CoinVault and Bitcryptor Ransomware Victims Can Now Recover Their Files For Free

itwbennett writes: Researchers from Kaspersky Lab and the Dutch Public Prosecution Service have obtained the last set of encryption keys from command-and-control servers that were used by CoinVault and Bitcryptor, ‘ writes Lucian Constantin. ‘Those keys have been uploaded to Kaspersky’s ransomware decrypt or service that was originally set up in April with a set of around 750 keys recovered from servers hosted in the Netherlands.

Cassini gets cozy with Saturn’s moon, flies 30 miles above its surface

Cassini has just finished the second of three planned Enceladus flybys on October 28th, going as close at 30 miles above the surface of the icy moon’s south polar region. The photo above was taken after the flyby, showing both the moon and Saturn’s rings, but rest assured the probe took a lot of close-up photos. It even grabbed some of the gas and dust that erupted from one of Enceladus’ geysers that typically spew water and other materials up to 125 miles into the sky. NASA will analyze those samples within the next few weeks, which should gives us more details about the composition of the moon’s ocean floor, as well as about any underwater hydrothermal activity. Cassini made the first flyby this early October to take a closer look at Enceladus’ north pole region. It’s scheduled to make its last one on December 19th to measure the heat the moon gives of, after which it’ll move on to other things for the last two years of its life. Source: NASA

Here’s Why Perfectly-Timed Synthesized Music Can Sound Slightly Wrong

Music, if it is to be perfect, can’t be perfectly timed. A perfectly timed musical composition may sound mistimed to our stupid human brains, especially if it’s synthesized. Read more…

Immersion Cooling Drives Server Power Densities To Insane New Heights

1sockchuck writes: By immersing IT equipment in liquid coolant, a new data center is reaching extreme power densities of 250 kW per enclosure. At 40 megawatts, the data center is also taking immersion cooling to an entirely new scale, building on a much smaller proof-of-concept from a Hong Kong skyscraper. The facility is being built by Bitcoin specialist BitFury and reflects how the harsh economics of industrial mining have prompted cryptocurrency firms to focus on data center design to cut costs and boost power. But this type of radical energy efficiency may soon be key to America’s effort to build an exascale computer and the increasingly extreme data-crunching requirements for cloud and analytics.

The first drawings of neurons

In 1837, Italian physician Camilo Golgi devised a reaction to stain the wispy dendrites and axons of neurons, making it possible to see brain cells in situ . In 1875, he published his first scientific drawing made possibly by his chemical reaction, seen here. It’s an illustration of the never fibers, gray matter, and other components of a dog’s olfactory bulb. ” The First Neuron Drawings, 1870s ” (The Scientist)

Functioning Hoverboard Unveiled

An anonymous reader writes: Last year, a company called Arx Pax set up a Kickstarter campaign to develop a functioning hoverboard. Now, the company has demonstrated an updated version of the device, which is fully capable of hovering over a surface made out of conductive metal (video on YouTube). CEO Greg Henderson said, “The hover engine creates a primary magnetic field which is then put over a candidate surface like aluminum or copper. The hover engine then creates swirls of electricity and those create a secondary magnetic field, which propels the firsts.” The device is expensive; Arx Pax is delivering a handful of units to Kickstarter backers who contributed $10, 000. It’s out of the reach of typical consumers, but it does seem to work. Plus, the company is sharing their magnetic field technology with teams taking part in the competition to build pods for a prototype of Elon Musk’s Hyperloop vacuum tube transportation system.

Engineers Create the Blackest Material Yet

schwit1 writes: Researchers have created the least reflective material ever made, using as inspiration the scales on the all-white cyphochilus beetle. The result was an extremely tiny nanoparticle rod resting on an equally tiny nanoparticle sphere (30 nm diameter) which was able to absorb approximately 98 to 99 percent of the light in the spectrum between 400 and 1, 400nm, which meant it was able to absorb approximately 26 percent more light than any other known material — and it does so from all angles and polarizations.

Apple Faces Class Action Lawsuit Over iOS Wi-Fi Assist

An anonymous reader writes: A class-action suit has been filed against Apple in U.S. District Court over Wi-Fi Assist being turned on by default in iOS 9. Wi-Fi Assist is designed to switch to cellular data when a user is trying to perform an action over the internet on a poor Wi-Fi signal. This has the natural side effect of using cellular data. Since iOS 9 turned it on for many users, they weren’t necessarily expecting that extra use, causing some of them to exceed their data caps. A former Apple employee who was in a leadership position for Mac OS X Wi-Fi software has commented on the issue, saying that the Wi-Fi Assist mess was unavoidable given how Apple’s management treats that part of the business. Quoting :”[O]ne particular directorial edict which I pushed back against at the end of my tenure sticks out as not just particularly telling, but deeply misguided: ‘Make it self-healing.’ Self healing in this context meaning that the networking system, Wi-Fi in particular, should try to correct problems that caused the network to fail, which, if you have spent any time trying to diagnose networking issues is a clear misunderstanding of the issues involved. … Asking the devices which connect to this vast complex network of networks to detect, and then transparently fix problems in the infrastructure without the permission of the administrators is, well, it’s absolutely the pinnacle of buzzword driven product management. Real pointy-haired boss territory.” Read more of this story at Slashdot.

Patricia, Strongest Hurricane Ever Seen In Eastern Pacific, Strikes In Mexico

CNN reports that Hurricane Patricia has made landfall in Mexico; Patricia is notable for having the third-lowest barometer reading ever recorded, and as “the strongest hurricane ever observed in the eastern Pacific or Atlantic oceans.” Slate points out that at one point, “satellite estimates of Patricia’s intensity broke the Dvorak scale, peaking at 8.3 on the 8.0 scale. … In fact, Patricia is now very close to the theoretical maximum strength for a tropical cyclone on planet Earth.” The Weather Channel is tracking the storm’s path, and predicts “catastrophic damage … along a narrow path as the eye slices into the interior of southwest Mexico Friday night.” Here’s a map from the National Weather Service showing Patricia’s track as well as projected path.

Ubuntu 15.10 ‘Wily Werewolf’ Released

LichtSpektren writes: Ubuntu 15.10 “Wily Werewolf” is now released and available, along with its alternative desktop flavors (MATE, Xfce, LXDE, GNOME, KDE, Kylin). This release features Linux 4.2, GCC 5, Python 3.5, and LibreOffice 5. The default version is still using X.org display server and Unity7; Mark Shuttleworth has said that Mir and Unity8 won’t arrive until Ubuntu 16.04 “Xenial Xerus.” Not much has changed beyond package updates, other than replacing the invisible overlay scrollbars in Nautilus with the GNOME 3 scrollbars. Phoronix brings us the only bit of drama regarding this release: Jonathan Riddell, long time overseer of Kubuntu, has resigned with claims that Canonical has “defrauded donors and broke the copyright licenses.” Another reader adds a link to a Q & A session with Riddell.
