Exploring Python's New Subinterpreters

Exploring Python’s New Subinterpreters The Python community never ceases to innovate. One of the most recent additions to Python’s vast feature set is “subinterpreters”. As the name suggests, subinterpreters provide a way to run multiple isolated Python interpreters within a single process. Let’s dive deeper into this novel concept and discuss its advantages and potential use cases. What are Subinterpreters? At a high level, each subinterpreter in Python has its own distinct memory space and execution state.

HTML5 PostMessage Security: Protecting Cross-Origin Communication

HTML5 introduced a powerful feature called postMessage that allows secure communication between different origins or domains. While this functionality provides a convenient way to exchange data across frames or windows, it also poses potential security risks if not implemented correctly. In this article, we will explore the security considerations of using postMessage and discuss best practices to protect cross-origin communication. Understanding postMessage postMessage is an HTML5 feature that enables asynchronous communication between different browsing contexts.

What is GitHub CoPilot?

GitHub Copilot is an AI-powered coding assistant developed by GitHub in collaboration with OpenAI. It uses machine learning algorithms to assist developers in writing code by suggesting code snippets based on the context of the code being written. This powerful tool has the ability to autocomplete code, provide inline documentation, and generate entire functions, making coding easier and more efficient. GitHub Copilot is built on top of OpenAI’s GPT-3 language model, which has been trained on a vast amount of data from a variety of sources, including code repositories, documentation, and programming languages.

Writing a Basic Burp Extension in Python

Burp Suite is a popular web security testing tool that helps you secure web applications by testing and validating vulnerabilities. It’s a comprehensive platform for performing security assessments on web applications, and its extensibility is one of its key features. Burp Suite extensions are add-ons that allow you to customize and extend the functionality of Burp Suite. These extensions can be written in any JVM-compatible language, including Java, Python, and Ruby.

Context Managers in Python

Python is a powerful and versatile programming language that offers many features to help developers write clean and efficient code. One of these features is the use of context managers. In this blog post, we will take a closer look at what context managers are and how they can be used to simplify and improve your Python code. A context manager is an object that defines the methods enter() and exit().

Content Security Policy (CSP)

Content Security Policy (CSP) is a security measure that helps protect web applications from various attacks, including Cross-Site Scripting (XSS) and data injection. CSP works by specifying a set of Content Security Rules that dictate what resources are allowed to load on a page. This can be used to whitelist trusted sources of content, or to block untrusted content entirely. One advantage of Content Security Policy is that it can help to prevent malicious code from running on a page.

Writing a Burp Extension in Ruby Part 1

Writing a Burp Extension in Ruby Burp extensions can be written in 3 languages - Java, Python, and Ruby. Since Burp is a java app, in order to write extensions in Python you need Jython and in Ruby you need JRuby. For this example, we’ll use Ruby. Step 1 - Downloading JRuby The first step is to download JRuby from https://jruby.org/download. For this example we will be using the latest - 9.
