Free quality of service software for linux

Adaptive Quality of Service Architecture (AQuoSA) is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, lightweight and open architecture for supporting soft real-time applications with facilities related to timing guarantees and QoS, on the top of a general-purpose operating system as Linux.
At the core of the architecture there is an adaptive resource reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on their run-time requirements.
Timing guarantees are provided through an in-kernel reservation based process scheduler, whose services are exposed to applications through a well-designed API.
A supervisor performs admission control, so that admitting into the system new applications with timing guarantees does not affect the timing guarantees of already admitted applications. Also, it takes care of guaranteeing appropriate security policies in the assignment of timing guarantees to users and user groups, as configured by the system administrator.
A feedback-based QoS control layer may be optionally used by applications who want to keep their timing guarantees by using a CPU allocation that is continuously adapted according to their actual needs. This leaverages the programmer, within certain limits, to hard-code any particular reservation amount within the application, because the best allocation is found out automatically at run-time. Also, this enhances the possibilities for the system to host additional QoS controlled applications. The available control algorithms are well founded on formal scheduling models and control theoretical results.
Enhancements:
- This release introduces a couple of flags useful when creating servers. If QOS_F_PERSISTENT is enabled, a server is allowed to exist beyond detach of the last task. If QOS_F_SOFT is enabled, a server tasks are scheduled by the Linux default scheduler/policy, when outside of the server reservation.
- Also, various stability issues in destroying servers have been fixed, also thanks to a new release of the generic scheduler patch for the Linux kernel (gs-2.2).

Son of Service (SOS) is a multiuser volunteer management database for non-profits, charities, schools, churches, and clubs. SOS will keep track of your volunteers, their contact information, availability, work history, comments, reminders, and relationships.

It will help you quickly find the right volunteer for the job and e-mail him, and it will make reports about how you are using volunteers.

SOS is a helpful tool for organizations with many volunteers or multiple volunteer coordinators.

Your organization helps people for free, and your volunteers work for free. So you know there is a "free lunch."

SOS is free. Its free from charge: notice there is no menu option for purchasing or ordering. But SOS also provides freedom from many restrictions. Download the program, install it, and use it without buying expensive licenses.

Use it on as many systems with as many users and volunteers as you have. Use your choice of server operating system and RDBMS. (You dont need to buy a RDBMS or other server software.) You can even modify SOS to meet your specific needs because the full source is available to you.

QAA is a XUL Mozilla Firefox extension that performs a user supplied test list on a Web application. Test sessions can be defined by example.
A report is generated when sessions are replayed.
Enhancements:
- This release can load and save .qaa files (Quality Assurance Agent file format), record a journey in the tested site using definition by example, and perform a test bench with a log style report.

The Simple RSS Service (SRSSS) generates and serves RSS feeds through a common interface via CGI-enabled webservers. It uses modules to extract items for feeds from various sources, and has a virtual filesystem where feeds can be read by CGI-clients.
The package contains everything needed to start providing RSS feeds, including server and CGI programs, and has support for PostgreSQL, MySQL and MimerSQL.
Main features:
- Modular and clean design based on object oriented C++
- Resource-friendly functions that keeps the load down on web- and database-servers by only parsing data and generate new feeds when required, instead of at every request.
- Interface for run-time loading of modules for data-extraction
- A virtual filesystem stored in shared memory
- Feed extraction via CGI program for easy integration in any CGI-enabled webserver
- A trigger-system that allows external sources to trigger daemon software to fetch new updates
- Easy configuration via a configfiles
- Designed for easy integration towards SQL servers etc
- Support for NetBSD, FreeBSD, OpenBSD and Linux.
Modules:
These modules are currently available for RSS item extraction:
mod_pgsql
This module allows the RSS daemon (rssd) to extract items for RSS feeds from a PostgreSQL database. It can select an entire column as description field for the feed, or base it on a pre-formated string in which variables are replaced with values from columns returned in the SQL query.
This module also support triggering, where any client connected to the same database is able to trigger RSSD to fetch a new update via the SQL LISTEN and NOTIFY functions.
mod_mysql
This module integrates RSSD with the MySQL database, allowing it to produce RSS feeds based on any information stored in databases running on MySQL. The module allows the user to run just about any SQL query supported by the database to extract the needed information to create a feed.
Mod_mysql does also support pre-formated strings to generate the description for each RSS item it produces.
mod_mimersql
This module allows the RSS daemon to fetch items from the MimerSQL database.
The module allows the user to run just about any SQL query supported by the database to extract the needed information to create a feed.
Mod_mimersql does also support pre-formated strings to generate the description for each RSS item it produces.
mod_template
This is a template-module that can be used as a starting-point when developing new modules. It is usable, but does not really provide a usable feature.

