Brother! So I'm not the only one who pulls a "grep -A9999"?!?!
(No joke, I have it a script which I use to combine exam questions into a single Canvas question bank.)
R. L. Dane :debian: :openbsd:
Hah! It's a great help.
I used to do a while loop and use a variable to define whether or not to print the line, but grep -A9999 (or -B9999) is so much easier and faster!

Ah. I really need to read up on sed. :)
$ man sed
...
The full documentation for sed is maintained as a Texinfo manual. If the info and sed pro‐
grams are properly installed at your site, the command
info sed
should give you access to the complete manual.
EAT ROCKS, GNU!!! ARGH!!!!!

If I wanted to read manuals in emacs, I'd run man in emacs!
@living8bit
FWIW, I often do! ?
R. L. Dane :debian: :openbsd:
...except for the GNU tools, which have crap manpages because they have to strongarm you into using stupid info. :/
Keep pushing me to BSD, GNU. Keep pushing me. :P
R. L. Dane :debian: :openbsd:
I've taken to using DDG and !freebsdman when I want to look up a manpage when GNU doen't feel like providing decent manpages.
Except I do it from the commandline, using a script I wrote called `duck` which detects which text-based web browser you have and turns the parameters into a DDG url. It also converts periods to bangs, so you don't have to quote or escape the bangs from the commandline.
So it looks like:
$ duck .freebsdman sed
R. L. Dane :debian: :openbsd:
Do you like info, then?
@living8bit
Honestly I don't use it enough to have an opinion. I tried but much of the "info" I need has been found in 'man'.
@living8bit
What? A text-based browser? ?
During one lecture I used one to demo what could be done "on the command line". In Zoom chat I see, "What!? That's so cool!"
Had to pause, mute my mic, and laugh.
R. L. Dane :debian: :openbsd:
Nice.
I love the fact that you can watch youtube on the commandline, even in the fbdev.

So you're saying that English is mispronounced mispronounced Latin.
Benjamin Hollon
@RL_Dane @gordoooo_z @sotolf
You keep making me want to learn Esperanto.
The more and more I study French, the more I realize how much of English is just mispronounced French.
Benjamin Hollon
@gordoooo_z @sotolf @RL_Dane
The other way to get that result is to live in a *highly* multicultural environment like Penang, Malaysia, where they end up standardizing on a language like English just so that people can communicate with each other.
R. L. Dane :debian: :openbsd:
@benjaminhollon @gordoooo_z @sotolf
Also, that sounds a lot like the place where L. L. Zamenhof lived, which inspired him to create #Esperanto
(To be clear, he lived in Europe (I forget exactly where), but it was a very mulicultural city with some cultural friction, partially because of the lack of a shared language)
Yer ol' Pal Gordo
@sotolf @RL_Dane @benjaminhollon ...would probably be handy, but then again, I've met hundreds of people from India and Pakistan, and maybe like... 1 or 2 that didn't speak English?
Monocultures are boring but having a language that's damn near universal sure is convenient.
Yer ol' Pal Gordo
@sotolf @RL_Dane @benjaminhollon I find Italians pretty easy to get along with on account of they seem to enjoy feeding me large servings of carbs and cheese ? well that and I'm Italian on both sides, but I'm definitely more Canadian than anything, lol.
They liked to tell us in school that French would be useful one day, but I can probably count the number of francophones I've spoken to for more than a few words on my fingers. Hindu or urdu...
Sotolf
Hah, it's a possibility, I never got along well with Italians for some reason :p
My white whale for the last years has been to learn a slavic language, probably slovenian as it's the one spoken the most around where I live, but the motivation is kind of hard to get.
I know the most useful languages around me otherwise, and some a bit more esoteric like Danish, Swedish and japanese, but most of the time it's German and English, they are useful.
Yer ol' Pal Gordo
@sotolf @RL_Dane @benjaminhollon I've read some very interesting research on the subject, actually.
I wish I didn't lose the bit of Italian I'm told I knew as a child. I don't even understand it now, let alone speak it.
Weirdly though, I find it easier to parse Spanish than Italian. Similar syntax, but less syllables I guess, lol.
Sotolf
@gordoooo_z @RL_Dane @benjaminhollon
My brain is luckily still pretty plastic, probably because I've spent so much time learning languages, it's a blessing and a curse, but it does come in handy some times :)
I was very happy for it when I moved to a country where nobody spoke the languages I knew well :p
Yer ol' Pal Gordo
@sotolf @RL_Dane @benjaminhollon I believe it! Never underestimate a child's ability to absorb information. Little sponges.
Thank God I like to learn, because it only gets harder with time ?
Sotolf
I remember the time that I couldn't help the small one with his German homework anymore, it went from me helping him to him just telling me "Papa, das ist falsch..."
Yer ol' Pal Gordo
@sotolf @RL_Dane @benjaminhollon Yeah, I'm the same way. My girlfriend's sister decided it was time for a career change, and just finished her first semester of engineering school. The first month or so, she was coming to me for homework help. I had to warn her to enjoy it while it lasts, because she probably wasn't going to get more than a couple weeks more before she knew more than me.
I was not wrong lol

