Another Dopey Calculator

Today's feature

Another dopey calculator

First a bit of news re. the lq libs and mc2. (mc2 is the makefile creator developed here at this blog.)

The latest version of mc2 is undergoing testing and with any luck will include a SNAZZY set of graphics routines. The uitool is very nice for quickly writing moc files ui headers, etc. Currently some of the built-ins are a bit clunky, but they are effective and easy to use, such as the...

Note: This blog entry will to go away soon. Another version is in the works.

KDE's 'kompare' is an excellent utility for viewing changes.

So for now, since this is a little buggy (not serious but needs tweeking), consider...

Today's Features

Simple program to add two pixels clamping each byte to 0xFF, but adding all four bytes in parallel for speed. There are no branches in the algorithm.
Another simple program to mix two colors defining a gradient using a fraction from 0 to 1. We compare floating point to fixed point math versions.

Surprisingly, the long version compiles about the same code as the short one with...

[UPDATE: (2013-06-10) The uitool link has been updated below. Better version, tested, has no mc2 lib deps.]

A ui tool for creating code skeletons.
A cool Sudoku puzzle solver (with save/restore file funcs).
A qt graphics lib with mc2-generated makefiles (qwt).
Notes about why mc2 kicks &ss.
Notes about kregeditor.
And the make-based installer fixups for root system installations.
