Space junk. And who pays?

I found this interesting. We had another bit of space debris return to earth recently. Scientists suggested it would burn up on reentry and thus didn't plot an exact course for its de-orbit. 

It did not burn up. It did hit a house on the west coast of Florida and caused some amount of damage to the house and the surroundings. 

The homeowner talked with the insurance company about repairs, and were told that they'd have to pay the deductible - and that would not cover some of the other damage. 

This was not something that happened to the house due to an issue inside. This was not a natural disaster. And yet, insurance told them "sorry."

And then there was a complicating factor that the debris in question was part of a European space agency experiment. Which may have made this an international issue. But since it was attached to the ISS (which is under nasas purveyance), nasa agreed to cover at least some of the costs. 

But it leads to much bigger questions. Can we accurately predict what will happen with these things? Who is responsible? What if it was a private company's satellite? What if people were actually harmed? 

There's a lot of junk in space, and we need to be planning to do something with it.

Deep space transmission.

You may recall that the psyche mission had a major component that was an ability to send larger amounts of data from longer distances. 

Until now, we've been using radio waves to transmit data from longer distances (though we have compressed data from shorter distances, which ups the amount of data that can be returned). This technology allows us to use lasers to achieve the mission parameter, about 1 MBps. 

While it was still "near" to earth, they transmitted a prerecorded cat video with no data loss. 

Now, they are transmitting telemetry and "new" data from a distance about 1.5 as far as the earth to the sun … and achieving an astonishing 25 MBps. 

It's exciting. And opens up new possibilities for deep space communication.  

It's a function of the equipment used and distance, but for context, Apollo missions to the moon had a latency of about 3 seconds. This would be essentially real time.

And now this

I would posit that this is the very reason why those in power don't give two wits about climate change. It doesn't affect them; only the poor people who they can't be bothered to help. 

A win for workers…

Two things happened this week that are welcome news: salaried employees making around $58k or less will be due overtime if their hours exceed 40 in a week. It stops organizations from taking advantage of salaried employees in the middle management group. 

And then there was the decision to do away with non-compete clauses, meaning employees are free to leave and go and work elsewhere without consequence. 

Companies HATE this and are suing to stop it. In so many words, companies are saying their work is so important and so secret that they have to prevent employees from leaving; and rubbing salt in the wound by saying "we don't care about you - only our profit!"

Here's to hoping things continue to tilt in favor of the workers…

That pesky “law of unintended consequences”

The state of Florida wanted to crack down on immigration and thus caused many migrant workers to leave, and left the farmers in the state without workers to work the fields. 

So as this example points out, strawberries are rotting because they aren't picked. And the state says that's because they're not hiring the right people. 

Which are…. Who, exactly? 

And the net result is that the cost of doing business goes up - and consumers will have to pay more just to keep the farm open.

Bitchin' Dave's Newsletter - Apr 23

 Dave’s Musings

In the "we can be better" category, there was a story about a fast food worker who didn't miss a day of work in 27 years (and by the way, that's one of those things that bugs me; sometimes you're sick and you really should stay home rather than infecting those around you and handling food). To say thank you, the owners of the franchise gave him some stupid things (like a pen and a roll of lifesavers?).


While he was humble about it all, he posted a video about his gifts, and it went viral. And then someone setup a group collection, and they raised rather a lot of money - enough for him to buy a house.


Its great that people stepped up to help, and that there is a kind of happy ending. But it bothers me that the guy worked - loyally - for nearly 3 decades and got no reward for doing so, and could not afford a house on his salary in all that time.

The chief of SETI was asked about any evidence of aliens, and he emphatically said there isn't any. The attached article is interesting and details out his comments. Its worth a read.


One of the more interesting things he suggests is a thought experiment about the vastness of the universe and our ability to traverse it.

He notes one other thing: its still statistically possible that there is life out there, we just haven't found evidence of it - yet.

While its simply theoretical research for now, there's a study which suggests placing reflective materials on various surfaces can cool the ambient temperatures in cities.


But what's unique about this is the general simplicity of the design. The reflective surfaces could include the reflectors used in roadway design (those little yellow reflectors you see); simply positioning a mirror inside these devices could reduce the temps by around 5F.


I can't wait to see this being applied.

There was an item that made the news cycle a few weeks back about how Disney was revising the "Disability Assistance Pass" at the theme parks.


For context, the DAP is a means for people with certain types of disabilities (say autistic individuals who can't stay in line) to essentially hold a spot in a virtual queue to make waiting an easier process.


I should note that until about 2016, there was another process that essentially gave guests with disabilities zero wait time. But it was changed because too many guests were abusing the system - especially 3rd party guides who were getting paid to bend the rules for entitled people.


As it turns out, there are still too many people taking advantage of the system in order to get to the front of the line. So Disney has altered the policy again, and have threatened lifetime bans for those that abuse it. Make no mistake, Disney knows exactly who these changes target, and its a warning to them.


A navigational buoy off the coast of the Florida Keys broke free and rode the Gulf Stream up to Scotland. 

It wound up on the shore, along with some other world travelers.

It's crazy how our oceans work, isn't it?

One Little Spark … 


You could certainly spin this story to be more about greed, but its hard to overlook the overtones.

The basic story is that there's an older cemetery for black, mostly enslaved people, outside of Atlanta - one which has multiple generations dating back to before the civil war.  A developer bought the land and wanted to relocate the bodies to elsewhere. Legal action ensued, and the developer agreed to leave the cemetery in place, and to maintain it, and give the public -  especially the family - access to it.

Only, he fell short of his promises and blames the HOA and the families for lack of access and maintenance.  They are suing to rectify the situation.

What I find off-putting is how easily this developer just moves on when there's no money to be made. And worse, the people who are afflicted are ignored because they aren't able to help him financially.
