How To Use Docker Volume To Build Angular Application With Jenkins Pipeline

Aggregated on: Fri Aug 11 2023 23:31:26 GMT+0000 (Coordinated Universal Time)

In the realm of Docker, a volume refers to a durable storage destination that exists independently of the container. Volumes prove invaluable for preserving data that should endure beyond the container's lifecycle, even if the container is halted or deleted. The volume will be created when the container is built, and it can be accessed and modified by processes running inside the container. Utilizing Volumes in a Docker Container Offers Several Compelling Advantages: Data Persistence: When you have critical data that must endure beyond a container's lifecycle, volumes provide the ideal solution. Storing items like database files or application logs in a volume ensures their preservation even if the container is halted or deleted. Sharing Data Among Containers: Volumes facilitate seamless data sharing among multiple containers. By leveraging a volume, you allow different containers to access the same data, making it convenient for storing shared configuration files or data utilized by multiple containers. Streamlining Data Management: Volumes contribute to efficient data management by decoupling data from the container itself. For instance, you can employ a volume to store data generated by the container and then easily access that data by mounting the volume on a host system, simplifying data handling and manipulation. In Jenkins pipelines, Docker volumes offer a convenient solution for building Angular projects without requiring the installation of the Angular library on the Jenkins node machine.

How DNS Checking Helps Developers

As the digital landscape continues to evolve, the role of developers has become even more crucial. They are responsible for building and maintaining websites and applications that are not only functional but also reliable and secure. One crucial aspect of website and application performance is the Domain Name System (DNS). In this article, we will explore how DNS checking can greatly benefit developers in ensuring smooth and efficient operations. What Is DNS Checking? DNS checking, also known as DNS validation, refers to the process of verifying and analyzing the Domain Name System to ensure that it is functioning correctly. The DNS is essentially a decentralized system that translates domain names (e.g., www.example.com) into IP addresses (e.g., 192.0.2.1) to locate web servers and other resources on the internet.

Exploring Path-Finding Algorithms for Wall-E

Aggregated on: Fri Aug 11 2023 20:31:26 GMT+0000 (Coordinated Universal Time)

The Story Behind A few years ago, Yandex organized a contest called Robots Couriers with an enticing prize: a ticket to a closed self-driving conference for professionals. The contest resembled a game, with participants tasked with finding optimal routes on a map and optimizing delivery using robotic couriers. As I delved into the topic, I discovered that despite route finding being a solved problem, it continued to be of interest to the professional game development community. Between 2010 and 2020, engineers made significant optimizations to the A* algorithm, particularly beneficial for AAA games with massive maps. Reading articles and research papers on these optimizations was an exciting experience.

Can Redis Be Used as a Relational Database?

Aggregated on: Fri Aug 11 2023 20:16:26 GMT+0000 (Coordinated Universal Time)

Let's start with the question, "How do you use Redis?" I'm sure most use it as a cache for the service. I hope you know that it can do more than just that. Recently, I spoke at a conference with a report on how we moved part of the data to Redis and requests fly to it in the first place. Now I want to tell you not about how we applied it, but about the fact that when working with Spring and its abstractions, you may not immediately notice the substitution. Let's try to write a small Spring app that will use two PostgreSQL and Redis databases. I want to note that we will store in the databases not some kind of flat object, but a full-fledged object from a relational database with nested fields (inner join). To do this, we need plugins that need to be installed in Redis such as RedisJSON and RediSearch. The first allows us to store our object in JSON format, and the second allows us to search by any field of our object, even nested fields.

Part 1: Integrating Debezium Server and Memphis.dev for Streaming Change Data Capture (CDC) Events

Aggregated on: Fri Aug 11 2023 01:31:26 GMT+0000 (Coordinated Universal Time)

This is part one of a series of blog posts on building a modern event-driven system using Memphis.dev. Change data capture (CDC) is an architectural pattern that turns databases into sources for event-driven architectures. Frequently, CDC is implemented on top of built-in replication support. Changes to data (e.g., caused by INSERT, UPDATE, and DELETE statements) are recorded as atomic units and appended to a replication log for transmission to replicas. CDC software copies the events from the replica logs to streaming infrastructure for processing by downstream components.

