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 6.62607015×10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅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 kilos while recalculating …

GGCGen - Graphical G-code Generator for robot control

GGCGen - Graphical G-code Generator version 0.0.4
GGCGen - the Graphical G-code Generator and lab robot control software comes with an intuitive graphical user interface (GUI) for automatic creation of G-code. With the newest version 0.0.4, the program has made significant progress. Although still in development status, this open source software can be helpful to hackers / makers and users of DIY lab robots / liquid handling robots / pipetting robots like the PipetBot-A8 by DerAndere. GGCGen is well customizable and features smart positioning and tool change with one mouse click.

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 …

DerAndere goes Gitlab

Hey folks, 
In order to make my blog more readable and at the same time make the source code more accessible to developers and profit from version control, I removed a lot of raw-code from the pages of this blog and made the step to use public repositories on I am currently maintaining two Gitlab groups: and I also changed some of the used libraries, so most of my projects on Gitlab are now open source under the terms of the permissive MIT License!

Event: Parklichter 2018 in Bad Oeynhausen

[Werbung ohne Auftrag / unpaid advertisement]

Am 3.8.2018-5.8.2018 fand in Bad Oeynhausen das Event "Parklichter 2018" statt. Dieses Jahr war nicht mein erster Besuch dieser Veranstaltung. Ich wurde spontan von einer ehemaligen Kommilitonin dazugeholt. Ein gelungener Tag inclusive gemeinsamem Freibad-Besuch und Abendessen.

Event: Summer Soundz Kesselbrink 2018 in Bielefeld

Am 1.8.2018 fand in Bielefeld das Event "Summer Soundz Kesselbrink" 2018 statt. Ein Konzert mit Hey Miracle, einer Alternative Rockband aus der Region (Siehe Band-Profil auf Facebook und Soundcloud. Das Wetter war perfekt, um sich ein paar der dort angebotenen Kaltgetränke zu genehmigen und so verabredete ich mich mit einigen meiner  meiner Kollegen aus der Abteilung ab 19 Uhr zum chillen auf dem Kesselbrink. Klasse! 

Die Nacht der Klänge 2018 an der Universität Bielefeld. Am 20. Juli 2018.

Die Nacht der Klänge an der Universität Bielefeld ist jedes Jahr wieder eine  schöne Veranstaltung. Dieses Jahr hat unter Anderem das NÉ-K Trio (siehe auch Facebook-Profil und Soundcloud-Profil) mit gefühlvollen, jazzigen Klängen verzaubert:

AYAB shield - self soldered circuit board for a computer-controlled knitting machine

[Werbung ohne Auftrag / unpaid advertisement] 

Proudly presenting my first soldering job:
A printed circuit board for hacking a brother KH 910 knitting machine. The self-soldering kit of the so-called AYAB Arduino shield from the All Yarns Are Beautiful project of the Chaos Computer Club Munich enables control from a personal computer via USB. The AYAB shield sits on top of an Arduino Uno-compatible development board featuring an ATmega328PU microcontroller by Microchip Technology Inc. (formerly Atmel). The AYAB software for controlling knitting machines can be downloaded from the project's homepage.
I tested all connections with a multimeter and compared the result with the circuit diagram. And -believe it or not- it works! Stay tuned for updates on how it works in practice. Here is a photography of my little baby:

Gimp 2.10.0 released. The open-source competitor of Adobe Photoshop

Finally, the GNU Image Manipulating Program (GIMP) 2.10.0 has been released. The open source software GIMP can now be considered for productive work and makes professional image manipulation available for everyone. It supports high bit depth (up to 32 bit precision) and color management. Most importantly, GIMP now gives access to radiometrically correct adjustment of contrast / levels / curves, color mixing and blending (these operations have to be performed in a linear working space, i.e. in a color working space which has a tone reproduction curve with a gamma of 1.0 at all densities). GIMP is cross-platform software which means it is available for Microsoft Windows, Linux and Apple iOS. In my oppinion, this achievement is worth a donation to the developers by every user of GIMP. GIMP can now be regarded as a serious competitor for Adobe Photoshop.

Zyn-Fusion open-source synthesizer

Great news: The source-code for the synthesizer Zyn-Fusion was published. Now it can be built from source as explained on my blog on the page "music". Zyn-Fusion is the latest version of the powerful synthesizer ZynAddSubFX with the modernized graphical user interface "Fusion". It works as a stand-alone as well as a VST-plug-in.

GIMP 2.10 Release candidate 1 available

Finally, the GNU Image Manipulating Program (GIMP) 2.10 release candidate 1 is available for Linux as well as for the 64 bit version of Microsoft Windows. It is the first time, the open source software GIMP can be used for serious, professional image manipulation. It supports high bit depth (up to 32 bit precision) and color management. Most importantly, this is the first time GIMP gives access to radiometrically correct adjustment of contrast / levels / curves, color mixing and blending (these operations have to be performed in a linear working space, i.e. in a color working space which has a tone reproduction curve with a gamma of 1.0 at all densities). Only few problems remain to be solved, before GIMP 2.10 can be officially released as stable.

Event: Licht-sicht Projektions-Biennale in Bad Rothenfelde

Heute bin ich mit meiner Partnerin und ihrem Vater zum 10-jährigen Jubiläum der Licht-Sicht Projektions-Biennale (Bad Rothenfelde, bis 28.01.2018) gefahren, nachdem gestern aufgrund einer defekten Anlasser-Sicherung meine erste Fahrt mit dem elterlichen Campingauto bereits vor der Haustür endete. Währenddessen ist IT! weiter im Aufbau: Seit heute gibt es auf der Seite "Photography" meines Blogs eine Einführung in die Prozessierung von Rohbildern mit dem open source Programm darktable zu sehen.

Frohes neues Jahr 2018

Mittlerweile sind schon einige Abschnitte auf den Seiten "Programming" und "Music" meines blogs fertig. Viel spaß beim vorbeischauen wünscht DerAndere!

Happy new year!
