"It's a place of extremes, invisible to our eyes, but now revealed in extraordinary detail," said Ashley Barnes, a European Southern Observatory astronomer who helped obtain the new data, in a statement.
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..).

If you want something fully split with thumb clusters and a columnar layout but that’s a little less minimal than the Zsa Voyager— and wireless to boot — the Advantage 360 from Kinesis, makers of the popular Advantage 2 is a good one to check out. It looks like it comes from an ‘80s-era IBM office, but is somehow also from the future. The tenting goes from low to intense and the key well curves concavely to meet your fingers where they naturally land. The 360 is per-key programmable, works with layers and has four macros keys.
