Teaching algorithms not to discriminate | Tampa Bay Times - 0 views

  • Algorithms have become one of the most powerful arbiters in our lives. They make decisions about the news we read, the jobs we get, the people we meet, the schools we attend and the ads we see. Yet there is growing evidence that algorithms and other types of software can discriminate.
  • The people who write them incorporate their biases, and algorithms often learn from human behavior, so they reflect the biases we hold.
  • Fairness, Accountability and Transparency in Machine Learning workshop, which considers the role that machines play in consequential decisions in areas like employment, health care and policing.

  • The tech world is notoriously resistant to regulation, but do you believe it might be necessary to ensure fairness in algorithms? Yes, just as regulation currently plays a role in certain contexts, such as advertising jobs and extending credit.
  • Should computer science education include lessons on how to be aware of these issues and the various approaches to addressing them? Absolutely!

Silicon Valley's Youth Problem - The New York Times - 0 views

  • There are more platforms, more websites, more pat solutions to serious problems — here’s an app that can fix drug addiction! promote fiscal responsibility! advance childhood literacy!
  • The doors to start-up-dom have been thrown wide open. At Harvard, enrollment in the introductory computer-science course, CS50, has soared. Last semester, 39 percent of the students in the class were women, and 73 percent had never coded before.
  • I protested: “What about Facebook?” He looked at me, and I thought about it. No doubt, Facebook has changed the world. Facebook has made it easier to communicate, participate, pontificate, track down new contacts and vet romantic prospects. But in other moments, it has also made me nauseatingly jealous of my friends, even as I’m aware of its unreality. Everything on Facebook, like an Instagram photo, is experienced through a soft-glow filter. And for all the noise, the pinging notifications and flashing lights, you never really feel productive on Facebook.

  • Amazon Web Services (A.W.S.)
  • “But now, every start-up is A.W.S. only, so there are no servers to kick, no fabs to be near. You can work anywhere. The idea that all you need is your laptop and Wi-Fi, and you can be doing anything — that’s an A.W.S.-driven invention.” This same freedom from a physical location or, for that matter, physical products has led to new work structures.
  • Despite its breathtaking arrogance, the question resonates; it articulates concerns about tech being, if not ageist, then at least increasingly youth-fetishizing. “People have always recruited on the basis of ‘Not your dad’s company,’ ” Biswas said.
  • On a certain level, the old-guard-new-guard divide is both natural and inevitable. Young people like to be among young people; they like to work on products (consumer brands) that their friends use and in environments where they feel acutely the side effects of growth. Lisa and Jim’s responses to the question “Would you work for an old-guard company?” are studiously diplomatic — “Absolutely,” they say — but the fact remains that they chose, from a buffet of job options, fledgling companies in San Francisco.
  • Cool exists at the ineffable confluence of smart people, big money and compelling product.
  • Older engineers form a smaller percentage of employees at top new-guard companies, not because they don’t have the skills, but because they simply don’t want to. “Let’s face it,” Karl said, “for a 50-something to show up at a start-up where the average age is 29, there is a basic cultural disconnect that’s going on. I know people, mostly those who have stayed on the technical side, who’ve popped back into an 11-person company. But there’s a hesitation there.”
  • Getting these job offers depends almost exclusively on the candidate’s performance in a series of technical interviews, where you are asked, in front of frowning hiring managers, to whip up correct and efficient code. Moreover, a majority of questions seem to be pulled from undergraduate algorithms and data-structures textbooks,
  • “People want the enterprise tools they use at work to look and feel like the web apps they use at home.”
  • Some of us will continue to make the web products that have generated such vast wealth and changed the way we think, interact, protest. But hopefully, others among us will go to work on tech’s infrastructure, bringing the spirit of the new guard into the old.

Group Projects: creating an environment for collaboration. Interview with Tom Ewing. - ... - 0 views

  • In the group that did the best someone took on a lead role and was able to delegate and make sure things were done effectively. This makes me wonder about teaching project management and group dynamics for the social sciences and other solo-author disciplines?

