JENKINS DOES NOT TERMINATE ON JEST TEST
-Did this: add --forceExit to package.json
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom --forceExit",
"eject": "react-scripts eject"
}
-Result: Didn't work
-Conclusion: Avoid using jest for testing with Jenkins(except for manual testing)
-Action: Use Mocha instead.
First setup docker registry and install files by running
#installed in this order
create-react-app
jenkins

<file_sep># easyhttp
This is a sample implementation of an HTTP library from the course Modern JavaScript From The Beginning by [@bradtraversy](https://github.com/bradtraversy). This repository is for learning objectives only.
To use the library just put it in your HTML file with the following markup: `<script src="easyhttp3.js"></script>` jubt before the closing `</body>` tag.
## Intantiate the EasyHTTP object:
```javascript
const http = new EasyHTTP();
```
## Calling GET method:
Gets a resource by its corresponding URL.
```javascript
http.get(url)
```
**URL:**
The resource to be called.
**Returns:**
It returs a promise object with *data* and *error* objects so you can call it asychronously.
* Data - the response data in JSON format.
* Error - any error message.
Example:
```javascript
http.get('https://jsonplaceholder.typicode.com/posts')
.then(data => console.log(data))
.catch(err => console.log(err));
```
## Calling POST method:
Adds a new resource by its corresponding URL.
```javascript
http.post(url, data)
```
**URL:**
The resource to be called.
**Data:**
The data to be sent in JSON format.
**Returns:**
It returs a promise object with *data* and *error* objects so you can call it asychronously.

# WeatherPy
Creating a Python script to visualize the weather of 500+ cities across the world of varying distance from the equator. To accomplish this, you'll be utilizing a simple Python library, the OpenWeatherMap API, and a little common sense to create a representative model of weather across world cities.
Objective is to build a series of scatter plots to showcase the following relationships:
- Maximum Temperature (F) vs. Latitude
- Humidity (%) vs. Latitude
- Cloudiness (%) vs. Latitude
- Wind Speed (mph) vs. Latitude
Final notebook :
- Randomly select at least 500 unique (non-repeat) cities based on latitude and longitude.
- Perform a weather check on each of the cities using a series of successive API calls.
- Include a print log of each city as it's being processed with the city number, city name, and requested URL.
- Save both a CSV of all data retrieved and png images for each scatter plot.

# WarGame-Basic
A card war game android application - Basic version
Upon starting the application, a deck of cards will be created, shuffled and split into two halves, one for each player.
Pressing the Play button will deal the next card in each deck.
The player with the higher score will gain a point, if tied - no one gets a point.
After 26 turns, the game activity will close and a results activity screen will open.
In this screen, the winner and the highest score will be shown.
Pressing the 'Restart' button will close the results activity, and re-open the game activity, thus restarting the game.
Pressing the 'Exit' button will shut down the activity, and as there are no open activities, close the application.

refs/heads/master | <file_sep># RedisResourceMap
COVID-19 Resource Dashboard is a project leveraging the power of RediSearch, RedisGears, and Redis PubSub to create a live-updating, crowdsourced dashboard to connect places with excess supply of masks, oxygen, and vaccines to places lacking in such supplies. Users can add locations to indicate both excess supply and required resources, and the RedisGears matching engine will utilize the power of RediSearch geospatial querying to match up supplies with requirements.
## How data is stored
- Resource and location data are stored as documents in the RediSearch format. They contain the fields:
- masks (Numerical)
- vaccines (Numerical)
- oxygen (Numerical)
- updated (Numerical)
- coords (Geo)
## How data is processed
- Data is inserted (as RediSearch documents) using the `HSET` command. Details on query construction are abstracted away with the `RediSearch` Python API, but the fields are as mentioned above
- Data is queried using `FT.SEARCH`:
- Since this uses geospatial querying, heavy use of `GEORADIUS`/geospatial query syntax is used
- Example query: `FT.SEARCH @coords[long lat radius km] FILTER masks 1 10000 INKEYS 1 -76,40`
- Update are published with PUBLISH and read with SUBSCRIBE
- New data is processed with RedisGears async jobs, and sent via Redis PubSub on either the `new_data` channel or `match_data` channel (if a resource is matched)
- Example: `PUBLISH new_data "{masks: 10, ...}"`, `SUBSCRIBE new_data`
## Screenshots
### Architecture Diagram
## Instructions
- Run the Redis labs RedisModules docker image: `docker run -p 6379:6379 redislabs/redismod`
- Using pip and python 3.7, install the requirements in `requirements.txt`, or create a Conda environment using `conda env create --file conda_env.yml` and then run `conda activate redis` to activate the environment.
- Run `python server.py` from `backend/`. This will create a server accessible at `localhost:5000`
- Install node.js and npm if you do not already have it installed (see [https://nodejs.org/en/download/](https://nodejs.org/en/download/)). Then run `npm install` and `npm start` from `frontend/`, and the React frontend should appear in your web browser at `localhost:3000/admin/dashboard`

* @function groupBy()
* @author <NAME> <<EMAIL>>
* Groups up the 'data' into a tree object based on the 'groups' parameter.

