Objective-C Coding Convention and Best Practices

Most of these guidelines are to match Apple's documentation and community-accepted best practices. Some are derived some personal preference. This document aims to set a standard way of doing things so everyone can do things the same way. If there is something you are not particularly fond of, it is encouraged to do it anyway to be consistent with everyone else.

This document is mainly targeted toward iOS development, but definitely applies to Mac as well.

Operators

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Rust developer tools - status and strategy

Availability and quality of developer tools are an important factor in the success of a programming language. C/C++ has remained dominant in the systems space in part because of the huge number of tools tailored to these lanaguages. Succesful modern languages have had excellent tool support (Java in particular, Scala, Javascript, etc.). Finally, LLVM has been successful in part because it is much easier to extend than GCC. So far, Rust has done pretty well with developer tools, we have a compiler which produces good quality code in reasonable time, good support for debug symbols which lets us leverage C++/lanaguge agnostic tools such as debuggers, profilers, etc., there are also syntax highlighting, cross-reference, code completion, and documentation tools.

In this document I want to layout what Rust tools exist and where to find them, highlight opportunities for tool developement in the short and long term, and start a discussion about where to focus our time an

Interface Versioning (InterVer)

Never break backcompat, keep the API nimble

An extension of SemVer with a stricter (yet more realistic) backcompat guarantee, that provides more flexibility to change the API, for libraries that are packaged and downloaded (not services accessed remotely over the Internet (see Note 4)).
