No, your cryptocurrency cannot work

Whenever the topic of Bitcoin's energy usage comes up, there's always a flood of hastily-constructed comments by people claiming that their favourite cryptocurrency isn't like Bitcoin, that their favourite cryptocurrency is energy-efficient and scalable and whatnot.

They're wrong, and are quite possibly trying to scam you. Let's look at why.

What is a cryptocurrency anyway?

There are plenty of intricate and complex articles trying to convince you that cryptocurrencies are the future. They usually heavily use jargon and vague terms, make vague promises, and generally give you a sense that there must be something there, but you always come away from them more confused than you were before.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

# I Pledge To Be Better 

I want our industry to be a safe, welcoming and inclusive place for everyone, regardless of
their gender, abilities, skin color, sexual orientation, age, class, neuro-diversity or any other attribute.
I acknowledge that this is not currently the case, and will do my best, to the extent that I can
afford to dedicate to this, to help make ours a better community and industry.

I value the diversity of perspectives that people with different backgrounds bring to the table.
I will call out exclusionary practices, behaviors or cultures and see how, together, we can perhaps
reshape them to be inclusive and supportive instead.
