Ada Magica

Diese Seite auf Deutsch.

From 1997 to 2007, Ada Magica was my column in Softwaretechnik-Trends, the periodical of Ada Germany, the special interest group 2.1.5 Ada of the German Informatics Society (GI). It was dedicated to Ada's not so well-known sides. Since this is a German group, articles appeared in German.

This is a list of articles that appeared in the Softwaretechnik-Trends (SWTT), which I translated into English.

• May out-parameters be read? (Ada83) - SWTT 17.1 (February 1997)

This is essentially an Ada83 specific problem, but since the old standard is still heavily in use and also some basic coding styles are discussed (that are valuable for Ada95 as well), I deem this problem worth publishing.

• An Invitation to Lady Ada's - SWTT 17.2 (May 1997)

A case of unexpected ambiguity

• Revenge (for Lady Ada's invitation) - SWTT 18.1 (February 1998)

Representation clauses und two's complement

• Secretiveness - SWTT 20.1 (February 2000)

Too much hidden?

• Lady Ada's 20th birthday

Ode to Lady Ada on her 20^th/185^th anniversary, first published in SWTT 18.4 (November 1998) in German on account of her 18^th anniversary.

The date of first standardization and the standard's number are no coincidence.
