But what exactly is digital transformation, and what benefits does it bring to businesses? This article explores the multifaceted advantages of digital transformation, shedding light on how it can revolutionize various aspects of an organization.
Understanding digital transformation
------------------------------------
Digital transformation involves integrating digital technologies into all areas of a business, fundamentally changing how it operates and delivers value to customers. This process goes beyond merely adopting new technologies; it requires a cultural shift that encourages innovation, embraces change, and continually challenges the status quo.
Key Benefits of Digital Transformation
--------------------------------------
### 1\. Enhanced Operational Efficiency
Digital transformation streamlines business processes, reducing the time and effort required to complete tasks. Automation plays a significant role here, as it eliminates manual, repetitive tasks and frees up employees to focus on more strategic activities. For instance, robotic process automation (RPA) can handle data entry, invoicing, and other routine tasks, significantly improving efficiency.
According to [Virtru](https://www.virtru.com/blog/8-benefits-digital-transformation), companies that embrace digital transformation see marked improvements in operational efficiency, leading to cost savings and enhanced productivity.
### 2\. An improved customer experience
At the heart of digital transformation is the goal of enhancing the customer experience. By leveraging digital tools and data analytics, businesses can gain deeper insights into customer preferences and behaviors, allowing them to deliver personalized and engaging experiences. For example, customer relationship management (CRM) systems help businesses understand customer needs and tailor their interactions accordingly.
[Quixy](https://quixy.com/blog/top-benefits-of-digital-transformation/) highlights that a superior customer experience leads to increased customer loyalty and retention, ultimately driving business growth.
### 3\. Data-Driven Decision Making
Digital transformation enables businesses to harness the power of data. With advanced analytics and big data technologies, organizations can collect, process, and analyze vast amounts of data in real time. This data-driven approach allows for more informed decision-making, helping businesses identify trends, optimize operations, and predict future outcomes.
As [Trustpair](https://trustpair.com/blog/what-are-the-benefits-of-digital-transformation/) points out, data-driven decision-making enhances agility and responsiveness, enabling businesses to adapt quickly to changing market conditions.
### 4\. Increased Agility and Innovation
In a competitive market, the ability to innovate quickly is crucial. Digital transformation fosters a culture of agility and continuous improvement, encouraging businesses to experiment with new ideas and technologies. Agile methodologies and digital tools facilitate rapid prototyping, iterative development, and swift feedback loops, accelerating the innovation process.
[PTC](https://www.ptc.com/en/blogs/corporate/digital-transformation-benefits) emphasizes that digital transformation helps businesses stay ahead of the curve by continuously evolving and embracing new opportunities.
### 5\. Enhanced Collaboration and Communication
Digital transformation breaks down silos within organizations, promoting better collaboration and communication among teams. Cloud-based tools, collaboration platforms, and digital workspaces enable employees to work together seamlessly, regardless of their physical location. This interconnected environment fosters teamwork, knowledge sharing, and collective problem-solving.
[Thales Group](https://cpl.thalesgroup.com/software-monetization/benefits-of-digital-transformation) notes that improved collaboration and communication lead to higher employee engagement and productivity, driving overall business performance.
### 6\. Improved resource management
Digital transformation provides businesses with tools to manage resources more effectively. Enterprise Resource Planning (ERP) systems, for example, integrate various business processes into a single platform, offering real-time visibility into operations. This integration helps optimize resource allocation, reduce waste, and improve overall efficiency.
Businesses can ensure optimal resource use, leading to cost savings and improved operational performance, by leveraging digital technologies.
### 7\. Competitive advantage
Incorporating digital transformation into business strategy provides a significant competitive edge. Companies that effectively utilize digital technologies can respond faster to market changes, offer superior customer experiences, and innovate more rapidly than their competitors. This agility and responsiveness position them as leaders in their industries.
According to [Virtru](https://www.virtru.com/blog/8-benefits-digital-transformation), businesses that embrace digital transformation are better equipped to navigate disruptions and capitalize on new opportunities, ensuring long-term success.
### 8\. Increased Revenue and Growth
Ultimately, the benefits of digital transformation translate into increased revenue and business growth. By enhancing efficiency, improving the customer experience, and fostering innovation, businesses can drive higher sales and expand their market reach. Digital transformation opens up new revenue streams, such as online sales channels, subscription models, and digital services.
[Quixy](https://quixy.com/blog/top-benefits-of-digital-transformation/) highlights that businesses that successfully undergo digital transformation often see substantial improvements in their financial performance.
Real-World Examples of Digital Transformation Success
-----------------------------------------------------
### 1\. General Electric (GE)
General Electric embarked on a digital transformation journey to become a leader in the Industrial Internet of Things (IIoT). By integrating digital technologies into its operations, GE created Predix, an industrial IoT platform that collects and analyzes data from industrial machines. This transformation enabled GE to offer predictive maintenance services, reducing downtime and operational costs for its customers.
### 2\. Starbucks
Starbucks leveraged digital transformation to enhance its customer experience through its mobile app and loyalty program. The app allows customers to order and pay ahead, earn rewards, and receive personalized offers. This digital initiative not only improved customer convenience but also provided Starbucks with valuable data to tailor its marketing strategies and drive customer engagement.
### 3\. Netflix
Netflix’s shift from a DVD rental service to a leading streaming platform is a prime example of digital transformation. By embracing digital technology, Netflix developed a robust streaming infrastructure and used data analytics to understand viewer preferences. This transformation allowed Netflix to deliver personalized content recommendations and create original programming that resonates with its audience.
Best Practices for Implementing Digital Transformation
------------------------------------------------------
### 1\. Develop a clear strategy.
A successful digital transformation begins with a well-defined strategy. Outline your objectives, identify key areas for improvement, and develop a roadmap for implementation. This strategic approach ensures that digital initiatives align with business goals and deliver measurable results.
### 2\. Foster a Culture of Innovation
Encourage a culture that embraces change and innovation. Provide employees with the tools and training they need to leverage digital technologies effectively. Encourage experimentation and view failure as a learning opportunity.
### 3\. Invest in the right technologies.
Choosing the right technologies is crucial for a successful digital transformation. Assess your business needs and invest in solutions that offer scalability, flexibility, and security. Cloud computing, AI, machine learning, and IoT are some of the technologies that can drive significant transformation.
### 4\. Focus on the customer experience
Put the customer at the forefront of your digital transformation efforts. Use data analytics to gain insights into customer behavior and preferences. Develop personalized experiences that meet customer needs and exceed their expectations.

I am looking for some honest views here.
Am deciding whether to start a level 5 course offered by Code Institute to get into tech in general, specifically full stack development at the age of 50!
Is it possible to get into tech, ie, full stack development or other areas of tech following on from this, such as aws, at 50 years of age?
Code Institute, perhaps unsurprisingly say age is no barrier, that it is irrelevant, however, is this really the case?
Would really appreciate any views on this. Is it possible to start a career in tech, in the areas mentioned at this age? Is there still scope for development? Without sounding crass, can you go on to earn the really good wages we hear about?
Should mention also, Bristol, UK, is the area, there are a lot of tech jobs here. Still, would very much appreciate any views people have on this.
Many thanks,
Kind regs,

1,867,531 | 🌈 2 Colors Extensions to make Visual Studio Code even better! | Colors 🌈 help us identify things in our surroundings, including Visual Studio Code instances and... | 20,133 | 2024-05-28T11:09:48 | https://leonardomontini.dev/vscode-folder-path-color-peacock/ | vscode, programming, productivity | Colors 🌈 help us identify things in our surroundings, including Visual Studio Code instances **and** files.
Today I show how I solved two problems I had, thanks to colors and 2 vscode extensions. Here's a video where I showcase them and how you can push the extension even further to get even better customization 👇
{% youtube bvaSo3tip2g %}
## 1. Identify different vscode instances
This is quite common, you may have a backend and a frontend repo, or simply you’re working on multiple projects and it happens that you have two or more vscode instances open.
Short answer: Peacock ([get the extension](https://marketplace.visualstudio.com/items?itemName=johnpapa.vscode-peacock))
It's quite a famous and widely used extension, but if you don’t know it yet, it's maybe time to give it a try!
(you can also customize projects from the settings, manually, but this extension makes it so much easier)
### Peacock Features
Some features you may find useful:
With the command `Peacock: Surprise me with a random color`, you can assign a random color to the current project. Try it if you dare!
If you have already a color in mind, you can set it with `Peacock: Enter a color`.
You're also covered if you want some suggestions, with `Peacock: Change to a Favorite Color` you'll get a list of predefined colors (you can also expand this list with your own colors).
## 2. Identify files and folders in the same repo
I was recently playing around with Module Federation, but this applies pretty much in all monorepo scenarios.
I wanted an easy way to know what project a file refers to and with another extension, Folder Path Color ([get the extension](https://marketplace.visualstudio.com/items?itemName=VisbyDev.folder-path-color)), I was able to do that!
It has some limitations since colors on filenames are already used to track git status, so it's up to you if you want to enable it or not.
### Folder Path Color Features
The core feature here is that you can customize the colors for your file based on their path. You can also assign a symbol.
This is the config I use in the video:
```json
{
"folder-path-color.folders": [
{
"path": "host",
"symbol": "H",
"tooltip": "Host"
},
{
"path": "app01",
"symbol": "01",
"tooltip": "App 01",
"color": "blue"
},
{
"path": "app02",
"symbol": "02",
"tooltip": "App 02",
"color": "cyan"
}
]
}
```
The symbol (that is a string) is particularly useful to overcome the limitation of the colors on filenames, so that git can color your newly added file in green but you still have the symbol next to the filename to identify the project.
You have some default colors, but you can also expand them with a set of custom colors.
### Conclusion
This was a quick one, but I wanted to mention these two extensions I found to solve a couple of problems I had. Peacock is quite famous, but Folder Path Color is less known and I think it has some usecases.
If you want to see me testing the two extensions and their customization, here's the video: https://www.youtube.com/watch?v=bvaSo3tip2g

_For more content like this **[subscribe to the ShiftMag newsletter](https://shiftmag.dev/newsletter/)**._
Many things pass for AI, and sometimes it’s hard to put them under the common denominator, but Christine Spang still gives it a shot with a simple equation in her [Shift Miami talk](https://shift.infobip.com/us/): _Chatbots are cool, but what else can generative AI do_?
**Leverage = having a higher impact with a smaller input**
**AI = using computers to generate leverage**
**Computing** itself, argues Christine, **is about giving more leverage to individuals or groups,** and the rise of LLMs has driven AI magic into new sets of use cases.
> We used to carry water to the village; now we have tap water. We invented language, and then systems for storing information. We keep making better ways to use the data and information we have today – AI is our latest attempt at that.
## **Chatbots, knowledge bases, coding assistants**
Today, the most notable use cases are user-facing chatbots, knowledge bases, and coding assistants (or, as often happens, some combination of the three).
Chatbots have come a long way from their initial instances and can now boast **great UI and conversational intelligence. **
Christine argues that coding assistance **(or copilots) supercharges our coding powers**, ensuring enhanced productivity and efficiency in the dev cycle.
AI-powered knowledge bases give us **access to the right information at the time when we need it** , not when a customer service agent is available or can schedule a call.
As a good example of that (and the benefits that AI brings), Christine mentioned her company’s own chatbot, [Nylas Assist](https://nylas.com/blog/pr/nylas-launches-its-new-generative-ai-assist-chatbot/), a chat user interface for their docs. Launched in August 2023, **it has reduced the number of raised tickets by 25%** , even though the user base grew by 30% – that’s precisely the leverage she’s talking about
## Language is messy; data should not be
All three use cases are pretty useful – but is this the peak AI we’re experiencing? We’ve probably all guessed that it’s not. At the moment, Christine notes, **we have generalized datasets, which only allow us to get generalized actions. **
Human language, on the other hand, is messy, full of nuances, and context-dependent. Communication is the bottleneck where most relevant information and context pass through, she states, and communication happens over many different channels, like messaging apps, email, voice, and social media, as well asynchronously.
Current LLMs are trained on the entire scrapable content available online. That’s a lot of text but not necessarily a lot of (right) context. LLMS trained on social media, Christine exemplifies, don’t necessarily have the right context for business.
## Customization is the next step forward
Communication data is a haystack, she stresses, it’s not valuable as an unstructured pile.
Take, for example, email, which is Nylas’s bread–and–butter data. It is particularly messy, with plain text, images, links, and formatting. Passing that data to a model the right way is a challenge. Everything needs to be pre-processed in a specific way, **extracting not just information but also information order.** It needs to be structured to have value and the right context to move from generalized outputs.
Context is exactly how Christine sees generative AI evolving and generating even more leverage: When we access the context of a dataset rather than just the dataset itself, we can customize models and get customized actions instead of generalized ones.

This blog post makes a deep dive into TypeScript's object type system, exploring **interfaces** and **types**, difference between them with various examples to help you master these types.
_Originally published at_ [_https://antondevtips.com_](https://antondevtips.com/blog/typescript-interfaces-vs-types-understanding-the-difference)_._
## What Are Interfaces and Types In TypeScript
**Interfaces** and **types** belong to the [**object types**](https://antondevtips.com/blog/the-complete-guide-to-typescript-types) in TypeScript.
**Object types** in TypeScript groups a set of properties under a single type.
Object types can be defined either using `type` alias:
```typescript
type User = {
name: string;
age: number;
email: string;
};
const user: User = {
name: "Anton",
age: 30,
email: "info@antondevtips.com"
};
```
Or `interface` keyword:
```typescript
interface User {
name: string;
age: number;
email: string;
}
const user: User = {
name: "Anton",
age: 30,
email: "info@antondevtips.com"
};
```
## Interfaces in TypeScript
**Interfaces** are extendable and can inherit from other interfaces using the `extends` keyword:
```typescript
interface Employee extends User {
employeeId: number;
salary: number;
}
const employee: Employee = {
name: "Jack Sparrow",
age: 40,
email: "captain.jack@gmail.com",
employeeId: 1,
salary: 2000
};
```
> **Classes** in TypeScript can inherit from interfaces and implement them using the `extends` keyword.
You can also extend **interfaces** by declaring the same interface multiple times:
```typescript
interface User {
name: string;
age: number;
email: string;
}
interface User {
phone: string;
}
const user: User = {
name: "Anton",
age: 30,
email: "info@antondevtips.com",
phone: "1234567890"
};
```
In TypeScript interfaces, you can use property modifiers to define **optional** and **readonly** properties.
### Optional Properties
These properties are not mandatory when creating an object:
```typescript
interface User {
name: string;
age: number;
email?: string; // Optional property
}
const user: User = {
name: "Anton",
age: 30
};
```
### Readonly Properties
These properties cannot be modified after the object is created:
```typescript
interface User {
name: string;
readonly age: number;
email: string;
}
const user: User = {
name: "Anton",
age: 30,
email: "john.doe@example.com"
};
// Error: Cannot assign to 'age' because it is a read-only property.
// user.age = 31;
```
### Index Signatures
Index signatures allow you to define the type of keys and values that an object can have.
Sometimes you may not know all the names of the properties during compile time, but you do know the shape of the values.
In such use cases you can use an index signature to define the properties:
```typescript
interface Names {
[index: number]: string;
}
const names: Names = ["Anton", "Jack"];
```
You can also define dictionaries by using index signatures:
```typescript
interface NameDictionary {
[key: string]: string;
}
const dictionary: NameDictionary = {
name: "Anton",
email: "info@antondevtips.com"
};
```
There is a limitation when working with index signatures: you can't have named properties of another type:
```typescript
interface NumberDictionary {
[index: string]: number;
length: number;
// Error: Property 'name' of type 'string' is not assignable to 'string' index type 'number'.
name: string;
}
```
You can bypass this limitation my using Unions:
```typescript
interface Dictionary {
[index: string]: number | string;
length: number;
name: string;
}
const dictionary: Dictionary = {
name: "Anton",
email: "info@antondevtips.com",
length: 5
};
```
It might be useful to make index signatures readonly to prevent assignment to their indexes:
```typescript
interface ReadonlyDictionary {
readonly [index: number]: string;
}
const dictionary: ReadonlyDictionary = {
0: "Anton"
};
dictionary[0] = "John";
// Error: Index signature in type 'ReadonlyDictionary' is readonly.
```
## Types in TypeScript
The **type** in TypeScript is similar to the interfaces but you can't extend existing types or add new properties to them.
```typescript
type User = {
name: string;
age: number;
email: string;
};
type User = {
phone: string;
};
// Error: Duplicate identifier 'User'.
```
## Combining Interfaces and Types with Intersection Types
**Intersection types** in TypeScript allow you to combine multiple types into one.
An **intersection type** can be created by combining multiple interfaces or types using `&` operator:
```typescript
interface Person {
name: string;
}
interface ContactDetails {
email: string;
phone: string;
}
type Customer = Person & ContactDetails;
const customer: Customer = {
name: "Anton",
email: "info@antondevtips.com",
phone: "1234567890"
};
```
In these examples a `Customer` type is an **intersection type** that combines all properties from `Person` and `ContactDetails` interfaces.
It's important to note that you can only declare an **Intersection Type** with a **type** keyword.
You can't declare an interface type that holds an Intersection.
Intersections are not limited just to interfaces and types, they can be used with other types, including primitives, unions, and other intersections.
## Combining Interfaces and Types with Union Types
**Union type** in TypeScript is a type that is formed from two or more other types.
Union types are also called [**Discriminated Unions**](https://antondevtips.com/blog/mastering-discriminated-unions-in-typescript).
A variable of **union type** can have one of the types from the union.
Let's explore an example of geometrics shapes, that have common and different properties:
```typescript
interface Circle {
type: "circle";
radius: number;
}
interface Square {
type: "square";
square: string;
}
type Shape = Circle | Square;
```
Let's create a function that calculates a square for each shape:
```typescript
function getSquare(shape: Shape) {
if (shape.type === "circle") {
return Math.PI * shape.radius * shape.radius;
}
if (shape.type === "square") {
return shape.square;
}
}
const circle: Circle = {
type: "circle",
radius: 10
};
const square: Square = {
type: "square",
size: 5
};
console.log("Circle square: ", getSquare(circle));
console.log("Circle square: ", getSquare(square));
```
Here a `getSquare` function accepts a shape parameter that can be one of 2 types: `Circle` or `Square`.
We need to define a property that will allow to distinguish types from each other.
In our example it's a `type` property.
It's important to note that you can only create a **Union Type** with a **type** keyword.
You can't declare an interface type that holds a Union Type.
## Difference Between Interfaces and Types
**Interfaces:**
* can inherit from other interfaces
* can merge declarations, which is useful for extending existing objects
* can't represent more complex structures, like unions and intersections
**Types:**
* doesn't support inheritance
* doesn't allow extending existing objects
* can represent more complex structures, like unions and intersections
## Summary
Both **Interfaces** and **Types** in TypeScript are quite the same but have some differences.
Interfaces allow extension of existing objects, while types - not.
On the other hand Types can represent unions and intersections.
Use **Interfaces** when you need to define the structure of an object and take advantage of declaration merging and extension.
Use **Types** when you need you don't need them to be extended or to define complex types, such as unions or intersections.
There is no right choice whether to prefer Interfaces to Types or vice versa.
You can choose based on the needs and personal preference, the most important part is to select a single approach that will be consistent in the project.
My personal choice is **Types** as they can't be accidentally re-declared and extended, unless I need to do some fancy object-oriented stuff with interfaces and classes.
**P.S.:** you can find an amazing Cheat Sheets on [**Types**](https://www.typescriptlang.org/static/TypeScript%20Types-ae199d69aeecf7d4a2704a528d0fd3f9.png) and [**Interfaces**](https://www.typescriptlang.org/static/TypeScript%20Interfaces-34f1ad12132fb463bd1dfe5b85c5b2e6.png) from the Official TypeScript website.
Hope you find this blog post useful. Happy coding!

1,867,526 | C++: freeing resources in destructors using helper functions | In this article, we'll look at how to correctly destroy objects in the OOP-based C++ program without... | 0 | 2024-05-28T11:03:18 | https://dev.to/anogneva/c-freeing-resources-in-destructors-using-helper-functions-1f3d | cpp, programming, gamedev | In this article, we'll look at how to correctly destroy objects in the OOP\-based C\+\+ program without redundant operations\. This is the final article in the series about the bugs in qdEngine\.
## Failed resource release in qdEngine code
Here's a list of previous articles about checking the qdEngine game engine:
1. [Let's check the qdEngine game engine, part one: top 10 warnings issued by PVS\-Studio](https://pvs-studio.com/en/blog/posts/cpp/1119/)
1. [Let's check the qdEngine game engine, part two: simplifying C\+\+ code](https://pvs-studio.com/en/blog/posts/cpp/1121/)
1. [Let's check the qdEngine game engine, part three: 10 more bugs](https://pvs-studio.com/en/blog/posts/cpp/1123/)
Once I wrote them, I still had one more interesting PVS\-Studio warning\. So, I decided to make a separate article for this\. Here's the warning:
[V1053](https://pvs-studio.com/en/docs/warnings/v1053/) \[[CERT\-OOP50\-CPP](https://wiki.sei.cmu.edu/confluence/display/cplusplus/OOP50-CPP.+Do+not+invoke+virtual+functions+from+constructors+or+destructors)\] Calling the 'Finit' virtual function in the destructor may lead to unexpected result at runtime\. gr\_dispatcher\.cpp 54
We can call virtual functions in destructors, and the C\+\+ standard clearly describes how this works\. Unfortunately, such code is a magnet for errors, that's why many coding standards and analyzers recommend against using these calls\. I once wrote an article on this topic: "[Virtual function calls in constructors and destructors \(C\+\+\)](https://pvs-studio.com/en/blog/posts/cpp/0891/)"\. If you're a beginner in C\+\+ or want to refresh your memory, I suggest taking a peek at it before you continue reading\. I also encourage you to read it if you're not sure what we're talking about\.
The code fragment related to the warning is quite large, but you can safely skip it\. We'll break it down below using some synthetic examples\.
<spoiler title="The qdEngine code.">
The *Finit* function is called in the base class destructor\. Since the *DDraw\_grDispatcher* subclass has already been destroyed, its *Finit* function isn't called\.
```cpp
class grDispatcher
{
....
virtual ~grDispatcher();
virtual bool Finit();
....
};
grDispatcher::~grDispatcher()
{
Finit();
if (dispatcher_ptr_ == this) dispatcher_ptr_ = 0;
}
bool grDispatcher::Finit()
{
#ifdef _GR_ENABLE_ZBUFFER
free_zbuffer();
#endif
flags &= ~GR_INITED;
SizeX = SizeY = 0;
wndPosX = wndPosY = 0;
screenBuf = NULL;
delete yTable;
yTable = NULL;
return true;
}
class DDraw_grDispatcher : public grDispatcher
{
....
~DDraw_grDispatcher();
bool Finit();
....
};
DDraw_grDispatcher::~DDraw_grDispatcher()
{
if (ddobj_)
{
ddobj_ -> Release();
ddobj_ = NULL;
}
video_modes_.clear();
}
bool DDraw_grDispatcher::Finit()
{
grDispatcher::Finit();
if (back_surface_)
{
while(
back_surface_ -> GetBltStatus(DDGBS_ISBLTDONE) == DDERR_WASSTILLDRAWING);
back_surface_ -> Unlock(&back_surface_obj_);
ddobj_ -> SetCooperativeLevel((HWND)Get_hWnd(),DDSCL_NORMAL);
if (fullscreen_ && ddobj_) ddobj_ -> RestoreDisplayMode();
}
if (prim_surface_)
{
prim_surface_ -> Release();
prim_surface_ = NULL;
}
if (back_surface_)
{
back_surface_ -> Release();
back_surface_ = NULL;
}
return true;
}
```
</spoiler>
## Synthetic code example for error analysis
Now, let's figure out what the issue is\. We'll use the synthetic code and the [Compiler Explorer](https://godbolt.org/) website to quickly explore how the code works\.
We need to create a class hierarchy to manage some resources\. We'll also use the polymorphism principle to work with objects via a pointer to the base class\.
Let's start with the simplest base class:
```cpp
#include <memory>
#include <iostream>
class Resource
{
public:
void Create() {}
void Destroy() {}
};
class A
{
std::unique_ptr<Resource> m_a;
public:
void InitA()
{
m_a = std::make_unique<Resource>();
m_a->Create();
}
virtual ~A()
{
std::cout << "~A()" << std::endl;
if (m_a != nullptr)
m_a->Destroy();
}
};
int main()
{
std::unique_ptr<A> p = std::make_unique<A>();
return 0;
}
```
So far, everything seems OK\. We get the following output for the [online example](https://godbolt.org/z/z8EdqWv3n):
```cpp
~A()
```
Then we find out that the class state should be reset from time to time\. We need to release resources and rather than waiting for the destructor call when the class is destroyed\. Here's the design error: a virtual function is created to clean up the class\. A developer creates an additional virtual class interface like this:
```cpp
#include <memory>
#include <iostream>
class Resource
{
public:
void Create() {}
void Destroy() {}
};
class A
{
std::unique_ptr<Resource> m_a;
public:
void InitA()
{
m_a = std::make_unique<Resource>();
m_a->Create();
}
virtual void Reset()
{
std::cout << "A::Reset()" << std::endl;
if (m_a != nullptr)
{
m_a->Destroy();
m_a.reset();
}
}
virtual ~A()
{
std::cout << "~A()" << std::endl;
Reset();
}
};
int main()
{
std::unique_ptr<A> p = std::make_unique<A>();
return 0;
}
```
[The online example displays the following output](https://godbolt.org/z/hTs4YGGqc):
```cpp
~A()
A::Reset()
```
The virtual *Reset* function is added to free resources\. The destructor doesn't release resources to avoid the code duplication\. Now it just calls the function\.
So far, it seems like everything is still OK, but let's add the subclass:
```cpp
#include <memory>
#include <iostream>
class Resource
{
public:
void Create() {}
void Destroy() {}
};
class A
{
std::unique_ptr<Resource> m_a;
public:
void InitA()
{
m_a = std::make_unique<Resource>();
m_a->Create();
}
virtual void Reset()
{
std::cout << "A::Reset()" << std::endl;
if (m_a != nullptr)
{
m_a->Destroy();
m_a.reset();
}
}
virtual ~A()
{
std::cout << "~A()" << std::endl;
Reset();
}
};
class B : public A
{
std::unique_ptr<Resource> m_b;
public:
void InitB()
{
m_b = std::make_unique<Resource>();
m_b->Create();
}
void Reset()
{
std::cout << "B::Reset()" << std::endl;
if (m_b != nullptr)
{
m_b->Destroy();
m_b.reset();
}
A::Reset();
}
~B()
{
std::cout << "~B()" << std::endl;
Reset();
}
};
int main()
{
std::unique_ptr<A> p = std::make_unique<B>();
p->Reset();
std::cout << "------------" << std::endl;
p->InitA();
return 0;
}
```
[The online example displays the output](https://godbolt.org/z/rPzbdrfo1):
```cpp
B::Reset()
A::Reset()
------------
~B()
B::Reset()
A::Reset()
~A()
A::Reset()
```
If we explicitly call the *Reset* function from the external code, everything works fine\. The *B::Reset\(\)* function is called, and then it calls a function with the same name from the base class\.
