiroilla ja perseillä suomeksi! Voimmekkin myäs käyttähän salailssemppaa keeltä!
12:59 PM Emil: polprog: ummm
01:00 PM Emil: polprog: who do you have a led without a current limiting resistor=?
01:20 PM Emil: Got some input elsewhere:
01:20 PM Emil: More vias, because why the fuck not ;)
01:20 PM Emil: https://emil.fi/jako/kuvat/2017-05-26_20-50-11_wvIZd8Qw.png
01:20 PM Emil: https://emil.fi/jako/kuvat/2017-05-26_20-50-33_BUxNfbFp.png
01:33 PM bss36504: It hurts me that your stitching vias are not on a grid or following a pattern :(
01:33 PM Emil: hahahah :D
01:33 PM Emil: ikr
01:33 PM Emil: I know I know
01:33 PM Emil: it triggers my ocd, too
01:33 PM bss36504: You just shit them out without any regard for aesthetics.
01:33 PM Emil: ikr :D
01:34 PM Emil: I like to spread the känser ;)
01:34 PM bss36504: lol
01:34 PM bss36504: Is there a switching regulator on there? I assume so from L1 and L2
01:34 PM Emil: yeah
01:35 PM Emil: It's the world's shittiest eink driver :D
01:35 PM bss36504: Oh gotcha. never hurts to via-fence those bad boys.
01:35 PM bss36504: Why the shittiest?
01:36 PM Emil: bss36504: because it uses m328pb
01:36 PM bss36504: Oh well there
01:36 PM bss36504: ...there's that
01:36 PM bss36504: fat fingered the enter key, sorry
01:36 PM Emil: you do know the screen is fucking 800x600x2 bits yuge :D
01:36 PM bss36504: Yeah you linked it yesterday
01:37 PM bss36504: It is tremendous
01:37 PM Emil: But for what I've it planned it's okay
01:37 PM Emil: it'll update perhaps once an hour
01:37 PM bss36504: Are you calculating the bitmap algorithmically, or storing it in the 328's memory?
01:37 PM Emil: "storing it"
01:37 PM Emil: ":D"
01:38 PM Emil: Nah
01:38 PM bss36504: What are you making, if you don't mind me asking?
01:38 PM Emil: I'll just take text input and display that
01:38 PM bss36504: Oh
01:38 PM Emil: bss36504: sikrit, but once it's done I'll show it
01:38 PM bss36504: fair enough
01:38 PM Emil: Hmm
01:38 PM bss36504: why the PB? Just for the novelty?
01:39 PM Emil: bss36504: 328pb is cheaper and better available
01:39 PM Emil: Strange, I know
01:39 PM Emil: Hmm
01:39 PM Emil: Now I shall order some pizza
01:41 PM polprog: Emil: good eye on that vcc led
01:41 PM polprog: the schem was made basing on the real board. there of course is a resistor there :P
01:42 PM bss36504: polprog: I'm sure you were just attempting to make the worlds simplest voltage regulator with integrated power indicator
01:42 PM polprog: this is exactly why i think that we should indeed post our schems so we will find what we overlooked
01:43 PM polprog: bss36504: if it goes poof on the prod board, then it was not necesary :^)
01:43 PM bss36504: Exactly, you're just weeding out the weak parts
01:44 PM bss36504: s/parts/components
01:49 PM bss36504: Hey, anyone have a recommendation on a N channel mosfet that comes in TO-9x and ideally also a TO-220? 2N7000, for example, comes in both, but the Rdson is waaaay too high at 5ohms. The TO-9x guy will be used for low-current power gating (<100mA) and the TO-220 is for heavier power switching, though I'm not too choosy on specs besides rdson
01:49 PM bss36504: Or maybe two different FETs, one in each package?
01:50 PM Emil: bss36504: :D
01:51 PM polprog: bss36504: P55NFxx, comes in to92,
01:51 PM Emil: bss36504: why do you need such crude packages?
