Random Thoughts 7

[Borg]

A bunch of people in my office are getting moved to another building. I'm staying but someone decided that I have to move into the next seat over - probably because they didn't want to adjust their planned seating chart.

55 years this week Apollo 11 landed on the moon. With all the Space x crazy stuff plus the first Ariane 6 launch I wanted to compare footage.
Even today the 1969 footage is really amazing. The fact it is slow motion just adds to the coolness.
See the amount of debris? Wow.

Anyway, not worth a thread but certainly worth a mention.

Apollo 11



Space x last month.



Ariane 6 last week

I thought I had inadvertently walked into the NFL until I realized I was standing right in front of the men's room , with people desperate for a urinal.

Some good advice. Plan ahead.

Pretty bizarre, due to careless misreading. Free trial! Somehow, for a second, I thought it was a legal trial. Are they suing me for free? Then coffee kicked in.

Every year, scores of boaters travel the 6,000-mile route around the Eastern United States.

The Great Loop has been called the last great adventure in North America, a 6,000-mile journey from the Mississippi River to the Gulf Intracoastal Waterways, around Florida and then up the Atlantic coast, across the Erie Canal, and through the Great Lakes. In 2022, only 227 boats returned to their point of origin, “crossing their wake” and earning the privilege of flying the gold Great Loop burgee (flag). Most “Loopers,” traveling in boats at least 30 feet long, took about a year to complete the route. Omaha Nebraska’s Mike Straub completed the loop in just 91 days. He did the whole thing on a Sea-Doo jet ski.

I think retracing the Lewis and Clark expedition would be a great adventure.

Anyone know how to interpret a 'perimeter acre'?

Perimeter Acres

133,489.06

from: https://www.kptv.com/wildfires/

perimeter	perimeter acres
1.14	179.5
3.86	226.09
4.4	701
50.82	18432.12
147.43	84364.39

Plugging in the numbers from the above fires, I get an R² of 1.000 for a quadratic function: y = 2.1122x² +264.07x -474.36

where y is 'perimeter acres' and x is the perimeter, in miles.

A perimeter acre is probably defined as
$$\frac{\text{length of the wildfire's perimeter}}{\text{area of wildfire}}.$$

I'm guessing that "perimeter acres" means the area (near the perimeter) that is actually on fire, assuming the area in the middle is burnt out.

Then the average width of the burning area is approximately the "perimeter area" divided by the "perimeter length" (assuming the width is a lot smaller than the length).

Name	Perimeter length $p$ miles	Perimeter area $a$ acres	Estimated perimeter width $a/(640p)$ miles	Converted to yards $\times 1760$
Lemolo	2.14​	179.5​	0.13106​	231​
Ore	3.86​	226.09​	0.09152​	161​
Trail	4.4​	701.38​	0.24907​	438​
Larch Creek	50.82​	18432.1​	0.56671​	997​
Lone Rock	147.43​	84364.4​	0.89411​	1574​

The values seem plausible.

(For readers outside the UK and US, a yard is about one metre.)

Seems not to be defined at x=1, where you get a negative value.

A perimeter acre is probably defined as
$$\frac{\text{length of the wildfire's perimeter}}{\text{area of wildfire}}.$$

So it's 1/length? Length is like wavelength, and 1/wavelength is frequency, so....
What's the frequency, Docnet?

I agree, that this seems like a plausible answer.
But I suspect it is wrong.
I loosened up my Google search parameters and discovered this PDF of a 1976 document, where I found on page 64:

Figure 7.--Approximate​

area of wind-driven​

fires, using Anderson's​

double-ellipse formulae​

in appendix II. In​

this figure, the area within the approximate​

perimeter (acres) has​

been divided by the​

squared distance (in​

chains) from the point​

of origin to the head​

of the fire. Thus,​

this ratio decreases with windspeed while​

the area itself actually increases.​

where they use 'chain' as a unit of measure, and Anderson's double-ellipse formulae in appendix II looks to be a rabbit hole of maths.

Seems not to be defined at x=1, where you get a negative value.

At least it didn't include the square root of negative 1.

In any event, never mind.

 

[docnet]

So it's 1/length? Length is like wavelength, and 1/wavelength is frequency, so....
What's the frequency, Docnet?

The quantity perimeter/(surface area) is just a concrete measure of... perimeter per surface area (sorry for the redundancy, but it was so self-explanatory that I'm just so puzzled with your question.

If it helps, the quantity could be loosely interpreted as the "oscillation count" of the perimeter to measure how "wavy" or "curvy" the perimeter is. But there is probably no benefit in defining it using frequencies and wavelengths. The quantity would have a minimum value (corresponding to a circle) and no maximum value (corresponding to certain fractals).

In any case, it may not be the right interpretation of the data, continuing this tangent may not be helpful. I was just trying to offer an alternative.

• At 18, they ask for 5-year experience;
• At 50, you are too old to work;
• At 62, you are too young to retire.

So true, to complete the story:

- I notified management on April Fool's that I plan to retire on May 1st
- I retired on May 1st and
- I got to exclaim May Day! May Day!

As so many retirees don't know what to do in the days following retirement.

Retirement is NEVER what you expect it to be.

I wish you all the best and seriously hope you will!
I mean, if Taylor can.

Crowdstrike provides security add-on to Windows for businesses, not personal computers. Are you a business? Do you pay them to provide their service to you?

 

[pinball1970]

Honestly?

A little tongue in cheek yes, BUT there would be no more restrictions on practice and gigs.
If we have a gig in London or Scotland we have to set off 12ish so I have to book days off.
Certainly make things easier that way.

EDIT: The bassist is 68 and seems relaxed with his retirement and still doing music. Hopefully I can find similar.

 

[BillTre]

Retirement has kept me surprisingly busy.

Yes, he can jerk about global warming while touring the globe solo in his mega jet. Taylor did it.
Leason. Be more like Roger Taylor, not the other one.

I haven't had a car in a while. My gas is the only contributor. I see people avoid me, but only within a 100ft radius.
Edit: Just please leave the van. Down by the river!

It is a horrible, ugly, uncomfortable, old thing but we love it. Even when It broke down in Macclesfield when we had a gig in Derby! It is a re-done UK Royal mail van. We only take two vehicles if we are also supplying the PA as well.
I took this from vehicle 2 on way to Lakes.
