The Life of a South Central Statistic | The New Yorker
What sets the course of a life? Three years before my beloved cousin’s murder—before the weeping, before the raging, before the heated self-recriminations and icy reckonings—I awoke with the most glorious sense of anticipation I’ve ever felt. It was June 29, 2006, the day that Michael was going to be freed. Outside my vacation condo in Hollywood, I climbed into the old white BMW I’d bought from my mother and headed to my aunt’s small stucco home, in South Central. On the corner, a fortified drug house stood like a sentry, but her pale cottage seemed serene, aglow in the morning sun. Poverty never looks quite as bad in the City of Angels as it does elsewhere.

She Just Won 3 Gold Medals for Her Swimming. She’s Only 73. - The New York Times
“Our bodies are made for being used,” she said. “Physical fitness and activity improves brain function. Anyone who is keeping up physical activity — both the aerobic part, which is really important, and the strength and balance and flexibility — is reducing the risks and buffering the decline that is going on.”

For Mr. Cheek, the nation’s fastest 100-meter sprinter in his age group, there is “a pride and a mental discipline that carries over into your whole lifestyle,” he said. Consistent exercise, said Mr. Cheek, who is a part-time professor of social psychology at California State University, Fresno, allows you to have “a body that can perform for you any time you want.”

What happened to Trump's war on data?
Straightforward as “data collection” may sound, in practice there’s often a strong political component to government data. What information to collect, about whom and how it’s collected are critical questions that don’t always have one objective answer. “Data is inherently political,” said Wonderlich. “And how it’s used depends on who’s collecting it and what they’re representing about the world.”

Sometimes, those questions fall on Congress, such as when lawmakers created the unemployment rate—as unbiased a statistic as exists today—in the 1930’s. According to a history of the U.S. Census, the unemployment rate was the subject of a fierce political fight upon its creation, including how often to collect data on unemployment and who would be counted as unemployed. President Herbert Hoover and his allies thought that the crude unemployment figures, which came from limited Bureau of Labor Statistics surveys and business reports at the time, were adequate measures during the Great Depression. Democrats and many labor economists disagreed and called for additional surveys to determine the true extent of unemployment—and the federal response necessary to alleviate it.

Improving the Realism of Synthetic Images - Apple Machine Learning Journal
Most successful examples of neural nets today are trained with supervision. However, to achieve high accuracy, the training sets need to be large, diverse, and accurately annotated, which is costly. An alternative to labelling huge amounts of data is to use synthetic images from a simulator. This is cheap as there is no labeling cost, but the synthetic images may not be realistic enough, resulting in poor generalization on real test images. To help close this performance gap, we’ve developed a method for refining synthetic images to make them look more realistic. We show that training models on these refined images leads to significant improvements in accuracy on various machine learning tasks.

The limitations of deep learning
The most surprising thing about deep learning is how simple it is. Ten years ago, no one expected that we would achieve such amazing results on machine perception problems by using simple parametric models trained with gradient descent. Now, it turns out that all you need is sufficiently large parametric models trained with gradient descent on sufficiently many examples. As Feynman once said about the universe, "It's not complicated, it's just a lot of it".

In deep learning, everything is a vector, i.e. everything is a point in a geometric space. Model inputs (it could be text, images, etc) and targets are first "vectorized", i.e. turned into some initial input vector space and target vector space. Each layer in a deep learning model operates one simple geometric transformation on the data that goes through it. Together, the chain of layers of the model forms one very complex geometric transformation, broken down into a series of simple ones. This complex transformation attempts to maps the input space to the target space, one point at a time. This transformation is parametrized by the weights of the layers, which are iteratively updated based on how well the model is currently performing. A key characteristic of this geometric transformation is that it must be differentiable, which is required in order for us to be able to learn its parameters via gradient descent. Intuitively, this means that the geometric morphing from inputs to outputs must be smooth and continuous—a significant constraint.

