All 500 of the World's Top 500 Supercomputers Are Running Linux (zdnet.com) 288

Freshly Exhumed shares a report from ZDnet: Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list. Today, it finally happened: All 500 of the world's fastest supercomputers are running Linux. The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the November 2017 TOP500 Supercomputer list. When the first TOP500 supercomputer list was compiled in June 1993, Linux was barely more than a toy. It hadn't even adopted Tux as its mascot yet. It didn't take long for Linux to start its march on supercomputing.

From when it first appeared on the TOP500 in 1998, Linux was on its way to the top. Before Linux took the lead, Unix was supercomputing's top operating system. Since 2003, the TOP500 was on its way to Linux domination. By 2004, Linux had taken the lead for good. This happened for two reasons: First, since most of the world's top supercomputers are research machines built for specialized tasks, each machine is a standalone project with unique characteristics and optimization requirements. To save costs, no one wants to develop a custom operating system for each of these systems. With Linux, however, research teams can easily modify and optimize Linux's open-source code to their one-off designs.
The semiannual TOP500 Supercomputer List was released yesterday. It also shows that China now claims 202 systems within the TOP500, while the United States claims 143 systems.

Apple Is Back To Being the World's Top Wearable Maker (techcrunch.com) 48

Apple is once again the biggest selling producer of wearables after its third-generation Apple Watch, released in September, helped it pip China's Xiaomi to the post. TechCrunch reports: The new device, Apple's first that connects to the internet without being tethered to a smartphone, took the U.S. mobile giant to 3.9 million shipments in the recent Q3 2017, according to new data from Canalys. The firm estimates that the gen-three version accounted for just 800,000 shipments, due to supply issues, which bodes well for Apple coming into the lucrative holiday season. That figure was a big jump on 2.8 million shipments one year previous. It also gave Apple 23 percent of the market, putting it fractionally ahead of the 21 percent for Xiaomi, the Chinese firm that was briefly top of the industry for the first time in the previous quarter. Apple's wearable division has enjoyed something of a renaissance this year, grabbing the top spot in Q1 for overall wearables the first time since Q3 2015. CEO Tim Cook said in Apple's most recent earnings report that Watch sales were up by 50 percent for the third consecutive quarter thanks to a focus on health services. As for the others: Fitbit took third in Q3 2017 for 20 percent, while phone makers Huawei (six percent) and Samsung (five percent) were some way behind in rounding out the top five. In proof of considerable fragmentation within the industry, "other brands" accounted for a dominant 25 percent, according to Canalys' figures.

Investigation Finds Security Flaws In 'Connected' Toys (theguardian.com) 32

An anonymous reader quotes a report from The Guardian: A consumer group is urging major retailers to withdraw a number of "connected" or "intelligent" toys likely to be popular at Christmas, after finding security failures that it warns could put children's safety at risk. Tests carried out by Which? with the German consumer group Stiftung Warentest, and other security research experts, found flaws in Bluetooth and wifi-enabled toys that could enable a stranger to talk to a child. The investigation found that four out of seven of the tested toys could be used to communicate with the children playing with them. Security failures were discovered in the Furby Connect, i-Que Intelligent Robot, Toy-Fi Teddy and CloudPets. With each of these toys, the Bluetooth connection had not been secured, meaning the researcher did not need a password, pin or any other authentication to gain access. Little technical knowhow was needed to hack into the toys to start sharing messages with a child.

Apple Could Launch Two New Full-Screen iPhones Next Year (theverge.com) 117

Reliable Apple analyst Ming-Chi Kuo expects to see two new full-screen iPhones next year: one will have a 6.5-inch OLED display, essentially making it a Plus version of the iPhone X; and the other will have a 6.1-inch LCD display, likely making it more like a full-screen version of the current Plus-sized iPhone. Both are said to have the notch. The Verge reports: In his research note, which was reported by MacRumors, Kuo writes that Apple is hoping to "satisfy various needs of the high-end market" by expanding its full-screen product line. At the high end will be the 6.5-inch OLED iPhone; beneath that will be an updated version of the 5.8-inch OLED iPhone X; and finally, the 6.1-inch LCD iPhone will sit below both them. Kuo predicts that the 6.1-inch phone will be priced somewhere between $649 to $749 and be set apart by having a less-dense screen resolution, offering a worse picture. If Apple does introduce a 6.1-inch LCD iPhone, $749 certainly seems too cheap for it to sell at -- the iPhone 8 starts at $699 as it is, and the 8 Plus starts at $799. The 6.1-inch phone sounds like a step up from the existing Plus model, so it would make more sense to sell it for, say, $899, right between a refreshed version of the Plus and a refreshed version of the X.