# TCP sockets in Java
TCP sockets enable communication between programs within the same machine or across different machines.
Data can be sent/received using the regular Java OutputStream/InputStream.
```
Socket s = connect();
InputStream in = s.getInputStream();
OutputStream out = s.getOutputStream();
// send and receive data from the connected program
```
## Estabilishing a connection
The connection is established between two programs.
One of the programs (the server) will wait for an incoming connection and accept it.
The other program (the client) will create an outgoing connection to the server.
To connect to the server, the client needs to know the server's **IP address** and **port number**.
An IP address uniquely identifies a machine in the network.
It is usually written as 4 dot-separated integers, e.g. `192.168.1.1`.
A machine can have several IP addresses if it has several network cards (some may be virtual).
Each machine also has a loopback IP address called *localhost*: `127.0.0.1`.
This can be used to refer to the local machine and make connections to it.
Each machine can have multiple programs running on it, each of them creating and accepting connections.
Port numbers are used to differentiate between different connections.
A program can claim any free port number for any local IP address and use it to accept and create connections.
The connections are identified by the quadruples of { local ip, local port, remote ip, remote port }.
One way to think about the IP addresses and ports is to use the apartment building analogy.
The IP address is the building's address.
The port number is the mailbox number in a building.
Different owners (programs) can own different mailboxes in a building (IP).
When a message arrives at some building (IP), the house keeper (operating system) will deliver the message to the right mailbox (program) by looking at the mailbox number (port number).
Incoming connections can be accepted in Java using the `ServerSocket` class:
```
int portNumber = 8080;
// allocate port on all available IP addresses
try (ServerSocket ss = new ServerSocket(portNumber)) {
// wait for an incoming connection
try (Socket socket = ss.accept()) {
// use connection
}
}
```
What's the difference between `Socket` and `ServerSocket`?
* A ServerSocket **holds a queue of incoming connections** on the specified port.
It does not represent a connection.
* A Socket **represents a connection**.
It is defined by its { local ip, local port, remote ip, remote port } quadruple.
Outgoing connections can be created in Java using the `Socket` class:
```
// connect to port 8080 of the local machine using the loopback address
// note that 8080 is the "remote port". local port number is chosen automatically (randomly)
try (Socket socket = new Socket("localhost", 8080)) {
// use the input/output streams here
}
```
## Tips and tricks
* This repository includes a runnable example.
Start the server first.
Start the client while the server is still running, otherwise there is nothing to accept the client's connection.
* It is possible to accept multiple connections from a single `ServerSocket`.
Usually `accept()` is called in some sort of loop.
* Sockets accepted from the same ServerSocket use the same local port, but the remote ip/port are different.
* InputStream methods can block when trying to read more than the remote has sent.
To see what the code is waiting for, use the "Thread dump" button in the IDE debugger panel or the *jstack* command line utility.
* Ports numbered 1-1024 are *privileged ports*, often used to run system services.
Trying to use these can throw an exception unless the program is runnings with admin rights.
Use a higher numbered port instead.
* You can check your machine's IP using these commands: `ip addr` (Linux), `ifconfig` (Mac) or `ipconfig` (Windows).
* Sometimes the local firewall configuration prevents accepting connections from remote machines (Windows or locked down Linux).
Sometimes the router configuration prevents creating connections to other machines in the local network (e.g. university wifi).
## How to organize network communication
The most common way to communicate over the network is to use the [request-response pattern](https://en.wikipedia.org/wiki/Request%E2%80%93response).
The client sends a message to the server and the server sends a reply.
The client won't send a new message before receiving a reply for the previous one.
The server never sends any non-reply messages to the client.
Another important aspect in communication is the message syntax.
A socket only provides the input/output streams that transfer bytes.
The syntax describes how the data is encoded into bytes so it can be later reconstructed.
### Example syntax
Here's an example of network communication between a service that can register students to courses and a client.
The first byte of a message contains the message type.
The next bytes contain the message content depending on the message type.
1) the client sends a byte array `[1,4,155,141,162,164]`.
the first byte shows the message type `1` for "new registration".
the second byte `4` is the length of the student's name, followed by 4 bytes `[155,141,162,164]` for a UTF-8 encoded string "mart".
2) the server responds with a single byte `[2]` - the message type for "registration ok".
alternatively the server could respond with `[3,155,..]`, where the type `3` is for "registration error", followed by `155` for error length, followed by 155 bytes containing the bytes for the error string.
3) the client sends a new message..
The key to a good syntax is to add a length prefix to every variable length piece of data.
Otherwise the receiver will have no way of knowing how much it needs to read.
### Using data streams
Java has the DataOutputStream and DataInputStream classes with many useful helper methods.
Make use of them!
Sending strings is one of the most common operation.
Let's take a look on how it could be done using data streams.
```
void writeStrings(DataOutputStream out) throws Exception {
// bad example; don't do this!
byte[] m1bytes = "message1".getBytes("UTF-8");
byte[] m2bytes = "message2".getBytes("UTF-8");
out.write(m1bytes);
out.write(m2bytes);
}
```
This code successfully sends two strings to the output stream.
However, how can the receiver reconstruct this data?
How could they find out where one string ends and another starts?
There is not way to make such approach work reliably.
The solution is to **send a length prefix** before each variable length piece of data.
```
void myWriteUTF(DataOutputStream out, String str) throws Exception {
byte[] encoded = str.getBytes("UTF-8"); // always specify encoding
out.writeInt(encoded.length); // int is always exactly 4 bytes
out.write(encoded);
}
String myReadUTF(DataInputStream in) throws Exception {
int length = in.readInt(); // read exactly 4 bytes
byte[] encoded = in.readNBytes(length); // useful method!
return new String(encoded, "UTF-8");
}
```
The above methods are so commonly needed that they were built into the data stream classes.
The above could be replaced with simply `out.writeUTF(str)` and `in.readUTF()`.
Datastreams make it easy to write more complex messages as well.
Sending a request to get a student's grade for a course:
```
static final int TYPE_GET_GRADE = 4;
void sendGetGradeRequest(DataOutputStream out, String studentId, int courseId) throws Exception {
out.writeInt(TYPE_GET_GRADE);
out.writeUTF(studentId);
out.writeInt(courseId);
}
```
Reading the request on the server side:
```
static final int TYPE_GET_GRADE = 4;
static final int TYPE_GRADE_OK = 5;
static final int TYPE_GRADE_ERROR = 6;
void processRequest(DataInputStream in, DataOutputStream out) throws Exception {
int type = in.readInt();
if (type == TYPE_GET_GRADE) {
processGetGrade(in, out);
} else {
throw new RuntimeException("unknown type " + type);
}
}
void processGetGrade(DataInputStream in, DataOutputStream out) throws Exception {
String studentId = in.readUTF();
int courseId = in.readInt();
if (hasCompletedCourse(studentId, courseId)) {
out.writeInt(TYPE_GRADE_OK);
out.writeDouble(getGrade(studentId, courseId));
} else {
out.writeInt(TYPE_GRADE_ERROR);
}
}
```
A few issues to avoid:
* instead of `writeUTF(name + ";" + description)` use `writeUTF(name); writeUTF(description);`.
this way there's no need split the strings manually and the code also works with names that include the `;` symbol.
* instead of `writeUTF(Integer.toString(123))` use `writeInt(123)`.
always try to use the right type and avoid unnecessary string conversions.
* use `writeInt(123)` instead if `write(123)`.
the parameter of `write` is an int (4 bytes), but it only sends a single byte (wtf java).
### Use xml/json for more complex data structures
When you need to send a more complicated object over the network, then manually encoding and decoding it to/from bytes can be quite annoying.
Encode the object into a string using [gson](https://github.com/google/gson/blob/master/UserGuide.md#TOC-Object-Examples), then send the string as the message value.
Gson can decode the string back into the object on the receiving side.
The string should still be wrapped with the regular type-length-value syntax.
Note that string encoded messages are very space-inefficient.
## Notes on IPv6
There are two formats of IP addresses: IPv4 and IPv6.
The old IPv4 addresses (e.g. `192.168.1.1`) are essentially 32-bit integers (the dot separated string is just a convenient notation).
There are more computers on the planet than there are 32-bit integers, which causes all sorts of problems.
The new IPv6 addresses are 128-bit integers that look something like `2001:0db8:0000:0000:0000:ff00:0042:8329` (8 groups of 16 bits each).
The world is slowly moving to use these instead of IPv4.
Some things to keep in mind when using IPv6 addresses:
* leading zeros from any group can be removed
* consecutive groups of zeroes can be omitted.
this can only be done once in an address, otherwise it's impossible to reconstruct the address.
* the address is often wrapped in brackets to avoid confusing the port number separator with the address group separators (both use `:`)
For example, an URL containing the above address could be written as `https://[2001:fd00:a516:7c1b:17cd:6d81:2137:bd2a:2c5b:42:8329]:8443/`.
Note that the three groups of zeros have been omitted and all leading zeros have been removed.
The port number 8443 is placed outside the brackets.

