when you're out of memory on a drive qbittorrent goes crazy and enters an infinite try/write loop

which results in an infinite number of error notifs showing

@AlexM. LeGrande Schematic

A story of a french student who robs a jewelry store for money but accidentally discovers the owner's secret plans to unveil revolutionary technology and AI which would change the ways of modern combat as we know it.

I wonder why gimp sucks so hard at resizing pics

this site causes less aliasing: picresize.com

Hello devs.

hasherr

Awesome video on A*

►

Alex M.

@hasherr a couple (or maybe just one?) profs or something enhanced the A* algo, google it

there were lots of stars about it months ago

can't remember the name

hasherr

How did they enhance it?

Alex M.

by making it faster, obivously

hasherr

Faster? It's already pretty fast, isn't it?

Alex M.

12:44 AM

dunno, I guess

for my needs any pathfinding algorithm is pretty fast

here, harablog.wordpress.com/2011/09/07/jump-point-search

jump point search

hasherr

I have no idea how to implement this

Alex M.

I am not asking you to implement it

hasherr

lol

Alex M.

I am asking you to be aware of it

hasherr

I'm asking myself to.

Alex M.

12:47 AM

Google teaches you how to do something, but it won't tell you about that something before it

Christian Careaga

@hasherr Thats the vid I learned from

Alex M.

so while you can't really memorize a ton of algorithms and possibilities, it is a good idea to keep their names in your memory, and a bit of info about what they achieve

so when the need arises, you can google them

hasherr

True.

@ChristianCareaga Yeah. I don't know how I'm going to implement this with a grid system.

Alex M.

this is technically what books do and the internet doesn't: they show you how to do things you didn't know existed

Christian Careaga

@hasherr it shouldnt be too hard!

hasherr

12:49 AM

Fuuuu

Christian Careaga

I just wrote the Game of Life with pygame!

pretty trivial actually

hasherr

Cool

Christian Careaga

Its pretty too!

Alex M.

do those pixels go to university in the game of life?

Christian Careaga

Yes they get married and have a family

Alex M.

12:55 AM

nice

this reminds me of a really awesome and underrated city building and life sim, called Cultures

if getting two people to marry, then getting them to have a kid, then getting him to grow up, to turn him into a soldier and send him to battle is your thing, then you should check out the game

the game also looks beautiful, despite its age

you can find the series on gog.com

Christian Careaga

That looks pretty cool!

Alex M.

yes, it's the 2nd game in the series but the first looks similar

except for the GUI

Lasse

Looks like it uses settlers 3 or 4 engine

Alex M.

gog.com/game/cultures_12 (cultures 1+2 for $9)

hasherr

That looks like it's aged well.

Ooh, rated Teen. I don't know. Not sure if I'm allowed to play

Alex M.

12:59 AM

I played it very long ago but if I remember this right...

babies are brought by storks

hasherr

Haha

Alex M.

and the sex is actually a heart showing above the partners' cottage

hasherr

I kind of want to play FTL right now, but A* is calling my name.

Alex M.

@Lasse might be

Christian Careaga

A* do it

Alex M.

1:00 AM

you can zoom in and out in the game

hasherr

@ChristianCareaga I don't know haaaooo

Alex M.

it looks 3d-ish

Christian Careaga

@hasherr wat are you having trouble with! the idea of it or implementing it

hasherr

Getting a grid set up. Not sure what I'm even gonna do for that.

Alex M.

also on gog there's Rune for $3.99 gog.com/game/rune_classic

they call it the Dark Souls of the past

never played it

Lasse

1:04 AM

settlers 3 had funny DRM

when you brought iron ore to the smelter, and it processed it, out became a dead pig

that pretty much made it unplayable after couple of missions

I don't believe it was ever cracked

tbodt

1:25 AM

anyone know about c++?

I have a question

Lasse

just ask, don't ask to ask

tbodt

ok

how do you make a class from which no other class can derive?

Lasse

make it final

tbodt

this is C++, not java

there's no final keyword

Lasse

oh, I thought there was as it is so common

parashift.com/c++-faq/final-classes.html

I googled that and found it in 10 seconds

you should try googling too

C++11 has the final keyword

tbodt

1:31 AM

hold on, I did something idiotic and have to clean up

ok done cleaning up

Alex M.

1:50 AM

final class Fantasy

Or something like that

hasherr

Okay, fuck this. I have no idea how to make a grid system in this LWJGL.

user4704

int grid[width * height]; //PROFIT

hasherr

No.

Almo

where's my GDSE pro LoL team? :)

Alex M.

