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
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
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
I was catching up on some podcasts on a recent roadtrip and listened to an interesting two-part series on vehicle automation from 99% Invisible: Episode 170: Children of the Magenta which looks at the effect of fly-by-wire and airplane flight automation on flight safety and Episode 171: Johnnycab on automotive automation. Overall, the two episodes focus on the “automation paradox”, roughly the idea that as we automate more, we reduce our capability to deal with problems when automation fails. So, if automated cars become the norm, for the first stretch of time, essentially all drivers will still have experience driving … Continue reading Robots are great but where will I put all my stuff?
I got directed to a recent piece about tolerance for ambiguity as a job requirement and a skill education should help develop through this quote from a responding blog post: “To the extent that we can provide assignments and experiences in and among classes that give students the experience of getting a little lost and finding their way back, we may be able to build some of that tolerance for ambiguity in the kind of settings Selingo discusses.” While the original article focuses more on the idea of a “growth mind-set” and encouraging students to think of perseverance rather than … Continue reading Argument for Ambiguity
I was flipping through Spolsky’s Joel on Software today and, perhaps because I spent the morning working with our college-wide curriculum and some of our documentation of its outcomes, this passage jumped out at me: So why don’t people write specs? It’s not to save time, because it doesn’t, and I think most coders recognize this. […] I think it’s because so many people don’t like to write. Staring at a blank screen is horribly frustrating. Personally, I overcame my fear of writing by taking a class in college that required a 3-5 page essay once a week. Writing is … Continue reading Exercising my writing muscle
This quote from a recent Chronicle article Infantilized by Academe struck me, particularly with the chaos of the end of the academic year: Our students are often more distracted than we are, and so inured to distraction that they are unlikely to notice it. As other commentators have argued, the process of gaining admission to selective American colleges now requires presenting an array of accomplishments so vast and varied that any reflection that might accompany them is purely incidental. This thought resonates with recent conversations I’ve been having with students and colleagues about the amount that students try to take … Continue reading Leaving time for focus
This semester my intro programming students are doing a very scaled down model of how search-and-rescue robots might very stupidly explore a space while trying to keep themselves from clumping up with each other. It’s a first programming course for most of them, so have I mentioned that these simulated robots are very stupid. However, since I’ve been playing around with their project, I seem to be seeing interesting content about search and rescue robots cropping up all over the place: Last week (on April 23rd), there was a great NASA JPL livestream of a talk on Rescue Robots focusing … Continue reading Rescue Robots in the News
The snow situation isn’t as bad here in Western PA as it is on much of the east coast, but while waiting for things to lighten up enough for me to go out and shovel, I’ve been playing around with Pittsburgh’s new snow plow tracker. The system itself is only live while snow is falling – access it through the button on the right. I like the use of the “multiple vehicle” icon to keep things legible when zoomed out. It took me a bit of playing around to realize that if you adjust the “history display” slider at the … Continue reading Where’s my plow?
I am a crazy fan of advent calendars. In addition to my physical calendar of ornaments, I’ve got a collection of online calendars I’m “opening” each day as well. Here are my favorites I found this year: Saveur Cookie Advent Calendar: A new cookie recipe each day – check out day six’s Alfajores Erik Svedäng’s Advent Calendar: Fun little widgets to watch and, in some cases, interact with Advent of Indies: Each day another indie game is promoted alongside a freebie to enjoy (some available only on the day the door opens) LEGO Star Wars Game Advent Calendar: play through … Continue reading Counting down
