Despite its name, the first iteration of OCuLink will be copper-based, but is being specced so that future iterations can be based on optical cabling. It's based on PCIe generation-three tech, and as Neshati put it, it's being future-proofed for future generations of PCIe as well.The cable spec allows for one, two, or four lanes, and since it doesn't carry clock signals or power over the cable, he said, the scheme will allow for low-cost cables, connectors, and ports due to the lack of the need for what he identified as complex shielding requirements.OCuLink should be available next year, Neshati said. OEMs are behind it, the connector vendors are behind it, there are some very interesting mock-ups right now that are proofing the concept.In comparison to an outside-the-box high-speed connector tech that tunnels PCIe, Thunderbolt, Neshati said that he predicts OCuLink will be a less-expensive way to connect external devices because implementers won't have to provide a controller for the cabling. Thunderbolt has a controller, he said, so you're paying extra for that chip, whereas here you're getting PCI Express for free – it's driving your cable.The PCI-SIG is preparing the imminent release the PCIe 3.1 spec, which Neshati referred to as a collector spec that incorporates a shedload of little itty-bitty chiclet changes that developers have contributed to PCIe 3.0 since it was released that improve power management and performance, and add features. The next big change in the PCIe spec, however, is expected to be released in 2015: PCIe 4.0.

PCIe 4.0 was announced in late 2011, and Neshati says that work on it is proceeding apace. PCI-SIG members are bringing in technology to drive gen-4 functionality, he said.At a maximum theoretical bit rate of 16 gigatransfers per second, don't expect to find PCIe 4.0 in your desktop or laptop. Quite simply, those mundane devices have no need for such performance – Gen-2 is enough for most applications, he said. Gen-4 will be servicing some of the very high-end server, HPC kinds of applications.PCIe 4.0, he said, will be in the datacenter competing with InfiniBand, which currently has a theoretical maximum throughput in its FDR flavor at 14Gb/sec per lane one-way, and QDR at 10Gb/sec one-way. PCIe 4.0 will have a maximum theoretical throughput of around 2GB/sec per lane one-way.PCIe 4.0 will allow for 16-lane implementation, which would thus have a total bandwidth of around 64GB/sec, both ways. By comparison, 12-lane InfiniBand FDR has a theoretical bandwidth, both ways, of 42GB/sec, and QDR, 30GB/sec.

Of course, those figures represent InfiniBand today and PCIe 4.0 in 2015; InfiniBand will almost certainly be snappier by then – in fact, testing is now underway of InfiniBand EDR (enhanced data rate), which will increase the one-way throughput to 25Gb/sec per lane. A 12-lane EDR implementation would thus have a overall throughput – both ways, again – of 75GB/sec.PCIe 4.0 will still have one advantage over InfiniBand, though: it's snuggling up with compute cores on microprocessor dies, while InfiniBand isn't – there are distinct advantages to being a legacy technology. In addition, Neshati said, the PCI-SIG's goals for the PCIe spec include low cost, high volume manufacturability.

Although Microsoft is arguably the biggest name in the PC business, it doesn't usually make computers. The company typically supplies its software to Microsoft's hardware partners such as HP, Lenovo, and Dell among others.But that all changed earlier this month when Microsoft unveiled the Surface Book — a high-end Windows laptop created by Microsoft that launches on Oct. 26. It starts at $1,499. The laptop functions as both a tablet and laptop, but not in the same way Microsoft's Surface Pro tablet does. Although Microsoft says the Surface Pro can replace your laptop, it's still primarily a tablet. The Surface Book, however, is the opposite and is built more like a laptop than a tablet — although you can still detach the screen from its keyboard to use it as a slate when needed.The reviews are in, and here's what critics are saying about Microsoft's first ever laptop.In fact, the iPad Pro is more powerful than the MacBook and even the latest MacBook Air laptop, according John Gruber of Daring Fireball. Gruber put the iPad Pro through benchmark tests, which are designed to test the speed of components in devices.An accidental breakthrough in a Stockholm laboratory 15 years ago could reap a fortune for the engineers who made it as long as they can win over some of the most demanding consumers: video gamers.

Since John Elvesjo noticed a sensor tracking his eye movements in a lab experiment, the technology he developed with Henrik Eskilsson and Marten Skogo has helped disabled people use a computer by identifying where they are looking on the screen.Camera sensors capture the reflection off the retina and cornea to gauge where the eye is, and where it is looking.The mass-market potential looks almost limitless. Advertisers could adapt billboard images depending on where you rest your gaze.A car could alert you when you're about to fall asleep. Eskilsson says eye tracking will one day be found in all laptops, smartphones, tablets and automobiles.First up is the computer gaming hardware market. As a player looks to one part of the screen, the image will pan across the landscape and open up a new field of vision.Whether it catches on in the fiercely competitive gaming industry could depend on a deal struck this year between Eskilsson's company Tobii and Ubisoft, maker of blockbuster game Assassin's Creed: Rogue.

