My friend Mike and I were talking a while back about Unix init systems
and came to the conclusion that mk's dependency tracking could come in
handy. I decided to implement it a few days ago using plan9port and
thought that some of the folks here might be interested. Although, I
still haven't
thanks for that. it is neat!
the comment in resample's man page is really true.
it produces great output s-l-o-w-l-y.
i needed to convert some pic(1)tures to transparent gifs.
unfortunately gif(1) doesn't do that. so i took a snapshot
of the page window with

I am having a hard time understanding the dircp script and the dup(3)
device. What's exactly the purpose of writing
@{builtin cd $1 tar cf /fd/1 .} | @{builtin cd $2 tar xTf /fd/0}
instead of
{builtin cd $1 tar c .} | {builtin cd $2 tar xT}
I also had a look to the pdf2ps script, and there, it
@{builtin cd $1 tar cf /fd/1 .} | @{builtin cd $2 tar xTf /fd/0}
instead of

; {builtin cd $one} | {builtin cd $two} ; pwd

please name one.
Your apparent lack of imagination surprises me.
Surely you can see that a whole range of applications becomes possible when
using a massively parallel system,

the /fd/1 and /fd/0 fererences ensure that dircp will work with ape's tar
which doesn't read/write stdin/stdout by default like plan9's does.

Great idea, I like it :) I'll have a look at the code later.
You're using it on old unix/linux not plan 9 I guess? thanks.

How do you plan to feed data to these 31 thousand processors so they
can be fully utilized? Have you done the calculations and checked what
memory bandwidth would you need for that?
There are reasons Pentium 4 has the performance you mention, but these
reasons don't necessary include the great

Reminds me of some project development teams.
Maybe Marvin Minsky was on to something.

Yep, I'm running it on my ~4 year old laptop. I'm curious to see how it
would compare on something newer though. I think it would still be I/O
bound, so I'm not sure how
If anyone does fancy working on gif(1) it has a bug I have been meaning to look
at for ages.
The problem relates to reproducing optimised animated gif files.
Gif(1) assumes each image in an animation should be rendered on a
black background, however optimised animations, those which contain

Instantaneous building of a complex project from source.

Depends on how complex. I spent two years retrofitting a commercial
parallel make (which only promises a 20x speedup, even with dedicated
hardware) into the build system of a

good story. it's hard to know when to rewrite.

The whole table was ganging up on Roman and his crazy idea, I believe
;). The objection mostly was to Intel dumping the complexity of
another core on the programmer after it ran out of steam in containing
parallelism
It turns out, the problem was just a shoddy
USB port. Using another one, printer works
fine. Also, the old timeout bug is no longer
there.
Thanks for your fine work and all the tasty
