space trader is what?

Space Trader (Palm OS)

Space Trader is a strategy game for Palm OS and Windows Mobile PDAs. It was released in 2002 by Pieter Spronck, a scientist at Tilburg University, and was inspired by David J. Webb's PalmPilot game SolarWars (which in turn was based on Matt Lee's popular Palm game Dope Wars) and the 1980s classic 3D strategy game Elite (though it does not have Elite's 3D flight mode). The game is free software under the GNU General Public License. Space Trader for Palm OS centers on buying and selling ten commodities in various star systems around the galaxy. The player has one of several types of spacecraft, and...

The simple part: Given an input string containing only printable ASCII-characters (space - tilde), count the number of occurrences of each character and return the result on any convenient format. The result for a string a%hda7a should be something like: a:3, %:1, h:1, 7:1, d:1. Sorting is unnece...

@DestructibleWatermelon I pass you a list of moves

zyabin101

Processes need to be re-run every so often.

You should just pass the opposing track-me file to each enemy, and make both processes asynchronously write moves in their own track-me file. Both file names are passed to the process.

@NathanMerrill ^

Nathan Merrill

13:29

Err, I'm going to use Java, not files. Also, moves will be chosen synchronously, because moves will be synchronous

zyabin101

Then how the first-to-move will know the second-to-move's plans?

Also, Java has files.

Qwerp-Derp

Learning some Processing!

Nathan Merrill

@zyabin101 I pass them to your function.

And files are slow, so no point in using them if I don't have to

zyabin101

@NathanMerrill So the first-to-move can't know the second-to-move's plans.

Nathan Merrill

Well P1 won't know P2's first move until he is picking his second move

zyabin101

void setup() {
  size(640, 480);
}

void draw() {
  if (mousePressed) {
    fill(255);
    ellipse(mouseX, mouseY, 8, 8);
  }
}

@Qwerp-Derp ^

This makes the mouse shoot tiny pellets.

Nathan Merrill

But P2's first move will occur after P1's, so if had it any earlier, he'd be planning moves based on future moves

zyabin101

Congrats, you just proved that the see-what-the-enemy-plans system is borked.

Nathan Merrill

It's not that unbalanced. Each round consists of 12 actions: 121212121212. I'm not even sure who has the advantage.

Qwerp-Derp

I think Processing deserves a better IDE than the original one

What if we make an IDE for Processing that's better than the default in Processing?

Nathan Merrill

P2 can respond to P1, but P1 gets the first move

Qwerp-Derp

Is anyone interested in making a Processing IDE?

zyabin101

@Qwerp-Derp Kinda easy, but

- we'd need to fork Processing,

- understand its source code,

- etc.

And we need a Java guy for all that.

wizzwizz4

@zyabin101 Jahvar is tehr bestht!

Qwerp-Derp

We use Processing to make a Processing IDE

If we're going to make one, we need:

wizzwizz4

@Qwerp-Derp ... That's not a bad idea.

zyabin101

13:50

@Qwerp-Derp Kinda easy, but

Qwerp-Derp

- a text editor (with proper highlighting for Processing)

zyabin101

- we'd need to find an eval() command in Processing.

All.

Qwerp-Derp

- something to eval the Processing code

wizzwizz4

@zyabin101 There is one.

We need to wrote a Jython extensions.

Qwerp-Derp

- editing the actual IDE ("hackable")

I'm starting to like Processing, but I don't like the IDE, and there's not a lot of options for me for a good IDE solely for Processing other than the builtin one

I don't really like Eclipse (never liked it)

And Atom support isn't really good

So this is actually going to be useful

So should we make an IDE?

quartata

@Downgoat @ConorO'Brien Can you recommend me a good arbitrary precision arithmetic library for JS? I'm kind of considering just emscriptening GMP/NTL but I worry about how slow it would be

Kritixi Lithos

^^ I tried creating a menubar (but I wasn't able to so I posted an issue on GH), but the creators of Processing told me that that was not supported and that I should try the Processing forum

There are multiple ways

@KritixiLithos Do I understand you correctly do you do understand the challenge, you just don't know how to do it?

Kritixi Lithos

I don't understand how you get (p∘q)(X) = p(q(X)) = X - 2X^5 + 3X^6 - 10X^7 +...+ X^16 ≡ X mod X^5

@flawr I don't understand the challenge itself completely, just sorta

flawr

You mean how X - 2X^5 + 3X^6 - 10X^7 +...+ X^16 ≡ X mod X^5?

Kritixi Lithos

Yes that

Sherlock9

p(q(x)) mod x^5 = x mod x^5

flawr

Well do you see that X^5 ≡ 0 mod X^5?

mod Q means that everything that is a multiple of Q is getting "zero'd" i.e. is equivalent to 0.

Since X^5 and X^6 e.t.c are multiples of X^5, we have X^5 ≡ 0 mod X^5, and X^6 ≡ 0 mod X^5 e.t.c.
