In case of CentOS5.2 default installation, rubygems is not availabe.

So, installation starts at rubygem, but it requires rdoc... anyway, let's go further.

Setup framework

install rdoc

    # yum install rdoc

Penetrate your firewall (port 3000 default)

in case of CentOS, iptables setup changed

# iptables -A INPUT -p tcp --dport 3000 -j ACCEPT

(if required) reverse proxy server setup

If you feel port 3000 specific-URL is ugly, you can setup httpd (apache) to reverse-proxy as below.

ProxyPass /ffp/ http://yourserver:3000/

ProxyPassReverse /ffp/ http://yourserver:3000/

Thus,

This error occurred while loading the following files:

but, we need SWIG before sqlite3.

The reason why SWIG is required, see http://www.machu.jp/diary/20070117.html

`install SWIG`



download from http://www.swig.org/download.html



# tar zxf swig-1.3.38.tar.gz

after all, I need to install following 2 packages (httpclient, json)

BINGO!!! now the application starts correctly.

I'm a user of HATENA-bookmark web service. It's a major social-bookmark service in Japan.
The API of the service is in public. So, I've written some code in Erlang.

To initiate operation, WSSE certification is required.
For details of WSSE specification, please refer
http://www.ibm.com/developerworks/webservices/library/specification/ws-secure/
For details of HATENA-bookmark API, please refer
http://d.hatena.ne.jp/keyword/%a4%cf%a4%c6%a4%ca%a5%d5%a5%a9%a5%c8%a5%e9%a5%a4%a5%d5AtomAPI?kid=88110#wsse (in Japanese)

Following is the wsse module.


 -module(wsse).
 -export([new/2]).

 -define(SHA1DIGESTLENGTH, 20).

new (User, Password) ->
    {A, B, C} = now(),
    random:seed(A, B, C),
    Nonce = nonce(?SHA1DIGESTLENGTH, ""),

%% create ISO 8601 compling datetime
%% $ ruby -e " require 'open-uri' ; p Time.now.iso8601"
%% => "2008-07-31T16:16:14+09:00"
%%
%%  ref) http://www.trapexit.org/Converting_Between_struct:time_and_ISO8601_Format 

    {{Year, Month, Day}, {Hour, Min, Sec}} = erlang:localtime(),
    TZ = os:cmd("date +%:z"),
    Created = io_lib:format("~4.10.0B-~2.10.0B-~2.10.0BT~2.10.0B:~2.10.0B:~2.10.0B~6s", 
 [Year, Month, Day, Hour, Min, Sec, TZ]),
    crypto:start(),
    Digest = binary_to_list(crypto:sha(Nonce ++ Created ++ Password)),

    "UsernameToken Username=\"" ++ User ++ "\", " ++
    "PasswordDigest=\"" ++
    base64:encode_to_string(Digest) ++ "\", " ++
    "Nonce=\"" ++
    base64:encode_to_string(Nonce) ++ "\", " ++
    "Created=\"" ++ Created ++ "\"".

nonce(0,L) -> L ++ [random:uniform(255)];
nonce(N,L) -> nonce(N -1, L ++ [random:uniform(255)]).

The HATENA-bookmark service API is using Atom format data.
Here is the module for it.

 -module(getatom).
 -export([new/3]).

new(User, Password, Uri) ->
 RequestHeader = [{ "X-WSSE" , wsse:new(User, Password)}],

 inets:start(),
 {ok, {{_Version, 200, _ReasonPhrase}, _Headers, Body}} =
 http:request(get, {Uri, RequestHeader}, [ ], [ ]),
 Body.

Here is a typical useage from erlang interpreter command line.

> Latest = getatom:new("username", "password", "http://b.hatena.ne.jp/atom/feed").
[60,63,120,109,108,32,118,101,114,115,105,111,110,61,34,49,
