Microservices With Apache Camel and Quarkus (Part 4)

Aggregated on: Thu Jun 15 2023 18:00:53 GMT+0000 (Coordinated Universal Time)

As we've seen previously, running our microservices in JVM mode means packaging and running them as executable JARs. But Quarkus also allows us to compile them into machine code and run them as native processes. This has the advantage of dramatically improving the application start-up time and memory usage. Hence, the native mode is the preferred execution mode of the Quarkus applications in production. All the whys and wherefores of the native mode are explained in a very clear and detailed manner in the Quarkus documentation. To resume, in order to compile Java code into machine one, a so-called "C native compilation environment" is required, as well as a GraalVM distribution. However, given the relative complexity of the GraalVM installation and configuration process, Quarkus is able to avoid it to us and offers the possibility to create Linux executable code without having to install and configure GraalVM. This is the modus operandi that we'll be adopting here.

Low Overhead Continuous Contextual Production Profiling

Aggregated on: Thu Jun 15 2023 16:30:53 GMT+0000 (Coordinated Universal Time)

In the realm of production applications, it is customary to address performance bottlenecks such as CPU and memory issues in order to identify and resolve their underlying causes. In order to gain insight into these problems, we gather a range of metrics and logs to monitor the utilization of system resources such as CPU, memory, and application-specific latencies. It is worth noting that this data collection process does not impact the performance of the application. However, it does not provide visibility into the operations taking place at the code level, such as method, socket, and thread states. Moreover, the process of collecting these profiles introduces overhead during application runtime and necessitates the storage and visualization of significantly large datasets. This article explores the concept of low overhead high-frequency profilers, which offer a solution to these challenges. It delves into methods for attaching application context to profile samples, enabling the collection of profiles from tens of thousands of application deployments. Additionally, it discusses efficient strategies for storing and visualizing stacks, introduces a novel approach to comparative analysis, and explores aggregation techniques for an extended duration.

Waterfall Software Development

Aggregated on: Thu Jun 15 2023 15:30:53 GMT+0000 (Coordinated Universal Time)

What Is Waterfall Software Development? Waterfall software development is a traditional project management approach that follows a linear and sequential process. It is characterized by distinct phases, with each phase being completed before the next one begins. The approach gets its name from the cascading flow of activities from one phase to another, much like a waterfall. Some Typical Phases of the Waterfall Software Development Model Requirements Gathering: In this phase, the project requirements are gathered and documented. This involves understanding the client's needs, identifying project goals, and creating a comprehensive requirements document. Framework Plan: When the necessities are laid out, the framework configuration stage starts. This involves creating a detailed system architecture and design based on the gathered requirements. The design includes software modules, data structures, user interfaces, and any other relevant components. Implementation: In the implementation phase, the development team starts coding and programming based on the system design. Each module is developed and integrated into a complete software system. Testing: After the software is implemented, it undergoes testing to identify and fix any defects or issues. Testing incorporates unit testing, mix testing, framework testing, and client acknowledgment testing. This phase aims to ensure that the software functions as intended and meets the specified requirements. Deployment: Once the software has passed testing and received approval, it is deployed to the production environment or delivered to the client. This phase involves installation, configuration, and making the software available for end-users. Maintenance: After organization, the product enters the upkeep stage. This involves ongoing support, bug fixes, updates, and enhancements based on user feedback and changing requirements. The waterfall model emphasizes a structured and sequential approach, where each phase has well-defined inputs and outputs. It is suitable for projects with stable and clearly defined requirements, where changes are less likely to occur. However, it has limitations in accommodating changes during development, as the next phase cannot begin until the previous one is completed.

So, you’re a day one Scrum Master, and you’ve landed your first job! Congratulations, that’s really exciting! This is an exciting time, but it can also be a bit daunting. There are a lot of things to learn in your first month on the job. In this blog post, we will provide you with a guide to help you hit the ground running. We will discuss essential tips for setting up your environment, getting started with sprints, and building relationships with your team. Let's get started! Starting a new job as a Scrum Master can be overwhelming. There's so much to learn and absorb before you can start making changes. The key to establishing yourself as a trusted member of the team is to listen and learn during your first sprint. It's important to get to know your team members and what motivates them, to understand how they work together and where there may be challenges. By taking the time to soak up all this information, you'll be better positioned to suggest changes that will be both productive and well-received. Remember, the first few weeks are about learning, not changing.

