Weather Radar
My dedicated weather monitor: An old 2004 Hewlett Packard Pavilion Desktop A744X Intel Pentium 4 running Ubuntu 16.04LTS and hardwired to an internet router. It displays local radar via 10News with three different possible geographical views and two NOAA GOES infrared satellite animations and one still from of the Gulf of Mexico. The page refreshes with updates automatically every five minutes. I leave it up and running all the time. I have another old computer with a sub woofer sound system and big HD monitor for movies and another for browsing and such. A fourth old PC with multiple hard drives serves as an archive and repository for personal data.

WHY I DO NOT EVACUATE OR GO TO A SHELTER DURING HURRICANES:
Currently my only drawbacks are the lack of hurricane shutters and a wooden roof. The original construction included concrete tiles on the roof. As a consequence the roof is supported by double the number of rafters for the extra weight of the tiles. I had my roof replaced with asphalt shingles in 2003 but the rafters provide the extra protection of a fallen tree. Hurricane anchors for the roof may still be required to keep it from becoming unattached during 150MHP winds. Always a possibility.
Most hurricane shelters DO NOT TAKE PETS. We have two cats. Once you enter a shelter they do not let you leave until the storm is over. I would go crazy with nothing to do and not knowing how my house survived the storm. My friend took his children to a shelter and brilliantly took a tent and set up inside the shelter for privacy.
My telephone is a landline. A real 1960s copper hardwire. When the power goes out and cellphones lose their connection my phone still works. It always has. My neighbors have similar houese and do not evacuate either. We all work together after the storm to help clean up and combine resources to provide each other with necessities. The rest of the time we pretty much leave each other alone. I like that. We are only two miles from the Gulf of Mexico but I am confident we could withstand a cat5 from the west at full force. Should the roof blow off we have a small hallway 3ft x 8ft. in the center of the house where we would literally "hunker down".
If there is a hurricane we will be home. Call us. When the power goes out there is nothing to do.

Dreams of Star Trek
Dreams of Star Trek.
Launched in September 1977 the Voyager program was a Grand Tour to study the outer planets. The Grand Tour would take advantage of an alignment of the outer planets discovered by Gary Flandro, an aerospace engineer at the Jet Propulsion Laboratory in the 1960s. This alignment, which occurs once every 175 years, would occur in the late 1970s and make it possible to use gravitational assists to explore Jupiter, Saturn, Uranus, Neptune, and Pluto with very little fuel. It took a year and a half to get to Jupiter, another year and a half to get to Saturn. The big planets were used to speed up the spacecraft and after Voyager passed Saturn it was moving over 39,000 mph.
It still is.
August 25, 2012 Voyager I entered interstellar space. It took 45 years just leave the influence of the solar wind. It is now 13 billion miles from Earth but still in the gravitational range of the solar system. Sedna, a dwarf planet discovered in 2003, orbits 90 billion miles from the sun taking 11,400 years to complete. Beyond that is the Oort Cloud, a theoretical cloud of predominantly icy planetesimals believed to surround the Sun to as far as somewhere between 50,000 and 200,000 AU (3 light years, 19 trillion miles).
So insteller travel is still way beyond our technology. Way beyond. Even "locally" we've discovered Jupiter has deadly radiation belts extending out 7 million kilometers from the planet making sight seeing possible only from a distance. It took Voyager II twelve years to get to Neptune. Interplanetary travel is also way beyond or technology.
Star Trek the dream is only that. Nothing more.
