HD44780 (or compatible) LCD driver in C for Parallax Propeller, hacked together from PropWare's implementation
View HD77480-parallax-propeller.c
// WHY THIS MONSTROSITY EXISTS:
// PropWare has an excellent HD44780 LCD driver written in C++.
// I wanted something that was simpler, without the dependencies, and in C.
// So I took the basic implementation from PropWare and threw this
// together. I removed 8-bit support (4-bit mode is usually all you need) and
// it assumes 16x2 (although that is easy to change - see HD44780_init()).
// This is actually 3 files, you can see the big separator below.
// First is the header, then the library C code, then a demo program.
// You can just copy and paste what you need right
// into SimpleIDE or other Propeller C build setup and it will

Example of supporting additional elliptic curves for ECDSA to sign and verify with different key sizes. (Example uses curves with bit sizes smaller than P224 to achieve shorter signatures. Signatures are compatible with standard stuff like OpenSSL.)

Use ident to get username of incoming connection
View webserver-ident-username.go
// Example in Go of using the ident protocol to extract the username of the connecting user.
// The idea is to use this on corporate networks to identify users logged in to a Windows
// RDP machine by their ActiveDirectory username.
// NOTE: For Windows, this is a good ident server https://sourceforge.net/projects/retinascan/
// that supports multiple users and all that good stuff.
