A few weeks back I posted about a new trend in IT called Big Data, and because I like to stay marketable in my chosen field, I’ve started playing around with some Big Data tools. For those looking for a primer on Big Data, the various applications and technologies , and a way to make sense of it all, I can’t recommend enough the Big Data Glossary by Pete Warden from O’Reilly Media.
It’s a small 62 page book, that starts with a terms chapter providing some plain English (or as close as possible) explanations of the lingo that is used throughout the rest of the book. Continue reading
As some background, I’ve been using Adobe Photoshop for several years, since Creative Suite 2 came out (they are up to CS6 now) and I used several other applications from the suite over the years. I didn’t always buy the new versions of the software, sometimes letting one go if the new “features” weren’t enticing enough to fork over the money for them. And recently as my job responsibilities have changed I’ve really only kept Photoshop from the Suite.
Last year, Adobe announced a subscription based software model called the Creative Cloud, that allowed you to essentially rent their various applications on an annual or month-to-month basis. You could rent the entire suite, one application, or a mixture of them. It was an interesting idea, and I could see the benefits to Adobe (less piracy, more even revenue stream). Continue reading
I don’t remember who I originally heard it from, but the advice was don’t delete any pictures after you download and make an intial pass through them. During that first pass, you delete the obvious problem ones – unfocused, blurry, pictures of your thumb, anything you are not going to be able to fix. But after that, before you do any post processing, burn them to a CD or save them to a hard drive, so you have the original. The picture here is a good reason for that.
This image is from Luna Pier, MI and was taken at sunrise, on a late winter/early spring morning about 5 years ago. I liked the colors, and the silhoutted bench was a nice element. But there was a huge light pole on the one side, and several other short poles along the foreground by the bench. (Not sure what they are for, unless its to keep someone from driving their car into Lake Erie?). Anyway, I saved the image and didn’t think any more about it. Technically there was nothing wrong with it, but the distracting elements kept me from being able to use it for anything.
For any one wondering when I was going to do some more photography posts, here is one.
This car has been parked in a vacant lot for a few weeks on my route to work with a for sale sign on it, but the weather hasn’t cooperated with me getting some shots. Saturday the weather was gorgeous (sunny, with a few clouds), so I grabbed my camera and headed out to where it was at. I was hoping to get a few HDR images of the interior of the car, but sadly its in worse than rough shape. The front seat is full of holes, with a big piece of cardboard over one spot, the back seat is full of trash.
I was happy with this shot I got of the front hood ornament though, and the baby blue paint job must have been something to see when it was new….
In the IT world over the past few years there has been a lot of talk / discussion / consternation / anticipation about the concept of “BIG DATA”. (You have to put it in quotes and all caps). If you don’t work or live with the technology sector, it may have passed you by, but lately its started to seep into the mainstream consciousness. Like many fashionable terms, what exactly is meant isn’t often relayed. Its just assumed that people know. After all, its the next big thing. You should already know what it is.
Its been stated in many articles I’ve seen that greater than 80% of the world’s data has been created in the past couple of years. While that certainly sounds impressive, lets look a little closer at “data”. Continue reading
If you are using Ubuntu, you are probably familiar with the concept of repositories – Internet software archives where additional software packages are available to be installed. There are official repositories, supported by Canonical but other vendors and publishers also provide software in their own repositories. Configuration information for accessing these archives is stored in a file at: /etc/apt/sources.list.
To add additional repositories to this file, and be able to install software from them, Continue reading
