Backing up Raspberry Pi

Tue, 16 Jan 2024 00:00:00 +0000

Why!?!? Link to heading

“Why!?!?” That’s what I was asking when my pi stopped working. After days of configuration and tinkering it just wouldn’t connect to the network anymore. I said to myself “Welp, I guess I’ll reinstall from scratch” and spent the next few hours installing and setting everything back up again.

Solution? Make a Backup using a Mac Link to heading

Obviously this is what I should have done from the beginning. Now what’s the “right” backup solution?

Installing OMV on Raspberry Pi

Tue, 16 Jan 2024 00:00:00 +0000

Open media vault allows you to run a NAS server on your raspberry pi. the easiest way to install it on your pi is to install the default “lite” version of the OS. That is the one with no “Desktop” and then run the following script:

wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/install | sudo bash

After that completes, you’ll also want to run this one:

wget -O - https://github.com/OpenMediaVault-Plugin-Developers/packages/raw/master/install | sudo bash

Give it a few minutes to run, and it should be accessible through the website at it’s ip address. You will then use the default username and password to log in. The default username is “admin” and the default password is “openmediavault”

Using Kotlin multi-platform for Android and iOS with firebase

Fri, 08 Dec 2023 00:00:00 +0000

So I just started a new app that is being built for Android and iOS. I’m building it using kotlin multi-platform (KMP). I started it by following a guide on jetbrains’ website. I started it by following this guide. https://www.jetbrains.com/help/kotlin-multiplatform-dev/multiplatform-getting-started.html#next-step after kdoctor said that my machine was ready for cross platform compilation I moved on to cloning this repo. https://github.com/JetBrains/compose-multiplatform-ios-android-template This app is using firebase so I had to integrate it into the app. I found this library which is a cross platform firebase library. https://github.com/GitLiveApp/firebase-kotlin-sdk Getting it set up was a bit difficult as the app kept crashing everytime I tried to use firebase for anything. I later found this guide but as it is the only one online, and seems to miss a few pain points that I found. https://medium.com/@carlosgub/how-to-implement-firebase-firestore-in-kotlin-multiplatform-mobile-with-compose-multiplatform-32b66cdba9f7 So I’m writing this to document my process and and pain points so that if anyone else wants to do this they can. Also, it should be noted that I started with the Authentication library.

QR codes

QR code text data formats Link to heading

So I’ve been playing around with QR codes. I wanted to know how to generate different data that can be read by a phone. I found the following page that describes how to format the data using text only.
https://github.com/zxing/zxing/wiki/Barcode-Contents

Save space using all caps Link to heading

QR codes have a special format for data that is in all caps and if you use it, the QR code will use less data. My understanding is that all you have to do to use it is to write the text in all caps (can include numbers and these symbols $, %, *, +, -, ., /, :, and space) and the QR code generator should automatically figure out how to represent it using less data. The downside is that some urls are case sensitive, so make sure to test the url before you print it.
“Alphanumeric mode is for the decimal digits 0 through 9, as well as uppercase letters (not lowercase!), and the symbols $, %, *, +, -, ., /, and : as well as a space.” Source: https://www.thonky.com/qr-code-tutorial/data-analysis

Installing Docker and Portainer

Mon, 18 Jul 2022 00:00:00 +0000

So I recently needed to install docker and portainer so that I could run a few services on my server.

Installing docker Link to heading

This is just helpful links for installing docker on ubuntu or lubuntu for me on lubuntu 22.04. the most important commands on that were:

sudo apt update && sudo apt upgrade -y
sudo apt install docker.io
docker --version

After that you should be able to to test that your installation is installed and running.

Ubuntu has a firewall enabled by default

Mon, 18 Jul 2022 00:00:00 +0000

So when setting up my ubuntu server. I was running into issues connecting from different machines on my local network. I ran a port scan using nmap to see that many ports were filtered. I tried many things, but in the end one simple command fixed it.

sudo ufw disable

Upgrading portainer

Mon, 18 Jul 2022 00:00:00 +0000

To make this, I followed the guide posted here. https://docs.portainer.io/v/ce-2.9/start/upgrade/docker The latest portainer at the time of writing is portainer version 2.14.1 please replace that string with the latest version when using the following commands.

sudo docker stop portainer
sudo docker rm portainer
sudo docker pull portainer/portainer-ce:2.14.1
sudo docker run -d -p 8000:8000 -p 9000:9000 -p 9443:9443 \
    --name=portainer --restart=always \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v portainer_data:/data \
    portainer/portainer-ce:2.14.1
