Bridging Native & React for iOS & Android

React Fiber is an ongoing reimplementation of React's core algorithm. It is the culmination of over two years of research by the React team.

brew install ImageMagick

ffmpeg -ss 14:55 -i video.mkv -t 5 -s 480x270 -f image2 %04d.png

-ss 14:55 gives the timestamp where I want FFmpeg to start, as a duration string.
-t 5 says how much I want FFmpeg to decode, using the same duration syntax as for -ss.
-s 480x270 tells FFmpeg to resize the video output to 480 by 270 pixels.
-f image2 selects the output format, a series of still images — make sure there are leading zeros in filename.

SSH into your EC2 instance. Run the following:

$ sudo yum install gcc This may return an "already installed" message. That's OK.

$ wget http://download.redis.io/redis-stable.tar.gz && tar xvzf redis-stable.tar.gz && cd redis-stable && make

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	What is redash?
	Redash is database viewer included BI tool inside. Redash has support for querying multiple databases, including: Redshift, Google BigQuery, PostgreSQL, MySQL, Graphite, Presto, Google Spreadsheets, Cloudera Impala, Hive and custom scripts.

	Prerequisite :
	1. Install docker
	2. Install git

	git clone https://github.com/getredash/redash.git
	docker-compose -f docker-compose.production.yml run --rm server create_db
	docker-compose -f docker-compose.production.yml up

	to check if the server works - https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice
