Web Development: Does the replacement of ad units in AdSense affect revenue because of the history of specific locations?

I've created a website at the help of blogger.com and I have AdSense ads on this site. Sometimes I delete Adsense Ads from the blogger template and create new Adsense ads to replace them.

Then I noticed that when I delete existing ads and create new ads, the revenue decreases. I think this is not because of the number of clicks generated by the ads but by the impressions.

Does AdSense analyze historical data for individual ads when calculating revenue from impressions? If so, how much time do they analyze? Is it like seven days, a month or something?

nt.number theory – How did Gauss find the units of the cubic body $ Q[n^{1/3}]$?

I recently read an article on jstor "Gauss and the early development of algebraic numbers", which describes the genesis of Gauss's ideas on the foundations of the algebraic theory of numbers, among other useful information, he mentions a certain ternary cubic form that Gauss studied in 1808 to try to understand the principles under higher rates of reciprocity (cubic reciprocity in this case).

The particular form is:
$$ F (x, y, z) = x ^ 3 + ny ^ 3 + n ^ 2z ^ 3 – 3nxyz $$ and Gauss attempted to find (rational) solutions to the Diophantine equation $ F (x, y, z) = $ 1. As the article explains, this particular form appears as the norm of the number $ x + vy + v ^ 2z $ (or $ v = n ^ {1/3} $) in the pure cubic field created by joining $ v $ the field of rationals. Since Gauss wanted to know where this expression was equal to 1, this investigation can be interpreted as an attempt to find the units (norm 1 numbers) in this cubic field. Gauss then recorded the units for some values ​​of n and, in some cases, presented the fundamental unit.

I have not found enough information about this Gaussian investigation. So now, to my questions:

  • What was the Gauss procedure? And how does this relate to Gauss's other investigations in the algebraic theory of numbers?

  • Does this have anything to do with the Dirichlet Unity Theorem?? I ask the question because this article says that the Gaussian investigation was "a step in the progression of Lagrange to Dirichlet, the latter having developed in 1842-1846 the general theory of algebraic units …".

Why does the use of different units but of the same physical value give a different result?

I'm trying to define a variable with the value of the thermal constant $ V_T $. The value of the thermal constant is given in Volts as follows: $ V_T = frac {k T} {q} $, or k $ is Boltzmann's constant and $ q $ is the charge on an electron.

Why do I have different results from the following two entries:

k = quantity["BoltzmannConstant"];
q = quantity["ElementaryCharge"];
T = UnitConvert[Quantity[25, "DegreesCelsius"], "Kelvin"];
Index[v, t] = UnitConvert[(k T)/q, "Volts"]

Which returns the expected value of Amount[0.0256926, "Volts"].

k = quantity["BoltzmannConstant"];
q = quantity["ElementaryCharge"];
T = quantity[25, "DegreesCelsius"];
Index[v, t] = UnitConvert[(k T)/q, "Volts"]

Which returns the unexpected value of Amount[0.590610, "Volts"].

The only difference between the two is that in the first, I convert the degrees Celsius to Kelvin; However, the inherent physical value does not change. So, when I convert to Volts, should not I get the same result with both inputs?

Algorithm for allocating units to customers according to preferences

I am looking for a simple algorithm to assign a real estate unit to the client according to their preferences, as in the following table.

Each client has priorities and we should assign a unit to each client. What is the name of this type of algorithm to cover all scenarios.

3d – Interpretation of focal length in units of pixels

I'm working on some kind of rendering engine and I have some basic questions. Suppose I have a vector in a 3D virtual world without a unit and want to project it on a 2D screen. I therefore need its position in pixels.

My experience is in computer vision, so here is how I would model the problem.

p = K * [R | t] * v

or v is my 3D vector in homogeneous coordinates. R is a 3×3 rotation matrix, t is a 3×1 translation vector, and K is a 3×3 "camera matrix". The matrix of the camera takes the following form

f 0 cx
0 f cy
0 0 1

F is the "focal distance" of the virtual camera and cx, cy is the "main point" in pixels (usually the center of the screen).

So, assuming that my camera is originally (and static), [R | t] moves the 3D vector v somewhere in front of the camera and I get some v & # 39;. Now, I want to project a 3D vector v & # 39; on the screen.

v = [x' y' z']^ T

Kv = [fx*x'+cx fy*y'+cy z']^ T

Now dividing by perspective z & # 39; I receive p.

p = [(fx*x'+cx)/z' (fy*y'+cy)/z' 1]^ T

It certainly works in the code and I get favorable results in my renderings.

