I just discovered a CSS hack that applies to IE6, 7 and 8. It is basically just \9 right after the property declaration, but before the closing semicolon.

For example:

div {
    -ms-filter: "progid:DXImageTransform…";
    margin-right: -2px\9;
}

Plucked from a more comprehensive list of hacks at paulirish.com

This is starting to get a little out of control with IE6, 7, 8 and 9 on the horizon. this is beginning to look like a much better idea…

I recently wrote this (partial) piece of PHP code to generate a list of months in a year:

for ($i=1; $i<=12; $i++) {
    $monthStamp = mktime(0, 0, 0, $i);
    echo date('F', $monthStamp);
}

Today, I suddenly have two “February”s in the list. Not Good. I missed the part in mktime()‘s docs that mentions that missing arguments will default to the current time, so the code was generating a timestamp for Feb 29 2010 (which mktime() interprets as Mar 1 2010).

So note to self—the fix is explicitly specifying the day of month (just “1″ in this case):

for ($i=1; $i<=12; $i++) {
    $monthStamp = mktime(0, 0, 0, $i, 1);
    echo date('F', $monthStamp);
}

I had trouble finding the right incantations on Apple Terminal to make the ⌥← and ⌥→ shortcuts work.

The instructions are right here.

When XHTML was all the rage years ago, it was common knowledge that an XML prolog declared before the doctype will trigger quirks mode in IE6. That has been fixed in IE7.

However, I found out that actually anything at all, except for white spaces and the XML prolog, will trigger quirks mode in IE6, 7 and 8 for doctypes that should otherwise trigger standards mode.

So if someone decides to add <!-- $Id$ --> to the first line in the HTML file, it will trigger quirks mode in IE. Now you know too.

So Mosaic‘s source code has just been released on GitHub, and a sharp eye at Reddit has already spotted this gem (keep in mind that IE is originally derived from Mosaic).

Assuming that IE was actually derived from this code base, may I present the reason we had to work around PNG24 for almost a decade:
