1,664,705 | Object Oriented Programming In Javascript: A comprehensive guide | What is object-oriented programming? Object-oriented programming is a programming paradigm... | 0 | 2023-11-13T12:37:02 | https://dev.to/snevy1/object-oriented-programming-in-javascript-a-comprehensive-guide-402h | webdev, javascript, programming, beginners |
## What is object-oriented programming?
Object-oriented programming is a programming paradigm or concept in which we wrap our data and functionality into objects
The world is made up of objects, i.e.person, tree, car,school etc.
When we think and write code in terms of objects it is easier to understand, to reuse and to scale our code.
Object Oriented Programming is different from functional programming in that the latter emphasizes on logic that manipulates objects rather than the object itself while the former focuses on objects and adds logic to it.
A common way of object oriented programming is to create objects, add functionality and data to it. Then find a way in which these objects, their subclass objects and sibling objects relate.
For example, an animal is an object, an animal can eat, can move and can sleep.
We create an animal object. We add functionality to this object.Some of the functions are eat, move and sleep.
Notice that all animals can eat, move and sleep but not all can speak.
A person is an animal that can speak. By itself a person is an object and relates to the animal object because is a subclass of animal but is special because it can speak.
In OOP we find a way to relate the animal object and a person object.
That is to say, we relate a parent object(class) to its children(subclass) or a parent to another parent.
That is quite a mouthful introduction. Let's now focus on OOP in javascript
In javascript, data can be numbers, boolean, string, objects, arrays,functions etc
Functions inside of an object are called methods.
Actually, the term **method** is just a way to know that the function we are talking about is inside an object.
In javascript there are three main ways to create an object
Let us create a player object and add data and some functionality to it
The common way is using object literal. In this method we create an object then add data and functions immediately.
```Javascript
//First way
const player = {
name: "John",
score: 6,
increment: function () {
player.score++;
},
};
// console.log(player)
```
When we log player:
We can also create an object by first creating an empty object then add data and functions later
In this way, javascript first asks, Is there a variable called name? if yes, it reassigns its value.If no, it creates a new variable with value and adds it to the object.
```Javascript
//Second way
const player = {}; //Empty object
player.name = "John";
player.score = 6;
player.increment = function () {
player.score++;
};
//console.log(player)
```
When we log player, you will notice it looks similar to way1:
We can also create an empty object by using inbuilt method in javascript(**Object.create(null)**) then add data and functions.
So what the hell is this **Object.create(null)**? We shall answer this question later.
Notice that this third way looks suspiciously similar to the second way above except for the "Object.create()" thing.
```Javascript
//Third method
const player = Object.create(null);
player.name = "John";
player.score = 6;
player.increment = function () {
player.score++;
};
//console.log(player)
```
Let's log player once more:
Why would we use the third way when the first 2 ways can just do fine? We will answer this question after a few more explanations. Stay tuned.
## Functions in Javascript
Functions enable us to implement logic i.e manipulate data, create data, store data etc.
Imagine you are creating a game that requres more than 100 players. Creating an object for each of the player manually is tiresome.
This is where we can use a function that when invoked creates an object for us automatically.The only thing we need to do is to give it a name of the player and a score.
Let's us create a function called **playerCreator**. Read the comments in the code to understand how javascript runs it.Follow the numbers to understand which code is executed first.
```Javascript
// 1. playerCreator in instantiated and assigned a function definition. Javascript leaves it that way because it is not yet invoked!
function playerCreator(name, score){
//3. Javascript pairs the parameters(name and score) with arguments("John" and 6)
// By this time name has a value of John and score has a value of 6. i.e name: "John", score: 6.
// 4. Create a new empty object
const newObject = {}; //Empty object
// 5. Add property key values to the object
newObject.name = name;
//To the left before (=) we are creating a property(key) called name
//To the right we are giving that property a value that is stored in a variable called name.
newObject.score = score;
newObject.increment = function () {
newObject.score++;
};
/* The final player object looks this way :
newObject = {
name = "John",
score = 6
increment = function(){}
} */
// 6. //We return the newObject.This is the object that playerCreator function has made for us!
return newObject;
}
// 2. playerCreator is invoked
// 7. Assign the value returned by playerCreator() after its ivokation to a variable named player.
const player = playerCreator("John", 6)
const player2 = playerCreator("Doe", 8)
```
The above code is great... we have solved one problem of not creating every new object by ourselves but you notice that every time an object is created the increment function is also created.
If we log the value of player and player2 we notice that they both have the increment function:
There is nothing special about increment function. It does the same thing for all objects. It would be nice if we can have such a function in just one place from where every object can access it. This saves memory and improves perfomance.
It turns out that we can actually implement this by using **Object.Create()** introduced earlier.
According to MDN: `The Object.create() static method creates a new object, using an existing object as the prototype of the newly created object.`
Did you understand what that statement mean? If not don't feel bad, soon it will make sense.
... Creates a new object - This seems like what we initially did by creating an empty object in the playerCreator function right? But this time this method does it for us
... Using - For a function or a method to use something you must give it that thing right? We give Object.create something by passing it in the bracket i.e Object.create(somethingthat we give).
... an existing object - Where is this existing object? It must be somewhere right? It turns out that maybe there isn't and therefore the method will use **null** as a parameter or If there is an existing object it will use it i.e Object.create(an existing object).
...as the prototype - What is a prototype? Every object in javascript has a its own property called a prototype. What does this even mean?
First, remember that an object has property: key value pairs. These properties and keys can be created or are inbuilt.
These properties can be a **name** with a **value** of a string, an **object** with a **value** of an **array** or an **object** with a value of an **object** etc
Prototype - This is an inbuilt property of an object in javascript which by itself is an object and has its value as an **object**
Consider the code below:
```javascript
object1 = {
name: "John",
prototype: {
//I am an object, a value of prototype
someFunc: function () {
//do something...
},
},
};
```
Since a prototype is an object, and is a property of **object1**, object1 can access prototype's data i.e Object1.prototype.someFunc
..of the newly created object
In short, in our case Object.create(someObject or null), first creates a new object (Object1) then uses Object1's property(prototype property) to assign data of **someObject** to prototype. The code snippet above becomes:
```Javascript
object1 = {
name: "John",
prototype: {
//someObject's data
someFunc: function(){
}
}
}
```
To summarize, we can use Object.create() to pass in an object that has all functions and data that are common to all players and so each player
will have access to this object's data because there is a bond created between the prototype(the passed in object) and the newly created object.
Wow! That is alot. Consider taking a break before continuing.
In this section, let's start by creating an object that stores all of the common functions of players
```javascript
const playerFunctionsStore = {
increment: function () {
this.score + 1;
//Whenever you use "this" keyword inside of a method, 'this" refers to the object on which the method was called on
// In this case, the object on which increment was called on is player, so javascript replaces "this" with player
// hence this.score++ will be player.score++
},
login: function () {
console.log("logged in");
},
};
```
let's create a function that will create objects for us.
The new objects will have playerFunctionsStore's object data assigned to their prototype property(This is done automatically by Object.create())
The bond between the newObject and its prototype is fomarlly called \_ _ proto_ \_.
To understand more read the comments in the code
```Javascript
function playerCreator(name, score){
//Object.create creates a new empty object using an existing object(playerFunctionsStore) as prototype of the newly created object
let newObject = Object.create(playerFunctionsStore)
//In addition to Object.create giving us a new object, it also creates a bond(_ _proto_ _) between the newly created object, newObjectand its prototype that we passed into the brackets.
//By default, an object inherits functions(method) and data from its prototype thus because playerFunctionsStore is a prototype of newObject, newObject can access functions such as login and increment that are stored in playerFunctionsStore
//To access properties of its prototype, newObject uses the bond/link officially called _ _proto_ _
// _ _proto_ _ is a property of objects including newObject that javascript uses to look for data in the inheritance chain
newObject.name = name
newObject.score = score
return newObject
}
let player = playerCreator("John", 9)
let player2 = playerCreator("Doe", 8)
// The score has increased by one
```
You notice from the image below that increment and login function are not on the player and player2 objects.
To see these functions we expand on the \_ _proto_ \_:
This is a great solution in that it saves memory however, in modern javascript we don't want to leave our information in a global store.
What if someone accidentally deletes the store? Then all of our information will be lost.
It would be nice if there is no global store for functions but rather the store is an object inside of a function. We will address this issue in the next section.
Also, what if there is a way in in which we don't need to use or write the Object.create() to create objects but this can be done for us automatically?
It turns out there is: The **new** keyword **:)**
In the next section of this article we will dive into the use of the new keyword
### The **new** keyword
let's start by recreating the objects and functions we have used previously.
The **new** keyword before a function invokation does four things:
- Automatically create a new object
- Assign this keyword to the newObject hence this.name in the playerCreator() will be newObject.name during execution
- Javascript automatically creates \_ _ proto _ \_ and assigns it to the prototype property of playerCreator (the function that is to the right of the new keyword)
- Automatically returns the newObject out of that function
Please follow the numbers to understand the sequence in which javascript is executing the code. Also read the comments.
```javascript
// 1. Javascript instantiates a variable called playerCreator and assigns a function definition as its value
function playerCreator(name, score) {
// 7. Javascript by using the new keyword assigns "this" a value of newly created object
this.name = name;
this.score = score;
// 8. Returns a newObject automatically. No manuall writing of return
}
// 2. Javascript will look for playerCreator then look for its key called prototype
// 3. Then look if the prototype key has increment function if not it will create the function and store it in the prototype key(property).
playerCreator.prototype.increment = function () {
this.score++;
};
// 4. Javascript will do the same as in 2 and 3
playerCreator.prototype.login = function () {
this.login = false;
};
// 5. Javascript will invoke the playerCreator function
const player = new playerCreator("Jose", 8);
console.log(player);
```
We realize that we get the same result as we would use Object.create()
The downside of this method is that we have to Capitalize the first letter of the creatorfunction so we know it requires the new keyword
Because of this the class syntax was introduced.
**The class - Syntactic sugar**
Introduced in 2015
It is cleaner but no perfomance benefit
Majorly used in modern frameworks such as React.
The main diffence in syntax is:
- All the shared methods are put together in the constructor so there is no playerCreator.prototype.someFunction
- the constructor replaces the this.name, this.score and removes the parameters from being passed directly in the playerCreator function
Look at the images below to understand the difference. The replaced parts have corresponding highlighted colors
This has been a long article! I think it is worth it though.
In the next article that I will be rolling out soon, we will discuss more on classes, and introduce the Factory functions

Introduction
Graphs are everywhere, from social networks and recommendation systems to transportation networks and molecular structures. Analyzing and making predictions on graph data has become increasingly important in various domains. To tackle these challenges, one must understand how to train and work with graph datasets effectively. In this blog, we'll explore the key concepts and strategies for training graph datasets, providing you with a roadmap to harness the power of graph-based machine learning.
Understanding Graph Data
Before diving into training graph datasets, let's grasp the fundamental concepts:
Nodes: Nodes are the entities in a graph, representing individual data points. In a social network, nodes could be users, while in a transportation network, nodes could be cities or intersections.
Edges: Edges are connections between nodes that represent relationships or interactions. In a social network, edges could signify friendships, while in a transportation network, edges could represent roads or pathways.
Graph Structure: The arrangement of nodes and edges defines the structure of a graph. Graphs can be directed (edges have a specific direction) or undirected (edges are bidirectional), and they can have various topologies, such as trees, cycles, or random structures.
Graph Features: Graphs can include node features (attributes associated with each node) and edge features (attributes associated with each edge). These features provide valuable information for machine learning tasks.
Training Strategies for Graph Datasets
Now that we have a foundational understanding of graph data, let's explore how to train models effectively:
Data Preprocessing:
Data Cleaning: Ensure that your graph data is clean and free of errors or inconsistencies.
Feature Engineering: Extract meaningful features from nodes and edges to represent the graph more effectively.
Node Embeddings: Convert nodes and their features into numerical representations using techniques like node embeddings (e.g., GraphSAGE, node2vec).
Data Splitting:
Train-Validation-Test Split: Divide your graph dataset into three parts: a training set, a validation set, and a test set to assess model performance.
Ensure Data Integrity: Be mindful of preserving the integrity of the graph structure when splitting the data.
Model Selection:
Graph Neural Networks (GNNs): GNNs are specialized models designed for graph data. They leverage node and edge features to make predictions, and popular GNN architectures include Graph Convolutional Networks (GCNs) and Graph Attention Networks (GATs).
Training:
Loss Functions: Choose appropriate loss functions based on your task, such as binary cross-entropy for classification or mean squared error for regression.
Optimization: Utilize optimization techniques like stochastic gradient descent (SGD) or its variants (e.g., Adam) to train your models.
Regularization: Prevent overfitting by applying regularization techniques like dropout or graph-based regularization.
Evaluation:
Metrics: Select relevant evaluation metrics for your specific task, such as accuracy, F1 score, or mean squared error.
Cross-Validation: Consider using k-fold cross-validation to obtain a more robust assessment of model performance.
Hyperparameter Tuning:
Grid Search or Random Search: Experiment with different hyperparameter combinations to fine-tune your model's performance.
Bayesian Optimization: Utilize Bayesian optimization algorithms to efficiently search for optimal hyperparameters.
Interpretability:
Explainable AI: Consider techniques to interpret and visualize the predictions of your graph models, making them more interpretable and trustworthy.
Challenges in Training Graph Datasets
Training models on graph data comes with its own set of challenges:
Scalability: Graph datasets can be massive, requiring scalable algorithms and infrastructure.
Graph Structure: Maintaining the integrity of the graph structure during preprocessing and training is essential.
Data Imbalance: Address class imbalance issues when working with graph classification tasks.
Graph Noisy Labels: Be aware of the potential for noisy labels in graph data and employ robust learning techniques.
Conclusion
Training graph datasets is a crucial skill in the realm of modern machine learning and data science. With an understanding of graph structures, data preprocessing, model selection, and evaluation strategies, you can embark on exciting journeys of analyzing and making predictions on complex graph data. Whether you're interested in social network analysis, recommendation systems, or any other graph-related task, mastering the art of training graph datasets will empower you to navigate the intricate world of interconnected data successfully.

In today's technology-driven world, operating systems (OS) play an indispensable role, orchestrating the seamless interaction between hardware and software, enabling us to harness the power of our computers. But have you ever wondered about the intricacies of these digital maestros? How do they manage resources, boot up systems, and facilitate process execution? Let's embark on a journey to unveil the fascinating world of operating systems.
## The Heart of the Digital Realm: Unveiling the Kernel
At the core of every operating system lies the kernel, the maestro conducting the symphony of hardware and software. It's the first component to load during system initialization, establishing a direct connection with the hardware, managing memory allocation, and handling critical tasks like device drivers and system calls.
### Kernel Architectures: A Tale of Monolithic, Micro, Hybrid, and Exo
The world of kernels is diverse, each architecture offering unique advantages and challenges. Monolithic kernels, like Linux and Unix, provide exceptional performance due to their tightly coupled design, but their large size can pose stability issues. Microkernels, on the other hand, prioritize stability by relocating non-essential services to user space, but this can lead to performance overhead.
Hybrid kernels strike a balance, incorporating elements of both monolithic and microkernels, aiming to achieve both stability and performance. Exo kernels, the newest entrants, push critical kernel functions into hardware, promising even greater efficiency.
## The Bridge Between Applications and the Kernel: The API's Role
Applications cannot directly interact with the kernel's raw power; they must rely on application programming interfaces (APIs) intermediaries. These APIs provide a standardized set of functions that allow applications to request services from the kernel, such as file management, input/output operations, and memory allocation.
## System Calls: The Kernel's Gatekeepers
When an application needs to access kernel-protected resources, it makes a system call, a special request that temporarily grants the application kernel-level privileges. System calls are implemented in C and are the sole mechanism for user programs to interact with the kernel.
## The Boot Process: From Power On to User Mode
The journey of an operating system begins with the boot process, a sequence of events that brings the system to life. Upon power on, the CPU initializes itself and loads the BIOS (Basic Input/Output System) firmware stored in the BIOS chip. The BIOS performs hardware tests, loads configuration settings, and hands over control to the bootloader.
The bootloader, in turn, locates the operating system files and loads the kernel into memory. The kernel then initializes essential system components, such as device drivers and memory management, and sets up the user environment. Finally, the kernel launches the initial user process, typically a login shell, granting the user control over the system.
## 32-Bit vs. 64-Bit OS: A Battle of Addressable Memory
Operating systems come in two flavours: 32-bit and 64-bit. The difference lies in the amount of memory they can address. A 32-bit OS can access 4 GB of memory, while a 64-bit OS can address a staggering 17.1 quintillion GB, a massive leap in addressable space.
64-bit OS also boast improved performance due to their ability to process larger data chunks and handle more complex instructions. However, they require 64-bit CPUs and may not be compatible with older 32-bit software.
## Process Management: Juggling the Tasks at Hand
At the heart of an operating system lies its ability to manage multiple processes simultaneously. This involves creating processes, allocating resources, scheduling execution, and ensuring synchronization.
Process creation involves loading the program into memory, allocating runtime stack and heap memory, and assigning input/output handles. The process table, a data structure maintained by the OS, tracks information about each process, such as its state, priority, and resource allocation.
## Multiprogramming: The Art of Balancing Act
Multiprogramming allows multiple processes to reside in memory and share CPU resources, enhancing overall system utilization. The degree of multiprogramming, determined by the long-term scheduler, determines how many processes can be simultaneously active.
## Memory Mapping and Protection: Safeguarding Memory
To prevent unauthorized access and protect memory integrity, operating systems employ memory mapping and protection mechanisms. Virtual address space (VAS) provides each process with private memory space, preventing conflicts and ensuring isolation.
## Conclusion
As technology advances, the role of operating systems will only grow more sophisticated, adapting to the ever-increasing demands of artificial intelligence, cloud computing, and the ever-expanding digital landscape. In the future, operating systems will not only manage hardware and software but also serve as intelligent assistants, anticipating user needs and streamlining complex tasks. They will become the invisible backbone of our digital lives, ensuring seamless interaction and enabling us to harness the full potential of technology. | imsushant12 |

title: Type-Hinting DataFrames for Static Analysis and Runtime Validation

In addition to usage in static analysis (with Pyright and Mypy), these type hints can be validated at runtime with an included decorator.

---
Since the advent of type hints in Python 3.5, statically typing a DataFrame has generally been limited to specifying just the type:
```python
def process(f: DataFrame) -> Series: ...
```
This is inadequate, as it ignores the types contained within the container. A DataFrame might have string column labels and three columns of integer, string, and floating-point values; these characteristics define the type. A function argument with such type hints provides developers, static analyzers, and runtime checkers with all the information needed to understand the expectations of the interface. [StaticFrame](https://github.com/static-frame/static-frame) 2 now permits this:
```python
from typing import Any
from static_frame import Frame, Index, TSeriesAny
def process(f: Frame[ # type of the container
Any, # type of the index labels
Index[np.str_], # type of the column labels
np.int_, # type of the first column
np.str_, # type of the second column
np.float64, # type of the third column
]) -> TSeriesAny: ...
```
All core StaticFrame containers now support generic specifications. While statically checkable, a new decorator, ``@CallGuard.check``, permits runtime validation of these type hints on function interfaces. Further, using ``Annotated`` generics, the new ``Require`` class defines a family of powerful runtime validators, permitting per-column or per-row data checks. Finally, each container exposes a new ``via_type_clinic`` interface to derive and validate type hints. Together, these tools offer a cohesive approach to type-hinting and validating DataFrames.
## Requirements of a Generic DataFrame
Python's built-in generic types (e.g.,``tuple`` or ``dict``) require specification of component types (e.g., ``tuple[int, str, bool]`` or ``dict[str, int]``). Defining component types permits more accurate static analysis. While the same is true for DataFrames, there have been few attempts to define comprehensive type hints for DataFrames.
Pandas, even with the ``pandas-stubs`` package, does not permit specifying the types of a DataFrame's components. The Pandas DataFrame, permitting extensive in-place mutation, may not be sensible to type statically. Fortunately, immutable DataFrames are available in StaticFrame.
Further, Python's tools for defining generics, until recently, have not been well-suited for DataFrames. That a DataFrame has a variable number of heterogeneous columnar types poses a challenge for generic specification. Typing such a structure became easier with the new ``TypeVarTuple``, introduced in Python 3.11 (and back-ported in the ``typing_extensions`` package).
A ``TypeVarTuple`` permits defining generics that accept a variable number of types. (See [PEP 646](https://peps.python.org/pep-0646) for details.) With this new type variable, StaticFrame can define a generic ``Frame`` with a ``TypeVar`` for the index, a ``TypeVar`` for the columns, and a ``TypeVarTuple`` for zero or more columnar types.
A generic ``Series`` is defined with a ``TypeVar`` for the index and a ``TypeVar`` for the values. The StaticFrame ``Index`` and ``IndexHierarchy`` are also generic, the latter again taking advantage of ``TypeVarTuple`` to define a variable number of component ``Index`` for each depth level.
StaticFrame uses NumPy types to define the columnar types of a ``Frame``, or the values of a ``Series`` or ``Index``. This permits narrowly specifying sized numerical types, such as ``np.uint8`` or ``np.complex128``; or broadly specifying categories of types, such as ``np.integer`` or ``np.inexact``. As StaticFrame supports all NumPy types, the correspondence is direct.
## Interfaces Defined with Generic DataFrames
Extending the example above, the function interface below shows a ``Frame`` with three columns transformed into a dictionary of ``Series``. With so much more information provided by component type hints, the function's purpose is almost obvious.
```python
from typing import Any
from static_frame import Frame, Series, Index, IndexYearMonth
def process(f: Frame[
Any,
Index[np.str_],
np.int_,
np.str_,
np.float64,
]) -> dict[
int,
Series[ # type of the container
IndexYearMonth, # type of the index labels
np.float64, # type of the values
],
]: ...
```
This function processes a signal table from an [Open Source Asset Pricing](https://www.openassetpricing.com) (OSAP) dataset (Firm Level Characteristics / Individual / Predictors). Each table has three columns: security identifier (labeled "permno"), year and month (labeled "yyyymm"), and the signal (with a name specific to the signal).
The function ignores the index of the provided ``Frame`` (typed as ``Any``) and creates groups defined by the first column "permno" ``np.int_`` values. A dictionary keyed by "permno" is returned, where each value is a ``Series`` of ``np.float64`` values for that "permno"; the index is an ``IndexYearMonth`` created from the ``np.str_`` "yyyymm" column. (StaticFrame uses NumPy ``datetime64`` values to define unit-typed indices: ``IndexYearMonth`` stores ``datetime64[M]`` labels.)
Rather than returning a ``dict``, the function below returns a ``Series`` with a hierarchical index. The ``IndexHierarchy`` generic specifies a component ``Index`` for each depth level; here, the outer depth is an ``Index[np.int_]`` (derived from the "permno" column), the inner depth an ``IndexYearMonth`` (derived from the "yyyymm" column).
```python
from typing import Any
from static_frame import Frame, Series, Index, IndexYearMonth, IndexHierarchy
def process(f: Frame[
Any,
Index[np.str_],
np.int_,
np.str_,
np.float64,
]) -> Series[ # type of the container
IndexHierarchy[ # type of the index labels
Index[np.int_], # type of index depth 0
IndexYearMonth], # type of index depth 1
np.float64, # type of the values
]: ...
```
Rich type hints provide a self-documenting interface that makes functionality explicit. Even better, these type hints can be used for static analysis with Pyright (now) and MyPy (pending full ``TypeVarTuple`` support). For example, calling this function with a ``Frame`` of two columns of ``np.float64`` will fail a static analysis type check or deliver a warning in an editor.
## Runtime Type Validation
Static type checking may not be enough: runtime evaluation provides even stronger constraints, particularly for dynamic or incompletely (or incorrectly) type-hinted values.
Building on a new runtime type checker named ``TypeClinic``, StaticFrame 2 introduces ``@CallGuard.check``, a decorator for runtime validation of type-hinted interfaces. All StaticFrame and NumPy generics are supported, and most built-in Python types are supported, even when deeply nested. The function below adds the ``@CallGuard.check`` decorator.
```python
from typing import Any
from static_frame import Frame, Series, Index, IndexYearMonth, IndexHierarchy, CallGuard
@CallGuard.check
def process(f: Frame[
Any,
Index[np.str_],
np.int_,
np.str_,
np.float64,
]) -> Series[
IndexHierarchy[Index[np.int_], IndexYearMonth],
np.float64,
]: ...
```
Now decorated with ``@CallGuard.check``, if the function above is called with an unlabelled ``Frame`` of two columns of ``np.float64``, a ``ClinicError`` exception will be raised, illustrating that, where three columns were expected, two were provided, and where string column labels were expected, integer labels were provided. (To issue warnings instead of raising exceptions, use the ``@CallGuard.warn`` decorator.)
<!-- f = Frame(np.random.rand(20).reshape(10,2)) -->
```
ClinicError:
In args of (f: Frame[Any, Index[str_], int64, str_, float64]) -> Series[IndexHierarchy[Index[int64], IndexYearMonth], float64]
└── Frame[Any, Index[str_], int64, str_, float64]
└── Expected Frame has 3 dtype, provided Frame has 2 dtype
In args of (f: Frame[Any, Index[str_], int64, str_, float64]) -> Series[IndexHierarchy[Index[int64], IndexYearMonth], float64]
└── Frame[Any, Index[str_], int64, str_, float64]
└── Index[str_]
└── Expected str_, provided int64 invalid
```
## Runtime Data Validation
Other characteristics can be validated at runtime. For example, the ``shape`` or ``name`` attributes, or the sequence of labels on the index or columns. The StaticFrame ``Require`` class provides a family of configurable validators.
* ``Require.Name``: Validate the ``name`` attribute of the container.
* ``Require.Len``: Validate the length of the container.
* ``Require.Shape``: Validate the ``shape`` attribute of the container.
* ``Require.LabelsOrder``: Validate the ordering of the labels.
* ``Require.LabelsMatch``: Validate inclusion of labels independent of order.
* ``Require.Apply``: Apply a Boolean-returning function to the container.
Aligning with a growing trend, these objects are provided within type hints as one or more additional arguments to an ``Annotated`` generic. (See [PEP 593](https://peps.python.org/pep-0593) for details.) The type referenced by the first ``Annotated`` argument is the target of subsequent-argument validators. For example, if a ``Index[np.str_]`` type hint is replaced with an ``Annotated[Index[np.str_], Require.Len(20)]`` type hint, the runtime length validation is applied to the index associated with the first argument.
Extending the example of processing an OSAP signal table, we might validate our expectation of column labels. The ``Require.LabelsOrder`` validator can define a sequence of labels, optionally using ``...`` for contiguous regions of zero or more unspecified labels. To specify that the first two columns of the table are labeled "permno" and "yyyymm", while the third label is variable (depending on the signal), the following ``Require.LabelsOrder`` can be defined within an ``Annotated`` generic:
```python
from typing import Any, Annotated
from static_frame import Frame, Series, Index, IndexYearMonth, IndexHierarchy, CallGuard, Require
@CallGuard.check
def process(f: Frame[
Any,
Annotated[
Index[np.str_],
Require.LabelsOrder('permno', 'yyyymm', ...),
],
np.int_,
np.str_,
np.float64,
]) -> Series[
IndexHierarchy[Index[np.int_], IndexYearMonth],
np.float64,
]: ...
```
If the interface expects a small collection of OSAP signal tables, we can validate the third column with the ``Require.LabelsMatch`` validator. This validator can specify required labels, sets of labels (from which at least one must match), and regular expression patterns. If tables from only three files are expected (i.e., "Mom12m.csv", "Mom6m.csv", and "LRreversal.csv"), we can validate the labels of the third column by defining ``Require.LabelsMatch`` with a set:
```python
@CallGuard.check
def process(f: Frame[
Any,
Annotated[
Index[np.str_],
Require.LabelsOrder('permno', 'yyyymm', ...),
Require.LabelsMatch({'Mom12m', 'Mom6m', 'LRreversal'}),
],
np.int_,
np.str_,
np.float64,
]) -> Series[
IndexHierarchy[Index[np.int_], IndexYearMonth],
np.float64,
]: ...
```
Both ``Require.LabelsOrder`` and ``Require.LabelsMatch`` can associate functions with label specifiers to validate data values. If the validator is applied to column labels, a ``Series`` of column values will be provided to the function; if the validator is applied to index labels, a ``Series`` of row values will be provided to the function.
Similar to the usage of ``Annotated``, the label specifier is replaced with a list, where the first item is the label specifier, and the remaining items are row- or column-processing functions that return a Boolean.
To extend the example above, we might validate that all "permno" values are greater than zero and that all signal values ("Mom12m", "Mom6m", "LRreversal") are greater than or equal to -1.
```python
from typing import Any, Annotated
from static_frame import Frame, Series, Index, IndexYearMonth, IndexHierarchy, CallGuard, Require
@CallGuard.check
def process(f: Frame[
Any,
Annotated[
Index[np.str_],
Require.LabelsOrder(
['permno', lambda s: (s > 0).all()],

),

np.float64,
]) -> Series[
IndexHierarchy[Index[np.int_], IndexYearMonth],
np.float64,
]: ...
```
If validation fails, ``@CallGuard.check`` will raise an exception. For example, if the above function is called with a ``Frame`` that has an unexpected third-column label, the following exception will be raised:
<!-- >>> f = sf.Frame.from_records(([3, '192004', 1.0], [3, '192005', -2.0]), columns=('permno', 'yyyymm', 'Mom3m')) -->
```
ClinicError:
In args of (f: Frame[Any, Annotated[Index[str_], LabelsOrder(['permno', <lambda>], 'yyyymm', ...), LabelsMatch([{'Mom12m', 'LRreversal', 'Mom6m'}, <lambda>])], int64, str_, float64]) -> Series[IndexHierarchy[Index[int64], IndexYearMonth], float64]
└── Frame[Any, Annotated[Index[str_], LabelsOrder(['permno', <lambda>], 'yyyymm', ...), LabelsMatch([{'Mom12m', 'LRreversal', 'Mom6m'}, <lambda>])], int64, str_, float64]

└── Expected label to match frozenset({'Mom12m', 'LRreversal', 'Mom6m'}), no provided match
```
## The Expressive Power of ``TypeVarTuple``
As shown above, ``TypeVarTuple`` permits specifying ``Frame`` with zero or more heterogeneous columnar types. For example, we can provide type hints for a ``Frame`` of two float or six mixed types:
```python
>>> from typing import Any
>>> from static_frame import Frame, Index
>>> f1: sf.Frame[Any, Any, np.float64, np.float64]
>>> f2: sf.Frame[Any, Any, np.bool_, np.float64, np.int8, np.int8, np.str_, np.datetime64]
```
While this accommodates diverse DataFrames, type-hinting wide DataFrames, such as those with hundreds of columns, would be unwieldy. Python 3.11 introduces a new syntax to provide a variable range of types in ``TypeVarTuple`` generics: star expressions of ``tuple`` generic aliases. For example, to type-hint a ``Frame`` with a date index, string column labels, and any configuration of columnar types, we can star-unpack a ``tuple`` of zero or more ``All``:
```python
>>> from typing import Any
>>> from static_frame import Frame, Index
>>> f: sf.Frame[Index[np.datetime64], Index[np.str_], *tuple[All, ...]]
```
The ``tuple`` star expression can go anywhere in a list of types, but there can be only one. For example, the type hint below defines a ``Frame`` that must start with Boolean and string columns but has a flexible specification for any number of subsequent ``np.float64`` columns.
```python
>>> from typing import Any
>>> from static_frame import Frame
>>> f: sf.Frame[Any, Any, np.bool_, np.str_, *tuple[np.float64, ...]]
```
## Utilities for Type Hinting
Working with such detailed type hints can be challenging. To aid users, StaticFrame provides convenient utilities for runtime type hinting and checking. All StaticFrame 2 containers now feature a ``via_type_clinic`` interface, permitting access to ``TypeClinic`` functionality.
First, utilities are provided to translate a container, such as a complete ``Frame``, into a type hint. The string representation of the ``via_type_clinic`` interface provides a string representation of the container's type hint; alternatively, the ``to_hint()`` method returns a complete generic alias object.
```python
>>> import static_frame as sf
>>> f = sf.Frame.from_records(([3, '192004', 0.3], [3, '192005', -0.4]), columns=('permno', 'yyyymm', 'Mom3m'))
>>> f.via_type_clinic
Frame[Index[int64], Index[str_], int64, str_, float64]
>>> f.via_type_clinic.to_hint()
static_frame.core.frame.Frame[static_frame.core.index.Index[numpy.int64], static_frame.core.index.Index[numpy.str_], numpy.int64, numpy.str_, numpy.float64]
```
Second, utilities are provided for runtime-type-hint testing. The ``via_type_clinic.check()`` function permits validating the container against a provided type hint.
```python
>>> f.via_type_clinic.check(sf.Frame[sf.Index[np.str_], sf.TIndexAny, *tuple[tp.Any, ...]])
ClinicError:
In Frame[Index[str_], Index[Any], Unpack[Tuple[Any, ...]]]
└── Index[str_]
└── Expected str_, provided int64 invalid
```
To support gradual typing, StaticFrame defines several generic aliases configured with ``Any`` for every component type. For example, ``TFrameAny`` can be used for any ``Frame``, and ``TSeriesAny`` for any ``Series``. As expected, ``TFrameAny`` will validate the ``Frame`` created above.
```python
>>> f.via_type_clinic.check(sf.TFrameAny)
```
## Conclusion
Better type hinting for DataFrames is overdue. With modern Python typing tools and a DataFrame built on an immutable data model, StaticFrame 2 meets this need, providing powerful resources for engineers prioritizing maintainability and verifiability.

