Flash Crash Analysis - May 6'th 2010 - Part 4 - Nanex
"While analyzing HFT (High Frequency Trading) quote counts, we were shocked to find cases where one exchange was sending an extremely high number of quotes for one stock in a single second: as high as 5,000 quotes in 1 second! During May 6, there were hundreds of times that a single stock had over 1,000 quotes from one exchange in a single second. Even more disturbing, there doesn't seem to be any economic justification for this. In many of the cases, the bid/offer is well outside the National Best Bid/Offer (NBBO). We decided to analyze a handful of these cases in detail and graphed the sequential bid/offers to better understand them. What we discovered was a manipulative device with destabilizing effect."

[1006.3518] Graphene: A sub-nanometer trans-electrode membrane
"Isolated, atomically thin conducting membranes of graphite, called graphene, have recently been the subject of intense research with the hope that practical applications in fields ranging from electronics to energy science will emerge. Here, we show that when immersed in ionic solution, a layer of graphene takes on new electrochemical properties that make it a trans-electrode. The trans-electrode's properties are the consequence of the atomic scale proximity of its two opposing liquid-solid interfaces together with graphene's well known in-plane conductivity. We show that several trans-electrode properties are revealed by ionic conductivity measurements on a CVD grown graphene membrane that separates two aqueous ionic solutions. Despite this membrane being only one to two atomic layers thick, we find it is a remarkable ionic insulator with a very small stable conductivity that depends on the ion species in solution.…"

[1006.1126] Body-and-cad Geometric Constraint Systems
"Motivated by constraint-based CAD software, we develop the foundation for the rigidity theory of a very general model: the body-and-cad structure, composed of rigid bodies in 3D constrained by pairwise coincidence, angular and distance constraints. We identify 21 relevant geometric constraints and develop the corresponding infinitesimal rigidity theory for these structures. The classical body-and-bar rigidity model can be viewed as a body-and-cad structure that uses only one constraint from this new class. As a consequence, we identify a new, necessary, but not sufficient, counting condition for minimal rigidity of body-and-cad structures: nested sparsity. This is a slight generalization of the well-known sparsity condition of Maxwell."

Shit happens, or how I learned to love the incident | The IT Skeptic
"This seems a reversal of some things I have said in the past about the need for change control. I said that "shit happens" is not an excuse any more. I still believe that. Just because some incidents will remain unpreventable doesn't mean that many others can't be prevented. Just because fixing a problem in one place means higher risks will be taken elsewhere doesn't mean we shouldn't fix the problems. And just because complex systems are impossible to stop breaking doesn't mean that there isn't negligence behind some breakages."

"Up until World War I, the archetypal manufacturing CEO was production oriented—usually an engineer or inventor of some kind. Even as late as the 1930s, business school curriculums focused mostly on production. Khurana notes that many schools during this era had mini-factories on campus to train future managers."

Make: Online : Open source hardware 2009 - The definitive guide to open source hardware projects in 2009
"Welcome to definitive guide to open source hardware projects in 2009. First up - What is open source hardware? These are projects in which the creators have decided to completely publish all the source, schematics, firmware, software, bill of materials, parts list, drawings and "board" files to recreate the hardware - they also allow any use, including commercial. Similar to open source software like Linux, but this hardware centric."

Open Design Projects
"Extensive research has been done to analyze the phenomenon of open source software development from various perspectives. By contrast little is known about open source development of tangible objects, so–called open design, so far. Until recently, limitations to the availability of successful empirical examples of this ‘new innovation model’ outside software may have been a key reason for this gap.

This paper contributes to the literature on the open source mode of product development by providing a quantitative study (N = 85) of open design projects. Our goal is to explore the landscape of open source development in the world of atoms, to analyze project characteristics, structures, and success, and to investigate similarities and dissimilarities to open source software development."

PhilSci Archive - The importance of pairwork in educational and interdisciplinary initiatives
"An early and prominent employee of Google, Georges Harik, recently made the assertion that pairs working together in startups are 20 times more productive than individuals working alone. The author has also personally experienced the boost of what is here termed pairwork in a university setting during the startup phase of several educational and interdisciplinary initiatives. The paper briefly explores pairwork in the history of technology and constructs both qualitative and little quantitative models of pairwork. The quantitative model under reasonable assumptions easily recovers Harik’s 20x boost. The paper also briefly examines the author’s recent experiences with pairwork in four interdisciplinary and educational initiatives."

Master Craftsman Teams.
"Why should a young aspiring software professional spend four years and $200K+ to attend an institution that will teach them less about their chosen profession than 3 months of working on a real project with talented mentors? Indeed, why should employers pay $50K for undertrained programmers who are sure to make horrific messes for the next three years of their career?

Consider instead a team of craftspeople. At the center of this team is a master programmer. This is someone who has been programming for two decades or more. This person understand systems at a gut level, and can quickly make technical judgements without agonizing over them. Such a person can direct a team with the kind of calm confidence that only comes with years of experience and seasoning."

