Note: switching to 'v2.9.0-rc2'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:

# Migración
Para crear una migración nos movemos dentro de la carpeta del proyecto y ejecutamos el comando:
```php
php artisan make:model Task -m
```
Esto automáticamente crea un fichero en la carpeta `database/migrations/<timestap>_create_tasks_table.php`. Dentro de este fichero php se define la estructura que va a tomar la tabla tarea en la base de datos. La del ejemplo queda de la siguiente forma:
```php
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('tasks', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->boolean('completed')->default(false);
$table->timestamps();
});
}
/**
* Reverse the migrations.
*/
public function down(): void
{
Schema::dropIfExists('tasks');
}
};
```
### Explicación detallada
Este código es una migración de Laravel escrita utilizando la sintaxis de migraciones anónimas introducida en Laravel 8. Explicaré cada parte del código detalladamente:
1. **Importaciones**:
```php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
```
- `use Illuminate\Database\Migrations\Migration`: Esto importa la clase base `Migration` que proporciona Laravel para crear migraciones. Esta clase contiene los métodos necesarios para realizar y revertir migraciones.
- `use Illuminate\Database\Schema\Blueprint`: Esto importa la clase `Blueprint`, que es utilizada para definir la estructura de una tabla en la base de datos.
- `use Illuminate\Support\Facades\Schema`: Esto importa la fachada `Schema`, que proporciona una interfaz sencilla para interactuar con el sistema de migraciones.
2. **Creación de la Migración Anónima**:
```php
return new class extends Migration
{
// ...
};
```
Esto define una nueva clase anónima que hereda de la clase `Migration`. En este caso, se está creando una migración anónima. Esta es una característica introducida en Laravel 8 que permite definir una migración dentro de un solo archivo PHP sin necesidad de crear un archivo separado.
3. **Método `up()`**:
```php
public function up(): void
{
Schema::create('tasks', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->boolean('completed')->default(false);
$table->timestamps();
});
}
```
- `up()`: Este es el método que se ejecuta cuando se aplica la migración. En este caso, se está creando una nueva tabla llamada `tasks` utilizando el objeto `Schema`.
- `Schema::create('tasks', ...)`: Esto crea una nueva tabla llamada `tasks`. La función de callback toma un objeto `Blueprint` que te permite definir la estructura de la tabla.
- `$table->id()`: Este método agrega un campo de tipo clave primaria `id` a la tabla. Es comúnmente utilizado para identificar de forma única cada fila en la tabla.
- `$table->string('name')`: Este método agrega un campo de tipo cadena (`VARCHAR`) llamado `name`.
- `$table->boolean('completed')->default(false)`: Este método agrega un campo de tipo booleano llamado `completed` con un valor predeterminado de `false`.
- `$table->timestamps()`: Este método agrega dos campos `created_at` y `updated_at` que registran la fecha y hora de creación y actualización de cada registro en la tabla. Es una característica comúnmente utilizada para llevar un registro de la última vez que se modificó un registro.
4. **Método `down()`**:
```php
public function down(): void
{
Schema::dropIfExists('tasks');
}
```
- `down()`: Este es el método que se ejecuta cuando se revierte la migración. En este caso, se está eliminando la tabla `tasks` utilizando el objeto `Schema`.
- `Schema::dropIfExists('tasks')`: Esto elimina la tabla `tasks` si existe. Si la tabla no existe, no ocurre ningún error.
En resumen, este código define una migración que crea una nueva tabla llamada `tasks` con tres campos (`id`, `name` y `completed`) y dos timestamps (`created_at` y `updated_at`). Si alguna vez necesitas revertir esta migración, se eliminará la tabla `tasks` de la base de datos.
# Otros datos
### Blueprint Object
En el contexto de Laravel y las migraciones de bases de datos, un "Blueprint" es una clase que proporciona una interfaz orientada a objetos para definir la estructura de una tabla de base de datos.
La clase `Blueprint` se utiliza en las migraciones para especificar cómo se deben crear o modificar las tablas en la base de datos. Permite a los desarrolladores definir columnas, índices, claves foráneas y otras configuraciones de una manera programática y legible.
Algunas de las acciones comunes que puedes realizar con un `Blueprint` incluyen:
1. **Agregar Columnas**:
```php
$table->string('nombre');
```
Esto agrega una columna de tipo string llamada "nombre" a la tabla.
2. **Definir Claves Primarias**:
```php
$table->primary('id');
```
Esto define la columna "id" como clave primaria.
3. **Agregar Índices**:
```php
$table->index('email');
```
Esto agrega un índice a la columna "email" para mejorar la eficiencia de las consultas.
