No stranger to CAD on the Linux platform, VariCAD, now in version 2009 2.0, is a 3-D/2-D CAD system intended for use in mechanical engineering design. Core features include tools for 3-D modeling and 2-D drafting and dimensioning, libraries of standard mechanical parts (ANSI, DIN), calculations of standard mechanical components, and tools for working with bill of materials (BOM) and blocks. This version adds new features like improvements in the geometric constraint module, parameters and geometric constraints within solid creation profiles, parameters for angles within a Boolean tree and improvements in areas such as solid insertion and transformation, selection of parts and printing capabilities. A free 30-day trial version is available for download.
The latest iteration of Arkeia Network Backup, version 8.1, which is designed for hosting providers that seek to generate revenue by offering backup services to their customers, offers a range of new features. These include Custom Restore Objects (CROs) that allow system administrators to assign restoration rights to end users and extensible reporting (for example, preconfigured reports, new tools for custom report generation and more ways to receive reports). In addition, support has been added for AIX 6, Fedora 11, NetBSD 5.0, OpenBSD 4.5, Mac OS X Snow Leopard and Microsoft Windows 7.
New on bookstore shelves is the third edition of Jeff Duntemann's Assembly Language Step by Step: Programming with Linux, an introduction to the x86 assembly language. Although this new revision has been rewritten to focus on 32-bit protected-mode Linux and the free NASM assembler, the book retains Duntemann's distinctive lighthearted style as he presents a step-by-step approach to this difficult technical discipline. Duntemann starts by explaining the basic ideas of programmable computing, the binary and hexadecimal number systems, the Intel x86 computer architecture and the process of software development under Linux. From that foundation, he systematically treats the x86 instruction set, memory addressing, procedures, macros and interface to the C-language code libraries upon which Linux itself is built. The book assumes no prior experience in programming.
