Samsung Unveils First PCIe 3.0 x4-Based M.2 SSD, Delivering Speeds of Over 2GB/s

Slashdot - Thu, 08/01/2015 - 4:05pm
Deathspawner writes: Samsung's SM951 is an unassuming gumstick SSD — it has no skulls or other bling — but it's what's underneath that counts: PCIe 3.0 x4 support. With that support, Samsung is able to boast speeds of 2,150MB/s read and 1,550MB/s write. But with such speeds comes an all-too-common caveat: you'll probably have to upgrade your computer to take true advantage of it. For comparison, Samsung says a Gen 2 PCIe x4 slot will limit the SM951 to just 1,600MB/s and 1,350MB/s (or 130K/100K IOPS), respectively. Perhaps now is a bad time to point out a typical Z97 motherboard only has a PCIe 2nd Gen x2 (yes, x2) connection to its M.2 slot, meaning one would need to halve those figures again.

FCC Favors Net Neutrality

Slashdot - Thu, 08/01/2015 - 3:22pm
dkatana writes: Yesterday, FCC Chairman Tom Wheeler said net neutrality is high on the agency's agenda, and a set of rules will be proposed beginning of next month. He also talked about reclassification of internet providers such as Google Fiber as Title II Telecom Companies. If Google and other fiber providers are given pole access, it could be the beginning of a race to deploy fiber-to-the-home to many cities and towns, where the cost of digging trenches has deterred many initiatives and protected the monopolies of the entrenched telecom providers. Advocates for net neutrality believe that Title II classification would allow the FCC to protect Internet services by regulating against paid prioritization. A related article suggests one side effect of the internet becoming a public utility will be higher costs for internet access.

Regional patterns of soot, dirt on North American snow discovered

Science Daily - Thu, 08/01/2015 - 3:06pm
A first large-scale survey of snow in the US and Canada finds that disturbed soil often darkens the snow as much as air pollution. The new readings complement recent snow surveys in the Arctic and Northern China.

Longest-ever case of sperm storage in sharks documented

Science Daily - Thu, 08/01/2015 - 3:06pm
Biologists were taken aback when a shark egg case dropped by an adult bamboo shark, who spent nearly 4 years isolated from males, showed signs of healthy development. Their results mark the longest documented case of sperm storage in any species of shark, and highlight a bright bit of news for the future of wild sharks threatened by overfishing and habitat loss.

Unusual light signal yields clues about elusive black hole merger

Science Daily - Thu, 08/01/2015 - 2:44pm
Scientists have found what appear to be two supermassive black holes in the final stages of a merger, a rare event never seen before. The discovery could help shed light on a long-standing conundrum in astrophysics called the "final parsec problem," which refers to the failure of theoretical models to predict what the final stages of a black hole merger look like or even how long the process might take.

Heinlein's 'All You Zombies' Now a Sci-Fi Movie Head Trip

Slashdot - Thu, 08/01/2015 - 2:40pm
HughPickens.com writes: Sara Stewart reports at the NY Post that the new sci-fi movie Predestination, opening January 9, is "loopier than Spielberg's [Minority Report]; its plot twists and turns 'like a snake eating its tail,' one character remarks, until you're not sure whether its developments are even plausible in a fictional universe." It's based on Robert A. Heinlein's science fiction classic All You Zombies, first published in 1959. The story involves a number of paradoxes caused by time travel, further developing themes explored by Heinlein in a previous work, By His Bootstraps, published some 18 years earlier. Predestination's plot concerns the intersection of a time-traveling assassin and an androgynous young writer

Preventing transformer explosions

Science Daily - Thu, 08/01/2015 - 2:20pm
Technology used in the crumple zones of cars can avert serious explosions in transformers, believe researchers. Large oil filled transformers are found in all power and switching stations, as well as in many large buildings. If an internal short-circuit occurs, an electrical arc, gas formation and pressure increase will be the result.
