Why ORMs and Prepared Statements Can't (Always) Win

Aggregated on: Fri Jun 30 2023 15:16:02 GMT+0000 (Coordinated Universal Time)

Developers were told to use ORMs and prepared statements to avoid SQL injections for a long time now. By doing so, they effectively separate instructions (the semantics of the SQL query) from the data. Modern languages and frameworks often also abstract away the need to write raw queries, offering high-level interfaces around our database models. Unfortunately, that's not enough to thwart away SQL injections once and for all, as these APIs can still present subtle bugs or nuances in their design. In this blog post, I show you how the misuse of a Golang ORM API introduced several SQL injections in Soko, a service deployed on the Gentoo Linux infrastructure. Then, I look further into assessing the impact of this vulnerability by using a PostgreSQL feature to execute arbitrary commands on the server.

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.

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: Thu Jun 29 2023 12:01:01 GMT+0000 (Coordinated Universal Time)

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 article, we will explore how to integrate OpenAI's ChatGPT APIs with a Spring Boot application and manage the APIs using Apache APISIX, an open-source API gateway. This integration will allow us to leverage the power of ChatGPT in our Spring Boot application, while APISIX will provide a robust, scalable, and secure way to manage the APIs. OpenAI ChatGPT APIs OpenAI's ChatGPT API is a powerful tool that we can use to integrate the capabilities of the ChatGPT model into our own applications, or services. The API allows us to send a series of messages and receive an AI model-generated message in response via REST. It offers a bunch of APIs to create text responses in a chatbot, code completion, generate images, or answer questions in a conversational interface. 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: Wed Jun 28 2023 23:31:01 GMT+0000 (Coordinated Universal Time)

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.
