In the New Yorker, psychologist and author Maria Konnikova examines studies showing that Facebook — and Internet use in general — makes people unhappy, along with those showing just the opposite, that Facebook use makes people happier, increasing social trust and engagement. How could this be? She teases out the fact that the research showing negative effects may have focused on passive use (scrolling through newsfeeds), whereas those evincing positive effects looked at active use (posting, “liking,” and so on). In short, engage with life online, don’t let it just wash over you. follow link
Cull Graphics Quickly with Preview
You're faced with a folder full of images, and you need to sort through them, trashing some number and keeping the rest. For a quick way to do that, select them all, and open them in Preview (in Leopard, at least). You'll get a single window with each graphic as an item in the drawer. Use the arrow keys to move from image to image, and when you see one you want to trash, press Command-Delete to move it from its source folder to the Finder's Trash. (Delete by itself just removes the picture from Preview's drawer.)
