Example showing the problem described in icsharpcode/ILSpy#684. Code originally written for [02242 Program Analysis](http://www.kurser.dtu.dk/02242.aspx), the language used is called While+ (but note that there are a couple of slightly different languages with that designation used in analysis and semantics litterature).

	// Program
	static int Main(string[] array)
	{
	int[] array2 = new int[1000];
	int num = int.Parse(Console.ReadLine());
	if ((num >= 1000) ?? (num < 2))
	{
	Console.WriteLine(-1);
	}

poizan42 / mandelbrot-pdf-256x256.py

Created July 21, 2015 23:11

Some experimentation with creating a pdf with a 256x256 Mandelbrot set rendered by the viewer by using a tint transform. Viewers generally seems to reduce the precision to 8bpp before passing the data on to the tint transform, so it doesn't work

	#!/usr/bin python
	pdf = """%PDF-1.4
	1 0 obj
	<< /Type /Catalog
	/Outlines 2 0 R
	/Pages 3 0 R
	>>
	endobj

	2 0 obj

poizan42 / Mandelbrot16x16-fixed.pdf

Last active August 29, 2015 14:25

16x16 Mandelbrot set rendered by a tint transform (it's not technically a valid pdf because it lacks lengths and the xref table which is hard to write by hand, but every reader can reconstruct them anyways). The Mandelbrot16x16-fixed.pdf file has been opened and saved with Adobe Reader which repairs the file (but makes it human unreadable).

Sorry, something went wrong. Reload?

PHP q_encode

	/*
	Konverterer en streng til Q-encoding
	En del spam filtrer ser ud til at regne det for mere sandsyneligt at en mail er spam hvis
	subject og from er base64 encodet - og der er ingen grund til at udfordre skæbnen...
	Q-encoding er en modificeret udgave af quoted-printable, som benyttes til mime headers
	quoted-printable er beskrevet på wikipedia på http://en.wikipedia.org/wiki/Quoted-printable
	forskellene der er i Q-encoding er beskrevet på http://en.wikipedia.org/wiki/MIME#Encoded-Word

	Der er faktisk en funktion i php til at gøre dette - iconv_mime_encode -
	denne encoder bare ikke alting korrekt (mellemrum som =20),
