- 20:59 CoCoALib Feature #24: object files collected in one directory
- Right now I do not recall why we think it is a good idea to have all object files in a single directory.
Pro:

- 20:46 CoCoALib Feature #664: Impl small non-prime finite fields (using logs)
- When char=2 we can readily use (binary) integers to represent field elements.
The idea is to find a generator @theta... - 20:41 CoCoALib Feature #665: Integrate Janet/Pommaret basis code
- Mario will try to put all his source code in his own namespace (perhaps called @involutive@), and will put all his fi...

- 10:33 CoCoALib Feature #651: Optimized algorithms for implicitization (slicing algorithm, elim, subalgebra..)
- I changed all ring names into Kt and Kx in TmpImplicit.C

- 17:42 CoCoALib Feature #665 (In Progress): Integrate Janet/Pommaret basis code
- Integrating Janet/Pommaret basis into CoCoALib and CoCoA-5
What Mario will do:

- Impl small non-prime finite fields (?using log/exp tables?)
Werner+Mario would like these ASAP; especially with ch...

- 13:19 CoCoA-5 Bug #663 (New): Emacs UI: C-c C-\ copies line cursor is on
- The emacs key sequence @C-c C-\@ quits a running CoCoA-5 (same as Signals->QUIT).
I noticed that if the cursor is no...

- 14:11 CoCoA-5 Feature #659: Ring ID: separate index values for "system created rings"?
- The command @RationalSolve@ seems to burn through lots of rings, so if called many times, can burn through very many ...
- 13:50 CoCoALib Feature #661: Laurent polynomials
- There are two cases to consider:
* dense univariate
* sparse multivariate
One "easy" solution is to use existing da... - 13:48 CoCoALib Feature #661 (New): Laurent polynomials
- I propose adding a @LaurentPolynomial@ ring extension.

- Should we have a function which says which indets actually appear in a polynomial?
- 19:04 CoCoA-5 Feature #659: Ring ID: separate index values for "system created rings"?
- Not sure it's worth the hassle.
It would be prettier, but I think we are the only two who would appreciate it ;-)
- 16:02 CoCoA-5 Feature #659: Ring ID: separate index values for "system created rings"?
- Maybe this should be in CoCoALib?
If we do decide to do this then I think there would have to be a distinct way of... - 15:58 CoCoA-5 Feature #659 (New): Ring ID: separate index values for "system created rings"?
- In a recent CoCoA session I found I was using a ring with ID value almost 60000 -- no idea why it was so high. I cer...
- 17:11 CoCoA-5 Bug #660: Emacs UI: endfunc does not indent the line
- It works fine for me (and my cocoa5.el is cvs'ed).
Maybe you should check you are not including an older cocoa5.el?
- 16:11 CoCoA-5 Bug #660 (New): Emacs UI: endfunc does not indent the line
- When I use @C-c C-e@ to add the relevant end-keyword it usually automatically indents the line; the indenting does no...

- 20:30 CoCoA-5 Feature #657 (New): use command, ring syntax, RingOf
- Is it desirable to be able to issue a command such as this?
@use RingOf(M);@
Note that this has potential implica... - 20:25 CoCoA-5 Design #656: eval: in which ring should the result be?
- We could make obsolescent the version which wants coords in the poly ring -- so it still works but produces a warning...
- 20:24 CoCoA-5 Design #656: eval: in which ring should the result be?
- Currently @eval@ is written in CoCoA-5, and just checks args before calling @subst@.
I find the version which retu... - 20:19 CoCoA-5 Design #656 (New): eval: in which ring should the result be?
- Currently @eval(f,[xval,yval])@ wants @xval@ and @yval@ to be in the same ring as @f@; and the result is then natural...

- 17:10 CoCoA-5 Slug #655 (New): MakeSet can be very slow
- @MakeSet@ can be very slow on long lists where most of the elements are distinct.
Find a way to make it faster. - 17:08 CoCoA-5 Support #654: Rename adjoint to adjugate???

Possible new names as @ClassicalAdjoint@ or @adjugate@; I suppose the... - 17:06 CoCoA-5 Support #654: Rename adjoint to adjugate???
