makeself is a small shell script that generates a self-extractable compressed TAR archive from a directory. The resulting file appears as a shell script, and can be launched as is. The archive will then uncompress itself to a temporary directory and an arbitrary command will be executed (for example, an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world.
/etc/net represents a new approach to Linux network configuration tasks. Inspired by the limitations of traditional network configuration subsystems, /etc/net provides built-in support for configuration profiles, interface name management, removable devices, full iproute2 command set, interface dependencies resolution, QoS, and firewall configuration frameworks. /etc/net provides support for the following interface types: ethernet, WiFi (WEP), IPv4/IPv6 tunnels, PSK IPSec tunnels, VLAN, PLIP, ethernet bonding and bridging, traffic equalizer, Pent@NET, Pent@VALUE, SkyStar-2, TUN/TAP, OpenVPN TUN/TAP, usbnet, and PPP. Due to its modular structure, support for new interface types can be added without overall design changes.
DIY Zoning is a set of tools and instructions for controlling a state-of-the-art HVAC (Heating, Ventilation, and Air Conditioning) system. It covers airflow balancing, temperature control and zoning, energy conservation measures, remote access, 1-wire devices, and home automation.
Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
Z1 SecureMail Gateway is a central, server-based software solution that provides encryption and digital signatures (PGP and S/MIME) for the entire email traffic of an organization. It works with organizational certificates and certificates for individual users, groups, or organizational units. It provides its services transparently to end users. Z1 SecureMail Gateway automatically finds certificates of external users or companies via Internet. Secure email traffic to customers, suppliers, and partners is easily established. Evaluation packages for Debian and Solaris are available for download.
SLOCCount is a suite of programs for counting physical source lines of code (SLOC) in possibly large software systems. It can count physical SLOC for a wide number of languages. It can take a large set of files and automatically categorize their types using a number of different heuristics, and also comes with analysis tools.
lesspipe.sh is an input filter for the pager less as described in less's man page. The script runs under a ksh-compatible shell (e.g. bash, zsh) and allows you to use less to view files with binary content, compressed files, archives, and files contained in archives. Viewing files by accessing a device file is implemented to some extent. It supports many formats (both as plain and compressed files using gzip, bzip2, and other pack programs). Syntax highlighting of source code is possible through an included script, "code2color", or an external program (pygmentize).
PDFjam is a small collection of shell scripts that provide a simple interface to some of the functionality of the pdfpages package for pdfLaTeX. Facilities include n-up imposition, page rotation, reflection and trimming, selection of pages, and many more. PDFjam depends on a working installation of (pdf)LaTeX, complete with the pdfpages package. For Mac OS X, some example applications (droplets) are provided for drag-and-drop access.
OraRep is a PL/SQL snippet (embedded in a shell script) which creates a well-formatted HTML report on a given database instance, providing you with an overview on your instance(s), some hints for performance tuning, and more. It has been tested with Oracle 8.1.7, 9.0.1, and 9.2. The script easily fits into a cron task to be run on a regular basis. Sample output (HTML) is included. OSPRep does the same job for Oracle StatsPack Reports based on SnapShot Levels up to 7, and provides additional "plugins" for more detailed reporting on special issues. It also optionally creates a separate page with charts to visualize the results and more.
