We’re living in the now, we no longer have a sense of future direction, and we have a completely new relationship to time. In this Wired Q&A between author of Present Shock Rushkoff and former editor in chief of cyberpunk magazine Mondo 2000 R.U. - We’re living in the now, we no longer have a sense of future direction, and we have a completely new relationship to time. That’s the premise of Douglas Rushkoff’s latest book Present Shock: When Everything Happens Now, a sort-of update to Alvin Toffler’s influential Future Shock from decades ago. I met Rushkoff back when I was editor of the cyberpunk magazine Mondo 2000, when he was working on his first book about digital culture. But the original publishers canceled that book, thinking the internet was a fad and would be over by the time it hit stands. And even when it was finally published, its potential readership was still limited. The internet is still with us (to put it mildly) … so Rushkoff’s latest book is for everybody. Throughout the intervening years, Rushkoff and I have been in a dialogue about technology, culture, and the future that, in some ways, has never really stopped. So here we are, continuing that conversation; only now, the challenge we’re discussing is “presentism” — What happens when the future is here, now? R.U. Sirius: You describe five symptoms — pathologies, really — of “presentist” culture. One of these is “narrative collapse.” Can you explain it for those who haven’t read the book? Douglas Rushkoff: Narrative Collapse is what happens when we no longer have time in which to tell a story. Via Wildcat2030 Delete the scoop?

Être journaliste scientifique ne doit pas être facile. J’imagine qu’il faut être à l’écoute des nouvelles scientifiques, et d’informer, aussi justement que possible. C’est ce que fait avec brio Pierre Barthélémy (aka@PasseurSciences sur Twitter) dans sa chronique hebdomadaire sélection scientifique de la semaine. Il essaye ainsi de parler de sciences dans un journal qui a (trop) souvent confondu science et technologie (technologie étant aussi souvent un mot savant utilisé pour masquer de la publicité pour des appareils technologiques avancés). Et comme l’espace qui lui est imparti est restreint (c’est le moins qu’on puisse dire), la plupart des informations passent par son blog http://passeurdesciences.blog.lemonde.fr/, qui est riche ! Sylvestre Huet fait aussi ce travail pour Libération, avec son blog http://sciences.blogs.liberation.fr/(là; encore, on peut lire bien plus de choses en ligne que que dans la version papier, ce qui est d’autant plus intéressant pour les lecteurs de l’autre coté de l’océan atlantique). Sylvestre Huet arrive à parler géologie, puis démographie, avant d’évoquer dans un article truffé de références les réformes des instances qui régentent la recherche en France. Oui, les deux blogs sont malgré tout très français. Pour une vision plus internationale, on pourra citer l’admirable travail de Pascal Lapointe, par exemple (aka @paslap) surhttp://sciencepresse.qc.ca/. Delete the scoop?

Offshore leaks is the name of a financial scandal that unmasked details of 130,000 offshore accounts in April 2013. Some observers have called it the biggest hit against international tax fraud of all times, although it has been pointed out that normal businesses may use the offshore legislation to ease formalities in international trade.[1][2] The report uncovered the offshore assets of people from 170 countries and territories.[2] It is estimated that 21 to 31 trillion dollars are hidden in offshore localities which corresponds to the economies of the USA and Japan combined. 86 journalists from 46 countries were a part of the investigations including the BBC, The Guardian, the Washington Post, Le Monde, the SonntagsZeitung and the Süddeutsche Zeitung.[3] Imee Marcos, daughter of the former Philippine president Ferdinand Edralin Marcos, is on the list. Philippine authorities are investigating if the money is part of the 5 billion dollars with which Marcos fled from the country in the 1980s.[2] Peer Steinbrück has called for harsh penalties for the banks involved in the scandal, up to the revoking of banking licenses.[4]