Evolving Software Like an Orchardist

Aggregated on: Fri Aug 11 2023 01:31:26 GMT+0000 (Coordinated Universal Time)

Software systems are usually larger, overgrown structures that developers need to bring back into shape after some time. However, creating an overview of the sprawling conglomerate of software components is challenging, let alone developing a clear plan for moving on. This blog post uses analogies from pruning apple trees to show developers how to evolve their software systems using a value-based approach.Everyone is happy if one has a fruitful apple tree in the garden. The blossoms in spring are a feast for the eyes, and the apples you’ve harvested yourself in late summer taste the best! But after some years, when the apple tree gets older, it also gets weaker. The apples don’t shine in red anymore. Some of them are still green or already moldy. It seems that the apple tree is ill somehow. The reason is usually that the tree is simply too overgrown. Many water shoots weaken the vitality of the tree, the strength goes into the leaves, and there is nothing left anymore for the apples. But the solution is clear: the apple tree must become more vital again! There are many ways you can do this, from removing the water shoots to cutting off entire branches or replanting the whole apple tree. You can also do crazy things, like leaving some bigger branches to attach a swing to it. It all depends on the individual needs one has! Sure, a pruned apple tree looks a bit horrible at first when you see it after the pruning. But it positively affects it, allowing it to recover and build strength for the spring. You will be rewarded with a rich harvest in the summer and again enjoy a vital apple tree with delicious apples! Now at the very latest, you’re asking yourself: What the fiddlestick does this have to do with software systems? We can compare a software system with an apple tree (yes, it was predictable that this blog post would take this direction, but bear with me, it’s about to get more interesting!) A software system consists of many components, often tens or even hundreds of tiny little parts at specific places within a system (or a system of systems). Those components are, of course, somehow interconnected and form a tree-like structure if you look at a system from a certain point of view. (OK, I know, I know. In reality, this tree looks a little bit more complex, so let’s say there are many more connections between those components. Are you happy now? Yes? OK, then we can move on.) To make it even better, we, as software developers, like to have a different/special/nerdy view on trees. We like our trees upside down (for whatever reason). So let’s rotate that tree (for god’s sake. But it’s also better for me to get my points across later.) Of course, the elephant in the room is: What are the connections between the components? It could be anything like data flow, protocols, team dependencies and many more! But let’s keep it simple. Imagine you have a user of your system at the top. She needs something to be accomplished. The components below fulfill those needs but also have needs. The components below fulfill those needs but also have needs. The components … I think it’s clear what I want to say: We build a chain of needs from top to bottom. This view on our software system also gives us an additional hint regarding a component’s perceived value. Because the user at the top sees (more or less) the components at the top (e.g., by interacting with them directly like an app), she understands that those components deliver the things she wants to accomplish. Thus those components are especially valuable to her. With this approach, we get our tree of components similar to an apple tree! Similarly, we can discuss possible actions about how we want to evolve our software system. There are plenty of those actions we can think about (look at the end of this blog post for more information). But there is more: we can also see where it is easy to get our software system back in shape. Especially the components that a user can directly recognize are the ones that you can easily get started with. If there are problems in or with those components, business people will give us a lot of money to fix them. But it’s unfortunate when a component far from the user’s perception is problematic. A user (or product manager) cannot see this component directly. Therefore, it is unclear why to invest money here. But with our tree, we have a good chance of convincing the business even for those components. We connect the lower components with more visible components of the top by showing the advantageous features of the lower components and how they relate to the upper. By jumping over unnecessary components, we get those lower components in the “awareness zone” of users and product managers because those changes suddenly add value for them too! If we have found an interesting part of our software system (aka path(s) with components) to evolve, we can think about possible next steps and create and discuss that on a separate plan. This dedicated branch focuses on a specific situation with relevant users, their individual needs, and components that fulfill those needs. Subsequently, we add the next steps that show which components we want to evolve to the plan. This gives us a roadmap-like picture that we can use to communicate our small plan for the value-based evolution of our software system to business people. After we’ve finished several modernization plans like this, we get a nicely reshaped software system that can thrive, grow, … … and provide many new fruits because of our work!

