TurnKey Drupal is an extremely easy way to get up and running with Drupal in just a couple of minutes. It's a pre-integrated turnkey server based on Ubuntu that is packaged as a Live CD image capable of supporting installations on both physical and virtual machines, including VMWare, Xen, VirtualBox, and KVM. It features a small footprint, automatic security updates, a rich Web administration interface, and an easy to use configuration and installation console. It includes a dozen popular Drupal extensions for convenience.
HelenOS is a microkernel-based multiserver operating system designed from scratch. By decomposing the operating system functionality into tens of isolated but intensively communicating userspace servers, it provides a computing environment that has several virtues such as flexibility, increased robustness, well defined explicit interfaces, and smaller complexity of individual components. HelenOS does not aim to be another clone of Unix or some other legacy system and is not POSIX-compliant (even though it may seem POSIX-similar at times). Instead, the goal has been to design it according to what is the most elegant and right thing to do. What makes HelenOS unique among the other multiserver operating systems is its multiplatform and multiprocessor microkernel. It will run on seven different processor architectures ranging from a 32-bit uniprocessor little-endian ARMv4 to a 64-bit multicore big-endian UltraSPARC T1.
WISP-Dist is a modular embedded Linux distribution for wireless routers, but can be used for other purposes as well. The entire system fits in 8 MB flash/16 MB RAM. Highlights include an easy-to-use menu interface, commandline access, an Access Point mode (on selected cards), OSPF/RIPv2, bandwidth shaping, NAT, Layer 3 (proxy arp) bridging, and other goodies. The goal is to create an open, customizable, and easy-to-use solution for wireless routers.
HTB-tools Bandwidth Management Software is a suite of tools that help simplify the difficult process of bandwidth allocation, for both upload and download traffic, using the Linux kernel's HTB facility. It can generate and check configuration files. It also provides a real time traffic overview for each separate client.
QuickSwitch lets you switch network profiles on the fly (IP address, DNS, routes, NFS shares, etc.). There is a command-line configuration mode by which you can change your entire network setting in one line (including DNS and routing table). It is highly configurable, supports DHCP/BOOTP/NIS/NFS/etc., and also includes a curses-based GUI which you can use as a profile selector on startup.
Platform Independent Petri Net Editor (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively. A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations. Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification. PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.