But I do not understand fundamentally what it means to express a focal length in terms of pixels. In a real camera, it is the physical distance between the imaging plane and the focal point of the lens, but the analog does not exist in 3D.

In addition, I do not really see why dimensional analysis works, and why p is indeed in units of pixels.

Thank you for reading!

How many weight units does an entry use?

What is the unit cost by weight of an input?

Two things affect the weight of a broadcast, the total number of bytes and the total number of bytes minus the witness data.

Transaction weight = Base transaction size * 3 + Total transaction size, or

Size of the base transaction is the size of the serialized transaction with the cookie data stripped.

Total size of the transaction is the transaction size in serialized bytes, as described in BIP144, including master data and control data.

See BIP141

Can you group / aggregate inputs or is it a linear growth when you
to add more entries to a tx?

You can not batch entries, but you can combine them and return them to you first with a larger amount, but this requires an additional transaction. The best you can do now is probably to use a separate address to receive funds. Thus, when you spend the inputs, the cookie data reduces the weight of each entry.

group theory – Units in the group rings.

Let $ G $ to be a resolvable final order group $ n $and let $ g_1 … g_n $ to be an enumeration of its elements. Let $ a_1 … a_n $ to be a sequence of integers, such as $ sum a_i $ is relatively good for $ n $.

Consider $ mathbb {C}[G]$, the group ring of $ G $ with complex coefficients. Does the element $ sum a_i g_i $ does it have to be a unit of the group? (I believe that the element must be a unit and have a proof in the cyclic and abelian case, but hoped for a more general reference, at least in the case where $ G $ is soluble.)

1. Analysis of introduction

The first step is an introductory analysis that will allow the protection team to verify the initial risks.

2. Risk design

Hazard design involves working with vendors to perceive critical areas of functions that handle sensitive information. The model is used to map the floating facts and identify critical areas of the application infrastructure that require special attention in terms of protection.

3. Analysis of the architecture

Architecture analysis is an essential step in determining the safety hazards achievable at the beginning of the improvement work.

4. Code evaluation

During this phase, the coding of the system takes place. When the modules and phases are completed, and as soon as the unit tests are completed, unit protection tests must be performed at a given stage of the improvement process.

5. Risk Assessment

Although protection reviews have been conducted throughout the cycle, at this stage a pre-deployment hazard assessment is a step toward benchmarking.

6. Risk reduction

Risk reduction includes prioritization, assessment, and imposition of controls that the protection team identifies as critical to mitigating vulnerabilities discovered during the assessment phase. risks.

7. Criteria for evaluation

The next step is to evaluate the resulting application against the company's requirements for providing a safety dashboard.

8. Conservation

In order to maintain the robust security posture in place, it is essential to consider using periodic safety assessments of all critical functions and controls.


5th dnd – Does "all targets must be in a unit diameter X (circle)" is equivalent to "all targets must be in an X units of the other"?

Several spells – or improved versions – have a language like this (person of charm At higher levels of Player's manual):

Creatures must be within 10 yards of each other when you target them.

I believe the statement above is equivalent to "The creatures must have a diameter of 30 feet (that is, a radius of 15 feet)".

By playing with such spells and using figurines and rugs, I and others have sometimes begun to measure the distances between pairs of targets, rather than simply dropping a circular 30-foot diameter template to see if they can all integrate.

Am I understanding, and are the two sentences of my title exactly equivalent?

Note 1: I understand the difference between targeting an area of ​​effect, such as a circle or sphere, and targeting specific creatures in an area.

Note 2: Similar language appears in other editions, for example heal mass of minor wounds of Player's manual v3.5: "A creature / level two of which can not be separated by more than 30 feet."

systemd – analyzable output from systemctl (for example, list all units)

I'm not happy about the release of systemctl

I have a script that analyzes the output of

systemctl list-units -t service --full --all

The beginning of the exit looks like this:

after-local.service loaded dead inactive /etc/init.d/after.local Compatibility
● amavis.service dead inactive not found amavis.service
apparmor.service loaded active left loaded AppArmor profiles
auditd.service loaded active running Security Audit Service                                   

On a different system, the column with the dot (before amavis.service) does not exist.

Is there a machine readable output / script of systemctl?
