The RAM Shortage Comes for Us All
Memory price inflation comes for us all, and if you're not affected yet, just wait.
I was building a new PC last month using some parts I had bought earlier this year. The 64 Gigabyte T-Create DDR5 memory kit I used cost $209 then. Today? The same kit costs $650!
Just in the past week, we found out Raspberry Pi's increasing their single board computer prices. Micron's killing the Crucial brand of RAM and storage devices completely, meaning there's gonna be one fewer consumer memory manufacturer. Samsung can't even buy RAM from themselves to build their own Smartphones, and small vendors like...

Why doesn't Apple make a standalone Touch ID?

I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in.
But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an Apple Magic Keyboard with Touch ID, rip out the Touch ID, and install it in a 3D printed box, along with the keyboard's logic board.
HackRF Pro Receive Sensitivity and Noise Figure

In the HackRF Pro specifications we’ve mentioned improved RF performance compared to HackRF One. Now that we’ve finalized any last tweaks to the RF front-end and production is well underway, we’d like to share some more details about the improvements.
One key metric for radio systems is sensitivity, which measures the minimum signal strength that a receiver can detect. However, for software defined radio hardware, sensitivity is difficult to define in a useful way as it changes depending on the modulation scheme in use and even the software implementation.
Instead we can look at noise figure: this measures the degradation in signal-to-noise...
How to Install Kali Linux in VirtualBox: Complete Setup Guide
Setting up Kali Linux in VirtualBox gives you a full penetration testing environment without touching your main operating system. You can test security tools, practice ethical hacking techniques, and learn cybersecurity skills in a completely isolated environment. If something breaks, you simply roll back to a snapshot. Your host system stays untouched. This guide walks […]

Types of Shell in Linux: Understanding Your Command Line Options
When you open a terminal on Linux, you’re conversing with a shell. That’s the program sitting between you and the operating system kernel, translating your commands into actions the system understands. Different types of shells in Linux exist because developers have different needs and priorities. Some Linux shell types prioritize scripting power, others focus on […]
The Linux wget Command – Linux Download Command
The Linux wget command is a command-line utility that downloads files from the internet using HTTP, HTTPS, and FTP protocols. It’s designed to work non-interactively, meaning it can run in the background while you’re logged out—making it perfect for retrieving large files, automating downloads in scripts, and handling unreliable network connections. Most Linux distributions include […]
Soldering Workshop in Mathematics and Science High School (PMG) in Pazardzhik
