Full-Duplex Scalable Client-Server Communication with WebSockets and Spring Boot (Part II)

Aggregated on: Fri Jun 12 2020 17:30:03 GMT+0000 (Coordinated Universal Time)

Secure WebSockets Over SSL/TLS To prevent man-in-the-middle attacks between server and client, it is strongly recommended to use the WSS protocol, to send encrypted TCP messages. This is the equivalent of using HTTPS instead of HTTP. Setting Up NGINX We will use NGNIX as a reverse proxy that forwards all incoming requests to the Spring Gateway MS. We will configure the proxy to listen to port 443 which is the default port for secure connections in both HTTPS/WSS.

A handy resource for generating a long-lived refreshToken is the OAuth playground.

Selecting the Right Agile Framework - Coveros

Aggregated on: Fri Jun 12 2020 17:30:03 GMT+0000 (Coordinated Universal Time)

Scrum. Kanban. Lean. XP. SAFe. RUP. Scrum of Scrums. There are many frameworks available to organizations that are maturing their agile software development process. However, the use of some frameworks can help reinforce agile behaviors, while others can be degenerative and actually drive an organization to revert to more waterfall-like software development.The choice of agile framework should be a collaborative discussion between teams, organizational leadership, and any stakeholders. Every part of the team should have input into what key features they will need from the framework. The "correct choice" will depend on many variables, including the nature of the work, the experiences of the organization, cultural factors, and changes desired to meet the work objectives.

Why You Need Agile Business Intelligence and Data Analytics

Aggregated on: Fri Jun 12 2020 15:10:02 GMT+0000 (Coordinated Universal Time)

Many business users are raising complaints about reporting and analytics that took a lot of time to develop with the IT team. One research found that traditional BI is unable to provide quick reporting and solutions to industries in this competitive world. Companies are spending a lot of time and money on modeling data when it appears that models have evolved the approach changes. So, it is juggling to do it again and the problem is too large to find a solution. Seeing the difficulty of distributing BI applications to managers and executives that they are unable to make the right decisions; it has become imperative that an alternative development approach is needed. In fact, there is a widespread and growing consensus that the time for Agile BI has arrived.

Since its release in 2015, GraphQL has become the alternative to REST. It gives frontend developers the flexibility they had craved for for so long. Over are the days of begging backend developers for one-purpose-endpoints. Now a query can define all the data that is needed and request it in one go, cutting latency down considerably.

Creating EFS Using CloudFormation and Mounting it With EC2 Linux Instance

Aggregated on: Thu Jun 11 2020 23:10:03 GMT+0000 (Coordinated Universal Time)

There are multiple ways of storing information on an instance, like EBS or EFS. EBS is Elastic Block Storage and can be considered as if you have a high capacity Storage Device attached to your computer. Whereas EFS is Elastic File Storage and can be considered as if you have attached an external storage device attached to your computer. It may depend on your application or use case you choose to use what among both, but for our case, that we are discussing today, we are going to use EFS with EC2 Linux instance. Create EFS Using CloudFormation Let's create EFS using CloudFormation. You can use the following template to create the resource.

How to Reduce Software Maintenance Cost of Existing Technology Products

Aggregated on: Thu Jun 11 2020 20:00:03 GMT+0000 (Coordinated Universal Time)

The cost of maintaining software is rising exponentially and it has been found that software maintenance could account for 70% of the total cost of the software. There are reasons behind this. While more and more software is being developed every day, it becomes hard to maintain them over time. Lack of proper reporting or documentation and people who work on its development retire or leave without being replaced. Re-engineering the system is not an option because the system that needs to be rebuild could be extensive and not well documented.

TiDB Dashboard: Easier Troubleshooting for Distributed Databases

Aggregated on: Thu Jun 11 2020 20:00:03 GMT+0000 (Coordinated Universal Time)

It's challenging to troubleshoot issues in a distributed database because the information about the system is scattered in different machines. TiDB is an open-source, distributed SQL database that supports Hybrid Transactional/Analytical Processing (HTAP) workloads. Before version 4.0, it could be difficult to efficiently troubleshoot TiDB's system problems. To diagnose a TiDB cluster's issues, even an experienced database administrator (DBA) needed to understand TiDB's basic architecture, get familiar with thousands of TiDB monitoring metrics, and gain experience in the field to ensure that when they encountered similar problems next time, they could fix them more quickly.

