2016-01-07 18:42:09 +0100 | commented answer | Sage 6.10 not working again on MacOS Just to be clear, you can only move / rename the SageMath folder before you start it for the first time. Once you started sage, you can neither move nor rename it. The "Updating various hardcoded paths" message is incorrect and does not do it. |

2014-11-09 13:12:26 +0100 | answered a question | Virtualbox and Chromium X is launched from /home/sage/.bash_profile, which runs .xinitrc, which starts chromium in kiosk mode. You can change either of them (I would suggest to make a VM snapshot first). Having said that, you'll probably be better off with doing a full Linux installation in a new virtual machine and then compiling Sage yourself. Its easy enough... |

2014-10-03 12:04:12 +0100 | answered a question | The boundary of an implicit_plot3d are jittery. Neat plot! To some extent it is unavoidable, if you have a tube at an odd angle in 3-d then the plot sample points will not line up in the direction of the tube. So no matter how you join the vertices into triangles, it'll always be jagged. If you need visual perfection then you probably have to use tachyon and crank up |

2014-09-21 19:47:00 +0100 | commented answer | Adventures trying to build 6.3 on cygwin Are you using Windows 32 bit? I've fiddled around with it for days until I convinced myself that it'll never work due to address space changes between different runs. Windows 64-bit (even with 32-bit userspace) has a much better chance. On a related note, what is this Windows dominance you are talking about? The accountants and secretaries of the world use Windows, but it has negligible market share in the scientific computing area. If you are serious about computing learn unix asap, you'll thank me later. |
2014-09-21 19:38:44 +0100 | answered a question | What's the best way to access sage from a C program? I would turn it around, instead of controlling Sage from within your C++ program make Sage/IPython your user interface. Then call into your C++ code for whatever you want it to do quickly. Will be a much nicer interface than calling your binary with different arguments. Typically C/C++ code does some fast numerics after you have done some symbolic preprocessing, so usually you don't need to call back into Python then. But you definitely can using the Python C API (tedious), or by linking against Cython module and calling cdef functions, or boost:python. Simple example of a C++ lattice simulation code controlled from the Sage commandline: https://github.com/vbraun/lattice_phi4 |
