Error spawning cmd.exe
I got error message Error spawning cmd.exeduring compiling of Blender sources. The cause was in system PATH environment variable. Some buggy software I had installed and uninstalled before erased all contents of PATH. So I found out that Visual Studio 2008 has missing paths to %SystemRoot%\system32; %SystemRoot%; %SystemRoot%\System32\Wbem;A added it and the problem gone.

Overview of open-source node-based video editors (composers)
Synapse Compositor Seems unsupported for a long time Very raw Blender Good stuff, but it is designed originally for 3D modeling. Video editing is performed in composing mode. Rendering is veeery sloooowww. Open source. Available for linux and windows. Source code
Image resize in Nuke
So here we have two filters: Crop Reformat To cut a part from an image we use Crop. It also has option “reformat”. Reformat cuts also borders behind area. If “Reformat” is disabled, black borders remain after crop.

Conda cheat sheet
I usually prefer to keep (ana)conda deactivate in my system by default. One can chose such and option during conda installation. In order to activate base conda environment I run: source ~/anaconda3/etc/profile.d/conda.sh or source ~/miniconda3/etc/profile.d/conda.sh

Blinking multiple LEDs with Arduino (ATMega328p) and PCA9685
Arduino (ATMega328p) boards can be used to control multiple LEDs. To simplify the management of the pulse width modulation and use only a couple of arduino's pins for many LEDs I used PCA9685 controller. PCA9685 is connected to Arduino using I2C interface that requires only two data pins. .. image:: /media/2019-12-blinking-multiple-leds-with-arduino-atmega328p-and-pca9685/sketch_bb.png :width: 600px :alt: breadboard Blinking multiple LEDs with Arduino (ATMega328p) and PCA9685 .. image:: /media/2019-12-blinking-multiple-leds-with-arduino-atmega328p-and-pca9685/sketch_schem.png :width: 600px :alt: schema Blinking multiple LEDs with Arduino (ATMega328p) and PCA9685 ....
