I’m still pissed at being forced to write in a passive voice in university. It’s awkward and carries less information, and makes it seem like nobody had any agency, science just kind of happened on its own and you were there to observe it.

I don’t know why anyone would prefer something like “An experiment was conducted and it was found that…”

To the much better “We conducted an experiment and found…”

Don’t go by any general rules. If you are unsure, take it home and sit down with your mushroom guide book and go through all the ways of identifying it and separating it from similar species until you are sure, or you give up and throw it away.

Just off the cuff here are a couple of examples that violate the advice given above, golden chanterelle is very spicy but perfectly edible; gyromitra esculenta (“false morel”) does not have lamelles, is supposed to be mildly flavoured, but is deadly toxic.

Oil and gas products account for 4.2% of Sweden’s exports. The gas exports alone almost rival those of dairy and eggs! Truly a petrostate if I ever saw one

People think it’s about Stallman being bitter. But it’s because GNU is a political project with the goal of total user freedom and control over their computer.
