[05:21:12] A BeagleBoard is "bricked" when it no longer boots in its routine way. Nathanm placed a link to a page that explains how to recover ("unbrick") a broken BeagleBoard. This is a great advantage of the BeagleBoard, since most closed systems and some open systems cannot be easily recovered once they are "bricked". [06:32:06] Joint Test Action Group (JTAG) was originally designed for printed circuit boards, though it is now primarily used for accessing sub-blocks of integrated circuits and debugging embedded systems. The JTAG interface also allows device programmer hardware to transfer data into internal non-volatile device memory.

[09:58:16] "memcpy" is one of many C functions. [10:02:06] xv is a shareware program responsible for displaying and modifying digital images under the X Window System. xv can be run from either a command line or a graphical interface. [11:52:04] wxPython (a free software) is a cross-platform wrapper for the Python programming language.

[12:11:39] GNU Radio, now an official GNU project, is a free software toolkit for learning about, building, and deploying software-defined radio systems. The GNU radio is a signal processing package intended to give ordinary software people the ability to utilize the electromagnetic spectrum. [12:53:13] The Universal Software Radio Peripheral (USRP) is a high-speed USB-based board used to make software radios. It is intended to be a relatively inexpensive hardware device with an open design and free software to be integrated with the GNU Radio. It's design provides the flexibility for developers to make their own daughterboards for specific needs.