4. **Definir Claves Foráneas**:
```php
$table->foreign('user_id')->references('id')->on('users');
```
Esto define una clave foránea llamada "user_id" que referencia la columna "id" en la tabla "users".
5. **Definir Columnas de Timestamps**:
```php
$table->timestamps();
```
Esto agrega dos columnas llamadas "created_at" y "updated_at" que registrarán la fecha y hora de creación y actualización de cada registro.
6. **Definir Columnas de Soft Deletes**:
```php
$table->softDeletes();
```
Esto agrega una columna "deleted_at" para implementar la eliminación suave (soft delete) en la tabla.
El uso de un `Blueprint` hace que la definición de la estructura de la base de datos sea más legible y mantenible, especialmente en aplicaciones con bases de datos complejas o con múltiples desarrolladores que colaboran en el proyecto.
En resumen, un `Blueprint` en Laravel proporciona una forma programática y orientada a objetos de definir la estructura de una tabla de base de datos, lo que facilita la gestión y mantenimiento de la base de datos en el contexto de las migraciones.
### Definición formal de migraciones
En Laravel, una migración es una forma de interactuar con la base de datos utilizando código PHP en lugar de SQL directo. Proporciona una manera conveniente y controlada de modificar la estructura de la base de datos.
En términos simples, una migración en Laravel es un archivo de PHP que contiene instrucciones para crear o modificar tablas y columnas en tu base de datos. Cada migración es una clase PHP que utiliza el sistema de migración de Laravel.
Aquí hay una explicación más detallada:
1. **Definición**:
Una migración en Laravel se define como una clase PHP que hereda de la clase `Migration`. Esta clase tiene dos métodos importantes: `up` y `down`.
- `up`: Contiene las instrucciones para realizar la migración (por ejemplo, crear una nueva tabla, agregar una columna, etc.).
- `down`: Contiene las instrucciones para deshacer la migración (es decir, revertir los cambios realizados en `up`).
2. **Uso**:
Las migraciones se utilizan para mantener un control de la estructura de la base de datos a lo largo del tiempo, permitiendo a los desarrolladores trabajar de manera colaborativa y mantener un historial de los cambios en la base de datos.
Por ejemplo, supongamos que estás trabajando en un equipo y necesitas agregar una nueva columna a una tabla existente en la base de datos. En lugar de instrucciones SQL directas, puedes crear una migración que contenga las instrucciones para agregar la nueva columna. Luego, puedes compartir la migración con tu equipo, y cada miembro puede aplicarla a su propia base de datos de desarrollo.
Además, las migraciones facilitan la implementación y actualización de aplicaciones en diferentes entornos (como desarrollo, pruebas y producción), ya que puedes ejecutar las migraciones en cada entorno para asegurarte de que la base de datos esté configurada correctamente.
También, las migraciones permiten realizar un seguimiento de los cambios en el esquema de la base de datos a lo largo del tiempo, lo que facilita la reversión a versiones anteriores si es necesario.
En resumen, las migraciones en Laravel son una herramienta poderosa para gestionar la estructura de tu base de datos de una manera controlada y colaborativa, lo que facilita el desarrollo y mantenimiento de aplicaciones web. |

WELCOME TO DROIDS 1.20\par
\par
Our main goal is to try to visualize the impact of one of the longest time scale processes in the universe (i.e molecular evolution over 100s millions of years) on one of the shortest time scale processes (i.e. molecular motion over femtoseconds). To achieve this goal we use state-of-the-art biophysical simulations and graphics to design a gaming PC into a computational microscope that is capable seeing how mutations and other molecular events like binding, bending and bonding affect the functioning of proteins and nucleic acids. If you find this idea exciting, consider joining our coding efforts on GitHub. DROIDS-1.20 (Detecting Relative Outlier Impacts in molecular Dynamic Simulation) is a GUI-based pipeline that works with AMBER16, Chimera 1.11 and CPPTRAJ to analyze and visualize comparative protein dynamics on GPU accelerated Linux graphics workstations. DROIDS employs a statistical method (multiple test corrected KS tests on all backbone atoms of each amino acid) to detect significant changes in molecular dynamics simulated on two homologous PDB structures. Quantitative differences in atom fluctuation (i.e. calculated from vector trajectories) are displayed graphically and mapped onto movie images of the protein dynamics at the level of individual residues. P values indicating significant changes are also able to be similarly mapped. DROIDS is useful for examining how mutations, epigenetic changes, or binding interactions affect protein dynamics. DROIDS was produced by student effort at the Rochester