OS 10.9 Tips

Mac OS 10.9 Tips

OS X Mavericks adds hundreds of new features, big and small, for you to tinker with. In fact, so many are there that’s it’s easy to miss the gems hidden in bits you rarely look at. Our guide picks out some of the best.

1. Notification Centre Settings
Another new feature of OS X Mavericks is the option to view notifications on your Lock Screen, similar to the way you can on your iOS 7 device. However, you may not want everyone who’s able to have access to your computer reading said notifications.

2. iCloud Keychain Password Suggestions
Using the new iCloud Keychain you can encrypt and save your website usernames and passwords to use across all your Apple devices. OS X Mavericks pre-fills all theentries for you as well, and it’s particularly useful on the iPhone 5S where inputting passwords is more of a pain because of the small touchscreen keyboard.

3. Do Not Disturb on your Mac

Like with iOS devices you can turn off pesky alerts and notification pop-ups when you want some quiet time on your Mac. If you scroll down, you’ll see a ‘Do Not Disturb’ option that will turn off all alerts until tomorrow.
4. Customise your Time Machine back-ups
Apple has introduced customisation options within your Time Machine back-ups that will allow you to leave out specific content. This is especially useful for temporary content that’s merely having a little holiday in your hard drive rather than setting up a permanent camp.
5. Get Emoji Quickly
If you’re addicted to the wide range of Emoji (or smiley faces) available on your iOS device, you’ll be pleased to hear you can now get Emoji on OS X Mavericks via a quick shortcut. You’ll be able to bombard your contacts with Emoji in your emails, iMessages and other text stuff by hitting the Command + Control + Space buttons at once to bring up the Emoji keyboard.

Green IT

What is Green IT or IT Sustainability

Some people are of the opinion Green IT is a fad…A short lived fancy…Something here today but gone tomorrow….

The reality is Green IT or IT Sustainability refers to the study and practice of using computers and IT resources in a more efficient and environmentally responsible way. Computers and computing eat up a lot of natural resources, from the raw materials needed to manufacture them, the power used to run them, and the problems of disposing them at end of life.

In a nutshell, Green IT or IT Sustainability is composed of two things:

1. Minimising the negative impact of information technology use on the environment

2. Using information technology to help solve environmental issues

As you can see these are almost two areas at opposite poles. In our lives technology helps us to do everything from send a funny joke to our friends, to make sure the trains run on time, to allowing us to warn cities of tsunamis and earthquakes. We need it and it isn’t going away any time soon. On the other hand a typical computer is made up of thousands of chemicals and if we put all the computers in the world together, they use massive amounts of electricity.

How can technology help?

Apart from technology causing some environmental issues, it is also one of the best tools we have available to the human race to help us understand how we can fix environmental issues.

For example, technology can help us achieve things such as climate change modelling. Climate change modelling requires massive computer processing capability. Super-fast computers are sitting in labs across the world calculating scenarios for our future – how much will the sea rise? Which countries would be wiped out? How long will it take?

Another example of technology helping to solve environmental issues is carbon sequestration. But what is carbon sequestration? Well without getting into a science class discussion, it’s really about storing excess carbon. At the moment you probably know that trees store carbon but we simply don’t have enough trees to store all the carbon we produce. So we need to look for other places to store carbon. There are numerous proposals from scientists on how we do this, including storing it underground or in the sea. However before we go drilling places around the world and disturbing the flora and fauna, computers can help identify suitable storage areas – without the unnecessary drilling.
