• Online Spike sorting: Osort - an opensource implementation of my online spike sorting/unsupervised clustering algorithm (in matlab). Available together with example files, documentation and the original paper here.

• Implementing DFAs with Winner-take all networks: Matlab/Java package for automatically converting arbitrary deterministic state automatons to winner-take-all networks. Accompanies our recently published paper. Includes a tutorial.

• Neuralynx CSC and EV file reader (neurophysiology file formats) for matlab on unix: Port of Neuralynx CSC (continuous data traces) and EV (events) file reader for linux/matlab. These are matlab mex files, implemented in C++. Please note that the original version (windows, using MFC) code is owned by Neuralynx Inc.; I ported the existing code to make it run under unix (gcc). The latest version (see below) also compiles on Mac OS X.

  Original 32-bit Version (2004): download directly from neuralynx
  Updated version: 64-bit and 32-bit versions (Aug 2009). Compiles with latested g++/libc/matlab version 2008a on linux as well as Mac OS X (including matlab 2009, 64 Bit). Please read the README file for instructions!

Past software projects (not actively maintained, but still useful):

• ABI: Adaptive Building Intelligence. An opensource java framework for online learning from sparse events. Its usefulness is demonstrated by applying it to an intelligent building (integration with LON). The original ABI can be found here. New versions, originally based on ABI, can be found here.
• Java SCEP: A SCEP (Cisco Simple Certificate Enrollment Protocol) client, including proxy for PKCS#12 key requests so that browsers can use SCEP for key requests. A SCEP server can be found here. The JAVA SCEP client is available here.

Other (old) software stuff that might be of use:

• Lex File/Alice/Festival: Lex File (with C code) that redirects interactive output of alice (a AI chat bot) to festival for immediate speech output. This enables alice to give output over a speech synthesis system like festival is. chat.l
• Win32ASM: A task kill/list utility written in pure ASM for win32 (win32 console app). Directly uses the Win32 API by calling functions from kernel32.dll. Written in NASM syntax. Requires NASM (compiler) and ALINK (linker). killer.exe (only 4KB!) killer.asm kernel32Custom.lib

A completely retyped version in latex (courtesy of Akram S. Sadek, Caltech) of the classic Probabilistic logics and the synthesis of reliable organisms from unreliable components by J. von Neumann, originally published in C. E. Shannon and J. McCarthy (editors), Automata Studies, 1956. Also note the article "Parallel information and computation with restitution for noise-tolerant nanoscale logic networks" by Akram S Sadek et al 2004 Nanotechnology 15:192-210 for an application to new physical substractes of computation (link).