R. L. Dane :debian: :openbsd:
I guess what I'm saying is,
Time can be a burden. You don't really become you until around 13 years or so. Really 16. Before that, memories are very unreliable, because your self-definition is in flux.
A couple decades after that (36), you start to feel a little old.
A decade after that, your awareness of having many, many years stored up in the ol' hippocampus starts getting a bit heavier.
...
R. L. Dane :debian: :openbsd:

Once you start rounding the bend to half a century, man, you try not to reminisce too much. At least, I don't. It feels weird to be able to think back 30 years and have perfect recall. It's a strange kind of burden.
But also, I'm blessed/cursed? with crazy good long-term memory. Name any year, and I'll tell you all about it, down to season-level accuracy.

GAFAM reminds me of "GORFRAM," which was an onomonopia for getting hit in the head with a frying pan in a comic book I read as a kid, which was actually a 70' textbook relating to Education.
Man, the older you get, the more weird memories you pick up. It was called "Captain Con Man" -- CONtingency MANagement. It was the only thing in my stepdad's office that looked remotely interesting, so I flipped through it several times while waiting for him there.

Ah, I relate. I remember when I had... *sigh* a rather hasty and upsetting interstate move ten years ago*, I had to get rid of a lot of stuff I loved (including my sweet Classic Mac), and I was in the live-out-of-my-backpack mentality for a couple years after that.
*No, I didn't do anything illegal or immoral. I just wanted to get out of a situation, and needed a fresh break.
Benjamin Hollon
@RL_Dane @gordoooo_z
Yeah… I've had a couple unexpected inter-country moves, so… I don't know that the feeling'll ever go away. And I'm planning to move away from the US after uni, so that'll be another move (though not unexpected).
> *No, I didn't do anything illegal
Now I feel the inexplicable urge to write a story about you on the run from the law. Would that qualify as fanfiction, I wonder?
Benjamin Hollon
@gordoooo_z @RL_Dane
Yeah, it can be frustrating, but for me I *need* something portable for… let's say, "psychological reasons." Is that sufficiently vague? ;)
R. L. Dane :debian: :openbsd:
Not hard to guess. There's a lot of freedom using a laptop.
When I got my first one in 1995, it felt AMAZING to be able to compute anywhere. It was a dinky little dell 486 (pretty old even at the time). It had a trackball on the screen bezel ( :eyeroll: ) and a murky grayscale STN LCD.
Loved that little thing for two years until I got my epic Latitude XPi CD MMX 166.
What a chonktastic beast!
Benjamin Hollon
Well, not just that. Potentially due to being brought up with the implicit expectation that we'd be moving countries every few years, I feel extremely uncomfortable if at any point I can't pack the things I need in two suitcases and get on a plane to move.
So yeah… laptops are *much* more in line with that than a desktop.
Yer ol' Pal Gordo

