These are programs I wrote for fun or as small exercises. Please feel free to download and use them. You can also download the source code for all of these programs and modify it any way you like (but please give credit where due). If you do anything neat with any of these, let me know!
Note: Some of these programs were previously released as shareware, and, in some cases, the documentation still indicates shareware status. However, I am no longer trying to sell these as shareware. Instead, the versions you see here are the complete ("registered") versions. On the other hand, I don't always have time to answer technical support questions related to these programs.
Useful Stuff

An
add-in for PowerPoint that allows you to easily insert LaTeX
equations into your presentations.
I wrote the original version of IguanaTex; it is currently maintained by Jonathan Le Roux, who has expanded it quite a bit. |

This is a small JavaScript program for translating WGS84 coordinates (longitude and latitude)
to Israel grid coordinates. Both the new ITM grid (רשת ישראל החדשה) and the old ICS grid (רשת ישראל הישנה)
are supported. Hebrew version also available.

A simple web-based editor for writing guitar tabs in the standard textual format.
Joint work with Naama Ben-Haim. See the
source on GitHub.

This website includes a friendly introduction to
blind minimax estimation, some examples, and a BME package for Matlab which
you can download and use.
The site and software were written by Guy Leibovitz and Asaf Elron, as their undergraduate project under my supervision. |

A program to tune your guitar. Connect
a microphone and strum a single note on your guitar, and the program will
tell you if you're sharp or flat. (Written as a birthday present for my
brother Rafi, who was learning to play.) Download executable
or source (MFC/Visual C++ 6). No
documentation, but quite straightforward to use.

This is a computer program for automatic song identification. The user hums
a few notes from a song; these are analyzed and searched for in a database.
This was the graduation project of my bachelor's degree at the Technion, and
was conducted under the supervision of Gal Ashour.

Game Solvers
A hobby of mine has been to competitively write solvers for puzzle games such as Sudoku and the like. Here are a few of them.
 |
A program for automatically solving Minesweeper riddles, in which you are
shown a subset of the Minesweeper field and need to figure out where all of the mines
are located..
|
 |
A program for automatically solving
Kakuro
(also known as Cross Sum) puzzles. No documentation, but you'll figure it
out if you know the puzzle. Solves most large puzzles (22x13) in a few
seconds. Requires
.NET
Framework 2.0. Download executable
(with example) or source
(Visual
C# 2005 Express).
|
 |
A program for automatically solving
Sudoku (a.k.a. Number Place) puzzles. Just fill in the numbers you know
and leave the others blank, and the program will solve the puzzle for you
in under a second. Download the software,
sample puzzles, and source
(MFC/Visual C++ 6).
|
 |
This program solves the
Paint
by Numbers (Pic-a-Pix) puzzle, in which the
horizontal and vertical lengths of pixel sequences are given, and the
object is to figure out the picture. No documentation, but if you know the
puzzle, you'll figure it out; just drag one of the enclosed text files
into the program and click Action>Solve. (boat.txt is a good starting
example; carriage.txt is a difficult one.) Download the software (with
sample puzzles) or source (MFC/Visual C++ 6).
|
 |
Python-based solver for the Katamino game.
|
 |
A Python solver for
Tantrix
puzzles. Runtime can be a bit slow for larger puzzles (more than about 15
pieces); I'm sure this can be optimized further. Output is written as an
SVG file: see
example output.
|
Very Old Stuff
I've been writing software for a long time and many of these are both ridiculously archaic and embarrassingly incompetent. I'm keeping them here solely for nostalgic reasons.
 |
Alarm clock program. Choose to play a wave
file or run an external program (e.g. Media Player) at a specified time.
The cool feature is the ability to slowly increase the computer's volume,
so you don't wake up with a start. This was actually my alarm clock in the college dorm; this was, of course, before smartphones. Download the executable
(with help file) or the source (MFC/Visual
C++ 6).
|
 |
C++ package for basic matrix/vector
operations, such as matrix ranking, inversion, determinants, etc. However,
this package probably does not house the most numerically stable
algorithms, as it was written primarily as an exercise. Download the
package source code (C++), with
documentation and demo program for solving linear equations.

 |
In this guessing game, the computer
asks a series of yes/no questions to figure out what concept you are
thinking of. The program learns new concepts if its guesses fail. Concepts
of different types can be programmed; for example, a sample question
database which can identify over 100 types of animals is included.
Download software (with help and animals
database) or source.
