Funny to think that a bit over a decade ago, I poo-pooh'd the idea of a camera on a cell phone, "because my compact digital camera takes so much better pictures".

Not bad little Pixel, not bad. (And Colorado, you've got good taste in your state flower -- the Blue Columbine is gorgeous.)

As always, +Emin Gün Sirer 's posts about crypto are fascinating from the technical and social/economic glimpse they give into the ecosystem.

And the responses to his post are a marvelous illustration of Upton Sinclair's quip... "It is difficult to get a man to understand something, when his salary depends on his not understanding it."
We had the biggest crowd-funding event in history last week, when Bancor raised $144M for a scheme to manage reserves for coins, a central bank of sorts for cryptocurrencies. This post describes why the Bancor approach is flawed. #Ethereum

I think Google's music-recommendation AI has developed a sense of humor. I'd been listening to 80's German synthpop band "Propaganda", and it created a radio station "For Fans of Propaganda." The first few times I listened to it it was exactly what I expected - more mid-80s euro synth pop happiness.

And then.. then it started playing entirely Russian techno pop. Perhaps it's learned the other meaning of Propaganda.

They are catchy, though. Reminds me of Aqua. Yes, yes, my taste in music is simply that bad. No, it wasn't I who was listening to the Frozen soundtrack - the danger of having one's account linked to Google Home. :-)

A discussion thread between +Daniel Lemire and Maxime Chevalier reminded me of one of the optimization tricks I used when I was playing with cryptocurrencies a while ago.

Trying to achieve Wok hay without a wok. (We're at a rental for the week). A superheated cast iron pan seems to do the trick surprisingly well.

The follow on to my earlier post about finances for Ph.D. students; this time, for just-starting or about-to-start faculty.

Thinking back about our almost two years with an Amazon Echo and now a Google Home. An experiment I don't regret in the slightest.

Ahh. United never fails to deliver their failure to deliver my family for our holiday travel. On the bright side, the weather in Pittsburgh is good today, so I'm cautiously optimistic that we'll actually make it out of here today.