01:51 PM Emil: bss36504: use surface mounts like a proper person
01:51 PM polprog: quite low RDS, <0.015ohm
01:51 PM bss36504: Emil: It's for a student-assembled daughter board
01:51 PM bss36504: They literally cannot do surface mount
01:51 PM Emil: bss36504: I'm a student
01:51 PM bss36504: (well 99% of them anyway)
01:52 PM Emil: all my designs are 99,9% surface mount
01:52 PM bss36504: Yeah, you're in the 1%
01:52 PM Emil: lol
01:52 PM Emil: if that's you teaching fucking shove the students to surface mount
01:52 PM polprog: i try to make all my designs (even rasterboard) in smd and im not even a student yet xD
01:52 PM Emil: if it is your design fucking move to surface mount
01:52 PM Emil: bitch
01:52 PM Emil: ;9
01:52 PM Emil: ;)
01:52 PM polprog: bss36504: http://www.st.com/content/ccc/resource/technical/document/datasheet/05/20/63/2d/c6/d4/40/b9/CD00002311.pdf/files/CD00002311.pdf/jcr:content/translations/en.CD00002311.pdf
01:52 PM Emil: bss36504: heheeh
01:53 PM bss36504: Emil: We like to have actual success. I shit you not one student came to me and asked why his board wasnt working; VDD and GND were clearly soldered together on a 0.1" header
01:53 PM Emil: bss36504: I'm so encouraged by being able to fix that memory card bga that I want to do all my designs on bga/qfn from now on
01:53 PM Emil: but the fucking parts are not available :D
01:53 PM Emil: fucking digikey
01:53 PM Emil: bss36504: :DDDDDDDD
01:53 PM polprog: >bga
01:53 PM polprog: do you need someone to talk with?
01:53 PM bss36504: QFN is fine, BGA is more trouble than it's worth for hobby stuff, IMO. If my reflow oven was complete and I had stencils, maybe, and I consider myself to be high functioning on the soldering ability spectrum
01:53 PM Emil: lemme upload a video
01:54 PM Emil: bss36504: lol wtf, fixing that bga stick was a fucking walk in the park :D
01:54 PM Emil: bss36504: but really
01:54 PM Emil: do your students a favour and push them to surface mount
01:54 PM polprog: ^^^
01:54 PM Emil: I'm running a course this summer and that's my fucking plan
01:54 PM polprog: this so much
01:54 PM bss36504: Emil: No, cant do it.
01:54 PM Emil: "Surface mount or you fucking fail the class"
01:55 PM Emil: ":D"
01:55 PM polprog: also smd on a resterboard doesnt look like shit, as THT does
01:55 PM polprog: you can always surface mount DIPs
01:55 PM polprog: ;)
01:55 PM bss36504: These are people who may have never picked up a soldering iron. They don't even understand the mechanics of a good solderjoint, much less have the dexterity to actually complete it
01:55 PM polprog: teach them then
01:55 PM Emil: yeah
01:55 PM Emil: they'll learn
01:55 PM bss36504: Now, there are some optional SMD components for the more advanced students.
01:56 PM Emil: bss36504: what university?
01:56 PM bss36504: No you dont understand, If i have 15 students in a lab for a semester, we CANNOT be debugging hardware the whole time
01:56 PM Emil: lol
01:56 PM Emil: bss36504: that's why they debug outside of class
01:56 PM bss36504: "University" :P Small state college in VT, USA
01:56 PM Emil: and if you use premade pcbs then debugging should be easy af
01:57 PM Emil: bss36504: I've never really understood the difference between colleges and unis
01:57 PM bss36504: Listen, if I had my way, it would be all TSSOPs and 1206 caps and resistors, as an intro. But the more senior profs have put out the directive to have this board be mostly through hole.
01:57 PM Emil: I suppose they might be like we have universities of applied sciences
01:57 PM bss36504: I think the whole College/Uni thing is a pretty fine line.
01:57 PM Emil: >tssop
01:57 PM Emil: >1206
01:57 PM Emil: >as intro
01:57 PM Emil: pls
01:57 PM Emil: 0603 or go home
01:58 PM Emil: well, 0805 is fine as intro
01:58 PM Emil: ;)
01:58 PM bss36504: Unis are usually bigger in the US, may have sub-colleges for specialization.
01:58 PM bss36504: Colleges tend to be smaller
01:58 PM polprog: my intro wa 1206, then i went on to 0603
01:58 PM Emil: polprog: nice jump
01:58 PM bss36504: Other than that, not quite sure what the distinction is
01:58 PM bss36504: Fuck em, lets do 0203
01:58 PM Emil: bss36504: lol
01:58 PM bss36504: 0205?
