    FREE Programming courses (Python, C, SQL and more)

    Free programming courses are available for languages like Python, C, and SQL. Using Chat GPT can be misleading for students who rely too heavily on it, as it may result in superficial learning and difficulties during real-world applications. Effective use of Chat GPT involves understanding its outputs and not solely depending on it. Programming curriculums should focus on teaching fundamental skills and preparing students for a career in the AI-enhanced environment.

    Firefox Just Killed Browser Fingerprinting (2025)

    Firefox 145 introduces enhanced anti-fingerprinting protections that reduce uniquely identifiable users from 65% to 20%. The new defenses block tracking through hardware details, fonts, processor cores, and screen dimensions. Initially available in private browsing and strict mode, these protections will eventually be enabled by default for all users. Fingerprinting allows websites to track users even when cookies are blocked by creating unique digital signatures from browser and device characteristics.

    How To Learn AI in 2025 (If I Started Over)

    Phishing detection, despite the existence of advanced AI models, still poses challenges. Learning multiple topics, like AI and cybersecurity, is recommended as it provides broader insights. The focus in AI has shifted from merely expanding language models to incorporating data for improved accuracy. However, large language models can still be easily confused. Beginners should start with introductory courses, practice hands-on tasks, and understand machine learning fundamentals. The rapid evolution in AI technology offers a chance for continuous learning. Privacy concerns, especially in platforms using AI, remain significant.

    OSINT tools to track you down. You cannot hide (these tools are wild)

    OSINT (Open Source Intelligence) techniques can reveal extensive personal information through free tools and APIs. The demonstration covers three levels of OSINT: basic Google searches, intermediate techniques using specialized tools like people search engines and phone number lookups, and advanced methods involving API exploitation and automation. Key techniques include diversifying search engines, using Android emulators for shady apps, leveraging government databases, and automating form submissions to extract voter records and personal addresses. The presenter emphasizes maintaining redundancy across tools and proper documentation through mind mapping to avoid rabbit holes during investigations.

    Linux for Windows?

    Windows Subsystem for Linux (WSL) allows you to run Linux distributions such as Kali Linux and Ubuntu directly on a Windows machine. It provides the ability to use Linux commands, run web traffic interception tools like Burp Suite, and execute password cracking with tools like Hashcat, utilizing GPU resources. Users can access both Linux and Windows file systems, leveraging the strengths of both environments seamlessly.
