That reminds me of what happens every single time I type apt-get upgrade

Alex A.

wtf

FlagAsSpam

Don't forget about lobstertwo!

Dennis

More importantly, what do lobsters have to do with symbolic math?

Alex A.

Because one lobster is never enough

Doorknob

10:01 PM

Why does it need texlive for... anything? O_o

Alex A.

That explains why people call SymPy slow: it has a billion random dependencies.

Dennis

I have no idea.

Doorknob

@AlexA. why would that make it slow

Dennis

1. It wouldn't. 2. This is Ubuntu's fault, not SymPy's.

Alex A.

When you load it it probably gets ready you give you hella TeX lobsters

Doorknob

10:02 PM

tries to parse that sentence, fails

FlagAsSpam

Code Lobster? Reminds me of a B52s song.

Alex A.

@FlagAsSpam I'm glad someone made that reference. :P

Have you heard the Botch cover?

Dennis

# apt-get install python3-pip
# pip3 install sympy

FlagAsSpam

Nope.

Dennis

Problem solved.

FlagAsSpam

10:03 PM

You nailed it. :D

Dennis

With the new additions, I could do pyramid primes in 11 bytes. :/

FlagAsSpam

I have to use brew. :c

Written in Ruby.

So scary.

Alex A.

@FlagAsSpam OS X ftw tho

FlagAsSpam

But shiny. c:

Alex A.

@FlagAsSpam Why Ruby == scary?

FlagAsSpam

Fear of the unknown?

Alex A.

Homebrew is pretty legit

It destroyed my /usr/local/bin. xD

Alex A.

Uh in what way?

FlagAsSpam

I put all of my codes there. It removed some of them that have similar names.

Alex A.

Like the code you write?

Doorknob

10:07 PM

Make a ~/bin

Alex A.

FlagAsSpam

Eh.

Alex A.

It should be putting everything in something like /usr/local/bin/Cellar with symlinks or whatever in /usr/local/bin.

@Doorknob ?

Doorknob

@AlexA. faster :wq<cr> :P

Alex A.

Everything I type times out ;__;

Dennis

The -p in mkdir -p bin is not very golfy.

Doorknob

10:13 PM

Alternatively, map it to something sane in your .vimrc. Like <Leader>w, which is what I do.

Alex A.

@Doorknob I'll think about doing that after I figure out how to use vim like a real adult.

Doorknob

It is

FlagAsSpam

Because I use > as my prompt. And that's not what's in that profile. :P

The others are backups made by programs that modify your Bash profile

Doorknob

Alex A.

@FlagAsSpam Why do you need to sudo find? o_O

FlagAsSpam

Otherwise find will throw hundreds of "Permission denied"s. :D

Doorknob

Why are you doing cd ./; find . instead of find /?

FlagAsSpam

10:25 PM

Felt like it.

Alex A.

Also what is ./private?

I don't have that

FlagAsSpam

Uh.

It is indeed a lie

Oh, I have a /private but not a ./private. I assumed . was ~.

FlagAsSpam

No.

Alex A.

10:27 PM

Don't worry about those, just worry about the .bash_profile and .bashrc in ~.

@Doorknob Apparently ChromiumOS is somehow "better" at that. ¯\_(ツ)_/¯

Alex A.

@FlagAsSpam I find OS X to be the perfect multipurpose OS. It's incredibly stable and well supported, it's UNIX-based, the way it installs and handles programs makes sense, it's great for development, and there's a ton of great software for it.

Dennis

And you only need hardware that costs twice its actual value to run it.

Alex A.

@Doorknob s/programmers/skrub l0rds/

@Dennis Exactly

Doorknob

@AlexA. Every single one of those arguments applies to almost every single Linux distro too

FlagAsSpam

@Dennis This is my point.

@orlp Having a productive day, I see. :P

@AlexA. I find Windows XP to be the worst multipurpose OS. It's incredibly unstable and not supported anywhere, it's not UNIX-based, the way it installs and handles programs doesn't make sense, it's horrible for development, and there's no decent software for it.

I have enough hidden files in my home directory to have to scroll down to see anything in a just-opened Finder window.

Alex A.

@Doorknob I guess it works out well for me then that I do like the OS X window manager.

FlagAsSpam

This is not okay.

Dennis

@Sp3000 Oh, a built-in for the Gamma function? ! is already the Pi function, so I though Gamma could be used as ’!.

Doorknob

@FlagAsSpam hidden files are called hidden for a reason

Alex A.

@FlagAsSpam rm -rf ~/.* and see what happens

FlagAsSpam

10:36 PM

@Doorknob Eh. I need to see them 90% of the time.

@AlexA. No.

Sp3000

@Dennis Does ! work for non-ints? Not sure how you've implemented it

Doorknob

@FlagAsSpam Then pass -a to ls

def pi(integer):

That would break everything, I think.

Er... what were you using sympy for then?

@Sp3000 The built-in ÆP uses sympy.primetest.isprime. I've also implemented built-ins for sympy.ntheory.generate.primepi, sympy.ntheory.generate.prime, sympy.ntheory.generate.nextprime, sympy.ntheory.generate.prevprime and sympy.ntheory.generate.primerange.

@JamesLu It doesn't have a goal, which doesn't make it a great challenge. If my program is `` (nothing), then that would output nothing in a lot of languages.

I'm using LaTeX for a project. The project requires 12pt Times New Roman font. It pained me to use \documentclass[12pt]{article} and \usepackage{times}. ;_;
