A Beginner's Hip Hop Playlist

Edit: After some constructive feedback on hacker news, I think that it's worth mentioning that this playlist is very skewed towards recent material, although I've included some essentials from the past.

I think that hip hop is one of the most, if not the most, misunderstood genres of music. In this playlist, rather than focusing on one artist or one type of hip hop, I tried to give examples of a bunch of different artists with songs ranging from the early 90's all the way up until 2017. The songs are in no particular order and the sounds cover a very broad spectrum. Some of them are pretty damn explicit, so I wouldn't necessarily throw this playlist on if there are kids around. I provided the lyrics to each song, the sub-genre that I'd put the artist in (very rough), and a brief description. This playlist is not by any means meant to be comprehensive and in many cases doesn't necessarily represent the artist's "best" song, but instead aims at exposing you to some of my fa

When you create a npm package, remember it might be used in a browser or a server, or even a command line utility… For each package you create, please pay attention at what it will be used for:

1. Is it going to be used as a dependency to a nodejs application that is not bundled? (e.g. command line utilities)
2. Is it going to be used as a dependency to a nodejs application that is bundled? (e.g. AWS Lambdas)
3. Is it going to be used as a dependency to a browser application (always bundled)?.

• In cases 2) and 3) you want to allow for tree shaking.
• In cases 1) and 2) you want to benefit from the "ES6"/"ES next" features supported natively by nodejs.
• In case 3) you also want to benefit from the native support of "ES6" from your browser.

Everything I Know About UI Routing

Definitions

1. Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
   1. pathname - The "file/directory" portion of the URL, like invoices/123
   2. search - The stuff after ? in a URL like /assignments?showGrades=1.
   3. query - A parsed version of search, usually an object but not a standard browser feature.
   4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
   5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.
