playing with VI editor

This might be helpful to you:

How to remove ^M characters (they are end of line DOS's characters) from a file in vi:

type this
:%s/^V^M//g

where ^V is control-v and ^M is control-m.

:%s is the basic search and replace command in vi and the command you typed will look like this
:%s/^M//g. It will replace what is between the first and second / with what is between the 2nd and 3rd /. Between the first and second slash, we have ^M and between the second and third we have an empty string since we are replacing with an empty string.

g: means to replace all occurences.

Just learned about rsync

I just learned about the rsync command which is amazingly useful. I have been using scp to copy folders from one machine at home to a machine in the lab back and forth and so far it's been good, and dead simple, but always involved extra work like making moving directories around. Now that I learned rsync, I can simply back up my work from the lab to my machine and vice versa using a simple command.

angular.js modules?

I've been playing around with Angular.js and one thing that I haven't really looked at yet are modules. My app currently has only one module. I was thinking that I should probably soon or later refactor it into more defined modules. Today, while searching for something else, I just found something surprising about modules: "Angular Modules are good for nothing...so far. Except for loading 3rd-party angular code into your app and mocking during testing. Other than that, there is no reason to use more than one module in your app. Misko said of multiple modules: "[you] should group by view since views will be lazy loaded in near future". I'd love for someone on the Angular team to enlighten us on what their plans are for that." https://coderwall.com/p/y0zkiw

Cut/Copy and paste in vi

To cut and paste in vi: Get to command mode (press esc) and type mx at the start of the place you would like to cut and go to the position where you want to stop cutting and type d'x. Explanation: m starts a buffer with name x and d'x will cut it . To copy and paste in vi: Type mx and y'x Explanation: same as above except that y'x is meant for yanking (copying) buffer with name x.
