# HW of Fama-Macbeth
## So WTF is Fama-Macbeth reg???
- 1973年由这两个人提出，目的是检验CAPM
- 两步**截面**回归，which可以排除残差在截面上的相关性对标准误的影响
- 所以这句话是什么意思，什么的标准误，什么的的残差？？
- 在金融领域，这个回归常被用于在多因子模型中分析投资标的截面预期收益率与因子暴露的关系
- 这又是什么意思，什么叫截面预期收益率，是不考虑历史因子值，只考虑当期因子值的意思吗
- Two- pass regression estimate
## Show me formula!!
### Step1
对单个股票的时间序列做如下回归，得到个股收益率在因子上的暴露$\beta_i$ d s s s s s s s s s s s
$$
R_{it}=\alpha_i+\beta_i'f_t+\varepsilon_{it}
$$
这里的因子 $f$ 可以是随便什么东西，可以是某个特殊组合的收益率，也可以是宏观指标等。
上面这个回归有些比较显然的事实：
- 第一步回归的残差是与$i,t$有关的，说的是$i$股票回归后在$t$时刻的残差
- 然后回归出来的$\alpha_i,\beta_i$都是与时间无关的，简直可以看作是股票$i$的一个固有属性啊，太厉害了
### Step2
第二步做了如下的截面回归：
$$
R_{it}=\beta_i'\lambda_t+\alpha_{it}\\
矩阵形式：\\
R_t=\beta'\lambda_t+\alpha_t\\
R_t:N\times1,\quad
\beta:K\times N,\quad
\lambda:K\times1,\quad
\alpha_t: N\times1
\\
\hat{\lambda}=\frac{1}{T}\sum\limits_ {t=1}^T\hat{\lambda_t}\\
\hat{\alpha}_i=\hat{\lambda}=\frac{1}{T}\sum\limits_ {t=1}^T\hat{\alpha}_{it}
$$
这个回归注意下，Fama-Macbeth的这个回归是在每一个 t 都做了一次**截面**回归，也就是说每一个 t 时刻固定的情况下回归出一个 $\lambda_t$ 和 $\alpha_{it}$ ,然后在把他们取均值。
这要怎么理解呢，我的哥啊
- 先看做平均之前的估计出的estimators有啥含义吧嘻嘻^^
- 其这个回归的式子是拿 t 时刻截面上的100家公司的收益回归到他们的固有属性，which is因子暴露上
- 这里 t 时刻的$\lambda_t$表示的其实是一个斜率，什么的斜率呢？SML的斜率，怎么解释呢？其实我们知道在 t 时刻这个截面上，有很多支股票对吧，有个显然的事实是每个股票的 $\beta$ 都是不一样的，当然他们的收益也是不一样的，然后我们又假定了 $\beta$ 与收益的关系是线性的，那么这个回归出的 $\lambda_t$ 就会是个斜率，代表了在 t 时刻，收益率与 $\beta$ 的一个关系，虽然每个公司的 $\beta$ 都不一样，但是还是可以总结为有 K 种 $\beta$ ，所以相应的，会有 K 个 $\lambda_t$ 。

<h2>What is Lorem ipsum?</h2>
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum has been the industry's standard dummy text ever since the 1500s,
when an unknown printer took a galley of type and scrambled it to make a type specimen book.
It has survived not only five centuries, but also the leap into electronic typesetting,
remaining essentially unchanged. It was popularised in the 1960s with the release of
Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing
software like Aldus PageMaker including versions of Lorem Ipsum.
</p>
<h3>Why do we use it?</h3>
<p>It is a long established fact that a reader will be distracted by the readable content of a
page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less
normal distribution of letters, as opposed to using 'Content here, content here', making it
look like readable English. Many desktop publishing packages and web page editors now use
Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many
web sites still in their infancy.
</p>
<h4>What you need to know about lorem ipsum</h4>
<p>
There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration
in some form, by injected humour, or randomised words which don't look even slightly believable.
If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden
in the middle of text.

# Data Pipeline and ETL Process
## Project Overview
This project aims to establish a robust data pipeline and ETL process on Google Cloud Platform to automate the extraction, transformation, and loading of cricket ranking data from various APIs into Google BigQuery for analysis and visualization in Looker Studio.
## Architecture Diagram
## Components and Workflow
## Data Extraction
1. **Python Script**: A Python script extracts cricket rankings data from APIs and uploads it directly to Google Cloud Storage (GCS).
2. Airflow on Compute Engine: Airflow is set up on a Google Compute Engine instance to orchestrate and automate the Python script execution based on a predefined schedule.
## Data Processing and ETL
1. **Dataflow**: Utilizes a custom template to process and transform data extracted from GCS, parsing and inserting it into BigQuery.
2. Cloud Functions: An intermediate Cloud Function triggers the Dataflow job automatically whenever new data files are uploaded to GCS.
## Data Storage
1. **BigQuery**: Serves as the centralized data warehouse where transformed data is stored in date-partitioned tables for optimized query performance and cost-efficiency.
## Data Visualization
1. **Looker Studio**: Used for creating interactive dashboards and reports to visualize and analyze processed data.
## DevOps Integration
1. CI/CD Pipeline: Includes integration with Cloud Source Repositories and GitLab for version control, along with Cloud Build for automated builds and deployments.
2. Terraform: Infrastructure as Code (IaC) is used to define and provision all required cloud resources in a repeatable and consistent manner.
## Goals and Functionalities
1. **Automated Data Ingestion**: Scheduled extractions from APIs to GCS.
2. **Real-time Data Processing**: Immediate processing of new data files through Cloud Functions and Dataflow, ensuring data is timely and relevant.
3. **Scalable Storage Solutions**: Use of BigQuery for scalable and efficient data storage.
4. **Seamless DevOps Practices**: Implementation of a CI/CD pipeline to streamline updates and deployments of the pipeline components.
5. **Governance and Best Practices**: Adoption of best practices in cloud resource management and data governance.

