The missing package manager for macOS (or Linux). The script explains what it will do and then pauses before it does it. Homebrew installs the stuff you need that Apple (or your Linux system) didn’t. Homebrew installs packages to their own directory and then symlinks their files into /usr/local (on macOS Intel). Homebrew won’t install files outside its prefix and you can place a Homebrew installation wherever you like. Trivially create your own Homebrew packages. It’s all Git and Ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates. Homebrew formulae are simple Ruby scripts. Homebrew complements macOS (or your Linux system). Install your RubyGems with gem and their dependencies with brew. Homebrew Cask installs macOS apps, fonts and plugins and other non-open source software. Making a cask is as simple as creating a formula.

Nix is a tool that takes a unique approach to package management and system configuration. Learn how to make reproducible, declarative, and reliable systems. Nix builds packages in isolation from each other. This ensures that they are reproducible and don't have undeclared dependencies, so if a package works on one machine, it will also work on another. Nix makes it trivial to share development and build environments for your projects, regardless of what programming languages and tools you’re using. Nix ensures that installing or upgrading one package cannot break other packages. It allows you to roll back to previous versions and ensures that no package is in an inconsistent state during an upgrade. Nix is a purely functional package manager. This means that it treats packages like values in purely functional programming languages such as Haskell, they are built by functions that don’t have side effects, and they never change after they have been built.

Every expression in Haskell has a type that is determined at compile time. All the types composed together by function application have to match up. If they don't, the program will be rejected by the compiler. Types become not only a form of guarantee, but a language for expressing the construction of programs. Every function in Haskell is a function in the mathematical sense (i.e., "pure"). Even side-effecting IO operations are but a description of what to do, produced by pure code. There are no statements or instructions, only expressions that cannot mutate variables (local or global) nor access state like time or random numbers. You don't have to explicitly write out every type in a Haskell program. Types will be inferred by unifying every type bidirectionally. However, you can write out types if you choose, or ask the compiler to write them for you for handy documentation.

Etheno is an Ethereum-testing, JSON RPC multiplexer, analysis tool wrapper, and test integration tool. It eliminates the complexity of setting up analysis tools like Echidna on large, multi-contract projects. If you are a smart contract developer, you should use Etheno to test your contracts. If you are an Ethereum client developer, you should use Etheno to perform differential testing on your implementation. Etheno runs a JSON RPC server that can multiplex calls to one or more clients. API for filtering and modifying JSON RPC calls. Enables differential testing by sending JSON RPC sequences to multiple Ethereum clients. Deploy to and interact with multiple networks at the same time. Integration with test frameworks like Ganache and Truffle. Run a local test network with a single command. Use our prebuilt Docker container to quickly install and try Etheno. Etheno can be used in many different ways and therefore, has numerous command-line argument combinations.

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.

Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum. As a relatively young language, Solidity is advancing at a rapid speed. We aim for a regular (non-breaking) release every month, with approximately one breaking release per year. You can follow the implementation status of new features in the Solidity Github project. You can see the upcoming changes for the next breaking release by switching from the default branch (`develop`) to the `breaking branch`. You can actively shape Solidity by providing your input and participating in the language design.

Ethereum is the community-run technology powering the cryptocurrency, ether (ETH) and thousands of decentralized applications. Ethereum is a technology that's home to digital money, global payments, and applications. The community has built a booming digital economy, bold new ways for creators to earn online, and so much more. It's open to everyone, wherever you are in the world – all you need is the internet. Today, billions of people can’t open bank accounts, others have their payments blocked. Ethereum's decentralized finance (DeFi) system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world. Today, we gain access to 'free' internet services by giving up control of our personal data. Ethereum services are open by default – you just need a wallet. Stake your ETH to become an Ethereum validator.
