Brute Force Dictionaries in Ruby

Sun, 25 Oct 2009 15:56:09 GMT

module Brute
  def dict(word_size, alphabet)
    alphabet = alphabet.split('') unless alphabet.is_a?(Array)
    first = (alphabet[1] + alphabet[0]  * word_size).alpha_to_i(alphabet)
    last  = (alphabet[1] + alphabet[-1] * word_size).alpha_to_i(alphabet)
    (first..last).collect{ |n| n.to_alpha(alphabet)[1..-1] }
  end 
  module_function :dict
end

class Fixnum
  def to_alpha(alphabet)
    alphabet = alphabet.split('') unless alphabet.is_a?(Array)
    self.to_s(alphabet.size).split('').collect{ |n| alphabet[n.to_i] }.join
  end 
end

class String
  def alpha_to_i(alphabet)
    alphabet = alphabet.split('') unless alphabet.is_a?(Array)
    self.strip.split('').collect { |c| alphabet.index(c) }.join.to_i(alphabet.size)
  end 
end

Install Adium themes to Empathy

Tue, 22 Sep 2009 22:44:19 GMT

     #!/bin/sh
     # Adium theme AdiumMessageStyle installer for Empathy
     # Last version here: http://gist.github.com/191499

     if [ -z $1 ]
       then
     	echo
     	echo "	Usage:"
     	echo "		`basename $0` adiumxtra://some.url.here/extra"
     	echo
     	exit 1
     else
     	TMPDIR=`mktemp --directory`
     	XTRAURL=`echo $1 | sed -e "s/^adiumxtra:/http:/"`
     	DEST="$HOME/.local/share/adium/message-styles/"
     	if [ !-d $DEST ]
     	then
     		mkdir -v -p $DEST
     	fi
     
     	cd $TMPDIR
     	echo "Downloding extra..."
     	wget --no-verbose --progress=bar:force -O xtra.zip $XTRAURL

     	if [ -z $THEMES ]
     	then
     		echo "No themes found in downloaded file"
     	else
     		for theme in $THEMES
     		do

     		done
     		echo "\nTheme $XTRAURL was succesfully installed to $DEST"

Use gconf to enable this protocol handler for clever browsers:

gconftool-2 -t string -s /desktop/gnome/url-handlers/adiumxtra/command "/usr/loca/bin/adiumxtra-install %s"
gconftool-2 -t bool -s /desktop/gnome/url-handlers/adiumxtra/enabled true
gconftool-2 -t bool -s /desktop/gnome/url-handlers/adiumxtra/needs_terminal false

Works at least in Chromium :)

Ruby 1.9.1 for Ubuntu Karmic

Fri, 07 Aug 2009 01:02:45 GMT

Packaging of ruby 1.9.1 in progress, but if you cannot wait and want to test new features you can build the package yourself:

Installing build-dependencies:

 sudo aptitude install debhelper cdbs dpatch \ 
 patch autoconf m4 bison binutils libgdbm-dev \ 
 libncurses5-dev libreadline5-dev tcl8.4-dev \ 
 tk8.4-dev zlib1g-dev libssl-dev procps

Building the package:

 sudo atitude install devscripts build-essential
 mkdir /tmp/ruby191 && cd /tmp/ruby191
 dget https://launchpad.net/ubuntu/karmic/+source/ruby1.9.1/1.9.1.243-0ubuntu1/+files/ruby1.9.1_1.9.1.243-0ubuntu1.dsc
 dpkg-source -x ruby1.9.1_1.9.1.243-0ubuntu1.dsc
 cd ruby1.9.1-1.9.1.243 && debuild
 cd .. && sudo dpkg -i *.deb

And finally You can get it from Ubuntu on Rails PPA:

 sudo aptitude install ruby1.9.1 ri1.9.1 rdoc1.9.1 ...

and much more… :)

Graphical interface for SQLite

Sun, 02 Aug 2009 22:15:20 GMT

Today I improved rsqlitegui a little bit (original author is inactive since 2007 so i forked it on gitorious). Migrated it from Glade to GtkBuilder, made small refactoring and tail the code for setup.rb.

Package for Ubuntu Karmic is availible at PPA for Ubuntu on Rails Team.

SQLite GUI needs a little work and nice Tango-styled icon (anybody?).

Everybody loves screenshots:

PS: Git repository of the project at gitorious.org.

Client-side Syntax Highlighter for Rails

Wed, 15 Jul 2009 18:07:54 GMT

Just published my wrapper around SyntaxHighlighter2 (git mirror).

script/plugin install git://github.com/antono/sh2.git
rake -T sh2
rake sh2:install

Add following intro head section of your layout:

include_syntax_highlighter_assets(:themes => :midnight, :brushes => :all)

And this at the bottom of page:

sh2_highlight_code

This code:


  1000.times { puts 'Руби Руби Руби Руби' }

become this:

  1000.times { puts 'Руби Руби Руби Руби' }

Rake: undefined method `reenable' (resolved)

Sat, 16 May 2009 08:03:09 GMT

If you got something like

undefined method `reenable' for <Rake::Task db:schema:dump => [environment]>:Rake::Task

when trying rails migrations, you certainly should update your rake

sudo aptitude remove rake
sudo gem install rake

rndc: connection issue (RESOLVED)

Fri, 15 May 2009 06:22:29 GMT

After small experiments with dns caching daemons I back to bind9 and found out that rndc cannot connect to it.

rndc status
rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol,
* this host is not authorized to connect,
* the clocks are not synchronized, or
* the key is invalid

Checked that /etc/rndc.conf and /etc/bind/rndc.key matches. Rebooted bind but met the same problem.

After some investigation i found that port lwresd listening on 953 port.

netstat -atpn | grep -E ":953|:53"
pkill named
pkill lwresd
/etc/init.d/bind9 start

I hope this help you :)

Torvalds goes GNOME!

Sat, 24 Jan 2009 06:01:35 GMT

Linus Torvalds switched to GNOME:

I used to be a KDE user. I thought KDE 4.0 was such a disaster I switched to GNOME. I hate the fact that my right button doesn’t do what I want it to do. But the whole “break everything” model is painful for users and they can choose to use something else.

Shuttleworth on Capitalism

Mon, 24 Nov 2008 05:46:18 GMT

I used to be a fan of Adam Smith’s invisible hand, and great admirer of Ayn Rand’s vision. Now, I feel differently. Left to it’s own devices, the market will tend to reinforce the position of those who were successful in the past, at the exclusion of those who might create future successes. We see evidence of this all the time. The heavyweights that define an industry tend to do everything in their power to prevent innovation from changing the rules that enrich them.

Bundle all, David

Sat, 22 Nov 2008 21:13:18 GMT

This statement by David actually teases out a fundamental difference of opinion between Rails and Merb. In effect, Rails prefers to bundle everything to reduce dependencies, while Merb prefers to use the existing Rubygems system so that applications can use different versions of the “bundled” dependencies.

Even if it’s possible to give camelCase names to ruby methods and variables You should not do it!
