lwIP is a light-weight implementation of the TCP/IP protocol suite that was originally written by Adam Dunkels at the Computer and Networks Architectures (CNA) lab of the Swedish Institute of Computer Science but now is being actively developed by a team of developers distributed world-wide currently administered by Simon Goldschmidt and Dirk Ziegelmeier. The development homepage has the latest news and releases:

GNU Tool Kit GTK+Cross Platform Widget Toolkit for Creating GUIs in Linux
GNU / GIMP Tool Kit – Cross Platform – Maybe I do not need to use Qt.
GTK (formerly GIMP ToolKit[2] and GTK+[3]) is a free software cross-platform widget toolkit for creating graphical user interfaces (GUIs).[4] It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it. It is one of the most popular toolkits for the Wayland and X11 windowing systems.[5]

Are you a one percenter?
If you make more than 383,001 US dollars per year you are in the top 1% of income in the USA. Should you feel more guilty than someone making 40K$ per year? You are a 1 percenter! You may want to note if you make more than 32,000 dollars per year you are in the top 1 percent of world income. You are a 1 percenter!

Once upon a time in a galaxy called Ooc there lived a computer named R.J. Drofnats- or "R. J." as he preferred to be called-was happiest when hewas ate work typesetting beautiful documents.
Drofnats is Stanford backwards.

Notes
- Lines are 50 Ohms
- System was calibrated using the boards spliced together with brass shim. Was used as a through.
- Return loss was -30db or better from 0 to 1Ghz
