18:08 CoCoA-5 Bug #1234 (In Progress): CoCoA should read unicode: It seems that cocoa can only read ascii... Anna Maria Bigatti

16:18 CoCoA-5 Feature #1231: system command: I am now thinking that making *@system@* a new interpreter command was not a clever idea. It can simply be a built-i... John Abbott

17:20 CoCoALib Bug #1233 (Resolved): factor SEGV -- too large characteristic: I have found two bugs related to the old code in the factorizer which uses @int@ (for speed?) rather than @long@.
I ... John Abbott

14:58 CoCoA-5 Feature #1231 (In Progress): system command: I have made a first attempt at implementing a "system call" function, but I am not really comprehending the structure... John Abbott

09:58 CoCoALib Bug #1233: factor SEGV -- too large characteristic: Obviously I discovered the bug while demoing CoCoA-5 :-/
Ange would like to be able to factorize (univariate poly... John Abbott
09:57 CoCoALib Bug #1233 (Resolved): factor SEGV -- too large characteristic: @factor@ can cause a SEGV if the characteristic is @NextProbPrime(2^31)@.... John Abbott

18:03 CoCoALib Feature #898: New function: cardinality of finite field?: I have just noticed that *@LogCardinality@* is not implemented as I expected: it returns 0 when applied to a poly rin... John Abbott

17:52 CoCoALib Design #1232 (Closed): IsPrime(0): Indeed, I probably created @IsFiniteField@ exactly for this reason. Also the correct code is clearer to read:... John Abbott
15:51 CoCoALib Design #1232: IsPrime(0): I'd rather keep the error, as in this case you already have @IsFiniteField@.
I'm not sure whether one would expect i... Anna Maria Bigatti
10:44 CoCoALib Design #1232 (Closed): IsPrime(0): What should *@IsPrime(0)@* do?
Currently it gives error (because arg must be strictly positive).
I ask because ... John Abbott

18:41 CoCoA-5 Feature #1231: system command: I believe that Macaulay and Singular have such a command, and they use it for their interfaces.
So I do agree that w... Anna Maria Bigatti
16:04 CoCoA-5 Feature #1231 (Closed): system command: CoCoA-4 had a *@system@* command which would pass its string argument to a shell for execution.
There is no such c... John Abbott
15:59 CoCoA-5 Bug #724: RationalSolve: wrongly complains about non zero-dim even in finite char: The example from #723 still fails with the following error:... John Abbott
