Open Firefox.
Open a webpage with a scroll-bar.
Hold down the left mouse button on the scroll widget (whatever it's called.)
Move the mouse off the Firefox window, to the right.
Right-click (while still holding the left mouse button.)
Let go of the left mouse button.
Move the mouse back into the Firefox window.
Move mouse up and down to scroll without having to click.

Technical explanation:

The "mouse-up" event will have been lost, and you'll still be in control of the scroll bar, without having to hold any buttons down. Click the left mouse button again to generate a new mouse-up event and stop scrolling.

It's a bug, obviously, but it's a kinda neat and useful one.

Sometimes I swear spam hates me.

One of the most irritating repeating problems in programming is dealing with humanity's absolutely insane calendar. 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day. Except for leap seconds. Somewhere between 28 and 31 days in a month, depending on the month, and the year. 365 or 366 days in a year - 365, except every fourth year, except every hundreth year, except every four hundreth year. I imagine there are more "excepts" that I don't know about.

Remember that these days are not necessarily all the same length.

AM comes before PM, except for 12:xx, which is reversed. Of course, it's not the same time all over the world - every place has its own time zone, most (but not all) of which are offset by exact hours. And some places even change time zones twice a year - for example, most of America, except Arizona and the east half of Indiana, which don't. (Except, apparently, the Navajo Indian Reservation in Arizona. Which does.)

Basically it's a mess, and while I can gratefully ignore about 80% of the mess, the 20% I'm having to deal with is seriously irritating me.

Which makes it even more annoying when I open my inbox and find an email titled "Everything you need to know about dating!"

PLEASE. TELL ME. SAVE ME FROM THIS HELL.
