JS Date Range Picker is a package to let the user pick a range between two dates. It can be used to present two form inputs that let the user choose dates using calendar pull down menus. The dates may be validated so the range end date is not set to a day before the range start date. The format of the dates and the week start day are configurable parameters. The chosen dates are returned in the ISO-8601 extended format.

PulkoCMS is a small and lightweight CMS. Instead of using a database for storing your pages, it relies on the standard Unix filesystem features. With fewer than 500 lines of code, it is easy to customize and alter for your own needs. It generates valid XHTML pages. It features a shoutbox, comments on all articles, categories (a 2-level system), hidden pages, easy customization of the appearance via CSS, and a simple photo gallery. It can send you notifications through XMPP/Jabber when someone posts a comment on your Website.
wadWiki is a extremely light and simple Wiki engine that anyone can modify. It aims to be a fast scratchpad for arranging ideas without frills and complications. Major releases are supported for more than three years, so server requirements don't get suddenly bumped. Since it is written using only procedural functions, anyone with basic programming skills can adapt it to new requirements. The extension API is stable. There is official hosting for third-party extensions. Because collecting knowledge is not the goal of this project, if you want a full-featured wiki engine, you may wish to choose another software like MediaWiki.
