Signing Git commits

Why

Because after reading this blog post (sent by my dear friend @hugobessaa) I got paranoid. It's a little effort that can avoid a lot of trouble.

The problem

1. User changes the commit author using the --author option
2. The commit then introduces a new bug (blaming the new author)

Here's how to install PostgreSQL and have it run automatically at startup, on an Ubuntu 10.04 virtual machine using Vagrant. This took me a while to figure out:

Add the default lucid32 base box to your vagrant, if you haven't already:

host> vagrant box add lucid32 http://files.vagrantup.com/lucid32.box 

Now make a new lucid32 virtual machine and install postgresql on it:

class Automaton:
    def __init__(self, nstates):
        self.transitions = [{} for i in range(nstates)]
        self.accept_states = [False] * nstates

    def register(self, source_state, char, target_state):
        self.transitions[source_state][char] = target_state

    def register_accept(self, state):
        self.accept_states[state] = True

WHEN WILL BROWSERS BE COMPLETE?
A short exploration into the end game of web browsers.

This article may seem to be about bashing Google but it isn't. It's just about
reflecting on the current state and how much longer we should see ourselves
here.

So what is the Web? Well we can agree the Web is a conglomerate of standards
proposed by the W3C. So what do those standards define?

##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

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

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.
