BOILERPLATE : What does this mean in the computing context?

Well,this is going to be a short post about a general info of what Boiler plates means in the computing context.Recently I came across this term for the first time as I read this paper "SHOULD CODE BE LAW? SMART CONTRACTS, BLOCKCHAIN, AND BOILERPLATE" by Jeff Lingwall and Ramya Mogallapu. Then further exploring about this term simply refers to sections of code that have to be included in many places with little or no alteration. It is often used when referring to languages that are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs.

More simply  : Any routine contract document would invariably be similar for most of its part except for the names and date changes.This similar part is the Boilerplate meaning it’s the same for everyone who gets that contract, with only a few changes.

EMBARK BLOCKCHAIN FRAMEWORK : INSTALLATION Ubuntu 18.04 LTS

Embark is a framework that allows you to easily develop and deploy Decentralized Applications (DApps).A Decentralized Application is a serverless html5 application that uses one or more decentralized technologies.Embark currently integrates with EVM blockchains (Ethereum), Decentralized Storages (IPFS), and Decentralized communication platforms (Whisper and Orbit). Swarm is supported for deployment.This post gives the screen shots for installing a demo contract on EMBARK platform.Embark needs few per-requisites and tools installed including Node,Geth and IPFS.The complete list of history command as executed for getting EMBARK running is produced below :
