COBOL developers can now combine the benefits of the Linux environment with the application development features of ACUCOBOL-85 and take advantage of its many features, including: programmable hot keys, advanced window capabilities, a user replaceable file system and a built-in-source code debugger. Once an application is compiled in ACUCOBOL-85, developers can use Acucobol's full range of COBOL development tools and enjoy its portability to over 600 different platforms and operating environments without recompiling.
For more information, e-mail info@acucobol.com, send mail to Acucobol, Inc., 7950 Silverton Avenue, Suite 201, San Diego, CA 92126, phone (619) 689-7220, or fax (619) 566-3071.
Renegade Solutions has announced the availability of scientific instrumentation libraries for Linux. Currently offered are a basic driver for the Epix Silicon Video MUX series of video frame grabbing boards, a driver for a low budget serial port D/A and A/D device and a driver for a custom DSP board based on the TI C25 and C50 series DSPs.
The Silicon Video MUX family of framegrabbers provide up to 752x480 8 bit grayscale images making it suitable for demanding computer vision and research applications. The basic driver package includes a simple GUI program to demonstrate the boards capabilities as well as source code for the library, and is priced at $500. Motif based image editing, processing and analysis software is also available. The driver for the serial port module also includes a GUI demonstration program and sells for $200. A driver for a low cost DSP board built by FroZen Technologies is also priced at $200.
Renegade Solutions will develop custom drivers for the above hardware, as well as for other instruments. For more information, call Renegade Solutions at (208) 524-6440 or e-mail renegade@srv.net.
March 20, 1995—Darwin Open Systems today unveiled the OPEN LOOK, XView and NeWS Archive. This CD-ROM includes the full text of two books from the O'Reilly X series: the previously-unpublished Volume 3, User's Guide, OPEN LOOK edition, and Volume 7, XView Programming Manual. Both are on the CD in PostScript and in Adobe's Portable Document Format (PDF). There are also many other documents such as FAQs, and man pages for everything (included in troff, cat-able, PostScript and PDF, and usable from the CD-ROM by setting MANPATH). There is source code for the latest XView Toolkit, full source for many other OPEN LOOK programs and games including sample programs from several textbooks, pre-built search indexes for tools such as Glimpse, LQ-Text, viewers for PostScript and PDF, and other goodies. Also included is the full source code for two complete window systems:
The X Window System, Version 11, Release 6, (latest patch Level 11), including XFree86 (3.1.1.), and
The MGR Window System by Steve Uhler of Bellcore.
In addition to the textbooks, tool, and source code, there is an online “tour” of OPEN LOOK, XView, and other parts of the CD-ROM. The Tour is written in validated HTML, usable with Mosaic, Netscape, TkWWW, or your favorite Web viewer. If you are on the Internet, you can follow links to the outside. HTML hyperlinks are provided to the original FTP sources for much of the free software so you will be able to obtain updates, later versions, binaries for other platforms, etc.

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.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

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?
