Published on January 11, 2016 in Quat, Release

Quat screenshot

Quat is a quaternion fractal generator, I found ca. 15 years ago on the interweb. It produces beautiful 3D fractals and still works flawlessly. I downloaded the sourcecode for v1.2 from Uni Stuttgart and polished the deployment for Mac, Windows and Linux, which is available on my github.

Binaries for Quat 1.3 can downloaded here for Mac, Linux, Windows.

CopyMove2 0.6.0 Release

For some time now I had plans to rewrite copymove, a command line tool/GIMP plugin, which is able to detect image forgery from the clone tool, means it detects areas with similar patterns in an image.

As usually with side projects the rewrite idled for some time and was reignited by an email of a reporter, who actually used that tool in his profession, though the old copymove couldn’t detect an obvious tampering in his sample image. This was very motivational, and I continued writing on CopyMove2 with his sample as reference.

For some time I released some internal versions for the reporter and myself, fixed the worst bugs, and added a nice GUI with Qt. The current state can be downloaded here for Mac, Linux, Windows.

Parsing __DATE__, __TIME__ with C++11

Published on February 21, 2015 in Tech

This is how you parse the __DATE__ and __TIME__ preprocessor macros into a time_t variable and back to a formatted std::string to use in your program. This sample was tested with clang 3.4 and g++ 4.9.

The output is:
Feb 21 2015 16:04:27
Feb 21 2015 16:04:27

Notes: The cppsh interpreter can be downloaded here.

Black Silk 0.4.0 Release

Published on July 26, 2014 in Black Silk, Release

We proudly present the latest Black Silk Release

<<< 0.4.0 >>>

You can download the latest version here.

The latest release includes a reworked mixer filter which is able to filter highlights and shadows separately. Since this concept is new and possibly needs some time getting used to, we used the same user interface as the split tone filter to make the handling as easy as possible:

blacksilk_040

As you can see in the sample image, the new mixer is able to increase the overall contrast and to emphasize the textures and so to give the result more ‘character’:

Haus_Dual_Mixer

What’s new:

  • brand new mixer concept
  • updated splittone presets
  • added lock to splittone
  • preset import for pre 0.4.0 versions

Business plan with LaTeX

Published on April 27, 2014 in Tech, Utilities

LaTeX logo
Yesterday I wrote our business plan with LaTeX. Since this looks really good, I thought it would be nice to share a template in case you want a LaTeX business plan, too.
Download all files here:
https://github.com/elsamuko/business_plan_template

This is how it looks like: business_plan_template.pdf

Notes:

  • The template was tested with kile on Linux
  • The template is configured for English output, but you may change this by modifying the line “\usepackage[english]{babel}”

Happy LaTeXing!
