Consultation: It's crucial to consult with a healthcare provider before starting Vidalista to determine the appropriate dosage and ensure it's safe based on individual health conditions and other medications.
Safety Considerations
Side Effects: While generally well-tolerated, Vidalista may cause mild side effects such as headaches, dizziness, or digestive issues in some individuals. Serious side effects are rare but should be promptly reported to a healthcare provider.
Allergies: Ensure there are no allergies to Tadalafil or any other ingredients present in Vidalista before use.
## **Lifestyle Recommendations**
Healthy Lifestyle: Maintaining a healthy diet and regular physical activity can complement the benefits of Vidalista by promoting overall well-being and supporting cardiovascular health.
Moderate Alcohol Use: Avoid excessive alcohol consumption when using Vidalista, as it may reduce the medication's effectiveness and increase the likelihood of side effects.

Utilizing high-level algorithms, these bots assist the traders in exploiting the gap between the various exchanges. In this article, let us discuss building high-frequency triangular arbitrage bots to make the business people and other entrepreneurs understand the process with ease.
**Understanding Triangular Arbitrage**
Triangular arbitrage consists of exchanging three different cryptocurrencies with the intent to profit from the difference in their prices. For instance, if the exchange rates of Bitcoin, Ethereum, and Litecoin vary across different platforms, a triangular arbitrage bot can buy the first currency and sell it in the second, before converting the obtained proceeds into the third currency for a profit. This strategy is very efficient and can bring in large amounts of cash with a relatively small amount of risk.
**Importance of High-Frequency Trading**
High-frequency trading (HFT) can be defined as the execution of a large number of trades in fractions of a second. HFT is very important in the context of triangular arbitrage because the price differences may not take long to exist. This is because by using HFT, traders will be able to exploit these opportunities in the shortest time possible thus maximizing on the returns that are made. The integration of HFT and triangular arbitrage results in a highly effective weapon for investors.
**Role of Advanced Algorithms**
Algorithms are the core of high-frequency triangular arbitrage bots. These algorithms scan data from multiple exchanges simultaneously in real-time and look for profitable trades. They perform trades at the speed of light to make sure that the traders can capitalize on price discrepancies as small as possible. These algorithms increase the bot’s performance and profitability because they are constantly being updated to reflect market conditions.
**Developing a Triangular Arbitrage Bot**
**Data Collection**
The first procedure of creating a triangular arbitrage bot involves data gathering. This entails capturing of real time price information from different crypto markets. APIs (Application Programming Interfaces) are used in this case to enable the bot to view and analyze real-time market data.
**Algorithm Development**
After that, developers design the set of rules for the bot to follow while making trading decisions. These algorithms have to be able to find profitable arbitrage opportunities within milliseconds. They should also be capable of processing big data and making trades in a short time.
**Testing and Optimization**
It is imperative that the bot undergoes several tests before it is officially released. This consists of training the bot using past data to check its proficiency under varying market conditions. Developers also adjust the algorithms for the most accuracy and the fastest speed for the bots to provide the most revenue.
**Deployment and Monitoring**
When the bot is fully tested and fine-tuned, it can then be used for actual trading. It is important to constantly supervise the operation of the bot and to make necessary adjustments based on market trends. It should also be said that the bot requires regular updates and maintenance in order to work flawlessly.
**Conclusion**
Constructing high-frequency triangular arbitrage bots with sophisticated algorithms is an innovation for those engaged in cryptocurrency trading. The concept of utilizing these bots means approaches an optimal risk-reward ratio that can bring tremendous benefits. It can be suggested that such bots can offer a competitive advantage to any business person or an entrepreneur who aims to trade or invest in the world of cryptocurrencies.

As sales teams strive to meet targets and outpace competitors, having the right sales content at their fingertips can be the difference between closing a deal and losing a prospect. This article delves into the importance of sales content management, its benefits, and strategies for implementation.
## Understanding Sales Content Management
Sales content management involves the systematic organization, storage, and distribution of sales materials, including presentations, brochures, case studies, white papers, and other resources that support the sales process. This approach ensures that sales teams have access to the most relevant, up-to-date, and high-quality content whenever they need it.
## The Importance of Sales Content Management
**Improved Efficiency and Productivity
**
Sales representatives spend a significant portion of their time searching for and customizing content. An effective **[sales content management](https://salesier.com/solution/sales-ai-content-management.html
)** system can drastically reduce this time, allowing reps to focus more on selling and less on administrative tasks.
Consistency and Accuracy
Consistent messaging is crucial for building trust and credibility with prospects. A centralized sales content management system ensures that all team members are using the latest, approved versions of materials, maintaining brand consistency and reducing the risk of misinformation.
Enhanced Collaboration
Sales content management facilitates better collaboration between marketing and sales teams. Marketing can create and update content based on real-time feedback from sales, ensuring materials are always relevant and effective.
Data-Driven Insights
Advanced sales content management systems often come with analytics capabilities, allowing businesses to track the usage and effectiveness of various pieces of content. These insights can guide future content creation and strategy adjustments.
Key Components of Sales Content Management
Content Repository
A centralized repository where all sales materials are stored. This repository should be easily accessible, searchable, and organized logically, often categorized by sales stage, product line, or customer segment.
## Content Personalization Tools
Tools that allow sales reps to customize content for specific prospects or situations without altering the core message or brand guidelines.
Content Distribution Channels
Efficient methods for delivering content to sales reps, whether through a web portal, mobile app, or direct integration with CRM systems.
Analytics and Reporting
Features that track which content is being used, how often, and its impact on sales outcomes. These metrics help in refining content strategies and demonstrating the ROI of content investments.
Implementing Sales Content Management
Assess Current State
Evaluate your existing sales content and processes. Identify gaps, redundancies, and opportunities for improvement. Understand the needs of your sales team and the types of content that are most effective at different stages of the sales cycle.
Choose the Right Platform
Select a sales content management platform that aligns with your business needs. Key considerations include ease of use, integration capabilities with other systems (e.g., CRM), and the ability to scale as your business grows.
**Develop and Organize Content
**
Create a content strategy that aligns with your sales goals. Organize content into categories that make it easy for sales reps to find what they need. Ensure all content is high-quality, up-to-date, and tailored to your target audience.
Train Your Team
Provide thorough training on how to use the sales content management system. Ensure that sales reps understand how to access, customize, and distribute content effectively. Encourage feedback to continuously improve the system.
Monitor and Optimize
Regularly review analytics to understand what content is working and what isn’t. Use these insights to refine your content strategy and improve the overall effectiveness of your sales content management system.
Best Practices for Effective Sales Content Management
Keep It Simple
A complex system can hinder rather than help. Aim for a user-friendly platform that makes it easy for sales reps to find and use content.
Ensure Content Quality
Regularly update and audit your content to ensure it remains relevant, accurate, and engaging. High-quality content reflects positively on your brand and can significantly influence purchasing decisions.
Foster Collaboration
Encourage continuous collaboration between sales and marketing teams. Sales reps should provide feedback on content effectiveness, while marketing should be responsive to these insights.
Leverage Technology
Utilize AI and machine learning to personalize content recommendations based on the sales rep’s past behavior and the specific needs of prospects. Automation can also streamline content updates and distribution.
**Measure Success
**
Establish clear metrics for success and regularly evaluate your sales content management system against these benchmarks. Adjust your strategies based on data-driven insights to continuously improve performance.
In Conclusion, Effective sales content management is a cornerstone of successful sales strategies. By providing sales teams with easy access to high-quality, relevant content, businesses can enhance productivity, ensure consistency, and drive better sales outcomes. Implementing a robust sales content management system requires careful planning, collaboration, and ongoing optimization, but the benefits it brings in terms of efficiency, collaboration, and ROI make it a worthwhile investment.
As the business landscape continues to evolve, so too will the demands on sales teams and the content they use. Staying ahead of these changes through strategic sales content management will position your organization for long-term success in an increasingly competitive market. | luke_warner_f8e11a728b516 |

def get_resource():
return jsonify({'message': 'Hello, World!'})
if __name__ == '__main__':
app.run(debug=True)
```
5. Blockchain Technology
Blockchain is transforming industries by providing decentralized, secure, and transparent transaction systems. It is no longer confined to cryptocurrencies but is being used in supply chain, healthcare, and more.
Example: Simple Smart Contract with Solidity
```
pragma solidity ^0.8.0;
contract HelloWorld {
string public message;
constructor() {
message = "Hello, World!";
}
function setMessage(string memory newMessage) public {
message = newMessage;
}
}
```
6. Cybersecurity
As cyber threats become more sophisticated, robust cybersecurity measures are essential. This includes adopting zero-trust models, using AI for threat detection, and emphasizing secure coding practices.

# Generate a key
key = Fernet.generate_key()
cipher_suite = Fernet(key)
# Encrypt a message
message = b"Hello, World!"
cipher_text = cipher_suite.encrypt(message)
# Decrypt the message
plain_text = cipher_suite.decrypt(cipher_text)
print(f"Cipher Text: {cipher_text}")
print(f"Plain Text: {plain_text.decode()}")
```
7. Quantum Computing
Quantum computing is set to revolutionize problem-solving in areas like cryptography, material science, and complex system simulations. While still in its infancy, it's a trend worth watching.
Example: Quantum Circuit with Qiskit
```
from qiskit import QuantumCircuit, transpile, Aer, execute
# Create a Quantum Circuit
qc = QuantumCircuit(1, 1)
qc.h(0)
qc.measure(0, 0)
# Simulate the Quantum Circuit
simulator = Aer.get_backend('qasm_simulator')
compiled_circuit = transpile(qc, simulator)
result = execute(compiled_circuit, simulator).result()
# Get the result
counts = result.get_counts()
print(f"Counts: {counts}")
```

1,922,129 | Understanding the Difference Between `Array<T>` and `T[]` in TypeScript | In TypeScript, arrays are a fundamental part of the language, allowing developers to store... | 0 | 2024-07-13T10:20:24 | https://coleruche.com/post/understanding-the-difference-between-arrayt-and-t-in-typescript | typescript, webdev, javascript | In TypeScript, arrays are a fundamental part of the language, allowing developers to store collections of values of a specific type. There are two primary ways to define arrays: `Array<T>` and `T[]`. While they are often used interchangeably, there are subtle differences between the two that are worth understanding. This article will delve into these differences and provide guidance on when to use each form.
## What are `Array<T>` and `T[]`?
- **`Array<T>`**: This is a generic type provided by TypeScript. It signifies an array where each element is of type `T`.
- **`T[]`**: This is a shorthand notation for the `Array<T>` type. It also represents an array where each element is of type `T`.
## Syntax Differences
The primary difference between `Array<T>` and `T[]` lies in their syntax. Here’s a quick comparison:
```typescript
// Using Array<T>
let numbers: Array<number> = [1, 2, 3, 4];
// Using T[]
let numbersAlt: number[] = [1, 2, 3, 4];
```
## Type Readability
In some cases, `Array<T>` can improve readability, especially when dealing with more complex types. Consider the following example:
```typescript
// Using Array<T>
let arrayOfArrays: Array<Array<number>> = [[1, 2], [3, 4]];
// Using T[]
let arrayOfArraysAlt: number[][] = [[1, 2], [3, 4]];
```
While both notations are correct, `Array<Array<number>>` might be clearer in showing that the type is an array of arrays of numbers, whereas `number[][]` can sometimes be harder to parse visually.
## Consistency with Other Generic Types
Using `Array<T>` can also be more consistent with other generic types in TypeScript. For instance, if you’re already using generics for other types like `Promise<T>` or `Map<K, V>`, it might make sense to use `Array<T>` for consistency:
```typescript
let promises: Array<Promise<number>> = [Promise.resolve(1), Promise.resolve(2)];
```
## Function Signatures
When defining function signatures, both `Array<T>` and `T[]` can be used interchangeably. However, in more complex generic functions, `Array<T>` might be preferred for clarity:
```typescript
// Using Array<T>
function getFirstElement<T>(arr: Array<T>): T | undefined {
return arr[0];
}
// Using T[]
function getFirstElementAlt<T>(arr: T[]): T | undefined {
return arr[0];
}
```
## Compatibility and Preferences
Both `Array<T>` and `T[]` are fully compatible with each other. It ultimately comes down to personal or team preference. Some developers prefer the concise `T[]` notation, while others favor the explicit `Array<T>` syntax for its readability and consistency.
## Conclusion
In summary, `Array<T>` and `T[]` in TypeScript are two ways to define arrays, with subtle differences in syntax and readability. Both are equally valid and compatible, so choosing one over the other often comes down to personal preference or the need for consistency with other generic types.
Understanding these differences can help you write clearer, more maintainable TypeScript code. Whether you opt for `Array<T>` or `T[]`, the key is to stay consistent with your choice across your codebase.
Happy coding!

1,922,151 | Testing Components In Angular: NO ERRORS SCHEMA, Stub Components, and NgMocks | When we need to write a test for components, it is not hard. The pain starts when our components... | 0 | 2024-07-13T10:21:30 | https://www.danywalls.com/testing-components-in-angular-noerrorsschema-stub-components-and-ngmocks | When we need to write a test for components, it is not hard. The pain starts when our components begin to have dependencies, not only in the constructor or in the TypeScript file. The real challenge comes when we start to add dependencies of other components, and these components have other dependencies like directives, external libraries, or forms.
In that moment is when we really start to invoke the dark forces to help us survive, and you don't know who answers your question, but some solutions come to your mind `NO_ERRORS_SCHEMA` , Stub Component and NgMocks
Every option can help you solve the problem, but do you know the hidden cost? Today we are going to learn how to test components with children and how to handle that situation. As always, the best way to learn is with a scenario.
## Scenario
We have an Angular application working with modules (yes, we have many companies using modules in 2024). It shows a list of products on offer, using two components: `ProductComponent` and `ProductsListComponent`.
The `ProductComponent` uses `ProductsListComponent` to show the list of products and its `kendo-viewlist` inside working but without tests. 🤪
Your goal is to add test coverage to the `ProductsComponent`, but keep in mind its dependencies:
* Use the `products.service` to get the total number of products on offer.
* The `product-list.component` which uses `kendo-listview`.
Sounds not hard to do, so let's run the test.
## Running Tests
We know Angular generates [default tests for our application](https://www.telerik.com/blogs/testing-angular),it takes care of the `ProductsComponent`, so let's open the products-component.ts; it doesn't look complex.
```typescript
import { Component, inject } from '@angular/core';
import { ProductsService } from '../services/products/products.service';
@Component({
selector: 'app-products',
templateUrl: './products.component.html',
styleUrl: './products.component.css',
})
export class ProductsComponent {
productService = inject(ProductsService);
total$ = this.productService.totalProductsInOffer;
}
```
In the template, there isn't much. It gets the total products from the service and shows the `ProductListComponent`. Perfect.
```html
<div class="bg-white">
<div
class="mx-auto max-w-2xl px-4 py-16 sm:px-6 sm:py-24 lg:max-w-7xl lg:px-8"
>
@if (total$ | async; as totalProducts) {
<h2 class="text-2xl font-bold tracking-tight text-gray-900">
We have {{ totalProducts }} in offers
</h2>
}
<app-products-list/>
</div>
</div>
```
The test should be simple, let's open the `products.component.spec.ts` and check if it can create an instance. This should be a task to solve in 2 minutes. Let's run the `ng test`.
```typescript
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ProductsComponent } from './products.component';
describe('ProductsComponent', () => {
let component: ProductsComponent;
let fixture: ComponentFixture<ProductsComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
declarations: [ProductsComponent],
}).compileComponents();
fixture = TestBed.createComponent(ProductsComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
```
and... tada!!! 😭 I started to get weird errors:
```plaintext
NullInjectorError: R3InjectorError(DynamicTestModule)[ProductsService -> HttpClient -> HttpClient]:
```
### Why NullInjectorError ?
Maybe you ask your self why there's a null injector error when my component is working? I provide my service, but the `ProductsComponent` is now living in the sandbox of `TestBedTestingModule`.
Angular declares the `ProductService` for us, but we are not providing the `HttpClientModule`. Instead, we use the `HttpClientTestingModule` so so let's import it.
```typescript
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ProductsComponent } from './products.component';
import { HttpClientTestingModule } from '@angular/common/http/testing';
fdescribe('ProductsComponent', () => {
let component: ProductsComponent;
let fixture: ComponentFixture<ProductsComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
declarations: [ProductsComponent],
}).compileComponents();
fixture = TestBed.createComponent(ProductsComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
```
Save the changes, everything should work, let's see 😭
```bash
Error: NG0304: 'app-products-list' is not a known element (used in the 'ProductsComponent' component template):
1. If 'app-products-list' is an Angular component, then verify that it is a part of an @NgModule where this component is declared.
2. If 'app-products-list' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
```
We got another error! Why does the `products-component` complain about `app-products-list`? Well, we are making a reference to it, and Angular wants to resolve it. Or we can try to focus on our test and ignore that point 😈 by using `NO_ERRORS_SCHEMA`.
## NO\_ERRORS\_SCHEMA
😈 We want to finish our task of testing our component, so the great idea is to use `NO_ERRORS_SCHEMA` imported from `@angular/core`. Using `NO_ERRORS_SCHEMA` tells the Angular compiler to ignore unrecognized elements and attributes in your templates and mark them as HTML elements.