Institute of Technology under the direction of Dr. Gregory A. Babbitt as a collaborative project between the Gosnell School of Life Sciences and the Biomedical Engineering Dept. Visit our lab website ({{\field{\*\fldinst{HYPERLINK https://people.rit.edu/gabsbi/ }}{\fldrslt{https://people.rit.edu/gabsbi/\ul0\cf0}}}}\f0\fs22 ) and download DROIDS 1.20 from Github at {{\field{\*\fldinst{HYPERLINK https://github.com/gbabbitt/DROIDS-1.0 }}{\fldrslt{https://github.com/gbabbitt/DROIDS-1.0\ul0\cf0}}}}\f0\fs22 . We will be posting video results periodically on our youtube channel at {{\field{\*\fldinst{HYPERLINK https://www.youtube.com/channel/UCJTBqGq01pBCMDQikn566Kw }}{\fldrslt{https://www.youtube.com/channel/UCJTBqGq01pBCMDQikn566Kw\ul0\cf0}}}}\f0\fs22 \par

INSTALLATION INSTRUCTIONS FOR DROIDS v1.20\par
\par
DROIDS is primarily a backend statistical analysis and visualization tool for comparative protein dynamics. Some very fine tools already exist for running GPU accelerated molecular dynamic (MD) simulation, vector trajectory analysis, and visualizing structures. Our philosophy is not to reinvent these tools but rather to create a user friendly GUI-based pipeline to enable these tools to be used in concert to statistically compare the stability of motion on the polypeptide backbone for two homologous structures.\par
\par
DROIDS requires a Linux OS with one or two high end CUDA enabled GPU graphics cards installed. As of 2018, our preferred GPU is the GeForce GTX 1080 card with roughly 2500 cores. With two of these installed, most single chain protein comparisons can be run in 12-48 hours. For very small structures, the program 'sander' in Ambertools17 can be called in place of pmemd.cuda and run without needing GPUs or the Amber16 license. To enable this, the user can rewrite the following lines below in MD_proteinReference.pl, MD_proteinQuery.pl, MD_proteinReference_dualGPU.pl, MD_proteinQuery_dualGPU.pl replacing "pmemd.cuda_SPFP" with "sander". Given the efficiency of modern GPU acceleration for MD, this is not generally recommended. \par
\par
\par
my $run_method = "pmemd1.cuda_SPFP"; # "sander" for CPU or "pmemd.cuda" for GPU;\par
my $method_ID = "pmemd1";\par
\par
\par
The primary software tools that must be installed on the Linux platform are\par
\par
Chimera 1.11 or later\par
Amber16\par
Ambertools17 (this will also give cpptraj)\par
CUDA 8.0\par
R-base language with the R packages 'ggplot2' and 'gridExtra'\par
Perl 5.12 or later\par
Python 2.7 or later (not python 3.0)\par
perl-tk\par
python-tk\par
python-gi\par
evince (a Linux pdf viewer)\par
\par
We highly recommend Linux Mint OS over Ubuntu as it provides more direct guidance via GUI for updating GPU graphics drivers when building the system. Generally, upon installation of the GPUs, the onboard graphics (on the motherboard) must be disabled via the BIOS or physical jumper and the monitor cable moved to the GPU card. In Linux Mint, the system will recommend driver updates upon rebooting via a pop-up GUI. In Ubuntu, the user usually needs to go to console (ctrl+alt+F1/F7), disable the x driver (e.g. sudo service lightdm stop/start), and install driver updates from the command line as root user. \par
\par
Once the GPU and graphics are properly configured, then the CUDA libraries must be installed (use CUDA 8.0 or higher)\par

= Device handling
This document describes how the IEC or IEEE488 device handling is done.
== Overview
The Commodore computers use a standard protocol on either the serial IEC (C64, VIC20, ...) or the
parallel IEEE488 (PET, CBM-II) busses. The protocol can handle devices on the bus using an address
between 0 and 30.
Typically these devices are used::
* 4-5 - printer and plotter
* 8-11 - disk drives and hard disks
Other devices known to exist for the IEC/IEEE488 bus are modems.
This emulator currently simulates disk drives only, using the host filesystem as source
for the files. It is planned to add a "true drive emulation" at least for the
parallel IEEE488 disk drives.
In the emulator, two ways are used to talk to the devices:
Traps::
In the ROM certain addresses are marked and the emulator traps out into
native code when the emulated CPU tries to execute code on these addresses.
This way the emulator can emulate the communication with the devices
in native code. For this, the traps are located e.g. when the CPU tries
to send bytes under ATN, and interprets the bytes appropriately to
forward the data to the correct emulated device.
This is mainly used for the serial IEC bus on the C64 emulation.
Direct::
In this mode the bus hardware lines are emulated as a shared bus between
the emulated CPU (e.g. a PET), and either virtual drives that listen
on the bus or true disk emulation drives that listen to the bus as well.
This does away with the traps, and is thus a much less intrusive emulation mode.
This is mainly used for the IEEE488 bus on the PET emulation.
