Create a front-desk visitor log with Node.js

Developing the server-side code

In this article, you learn how to use the IBM Cloud to write a Node.js application for an organization’s front desk, which needs to log visitors in and out. Along the way you will learn how to use Node.js, the Express HTTP server library, and a Cloudant database. You will learn how to do this in the highly available IBM Cloud. This is a basic introduction to Node.js programming on the IBM Cloud platform.

Metaprogramming in Python

author photo

Just like metadata is data about data, metaprogramming is writing programs that manipulate programs. It’s a common perception that metaprograms are the programs that generate other programs. But the paradigm is even broader. All of the programs designed to read, analyze, transform, or modify themselves are examples of metaprogramming. Some examples include:

  • Domain-specific languages (DSLs)
  • Parsers
  • Interpreters
  • Compilers
  • Theorem provers
  • Term rewriters

This tutorial explores metaprogramming in Python. It refreshes your Python knowledge with a review of Python’s features so that you can better understand the concepts in this tutorial. It also explains how type in Python has more significance than just to return the class of an object. Then, it discusses ways of metaprogramming in Python and how metaprogramming can simplify certain tasks.

Blockchain essentials – Self paced course

Blockchain is an emerging technology that can radically improve banking, supply chain, and other transaction networks and can create new opportunities for innovation. Businesses contain many examples of networks of individuals and organizations that collaborate to create value and wealth. These networks work together in markets that exchange assets in the form of goods and services between the participants.

Blockchain technology provides the basis for a dynamic shared ledger that can be applied to save time when recording transactions between parties, remove costs associated with intermediaries, and reduce risks of fraud and tampering.

The video lectures and lab in this course help you learn about blockchain for business and explore key use cases that demonstrate how the technology adds value.

Note: This course does not cover cryptocurrencies, such as Bitcoin, in detail.

Use domain-driven design to architect your cloud apps


Domain-driven design (DDD) is a set of strategies and tools that can help you design systems and manage complexities. You can learn a lot more online about it than we can cover in one tutorial, so we won’t dive too deep into the theory and roots of DDD. Instead, we will focus on how it can be used to architect cloud applications—specifically how to integrate it into existing stacks, and especially how it can help you build powerful event-sourcing systems.

Create and deploy a Java Spring microservice to IBM Cloud

In this video:

Learn the quickest way to deploy a Spring-based Java microservice.


About this event

In this live coding event, Paul will demonstrate how to create and deploy a Spring-based microservice in less than 10 minutes. First he will build and run the service locally. Then he’ll deploy it to the cloud using automatically provisioned services. He will be using the IBM Cloud Developer Tools CLI to streamline the creation and deployment process.
