Skype is a good VoIP program, that also does conference calls amongst several people reasonably well. It helps me cut down my phone bill :-). skype

I saw this post, dated May 16, 2004 by terminus, a skype staff member, which made me very happy. I am sick of running windows on my laptop only to use for skye. Now I can stay in good old Penguin-land.

 Skype is now starting a closed Linux beta. We are looking for forum
 members who would be willing to actively test the Linux version and
 provide input and feedback to finalize the Linux version development.

European Ruby Conference 2004. New date: October 8 and 9 in Munich

Register

Come for some Ruby-fun. Last year’s conference: www.approximity.com/cgi-bin/europeRuby/tiki.cgi/

 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 0.1.0 is now available on http://rpa-base.rubyforge.org .
 Please keep in mind that this is *not* a RPA release (that is, a release
 of the repository) but just a release of the rpa-base tool itself. We
 have provided several sample ports/packages for testing purposes, but
 they don't formally belong to RPA. Read below for information on the
 libs/apps packaged so far.

 rpa-base requires Ruby 1.8.1 (certainly 1.8 at least, it might work on
 1.8.0); it has been tested on several Linux distributions, FreeBSD and
 win32. We would appreciate feedback (both positive and negative) under
 those or any other architecture.

 It takes but a couple minutes to install and will allow you to do

 rpa install instiki ruvi

 ;-)
 (NOTE: ruvi, the cool pure-Ruby vim clone, won't work on win32)

 Features
 ========

 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 (working right now):

  * sane 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)
  * 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"
    paradigm)
  * 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 (currently disabled on
    win32)
  * 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

(Source: whytheluckystiff) The (Poignant) Guide is a new approach to teaching Ruby, emphasizing the lingual traits of Ruby and illustrating its uniqueness with comics, visual imagery, and songs with accompanying hand gestures.

This date marks the release of the first three chapters. Feel free to tell your friends and family (a.k.a. Slashdot) about the news. With enough input and support, this book could see completion by next year. Hopefully this is a step towards explaining to the world why Ruby is such an enticing and voluptuous gem to behold.

Go and enjoy the book

Okay, I’ll keep this short. If you want to read more about my motivation, head over to the announcement on my site. motivation

LinuxTag program

You can get Rake from rubyforge. If you have rubygems installed, then all you need to do is

  gem -i rake

If you have a very recent version of rubygems (i.e. from CVS), then the gen-rdoc option finally produces a decent rendition of the Rake documentation locally.

QuickStartExample

Some very interesting ruby stuff:

• Artificial Neural Networks: Implemented a multilayer backpropagating artificial neural network using a momentum term and optionally a weight decay term.
• Borges mod_ruby Integration: I have managed to get Borges running using mod_ruby. I will produce a library ready version of that and check it in the Borges project.
• and much more

This situation provides much of the motivation for our architecture, ERP5, which offers several advantages for business. All ERP5 tools are open source, so are free and have openly available source code that a business can change to suit its processes. ERP5 incorporates, from scratch, advanced concepts such as object-oriented databases, a content management system, synchronization, variations, workflows, and a method to model and implement business processes. ERP5 is also a Web site where researchers can share innovation on management techniques and their implementation through software.

In 2001, two companies initiated the ERP5 project: Nexedi, a Zope service provider in France (Zope is a well-known open-source application server), and Coramy, a European apparel manufacturer. They aimed to develop a set of ERP software components for small and medium-sized companies. In addition to source code, the project also produced educational material and a clearly defined theoretical model. To fit the needs of smaller companies, they also designed ERP5 for distribution across distant sites with slow and unreliable Internet connections.

Just look at the "eval.c" file, i think the require is defined there and then write your hook. Or write a dll/so and add embedd your rb files as large c strings there (using maybe the "wrap" tool from the Fox Toolkit) and then do rb_eval_string("my c file"). After this protect the dll with something like "armadillo" (use google to find the URL). This works perfectly for me.

Of course, the devil’s in the details: there’s inventory to manage, backorders to fulfill, outstanding invoices to collect, orders to process, bills to pay, and customers to service. The goal of business may be simple enough — but the business of running a business is anything but.

Fortunately, computers are a natural for the back office, and software to manage a business — called customer relationship management (CRM) and enterprise resource management (ERP) software — has become a big business in itself. SAP, Oracle, PeopleSoft, and Microsoft charge plenty of beans for bean counting software. For example, Microsoft’s Great Plains Software division charges $50,000 for a license, $100,000 for implementation, and $20,000 a year for maintenance.

But just as Linux has provided a free alternative to proprietary operating systems like Windows and Solaris, Compiere, this month’s "Project of the Month," provides an open source alternative to commercial CRM and ERP solutions. link

So hats off to Nucleus Research for firing a salvo at SAP for causing customers to shell out millions on software with little more than added worker productivity in return. link

Major features:

• Cholesky decomposition
• LU decomposition

• Linear equation solving
• Stand-alone LAPACK bindings: call any LAPACK routine from directly from ruby.

Source: _why, yaml.freepan.org) YAML is extremely simple to learn. The basics are extraordinarily simple. You may even find that you have unintentionally used YAML syntax when building lists or simple file formats.

It also helps if you have experience with any agile language (such as Ruby, Python, Perl or PHP). YAML was designed to suit these languages well and borrows a few basic ideas from them.

And look at the clock before you start. Jot the time down and we'll see how fast you are. [http://yaml.freepan.org/index.cgi?YamlInFiveMinutes]
