Pulled PSP titles restored to the Vita, security holes covered with tape
Seething about the removal of Everybody's Tennis or Motorstorm: Arctic Edge from the PlayStation Store? Relax, Sony's restored both PSP-titles in time for you to play 'em all through the weekend. Of course, both are now neutered (along with the Vita's firmware) so they can't be used to load arch-hacker Wololo's Vita Half-Byte Loader -- but it hardly matters, they've already got another top-secret exploit ready to launch on an unsuspecting world.

Cassini finds Titan lake is like a Namibia mudflat
ScienceDaily (Apr. 20, 2012) ? A new study analyzing data from NASA's Cassini spacecraft suggests that the lake, known as Ontario Lacus, behaves most similarly to what we call a salt pan on Earth.
A group led by Thomas Cornet of the Universit? de Nantes, France, a Cassini associate, found evidence for long-standing channels etched into the lake bed within the southern boundary of the depression. This suggests that Ontario Lacus, previously thought to be completely filled with liquid hydrocarbons, could actually be a depression that drains and refills from below, exposing liquid areas ringed by materials like saturated sand or mudflats.
"We conclude that the solid floor of Ontario Lacus is most probably exposed in those areas," said Cornet, whose paper appears in a recent issue of the journal Icarus.
These characteristics make Ontario Lacus very similar to the Etosha salt pan on Earth, which is a lake bed that fills with a shallow layer of water from groundwater levels that rise during the rainy season. This layer then evaporates and leaves sediments like tide marks showing the previous extent of the water.
"Some of the things we see happening in our own backyard are right there on Titan to study and learn from," said Bonnie Buratti, a co-author and Cassini team member based at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "On Earth, salt pans tend to form in deserts where liquids can suddenly accumulate, so it appears the same thing is happening on Titan."
While the liquid on Titan is methane, ethane and propane rather than water, the cycle appears to work in a very similar fashion to the water cycle on Earth. Beyond Earth, Titan is the only other world known to bear stable liquids on its surface. There, the full hydrocarbon cycle is based on hydrogen, carbon and nitrogen, and takes place between the atmosphere, the surface and the subsurface. Titan's lakes are an integral part of this process.
This latest paper is part of an ongoing study of Ontario Lacus, the largest lake in Titan's south polar region. Cassini has been observing the lake with multiple instruments and employing multiple methods of analysis to see if Titan, like Earth, changes with the seasons. During the time Cassini has been exploring the Saturn system, Titan's southern hemisphere has transitioned from summer to fall.
"These results emphasize the importance of comparative planetology in modern planetary sciences: finding familiar geological features on alien worlds like Titan allows us to test the theories explaining their formation," said Nicolas Altobelli, ESA's Cassini-Huygens project scientist.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and ASI, the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter was designed, developed and assembled at JPL. The RADAR instrument was built by JPL and the Italian Space Agency, working with team members from the US and several European countries. JPL is a division of the California Institute of Technology in Pasadena.

Londoners mourn as teletext goes dark, a victim of the DTV transition
Despite the many advantages of digital broadcast television, the transition is separating Europeans from a reliable source of information known as teletext. Citizens of London are the latest to experience the loss, as analog signals in the region were switched off just yesterday. Ceefax, a service of the BBC, has provided millions of Britons with news, sports, weather, television listings, subtitles and games for the past 38 years, and is now accessible only in Kent, Sussex, north-east England and Northern Ireland. Soon, it may cease to exist altogether.
Seen as a precursor to the internet, teletext is a free service that's heavily rooted in analog PAL signals, where small packets of data are sent in the vertical blanking interval, which is otherwise unnoticed by viewers. Because the information is broadcast, users were never subject to network congestion, and only needed to wait a brief moment for their desired page to be transmitted -- more advanced televisions even cached this information locally. As part of the airwaves, the service is naturally free, and in that sense, it lacks a suitable replacement. As with all progress, however, there are casualties, and teletext was an unfortunate bystander. Those who cherished the service can take a moment to relive the memories in the links below.