01:58 PM polprog: some of them wont see it
01:58 PM polprog: kek
01:58 PM Emil: bss36504: no one told you to go overboard
01:58 PM bss36504: whatever the fuck it is
01:59 PM bss36504: Ok ok, so its mostly through hole stuff, but there are some optional SMD components
01:59 PM bss36504: a SOIC current sensor, a DFN-14 triple axis magnetometer
01:59 PM Emil: polprog: you remember my first board?
01:59 PM Emil: polprog: the one I showed here?
01:59 PM bss36504: plus associated Rs and Cs
01:59 PM Emil: polprog: diy pcb and shit
01:59 PM polprog: Emil: no, you can post it again
01:59 PM Emil: polprog: I designed and fabricated that in 12 hours or so :D
01:59 PM Emil: without sleep
01:59 PM polprog: nice marathon
02:00 PM polprog: 12 hours from idea to thing
02:00 PM bss36504: Emil: If you have never had the experience of teaching a large group of people how to do something they have no understanding of, you can't empathize with my decision :P
02:00 PM Emil: had to be ready the next day
02:00 PM Emil: bss36504: I have!
02:00 PM Emil: bss36504: and I speak from experience!
02:00 PM bss36504: I stand corrected
02:00 PM polprog: Emil: i started an intro on finnish, i like the way the syntax is free like in polish
02:00 PM bss36504: Must be your students arent as dumb as mine lol
02:00 PM Emil: polprog: if you learn some Finnish I'll reward you with ebay gifts/beer/something
02:01 PM Emil: bss36504: they are dumb as fuck, mate :D
02:01 PM bss36504: lol, some yes
02:01 PM polprog: Emil: if you learn some polish, we could make a channel-wide travelling hacker box
02:01 PM Emil: polprog: uuh
02:01 PM Emil: I like the idea
02:01 PM bss36504: it's funny, it's like a reverse bell curve. I have really high achievers, and really low performers, not really anything in the middle
02:01 PM bss36504: incredibly frustrating
02:01 PM Emil: though I'm pretty Murican with learning other languages :D
02:02 PM Emil: bss36504: that I can symphatise with
02:02 PM Emil: bss36504: designed classes for that is brutal anal rape
02:02 PM Emil: or feels like that
02:02 PM polprog: bss36504: divide them in two groups. That's what was done in our school's english class
02:02 PM Emil: polprog: I wouldn't do that
02:02 PM Emil: the dumb don't learn and the smart just do their own shit
02:03 PM polprog: so what? freedom!
02:03 PM Emil: but also when you pair the dumb with the smart the smart get frustrated
02:03 PM Emil: polprog: but tell me about that channel wide travelling hacker box!
02:03 PM bss36504: No, what seems to work better is to provide extra credit on labs/homeworks etc. The dumb ones will scrape by, but the good ones will tend to learn more
02:04 PM Emil: bss36504: yeah
02:04 PM polprog: there are 4 levels of competence, the first is when you don't know you need a certain skill. You can't learn shit unless you realize you need skill X, which is level 2
02:05 PM polprog: Emil: a bunch of people signed up to a list and pass a box of electronic junk around them. https://hackaday.io/project/7373-travelling-hacker-box
02:05 PM bss36504: OTOH, we (as an institution) don't necessarily equip them for the type of critical thinking and problem solving skills that they may need in some of these situations, such as soldering. It's something I try to push, and to some extent im successful, but I'm just a young adjunct faculty member, so I have limited sway
02:05 PM Emil: ananas, kebab, ham (not the good one but the basic shit), pepperoni, onion
02:06 PM Emil: bss36504: yeah I recently taught a class about linux
02:06 PM polprog: ananas xD
02:06 PM polprog: it's pineapple in english :P
02:06 PM Emil: bss36504: and I said to them: "University is quite a lot about just learning to learn and being able to find information and applying it"
02:06 PM Emil: polprog: I know
02:06 PM Emil: polprog: you haven't noticed how I have a distaste for anglisms ;)
02:06 PM polprog: me too, sometimes
02:07 PM Emil: rate that pizza
02:07 PM bss36504: Emil: yeah, exactly. I try to give them slack on soldering, since you cant learn good technique from reading alone. And for the sake of our lab, through hole is adequate.
