The commit message is from Git, but it is actually the editor that keeps you from quitting. This is because Git uses your default editor, which for a variety of reasons is usually set to vi (it might be something else on your OS, like pico). To write a commit message and get out of VI, follow these steps: press i (i for insert) write your merge message press esc (escape) write :wq (write ...

Starting with Visual Studio 17.7, standard users can update or modify their installation if a proper policy is set by an administrator. This still doesn't permit fresh installations without admin rights, but once Visual Studio is installed with admin privileges and the AllowStandardUserControl policy is set (by adding a simple registry key value), subsequent updates or modifications won't need ...

i＝1，为什么 (++i)+ (++i)＝6？我觉得应该等于 2＋3＝5。 所以 (++i)+ (++i)+ (++i) = 10 是有可能的，但你真的很难预计编译器在背后做了什么。 你可以用反汇编去了解，但在未反汇编之前，你无法估计它会做什么。所以，未定义行为。 另外，上面这个例子是在 求值过程中的副作用与顺序点 这里拿下来的 ...

I see and I forget, I hear and I remember, I do and I understand是孔子说的吗？出处在哪里?

Só para complementar: colocar os ++ antes da variável tem o nome de operação de pré incremento e colocar os ++ depois da variável tem o nome de operação de pós incremento. Também é valido para operações de subtração: --i (pré decremento) e i-- (pós decremento).

В связи с наступлением на нас шаблонов в С++, рекомендуется писать в циклах ++i а не i++. Это связано с тем, что прединкремент для классов обычно реализуется проще, чем постинкремент (как минимум, не надо хранить старое ...

Alternative solution, with GitLab 13.11 (April 2021) Force push option for protected branches It’s best practice to prevent force push on Git repos, but exceptional cases may occasionally require it. Temporarily removing branch protections in order to conduct a force push may not always be ideal as it requires maintainer access, and causes the settings for branch protection to be lost ...

Also this is manifestly what you probably want if your question is, "Where did I branch from?". For me, at least, I have a branch B, which represents some incremental work I did on one part of the tree, and I want to pick up (in the manner of cherry-pick) that work and apply it to some other spot in the tree. So I want to identify the spot where branch B branched off of some other mainline-ish ...

Given a change that has been committed using commit, and then reverted using revert, what is the best way to then undo that revert? Ideally, this should be done with a new commit, so as to not re-...

I'm trying to get my head around the use of the tilde operator, and associated functions. My 1st question is why does I() need to be used to specify arithmetic operators? For example, these 2 plots
