Q: Do we accept grawlixes anywhere on the site?

In a comment, a user used the &%@# symbols to "hide" the swear word: wont that F@£% up my Laptop – t01vO 15 mins ago My reply was: No, why would it? Also, please try to use appropriate language - mess up would be fine? Especially this instance, where it was obvious what the word was, I dis...

Even Django has spam problems on their website.

9:33 PM

@LuisAlvarado ty

@NathanOsman wow... you want to look at these people and say "REALLY?"

Which people?

the people that post things like sleep apnea spam on django websites and their ilk. it's not even marginally related.

They're not brilliant.

They're probably not even human.

What worries me is that some people are actually falling for this. Otherwise there wouldn't be a market for it.

Read something the other day about code execution vulnerabilities in poison-ivy clients. Made me giggle a little... okay lot. Loads of people probably got double and triple owned after that article dropped

9:51 PM

writing a bot in ruby. This should be pure fun

i think of ruby as more of an art form than a coding language - and python more of a programming language that can be artful... but that's just me.

@Lucio: you know what language I've been learning that is absolutely 100% pure awesome?

Go.

Seriously, the more I learn, the more awesome it becomes.

Go looks awesome as does Vala, but they can't compete with the existing number of libraries for more established languages.

I remember your first 2 days

No, but Go offers probably the best approach to parallel computing I've ever seen in a programming language.

9:55 PM

"WTF" every line

@hbdgaf I was thinking the same yesterday

It's not a good language for writing a GUI application. But for a high-performance server app? It's perfect.

Python is awesome, but it is very difficult to properly do event-driven programming in Python. And then there's the GIL.

@NathanOsman how is it hard to do event driven programming in python?

Say you write a webserver. Each request must either be handled (1) serially, one-at-a-time (2) by utilizing events/callbacks (like Twisted does).

The moment one of the requests calls *.read() or something else that blocks, none of your other requests can be serviced.

CUPS experts, assemble!

Thread queues and careful management of context for anything you reach towards from a thread.

9:59 PM

Python doesn't do true multithreading. Only a single thread can be running Python code at any given time

@hbdgaf or, you know, use C :P

@NathanOsman sure it does, but the core python guys often recommend an extra process instead of a thread

Q: Unsynonimyze cups and printing

I can print without CUPS and I can ask a CUPS question without asking about printing. They are closely related tags but separated enough to be on their own. There are several CUPS related tags in the site, so why CUPS itself doesn't have its own? Log files (CUPS) grow so fast! <--- CUPS adminis...

A: Python, Ruby, Haskell - Do they provide true multithreading?

1) Do Python, Ruby, or Haskell support true multithreading? This has nothing to do with the language. It is a question of the hardware (if the machine only has 1 CPU, it is simply physically impossible to execute two instructions at the same time), the Operating System (again, if the OS does...

the answer is: depends the implementation

Well, then how is setting up and using IPC easier than just using Go? :)

10:01 PM

That's a fair point. People have their pets I suppose. I know I do.

@Braiam Everyone uses CPython :P

@hbdgaf Don't get me wrong. Python is still 100% awesome. It's just not the perfect language for everything.

This is also true. I just don't see anything else with as many libraries, harnesses to other languages, etc.

@NathanOsman no language is perfect... look, God had to use Perl

@hbdgaf Except C. There is nothing in existence that doesn't have a C-compatible library :P

@NathanOsman nuf said

10:03 PM

:)

True. Revision - Hard to screw up really horribly by accident languages.

C is great for one thing - embedded programming.

cough assembly cough

I've been there too, but C is a bit higher-level. And still lets you do almost the same things (although there's no C command to switch CPU modes or something silly like that).

C Everyone's favorite macro assembler

10:06 PM

damn, I created a '-R' file that breaks any command >.<

~~You can create a file with "/" in the name.~~

~~Try deleting that one.~~ Never mind, I was thinking of something else.

using sudo and -f

of course!

now seriously people, how the heck may I remove this file O.o

well, when you absolutely positively must remove a file from the os, you edit a file table pointed to by the partition table then run a zfill utility to clear it out :)

only the TAR command works. This is extremely sad

@hbdgaf oh right. Doing that thing that I learned on the University. Silly of my memory!

Can't you just quote it?

rm "-R"

Otherwise try:

rm \-R

Other than that, I have no idea.

10:11 PM

I tried anything

none

You might have to do it the hard way.

can you edit it?

@Lucio ls?

I'm going to create a file like that and see if I can remove it.

if you can open it, you might be able to get an inode number from /proc somewhere and kill it with fire

10:13 PM

You're right - it is hard to remove.

@Braiam it is a valid argument! I can't!!

➜ transmission-2.84 git:(master) ✗ touch -- '-R'
➜ transmission-2.84 git:(master) ✗ rm -- -R

git directory, ignore everything else

^worked

wuffff what a relief

that one silly thing was hard

Who wrote the TAR command? I want to kill him/her/it...!

Ah stupid me. There's a really simple way.

rm ./-R

And that actually works.

10:16 PM

that seems like the strangest video I could ever seen in my life

yep, it was

@Lucio is a cool video

"How many Ubuntians do you need to remove a file?"

i could have dropped a link to mindhunters circa 2004. that would have been stranger. i was just saying - just relax a little. i'm half way through my weekend goals so far. so i'm "don't worry, be happy"

today I had a really cool day so far

i'm game - how so?

10:27 PM

ehh, what?

I don't know what are you trying to say

how was your day cool?

oh

3 people with broken computers == $

all in 4 hours, so it wasn't a pain

only a big amount of coffee

@Lucio "I'm game" means "I'm ready", "I'm willing", "I'm good with that", similar to "I'm cool".

now I have time for write my scripts and the day is not finishing

@Seth thanks

weird phrase for me

np :)

10:34 PM

@Braiam any new soundcloud hit to listen?

if you're needing a new song to jam out to... you could try this youtube.com/watch?v=5t5QSiydF9Y

thanks - you should add '&html5=1' to every shared YT link

Today's Listening | Electronic / Psychedelic / Glitch Hop / Dubstep

thanks

Look guys, you can answer 2 years old questions and still get feedback, old questions needs love!

awsome

11:11 PM

hi guys

does anyone know how do I resize a Linux partition?

@Jovito did you tried just, you know, looking around?

gparted works pretty well for that.

@Braiam

I did

it seems I need to boot some kind of program to get it done

the one I actually have installed won't let me do it

If it's your root partition, you will need to do it from a LiveCD (or USB).

@Jovito and?

11:19 PM

the option 'resize/move' is greyed out

well

Is it the root partition?

@Jovito are you trying to resize a mounted partition?

If not, you might be able to unmount it.

I have no way to boot right know

my flash drive is broken

it is the root partition

yes it's mounted

@Nathan is there no other way to do it?

No, you can't resize a mounted partition.

And you can't unmount the root partition easily.

Do you have a CD burner that you could create a LiveCD with?

11:23 PM

Yeah but no cds...

not right now.

I'm afraid there really isn't much you can do then. :(

@Nathan Could the partition be resized through another OS, like Windows?

Possibly - if you use a third-party tool.

@Jovito I wouldn't touch a linux partition with any windows tool

3

Windows' disk manager is not able to resize ext2/3/4 partitions.

11:27 PM

@Braiam why?

~~This might be of assistance: ubuntuforums.org/showthread.php?t=1564519~~ Never mind.

Yeah hahaha

It basically said what you just told me.

Power outage.
