16:38 CoCoALib Feature #651: Optimized algorithms for implicitization (slicing algorithm, elim, subalgebra..): I'm running tests with the profiler on our linux virtual machine.
One surprise was that the profiler gave a mysterio... Anna Maria Bigatti

23:02 CoCoALib Feature #651: Optimized algorithms for implicitization (slicing algorithm, elim, subalgebra..): One problem with @ImpliciDirectWithCond@ is that the normal form computations take too long. Here is an idea which _... John Abbott
16:22 CoCoALib Feature #437: MemPool: order free blocks?: It seems the correct (portable) way to sort a @vector<void*>@ is to use @sort(v.begin(), v.end(), std::less)@.
Apa... John Abbott

22:40 CoCoA-5 Feature #652 (In Progress): Flag to enable/disable printing of list of loaded packages: I have modified @Main.C@ but not checked in -- will discuss with Anna first.
* replaced @bool printPremable@ by @int... John Abbott

15:39 CoCoA-5 Feature #653: Emacs UI: use "warning colour" for an unmatched */: I agree, it would be nice.
But I have no idea how to achieve it :-( Anna Maria Bigatti
15:22 CoCoA-5 Feature #653: Emacs UI: use "warning colour" for an unmatched */: Not very important --> low priority.
Not sure how easy this might be; given the low importance, I'd say it's worth d... John Abbott
15:20 CoCoA-5 Feature #653 (New): Emacs UI: use "warning colour" for an unmatched */: It may be helpful to have the emacs UI use a visible "warning colour" for an unmatched @*/@ comment end marker.

11:40 CoCoA-5 Feature #652: Flag to enable/disable printing of list of loaded packages: Anna points out that there is already a similar flag (@--no-preamble@) which is used when running the CoCoA-5 tests (... John Abbott
11:15 CoCoA-5 Feature #652: Flag to enable/disable printing of list of loaded packages: I have made this change:
the list of packages loaded at the start are printed into @ostringstream PkgOut@ (in Main.C... Anna Maria Bigatti
11:06 CoCoA-5 Feature #652 (Closed): Flag to enable/disable printing of list of loaded packages: Add a command-line flag to enable printing of package names as they are loaded. Currently the names are always print... John Abbott

11:30 CoCoALib Feature #651: Optimized algorithms for implicitization (slicing algorithm, elim, subalgebra..): The very latest version of @ImplicitByPoints3@ does occasionally go a little faster than @ImplicitDirectLPP2@, but it... John Abbott

16:04 CoCoALib Design #649: Make SmallFpImpl safer to use: I've just wasted a good hour trying to figure out why my new code was about 10% slower than the old code.
The reason... John Abbott