Working With Timers in Node.js

Aggregated on: Thu Jun 11 2020 18:50:03 GMT+0000 (Coordinated Universal Time)

Timers are polyglot. They are very useful in many use cases. Almost all major programming languages supports them, and Node.js is no exception. It's actually more simple in Node because Node lets us reuse our existing learning of timers. In this post, I will describe and demonstrate what timers are, how to use them, what the syntax looks like, and then how you can leverage them in your applications. One common example, if you want to retrieve data from a REST API on specific interval, you can achieve very easily using timers. So, even if you are new to JavaScript or timers, this post will help you understand these concepts. If you are interested in knowing more about Node, you can also check my other articles as well.

Oracle's Raspberry Pi Supercomputer, the largest Raspberry Pi cluster known to exist, got awarded one of the Top 10 Raspberry Pi Projects of 2019 from Tom's Hardware. Here Is Its Story In 2018, a small group of enthusiastic presales people from Oracle Switzerland presented their 12-node Raspberry Pi cluster at the Hackzurich hackathon. The cluster was stacked up in a 3×4 node configuration, mimicking an Oracle Cloud data center with 3 availability domains. It ran a fully operational Kubernetes cluster on top of it and could demo node and availability domain failovers. The cluster turned out to be quite the people magnet. Flashy LEDs, a cute looking cluster, and the unsatisfiable curiosity of "what is it doing?" The foundation for the Raspberry Pi Supercomputer has been laid.

Automatically Filter Image Uploads According to Their NSFW Score

Aggregated on: Thu Jun 11 2020 17:40:03 GMT+0000 (Coordinated Universal Time)

When developing and later administrating a web or mobile application that deals with a lot of image uploads, shares, likes and so forth, you would want to set up a smart automated mechanism that moderate your users' image, GIF or video uploads on the fly and act accordingly when NSFW content is being detected such as rejecting, flagging or even censoring (i.e. apply a blur filter to) the target picture or video frame being suspected. Since images and user-generated content dominate the Internet today, filtering NSFW contents becomes an essential component of Web and mobile applications. NSFW is the acronym for not safe for work and refer to images or GIF frames that contain adult content, violence or gory details.

First Look at Apicurio Service Registry UI and Operator

Aggregated on: Thu Jun 11 2020 16:30:02 GMT+0000 (Coordinated Universal Time)

The Apicurio community launched last year the new Apicurio Registry project targeted as an API and schema registry for services. It allows you to store and retrieve service artifacts. For example, OpenAPI specification and AsyncAPI definitions as well as Avro, JSON, and Google protocol buffer schemas. This registry also works as a catalog, allowing you to navigate through the artifacts. Consequently, having an user interface was a vital feature that needed to be added. The latest 1.2.2 release added the new web-based user interface to the project. The release is now available as a binary download as well as container images. In fact, to make it easier to set up and manage the deployment of the solution on Kubernetes, there is now a new Kubernetes Operator available for the Apicurio Registry.

5 Agile Anti-Patterns That Distributed Teams Should Avoid

Aggregated on: Wed Jun 10 2020 21:00:03 GMT+0000 (Coordinated Universal Time)

As agile becomes a predominant part of the Software Development Life Cycle (SDLC), the methodology also brings to the fore the challenges of handling the agile anti-patterns at every level of the process. Anti-patterns are apparent and familiar fixes for common problems in an agile workflow, which turn out to be counter-productive to the process. They may appear to offer a solution to a problem at hand but have several underlying inconsistencies. How Teams Can Avoid Agile Anti-Patterns A potential solution turns into an anti-pattern when it does not offer a suitable fix, or it is repeated too many times for a negative impact. However, anti-patterns do differ from malpractices - they are not incorrect remedies to the existing problem, but rather cause issues when used too frequently. So how would you fight an enemy you can't see? Well here are 5 of the most common agile anti-patterns and tips to avoid them:

