E is a programming language designed to make it easy to write distributed programs that are correct and secure. As a pure-Java library, ELib provides for inter-process capability-secure distributed programming. Its cryptographic capability protocol enables mutually suspicious Java processes to cooperate safely, and its event-loop concurrency and promise pipelining enable high performance deadlock free distributed pure-object computing. Objects written in the E language are only able to interact with other objects according to ELib’s semantics, enabling object granularity intra-process security, including the ability to safely run untrusted mobile code
HQ9+ was designed by Cliff L Biffle, who wanted a language where the canonical programs (Hello World, 99 Bottles Of Beer and a quine) were easy to write. The language has four instructions — H, Q, 9 and + — which may occur in either uppercase or lowercase, as shown in the example in the specification. The specification does not define the behaviour of unknown instructions, and this interpreter ignores unknown instructions.
