Finding a use for Twitter

As part of the obligatory year-end reflections, I have noticed that despite consistent good intentions, I haven’t been posting here regularly this fall. As always, I hope to remedy that as I don’t imagine ever entirely abandoning Screenshot. However, in my absence from this space, I have been somewhat more active in another corner of the internet. After some false starts and a general sense of apathy about the service, I have found a use for Twitter that seems to be working for me, mostly as a replacement for Delicious which I found became cumbersome at some point a few years ago … Continue reading Finding a use for Twitter

Next, they rise up and kill us all….

My most recent weblog post was on teaching ethics to self-driving cars, flippantly titled At least they’re not using GTA as a data source. Except…. Self-Driving Cars Can Learn a Lot by Playing Grand Theft Auto Let’s console ourselves that “there’s little chance of a computer learning bad behavior by playing violent computer games” and instead admire the clever efficiency of allowing them to get practice navigating the complexities of realistic roads. And, in this case, it does seem that they are just extracting photo-realistic screenshots rather than having to produce authentic training data, which is a cool trick. But the fact that the … Continue reading Next, they rise up and kill us all….

At least they’re not using GTA as a data source

MIT’s Media Lab wants you to help crowd-source solutions to the Trolley Problem as a decision-making data set for self-driving cars. This is exciting news, because asking the internet to solve tricky moral dilemmas using binary decision making will surely reflect our societal values accurately. Putting aside snarky skepticism, I had the following thoughts as I went through a judging session: Having to pick one of these options without any “it depends” or “I don’t want to choose” selection got uncomfortable fast. After a few scenarios I started to question the definiteness of the outcomes. How is there equal certainty that plowing straight ahead through four … Continue reading At least they’re not using GTA as a data source

Exploring for information

There are a series of good quotes in this article about how librarians can get students to start understanding the scholarly frame for exploring information that highlight the general shape of the argument being made: That exploration is important in learning: “When small children observe and imitate, they are testing the physical world around them and coming up with their own understanding of how things work. Explicit instruction short-circuits that process.” That various pressures prevent students from seeing library research as exploration: “They are intensely curious about what the teacher wants, if not about the topic they’re researching, and often focus … Continue reading Exploring for information

Getting to Effective Ed-Tech

This Chronicle article discussing the Jefferson Education incubator at University of Virginia has been rolling around in my head the past couple of days as I’ve been part of a number of conversations about education, computing, and classroom technology. The problem Jefferson Education says they are setting out to solve is that the ed-tech industry is light on efficacy research for the technologies they are selling, and “”universally, everyone thinks it’s not their fault or not their problem” that the research isn’t a bigger part of the purchasing equation.” So their group will study “the political, financial, and structural barriers that keep companies … Continue reading Getting to Effective Ed-Tech

Prioritizing beyond deadlines

A friend shared this article about university students struggling to read entire books on Facebook, and while there are many thought provoking things here, one quote in particular struck me: “I would say that it is simply a case of needing to prioritise,” said Ms Francis, “do you finish a book that you probably won’t write your essay on, or do you complete the seminar work that’s due in for the next day? I know what I’d rather choose.” Reading that sentence, I had the dual reactions of “of course” and “the fact that that’s the decision is the problem”. … Continue reading Prioritizing beyond deadlines

Beautiful Lumino City

I try out many more games than I finish – even when they’re short – from a combination of lack of attention span and lack of skill. So it stands out to me when I finish a game of more than trivial length. This weekend I played through the end of Lumino City and I can say with confidence that I would have finished this one off even without a snowstorm keeping me inside. The major selling point of Lumino City, which of itself is enough to make it worthwhile, is the artwork. The scenes in the game are entirely … Continue reading Beautiful Lumino City

User Tracking Apps

There’s an interesting story out there about ads that play ultrasonic sounds that permit cross-device tracking. While this is being described as detecting devices that all belong to one user, it seems possible it would sometimes detect devices all belonging to the same family – a slightly different task but also one marketers are interested in solving. It likely depends on where and how frequently these linking ultrasonic sounds are emitted. And, as I’ve seen others note and is alluded to late in this article, the SilverPush software development kit that is largely being credited for current implementations of this technique … Continue reading User Tracking Apps

Advice for the Returning

It is the time of year that the media, newspapers, blogs and higher-ed focused venues put out articles on advice to college freshmen. I was thinking of adding to that collection, but it struck me that there’s an audience that could use some back-to-school advice as well but which seems to be largely ignored: sophomores. It’s an interesting omission, given that missteps, meandering, or general malaise is so common in the sophomore year that there’s an entire phrase for it: the “sophomore slump”. And yet while a Google News search on “freshman advice” returns a top-ten links filled with tips for students starting college (8 … Continue reading Advice for the Returning

Security/Learning Linkdump

I’ve accumulated a big collection of links this summer that are roughly related to security and/or machine learning and mostly connected to personal identification or human characteristics that I’m intending to share with my senior students when they return to campus in a few weeks. Having just noticed quite how large the collection has grown, it seems kind to pull them together into a semi-organized structure, as compared to my original plan of hitting send on an email filled with URLs, for their sake as well as my own. Taken together, it’s a nice little reading list. How your smartphone’s battery life … Continue reading Security/Learning Linkdump