How Curiosity Leads to Creativity -- Science of Us - 0 views

  • We live in a culture that very much fetishizes passion and certainty. I think sometimes people lose their way in the creative path because they’re being told to follow their passion. It can be a really cruel piece of advice
  • Forget about the notion of passion, and give your attention to your curiosity. Passion burns hot and fast, which means it can come and go
  • I have followed things in my life that barely had a pulse, but it was the only thing that was there that day
  • ...2 more annotations...
  • But part of that path, of leading a creative life, is to believe that there’s a reason that you’re into this thing, whatever it is.
  • Every time I hear someone talk about discipline all I see is the scratch marks on the walls they left with their fingernails. All that anxiety. You’ve got to take it easy on yourself. You’re doing an inherently weird thing. You’re investing time and money into making something that nobody asked you to do. It’s inherently a wacky thing to do. You’re going to have strange feelings, especially about the uselessness of it all. But then you think, I’m going to stay with it, because it’s more interesting than anything else.

7 EFFECTIVE WAYS TO BUILD WILLPOWER - Project Man Beyond - 0 views

  • Remember those moments when you just don’t feel like doing a task, but you know you have to?
  • Starting is actually the secret to accomplishing a lot of things. Just by starting, somehow you are compelled to continue on. 
  • As psychologist Roy Baumeister and science writer John Tierney pointed out in their Willpower book, it works a lot like a muscle. Like a muscle, it can get tired and need recovery.

  • It also needs to be nourished. It is affected by a lot of factors such as stress, physical health, and nutrition. In other words, your “spirit can be willing but the flesh is spongy and bruised.”
  • 1.) DEFINING WHAT MOTIVATES YOU
  • f there is no underlying passion and serious motivation behind a goal, temptations can easily power their way against you.
  • .) DIVIDING YOUR GOALS INTO SMALLER PIECES
  • Contrary to many Vince Lombardi-type motivations, willpower is more like an energy that can be depleted. Willpower is a finite resource. It works in cycles; it is something that you build on and know when to maximize.
  • 3.) GRADUAL PROGRESSION & ACCUMULATING POSITIVE REINFORCEMENT
  • 4.) YOUR HEALTH MATTERS
  • 5.) WORK ON YOUR EMOTIONAL BLOCKAGES
  • Find that breakthrough and learn why, at times, you may feel like it doesn’t matter.
  • 6.) ACKNOWLEDGING YOUR LIMITATIONS
  • 7.) MEDITATION

Habits: How They Form And How To Break Them : NPR - 0 views

  • His new book The Power of Habit explores the science behind why we do what we do — and how companies are now working to use our habit formations to sell and market products to us.
  • every habit starts with a psychological pattern called a "habit loop," which is a three-part process. First, there's a cue, or trigger,
  • third step, he says, is the reward: something that your brain likes that helps it remember the "habit loop" in the future.

"As soon as they did that, people started using it at the end of their cleaning habits to make things smell as nice as they looked," he says. "And what they figured out is that people crave a nice smell when everything looks pretty. Now, no consumer would have said that. ... But companies can figure this out, and that's how they can make products work."

Lectures Aren't Just Boring, They're Ineffective, Too, Study Finds | Science/AAAS | News - 0 views

  • Although there is no single definition of active learning approaches, they include asking students to answer questions by using handheld clickers, calling on individuals or groups randomly, or having students clarify concepts to each other and reach a consensus on an issue.
  • But I don’t think there should be a monolithic stance about lecture or no lecture. There are still times when lectures will be needed, but the traditional mode of stand-and-deliver is being demonstrated as less effective at promoting student learning and preparing future teachers.”

Hot-desking a hot-button issue but it's not going away - 0 views

  • Hot-desking, as I'm sure you know, is the practice of not assigning desks to staff but requiring them to find a new workspace each day.
  • Hot-desking is often accompanied by "activity-based working", where staff are issued laptops or other technology and given the flexibility to work wherever and whenever.
  • Problems included increased distrust, distractions, uncooperative behaviour and negative relationships.
  • ...3 more annotations...
  • Research published in academic journal Applied Economics earlier this year included a survey of 1000 Australian employees. It found as work environments become more shared, workers report increased demands and decreased supervisor support. Workplace friendships are not improved as a result.
  • The research suggests the practice of movement creates additional work and a sense of marginalisation for hot-deskers.
  • For me the most fascinating insight was the finding that a social structure emerges distinguishing employees who settle in one place and become quasi-owners of a desk, and others who have to move constantly. That's certainly true from my experience.
