Submission + - Beamed Core Antimatter Propulsion: Engine Design and Optimization (arxiv.org)

Ashenkase writes: A conceptual design for beamed core antimatter propulsion is reported, where electrically charged annihilation products directly generate thrust after being deflected and collimated by a magnetic nozzle. Simulations were carried out using the Geant4 (Geometry and tracking) software toolkit released by the CERN accelerator laboratory for Monte Carlo simulation of the interaction of particles with matter and fields. Geant permits a more sophisticated and comprehensive design and optimization of antimatter engines than the software environment for simulations reported by prior researchers. The main finding is that effective exhaust speeds Ve ~ 0.69c (where c is the speed of light) are feasible for charged pions in beamed core propulsion, a major improvement over the Ve ~ 0.33c estimate based on prior simulations.

Submission + - Bill C-11 Committee Review - SOPA-style amendments dropped except Digital Locks (michaelgeist.ca)

Ashenkase writes: Michal Geist reviews what stayed and what was rejected by the Bill C-11 Committee Review. Looks like SOPA-style amendments are dropped except Digital Locks. There is still a chance for Canadians to have their voices heard before third reading:

The Bill C-11 legislative committee concluded its clause-by-clause review yesterday as eight government amendments were added to the bill and all opposition amendments were defeated. The amendments included an expanded enabler provision and some modest tinkering to other elements of the bill. There are still several steps needed before the bill passes including third reading at the House of Commons, Senate review, and ultimately royal assent, but Canadian copyright reform is well on its way to completion before the summer starts.

In the days leading up to the clause-by-clause review, many focused on three key issues: no SOPA-style amendments such as website blocking or warrantless disclosure of information, maintaining the fair dealing balance found in the bill, and amending the digital lock provisions. By that standard, the changes could have been a lot worse. The government expanded the enabler provision, though not as broadly as CIMA requested. Virtually all other copyright lobby demands — website blocking, notice-and-takedown, iPod tax, copyright term extension, disclosure of subscriber information — were rejected. Moreover, the provisions supported by consumer and education groups including user generated content protection, time shifting, format shifting, backup copies, Internet provider liability, and statutory damages reform were left untouched. This represents a major victory for the many Canadians and groups such as Open Media that spoke out on these issues.

Submission + - Microsoft attacks Google privacy with Gmail Man spoof (canada.com)

Ashenkase writes: Meet the Gmail man. He’s a lot like a Canada Post letter carrier, except he’s really, really fast.

There’s one more difference between the Gmail Man and the old-fashioned carrier: the Gmail Man reads your mail.

That’s the message behind a video Microsoft released on Jan. 31. The spoof was originally shared internally at Microsoft but the company released it on YouTube this week following a rift between the two companies over Google’s privacy policy.
