Comment Re:Are there still memory leaks? (Score 2) 156

Funny you should say that. I regularly use Firefox and Chrome on two very different machines: one, is an anemic laptop with a Pentium T4200, the other a desktop with 8 cores and lots of memory. On the weaker machine, Chrome is visibly snappier - and never slows down at the end of the day. Firefox seems quite spry in the beginning, but quickly becomes visibly slower - not its rendering, but its general reaction, the awful, XUL-based interface. By the end of the day, right-clicking on a page and/or opening a new tab has a very visible, very annoying lag and the overall reactivity has decreased greatly. It's not a problem induced by some esoteric extensions (I only use Ghostery), I have enough memory (8GB, and the system memory load never goes beyond 50-52%), I only read text (lots of pages, though), no video, no games, flash is disabled via click-to-run. The faster/newer machine exhibits the same behaviour, it only takes a while longer for the lag to be apparent (due, obviously, to the increased computing power). I've always been a supporter of Firefox, I've been using it continuously since the 0.x era (in its Phoenix incarnation), but I'm not blind and statements like "FF is faster than Chrome" simply make no sense to me (and my browsing habits).

Submission + - TSA eliminates all invasive X-ray machines

dsinc writes: The Transportation Security Administration announced it has finished removing from all airports the X-ray technology that produced graphic and controversial images of passengers passing through security screening checkpoints.
The machines, which the TSA first deployed in 2008, provoked public outrage as the technology, better able than traditional X-rays to detect hidden contraband, also created images that appeared as if they were "virtual nudes." Critics called this an invasion of privacy and questioned whether the scanning devices truly lacked the ability to save the images, as the TSA claimed.

Submission + - Mathematical breakthrough sets out rules for more effective teleportation (cam.ac.uk)

dsinc writes: Once considered impossible, in 1993 a team of scientists calculated that teleportation could work in principle using quantum laws. Quantum teleportation harnesses the âentanglementâ(TM) law to transmit particle-sized bites of information across potentially vast distances in an instant.

Entanglement involves a pair of quantum particles such as electrons or protons that are intrinsically bound together, retaining synchronisation between the two that holds whether the particles are next to each other or on opposing sides of a galaxy. Through this connection, quantum bits of information â" qubits â" can be relayed using only traditional forms of classical communication.

Previous teleportation protocols have fallen into one of two camps, those that could only send scrambled information requiring correction by the receiver or, more recently, âoeport-basedâ teleportation that doesnâ(TM)t require a correction, but needs an impractical amount of entanglement â" as each object sent would destroy the entangled state.

Now, physicists from Cambridge, University College London, and the University of Gdansk have developed a protocol to provide an optimal solution in which the entangled state is ârecycledâ(TM), so that the gateway between particles holds for the teleportation of multiple objects.

Submission + - Air Force sends mystery mini-shuttle back to space (ap.org)

dsinc writes: The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket.

It's the second flight for this original X-37B spaceplane. It circled the planet for seven months in 2010. A second X-37B spacecraft spent more than a year in orbit.

These high-tech mystery machines — 29 feet long — are about one-quarter the size of NASA's old space shuttles and can land automatically on a runway. The two previous touchdowns occurred in Southern California; this one might end on NASA's three-mile-long runway once reserved for the space agency's shuttles.

The military isn't saying much if anything about this new secret mission. In fact, launch commentary ended 17 minutes into the flight.

But one scientific observer, Harvard University's Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, speculates the spaceplane is carrying sensors designed for spying and likely is serving as a testbed for future satellites.

Submission + - ITU Approves Deep Packet Inspection, Ignores Huge Privacy Implications (techdirt.com)

dsinc writes: Techdirt has run a number of articles about the ITU's World Conference on International Telecommunications (WCIT) currently taking place in Dubai. One of the concerns is that decisions taken there may make the Internet less a medium that can be used to enhance personal freedom than a tool for state surveillance and oppression.
The new Y.2770 standard is entitled "Requirements for deep packet inspection in Next Generation Networks", and seeks to define an international standard for deep packet inspection (DPI). As the Center for Democracy & Technology points out, it is thoroughgoing in its desire to specify technologies that can be used to spy on people.

One of the big issues surrounding WCIT and the ITU has been the lack of transparency — or even understanding what real transparency might be. So it will comes as no surprise that the new DPI standard was negotiated behind closed doors, with no drafts being made available.

Submission + - NASA: Curiosity has found plastic on Mars (nasaupdatecenter.us) 2

dsinc writes: Last week Curiosity was able to use its SAM (Sample Analysis at Mars) device to confirm the discovery. A robotic arm with a complex system of Spectral Analysis devices was able to vaporize and identify gasses from the sample, concluding that it is in fact plastic. How plastic formed or ended up on the Martian surface is quite an exciting mystery that sparks many questions. The type of plastic sampled as we know so far can only be formed using petrochemicals, meaning not only that there could possibly be a source of oil on the Red Planet, but that somehow it got turned into plastic. Even more interesting is that oil or petrochemicals used to create this type of plastic are only known to come from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil pointing to the earthshaking evidence that there was once life on mars.

"Right now we have multiple working hypotheses, and each hypothesis makes certain predictions about things like what the spherules are made of and how they are distributed," said Curiosity's principal investigator, Steve Squyres, of Cornell University, Ithaca, N.Y. "Our job as we explore Matijevic Hill in the months ahead will be to make the observations that will let us test all the hypotheses carefully, and find the one that best fits the observations."

Submission + - Saudi Arabia implements electronic tracking system for women (rawstory.com)

dsinc writes: Denied the right to travel without consent from their male guardians and banned from driving, women in Saudi Arabia are now monitored by an electronic system that tracks any cross-border movements.

Since last week, Saudi women’s male guardians began receiving text messages on their phones informing them when women under their custody leave the country, even if they are travelling together.

“The authorities are using technology to monitor women,” said columnist Badriya al-Bishr, who criticised the “state of slavery under which women are held” in the ultra-conservative kingdom.

Women are not allowed to leave the kingdom without permission from their male guardian, who must give his consent by signing what is known as the “yellow sheet” at the airport or border.
