THE ULTIMATE Y2K DEFECT
LONDON (June 4, 1998 8:26 p.m. EDT http://www.nando.net) - The oldest
time machine in the world destined to suffer from the millennium bug has
been found in a museum in Liverpool in northwest England, it was
reported Friday.
The 400-year-old instrument, which predicts the position of the planets,
will stop working at the dawn of the new millennium, unable to accept
the date of January 1, 2000, like many unadjusted computers around the
world, museum curators said.
The equatorium, built by an unknown craftsman in 1600, predicts the
position of the Sun, Moon, other planets and even eclipses through a
system of rotating discs and arms. But the last date inscribed was
1999.
"It must have seemed like an eternity at the time," said curator Martin
Suggett.

SIGAda '98 (formerly Tri-Ada): Ada in Context
ACM SIGAda Annual International Conference
OMNI SHOREHAM HOTEL
WASHINGTON, DC, USA, NOVEMBER 8-12, 1998
SPONSORED BY ACM SIGADA,
IN COOPERATION WITH: SIGAPP, SIGBIO, SIGCAS, SIGCSE,
SIGPLAN, SIGSOFT, DC SIGADA, BALTIMORE SIGADA, and ADA-EUROPE.
<http://www.acm.org/sigada/conf/sa98>
The ACM Special Interest Group on Ada (SIGAda) is dedicated to the
technical, business and educational issues related to the Ada
programming language. SIGAda '98, the successor to the annual Tri-Ada
exposition, will be this year's largest Ada-focused conference and is
being organized to attract participants from all segments of the
software engineering community. The SIGAda '98 conference proceedings
will be published as an issue of Ada Letters.
This year we are hoping to increase significantly the participation of
educators and students in the conference, both as authors and conference
registrants.
Ada features a proven track record in large-scale system development and
full support for object orientation, and facilitates writing portable
source programs. Ada's support for sound software engineering is
bringing the language increased attention in computing education and
across a broad range of application areas in government and industry.
Ada's unique ability to interface with software written in other
languages makes it a viable candidate for developing systems in a
multi-language environment. Current Ada projects span a spectrum that
encompasses finance, the Internet, and the Java Virtual Machine,
complementing the language's traditional context of hard real-time,
embedded systems in defense, space, industrial process control, medical
applications, commercial aviation, and ground transportation.
The Conference Theme
We are soliciting conference contributions on the theme "Ada in
Context", pertinent to Ada or of general interest to the Ada community,
from authors inside and outside this community, in industry, government,
research, and education. Topics may include, but are not limited to, Ada
in the context of
* the Internet, the Web, and the National Information Infrastructure
* safety-critical and high-integrity applications
* multilanguage programming (e.g., Ada and Java or C++ in
collaboration)
* defense and non-defense applications
* object technology
* undergraduate, graduate, and secondary-school computing education
* pure and applied research
* software engineering practice
* the spectrum of programming languages and historical trends
* reengineering and maintenance of legacy systems
* making reuse real
* hybrid technology and COTS systems
* process improvement and the Capability Maturity Model
* software quality management
* the tension between better/cheaper/faster and reality
* the tradeoff between short-term gains and long-term quality
EXPERIENCE REPORTS
Experience reports present timely results on the success or failure of
the application of Ada in real-world projects. Such reports will be
selected on the basis of the interest of the experience presented to the
community of Ada practitioners. You are invited to submit a 1-2 page
description of the project and the key points of interest of project
experiences. Descriptions may be published in the final program or
proceedings, but a paper will not be required.
Conference Grants for Educators
As in past years, SIGAda is offering grants to educators to attend the
conference. Grants cover the registration and tutorial fees; travel
funds are not available. More details on the grant program are available

The WebSite Quality Challenge
Edward Miller
ABSTRACT
Because of its possible instant worldwide audience a WebSite's quality
and reliability are crucial. The very special nature of the WWW and
WebSites pose unique software testing challenges. Webmasters, WWW
applications developers, and WebSite quality assurance manages need
tools and methods that can match up to the new needs. Mechanized
testing via special purpose WWW testing software offers the potential to
meet these challenges.
INTRODUCTION
WebSites are something entirely new in the world of software quality!
Within minutes of going live, a WWW application can have many thousands
more users than a conventional, non-WWW application. The immediacy of
the WWW creates an immediate expectation of quality and rapid
application delivery, but the technical complexities of a WebSite and
variances in the browser make testing and quality control more
difficult, and in some ways, more subtle. Automated testing of WebSites
is both an opportunity and a challenge.
DEFINING WEBSITE QUALITY & RELIABILITY
A WebSite is like any piece of software: no single quality measure
applies, and even multiple quality metrics may not apply. Yet,
verifying user-critical impressions of "quality" and "reliability" take
on new importance.
