Attention Sniffing Events

I get disproportionally upset with websites playing videos which pause when you background their browser tab. I don’t understand why browsers respect the focus and blur event at the window level, clearly they only benefit nefarious purposes seeking to milk a poor soul. Either by forcing them to watch content, or by building a better model of their attention behavior. Attention which we all know is a currency to be extracted on the internet.

A while back I added a Tampermonkey script to catch the registration of these events, and invalidate it. Out of curiosity, I added reporting to it these past 10 days. I was curious to know how prevalent the practice was.

Out of 140 domains visited these past 10 days, 28 cared to know whether my eyeballs were pointed at them or not. 8 were in the constellation of Google.

Now of course, I don’t use social media, I have pretty established work routines, and 2 layers of ad blocking. I suspect both the numbers of domains visited, and the number domains interested in my eyeballs would be significantly higher if I disabled ad blocking. But do I really want to subject myself to 10 days of ads? No, I really don’t, not even for science.

SketchyBot 1.0

I finally built a standard sized one. I ran into a few unexpected challenges given how smooth the small one went.

It really isn’t the most accurate machine, the belts inside aren’t timed, but it does pretty ok with some rendering algorithm and is fun.

X,Y Coordinates Redux

As is now tradition, I taught my session on X,Y coordinates to local 5th graders.

As before, the collaborative drawing website I made worked wonder for getting them to time-share on the drawing machines. Each of them picks a square and works on it, I disable actual drawing for the class and they can only “code” with go_to(x,y) type commands. When they submit their drawing, the machines get to work. Kids absolutely love the idea of controlling the machines, and having that bit of time to shine as their drawing is being rendered. They are all extremely motivated to figure out the minutia of the code to these effects.

It looks like I bring a new machine every other year, we started with the tabletop plotter, then I added the gondola one, and of course this year it was lasers!

The kids really loved it as I suspected they would. I have learned that light management is a bit of an issue in the classroom when it needs to be dark but not too dark. Something to improve for next year.

It was a good crowd this year and I’ve been tempted to see if I could do something extra having some of them build the etch-a-sketch plotter.
