Partsim online circuit simulator.

PartSim is a free and easy to use circuit simulator that runs in your web browser.
I create today my account to see how better is this online tool.
You can build, test and simulate your e with a SPICE Simulator, AC/DC/Transient Sims and Waveform Viewer.
The Arrow Integration lets the PartSim include an integrated Bill-Of-Materials manager that lets you assign Arrow Part Numbers to your models.
You can see many examples on the official website:

• Bipolar Differential Amplifier;
• Simple CMOS Inverter;
• OpAmp Transient Full-wave Rectifier with Smoothing;
• Capacitor;
• Passive Low Pass Filter;
• RC Charging Circuit;
• Differential Amplifier

You can see many video tutorials on the official website:

Firebase and Unity 3D.

Even is an old feature the Google team comes with this new option for the new developers and show how to use them.
The goal is to add Firebase to your Unity project.
The Google webpage tells us:
Power up your Unity games with our Firebase Unity SDKs. To show how easy it is to plug Firebase into your Unity project, we made a sample game, MechaHamster, that you can download from GitHub, the App Store, and the Google Play Store.
... and show a short video about how can be used to create a application named Mecha Hamster, see the GitHub webpage project:
You can import the project with GitHub commands:

https://github.com/google/mechahamster.git
...

The game is pretty funny, see the Youtube channel from Firebase:

Unity 3D : Fix error "Failed executing external process for 'Bake Runtime' job."

If you want to remove the error show on the Unity 3D console:
Failed executing external process for 'Bake Runtime' job.
... then go to Main Menu - Lightning - Settings and uncheck the Auto Generate checkbox.
See the screenshot shown below:

Unity 3D : Use Quick Fix on Visual Code for Unity and Linux.

Because I don't use Unity 3D with Linux and Visual Studio today I solve another issue for the development area.
This is the quick fix option for Visual Code that helps the user to add source code.
For example, you can add source code for the implement an abstract class PlayerBaseState:

using UnityEngine;

public abstract class PlayerBaseState 
{
    public abstract void EnterState(PlayerController_FSM player);
    public abstract void Update(PlayerController_FSM player);
    public abstract void OnCollisionEnter(PlayerController_FSM player);
}

Create a new C# script named PlayerIdleState. The script needs to be changed into this source code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerIdleState : PlayerBaseState
{
    
}

Select the PlayerIdleState and use these keys: Cmd or Ctrl and . (the point key) .
This will show a menu named Generate overrides... and help the developer to generate the new code:
The result is this source code with all new override for each of methods of PlayerBaseState class:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerIdleState : PlayerBaseState
{
    public override void EnterState(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }

    public override bool Equals(object obj)
    {
        return base.Equals(obj);
    }

    public override int GetHashCode()
    {
        return base.GetHashCode();
    }

    public override void OnCollisionEnter(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }

    public override string ToString()
    {
        return base.ToString();
    }

    public override void Update(PlayerController_FSM player)
    {
        throw new System.NotImplementedException();
    }
}

SpriteStack online tool for sprites with 3D features.

This is an awesome online tool to create sprites for your game named SpriteStack.
You can find this online tool on this web page.  
SpriteStack is a 3d pixel art editor based on the sprite stacking technique. Similar to voxels it's a fun and simple way to draw low-resolution 3d objects that can be later used in games or submitted to the online gallery.
The tool is easy to use and the output is good.
I use the free preview of Sprite Stack Studio but you can get one of the options to unlock all features from Steam or Itch.io website. If you want to have full online access to the editor and exporter at a low price then use the Patreon website with just 2$ per month.
I find a good tutorial on youtube but you can see the videos from help webpage:

Unity 3D : Setup Visual Code for Unity and Linux.

The tutorial for today will cover the settings of Visual Code and Unity into a Linux distro.
First, you need to install the Visual Code into your Linux distro.
You need to have the Unity 3D software working well into the Linux distro.
Open the Unity 3D software and create a new script using the main menu: Assets - Create - C# Script.
Open into Unity 3D from the main menu: Unity - preferences - External tools.
Select the Visual Studio Code like into the next image:

Double click on the newly created C# script.
This will open the Visual Studio Code and will ask you to install the C# feature using the Install button, see the next image:
 
This will install the C# extension for Visual Code.
The last step is the install of DotNet for Visual Code.
Use the button with the name Get the .Net Core SDK to install the Net CORE.
This will redirect to a webpage where you find the commands to install for your Linux distro.
After these steps, you can use Unity 3D software with Visual Code.

Unity 3D : Settings for Android build game.

If you try to set the Android SDK on Unity 3D using the Linux O.S. then you can have a problem.
After you set the name of the package and the default android settings you can use External Tool from menu Edit - Preferences to set paths for Android SDK, NDK, and more.
This is the path I used to build with Android:

• /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/OpenJDK
•  /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/SDK
• /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK
• /home/catalin/Unity/Hub/Editor/2019.3.5f1/Editor/Data/PlaybackEngines/AndroidPlayer/Tools/gradle

You can see the android SDK, NDK and Gradle is set on the Hub Editor This is my External Tools configuration for that build game:

Unity 3D : The new learning area ...

The Unity 3D game engine comes with significant improvements in the learning area.
If you know nothing about Unity Editor and C # then this area has a simple and efficient introduction for new developers of this game engine.
For example , see the Creator Kit: Beginner Code.
You can start with John Lemon's Haunted Jaunt: 3D Beginner or with the Ruby's Adventure: 2D Beginner.
I am starting to see how deep and good these tutorials are and for me it was quick to follow them and use them.
This is an more advance learn step from Unity 3D using the Creator Kit: Beginner Code.

Another form of art: Deep Dream Generator tool.

Deep Style. The technique is a much more advanced version of the original Deep Dream approach. It is capable of using its own knowledge to interpret a ... We are just a small team of enthusiasts who are trying to build something cool. Our goal is to make the latest developments in AI widely and freely accessible.
This online tool lets you use the power of the computer to lineup the images into a new form of art.

Contest from HUION.

Another contest from HUION with the theme named Distant Worlds in 2020.
The HUION team comes with this intro:

We all love good novels and movies. Those wonderful stories show us possibilities that happen far in the future or adventures happen in distant worlds. But sometimes the stories set in a certain year. There was a space odyssey happened in 2001, Harry Porter sent little Albus to school in 2017, Roy Batty the android passed away in 2019… And now the Year 2020 is here. What will happen in 2020, what will the world looks like in 2020, join in #Huion2020 drawing challenge, draw your imagination down!