% - TriEdg(Nbtri,3) : Pour chaque triangle, TriEdg(l,i) est le numero de l'arete opposee au sommet NumTri(l,i)
% (3 numeros des aretes - matrice entiere Nbtri x 3)
% - EdgTri(NbEdg,2) : Pour chaque arete, EdgTri(a,:) donne les numeros des 2 triangles de chaque arete
% EdgTri(a,2) = 0 si a est sur la frontiere
% - Lga2(NbEdg,1) : longueurs des aretes au carre
% - EdgNorm(NbEdg,2) : vecteurs face-normale, orientes tri1->tri2
% - Aires(Nbtri,1) : aires des triangles

description: Learn about common issues that you may encounter when using GitKraken Client.

category: gitkraken-client

***
### General Troubleshooting for GitKraken Client 9.4.0+
In 9.4.0, GitKraken introduced the experimental feature for the [Git Executable](/gitkraken-client/experimental-features/#git-executable). As this is currently an experimental feature that our team is continuing to improve on, you can try adjusting your use of the Git Executable.
Under `Preferences > Experimental`, first try adjusting the `Git Executable` version used. If you are using the “Bundled with GitKraken” version (comes pre-installed with GitKraken) try changing this to your own version of Git. If you do not have this installed, it can be downloaded [here](https://git-scm.com/download).
The reason this may help is because the Bundled version is a minimal install of Git, which does not include all features (specifically bash programs that may be used in Git Hooks).
<img src="/wp-content/uploads/gkc-git-executable-version.png" class="img-responsive center img-bordered">
If using your own version does not resolve the issue, try unchecking `Use Git Executable`.
<img src="/wp-content/uploads/gkc-use-git-executable.png" class="img-responsive center img-bordered">
If this does resolve your issue, it is very important to note that GitKraken Client is transitioning all actions to the Git Executable (from LibGit2/nodegit) and the Git Executable will become the exclusive way GitKraken Client performs Git operations in a future release.
As such, it is crucial for our team to be made aware of any issues related to using the Git Executable so we can look into and address them. Please reach out to our [support team](https://help.gitkraken.com/gitkraken-client/contact-support/) if you experience any issues with using this Experimental feature.
For more information on what this feature is and why it is being implimented, you can check out this [blog post](https://www.gitkraken.com/blog/gitkraken-client-migrating-from-libgit2-to-git-executable).

## Integration - 1000 Error (1002, 1003, 1005, 1007)
When attempting to connect to one of our integrations, you may see `Error 1002`, `Error 1003`, `Error 1005` or `Error 1007`.
<img src="/wp-content/uploads/error-1002.png" srcset="/wp-content/uploads/error-1002@2x.png 2x" class="img-responsive center img-bordered">
### Solution:
These are general authentication errors. First, verify you used the correct credentials then try one of the following potential solutions:
- If your credentials are correct, you can try signing out of the service in your default browser first, and then attempting the authentication from GitKraken Client again.
- Clear your browser cache, sign out of the git hosting service, then restart GitKraken Client and try again.
- If that is not working you can also try changing your operating system default browser to be a different browser. Once this is changed you can restart GitKraken Client and attempt to authenticate again.
If that still does not work, please contact our [support team](https://www.gitkraken.com/contact) and we can troubleshoot further.
***
## Error when pushing a branch
When attempting to push a branch, you may see the following `Push Failed: Cannot read property 'fullName' of undefined` error:
<img src="/wp-content/uploads/push-error.png" class="img-responsive center img-bordered">
### Solution:
This usually indicates that there is a casing difference between the local branch and the upstream remote branch. You can rename the local branch to match the casing of the upstream remote branch, which will allow you to push the changes.
<div class='callout callout--warning'>
<p>Note: You may need an intermediate name change to get the branch named correctly. For example: Test-branch > temp-name > test-branch</p>
</div>
***
## Some branches or files not appearing - Capitalization issue
This most often occurs when having multiple remote banches nested together, but the capitalization differs. For example: `Feature/foo` and `feature/foo` may either be detected as the same branch OR a different branch depending on how your operating sytem treats capitalization. Most often this appears on Windows machines.
Symptoms:
- Branches not appearing in GitKraken - only one of the branches will be detected when they share a name.
- This can also apply to files. If two files share the same name with only different capitalization one may appear deleted, moved, or not at all.
- This can also manifest as the file being staged but not showing as staged when running a `git status`.
To avoid these capitalization issues, we recommend giving each branch, file, and remote a unique name.
***
## Cannot log in - Cannot read property 'email' of null
When trying to log in, you may see the following error: `Cannot read property 'email' of null`. This is commonly related to a network issue such as a proxy, firewall, or security application. The most common occurrence is something like Zscaler.
### Solution:
If you have any of the above in place try the following:
- Sign in with GitHub authentication
- Approve the GitKraken application
- Continue as free with 0 days
- Click on free icon in bottom right, this brings up a web page inside GitKraken Client which authenticates against Zscaler
- Restart GitKraken Client and authenticate normally
This should allow you to log in without issue.
***
## Windows taskbar icon is not showing the GitKraken logo
Some Windows users are seeing the taskbar icon show incorrectly for GitKraken. This is due to the start menu shortcut moving from ``C:\\Users\\USER\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Axosoft, LLC`` to ``C:\\Users\\USER\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\GitKraken``.
### Solution:
You can delete the old folder ``C:\\Users\\USER\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Axosoft, LLC``, start GitKraken from the start menu, and then pin it to the taskbar again to resolve this.
## Why can't I see my GitHub remotes or repositories in the drop down menu? Why am I getting an error about GitHub organization permissions?
In order to work with with a repository owned by a GitHub organization with the GitHub integrtion connected, you need an organization to first allow access.
<img src="/wp-content/uploads/error.png" class="img-bordered img-responsive center">
* First check to see if access is allowed to GitKraken from your profile's [GitHub Applications](https://github.com/settings/connections/applications/a7557949433b7d282a76)
* If access has been allowed, then the organization will need to allow [Organization Approval](https://help.github.com/articles/requesting-organization-approval-for-your-authorized-applications/)
* If you are attempting to use GitKraken with a repository owned by a different individual, consider forking their repository to use GitKraken for your changes. Otherwise this other individual will need to first [install GitKraken](/gitkraken-client/how-to-install/) and connect it to GitHub to authorize GitKraken.
* For details about third-party application restrictions view [Third-party apps list](https://help.github.com/articles/about-third-party-application-restrictions/)

