The Wrong Abstraction

Shared by

Don’t get trapped by the sunk cost fallacy. If you find yourself passing parameters and adding conditional paths through shared code, the abstraction is incorrect. It may have been right to begin with, but that day has passed.

Schemas for the Real World

Shared by

Social app development challenges us to code for users’ personal world. Users are giving push-back to ill-fitted assumptions about their own identity - name, gender, sexual orientation, important relationships, and many other attributes that are individually meaningful.

Obama’s secret struggle to retaliate against Putin’s election interference

Shared by

Homeland Security Secretary Jeh Johnson’s efforts to secure the U.S. voting systems run aground when some state officials reject his plan, calling it a federal takeover.

Q: What is the Most Feminist Thing Your Dad has Said or Done?

The pastor, a man in his mid thirties, was probably not quite ready for what my Dad, in his early sixties, was going to say.

Errata Security: How The Intercept Outed Reality Winner

Shared by

Most printers print nearly invisibly yellow dots that track down exactly when and where documents, any document, is printed. Because the NSA logs all printing jobs on its printers, it can use this to match up precisely who printed the document.

Seeing Theory - A visual introduction to probability and statistics

Shared by

Seeing Theory is a project designed and created by Daniel Kunin with support from Brown University’s Royce Fellowship Program. The goal of the project is to make statistics more accessible to a wider range of students through interactive visualizations. Seeing Theory visualizes the fundamental concepts covered in an introductory college statistics or Advanced Placement statistics class. Students are encouraged to use Seeing Theory as an additional resource to their textbook, professor and peers.

Cassini Finds Saturn Moon May Have Tipped Over

Shared by

Whether it was caused by an impact or some other process, Tajeddine and colleagues think the disruption and creation of the tiger-stripe terrain caused some of Enceladus’ mass to be redistributed, making the moon’s rotation unsteady and wobbly. The rotation would have eventually stabilized, likely taking more than a million years. By the time the rotation settled down, the north-south axis would have reoriented to pass through different points on the surface – a mechanism researchers call “true polar wander.”

A Whole New Jupiter: First Science Results from NASA’s Juno Mission

Shared by

“Every 53 days, we go screaming by Jupiter, get doused by a fire hose of Jovian science, and there is always something new,” said Bolton. “On our next flyby on July 11, we will fly directly over one of the most iconic features in the entire solar system – one that every school kid knows – Jupiter’s Great Red Spot. If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it’s Juno and her cloud-piercing science instruments.”

Saturn’s Rings: The Cassini Division, Huygens Gap, A-ring, B-ring—and PHYSICS!

So the B-ring is a dense place with a mass nearly the same as Saturn’s moon Mimas (yup, our solar system’s very own death star).

Undercover restorers fix Paris landmark's clock

For a year from September 2005, under the nose of the Panthéon’s unsuspecting security officials, a group of intrepid “illegal restorers” set up a secret workshop and lounge in a cavity under the building’s famous dome.

These scientists made 2,879 tiny clay caterpillars and hid them all over the world

Shared by

The fake caterpillars revealed that, indeed, predation is highest near the equator and lowest near the poles; for every 1 degree of latitude north or south of the equator, the odds of a caterpillar getting attacked decreased by 2.7 percent. So a caterpillar in Zackenberg, Greenland was about 87 percent less likely to get bitten than a caterpillar at the equator.

Open-Plan Offices Kill Productivity

Shared by

Enclosed private offices clearly outperformed open-plan layouts in most aspects of IEQ (Indoor Environmental Quality), particularly in acoustics, privacy and the proxemics issues. Benefits of enhanced ’ease of interaction’ were smaller than the penalties of increased noise level and decreased privacy resulting from open-plan office configuration.

Time lapse of a cloud inversion filling the Grand Canyon with an undulating vaporous ocean

Shared by

Usually, the air nearest the Earth is the warmest and it gets cooler as the altitude increases. But sometimes, there’s a meteorological inversion and colder air gets trapped near the ground with a layer of warmer air on top. While working on a dark sky project, Harun Mehmedinovic shot a time lapse movie of a rare cloud inversion in the Grand Canyon, in which the entire canyon is filled nearly to the brim with fluffy clouds.

Deep Neural Networks are Easily Fooled: High Confidence Predictions for Unrecognizable Images

Shared by

That DNNs see these objects as near-perfect examples of recognizable images sheds light on remaining differences between the way DNNs and humans recognize objects, raising questions about the true generalization capabilities of DNNs and the potential for costly exploits of solutions that use DNNs.

If Americans Can Find North Korea on a Map, They’re More Likely to Prefer Diplomacy

Shared by

On average, Republicans – and Republican men in particular – were more likely to correctly locate North Korea than Democratic men. And Republicans were more likely to be in favor of almost all the diplomatic solutions posed by the researchers. (Women tended to find North Korea at similar rates, regardless of party.)
