Remote Debugging Cloud Foundry Apps
Context
While debugging Java applications in an IDE like IntelliJ Idea is straightforward, it involves slightly more effort to debug a remotely running app. While debugging a remotely running app in production is generally not a good idea, the ability to remote debug apps in lower environments, like integration testing, may be useful.
Cloud Foundry is a platform that allows you to deploy and run your workloads easily and intuitively. IntelliJ Idea is a popular IDE, especially for Java developers.

Building a Simple Front-End for Your ArangoDB Datasource
A major pain point around building apps is designing the UI elements. Fortunately, with Appsmith, you create a custom frontend in minutes. Connecting datasources with Appsmith takes a few minutes, and you can easily build tools on top of the database of your choice. For example, you can build admin panels to manage product catalogs, read content data from your database and use that to populate your e-commerce website, and then write more data and update your existing orders in the database. The possibilities are countless.
In this blog, I will teach you how to build a frontend that can connect to ArangoDB as a datasource.

How To Use Watchers in Vue
In any web application, it's normal to have input data that alters a page. For example, a user may update their username, or submit a post. In vue, we can watch for these changes using watchers. Watchers allow us to check on a specific data element or prop and see if it's been altered in any way.
If you are brand new to Vue, get started with our guide on making your first Vue app here, before diving into watchers.

DataWeave Tip #8: The write Function
Originally published February 26, 2019
Recently I have been working on a really simple case. When an HTTP server returned an error and a non-empty body, I needed to embed this body into an error structure. Although this is a simple case, I got a problem with implementing it in Mule 4. In the previous Mule edition, it was a little bit simpler. So let's see what it is all about.
Case
First, we have a look at the case that I have to implement. I have a mule application that is calling an external HTTP server via an HTTP request component. When the server responds with an error like 4xx, 5xx, and the returned body will is not empty, we would like to forward that response to the calling application.

Why GitOps Is So Important to Businesses Today
Why Gitops Matters for Business Success
At a recent event, Weaveworks’ Chief Operating Officer Steve George explained exactly why GitOps is so important to businesses. It’s an important point to make because, as a fast-growing technological approach, GitOps is usually discussed from the perspective of the technologist. As a result, most practitioners are now familiar with the concept of GitOps, if not the practical details. In the boardroom, however, knowledge levels remain low – despite the fact that a significant body of data now suggests that GitOps delivers measurable business value.

How To Reuse Your Ansible Roles To Build Docker Images With Packer
In this article, I will show you how to reuse your Ansible roles to build Docker images using Packer.
If you are like me, you have probably used Ansible for a while. You probably have Ansible roles that you use to install and manage software on-premise and VM. Now you want to reuse those roles to build your own custom Docker images to use for development, testing, or production.
This is possible and very useful with minor changes to the Ansible roles. In fact, with Docker, you start with a very minimalistic environment and you can't take for granted some components that you will find preinstalled on major Linux distros.

Multiple Inheritance in Java
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
XDatato hold the fields the interface needs to work with, and a public interfaceXin the sameX.javasource file - The interface has one virtual method
getXData()that returns theXDatainstance - 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
Yand classYDatain the same pattern - Create a class
XYthat implements both interfacesXandY - The class
XYhasXDataandYDatafields, which are returned bygetXData()andgetYData(). These are the only two interface methodsXYis required to implement. - I didn't bother in my example, but
XYwould have to decide how to implement the Object methodshashCode,equals, andtoString. These methods cannot be implemented by interfaces (but they could be implemented inXDataandYDataclasses 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.

How to Use Postman to Build a Mock Server That Mimics the Marqeta Core API?
The Marqeta Core API lets you build web applications for custom payment card programs with the Marqeta platform. While SDKs for the Core API are available for Python and Ruby, you can always use the developer sandbox and the Core API Explorer to work with the API, regardless of the language you use to develop your application.
For faster prototype development, however, you might find it useful to build an API mock server. In this post, we'll work through how to use Postman to build a mock server that mimics the Marqeta Core API. We'll demonstrate how to create a new collection in Postman, save responses from live requests to the sandbox, and then create a mock server and send our test requests.

