a very common use case for regexes is to find matches that are preceded or followed by some context. a classical example being all lines that end with ‘a’. this requirement is usually expressed with a lookahead, where upon finding an ‘a’, you look ahead to check if it’s the end of the line. in a backtracking engine, this is very easy to implement - you just duct-tape the logic that checks the next character, but in a DFA-based engine, this is impossible because you cannot report “the match is here” if the next character is not even known yet. and by the time you know the next character, the position information is lost, so you can’t report the match retroactively (well, unless the distance is fixed of course..).

While layoff memos focus on who’s being let go—CEOs like to lead with the heart, after all—it’s vital to understand who’s kept their jobs. Are these mostly technical people? The folks with soft skills and deep relationships that are hard to replace? ServiceNow CEO Bill McDermott emailed me a brief on Friday about its blueprint for agentic business that states: “When intelligence is abundant, the scarce resource is everything surrounding it: the enterprise context that grounds AI in reality, the governance that makes it safe, and the execution infrastructure that turns insight into action.” Does that make the case for more people? No. But it does suggest that top-level cuts don’t always turn out as planned.
