Why I hate TypeScript

Warning: These views are highly oppinated and might have some slightly incorrect facts. My experience with typescript was about 2 weeks in Node and a week in angular2.

Not Standard

TypeScript is implementing their own take on JavaScript. Some of the things they are writing will likely never make it in an official ES* spec either.

Technologies that have competing spec / community driven development have a history of failing; take: Flash, SilverLight, CoffeeScript, the list goes on. If you have a large code base, picking TypeScript is something your going to be living with for a long time. I can take a bet in 3 years JavaScript will still be around without a doubt.

Its also worth noting that they have built some things like module system and as soon as the spec came out they ditched it and started using that. Have fun updating!

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

Android Recyclerview GridLayoutManager column spacing Here is the question, the first answer does not work well in my project,and it makes the spacing bigger between item and item. the second answer is quite perfect.But if RecyclerView has headers,it does not work well. Then I fixed it.

import android.graphics.Rect;
import android.support.v7.widget.RecyclerView;
import android.view.View;
