Students will also be able to start writing code without having to learn all the concepts that are inherent in large projects right from the start. This will allow them to learn the language more gradually.

“The new enhancements in Java 22 enable more developers to quickly and easily create applications that are feature-rich, scalable and secure, and that help organizations around the world grow their businesses,” said Georges Saab, senior vice president of Oracle Java Platform and chairman of the OpenJDK board.

The version introduces the use of unnamed variables and templates that are highlighted. These are useful when variable declarations or nested templates are required, although they will not be used. According to Oracle, this new feature will reduce the number of errors, improve the readability of record templates, and increase code maintainability.

Another anticipated feature that has made its way into this release is the API for foreign functions and memory, which allows Java code to interact with code and data outside of the Java Runtime without using the Java Native Interface.

JEP 458 also introduces the ability to allow the Java runtime to run a program that is provided as multiple Java source code files.

Java 22 also includes JEPs in the preview, including APIs for class files and Stream Gatherers, and several in the second preview, such as Structured Concurrency and Scoped Values.

Vercel’s Next.js 14 brings with it a host of improvements in performance. Notably, it boasts a 53% reduction in local server startup times and a remarkable 94% increase in code update speed thanks to the implementation of Fast Refresh.

Over 5,000 “next dev” integration tests are successfully passing using Turbopack, the underlying Rust engine powering Next.js. This advancement promises developers a more efficient and dependable performance when employing “next dev –turbo.”

The feature Server Actions enables developers to define asynchronous server functions, offering a versatile set of capabilities, including data revalidation, route redirection, and cookie management, among other functions.

“Having great performance globally and personalization shouldn’t come at the cost of complexity”, Lee Robinson, VP of developer experience at Vercel, and Tim Neutkens, engineering manager for Next.js, noted in a blog post.

Vercel has separated blocking and non-blocking metadata, and they are currently phasing out a number of metadata options. This deprecation includes viewport, colorScheme, and themeColor, which will be replaced by a set of fresh metadata alternatives.

In addition to the Next.js 14 release, Vercel has unveiled an exciting addition to their educational offerings. This include Next.js Learn, which delves into a variety of topics. The course covers everything from the Next.js App Router and Tailwind CSS to techniques for optimizing fonts and images, as well as insights into creating layouts and pages, and much more.

It also has a number of other features and additional capabilities. C++ plays an important role in many modern and state-of-the-art systems, such as databases, web browsers, operating systems, and others that have used C++ in at least some part of their databases.

In this article we will present to you top 5 interesting facts about C++, presented by TechWibe.

Top 5 Curious Facts About C++ You Didn’t Know

It was originally known as “The New C”.
Did you know that computer programmer Rick Massity actually gave the name to C++? His reasoning was that the ++ in the name represented an improvement over the original C programming language.

C++ is most inspired by C. C++ is also built on the same framework, but of course, new features and capabilities have been added to the language.

Has a rich library support
The C++ language has the STL or standard template library. If you don’t know, the STL is extremely useful as it helps to quickly prepare codes when needed. It basically consists of four components namely iterators, functions, containers and algorithms.

Iterators help in dealing with a sequence of values. Functors allow to customize the operation of the associated function using the required support of the passed parameters.

Containers have classes in them to implement various data structures that are commonly used, such as vectors, lists, sets, maps, etc. Finally, the algorithms can be of different kinds, such as search, sort, etc.

A steep learning curve
Several programmers join the world of C++ or C, but they fail to keep mastering and to learn these languages well. It is mostly because they feel irked in catering to low-level programming elements, like the multi-thread data races, memory storage model, pointers, templates expansion, address alignment, and others. When these elements are not handled well, the application has a possibility of crashing. This can be pretty frustrating for a new programmer.

It powers the world
The truth is that C and C++ are everywhere. These two languages alone power more technology than we give them credit for. The kernels of as many operating systems as Android, iOS, Mac, Linux, and Windows are coded in C. In addition, modern game engines are also widely available and coded in C++ or C, such as Unreal Engine, Unity 3D, cocos2d-x, and others.

C++ has over thirty-five operators
Did you know that C++ has more than thirty-five operators. They range from comparisons to logical operations, bit handling, arithmetic, and more. Virtually any of these thirty-five operators can be overloaded for certain types.

This wide variety of operators makes C++ programming language user definitions more like built-in types.

Here are the five basic concepts that underlie all programming languages according to Analytics Insights.

Variables and Data Types
Variables are placeholders in memory that store data during the program’s execution. They allow programmers to give names to memory locations, making manipulating and managing data easier. Each variable has a specific data type that defines the kind of data it can hold, such as integers, floating-point numbers, characters, or strings.

