Using Lasers To Generate Random Numbers Faster 149

Posted by timothy from the just-think-what-a-faster-laser-could-do dept.
Pranav writes "Using semiconductor lasers, scientists from Takushoku University, Saitama University, and NTT Corporation achieved random number rates of up to 1.7 gigabits per second, which is about 10 times higher than the second-best rate, produced using a physical phenomenon. Future work may center on devising laser schemes that can achieving rates as high as 10 Gbps."

Judge Rules Fox Has Copyright Claim To Watchmen 262

Posted by timothy from the there-are-ways-of-telling dept.
fermion writes "According to the NYT, a judge has decided that Fox owns the copyright to Watchmen, not Warner. Is this an example of copyright law becoming so complex that companies can abuse the court system to prevent competition, or just extreme incompetence by Warner? In the current business environment, either explanation is believable. Yet it is unbelievable that seasoned producers would spend hundreds of millions of dollars to create a movie that they can't even release. It seems the judge didn't want to bring this to a jury, and maybe daring Warner to appeal, or Fox to settle." The article says that Fox acquired movie rights to the Watchmen story in the late 1980s, but budget disputes and personnel changes have muddied the waters; Wikipedia has a bit more on the "development hell" which has plagued the film project.

Apple Believes Someone Is Behind Psystar 606

Posted by CmdrTaco from the put-on-your-foil-hats dept.
rgraham writes "From the article on Growler: 'Apple apparently believes that somebody else is behind Psystar, which might help to explain why a major law firm would take on what seems like a fly-by-night's case; also why Psystar has been so bold in continuing to sell its products. I knew this thing felt funny. As Alice in Wonderland might put it, "It gets interestinger and interestinger."'"

Optimizing Linux Use On a USB Flash Drive? 137

Posted by timothy from the right-here-in-my-pocket dept.
Buckbeak writes "I like to carry my Linux systems around with me, on USB flash drives. Typically, SanDisk Cruzers or Kingston HyperX. I encrypt the root partition and boot off the USB stick. Sometimes, the performance leaves something to be desired. I want to be able to do an 'apt-get upgrade' or 'yum update' while surfing but the experience is sometimes painful. What can I do to maximize the performance of Linux while running off of a slow medium? I've turned on 'noatime' in the mount options and I don't use a swap partition. Is there any way to minimize drive I/O or batch it up more? Is there any easy way to run in memory and write everything out when I shut down? I've tried both EXT2 and EXT3 and it doesn't seem to make much difference. Any other suggestions?"