# Description:
The aim of this project is to predict the forest fires to decrease the harm that would occur by these fires.
Different machine learning methods including Multilayer Perceptron (MLP) have been used to detect the forest fires;
however, in this project We are planning to apply MLP with more than one hidden layer(16,8) with 'relu' activation function and also apply to Levenberg-Marquardt (LM)
algorithm to predict forest fires and compare the result of them. The RMSE(Root Means Square Error) values of the models have been computed to determine the
performance of the forest fires prediction models.
# Team & Roles:
<NAME>(370709069) and <NAME>(170709055). We both worked in every places such as report and source code e.t.c.
# Structure:
You can reach source code which name is finalProject.py and csv file which name is forestfires.csv.
# Language, version, and main file:
We used python language on this project. One of us worked python 3.7 version, the other one worked python 3.9 version. The main file is finalProject.py .
# Additional:
Report.tex file is in the latex folder
Also, We would like you to know in our commiting part sultanguvenbas and U170709055 are the same person. We do not know why some commits taking from sultanguvenbas, some commits taking from U170709055. However they are the same person as you can guest. You can check it though the insights -> network part. The same problem occured akglali and U370709069.

# Polyglot Python Development Starter (Containers)
As a Polyglot Software Engineer, a significant part of your work will require you to ensure that your code always works consistently no matter where it is run. Please follow through these instructions to get set up in Visual Studio code with a sandboxed 'container' environment.
For a background on containers in VSCode - please read **[VS Code Remote - Containers](https://aka.ms/vscode-remote/containers)** extension in a few easy steps.
## Pre-requesites
- Windows 10 (Depending on your experience you may be able to follow along on other operating systems)
- **[VsCode for Windows](https://code.visualstudio.com/Download)**
- **[Git for Windows](https://git-scm.com/download/win)**
## Getting a copy of this code - the right way
- Open this repo's page on GitHub.com
- Make sure you have a personal GitHub account for your learning and you are logged in.
- Instead of Cloning this repo - Fork it as a Private repo for yourself
- Clone your own fork of this repo* to ~/localGIT/[this repo]
- Open the local folder in VSCode
- After a moment VSCode should detect that you have a container configuration and offer to let you 'Restart in Container' - click this.
- If you've not used containers before see the 'Setting up the development container' section.
## Setting up the development container
Follow these steps to open this sample in a container:
1. Since this is likely your first time using a development container, please follow the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started).
2. To use this repository, open the repository in an isolated Docker volume (we'll cover these steps in the workshop):
- Fork this repository on your own GitHub
- Clone your fork of this repository to your local filesystem.
- Follow the prompts to setup your Docker instance
- Post any questions to the channel.
## Things to try
Once you have this sample opened in a container, you'll be able to work with it like you would locally.
1. **Edit:**
- Open `src/App.python`.
- Try adding some code and check out the language features.
2. **Terminal:** Press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>\`</kbd> and type `uname` and other Linux commands from the terminal window.
3. **Build, Run, and Debug:**
- Open `src/App.python`.
- Add a breakpoint.
- Press <kbd>F5</kbd> to launch the app in the container.
- Once the breakpoint is hit, try hovering over variables, examining locals, and more.
4. **Run a Test:**
- Open `src/test/AppTest.python`.
- Put a breakpoint in a test.
- Click the `Debug Test` in the Code Lens above the function and watch it hit the breakpoint.
> **Note:** We'll be adding features to this as we go and you'll be given access to new branches in this repository to base your ideas on.

refs/heads/master | <file_sep>分享几个实验的数据处理小程序。具体保留有效数字位数自行参照要求，一般为3~4位有效数字。
实验平台地址：http://192.168.127.12/
### 使用方法：
（C++）在可执行文件的目录下，将仿真实验测得数据存入in.txt文件中。各数据间以空格分隔。
输入数据格式可参考解压所得的in.txt数据，用实际测得数据覆盖即可。in.txt保存完毕后，运行exe文件，秒出结果。
（Python）按提示输入数据<file_sep>#include <iostream>

<file_sep>#HOW TO USE DATABASE
1. Go to CMD and move to folder of project
2. Type
- php artisan migrate
- php artisan db:seed
<file_sep>#How to do
1. Go to console CMD:
- cd /d d:\Your xampp folder\htdocs
- git clone <EMAIL>:webdevqn/tdc.git
- cd tdc
- composer install
2. Go to folder dayvahoc copy .env-example to be a new file named .env, if IDE does not show hidden files, go Google to do it.
3. Open Xampp and start Apache and MySQL to create a new database: tdc in unicode UTF8
4. Open .env and configurate suitably the database name, user name, password and save them: commonly, we use:
- database: tdc
- username: root
- password: (do not write anything)
5. Go to Disk C > Windows > System32 > Drivers > etc.
6. Copy hosts file in etc to Desktop and configurate there, then copy back to etc folder to replace.
7. The content which is needed to change is: Add a new line to get a virtual domain tdc.vu, any name you want is ok.
- The content to add is: 127.0.0.1 tdc.vu
8. Remember copy back to etc folder and surely overwrite it.
9. Stop Xampp
10. Go to Xampp > Apache > Conf > extra
11. Open file v-host and configurate it.
12. Copy 2 lines into its bottom: 1 for localhost, 1 for tdc.vu
DocumentRoot "Your Path To Xampp/xampp/htdocs"
ServerName localhost
DocumentRoot "Your Path To Xampp/xampp/htdocs/tdc/public"
ServerName tdc.vu
13. Restart Xampp
14. Open browser and open tdc.vu to get the Laravel Screen<file_sep><?php

