What to consider when parsing through your Parse alternatives

by GILLES GUIRAND — 6 weeks ago in CONTRIBUTORS Credit: Parse At the conclusion of January, Facebook had officially shuttered Parse, disabling the API on an app by app basis. As a Backend as a Service (BaaS) product, the development platform provided SDKs and APIs that allowed developers to quickly build their apps without having to build a backend from scratch. Facebook did’t present much insight into the motivation to shut down the platform. But Parse’s customers, following the 2013 acquisition, comprised heavily of small to medium sized developers that had aRead More

If Buddhist Monks Trained AI

Monks take on the trolley problem, a classic moral dilemma that has big implications for driverless cars. A Buddhist monk with a robot monk developed by a temple BeijingKim Kyung Hoon / Reuters The Harvard psychologist Joshua Greene is an expert in “trolleyology,” the self-effacing way he describes his research into the manifold variations on the “trolley problem.” The basic form of this problem is simple: There’s a trolley barreling towards five people, who will die if they’re hit. But you could switch the trolley onto another track on which onlyRead More

  Difference Engine 3. (click for larger image) (note:detail theory here, http://robroy.dyndns.info/collier/ch3.html) History Before the day of computers and pocket calculators all mathematics was done by hand. Great effort was expended to compose trigonometric and logarithmic tables for navigation, scientific investigation, and engineering purposes. The larger efforts involved rooms of semi skilled people, called ‘computers’, capable of doing reliable arithmetic who would be under the direction of a skilled mathematician. In the mid-19th century, people began to design machines to automate this error prone process. Many machines of various designsRead More

Up and Down the Ladder of Abstraction

In science, if you know what you are doing, you should not be doing it. In engineering, if you do not know what you are doing, you should not be doing it. Of course, you seldom, if ever, see either pure state.” —Richard Hamming, The Art of Doing Science and Engineering How can we design systems when we don’t know what we’re doing? The most exciting engineering challenges lie on the boundary of theory and the unknown. Not so unknown that they’re hopeless, but not enough theory to predict theRead More

Mars Pathfinder Debug

From: Mike Jones <mbj@microsoft.com> Sent: Sunday, December 07, 1997 6:47 PM Subject: What really happened on Mars? The Mars Pathfinder mission was widely proclaimed as “flawless” in the early days after its July 4th, 1997 landing on the Martian surface. Successes included its unconventional “landing” — bouncing onto the Martian surface surrounded by airbags, deploying the Sojourner rover, and gathering and transmitting voluminous data back to Earth, including the panoramic pictures that were such a hit on the Web. But a few days into the mission, not long after PathfinderRead More
