Intel Thunderbolt: a closer look (updated with video)
So what's this Thunderbolt stuff, and why is it in your new MacBook Pro? Intel just broke it down for us, and now we'll do the same for you. Simply put, Thunderbolt's a familiar-looking port, a brand-new chip, and a cord, which allows devices to pipe two data streams simultaneously -- in both directions -- over a single cable at up to 10 gigabits per second to start, primarily using PCI Express x4 for data and DisplayPort for video. The Thunderbolt controller chip -- required for the system, but Intel says it's hardware-agnostic and doesn't require an Intel processor or chipset to use -- acts as a miniature router of sorts that rapidly switches between the two bidirectional channels of data. Sounds great, but why would you want to buy into yet another copper cord? Intel defends that Thunderbolt will be backwards and forwards-compatible depending on the cable used. Representatives explained that the basic system can work with any other PCI Express 2.0-compatible I/O system with, say, a FireWire or eSATA adapter doing the dirty work --Intel wouldn't specifically comment on USB 3.0 -- and that the port you'll find in new MacBook Pros and storage devices can actually take an optical cable when those are cost-effective enough to roll out, because Intel will eventually bake the optical transceivers into the cables themselves. In the meanwhile, you can get up to three meters of range out of a basic cable, plus a fairly generous 10 watts of power over the bus, and since Thunderbolt devices are designed to be daisy-chained, you may be able to get another three meters for each device you add on that sports a pair of the ports. Though Intel wasn't talking about likely prices for the chips or cables in even the most general terms, Promise and LaCie had prototype devices on hand headed to the market soon -- get a peek at them and a closer look at the cable in our gallery below, and we'll have video up in a little while too. Update: Looks like LaCie's product now has a name and vague release date: it's the LaCie Little Big Disk, coming this summer, with a pair of solid state drives inside. Update 2: Video after the break -- get a load of Thunderbolt streaming four 1080p clips from a MacBook Pro and attached Promise NAS simultaneously! %Gallery-117530%
Researchers aim to replace copper with aluminum as a conductor in auto power systems
As every lonely cat lady with a police scanner knows, the price of copper is as high as it's ever been -- and there is no reason this trend won't continue. Of course, this affects more than those creeps that sneak into basements to steal the plumbing: the aforementioned ductile metal is currently the best conductor for on-board power systems in automobiles. But with any luck this might soon change. In order to replace copper with aluminum in power supply systems, several challenges need to be addressed, including the fact that aluminum creeps as temperatures increase, and the corrosive effect of bringing the two materials together. Among the efforts of Technische Universitat Munchen (TUM) and BMW to bring aluminum into EVs, the LEIKO power plug uses a sheet metal cage and a pressure spring to allow copper and aluminum elements to remain in contact. If all goes according to plan, TUM's Professor Udo Lindemann (not to be confused with Udo Dirkschneider, the diminutive frontman of German heavy metal bands Accept and U.D.O.) predicts that "the high-voltage on-board systems of most electric vehicles to be based on aluminum by 2020." Check out an awesome picture of Dirkschneider after the break.
Intel: Light Peak is ready for implementation, but it's built on copper
It's the classic good news / bad news dichotomy: Intel's highly anticipated Light Peak interconnect is totally ready for implementation into consumer devices, but its present iteration is based on communications over boring old copper wire instead of fiber optics. The company's David Perlmutter says transmissions over copper turned out "surprisingly better" than expected and that it'll prove plentiful for the majority of user needs today. Yeah, maybe, but we don't suffer bouts of gadget lust based on our needs, it's our wants that keep us up late at night dreaming of dual-core smartphones and tablet-optimized Androids. Then again, it's not like the 10Gbps optical option has been dismissed out of hand, it's just that we'll probably have to keep on waiting for it for a little (or a big) while longer.
Nokia Siemens Networks sees 825Mbps over traditional copper, Phantom DSL claims 'the future'
Look, it's not easy nor cheap to lay an entirely new network infrastructure -- just ask Verizon. Regardless of how badly we all want a fiber optic cable ran directly into our closet, it's probably in our best interest if companies like Nokia Siemens Networks continue to improve existing services. Since we're on the topic, it's probably prudent to point out a new discovery surrounding existing copper wires -- one that involves data transmissions at up to 825Mbps. As the story goes, NSN is testing new technology (let's call it Phantom DSL) that could dramatically increase capacity of conventional copper wires, with the aforesaid data point coming on a trial transfer across 400 meters of wire; when stretched to 500 meters, it still held steady at 750Mbps. We're told that Phantom DSL promises a bandwidth increase of 50 to 75 percent over existing bonded copper lines, but mum's the word on when ISPs will actually have access. Yesterday, please?
