Re:Ask HN: How do you manage your SSH keys? on Sunday March 13, 2016 @05:21AM (#11276954)
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?
Re:Scala School on Friday March 11, 2016 @03:59AM (#11265518)
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.
Re:Modern textureless deferred rendering techniques on Friday March 04, 2016 @07:52AM (#11223409)
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.

[1]: http://www.slideshare.net/guerrillagames/deferred-rendering-...

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.

Re:Shoelace knots on Friday September 11, 2015 @02:21AM (#10202268)
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.

Re:Reverse Engineering PCBs with JTAG on Wednesday August 05, 2015 @03:12PM (#10012124)
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).

Re:Disney's Hyperion Renderer on Monday August 03, 2015 @09:42AM (#9995687)
> 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)

How did they know her real name?

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.

Re:Death of a Programmer, Life of a Farmer on Tuesday May 05, 2015 @04:44PM (#9494853)
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.
Re:How to Crack Mifare Classic Cards on Wednesday April 22, 2015 @02:28AM (#9418897)
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.

Re:The Stanford 3D Scanning Repository on Thursday April 09, 2015 @06:23AM (#9346647)
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?

Are those images CGI or real?

Re:2^120 Ways to Ensure Unique Identifiers on Thursday February 12, 2015 @04:23AM (#9038067)
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."
Re:Matter.js – A 2D rigid body physics engine for the web on Tuesday January 20, 2015 @04:01AM (#8916031)
Nice work. As someone who built physics engines years ago, it makes me kind of happy that solving stacking is still no trivial task.
