Live testing is to test software in real-world situations with real users instead of simulated data. This approach allows testers to check software quality in actual usage scenarios and real-world conditions. They do have their own risks to take into consideration, since we are interacting with real users and live systems here. In this article, we will explore the concept of live testing in-depth, and how you can better do live testing with the right tools and approach.

Ruby on Rails has changed how we build web applications. Early on, the framework came with some great features to help you get started and build robust applications. However, it can still be tricky to build and handle forms. Simple Form is a great option. Let's examine what Simple Form is, why we might need it, and some real use cases.

Data provenance is a method of creating a documented trail that accounts for data’s origin, creation, movement, and dissemination. It involves storing the ownership and process history of data objects to answer questions like, “When was data created?”, “Who created the data?” and “Why was it created? Data Provenance is vital in establishing data lineage, which is essential for validating, debugging, auditing, and evaluating data quality and determining data reliability.

Software developers have plenty to keep them awake at night. Their top concern is no longer how to express the latest algorithm in their favorite language (C, C++, Erlang, Java, etc.). Instead, it’s being replaced by artificial intelligence (AI). Here we take a look at the process for AI writing code and answer the question: Will AI replace programmers? Read along or jump ahead to the section that interests you the most.

Pagination means dividing a big chunk of data into smaller pages. It unlocks performance benefits for the backend, while also improving UX by sending manageable pieces of data to a client. In this article, we'll explore offset-based and cursor-based server-side pagination approaches, compare them, and implement cursor-based pagination in Node.js. Let's get started!

Ably’s LiveSync product is now available as a public alpha release. LiveSync allows you to automatically keep data in sync across servers and clients, in realtime. This is a hard distributed systems problem. In this post, we’re going to have a look at four existing solutions to realtime data synchronization, the different technical designs, and the tradeoffs they make.

In many industries (finance and healthcare, to name a couple), regulations require the use of multi-factor authentication (MFA) to protect access to sensitive data and transactions. Also, an important executive order was issued, aimed at improving the cybersecurity posture within the US government by requiring all federal agencies to adopt MFA systems. Regulations and standards like these will continue to spread over more industries and transaction types.
