Emulating Raspberry Pi 4 with Qemu

Just a quick update before we dive in: what we're actually doing here is running Raspberry Pi OS (64-bit) on a QEMU virtual ARM setup. This isn't full-blown hardware emulation of the Raspberry Pi 4, but more about creating a virtual environment for the OS. It doesn't mimic all the specific hardware features of the Pi 4, but it's pretty useful and great for general testing. I turned to this solution mainly to extract a modified sysroot from the Raspberry Pi OS, something not readily available in other resources. For those looking into detailed emulation of the actual Raspberry Pi 4's hardware in QEMU, check out this link for the latest updates: https://gitlab.com/qemu-project/qemu/-/issues/1208.

Hope it helps! :D

Shortcomings: No GUI yet, only console.

Steps

The question: What is the best way we can use Google API via a service account in Github Actions? Answer: encrypt the credentials and decrypt during Action w/ a configured secret.

The credentials.json.gpg is originated from the credentials.json that can be downloaded from Cloud Console for the service account.
Encrypt it via: gpg --symmetric --cipher-algo AES256 credentials.json - Note the password used, as it will be added as a secret in this repo to be used for decoding the file and accessing Google APIs.
Update the credentials.json.gpg file in this repo using the contents of the newly created credentials.json.gpg, commit and push.
The password used should be added as a secret, e.g. the GOOGLE_API_PW secret in the github repo

Then, in the Github action or script, call gpg to decrypt and write the unencrypted file:

#!/bin/sh

Running into this error message when trying to run a mosh server on macOS Catalina? The steps below should solve the problem which is most likely either a $PATH and/or firewall issues.

command not found: mosh-server
Connection to X.X.X.X closed.
/usr/local/bin/mosh: Did not find mosh server startup message. (Have you installed mosh on your server?)

1. Install Mosh

Raspberry Pi on Internet via reverse SSH tunnel

HackerNews discussed this with many alternative solutions: https://news.ycombinator.com/item?id=24893615

I already have my own domain name: mydomain.com. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet). I wanted to be able to access these apps from public Internet. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. ngrok would work but the free plan is too restrictive.

I bought a cheap 2GB RAM, 20GB disk VM + a 25GB volume on Hetzner for about 4 EUR/month. Hetzner gave me a static IP for it. I haven't purchased a floating IP yet.

Note: everything here is pretty specific to my usage/accounts and not written for public use... You'll probably have to tweak a bunch of stuff.

##Weechat+Arch Linux+Tor ###A Quick Guide for Anonymous and Pseudonymous irc I'm going to assume you know what irc is, and generally how it works. If you haven't gotten that far watch a youtube video and try out some of the commands on an irc webclient somewhere. On Arch Linux to install Weechat you can run sudo pacman -S weechat or you can download it from the official website at http://weechat.net/download/.

You can also install Tor from the official repositories, but If you are going to be making multiple connections to irc networks and you want to keep your identities seperate, I would recommend installing the Tor Browser Bundle as well. This should be done from the Tor website, and you should check the GnuPG signature on the package before running it. The key they have been using to sign the packages with for the months that I have been verifying it i