* Creates a debounced function that delays invoking `func` until after `wait`
* milliseconds have elapsed since the last time the debounced function was
* invoked. The debounced function comes with a `cancel` method to cancel
* delayed `func` invocations and a `flush` method to immediately invoke them.
* Provide `options` to indicate whether `func` should be invoked on the
* leading and/or trailing edge of the `wait` timeout. The `func` is invoked
* with the last arguments provided to the debounced function. Subsequent
* calls to the debounced function return the result of the last `func`
* invocation.
*
* **Note:** If `leading` and `trailing` options are `true`, `func` is
* invoked on the trailing edge of the timeout only if the debounced function
* is invoked more than once during the `wait` timeout.
*
* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
* until to the next tick, similar to `setTimeout` with a timeout of `0`.
*

_Valor por Referencia:
______________________
_en las variables, su valor es dinámico y puede cambiar en el tiempo
es decir, que su valor lo podremos alterar en el tiempo posteriormente haciendo referencia a la respectiva veriale y re asignándole un nuevo valor
_más en los objeto esto no es así, cuando una variable hace referencia a un objeto, ej;
var proof1 = {
nombre: "Juán";
}
var proof2 = proof1;
console.log(proof1, proof2);
_en éste ejemplo creamos el objeto proof, con una propiedad de "nombre", y asu vez creamos el objeto "proof2", con el valor del objeto "proof1"
_más que pasará si accedemos a la propiedad "nombre", del objeto "proof", y cambiamos su valor, ej;
_proof1.nombre = "Pedro";
_en éste caso cuando llamemos a la variable "proof2", ahora ésta también, tendrá el mismo valor de propiedad de "Pedro", que el del objeto "proof1"
_de ésta manera, podremos ver que cuando un objecto hace referencia ha otro objeto, éstos compartirán todas sus propiedades internas y características

Problem Description
Construct a class Rectangle that represents a rectangle.
The class should support the following functionalities:-
perimeter() -> returns the perimeter of the rectangle
area() -> returns the area of the rectangle
Input format:
First argument A is an integer representing the number of testcases.
For each case, x (length) and y (breadth) are taken as input in new line.
Output format:
The perimeter and area of the constructed rectangle are printed.
class Rectangle {
// Define properties here
int length;
int breadth;
// Define constructor here
Rectangle(int x,int y){
length=x;
breadth=y;
}
int perimeter(){
// Complete the function
int a = (2*(length+breadth));
return a;
}
int area(){
// Complete the function
int b = length*breadth;
return b;
}
}
/*
Rectangle a = new Rectangle(2, 3) // Length = 2, Breadth = 3
a.perimeter() // Should give 10
a.area() // Should give 6