1,665,641 | Playwright with GitHub Actions | Playwright is a fantastic tool for doing reliable end-to-end testing for your web application. By... | 0 | 2023-11-13T20:29:24 | https://dev.to/stefanalfbo/playwright-with-github-actions-4m6i | 100daystooffload, playwright, githubactions, testing | [Playwright](https://playwright.dev/) is a fantastic tool for doing reliable end-to-end testing for your web application.
By using Playwright with [GitHub Actions](https://docs.github.com/en/actions), you can automate your end-to-end tests to run on every push or on a specific time to ensure that your web application is always working as expected.
Here is a step-by-step guide on one way to do this:
1. This guide assumes that there is a Playwright project located on this path of your repository, `./tests/web-application`
2. Create a new workflow file in your repository which will define the steps that will be executed when the workflow is triggered.
```bash
# Assumes that we are in the root of the repository
mkdir -p ./.github/workflows
touch ./.github/workflows/end-to-end-tests.yml
```
3. Edit the new file, `end-to-end-tests.yml`, with your favorite IDE and add the following snippet at the top.
```yml
name: end-to-end-tests
on:
schedule:
- cron: '0 23 * * 1-5'
workflow_dispatch:
```
This will name the workflow in the Actions tab to `end-to-end-tests` and will be triggered Monday to Friday 23:00 UTC. The `workflow_dispatch` makes it possible to trigger the action manually from GitHub UI.
4. Next we will define our job in the workflow file for running our Playwright tests.
```yml
jobs:
run-playwright-tests:
timeout-minutes: 60
runs-on: ubuntu-latest
defaults:
run:
working-directory: ./tests/web-application
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v3
with:
node-version: 18
- name: Install dependencies
run: npm ci
- name: Install Playwright
run: npx playwright install --with-deps
- name: Run Playwright tests
run: npx playwright test
- uses: actions/upload-artifact@v3
if: ${{ failure() }}
with:
name: playwright-report
path: tests/web-application/playwright-report
retention-days: 5
```
This job will run the tests, and if any of test fails it will use the `actions/upload-artifact@v3` to upload the Playwright test report to the action view on GitHub. **Note:** That the `path` needs to be the full path even if we have defined a `working-directory`.
5. Commit your changes and push them to the repository.
Once you have pushed your changes, GitHub Actions will automatically trigger your workflow at the scheduled time or if you can't wait, you can manually trigger it.
If any of the tests fail, the workflow will fail and you will receive a notification. You can then investigate the failing tests by downloading the report from the failed action on GitHub.
I usually set, `video: 'retain-on-failure'`, in the Playwright configuration file so I will be able to see videos for the failed tests. Another setting that might be of interest is to set, `trace`, also.
So far the experience with Playwright and GitHub together been great, and I can highly recommend it.
Happy testing! | stefanalfbo |

Who... | 9,282 | 2023-11-14T09:12:05 | https://dev.to/jmfayard/why-real-developers-should-rewrite-everything-in-rust-in-2024-2hh | career, rust, beginners, writing | The title speaks for itself but you are such a bunch of loosers that I will do a FAQ anyway.
**Who should read this article ?**
Everyone should always read my articles.
At least if you don't want to be a looser.
**What do I know about my intended audience ?**
That they should rewrite everything in Rust in 2024 unless they want to stay a bunch of loosers in 2024.
**What is a looser and what is a real developer ?**
Basically it's like black and white, either you are a looser or you are a [real developer](https://en.wikipedia.org/wiki/No_true_Scotsman).
**What is Rust in 2024 ?**
Same as Rust in 2023, one year older.
Long story short, it's a programming language with awesome features that you should rewrite everything with in 2024.
**Why in 2024 ?**
Great for SEO.
**What do I mean by everything ?**
Everything where code is involved where Rust awesome features might become handy at some point in 2024.
**How much time and money would that cost ?**
I don't know but I know that staying a looser for your whole life wil cost you even more.
**It's loser with one o**
Only in Real English.
I speak Looser English, meaning French.
**How do I use Rust on the front end ?**
[Don't be a Female, Just Google It](https://dev.to/t/shecoded/top/infinity)

1,666,053 | Automated, Secure Real-Estate Settlement via Smart Contracts | The settlement or closing process in traditional real estate is a dynamic operation involving a great... | 0 | 2023-11-14T09:47:15 | https://dev.to/oodlesblockchain/automated-secure-real-estate-settlement-via-smart-contracts-478l | smartcontract, automation, blockchain, beginners | The settlement or closing process in traditional real estate is a dynamic operation involving a great deal of time, energy, and attention. The land transfer process stayed the same for decades. However, [smart contract Development](https://blockchain.oodles.io/smart-contract-development-services/) with Blockchain for real estate offers real change and an efficient alternative to the settlement process.
## Real Estate Settlement
The closing of real estate is the transition of a real-estate title from a seller to a buyer according to the selling contract. In the process, the buyer gets the property title and the seller gets the money. There are, however, various settlement prerequisites and expenses that make it more complicated than purchasing something at a supermarket. The sales contract itself accounts for both requirements and costs. Many real estate closings use an escrow agent's services, which acts as a third party that both the buyer and the seller must trust. An escrow manages the activities between a buyer and a seller through an agreement of sale and purchase. However, in typical contexts, this trust is always constrained and can be compromised. The cost of closing the mortgage varies from 3 percent to 6 percent.
## Real Estate Settlement | What are the Challenges
Trustless automation with protection has tremendous potential to offer benefits like increased production, improved resource efficiency, and enhanced product and service offering. Most sectors have already reaped the benefits of automation, from e-commerce to electronics manufacturing. Yet the real estate industry has been an exception. Besides, the process of purchasing property is based on three factors, including paperwork (document signing), transfer of payment, and transfer of ownership.
Too many parties currently have to be involved in the property closing process and each of these parties uses their software.
Also, escrow companies help to build trust between traditional real estate transactions, but with a price. Also, they remain vulnerable to human actions (such as error and greed).
To simplify real-estate settlement without using an escrow, one single place is required where a buyer, a seller, agents, and a title company can meet. Therefore, a transaction needs a buyer and a seller to create and guarantee trust.
Also, read | [Blockchain Smart Contracts in Real Estate: A Long-Awaited Breakthrough](https://blockchain.oodles.io/blog/blockchain-based-smart-contracts-real-estate/)
## Can Smart Contracts substitute Escrow from Real-Estate Settlement?
Smart blockchain contracts have emerged as a challenge to the Escrow agencies' life. These are documents that are stored on the blockchain and translated into computer code. Smart contracts immediately execute a contract upon fulfillment of pre-defined terms, without having a middleman, leading to a quick settlement and closing. Once all parties sign the agreement digitally when carrying out their duties, a smart contract immediately releases the deed to the buyer and the money to the seller. Therefore, the escrow fees are practically removed.
It is not just a philosophical theory, though. The cycle of substituting Escrow businesses for smart contracts is well underway. The automation of acquisitions of property by settlement procedures is a fact that many successful cases back.
## How it works - An Imaginary Scenario
On the blockchain, we'll record and execute a real estate purchase. For example, Bob buys an apartment in his American home in Manchester, England, while he lives overseas. The property payment will happen with Ethereum's Ether ( ETH) and payable to a smart contract.
Bob signs a purchasing agreement, sends ETH to a particular address and awaits the seller to submit the final signed document with a notary. Then, the smart contract executes the rest of the transaction by giving the respective parties both the ETH and the deed. All this while blockchain records all aspects of the contract permanently. In the future, if any of the contracting parties make a claim, the data on the blockchain would be publicly available to come into use as proper evidence.
There was no escrow in place for the transaction in this case. Surely, finding a seller to agree to accept payment in crypto and process the transaction through a smart contract program can be very challenging. Nonetheless, this hypothetical use case shows to some degree that smart contracts are entirely capable of handling the intermediary position that Escrow companies undertake.
Also, read | [Applications of Smart Contracts in Today's Businesses](https://blockchain.oodles.io/blog/smart-contract-applications-business-use-cases/)
## Can Smart Contracts go Mainstream
Lately, using cryptocurrency has occurred to be the use case for property transactions. However, there are more secure alternatives that might attract more traditional real estate agencies.
The primary issue with executing any cryptocurrency transaction is the volatility issue. Bitcoin, Ethereum, and other top coins can easily change 15 percent in a single day. Many are uncomfortable taking chances on big transactions like real estate purchases. Smart contracts using fiat money are entirely feasible and gain popularity due to the relative fiat stability.
## What’s next
Imagine living in a society where purchasing real estate is instantaneous, easy, safe, and digital. Real estate professionals might take on more specialised employment opportunities by reducing resources by substituting computer protocols for laborious operations.
Automation is no longer impossible in the real estate transaction phase. It is a working concept in which companies like Oodles are working and constantly improving. We understand the technology's potential and therefore, create settlement protocols powered by smart contracts that can eventually achieve broad acceptance.

1,666,061 | Augmented Reality (AR) in Healthcare: Revolutionizing the Future of Medicine | Introduction The healthcare industry is transforming remarkably, driven by technological... | 0 | 2023-11-14T09:56:54 | https://dev.to/xcubelabs/augmented-reality-ar-in-healthcare-revolutionizing-the-future-of-medicine-677 | augmentedreality, ar, healthcare, product | **Introduction**
The healthcare industry is transforming remarkably, driven by technological advancements and a growing demand for personalized patient experiences. Augmented Reality (AR) has emerged as a powerful tool in healthcare, potentially revolutionizing various aspects of medical practice, from surgical procedures to patient education and diagnosis. By integrating digital content into the real world, AR in healthcare is reshaping how services are delivered, improving efficiency, accuracy, and overall patient care.
**AR Surgery: Enhancing Precision And Visualization**
One of the most significant applications of AR in healthcare is in surgical procedures. Surgeons can now wear AR headsets, allowing them to visualize critical information without turning away from the task at hand. By superimposing computer-generated imagery onto the real-world view, AR enables surgeons to see patient imagery, such as CT scans, in real-time during the operation. This technology provides surgeons with precise guidance and enhances their ability to make accurate decisions, improving surgical outcomes. Additionally, AR combined with AI software can process vast amounts of data and provide on-the-fly diagnoses or procedural suggestions directly in the surgeon’s field of view.
**Medical Visualization: Enhancing Patient Care Beyond The Operating Room**
Augmented reality in the medical field has given rise to AR tools that have been developed to superimpose visuals on patients, enhancing the delivery of safer and more efficient care beyond the operating room. For example, nursing staff can use AR overlays to easily identify the right vein when administering medicine, reducing the need for trial and error. This not only improves patient comfort but also minimizes the risk of complications. Furthermore, AR can be used to help patients visualize their own bodies, understand their conditions, and gain insights into specific procedures. By personalizing the patient experience with AI, healthcare providers can tailor visualizations to individual health data, empowering patients to take an active role in their own care.
**Improved Patient Diagnosis: AR As A Diagnostic Aid**
AR in healthcare plays a crucial role in improving patient diagnosis, particularly in cases where verbal descriptions may be inadequate. Patients often struggle to accurately describe their symptoms, leading to delays in diagnosis and treatment. AR can help bridge this communication gap by allowing patients to visually compare their symptoms to different skin conditions or experience various eye conditions. This visual aid enhances the patient’s ability to describe their concerns to healthcare providers accurately, leading to more timely and accurate diagnoses.
**Pain Management: AR For Therapeutic Purposes**
AR, along with its counterpart, Virtual Reality (VR), has proven to be effective in pain management. Patients can be immersed in therapeutic environments controlled by healthcare professionals, providing a distraction from pain and promoting relaxation. The FDA has already approved VR-based systems that use cognitive behavioral therapy to help patients cope with chronic pain. Similarly, AR can be used during physical therapy sessions to minimize discomfort and improve patient engagement. By integrating data on the patient’s specific pain, AI can personalize the pain management experience, optimizing treatment outcomes.
**Immersive Training: AR For Healthcare Education**
AR in healthcare has become invaluable for healthcare education and training. Medical students and professionals can explore the human body, practice procedures, and learn new techniques in virtualized environments that closely resemble real-world scenarios. AI technology enhances these training experiences by providing real-time feedback and adapting the virtual environment based on user actions. This interactive and immersive learning approach facilitates a deeper understanding of complex medical concepts and prepares healthcare professionals for real-world practice. Furthermore, AR in healthcare allows for remote collaboration, enabling students in a classroom to observe and learn from their peers wearing AR glasses.
**The Vast Potential Of AR In Healthcare**
While we have only scratched the surface of what AR and AI can accomplish in healthcare, the possibilities for future innovations are immense. AR and AI have the potential to transform healthcare delivery, from improving surgical precision and patient education to enhancing diagnostics and pain management. The integration of AR technology with online collaboration tools enables healthcare professionals to consult with each other remotely, providing guidance and support even when physically distant. Pharmaceutical and genomics companies can leverage AR and AI to visualize, analyze, and develop new drugs, viruses, and therapies, opening new frontiers in medical research and development.
To fully harness the benefits of AR in healthcare, organizations must invest in education and training to familiarize medical staff with AR-supported tools. Implementing small-scale pilot projects can help mitigate the fear of change and ensure that healthcare providers stay up-to-date with the evolving AR industry. By embracing AR and AI, healthcare organizations can enhance patient care, improve efficiency, and pave the way for a healthier future.
**Conclusion**
Augmented Reality (AR) is revolutionizing the healthcare industry, providing unprecedented opportunities to improve patient care, enhance surgical procedures, and transform medical training. The integration of AR technology with AI capabilities enables healthcare professionals to visualize critical information, personalize patient experiences, and make more accurate diagnoses. From surgical visualization and patient education to pain management and immersive training, the applications of AR in healthcare are diverse and promising.While challenges such as the cost of AR products and data security concerns remain, the potential benefits outweigh the obstacles. The global market for AR in healthcare is projected to experience significant growth in the coming years, driven by increased adoption, investments, and advancements in technology. As the healthcare industry continues to embrace digital transformation, AR will play a vital role in shaping the future of medicine, delivering better, safer, and more personalized care to patients worldwide.

when I synced data using Navicat from local to RDS, I found the SQL query results with `order by create_time DESC` was **incorrect**.
I guessed that may be relative to the SQL client's time_zone setup, cause I have met such a problem before when I work as a Frontend Engineer.
So I decided to dig into this issue and get the proper resolution.
## Firstly
, look at the time_zone setup of your Mysql client using this command
```
show variables like '%time_zone%'.
```
### result of my local Mysql client
### result of RDS
The time_zone setup is absolutely different!. Let's make a query by `SELECT create_time FROM order_deposits WHERE id=37;`
### result of local
### result of RDS
The result of this query is absolutely the same.

Not a method. Not a class. Not a framework. Just a function. - _John Carmack. Oculus VR CTO._
When I started to learn React, I didn't read about its basic concepts. I directly jumped into writing React code because I found it trendy. However, not long into that journey, I faced the consequences of writing code without understanding its benefits.
I finally understood what Ali Abdaal meant when he said, "**_Learning and Practicing should be balanced together._**"
Nonetheless, Hooks were one of the concepts that I had skipped theoretically. I knew how to write them and where to use them, but I wasn't aware of why we use them.
I understood the intricacies of React Hooks, so you don't have to. I will help you learn what they are, why and how to use them in this article.
## What are Hooks?
By definition, _hooks are functions in React that allow us to access and verify specific properties of UI elements, like their current state, without writing classes, constructors, etc._
_Hooks allow you to perform operations that Vanilla JS cannot_. React has different built-in hooks - State Hooks, Context Hooks, Ref Hooks, Effect Hooks, etc.
You are probably writing a hook in your code when you smash a random word with the `use` keyword and call it a function that deconstructs an array into variables.
Hooks uses features of the React framework, like SSR, to perform a specific task from within a component. However, the hooks do not live inside your React component.
More often than not, these hooks perform basic operations, like trying to check the state of a UI element and whether the user interacted with it.
Hooks allow us to use reusable states of components without changing their hierarchy. With hooks, developers can extract the current state of a UI element, grab DOM elements, and more independently and re-use those states and information in other components without creating extra classes, constructors, props, etc.
We can also create custom hooks, which I will cover in a separate article, and for now, let us look at an example where hooks would be required. Then, we will understand why we need them and how to use them.
### E-Commerce Example
Consider yourself running an E-commerce brand. You have a page that displays your product with checkboxes to select the size, colour, etc. By default, the chosen choice is the first choice.
If you want to check whether the user has selected a different choice, you require something directly into your component that verifies the current state of those selection boxes. A hook allows you to do that, specifically, the `useState()` hook.
Therefore, the `useState()` hook returns the current state of UI elements and performs specific operations accordingly. These actions may include changing the product URL and attaching queries for the user to share.
There are more hooks. If I want to select HTML elements from the DOM, I can use the `useRef()` hook. If not using React, I would pick the elements with the `querySelector()` method, etc.
React hooks represent those operations that could work manually without a framework, but the complexity of frameworks wouldn't allow us to continue doing so. Thus, we efficiently implement those basic operations and insert additional benefits.
Of course. Before hooks, developers accessed the state of UI elements and other details, but the downside of those features was writing extra code.
Let's see why the React team introduced hooks and what developers used before them to access the states of UI elements.
## Why use Hooks?
Nowadays, websites aren't static. There are buttons, checkboxes, text input boxes, crazy animations, etc. A lot is going on at the same time. Developers require various techniques to keep up with these changes in the UI elements and manage them accordingly.
They require various features in their choice of frameworks to swiftly grab user input, such as scrolling behaviour by writing less code. They want to select HTML elements, access their states, receive information from parent elements, etc.
In those cases, we use hooks. Whenever there's a change, the `useState()` hook keeps track of those changes and gets user input. Whenever you want to grab information from parent nodes and pass that information as props to child nodes, you can use `useContext()`, and so on.
However, if you think about it deeply, developers had to grab user input even before the React team introduced hooks. _React released Hooks in React 16.8 in early 2019_.
**So, what did developers use before 2019?**
At that time, React implemented features in ways that most developers hated. _They forced front-end developers to use constructors inside classes with render props for the application to understand the current state of various UI components and use the data provided by the user to perform given actions_.
Hooks allowed React developers to eradicate class-based components and directly render the UI with stateful logic and dynamic data from functional components. These functional components were not "_dumb components_" anymore.
The implementations of React class components were on the pure JavaScript syntax, and its Vanilla implementation inherited the disadvantages of JavaScript classes, including the excessive use of the `this` keyword.
React didn't bother to create a class system either. They said they were not in the business of building a class system and further adopted the default system of JavaScript. All of these problems combined led to the following code.
This is a small example of a class-based code snippet from Fireship trying to increment the count stored in a state wherein the user clicks on the button and displays the current count via an HTML element to the user.
The classes and constructors before early 2019 started to give Java vibes. Back then, only React class components handled states and other DOM-based functionalities. The functional components were merely responsible for displaying information to the user through UI elements.
Functional components till 16.8 received data in the form of props from parent components and precisely displayed them to the user. Developers hated React for that approach. So, React decided to introduce Hooks.
Grabbing data from parent elements, attaining states, and other features were delegated to Hooks.
Oh, and by the way, A state in React keeps track of how data changes in the application. It holds data in different forms that belong to a UI element. For example, it could store user input whenever the user types inside a textbox.
Before Hooks, React was a mess compared to the advancements of today. Classes and constructors led to a wrapper hell. We had to pass a component into another component, and so on.
Developers claimed frameworks provided seamless experience and faster performance.
The entire idea of writing a class with other "yada yada" render props and high-order functionalities to solely check if a user selected a checkbox option contradicted their claim that frameworks were better than plain Vanilla JS.
I wonder why Java developers found themselves inferior. So, the React team decided to step up their game. They introduced hooks that allowed us to access the state of UI elements through functions within React components without being in the same context of a framework.
## How to use them?
For starters, you cannot create hooks everywhere. You can only initialize them in the top level of a component.
You cannot initiate them inside loops, conditionals, nested functions, etc. Otherwise, you can initialize them inside custom hooks strictly.
```
import "./App.css";
import { useState } from "react"; // Import the hook
function App() {
const [names, setName] = useState("Afan"); // Initialize the hook
return (
<div className="App">
<p>{names}</p>
<input
type="text"
placeholder="Enter your name"
onChange={(e) => {
setName(e.target.value);
}}
></input>
</div>
);
}
export default App;
```
I used the `useState()` hook in this example. It keeps track of the current state of a UI element. When the state changes, we use the setter function provided by the second deconstructed array element named `setName()` to set a new value to the first deconstructed value.
The `useState()` hook simultaneously re-renders the UI element whenever the state of an element changes to update the UI elements using the data provided by a hook. The first variable in that hook array stores the data, and the second one is a setter used to collect the information from the UI element.
`useState()` solely accepts one optional parameter, which is the default value of the state. In other words, `Afan` is the default value of the `<p>` tag and other UI elements using that hook to display values. This default value can be in strings, numbers, empty arrays `([])`, empty objects `({})`, etc.
During the days of Classes and Constructors, objects represented the initial default value. Nonetheless, the brackets are required when initializing a hook. Those brackets represent the concept of Array Deconstruction.
However, the variables inside those brackets aren't arrays. We can use multiple hooks in the same component. Mostly, we use `useState()` to keep track of the user input through a form. Forms contain more than one field. Hence, we can initialize multiple hooks with different variable names and initial values at the beginning of the component function itself.
Similarly, you can initialize other hooks. All components using the same hook in the same file are also re-rendered whenever the state of that UI element changes.
Every component that uses the data stored in the state will get re-rendered along with the entire page. React will modify and update those components together. Developers will not manually select each HTML element. Instead, React with its Babel will do that for us to update those components.
Furthermore, hooks are asynchronous. If you try to call them multiple times, they will only re-render the component once in specific scenarios.
```
import "./App.css";
import { useState } from "react";
function App() {
const [names, setName] = useState("Afan");
function updateP(e) {
setName(e.target.value + "HEY");
setName(e.target.value + "HELLO");
setName(e.target.value + "HOWDY"); // Only this setter function called
}
return (
<div className="App">
<p>{names}</p>
<input
type="text"
placeholder="Enter your name"
onChange={(e) => updateP(e)}
></input>
</div>
);
}
export default App;
```
I created the `updateP()` function inside the main `App()` function component and called the hook from that function. I invoked it three times, but only the last one executed and appended HOWDY to the modified string when it re-rendered.
I earlier claimed that hooks cannot reside inside functions, loops, etc. So, how the heck am I using them here? Well, you can invoke the setter function of the hooks inside functions, but you cannot create hooks inside functions.
You can only create them at the top level of the component function. However, if you want the current string value to get appended with the previous value and invoke the setter function three times synchronously, you can use a callback function inside it.
```
import "./App.css";
import { useState } from "react";
function App() {
const [count, setCount] = useState(0);
function updateP() {
setCount((prev) => prev + 1);
setCount((prev) => prev + 1);
setCount((prev) => prev + 1);
}
return (
<div className="App">
<p>{count}</p>
<button onClick={updateP}>Increase</button>
</div>
);
}
export default App;
```
This example uses the default value provided in the hook. When the user clicks the button, the function `updateP()` gets invoked, and the count changes.
Since I passed a default value present inside the `useState()` hook, those setter functions can use them and keep updating the previous value when I pass them as parameters.
Inside the button, the function call doesn't require parenthesis. Otherwise, the entire application will enter an infinite loop of function calls. If the parenthesis is attached, the function will get invoked directly before the user clicks the button.
In reality, the hook data lives outside the component that renders it. It is one level outside the component. Even without the respective context, hooks allow us to access that data and restrict its usage if it is confidential since it resides outside the component.
Whenever the state of the component changes, React re-renders the entire page and delivers the data by storing it in the first array element of the `useState()` function.
Also, there's no strict rule about writing the names of the variables deconstructed from hooks. We use the keyword `set` for the setter function because it is easier for other developers and ourselves to understand.
Furthermore, we usually define those variables in combination. So, trying to get the first and last name of the user, the hook will have `[firstName, setFirstName]`, `[lastName, setLastName]`, etc.
It is simply a convention commonly used by React developers while writing hooks to make them easily readable and understandable.
## Without Hooks and Constructors
We understand that React recently introduced hooks in early 2019. Before that, developers used Classes and Constructors. Java developers felt inferior.
However, some will argue that we don't require constructors or hooks to take user input from UI elements and display them. We can do it directly instead. For that, let's consider a click counter-example.
I will try to directly update the values of a counter by storing them inside a variable, updating them whenever the user interacts with the component, and displaying the updated value to the user.
I will exhibit the counter variable inside the `<p>` tag, and whenever I click on the button, it will update the UI element with the new incremented counter.
```
import "./App.css";
function App() {
let counter = 5;
function updateP() {
counter++;
console.log(counter);
}
return (
<div className="App">
<p>{counter}</p>
<button onClick={updateP}>Increase</button>
</div>
);
}
export default App;
```
However, when you try to display the new updated value to the user during their interaction with your UI elements, the count variable will get the updated value, not the component.
The counter updates inside the variable, but the UI will not update because we are not using any function forcing React to re-render the component with its new data.
There should be a trigger that refreshes the component and paints the new values.
When using hooks, React updates the variable with the data using the setter function, and developers access the updated data using the first element in the deconstructed array.
They call the hook to grab the data from within the React components.
However, both array elements are useless if React doesn't re-render the page. When the page re-renders, the new data gets displayed to the user. Since the setter functions in hooks trigger the components to re-render, the UI gets updated too.
And that's why either hooks or classes are required. Only specific hooks, like `useState()`, re-render the page. It is the most commonly used hooks in the majority of applications.
Instead of manually selecting DOM elements, updating the variables of each component that uses the data, and writing that much code, hooks make our lives easier.
---
## Summary
Hooks are functions that developers can invoke or call from within React components. They can access specific information from UI elements, such as user input, grab HTML elements, provide context, etc.
The information attained from UI elements is stored one level outside the React components but within the same exported function.
Hooks allow developers to perform various operations that Vanilla JS will fail to perform. Mostly, we use specific hooks to keep track of the state of a UI element using the `useState()` hook.
The `useState()` hook allows us to access the details provided by the user or perform actions based on the interactions from the user, like scrolling through an element or clicking a button.
Before hooks, developers used Classes and Constructors. That approach required us to write more code. Therefore, the React team introduced Hooks. We cannot manually reciprocate the functionalities of these hooks, like the `useState()` hook.
If we try to replicate the behaviour of the `useState()` hook and manually update variables, the UI elements will continue to remain the same and not update because hooks cause React to re-render the entire page while keeping track of the last stored values of UI elements and their states.
Each hook has a unique proposition that solves a problem wherein Vanilla JS fails. Hooks take advantage of the features of the React framework.
_And that's it._