L'EFF veut mettre les trolls en cage. Mais pas n'importe lesquels. L'organisation cible tout particulièrement les trolls de brevet (patent trolls), qui s'attaquent aux startups et aux PME pour leur extorquer de l'argent en les menaçant de les poursuivre en justice au nom de leur supposée propriété industrielle bafouée. L'EFF réclame l'intervention de la FTC. Via Pierre Breese, Lockall
luiy's insight:
Selon ses estimations, les plaintes américaines impliquant des brevets sont dominés (61 %) par les trolls. En 2007, les trolls représentaient 27 % des actions en justice. En 2011, 45 %. Un cinquième des startups levant entre 20 et 50 millions de dollars a déjà eu à faire avec un troll des brevets. Entre 50 et 100 millions de dollars, c'est 35 % des startups qui sont concernées.
Loin de se résorber, le problème s'aggrave, au risque de freiner l'innovation, de contribuer à la crise économique et financière, tandis que la qualité des vérifications des demandes réalisée par les bureaux comme l'USPTO aux États-Unis, l'Office Européen des Brevets ou l'institut national de la propriété industrielle en France diminue au moment où celles-ci explosent.
Cependant des initiatives comme la vérification collaborative ont émergé au Royaume-Uni et aux USA, tandis que certaines firmes, comme Google par exemple, réclame une réforme du droit des brevets. Il faut également noter la mobilisation de l'Electronic Frontier Foundation (EFF). L'ONG demande à la commission fédérale américaine (FTC)de prendre des mesures pour faire cesser ces pratiques.
"Nous invitons urgemment la FTC à produire un rapport détaillé sur les trolls de brevet et le coût qu'ils imposent à l'économie. [...] Les trolls coûtent des milliards de dollars chaque année et représentent un fardeau particulièrement lourd sur les startups. Les trolls de brevet les ciblent parce qu'ils savent que ce sont des petites structures manquant de ressources pour contre-attaquer".
"Nous pressons également la FTC d'utiliser ses pouvoirs d'investigation et d'application de la loi contre les trolls de brevet les plus zélés, en particulier ceux qui utilisent des plaintes sans fondement pour extorquer des accords à l'amiable. Parce que ces coquilles vides ne font rien elles-mêmes, elles n'ont généralement rien à perdre. Cela leur donne une occasion unique d'abuser du système [...]". Delete the scoop?

Data Visualization – it's one of the unsung heroes in the Big Data picture, but that appears to be changing. Seattle-based data visualization company Tableau Software filed its IPO statement with the U.S. Via Cho Dong Hwan
luiy's insight:
This attention to performance and features was accentuated by the company’s latest product release, Tableau 8.0. The product remains true to enterprise capabilities and adds a few new ones including real-time processing for multiple data points, the ability to query Google BigTable data sets, and a direct connection into Google Analytics. The release is not without critics however as blogger Stephen Few shared his take on the release.
One thing for sure, Tableau is evolving and as Kristen Nicole noted there’s a lot of adoption taking place and some are looking at this as the “new BI”. Delete the scoop?

CrossfilterFast Multidimensional Filtering for Coordinated Views
Crossfilter is a JavaScript library for exploring large multivariate datasets in the browser. Crossfilter supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; we built it to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly. Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the performance of live histograms and top-Klists. For more details on how Crossfilter works, see the API reference. Example: Airline on-time performanceThe coordinated visualizations below (built with D3) show nearly a quarter-million flights from early 2001: part of the ASA Data Expo dataset. The dataset is 5.3MB, so it might take a few seconds to download. Click and drag on any chart to filter by the associated dimension. The table beneath shows the eighty most recent flights that match the current filters; these are the details on demand, anecdotal evidence you can use to weigh different hypotheses. Some questions to consider: How does time-of-day correlate with arrival delay? Arelonger or shorter flights more likely to arrive early? What happened on January 12? How do flight patterns differ between weekends and weekdays, or mornings and nights? Fork this example and try your own data! Delete the scoop?

While the information contained in these resources is a great guide and reference, the best way to become a data scientist is to make, create, and share! ENVIRONMENTWhile the emerging field of data science is not tied to any specific tools, there are certain languages and frameworks that have become the bread and butter for those working in the field. We recommend Python as the programming language of choice for aspiring data scientists due to its general purpose applicability, a gentle (or firm) learning curve, and — perhaps the most compelling reason — the rich ecosystem of resourcesand libraries actively used by the scientific community. DEVELOPMENTWhen learning a new language in a new domain, it helps immensely to have an interactive environment to explore and to receive immediate feedback.IPython provides an interactive REPL which also allows you to integrate a wide variety of frameworks (including R) into your Python programs. STATISTICSIt is often said that a data scientist is someone who is better at software engineering than a statistician and better at statistics than any software engineer. As such, statistical inference underpins much of the theory behind data analysis and a solid foundation of statistical methods and probability serves as a stepping stone into the world of data science.

Far from slowing, the market for fake Twitter followers seems to be taking off. Despite efforts by Twitter to check for fake accounts, the underground market is becoming more sophisticated.
luiy's insight:
Far from slowing, the market for fake Twitter followers seems to be taking off.
The fake Twitter follower phenomenon made headlines last summer after Mitt Romney’s Twitter following jumped by 100,000 in a matter of days. That news inspired a number of social media management companies like StatusPeople and SocialBakers to develop Web tools that try to determine what percent of a person’s Twitter followings are fake.
But those sites have hardly deterred people from dealing in the market for fake followers and fake retweets. The market is also becoming more sophisticated. In many cases, high-quality false Twitter accounts are nearly impossible to discern from the real thing. Those that sell them claim that they can make up to a million dollars in one week.
Andrea Stroppa and Carlo De Micheli, two Italian security researchers, spent the last several months investigating the underground economy for Twitter followers and said they had found a thriving market.
There are now more than two dozen services that sell fake Twitter accounts, but Mr. Stroppa and Mr. De Micheli said they limited themselves to the most popular networks, forums and Web sites, which include Fiverr, SeoClerks, InterTwitter, FanMeNow, LikedSocial, SocialPresence and Viral Media Boost. Based on the number of accounts for sale through those services — and eliminating overlapping accounts — they estimate that there are now as many as 20 million fake follower accounts....

