How to Make a REST API Call in Angular

Aggregated on: Mon Feb 21 2022 23:20:02 GMT+0000 (Coordinated Universal Time)

Introduction This article elaborates on the main steps of making a REST API call in the Angular framework. To understand this article, the reader must have a basic understanding of HTTP, HTML, TypeScript, and Angular framework. Further, the reader must have knowledge about creating services and dependency injection in the Angular framework. What Is Angular Service? "A service in Angular acts as a reusable data access point and is written using a Typescript class." In real-world applications, data accessed from external sources is required in multiple components. We need a single, reusable data access point, and service serves this purpose. By defining such processing tasks in an injectable service class, we make those tasks available to any component.

Sustaining Agile Transformation – Our Experience

Aggregated on: Mon Feb 21 2022 22:50:02 GMT+0000 (Coordinated Universal Time)

Introduction Most of the organizations today are moving towards Agile to achieve faster delivery, higher business value, and better quality. In our experience, the average time for organizations to achieve Enterprise Agility is around 2-3 years. Most of the organizations plan only for the transformation and think less about the sustenance. One of the twelve Agile principles emphasizes the importance of sustainable development and the need to maintain a constant pace throughout the cycle. The same principle applies to the organization-level transformation context as well as any change without stability and consistency may not be long-lived. A sustainable agile transformation is one that creates a self-sustaining, continuously learning organization focused on delivering improved business results. It is important for organizations to build a transformation sustenance strategy so that they do not fall back to old ways of working.

Multiple Inheritance in Java

Aggregated on: Mon Feb 21 2022 19:20:02 GMT+0000 (Coordinated Universal Time)

Ever since Java 8 introduced default interface methods, I felt there had to be a way to use it for multiple inheritance. I have never needed it, but I was bored for a bit today, so decided to try the following idea: Create a non-public class XData to hold the fields the interface needs to work with, and a public interface X in the same X.java source file The interface has one virtual method getXData() that returns the XData instance The remaining interface methods are default methods that call getXData() to read and write the fields as necessary to perform some useful operations. Create another interface Y and class YDatain the same pattern Create a class XY that implements both interfaces X and Y The class XY has XData and YData fields, which are returned by getXData() and getYData(). These are the only two interface methods XY is required to implement. I didn't bother in my example, but XY would have to decide how to implement the Object methods hashCode, equals, and toString. These methods cannot be implemented by interfaces (but they could be implemented in XData and YData classes if desired) The end result is the XY class is an instance of both X and Y interfaces, and inherits the encapsulated behaviors of both X and Y default methods - multiple inheritance by any reasonable measure.

One of my favorite exercises from my Professional Scrum Product Owner classes is how to best sabotage a Product Owner as a member of the middle management. The exercise rules are simple: You’re not allowed to use any form of illegal activity. So, outsourcing the task to a bunch of outlaws is out of the question. Instead, you are only allowed to use practices that are culturally acceptable within your organization. Read on and learn more on how to best sabotage a Product Owner from the exercise results of more than twenty PSPO classes. (I edited the suggestions for better readability.)

SSDL at a Glance

Aggregated on: Mon Feb 21 2022 15:35:02 GMT+0000 (Coordinated Universal Time)

Introduction The Secure Software Design Lifecycle (SSDL) is the infusion of security with each step of software design, from architecture to end of life. By doing so we protect our customers from threats and reduce our risk and attack surface. There are no specific tools or frameworks mentioned in this article. You should choose the ones that work best for your context, based on compliance needs, cost, and labor. The Software Lifecycle The software design lifecycle (SDLC) comprises multiple steps. For the purpose of this article we’ll settle on the following definition of the SDLC:

Nginx + Node.JS: Perform Identification and Authentication

Aggregated on: Mon Feb 21 2022 15:35:02 GMT+0000 (Coordinated Universal Time)

System authorization is one of the key parts. You can use some powerful solutions, such as Firebase, or one of the many good libraries. If you want to reduce the number of dependencies or you need some self-education, you can write something of your own. This is how over time, after several iterations, a solution based on Nginx was developed. Everything described is a very special case of the approach used, in the sense that there are some conditions in which it was required to create a solution, and this solution is good only in those particular conditions.

Future JavaScript: Records and Tuples

Aggregated on: Mon Feb 21 2022 15:35:02 GMT+0000 (Coordinated Universal Time)

Records and Tuples are an upcoming feature for JavaScript, which may be familiar if you have used other languages. They are very similar to Arrays and Objects, the key difference being that they are immutable, meaning they can't be updated or changed. They give us a brand new primitive type in JavaScript, and let us do a lot of things we couldn't previously do, including comparing objects and arrays by value, rather than identity. In this article, we'll cover how they work, and how you can use them today. Support for Records and Tuples Currently, records and tuples are a stage 2 proposal for JavaScript. Broadly speaking, this means that they are relatively stable, but not implemented as a standard spec. As such, major browsers and backend JavaScript like Node.JS do not implement them. You can, however, use them, if you have Babel, by using this polyfill.