Most of y'all probably who found me via my popular [post about Russian Peasant Multiplication Alogrithms](https://dev.to/geauxweisbeck4/cool-algorithms-pt-1-russian-peasant-multiplication-66a) - it's worth a read and I intend to continue this series now that I have access to my account again.
1,127 followers is a lot of people to have follow your account, at least to someone who hasn't fully blossomed into their content creation potential quite yet. This motivated me to really brainstorm and create a plan of action for creating quality content and sharing it with others, something I always wanted to do, but never took action on. There are many reasons why I haven't started creating more content, but I see it as an opportunity right now while I face a very challenging time in my life.
This isn't something that's really easy to share, but I have been homeless for all 11 months of 2023 - it's a long story that you can find on many of the links I'll be sharing, but basically I have been unable to find work or housing and need to do something different to elevate myself out of my current situation.
I hope by sharing my story and the knowledge I have obtained by teaching myself programming over the last three years with others, that goodwill may come back around and help me financially - whether that be donations, sponsorships, or a job doesn't really matter to me. I just really need help and that's why I'm asking you to help me out by sharing my content.
## Experiencing Homelessness as a Full Stack Developer
To say this year has been a struggle would be an understatement. Since January 11th, my fiance and I have not had a place to live and have spent most of the year either sleeping on the ground, in a tent, or in the rare case we can afford it, a hotel room. We have experienced more than just losing our home. Over the course of 2023 we have had to deal with:
- Losing our two beloved cats when they ran away from our Jeep
- A Jeep that was stolen from the side of the road one night after our tire blew out
- My dog getting lost numerous times and even getting kidnapped and taken from us for a month (we're dealing with a similar situation again right now)
- Rejection from literally hundreds of jobs due to our living situation (I've applied to over 1,000 jobs in the last three years)
- Got heat stroke and people stole my laptop, my cell phone, and even my glasses while I was getting picked up by EMS
- My fiance lost her job of two and a half years at the end of July due to our housing situation
There's really more to go on about, but I will leave that for you to explore more at the [Homeless Hacker blog website](https://homelesshacker.dev). It is a work in progress, but that is the central home of all my content experimenting for the foreseeable future.
Now I don't say all of this to make you feel bad for us, but I just want to paint a picture for you about how hard this has been to get out of this situation. You don't get treated very well overall when your homeless and it doesn't really matter if you're a good developer or not - it's near impossible to get a software job when you have no power in the tent you live in.
Despite how hard everything has been, I have managed to still code almost everyday when my computer hasn't been in the pawn shop, stolen, or broken down. I've become a pretty damn good programmer if I'd say so myself. I want to share that knowledge by creating educational content and using my writing skills to start making some money.
How will I do that you are probably wondering? I'd like to introduce you to my new personal content creator brand, the Homeless Hacker.
## Introducing the Homeless Hacker
I really don't think there is a better fitting name than the Homeless Hacker. It's funny in a way, but it also really portrays myself as web developer over the last year. While I didn't have a job per say, I have worked on projects. But I will say I have become a much more creative and gritty programmer, and everything has sort of come together much easier for me for whatever reason.
If there is at least one way that you could really help me that is not financial or helping me with a job, I would be so grateful if you followed me and shared my accounts with your followers. You can find myself and the Homeless Hacker at the following links:

1,667,675 | How we helped raise $13.25 millions of dollars at a $149 million evaluation in web3 - The Odyss3y | How we helped raise $13.25 millions of dollars for Web3 startups at a $149 million... | 0 | 2023-11-16T12:00:00 | https://dev.to/relate/how-we-helped-raise-1325-millions-of-dollars-at-a-149-million-evaluation-in-web3-the-odyss3y-lc7 | crypto, startup, branding, blockchain | ## How we helped raise $13.25 millions of dollars for Web3 startups at a $149 million evaluation— The Odyss3y
For over 9 months in 2023, we’ve had the privilege of collaborating with The Odyss3y — an accelerator and venture fund dedicated to supporting emerging crypto startups. Odyss3y provides consulting services and funding, offering up to $100,000 in direct investments and $5+ million through their partners. This assistance goes beyond mere financial aid, encompassing networking opportunities in webinars, access to cutting-edge technology, strategies for acquiring users and knowledge.
This case study delves into the business processes of investment firms, involving our creation of pitch decks aimed at raising up to $13.25 million for projects worth $149 million. It touches on our production of branding, motion videos, one-pagers, calendars, and websites, offering valuable insights for company owners and startups seeking accelerator or venture fund assistance.
**Who is Odyss3y? How accelerators work?**
The Odyss3y is an accelerator — a type of company designed to support early-stage startups by offering educational programs, mentorship, and often initial funding in exchange for a percentage in the company.
Like many accelerators, Odyss3y dedicates a quarter of each year to gathering applications from companies eager to join their program. To attract these applicants, Odyss3y utilizes its extensive expertise, strong industry connections, and substantial funding capabilities, offering up to $100,000 from its own reserves and facilitating access to over $5 million through its network of partners.
To collect applications, we developed a single-screen website for Odyss3y. In this brief period, we also conceptualized Odyss3y’s branding to last throughout its active cohort. Facing stiff competition in the investment firm industry, particularly from well-known entities like Binance and Kucoin, we scrutinized their commercial-focused approaches. Opting for a different route, we chose to represent Odyss3y as a journey.
All accelerator participants embark on a true odyssey, a journey towards success. By using mysterious digital landscapes and craters, we were able to create an atmosphere of venturing into the new and unexplored, yet incredibly enticing. This concept of travel became the cornerstone of our branding, aiming to reflect the path that Odyss3y promises to its startups, distinguishing it from the conventional commercial imagery in the industry.
**The Marketing Strategy of Odyss3y**
The primary goal of Odyss3y was to attract the most ambitious startups with the strongest and most impressive creators. Odyss3y achieved this by hosting educational online lectures in the Web3 industry, covering everything from marketing to technical and mathematical details.
And we helped with the designs, compiling over 12 lectures for them. Given the large number of presentations, we even created a PDF calendar to help manage this complex path.
This PDF was then shared in Telegram chats and pinned, helping to maintain structure and organization.
Founders’ participation in these lectures was a clear indicator of their commitment to their startups, providing a favorable impression for investors and other builders.
**Fullfillment in Odyss3y**
After receiving a large number of applications, the top experts from Odyss3y, who are well-versed in the industry, select the best projects and invite them for mentorship in a cohort — a group of companies that grow together.
> Historically, the term ‘cohort’ referred to a tenth of a legion in ancient Rome.
During their time in the accelerator, the startups learn and develop their product alongside mentors who have already walked this path. This process can be lengthy and is usually confidential.
At the end of the cohort, each startup faces the Demo Day — the most crucial event for them. On Demo Days, startups present their achievements to an audience of investors and other builders.
The aim of the Demo Day for startups is to help them secure additional funding and expand their network. While Odyss3y can invest up to $100,000, their partners (which we also designed) could allocate up to $5 million or more quarterly, which also serves as a significant attraction.
We were tasked with creating one comprehensive pitch deck for eight companies within the accelerator, aiming for a total of $13.25 million, with a combined valuation of $149 million.
We designed the pitch decks to highlight the uniqueness of each participant, but at the same time we wanted to maintain and showcase Odyss3y’s branding. To achieve this visually we used abstract 3D graphics unique for each participant and strongly aligned with Odyss3y’s overall look and feel thus creating a comprehensive graphic system. In terms of the layout, we used the F-pattern to pinpoint investor’s attention and make each slide informative yet digestible.
Each company’s presentation was aimed to be no longer than 1.5 minutes — time deemed sufficient for major investors. Months of preparation, refinements, reviews, and intense effort led up to this moment.
Many companies, as expected, achieved their investment goals. To celebrate these milestones, we designed personalized banners that aligned with Odyss3y’s branding. An example of this success is Kinetex Network, which raised over $2M.
The funds raised by each company varied significantly, often by hundreds of thousands of dollars or even millions. As for our goal of raising $13.25 million, it’s safe to say we came close to achieving it, but the final amount is not disclosed. Here you are able to see all of the companies in the initial [pitch-deck](https://drive.google.com/file/d/1VtDw5rWvvu9yz7e7kDLSVJQwz359RnVP/view) and check for yourself😉 But most importantly, apart from finances, all of them continue to thrive, having received numerous offers and attracting many users — the second most important metric for startups.
**Results**
As of right now, Odyss3y continues to operate. If you are involved in web3, you can submit your company [here](https://odyss3y.typeform.com/application?typeform-source=odyss3y.xyz). By joining, you gain access to connections with founders, valuable knowledge, and secure investments.
Over the course of 3–4 months of collaboration, we created a one-page website, several lectures and documents, one comprehensive pitch deck for 8 companies, and one motion video for a PR campaign. As a result, we came close to raising $13.25 million for companies with a total evaluation of $149 million.

1,668,471 | Applications of Data Science in Cybersecurity | The prevalence of security incidents, including malware attacks, zero-day attacks, data breaches,... | 0 | 2023-11-16T11:00:36 | https://dev.to/shivamchamoli18/applications-of-data-science-in-cybersecurity-2gla | datascience, cybersecurity, security, infosectrain | The prevalence of security incidents, including malware attacks, zero-day attacks, data breaches, unauthorized access, etc., has risen significantly in recent years with society's growing reliance on digital technologies and the IoT (Internet of Things). Hackers or attackers use more advanced techniques and tools, such as Artificial Intelligence (AI), to carry out cyberattacks and continuously create new criminal technologies to affect an organization's current security system. Data Science plays a crucial role in cybersecurity and is becoming increasingly important as cyber threats evolve.
## **Cybersecurity Data Science (CSDS)**
Cybersecurity Data Science (CSDS) combines data science and cybersecurity principles to protect organizations and individuals against cyber attacks. It involves data analytics, machine learning, and other advanced techniques to detect and prevent cyber threats in real time. It uses large datasets of network traffic, system logs, and other forms of data to identify anomalies and patterns that may indicate an ongoing cyber attack. It also uses machine learning algorithms to automatically detect and respond to potential threats, minimizing the time it takes for organizations to respond to an attack.
## **How is Data Science Used in Cybersecurity?**
**1. Email Security Threats Detection:**
Email threat detection provides an innovative and efficient method for identifying and managing persistent threats. Sophisticated email security systems incorporate machine learning techniques such as Neural Networks (NNs) to improve the detection and prevention of spam emails and phishing messages.
**2. Automatic Intrusion Detection:**
Scanning the system data for potential intrusions is known as intrusion detection. The automatic Intrusion Detection System (IDS) has been a prominent study field for the past two decades. The IDS software employs multiple machine-learning methods to find network intrusions. It monitors criminal activities on a network or system and protects computer networks against users' unauthorized access.
**3. Securing Users Authentication:**
Data Science plays a crucial role in ensuring the security of user authentication systems. Data scientists use machine learning algorithms and data analysis techniques to detect and prevent unauthorized access to sensitive information.
**4. Network Anomaly Detection:**
Network anomaly detection tools or systems monitor the network to diagnose network anomalies and detect potential threats or attacks that may have driven past the firewall. Network anomaly detection presents machine learning techniques that can aid in combating sophisticated malware attacks and network intrusion.
**5. Data Privacy:**
Data Science can also be used to ensure data privacy and security. Data scientists can analyze data to detect and prevent unauthorized access, ensure data is encrypted and secure, and ensure that data is being used in compliance with regulations and privacy policies.
**6. Advanced Malware Detection:**
Advanced malware detection uses machine learning algorithms to determine patterns and anomalies that may indicate an ongoing attack, allowing organizations to respond to threats quickly and effectively. This includes analyzing executable files, network traffic, and system logs to detect malware attacks and prevent them from causing significant damage.
## **Cybersecurity Data Science with InfosecTrain**
Today, data science is one of the IT industry's most sought-after careers. Cybersecurity Data Science aims to enable organizations to detect, respond to, and quickly prevent cyber-attacks quickly.

In the expansive realms of software craftsmanship, the enchantment woven into the sacred codebases reveals a sublime dance betwixt order and chaos.
Lo, discerning eyes may perceive the chaos within software as an innate manifestation of creativity and boundless exploration. A mystic odyssey through intricate and ever-shifting systems, conjuring decisions and dispelling challenges along the arcane journey. The creative process, though tempestuous at times, is propelled by an unwavering desire to bestow order and unfurl functionality upon a distinct vision.
Yet, in the mystical realms of algorithms and logic, there exists a resolute emphasis on imposing order upon the chaos. Coding conventions, design principles, and the venerable scrolls of ancient best practices serve as the formidable staff and incantation, harmonizing the intricate threads of code into a spellbinding symphony.
In essence, the cosmic interplay between order and chaos in software development mirrors the profound arcane discussions surrounding the very nature of creativity, the sorcery of problem-solving, and the delicate equilibrium between the structured runes and the fluid dance of flexibility. | archmage | |

Recently I have been more into taking lessons in DataWars.io (free version) and DataCamp on the Data Engineer track which I paid $120 for a year to complete.
But I have new files to load for the optometry pipeline and I recently successfully containerized the postgres instance and the python pandas pipeline. But the last part of marrying this data pipeline is getting the data to ingest into the postgres DB. All my logs are showing that it's all good! So I've been talking to GPT for such a long time now and I can't figure it out yet. Pretty frustrating, since I'm able to query things that already exist int he postgres instance (that was just copied over from local, where this whole thing was working).
So it works on my local but not on Docker. I'll keep trying. In other news I am working on a basic net worth app, probably do that in a offline desktop version using python, or Flask since I did a Flask tutorial. That's a fun personal project but I have to take a break from the Docker work. Cool stuff but I am frustrated I can't figure it out and neither can GPT! | itech88 |

Though we are strong believers in healthy and respectful debate, we typically try to choose discussions that are positive and avoid those that are overly contentious.
Any folks whose articles we feature here will be rewarded with our Discussion of the Week badge. ✨
Now that y'all understand the flow, let's go! 🏃💨
## The Discussion of the Week
It's my pleasure to highlight Anita's (@anitaolsen) self-reflective discussion thread "[Are You Ashamed of Your Old Code](https://dev.to/anitaolsen/are-you-ashamed-of-your-old-code-3jeb)?"
{% embed https://dev.to/anitaolsen/are-you-ashamed-of-your-old-code-3jeb %}
Anita just recently joined up with DEV, but is already initiating some really thoughtful discussions to get folks talking about their coding origin stories and things they've worked on in the past. Take a look at Anita's profile and you'll notice this common thread throughout their first 3 posts.
Something that I really like about Anita's most recent post is that it encourages folks to open up and talk about their mistakes. In an online world of folks constantly talking down to and one-upping each other, humility is refreshing! I'd much rather see a thread of folks opening up about problems they had & blunders they learned from over folks who seem to know everything and constantly self-promote.
And another thing, it's good for newbies to be able to look through a thread like this and see that other folks out there also started from humble beginnings. It's encouraging and shows them how others have been able to grow. 🌱
As with most discussions, the fun really happens in the comments. I didn't pluck out any particular ones to feature this time around, but if you hop into the post, you can see for yourself. And of course, share your thoughts in the thread while you're at it!
## What are your picks?
The DEV Community is particularly special because of the kind, thoughtful, helpful, and entertaining discussions happening between community members. As such, we want to encourage folks to participate in discussions and reward those who are initiating or taking part in conversations across the community. After all, a community is made possible by the people interacting inside it.
There are loads of great discussions floating about in this community. This is just the one we chose to highlight. 🙂
I urge you all to share your favorite discussion of the past week below in the comments. And if you're up for it, give the author an @mention — it'll probably make 'em feel good. 💚 | michaeltharrington |

There are few several ways to implement CSS styles sheet into HTML document file. The CSS implementation play an important role in the presentation of web pages by applying CSS rules to style the HTML element tags. It defines the visual styles of a HTML markup such as: colors, background-color, padding, margin, font-size and positioning of HTML elements.
We will be looking into three ways of implement CSS into a HTML file which include:
1.Inline CSS
2.Internal CSS or Embedded CSS
3.External CSS
4.@Import CSS.
Inline CSS: An inline CSS is used to apply a unique style to a single HTML element tag. With Inline CSS, we can define the style attribute within a HTML element tag.
Example: Use visual studio code editor or any other editor.
```
<!DOCTYPE html>
<html lang="en">
<head>
<title>Inline CSS</title>
</head>
<body>
<h1 style="color: green; text-align: center;">Hello World!</h1>
<!-- You can add the font-size too and the value of your choice -->
</body>
</html>
```
Here we have been able to apply inline CSS rule using the style attribute
NOTE: An Inline CSS is used to style a specific HTML element and contains the CSS property in the body section attached to the element (within the element tag using the style="" attribute).
For Instants, with the above example you’ll only need to add the style attribute to each HTML tag, without using selectors like an ID, Class or tag element selector.
However, inline CSS in HTML can be useful in some situations. For example, in cases where you don’t have access to CSS files or need to apply styles for a single element only.
Inline CSS is the technique to define the single element with the insert style sheets in an HTML document.
This CSS type is not really recommended, as each HTML tag needs to be styled individually. Managing your website may become too hard if you only use inline CSS.
Advantages of Inline CSS:
You can easily and quickly insert CSS rules to a HTML element tag. That’s why this method is useful for testing or previewing the changes, and performing quick-fixes to your website.
You don’t need to create and upload a separate document as in the external style sheet or internal style sheet.
Disadvantages of Inline CSS:
Adding CSS rules to every HTML element tag is time-consuming and can make your HTML structure messy.
Inline CSS styles cannot be reused anywhere else with other HTML element tag.
Styling multiple elements can be tough and to edit, because they are not stored in a single file.
Internal CSS or Embedded CSS: An internal CSS (or Embedded CSS) can be use to style a single HTML file and its also an effective method of styling a single page.
The internal CSS rules are defined inside the head element tag <head></head> within the style element tag <style></style> and the CSS style rules are all written inside the style tag.
Here is how you can write internal CSS: if you are using vs code, create a HTML file and use Emmet abbreviation to add all the necessary default element tags (the boiler plate), by using shift + 1.
1.Open your HTML file and locate <head> opening tag above the <body> tag.
2.In between the opening element tag and the closing element tag of the head tag add the style tag <style></style>
Example: Use visual studio code editor or any other editor.
```
<!DOCTYPE html>
<html lang="en">
<head>
<title>Internal CSS</title>
<style>
</style>
</head>
<body>
</body>
</html>
```
3.Write your CSS code in between the opening style tag <style> and closing style tag </style>
Your HTML file will look like this:
Example: Use visual studio code editor or any other editor.
```
<!DOCTYPE html>
<html lang="en">
<head>
<title>Internal CSS</title>
<style>
h1{
background-color: aquamarine;
color: white;
text-align: center;
}
p{
background: #000;
color: #fff;
font-size: 20px;
text-align: center;
}
</style>
</head>
<body>
<h1>Hello World!</h1>
<p class="hello">Hello! Welcome</p>
</body>
</html>
```
However, using this style for multiple HTML files is time-consuming as you need to put the CSS rules on every single page of your website.
Advantages of Internal CSS:
You can use class name and id as selectors in this style sheet.
You can select elements by class name, id or element tag name.
Disadvantages of Internal CSS:
Adding the code to the HTML document can increase the page’s size and make it much longer than it should be.
It can be difficult to make change on both HTML part and CSS part at the same time.
Adding the internal CSS style inside the HTML file page sometime is not a good practices, especially when it comes to the image content, video content and others.
External CSS: An External CSS (An external cascading style sheet) is a separate CSS file that can be access through a link tag within the head element tag of the HTML file by creating a link using the link element tag.
Multiple HTML file or web pages can use the same link to access the same style sheet.
The link to an external style sheet is placed within the head tag of the HTML file.
The external style sheet may be written in any text editor but must be saved with a .CSS file extension and must be link inside a HTML file above, inside the head tag.
The external CSS is a more efficient method to write CSS style rules, especially for styling a large website.
By editing one .CSS file, you can change the look of your entire site at once.
The Following steps are how to write and use external CSS: if you are using vs code, create a HTML file and use Emmet abbreviation to add all the necessary default element tags (the boiler plate), by using shift + 1. and add the style rules
1.Create a new .CSS file with the text editor you are using.
2.In between the <head> of your HTML file, add a link element tag with reference to your external .CSS file.
Example: Use visual studio code editor or any other editor.
```
<link rel="stylesheet" href="style.css">
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="style.css">
<title>External CSS</title>
</head>
<body>
<h1 id="hello" class="hello">Hello! Welcome</h1>
<p id="hello" class="hello">Hello! Welcome</p>
</body>
</html>
```
3.By default, link tag comes rel attribute and href attribute but the external CSS styles sheet is link-up inside href attribute like the above example explains. Don’t forget to change style.css with the name of your .CSS file.
Example: Use visual studio code editor or any other editor.
```
<style>
h1{
background-color: aquamarine;
color: white;
text-align: center;
}
p{
background: #000;
color: #fff;
font-size: 20px;
text-align: center;
}
</style>
```
Advantages of External CSS:
The external style sheet is generally use to separate HTML file from CSS style sheet for clean and readable code.
It make your code readable, reusable and organize.
You can use the a single .CSS file to style multiple HTML pages.
Once the CSS code is in a separate file, your HTML files will have a cleaner structure than that of internal CSS and inline CSS.
It is used when you want to make changes on multiple pages at the same time.
Disadvantages of External CSS:
Your pages may not be rendered correctly until the external CSS is linked.
CSS @Import Rules: The CSS import rule is use to import one style sheet into another style sheet. It a convenient way to load additional style sheet into a CSS style sheet.
Example: Google Fonts (Use visual studio code editor or any other editor).
```
<style>
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@100&display=swap');
Body{
font-family: 'Poppins', sans-serif;
}
</style>
```
NOTE: The @import rule must be at the top (inside) of the style sheet. The url(), with a string inside a bracket function represent the location of the resource to import from, i.e we use the url() function to provide a file path or to find the location. | godswill |
1,669,217 | Planning the react pokedex | Having had no prior react experience this project was proving quite a challenge as I wasn't able to... | 0 | 2023-11-17T02:52:16 | https://dev.to/danarkey/planning-the-react-pokedex-5321 | Having had no prior react experience this project was proving quite a challenge as I wasn't able to fall back on past knowledge. From such I found this project the hardest as it was learning something completely new and applying that learning.
Like with all problems though the best way to start is to plan an action of attack.
## What should it do?
As previously stated I had acquired the json file of all competitive pokemon movesets and wanted users to be able to view them save them for later.
Spoiler alert we didn't manage to do that as it was taking me far too long to do the basics.
So the functionality I settled on was that it would be a card like list that featured the full 1010 entries that would load on a 24 card basis.
If a user clicks on a pokemon a modal will appear with its name, stats and the option to add to favourites. If the pokemon is already in favourites the button will change to remove and users can delete its entry. There will be a favourites page where users can view their favourited pokemon.
## Getting started
With the functionality plan sorted it was time to start. First step creating a new react app in my console and installing the relevant node modules such as router for the navigation.
Initially I started building everything out in the App.jsx component which I came soon to realise would be a headache to transfer everything.
I shortly changed to the page approach and had a Pokedex and Favourites page. With the structure sorted it was time to plan the components.
## Components
The components I created for this app were the:
- Header
- Footer
- Individual pokemon cards
- Load more button
- Pokemon modal
- Modal background overlay
- Favourited pokemon modal
I know looking at the list you can see a double up on the modal and then a modal overlay sitting there as well but how I had set up the initial modal made it _much harder_ for that functionality to work for the favourited section.
## Closing remarks
In the next post I'll go over the modals and cards as the header and footer were pretty basic.

