Keep Your Mac Awake With Caffeine

March 17, 2013 Leave a comment

Tired of your Mac falling asleep when it should be doing your bidding?  Maybe you’re running a service on it you need  24/7 access to?  Apple seems to be a little too environmentally friendly some days.  It’s hard to keep a Mac completely awake – no matter what you do in System Preferences.

I have a VOIP VM that I occasionally run on my iMac.  Despite setting my iMac to “never sleep” in its System Preferences, the VOIP server would frequently unregister and cause phone outages because the Mac was going to sleep anyway.

A free program called Caffeine solved my problems.  Check it out at the Lighthead website or install it from the App Store.  You can easily turn it on or off indefinitely or for an amount of time.  It simply and effectively keeps your computer completely awake, display and all, or allows it to keep its normal sleep schedule.  Maybe it can help you, too.



Generate Electricity While you Play

Energy Harvesting is a growing field that may become significant in our lives someday.  Here’s a link to a great article on harvesting energy from a soccer ball.  Looks like it’s making a debut on Kickstarter, too.

While the article isn’t explicit about real world application, I imagine a model where the kids go out to play soccer for an hour or two and then the ball is brought back so the energy can be consumed.  What I’d like to know is do child labor laws apply?  😉

PlayLater: Online PVR Bliss?

Check out  I’ve been researching ways to cut cable without getting the shakes too hard.  This looks like a potentially handy tool.

On another note, I wonder if this is another way to get your Netflix content on a Linux box.  It’s probably a few extra steps, but might be handy.

Let us know if you’ve tried it out!

Free VPS

March 8, 2013 Leave a comment

Ever wanted a server “in the cloud” so you could do things like proxy web traffic, or put up a PageKite for personal use?  Unfortunately, a VPS is expensive for the average DIYer who wants one for occasional personal use.

If you only need a light-weight VPS, search no more.  Buy a Raspberry Pi and put it in a Colo for free!  Follow the link to EDIS and see if they might be a good option for you.  If nothing else, it just might put you on the list of who’s who of nerddom.
