Thanks, good catch. You were right, the result was too far from the search box. It's fixed now: while you type, the results show up right below it.

The xz backdoor is basically his point in practice — that was a maintainer-trust compromise, not a hash collision.

Same trick as absorbing Markov chains — solve for the fixed point instead of summing the loop. Shows up in Leontief input-output models and PageRank too.