Dimensions of Quality.
There are many dimensions of quality, and each measure will pertain to a
particular WebSite in varying degrees.
Here are some of them:
o TIME:
WebSites change often and rapidly?
How much has a WebSite changed since the last upgrade?
How do you highlight the parts that have changed?
o STRUCTURAL:
How well do all of the parts of the WebSite hold together.
Are all links inside and outside the WebSite working?
Do all of the images work?
Are there parts of the WebSite that are not connected?
o CONTENT:
Does the content of critical pages match what is supposed to be
there?
Do key phrases exist continually in highly-changeable pages?
Do critical pages maintain quality content from version to
version?
What about dynamically generated HTML pages?
o ACCURACY AND CONSISTENCY:
Are today's copies of the pages downloaded the same as
yesterday's? Close enough?
Is the data presented accurate enough? How do you know?
o RESPONSE ITEM AND LATENCY:
Does the WebSite server respond to a browser request within
certain parameters?
In an E-commerce context, how is the end to end response time
after a SUBMIT?
Are there parts of a site that are so slow the user declines to
continue working on it?
o PERFORMANCE:
Is the Browser-Web-WebSite-Web-Browser connection quick enough?
How does the performance vary by time of day, by load and usage?
Is performance adequate for E-commerce applications?
Taking 10 minutes to respond to an E-commerce purchase is
clearly not acceptable!
Impact of Quality.
Quality is in the mind of the user. A poor-quality WebSite, one with
many broken pages and faulty images, with Cgi-Bin error messages, etc.
may cost in poor customer relations, lost corporate image, and even in
lost sales revenue. Very complex WebSites can sometimes overload the
user.
The combination of WebSite complexity and low quality is potentially
lethal. Unhappy users will quickly depart for a different site! And they
won't leave with any good impressions.
WEBSITE ARCHITECTURE
A WebSite can be complex, and that complexity -- which is what provides
the power, of course -- can be an impediment in assuring WebSite
Quality. Add in the possibilities of multiple authors, very-rapid
updates and changes, and the problem compounds.
Here are the major parts of WebSites as seen from a Quality perspective.
Browser.
The browser is the viewer of a WebSite and there are SO many different
browsers and browser options that a well-done WebSite is probably
designed to look good on as many browsers as possible. This imposes a
kind of DE FACTO standard:
The WebSite must use only those constructs that work with the MAJORITY
of browsers. But this still leaves room for a lot of creativity, and a
range of technical difficulties.
Display Technologies.
What you see in your browser is actually composed from many sources:
o HTML.
There are various versions of HTML supported, and the WebSite
ought to be built in a version of HTML that is compatible. And
this should be checkable.
o JAVA, JAVASCRIPT, ACTIVEX.
Obviously JavaScript and Java applets will be part of any
serious WebSite, so the quality process much be able to support
these. On the Windows side, ActiveX controls have to be handled
as well.
o CGI-BIN SCRIPTS.
This is link from a user action (typically, in a FORM in HTML,
but possibly also with Java) back to the application. All of
the types of Cgi-Bin Scripts need to be handled, and tests need
to check "end to end" operation. This kind of a "loop" check is
crucial for E-commerce situations.
o DATABASE ACCESS.
In E-commerce applications either you are building data up or
retrieving data from a database? How does that interaction
perform in real world use?
Some access to information from the database may be appropriate,
depending on the application, but this is typically found by
other means.
o MULTI-MEDIA.
What about streaming video, audio, online chats, and other forms
of WebSite use? How is quality assessed here? What are the
validation mechanisms? How do you know if the presentation is
right?
NAVIGATION.
Users move to and from pages, click on links, click on images
(thumbnails), etc. Navigation in a WebSite often is complex and has to
be quick and error free.
OBJECT MODE.
The display you see changes dynamically; the only constants are the
"objects" that make up the display. These aren't real objects in the OO
sense; but they have to be treated that way. So, the quality test tools
have to be able to handle URL links, forms, tables, anchors, buttons of
all types in a "object like" manner so that validations are independent
of representation.
SERVER RESPONSE.
How fast the WebSite host responds influences whether a user moves on or
continues. Obviously, InterNet loading affects this too, but this
factor is often outside the Webmaster's control. Yet, if a WebSite
becomes very popular -- this can happen overnight! -- loading and tuning
are real issues.
INTERACTION & FEEDBACK.
For passive, content-only sites the only issue is availability, but for
a WebSite that interacts with the user, how fast and how reliability
that interaction is can be a big factor.
CONCURRENT USERS.
Do multiple users interact on a WebSite? Can they get in each others'
way? While WebSites often resemble client/server structures, with
multiple users at multiple locations a WebSite can be much different,
and much more complex, than complex applications.
