Exceptions in C implements fully-functional nested exceptions with these constructs:

try
except
on
throw

Also, it allows to define various datatypes for exception object (default is int, can be anything from char * to struct foo *).

Compiling and running

Precodey straight forward.

admp@sols:~/excc/example$ gcc exception.c -c
admp@sols:~/excc/example$ gcc exception.o example.c -o example
admp@sols:~/excc/example$ ./example
Usage: ./example A B
admp@sols:~/excc/example$ ./example 100 2
100/2=50
Program is going to end its short life.
admp@sols:~/excc/example$ ./example 100 0
Caught up division by zero (100/0).
Program is going to end its short life.

pNRG project is a package for maintaining and visualizing network data, particularly suited for historical trend analysis of network resources.

pNRG doesnt need any explicit configuration and is able to auto-discover, mantain and graph new resources (either IPv4/IPv6 end hosts, network segments, MAC addresses, Autonomous Systems, etc.) as soon as they produce a traffic footprint.

pNRG at a glance:

* Easily displays network data collected through pmacct, regardless of the data source, ie. the network itself, NetFlow or sFlow.
* Straight to your preferred web browser from a couple of pmaccts memory plugins, without the need to configure or define anything.
* No need to rotate, mantain or update anything once the package is in place.
* Just a working installation of pmacct, RRDtool and an Apache supporting execution of CGIs are required.

While it has been over-simplified, specifically tailored to network usage and written from the scratch, most of its concepts are deeply rooted inside the NRG project. For the task, pNRG gets data from a couple of pmaccts memory plugins and relies over RRDTool for graphs and CGIs.

TagFu is a library for tagging entities (which can be anything with a url) with Tags or metadata. The project is implemented in Python and very closely mimics basic Python data structures.

Tags is a Python list of tags, Entities is a Python List of Entity objects, and Entity is a dict which contains all the key-value pairs for all tags associated to the Entity. The key is the Tag name and value is an arbitrary value, if no value is set, the tag is considered to be a simple tag.

The current direction of development is towards a C port to make binding to other languages easier, and the development of applications to use TagFu.

Apache::SiteControl is a Perl web site authentication/authorization system.

SYNOPSIS

See samples/site for complete example. Note, this module is intended for mod_perl. See Apache2::SiteControl for mod_perl2.

Apache::SiteControl is a set of perl object-oriented classes that implement a fine-grained security control system for a web-based application. The intent is to provide a clear, easy-to-integrate system that does not require the policies to be written into your application components. It attempts to separate the concerns of how to show and manipulate data from the concerns of who is allowed to view and manipulate data and why.

For example, say your web application is written in HTML::Mason. Your individual "screens" are composed of Mason modules, and you would like to keep those as clean as possible, but decisions have to be made about what to allow as the component is processed. SiteControl attempts to make that as easy as possible.

DEVELOPERS VIEWPOINT - EXAMPLE

In this document we use HTML::Mason to create examples of how to use the control mechanisms, but any mod_perl based system should be supportable.

A good mason component tries to do most of the perl processing in a separate block, so that simple substitutions can be made in HTML in the rest of the page. This makes it much easier for web developers and perl developers to co-exist on a project.

The SiteControl system tries to make it possible to continue to follow this model. You obtain a user object and permission manager from the SiteControl system. These are intended to be opaque data types to the page designer, and are defined elsewhere (see USERS). The actual web page component should carry these objects around without implementing anything in the way of policy.

Twibright Twig is an image gallery program. You have a directory with subdirectory structure with images. Twig generates for each image 3 levels of diminished images and 3 level of thumbnails.

Twig keeps a clickable structure of HTML files, each directory has an own HTML page with listing and each file has own HTML page with links to various sizes of the images under thumbnails and with EXIF information and image comment.

Twig can work with JPG and PNG images. Maybe also with GIFs but I am not sure.

If you change anything in the gallery (add directories, files, change files, delete files), you just need to rerun the "regen" script. Twig automatically detects all changes and updated in the HTML structure. Thumbnails and scaled down images are automatically regenerated if needed. Most time-intensive work is however not done if not necessary.