What does twitter tell us about our social unconscious? Studies are just beginning to scratch the surface of the meaning behind the cacophony of noise we humans put online, but what might be the meaning behind this collective activity? Via Aaron Balick
luiy's insight:
The coolest I’ve found yet (thanks to David Patman) has been the We Feel Fine project defined as “an exploration of human emotion, in six movements. This project searches weblogs across the world for words associated with the statements “I feel” and “I am feeling” and records the feeling associated with that statement”. To quote from their website:
There is a stunning graphic in which you can see, in real time, groupings and clusterings of feelings as they occur. Interestingly, you can filter your searches by feeling, gender, age, weather, location or date, and then view your search in a variety of visually interesting ways. When I looked at it at 8:55 on Tuesday morning the 3rd of July I could see that in Britain the dominant feeling was “better” (circa 130,000 people) followed by “bad” (93,000 then) “good” (77,000). By clicking on individual nodes, you can even gain access to the original text. By doing this, you can get a great deal of detail about the context, as well as the feeling tone. The creators Jonathan Harris and Sep Kamvar should be highly commended for this work. Delete the scoop?

luiy's insight:
Five years ago, few people had heard the phrase “Big Data.” Now, it’s hard to go an hour without seeing it. In the past several months, the industry has been mentioned in dozens of New York Times stories, in every section from metro to business. (Wired has even already declared it passé: “STOP HYPING BIG DATA AND START PAYING ATTENTION TO ‘LONG DATA’.”) At least one corporation, the business-analytics firm SAS, has a Vice-President of Big Data. Meanwhile, nobody seems quite sure exactly what the phrase means, beyond a general impression of the storage and analysis of unfathomable amounts of information, but we are assured, over and over, that it’s going to be big. Last summer, Jon Kleinberg, a computer scientist at Cornell, said in the Times that “The term itself is vague, but it is getting at something that is real… Big Data is a tagline for a process that has the potential to transform everything.” Most of what’s written about Big Data is enthusiastic, like Kenneth Cukier and Viktor Mayer-Schonberger’s gushing ode “Big Data: A Revolution That Will Transform How We Live, Work, and Think,” which is currently selling briskly on Amazon, or the recent Times article on Mayor Bloomberg’s geek squad, and how “Big Data’s moment, especially in the management of cities, has powerfully and irreversibly arrived.” But despite the sense of excitement and promise surrounding the industry, Big Data isn’t nearly the boundless miracle that many people seem to think it is.

"“People in our model do not behave irrationally,” explains Grund, but while the “homo economicus” optimizes its utility independently, the “homo socialis” puts himself or herself into the shoes of others to consider their interests as well.” Helbing adds: “This establishes something like “networked minds”. Everyone’s decisions depend on the preferences of others.” This becomes even more important in our networked world." Via Howard Rheingold
luiy's insight:
A participatory kind of economy How will this change our economy? Today, many customers doubt that they get the best service by people who are driven by their own profits and bonuses. “Our theory predicts that the level of other-regarding preferences is distributed broadly, from selfish to altruistic. Academic education in economics has largely promoted the selfish type. Perhaps, our economic thinking needs to fundamentally change, and our economy should be run by different kinds of people,” suggests Grund. “The true capitalist has other-regarding preferences,” adds Helbing, “as the “homo socialis” earns much more payoff.” This is, because the “homo socialis” manages to overcome the downwards spiral that tends to drive the “homo economicus” towards tragedies of the commons. The breakdown of trust and cooperation in the financial markets back in 2008 might be a good example.
“Social media will promote a new kind of participatory economy, in which competition goes hand in hand with cooperation,” believes Helbing. Indeed, the digital economy’s paradigm of the “prosumer” states that the Internet, social platforms, 3D printers and other developments will enable the co-producing consumer. “It will be hard to tell who is consumer and who is producer”, says Christian Waloszek. “You might be both at the same time, and this creates a much more cooperative perspective.” 
Howard Rheingold's curator insight,
April 6, 4:28 AM
The woman in the picture is the late Elinor Ostrom, whose research is cited, but who did not contribute to the evolutionary modeling research that provides evidence for mechanisms whereby cooperative behavior can spread in socieities dominated by selfishness. Sociality is the key -- pewople who get to know each other can be stimulated by ordinarily disadvantaged cooperative actors into mutual cooperation, which then becomes self-reinforcing through mutual payoffs. The social web is certainly a hotbed of ill-will. It is also an environment in which those who are inclined to cooperate -- people with diseases or caregivers, gamers, makers, educators, and just friendly, civil people -- can find each other and cluster. It is that clustering that promotes payoffs and spreads cooperation, and which online social networks can promote. Delete the scoop?