1,669,631 | Building a Currency Converter in Django: A Step-by-Step Guide | In today's interconnected world, handling currency conversion is a common requirement for many web... | 0 | 2023-11-17T11:28:17 | https://dev.to/rohitashsingh89/building-a-currency-converter-in-django-a-step-by-step-guide-560f | django, currencyconverter, python, tutorials | In today's interconnected world, handling currency conversion is a common requirement for many web applications. In this tutorial, we will walk through the process of building a simple currency converter using Django, a powerful Python web framework. By the end of this guide, you'll have a functional currency converter that users can interact with.
**Prerequisites**
Before we start, ensure you have the following installed on your system:
- Python
- Django
You can install Django using the following command:
```bash
pip install python
pip install django
```
**Setting Up the Django Project**
Let's begin by creating a new Django project. Open your terminal and run the following commands:
```bash
django-admin startproject currency_converter
cd currency_converter
```
Next, create a new Django app within the project:
```bash
python manage.py startapp converter
```
**Building the Views**
Define the views in the views.py file of the converter app:
```bash
from django.shortcuts import render
import requests
def get_currency_data():
""" Fetch currency data from the API """
url = "https://open.er-api.com/v6/latest/USD"
try:
response = requests.get(url)
response.raise_for_status()
currency_data = response.json()
return currency_data
except requests.exceptions.RequestException as e:
print(f"Error fetching currency data: {e}")
return None
except ValueError as e:
print(f"Error decoding JSON response: {e}")
return None
def index(request):
currency_to = "USD"
result = None
if request.method == "POST":
try:
amount = float(request.POST.get('amount'))
currency_from = request.POST.get("currency_from")
currency_to = request.POST.get("currency_to")
except (ValueError, TypeError):
result = "Invalid input"
else:
url = f"https://open.er-api.com/v6/latest/{currency_from}"
try:
response_data = requests.get(url).json()
if "result" in response_data and response_data["result"] == "success":
rates = response_data.get("rates", {})
ex_target = rates.get(currency_to)
if ex_target is not None:
result = "{:.2f}".format(ex_target * amount)
else:
result = "Currency not found"
else:
result = "Error fetching exchange rates"
except requests.exceptions.RequestException as e:
result = f"API request failed: {e}"
context = {
"result": result,
"currency_to": currency_to,
"currency_data": get_currency_data()
}
return render(request, "index.html", context)
```
**Creating Templates**
Create two HTML templates: base.html
```bash
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

### What is WebRTC?
WebRTC is an open-source project that provides web browsers and mobile applications with real-time communication via simple application programming interfaces (APIs). It empowers developers to create robust, real-time communication applications without the need for plugins or third-party software.
### Core Components:
#### **getUserMedia API: 📷**
The `getUserMedia` API is the gateway to accessing a user's camera and microphone. It prompts the user for permission and returns a media stream that can be used for various real-time communication scenarios.
```javascript
navigator.mediaDevices.getUserMedia({ video: true, audio: true })
.then(stream => {
// Use the stream for video and audio
})
.catch(error => {
console.error('Error accessing media devices:', error);
});
```
#### **RTCPeerConnection: 🔗**
`RTCPeerConnection` establishes and manages the connection between peers, handling the negotiation and transfer of audio, video, and data streams. It employs a series of protocols to ensure a secure and reliable connection.
```javascript
const peerConnection = new RTCPeerConnection();
// Add local stream to the connection
peerConnection.addStream(localStream);
// Set up event handlers for various connection events
peerConnection.onicecandidate = event => {
if (event.candidate) {
// Send the candidate to the remote peer
}
};
```
#### **RTCDataChannel: 📤📥**
`RTCDataChannel` allows for bidirectional communication of arbitrary data between peers. This is particularly useful for scenarios where additional data needs to be transmitted alongside audio and video streams.
```javascript
const dataChannel = peerConnection.createDataChannel('myDataChannel');
dataChannel.onopen = () => {
// Data channel is open and ready to use
};
dataChannel.onmessage = event => {
// Handle incoming messages
};
```
## Chat Application 🎥💬
### HTML (index.html):
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>WebRTC Video Chat</title>
</head>
<body>
<video id="localVideo" autoplay></video>
<video id="remoteVideo" autoplay></video>
<script src="app.js"></script>
</body>
</html>
```
### JavaScript (app.js):
```javascript
const localVideo = document.getElementById('localVideo');
const remoteVideo = document.getElementById('remoteVideo');
navigator.mediaDevices.getUserMedia({ video: true, audio: true })
.then(localStream => {
localVideo.srcObject = localStream;
const peerConnection = new RTCPeerConnection();
// Add local stream to the connection
peerConnection.addStream(localStream);
peerConnection.onicecandidate = event => {
if (event.candidate) {
// Send the candidate to the remote peer
}
};
// Create offer and set local description
peerConnection.createOffer()
.then(offer => peerConnection.setLocalDescription(offer))
.then(() => {
// Send the offer to the remote peer
});
// Handle incoming stream from the remote peer
peerConnection.onaddstream = event => {
remoteVideo.srcObject = event.stream;
};
})
.catch(error => {
console.error('Error accessing media devices:', error);
});
```
## Tips 🛠️
1. **Handling Connectivity Issues ⚠️:** Implement robust error handling to manage unexpected disconnections and network fluctuations.
2. **Bandwidth Considerations 🌐:** Optimize media streams based on available bandwidth to ensure a smooth user experience.
3. **Security Best Practices 🔒:** Use secure connections (HTTPS) and implement proper authentication mechanisms to protect against potential security threats.
4. **Cross-Browser Compatibility 🌐:** Test your WebRTC application on various browsers to ensure consistent functionality.
5. **Debugging Tools 🛠️:** Leverage browser developer tools and third-party libraries like `webrtc-internals` for in-depth debugging.
### Usage
1. **Video Conferencing Apps:** Services like Zoom and Google Meet utilize WebRTC for real-time video conferencing.
2. **Live Streaming:** Platforms such as Twitch and YouTube Live leverage WebRTC for low-latency live streaming.
3. **Online Gaming 🎮:** Multiplayer online games leverage WebRTC for real-time communication between players, enhancing the gaming experience.
4. **File Sharing Services 📂:** WebRTC facilitates peer-to-peer file sharing directly in the browser, making it ideal for applications that require secure and efficient file transfers.

1,678,076 | Why PHP? Thoughts… | @robertobutti https://dev.to/robertobutti/why-php-2e4h Read this article; here are some thoughts on... | 0 | 2023-11-25T11:17:40 | https://dev.to/tkx/why-php-thoughts-266j | php | @robertobutti
https://dev.to/robertobutti/why-php-2e4h
Read this article; here are some thoughts on the subject.
PHP will never ever be on par with python because these three reasons:
1. No native SET data structure support, which is a direct proof that php never was designed for data programming. Amazing @krakjoe and friends introduced it only in 2016 in Ds pecl extension, while python have had it from start.
Consider algorithmic problems such as leetcode stuff, php developer would struggle in half of them not thinking data first - with set structure being a solution in half of this half. Famous expression - framework is not the way you code, it is the way you think. Same situation here. Programming language is not the way you code - but how you think as a programmer, what is your approach, etc.
2. No native coroutine/async/await support in php. Same situation, only adopting ReactPHP/Swoole would give you this instrument, although you’ll have to struggle implementing async solutions for common jobs like databases, etc. And core php team never thought of that in the first place, why?
To create python’s FastAPI stuff you’ll have first to invent it with only Swoole being native implementation of the approach, still it is an external library.
3. Multithreading? Forget it. No native support as well. First thing I had to do as a math student 30 years ago was to implement rectangles method multithreadingly. Guess what, you can’t do it in php.
* * *
Funny story is that I never hesitated which language to choose, PHP was there for me right away :)
And I am not trying to start a hate topic. I only think that one should be realistic and aware about cans and cannots with this or that instrument.

Hi everyone!
It's been a long time, I hope you haven't missed me too much 😄
I've been on paternity leave and enjoyed my little Louise 👨🍼😍.
Apparently my absence hasn't slowed down the growth of this newsletter, which has just [passed 30,000 subscribers](https://www.indiehackers.com/product/french-react-newsletter/30-000-subscribers--NkKag3m683I_z7J3TCI)! 🥳️
This is the first time I've taken such a long break (5 weeks), and it's hard to get back at it. You know I like to be exhaustive, but it's impossible for me to read and comment on everything that's happened since the last issue 😅. In short, this email is going to contain a lot of interesting links, but not necessarily commented on. I'll do better next week, I promise!
In the future, I'd like to make this more professional, and publish every single week consistently. I'm [looking for someone to help me](https://thisweekinreact.com/job). If you're interested, please apply (paid).

Neste post vamos explorar o que é o Git e o GitHub, configuração e principais comandos. Este é um tutorial introdutório para que você se familiarize com a ferramenta.
## O que é Git e GitHub?
O Git é um sistema de controle de versão distribuído, projetado para rastrear as alterações realizadas em arquivos ao longo do tempo, permitindo controlar as alterações realizadas em scripts, conjuntos de dados e qualquer outro tipo de arquivo. Ele mantém um histórico completo de todas as modificações, o que ajuda a evitar conflitos e facilita a colaboração entre diferentes pessoas.
O GitHub, por sua vez é uma plataforma baseada na web que hospeda um repositório Git, também oferecendo diversos outros recursos adicionais, e se tornou uma das principais comunidades de desenvolvimento open source.
Ao utilizar o Git você pode se deparar com vários termos, como commit, stage e branches.
Um commit é como se fosse uma foto instatânea das mudanças feitas nos arquivos de um repositório. Cada commit tem uma descrição que ajuda a entender o que foi alterado e é utilizado para rastrear as alterações realizadas no projeto.
O stage é um espaço intermediário entre os arquivos modificados em seu repositório local e o repositório remoto. Quando você faz alterações em seus arquivos, precisa selecionar quais alterações deseja incluir em um commit, é como dizer ao Git quais mudanças você deseja incluir na próxima “foto”. A ação de selecionar essas alterações e prepará-las para adicionar ao commit é chamada de “staging”.
Branches(ou ramos) são cópias separadas do projeto e permitem que você trabalhe em diferentes partes do projeto sem afetar o código principal. É como uma linha de desenvolvimento independente. O ramo principal do projeto, normalmente chamado de “master” ou “main”, contém a versão estável e funcional do seu projeto, que seria a versão de “produção”. Você pode criar novos ramos para trabalhar em novos recursos (features) ou correções de bugs específicos, isolando as mudanças até que estejam prontas para serem incorporadas ao ramo principal, o que facilita o trabalho em equipe e a organização das alterações.
A forma como as branches são criadas varia de equipe a equipe. Uma prática muito comum é que a branch principal (master/main) contenha a versão de produção mais recente e por isso seja intocável até o lançamento da próxima versão. Então a partir da branch main, cria-se uma branch “dev”, que se torna a branch principal de desenvolvimento. Sendo assim, cada membro responsável por uma correção de bug ou adição de uma nova feature deve criar a sua branch individual a partir da branch “dev” e realizar as suas alterações no código apenas dentro de sua branch. Quando a alteração da branch individual é finalizada, é criado um pull request, que é a solicitação de que o código da sua branch individual seja incorporado(mergeado) à branch “dev”. Ao final do ciclo de desenvolvimento, a branch “dev” é incorporada à branch “main” para que seja disponibilizada a nova versão do produto.
Não se preocupe se você não conseguir entender todos esses conceitos em um primeiro momento, isso é algo que normalmente absorvemos com a prática. No tutorial desta publicação não vamos trabalhar com várias branches, porque o objetivo aqui é que você tenha um primeiro contato e se familiarize com a ferramenta. Branches e outros conceitos serão aplicados com maior profundidade em publicações futuras.
## Configuração
Primeiramente, crie uma conta no GitHub, caso ainda não tenha.
O próximo passo é configurar o [Git](https://git-scm.com/), para isso, é necessário fazer o [download](https://git-scm.com/downloads) e instalação em sua máquina, acessando o site oficial do Git e seguindo as instruções específicas para o seu sistema operacional.
Após a instalação, é necessário realizar uma configuração inicial, definindo o nome de usuário e endereço de e-mail. Crie uma nova pasta na sua máquina e adicione um arquivo de texto qualquer para enviar para o repositório do GitHub (você pode também utilizar uma pasta já criada com os códigos que deseja enviar para o GitHub ao invés de criar uma nova), abra o terminal a partir da nova pasta criada (ou o Git Bash se você utiliza o Windows). Um jeito fácil de fazer isso se você utiliza o Windows é clicar com o botão direito do mouse (clicar em “Mostrar mais opções”, se utilizar Windows 11) e selecionar a opção “Git Bash Here”.
Execute os comandos a seguir substituindo o conteúdo dentro das aspas pelas suas informações utilizadas para criar a conta no GitHub:
```
git config --global user.name "Seu username"
git config --global user.email "seu-email@example.com"
```
## Enviando o conteúdo local para o repositório remoto do GitHub
Crie um novo repositório no GitHub e copie a url do repositório:
Para conectar o repositório local (a pasta na sua máquina) com o repositório remoto (criado no GitHub) utilize os comandos a seguir:
```
git init # inicializa o repositório
# criando uma ligação entre o repositório local e repositório remoto
git remote add origin "a url que você copiou ao criar o repositório"
```
Agora que já foi criada essa conexão, você já pode enviar o conteúdo do seu repositório local (da pasta no seu computador) para o repositório remoto.
```
git status # compara os arquivos do repositorio local com o repositorio remoto
# observe que aparecem todos os arquivos/pastas que existem no repositório local
# porque eles ainda não estão disponiveis no GitHub
```
Para adicionar todos os arquivos ao commit utilize o comando a seguir:
```
git add .
# se você quiser enviar apenas um arquivo específico,
# especifique o nome do arquivo. Por exemplo:
# git add teste.txt
```
Você pode verificar o que foi enviado para o stage. Os arquivos presentes no stage aparecem após Changes to be commited: (use “git rm — cached <file>…” to unstage) .
```
git status
```
Para criar o commit e adicionar uma mensagem para identificá-lo, utilize o comando a seguir:
```
git commit -m "mensagem descritiva"
# exemplo:
# git commit -m "first-commit"
```
Para simplificar, e como esse repositório não é utilizado por outra pessoa, vamos enviar as alterações para a branch master, que é a branch principal. Em projetos reais não devemos enviar diretamente à branch master.
Para enviar as alterações utilize o comando a seguir:
```
git push origin master
```
Após enviar os arquivos, você pode usar o comando “git status” para verificar se ainda há arquivos no repositório local que podem ser enviados ao repositório remoto. Nesse caso não há, pois aparece a mensagem “nothing to commit, working tree clean”.
Atualize a página no seu repositório e você poderá ver que o conteúdo foi enviado com sucesso para o repositório remoto.

Firefox took a while, but on December 19, 2023 it was finally ready 👏🏽👏🏽👏🏽.
The `:has()` pseudo class is very useful and opens up a lot of new possibilities. You can now finally style the parent if it contains certain children. It's a feature I've wanted since the beginning of my coding journey 🤩.
Here is what the selector :has() to offer (pun ... 😏).
```css
/* parent section has a specific element, ul */
section:has(ul) {
background: red;
}
/* parent section both elements, h1 and ul */
section:has(h1):has(ul) {
background: hotpink;
}
/* parent section has either or both elements, h2 and or p */
section:has(h2, p) {
background: lightblue;
}
/* parent section does not have h3 element */
section:not(:has(h3)) {
background: yellow;
}
/* h3 which is followed by a p */
h3:has(+ p) {
background: limegreen;
}
/* section has an input that is checked, then the label gets bold */
section:has(input:checked) label {
font-weight: 900;
}
section:has(> form) {

1,708,394 | Use tailwind within atomic design methodology | original:... | 0 | 2023-12-26T07:17:02 | https://dev.to/zhangzewei/use-tailwind-within-atomic-design-methodology-1bi8 | tailwindcss, css, react | > original: https://markzzw.gitbook.io/zewei-zhangs-minds/core-mind/use-tailwind-in-atomic-design-methodology
Tailwind CSS has gradually become the preferred style processing solution in front-end development. Its simple integration and flexible configurability make it gradually occupy a higher position in front-end development. However, with the use of Tailwind CSS, many front-end developers have also experienced discomfort. Too many classnames cause the code to look untidy, and in the case of complex styles, writing Tailwind CSS is very complicated, which is not conducive to maintenance, so can the above problems be solved by following the theory of atomic components when using Tailwind CSS?
## Atomic Component
Before discussing how to combine atomic components and Tailwind CSS, let's take a look at the atomic component methodology, which divides pages into the following five levels.
1. Atoms
For the definition of the atom as the smallest non-divisible component in the design system, then we should split the web page should be the corresponding html native tag with the corresponding style, that is, input/h1/button and other components, such components can not be split again, and can be used independently.
2. Molecules
A molecule is defined as a component of the design system composed of atomic components, such as a search box with a search button, avatar, card, etc
3. Organisms
An organization is defined as a component composed of atoms and molecules in the design system. Such components generally have certain business capabilities, such as tab components, datepicker components, and list components
4. Templates
The template is defined as a high-reuse interface without data composed of atoms, molecules, and organizations in the design system, such as the table page of the background management system, which has high reuse.
5. Pages
The definition of the page is that after the template is filled with data, the real page is displayed, also known as a high-fidelity page.
Each level is pieced together from the previous levels to form the final page. In this methodology, the main thing is to find atomic components. The following figure helps us to label the atomic components well (native Html elements).
## Atomic Component fit with Tailwind CSS
The page is made up of basic components. The atomic component methodology is not to split the page components as small as possible, but to form molecular components through atomic components and organize components, and then build pages through page templates, which is a process from small to large.
In the development methodology of atomic components, we need to clearly identify which Atomic components are, and then modify the atomic components. Tailwind CSS is just the methodology of Atomic CSS, turning the miscellaneous css styles into a single css attribute.
This solves the problem of hard-to-read html code with a lot of classnames in the code, which is to wrap atomic components and then use atomic components to compose molecular components.
This code is an example of the official website, we will use this example to refactor to show how to do the atomic component.
```jsx

