Xidel is a command line tool to download Web pages and extract data from them. It can download files over HTTP/S connections, follow redirections, links, or extracted values, and process local files. The data can be extracted using XPath 2.0, XQuery 1.0, and JSONiq expressions, CSS 3 selectors, and custom, pattern-matching templates that are like an annotated version of the processed page. The extracted values can then be exported as plain text/XML/HTML/JSON, or assigned to variables to be used in other extract expressions or be exported to the shell. There is also an online CGI service for testing.
Vocab Builder is a collection of two separate programs. The client is the testing application that uses a drill-style method of building your vocabulary in a foreign language, similar to using flash-cards. The editor allows you to create a new, or modify an existing, database for your own personal use. Since the design of the project allows a user to create their own databases/tests, they can not only focus on the words they want/need to learn, but also are not restricted by availability of choice. No more are you restricted by only the databases available to you. Many language teaching applications only allow you to learn the languages they've supplied you. Most North American-based programs cater to English speaking users and only give you a selection of other languages to choose from. Not only can Vocab Builder use any language combination of Native and Secondary languages but it's also open-ended. You can share your tests with others. You can expand the database of words in any direction you want. Word lists are meant to be broken down into categories like colors, sizes, numbers, etc.
CPC (Continuation Passing C) is a programming language designed for writing concurrent systems. The CPC programmer manipulates very lightweight threads, choosing whether they should be cooperatively or preemptively scheduled at any given point; the CPC program is then processed by the CPC translator, which produces highly efficient event-loop code. This approach gives the best both worlds: the relative convenience of programming with threads, and the low memory usage of event-loop code. The semantics of CPC is defined as a source-to-source translation from CPC into plain C using a technique known as conversion into Continuation Passing Style. The current implementation of CPC has been used to write Hekate, a BitTorrent seeder designed to handle millions of simultaneous torrents and tens of thousands of simultaneously connected peers.