There is an issue with the destructor\. Each destructor calls the *Reset* function\. It results in redundant operations because the *Reset* function calls its own version from the base class\.
If we continue this strange inheritance, we will make the issue worse and worse\. And it will cause more and more redundant function calls\.
Here's the [code output](https://godbolt.org/z/dnGKEr95r) where another class has been added:
```cpp
C::Reset()
B::Reset()
A::Reset()
------------
~C()
C::Reset()
B::Reset()
A::Reset()
~B()
B::Reset()
A::Reset()
~A()
A::Reset()
```
There's obviously a class design error\. But it's obvious to us now, though\. In a real project, such errors can thrive and remain unnoticed by the developer's eye: the code works and the *Reset* functions do their task\. But redundant and inefficient operations are still here\.
When a dev notices the described error and tries to fix it, they risk making two other typical errors\.
**The first option\.** They declare the *Reset* functions as non\-virtual and do not call the base \(*x::Reset*\) options in them\. Then, each destructor calls only the *Reset* function from its class and releases only its own resources\. This really takes away the redundancy in the operation of destructors\. However, when *Reset* is called externally, the cleanup of the object state breaks\. [The broken code displays](https://godbolt.org/z/TM9eqo4Pz):
```cpp
A::Reset() // Cleanup resources is broken externally
------------
~C()
C::Reset()
~B()
B::Reset()
~A()
A::Reset()
```
**The second option\.** They call the *Reset* virtual function once from the base class destructor\. This doesn't work because, according to C\+\+ rules, implementation of the *Reset* function from base class will be called, not from subclasses\. This makes sense because by the time the *~A\(\)* destructor is called, all subclasses have been destroyed, and functions can't be called from them\. [The broken code displays](https://godbolt.org/z/6cs9aj4aG):
```cpp
C::Reset()
B::Reset()
A::Reset()
------------
~C()
~B()
~A()
A::Reset() // Release resources only in the base class
```
It's this type of the error that we've found in the qdEngine project thanks to PVS\-Studio\. If you wish, now you can scroll up to the beginning of the article and see the corresponding code from the game engine\.
## Fixed synthetic code
So, how can we correctly use classes to avoid numerous redundant calls?
To do this, we need to separate the release of internal class resourses from the public interface\. It'd be better to create non\-virtual functions that are only responsible for releasing the data in classes where they're declared\. Let's name them *ResetImpl* and make private because they're not for the external use\.
Destructors will simply delegate their work to the *ResetImpl* functions\.
The *Reset* function will remain public and virtual\. It'll release data of all classes using the same *ResetImpl* helper functions\.
Let's put everything together and write correct code:
```cpp
#include <memory>
#include <iostream>
class Resource
{
public:
void Create() {}
void Destroy() {}
};
class A
{
std::unique_ptr<Resource> m_a;
void ResetImpl()
{
std::cout << "A::ResetImpl()" << std::endl;
if (m_a != nullptr)
{
m_a->Destroy();
m_a.reset();
}
}
public:
void InitA()
{
m_a = std::make_unique<Resource>();
m_a->Create();
}
virtual void Reset()
{
std::cout << "A::Reset()" << std::endl;
ResetImpl();
}
virtual ~A()
{
std::cout << "~A()" << std::endl;
ResetImpl();
}
};
class B : public A
{
std::unique_ptr<Resource> m_b;
void ResetImpl()
{
std::cout << "B::ResetImpl()" << std::endl;
if (m_b != nullptr)
{
m_b->Destroy();
m_b.reset();
}
}
public:
void InitB()
{
m_b = std::make_unique<Resource>();
m_b->Create();
}
virtual void Reset()
{
std::cout << "B::Reset()" << std::endl;
ResetImpl();
A::Reset();
}
virtual ~B()
{
std::cout << "~B()" << std::endl;
ResetImpl();
}
};
class C : public B
{
std::unique_ptr<Resource> m_c;
void ResetImpl()
{
std::cout << "C::ResetImpl()" << std::endl;
if (m_c != nullptr)
{
m_c->Destroy();
m_c.reset();
}
}
public:
void InitC()
{
m_c = std::make_unique<Resource>();
m_c->Create();
}
virtual void Reset()
{
std::cout << "C::Reset()" << std::endl;
ResetImpl();
B::Reset();
}
virtual ~C()
{
std::cout << "~C()" << std::endl;
ResetImpl();
}
};
int main()
{
std::unique_ptr<A> p = std::make_unique<C>();
p->Reset();
std::cout << "------------" << std::endl;
return 0;
}
```
[The online example displays](https://godbolt.org/z/G3ohvE6EY):
```cpp
C::Reset()
C::ResetImpl()
B::Reset()
B::ResetImpl()
A::Reset()
A::ResetImpl()
------------
~C()
C::ResetImpl()
~B()
B::ResetImpl()
~A()
A::ResetImpl()
```
I can't say the synthetic code looks nice\. However, it's full of As, Bs, and Cs, so it's very easy to make a typo\. Let's forgive the synthetic examples for this\. The code works, and we've deleted redundant operations\. That's a good result\.
## Conclusion
A virtual function call in a destructor isn't always an error\. However, this may be a sign of the poor class design\. The *qdEngine* project is a great example of such a case\.
The PVS\-Studio analyzer issues the [V1053](https://pvs-studio.com/en/docs/warnings/v1053/) warning if a virtual function is called in a constructor or destructor\. This is a good reason to take another look at the code and see if there's anything we can fix or refactor\. | anogneva |
1,867,525 | F# For Dummys - Day 16 Collections Sequence | Today we learn Sequence, represents an ordered, read-only series of elements Why... | 0 | 2024-05-28T11:01:54 | https://dev.to/pythonzhu/f-for-dummys-day-16-collections-sequence-can | fsharp | Today we learn Sequence, represents an ordered, read-only series of elements
#### Why Sequence
- Sequences are particularly useful when you have a large, ordered collection of data but do not necessarily expect to use all of the elements.
- Individual sequence elements are computed on-demand, so a sequence can provide better performance than a list in situations in which not all the elements are used</br>
**What is computed on-demand**</br>
like buying a burger in KFC, the staff prepared 1000 burgers in the early morning, so you got your burger immediately, all the burgers are made before customer order, this is called *eager evaluation*</br>
then you ordered a fried chicken, the staff replies: sorry, you have to wait for a minute, as we need to fry the chicken first, they only do the work when someone ordered, this is called *lazy evaluation*, also known as *On-demand computation*
#### Create Sequence
- Explicitly specifying elements
```f#
let seq1 = seq [1; 2; 3; 4]
printfn "seq: %A" seq1
```
- Using range expression
```f#
let seq1 = seq { 1 .. 10 } // from 1 to 10
printfn "seq: %A" seq1 // seq: seq [1; 2; 3; 4; ...]
```
use step in range expression
```f#
let seq1 = seq { 1 .. 2 .. 10 } // start from 1, add 2 each time
printfn "seq: %A" seq1 // seq: seq [1; 3; 5; 7; ...]
```
- Using for loop
```f#
let seq1 = seq { for i in 1 .. 10 -> i }
printfn "seq: %A" seq1
```
- ofList</br>
Views the given list as a sequence
```f#
let inputs = [ 1; 2; 5 ]
let seq1 = inputs |> Seq.ofList
printfn "seq: %A" seq1
```
- ofArray</br>
```f#
let inputs = [| 1; 2; 5 |]
let seq1 = inputs |> Seq.ofArray
printfn "seq: %A" seq1
```
- Seq.initInfinite
generate an infinite sequence
```f#
let infiniteSeq = Seq.initInfinite (fun i -> i * 2)
printfn "infiniteSeq %A" infiniteSeq
```
define a start for infinite sequence
```f#
let start = 5
let infiniteSeq = Seq.initInfinite (fun i -> i + start)
printfn "infiniteSeq %A" infiniteSeq // infiniteSeq seq [5; 6; 7; 8; ...]
```
or define a start like this
```f#
let infiniteSeq = Seq.initInfinite ((+) 5)
printfn "infiniteSeq %A" infiniteSeq // infiniteSeq seq [5; 6; 7; 8; ...]
```
#### Loop Sequence
- for loop
```f#
let numbers = seq { 1 .. 10 }
for number in numbers do
printfn "Number: %d" number
```
- Seq.iter
```f#
let numbers = seq { 1 .. 10 }
Seq.iter (fun x -> printfn "Number: %d" x) numbers
```
#### Access element
- Seq.item
syntax: Seq.item index source, thrown ArgumentException when the index is negative or the input sequence does not contain enough elements
```f#
let numbers = seq { 1 .. 10 }
let thirdElement = Seq.item 2 numbers // Indexing is zero-based
printfn "The third element is %d" thirdElement
```
- Seq.head && Seq.tail
Seq.head: Returns the first element of the sequence</br>
Seq.tail: Returns a sequence that skips 1 element of the underlying sequence and then yields the remaining elements of the sequence
```f#
let numbers = seq { 1 .. 10 }
let firstElement = Seq.head numbers
let restElement = Seq.tail numbers
printfn "The first element is %d" firstElement // The first element is 1
printfn "The rest element is %A" restElement // The rest element is seq [2; 3; 4; 5; ...]
```
#### Operate element
- Seq.updateAt
Return a new sequence with the item at a given index set to the new value</br>
syntax: Seq.updateAt index value source
```f#
let newSeq = Seq.updateAt 1 9 seq { 0; 1; 2 }
// let newSeq = Seq.updateAt 1 9 (seq { 0; 1; 2 })
printfn "newSeq: %A" newSeq // newSeq: seq [0; 9; 2]
```
- Seq.filter
Returns a new collection containing only the elements of the collection for which the given predicate returns "true". This is a synonym for Seq.where</br>
syntax: Seq.filter predicateFunc sourceSeq
```f#
let numbers = seq { 1 .. 10 }
let evenNumbers = Seq.filter (fun x -> x % 2 = 0) numbers
Seq.iter (fun x -> printfn "Even Number: %d" x) evenNumbers
```
- Seq.map
Builds a new collection whose elements are the results of applying the given function to each of the elements of the collection</br>
syntax: Seq.filter mappingFunc sourceSeq
```f#
let numbers = seq { 1 .. 10 }
let doubleNumbers = Seq.map (fun x -> x * 2) numbers
Seq.iter (fun x -> printfn "doubleNumbers: %d" x) doubleNumbers
```
- Seq.fold
Applies a function to each element of the collection
syntax: Seq.fold folderFunc state sourceSeq
```f#
type Charge =
| In of int
| Out of int
let inputs = [In 1; Out 2; In 3]
let balance = Seq.fold (fun acc charge ->
match charge with
| In i -> acc + i
| Out o -> acc - o) 0 inputs
printfn "balance %A" balance // balance 2
```
or use pipeline operator to pass state sourceSeq, here is ||> for passing more than one param
```f#
type Charge =
| In of int
| Out of int
let inputs = [In 1; Out 2; In 3]
let balance = (0, inputs) ||> Seq.fold (fun acc charge ->
match charge with
| In i -> acc + i
| Out o -> acc - o)
printfn "balance %A" balance // balance 2

Its robustness, versatility, and scalability make it a preferred choice for businesses looking to build reliable and efficient software solutions. But what exactly is Java application development for businesses, and why is it so important? This article delves into the fundamentals, benefits, and best practices of Java application development for businesses, providing a comprehensive understanding of its significance.
Understanding Java application development
------------------------------------------
Java application development is the process of using the Java programming language to create applications that meet specific business needs. Java's platform-independent nature, extensive libraries, and strong community support make it an ideal choice for developing a wide range of applications, from web and mobile applications to complex enterprise systems.

Additionally, Java's clear syntax and structure make the codebase easy to maintain and update, ensuring long-term viability and reducing maintenance costs.
### 4\. Security and Compliance
Security is a top priority for any business application, and Java delivers on this front. The language offers robust security features, including advanced authentication, cryptography, and access control mechanisms. Java's built-in security measures help protect applications from common vulnerabilities and ensure compliance with industry standards and regulations.
### 5\. Extensive community support
Java boasts one of the largest and most active developer communities in the world. This extensive support network provides businesses with access to a wealth of resources, including libraries, frameworks, and tools. Whether it's troubleshooting, learning new techniques, or finding ready-made solutions, the Java community offers invaluable assistance that accelerates development and problem-solving.
Best Practices for Java Application Development
-----------------------------------------------
### 1\. Define clear objectives and requirements.
Successful Java application development starts with a clear understanding of business objectives and requirements. Engage stakeholders to gather detailed requirements and define the scope of the project. This clarity ensures that the development process aligns with business goals and delivers the desired outcomes.

Use automated tools for continuous integration and continuous deployment (CI/CD), monitor application performance, and implement feedback loops to ensure rapid iteration and high-quality releases.
Real-World Examples of Java Application Development
---------------------------------------------------
### 1\. Banking and Financial Services
The banking and financial services industry widely uses Java due to its reliability and security features. For example, many financial institutions use Java to develop online banking platforms, payment gateways, and fraud detection systems. These applications handle millions of transactions daily and require robust security measures to protect sensitive financial data.