Control Structures
Control structures allow programmers to control the flow of a program’s execution. They determine how and when certain blocks of code will be executed based on certain conditions. The most common control structures include:

Conditional Statements: These statements, such as if, else if, and else, allow the program to execute different code blocks depending on whether certain conditions are true or false.

Loops: Loops enable the program to repeat a certain block of code multiple times, making it easier to perform repetitive tasks.

Functions and Procedures
Functions and procedures are reusable code blocks that perform specific tasks. They help in breaking down complex programs into smaller, manageable parts, making code more organized and maintainable.

Functions: Functions return a value after performing a specific computation or task.

Procedures: Procedures are similar to functions but do not return any value; they execute a series of steps or actions.

Input and Output
Input and output operations are essential for user and program communication. These operations enable the program to read data from the user and display results or information.

Object-Oriented Programming (OOP)
Object-Oriented Programming is a powerful programming paradigm that revolves around the concept of objects. Objects are instances of classes, which are user-defined data types that encapsulate both data and the functions that operate on that data. OOP promotes the reusability of code and allows for better organization and structure in large projects.

In OOP, the four main principles are:
-Encapsulation: Hiding the internal details and exposing only necessary functionalities;
-Abstraction: Representing the essential features of an object while hiding unnecessary details;
-Inheritance: Creating new classes that inherit the properties and methods of existing classes;

In the January edition of this year’s Go Developer Survey, 5,844 Go developers were asked to share how they use the language, what their biggest challenges are in using it, and what their top priorities are for future improvements to the language.

Error handling, the readability and verbosity of errors in Go, and the difficulty in learning Go programming best practices were the most commonly reported challenges. Generics, which simplify coding by allowing developers to write functions that are independent of the types used, officially appeared with Go 1.18 in March 2022. After that introduction, comments about generics waned.

Other survey results indicate that maintainers of Go’s open source modules report challenges in keeping dependencies up-to-date and avoiding outages due to version changes and downtime. It is expected that this area will be investigated further to help maintainers ensure a stable and robust ecosystem. The survey also found that novice Go developers are interested in using Go for web development.

Some of the updates include tools for creating apps on top of Slack, including the Slack CLI – Slack’s command-line interface for interacting with apps – and the TypeScript SDK. More secure data storage and better sharing capability to connect created products with other users.

The new modular architecture includes three basic units: functions, triggers, and workflows.

The company is expected to update its no-code Workflow Builder later this year to allow users to automate Slack and integrate commonly used tools. Workflow Builder will let users create functions and workflows by mixing triggers, inputs and outputs with functions for their most commonly used software.

“The new architecture is very consistent with trends in IT infrastructure that promote composable solutions. And they are turning more controls over to users to innovate.”

said Dan Miller Opus Research analyst.

According to Miller, the next frontier for Slack will be generative artificial intelligence. Microsoft has already incorporated its Copilot generative AI into Teams to create reviews and task notes by synthesizing text from messages.

The updated developer platform comes two years after Salesforce acquired Slack for $27.7 billion. Salesforce’s own collaboration platform, Chatter, never really caught on, even after it was revamped to include social messaging tools for marketers.

The new RTX 4070 chip, which Nvidia will start shipping today, will cost $599, putting it near the middle of the company’s lineup of graphics processing units (GPUs) priced as high as $1,600.

The RTX 3060 is the fourth most popular gaming chip on the market, according to data from a March survey by gaming distribution platform Steam.

Although Nvidia’s data center chips for training artificial intelligence systems, such as ChatGPT, have boosted the company’s revenue growth in recent years, the company still gets about a third of its $26.9 billion in fiscal 2023 revenue from gaming chips, even though gaming revenue is down 27%, hit by a general decline in the PC market.

Nvidia chips help PC video games render images on high-resolution screens faster to make games look more realistic. The 4070 chips will be the cheapest chips available that use Nvidia’s latest artificial intelligence technology for this purpose.

The latest version of TypeScript includes a host of improvements that make the language smaller, simpler, and faster. Today we’ve chosen to bring you some of the major changes in TypeScript 5 according to Developer Tech.

Top 7 Key Changes in TypeScript 5

Variadic tuple types
Variadic tuple types allow developers to define tuple types with a variable number of elements.

In previous versions of TypeScript, the number of elements in a tuple was fixed, making it difficult to work with functions that have a varying number of arguments. With variadic tuple types, developers can now define a tuple type with a spread element, which can take any number of arguments.

Key remapping in mapped types
Mapped types in TypeScript allow developers to create new types by mapping over an existing type.

In TypeScript 5, mapped types now support key remapping, which allows developers to rename keys when creating a new type. This is especially useful when working with third-party libraries that use different naming conventions.

