There are strong reasons why Node.js is so popular nowadays. Async programming model, cross-platform with a large community and open-source modules. It’s possible to write server-side on JavaScript, and it is fast and efficient. Node.js is designed to handle multiple asynchronous I/O operations efficiently. Node.js apply different execution types, and this article will explain how execution types work with practical usage in Node.js. Types of Execution V8 engine compiles JavaScript code into machine code that will be performed by the computer’s processor, which can have multiple cores. Node.js has only one main event loop thread, a mechanism used to handle async and non-blocking I/O operations. Non-blocking means an asynchronous programming paradigm that allows you to perform several operations at the same time without blocking the execution of the main program.

Microservices Decoded: Unraveling the Benefits, Challenges, and Best Practices for APIs

Aggregated on: 2023-05-15 14:45:33

In today's fast-paced software development landscape, microservices have emerged as a popular architectural pattern. But what exactly are microservices? In a nutshell, microservices are a way of structuring an application as a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This architectural style enables teams to develop and deploy services independently, offering flexibility and scalability to the software development process. The fundamental idea behind microservices is to break down an application into smaller, self-contained services, each responsible for a specific business capability. Let's take the example of an online marketplace application. Instead of treating the entire application as a monolithic entity, microservices architecture allows us to identify distinct features like search, shopping cart, payments, and order history as independent services. These services can be developed and maintained separately, promoting code modularity and enhancing overall system agility.

Fun Is the Glue That Makes Everything Stick, Also the OCP

Aggregated on: 2023-05-15 13:30:33

This is part two of my series on the OCP-17. In my first post, I explained why it’s still worthwhile to tackle the trick questions and arcane details of this exam. Each of us has our own sense of how much knowledge is good enough to get a job done, like writing Java code. The examiners at Oracle probably put the bar much higher than you. If you can’t somehow make the journey fun, you’re bound to give up. So, your motivation needs an upgrade, and you must put in the right practice. In this post, we will look at both. Amateur Versus Professional Practice Not all practice makes perfect. Poor practice doesn’t even make you proficient. It’s not the hours that count, although Malcolm Gladwell in Outliers claimed you need at least 10,000. This sweeping statement with its conveniently round number is questionable science, to say the least. Excellence itself is not a well-defined notion. People’s innate aptitudes are not created equal. Some are born geniuses. But most importantly, the hours you put in must be effective.

Boosting Similarity Search With Stream Processing

Aggregated on: 2023-05-15 13:30:33

The goal of similarity search and vector databases is to find similar results to the search query for unstructured data, such as text, images, and videos. The unstructured data first is vectorized, and stored in a vector format. There are publicly available tools to create vectors from unstructured data; similarly, there are vector databases to store and perform similarity searches. This is important because of the rising popularity of Large Language Models (LLMs) and their combination with vector databases. Here, we present a hybrid approach by taking the strengths of vector databases and boosting them with traditional search and filtering techniques based on real-time stream processing. Vector databases are good for building high-performance vector search applications. On the other hand, Hazelcast can be used for real-time stream processing and fast data storage for structured data (filters, tags, and contextual data). Some vector databases offer filtering on structural data, which can be used or replaced with Hazelcast. In either case, Hazelcast can be used to enrich your query results, from additional resources.

10 Traits That Separate the Best Devs From the Crowd

Aggregated on: 2023-05-12 22:15:32

In a Nutshell We work hard to improve our tech and soft skills. But our character traits, our mindset - we take it for granted. An innate, fixed part of who we are. And thus, we let it run on autopilot. This way of thinking is harmful. Not only is your mindset critical for a successful software development career (maybe even more than your skills), but it's also under your control. True senior devs acknowledge that character traits are malleable, are self-aware of their mindset, and deliberately work on it. This is the superpower that makes them stand out from the crowd and accelerates their career. In this post, I'll discuss the 10 most critical traits of a successful developer, why they are important, and share a few tips on how you can shape them. Three Things You Need To Succeed as a Software Developer Professional software development is a complex discipline that requires a diverse set of abilities to succeed. We can group them into three main categories: Technical Skills This is the most obvious group. To be a successful developer, you need to be good at your trade: programming languages and frameworks, clean code principles, architecture, testing, debugging, and so on. You also need to be skillful with your tools: version control, command line, and IDE.