### 2\. E-Commerce Platforms
E-commerce giants like Amazon rely on Java for their backend systems. Java's scalability and performance capabilities make it ideal for handling the high traffic and complex transactions associated with e-commerce platforms. Custom Java applications support inventory management, order processing, and customer service, ensuring a seamless shopping experience.
### 3\. Healthcare Systems
In the healthcare sector, Java applications power electronic health records (EHR) systems, telemedicine platforms, and patient management systems. For instance, a healthcare provider might use Java to develop a custom EHR system that integrates patient records, appointment scheduling, and billing processes, enhancing efficiency and patient care.
### 4\. Enterprise Resource Planning (ERP)
Java is a popular choice for developing ERP systems that integrate various business processes, including finance, HR, and supply chain management. Companies like SAP and Oracle use Java to build comprehensive ERP solutions that provide real-time insights and streamline operations across the organization.
### 5\. Telecommunications
Telecommunications companies leverage Java to develop network management systems, customer service portals, and billing systems. Java's ability to handle concurrent connections and process large volumes of data in real-time makes it ideal for the telecommunications industry.
Conclusion

They don't replace a person's value but add to it. Our content creation team is an excellent example. We've used them to help improve our workflow. We've used checklists since the advent of the content team and have seen some success. We have gone through some twists and turns as we tried optimizing our checklists. We've learned about our workflow, developed better ways to optimize the flow, and redone the checklists.
We started our content team with a simple checklist. We have multiple moving parts as different people are responsible for separate sections. I am in charge of the task approvals, my writer creates the content, and another one of my employees is responsible for distributing them. This system has evolved as it worked for a short time. We've broken down tasks into smaller sections to divide tasks and responsibilities. We've become more productive and enhanced our task completion. It has made our tasks manageable, and we've met our deadlines. Our checklists have five different phases;
## Preparation
I oversee the approval and add vital points to the task description. My writer makes a task description detailing what the article will contain. Doing this has helped us narrow our objectives to keep our content direct. 
## Writing
Our writer handles the writing phase. He has a to-do list that guides him. My task is to check the written content and approve it when correct. I give out corrections where needed. 
## Deployment
The deployment phase is the next step of the process. Our writer handles this phase of the checklist. He deploys the articles and ensures all steps are covered. 
## Distribution Preparation
This phase has multiple people handling every section. Everyone completes their assigned task. They check the task once it's complete and assign the next person to take over. It has helped our time management and improved collaboration between our team members. 
## Distribute
One person handles our distribution section. We have multiple tasks highlighted in a template. It helps the entire productivity checklist and allows everyone to stay focused.
It has enhanced our workflow and has allowed us to achieve great things in our team.
## Creating Effective Checklists
You may get tempted to make checklists that work in all cases and scenarios. It is a bad idea that you shouldn't entertain. We used these three principles to help us create our checklists and increase our productivity.
## Keep checklist simple
Make a checklist to fulfill the task at hand and streamline your work. Keep everything detailed and focused. Less is more. The more you can remove while maintaining vital tasks, the better. It will help you stay focused on the right things to help you complete tasks. It will help you reduce errors, stay organized, and achieve goals. Allocate sections to the right personnel to boost your productivity.
## Breakdown Checklists to Multiple Sections
It's vital to break down your checklist into multiple sections. We've done this for our blog articles to keep our work organized and focused. It has different parts going into it, as we've discussed above. We do this when making the preparation, writing the article, making a thumbnail, and distributing. We do this for our company and have different checklists for different projects. It helps our team accomplish their goals and increase productivity. The checklists break down larger tasks into smaller manageable steps. The checklist we use in the devs project differs from the checklist we use for our articles in the MartinBaun.com project. 
We use our project management tool to help us manage our projects better. The Deves project has this checklist containing personal goals and specific tasks. Each person takes actionable steps to get more done.
This checklist has a list of tasks different from the MartinBaun.com project.
Each checklist focuses on the tasks that help boost our business productivity. They ensure that important goals are met. These checklists are adaptable and amenable to change if needed. We've added new items and vital steps to our checklists and removed some sections to optimize them. There's not much required to make checklists work well. You can customize the checklists and play around with them to help you fulfill your goals.
## Kill your Ego
You'll not get it right the first time. Creating checklists takes some regular revisions to get right. People will use them in the wrong way, and you'll also use them wrong wrong intermittently. Your task management will be slow and bulky. It will gradually improve. We have iterated over some of the checklists in our company. We have done this over 50 times to get our checklists well-curated. They've improved across each iteration, and this has become a game-changer in our company. We have checklists that aren't optimized. We're working to improve them. These checklists help us achieve all that needs to be done in our company.
## More about Checklists
I discovered checklists from a book I read. The Checklist Manifesto is the book that introduced me to this wonderful asset. I started applying it in my life and business. It has worked well, improving my time management skills and helping me achieve my goals. A simple online search or ChatGPT can help you find a good checklist to use as a template and improve your checklist. You can achieve your goals using this powerful tool. They are easily customizable to fit your needs. Try them today to help boost your productivity.
## The Checklist of Life
It's vital to remember the checklist of life. It has four aspects you can follow at the start of your day and the rest of your life. You do awesome stuff, eat meat, have fun, and learn. Life is a long journey with different trials and tribulations. Take time to do things you love, stay healthy, and learn as much as possible. You'll achieve things you never thought possible. Stop wasting time, plan your activities with this powerful tool, and watch your life transform.

Layout patterns play an important role in web design. It constitutes the experience a user gets when engaging with that webpage. By providing a consistent structure, it becomes intuitive and easy to navigate. The layout design also plays a role in usability. Users can easily find the necessary information with a logical and intuitive flow. It also contributes to accessibility by ensuring the webpage is accessible to all users. A thoughtfully designed website creates visual appeal, thereby increasing user engagement.
In this blog post, you will learn about the Holy Grail layout pattern, components, and structure. You will also see how it adapts to different screen sizes, scenarios for implementing the layout, and a technique for creating the Holy Grail layout.
## The Holy Grail Layout Pattern
The Holy Grail layout patterns differ from the more common layout patterns in CSS, such as single-column, two-column, and [Grid](https://www.w3schools.com/css/css_grid.asp) layouts. It uses a combination of CSS techniques such as [flexbox](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_flexible_box_layout/Basic_concepts_of_flexbox) and grid, CSS floats, or grid to create comprehensive layouts. The layout consists of a header, a footer, and three content columns of equal heights. The three content columns comprise a left sidebar, main content, and a right sidebar.
Here’s a visual representation:
*This illustration shows the structure of the Holy Grail Layout pattern on a webpage.*
## Core components of the layout
There are core components that make up the Holy Grail Layout. Examine them below.
### The header
The header is at the top of the webpage and contains features such as the company name, logo, navigation menu, search features, and slogan.
It serves as an introduction to the website and provides users with easy access to important navigation links, allowing them to quickly access information.
### The footer
The footer is the last element at the bottom of the page. It contains contact details, information regarding the company, social media links, copyright notices, and additional navigation links. The navigation link provides quick access to sections of the webpage without the need to scroll back to the top.
### Main content
As the name implies, the main content contains primary information about the company. It includes information such as the services the company renders, testimonials, product listings, and other relevant information about the company’s business.
### Sidebars
Sidebars are extra content areas located on the left and right sides of the main content. They are often used to display secondary content such as navigation menus, related links, or supplementary information.
The main content and the sidebars are positioned between the header and the footer.
## Structure of the Holy Grail Layout
There is a structure that is expected to implement the Holy Grail layout. Let's delve into the details of it.
One key aspect is that the sidebars and main content are expected to maintain equal heights regardless of the amount of content in each column. In the HTML source, the main content should also be placed first in the HTML markup before the sidebars since it contains the most important information. This way, it improves accessibility and search engine optimization ([SEO](https://developers.google.com/search/docs/fundamentals/seo-starter-guide)) by highlighting the most important information early in the document.
The layout is also expected to have fixed-width sidebars and fluid-width main content. This ensures that the main content occupies more of the viewport width, and the sidebars have a fixed width since they contain supplementary information. Another crucial element is ensuring that the footer remains at the bottom of the page, maintaining visual hierarchy and consistency throughout the website.
Overall, the layout requires minimal markup and CSS to facilitate easy maintenance and reduce page load times.
The HTML markup structure for the Holy Grail layout is as follows:
```html
<body>
<div class="container">
<header>
<!-- Holy Grail Layout -->
</header>
<div class="main-content">
</div>
<div class="left-sidebar">
<!-- Navigation menu -->
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
</div>
<div class="right-sidebar">
</div>
<footer>
<!-- Footer content -->
</footer>
</div>
</body>
```
The markup is kept simple, only containing the required elements. The main content also come before the sidebars.
<CTA_Middle_Design />
## Advantages of using the Holy Grail Layout in web design
This layout has features that distinguish it from other layouts. Consider its benefits:
* The layout organization makes it easy for users to engage on the webpage by intuitively guiding users. This results in a more engaging and satisfying experience.
* The layout brings together all elements into distinct sections, contributing to easy navigation and user interaction. It allows users to easily locate and access different parts of the webpage.
* The Holy Grail Layout considers accessibility by providing a logical and intuitive structure for the webpage. It ensures screen reader compatibility.
* The nature of the layout accounts for flexibility and responsiveness for different screen sizes and devices. Taking up all the available viewport width ensures a consistent and visually pleasing experience across devices.
* The Holy Grail layout pattern's modular and reusable nature makes the development and maintenance process easy for web developers and designers. Updates and modifications to the website can easily be made.
## Common Use Cases in Web Design
In this section, we'll go through some examples of websites that closely resemble the Holy Grail layout pattern.
One such website is LinkedIn. LinkedIn's website uses a Holy Grail layout with a LinkedIn logo header, search feature, and navigation links. The main content is divided into three columns: news feed, sponsored content, and notifications.
LinkedIn does not have a traditional footer at the bottom since the news feed is designed to be endless, and the website focuses on content.
Another website that closely resembles the Holy Grail layout is the [Bootstrap](https://getbootstrap.com/docs/4.1/getting-started/introduction/) documentation. The bootstrap documentation uses a header and multiple columns for documentation sections, code samples, and a navigation menu. The documentation also does not have a footer at the end of each webpage because it focuses on providing information about the Bootstrap framework.
Finally, CNN's website employs the Holy Grail layout to showcase news, articles, and other content. It contains a header with the CNN logo and navigation links, a footer with links to different website sections, and a main content divided into three columns of news articles, advertisements, and related content.
Depending on their specific needs, websites may employ variations different from the ideal Holy Grail layout pattern. This is possible due to the versatile approach of the Holy Grail layout to web design.
## Scenarios for implementing the Holy Grail layout pattern
There are certain scenarios where implementing the Holy Grail layout is suitable.
A common scenario is websites that contain a significant amount of content. Multiple columns and sidebars are beneficial in such cases, making it easy for users to navigate and access information. Another noteworthy use case is e-commerce platforms, as they can benefit from the structured organization of the layout. The navigation links, product listings, advertisements, and other platform sections can be allocated accordingly.
Also, websites prioritizing responsive design can leverage the Holy Grail layout to ensure an optimized user experience.
## Implementing the Holy Grail Layout
CSS Grid can be used to achieve the Holy Grail layout pattern. In this section, we'll demonstrate the styling used to achieve the layout and optimize for user experience with responsive design.
Here's the styling following the markup code above:
```css
.container {
display: grid;
grid-template-columns: 200px 1fr 200px;
column-gap: 20px;
}
header {
grid-column: span 3;
text-align: center;
border-bottom: 1px solid #ddd;
}
.left-sidebar {
padding: 30px;
border-right: 1px solid #ddd;
}
.left-sidebar li {
text-decoration: underline;
list-style: none;
}
.main-content {
padding: 30px;
}
.main-content img {
width: 100%;
height: auto;
}
.right-sidebar {
padding: 30px;
border-left: 1px solid #ddd;
}
.right-sidebar ul {
list-style: none;
}
footer {
border-top: 1px solid #ddd;
grid-column: span 3;
text-align: center;
padding: 30px;
}
```
In this snippet, the container is made into a grid container. The left and right sidebar are given a fixed width of 200px, while the main content takes up `1fr` of the remaining space. The header is made to span across three columns of the grid, thus giving it its characteristic full-width position.
The `footer` also spans across the three columns of the grid at the bottom of the page.
When the browser is resized to be smaller, the style will appear disorganized, so a responsive design will be employed to enhance the user experience.
```css
@media screen and (max-width: 1200px) {
.left-sidebar {
grid-column: span 3;
border-right: 0;
border-bottom: 1px solid #ddd;
}
.left-sidebar li {
display: inline-block;
margin-right: 10px;
}
.main-content {
grid-column: span 2;
}
}
```
When the screen width is at `1200px` or less, the `left-sidebar` spans the 3 columns making it a full-width, while the `main-content` spans two columns horizontally making it more prominent than the right sidebar.
To further make the layout responsive for smaller screens:
```css
@media screen and (max-width: 980px) {
.left-sidebar,
.main-content,
.right-sidebar {
grid-column: span 3;
}
.right-sidebar {
border-left: 0;
border-top: 1px solid #ddd;
}
}
```
When the screen width is at a maximum of `980px`, the `left-sidebar`, `main-content`, and `right-sidebar` spans all 3 columns making the style appear on one column vertically.
