"Parser combinators are an idea that I enjoy every time I go back and look at again. They are an approach to building parsers by composing very simple atomic parsers into bigger and bigger units which can ultimately express real world grammars. This idea has been particularly popular in functional languages where the parsers can naturally be thought of as functions from input strings to parse trees, and composition of parsers is just function composition. This approach often leads to a simple syntax which makes the resulting parsers pleasantly declarative in that internal-DSL kind of way. "

" The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. "

"In an earlier blog post, Creating or modifying Entity Framework EDMX files from code: an introduction to HuagatiEDMXTools.dll, I wrote about the EDMX file wrapper that is used by the Huagati DBML/EDMX Tools add-in for parsing, updating, creating, and writing EDMX files. HuagatiEDMXTools adds an easy to use object model on top of EDMX files (see documentation at http://huagati.com/edmxtools/help ), making it a lot easier to create/read/update EDMX files, and to write LINQ queries against Entity Framework 4 metadata. It also has a number of built-in queries and lookup functions that make it a breeze to work with Entity Framework 4 EDMX files from code."
