Quarkus 2.7.1 Released - Why Quarkus?


Quarkus, the Java framework for microservices initially released by RedHat in March 2019, has reached version 2.7.1. But before looking at what's new, let's take a look at what Quarkus does differently and how it contributes to the current popularity of Java.


Describing Quakus as a "Java framework for microservices" isn't 100% accurate. Despite the fact that Quarkus was created with microservices in mind, you can also build monoliths with it. Also, while Java is the primary language, you can write Quarkus programs in Kotlin and Scala as well.


Quarkus, together with Micronaut and Helidon, is part of a new league of open-source frameworks that have sprung up in the last few years in order to boost the usage of Java in the microservices world. Java supremacy in this arena was under threat due to the bloat that existing frameworks were burdened with - hundreds of class files required, resolving dependencies at runtime, use of reflection, large memory footprint, extended warm up time. Spring and Jakarta EE were the typical perpetrators.


Spring of course is a monumental piece of technology - a versatile framework that does a lot under the covers to boost developer productivity. That magic comes with a drawback, however. The magic Spring pulls is happening at runtime, analyzing your code and the annotations, injecting beans, etc thus using a lot of runtime loading as well as reflection under the hood.

Open Source Is Not Just About Software

  It's about infrastructure as well, something that although not attracting the limelight, is as important as the open source software it hosts. Today the stewards of the largest open source registries in the world have issued an open letter demanding urgent reform in how open source infrastructure is funded, maintained, and operated.  https://www.i-programmer.info/news/136-open-source/18334-open-source-is-not-just-about-software.html

Europe Gets Its Own LLM

  EuroLLM is a fully open-sourced large language model made in Europe and built to support all twenty-four official EU languages. While several European states have separately produced their own LLMs, such as Greece's "Meltemi" or the recent offering from Switzerland "Apertus", there was no solution that catered for the languages of all 24 states belonging to the EU block. The time has come for this status to change with the appearance of EuroLLM, a foundational model that supports them all. https://www.i-programmer.info/news/105-artificial-intelligence/18448-europe-gets-its-own-llm.html

The PaSh Project gives your POSIX script superpowers by utilizing parallelization in order to speed up execution times.

The PaSh Project gives your POSIX script superpowers by utilizing parallelization in order to speed up execution times. This leads to faster results for data scientists,  engineers,  biologists,  economists,  administrators,  and programmers. I remember the time when the saying was "Learn Perl so you don't have to learn the Shell and its hundreds of utilities". Fast forward some decades and the use of shell scripts still has not been eradicated. On the contrary, their use has increased due to the rise of containers, VM's, administering the cloud, and Linux itself. This also serves as a lesson to those who are quick to denounce technologies as 'dead'. There's a time where a new use case revitalizes an old technology. So what is meant by "Unix philosophy"?  full article on i-programmer: https://www.i-programmer.info/news/90-tools/14990-the-pash-project-advancing-the-unix-philosophy-one-step-further.html
