Overheard – Lean production and specialization are at odds

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
earll_murman.jpg The hierarchical and rigid structure [of the traditional organizational structure] results in extreme specialization of job functions and a large number of job classifications; it is incompatible with the team approach of lean production, in which workers perform many tasks and have few job classifications.

Overheard – Virtual port technology provides user with reliable wired-like experience

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
radio-wave.jpg With the introduction of virtual port technology, the common pooled resources of virtual cells can be partitioned into multiple virtual WLANs, with a unique WLAN for each user device; the dedicated virtual WLAN moves with the user as long as his device is connected to the wireless network.

Mirko Zorz, Meru Networks brings virtualization to wireless LANs

As with wired switches, the network has full control over the resources and services allocated to a given device. Because the device is “sandboxed” in its own virtual WLAN, the user has a highly reliable wired-like experience, with full access to appropriate resources yet protected from disruptions by other users’ network demands. When devices are partitioned into their own dedicated virtual WLANs, the network can control client behavior in ways that proprietary client driver extensions and AP radio management technologies cannot – without adding any client software. As with virtual cell technology, virtual port technology is fully based on IEEE 802.11 standards.

Overheard – IBM takes a page from Apple when building Blue Business Platform

Overheard – Who wants to be Obama’s National CTO?

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
elizabeth_corcoran.jpg Silicon Valley is chattering about who will get tapped to be the nation’s first “chief technology officer” in the Obama administration. There’s no doubt the job will be a tough one but could offer one surprising perk: a quiet way to cash out of a stock portfolio and invest in, say, Treasury bonds, while significantly deferring any capital gains taxes.

Elizabeth Corcoran, Obama’s CTO: It’s Not About The Money

But the job that the Obama team has in mind seems to be less about setting a lofty vision statement for the government and more about orchestrating tactics to get different agencies to cooperate, share best practices and live up to the goal of creating a “more transparent” government.

Overheard – Replacing Infiniband with 10GE

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
dan_tuchler.jpg Sure, it’s proven, and a lot of people use it. But like many proprietary technologies, it also has some unappealing characteristics. It demands specialized expertise. It’s not always as fast as advertised. It’s not completely reliable. It certainly doesn’t work and play well with others. Yes, we are talking about InfiniBand.

Dan Tuchler, Incoming: 10 Gigabit Ethernet for HPC

When it comes to reducing capital and operating expenses, one infrastructure is simply better than two — or more — and the HPC environment is no exception. High-performance computing clusters that use an InfiniBand interconnect also use Ethernet. Ethernet is necessary for user and storage connectivity, and for the management network that orchestrates the cluster. Replacing the InfiniBand interconnect with 10GE to create a single, all-inclusive infrastructure will cut hardware and power costs, and simplify manageability. And, that infrastructure combines high performance with low power needs and a sufficiently low latency for many HPC applications, making it an excellent fit for technical and budget requirements.

Overheard – Data mining collective intelligence

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
thomas_malone.jpg For most of human history, people have lived in small tribes where everything they did was known by everyone they knew. In some sense we’re becoming a global village. Privacy may turn out to have become an anomaly.

Dr. Thomas W. Malone, as quoted in You’re Leaving a Digital Trail. What About Privacy?

This New York Times article is about a bunch of kids at MIT who are trading their “privacy” for a free smartphone. The article ends with this quote by Dr. Thomas Malone, the director of the M.I.T. Center for Collective Intelligence. He’s got a good point. I remember stories my grandmother told about kids listening in on her parent’s “party line” or how the small-town operator in our upstate New York town was such a gossip that if you had something confidential to share, you would NEVER use the telephone.

Overheard – Frank Gillett’s cloud computing reality check

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Forrester’s Frank Gillett talks with Beet.tv about “cloudwashing.”  He does a nice job breaking down where the future might lie for cloud computing and unlike a lot of other pundits, Frank seems to have his feet on the ground (and not in the clouds).  Don’t miss this one.

Thanks go to Dennis Shiao for recommending this video clip. My takeaway?  I need to keep an eye on three things: software as a service (SaaS), platform as a service (PaaS) and virtual infrastructure as a service (usually shortened to just IaaS).

Overheard – Disruption Tolerant Networking Protocol

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Alan Boyle, Interplanetary Internet Passes Test

Today, NASA’s information superhighway to outer space flows through one major gateway – the Deep Space Network – to a host of space probes, scattered all the way out from Earth orbit to the edge of the solar system. As those probes proliferate, the Deep Space Network has to keep up with an increasingly complex communications schedule.

The new protocol developed by NASA to deal with complex communication scheduling is called Disruption-Tolerant Networking (DTN). It’s sort of works like TCP/IP, but it doesn’t assume there will be a continuous end-to-end connection. If a destination path can’t be found, the data packets aren’t discarded. Instead, each network node keeps the information until it can communicate safely with another node. It’s called a store-and-forward system.

Overheard: Future of clouds remain hazy without standards

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
benjamin_ellis.jpg It is clear that without standards of one kind or another (de-facto or from a recognised body), there won’t be a market, and without a market, the cloud is unlikely to thrive. The competition isn’t as much between cloud providers, as it is between cloud providers and internal IT organizations. Cloud providers need to keep that firmly in mind.

Benjamin Ellis, CloudCamp London 2: On Standards. Special Guest Post

A standard image format might provide a base level of standardization, but there is a risk that the industry then gets caught up in a ‘lowest common denominator’ model that throttles much of the unique innovation that the scale and speed of cloud computing allows. There was a consensus for a pragmatic approach: a layering of APIs, standardizing a layer at a time.

(My apologies to Benjamin Ellis! I had originally credited this quote to James Govenor.)