- Kan du tilføje ost til dit køleskab?
- Kan du redigere udløbsdatoen på ostene?
- Kan du se hvor mange oste du har tilføjet?
- Kan du se udløbsdatoen på dine varer?
- Kan du oprette en 0.5 l vand?
- Kan du finde en opskrift på pandekage?
- Kan du slette en vare?
- Kan du finde en Faxe Kondi vha. stregkoden på dåsen?
- Kan du sortere efter udløbsdato?

import math
import time
from blinkt import set_pixel, show
# set_pixel(4,0,255,0)
# show()
# `set_pixel` takes an optional fifth parameter; the brightness from 0.0 to 1.0.
#
# `set_pixel(pixel_no, red, green, blue, brightness)`
#
# You can also change the brightness with `set_brightness` from 0.0 to 1.0, for example:
# from blinkt import set_brightness
#
# set_brightness(0.5)
# show()
set_pixel(3,255,255,0)

2. <NAME> (<EMAIL>)
Design
------
> 1. To implement `Filesystem::debug`, you will need to load the file system
> data structures and report the **superblock** and **inodes**.
>
> - How will you read the superblock?
> - How will you traverse all the inodes?
> - How will you determine all the information related to an inode?
> - How will you determine all the blocks related to an inode?
Response.
To read the superblock, we will call read(0,data) to read the data in the first block, then cast that data pointer to the Block union. Then, we can read the superblock fields through the "Super" member. To traverse all the inodes, we will first read the number of inodes from the SuperBlock. Then, we can read the inodes by, starting at block 1, iterating through the inodes by using the Inodes[] member of the union. We will determine all the information related to an inode simply by reading the fields from the struct Inode in the Inodes array. All of the blocks related to the inode are the ones in the Inode.Direct array, as well as any in the block pointed to by the Inode.Indirect field.
> 2. To implement `FileSystem::format`, you will need to write the superblock
> and clear the remaining blocks in the file system.
>
> - What pre-condition must be true before this operation can succeed?
> - What information must be written into the superblock?
> - How would you clear all the remaining blocks?
Response.
Before the operation can succeed, the disk must not be mounted already. When formatting, the magic number, number of blocks, number of inode blocks, and number of inodes must be written. We would clear all the remaining blocks by iterating across all of the inodes and setting the Valid member to zero (i.e. false)
> 3. To implement `FileSystem::mount`, you will need to prepare a filesystem
> for use by reading the superblock and allocating the free block bitmap.
>
> - What pre-condition must be true before this operation can succeed?
> - What sanity checks must you perform?
> - How will you record that you mounted a disk?
> - How will you determine which blocks are free?
Response.
Before the operation can succeed, the disk must not be mounted already. We must check the following: that the magic number is correct, that the number of blocks described by the superblock is the same as the number of blocks on the disk, that the number of inode blocks is reasonable, and that the number of inodes matches the total number of inodes that would be in that many blocks. We will record that we mounted a disk by incrementing the "Mounts" member variable in the disk. We will determine which blocks are free by scanning the inodes and seeing which blocks are pointed to by valid inodes.
> 4. To implement `FileSystem::create`, you will need to locate a free inode
> and save a new inode into the inode table.
>
> - How will you locate a free inode?
> - What information would you see in a new inode?
> - How will you record this new inode?
Response.
We will locate a free inode by performing a linear scan along the inodes and finding the first one that is free. We would see in a free inode Valid set to zero. The other fields may be garbage. We would record the new inode during create by seting Valid to 1, and setting each other field of the Inode struct to its proper value (Size, filling Direct with as many pointers as needed, and setting Indirect to a block if necessary, zero otherwise).
> 5. To implement `FileSystem::remove`, you will need to locate the inode and
> then free its associated blocks.
>
> - How will you determine if the specified inode is valid?
> - How will you free the direct blocks?
> - How will you free the indirect blocks?
> - How will you update the inode table?
Response.
We will determine if the specified inode is valid by checking its Valid member. We will free the direct blocks by zeroing all of the blocks pointed to by each entry of the Direct array. We will free the indirect blocks by going to the block that is pointed to by the Indirect member, and iterating through all of the pointers it contains, zeroing the data in the blocks that each pointer points to. Finally, we can clear the data members of the inode struct and set Valid to zero.
> 6. To implement `FileSystem::stat`, you will need to locate the inode and
> return its size.
>
> - How will you determine if the specified inode is valid?
> - How will you determine the inode's size?
Response.
We will determine if the specified inode is valid by checking the Valid member of the inode struct. We will determine the inode's size by reading the Size field of the inode struct.
> 7. To implement `FileSystem::read`, you will need to locate the inode and
> copy data from appropriate blocks to the user-specified data buffer.
>
> - How will you determine if the specified inode is valid?
> - How will you determine which block to read from?
> - How will you handle the offset?
> - How will you copy from a block to the data buffer?
Response.
We will determine if the specified inode is valid by checking the Valid member of the inode struct. We will determine which block(s) to read from by finding how many blocks in the specified offset would be. If that block offset is less than the number of blocks in Direct, we can simply read from the block pointed to by that entry of Direct. Otherwise, we need to scan through the indirect block for the data pointer. Once we find the data block to read from, we will handle the offset by starting the read from (offset % BLOCK_SIZE) bytes in. We will copy from a block to the data buffer using memcpy.
> 8. To implement `FileSystem::write`, you will need to locate the inode and
> copy data the user-specified data buffer to data blocks in the file
> system.
>
> - How will you determine if the specified inode is valid?
> - How will you determine which block to write to?
> - How will you handle the offset?
> - How will you know if you need a new block?
> - How will you manage allocating a new block if you need another one?
> - How will you copy from a block to the data buffer?
> - How will you update the inode?
Response.
We will determine if the specified inode is valid by checking the Valid member of the inode struct. We will determine which block(s) to write to by finding how many blocks in the specified offset would be. If that block offset is less than the number of blocks in Direct, we can simply write to the block pointed to by that entry of Direct. Otherwise, we need to scan through the indirect block for the data pointer. Once we find the data block to write to, we will handle the offset by starting the read from (offset % BLOCK_SIZE) bytes in. To allocate a new block if we need one, we will add a new pointer to the Direct array if it has room, or to the indirect block if it doesn't. We will copy from a block to the data buffer using memcpy. We will update the size field of the inode if we grew the data at all (instead of overwriting), and update the Direct array if we allocated a new direct block, and the Indirect pointer if we allocated the indirect block

