Post-2024 news

Mainstream media failed to hold Trump to account over the course of the 2024 presidential campaign through "view from nowhere" centrism and false equivalencies between both campaigns.

Here is a list of news organizations, newsletters, and writers that are audience-funded and/or non-profits committed to independent and investigative journalism.

Rules

No centrist contrarians or right-wing authors

Hosted PAB setup

This document describes how to prepare hosted PAB deployment from scratch that can operate on Alonzo purple testnet.

The following required to be run on host machine to use PAB with contracts in hosted scenario on testnet (for 2020-11-05 PAB Release):

Cardano node connected to Alonzo testnet
cardano wallet connected to node
chain-index connected to node
PAB executable connected to node, cardano-wallet and chain-index

Note: we are using somewhat more involved setup with a bit custom docker compose, and wallet and chain-index being built from sources, but there is ready to go node+wallet docker solution available

My Context

My understanding of PCDM so far:

PCDM models repository objects, including the RWO/"intellectual work", a digital resource (surrogate or born digital), and binaries.
