Free food production software for linux

Fnord is a Linux distribution designed to be built from source and maintained manually. This allows the administrator maximum control over the system.

Unlike other built-from source systems, Fnord is not a toy; it is intended as a production Linux system (in fact, Fnord has been running on all of FnordNets machines since 2000).

Fnord includes a ramdisk-based utility system for initially configuring the target system, a pre-built environment that allows for building the system, full source code for the base system, and source for many other packages.

DryDock is a Web publishing application that implements a development/production Web site pipeline. It codifies an approval process that forces users to approve all Web site changes before they go into production.

Sometimes, on a web server, system administrators are often ill-equipped to determine who created the document, why its being served, how long its been publicly viewable, and how its changed over time.

To police our own website, we create DryDock. DryDock is a web publishing application that governs the replication of content from a developmental, or staging web tree to a production web tree (ideally placed on a second server). DryDock codifies a formal approval process that forces management to approve all web site changes before those changes are put into production. Users never interact directly with the production web tree; DryDock updates it on their behalf.

ldapdns is a fast and rhobust root-nameserver that can outperform bind and djbdns on medium to large installations, and will scale well both up and down.

the secret is that ldapdns uses a threaded core, and takes advantage of an external directory. its extremely simple, and it does not run under user-control as root.

its ideal for small and large installations, because it queries the ldap server directly, updates are immediate. you dont have to rebuild constant databases, or wait for bind to get its shit in gear.

but ldapdns is a work-in-progress. i use it on a production network, as do many others. but its up to you to make it best for your network.

mysqlrowcopy is a tool that generates insert statements from result sets. It produces output similar to what might result from running mysqldump on a single SELECT query.

This project helps eliminate some of the tedium of moving data between QA and production MySQL databases.

Build:

To build mysqlrowcopy, you should run:

./configure
make

A mysqlrowcopy and mysqlrowcopy.debug file are created. They have identical functionality, the .debug version simply has debugging symbols built in (for gdb).

Since mysqlrowcopy is probably going to be I/O bound with modest CPU and RAM usage, the only reason to even build a 64-bit version is to work around potential issues in dynamic linking 32-bit binaries against 64-bit libraries.

RECIPES

1. Migrating a MySQL user account reaper from QA server to a production server.

e.g. MySQL database server qa3.example.com to prod1.example.com:

$ mysqlrowcopy -h qa3.example.com
SELECT * FROM db WHERE User = "reaper" mysql db > reaper.sql
$ mysql -h prod1.example.com mysql < reaper.sql

You could of course simply pipe the output of mysqlrowcopy into mysql and skip the intermediate file.

(Dont forget to RELOAD PRIVILEGES afterwards)

2. Keep your test environment up to date. Populate it with production data every 24 hours. You could run this sequence from cron once a day:

$ mysqlrowcopy -h finance-db.example.com
SELECT * FROM stocks WHERE modified > DATE_SUB(NOW(),INTERVAL 24 HOUR)
finance stocks > day-stocks.sql

$ cat day-stocks.sql | mysql -h finance-test.example.com finance

3. Copy data between tables on different servers that have some similar fields.

Youve got common data in table Zip on a production database:

mysql> desc Zip;
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| ZIPCode | varchar(5) | | PRI | | |
| ZIPCodeType | char(1) | YES | | NULL | |
| City | varchar(32) | YES | | NULL | |
| CityType | char(1) | YES | | NULL | |
| State | varchar(32) | YES | | NULL | |
| StateCode | char(3) | YES | | NULL | |
| AreaCode | char(3) | YES | | NULL | |
| Latitude | varchar(12) | YES | | NULL | |
| Longitude | varchar(12) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
9 rows in set (0.00 sec)

And youve got table ZipPosition in a research database:

mysql> desc ZipPosition;
+-------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+-------+
| ZIPCode | varchar(5) | | | | |
| Latitude | varchar(12) | YES | | NULL | |
| Longitude | varchar(12) | YES | | NULL | |
+-------------+-------------+------+-----+---------+-------+
3 rows in set (0.00 sec)

You want to load data from production Zip into research ZipPosition.

