Bug in the Delaunay triangulation with QHull
by Pierre Barbier de Reuille Jan. 15, 2013

Jan. 15, 2013

Hey, I documented a bug in the Delaunay triangulation code here: http://projects.scipy.org/scipy/ticket/1810 The bug can be seen either as a bug in the compilation or in the code and is triggered if there is already a qhull lib compiled for the system, but configured differently. I am not sure if SciPy should use the system lib or the internal one, but it should one or the other consistently, not compile with the internal and link to the system one. I believe this should be easy to fix once a decision has been reached. -- Barbier de Reuille Pierre

ipython sphinx directive in docstrings
by Alexander Arsenovic Jan. 9, 2013

i recently started using the ipython sphinx directive in my docs. it seems to me that using this in the `Examples` section of the docstrings would be good practice, as it prevents me from making error in the examples, and could be used to insert plots. from what i see, the scipy/numpy doc strings dont make use docs use this. is there a reason why *not* to use the ipython directive in scipy/numpy-convention docstrings? alex

PR 397: Getting rid of 2to3 (single codebase for Python 2 & 3)
by Pauli Virtanen Jan. 5, 2013

Jan. 5, 2013

Hi, Prompted by this: http://jakevdp.github.com/blog/2013/01/03/will-scientists-ever-move-to-pyth… here's a conversion of the Scipy code base runnable on Python 2.6 and 3.x without 2to3: https://github.com/scipy/scipy/pull/397 That was fairly easy to do, and I suspect the case is the same for Numpy. But do we want to go this way? On the one hand, this is a cleaner way to go than relying on 2to3 --- which does not convert all semantic differences and can lead to some subtle bugs... On the other hand, well, you have to add list() around map() et al. to make them lists, and have to import xrange, izip et al. from a compatibility module. To me, overall, this doesn't look like a bad route to go. Thoughts? Pauli

Scipy.org is down + question about "topical software"
by Michael Clerx Jan. 2, 2013

Jan. 2, 2013

Dear all, First of all, scipy.org appears to be down and has been for some time today. Yesterday, when it was still up, I registered an account and tried adding a link to the topical software section but got the error "too many links". Does anybody know how/if I can fix this? kind regards, Michael
