Another LTS Java release is already here, bringing some exciting changes and improvements. Let’s analyze the most important Java 21 features, check out how they work in practice, and try to predict their significance for the future of this technology. By Arkadiusz Rosłoniec.

Since the Java platform adopted a six-month release cycle, we’ve moved past the perennial questions such as “Will Java die this year?” or “Is it worth migrating to the new version?”. Despite 28 years since its first release, Java continues to thrive and remains a popular choice as the primary programming language for many new projects.

The article then highlight several Java 21 JDK Enhancement Proposals (JEPs) that author believes are particularly noteworthy:

• String Templates
• Sequenced Collections
• Pattern Matching for switch and Record Patterns
• Virtual Threads

Most of features aren’t as groundbreaking as some of the things introduced in JDK 17, but they’re still very useful, and nice to have QOL (Quality of Life) changes. Overall, the advancement Java made in various areas signals the team’s ongoing commitment to improving efficiency and performance in high-demand applications. Good read!

Discover over 55 cloud statistics, including stats around forecasts, cloud waste reports, cloud cost optimization efforts, and data on hybrid cloud adoption rates. By Cody Slingerland.

The trend continues to accelerate – even faster now. Cloud computing was already booming before 2020. But in the following two years, remote work flourished, and cloud adoption soared.

Yet there’s more to the rise and rise of cloud computing than remote working. For example, cloud infrastructure also supports big data analytics, Artificial Intelligence (AI), Machine Learning (ML) models, the Internet of Things (IoT), and advanced Business Intelligence (BI). So, we compiled the following remarkable cloud computing statistics from reliable sources to help you keep up-to-date.

Some of the stats mentioned:

• Globally, the cloud computing market will surpass $1 trillion by 2028. (Precedence Research)
• The global cloud computing market grew from $24.63 billion in 2010 to $156.4 billion in 2020. That’s a 635% jump.
• Only 3 out of 10 organizations know exactly where their cloud costs are going (CloudZero, The State Of Cloud Cost Intelligence 2022 Report)
• A cloud bill can comprise hundreds of millions or billions of rows of data (FinOps Certification)
• An Amazon Cost & Usage Report is too large to load into Excel all at once. Instead, Amazon splits its monthly CUR into many separate files. Good luck understanding them. (FinOps Certification)
• You can reduce your Total Cost of Ownership (TCO) by as much as 40% by migrating your business to the public cloud (Accenture)

Authors have also included tips, tricks, and tools to make cloud computing work for you. Yes, that includes practical tips on how to manage and optimize your cloud costs across AWS, Azure, GCP, Kubernetes, and Snowflake within a single platform. Nice one!

Let’s compare Flutter and Kotlin a little more directly, based on a number of key factors. By Flatirons.

Kotlin Multiplatform, an extension of the Kotlin programming language, presents a compelling alternative comparable to Flutter in the realm of cross-platform development. It enables developers to seamlessly share and reuse code across a diverse range of platforms, such as Android, iOS, web, and desktop. This feature of Kotlin Multiplatform is particularly advantageous for writing and maintaining common business logic and data processing code, as it allows these components to be written just once and then efficiently deployed across various platforms.

This article then provide information on following topics:

• What is Flutter?
• What is Kotlin?
• What is Kotlin Multiplatform?
• Flutter vs. Kotlin breakdown
• When is Kotlin better than Flutter?
• When is Flutter better than Kotlin?

In essence, Kotlin is the ideal choice for projects that demand comprehensive Android functionality and benefit from a team with Java experience. However, for broader cross-platform needs or when the focus is on rapid development and deployment across multiple platforms, Flutter still stands out as a more fitting option. Consider your project’s specific requirements and your team’s expertise to make the most informed decision.

In summary, Flutter is the go-to framework for scenarios that demand rapid development, aesthetically pleasing UIs, and cross-platform functionality, especially when the project does not require intensive use of platform-specific Android features. Its capacity to swiftly produce quality apps for both Android and iOS makes it an appealing choice for a wide range of development projects. Good read!
