There appears to be a Java port of SVDLIBC:

Re: Connecting SLIME a remote Clojure Repl

Kyle, this is a great post and is likely to help a lot of folks.

One minor point, I'd recommend changing "image", as in "Lisp image", to "process." In the Common Lisp world, it's frequently the case that you have a Lisp process that loads (and can save to) an image - unfortunately, the JVM doesn't include image loading/saving and thus Clojure lacks it.

"BigTable clone" is too fuzzy a term. I meant a distributed, scalable storage database for structured data [1].

Tokyo Cabinet is certainly lower level than BigTable, but I don't know how else to refer to the Tokyo Cabinet stack that mixi.jp (essentially the Japanese version of Facebook) uses. It includes Tokyo Cabinet, Tokyo Tyrant, and Tokyo Dystopia.

The exposed scaffolding and simple design make managing a TC-based database less scary than other more opaque designs.

If you haven't checked it out yet, their presentation slides [2] might inspire you to see how TC could be used as a BigTable stand-in for web applications.

1 - To make things even clearer I'll add: the database is not limited to row-oriented storage, lacks a fixed schema, and supports column indexes.

If you haven't yet, you may want to check out Tokyo Cabinet. Out of the promising, open source BigTable clones (Cassandra, Hypertable, Tokyo Cabinet), it appears to lead for the sort of performance you'd want to back a web app and is the maturest.

Re: Why Make Erlang a Functional Language?

Matt Revelle — Fri, 27 Jun 2008 09:55:05 -0000

Functional programming doesn't require syntax as messy as Erlang's [1] and Prolog, from which Erlang's looks were taken, is a logic programming language.

Also, Erlang's ugliness in referencing functions as arguments [2] is pretty annoying for a FP language.

[1] See Haskell, ML family, or Clojure.

[2] "fun someFn/<arity>" instead of "someFn". A good example of coding for the compiler.

It could cause a drop in readers. It depends on where YC wants the site to head: should it be constantly updated with the latest news, no matter how trivial? or feel more like a journal and suffer from a delay. Of course, there's no guarantee that slowing things down will help.