<file_sep>There is a folder called "web_server" in lab5 in the home direcory where all the necessary files are kept.
In case of single threaded webserver when we execute the given example, ie. "wget -P test1 -nd -p localhost:7090/index.html" and "wget -P test2 -nd -p localhost:7090/index.html",
we observe that at a time only one of the 2 requests is processed while the other has to wait.
In the modified multi-threaded webserver when we execute the same example, we observe that both requests are processed simultaneouly.
Currently there is an upper limit of max 10 threads, which can be easily changed as per needs.
This means currently at max 10 threads can execute simultaneously.
To compile and build the dynamic webserver use "make webserver_dynamic", then to run it use "./webserver_dynamic 7200". After building and executing the dynamic server, start two new sessions and then execute the examples given, ie., "wget -P test1 -nd -p localhost:7090/index.html" and "wget -P test2 -nd -p localhost:7090/index.html".
It can be seen that both requests are processed simultaneously.
After the completion if we wish to delete the executable file for dynamic webserver then we may use "make clean_dynamic".
Similarly we can use "make weebserver_pool"to compile and build the thread pool server. to run we use "./webserver 7200 <number of threads> <scheduling mode>", available scheduling modes are FCFS and SFF.
We may use the examples as used in the dynamic thread server to test this program, or directly use the shell script given.
After the completion if we wish to delete the executable file for thread pool webserver then we may use "make clean_pool".
The results obtained after running the test shell script file is as follows :
"Total runtime dynamic with 10 parallel requests is 107.197686303
Total runtime pool with 10 parallel requests with FCFS and 5 pool threads is (1st test) 140.746285616
Total runtime pool with 10 parallel req with SFF and 5 pool threads is (2nd test) 136.123134186".<file_sep>#include <stdio.h>

