isbnsearch project is an ISBN search tool with a permanent cache.
isbnsearch provides a simple method for retrieving information about any book using only an ISBN or EAN barcode.
It is intended to provide assistance for online libraries, user groups, or individual users, and is designed in such a way to provide a distributed ISBN database query system.
Users can choose to view the summary information (author, title, publisher, date, edition, subject, ISBN) as HTML, XML, or a pre-formatted SQL statement.
Enhancements:
- config/newservers.sql, config/servers.sql: devel v0.5 release
- config/isbn.pl, config/isbnsync.pl, config/fallbackisbn.pl:
- devel/scripts/gateway.sh, devel/scripts/asyncz.sh,devel/asyncz.txt: tweaks

A large and flexible palette of time constraints:
- Constraint activities preferred times (you can specify a set of activities by teacher, subject, subject tag or students and a set of preferred or allowed periods).
- Constraint activities same starting hour
- Constraint activities same starting time
- Constraint activities not overlapping
- Constraint activity preferred time (to specify for an activity a preferred day, hour or both)
- Constraint activity preferred times
- Constraint basic compulsory time

- Constraint students set early (to make the students set begin as early as possible the activities)
- Constraint students no gaps
- Constraint students set no gaps
- Constraint students (set) max hours daily
- Constraint teacher(s) max hours daily
- Constraint students set not available
- Constraint teacher max days per week
- Constraint teacher not available
- Constraint teachers max gaps per week
A large and flexible palette of space constraints:
- Constraint activity preferred room
- Constraint activity preferred rooms

JEXN project is a simple, yet powerful java class that can be added to any Java 1.3 or later application.
In the unfortunate event that the application crashes the virtual machine redirects the System.err stream to a small JSX (Java Serialisation to XML) powered server application.
The server then forwards the exception stacktrace on to a user specified email address.
Enhancements:
- Added to field email validation.
- Enabled user specification of email subject and from fields and the name of the application JEXN monitors.

Rosetta::TODO document maps out a rough development plan the Rosetta DBMS framework, so you know in roughly what order I plan to implement various features. When something is implemented, it will be removed from this list and instead be reflected elsewhere, such as the main documentation or the Changes files.

There are no specific time scales but you can assume that, at any given time, the handful of items at the top of the list should become available within a months time. Of course, the list is subject to be changed as I become better aware of circumstances, and that can be influenced by work done by other people.

GutenPy project is a comfortable text reader and catalog browser for Project Gutenberg.

GutenPy is written with Python GTK2, so all those nice clean fonts are available. This also allows it to run well on both Windows and Linux. It features handy bookmarking, line numbering, and word definition lookups (using a dict server).

The catalog browser can filter its booklist by Author, Title, and Subject using simple, or complex, regular expressions. Once the books are found a booklist of wanted items can be created and downloaded, or saved for future downloading.

Spammer is an anti-spam mail filter for the popular MTA Sendmail.

Spammer checks all IP-Addresses found in the mail header against a DNS blacklist (such as the one from Easynet, Spamcop or Osirusoft).

Depending on the configuration, Spammer rejects mails from well-known spam sources or tags them with an additional line in the header and a special prefix in the subject.

Spammer requires Sendmail to be compiled with milter support. If youre using Debian Linux you need to install the libmilter-package.