Smarter type inference
TypeScript 5 introduces several improvements to its type inference system, making it smarter and more accurate. For example, TypeScript 5 can now infer types from destructured arrays and objects, making it easier to work with complex data structures.

Additionally, TypeScript 5 can now infer types from default function arguments—making it easier to write reusable code.

Abstract construct signatures
TypeScript 5 introduces a new feature called abstract construct signatures, which allows developers to define abstract classes with a constructor signature. This makes it easier to create abstract classes that can be extended by other classes, as it provides a clear definition of the class’ constructor.

Stricter class property initialisation
TypeScript 5 introduces stricter rules for class property initialisation. In previous versions of TypeScript, it was possible to declare a class property without initialising it, which could lead to runtime errors.

With TypeScript 5, all class properties must be initialised either in the constructor or with a default value.

Improved error messages
TypeScript 5 comes with several improvements to its error messages, making it easier to diagnose and fix issues in your code. For example, TypeScript 5 now provides more detailed error messages for type mismatches, making it easier to identify where the error occurred.

Faster compilation
TypeScript 5 introduces several performance improvements, making compilation times faster. This is especially noticeable when working with large projects, as TypeScript 5 can now process files in parallel, reducing overall compile times.

The new platform, Chainlink Functions enables the execution of custom computations on top of Web 2.0 APIs within minutes through its network.

“Our goal is to enable developers to combine the best of web3 smart contracts with the power of Web 2.0 APIs,”

El Moujahid said

Chainlink connects data in the chain to external systems to enable smart contracts to execute transactions based on real inputs and outputs. According to the platform’s website, it has enabled more than $7 trillion worth of transactions since mid-February.

Chainlink Functions hopes to be the bridge between the two parties to create mass adoption.

“Web3 is not going to be a binary thing. I’ve seen this in AI. The path to mass adoption was making it easy to embed AI into your apps. It’s the same with web3. You don’t have to build your entire app on-chain. It’s going to be a spectrum: part smart contract; part Web 2.0 APIs.”

El Moujahid said.

The new platform also supports more widespread programming languages such as JavaScript so that developers unfamiliar with Web3 can get into the field. It will also provide integration with Amazon Web Services (AWS), Meta, and others.

With Meta for example, web3 developers can connect social media activities and small e-commerce businesses with a smart contract using Chainlink Functions and automatically trigger actions on-chain based on off-chain activities.

The platform’s serverless nature also means developers can stop worrying “about the overhead of managing and securing the infrastructure on which their code will run,”

El Moujahid said.

El Mujahid also shares that the platform is currently in private beta mode on Ethereum and Polygon’s test networks. Additionally, Chainlink plans to expand its functionality to more blockchains, add new integrations and tools, and launch on the main network as soon as possible.

Here are the most common myths about software developers according to The Server Side

The additional developer will speed up the work process
In fact, the truth is that when a new developer is added to the team, there is always an initial drop in productivity because bringing a new developer into the project takes time, and adjusting to the project takes time away from the team’s development-focused activities.

Furthermore, in the world of software development, smaller teams have proven to be more product, adaptable and agile than larger ones. That’s why the Scrum Framework limits teams to 10 members, which includes the Scrum Master and the Product Owner. And let’s not forget Brooks’ laws, which state: Adding manpower to a late software project makes it later.

Developers aren’t creative
Software development requires a great deal of creativity. Yes, almost anyone can learn an API. But the ability to use an API, to apply an API to an unsolved problem requires a great deal of creativity. The people who excel on the software development team are the ones who twist and turn methods and functions in unpredictable ways and come up with incredibly creative solutions to difficult and complex problems.

Open source software is less secure
Many believe that because the source code of open source software is publicly available, any hacker with nefarious intentions can easily crack that code. In fact, the opposite is true. With open source software, hundreds, if not thousands of people will scour through updates, enhancement and even stale source code that hasn’t been touched in years.

All of those developers regularly testing and checking the codebase will make open-source software more secure than proprietary software that only has a handful of programmers maintaining it.

All programming languages are the same
At the core, all programming languages perform three functions. But when you get beyond those basics, that’s not exactly how things are.
And one more thing that is more than proof. On social media, there are always arguments about which language is best and why. And absolutely every one of you has witnessed at least one argument, right? If all programming languages were the same, these flame wars would subside quickly, but that’s not the case. They continue because it is a software myth to claim that all programming languages are the same.

Programming is boring
What? It’s amazing how full of life one becomes when working on a software project that engages and challenges them.

And any developer who’s been in the industry for years will undoubtedly be able to tell you stories of working late into the morning to solve a problem, and then waking up early and heading straight to the keyboard to test the inspiration that woke him from sleep.

The project is absorbing, fascinating and gives meaning to your life! You feel fulfilled and satisfied, and what’s better than that.
