So I got annoyed at always having to reconnect to Stetho, and I figured there would be some better way to do this in Android Studio ... and maybe there is, but this is the best I've gotten so far. Putting this together in a gist was inspired by a question on reddit: https://www.reddit.com/r/androiddev/comments/7hz3xy/stetho_anyone_know_of_a_convenient_way_to/

How does this work?

• Use Android Studio custom Run configuration to call a new gradle task :app:launchStetho before the app launches
• The gradle task uses launchctl (docs) to start an out-of-band AppleScript automation open-stetho.applescript
• The AppleScript waits a few seconds, then controls Chrome to open chrome://inspect and loops until the "Inspect" action is available, and then executes a click() against that DOM element

Setup

1. Choose a location for the applescript and ensure that it's executable `chmo

System Design Cheatsheet

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

Basic Steps

1. 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?

Centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries.

A very good way is to separate gradle build files, defining something like:

root
  --gradleScript
 ----dependencies.gradle

#Intro

Kotlin is a new programming language for the JVM. It produces Java bytecode, supports Android and generates JavaScript. The latest version of the language is Kotlin M5.3

Kotlin project website is at kotlin.jetbrains.org.

All the codes here can be copied and run on Kotlin online editor.

Let's get started.

If you want to your CommonJS modules to work in both Alloy and plain Titanium projects, you might need a way to detect if you're in Alloy. For instance, if you're in Alloy you would get Underscore from the alloy-module, while in plain Titanium you would require Underscore directly.

Well, you can:

var _ = require((typeof ENV_TEST === 'boolean') ? 'alloy' : 'underscore')._;

The above works by utilizing Alloy's optimization process. In this process, constants like ENV_TEST will be either TRUE or FALSE. The actual expressions in wich they are used will then be evaluated. If FALSE the code block will be removed. In plain Titanium projects the constants are undefined and this typeof ENV_TEST will be undefined, so the code block will be executed.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
