WiFi Password Problem

A while ago, two of my Windows 10 machines suddenly were no longer able to connect to my Arris TG862 router via WiFi. Both are HP notebooks. Initially, the error message I got from Windows was:

"something has changed since you last connected"

It asked for the network key again and despite being the correct key it gave the error message:

"The network security key isn't correct."
"Please try again."

I tried everything that I could starting from deleting the WiFi credentials and replacing them. That did not work and I then moved on to the usual -- update/reboot. That also did not work. After that, I reconfigured a test router and that worked, but I still could not attach to the main router. Since then, I have been able to connect and I am not sure if this is because of a Windows update, something timing out or an update to the router firmware. It was unable to connect for at least a few days. I am not sure of the timing because I switched to ethernet adapters on the wired network so I could get back to work.

Anyway, if you encounter this problem, you are not alone and it can eventually be put back in order.

Knee-Jerk Gun Control Legislation

Many people insist on gun control legislation any time there is a shooting. It is politically hard to sell and as a life-saving measure it is a waste of time and resources. Time, resources, political capital and energy spent on a fruitless effort to control a significant minority of the population could instead be productively used to actually save lives. 

When we get news of a random mass shooting, it is as good a time as any to oppose senseless death. It is not such a good time to make rules for hundreds of millions of people. Maybe things should change, but not by angry actions in the heat of the moment. This is not the time to design public policy.

More than five thousand people die in the United States every day. If you save just one percent of those people, you save the lives of fifty people. You save not just fifty people today, but fifty people every single day -- more than ten thousand people a year. 

We already know things that will both save lives and make life better. Those things are supported by sensible evidence. 

Consider this: "Historically, every other developed nation has achieved universal health care through some form of nonprofit national health insurance. Our failure to do so means that all Americans pay higher health care costs, and 45,000 [annually] pay with their lives." -- Steffie Woolhandler, MD, MPH, staff physician and Associate Professor of Medicine at Harvard Medical School (HMS).

If you fight to get absolute no-brainer fixes like Universal Health Care you will save lives.

When it comes right down to it, it seems that people don't really want to help. It is every man for himself. They can help, but in practice they just won't.

The Second Amendment allows the people at the bottom to be armed against despotic oppression from the top. Gun control would be fine if done at a local level such that people could gain back control of their government if needed.

It is weird how invasive and tyrannical the U.S. Federal government has become. I think it would be a very bad idea to disarm while central government continues to expand its control. 

Install Docker on Window 10 error

I had a time of it attempting to install Docker on Windows 10. Here is what finally solved it for me: I shared drives:

Docker cannot run on Windows, apparently unless the drive where it is installed is also separately shared in the dialog shown above.
Every time I see a ridiculous error in the setup like this it makes me suspect the entire universe involved. Windows is by far the most used operating system on the planet and the fact that Docker cannot just set itself up or at the very least report why it is failing is troubling.
Some people have reported the problems but predictably, people jumping to help offer helpful generic suggestions rather than address the specific problem.
I do not know if my fix above will fix whatever ails your installation. It worked for me, but the fact that the installation program was unable to deal with this fundamental show-stopping item makes me wonder what else is broken.
