ShrinkIt

Company / developer:
  Andy Nicholas

ShrinkIt is a utility program for archiving files and disks. "Archiving", in this usage, refers to the process of placing files or disks "within" another file -- the archive file. Archiving is usually done to prepare the files/disks for transmission via modem, or for storage purposes. Thus, an archive file, whether created with ShrinkIt or another archiving utility, will be a file which serves as an envelope, containing one or more other files, or complete disks. There are a number of reasons for archiving files before transmitting them with a modem. The principal reason is that an archive provides a means of sending the "attributes" of a file -- its filetype and other information -- along with the file itself. An archive also allows several related files (or an entire disk) to be packed together into a single file. True archiving utilities will also have the capability of compressing the files they contain to minimize the transmission time and disk space the archive requires.

ShrinkIt uses a highly efficient compression algorithm known as dynamic LZW, and creates archive files with a format called NuFX. For technical documentation of the format of NuFX archives, refer to the File Type Note for filetype $E0, auxtype $8002. (File Type Notes are available from Apple Programmers and Developers Association.) ShrinkIt and ShrinkIt-GS are currently the standard archiving utilities for Apple II telecommunications. ShrinkIt can unpack files which have been archived with ShrinkIt, as well as those which have been packed with certain other file-packing utilities, such as BLU and ACU.

VMware Workstation

Expand the Power of Your PC with Virtualization

Discover the true power and flexibility of your desktop or laptop computer with VMware Workstation. Reduce hardware costs by 50% or more by running multiple operating systems simultaneously on a single PC. Automate and streamline tasks to save time and improve productivity. Join the millions worldwide who use Workstation to:

• Host legacy applications and overcome platform migration issues
• Configure & test new software or patches in an isolated environment
• Automate tasks for software development and testing
• Demonstrate multi-tier configurations on a single PC

Use Multiple Operating Systems Concurrently on the Same PC

VMware Workstation makes it simple to create and run multiple virtual machines on your desktop or laptop computer. You can convert an existing physical PC into a VMware virtual machine, or create a new virtual machine from scratch. Each virtual machine represents a complete PC, including the processor, memory, network connections and peripheral ports.

VMware Workstation lets you use your virtual machines to run Windows, Linux and a host of other operating systems side-by-side on the same computer. You can switch between operating systems instantly with a click of a mouse, share files between virtual machines with drag-and-drop functionality and access all the peripheral devices you rely on.

Take Snapshots & Videos of your Virtual Machines

With Workstation, you can take a “snapshot” that preserves the state of a virtual machine so you can return to it at any time. Snapshots are useful when you need to revert your virtual machine to a prior, stable system state. Workstation displays thumbnails of all your snapshots on a single screen, making it easy for you to track and revert to a previously saved snapshot.

You can even use Workstation 6 to record and play video files that capture all changes to a virtual machine over a period of time. This function is exclusive to VMware Workstation and is incredibly useful for software debugging, Help Desk forensics, sales demonstrations and training.

Run an Entire Multi-tier System on a Single Host Computer

Run multi-tier enterprise applications on a single piece of hardware by managing network-connected virtual machines with the Teams feature of Workstation 6. Teams let you create virtual network environments that include client, server and database virtual machines.

With Workstation Teams, you can turn an entire multi-tier environment on and off with a single click of the mouse button. Workstation displays live thumbnails of all connected virtual machines, enabling you to easily identify and switch between the virtual machines associated with a team.

Clone your Virtual Machines to Accelerate Deployment

Installing operating systems and applications can be time consuming. With clones, you can make many copies of a virtual machine from a single installation and configuration process. This capability makes it fast and simple to distribute standardized computing environments to employees and students, or to create a baseline configuration for testing.

Take Your Virtual Machines With You

New to Workstation 6 is the ability to create and deploy secure virtual machines (called ACEs) with the ACE Option Pack. Mobility is one of the primary benefits of this option pack, as it enables users to securely take their desktops with them on portable media devices such as USB thumb drives.

Netica

Company / developer:
  Norsys Software Corp.

Netica

Netica is a powerful, easy-to-use, complete program for working with belief networks and influence diagrams. It has an intuitive and smooth user interface for drawing the networks, and the relationships between variables may be entered as individual probabilities, in the form of equations, or learned from data files (which may be in ordinary tab-delimited form and have "missing data").

Once a network is created, the knowledge it contains can be transferred to other networks by cutting and pasting, or saved in modular form by creating a library of nodes with disconnected links. Of course, the networks and libraries may be saved in files or printed out.