Create More Management Transparency

Aggregated on: Wed Jun 10 2020 19:50:03 GMT+0000 (Coordinated Universal Time)

In the agile and lean communities, we talk a lot about transparency. I see the most product and program success when the various teams create transparency between them, the middle of the continuum. That's the full-product transparency. I see many organizations succeed better when the less the manager knows, the better the team works. And, when there's too little manager-to-team transparency, the efforts become much more difficult or fail. That's because the managers don't explain: Why this product Why focus on these customers Why this product now, as opposed to any of the other work we could do. The managers don't explain the purpose. So, the managers request transparency about the teams' work. And, the managers don't offer transparency about the purpose. That's not reciprocal transparency.

Do You Really Want To Be A Manager?

Aggregated on: Wed Jun 10 2020 18:40:04 GMT+0000 (Coordinated Universal Time)

Every person at some point in their career may need to ask themselves "Do I really want to be a manager?" The question may seem straightforward, but the answer is not. It requires digging deeper and finding answers for ourselves without relying on what others believe is the right thing for us to do. Management may seem like a natural career progression for a great individual contributor, while it may not be the best way to expand our role. Much like our earlier decisions that landed us in a particular field, the choice to be a manager or not requires careful examination of our options. Management isn't the only way to grow, get a raise, or take on additional responsibilities from our current role. Think of management as a maze with a simple entry that requires navigating multiple unknown paths along the way. It's easy to get lost, feel stuck, and lose hope unless we have patience, curiosity, and the ability to learn from its unique challenges. It requires reprogramming our brain to accept responsibility not only for ourselves but also for the team and provide the necessary tools and resources to help them succeed.

Why Set Is Better Than List in @ManyToMany

Aggregated on: Wed Jun 10 2020 17:30:03 GMT+0000 (Coordinated Universal Time)

In this article, we'll highlight the performance penalties involves by using List or Set in @ManyToMany relationships. We use Spring Data JPA with the default persistence provider, therefore with Hibernate JPA. First of all, keep in mind that Hibernate deals with @ManyToMany relationships as two unidirectional @OneToMany associations. The owner-side and the child-side (the junction table) represents one unidirectional @OneToMany association. On the other hand, the non-owner-side and the child-side (the junction table) represent another unidirectional @OneToMany association. Each association relies on a foreign key stored in the junction table.

The jpackage Utility Revisited for JDK14 [Video]

Aggregated on: Wed Jun 10 2020 16:20:02 GMT+0000 (Coordinated Universal Time)

A previous post of mine introduced and demonstrated jpackage, a utility that enables the packaging up of Java applications in native installer format for Windows, MacOS or Linux. Kindly disregard that post, and instead use the associated video in this article as a current reference. At the time of the original article's creation, it was in early prototype form and only available in a special build of JDK13. With the arrival of JDK14, jpackage has been formally incorporated into the JDK as an incubator module called jdk.incubator.jpackage. The rationale for revisiting this topic lies in the fact that APIs have changed; in particular, the command-line arguments associated with the jpackage utility are different. The video that follows walks through the building of a sample modularized Java application, then proceeds to first create a jlink'ed runtime image of that application, before ultimately demonstrating how to use jpackage to create a Windows-native installer of that application. It then briefly shows how those same tasks can be performed on Linux and MacOS platforms too.

Shadow Root DOM and Custom HTML Tags Automation Using Selenium

In this article, we will try to solve a multi-level shadow DOM automation problem using an open-source GitHub project that will let you test multi-level shadow DOM elements in your Java Selenium project. We will use Chrome as the main browser for testing this feature since Chrome v53+ fully supports shadow DOM. Now let's talk about how this all started. I was working with a project that works on a workflow automation tool called Frevvo. In one of the improvements, we started using the Google Polymer framework that creates shadow DOM elements. As our automation framework was developed with Java Selenium, we were stuck, as the Selenium tool was not able to find elements under the shadow DOM.
