11:45:42 <cleverdra> thanks for the update, aaron.
11:47:09 <futhin> heh
11:47:27 <futhin> i love idlers!
11:48:49 * aaronl is back (gone 00:03:27)
11:48:54 <aaronl> :P
11:49:17 <cleverdra> welcome back!
11:50:14 <cleverdra> curiously, has anyone here used Flux?
11:50:52 <futhin> what is it? :)
11:51:12 --- join: adu (andrew@adsl-63-201-89-237.dsl.snfc21.pacbell.net) joined #forth
11:51:34 <cleverdra> pringle.sphosting.com links to it.  Flux is a Color Forth system based on Enth, which is a native Forth system for pentium machines (though it works on this 486DX I have).
11:57:38 * cleverdra gasps.
11:57:54 <cleverdra> FP division is *faster* than integer division?  Is this true?
11:59:45 <futhin> yes
11:59:51 <futhin> assembler wise i think?
12:00:01 <futhin> or maybe i'm completely wrong :P
12:00:09 <cleverdra> No, you're right.
12:00:13 <cleverdra> That's crazy.
12:00:22 <futhin> uh
12:00:37 <futhin> on the machine level it's easier, i can't remember why tho
12:01:00 <futhin> ask eks :)
12:01:38 <cleverdra> eks?
12:04:41 <futhin> a guy on another chan, i'm asking him
12:06:33 <futhin> <eks> FP division is faster only when you interleave it with integer instructions
12:06:33 <futhin> <futhin> huh? interleave it?
12:06:33 <futhin> <eks> put non-fpu instruction in-between the fdiv
12:06:33 <futhin> <eks> fdiv == 70+ cycles
12:06:33 <futhin> <eks> while an equivalent float division in integer can be done in 35 cycles
12:06:36 <futhin> <eks> so you will win only if you use more than 40 cycles of non-fpu instruction after you fdiv
12:06:37 <futhin> <futhin> hmm
12:07:00 <cleverdra> <dhd> oh, I'm lying above.  PA-RISC has integer multiply, but it's done using the floating point unit (and FP registers)
12:07:21 <cleverdra> <dhd> Alphas don't have integer divide instructions, PA-RISC doesn't have integer multiply or divide instructions
12:07:37 <cleverdra> <dhd> FPU ops are faster on almost all modern CPUs actually
12:07:38 <cleverdra> <dhd> er, multiply and divide that is
12:07:43 <cleverdra> Thanks, futhin.
12:08:12 <futhin> hm :)

22:58:34 <aaronl> hi edrx
22:58:44 <edrx> hi aaronl
23:00:36 <edrx> would you like to help a bit on something about emacs-wiki?
23:00:46 <edrx> s/help/help me/
23:02:37 <edrx> aaronl: lemme explain: I'd like to install it in my machine, together with a copy of the contents of the emacs-wiki site, and of course publish the e-scripts on that to let more people play with it
23:04:07 <aaronl> i don't know anything about wiki
23:10:54 <edrx> ok - I thought you did cause you were always talking with johnw, but don't mind
