Asbru Web Content Management is an easy-to-use and inexpensive Web content management system. It runs on most major Web platform operating systems, databases, Web servers, and scripting languages. It is available in three editions: Personal (for individuals), Professional (for organizations), and Hosting (for Web hosting service providers).
CryptSharp provides a number of password crypt algorithms: BCrypt, MD5 (and Apache's htpasswd variant), PHPass (WordPress, phpBB, Drupal), SHA256, SHA512, and Traditional and Extended DES. It also includes Blowfish, SCrypt, and PBKDF2 for any HMAC (.NET's built-in PBKDF2 implementation supports only SHA-1). If you are looking to store passwords, odds are CryptSharp will have the algorithm you want.
The Dextop application framework allows you to create Rich Internet Applications based on .NET/Mono and Sencha Ext JS. It has proven to be useful for online business applications. It features a desktop-like Ext JS frontend, simplified client-server communication, a stateful programming model, real-time updates and notifications from the server, automatic column model generation, automatic store model generation, and automatic form generation.
ENet for C# wraps the C-language ENet networking library. For games and other realtime applications, if you use TCP, old data can hold up newer data, even if it is no longer relevant (old positions, etc.). Your players will perceive any lost packet as a "lag burst". ENet supports multiple in-order streams of data, and allows you to decide on reliability on a per-packet basis. The library is useful for both client-server and peer-to-peer architectures.
MBase is a .NET-oriented meta-programming framework. It is designed for rapid development and high quality implementation of custom programming language compilers, but can also serve as a robust and flexible embeddable scripting engine. Applications are not limited to .NET platform, since MBase can be used to implement compilers targeting other platforms - JVM, native assembly, C, etc.
MapServer is a CGI based Web mapping application development tool. It processes user defined configuration files and templates to allow for a wide variety of applications to be developed, including interactive mapping, and spatial query definition and processing. It supports several data formats. Key features include scale dependent map rendering, automatic scalebar and legend building, feature labeling with collision avoidance, logical and thematic classifications, and on-the-fly projection of raster and vector data. The application can also access other WMS servers as a cascading map server.
CVS, GIT, and Mercurial as well as other well-known version control systems cannot version directories. In other words, you cannot add empty directories. A "workaround" for this issue is to use placeholder files that are placed into empty directories. These placeholder files can then be committed into the repository and will make sure that, upon checkout, the directory tree is entirely reconstructed. The problem with using placeholder files is that you need to create them, and need to delete them if they are not necessary anymore (because sub-directories or real files were added). With big source trees, managing these placeholder files can be cumbersome and error prone. MarkEmptyDirs can manage the creation/deletion of such placeholder files automatically. It creates placeholder files in all empty "leaf" directories. If later on new files or directories are put into such directories, the placeholder files are not necessary anymore, and are removed automatically.