2:07 AM

Byte came with a nice idea over at the gd.se game jam chat. By chance, would you like to work on a collective (multiple teams? Hackathon?) project together with people from graphics SE? Just an idea for the next jam (spring).

hasherr

        width = 1024;
        height = 1024;

        int xInterval = width / 32;
        int yInterval = height / 32;

        for (int i=0; i<=32; i++)
        {
            for (int j=0; j<=32; j++)
            {
                if (i == 1 && j == 1)
                {
                    Node node = new Node(0, 0, NodeType.START);
                }
                else
                {
                    Node node = new Node(i + 1, j + 1, NodeType.WALL);

                }
            }
        }

Fuu why won't this work

I'm probably too tired to be doing this now anyways

John McDonald

yeah, sleepy programming isn't productive

hasherr

Why the hell isn't that working...

user4704

Define "not working?"

hasherr

It only displays starting nodes

So it is continuing to loop through
if (i == 1 && j == 1)
                {
                    Node node = new Node(0, 0, NodeType.START);
                }

Instead of moving up to the next Node

user4704

2:14 AM

If you put a breakpoint on that line, do you actually see it hit there more than once?

hasherr

No, it only does it once

user4704

So what does that tell you?

hasherr

sigh

Dammit.

tbodt

what?

user4704

I presume the problem was elsewhere?

Lasse

2:23 AM

hasherr

No, what's happening is the numbers are too big and the thing is getting drawn over for some reason

tbodt

@Lasse what the heck?

hasherr

I don't know what it's doing.

        width = 512;
        height = 512;

        boolean startHasBeenPlaced = false;

        for (int i=0; i<=width/64; i++)
        {
            for (int j=0; j<=height/64; j++)
            {
                if (!startHasBeenPlaced)
                {
                    Node node = new Node(i, j, NodeType.START);
                    startHasBeenPlaced = true;
                }
                else
                {
                    System.out.println("LOOOOOLL");
                    Node node = new Node(i, j, NodeType.TARGET);

Lasse

I have a bezier curve, but I want to make it thick like that. Is that most easily accomplished that I go thru all lines of the curve and use a line in 90 degree angle to the curve to get the outer points?

Matt D

depends on how much you want to tesselate it

hasherr

2:24 AM

image sizes are 64/64, width and height of the screen is 512

@JoshPetrie So that should create 8 rows and 8 columns

Lasse

I want it to be as smooth as possible

Matt D

you could be a cheat, and just have a point every N along each "edge" spline, then make a triangle strip out of the points

so basically your wide brush is 3 splines, the inner, the outer, and the actual brush spline. the inner and outer are kind of parallel to the brush spline but offset

im sure there's lots of literature on "filling" solids

as this is what you're actually doing

hasherr

x: 0.0 y: 1.0
x: 0.0 y: 2.0

x: 3.0 y: 6.0
x: 3.0 y: 7.0
x: 3.0 y: 8.0

That is actually correct^

So this whole thing is working, they just aren't drawing correctly.

And I have no clue why.

Lasse

That's what I meant

Matt D

yes and thats exactly what i meant too

Lasse

2:28 AM

We're on the same page then

Matt D

you start with your guide spline, or brush. now do two more splines offset from that one (which is a fun process on its own)

then, you have an "inside" spline, and an "outside" spline

Lasse

yeah

Matt D

then you just tesselate using the inside and outside

im pretty sure there's lots of literature on how to fill solids. and this is essentially that case. you're just filling a curved solid

smarter people than I will have nice tricks to make it better/faster

Lasse

I'm not sure yet if it needs to be fast, as I am just precalculating the points and they remain static during the game

hasherr

3:11 AM

@JoshPetrie Hey, thanks for the push earlier. It's guys like you who make me want to keep going.

Also, I got my issue resolved.

Christian Careaga

@hasherr hows it going!

hasherr

It's going.

Christian Careaga

good!

hasherr

So I've got everything drawn

Christian Careaga

Is it working?

hasherr

3:21 AM

Lol, no. I haven't implemented the actual algorithm yet

But I understand it

And I don't think it will be hard

This is really just a test for a much much much more complicated, in-depth project that I'll be working on with a group of people most likely.

Christian Careaga

haha I made a little a* demo but it wasn't that good it was a bit buggy

the only problem was it could only go in one path, so if 2 neighbor nodes had the same heuristic it wouldn't split and go through both it would just pick the first one :/

hasherr

I see

So if it picked the first one, but the second one had the better path altogether, you were boned?

I added some shading to make it look prettier.

Christian Careaga

@hasherr exactly, but otherwise it worked, too lazy to fix it

Ohhhh pretty!

hasherr

That wouldn't have been hard to fix either.

Christian Careaga

yeah basically just had to call the getpath method but with a differnt starting point ahaa

Aidan Mueller

3:32 AM

@hasherr Did you ever fix that background? Or did you just say "screw this" and abandon the background all together?

