    Transforming a Disposable Vape into a Functional Web Server

    A creative hardware project successfully repurposed a disposable vape's PY32F002B microcontroller (24MHz ARM Cortex-M0+, 24KB flash, 3KB RAM) into a functional web server. Using semihosting communication, SLIP protocol for networking, and the uIP TCP/IP stack, the project achieved 20ms ping times and 160ms page load times through careful optimization including ring buffers. This demonstrates the potential of transforming resource-constrained everyday electronics into versatile computing devices.

    'IT manager' had never heard of a command line

    A tech support story about an IT manager at a tax office who didn't know basic technical concepts like command line or traceroute, despite being responsible for managing IT staff. The manager initially blamed the support technician for VPN connection issues but had to admit ignorance when asked to perform basic troubleshooting steps. The incident highlights the disconnect between management roles and technical knowledge in some organizations.

    This Website Runs on Disposable Vape

    A developer successfully hosted a website on a disposable vape's microcontroller using SLIP protocol. The initial implementation was extremely slow with 1.5s pings and 50% packet loss, but optimization with ring buffers improved performance to 20ms pings and 160ms page loads. The project demonstrates creative hardware repurposing and embedded systems programming.

    99% of Developers Don't Get Proxies

    Proxies are intermediary servers that act as gateways between clients and the internet, enabling anonymity, content filtering, load balancing, and bypassing geo-restrictions. The content explains forward vs reverse proxies, SSL termination, different proxy types (transparent, anonymous, elite), residential vs data center proxies, and SSL interception techniques that allow proxies to decrypt HTTPS traffic.

    How To Deploy a Full-Stack, Containerized Network Infrastructure Visualizer

    Atlas is a Docker-based network infrastructure visualizer that deploys in under two minutes and automatically maps all devices on your network. Built with Go, FastAPI, NGINX, and React, it scans Docker containers and local subnets to detect devices, retrieve OS fingerprints, MAC addresses, and open ports. The tool provides an interactive web dashboard on port 8888 for real-time network topology visualization and monitoring.
