Watching the Net's background radiation   25 Sep 04
[print link all ]
(Source: The Register) When the city sleeps, it’s never completely silent. But when the Internet sleeps, what kind of static does it make? What does it sound like? Like the weird warbles astronomers claim to hear from outer space?

We’d like to share what the Internet sounds like when it sleeps, and in its current highly agitated state, we think it’s worth sharing.

Rapid Application Development with Mozilla   25 Sep 04

This Prenticall Hall book by Nigel McFarlane can now be downloaded complete from the internet:

XUL can give a richer widget than HTML. For a nice application look at the Amazon browser. The author says on its webpage: 6/03/2003 I discovered XUL some months ago, when I found the O’Reilly’s book "Creating Applications with Mozilla", freely available at . I started to read the book and I understood that in my daily web development I could use all widgets I’m used to have in desktop applications. When I develop Content Management System, Control Panel, and Web Administrative tools, I find myself spending a lot of time designing the interface to reproduce the most basic widgets. Things like resizing the columns width of a data grid, make the application usable with the keyboard, scrolling result list with arrow keys, creating tab panels and so on, are not a so simple task in web development. I have to write or find somewhere a lot of javascript library and I waste my time in designing the basic interface when I want to focus on the business logic. I think web applications (that are a different things from public web site) should have a powerful user interface similar to the ones on desktop programs. XUL have almost all widgets. You can customize them using simple CSS or the GUI inherit the browser theme. I remind you that Mozilla is not just a browser, but a complete framework for building cross-platform applications. A big part of Mozilla is made with the same technology you can use in web applications: Javascript, CSS, XUL.   25 Sep 04

A Quick Guide to SQLite and Ruby   25 Sep 04
[print link all ]
why the lucky stiff has written a nice introduction to SQLite.

So, lets talk about SQLites handsome features:

  • SQLite is swift. In my own testing, I have found it to be speedy. Some speed comparisons with MySQL and PostgreSQL are here.
  • SQLite is not a large database server, such as MySQL. You dont connect to the database. Using SQLite, you access a database file. Everything happens in-process.
  • SQLite is an ACID database. Supports transactions, triggers.
  • SQLite is public domain. Absolutely no licensing issues.
  • SQLite is typeless. Any type or length of data may be stored in a column, regardless of the declared type. This allows extreme flexibility and avoidance of type errors.
  • SQLite allows custom functions and aggregates. This is my favorite feature of SQLite, which we will explore shortly.


[ANN] Net::SSH 0.0.2   25 Sep 04
[print link all ]
Net::SSH is an implementation of the SSH2 protocol in Ruby.

Version 0.0.2 brings the implementation to full compliance with the SSH2 protocol, since you can now use ssh-dss key types.

The most significant new feature is a limited implementation of the SFTP protocol. Only a subset of the features of SFTP are implemented, namely directory enumeration, and getting and storing files. More features are coming.

The SSH protocol itself is asynchronous, so the "core" implementation of the SFTP protocol (Net::SSH::SFTP::Session) is also asynchronous. However, a synchronous version (useful when you don’t need multiple channels open simultaneously) is also available (Net::SSH::SFTP::Simple).

Until Ruby 1.8.2 is released, you need to also install the patched version of the OpenSSL module for Ruby (also available from the Net::SSH site). Ruby 1.8.2 will include the patched version of OpenSSL, though, so once you have installed you’ll need nothing else to run Net::SSH.

[ANN] rpa-base 0.2.1pre1   25 Sep 04
[print link all ]
Mauricio aka batman at his best again!!! Make sure you check out the animation on the website.
 rpa-base 0.2.1pre1 is now available at .
 Many of the most popular libraries/applications as per Rubyforge
 statistics (rails, rake, redcloth, activerecord, sqlite, log4r, copland,
 ruvi, to name a few) have been packaged for use with rpa-base 0.2.1pre1.

 You can find a list of the 100+ packages at

 Screenshots and animations can be found at

 rpa-base 0.2.1pre1 fixes some issues in the bootstrapping phase, which
 couldn't hence be solved through the normal self-upgrade mechanism.
 In addition to several other bugfixes, 0.2.1pre1 features better proxy
 support, isolation of unit tests run automatically when installing a
 lib/app, and improvements in the command-line tool.


 The Ruby Production Archive (RPA) will provide packages of Ruby
 libraries and programs in a form that allows production use, engineered
 through a stringent process resembling FreeBSD's or Debian's.

 rpa-base is a port/package manager designed to support RPA. Its scope and
 purposes are different to those of other systems like RubyGems.
 rpa-base is a port/package manager designed to support RPA's client-side
 package management. You can think of it as RPA's apt-get + dpkg. It
 features the following as of 0.2.1pre1:

 * strong dependency management: rpa-base installs dependencies as needed,
   keeps track of reverse dependencies on uninstall, and will remove no
   longer needed dependencies
 * atomic (de)installs: operations on the local RPA installation are atomic
   transactions; the system has been designed to survive ruby crashes (OS
   crashes too on POSIX systems)
 * parallel installs: you can install several ports in parallel; builds
   will be parallelized and the final phase will be serialized properly
 * self-hosting: rpa-base installs and updates itself
 * modular, extensible design: the 2-phase install is similar to FreeBSD and
   Debian's package creation; rpa-base packages need not be restricted
   to installing everything under a single directory ("1 package, 1 dir"
 * rdoc integration: RDoc documentation for libraries is generated at install
   time (currently disabled on win32)
 * ri integration: ri data files are generated for all the libraries managed
   by RPA; you can access this information with ri-rpa
 * handling C extensions: if you have the required C toolchain, rpa-base can
   compile extensions as needed
 * unit testing: when a library is installed, its unit tests are run; the
   installation is canceled if they don't pass

 Several of the above features are illustrated in the screenshots and
 animations available at

 A number of features have been pushed back to 0.3.0:
 * full support for binary platform-specific packages
 * signed packages/ports
 * system-wide configuration system
 * better user interface
 In practice, the first one is the most limiting at the moment since it means
 that win32 users in particular need a working C toolchain to install
 extensions. This will soon be addressed.
