@Zacharee1 How come you're always sleepy in the afternoon?

Don't you get enough sleep during the night???µ

@Fabby on average I get 7 hours of sleep a night. However, I also have insomnia. Add that to the headaches, huge amount of homework, misophonia, and the walking around a large campus to different classes, and you get fatigue of no other kind

Fabby

Go see your physician: you should get 10h of sleep at your age!

Zacharee1

@Fabby oh, and anxiety

I could get something like 8, but I feel like something would go wrong if I slept to 7

Fabby

@Zacharee1 GO ... SEE ... A ... DOCTOR!

(I'm not a doctor, but I can see someone needing one!)

Teens should be able to sleep 10h/day.

You need it to grow!

Zacharee1

@Fabby For which? I've seen one for the headaches, no one knows why. Misophonia: no real treatment. Walking can't be avoided. Anxiety -- I don't know

Fabby

12:11 AM

@Zacharee1 Start with a Psychiatrist...

My dad used to have really bad migraines and he went to see one because our GP told him to and he delayed it for years "because he wasn't crazy" and the first thing the Psychiatrist told him was: I'm a brain doctor, not a brain surgeon!

He hasn't had any migraines for the last 30 years or so...

Zacharee1

er

user139252

I sleep about 6 hours a night

user139252

@Zacharee1 migraines or headaches?

Zacharee1

@TheBrownOne dunno

frequent though

Fabby

@Zacharee1 Go see a Psychiatrist and tell him that an old fart in a chat room told you to go see a psychiatrist because of his even older dad and his migraines and that Psychiatrists aren't just there for crazy people but they know more than any other doctor about brain chemistry!

Zacharee1

12:23 AM

hmm

That'll probably have to happen over the summer or something :/

Fabby

Why not on Saturday?

Why not tomorrow?

Good luck in that school! You're going to need it!!!

I am confused by this line in a book: "operating system passes all of your shell's environment variables to programs that the shell runs, whereas shell variables are not accessible by the commands that you run."

12:38 AM

Okay I have ./speedtest-cli-extra

can I use crontab to make it run every 30 mins?

Zacharee1

@daBoss something like: stackoverflow.com/questions/25740573/…

?

Abhishek Bhatia

@Fabby Anenvironment variable is like a shell variable, but is not specific to the shell. All programs on Unix
systems have environment variable storage. The difference that you will notice is that the operating
system passes all of your shell's environment variables to programs that the shell runs, whereas shell
variables are not accessible by the commands that you run. Some programs use environment variables for
configuration and options. For example, you can put your favorite less command-line options in the LESS

Zacharee1

@daBoss or: stackoverflow.com/questions/11260406/crontab-every-5-minutes

Fabby

@AbhishekBhatia reading...

@AbhishekBhatia OK, so an environment variable would be something like $PATH and a shell variable would be anything set in a shell config...

so a shell variable in a bash shell would only be readable by the bash shell and a ksh variable would only be readable by the ksh, whereas an environment variable would be readable by both... (cc @Seth)

Makes more sense now? @AbhishekBhatia

@Fabby thanks, that certainly makes it more clear! Where can I find these shell variables specific to a shell? Environment variables I think are in etc/environment

yeah, the BL is the easy part.

Finding a ROM that will run from 4.4.2 seems like it will be trickier.

Zacharee1

CyanogenMod

Seth

1:36 AM

Apparently the VZW version has a qfuse that blows if the device upgrades past 4.2.2 that causes issues.

@Zacharee1 CyanogenMod specifically will not work.

@Seth forum.xda-developers.com/galaxy-s3-verizon/development/… !!!

Seth

@Zacharee1 yeah I was looking at the one earlier

what makes you think it will actually work?

Zacharee1

@Seth It's for the Verizon GS3, so I'm just guessing. Also, it looks like you only soft-brick your phone if something goes wrong, so you can always flash back to stock if it doesn't work

Seth

2:03 AM

@Zacharee1 the BL wasn't locked until 4.3 so anyone before that could have flashed a custom bl/recovery/whatever, hence the reason a few ROMs do exist.

Zacharee1

@Seth hmm. I figured that maybe it'd also work for 4.4

Serg

So. . . .i got myself qemu this morning... now how do i do stuffs ?how do i install stuffs ?

Nathan Osman

qemu... wow, that's pretty intense.

I'd recommend starting with an amd64 virtual machine and once you are comfortable, moving to a foreign architecture, like ARM.

da Boss

lol I couldn't figure out what was eating all the space on my 32gb microsd card on my pi2

I never ran raspi-config and expanded the filesystem...

Serg

Sure, I'll try to get amd64 of 16.04 first

Nathan Osman

Lol.

da Boss

3:31 AM

it was 96% full...

now it is 4%

Nathan Osman

@Serg keep in mind that qemu does both KVM and full system emulation.

The former is similar to VirtualBox. The other will be about 20-40x slower.

(Okay, maybe not quite that much, but it will be much slower.)

da Boss

I still don't know what to do with my second pi...

Nathan Osman

Buy a relay and use it to control an appliance.

da Boss

I could put some sort of sensor on it so i could get a text message when my coffee is done...

or the coffee...

I want to be able to flood your kitchen on demand!

da Boss

@NathanOsman my wife likes tea...

Nathan Osman

Then it can return the "418 I'm a teapot" HTTP status code.

Yes, there's actually an RFC for that.

"Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0)"

> "Coffee pots heat water using electronic mechanisms, so there is no fire. Thus, no firewalls are necessary, and firewall control policy is irrelevant. However, POST may be a trademark for coffee, and so the BREW method has been added. The BREW method may be used with other HTTP-based protocols (e.g., the Hyper Text Brewery Control Protocol)."

Lots of good humor in there.