02:07 PM polprog: 6/10 pizza
02:07 PM xentrac: I don't think "ananas" is actually a word in English
02:07 PM Emil: polprog: wtf
02:07 PM Emil: polprog: you take that back
02:07 PM Emil: polprog: fuck you
02:07 PM * xentrac fucks polprog
02:07 PM Emil: 2017-05-26 21:37:32 +0300 -!- #avr You're not a channel operator
02:07 PM Emil: fuck
02:07 PM Emil: :D
02:08 PM * xentrac fucks Emil for good measure
02:08 PM Emil: xentrac: ah, babe, you like that yeah
02:08 PM Emil: give it to me harder
02:08 PM xentrac: mmm
02:08 PM bss36504: Emil: we also have a lot of "non-traditional" students, aka older folks who traditionally have poor eyesight, shaky hands etc. They would be physically incapable of soldering 0603, and that's even before we talk about the sad state of lab soldering stations
02:08 PM xentrac: I'm not sure about this "learning to learn" thing
02:08 PM Emil: bss36504: you don't have microscopes?
02:08 PM bss36504: xentrac: It's code for "Critical thinking"
02:09 PM bss36504: Emil: We have a few, yes
02:09 PM xentrac: I feel like a lot of university stuff incentivizes worst practices for learning
02:09 PM Emil: xentrac: you know, I used to fucking hate when people say that
02:09 PM xentrac: cramming, memorizing, that kind of thing
02:09 PM Emil: xentrac: but suddenly I have come to understand what it means
02:09 PM bss36504: brb, coffee break
02:09 PM xentrac: here I'm talking about classes, not research
02:09 PM polprog: Emil: btw how old are you? 20something?
02:10 PM xentrac: polprog: my girlfriend and I were looking at basic Finnish grammar last night
02:10 PM Emil: polprog: 21 :(
02:10 PM Emil: polprog: I have had one age cricis already
02:10 PM Emil: another is here about soon
02:10 PM polprog: xentrac: what's your native language? :P
02:10 PM xentrac: English
02:10 PM polprog: oh, poor guy
02:10 PM xentrac: she's studying Greek and is finding memorizing declensions annoying
02:11 PM Emil: xentrac: what encouraged you to look at Finnish?
02:11 PM polprog: french for you then :P
02:11 PM Emil: ah
02:11 PM xentrac: I was like, "You know, in Classical Greek, there were actually five cases and sometimes three numbers, which made it a lot more complicated"
02:11 PM xentrac: and then of course I was like "Listen, you really have to look at Finnish, where there are fifteen cases"
02:12 PM xentrac: we boggled at Finnish for a while before going to sleep
02:12 PM polprog: it is not like you have to memorize cases on the first try...
02:12 PM xentrac: also we listened to Greek pop music and read bits of Greek Wikipedia
02:12 PM polprog: im learning russian for a year now at school and i dont even know how many cases are there
02:13 PM Emil: polprog: Russian!
02:13 PM Emil: That's awesome :D
02:13 PM Emil: Always wanted to learn it
02:13 PM Emil: but I have no time/interested in learning it or any other language, really :D
02:13 PM xentrac: you already speek Polish and English, Emil?
02:13 PM polprog: maybe im biased because the book is in polish ofc and many things are intuitive for us, and they would not be for english or french...
02:13 PM Emil: xentrac: wat no
02:14 PM polprog: he doesnt speak polish, jeszcze
02:14 PM Emil: xentrac: Finnish and English
02:14 PM Emil: and some Swedish
02:14 PM xentrac: oh, sorry
02:14 PM xentrac: right, of course
02:14 PM Emil: but fuck mandatory Swedish
02:14 PM polprog: swedish is funny af
02:14 PM Emil: nej, det är inte
02:14 PM polprog: it's like english grammar with german dictionary loaded
02:14 PM polprog: or the other way round
02:15 PM xentrac: apparently there are six main cases in Russian and "several minor cases", polprog
02:15 PM Emil: svenska språket är jävlä dummar
02:15 PM Emil: or something like that
02:15 PM Emil: I probably made a fool out myself already
02:15 PM Emil: well
02:15 PM polprog: that would make sense since there are 7 cases in polish, the 7th one is rarely used
02:15 PM Emil: I'm just kidding
02:15 PM polprog: vocative
02:15 PM Emil: Swedish is fine and the language is nice
02:16 PM xentrac: yeah, both modern and classical Greek have a vocative that you almost never use too
02:16 PM Emil: I (like many Finns) just have hatred left over from the mandatory classes and it manifests as hatred for all Swedish
02:16 PM xentrac: heh
02:16 PM bss36504: I feel like a dummy for only knowing american
02:17 PM Emil: bss36504: learn Finnish
02:17 PM polprog: learn polish
02:17 PM Emil: I'll reward you with things from Finland
02:17 PM Emil: or ebay
02:17 PM bss36504: How hard is it, coming from english?
