I have a candidate (master's) degree in mathematics from the university of Copenhagen (minor in computer science) from 2003, I haven't done much math since. My thesis was in complex analysis.

How to provide untrusted users access to download data from a Linux server with rsync? You should probably add a description of what "semi-trusted" means. It affects the options quite a lot. |

I have 12 of these bags of LEGO and have no idea what set they go to LEGO is not a noun, so please don't use it as one. |

Traffic issues from LXC containers with ufw configuration provided by Ansible I neither know ansible nor ufw, but I have struggled with getting network to my local lxc guests. But as you can configure networking in LXC in several ways (bridging, direct access to the LAN, ...) and haven't said how you do it, makes it impossible for us to guess what is wrong. |

Integer solutions of $x^3 + y^3 +xy=25$ For some basic information about writing mathematics at this site see, e.g., basic help on mathjax notation, mathjax tutorial and quick reference, main meta site math tutorial and equation editing how-to. |

The number of ways of picking $5$ increasing or equal numbers $0$ to $5$ $30 \choose 5$ is too many, it includes things such as $4, 2, 3, 1, 1$. My first thought was to draw a square and find a way through it, but already before I had formalised that in my head I realised what @lulu says. |

How can the length of a right angled triangle be equal to $0$? What you're talking about is not the length of the triangle, but the length of it's hypotenuse. (and as @Andre has said you need to consider the length of the side along the imaginary axis). |

Function where $f(x)=1$ when $x$ is an integer, and $f(x)=0$ everywhere else @TheOtherTerry: I meant the absolute value (which is what the OP uses). But I've deleted the comment as it lead nowhere. |

Trouble installing software through terminal on Debian "possibly worse" was just meant to say that I hadn't checked which options were set by none and not the other, and in some cases it comes down to personal preference if you find a given option to be good. |

Trouble installing software through terminal on Debian Why did you add a different repo for wine, when you could install it from Debian's own repos? In general it's not recommended to add repos to a Debian. |

Trouble installing software through terminal on Debianapt-cache search is just an old (and possibly worse) form for apt search. They search in the same "database" , but as the man-page for apt says: "enables some options better suited for interactive usage by default compared to more specialized APT tools like apt-get(8) and apt-cache(8)".

Can I bring a cardboard box full of books as my checked-in baggage with Ryanair? A box of those dimensions filled with books weighs a lot more than 23kg, so it's a little confusing that you both talk about filling it and about staying under the weight limit. |

Contact between an edge and surface Why do you think there obviously is an area of contact? Does the "line" you're thinking of actually have a thickness? |

preventing anyone from reading /etc/passwd and /etc/group/etc/shadow was introduced to prevent anyone from seeing the encrypted password of everyone else, because many things would stop working if permissions on /etc/passwd were tightened. But that is many years ago (but I'm old), and I don't know if it would work today.