How To Implement Istio Ambient Mesh in GKE or AKS

Aggregated on: 2023-05-12 18:30:32

Why Do You Need Istio Ambient Mesh? It is given that Istio is a bit resource intensive due to sidecar proxy. Although there are a lot of compelling security features that can be used, the whole Istio (the sidecar) has to be deployed from day one. Recently, the Istio community has reimagined a new data plane — ambient mode — which will be far less resource-intensive. Istio ambient mesh is a modified and sidecar-less data plane developed for enterprises that want to deploy mTLS and other security features first and deploy an advanced network later.

Managing Data Residency: Concepts and Theory

Aggregated on: 2023-05-12 17:30:32

Cloud computing has opened a Pandora's Box of many original issues compared to sound old on-premise systems. I believe that chief among them is data residency or data location: Data localization or data residency law requires data about a nation's citizens or residents to be collected, processed, and/or stored inside the country, often before being transferred internationally. Such data is usually transferred only after meeting local privacy or data protection laws, such as giving the user notice of how the information will be used and obtaining their consent.

Enriching Kafka Applications With Contextual Data

Aggregated on: 2023-05-12 12:30:31

Developing high-performance large-stream processing applications is a challenging task. Choosing the right tool(s) is crucial to get the job done; as developers, we tend to focus on performance, simplicity, and cost. However, the cost becomes relatively high if we end up with two or more tools to do the same task. Simply put, you need to multiply development time, deployment time, and maintenance costs by the number of tools. Kafka is great for event streaming architectures, continuous data integration (ETL), and messaging systems of record (database). However, Kafka has some challenges, such as a complex architecture with many moving parts, it can’t be embedded, and it’s a centralized middleware, just like a database. Moreover, Kafka does not offer batch processing, and all intermediate steps are materialized to disk in Kafka. This leads to enormous disk space usage.

Repeatable Database Updates via Liquibase

Aggregated on: 2023-05-11 20:30:31

The main purpose of this tutorial is to present a way of detecting modifications to a stored Liquibase change set that was previously applied and execute it again automatically. In order to illustrate this, a small proof of concept is constructed gradually. In the first step, the application configures Liquibase as its migration manager and creates the initial database schema. Then, modifications are applied to the running version, and lastly, the repeatable script is introduced and enhanced. Set-Up Java 17 Spring Boot v.3.0.2 Liquibase 4.17.2 PostgreSQL 12.11 Maven Proof of Concept As PostgreSQL was chosen for the database layer of this service, first, a new schema is created (liquirepeat). This can be easily accomplished by issuing the following SQL command after previously connecting to the database.

Non-Volatile Memory

Aggregated on: 2023-05-11 20:30:31

Non-volatile memory access (NVM) is a technology that has gained significant attention over the past few years. It has brought a revolution in the memory storage industry by providing various benefits over traditional storage technologies. NVM refers to a type of memory that retains data even after the power has been turned off. This means that data stored in NVM is non-volatile and is suitable for use in a wide range of applications. In this article, we will explore the various forms of NVM, their advantages, limitations, and their potential applications. Forms of NVM NVM comes in various forms, including flash memory, magnetic RAM (MRAM), nanotube RAM (NRAM), resistive RAM (RRAM), and phase-change memory (PCM). Flash memory is the most commonly used form of NVM, and it is used in USB drives, digital cameras, and smartphones. Flash memory works by trapping electrons in a transistor’s floating gate. This makes it non-volatile as the information is retained when the power is off. The limitations of flash memory include wear-out and a limited number of write cycles.

Opportunities for Growth: Continuous Delivery and Continuous Deployment for Testers

Aggregated on: 2023-05-11 16:45:31

Development practices are constantly changing, and as testers, we must embrace change. One of the changes that we can experience is the move from monthly or quarterly releases to continuous delivery or continuous deployment. In addition, this move to continuous delivery or deployment offers testers the chance to learn new skills. A project that makes monthly or quarterly releases has a familiar rhythm, and the team builds toward the release date. The testers must test all the cards and conduct manual regression testing. Every test in the manual scripts needs to be executed, and possibly a report needs to be made on the results of these tests. Once the release has been made, it is possible that there will be bugs that were in the release that need to be fixed. The testers will also need to start running the same manual regression tests on the next release and report on them again. Testing for monthly or quarterly releases is a repetitive process. This process has been compared to the Greek myth of Sisyphus, who had to roll a stone to the top of a hill, and then when the stone rolled to the bottom of the hill, he had to roll it to the top of the hill again.

