It was being done for the TeX site regularly by Paulo Cereda: https://bitbucket.org/cereda/tex.sx-data-dump . |
2014-09-01 15:50:43 +0200 | commented question | integrate(sin(x),x) doesn't work @rws: Please do not downvote questions, especially those from newbies. While I agree that the question lacks the most important detail, we should be a welcoming community. Asking for this information as @tmonteil has rightly done is the way. If we get no response after a couple of months, we could close the question as being too localised. |

2014-08-23 21:43:17 +0200 | commented answer | How to find Smith normal form of a matrix over regular rings? In fact, the error is misleading: it should say that the Smith form makes sense only over Principal ideal rings which are domains (I wrote it like that for emphasis: of course, I mean the Principal Ideal Domains). There is a similar structure theorem for modules over Dedekind domains, but now the torsion-free = projective which is free + fractional ideal. This probably is not implemented. At any rate, this is not Smith normal form (probably, this must be called the Steinitz normal form...). |

2014-08-23 21:27:21 +0200 | answered a question | Create/Modify SageMathCloud Project to be Private A SageMathCloud project is by default private: that is, the files you create inside the project is available only to you and the cloud server hosting those files. On the other hand, if you would like to share all the files in a project with someone who has an account on SageMathCloud, you may do so by adding them to the Collaborators list available from the Settings (wrench icon). You may search for your collaborator by using their email address or the SMC username. |

2012-11-28 03:45:52 +0200 | marked best answer | Rolling back patches I did this for years. You are right that it's not well documented. will roll back the previous commit, and will revert the changes of that one commit. Otherwise you'll have to find out what commit to revert to with to see how to use that command. It says it's not what you're looking for, but it is, in a brutish sense. You're right that queues are easier in the long run, but there is a definite learning curve. The (eventual, not soon) switch to git probably won't make things any easier, just different. |

The documentation does not seem to answer this question. I'd appreciate your help. Come to think of it, I could have taken the Hg Queues route, much simpler to maintain, IMHO. sigh Thank you. |
