How to make a 1 click connect to bluetooth device button

making a shortcut

• Install Bluetooth Command Line Tools
• you can use the command line tools to display all device ids by simply running btdiscovery
• Create a Connect batch script:

ClickerMonkey

// when T is any|unknown, Y is returned, otherwise N
type IsAnyUnknown<T, Y, N> = unknown extends T ? Y : N;
  
// when T is never, Y is returned, otherwise N
type IsNever<T, Y = true, N = false> = [T] extends [never] ? Y : N;

// when T is a tuple, Y is returned, otherwise N
// valid tuples = [string], [string, boolean], 
// invalid tuples = [], string[], (string | number)[]

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

require 'pi_piper'
require 'ostruct'

laser = PiPiper::Pin.new(pin: 17, direction: :out)
alarm = PiPiper::Pin.new(pin: 18, direction: :out)
vibration = PiPiper::Pin.new(pin: 27, direction: :in)
i2c = PiPiper::I2C.new

def turn_on(pin)
  pin.off

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Design rules

First couple things I thought about when migrating after reading the docs

So migrating my existing app wasn't as troublesome as I originally thought. First thing I did was take a look at my router and routes and figure try to make a mental model of all the files where I had nested routes in the existing app because those components/containers will contain {this.props.children}. So I need to replace those with the nested <Match /> components.

So just to give an example:

In v2:

<Router history={history}>
  <Route path="/" component={App}>

/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).