== Code Structure
The following diagram shows how the code parts play together.
----
C64 emu traps -> c64/iec64.c -+-> devices.c -+-> vdrive.c
^ |
| +-> (other simulated devices, TODO)
PET PIA/VIA IO -> parallel.c -+
|
V
+-> (true emulated devices, TODO)
----
In the C64, c64/iec64.c traps the kernal, and forwards the requests
to the devices layer. This dispatches it to the virtual (simulated) disk drives
(or, at some point in the future, other devices).
The PET uses standard I/O from its PIA and VIA chips to handle IEEE488 lines
in the parallel.c code. This interprets the IEEE488 commands and hooks into the
devices code to forward when a virtual device is accessed.
At some point in the future, other true emulated devices may listen on the
same IEEE488 signal lines and handle them themselves. |

</section>
<p> </p>
<p>A class is a blueprint from which individual objects are created. These individual objects are the instances of the class. Each class defines one or more members, which are initialized to a given value when the class is instantiated. Data members are properties that allow each instance to have their own state, whereas member functions are properties that allow instances to have behavior. Inheritance allows classes to inherit state and behavior from an existing classes, known as the base class. Unlike languages like C++ and Java, JavaScript does not have native support for classical inheritance. Instead, it uses something called prototypal inheritance. As it turns out, it is possible to emulate classical inheritance using prototypal inheritance, but not without writing a significant amount of boilerplate code.</p>
<p>Classes in JavaScript are defined using constructor functions. Each constructor function has an associated object, known as its prototype, which is shared between all instances of that class. We will show how to define classes using constructors, and how to use prototypes to efficiently define member functions on each instance. Classical inheritance can be implemented in JavaScript using constructors and prototypes. We will show how to make inheritance work correctly with respect to constructors, prototypes, and the instanceof operator, and how to override methods in subclasses. The SDK uses a special constructor internally, known as <code>Class</code>, to create constructors that behave properly with respect to inheritance. The last section shows how to work with the <code>Class</code> constructor. It is possible to read this section on its own. However, to fully appreciate how <code>Class</code> works, and the problem it is supposed to solve, it is recommended that you read the entire article.</p>
<h2 id="Constructors">Constructors</h2>
<p>Before the ECMASCript 6 standard, a JavaScript class was defined by creating a constructor function for that class. To illustrate this, let's define a simple constructor for a class <code>Shape</code>:</p>
<pre><code>function Shape(x, y) {
this.x = x;
this.y = y;
}
</code></pre>
<p>We can now use this constructor to create instances of <code>Shape</code>:</p>
<pre><code>let shape = new Shape(2, 3);
shape instanceof Shape; // => true
shape.x; // => 2
shape.y; // => 3
</code></pre>
<p>The keyword new tells JavaScript that we are performing a constructor call. Constructor calls differ from ordinary function calls in that JavaScript automatically creates a new object and binds it to the keyword this for the duration of the call. Moreover, if the constructor does not return a value, the result of the call defaults to the value of this. Constructors are just ordinary functions, however, so it is perfectly legal to perform ordinary function calls on them. In fact, some people (including the Add-on SDK team) prefer to use constructors this way. However, since the value of this is undefined for ordinary function calls, we need to add some boilerplate code to convert them to constructor calls:</p>
<pre><code>function Shape(x, y) {
if (!this)
return new Shape(x, y);
this.x = x;
this.y = y;
}
</code></pre>
<h2 id="Prototypes">Prototypes</h2>
<p>Every object has an implicit property, known as its prototype. When JavaScript looks for a property, it first looks for it in the object itself. If it cannot find the property there, it looks for it in the object's prototype. If the property is found on the prototype, the lookup succeeds, and JavaScript pretends that it found the property on the original object. Every function has an explicit property, known as <code>prototype</code>. When a function is used in a constructor call, JavaScript makes the value of this property the prototype of the newly created object:</p>
<pre><code>let shape = Shape(2, 3);
Object.getPrototypeOf(shape) == Shape.prototype; // => true
</code></pre>
<p>All instances of a class have the same prototype. This makes the prototype the perfect place to define properties that are shared between instances of the class. To illustrate this, let's add a member function to the class <code>Shape</code>:</p>
<pre><code>Shape.prototype.draw = function () {
throw Error("not yet implemented");
}
let shape = Shape(2, 3);
Shape.draw(); // => Error: not yet implemented
</code></pre>
<h2 id="Inheritance_and_Constructors">Inheritance and Constructors</h2>
