smf-sav is a lightweight, fast and reliable Sendmail milter that implements a real-time Sender e-Mail Address Verification technology. This technology can stop some kind of SPAM with a spoofed senders e-Mail address.
Also it implements a real-time Recipient e-Mail Address Verification technology. It can be useful if your machine is a backup MX for the recipients domain or if your machine forwards all e-Mail messages for your domain to another (presumably internal) e-Mail server. Sendmail Sender Address Validator is written in C.
Main features:
- friendly hosts/networks whitelist;
- SMTP AUTH support;
- strictly RFC-2821 compliant MX callback engine;
- tolerance against non RFC-2821 compliant e-Mail servers;
- blocking of e-Mail messages with a spoofed senders e-Mail address;
- recipients e-Mail address verification with an authoritative e-Mail store in gateway mode;
- slow down of recipients e-Mail address brute force attacks in gateway mode.
Enhancements:
- Whitelisting by a PTR (reverse DNS) record was implemented.
- Whitelisting by an envelope recipient email address was implemented.
- The option to ignore tempfailed results of SAV was implemented.
- The option to refuse email messages from systems that dont accept the null reverse-path was implemented.
- Tempfail and fail results TTL settings were segregated.
- Progressive slowdown of brute force attacks on a recipients email address was implemented.

Parallel Three-Dimensional Fast Fourier Transforms, dubbed P3DFFT, is a library for computational computing in a wide range of sciences, such as physics, climatology, chemistry.
This project was developed at SDSC by Dmitry Pekurovsky as a product of a Strategic Applications Collaborations (SAC) project.
Main features:
- Parallel implementation with 2D data decomposition, overcoming an important limitation to scalability of other 3D FFT libraries implementing 1D, or slab, decomposition.
- Optimized for parallel communication and single-CPU performance.
- Built on top of well-optimized and flexible 1D FFT libraries.
Enhancements:
- Assorted minor bugfixes and code speedups.

Katapult-Fast Track project is a Katapult fork based on the KDE SVN repository. It fixes several outstanding issues of upstream Katapult. Unfortunately, Katapult development stagnated and no progress has been made upstream for half a year. Hopefully someone from the team will actually reply to my e-mails so Katapult development can continue. If not this fork will need a name (Im obviously leaning towards Fast Track) and will be a separate project altogether.
Improvements over last stable Katapult release:
- Support for multiple results (Press up or down keys to see more results)
- Support for multiple actions (Press left or right keys to see more actions)
- Adaptive search
- Threaded architecture
- Non-blocking DCOP calls
Kudos to the team for providing the framework for multiple results, multiple actions, and multithreaded catalogs.
Caveats:
- Currently, only the program and bookmark catalogs actually return more than one result at a time.
- Only the program catalog supports adaptive search.
- Only the amarok catalog has multiple actions.
What this means for YOU:
- The amarok catalog should not slow down Katapult if you have a big collection of songs.
- The amarok catalog can now queue songs and add songs to the current playlist
- The program catalog will adapt to your launching preferences (i.e. no more "Konquest" results when all you want is "Konqueror")
- You no longer have to type more letters (press the down key to choose something else)
What is still lacking:
- Testing. Especially for the amarok catalog. I only have a couple of GB worth of songs so I cant speak for everyone but this should be an improvement over the last release.
- Spell catalog. Ive tried everything to get KSpell to play nice with separate threads (i.e. call KSpell in the main thread, block the worker thread till KSpell is done, then pass the result to the worker thread) but it just wont work.
- Composite support. I havent applied my own real transparency patch. Dont try to apply it here because it was made to specifically work against 0.3.1.4.
Installation:
Extract the files. cd to the created directory. Then ./configure and make and then install as root.
For any problems, either leave something here or post something at the Katapult forums. Ill get back to you as soon as I can. Please include how to reproduce your problems.

wxDownload Fast (also known as wxDFast) is an open source download manager.
Besides that, it is a multi-threaded download manager. This means that it can split a file into several pieces and download the pieces simultaneously.
Created in C++ using the wxWidgets(wxWindows) library.
Main features:
- Faster downloads (with Segmented/Multi-threaded/Accelerated transfers)
- Download resuming (Pause and restart where you stopped)
- Download scheduling
- Organizes files you have already downloaded
- View server messages (HTTP, FTP, file://). No HTTPS support.
- Available in multiple languages and easily translated. Now available in Portuguese [Brazil], Spanish, English and German
- Connection to FTP servers which require a password
- Calculates the MD5 checksum of downloaded files so they can be easily verified

Namistai project is a piece of software that connects an HTTP-client (browser/user-agent) to Windows file shares (also known as SMB or CIFS).
When to use Namistai?
When:
- you want to give access to files but dont need all the functionality of windows shares.
- you have a slow link somewhere in your network connection.
- you dont have root access (but you have permission from your sysadmin
- you dont want to run a webserver.
- for some reason, your environment cant read SMB or CIFS.
When is Namistai NOT needed?
When:
- you have a fast network connection.
- all your computers are in the same network (you have smb mounts and standard windows sharing for that).
- you dont have perl.