Huawei breaks DSL speed barrier with 700Mbps prototype
DSL cables might not really be the sexiest thing in networking anymore, but what they are is ubiquitous, so let's not begrudge Huawei its feat here. The Chinese telecoms facilitator has shown off a new prototype that can pump 700Mbps of data across a 400-meter expanse. This is done by bundling four twisted pairs of copper wire together and sprinkling in some fairy dust to make them communicate at 175Mbps each. The clever bit here is in how crosstalk and interference are minimized, and Huawei claims a 75 percent improvement in bandwidth as a result. An immediate opportunity for these new cables will be, ironically, with fiber rollouts, as they could serve as the last connection between fiber hubs and your home. Then again, with Google and Chattanooga already looking at 1Gbps lanes, maybe the day of the copper wire has already passed?
Sony replacing handset wiring with a single copper cable
Sure, it's just boring ol' component news but you can guarantee that this advance will affect the appearance of Sony (and Sony Ericsson) products some time soon. Sony just announced the development of a "single wire interface technology" that replaces the 22 or so cables (used for power, control signals, audio, video, etc) typically found inside mobile devices (tucked away in the hinge or rotating parts) with a single copper wire cable capable of transmitting data at 940Mbps. That should translate into greater reliability while giving Sony's product teams more flexibility with their designs. Sony plans to "swiftly" implement the technology by licensing the IP to ROHM to help jointly develop the required silicon. More with less, as they say.
Verizon CEO doesn't care about landlines anymore, feels 'liberated' by new outlook
Verizon Communications CEO Ivan Seidenberg isn't too upbeat on the future of landlines, telling the audience at a Goldman Sachs investor conference today that the company is just not interested in telephones connected with wires. The chief exec of one of the nation's biggest telecommunications firms continued with his gospel, saying his "thinking has matured" and that trying to predict when the dwindling landline business will plateau is akin to "the dog chasing the bus." He says the new way of thinking is "liberating," but of course, endeavors like the Hub technically don't count as landlines to the company since it'sVoIP, and the coupled with its continued success as the largest cellular provider in terms of subscriber base, yeah, we're sure it's not too tough a pill to swallow. So how abut ramping up FiOS installations just a wee bit faster, eh Ivan?
Blizzard starts selling gold (coins)
I don't have a lot of detail on this, but the news from Comic-Con is that Blizzard is finally starting to sell gold! Collectible WoW-inspired gold, silver, and copper coins, that is. What did you think I was talking about? They'll come in both Horde and Alliance versions, and are being made by DC Unlimited. DC also handles the WoW comic, so that's unsurprising. If we hear anything more on pricing and/or availability, we'll be sure to let you know.
China's super buoyant, super small copper boats
Researchers in China, inspired by Mother Nature, have developed postage stamp-sized copper mesh boats, "some of the most buoyant" yet devised. Taking a page from both the shark and the lotus, the team applied a rough and uneven coating to the surface of the mesh, which reduces the vessel's contact with water. Next, a hydrophobic was applied, which keeps water from penetrating the porous material, "even when they are carrying a load," according to Dr Qinmin Pan, a chemist from Harbin Institute of Technology. "We believe these boats are some of the strongest ever built - in terms of the mass they can carry." Possible uses for the superhydrophobic material include microfluidic devices (where minuscule amounts of a liquid are used to carry information on a chip) and miniature aquatic robots. As you know, ensuring replicant diversity is an important part of their plan.
All the World's a Stage: So you want to be a Miner
This installment of All the World's a Stage is the twenty-eighth in a series of roleplaying guides in which we find out all the background information you need to roleplay a particular race or class (or profession!) well, without embarrassing yourself. Mining is one of the strangest professions in the World of Warcraft. This may seem counterintuitive in the face of such odd professions as alchemy, and more particularly, engineering. But when you think of it, mining is equally strange in its own way.Mining in the World of Earthiness is by and large a capitalist venture, where the people getting rich off of the various precious metals in the world are never ever the same people who actually go out and dig the stuff out of the ground. No, the rich people find other people do to the actual digging for them, and then compel those diggers to hand over the fruits of their hard work for a mere fraction of the work's actual value. Furthermore, precious metals here on Earth are not simply lying about at the surface for anyone with a pickaxe to come along and collect -- otherwise those metals wouldn't be precious anymore. Mining on Azeroth is more like collecting interesting seashells than it is anything similar to what humans do on Earth. Below, we will find a few ideas about why in the world only the very greatest adventurers with the best training can go around picking up shiny ore nodes sticking up out of the ground, as well as what it might mean to your character to do so.
Loken the most dangerous mob in the game
The Top Lists on the official World of Warcraft website are endlessly interesting and fascinating. The last time we looked at them was well before Wrath launched, so we decided to take a look again now that we've been in Northrend for awhile.The first list I looked at was, of course, the Most Dangerous Creatures. What's more fun than seeing what's destroying your fellow players? Nothing. Nothing at all. It looks like Loken of Halls of Lightning is topping the charts right now, followed by Sapphiron of Naxxramas. I can see that. Loken can be pretty deadly, especially on Heroic. Most players will probably wipe to him at least once their first time seeing him, assuming they don't know the strategy ahead of time. Sapphiron is just plain painful.
