Should you buy an iPad Air or mini Retina?

Posted on 03:06 by Unknown
The iPad Air goes on sale tomorrow and no doubt there will be huge queues outside of Apple stores across the country and even across the world. Or will there? The queues could be smaller this time around because Apple is launching the two new iPads - the Air and the mini Retina - on different dates.



Some people will want the iPad Air, but others will choose to wait for the iPad mini Retina. This will reduce the queues and it will mean that stores are less likely to run out of the model you want compared to previous years where there was just one new iPad.

So which iPad should you buy? If you check the specifications on the Apple site, there is only one difference between the two new models. Screen size. Same processor, memory, iOS, apps, Wi-Fi, and so on. Even the screen resolution is the same. There isn't anything you can do on an Air that can't be done on an mini Retina and the performance should be identical.

The choice is therefore between a 7.9in or a 9.7in screen.

As an iPad 2 owner, I had already decided that it was about time I upgraded. Although the iPad 2 still runs every app I've tried on it, it is sometimes slow and it struggles with apps that push it to the limit, like games. Also, I can't prise it out of the hands of the rest of the family, so I rarely use it myself and spend more time on cheap 7in Android tablets. A second iPad would be useful.

The iPad mini Retina would save money and be just as good as an Air, but one thing puts me off and that's the small text that many apps use. What is fine on the the full size iPad's 9.7in screen could well be difficult or even impossible for me to read on a mini's 7.9in screen. Because the screen resolution is the same on both iPads, I suspect that developers will not take the reduced screen size into consideration. They'll simply display the app on the mini the same way they do on the full size iPad and this means that everything, including text, will be 20% smaller. Will it be readable?

The size of text on the screen is a continuing irritation for me and I recently had an iPhone app that had text so small I couldn't read it. I had to install the app on an iPad to read the instructions, menus and buttons. Once I knew what everything was I could then use the iPhone app. This shouldn't be necessary, but it is far too common.

High resolution retina displays have encouraged app developers to use ever-smaller font sizes so they can squeeze more on to the limited screen space of phones and tablets, but this reduces usability and can even make it impossible to some people to use them. I have actually deleted apps after using them for just five minutes because the text was so small it made my eyes hurt with the strain of reading it. Retina displays have a downside.

As you get older, your eyes get worse, but it would be wrong to assume that this is just an age thing. Of course, your granny will have trouble with small text on a tablet or smartphone, but just look around you at the number of ordinary people of all ages that wear glasses. Many people, including young people, don't have perfect vision and they struggle with tiny text. I wish developers would stop using such small text and test their apps with real people with all their faults and not just a few elite teenagers with eyes like a hawk.

For me the choice between the two tablets is between comfortable reading or headache-inducing eye strain. I guess I'll have to fork out the extra cash for the bigger model even though I'd like the smaller one. At least I'll get my hands on it sooner rather than later.

Find free images on Google

Posted on 14:17 by Unknown
If you are looking for a photo for your ebook, blog, Facebook page or website, there are countless images available the web and a Google image search will produce hundreds to choose from, no matter how obscure the subject.

The problem is that a lot of the images are copyright and it is not legal to take them and use them in your own works. You could get in trouble if you copied someone else’s photo from the web and used it without their permission. Here is a useful tip to find legal images that you can use in any way you like.

Go to the Google home page and down at the bottom of the browser is a Settings link. Click it and then select Advanced search in the menu that is displayed. On the advanced search page, enter the subject or object you want to find in the boxes at the top. Suppose, for example, you wanted to find some free images of elephants, you would enter 'elephants' in the top box.

Now scroll down to the bottom of the advanced search page and  next to Usage rights, select one of the free-to-use licenses, such as Free to use or share, even commercially. Now click the Advanced search button.



This performs a standard web search, but then you can select Images to see image results. All the images are free to use, as per the license you searched for. However, you should always read the details on the website it comes from because sometimes you have to credit the photographer.

Click Search Tools at the top of the page and there is a menu to filter the images by license, which saves you having to go back to the advanced search page and start again.

How to use Windows 8 search to find stuff

Posted on 13:27 by Unknown
The biggest change in Windows 8, and one that continues in the upcoming 8.1, is the Start screen. Instead of having a menu that lists all your applications, there is a Start screen that contains tiles for a few key items.

One of the problems with the Start screen is that is just doesn't show everything. A typical example is Task Scheduler. It is on the Start menu in Windows 7 and you just go to Start, All Programs, Accessories, System Tools, Task Scheduler.

Task Scheduler is not on the Windows 8 Start screen. No problem, just search for it. You can simply start typing on the Start screen to bring up the search screen to find stuff. However, if you type 'task scheduler' then Windows 8 search says that there is no such program.


There are no apps and no settings. Has Task Scheduler been taken out of Windows 8? No it hasn't and you just have to type in 'schedule tasks' instead.


This time there is one item in Settings and selecting this shows an item called Schedule Tasks on the left side of the screen. Click that and it runs Task Scheduler.

This is really odd behaviour and it can be confusing when looking for certain programs and tools that you may have used with earlier versions of Windows. It is unclear why a search for 'Task Scheduler' does not list Task Scheduler, but Windows 8.1 is no better. In fact, it is worse because it lists lots of Bing search results, like weblinks to sites like Wikipedia and others instead of the program you actually want.

Searching for Disk Cleanup (which is now called Disk Clean-up in Windows 8), is slightly better and search returns a result called 'Free up disk space by deleting unnecessary files'. Clicking it runs Disk Clean-up.

It seems that you cannot use Windows 8 search to find applications you know the name of. Instead, you must search for the action you want to perform. So to find Task Scheduler you don't enter its name, you enter 'schedule tasks' and to get Disk Clean-up you enter 'free up disk space'.

So if you can't find something in Windows 8, try typing what you want to do, rather than what something is actually called.
