Years ago, I got tired of Windows for numerous reasons which I don’t have the time to elaborate in this post. Eventually, I switched to Linux. It was new, exciting, and the opportunity to learn something entirely different was fascinating to me. When Ubuntu Dapper Drake came along, I went all in. That was my desktop of choice for a very long time.
After each Ubuntu release, I worked hard to get everything working from the flash player, media, and just about every tool that I needed, just to get the desktop to function the way I wanted to. After several years of Ubuntu updates and fixing the desktop, I got tired of it. It was an exercise I really didn’t want to do every six months.
I switched to the Mac OS because it it’s based on BSD, a Unix variant, which is familiar to me. In some ways, I can get still get down and dirty using the Terminal if I wanted to. The Mac OS for the most part, is a very stable environment. And everything worked at get-go. I’ve been a Mac OS user ever since.
When you download a file from a website, they usually come with a 128 bit hash the called MD5 hash. The 32 digit hash is used to check for the integrity of the file to make sure the file hasn’t been altered in any way. So, how do you check MD5 hash on the Mac OS? Open up your Terminal and type the following:
The MD5 command will spit out a 12b bit hash that you can compare it with on a website’s download page. If the hash match, then the file’s integrity is intact. If it doesn’t match, then the file has been altered and compromised. Get rid of it. You never know what’s in it.
Capturing screenshots on the Mac OS is quite easy. You’ll just have to learn the commands. So, without further ado, here are the keyboard shortcuts to get you going.
How to capture an active Window
Command + Shift + 4
To capture an active Window, use the keyboard by holding the Command and Shift keys, and then pressing the number 4. You will see a crosshair with the screen axis numbers next to it. Press Spacebar to select the entire active screen. Click the mouse or the touchpad to capture the screen. If you want to just capture a small section of the active Window, hold and drag the mouse or touchpad, when you see the crosshair with the screen axis numbers when prompted. The screenshot will be automatically added to the desktop.
How to capture an entire screen
Command + Shift + 3
To capture the entire desktop screen, use the keyboard by holding the Command and Shift keys, and pressing the number 3. The screenshot will be automatically added to the desktop.
I was browsing the Apple App Store the other night, and I came across an application called “Kindle” for the Mac. And, it’s free. So, I downloaded the application and installed it. Amazon recently made the “Kindle Apps” available to anyone with a smartphone and a computer. You don’t need a Kindle device.
Kindle Apps will work on the PC, Mac, iPad, iPhone, Android, Blackberry and the Windows 7 phone. If you own a Kindle, you can synch any of the Kindle Apps to work in conjunction with your Kindle device. So, Kindle owners are now able to read the books they’ve purchased, not only in the Kindle devices, but also on their computers and smartphones.
The Kindle app for the Mac comes empty. There are no books. You will need to download the books from Amazon’s website. To download, just click on the “Shop in Kindle Store” link on the top hand right corner of the window. You can purchase thousands of books, including the latest releases, as well as download all the free public domain books that are available.
If you already own a Kindle, you just have to register the application with your Amazon credentials. To synch the books you’ve already purchased, you just login and the application will download all your books. It will also remember the last page you’ve read as well as synch any annotations you have created on your Kindle device.
I downloaded two free books, the Art of War by Sunzi and The Adventures of Sherlock Homes by Sir Arthur Conan Doyle. I can see reading on the Kindle can be an expensive hobby. Reading electronically does have it’s distinct advantages. At least, you don’t have to lug around a book everywhere you go.
One million were apps downloaded from the Mac App Store in in just one day. It’s quite impressive. You can add me as one contributor to that statistic. I’ve downloaded a couple of applications in Twitter and TextWrangler. Both were free. The Mac App Store features the top paid and free programs in the store. So, it’s interesting to see which apps are popular. You get a feel for what apps are trending.
Just a couple of applications worth noting.
MindNode for Mac is a elegant mindmapping application for collecting, organizing and outlining your thought and ideas. It’s a perfect tool for brainstorming, holiday planning, research, writing, project management, and meeting notes. The best part of it all is, it’s free. Can’t beat that. I’ve used a mindmapping tool before in my previous work to brainstorm and organize thoughts. I even used it for talks and speeches.
If you’re familiar with HDR images at all, you wonder how it is done. Well, Light Compressor is an app that lets you easily combine multiple exposures into striking HDR images. Light Compressor will combine the images you’ve taken from a tripod and give you the freedom to tweak the color curves, the tone-mapping and saturation before saving it as high quality 16 bit/channel tiff image. This app is practically free for just $0.99.
Well, everyone knows Angry Birds. If you don’t, no worries. Angry Birds is the number one paid app in the Mac App Store. At just $4.99, you can download and play this hugely popular game. Dish out revenge on those green pigs that stole the bird’s eggs. Lots of angry birds here. The game features 195 levels. It’s well worth the price. If you ever need a break from work, go play this game.