<p>I often take satellite navigation systems such as GPS for granted, and it got me thinking about how dependent we are on that technology, and how on earth people managed in the past. This article documents my findings.</p>
<p>It covers the concept of latitude and longitude, and how navigation was performed on ships using star or sun location, and measuring time. </p>
<p>By the 20th century, during World War 2, techniques were developed that relied on clusters or 'chains' of ground station radio transmitters broadcasting signals that could be received on planes and ships. Each transmission within a chain had a certain time relationship with each other. The article discusses how that information could trace out invisible curved (hyperbolic-shaped) lanes over land or sea, and how those curves could form a sort of grid.</p>
<p>There is also a brief look at how GPS works.</p>
<h1>Longitude and Time-keeping</h1>
<p>In the introduction of a book called <a href="https://www.amazon.co.uk/Longitude-Genius-Greatest-Scientific-Problem/dp/080271529X">Longitude</a>, Neil Armstrong mentions how <a href="https://en.wikipedia.org/wiki/Pope_Alexander_IV">Pope Alexander IV</a> drew a vertical line from North to South, and assigned all lands to the two top maritime powers of Europe: all lands to the west to Spain, and all to the right to Portugal. The problem was, no-one knew for sure where the line fell, so it was hard to argue who owned what!</p>
<p>The problem of identifying precise longitude was of high importance, because sailors would routinely perish, because of the difficulty of determining where land was.</p>
<p><img title="Latitude and Longitude diagram" width="100%" align="left" src="assets\diag-lat-lon-explained.jpg"></p>
<p><strong>Latitude</strong> (angle indicating how far up or down the globe) was not too difficult to figure out, because it could be determined in several ways; for instance you could search for particular stars (for instance the North Star, and measuring the angle of it from the horizon). A quick daytime method would be to measure the angle of the sun from your visible horizon, which is known as the sun's angle of elevation, and subtract it from 90. Then, a correction is needed because the earth tilts up to plus or minus 23.4 degrees over the course of the year; it's seasonal (about +23.4 degrees in mid-June, and -23.4 degrees in mid-December, and is close to zero mid-March and mid-September), is easy to calculate, and is called the sun's angle of declination. You'd need to subtract the magnitude of that angle of declination, to get an accurate result.</p>
<p><img title="Measuring Latitude" width="100%" align="left" src="assets\diag-latitude.jpg"></p>
<p>However, <strong>longitude</strong> starts at an arbitrary man-made position (it happens to be in Greenwich, London). There are many stories of ships traveling the wrong distance east or west around the globe, and poor longitude estimates resulted in either crashing into rocks, or overshooting or undershooting land, and, with depleting food, and risk of scurvy, the captain would decide to turn around, and upon traveling for days or weeks, only to then realize that the first direction must have been correct. Just on one voyage, two thousand sailors on four warships died for want of better navigation, and eventually, the UK government issued a reward (worth millions in today's money) for a solution. It went unclaimed for more than half a century.</p>
<p>Some people believed the solution lay with correct timing, however, clocks were inaccurate in the 1700's!</p>
<p>The reason time is important, is that, (there are several ways, but this is the easiest to understand) by simply looking at the position of the sun (which moves across the sky at 15 degrees per hour), and knowing the time at the Greenwich Meridian, you can determine your longitude. For example, if the sun is directly above you, and the time at Greenwich is 1 pm, then you know that your longitude must be 15 degrees west of Greenwich.</p>
<p>There were some crackpot suggestions for the time problem, one of them being 'the wounded dog' method. There was a theory that a particular medicine had mystical powers of 'healing at a distance' if the original bandage was soaked in it. The logic went that if a dog were deliberately wounded and then placed on a ship, then someone on land could daily soak the bandage at noon, and the distant wounded dog would let out a yelp at that precise time since the medicine would sting in the wound. You'd just need to deliberately prevent the wound from fully healing, for months while out to voyage.</p>
<p>The person who actually solved the problem without mystic medicine, <a href="https://en.wikipedia.org/wiki/John_Harrison">John Harrison</a>, was treated badly by his government, and, for a lifetime's work, received just a small reward with only three years of life left to enjoy it. John Harrison's solution was an ultra-accurate timepiece (so accurate, it easily competes with modern quartz watches some 250 years later!) that could withstand operation on ships.</p>
<h1>Hyperbolic Radio Navigation</h1>
<p>Fast-forward to the period approaching World War 2, and now there were requirements for accurate airborne navigation. Various radio-based ideas were considered, and it was soon very obvious that relying simply on signal strength was not very feasible because it was hard to accurately measure signal strength at a distance because it dropped off so quickly, and therefore the inaccuracies would be significant.</p>
<p>It was felt by some that pulse-based (RADAR was a secret at that time) or phase-based systems might hold more promise.</p>
<p><img title="Hyperbola Lines" width="100%" align="left" src="assets\burst-phase-systems.jpg"></p>
<p>This opened up a whole range of possibilities, collectively known as hyperbolic navigation systems. If you have two transmitters transmitting in phase, or transmitting pulses simultaneously, then if a receiver is exactly halfway between the two transmitters, then the signals arrive in phase (or pulses arrive simultaneously). If, however, the receiver is at a different location, then there will be a phase or delay difference. The difference remains the same if the receiver is at any location which traces a hyperbola. The diagram below shows why.</p>
<p>The concentric circles emanating from one transmitter site indicate the positions where signals arrive at fixed times. If you try to intersect those circles with those from the other transmitter location, such that the difference between the pairs of ranges always remains a fixed distance, then hyperbolae are traced out. All the hyperbolae in the diagram below, have the same fixed difference of phase or pulse, the colors are just to identify separate lines or 'lanes', but if the receiver is on any of these lines, the phase difference is the same. For any given delay or phase difference, it is possible to plot a set of hyperbolae.</p>
<p><img title="Hyperbola Lines" width="100%" align="left" src="assets\hyperbolae-lines.jpg"></p>
<p>What the above means is that if you have a way of measuring the phase difference or pulse arrival delay between the two transmitters, you can place yourself on a set of hyperbolae. You won't know which of the hyperbola lines you are on, however.</p>
<p>Various things can be done to try to identify the particular hyperbola out of the set. One method is for the two transmitters to sweep through phase relative to each other. That results in the hyperbola lines bending as the phase changes so that the receiver sees a time-varying signal strength, an increase in received signal when they are on a hyperbola, and a decrease when they are in between two lines. Then, timing can help identify which hyperbola you're on. Another method is to switch to a lower frequency, so that there are fewer hyperbola lines temporarily, so that the receiver can coarsely resolve, before switching to a higher frequency.</p>
<h1>Pulses: Gee System (QH)</h1>
<p>One system developed in the UK, later called the Gee system (known as 'QH' during WW2), relied on pulses. A master transmitter would synchronize three slave transmitters, all transmitting a pulse at the same frequency after a fixed pause from the master transmission. Together, these four transmitters are known as a <strong>chain</strong>.</p>
<p><img title = "Gee diagram" width="100%" align="left" src="assets\gee-diagram2.jpg"></p>
<p>At the receiver end, the pulses were observed on a little display (known as an oscilloscope) that charted the pulse blips over time. The circuitry would direct the pulses onto two visual graphical traces. The master transmitter pulse was observed on both traces. The next received pulse would be sent to the top trace. The pulse after that was sent to the second trace. The final pulse was sent to both traces, but it happened to be a double pulse, so it could be distinguished. The operator would measure the distance between the pulses, and the intersecting hyperbolae would provide a position fix.</p>
<p>The photo here shows a Gee receiver and display unit.</p>
<p><img title = "Gee receiver and display" width="100%" align="left" src="assets\gee-photo.jpg"></p>

