~ 31 minutes ~

04:19

BingoBoingo: yeah, no need to ping, I ~always follow one way or another what I asked for and with a deadline at that.

~ 56 minutes ~

05:15

lol, scaaaary!

~ 7 hours 42 minutes ~

12:57

whaack: http://logs.ossasepia.com/log/ossasepia/2020-02-22#1019245 - the not being listed in /dev resolved itself then?

12:57

Logged on 2020-02-22 23:18:16 whaack: jfw: I selected /dev/sdb in parted and used the command print. I got the error 'Error: /dev/sdb: unrecognised disk label

12:57

Logged on 2020-02-21 22:43:53 whaack: B: I used a command, mkfs.ext4, on my hdd before fully understanding the command. Now my hdd is not listed in /dev/ and I don't know why. WTI: I don't know what to say. Obviously, don't use commands before understanding what they do.

13:00

whaack: the buffer I/O errors in the kernel log are something to look into. Could mean failing drive, loose connection or something. It does bother me how unspecific they are, unless there's some meaning hidden that I just can't decode yet.

~ 22 minutes ~

13:23

whaack: I don't have specific reading to recommend on circuits, but brushing up on the basics of electricity & magnetism wouldn't hurt; from that article I get the idea your HS physics teacher slept through his own lectures too (whether or not words were coming out of his mouth) and

13:23

would assume Ohm's Law got lost somewhere alongside f=ma

13:32

whaack: on the practice side, maybe get some breadboard and parts to play with, build some beginner projects based on schematics

~ 18 minutes ~

13:51

jfw: yes the /dev/ has resolved itself... I'm not quite sure how/why. As root, sometimes ls shows about 15 entries in that folder, sometimes it shows 190+

14:01

lol, 15, really? I suspect incorrect usage of measuring stick

14:04

now, udev is a thing, which adds and removes nodes based on hotplug events from the kernel, so it's indeed possible the sdb came and went based on those I/O errors / driver resets.

14:06

whaack: beware of problems that "resolve themselves" , lolz

14:06

jfw: Sigh, I have to come admitting more stupidity. I was judging the content of the folder half of the time based off of what i saw from hitting tab twice, not from using ls. ls always gives ~190 entries.

14:07

BingoBoingo: is that comment clear to you?

14:08

most files are not executables nor directories so..they're missing from the display of tab auto complete. I had the mistaken idea that sdb1 should be a folder.

14:08

sdb1 is a folder/directory*

14:09

whaack: ahh so not even tab complete in file context, which should be ~same as ls, +- dotfiles, but in command context, right.

14:10

diana_coman: It seems so with respect to measuring times. With respect to grouping the tasks, I have a suspicion something in the line of: Things I'm already comfortable with versus things I need to learn may be a useful grouping

14:10

http://logs.ossasepia.com/log/ossasepia/2020-02-24#1019312 - not that I'm against whaack's need to brush up on basic physics and all that but how did it come to circuits, what did I miss?

14:10

Logged on 2020-02-24 14:39:07 jfw: whaack: I don't have specific reading to recommend on circuits, but brushing up on the basics of electricity & magnetism wouldn't hurt; from that article I get the idea your HS physics teacher slept through his own lectures too (whether or not words were coming out of his mouth) and

14:10

BingoBoingo: no, grouping is by topic, not by your comfort level, lolz

14:10

diana_coman: Alright

14:10

if you want to add the comfort level for your own measurement, add it, sure

14:10

diana_coman: http://logs.ossasepia.com/log/ossasepia/2020-02-23#1019266 re circuits

14:10

Logged on 2020-02-23 19:09:33 whaack: infamous for. A recommendation on a textbook or source to learn about circuits would be greatly appreciated.

14:11

but you can't do a meaningful grouping by a thing that is anyway first of all your characteristic rather than of those things you aim to group and second anyway poorly defined & not exactly measurable as such either.

14:12

jfw: ah, I see; anyways, forrest mims on electronics probably but before that ...basic physics indeed.

14:12

whaack: ^

14:14

thank you for the clarification

14:14

BingoBoingo: the point of the grouping is to see which directions you are covering and to what extent; ideally you'll also notice from the exercises directions that are missing/not covered - but this would work better indeed if you had already even a draft plan re wut-do-with-qntra since that's the focus anyway

14:16

http://logs.ossasepia.com/log/ossasepia/2020-02-24#1019314 not a bad idea. I have some potential kits in mind -> http://ossasepia.com/2019/08/12/camera-tests-of-a-sunday/

14:16

Logged on 2020-02-24 14:48:21 jfw: whaack: on the practice side, maybe get some breadboard and parts to play with, build some beginner projects based on schematics

14:16

jfw: is it fair to say that your planning/daily schedule actually works quite fine for you (except when/if you have in there some of the eeek-factor tasks)?

14:18

whaack: lol, if it serves, then why not!

14:19

diana_coman: it's been working pretty well, if not 100%

14:20

diana_coman: I'll push to get that draft out tomorrow or wednesday. Right now, the mid and long term are where I am seeing the least clarity

14:21

jfw: eh, next you'll carefully observe that efficiency in practice is *also* (annoyingly! inadmissibly!) not 100%!

14:22

BingoBoingo: hopefully you do realise that there's a different level of detail that is required and makes sense for each level there, right?

14:22

diana_coman: efficiency is never 100% even in theory, heh

14:22

aka by "clarity" you are not looking to see concrete detailed steps for the mid and long term

14:23

jfw: ha, you admit plainly to it!! heh.

14:25

diana_coman: The realization that this isn't a gathering of fortune tellers did occur to me, but the fineness and broadness out on each level is... not something I've had much practice weilding.

14:27

BingoBoingo: the more reason to get out a draft faster rather than slower since there's not much to gain by ...waiting; it's through iteration you can get better at it, not through staring at it for longer; anyways, the main idea there is to take your aim and then look to identify as many directions towards it, pretty much; do understand that it's not some "promise" ie don't block anything too early, there's plenty of time to ...

14:27

... prune/change any plans.

14:31

diana_coman: Alright, I'll aim to minimizing the staring before publication when I pick it back up again this evening.

14:32

sounds good; can anyway stare at it to your heart's content *after* publishing,lol.

14:33

jfw: talking of publishing and staring - any eta for your next article?

14:40

diana_coman: 22:00 UTC.

14:41

nice.

14:46

diana_coman: I've grouped the items by which hat I'm wearing and flagged, for myself, the items including more of that scary unfamiliarity.

14:49

BingoBoingo: you missed 9, lol

14:50

Ah, ty. Can't let that important personal management task fall on the floor.

14:51

BingoBoingo: and huh, is 4 (reviewing contributors' submissions) scary too?

14:53

diana_coman: It doesn't strike me as scary, but reviewing his homework as part of the course is a newer, less familiar thing. So I decided to bias towards flagging it.

14:53

I guess you can directly tell there now just by the number of tasks in each group how the whole is skewed.

14:53

The skew is a lot more visible after the grouping.

14:54

anyways, it's fine for this week for starters, but yeah, need to see it and consider it as it shouldn't keep going /get worse.

15:02

Thank you.

jfw beholds his impressive powers of non-starting and chickens out of today's ETA.

16:38

I'll scrape some corrosion from my battery terminals and retry for 19:00 UTC tomorrow.

~ 5 hours 44 minutes ~
