With the last of the major GCC 8 build issues of the DragonFlyBSD code-base resolved, this BSD operating system has switched to using this latest stable release of the GNU Compiler Collection by default.
This is a big default change for DragonFlyBSD as up to now its default compiler was using the several year old GCC 5. With the default move to GCC 8 comes many optimizations, particularly for newer Intel and AMD CPU microarchitectures. This is especially good news for AMD Zen "znver1" CPU users. There is also support for newer C/C++ language features and many other enhancements as we've covered over the past few years.
Article takes a look at ZFS, an advanced file system. It will discuss where it came from, what it is, and why it is so popular among techies and enterprise.

pkgsrc is now frozen. Please use this opportunity to test pkgsrc bootstraps on your favourite esoteric OS or architecture, view the pkgsrc-bulk mailing list and fix some low-hanging fruit, and help them make this a great release.
If everything goes well there will be cutting the release some time over the weekend.
