Service Mesh 101: The Role of Envoy

Aggregated on: Sat Jan 29 2022 20:04:46 GMT+0000 (Coordinated Universal Time)

If you’ve done any reading about service meshes, you’ve probably come across mentions of an open-source project named Envoy. And if you’ve done any reading about Envoy, you’ve probably seen references to service meshes. How are these two technologies related? How are they different? Do they work together? I’ll attempt to answer all those questions in this blog post’s first and second parts, plus possibly a few more. What Is a Service Mesh? As companies are increasingly re-architecting their applications and embracing a microservices-based approach, the need for solutions to traffic management, observability, security, and reliability features increases. A service mesh is one approach to adding these features to the underlying platform instead of individual applications or services.

Getting Started With JPA/Hibernate

Aggregated on: Sat Jan 29 2022 18:49:46 GMT+0000 (Coordinated Universal Time)

JPA was born as the acronym for Java Persistence API. When Java EE was donated to the Eclipse Foundation under the Jakarta EE project, the name of the API changed to Jakarta Persistence but the term JPA is still in use. JPA solves the object-relational impedance mismatch by allowing you to map Java objects to database tables and is one of the most (if not the most) used persistence frameworks for Java. JPA is an API specification that someone can implement–JPA providers or implementations. The most popular JPA implementation is Hibernate ORM. You can use Hibernate ORM without JPA or through JPA. One potential advantage of using it with JPA is that you can move between implementations if you want (something I have never seen happening, though). Another advantage is that someone with experience in, say EclipseLink or Apache OpenJPA, then they can use at least part of that experience when moving to Hibernate.

There is no doubt cracking the Coding interviews of top tech companies like Google, Microsoft, and Amazon is very hard, but you can still crack it by carefully planning and preparing the essential skills which matter most like Data structures and Algorithms, System Design, Multithreading and Concurrency, SQL and Database design, and of course, problem-solving skills. Being an author of Java and a programming blog, I often receive queries about how to prepare for coding interviews? How to pass Google or Microsoft Software Developer interviews? Or how can I get a software development job on Amazon or Facebook?

Building Two-Factor Authentication With NestJS and Postgres

Aggregated on: Sat Jan 29 2022 17:34:46 GMT+0000 (Coordinated Universal Time)

Introduction Cybercrime and hostile operations against public and private entities have become more prevalent in recent years. This rise in risk explains why many software companies are adding an extra layer of security to their customers' accounts. 2FA is an extra layer of security that confirms that the person seeking to get into an online account is who they say they are. A user's username and password must be entered first. They will then be asked to provide additional details before being granted access. This approach will protect a compromised account from fraudulent activities. Even if a hacker discovers the user's password, they will not be able to login into the account because they lack the second-factor authentication ( 2FA) code.

Down With Cookie Walls, Give Us the Web Privacy API!

Aggregated on: Sat Jan 29 2022 17:04:46 GMT+0000 (Coordinated Universal Time)

Google, Facebook, other advertisers profile us and invade our privacy in all ways imaginable. Lawmakers are always behind, cookie walls and opt-out schemes don’t do much, except ruining the web. Is there a better way? How about a new, GDPR-enforced Web Privacy API? This article lays out a design for an alternative, in form of an RFC. A few days ago Google announced that it's killing FLoC. The invasive tracking technology, announced in 2021, met with widespread opposition, is finally being dropped, but only to be replaced with the Topics API. This new proposal is technically different, but it still aims at the same goal:

What Java Developers Need to Know About Geo-Distributed Databases

Aggregated on: Sat Jan 29 2022 15:49:46 GMT+0000 (Coordinated Universal Time)

I’ve been working with distributed systems, platforms, and databases for the last seven years. Back in 2015, many architects began using distributed databases to scale beyond the boundaries of a single machine or server. They selected such a database for its horizontal scalability, even if its performance remained comparable to a conventional single-server database. Now, with the rise of cloud-native applications and serverless architecture, distributed databases need to do more than provide horizontal scalability. Architects require databases that can stay available during major cloud region outages, enable hybrid cloud deployments, and serve data close to customers and end users. This is where geo-distributed databases come into play.

Nemo - The Ubuntu File Manager You Didn’t Know You Needed

Aggregated on: Fri Jan 28 2022 16:04:45 GMT+0000 (Coordinated Universal Time)

So… I finally got bored with Nautilus. Ubuntu has been my daily driver for the last several years. I remember when Linux used to be a second-class citizen in the desktop space, only used by nerds and devs who could unravel its arcane and obscure mysteries. But it has come a long way. Not only is it a lot more user-friendly with a plethora of customization options, but Steam, and especially Proton, has added first-class gaming support for Linux. I haven’t had a dual boot Ubuntu/Windows system in quite a while and that’s a huge win.