Netica can use the networks to perform various kinds of inference using the fastest and most modern algorithms. Given a new case of which we have limited knowledge, Netica will find the appropriate values or probabilities for all the unknown variables. These values or probabilities may be displayed in a number of different ways, including bar graphs and meters. The case may conveniently be saved to a file, and later brought back into the network (or a different network) for further querying, or to take into account new information about the case. Netica can use influence diagrams to find optimal decisions which maximize the expected values of specified variables. Netica can construct conditional plans, since decisions in the future can depend on observations yet to be made, and the timings and inter-relationships between decisions are considered.

Netica can be used to transform a network in a number of ways. Variables that are no longer of interest may be removed without changing the overall relationships between the remaining variables (technically, the probabilities are "summed out" when we don't know the variable's value, and a more complex operation is used when we do). Probabilistic models may be explored by such operations as reversing individual links of the network, removing or adding causal influences, optimizing one decision at time, etc. These operations may be done with just a click of the mouse, which makes Netica very suitable for easy exploring, and for teaching belief network and influence diagram concepts.

There are many exciting new features and capabilities for Netica currently under development. Expect it to continue to be an industry leader in introducing new Bayes net capabilities over the coming years.

Unix

Company / developer:
  The Open Group

Unix

Unix operating systems are widely used in both servers and workstations. The Unix environment and the client-server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers.

Both Unix and the C programming language were developed by AT&T and distributed to government and academic institutions, causing both to be ported to a wider variety of machine families than any other operating system. As a result, Unix became synonymous with "open systems".

Unix was designed to be portable, multi-tasking and multi-user in a time-sharing configuration. Unix systems are characterized by various concepts: the use of plain text for storing data; a hierarchical file system; treating devices and certain types of inter-process communication (IPC) as files; and the use of a large number of software tools, small programs that can be strung together through a command line interpreter using pipes, as opposed to using a single monolithic program that includes all of the same functionality. These concepts are known as the Unix philosophy.

Under Unix, the "operating system" consists of many of these utilities along with the master control program, the kernel. The kernel provides services to start and stop programs, handle the file system and other common "low level" tasks that most programs share, and, perhaps most importantly, schedules access to hardware to avoid conflicts if two programs try to access the same resource or device simultaneously. To mediate such access, the kernel was given special rights on the system, leading to the division between user-space and kernel-space.

The microkernel concept was introduced in an effort to reverse the trend towards larger kernels and return to a system in which most tasks were completed by smaller utilities. In an era when a "normal" computer consisted of a hard disk for storage and a data terminal for input and output (I/O), the Unix file model worked quite well as most I/O was "linear". However, modern systems include networking and other new devices. As graphical user interfaces developed, the file model proved inadequate to the task of handling asynchronous events such as those generated by a mouse, and in the 1980s non-blocking I/O and the set of inter-process communication mechanisms was augmented (sockets, shared memory, message queues, semaphores), and functionalities such as network protocols were moved out of the kernel.

LightWave

Company / developer:
  NewTek, Inc.

LightWave

LightWave (or, more properly, LightWave 3D) is a computer graphics program for 3D modeling, animating and rendering.

LightWave has rendering abilities and unusual user interface (for example, icons are not used; instead functions are all given descriptive titles).

LightWave was one of the first high profile industry standard 3D packages featuring a built-in radiosity render engine, complete with a complex light calculation model for support of caustics.

Some functions within LightWave are multi-threaded, which means that those components can simultaneously use multiple processors in the same machine when performing complex calculations.

Programmers can expand LightWave's capabilities using an included SDK and also a special scripting language called LScript. This SDK is based on the powerful C language and almost anything can be created, from a custom shader to a different scene format exporter. LightWave itself includes dozens of free plugins and many more can be obtained from different developers around the globe.

Modeler and Layout

Unlike other 3D packages, LightWave is composed of two separate programs: Modeler and Layout. Each program is specifically designed to provide the most efficient workspace for specific tasks. Appropriately, Modeler provides tools for creating 3-dimensional objects, whereas Layout provides a workspace for lighting, animating, and rendering. When the two programs are running simultaneously, a feature called the Hub can be used to automatically synchronize data between the two applications via TCP/IP protocol.

Layout contains the LightWave renderer which provides the user with several options including Ray Tracing options, multithreading, and output parameters. This differs from most 3D computer graphics packages such as the popular Maya and 3D Studio Max, whereas they contain the renderer and the modeler all in the main program. This attributes plenty of versatility to LightWave as the user has several specific options they can customise via either program. It creates less confusion as well, and can provide easier methods of organisation.
