deawk is a very simple double-entry bookkeeping system designed for self-employed people. It uses three (text) data files: transactions, a chart of accounts, and an optional vehicle log. Reports are generated by running bash scripts which run awk. deawk currently does not support depreciation of capital assets.
pwgrep is a simple password manager that manages a database file using encryption of GnuPG. It uses encryption and version control on all of the passwords that are stored. The password database can be used on several hosts at once with automatic synchronization. Even several users can share the same password database. The versioning system will keep track of who was changing which entries and at which time. The versioning system to use can be configured (and is Subversion by default). Besides passwords, pwgrep can also be used for storing a collection of files like certificates. The file shredding command for secure deleting of temporary files can be configured. A local backup of all database changes is automatically made. It can be used without a GUI (such as through an SSH session).
Newfangle is a literate programming technique for LyX (or LaTeX) inspired by notangle. It comes in two parts. The weave part that produces the formatted document is implemented entirely in LaTeX, and the tangle that generates the source code is implemented in awk for portability. Naturally, newfangle is written using literate programming techniques, using itself, and so the source is also the documentation. The source is written using the LyX document editor, an excellent front end to LaTeX. LyX is not required, but newfangle provides formatting support for LyX. Literate programming makes you write good code, because if you can't write a good justification or explanation for your code, it makes you think again and write something that you can explain.
snmp2xml is a program to convert snmpget output to XML. The output from snmpget, snmpwalk, or snmpbulkwalk is first filtered to correct for SNMP agent flaws and then processed into XML. This XML can be passed through xmllint to tidy it up or it can be processed by an XQuery or XSLT processor. The XML output represents all the SNMP data such that the original SNMP output can be reproduced if desired with an XSLT stylesheet (which is included). The snmp2xml converter has been tested on 7 SNMP agents: Mac OS X, Apple Time Capsule, the Billion ADSL router, the Huawei S9306 switch, the Foundry/Brocade CES and MLX-4 switches, and the Nortel 425 switch.
UnifiedSessionsManager is a unified and simplified interface for the use and management of local and remote sessions on physical and virtual machines. It provides management of distributed and stacked virtual machines, management of desktops and workspaces on multiple monitors, seamless access to all types of sessions, and support of encrypted connections using SSH.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
MrTools is a suite of tools for managing large, distributed environments. It can be used to execute scripts on multiple remote hosts without prior installation, copy of a file or directory to multiple hosts as efficiently as possible in a relatively secure way, and collect a copy of a file or directory from multiple hosts.