```typescript
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ProductsComponent } from './products.component';
import { HttpClientTestingModule } from '@angular/common/http/testing';
import { NO_ERRORS_SCHEMA } from '@angular/core';
fdescribe('ProductsComponent', () => {
let component: ProductsComponent;
let fixture: ComponentFixture<ProductsComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
declarations: [ProductsComponent],
schemas: [NO_ERRORS_SCHEMA],
}).compileComponents();
fixture = TestBed.createComponent(ProductsComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
expect(component).toBeTruthy();
});
});
```
Save changes. Great! Everything is green!
### 👀 Why I don't recommend NO\_ERRORS\_SCHEMA
When we use `NO_ERRORS_SCHEMA` in our Angular tests, it hides template errors and reduces test coverage. This can lead to false positives and promotes poor code quality, which is a hidden price to pay in the future.
### 🙉 Importing Child Dependencies
If the problem is because the `ProductsListComponent` is not declared in the `TestBed` sandbox, why not import it? Let's do it.
```typescript
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ProductsComponent } from './products.component';
import { HttpClientTestingModule } from '@angular/common/http/testing';
import { ProductsListComponent } from '../components/products-list/products-list.component';
fdescribe('ProductsComponent', () => {
let component: ProductsComponent;
let fixture: ComponentFixture<ProductsComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
declarations: [ProductsComponent, ProductsListComponent],
}).compileComponents();
```
And here we go... adding more and more dependencies.
```bash
Chrome 126.0.0.0 (Mac OS 10.15.7) ProductsComponent should load the product-list FAILED
Error: NG0304: 'kendo-listview' is not a known element (used in the 'ProductsListComponent' component template):
1. If 'kendo-listview' is an Angular component, then verify that it is a part of an @NgModule where this component is declared.
f 'kendo-listview' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
error properties: Object({ code: 304 })
```
.. okay, let's fix it by adding the `ListViewModule` from Kendo.
```typescript
import { ProductsComponent } from './products.component';
import { HttpClientTestingModule } from '@angular/common/http/testing';
import { ProductsListComponent } from '../components/products-list/products-list.component';
import { ListViewModule } from '@progress/kendo-angular-listview';
fdescribe('ProductsComponent', () => {
let component: ProductsComponent;
let fixture: ComponentFixture<ProductsComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [HttpClientTestingModule, ListViewModule],
declarations: [ProductsComponent, ProductsListComponent],
}).compileComponents();
```
hold on a second... are we adding dependencies to the `ProductsComponent` test that aren't related to it? What will happen when the `ProductListComponent` changes and adds a form? Will the `ProductComponent` test then require the `FormsModule`? Our test will break due to a change in the `ProductListComponent`.
Do you think this is a good approach, or are we mixing a unit test with an integration test?
I think we should avoid getting too deep into our test. Our responsibility is to ensure that the products work, retrieve the data, and display the number of offers. The responsibility for Kendo stuff lies with the product list. An alternative is to stop here and mock the `ProductList`.
## Stub The Component
We want to replace the real version of `ProductListComponent`. When we create a stub, it's just a class with the same selector as the original component and shares the API implementation interface. Using a stub, we can query it like a child view, adjust the template for our test, and, of course, avoid requiring all those dependencies.
Create a class with the `@Component` decorator and adjust the template. It's like creating a component. The code looks like this:
```typescript
@Component({
selector: 'app-products-list',
template: ` <div>my products</div>`,
})
export class ProductListStub implements ProductsListComponent {
products: Product[] = [];
}
```
Next, replace the `ProductsListComponent` with our stub in the declaration section. The final code looks like this:
```typescript
import { Component } from '@angular/core';
import { Product } from '../services/products/products.service';
@Component({
selector: 'app-products-list',
template: ` <div>my products</div>`,
})
export class ProductListMock implements ProductsListComponent {
products: Product[] = [];
}
describe('ProductsComponent', () => {
let component: ProductsComponent;
let fixture: ComponentFixture<ProductsComponent>;
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [HttpClientTestingModule],
declarations: [ProductsComponent, ProductListStub],
}).compileComponents();
fixture = TestBed.createComponent(ProductsComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
```
## 👀 The Hidden Price of Stub
Well, stubbing the components is very nice because it's an easy way to avoid worrying about the child component dependencies. Of course, we have control over the test, but there is a hidden price to pay.
We must declare every component and maintain these stubs. If you are working on a big product, keeping all stubs updated might be an extra effort that your manager doesn't want to pay for. So, let's find another solution using NgMocks.
## Ng Mocks
`ngMocks` is a powerfull library, it help us to simplify the testing and make it easy to ready and reduce the boilerplate, i love work with it.
NgMocks provides utilities and helpers for Angular unit testing extending `TestBed`, `ComponentFixture` making it simple. We reduce a lot of boiler plate using utilities like like `MockBuilder`, `MockRender`,`MockComponent`, `MockDirective`, `MockPipe`, `MockService`, and `AutoMockModule` and more .
> I don't will get deep about every aspect of ngMock, I recommend checkout the website or if want an article about leave a comment
First install the [ng-mocks](https://ng-mocks.sudo.eu/) library:
```bash
npm install ng-mocks --save-dev
```
> If you are using Angular 15+, you dont have `src/test.ts` use this [answer on stackoverflow to restore `src/test.ts`](https://stackoverflow.com/a/75323651/13112018).
Next add the ng-mock config to `src/test.ts`
```typescript
import { getTestBed } from '@angular/core/testing';
import {
BrowserDynamicTestingModule,
platformBrowserDynamicTesting,
} from '@angular/platform-browser-dynamic/testing';
import { MockInstance, MockService, ngMocks } from 'ng-mocks';
import { DefaultTitleStrategy, TitleStrategy } from '@angular/router';
import { CommonModule } from '@angular/common';
import { ApplicationModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
getTestBed().initTestEnvironment(
BrowserDynamicTestingModule,
platformBrowserDynamicTesting(),
{
errorOnUnknownElements: true,
errorOnUnknownProperties: true,
},
);
ngMocks.autoSpy('jasmine');
ngMocks.defaultMock(TitleStrategy, () => MockService(DefaultTitleStrategy));
ngMocks.globalKeep(ApplicationModule, true);
ngMocks.globalKeep(CommonModule, true);
ngMocks.globalKeep(BrowserModule, true);
jasmine.getEnv().addReporter({
specDone: MockInstance.restore,
specStarted: MockInstance.remember,
suiteDone: MockInstance.restore,
suiteStarted: MockInstance.remember,
});
```
We are going to change our test using two key utilities: `MockBuilder` and `MockRender`.
`MockBuilder` simplifies the setup of Angular testing modules by replacing dependencies, ensuring components under test are isolated for focused testing.
`MockRender` facilitates the instantiation and rendering of Angular components in unit tests, providing access to component instances and DOM elements to verify their behavior and interactions accurately.
Instead of using `TestBed`, I switch to MockBuilder, passing the component to test and the required module, in my case `HttpClientTestingModule`, and finally call `.mock` to specify which component I want to mock, `ProductList`.
> The .mock method supports an array like .mock(\[ProductsListComponent, AnotherComponent, ...\]);
The final code looks like:
```typescript
import { ProductsComponent } from './products.component';
import { ProductsListComponent } from '../components/products-list/products-list.component';
import { MockBuilder, MockRender, ngMocks } from 'ng-mocks';
import { HttpClientTestingModule } from '@angular/common/http/testing';
describe('ProductsComponent', () => {
beforeEach(() =>
MockBuilder(ProductsComponent)
.keep(HttpClientTestingModule)
.mock(ProductsListComponent),
);
it('should create', () => {
const fixture = MockRender(ProductsComponent);
expect(ngMocks.findInstance(ProductsComponent)).toBeTruthy();
});
});
```
Save and ta-da! We are ready with just a few lines of code and ready to start testing!
## Recap
We learned about how the testing Angular components becomes complex when dependencies like external libraries, child components are involved. Initially straightforward, but becomes hard when challenges with components relying on multiple dependencies, for example in the template.
When we use `NO_ERRORS_SCHEMA`, it initially masks issues. Creating stub components simplifies testing but adds maintenance overhead. In my opinion, I prefer `NgMocks` because it simplifies my work with utilities like `MockBuilder` and `MockRender` and minimal boilerplate.

👋 Hi, everyone! I’m Noor, and I’m excited to start my journey into the world of cloud computing and Amazon Web Services (AWS). In this post, I’ll provide an overview of what cloud computing is and how AWS plays a pivotal role in transforming the way businesses operate today.

## What is Cloud Computing?
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet ("the cloud"). This model allows users to access and manage resources on-demand without the need for physical infrastructure. Key benefits of cloud computing include:
- -**Scalability:** Easily scale resources up or down based on demand.
- - **Cost-Efficiency**: Pay only for what you use, reducing capital expenditures.
- - **Accessibility:** Access services and data from anywhere with an internet connection.

1,922,157 | Use Android Phone as advance router using OpenWrt | Introduction This project began with the idea of running OpenWrt with a 5G modem in the... | 0 | 2024-07-13T10:40:32 | https://dev.to/varunpalekar/use-android-phone-as-advance-router-using-openwrt-26hf | openwrt, android, virtualmachine, networking | # Introduction
This project began with the idea of running OpenWrt with a 5G modem in the most affordable way possible.
# Background
As a software engineer specializing in Platform Engineering, I sought an advanced router solution for home use. Previously I already had a intel NUC which I used to run OpenWRT router for home network.
# Power Consumption:
After observing a power consumption of approximately 14 watts during normal use, I decided to explore ARM alternatives.
# Research and Alternatives
I initially researched alternatives like the Raspberry Pi 4B and 5 models. I also considered using mobile operator internet, as I have a free 5G trial from my provider.
# Cost Considerations:
I found 5G modems for the Raspberry Pi to be too expensive, leading me to consider using android mobile to run OpenWrt.
# Project Steps
This led me to the idea of running OpenWrt on an Android phone to save the cost of a Raspberry Pi. Below are some options of running OpenWrt on Android
## 1. Directly run OpenWrt on Android
This is exceedingly difficult, as you need to rebuild openwrt for your phone and need to figure out all drivers and other things.
I have dropped this idea as need to spend lots of time figuring it out.
## 2. Running OpenWrt on Android OS as Docker container (or maybe lxc)
There are two main prerequisites:
1. A custom kernel build is required to enable features not available by default on Android. So, it is only possible for those phones which provide source code of their kernel or any third-party Android OS like lineageos if available for your phone. Detailed steps are already share by someone else in this post https://gist.github.com/FreddieOliveira/efe850df7ff3951cb62d74bd770dce27
2. Need to have root access, this is very easy if your already figure out above steps
For detailed instructions OpenWrt already maintained a guide given below.
Note: I tried the latest available version 23.05.3 is not working according to the given setup. Procd hangs with /sbin/init script, which can be due to multiple reasons, if someone interested can get into https://openwrt.org/docs/techref/init.detail.cc at step 2, it get hanged.
## 3. Running OpenWrt on Android OS in QEMU
### 3.1 QEMU with KVM
1. This process is currently complicated as KVM is not available on most phones. So, there are two options which I can get
Using official kvm which is only available for Google Pixel 6+ from android 13. So we don't know when it will be available for other
2. Build own android kernel with KVM support.
This is also prety much similar to Running OpenWrt on Android OS as Docker container, where need to build kernel with kvm module. I search the internet but didn't find single solution which works for large set of android models
### 3.2 QEMU without any hardware virtualization
Pre-requisite:
* Root phone
* termux installed
It is the easiest and most compatible way to run openwrt or any OS. The only problem is slow performance as compared to other solutions.
I will describe it in detail below how I tried it on Oneplus 9R Android Phone.
## 4. Running OpenWrt component directly in Android OS (in progress)
Initially I started to try to run using proot avaialble in termux but not able to run it. When I run /sbin/init it gets hanged, after looking to code looks like it hanged at Step 2 of https://openwrt.org/docs/techref/init.detail.cc as procd want to acquire pid 1 which is not possible (still my guess needs to look to code of it).
## 5. Running OpenWrt in Limbo EMU (in progress)
Running OpenWrt on Limbo EMU is faster in performance as compared to qemu in termux. I already tried Limbo x86 with OpenWrt x86 which is running smoothly with greater performance, but I am not able to use bridge and tap networking.
My android phone is root but Limbo EMU is not able to get root access for tap and bridging. If someone can get it working, please let me know, I am also curious.
# QEMU without any hardware virtualization
In this we will explain the process of running OpenWrt on android phone. I have tested the solution on OnePlus 9R (android 13) which is rooted, but we generally using general android adb command/features which are available in all phones, please let me know if you have any problems/questions.
## 1. Pre-requisite:
1.1 Rooted phone (su access)
1.2 termux installed
1.3 a system with adb connectivity with phone for shell access
## 2. Selection of networks
### 2.1. Internet Source (WAN)
We need to find the source of WAN which will be used to get the internet. It can be your mobile operator network or can also be WIFI or can also be from ethernet connected to your android Phone.
Phone just need to connect to internet via any means, it will automatically be used by OpenWrt, no extra configuration needed.
### 2.2. Internet sharing (LAN)
This is the network which others used to connect to your Phone. We can use android existing personal hotspot also for this.
To achieve this open Android hotspot setting in Android and set all setting required. Enable hotspot and disable it (why disable? we will enable it using cli later)
#### 2.1.1. Now open termux
#### 2.1.2. Check it required setting for hotspot by `cat /data/vendor/wifi/hostapd/hostapd_wlan1.conf`
#### 2.1.3. Turn on hotspot by CLI command `Note: If OS get restart, please do again`
```
pkg install iw -y
unset LD_PRELOAD
# Created a virtual managed interface for hotspot
sudo iw phy phy0 interface add wlan1 type managed
# Run hotspot. Don't connect your phone now as they will not able to get IP and internet
sudo /vendor/bin/hw/hostapd -dd -g /data/vendor/wifi/hostapd/global -B /data/vendor/wifi/hostapd/hostapd_wlan1.conf
```
Note: Some android phones are capable of provide hotspot and connect to other wifi network simultaneously. In this example I am using 5 ghz (Wifi 6 mode) for hotspot (For LAN) and 2.4 ghz to connect internet (For WAN). So please use your setting according to network technology needed for LAN and WAN.
### 2.3 Install Qemu
#### 2.3.1 Use adb to access termux from adb (optional)
As operating termux from mobile is not friendly as compared to from big screen computer, so below are some steps to run termux from computer.
* Open termux app on android
* Run following command to install ssh server
```
pkg update
pkg install openssh -y
# Set password for ssh
passwd
# run ssh server in background
sshd
```
* Now connect from laptop after having adb connect (connect android phone from system and enable usb debugging)
```
# Forward android
adb forward tcp:8022 tcp:8022
#ssh connect to android
ssh user@localhost -p 8022
```
Now you don't need to type commands in termux
#### 2.3.2 Install qemu and other required software/files
```
pkg install qemu-system-aarch64-headless qemu-utils wget curl tsu vim iw -y
mkdir openwrt
cd openwrt
# Download openwrt kernel
wget https://downloads.openwrt.org/releases/23.05.3/targets/armsr/armv8/openwrt-23.05.3-armsr-armv8-generic-kernel.bin -O openwrt-23-kernel
# Download openwrt root image
wget https://downloads.openwrt.org/releases/23.05.3/targets/armsr/armv8/openwrt-23.05.3-armsr-armv8-generic-squashfs-rootfs.img.gz -O openwrt-23-root.img.gz
gunzip -d openwrt-23-root.img.gz
# Convert and Resize root img
qemu-img convert -f raw -O qcow2 openwrt-23-root.img openwrt-23-root.qcow2
rm openwrt-23-root.img
qemu-img resize openwrt-23-root.qcow2 1G # replace 1G with your value
```
#### 2.3.3 Setup network bridge, so that OpenWrt access and manage personal android hotspot.
* Create a file `/data/data/com.termux/files/usr/etc/qemu/bridge.conf` with following entry
```
allow br0
```
* Create bridge network for sharing. `Note: If OS get restart, please do again`
```
sudo ip link add br0 type bridge
sudo ip link set dev wlan1 master br0
sudo ip link set dev br0 up
```
#### 2.3.4 Run Openwrt
* Qemu Start
```
sudo qemu-system-aarch64 -M virt -cpu cortex-a76 -accel tcg,thread=multi -m 256 -smp 4 -nographic -kernel openwrt-23-kernel -drive if=none,file=openwrt-23-root.qcow2,id=hd0 -device virtio-blk-device,drive=hd0 -append "root=/dev/vda" -device virtio-net,netdev=eth0,mac=92:e1:8f:69:43:b4 -netdev bridge,br=br0,id=eth0 -device virtio-net,netdev=eth1 -netdev user,id=eth1,net=192.0.2.0/24,dns=8.8.8.8
```
* Wait for system to boot (takes 2-5 min), when you see 8021q: adding VLAN 0 to HW filter on device eth1, then press enter
Check all networking is setup by ifconfig
```

Don't worry, I found an easier way. Follow these steps:
- Choose a theme.
I like the [Dante](https://github.com/JustGoodUI/dante-astro-theme) theme
- Rename the repository to {username}.github.io
As I did with [zwd321081.github.io](https://github.com/zwd321081/zwd321081.github.io).This is crucial because Github pages has specific naming rules
- Go to the Actions tab and search for the Astro workflow
- Making some modification to `astro.yml`
Remove the `--site` and `--base` options. This will result in your default URL being structured as `https://{username}.github.io/{reponame}`.
By removing these options, you eliminate the subpage path.
- Visit your page at the domain https://{username}.github.io, such as [mine](https://zwd321081.github.io/).

