No error , No gain

I'm from a Subversion background and, when I had a branch, I knew what I was working on with "These working files point to this branch". But with Git I'm not sure when I am editing a file in NetBeans or Notepad++, whether it's tied to the master or another branch. There's no problem with git in bash, it tells me what I'm doing.

Anyone tinkering with Python long enough has been bitten (or torn to pieces) by the following issue: def foo(a=[]): a.append(5) return a Python novices would expect this function to always return a list with only one element: [5]. The result is instead very different, and very astonishing (for a novice): >>> foo() [5] >>> foo() [5, 5] >>> foo() [5, 5, 5] >>> foo() [5, 5, 5, 5] >>> foo() A manage..

How do I copy a folder from remote to local host using scp? I use ssh to log in my server. Then, I would like to copy the remote folder foo to local /home/user/Desktop. How do I achieve this? scp -r user@your.server.example.com:/path/to/foo /home/user/Desktop/ By not including the trailing '/' at the end of foo, you will copy the directory itself (including contents), rather than only the conten..

How do you disable autocomplete in the major browsers for a specific input (or form field)? Firefox 30 ignores autocomplete="off" for passwords, opting to prompt the user instead whether the password should be stored on the client. Note the following commentary from May 5, 2014: The password manager always prompts if it wants to save a password. Passwords are not saved without permission from th..

I created a local branch which I want to 'push' upstream. There is a similar question here on Stack Overflow on how to track a newly created remote branch. However, my workflow is slightly different. First I want to create a local branch, and I will only push it upstream when I'm satisfied and want to share my branch. How would I do that? (my google searches did not seem to come up with anything..

How can an int be cast to an enum in C#? From an int: YourEnum foo = (YourEnum)yourInt; From a string: YourEnum foo = (YourEnum) Enum.Parse(typeof(YourEnum), yourString); // The foo.ToString().Contains(",") check is necessary for enumerations marked with an [Flags] attribute if (!Enum.IsDefined(typeof(YourEnum), foo) && !foo.ToString().Contains(",")) { throw new InvalidOperationException($"{your..

If I have an object implementing the Map interface in Java and I wish to iterate over every pair contained within it, what is the most efficient way of going through the map? Will the ordering of elements depend on the specific map implementation that I have for the interface? Map map = ... for (Map.Entry entry : map.entrySet()) { System.out.println(entry.getKey() + "/" + entry.getValue()); } On..

I have an object x. I'd like to copy it as object y, such that changes to y do not modify x. I realized that copying objects derived from built-in JavaScript objects will result in extra, unwanted properties. This isn't a problem, since I'm copying one of my own literal-constructed objects. How do I correctly clone a JavaScript object? To do this for any object in JavaScript will not be simple o..