02:17 PM polprog: Ill reward you with things from poland
02:18 PM bss36504: Alright, it's settled, I'll learn Finlish
02:18 PM Emil: bss36504: it's quite hard
02:18 PM Emil: what states was vt?
02:19 PM xentrac: bss36504: http://www.atlasandboots.com/foreign-service-institute-language-difficulty/ says it's about twice as hard as Spanish or Swedish, but half as hard as Arabic, Japanese, Chinese, or Korean
02:19 PM bss36504: My real question is, how do you so easily add all the umlauts and accent marks (or whatever the f that circle thing is) in here?
02:19 PM polprog: compose key
02:19 PM bss36504: Emil: What about Vermont?
02:19 PM bss36504: aka VT
02:19 PM xentrac: I use https://github.com/kragen/xcompose
02:19 PM polprog: divine shit
02:19 PM * xentrac divines shit
02:19 PM Emil: bss36504: ah
02:20 PM Emil: bss36504: it was one of those small states
02:20 PM xentrac: itty
02:20 PM Emil: bss36504: anycase, you are close by to Michigan
02:20 PM polprog: Emil: look at that box project
02:20 PM Emil: bss36504: there's a place calld Finland and a "Finnish" university there iirc
02:20 PM bss36504: yeah, super tiny. But, we have the most breweries per capita of any state in the US
02:20 PM Emil: polprog: did you link it?
02:20 PM polprog: yes
02:20 PM Emil: polprog: ah yeah
02:20 PM polprog: you are not reading my messages
02:20 PM Emil: polprog: this conversation is too speedy :D
02:21 PM * polprog cries
02:21 PM bss36504: Emil: hahaha I can honestly say I've never hear michigan being characterized as "close to vermont"
02:21 PM Emil: I'm losing mysel to links and reading this :D
02:21 PM bss36504: heard*
02:21 PM Emil: bss36504: well, is it not!
02:21 PM Emil: bss36504: compared to like Cali or some shit like that
02:21 PM Emil: )
02:21 PM Emil: )
02:21 PM Emil: ;)
02:21 PM Emil: Fucking hell
02:21 PM bss36504: I mean, the whole US is about 3000 miles coast to coast, so michigan is about half
02:21 PM Emil: polprog: also, not eating anything doesn't fucking help :D
02:22 PM polprog: not eating anything, wat?
02:22 PM bss36504: Ok, sorry, not half
02:22 PM bss36504: I google mapped it
02:22 PM polprog: ah you are hungry ok
02:23 PM xentrac: like a third, no, bss36504?
02:23 PM bss36504: 1174km from Burlington VT where I live to lansing MI
02:23 PM bss36504: I even put the distance into units you guys would understand
02:23 PM bss36504: xentrac: yeah more like a third
02:23 PM bss36504: It would be almost 1000 miles if you didnt go into canada.
02:24 PM Emil: polprog: https://goo.gl/photos/qEthRpQoP8AEQ4pT9

02:24 PM polprog: o/
02:24 PM Emil: polprog: cya
02:24 PM bss36504: bye polprog
02:25 PM Emil: bss36504: but flights are cheap ;)
02:25 PM xentrac: what's 1174km from Espoo?
02:25 PM Emil: bss36504: take your girlfriend there
02:25 PM Emil: xentrac: to the hand of Finland
02:25 PM bss36504: Well Emil, if you ever make it to the east coast of the US, hit me up. I'll bring you to the best beers in the state
02:25 PM Emil: xentrac: all the way up north
02:25 PM Emil: bss36504: will probably happen at some point
02:26 PM Emil: I have relatives in Canada and a godmother in Maine
02:26 PM bss36504: Maine is a nice state
02:26 PM xentrac: are you Christian?
