Mac Users: Please, please, please set up Time Machine!

I ran into the librarian at my son's school yesterday and saw that she had a new Mac. Her old one had died unceremoniously, but the administration had the budget to replace it quickly. One thing I noticed, though, is that she had not yet setup Time Machine on the new iMac.

Mac users, there is no reason NOT to set up Time Machine on your Macintosh. This feature, added with Mac OS 10.5 backs up your entire Mac -- data, applications, settings -- and then updates any changed files on an hourly basis. All it takes a an external hard drive (I usually recommend on about 250GB in size). Theses drives are on sale all the time for prices around $50. This is a great investment to give you substantial peace of mind about your Mac.

While Apple touts the ability to easily restore deleted or damaged files using Time Machine, my use of the software has almost always been to restore a Mac that has crashed or build a new Mac that looks exactly like and old Mac -- including email, settings, desktop pattern, printer, everything!

I had a client who happened to get a lemon iMac. The unit died after 2 weeks, but we had set up time Machine from the very beginning. It had taken several hours to move data from her Windows machine and set the Mac up the way she wanted it and all that would have been lost if we didn't have a Time Machine backup. Instead, we were able to plug her backup drive into the new Mac, select "Restore from Time Machine Backup" during the setup and about 15 minutes later she was working again -- with all her original settings.


I recently had to replace my Time Machine backup drive, as I was using an older, leftover drive I had lying around the office. I found this Seagate FreeAgent Go drive (250GB) on sale at a local retailer. I like it, as it is small, quiet and requires no external power cable. It is powered directly from USb port of the computer.

Mac Users -- if you haven't set up Time Machine on your mac -- DO IT TODAY! You have nothing to lose and everything to gain -- including peace of mind.

Hey, how do I make it so that when my external HD is full that Time Machine will delete files until it has room to do the back up?
Time Machine intelligently manages the usage of the hard disk, purging older backs as new material is added, there is no need to manage it manually. That said, in order to maintain a history of backups into the past, you will want a hard drive large enough to contain probably double the actual size of applications and data on the hard disk. This gives Time Machine som breathing room to archive the incremental changes that occur.

For my clients a 250 GB is usually fine as it is rare for them to use more than 40-50 GB of their hard disks.

This DIY domino clock tells the time using three LED-lit tiles via Arduino Blog

After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own. The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s device uses addressable RGB LEDs as dots that allow for a variety of colors to shine through.

On my iPhone…IFTTT (If This Then That) for iOS

IFTTT (If This Then That) for iOS IFTTT (If This Then That) for iOS My best description of IFTTT, both their main web site, and this new iOS app is "a scripting language for the We." It allows you to set up "recipes" that watch one particular service, like Feedly, Evernote, Gmail and more, and then take action on another service whenever a particular action occurs. I use this to automatically save my shared items from Feedly and elsewhere into an Evernote Notebook and also use it to post automatically post information on a variety of services. The iOS app adds to this functionality by allowing you to take various actions on your phone and triggering IFTTT actions whenever they occur. In the case of the iPhone, initiating actions can include adding new contacts to your iPhone, taking a new picture and more.  For more complete information on how IFFTT works, visit ifttt.com    From the iTunes App Store...
