15:03:04 <adu> hi
15:07:09 <speuler> hi adu
15:16:30 <adu> hi
15:18:46 <adu> how easy is it to write a parser in forth?
15:20:53 <speuler> may depend on whether the parsed text is such that you can use the interpreter, as opposed to writing a string scanner
15:23:55 --- quit: Fare (Ping timeout for Fare[ppp6-net1-idf2-bas1.isdnet.net])
15:24:01 <speuler> clog, fetch stick
15:27:09 <adu> hahaha
15:27:33 <adu> i'd want to use a string scanner
15:29:33 <speuler> parsing a line for a leader (such as arg=) and returning the argument is not difficult
15:29:48 <speuler> is that what you want ?
15:42:12 <adu> hmm
15:42:14 <adu> maybe
15:48:30 <speuler> s" -foo bar -irrelevant text"    2dup   s" -foo" parse type    ( bar )
15:48:55 <speuler>         s" -irrelevant" parse type    ( text )
15:54:29 <adu> ooo wow thanx
15:56:43 <adu> does s" push a string on the stack?
15:57:04 <adu> i really wish i knew more about forth
15:57:11 <speuler> pushs adress and count of string
15:57:16 <adu> i only know OF
15:57:50 <adu> i know: "dev / ls" "words" and "see ..."
15:58:14 <speuler> what does "dev" do ?
15:58:25 <adu> and of course the stupid / * - + dup pop rot swap ...
15:58:36 <adu> dev opens up the device tree in OpenFirmware
15:58:44 <speuler> oki
15:58:50 <adu> and sets the current dev  to /
15:58:58 <speuler> stop-a to invoke ?
15:58:58 <adu> ls just lists the current device
15:59:10 <adu> stop? i don't know
15:59:21 <speuler> the top left key
15:59:31 <adu> a?
15:59:36 <speuler> stop
15:59:42 <adu> what are you talking about?
15:59:53 <speuler> sun keyboards
15:59:57 <adu> i don't have one
16:00:02 <speuler> thought so
16:00:09 <adu> PowerMac
16:00:21 <adu> G3
16:00:39 <speuler> what key to bring up the openformware prompt ?
16:00:42 <speuler> firm
16:00:56 <adu> i wish you could extend nvram into physical ram so you could make an OS out of forth.
16:01:19 <adu> opt-cmd(aka, meta)-O-F
16:01:41 <adu> i guess they want to make sure no newbies get there be mistake
16:01:48 <speuler> but, memory operations, like @ ! move   work on physical ram
16:02:02 <adu> ya, but Of loads from nvram doesn't it?
16:02:21 <adu> what other computers use OF?
16:02:29 <speuler> sun workstations
16:02:32 <adu> does intel?
16:02:35 <speuler> no
16:02:44 <adu> i thought alpha did too
16:02:55 <speuler> likely
16:02:59 <adu> hm
16:03:52 <adu> i wish they would realize that the x86 architecture is very bad...
16:04:06 <speuler> who is "they" ?
16:04:09 <adu> hmm
16:04:17 <adu> MS, Intel... etc
16:04:33 <adu> the people who are the main reasons it has been around to long
16:04:41 <adu> whoever else that may be
16:04:56 <speuler> so they design a cpu with another flawed architecture ?
16:05:01 <adu> which do you think is better? DMA or IRQ?
16:05:11 <adu> no, use one thats out
16:05:26 <adu> like maybe a ia64 arch with ia32 chipset
16:05:30 <speuler> consumers' choice
16:05:52 <adu> but IRQs are so arbitrary
16:06:04 <adu> there are so many people that complain about using them up
16:06:06 <speuler> don't by, and the flawed products are faded out
16:06:12 <speuler> buy
16:06:34 <speuler> buy different, and you're not affected
16:06:47 <adu> not tru
16:06:51 <adu> you are affected
16:07:24 <adu> because the choices that others make affect which is the most popular, which in turn affects what companies put effort into, which in turn AFFECTS ME
16:07:50 <speuler> do you have problems with x86 architecture as consequence from running powerpc ?
16:08:06 <adu> hmmm, maybe
16:08:09 <adu> i wouldn't know
16:08:23 <adu> i'm going to get a pentium machine soon
16:08:41 <adu> 1) because my dad wants to work on stuff at home and
16:08:54 <adu> 2) he wants me to have a good way to learn about x86
16:09:47 <adu> the ia64 has no Nbridge/Sbridge right?
16:09:48 <speuler> i can visualize you struggling against learning x86
16:10:01 <adu> i already know x86 asm a little
16:10:19 <speuler> as 2 separate chips, rather than one ? i wouldn't know
16:10:20 <adu> learning ppc asm sucks bigtime
16:10:42 <adu> speuler: they're hubs, not chips
16:10:57 <speuler> sb and nb are chips too
16:11:01 <adu> aren't they?
16:11:09 <adu> o, controlling the card?
16:11:13 <adu> o
16:11:15 <adu> r
16:11:17 <adu>  hub rather
16:11:34 <speuler> northbridge (like bx440) is cpu - ram - pci switch
16:12:12 <speuler> southbridge does isa, i/o etc
16:12:31 <adu> ya
16:13:05 <speuler> you can run northbridge of manufacturer a with southbridge of manufacturer b
16:13:53 <adu> cool
16:14:12 <speuler> "you" = "designer of cpu board"
16:17:12 <adu> i'd like to think so
16:18:06 <adu> but until i learn about electronics and get a kit
16:18:15 <adu> its kinda useless to try anything
16:19:09 <adu> i don't want to kill myself with elecronic manufacturing equipment, and i don't want my materials shortcircuting if i have a very badly places gate
16:19:25 <adu> s/places/placed/
16:20:13 <speuler> i've been doin' some low level shit like setting up north bridges
16:21:30 <adu> cool
16:21:44 <speuler> tedious
16:21:53 <adu> i like the big-long-everyhting pci bus method
16:22:34 <speuler> w/o any local ram ?
16:22:45 <adu> why is it that supirior products never win?
16:23:01 <adu> no, i think it has local ram
16:24:31 <adu> like like VHS and Microsoft
16:24:52 <adu> why couldn't Beta and Macintosh be in the forfront?
16:25:01 <speuler> or pc clones 
16:25:13 <adu> ya
16:25:43 <adu> n/m
16:25:46 <adu> i'll go now

20:11:00 <adu> isforth is hard to understand
20:11:28 <aaronl> not really
20:12:36 <adu> o hi, didn't notice you were here
20:12:54 <adu> i'm reading Chuck's first implementation essay
20:13:01 <adu> it describes the dictionary
20:18:23 <adu> aaronl: have you ever tried implementing forth?
20:18:30 <aaronl> no
20:19:40 <adu> i'm trying to make a ppc isforth

20:32:07 <adu> i did something like that
20:32:12 <adu> it was a shell script
20:34:55 <adu> funky
20:37:23 <adu> thats so wierd
20:37:34 <adu> thats totally different than mine
