(ech, jeeze) Talon;
That is quite the Page Topper.

Now;...I Learned Today:
Cover the windshield of my car with a beach towel.
Hold it in place with the wipers.

This allows me to peel the towel and any frost and
or ice that has formed during the night with it.

All these years I used water.
On really Cold mornings the water would freeze as it hit the glass.

I would Run with pitchers of warm water to clear my windshield.
This plan is Soo much easier.

Do you do this before the ice forms, or does it work afterwards?

This was literally our Christmas present this year. Never heard of it before.

Question. What have you been doing with the now sodden cloth? Hang it in the shower to dry?

Before the frost forms.

I live out in the Middle of NoWhere;
About a quarter mile past The End of The Road.

There are no people to offend.
There are no people to take or move my 'things'.

I wear gloves, fold the towel in half and hang it over the porch rail.

Off Topic, sort of:
Spoiler:
Sound travels Far!, sometimes.

The way sound was explained to me as a child was,
"A Church on a hill can be seen."
A Church in a valley can be heard."


Then he drew pictures, waved his hands around and
I walked away with a better understanding of sound waves.

I'm taking it real slow and easy this morning.
Because, (boo-boo) I was queazy.

Anyway; I am about 2.5 miles (5 km) from the Ocean.
I can hear the breakers, through closed windows.

I live on the side of a ridge.
The ridge was formed by water, of course.

The sound travels up that water way
in many of the same ways the water moves down it.

Hum...Should this be in Random Natterings?
Oh-Ho-Humm...
As long as I am at it,
Will someone re-explain some wave function stuff to me?
Like I am five years old. Queazy people are not bright.

Spoiler:
I was in a place of business a few days ago.
Many of our places of business have 'views' out over the Ocean.

We watched a Squall move in from the Ocean.
When it 'hit' us...Whew-Hew! Rain!

The parking lot has a mild incline.
The water running off the asphalt parking lot formed 'waves'.

I pondered those 'waves'.
I could not explain them.

A woman sitting with me told me, she had noticed similar
'waves' moving down a small river, nearby.

Yes. The universe is made of vibrations.
Vibrations tend to set up waves and....

But; Y-O-Y, were there waves in that parking lot?


edit: Oh! Oh!
You will have to experiment with the key and the wipers.
To get the wipers in a position to hold the towel.

If you have a Fancy Pants car;
One that always secures the wipers in place;

Then you will need another way of holding the towel.

Evenly spaced waves, forming quite a neat pattern where the asphalt's in good condition? Yes, water does that. They're not vibration waves. Vibration waves would come from someone putting a plank into one end of a swimming pool and them rhythmically dunking it with his foot ... which is a strange sort of hobby for which I hope he uses a clean plank. The waves you're used to seeing on the ocean are wind-blown. The ones on the slope are often seen where water flows down a very smooth, steady slope. I don't know exactly what's going on there. Maybe it's surface tension working on it and maybe it's due to some irregularities in the surface, imperfections in the skin ...
Imperfections?
Microscopic.
... but water flowing like that will ripple up, sometimes rather beautifully.

I recall something similar happening with airflow over smooth aeroplane surfaces and creating drag. A glider company made their gliders so smooth that they had to add a zig-zag-edged bit of plastic to break up that effect and prevent the vortex forming. Apparently, a glider with a zig-zag step in its wing surface has less drag than a nearly-smooth or very-smooth one without the step. They were building the glider "the wrong way round," starting by lining the mould with paint, to get a smoother finish than could ever be achieved by painting a glider they'd already built.

This would suggest it's the absence of irregularities in the surface that causes the ripples in the water, but liquid water isn't gaseous air. Hrm.

I tried to find sources to cite, but "Ripple" and "Slope" are both names of much-photographed places, "glider" is an item of furniture, "zigzag" isn't a useful search term for eliminating furniture and when I looked for "zigzag aircraft design" I got distracted by this:

Image

I'd think the waves would move downhill over the water. The water nearest the concrete or asphalt has the most resistance. Water flows fastest in the middle of a (straight) river and slowest near the bottom and the banks. If you tried to slide a satin sheet down an incline, it might fold up and over and slide over itself if that was easier than staying flat. That could happen with the water, with viscosity and the like introducing a pause where the water that's already "on top" gets going and leaves behind thinner water, like drips falling from a tap one by one.

There is a place near here where I may be able to get video of water doing this "steady ripples" thing. I shall attempt to do so at the weekend, if the weather is suitable for it.
I don't know and have no opinion.