Using Kong Ingress Controller with Spring Boot Services

Aggregated on: Mon Feb 21 2022 12:35:01 GMT+0000 (Coordinated Universal Time)

Since 2003, I have used IntelliJ as my primary tool for developing applications and services. Nineteen years ago, I was impressed both by the small amount of RAM required to use the IDE and the refactoring abilities included with the 1.x release. Developing in Java does not require me to use the IntelliJ IDEA product. Other developers on my current project use Eclipse or VS Code, but these tools are not required. When you can write your components, services, and applications with a simple text editor and terminal session, you’ll end up with the same compiled Java code.

Avoiding Stringly-Typed in Kotlin

Aggregated on: Mon Feb 21 2022 12:35:01 GMT+0000 (Coordinated Universal Time)

A couple of years ago, I developed an application in Kotlin based on Camunda BPMN to help me manage my conference submission workflow. It tracks my submissions in Trello and synchronizes them on Google Calendar and in a Google Sheet. Google Calendar offers a REST API. As REST APIs go, it's cluttered with String everywhere. Here's an excerpt of the code: Kotlin fun execute(color: String, availability: String) { findCalendarEntry(client, google, execution.conference)?.let { it.colorId = color // 1 it.transparency = availability // 2 client.events() .update(google.calendarId, it.id, it).execute() } }

What's New With ActiveMQ v5.16.4

Aggregated on: Mon Feb 21 2022 00:05:01 GMT+0000 (Coordinated Universal Time)

Client-Side Max Message Size Detection In previous versions of ActiveMQ, an exception case that limited the ability for developers to code fully self-healing message flows was when a client sends a message that exceeds the broker's max message size limit. ActiveMQ brokers detect this scenario and immediately close the connection to prevent any negative impact to the broker by misbehaving clients. While this approach is great for protecting the broker, it does not provide any signaling to the client as to how to respond. Before 5.16.4, clients configured with failover would reconnect and retry messages that were too large, causing sent messages to run in an infinite loop. In 5.16.4, the client library detects the scenario and throws a JMSException with Error Code (41300). Also, there is now a MaxFrameSizeExceeded exception that is accessible as the linked exception off the JMSException. This allows clients to cleanly detect this scenario, take corrective action, and continue to process the next message.

Harmful Misconceptions in Software Testing

Aggregated on: Sat Feb 19 2022 17:35:00 GMT+0000 (Coordinated Universal Time)

In 1870, the German chemist Erich von Wolf was investigating the amount of iron in spinach. When writing down his findings in his notebook, he misplaced a decimal point, changing the iron content in spinach ten times more than in reality. While Mr. von Wolf found out that there are just 3.5 milligrams of iron in a 100g serving of spinach, the published number became 35 milligrams thanks to his mistake. This caused the well-known misconception that iron is exceptionally high in spinach, which makes the body stronger. Though Mr. von Wolf's error was detected and fixed 67 years later when someone re-checked his results, spinach is still popularly thought to be one of the most iron-rich vegetables, probably due to the popular cartoon character Popeye.

You decided to make an app that works with SVG. Encouraged by the enthusiasm, you collected libraries and successfully made the application. But suddenly you find that the app is sending strange network requests. And data is leaking from the host machine. How so? In today's world, you can have a library for every occasion. So, let's not reinvent the wheel for our application and take a ready-made solution. For example, the SVG.NET library. The source code of the project is available on GitHub. SVG.NET is distributed as a NuGet package, which comes in handy if you want to add the library to the project. By the way, according to the project's page in NuGet Gallery, the library has 2.5 million downloads — impressive!

Why Do We Encourage Poor Coding Patterns?

Aggregated on: Sat Feb 19 2022 16:35:00 GMT+0000 (Coordinated Universal Time)

For what feels like an eternity at this point, we’ve discussed “shifting left” in the SDLC, taking into account security best practices from the start of software development. DevSecOps was a great leap forward, in no small part because of the emphasis on shared responsibility for security, and the power of a security-aware developer to thwart common vulnerabilities as they write code. We have also known — again, for eons — that the type of secure code training chosen to engage and upskill developers makes all the difference. Low-effort solutions motivated solely by regulatory compliance do not build up the bright security minds of the future, and most security awareness professionals have worked that out. Dynamic, contextually relevant learning is best, but it’s critical that the nuances within are understood.

How To Embed Data Protection Principles in the Application Development Process

The pace of digitization over the past two years has accelerated due to organizational needs driven by the ongoing pandemic. And that has meant that there's an ever-increasing flow of data now passing through digital channels that nobody anticipated. And for developers, it has spotlighted the importance of implementing clear data protection standards in everything they do. But for developers who've never written software that requires a careful approach to data protection, it's not always obvious how to convert best practices into development standards. To help those who lack experience with embedding data protection standards into their development process, here's a guide to what they need to do.

