21:41 Design #1223 (In Progress): NewPolyRing default indet names

The problem arises in a call to *@Hom_P_Px@* which creates a new polyring by calling *@NewPolyRing@* specifying only ... John Abbott

21:35 Design #1223: NewPolyRing default indet names

The problem was originally communicated to JAA via email. The following is a failing example:... John Abbott

21:32 Design #1223 (Closed): NewPolyRing default indet names

Currently @NewPolyRing@ may be called specifying just the number of indets (but not their names).
Currently the name... John Abbott

09:22 Design #1221 (Closed): Reconsider design for accessing headers and libs of external libraries

The current design for accessing headers of external libs more or less assumes that the external lib has a single hea... John Abbott

07:48 Feature #1219: Frobby version number

With the current design it is trickier than expected.
The main point is that the current design of CoCoALib assume... John Abbott

06:58 Feature #1219 (In Progress): Frobby version number

The Frobby version number (C string) is in @constants::version@ defined in @src/stdinc.h@ and @src/stdinc.cpp@.
Note... John Abbott

06:56 Feature #1219 (In Progress): Frobby version number

It is possible to get the version number from Frobby.
Modify @ExternalLibs.C@ so that it extracts Frobby's version n... John Abbott

18:38 Feature #1218: 32-bit or 64-bit preprocessor macro?

Currently I use the following "trick" to hide code on 32-bit platforms:... John Abbott

18:33 Feature #1218 (Closed): 32-bit or 64-bit preprocessor macro?

To avoid compiler warnings etc. I have used (3 times so far) a CPP trick to "hide" code from 32-bit platforms (which ... John Abbott

18:58 Feature #374: Porting "IdealOfProjectivePoints"

fixed bug: now result is homog Anna Maria Bigatti

18:11 Feature #374 (In Progress): Porting "IdealOfProjectivePoints"

Anna has done the work, but it gives obviously wrong result (not homog).
Here is a failing example:... John Abbott

18:22 Support #1149: Release: CoCoALib-0.99600 (together with CoCoA-5.2.4)

valgrind tests OK!

16:12 Bug #935: ElimMat, ElimHomogMat: complain about zero or negative weights

Decide what we really want for these two functions.
They are mostly OK. Anna Maria Bigatti

16:06 Slug #1105: Primary Decompositon (zero-dim) slow cases

Some things still to do (or consider doing):

15:31 Design #1184 (Resolved): should BeginIter(RingElem) be in SparsePolyIter or in SparsePolyOps-RingElem?

After closing this, I changed my mind:
It is simpler to leave the in @SparsePolyOps-RingElem.C@.
As simple is good,... Anna Maria Bigatti

15:20 Design #1213: Create PolyOps-RingElem?

We should also check whether there are functions in *@SparsePolyOps-RingElem@* which should be moved here.
The mai... John Abbott

15:18 Design #1213 (New): Create PolyOps-RingElem?

Consider creating a new file *@PolyOps-RingElem@* to contain all functions on ringelems which belong to a polyring.
