How To Work With Multiple Github Accounts on a single Machine

Let suppose I have two github accounts, https://github.com/rahul-office and https://github.com/rahul-personal. Now i want to setup my mac to easily talk to both the github accounts.

NOTE: This logic can be extended to more than two accounts also. :)

The setup can be done in 5 easy steps:

Steps:

Step 1 : Create SSH keys for all accounts
Step 2 : Add SSH keys to SSH Agent

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Developer tips

Record a video of your app

Developer options -> Check show touches
adb shell screenrecord /sdcard/video.mp4
adb pull /sdcard/video.mp4

This short code will show how to sync database file using Realm, but can be used for any file that you need to send to Wear (using Data API). It just takes any file, change it to Asset object and send it over to Wear device. Also it can be used Mobile->Wear, and Wear->Mobile.

When you need to sync database just call FileSender.syncRealm(context);, that is it!

DISCLAIMER "Proper" way would be to synchronize each transaction to DB, but it in most cases Wear is used very rarely comparing to mobile, so it would most likely cause a battery drain. My idea was to synchronize it only whene it is needed (so for example when app closes). If you want to make sure that you are using latest DB, just send trigger data using MessageAPI from Wear to Phone with ask of syncing over its database, or keep some timestapm of last edit and check it.

Send uncaught Exceptions from Android Wear to Android

This is a short Gist showing how I transmit any uncaught exceptions happening in the Wearable part of my App to the connected Smartphone/Tablet. This is necessary because Android Wear devices are not directly connected to the Internet themselves.