<p>There is some excellent detail (including beautiful photographs) at <a href="https://www.radiomuseum.co.uk/rf25.html">radiomuseum.co.uk</a>.</p>
<p>Since there was no trigger circuitry, the operator manually fine-tuned until the pulses sat in the correct position on the display. Best-case accuracy was about 150 meters, but at distances of several hundred miles, the error could easily be several miles.</p>
<p>Gee was used during WW2 for navigation around the UK.</p>
<h1>Phase: Decca Navigation (QM)</h1>
<p>For Operation Overlord (Battle of Normandy), a different navigation system was used, called QM (later called the Decca Navigational System). The idea was invented by William O'Brien and Harvey Schwarz in the USA but gained significant interest in the UK and was trialed in 1941 on the Welsh coast. The system relied on phase difference, rather than measuring the time between pulses. The way it worked was that a master site and a number of slaves (two or three), together known as a chain, all transmitted signals at different frequencies, but all locked to a base frequency. The receiver would multiply pairs of received signals to a common frequency and then work out the phase difference.</p>
<p>In 1943, the base frequency <strong>f</strong> was 14 kHz, and the master and two slaves transmitted at <strong>6f</strong>, <strong>8f</strong> and <strong>9f</strong> respectively (i.e. 84, 112 and 126 kHz).</p>
<p>At the receiving end, the master and first slave received signals would be separately multiplied by 4 and 3 respectively, i.e. 84 x 4 and 112 x 3, which would result in two signals both of frequency 24f (336 kHz), but with different phase, depending on location with respect to the master and the first slave.</p>
<p>Similarly, the master and second slave signals would be separately multiplied by 3 and 2, resulting in two signals of frequency 18f (252 kHz), again with a phase relationship. (Later, a third slave was added, at a frequency of <strong>5f</strong>).</p>
<p>Just as shown in the earlier diagram, hyperbola lines could be drawn at any phase relationship, for instance when the signals are in phase, at zero degrees.</p>
<p>The lines were used as '<strong>lanes</strong>' during Operation Overlord, creating invisible paths through the English Channel towards Normandy. Minesweepers followed those paths, allowing ships and landing craft to follow.</p>
<p><img title="Decca test (1941) and deployment (1944)" width="100%" align="left" src="assets\nav-map-oo.jpg"></p>
<p>The receiver didn't use an oscilloscope but instead used a center-zero meter that would display the phase shift. The lanes were separated by several hundred meters. A tiny movement (a few feet) off one of the lanes would cause a phase shift from zero, which would move the meter needle significantly. By seeing the number of deflections, the lines could be easily counted. After WW2, further improvements to the system were made, so that lane counting became unnecessary. By the time the system was fully mature, the transmitter sites were transmitting signals at different frequencies, over a 20-second period, repeatedly, and the sequence was quite complex. A very good collection of information about the Decca system can be found at <a href="http://www.jproc.ca/hyperbolic/decca.html">Jerry Proc's website</a>.</p>
<p>By the 1980's or so, there were about 50 chains deployed. The diagram below shows the European chains; 25 were deployed there. The circled values are unique chain numbers. The slave transmitters within each chain had color-code identifiers (red, green, purple).</p>
<p><img title="Decca European chains" width="100%" align="left" src="assets\european-chains.jpg"></p>

<p>The Decca system was deployed in many regions, and was used commercially until about the year 2000. The receivers were made by Racal Decca, but eventually other manufacturers, particularly Philips, built them too. This model is made by Philips, despite the Racal logo.</p>

<p>If you're curious what's inside, the photo below shows all the interesting bits in the lower half of the case (the other half just houses the LCD digit displays and keypad).</p>
<p><img title="Decca Yacht Navigator internals, annotated" width="100%" align="left" src="assets\yn-parts-annotated.jpg"></p>
<p>There appears to be a frequency synthesizer, two simultaneous RF receivers (so that the phase between pairs of signals can be measured), and everything is co-ordinated with an 8085-based microprocessor. </p>
<h1>Summary</h1>
<p>It's easy to take satellite-based navigation systems for granted these days, but there was a time when thousands of lives would frequently be lost due to the difficulty of determining longitude. Although that was solved in the 18th century, there were new demands during WW2.</p>
<p>Prior to GPS deployment, hyperbolic navigation systems were the state-of-the-art, a couple of them being QH and QM, or Gee and Decca, respectively. The Decca system relied on phase measurement to place the receiver on hyperbolic lines or lanes and, with multiple transmitters, onto a grid of lanes. After WW2, the system was adapted for commercial use and ran successfully until the year 2000. An example of a Decca navigation system receiver was examined briefly.</p>
<p>There were many other hyperbolic or hyperbolic-like navigation systems that are not covered here. Some systems were incrementally improved upon, and others were independently developed. </p>
<p>Thanks for reading.</p>
<h2>Further Reading: Quick Look at Satellite-Based Navigation: How Does it Work?</h2>
<p>Now that pre-GPS techniques have been discussed, you may be interested in how GPS and other Global Navigation Satellite Systems (GNSS) function.</p>
<p>There are well over a hundred satellites in orbit, which transmit signals containing timing information and satellite position. The timing information comes from an ultra-precise clock inside each satellite. The satellite position can be pictured by imagining a sphere surrounding the planet. The satellite position can be defined using two angles: the angle from one of the poles, and the angle around the sphere (a bit like longitude), which meet up at the satellite location on that sphere.</p>
<p>The timing information, and the satellite position information, are transmitted at a frequency of about 1.5 GHz, and, due to the distance of the satellite orbit, it takes about 10 msec to arrive on Earth.</p>
<p> In the case of GPS, there are six orbital paths, about 20,000 km overhead, each with multiple satellites spaced out.</p>
<p><img title = "GPS orbits" width="100%" align="left" src="assets\gps-orbits.jpg"></p>
<p>The received signal is very weak and would be impossible to pull out of the noise, so it is sent relatively slowly (50 bits per second), with each bit of data being encoded with a special (much faster) binary pattern before it's transmitted. The GPS receiver tries to match up the pattern. When it does that, then, mathematically, the signal can be recovered from the noise; the pattern is known as a pseudo-random sequence (although it contains the word 'random', it's not random in the normal sense; it looks random to a casual viewer, but in reality it has a pattern that can be exactly replicated by the receiver), and the matching effect is known as autocorrelation. Together, it is known as Spread Spectrum communication. The signal directed toward Earth is invisible by the time it arrives (since it's below the noise floor!) until autocorrelation is achieved by the receiving system.</p>
<p>Another neat trick is that many satellites can transmit simultaneously, each with a different pseudo-random sequence, and the receiver can, in parallel, perform multiple matching operations, to achieve autocorrelation for each signal.</p>
<p>The receiver is designed to have the ability to time things too, but not to the same accuracy as the satellites! The receiver will locally timestamp the arrival time of each message, and then compare that local timestamp with the time encoded in the satellite signals. Once there are signals from at least four satellites (the more the better!), then there is enough information to use simultaneous equations, to solve for the location of the receiver.</p>
<p>Today, there are more global navigation systems than just GPS out there; there is also Galileo (European), BeiDou (Chinese) and GLONASS (Russian), all operating in a similar way. There are also more geographically-specific navigation systems too. A GNSS receiver (colloquially known as a GPS receiver) can receive information from several of the navigation systems, and therefore provide more accurate location information, by selecting based on received signal quality.</p>
<p>In order to make use of GNSS, nowadays a single chip can be used. The chip will typically receive the RF signals, shift them to a much lower frequency, then perform the correlation operation, and then pre-programmed software inside the chip will compute the receiver location. The pre-programmed software has a model of the Earth, to try to reduce errors in altitude (height) measurement, say, above sea level. </p>
<p>The altitude is interesting to briefly consider; the earth isn't spherical, it bulges a little, i.e. it is slightly ellipsoidal, plus, on top of that, sea level depends on gravity, and gravity isn't constant across the earth. Where the earth is denser, it attracts more water, and the mean sea level rises there. There is an internal table of heights inside the chip, and the reported altitude takes that into account, to try to provide an altitude value that is referenced off that internal table of mean sea levels at the reported location. It's known as an orthometric height. </p>

