Even shorter quine

tonyonodi / image_quine.js

Created December 30, 2015 18:27

Code that outputs its own source to a canvas as grayscale values.

	(F=(L,d)=>{(C=d.createElement("canvas")).width=C.height=L;X=C.getContext("2d");for(i=L*L;i--;)X.fillStyle=`rgb(${n=`(F=${F})(16,document)`.charCodeAt(i)\|\|32},${n},${n})`,X.fillRect(i%L,0\|(i/L),1,1);d.body.appendChild(C)})(16,document)

	// After running this code you should be able to grab the pixel values as a Uint8ClampedArray
	// from the canvas context 'X' and use that to verify like so:

	var charCodes = Array.from(X.getImageData(0,0,16,16).data).filter((_,i)=>i%4===0)
	String.fromCharCode.apply(null, charCodes)

	arr.length - i == 1 ?
	`${acc}${conjunction} "${str}"` :

tonyonodi / bytes_to_int.clj

Created July 21, 2016 14:05

Convert byte array to integer in Clojure

	; Adapted from http://stackoverflow.com/a/13041851/3122246 the way it goes about converting (converts to list of
	; strings, then to a string then reads the string) is kind of ugly but the code is nice at least.

	(defn bytes->int [bytes]
	"Converts a byte array into an integer."
	(->>
	bytes
	(map (partial format "%02x"))
	(apply (partial str "0x"))
	read-string))
