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...

With the release of NetNewsWire 4 Public Beta, we wanted to overhaul and modernize NetNewsWire’s app icon as much as the rest of the app. We didn’t throw out everything — the color scheme and satellite metaphor stayed — but the design is completely new.

John Wilkes says that joining Google was like swallowing the red pill in The Matrix. Four years ago, Wilkes knew Google only from the outside. He was among the millions whose daily lives so deeply depend on things like Google Search and Gmail and Google Maps. But then he joined the engineering team at the very heart of Google’s online empire, the team of big thinkers who design the...

A Juniper study finds that mobile malware has grown 600%, and targets Android devices 9:1 vs iOS.

Scala seems to be one of those languages with deep, powerful abstractions and an ever-expanding toolbox. It lures you in with simple, borderline magical examples, and then keeps you engaged by revealing something new and intellectually delicious at every step. The learning curve can be steep, but it’s ultimately rewarding. When you move past “hello worlds” and simple web...
