How to Prepare for the Next Recession: Automate the Rescue Plan

San Diego 4h ago
As someone with an engineering background (both education and mindset) this kind of simplistic design of complex systems is very concerning.

How to build a better future: high-tech Jenga at the Soane Museum
December 21, 2018 | Financial Times | Simon Ings.

Suspended from four wires, this digitally controlled cable robot is building something out of hand-size wooden blocks. It’s a slow beast. Hours must pass before its construction becomes recognisable: a dome, of the sort that John Soane produced for the Bank of England and Dulwich Picture Gallery.

Polibot does not look like a game changer. But according to Arthur Mamou-Mani, whose architectural practice built it, Polibot’s children are going to change the world.......in the early 2000s, computer-generated design was a fairly dry topic. Patrik Schumacher, principal of Zaha Hadid Architects, dubbed it “parametricism”, reflecting the way programmes evolve forms according to a set of parameters........Through experiments in robotics, Mamou-Mani’s practice is out to develop new ways of building that will make architecture, engineering and construction merge into single field. The point is not what Polibot is, but what it could become. It’s not just a pick-and-place machine. It’s the early prototype of a universal builder.....There have been many experiments in the large-scale 3D printing of buildings. But the kinds of industrial robot arms that are usually employed for this work are far too cumbersome and delicate to wheel on to a building site....Gigantic robot arms will never spew out skyscrapers at a single sweep, Mamou-Mani says, for the simple reason that it would make construction less, not more efficient....construction is mostly about bringing big chunks of stuff together,” he says. “Currently, concrete is still the material of choice for the construction industry, but we’re slowly switching to timber, and this will be a massive revolution, because once you start working with timber, you’re no longer casting anything on site. You’re thinking entirely in terms of prefabrication and assembly.”Mamou-Mani dreams of building simple towers from elements (“prefabricated properly, by robotic arms, like cars”) assembled on site by gigantic Polibots....Mamou-Mani explains his vision of buildings that can expand and contract, depending on the economy....Why do we think that permanence is necessary?” Elsewhere in the show, the wall text proclaims that “the best cities are the ones that don’t leave ruins”....All great advances in industrial culture are prefigured by model-making.

Meet the SEC’s Brainy New Crime Fighters - WSJ
By SCOTT PATTERSON
Updated Dec. 14, 2014

The SEC is mustering its mathematical firepower in its Center for Risk and Quantitative Analytics, which was created last year soon after Mary Jo White took charge of the agency to help it get better at catching Wall Street misconduct. The enforcement unit, led by 14-year SEC veteran Lori Walsh, is housed deep within the warrens of the SEC’s Washington headquarters, and staffed by about 10 employees trained in fields such as mathematical finance, economics, accounting and computer programming.

Ms. Walsh says access to new sources of data and new ways of processing the data have been key to finding evidence of wrongdoing. “When you look at data in different ways, you see new things,” she said in an interview

WWE champ, fitness goddess Trish Stratus shares how she kicks butt - The Globe and Mail
Sep. 21 2014 | The Globe and Mail | COURTNEY SHEA.

Here, some of her other secrets to success.

(1) The calm in the middle of the ring. Take time every day to disconnect is so important for having perspective. For Trish Stratus, hot yoga is her stress-eliminating device.

(2) Preparedness is a weapon. Trish's mentor, Robert Kennedy,the then publisher of magazines Oxygen and MuscleMag, gave her the opportunity to do a photo shoot. He told her about it two months in advance, set her up with a trainer and said, “Go get ready for it.” Trish's formula for success, is "preparedness meets opportunity". Many people are given opportunities in life, but they aren’t able or willing to prepare for them. Opportunities happen more often then you think but you have to be ready for them.

(3) I am woman, hear me headlock. Setbacks occur, but keep busting your butt out there, keep working, keep working, and eventually people will realize and recognize your contribution. Sometimes having to overcome hurdles is also a chance to make a mark.

(4) To get it right, write it down. Take notes. Make (to-do) lists. Keeping track of things can enhance awareness, mindfulness, and even inspiration.

(5) Authenticity matters (even in scripted wrestling). The best wrestlers– the ones that have longevity and resonate most with the audience – are almost always when it’s an amped-up version of the actual personality.

Big Data Is Great, but Don’t Forget Intuition
December 29, 2012 | NYTimes.com |By STEVE LOHR.

A major part of managing Big Data projects is asking the right questions: How do you define the problem? What data do you need? Where does it come from? What are the assumptions behind the model that the data is fed into? How is the model different from reality?...recognize the limits and shortcomings of the Big Data technology that they are building. Listening to the data is important, they say, but so is experience and intuition. After all, what is intuition at its best but large amounts of data of all kinds filtered through a human brain rather than a math model?

globeadvisor.com: Living in the real world of finance
December 9, 2011 | G&M | by David Parkinson.
Both a scientist and financial guru, Emanuel Derman warns of relying on mathematical models to predict stock movements. As David Parkinson reports, investors should beware the wild card of human nature...Mr. Derman was in Toronto discussing his new book, Models. Behaving. Badly: Why Confusing Illusion With Reality Can Lead to Disaster, on Wall Street and in Life.

New approaches to quantifying the spread of infect... [Nat Rev Microbiol. 2005] - PubMed result
Traditional approaches to mathematical modelling of infectious
diseases deal most effectively with large outbreaks in large
populations. The desire to elucidate the highly variable dynamics of
disease spread amongst small numbers of individuals has fuelled the
development of models that depend more directly on surveillance and
contact-tracing data. This signals a move towards a closer interplay
between epidemiological modelling, surveillance and disease-management
strategies.
