Playterm, Platform of the Gurus
Did you learn all your Linux console skills from books or from forums? Or, did you peek over someone's shoulder to see the real action? Once in a while, we stumble upon new projects that deserve some attention, like Playterm. What's the reason for this command-line "peep show"? To spread GNU Linux command-line knowledge.
You will see a fair amount of on-line terminal recordings when you enter this site. The recordings cover several topics performed in the shell: tricks, one-liners, guided tutorials and handy utilities.
Personally, I found them quite entertaining to watch, and it brought me back to the BBS days. It can be educational, and also quite hilarious to see people making typos and mistakes.
Another interesting Playterm feature is the embed facility. You can upload terminal recordings on this site, which you then can embed and play on your blog or Web site. Optionally, you can allow commenting on your recordings, which, of course, will provide interesting hints and tips and other improvements.
The Coder of Salvation (Leon van Kammen) created Playterm because he was
just too curious about what people
were doing in their terminals. He used to work for a company where he did
extreme programming sessions with his colleagues through the GNU
In his experience, it is extremely educational when you work together in one terminal (and also entertaining).
In his opinion, console-related books and articles are great, but sometimes
it can be more helpful to see gurus at work.
If it were up to him, more command-line projects should feature a terminal
player on their sites:
"Why not? Why have only a tar archive on a site? Developers should make more
demos to show the world how cool their utilities are! It hurts me to see so
great utilities being overseen by the masses."
Obviously, these are the words of a true terminal evangelist.
Before the big Internet boom, people used BBSes a lot. People called to other people's BBSes via their phone line. The cool thing about running your own BBS was that you could create a console "intervention". By doing this, you could "take over" the terminal session of a given user. In those days, a lot of teaching and cooperation was done this way.
Playterm is still beta, but it's already fully functional. Currently, we are curious about how many users we can serve, but in terms of global Linux knowledge, we are very excited. At this point, Playterm.org is a nonprofit project to serve the community and spread GNU Linux knowledge. Hopefully, it will inspire youngsters to use the shell more often.
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.

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