5 Best Practices for Succeeding at Developer-First Application Security

Aggregated on: Fri Feb 18 2022 18:35:00 GMT+0000 (Coordinated Universal Time)

Advances in developer tools, containers, code repositories, and more enable developer teams to deliver software at an unprecedented pace. However, application security teams are often understaffed, underfunded, and laboring to keep pace with software development. One demonstrated strategy that helps AppSec teams keep up and even provides them time for high-value security tasks is to shift security left in the development cycle. Creating a developer-first approach to security, or in other words, shifting security left requires that developers become accountable for producing secure code. Since security is not the typical developer's area of expertise, application security engineers assume the role of providing oversight and guidance needed to enable developers to succeed.

Basic Google BigQuery Operations With a Salesforce Sync Demo in Mule 4

Aggregated on: Fri Feb 18 2022 17:50:00 GMT+0000 (Coordinated Universal Time)

If we think about data storage, the first thing that comes to our mind is a regular database. This can be any of the most popular ones, like MySQL, SQL Server, Postgres, Vertica, etc., but I noticed not too many have interacted with one of the services Google provides with the same purpose: Google BigQuery. Maybe it is because of the pricing, but in the end, many companies are moving to cloud services and this service seems to be a great fit for them. In this post, I will demonstrate in a few steps how we can make a sync job that allows us to describe a Salesforce instance and use a few objects to create a full schema of those objects (tables) into a Google BigQuery dataset. Then with the schema created, we will be able to push some data into BigQuery from Salesforce and see it in our Google Cloud Console project.

In recent years, DevOps has established itself as a formidable force in the software world. By bridging the gap between development and IT operations teams, DevOps has brought speed, efficiency, and quality to software development. It enabled IT businesses to adopt agile software delivery methodologies like Continuous Integration and Continuous Delivery (CI/CD). However, despite gaining universal popularity, the road to successful DevOps adoption remained bumpy. Many organizations struggle to implement optimal automation across the software development lifecycle (SDLC), from build, integration, and testing to delivery and deployment. Consequently, harnessing the full potential of the CI/CD pipeline remained elusive. At this juncture, Jenkins has emerged as an indispensable tool to help DevOps teams achieve automation goals.

Cloud Migration Manual: The Adjustment to SaaS Model

Aggregated on: Fri Feb 18 2022 14:05:00 GMT+0000 (Coordinated Universal Time)

The cloud-based SaaS model eliminates the need to build, set up, and manage the system, allowing users to just purchase the desired program for a certain length of time. And to migrate to the cloud you need to set up a roadmap, prepare to change app architecture, pick up a SaaS hosting provider, and lastly delineate the data migration process. Before the gaining growth of SaaS software popularity within the development, IT solutions were pretty obvious: businesses had on-premises applications, which operated on particular servers with a certain volume and other limitations. And developing ones, companies went along with the high fees on maintenance, expenses on manual labor, as well as challenges regarding updating.

Kafka vs Chronicle for Microservices

Aggregated on: Fri Feb 18 2022 13:35:00 GMT+0000 (Coordinated Universal Time)

Apache Kafka is a common choice for inter-service communication. Kafka facilitates the parallel processing of messages and is a good choice for log aggregation. Kafka also declares to be low latency, high throughput. However, is Kafka fast enough for many microservices applications?When I wrote Open Source Chronicle Queue my aim was to develop a messaging framework with microsecond latencies. In this article, I will describe why Kafka does not scale in terms of throughput as easily as Chronicle Queue for microservices applications. Visualizing Delay as a Distance In order to illustrate the difference, let me start with an analogy. Light travels through optic fiber and copper at about two-thirds the speed of light in a vacuum, so to appreciate very short delays, they can be visualized as the distance a signal can travel in the time. This can really matter when you have machines in different data centers.

Articles Covering Topics on CockroachDB and Kerberos I find the topic of Kerberos very interesting and my colleagues commonly refer to me for help with this complex topic. I am by no means an expert at Kerberos, I am however familiar enough with it to be dangerous. That said, I've written multiple articles on the topic which you may find below: CockroachDB With MIT Kerberos CockroachDB With Active Directory CockroachDB With MIT Kerberos and Docker Compose Executing CockroachDB table import via GSSAPI CockroachDB With SQLAlchemy and MIT Kerberos CockroachDB With MIT Kerberos Cert User Authentication CockroachDB with Django and MIT Kerberos CockroachDB With Kerberos and Custom Service Principal Name (SPN) Simplifying CockroachDB Kerberos Architecture With a Load Balancer CockroachDB With MIT Kerberos Using a Native Client CockroachDB With Mixed Kerberos and Certificates Authentication Motivation Systemd has become a standard approach for deploying Linux services. We have documentation to deploy CockroachDB via systemd, however, we do not have steps documented to deploy CockroachDB with GSSAPI and systemd. This tutorial attempts to bridge that gap.