<file_sep># Overview
`"binomial"` is a self-created R package that implements functions for calculating probabilities of a Binomial random variable, and related calculations such as the probability distribution, and expected value, variance, etc.
## Steps
##### 1) Calculate the number of different combinations given certain number of trials and successes.
##### 2) Find the probability given certain number of trials and successes
##### 3) obtain a dataframe given certain number of trials and successes
##### 4) Plot the histogram of above dataframe
##### 5) Calculate the cumulative probability
##### 7) Create binomial variable using given number of trials and successes
##### 8) Obtain a summary of binomial variable above
##### 9) Calculate several statistics of binomial variable above
`bin_mean` gives the mean of given binomial distribution.
`bin_variance` gives the variance of given binomial distribution.
`bin_mode` gives the mode of given binomial distribution.
`bin_skewness` gives the skewness of given binomial distribution.
`bin_kurtosis` gives the kurtosis of given binomial distribution.
## Motivation
This package is used to illustrate the usage and concepts of binomial package.
## Installation
Install the development version from GitHub via the package `"devtools"`:
```r
# development version from GitHub:
#install.packages("devtools")
# install "binomial" (without vignettes)
devtools::install_github("stat133-sp19/hw-stat133-xihuanzhang/workout03/binomial")
# install "binomial" (with vignettes)
devtools::install_github("stat133-sp19/hw-stat133-xihuanzhang/workout03/binomial", build_vignettes = TRUE)
# If it doesn't work, add 'force = TRUE'
devtools::install_github("stat133-sp19/hw-stat133-xihuanzhang/workout03/binomial", force = TRUE)
```
## Usage
step 1) loading the package using library(binomial)
step 2) test the functions
step 3) provide desired number of trials, number of sucesses and probability for one single trial.
step 4) the binomial package will return the results corresponding to given inputs
The content below provides some specific examples using binomial package
```{r}
#for example, we play 5 times and expect 2 successes
bin_choose(n=5,k=2)
#We generate the bin_probability function using bin_choose function above. Using the functions below, we can calculate the probability of winning 2 times in 5 trials with success probability of 0.5 for each single trial.
bin_probability(success = 2, trials = 5, prob = 0.5)
#Using given number of trials and successes, we can obtain a data frame containing all the results(probability) corresponding to consequtive number of trials from 0 to the given number of trials
dis1 <- bin_distribution(trials = 5, prob = 0.5)
dis1
#plot the data frame above
plot(dis1)
#Using given number of trials and successes, we can obtain a data frame containing all the results(probability and cumulative probability) corresponding to consequtive number of trials from 0 to the given number of trials
bin_cum<- bin_cumulative(trials = 5, prob = 0.5)
bin_cum
#plot the bin_cum we obtained above.
plot(bin_cum)
#obtian some statistics of our generated binomial variables
bin_mean(10,0.5)
bin_variance(10,0.5)
bin_mode(10,0.5)
bin_skewness(10,0.5)

Cooking Recipe
==============
Use an unordered list(of bullets) to list the ingredients.
==========================================================
- 2 cups plus 3 tablespoons (285 grams) all-purpose flour
- 1 1/2 teaspoons baking soda
- 1/2 teaspoon fine sea salt
- 1 cup (200 grams) granulated sugar
- 1/2 cup (110 grams) coconut oil, warmed just enough to liquefy
- 1 1/2 cups full- or low-fat coconut milk (see Note)
- 1 tablespoon (15 ml) plain vinegar
Use another unordered list to list any "special"kitchen tools that are needed.
==============================================================================
- Oven
- Pan
Describe the steps of the recipe
================================
> Heat oven to 350 degrees F. Line the bottom of 9-inch round cake pan with a fitted round of parchment paper and coat the bottoms and sides with nonstick cooking spray.
> Whisk together flour, baking soda, salt and granulated sugar in the bottom of a large mixing bowl. Add coconut oil, coconut milk, and vinegar and whisk until batter is smooth.
> Pour into prepared pan. Bake for 25 to 30 minutes \[updated to note: it’s sounding in the comments like it’s taking some people a bit longer — it’s not done until the center is set, even if it’s longer than it took me\], or until the top is springy and a tester inserted in the center comes out batter-free. Cool the cake in the pan on a wire rack for 10 minutes, then cut around it with a knife to ensure it is loosened and flip it out onto a cooling rack to cool the rest of the way.
> If you wish to make a glaze: Whisk together 3/4 cup powdered sugar with 1 to 2 tablespoons of the leftover coconut milk, adding a little at a time, until it is smooth but not too runny. Add a pinch of salt, if you wish. Once cake is fully cool, spread over the top of the cake and smooth to the edges with a knife or small offset spatula, where it will find its way down the sides decoratively on its own. I added some white confetti sprinkles, but toasted coconut chips would be nice here too.
Include an image to show the appearance of the meal.
====================================================
Is there an special season of the year for it?
==============================================
> No.
Are there variations of the recipe? Using other ingredients?
============================================================
> Yes.
Euclidean Distance
==================
> Definition
> The Euclidean distance between points p and q is the length of the line segment connecting them ($\\overline{\\textbf{p,q}}$). In Cartesian coordinates, if **p** = (*p*<sub>1</sub>,*p*<sub>2</sub>,…,*p*<sub>*n*</sub>) and **q** = (*q*<sub>1</sub>,*q*<sub>2</sub>,…,*q*<sub>*n*</sub>) are two points in Euclidean n-space, then the distance (d) from to , or from to is given by the Pythagorean formula:
> The position of a point in a Euclidean *n* -space is a Euclidean vector. So, p and *q* may be represented as Euclidean vectors, starting from the origin of the space (initial point) with their tips (terminal points) ending at the two points. The Euclidean norm, or Euclidean length, or magnitude of a vector measures the length of the vector:
$\\| \\mathbf {p} \\| = \\sqrt { p \_ {1} ^ {2} + p \_ {2} ^ {2} + \\cdots + p \_{n} ^ {2}} = \\sqrt { \\mathbf {p} \\cdot \\mathbf {p}}$
> where the last expression involves the dot product.

Vignettes are long form documentation commonly included in packages. Because they are part of the distribution of the package, they need to be as compact as possible. The `html_vignette` output type provides a custom style sheet (and tweaks some options) to ensure that the resulting html is as small as possible. The `html_vignette` format:
- Never uses retina figures
- Has a smaller default figure size
- Uses a custom CSS stylesheet instead of the default Twitter Bootstrap style
# Binomial
`"binomial"` is a self-created R package that implements functions for calculating probabilities of a Binomial random variable, and related calculations such as the probability distribution, and expected value, variance, etc.
### 1) Calculate the number of different combinations given certain number of trials and successes.
for example, we play 5 times and expect 2 successes
```{r}
bin_choose(n=5,k=2)
```
### 2) Find the probability given certain number of trials and successes
We generate the bin_probability function using bin_choose function above. Using the functions below, we can calculate the probability of winning 2 times in 5 trials with success probability of 0.5 for each single trial.
```{r}
bin_probability(success = 2, trials = 5, prob = 0.5)
```
### 3) obtain a dataframe given certain number of trials and successes
Using given number of trials and successes, we can obtain a data frame containing all the results(probability) corresponding to consequtive number of trials from 0 to the given number of trials
```{r}
dis1 <- bin_distribution(trials = 5, prob = 0.5)
dis1
```
### 4) Plot the histogram of above dataframe
```{r}
plot(dis1)
```
### 5) Calculate the cumulative probability
Using given number of trials and successes, we can obtain a data frame containing all the results(probability and cumulative probability) corresponding to consequtive number of trials from 0 to the given number of trials
```{r}
bin_cum<- bin_cumulative(trials = 5, prob = 0.5)
bin_cum
```
### 6) Plot the cumulative probability
plot the bin_cum we obtained above.
```{r}
plot(bin_cum)
```
### 7) Create binomial variable using given number of trials and successes
```{r}
bin_var <- bin_variable(trials=5,prob=0.5)
bin_var
```
### 8) Obtain a summary of binomial variable above
```{r}
bin_sum <- summary(bin_var)
bin_sum
```
### 9) Calculate several statistics of binomial variable above
`bin_mean` gives the mean of given binomial distribution.
`bin_variance` gives the variance of given binomial distribution.
`bin_mode` gives the mode of given binomial distribution.
`bin_skewness` gives the skewness of given binomial distribution.
`bin_kurtosis` gives the kurtosis of given binomial distribution.
```{r}
bin_mean(10,0.5)
bin_variance(10,0.5)
bin_mode(10,0.5)
bin_skewness(10,0.5)
bin_kurtosis(10,0.5)

5.2)Narrative
Report
======
- Introduction: Golden State Warriors began in Philadelphia in 1946 and got their inaugural championship in the 1946-1947 season. It holds the name Golden State Warriors since 1971. In history, GSW has won four seasons, including the most recent 2014-2015, 2016-2017 and 2017-2018 seasons. The GSW has raised many famous players, such as <NAME> who got the NBA most valuable player award in the 2015-2016 season. As a competitive team, the GSW attracts much attention from the world, and many people want to know if it can remain champions in the 2018-2019 season. I analyzed their data in the 2016-2017 season to predict if they are going to be the champion in this season.
- Motivation: Since the 2016-2017 season is a recent one, their current strength doesn’t change a lot compared to that season. We can predict the result by analyzing different members’ performance in the 2016-2017 season.
- Background: The 2014-2015 season is a significant turning point for the GSW. They got their first champion after 40 years of obscurity. The GSW started the Steve Kerr era which is the Championship Era since that season. Under the leading of Steve Kerr, the GSW becomes a rising star in the world of basketball. The “famous four” of GSW are <NAME>, <NAME>, <NAME>, and <NAME>, and they all had incredible performance in recent seasons. Plus, <NAME> is also a key player of GSW.
- Data and Analysis: I got those five players’ statistic in the 2016-2017 season from the GitHub website, which includes their game date, shot type, shot distance and many other data. I picked the two points shot statistic and three points shot statistic and made a table.
##### 2PT Effective Shooting % by Player:
``` r
two_points <- filter(name_shottype, shot_type == "2PT Field Goal")
arrange(
summarise(group_by(two_points, name),
total = length(shot_type),
made = sum(shot_made_flag == "shot_yes"),
perc_made = made/total
),
desc(perc_made))
```
## # A tibble: 5 x 4