**Introduction: Why Version Control and Deployment are Critical to Web Development**
Within the fast-moving environment of web development, efficient change management, team collaboration, and hassle-free deployment of developed applications to production environments are critical in ensuring that websites and web applications are of high quality and reliable. At the very center of this process lies Git, a very powerful distributed version control system that has revolutionized the way changes in code are tracked, managed, and shared between developers.
Whether you're an experienced web developer or just starting out, learning Git and the best deployment practices could increase your efficiency many times over by putting your development workflow on track and helping you deliver projects effectively. In view of these realities, this guide will cover the basics of Git, its main features and commands, and how to make use of them in combination with deployment strategies for creating a full and efficient web development process.
**Basic Understanding of Git**
One needs to understand the core ideas and concepts which would make Git into the power pack for version control. It's based on a distributed model, meaning that every developer gets a local copy of the work area source code and the entire history. This allows working offline with no hassle, and enables collaboration.
For the most part, any web design class would have laid the foundation by introducing version control systems, so by now you must have a clear understanding of the basic ideas and principles on which Git is founded. Mastering these basics will let you move around easily in the Git ecosystem, understand how Git works, and harness its power for your web development projects.
**Installing and Setting Up Git on Your System**
First, you need to install Git on your computer or server in order for it to be put to use. Again, installation—well, is different depending on the operating system; detailed guides and resources on how to do so are openly shared on the Git website. After installation, you would be required to set up environments, such as configuring user information, SSH keys, aliases, and other configurations to give ease to your workflow.
Most web development courses include practical exercises performed during the course and tutorials on how to install and configure Git, so that students set up their development environment and start using Git effectively right from the very beginning.
**Create and Manage Git Repositories**
There's a reason the repositories are at the center of any Git-based workflow. They're the greatest storage locations for your project code and all its history. In this section, you will learn about the creation of new repositories and cloning of existing ones, and how to manage their structure and contents properly by using appropriate Git commands. You'll also be able to explore the concept of a remote repository, which enables collaboration and sharing among team members working on their code.
In most cases, a web design course will cover the basics of repository management using Git to help students learn how to create, maintain, and collaborate on projects based on Git.
**Mastering Git Commands to Conduct Version Control**
Git provides a large set of commands for accomplishing a number of version control tasks, from simple change tracking and conflict resolution. In this section, you will look at essential Git commands like `add`, `commit`, `push`, `pull`, and `status`, and how to use them efficiently in your everyday workflow for web development. You will also study higher-level commands like `rebase`, `cherry-pick`, and `reset`, which will help you go through complex situations and always keep a clean and tidy commit history.
It is common for a Web Design Course to spend a considerable amount of time teaching Git commands so that students can have a very strong grasp of this most essential skill for version controlling and collaboration.
**Collaboration with Git: Branching, Merging, and Pull Requests**
Among the many strongest features of Git is its support for branching, which allows developers to work on separate lines of development concurrently without interfering with the main line of code. In this section, you will learn how to create and switch between branches, manage those branches with Git commands, merge changes back into the main branch, and how all of that comes together in performing a pull request. You will also learn best practices for naming of branches, strategies in merging, and in resolving conflicts so collaboration between team members happens smoothly.
Most of the [web design courses](https://bostoninstituteofanalytics.org/full-stack-web-development/) will often cover the principles and techniques for collaborative development using Git. This provides skills and knowledge in how to collaborate best in teams and contribute to common projects.
**The Role of Web Design Course in Enhancing Git and Deployment Skills**
This Web Design Course will be most useful to people who want to develop their Git and deployment skills. They provide a comprehensive curriculum covering the theoretical foundation, practical applications, and nuances of the industry in terms of version control and deployment, thereby enabling the learner, as much as possible, to effectively become a web developer.
The Web Design Course has constructed a learning environment rich in lectures, practical exercises, and real-case studies that allow a student to understand Git deeply and the roles it has played in modern web development workflows. With exposure to cutting-edge research, industry insight, and expert mentorship, students learn to confidently and effectively make use of Git and best practices of deployment as valuable and very strong tools for their web development projects.
**Integrating Git with Development Environments and IDEs**
Even more fundamental to your Git-based workflow will be the ability to use it inside your favorite development environment or IDE. Most well-known IDEs nowadays come with built-in support for Git, and between the most popular, one finds Visual Studio Code, IntelliJ IDEA, and WebStorm. This section teaches you how to set up and get started with these Git integrations, solving a lot of extra functionality by drawing plugins and extensions to drive productivity and efficiency.
Web Design Course often covers the integration of Git within different development environments, making it possible for students to collaborate in unison with Git from their favorite coding tools.
**Deploying Web Applications: From Local to Live**
Now, once you have developed and tested your web application using Git for version control, you would want to deploy it onto a live server or hosting environment. In the next section, you'll be introduced to some of the deployment strategies, which include manual FTP/SFTP uploads and server-side Git repositories, before exploring deployment platforms such as Netlify and Vercel. You will also work on setting up your hosting environment to accommodate your Git-based workflow so that deployment goes smoothly.
Many Web Design Courses include modules on best practices for deployment. It therefore enables learners to smoothly move their web applications from development into production through Git and other means of deployment.
**Automating the Deployment Process with CI and CD**
To ensure error-free deployment procedures with minimal scope for errors due to manual intervention, many teams have adopted the concepts of Continuous Integration and Continuous Deployment. In this section, you will learn to set up a Continuous Integration and Continuous Deployment pipeline using GitHub Actions, Travis CI, or CircleCI. It builds, tests, and subsequently deploys your application any time changes are pushed to the Git repository. Embracing continuous integration and continuous deployment means that your web applications are always up to date and execute the newest version of your codebase.
Most web development courses will include knowledge on concepts and good practices on CI/CD. Students will be able to create automated deployment workflows for easily delivering updates.
**Troubleshooting and Resolving Git and Deployment Issues**
However careful you may be in planning and executing your Git-based workflow, it is sure to be marred by issues or errors at times that demand troubleshooting and resolution. You'll learn how to identify and diagnose common Git and deployment problems using merge conflicts, push rejections, and failed deployments. Then, there are ways to resolve the issues: through Git commands such as revert, reset, and cherry-pick, and by engaging fellow team members in resolving thorny problems using effective communication and collaboration.
Web design courses therefore range from case studies to exercises in troubleshooting, targeting the development of problem-solving skills in students for sailing smoothly through nasty situations and maintaining the stable reliability of the web development process.
**Conclusion: Embracing Git and Deployment as Essential Web Development Skills**
With the constantly changing landscape of web development, one of the most critical skills any aspiring web developer is likely to possess must be the ability to use Git properly for version control and deployment. This course shall put you in a very good position to deal with the complexities of modern web development and to deliver high-quality, reliable web applications by mastering the very foundations of Git: from installation and configuration to advanced commands for collaborative workflows.
On the other hand, Web Design Course will help to sharpen Git and deploy skill-sets by giving detailed curricula going directly into technical and strategic considerations for version control and deployments. Much knowledge from these specialized programs verses in you the power of Git shall have you well on your way toward driving innovation, productivity, and value that abounds in the fast-paced web development space. | jinesh_vora_ab4d7886e6a8d |

It is the way we... | 0 | 2024-07-13T11:03:36 | https://dev.to/kemiowoyele1/coloring-your-web-world-a-guide-to-css-colors-4b2a | Color is a form of electromagnetic radiation that is visible to the human eye. It is the way we perceive and experience different wavelengths of light. Colors can evoke emotions, convey meanings, and add depth and complexity to our experiences.
Color plays a significant role in many aspects of our day-to-day life. It helps to convey messages, express identity, influence mood, stimulate appetite, influence fashion trends, enhance artistic expression, etc.
For web developers, colors help to enhance user experiences, affect legibility, create appealing effects and aesthetics, indicate interactive elements, and evoke emotions. Web developers and designers must be very careful in choosing colors for their projects as it significantly affects how users interact with the page. Other reasons why developers must pay attention include;
1. Accessibility: some users may have visual impairment or color blindness. The colors should be used in such a way that there is enough contrast between the background and text. Also, different modes like light and dark modes or different color themes could be made available for the sake of users with color sensitivity.
2. Brand identity: colors are usually used to represent brand identity. When building for an organization, it is important to reflect the colors of the organization’s brand for consistency, and for reinforcing the brand's identity and recognition.
3. Also, take note of the cultural implications of colors and how to use colors to evoke the desired emotions.
4. Colors can also determine if the website/app will be visually appealing or repulsive to the users. It is important to ensure that beauty and aesthetics are taken into consideration.
5. Colors can also be used to direct the users on how to interact with the websites. Call-to-action buttons are usually made to stand out. Also, color red is usually used to warn users against deleting important data.
## how to indicate colors in CSS
There are several color systems available in CSS. However, in this course, we shall discuss;
• Color keywords
• Hex color
• Hexa colors
• Rgb()
• Rgba()
• Hsl()
• Hsla()
## Color keywords
One way of representing colors in CSS is obviously by their known names. Names like red, purple, green, blue, etc. are easily identifiable. There are also variations of those colors, like darkblue, cornflowerblue, darkgreen, darkorange, darkcyan, slateblue, slategrey, seagreen, hotpink etc.
Besides the fact that not all colors and shades have names, it is also a lot of work to memorize the colors by their various names. You may also know the name of the color you intend to use, but that name may not be a valid CSS color keyword or may look slightly different in CSS from what you know the color to look like.
Besides that, color keywords are only available for just 147 colors. Whereas, the human eye is said to see and distinguish approximately between 1 million to 1.5 million colors. And arguments are disputing this figure with claims that the eyes can see way more than that.
Also, the color keywords do not have alpha support, thereby making it difficult to add transparency to the colors.
In other to limit some of these challenges, CSS allows us to create colors, or mix colors with a couple of color systems. Some of them require mixing colors; others involve manipulating the lightness, transparency, and saturation of existing colors and hues.
## Hexadecimal (hex) colors
The hexadecimal color system allows for a lot more flexibility with creating colors, and gives a lot more options to the designers/developers with colors to choose from. With the hex system, colors are created by mixing red, blue, and green.
The hexadecimal system starts with the # symbol and then followed by six digits. These digits range from 0-f. So, rather than have the numbers like
0 1 2 3 4 5 6 7 8 9,
as in decimal numbers, making up ten,
We have numbers
0 1 2 3 4 5 6 7 8 9 a b c d e f
Making up 16.
So to combine a hex color, you’ll have;
In decimal notation, each of these values corresponds to an integer between 00 and FF, or 0 and 255. The hexadecimal notation allows for the representation of 256 ^ 3 or 16,777,216 colors in total. Black represents the absence of all three colors; while white represents the full capacity of all three colors. To get various shades of grey, have all three colors in equal proportions.
You can also have as many shades of the same colors as you can imagine. A couple of blue shades for example.
We can make thousands of shades from blue alone, by ensuring that the value for blue is higher than that of red and green. You can also do the same with red and green. In most cases, a color picker will help with choosing colors.
**Applying transparency**
You can apply transparency to hexadecimal by adding an extra alpha value to the hex color. The closer the number is to zero, the higher the transparency while a higher number will be more opaque. For example,
(#000d or #fefe56dd will add a little transparency to the colors, and a color of say #0004 0r #fefe5644 will be much more transparent.)
## Rgb() colors
rgb() colors are quite similar to the hexadecimal color system. They both represent a mixture of red, blue, and green with 255 possible values for each color. The difference here however is the syntax. The rgb() colors use decimal numbers of 0-255, separated by comma to represent each color.
Syntax;
rgb(red, green, blue);
## Rgba()
Rgba() gives the opportunity to add opacity/transparency to the colors. The extra a there is called the alpha value and is a number between 0 and 1. The closer the number is to zero, the more transparent the color will be.
## Hsl() colors
Hsl stand for
Hue: specifies the color. Represented by the degree along the color wheel. 0° is red,
Saturation: indicating the level of vividness of the color. 0 will give a gray color, whereas 100% will give the most vivid version of the color.
Lightness: in percentage indicating how light or dark the color would be;
**Illustration**
The image below illustrates the HSL hue. The saturation has been set to 100%, and lightness 50% for all cases.
2.
Now let’s take a hue of 0deg, and 50% lightness and see how different saturations look like
Now, let’s maintain the hue of 0deg, and saturation of 100% and see how the lightness plays out.
## Conclusion
This text provides a comprehensive overview of colors in web development, including their importance, cultural implications, and how to represent them in CSS using various color systems.
Here is a summary of the color systems mentioned:
• Color Keywords: 147 predefined color names, e.g. "red", "blue", and "green".
• Hexadecimal (Hex): Six-digit code starting with #, e.g. #FF0000 for red.
• RGB: Decimal values for red, green, and blue, e.g. rgb(255, 0, 0) for red.
• RGBA: Adds alpha value for transparency, e.g. rgba(255, 0, 0, 0.5) for semi-transparent red.
• HSL: Hue, saturation, and lightness values, e.g. hsl(0, 100%, 50%) for red.
• HSLA: Adds alpha value for transparency, e.g. hsla(0, 100%, 50%, 0.5) for semi-transparent red.
The text also provides examples and illustrations to help understand how to work with colors in CSS.

1,922,172 | JavaScript ES6+ Features: A Complete Overview | Introduction JavaScript is constantly evolving, and keeping up with the latest features is... | 0 | 2024-07-13T11:25:17 | https://dev.to/mukeshb/javascript-es6-features-a-complete-overview-15a7 | javascript, webdev, tutorial, beginners | ## Introduction
JavaScript is constantly evolving, and keeping up with the latest features is crucial for modern web development. Since ES6, JavaScript has introduced new features that make coding more efficient.
Understanding and utilizing the latest JavaScript features can greatly enhance your productivity and code quality, making your applications more robust and maintainable.
In this blog, will provide overview of the key features introduced in ES6 and beyond, including let and const, arrow functions and more.
Key Features Introduced in ES6+
## 1. let and const
JavaScript introduced two new ways to declare variables let and const. These provide better scoping and more control over how variables are used in your code compared to the traditional var.
### let
let is used to declare variables that can be reassigned. Unlike var, let has block scope, meaning it is only accessible within the block (curly braces {}) where it is defined.
### Example
``` js
if (true) {
let x = 10;
console.log(x); // Output: 10
}
console.log(x); // Error: x is not defined
```
- The `if` statement checks if the condition `true` is met (which it always is in this case).
- When the condition is true, the code block `{ ... }` executes.
- `let x = 10;` declares a variable `x` with block scope (scoped to the nearest curly braces `{ ... }`).
- `x` is assigned the value `10`.
- `console.log(x);` outputs the value of `x`, which is `10`, to the console.
- The output displayed is `10`.
- `console.log(x);` attempts to output the value of `x` to the console.
- However, `x` is not accessible outside the block where it was defined (`if` block).
- JavaScript throws an error: `ReferenceError: x is not defined`.
- This error occurs because `let` variables are block-scoped and exist only within the block (curly braces) where they are defined.
### const
const is used to declare variables that should not be reassigned. Like let, const has block scope. Once a variable is assigned a value using const, it cannot be changed.
``` js
const y = 20;
console.log(y); // Output: 20
y = 30; // Error: Assignment to constant variable.
```
- `const` declares a constant variable named `y`.
- Constants (`const`) are variables that cannot be reassigned once their value is set.
- `y` is initialized with the value `20`.
- `console.log(y);` outputs the value of `y`, which is `20`, to the console.
- The output displayed is `20`.
- Attempts to reassign the value of `y` to `30`.
- However, constants (`const`) in JavaScript cannot be reassigned after their initial assignment.
- JavaScript throws an error: `TypeError: Assignment to constant variable.`
- This error occurs because `y` is declared as a constant (`const`), and you cannot change its value once it's set.
## 2. Arrow Functions
Description:
Arrow functions provide a concise syntax for writing function expressions. They do not have their own this context, making them particularly useful for callbacks.
### Example
``` js
// Traditional function expression
var add = function(a, b) {
return a + b;
};
// Arrow function expression
const add = (a, b) => a + b;
```
- `var add` declares a variable named `add`. This variable will store a function.
- The `function(a, b)` part creates an anonymous function (a function without a name) that takes two parameters, `a` and `b`.
- Inside the curly braces {}, the function body contains a single statement: `return a + b;`. This means the function will add the two parameters `a` and `b` and return the result.
- The function is assigned to the variable `add`. Now, `add` can be used to call the function and perform the addition.
- When `add(2, 3)` is called, the function adds `2` and `3` and returns `5`.
- `const add` declares a constant variable named `add`. This means the variable `add` cannot be reassigned to a different value or function.
- The `(a, b) => a + b` part is an arrow function. It is a shorter and more concise way to write a function.
- `(a, b)` lists the parameters of the function, just like in the traditional function expression.
- The `a + b` part is the body of the function. Since there are no curly braces `{}`, this function has an implicit return, meaning it automatically returns the result of `a + b`.
- When `add(2, 3)` is called, the arrow function adds `2` and `3` and returns `5`.
## 3. Template Literals
Template literals let us create strings that can span multiple lines and include variables easily. Use template literals for embedding variables and expressions in strings.
### Example:
``` js
const name = 'John';
const greeting = `Hello, ${name}!`;
console.log(greeting); // Hello, John!
```
- `const` declares a constant variable named `name`.
- `'John'` is assigned as the value of `name`.
- Constants `const` are variables that cannot be reassigned once their value is set.
- Template literals (enclosed in backticks) allow embedding expressions inside strings.
- `${name}` within `${}` is an expression that gets replaced with the value of the `name` variable.
- `${name}` evaluates to `'John'`, so `greeting` becomes `'Hello, John!'`.
