I have a switch statement that executes some logic over and over. Rather then use cut and paste I wanted to put it into a function, but I am failing badly at this. This is what I want to do, but it does not compile because the break tag in the function does not exist. Can anyone refactor this to a better working version? switch(param...

Hey guys, I am using an image switch function in Jquery for a site I am building. There are a ton of projects so I am heavily compressing a lot of these images. Some of them however dont look nice as .gifs and it really only makes sense to make a .jpg. My problem is that this code only swaps one image, to another image of a different n...

I know I can use a flag, and break from the loop by pu...

Sometimes I'm in a feature branch, but I've made an unrelated change that I want to see in master. Often I can just do: git checkout master git commit -m "..." filename But sometimes when I do the checkout I get a warning that there are local changes and thus I can't switch the branch. Why does this only happen sometimes? Is there ...

However, there is one scenario (which has already been discussed on this site) which I could come up wit...

I have read a few articles around alternatives to the switch statement in Python. Mainly using dicts instead of lots of if's and elif's. However none really answer the question: is there one with better performance or efficiency? I have read a few arguments that if's and elifs would have to check each statement and becomes inefficient wi...
