1 UNIX source code legally available, DragonFlyBSD 4.8 released
===============================================================

 Some 25 years ago, [UNIX System Laboratories, Inc, dragged one of
 the main driving forces of UNIX, the Berkeley Software Design,
 Inc, to court] and sabotaged the most thriving software ecosystem
 witnessed so far. In the end, three files out of over 18,000 were
 removed due to possible copyright infrigement, Windows NT gained
 ground, Linux took off and the [Computer Science Research Group]
 was disbanded. This followed a licence change in v7, which
 forbade efforts like the famous [Lion's Commentary on UNIX]. How
 things have changed: [the source code for UNIX 8th Ed., 9th
 Ed. and 10th Ed. has been released publicly for everyone to read
 and learn].

 Skipping back to today, [DragonFly BSD 4.8 has just been
 released]. DragonFly began as a fork of FreeBSD 4.8 and is one of
 the most interesting operating system design efforts since the
 2000s, which among other things brought us the wonder that is the
 [HAMMER filesystem].

 Also, [this].