Christian Careaga

but it was too learn a* and i think i was pretty successful in that so its okay

hasherr

@AidanMueller The background?

When?

Aidan Mueller

You were having issues with opengl

hasherr

@ChristianCareaga And yeah, that counts as a success. My biggest problem is that when I actually do this I'll have 2 maps

Aidan Mueller

Trying to get a background to load properly

hasherr

3:35 AM

And I'll have to tie together them

Aidan Mueller

Or maybe that was someone else :P

hasherr

@AidanMueller Yes, Mick and Lasse helped fix it. I'm currently putting that project on hold as I had something greater come up.

Christian Careaga

@hasherr I believe in you!

Aidan Mueller

That's how all projects get abandoned.

You say "I'll put this on hold". And you end up abandoning it forever

Christian Careaga

I have abandoned many projects

but what I always say "I used it as a learning tool, so I would say it was a success!"

Aidan Mueller

3:37 AM

If you want a learning tool, use ludum dare.

Lasse

monodevelop leaks memory, already using up 3GB

Aidan Mueller

What's mono develop again? It sounds familiar

Lasse

MonoDevelop is cross-platform ide for .net and mono projects

I'm using the latest build from github

Aidan Mueller

@Lasse Do you you use Linux, or do you just have a thing for penguins.

Lasse

both, they are so adorable

Aidan Mueller

3:40 AM

I am ~~thinking of~~ on my way to converting to Linux

Lasse

cool

I got fed up with windows more than a year ago, and I have had no regrets

Aidan Mueller

What was the first thing

?

hasherr

@AidanMueller I've put this project on hold before, and I've come back to it. I have every intention of finishing it. But a project came up that I fortunately have the oppurtunity to work on, and this project could get me a job if I did a swell job.

Lasse

thing?

hasherr

So my priorities have shifted but not faded

Aidan Mueller

3:41 AM

-that got you fed up

@hasherr I see

Lasse

don't get me started

hasherr

I made a promise to this room that I would finish this game, and I will.

Just not today.

Or tomorrow.

Aidan Mueller

Was it micro$ofts policies?

Lasse

I hate how the system always ends up as a mess on windows, linux package managers at least keep the system clean

Aidan Mueller

Yes

Lasse

3:43 AM

also, I love the linux way of installing software

Aidan Mueller

What I don't understand though is why people who don't use it always attack Linux on the internet

Lasse

people are too used to click the next button

Aidan Mueller

So do I (I have played with linux a little)

Lasse

I've been using linux servers for several years before I started using it on desktop

So I got enough experience to install Arch straight from the start

hasherr

I'm off to bed

Later.

Aidan Mueller

3:45 AM

I like being able to just type "sudo apt-get intstall <c++ library that is a paint to install on windows>" and it installs it for you

Lasse

And I don't think I'll be able to use anything other any more, maybe only if something better comes up but Arch has the best policies and stuff

Aidan Mueller

Bye hasherr

Lasse

yeah debian's aptitude is good

but I like Arch linux's pacman more

pacman -S program

Aidan Mueller

pacman?

Lasse

pacman -Syu updates whole system

Aidan Mueller

3:46 AM

That is halarious

Lasse

and it's rolling release

Aidan Mueller

I would get it just for the name

Lasse

pacman has nice easter egg, you can enable from config some ASCII art where you have C eating some pills while installing

it works as a progress bar

Aidan Mueller

Haha

If you type in "apt-get" it says "this apt has super cow powers" at the bottom of the help page

Lasse

yeah

Aidan Mueller

3:49 AM

Then if you type "apt-get moo" it draws an ASCII cow and says "have you mooed today"

Lasse

lol

Aidan Mueller

I wish that all distributions had the same package manager

they could pick the best one

Lasse

I think pacman is the best one, but it would be now really hard for debian to convert

or debian derivatives

Aidan Mueller

It just doesn't make sense to have hundreds and hundreds of package managers

At least share the same repository

Lasse

Well that's how open source world works

if someone does not like something, feel free to create your own

Aidan Mueller

3:52 AM

(I have learned how to use italics now)

Lasse

Sharing repos would be not good

Aidan Mueller

In this case that's a bit of a problem though

Lasse

Different distros have different file systems

Aidan Mueller

I guess it could have it's benefits

...

trying to think of one

Nope

Lasse

For example debian puts http server websites in /var/www but arch puts them in /srv/http

by default

6am already, brb gonna grab coffee

Aidan Mueller

3:55 AM

@Lasse But it doesn't change things like usr or home does it?

Ok

The reason I don't think that multiple repositories is good idea is because if we just had one (or at least a smaller number), using Linux would be a bit more universal.
