The 787 Dreamliner made its first commercial flight back in October 2011, and at the time Boeing had 821 planes on order. The Dreamliner can carry 250 people and was designed using the latest and greatest CAD and simulation software. The "plastic jet" is manufactured with carbon fiber and other composite materials to reduce the weight of the craft.Recently the 787 electrical power backup systems, based on large lithium ion batteries, have caught fire in two cases and that has forced the grounding of the fifty planes that Boeing has shipped to customers so far. The cause of the battery overheating and fires is being investigated, and no conclusions have been drawn as yet. Perhaps a call to Round Rock is in order.This may seem like a bit of déjà vu to Dell, the man, who has been burned by lithium ion batteries in the past. Well, not literally, but certainly financially. Back in December 2005, Dell issued a recall on lithium ion batteries used in a number of its laptops, and shortly thereafter there was a wave of exploding laptop battery stories, including one UK homeowner who claimed his Dell laptop set his living room on fire. In August 2006, as this wonderful picture in The Telegraph captures , Dell had to issue the largest recall in computer industry history because the batteries were still going pop-pop.

No one was injured by the Dell laptop battery fires, and thus far, no one has been injured on the Dreamliners, either. That's the good news.Maybe Dell should take the train. Unless the train has lithium ion batteries. A Chevy Volt is absolutely out of the question for Dell. Perhaps he should just ride a bike. Microsoft may be playing its cards too closely to his chest for its Windows 8 Surface Pro slate: there's no word on a UK launch date nor any effort to bring the business-to-business distribution channel onside.As revealed yesterday, the Intel-powered Pro slab - billed as an office PC replacement - will be rolled out in North America via Microsoft's own retail stores, the microsoft.com website and a handful of retailers in just over a fortnight - a little later than planned.But the UK launch date, and any master plan to involve distribution partners that sell to professionals, remain secrets that are closely guarded by the marketing ninjas in Redmond."We haven't announced any B2B channel plans yet and have only said US and Canada so far," said a Microsoft PR handler.

Roll back a couple of months and recall that Microsoft punted ARM-powered Surface RT gear directly to customers. Analysts claimed sales were sluggish and retailers were eventually brought into the fold.The touchscreen-laptop-tablet Surface Pro is pitched as a PC replacement - reflected by its not insignificant $899 entry-level price point - and some channel insiders expressed incredulity that they haven't been given more info by Microsoft."Microsoft is keeping its card very close to its chest," said one large partner. "Pro is not a cheap bit of kit and it's got to be a PC replacement. That is where it'll be marketed, therefore it amazes me that the B2B channel is not being involved."Microsoft tends to rely on its army of business-to-business channel warriors to supply its commercial customers worldwide. Despite this, disties report they are far from buckling under the weight of demand from resellers; one claimed it was receiving only "gentle interest".

"Am I selling lots of Pro tablets from other vendors? No. Availability is OK but demand isn't massive. They're not flying out of the door," he said.Maybe SeaMicro, the upstart maker of low-power microservers that dragged Intel kicking and screaming into the market, should have bought AMD instead of the other way around. Or maybe after the AMD transformation is all done some years hence, it will look like that is what happened anyway so the difference will be moot.There's no question that AMD is not having an easy time right now, as its latest financial results show. After having to renegotiate its wafer supply agreement with fab partner GlobalFoundries, the company posted a $473m net loss compared to the year-ago period's gain of $71m as revenues dropped 31.4 per cent to $1.16bn. If you ignore that renegotiation, AMD still lost $55m, and you can't really ignore it anyway.The problems AMD faces are complex, and so are its answers to them.A resurgent Intel in the data center has hurt AMD's Opterons since early 2009, and many server makers either abandoned AMD entirely or only give it minimal support in their servers. HP, Dell, and Super Micro are probably AMD's biggest friends, and the loss of Cray as a volume customer, which is shifting to Xeon E5 chips for its latest XC30 supers, will hurt AMD for years to come.

