Reducing Verification Lead Time by 50% by Lowering Defect Slippage and Applying AI/ML Techniques
Can we increase our flexibility? Can we increase our test coverage? Can we increase our efficiency? And is it possible to reduce our verification lead-time by 50%? One company challenged itself with these questions. This article explores two important “‘pillars”’ of their testing strategy: shifting left and using state-of-the-art techniques to support verification activities.

Debugging Production: eBPF Chaos
This article shares insights into learning eBPF as a new cloud-native technology which aims to improve Observability and Security workflows. You’ll learn how chaos engineering can help, and get an insight into eBPF based observability and security use cases. Breaking them in a professional way also inspires new ideas for chaos engineering itself.

Debugging Go Code: Using pprof and trace to Diagnose and Fix Performance Issues
In this article, we will look at how to identify and fix performance issues in Go programs using the pprof and trace packages. We will begin by covering the fundamentals of the tools, then delving into practical examples of how to use them. By the end of this article, you will have a solid understanding of how to use these powerful tools to improve the performance of your Go applications.

Thinking Deductively to Understand Complex Software Systems
Thinking differently can allow us to approach problems in new ways. With testing, approaching the problem with a negative approach can lead to more thorough test cases.

Debugging outside Your Comfort Zone: Diving beneath a Trusted Abstraction
This article takes a deep dive through a complex outage in the main database cluster of a payments company. We’ll focus on the aftermath of the incident - the process of understanding what went wrong, recreating the outage in a test cluster, and coming up with a way to stop it from happening again, and dive deep into the internals of Postgres, and learn about how it stores data on disk.

If You Want to Deliver Fast, Your Tests Have the Last Word
A good testing strategy is critical for safe code changes, fast delivery, reduced MTTR, and improved developer experience. Shifting the concept of “unit” can reduce the time needed for changes.

Respect. Support. Connect. The Manager’s Role in Building a Great Remote Team
As managers, we face challenges in terms of needs, accessibility, gender, nationalities, and other conditions that influence our teams and working environments. We cannot build projects based on Excel sheets only, not considering peoples’ preferences and options for personal growth. We need to see real people – even if we meet them in a virtual working environment only.

The Process of Creating Decentralized Apps (dApps)
A decentralized application has a different architectural approach; they are working on distributed ledger technology called blockchain, where there is no central point of failure nor third parties involved. A revolutionary and attractive technology for new opportunities. This article covers creating such applications and why they are needed, as well as challenges during implementation.

The Unit in Unit Testing
In this article, we will focus on how developers should consider using fake objects instead of mock objects, as fake objects offer similar isolation benefits while driving high confidence, clear documentation, and loose coupling between implementation and test code.