##### 3PT Effective Shooting % by Player:
``` r
three_points <- filter(name_shottype, shot_type == "3PT Field Goal")
arrange(
summarise(group_by(three_points, name),
total = length(shot_type),
made = sum(shot_made_flag == "shot_yes"),
perc_made = made/total
),
desc(perc_made))
```
## # A tibble: 5 x 4

From the tables above, we can see that <NAME> did 640 two points shots which is the most among five players, and succeed in the percentage of 51.4%. For three points shots, Klay made the second most shots and had got the highest success rate. It’s obvious that Klay’s strategy is to make more shots. Comparing to his two points shot, he did better in three points shots. 
Although <NAME> made 210 two points shots which is the least among five players, he got the highest success rate, 63.8%. Andre also did the least three points shots with a success rate of 36%. Andre did much better in two points shots than three points shots. He focused on the quality more than quantity.
<NAME> got the second place in two points shots success rate and the third place in three points rate. Meanwhile, he attempted more two points shots than three points shots. It turns out that he tended to be a two points shots player. However, both the three points and two points success rate of current season are less than the 2016-2017 season.

<NAME> is a superstar even in such a famous team which has many talented players. As it shows in the table, Stephen did a good job in both two points shots and three points shots. For many players, they got a decreasing success rate when they have more attempts. However, Stephen kept a high success rate at the same time as having many attempts.
<NAME> is also an excellent player. It seems that he got the lowest success rate in both kinds of shots among five players, but his performance is still much better than many players from other teams. The reason he ranked at such a place is that the other four players are the best among top players. He makes huge progress in the current season where he got a 54.9% success rate on two points shots. It is highly likely that he will achieve a higher overall success rate than the 2016-2017 season.
- Discussion: At the beginning of 2018, a talented player De<NAME> joined the GSW, and made the whole team even more competitive. However, it turns out that the GSW is facing some difficulties in the current season. On November 22nd, 2018, the GSW missed Stephen Curry and took their fourth consecutive loss to Oklahoma City Thunder, and they were finally defeated by 95 to 123. It was the first time that <NAME> had a taste of four-game losing streak since he was the coach. The last time when the GSW suffered a four-game losing streak was in the 2012-2013 season. However, they still have the chance to win this season since players still keep a high success rate now. For example, according to the statistic from basketball-reference website, Andre has a three points shots success rate of 64.2% which is higher than his success rate in the 2016-2017 season. Overall, five players all keep a stable performance in this season.
- Conclusion: The GSW has a similar statistic as the 2016-2017 season where they won the championship, so they are a strong candidate for the champion in the 2018-2019 season. Although they are facing a very tough fight, they are still able to improve the situation as long as the coach Kerr set a powerful strategy and all players do as well as usual. Plus, with <NAME>’s return, the Warriors have an even higher possibility to win the championship. In the recent Warriors and Nuggets game, the Warriors created the record of 51-point first quarter and a 142-111 victory at the end. In general, the chances of the Warriors winning this season are great, but it also depends on the Warriors performance in the playoffs. The result gained from past data can only be an estimation or a prediction but can’t be a conclusion since the situation changes in every game. We can never jump to the conclusion before collecting all the data. Do you think the GSW could win the champion again? Who is the MVP in your mind? Let’s stay focus on the Warriors’ performance together! Good luck, Warriors!

<file_sep>* `period:` an NBA game is divided in 4 periods of 12 mins each. For example, a value for `period = 1` refers to the first period(the first 12 mins of the game).
* `minutes_remaining` and `seconds_remaining` have to do with the amount of time in minutes and seconds, respectively, that remained to be played in a givin period.
* `shot_made_flag` indicates whether a shot was made (y) or missed (n).
* `action_type` has to do with the basketball moves used by players, either to pass by defenders to gain access to the basket, or to get a clean pass to a teammate to score a two pointer or three pointer.
* `shot_type` indicates whether a shot is a 2-point field goal, or a 3-point field goal.
* `shot_distance:` distance to the basket(measured in feet).
* `x` and `y` refer to the court coordinates (measured in inches) where a shot occurred.

<file_sep>/GUI Part (Using PyQt)/README.md
### 2021.1.23说明
对该文件夹的部分说明：
* appMain2.py为拓展界面并打开界面的主文件
* demo1.py由demo1.ui生成，为GUI初始文件
* test_rc.py无任何实质意义，其仅使得demo1.py得以正常运行而不报错
* test.db为数据库文件，当前已存储部分实例数据（为真实环境测得），相关程序可调用数据库并进行数据分析、数据展示等
-------------------------------------------------------------------------------------------
### 2021.2.15说明
做出了以下改进：
* 新增两个功能按钮，尚未置入功能
* 数据显示方式作出改进，使得每个页面可以统计三种类型的数据（曲线、柱状、饼状），暂时均为概念图
* 暂时取消了注释，并删除了之前文件，设立了新的文件夹
<file_sep>/Hardware Part (using Arduino)/README.md
2021.2.15说明：
* 上传Arduino代码，使用Arduino IDE可以运行，实时获取Arduino数据
* 目前尚未进一步改进，仅能获得光照、湿度、温度、二氧化碳这四项目标数据（其余有机物数据非目标）
* 目前期望增加反馈功能

# 基于阿里云sdk c++ ddns
#### 介绍
本程序用于动态ip解析到域名的ddns程序，采用c++编写，可在不同架构处理器上工作。支持ipv4,ipv6解析。
如有任何问题或者建议可联系作者，qq:1261424813
#### 软件架构
软件架构说明:
本程序支持arm,arm64,x64架构，请根据设备自行修改CMakeLists.txt对应动态库链接目录编译
#### 安装教程
1. 编译之前请先打开CMakeLists.txt文件修改link_directories(${catkin_LIB_DIRS} arm64_lib)
对应系统的库文件目录，默认为arm64_lib，如果你系统是arm就输入arm_lib，x64就输入x64_lib。占时不支持windows。
2. 请使用命令cmake .构建编译环境，然后输入命令make即可编译
#### 使用说明
1. 首次使用ddns程序会在当前运行目录生成setting.dat配置文件，请根据提示操作并修改适合你自己的配置文件，你需要有阿里云的顶级域名和生成了AccessKeyID和AccessKeySecret
2. 程序参数:(如何使用:比如 ./ddns ipv4 即可返回本机ipv4信息)
2. ipv4 返回ipv4地址
3. ipv6 返回ipv6地址
4. d AccessKeyID AccessKeySecret 你的顶级域名 解析记录类型AAAA或者A 你的子域名
此参数为临时单次解析，可不需要设置配置文件，可配合crontab之内的配合使用
如: ./ddns d xxx xxx baidu.com AAAA www

<file_sep>To do:
Double check motor directions to ensure PID output - see DriveTrain:50
Start testing PID when drivetrain is done
Finish vision
Link vision distancing to flywheel motor input - Vision/Shooter subsystems, consider making a commandgroup to execute?

