How To Improve GraphQL API Security

Aggregated on: 2023-06-29 15:31:01

The open-source GraphQL query language has a ton to offer enterprises seeking a more scalable, flexible, developer-friendly, and modernized approach to API-driven development. That said, because I’m a security professional, I tend to focus on the new opportunities GraphQL also gives attackers. It’s been increasingly tempting for enterprises to dive headlong into GraphQL without fully assessing and addressing its security and operational requirements. However, doing so places intense pressure on security architects, DevOps and DevSecOps teams, and even developers themselves. I’ve recently taken a deep dive into Inigo, a GraphQL security and management toolset. Here I’ll share a how-to guide for teams ready to introduce more secure GraphQL implementations based on what I’ve learned.

Own ChatGPT Bot in Telegram

Aggregated on: 2023-06-29 15:01:02

Recently, mirror sites providing access to ChatGPT have started to appear. However, using them is unsafe because such sites can collect and analyze all your correspondence. Especially those sites that provide such access completely free of charge. There is a demand for such sites because some countries block access to ChatGPT, and OpenAI blocks access to some countries. And for some users, 20 dollars for a ChatGPT subscription is expensive. So today, we will write our own chatbot based on ChatGPT in the Telegram messenger.

The Evolution and Coexistence of Web 2.0 and Web 3.0

Aggregated on: 2023-06-29 14:46:01

Web 3.0 has grown in popularity over the last few years and has fast become a tool for the empowerment of users in regard to ownership and sharing of data. The premise is that Web 3.0 will bring back the digital industry to a decentralized model, driving forwards, monetization, ownership, and governance, that was not as prominent through Web 2.0’s centralized model. The basic principles of technological evolution dictate that when a new model is created, it replaces the previous version; that’s precisely what happened between Web 1.0 and Web 2.0. However, Web 3.0 will not follow the same pattern; instead, it has the potential to enhance instead of replace Web 2.0.

Sticky Sessions With Apache APISIX

Aggregated on: 2023-06-29 14:46:01

Sticky sessions, also known as session affinity, is a mechanism by which a routing component that acts as a facade always routes a request to the same underlying upstream node. In this post, I'll describe the reason behind sticky sessions, available alternatives, and how to implement them via Apache APISIX. Why Sticky Sessions? Sticky sessions became popular when we stored the state on the upstream node, not the database. I'll use the example of a simplified e-commerce shop to explain further.

Best Practices for Writing Unit Tests: A Comprehensive Guide

Aggregated on: 2023-06-29 14:01:01

Why Unit Tests Matter Unit tests play a critical role in the software development life cycle. They allow developers to verify the correctness of individual code units, such as functions, methods, or classes. Here are some reasons why unit tests are crucial: Bug Detection: Unit tests help identify bugs and issues early in the development process, minimizing the chances of them propagating to other parts of the codebase. Code Refactoring: Unit tests provide a safety net when changing existing code. They ensure that the modified code continues functioning as expected, even after refactoring. Documentation: Unit tests serve as living documentation, showcasing how individual code units are intended to be used. They can help other developers understand the expected behavior and usage of specific code components. Regression Prevention: Unit tests act as a safety net against regressions. By re-running tests after making changes, you can quickly identify if any existing functionality has been inadvertently broken. Writing Effective Unit Tests Test Isolation To write reliable unit tests, it's essential to ensure test isolation. Each test should focus on a specific code unit and not depend on other units or external resources. By isolating tests, you better control the test environment and minimize the potential for false positives or negatives.

TDD and the Impact on Security

Aggregated on: 2023-06-29 12:31:01

Test-driven development (TDD) is a software development approach that prioritizes writing automated tests while creating the actual code. There follows a cycle of writing a failed test, writing the code to make the test pass, and then refactoring the code. TDD was originally developed to ensure the quality, maintainability and expandability of the software created over the long term. The specific knowledge about the individual source text passages should also be shown in the tests. Thus, a transfer of responsibility between developers is supported. Better than any documentation, tests are always up-to-date regarding the function implemented in the source code. However, TDD also has a positive impact on the security of a program. And that's what we're going to look at now.

Introduction To Non-Linear Data Structure

Aggregated on: 2023-06-29 12:01:01

Introduction To Non-Linear Data Structure Data structures are the backbone of computer programming. They provide a way of organizing and storing data in a computer’s memory, which allows efficient and fast access to that data. While many data structures are linear, meaning that they store data in a straight line or sequence, there are also non-linear data structures that store data in more complex ways. Data structures are essential tools for organizing and managing data in computer science. They are used to store, retrieve, and manipulate data efficiently. Non-linear data structures are one such category of data structures that allow for complex relationships and dependencies between data elements.

In this tutorial, we will use chat completion API to generate responses to a prompt (basically we can ask anything). Before starting with the tutorial, you can explore the API to have an understanding of how to authenticate to the API using API keys, how API request parameters and response look like.

A Deployment Is Not a Release: Control Your Launches With Feature Flags

Aggregated on: 2023-06-28 23:31:01

In the world of software development, the excitement of shipping code to users is often tempered by the inherent risks that come with each release. To mitigate these risks, one approach to choose is to decouple the deployment of code from when the feature goes live. This is achieved through a technique known as feature flagging. Feature flagging is a powerful tool that allows developers to safely push out new features to customers in a measured and gradual way. These features can be hidden behind if/then expressions in the code and can be made specific to some users or all of them. In this blog, you’ll learn about what feature flags are and how to use them, and discover the benefits they offer.

Seven Basic Principles of Good Software Engineering

Aggregated on: 2023-06-28 15:16:01

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.

Database Sharding and Its Challenges

Aggregated on: 2023-06-28 12:46:01

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.

Building Observable Applications With OpenTelemetry

Aggregated on: 2023-06-27 17:01:00

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: 2023-06-27 16:16:00

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: 2023-06-27 16:16:00

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: 2023-06-27 16:01:01

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: 2023-06-27 16:01:01

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.

Continuous Architecture Principles and Goals

Aggregated on: 2023-06-27 15:01:00

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.

Six Ways That Programming Helps To Develop Abstract Thinking

Aggregated on: 2023-06-27 14:16:00

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.

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.

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.
