How to switch between Solidity version to Latest version

solc-select is a tool to switch between Solidity compiler versions. It is easy to install, learn and use. I recommend you put this into your tool box.

A tool to quickly switch between Solidity compiler versions.

The tool is split into two CLI utilities:

  • solc-select: manages installing and setting different solc compiler versions
  • solc: wrapper around solc which picks the right version according to what was set via solc-select

The solc binaries are downloaded from https://binaries.soliditylang.org/ which contains official artifacts for many historial and modern solc versions for Linux and macOS.

The downloaded binaries are stored in ~/.solc-select/artifacts/.

Quickstart

pip3 install solc-select

Usage

The global version of solc can be set with the solc-select use <version> command:

$ solc --version
solc, the solidity compiler commandline interface
Version: 0.5.2+commit.1df8f40c.Linux.g++
$ solc-select use 0.4.24
Switched global version to 0.4.24
$ solc --version
solc, the solidity compiler commandline interface
Version: 0.4.24+commit.e67f0147.Linux.g++

Use SOLC_VERSION environment variable to override the global version:

$ solc --version
solc, the solidity compiler commandline interface
Version: 0.4.24+commit.e67f0147.Linux.g++
$ SOLC_VERSION=0.5.2 solc --version
solc, the solidity compiler commandline interface
Version: 0.5.2+commit.1df8f40c.Linux.g++

You can list all available versions with solc-select install:

$ solc-select install
Available versions to install:
0.3.6
0.4.0
...
0.8.0
0.8.1

And install the one you need with with solc-select install <version>:

$ solc-select install 0.8.1
Installing '0.8.1'...
Version '0.8.1' installed.

Display the currently installed versions:

$ solc-select versions
0.8.0
0.4.2 (current, set by /Users/artur/.solc-select/global-version)

Solidity Guide For Beginners

Ethereum is known for its wide use in blockchain programming. Especially Solidity is used to write most of the blockchain applications known for today. Here, I’ll help you to learn solidity effortlessly.

1-Learn JavaScript

Image for post

Because you interact with the internet and the ethereum nodes at the same time, learning JavaScript becomes necessary to understand the data structures of solidity. Even more, ethereum nodes interact with nodeJS. Furthermore, solidity is written in JavaScript and it requires a basic understanding of JavaScript to work with the ethereum environment.

2-Look for courses (online/offline)

When I started learning solidity, my first course was face to face offered free because of my club’s connections. But I never stopped and decided to go further by purchasing a udemy course and looking for high-quality YouTube courses, you can level up your solidity skills by practicing. About offline courses, they can be really expensive for you to afford and online courses can allow you to look at the videos and ask questions lifetime.

3-Take notes and practice

Mentioned in my previous posts, taking notes by hand allows you not to forget easily when not practicing for a very long time. Even more, remembering the data structures can help you analyzing the codes even with the hugest projects imaginable. I managed to find most of the mistakes in my acceleration project in ethereum despite I was a beginner.

4-Setting up a text editor (optional)

You don’t have to if you prefer using remix IDE for projects. But you might need to consider certain text editors for the best results in programming on ethereum. But, they require you to download certain packages before starting to write your code on these text editors to compile solidity code on your computer.

High Efficiency Municipal Solid Waste Gasifier – Chanderpur Group

Gasification processes generally involve the reaction of carbonaceous feedstock with an oxygen-containing reagent. The gasification of municipal solid waste is done with the help of a municipal solid waste gasifier. The MSW has grown substantially during the last decade.

Inside MoveNet, Google’s Latest Pose Detection Model

Ahead of Google I/O, Google Research launched a new pose detection model in TensorFlow.js called MoveNet. This ultra-fast and accurate model can detect 17 key points in the human body. MoveNet is currently available on TF Hub with two variants — Lightning and Thunder.

While Lightning is intended for latency-critical applications, Thunder is for applications that call for higher accuracy. Both models claim to run faster than real-time (30+ frames per second (FPS)) on most personal computers, laptops and phones.

The model can be launched in the browser using TensorFlow.js architecture with no server calls needed after the initial page load or external packages. The live demo version is available here.

Currently, the MoveNet model works for the individual in the camera field-of-view. But, soon, Google Research looks to extend the MoveNet model to the multi-person domain so that developers can support applications with multiple people.

Build Tool for Android Applications

In this article, we’ll learn about Android Gradle plugin. We’ll see what what is Gradle in Android Studio and why it is necessary.
What is Android Gradle?
Gradle is actually an open-source build system. It is a tool that automates building, deployment, etc of a project. This tool is often used for Java Virtual Machine languages such as Java, Scala or Groovy. It is configured to do various tasks like testing, running, creation of documents, etc. Its strength is the flexibility that it provides to the developer.

For example, consider the task of copying a file from one directory to another. This task can be performed by Gradle build script even before the actual build process will happen.