The whole process of applying this complex geometric transformation to the input data can be visualized in 3D by imagining a person trying to uncrumple a paper ball: the crumpled paper ball is the manifold of the input data that the model starts with. Each movement operated by the person on the paper ball is similar to a simple geometric transformation operated by one layer. The full uncrumpling gesture sequence is the complex transformation of the entire model. Deep learning models are mathematical machines for uncrumpling complicated manifolds of high-dimensional data.

Automatically generate beautiful visualizations from your data
And other bad ideas

I work in data visualization, a loosely defined and rapidly evolving field that is generally about taking data and turning it into something people can understand. There are a lot of different tools and disciplines involved in doing so, and it is impacting almost every field of study, industry and business. I believe it is essentially a new medium for communication, and we are still very much in the formative stages of its development.

Cafe Cracks: Attacks on Unsecured Wireless Networks
Mobile users demand high connectivity in today's world, often at the price of security. Requiring Internet access at the airport, public buildings, and restaurants, users will easily sacrifice a secure connection for a fast and reliable one. By broadcasting rogue access points at these compromising locations, crackers can launch effective Man-in-the-Middle attacks. Our developed crack, Cafe Crack, provides a platform built from open source software for deploying rogue access points and sophisticated Man-in-the-Middle attacks. Built around the Untangle Server software, Cafe Crack allows the hacker to dynamically measure, monitor and redirect network traffic. This paper will provide an example of DNS spoofing using the Cafe Crack platform and then provide simple and effective protection techniques against harmful rogue AP attacks.

Tracking Campaign Cash in Colorado - Columbia Journalism Review
It was a nightmare. You have to print out every single (independent expenditure) committee filing, and go through it by hand. You might have a committee that spent $800,000, and a lot of the money is in $200 increments spread over 20 races, and you have to add those with your little hand held calculator. There are 24 races in total across the state, so I had to add up for each committee what they spent on each race and then add all that up on both sides. It was a really time-consuming and tedious job.

We’re downloading the data onto our website, and one reason we’re doing that is because of the issues some people have had accessing the Secretary of State’s website—we think it’s a public service. We have the 2010 contributions up there, but hopefully in the next two months we’ll have up the 2010 expenditures, then the 2008 contributions and expenditures, and hopefully we’re going to be able to keep this going for the year.

In TV Ratings Game, Networks Try to Dissguys Bad Newz from Nielsen - WSJ
Walt Disney Co.’s ABC declined to comment. The network, though, groused last month when NBC News intentionally misspelled an entire week of “Nightly News” broadcasts. Altogether, NBC, which is ranked second behind ABC in ratings, has played the misspell card 14 times since the start of the 2016-17 television season last fall.

NBC News said it broke no rules. “As is standard industry practice, our broadcast is retitled when there are pre-emptions and inconsistencies or irregularities in the schedule, which can include holiday weekends and special sporting events,” a show spokesman said.

Preferential Rents in New York City - ProPublica Data Store
In 2003, lawmakers in New York State passed a law that in effect allowed landlords to bypass annual limits on rent increases for their rent-stabilized apartments. Owners could raise rents by more than the annual limits if they registered a high rent — often high above existing market rates -- but charged tenants a lower, “preferential” rent. Preferential rents are not regulated and can be raised up to the registered rate upon lease renewal. Today, more than 250,000 New York City apartments feature these rents.

Laurence Tratt: What Challenges and Trade-Offs do Optimising Compilers Face?
After immersing oneself in a research area for several years, it's easy to feel like the heir to a way of looking at the world that is criminally underrated: why don't more people want what I want? This can be a useful motivation, but it can also lead to ignoring the changing context in which most research sits. So, from time to time, I like to ask myself the question: “what if everything I believe about this area is wrong?” It’s a simple question, but hard to answer honestly. Mostly, of course, the only answer my ego will allow me is “I can’t see anything I could be wrong about”. Sometimes I spot a small problem that can be easily fixed. Much more rarely, I've been forced to acknowledge that there’s a deep flaw in my thinking, and that the direction I’m heading in is a dead-end. I’ve twice had to face this realisation, each time after a gradual accumulation of unpleasant evidence that I've tried to ignore. While abandoning several years work wasn’t easy, it felt a lot easier than trying to flog a horse I now knew to be dead.