- `console.log()` outputs the value of `greeting` to the console.
- The output displayed in the console is `Hello, John!`.
## 4. Destructuring Assignment
Destructuring allows you to unpack values from arrays or properties from objects into distinct variables. Use destructuring to simplify the extraction of values from arrays and objects.
### Example:
``` js
const user = { name: 'John', age: 30 };
const { name, age } = user;
console.log(name); // John
console.log(age); // 30
```
- `const` declares a constant variable named `user`.
- `user` is an object with two properties: `name` with value `'John'` and `age` with value `30`.
- Object destructuring allows you to extract specific properties from an object into variables with the same names.
- `{ name, age }` on the left-hand side of `=` declares two new variables (`name` and `age`).
- These variables are assigned the values of `user.name` and `user.age`, respectively.
- `console.log(name);` outputs the value of the variable `name` to the console.
- The output displayed in the console is `John`.
- `console.log(age);` outputs the value of the variable `age` to the console.
- The output displayed in the console is `30`.
## 5. Default Parameters
Default parameters allow you to set default values for function parameters if no value or undefined is passed. Use default parameters to ensure functions have default values.
### Example:
``` js
function greet(name = 'Guest') {
console.log(`Hello, ${name}!`);
}
greet(); // Hello, Guest!
```
- `function greet(...)` declares a function named `greet`.
- `name = 'Guest'` is a parameter with a default value of `'Guest'`. This means if no argument is passed to `greet()`, `name` will default to `'Guest'`.
- Template literals (enclosed in backticks `` ` ``) allow embedding expressions inside strings.
- `${name}` within `${}` is an expression that gets replaced with the value of the `name` parameter passed to the function.
- If no `name` parameter is provided, it defaults to `'Guest'`.
- `greet()` calls the `greet` function without passing any arguments.
- Since no argument is passed, `name` defaults to `'Guest'`.
- The function then logs `'Hello, Guest!'` to the console.
## 6. Rest and Spread Operators
The rest operator (...) allows you to represent an indefinite number of arguments as an array. The spread operator (...) allows an iterable to be expanded in places where zero or more arguments or elements are expected. Use rest operator in function parameters to handle various arguments. Use spread operator to expand arrays and objects.
### Example:
``` js
function sum(...numbers) {
return numbers.reduce((a, b) => a + b, 0);
}
console.log(sum(1, 2, 3)); // 6
const arr1 = [1, 2];
const arr2 = [...arr1, 3, 4];
console.log(arr2); // [1, 2, 3, 4]
```
- `function sum(...numbers)` declares a function named `sum` that uses a rest parameter `...numbers`.
- The rest parameter `...numbers` allows the function to accept any number of arguments and gathers them into an array named `numbers`.
- `numbers.reduce(...)` applies the `reduce` method on the `numbers` array.
- The `reduce` method iterates over each element in the `numbers` array and accumulates a single value (`a + b`).
- `(a, b) => a + b` is an arrow function that adds two numbers `a` and `b`.
- `0` is the initial value of `a` in the reduction process.
- `sum(1, 2, 3)` calls the `sum` function with three arguments: `1`, `2`, and `3`.
- The function calculates the sum of these numbers (`1 + 2 + 3`) using `reduce`.
- The result `6` is logged to the console.
- `const arr1` declares a constant variable `arr1` initialized with an array `[1, 2]`.
- `...arr1` spreads the elements of `arr1` into the new array `arr2`.
- `[...arr1, 3, 4]` creates a new array `arr2` by combining the elements of `arr1` (`1` and `2`) with `3` and `4`.
- `console.log(arr2)` outputs the contents of `arr2` to the console.
- The output displayed is `[1, 2, 3, 4]`, which is the combined array with elements from `arr1` and additional elements `3` and `4`.
## 7. Classes
Classes provide a more intuitive and simpler syntax for creating objects and dealing with inheritance in JavaScript. Use classes to create objects and establish inheritance hierarchies.
### Example:
``` js
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
greet() {
console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`);
}
}
const john = new Person('John', 30);
john.greet(); // Hello, my name is John and I am 30 years old.
```
- `class Person` declares a new class named `Person`.
- Classes in JavaScript provide a way to define blueprints for creating objects with shared methods and properties.
- The `constructor` method is a special method for creating and initializing objects created with a class.
- `constructor(name, age)` defines parameters `name` and `age`.
- `this.name = name;` assigns the value of `name` passed to the constructor to the `name` property of the object being created (`this` refers to the current instance of the `Person` class).
- `this.age = age;` assigns the value of `age` passed to the constructor to the `age` property of the object being created.
- `greet()` defines a method `greet` within the `Person` class.
- Methods in classes are functions that can be called on instances of the class.
- Template literals (enclosed in backticks `` ` ``) allow embedding expressions inside strings.
- `${this.name}` and `${this.age}` are expressions that are replaced with the values of `name` and `age` properties of the current object (`this` refers to the current instance of `Person`).
- `new Person('John', 30)` creates a new instance of the `Person` class.
- The `constructor` method is automatically called with arguments `'John'` and `30`, initializing the `name` and `age` properties of the `john` object.
- `john.greet()` calls the `greet` method on the `john` object.
- The method logs `"Hello, my name is John and I am 30 years old."` to the console, using the values stored in `john.name` and `john.age`.
## 8. Promises
Promises provide a way to handle asynchronous operations more gracefully than callbacks. Use promises for handling asynchronous operations such as API calls.
### Example:
``` js
const fetchData = () => {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve('Data fetched');
}, 1000);
});
};
fetchData().then(data => {
console.log(data); // Data fetched
});
```
- `const fetchData` declares a constant variable `fetchData` initialized with an arrow function `() => { ... }`.
- Arrow functions provide a concise way to write functions in JavaScript.
- `new Promise(...)` creates a new `Promise` object.
- The `Promise` constructor takes a function with `resolve` and `reject` parameters.
- Inside this function:
- `setTimeout(..., 1000)` schedules a function to be executed after a delay of 1000 milliseconds (1 second).
- The arrow function `() => { resolve('Data fetched'); }` is executed after the timeout.
- `resolve('Data fetched')` fulfills the promise with the value `'Data fetched'`.
- `fetchData()` calls the `fetchData` function, which returns a `Promise`.
- `.then(data => { ... })` attaches a callback function to handle the resolved value (`data`) when the promise is fulfilled.
- The arrow function `data => { console.log(data); }` is executed once the promise is resolved successfully (`resolve('Data fetched')`).
- `console.log(data)` outputs the value of `data` ('Data fetched') to the console.
## 9. Async/Await
Async/await allows you to write asynchronous code in a more synchronous and readable manner.Use async/await for clearer and more readable asynchronous code.
### Example:
``` js
const fetchData = () => {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve('Data fetched');
}, 1000);
});
};
async function getData() {
const data = await fetchData();
console.log(data); // Data fetched
}
getData();
```
- `const fetchData` declares a constant variable `fetchData` initialized with an arrow function `() => { ... }`.
- Arrow functions provide a concise way to define functions in JavaScript.
- `new Promise(...)` creates a new `Promise` object.
- The promise executor function takes two parameters: `resolve` and `reject`.
- Inside the executor function:
- `setTimeout(..., 1000)` schedules a function to be executed after a delay of 1000 milliseconds (1 second).
- The arrow function `() => { resolve('Data fetched'); }` is executed after the timeout completes.
- `resolve('Data fetched')` fulfills the promise with the value `'Data fetched'`.
- `async function getData()` declares an asynchronous function named `getData`.
- Async functions allow you to write asynchronous code in a synchronous-like manner, making it easier to work with promises and other asynchronous operations.
- `await fetchData()` pauses the execution of `getData` until the promise returned by `fetchData` settles (fulfills or rejects).
- Once fulfilled, `await` returns the resolved value (`'Data fetched'`) and assigns it to the variable `data`.
- `console.log(data);` outputs the value of `data` ('Data fetched') to the console.
- `getData()` calls the `getData` function, initiating the execution of asynchronous operations defined inside `getData`.
## Conclusion
ES6+ features provide powerful tools for writing modern JavaScript. By understanding and using these features, developers can write more efficient, readable, and maintainable code.

Sometimes, things are what they are simply because nobody knows how... | 9,995 | 2024-07-13T13:14:21 | https://dev.to/spo0q/php-no-its-not-possible-4ji6 | php, beginners, programming | You may add "yet" to this title! Sometimes, things are what they are simply because nobody knows how to do better.
However, it does not mean everything is a good idea.
## PHP doesn't support multiple inheritance
You simply cannot do the following:
```PHP
class Child extends Parent1, Parent2 {}
```
However, many developers would think there are better approaches, like using interfaces to force classes to implement specific behaviors.
Note that you may still apply some kinda of multiple inheritance to those interfaces (if that really makes sense in your case):
```PHP
interface A {}
interface B {}
interface C extends A, B {}
```
However, that's not the best argument against multiple inheritance, to me. Many programming languages focus on simplicity and readability over complexity.
Introducing multiple inheritance could lead to lots of misuses, not to mention the Diamonds problem, which would be problematic for high-level languages such as PHP.
It's best if you can avoid **unnecessary** complexity.
## PHP does not support multi-threading
Many programming languages provide built-in tools to execute multiple threads _at the same time_ (e.g., Java, C++).
Pthreads tried to introduce multi-threading in PHP but Joe Watkins the creator of pthreads and parallel announced in February 2019 that:
> pthreads will no longer be maintained after PHP 7.4 due to architectural flaws.
[Source: PHP documentation - phtreads](https://www.php.net/manual/en/book.pthreads.php)
If you want to dig further, you may check [parallel](https://www.php.net/manual/en/philosophy.parallel.php), which is inspired by Go concurrency.
While parallel is pretty cool, do you really need such complexity in your case?
If you need a built-in mechanism for asynchronous processing, it is now possible with [Fibers](https://www.php.net/manual/en/language.fibers.php) (since PHP 8.1).
Fibers allow you to write interruptible functions.
While Fibers are pretty cool, do you really need such complexity in your case?
Using third-party solutions such as ReactPHP or Swoole could be a better choice, especially if you only need an event loop.
Better than that, you may build a queue mechanism that can handle messages and retry failed jobs.
The Symfony component [HTTP Client](https://symfony.com/doc/current/http_client.html) also supports various asynchronous operations (e.g., concurrent asynchronous streamed and multiplexed requests/responses).
## PHP is not meant for real-time processing
PHP is an interpreted language, which is incompatible with intensive operations and systems that require low latency and high predictability.
While is true, why would you use PHP for High-Frequency Trading, streaming, online gaming or high-level supervision of machines and processes?
## Wrap up
PHP is meant for the web and many other creative uses you may know.
I hope it will keep its simplicity, as it is definitely a feature. | spo0q |
1,922,174 | Checking Efx - testable effects for Elixir | Mocking in Elixir is always a hot topic, mainly because of people coming from different other... | 0 | 2024-07-13T11:32:17 | https://katafrakt.me/2024/07/02/checking-efx/ | elixir, testing, functional | Mocking in Elixir is always a hot topic, mainly because of people coming from different other technologies having different expectation. The most "cannonical" solution, [Mox](https://hexdocs.pm/mox/Mox.html), gives a lot of security with regard to what the fake implementation returns, but requires a bit of a ceremony from the programmer. Other solutions like [Mock](https://github.com/jjh42/mock), [Rewire](https://github.com/stephanos/rewire) or [Bypass](https://hexdocs.pm/bypass/Bypass.html) offer more ad-hoc mocking, but t the price of the tests heving to be synchronous. Then there's [Mimic](https://github.com/edgurgel/mimic), which offers ad-hoc mocking and supports async
tests.
In this busy area, a new library appeared very recently. It's called [Efx](https://github.com/bravobike/efx) and its description does not even mention mocking:
> A library to declaratively write testable effects
It immediately cought m attention, because it seems to implement what I described as "[purity injection](/2022/10/19/purity-injection-elixir/)" some time ago. As a programmer, you write a default impure implementation of the code, but you mark it as an "effect". Then in tests you replace a stateful implementation with something more predictable (you "inject purity") and you can enjoy nice, stable and
fast tests.
This post is a result of taking the library on a quick testing round. I decided to use it to the exact same problem as in the "purity injection" post. To remind, when you create a new order in your e-commerce application, you need to assign it a number. The number needs to be unique within a tenant and it should not contain ambiguous characters. The naive implementation, with which we started, looked like this:
```elixir
defmodule OrderNumber do
def generate(tenant_id) do
candidate =
:crypto.strong_rand_bytes(4)
|> Base.encode32(padding: false)
|> replace_ambiguous_characters()
query =
from o in Order,
where: o.tenant_id == ^tenant_id and o.order_id == ^candidate
if Repo.exists?(query), do: generate(tenant_id), else: candidate
end
end
```
Now, let's change this code to support effects in Efx's terminology. We will have two: one for generating a random string and another to check if the sequence has already been used.
```elixir
defmodule Commerce.OrderNumber do
use Efx
def generate(tenant_id) do
candidate =
generate_random()
|> replace_ambiguous_characters()
case check_existence(candidate, tenant_id) do
true -> generate(tenant_id)
false -> candidate
end
end
@spec generate_random :: String.t()
defeffect generate_random() do
:crypto.strong_rand_bytes(4)
|> Base.encode32(padding: false)
end
@spec check_existence(String.t(), integer()) :: boolean()
defeffect check_existence(candidate, tenant_id) do
import Ecto.Query
from(o in Commerce.Order,
where: o.tenant_id == ^tenant_id and o.number == ^candidate)
|> Commerce.Repo.exists?()
end
defp replace_ambiguous_characters(string) do
string
|> String.replace("I", "1")
|> String.replace("O", "0")
end
end
```
Both `generate_random/0` and `check_existence/2` effects are compiled to a regular functions, which are called inside `generate/1`. There's nothing too fancy in it, so let's see about testing it. In the first test we want to check if the ambiguous characters are replace, so we want our RNG to generate a sequence with such characters:
```elixir
defmodule Commerce.OrderNumberTest do
use Commerce.DataCase, async: true
use EfxCase
alias Commerce.OrderNumber
test "replace Os and Is" do
bind(OrderNumber, :generate_random, fn -> "A5O0I1" end)
bind(OrderNumber, :check_existence, fn _, _ -> false end)
assert OrderNumber.generate(1) == "A50011"
end
end
```
The `bind/3` function replaces the implementation of effects from a default one to a fake one. Now our `generate_random/0` function returns `A5O0I1` strings, which then replaces the ambiguous characters. We also need to `bind` the implementation of `check_existence` here, even though we actually know that the database is empty so the check would pass. There are two reasons to do so:
1. We **want** to do it - isolate all side-effects in tests, so tests are faster and less reliant on the infrastructure
2. We **have** to do it - because Efx forces us to
If we don't `bind` the `check_existence`, we would get an error:
```
** (RuntimeError) Mock for function check_existence/2 missing
(efx 0.1.11) lib/efx_case/mock.ex:95: EfxCase.Mock.get_fun/3
(efx 0.1.11) lib/efx_case/mock_state.ex:66: anonymous fn/5 in EfxCase.MockState.call/4

Last message (from #PID<0.405.0>): {:get_and_update, #Function<1.67167648/1 in EfxCase.MockState.call/4>}
```
After this is done, we can test more elaborate cases:
```elixir
test "use first candidate when existence check is false" do
bind(OrderNumber, :generate_random, fn -> "ABC" end)
bind(OrderNumber, :generate_random, fn -> "123" end)
bind(OrderNumber, :check_existence, fn _, _ -> false end)
assert OrderNumber.generate(1) == "ABC"
end
test "use second candidate when first existence check is true" do
bind(OrderNumber, :generate_random, fn -> "ABC" end, calls: 1)
bind(OrderNumber, :check_existence, fn _, _ -> true end, calls: 1)
bind(OrderNumber, :generate_random, fn -> "123" end)
bind(OrderNumber, :check_existence, fn _, _ -> false end)
assert OrderNumber.generate(1) == "123"
end
```
Here we `bind` the effects few times. The second test shows `calls: 1` option passed, which makes sure that `bind` only binds once. After that, the next bound implementation is used.
Finally, just to be sure, we may want to write a test actually calling the database:
```elixir
test "check against actual database" do
bind(OrderNumber, :generate_random, fn -> "ABC" end, calls: 1)
bind(OrderNumber, :check_existence, {:default, 2})
bind(OrderNumber, :generate_random, fn -> "123" end)
%Commerce.Order{tenant_id: 1, number: "ABC"}
|> Commerce.Repo.insert!()
assert OrderNumber.generate(1) == "123"
end
```
Binding with `{:default, arity}` lets us call the original implementation. This has to be done fully intentionally, not cutting corners.
We have successfully tested our order number generator in a much cleaner way, compared to my original post, without passing dependencies as an argument. Overall I think this is a very promising approach that, aside for improving using fake implementation in tests, nudges the developer in a nice way to:
* Think about side-effects when writing the code - you need to wrap them in `defeffect`
* Keep the number of impure functions in the module as low as possible - you have to always bind them all
* Use `@spec`s - `defeffect` requires them; although there are no type checks whether a fake implementation adheres
to the spec, at least having to define it might help to visually identify problems.
