Sun Grid Engine (SGE), previously known as CODINE (COmputing in DIstributed Networked Environments) or GRD (Global Resource Director),[2] is an open source batch-queuing system, developed and supported by Sun Microsystems. Sun also sells a commercial product based on SGE, also known as N1 Grid Engine (N1GE).

SGE is typically used on a computer farm or high-performance computing (HPC) cluster and is responsible for accepting, scheduling, dispatching, and managing the remote and distributed execution of large numbers of standalone, parallel or interactive user jobs. It also manages and schedules the allocation of distributed resources such as processors, memory, disk space, and software licenses.

SGE is the foundation of the Sun Grid utility computing system, made available over the Internet in the United States in 2006,[3] later becoming available in many other countries.

micro_httpd - really small HTTP server

A web server in dd/sh

"mini_httpd is a small HTTP server. Its performance is not great, but for low or medium traffic sites it's quite adequate. It implements all the basic features of an HTTP server, including:

* GET, HEAD, and POST methods.
* CGI.
* Basic authentication.
* Security against ".." filename snooping.
* The common MIME types.
* Trailing-slash redirection.
* index.html, index.htm, index.cgi
* Directory listings.
* Multihoming / virtual hosting.
* Standard logging.
* Custom error pages.

It can also be configured to do SSL/HTTPS and IPv6.

mini_httpd was written for a couple reasons. One, as an experiment to see just how slow an old-fashioned forking web server would be with today's operating systems. The answer is, surprisingly, not that slow - on FreeBSD 3.2, mini_httpd benchmarks at about 90% the speed of Apache. The other main reason for writing mini_httpd was to get a simple platform for experimenting with new web server technology, for instance SSL. "

"XORP is the industry's only extensible open source routing platform. It is in broad use worldwide, with thousands of downloads by companies and educational institutions and an active international developer community. Designed for extensibility from the start, XORP provides a fully featured platform that implements IPv4 and IPv6 routing protocols and a unified platform to configure them. It is the only open source platform to offer integrated multicast capability. XORP's modular architecture allows rapid introduction of new protocols, features and functionality, including support for custom hardware and software forwarding. "

"Why this book?

The Art of Unix Programming attempts to capture the engineering wisdom and philosophy of the Unix community as it's applied today — not merely as it has been written down in the past, but as a living "special transmission, outside the scriptures" passed from guru to guru. Accordingly, the book doesn't focus so much on "what" as on "why", showing the connection between Unix philosophy and practice through case studies in widely available open-source software."

"NanoBSD is a tool currently developed by Poul-Henning Kamp <phk@FreeBSD.org>. It creates a FreeBSD system image for embedded applications, suitable for use on a Compact Flash card (or other mass storage medium).

It can be used to build specialized install images, designed for easy installation and maintenance of systems commonly called “computer appliances”. Computer appliances have their hardware and software bundled in the product, which means all applications are pre-installed. The appliance is plugged into an existing network and can begin working (almost) immediately."

The appliance is plugged into an existing network and can begin working (almost) immediately.

The features of NanoBSD include:

Ports and packages work as in FreeBSD — Every single application can be installed and used in a NanoBSD image, the same way as in FreeBSD.

No missing functionality — If it is possible to do something with FreeBSD, it is possible to do the same thing with NanoBSD, unless the specific feature or features were explicitly removed from the NanoBSD image when it was created.

Everything is read-only at run-time — It is safe to pull the power-plug. There is no necessity to run fsck(8) after a non-graceful shutdown of the system.

Easy to build and customize — Making use of just one shell script and one configuration file it is possible to build reduced and customized images satisfying any arbitrary set of requirements."