## Best practices for the Holy Grail layout implementation
Certain practices are recommended to ensure a seamless implementation of the Holy Grail layout.
These practices include the use of semantic HTML elements such as `<header>`, `<footer>`, `<main>`, and `<aside>`, which enhance accessibility and improve search engine optimization (SEO). In addition, the columns are expected to have equal height using CSS techniques regardless of the content length in each column. It is also important to ensure the layout is responsive by using media queries to adjust the layout based on viewport size.
Finally, you should test the layout across different browsers to ensure compatibility.
## Challenges and Considerations
While the Holy Grail layout pattern offers many benefits, there are also challenges that you should be cautious of. Consider some of the challenges that could be encountered when working with the Holy Grail layout.
* Equal Height Columns: One of the main challenges of the Holy Grail layout is achieving equal height columns. This can be a hassle, particularly when the content in each column varies in length.
* Responsive Design Complexity: Implementing responsive design in the Holy Grail layout can be a stretch, especially when ensuring that the layout remains visually appealing and functional across different screen sizes and devices.
* Cross-Browser Compatibility: Different web browsers may interpret CSS and layout rules differently, so the layout is displayed differently across browsers. Ensuring cross-browser compatibility will require more effort.
* Semantic Markup Challenges: Maintaining a clean and accessible markup while achieving the desired layout may require careful planning and organization.
## Conclusion
This article discussed the efficient and not-too-popular Holy Grail layout. We delved into its purpose, importance, and advantages. We also discussed scenarios for implementing it and implemented it using the CSS Grid technique. Finally, we reviewed the best practices and challenges of working with the Holy Grail layout.

1,867,509 | Should You Outsource OutSystems Development? Here are 6 Crucial Factors to Consider | Low-code development platforms such as OutSystems have emerged as a game-changer for organizations... | 0 | 2024-05-28T10:47:30 | https://dev.to/suarezsara/should-you-outsource-outsystems-development-here-are-6-crucial-factors-to-consider-3j0c | lowcode | Low-code development platforms such as OutSystems have emerged as a game-changer for organizations looking for rapid application delivery. Low-code platforms can slash development time by as much as 60%, owing to their visual development environment, drag-and-drop capabilities, and pre-built components and connectors.
To maximize the value of their OutSystems investments, businesses often consider outsourcing all or some of their low-code development needs. While outsourcing can help save time and money, it can also result in glitches or project failures if not managed properly.
Now the question is-how do you know when it's the right time to outsource? To help you make an informed decision, we have come up with 6 scenarios where it may be better to outsource than keep your development completely in-house:
**1. You’re Likely to Miss Development Deadlines**
One of the most common challenges for a software development company is their internal teams missing deadlines. In such cases, collaborating with skilled outsourced OutSystems experts can keep their projects on track.
When development timelines are slipping, companies often try to bridge the gap by hiring internal resources; this can be both time-consuming and cost-prohibitive. To begin with, you may have difficulty finding qualified candidates. Then the entire hiring process-from screening to onboarding-may take up to 1-3 months.
Outsourcing helps you address the challenge by providing on-demand access to a wide array of skills from diverse teams across the world. This way, you can get your product to the market quickly, and don’t need to rely solely on your in-house team with limited capabilities. Plus, you can borrow innovative ideas to iteratively improve your product.
**2. Your In-House Team Lacks the Skills Needed**
Outsourcing a portion of your OutSystems development makes perfect sense when you need a specialized skill that your in-house team lacks.
Outsourcing companies usually specialize in certain niches, so they can bring expertise that may be difficult to find locally. For instance, if your organization requires competent OutSystems developers, QA engineers, or managers to execute your project, outsourcing can help you effectively cater to your needs by providing immediate access to talented individuals. Also, you can complete projects more cost-efficiently as there is no need to seek, recruit, and onboard qualified professionals.
**3. You Want to Focus on Your Core Competencies**
Outsourcing provides you the opportunity to delegate intricate tasks to experts, allowing you to focus on what you do best-driving growth and delivering exceptional customer experiences. You can then divert internal resources and effort to activities that enhance your competitive advantage.
For instance, consider a technology company looking to build a customer support application using OutSystems. If the company has little experience in OutSystems-based development, they’d be better off outsourcing their work to a trusted service provider. By doing so, they can focus on their strengths while getting the software delivered on time and within budget.
**4. You Want to Stay Within Budget**
One of the key benefits of outsourcing OutSystems development is that it enables companies to leverage economies of scale and other cost optimization measures, so that the development cost stays within budget. Also, organizations get the opportunity to utilize emerging technologies to improve their product without requiring to invest in training or expensive hardware. They can utilize the skills of external vendors to launch cutting-edge business solutions-no need to worry about keeping pace with the changes in the underlying technology.
Outsourcing also provides access to a wide range of resources from geographies with labor costs much lower than yours. So, businesses, especially startups and smaller organizations, can access the full range of OutSystems development services without straining their IT budgets. Plus, several outsourcing companies offer flexible payment options, so you have better control over your budget.
With outsourcing, organizations can enjoy tremendous cost savings that could have been spent on hiring new workforce. They don’t need to pay for employee benefits such as health insurance, paid time off, fringe benefits, and more. As a result, they can deliver high-performing solutions that fulfill their customer needs at a fraction of what they would have spent had they developed the solution internally.
**5. You Seek Flexibility and Scalability**
Many organizations do not find it practical to [hire OutSystems developers](https://www.damcogroup.com/hire-outsystems-developers) when they need experts only for short-term projects.
For example, if you need OutSystems talent just for modernizing an existing application, hiring new people doesn’t make sense, as there may not be sufficient projects to keep them occupied. You’ll need to pay them full salaries even during times when they aren’t working on any project.
In all such scenarios, outsourcing offers the flexibility and scalability you are looking for. You can decide the size of your team and ramp it up or down quickly, depending on your business needs. This also helps you save time and resources.
**6. You Want to Mitigate Risk**
It's often said that diversifying your investment portfolio reduces your risk of financial loss. This same principle can be applied to OutSystems development outsourcing. By outsourcing, you can effectively mitigate risks while reaping significant benefits.
Rather than relying only on your in-house team, you can reduce business risk by distributing key development operations and components across multiple agencies.
But to make the most of your collaboration, it’s vital that you select your outsourcing vendor carefully, and assess their industry experience, track record, and client ratings to make an informed decision.
## Unlock the Full Potential of OutSystems with Outsourcing
Delegating your software development to trusted service providers enables your organization to stay ahead of the digital curve by providing access to top-tier talent and advanced technologies without denting your budget or taking up your valuable time. Organizations can leverage external talent to drive efficiency and cost savings while achieving unparalleled results in a timely manner. Whether you are unable to meet your deadlines, lack the necessary in-house skills, want to focus on competencies, or need a flexible development process, outsourcing can be an ideal solution to fulfill your business needs. | suarezsara |

Back in 2018, I decided to use my free time to help modernize a family member’s business. Along the way, I wanted to gain some experience and understanding of AWS.
Ultimately, I discovered that nearly all my free time was spent learning AWS cloud infrastructure concepts. I had only a small fraction of my time left to focus on building the modern, cloud-based solution that I originally had in mind. As I planned more feature requests for the app, I realized that I needed a better approach.
In early 2020, I discovered Heroku. Since I didn’t need to worry about underlying cloud configurations, I could focus my time on adding new features.
The Heroku ecosystem worked out great for my simple use case, but I began to wonder about more complex use cases. What about the scenario where a **collection of secure and private services** **needs to interact with one another** for a payment processing solution?
Would this use case force me to live in the ecosystem of one of the big three cloud service providers? I’m going to find out.
## **The Current State of Secure Microservices**
For several years, I was fortunate to work in an environment that valued the DevOps lifecycle. The DevOps team handled all-things-cloud for me, so I could focus on architecting and building microservices to meet my customers’ needs.
During that time of my life, this environment was the exception, not the norm. I just did a search for “companies lacking cloud infrastructure knowledge” in my browser, and the results yielded some pretty surprising conclusions:
* There is a serious shortage of cloud expertise.
* The lack of cloud skills is leading to significant performance impacts with cloud-native services.
* Cloud security is a challenge for 1 in 4 companies.
The top search results talked about a **lack of understanding** of the core cloud concepts and the need for **crucial training** for teams to be effective. The training most teams need usually falls by the wayside as customer demands and deliverables take higher priority.
With this current approach, most cloud implementations are forced to move at a slower pace, and they’re often exposed to unknown vulnerabilities.
The current state of securing your microservices in the cloud is not a happy one.
## **The Ideal State for Secure Microservices**
The ideal state for cloud-native solutions would adhere to a personal mission statement I established several years ago:
> **“Focus your time on delivering features/functionality that extends the value of your intellectual property. Leverage frameworks, products, and services for everything else.”**

In this context, those with a directive to drive toward cloud-native solutions should be able to move at a pace that aligns with corporate objectives. They shouldn’t be slowed by the learning curve associated with underlying cloud infrastructure.
So, what does this look like when we’re facing a cloud solution encompassing **multiple microservices**, all of which need to be **isolated from the public** and **adhere to compliance regulations** (like SOC, ISO, PCI, or HIPAA)?
## **About Private Spaces**
My 2020 Heroku experience was positive. So I wanted to see how it would work with this complex use case. That’s when I discovered [Private Spaces](https://devcenter.heroku.com/articles/private-spaces).
Private Spaces are available as a part of Heroku Enterprise. They’re dedicated environments for running microservices within an isolated network. This approach allows teams to deploy their services into a network that’s not exposed to the public internet. Under the hood, these services function exactly the same as in my basic use case. I can set them up through the Heroku CLI, and simple Git-based commands can trigger deployments.
For the regulatory [compliance](https://www.heroku.com/compliance) needs, I can lean on [Heroku Shield](https://www.heroku.com/shield) to help me comply with PCI DSS, HIPAA, ISO (27001, 27017, and 27018), and SOC (1, 2, and 3).
At a high level, Heroku lets me implement a secure cloud-native design that can be illustrated like this:
Here, we have an implementation that leverages Heroku Shield all within a Private Space. This allows a collection of microservices—utilizing several different programming languages—to interact with all the major primary and secondary card networks, all while adhering to various regulatory compliance requirements. Additionally, I get secure communications with the Salesforce platform and GitLab.
### **Heroku in Action**
Using the Heroku CLI, I can get my Private Space and Heroku Shield up and running. In Heroku, this is called a [Shield Private Space](https://devcenter.heroku.com/articles/shield-private-space). Here are some high-level examples to work through the process.
To create a new Shield Private Space, we use `spaces:create` and add the `--shield` option.
```plaintext
$ heroku spaces:create payment-network --shield --team payments-team --region oregon
Creating space payment-network in team payments-team... done
=== payment-network
Team: payments-team
Region: oregon
State: allocating
```
If the use case requires Classless Inter-Domain Routing (CIDR) ranges, I can use `--cidr` and `--data-cidr` flags.
You’ll notice that I created my Private Space in the oregon region. You can create a Private Space in one of 10 available [regions](https://devcenter.heroku.com/articles/private-spaces#regions) (in the U.S., Europe, Asia, and Australia). For a list of available regions, do the following:
```plaintext
$ heroku regions
ID Location Runtime
───────── ─────────────────────── ──────────────
eu Europe Common Runtime
us United States Common Runtime
dublin Dublin, Ireland Private Spaces
frankfurt Frankfurt, Germany Private Spaces
london London, United Kingdom Private Spaces
montreal Montreal, Canada Private Spaces
mumbai Mumbai, India Private Spaces
oregon Oregon, United States Private Spaces
singapore Singapore Private Spaces
sydney Sydney, Australia Private Spaces
tokyo Tokyo, Japan Private Spaces
virginia Virginia, United States Private Spaces
```
For each microservice that needs to run in the `payment-network` Private Space, I simply add the `--space` option when running the `apps:create` command:
```plaintext
$ heroku apps:create clearing-service --space payment-network
Creating app... done, clearing-service
```
To grant consumers access to the `payment-network` space, I can maintain the allow list of trusted IPs:
```plaintext
$ heroku trusted-ips:add 192.0.2.128/26 --space payment-network
Added 192.0.2.128/26 to trusted IP ranges on payment-network
▸ WARNING: It may take a few moments for the changes to take effect.
```
## **Conclusion**
Teams are often given a directive from above to adopt a cloud-native approach. But many teams have a serious gap in understanding when it comes to deploying secure cloud architectures. If you’re using one of the big three cloud providers, then bridging this gap will come at a price—likely missed timelines expected by the product owner.
Is there a better option for secure cloud deployment? I’m thinking Private Spaces combined with Heroku Shield represents that better option. For me personally, it also matters that Heroku is part of the solutions platform from Salesforce, which has a history of dedication to providing a cloud adoption alternative focused on the success of their customers. So I felt like this was a long-term strategy for consideration.
Have a really great day!

In 2013, React.js, the most popular JavaScript library, was developed for making distinct user interfaces. Due to its extra functionality, adaptability, and user-friendliness, developers have adopted it as a programming language. And now there's a huge demand in React Native App Development!
It will be vital for maintaining the new developments and changing trends. Furthermore, these will show the impact on how React.js development is structured going forward in the future for the projects.
This blog will provide a brief and in-depth resource for React Native application development. It will also reveal the main trends in React Native app development that are expected to appear in 2024. Also, you must hire dedicated React developers, which is necessary for your businesses to stay ahead in the competition of the digital era.
Why is React.js so popular, and what does it mean in app development?
