Digital Decluttering: 3 Ways to Visualize Your Mac’s Hard Drive

By:

How to spot RAM offenders, or what data visualization has to do with the workings of your second brain.

Our hard drives are our satellite brains, vital extensions of our intellectual and creative input and output. But our informationally voracious habits also mean that our second brains get inevitably overwhelmed, slowing down and spasming under the weight of our tastes and interests. To combat the issue, here are three fantastic visualization tools — playing on today’s running theme of data visualization — that help declutter your hard drive without requiring any programming knowledge, visually track down what takes the most space and memory, and allowing you to optimize accordingly.

GRAND PERSPECTIVE

GrandPerspective is a Mac OSX utility for graphically showing the file disk usage on your computer using tree map visualizations. It developed by Erwin Bonsma and is released for free as open-source under the GNU General Public License. You can support the project with a donation.

DAISY DISK

DaisyDisk scans your hard drive, as well as any external drives you have mounted, and visualizes the contents as interactive maps, allowing you to easily spot unusually large files and delete or move them to an external hard drive to get more free space. The program’s scanning engine is surprisingly fast even with drives as large as several terabytes. You can get a copy for the rather reasonable $19.99.

DISK INVENTORY X

Disk Inventory X, developed by Tjark Derlien, is very similar to GrandPerspective — same tree map visualizations, also a free download and under a GPL license, also supported by donations — though with a slightly different and more intuitive interface. It was inspired by WinDirStat, the hard drive visualization utility for Windows.

Visualize This: How to Tell Stories with Data

By:

How to turn numbers into stories, or what pattern-recognition has to do with the evolution of journalism.

Data visualization is a frequent fixation around here and, just recently, we looked at 7 essential books that explore the discipline’s capacity for creative storytelling. Today, a highly anticipated new book joins their ranks — Visualize This: The FlowingData Guide to Design, Visualization, and Statistics, penned by Nathan Yau of the fantastic FlowingData blog. (Which also makes this a fine addition to our running list of blog-turned-book success stories.) Yu offers a practical guide to creating data graphics that mean something, that captivate and illuminate and tell stories of what matters — a pinnacle of the discipline’s sensemaking potential in a world of ever-increasing information overload.

And in a culture of equally increasing infographics overload, where we are constantly bombarded with mediocre graphics that lack context and provide little actionable insight, Yau makes a special point of separating the signal from the noise and equipping you with the tools to not only create better data graphics but also be a more educated consumer and critic of the discipline.

From asking the right questions to exploring data through the visual metaphors that make the most sense to seeing data in new ways and gleaning from it the stories that beg to be told, the book offers a brilliant blueprint to practical eloquence in this emerging visual language.

On the book’s companion site, you can find downloadable data files, interactive examples of how visualization works and, if you’re technically inclined, even code samples to use as the basis for your own visual experimentation.

Visually stimulating, intellectually illuminating and creatively compelling, Visualize This: The FlowingData Guide to Design, Visualization, and Statistics is equal parts practical vocabulary for an essential modern language and conceptual testament to the power of data visualization as a new form of journalism and a powerful storytelling medium.

For a historical perspective on infographics, be sure to see the story of Otto Neurath’s Isotype.

Akule: Magnificent Black-and-White Underwater Photographs

By:

What underwater tornadoes have to do with marine sustainability and Captain Cook’s death.

For the past 30 years, photographer Wayne Levin has been capturing the magnificence of the underwater world in spellbinding black-and-white images with equal parts mystery and awe. One day, as he was swimming to photograph the spinner dolphins of Hawaii’s Kealakekua Bay, infamous as the location of Captain Cook’s death, Levin came across what appeared to be a giant coral reef. But, as he approached it, the “reef” began to move and morph, turning out to be an enormous school of bigeyed scad fish. Levin snapped some photos and scurried to find the dolphins, but the experience stuck with him. Over time, he developed a fascination with the strange beauty and synchronicity of these fish schools and spent the next 10 years capturing them on hundreds of rolls of film.

His new book, Akule, offers a selection of his finest photographs, named after the Hawaiian word for bigeyed scads. Haunting and poetic, Levin’s work is particularly fascinating — if not melancholic — when examined in parallel with the Census of Marine Life and our efforts to reverse the damage we’ve inflicted on this whimsical microcosm.

Most underwater photographers are divers first, then they get into photography to capture the beautiful scenes they see underwater. I was a photographer first. My first serious underwater photography was when I finished graduate school at Pratt in 1983. I returned to Hawaii to teach photography at University of Hawaii, and decided to photograph surfers from underwater. My first attempts were in color, but the results were very murky blue on blue. Then I switched to black and white, and everything came alive.” ~ Wayne Levin

I feel a sense of freedom, and I can feel myself relax, and my bodily functions slow down as I leave the anxieties of the human world behind. But the ocean has its own dangers. … So there is a freedom in being underwater, but also a responsibility to always be aware of your surroundings, and yourself.” ~ Wayne Levin

Akule is the follow-up to Wayne’s 1997 debut book, Through a Liquid Mirror, a play on the title of Lewis Carroll’s Through the Looking Glass to convey the magic and wonderment Wayne finds once he passes through the surface, just like Alice passes through the mirror into Wonderland. For more, NPR has an excellent interview with Levin.