Writing Clean and Consistent Code with Static Analysis using PMD and Apex

Aggregated on: Fri Jan 28 2022 14:04:45 GMT+0000 (Coordinated Universal Time)

One of the key requirements to developing good, maintainable software is to ensure that it works under a variety of conditions. This is typically done by automating a suite of tests on the various features and code paths your application can take. While unit tests are excellent for making sure that your application technically runs, there’s another category of verification which ensures that your application has no other detectable issues: static analysis. Static analysis is a method of analyzing your code without executing it. If you’ve ever worked with a compiled language like Kotlin, the compiler implements one form of static analysis by ensuring that your program adheres to the grammatical rules of the language. For example, if you call a function but forget to pass in required arguments, a static analyzer alerts you to this error before you compile your application. This is in contrast to an interpreted language such as JavaScript, in which the error would occur when executing the code because there’s no compiler to anticipate the issue.

The Role of CI/CD Pipeline in Software Development

Aggregated on: Thu Jan 27 2022 21:19:45 GMT+0000 (Coordinated Universal Time)

The CI/CD pipeline includes continuous integration, delivery, and deployment. DevOps teams use it to generate, test, and release new software automatically. This pipeline benefits from regular software changes and a more collaborative and agile team process. You've probably heard about the benefits of CI/CD tools, which are used to provide code more frequently and reliably. Let's examine what it is and how it benefits software development. What Does CI/CD Pipeline Stand For? There are two abbreviations for CI and CD: CI stands for continuous integration and CD for continuous delivery and deployment. The software development methodology is known as Continuous Integration, and Continuous Deployment (CI/CD) is based on the idea that incremental code changes are made frequently and consistently. Continuous Integration (CI)-triggered automated build and test stages ensure that code changes submitted into the source are trustworthy.

The 5 Principles of Agile Software Development Methods

Aggregated on: Thu Jan 27 2022 16:34:45 GMT+0000 (Coordinated Universal Time)

Over the years, software development methods have also upgraded parallelly with technological advancements. Agile software development methods are one approach in the current software development trends. Agile methodology breaks up the project into many phases and distributes the workloads across the teams. We prioritize continuous improvement at each stage rather than working on changes at the deployment stage altogether. Progress is constantly updated with the team members during the daily scrum meetings. The examples of agile-based development methods are scrum, Extreme Programming (XP), Feature-Driven Development (FDD), Adaptive Software Development (ASD), Crystal, Dynamic Systems Development (DSD), Lean Software Development, etc. The methods are selected according to the type of product/service to be developed. All these agile methods follow a set of dedicated principles. In this blog, we will focus on five crucial principles of agile methodology. 1. Be Open to Challenges and Changes The agile methodology focuses on being highly responsive to changes at all phases of software development. Our teams must be aware of what is going on in the project at any development phase. The agile method splits the tasks and deliverables into iterations to achieve this high degree of clarity. The iterations must be completed in shorter time frames, usually from a week to four. Ensure that the time frames align with the overall time allocated to the project.

How To Get C++ Speed in Java Serialization

Aggregated on: Thu Jan 27 2022 12:49:45 GMT+0000 (Coordinated Universal Time)

Using Trivially Copyable Objects To Improve Java Serialisation Speeds For any low-latency software, it is vital that the most common operations introduce minimal latency. For example, in trading software, one common and time-sensitive operation is messaging between microservices. To minimize the memory footprint of the communication, all messages are serialized by the sender and deserialized by the receiver. Hence, from a performance perspective, it is vital that the process of serializing/deserializing introduces minimal latency. Read this article and learn more about the low-latency technique leveraging C++ methodology in Java: Trivially Copyable Objects and memcpy. Make common operations a little faster thereby saving a lot of time in aggregate operation. Serialization of Trivially Copyable Objects can be more than five times faster than that of regular Java objects and is supported by Chronicle libraries such as Chronicle Services and other libraries as described in this related article on DZone.

Introduction to Couchbase for Oracle Developers and Experts: Part 3: Data Types

Aggregated on: Thu Jan 27 2022 10:04:45 GMT+0000 (Coordinated Universal Time)

As part of data remodeling, while moving from the relational model to the JSON model, you’ll have to consider the data type mapping. In Oracle, you’ll have to create and declare the types of each column explicitly before you load the data or write queries. In Couchbase, you simply conform to JSON syntax and the data type interpretation is automatic and implicit. Here’s the overview of mappings, conversion, and arithmetic on these data types. Here’s Part 1 and Part 2 of this series. ReModeling: From Relational to Document Model Oracle Couchbase Model Relational, Object-relational JSON model with N1QL (SQL for JSON) Data Types A long list of data types https://docs.couchbase.com/server/current/n1ql/n1ql-language-reference/datatypes.html String Data types CHAR, VARCHAR, VARCHAR2, NCHAR, NVARCHAR, LOONGVARCHAR String, up to 20MB in length. All of the string data in JSON is Unicode. Date and Time Data Types DATE, TIME, TIMESTAMP, all these with TIMEZONE, INTERVAL Date, Time, Timestamp, all these with timezones should be represented in ISO 8601 format and saved as strings. N1QL has extensive functions for formatting, extraction, conversion, and arithmetic.

