2021-01-05 17:23:42 +0200 | answered a question | Install Docker image with Python2 Hi, I think the best solution is to fork the dockerfile configuration and modify the part that setups sage. In the git history, earlier revisions should show how 8.9 was built or well, more recent versions might build for python 2 as well. For more detailed support: license and support paragraph |
2018-11-30 15:05:20 +0200 | answered a question | Haskel or Dr.Racket I don't really understand what Racket does and how you want to use it. Can you please describe this at the ticket here: https://github.com/sagemathinc/cocalc... ? There is more than just the langauge and >1000 packages. A better understanding and some context helps us to install software. |

2018-06-27 22:30:59 +0200 | answered a question | Offline vs CoCalc CoCalc is an online web-service, where you can run various interactive documents and other software online. The main additional feature for you as a personal user is collaboration (real-time sharing of what you currently work on) with collaborators. The whole environment is managed for you, backup of your data being taken care of, etc. For example, this can be useful for teaching a class, because you do not have to deal with the specifics of everyone's own computer. The key here is, that SageMath is one of the software utilities which are provided. In particular, it is being taken care of testing that it actually works, plenty of optional packages are installed, and there are also many additional python and R packages in the sagemath environment. There is also a special file called "SageMath Worksheet", which is optimized for working with Sage in CoCalc. SageMath itself doesn't support it. The offline SageMath download version has a couple of differences:
Therefore, that last point might be crucial to answer your question: there are features in cocalc's sagemath, which aren't there out of the box when you download it. But everything that's there you can install yourself. |

2017-09-29 12:21:08 +0200 | answered a question | Keep Sage running in background linux You can solve this by running sage as a webservice. E.g. a simply way is to install flask and instantiate a server, then code an endpoint and send the input there. As long as these commands are stateless, you can even use setup a simple WSGI app and use gunicorn to spawn several sage instances on the backend. |

2016-07-28 14:54:14 +0200 | answered a question | run geogebra in the sagemath cloud Hi, this is a nice idea, but integrating it would not only be highly nontrivial but it is also not "free software" open source. (not sure if it is even open source at all) see https://www.geogebra.org/license made this https://github.com/sagemathinc/smc/is... |

2016-03-28 17:49:52 +0200 | answered a question | Interactive 3d plotting in SageMathCloud Jupyter? hi, those two plotting capabilities are entirely different. one of them is a 3d rendering, which happens based on a triangulated grid and lightning in your browser. the other one is a projected drawing, which has much higher quality but there is no lightning nor such a 3d wireframe. the only middle ground is to use either interacts (in sagews) or ipywidgets (in jupyter) to create control sliders for changing the pan and tilt of the 3d projection of the matplotlib 3d plotting parameters. and personal remark: what exactly do you want to try to plot? I'm not a fan of 3d plots at all and would rather suggest to explore techniques from 2d plotting. maybe that does solve this better, I don't know. |
2016-02-24 13:06:44 +0200 | answered a question | Calling a C function with printf from sage The issue is, that C prints somewhere, where the sagews isn't picking it up. Maybe rewriting print such that it appends to stdout helps? |

Maybe worth to bookmark, since you can also find the PDF documentations there. |

2010-12-06 06:18:30 +0200 | answered a question | Number of Sage Users? no, there is nothing the like. one possible way to get numbers would be to implement a feature that checks if the currently running sage instance is the most recent one and tells the user to update if it is not. then, if the clients send a unique id, one could do statistics with the data. but there is nothing the like going on. so, the best estimate is probably the number of messages on the sage-support mailing list, multiplied with a number of your choice >1 ;) |
