04:40:24 <RodgerTheGreat> not bad
04:40:59 <RodgerTheGreat> I have a little backburner project for a boolean logic/ queue based language that's progressing pretty nicely
04:41:23 <RodgerTheGreat> I ought to have a finished interpreter in a week or two depending on how much free time I end up having.

05:17:46 <RodgerTheGreat> hi, Sukoshi- how's it going?
05:18:52 <Sukoshi> No.
05:18:59 <Sukoshi> :P
05:19:11 <Sukoshi> Taking a break after a hectic spring vacation of 70+ pages of homework.
05:19:43 <Sukoshi> And a Chip-8 emulator in a semi-finished state.
05:19:59 <RodgerTheGreat> ooh, cool! Chip-8 = fun!
05:20:08 <Sukoshi> Heh.
05:20:13 <Sukoshi> It's C though.
05:20:23 <Sukoshi> I'm too tired to bug hunt now.
05:20:24 -!- digital_me has quit ("Lost terminal").
05:21:08 <RodgerTheGreat> haha
05:22:28 <RodgerTheGreat> a friend of mine built a chip-8 emulator a while ago- his major stumbling block was how sprite collision worked. As soon as I explained the whole XOR register-flag-on-flip thing, he managed to get PONG pretty much working
05:27:42 <Sukoshi> Sprite collision?
05:28:23 <Sukoshi> You mean, if there's an already written-to portion of the screen?
05:28:47 <RodgerTheGreat> yeah
05:29:10 <Sukoshi> Well, the docs say ``if 1, then flip to 0, if 0, then flip to 1. Use XOR''
05:29:12 <RodgerTheGreat> it's actually a really clever way of allowing for "collision" with virtually no code
05:29:35 <Sukoshi> I know next-to-nothing about game programming.
05:29:39 <Sukoshi> But I know about processors :P
05:29:51 <RodgerTheGreat> yeah, and whenever you write a 1 to a pixel that's already 1, there's a register that's set to "flag" a collision
05:30:21 <RodgerTheGreat> I dabble a bit in game programming... <shameless plug>http://rodger.nonlogic.org/games/Neon2</shameless plug>
05:30:38 <Sukoshi> Yeah, VF.
05:30:59 <Sukoshi> I thought of a very nice approach to emulating the registers without making a huge case table to decide on the register based on the opcode.
05:31:59 <Sukoshi> I setup a u_int_8 v[0x10]; and then, say we have an opcode 8xnn called opc, v[(opc & 0x0F00) >> 8] = opc & 0x00FF;
05:33:23 <RodgerTheGreat> hunh
05:34:00 <Sukoshi> ?
05:35:53 <RodgerTheGreat> interesting
05:36:06 <Sukoshi> Aha.
05:36:14 <Sukoshi> Yeah, I was too lazy to create an opcode.
05:36:17 <Sukoshi> *opcode parser
05:36:24 <Sukoshi> **opcode parser proper
05:36:25 <Sukoshi> Gah.
05:36:35 <RodgerTheGreat> lol
05:36:45 <Sukoshi> Plus I wanted this to be as light as I could. Only two opcodes actually use arithmetic operations.
05:36:57 <Sukoshi> And no subtraction.
05:37:15 <Sukoshi> *as light as it could.
05:37:39 <RodgerTheGreat> I'll bet your compiler makes little purring sounds when you feed it your code
05:37:44 <Sukoshi> ;D
05:37:55 <Sukoshi> Bit-twiddling is my specialty. It always has.
05:38:04 <Sukoshi> Darn BCD code made me use arithmetic. Grr. I art angry.

22:20:21 <oklopol> python's inheritance... how do i access a parent? class b(a): ... self.a.? ... ?
22:20:35 <oerjan> super()
22:20:37 <oerjan> i think
22:21:16 -!- nazgjunk has quit (Read error: 104 (Connection reset by peer)).
22:21:34 <oerjan> or perhaps not, maybe you just use the name.
22:21:54 <oklopol> self is how you access the object itself
22:22:13 <oklopol> super seems to convert type -> parent of type
22:22:18 <oklopol> which doesn't help self
22:22:48 <oklopol> not that i necessarily need inheritance, i've never really liked it
22:22:57 <oklopol> just wondering, since it seems i'm using it :\
22:23:01 <oerjan> you can always look up things in a parent class if you know its name.
22:23:26 -!- nazgjunk has joined.
22:23:31 <oklopol> yeah, but i'd like to get the underlying parent object itself off the self
22:23:42 <oerjan> there is none i think
22:23:59 <oerjan> python is not prototype based.
22:24:26 <oerjan> the object contains a reference to the class, but there is no object corresponding to the super-class.
22:24:44 <oklopol> hmm... i'll go around that i guess then
22:24:45 <oerjan> just a reference from the class to its super-classes.
22:25:34 <oerjan> are you maybe asking how to call a constructor?
22:27:40 <oklopol> mm
22:27:52 <oklopol> i have copy() in my superclass
22:28:14 <oklopol> now my child class has copy too, i'd like to call the upper level copy there
22:28:37 <oerjan> right. do superclass(self,...)
22:29:14 <oerjan> any method call x.method(...) is equivalent to class.method(x,...)
22:29:50 <oerjan> *do superclass.copy(self,...)
22:30:14 <oklopol> global name superclass is not defined
22:30:48 <oerjan> by superclass i mean an expression giving you the superclass you want.
22:31:21 <oerjan> which might most simply be its name.
22:31:30 <oklopol> ah, yeah :P
22:31:32 <oklopol> indeed
22:34:03 <oklopol> can i promote a to easily it's child class b if b only adds functionality?
22:34:14 <oklopol> swap easily, to
22:34:33 <oerjan> what do you mean?
22:35:14 <oklopol> in the copy constructor i make the upper level copy... i need, however, return from copy() an instance of the child class
22:35:25 <oklopol> and the upper level copy() returns the parent
22:35:27 <oerjan> oh.
22:35:28 <oklopol> of course
22:36:13 <oerjan> right that is specific problem with copy.
22:36:40 <oklopol> mm maybe
22:37:15 <oerjan> the simplest might be to just change the class of the object, i think it is possible in python.
22:37:45 <oklopol> prolly, i'm just not familiar with that kind of twiddling
22:38:08 <oklopol> i'm not familiar with anything when it comes to python actually :P
22:38:45 <oklopol> i've learned the language by writing small functions for one-time use and read a quick tutorial
22:39:09 <oerjan> i think possibly the __class__ attribute can simply be set.
22:39:48 <oklopol> haha xD
22:39:51 <oklopol> it worked
22:39:52 <oklopol> :P
22:40:51 <oklopol> hmm... now the hard part
22:40:57 <oklopol> the part i have to do myself :\

22:59:42 <oerjan> are all those different programs or maybe you should get something with tabs?
23:00:22 <oklopol> not all of them are different programs
23:00:58 <oklopol> i mean, 70 processes, i only have 25 windows open
23:01:09 <oerjan> oh
23:01:49 <oklopol> but maybe 40 channels in irc, 100 seems a weird limit since this machine, from what i've heard, is not that bad
