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.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
