- 13:57 Feature #876 (New): subst: allowed also for indets in the coeff ring
- Suppose we have a poly ring of the form @QQ(a,b)[x,y]@ and I want to substitute @b=a+1@.
Currently @subst@ refuses b...

- 14:00 Slug #875 (In Progress): Interpreter is too slow reading a big polynomial
- I'm trying to read a large polynomial: about 6Mbytes, about 127000 terms in 100 indets, coefficients in @QQ@ (but all...

- 19:05 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset()
- I have added a new CoCoALib test (@test-bug6.C@) which tests for this specific problem.
It should later be expande... - 08:57 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset()

Even though I'm hoping for a proper re... - 13:38 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset()
- I continue to think that the current design of ideals is completely wrong (but I cannot find the redmine task about t...

- 09:35 Bug #870: GBasis of product of ideals is wrong (Vadim Tropashko) --> I.myReset()

- It is also the case for @bin@.
In CoCoALib they are called @deriv@ and @binomial@, so the lower-case name is differe...

- 20:06 Bug #287: --fullCoCoALibError prints too much (Try/UponError)
- I still like my proposal in comment 2. How easy it will be to implement is not clear to me.
Anyway the implementa... - 20:00 Design #868: Der, Bin: why the capital letter?
- I understand we want to keep @Der@ for backward compatibility.
Since we have @deg@, @den@, @det@ why not also @der... - 19:59 Design #868 (Closed): Der, Bin: why the capital letter?
- In CoCoA-5 the function for computing formal derivatives is @Der@; why does @der@ not exist?

This means that users computing...
