Magic words:
psql -U postgresSome 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)
If you're reading this, you probably suggested to somebody that a particular technical problem could be solved with a blockchain.
Blockchains aren't a desirable thing; they're defined by having trustless consensus, which necessarily has to involve some form of costly signaling to work; that's what prevents attacks like sybil attacks.
In other words: blockchains must be expensive to operate, to work effectively. This makes it a last-resort solution, when you truly have no other options available for solving your problem; in almost every case you want a cheaper and less complex solution than a blockchain.
In particular, if your usecase is commercial, then you do not need or want trustless consensus. This especially includes usecases like supply chain tracking, ticketing, and so on. The whole *p

Disclaimer: I wrote this script for my own personal use. Completely unofficial and unsupported by Vivaldi Technologies. However, others are welcome to use it at their own risk.
This script converts a Vivaldi browser Linux package into standalone, self-contained install. It lets you use the rpm and deb packages in a similar way to how people generally used the old Opera (Presto) tar packages—for quick testing, without committing to a full, system-wide install. This could be used for testing a specific setup or version, without touching the system wide settings (profile). It can also be used to create a portable (USB install) of Vivaldi that you could store on an external disk, for sharing between computers. A script that supports integration with the desktop environment is also provided.
Usage example:
sh standalone-vivaldi.sh vivaldi-snapshot-1.7.702.1-1.x86_64.rpm
When the script is done you will have a suitably version named directory.
Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.
This is enabled by adding the
ForwardAgent yes
option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.
