Thomas Joseph Kelly (June 14, 1929 – March 23, 2002) was an American aerospace engineer. Kelly primarily worked on the Apollo Lunar Module, which earned him the name of “Father of the Lunar Module” from NASA.

Kelly led the team at Grumman that designed and built the Lunar Module (LM2 shown)

Kelly graduated from Cornell University in 1951, where he was a member of the Quill and Daggersociety. Afterwards, Kelly obtained his MS degree from Columbia University and Ph.D. from the Polytechnic Institute of Brooklyn.

Kelly was the project engineer, engineering manager and deputy program manager for Grumman Aircraft‘s Apollo Lunar Module (1962–1970). His 2001 book Moon Lander: How We Developed the Apollo Lunar Module documents the process of designing, building and flying the Lunar Module.

WireGuard

Jovan Stosic May 10, 2021

WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs), and was designed with the goals of ease of use, high speed performance, and low attack surface. It aims for better performance and more power-saving than the IPsec and OpenVPN tunneling protocols. The WireGuard protocol passes traffic over UDP.

In March 2020, the Linux version of the software reached a stable production release and was incorporated into the Linux 5.6 kernel, and backported to earlier Linux kernels in some Linux distributions. The Linux kernel components are licensed under the GNU General Public License(GPL) version 2; other implementations are under GPLv2 or other free/open-source licenses.

#include – Arduino Reference

Jovan Stosic May 8, 2021

#include is used to include outside libraries in your sketch. This gives the programmer access to a large group of standard C libraries (groups of pre-made functions), and also libraries written especially for Arduino.

The main reference page for AVR C libraries (AVR is a reference to the Atmel chips on which the Arduino is based) is here.

Note that #include, similar to #define, has no semicolon terminator, and the compiler will yield cryptic error messages if you add one.

Syntax

#include <LibraryFile.h>
#include "LocalFile.h"
