Seven Basic Principles of Good Software Engineering

Aggregated on: Wed Jun 28 2023 15:16:01 GMT+0000 (Coordinated Universal Time)

DRY (Don't Repeat Yourself) The DRY (Don't Repeat Yourself) principle is a fundamental concept in software engineering that promotes code reuse. It states that if you have written a piece of code, then it should be reused throughout the codebase rather than repeated somewhere else. It advocates for avoiding duplication of code or logic and encourages developers to strive for a single source of truth. By adhering to DRY, you'll get the following benefits: Improved Code Quality: Duplicated code is prone to inconsistencies. By adhering to the DRY principle, developers ensure that code is written once and reused whenever needed, which greatly improves the quality of the system. Time and Effort Savings: Duplicated code requires redundant efforts. When changes or updates need to be made, developers have to modify the code in multiple places, which consumes time and also increases the risk of introducing errors. The DRY principle helps save valuable time and effort by centralizing code logic. Read more about the DRY principle here.

Aggregated on: Wed Jun 28 2023 13:46:01 GMT+0000 (Coordinated Universal Time)

Scalability testing is an approach to non-functional software testing that checks how well applications and infrastructure perform under increased or decreased workload conditions. The organization can optimize infrastructure costs and create the best user experience by determining server-side robustness and client-side degradation. It makes it easier to fix defects and ensure software applications' flawless functioning. As part of the testing process, testers usually draft test scenarios that force the system to meet new requirements.

Database Sharding and Its Challenges

Aggregated on: Wed Jun 28 2023 12:46:01 GMT+0000 (Coordinated Universal Time)

Database sharding is a powerful technique employed to manage large databases more effectively. It involves partitioning a large database into smaller, more manageable parts, known as shards. The term "shard" signifies a small fragment of a whole, aptly describing this method of breaking down a large database into smaller, more manageable pieces. Sharding is often applied to databases for several reasons, including improving query performance, facilitating data organization, and enhancing scalability. By distributing data across multiple servers, sharding can significantly reduce the response time for data queries, provide a more organized data structure, and allow for easier scaling as the amount of data grows. The above diagram presents a visual representation of a sharded database. The primary database is segmented into smaller shards, each of which is stored on a distinct server.

Introduction to Semaphores

Semaphores are an important tool for managing concurrency in computer programs. They are used to manage access to shared resources in a multi-threaded environment and help prevent synchronization issues and coordinate access to shared resources. The concept of semaphores was first introduced by Edsger Dijkstra in 1965, and they have since become a fundamental tool for developing efficient and effective software. This article will explore semaphores, how they work, and some best practices for using them in your programs.

Building Observable Applications With OpenTelemetry

Aggregated on: Tue Jun 27 2023 17:01:00 GMT+0000 (Coordinated Universal Time)

In the ever-evolving landscape of software development, complexity is a constant companion. As applications grow and evolve, they become increasingly intricate, making it more challenging to monitor, understand, and optimize their behavior. Developers are increasingly responsible for adding instrumentation into their code so the inner workings of their applications can be observed externally. That data then provides valuable insights to stakeholders across the business. This is where the concept of observability comes into play. Observability, in the context of software, refers to the ability to understand the internal state of a system by examining its outputs. It's like being able to understand what's happening inside a machine by just looking at the dials and gauges on its control panel.

What Is Model Ops?

Aggregated on: Tue Jun 27 2023 16:16:00 GMT+0000 (Coordinated Universal Time)

The rapid implementation of various new applications, cloud services, and other technologies has complicated IT environments too much for humans to handle, negatively affecting profits. It is difficult for companies to pursue digital transformation in a highly competitive market despite the significant investments they've put into artificial intelligence. They cannot streamline all organizational models, making it difficult to gain valuable insights from the models and make informed business decisions. Scaling all available models from the dev region to the CI/CD pipeline to the deployment region can be a challenging process for DevOps teams within traditional siloed environments. The challenge gets even more difficult when you have to monitor and manage all these models in production for performance, drift, bias, and other risks. All this while adhering to international and local regulations until the model decays or is retired.

