A map of the Tricki

A map of the Tricki
This is an attempt to give a quick guide to the top few levels of the Tricki. It may cease to be feasible when the Tricki gets bigger, but we might perhaps be able to automate additions to it. Clicking on arrows just to the right of the name of an article reveals its subarticles. If you want to hide the subarticles again, then you should click to the right of them rather than clicking on the name of one of the subarticles themselves, since otherwise you will follow a link to that subarticle.

Living and Working Abroad Para leér esta entrada en Español píque aquí *************************************************************************************************************** This is not some theoretical piece about how you might do if you decide to live and work abroad. I’ve been ‘doing it’ for more than 30 years now, it was in 1980 that I left my home country, Germany, and in all humility, I am an expert. I spent seven month in India, lived three years in Greece, another three years in England, and I have been living in Mexico for the past 20 odd years.The years in between I roamed the world. I have not been with any multinational company that sent me to those places. When I started off I didn’t have a profession. I started to develop myself at the beginning of the nineties as a language teacher, since by then I spoke several languages. Let me tell you right from the start, it wasn’t easy. But looking back over the past 30 odd years, I wouldn’t change my life for anything else. Find out for yourself.

(1) What is it like to have an understanding of very advanced mathematics View model The TEAF Matrix of Views and Perspectives. A view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture. A view is a representation of a whole system from the perspective of a related set of concerns.[1][2] Since the early 1990s there have been a number of efforts to prescribe approaches for describing and analyzing system architectures. Usually a view is a work product that presents specific architecture data for a given system. Overview[edit] The purpose of views and viewpoints is to enable humans to comprehend very complex systems, to organize the elements of the problem and the solution around domains of expertise and to separate concerns. Most complex system specifications are so extensive that no single individual can fully comprehend all aspects of the specifications.

Google To Develop ISP Throttling Detector Update: The news story below was originally posted on Friday, June 13. It is a brief summary of a longer news article written by Cade Metz of The Register. After our article posted we were contacted by Technology Consultant George Ou, who was briefly referenced in our news story. Ou felt that Metz's coverage--and therefore our coverage as well--did not accurately represent his statements or some of the arguments for network prioritization. Google has been very vocal on its stance for net neutrality. "We're trying to develop tools, software tools...that allow people to detect what's happening with their broadband connections, so they can let [ISPs] know that they're not happy with what they're getting -- that they think certain services are being tampered with," Google senior policy director Richard Whitt said this morning during a panel discussion at Santa Clara University, an hour south of San Francisco. "We were pretty well known on the internet.

7 lines of code, 3 minutes: Implement a programming language A small (yet Turing-equivalent) language The easiest programming language to implement is a minimalist, higher-order functional programming language known as the lambda calculus. The lambda calculus actually lives at the core of all the major functional languages--Haskell, Scheme and ML--but it also lives inside JavaScript, Python and Ruby. It's even hiding inside Java, if you know where to find it. A brief history Alonzo Church developed the lambda calculus in 1929. Back then, it wasn't called a programming language because there were no computers; there wasn't anything to "program." It was really just a mathematical notation for reasoning about functions. Fortunately, Alonzo Church had a Ph.D. student named Alan Turing. Alan Turing defined the Turing machine, which became the first accepted definition of a general-purpose computer. What makes this remarkable is that there are only three kinds of expressions in the lambda calculus: variable references, anonymous functions and function calls.

There’s more to mathematics than rigour and proofs The history of every major galactic civilization tends to pass through three distinct and recognizable phases, those of Survival, Inquiry and Sophistication, otherwise known as the How, Why, and Where phases. For instance, the first phase is characterized by the question ‘How can we eat?’, the second by the question ‘Why do we eat?’ and the third by the question, ‘Where shall we have lunch?’ One can roughly divide mathematical education into three stages: The “pre-rigorous” stage, in which mathematics is taught in an informal, intuitive manner, based on examples, fuzzy notions, and hand-waving. The transition from the first stage to the second is well known to be rather traumatic, with the dreaded “proof-type questions” being the bane of many a maths undergraduate. It is of course vitally important that you know how to think rigorously, as this gives you the discipline to avoid many common errors and purge many misconceptions.

DiffRank Omar Odibat and Chandan K. Reddy Networks have been extensively used to model various complex systems such as online social networks, co-authorship and citation networks and gene networks. Due to different kinds of variations such as temporal, spatial, topic and phenotypic variations, several variants of the same network may exist. For several practical problems, identifying the nodes that are changing between the networks provide vital information regarding the dynamics of the network states. Here, we propose a novel ranking algorithm, DiffRank, which ranks the nodes of two networks based on their differential behavior between the two networks. We demonstrate the effectiveness of DiffRank on synthetic and real datasets. In scientific co-authorship networks, the nodes are authors of academic papers and the edges represent co-authorship (or collaboration) relationships between the authors. Omar Odibat, Chandan K.

Grid Paper PDFs Downloadable and very printable, I find these PDFs extremely useful. Graph Paper Quick Picks Now set to: 8 1/2 x 11 Paper. Ruled in Inches. Now set to: A4 Paper, Ruled in Millimeters. Custom Graph Papers Need more specific stuff? Tip number one! Though I do return the correct header for a PDF, sometimes Explorer gets confused when downloading... Tip number two! Some people may need to turn off the option in Adobe's Acrobat reader "shrink to fit" which may resize the grid slightly to fit your printer's printable area. Tip number three! If you want the hexes aligned with the other edge of the paper, just make your paper size "11 x 8.5" and print the result in landscape mode!
