- 11:26 Bug #650: CoCoA-5 test (SourceAnna); problem in HilbertPoly
- I have already reported by phone that there is a problem (with @SourceAnna@) on 32-bit Linux.
On my 64-bit MacOSX ... - 11:22 Bug #650 (Closed): CoCoA-5 test (SourceAnna); problem in HilbertPoly
- Sometimes the CoCoA-5 test @SourceAnna@ fails (on 64-bit MacOSX).
The problem appears when executing the line:

- 16:42 Design #646: Unique copies of free modules?
- I propose putting all the technical discussion in #647, a parallel issue to this one (since practically all the real ...
- 16:33 Design #646 (New): Unique copies of free modules?
- A recent bug report from Oneto suggests that it is surprising/unnatural that @NewFreeModule@ should create distinct (...

- 22:23 Design #637 (In Progress): Undesirable consequence of automatic mapping of RingElems?
- I think the values of @deg(A)@ and @deg(B)@ are well defined.
If we have @not(deg(A) = deg(B))@ then it would be q... - 22:12 Design #637 (Closed): Undesirable consequence of automatic mapping of RingElems?
- Suppose we allow automatic mapping of ringelems into superrings.
Consider the following scenario:... - 22:05 Design #636: Distinguish indets from symbols in coeffring in Use command
- Consider the following scenario:...
- 18:42 Design #636 (Rejected): Distinguish indets from symbols in coeffring in Use command
- The @use@ command assigns the top-level variables whose names match those of the symbols in the ring. The assigned v...
- 18:37 Design #635: Automatic mapping of RingElem (in operation with a compound value)
- At the moment the idea of automatically "mapping down" ring elements makes me feel uneasy (perhaps solely because I h...
- 12:57 Design #635: Automatic mapping of RingElem (in operation with a compound value)
- The description says it all, but I prefer phrase it also like this:...
- 12:32 Design #635 (In Progress): Automatic mapping of RingElem (in operation with a compound value)
- I note that this proposal would still produce an error if one tries to compute:...
- 12:21 Support #548: Printing rings with ID
- I think it has just been forgotten; it seems like a good idea to me. Indeed now that direct printing produces a very...

- Robbiano's scenario was the following... a bit simplified:...
- 20:07 Design #635 (Closed): Automatic mapping of RingElem (in operation with a compound value)
- If we decide to allow automatic mapping of @RingElem@ values, Anna suggests that only simple/single values can be aut...
- 20:02 Design #634 (Rejected): Symbol in the coeff ring
- My previous comment convinces me that it is not feasible to make @a@ have the value of the symbol @a@ in the smallest...
- 18:35 Design #634: Symbol in the coeff ring
- There is a potential problem with my suggestion of symbols being mapped into the smallest containing subring. In the...
- 16:11 Design #634: Symbol in the coeff ring
- The problem was highlighted when Robbiano wanted to multiply a matrix (over @K@) by @a@; CoCoA-5 gave a _mixed rings_...

- Consider the following mini-session...
