Alignment and scale drift is usually solved via loop closure. Clearer example in the LSD-SLAM: https://www.youtube.com/watch?v=GnuQzP3gty4&feature=youtu.be... . By the way it seems like the researcher behind DSO and LSD-

If you're at 10k req/sec while processing nothing you can't possibly achieve a higher rate on real workloads. It establishes a hard cap on the best case scenario for a node server that manages to parallelize all IO work. I am

For this application where he was getting "hundreds of requests per second" at 500M users, if he suddenly grew another 10x he would've had to start scaling horizontally instead of running on just one machine.

In case it wasn't clear, I am saying 10k req/sec is low... (compared to go/java which is 5 times as fast)

Both nodejs and flask can barely hit 10k requests per second even if it doesn't touch database: https://medium.com/@tschundeee/express-vs-flask-vs-go-acc087...

Some jsfiddle or codepen examples would make this much more readable. Kind of tedious to inspect source to pick out the relevant bits for each approach to compare. But I guess this article was written for people who are already deeply famil

Just wondering, is there still any legitimate reason for doing this over using something like svg? Or is it mostly to show off in the same spirit as obfuscated C contests or demo scenes?

Why aren't these data structures also good for main memory? Is the gap between L1/L2 cache vs main memory not large enough? (1ns vs 100ns)

If someone did this in the US, can they get in trouble? When exactly does "hacking" a game become illegal? What about people doing it for research like the machine learning mario guy: https://www.youtube.com/watch?

I didn't follow that piece of news closely but I thought it was just native support to make products like Oculus's GearVR more usable but you will still need something like gear vr to make it work?

I think it's a smart move. Every major tech company is investing heavily into VR/AR to hedge their bets. Examples: Facebook with Oculus(acquired for $2B) Google with Glasses, Cardboard, MagicLeap($542 million in series B)

The hololens can already last 5.5 hours so it doesn't seem that impossible of a problem: https://www.youtube.com/watch?v=3AADEqLIALk . The dealbreaker right now seems to be resolution and a narrow field of view where it

Ah I didn't know. I usually have no trouble loading simple models from blender on clara.io so I assumed it will just work with more complex scenes.

You can probably show off your model to world with little effort using three.js. If you can export it as obj/mtl then you can probably just adapt this code: http://threejs.org/examples/#webgl_loader_obj_mtl

This problem is also on stackoverflow: http://stackoverflow.com/a/1391001 . It solved it by wrapping with a superclass that you downcast from. You won't be able to work with them by value due to object slicing but

What's the equivalent pattern in C++ to do this then? Specifically a contiguously allocated but variable length struct. I was thinking you can use template: template <int N> struct ion_system_heap { struct ion_h

For the "thinking a panda is a vulture" problem, don't humans fail in similar ways? The analogous examples for us are camouflage, optical illusions, logical fallacies, etc. It doesn't really have to be perfect as long as
