BlogMax makes it easy to use Emacs to maintain a Web log. You define templates and an FTP site for uploads. Most of your site's content is defined by text files. Saving a text file automatically wraps the template around it, expands macros and shortcuts, and saves the HTML file. Other commands in "weblog" mode upload files via FTP, create an RSS file, yank links or blockquotes into the buffer, create shortcuts, etc. The BlogMax Web site was, of course, created with BlogMax. It has been tested in Emacs 20.3.1 on Windows and Emacs 20.4.1 on Mandrake Linux.

ECB is a source code browser for (x)emacs. It displays a couple of windows that can be used to browse directories, files, and file contents like methods and variables. It supports source code parsing for languages like Java, C, C++, Elisp, Scheme, Perl, TeX, LaTeX, etc. In addition, it offers an (optional) permanent "compile window" at the bottom of the emacs frame, which is used to display all help and compile output. The rest of the frame is called the "edit area", which can be divided into several edit windows that are used for editing the sources. Deleting some of the edit windows neither destroys the compile window nor the browsing windows. It requires the CEDET suite.
Funky is an embeddable functional programming language. It is stable, fast, and small. It includes all four dialects in a single DLL, which without optimization isless than 140 K. It can be embedded into an existing C++ application in minutes. The syntax is heavily borrowed from Lisp, because of its simplicity.
