The Gemcutter's Workshop
It has been another big bi-week, and the pace of the Ruby community is accelerating. The ruby-talk and rails mailing lists are full to overflowing, the ruby-core mailing list is quite active, project announcements seem to pop up on a daily basis, and new resources seem to appear overnight. It's an exciting time to be involved with the language.
Perhaps the biggest news of this bi-week is that Ruby will be represented in this year's Google Summer of Code. RubyCentral has stepped forward to act as an umbrella organization for Ruby mentors and students. A number of interesting-looking proposals already have been put forward. If you're interested in being a mentor or working on a project, you should head over to their Summer of Code page (www.rubycentral.org/soc2006) and see what's involved.
Eli Bendersky published a nice overview of blocks, procs and methods on his blog (eli.thegreenplace.net/2006/04/18/understanding-ruby-blocks-procs-and-methods). He said he felt like he didn't really understand them, so he set off on a voyage of discovery. Fortunately, he took good notes so the rest of us can follow along. Kevin Tew also went on his own trip through blocks and closures, and left notes for us on his blog (blog.tewk.com/?p=62). Between Eli and Kevin, we've got a pair of nice resources to help figure out closures, blocks, procs and methods, oh my!
James Gray put together a great post about Unit Testing in Ruby. It ended up being too long for his blog, so he posted it here: grayproductions.net/ruby/first_steps.html. James not only covers the basics of testing (and makes a strong case for doing it), but he describes the use of Mock objects quite well. If you're not a Unit Tester already, or if you're just a beginner, go read his article right away. If you've been testing for a while, it's still worth a read.
After two months of hard work, the LibXML team has cut a new release of the libXML bindings for Ruby. This library provides super fast, very functional tools for working with XML and XSLT. Although the library had stagnated for a while, the project seems to have been rejuvenated after a call for developers went out several months ago. The future looks promising for this project.
Hot of the heels of Canada on Rails, the Ruby and Rails communities gathered for the Silicon Valley Ruby Conference. This was more of a grass-roots activity, but it still pulled in some great speakers. A number of attendees provided coverage, among them were:
Ryan Davis (who also spoke): blog.zenspider.com/archives/2006/04/sdforum_group_n.html.
ones, zeros, majors and minors: ozmm.org/svrc.
In general, it sounds like this was a great conference. It's something more Ruby Brigades (or Groups, or Meetups or whatever you want to call yourselves--I prefer Brigades, so I'll stick to that) should look into. Whether you've got a strong group (like the Seattle.rb or NYC.rb), several groups in proximity (like the groups in Michigan or New England) or have a conference organizer nearby (as happened with the Vancouver Ruby Users Group and Canada on Rails), getting a regional conference together can be a great way to build Ruby awareness in your area.
One tantalizing rumor to emerge from the conference is that there's a book in the works on building Domain Specific Languages in Ruby from the Pragmatic Programmers (www.pragmaticprogrammers.com). If true, this should be a great book to add to your Ruby collection.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