Facebook created a JavaScript toolkit called React.js which helps the coders to design user interfaces for web and mobile applications. As it is a component-based framework, where the experts can create innovative user interfaces by interconnecting with the different components. Due to its scalability and ease of use, React has been very popular nowadays. Because of this, it has become the most convenient for many web development projects. React's virtual DOM features, component reusability, and effective data binding make it easy for developers to make dynamic and responsive user experiences with little to no expertise in programming language. The huge number of third-party libraries that are compatible with React also makes it a popular choice for certified coders who want to expand the functionality of their applications quickly.
React Trends 2024
React.js has become the most popular and most used frontend web development framework for technology upgradation. As a result, developments in React.js are always visible, by implementing new features and updates with the market dynamic. The following are some trends in React.js development to watch out for in the near and distant future:
React Native:
React.js is the base for the well-known open-source React Native mobile app development technology. It makes it possible for expertise to develop native mobile apps for both iOS and Android OS using a unified codebase. Thus, with the increasing need and requirements for mobile apps, React Native is becoming a more preferred choice among app programmers.
Static Site Generators:
Gatsby, Next.js, and Nuxt.js are popular static site generators for React.js development as they provide faster page loads, better user experience, and improved SEO. They are perfect for developing websites that need to load quickly and consistently.
Component-Based Design Systems:
As they deliver a modular and scalable method for designing and building user interfaces, component-based design systems are gaining popularity in the React.js development community. They increase consistency and save time by enabling React engineers to reuse code and design patterns across projects.
Serverless Magic:
React developers should accept the serverless design in 2024, which has recently gained popularity. Programmers may concentrate on building code instead of worrying about maintaining server infrastructure because of serverless computing.
Scalable and affordable solutions are made possible by services like AWS Lambda and Azure Functions, which allow React app developers to create apps that are not only effective but also simple to scale.
TypeScript Grows Up:
TypeScript is becoming increasingly popular, and in 2024, the React ecosystem should continue to use it. With TypeScript offering static typing, developers may improve code maintainability and identify errors early in development.
TypeScript is a statically typed combination of JavaScript that will see greater acceptance in the ecosystem as more React projects use the programming language. React and TypeScript together offer a powerful programming environment that is robust, smooth and flexible.
Integrating React with Machine Learning:
The interconnection between React.js and machine learning (ML) will be enhanced in 2024. React architects will mostly incorporate ML models into apps. Through intelligent automation, predictive analytics, and personalized content recommendations, this development aims to enhance user experiences. In addition, programmers can create dynamic, innovative, and engaging online applications by merging React.js with machine learning frameworks like scikit-learn or TensorFlow.js.
Concurrent Mode to Boost Speed:
In 2024, React Concurrent Mode will actively tackle rendering performance issues as it prepares to become a standard procedure. Also, by enabling React to manage several tasks at once, this functionality improves the overall responsiveness of applications. Therefore, programmers should expect Concurrent Mode to get enhanced, by confirming its place as an significant component of React development and opening the way for even more engaging and responsive user interfaces.
Enhanced Interoperability:
As new advancements occur annually, the direction of technology could be more precise. These days, wearable technology such as watches is becoming more popular, major tech companies strongly support Virtual Reality (VR), and the Internet of Things (IoT) is becoming more important in the app development process. The future of React Native development is excellent and secure as more consumers want apps for these new devices or gadgets. React Native app development appears to be in a perfect position to adapt to these developments and continue to play a significant role in how we craft the future things.
ESLint Plugin:
In this, your code follows best practices and is consistent; React now provides an official ESLint plugin. This plugin promotes coding techniques that improve code quality and maintainability and assists in identifying frequent errors. Hence, this is beneficial for the teams who are looking to create excellent React apps.
Suspense for Data Fetching:
React Suspense for Data Fetching changes how we handle displaying and loading states by streamlining the administration of asynchronous data fetching. This feature minimizes boilerplate code and makes sure that your apps show loading statuses appropriately by offering a consistent way to handle the asynchronous data fetching and event handling. Thus, the user experience is improved by suspense as it provides more control over UI rendering as data/ information is being fetched.
Integration of GraphQL:
In React, GraphQL is a query language for the APIs which is becoming quite popular. In 2024, React.js is being merged with GraphQL and is expected to be the most popular trend. This combination allows programmers to organize and retrieve data effectively, leading to quicker and more streamlined programs. Combining GraphQL with React.js is anticipated to increase building flexibility and streamline retrieving data for modern web apps.
Evolution of State Management:
Developing React.js has always required careful state management consideration. We should anticipate a change in state management patterns and libraries in 2024. The main goals of innovations in this field will be to streamline state management, improve its intuitiveness, and maximize efficiency. More streamlined solutions that meet the unique requirements of their apps are stored for developers.
WebAssembly and React:
WebAssembly (Wasm) enables programmers to execute code composed in C and C++ at speeds close to native web browsers. The combination of WebAssembly and React.js is anticipated to create new opportunities for speed optimization in 2024. Thanks to this combination, businesses can make more intricate and resource-intensive apps within the browser.
The architecture of Micro Frontends:
It is assumed that in 2024, the React.js ecosystem will see an improvement in the usage of micro frontends because the architectural solution will extend the microservices concept to the front end. This technique involves dividing the large monolithic frontend programs into smaller, more manageable components created separately. This method simplifies upgrades and maintenance, increases scalability, and fosters team autonomy.
**Conclusion**
React.js is still developing and will present new trends in 2024 that will influence the web and mobile app development sector. However, considering the increasing popularity of React Native and TypeScript, as well as the integration of machine learning and innovations such as Concurrent Mode, React developers are well-positioned to provide innovative and efficient solutions. However, A React app development is essential as the ecosystem adopts technologies like WebAssembly, GraphQL, and micro frontends. Suppose you want to remain ahead in this dynamic industry. In that case, you should contact an experienced Software Development Company for scalable, cutting-edge solutions in the constantly changing digital world.

Welcome back to my blog where I document the things I learned in web development. I do this because it helps retain the information and concepts as it is some sort of an active recall.
On days 24-26, I built a to-do app, a program that converts decimal numbers to binary, and a program that can filter elements, in my case, football players. Because of these projects, I was able to learn modern Javascript methods, utilize `localStorage` property, and recursion where a function calls itself.
9 things I did to practice my coding skills:
1. Building a data structure by assigning an empty object to a variable.
2. Destructuring assignment syntax to refactor code in building an app that can filter elements (football players).
3. Worked with more ternary operators, template literals, and switch case statements.
4. Finally determined that the parameter is just a placeholder for the current element being processed in the array _(lol about damn time)_.
5. Learned how `localStorage` works, a web storage feature of JavaScript that lets you persist data by storing it as a `key:value` pair. So the data can be saved in the initial session and will be there for future sessions.
6. Learned how to open and close the forms in building a to-do app using the `.toggle()` method.
7. Using the `.preventDefault()` method on an event to prevent a browser from refreshing the page after pressing the submit button
8. Utilizing the `parseInt()` function to convert a string to a number in Javascript because inputted values in HTML are returned as string.
9. Call stack is a LIFO _(last in, first out)_ data structure where top of the stack is at the end while bottom of the stack is at the beginning. Also, functions called go to the end while functions returned get removed from the end.
These projects improved my JavaScript skills and made me realize its versatility in giving functions to a website. Each one gave me practical insights and sharpened my problem-solving abilities, pushing me further into web development.

We have React, Vue, and now HTMX, but in general, frontend, despite the framework, is one thing at the core: JavaScript, HTML, and CSS.
Modern developers face a major problem when it comes to reusability. This issue is not within their current project but arises when they create another project and can't easily reuse parts of the code.
In this article, we are going to discuss the method I use to reuse my code across multiple projects with minimal bundle size and almost zero boilerplate and zero NPM installs.
## What Makes Code Reusable
First before we even start, we need to discuss what makes code reusable. The features and the specification that are necessary to make everything reusable.
**Modules**
The first thing is external modules. The fewer modules a component depends on, the more reusable it becomes. For example, in Angular or Next.js apps, we often have many npm installs, which makes reusability difficult.
**Props**
By giving a component a lot of props, we make it configurable. Dynamic properties need to exist for us to achieve our goals. Especially when it comes to text, size, or color, all of these need to be able to change through props.
**Plug n Play**
This is really important, maybe the most important of the three. Depending on SSR or other ways of rendering usually makes plug n play vanish. By using native web features like web components or by using [**JsDelivr**](https://www.jsdelivr.com/), which we will talk about later, we ensure that our components can plug n play in any project just by importing them.
## Tech Stack
Now we are going talk to about all the fun staff. The tech stack of my choice when it comes to frontend development is Web Components with Lit and Tailwind.
The whole purpose of frontend is for the rendering to be on the frontend, or it is no longer frontend it becomes backend development. I understand that SSR in a lot of cases is useful, but for most project SSR is just useless.
Let's see an example:
The first thing is to have a simple html file, no need for frameworks or libraries.
```xml
<!doctype html>
<html class="scroll-smooth" lang="en">
<head>
<meta charset="UTF-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
<title>Project</title>
</head>
<body>
<main id="outlet"></main>
<script type="module" src="/src/entry-client.js"></script>
</body>
</html>
```
Next, we need an `entry-client.js` file, which we will use for rendering our page. Also as you can see I am using vaadin router to handle multiple pages
```javascript
import {Router} from 'https://cdn.jsdelivr.net/npm/@vaadin/router@1.7.5/+esm';
import './pages/index.js'
const router = new Router(document.getElementById('outlet'));
let routes = [
{
path: '/',
component: 'home-page',
},
{
path: '/sign-up',
component: 'sign-up-page',
},
{
path: '/sign-in',
component: 'sign-in-page',
},
{
path: '(.*)',
component: 'not-found-page',
},
];
router.setRoutes(routes);
```
The components are simple Lit Web Components where we import lit from JsDelivr and our styles.
```javascript
import {css, html, LitElement, unsafeCSS} from 'https://cdn.jsdelivr.net/npm/lit@3.1.3/+esm';
import styles from '../index.css?inline'
class HomePage extends LitElement {
static styles = css`${unsafeCSS(styles)}`;
render() {
return html`
<div>Homepage</div>
`;
}
}
customElements.define('home-page', HomePage);
```
For those who will say these way of writing frontend has a lot of disadvantages you can read another article I wrote explaining why this is simply not true.
%[https://x.com/sotergreco/status/1792477974932926469]
## ESM and JsDelivr
Migrating to ESM can really benefit you because you will completely move away from npm installs. As we all know, the JavaScript ecosystem has its issues, so the less of it we use, the better.
Also, every module you might think of can be used from JsDelivr, and it will work the same.
You need to keep in mind that by using Vite when you build your application, you will have a very small bundle size. This means that the performance of your application will be excellent.
Let's take a look at an example component to understand the usage of JsDelivr and how Web Components are game changers when it comes to reusability and performance.
This is a sign-in form component I have in one of my project.
```javascript
// Importing directly from jsdelivr gives me the advantage
// when I copy and paste the component to another project
// to work just fine
import {LitElement, html, css, unsafeCSS} from 'https://cdn.jsdelivr.net/npm/lit@3.1.3/+esm'
import {Router} from "https://cdn.jsdelivr.net/npm/@vaadin/router@1.7.5/+esm";
import '../elements/x-button.js'
import '../elements/icon-button.js'
import '../elements/alert-card.js'
import styles from '../index.css?inline'
import endpoints from '../endpoints.js'
import axios from 'axios'
import {globalState} from '../global-state.js'
export class SignInForm extends LitElement {
static styles = css`${unsafeCSS(styles)}`;
// Here the properties can be used to
// overwrite default values when using the component
// like this <sign-in-form email="test@test.com"></sign-in-form>
static properties = {
email: {type: String},
password: {type: String},
isError: {type: Boolean},
errorMessage: {type: String},
isLoading: {type: Boolean},
isSuccess: {type: Boolean},
}
constructor() {
super()
this.email = null
this.password = null
this.isError = false
this.errorMessage = ''
this.isLoading = false
this.isSuccess = false
this.handleChange = this.handleChange.bind(this)
}
handleChange(value, field) {
this[field] = value
}
validateInputs() {
if (this.email == null) {
this.isError = true
this.errorMessage = 'Email is required'
return false
}
if (this.password == null) {
this.isError = true
this.errorMessage = 'Password is required'
return false
}
return true
}
async handleSubmit() {
this.isLoading = true
if (this.validateInputs()) {
try {
const response = await axios.post(endpoints.login, {
email: this.email,
password: this.password
})
const data = response.data
console.log(data)
this.isSuccess = true
this.isLoading = false
globalState.setAuth(true)
globalState.setToken(data.token)
globalState.setRefreshToken(data.refresh_token)
Router.go('/dashboard')
} catch (e) {
this.isLoading = false
this.isError = true
this.errorMessage = 'Invalid credentials'
}
} else {
this.isLoading = false
}
}
firstUpdated(_changedProperties) {
super.firstUpdated(_changedProperties);
const url = new URL(window.location.href)
const token = url.searchParams.get('token')
const refreshToken = url.searchParams.get('refreshToken')
if (token && refreshToken) {
globalState.setAuth(true)
globalState.setToken(token)
globalState.setRefreshToken(refreshToken)
Router.go('/dashboard')
}
}
render() {
return html`
<div class="w-full min-w-96 h-full p-6">
<icon-button url="/" pure="true" text="Go Back" icon="arrow-back-outline"></icon-button>
<h1 class="text-3xl text-black font-bold mt-4">Sign in</h1>
<a class="mt-3 block text-xs hover:underline" href="/sign-up">
Don't you have an account? <strong>Sign-up</strong>
</a>
<div class="mt-8">
<x-button></x-button>
</div>
${this.errorMessage ? html`
<alert-card title="${this.errorMessage}" type="error" class="mt-4"></alert-card>
` : null}
<div class="mt-8">
<input-element
.handleChange="${this.handleChange}"
class="mb-4"
icon="mail-outline"
name="email"
type="email"
label="E-mail"
placeholder="Enter your e-mail"
required
>
</input-element>
<input-element
.handleChange="${this.handleChange}"
class="mb-4"
label="Password"
icon="eye-outline"
name="password"
type="password"
placeholder="Enter your password"
required
>
</input-element>
<div class="w-full flex justify-end mt-8">
<icon-button .loading="${this.isLoading}" @click="${this.handleSubmit}" type="button"
text="Sign In"
icon="arrow-forward-outline"></icon-button>
</div>
</div>
</div>
`
}
}
customElements.define('sign-in-form', SignInForm)
```
Don't be afraid of classes. The code is pretty clean and reusable. We have build in validation, tailwindcss and with a simple import everything works.