The One Timeless Benefit of Design Patterns

Aggregated on: Thu Jan 27 2022 00:34:45 GMT+0000 (Coordinated Universal Time)

There’s not much buzz about design patterns these days. They appear to have joined the hall of fame of accepted wisdom, alongside the Silver Bullet, SOLID and DRY. Lately, I had the opportunity to share some thoughts on the importance of good old design patterns with Koen Aerts, CTO of Team Rockstars IT. Here’s the gist of that talk in a more digestible format. Before I start, let me set some boundaries, as people can get doctrinaire about definitions. I refer to the good old bridge, builder, decorator, and factory patterns. Architectural patterns like MVC do not fall into the same category, much fewer paradigms like serverless and microservices (aka SOA the next generation).

The CSS Box Model

Aggregated on: Thu Jan 27 2022 00:34:45 GMT+0000 (Coordinated Universal Time)

The CSS box model is a term thrown around in CSS with very little context, but is probably the most fundamental things you can know in CSS. Simply put, the box model determines, the size, margin, and padding of any object on the page. It also refers to the weird way CSS handles 'inline' and 'block' content. The Box Model In HTML, every element creates a box. Some of these elements, such as span and p are inline, meaning they are in line with text, rather than structural elements of the page.

ER Diagrams vs. ER Models vs. Relational Schemas

Aggregated on: Wed Jan 26 2022 23:49:45 GMT+0000 (Coordinated Universal Time)

Introduction It's crucial to choose the correct model for your data before starting a project. Over the years, developers coined terms to describe the various systems they use to perform this vital planning. This article will explain the differences between three different planning systems: ER models, ER diagrams, and relational schemas. We'll learn important terminology, compare and contrast these three concepts, also look at some examples and considerations for each. ER Models and ER Diagrams "ER model" is short for "entity-relationship model," a high-level data model. As the name suggests, a data model depicts how a database is structured at a logical and visual level. In layman's terms, an ER model defines the elements and their relationship in a specific database. It's like a "blueprint" to your database, providing a simple view of the data.

To develop outstanding websites and applications, you need the correct web framework. Many developers find frameworks like Vue, Meteor, Ruby on Rails, and Meteor extremely productive. Here we have presented the list of most popular web development frameworks in 2022. We will look at their features in detail to help you choose the perfect web framework.

Docker: How to Stop and Remove All Containers at Once

It’s an understatement to say that Docker is a game-changer for systems engineers and developers. You can run almost any application with a single command and customize it for your environment via a consistent container-based interface. But as containers proliferate, controlling them gets more complicated, too. Managing containers from the command line can be painful, but setting up an orchestration tool like Kubernetes or Docker Swarm is overkill for smaller systems. Stopping and removing a container from the command line takes two steps. Stopping and removing two containers is four. And stopping and removing 10 containers is — well, you get the idea. Let’s look at how to make the Docker command line easier to use. We’ll focus on stopping and removing containers. Then, we’ll look at Docker Compose, another tool that makes managing smaller collections of containers easier.

Quantum Duality of API as a Business and a Technology

As an API strategy store project manager who is responsible for the API program, you have to look at both of these two sides and find the balance. It’s really hard to say what the correct balance is because it totally depends on the current landscape, on the business models, as well as on the technology maturity that you have. So you have to analyze it, and then look at the maturity model, and have a proper way of increasing or improving the business models as well as improving your technology stack. What I’m going to do in this article is walk you through the concept of quantum duality of API as a business and API as a technology because a lot of organizations are focusing on API programs, but they are looking at only one aspect of this problem: either the business side or the technology side. However, we need to have a balance. This is where I’m going to discuss and share some of my experience working with different types of enterprises around the globe. The first thing we’ll talk about is the federation and business models around APIs, and then we will move on to how this polyglot and heterogeneous nature affects API development. From the technology side, it will be how you can move to the cloud and leverage cloud-native technologies and how you can modernize the development. All of these four pieces are tied together for a successful API program, so I’m going to discuss these concepts.

Kubernetes is changing the tech space as it becomes increasingly prominent across various industries and environments. Kubernetes can now be found in on-premise data centers, cloud environments, edge solutions, and even space. As a container orchestration system, Kubernetes automatically manages the availability and scalability of your containerized applications. Its architecture consists of various planes that make up what is known as a cluster. This cluster can be implemented (or deployed) in multiple ways, including adopting a CNCF-certified hosted or managed Kubernetes cluster.
