Newton was conceived on an airplane. That’s where Michael Tchao pitched the idea to Apple’s CEO, John Sculley, in early 1991. The company would announce it the following year, and the first product in the Newton Line, the MessagePad 1001 went on sale twenty years ago this week in August of 1993. It was Apple’s handheld PDA–a term Apple coined to describe it. By modern...

The WigWag system lets you write rules on the "if this, then that" principle. The creators include examples like: If there's motion outdoors, then turn the lights on and send a text. If the humidity rises, then turn on a fan.

A presentation at the Paris Scala meetup about using Scala on "big data" projects.

During the past two years Netflix has pulled back the curtains to provide a behind-the-scenes glimpse into how it runs one of the most popular video streaming websites on the Internet, almost entirely in the public cloud. The company has open sourced dozens of tools it’s developed internally. In doing so, some argue that Netflix is turning into one of the most important cloud computing...

For the past four years, physicists at the National Ignition Facility, or NIF, in Livermore, California, have been trying to harness nuclear fusion, the same reaction that powers the sun and the stars. Supporters of the $3.5 billion facility believe that a successful outcome to the experiments could help usher in an era of nearly limitless energy. But the ambitious fusion research program at...

Each person has a "world view", that is how he sees, represents and understand himself and the world.

a world view evolves as the person learns, unlearns and questions his views
beliefs are a subset of the world view the person holds to be "likely" to be true (that too can change over time)

Despite traveling 36 years and 11 billion miles (18 billion kilometers) from home, the intrepid Voyager 1 spacecraft still has not left the solar neighborhood. But all indications are that it is now crossing a major threshold to the rest of the galaxy. (Related: “Voyager at the Edge: Cosmic Roadtrip Hits Milestone.” )

Value classes are a new mechanism in Scala to avoid allocating runtime objects. This is accomplished through the definition of new AnyVal subclasses. They were proposed in SIP-15. The following shows a very minimal value class definition:

class Wrapper(val underlying: Int) extends AnyVal

It has a single, public val parameter that is the underlying runtime representation. The...

Ahead of tomorrow’s expected announcement and amidst last week’s QCon London conference, InfoQ received an invitation to sit down with Martin Odersky to discuss both Typesafe Stack 2.0 and Scala. In the following interview Martin discusses the future of Scala, draws the comparisons between F# and Scala and addresses, once and for, all the question of breaking binary compatibility.


PASADENA, Calif. -- Data from Voyager 1, now more than 11 billion miles (18 billion kilometers) from the sun, suggest the spacecraft is closer to becoming the first human-made object to reach interstellar space.

Research using Voyager 1 data and published in the journal Science today provides new detail on the last region the spacecraft will cross before it leaves the heliosphere, or...