We have some moving parts, like the CSS but overall we reduce the boilerplate by 90%. This component can work on any project with minimal changes.
## Overall Simplicity
That way, by writing your frontend like this, you not only reduce boilerplate, but deployment also becomes easy, and there is zero learning curve. You can give this to any developer, and they can understand how it works.
Compare this to using Next.js, Gatsby, or even Angular. I think the future of frontend development is heading in this direction because frontend frameworks have become too cluttered and have big learning curves.
Yet, by using literally zero packages, you can create full frontend applications and websites without needing to install anything, and they are also reusable.
## Conclusion
In conclusion, writing frontend components with reusability in mind can greatly enhance your development process.
By minimizing dependencies, utilizing props for dynamic configurations, and ensuring components are plug-and-play, you can create flexible and efficient code.
Adopting technologies like Web Components with Lit and leveraging the power of JsDelivr for module management can streamline your workflow and improve performance.
This approach reduces boilerplate, simplifies deployment, and makes your components easily understandable for any developer, paving the way for a more efficient and scalable frontend development experience.

**Energy Storage Solutions:** Improved energy storage systems, such as batteries and pumped hydro storage, are essential for integrating renewable energy into the grid and ensuring a reliable energy supply.
Smart Agriculture: Precision agriculture technologies, including drones, sensors, and data analytics, enable farmers to optimize resource use, reduce waste, and increase crop yields.
**Circular Economy:** Innovations in recycling and waste management are critical for developing a circular economy, where materials are reused and recycled, minimizing waste and reducing the need for raw materials.
## The Role of Individuals in Sustainability
While policy and technological advancements are crucial, individual actions also play a significant role in promoting sustainability. Individuals can contribute by:
**Adopting Sustainable Lifestyles:** Simple changes in daily habits, such as reducing energy consumption, minimizing waste, and choosing sustainable products, can collectively have a significant impact.
**Supporting Sustainable Businesses:** By choosing to support businesses that prioritize sustainability, individuals can drive demand for environmentally responsible products and services.
**Advocacy and Participation:** Getting involved in environmental advocacy and participating in community sustainability initiatives can amplify the impact of individual efforts and drive broader change.
## Conclusion
Embracing sustainability is not merely an option; it is a necessity for the survival and well-being of future generations. By addressing the interconnected dimensions of environmental protection, economic viability, and social equity, we can build a more resilient and sustainable future. Governments, businesses, and individuals all have a role to play in this collective effort. Through policy innovation, technological advancements, and individual actions, we can turn the tide on environmental degradation and create a world where both people and the planet thrive.

1,867,191 | PHP: Laravel, Ruby: Rails, JavaScript:? | Recently, there has been a heated discussion on Twitter between JS developers and Laravel and Rails... | 0 | 2024-05-28T10:23:41 | https://zenstack.dev/blog/js-fullstack | javascript, webdev, programming, learning | Recently, there has been a heated discussion on Twitter between JS developers and Laravel and Rails developers. It started with a lengthy tweet from Taylor Otwell, author of Laravel:
{% embed https://twitter.com/taylorotwell/status/1791468060903096422 %}
In short, he suggested that the whole JavaScript ecosystem lacks a real "full stack" framework like Laravel or Rails, which could allow a single developer to build the next GitHub, AirBnb, or Shopify.
I deeply empathize with this, as I share the same goal when building [ZenStack](https://zenstack.dev/), the typescript toolkit on top of Prisma ORM. In fact, I have often heard that kind of word from our community:
No one can deny the popularity and fast-paced growth of the JS ecosystem, even among non-members. So why is it?
## The Historical Reason
> Men make their own history, but they do not make it as they please; they do not make it under self-selected circumstances, but under circumstances existing already, given and transmitted from the past -- Karl Marx
Both PHP and Ruby were designed as server-side languages from the start. PHP was created in 1994 to build dynamic web pages, while Ruby, which appeared in the mid-1990s, was designed for general-purpose programming.
Given their server-side origins, PHP and Ruby were naturally suited for comprehensive frameworks that could handle all aspects of web development, from routing and controllers to database interactions and templating engines. This led to the creation of frameworks like Laravel and Rails to offer a complete, opinionated way to build web apps.
Contrastingly, JavaScript was born as a client-side scripting language for web browsers. It had nothing to do with the backend until 2009, when Node.js was introduced. If you've heard of the "Browser Wars" between Netscape Navigator and Internet Explorer, you're likely aware of the ongoing chaos in the frontend, which continues to drive front-end developers crazy today in the name of browser compatibility. As a result, the early web was about piecing together disparate technologies. Therefore, JavaScript developers became accustomed to modularity, allowing flexibility to mix and match libraries and tools for survival. That's why NPM, which emerged alongside Node.js, has grown at an astonishing rate, quickly becoming the largest software registry in the world.
This different circumstances led to the different developer cultures:
- **PHP/Ruby devs:** "Give me a framework that just works. I want conventions, stability, and a clear path to shipping."
- **JS devs:** "Don't box me in! I want flexibility, the latest tools, and the freedom to build my way, even if it means more work upfront."
As a result, even after expanding to the backend world, a monolithic, "one-size-fits-all" approach could hardly fly in the Javascript ecosystem.
## Contemporary Endeavor
On one hand, this culture leads to constant evolution, keeping the entire ecosystem exciting and innovative. However, it also results in more decision fatigue and a steeper learning curve for newcomers.
"Where there's muck, there's brass." Some individuals embarked on an adventurous journey to build a Rails-like, battery-included framework to challenge the status quo. Here are some popular examples:
- [RedwoodJS](https://redwoodjs.com/)
Full-stack JavaScript framework that integrates React, GraphQL, and Prisma. It simplifies development with a unified setup and automatic code generation, perfect for scalable applications.
- [Biltz.js](https://blitzjs.com/)
Blitz.js extends Next.js into a full-stack framework featuring a zero-API data layer and Prisma for database access. It aims to simplify development by allowing direct server-side code calls from the frontend.
- [AdonisJS](https://adonisjs.com/)
AdonisJS is a TypeScript-first web framework for building web apps and API servers. It offers a rich set of features out-of-the-box, including an ORM, authentication, and a powerful CLI, making it ideal for developers seeking a comprehensive and structured development environment.
Will they become the Laravel or Rails of the JS world? It's probably too early to say, but at least RedwoodJS shows great momentum:
Another bunch of guys are trying to solve this problem by providing “start kits” with **opinionated** battery-included toolkits. Among these, the most popular one is [Create-T3-App](https://create.t3.gg/), which combines Next.js, tRPC, Tailwind CSS, and other powerful tools to give you a solid foundation for building typesafe web applications.
Interestingly, Theo, the creator of T3, seems to be pessimistic about this whole endeavor of JavaScript world:
{% embed https://twitter.com/t3dotgg/status/1792136001345003748 %}
## Optimistic Future
> Any application that can be written in JavaScript, will eventually be written in JavaScript. — Jeff Atwood
While I'm not entirely convinced by Atwood's law, I do envision a promising future for JavaScript in the field of web development. The reason is simple:
**It’s the first time in history that the whole web app could be developed with one programming language.**
This is a significant benefit, particularly for novice developers. Thanks to TypeScript's excellent type inference system, we are not only capable of doing it but also willing to do so.
A common critique from Laravel or Rails users is that these frameworks lack a conventional method for modeling the relationship between different entities in your system like the below:

While it may not have reached the level of Laravel or Rails, the current efforts in the JS world have recognized this issue. If you look at the toolkit of the solution mentioned above, you'll find a common name: [Prisma](https://www.prisma.io/)
If you haven’t heard about Prisma, it is a modern TypeScript-first ORM that allows you to manage database schemas easily, make queries and mutations with great flexibility, and ensure excellent type safety. This empowers JavaScript developers with a level of data handling sophistication and ease of relationship modeling traditionally found in Laravel and Rails, much like Laravel’s Eloquent ORM.
The [ZenStack](https://zenstack.dev/) toolkit I’m building on top of Prisma aims to narrow down the gap further. It adds an Authorization layer on top of the schema and then automatically generates both APIs and frontend hooks for you. So, put simply, once you're done with your schema, you're almost done with your backend. You can then choose whatever frontend framework, like React, Vue, or Svelte, to get your UI done.

## Begin With the End in Mind
Will JavaScript ever have its Laravel/Rails moment? Personally, I believe, or at least hope, that having standardized conventions leads to global optimization for the entire ecosystem. However, given the history and culture of JavaScript, achieving this may take a significant amount of time. It's unclear whether AI will accelerate this process or completely overturn it.
So, it seems we just have to wait and see. However, let's not get lost in this debate and forget our original intention, as Lee Robinson says:
{% embed https://twitter.com/leeerob/status/1792215708715122752 %}
So, I will quote a statement from the [W3C Web Platform Design Principles](https://www.w3.org/TR/design-principles/#priority-of-constituencies) at the end:
> User needs come before the needs of web page authors, which come before the needs of user agent implementors, which come before the needs of specification writers, which come before theoretical purity.

1,867,494 | Why Google Analytics is problematic, and you should move away from it | The Pro Apps team from XWiki brings a major release in terms of Pro applications — Matomo web... | 0 | 2024-05-28T10:19:25 | https://dev.to/lorina_b/why-google-analytics-is-problematic-and-you-should-move-away-from-it-4kde | The Pro Apps team from XWiki brings a major release in terms of Pro applications — Matomo web analytics integrated in your XWiki instance. 🎉 This has been a very requested application that we've worked on for the past year, and we're happy to present it to you today. So let's take a look at why you should opt for an open-source Google Analytics alternative and explore all the functionalities the [Analytics Application (Pro) brings.](https://store.xwiki.com/xwiki/bin/view/Extension/AnalyticsApplicationPro)
## Why Google Analytics is problematic, and you should move away from it
- **It's owned by one of the biggest tech giants in the world**: Google Analytics is a product of Google, one of the largest tech giants globally. Entrusting your data to an external entity raises concerns about data ownership, privacy, and potential exploitation for commercial purposes. At XWiki SAS, we emphasize the importance of maintaining control over your data rather than giving it to corporate entities that have been in public debate over the ethicality of their product.
- **It's a proprietary software**: Google Analytics is proprietary software, meaning its source code is closed and inaccessible to users. This lack of transparency hampers customization, limits innovation, and fosters dependency on a single provider. Furthermore, you are locked in with the vendor, meaning that you must accept any changes if you want to continue using the product. As you might already know, because we never lose the chance to speak about this, XWiki SAS advocates for open-source solutions that promote collaboration, transparency, and community-driven development. What's more, we believe in always having the freedom to choose where your data is stored and how it's handled.
- **It's non-GDPR compliant** (along with other regulations): Google Analytics collects a significant amount of user data. This has raised concerns about compliance with privacy regulations such as the General Data Protection Regulation (GDPR) in the EU and the California Consumer Privacy Act (CCPA) in the U.S.. Organizations using Google Analytics must ensure they comply with these regulations, which can be complex and adds additional workload to potentially multiple teams.
- **It's too complex for some use cases**: Apart from the learning curve with the new GA4 which makes adoption painful, sometimes companies need basic data easy to find and read, without building extensive reports. Here is where our new Analytics Application (Pro) stands out — you have a default dashboard with main KPIs that you can check. If the need arises, you can customize your dashboard with the desired macros or integrate a specific macro into a wiki page to have easy access only to the essential metrics.
## Why Analytics Application (Pro) is such a game changer
People have been looking for [Google Analytics alternatives](https://store.xwiki.com/xwiki/bin/view/Extension/AnalyticsApplicationPro) in order to avoid all the regulatory issues and the difficult transition to GA4. We think the new integration answers a good part of an organization's needs:
1. **Easy to find and understand your data:** One of the downsides of the new GA4 is that data retrieval is simply put painful. The significant change of the interface and reporting means that you need to learn a new tool and erase everything you used to know how to do — because now it's just different. Even for someone seasoned, it's overwhelming. In the Matomo extension from XWiki you can see at a glance how your intranet or public website is performing while also focusing on doing the things that really matter in your organization.
2. **Open source & compliant with privacy regulations:** Both products are open source and privacy-friendly. If you need only the essential information about what pages are the most visited, keywords searches, returned visitors, countries etc., you can configure Matomo in order to avoid collecting any personal data.
