- Fitch, Geoff, "The Effects of Ada on Compilation," Defense Electronics, Vol.
- 25, No. 7, June 1993, pp. 48-52.
-
- Mr. Fitch discusses the benefits gained from using incremental compilers.
-
- He says "With traditional compilation, the effort required to integrate the
- change is related not to the size of the change but to the size of the package
- and the system as a whole. With systems of even moderate complexity, work can
- be delayed, affecting large parts of the project."
-
- "An incremental compiler does not treat the package as a whole but examines
- each statement to determine precisely what changes have been made... The
- incremental compiler then performs recompilation, limiting the recompilation
- in other packages to just the places that use the changed statements.
- Although the Ada language standard requires strict ordering of recompilation
- when a change is make, it allows compilers to reduce the compilation cost if
- it can deduce that some of the potentially affected units are not actually
- affected by the change-an allowance that enables incremental compilation to
- take place," says Mr. Fitch.
-
- He concludes that "The important value of incremental technology is that it
- makes the time required to integrate a change proportional to the size of the
- change--not the size of the overall system."

- Endoso, Joyce. "Interview: Ralph Crafts, Ada Maverick; Ada proponent says
- training, not tools, will improve software," Government Computer News, Vol.
- 12, No. 10, May 10, 1993, pp 14, 16.
-
- GCN staff writer Joyce Endoso interviewed Crafts at GCN's offices in Silver
- Spring, Maryland. A synopsis of the published interview follows:
-
- In response to questions about why he disapproved of the DoD's Integrated
- Computer-Aided Software Engineering buy, Mr Crafts said, "If we automate the
- current practices at DoD, we are going to make ourselves more efficient at
- doing bad things... Give me a team of skilled software engineers with
- primitive tools, and I will out perform any other team that has access to very
- powerful tools. The problem with DoD is that we constantly default to try to
- use technology as the solution. Technology is not the problem."
-
- Regarding questions about the availability of software engineering at defense
- universities, he expressed his concern that a software engineering program
- does not now exist. He said, that because there are not any minimum
- requirements for education or any form of certification process, "Literally
- anybody in this country can hang up a shingle and be a programmer."
-
- In his final statements, he said, "If we don't have a national priority that's
- oriented toward improving software engineering, from the education to the
- knowledge of the managers and the procurement people, we are going to be a
- less than first-rate economic power by the turn of the century. I believe
- that software engineering and skilled software engineers are the two most
- important facets in preventing that from happening. If you can show me, based
- on good engineering criteria, that there's a better language than Ada, I will
- pack up my tent and go home and you can use that language."

- Barnes, John, "Object-oriented Programming; Ada 9X Offers Flexibility &
- Reliability," Alsys World Dialogue, Vol. 7, No. 1, Spring 1993, pp. 4, 5.
-
- Mr. Barnes discusses how Ada9x features enhance Ada's object-oriented
- programming capabilities.
-
- He says, "the object-oriented properties of Ada 9X offer many important
- advantages such as type extensions, class-wide programming, and dynamic
- dispatching. As a consequence, a system can be extended reliably without
- having to disturb and recompile existing proven parts."

- Endoso, Joyce, "Ada Gets Credit for F-22's Software Success," Government
- Computer News, Vol. 12, No. 9, April 26, 1993, p. 6.
-
- "Much of the credit for the software integration success of the Air Force's
- F-22 program goes to Ada," said Lt. Gen. Albert Edmonds, the Joint Staff's
- acting director for command, control, communications and computer systems.
-
- He cautioned that Ada is not a panacea, but praised the inherent disciplined
- approach to developing software that Ada provides and said that "nothing can
- compare with its [Ada's] ability to integrate different efforts."
-
- Lt. Gen. Edmonds, who sets C4 systems policy for the Defense Department, spoke
- at the DoD Annual Software Technology Conference held at Salt Lake City, Utah.

- Jenks, Andrew, "Alsys Group Still Banks on Ada Computer Language," Washington
- Technology, Vol. 8, No. 3, April 22, 1993.
-
- The Alsys Group has moved its worldwide headquarters from France to Reston,
- Virginia. Alsys recently acquired Telesoft, which ran most of its worldwide
- business from offices in San Diego, California. Together the two firms made
- $43 million in revenues for 1992 and will have a combined staff of about 280.
- About 30 people will be located at the firm's Washington area headquarters.
- Sixty percent of the firm's business and development occurs in the United
- States.
-
- Pentagon users have balked at the idea of using Ada for routine data
- processing applications
-
- Ada efforts are focused in the former U.S. Alsys headquarters in Burlington,
- Mass. CASE development is centered in the former TeleSoft headquarters in San
- Diego.
-
- Alsys claims a 50 percent share of Ada software development products for the
- UNIX operating system that dominates the technical and federal markets. About
- half of the firm's business comes from defense and the other half from the
- aerospace, transportation, and automotive industries.
-
- Jean-Louis Olie, CEO of the Alsys Group believes that the implementation of
- Ada 9X, which adds object-oriented capabilities, will put Ada more on a par
- with arch competitor C++.
-
- Menke, Susan M., "Defense Users, executives Want to Know Where Ada Effort
- Stands," Government Computer News, Volume 12, No. 7, March 29, 1993, p. 3.
-
- "We need to stop the language free-for-all and make an unbiased analysis of
- DoD needs. Put the Ada controversy to bed and clearly articulate what the
- demand for Ada products is," said Lt. Gen. Peter A. Kind, director of
- information systems for command, control, communications and computers.
-
- General Kind, who spoke at the 11th National Conference on Ada Technology,
- Williamsburg, Virginia, said "We're not going to make a huge change overnight,
- as I see it. We're hearing calls to abandon Ada from DoD officials. I'm
- asking contractors to assess it, and they say it does what's needed but they
- can't get enough qualified programmers."
-
- "Meanwhile Ada reuse efforts are building momentum," Rear Adm. Robert M. Moore
- told the conference. "Moore, commander of the Naval Information Systems
- Management Center, said the service is about to publish its software reuse
- implementation plans."
-
- "Customers are eager for the promised savings from reuse, according to Marrea
- Riggs, director of the Army reuse center in Falls Church, Virginia."
-
- "Bob Rutherford, senior engineer at the Air Force Defense Software Repository
- at Maxwell Air Force Base, Alabama, said 'actual avoidance of costs' from four
- reuses of an Ada Posix binding would amount to $15.8 million."
