Open Source Mathematical Software

| Increasingly, proprietary software and the algorithms used are an essential
| part of mathematical proofs. To quote J. Neubüser, 'with this situation two
| of the most basic rules of conduct in mathematics are violated: In
| mathematics information is passed on free of charge and everything is laid
| open for checking.'

[OOXML] Mathematically Incorrect
,----[ Quote ]
| So when it comes to comparing MSOOXML and ODF v1.0 on the basis of the
| inclusion of "Formula Definitions", it becomes clear that the anti-ODF folk
| have not much to shout about. In fact MSOOXML's "Formula Definition" is
| deficient and inaccurate.

OOXML: The Formula for Failure
,----[ Quote ]
| As I've shown, in the rush to write a 6,000 page standard in less than a
| year, Ecma dropped the ball. OOXML's spreadsheet formula is worse than
| missing. It has incorrect formulas that, if implemented according to the
| standard may cause loss of life, property and capital. This standard is
| seriously messed up. And shame on all those who praised and continue to
| praise the OOXML formula specification without actually reading it.