A/B Testing Was a Handful Until We Found the Replacement for Druid

Unlike normal reporting, A/B testing collects data from a different combination of dimensions every time. It is also a complicated kind of analysis of immense data. In our case, we have a real-time data volume of millions of OPS (Operations Per Second), with each operation involving around 20 data tags and over a dozen dimensions. For effective A/B testing, as data engineers, we must ensure quick computation as well as high data integrity (which means no duplication and no data loss). I'm sure I'm not the only one to say this: it is hard!

govGPT: Improving Citizen Experience with Chatbots

Aggregated on: Wed Jun 14 2023 14:15:51 GMT+0000 (Coordinated Universal Time)

I see the new class of large language model (LLM) based conversational AI tools as third-generation chatbots. The likes of ChatGPT, Bard, and their OSS alternatives are boosting automation and transforming businesses — from internal operations to banking and healthcare. Furthermore, fine-tuned LLM-based chatbots can be used to significantly improve the efficiency, accuracy, and transparency of governmental operations. This article will discuss some of the issues with current citizen experiences related to governance and how chatbots can address the shortcomings. Anyone who dealt with a DMV to schedule and get a driver’s license would know how frustrating the entire endeavor can be. While scheduling a DMV has become a nightmare post-COVID, what’s even more frustrating is the difficulty in gathering accurate information about the required documentation. For legal immigrants, the difficulty is further exacerbated. Part of the problem is that DMV websites are typically hard to search and navigate. And the information that one finds tends to be pretty vague and generic. A good solution to this problem would be to provide a public-facing chatbot that is built and fine-tuned on relevant Code of Federal Regulations (CFRs), state and local government regulations, and other government databases. Such a chatbot would enable the citizen/resident to converse in natural language, specify their unique situation and get accurate guidance to easily apply for a driver’s license. In fact, the chatbot could even schedule an appointment on the user’s behalf at their local DMV.

Queue in Data Structures and Algorithms

Queue, for example, is a sequence of people who are standing for buying a metro ticket or ordering food at a store. The first person entering the queue leaves first. Similarly, the last person entering the queue leaves at the last. These queues help in managing the flow of customers and lower the chances of rush while buying. In this blog, we further discuss queue implementation, how it is related to data structures, and its real-time applications.

Javascript Variables (Beginner Thinking)

Programming is all about manipulating and displaying data, which can be any kind of information used in computer programs, such as social media usernames, age, and profile photos. To work with this data and create interesting things, programmers need a way to store and keep track of it. This is where the concept of variables comes in. A variable is an essential concept in almost every programming language, and there is much to know and understand about it. It is important for us to have a clear and deep understanding of these concepts related to the Variable.

How We Made Our ChatGPT Chatbot 10X Faster

Aggregated on: Wed Jun 14 2023 13:45:51 GMT+0000 (Coordinated Universal Time)

A ChatGPT-based website chatbot can dramatically reduce your website's performance. A decent chatbot needs to download reCAPTCHA. This is a heavy library, blocking rendering during downloads, significantly impacting the performance of your website. A slow website scores badly on SEO, something we published an article about last week. You should, therefore, carefully measure the performance of your website both before and after including a chatbot on your website, or you might be up for a surprise as you see organic clicks from Google drop like a stone in water because you wanted "a cool ChatGPT-based website chatbot on your site." We just made some huge performance gains on our own chatbot technology. The way we did it was by deferring the loading of reCAPTCHA libraries until the chatbot is activated. Let's face it, your chatbot is amazing, but most people come to your site to see (duh!) your site and not your chatbot. Hence, loading reCAPTCHA before it's needed is a waste. reCAPTCHA is also an extremely poorly written JavaScript library, blocking DOM rendering for 3 to 4 seconds on phones. Yes, I know, the irony...

Revamped ShardingSphere-On-Cloud: What’s New in Version 0.2.0 with CRD ComputeNode

Aggregated on: Wed Jun 14 2023 13:15:51 GMT+0000 (Coordinated Universal Time)

The latest version of Apache ShardingSphere-On-Cloud, version 0.2.0, has introduced a new CRD ComputeNode for ShardingSphere Operator. This brand-new addition provides users with the ability to define computing nodes entirely within the ShardingSphere structure. Introduction to ComputeNode The primary building blocks of Apache ShardingSphere's traditional architecture are computing nodes, storage nodes, and governance nodes. The ShardingSphere Proxy acts as the computing node and serves as the entry point for all data traffic. It's also in charge of data governance functionalities like distribution and balancing. The storage node is where all ShardingSphere metadata is stored, including sharding rules, encryption rules, and read-write splitting rules. Governance node components like Zookeeper and Etcd make up the governance node.

Storage Array

In today's digital age, data is king, and businesses and individuals alike rely on the storage and retrieval of data to keep their operations running smoothly. Storage arrays are a type of storage solution that has become increasingly popular for their ability to store large amounts of data reliably and efficiently. In this article, we will discuss what a storage array is, its benefits, and its use cases. What Is a Storage Array? A storage array is a type of storage system that comprises multiple storage devices, such as hard disk drives (HDDs) or solid-state drives (SSDs), that are grouped together into a single system. This allows for the creation of a large storage pool that can be managed centrally, making it easier to store, access, and manage large amounts of data. A storage array can be thought of as a centralized data repository that can be accessed by multiple users and applications simultaneously.