Unfortunately there is no real answer over there, just some hunches.
Most of the time when I see runoff ripples, they're mostly caused by wind (gusts) and are apparently called capillary waves.
If the ripples also occur with regular spacing in the absence of wind, I would go with something analogous to vortex streets. It's the only type of 'regular' turbulence/fluid dynamics effect that I know of.

here's some possibly relevant esearch.

It does not 'have to' be dry. It might work if still frozen. As long as the user can press it against the glass.

This 'trick' is to allow a quick and easy get away on cold mornings.
Oh! Dear! As I ponder this easy on/easy off Trick, I am having concerns of my own.

What if; There is a Really Hard Freeze and the towel is wet?
That stupid thing might be frozen to the windshield.

Under those conditions the garden hose would be frozen, too.
(jeeze) I'd feel terrible, if you had to call into work saying,
"I can't come in today. I can't see through the towel."

There may be a very good reason this is not a common 'fix'.
It would work where I live. We rarely get a hard freeze,

A mildly irritating frost is common.
Every five years or so we get snow.

Will someone from Cold Country try this?
Let us know how it works.

I tried it.
My towel was dry at the end of the day.
We have some nice days. Today was one.

Oh! New Subject:

Thank You!! Sableagle and Flumble!
What Interesting Reading!!

I don't feel so dumb anymore.
Apparently, very few people know the down and dirty of those waves.

I am not the first person to look at Rain Waves in perplexed wonder.

Oh! Oh!
Today was a beautiful cloudless day.
Looking out over the Ocean, we could see forever.

The water was blue and the tops white; As it should be.
Exact replicas of the waves appear in mist above the waves.

I wonder; Will the Why? of That appear in the reading you left for me?
Did I ever tell you how Great the reading has been? Thank you.

Spoiler:
Abstract
Rain waves are well-organized, geometrically more-or-less perfect asymmetrical waves which are commonly found on smooth gently-sloping surfaces (such as sidewalks and streets) immediately after a rain. Swash-zone ripple marks are made by paired sets of hydraulic jumps on gently-sloping beaches during the arrival of medium-to-long period waves. These hydraulic jump sets are formed, and maintained, during the backwash, rather than during the swash, and therefore appear under conditions superficially similar to those responsible for rain waves: gentle slope, smooth or almost-smooth surface, and gravity flow. Yet the two are markedly different, and almost never co-exist. Rain waves form where discharge is steady and also large enough to produce above the wall layer a discontinuous sheet (moving ripples), but not large enough to close the gaps in the discontinuous sheet. The product of "water depth" and "velocity" (hv) has the smallest possible numerical value. Swash zone hydraulic jumps appear where the discharge is increasing (downslope) and also is too large for the sheet of moving water above the wall layer to break down into discontinuous strips (rain waves). The product "hv" is far above the minimum, perhaps by a factor of 5 to 10. Rain waves, as far as is known, do not deform the sand surface, and therefore do not leave recognizable marks on that surface. The paired hydraulic jumps, formed during the backwash, make (and maintain) swash zone ripple marks, bedding plane features so subtle that even specialists might fail to note them.
This stuff is well understood.
But; I'm not allowed to read it.

Slugs can survive extended refrigeration.


Got my celery out of the fridge, broke off a couple stalks, felt something slimy on my thumb, figured it was a little bit of rotting leaf (celery has been in there about a week), absentmindedly tried to rub it off with index finger.

It's sticking. It's moving.

That's also the treatment for ethylene glycol poisoning where fomepizole is not available.

Specific treatment for ethylene glycol poisoning includes Table 3. Intravenous administration of ethanol in ethylene glycol and methanol poisoning.

Code: Select all

Dose                   Level†              Milliliters (mL) of 10% ethanol‡
Loading                600 to 800 mg/kg    7.6 to 10/kg
Maintenance         
   Chronic alcoholic   154 mg/kg/hr        1.95 kg/hr
   Social drinker      110 mg/kg/hr        1.39 kg/hr
   Nondrinker           66 mg/kg/hr        0.83 kg/hr
During hemodialysis§         
   Chronic alcoholic   304 mg/kg/hr        3.95 kg/hr
   Social drinker      256 mg/kg/hr        3.29 kg/hr
   Nondrinker          216 mg/kg/hr        2.70 kg/hr


*The goal of ethanol therapy is to maintain the blood ethanol level between 100 and 150 mg/dL.

