Some Ruby Before Christmas
'Twas the Saturday before Christmas and throughout Ruby-land
hackers were working, refact'ring by hand.
Their programs were written with the greatest of care
in hopes that a new VM soon would be there.
The newsgroup was still, the irc channels too
In light of the quiet, what's a blogger to do?
When up on the mail list, there arose such a clatter
I sprang to my laptop to see what was the matter.
When what to my wondering eyes should appear
but a great bunch of news before the New Year.
Well, Clement Clark Moore I'm not, but this has been a great couple of weeks for Ruby, and those of us who enjoy it:
- rubinius (the smalltalk inspired VM written by Evan Phoenix and a host of others) is moving fast and is drawing a lot of interest from Ruby-fans everywhere.
- Not to be outdone, Jruby (Ruby on the JVM from Charles Nutter, Thomas Enobo, and a large and active group of contributors) has just released version 0.9.2
- Mongrel (the super fast, super secure Ruby webserver) is sitting on the cusp of a 1.0 release thanks to the work of Zed Shaw and his cohorts.
- RubyInside published a Ruby Advent Calendar
- Ruby 1.8.5 p2 was released in response to a security vulnerability.
- Ruby development has moved from the old cvs base to a new SVN repository
- Jeremy McAnally has announced that he's releasing his Humble Little Ruby Book for free as a Christmas gift to the Ruby community.
I hope you're looking forward to a great 2007, full of Ruby goodness. Have a happy holiday season.
Update: I nearly forgot Jeremy McAnally's announcement (the last item on the list).

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
