JQ to filter JSON by value

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

Chromatic aberration effect - a simple implementation in JavaScript

A chromatic aberration is an optical effect caused by one or more color channels being displaced. Although it is an optical failure and should be avoided for displaying or image capturing devices, chromatic aberration can be used to make graphics be more realistic in some other applications like 3D games.

The following codes is an example of implementing the effect using ImageData API of HTML5 canvas. By fetching and manipulating pixel data of the image, the chromatic aberration effect is easy to achieve.

	Python 3 code that can decompress (to a .gvas file), or recompress (to a .savegame file)
	the UE4 savegame file that Astroneer uses.

	Though I wrote this for tinkering with Astroneer games saves, it's probably
	generic to the Unreal Engine 4 compressed saved game format.

	Examples:

	package main

	import (
	"fmt"
	"syscall"
	//~ "time"
	"unsafe"
	"golang.org/x/sys/windows"
	)

	package main

	import (
	"fmt"
	"sync"
	"time"
	)

	func main() {

	// gif by dave
	// @beesandbombs
	// :)

	int[][] result;
	float t, c;

	float ease(float p) {
	return 3pp - 2pp*p;
	}
