Genymotion includes its own copy of adb, which interferes with the one bundled in the Android SDK.
The easiest way to fix seems to be to update your Genymotion Settings so it uses the same ADB as your Android SDK:
Just check the "Use custom Android SDK tools" option and enter your desire...
How does one get started with procedural generation?
...t for the mathematically squeamish, but that is how procedural content is done.
Shadertoy was created by a procedural genius, Inigo Quilez, a product of the demo scene who works at Pixar. He has some youtube videos (great example) of live coding sessions and I can also recommend these.

Why are variables “i” and “j” used for counters?
...s, like if you have a bunch of variables x1, x2, ... xn, then an arbitrary one will be known as xi.

What is also apparent is that the body of the route do...
What does “atomic” mean in programming?
...5465498L;
Indeed, the variable is written using two separate operations: one that writes the first 32 bits, and a second one which writes the last 32 bits. That means that another thread might read the value of foo, and see the intermediate state.
Making the operation atomic consists in using sy...
Accessing an array out of bounds gives no error, why?

In general, whenever you encounter undefined behavior, anything might happen. The application may crash, it may freeze, it may eject your CD-ROM drive or make demons come out of your nose. It may format your har...