</div>
}
```
This code looks messy and difficult to maintain, and we will look for the atomic components that need to be encapsulated.
### Button componenet
`Button component` is the most common component that we can extract.
So we can do a simple encapsulating.
```tsx
import { ButtonHTMLAttributes } from "react"
type ButtonVariant =
| 'filled'
| 'outlined'
interface ButtonProps extends ButtonHTMLAttributes<HTMLButtonElement> {
variant: ButtonVariant;
}
export default function Button(props: ButtonProps) {
const {
type,
variant,
className,
children
} = props;
const variantClassNames: {[key: string]: string} = {
filled: 'bg-black text-white',
outlined: 'border border-slate-200 text-slate-900'
}
return <button
className={`h-10 px-6 font-semibold rounded-md ${variantClassNames[variant]} ${className}`}
type={type}>
{children}
</button>
}
```
then we can use it as.
```jsx
function ShoppingCard() {
return ...
<div className="flex-auto flex space-x-4">
<Button variant="filled">Buy now</Button>
<Button variant="outlined"> Add to bag</Button>
</div>
...
}
```
### Icon component
Also `svg` can been encapsulated as an atomic component.
```tsx
interface IconProps {
size?: number
}
export default function HeartIcon (props: IconProps) {
const { size = 20 } = props;
const rate = size / 20;
return <svg style={{ transform: `scale(${rate})` }} width='20' height='20' fill="currentColor" aria-hidden="true">
<path
fillRule="evenodd"
clipRule="evenodd"
d="M3.172 5.172a4 4 0 015.656 0L10 6.343l1.172-1.171a4 4 0 115.656 5.656L10 17.657l-6.828-6.829a4 4 0 010-5.656z"
/>
</svg>
}
```
### Radio component
We can find out the `Radio component`, so we need to encapsulate the `<input type="radio" />`
```tsx
import { InputHTMLAttributes } from "react";
interface RadioProps extends InputHTMLAttributes<HTMLInputElement> {
label: string;
}
export default function Radio(props: RadioProps) {
const { label, name, value, checked, className, onChange } = props;
return <label className="relative cursor-pointer" htmlFor={label}>
<input
className="sr-only peer"
type="radio"
id={label}
value={value}
name={name}
checked={checked}
onChange={onChange}
/>
<div
className={`min-w-[36px] min-h-[36px] p-2 rounded-lg flex items-center justify-center text-slate-700 peer-checked:font-semibold peer-checked:bg-slate-900 peer-checked:text-white ${className}`}
>
{label}
</div>
</label>
}
```
then we can use it like this.
```jsx
function ShopingCard() {
const sizeList = [
'XS', 'S', 'M', 'L', 'XL'
];
const onSizeChange = (event: ChangeEvent<HTMLInputElement>) => {
setCurrentSize(event.target.value);
}
const [currentSize, setCurrentSize] = useState(sizeList[0])
return (
...
<div className="space-x-2 flex text-sm">
{
sizeList.map(size => <Radio
key={size}
name="size"
value={size}
label={size}
checked={currentSize === size}
onChange={onSizeChange}
/>)
}
</div>
...
)
}
```
According to the atomic table, we have completed the encapsulation of part of the `Form atomic components` above. Next, we will identify the types of other atomic components.
### Typography component
Document sections
```tsx
import { PropsWithChildren } from "react";
interface TypographyProps extends PropsWithChildren {
className?: string;
variant: 'h1' | 'h2' | 'h3' | 'h4' | 'h5' | 'h6' | 'lead' | 'paragraph'
}
interface TextProps extends PropsWithChildren {
className?: string;
}
export default function Typography(props: TypographyProps) {
const { variant, children, className } = props;
const baseClassNames = 'block antialiased tracking-normal font-sans font-semibold';
const typographies = {
h1: (p: TextProps) => <h1 className={`${baseClassNames} text-5xl leading-tight ${p.className}`}>{p.children}</h1>,
h2: (p: TextProps) => <h2 className={`${baseClassNames} text-4xl leading-[1.3] ${p.className}`}>{p.children}</h2>,
h3: (p: TextProps) => <h3 className={`${baseClassNames} text-3xl leading-snug ${p.className}`}>{p.children}</h3>,
h4: (p: TextProps) => <h4 className={`${baseClassNames} text-2xl leading-snug ${p.className}`}>{p.children}</h4>,
h5: (p: TextProps) => <h5 className={`${baseClassNames} text-xl leading-snug ${p.className}`}>{p.children}</h5>,
h6: (p: TextProps) => <h6 className={`${baseClassNames} text-lg leading-relaxed ${p.className}`}>{p.children}</h6>,
lead: (p: TextProps) => <p className={`${baseClassNames} text-base font-normal leading-relaxed ${p.className}`}>{p.children}</p>,
paragraph: (p: TextProps) => <p className={`${baseClassNames} text-sm font-normal leading-relaxed ${p.className}`}>{p.children}</p>,
}
return typographies[variant]({
className,
children
});
}
```
in this component we can see the classname is a little heavy, Tailwind CSS provides `@apply` decorator, so we can name classname as it's meaning.
```css
.base-font {
@apply block antialiased tracking-normal font-sans font-semibold;
}
.heading1 {
@apply text-5xl leading-tight;
}
.heading2 {
@apply text-4xl leading-[1.3];
}
.heading3 {
@apply text-3xl leading-snug;
}
.heading4 {
@apply text-2xl leading-snug;
}
.heading5 {
@apply text-xl leading-snug;
}
.heading6 {
@apply text-lg leading-relaxed;
}
.lead {
@apply text-base font-normal leading-relaxed;
}
.paragraph {
@apply text-sm font-normal leading-relaxed;
}
```
---
```tsx
import { PropsWithChildren, createElement } from "react";
import './style.css'; // import style
interface TypographyProps extends PropsWithChildren {
className?: string;
variant: 'h1' | 'h2' | 'h3' | 'h4' | 'h5' | 'h6' | 'lead' | 'paragraph';
}
export default function Typography(props: TypographyProps) {
const { variant, children, className } = props;
const headingElements = ['h1' , 'h2' , 'h3' , 'h4' , 'h5' , 'h6'];
const typographiesClassName = {
h1: 'heading1',
h2: 'heading2',
h3: 'heading3',
h4: 'heading4',
h5: 'heading5',
h6: 'heading6',
lead: 'lead',
paragraph: 'paragraph'
};
return createElement(
headingElements.includes(variant) ? variant : 'p',
{ className: `base-font ${typographiesClassName[variant]} ${className}` },
children
);
}
```
### Card
Group content
```tsx
import { HTMLAttributes } from "react";
interface CardProps extends HTMLAttributes<HTMLDivElement> { }
export default function Card(props: CardProps) {
const { children, className } = props;
return <div className={`flex font-sans shadow-md p-2 rounded-xl overflow-hidden ${className}`}>
{children}
</div>
}
```
### Final ShoppingCard
In the end, our shopping card code became easier to maintain and read than before, and there were actually some small components that could be separated, such as dividers and pictures.
```tsx
function ShoppingCard() {
const sizeList = [
'XS', 'S', 'M', 'L', 'XL'
];
const onSizeChange = (event: ChangeEvent<HTMLInputElement>) => {
setCurrentSize(event.target.value);
}
const [currentSize, setCurrentSize] = useState(sizeList[0]);
return (
<div className="flex items-center justify-center h-screen">
<Card>
<div className="flex-none w-48 relative">
<img
src="https://www.tailwindcss.cn/_next/static/media/classic-utility-jacket.82031370.jpg"
className="w-full h-full object-cover"
loading="lazy"
/>
</div>
<form className="flex-auto p-6">
<div className="flex flex-wrap">
<Typography variant="h6" className="flex-auto text-slate-900" >Utility Jacket</Typography>
<Typography variant="h6" className="text-slate-500" >$110.00</Typography>
<Typography variant="lead" className="text-slate-700 mt-2 w-full" >In stock</Typography>
</div>
<div className="flex items-baseline mt-4 mb-6 pb-6 border-b border-slate-200">
<div className="space-x-2 flex text-sm">
{
sizeList.map(size => <Radio
key={size}
name="size"
value={size}
label={size}
checked={currentSize === size}
onChange={onSizeChange}
/>)
}
</div>
</div>
<div className="flex space-x-4 mb-6 text-sm font-medium">
<div className="flex-auto flex space-x-4">
<Button variant="filled">Buy now</Button>
<Button variant="outlined"> Add to bag</Button>
</div>
<Button variant="outlined" className="px-2.5">
<HeartIcon size={24} />
</Button>
</div>
<Typography variant="paragraph" className="text-slate-700" >
Free shipping on all continental US orders.
</Typography>
</form>
</Card>
</div>
)
}
```
There are also corresponding instructions in the official website, how to do the splitting of components.
With the separation of Atomic components, the patchwork page will become intuitive and clear, which is the combination of Atomic Component and Atomic CSS, one is the atomic of logic level and the other is the atomic of style level, in this way can truly achieve the Atomic methodology.

1,708,866 | Provide the best Error Handling for your API | Error Handling in REST API REST API provides a public/private interface to interact with a... | 0 | 2024-01-09T10:29:14 | https://dev.to/woovi/provide-the-best-error-handling-for-your-api-43hn | ## Error Handling in REST API
REST API provides a public/private interface to interact with a system.
Even though you provide good OpenAPI documentation, a type-safe SDK, you can't avoid APIs being used wrong.
There are also situations where even when using the API in the right way, you can get some unexpected or expected errors.
## HTTP Status Code
We can use the HTTP Status Code to provide some common errors that happen to all APIs, here is a list of a few of them:
- 2xx - successful response
- 200 - success
- 3xx - redirections responses
- 301 - redirect
- 4xx - client error responses
- 400 - bad request
- 401 - Unauthorized
- 403 - Forbidden
- 5xx - server error responses
- 500 - internal server error
Return a 2xx status code when the request is a success.
Return a 3xx status code when the server redirects to another endpoint.
Return a 4xx status code when the client used the API in the wrong way.
Return a 5xx status code when the server behaves in unexpected ways.
A 4xx usually means a bug in the client code that is consuming the API.
A 5xx usually means that the server has a bug.
Check more status code here: [Status Code](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status)
## When the status code is not enough
When a client receives a 4xx error, they want to know why they received that error.
A simple approach would be to return an `error` field in the response payload. Example:
```jsx
{
"error": "Pix Key not found"
}
```
The problem with this approach is that uses a pure string for the error. A pure string is good enough for a human to read the error, but not for machines.
## Problems Details and Error Codes
To solve this problem, and provide good errors for machines.
We have the [Problem Details for HTTP APIs](https://www.rfc-editor.org/rfc/rfc7807) that defines a standard for Errors on API.
Below is an example of the error output:
```jsx
{
"type": "https://api.woovi.com/errors/pix-key-not-found",
"title": "Pix Key not found",
"detail": "The Pix Key is not registered in a payment institution",
"instance": "/alias/e553cee3-b2d2-498c-8a56-26249b797b92",
"status": 400
}
```
If you want to write a client that handles the pix key not found error differently, you can just check the `type` field of the error.
## Errors that should be Error Codes
Based on our experience, you need Error codes for errors that are expected to happen even though everything is fine.
For instance, we have an API that enables users to send an Instant Payment (Pix) payment to a Pix Key. This API has some known expected errors that can happen:
- pix key not found
- not enough balance
- payment rejected
For each of these errors, our users need to handle them in different ways.
## Summary
To create a great API, you need to think carefully about how you handle error handling. A good error detail or experience is the difference that will make your user integrate with your API or just give up.
A good error on the API will also reduce support requests.
A good and reliable API will make onboarding faster, increase the conversion rate, and reduce churn.
A great API is good for business.

Below is the list of different SDLC models:
1. Waterfall Model
2. V-Model
3. Incremental Model
4. RAD Model
5. Iterative Model
6. Spiral Model
7. Prototype Model
8. Agile Model
**STLC and it's Stages:**
STLC (Software testing life cycle) is sequence of specific tasks that are carried out in an order to evaluate the functionality of a software application and ensure that the application is defect free and validate that the business criteria is met.
The different stages of STLC are:
1. Requirement analysis:
This is the first phase of STLC life cycle, in this phase the testing team analyses and understands the client requirements and interacts with them incase more information is required to understand in detail about the application's functionality. In this phase the testing team prepares requirement traceability matrix and identifies the environment to execute the test cases.
2.Test Planning:
In this phase, Senior QA managers determine the test plan strategy, efforts, and cost estimates for the project. They also decide on resources, test environment, limitations, and the testing schedule.
3.Test case development:
In this phase the team comes up with all possible scenarios covering both positive and negative test cases in order to test the application
4.Test execution:
In this phase the team executes the test cases and logs defects based on the expected and actual results and verifies the bug fixes.
5.Test closure:
This is the last phase of STC where the team reviews test results, prepares test summary reports and provides QA sign off.
**List of potential risk factors to consider for a web-based application:**
1. Injection:
Injection or SQL injection is a type of security attack in which the malicious attacker inserts or injects a query via input data (as simple as via filling a form on the website) from the client-side to the server. If it is successful, the attacker can read data from the database, add new data, update data, delete some data present in the database, issue administrator commands to carry out privileged database tasks, or even issue commands to the operating system in some cases.
2.Sensitive Data Exposure:
As the name suggests, this means that sensitive data stored is leaked to malicious attackers. This information can include personal data like name, address, gender, date of birth, personal identification numbers like Aadhaar card number or SSN, etc., financial data like account number, credit card numbers, health-related information, etc. This can result in a monetary loss if the attacker uses the financial information of users to carry out online payments (in most cases to cryptocurrency), identity theft, and reputation loss.
3.Using Components with Known Vulnerabilities
Most websites today depend on component-heavy development patterns, which means that in some cases it is possible that the development teams do not even know the internal working of the component. This means, if the component used is itself vulnerable to threats due to some broken code, incorporating it with your application can induce threat vectors as well. This also comes if you’re using older versions of the components or nested dependencies.
**Difference between QA and QC:**
Quality Assurance (QA):
- It focuses on providing assurance that the quality
requested will be achieved.
- The aim of quality assurance is to prevent defects.
Quality Control (QC)
- It focuses on fulfilling the quality requested.
- The aim of quality control is to identify and act on fixing
the defects.
**Difference between Manual and Automation testing:**
MANUAL TESTING:
- In manual testing, the test cases are executed by the human
tester.
- Manual testing is time-consuming.
- Manual testing doesn’t use frameworks.
- Manual testing is not reliable due to the possibility of
manual errors.
- There is no need for programming knowledge in manual
testing.
AUTOMATION TESTING:
- In automated testing, the test cases are executed by the
software tools.
- Automation testing is faster than manual testing
- Automation testing uses frameworks like Data Drive, Keyword.
- Automated testing is more reliable due to the use of
automated tools and scripts.
- Programming knowledge is a must in case of automation
testing as using tools requires trained staff.

1,709,646 | The Simplest Beginners Guide On Switching To Linux | Linus Torvalds introduced Linux 0.01 in 1991, a rough 30 years after Bell Labs introduced Unix as a... | 0 | 2023-12-27T14:06:29 | https://blog.neverinstall.com/the-simplest-beginners-guide-on-switching-to-linux/ | Linus Torvalds introduced Linux 0.01 in [1991](https://www.geeksforgeeks.org/linux-history/?ref=blog.neverinstall.com), a rough 30 years after Bell Labs introduced Unix as a multi-user, multi-purpose operating system used primarily across science and research functions. If Windows was introduced to grant access to a non-technical user the comfort and utility of a computational machine, Linux made it insanely easier for developers to have a fully customisable interface where they can work in more uniquely developed environments, unburdened by the prices and affordability of more marketed softwares. It’s also considered notoriously complicated to get a hang of within the first few tries, especially without guided assistance from a whole bunch of forums, blogs and tutorials. [Neverinstall](https://neverinstall.com/?utm_source=blog&utm_medium=blog&utm_campaign=blog), which is built out of Debian OS, a linux distribution, optimises this entire process with the help of the in-built AI assistant that can fasten up your switch by providing highly contextualised assistance, command prompts, quick fixes, remedies, detailed how-tos, and more.
##
Introduction to Linux
Linux originally started as an operating system designed for personal computers but has since expanded its usage to various other devices, including servers, mainframe computers, supercomputers, and more. In recent times, Linux has found applications in embedded systems like routers, automation controls, televisions, digital video recorders, video game consoles, and smartwatches.
One of Linux's most significant achievements is its role in the Android operating system. Android is built upon the Linux kernel and is commonly found on smartphones and tablets. Thanks to Android's widespread adoption, Linux boasts the largest installed base among all general-purpose operating systems.
In the world of Linux-based operating systems, there's a central component known as the Linux kernel, which acts as the brain of the system, managing things like the CPU, memory, and peripherals.
When it comes to interacting with your computer, think of the desktop environment as the outer layer of your brain, where you do things like thinking, seeing, and feeling. There are many different desktop environments available, such as GNOME, Cinnamon, Mate, Pantheon, Enlightenment, KDE, Xfce, and more. Each of these desktop environments comes with pre-installed programs like file managers, configuration tools, web browsers, games, and more, just like different parts of your brain are responsible for various tasks in your body.
##
Some Interesting Linux Distributions
As Linux gained popularity, it sparked the creation of numerous customised versions of the operating system known as distributions or distros. These distros are like different flavours of Linux, each tailored to specific needs and preferences. Here are some examples of popular Linux [distributions](https://javascript.plainenglish.io/why-i-switched-to-linux-and-why-you-should-too-d124ad791273?ref=blog.neverinstall.com):
Think of Red Hat as a special recipe for Linux. It's designed for businesses and organisations, offering robust support and security features. Red Hat Linux is like a suit and tie version of Linux, ideal for corporate environments.
Debian is a versatile and community-driven distro. It's like a do-it-yourself kit for Linux enthusiasts who want to customise their operating system to their liking. Debian provides a solid foundation that users can build upon. Neverinstall runs on Debian OS!
Ubuntu is a user-friendly distro that aims to make Linux accessible to everyone. It's like the Linux equivalent of a user-friendly smartphone interface. Ubuntu comes with pre-installed software and a polished interface, making it easy for newcomers to dive into the Linux world.
Mint OS is used extensively over home entertainment use, Kali Linux is an advanced linux distribution used for penetration testing, ethical hacking and network security assessments, Gentoo OS can run in a wide range of environments, from embedded systems and virtual containers (LXC, OpenVZ, etc.) through to large cluster machines.
Arch Linux is said to be the best Linux distribution for advanced programmers as it is built on a rolling release model and keeping the system and packages updated is one command away. Arch Linux offers absurd amounts of customizability to its users. A clean installation of Arch doesn’t even include a Desktop Environment or a Window Manager. The user builds their system from the ground up. This approach also makes Arch extremely lightweight because there is no pre-installed bloat on the system, the user has full freedom of what you want and when you want it. Manjaro Linux provides a less complicated version of the same for the people seeking more user-friendliness from their OS. Although security is an often raised issue within the Manjaro Community.
These distributions include the Linux kernel as their core, just like how all cars have engines. Alongside the kernel, they bundle various user-friendly tools and software packages, akin to having different accessories and features in your car.
And the magic lies within the [terminal](https://www.freecodecamp.org/news/i-switched-from-windows-to-linux-here-are-the-lessons-i-learned-along-the-way-434da84ab63f/?ref=blog.neverinstall.com), which allows you to configure, and run your imagination wild. Figuring out your way around is the key to the operation here and will require a fair amount of time and focus, unless you happen to have Neverinstall’s AI on your side.
Linux offers a wide range of command prompts that you can use based on your preferences and needs. Here are a few unique and distinctive Linux command prompts:
-
Bash (Bourne-Again Shell): This is one of the most common and default command prompts in Linux. It's known for its flexibility and extensive features.
-
Zsh (Z Shell): Zsh is a powerful and highly customizable shell with features like advanced tab-completion and theming.
-
Fish (Friendly Interactive Shell): Fish is designed to be user-friendly with auto-suggestions and a clean, easy-to-read syntax.
-
Xonsh: Xonsh combines the syntax of Python with a command prompt, making it an interesting choice for those familiar with Python.
-
Elvish: Elvish is a shell with its own unique scripting language, designed to be more intuitive and user-friendly.
-
Ion: Ion is a shell that focuses on speed and minimalism. It's written in Rust and offers a modern experience.
-
With that overview in mind of how Linux is structured, and what it can offer, let’s look at some of the issues that crop up with switching to a Linux based operating system, and also how we can resolve them.
##
A Smooth Linux Onboarding Experience
Some of the biggest problems encountered while switching to a completely Linux based experience is the time taken to familiarise yourself with the unique command promptings and language used. Neverinstall AI offers a differentiated approach [here](https://www.linuxtechi.com/install-mx-linux-step-by-step/?ref=blog.neverinstall.com), and can hand-hold you through the initial days of research and familiarisation.
[To begin](https://medium.com/@braden.bagu/switching-to-linux-a-simple-guide-for-beginners-5d215a31f570?ref=blog.neverinstall.com) with, back up your data to prevent any unnecessary loss, and create a bootable USB drive with your chosen distribution. You can refer here for a complete step-by-step guide.
Installing and configuring driver packages depending on hardware specifications can also get a little tricky, except our AI has contextual information about the OS that allows it to get you the fastest execution on your immediate requirements. Updates and maintenance is also not on your plate of troubles anymore, as your omnipresent AI handles all the frivolous tasks with single line inputs.
As support and assistance is majorly handled through pooled community resources and finding the exact forum, talking about the same exact problem you are facing can be quite the lengthy process and requires time. Having an assistant on the side dock parse through reviews/debates/discussions or online tiffs can be exactly the breather you need.
Switching to a Linux based OS also implies that you can now run your hardware on even a 2GB RAM system, and combining that with the low latency of Neverinstall, you are guaranteed an insanely speedy workflow without any interruptions from the noise and troubles of the outside world.
Certainly there are some use cases that beats the Linux >> Windows discourse, three specific points highlighting these challenges would be
-
Limited Proprietary Software Support
Many proprietary software applications, such as Adobe Creative Suite, Microsoft Office (without online versions), and some specialised industry software, do not have native Linux versions. While alternatives like GIMP or LibreOffice exist, they may not offer the exact same features and compatibility, which can be a significant hurdle for professionals who rely on specific software tools.
-
Gaming Compatibility
Although Linux gaming has improved over the years, not all Windows games are available for Linux. Popular gaming platforms like Steam have expanded their Linux support, but games relying on DirectX may not work without compatibility layers like Proton. This can be frustrating for gamers who want access to a wide range of titles.
-
Hardware Driver Issues
Linux hardware support is generally robust, but some peripherals and devices may not have full driver support. This can affect hardware functionality, such as specialised printers, graphics cards, or certain Wi-Fi adapters. Users may need to search for or develop custom drivers, which can be complex and time-consuming.
These specific challenges should be considered when contemplating a switch from Windows to Linux, as they can impact your ability to seamlessly transition to the new operating system.

1,708,903 | 5 Things Most Developers Learn Too Late ⌛ | When I look back at my developer career in the last 10 years, going from Junior to Senior level, to... | 0 | 2023-12-27T16:50:49 | https://www.theseniordev.com/blog/5-things-most-developers-learn-too-late | career, productivity, javascript, beginners | When I look back at my developer career in the last 10 years, going from Junior to Senior level, to mentoring over 200+ developers helping them get to the next level…
And if I only had 10 minutes to share with you everything I learned…
I would boil it down to 5 core principles.
Five lessons that will dramatically accelerate your growth as a developer to the next level. Keep on reading because in this article I will give you 10 years of experience wrapped up in a few minutes.
Let’s start with number one…
# 1. Good Things Come To Those Who Persist
Here is a hard pill to swallow for most developers: despite all the magic tips and tricks you’ve been sold, a successful developer career is not built in a few days, weeks, or months.
It is built in years, even decades.
Reaching the top in any field, from sports to art, to software development will take you around a decade. That is 10 years, give or take assuming you do everything correctly (which most people don’t).
Most Software Developers don’t have that kind of long-term thinking when planning their careers. They just go with the flow.
Their careers are a series of ups and downs.
They either work 80 hours a week, trying to do everything at once and get burned out, or quit.
Or they do nothing and are stuck at the same level for years.
Their job might be average. Average is comfortable. So instead of doing something to change their situation, they get distracted.
They waste time binge-watching Netflix or get addicted to video games. Soon they find themselves stuck, with outdated skills or even worse, unemployed.
First 5 years of my career as a developer I suffered from the same vicious cycle.
I always when I would get my sh**t together. Wake up on time, learn something new daily, and improve my skills.
And times when I would crush and burn.
I would spend my weekends demotivated eating Cheetos looking for cheap dopamine shots. Like the latest RPG video game to sink my time into or a Netflix series to re-watch.
There is a problem with this vicious cycle.
The ups are awesome. But the downs are awful. Because they put everything at risk. If you burn out or your health is suffering, you risk quitting being a developer altogether.
**Senior Developers look for consistency over speed. **
Because when you manage the downsides, the upsides will come. Steady effort towards a goal beats inconsistency every single time. Small steps every day accumulate to a huge advantage down the road.
# 2. You Do You
In my first years working as a developer, I expected others to do things for me. I expected my boss to promote me. I expected my company to pay for training.
And when it wouldn’t happen I would blame everything but me
Oh, this company is such a shitty place to work for. Oh, my boss is so incompetent. He can’t even see the value I bring to the table.
Or, I would play the victim.
It’s because they don’t like me. It’s because I don’t have a CS degree. It is because I don’t speak the language/ I am an immigrant. Indeed, the world is not a perfect place. In fact, it can be very unfair.
But, no matter how hard you have it, falling into the victim culture won’t improve your condition.
It will give you an excuse and consolation. But, in the long term, it will disempower you.
Because when you focus on the things you cannot change (like your background), you just give away all your power to change your situation.
Taking responsibility for your life gives you the power to change it.
Telling yourself “Where I am in life right now, is all my doing” is something very hard to do. You can easily fall into blaming yourself. But this is not about blaming yourself.
It is about accepting that you have the power to change your circumstances. And you have no choice because no one is coming to save you.
In my case, instead of complaining about how I am underpaid and some other developer had it easier, I started thinking okay, what can I do to change that?
Can I switch jobs?
Can I learn some new skills?
I thought about solutions and execution. I went to conferences. I got mentors. I invested time and money in training. And I stopped comparing myself with anyone.
My life changed 180 degrees when I started looking at myself for solutions.
It is much easier to blame someone else for your life troubles. Taking ownership of one’s situation is one of the best things you can do for your career.

# 3. To Get Golden Eggs, Don’t Kill The Goose
For most of my developer career, I worked long hours, did not do sports, and spent my evenings either playing video games or getting drunk and eating trash food at the pub with my fellow developers.
Coding all day meant I had a very sedentary lifestyle.
Being surrounded by candy and sweets and soda like many developers have access to in their offices did not help at all.
The result?
I looked and felt like trash all day round.
I never got enough rest. My energy levels were low so I would compensate with energy drinks which would make the whole thing even worse.
As developers, we sit on chairs, in front of computers for at least 8 hours a day. That’s a lot. And it is killing you. To be clear, I don’t care about how people look. But we are talking about your health. If you don’t take care of yourself, you won’t even enjoy the fruits of your work.
Make time to go to the gym. Twice or three times a week is enough. Control what you eat. For example, I know that if I buy something I am going to eat it. So I try not to buy any sugary stuff.
For a few years now I have been on a low-carb diet and it works wonders for me.
Taking care of yourself will improve your focus, productivity, and happiness. There is no way you can be happy when you feel sick.
Like Confucius said: "A healthy man wants a thousand things, a sick man only wants one."
One side note: taking care of yourself also means grooming yourself. A lot of developers think "ohh everything is so casual these days" so I can show up to the office or a Zoom call in my pajamas. Yes, you can, but it won’t help you get that promotion. Make sure you have personal hygiene in place.
