I got my hands on the Raspberry Pi 5 few weeks ago, but I wasn’t able to use it for any purpose (more like I’m out of ideas). I mostly wanted to test the pihole in my network, but using Pi 5 just for that would be an overkill! So I got a Raspberry Pi Zero 2 W and installed Pihole natively. I wrote a post about it, feel free check-out. Also, when I ordered for the Raspberry Pi Zero 2 W, I forgot to order for a microSD, so I used the one in the Pi 5 which is a 64GB microSD card (I know it’s an overkill!). The entire Pi Zero is running just the Pihole with a 64GB microSD. ...

What is DHCP? DHCP (Dynamic Host Configuration Protocol) is a network management protol that automates the assignment of IP address to the devices that connect to a network and it also handles other network configuration parameters such as subnet mask, default gateway and DNS settings. Why do we need IP address anyway? Let’s take an example, You visit a coffee shop and connect to it’s Wi-Fi network. In doing so, you are essentially connecting to the shop’s router, which provides the internet connection. The router itself is connected to an internet service provider(ISP) via a modem or an antenna(in case of wireless broadband). ...

I just got my hands on “Raspberry Pi Zero 2W” today, let’s setup the Pi! Setup the Pi Make sure to use pi-imager for writing the OS into the microSD. Also use a router as well for easy-setup. Choose “Raspberry Pi OS 32-bit with no desktop environment” for the OS. Make sure to edit the username & password, SSID configurations, enable SSH using authentication, additonally note-down the hostname for ssh connection. Insert the microSD into Pi Zero after the OS installation. Plug in the microUSB into Pi and wait for few seconds to boot up. Head inside the router web-page and look into the connected clients. Identify the hostname (default:“raspberrypi”) and note-down the IP address. Let’s ssh into the Pi! ssh username@192.168.31.xxx Now you are inside the Pi, please update & upgrade the packages in it for further installations. ...

What is a static IP address? A static IP address is a fixed Internet Protocol (IP) address assigned to a device, which does not change over time. It serves as a unique identifier within a network, enabling it connect & communicate effectively. It is recommended to assign a static IP address to a device, which is always stationary & connected to the same network. Assigning static IP address on a frequently moving device will result in conflicts and blocks from either connecting to a router or accessing internet. ...

I don’t have enough knowledge about this when writing the documenation for setting up the pi-hole. I’m running this on a container in Raspberry Pi 5 8GB device (I know it’s an overkill but it’s for learning). Let’s use docker compose to run the pi-hole container Create directory for storing pi-hole configurations mkdir pihole-config cd pihole-config Create a file named docker-compose.yml touch docker-compose.yml Copy & paste this YAML configuration into docker-compose.yml services: pihole: container_name: pihole image: pihole/pihole:latest ports: - "53:53/tcp" # DNS Ports - "53:53/udp" # DNS Ports - "80:80/tcp" # Default HTTP Port - "443:443/tcp" # Default HTTPs Port - "67:67/udp" # using Pi-hole as your DHCP server environment: TZ: 'Asia/Kolkata' # Not setting one will result in a random password being assigned FTLCONF_webserver_api_password: 'pass' # If using Docker's default `bridge` network setting the dns listening mode should be set to 'all' FTLCONF_dns_listeningMode: 'all' volumes: # Pi-hole's databases and common configuration file - './etc-pihole:/etc/pihole' # Uncomment the below if you have custom dnsmasq config files that you want to persist. Not needed for most starting fresh with Pi-hole v6. If you're upgrading from v5 you and have used this directory before, you should keep it enabled for the first v6 container start to allow for a complete migration. It can be removed afterwards.

