Introducing CamScan: A New IP Camera Discovery Tool for Linux

Finding every IP camera, NVR, and DVR on a local network can be surprisingly difficult. Devices may advertise themselves through ONVIF or mDNS, expose only an RTSP service, use a vendor-specific web endpoint, or respond on an unexpected port. CamScan brings these clues together in one Bash-based discovery tool designed for networks you own or are authorized to test. The open-source project is available on GitHub at error0327/CamScanner . It is designed and tested around Kali Linux, while also including fallback package mappings for other supported systems where possible. What makes CamScan useful? CamScan does more than look for a single port. It combines multiple discovery and fingerprinting signals, then scores each host as a possible, likely, or confirmed camera device. This helps reduce noise while still surfacing devices that may not identify themselves in an obvious way. Scans a subnet, IP range, or individual host. Uses ARP discovery when available, with an Nmap p...

Ollama Voice Chat — A Local, Talking AI Assistant for Windows

  Ollama Voice Chat — A Local, Talking AI Assistant for Windows I’m excited to share my latest open-source project: Ollama Voice Chat — a simple but powerful local voice chat assistant that runs fully on your machine using open-source AI tools. It lets you talk to a Large Language Model (LLM) and hear its responses spoken back out loud — no cloud APIs, no monthly fees, and full control of your data. 👉 GitHub repository: https://github.com/error0327/ollama-voice-chat 🚀 What Is It? Ollama Voice Chat is an interactive client for Windows that connects to a locally running LLM (via Ollama), converts user speech to text, sends it to the model, and uses Coqui TTS to speak the replies. It includes an automated setup script to streamline installation and configuration. Instead of typing, you can talk to your AI assistant and get spoken answers — great for hands-free use cases, prototyping voice UIs, or just having a more natural interaction with your models. 🧠 Why This Matte...

Meshtastic on the RG35XX Plus: A Mesh Communication for Handheld Retro Devices

I’m excited to share my latest open-source project: Meshtastic_RG35XXPlus — a practical helper application that brings Meshtastic mesh communication tools to the Anbernic RG35XX / RG Cube handheld family. 🎮 Why? Because these devices have great displays, Python support, and network connectivity — ideal for lightweight field tools. ➡️ Source code and details: https://github.com/error0327/Meshtastic_RG35XXPlus ( GitHub ) What Is Meshtastic? Meshtastic is an open-source, decentralized mesh networking platform built on inexpensive LoRa radios. It lets you send messages (text, telemetry, and small data) over long distances without relying on cellular or internet networks. ( GitHub ) At the core, Meshtastic devices form a mesh network — where each node forwards messages to others, extending communication reach far beyond what a single radio could do on its own. ( Wikipedia ) Common use cases include: Outdoor expeditions (hiking, biking, camping) where cellular coverage is poor. ( Mesht...

ESP32-C6 Wi-Fi Logger with Browser GPS + Heat Map Dashboard

This project is an ESP-IDF firmware for the Seeed Studio XIAO ESP32-C6 that turns the board into a self-hosted, secure Wi-Fi scanning logger. It creates its own access point, serves a responsive HTTPS web UI, logs nearby Wi-Fi access points, optionally tags rows with GPS coordinates (provided by the client browser), and exposes battery status from the on-board LiPo input. The end result is a pocket Wi-Fi “survey” tool: scan, track, export logs as CSV, and generate a heat map view to visualize RSSI vs location. Project overview and feature set: :contentReference[oaicite:1]{index=1} What it does AP + Station mode so the device can serve the dashboard while scanning nearby Wi-Fi networks. HTTPS web interface using a bundled certificate/key for local secure access. Single scan and continuous tracking modes. CSV export for analysis and archiving. Persistent logging to SPIFFS at /spiffs/logs.csv . Battery monitoring via ADC with voltage/percentage/status sh...

M5Stick-C Wi-Fi Spectrum Explorer (and SSID Tracker)

I built a small firmware project for the M5Stick-C that continuously scans the 2.4 GHz Wi-Fi band , visualizes channel congestion as a histogram, and lets you drill into the strongest nearby networks (SSID, RSSI, channel). There’s also a lightweight tracking mode that estimates distance to a selected SSID using RSSI. Pocket-sized Wi-Fi visibility: quick scans and a clear spectrum view on the M5Stick-C. What it does Periodic active scans of nearby Wi-Fi networks across channels 1–13 . Histogram “spectrum” view showing how congested each channel is. Detail view listing the strongest networks with RSSI (dBm) and channel. Manual rescan on demand. Battery indicator with live percentage on screen. Tracking mode : lock onto an SSID and display RSSI + estimated distance. Spectrum view (channel congestion) The default screen is a simple histogram across channels 1–13. It gives an at-a-glance picture of where the band is crowded, so you can quickly s...

Evolving Security Practices: Embracing DevSecOps in 2023

Introduction:   In the ever-changing landscape of technology, cybersecurity remains a critical concern for organizations across industries. The need for robust security measures has given rise to the concept of DevSecOps – an approach that integrates security practices into the entire software development lifecycle. As we step into 2023, DevSecOps has become a pivotal strategy for organizations to ensure the security and reliability of their digital products and services. This article explores the significance of DevSecOps and the key developments in its implementation in 2023.   The Evolution of DevSecOps:   DevSecOps is an extension of the DevOps methodology, which emphasizes collaboration and integration between development, operations, and other cross-functional teams. In the past, security was often an afterthought in the software development process, leading to vulnerabilities and delays in addressing security issues. However, with the ...

Kubernetes Ingress with Nginx Example

Kubernetes Ingress with Nginx Example What is an Ingress? In Kubernetes, an Ingress is an object that allows access to your Kubernetes services from outside the Kubernetes cluster. You configure access by creating a collection of rules that define which inbound connections reach which services. This lets you consolidate your routing rules into a single resource. For example, you might want to send requests to  example.com/api/v1/  to an  api-v1  service, and requests to  example.com/api/v2/  to the  api-v2  service. With an Ingress, you can easily set this up without creating a bunch of LoadBalancers or exposing each service on the Node. Which leads us to the next point… Kubernetes Ingress vs LoadBalancer vs NodePort These options all do the same thing. They let you expose a service to external network requests. They let you send a request from outside the Kubernetes cluster to a service inside the cluster. NodePort NodePort ...
