Yet, throughout this wonderful tapestry of living creatures, there runs a single thread: Deoxyribonucleic acid or DNA. The existence of DNA, an elegant, twisted organic molecule that is the building block of all life, is perhaps the best evidence that all living organisms on this planet share a common ancestry.
Our ancient connection to the living world may drive our curiosity, and perhaps also explain our seemingly insatiable desire for information about animals and nature. American Insects and searched through the section on moths and butterflies.
It was a luna moth! My heart was pounding with the excitement of new knowledge as I ran to share the discovery with my parents. Our own personal awakenings to the natural world are as diverse as humanity itself. I spent my early childhood in rural Iowa where nature was an integral part of my life. My father and I spent many hours collecting, identifying and studying local insects, amphibians and reptiles. These experiences had a significant impact on my early intellectual and even spiritual development.
One event I can recall most vividly. I had collected a cocoon in a field near my home in early spring. The large, silky capsule was attached to a stick. I brought the cocoon back to my room and placed it in a jar on top of my dresser.
I remember waking one morning and, there, perched on the tip of the stick was a large moth, slowly moving its delicate, light green wings in the early morning sunlight. It took my breath away. To my inexperienced eyes, it was one of the most beautiful things I had ever seen. I knew it was a moth, but did not know which species. Not wanting to suffer my ignorance any longer, I reached immediately for my Golden Guide to North The revision of these volumes could not come at a more opportune time.
In fact, there is a desperate need for a deeper understanding and appreciation of our natural world. Many species are classified as threatened or endangered, and the situation is expected to get much worse before it gets better.

Species extinction has always been part of the evolutionary history of life; some organisms adapt to changing circumstances and some do not.
Much of this projected growth will occur in developing countries in Central and South America, Asia and Africa—regions that are rich in unique biological diversity.
Yet, each time I encounter a new and unusual animal or habitat my heart still races with the same excitement of my youth. If this is biophilia, then I certainly possess it, and it is my hope that others will experience it too. A growing number of people live in urban settings and are becoming increasingly isolated from nature. Children and adults must be taught to value biological diversity and the habitats that support it.

Please Journal, inquiries, submissions, and requests to: December Hewlett -Packard Journal In this Issue The phenomenal growth and complexity of computer networks has created a wealth multitude opportunities for communication and resource sharing and a multitude of concerns about privacy and security.
Applications developed using the DCE software system are portable and interoperable over a wide range of com puters and networks. Applications running in DCE are also able to share data and services efficiently and securely regardless of the number of computers used in computer they are located.
The first eight articles in this issue describe the fundamental elements of DCE and security. In a DCE envi ronment, there might be several thousand host systems, some of which might be from different vendors, and many different categories of users and applications. To deal with this heterogeneous and diverse environment, DCE defines a basic unit of operation and administration called a cell, which allows users, systems, and resources to be grouped together according to their needs and common interests.
Encouraging others to adopt a new technology is made a lot easier if you have examples of its use. The article on page 16 describes the issues and rationale that led HP to adopt DCE for information technology, and the administration and planning issues associated with this transition.
A typical resources cell can span several systems and networks. To find users, files, devices, and resources inside and outside these cells requires a naming system that allows each cell and the objects contained inside it The have unique names, and a directory service that can cope with different naming systems. One of the an issues surrounding networked systems today is security. How do we protect an open, distributed system from unauthorized access and abuse?
DCE provides a collection of services for developing security mechanisms to protect against unauthorized access. The user's password is the primary key for getting into a system, and in some situations users may be required to enter several passwords during a session to gain access to different applications or other parts of the system.
Each time the opportunity is required to enter another password, the system is made vulnerable to an opportunity for hostile single-step The article on page 34 describes the HP Integrated Login product, which is a single-step login and in which the user enters a password once at login time, and this password is used to grant access system. The security protocol that takes over after the password is entered is described in the DCE security service article on page The article on page 49 describes one of these authorization mechanisms called access control lists ACLs.
ACLs are lists of permissions that belong to certain users or groups of users. However, the interfaces to some of these facilities are quite complex. Transaction processing systems are used in large enterprises to store, retrieve, and manipulate data reliably in the face of concurrent access. One of the even challenges in software development is still testing the product. In the article on page 75 the authors describe how the testing environment for nondistributed, procedural software is not applicable to a distributed environment.
The article describes the evolution of a reusable, object-oriented testing environment called the object testing framework OTF. Bar code readers and magnetic strips are so commonplace today that their usefulness in areas such as banking, manufacturing, and retail is taken for granted. However, these technologies do have their limitations in that they require a direct line of sight and a relatively clean, benign environment.
In today's modern hospitals patients who have to be monitored are connected to an array of high-tech patient hospitals equipment. Aware of the intimidating look of all this equipment, many hospitals are trying to the a more friendly environment in their labor and delivery departments by reducing the amount which de at the patient's bedside.
The HP Series 50 T fetal telemetry system, which is de scribed in the article on page 82, is a step in this direction. The HP Series 50 T combines external and internal fetal monitoring in a lightweight, portable transmitter.