$ mysqlrowcopy -h production SELECT ZIPCode,Latitude,Longitude common ZipPosition > pos.sql
$ cat pos.sql | mysql -h qa research

Note how we specify ZipPosition on the first line to tell mysqlrowcopy what the destination table is going to be.

X-evian is a Live-CD, a complete operating system which installs automatically from the CD-Rom in RAM memory by means of a process of automatic hardware detection.

This makes it possible to "parasite" a PC without leaving any trace?without touching the hard disk and without interfering with the operating system or the files already installed on the PC. X-evian also includes a utility for installing the contents of the CD automatically onto the hard disk (without having to erase Windows).

Debian GNU/Linux is much more than an operating system: it is an entire system of program distribution, installation and management built around the Linux kernel (the core of the operating system). Debian GNU/Linux consists of about 10,000 different programs, nearly all of which are free software, bundled and classified for integrated operation.

X-evian is a selection and compilation which has been carefully chosen and configured for activist users, for liberated cultural, technological and social production. But Debian is much more than "a complete operating system and an infinite number of programs".

Debian is the largest independent free software community on the Net and one of the most firmly established and stable techno-political projects in cyberspace. X-evian is an easy preconfigured way of introducing the user to the best of the resources of this Debian.

The power of digital recombination, reproduction and transmission has enabled the cognitariat (the workers of the immaterial production networks) to organise its own production transversally. But this transverse self-organisation would not have been possible without a format that would protect the collective work.

This is copyleft. "Copyleft uses copyright law, but flips it over to serve the opposite of its usual purpose: instead of a means of privatizing software, it becomes a means of keeping software free. The central idea of copyleft is that we give everyone permission to run the program, copy the program, modify the program, and distribute modified versions?but not permission to add restrictions of their own.? Stallman, R. (http://www.gnu.org/gnu/thegnuproject.html).

Copyleft hacks into the legal system of copyright to champion the freedom of knowledges and techniques. X-evian is the product of the recombination, copying and transformation of these knowledges. X-evian can therefore be freely copied, distributed, modified, recombined and used (provided any modification is also free).

But its not only the software that can be copylefted: the design, images, texts, technical documents, music and videos included in X-evian are also free. X-evian therefore forms part of the cycles of immaterial production, liberated from the info-capitalist restriction on the circulation of knowledges and techniques, and its devices of production and consumption (factories, companies, shopping centres, etc.).

Liberated immaterial production does not operate along the lines of the development-production-sale-consumption sequence, but rather follows interactive cycles of development-use-development, looped in backfed hypercycles of projects, groups and individuals (X-evian, metabolik, hacklabs, sindominio, Debian, Linux, etc...).

X-evian is therefore also a community of development and experimentation from free software towards a different technological, cultural and social model, in which production and use merge in cooperative horizontal communities working outside market interfaces, innovation restricted by patents and commercial interests and the consumerist use of technology.

This edition of X-evian seeks to explicitly support copyleft philosophy, motivations and practices, and therefore includes an organised selection of copyleft materials (chats, texts, manuals, etc.).

The Pure Perl RayCaster is a small simple Ray casting application written completely in Perl without using any 3D API library or OpenGL. For the GUI, Pure Perl RayCaster uses wxPerl (WxWindows port to Perl).

Pure Perl RayCaster can load a 3D object from a file (in RAW format), display the object in wireframe perspective view, allow to orbit and zoom your camera and produce a user defined size ray casting image of the current view in a predefined color theme with or without smooth shading.

Pure Perl RayCaster is not a professional production tool for 3D image generation. It is well suited for educational purposes, in order to study, understand, tweak and try well known fundamental 3D Computer Graphics techniques.