Technical Indicators documentation:
### Volume Based Indicators:
1. **volume_adi (Accumulation/Distribution Index)**
- **Calculation:** The ADI is computed by calculating the Money Flow Multiplier, which is then multiplied by the period's volume. This product is then added to the previous period's ADI value.
- Money Flow Multiplier = ((Close - Low) - (High - Close)) / (High - Low)
- ADI = Previous ADI + (Money Flow Multiplier * Volume)
2. **volume_obv (On-Balance Volume)**
- **Calculation:** OBV is a cumulative total of volume. Volume is added to the indicator if closing price moves up and subtracted if closing price moves down.
- If today's close > yesterday's close, OBV = previous OBV + today's volume.
- If today's close < yesterday's close, OBV = previous OBV - today's volume.
3. **volume_cmf (Chaikin Money Flow)**
- **Calculation:** CMF combines price and volume to measure the buying and selling pressure over a set period. It is the sum of Accumulation/Distribution for 20 periods divided by the sum of volume for 20 periods.
- CMF = ∑[(Close - Low) - (High - Close)] / (High - Low) * Volume / ∑ Volume
4. **volume_fi (Force Index)**
- **Calculation:** The Force Index uses price and volume to measure the power behind a price move. The shorter the period, the more volatile the indicator.
- FI = Volume * (Current Close - Previous Close)
5. **volume_em (Ease of Movement)**
- **Calculation:** EoM indicates how easily prices move. A large positive value indicates the price moved up on low volume.
- EoM = [(High + Low)/2 - (Previous High + Previous Low)/2] / (Volume / 10^6 / (High - Low))
6. **volume_sma_em (Simple Moving Average of Ease of Movement)**
- **Calculation:** This is simply the SMA of the EoM values over a specified period, often 14 days.
- SMA of EoM = Sum of EoM over N periods / N
7. **volume_vpt (Volume-Price Trend)**
- **Calculation:** VPT is a cumulative volume-based indicator used to show the direction of the trend.
- VPT = Previous VPT + (Volume * (Today’s Close - Previous Close) / Previous Close)
8. **volume_vwap (Volume Weighted Average Price)**
- **Calculation:** VWAP gives the average price a security has traded at throughout the day, based on volume and price. It is often used as a trading benchmark.
- VWAP = ∑ (Typical Price * Volume) / ∑ Volume
- Where Typical Price = (High + Low + Close) / 3
9. **volume_mfi (Money Flow Index)**
- **Calculation:** MFI uses both price and volume to measure buying and selling pressure. Often called the volume-weighted RSI.
- Raw Money Flow = Typical Price * Volume
- Money Ratio = Positive Money Flow / Negative Money Flow
- MFI = 100 - (100 / (1 + Money Ratio))
10. **volume_nvi (Negative Volume Index)**
- **Calculation:** NVI focuses on days where the volume decreases from the previous day. If volume decreases, NVI is adjusted by the percentage change in price.
- If today's volume < yesterday's volume, NVI = yesterday's NVI + (today's close - yesterday's close) / yesterday's close * yesterday's NVI.
- If today's volume ≥ yesterday's volume, NVI is unchanged.
### Momentum Indicators:
1. **momentum_rsi (Relative Strength Index)**
- **Calculation:** RSI measures the speed and change of price movements. It is calculated using average gains and losses over a specified period, typically 14 days.
- RSI = 100 - (100 / (1 + (Average Gain / Average Loss)))
2. **momentum_stoch_rsi (Stochastic RSI)**
- **Calculation:** The Stoch RSI applies the Stochastic formula to RSI values, instead of price values, to measure RSI's momentum.
- Stoch RSI = (RSI - Lowest Low RSI) / (Highest High RSI - Lowest Low RSI)
3. **momentum_stoch_rsi_k (Stochastic RSI K)**
- **Calculation:** Represents the current value of the Stochastic RSI. It's essentially the same as the Stoch RSI value and can sometimes refer to a smoothed version using a moving average.
4. **momentum_stoch_rsi_d (Stochastic RSI D)**
- **Calculation:** The D line is the simple moving average of the Stochastic RSI K line. It's used to smooth out the K line for better signal interpretation.
- Stoch RSI D = 3-day SMA of Stoch RSI K
5. **momentum_tsi (True Strength Index)**
- **Calculation:** TSI is a momentum oscillator that blends the price momentum with its moving average. It is calculated by taking a double smoothed moving average of the price momentum.
- TSI = (Double Smoothed Price Change / Double Smoothed Absolute Price Change) * 100
6. **momentum_uo (Ultimate Oscillator)**
- **Calculation:** The UO combines short, medium, and long-term market trends in one indicator. It uses three different time frames and weights them into a final oscillating value.
- UO = [(4 x SMA1) + (2 x SMA2) + SMA3] / (4 + 2 + 1)
- Where SMA1, SMA2, and SMA3 are the average ratios of buying pressure to true range over their respective periods.

