Comments:
<0> thanks a lot :)
<0> what device is used now?
<1> i had the same problem, except just not upgrading but building gentoo ;]
<0> fuser /dev/dsp is not in use anymore
<0> even if i play something
<1> ktne: not sure, maybe /dev/sound ..
<0> no such file
<1> or, i am not sure at all, the alsa is newer tso /dev is not in use maybe..
<0> i see
<0> now to install x.org :)
<0> i hate debian sarge. it's so outdated
<1> ktne: what distro?
<1> using debian? ;) Get Gentoo!
<0> gentoo takes a lot to build
<0> and it seems too complex to install
<1> hm not so complex
<1> if you are new - yes. but then you learn hwo linux generally works
<1> well, not linux - really hwo the system..
<0> well i know enough about how linux works
<1> i dont know anything at all how kernel works, very complicated stuff..
<1> ktne: gentoo is really fun
<1> http://wykis.com/wcms/Blog/view/27 :]
<0> well i'm working on my own small kernel :)
<1> I am enjoying gentoo much more than debian..
<1> ktne: are you? Third person today ;)
<0> :)
<1> how long was you working on it? what are the capabilities?
<0> well it runs a VM
<0> and in this VM i run my own programming language
<0> i have console and IDE disk access :)
<1> hehe :)
<1> ASM/C++ ?
<0> asm+c+my language
<1> any links?:]
<0> but my language has a really stupid compiler so i try not to use it too much yet
<0> no, it's closed source :)
<1> =P
<1> you made the compiler from c though, right?
<2> not my language :(
<2> printf("not my language :(\n");
<0> Drakas: pascal :)
<1> im php god ;} which means im crap at a or c++
<1> ktne: yee! :) Pascal rules
<0> Drakas: i find object pascal much better than c++
<1> pascal is much easier than c or c++ :)
<0> it's not because it's easy. i use it because it has very good debugging capabilities
<1> :) i still use pascal, its easier ;}
<1> so how do you create applications that create another applications? hwo do you create compilers?
<0> well a compiler just takes source code and outputs opcodes
<0> opcode = raw cpu instructions
<1> hm, not very nice - so the apps can control cpu directly? ;/
<1> can't it be like that apps send kernel messages of what to do and then, kernel p***es messages to cpu?
<1> ktne: how do you actually make it to output raw cpu instructions?
<0> there is a specific raw format defined by intel
<0> you just convert to that format
<0> (like jpg or bmp)
<1> ok. ;]
<0> then you feed those bytes into the cpu and the cpu executes them
<0> the cpu "knows" the format :)
<1> okey. can you actually run your kernel from grub ?
<0> yes
<0> but i don't use grub, i've wrote my own bootloader too
<1> hehe leader :D
<0> but i'll switch to grub in the future
<0> so that it's easier to boot
<0> it's more flexible
<0> my current bootloader is very limited. similar to that used by windows
<1> hehe ;) ktne being in competition with ms :0
<1> seems like one user needed to compete with a big company :D
<0> i don't try to compete with windows
<0> neither linux :)
<1> :D
<0> what's interesting about my os is that is specifically designed for my needs
<1> hm, do you know how to actually execute specific code straight to cpu which could be defined by the user (like javascript)?
<0> i don't care at all if no one else will use it :)
<0> yes
<1> can you tell me?:)
<0> javascript is run in an interpreter
<1> hehe, 'd love to have my own os
<1> ktne: well, interpreter. yes
<0> interpreters are easy to code but they are slow as hell
<1> about speed - i already knew, but still fast engough on 2ghz ;)
<0> first thing you have to do is to code a virtual machine
<0> first thing to do that is to define a bytecode format
<0> then you write an interpreter for that bytecode
<0> a bytecode contains a number of very basic instructions that can be executed
<1> meh, i forgot pascal overall ;)
<0> like addition, multiplication, etc
<0> pascal is not good for bytecode
<1> so what to do /:))
<0> you should use something like forth for bytecode
<0> i mean, you can write the compiler in bytecode
<0> err in pascal
<0> but don't execute pascal-like bytecode :)
<1> how do i make bytecode?:)
<0> the bytecode needs a standard first
<0> a format that you define
<0> on paper
<0> what command should do what
<1> ..for example ?
<1> oh commands yes, just basic ones. multiply etc..
<1> will make some crazy thing
<0> do you know basic?
<0> BASIC
<1> yes, had done a bit before
<0> you can do something like basic
<1> very basic ;)
<0> a very simple language
<1> hwo would you handle if functions etc.?
<0> then you convert let's say the javascript code to that very simple language
<0> well it's better to know how others do
<0> for example the x86 cpu does like this
<0> it has one instruction called Compare (CMP)
<0> you CMP two operands, like 2 variables
<0> then there is one special variable called EFLAGS that stores the result
<0> then you have conditional GOTO
<1> tmp 15; tmp 18; math multiply; set myvalue;
<0> do you know GOTO?
<1> yes, i do
<0> 1: a = 3
<1> used to mIRC script. now introduced in php 6
<0> 2: b = 4
<1> what if you have a block of instructions?
<0> 3 : cmp a,b
<0> you are jumping
<0> from one thing to another
<0> wait to finish :)
<1> i know =)
<1> the thing with me is that i dont know something. when a person starts it, i realize whole thing myself and then jump next ;] just like goto + 1000
<1> i am going to make my own simple interpreter
<1> will require very logical thinking ;)
<1> hwo do you split up a string in pascal, by a custom char?
<1> like php's explode..
<0> http://rafb.net/paste/results/yrbvvs72.html
<1> yes :)
<0> GOTO_IF_0 checks to see if eflags is zero, if it is then it jumps
<1> so simply i could make up an array and then use it's indexes that could be set by the goto
<0> unlike a normal GOTO that always jumps
<0> what are you speaking about?
<0> there i told you how to interpret an IF instruction
<1> yes i understand the thing now
<0> IF (a=b) PRINT("they are equal") else PRINT("they are not")
<1> :)
<1> got ya
<0> you transform that into bytecode
<3> what's this programming for noobs
<3> heh
<1> Lord-Voldemort: well?:) i am a noob (in c++) ;]
<3> heh
<0> Drakas: you have 4 types of GOTO: simple unconditional GOTO, GOTO_IF_0, GOTO_IF_POSITIVE, GOTO_IF_NETGATIVE
