If you already have an existing Erlang installation and want to use CEAN on it, you just need to download the CEAN library and extract the archive into your erlang lib directory. Windows users may better download a zip archive of CEAN library. Then follow the instruction from the FAQ. If you want to use CEAN and do not have Erlang installed, you need to install a minimal CEAN Erlang/OTP system co

an Erlang distribution system for both applications and Erlang/OTP framework. multi-platform: supports many operating systems and architectures lightweight Erlang: ~4Mb installed size for the minimal system easy to install: self extractable archive, automatic install/uninstall/upgrade using Erlang shell easy to use: don't care about modules dependencies, CEAN handles that for you usefull to creat

One of the joys of playing at being a publisher is that I get to mess around with the technology in books as those books are getting written. Lately I've been having a blast with Joe Armstrong's new Erlang Book. At some point I'll blog about the really neat way the Erlang database unifies the set-based SQL query language and list comprehensions (it's obvious when you think about it, but it blew me

酒日記 はてな支店 - Erlangでたらい回し を見て、memorize版を書いてみた。 memorize_tarai(X, Y, _Z) when X =< Y -> Y; memorize_tarai(X, Y, Z) -> case get({X, Y, Z}) of undefined -> put({X, Y, Z}, memorize_tarai( memorize_tarai(X-1, Y, Z), memorize_tarai(Y-1, Z, X), memorize_tarai(Z-1, X, Y))), get({X, Y, Z}); A -> A end. プロセスディクショナリを使ってみました。酒日記さんのと同じ測定方法で測定。 bench_memorize_tarai(X, Y, Z) -> {Time, Ans} = timer:tc(?MODULE, mem

■[Erlang]Reiaを試す via Simon Willison’s Weblog. Reia (pronounced RAY-uh) is a Python/Ruby-like scripting language for the Erlang virtual machine (BEAM). http://wiki.reia-lang.org/wiki/Reia_Programming_Language ということなのだが、「何だこれ？」感がぬぐえない。 導入 コンパイルにrakeを使うので別途インストールが必要。またescriptを使うのでescriptへのパスを通しておく必要がある。FedoraのyumでインストールしたErlangの場合、escriptは/usr/lib/erlang/bin/escriptにある。 $ git clone git://github.com/
