Indian researchers at the Total Solar Eclipse 2024 in Dallas, Texas

A team of Indian researchers from ARIES (Aryabhatta Research Institute of Observational Sciences) traveled with scientific instruments to study the sun during the total solar eclipse at the Cotton Bowl Stadium in Dallas. The equipment used to capture scientific data during the eclipse was quite heavy, and I couldn't help but imagine the struggle that … Continue reading Indian researchers at the Total Solar Eclipse 2024 in Dallas, Texas →

Monitoring and managing Micronaut application

Managing and monitoring a microservices architecture is no brainer with the Micronaut framework. In my previous post, we implemented an API gateway to our reactive Maps service which used Micronaut's Consul integration for discovery and provided automatic client-side load balancing. In this post, let us look at implementing some of the monitoring capabilities to our … Continue reading Monitoring and managing Micronaut application →

Micronaut API gateway in action

In this post, I am going to show how we can implement a simple gateway service for the Maps microservice developed in the earlier post. Gateway microservice is another Micronaut service that consumes our Maps service and provides public API access for users, requests are routed using gateway which can be managed, monitored, secured and … Continue reading Micronaut API gateway in action →

Reactive microservices development with Micronaut

There is some fresh air in the microservice development stack for developers. Java developers usually look at Spring Boot which provides a platform for building production grade services that helps implement microservice architecture and targets Spring developers. There are couple new frameworks to look for that could shape up this landscape in the coming years. … Continue reading Reactive microservices development with Micronaut →

Must have Time and Size Log4J appender for your application

TimeAndSizeRollingAppender, a very handy Log4J appender that supports rolling log files by time and size. I haven't found one that meet my requirements in the built-in/extra appenders provided by log4j project. DailyRollingFileAppender is the closest appender I could live with, but there is no way to control size of the file when rolling, which is … Continue reading Must have Time and Size Log4J appender for your application →

Private interface methods in Java 9

Starting in JDK 9 build 54, compiler support for private interface methods have been resurrected. This was one feature that was planned for Java 8 and did not make the final cut. It is now part of JEP 213. The primary motivation for this proposal is to enable code sharing between non abstract methods in … Continue reading Private interface methods in Java 9 →
