    Conway: Infinite work is less work
    Damian Conway writes about the power of infinite sequences in Perl 6.

    The sequence of primes is just the sequence of positive integers, filtered (with a .grep) to keep only the ones that are prime. And, of course, Perl 6 already has a prime number tester: the built-in &is-prime function. The sequence of primes never changes, so we can declare it as a constant: 
        constant p = [  (1..∞).grep( &is-prime )  ];
    Now we need to extract just the strong and weak primes.

    [$] Bcachefs gets closer
    When it comes to new filesystems for Linux, patience is certainly a
    virtue. Btrfs took years to mature and, according to some, still isn't
    ready yet. Tux3 has kept users waiting
    since at least 2008; as of 2018 its developer still said
    that it was progressing. By these measures, bcachefs is a relative youngster, having
    been first announced a mere four years
    ago. Development of this next-generation filesystem continues, and
    bcachefs developer Kent Overstreet recently proclaimed
    his desire to "get this sucker merged", but there are some
    obstacles to overcome still.
