The wreath of the aurora circling the earth's poles are directly coupled to the solar wind.

From the 'outer-planets' the earth, mars, and venus all appear to be orbiting INSIDE the outer atmosphere of the sun.

That same atmosphere or "heliosphere" extends 100 times further than the orbit of the earth from the sun where it encounters the 'bow-shock' of interstellar space.

So in some sense we 'inhabit' the sun.

A very powerful podcast.

If Christians (evangelical or otherwise) can move the Republican Party away from the deep dark place it now finds itself in then that will make that party a proper party in this country and the Christians can take credit for helping to heal the divide we find ourselves in.

If Christians who are not Republican listen to this podcast and reach out to those who are Republican, not trying get them to switch to the Democratic party but, to support their efforts inside the Republican party then this divide that we find ourselves in will close that much faster and we can as a country can move forward together.

People of all political and religious persuasions should applaud what this young mother is thinking, doing and feeling.

Wow, can't help but imagine that celephod is 'checking-out' the ROV with the same intensity as the folks (humans) watching it are.

If/When we (as a species) ever come to recognize and accept and cherish our fellow sentient beings we share our biosphere with then we will have 'arrived', and realize "WE ARE NOT ALONE" in the cosmos.

To Paraphrase Paul Simon:

"STILL LEARNING AFTER ALL THESE YEARS"


We all (all of us) only have a single tool to apply in our analysis of reality. Failure to take into account the limitation of that tool goes a long way toward explaining our current failure to communicate among outselves.

When we wield this single tool in a place (bubble) that only contains voices of a certain kind then the outcome can be anything we want it to be.

To move forward we need to expand our personal 'bubble-echo-chambers.

And a quote from the article:

"... In the way that a person notices her body only once something goes wrong with it, we are becoming conscious of the role that Latourian networks play in producing and sustaining knowledge only now that those networks are under assault ..."

Do You Have and/or Use a P2P iOT device? (The answer is probably YES!)

VERY SHORT VERSION:

Read, Understand, ACT on the content of the blog post from KrebsOnSecurity.COM (i.e. LOOK AT YOUR iOT devices and compare their vendor to the list at the URL)

https://krebsonsecurity.com/2018/10/naming-shaming-web-polluters-xiongmai/

SHORT VERSION

Make sure you TRUST the vendor you purchase an iOT device from, and there as so many these days.

It is likely we all have such devices.

I have ONE SUCH device also and it is called Amazon-Alexa. I hope that all other iOT devices in our house are permanently OFF AND/OR disposed of. I got a weather station for Christmas that contained a device you plugged into your router and it would communicate with the display panel weather information it gleaned from the national weather service (or some other service that then got it from the NWS). I NEVER EVEN TOOK IT OUT OF THE BOX

NOTE: Almost NO ONE these days has an internal home server that takes the place of the external cloud and many iOT devices are not even capable of using such internal home servers anyway. So that is NOT A SOLUTION.

LONG VERSION

The characteristics of such a device are that you can 'manage-it' from anywhere you happen to be from your smartphone/tablet/computer.

In almost ALL cases such management requires a 'Cloud-Connection' so that basically your smartphone/tablet/computer communicates with the cloud and the cloud communicates with your device for you.

So --- how can this be since no iOT device in your home or for that matter NO DEVICE in your home actively has an open port to the outside net ---

OK --- here is how --- the iOT device is on a regular schedule where it "pings/connects-to" the cloud for instructions on what should be done and if you via your smartphone/tablet/computer have sent new instructions they are sent to your iOT device.

AND ---- here is the punch line --- This type of iOT device MUST have, these days a super good security system so some random process can not 'listen-in' on 'connect-to' requests from the iOT device and the cloud and take over the conversation and make the iOT device part of a BOT-NET.

Above is the URL from the KrebsOnSecurity.COM post that goes into this for one particular company who sells its devices a 'white-label-products'. This means there is NO TELLING HOW to go backward and even the companies selling these under their own brand name may not know what is really going on.
