Submission + - Windmill Blade Molds 3D Printed by National Labs (

MountainLogic writes: Last year ORNL produced a 3D printed Shelby. This year, the National Labs are using the mother of all 3D printers to make windmill molds cheaper and faster to produce in the US. The size of the current 150 foot utility scale blades are being extended with these techniques. US DOE is providing a leading role to advance US manufacturing technology and competitiveness. Welcome back rust belt, we missed you.

Comment Re:Militia ? (Score 1) 336

The militias defined in the constitution are controlled by the federal government. There is no right to self organize an army or rebel anywhere in the constitution. In article 1 section 8 th power of congress include:
"To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;
To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;"

and in Article 2 section 2 the powers of the President include:
"The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment.

Read the the document folks before professing what you've been miss told what it says. The militias were added in the constitution to help repel invasions and to put down insurrections. Somehow, I just don't see these clowns taking orders from their Governor or our President.

Koreantoast, Militia was the first word so it was properly capitalized, but these are really lower case militia. Perhaps, even better labeled as wannabe war lords.
Far too many of us have forgotten the intent and history of the term militia in the constitution. The intent of the 2nd amendment and Militia was driven by peoples fear of a weak federal government that could not protect them from insurrections because of the scare from Shay's rebellion. In the case of Shay's the post revolution federal continental government refused to open the federal armories so that the sate Militias could respond to an upstate New England insurrection. The armories were filled with weapons from the revolution that were paid for by the "national" government, but often ended up in the hands of the local units at the close of hostilities so not having access to what the local's saw as their arms was a sore point. At any rate, the anemic response of the national government tightened many such as Hamilton and Madison and was one of the motivators of the constitutional convention. You can see the car intent of the writers of the second amendment and militia clause in the Federalist Papers, especially #29. Hamilton does go on a fair bit on the importance of federal control of the Militia, that it be well regulated and by well regulated he means well trained and under tight federal control to prevent war between the states. Chaos from a weak central government was a big concern in the nascent US - the thought of federal tyranny would have seemed laughable at the time. There has been massive revisionist history of the early republic to fit modern agendas.
If you want to see the first application of the Militia and 2nd amendment read about the Whiskey Rebellion. When some local hot heads ruffed up a federal official and take over his office, George Washington federalized 13,000 members of the state militia and using the leverage of the 2nd amendment forced the states to open their armories to equip the force. Washington lead the force, the only President to lead an army into battle, and rounded up the remaining 20 hot heads where were too dumb to go home when he arrived. By the way, even though Washington praised the militia publicly, he complained bitterly in private letters to members of congress that they were useless and undisciplined rabble.
Interestingly for recent event, Article IV, Section 4 speaks to the fact that the federal government had no choice, but to act as: "The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened), against domestic Violence." And the Oregon Governor did call for federal action.
So, take home lesson:
US Militia == federally run arm of internal repression,
2nd amendment == state's rights to store arms for the feds under the rules the feds make.
Federal government must suppression rebellion.

Comment Re:Interview "Grilling" or "Testing" is Poppycock (Score 1) 227

On the technical side I ask basic questions. I put up a list of numbers on the whiteboard and ask them to write a function to sort them in ascending order. For example, 1, 5, -13, 2.5. I'm make it clear I don't care if they remember a particular sorting algorithm. Frank, I feel it is more meaningful if they mumble an apology about not remembering quick sort and accomplish it anyway. I just want to see if they can do a basic task than any programmer doing the type of work I do must be able to do. Some create a detailed compliable function and others write a pseudo code fragment. Either is fine, but I do ask everyone to review the code for correctness and completeness to make it check-in ready. You would think that every high school kid could do this, but you would be surprised at how many experienced programmers can't do this. This does not show if you are creative or smart. It only tells me that you have spent time writing code.
For softer skills I just chat about their past work and work environments. Honestly, the worst interviewer I had for soft skills turned out to be my best hire so it is at best it is a gamble and anybody who says otherwise is fooling themselves.

