A lot of folks get confused about how to measure the visual size of photos and other images that are created or viewed on their computers.
The simplest way is by counting how many pixels (tiny dots) were used to make that image. A thumbnail-size photo, like those in your Friends List on Facebook, might only be 50 pixels wide by 50 pixels high. The video you watch on YouTube might be 560 x 315 pixels. A photo that fills the entire screen on your laptop might be something like 1280 x 800.
The mental trap to avoid is measuring the images on our screens using inches or centimeters. We’re all looking at different devices, whether it’s a phone in our hand, a tablet on our lap, or a computer on our desk. Different screens fit more or fewer pixels into each inch on that screen. Therefore, an image the size of a postage stamp on my laptop screen, might be the size of a wallet photo when displayed on your older computer monitor, but the size of fingernail on your smartphone.
In a world where we view most images on a screen, there are no inches, there are only pixels — until you print the picture.

Having concluded that the two best calendar applications for the Mac seem to be BusyCal and Fantastical… Having realized that they can each be used alone, or in combination with the other… Telling you that they can also be used with or instead of iCal or Outlook… Planning to synchronize my professional and personal calendars to “the cloud”, using BusyCal…
I was delighted to discover that both apps are included in this software bundle for $40 — less than the $50 price of BusyCal.
The bundle also includes LaunchBar (my geeky keyboard shortcut tool of choice), and five other apps: Default Folder X, Tags, Cashculator, Notebook and Home Inventory (in descending order of interest, to me).
This deal expires December 19th. I already ordered and downloaded mine.

A Facebook friend is curious why Steve Job’s life has gotten so very much attention, with his untimely death. This was my personal response:
As a lifelong student of history and technology, I’m fascinated by Jobs, because historians yet unborn will be writing about him (and school children will read about him) the way we still study Edison or Ford. Although human advancement is a collaborative enterprise, some individuals have the vision and drive to advance the quality of progress for all of us. The rest of us are drawn to such mojo, wanting to grok (or even glimpse) the mechanism of greatness. It’s a mystery on par with “What is love?”

I can’t think of any reason to teach little children to use a Windows or Mac computer. Introduce them to the future with a truly personal computer: iPad.
Why not teach them to use a “real” computer? Well, why not teach them to use a typewriter? Looking at the combination of hardware and software which we’ve come to think of as a normal computer, I think it will feel like an IBM Selectric typewriter, by the time today’s toddlers graduate from college.
At this point, some of you are shaking your head thinking, no way is that cute little iPad gonna replace the powerful computer with which I do real work. People who think that way are just one of the reasons the change I’m predicting will happen gradually, while today’s 3 year olds are growing up. A bigger reason is we’ll have to wait while tablet computing hardware and software evolves and realizes its potential. It’s still early days; for years after the first desktop computers had become available, most desks were still dominated by a typewriter or blotter pad.
iPads, iPhones and Android smartphones are already selling by the tens of millions, every quarter. It’s taken Apple 2 years just to catch up with the demand for iPads. You already see executives using these to work, on the road and at home. At first, many entered the workplace via the backdoor and personal purchases, not the IT department. That’s exactly how it happened with the first personal computers. But I also know of IT departments issuing these tablet and pocket computers, to do real work, often replacing traditional business tools, like laptops and Blackberries.
Think how few typewriters you see in the workplace, today. That’s the future of desktop computers running the Windows or Mac operating system. If Microsoft is still selling an operating system named “Windows” in a couple decades, I bet it will resemble Windows 7 about as much as Windows looks like MS-DOS (Microsoft’s first operating system, for those of you who didn’t use computers 20+ years ago).
To be clear, I’m not predicting that products from Apple will dominate all computing in the next 10-20 years. The computers we use are going to change radically, but it’s too early to predict with certainty which company will sell most of them to us.
I am predicting that keyboard & mouse based operating systems, like Windows and OS X (or their successors), will gradually become more rare, like typewriters. Of course, some tasks will still be better done with ol’ skool tools. Some of us will need a more complicated interface to do what we do. Just as many businesses and some individuals need trucks; but most people drive a car.
And most of us learn to drive a car first, before a few of us learn to drive an 18-wheeler. Which is why I say, if you want your young child to learn to drive the computer of tomorrow, today, you give them an iPad. It has redefined what personal computing feels like, and more closely resembles the future than any other device yet available.
All these thoughts stem from a conversation with Glenn Tucker, last night, about his (cute!) 3 year old. And from remembering how and when my son first learned to operate a computer (without a mouse, nor a graphical interface) and Nintendo (with complex combinations of button clicks) — and which of those early skills remain relevant two decades later.
BTW, I am predicting that I will be one of those people still using the “typewriter” in 20 years. But most of my non-technical friends will be relieved that they never need to drive a big truck to do their work or manage their life. In fact, they won’t even have to use a stick shift.
If you’re already using QuickBooks for your business accounting, it may interest you to know that Intuit is about to release a new version for Mac (as others have reported).
It’s too soon to see actual reviews of this application, but I haven’t heard anything about Intuit fixing the biggest problem with QuickBooks: lock in. QuickBooks provides no real export option for your data. QuickBooks doesn’t even share data between its Mac and Windows versions! This means that when your business accounting needs change in the future, switching to better tools is going to be very difficult and time consuming. This is exactly the kind of automation that computers should do better than humans; but Intuit forces you to do it manually. (Alternately, you could hire a geek, like me, to create a customized export tool for you; but this gets expensive.)
However, those of you already locked into QuickBooks might want to upgrade to a more comfortable cage, when this new version comes out in a few weeks. You’ll need a relatively new Mac running the current (Lion 10.7) or previous (Snow Leopard 10.6.7) version of Mac OS X.