AMD has excellent GPUs, but seems to have lost its way competing against Nvidia in the fast-growing market for GPU accelerators for supercomputer workloads. The company's Fusion APU chips could turn out to be useful on this front, if AMD can marshal the software tools and partners to make it so. Thus far, Nvidia has stolen all the headlines and most of the business with its CUDA programming environment and Tesla GPU coprocessors.The PC biz on which both Intel and AMD are dependent is hurting, and neither can get into tablets, smartphones, or embedded devices fast enough to fill in the gaps. AMD is going to deliver ARM-based Opteron processors for servers next year, but that didn't help 2012's financials and it won't help 2013's numbers, either.So it was not much of a surprise that AMD's Computing Solutions division saw revenues fall by 37 per cent to $829m in the fourth quarter ended in December and by 20 per cent for the full year to just a hair over $4bn. And thanks to restructurings and the rejigged wafer contract with GlobalFoundries, Computing Solutions had a $231m operating loss for the year.This is a tough business, and it is going to get a lot tougher as ARM processors continue to ride up the smartphone and tablet waves and make their way into PCs and servers.

AMD does not break out specific revenue and shipment figures for its server processors and chipsets, but on a conference call with Wall Street analysts on Tuesday after the market closed, newly appointed CFO Devinder Kumar, said that the server business was up sequentially, helped no doubt by the rollout of the Opteron 6300 processors in early November and the Opteron 3300 and 4300s in early December.Server chipset revenues and server CPU shipments were down, as expected, but Opteron revenues overall were up sequentially thanks to their adoption in dense hyperscale servers. And, while Kumar did not say this, Cray's many big deals for Opteron-based XE6, XK6, and XK7 supers, with many hundreds of thousands of cores shipped in the second half of the year, certainly helped a little, too.Server and fabric interconnect maker SeaMicro, which AMD purchased for $334m back on Leap Day (February 29) in 2012, was privately held before AMD bought it and AMD doesn't talk about its business except very generally to this day.

CEO Rory Reed say that AMD "recorded significant revenue growth" for the SeaMicro servers, which is great, but you have to remember that AMD only just started shipping an Opteron-based SM15000 machine late last year using a custom Opteron 4300 part.SeaMicro did pretty well with its initial Atom-based machines, but a year ago when it dropped a Xeon chip in the boxes, the business really took off. So while having SeaMicro on the rise is good, it is helping sell Intel chips up until now and, perhaps more importantly, AMD is competing with server maker customers who might otherwise build machines based on Opterons to attack these hyperscale workloads.Eventually, AMD will be able to sell SeaMicro's "Freedom" interconnect and both x86 and ARM Opteron parts to server makers as raw components. But that day is not here yet, and the question that AMD has not answered to anyone's satisfaction is how it will transition SeaMicro from a server maker to a set of components for server makers."We will combine our extensive 64-bit design experience, X86 processor IP, and ARM processor cores with our SeaMicro Freedom fabric to continue to drive leadership as the industry transitions to dense servers," Read said on the call, saying that Q4 was the best quarter ever for dense servers.

"We believe we already have significantly more dense server customer installations than any other competitor, thus making our SeaMicro technology the most-tried dense server solution available in the industry."That's Read talking like a server vendor, not like a parts supplier. And that's fine, so long as AMD has concluded that it wants to fight the war in the data center instead of selling bullets. And honestly, given how badly it was treated by Sun/Oracle, Fujitsu, Acer, and IBM, which dropped Opterons like hot potatoes as soon as there was a bug in Barcelona Opterons as an excuse to not have to incur server engineering costs, you can't blame AMD if it wants to control its own systems and control its own fate.SeaMicro would have had to come to the same conclusion if it were an independent and fast-growing company, too. It would have had to license ARM processors and maybe even Opteron processors and design its own processors to mesh with its fabric. The reason is simple: Networking and computing will not be separate in future systems.