<p>Suppose we want to create a new class, <code>Circle</code>, and inherit it from <code>Shape</code>. Since every <code>Circle</code> is also a <code>Shape</code>, the constructor for <code>Shape</code> must be called every time we call the constructor for <code>Circle</code>. Since JavaScript does not have native support for inheritance, it doesn't do this automatically. Instead, we need to call the constructor for <code>Shape</code> explicitly. The resulting constructor looks as follows:</p>
<pre><code>function Circle(x, y, radius) {
if (!this)
return new Circle(x, y, radius);
Shape.call(this, x, y);
this.radius = radius;
}
</code></pre>
<p>Note that the constructor for <code>Shape</code> is called as an ordinary function, and reuses the object created for the constructor call to <code>Circle</code>. Had we used a constructor call instead, the constructor for <code>Shape</code> would have been applied to a different object than the constructor for <code>Circle</code>. We can now use the above constructor to create instances of the class <code>Circle</code>:</p>
<pre><code>let circle = Circle(2, 3, 5);
circle instanceof Circle; // => true
circle.x; // => 2
circle.y; // => 3
circle.radius; // => 5
</code></pre>
<h2 id="Inheritance_and_Prototypes">Inheritance and Prototypes</h2>
<p>There is a problem with the definition of <code>Circle</code> in the previous section that we have glossed over thus far. Consider the following:</p>
<pre><code>let circle = Circle(2, 3, 5);
circle.draw(); // => TypeError: circle.draw is not a function
</code></pre>
<p>This is not quite right. The method <code>draw</code> is defined on instances of <code>Shape</code>, so we definitely want it to be defined on instances of <code>Circle</code>. The problem is that <code>draw</code> is defined on the prototype of <code>Shape</code>, but not on the prototype of <code>Circle</code>. We could of course copy every property from the prototype of <code>Shape</code> over to the prototype of <code>Circle</code>, but this is needlessly inefficient. Instead, we use a clever trick, based on the observation that prototypes are ordinary objects. Since prototypes are objects, they have a prototype as well. We can thus override the prototype of <code>Circle</code> with an object which prototype is the prototype of <code>Shape</code>.</p>
<pre><code>Circle.prototype = Object.create(Shape.prototype);
</code></pre>
<p>Now when JavaScript looks for the method draw on an instance of Circle, it first looks for it on the object itself. When it cannot find the property there, it looks for it on the prototype of <code>Circle</code>. When it cannot find the property there either, it looks for it on <code>Shape</code>, at which point the lookup succeeds. The resulting behavior is what we were aiming for.</p>
<h2 id="Inheritance_and_Instanceof">Inheritance and Instanceof</h2>
<p>The single line of code we added in the previous section solved the problem with prototypes, but introduced a new problem with the <strong>instanceof</strong> operator. Consider the following:</p>
<pre><code>let circle = Circle(2, 3, 5);
circle instanceof Shape; // => false
</code></pre>
<p>Since instances of <code>Circle</code> inherit from <code>Shape</code>, we definitely want the result of this expression to be true. To understand why it is not, we need to understand how <strong>instanceof</strong> works. Every prototype has a <code>constructor</code> property, which is a reference to the constructor for objects with this prototype. In other words:</p>
<pre><code>Circle.prototype.constructor == Circle // => true
</code></pre>
<p>The <strong>instanceof</strong> operator compares the <code>constructor</code> property of the prototype of the left hand side with that of the right hand side, and returns true if they are equal. Otherwise, it repeats the comparison for the prototype of the right hand side, and so on, until either it returns <strong>true</strong>, or the prototype becomes <strong>null</strong>, in which case it returns <strong>false</strong>. The problem is that when we overrode the prototype of <code>Circle</code> with an object whose prototype is the prototype of <code>Shape</code>, we didn't correctly set its <code>constructor</code> property. This property is set automatically for the <code>prototype</code> property of a constructor, but not for objects created with <code>Object.create</code>. The <code>constructor</code> property is supposed to be non-configurable, non-enumberable, and non-writable, so the correct way to define it is as follows:</p>
<pre><code>Circle.prototype = Object.create(Shape.prototype, {
constructor: {
value: Circle
}
});
</code></pre>
<h2 id="Overriding_Methods">Overriding Methods</h2>
<p>As a final example, we show how to override the stub implementation of the method <code>draw</code> in <code>Shape</code> with a more specialized one in <code>Circle</code>. Recall that JavaScript returns the first property it finds when walking the prototype chain of an object from the bottom up. Consequently, overriding a method is as simple as providing a new definition on the prototype of the subclass:</p>
<pre><code>Circle.prototype.draw = function (ctx) {
ctx.beginPath();
ctx.arc(this.x, this.y, this.radius,
0, 2 * Math.PI, false);
ctx.fill();
};
