15 Sorting Algorithms in 6 Minutes  Visualization and "audibilization" of 15 Sorting Algorithms in 6 Minutes.
Sorts random shuffles of integers, with both speed and the number of items adapted to each algorithm's complexity.
The algorithms are: selection sort, insertion sort, quick sort, merge sort, heap sort, radix sort (LSD), radix sort (MSD), std::sort (intro sort), std::stable_sort (adaptive merge sort), shell sort, bubble sort, cocktail shaker sort, gnome sort, bitonic sort and bogo sort (30 seconds of it). #developers #algorithm

July 4, 2014: "Fireworks Filmed with a Drone" | HD
Recorded by Jos Stiglingh: "No quadcopters injured during filming."
Location: West Palm Beach, Florida, USA. And no spectators injured!
Warning: Due to serious legal & safety issues, do not try this!
Read Forbes Article on risks and concerns:
Equipment: Jos flew through a fireworks show with a DJI Phantom 2 unmanned aerial system (UAS), popularly known as a recreational "drone" and filmed it with a GoPro Hero 3 digital camera.

Of course, all operators must use UAS vehicles responsibly and with proper training and guidance: "Be safe and show respect for others."
There are many important professional applications for UAS vehicles.

INDOCTRINATE is a really, really perfect word ...

“People always ask me, what is it? Why aren’t girls opting into computer science? What’s the issue? And so much of it is about culture. It’s the messages we’ve subtly and unconsciously sent to girls: that computer science and math is not for you. The video shows these little things that we do… that send these messages to these girls that this is not for you: don’t play, don’t get dirty. I think we teach girls at a very young age not to get dirty, to be nice, this whole princess myth. We indoctrinate our girls to behave in a certain way. And it translates to us as adults: we’re afraid of rejection, we don’t fail, we have to do the job before we apply for the job, we’re constantly worried about being liked"...