JMS and Kafka Compared

Aggregated on: Thu Aug 10 2023 21:31:26 GMT+0000 (Coordinated Universal Time)

In this article, we explore the comparison between JMS (Java Message Service) and Kafka, two widely used messaging systems in modern applications. While both serve the purpose of enabling efficient communication between applications, they differ significantly in their design, features, and use cases. In today's distributed architectures, where applications and services are spread across multiple nodes, messaging systems serve as the backbone for inter-application communication. They enable asynchronous and decoupled communication, allowing different components to exchange data reliably without being tightly coupled. By utilizing messaging systems, developers can build scalable, fault-tolerant, and loosely-coupled architectures that are flexible and resilient to failures.

Delving Into the Performance Features of Logical Replication in PostgreSQL 16

Aggregated on: Thu Aug 10 2023 20:31:26 GMT+0000 (Coordinated Universal Time)

In my last article, I examined the concept of replication methods in PostgreSQL and provided an overview of the main characteristics of logical replication incorporated into PostgreSQL 16. Now, I am going to explore the performance features associated with logical replication, showcase the steps for observing these features in real time, and share the outcomes of performance benchmarking. I want to spotlight two specific features of PostgreSQL 16 — parallel apply and binary copy. The parallel apply feature extends the capability to utilize parallel background workers at the subscriber node to facilitate the application of changes in large ongoing transactions. The specification of the number of parallel workers that should be engaged for assimilating changes from the publisher is determined by max_parallel_apply_workers_per_subscription. The binary copy, the second performance feature, permits logical replication to conduct the initial data copy in a binary format. This significantly enhances performance, particularly when copying tables containing binary columns.

Parsing Complex JSON in Kafka Source Using Apache SeaTunnel

Aggregated on: Thu Aug 10 2023 20:16:26 GMT+0000 (Coordinated Universal Time)

Version Information: SeaTunnel: apache-seatunnel-2.3.2-SNAPSHOT Engines: Flink 1.16.2 Zeta: Consistent with SeaTunnel Introduction Recently, we took over a data integration project where the upstream data was delivered to Kafka. Initially, we chose the SpringBoot+Flink approach to process the incoming data (referred to as Solution 1 below). However, after facing efficiency issues in the production environment, we turned our attention to the open-source project SeaTunnel. We discovered that SeaTunnel supports Kafka as a source and started exploring and testing it. In our development environment, we experimented with over 5 million records and achieved an efficiency of around 10,000 records per second. Consequently, we abandoned Solution 1 and adopted SeaTunnel for integrated data processing (Solution 2 below). During our exploration of SeaTunnel, we identified two methods. Method 2, compared to Method 1, offers a more comprehensive solution that handles various scenarios without concerns about data misalignment caused by unexpected characters within field values.

Custom Software vs. Readymade Software

Aggregated on: Thu Aug 10 2023 19:46:26 GMT+0000 (Coordinated Universal Time)

In the realm of software development, organizations often face the decision of whether to invest in custom software or opt for ready-made software solutions to address their specific needs. Both approaches have their advantages and disadvantages, and the choice depends on various factors such as budget, requirements, timeline, and long-term objectives. What Is Software Development Lifecycle (SDLC)? SDLC, which stands for Software Development Life Cycle, is a structured and systematic approach used by software developers to design, develop, test, deploy, and maintain software applications or systems. It is a framework that guides the entire process from the initial idea and concept through to the final product's retirement. The primary goal of the SDLC is to ensure the creation of high-quality software that meets the user's requirements and is delivered on time and within budget.

