Check Out the Source Code For the Xerox Alto

Slashdot - Wed, 29/10/2014 - 9:50pm
jfruh writes The Xerox Alto is a computer legend: it was never sold to the public, but its window-based OS was the inspiration for both the original Mac operating system and Windows. Now you can check out its source code, along with code for CP/M, a similarly old school (though not graphical) operating system.

HP Unveils Industrial 3D Printer 10X Faster, 50% Cheaper Than Current Systems

Slashdot - Wed, 29/10/2014 - 9:30pm
Lucas123 writes HP today announced an 3D industrial printer that it said will be half the cost of current additive manufacturing systems while also 10 times faster, enabling production parts to be built. The company also announced Sprout, a new immersive computing platform that combines a 23-in touch screen monitor and horizontal capacitive touch mat with a scanner, depth sensor, hi-res camera, and projector in a single desktop device. HP's Multi Jet Fusion printer will be offered to beta customers early next year and is expected to be generally available in 2016. The machine uses a print bar with 30,000 nozzles spraying 350 million drops a second of thermoplastic or other materials onto a print platform. The Multi Jet Fusion printer uses fused deposition modeling, an additive manufacturing technology first invented in 1990. the printer works by first laying down a layer of powder material across a build area. Then a fusing agent is selectively applied with the page-wide print bar. Then the same print bar applies a detailing agent at the parts edge to give high definition. The material is then exposed to an energy source that fuses it.

Power and Free Broadband To the People

NewYorkCountryLawyer writes Slashdot member and open source developer Ben Kallos @KallosEsq — who is now a NYC Councilman — is pushing to make it a precondition to Comcast's merging with Time Warner that it agree to provide free broadband to all public housing residents in the City (and by free I mean free as in beer). Kallos, along with NY's Public Advocate, Letitia James, is leading a group of state and local politicians calling on Comcast to help bridge the digital divide in NY.

What Science Lost in the Antares Rocket Explosion

Wired News - Wed, 29/10/2014 - 8:42pm

Last night, an unmanned Antares rocket carrying more than 5,000 pounds of cargo to the International Space Station exploded in a huge fireball seconds after liftoff. No one was hurt, but in addition to damage to the launch pad, NASA lost tons of supplies, including equipment and food for astronauts. Science also took a big hit in the explosion.

Remote Vision Through a Virtual Reality Headset (Video)

Slashdot - Wed, 29/10/2014 - 8:04pm
Add some material-handling devices and you'd have software-controlled Waldos, first described by Robert A. Heinlein in the 1942 short story titled Waldo. So while the idea of a pair of artificial eyes you control by moving your head (while looking at the area around the artificial eyes, even if it's in orbit), sounds like futuristic fun, especially if you use an Oculus Virtual Reality device instead of an LED screen, it not only hasn't caught up with science fiction, but is a fair ways behind science fact. Still, the idea of being able to control a vision system deep under the sea or in orbit around Saturn is certainly interesting in and of itself. (Alternate Video Link)

Beyond Disruption: The Age of the Impact Entrepreneur

Wired News - Wed, 29/10/2014 - 7:23pm

In Mike Judge’s excellent comedy series “Silicon Valley”, the much clichéd mission statement of start-ups claiming “to make the world a better place” is mocked to full effect. In one episode, a handful of start-ups line up to pitch to a panel of investors. They all conclude their presentations with the same lofty ambition, pledging […]

Is the Outrage Over the FBI's Seattle Times Tactics a Knee-Jerk Reaction?

Slashdot - Wed, 29/10/2014 - 7:23pm
reifman writes The Internet's been abuzz the past 48 hours about reports the FBI distributed malware via a fake Seattle Times news website. What the agency actually did is more of an example of smart, precise law enforcement tactics. Is the outrage online an indictment of Twitter's tendency towards uninformed, knee-jerk reactions? In this age of unwarranted, unconstitutional blanket data collection by the NSA, the FBI's tactics from 2007 seem refreshing for their precision.
