XOR (Exclusive OR) is a boolean logic operator defined by its truth table. It outputs 1 when inputs differ and 0 when they are the same. XOR has several interpretations: it can mean “exclusive or,” “not equals,” or can be seen as conditional inversion or parity operations. It possesses properties like commutativity, associativity, and identity with 0. Bitwise XOR extends these properties to integers, offering applications in cryptography, graphics, and error-correcting codes. In cryptography, XOR combines plaintext with a keystream for encryption. In pixel graphics, it allows for reversible drawing operations that are efficient in memory use. Overall, XOR is crucial to computer science for its simplicity and utility in various operations.

The IDE features an advanced REPL for code editing, debugging tools, and support for various libraries such as Matplotlib, PyTorch, and OpenCV. It aims to cater to both scientific and creative applications, supporting Python versions 3.8 and above. Currently compatible with macOS, Windows and Linux support is forthcoming.
TL;DR: Harper Reed shares a code generation workflow using LLMs, focusing on brainstorming, planning, and execution. He details two approaches: greenfield (new projects) and incremental (existing codebases). His steps involve honing ideas with a conversational LLM, creating detailed specs, and employing tools like Claude and Aider for execution. Despite the efficiency, he highlights limitations, such as solo work and potential environmental impacts of AI. He encourages skeptics to explore AI's benefits through resources like Ethan Mollick's book, aiming for a collaborative coding experience.
Catalog of Static Single Assignment (SSA) generation methods, detailing historical papers and approaches. SSA assigns variables once, improving compiler efficiency. Important papers cover various methods from 1980s to 2023, addressing phi functions, dominance frontiers, single-pass generation, and incremental SSA. Highlights include Cytron's minimal phi instructions, Brandis & Mössenböck's parsing approach, and recent works using reaching definitions. The author plans to add more resources and encourage contributions on SSA-related topics.
A.I. tools are enhancing coding efficiency, enabling software engineers to work more effectively without replacing them. While automation raises concerns about job losses, experts believe demand for software developers will continue, evolving rather than diminishing their roles.

TLDR:
In 2025, the top six AI app builders are:
Criteria for evaluation included prompt interpretation, automatic functionality setup, no-code usability, customization tools, and easy publishing. The landscape is evolving rapidly, with platforms focusing on enhancing user experiences in app development through AI.
OWASP helps web developers secure full-stack applications by highlighting common vulnerabilities. It offers a curated list of the top 10 vulnerabilities, serving as a crucial resource for understanding and addressing security risks. Key issues include Server-Side Request Forgery (SSRF), authentication failures, insecure design, and injection flaws. Developers are encouraged to implement logging, monitor software integrity, and stay updated on dependencies to enhance security. Understanding and applying OWASP guidelines significantly elevates a developer's ability to mitigate security threats in web applications.

New junior developers rely heavily on AI tools like Copilot for coding, producing functional code quickly, but often lack deep understanding of the underlying principles. They struggle to explain why their solutions work or to consider edge cases, indicating a loss of foundational knowledge. Unlike previous generations who engaged with resources like Stack Overflow, current practices favor quick fixes over thorough learning. To address this, developers should adopt a learning mindset with AI, engage in meaningful discussions, enhance code reviews to emphasize understanding, and build projects from scratch to deepen their knowledge. The challenge is to balance efficiency gained through AI with the necessity of solid coding fundamentals.
Debugging a highly protected iOS app involves dealing with advanced anti-debugging techniques, such as PT_DENY_ATTACH, which prevents debuggers from attaching, and random crashes that reboot jailbroken devices. The article outlines methods to bypass these protections, including setting breakpoints to intercept calls and using assembly code to directly invoke low-level functions. Additionally, it discusses challenges when injecting code, often due to app group configurations that get disrupted during code signing. Ultimately, the author successfully circumvents anti-debugging measures, attaches a debugger, and injects code, showcasing various strategies for exploring and modifying iOS apps under restrictive conditions.
TLDR: Set up a self-signed SSL/TLS certificate authority (CA) in Linux using OpenSSL. Generate a CA key and certificate, create a private key for the target domain (e.g., localhost), configure a certificate signing request (CSR), sign the certificate with the CA, and install the CA certificate to your OS or browsers. Follow specific commands for Ubuntu and Arch Linux.
traefik.me offers wildcard DNS for any IP, allowing access via easy URLs without configuration. It resolves domains like [10.0.0.1].traefik.me to the corresponding IPs, supporting HTTPS with Let's Encrypt wildcard certificates. Originating from the traefik.io reverse proxy, it's ideal for local Docker development, simplifying access to services with minimal setup.
TLDR; Chrome DevTools aids web developers in inspecting content, debugging, and monitoring performance. It features various tabs (Elements, Network, Console, Sources, Performance, etc.) for different tasks, such as inspecting page elements, viewing resource loads, debugging JavaScript, analyzing performance metrics (Core Web Vitals), and performing security audits. Key functionalities include editing content, throttling network speeds, running scripts, debugging memory leaks, and mobile emulation. DevTools also allows for code coverage analysis, and the use of hidden features like code search and screenshots.
NASA's 10 software development rules, aimed at embedded programming for spacecraft, prioritize avoiding programming pitfalls to prevent mission failures. Critiques highlight the limitations of these rules when applied to other contexts, such as compiler development, questioning their universality and adaptability to better languages. Each rule is examined critically, emphasizing the complexities involved, especially restrictions on control flow, loops, dynamic memory, function length, assertions, scope, error checking, preprocessor use, pointers, and compilation practices. Many rules, while promoting safety, may hinder readability, maintainability, and flexibility in programming.
