@JohnDoea , I saw the proposed edit before the change to the question and it seemed to make the answer worse rather than better. I can apply the changes again though, fixing the typo. (more) |

A: Running remote scripts (cloud scripts) locally --- valid and securely as possible > An example for a current problem; the file downloaded can have a trivial name such as install.sh and collide with similar files (the rm is especially problematic here I think). This is why `tempfile` exists. FILENAME=`tempfile` cd DESTINATION && wget -O ${FILENAME} https://raw.g... (more) |

`while(arr[index++] != 0);` does *not* accomplish the same thing, because it increments `index` one more time than `while(arr[index] != 0) index++;` (more) |

A: Update list based on presence of identifier in a second list This can't be done with the standard library. It's quite common for people who want to do this to define their own extension method public static void Foreach(this IEnumerable items, Action action) { foreach (var item in items) action(item); } which would allow the one-li...

@elgonzo, that's pretty much what I suspected. For my immediate purposes it's not strictly necessary to use an interface, but using an abstract class instead eliminates some interesting future directions. E.g. an orderable subtype and a field subtype couldn't be combined to an orderable field subtype... (more) |

| Question | — |
F-bounded polymorphism, interface operators, and type inference in C# C# language version 8.0 introduces limited support for static methods, operators, etc. in interfaces. However, there are still limitations. I was hoping to use the new language features to try a generic approach to abstract algebra with proper operator overloading, but I'm running into the limitation... (more) |

@Marc.2377, your example looks like it will compile. I don't know whether the example signature is the best one for your situation, because I'm very short on context. This may be a situation where you should iterate two or three steps of asking "Why do I want to do that?" and then formulate a new que... (more) |

A: Declaring interface members with generic return types: "The type parameter [generic type] cannot be used with type arguments" The short answer is that it can't be done. C# doesn't support type functions. https://github.com/dotnet/csharplang/issues/339 is probably the issue to follow if you want to track their progress. Workarounds are going to require another type parameter and probably a factory method: e.g. ... (more) |

A: Interpreted language: What is its benefit for being written in that way ? Interpreters are easier to write than compilers. For this reason esoteric and toy languages are often implemented by interpretation. But the dichotomy between interpreted and compiled languages is a false one: a sufficiently popular language which initially has only an interpreter may well lat... (more) |

A: Do we need the fullstack tag? To whether the tag is useful: no. It's useful for tagging people ("this person does frontend and backend") but not questions. I don't see the point of adding "do not use": just delete the tag, which is only on one question. (more) |

@Martin, I know: that was the assumption which seemed reasonable, and I don't think that "requiring that both are present" was in the question when I wrote the answer - but I can't check, because the [history has gone missing](https://meta.codidact.com/posts/279687). (more) |

A: How can I write an egrep (grep -E) regexp that matches lines containing two stanzas in arbitrary order?

A: How to make Microsoft.Build.Evaluation.Project use same base properties as Visual Studio? By forking MSBuildLocator and basically just removing the `#ifdef` it's straightforward to list the available VS instances.

Having tracked things through to https://github.com/microsoft/MSBuildLocator/blob/master/src/MSBuildLocator/MSBuildLocator.cs I'm rather pessimistic: it seems that `Microsoft.Build` is specifically set up to be unable to simultaneously be aware of the existence of .Net Framework and .Net Core, so tha...

How to make Microsoft.Build.Evaluation.Project use same base properties as Visual Studio? `Microsoft.Build.Evaluation.Project` seems to have some rather odd ideas of what values to use when loading projects.

A: What is the point of tagging a question with both a parent and a child tag? Tags also serve for someone who stumbles across the question directly from a third party link to find related content. Perhaps the child tag would suffice if the parent tag is automatically inserted in the page. (more) |

@President, the sieve of Eratosthenes is faster for calculating all the primes from 2 up to N for reasonably sized N, but if you just want the first prime after 2^50 then Atkin-Bernstein should be faster. `LRUCache` is only a performance tweak: for simply running the code, it would suffice to comment...

+1 but I'm wary of the point about best practices. Real praxis is rarely about optimising one factor at the cost of all else: it's about finding a compromise which isn't unnecessarily slow *or* unnecessarily hard to read *or* non-portable without documented reasoning, etc. (more) |

A: Is it recommended for ASP.NET Web API actions to always include a CancellationToken? A cancellation token doesn't inherently do anything.

If the real question is whether to call `ThrowIfCancellationRequested`... (more) |
