Gimp makes progress, but Krita and Darktable get it right.

GIMP 2.10.6 introduces vertical text layers and comes with improved performance. Recently, the GNOME foundation received a 400,000 $ donation and they sent a quarter of that money to GIMP. Hopefully this financial support will help to finally make GIMP useable in a productive environment. Currently, color management is still broken. But the space invasion project made the underlying General Graphical Library (GEGL) fully color-managed and the developers of GIMP try to make use of this and make GIMP fully color managed, too. This development takes place in the GIMP 2.99 development version (git master branch of GNOME/gimp). For the time being, stick to the second big open-source image manipulation software, Krita, whenever possible (the text tool needs to be overhauled). Krita 4.11 has support for Python 3 scripting, vector, filter, group, and file layers. You can nondestructively work on layers with masks. Krita supports full color management through LCMS for ICC and OpenColor IO for EXR and comes with a wide variety of icc working space profiles for every need, with a color space browser to visualise and explore them. HDR and scene-referred images and it has OCIO and OpenEXR support. For radiometrically correct processing of images in RAW or TIF format involving only level adjustment and cropping, Darktable is the software of choice.

Scalable knitting patterns with open source software: Textile design with Inkscape and GIMP.

I made a video tutorial that explains how to design knitting patterns that can be scaled to arbitrary size using the open source programs Inkscape v0.92 and  GIMP 2.10.10 . It may be especially interesting to the community of the All Yarns are Beautiful (AYAB) project . This page was moved to https://derandere.gitlab.io/scalable-knitting-patterns-inkscape .

Demonstration of the lab robot "PipetBot-A8" by DerAndere.

I am proudly presenting a working prototype of my pipetting robot "PipetBot-A8".  Of course it is an ongoing project and there are many things to improve, but the device is doing what I want and its precision is already quite good. Here is a link to the video . After I finally managed to fix most issues with my robot control software GGCGen, it is ready for testing. I uploaded an introductory video that showcases the Graphical G-code Generator . Visit the page "PipetBot-A8" on this blog for details. Brought to you by DerAndere.

Get rid of your kilos in less than 4 months?!

Are you worried about gaining some extra kilos during Christmas time? Then you may be pleased to read that your old kilograms will be gone in no time. In fact, exactly on 19th May 2019 all kilograms in the whole universe will be gone "PUFF"... and they will be replaced by brand new, much better kilograms! WOW!  That is because the 26th General Conference on Weights and Measures revised the International System of Units in order to derive all SI base units from natural constants. So the kilogram is no longer defined as the mass of the International Prototype Kilogram. The new definition of the kilogram is rather: The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1 , where the metre and the second are defined in terms of the speed of light and the caesium frequency .   I'm sure you lost at least two kilo