02:26 PM bss36504: who?
02:26 PM bss36504: me, no
02:26 PM xentrac: Emil:
02:26 PM Emil: xentrac: fuck
02:26 PM Emil: no
02:26 PM xentrac: haha
02:26 PM xentrac: but she is I guess?
02:26 PM Emil: well
02:26 PM Emil: dunno
02:26 PM Emil: probably tapakristitty
02:26 PM Emil: like most people
02:27 PM bss36504: Cool word
02:28 PM Emil: bss36504: Finnish is really flexible
02:28 PM Emil: bss36504: anycase
02:28 PM Emil: bss36504: you see that board?
02:28 PM Emil: I linked
02:29 PM bss36504: Yeah looks good
02:29 PM bss36504: What does that one do?
02:29 PM Emil: https://goo.gl/photos/stdjmXg92DKLPLzS9
02:29 PM Emil: Here's a video
02:29 PM Emil: about the board
02:30 PM Emil: bss36504: that's the first ever real diy pcb and project I made
02:30 PM Emil: bss36504: it's a control board for an rc car
02:31 PM Emil: it was for robot wars https://goo.gl/photos/CoK9LqJinmFXEtSS7
02:31 PM Emil: but I didn't have the time to program it :D
02:32 PM bss36504: I dig the background music :D
02:32 PM bss36504: Looks cool
02:33 PM bss36504: Home etched I assume?
02:35 PM polprog: night workshop shot
02:35 PM polprog: https://puu.sh/w1VWI/065b57d149.jpg
02:36 PM Emil: bss36504: yeah diy
02:36 PM Emil: bss36504: thanks :)
02:37 PM Emil: polprog: https://emil.fi/jako/kuvat/2017-05-26_22-06-45_P0dnYM7D.png
02:37 PM Emil: what's this?
02:37 PM polprog: music is the thing every workshop needs ;)
02:37 PM bss36504: I never got into the home etching
02:37 PM bss36504: OSHPark and before that, BatchPCB spoiled me
02:37 PM Emil: bss36504: home etching is super fucking useful
02:37 PM Emil: you can get down to 0.250mm tracks and clearance
02:37 PM Emil: but vias are a pain to make
02:37 PM bss36504: yeah, very true, but I like vias
02:37 PM polprog: Emil: A 5V 4A psu, with a polyfuse board ever since a shorted atmega melted the breadboard
02:38 PM Emil: lol
02:38 PM Emil: :D
02:38 PM polprog: i dont have a bench psu
02:38 PM Emil: Make one
02:38 PM polprog: sure, someday
02:38 PM Emil: I'm probably making my own soldering iron soon
02:38 PM polprog: nixe
02:38 PM Emil: the driver, that is
02:38 PM polprog: nice,
02:38 PM bss36504: why tho? lol
02:38 PM Emil: Don't want to pay for it since I'm poor
02:38 PM bss36504: just because?
02:38 PM bss36504: Oh fair enough
02:38 PM bss36504: I thought you were a gainfully employed professor :D
02:39 PM polprog: professor of applied iron making
02:39 PM polprog: xD
02:42 PM Emil: bss36504: hehe
02:43 PM Emil: bss36504: me, a professor?
02:43 PM Emil: I'll fucking frame that :D
02:47 PM bss36504: My students address me as professor in emails despite my very casual lecturing style and that I always sign my emails with my first name. It's a weird title to me, and the rest of the college is pretty lax on addressing the professors as "professor"
02:47 PM Emil: A professor at 21
02:47 PM Emil: damn that would be nice
02:47 PM bss36504: I'm 23 :P
02:47 PM Emil: bss36504: :D
02:48 PM Emil: bss36504: I like your college already
02:48 PM Emil: based on that
02:48 PM Emil: We Finns are also very lax with titles
02:48 PM bss36504: Yeah, it's more about the experience and the learning, not so much on formalities
02:48 PM Emil: Exactly
02:48 PM bss36504: As it should be.