# 4. Succeed By Design, Not By Accident
Many developers are not happy with the outcome they’ve got in their lives. That’s because most have what I call, opportunistic careers. Jumping from job to job hoping the next one will be better than the last.
And again, if you are in your first three years coding, that’s okay. Get some experience quickly and think about it later.
But you can’t build a career like that.
Some people do, they get lucky, but don’t assume you are those people.
Every day I jump on calls with developers asking them about their goals and vision for the future. And most of them don’t have one.
This is a pity because if you don’t know what you want, you will most likely end up with something you don’t like.
When you have a vision of where you want to go and plan, you can take action to get there. A vision is a guide for your life and career telling you whether the choices you make are good or not.
You might not achieve everything you set out to but, you will have a blueprint to follow. Which is a hell lot better than improvising. Life without a plan is like a race without a finish line, you are just running nowhere.
# 5. Think Small, Stay Small
It might sound cliche, I know. But, probably the most important thing I learned way too late in my career was to believe in myself and to dream BIG.
Maybe it was my background.
Maybe it was the lack of role models growing up.
But for a long time in my developer career, I stopped myself from thinking big. From really going for what I want.
Because deep inside I didn’t think I deserved it.
I remember one day writing in my diary that I wanted to get a 100k job. And deleting that line just after. Telling myself I was crazy and arrogant, and who would pay me that. I am just another developer I told to myself.
The biggest limit to my developer career was giving in to my inner demons.
The doubts and the self-limiting beliefs.
Everything changed when one of my friends, someone that I used to be pretty close with passed away. That moment I realize I will probably get a lot less time than I think in this world, and I better use it.
So I decided to try anyway because hey life is short and you don’t lose much by trying.
I tried thousands of things and most of them went wrong. But every small victory made me believe in myself a bit more, and a bit more. Until today, when I am here making this video for you. And still, I didn’t achieve everything I set out to.
But dreaming a bit bigger than just being a developer in a cubicle writing code was the first step for me to get there. If you are a developer that thinks they have more potential than they think they do, dream big because life is a lot shorter than you think.
Okay, now I have 3 things I want you to do.

No dia 27 de novembro, comecei minha jornada um tanto estranha para quem é de fora do mundo da tecnologia: Comecei a usar o Android (que é um sistema da Google) sem os apps da Google. O quão bizarro ou maravilhoso pode ser usar o sistema do robozinho verde mais privativo? Essas são minhas conclusões:
###Mas afinal, qual o motivo dessa experiência?
O ponto é simples: abra o “My Activity” da sua conta na Google e veja tudo o que você fez. Reconhece aqueles aplicativos que você abriu? Como o Google sabe de tudo isso? Como ele coleta esses dados e pra quê ele usa isso?
Existe uma forma para que a Google pare de coletar meus dados? A resposta é sim, mas exige alguns passos mais avançados. Então basta eu trocar meu sistema operacional, certo? Bem…
Quando o assunto é sistemas operacionais mobile, você deve imaginar em apenas dois nomes: O Android e o iOS (também conhecido como “o do iPhone”). Ambos são muito práticos e são os sistemas que todas as pessoas estão acostumadas a usar no seu dia a dia. Mas existem outros também, embora sejam mais para nichos e usos específicos.A maioria deles são baseados em Linux, como o [Ubuntu Touch](https://ubuntu-touch.io/), o [PureOS](https://pureos.net/) da Librem, [Sailfish OS](https://sailfishos.org/) e o [postmarketOS](https://postmarketos.org/).
Mas uma coisa que esses sistemas alternativos pecam é na comodidade. Vários apps não possuem uma versão para aquele sistema operacional. WhatsApp, Uber, entre outros não existem. Você pode instalar uma camada de compatibilidade do Android, mas envolve processos mais avançados e em casos extremos, é necessário até patchear/recompilar o kernel.
Agora se você usar Android, nem precisa se preocupar com isso. Basta baixar o app e usar. Mas o Google vai continuar coletando dados. É aqui que temos o pulo do gato.
###Segundo ponto: Privacidade sem largar a comodidade
Muitos aplicativos necessitam do Google Play Services, um app da Google que funciona como um conjunto de bibliotecas para os apps funcionarem… Ok, vejamos de outro modo.
Para alguns apps funcionarem, eles necessitam de alguns códigos que só existem no Google Play Services. Acesso a GPS, uso de alguns serviços na nuvem, etc. Sem o Google Play Services, o seu Uber não vai detectar sua localização e seu WhatsApp não vai receber notificação. Você só receberá mensagens quando abrir o app. Bem incoveniente, né?
Para contornar esse problema, existe um substituto ao Play Services: O Projeto MicroG, mantido pelo desenvolvedor alemão Marvin Wißfeld. Essa implementação é de código aberto e não conta com os rastreadores da Google. Existem algumas formas de instalação, mas…
###Terceiro ponto: O sistema funcionaria de forma idêntica ao original. Porém…
Entrando em termos mais técnicos, o que fiz foi: Baixar a variante da [LineageOS](https://lineageos.org/) (sistema operacional baseado no [Android Open Source Project](https://source.android.com/)) chamada [LineageOS for MicroG](https://lineage.microg.org/). Explico mais sobre como fazer isso em um post futuro.
Baixando o LineageOS for MicroG, tudo já vinha configurado. Bastava “flashear” o sistema e tudo certo. E… Foi exatamente isso que aconteceu. Não foi necessário configurar mais nada, só precisei logar minha conta da Google para o YouTube.
A loja de aplicativos não é a Play Store, mas por padrão vem o [F-Droid](https://f-droid.org/): Uma loja de aplicativos Android com o diferencial de ter apenas aplicativos de código aberto. E não, você não encontrará o WhatsApp, por exemplo. Para isso, é necessário o download de outra loja: [Aurora Store](https://auroraoss.com/). Nele, você pode logar em uma conta anônima e usar a Play Store sem rastreio algum. Todos os aplicativos estão lá.
Inclusive, caso queira substituir aplicativos proprietários para código aberto, você pode conferir esse [guia no GitHub](https://github.com/higorslva/foss-android).
Após algumas semanas usando o Android dessa maneira, algumas coisas curiosas aconteciam. App do Uber simplesmente parou de pegar minha localização. Minha cidade não é lá tão grande mas caso eu estivesse em um local desconhecido, teria que usar métodos neandertais para me localizar: Pedir informação.
Da mesma maneira que o Uber me deixou na mão, o WhatsApp parou de receber notificação. Algumas mensagens urgentes eu simplesmente não via pois não tenho costume de abrir o WhatsApp a não ser que eu receba notificação ou queira mandar mensagem pra alguém. Mas notificações não chegavam, o que me forçava abrir o app algumas vezes e me deparar com mensagens de uma hora atrás no limbo.
Como quis me desapegar de aplicativos do Google, usei outros alternativos daquela lista lá. Todos funcionam muito bem e alguns uso até hoje depois da experiência. Mas eu uso bastante meu computador e os serviços da Google funciona tudo pela nuvem. Um texto que escrevi no Google Keep poderá ser acessado depois no meu computador e vice versa. Eu tive que abrir mão disso e foi bem sofrido.
Outro ponto negativo foi que o app que gerencia o MicroG simplesmente não abria mais. Caso eu quisesse adicionar uma nova conta do Google, não poderia. Ligar/desligar algumas funções? Esquece.
###Conclusão: Valeu a pena?
Se você quiser mais privacidade e considera o uso das bibliotecas da Google pelo MicroG, esteja ciente que tem altas chances de que nem tudo irá funcionar. Algumas vezes é necessário apenas marcar uma opção nas configurações, outras nem solução você terá. Não tenho nada contra a Google e uso seus serviços sem problema nenhum.
Na minha experiência houve mais contras do que prós, então não tive problema em voltar a usar meu celular como sempre usei. Inclusive, em um próximo post eu mostro como é meu celular, meus aplicativos e como organizo minha vida digital.
Abraços e se cuidem. | higorslva |
1,709,167 | INTRODUCTION TO CAPL PROGRAMMING. | Hello Readers, My name is Rajesh M, and I work at Luxoft India as a Junior Software Developer.... | 0 | 2023-12-27T04:21:04 | https://dev.to/rajeshm1/introduction-to-capl-programming-j1p | Hello Readers,
My name is Rajesh M, and I work at Luxoft India as a Junior Software Developer. Luxoft has given me several opportunities to work on various projects, which has inspired me to learn the essential processes involved in developing AUTOSAR Modulеs and Add-Ons in INTRODUCTION TO CAPL PROGRAMMING.
**INTRODUCTION**
CAPL is the most used programming language in the automotive world for developing automated tests and simulations. It is the primary programming language for the most powerful CAN tools offered by Vector.
The programming language is based on C/C++ syntax and offers some key features for embedded systems to the programmers. CAPL developers can develop fully automated simulations in CAPL by developing automated test environments for their systems.
**CAPL and the corresponding Vector tools offer:**
- manage test scenarios and all test activities
- event-based functions used in simulations or tests
- interconnections with other PC applications
CAPL is event-driven software, because running a test script or simulation cannot be considered linear execution. The program can switch to another procedure at any time based on three different types of events.
The CAPL browser, where full autotest or autosimulation development is performed, has a very useful text editor for the CAPL program, as well as a CAPL compiler.
A program written in CAPL represents parts or all the behavior of a single network node of a car. For more complex systems and simulations, the programmer can create several different nodes connected to the same CAN bus, each node running its own CAPL software. All nodes can be simulated to check the behavior. Once this is done, the developer can deactivate any bus node and connect it to the real system for testing. In addition to running a generic CAPL program.
most tools also provide other useful functions for testing and debugging embedded systems.
- accurate and easy to use trace window
- bus statistics
- graphic display of sent/received messages and signals
- logging / replay capabilities
Advantages of CAPL Programming:
The system environment can be copied using CAPL, for example by simulating the data traffic of all other network nodes.
1. Node or system behavior using readable English instructions and values instead of hexadecimal values.
2. Event messages, periodic messages, or conditionally repetitive messages.
3. Human events like button presses on the PC keyboard.
4. Timed node or network events.
5. Multiple time events, each with its own programmable function.
6. Normal operation, diagnostic operation, or manufacturing operation.
7. Changes in physical parameters or symbolic values (for example, “ON”, “OFF”).
8. Module and network faults to evaluate a limited operation strategy.
**A CAPL program consists of two parts:**
1. Declare and define global variables
2. Declare and define user-defined functions and event procedures
CAPL Program Organization:
**CAPL programs have three distinct parts:**
1. Global Variable Declarations
2. Event Procedures
3. User-Defined Functions
CAPL Variables:
The data types of variables are integers (dword, long, word, int, byte, char), floating point numbers (floating point and double numbers),
CAN messages (message) and timers (timer or msTimer). All other variables except timers can be initialized in their declarations.
**example:**
variable
{
int msgCount;
message 34 sendMsg = { dlc = 1, byte(0) = 1 }
}
Variables can be initialized after they are declared, in which case you can use either the plain notation or the braces {}. Except for timers, the compiler initializes all variables to their default values (unless otherwise specified: 0).
CAPL allows you to define arrays (arrays, vectors, matrices) analogously to how they are defined in the C programming language.
**Example:**
variable
{
int vector[5] = {1,2,3,4,5};
char progname[10] = “CANoe“;
}
Time events are created using variables of type timer (based on seconds) or msTimer (based on milliseconds). Timer variables are not automatically initialized when the program is started, but must be "set" specifically with the setTimer() function.
**Example:**
variable {
timer delayTimer;
msTimer cycTimer;
}
...
setTimer(delayTimer,3);
setTimer(cycTimer,100);
...
**Declaration of Messages:**
Messages printed by the CAPL program are indicated by the keyword message. The full statement contains the message identifier or, when working with symbolic databases, the message name. For example, the following message can be written to bus output message with an identifier of A (hex) or 100 (dec), or to a message defined in the EngineData database.
**example**
message 0xA m1; // Message declaration (hex)
message 100 m2; // Message declaration (dec)
message EngineData m3; // Symbolic declaration
message * wcrd; // Declaration without Id
...
output(m1); // Transmit message m1
output(m2); // Transmit message m2
output(m3); // Transmit message m3
wcrd.id = 0x1A0; // Define Id...
output(wcrd);
The control data of CAN message objects can be accessed with the following component selectors:
ID Message identifier
CAN Chip number
DLC Data Length Code
DIR Direction of transmission, possible values: RX, TX,
TIME Time point, units: 10 microseconds
**Event Procedures:**
You can use event procedures to respond to the following CAPL events
**React to Changes in Values of Environment Variables**
The "on envVar" event is caused by a change in the value of an environment variable. (Note: Remember that environment variables are only available in CANoe.) The "this" keyword is used with the getValue() function to get the value of an environment variable.
**example:**
on envVar Switch {
int val;
val = getValue(this);
}
**CONCLUSION**
In This Article I have Covered About Introduction to CAPL Programming And its Importance Thank you.

Email notifications are the most common way to keep your users informed about actions taking on your application. Typical notifications include: someone follow you, someone likes your post, someone viewed your content. In this post, we are going to explore how we can create a simple asynchronous email notification system using Next.js, Resend and Trigger.dev.
We will use Next.js as the framework to build our application. We will use Resend to send emails and Trigger.dev to offload and send the emails asynchronously.
## Papermark - the open-source DocSend alternative.
Before we kick it off, let me share Papermark with you. It's an open-source alternative to DocSend that helps you securely share documents and get real-time page-by-page analytics from viewers. It's all open-source!
I would be super happy if you could give us a star! Don't forget to share your thoughts in the comments section ❤️

## Setup the project
Let's go ahead and set up our project environment for our email background notification system. We'll be creating a Next.js app, and set up to Resend, and most importantly, Trigger to handle the asynchronous email notifications.
### Setting up Next.js with TypeScript and Tailwindcss
We'll use `create-next-app` to generate a new Next.js project. We'll also be using TypeScript and Tailwind CSS, so make sure to select those options when prompted.
```bash
npx create-next-app
# ---
# you'll be asked the following prompts
What is your project named? my-app
Would you like to add TypeScript with this project? Y/N
# select `Y` for typescript
Would you like to use ESLint with this project? Y/N
# select `Y` for ESLint
Would you like to use Tailwind CSS with this project? Y/N
# select `Y` for Tailwind CSS
Would you like to use the `src/ directory` with this project? Y/N
# select `N` for `src/` directory
What import alias would you like configured? `@/*`
# enter `@/*` for import alias
```
### Install Resend and React-Email
Resend is a developer-first transactional email service. We'll use it to send emails to our users. `react-email` is a React component library that makes it easy to create beautiful emails.
```bash
npm install resend react-email
```
### Install Trigger
Trigger is a background job framework for TypeScript. It allows you to offload long-running tasks from your main application and run them asynchronously. We'll use it to send emails asynchronously.
The Trigger CLI is the easiest way to set up Trigger in your new or existing Next.js project. For more info, check out [their docs](https://trigger.dev/docs/documentation/quickstarts/nextjs).
```bash
npx @trigger.dev/cli@latest init
```
## Building the application
Now that we have our setup in place, we are ready to start building our application. The main features we'll cover are:
- Setup Resend email
- Write a API route to send email
- Add a Trigger job to make the email sending asynchronous
### #1 Setup Resend email
First, we'll need to set up Resend to send emails. We'll create a new file `resend-notification.ts` in our project and add the following code.
```ts
// lib/emails/resend-notification.ts
import { Resend } from "resend";
import { NotificationEmail } from "@/components/emails/notification";
const resend = new Resend(process.env.RESEND_API_KEY!);
export async function sendNotificationEmail({
name,
email,
}: {
name: string | null | undefined;
email: string | null | undefined;
}) {
const emailTemplate = NotificationEmail({ name });
try {
// Send the email using the Resend API
await resend.emails.send({
from: "Marc from Papermark <marc@papermark.io>",
to: email as string,
subject: "You have a new view on your document!",
react: emailTemplate,
});
} catch (error) {
// Log any errors and re-throw the error
console.log({ error });
throw error;
}
}
```
And the notification email template using `react-email` will look like this:
```tsx
// components/emails/notification.tsx
import React from "react";
import {
Body,
Button,
Container,
Head,
Heading,
Html,
Preview,
Section,
Text,
Tailwind,
} from "@react-email/components";
export default function ViewedDocument({
name,
}: {
name: string | null | undefined;
}) {
return (
<Html>
<Head />
<Preview>See who visited your document</Preview>
<Tailwind>
<Body className="bg-white my-auto mx-auto font-sans">
<Container className="my-10 mx-auto p-5 w-[465px]">
<Heading className="text-2xl font-normal text-center p-0 mt-4 mb-8 mx-0">
<span className="font-bold tracking-tighter">Papermark</span>
</Heading>
<Heading className="mx-0 my-7 p-0 text-center text-xl font-semibold text-black">
New Document Visitor
</Heading>
<Text className="text-sm leading-6 text-black">
Your document was just viewed by someone.
</Text>
<Text className="text-sm leading-6 text-black">
You can get the detailed engagement insights like time-spent per
page and total duration for this document on Papermark.
</Text>
<Section className="my-8 text-center">
<Button
className="bg-black rounded text-white text-xs font-semibold no-underline text-center"
href={`${process.env.NEXT_PUBLIC_BASE_URL}/documents`}
style={{ padding: "12px 20px" }}>
See my document insights
</Button>
</Section>
<Text className="text-sm">
Cheers,
<br />
The Papermark Team
</Text>
</Container>
</Body>
</Tailwind>
</Html>
);
}
```
### #2 Write a API route to send email
Now, we have our email template ready. We can use it to send emails to our users. We'll create a serverless function that takes the `name` and `email` of the user and sends them an email using the `sendNotificationEmail` function we created earlier.
```ts
// pages/api/send-notification.ts
import { NextApiRequest, NextApiResponse } from "next";
import prisma from "@/lib/prisma";
import { sendViewedDocumentEmail } from "@/lib/emails/resend-notification";
export const config = {
maxDuration: 60,
};
export default async function handle(
req: NextApiRequest,
res: NextApiResponse
) {
// We only allow POST requests
if (req.method !== "POST") {
res.status(405).json({ message: "Method Not Allowed" });
return;
}
// POST /api/send-notification
try {
const { viewId } = req.body as {
viewId: string;
};
// Fetch the link to verify the settings
const view = await prisma.view.findUnique({
where: {
id: viewId,
},
select: {
document: {
select: {
owner: {
select: {
email: true,
name: true,
},
},
},
},
},
});
if (!view) {
res.status(404).json({ message: "View / Document not found." });
return;
}
// send email to document owner that document
await sendViewedDocumentEmail({
email: view.document.owner.email as string,
name: view.document.owner.name as string,
});
res.status(200).json({ message: "Successfully sent notification", viewId });
return;
} catch (error) {
console.log("Error:", error);
return res.status(500).json({ message: (error as Error).message });
}
}
```
### #3 Add a Trigger job to make the email sending asynchronous
Our email sending function is ready, but we don't want to send emails synchronously and therefore wait until the email is send before the application responds to the user. We want to offload the email sending to a background job. We'll use Trigger to do that.
In the setup, Trigger CLI created a `jobs` directory in our project. We'll create a new file `notification-job.ts` in that directory and add the following code.
```ts
// jobs/notification-job.ts
import { client } from "@/trigger";
import { eventTrigger, retry } from "@trigger.dev/sdk";
import { z } from "zod";
client.defineJob({
id: "send-notification",
name: "Send Notification",
version: "0.0.1",
trigger: eventTrigger({
name: "link.viewed",
schema: z.object({
viewId: z.string(),
}),
}),
run: async (payload, io, ctx) => {
const { viewId } = payload;
// get file url from document version
const notification = await io.runTask(
"send-notification",
async () => {
const response = await fetch(
`${process.env.NEXT_PUBLIC_BASE_URL}/api/send-notification`,
{
method: "POST",
body: JSON.stringify({ viewId }),
headers: {
"Content-Type": "application/json",
},
}
);
if (!response.ok) {
await io.logger.error("Failed to send notification", { payload });
return;
}
const { message } = (await response.json()) as {
message: string;
};
await io.logger.info("Notification sent", { message, payload });
return { message };
},
{ retry: retry.standardBackoff }
);
return {
success: true,
message: "Successfully sent notification",
};
},
});
```
Add an export to the jobs index file, otherwise Trigger won't know about the job. Small detail but even I have forgotten about this and searched for the error for a good hour.
```ts
// jobs/index.ts
export * from "./notification-job";
```
### Bonus: Prevent rogue access to the API route
We have our API route ready, but we don't want to allow anyone to access it. We want to make sure that only our application can access it. We'll use a simple header authentication key to do that.
In the Trigger job, we'll add the header to the request:
```ts
// jobs/notification-job.ts
..
...
const response = await fetch(
`${process.env.NEXT_PUBLIC_BASE_URL}/api/jobs/send-notification`,
{
method: "POST",
body: JSON.stringify({ viewId }),
headers: {
"Content-Type": "application/json",
Authorization: `Bearer ${process.env.INTERNAL_API_KEY}`, // <- add the authenication header with a local env variable
},
},
);
...
..
```
In the API route, we'll check if the API key matches just before the `try {} catch {}` block:
```ts
// pages/api/send-notification.ts
..
...
// Extract the API Key from the Authorization header
const authHeader = req.headers.authorization;
const token = authHeader?.split(" ")[1]; // Assuming the format is "Bearer [token]"
// Check if the API Key matches
if (token !== process.env.INTERNAL_API_KEY) {
res.status(401).json({ message: "Unauthorized" });
return;
}
...
..
```
Make sure you add the `INTERNAL_API_KEY` to your `.env` file.
```bash
# .env
INTERNAL_API_KEY="YOUR_API_KEY"
```
## Conclusion
Voila! We have our asynchronous email notification system ready. We can now send emails to our users asynchronously without impacting user wait time. We can also use Trigger to offload many other tasks from our main application that we don't want the user to wait for.
Thank you for reading. I am Marc, an open-source advocate. I am building [papermark.io](https://www.papermark.io) - the open-source alternative to DocSend.
Keep on coding!

1,709,292 | React 18 : Exploring the Latest Enhancements and Innovations | Developers may develop dynamic user interfaces using various components with React, a set of... | 0 | 2023-12-27T08:08:24 | https://dev.to/bosctech/react-18-exploring-the-latest-enhancements-and-innovations-o38 |
Developers may develop dynamic user interfaces using various components with React, a set of front-end JavaScript modules. It monitors your changes and makes the appropriate adjustments as needed. React is a massive help for programmers when it comes to debugging. To utilize React, you must install npm and Node.js on your workstation.
Much anticipation has finally been satisfied with the release of React 18, which has jumped ahead of other top UI frameworks in the JavaScript community. React 18’s new out-of-the-box features have drawn many dedicated developers, experts, and passionate contributors since its release.
You can also hire a dedicated Skill React team to get the most of the benefits of this new update. So, here, we’ll closely examine all the brand-new features included in React 18.
**How Is React 18 Different?**
React 18, the latest version of the library is now available. The newest version of React, in contrast to React 17’s traits, has unique features that fix the problems with the older version.
React 18 incorporates several popular functional dependencies to streamline development and boost productivity.
Its unique application programming interfaces (APIs) and HTML file rendering capabilities make it stand out, and its vast collection of professional and author-created materials will assist you in becoming a top-tier developer.
**React 18’s new features**
Some of the new features introduced in React 18 are listed below:
Running multiple react
The most helpful addition to React 18’s feature set is this one, which fixes a significant concurrency problem. Concurrent response is a virtual element that facilitates the simultaneous execution of several user interface instances for developers.
Here, the virtual assistant plays the function of an unseen feature that helps implement the feature by coordinating with backend operations. Because it differs from React’s rendering process, developers must be familiar with Concurrent React.
The Concurrent reply has a reusable state, which is a great feature. It may undo changes made to the user interface and then utilize those changes again differently. There is a forthcoming component called <OffScreen> that may be used with this feature to take the process even further.
Automated batching with improvements
One built-in feature of React is the ability to gather all the state changes using event handlers. In this way, the files are not presented until necessary. Also, React 18 Automatic Batching is an improved version of the Batching technique that simplifies constructing new states by merging them using createRoot.
Apps that do not need background processing, event handlers, batch state changes, timeouts, intervals, and updates are all involved. This code sample shows the significant differences between React 17 and 18. This option may help you save a lot of memory and time.
Enhanced architectural features in the new suspense SSR
Using React Suspense, developers can monitor the rendering components while the process runs. In such instances, a fallback choice will be shown. In the most recent release of React, you may integrate this feature with the transition API.
It restricts your ability to edit the content and even reduces the rendering speed to make loading less noticeable. Until the user experiences a network problem, React Suspense offers a soothing loading state, which is helpful
New start transition API for app responsiveness
The new transition component is part of React 18’s feature set. Depending on how frequently updates happen, developers may choose which ones to prioritize. Pressing, typing, clicking, and other direct engagements make significant impacts. Upon the developer’s request, these changes are promptly put into effect.
Read About A Complete Guide: Hybrid App Development
Transition can be used in two ways
State Transition: If there is no accessible opening hook, the transition stage will be triggered.
User transition: The transition update is initiated via the user transition when a hook is available. The function stores a value to keep track of the pending state.
**What is the best way to update to React 18?**
Simply updating from React 17 to the latest version of the framework will allow you to explore the new features and enhancements introduced by React 18. But if you follow these steps, you can quickly and effectively improve your react js. Just a few seconds are required to follow the straightforward directions.
Follow these steps to install React 18, the latest version, on your development machine.
To install the latest version, use the following command: -npm install react-dom@rc and react@rc.
The yarn add react@rc react-dom@rc operation is required when working with it.
Using the latest version, you may use the additional capabilities and build a robust and aesthetically pleasing application with React JS.
**Enhance Rendering APIs for Clients**
Users downloading React 18 for the first time may see warnings since the ReactDOM.render capability was removed in the most recent version. The program is still using the most current update mode. With the new createRoot capability in React 18, developers no longer need to worry about the render method when rendering their HTML pages.
**Make Server-Side Rendering Improvements**
React components use server rendering to generate HTML files sent to the client. Operating on the principle of a client-server architecture, it mediates communication between the two parties. The earlier streaming APIs have been deprecated as part of React’s 18 new features. Developers are welcome to utilize the newer ones.
**Conclusion**
React 18 represents a significant milestone for the library as it introduces a fundamental change to its operation. Many improvements are automatic optimizations; hence, no code modifications are required.
For those still unsure, upgrading to React 18 is a must.
Because this release is a game-changer rather than merely significant, the React team has spared no effort in making the transition easy for users. You should hire reactjs developers from Bosc Tech Labs to participate in developing future features by the React team.

Throughout that time I have enjoyed learning anything there is to know about SaaS, and how to grow a successful business.
However, with all my projects, one thing has always held back my growth - and that's churn. I would spend hours marketing with cold outreach, SEO, and paid ads but eventually my growth would always get cancelled out by churn and losing customers.
That is why 2 months ago I started working on a platform designed to reduce churn for all SaaS businesses. Here's how it works - after a customer unsubscribes from your platform, our system will automatically send out an email a few days later (which you design), and try to bring the customer back. By throwing in discounts and sharing roadmaps, churned customers are much more likely to re-subscribe with these emails.
After testing out my platform with a cloud storage SaaS business, they saw 1 in 4 churned customers re-subscribe after receiving an email offering a discount and showing off their newly added features. This lead to an increase in revenue of $180 in the testing period, which they wouldn't have seen otherwise.
If you want to play around with it, you can find it at [churnaxe.com](https://churnaxe.com). I would love some opinions, criticism, or any feedback really - and I have created a discount code "AXE" so that the first month is only $5. Thank you all in advance and I hope you give it a shot! | matthowell |