</code></pre>
<p>With this definition in place, we get:</p>
<pre><code>let shape = Shape(2, 3);
shape.draw(); // Error: not yet implemented
let circle = Circle(2, 3, 5);
circle.draw(); // TypeError: ctx is not defined
</code></pre>
<p>which is the behavior we were aiming for.</p>
<h2 id="Classes_in_the_Add-on_SDK">Classes in the Add-on SDK</h2>
<p>We have shown how to emulate classical inheritance in JavaScript using constructors and prototypes. However, as we have seen, this takes a significant amount of boilerplate code. The Add-on SDK team consists of highly trained professionals, but they are also lazy: that is why the SDK contains a helper function that handles this boilerplate code for us. It is defined in the module “core/heritage”:</p>
<pre><code>const { Class } = require('sdk/core/heritage');
</code></pre>
<p>The function <code>Class</code> is a meta-constructor: it creates constructors that behave properly with respect to inheritance. It takes a single argument, which is an object which properties will be defined on the prototype of the resulting constructor. The semantics of <code>Class</code> are based on what we've learned earlier. For instance, to define a constructor for a class <code>Shape</code> in terms of <code>Class</code>, we can write:</p>
<pre><code>let Shape = Class({
initialize: function (x, y) {
this.x = x;
this.y = y;
},
draw: function () {
throw new Error("not yet implemented");
}
});
</code></pre>
<p>The property <code>initialize</code> is special. When it is present, the call to the constructor is forwarded to it, as are any arguments passed to it (including the this object). In effect, initialize specifies the body of the constructor. Note that the constructors created with <code>Class</code> automatically check whether they are called as constructors, so an explicit check is no longer necessary.</p>
<p>Another special property is <code>extends</code>. It specifies the base class from which this class inherits, if any. <code>Class</code> uses this information to automatically set up the prototype chain of the constructor. If the extends property is omitted, <code>Class</code> itself is used as the base class:</p>
<pre><code>var shape = new Shape(2, 3);
shape instanceof Shape; // => true
shape instanceof Class; // => true
</code></pre>
<p>To illustrate the use of the <code>extends</code> property, let's redefine the constructor for the class <code>Circle</code> in terms of <code>Class</code>:</p>
<pre><code>var Circle = Class({
extends: Shape,
initialize: function(x, y, radius) {
Shape.prototype.initialize.call(this, x, y);
this.radius = radius;
},
draw: function (<code>context</code>) {
context.beginPath();
context.arc(this.x, this.y, this.radius,
0, 2 * Math.PI, false);
context.fill();
}
});
</code></pre>
<p>Unlike the definition of <code>Circle</code> in the previous section, we no longer have to override its prototype, or set its <code>constructor</code> property. This is all handled automatically. On the other hand, the call to the constructor for <code>Shape</code> still has to be made explicitly. This is done by forwarding to the initialize method of the prototype of the base class. Note that this is always safe, even if there is no <code>initialize</code> method defined on the base class: in that case the call is forwarded to a stub implementation defined on <code>Class</code> itself.</p>
<p>The last special property we will look into is <code>implements</code>. It specifies a list of objects, which properties are to be copied to the prototype of the constructor. Note that only properties defined on the object itself are copied: properties defined on one of its prototypes are not. This allows objects to inherit from more than one class. It is not true multiple inheritance, however: no constructors are called for objects inherited via <code>implements</code>, and <strong>instanceof</strong> only works correctly for classes inherited via <code>extends</code>.</p> |

# react/no-set-state-in-component-did-update
## Rule category
Suspicious.
## What it does
Disallows calling `this.setState` in `componentDidUpdate` outside of functions, such as callbacks.
## Why is this bad?
Updating the state after a component mount will trigger a second render() call and can lead to property/layout thrashing.
## Examples
### Failing
```tsx
import React from "react";
class MyComponent extends React.Component {
componentDidUpdate() {
this.setState({ name: "John" });
}
render() {
return <div>Hello {this.state.name}</div>;
}
}
```
### Passing
```tsx
import React from "react";
class MyComponent extends React.Component {
componentDidUpdate() {
this.onMount(function callback(newName) {
this.setState({
name: newName,
});
});
}
render() {
return <div>Hello {this.state.name}</div>;
}
}

# Projeto e Modelagem de Bancos de Dados - 2024.1 - turma A
## Projeto AV2
### Equipe: Arthur Wolmer e Diego Peter
O processo de desenvolvimento da aplicação cobriu os pontos de 1. a 4. aproximadamente em sequência, com a exploração das tecnologias correndo em paralelo.
# 1. **Análise de requisitos**
Minimundo (criado pela equipe):
Um **armazém de produtos de informática** precisa controlar seu e**stoque ao longo do tempo e gerenciar aspectos logísticos** relacionados ao fluxo de mercadorias.
