On the frontiers of biology: plant communications
It's often assumed that plants boring, sedentary, and solitary organisms, but new research (or old research reexamined) changes that. Plants communicate, the mount defenses against predators; they seemingly act in concert with one another, though other hypotheses call into question the intentionality of such communication.
Quanta magazine has a recent article titled "The Secret Language of Plants" detailing some new research.
PBS's Nature has a full episode online- What Plants Talk About.
Both provide a fascinating look into a normally overlooked part of our world.

Make a calendar entry for 21 AUG 2017
A total solar eclipse will cover much of North America as shown on this map. Hopefully the weather will be clear where I am. Just have to figure out what kind of photo equipment I'll need.

Cheap stratum 1 NTP server
A cool project for an IT person or someone with a Raspberry Pi: build a small stratum one NTP server.
Enterprise NTP servers with GPS modules can cost thousands. A Raspberry Pi based NTP server is a small form factor inexpensive way to get GPS based NTP time. Other good uses, especially at small sites, remote offices, or co-location facilities:
- DHCP
- Out-of-band/management network
- Performance monitoring, troubleshooting, packet capture