†mg/kg: milligrams per kilogram; mg/kg/hr: milligrams per kilogram per hour.

‡In 5% dextrose in distilled water (D5W) per kilogram body weight.

Today I learned that a USB3 thumb drive can interfere with wifi. :shock:

There was a RPi-like computer sitting on top of the router and I decided to plug in a thumb drive, after which the wireless connection on my laptop was all over the place —still a strong signal-to-noise ratio, but the connection speed kepting jumping to anywhere between 1 and 72mbps. And after moving the computer suddenly the connection stabilized.

The server is no longer allowed within 30cm of the router. (at least not with USB peripherals plugged in)

Goddamn are houses expensive. That realization has singlehandedly and drastically reshaped my entire view of the world. It is someone else's world, not mine, and I will be lucky if after a lifetime of soul crushingly hard work and saving I might earn the right to call some tiny part of it mine by shortly before I die, and until them I am a fucking serf merely existing anywhere at all at someone else's pleasure, and so beholden my entire life to the lord of the land that is not and may never be mine.

The flowers are a pretty pink and very delicate looking.

What is surprising is these little blooms have survived a near constant pounding of rain And gale force winds.
They look delicate; But, they are Tough little Peach Tree Blossoms. How will I pollinate them? No bees in rain.

What is surprising is these little blooms have survived a near constant pounding of rain And gale force winds.
They look delicate; But, they are Tough little Peach Tree Blossoms. How will I pollinate them? No bees in rain.



You can use a paintbrush or your finger for a low tech option. I've found that with lots of plants simply rubbing your fingers on the anthers, then on the stigmas will work. Lots of people suggest doing the same thing with a paintbrush, because your finger can damage the stigmas if you aren't careful.

Peaches are neat plants in general -- I hope you get some fruit from them!

Yes. That is a good idea.
As soon as it stops raining, I will do.

Last year, I got more than fifty little Nectarines from my little Peach Tree.
And; I learned Deer will climb steps for peaches, but not for kale. (me, too)

I think it was FreezeBlade that explained, Why!
Why; I took a Peach Seed from my mouth, planted it.
And; Now I get little bald Nectarines.

I was a good explanation.
I can't remember the details.

It is something like:
All Great Danes are Dogs.
Not All Dogs are Great Danes.

It may be Time for my yearly explanation.

Re: Addams

Stone fruits (cherries, almonds, apricots, peaches, plums, etc.) are not true to seed, much like apples and avocados, they can very wildly from the fruit they came from, depending on the cross pollination. If you want some other varieties on there, you can graft any other stone fruit onto that tree, stone fruit are pretty easy to graft (compared to citrus or avocado). The more you know!

Yep; unlike blackberries and raspberries, avocados are berries and not stone fruit.

To be exact, all members of genus Prunus (https://en.wikipedia.org/wiki/Prunus) can be grafted onto one another, but not other "stone fruit" (technically called "drupes" https://en.wikipedia.org/wiki/Drupe). Berries are a whole different ballgame :P

Bananas are berries.

A rough definition is that their seed(s) are embedded inside the fruit.

A few days ago, I learned that the peace sign is a combo of the flag semaphore signs for N and D, standing for "nuclear disarmament."

It also (supposedly*) resembles a "Nero's cross", leading a Dutch school to recall and destroy over 3,000 student planners.

*I tried to find more information about Nero's cross, but I can't find any sources that discuss it outside of it's relation to the peace symbol.

Today I learned that being flat-chested has its benefits. I mean, I've heard or read before that there are certain benefits but of course I didn't really pay much attention to it. But today, as I was shopping for new workout outfits to fill my wardrobe, I saw a busty woman struggling with her options. She needed a whole lot of support to exercise freely but there are also a whole bunch of other boxes she needed to tick. As for me, I just grab what I like, try it on and am good to go.

So yeah, basically I ACCEPTED (is a more accurate term) today that not having big breasts isn't all that bad.

From the Open University:
Phosphate is a chemical group consisting of three phosphates joined together.


Also:
For example, in an average adult human, up to 2.5 million red blood cells are destroyed every second and are normally replaced at the same rate (so that all the red blood cells you have in you now will have been entirely replaced in four months’ time).
I don't know and have no opinion.

Probably either had a link or was denied due to unusual use of English that sounds like a spambot using machine translated phrases.

That's my guess.

TIL that U.S. stop signs have been octagonal since 1922 (so that people seeing the backs of them know that opposing traffic is supposed to stop), but until 1954 stop signs were yellow, not red.
