When building an IoT-based service, we need to implement a messaging mechanism that transmits data collected by the IoT devices to a hub or a server. That mechanism is known as a messaging protocol. A messaging protocol is a set of rules and formats that are agreed upon among entities that want to communicate with […]

Many organizations implement a full-featured code search/intelligence tool — e.g., SourceGraph or Atlassian Fisheye — allowing engineers to search the enterprise code base. Other orgs just use the native search of the hosted version control system, such as GitHub‘s or GitLab‘s search. There are other commercial and open sources ways to search code. Most of […]

Ethereum has a well-known problem: transactions are slow, expensive, and don’t scale well. L2s (layer twos) are a new generation of blockchains built on top of Ethereum to solve this problem. Among these new layer two solutions, Linea, a zero-knowledge rollup (or zk rollup), is one of the most promising. In this article, we’ll look […]
I had a discussion with one of my then-manager-colleagues about ensuring the movement of a planned item even if the only available team member has no expertise to take it on. The simple answer is to get that team member to a starting point with the help of the experienced ones, through a non-heavy pair […]
1. Introduction In this tutorial, we will quickly explore some basic to high-level approaches for testing microservice applications built using Kafka. Also, we will learn about the advantages of the declarative way of testing Kafka applications over the traditional/existing way of testing. For everything explained here, we can find running code examples in the “Conclusion” section […]
With many microservices deployed across multicloud and hybrid infrastructure (cloud, containers, and VMs), the manageability of the network becomes challenging. The transactions among services happen on the public network, so the sensitivity of the matter increases magnitudinally with rising incidents of hacking and cyberattacks. Istio service mesh is becoming a center of app modernization for […]
What Is an Anti-Corruption Layer (ACL)? In the world of microservices architecture, communication between services is of utmost importance. However, with the increasing complexity of microservices, communication between them can become a challenge. That’s where the Anti-Corruption Layer (ACL) pattern comes into play. This pattern is designed to improve communication between microservices by establishing a […]
If you have an aversion to new frameworks, don’t even read this. For other kind readers, please note that here I’m going to present a proposal for an API for modeling database queries in a declarative style with strong Kotlin type checking primarily. Only some classes around entities are implemented; the database connection is missing […]