Request-Level Authentication and Authorization With Istio and Keycloak

Aggregated on: Thu Aug 10 2023 19:31:26 GMT+0000 (Coordinated Universal Time)

Kubernetes has made it easier to manage containerized microservices at scale. However, you get a limited set of security features with Kubernetes. A key component of application security is the prevention of unauthorized access. Standards-based identity and access management (IAM) for user authentication, such as SAML, WS-Fed, or the OpenID Connect/OAuth2 standards, have to be used to ensure secure access to the application. Multi-factor authentication (MFA) can also be implemented as an additional security measure. Yet there is no native way to implement these security features in Kubernetes. Even crucial security aspects like request-level authentication and authorization are not supported out of the box.

Understanding Security Vulnerabilities: A First Step in Preventing Attacks

Aggregated on: Thu Aug 10 2023 18:46:26 GMT+0000 (Coordinated Universal Time)

When I was a teenager, our local telephone company introduced a new service — the premium phone calls (AKA 1-900 numbers). The fun part was that we discovered a workaround to these charges by dialing the sequential local numbers, which these 1-900 numbers would redirect to. If the "support number" for the 1-900 was 555-555, we would dial every number between 555-455 and 555-655 until we hit the jackpot... Hours were spent dialing these numbers, leading us to make numerous calls for free. This attack is still prevalent today, and it's called Insecure Direct Object References (IDOR).

I sometimes surprise fellow technologists when I tell them that a successful digital payments company we built runs on FreeBSD. It’s not that they haven’t heard of FreeBSD — the open-source operating system turns 30 this year, after all. Rather, it’s that they hadn’t previously thought of FreeBSD as an enterprise OS. But that’s exactly what it is and how we use it: FreeBSD is a critical enterprise-grade OS that is on par with —and in some ways surpasses — other operating systems when working in enterprise environments.

Ordering in Event-Sourced Systems

Aggregated on: Thu Aug 10 2023 18:16:26 GMT+0000 (Coordinated Universal Time)

In a utopian world, Event Store will write events to the disk in the same order they have happened in real life. However, computers are not so good at observing things by themselves (yet); we (still) must tell them what to do. Hence, we must provide a way to deterministically order events inside the Event Store. A naive approach would be to attach a timestamp to each and every event and use it for ordering. The reason for its naiveness lies in the difficulty of synchronizing clocks across different machines in a distributed system. As a consequence, we mustn't rely on timestamps for ordering.

Revolutionizing IT: Ultraviolet’s Innovative Approach to Developer Efficiency

Aggregated on: Thu Aug 10 2023 18:16:26 GMT+0000 (Coordinated Universal Time)

Modern software demands speed, security, and scale. Ultraviolet is meeting these needs through a developer-focused approach that multiplies productivity while reducing complexity. At BlackHat 2023, Ultraviolet CTO Jake Groth outlined how the company leverages microservices, “as code” methodologies, and developer-created content to propel developer velocity. Microservices — a modular architecture of discrete, independent components — is central to Ultraviolet’s strategy. This contrasts with monolithic apps where developers wrestled with massive, convoluted codebases jammed with interdependent functions. With microservices, developers can concentrate on particular capabilities and roles, playing to their specialized strengths.

Monitoring vs. Observability in 2023: An Honest Take

Aggregated on: Thu Aug 10 2023 17:16:26 GMT+0000 (Coordinated Universal Time)

If you're running a software system, you need to know what’s happening with it: how it’s performing, whether it’s running as expected, and whether any issues need your attention. And once you spot an issue, you need information so you can troubleshoot. A plethora of tools promises to help with this, from monitoring, APMs, Observability, and everything in between. This has resulted in something of a turf war in the area of observability, where monitoring vendors claims they also do observability, while “observability-first” players disagree and accuse them of observability-washing.
