LMDBG is a collection of small tools for collecting and analyzing the logs of malloc/realloc/memalign/free function calls. Unlike many others, LMDBG does not provide any way to detect overruns of the boundaries of malloc() memory allocations, as this is not the goal. Like most other malloc debuggers, LMDBG allows detecting memory leaks and double frees. However, unlike others, LMDBG generates full stacktraces and separates the logging process from analysis, thus allowing you to analyze an application on a per-module basis.
Tartarus is a backup script designed to make backups of dedicated servers easy. It employs a range of standard Unix tools to achieve this goal, to simplify disaster recovery even when only a minimal rescue system is available. Archives can be stored on-the-fly on FTP servers as well as in the local filesystem, while a plugin system allows adaption to a wide range of usage scenarios. The use of LVM snapshots and the creation of differential backups are also included, as is an expire script to remove older archives from an FTP site.
The Amazing Awk Assembler (aaa) is a primitive assembler written entirely in awk and sed. It is quite slow, the input syntax is eccentric and rather restricted, and error checking is virtually nonexistent, but it does work. Furthermore it's very easy to adapt to a new machine, provided the machine falls into the generic "8-bit-micro" category.
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.
Dim is a utility to help you track the changes of items (sets composed of multiple files). It provides commands to handle the complete lifecycle of version control operations: create a library, register users (code authors), create items, save local versions, branch, clone, export, import, remove, merge, archive, replicate library content over the network or the filesystem, and access the full history and browse differences at the library, item, file, line, or word level. Dim is a single self-documented POSIX shell script. It just uses standard Unix utilities like awk, diff, tar, and openssl.
