Movie Making on a Linux Box? No Way!
Years ago there were these HPUX, IRIX and AIX boxes in the back of college computer labs that did nothing but basic computer infrastructure tasks: file serving, database management, number crunching and maybe a bit of eye candy here and there. If you wanted all of the fun stuff, you had to reboot a Windows PC a few times and wait for the horrendously slow 75Mhz Pentium chip.
But the UNIX boxes were so much faster and efficient than PCs of the time, and a UNIX box editing sound and video seemed like it would transcend all concepts of speed. However, no such software existed. Nothing existed to unify all those efficient utilities and system drivers into a single purpose. Getting a C program that could shuffle gigabytes of sampled audio and video data around in a system, and compile from scratch on thousands of variants of UNIX seemed like the perfect plan.
Windows and Mac advertisements constantly push ways to convert your Windows and Mac workstations into a movie studio. Meanwhile Linux was still pretty much adopted as computer infrastructure glue. If you scour the Internet, however, you might see a few people putting movie studios into a Linux box.
Broadcast 2000 is the Linux movie-making spinoff of mainstream computing in 2000. What Broadcast 2000 does is turn your Linux box into an iMac, a system able to capture, edit and render high-quality multimedia content. The software catapult you into a fury of content sensations normally reserved for those who earn their living by rebooting WinNT.
The Broadcast 2000 software allows you to cut and paste hours of full-motion, full-resolution movies and DVD-quality sound in an instant. The software spits out 2 gigabyte movie files like poptarts. It exercises the full potential of Linux, and most importantly it crosses the barrier between pure computing infrastructure to productivity applications, which is a challenge akin to landing a human on Mars.
Trailers from before 1998 can be transcoded to uncompressed Quiktime by xanim, an exporting edition. Since only the video track has a play icon, only the video plays back. Since each track has a record icon, each track is affected by selections.
It is hard to get programmers who choose Linux based on its tight implementation of basic computer science to focus on movie studio programs. It is even harder to get corporations to support productivity applications in Linux. Impossible tasks like this usually require brute force: sponsors, venture capital and old fashioned full-time programming.
But given enough brute force, Linux boxes can be found recording TV shows, editing commercials, editing home movies, arranging audio CDs, transcoding movies between formats, recording time lapse movies, archiving VHS tapes and playing directories full of MP3s. So which activity is going to enthrall you the most? Probably the installation, right?
The preferred method of installing Broadcast 2000 is to download the RPM and invoke
rpm -U --nodeps --force <filename>
All you have to worry about is matching the following libraries to the point release:
XFree86 4.0.1<\n> Linux Kernel version 2.2.17.Most problems occur with the RPM command usage. The three options are mandatory since RPM does not cope with the point release fragmentation in the operating system.
E-mails to the Broadcast 2000 support staff usually deal with having an RPM system on the Linux box or not having root access. There is an archaic utility called rpm2cpio that substitutes for RPM on these systems. You invoke it in the following sequence:
rpm2cpio <rpm file> | cpio -i --make-directories
This creates a mini usr tree in your current directory, containing a complete installation. Invoke ls -lR usr to view the complete directory tree.
Be sure to relocate the installation to the real /usr directory if you have root. Trying to install Broadcast 2000 without root can be very difficult if you are not familiar with runtime libraries. It is worth it to buy your own Linux box so that you can get these problems out of the way.
The script file usr/local/bcast/bcast2000.sh contains the proper runtime library path. If you relocated /usr/local/bcast you must change BCASTDIR to the new location of /usr/local/bcast/.
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
