Window – Exclamation mark removed, because with variable allocation side effect

I am trying to process properties file and replace some of the properties.
While I managed to implement it

(for /F "tokens=1* delims=)" %%A in ('type "%file%" ^| find /V /N ""') do (
  echo/%%B
  ...
)) > result.txt

as a side effect, all exclamation marks (!) were removed from the result file. Is this a bug in Windows Batch or am I missing something?

linear transformations – What is the geometric interpretation of the effect of a degenerate real oblique symmetric matrix?

As in What is the geometric effect of an obliquely symmetric matrix on any vector? Explained, any real diagonally symmetric matrix can be placed in the block diagonal shape
$$ begin {bmatrix}
begin {matrix} 0 & lambda_1 \ – lambda_1 & 0 end {matrix} & 0 & cdots & 0 \
0 & begin {matrix} 0 & lambda_2 \ – lambda_2 & 0 end {matrix} & & 0 \
vdots & & ddots & vdots \
0 & 0 & cdots & begin {matrix} 0 & lambda_r \ – lambda_r & 0 end {matrix} \
& & & begin {matrix} 0 \ & ddots \ & & 0 end {matrix}
end {bmatrix} $$

via an orthonormal similarity transformation. This shows that the geometric action of the operator is to destroy vector components in certain directions and to expand and rotate other components $ pi / 2 $ by doing $ x ^ i-x ^ {i + 1} $ Airplanes in other directions.

But I'm curious what happens in the "degenerate" case. Consider the simplest case with no significant loss of generality, in which we have a single pair of degenerate blocks. the operator $ A $ is orthonormally similar to
$$ left ( begin {matrix}
0 & lambda & 0 & 0 \
– lambda & 0 & 0 & 0 \
0 & 0 & 0 & lambda
0 & 0 & – Lambda & 0
end {matrix} right). $$

Again, we can further simplify without significant loss of generality by rescaling the operator by $ 1 / lambda $ to get that $ A $ is (except for a total constant) orthonormally similar to
$$ left ( begin {matrix}
0 & 1 & 0 & 0 \
-1 & 0 & 0 & 0 \
0 & 0 & 0 & 1 \
0 & 0 & -1 & 0
end {matrix} right). $$

Is there a simple geometric characterization of the set of such operators? $ A $ (beyond the generic situation described above)?

Roughly speaking, I'm curious about the geometric symmetry group of such an operator. For example, from my experience with diagonalizable matrices, I suspect that such a "degenerate" operator is secretly isotropic (or at least has a higher degree of geometric symmetry than the generic antisymmetric case). Is this the case or is there a unique pair of orthogonal planes in $ mathbb {R} ^ 4 $ at what turns do they occur? If it is isotropic, is there a simpler / geometrically more intuitive description of its effect that obviously demonstrates isotropy?

unity – How do I play the particle effect of a parent object without playing its child object?

In my game, when a body part of the enemy is hit by a bullet, that body part is supposed to play a particle system effect that spits out blood. Some body parts are nested (foot is a child of the lower leg and lower leg is a child of the thigh, etc.). This is inevitable, as I use bone animations. The problem is that when I play the particle effect of an object, it also reflects the particle effect of all children. Is there a solution for this?

Enter image description here

private void OnTriggerEnter2D(Collider2D other)
{
    if (other.CompareTag("Enemy"))
    {
        other.GetComponent()?.Play();
    }
}

Recording Technique – What is this effect when millions of colored points of light surround people in the dark?

The correct term for what you refer to is a "blur circle" that occurs to mark blurred markers. The blurrier a point is highlighted, the greater the blur circle to the size of the entrance pupil (which is the ultimate limiting factor).

Bokeh, derived from the Japanese word boke (ボ ボ, "haze" or "blur"), simply refers to blur … usually background, but also foreground. Boke does not specifically refer to blurred highlights that form blur circles. Blur circles are a specific aspect of photography. When made with a high quality lens that produces high quality blurs, they are usually quite appealing.

In your photo, it looks like blur circles, but with relatively little blurring. I also suspect that they are generated by very small point light sources … Christmas lights, possibly the result of firecrackers etc.

Effect – How do I get this misty / cold / bluish look in my photos?

Most of these images have two distinct characteristics: color palette and blurred lighting.
Let's tackle them separately.

I am always tempted to believe that a change has been made as simple as possible rather than as complicated as possible …

The comparison of the first set of & # 39; ravenclaw & # 39; images with the second & # 39; Cup & # 39; image was the only common feature of the color palette.

