    Ruby 2.7 released
    Over the holiday week, we missed the announcement of Ruby 2.7 on December 25. It is the most recent release of the Ruby programming language and was more than a year in development. There are quite a few new features including experimental pattern matching for case statements (more information can be found in these slides), a new compaction garbage collector for the heap, support for separating positional and keyword arguments, and plenty more.

    [$] A medley of performance-related BPF patches
    One of the advantages of the in-kernel BPF virtual machine is that it is
    fast. BPF programs are just-in-time compiled and run directly by the CPU,
    so there is no interpreter overhead. For many of the intended use cases,
    though, "fast" can never be quite fast enough. It is thus unsurprising
    that there are currently a
    number of patch sets under development that are intended to speed up one
    aspect or another of using BPF in the system. A few, in particular, seem
    about ready to hit the mainline.
