Convert number to binary in Javascript

Why did it take me so long to find this? Probably because I didn’t use radix in my Google search. Of course. Thanks to “Philip M” for the clue and thanks to for the reference (see here for more on the unary “+” operator to convert a string to number). var str = ’37′; [...]

Adding CSS support to HTML5 in IE6, IE7 & IE8

This is another diamond in the rough I found today. We’re all moving to HTML5, but IE 6-8 has to make it difficult (what’s different, right?). Well, you can get IE to cooperate on a basic level with this little trick. See John Resig’s examples for simple instructions on how to use it. Basically, IE [...]

JSON content type in classic ASP

echo function in ASP

Javascript (actually JScript, whatever): echo = function(x) {return Response.Write(x);} Why didn’t I think of this earlier? Just added this line to my connection file and saved myself 10 keystrokes every time I want to print to screen. The wonders of coding in Notepad.
