Makepp, a build program that has a number of features that allow for reliable builds and simpler build files, is a drop-in replacement for GNU make. It supports almost all of the syntax that GNU make supports, and can be used with makefiles produced by utilities such as automake. It is called makepp (or make++) because it was designed with special support for C++, which has since been extended to other languages like Swig or embedded SQL. Some features that makepp adds to make are: greatly improved handling of builds that involve multiple makefiles (recursive make is no longer necessary); automatic scanning for include files; rebuilds triggered if build command changes; checksum-based signature methods for reliable builds, smart enough to ignore whitespace or comment changes; extensibility through Perl programming (within your makefile); repositories (automatically importing files from another tree); and build caches (not recompiling identically what a user of the same cache already did).
ack is a tool like grep, optimized for programmers. Designed for programmers with large heterogeneous trees of source code, ack is written purely in portable Perl and takes advantage of the power of Perl's regular expressions. It searches entire trees by default while ignoring Subversion, Git, and other VCS directories and other files which aren't your source code. It uses Perl regular expressions to find just what you want.
nrun is a tool that runs a single command or script on multiple target servers synchronously. ncopy will copy a file or directory to multiple target servers. The underlying remote access mechanism is interchangeable, and currently supports ssh, nsh, rsh, and local execution modes. The return code and all command output is logged.
PerlShare is a DropBox drop-in to create your own private file sharing "cloud". It consists of two parts; a client and a server. The server part lets you configure a Linux machine to accept PerlShare clients. PerlShare behaves a lot like DropBox. On collisions, for example, it creates conflicted copies. The workhorse for synchronization is Unison, a very reliable piece of software from Pascal Bach.
CDimg|tools is a set of commandline tools to inspect and manipulate CD/DVD optical disc images in formats uncommon on free Unix-like systems (like GNU/Linux or BSD). It makes it possible to convert .NRG Nero images, to demultiplex RAW+96 image files containing both stream data and sub-channel data, to decrypt CSS-scrambled VOB files, and to decrypt CSS-scrambled DVD Video image files.
ddserver.pl is a simple, small Perl script that acts as a DynDNS-compatible and ZoneEdit-compatible dynamic DNS server. It also provides an HTML Web interface, operating as a CGI script, and has been tested within Apache and lighttpd Web servers. It creates and maintains bind9 named.conf(5) zone files. Simple zone-specific templates and username/password ACLs are supported.
Bedtime controls the bedtime of your children by automatically disconnecting their devices from your Internet connection. It does this by replacing your ISP router as the source of IP addresses, which allows it to learn all the devices on your network and control their access. Parents can log into a Web interface, link devices to children, and set their bedtimes for school nights and weekends. Misbehaving children can be grounded, or children's access can be extended as a reward.
