These Weekend Links have been very heavily British-newspaper-sourced but here's another one just to complete the set: I've really been the enjoying David Mitchell's Soapbox videos. You'll probably either love him or hate him, but this one brings up something I feel pretty strongly about: "David questions the modern assumption that everything is quicker and easier to sort out by text, rather than via the mystical language of the mouth."

This is the link I am the most excited for this week, and I appreciate my friend Ryan Anderson for sharing it: F.lux. This free download will adjust your monitor settings before and after the sun sets to have a warm glow rather than the harsh blue light that can actually upset your sleep patterns. You can adjust how drastic the change is, but I can say anecdotally it's been fantastic for me. My eyes rejoice! Do you guys have any other monitor or productivity-enhancing apps that you use?
