With everything from refrigerators to thermostats to cars becoming more connected and complex, ARM unveils a chip with twice the processing power of its current champ.

Your washing machine is getting brainier.

Appliances and cars are gaining more intricate touchscreen displays, adding detailed controls and connecting to the Internet. Those features need more computing brainpower, which chip designer ARM hopes to provide with a new processor architecture it unveiled Tuesday called the Cortex-M7.

ARM — a Cambridge, UK-based company that designs the chips found in most smartphones — also sells blueprints for processors that embed in devices including watches, smart meters, refrigerators and thermostats. Under this Cortex-M line, the smallest design is the M0, which when built out can fit within a dimple of a golfball. Read more

f you want to really change the world, Ray Ozzie has concluded, change the conversation. In this case, change it into a medium in which wireless speech becomes a durable, searchable part of the computer world.

Mr. Ozzie, a well-regarded software engineer who in 2010 resigned as Microsoft’s chief software architect, on Tuesday announced a company and product called Talko. An app on the iPhone (and eventually Android phones and desktop computers), Talko enables one-on-one and group calls that can be recorded, tagged, amended and augmented with photos, all while the call is going on.

Later, parts of it can be searched for important elements, such as when a project is due.

Earlier this year, several producers at CNN received an alert from a new digital news gathering tool that they were testing: A teenager in Los Angeles had posted a tweet saying that the pop music heartthrob Justin Bieber had been arrested.

CNN’s Los Angeles bureau followed up on the tip by calling the appropriate local precinct. The police confirmed that Mr. Bieber had just been arrested on burglary charges, but wanted to know how the cable news network could possibly have known that. Read more

The hubs of advanced manufacturing will be the economic drivers of the future because innovation increasingly depends on production expertise.

Visitors to the Crosspointe Rolls-Royce facility in Prince George County, Virginia, have to don safety glasses and steel-tipped shoes, just as they would at any traditional factory. But then things start to look different. Past the cubicles filled with programmers and support staff sits a 140,000-square-foot factory with spotless white concrete floors, bright lighting, surprisingly quiet equipment, and very few human beings.

The municipal identification cards that New York plans to start issuing next year in an effort to make life easier for undocumented immigrants will come with an added benefit so enticing that many others may sign up for them too: an offer of free tickets or discounts at 33 of the city’s leading cultural institutions.

Lincoln Center and Carnegie Hall; the Bronx Zoo and the New York Botanical Garden; the American Museum of Natural History, the Snug Harbor Cultural Center and many others will offer a variety of perks — most of them equivalent to a basic one-year membership — to holders of the new ID cards, which are expected to be made available to any city resident over age 14, regardless of their legal status.

Like many clinics nationwide, my surgery office recently started using electronic medical records. Headaches and glitches abound, but over all, it has been a godsend: no more lost forms, deciphering lousy handwriting or waiting endlessly for someone to “pull the chart” if you want to look up a patient. Everything’s in one centralized computer system, accessible anywhere.

This brave new world, however, has created a singularly embarrassing moment at the end of all my new patient encounters. After saying hello, performing a history and physical examination, talking over the details of surgery and answering questions, I fire up the computer and start entering orders and preparing an after-visit summary for the patient to take home.