You can annotate a field of type `org.apache.maven.project.MavenProject` with the `@Parameter` annotation and specify `defaultValue = "${project}"` as an annotation attribute to inject the current project as an object into the Mojo.
### Dependency for `MavenProject` inject
Also, you need to add `org.apache.maven:maven-core` as a dependency to have access to `MavenProject`.
I've included more Maven dependencies in my `mvn-show-settings` project (and commented out some injects in the Mojo code) to have a starting point for extending the Mojo by using more information at build time.
### Custom configuration for helper class generation
A custom Maven Mojo project needs some configuration files and a helper class, so it is highly recommeded to include `org.apache.maven.plugins:maven-plugin-plugin` in the build process to auto-generate those files. As a side-note, you might want to configure `helpPackageName` for that plugin to specify the package of the generated helper class. Otherwise, a package name will be generated from the artifact name and will result in a (maybe) unwanted package name.
### Excluding generated code from Checkstyle
I've also added a custom Checkstyle configuration to my project to enforce some coding "standards". By default, all sources will be checked, which also includes the gerenated sources for the helper classes. To prevent those helper classes from being checked, you can specify which directories should be included by the Checkstyle plugin:
```xml
<sourceDirectories>
<sourceDirectory>${project.build.sourceDirectory}</sourceDirectory>
</sourceDirectories>
```
If you configure Checkstyle to be used in the reporting, then you might want to add this configuration there, too.
## What's next?
I'm currently working on some other custom Maven Mojos which I will definitely publish on GitHub, too, and there will also be some interesting details on what you can actually do in custom Maven Mojos.
So, stay tuned. 😉

They liked to share secrets, but there was a sneaky character named Baldev Singh who wanted to steal their secrets.
To keep their messages safe, they called upon the help of a magical guardian named SSH (Secure Shell). SSH gave Raj and Simran each a special key, like a secret code, that only they knew. This key could lock up their messages in a special box that nobody else could open.
Now, when Raj wanted to send a message to Simran, he put it inside the locked box using her secret key. Only Simran, with her matching key, could open the box and read the message. It was like having a secret language that only they understood.
But that's not all! SSH also made sure that Raj and Simran were really themselves and not Baldev Singh pretending to be them. They each had a special ID card, and when they sent messages, they showed their cards to prove it was really them.
With the help of SSH and their secret keys, Raj and Simran could talk and share their secrets without worrying about Baldev Singh or anyone else snooping around. And so, they lived happily and securely in the land of Computers.
The End.

## How Autocoding Platforms Work
Software development can be tedious and time-consuming, with developers writing [boilerplate code](https://aws.amazon.com/what-is/boilerplate-code/) over and over again for common UI elements and interactions. [Autocoding platforms](https://engineering-update.co.uk/2017/08/14/what-is-autocoding-autocodingsys/) aim to solve this problem by automatically generating front-end code from higher-level specifications.
Autocoding platforms allow rapid app development through visual [no-code](https://makerpad.zapier.com/posts/what-is-no-code-a-simple-guide-to-how-no-code-works) or [low-code](https://www.ibm.com/topics/low-code) interfaces that automatically generate code. No-code autocoding enables non-technical users to build full applications by just dragging and dropping UI components and configuring logic visually without writing code. Low-code autocoding provides visual workflows and prebuilt components to accelerate coding while allowing you to view and customize the generated code for your web application.
**No-Code Interface**
* **Visual design canvas** - Drag-and-drop UI components like inputs, buttons, lists, etc., and design responsive layouts visually.
* **Component configuration** - Components and their attributes like styles, content, and behavior can be configured through side panels.
* **Logic and data integration** - Configure application logic and integrations with APIs, databases, etc., through visual workflow builders.
* **Code generation engine** - The core autocoding engine analyses the visual designs and configurations and generates front-end code accordingly.
* **Preview and export** - Preview the generated application and export production-ready code.
### The Promise of Autocoding
Autocoding platforms promise several benefits for streamlining front-end development workflows:
* **[Faster prototyping](9https://www.interaction-design.org/literature/topics/prototyping)** - Visually design and quickly iterate UIs and interactions without coding.
* **Accelerated development** - Eliminate repetitive coding tasks for faster development.
* **Code consistency** - Ensure consistency with autogenerated code that follows defined patterns and conventions.
* **Portability** - Export code to multiple frameworks like React, Vue, Angular, etc.
* **Accessibility** - Many autocoding platforms automatically embed accessibility best practices in generated UIs.
* **Democratized development** - Autocoding opens development capabilities to non-technical users by integrating with low-code/no-code platforms.
## The Power of AI-Assisted Coding
Autocoding platforms utilize advanced AI and machine learning techniques to convert natural language commands into working code, streamlining development workflows. This opens up a world of possibilities for you as a developer using them.
### How Autocoding Uses AI/ML to Generate Code From Commands
Autocoding platforms typically work by using a combination of [natural language processing (NLP)](https://www.techtarget.com/searchenterpriseai/definition/natural-language-processing-NLP) and [deep learning](https://www.techtarget.com/searchenterpriseai/definition/deep-learning-deep-neural-network) to understand your intent and generate the appropriate code. The NLP component parses the developer's command and extracts the key elements, such as the desired functionality, the target programming language, and any required parameters. The deep learning component then uses this information to generate the code, considering factors such as the codebase's style guide and best practices.
* Example of natural language to code conversion
```javascript
// Generated from command: "Create a React component that displays a header with a logo and navigation"
import React from "react";
function Header() {
return (
<header>
<img src="logo.png" alt="Logo" />
<nav>
<ul>
<li>
<a href="/">Home</a>
</li>
<li>
<a href="/about">About</a>
</li>
<li>
<a href="/contact">Contact</a>
</li>
</ul>
</nav>
</header>
);
}
export default Header;
```
* The key steps in the autocode generation process would be:
1. Parse the initial command using NLP to extract key information like `React component`, `header`, `logo`, and `navigation`.
2. Use a deep learning model trained on React code to generate the component boilerplate and `JSX` structure.
3. Insert the relevant UI elements, like the logo and navigation, based on the command.
4. Apply code styling and best practices like naming conventions and formatting.
5. Output the generated code snippet.
The deep learning model is trained on large datasets of existing code to learn common patterns and styles. The natural language command provides a high-level abstraction that the model translates into actual code. Over time, the system can continue to learn and improve from new commands and corrections.

## Streamlining Front-end Workflows
Autocoding platforms have the potential to greatly streamline front-end development workflows for stacks like `React`, `Angular`, and `Vue`. Here are some of the key ways autocoding can accelerate front-end work:
### Faster `CRUD` Application Development
For basic [`CRUD` (create, read, update, delete) applications](https://budibase.com/blog/crud-app/), autocoding can generate full-stack code from natural language commands. For example:
```
Generate a React CRUD application with routing, components, and Firebase integration for a product catalog
```
Could produce starter code for routes, components, state management, and styling to quickly get a `CRUD` app up and running. This can shave hours off typical front-end setup and boilerplate work.
### Rapid UI and Component Generation
Autocoding can generate common UI elements and components simply by describing them. For example:
```
Generate a responsive Vue sidebar component with expand/collapse functionality.
```
Outputs this:
```html
// SidebarItem.vue
<template>
<div>
<div @click="toggle">
{{ title }}
<span v-if="children">
<i v-if="open" class="dropdown icon"></i>
<i v-else class="dropdown right icon"></i>
</span>
</div>
<collapse-transition>
<div v-show="open">
<sidebar-item
v-for="child in children"
:key="child.title"
:title="child.title"
></sidebar-item>
</div>
</collapse-transition>
</div>
</template>
<script>
export default {
props: {
title: {
type: String,
required: true,
},
children: {
type: Array,
default: () => [],
},
},
data() {
return {
open: false,
};
},
methods: {
toggle() {
this.open = !this.open;
},
},
};
</script>
// Sidebar.vue
<template>
<div class="sidebar">
<sidebar-item
v-for="item in menu"
:key="item.title"
:title="item.title"
:children="item.children"
></sidebar-item>
</div>
</template>
<script>
import SidebarItem from "./SidebarItem.vue";
export default {
components: {
SidebarItem,
},
data() {
return {
menu: [
{
title: "Dashboard",
children: [{ title: "Overview" }, { title: "Stats" }],
},
{
title: "Content",
children: [{ title: "Pages" }, { title: "Posts" }],
},
],
};
},
};
</script>
<style>
/* styles */
body {
font-family: Arial, sans-serif;
}
.sidebar {
background-color: #333;
color: #fff;
padding: 20px;
}
.sidebar-item {
cursor: pointer;
margin-bottom: 10px;
}
.dropdown {
margin-left: 10px;
}
.nested {
margin-left: 20px;
}
</style>
```
This improves productivity by enabling you to get the scaffolding for UI features and components without all the manual coding.
### Faster Prototyping and Iteration
With the ability to go from idea to code instantly in many cases, autocoding can accelerate prototyping and build/test iterations. As a developer, you can validate ideas and get user feedback faster before investing heavily in hand-coding a final product.
The key benefits are:
Quicker concept validation.
Faster iteration on UX and styling choices.
Overall improved collaboration between teams.
This lets you spend more time on complex logic and customization than repetitive boilerplate work.
While autocoding platforms have limitations, they offer exciting potential to streamline many common front-end workflows. Integrating natural language code generation into your tools could significantly boost productivity for your team.
## Autocoding in Action
Let's look at some leading examples and see autocoding in action.

Integrating Content Delivery Networks (CDNs) into your web development toolbox is nothing short of a revelation. These networks are powerhouses, enhancing website performance and delivering substantial energy-efficient benefits. CDNs revolutionize content delivery by distributing it across a network of strategically located servers worldwide. When a user requests a page, the CDN serves up content from the server closest to them, reducing the distance data must travel and, in turn, curbing energy consumption. Traditional web hosting, in contrast, often involves data traversing vast distances, loading down servers, and escalating energy usage. CDNs minimize these inefficiencies, championing a more sustainable approach to content delivery.
But that's not all – CDNs also wield the magic wand of faster load times. This not only elevates user experience but also translates into reduced energy consumption and more efficient web server operation. Furthermore, they enhance website reliability by distributing traffic across multiple servers, ensuring your website remains accessible even if one server experiences issues. This redundancy reduces the need for excess server capacity, creating a more sustainable server management ecosystem and less energy waste. This pioneering technology further contributes to a greener web, reducing your website's carbon footprint while delivering a superior user experience.
### Sustainable CDN providers
There are several sustainable CDN providers available, including:
* [Cloudflare](https://www.cloudflare.com/)
* [Akamai](https://www.akamai.com/)
* [EdgeCast](https://edg.io/)

Adding particle animation to web projects can enhance the overall user experience and make your website or web application more engaging and visually appealing. Here are some of the key benefits of incorporating particle animation into your web projects:
- Visual Appeal: Particle animations can make your website more visually appealing by adding dynamic and eye-catching elements. They can create a sense of depth and interactivity, making your site stand out from the competition.
- User Engagement: Animations are attention-grabbing, and they can help keep users engaged with your content. Interactive particles can encourage users to interact with your site and explore its features.
- User Interaction: Interactive particle animations can respond to user actions, such as mouse movements or touches, making the website more responsive and interactive. This can improve the overall user experience.
- Background Effects: Particle animations are often used for background effects, providing an attractive backdrop for your content. This can be effective for landing pages, portfolios, and other visually oriented websites.
## Installation and setup of React TsParticles
In your React application project directory, you can install the [TsParticles](https://particles.js.org/) dependency with your preferred package installer using the following bash scripts:
For `npm`:
```
npm install react-tsparticles tsparticles
```
For `yarn`:
```
yarn add react-tsparticles tsparticles
```
## Creating animations with TsParticles
In this section, we will discuss the different animations TsParticles provides and how they can be integrated into web applications.
### Confetti Effects
For our first animation, we will use TsParticles to generate confetti on a web application. Confetti are small multi-colored pieces of material usually thrown on special celebration occasions. In a web application, it can be used to depict a form of celebration in instances where users complete an object, e.g., completing a course on an e-learning website.
To create this animation, follow the steps outlined below:
* First, in the `src/App.js` directory, we will clear the boiler template code and import the necessary `TsParticle` dependencies:
```javascript
import Particles from "react-tsparticles";
import { loadFull } from "tsparticles";
import { useCallback } from "react";
```
* Next, we will define the animation configuration and a function to initialize the TsParticles animation:
```javascript
//...
function App() {
const config = {
//Here we define the animation type, properties and behavior
};
const particlesInit = useCallback(async (engine) => {
// here we initialize the particles animation
await loadFull(engine);
}, []);
```
We will use `useCallback` to memorize the `particleInit` function, hence as the dependency array is empty `[]`, React will not create a new function on each render, but will only create such on the first render when the component mounts.
In the `return` block of the `App.js` component, we can access the animation with the `config` and initialization function:
```javascript
//...
return (
<div className="App">
<Particles options={config} init={particlesInit} />
</div>
);
export default App;
```
For the confetti animation, we will define the following properties in the `config`:
```javascript
const config = {
fullScreen: {
zIndex: 1,
},
background: {
color: "#000",
},
emitters: {
position: {
x: 50,
y: 100,
},
rate: {
quantity: 5,
delay: 0.15,
},
},
particles: {
color: {
value: ["#1E00FF", "#FF0061", "#E1FF00", "#00FF9E"],
},
move: {
decay: 0.05,
direction: "top",
enable: true,
gravity: {
enable: true,
},
outModes: {
top: "none",
default: "destroy",
},
speed: {
min: 50,
max: 100,
},
},
number: {
value: 0,
},
opacity: {
value: 1,
},
rotate: {
value: {
min: 0,
max: 360,
},
direction: "random",
animation: {
enable: true,
speed: 30,
},
},
tilt: {
direction: "random",
enable: true,
value: {
min: 0,
max: 360,
},
animation: {
enable: true,
speed: 30,
},
},
size: {
value: 10,
animation: {
enable: true,
startValue: "min",
count: 1,
speed: 16,
sync: true,
},
},
shape: {
type: ["circle", "square"],
options: {},
},
},
};
```
We can define the function of each attribute specified above:
- Fullscreen: In this property, we set the stacking order of the intended animation to “1” using the `z-index` attribute.
- Emitters: Here, we specified the initial X and Y origin points of the particle animation using the `position` attribute. Using `rate`, we also specified the quantity emitted at a time and the delay between each creation of particles.
- Particles: Using this property, we defined the emitted particles' qualities and behavior.
- Color: This can be a single color or a collection of different colors, as shown above. This sets the color for each particle created in the animation.
- Move: This property defines:
- The `direction` of the particle animation.
- At what point the particles begin to lose speed is specified using the `decay` attribute.
- We also enabled the effect of gravity on the particles by setting the `gravity` attribute to true.
- Number: This is the initial number of particles for the animation.
`opacity`, `rotate`, `tilt`, `size`, and `shape` all perform the functions implied by their names. To run the application, use the `npm start` command in the terminal environment of the working directory and open the result in the browser. You will get a page similar to the GIF below:
By modifying the `config` properties, we can create unique forms of animation in TsParticles. For example, we can get a confetti pop animation with the following code:
```javascript
const config = {
fullScreen: {
zIndex: 1,
},
background: {
color: "#000",
},
emitters: {
life: {
count: 0,
duration: 0.1,
delay: 0.4,
},
rate: {
delay: 0.1,
quantity: 150,
},
size: {
width: 0,
height: 0,
},
},
particles: {
color: {
value: ["#1E00FF", "#FF0061", "#E1FF00", "#00FF9E"],
},
move: {
enable: true,
gravity: {
enable: true,
acceleration: 10,
},
speed: {
min: 10,
max: 20,
},
decay: 0.1,
direction: "none",
straight: false,
outModes: {
default: "destroy",
top: "none",
},
},
number: {
value: 0,
},
opacity: {
value: 1,
animation: {
enable: true,
minimumValue: 0,
speed: 2,
startValue: "max",
destroy: "min",
},
},
rotate: {
value: {
min: 0,
max: 360,
},
direction: "random",
animation: {
enable: true,
speed: 30,
},
},
tilt: {
direction: "random",
enable: true,
value: {
min: 0,
max: 360,
},
animation: {
enable: true,
speed: 30,
},
},
size: {
value: 10,
random: {
enable: true,
minimumValue: 2,
},
},
shape: {
type: ["circle", "square"],
options: {},
},
},
};
```
Running the application will produce the following results:
### Fireworks Effects
In this section, we will create a fireworks effect with TsParticles using the following steps:
- First, we will set a black background and a Fullscreen property for the fireworks to be well visible. We will also define a `fpsLimit` for a better none choppy animation and a `detectRetina` value of “true” to improve the particle appearance:
```javascript
const config = {
fullScreen: {
enable: true,
},
detectRetina: true,
background: {
color: "#000",
},
fpsLimit: 60,
};
```
- Next, we will define the emitter property of our particles. To imitate actual fireworks, we will need the particles to be animated upwards, to different x and y coordinates before we can create the explosion effect:
```javascript
//...
emitters: {
direction: "top",
position: {
y: 100,
x: 50,
},
rate: {
delay: 0.03,
quantity: 1,
},
life: {
count: 0,
duration: 0.1,
delay: 0.1,
},
size: {
width: 80,
height: 0,
},
//...
```
We also defined the particles' `rate`, `life`, and `size` properties. Next, we will create and animate the `particles `to be animated:
```javascript
// still within the emitters property
particles: {
number: {
value: 0,
},
destroy: {
mode: "split", // using splits we will achieve a firework effect
split: {
rate: {
value: 100, //number of splits to be created
},
particles: {
// Splitted practicle properties
color: {
//color of particles after explosion
value: [
"#FF0000" /*Red */,
"#0000FF" /*blue */,
"#FFFF00" /*yellow*/,
],
},
opacity: {
value: 1,
animation: {
enable: true,
speed: 0.2,
minimumValue: 0.1,
sync: false,
startValue: "max", // create multiple fireworks
destroy: "min",
},
},
shape: {
// pattern of the explosion
type: "star",
},
size: {
value: 3,
animation: {
enable: false,
},
},
life: {
count: 1, //amount of time
duration: {
value: {
min: 1,
max: 2,
},
},
},
move: {
enable: true,
gravity: {
enable: false,
},
speed: 3,
direction: "none",
outMode: "destroy",
},
},
},
},
life: {
count: 1,
},
shape: {
type: "line",
},
size: {
value: { min: 1, max: 100 },
animation: {
enable: true,
sync: true,
speed: 150,
startValue: "random",
destroy: "min",
},
},
stroke: {
color: {
// color of the fireworks stroke
value: ["#00FFFF", "#FF8000", "#0080FF"],
},
width: 1,
},
rotate: {
path: true,
},
move: {
enable: true,
gravity: {
acceleration: 15,
enable: true,
inverse: true,
maxSpeed: 100,
},
speed: { min: 10, max: 20 },
outModes: {
default: "destroy",
},
trail: {
// trail for split particles
enable: true,
length: 10,
},
},
},
```
Running the application will produce the following results:
### Using Presets
While creating the particle configuration offers more flexibility in controlling the animation properties, it can take some time to get things right. To quickly provide particle animations, TsParticles introduced the use of preset particles. The preset allows users to import and use pre-configured particle animation.
For example, we can use the fireworks preset provided by TsParticles, as shown below.
First, we install the preset using the following command in the CLI:
```
npm install tsparticles-preset-fireworks
```
We can then import and use it as shown below:
```javascript
import Particles from "react-tsparticles";
import { loadFull } from "tsparticles";
import { useCallback } from "react";
import { loadFireworksPreset } from "tsparticles-preset-fireworks";
const fireworkInit = useCallback(async (engine) => {
await loadFireworksPreset(engine);
}, []);
const options = {
preset: "fireworks",
};
return (
<div className="App">
<Particles options={options} init={fireworkInit} />
</div>
);
}
```
Final results:
## Implementing interactivity with particles
In this section, we will learn how to generate TsParticle animations based on user interactions, such as click and hover events. A mouse click event can trigger the particle `emitter` action, as shown in the code below:
```javascript
background: {
color: "#000",
},
interactivity: {
events: {
onClick: {
enable: true,
mode: "emitter",
},
},
// emitter and mode here
},
```
Next, we define a `mode` that houses the `emitter` property, and then we add the rest of the animation properties:
```javascript
//....
modes: {
emitters: {
direction: "top",
spawnColor: {
value: "#FF8000",
animation: {
h: {
enable: true,
offset: {
min: -1.4,
max: 1.4,
},
speed: 0.1,
sync: false,
},
l: {
enable: true,
offset: {
min: 20,
max: 80,
},
speed: 0,
sync: false,
},
},
},
life: {
count: 1,
duration: 0.1,
delay: 0.6,
},
rate: {
delay: 0.1,
quantity: 100,
},
size: {
width: 0,
height: 0,
},
},
},
```
Finally, we define the particles' properties:
```javascript
particles: {
number: {
value: 0,
},
color: {
value: "#0080FF",
},
shape: {
type: ["circle", "square", "triangle"],
},
opacity: {
value: { min: 0, max: 1 },
animation: {
enable: true,
speed: 1,
startValue: "max",
destroy: "min",
},
},
size: {
value: { min: 6, max: 12 },
},
life: {
duration: {
sync: true,
value: 7,
},
count: 1,
},
move: {
enable: true,
gravity: {
enable: true,
},
drift: {
min: -2,
max: 2,
},
speed: { min: 10, max: 30 },
decay: 0.1,
direction: "none",
random: false,
straight: false,
outModes: {
default: "destroy",
top: "none",
},
},
rotate: {
value: {
min: 0,
max: 360,
},
direction: "random",
move: true,
animation: {
enable: true,
speed: 60,
},
},
tilt: {
direction: "random",
enable: true,
move: true,
value: {
min: 0,
max: 360,
},
animation: {
enable: true,
speed: 60,
},
},
roll: {
darken: {
enable: true,
value: 25,
},
enable: true,
speed: {
min: 15,
max: 25,
},
},
wobble: {
distance: 30,
enable: true,
move: true,
speed: {
min: -15,
max: 15,
},
},
},
```
In the code above, we are creating a confetti pop effect animated upwards, with its point of origin at the location where a mouse click takes place:
In a similar pattern, we can also define hover animations, which emit particles as the mouse hovers on the screen. For this, we will also use the `interactivity` property:
```javascript
const config = {
background: {
color: "#000",
},
interactivity: {
detectsOn: "window",
events: {
onhover: {
enable: true,
mode: "trail"
},
//...
```
Here, we define the area (i.e., window) to detect mouse events and the type of events to be detected. We will create a mouse trail using an `onhover` effect:
```javascript
//...
resize: true,
},
modes: {
grab: {
distance: 400,
line_linked: {
opacity: 1,
},
},
bubble: {
distance: 400,
size: 40,
duration: 2,
opacity: 0.8,
speed: 3,
},
repulse: {
distance: 200,
},
push: {
particles_nb: 4,
},
remove: {
particles_nb: 2,
},
trail: {
delay: 0.005,
quantity: 5,
pauseOnStop: true,
},
},
},
retina_detect: true,
fullScreen: {
enable: true,
zIndex: 100,
},
fpsLimit: 60,
particles: {
number: {
value: 0,
density: {
enable: true,
value_area: 800,
},
},
color: {
value: "#0080FF",
},
shape: {
type: ["circle", "square", "triangle"],
},
opacity: {
value: { min: 0, max: 1 },
animation: {
enable: true,
speed: 1,
startValue: "max",
destroy: "min",
},
},
size: {
value: { min: 6, max: 12 },
},
links: {
enable: false,
},
move: {
enable: true,
speed: 3.5,
direction: "none",
random: false,
straight: false,
outMode: "destroy",
attract: {
enable: false,
rotateX: 600,
rotateY: 1200,
},
},
},
//...
```
Running the application will produce the following results:
<CTA_Middle_Programming />
## Handling responsiveness
With TsParticles, we can also define the behavior of particles under different screen sizes, as shown below:
```javascript
responsive: [
{
maxWidth: 1024,
options: {
particles: {
move: {
speed: {
min: 33,
max: 66,
},
},
},
},
},
],
```
In the code block above, we defined a move speed of 33 and 66 for minimum and maximum values at a screen with `maxWidth` 1024px. Therefore, all screens less than 1024px in size will have properties within the defined breakpoint applied to their particles.
## Integration with other React components
In this section, we will learn how to toggle particle animations from actions performed by other components. Actions, such as buttons or completing a progress bar, can trigger these animations.
### Button
Using animations, we can bring life to simple user interactions, such as clicking on a subscriber button or finishing a form sign up.
To trigger particle animations from a button, follow the steps outlined below:
- First, we will create a new file, `Button.jsx` to contain a component for the button, add our necessary imports, and create a button:
```javascript
import React, { useState } from "react";
import Particles from "react-tsparticles";
import { loadFull } from "tsparticles";
import { useCallback } from "react";
const Button = () => {
const [subscribed, setSubscribed] = useState(false);
// confetti particles animation here
return (
<div
style={{
display: "flex",
height: "100vh",
width: "100vw",
flexDirection: "column",
justifyContent: "center",
alignItems: "center",
gap: "23px",
background: "black"
}}
>
<button
id="#myButton"
style={{
padding: "10px 23px",
fontWeight: 700,
width: "max-content",
border: "1px solid black",
borderRadius: "12px",
background: subscribed ? "red" : "white",
color: subscribed ? "white" : "black",
transform: "scale(2)",
}}
onClick={() => setSubscribed(!subscribed)}
>
{subscribed ? "Unsubscribe" : "Subscribe"}
</button>
<p style={{ fontSize: "40px", color: "white" }}>
{/* subscription caption */}
{!subscribed
? "Subscribe to my news letter to get regular updates"
: "Thank you for subscribing. Cheers!!!"}
</p>
// return particles component when subscribed is true
</div>
);
};
export default Button;
```
After this, we can create the `TsParticles` config and set the `Particles` component to be displayed when the `subscribe` state is true:
```javascript
// pop confetti
const config = {
fullScreen: {
zIndex: 1,
},
emitters: {
position: {
x: 50,
y: 100,
},
rate: {
quantity: 25,
delay: 0.15,
},
spawnColor: {
value: "#FF8000",
animation: {
h: {
enable: true,
offset: {
min: -1.4,
max: 1.4,
},
speed: 0.1,
sync: false,
},
l: {
enable: true,
offset: {
min: 20,
max: 80,
},
speed: 0,
sync: false,
},
},
},
life: {
count: 1,
duration: 7,
delay: 0.6,
},
size: {
width: 0,
height: 0,
},
},
particles: {
color: {
value: ["#1E00FF", "#FF0061", "#E1FF00", "#00FF9E"],
},
move: {
decay: 0.05,
direction: "top",
enable: true,
gravity: {
enable: true,
},
outModes: {
top: "none",
default: "destroy",
},
speed: {
min: 50,
max: 100,
},
},
number: {
value: 0,
},
opacity: {
value: 1,
},
rotate: {
value: {
min: 0,
max: 360,
},
direction: "random",
animation: {
enable: true,
speed: 30,
},
},
tilt: {
direction: "random",
enable: true,
value: {
min: 0,
max: 360,
},
animation: {
enable: true,
speed: 30,
},
},
size: {
value: 8,
animation: {
enable: true,
startValue: "min",
count: 1,
speed: 16,
sync: true,
},
},
roll: {
darken: {
enable: true,
value: 25,
},
enlighten: {
enable: true,
value: 25,
},
enable: true,
speed: {
min: 5,
max: 15,
},
},
wobble: {
distance: 30,
enable: true,
speed: {
min: -7,
max: 7,
},
},
shape: {
type: ["circle", "square"],
options: {},
},
},
};
const particlesInit = useCallback(async (engine) => {
await loadFull(engine);
}, []);
```
In the code block above, we created a state `subscribed` to manage the text to be shown and also the CSS properties of the button. At the end of the `return` block, add:
```javascript
{subscribed ? <Particles options={config} init={particlesInit} /> : null}
```
With this, we toggle the `subscribed` value when the button is clicked. It shows the particles:
### Progress bar Indicator
Progress bar indicators are a sign of advancement users have put into a task. This could be the completion of a course or even scrolling to the bottom of the page. Using animations, we can trigger a relaxing effect on users by offering them a sign of accomplishment. Similar to the button example in the previous section, we can trigger a particle animation when a slider reaches a value of “100%”:
```javascript
import React, { useState, useEffect } from "react";
const Slider = () => {
const [scrolled, setScrolled] = useState(0);
useEffect(() => {
window.onscroll = function () {
var winScroll =
document.body.scrollTop || document.documentElement.scrollTop;
var height =
document.documentElement.scrollHeight -
document.documentElement.clientHeight;
setScrolled((winScroll / height) * 100);
};
}, []);
return (
<div
style={{
display: "flex",
minHeight: "100vh",
flexDirection: "column",
alignItems: "center",
position: "relative",
padding: "0 120px",
background: "#333"
}}
>
<progress
value={scrolled}
max={100}
style={{
width: "80%",
height: "30px",
marginTop: "15px",
position: "fixed",
top: "0",
}}
></progress>
<h1
style={{
marginTop: "80px",
color:"white",
}}
>
{/* content */}
{/* Page content. For this example, I am using random AI generated text */}
</h1>
</div>
);
};
export default Slider;
```
In the code block above, we created a progress indicator that shows how much of the page the user has scrolled. We will trigger the particles animation when users scroll to the bottom of the page:
```javascript
// dependencies
import Particles from "react-tsparticles";
import { loadFull } from "tsparticles";
import { useCallback } from "react";
// config and particles init function
const config = {
fullScreen: {
enable: true,
},
detectRetina: true,