O que o armazém armazena são itens, que representam uma "instância" de um produto, fornecido por um fornecedor. É possível que o mesmo produto seja fornecido por mais de um fornecedor, como no caso de GPUs de marcas distintas com o mesmo chipset, ou um mesmo periférico fornecido por importadores distintos. Cada item presente no banco de dados precisa ter um funcionário associado, responsável pelo cadastro, e um timestamp (data e hora) relativo ao cadastro.
Produtos representam um modelo de produto e tem nome, categoria e uma descrição (opcional). Cada produto pode ou não ser frágil. Um produto deve pertencer a uma ou mais categorias.
Categorias possuem nome e descrição (opcional).
Fornecedores têm cnpj, nome e dados de contato (telefone e e-mail).
A perda de itens do estoque relaciona o item perdido, funcionário responsável pela identificação e um timestamp (data e hora) para a perda. Só podem ser perdidos itens previamente cadastrados no banco e que não foram expedidos em algum pedido (vendidos). Além disso, deve ser registrado um motivo para a perda, o qual só pode assumir alguns valores distintos: extravio, dano de acondicionamento (armazém), problema de fabricação ou transporte (fornecedor).
Por fim, um ou mais itens cadastrados podem ser expedidos como parte de um pedido (venda). Deve ser relacionado o funcionário responsável, os itens envolvidos (entre os cadastrados e não perdidos), um timestamp (data e hora) e o cliente que realizou o pedido.
Funcionários têm cpf, nome e dados de contato (telefone e email). Podem ser gerentes ou não. Todo funcionário gerente pode ser supervisor de outros funcionários e todo funcionário não-gerente deve ter um outro funcionário, gerente, como supervisor.
Clientes têm nome, dados de contato (telefone e e-mail) e podem ser pessoas físicas ou pessoas jurídicas; pessoas físicas têm cpf e pessoas jurídicas, cnpj.
Cada cliente pode ter um número arbitrário de endereços de entrega. Endereços de entrega são compostos pelo nome do destinatário e endereço (com estado, municipio, CEP, logradouro, numero e complemento).
Cada pedido expedido, além de cliente e funcionário, também está relacionado a um endereço de entrega, uma transportadora e possui código de rastreamento.
Transportadoras têm cpnj, nome, dados de contato (telefone e e-mail).

# 5. Desenvolvimento da aplicação
1. Front-end
- Framework: React com Vite (https://vitejs.dev/)
- Shadcn para componentes de UI (https://ui.shadcn.com/) e TanStack para roteamento, queries, tabelas e forms (https://tanstack.com/)
2. Back-end
- Framework: SpringBoot (Maven).
- Sem uso de ORM, mas preservando arquitetura do Springboot (controllers-services-repositories), classes JDBC para acesso direto ao banco de dados com queries SQL escritas à mão.
3. Banco de dados:
- Docker Compose para orquestrar o containers do banco de dados (inclusive execução automática do script de inicialização)
- Triggers para garantir integridade do banco dentro das regras de negócio e impedir a invalidação da funcionalidade do histórico de estoque
- Procedures e views para extração de relatórios |

<p>物體碰撞前後總動能不變稱為彈性碰撞（Elastic collision），在維基百科〈<a href="https://en.wikipedia.org/wiki/Elastic_collision">Elastic collision</a>〉中可以查詢到，二維的彈性碰撞在位置及速度以向量表示時，公式會如下，其中角括號表示向量內積：</p>
<p><div class="pure-g"><div class="pure-u-1"><img class="pure-img-responsive" src="images/Collision-1.JPG" alt="彈性碰撞" /></div></div></p>
<p>根據這個公式，可以在 <code>Body</code> 定義 <code>collideWith</code> 方法：</p>
<pre class="prettyprint"><code lang="javascript">class Body {
constructor(coordinate, velocity, mass = 1) {
this.coordinate = coordinate;
this.velocity = velocity;
this.mass = mass;
}
...
collideWith(body) {
const d = sub(this.coordinate, body.coordinate);
const m = body.mass / (this.mass + body.mass);
this.velocity = sub(
this.velocity,
d.mult(
2 * m / pow(d.mag(), 2) * p5.Vector.dot(
sub(this.velocity, body.velocity),
sub(this.coordinate, body.coordinate)
)
)
);
}
...
