I was replying to a comment quoting an official rule saying "no piece can be moved if that exposes or leaves its own king in check."

I was pointing out that that specific rule (read to mean that moving a piece pinned against a king is not allow) is not strictly necessary. Putting oneself in check is not allowed regardless of whether it's because you moved a piece that was pinned against your king or moved your king directly into the line of sight of an opponent's piece. These are the different "means."

As a sibling comment points out, "The only action you can ever take in chess is moving," so it's not particularly meaningful to say that the only way to put yourself in check is by moving.

Did you mean putting your opponent in check? In chess, you are not allowed to put yourself in check.

That's a consequence of not being allowed to put yourself in check (by any means).

Sometimes HN admins revive quality posts that didn't get much traction when they were first posted. When this happens, the timestamps are updated to make the post look new.

I can't say for sure whether this is what happened here, but it is a possible explanation.

The AI narration was off-putting, but the video footage was cool.

The dependency has just come out of the oven, so it's too hot and must cool down ;)

The MacBook Pro has had a 120 Hz screen for nearly half a decade. And of course, external displays can support whatever resolution/refresh rate, regardless of the OS driving them.

Not connector related, but I can't tell you how many people use time zones like PST year-round. The ST stands for "standard time," meaning not Daylight Saving Time. Right now, PDT would be appropriate.

The thing that kills me is that they could just say "PT" or "Pacific time" and be right, with less effort.

I always know what they mean, but it's wrong for more than half the year.
