into uses transient and persistent! for speed. The fact that into can take a
transient as input is an accidental consequence of that, I think. Before into
was changed to use transients internally, it could only take persistent data
structures as input, and return a persistent data structure.
I liked approach 2 myself, if the goal is to stick with pure functions when it
isn't too difficult. It avoids the comparison of 1, and gets you back exactly
the info you want to go onwards from there.

ascending order for :name, but explicit ascending
order for :salary:
(pprint (sort (multicmp :name [- :age] [+ :salary]) employees))
Thanks,

I've been going through the PLEAC web site, writing Clojure examples
corresponding to the Perl code examples from the Perl Cookbook:
http://pleac.sourceforge.net
Michael Bacarella started a github repo to collect these together, and I'm
helping flesh some of them out.

This is still early, but it might be in a form where someone would like to
use it, and I'd appreciate suggestions on what would make it more useful.
It is a fork of the clojuredocs client created by Lee Hinman, with some
additions so that you can either run it in the default "web mode", where it

It isn't hard to write your own variation of pmap that does not do more
parallelism than you want, regardless of whether the input sequence is
chunked or not. I wrote one for a Clojure submission to the computer
language benchmarks game a year or so ago. Besides avoiding unwanted
parallelism for
I would suspect that you would not get a _significant_ performance advantage
from specifying processor affinity, but if you really want to measure it and
find out by experimentation, read on.
I was not able to find any portable way within a JVM to set processor
affinity, after some amount of Googl
One benefit would be convenience of enabling parallelism on nested data
structures. One function at the top level could use parallelism, and the
pieces, perhaps handled by separate functions, and perhaps nested several
levels deep in function calls, could also use parallelism.
If it were implemen
I'll post more on this later, but I wanted to point out one case where I
found that pmap was not achieving the desired level of speedup (# of
CPUs/cores) that you would initially expect, and it is not due to any
reasons that I've posted about before.
Imagine a 4-core CPU. There are 4 physical CPU
Tal, did you consider the possibility of staying with Clojure 1.2.1 and its
libraries? Or was that not under consideration for some reason?

Pardon my ignorance -- I've not done anything with AJAX before. Is there a

If so, do you have an example of this I could use to learn from? Just two
