- 18:15 Design #1346: C++14: use the new for loop syntax where appropriate (like cocoa's foreach)
- I have changed some @for@ loops to use the new syntax.
It is slightly worrying that one can change the code so easil... - 16:14 Feature #1419 (New): DynamicBitset::IamAll1s
- A challenge for Anna: can you write @DynamicBitSet::IamAll1s@ using the new "range-based" for loop syntax?
- 12:29 Feature #1395: SHA checksum for released code
- My idea in comment 8 is not so clever... well, the SHA cannot be inside the TGZ file.
Just put it on the website in ...

- 23:44 Bug #1264 (Feedback): Remove unnecessary files before making CoCoALib release TGZ files
- I have now added the related issue (#990) for the targz file for the binary release.
I suppose we should do a fina... - 15:13 Slug #1375: Radical 0-dim: varied timings

Make the same change there???
- 10:42 Feature #1395: SHA checksum for released code
- -A fairly simple approach would be to put the SHA checksum in the release notes- (perhaps near the start?) *<--- BAD...

- 16:10 Feature #1417: RadicalZeroDim with extra parameter for GBasis timeout
- This is related but not quite the same as #1378.
The point is this: if we let more time to compute the partial GBase... - 16:05 Feature #1417 (In Progress): RadicalZeroDim with extra parameter for GBasis timeout
- We have seen how changing the timeout for GBasis can affect the time dramatically.
Should we make a function @Radica... - 15:38 Slug #1375: Radical 0-dim: varied timings

Currently there is "variable bound" + "fixed ... - 14:01 Design #1391 (Resolved): RingElems: syntax with [ and ] ?
- Made it more robust with empty list.
- 13:26 Feature #91: Return type & name for "indets" of a PP
- The name is now *@IndetsIn@* the same name for the analogous fn for @RingElem@.
- 11:01 Bug #1264: Remove unnecessary files before making CoCoALib release TGZ files
- Anna tried her script for making a source code TGZ file. We found just 3 spurious files: these have been removed.
I... - 10:58 Design #1409 (Closed): myTestIsPrimary & Co. : fix design

There is a fn called *@indets@* which returns a @vector<long>@ being a list ... - 16:21 Design #1346: C++14: use the new for loop syntax where appropriate (like cocoa's foreach)
- I looked for @iterator@ and changed in a few more files. (can't remember which)
Not so many left to do. - 15:09 Feature #658 (Closed): Indets actually in a poly (or vector or matrix)
- Implemented *@IndetsProd@* -- advantage is that it gives same interface in CoCoALib as in CoCoA-5. *@IndetsIn@* is a...
- 14:24 Feature #658: Indets actually in a poly (or vector or matrix)
- After discussing with Anna, she wants the result to be a polynomial (which is a 1-monomial) whose value is the produc...
- 14:08 Feature #1395: SHA checksum for released code
- Anna confirms that she has @shasum@ on her computer.
The main question remaining is how to use the SHA sum in a se... - 11:12 Support #26: Redmine Administration

*NOTE* the help will almost certainly change when #1360 is i... - 10:55 Support #1338 (In Progress): Release CoCoALib-0.99700
- 10:30 Bug #935 (Closed): ElimMat, ElimHomogMat: complain about zero or negative weights
- The code calls @IsNonNegGrading@ (see @MatrixForOrdering.C@ around lines 959 and 973).
I presume @IsNonNegGrading@ ... - 10:09 Feature #958: New function: multiplicity and dim
- Yet to be fixed: non homogeneous input.

- I have added a test to @test-matrix2.C@.
- 15:17 Feature #1277 (Feedback): Gaussian row reduction

Do we really need a test?