I think Efx is a great addition to Elixir ecosystem and I salute the author. Nice job! | katafrakt |
1,922,175 | The Impact of AI on Junior-Level Jobs | The rapid advancement of artificial intelligence (AI) is transforming industries at an unprecedented... | 0 | 2024-07-13T11:33:44 | https://dev.to/elukuro/the-impact-of-ai-on-junior-level-jobs-2ocg | programming, beginners, ai, productivity | The rapid advancement of artificial intelligence (AI) is transforming industries at an unprecedented rate, bringing both opportunities and challenges. Among the most affected by this technological revolution are junior-level professionals. From copywriting and UX writing to programming and administrative tasks, AI is increasingly capable of performing tasks traditionally carried out by entry-level workers. This shift poses significant questions about the future of work and the steps we need to take to adapt.
#### The Threat to Entry-Level Jobs
AI's capabilities have grown to include a wide array of functions that were once the domain of human workers. For instance, AI-driven tools are now proficient in generating content for blogs, marketing materials, and even technical documents. Applications like OpenAI's GPT-4 can produce coherent, contextually relevant text with minimal human input. This advancement threatens the job security of junior copywriters and UX writers, who typically start their careers performing these exact tasks.
Similarly, administrative roles such as drafting contracts, taking notes, and creating resumes are also at risk. AI-powered platforms can automate these processes, delivering accurate and efficient results. For example, AI can quickly draft a contract by analyzing templates and previous documents, saving time and reducing the need for a human touch.
Junior programmers are not immune to this trend either. Code generation tools like GitHub Copilot can assist in writing code, debugging, and even suggesting improvements. These tools, while beneficial for seasoned developers, could make it challenging for newcomers to find entry-level positions, as their tasks become increasingly automated.
#### Navigating the New Landscape
Given these challenges, it's crucial for junior-level professionals and those entering the job market to develop strategies to remain relevant. Here are a few recommendations:
1. **Embrace Lifelong Learning**: The pace of technological change means that continuous learning is more important than ever. Junior professionals should seek to expand their skill sets beyond basic tasks that AI can perform. This could include learning about AI and machine learning themselves, gaining a deeper understanding of advanced programming concepts, or developing skills in areas that require a human touch, such as creative thinking and problem-solving.
2. **Focus on Soft Skills**: While AI can handle many technical tasks, soft skills such as communication, teamwork, and leadership remain uniquely human. These skills are critical in roles that involve collaboration and strategic decision-making. Junior professionals should focus on honing these abilities, as they are less likely to be replicated by machines.
3. **Specialize**: Specialization in a niche area can provide a buffer against automation. Whether it's becoming an expert in a specific programming language, mastering a particular type of content creation, or focusing on a unique aspect of UX design, deep expertise in a specialized field can make a professional more valuable and harder to replace.
4. **Leverage AI as a Tool**: Rather than viewing AI purely as a threat, junior professionals should learn to leverage AI tools to enhance their productivity and creativity. Understanding how to effectively use AI can turn it into a powerful ally, helping to perform tasks more efficiently and freeing up time for more complex and rewarding work.
5. **Seek Out Mentorship and Networking**: Building relationships with experienced professionals can provide guidance and opportunities that might not be readily apparent. Mentors can offer insights into industry trends, advice on skill development, and potentially open doors to new roles that are less susceptible to automation.
#### Conclusion
The rise of AI undeniably presents challenges for junior-level professionals, but it also offers opportunities for growth and adaptation. By embracing continuous learning, focusing on soft skills, specializing, leveraging AI tools, and seeking mentorship, individuals can navigate this evolving landscape successfully. The key lies in staying adaptable and proactive, ensuring that as AI continues to advance, human professionals remain indispensable contributors to the workforce. | elukuro |

## Accept the differences - Humans are not systems and vice versa
The debate is as old as mankind. Some argue that values in systems must be human-readable because the user is human. Others want to force the user to deal with technical values because they are already used by the system.
Have you ever typed a UUID from a letter? If so, I have great respect and at the same time pity for you. UUIDs are designed for systems, not for people. On the other hand, business identifiers, like invoice numbers, are not designed for reliable relationships in systems, especially not in modern distributed microservices.
In computer science, we have the principle of '_[separation of concerns](https://en.wikipedia.org/wiki/Separation_of_concerns)_'. It says that you should divide your program into distinct sections. If you follow this principle, you benefit from more freedom of use.
It can also save us unnecessary headaches when designing the solution. We can still use UUIDs for internal system IDs. In the rare cases where we need to communicate with a human, use a specially designed human-friendly identifier. I will now give a guideline on how to design it.
***
## Requirements - select what needs to be met
Requirements always depend on the context. I will provide a list of requirements based on my experience. If some of the requirements are not necessary for you, feel free to leave some out. If you have additional requirements, please leave a comment. I would appreciate it if you explain why you have these requirements so that I can learn from you.
- **(R)** It must be easy to read by humans.
- **(P)** Errors of perception must be avoided.
- **(W)** It must be easy to spell, hand-write, and type by humans.
- **(O)** It must be easy to read by optical character recognition.
- **(S)** It must be hard to guess.
- **(U)** It must be unique for the related entity.
**_R_** This ensures that users can quickly and accurately interpret the identifier without confusion or difficulty. By prioritizing readability, we aim to improve the user experience and streamline the use of the identifier in different contexts.
**_P_** It is important to design the identifier in a way that minimizes misinterpretation. By prioritizing clarity and distinctiveness, we aim to reduce the risk of misreading the identifier.
**_W_** This ensures ease of use across multiple communication channels and input methods. We aim to make communication and data entry seamless for users.
**_O_** This ensures that the identifier can be accurately scanned and processed by machines, increasing efficiency and automation in various applications. By designing the identifier with OCR readability in mind, we ensure compatibility with modern technology and data processing workflows.
**_S_** It is important to make the identifier sufficiently complex and unpredictable to prevent unauthorized access or manipulation. Our goal is to enhance security and protect the integrity of the identifier and associated data.
**_U_** By enforcing uniqueness, we maintain data integrity and facilitate accurate referencing and retrieval of information. Each entity is uniquely identified without any overlap or duplication.
From time to time in this article, I will refer to these requirements with the letter at the beginning. This means that I have taken this particular requirement into account when designing a human-friendly identifier.
***
## Characters - make the identifier easy to read
To generate the identifier, we need a specific set of characters. We have to choose this collection carefully because it affects readability **(R)**, perception **(P)**, and writing **(W)**. Ensuring the suitability of these characters is essential to their effectiveness in interacting with humans.
In addition to the characters, the choice of font we use is important in terms of readability **(R)**. Have a look at the appearance of the following characters in print. As you can see in the image below, it is hard to tell the difference even when you see them side by side. Imagine how difficult it would be if you could only see one character. We need to choose a font that makes it easier to distinguish between the characters.
The use of both lowercase and uppercase letters also raises the question of whether the reader needs to use a case-sensitive identifier in a written or typed response. A program cannot easily normalize the input to avoid errors. If the character set contains only uppercase letters, we can easily convert any input to uppercase. This choice also removes the small _"l"_ problem.
We need as many characters as possible to ensure uniqueness **(U)** and to keep the identifier short **(R)**. By adding numbers, we increase the number of possible characters. On the other hand, it creates a problem with the uppercase _"O"_ and the zero, as they look very similar in any font.
We can remove one of them from the set. As a reader of the identifier, you do not know that we omitted only one character and which one. I have seen several times that there is a note describing whether both zero and _"O"_ or only one of them is used. If we remove both characters, we avoid any kind of confusion for the human **(R)**.
If you live in a country like Germany, where they even print out electronic receipts and still use real paper letters (to the rest of the world: this article was written in 2024!). It is also important to consider that someone will reply handwritten **(W)**.
To OCR **(O)**, a handwritten _"1"_ may look like an _"I"_. Removing just one of them, preferably the _"I"_, is useful in this case because we can normalize the input to replace a recognized _"I"_ with a _"1"_. The number one is more likely to be recognized differently from other characters. By excluding the _"I"_, we also make it easier to recognize the characters as there is no conflict with the small _"l"_ **(R)**.
This leaves us with the following charset:
> ABCDEFGHJKLMNPQRSTUVWXYZ12345679
***
## Length - how much do you really need?
In general, it is a good idea to use a wide set of characters as it affects the number of unique identifiers you can generate **(U)**. When you use a narrow character set because of the reason above, you have to increase the length of your identifier to allow more recombination.
The number of possible combinations is calculated as follows:
We have to keep the identifier reasonably short. Long identifiers can be difficult to remember and read **(R)**. If you ever run out of combinations because your business scales up like hell, just increase the length for new identifiers. You can keep the old one instead of setting yourself up for success which will never happen if you use too long identifiers.
With a length of only 8, there are 1,099,511,627,776 combinations, which is enough for most of the time. That is 140 times the number of people in the world. Look at this example, close your eyes, and try to remember it:
> AKL1U9ZW
On the other hand, sometimes an identifier needs to be hard to guess **(S)** when used in a security context. Using a length that is too small makes it more likely that a valid identifier will be found by brute-force attacks. It also makes it more likely that a typo will lead to another valid identifier **(U)****(W)**.
Using the character set from the example above and a length of 16 we get the astronomically large number of 1,208,925,819,614,629,174,706,176 combinations. Try to remember the following example as you did it before. Not so easy anymore, right?
> AKL1U9ZWKWA6QPAB
***
## Display - the best way to recognize it
The identifier itself is a random, uninterrupted combination of characters. It has no obvious meaning or context. The human brain tends to look for familiar patterns. Since there are none here, it is very difficult to recognize each of the characters.
Remember the [tally marks](https://en.wikipedia.org/wiki/Tally_marks) we used when we were kids? After drawing four vertical lines, the fifth line is drawn diagonally across the previous four lines. This groups five of the strokes together to make counting easier.
Grouping items helps people to understand and organize information more quickly and efficiently. This is also known as the "[law of proximity](https://en.wikipedia.org/wiki/Principles_of_grouping)". We cannot stroke our characters, but we can use a separator between them. We can use dashes, minuses, hyphens, or slashes, as UUIDs use minus. But when you type or spell the identifier, don't you always wonder if you can leave out the separators?
As children, we would never write the tally marks with a minus or even a slash between them. Such characters were not in our minds at that time. Children always use the simplest and most obvious solution. After five strokes, we leave a little space to group them even more. In the following example the second line is easier to read, right?
We can do the same simple trick with our identifier and use spaces as separators **(P)**. These separators are not even visible to humans. When we process the input for a computer we can normalize it by removing all the spaces between the characters. This makes it as easy as possible for humans to type the identifier. And when you spell the identifier hopefully you will not even notice that there is a hidden separator.
After how many elements should we use a separator? According to "[Miller's Law](https://en.wikipedia.org/wiki/Miller's_law)", people can remember about seven elements. The exact number depends on the person, so we will use the lower limit to include everyone **(P)**. Other publications tend to define this lower bound as only four elements. This is exactly the number we used with the tally marks. See the result:
> AKL1 U9ZW HKAL BCND
As you may have noticed, we are not the only ones using this rule. IBAN or credit card numbers are grouped the same way. I am pretty sure there are more real-life examples in your cultural context to convince you that this idea is widely adopted.
***
## Random - at least pseudo and safe
The identifier should be randomly generated using a cryptographically secure algorithm **(S)**. This makes it easier for you to pass a pen test, especially in a security-critical scenario. Proactively demonstrating that you have taken this into account during design increases confidence in your overall solution.
Even in non-security scenarios, you want to avoid using auto-incrementing numbers. The recipient of an invoice with invoice number _"5"_ does not need to know that you have only written five invoices this year. Hiding this information is also in the best interest of the business.
Note that the identifier is not globally unique like UUIDs. The generation algorithm is pseudorandom, and the length is shorter so that we have fewer combinations. To make it unique for a given entity, you must ensure this using a shared state between concurrent processes, such as a unique constraint on a database **(U)**.
***
## Summary
- Use the character set ABCDEFGHJKLMNPQRSTUVWXYZ12345679
- Generate randomly an identifier with a length of 4 or 8
- To display it to humans insert a space after four characters
- On human input remove spaces and replace _"I"_ with _"1"_

1,922,181 | Explore how BitPower Loop works | BitPower Loop is a decentralized lending platform based on blockchain technology that aims to provide... | 0 | 2024-07-13T11:41:14 | https://dev.to/asfg_f674197abb5d7428062d/explore-how-bitpower-loop-works-48e0 |
BitPower Loop is a decentralized lending platform based on blockchain technology that aims to provide secure, efficient and transparent lending services. Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.
4️⃣ Dynamic interest rates
The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary
BitPower Loop provides a safe, efficient and transparent lending platform through its smart contract technology, decentralized lending model, dynamic interest rate mechanism and global services, providing users with flexible asset management and lending solutions.

1,922,184 | Three important steps before jumping to the code | Once you decide which feature you want to build, it’s time to decide how to actually build it. Over... | 0 | 2024-07-13T11:50:10 | https://stebunov.com/three-steps/ | webdev, programming, productivity, development | Once you decide which feature you want to build, it’s time to decide how to actually build it. Over the years, I have participated in dozens of software development projects as a developer and engineering manager. I have built many features myself and have been lucky to collaborate with many talented people and watch how they work.
Below is my go-to checklist for starting work on a new feature. It’s based on my experience and the teams I supervised – what worked well, and if problems arise, where did they stem from? Of course, the approach I propose here might not fit every situation. However, so many problems in my practice fall into these three buckets that I thought it was worth treating them as a checklist:
## #1: Understand “why”
- Who will be using this feature?
- What problem are we trying to solve for them?
- Why are we going to solve it this way?
Sometimes, developers skip these fundamental questions and jump right into the code. It’s understandable. They’re eager to do what they love, and also, isn’t it the product manager’s job to think about such questions? Well, yes, it certainly is; but that doesn’t mean this information is useless for us developers.
While working on a feature, we face many decisions on all levels, from “How do I name this variable?” to “We ran into a technical issue and need to find a workaround.” A deep understanding of the task context is crucial for making informed decisions. It’s also worth thinking a bit ahead:
- How may this functionality evolve in the future?
- How much data may we need to store?
- Which system failures will cause a bad user experience, and how will we handle that?
- … and so on.
The answers to these and similar questions make the difference between great and poorly designed software. And, once again, we need to understand the task context to get it right.
In an ideal world, the answers to the most important questions will be found or inferred from the task description itself: who the users of this feature are, what problem we will be solving, and why we are going to solve it this way. In practice, this is not always the case, and sometimes developers are shy about asking or think it’s none of their business. Please don’t skip this step. Not only will it help you solve this particular problem at hand better, but it’s also essential for your professional growth.
## #2: UX design
Regardless of the interface you’re building — a UI, API, or command line — consider the user interface carefully before jumping to writing code.
If someone else has already prepared the designs, that’s awesome; so, study them thoroughly first. You might spot problems or inconsistencies and will be able to report them to the designer early on. Even if everything is clear and reasonable, it’s still time well spent because now you have a much better understanding of what you’re building.
If there are no designs yet, and you’re supposed to come up with something, make sure to work on the designs before the code! Some developers, when tasked with building a UI, tend to postpone it because they’re not so confident about their design skills and prefer to start with something else – something they’re more familiar with. Don’t do that. Understanding how users will interact with the system should be your top priority. It’ll likely save you a lot of development work time, and the result will be much better.
You can still produce something useful even if you’re not a professional designer. For example, you can use a rapid wireframing tool like [Balsamiq](https://balsamiq.com/) (my favorite) or [Excalidraw](https://excalidraw.com/). With such tools, you can sketch an idea quickly without spending time on minor visual details. Or, use a whiteboard or good old pencil and paper. Any sketch is better than nothing.
*Low-fidelity [Balsamiq](https://balsamiq.com/) wireframes*
And if you’re building an API or a command-line interface, your design would be the documentation and usage examples. It doesn’t have to be polished at this stage but should include at least the most important use cases.
## #3 - Data structures
> “Bad programmers worry about the code. Good programmers worry about data structures and their relationships.” - Linus Torvalds.
> “Smart data structures and dumb code works a lot better than the other way around.” - Eric S. Raymond.
Yes, data structures are important. Depending on the task, we may optimize them for data consistency, speed, storage requirements, and developer experience; and how we organize data may have vast implications in all of these dimensions. However, the reason why they’re on my list is something else:
**Data structures are harder to change.** If we modify a data structure, we’ll have to update all the code that works with it and also migrate the existing data to the new structure, which can be quite a challenge depending on the project stage and size. As a result, data structures often live longer than the original code that was shipped with them. Also, building more features on top of existing data structures is quite common, so it makes sense to try to make them future-proof to some degree.
This is why data structures are #3 on my list. After we study the task context and understand how users will interact with the system, this is the next important thing to tackle. We can certainly revise data structures later while working on a feature, maybe even multiple times, but given their importance and potentially problematic updates, we should start working on them as early as possible in the process.
If the project is based on a relational database and the feature you’re working on uses multiple tables, it might be a good idea to visualize it using an ER diagram. ER diagrams are arguably the most useful part of the UML specification. You may skip everything else in UML, but if you’re working with relational databases, don’t skip ER diagrams :)

## Summary
When you start working on a new feature:
1. Understand “why”;
2. Review UX designs or create your own;
3. Design data structures;
4. Code.
In that order.

1,922,193 | Handling Flaky Tests in Cypress: Best Practices and Strategies | Introduction Flaky tests are a common challenge in automated testing. They are tests that... | 0 | 2024-07-14T11:18:14 | https://dev.to/aswani25/handling-flaky-tests-in-cypress-best-practices-and-strategies-2cme | webdev, javascript, testing, cypress | ## Introduction
Flaky tests are a common challenge in automated testing. They are tests that sometimes pass and sometimes fail for reasons unrelated to code changes, leading to inconsistent and unreliable test results. In this post, we’ll explore the causes of flaky tests in Cypress and discuss best practices and strategies to handle them effectively.
