SVL (System Call Virtualisation Layer) is a C++ library that can be used to detect, abort, and rewrite system calls. The possible uses include, but are not limited to, studying the system call trace of a program; sandboxing a program to tighten security; or selectively rerouting system calls, such as file operations, to different paths or even different sytems to create distributed architectures. SVL allows you to change the low level constructs for system call invocation by allowing you access to both the registers and the target program's memory. As well as having the low level access, SVL has high level classes for dealing with the major syscall operation types.
new-words is a script that helps you to control your vocabulary and find unknown words in texts before you start to read them. It is intended to be run in a console; the interactive part of the work is done by means of a text editor (vim by default). It features: words frequency information about words in a text; users vocabulary control; support for several languages; dictionary software integration; and the ability to make notes for unknown words.
