Social media image sizes in development.

A good approach to social media development is the study of international web sites and the way they are built.
Today I will present you a collection of information that will complete the design palette and the graphics: Social media image sizes.
Here's how these are shown in the following tables:

My freelancer offer ...

Now I'm working with an project , but I can make my free time for smaller or longer projects ...
I can come up with a $ 5 / day offer for graphics and drawing production:

• the formats obtained with the free software;
• Blender 3D versions 2.79 and 2.8 for 3D graphics;
• Inkscape, Gimp, and Krita for 2D graphics;

Note: for painting and drawing other than, the $ 5 / day offer, the materials used (color watercolor or acrylic, quality paper or canvas, frames) for the final product will also be calculated.

Krita 4.2.2 : Programming with python.

The Krita application is written in C++ using an application framework called Qt5.
You can use python to create scripts for Krita software.
You can use Tools - Script - Scripter from the main menu to write your python script.
I don't use often this python module, but today I created this script.
The script creates a new document with size 512x512 named Python test document.
After that create a duplicate of the layer named Background.
The new layer is named the new Layer duplicate.

from krita import *
from  krita import Krita

print(dir(krita))
print(help(Krita))

d = Krita.instance().createDocument(512, 512, "Python test document", "RGBA", "U8", "", 120.0)
Krita.instance().activeWindow().addView(d)

print(dir(d))
print(Krita.instance().filters())

node_name = 'Background'
node = d.nodeByName(node_name)
print(node.name())
print(dir(node))

d_n = node.duplicate()
print(dir(d_n))

d_n.setName("new Layer duplicate")
print(d_n.name())
root_node = d.rootNode()
print(help(root_node.addChildNode))
root_node.addChildNode(d_n, node)

Blender 3D : Create a Printed Circuit Board with Blender 2.80 released Candidate

This is a simple video tutorial about how to create a Printed Circuit Board with Blender 2.80 released Candidate:

News : Blender 2.80 Release Countdown.

The development team comes tells us about the new Blender 2.80 Release Candidate on the official webpage:
A Release Candidate is the final step before the release. Blender has been built and packaged just like the official release, and is available for a short period of testing. Please download it and give it a good try. If things go as expected, the final release will be one week after.
The Blender 3D team want to test it and report any issue:
The massive Blender 2.80 update is around the corner! Download and test this build and report any issue on developer.blender.org
After download you can see a message about supporting the Blender software: Thank you for downloading Blender! Next step: Support Blender Development Join the new Development Fund for only $6 / month and ensure the future of Blender.
I test it with the last blender file I worked ( a raspberry work, see http://festila-george-catalin.daportfolio.com).
This release works great.
The BlenderDiplom youtube channel comes with a video introduction about this new release:

News : NeoAxis Engine 2019.2.4 Released.

They come with a roadmap on the official website to see how the development works.
I want to see tutorials and video tutorial to follow my issues with C# but I expected to see it in the future.

Krita 4.2.2 : Install the G'MIC on Krita software.

The G'MIC tool can be installed on Krita version 4.2.2 and older versions.
This tool is an opensource filter framework.
The G'MIC is open-source software distributed under the CeCILL free software licenses (LGPL-like and/or GPL-compatible).
You can download it from here.
Download it, unzip and place it somewhere you can find it.
Open the Krita software and use Settings - Configure Krita - G’Mic plugin and set G’MIC to the file path there.
The official YouTube channel has many video tutorials with this tool and GIMP software.
This is an old video tutorial with one old version of Krita:

Google hidden tools and features.

This tutorial is about Google hidden tools and features.
Many of the tools and online games are hidden in the Google search area.
Open your browser and search this: 10 value spinner.
This will show a spinner and you can test it.
You can find into the bottom of this online tool many features: Flip a coin, Color picker, Rol a die, Metronome, Meditate and Calculator.
This is a screenshot with the 10 values Spinner tool.

The Kerkythea software.

The development team of the Kerkythea software comes with this intro:
Kerkythea is a freeware software that can produce high quality renders without spending a cent on software licensing. Kerkythea is using physically accurate materials and lights, aiming for the best quality rendering in the most efficient timeframe, with target to simplify the task of quality rendering by providing the necessary tools to automate scene setup, such as staging using the GL real-time viewer, material editor, general/render settings, editors, etc., under a common interface
This software is available for all major platforms Windows, Linux, and MacOSX.
The software supports the following 3D File Formats: 3DS, OBJ, XML (Native KT format) and KZX (Zipped KT XML format).
You can find many videos about Kerkythea created by Hipolito Rodrigues.
You can download it from the official webpage.
The software is easy to use.
Open your model with File - Open and use Render - Start to render the output.
The final Rendered Image can change it with some colors settings: Tone Map, Exposure, Gamma, Dark, and Bright.
The Sun & Sky Wizard tool lets you fix it by Location, Zone, Year, Month, Day and Hour, Minute, Second.
The last setting of this tool is Sky Type.
The model object can be translated and rotated it.
Each object can have materials with many basic features and can be imported just like mat.zip type file.
I found some bugs:

1. the texture preview did not follow the changes by size;
2. the texture working area is hard to use;
3. the tools for animation and brush is unfinished;
4. the render network tool is unfinished;

In conclusion, this software is 88% completed by the development team.