The Impact of Microservices: The Good, the Bad, and the Ugly

Aggregated on: Tue Jun 27 2023 16:16:00 GMT+0000 (Coordinated Universal Time)

Reliance on technology has come full circle since the start of the COVID-19 pandemic. The increased utilization of digital applications for needs such as banking, shopping, and especially healthcare services during the past three years has ushered in a need for consumers to trust technology to assist them in all aspects of daily living. Not coincidentally, the demands placed on app engineers, developers, and designers today require them to offer a level of versatility within their software that was not needed just a few years ago. At a time when the incidence of cybersecurity attacks is at an all-time high, it is now necessary for apps to be built and scalable in a more flexible manner so that they can be addressed appropriately in the event of an incident that requires intervention. Microservices architecture is a more suitable way to improve the reliability and scalability of today’s software systems. In a microservices cloud-based architecture, a large application is broken down into smaller, independent services that communicate with each other through application programming interfaces (APIs). This allows for more focused development and deployment and easier maintenance and scaling. A microservices approach is in stark contrast to monolithic software applications, which are built as single, unified units that are more complicated and time-consuming to build and deploy.

How to Convert Excel and CSV Documents to HTML in Java

Aggregated on: Tue Jun 27 2023 16:01:01 GMT+0000 (Coordinated Universal Time)

When it comes to organizing, structuring, and formatting data for everyday report presentations and report-sharing scenarios, Excel is decisively the world’s go-to spreadsheet solution. And that’s for good reason – Excel’s extensive and endlessly updated features are perfect for most of our manual data manipulation needs, allowing us to quickly generate stylish rows and columns with slick graphs and other forms of visuals. The open-XML .XLSX format also transitions nicely into plain text formats like CSV, making it equally straightforward to export and upload Excel’s tabular data to a broader range of compatible applications. Despite its myriad features and format conversion fluidity; however, document compatibility concerns are always lurking when we look to share Excel report content with the broadest possible audiences. Of course, we don’t have to look very far to find a global, standardized solution to this long-standing challenge. Where fully formatted and finished data reports are concerned, PDF represents the ideal export format, owing largely to its universal compatibility and secure design. Excel and CSV documents converted to PDF format are viewable on any browser, and these PDFs can be formed as vector or raster files depending on the document creator’s personal preference.

PyCharm Fix for Certificate Verify Failed: Unable To Get Local Issuer Certificate

Aggregated on: Tue Jun 27 2023 16:01:01 GMT+0000 (Coordinated Universal Time)

When your organization installs a security monitoring app like Zscaler on your workstation, it could hinder your productivity by blocking many existing third-party apps you have been using for your development or testing deliverables. In many cases, once installed, you will have no problem accessing public URLs via browser but will still face challenges when trying to access via terminal or IDE. Although when organizations install security apps, they add company-generated certificates in the system cert, some applications like Java, Python, IDE, NPM, etc. do not use default system cert and have their own custom trust store, which fails to validate Zscaler-generated server certificates, and the TLS connection fails.

Managing Schema Validation in a Data Lake Using Data Version Control

Aggregated on: Tue Jun 27 2023 15:46:00 GMT+0000 (Coordinated Universal Time)

It’s not uncommon for a data team to be dependent on many other “third parties” that send in the data. They often change the schema of the data without communicating anything or letting the data team know too late. Whenever that happens, data pipelines break, and the data team needs to fix the data lake. This is a manual process filled with heavy-lifting tasks. Typically, teams engage in a blame game, trying to prove that the schema has changed.

In today's (mostly) digital world, maintaining data privacy and data security should be an ongoing discussion in all businesses, especially those developing applications, both internal business shops and software shops selling solutions. That said, compliance and privacy issues are not restricted to just digitally-stored data and may, in fact, be a larger issue for older, analog records that aren't as front-and-center as I realized this past weekend.