## What Are Flaky Tests?
Flaky tests are tests that exhibit non-deterministic behavior, meaning they don't always produce the same result when run under the same conditions. This inconsistency can undermine the reliability of your test suite and erode confidence in your automated tests.
## Common Causes of Flaky Tests
1. **Timing Issues:** Tests that depend on asynchronous operations or dynamic content loading can fail if the expected conditions are not met within the given time.
2. **Environment Dependence:** Tests that are influenced by external factors like network speed, server response time, or environment configuration can be flaky.
3. **Resource Contention:** Tests that rely on shared resources or perform actions that affect the state of the application can cause race conditions.
4. **Dependencies on External Services:** Tests that depend on third-party APIs or services can fail due to external service downtime or rate limiting.
5. **Improper Test Isolation:** Tests that do not properly reset or isolate the application state can fail due to leftover data or side effects from previous tests.
## Best Practices for Handling Flaky Tests in Cypress
- **Use `cy.intercept()` for Network Requests:** Stub network requests to control the responses and reduce dependency on external services.
```js
cy.intercept('GET', '/api/data', { fixture: 'data.json' }).as('getData');
cy.visit('/');
cy.wait('@getData');
```
- **Leverage `cy.wait()` Wisely:** Use `cy.wait()` to wait for specific conditions or events instead of arbitrary time periods.
```js
cy.get('.spinner').should('not.exist'); // Ensure spinner is gone
cy.get('.data-list').should('be.visible'); // Ensure data list is visible
```
- **Implement Custom Commands:** Create custom commands to encapsulate common actions and ensure they are performed consistently.
```js
Cypress.Commands.add('login', (username, password) => {
cy.get('input[name="username"]').type(username);
cy.get('input[name="password"]').type(password);
cy.get('button[type="submit"]').click();
cy.url().should('include', '/dashboard');
});
```
- **Use `cy.retry()` Plugin:** Install the Cypress retry plugin to automatically retry failed assertions.
```js
// Install the plugin first: npm install -D cypress-plugin-retries
require('cypress-plugin-retries');
// Enable retries in your test
Cypress.env('RETRIES', 2);
// Example test with retries
it('should display data after retry', () => {
cy.visit('/data-page');
cy.get('.data-item').should('have.length', 10); // Retry if fails
});
```
- **Isolate Tests:** Ensure each test runs in isolation by properly resetting the application state before and after each test.
```js
beforeEach(() => {
cy.exec('npm run reset-db'); // Reset the database
cy.visit('/');
});
```
- **Optimize Selectors:** Use robust and stable selectors to target elements, reducing the likelihood of selector-related flakiness.
```js
// Use data attributes for selectors
cy.get('[data-cy="submit-button"]').click();
```
## Debugging Flaky Tests
1. **Run Tests Locally:** Run the flaky test locally using `cypress open` to observe its behavior and identify potential issues.
2. **Use Debugging Tools:** Utilize Cypress’s built-in debugging tools like `cy.debug()` and browser DevTools to inspect the application state.
3. **Analyze Logs and Screenshots:** Review Cypress logs, screenshots, and videos to pinpoint the cause of flakiness.
## Example: Handling a Flaky Test in Cypress
```js
describe('Flaky Test Example', () => {
beforeEach(() => {
cy.visit('/');
});
it('should load data reliably', () => {
// Use intercept to stub network request
cy.intercept('GET', '/api/data', { fixture: 'data.json' }).as('getData');
cy.get('button[data-cy="load-data"]').click();
cy.wait('@getData');
// Use robust selector and assertion
cy.get('[data-cy="data-list"]').should('have.length', 5);
});
it('should handle spinner correctly', () => {
// Ensure spinner is not visible before asserting data
cy.get('.spinner').should('not.exist');
cy.get('[data-cy="data-list"]').should('be.visible');
});
});
```
## Conclusion
Handling flaky tests is crucial for maintaining a reliable and robust test suite. By understanding the common causes of flakiness and implementing best practices, you can significantly reduce the occurrence of flaky tests in your Cypress projects. Remember to leverage Cypress’s powerful features and tools to ensure your tests are deterministic, isolated, and stable.
Happy testing! | aswani25 |

One guy on Reddit asked if ‘ being a software engineer feels like being a prisoner. ‘ It got me thinking.
Let’s get philosophical here for a sec. Being a prisoner is more a state of mind than just being confined to four walls. When you compare the life of a typical prisoner to that of a Buddhist monk, you’ll notice that prisoners usually have more privileges than a typical monk. Ajahn Brahm famously explained this after he visited a prison: “Any place you don’t want to be is a prison.”
Now, let’s talk about coding. Picture this: you’re at your keyboard, building an entirely new world in your mind. Your work is this incredibly abstract, almost magical process. You start to live in that work, your fingers dancing over the keys like a maestro conducting a symphony. For hours, most of your mind stops reacting to input from the physical world. Your mind roams free in the new virtual world you’ve created. It’s like being the architect of the Matrix, but with less leather and more coffee.
So, yeah, coding might feel a bit like being a prisoner sometimes, especially when the bugs are relentless, and deadlines loom. But really, it’s more like being a prisoner with a key to your own cell, where the cell happens to be an epic fantasy world of your own making. It’s a mental adventure with the occasional dragon (or, you know, a really stubborn line of code).
In the end, whether you feel trapped or free as a bird is all in your head. And if you’re ever feeling too confined, just remember: you can always turn off your computer, step outside for a walk, and maybe even sit in meditation for a while. Trust me, your virtual world will still be there when you get back.

So.. I was working as a developer, working on .net stack. We were maintaining a few (40+) .net applications for between 3 developers. We constantly got revision requests and we used to have zero time between the three of us to manage them. We managed to cut it down by engaging with the customers (more about it another day) . Then came a new request: we needed a new application to track all of the sites we were looking after (100+) plus their divisions (25+).
I was asked to look at potential solution by my manager (I'll name him later with his permission), to whom I suggested I'll have a look and come back.
I explored OutSystems (very clumsy in my opinion), Salesforce (could not get a trial lol), .Net Rapid App Development Tools (still complicated) and Microsoft PowerApps. I was blown away by Powerapps even if it felt a bit under powered compared to its peers.
I figured I could use a teams site to spin up a SharePoint Online (SPO) instance (IT red tape around SharePoint meant a week and two business cases plus five approvals before we got our own SPO instance). Then, I used for SharePoint Online list as a data source after doing some research as it was kinda fast, secure (tenancy settings) and most importantly free and required no additional licences.
I built a prototype in two days along with another colleague and sent it to my manager to have a look at. We ensured mobile friendliness from the start.
One hour later, I got a message in outlook.
“Your big boss wants access to your application”.
I checked with my manager as I was kinda nervous, who said there was no need to worry as the application was quite awesome. I sent a approval email to the big boss who then came back to us asking for the application to be built and assigned us a Project Manager to work with.
In three months, I built the application with the following features:
- 5 different question types based on what the user selected as their site.
- Map visualising the responses in real time
- Task based functionality to log any issues
- Approval workflow where staffs could nominate new users to have access and the application admin could approve and it would start an onboarding process
- Color coded response view with filters
We had an amazing team of 2 who worked on an amazing PowerBI dashboard for execs and meetings.
The application was quite simple, we used basic colors and no fancy animations and we always ensured mobile 📱-first design.
The app was a canvas app of course and did not have any premium licensing because of the SPO list use. We then created an environment for Dev and another for production and then went with deployment. We did 600+ commits and finally the application was ready to be launched.
The week of launch, I was told that each user had to be individually added. I was thinking of active directory groups but that would mean getting additional approvals so we went with a new approach. We would modify the approval process using power automate to bulk insert the users and approve them individually. Once approved, they would get a pdf and a link to the application.
This saved us so much time in user support as I personally onboarded 700 users in a week with only 2 people reaching out for app issues. We had 1000+ users in 2 weeks who were using it 24*7 and were using the application to provide valuable insight to the other team members and the execs.
The launch was a huge success and I felt very proud to have built it. I then realised, I can replicate what I’d done there and kinda make a career out of it.
That's the story folks, will share another story next week.

Polkadot mushroom chocolate is making waves in both the culinary and psychedelic communities. This fascinating fusion of psilocybin mushrooms and delectable chocolate offers a unique experience that’s as intriguing as it is delicious. But what exactly is polkadot mushroom chocolate, and why is it gaining popularity? Let’s dive into this captivating topic.
What is Polkadot Mushroom Chocolate?
Polkadot mushroom chocolate is a carefully crafted confection that combines psilocybin mushrooms, known for their psychoactive properties, with high-quality chocolate. The result is a treat that not only delights the taste buds but also offers a potential journey into altered states of consciousness.
The Science Behind Polkadot Mushroom Chocolate
At the heart of [polkadot mushroom chocolate](https://realchocolatebar.com/) are two key components: psilocybin and chocolate.

Cons: Risk of overconsumption due to the delicious taste, variable potency.
The Culinary Aspect
Flavor Profile
Polkadot mushroom chocolate typically has a rich, earthy flavor complemented by the sweetness and bitterness of chocolate. The type of chocolate used can significantly influence the overall taste.
Pairing Suggestions
Pairing polkadot mushroom chocolate with complementary flavors like nuts, berries, or a fine wine can elevate the experience. The goal is to enhance the overall sensory journey.
Polkadot Mushroom Chocolate Recipes
Basic Homemade Recipe

For web developers in the digital era of today, security has taken front stage. The terrain of cyber threats is always changing as we enter 2024, thus it is vital to use the most recent security policies to safeguard your web apps. Whether your experience level is high or low, knowing and applying these best practices is absolutely vital. Our area of expertise at iTechTribe International is creating strong, safe web apps specifically for your use. These are some best practices to keep your 2024 web apps safe.
**1. Use TLS everywhere.**
It is not optional anymore to make sure your online application runs HTTPS; it is rather required. Between the user's browser and your server, HTTPS encrypts the data moved to guard against interception and manipulation. Verify that your whole website - not only the login pages - is delivered across HTTPS.
**2. apply robust authentication.**
First line of protection against illegal access is authentication. Add even more protection using multi-factor authentication (MFA). Strong password rules should also be followed, mandating users to create complicated passwords and support the usage of password managers.
**3. Frequent Dependency Update**
Older libraries and systems could bring weaknesses. Update your dependencies often to their most recent versions, then apply fixes right away upon release. By tracking your dependables for known flaws, tools like Dependabot or Snyk may help automate this process.
**4. Apply Safe Coding Techniques**
Change your coding style to reduce code vulnerabilities. This covers parameterized searches, prepared statements, and user input validation to stop SQL injection threats. Furthermore steer clear of hardcoded secrets in your code and substitute environment variables.
**5. Use Correct Session Management**
Web security depends critically on sessions. Make sure session IDs are complicated and rebuilt following login to stop session fixation attempts. Establish reasonable session times and save session tokens using safe, HTTP-only cookies.
**6. Prevent Cross-Site Scripting (XSS)**
Devastating cross-site scripting exploits let attackers run hostile programs in the user's browser. Headers in Content Security Policy (CSP) will help to limit the sources from which scripts may load. Clean and escape user inputs to stop hostile script injection.
**7. Guarantuate Data Privacy**
Particularly with laws like GDPR and CCPA, data protection is first concern. Put policies in place to guard private user information including both in-flight and at rest encryption. Check your data storage methods often to guarantee adherence to pertinent laws.
**8. Plan frequent security audits.**
Regular security audits and penetration testing help find weaknesses before attackers do. For ongoing scanning, use automated tools as OWASP ZAP or Burp Suite. You should also think about doing extensive penetration tests by involving security experts.
**At last**
Keeping ahead with the newest security techniques is absolutely vital as cyber threats change. Following these best standards will help you create safe online applications safeguarding your consumers and company. Our dedication at [iTechTribe International](https://itechtribeint.com/) is to provide strong and safe online solutions. Let our professionals assist you to create a safe online application. See our website iTechTribe International to find more about our offerings and how we could help you create a safe, future-proof online application.

Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.
4️⃣ Dynamic interest rates
The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary
BitPower Loop provides a safe, efficient and transparent lending platform through its smart contract technology, decentralized lending model, dynamic interest rate mechanism and global services, providing users with flexible asset management and lending solutions.

By delivering a unified and cohesive brand experience, businesses can strengthen their brand identity, build customer loyalty, and ultimately drive better marketing performance.
Strategic Marketing Integration is a comprehensive approach that combines various marketing elements to deliver a unified and cohesive message across multiple channels. It differs from traditional marketing approaches in several key aspects.
## Key Components and Principles
Integrated Marketing Communications (IMC): IMC is a crucial component that ensures consistency in messaging and branding across all marketing channels, including advertising, public relations, social media, and direct marketing.
**Multichannel Approach:** Strategic Marketing Integration leverages multiple channels to reach customers, providing a seamless experience across various touchpoints.
**Customer-Centric Focus:** It emphasizes understanding customers' needs, preferences, and behaviors to craft personalized and relevant marketing strategies.
**Data-Driven Insights:** Strategic Marketing Integration relies heavily on data analytics to make informed decisions, measure campaign performance, and optimize marketing efforts.
**Cross-functional collaboration:** This involves collaboration across different departments, such as marketing, sales, and product development, to align strategies and ensure a cohesive brand experience.
## Differences from Traditional Marketing Approaches
Integration vs. Fragmentation: Traditional marketing often operates in siloed channels, resulting in fragmented and inconsistent messaging. Strategic Marketing Integration aims to create a unified and integrated approach.
**Customer-Centric vs. Product-Centric:** While traditional marketing tends to focus on promoting products, Strategic Marketing Integration adopts a customer-centric mindset, tailoring strategies to meet customer needs and preferences.
**Continuous Optimization vs. Campaign-Based:** Traditional marketing often revolves around individual campaigns with a set start and end date. Strategic Marketing Integration is an ongoing process that continuously optimizes strategies based on data and customer feedback.
**Multichannel vs. Single-Channel:** Traditional marketing may focus on a single channel, such as television or print advertising. Strategic Marketing Integration leverages multiple channels to reach customers wherever they are.
**Cross-Functional Alignment vs. Departmental Silos:** Strategic Marketing Integration requires cross-functional collaboration and alignment, breaking down departmental silos that can exist in traditional marketing approaches.
In summary, Strategic Marketing Integration is a holistic and customer-centric approach that integrates various marketing components and leverages data-driven insights to deliver a consistent and personalized brand experience across multiple channels.
## Advantages of Strategic Marketing Integration
Strategic marketing integration refers to the coordination and alignment of various marketing activities and channels to deliver a consistent and cohesive brand message. This approach offers several key advantages:
**Enhanced Consistency and Coherence in Messaging**
An integrated marketing strategy ensures that all marketing efforts, across different platforms and touchpoints, communicate a unified brand voice and messaging. This consistency reinforces brand recognition and prevents mixed signals that could confuse or alienate customers.
**Improved Targeting and Segmentation of Audiences**
By integrating data from various marketing channels, businesses can gain a more comprehensive understanding of their target audiences. This allows for more effective audience segmentation and personalized messaging tailored to specific customer preferences and behaviors.
**Increased Efficiency and Cost-Effectiveness**

1,922,234 | Responsive Web Design: Techniques Using Media Queries, Viewport Units, and Fluid Layouts | Responsive web design (RWD) is a design approach that ensures web content adjusts smoothly across... | 0 | 2024-07-13T12:24:28 | https://dev.to/mdhassanpatwary/responsive-web-design-techniques-using-media-queries-viewport-units-and-fluid-layouts-31el | webdev, css, learning, productivity |
Responsive web design (RWD) is a design approach that ensures web content adjusts smoothly across various devices and screen sizes. With an ever-growing array of devices, including smartphones, tablets, and desktop monitors, it's crucial to create websites that provide an optimal viewing experience for users regardless of their device. This article will explore essential techniques for achieving responsive web design, focusing on media queries, viewport units, and fluid layouts.
## 1. Media Queries
**Media queries** are a cornerstone of responsive web design. They allow developers to apply CSS styles based on the characteristics of the device, such as its width, height, and orientation. By using media queries, you can create distinct layouts for different screen sizes.
### Example: Basic Media Query
```
/* Default styles for mobile devices */
body {
font-size: 16px;
padding: 10px;
}
/* Styles for tablets and above */
@media (min-width: 768px) {
body {
font-size: 18px;
padding: 20px;
}
}
/* Styles for desktops and above */
@media (min-width: 1024px) {
body {
font-size: 20px;
padding: 30px;
}
}
```
In this example, the font size and padding increase as the screen width grows, providing a better reading experience on larger devices.
### Example: Orientation-Based Media Query
```
/* Styles for landscape orientation */
@media (orientation: landscape) {
body {
background-color: lightblue;
}
}
/* Styles for portrait orientation */
@media (orientation: portrait) {
body {
background-color: lightgreen;
}
}
```
Here, the background color changes based on the device's orientation, enhancing the visual appeal.
## 2. Viewport Units
**Viewport units** are relative units that make it easy to create scalable designs. They include `vw` (viewport width) and `vh` (viewport height), which are a percentage of the viewport's dimensions. These units are particularly useful for setting dimensions and spacing that adapt to the viewport size.
### Example: Viewport Units in Action
```
/* Full-width container */
.container {
width: 100vw;
background-color: lightcoral;
}
```
In this example, the container spans the full width of the viewport, ensuring it adapts to different screen sizes.