Tracking the player's gaze, the eyes of warrior Shay Patrick Cormac look across seascapes, forts and battlefields as he hunts assassins in North America during the Seven Years War in the PC version of the game.The success of this and other tie-ins is the biggest test yet for Tobii, which is making no revenue from supplying its technology for the deal.The aim is to get enough players interested to lure other gaming companies for deals that would bring in revenue. So far it has a handful of other tie-ins and Eskilsson said eye-tracking will have to reach at least 30 to 50 games before it can be regarded as mainstream.The prize is huge: Tobii's sales ambitions suggest an overall market for gaming eye-tracking sensors that could top $5 billion a year in revenue, about six times the firm's market value.Eye-tracking makes it possible to create a more human device, said Eskilsson at Tobii's Stockholm headquarters, his laptop slipping into standby mode after noticing that he had looked away.Not only by steering with your eyes, but with hands, voice and where you are looking. All put together.Fund manager Inge Heydorn at Sentat Asset Management in Stockholm compared Tobii's gaming-focused business to a hard-to-value stock option and said its sensors must become cheaper and smaller and consume less energy if they are to be used for smartphones packing far less battery power than laptops.

They don't know if they will get power consumption down. We don't know. Nobody knows, said Heydorn, who holds no Tobii stock.Tobii dominates the market for now - its $75 million in 2014 sales is five times that of its closest rival among about 20 eye-tracking technology firms - by selling sensors as disability aids and for behavioural studies in research.Keeping that edge may prove a challenge now that big technology firms, some of them Tobii customers, are looking at whether to develop their own technology.South Korean giant Samsung's latest phone reads the position of the user's face, something Eskilsson sees as a precursor to full-blown eye tracking.Tobii's deep-pocketed backers include Swedish group Investor, with a 19 percent stake, Intel Capital and early Spotify investor Northzone, both with roughly 8 percent.Expectations for profit growth are sky-high and Tobii's share price has almost tripled since its April listing. The company is investing about 150 million Swedish crowns ($18 million) annually to expand in PC gaming.

It's going to take a couple of years for that to become a volume market. It's not 10 years away, but within a couple of years, said Eskilsson.Hans Otterling at third-biggest shareholder Northzone said Tobii was totally capable of carrying on by itself, without being swallowed by a bigger company. He said its value lay in the range of areas where eye-tracking may be applied.Imagine a surgeon, his hands free, able to steer things with his eyes. There is really just your imagination setting the limits, he said.John Sculley's tenure as Apple CEO saw the launch of the PowerBook laptop and System 7 operating system in 1991, as well as the temporary ouster of Steve Jobs. Sculley was removed from the company himself in 1993 following a series of flops, but he never really left tech.Sculley is now launching a new line of cheap Android smartphones called Obi Worldphone in Asia, Africa and the Middle East.The Obi Worldphone SF1 is a 4G / LTE phone with a 5-inch display that will sell for just $199 (£128) unlocked, and the 3G SJ1.5 will sell for $129 (£83). The devices are kept cheap with Qualcomm, Sony and Dolby parts, and Obi is focusing on design to try to differentiate itself from its competitors.

The phones came about through a partnership with San Francisco design studio Ammunition, which created the original designs for Beats headphones. Ammunition partner Robert Brunner, who had collaborated with Sculley in the past on devices like Apple's PowerBook and Newton PDA, led the effort.Obi isn't the only company gunning for the low-end Android market right now though. Chinese smartphone makers like Huawei and Xiaomi have stolen Android market share from companies like HTC with their own dirt-cheap devices. Both OnePlus devices have proved increasingly popular worldwide. Arguably there are simply too many Android brands on the market right now, and some, like LG, are making only 1.2 cents in profit per handset sold.The SF1 runs a Snapdragon 615 processor, and comes with 2GB or RAM or 16GM of storage as standard, and costs $249 (£160) for 3GB of RAM and 32GB of storage. It has a back-facing 13-megapixel camera powered by Sony's IMX214 Exmore sensor, and a front-facing 5-megapixel camera with LED flash. The cheaper SJ.1 comes with 16GB of storage and a 3,000 milliamps battery. Both phones have dual SIM slots too, and run a very slightly modified version of Android Lollipop that the company calls Lifespeed.

Since the recapture of Mexican drug lord Joaquín El Chapo Guzmán, many lurid details have emerged about his relationship with his apparent paramour, Mexican actress Kate del Castillo, revealing not only the flirtation between them, but also shedding light on just how she helped arrange a meeting between the drug lord and actor Sean Penn.But the section below, excerpted from a transcript of messages published by Mexican newspaper Milenio this week, shows just how taken he was with del Castillo. One series of text messages even revolves around Guzmán discussing with an associate the merits of several types of smartphones: the iPhone 6, Samsung Galaxy S6 Edge, and the BlackBerry Leap.After their conversation ended on September 25, 2015, Guzmán asked an associate for more information about Penn's work. When his conversation partner started to look for information about the American actor on a BlackBerry, the conversation turned to cellphones.The above dialogue seems so everyday that it's easy to forget that it was part of a longer, more furtive exchange between a powerful drug lord linked to thousands of killings and one of his associates.

In the past, Guzmán had no trouble communicating with the outside world while in jail.This time, however, the Mexican government seems to be working hard to prevent that.On Monday, Apple wowed the tech world again by showing off its new laptops and smartwatch.The best way to do an Apple event like this is to watch Twitter during it. Naturally, the #AppleLive hashtag was trending with hundreds of tweets, some of them really funny. It's like having a comedy act in one ear while Apple CEO Tim Cook talks in the other.Last month a massive, 13.8-inch tablet from the search giant showed up in GFXBench's database.The benchmarker has been a reliable source of device leaks in recent years. In 2015, the Nexus 6P and LGG4 showed up in its database weeks before they were formally unveiled.According to GFXBench, the device won't come equipped with any particularly impressive hardware, but could be distinguished by something quite radical: modularity.
