Linus Torvalds tells kernel devs to fix their regressive fixing
Linus Torvalds has given the Linux kernel development community a bit of a touch-up, after finding some contributions to Linux 4.18 complicated the kernel development process.
In his post announcing release candidate 2 of Linux kernel 4.18, Torvalds mentioned “some noticeable filesystem updates, particularly to cifs.”
“I'm going to point those out, because some of them probably shouldn't have been in rc2. They were ‘fixes’ not in the ‘regressions’ sense, but in the ‘missing features’ sense.”

Why data centers need log management tools
Even though systemd is a common logging method, rsyslog offers more features. One main capability is being able to write log messages to a specific database. You can also configure rsyslog logs on one main server for centralized access.

Systemd v239 released
Systemd v239 has been released with a long list of changes; click below for the full set. "A new system.conf setting NoNewPrivileges= is now available which may be used to turn off acquisition of new privileges system-wide (i.e. set Linux' PR_SET_NO_NEW_PRIVS for PID 1 itself, and thus also for all its children). Note that turning this option on means setuid binaries and file system capabilities lose their special powers. While turning on this option is a big step towards a more secure system, doing so is likely to break numerous pre-existing UNIX tools, in particular su and sudo."
