Why Java Developers Should Learn Docker in 2023? Hello guys, I have been asking my readers to learn Docker since last year. Why have I been doing this? Because Docker is not just another tool, it's a game-changer, and I firmly believe that every Programmer, be it a Java developer, a C++ developer, or a Web Developer coding in JavaScript, all should learn Docker. The first and foremost reason is that Docker simplifies both the development and Deployment of Software projects, for example, you can deploy a Java Microservice in the same way as a node application once you wrap them in a container. Just like Maven made it easy to maintain project dependencies, Docker takes it to another level by building applications and shipping them into containers.

Top 8 Programming Languages to Learn in 2023 - Best of Lot For the last couple of weeks, I have been doing some research about which programming languages beginners and experienced developers should learn in 2023for better career opportunity, growth and to increase their pay and packages when I stumbled about StackOverflow's Developer Survey. If you have seen them before and it's one of the best surveys for software developers, which provides useful insights about programming and the IT world. One of the things I really liked about this survey was its several lists like the list of top 10 programming languages and the most loved frameworks by programmers. Still, the one I found most useful was the list of high-paying technologies. This is a great list and allows you to choose what you can learn in 2023 to go to the next level in your career in terms of both financial and career growth.

Мессенджеры на работе — это не прокрастинация, или как мы сделали сервис для автотестирования Однажды у нас появилась идея отправлять отчеты о выполнении автотестов в мессенджер Telegram. Постепенно эта идея переросла в сервис, который который позволяет запускать тесты, оповещать об ошибках и получать отчеты в любом мессенджере, где есть возможность интегрировать бота. Помимо доступа к результатам автотестов, бот получил интеграцию с Jira и другими инструментами, которые мы используем в РТЛабс. В данной серии статей мы хотим рассказать нашу историю о том, с чего все начиналось, какие у нас были идеи, какие ошибки мы совершали и как мы их решили в итоговой реализации.

5 Things You Can Gift to Programmers, Software Developers, and Tech Geeks in 2023 Hello guys, it's that time of the year again when you start thinking about gifts for your programmer boyfriend, husband, colleagues, or your near dear ones. Even if selecting presents or gifts were not tough, if your friend happened to be a programmer, it becomes slightly tougher. You might have heard that Programmers are aloof, nerds, and tech freaks, well, you heard it right. Programmers prefer to be alone in their own world, but they also like gifts, and you got it right; they are a nerd, so they love books, gadgets, music, and something which helps them to learn something, like a Udemy, Educative, ZTM Academy, or Pluralsight membership.

10 Projects To Learn Web Development in 2023 Hello guys, if you want to learn web development in 2023 then let me tell you that there is no better way to learn web development than building projects. Creating real world application give your experience which you can mention in your resume. They also expose you to challenges which real projects face like authentication, authorization, security, logging, performance etc. You also tend to remember things longer when you actually use it. So if you have learned API and methods by watching courses but haven't used them on any project then you will most likely forget them but if you use them in any project, you will retain knowledge for a long time. That's why I have been saying to may readers to build projects in 2023. Java Interview questions and tutorials Read: http://www.java67.com/2022/12/10-projects-to-learn-web-development-in.html

Использование Postgres в качестве очереди сообщений Базы данных не являются очередями сообщений — это устоявшееся утверждение, которое обсуждалось во многих статьях в блогах и презентациях на конференциях. Но с развитием реляционных баз данных выдерживает ли это утверждение проверку? Если посмотреть на современные версии Postgres, то ответ часто оказывается отрицательным. Поэтому в этой статье рассматривается упрощенный механизм уведомлений Postgres и обсуждается, как его можно использовать для реализации простой, но эффективной очереди сообщений на основе push-уведомлений. В ней также рассматривается использование этой очереди для взаимодействия между репликами в развертывании Kubernetes и реализация библиотеки для универсальной обработки задач.

10 Projects You can Build to Learn Spring Boot in 2023 Hello guys, I have always said that there is no better way to learn anything then actually doing it and its 100% true for Spring Boot, one of the popular Framework for Java application Development. In my 20 years of experience, I have found that the best way to learn Java and Spring Boot is building projects. When you build project, common task surface them like creating a List or sorting a List and then you research and learn. Those learning stuck and make you better developer. Building project also have many advantage like it allows you to use a lot of technologies like Git, IntelliJIDEA, Hibernate, APIs etc together to build something which you can showcase to your potential employer.
