GNU Guile 2.2.0 released

Linux Weekly News - cs, 2017-03-16 18:20
The GNU Guile project has announced the release of Guile 2.2.0, which is an implementation of the Scheme Lisp dialect. "More than 6 years in the making, Guile 2.2 includes a new optimizing compiler and high-performance register virtual machine. Compared to the old 2.0 series, real-world programs often show a speedup of 30% or more with Guile 2.2. Besides the compiler upgrade, Guile 2.2 removes limitations on user programs by lowering memory usage, speeding up the "eval" interpreter, providing better support for multi-core programming, and last but not least, removing any fixed limit on recursive function calls. Not only does Guile 2.2 run fast, it also supports the creation of user-space concurrency facilities that multiplex millions of concurrent lightweight "fibers". See https://www.gnu.org/software/guile/news/gnu-guile-220-released.html for pointers to promising experiments."

A new bcachefs release

Linux Weekly News - cs, 2017-03-16 16:30
Kent Overstreet has announced a new major release of his bcachefs filesystem. Changes in this release include whole-filesystem encryption, backup superblocks, better multiple-device support, a user-space filesystem checker, and more. "We can also now migrate filesystems to bcachefs in place! The bcache migrate command takes an existing filesystem, fallocates a big file in it, creates a new filesystem (in userspace) on the block device but using only the space reserved by that file it fallocated - and then walks the contents of the original filesystem creating pointers to all your existing data." There is an on-disk format change, but there's a chance it's the last one.
