Any recommendations for backing up (private) keys? Like pgp keys for example? I consider printing them on paper, as text or QR code. Anything better than that?

AFAIK, quite some components (Hadoop, Kafka, Spark, etc) of a typical big data stack are JVM based. Scala is JVM. And quite some people hate Java. That could be an answer.

For people with just some basic computer graphics background that don't know what this "deferred rendering" is: when this technique became popular, these [1] slides were popular and inspired many.

xwintermutex | 10 years ago | on: What 50,000 watts of RF energy sounds like through a jumper cable
I guess it is because of the use of amplitude modulation [1], where the envelope ("strength") of the carrier (that is some higher frequency signal) follows the signal that is modulated onto it (speech, in this video). With say FM it wouldn't work, I presume.

I think that learning of (and avoiding) the Granny Knot [1] is the best I ever learned about shoelace knots. If your shoelaces occasionally get loose while walking, check it.

If you have a few pins that you suspect to be JTAG, but don't know which is which, there are tools for that too [1], (instead of manually trying).

> As the linked article mentions, the solution was to optimize a massively-parallel algorithm by finding coherent rays that can be efficiently calculated together. It's a batch method: start casting a bunch of rays, identify similar rays and group them, calculate collisions for each group, cast reflected rays, identify similar rays and group them, etc. What I like about it conceptually is that in a way it treats light as a field rather than as individual directed rays.
How does this differ from "coherent ray tracing" and "ray packets", like people have been doing the last 15 years?
(e.g. "Interactive Rendering with Coherent Ray-Tracing" by Wald et al.: http://www.sci.utah.edu/~wald/Publications/2001/CRT/CRT.pdf)

Trivia: a Johnny Popper is a John Deere model M. I am currently in the process of restoring one. It is called a popper because of its distinct sound, caused by the non-180 degree angle between the two cylinders on the camshaft. I dream about every day to become a farmer.
