ACE is a platform-independent, collaborative text editor. It is a real-time cooperative editing system that allows multiple geographically dispersed users to view and edit a shared text document at the same time.

ACE is a program that allows multiple geographically dispersed users to view and edit a shared text document at the same time, thus facilitating efficient teamwork.

According to available knowledge, there is only one such application; it works well and has reached widespread use. Unfortunately, it is limited to the Mac platform. ACE is the first collaborative text editor that runs across all major platforms, including Windows, Linux, and Mac.

First of all, ACE is a simple text editor with standard features such as copy/paste and load/save. Multiple documents can be edited at the same time. Furthermore, ACE can share documents with other users on different computers, connected by communication networks.

ACE also discovers users and their shared documents automatically in a local area network. Users can opt to join any discovered shared document. For all this, no configuration is necessary because it is based on zero-conf networking (also known as Bonjour or Rendezvous).

Once a user has joined a shared document, he can freely edit the document at the same time with all participants as a virtual team. So-called awareness information helps to avoid unnecessary conflicts (i.e. two users editing at the same time and text location).

Awareness information includes the cursor and the currently selected text of the other users marked with the color of the respective user.

The heart of the application is a concurrency control algorithm based on the innovative concept of Operational Transformation, which allows for lock-free editing of a document by multiple users. It imposes no editing constraints and resolves all conflicts automatically.

The algorithm overcomes one of the most significant challenges in designing and implementing real-time collaborative editing systems, namely consistency preservation. That is to ensure that at quiescence (i.e. when no messages are in transit) the shared document is identical for all participants.

This algorithm was implemented as part of the semester project and forms the foundation of ACE.

ACE builds upon open technologies such as BEEP (RFC 3080) and zero-conf networking; all this leaves the possibility open to communicate even with different applications that understand the public protocol of ACE.

Web-based file manager is a small set of files that will turn your existing web server into a web-based file manager. As long as youve got php support enabled, you should be ready to go.

I recommend creating a directory on your server just for the file manager files and the files youre going to put up there. The file manager is provided as is, there is no warranty of any kind. Having said that, Ive been using it myself for a few years without problems.

You can dramatically increase the safety of your information by using strong passwords for all your online accounts.

Password Generator can generate fixed length passwords using custom character set, readable passwords using dictionaries.
It can also generate universally unique identifiers (UUIDs).

To make dictionary based passwords as secure as possible, you are able to configure the generation algorithm as follows:

1. Configure which dictionary to use. The more words in the dictionary, the greater your security.
2. How many dictionary words will be used in the password.
3. You can define the what password separator should be used.

The AmascoreSearch Widget starts a keyword search on amascore.com. You may save your personal settings (product category, prefered store) and have multiple widgets with different settings running.

Amascore is a robust scoring algorithm for book searches based on Amazon customer reviews. The scoring algorithm will present your search results in a better, more reliable ordering. The score is visualized together with a confidence interval which represents the reliability of the score.

In contrast to search engines like Google you should phrase your search such that it generates many (>20) results. The amascore server calculates a score for each book bases on a diversity of data, e.g. customer reviews, reliability of customer reviews, popularity, age (as an optional criteria). The amascore methodology is superior to the calculation of a simple mean customer review and results in much more reliable assessment of the book.

Diffraction is an important physical effect inherent in all wave phenomena. Fraunhofer and Fresnel diffraction are two important classes of diffraction. Fraunhofer diffraction involves coherent plane waves incident upon an obstruction. Fresnel diffraction is the same, except that the waves are spherical, effectively originating from a point source.
Fresnel Diffraction Explorer is based on an efficient algorithm to calculate numerically a Fresnel diffraction pattern using any two-dimensional aperture.
It is a simple exercise to show that Fraunhofer diffraction by an aperture is mathematically equivalent to the Fourier transform of the aperture shape. Because the integrals describing Fresnel diffraction are so intractable, however, Fresnel diffraction patterns have few analytical solutions, even in one dimension. ... A calculation in two dimensions is even more problematic.
Enhancements:
Universal Application release for Intel- and PowerPC-based Macs running OS X. Clusters of any combination of Intel or PowerPC Macs can be used in a Fresnel diffraction calculation.
Other updates:
- OS X-compliant icons, dialog boxes, including sheets and antialiased text.
- Endian conversion for file and disk storage as well as sending data over the network.
- Adaptations to bundle formats and Xcode.
- When using multiple wavelengths, FDE can export to QuickTime in addition to PICS.
- Establishment of a data fork only file format.

emboss (tinted) is a color effects plug-in that creates an ‘emboss’ effect on your clip. There are multiple ways of embossing a clip, and this plug-in takes the most basic approach by enhancing strong contrasts. Internally, it creates a grayscale image (which contains the embossed image), which can be mixed back into the original clip.

As expected, we have taken the emboss algorithm, and dragged it a few miles further afield for even cooler effects. Since at the heart of the algorithm is a difference engine, we thought it would be fun if the difference was displayed against a reference color. The result was the ‘tinted’ part, which is a really nice addition to the base effect.

Used with extreme settings, this plug-in produces similar results to our ‘edge detect’ plug-in.