Continuous Architecture Principles and Goals

Aggregated on: Tue Jun 27 2023 15:01:00 GMT+0000 (Coordinated Universal Time)

Creating and maintaining software architecture that remains sustainable over time is a challenge for software architects and developers. Software Architects used to meet every requirement, provide every feature, and plan every system component at once with big software architecture upfront, which involves completing and perfecting architectural designs before implementations are started. Alternatively, teams might produce emergent architectures, where development teams start delivering functionality and let architectural designs emerge with little upfront planning. Unfortunately, none of those methods is consistently successful in delivering sustainable architecture. Continuous Architecture Principles As for “Continuous Architecture,” this is about using the appropriate tools to make the right decisions and support Continuous Delivery, Continuous Integration, and Continuous Testing. “Continuous Architecture” is an approach based on a toolbox — not a formal process.

Have you ever tried to imagine a concept or idea without a physical or concrete example? If you have, then you've engaged in abstract thinking. Abstract thinking is the ability to understand complex concepts that are real but not physically tangible. It is a key cognitive function that allows us to comprehend things like values, emotions, or the very idea of 'infinity.' In our daily lives, abstract thinking plays a significant role. It enables us to plan for the future, understand other people's perspectives, solve problems, and even appreciate art or literature. It's an essential skill for many professional fields, including science, mathematics, philosophy, and, yes, you guessed it — programming.

Building an Event-Driven Architecture Using Kafka

Aggregated on: Tue Jun 27 2023 14:16:00 GMT+0000 (Coordinated Universal Time)

Event-driven architecture (EDA) is a software design pattern that focuses on the generation, detection, and consumption of events to enable efficient and scalable systems. In EDA, events are the central means of communication between components, allowing them to interact and respond to changes in real time. This architecture promotes loose coupling, extensibility, and responsiveness, making it well-suited for modern, distributed, and highly scalable applications. EDA has emerged as a powerful solution to enable agility and seamless integration in modern systems. In an event-driven architecture, events represent significant occurrences or changes within a system. Various sources, such as user actions, system processes, or external services, can generate these events. Components, known as event producers, publish events to a central event bus or broker, which acts as a mediator for event distribution. Other components, called event consumers, subscribe to specific events of interest and react accordingly.

Using Query Parameters and Headers in REST API Design

In today's fast-paced digital landscape, REST APIs are essential for connecting and exchanging data between different systems and applications. But with so many different components and considerations, it can be a challenge to design an API that is both efficient and user-friendly. One key aspect of REST API design is the use of query parameters and headers. Query parameters allow you to pass information to the API in a simple and flexible manner, while headers provide important information about the request and the response. When used together, query parameters and headers can greatly enhance the performance, security, and user experience of your REST API.

Exploring Unit Testing in Golang

Aggregated on: Tue Jun 27 2023 14:01:00 GMT+0000 (Coordinated Universal Time)

Unit testing is a fundamental practice in software development that focuses on testing individual units of code, typically at the function or method level. A unit is the smallest testable part of an application, such as a function, method, or class. The objective of unit testing is to verify that each unit of code works as expected in isolation. Here Are Some Key Aspects of Unit Testing Isolation Unit tests are designed to be independent and isolated from other units of code. This means that each unit(a.k.a functions, methods) is tested in isolation, without dependencies on other units or external resources. This is usually achieved by using test doubles, such as mock objects or stubs, to simulate the behavior of dependencies.

Techniques for Optimizing Costs on AWS DynamoDB Tables

Aggregated on: Mon Jun 26 2023 22:46:00 GMT+0000 (Coordinated Universal Time)

AWS DynamoDB, a fully managed NoSQL database service, provides high performance and scalability for applications. While DynamoDB offers incredible capabilities, it is important to implement cost-saving strategies to optimize the usage of DynamoDB tables. In this article, we will explore some techniques and technical approaches to save costs on AWS DynamoDB tables while maintaining performance and scalability. Right-Sizing Provisioned Capacity To optimize costs, accurately estimate the required provisioned capacity for your DynamoDB tables. Provisioned capacity requires specifying a fixed number of read and write units. Monitor your application's traffic patterns using Amazon CloudWatch metrics and DynamoDB's built-in dashboard. Analyze the data and adjust the provisioned capacity based on the observed usage patterns. By avoiding overprovisioning and underutilization, you can significantly reduce costs associated with provisioned throughput.

