Playing with NVIDIA DeepStream SDK

Sat, 30 Sep 2023 01:15:33 +0200

Introduction

Recently, I got the chance to work on a project dealing with Computer Vision ! In the investigation phase, I discovered an interesting product: the NVIDIA DeepStream SDK ! Even when NVIDIA DeepStream was not adopted for our project 😅 I had a strong desire to discover this platform. I really cannot say if it’s a platform, a set of tools, a set of platforms, or even a full universe. 😊

Playing with Reactive Quarkus

Fri, 27 May 2022 00:00:00 +0000

Here we go again for a new post 😁 After publishing my Quarkus book last September, I got many requests about creating reactive applications with the Quarkus Framework.

Today, I will show you how to make a Reactive CRUD Application with the Quarkus Framework and backed by a PostgreSQL Database.

Building our the Reactive Quarkus Application

The full source code is available on my Github.

We will generate our project using the code.quarkus.io. Our application will need 8 extensions from the portal:

Projects ideas for software engineering students 💡

Tue, 04 May 2021 00:00:00 +0000

During many career talks I attended, I noticed that some questions come back every time: " As a final year student, how can I get an internship? What can I mention in my CV to make it attractive? " 🤔

The problem is that always we start being concerned about internships too late, only some weeks before starting the search operation 💣 Although, finding a good internship needs to be prepared many months before…

Playing with Azure Functions and Quarkus

Tue, 23 Feb 2021 00:00:00 +0000

Quarkus is one of the current trends of the Java ecosystem. I’m already in love with it. I’m using it along with Spring Boot, and when I choose, I choose Quarkus. 😁

This week, I was working on a Batch POC using Azure Functions and Azure Automation. So I thought it will be useful to share the exercise with you. 😁

What I want to do?

I will be taking a small use case: I need a batch that will be invoked at some specific time or manually, checking all the available VMs and starting or shutting down all those that we choose.

Announcing Playing with Quarkus - Workshop Edition 🥳

Tue, 03 Nov 2020 00:00:00 +0000

"Playing with Java Microservices with Quarkus and Kubernetes" is available in Early Access

Fri, 23 Oct 2020 00:00:00 +0000

Today is the big day 🥳🥳 My third book “Playing with Java Microservices with Quarkus and Kubernetes” is available in Early Access 🎉🎊🎈✨

Book cover

I started working on the book starting from June 😁 I spent nearly 5 months presenting the most interesting and powerful features of the Quarkus Framework. When I started the Proof-of-concept, I didn’t have the idea of writing a book on Quarkus, I was just discovering. I found myself spending more and more time reading the documentation, trying some features and extensions, and then I got the idea to write the Quarkus version of my “Playing with Java Microservices” Book 😁

Just finished the first four chapters..

Mon, 10 Aug 2020 00:00:00 +0000

Today, I will not be sharing a tutorial or a review, I will share with you my new book news ! 🥳 I just finished typing the fourth chapter. These four chapters belong to the first part of the story: the MoNoLITHiC dedicated part 🤪 ..

What’s new ?

In my previous book “Playing with Java Microservices on Kubernetes and OpenShift” there was a Docker-only chapter in the middle of the book. Now, in the book, there is no Docker-only chapter, there is a Chapter Zero dedicated for Containerization, with Docker and alternatives ! 😄

My upcoming book: Playing with Java Microservices with Quarkus and Kubernetes

Fri, 10 Jul 2020 00:00:00 +0000

Today, I would like to share with you the title of my new book: Playing with Java Microservices with Quarkus and Kubernetes. I started working on it, since the July 2020.

Playing with Java Microservices with Quarkus Kubernetes will teach you how to build and design microservices using Java and the Red Hat Quarkus Framework.

This book covers topics related to creating Java microservices using Quarkus and deploying them to Kubernetes.

Playing with Reactive Spring Boot

Mon, 01 Jun 2020 00:00:00 +0000

Reactive programming ! Wow ! What a fancy buzzy word ! I waited so much to write a blog post about this trend 😃 I was waiting for the landscape to be mature to made a one-shot tutorial 😁

Today, I will show you how to make a Reactive Spring Boot application, with a Reactive CRUDs using Spring Data Reactive Relational Database Connectivity (R2DBC) with PostgreSQL and for sure the famous Webflux. Don’t be scared if you don’t know any of these topics. We will be introducing all of them smoothly ! 😊

Falling in love with Udacity ⚡️

Thu, 07 May 2020 00:00:00 +0000

Good ! This post has a conclusion into its title ! Udacity was the biggest discovery I’ve made during the COVID-19 lockdown 🤩 I was seeking for an interactive learning platform like DataCamp, where I finished all the trainings that I’m interested on. By the end of the February, I found Udacity while I was searching for some AI/ML intensive course.

Celebrating my 30th birthday & my 1st year in Microsoft

Tue, 05 May 2020 00:00:00 +0000

Today is my birthday and what a wonderful day to celebrate my life, but not only. Today I celebrate my first year in Microsoft, one of the most wonderful years in my career.. a year plenty of great new people, amazing challenges, wellness and happiness. 🎉🎊

When I started working for Microsoft last year, I was the Java developer joining the .Net Gurus town. It was a very exceptional situation for my Java friends, because since I started working in 2012, I was always dealing with the open source world, and Microsoft at that time wasn’t in the same planet as us. I even added a disclaimer to tell my contacts in Linkedin that I will not be leaving Java while joining Microsoft 😂 I will be back to this point later.

Playing with Spring Boot and Kafka on Azure Event Hub

Sun, 01 Mar 2020 00:00:00 +0000

In an enterprise level, it’s obvious for applications to be based on messaging for communication. This is done using a middleware between these applications as a Message Bus that enables them to work together.

One of the most used Messaging solutions is Apache Kafka: Kafka is an open-source stream-processing software platform developed by LinkedIn and donated to the Apache Software Foundation, written in Scala and Java. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds. It is horizontally scalable, fault-tolerant, wicked fast, and runs in production in thousands of companies. Kafka Clusters can be deployed in bare metal or in the Cloud.

Playing with Java from 9 to 13

Sun, 29 Dec 2019 00:00:00 +0000

Since the release of Java SE 8, all the developers were under the charm of the Lambdas, Streams and even there those who fell in love with Nashorn for years (yes there are somewhere in this globe 😅).. With the crazy growth of the Enterprise Development context thru Spring Boot/Cloud, Docker, Kubernetes and the unlimited number of JS frameworks, the infinite patterns and styles of architectures, many developers lost the frequency of being up-to-date with the upstream 🤪

Playing with CQRS and Event Sourcing in Spring Boot and Axon

Fri, 20 Dec 2019 00:00:00 +0000

The Microservices Architecture World, we can meet many concepts and patterns, like the Centralized Configuration, Circuit Breaker, Service Registry and Discovery, etc.. Two of these patterns are the CQRS and the Event Sourcing patterns, coming from the Domain Driven Design planet 🌏 In the most of the use-cases, these two patterns are sold together 😁 in this new tutorial, we will discover what does each one ? why they are usually used together ? and for sure we will implement these two patterns in Java ☕️ obviously 🤓