Kong The Distributed Computing Environment DCE is a suite of software that enables networked computers to share data and services efficiently and securely. HP has since released several versions of DCE as a product for HP-UX systems, with added enhancements particularly in tools for administration and application de velopment.
The major technologies in DCE include: A library of routines that enable several paths of execution to exist concurrently within a single process. A facility that extends the procedure call paradigm to a distributed environment by enabling the invocation of a routine to occur on one host and the execution of the routine to occur on another.
A set of services for authentication to verify user identityauthorization to control user access to data and servicesand account management. DCE security services are described in the article on page A service that maintains a data base of objects in a DCE cell and maps their names which are readable by human users to their identifiers and loca tions which are used by programs to access the objects.
CDS is described in the article on page A service that maintains a database of objects that may exist anywhere in the world and enables DCE programs to access objects outside a cell. GDS is also described in the article on page A service that synchronizes clocks on DCE hosts with each other and, optionally, with an external clock.
A service that allows DCE hosts to access each other's files via a consistent global file naming hierarchy in the DCE namespace.
This feature is described in the article on page Integration of DCE application development tools with the SoftBench product and extensions to these tools that sup port tracing and logging of distributed application activity. Unless otherwise specified, these articles describe version 1. Functionality is orga nized and discrete services; clients are users of services and servers are providers of services.
A client program issues requests for services and a server program acts on and re sponds to those requests. A program may play both client and server roles at once by using one service while it pro vides another. For example, in a distributed application that relies on secure communication, both the client and server sides of the application also act as clients of DCE security services.
To make the service abstraction work in practice, clients and servers must agree on how they will interact. They agree on what requests the client can make of the server, and for each request, what data will flow between them. The DCE application development software ensures that client and server programs will adhere to the interface definition. Given an RPC interface definition for a service, an application developer can build and execute clients and servers on different DCE implementations, and the resulting programs will interoperate correctly.
In addition to RFC interfaces for distributed services. In the example of the secure application mentioned above, the application client and the application server will both invoke DCE security routines provided by the DCE run-time library. A cell can encompass one host or many thousands of hosts in a single local network or in an internetwork span ning continents.
The grouping of hosts into a cell does not necessarily follow physical network topology though net work performance characteristics may make some groupings more practical than others. Rather, a cell is usually defined according to administrative boundaries. A cell contains a single security database and a single Cell Directory Service CDS namespace, so all users and applications within a cell are subject to the same administrative authority, and re sources are more easily shared within the cell than between cells.
The minimal set of services in a cell consists of a security server, a CDS server, and some means of synchro nizing time among the hosts. In this cell, the security and CDS databases are replicated for increased performance and reliability, so there are two security servers and two CDS servers. A DCE-based application is installed in the cell in Fig. Threads In a distributed environment the need often arises for one program to communicate concurrently with several others. For example, a server program may handle requests from many clients.BRENNAN'S 1ST HIGH SCHOOL SWIM MEET
The DCE threads facility provides the means to create concurrent threads of execution within a process and hence eases the design and enhances the performance of distributed applications. The threads facility is not itself distributed, but virtually all distributed services in DCE rely on threads, as do most DCE-based applications.
POSK Portable Operating System Interface 1 has defined an industry-standard programming interface for writing multithreaded applications: DCE threads is a user-space implementation of Draft 4 of this specification.