I noticed that I’m keep deploying many pages on Github and still looking at the documentation. So I decided to make a short documentation how to do it fast (keeping me from looking at the documentation) Create a hugo site in a specific directory you want: hugo new site sitename Replace the sitename with the actual sitename you want to create. Head inside the directory(hugo site) cd sitename git init Download a theme (we’re using holy theme here) git submodule add https://github.com/serkodev/holy.git themes/holy echo "theme = 'holy'" >> hugo.toml Let’s test it locally! hugo server Create a GitHub Repository Head inside the Repository on GitHub Goto Settings > Pages Change the Source settings to “GitHub Actions” Create a file named hugo.yaml inside .github/workflows mkdir -p .github/workflows touch .github/workflows/hugo.yaml Copy and paste the text into YAML file # Sample workflow for building and deploying a Hugo site to GitHub Pages name: Deploy Hugo site to Pages on: # Runs on pushes targeting the default branch push: branches: - main # Allows you to run this workflow manually from the Actions tab workflow_dispatch: # Sets permissions of the GITHUB_TOKEN to allow deployment to GitHub Pages permissions: contents: read pages: write id-token: write # Allow only one concurrent deployment, skipping runs queued between the run in-progress and latest queued. # However, do NOT cancel in-progress runs as we want to allow these production deployments to complete. concurrency: group: "pages" cancel-in-progress: false # Default to bash defaults: run: shell: bash jobs: # Build job build: runs-on: ubuntu-latest env: HUGO_VERSION: 0.144.2 steps: - name: Install Hugo CLI run: | wget -O ${{ runner.temp }}/hugo.deb https://github.com/gohugoio/hugo/releases/download/v${HUGO_VERSION}/hugo_extended_${HUGO_VERSION}_linux-amd64.deb \ && sudo dpkg -i ${{ runner.temp }}/hugo.deb - name: Install Dart Sass run: sudo snap install dart-sass - name: Checkout uses: actions/checkout@v4 with: submodules: recursive fetch-depth: 0 - name: Setup Pages id: pages uses: actions/configure-pages@v5 - name: Install Node.js dependencies run: "[[ -f package-lock.json || -f npm-shrinkwrap.json ]] && npm ci || true" - name: Build with Hugo env: HUGO_CACHEDIR: ${{ runner.temp }}/hugo_cache HUGO_ENVIRONMENT: production TZ: America/Los_Angeles run: | hugo \ --gc \ --minify \ --baseURL "${{ steps.pages.outputs.base_url }}/" - name: Upload artifact uses: actions/upload-pages-artifact@v3 with: path: ./public # Deployment job deploy: environment: name: github-pages url: ${{ steps.deployment.outputs.page_url }} runs-on: ubuntu-latest needs: build steps: - name: Deploy to GitHub Pages id: deployment uses: actions/deploy-pages@v4 Head inside the root directory of your sitename hugo git add -A git commit -m "deploying the sitename" git push origin main

What is nmcli? The nmcli means NetworkManager Command Line Interface. It’s command-line utility tool used for controlling NetworkManager and reporting network status. In simple terms, we use that to interact with network related devices. How to use it? I don’t have proper way to explain, but let’s learn it with a case-scenario: Connect to a wifi network: Turn on the wifi module: sudo nmcli radio wifi on List the available networks: sudo nmcli device wifi list In case, it didn’t display any network, please rescan the available network and list it: ...

Why Open Source? Well, why not? I like open source applications and I prefer using them over monopolized, propreitary or closed-source applications. I want to break the cyle and inspire people to use alternative and support FOSS in every possible way. besides I’m an open-source/FOSS enthusiast + a nerd (hehe) 1. droid-ify - F-Droid client with Material UI This is like a play-store for Open-Source applications. Finding the applications is a breeze! I have listed it because the downstream is easy after installing this application. ...

Key features No root required to remove the bloatware. Cross platform, meaning it’s accessible on almost all the platforms. Getting Started: Download the Universal Android De-bloater (UADNG) from the github release. Extract the Files in your custom location. Install the dependencies sudo dnf install adb This would be enought to run the tool, now let’s see how to use it! Usage: Enable USB Debugging in your android phone. (mandatory) Connect the device with the computer you are running the tool. Run the Universal Android De-Bloater. Well, this would be my goto page whenever I need to remove the bloatware from my device. ...
