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.

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)

"Facebook changed the profile to her real name against her will ..."

How did they know her real name?

I agree with his problems with status codes.

What about Java?

What excited me most in that article is the line "The press event also saw Sony announce that long-awaited game The Last Guardian would soon be released."

FYI, Ken Silverman [1] is involved in this project.

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.

Looks more like C than idiomatic C++ at a first glance.

In the Netherlands, the public transport card "ov-chipkaart" used Mifare classic too [0]. Even worse, the "defensiepas", for access to military bases, uses it too [1], even as of today.

But wait... how can the pharma industry profit from this?

And if you potentially enjoy fiction featuring Turing, read Cryptonomicon: http://en.wikipedia.org/wiki/Cryptonomicon

A bit of context: these models are used in countless of computer graphics publications. Try a image search for "Stanford Bunny" for example.

Now we only need batteries that don't self-discharge within decades.

Up to 8K displays? Other than those Bloomberg terminal guys, who needs more than 3 displays?

Too bad that there aren't many details on the wireless link (e.g. frequency, protocol)

Are those images CGI or real?

I see, thanks!

I don't understand this sentence: "One caveat to the randomness is that in order to preserve chronological ordering if a client creates multiple push IDs in the same millisecond, we just ‘increment’ the random bits by one."

Nice work. As someone who built physics engines years ago, it makes me kind of happy that solving stacking is still no trivial task.

The LiDAR part is neat. Anyone knows if Google uses this too for mapping?

Geeky concepts illustrated using squirrels and nuts, what else does one need?

Reminds me of a Dutch startup that is doing about the same: http://nerdalize.com/

One can prepend any data to a zip file and it will still be valid.

Now it would be a nice next step if he uses his wifi card's RSSI + Helmholtz reciprocity to verify the theory.