02:48 PM Emil: Yeah
02:49 PM bss36504: Some uppity professors at more "distinguished" universities really should be careful not to break an arm jerking themselves off
02:49 PM Emil: hehe
02:49 PM Emil: I mean
02:49 PM Emil: If you are in official situations and shit like that
02:49 PM Emil: like if they ask your title
02:49 PM bss36504: I guess so
02:49 PM Emil: of course you are proud of it
02:50 PM Emil: but it's bad when you have to tell about it to others all the time
02:50 PM bss36504: but forcing a class of people, some of whom are older than me, to address me with a title that came with the job and not from my education seems really pretentious
02:50 PM Emil: I hold the opinion that once I've introduced myself, first name basis are exactly fine
02:50 PM Emil: yeah
02:50 PM bss36504: Indeed
02:50 PM Emil: that's silly
02:50 PM bss36504: Part of the problem with the higher education system in america is due to that pretentiousness.
02:51 PM Emil: yeah
02:51 PM xentrac: there was an editorial about this the other day
02:51 PM Emil: So I've hear
02:51 PM xentrac: in the NYT
02:51 PM Emil: d
02:51 PM Emil: hmm
02:51 PM Emil: can you link it?
02:51 PM bss36504: And why it's so expensive. All pomp and circumstance. I don't have the patience for it.
02:51 PM xentrac: I don't have the URL handy, no
02:52 PM xentrac: https://www.nytimes.com/2017/05/13/opinion/sunday/u-cant-talk-to-ur-professor-like-this.html
02:52 PM Emil: bss36504: Good to hear
02:52 PM Emil: bss36504: don't lose that
02:53 PM Emil: xentrac: Looking at just the title
02:53 PM Emil: xentrac: I already don't like that article
02:53 PM Emil: of course you shouldn't talk to people like that
02:53 PM specing: I concur
02:53 PM Emil: that's just fucking idiotic :D
02:53 PM specing: > u
02:53 PM specing: > ur
02:53 PM xentrac: haha
02:54 PM Emil: but that's not what it means to not be elitist
02:55 PM Emil: Hmm
02:55 PM Emil: What should I watch
02:55 PM xentrac: AvE
02:55 PM xentrac: or Homo Faciens
02:55 PM Emil: N oI mean
02:55 PM xentrac: or GreatScott!
02:56 PM Emil: Not something educational :D
02:56 PM Emil: I need to rest my brain
02:57 PM xentrac: clouds wafting by in the sky?
02:58 PM Emil: Hey War Machine came out
02:58 PM xentrac: AvE is pretty restful
02:58 PM Emil: I'll watch that
02:58 PM Emil: On NF
02:58 PM bss36504: xentrac: Interesting read. Some ok points on both sides. My opinion is that it's a bit pretentious to force the title on your students. I particularly liked one quote:
02:59 PM bss36504: “I always think it’s a power move,” she told me. “Just because someone gave you a piece of paper that says you’re smart doesn’t mean you can communicate those ideas to me. I reserve the right to judge if you’re a good professor.”
02:59 PM xentrac: yeah
02:59 PM xentrac: I think the piece is coming from ego
02:59 PM xentrac: but I also think there's an atom of truth in it
02:59 PM bss36504: I do have to concur with the desire to recieve well crafted and proofread emails though
03:00 PM bss36504: Just because we are casual does not mean we need to be unprofessional.
03:00 PM Emil: "I reserve the right" people are usually fucking annoying
03:00 PM Emil: :D
03:00 PM xentrac: indeed
03:00 PM xentrac: which is. well, I've several times been in the position of talking to super awesome knowledgeable people who could have taught me things, if only I had realized they were awesome
03:00 PM Emil: bss36504: but yeah
03:00 PM bss36504: I would prefer that my students have a report with me like I have with my manager at work. There's respect and boundaries, but we can also just chat like normal humans
03:00 PM Emil: 2017-05-26 22:29:54 +0300 < bss36504> Just because we are casual does not mean we need to be unprofessional < this exactly
03:00 PM xentrac: I think it's hard to teach something to someone if they think they already know it
03:01 PM xentrac: rapport?
