MYDATA's Industrial Robots
Most of the hardware in the MYDATA machines is manufactured in-house. This hardware is impossible for the average person to buy and would be useless unless he had a MYDATA machine. For this reason, we have not made the device drivers publicly available. In any case, MYDATA hardware is already bundled with the most up-to-date software available.
We do, however, use two pieces of hardware that can be used by anyone: the Decision PCCOM-8 multi port serial card and the parallel port to SCSI conversion cable from Shuttle Technologies called EPST. We contracted Signum Support, a Swedish consulting company specializing in GNU software, to write device drivers for these two. The contract states the device drivers are to have the GNU GPL license and that Signum should try to include the drivers in Linus Torvalds' next kernel release. These drivers are currently available and fully functional. Contact Signum Support at http://www.signum.se/ for download information.
From a purely economic point of view, we get a lot of beta testers for these device drivers free of charge. Even better, we get to give something back to the Linux community.
From a programmer's and lawyer's point of view, MYDATA supplies four different software packages that interact.
The Linux operating system (free of charge)
The device drivers for MYDATA hardware (as loadable modules)
Servo programs (running on servo computers)
However, from the user's point of view MYDATA offers an industrial robot with hardware and a software system. The user is not usually concerned with implementation details such as the choice of an operating system.
Until now, the software installation and upgrades have always been done by service engineers. With the next generation of software we want to provide an installation CD-ROM which the user can use without a service engineer or thick manual by his side. The vision is that the user will insert the CD-ROM and the boot floppy, turn on the power and let the installation process automatically. Well, we might have to ask for an IP address. This installation CD-ROM is being developed in cooperation with Signum Support and is based on Red Hat 4.0 with a limited choice of hardware and added hardware detection.
MYDATA has managed to switch from an aging operating system to Linux with a reasonable amount of effort. In Linux we now have a modern operating system that will continue to grow with us for several years, and it gives us a solid foundation for future development.
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