<file_sep># qr-platform-docker
Very simple docker container to run qr-platform.
It is an exercise for the user to figure out how they want to get redirects.json into the docker container. I am currently using an environment variable to pass in the JSON that I need. This isn't exactly scalable, but for now it will work. The ideal solution if scale is required would be to move to something like MongoDB and store all of the redirects there.

### Data Structures in JavaScript
#### The Array Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Array_data_structure):
*An Array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. The simplest type of data structure is a linear array, also called a one-dimensional array.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(1) | O(n) | O(1) | O(n) |
#### The Hash Table Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Hash_table):
*A Hash Table (Hash Map) is a data structure used to implement an associative array, a structure that can map keys to values. A Hash Table uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| - | O(1) | O(1) | O(1) |
#### The Set Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Set_(abstract_data_type)):
*A Set is an abstract data type (ADT) that can store certain values, wihout any particular order, with no repeated values. It is a computer implementation of the mathematical concept of a finite Set.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| - | O(n) | O(n) | O(n) |
#### The Singly Linked List Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Linked_list):
*A Singly Linked List is a linear collection of data elements, called nodes, pointing to the next node by means of a pointer. It is a data structure consisting of a group of nodes, which together represent a sequence. Under the simplest form, each node is composed of data and a reference (link) to the next node in the sequence.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(n) | O(n) | O(1) | O(1) |
#### The Doubly Linked List Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Doubly_linked_list):
*A Doubly Linked List is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links, that are references to the previous and next nodes in the sequence of nodes.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(n) | O(n) | O(1) | O(1) |
#### The Stack Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Stack_(abstract_data_type)):
*A Stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed. The order in which elements come off a Stack gives rise to its alternative name, **LIFO** (for **last in**, **first out**).*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(n) | O(n) | O(1) | O(1) |
#### The Queue Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Queue_(abstract_data_type)):
*A Queue is a particular kind of abstract data type or collection, in which the entities in the collection are kept in order and the principal operations are the addition of entities to the rear terminal position (enqueue), and removal of entities from the front terminal position (dequeue). This makes Queue a FIFO (**first in**, **first out**) data structure.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(n) | O(n) | O(1) | O(n) |
#### The Tree Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Tree_(data_structure)):
*A Tree is a widely used data structure that simulates a hierarchical tree structure, with a root value and subtrees of children with a parent node. A Tree data structure can be defined recursively as a collection of nodes (starting at a root node), where each node is a data structure consisting of a value, together with a list of references to nodes (the "children"), with the constraints that no reference is duplicated, and no children point to the root node.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(n) | O(n) | O(n) | O(n) |
## The Binary Search Tree Data Structure
From [Wikipedia](https://en.wikipedia.org/wiki/Binary_search_tree):
*A Binary Search Tree (BST) data structure is a rooted binary tree, whose internal nodes each store a key (and optionally, an associated value), and each have two distinguished sub-trees, commonly denoted left and right. The tree additionally satisfies the binary search tree property, which states that the key in each node must be greater than all keys stored in the left sub-tree, and smaller that all keys in the right sub-tree.*
Complexity:
| Access | Search | Insertion | Deletion |
| -------|--------|-----------|--------- |
| O(*log*(n)) | O(*log*(n)) | O(*log*(n)) | O(*log*(n)) |

Repo for CS50G assignments. These games are clones of other popular games, and were made for Harvard's CS50G (GD50) course.
## Course Link
https://courses.edx.org/courses/course-v1:HarvardX+CS50G+Games/course/
## Running All Assignments (Windows)
1. Download the .zip for the following repository: https://github.com/KurtYilmaz/cs50g-kurt-builds
2. Navigate though directories and double click the .exe file of any assignment you want to play.
## Building Assignments 1-7 (LÖVE, Windows, Mac, Linux)
1. [Download LÖVE, version 10.2 (I know it's outdated, the course uses libraries only compatible with 10.2)](https://bitbucket.org/rude/love/downloads/).
2. Install LÖVE.
3. Zip an assignment folder.
4. Rename the extension of the zipped folder from ".zip" to ".love".
5. Open the ".love" file.
## Building Assignments 8-11 (Unity, Windows, Mac, Linux)
1. [First, download Unity Hub](https://unity3d.com/get-unity/download).
2. Once installed, the sidebar on the left side should have an entry called "Installs".
3. Click the "Add" button on the link, direct to the official releases website, and download Unity 2018.1.0f2 for Unity Hub.
4. When Unity finishes installing, click on the sidebar entry called "Projects".
5. Click "Add" and navigate to the assignment folder.
6. Go to File->Build Settings, and select your target platform.
7. Click "Build," then make a folder called "Build".
8. Navigate to that folder and click on the executable.

#### 介绍
基于pytorch实现的 TextCNN 模型
#### 环境
python 3.6
pytorch 1.8.1
jieba 0.42.1
gensim 4.0.1
#### 数据集
分类包括：'财经', '房产', '教育', '科技', '军事', '汽车', '体育', '游戏', '娱乐'共9类
#### 数据预处理
1.将原始新闻文本文件按行打乱
2.使用jieba对所有新闻正文内容进行分词，得到词库
3.使用word2vec训练词库生成词向量模型
4.将原始新闻文本进行分词后，替换为词向量模型中的索引
分类,正文 -----> (分类id, [2,3,4,..词索引])
#### 测试结果
对新闻测试集进行测试
最终平均准确率为 91.171%
#### 项目结构
```
