Use the ‘Eisenhower Box’ to Stop Wasting Time and Be More Productive

It is interesting to know the brief history of the “Eisenhower Box”. However, the author missed the most important aspect of the box. That is, contrary to what the author said, the region of “Not Urgent” and “Important” actually is the most important region, because most non-urgent and important tasks, if not handled in time, always turn into urgent and important tasks. What people spend in the urgent and important region actually is fire fighting, which should be avoided at all cost. Ultimately, people should spend around 80% of daily effort on the non-urgent but important tasks to prevent future fire fighting. This would truly make you productive than others.

A Ranking Of The Deadliest Animals In The World

What animal is the most dangerous to humans in the world? Is it snakes? No. Sharks? Not even close. Other humans? Getting warmer, but not quite.

It’s the mosquito. Bill Gates posted this graphic, which uses data from the WHO and the FAO, on his blog, charting out which animal kills the most humans a year. So, how did the little mosquito become so deadly? The issue isn’t the bite itself, it’s the diseases that can come with it, especially malaria.

9 Free Books for Learning Data Mining and Data Analysis

There is still no shortcut to learn data mining except for learning statistics. But, people are still writing e-books to entertain the popular topic.

Carnegie Mellon System Lets iPad Users Explore Data With Their Fingers

Called Kinetica, this proof-of-concept system for the Apple iPad converts tabular data, such as Excel spreadsheets, so that data points appear as colored spheres on the touchscreen. People can directly manipulate this data, using natural gestures to sort, filter, stack, flick and pull data points as needed to help them answer questions or explore hidden relationships.

NYT uses R to forecast Senate elections

Nate Silver’s departure to relaunch left a bit of a hole at the New York Times, which The Upshot — the new data journalism practice at the Times — seeks to fill. And they’ve gotten off to a great start with the new Senate forecasting model, called Leo. Leo was created by Amanda Cox (longtime graphics editor at the NYT) and Josh Katz (creator of the Dialect Quiz), and uses a similar poll-aggregation methodology to that used by Silver. The model itself is implemented in the R language, and the R code is available for inspection at GitHub.

The way we board airplanes makes absolutely no sense

Most US airlines follow the same procedure for allowing non-first-class passengers to board a plane. They let people who are sitting in the back board first, then people in the next few rows, gradually working their way toward the front.

This procedure makes absolutely no sense.

“The Data shows this is not a good way to board an airplane”

If asked to devise a boarding method without any data, you might settle on this as a pretty sensible one. But the airlines do have data — and numerous studies have shown this is not a good way to board an airplane, in terms of time or customer satisfaction.

The fastest ways to board a plane are Southwest’s boarding method — where people choose their own seats — or a theoretical boarding method known as the “Steffen method” that’s not currently in use.

Both simulations and real-life experiments have proven the standard method to be the slowest out of several different ones. In 2012, the TV show “Mythbusters” recruited 173 people to compare four methods in a replica airplane interior and found that Southwest’s boarding method was the fastest. A close second was allowing all windows seats to board first, then all middles, then all aisles (outside-in).

This article has a very interesting video illustration.

How Apple dodged the Heartbleed bullet

In 2011, Apple told its developers that it would be deprecating OS X’s Common Data Security Architecture including OpenSSL, describing it as an outdated relic of the late 1990s. Nearly three years later, OpenSSL was hit by a severe flaw that affected a wide swath of vendors and their users, but not Apple.
