Kahn to Resign as Borland Chairman: Philippe Kahn, a French programmer who started Borland International Inc. in 1983 and saw the software company rise close to prominence and then fall markedly, will resign as chairman at the start of next year, the company said. Kahn, 43, resigned as chief executive in January to concentrate on Starfish Software, which he started last year. He will remain on the board of Borland, which is based in Scotts Valley, Calif. The company was once a leading seller of database programs for personal computers. After being squeezed by competition and several investment missteps, Borland last year sold its mass market products to concentrate on programs that help other software creators write programs. The company’s annual revenue for the fiscal year that ended in March was $254 million, down from $393 million a year earlier.
