Cyclades Corporation has released the TS400, TS800 and TS3000, the newest members of the TS-Series, which are console servers used for out-of-band management of console ports in server farms and clusters. Featuring the same software as the other TS servers, the TS400, TS800 and TS3000 feature 4, 8 and 48 ports, respectively, in a 1U rack space. The TS3000 combines SSH, IP filtering and RADIUS with off-line data buffering and break-safe operation. Each of the TS-Series can also be used as a PPP server to provide access to dial-up clients or telecommuters using analog modems.
webMathematica is software that allows users to add interactive calculations to the Web. With webMathematica, users can build web sites that provide specialized calculations for fields such as electrical engineering, compute and visualize data with a browser, deliver courseware and interactive books, and provide active functionality for technical documentation. Built on Java servlets, webMathematica is compatible with any web server, servlet engine or application server that supports Servlet 2.0 API or higher. It currently is available under a Professional or Amateur license for Intel-based Linux platforms, with other platforms to follow.

Terra Soft Solutions announced that Yellow Dog Linux version 2.1 is now available for PPC processors. Updates to this release include making the 2.4 kernel the default and providing NVIDIA GeForce 2 video support. Other new features and updates offered are KDE 2.2.1, XFree86 4.1.0, Mozilla 0.9.3, Ext3 journaling filesystem, support for ATI RADEON video cards and a web-based administration tool. The YDL installation now supports individual package selection and offers Mac-on-Linux 0.9.60, which takes the ROM imaged from the Mac OS partition.
Designed for notebook computers and mobile users, Atek Electronics' two-button Super Mini Optical Mouse is the smallest computer mouse available, measuring 1" × 2.5". It provides the precise cursor control of an optical mouse with the advantage of its small size to be more useful and productive than standard laptop touchpads, trackballs and stick pointers. The Super Mini has a polycarbonate plastic shell and a Kevlar-reinforced three-foot cord. Both the USB and PS/2 versions are compatible with Linux.
The newest version of Qt, version 3.0, has been delivered by Trolltech. Qt offers a software development environment to create a single source tree that runs natively on many platforms, now including Mac OS X. New features introduced in version 3.0 are, among others, the ability to build platform- and database-independent database applications; text engine that supports rich text input, editing and rendering; the Qt Designer GUI builder that supports main window development and includes an integrated C++ editor; Qt Linguist for translation of GUIs to different languages; and Qt Assistant for easier searches. Qt v.3 is available under Professional, Free and Educational licenses.
The Linux for Chemistry series (Volume 1) is now available from The Random Factory. Linux for Chemistry includes over 1GB of chemistry-related applications all precompiled and compatible with most recent distributions (Red Hat 7.x and SuSE 6.4 or later are recommended). Applications range from molecular visualization and data modeling, to reaction kinematics, spectroscopy and more. A comprehensive on-line documentation library also is provided. A graphical package installation tool is included, as are recent graphics and database releases, security toolkits and remote desktop tools. Linux for Astronomy and Linux for Biotechnology also are available.
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
