Stomp::Error::InvalidFormatreceive failed

I think stomp 1.1.6 having some bugs! I installed stomp 1.1.3 uninstalling 1.1.6 to get rid of this issue!
Though weird solution but it works for me!

Install and setup PHPList

PHPList is an open-source newsletter manager, free to download, install and use. Follow this link to know more...
http://www.phplist.com/details
Here I'm trying to document how to set up PHPlist on Ubuntu that should work for other distributions with little modifications.

Setup Apache, PHP & MySQL:

Install Apache2 and PHP5

 apt-get install apache2 php5

Following NEW packages will be installed

 apache2 apache2-mpm-prefork apache2-utils apache2.2-common libapache2-mod-php5 libapr1 libaprutil1 libexpat1 libmagic1 libpq5 libxml2 php5 php5-common ucf

Install MySQL that must be 3.23 or higher

aptitude install mysql-server mysql-client libmysqlclient15-dev libapache2-mod-auth-mysql php5-mysql

The following NEW packages will be installed

apparmor apparmor-profiles libapache2-mod-auth-mysql libdbd-mysql-perl libdbi-perl libhtml-template-perl libmysqlclient15-dev libmysqlclient15off libnet-daemon-perl libplrpc-perl libterm-readkey-perl mysql-client mysql-client-5.0 mysql-common mysql-server mysql-server-5.0 php5-mysql zlib1g-dev

You will be also prompted to enter an admin password

Get strong one.

To check whether these packages installed or not, just fire

 dpkg --get-selections
 dpkg -L php5|apache2|mysql-client-5.0

To check whereabouts of MySQL

root@moinhaidar:~# find / -type d -name "mysql"

It will give you sth like this...

/var/lib/mysql
/var/lib/mysql/mysql
/var/log/mysql
/usr/lib/mysql
/usr/lib/perl5/DBD/mysql
/usr/lib/perl5/auto/DBD/mysql
/usr/include/mysql
/usr/share/mysql
/etc/mysql

Setup Database

Lets login to mysql we just installed

root@moinhaidar:~# mysql -uroot -p

Enter the password you fed while installation.
Now you should be on mysql command line as seen like this

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>

Create a database for PHPList namely myphplist

mysql> create database myphplist;
Query OK, 1 row affected (0.00 sec)

Grant privileges

mysql> GRANT ALL PRIVILEGES ON myphplist.* TO 'root'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

Check that out

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| myphplist          |
| mysql              |
+--------------------+
3 rows in set (0.00 sec)

Now its time to look into PHP installation. Create file say test.php using your favorite editor having

<?php
 phpinfo();
?>

Now fire root@moinhaidar:~# php test.php
Ooooo!!! You got an error like php not found! Okay lets install this package to get command line PHP.

 apt-get install php5-cli

So far so good!

Configuring PHP to Work With MYSQL

Again fire root@moinhaidar:~# php test.php and look for extension_dir something like below.

 extension_dir => /usr/lib/php5/20060613 => /usr/lib/php5/20060613

Now its time to find php.ini and get it configured...

 find / -name php.ini

Output should sth like this

/etc/php5/cli/php.ini
/etc/php5/apache2/php.ini

Open /etc/php5/cli/php.ini and search for extension_dir this should be sth like this

; Directory in which the loadable extensions (modules) reside.
;extension_dir = 

Uncomment if commented and set extension_dir what you find with root@moinhaidar:~# php test.php like

extension_dir = "/usr/lib/php5/20060613"

Setup PHPList

Get the latest version of PHPList

wget http://sourceforge.net/projects/phplist/files/phplist-development/2.11.5/phplist-2.11.5.tgz/download

Copy to appropriate loation, usually /var/www/ and untar/unzip whatever...

root@moinhaidar:~# mv phplist-2.11.5.tgz /var/www
root@moinhaidar:~# tar -xvzf phplist-2.11.5.tgz
root@moinhaidar:~# mv phplist-2.11.5 mylists

Now its time to configure ./mylist/config/config.php

[General settings for language and database]
$database_host = "localhost";
$database_name = "myphplist";
$database_user = "root";
$database_password = "dbpassword";
$installation_name = 'Whatever';


[Settings for handling bounces]
$message_envelope = 'noreply@yourdomain.com';
$bounce_mailbox_user = 'noreply';
$bounce_protocol = 'mbox';
$bounce_mailbox = '/var/mail/noreply';


[Security related settings]
$require_login = 1;


[Debugging and informational]
define ("TEST",0);
define('SEND_ONE_TESTMAIL',1);

Lets create new site namely phplist

root@moinhaidar:~# cp /etc/apache2/sites-available/default /etc/apache2/sites-available/phplist

Now "vi /etc/apache2/sites-available/phplist" and get it configure...
+ indicates new addition
* indicates modified