- %R = [(Highest High - Close) / (Highest High - Lowest Low)] * -100
10. **momentum_ao (Awesome Oscillator)**
- **Calculation:** AO is a 34-period simple moving average, subtracted from a 5-period simple moving average. These moving averages are based on the midpoint of the bars (not the closing prices).
- AO = SMA(Midpoint, 5 periods) - SMA(Midpoint, 34 periods)
- Where Midpoint = (High + Low) / 2
11. **momentum_roc (Rate of Change)**
- **Calculation:** The ROC measures the percentage change between the current price and the price a certain number of periods ago.
- ROC = [(Current Close - Close N periods ago) / Close N periods ago] * 100
12. **momentum_ppo (Percentage Price Oscillator)**
- **Calculation:** The PPO calculates the percentage difference between two exponential moving averages (EMAs), typically the 26-period EMA and the 12-period EMA.
- PPO = [(12-period EMA - 26-period EMA) / 26-period EMA] * 100
13. **momentum_ppo_signal (Percentage Price Oscillator Signal Line)**
- **Calculation:** The PPO signal line is usually a 9-period EMA of the PPO itself. It is used to generate trading signals.
- PPO Signal = 9-period EMA of PPO
14. **momentum_ppo_hist (Percentage Price Oscillator Histogram)**
- **Calculation:** The PPO histogram represents the difference between the PPO and its signal line. It's used to identify bullish or bearish momentum.
- PPO Histogram = PPO - PPO Signal
15. **momentum_pvo (Percentage Volume Oscillator)**
- **Calculation:** Similar to the PPO but for volume. The PVO measures the difference between two volume EMAs as a percentage of the longer EMA, typically the 26-period EMA and the 12-period EMA.
- PVO = [(12-period Volume EMA - 26-period Volume EMA) / 26-period Volume EMA] * 100
16. **momentum_pvo_signal (Percentage Volume Oscillator Signal Line)**
- **Calculation:** The PVO signal line is a 9-period EMA of the PVO, used to generate trading signals based on volume.
- PVO Signal = 9-period EMA of PVO
17. **momentum_pvo_hist (Percentage Volume Oscillator Histogram)**
- **Calculation:** The PVO histogram is the difference between the PVO and its signal line, indicating changes in volume momentum.
- PVO Histogram = PVO - PVO Signal
18. **momentum_kama (Kaufman's Adaptive Moving Average)**
- **Calculation:** KAMA adjusts its sensitivity based on market volatility. It starts with an Efficiency Ratio (ER) and then applies smoothing constants to an EMA based on the ER, to calculate the moving average.
- ER = Absolute value of [(Current Close - Close N periods ago) / Sum of N period Absolute Price Changes]
- KAMA = Previous KAMA + SC * (Current Price - Previous KAMA)
- Where SC (Smoothing Constant) is calculated based on the ER and specified fast/slow EMA constants.

34. **trend_adx_neg (-DI, Negative Directional Indicator)**
- **Calculation:** -DI measures the downward trend strength. It's similar to +DI but uses -DM (negative directional movement).
- -DI = 14-period EMA of -DM / ATR.
35. **trend_cci (Commodity Channel Index)**
- **Calculation:** The CCI compares the current price to the average price over a specific time period. It's designed to identify cyclical trends.
- CCI = (Typical Price - 20-period SMA of TP) / (0.015 * Mean Deviation),
- where TP (Typical Price) = (High + Low + Close) / 3.
36. **trend_visual_ichimoku_a**

- Aroon Down = [(25 - Periods Since 25-period Low) / 25] * 100
40. **trend_aroon_ind (Aroon Indicator)**
- **Calculation:** The Aroon Indicator is often represented by the Aroon Up and Aroon Down lines. However, some calculations might represent it as the difference between Aroon Up and Aroon Down to provide a consolidated view of the trend.
- Aroon Indicator = Aroon Up - Aroon Down
#### Parabolic SAR Components:
41. **trend_psar_up**
- **Calculation:** This value is calculated during a downtrend when the trend reverses to uptrend. The Parabolic SAR for the next period is calculated using the previous period's SAR, the extreme point (EP, which is the highest high during the current uptrend), and the acceleration factor (AF). For an uptrend, the SAR is calculated as:
- `PSAR = Previous PSAR + AF * (EP - Previous PSAR)`
- The initial PSAR when a trend turns up is the lowest low of the previous downtrend.
42. **trend_psar_down**
- **Calculation:** Similar to `trend_psar_up`, but for when the trend is downward. The calculation involves the previous period's SAR, the lowest low (EP) during the current downtrend, and the acceleration factor (AF). The formula for a downtrend is:
- `PSAR = Previous PSAR - AF * (Previous PSAR - EP)`
- The initial PSAR when a trend turns down is the highest high of the previous uptrend.
43. **trend_psar_up_indicator**
- **Calculation:** This is a binary indicator that signals when the Parabolic SAR switches to below the price, indicating a potential uptrend. If the current PSAR value is below the current price, it signals an uptrend.
- `PSAR Up Indicator = 1 if Current PSAR < Current Price else 0`
44. **trend_psar_down_indicator**
- **Calculation:** This is a binary indicator that signals when the Parabolic SAR switches to above the price, indicating a potential downtrend. If the current PSAR value is above the current price, it signals a downtrend.
- `PSAR Down Indicator = 1 if Current PSAR > Current Price else 0`
### 1. others_dr (Daily Return)
- **Definition:** Daily Return measures the percentage change in the price of a financial instrument from one day to the next. It is a simple way to gauge the day-to-day fluctuation in the price.
- **Calculation:** The formula for calculating the Daily Return (`others_dr`) is:
- `Daily Return = [(Current Day's Close - Previous Day's Close) / Previous Day's Close] * 100`
- This calculation provides the return for a specific day as a percentage change from the previous day's closing price.
### 2. others_dlr (Daily Log Return)
- **Definition:** Daily Log Return is another way to measure the price change of a financial instrument, using the natural logarithm. Log returns are useful for mathematical analysis, particularly because they are time additive.
- **Calculation:** The formula for calculating the Daily Log Return (`others_dlr`) is:
- `Daily Log Return = ln(Current Day's Close / Previous Day's Close) * 100`
- Where `ln` denotes the natural logarithm. Log returns are especially handy in portfolio analysis and are time additive, which means you can sum log returns over time to get a cumulative return.
### 3. others_cr (Cumulative Return)
- **Definition:** Cumulative Return measures the total change in the price of a financial instrument over a specified period. It represents the aggregate effect of price movements on the initial investment over time.
- **Calculation:** The formula for calculating the Cumulative Return (`others_cr`) when starting from 0 and expressed as a percentage might look like this:
- `Cumulative Return = [(Current Price / Initial Price) - 1] * 100`
- This calculation gives the total percentage return on the investment from the beginning of the period to the current date.