Comment Shape Memory Alloy (Score 3, Informative) 32

Shape Memory Alloy are a Nickel Titainium alloy often called muscle wire because by changing its crystal structure it gets shorter when heated or an electric current runs through it. While very different in how it works from a polymer, Shape Memory Alloy has had similar uses including heart stints, explosive bolt replacements on spacecraft, toys and heating air vent controls. Biggest down side to it is it tends to be a bit slow so it is more sloth muscle than jackrabbit muscle.

Comment Re:Privacy Complaints (Score 1) 202

Yes, body cameras are a tools for handling over reaching or abusive police activity. If the information is not handled correctly cameras will also have a chilling effect on privacy and our lives. No-knock raids aside, police are often involved in non-criminal issues. Imagine if your teenage child has a yelling incident that adolescents are prone and the neighbors hearing an unusual ruckes next door call the cops - just be be safe. Cops show up to investigate and this teen ager is yelling and crying and generally being an idiot. Sure they calm down when they likely see a cop, but that scene is caught on tape. Imagine a few years latter applying to college and this is out in the net in an easily searchable form or 20 years latter applying for a job? A middle school teacher would not think twice about the scene, but imagine inviting a cop in to report a vandalized car while caring for an alzheimer's parent and some interaction is caught out of context that then make the rounds at work. Balancing these competing needs of openness and privacy is one of the emerging civil rights challenges of our day. As we have all learned that the internet is forever, have learned to not post those selfies of ourselves being overly stupid. We can edit our own posts, but how do you unpost something in the public record? The French have the concept of being able to start fresh: oblivion. In the US we used to be able to move further west and start anew. Where is the new west with the internet?

Take a deep breath. This is only an application, not a patent. YOU still have an opportunity to participate in the process. A few hundred dollars and three little words, "I claim fire." get you a useless application for fire. Very broad claims in an initial application are not unusual and are often just the starting point for negotiating with the examiner. Hopefully the examiner will push back and get them to reality. The first claim is:
1. An electronic-device-implemented method, the method comprising: using the electronic device, generating a symmetric encryption key associated with a content item; encrypting the content item using the symmetric encryption key; encrypting the symmetric encryption key using a public encryption key for a recipient to generate an encrypted symmetric encryption key; providing the encrypted symmetric encryption keys and information specifying the recipient to a synchronization computer that communicates, via a shared network, with at least one electronic device associated with the recipient; and communicating the encrypted content item to instances of a client application executing on the at least one electronic device via secure peer-to-peer distributed sharing.

Note that every feature in a described claim must be present in your method before your method violates the patent. If you have specific prior art you should share that information by contacting the general counsel of DropBox at (415) 986-7057 and the USPTO Commissioner of Patents at 800-786-9199. Be sure to mention the application publication US20150358297 attached to applications 62008940 & 14/448972 and provide specific prior art citations (websites, brochures, publications, patents, industry standards, etc) that the patent examiner should consider. Be polite, get to the point and don't rant.

Stop whining and write a letter. Seriously, if you don't participate, don't whine. Once a patent is issued it get much harder to make changes.

Indeed antennas do have a great impact on communication, but propagation includes how the signal interacts with the environment. Atmospheric absorption is very different at varying frequencies. In particular water absorption change very quickly at these frequencies. 2.4 GHz was "given away" to the unlicensed ISM bands because it is so highly absorbed by water that it was considered as useless for long range communications. This is why microwave ovens use 2.4GHz. Also scattering/back scattering and interaction with reflectors/surfaces at a given size changes with wavelength. Generally, the lower the frequency the better the range at a given power at the cost of lower bandwidth.

There are some residential routers that have existing IoT protocols such as ZigBee and Z-Wave already build in. Not used much but they do exist. I believe that Verizon was pushing this and Lowes is sell this under the label Iris. The IoT has been the fusion power of consumer products for decades - always just around the corner with the latest shiny new thing.

ah may have modes that support lots of bandwidth, but do not think for a second that you are going to get 4k video across town over 900 MHz from an arduino running from a coin cell. The bandwidth link budget will not support it. You quickly run into the thermal noise floor of silicon. At a given sensativity of your receiver: Bandwidth ~= power / distance. You will be lucky to get 100 kBPS into your backyard. How many hours will a cordless phone last with monster batteries? This is a dream for meter reading and in your house for a very limited number of bytes per hour from a coin cell device monitoring temperature or a door alarm.
