A powerful gamma-ray burst may have blasted Earth back in the 8th century, new research has revealed. Scientists discovered a surge in carbon-14 - an isotope that comes from high-energy radiation - in the rings of ancience cedar trees in Japan, suggesting the burst struck Earth in 774 or 775 AD. The wave of cosmic radiation could have potentially come from black holes colliding or the merger of two neutron stars (artist's impression shown).

What is the difference between asynchronous and synchronous execution?

When you execute something synchronously, you wait for it to finish before moving on to another task. When you execute something asynchronously, you can move on to another task before it finishes. That being said, in the context of computers this translates into executing a process or task on another "thread." A thread is a series of commands (a block of code) that exists as a unit of work. The operating system can manage multiple threads and assign a thread a piece ("slice") of processor time before switching to another thread to give it a turn to do some work. At its core (pardon the pun), a processor can simply execute a command, it has no concept of doing two things at one time. The operating system simulates this by allocating slices of time to different threads. Now, if you introduce multiple cores/processors into the mix, then things CAN actually happen at the same time. The operating system can allocate time to one thread on the first processor, then a...

Yahoo accepting requests for inactive email IDs SAN FRANCISCO:  Yahoo  is allowing people to place claims on inactive  email  addresses that are being given a second life.  The opportunity to request the identifications began Monday afternoon and will extend through Aug. 7. Up to five different names can be submitted at http://wishlist.yahoo.com .  Yahoo Inc. says a substantial number of old email IDs are being made available, but isn't providing specifics.  The email IDs are being released a month after the Sunnyvale, California, company notified users that they would have 30 days to log into an inactive account if they wanted to keep it.  People awarded the rights to the recycled email addresses will have a 48-hour period to activate the accounts beginning Aug. 15