Evaluating Apache APISIX vs. Spring Cloud Gateway

Aggregated on: Mon Jun 26 2023 22:01:00 GMT+0000 (Coordinated Universal Time)

Given the number of API Gateways available on the market, I'm regularly asked which is better. Better is a very subjective term. However, there's no denying that if you're advocating for a product, you should know your product and its competitors. In this post, I'd like to share my understanding of Spring Cloud Gateway and how it compares to Apache APISIX. I'm cautious when comparing products because most comparisons I read are heavily biased. That's a risk, especially when working on one of the products one is comparing. I'll also avoid "benchmarketing" - when you benchmark products in a context that favors your own; I'll focus on the so-called Developer Experience.

Adhering to Privacy Laws When Preserving System History

Aggregated on: Mon Jun 26 2023 19:01:00 GMT+0000 (Coordinated Universal Time)

Privacy laws worldwide prohibit access to sensitive data in the clear such as passport numbers and email addresses. It is no different when persisting to operational logs. One approach can be to anonymize the data before persisting it. However, this only allows for technical and business investigations. Another approach is to rely on the operating system to prevent unauthorized access using security groups or some such mechanism. This might be the easiest way to gain compliance. However, this approach relies heavily on human effort, and humans make mistakes. Furthermore, system administrators with root access will be able to view sensitive data in the clear. Another approach that comes to mind is to share a symmetric key between the system doing the logging and all entities vetted for read access. In such a scheme, the application will encrypt selectively before writing to the log, allowing for users to decrypt when required. This approach begs the normal questions of how to share the key securely for the first time or during the key rotations mandated by the organization’s security policies. Not to mention the security risk of so many entities having access to the key.

The Importance of API Versioning and Best Practices for Microservices

Aggregated on: Mon Jun 26 2023 18:46:00 GMT+0000 (Coordinated Universal Time)

Microservices architecture has emerged as a popular solution for building complex and scalable applications. In a microservices architecture, an application is broken down into a collection of loosely coupled, independently deployable services that communicate with each other via APIs. This approach offers many benefits, including improved scalability, reliability, and flexibility. However, managing the APIs in a microservices architecture can be challenging, especially as the number of services grows. This is where API versioning comes in. API versioning is the practice of creating multiple versions of an API to support different clients and use cases. It helps ensure that changes to an API don't break existing clients and provides a way to evolve the API over time.

Reshaping the Cloud To Meet Modern Workloads

Aggregated on: Mon Jun 26 2023 18:16:00 GMT+0000 (Coordinated Universal Time)

The Amazon Prime Video team recently published a blog post that made waves among the cloud and developer communities. In the post, the team detailed how moving one of their monitoring tools from a distributed serverless architecture to a monolith helped lower costs and increase scalability. So, is this the end or serverless, as some are calling it? Hardly. Just because the Prime Video team realized that a monolith architecture worked best in this use case does not mean that it should be the go-to architecture for monitoring tools. Those decisions should be made by individual teams choosing the best technologies and architecture for their own cloud deployments. Serverless makes a lot of sense for a multitude of use cases, especially streaming video.

The Saga pattern is often positioned as a better way to handle distributed transactions. I see no point in discussing Saga's advantages and disadvantages because Saga should not be used at all in the microservices-based systems: If you need distributed transactions across a few microservices, most likely you incorrectly defined and separated domains.

Agile Git Branching Strategies in 2023

Aggregated on: Mon Jun 26 2023 17:46:00 GMT+0000 (Coordinated Universal Time)

I have experience working on many projects, and I have found that the right choice for a branching strategy is essential for project success. In this article, I’ll describe different branching strategies. Nowadays, Git-Flow is very popular and well-documented. However, there are a few other alternatives like GitHub-Flow and the Trunk-based approach that exist, and some teams tend to move away from git-flow, and this article will describe why some other branching models may work better for your and your team. Why Do We Need Git? The reason why we have to use a (distributed) version control system like Git, and another, seems very obvious since it is used in almost every project, and having (D)VCS seems a standard nowadays. However, the question is why it is so. The answer is we are using version control because, as a team, we want to collaborate our effort to work on the same product and the same goal, and with the use of (distributed) version control systems like Git, we can integrate our individual contributions into a single product.