This made me think that "something else" was done to achieve the Ravenclaw effect and that "something else" was not complicated.
To quickly try to match this second image to the Ravenclaw composite in Adobe CameraRaw, I set the Highlights and White values ​​to -100 and Dehaze to -50.

That can not be coincidence, right?

From

we get very easy
Enter image description here

without further effort?

Looking similar …?

With the same three sliders, you can quickly and easily compensate for all these images with very little color difference … once your initial color palette is set.

By the way, I'm not saying that's all they did to you – I just think they were so homogenized afterwards.

Another answer mentioned that the white balance had been adjusted. I do not think so, as some of these shots have delicate pinks and flesh tones that would be decimated by shifting the white balance. I think that selective color saturation levels were used to get the initial hue.

You can even do it if there's hardly any blue at the beginning – this image comes directly from another answer from me – the bear and the bookshelf … pull the saturation into the orange, press the little blue, and then lift & forth. dehaze as described above.

The white balance will not be changed. it affects the overall tonality, but "white" is still "white" … or indeed light gray, but without color cast.

World of Darkness – Can we cancel the Vissicitude effect by cutting off the affected limb and then regenerating it?

I have a friend who knows I'm a big fan of the Tzimisce clan, and I wonder how Vissicitude works. And after I told her that it was permanent, unless you came from a better generation (or you're a Nosferatu and used Vissicitude to pick up your curse), she said that it's super strong, and present me then a situation:

Let's say I play a vampire with a high (aka bad) generation and
A tzimisce with a lower (alias stronger) use Vissicitude with me
make one of my arm unusable. Can I cut my arm where it was not affected?
Vissicitude and regenerate it from this point? Or my arm is useless forever
until I find a friendly Tzimisce to cancel the effect?

My guess as a GM would be, at least to keep the game amusing, but I have not figured out if RAW is true or not. So here I should know and answer the question of my friend:

"Can we cancel the Vissicitude effect by cutting off the affected limb and then regenerating it?"

Image stabilization – What is the reason for a wave effect on photos taken with a helicopter?

I can tell you that it is not the window. I fly a lot in helis for work and we ALWAYS work with open doors. I came across this thread because I specifically looked for the answer after seeing it on my own iphone photos of two different iPhones, series 6s plus and 8 plus. I have put forward a similar theory to Calyth that the downforce of the blade changes the composition of the air, creating a separate "lens". Here is one that I took that showed this phenomenon. Again, this is not taken through a window, as we always fly without doors. Enter image description here

Character Creation – Can an Alternate Effect Have the Reaction Additionally?

I played for a while to become a kung fu master Mutants and mastermindsand I'm almost done. I am not sure if I have properly constructed their attacks. The image I had in my head was that if he could not hit him, he could hit people on the head and make a devastating impact if he could concentrate Where he met.

That's what I thought up:

Multi Attack Damage 5 -linked- Weaken (Fighting (Fort Save)) 10 -linked- Affliction (Fort Save) 5

Switch

Reaction, multiple attack damage 5

Is that correct? If so, how does the power supply work?

Mutants and Masterminds 3e – If I have an Extended Teleport effect, can it trigger if I turn off?

That's the power I bought for my character

Triggered(1) Extended Teleport 10
Trigger: When Artifice is knocked out, he teleports away from enemies to a teleport beacon he's set up.

Teleport says this:

You can move instantly from place to place without crossing the distance in between. You can teleport yourself and
up to 50 lbs. (mass rank 0) of additional mass a distance
rank equal to your effect rank as a move action. Unwilling
passengers get a Dodge resistance check to avoid being
taken along.

Extended says:

Extended: You can take two move actions to make an extended teleport with a distance rank equal to your effect
rank +8. You are dazed and vulnerable for one round after
an extended teleport. +1 cost per rank.

Triggered this says:

You can “set” an instant duration effect with this modifier
to activate under particular circumstances, such as in response to a particular danger, after a set amount of time,
in response to a particular event, and so forth—chosen
when you apply the modifier. Once chosen, the trigger
cannot be changed.
The circumstances must be detectable by your senses.
You can acquire Senses Limited and Linked to Triggered
effects, if desired. Setting the effect requires the same action as using it normally.

Can I use the Triggered modifier to teleport when my character is disabled, and can I use the Advanced modifier with it?
