Linus Torvalds Releases Linux 1.2.0
Linus and others are working on support for multiple platforms, including DEC's Alpha, Sun's Sparc, MIPS' R3000 and R4000 series, and IBM and Motorola's PowerPC. Support for Amigas and Ataris with the Motorola 680x0 CPU has become relatively stable recently, and work is progressing on merging that work into the standard development kernel. DEC has funded a small team of programmers to work on porting Linux to the Alpha, and has loaned an Alpha machine to Linus. They are working in parallel. The DEC team has already released a 32-bit version of Linux that can run some programs, and Linus has released a 64-bit version that can run some Alpha OSF/1 binaries, and has successfully run GNU Bash.
Many Linux developers have been working behind the scenes on more performance enhancements and additional functionality that they would like to add to Linux 1.3.x. Linus has indicated that disk-space quotas, considered essential by many people who use Linux to run public-access systems, will probably be added during 1.3.x development. Further improvements to networking are being designed by Alan Cox, the main networking developer. Donald Becker, the developer of most of the Linux ethernet drivers, is working on some 100MB/s ethernet drivers that are likely to be added to 1.3.x. Work on wide SCSI support has already been started. More “intelligent” (or co-processing) serial adaptor drivers will be added. New hardware devices are being added all the time, and it is reasonable to expect that quite a few new supported devices will be added during 1.3.x development.
Not necessarily in version 1.3.x, but at some point in the not-yet-determined future, Linus has mentioned support for systems with multiple CPU's, such as the dual Pentiums being sold by many vendors now.
Of course, all the exact predictions here are the predictions of the author, and should be “taken with a grain of salt”. We can expect that the Linux developers have more nice surprises in store for us, some of which they haven't yet thought of.
The Linux dosemu development team reported that their current development version of dosemu (runs DOS, and DOS programs, from within Linux) runs the 32-bit Borland C/C++ compilers. They also report being able to run several 32-bit DOS-only games that they had been told would be impossible to run in dosemu. The list of games posted included: DOOM, DOOM2, Mortal Kombat, Mortal Kombat 2, OMF 2097, Raptor, Wacky Wheels, and Rise of the Triad. (Note that Id software has also made native versions of Doom available for Linux.) Of course, common DOS applications like WordPerfect still run, too.
The team intends to have a public release of dosemu ready within a month or so; hopefully dosemu 0.60 will be available for ftp from tsx-11.mit.edu in /pub/linux/ALPHA/dosemu/ by the time you read this. They are currently looking for volunteers to help them write documentation, and they will probably still be looking for volunteers to help with this large task by the time you read this; if you are interested, download dosemu and contact the team leader, James MacLean, email@example.com.

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
