New Projects - Fresh from the Labs
Projects at a Glance
Much like Midnight Commander captured the feel and essence of the popular DOS application, Norton Commander, UnixTree models itself closely on the once popular XTreeGold. XTreeGold was the introduction that many first PC users had with DOS, which, much like Norton Commander, had a semi-GUI interface to ease the transition into a tricky environment. Although this may not strike an instant chord with command-line purists or full-blown X users, I know a number of people for whom XTreeGold was their primary interface day to day, and hopefully, UnixTree will ease their transition into the UNIX shell in the same way XTreeGold did for DOS. I've had a chance to use it, and I'm quite impressed, especially as certain essential UNIX commands are assigned to single keystrokes to speed up your daily command-line usage.
Anyone who has a mobile phone will know the time-old classic game, Snake. I still play the popular X game Gnibbles from time to time, and I've always had a soft spot for the style of gameplay. Gnake brings that gameplay to the console in a rather simplified form, but still, it's damn hard. Compilation is easy; simply grab the tarball, enter make and then ./gnake. I'm not sure whether the levels progress (I haven't passed stage one), but some of the options that can be altered include the playground size, speed, number of apples, growing length and the ability to add computer-controlled snakes.
Console Commander (concom.sourceforge.net)
Console Commander brings you a selection of information and system tools under an easy-to-navigate group of menus that should be of serious comfort to anyone not familiar with the Linux shell. Some of the clever features group together the sorts of information I've always had to dig through large GUI programs to reach, like Kinfocenter. Information, such as CPU type, free memory, partition usage, distro info and so on, is usually a pain to hunt down individually. Combined with tools that automate tasks like package and repository upgrades, how-tos and many more features, this is a handy program indeed. Although there's nothing technically amazing happening here, it has no pretenses about what it is and will save time for many users. I love it.

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
