Write the source down.
Every claim on this site, in every report we send a client, in every email we send a journalist, carries a named source and a date. We keep a public corrections log. We retract pieces that turn out to be wrong. We notice when our own opinions do not have a citation behind them, and we treat that as a problem to fix.
Ship the smallest thing that works.
The cheapest fast website is the one with the least code in it. The most reliable software is the software that does one thing. We default to plain HTML, plain CSS, server-rendered pages, and a database when we need one. We add complexity when the business needs it, not because the engineer is bored.