Human error costs TransAlta $24-million on contract bids - The Globe and Mail
A slip of the hand in a computer spreadsheet for bidding on electricity transmission contracts in New York will cost TransAlta Corp. $24-million (U.S.), wiping out 10 per cent of the company's profit this year.

The error, although costly, was bizarrely simple. Someone preparing the electronic file of bids that TransAlta submitted at the end of April misaligned the rows of information in the spreadsheet. High bids intended for certain transmission paths were instead made for lower-demand routes -- meaning that TransAlta overpaid for transmission contracts, as well as buying more capacity than it intended in certain cases.

"It was literally a cut-and-paste error in an Excel spreadsheet that we did not detect when we did our final sorting and ranking of bids prior to submission," said Steve Snyder, TransAlta's president.

Excel Error by a Cleary Gottlieb Associate Alters Lehman Asset Deal
A first-year associate at Cleary Gottlieb Steen & Hamilton made an Excel reformatting error that mistakenly added 179 contracts to an agreement to buy Lehman Brothers assets, according to a motion filed with a New York bankruptcy court on Friday.

Cleary Gottlieb Steen & Hamilton represents Barclays Capital Inc. in its agreement to buy the assets. Its motion (PDF posted by Above the Law) says the law firm was working under a tight deadline when the mistake was made, Computerworld reports.

The motion seeks to exclude the 179 contracts from the purchase agreement.

Above the Law was the first to report the error. Its story said the mistake happened at around 11:30 p.m. on Sept. 18 when a second-year associate asked a first-year associate to reformat an Excel document of critical Lehman contracts to be assumed by Barclays.

The associate resized the rows when converting the spreadsheet into a PDF document, causing “hidden” contracts in the spreadsheet to be exposed. The spreadsheet, which had been e-mailed to the law firm by a Lehman representative, contained nearly 1,000 rows and more than 24,000 individual cells.

Inside the Algorithm That Tries to Predict Gun Violence in Chicago - The New York Times
https://data.cityofchicago.org/Public-Safety/Strategic-Subject-List/4aki-r3np399,0

Gun violence in Chicago has surged since late 2015, and much of the news media attention on how the city plans to address this problem has focused on the Strategic Subject List, or S.S.L.

The list is made by an algorithm that tries to predict who is most likely to be involved in a shooting, either as perpetrator or victim. The algorithm is not public, but the city has now placed a version of the list — without names — online through its open data portal, making it possible for the first time to see how Chicago evaluates risk.

We analyzed that information and found that the assigned risk scores — and what characteristics go into them — are sometimes at odds with the Chicago Police Department’s public statements and cut against some common perceptions.

Making the Internet Archive’s full text search faster.
This article describes how we made the full-text organic search faster at the Internet Archive — without scaling horizontally — allowing our users to search in just a few seconds across our collection of 35 million documents containing books, magazine, newspapers, scientific papers, patents and much more.

By organic search we mean the “method for entering one or a plurality of search items in a single data string into a search engine. Organic search results are listings on search engine results pages that appear because of their relevance to the search terms.” (1).

The relevance should be scored on the search query matches for every document. In other words, if the search query has a perfect match in some of our documents, we want to return these documents; otherwise, we want to return the documents containing a part of the query or one of its subset.

Failure to warn: Hundreds died while taking an arthritis drug, but nobody alerted patients
In a review of millions of reports to the FDA involving more than 100 drugs approved since 2010, Actemra stood out. It showed that Actemra patients had experienced an unusually large number of serious side effects that didn’t appear on the drug’s warning label.

The initial review was performed for STAT by Advera Health Analytics in Santa Rosa, Calif., a company that collects and curates drug-related complaints to the FDA Adverse Events Reporting System, known as FAERS. The company then provided comparison data for all major rheumatoid arthritis drugs.

STAT’s analysis of that data, including more than 13,500 FAERS reports on Actemra, showed higher than expected numbers of several serious problems when compared to competing drugs. These included the blockbusters Humira and Remicade, which have many more users.