+ ServerName yourdomain.com
* ServerAdmin admin@yourdomain.com
+ ServerAlias *.yourdomain.com yourdomain.com
* DocumentRoot /var/www/mylists
#*Setting Off PHP safe mode in order to acheive bounce processing - site wise
php_admin_flag safe_mode Off

        Options FollowSymLinks
        AllowOverride None


        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
        + DirectoryIndex index.php index.html

Okay, Now enable mylists site and disable default one

sudo a2dissite default
sudo a2ensite lists

Now Check "vi /etc/apache2/sites-enabled/mylists", that should be same as sites-availabe one.
Installed IMAP module for PHP bcoz phpList bounce processing connects to your mail server via a PHP module called IMAP.

 apt-get install php5-imap

Checklist

#Create a temp dir
Create tmp dir to ./var/www/mylists/ if not there.
root@moinhaidar:~#
#Change permission
root@moinhaidar:~# chmod -R 777 /var/www/mylists

OAuth Twitter API: Post message , status 401 Unauthorized

   First thing first check out the access level. If its read only, fix it read and wirte both.

   If its already read and write then most probably you are doing post having read and write access but authorization is still of read only. Follow this link to revoke the access and reauthorize it again.

Twitter API And Extending Rails Contacts Gem To Invite Friends

Introduction:

Yet to install contacts gem?
OR, how to get it to play as plugin?
Follow this link...
Extending Ruby on Rails Contacts Gem to invite Facebook users
Got through?
Put twitter.rb into "#{RAILS_ROOT}/vendor/plugins/contacts/lib/contacts" containing...

class Contacts
 class Twitter < Base
  
  URL = "http://twitter.com"
  LOGIN_URL = "http://twitter.com/account/verify_credentials."
  ONTACT_URL = "http://twitter.com/statuses/friends."
  DMESSAGE_URL = "http://twitter.com/direct_messages/new."
  LOGOUT_URL = "http://twitter.com/account/end_session."
  PROTOCOL_ERROR = "Twitter has changed its protocols, please upgrade this library."
    
  def real_connect
   format = 'xml'
   api_url = LOGIN_URL + format
   url = URI.parse(api_url)
   req = Net::HTTP::Get.new(url.path)
   req.basic_auth(@login, @password)
   resp = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
     
   if resp.code_type == Net::HTTPUnauthorized
    raise AuthenticationError, "Username and password do not match!"
   elsif resp.code_type != Net::HTTPOK
    raise ConnectionError, PROTOCOL_ERROR
   end
     
   return true
  end
   
  def contacts
   format = 'json'
   api_url = CONTACT_URL + format
   url = URI.parse(api_url)
   req = Net::HTTP::Get.new(url.path)
   req.basic_auth(@login, @password)
   resp = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
     
   if resp.code_type != Net::HTTPOK
    raise ConnectionError, PROTOCOL_ERROR
   end
      
   data = resp.body
   data = Contacts.parse_json(data) if data
   return [] if data.empty?
   contacts = []
   data.each do |d|
    contacts << [d['name'],d['id']]
   end
   return contacts
      
  end
   
  def send_message(contact, msg, format = 'json')
   return "Direct Message must been less than 140 characters." if msg && msg.length > 160
   return "Direct Message must have something in it..." if msg.nil? || msg.length < 1
     
   api_url = DMESSAGE_URL + format
   url = URI.parse(api_url)
   req = Net::HTTP::Post.new(url.path)
   req.basic_auth(@login, @password)
   req.set_form_data({'user' => contact.last, 'text'=> msg }, '&')
   resp = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
   return true if resp.code_type == Net::HTTPOK
   return false
  end
   
  def logout
   #...
  end
   
 end
 TYPES[:twitter] = Twitter
end

We also need to pick appropriate JSON, if we are getting contacts in json format.

# Use ActiveSupport's version of JSON if available
if !Object.const_defined?('ActiveSupport')
  require 'json/add/rails'
end

class Contacts
  def self.parse_json(string)
    if Object.const_defined?('ActiveSupport') && ActiveSupport.const_defined?('JSON')
      ActiveSupport::JSON.decode(string)
    elsif Object.const_defined?('JSON')
      JSON.parse(string)
    else
      raise 'Contacts requires JSON or Rails (with ActiveSupport::JSON)'
    end
  end
end

Don't forget to add this into lib/contacts.rb

require 'twitter'

Done!

Usage

C:\Me\Workspace\contacts>ruby script/console
Loading development environment (Rails 2.3.4)
>> twitter=Contacts::Twitter.new('twitter-id','password')
...
...
>> contacts = twitter.contacts
=> [["Jeremy Piven", 20221159], ["The Next Web", 10876852], ["bob saget", 38536306], ["Joel Stein", 24608680], ["Moin Haidar", 38841828]]
>> contacts.each{|c|twitter.send_message(c, 'Your Message')}

All should be well :)