},
},
},
move: {
//all about firework showers
enable: true, // to get the fireworks effect
gravity: {
enable: false, //stops gravity from pulling them up
},
speed: 3, //speed of the fireworks
direction: "none", //direction of the fireworks
outMode: "destroy", // avoids overlapping of fireworks
},
},
},
},
life: {
count: 1,
},
shape: {
type: "line",
},
size: {
value: { min: 1, max: 100 },
animation: {
enable: true,

}, []);
```
In the code block above, we imported the `TsParticles` dependency and created a config for the fireworks animation we carried out earlier. To show the animation when the progress is full, we need to set a condition that checks if the value of `scrolled` is 100, and renders the `Particles` component:
```javascript
{scrolled === 100 ? (
<Particles options={config} init={particlesInit} />
) : null}
```
Final results:
## Conclusion
During this article, we discussed the React TsParticles library and its visual benefits when incorporated into web applications. We also showed the steps to set up and implement TsParticles in a React application. Furthermore, we also discussed customizing particle animation behaviors using user interactions and integration with other React components.

1,710,593 | A Beginner's Tutorial on Modifying the Index HTML in Nginx | In this guide, we’ll delve into the process of changing the index HTML file in Nginx. The index HTML... | 0 | 2023-12-28T12:24:27 | https://dev.to/fpesre/a-beginners-tutorial-on-modifying-the-index-html-in-nginx-2ef5 | devops, web, kubernetes, beginners | In this guide, we’ll delve into the process of changing the index HTML file in Nginx. The index HTML file is the default file served when a user visits a website. By altering this file, you can customize your website’s content and appearance. As we walk through the steps to modify the Nginx index HTML in Kubernetes with configmap, we’ll first gain an understanding of the Nginx configuration file and its location. Then, we’ll learn how to locate and modify the index HTML file. Let’s dive in!
**Understanding the Nginx Configuration File.**
The Nginx configuration file is where you can specify various settings and directives for your server. This file is crucial for the operation of your Nginx server. It’s typically located at **/etc/nginx/nginx.conf**, but the location can vary depending on your specific Nginx setup.
**Locating the Index HTML File**
The index HTML file is the default file that Nginx serves when a user accesses a website. It’s usually located in the root directory of the website. To find the location of the index HTML file, check the Nginx configuration file for the root directive. This directive specifies the root directory of the website. Once you’ve located the root directory, the index HTML file is typically named **index.html** or **index.htm**. It’s important to note that the location of the index HTML file may vary depending on the specific Nginx configuration.
```
server {
listen 80;
server_name example.com;
root /var/www/html;
location / {
try_files $uri $uri/ =404;
}
}
```
If the root directive is not immediately visible within the main nginx.conf file, it’s often because it resides in a separate configuration file. These files are typically found in the conf.d or sites-enabled directories. Such a structure allows for cleaner and more organized management of different websites or domains hosted on a single server. By separating them, Nginx can apply specific settings to each site, including the location of its index HTML file.
```
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
# multi_accept on;
}
http {
# Basic Settings
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# SSL Settings
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
# Logging Settings
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
# Gzip Settings
gzip on;
gzip_disable "msie6";
# Virtual Host Configs
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
```
**Editing the Nginx Configuration File**
To edit the Nginx configuration file, follow these steps:
1. Open the terminal or command prompt.
2. Navigate to the directory where the Nginx configuration file is located.
3. Use a text editor to open the configuration file (e.g., sudo nano nginx.conf).
4. Make the necessary changes to the file, such as modifying the server block or adding new location blocks.
5. Save the changes and exit the text editor.
6. Test the configuration file for syntax errors by running sudo nginx -t.
7. If there are no errors, reload the Nginx service to apply the changes (e.g., sudo systemctl reload nginx).
Remember to back up the configuration file before making any changes, and double-check the syntax to avoid any errors. If you encounter any issues, refer to the Nginx documentation or seek assistance from the Nginx community.
**Modifying the Index HTML File**
To modify the index HTML file in Nginx, follow these steps:
1. Locate the index HTML file in your Nginx configuration directory.
2. Open the index HTML file in a text editor.
3. Make the necessary changes to the HTML code.
4. Save the file and exit the text editor
**Common Questions:**
- Where can I find the configuration file for Nginx?
* Look for the Nginx configuration file at **/etc/nginx/nginx.conf**.
- Is it possible to relocate the index HTML file within Nginx?
* Indeed, by altering the Nginx configuration file, you can shift the index HTML file’s location.
- What steps should I follow to modify the Nginx configuration file?
* Utilize a text editor like nano or vim to make edits to the Nginx configuration file.
- Where does Nginx usually store the index HTML file by default?
* Nginx generally keeps the index HTML file in the **/usr/share/nginx/html** directory.
- Am I able to edit the index HTML file directly?
* Absolutely, you have the ability to update the index HTML file with a text editor.
- Should I restart Nginx to apply new configurations?
* Restarting Nginx is required to activate any new configuration changes.
**The Practicality of Mastery in Nginx Configuration**
Understanding the **nginx.conf** file isn’t just academic—it’s a vital skill for real-world applications. Whether you’re deploying a simple blog or a complex microservices architecture with Kubernetes, the need to tweak **nginx.conf** surfaces frequently. For instance, when securing communications with SSL/TLS, you’ll dive into this file to point Nginx to your certificates. Or perhaps you’re optimizing performance; here too, **nginx.conf** holds the keys to tweaking file caching and client connection limits.
It’s in scenarios like setting up a reverse proxy or handling multiple domains where mastering **nginx.conf** moves from being useful to being essential. By mastering the location and editing of the index HTML file, you empower yourself to respond dynamically to the needs of your site and your audience. So, take the helm, customize confidently, and remember that each change is a step towards a more tailored and efficient web experience.

As a bride or groom, your wedding day will be one of the most memorable events of your life. However, with so much going on during your wedding, it can be easy to feel overwhelmed and miss out on capturing some important moments. Luckily, leveraging today's technology allows you to connect your online and offline worlds, enhance your guests' experience, and ensure you have memories from your special day that will last forever. Incorporating dynamic QR codes, social media, live streaming, and photo sharing apps into your wedding planning helps to bridge the gap between your digital and physical realms. Read on to discover how implementing tech at your wedding lets you check in, share updates, and capture each meaningful moment.
**## Streamline the Registration Process With QR Codes
**
To create a seamless guest experience at your wedding, incorporate technology to streamline key processes. One way to do this is by using quick response (QR) codes for a touch-free registration and check-in.
QR codes are two-dimensional barcodes that can be scanned using the camera on a smartphone. By [generating a QR code](https://www.uniqode.com/qr-code-gen
erator) for your wedding and sharing it with guests in advance, you can direct them to a digital registration form to collect important information like:
- Names and contact details
- Meal selections
- Song requests
- Transportation needs
This allows guests to register at their convenience prior to the wedding day and avoids congestion and long lines onsite. You can create an online registration form using services like Google Forms, Uniqode, SurveyMonkey or JotForm and then generate a QR code to link to it.
QR codes are customizable, so you can modify the colors and add your wedding logo to complement your theme and stationery. Place the code on your wedding website, save-the-date cards, and signage at the venue entrance so guests can scan and check in quickly. Using technology in this simple yet effective way will make your guests feel well cared for from the first point of contact and allow you to focus on enjoying this special day. With streamlined registration and check-in, you’ll have more time to spend with loved ones who have gathered to honor your cherished new beginning.
## **Share the Special Moments on Social Media
**
To successfully incorporate technology into your wedding, consider leveraging social media to share special moments with guests unable to attend as well as those celebrating from afar.
Social media platforms like Facebook, Instagram, and WhatsApp allow you to broadcast highlights of your big day in real-time. Share photos of the ceremony, your first dance, cake cutting, and more. These posts create excitement and allow guests following along to feel involved, even from a distance.
For example, you might post:
- A photo of you walking down the aisle captioned, “Here comes the bride!”
- A Boomerang or short video of your first dance with the message, “First dance complete!”
- A photo of you and your new spouse cutting the cake with the caption, “Mr. and Mrs.!”
To avoid distraction, designate a family member or friend to handle posting to your accounts so you can remain present and enjoy each moment. Let guests know they are welcome to post their own photos and videos using your wedding hashtag. This curated stream of social shares becomes a crowdsourced story of your wedding day.
By utilizing social media and technology in a meaningful way, you can craft an interactive experience for on-site and remote guests alike. Though sharing on social media has its drawbacks, when used intentionally it can be a powerful way to spread joy on your wedding day. Overall, focus on living in each moment with your loved ones, using technology only to enhance and share the experience.
## **Capture Guest Memories With a Photo Booth
**
A wedding photo booth allows guests to capture memorable moments in a casual, fun way. Setting up a photo booth at your wedding is an opportunity for guests to take photos with friends and family to cherish for years to come.
**Provide Props and Accessories
**
Supply a variety of props and accessories like silly hats, glasses, signs, and other theme-related items. This allows guests to be creative and customize their photos. Having props on hand also makes the photo booth experience more engaging and interactive. Consider including props that represent the wedding theme or location. For example, at a beach wedding provide leis, sunglasses and flip flops.
**Share Digital Copies
**
Offer guests the ability to share digital copies of their photo booth pictures. Many modern photo booth services provide options for social media sharing directly from the booth. Guests can post their photos to platforms like Facebook, Instagram, and Twitter during the event. Sharing on social media also allows guests not in attendance to feel included in the festivities from afar.
**Use a Dynamic QR Code
**
Incorporate a dynamic QR code that links directly to an online gallery of all the photo booth pictures. Guests can scan the QR code with their smartphone camera to instantly view, download and share every photo from the booth. A dynamic QR code also makes it simple for the bride and groom to share the full gallery with all guests after the wedding.
**Capture a Timelapse Video
**
Some photo booths offer the ability to capture a timelapse video of all the photos taken during the event. The final timelapse shows guests coming in and out of the booth, taking photos and having fun. This creates a short video that captures the energy and excitement of the photo booth experience. The timelapse can then be shared with all guests as a memento of the wedding.
Providing a photo booth, props, the ability to share photos digitally and a timelapse video gives wedding guests an opportunity to capture and share memories in an engaging way. These interactive and memorable experiences help to bridge the gap between the online and offline aspects of your wedding.
## **Create a Custom Wedding Hashtag to Curate Guest Photos
**
To capture memories from your wedding day that will last a lifetime, creating a custom wedding hashtag is a must. A wedding hashtag allows guests to tag photos they take at your wedding on social media, compiling them in one place for you and others to enjoy for years to come.
**Choose a Personalized Hashtag
**
Select a hashtag that incorporates your names, wedding date or a meaningful word or phrase. For example, #TomAndSallyWeddingBliss or #HappilyEverAfter060119. There are free hashtag generators online to help create options if you need inspiration. Be sure to share your hashtag on your wedding website, invitations, programs, and signage at the reception to spread the word.
**Monitor and Curate the Hashtag
**
Check your hashtag regularly leading up to and on your wedding day. Like and comment on photos from guests to show your appreciation for them sharing the moment. You may also want to curate the stream of images by hiding any inappropriate photos. Some couples create a separate social media account just for their wedding photos to make curating and sharing easier.
**Create a Wedding Photo Gallery
**
After the wedding, compile your favorite shots from the hashtag into a photo gallery on your website or a wedding photo sharing app. This makes it easy for guests to relive and share memories from your celebration. Some apps like WedPics, Wedding Party and Wedding Spot allow you to collect photos from your wedding hashtag and instantly create custom galleries.
**Incorporate a QR Code for Easy Registration
**
To simplify the registration process, provide guests with a QR code that links to your guestbook or a digital form to collect contact information. Have the code printed on signage, programs or escort cards to scan with their smartphone camera. This eliminates confusion over hard to read handwriting and ensures you receive the correct details from each guest.
Leveraging technology and social media at your wedding is a meaningful way to bridge the gap between your online and offline worlds. Creating a custom hashtag, curating the content, and incorporating QR codes are all inclusive and efficient ways for guests to check in, share the moment and capture memories that will last long after the last dance.
## **Provide Wi-Fi for Guests to Post Easily
**
To enhance your guests’ experience at your wedding, providing Wi-Fi access is highly recommended. With Wi-Fi, your guests can easily post updates, photos and share the moments from your special day on social media in real-time.
**Set Up the Network
**Work with your wedding venue coordinator to arrange Wi-Fi access for your guests. Provide the network name and password on a sign at the entrance or include the information on the wedding program. For the network name, consider something like “BrideAndGroomWeddingWiFi” and a simple, easy-to-remember password.
**Share the Hashtag
**Create a unique hashtag for your wedding and share it on your wedding website, invitations and at the venue. For example, “#TomAndJennyTieTheKnot”. Your guests can then tag their social media posts with the hashtag allowing everyone to see photos and updates in one place.
**Provide Charging Stations
**Set up charging stations around the venue so your guests’ devices do not lose power during the event. Consider offering portable phone chargers that can be borrowed as well. With charged devices and Wi-Fi, your guests can post and share all night long.
**Share a Live Photo Album
**Set up a live photo album or slideshow where guests can upload photos directly to be displayed on monitors around the venue. Services like WedPics, The Guest and Veri provide easy ways for your guests to share photos to a live feed. Not only will guests enjoy seeing their photos on display but it creates an interactive experience for all.
**Include a QR Code for Guest Book Sign-In
**Rather than a traditional paper guest book, include a unique QR code on signage for your guests to scan upon arrival. The QR code can link to a digital guest book where guests sign in and leave well wishes. Services like QR Code Generator and The Guest offer digital guest book features with custom QR codes for weddings. A digital guest book allows for an innovative sign-in process and a keepsake you can enjoy for years to come.
With some thoughtful planning, you can effectively bridge the gap between the online and offline world at your wedding. Leveraging technology and providing digital features will lead to an enhanced experience for both you and your guests. Memories can be captured, shared and relived instantly.
## **Conclusion
**
As you plan your wedding, don't forget that technology can be an ally and help enhance your guests' experience. By incorporating tech elements that encourage people to check-in, share memories, and capture moments, you create an event that bridges the gap between the online and offline world. A dynamic QR code for easy registration, a social media photo booth, a wedding website and app for schedules and information, live streaming for those who couldn't attend - these are all simple ways to leverage technology and craft an unforgettable celebration. Your wedding is a chance to bring people together and create new memories. With some smart uses of tech, you can achieve all that and more.

1,711,429 | Web scraping para extraer información utilizando requests y BeautifulSoup en Python | Introducción En el mundo de la programación, el scraping web se ha convertido en una... | 0 | 2023-12-29T08:20:02 | https://dev.to/albertgilopez/web-scraping-para-extraer-informacion-utilizando-requests-y-beautifulsoup-en-python-mmm | python, webscraping, requests, beautifulsoup | ## Introducción
En el mundo de la programación, el scraping web se ha convertido en una técnica esencial para extraer información útil de sitios web. En esta guía, voy a explorar contigo cómo implementar scraping web utilizando Python, específicamente con las bibliotecas `requests` y `BeautifulSoup` mediante un caso práctico: extraer datos de un directorio de empresas y comercios del Ayuntamiento de Gelida (Barcelona).
## Background
**¿Qué es el Scraping Web?**
El scraping web es el proceso de recopilar datos estructurados de sitios web de manera automatizada. Es ampliamente utilizado en la recopilación de datos, el análisis competitivo, la investigación de mercado, entre otros.
**Herramientas Utilizadas**
- **Python**: Un lenguaje de programación versátil y fácil de aprender.
- **Requests**: Una biblioteca de Python para realizar peticiones HTTP de manera sencilla.
- **BeautifulSoup**: Una biblioteca que facilita el análisis de documentos HTML y XML, permitiendo extraer datos de manera eficiente.
## Hands On:
El script de Python realiza scraping del directorio web de comercios y empresas del pueblo de Gelida (Barcelona) y extrae información relevante. Aquí está el código completo:
```
import requests
from bs4 import BeautifulSoup
def scrape_directory(url, page_number):
# Modificar la URL para incluir el número de página
page_url = f"{url}?pag={page_number}"
response = requests.get(page_url)
soup = BeautifulSoup(response.text, 'html.parser')
comercios = []
ul = soup.find("ul", class_="clear articlelist default")
if ul:
for li in ul.find_all("li"):
tpl_default = li.find("div", class_="tplDefault")
if tpl_default:
subtitle_element = tpl_default.find("a", class_="subtitle")
if subtitle_element:
comercio_info = subtitle_element.text.strip()
comercios.append({
"info": comercio_info
})
return comercios
# URL base del directorio
base_url = "https://www.gelida.cat/el-municipi/empreses-i-comercos"
# Número total de páginas a recorrer
total_pages = 7
# Recorrer todas las páginas y extraer la información
all_comercios = []
for page in range(1, total_pages + 1):
comercios = scrape_directory(base_url, page)
all_comercios.extend(comercios)
contador = 0
# Imprimir los resultados para verificar
for comercio in all_comercios:
print(comercio)
contador += 1
print(f"En total hay {contador} comercios")
```
El script se divide en varias partes clave:
**1.Importación de Bibliotecas**: Se incluyen las bibliotecas necesarias para el proceso de scraping.
```
import requests
from bs4 import BeautifulSoup
```
**2.Definición de la Función scrape_directory**:
- Parámetros: url (URL del directorio), page_number (número de página a analizar).
- Proceso: Modifica la URL, usa `requests` para una petición HTTP, y analiza el contenido HTML para extraer datos utilizando `BeautifulSoup`.
```
def scrape_directory(url, page_number):
page_url = f"{url}?pag={page_number}"
response = requests.get(page_url)
soup = BeautifulSoup(response.text, 'html.parser')
```
**3.Bucle para Recorrer Páginas**:
- Se define la URL base y el número total de páginas.
- Se itera sobre cada página, extrayendo y acumulando la información de los comercios.
```
comercios = []
ul = soup.find("ul", class_="clear articlelist default")
if ul:
for li in ul.find_all("li"):
tpl_default = li.find("div", class_="tplDefault")
if tpl_default:
subtitle_element = tpl_default.find("a", class_="subtitle")
if subtitle_element:
comercio_info = subtitle_element.text.strip()
comercios.append({
"info": comercio_info
})
return comercios
```
En nuestro directorio, si inspeccionamos los elementos de la web tenemos que buscar un `ul` con una clase específica. Luego iteramos sobre cada `li` para extraer datos de los comercios y almacenamos la información en una lista.
**Ejecución y Resultados**
- El script se ejecuta para recorrer el número total de páginas especificadas, recopilando datos de cada comercio.
- Al final, se imprime la información recopilada y se muestra el número total de comercios encontrados.
```
# URL base del directorio
base_url = "https://www.gelida.cat/el-municipi/empreses-i-comercos"
# Número total de páginas a recorrer
total_pages = 7
# Recorrer todas las páginas y extraer la información
all_comercios = []
for page in range(1, total_pages + 1):
comercios = scrape_directory(base_url, page)
all_comercios.extend(comercios)
contador = 0
# Imprimir los resultados para verificar
for comercio in all_comercios:
print(comercio)
contador += 1
print(f"En total hay {contador} comercios")
```
## Conclusión
El ejemplo proporcionado muestra el poder y la flexibilidad de Python para el scraping web. Mediante `requests` y `BeautifulSoup`, podemos acceder y extraer datos de sitios web de manera eficiente. Este conocimiento abre puertas a numerosas aplicaciones en diversos campos como el análisis de datos, el marketing digital y mucho más. Es importante recordar siempre respetar las políticas de uso de los sitios web y las leyes de protección de datos al realizar scraping.

DynamoDB é um banco de dados não relacional totalmente gerenciado pela AWS. Isso significa que, você não precisará ter preocupações relacionadas à escalabilidade e disponibilidade do seu banco de dados. A AWS assume a responsabilidade por esses aspectos, permitindo que você se concentre exclusivamente nas necessidades específicas do seu sistema.
# Conceitos básicos
O DynamoDB armazena dados em uma estrutura de documentos, que são salvos como JSON, proporcionando flexibilidade na adição de novos campos conforme necessário.
Para indexar os registros, o DynamoDB utiliza uma combinação de `partition_key` e `sort_key`. A partition_key define um atributo usado para separar itens, agrupando itens com a mesma chave de partição. Essa chave também é conhecida como primary_key ou HASH. Já a sort_key é um atributo opcional usado para ordenar itens que compartilham a mesma chave de partição, também chamada de RANGE ou range key.
# Consistência de leitura
O DynamoDB armazena três réplicas da sua base de dados em regiões geograficamente distintas. Para garantir que, ao realizar uma leitura, você obtenha a versão mais atual dos dados, o DynamoDB oferece dois níveis de consistência de leitura: consistência eventual e consistência forte.
Operações realizadas com consistência eventual permitem que consultas retornem dados que ainda não foram totalmente propagados para todas as regiões; em contrapartida, esse modo oferece uma latência menor. Por outro lado, operações realizadas sob o regime de consistência forte garantem que os dados lidos sejam os mesmos em todas as regiões, embora a latência dessas operações seja maior.
A escolha entre esses níveis de consistência é muito importante e deve ser feita levando em consideração as especificidades da sua aplicação.
# Conclusão
Em resumo, o DynamoDB destaca-se como uma ótima ferramenta que resolve muito bem os problemas que se propõe.
Nos próximos artigos, continuaremos desbravando as fascinantes possibilidades que o DynamoDB proporciona.

1,711,966 | Interview: Can You Stop “forEach” in JavaScript? | In JavaScript, the forEach method is used to iterate over elements in an array, and it doesn't have a... | 0 | 2023-12-29T18:32:10 | https://dev.to/ajeet321/interview-can-you-stop-foreach-in-javascript-1jle | In JavaScript, the `forEach` method is used to iterate over elements in an array, and it doesn't have a built-in mechanism to stop or break out of the loop prematurely. The `forEach` method is designed to iterate through all elements of the array, and it will continue execution until all elements have been processed.
If you need the ability to stop or break out of a loop under certain conditions, you might consider using a `for` loop or the `for...of` loop instead. Unlike `forEach`, these loops allow you to use the `break` statement to exit the loop when a specific condition is met.
Here's an example using a `for...of` loop:
```
```javascript
const array = [1, 2, 3, 4, 5];
for (const element of array) {
console.log(element);
// Add a condition to break out of the loop
if (element === 3) {
break;
}
}
```
```
In this example, the loop will terminate when the element is equal to 3. This [provides ](https://newsllytoday.com/is-kisskh-me-down/)more flexibility than the `forEach` method when you need to control the flow of the loop based on certain conditions.
Keep in mind that using `break` in this way is not considered good practice in functional programming, and it may be better to use methods like `every`, `some`, or traditional `for` loops for more complex control flow requirements. | ajeet321 | |
1,712,084 | Avoid Tutorial Hell: Choosing Great Learning Resources 🧠 | After setting learning goals (see my previous post), you're ready to fire up YouTube and start... | 25,889 | 2023-12-30T16:22:00 | https://dev.to/brian_curricular/avoid-tutorial-hell-choosing-great-learning-resources-215c | beginners, learning, webdev | After setting learning goals (see my [previous post](https://dev.to/brian_curricular/crafting-better-learning-goals-5b4e)), you're ready to fire up YouTube and start learning, right?
Not so fast! :warning:
There are many excellent free or inexpensive learning resources out there. But frankly, there's also a lot of garbage out there.
It's easy to get stuck in tutorial hell - the endless cycle of watching tutorials without being able to actually do anything with the knowledge. It's critical to do some research and find the right courses, books, or tutorials.
And yet, while the internet is full of recommendations and reviews, I've found you also have to be careful taking someone's advice. Most reviews are way too short ("good course, five stars") and lack helpful context. Most of the time, you don't know someone's learning goals, prior knowledge, or how they supplemented their learning.
That's why I created [Curricular](https://curricular.dev/), to help developers find great courses, with trustworthy recommendations backed by in-depth research and testing.
Our goal is to help 1 million developers level up their career.
At Curricular, we [curate lists of the best courses](https://curricular.dev/guides/) to learn any technical skill. Our recommendations come from hours of research and in-depth testing, and we write detailed reports about our methodology and findings.
We also provide free personalized learning recommendations (seriously - ask us anything, we're glad to help).
### Choosing a Great Course
Here are some lessons from our course evaluation framework to help you choose a great course.
> A great course is one that's built intentionally using the right teaching methods / learning styles for the material, is taught at the target student's level, and delivers its stated objectives.
When choosing a course, you should look for the following:
- was the course created for someone with my learning goals and current level of knowledge?
- does the course list tangible learning outcomes?
- does the course seem to promise too much? (e.g. "everything you'll need to become a professional developer!" -- avoid at all costs)
- does the course offer hands-on practice opportunities - either in-browser coding or solo practice projects?
Where possible, you also want to evaluate the instructor. First, you want to make sure they know what they're talking about. Are they qualified to teach the material? You want to see that their explanations are clear, and that in demonstrations, they show you how things work, rather than just tell you how they work. Look for samples you can preview, and reviews that talk specifically about their expertise.
### Don't Ignore the Prerequisites
Before starting a course or tutorial, make sure you’re ready. Check the prerequisites and evaluate your skill level.
If you don't have the right prerequisite knowledge, you might struggle to learn the topic.
For example: lots of people want to learn React. It's still one of the hottest libraries. But if you're not solid with JavaScript foundations, you're going to have a hard time learning React, since so much of React is writing plain old JavaScript.
This might be tough to hear. We all have limited time to learn. And how do you know when you know enough to move to the next concept?
I'm not saying you have to feel solid with every prerequisite that you find. If that were the case, we'd never get anywhere.
But at the very least, be aware of a course's prerequisites and be honest with yourself about your comfort level with the concepts. If you're feeling fuzzy about too many of the prerequisites, you may need a bit more practice before getting started.
### Mix and Match and Supplement with Solo Practice
Very few courses offer literally everything you'll need to master a topic - that is, to get to professional proficiency with a language or framework.
That's why most of our recommendations at [Curricular](https://curricular.dev/) are learning paths rather than single courses.
You should plan to take several courses (or books) to learn a topic.
And you should also plan to supplement with a practice project to solidify your knowledge. What I mean by this is take on a project without guidance; build something yourself using the technologies you've learned. Practicing with a solo project will test your skills and show you where you need to keep studying.
And try to get feedback on your projects from a more experienced developer. They'll help you spot areas for improvement and where you've missed best practices.
Unfortunately, very few courses and platforms offer grading or feedback on projects, with Scrimba and Udacity being the main exceptions.

My question is what is the convention for watching the return value of a method in react-native? I would like to be able to alter my UI in case the method evaluates to either true/false.
I've provided my setup below. As you can see, as an example, I would like my view to show "Hello" if isFocused evaluates to true and "Hi" if false however this implementation does not obviously won't work for what I'm trying to do

Documentation is extremely valuable for both open source and internal company projects. With that in mind the question arises on what exactly needs to be documented. While code docs generated from inline formats (ex. python doc strings) may be what is considered to be documentation for developers, there's more to it than that. In this article I'll be breaking down different kinds of documentation and what gives them value to their target audience. Layout wise I'll start at the lowest level and move upwards.
## Naming Convention Documentation
First off is the naming of variables and functions which drive the code. A common mistake for newer developers is having code with a lot of inline comments. Much of these verbose comments could be addressed by simply having a naming convention which provides clarity on what the purpose of the function or variable is. As an example:
- `isAddressPOBox()`
- `Address.isPOBox()`
- `ec2_boto_client`
The first and second example shows how naming can change between context. Meanwhile `ec2_boto_client` could be useful if you're dealing with multiple boto clients connecting to the AWS API. Something to note here is that `isAddressPOBox()` could technically just be `isPOBox` but I find that the verbose version also gives context on the input. I would say that you want to get into the habit of doing this for even personal pet projects. It's also very valuable in team environments to make code easier to read (and potentially faster PRs).
## Typing Documentation
Typing is useful for giving hints on function input and output. While this is default for statically typed languages, some dynamic languages such as python may support type hinting features for this particular purpose:
```python
def average_numbers(numbers: list[int]) -> float:
```
In this example I know I need to provide a list of integers as input and will obtain a float as output. You will want to be careful on how you organize custom types. A lack of organization can lead to a lot of back and forth on source code reading. Another nice benefit of typing is that it can be used by many IDEs to enhance linting features by seeing if inputs and outputs match the requested types. This is useful for cases where your project is a dependency library as well as working on team environments.
## Comment Documentation
Documentation through code comments can be useful in cases where code may rely on complex algorithms or when something is done in an unusual manner. I find most of the code I comment on tends to be related to cryptographic hashing:
```python
).sign(self._key_object, hashes.SHA256())
# SHA256 was chosen here instead of SHA512 as a compromise between decrypt performance and
# hash security
```
In this example I'm explaining the reasoning why I'm using SHA256 to sign a cert when the more powerful SHA512 hash exists. `TODO` comments are a specialized form of comment documentation which allows developers to keep track of code improvements quickly, which can be transitioned to tickets/issues/tasks later on. I will warn on being careful on your ratio of comments to code. At a certain point the actual code becomes difficult to follow and could be a sign that your naming convention/typing might have issues.
## Application Interface Documentation
This style of documentation is often what developers consider to be "code documentation". Users may reference it for libraries to figure out what functions need to be called. Developers may use it to understand the code base. Such documentation is often found after a function/method signature to document inputs, outputs, and a basic summary of what the code does:
```python
def average_numbers(numbers: list[int]) -> float:
"""Average a list of numbers
:param numbers: The list of numbers to average
:type numbers: list[int]
:return: The average of the numbers
:rtype: float
"""
return np.average(numbers)
```
Important to note is that the format of application interface documentation will vary depending on the programming language and documentation solution. If you find that files become too verbose due to application interface documentation it might be a sign of functions trying to do too much or a need for separation refactoring.
## Project README
I would consider this the starting point of figuring out basic information for a project. This includes items such as:
- Why the project was created
- Status of the project
- Project requirements
- How to install the project (or a link to an install guide for more complex projects)
- Basic usage / getting started
- Security policy
- Links to further documentation
- Contact information (filing bug reports, etc.)
A well laid out README can often be a great way to get project adoption as it brings an assumption that the rest of the project is well documented and users will find information they need easily.
## Internals Documentation
This somewhat ties in with application interface documentation. It's general used to supplement such documentation and primarily geared towards developers, power users, and potential contributors to a project. A few examples of internals documentation:
- [Gitea Actions Design Docs](https://docs.gitea.com/usage/actions/design)
- [Kubernetes Helm Architecture](https://v2.helm.sh/docs/architecture/)
- [Python Developer's Guide](https://devguide.python.org/)
In general this type of documentation tends to be useful at larger scale products with wide user adoption. Understanding internals of a project can also help in finding potential performance optimizations or conditions that might cause bugs to occur.
## Process Documentation
This is used to describe various processes a project might have in dealing with the codebase. Some examples of this include:
- How to contribute to a project
- Setting up a development environment
- Project code of conduct (in particular enforcement of it)
- Bug reporting
- Security reporting guidelines (different from basic bug reporting as it tends to be done in a more private manner to avoid early exploits in the wild)
- Release process
It's essentially how users might interact with a project versus how to use the actual project itself. This category of documentation is primarily oriented towards projects with a high contribution rate.
## General Usage Documentation
General usage documentation is geared towards end users of the project. This may replace parts of the README documentation if certain usage details require a substantial explanation. General usage documentation often touches on the following components:
- Downloading the project (source code/package/installer)
- Installing the project
- Configuring the project
- Validating the project (generally in the form of a quick start guide)
Application interface documentation may be included here as well if the project in question is primarily used as a dependency. Smaller projects may combine download, installation, and configuration steps. Larger projects may need them broken out to handle environment variations such as operating systems, package managers, service management, database engines, etc.
## API Documentation
Often used for cases where a project exposes a REST or other type of API service. [Open API](https://spec.openapis.org/oas/latest.html) is a popular method of documenting such API services. It can also be used along side tools such as [Swagger Codegen](https://swagger.io/tools/swagger-codegen/) to produce boilerplate code for API interaction / testing purposes. There may also be support files for popular API testing tools such as [Postman](https://www.postman.com/) or [Insomnia](https://insomnia.rest/). This makes it easier at a glance to see what data is coming back from a call so the user knows how to handle parsing the data.
## Advanced Documentation
General usage documentation works well for covering the standard user needs for the project. Advanced documentation enhances this by showing more advanced setups which are useful but not what you would expect from an out of the box setup. Such documentation could touch on manual configurations that are normally set to developer recommended settings to cover a majority of use cases. Finally there are cases where subject matter expertise is required such as BGB network integration with Kubernetes networking providers. Such documentation is generally recommended for more active projects where the developer is more aware of project use cases.
## External Documentation
This may also be considered "community documentation". Someone writes a blog post on a project, maybe a key note video is posted, essentially anything that isn't directly hosted on core project infrastructure. It may also point to community resources such such as forums, slack channels, and social media sites. One word of caution is that I recommend avoiding slack exclusive documentation for a project as there is a barrier of entry in accessing the information (not to mention separation of concerns).
## Hosting Documentation
Once you have all the documentation worked out a place to host it will be necessary. Some documentation generation may have ties in with specific hosting sites. [Read The Docs'](https://about.readthedocs.com/?ref=readthedocs.com) support for Sphinx and other documentation tools is one example. [GitHub pages](https://pages.github.com/) can be useful for GitHub hosted projects as it integrates well with GitHub Actions CI/CD deployments.
If you want to self host and don't mind paying a bit a combination of Route53 (unless you host DNS elsewhere), S3, and CloudFront on AWS can provide a pretty reliable and cost effective site hosting. It's also a great solution if you're working on an internal company project with architecture hosted on AWS. It's also nice in compliance environments since you can implement strict access controls when necessary which can integrate with company SSO and other IAM components.
Wikis are another solution if your contributors are more comfortable with them. It also helps prevent the issue of "documentation updates caused a big CI run" that can catch some projects off guard. For GitHub users there is a fairly minimal [GitHub Wiki feature](https://docs.github.com/en/communities/documenting-your-project-with-wikis/about-wikis) for projects that support it. This also works on the enterprise versions if you're doing an internally hosted project.
## Conclusion
As someone who has been a proponent of documentation for much of my career, I hope this provides some insight on the depth of documentation you can have for a project. I will say that some types of documentation tend to show their true value at certain project growth stages. Trying to do advanced usage documentation is not ideal when your project is starting out and you don't have enough usage information. With that said I recommend looking over each documentation type and evaluating if it would help with project adoption / contributions. | cwprogram |

1,712,262 | Detect, Defend, Prevail: Payments Fraud Detection using ML & Deepchecks | If you are new to machine learning or have just started, you have come to the perfect place!! Today,... | 0 | 2024-01-13T11:14:00 | https://dev.to/jagroop2001/detect-defend-prevail-payments-fraud-detection-using-ml-deepchecks-4fag | machinelearning, python, scikitlearn, ai | If you are new to machine learning or have just started, you have come to the perfect place!!
Today, we make use of Machine Learning to create a full-fledged Machine Learning project. So, in this project, you will have the opportunity to work with the following technologies and tools:
- **Where we build our model:** Google Colab
- **Data Preprocessing :** Numpy,Pandas.
- **ML Model Creation:** scikit-learn
- **Validation and Testing ML Model:** Deepcheck's Platform.
So now we have the items in our toolbox, but we need a problem statement to show how we will use them to create something wonderful.
So, let's put our technologies to work on developing Online Payment Fraud Detection.
Now we know what we're going to use or what's our ultimate outcome will be. So, let's begin :
**Step 1:** Import libraries which we use in this project :
```
import pandas as pd
import numpy as np
```
**Step 2:** Load Data
So in this project we are using genuine datasets from Kaggle for this project. That dataset is available for download at this link:
[Online Payments Fraud Detection](https://www.kaggle.com/datasets/rupakroy/online-payments-fraud-detection-dataset/data)
The dataset is ready for use when you download it, rename it (if you want), and upload it to Google Colab:
```
df = pd.read_csv('payment_fraud_detection.csv')
df.head()
```
`df.head()` shows us the top 5 results of csv file as shown :
**Step 3:** Get familiar with features
Let's explore the features:
**step:** represents a unit of time where 1 step equals 1 hour
**type:** type of online transaction
**amount:** the amount of the transaction
**nameOrig:** customer starting the transaction
**oldbalanceOrg:** balance before the transaction
**newbalanceOrig:** balance after the transaction
**nameDest:** recipient of the transaction
**oldbalanceDest:** initial balance of recipient before the transaction
**newbalanceDest:** the new balance of recipient after the transaction
**isFraud:** fraud transaction
**Step 4:** Data Cleaning
There are numerous steps involved in the data cleansing process, but we will focus on the most crucial ones here, which are as follows:
- Eliminating null data
- Eliminating rows which doesn't affect if payment is fraud or not.
Let's check is there any null data available using :
```
df.isnull().sum()
```
We can clearly see that, there is null data available here :
We can handle this in 2 ways :
- Dropping that rows from our dataset ( Not preferable if percentage of null data is more than 1%)
- Replace null with the mean or median value for numerical data and for categorical data we can use mode.
In the record `isFraud` is our output variable which is used to check if payment is fraud or not so we can't put any average here also the amount of data is less than 1% so we can drop that using :
```
df = df.dropna(subset=['newbalanceDest', 'isFraud', 'isFlaggedFraud'])
```
**Now let's check which rows doesn't affect our results if we remove that :**
On careful consideration, we have find it out these fields `'isFlaggedFraud','nameOrig','nameDest'` doesn't affect to check if payment is fraud or not. So let's remove that :
```
df.drop(['isFlaggedFraud','nameOrig','nameDest'], axis = 1, inplace = True)
```
After running that code let's again check our dataframe(df) head using `df.head()` :
**Step 5:** Convert Categorical Data into Numerical Data
After careful observation we have found that, only `type` is non-numerical column. So let's check how many value count it have :
```
df["type"].value_counts()
```
We can clearly see that it have 5 unique values as :
let's encode this into numerical data :
```
data = pd.get_dummies(df, columns=['type'], drop_first=True)
data.head()
```
The modified data now appears as follows:
**Step 6 :** Split Features and Target values :
Features : It represents the input variables
Target : It represents output variables.
As it is understood in supervised machine learning, input and output variables must be supplied to the model in order for it to use what it has learned from the dataset to predict future values.
From dateset we can clearly identified that `isFraud` is Target Variables and remaining columns are Features.
So let's spit that :
```
X = data.loc[:, data.columns.difference(['isFraud'])].values
y = data.loc[:,"isFraud"].values
```
**Step 6:** Split Data into Training and Test Set.
We divide data into training and test sets primarily so that we can use the training data to train our machine learning model and the test data to confirm whether or not the model has been trained correctly.
**This can be easily done using scikit-learn :**
```
from sklearn.model_selection import train_test_split
X_train,X_test,y_train,y_test = train_test_split(X,y,test_size= 0.3, random_state = 42)
```
Here `test_size` represents the amount of test data we want so here I want 30% as test data from the entire dataset and this `train_test_split` method will select 30% of test data randomly from dataset.
`random_state` represents every time we want the same data for training and test set. So this will split data randomly but every time we will run that project or share it to someone this randomness will remains same in that conditions.
**Step 7:** Training ML Model
This is the main part of our project where we actually building our ML models.
From Target variables we can identify that the result will be either `fraud` or `notFraud`. So here we apply classification algorithm.
There are couple of Classification algorithms are available but here we will be using 1 model which is `RandomForestClassifier`
**NOTE :** _As an assignment one can try out different algorithms and pick best out of it._
Let's apply the algorithm using scikit-learn :
```
from sklearn.ensemble import RandomForestClassifier
rf = RandomForestClassifier()
rf.fit(X_train,y_train)
```
Our model is ready for evaluation :
**Step 8:** Model Evaluation
This is a very vital and critical step where we can determine whether our model is ready for use or still need some adjustments.
In the past, writing a tonne of additional code was required for our model's evaluation. However, the [Deepchecks](https://deepchecks.com/) platform offers us the current solutions that the world needs today.
With [Deepchecks](https://deepchecks.com/), you can completely verify your data and models from research to production, providing an all-inclusive open-source solution for all your AI & ML validation needs.
**The Deepcheck's features that businesses enjoy the most are listed below:**
**Evaluation of Data Quality:**
- Finding data that is inconsistent or missing.
- Finding abnormalities and outliers in the dataset.
**Validation of the Model:**
- Examining the fairness and bias of the model.
- Analysing the model's performance using several metrics.
- Ensuring the model's stability and ability to adapt well to fresh data.
**Interpretability and Explainability:**
- Supplying clarification on model predictions to improve comprehension.
- Displaying the contribution of features to predictions and their relevance.
**Integration and Automation:**
- Streamlining the model deployment process by automating the validation procedure.
- Integration with widely used deep learning technologies and frameworks.
**Let's Integrate it in our platform :**
The integration procedure only consists of two steps:
- Install the library.
- Copy the code directly from the documentation, adjust the settings, and you're good to go.
There are lot's of solutions provided here, so today we are using for evaluation of our model. Also we have structured data ( csv format) so we use their Tabular Section.
Let's install :
```
pip install deepchecks --upgrade
```
After successful installation, let's utilise this to check our model validation. Also one can directly jump into [this documentation](https://docs.deepchecks.com/stable/tabular/auto_tutorials/quickstarts/plot_quick_model_evaluation.html) and try by oneself to integrate it into our project or follow along with me.
- **Let's Create Deepchecks Dataset Object**
```
from deepchecks.tabular import Dataset
train_ds = Dataset(X_train, label=y_train, cat_features=[])
test_ds = Dataset(X_test, label=y_test, cat_features=[])
```
- **Let's Evaluate our model:**
```
from deepchecks.tabular.suites import model_evaluation
evaluation_suite = model_evaluation()
suite_result = evaluation_suite.run(train_ds, test_ds, rf)
suite_result.show()
```
**It shows us results as :**
**Let's explore our model's evaluation :**
In `Didn't Pass` section. It explains us it didn't pass some validations during Train-Test Split and it may affect our model.
No worries we can easily resolve this using [Deepchecks Train Test Validation Suite](https://docs.deepchecks.com/stable/tabular/auto_tutorials/quickstarts/plot_quick_train_test_validation.html).
This is an exercise for the viewers to integrate it and check this with this our `Didn't Pass` test clear's. I am sure it surely clear with this.
**Let's explore our Passed Section:**
In the passed section it provides us lot's of information which we are manually doing by writing code but this platform provides us in literally 5-6 lines of code.
- **Test case report :**
- **Our ROC Curve Plot :** It also provide explanation as well that why I loves this platform.
- **Prediction Drift Graph :**
- **Simple Model Comparison:**
- **Most Important Confusion Matrix :**
There are many more items in that report that I haven't included here, but if you follow the code with this, I strongly advise you to verify this throughout your evaluation.
Also if you have any confusion related to it. You can directly go to their discussion section in [github](https://github.com/deepchecks/deepchecks/discussions) :
With over 3.2K ratings in this repository, [Deepcheck](https://github.com/deepchecks/deepchecks) offers excellent assistance.
That’s all in this blog. One can also fine-tune this model or even use different algorithms and create personalized ML/AI models. 🤖🧠✨