The Top SIEM Challenges Modern Security Practitioners Face Today
In many ways, the tools security professionals have at their disposal have not kept up with the seismic changes in IT infrastructure and workloads brought about by the cloud. For example, most Security Information and Event Management (SIEM) platforms are still based on decades-old technology and architectures.
The deficiencies in traditional SIEM solutions are common knowledge throughout the industry, at least anecdotally, but I wanted to see actual data. To explore the firsthand experiences of security practitioners, my company, Panther Labs, commissioned an independent study to understand how well legacy SIEMs meet the needs of security teams today.

Win Your War Against Hackers and Secure Your Network
"Security is always going to be a cat and mouse game because there'll be people out there that are hunting for the zero day award, you have people that don't have configuration management, don't have vulnerability management, don't have patch management." - Kevin Mitnick (American Businessman)
Work culture has changed a lot recently. The ability to work from anywhere and at any time has become comfortable for employees, which in turn has brightened up things for hackers too. These days, sites are being bombarded by hack attacks from groups of hackers who later claim responsibility for the incident and make demands. There are a few pain points where hackers start their games.

8 Types of Functional Testing
Functional and non-functional testing are the two types of software testing. There are various types of functional testing, that are as below:
- Unit Testing
- Integration Testing
- System Testing
- Regression Testing
- Smoke Testing
- Sanity Testing
- Acceptance Testing
- User Acceptance Testing
Brief Description of Functional Testing Types
Unit Testing
Unit testing ensures that every piece of code written in a segment produces the best results. Developers just look at the interface and the determination for a part during unit testing. It provides documentation of code progression because each unit of code is thoroughly tested before moving on to the next.

The Database Connection as a Leverage Point
Most databases are accessed over a network connection. We tend to think of these connections as an opaque tube between the database client and the database server: whatever happens in these tubes is mysterious, and there is nothing we can do about it. I'd like to show you how these connections can in fact be used to augment and improve your information systems.
By routing these database connections through a smart database proxy, we can observe, control and potentially modify the requests and responses going back and forth. This gives us a powerful leverage point:

Cloud Systems (Part 3): Deploying to Amazon ECS
Cloud engineering is taking over software development. In a lot of ways, this is great; it allows us to build and deploy more complicated applications with less difficulty, and maintaining those applications becomes less troublesome too. We can release smaller updates more quickly than ever, ensuring that we can stay on top of feature requests and security issues. That said, the rise of cloud engineering has also introduced a lot of complexity in the form of dozens of services even within just one cloud provider. Figuring out where to start can be tough, so let’s take a practical tour! In this series, I’ll walk you through building a personal website and deploying it using modern cloud engineering practices.
Elastic Container Service
In the previous tutorial, we extended our personal website to use the Flask web framework, add server-side routing, and package everything up into a Docker container. It’s still only running locally, though, and we want to deploy it. To do that, today we’ll be learning to use Pulumi to deploy to Amazon’s Elastic Container Service. If you completed part two of this series, we’ll be picking up right where we left off. If you’re just now joining me, you can get the completed code by forking and cloning this repository.

Low-Code: Aging Like Wine
A couple of weeks ago someone roughly commented on my YouTube channel, writing: "No-Code is a hoax and Low-Code a lie." I deleted the comment, not as much because I wanted to censor him, but more so because I was, quite frankly, a bit embarrassed for the commenter. I didn't want to put him into a position where he'd be forced to defend his incorrect assessment of something of such importance to the future.
Five years ago, the commenter might have been correct. However, today almost 50% of all companies developing software have already delivered projects using low-code and no-code frameworks and platforms, and roughly half of them have good experiences with such platforms. So either 50% of the world is wrong, or the commenter was wrong.

7 Alternatives to Using Segment
What Is a CDP (Customer Data Platform)?
CDPs have risen up as one of the best solutions to tackle the challenge of data accessibility. Strictly speaking, CDPs collect and consolidate data from various sources and send that information to different target destinations (i.e. marketing tools and sales tools). The purpose of a CDP is to aggregate the information from various data sources and combine it together to create a single 360-degree view of the customer.
In addition to this, they also provide an additional activation layer to enable marketing automation. This is because CDPs were created to analyze user behavior and personalize their experiences. Every company has data, so CDPs are useful for both B2C companies and B2B companies.

