A set of Unix command line tools for quick and convenient batch processing of tabular text files (a.k.a., tab-delimited, csv, or flat file format) with a header line. Provides delimiter and compression detection, column reference by name. * tblmap: per-line ("map") computation: derive columns through an expression, delete, reorder, filter rows. * tblred: compute ("reduce") aggregations (e.g., sum, average) over groups defined by key columns. * tbldesc: Summarize columns in file (e.g., proportion of character/numeric values, min/mean/median/max, missing values, correlation with a target column). * tbljoin: Relational join without the need of pre-sorting and column matching. * ...

QChartist is an open source technical analysis software. Its purpose is to provide a complete set of tools to perform technical analysis on charts and data. It helps to make forecasts mainly for markets but can also be used for weather or any quantifiable data. The program is flexible and its functionalities can be easily extended. You can draw geometrical shapes on your charts or plot programmable indicators from your data. It is also possible to filter or merge data. I got a little inspired from MT4 allowing a fairly easy portability of programmed indicators from MT4 to QChartist. It is now faster and much more professional thanks to the use of a C++ layer (used mostly for calculations) over the standard Basic layer (used mostly for the GUI interface). You can use astro indicators and functions from a library for astronomical calculations. You can get realtime quotations thanks to perl scripts.

ZET-CSV is the C++ library for csv format. ZET-CSV uses STL library. Interface CSV container similar to the interface std::vector. You can use ZET-CSV (not as the library) with your code by rewriting the Makefile.

dhcp-gen is a perl script that was written by me and Trond Erik Dalho to simplify editing dhcpd.conf for adding static ip to computers and equipment on our school. It also made it easier to do manage the network by limiting some computers access to the local network only. Creating closed networks. And it also worked as a database over all our computers and equipment, making it easier to keep track of everything. All information about equipment is stored inside csv files which are comma separated.
