[sage-devel] A new book on Sage, for high school students in Poland
Hello, I'd like to mention a new book using Sage I co-authored, that got released last week. It is in Polish and covers all mathematics topics from high school, according to the current core curriculum in Poland. It is not a textbook, but supplemental material, which aims to wake up the imagination on the way to proper understanding of mathematics topics. This is why decided to use mathematical package to remove the burden of calculations, and this is why we also decided to use lot of references to pop-culture and imagined stories - sea snake named Ssstefan approaching the Viking ship helps to understand function transformations, Brian the crocodile tamer helps to see overlapping intervals. We covered all major interfaces (Cell, Cloud, Notebook, iPhone, Android apps). It is 352 pages, typeset using PDFLaTeX+SageTeX package (we had to adjust it a bit, because we decided to save images in SVG and then convert to TikZ using https://github.com/kjellmf/svg2tikz - for 3D graphics we decided to output png from Tachyon and then added overlay in TikZ, which was more tricky, but also worked). It would be cool if our book could be mentioned on http://www.sagemath.org/library-publications.html#books - and it would be also very helpful if we could hear some opinions. Especially, that we have some plans on making an English version in the future - and any opportunity to improve would be great (we need to find some budget for professional translation service, as there are jokes and ideas in the book that do not translate 1-1). Below are some release informations: Authors: Andrzej Giniewicz, Katarzyna Zajączkowska Title: "Zrozumieć matematykę z pakietem Sage" (translation: "Understand mathematics with the Sage package") Publisher: GiS (http://www.gis.wroc.pl/) ISBN: 978-83-62780-42-6 Year: 2015 Web page: http://www.eurekacode.com/matematyka Sorry, but web pages are in Polish.

[sage-devel] numpy/matplotlib/scipy upgrade needs review
Hi all, I have put three tickets that have to be merged together as needing review. * numpy 1.10.1 http://trac.sagemath.org/ticket/17642 * matplotlib 1.5.0 http://trac.sagemath.org/ticket/19556 * scipy 0.16.1 http://trac.sagemath.org/ticket/17643 numpy has three patches added. The first two are backport provided by upstream and included by some distro. The last one is to enable sage to interact nicely with linspace from numpy. After a good discussion with upstream we have agreed to the fix which I included. Before my changes are merged in upstream numpy I need to write some tests (help welcome). The upgrade of numpy generate a lot of deprecation warnings. All but two of them go away by upgrading matplotlib to 1.5.0. The ticket for the matplotlib upgrade also has fix for the last two deprecation warnings. Finally the matplotlib upgrade obsoletes a doctest that was showcasing a limitation that doesn't exist anymore. Said doctest has been removed. Finally the upgrade to numpy also change the output (format) of one doctest involving scipy. Upgrading scipy changes the format of that doctest again so I only fixed it in the scipy ticket upgrade.

[sage-devel] Patchbot warnings about "increased startup time"
Hello everybody, Once in a while one of my tickets is flagged by the patchbot as "increasing startup time". Sometimes I add a function or two and thus wonder if I did something wrong, but in this specific case I am relatively confident that I didn't do anything that might have increased startup time: Could somebody who knows about such matters see why the patchbot reports this ticket as impacting Sage's startup time? http://trac.sagemath.org/ticket/19564 All it does is remove some pointers from a C++ file.

Do you think that Sage should check that all packages are installed before starting? I don't think we should do that: imagine that for some reason R does not build on a particular system. That user might be happily using Sage without R installed. Also, Sage itself is used by certain pieces of the build system (conway_polynomials for example uses Sage to install a pickle). > and/or you can't write to HOME/.sage Well, that's a different thing entirely. If no error message shows up, this is indeed a problem with the build scripts. I had reissued make and the build completed, including building documentation! Or so it said, anyway. It never noticed the missing packages. I don't get it. You said you *interrupted* the build. Bizarrely, doing "sudo make" so it could write to my local folder FIRST rebuilt the documentation (quick because no changes) and THEN just now started building cddlib, gfan, cvxopt, and a host of other stuff. I will repeat that there were no relevant error messages in the log files. Yes, this order is optimized for parallel builds. With parallel builds, you want to start building the documentation as soon as possible since it takes a long time.

[sage-devel] Re: errno 2 on server only due to missing jmol files
Okay, I think that I figured out the problem. I built Sage from scratch to upgrade our notebook server, and find a whole slew of packages that never built! But there are no error messages I can find - just no log files. In particular, I can't find any jmol - or indeed cddlib or some other stuff. But that would explain my initial problem. How could that happen? I believe there is an error in our build scripts. If the build is interrupted (as was the case here) and/or you can't write to HOME/.sage, bad things will happen without errors. I had reissued make and the build completed, including building documentation! Or so it said, anyway. It never noticed the missing packages. Bizarrely, doing "sudo make" so it could write to my local folder FIRST rebuilt the documentation (quick because no changes) and THEN just now started building cddlib, gfan, cvxopt, and a host of other stuff. I will repeat that there were no relevant error messages in the log files. I am 90% certain that my problem will be solved by the time all these packages finish building, but I wanted to bring this up because perhaps others will be building Sage remotely and not use/not remember how to use/not know how to use things like screen and nohup. At the very least make should figure out that these packages aren't built! - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