Rands In Repose: The Makers of Things
"We are defined by what we build. It’s not just the engineering ambition that designed these structures, nor the 20 people who died building the Brooklyn Bridge. It’s that we believe we can and decide to act. I’m happy to report our new President agrees when he says,

“In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted — for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things — some celebrated but more often men and women obscure in their labor, who have carried us up the long, rugged path towards prosperity and freedom.”"

Open Source Hardware Hackers Start P2P Bank | Gadget Lab from Wired.com
"Lenders are offered returns based on a rolling six-month average so dud projects will be offset by sales of profitable ones. It takes just a few deals to strike it big, Huynh and Stack say, and because it is a community that is not just passionate but also knowledgeable, better projects are likely to get funded.

The promise of returns is enough to get former investment banker Andrew de Montille excited.

"I put money in the bank not because I consider it as a charitable investment," says de Montille. "Rather, I am very confident that some of the projects will do well enough to be profitable to the investors.""

"1) Rational solutions need not be universal, instead they will be only effective in appropriate contexts.

2) Rationally acceptable conclusions do not have to follow necessarily from the information given, as acceptance is not to be understood in terms of a formal relationship between propositions but in terms of a practical commitment.

3) The rationality of the conclusions is not necessarily determined by whether they conform to the appropriate rules, indeed the primary focus is removed from conclusions and placed upon actions that are taken on the basis of beliefs and methods that are all subject to further criticism and development.

"AMG is a multilevel technique for solving large-scale linear systems with optimal or near-optimal efficiency. Unlike geometric multigrid, AMG requires little or no geometric information about the underlying problem and develops a sequence of coarser grids directly from the input matrix. This feature is especially important for problems discretized on unstructured meshes and irregular grids."

Vacuum - Edward Vielmetti is on the move in Ann Arbor, Michigan 48104: Buckminster Fuller on making money vs. making sense
"Very frequently I hear or read of my artifacts adjudged by critics as being "failures," because I did not get them into mass-production and "make money with them." Such money-making-as-criteria-of-success critics do not realize that money-making was never my goal. I learned very early and painfully that you have to decide at the outset whether you are trying to make money or to make sense, as they are mutually exclusive."

Annuals converted into perennials
"VIB researchers, such as Siegbert Melzer in Tom Beeckman's group, have studied two such flower-inducing genes. They have deactivated them in thale cress (Arabidopsis thaliana), a typical annual. The VIB researchers found that mutant plants can no longer induce flowering, but they can continue to grow vegetatively or come into flower much later. Melzer had found that modified crops did not use up their store of non-specialised cells, enabling perennial growth. They can therefore continue to grow for a very long time.

As with real perennials these plants show secondary growth with wood formation creating shrub-like Arabidopsis plants."

Patent Law Blog (Patently-O): Co-Inventors Contribution Must Be “More Than The Exercise of Ordinary Skill”
"Correcting Inventorship: An issued patent is presumed to name the correct inventors. Thus, an inventorship challenge must bring "clear and convincing evidence" that the newly surfaced inventor "contributed to the conception of the claimed invention." "Simply reducing to practice that which has been conceived by others is insufficient for co-inventorship." Under the clear and convincing standard, the inventorship challenge "must be corroborated by independent evidence.""

Muck and Mystery: Wrong Ethic
"There are some efforts in progress to develop perennial grain producing grasses to overcome one of the costly and destructive characteristics of food plants: cultivation. The yearly need to break the soil to plant a crop is an expensive labor and material consuming activity, and it degrades soil. It's a non-trivial objective. A cross of some sort that produced perennial C4 grain producing grasses that are able to produce in a wider range of temperatures would be as revolutionary as earlier efforts that produced shorter grain plants that put more of their energy into seed than stalk."

Engineers create bone that blends into tendons
"They created the tissue by coating a three-dimensional polymer scaffold with a gene delivery vehicle that encodes a transcription factor known as Runx2. They generated a high concentration of Runx2 at one end of the scaffold and decreased that amount until they ended up with no transcription factor on the other end, resulting in a precisely controlled spatial gradient of Runx2. After that, they seeded skin fibroblasts uniformly onto the scaffold. The skin cells on the parts of the scaffold containing a high concentration of Runx2 turned into bone, while the skin cells on the scaffold end with no Runx2 turned into soft tissue. The result is an artificial bone that gradually turns into soft tissue, such as tendons or ligaments."

Conceptual Trends and Current Topics
Graham describes his strategy precisely: "Find (a) simple solutions (b) to overlooked problems (c) that actually need to be solved, and (d) deliver them as informally as possible, (e) starting with a very crude version 1, then (f) iterating rapidly." That seems simple, but it is not. He elaborates:

When I first laid out these principles explicitly, I noticed something striking: this is practically a recipe for generating a contemptuous initial reaction. Though simple solutions are better, they don't seem as impressive as complex ones.
