bdb: Improved Ruby Bindings for Berkeley DB

Fri, 09 Jan 2009 18:28:29 +0000

Berkeley DB is a high performance database system initially developed in the early 1990s. It's not an SQL driven database engine - it just stores data in key/value pairs - but BDB is very fast, available to use on most operating systems, and is dual licensed for open source and commercial use. It has several benefits to just using a flat file or a PStore: transactions, fine-grained locking, replication, and hot backups, for starters.

While Ruby bindings already exist for BDB, Matt Bauer…

DebGem - Ruby Libraries Packaged for Debian and Ubuntu

Tue, 06 Jan 2009 16:34:53 +0000

Phusion, the company responsible for Passenger - the Rails deployment system, has today announced DebGem, a "RubyGem to APT conversion service."

Many Debian (and Ubuntu, which is compatible) sysadmins and users prefer to use the APT (as in apt-get) package management system for handling the installation of everything on their system. With its separate RubyGems packaging system, however, Ruby can cause a dilemma. While some Ruby stuff is available through the regular repositories, it can be out of date and unreliable. No longer.. DebGem…

Generate random password in Rails

Tue, 06 Jan 2009 12:50:32 +0000

http://railsgeek.com/2009/1/6/generate-random-password-in-rails

I am using Restful_authentication plugin for one of my projects.
As part of my user creation workflow, system should to generate a random password for the new user.
So, look at my password creation behaviour:

* generate uncrypted password
* send this with e-mail notification
* crypt the password

class CandidatesController < ApplicationController
...
if @candidate.valid?
candidate.save
Notifier.deliver_inv(candidate.email, candidate.crypted_password)
candidate.encrypt_password
end
end

require 'digest/sha1'
class User < ActiveRecord::Base
...
def encrypt_password
self.salt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{name}--")
self.crypted_password = encrypt(self.crypted_password)
save(false)
end
protected
def save_password
(self.crypted_password = password) unless self.crypted_password
end
...
end

class Candidate < User
# Callbacks:
before_save :save_password
before_validation_on_create Proc.new do |u|
u.password = Array.new(12) { (rand(122-97) + 97).chr }.join
u.password_confirmation = u.password
end

end

SourceClassifier: Identifying Programming Languages Quickly

Mon, 05 Jan 2009 14:44:20 +0000

If you're developing a snippets or pastie-type system or another form of CMS where source code might be stored, it'd be incredibly useful to automatically detect what language a provided source is in so that you can style it appropriately.

Chris Lowis' SourceClassifier (or Github repo) library does just that, using a Bayesian classifier trained on source code from the Alioth Shootouts. Out of the box it has support for C, Java, JavaScript, Perl, Python and Ruby, but you can train it to…

How to Sanitize HTML and CSS in Ruby

Thu, 01 Jan 2009 07:41:12 +0000

If you've developed an application that displays user-supplied text in a Web browser, it's always possible that the user has entered some crazy HTML (or even CSS) that will break your site's layout. While it's easy to remove all HTML from a piece of text, you might want them to use certain subsets of HTML to format their content, so you need to sanitize the user supplied HTML and CSS. Luckily, two Ruby libraries have been released in the last couple of days…
