E.g. - (k4/q) http://code.kx.com/wiki/Reference/hopen shows how to open a file/proc. The rest of the wiki is quite useful including a references and tutorials for q. k5 uses operators instead of words li

<pre> And now with less snark :). K/Q/kdb+ deploys a single executable and some additional k code (Q is written in k) in < 600KB uncompressed. Admin is very simple. Multicore use is trivial Hot code updates/upgrades

A view can be thought of as a dependency expression. In version 3 of K there was a data driven GUI. The dependencies allowed one to to Functional Reactive Programming (FRP) quite easily. Unlike SQL, views in k are not limited to queries as

Make a request at kparc.com for the research version of k (k5). If that doesn't work download q/kdb+ from kx.com (Windows/Linux/Mac OS X). It can runk4. / k4 implementations of the Bell Labs benchmarks are available

I don't think so. Many of K's primitives operate on arrays using stride 1 access. Being cache-friendly accounts for much of the performance gains. In addition, K is written in ANSI C to maintain portability.