03:01 PM bss36504: ah yeah, that
03:01 PM Emil: report probabvly
03:01 PM bss36504: lol
03:01 PM bss36504: sorry
03:01 PM xentrac: no wukkers
03:01 PM Emil: Hey this film looks pretty nice
03:01 PM Emil: I'll watch it
03:01 PM Emil: sorry have to tune out for two hours
03:01 PM Emil: Don't talk too much :D
03:01 PM Emil: I hate being left out :D
03:01 PM bss36504: I should probably do some work for the job I get paid to do lol
03:02 PM Emil: oh yeah and that too :D
03:02 PM bss36504: Only so many times I can handle running an LVS job in a single day
03:02 PM bss36504: Makes me want to stab my eyeballs out with one of my rubiks cubes. Yeah just try and figure out the mechanics of that one!
03:05 PM bss36504: If you're looking for a good AvE video, I very much enjoyed the Juicero teardown
03:05 PM bss36504: The comment about "Hope you're all wearing your fitbits" really got me
03:06 PM xentrac: the Juicero teardown was pretty fun
04:09 PM polprog: how exactly should i tell the c compiler to include an asm file?
04:10 PM xentrac: use the linker, not the compiler
04:10 PM polprog: i tried to #include "file.asm" but it tries to compile it as c
04:10 PM polprog: i just want to change my make file from gcc *.c *.s .. to gcc main.c
04:12 PM xentrac: yeah, you can't do that
04:12 PM xentrac: because it tries to compile it as C :)
04:12 PM xentrac: and it isn't C
04:12 PM xentrac: you could use inline assembly in C, or you could use the linker, as in gcc *.c *.s
04:13 PM polprog: thanks
04:48 PM Emil: Yeah you should definitely watch the War Machine
04:48 PM Emil: It is good
05:00 PM Lambda_Aurigae: bss36504, why would you want your students to have a report with you?
05:00 PM Lambda_Aurigae: maybe a rapport?
05:01 PM Lambda_Aurigae: oh, nevermind...someone else saw it first.
05:01 PM Lambda_Aurigae: I should keep scrolling.
05:13 PM FL4SHK: I've got a friend (yes it's actually a friend, not talking about myself) who wants to know, why is loading from flash slow?
05:14 PM FL4SHK: but executing instructions doesn't appear to be
05:16 PM Chillum: it is serialized going in from flash
05:17 PM FL4SHK: oh
05:17 PM FL4SHK: so one bit at a time?
05:17 PM Chillum: ohh, I was confused about which channel I was in
05:17 PM FL4SHK: oh
05:17 PM Chillum: I am thinking of the ESP8266 which has an external serial flash
05:17 PM FL4SHK: that happens
05:17 PM Chillum: I don't know how the internal flash avrs handle things
05:18 PM Chillum: thought it may well be
05:19 PM Chillum: I know avrs boast "While one instruction is being executed, the next instruction is pre-fetched from the program memory. This concept enables instructions to be executed
05:19 PM Chillum: in every clock cycle."
05:19 PM FL4SHK: oh that's a miniature pipeline
05:20 PM Chillum: it could explain why it takes longer to load data and do something with it
05:20 PM Chillum: than just executing it
05:20 PM FL4SHK: I see
05:25 PM Lambda_Aurigae: prezaktly.
05:25 PM Lambda_Aurigae: reading data from flash requires reading the data and writing it somewhere.
05:26 PM Lambda_Aurigae: where executing program does not require that data be rewritten somewhere and it is prefetched one instruction ahead of time.
05:26 PM Lambda_Aurigae: this is part of why some instructions like jump and branches and stuff take extra cycles too....dirty readahead cache.
05:38 PM Emil: wait
05:38 PM Emil: rapport is an actual word
05:38 PM Emil: wtf
05:38 PM Lambda_Aurigae: yes.
05:38 PM Emil: well
05:38 PM Lambda_Aurigae: pronounced rap-por
05:38 PM Emil: learned something new
05:38 PM Lambda_Aurigae: silent T
05:38 PM Lambda_Aurigae: or, rather, rap-or
05:38 PM Lambda_Aurigae: it's a french word as I recall.
07:02 PM Santh: That’s it :)
07:02 PM Santh: Rapport means report
07:03 PM Santh: (or « link » in some sentences)
07:04 PM Lambda_Aurigae: link or agreement in communication...something like that.
07:04 PM Santh: Yep, that’s the idea
07:05 PM Santh: /ACK :D
07:05 PM Lambda_Aurigae: NACK
08:42 PM Monster: hey
