Simply Powerful ToolKit in short SPTK is a powerful widget toolkit based on the Fast and Light ToolKit (FLTK).
The goal of this library is to create the easy-to-use, compact and effective library of controls to extend the abilities of FLTK library.
It is geared for business-style application development with database support (ODBC). All the widgets support database connectivity. A special CDialog class makes editing database records very easy. Every widget can be connected to the field, and CDialog can be connected to the database table.
Most of the controls are database-bound. If you place them on the CDialog-derived window they can load and save information from/to database.
This is the first release version of my controls(widgets) library that was designed to work with FLTK. Im using it for about a year in the production project.
Enhancements:
- Fixed a bug in CField::asString() that cause returning an empty string for some non-empty fields.
- Added couple of small fixes for better error hanling in CRegistry.

cnslock is a dock application (dockapp) which provides a visual indication of the states of the three "lock" buttons (caps, num, and scroll).

cnslock was written so that I could see the state of those keys as I have a wireless keyboard with no leds on it.

Usage:

Simply launch:

cnslock

If you have problems running it under a different window manager, such as fvwm or enlightenment, there is a command line argument that may help:

cnslock -w

Shrew Proxy/Filter is a tiny proxy built on WEBricks HTTPProxyServer, extended for both URL and content filtering. Shrew Proxy/Filter is designed to be small, simple to configure, and easy to install.

It is extremely small, lightweight, and works quite well. All blacklists (both URL and content) are plain text, so most published lists can be simply dropped in and used.
