Guys my current computer is broken, it's no longer turning on unless the charger is plugged in. Pretty sure the battery has blown. It's 3 years old and I'm thinking of buying a new one or maybe I should replace the battery, not sure. 🤔 Any advice on what to look for when purchasing a new laptop or should I focus on getting a new battery?

The official OWASP Top 10 list has evolved. In this video, it breaks down every single web application vulnerability from the latest OWASP Top 10 (2025) list in a fast-paced, straight-to-the-point format. Whether you are an aspiring ethical hacker, a web developer looking to secure your code, or preparing for a cyber security exam, understanding these 10 critical security risks is absolutely essential. It will go through the core concepts of each vulnerability, look at how cybercriminals exploit them (like SQL Injection, IDOR, and Supply Chain attacks), and explain exactly how to mitigate and fix them.

If you're new to Linux, this is the perfect place to start. And if you're a seasoned Linux master, I bet there's still one you don't know.

In this video, you'll build a Hacker Dropbox, a device that can be dropped into any network and give you remote access. This can pretty much be any device, including a Raspberry Pi…which is what will be used. And no….it’s not using VPN, it’s ZTNA (Twingate) which is much more secure and easier to setup. Why do this? If you’re like me, you are by default the helpdesk support of every person in your life friends, church, parents, grandma…and I need a very quick and easy way to remotely access these networks…even when I don’t know the subnet info. This is where the Hacker Drop box comes in handy, operating as a magic device for remote IT support. It also doubles as a penetration testing tool, giving pentesters easy access to a remote network in seconds.
