This web content discusses a real-life off-by-one error at a climbing competition in Europe. The author observes a subtle mistake in the placement of a hold on one side of the climbing wall, leading to a series of events where the issue is eventually discovered and fixed. The surprising part is that the climbers themselves had not noticed the error due to their optimized routes. The author reflects on the implications of this mistake and draws parallels to software development processes. The article concludes with a thought-provoking suggestion of starting with a new climbing route if a world record remains unbeaten for a long time.
