that's a good one. i'm gonna add it to my bashrc. thanks user.

I forgot to say, I also do my finanaces in Octave

man history [see Event Designators]

Thanks man, but im getting stuck on step one, since i have problems with basic math (think advanced high school), and it is stopping me from pursuing a career related to computers, since most (good) universities here have math, that I would inevitably fail.

reading a lot and investing a lot of time is step one. find a book that is at your skill level, and invest that time into it.

I need to learn calculus in 2 months in order to pass first year. I know how to calculate derivatives or simple limits, more abstract questions is what is mostly struggle with, and everything that has trygonometric functions

thoughts on this book? I'm an EE major and I'm considering buying it (my university doesn't use it, though)

I don't mean to scare you. Honestly though, calculus in 2 months is nothing compared to 3rd and 4th year material, maybe on par with year 2. If learning a lot of material in a short time sounds daunting, then stay away from STEM.

Bad for learning material for the first time, great for refreshing yourself on what you already mostly understand.

I used Calculus by Larson, Hostetler, and Edwards 7th ed years ago back when I was in highschool. Got me through the AP exam. It has a lot of practice problems.

Does void really do this? Even Debian stopped splitting its package management between binaries.

Not alias, but put this in your .bash_profile and thank me later.

How do you actually bloat a pic up to a specific size like 666K using the terminal?

I'm afraid to do so.
What does your script do? I don't understand.

Chroots are not jails.

Fuck you're right. I set that up forever ago and haven't really thought about it since.

Look into sudoedit. Benefit is that it makes a copy and only touches the real file when saving.

alias sudo="sudo "

Sorry but how is that different? Like the file doesn't get affected until I save anyway.

I have that one too. Good alias.

Just do a lot of exercises (of which you have the solutions, otherwise you won't know if you actually solved them) and when you don't know how to proceed read the theory and find a solution. If you really can't then use Wolfram Alpha, but only to look at the specific passage you can't solve, you'll remember it next time.
I passed my calculus exam this way studying all day starting 5 days before the exam, but how much time you need depends on what you learned in high school, I'm also not from America

Are you guys even trying? Quantitize your PNGs! Beats JPEG on drawn content.

i think it daemonizes like, 90% as well as doing it in c. i'm pretty sure there are ways you could still get a tty with this but it depends on the program being run (sleep 60 in this example). it's a quick mess i just made today so you'll have to forgive the redundancy and other minors ugly points.

set this script as your login shell for 1337 security
#!/bin/bash

ip=$(hostname -i)
latency="$(ping -c 1 $ip | grep -o 'time=.* ' | cut -d= -f 2 | cut -d. -f 1)"

Try control+L

Install xtools, you dingus

this is funny because it deletes the whole os! :D

cdls() { cd "$@" && ls; }

perform an ls when you cd, this is my most oft used alias

df -h | grep | awk '{ print $4 }'

just prints the amount of free space in human-readable units on my backup drive

Bullshit. Compare the png in with yours. There's a visible difference and you introduced artifacts in the right half of the image as well. It's just not as obvious as with the other ones.
This is perhaps not the smallest possible version, but the smallest lossless version optimized at a reasonable speed.