If you're interested in education reform I'd very much recommend the blog of a former English teacher of mine: https://jmhieber.wordpress.com/
He's pretty much singlehandedly propelling my High School toward going gradeless and focusing on feedback-based learning.
- I went into my first class with him "hating" writing and came out wanting it as a career
- He introduced me to Linux
- He has a Framework Laptop (previously an old thinkpad)
- He's a TCK!
R. L. Dane :debian: :openbsd:
My stepdad was big on education reform. He taught Cirriculum & Instruction at UT Austin for decades.
He got about as far as you'd expect.
People don't like reformers. People don't like change, and don't like to have to care about things.
Benjamin Hollon
@RL_Dane @living8bit
(can I just say that even though I'm *good* at standardized tests I hate them and think they're a very poor system that needs drastic reform—I know someone, for example, who is a very smart person [smarter than me in some ways] but had a below-average score on the SAT)
Benjamin Hollon
@RL_Dane @living8bit
To become a National Merit semifinalist, you need to score in the top 0.5% of your state on the PSAT. To reach it as a semifinalist, you need to score in the top 0.5% of the *highest scoring state*. Plus, because of COVID, a bunch of people that year were allowed to submit SAT scores that year instead of PSAT ones, but SAT has a *higher maximum score* so the highest-scoring state had the highest qualifying score in history.
Thank God I somehow hit the mark.
Benjamin Hollon
You pretty much *need* a scholarship these days.
Baylor's scholarship offer was higher in monetary value than A&M but I still would have been paying something like $30k per year. They sent out a survey asking why I didn't choose to go there, and I boilied it down to: "Given the comparitave offers from Baylor and A&M, it would have been an incredibly stupid financial decision to attend Baylor."
Benjamin Hollon
@RL_Dane @living8bit
I mean, I have a National Merit scholarship and Baylor apparently does *nothing* for that. Back in my parents' day, they gave full ride for that.
And getting National Merit as an international student is nigh impossible; I was the only student in Malaysia to reach semifinalist status, and I know I'm the first at my school to get to Finalist (one other has reached semifinalist).
R. L. Dane :debian: :openbsd:
Nice!! Good work!
Never had a scholarship, but I did get on the deans list, so ;)
@living8bit
Yeah, I didn't do dorm life either. After visiting a dorm, I'm glad I didn't. At the Uni the hallways smelled of urine. ?
Benjamin Hollon
@living8bit @RL_Dane
Not my experience, luckily. These dorms are nice and very well-maintained.
Also expensive, but everything is in the US and I've got two nice scholarships and in-state tuition so I can afford to swallow it. :P
R. L. Dane :debian: :openbsd:
Nice!!!
Benjamin Hollon
@RL_Dane @living8bit
Yeah! Best part to me is I get to stay in the same dorm, which is normally only for Honors Freshmen. It's a great location and some of the largest rooms on campus. ;)
R. L. Dane :debian: :openbsd:
Ah, I missed out on dorm life, although it may be that I didn't miss much.
I *did* live in a dorm for a week or two in computer camp (yes that was a thing in the 80s) when I was 9. That was pretty cool -- high-rise dorm in the heart of Austin (Dobie Mall/Center).
Benjamin Hollon
@living8bit @RL_Dane
Ha, I'm a student not a teacher, but that does sound awesome. ;)
I will be an instructor for a class next semester but I don't do any of the grading work or have any say in the curriculum so I probably don't have that status on Canvas.
@living8bit
Lucky you! I started teaching to share ideas with students and learn things from students. After remote teaching, it's been more paper and police work. :(
Benjamin Hollon
@living8bit @RL_Dane
Well in my case I'll be a Sophomore Advisor for the University Honors program here, so nothing fancy, but I do get to help some smart fish through their first year. And it sounds like we might get paid a bit, if they feel like it.

@living8bit
Since we're on the subject, if anyone is interested in a script which converts an Emacs OrgMode-formatted file of questions into an QTI.zip file importable to Canvas, let me know.

Benjamin Hollon
@RL_Dane @living8bit
Hmm I'll explain better. Basically, there are two outside cultures you're exposed to as a TCK: your "home" culture and your "host" culture. In many cases like my own, there are multiple host cultures, but it's the same idea.
...
Benjamin Hollon
@RL_Dane @living8bit
...
As a TCK, I belong to neither of those cultures; TCKs have their own "third" culture that they only share with each other. While TCKs often have a hard time building relationships with what I've heard jokingly termed "monoculturals," we can become BFFs with another TCK in ten seconds flat. Even me, and I'm a strong introvert.
R. L. Dane :debian: :openbsd:
Ahhh. Wait, what are the first two? ;)
Benjamin Hollon
I like dorm life, but that's maybe just the me who doesn't drive and likes being able to roll out of bed and be showered, dressed, and at class within 30 minutes. Also it might be nicer in a dorm where all residents are Honors students than in one with more rowdy residents. ;)
R. L. Dane :debian: :openbsd:
I remember when apm (the predecessor to ACPI) was disabled in the linux kernel whenever SMP (Symmetric MultiProcessing) was enabled... because if you had more than one CPU, why the heck would you be worried about energy usage? ;)
R. L. Dane :debian: :openbsd:
They can be, but it's measuring very different things. CPU utilization is just a part of system load. A high system load due to CPU 'pressure' (the term htop uses) alone would be like having 500% CPU utilization -- too much for the CPUs to take care of even at full tilt.
Benjamin Hollon
@RL_Dane
Ah, I miss the days when Windows Task Manager would give me a nice simple graph of my CPU usage from 1 to 100. I was so naive then.
Benjamin Hollon
@RL_Dane
Hmm, interesting, I think for me in the past they've been relatively correlated.
R. L. Dane :debian: :openbsd:
...
But generally, load and CPU usage aren't strongly linked. I've seen insane loads with next to no CPU usage (too much i/o at once),and I've seen pegged CPU usage with moderate load (CPU 100% utilized, but not overstressed so much that things in the kernel start falling behind).
Benjamin Hollon
@RL_Dane
I feel like if you're trying to communicate load, this works better?
~] uptime
21:04:14 up 3:44, 0 users, load average: 0.14, 0.18, 0.17
I mean, I guess you have to understand what the load averages mean.
R. L. Dane :debian: :openbsd:
No, load is just kernel "pressure" in general -- how long the various "queues" (buffers?) within the kernel are. It can be from lots of i/o, lots of movement in memory, lots of processes being created, or possibly high CPU usage.