The cloud platforms provide customers with technology and tools to protect their assets, including the most important one — data. At the time of writing, there's a lot of debate about who's responsible for protecting data, but generally, the company that is the legal owner of the data has to make sure that it's compliant with (international) laws and standards. In the UK, companies have to adhere to the Data Protection Act, and in the European Union, all companies have to be compliant with the General Data Protection Regulation (GDPR). Both the Data Protection Act and GDPR deal with privacy. International standards ISO/IEC 27001:2013 and ISO/IEC 27002:2013 are security frameworks that cover data protection. These standards determine that all data must have an owner so that it's clear who's responsible for protecting the data. In short, the company that stores data on a cloud platform still owns that data and is therefore responsible for data protection.

CloudFront vs. CloudFlare: Choosing the Right CDN

Aggregated on: 2023-05-10 19:30:30

Content Delivery Network (CDN) is not a new technology. In fact, it has been around for many years. Every internet user, knowingly or unknowingly, uses a CDN while watching a video, reading a newspaper, or enjoying a TV show. As CDN solutions become mainstream, organizations must choose the right CDN platform to seamlessly and securely serve content to end-users. CloudFront CDN and CloudFlare CDN are two popular services available on the market. This blog delves deep into the CloudFront vs CloudFlare debate to explore the similarities, differences, and features of both solutions in order to help organizations make an informed decision. What Is a CDN? CDN stands for content delivery network. It’s a network of geographically distributed servers and data centers designed to deliver higher performance and high availability of internet content. Whether streaming videos, high-resolution images, JavaScript files, or HTML pages, a CDN solution facilitates a quick transfer of site assets, ensuring faster delivery of website content.

What Are Events? Process, Data, and Application Integrators

Aggregated on: 2023-05-10 19:30:30

I first started developing SAP "Workflows" 25 years ago: five years prior to Gartner announcing that 'Event-Driven Architecture' (EDA) would be the "next big thing" to follow on from 'Service-Oriented Architecture' (SOA) – SOA likewise still in its infancy in 2003. What's interesting about this is that Workflows themselves are, and always have been, 'Event-Driven.' The advancement of any given Workflow from one step to the next step always depends upon a particular event (or events) occurring, such as 'PurchaseOrder.Approved'. As you might already know, SAP has been developing ERP software since 1972, making it by far one of the most experienced software vendors in the world to have built their product offerings around 'Business Processes': around 'Process Integration.' What's also interesting to note in this regard is that SAP very recently confirmed the tight link between 'Workflows' and 'Process Integration,' by regrouping and rebranding their Cloud-based "Workflow Management" solution into a new offering: "Process Automation" – apparently the first time in 25 years that their Workflow solution carries a name other than "Workflow …"

Classloaders in JVM: An Overview

Aggregated on: 2023-05-10 19:00:30

Classloaders are an essential part of the Java Virtual Machine (JVM), but many developers consider them to be mysterious. This article aims to demystify the subject by providing a basic understanding of how class loading works in the JVM. What Are Classloaders In the Java Virtual Machine (JVM), classes are loaded dynamically and found through a process called class loading. Class loading is the process of loading a class from its binary representation (usually a .class file) into memory so that it can be executed by the JVM. This is where we need classloaders. Class loaders are used to load .class files into the memory.

Why Run Open Source Data Technologies in Your Own Cloud Account

Aggregated on: 2023-05-10 18:30:30

Organizations have an increasingly important choice to make when enlisting managed services or database-as-a-service (DBaaS) providers for their open-source data technologies: go with one of the many providers that require data management to be hosted within their own domains, or insist on running in your own (cloud) provider account (RIYOA). In general, most DBaaS providers offer the simplicity of having just one bill to pay, which covers all cloud costs and instances. However, that simplicity comes at costs beyond the monetary—reduced visibility of what’s going on with your data, limitations to developer flexibility when trying to utilize data-layer technologies and restrictions on access to data itself. While less of an out-of-the-box option, retaining RIYOA control avoids these shortcomings and makes it significantly easier to shift to a new provider if a change becomes preferable at some point.
