This appears to be the audio of Matz talk at BYU right before RubyConf. The
video is available too here:
http://www.cs.byu.edu/...

Yes.

I like the

DONUTS WILL BE PROVIDED

in a font almost as large and heavy as the title
on the flier,

http://www.cs.byu.edu/...2006Fall/Yukihiro_Matsumoto_flyer.pdf

Anyone have the link for the slides? (The movie has very
high compression.)

Oops; the slides are on the colloquia page.

heh, we take our donuts seriously in Provo. :)
and, yes, they were good donuts (at least my maple bar was).

Is it really fair to say that the ruby program

print *ARGF

is the same as /bin/cat? When used interactively they are different:

$ cat cat.rb
print *ARGF
$ ruby cat.rb
1
2
3
1
2
3
$ cat
1
1
2
2
3
3
$ ruby -e 'ARGF.each{|line| print line}'
1
1
2
2
3
3

Also, with a lot of input, the memory usage will be very different,
since 'print *ARGF' slurps all input.

But even 'ARGF.each{|line| print line}' is a lot shorter than 50 lines of C!

:) but how many lines of C are hidden behind that 'ARGF.each{|line|
print line}'

For that matter, how many machine instructions behind those 50 lines of
C, and how many femto-turtles carrying out those instructions, and so on
all the way down?

For performance, write it in femto-turtles :).

I'm writing a DSL to manipulate the spacetime foam directly.
Performance above all!