## 3. Fluid Layouts
**Fluid layouts** use relative units like percentages instead of fixed units like pixels, allowing elements to resize in proportion to their container. This technique ensures that layouts adapt seamlessly to different screen sizes.
### Example: Fluid Layout with Percentages
```
/* Fluid grid container */
.grid {
display: flex;
flex-wrap: wrap;
}
/* Fluid grid items */
.grid-item {
flex: 1 1 100%;
padding: 10px;
box-sizing: border-box;
}
/* Adjusting grid items for larger screens */
@media (min-width: 768px) {
.grid-item {
flex: 1 1 48%;
}
}
@media (min-width: 1024px) {
.grid-item {
flex: 1 1 31%;
}
}
```
In this example, grid items take up 100% of the container width on small screens. As the screen width increases, the items resize to occupy 48% and then 31% of the container, creating a responsive grid layout.
### Responsive Font Sizes with Clamp()
Using the `clamp()` function allows you to create fluid typography that adjusts smoothly across different screen sizes. The `clamp()` function takes three values: a minimum value, a preferred value, and a maximum value.
Example: Responsive Font Sizes with Clamp
```
/* Responsive typography using clamp() */
h1 {
font-size: clamp(1.5rem, 2vw + 1rem, 3rem);
margin-bottom: clamp(1rem, 1.5vw, 2rem);
}
```
In this example, the font size of the heading will scale between 1.5rem and 3rem, depending on the viewport width, ensuring it remains readable on all devices.
### Combining Techniques
Combining media queries, viewport units, and fluid layouts allows you to create highly responsive and flexible web designs.
### Example: Combined Techniques
```
/* Base styles */
body {
font-size: clamp(1rem, 1.5vw, 1.5rem); /* Responsive typography */
margin: 0;
padding: 0;
}
.header {
height: clamp(3rem, 5vw, 5rem); /* Responsive header height */
background-color: #333;
color: white;
display: flex;
align-items: center;
justify-content: center;
}
/* Responsive grid */
.grid {
display: flex;
flex-wrap: wrap;
}
.grid-item {
flex: 1 1 100%;
padding: 10px;
box-sizing: border-box;
}
@media (min-width: 768px) {
.grid-item {
flex: 1 1 48%;
}
}
@media (min-width: 1024px) {
.grid-item {
flex: 1 1 31%;
}
}
```
In this combined example, the typography scales with the viewport using the `clamp()` function, the header height is responsive using `clamp()`, and the grid layout adjusts based on screen size. This approach ensures a cohesive and adaptive design across all devices.
## Conclusion
Responsive web design is essential in today's multi-device world. By leveraging media queries, viewport units, and fluid layouts, you can create websites that provide an optimal viewing experience on any screen size. These techniques ensure your web content is accessible, visually appealing, and functional, regardless of the device your audience uses. Embrace these practices to enhance the usability and aesthetics of your web projects, delivering a seamless experience to all users. | mdhassanpatwary |

BitPower: A decentralized lending protocol with outstanding security
With the development of blockchain technology, decentralized finance (DeFi) has gradually become an important part of the financial technology field. In this field, BitPower, as a decentralized lending protocol, stands out with its unique security and transparency. This article will explore the security features of BitPower and analyze its application in decentralized lending.
BitPower uses smart contract technology to realize automated and trustless lending processes. Smart contracts execute predetermined logic through code, eliminating the existence of intermediaries and ensuring the transparency and security of transactions. All operations are recorded on the blockchain and cannot be tampered with, ensuring the credibility of the system and the integrity of the data. This transparency allows all participants to conduct lending transactions with confidence.
The security of BitPower is first reflected in the audit of its smart contracts. Smart contracts are strictly audited by third-party security companies to ensure that the code is free of vulnerabilities and meets security standards. In addition, BitPower adopts a multi-signature mechanism and time lock to prevent malicious operations and hacker attacks. The multi-signature mechanism requires multiple independent signatories to jointly authorize to perform key operations, thereby improving the security and tamper-proof capabilities of the system.
Secondly, BitPower introduced a mortgage mechanism. Before borrowing, the borrower needs to provide a certain proportion of crypto assets as collateral to ensure the repayment ability of the loan. Once the borrower fails to repay on time, the system will automatically execute the liquidation procedure and use the collateral to repay the loan. This mechanism not only protects the rights and interests of the borrower, but also ensures the safety of the lender's funds and reduces the risk of default.
In addition, BitPower has a risk management module that monitors market fluctuations and user behavior in real time, adjusts the mortgage rate and liquidation parameters in time, and ensures that the system can still operate stably under extreme market conditions. The combination of the risk management module and the smart contract gives BitPower a high degree of security and risk resistance.
In summary, BitPower provides a safe and reliable solution for decentralized lending with the transparency of its smart contracts, the security of the mortgage mechanism, and the stability of the risk management module. Its outstanding security features not only enhance user trust, but also promote the further development of decentralized finance. In the future, with the continuous advancement of technology, BitPower is expected to occupy a more important position in the DeFi field and continue to provide users with efficient and secure financial services. @Bitpower | pings_iman_934c7bc4590ba4 | |

### How Simple Engineering Works
1. **Frontend** makes a call to **Backend APIs**.
2. **Backend APIs** process the request and send a response back.
3. The **Frontend** renders the response accordingly.
This works pretty well when you're building an MVP.
### What Happens When We Decide to Scale or Mature the Project 🚀
- Backend APIs start following the **[Single Responsibility Principle](https://www.geeksforgeeks.org/single-responsibility-in-solid-design-principle/)**.
- APIs can be grouped together in services, or microservices can be introduced.
- Client-side code becomes more complex.
- Frequent changes in request-response structures become common between frontend and backend.
- More data gets loaded into the frontend.
- When addressing multiple client types (e.g., web and mobile), APIs become more bloated.
- Multiple concurrent requests go to the backend to address page UI demands.
This can become as overwhelming as my girlfriend’s never-ending list of demands. So, to help, one of my senior team-mates introduced me to the concept of **BFF**. Whether in real life or code, BFFs always have your back.
### What the Heck is BFF? 🤔
A **Backend for Frontend (BFF)** is a mediator that tailors backend services to the specific needs of different clients. Think of it as the best friend who filters all the chaos and serves you only what you need. The frontend calls a BFF server API endpoint, and then the BFF does the heavy lifting, calling all the backend services required.
### How BFF Helps with Scaling the Project 🛠️
**Why maintain another mediator server, BFF, in this case? Why not stick to the old and proven two-tier architecture?**
Because now we care about user experience! We’re no longer an MVP and can’t be running around like headless chickens.
Our backend APIs follow the Single Responsibility Principle, but our UI needs a lot of data, which means making calls to many backend APIs. The catch is that most browsers only allow 6 concurrent requests per domain. You can read more on this limitation over this [Stackoverflow thread](https://stackoverflow.com/questions/985431/max-parallel-http-connections-in-a-browser). So, if you have a dashboard showing data from 3-4 services, each with many APIs, the browser can only handle 6 at a time. Once those are done, it processes the next 6. And this is without counting the initial script loading!
**Enter BFF:** The client makes a single call to the BFF, and the BFF makes all the calls to all the services without the parallel connection limitations. Problem solved!
But what if the number of concurrent connections wasn’t the issue? Should you still use the BFF pattern? My answer is a resounding yes!
Imagine you have a dashboard showing data from 3-4 services. You’ll likely be doing some client-specific computation, adaptation, or transformation of data before showing it to the end user. For small chunks, doing this on the client works well. But as the data transformations get more complex, it becomes a bottleneck for user experience. JavaScript is single-threaded, and the UI starts to feel laggy or jittery because the browser is busy transforming data instead of serving the UI.
**A simple fix:** Move all the presentation, adaptation, or transformation logic to the BFF. This way, the client's browser is free to focus on rendering content. Plus, the BFF adapts to any changes in backend API response structures, so the frontend sees a consistent response structure.
**But what about the BFF API becoming too generalized or bloated? Doesn’t it need to follow the Single Responsibility Principle too?**
The single responsibility principle is a bit different for BFF. A single BFF server endpoint should ideally load or update data related to a single UI page. Different client types (like mobile and web) can have their own BFF servers. Each BFF server sends back a thin, tailored response to the client. Mobile has less real estate than web, so the BFF server can easily trim the response.
So, while BFF server APIs might seem bloated and generalized compared to backend service APIs, they still follow the Single Responsibility Principle.
### Using BFF in the Real World 🌍
**Setting Up and Exploring an Open-Source Project**
1. **Project Setup**:
- Follow the steps in the [project's README](https://github.com/middlewarehq/middleware) to set up the project.
- Once the setup is complete and the server is running, visit [https://localhost:3000/dora-metrics](https://localhost:3000/dora-metrics).
2. **Open Network Tab**:
- Open your browser's developer tools (press `F12` or `Ctrl+Shift+I`).
- Go to the 'Network' tab to monitor API calls.
3. **Observe API Calls**:
- Notice that the page loads most of its data from the response of `/internal/team/${team_id}/dora_metrics`.
- This is a BFF API endpoint responsible for loading all the required data for the `/dora-metrics` route page.
4. **Examine the Codebase**:
- Navigate to the code for the `/internal/team/[team_id]/dora_metrics` module.
- Observe the concurrent invocation of multiple backend services using `Promise.all`.
5. **Understand the Benefits**:
- Under the hood, we are calling 5 different backend services and making a total of 18 API calls.
- If the same number of calls were made from the frontend, it could take 3x more time than using the BFF approach.
Following these steps will help you understand how the BFF pattern is implemented in a real-world project and appreciate the benefits it brings in terms of performance and user experience.
### Benefits of Using BFF 🌟
1. **Improved User Experience**: By offloading complex data transformations and aggregations to the BFF, the client's browser can focus on rendering, resulting in a smoother UI experience.
2. **Optimized API Calls**: The BFF can aggregate multiple backend API calls into a single call, reducing the number of requests the client needs to make.
3. **Tailored Responses**: Different clients (web, mobile) can have their specific BFF servers, ensuring that each client receives data tailored to their needs.
4. **Adaptability**: The BFF can adapt to changes in backend API structures, providing a consistent interface to the frontend.
In conclusion, adopting the BFF pattern can significantly improve the scalability, maintainability, and user experience of your application as it evolves from an MVP to a mature product. And remember, whether in code or life, a good BFF always has your back!

BitPower: A decentralized lending protocol with outstanding security
With the development of blockchain technology, decentralized finance (DeFi) has gradually become an important part of the financial technology field. In this field, BitPower, as a decentralized lending protocol, stands out with its unique security and transparency. This article will explore the security features of BitPower and analyze its application in decentralized lending.
BitPower uses smart contract technology to realize automated and trustless lending processes. Smart contracts execute predetermined logic through code, eliminating the existence of intermediaries and ensuring the transparency and security of transactions. All operations are recorded on the blockchain and cannot be tampered with, ensuring the credibility of the system and the integrity of the data. This transparency allows all participants to conduct lending transactions with confidence.
The security of BitPower is first reflected in the audit of its smart contracts. Smart contracts are strictly audited by third-party security companies to ensure that the code is free of vulnerabilities and meets security standards. In addition, BitPower adopts a multi-signature mechanism and time lock to prevent malicious operations and hacker attacks. The multi-signature mechanism requires multiple independent signatories to jointly authorize to perform key operations, thereby improving the security and tamper-proof capabilities of the system.
Secondly, BitPower introduced a mortgage mechanism. Before borrowing, the borrower needs to provide a certain proportion of crypto assets as collateral to ensure the repayment ability of the loan. Once the borrower fails to repay on time, the system will automatically execute the liquidation procedure and use the collateral to repay the loan. This mechanism not only protects the rights and interests of the borrower, but also ensures the safety of the lender's funds and reduces the risk of default.
In addition, BitPower has a risk management module that monitors market fluctuations and user behavior in real time, adjusts the mortgage rate and liquidation parameters in time, and ensures that the system can still operate stably under extreme market conditions. The combination of the risk management module and the smart contract gives BitPower a high degree of security and risk resistance.
In summary, BitPower provides a safe and reliable solution for decentralized lending with the transparency of its smart contracts, the security of the mortgage mechanism, and the stability of the risk management module. Its outstanding security features not only enhance user trust, but also promote the further development of decentralized finance. In the future, with the continuous advancement of technology, BitPower is expected to occupy a more important position in the DeFi field and continue to provide users with efficient and secure financial services. @Bitpower | pingz_iman_38e5b3b23e011f | |

1,922,253 | Tips on how to Pass Your AWS Advanced Networking Specialty Exam ANS-C01 | Good day to all my fellow Aspiring Cloud Network Engineers, Network Architects and Network Engineers.... | 0 | 2024-07-13T12:42:48 | https://dev.to/aws-builders/tips-on-how-to-pass-your-aws-advanced-networking-specialty-exam-ans-c01-55md | cloudcomputing, networking, advanced, aws | Good day to all my fellow Aspiring Cloud Network Engineers, Network Architects and Network Engineers.
Whether you are taking this exam to validate your skills or looking to enhance your skillset, the AWS ANS-C01 will definitely boost your ability and allow you to stand out in terms of Career Progression or Getting into a Cloud Network Engineering Role.
**Background**
I have been in the Cloud Industry now for close too 4 years and the AWS Advanced Network Specialty has always been on my radar since day 1 of my AWS Cloud Practitioner. I always have loved Networking having passed my CompTIA Network + at the young age of 17, I have always been inquisitive of both the capabilities of home networking via hosting LAN parties, all the way to building VPNs to communicate as Hub and Spoke Businesses. Personally I hold my CCNA, CCNP Enterprise Networking & CCNP Security, however even with my strong Networking Background, this course is quite demanding and definitely deserves a solid 4 - 6 months of your time to best Prepare, Tackle and Pass your AWS Networking Specialty.
**Tips**
So I believe in a 3 Step Golden Rule, **Step1**: Enhance your Knowledge with a Good Video Course, I have become accustomed to Cloud Academy, they offer a robust course, easy even for Beginners to Jump in and get started. I would advise though that you should have completed your AWS Solutions Architect Associate Prior to Tackling this course, as its just easier to digest and follow along with having built a good foundation.
**Cloud Academy**
https://cloudacademy.com/learning-paths/aws-advanced-networking-specialty-ans-c01-certification-preparation-for-aws-1-7410/
Cloud Academy is my preferred training partner due to its comprehensive approach to learning. The platform begins with in-depth theoretical lessons, followed by question sets and knowledge checks that evaluate your strengths and weaknesses. This initial assessment ensures that you have a clear understanding of where you excel and where you may need further review before moving on to the hands-on labs.
The labs, which are integrated at the end of each section, provide practical, real-world experience. These labs allow you to revisit instructional videos and take additional notes in areas where improvement is needed, while also enabling you to skip sections where you have demonstrated proficiency. This method not only reinforces the theoretical concepts taught but also helps to solidify your understanding through practical application, ensuring a well-rounded grasp of the subject matter.
Right at the end of the course you will provided with a Practice Exam, this practice exam is aimed at matching the level of the actual exam's difficulty. Each time you attempt the exam a different question set will be provided to you. I recommend you take these at least 5 times and score and average of 90% before taking on the real exam.
Lastly they provide you a Certificate of Excellence once passing and a Badge you can attach to your LinkedIn page, now I feel that's real value for money.
**Step 2**
Adrian Cantrill's course whilst it maybe a little costly I definitely recommend to anyone seeking to gain Professional Real-World Application Labs, whilst I do prefer Cloud Academy's Teaching Style, Adrian Cantrill is second to none when it comes to his professional experience and in-depth level labs. Here are a few examples below:
Multi-Cloud - Site-to-Site VPN Configuration (AWS & Azure) - All running on Free Tier Services (Azure Jumpbox can communicate and RDP to Private Instance in AWS)
1.) Azure: Configured Necessary Resource Group, Virtual Private Gateway, Azure Local Network GW Configs, Azure VNETs, Configured Route Tables, Generated VM Windows 10 Instance. (IPSEC VPN)
2.) AWS: Customer Gateway Configuration, attached to VPC, Configured Route Tables, VPN with Static routing, Configured Security Groups, Configured Site-to-Site VPN IPSEC VPN, used Generic Configuration, Launched PVT Instance Windows Server 2022.
The above is just one of the amazing Labs Adrian walks you through, for more examples check out https://github.com/acantril, if you cannot afford the course, I definitely recommend asking your employer purchasing the course for yourself and your team. It definitely made the difference for me, especially when answering some of the exam questions.
**Step 3**
To round everything up, I would definitely recommend Tutorial Dojo's Practice questions, I personally felt like their Practice exams were actually more difficult than the actual exam itself, the content was spot on and gave me the confidence I needed to evaluate my Exam Readiness. Furthermore the Question sets provide not just the correct answers should review your results, it often provides actual Architectural Diagrams, to make you think like a Cloud Architect but it even Provides Video's to their Content for those Visual Learners whom like Practical Examples.
These are coupled with Links to AWS Documentation as well as to further motivate the correct answer.
Lastly they boast AWS Cheats which are notes on the important Aspects of each domain.
https://tutorialsdojo.com/aws-cheat-sheets-networking-and-content-delivery/
**Extras**
Should time permit, I would absolutely recommend you check out AWS Power Hour Series, I was lucky that the series was hosted whilst I was preparing for the exam and it allowed me to speak with AWS's Trainers and Engage with Like Minded Peers Around the world.