AI Biometric Authentication for Enterprise Security
Introduction
Biometric authentication technology has been an important industry trend for years, especially in 2021 due to the latest AI innovations available on the market. According to IBM, 20% of breaches are caused by compromised credentials. Worse, it can take an average of 287 days to identify and respond to a data breach.
AI-based security is increasing in usage and will be necessary to remain competitive in any industry. IBM reports that as of 2021, 25% of businesses have completed deployment of AI-based security, while 40% are partially deployed. The remaining 35% have not begun this process, and if your business falls into this category you may be placing your clients at great risk for dangerous data breaches. Investing in AI-based security can save a business up to $3.81 million in 2021.

It often surprises me that, sometimes, tweaking "how" certain things are done, can totally revolutionize "why" they're being done. Methodology, in itself, seeks to re-imagine the meaning.

In our day-to-day, and mainly, in the positions of full remote work, the dedicated time to achieve our tasks and objectives is covered with squalls of meetings (clients, troubleshooting, at a company or team level, dependencies with other people, etc.), and we forget some important factors such as:
- Communication and relationship: Of every monthly and weekly meeting; What percentage do I dedicate to strengthening my relationship with the team to get to know them better and know how they are doing, what motivates them, what concerns them, their hobbies, etc?
- Target: What is the purpose of the meeting? Personal to connect and build relationships with my colleagues or for work purposes? I have a 30-minute meeting to agree on estimates and 15 minutes have been for off-topic discussions.
- Time value: Is the meeting necessary or can the goal of collaborating asynchronously be met? I attended the meeting but, did I have something to contribute or did I learn something that will help me in the future?
In this article, we will focus on the communication side, in which, besides strengthening, we will get feedback that will allow us to improve personally and as a team to also offer a better service and a better quality.

Role of Artificial Intelligence for Government
Introduction
For the last 20 years, the research on artificial intelligence has been very aggressive, which has resulted in great innovations. Big data, robotics, medical research, and autonomous vehicles are some of the applications that emerged from AI development.
Government interest in AI has picked up in recent years as many government departments started to invest in AI in the form of pilot programs for various AI-based applications. AI adoption acts as a lever for transformational change in the way government services are conceived, designed, delivered, and consumed. It helps the government to provide integrated services to its citizens through the seamless flow of information across government departments. In addition, the adoption of AI helps in redesigning government processes, frees up staff, increases productivity, and improves citizen interactions.

Testing Serverless Functions
Serverless computing, or functions-as-a-service, has picked up a lot of attention and speed due to its cost-effective pay-as-you-go price offering, multi-language/runtime support, as well as its easy learning curve without any need to provide the infrastructure layer. All the major cloud providers now have a serverless computing offer as part of their services portfolio: Amazon Web Services has Lambda, Microsoft Azure has Azure Functions, and Google Cloud has Cloud Functions. Furthermore, there are on-prem/on-Kubernetes options for running serverless functions on OpenWhisk or OpenFaaS. For the sake of consistency, I will refer to all of these services as serverless functions throughout the rest of this post.
In a microservices (or even nanoservices, as serverless functions are sometimes known) architecture, there are inherently lots of components, modules, and services that form part of an application or platform. This can make testing a chore, and sometimes a neglected part of the SDLC for these platforms. This article will explore some options and techniques for testing these types of platforms to help make this aspect of your projects easier. Testing should always be a first-class citizen, regardless of the infrastructure. Irrespective of the language, framework, or tools we use, testing is vital to ensure both sustained development velocity and the quality of our deliveries to production.

How To Boost Staff Retention and Empower Employees Using NodeJS, React, and Redis
Employees are the lifeblood of every business, making it absolutely crucial to align the right personnel with the right job. Doing so will transform a business into a well-oiled machine where every cog performs with maximum efficiency. Those who don’t will experience the rust that comes from a job mismatch, which usually translates to less productivity, high staff turnover rates, and blighted profits.
Having a poor employee retention rate is expensive, but trying to find the right candidate is a time-consuming process. What’s quite often the case is that businesses already have these skills available to them in their workforce, and only require a system that can transfer employees to positions that correspond with their talents.
