TVGids Widget is a Dashboard widget for the Dutch TVguide site tvgids.nl.

I did the javascript coding for this widet, the design of the widget was made by Rik van Linden van den heuvell (http://rik.osxy.nl).

WoPeD (Workflow Petri Net Designer) is an open-source project developed at the Berufsakademie Karlsruhe under the GNU Lesser General Public License (LGPL).

The main goal is to provide an easy-to-use software tool for modelling, simulating and analyzing workflow process and resource descriptions using workflow nets, an extended class of Petri nets initially introduced by Wil van der Aalst (TU Eindhoven).

WoPeD is mainly indended to be used by researchers, teaching staff or students dealing with the application of Petri nets to the area of workflow or business process management. WoPeD has already been successfully used as modelling tool in lectures and student assessment projects.

Here are some key features of "WoPeD":

· Subprocess editing environment
· Capacity planning
· Move to Java 5 as minimum requirement
· Tokengame is subprocess-aware (step-over/step-into)
· Enhanced process structure treeview in editor sidebar
· Combined XOR/AND operators now fully implemented
· Complete GUI facelifting (icons, dialogs, editor usability, logo and many more)
· Refactoring and bugfixing in soundness analysis
· Added help contents for new functions
· Experimental feature: Quantitative analysis (capacity planning)
· Architectural rede

iMol is a free molecular visualization application for Mac OS X operating system. The program is an indispensable tool for chemists and molecular biologists. iMol allows loading molecules using several file formats: PDB, MOL2, HIN, CAR, ALC, BIO. The molecules can be saved as PDB or BIO files.

The BIO file stores all view and rendering settings (e.g. colors, lighting, orientation of molecules). iMol can easily handle both small and large molecules, it can load multiple molecules, move and rotate them independently.

iMol is able to measure angles, torsional angles, and distances between atoms. Molecules can be superimposed and RMSD (Root Mean Square Deviation) between atom coordinates can be calculated. Additionaly, protein chains can be structurally aligned to detect regions of high structural similarity. iMol can load multimodel PDB files and display them as a dynamics trajectory.

iMol uses OpenGL graphics to display molecules. The molecules can be rendered using various styles: wires, points, Van der Waals spheres, balls and sticks, polygons, strands, ribbon, cartoons, spring, tube, ladder. Individual atoms and/or residues can be selected and rendered independly.

The rendering styles can be mixed up to visualize complex molecular systems in a more convienient way. There are several predefined color schemes available (e.g. residuum order, secondary structure, hydrophobicity), as well as custom colors. Also, different materials (e.g. plastic, metal, glass) can be used. The rendered images may be exported as a bitmap, as a PostScript file, or as a POV-Ray file.

Several rendering effects are available, including automatic rotation, motion blur, depth cueing (fog), background gradient, perspective, and stereo projection (using both side-by-side and red/blue anaglyph methods). Various rendering parameters can be fine-tuned.

Snow Tracker is a screensaver. Youll see snowflakes. Theyll rotate and float around your screen, and when they get close to each other, youll see a nerdy proximity detector. Thats the Van Brink factor :)

BitRocket is a native (open source) BitTorrent client for Mac OS X. At the heart of its core resides the powerful libtorrent BitTorrent library.

BitRocket is a tool designed to be a good alternative to other Mac OS BitTorrent clients.

Here are some key features of "BitRocket":

UI Features:
· RSS support (Download .torrents from within the application)
· Integrated (Customizable) Search Engine
· Flexible Filtering
· Torrent Generator
· Live Info View
· UPnP and NAT-PMP Port Forwarding

Core(libtorrent) Features:
· Trackerless torrents (using a kademlia DHT)
· multitracker extension support (as specified by John Hoffman)
· serves multiple torrents on a single port and in a single thread
· gzipped tracker-responses
· HTTP seeding, as specified by Michael Burford of GetRight.
· piece picking on block-level (as opposed to piece-level). This means it can download parts of the same piece from different peers. It will also prefer to download whole pieces from single peers if the download speed is high enough from that particular peer.
· queues torrents for file check, instead of checking all of them in parallel.
· supports http proxies and proxy authentication
· uses separate threads for checking files and for main downloader, with a fool-proof thread-safe library interface. (i.e. Theres no way for the user to cause a deadlock).
· can limit the upload and download bandwidth usage and the maximum number of unchoked peers
· piece-wise, unordered, incremental file allocation
· implements fair trade. User settable trade-ratio, must at least be 1:1, but one can choose to trade 1 for 2 or any other ratio that isnt unfair to the other party.
· fast resume support, a way to get rid of the costly piece check at the start of a resumed torrent. Saves the storage state, piece_picker state as well as all local peers in a separate fast-resume file.
· supports an extension protocol.
· supports files > 2 gigabytes.
· supports the no_peer_id=1 extension that will ease the load off trackers.
· supports the udp-tracker protocol by Olaf van der Spek.
· possibility to limit the number of connections.
· delays have messages if theres no other outgoing traffic to the peer, and doesnt send have messages to peers that already has the piece. This saves bandwidth.
· does not have any requirements on the piece order in a torrent that it resumes. This means it can resume a torrent downloaded by any client.
· adjusts the length of the request queue depending on download rate.
· supports the compact=1 tracker parameter.
· selective downloading. The ability to select which parts of a torrent you want to download.
· ip filter.

FFT is an alternative traceroute program for displaying the route packets take to an IP network host. Unlike Van Jacobsons traceroute, which is available on almost every platform today, FFT uses TCP in order to elicit ICMP TIME_EXCEEDEDs or TCP_RST.

As a result, FFT often executes much faster and sees behind some configurations of packet- filter based firewalls. FFT has been around since 1998, but this is its first release on Darwin/MacOSX.

LFT, short for Layer Four Traceroute, is a sort of traceroute that often works much faster (than the commonly-used Van Jacobson method) and goes through many configurations of packet-filter based firewalls.

More importantly, LFT implements numerous other features including AS number lookups, loose source routing, netblock name lookups, et al. Though LFT has been around since 1998, its development effort has just recently resumed.

Certificate Import just imports digital Certificates via Drag&Drop into your Keychain and supports Certificates in popular Apache-Format (.der Files).

Whats New in This Release:

· Faster Processing
· New "Read Me"-File
· Changed Icon
· Internal Changes.