These Videos are available on Demand for you to watch, so head over to https://www.twitch.tv/aws (https://pages.awscloud.com/GLOBAL_TRAINCERT_T2-Twitch-AWS-Power-Hour-Specialty-Certification.html?did=tc_card&trk=tc_card#undefined) and make the best of the series.
I really hope my training Strategy helps better equip you for exam success, best of luck to you all!!!

1,922,254 | A Beginner’s Guide to Web APIs with JavaScript | Introduction In the digital world, Web APIs play a crucial role in allowing different... | 0 | 2024-07-13T12:44:48 | https://dev.to/femiwebdev_/a-beginners-guide-to-web-apis-with-javascript-2ml6 | javascript, beginners, tutorial, webdev | ## Introduction
In the digital world, Web APIs play a crucial role in allowing different software systems to communicate with each other. Whether you're fetching data from a server, integrating payment gateways, or embedding social media feeds on a website, understanding Web APIs is essential for modern web development. This tutorial aims to demystify Web APIs for beginners, using JavaScript as the primary language for examples.
## What are Web APIs?
Web APIs, or Application Programming Interfaces, are sets of rules and protocols that allow different software applications to communicate with each other over the web. They define the methods and data formats that applications can use to request and exchange information. For example, a weather website might use a Web API to fetch current weather data from a remote server.
## Types of Web APIs
There are various types of Web APIs, such as RESTful APIs (Representational State Transfer), SOAP APIs (Simple Object Access Protocol), and GraphQL APIs. Each type has its own conventions and use cases, but for this tutorial, we'll focus on using the Fetch API with RESTful APIs, which is widely used in modern web development for its simplicity and compatibility with JavaScript.
## Getting Started with Fetch API
The Fetch API is a modern, promise-based API for making HTTP requests in JavaScript. It provides a more powerful and flexible way to fetch resources asynchronously from a server.
## Introduction to Fetch API
In JavaScript, you can use the Fetch API to make network requests. It uses promises, which are a way to handle asynchronous operations more conveniently.
```
// Example: Fetching data from a remote server
fetch('https://api.example.com/data')
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json(); // Parse the JSON data
})
.then(data => {
console.log(data); // Process the JSON data
})
.catch(error => {
console.error('There was a problem with the fetch operation:', error);
});
```
## Making GET requests
To fetch data from a server using the Fetch API, you use the fetch() function with the URL of the resource you want to retrieve. The fetch() function returns a promise that resolves to the Response object representing the response to the request.
```
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error fetching data:', error));
```
## Handling JSON responses
Many Web APIs return data in JSON format, which stands for JavaScript Object Notation. To work with JSON responses, you can use the response.json() method to parse the JSON data.
```
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => {
// Work with the JSON data here
console.log(data);
})
.catch(error => console.error('Error fetching JSON:', error));
```
## Error handling
It's important to handle errors when making network requests. You can use the .catch() method to catch any errors that occur during the fetch operation.
```
fetch('https://api.example.com/data')
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('There was a problem with the fetch operation:', error));
```
## Sending Data with Fetch API
In addition to fetching data from a server, the Fetch API can also be used to send data to a server using different HTTP methods, such as POST, PUT, DELETE, etc.
## Making POST requests
To send data to a server using a POST request, you need to include additional options in the fetch() function, such as method, headers, and body.
```
// Example: Sending data to a server using POST method
const formData = new FormData();
formData.append('username', 'john_doe');
formData.append('email', 'john@example.com');
fetch('https://api.example.com/users', {
method: 'POST',
body: formData
})
.then(response => response.json())
.then(data => console.log('User created:', data))
.catch(error => console.error('Error creating user:', error));
```
## Sending form data
When sending form data to a server, you can use the FormData object to construct the data and send it as the body of the POST request.
```
// Example: Sending form data to a server
const formData = new FormData();
formData.append('username', 'john_doe');
formData.append('password', 'secure_password');
fetch('https://api.example.com/login', {
method: 'POST',
body: formData
})
.then(response => response.json())
.then(data => console.log('Login successful:', data))
.catch(error => console.error('Error logging in:', error));
```
## Handling different content types (JSON, FormData)
Depending on the API you are interacting with, you may need to send data in different formats. For JSON data, you can stringify an object and set appropriate headers. For FormData, you can directly pass the FormData object as the body of the request.
```
// Example: Sending JSON data to a server
const postData = {
username: 'john_doe',
password: 'secure_password'
};
fetch('https://api.example.com/login', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify(postData)
})
.then(response => response.json())
.then(data => console.log('Login successful:', data))
.catch(error => console.error('Error logging in:', error));
```
## Working with Asynchronous JavaScript
Understanding how to work with asynchronous operations is crucial when dealing with Web APIs. JavaScript provides several mechanisms to handle asynchronous code, such as Promises and async/await.
### Understanding Promises
Promises are objects that represent the eventual completion or failure of an asynchronous operation. They allow you to handle asynchronous code in a more synchronous-like manner.
```
// Example: Using Promises with Fetch API
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error fetching data:', error));
```
## Using async/await with Fetch API
async/await is a modern approach to writing asynchronous code in JavaScript. It allows you to write asynchronous code that looks synchronous, making it easier to read and maintain.
```
// Example: Using async/await with Fetch API
async function fetchData() {
try {
const response = await fetch('https://api.example.com/data');
if (!response.ok) {
throw new Error('Network response was not ok');
}
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error fetching data:', error);
}
}
fetchData();
```
## Introduction to Other Web APIs
Apart from the Fetch API, there are other Web APIs provided by browsers that you can use in your web applications.
### Geolocation API
The Geolocation API allows you to retrieve the geographical position of a user's device.
### LocalStorage and SessionStorage
LocalStorage and SessionStorage provide a way to store key-value pairs locally in the browser.
```
// Example: Using Geolocation API
if ('geolocation' in navigator) {
navigator.geolocation.getCurrentPosition(position => {
console.log('Latitude:', position.coords.latitude);
console.log('Longitude:', position.coords.longitude);
}, error => {
console.error('Error getting location:', error);
});
} else {
console.error('Geolocation is not supported by this browser');
}
// Example: Using LocalStorage
localStorage.setItem('username', 'john_doe');
const username = localStorage.getItem('username');
console.log('Stored username:', username);
// Example: Using SessionStorage
sessionStorage.setItem('token', 'abc123');
const token = sessionStorage.getItem('token');
console.log('Stored token:', token);
```
## Putting It All Together: Building a Weather App
Now, let's apply what we've learned to build a simple Weather App using a public weather API.
**Step-by-step project guide**
**Step 1: **Setup HTML Structure
Create an HTML file (index.html) with basic structure.
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Weather App</title>
</head>
<body>
<h1>Weather App</h1>
<div id="weather-info"></div>
<script src="script.js"></script>
</body>
</html>
```
**Step 2:** Create JavaScript file (script.js)
```
// script.js
const apiKey = 'your_api_key'; // Replace with your API key
const apiUrl = `https://api.openweathermap.org/data/2.5/weather?q=London&appid=${apiKey}`;
const weatherInfo = document.getElementById('weather-info');
fetch(apiUrl)
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.json();
})
.then(data => {
const { name, weather, main } = data;
const description = weather[0].description;
const temperature = main.temp;
weatherInfo.innerHTML = `
<h2>${name}</h2>
<p>Weather: ${description}</p>
<p>Temperature: ${temperature} K</p>
`;
})
.catch(error => {
console.error('Error fetching weather data:', error);
weatherInfo.textContent = 'Failed to fetch weather data';
});
```
Implement the JavaScript logic to fetch weather data and update the UI.
**Step 3: **Get an API Key
Sign up on a weather API provider (e.g., OpenWeatherMap) to obtain an API key.
**Step 4:** Test Your App
Open _index.html_ in a web browser and see the weather information displayed.
## Best Practices and Tips
When working with Web APIs, it's important to follow best practices to ensure security, efficiency, and reliability.
**Error handling best practices:** Always handle errors gracefully using try/catch or _.catch()_ method.
**Security considerations:** Use HTTPS for secure data transmission. Avoid exposing sensitive information in URLs.
**Cross-Origin Resource Sharing (CORS):** Understand and handle CORS restrictions when making requests to APIs hosted on different domains.
## Conclusion
In this tutorial, we've covered the basics of Web APIs and how to use them with JavaScript. We started with an introduction to Fetch API, explored sending data with POST requests, and learned about asynchronous programming with Promises and async/await. We also introduced other Web APIs like _Geolocation_, _LocalStorage_, and _SessionStorage_. Finally, we built a simple Weather App to apply what we've learned. Please ask questions, I will answer them all.

1,922,393 | self vs Self in Swift Programming | In Swift, self and Self (with a capital 'S') play distinct roles in object-oriented and... | 0 | 2024-07-13T15:26:29 | https://dev.to/vinaykumar0339/self-vs-self-in-swift-programming-fhg | swift, ios | In Swift, `self` and `Self` (with a capital 'S') play distinct roles in object-oriented and protocol-oriented programming. They are crucial keywords that ensure clarity, type safety, and facilitate various coding patterns. Let’s dive into their meanings, differences, and practical applications
## self
`self` refers to a class or struct's current instance (object). It distinguishes instance variables or methods from local variables or parameters.
## Self
`Self` (with a capital 'S') refers to the current type itself. It is beneficial in protocols and generic contexts to ensure type safety and clarity.
## Example
```swift
class Person {
private var name: String
private var age: Int
init(name: String, age: Int) {
self.name = name
self.age = age
}
func updateAgeWithExactClassType(age: Int) -> Person {
self.age = age
return self
}
func updateAgeWithSelfKeyword(age: Int) -> Self {
self.age = age
return self
}
}
let person = Person(name: "vinay", age: 26)
person.updateAgeWithExactClassType(age: 30)
person.updateAgeWithSelfKeyword(age: 40)
```
1. In the `Person` class example above, `self` is used to refer to the current instance of the class when accessing its properties or methods. Which uses to differ method parameters from instance variables
2. The `updateAgeWithSelfKeyword` method uses `Self` as its return type. This allows the method to return an instance of the same class type (`Person`) or its subclass dynamically, which is useful for method chaining and adhering to the builder pattern
## Benefits of `Self` over exact Class `Person` as return type
### Drawbacks of `updateAgeWithExactClassType`
The `updateAgeWithExactClassType` method explicitly returns `Person`, which limits its usage when subclassing `Person`. If you subclass `Person`, you cannot override this method to return instances of the subclass without changing its return type.
### Advantages of `updateAgeWithSelfKeyword`
The `updateAgeWithSelfKeyword` method uses `Self` as its return type. This means it dynamically resolves to the type of the current instance (`Person` or its subclass). You can override this method in subclasses and have it return instances of those subclasses, maintaining type safety and adhering to the builder pattern.
To understand more let's change the code snippet a little bit.
```swift
class AdvancedPerson: Person {
func extraFunctionality() {
print("person has super power like avengers")
}
override func updateAgeWithExactClassType(age: Int) -> Person {
// some code
return self
}
override func updateAgeWithSelfKeyword(age: Int) -> Self {
// some code
return self
}
}
let advancedPerson = AdvancedPerson(name: "IronMan", age: 40)
advancedPerson.updateAgeWithExactClassType(age: 50)
advancedPerson.updateAgeWithSelfKeyword(age: 50)
```
* `updateAgeWithExactClassType` returns `Person` as a type which won't have functionalities of the sub-class `AdvancedPerson` we can't be chaining to access methods of the `AdvancedPerson` class.
* `updateAgeWithSelfKeyword` returns `Self` on runtime Swift knows what type should return so that we can access existing functionalities of the sub-class `AdvancedPerson`
## Use of `Self` with protocols
```swift
protocol Address {
func addAddress(address: String) -> Self
}
class PersonWithAddress: Person, Address {
private var address: String?
func addAddress(address: String) -> Self {
self.address = address
return self
}
}
let personWithAddress = PersonWithAddress(name: "vinay", age: 26)
personWithAddress.addAddress(address: "India")
```
## Benefits
### self
* **Clarity:** Helps distinguish between instance properties and local variables or parameters within methods.
* **Avoiding Name Conflicts:** Ensures clear referencing of instance properties and methods.
### Self
* **Type Safety:** Guarantees that protocols and generics return or reference the exact type of the conforming or implementing instance.
* **Flexibility:** Supports method chaining and builder pattern, improving code readability and maintainability. Using `Self` allows for returning the exact type without explicitly specifying it, promoting easier code maintenance and adaptation.
## Conclusion
Understanding the distinctions between `self` and `Self` is crucial for writing clear, type-safe, and maintainable Swift code. While `self` refers to the current instance, `Self` ensures consistency in types within protocols and generics. Leveraging these keywords effectively enhances your ability to design robust Swift solutions.
> `self` -> Refers to the current instance (object).
> `Self` -> Refers to the type itself, ensuring type safety and clarity. It simplifies method chaining and conforms to protocols in a flexible manner, improving code maintainability.

1,922,258 | Docker Advanced Concepts - Docker Compose and Docker Swarm: Day 6 of 50 days DevOps Tools Series | Introduction Welcome to Day 6 of our 50 Days DevOps Tools series. In the previous post, we... | 0 | 2024-07-13T12:48:22 | https://dev.to/shivam_agnihotri/docker-advanced-concepts-docker-compose-and-docker-swarm-day-6-of-50-days-devops-tools-series-1kn | docker, devops, beginners, automation | ## **Introduction**
Welcome to Day 6 of our 50 Days DevOps Tools series. In the previous post, we covered the basics of Docker, including its architecture and essential commands. Today, we will delve into more advanced Docker concepts: Docker Compose and Docker Swarm. These tools help manage multi-container applications and orchestrate container deployments at scale.
**Docker Compose**
Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services, networks, and volumes. Then, with a single command, you create and start all the services from your configuration.
**Why Docker Compose?**
**Multi-Container Deployment:** Easily manage multiple containers that make up your application.
**Configuration Management:** Define the entire configuration in a single docker-compose.yml file.
**Simplified Workflow:** Start and stop your application with a single command.
**Consistency:** Ensure that the environment is consistent across development, testing, and production.
**Key Concepts:**
**Service:** A service defines a container that runs a specific image.
**Network:** Networks allow containers to communicate with each other.
**Volume:** Volumes persist data generated by containers.
Basic Commands
**docker-compose up:** Create and start containers defined in docker-compose.yml.
**docker-compose down:** Stop and remove containers, networks, and volumes defined in docker-compose.yml.
```
version: '3.9'
services:
web:
image: nginx
ports:
- "80:80"
app:
image: myapp
depends_on:
- db
db:
image: postgres
environment:
POSTGRES_PASSWORD: example
```
**Explanation:**
**version:** Specifies the Compose file format version.
**services:** Defines the services that make up your application.
**web:** A service that uses the nginx image and maps port 80 of the container to port 80 of the host.
**app:** A service that uses the myapp image and depends on the db service.
**db:** A service that uses the postgres image and sets an environment variable for the database password.
**Running the Application**
**Start the services:** Run docker-compose up in the directory containing the docker-compose.yml file.
**Stop the services:** Run docker-compose down to stop and remove the containers.
## **Docker Swarm**
Docker Swarm is Docker’s native clustering and orchestration tool. It allows you to create and manage a cluster of Docker nodes as a single virtual system. Docker Swarm enables you to deploy and manage containers across multiple host machines.
**Why Docker Swarm?**
**Scalability:** Easily scale your application up or down by adding or removing nodes.
**High Availability:** Ensure that your application remains available even if some nodes fail.
**Load Balancing:** Distribute traffic evenly across all running instances of a service.
**Service Discovery:** Automatically discover and connect services within the swarm.
**Key Concepts**
**Node:** An individual Docker engine participating in the swarm.
**Service:** A definition of the tasks to be executed across the swarm.
**Task:** A single instance of a running container.
**Manager Node:** Manages the swarm and orchestrates tasks.
**Worker Node:** Executes tasks assigned by the manager node.
**Basic Commands**
docker swarm init: Initialize a new swarm.
docker swarm join: Join a node to an existing swarm.
docker service create: Create a new service.
docker service ls: List all services in the swarm.
docker service scale: Scale a service to a specified number of replicas.
docker node ls: List all nodes in the swarm.
**Example Swarm Setup**
Initialize the Swarm
```
docker swarm init --advertise-addr <MANAGER-IP>
```
Add Worker Nodes
```
docker swarm join --token <SWARM-TOKEN> <MANAGER-IP>:2377
```
Deploy a service
```
docker service create --name web --replicas 3 -p 80:80 nginx
```
Scale the service
```
docker service scale web=5
```
**Explanation**
**Initialize the Swarm:** The manager node initializes the swarm and specifies the IP address to advertise to other nodes.
**Add Worker Nodes:** Worker nodes join the swarm using the token and manager IP address.
**Deploy a Service:** Creates a service named web with 3 replicas and publishes port 80.
**Scale the Service:** Scales the web service to 5 replicas.
**Conclusion**
Docker Compose and Docker Swarm are powerful tools that extend Docker’s capabilities for managing multi-container applications and orchestrating deployments at scale. Docker Compose simplifies the development and testing workflow by managing multi-container applications with a single configuration file. Docker Swarm enables scalable, high-availability deployments across multiple hosts.

I have defined few profiles in my springboot app. One of them is 'localtest'. All profiles contain some common properties.
I run app as:
mvn spring-boot:run -Dspring.profiles.active=localtest
My expectation is that common properties have values picked up from profile 'localtest'. But I observe thats not the case.
For eg. port in 'localtest' is 8081, but application is instead available on port 8089 which is defined in some other profile.
What am I missing in my understanding of profiles? | mghildiy |
