Free 0.91 software for windows

RF21 for Windows contains a scientific calculator, plotter, programming and numeric system in one.
It allows for permanent installation of a users own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago.
Each function self-reassembles when its name is called, autonomously searching the libraries for all components needed.
Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the programs numeric and plotting capabilities can be used.
Main features:
- Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, n-dimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer.
- Fast screenplots and an environment for designing printable plots, which may as well be exported to -.GIF and -.BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields.
- Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see authors homepage for a systematic reference of these

i.Hex is a small and free graphical Hex Editor for Windows. I got ticked off at all the lame shareware hex editors out there and just buckled down and wrote my own.
i.Hex is a software that allows you edit and view HTML files.
Main features:
- Doesnt load all the file at once. Just a pane of 64K is loaded at any given time, thus it can edit/view very large files almost instantly.
- Recent file menu.
- Doesnt use the registry.
Usage
Open a file using the File->Open menu, the toolbar button or drop a file onto the window. If nothing happens, the file is locked by another application.
The offset is the number of bytes into the file the cursor is. You can seek to a particular offset by typing in the new value and hitting enter.
The hex option changes the format of the offsets both the cursor and the labels down the left hand side. When switched on the format is hex, and you enter an offset in hex, otherwise enter the offset in decimal.
The little endian option changes the byte order of the information at the cursor (display on the right most part of the toolbar). Little endian is the x86 processor format, big endian is Apple/Motrola order.
Signed changes the info format to signed values.
Once you have edited the document you can save your changes if you need to. If you move the cursor far enough away from the edits then you will be asked to save your changes, this is because only part of the file is in memory at any given time. This is a side effect of the implementation I used to allow any size files.
Use the Tab key to swap focus between the hex and ascii pane. The pane with the focus has a slightly thicker cursor line.

VPNetMon 0.91 is developed as a perfect solution for you to keep track of your VPN connection in case every program at your computer is running unsecured with your normal IP address. But sometimes the VPN service isn't able to reconnect and applications might run for hours without VPN security.

VPNetMon monitors your VPN connection and simply closes the application of your choice when the VPN connection is down. If closing the application is not possible it will kill the application process the hard way.

Enhancements: Adds Windows Vista compatibility and now can monitor external applications.
