  Their words

  Given the simplicity and speed of the algorithms in this post and the increasingly small deltas between successive algorithms, perhaps we are nearing an optimal solution.

  Buggy code usually causes outright test failures rather than being silently exercised inside tests that still pass.

  Their words

  a passing test can still execute buggy code if the bug is data-dependent, or if the test is not sensitive to the specific mistake in the code. But a lot of the time, buggy code only triggers failures.

  Comparing code coverage between passing and failing test runs is a cheap, effective way to localize a bug quickly.

  Their words

  Differential coverage is cheap to compute and display, and when it's right, it can save a lot of time.

  Debugging by reasoning backward from a bad state is inherently harder than reasoning forward from a known decision point.

  Their words

  One of the hardest things about debugging is running a program backward: there's a data structure with a bad value, or the control flow has zigged instead of zagged, and it's very difficult to understand how it could have gotten into that state.

  Writing a technique down, however basic it seems, is the first step to making it usable by everyone.

  Their words

  But writing a trick down is the first step to making sure everyone can do it: magic tricks can be basic but not obvious.

  The xz backdoor falls short of a Ken Thompson-style 'trusting trust' compromise, but comes a step closer to one.

  Their words

  We're not at trusting trust levels yet, but it would be one step closer.
