Simple PHP Hit Counter is a simple hit counter written in PHP and using SQLite as a database. It can be included in a page like an image, and the hits will be counted as the graphic is created. After that, the IP will be blocked for further counts (10 minutes by default). Administration (creation of counters, etc.) is done via a web frontend, which is password protected. There's also a log, a small statistics page and a calendar that shows the hits per day.
Fano is a fast and powerful encoder and soft-decision sequential decoder for K=32, rate 1/2 convolutional codes. The algorithm it uses is many times faster than the Viterbi algorithm. It also includes support routines to generate metric tables that are optimized for Gaussian noise with a specified Eb/N0 ratio, and a test driver that exercises the encoder/decoder routines and keeps statistics.
MIDI Class is a PHP Class for reading, writing, analyzing, modifying, creating, downloading, and playing (embedding) standard MIDI files (type 0 or 1). MIDI songs are internally represented as lists of tracks, where each track is a list of messages, and each message is a string. The message string format is the same as the one used by the command-line tools MF2T/T2MF, created by Piet van Oostrum. The class provides methods to generate and manipulate MIDI data and to import and export binary MIDI files (SMF, *.mid), text in the MF2T/T2MF format, and MIDI XML.
