If we had the same crazy patent environment when cars were being developed, every car would have a different way to control it. Patents should protect true invention for a relatively short period of time to allow the inventor to capitalize on his work. Now they are just barriers to keep the markets closed. Big companies cross license patents to keep their monopolies.

Their hybrid nature does not affect data recovery. All the onboard SSD does is cache data that exists on the HDD.

There is no way to know what will happen to the overall usability of the drive if the flash fails (either through normal write exhaustion or catastrophic failure).

Hopefully, Seagate did the right thing in this case and the drive would turn into the equivalent of a pure mechanical drive. But, failure of the flash or its controller might cause the drive to become completely unusable. Unless they specifically deal with this as a "special" failure mode, it wouldn't be that different from some essential part of the controller on a purely mechanical drive failing (like the DRAM cache), and that usually turns the drive into a doorstop.

A small point. The flash cache is not critical to the operation of the drive. The DRAM on a drive is used for executing firmware, in addition to acting as buffer space, and is therefore critical to the operation of the drive. DRAM failure creates a brick because it can't run the firmware.

Why Time Flies By As You Get Older 252

Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age.

Surgeon Makes Tutorial DVD For Conscious Open-Heart Surgery 170

Lanxon writes "Swaroup Anand, 23, from Bangalore, was fully conscious as he underwent open-heart surgery. An epidural to the neck, administered at the city’s Wockhardt Hospital, numbed his body during the procedure. Dr Vivek Jawali pioneered the technique ten years ago and has recently released a tutorial on DVD, which gives a step-by-step guide to the procedure for other surgeons to watch and learn from."

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."
