How to hallucinate with ping-pong balls and a radio

DO YOU EVER want to change the way you see the world? Wouldn't it be fun to hallucinate on
your lunch break? Although we typically associate such phenomena with powerful drugs
like LSD or mescaline, it's easy to fling open the doors of perception without them: All it
takes is a basic understanding of how the mind works.

The first thing to know is that the mind isn't a mirror, or even a passive observer of
reality. Much of what we think of as being out there actually comes from in here, and is a
byproduct of how the brain processes sensation. In recent years scientists have come up
with a number of simple tricks that expose the artifice of our senses, so that we end up perceiving
what we know isn't real - tweaking the cortex to produce something uncannily like
hallucinations. Perhaps we hear the voice of someone who is no longer alive, or feel as if our
nose is suddenly 3 feet long.

Remote debugging for ARM target board

By
Remote debugging for ARM target board With GDB one can both trace and modify code and data flow, and otherwise analyze the behavior of code, without explicitly changing any of it. Rather than run a full-blown instance of GDB on the target platform, you can use GDBserver , a program that lets you run GDB on a different machine than the one on which your program is running. The advantage of using GDBserver is that it needs just a fraction of the target resources that GDB consumes, because it implements only the low-level functionality of the debugger -- namely setting breakpoints and accessing the target processor registers and read/write application memory. GDBserver takes control of the application being debugged, and then waits for instructions from a remote instance of GDB running on a development workstation. Remote target needs to have debugging stub (gdbserver), The gdbserver is also referred to as the 'stub' and must be cross-compiled for that targ...