epstools service menu is used to create a tiff preview inside an eps file.

If a preview exists, it is replaced by the created one.

Peco::Service is a Perl module with service specifications for Peco IoC containers.

SYNOPSIS

use Peco::Service;

$service = Peco::Service->new( $class, @depends, $create, %attrs );
$service = Peco::Service::Factory->new( ⊂routine, @depends );
$service = Peco::Service::Constant->new( $value );

SERVICE TYPES

Peco::Service

A generic service registration class.

Peco::Service::Factory

Factory service registration class. Takes a coderef which is called each time this service is accessed.

Peco::Service::Constant

For constant or scalar values.

dl Download Ticket Service project is a minimalist and rough download ticket service with automatic expiration, written in PHP. Ive been using this service as an email-attachment replacement for my company, but there are no plans on extending it. It will remain minimal: no fancy features, just bug fixes.
Installation:
Copy the "htdocs" directory to a directory of choice under your web server. Configure the needed parameters inside "include/config.php" to reflect the external url, main password, etc. The "include" directory must not be accessible: if you use apache, the included .htaccess file should be sufficient; consult your web server documentation otherwise.
A spool directory outside of the web server root must be accessible to the web server process. In the example "include/config.php" this is configured as "/var/spool/dl". If you web server runs as "nobody:nogroup", issue:
mkdir -p -m770 /var/spool/dl
chgrp nogroup /var/spool/dl
to create correctly this directory.
The maximal upload limit is determined by several PHP configuration parameters:
file_uploads: must be "On".
upload_tmp_dir: ensure enough space is available.
upload_max_filesize: change as needed.
post_max_size: must be at least 1M larger than upload_max_filesize.
The upload limit as shown in the submission form is determined automatically from the upload_max_filesize parameter. You can also set these parameters with ini_set() inside "include/config.php" or through apaches directives to localize them to the installation path.
There are several bugs in the dba_open() function in PHP 4.x which cannot be fixed. If you can, upgrade PHP to at least 4.3.5. If you cannot upgrade, you need to configure the "$dbHandler" parameter to something available to your PHP installation (usually db3/db2/dbm) and use the Berkeleys DB "db4_load" utility to create an empty database:
echo | db4_load /var/spool/dl/data.db
echo | db4_load /var/spool/dl/user.db
chmod 770 /var/spool/dl/*.db
chgrp nogroup /var/spool/dl/*.db
Depending on your system, you may have to use "db3_load/db2_load/etc" instead of "db4_load". Sometimes these utilities are part of "db*-util" packages under several linux distributions. If you have PHP 4.3.5 or greater, this is done automatically.
Ticket expiration is performed automatically when any web page is requested. This means that expired downloads will still occupy space on the spool directory until a web page is first serviced. If you need to ensure that the spool is purged regularly (for very low traffic servers), setup a scheduled job that requests the "http://dl.example.com/d/" page. Under UNIX, setup a cron entry like this:
0 0 * * * wget -q -O /dev/null "http://dl.example.com/d/" > /dev/null
Version restrictions:
- Tested with all mayor and minor browsers.
