Spinneret is a structured storage engine that can be thought of as an extended tuple storage system. It takes the best aspects of relational, object, and hierarchical databases and throws away the dead weight associated with those technologies. The benefit of Spinneret is that its data model is incredibly flexible, allowing it to expose its underlying data in any number of ways. It operates similar to an object database, but without hard ties to an originating language, and can also behave like a relational database without the burden of complex joins.
ProteomeCommons.org IO Framework is a proper Java framework for handling spectra and peak lists. The framework can read and write to a number of different spectra and peak list formats, and it provides a simple, intuitive Java object model for working with spectra or peak lists. All classes support two methods of handling peak list and spectrum data: in-memory or stream. The goal of this framework is to support all the popular MS and MSMS data formats, and to eliminate any time or effort involved in figuring out how to read and write peak list or spectrum files.
CTL is a cross-platform control dispatching tool that makes it easy to automate any kind of distributed systems management or application provisioning task. Rather than writing complex and error-prone scripts that over utilize "for loops", CTL handles the network dispatching for you and allows you to focus on the actual management tasks you need to accomplish. In addition to being a dispatching tool, CTL comes with pre-built cross-platform utilities so you don't have to script actions like file distribution or process and port checking. You can also write your own custom utilities and share them with others in your organization. Custom utilities are defined in XML, and your scripting can be done in multiple scripting languages (Perl, Python, etc.), *nix shell, Windows batch, and/or Ant.
ratproxy is a semi-automated, largely passive Web application security audit tool optimized for accurate and sensitive detection, and automatic annotation, of potential problems and security-relevant design patterns based on the observation of existing, user-initiated traffic in complex Web 2.0 environments.
Build systems fail to scale to large projects when rebuilding a small portion requires stat-ing every project file. Prebake is a build system that uses a long-lived service to hook into the file-system and watch for changes so it can avoid unnecessary I/O for incremental builds. It also solves common problems with Ant and Make: missing dependencies and build cruft from deleted source files. It does away with missing dependencies by doing away with explicit dependencies altogether. Build dependencies are inferred by intersecting globs; if one product takes *.c and produces *.o, and another takes *.o and produces *.lib, then the latter depends on the former. Prebake also gets the benefits of both a declarative build syntax (a la make) and the flexibility of hand coded shell scripts. It uses tightly sandboxed JavaScript and "mobile functions" to get the flexibility of a scripting language with the hard controls on side effects that allow for repeatable builds. In practice, the JS in build files looks declarative, like JSON, but the dynamism is there when you need it.
RepoGuard is an advanced validation framework with built-in integrations for several common version control systems. The integration is carried out by utilizing the hook mechanisms each version control system provides. The user may provide configurations that are processed through inversion of control mechanisms. RepoGuard is completely written in the Python programming language, which allows for easy integration of other tools. An extensible command line tool for advanced usage is provided, which allows for comfortable administration.
PirateWall is a simple Twitter Client. It displays search results for a certain keyword or hashtag in realtime in a shell-based environment. It can also be configured to act as a data provider for many different visualization tools. For example, it is possible to use the client as a text generator for many XScreensaver applications like "apple2" or "starwars". When used in a Unix shell environment, colorized output can be generated.
Weed-FS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files, and to serve the files fast! Instead of supporting full POSIX file system semantics, it implements only a key-file mapping. Instead of managing all file metadata in a central master, it manages file volumes in the central master and lets volume servers manage files and the metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers' memories, allowing faster file access with just one disk read operation. It is modelled on Facebook's Haystack design paper. Only 40 bytes of disk storage are required for each file's metadata, and disk reads are O(1).
