Lunar eclips and impact already happend, 3D printed space food (not), Yahoo buys Tumblr, two factor authentication, BitTorrent Sync, and much, much more.
Lunar eclipses can only occur when the moon is on the opposite side of the Earth from the sun, which occurs during the full moon phase. When the moon is perfectly aligned with the Earth, it is completely in the Earth’s shadow, causing a total lunar eclipse that can yield amazing views of a blood-red moon. However, the moon’s orbit is tilted, so it does not line up perfectly each month. When the moon only passes through part of the Earth’s shadow, it causes a partial lunar eclipse. A dip through the outer edges of the shadow, like tonight’s eclipse, is a penumbral lunar eclipse.
For the past 8 years, NASA astronomers have been monitoring the Moon for signs of explosions caused by meteoroids hitting the lunar surface. “Lunar meteor showers” have turned out to be more common than anyone expected, with hundreds of detectable impacts occurring every year.
They’ve just seen the biggest explosion in the history of the program.
“On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium,” says Bill Cooke of NASA’s Meteoroid Environment Office. “It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before.”
“… contrary to what many people may think, the U.S. uses the metric system now to define all basic units used in commerce and trade. At the same time, if the metric system and U.S. customary system are languages of measurement, then the United States is truly a bilingual nation. … Ultimately, the use of metric in this country is a choice and we would encourage Americans to continue to make the best choice for themselves and for the purpose at hand and to continue to learn how to move seamlessly between both systems.”
At 3:33 a.m. on May 22, 2013 (just a few hours ago as I write this) in Hawaii, the sky was briefly lit up by a huge expanding bubble of light in the east. I got word of this event from astronomer Adam Draginda, who is a telescope operator at the Canada France Hawaii Telescope, located at the top of Mauna Kea.
An all-sky camera at the observatory monitors the sky for weather, and captured the event:
Pegasus, a small cube weighing just 1.2kg (2.6lb), has been orbiting the Earth at a height of 650km (404 miles), transmitting pictures from space while playing recordings of the Ecuadorean national anthem.

Ask Josh Alexander, CEO of authentication company Toopher, how you’d go about hacking Twitter now that two-factor authentication is in place. He’ll tell you that you do it exactly the same way you did before the advent of two-factor authentication.
In a short, droll video about Twitter’s two-factor authentication, Alexander congratulates Twitter for joining a “security two-step program” and taking the first step, admitting a problem exists. He then goes on to illustrate just how little the SMS-based two-factor authentication helps. “Your new solution leaves the door wide open,” said Alexander, “for the same man-in-the-middle attacks that compromised the reputations of major news sources and celebrities.”
Will blinking blue lights of servers soon fill the aisles that previously offered the Blue Light Special? Sears Holdings has formed a new unit to market space from former Sears and Kmart retail stores as a home for data centers, disaster recovery space and wireless towers.
AT&T has imposed a new “stealth fee” that, starting with this month, will tack an extra 61 cents on their monthly bills. While the amount is small, the principle behind it has many – both customers and non-customers alike – crying foul. The carrier says the new fee is a monthly administrative charge, and says that other carriers have done the same. Though it is a small amount, the company is slated to make millions from it.
BitTorrent Sync synchronizes your files using a peer-to-peer (P2P) protocol. This protocol is very effective for transferring large files across multiple devices, and is very similar to the powerful protocol used by applications like µTorrent and BitTorrent. The data is transferred in pieces from each of the syncing devices, and BitTorrent Sync chooses the optimal algorithm to make sure you have a maximum download and upload speed during the process.
The devices you setup to sync are connected directly using UDP, NAT traversal and UPnP port mapping. We also provide such additional methods of ensuring connectivity as relay and tracker servers. If your devices are on the same local network, BitTorrent Sync will use your LAN for faster synchronization.
