I think there's a prize, but I don't think anyone from where I was were really competing for it. @jrg This was written in CSS3... incredibly clever game. archive.globalgamejam.org/2012/wrrrm

@Flabricorn Cute graphics

@Mochan Not me, our artist was amazing. abitfrank.com

jrg

@Flabricorn whoa

that's slick

Flabricorn

@jrg Everyone on our team was amazing.

Mochan

@Flabricorn Very nice. I envy her(?)

Flabricorn

@Mochan Her, yes, but all the games we saw were pretty swell, the majority was Windows or Mac, I don't think there was one Linux in the airport.

Mochan

@Flabricorn Wah :( She's an excellent artist

Flabricorn

9:01 PM

@Mochan Which is why I'm learning Pixel Art, because I think her art skills bypass "The Sheeps" (Our team name from 2012) game making skills. In which case she will probably not be on our team this year.

Mochan

@Flabricorn Awesome. Good luck.

Flabricorn

@Mochan Thank you.

Man is it ever quiet today.

Flabricorn

@GeorgeEdison Quiet as the vacuum of space.

George Edison

In other news... I have written (yet another) web server in Qt. You can see it here: home.quickmediasolutions.com:8000

Mochan

9:09 PM

@GeorgeEdison Congrats :)

George Edison

:P

Hang on, I'll be back in about 30 seconds - I need to plug in another monitor...

Mochan

I'm going now, see you all :)

Flabricorn

@Mochan Goodbye!

jrg

is there anything like the .app format for linux?

George Edison

Briefly... what is the .app format?

jrg

9:17 PM

the .app format is a spec that apple has

that is basically a folder that ends in .app

has two folders inside it

one something like bin, the other something like share (as in /usr/local/share)

George Edison

Python has something like that called a "binary distribution".

It's basically an archive containing the package's contents as they would be organized in an actual filesystem.

AbrahamVanHelpsing

hulu added a nice new button i really like "watch latest free episode" <-- good idea

/OT

jrg

@GeorgeEdison anything that is language independent?

George Edison

Some companies just distribute binary installers.

jrg

AND HOW DO THEY CREATE THEM!?

George Edison

9:27 PM

They probably create them themselves :)

jrg

I know that - HOW?!

George Edison

They write an application :)

jrg

because i want to do something similar for a proprietary app i'm developing.

George Edison

If there is sufficient interest, I might be convinced to start such a project.

Qt for example offers a flexible resource management system that allows applications to embed files and data in the application.

jrg

fpm - fing package management.

George Edison

9:29 PM

(I think at one point, NSIS was being ported to Linux.)

jrg

let me chart out the tree i want things to look like

AbrahamVanHelpsing

base64 or uuencode their components in a shell script and extract them from a bash script...then rename it to .run. seems to be the modus operandi

jrg

(and now i'm just rubber duck debugging)

@AbrahamVanHelpsing .run is a evil, evil EVIL EVIL EVIL FORMAT.

AbrahamVanHelpsing

yes. i know. but you asked how they did their own installers

George Edison

Stick with ELF files.

In fact, this would be perfect for Qt.

jrg

9:30 PM

i spent 1 week (12/hr days) debugging a .run file.

Flabricorn

@jrg Sometimes I wonder, if .run is such a terrible format, WHY does it still exist?

jrg

@Flabricorn no clue.

Flabricorn

@jrg .bin isn't the greatest either.

jrg

before i gave up and marked the bug "wontfix"

George Edison

You've inspired me to write something...

Now I just need a name for it...

AbrahamVanHelpsing

python has a module where you can have an in-memory filesystem and add that to sys.path. works fine for everything that doesn't have binary extensions

George Edison

9:45 PM

Whoa... 2buntu.com is malfunctioning.

Kyle Macey

Anyone elseo notice the Download for Ubuntu images are broken?

I just went through and added it to a bunch of answers as per the style guide

A: How to post links that integrate with the Software Center?

Volunteers Wanted! Here is a search of posts with "sudo apt-get install" but are missing apps.ubuntu.com links (we filter out "error" and "ppa"). If you want to make a difference for new users, add these buttons to existing questions where appropriate! https://www.google.com/sear...

George Edison

It's loading for me.

Kyle Macey

Hm. Maybe cached

I can't get hostmar.co to resolve

George Edison

Kyle Macey

which is where it's hosted

George Edison

9:51 PM

Hmm... it's not loading for me now.

Let me run a traceroute...

Kyle Macey

Can it be hosted on askubuntu? Do mods get that sort of option?

George Edison

They could make a request for that.

Kyle Macey

Here, I uploaded one to one of my own posts i.stack.imgur.com/bXigo.png

so it's hosted through SX

-ish

can't find the smaller one

At least the SX imgur account

@KyleMacey I've reviewed some of your edits. They're good edits, but your summaries don't really help. When you say "Improved Question", we already assume that an edit improves the question. The edits themselves are good.

You can say things like "changes quote to code, punctuation".

Kyle Macey

Yeah I had for a while

Then I had seen "improved question" on other people's edits

I thought that was the universal

ObsessiveSSOℲ

10:00 PM

Those users who do that should be warned in chat if they are around.

Kyle Macey

Ok, I'll be more diligent

ObsessiveSSOℲ

Thanks! They're good edits. I don't deny that.

Kyle Macey

Thanks. Sorry for slacking a bit.

ObsessiveSSOℲ

No problem. Usually it's not a problem but when reviewers glance over suggested edits quickly, it helps to have a good summary.

Kyle Macey

Understood.

10:04 PM

Anyone know how sudo actually elevates users? The sudo executable itself is run as a regular user. Is it some sort of backend daemon that does these things?

George Edison

@ObsessiveSSOℲ It's simply a wrapper for the sudo Linux syscall.

ObsessiveSSOℲ

Ah. How is this syscall limited to only the sudo executable?

George Edison

Limited to sudo?

Actually hang on, let me check something...

ObsessiveSSOℲ

So I can;t make a little executable that elevates freely. It's sudo(executable) that parses sudoers.

George Edison

This answer might help explain things:

A: How to works sudo? To build it in Go

So you want to re-implement sudo in Go. This is weird. I suggest to study the source code of sudo at first. You need to understand carefully how Unix works at the system level. Did you read a book like Advanced Unix Programming and/or Advanced Linux Programming? Do you understand well the role o...