}
</code></pre>
<p>問題在於如何判斷何時發生碰撞？直覺的想法是兩個圓的圓心距離等於半徑時，可惜的是，如同〈<a href="Bounce.html">邊界反彈</a>〉談過的，因為影格在時間上是不連續的，真正的碰撞時間可能發生在影格之間，也就是兩個圓的圓心距離等於半徑時可能發生在影格之間，這你是要怎麼呼叫 <code>collideWith</code> 呢？</p>
<p>那就在下個影格時，看看兩個圓的圓心距離是否小於等於半徑呢？例如：</p>

<p>乍看是還行，不過程式運行一段時間後，可能會發生兩個圓碰撞後糾纏在一起的情況，這是因為兩個圓其實是彼此穿透，然後才碰撞交換動能，在接下來的影格以碰撞後的速度移動後，移動距離不夠，造成兩個圓仍然彼此穿透，這時又判斷是該發生碰撞了…結果就一直黏在一起了…XD</p>
<p>解決的方式其實類似〈<a href="Bounce.html">邊界反彈</a>〉的出發點，穿透後必須自行修正座標，然而顯然地，這邊不能單純地用反射的方式來計算，怎麼辦呢？</p>
<p>這邊的做法是，若判斷兩個圓的圓心距離小於等於半徑和時，表示直接繪製的話，會是穿透的狀態，這時計算上一影格時的位置：</p>
<p><div class="pure-g"><div class="pure-u-1"><img class="pure-img-responsive" src="images/Collision-2.JPG" alt="彈性碰撞" /></div></div></p>
<p>接著計算這時圓心間的距離，兩個圓的相對速度大小，求得接下來還要多久會發生碰撞，以程式碼表示的話會是：</p>
<pre class="prettyprint"><code lang="javascript">// sub 是 p5.Vector.sub 的封裝
function timeBeforeCollision(b1, b2, d, tolerant) {
// 退回
const preC1 = sub(b1.coordinate, b1.velocity);
const preC2 = sub(b2.coordinate, b2.velocity);
// 相對速度
const rv = sub(b1.velocity, b2.velocity).mag();
// 還要多久碰撞
return (sub(preC1, preC2).mag() + tolerant - d) / rv;
}
</code></pre>
<p>因為浮點數計算會有誤差，這會導致糾纏還是會發生一下，這部份可以用 <code>tolerant</code> 設定容許的誤差來克服。</p>
<p>若求得的時間差是 <code>t</code>，接下來就可以求得兩個圓發生碰撞時的圓心位置：</p>
<pre class="prettyprint"><code lang="javascript">function coordinateAfterTime(b, t) {
return add(b.coordinate, p5.Vector.mult(b.velocity, t));
}
function collisionCoordinate(b, t) {
const preC = coordinateAfterTime(b, -1)
return add(preC, p5.Vector.mult(b.velocity, t));
}
</code></pre>
<p>將圓移動至求得的位置後，就可以呼叫 <code>collideWith</code> 進行動能交換了，接下來離下個影格的時間還剩 <code>1 - t</code>（在我們模擬的世界中，影格間的時間就是一個時間單位），利用這段時間，以及動能交換後的速度來移動，就會是碰撞後，在下個影格時該有的位置：</p>
<pre class="prettyprint"><code lang="javascript">// 用剩餘時間移動
c1.body.coordinate = coordinateAfterTime(b1, 1 - t);
c2.body.coordinate = coordinateAfterTime(b2, 1 - t);
</code></pre>
<p>記得！碰撞的時間發生在兩個影格間時，你是看不到兩個圓接觸的畫面的，只會看到碰撞後下個影格時該在的位置，底下是完整的程式示範：</p>

<p>來點有趣的事好了，如果有個圓是被釘死而無法撼動的話會怎樣呢？如果自身就是無法撼動的圓，就不用動態交換，也就是 <code>collideWith</code> 直接 <code>return</code>，如果碰撞的對象無法撼動，可以將對方的質量當成無限大來看，也就是碰撞公式的 <code>m2/(m1 + m2)</code>，也就是 <code>1 / (m1/m2 + 1)</code> 中的 <code>m2</code> 會是無限大，這時結果就是 1。</p>
<pre class="prettyprint"><code lang="javascript">class Body {
constructor(coordinate, velocity, mass = 1, shakable = true) {
this.coordinate = coordinate;
this.velocity = velocity;
this.mass = mass;
this.shakable = shakable;

…
collideWith(body) {

<p>一個有趣的結果是，如果圓無法撼動，它又有速度會如何？這像是有個被釘在移動帶的圓，可以移動，但其他圓無法撼動它，在其他圓撞上無法撼動的圓時，無法撼動的圓基於自身速度與質量的動能，會附加至撞上的圓，這些圓自身的動能，又會被反射回自身，結果就會越來越快。</p>
<p>這並不是奇怪的結果，被釘在移動帶的圓，就相當於移動帶在提供穩定的動能，其他圓撞上後會吸收這些動能，結果就會越來越快。</p>
<p>如果你想要一個會移動的圓，又不想要撞上它的圓越來越快，就是讓該圓無法撼動，速度為 0，每次的影格都直接改變該圓座標就可以了。</p>