# Extending the Connect 4 Project
Implement these features into your version of the Connect 4 project.
1. Locking board after a win. If clicking your board after a winner has been declared causes a stone to be placed, or the winner to be declared again, make it so that clicking the board does nothing.
2. If your project doesn't have one, implement a reset button, so that at any stage in the game, the user can reset the game. When a winner has been declared, overlay a reset button over the board.
3. Implement a way to keep score over various games. For instance, you could have a box that counts the number of games won by black or red in that session.
4. Implement an introduction screen that lets you choose a board size before starting to play.
5. Implement a way to undo a move with an button next to the board.
6. Implement a way to _replay_ the game once it's over. That is, the moves played during the game should appear quickly on screen, showing you every move that was played.

Subject: [PATCH 5/5] Add linear filter
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org
X-Lkml-Link: https://lkml.org/lkml/2009/1/13/513
From: Nelson Castillo <arhuaco@freaks-unidos.net>
* Linearly scale touchscreen values.
* Expose the constants for the linear transformation using sysfs.
This patch allow programs to gather data directly from
/dev/input/eventX. This is optional, you can use TSLIB
to do the linear transformation if you prefer.

# Getting Started
## Creating a Python File
We can make a simple Python program to do some maths for us. Start by opening a folder in VS Code.
Now, using either Explorer (Windows) or Finder (Mac), create a folder named "python-exercises." Make sure the folder is in a location that is easy to remember. Now open the folder and click "Select Folder".
Now we can see that this folder has been opened with VS Code. Click on the "New File" icon to create a new file within the folder.
Name this file "calculator.py". By giving it the `.py` extension, VS Code knows to treat it as a Python file. This will cause the new file to then open in the editor area.
## `print()` and Using Python as a Calculator
Now enter the code `2 + 2` in your `calculator.py` file and save it. Ctrl / Command + S is a useful shortcut for saving. Your window should now look like this:
Now we can run our code. We can do this by pressing the Run / Play button in the upper-right corner of the editor region. This will lead to a terminal pane being opened.
The information in the terminal is telling us is that the base Conda / Mamba Python was used to run our file. However, we don't see anything else because this particular file did not generate any output. If we want to see the _result_ of `2 + 2`, we need to use Python's `print()` command.
Now, instead have the code run `print(2 + 2)` and then save your file and run it again.
In Python, `print()` is a built-in command used to display output to the console. It takes zero or more values and displays them as text.
> **EXTRA**: Try using the division `\` , floor division `\\`, multiplication `*`, modulo `%`, and power `**` operators to perform other calculations.
### Auto Complete and Parameter Hints
As you were typing out the `print()` command earlier, you may have noticed a box appear with a list of items. At first it's a list of items beginning with p, and then a list of items with the letters p and r in them, and so-on. This is a feature found in many IDEs known as Auto Complete. The purpose of Auto Complete is to save you some extra keystrokes by presenting you with a list of things it thinks you are in the process of typing out. If the item at the top of the list is what you're after then you can hit the Enter key and the rest will be entered in for you.
In the example below, just the letters "pri" are typed out. By pressing Enter, Auto Complete then takes care of the rest and finished writing out the command for me.
Another helpful features in IDEs is Parameter Hints. This gives us a description of a command we are working with and some guidance on how it should be used.
As you code more in Python, you'll find yourself using more commands that need to be used in a specific way and that expect its inputs to be given in a specific order. Getting a reminder from the IDE on how this should be done can save a bit of Googling time.
## Comments
When you run Python code, something called the **Python Interpreter** converts Python code into something the machine can understand. When the interpreter encounters the # symbol it ignores this symbol and any text following it. Comments allow you to clarify your code, which can be especially helpful for your future self or other people you are working with. Getting into the habit of writing comments helps make your code more maintainable in the long-run.
```python
# this bit of text will not be run
print(1 + 1) # this print statement will be run, but this comment will not
```
## Summary
- VS Code can be used to manage Python projects containing multiple files.
- Python can perform basic maths.
- The `print()` command in Python can display information on our terminal.
- Auto Complete helps shorten the process of typing out something while coding.
- Parameter Hints remind us how a command should be used, and what inputs it's expecting.
- Commenting your code makes it easier to use and understand.
