git add -p is your friend

git add -p is basically "git add partial (or patch)"

Patch mode allows you to stage parts of a changed file, instead of the entire file. This allows you to make concise, well-crafted commits that make for an easier to read history. This feature can improve the quality of the commits. It also makes it easy to remove parts of the changes in a file that were only there for debugging purposes - prior to the commit without having to go back to the editor.

It allows you to see the changes (delta) to the code that you are trying to add, and lets you add them (or not) separately from each other using an interactive prompt. Here's how to use it:

from the command line, either use

• git add -p

How to Eyeball Your ‘This’ Context in Javascript

The early programmer struggles with the Javascript keyword this. But understanding your this context is easier than it seems.

This is all about where a function is invoked. Often, early programmers worry about where the function was declared. Perhaps the function was declared in a specific file or a particular object. Surely this changes it's this!

Nope.

To understand this, we need to see where it is invoked. Nothing else matters, with one exception which we'll cover in a moment.

Rails Is A Ghetto

I’ve more or less kept my mouth shut about some of the dumb and plain evil stuff that goes on in the Rails community. As things would happen though I’d take notes, collect logs, and started writing this little essay. As soon as I was stable and didn’t need Ruby on Rails to survive I told myself I’d revamp my blog and expose these fucks.

NOTE: This post is currently an open draft. Feel free to comment but it will have spelling and grammar errors and some paragraphs might not make sense. Check my blog and my atom feed to find out when I post the updates.

This is that rant. It is part of my grand exit strategy from the Ruby and Rails community. I don’t want to be a “Ruby guy” anymore, and will probably start getting into more Python, Factor, and Lua in the coming months. I’ve got about three or four more projects in the works that will use all of those and not much Ruby planned.

This rant is full of stories about companies and people who’ve either pissed in my cheerios somehow or screwed ov