ASUS at it again, calling out Gigabyte's excessive copper usage
Oh ASUS, you bring us such joy. When this company isn't busy diluting its Eee brand, it loves to pick fights with noted rivals, and this latest spat with Gigabyte (who isn't at all innocent in this war) is wonderfully trivial. Apparently ASRock, ASUS's budget motherboard wing, has taken it upon itself to inform hardware review websites like HEXUS of Gigabyte's wasteful implementation of copper. The email ponders: "While the demand for copper keeps increasing and with that the price of this natural resource, why would manufacturers choose to use more copper without any valid reason?" And it gets better: "I [unidentified] am not talking about unnecessary heatpipes that most people do not need, but about Gigabyte's '2 oz Copper PCB'. Gigabyte is adding more copper to the PCB to reduce the heat that is produced by their motherboard, and to spread it across the motherboard so that the heat will dissipate more quickly." Naturally ASRock's own P45 motherboard falls into none such pitfalls, offering better cooling with less copper, and they even provided a handy chart up above in case you don't believe them, you idiot. Say no to waste![Thanks, Jordan]
Insider Trader: To prospect, smelt, or let alone?
Recently, a reader wrote in with a question that everyone ponders from time to time. When trying to make money from a profession, it can be difficult to determine what to sell, what to convert, and what to avoid doing all together. Here's what she asked:Hello, When making gold from Mining, is it better to Prospect the Ore? Or is it better to just sell the Ores and Bars?Thank you!Regards, Kristy. Taking a break from the faction recipe series to shake things up a bit, let's take a look at how this breaks down.
Nokia N95 8GB, now in "copper"?
Nokia has historically had a tendency to release new colors of existing phones without much of an official announcement, and we could be dealing with that sitch again here. Retailer Plemix is now offering the N95 8GB in the black that we're all accustomed to along with a new shade -- copper -- that runs a few dollars more than the original. Hey, you've gotta pay to play, right? We're hearing that the copper version maintains the black front end, which would be inline with the original N95's tendency to sport silver up front regardless of what's going on around back. If anyone gets one of these copper suckers in their hands, do let us know, won't you?[Via IntoMobile and Cell Addict Blog]
Surprise: cable companies edging closer to bandwidth exigency
We know, it was a year ago yesterday that we had this very same conversation, but apparently, cable companies aren't heeding the advice of analysts. According to yet another study, this time by ABI Research, "cable providers will soon be faced with a serious bandwidth crunch" as more and more individuals look to online gaming, video-on-demand, and IPTV for enjoying their precious moments of leisure. Compounding the problem is the growing demand for more HD channels in the lineup, and considering that the satellite operators are already raising the bar, cable carriers can only play dumb for so much longer. Stan Schatt, VP and research director for ABI Research, was quoted as saying that "digital switching is key" to releasing some of the strain on current infrastructures, and while we aren't ones to believe that the influx of online TV delivery will debilitate the internet (or cable providers), something seemingly has to give -- and soon.[Via Slashdot]
Vietnamese fishermen mistakenly swipe miles of fiber-optic wire
While this mishap may not look as if it would cost Vietnam nearly as much as the Alaskan vaporization, losing 27-miles of critical fiber-optic cabling connecting the underdeveloped nation to Thailand and Hong Kong is fairly serious (and pricey). As it turns out, hordes of Vietnamese fishermen were given permission to salvage war-era undersea copper lines to fetch whatever price they could on local markets, but things got out of hand when vital telecommunication pipelines began getting swiped instead of antiquated cabling. The country has since disallowed the removal of any underwater wire until things pan out, but it looks like Vietnam will be relying on a single cable to the outside world until it can pony up the $5.8 million in replacement costs.
Ambit Broadband's Channel Bonding cable modem does 144Mbps / 30Mbps
Questions surrounding cable's ability to keep up with the big boys have been circulating for what feels like ages, but an intriguing new product from the labs of Ambit Broadband has some fairly substantial numbers to go along with it. The firm's Channel Bonding cable model will be available exclusively to subscribers of Hanaro, and by partnering with Netwave, the device will enable "triple play service" consisting of VoIP, IPTV, and high-speed internet. More interesting, however, is the reported maximum speeds that this thing can handle, as it boasts the "capability to bond three downstream channels to enable a maximum 144Mbps downstream and up to 30Mbps upstream." The modem also supports the usual interfaces such as gigabit Ethernet and USB 2.0, but it supposedly comes pre-ready for DOCSIS 3.0 and IPv6 -- you know, the protocols used to shatter the Internet2 transmission record. While it may all sound a bit sensational at the moment, the truth shall be unveiled when Ambit / Netwave delivers 150,000 of said modems to Hanaro "during Q2" of this year.
Copper Treo 680 is back!
After our tear-filled eulogy of the Copper 680, we're pleased to report that rumors of the phone's death were greatly exaggerated -- specifically by Palm, who's "no longer available" warning kind was giving off those discontinued vibes. Those old messages have been removed from Palm's site, which is now listing all colored versions of the Treo 680 as shipping within 1-2 business days. So if you were holding off on a purchase, we're guessing you know what to do -- you internet savvy shopper, you. Still, and we're sorry to sound like a broken record here, but now that you've got those supply issues sorted out, how 'bout you start working on shaving a few millimeters off these things, huh Palm?
