The paradox is that we must judge the state not according to what we would do if we controlled it, but in the light of what it could do if our enemies controlled it. It’s existence, like nuclear weapons become a factor in itself. The playwright Robert Bolt understood what the Bolivarians did not: the state can be dangerous unless it can be made predictable. As one of Bolt’s plays puts it: “the law is not a ‘light’ for you or any man to see by; the law is not an instrument of any kind. …The law is a causeway upon which, so long as he keeps to it, a citizen may walk safely.”
A good artcle on batteries in Power Electronics, triggered by the Samsung Galaxy Note 7 Debacle, and the not to distant past mess with the ‘hover board’ craze. The article links to a pretty detailed recent study of coming high power density battery technologies.
The eMagazine http://www.powerelectronicsnews.com/ is a good source on power electronics across the power and technology range. A good way to keep up on a rapidly changing field.
The article talks about a variety of battery chemistries including sodium as shown in the following graphic.
However the main reason I show this graphic is the incredible density of information that the graphic data presenter/artist at Macmillan Publishers was able to insert into a relatively small and simple chart. For me as a technologist this gives me the ability to data dive and compare and contrast very quickly when considering alternatives. My experience in buying reports or data repositiories of one sort or another is that the quality of this sort of chart is key to the value of the document
Going to see if HW helps. I’ve always loved Thinkpad keyboards and small laptops, let’s see if this is progress towards nerdvana.
Good article at the Singularity Hub it’s obvious to me that the hamburger flippers’ days are numbered, so how will society adjust? Luddism only goes so far, the general populace will see the bitching, moaning and breaking things as what it is, the last gasps of the un imaginative and paleoProgressives unable to see it ain’t 1959 any longer.

On Tuesday, curiosity and expectations were ratcheted up significantly with the unveiling of NASA’s Johnson Space Center entry, a humanoid robot called Valkyrie (R5). This is a 6-foot-two-inch, battery operated robot weighing 286 pounds with 44 degree of freedom. (The Valkyrie has seven degree of freedom arms, for example, with actuated wrists and six degree of freedom hands. Each hand has three fingers and a thumb.)
When walking on muddy or bumpy roads, the two arms of DRC-HUBO become extra legs, enabling stable and agile movements.
On Monday, July 8, 2013, the seven teams that progressed from DARPA’s Virtual Robotics Challenge (VRC) arrived at the headquarters of Boston Dynamics in Waltham, Mass. to meet and learn about their new teammate, the ATLAS robot. Like coaches starting with a novice player, the teams now have until late December 2013 to teach ATLAS the moves it will need to succeed in the DARPA Robotics Challenge (DRC) Trials where each robot will have to perform a series of tasks similar to what might be required in a disaster response scenario.
Kept in the Dark Secrecy is a two-edged sword

AW&ST is doing the reveal on the air forces reason for trying to can GlobalHawk :Among other things:
Secrecy distorts debate. A House Armed Services Committee hearing
in April bordered on farce. The Air Force has been trying for a couple of years to reduce its fleet of Global Hawk unmanned air systems, because the big UAS is no more survivable than the much less costly General Atomics MQ-9 Reaper, while protecting a classified stealth UAS under development by Northrop Grumman. In that hearing, Lt. Gen. Charles Davis, the USAF’s senior acquisition officer, practically had to play charades to convince Rep. John Gara- mendi (D-Calif.), whose constituents fix Global Hawks for a living, that the Air Force did have a reason for disfavoring his pet bird, without exactly saying what it was, because it was secret.
So you and I paid for hundreds of millions dollars worth of obsolete capability. And heck, the workers can’t support PACs to lobby for their livelihood…
The Shipping Container
A Cyber Monday paean to the unsung hero of consumer capitalism: Craig Martin @ The Atlantic
Busan New Port, South Korea (Reuters).
At the world’s ports, rows of stacks of shipping containers in an array of colors create a rich metallic vibrancy. On construction sites they are used as storage boxes. They can be seen lying prone and rusting in abandoned plots. They perch on the back of trucks speeding down the motorway. On flatbed cars they trundle through railway stations, box upon box upon box.
McLean (U.S. truck operator Malcom McLean’ the container systems inventor) understood that a transition to container shipping would require the complete redesign of the entire freight transport infrastructure: rail cars, ships, trucks, cranes, dockyards, everything. As a starting point, he commissioned the container engineer Keith Tantlinger to design a new aluminum container, and to reconfigure a decommissioned tanker vessel, the Ideal-X, to accommodate the new containers. Tantinger also developed a further piece of equipment, the container spreader bar, which enabled the container to be lifted without the need for stevedores to attach roping. As the economist and historian Marc Levinson has noted, the design of the spreader bar meant that “once the box had been lifted and moved, another flip of the switch would disengage the hooks, without a worker on the ground touching the container.” Container freight was all about increasing the speed of movement and reducing the cost of labor. Although the Ideal-X sailed for the first time as a container vessel in April 1956, it was not until 1970 that the International Organization for Standardization (ISO) agreed on the standardized sizes and certain fixings for containers (or ISO Containers as they are formally named).
