Freedom to Search
Free software may stem from a research mind-set, where shared results lead to a greater good. Free software has built this around various licenses such as GPL and BSD. The ideals behind free software have spread beyond software and can also be seen in other areas: documentation, game mods, illustrations, music - all types of content creation can be licensed in an open and free way.
One problem with all these licenses, as well as the plethora of closed and proprietary offerings makes it hard to find proper, open, material to start from when creating derived works. Here, creative commons enters the picture with CC Search. To quote the website, CC search is:
With CC Search, we give you quick and easy access to the freely licensed content available from many of the world's top content providers.
The metadata attached to our licenses allow content providers easy ways to search within their libraries for licensed content. ...
Recently CC Search has released a new beta version with a new interface. The goal of the redesign was to be able to be able to work with more search result providers.
Even if CC Search gives you a result it is important to double check that the license permits what you have in mind. Here, again, creative commons must be given credit. Their system with signs makes it easy to locate the license that you are after.
If you want to search for source code with a given license, try using koderz. The idea seems great, but I have no first hand experience in using the service in any real project (yet).

Practical Task Scheduling Deployment

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.
