Free dovecot 1.0.2 software for linux

Dovecot project is an open source POP3 and IMAP server for Linux/UNIX-like systems, written with security primarily in mind. Although its written in C, it uses several coding techniques to avoid most of the common pitfalls.
Dovecot can work with standard mbox and maildir formats and its fully compatible with UW-IMAP and Courier IMAP servers implementation of them as well as mail clients accessing the mailboxes directly.
Its easy to migrate from them to Dovecot. I have also plans to support storing mails in SQL databases.
Dovecot is easy to set up and doesnt require special maintenance. Only thing you need is to get the authentication working properly - if your users are in /etc/passwd theres hardly anything you have to do.
Dovecot should be pretty fast. There are still some optimizations that could be done, but I believe it already beats most other IMAP servers in overall performance.
This is mostly because of index files that Dovecot maintains; instead of having to scan through all the data in mailbox, Dovecot can get most of the wanted information from index with little effort.
Dovecots indexes can scale to huge amount of messages per mailbox with hardly any noticeable slowdown. Ive tested only up to 367000 mails, but millions of messages should be no problem.
Dovecot takes very little memory. Most of it goes to mmap()ed index and mailbox files, meaning that if operating system is low on memory, it can simply drop those memory pages without having to store them in swap.
Connections are handled in separate processes, each one currently using around 100kB of swappable memory. Some extensions like SORT and THREAD will require more memory to work though.
Dovecot is fail safe. Indexes could potentially be quite a large problem maker, but Dovecot does sanity checks to all data before using it to avoid crashes and other problems.
Any kind of crash is considered as bug and will be fixed - even if it happens only by deliberately poking the index files.
Main features:
- Dovecot should be quite ready for use with normal IMAP clients.
- Complete IMAP4rev1 support.
- Supports THREAD and SORT extensions, required by many IMAP webmails.
- Complete TLS/SSL support
- IPv6 ready.
- Shared mailboxes arent yet supported.
- Maildir++ quota isnt yet supported. Hard filesystem quota can also be problematic.

Vobcopy copies DVD .vob files to harddisk, decrypting (if you have libdvdcss installed) them on the way (thanks to libdvdread and libdvdcss) and merges them into file(s) with the name extracted from the DVD.
It checks for enough free space on the destination drive and compares the copied size to the size on DVD (in case something went wrong during the copying). Vobcopy project without any options will copy the first title into files of 2GB size into the current working directory.
There is one drawback though: at the moment vobcopy doesnt deal with multi-angle-dvds. But since these are rather sparse this shouldnt matter much.
Enhancements:
- A segfault in the log file writing routine was fixed.
- Small fixes and experimental "step over the bad part" code were added.

KFocus is a personal project management program with support for task lists and log books.

Supports:

- Categorizing tasks into projects
- Viewing how much time you have left to complete a task
- Creating logs of completed tasks
- Scheduling followup tasks when a task is completed
- Scheduling tasks to start in the future

Installation:

You need to install klik on your system to run cmg applications.

Press Alt-F2 and paste:

wget klik.atekon.de/client/install -O -|sh

lcdmod was written because there was no nice way of controlling these displays from a computer under linux, most other software written to control these displays run in user space, and/or dont support all the features of the displays.
lcdmod allows users to easily intergrate the LCD, in its simplest form, into shell scripts, C code, et cetera by simply writing ASCII to the device file. But also provides an interface to many of the more powerful features of the display and module through that same interface.
Main features:
- Character device driver for all HD44780 compatible displays.
- Fast 8 bit mode.
- Support for all screen sizes.
- User definable fonts, and mapping.
- proc filesystem entry shows module configuration and current display state.
- Driver emulates most control characters of a vt52 terminal.
- Support for multiple wiring schemes.
- No LCDProc

jettalk provides a console-based blackboard communication program.

With jettalk multiple users can edit in a text area simultaneously. This can be used for project coordinance, playing games, or just chatting.

Klep is Yet Another virtual flashcard program, which helps in putting information into ones short term memory.
Klep has many features not commonly found in virtual flashcard programs, including export to memaid so that material learned in Klep can be retained in the long term, support for images, support for multiple choice questions, and a bunch more.
Klep uses wxWidgets, so it should theoretically work in UNIX-likes (GNU/Linux, Mac OS X, freeBSD, etc), Windows, OS/2, and others, although binaries are currently only available for GNU/Linux and Windows.
Enhancements:
- Some bugs related to images were fixed.

Libqrencode is a C library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robustness.
Libqrencode supports QR Code model 2, described in JIS (Japanese Industrial Standards) X0510:2004 or ISO/IEC 18004. Currently the following features are not supported:
- ECI and FNC1 mode
- Structured Append Feature
- Micro QR Code
- QR Code model 1

Nanoserv is object oriented and features native support for TCP with SSL/TLS and UDP connections, multiplexing and forking listeners, handlers for raw connections, line input, HTTP, SMTP, XML-RPC, Syslog, transparent inter-process communications with forked handlers, and more.
Main features:
- 100% object oriented
- native support for TCP with SSL/TLS and UDP connections