3. **Own & control your data: **You can maintain full control of your data, through a self-hosted Matomo server. This way, you protect your users' privacy while deciding how the data is used, without any third-parties involved.
4. **Default or customized dashboards:** The application comes with a default main dashboard that you can customize to your needs, by adding macros. Each macro comes with its own set of relevant metrics. Additionally, you can create multiple analytics dashboards for each section of your wiki to see easily the most important KPIs related to that section. Last but not least, you can insert specific macros in wiki pages for tracking or reporting. Right now, at the launch, the application offers 15 different macros (in other words, metrics) such as:
- Time range
- Visits overview
- Returning visits over time
- Site search keywords
- Most viewed pages after a keyword search*
- Entry pages
- Exit pages
- Countries
- Browsers
- and a few others.
* If some entries do not have a link to a page and have "Others" in the title, you can modify the Matomo configuration according to this page.
**"Does this app fit my organization?"** Check for the answer below.
This is a question that only you and your team can answer. What we'll do instead is provide a series of use cases that we thought of when working on the [Analytics Application (Pro)](store.xwiki.com/xwiki/bin/view/Extension/AnalyticsApplicationPro).
💼 Administrators or marketing specialists of public websites that require insights into customer behavior and content effectiveness.
🌐 Administrators of companies intranet networks that look to enhance decision-making processes, improve the level of adoption of new tools or procedures, and know what pages have the most and least traction in their organization.
🎯 Administrators of support documentation that want to identify popular pages or topics, improve content discovery, and track the success of their self-help customer centers.
🫶 NGO public website or internal wiki to understand user behavior, measure the success of their campaigns, and use the data to improve the UX.
Besides all the use cases, we think that industries that require self-hosted solutions, total ownership and control of their data can take into consideration this app.
## How to test our Analytics Application (Pro)
**For an XWiki Cloud demo**
For XWiki Cloud demos, we have created a dedicated Matomo server for testing purposes. This being said, when you create a [demo](https://try.xwiki.com), you will find in the left corner of your instance the Analytics application installed and ready to take for a spin. Start exploring your instance, create pages, and use the search bar in order to start seeing data in the Analytics Application (Pro) default dashboard.
If you enjoy the app and want to use it as web analytics for your website or for your company wiki, we recommend you configure a self-hosted Matomo instance or use Matomo Cloud. Afterward, you will need to purchase the application as listed below, and then link the Matomo server to the Analytics Application in your instance to start displaying data in your XWiki instance.
**For XWiki on-premises**
In order to test this application on your premises, you will need to configure a Matomo instance.
Next, install the extension follow these steps inside your XWiki instance:
- Go to the Extension Manager of your XWiki instance, in the Extensions subsection
- Search for the Analytics Application (Pro)
- Click on the "Install" button
- Go to Extensions Manager, Licenses subsection, and get a trial license (or an extension of the trial up to 30 days)
- Last step is to link your XWiki instance with the Matomo instance according to this documentation.
**For clients
**
If you already have XWiki Pro on-premises or on the cloud, go to the Administration section in your XWiki instance (Extensions), install it, and test it out.
## How to purchase the app
You can purchase the [Pro App](store.xwiki.com/xwiki/bin/view/Extension/AnalyticsApplicationPro) individually or as part of the XWiki Pro package.
- Go to the Administration section of your XWiki instance in Extensions -> Licenses
- Find the Analytics Application (Pro)
- Click on "Buy" next to the application
- You will be redirected to the XWiki Store, where you have to select the user tier
- Click on "Create Purchase Order"
- You will be redirected to the XWiki Network, where you will be able to complete your online purchase

Internet Protocol Television (IPTV) verandert de manier waarop we televisiecontent consumeren. In tegenstelling tot traditionele uitzendmethoden levert [iptv belgië](https://channeliptv4k.com/) televisiecontent via het internet. Deze methode biedt tal van voordelen, waaronder hogere interactiviteit, een breed scala aan kanalen en on-demand diensten. In België heeft IPTV aanzienlijke tractie gekregen en is er groeiende interesse in het gebruik en de regulering ervan, vooral in relatie tot Nederland.
Geschiedenis en Evolutie van [IPTV België](https://channeliptv4k.com/)
De adoptie van [IPTV België](IPTV België met Focus op Nederland) begon in het begin van de jaren 2000, samenvallend met de vooruitgang in internetinfrastructuur en verhoogde breedbandpenetratie. Aanvankelijk werden IPTV-diensten aangeboden door telecomreuzen zoals Proximus en Telenet. Deze diensten boden een alternatief voor kabel- en satelliettelevisie, met concurrerende prijzen en extra functies zoals catch-up tv en video-on-demand.
IPTV-diensten Beschikbaar in België
In België zijn er verschillende IPTV-aanbieders die aan verschillende klantbehoeften voldoen. Belangrijke aanbieders zijn:
Proximus TV: Biedt een breed scala aan kanalen, on-demand content en interactieve functies.
Telenet TV: Bekend om zijn robuuste service, uitgebreide kanalenlijst en gebruiksvriendelijke interface.
Orange TV: Biedt IPTV-diensten met flexibele pakketten en concurrerende prijzen.
Elke aanbieder biedt unieke functies en pakketten, waardoor het voor consumenten essentieel is om hun opties te vergelijken op basis van hun voorkeuren en eisen.
Regulering en Juridische Aspecten van [IPTV België](https://channeliptv4k.com/)
IPTV-diensten in België zijn onderworpen aan strikte regelgeving om eerlijke concurrentie te waarborgen en consumentenbelangen te beschermen. Het Belgisch Instituut voor Postdiensten en Telecommunicatie (BIPT) houdt toezicht op de regulering van deze diensten. Belangrijke regelgevende aspecten zijn licentieverlening, contentregulering en maatregelen ter voorkoming van piraterij.
Vergelijking met IPTV-diensten in Nederland
Bij het vergelijken van [IPTV België](https://channeliptv4k.com/) en Nederland komen verschillende overeenkomsten en verschillen naar voren. Beide landen hebben geavanceerde telecominfrastructuren en concurrerende markten. De regelgevende omgeving en consumentenvoorkeuren kunnen echter verschillen. In Nederland domineren aanbieders zoals KPN en Ziggo de markt, met vergelijkbare functies maar soms met verschillende contentaanbiedingen vanwege regionale licentieovereenkomsten.
Consumentenvoorkeuren en Trends
Belgische consumenten hebben een sterke voorkeur getoond voor IPTV vanwege de flexibiliteit en de mogelijkheid om kijkervaringen aan te passen. Trends wijzen op een groeiende vraag naar hoogwaardige content, multi-screen kijkopties en geïntegreerde diensten die tv combineren met internet en telefonie. Vergelijkbare trends worden waargenomen in Nederland, wat de grensoverschrijdende aantrekkingskracht van geavanceerde IPTV-diensten benadrukt.
Technologische Vooruitgang in IPTV
Technologische vooruitgang heeft IPTV-diensten aanzienlijk verbeterd. Innovaties zoals 4K-streaming, cloud DVR en geavanceerde aanbevelingsalgoritmen hebben de gebruikerservaring verbeterd. Zowel België als Nederland lopen voorop bij het adopteren van deze technologieën, gedreven door de vraag van consumenten naar hoogwaardige en gepersonaliseerde kijkervaringen.
Uitdagingen en Kansen
Ondanks de voordelen, staat IPTV voor uitdagingen zoals netwerkcongestie, contentpiraterij en concurrentie van over-the-top (OTT) diensten zoals Netflix en Amazon Prime. Deze uitdagingen bieden echter ook kansen voor innovatie en differentiatie. Aanbieders in België en Nederland zijn continu op zoek naar nieuwe manieren om de dienstverlening en contentaanbiedingen te verbeteren.
Toekomst van [IPTV België](https://channeliptv4k.com/) en Nederland
De toekomst van [IPTV België](https://channeliptv4k.com/) en Nederland ziet er veelbelovend uit, met een voortdurende groei in beide markten. Factoren die bijdragen aan deze groei zijn onder andere vooruitgang in 5G-technologie, toenemende vraag van consumenten naar flexibele kijkopties en de voortdurende evolutie van contentleveringsplatforms.

1,867,491 | Flakiness isn't from your test framework | The other week I saw Filip Hric share a post from Gleb Bahmutov, ex-principal engineer for Cypress,... | 0 | 2024-05-28T10:18:20 | https://dev.to/automatedtester/flakiness-isnt-from-your-test-framework-17pn | webdev, javascript, testing |
The other week I saw Filip Hric share [a post](https://www.linkedin.com/feed/update/urn:li:activity:7193270830271762432/) from Gleb Bahmutov, ex-principal engineer for Cypress, explaining that the way cypress works and not using transport layers like playwright or WebDriver based frameworks makes its tests less flaky.
That’s 100% not the reason your tests are flaky. I’m not going to lie, this shocked me that Gleb would say this as I’ve always thought of him as a good engineer after seeing his work on Cypress. The reason your tests are flaky is more down to how you interpret the UI and how the browser runs the code, or to put in a different way, you’re thinking about your synchronous steps of a test while they’re running in an asynchronous way. **This mismatch leads to flakiness**.
Now add in different browsers interpreting the code in different ways leads to more flakiness. This is why some frameworks don’t want to or can’t support different browsers.
## Single threadedness of JavaScript
Cypress runs in the page that’s being tested. That means Cypress is hemmed in by the [same-origin policy](https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy). It injects what it needs to the page. The problem is this means CPU has to swap in commands from different tasks. This *could* lead to less flakiness but it’s because it’s running much slower. Since there is no guarantee of ordering of commands between tests and the front end, the reduced flakiness is pure chance.
Selenium, when [Jason Huggins](https://twitter.com/hugs) created it, used this technique for automating the browser and Selenium moved away from it when we merged with WebDriver. Hugs have been calling this out for ever. It’s also the reason why you can’t do basic things like trusted events, iframes, or navigating between different [origins](https://developer.mozilla.org/en-US/docs/Glossary/Origin).
{% embed https://twitter.com/hugs/status/1177619507927490560 %}
Driving the browser from inside to outside, where outside is your webpage, is always going to give you a more realistic testing experience.
## Transport layers
The transport layer for speaking to the browser doesn’t affect the flakiness. Its main benefit is scalability. If you need your tests to run in the same browser as the runner then you struggle to scale. Since Selenium’s main transport system is based off HTTP we know it’s highly scalable. Cypress tests are less scalable because it wanted to do everything on the browser.
### but what about CDP?
What about it? It’s a chromium based protocol. Playwright uses it, Puppeteer uses it, and this might shock you, Selenium uses it. This is firstly how Edgedriver and chromedriver speak to the browser. So if you’ve used chromedriver at any point in the last 8+ years you’ve used CDP. Selenium can also speaks directly to the browser using CDP for some commands. We see this with their network intercept API and logging APIs are examples. Now, webdriverio also supports WebDriver and puppeteer through these APIs. So if we follow [Gleb’s post](https://glebbahmutov.com/blog/cypress-vs-other-test-runners/), we need to move *everything* down to playwright/puppeteer part of his diagram.
The one downside to having to rely on CDP is you limited to chromium specific APIs. These are not stable by design which the Chromium team will tell you. It’s the reason why chromedriver/edgedriver needs to be updated with each browser release. Fortunately, [Selenium Manager can auto update](https://www.theautomatedtester.co.uk/blog/2023/selenium-mananger/) your drivers for you without you needing to worry. If you're not using Selenium Manager you will have to update all your dependencies which you would have to do with Playwright or puppeteer. If you’re using the Selenium event driven APIs then you will have to update your selenium dependency.
As mentioned, it does limit us to chromium specific APIs which is why Selenium is working with Google, Apple, Mozilla, and a few other little companies to bring about the new Webdriver-bidi spec. When WebDriver-BiDi is out to all browsers then the requirements for updating with the browser will drop like they did with Firefox and geckodriver.
The [puppeteer team is supporting WebDriver-BiDi](https://developer.chrome.com/blog/webdriver-bidi/). A debug protocol is not the best for automation as it relies heavily on browser state. It’s great for debugging but not automation. Since this work is happening in the open, we are happy for the playwright and cypress team to come collaborate with us.
## How do we solve flakiness then?
Auto-waiting, minimizing what your tests are doing, and root cause analysis of failures. Webdriver.io, Nightwatch, playwright, puppeteer, and cypress have the auto waiting. All at different levels. There is some opinions that differ on what should be waited for but they are aiming for the same end result.
Selenium has had auto waiting in a minimal wait with the explicit and implicit waits. People can struggle with them. These waits are opinionated like the above. So... we're down to which opinions we like. So... if you're learning a tool for a CV... well it's just an opinion that's different. How to do web testing, and understanding it, that is the super power you need.
*As an aside, when I was at Mozilla, automattic came to us saying they wanted puppeteer support as they were dropping selenium because of flakiness... and then then the flakiness was still happening with puppeteer*
Flakiness has been around for a long time. [Simon Stewart](https://twitter.com/shs96c) wrote a [good blog post about this problem 15 years ago](https://testing.googleblog.com/2009/06/my-selenium-tests-arent-stable.html) and how to solve some of them. This is not a new problem and someone telling you their framework will solve it is lying.
Unfortunately, there will still be some flakiness… and it’s not your fault.
## Front end frameworks hate testers
These frameworks make flakiness equal when it comes to testing.
Browsers have had to put a lot of effort to improving the speed of rendering and painting to handle these because of the constant moving in and out of the DOM. These asynchronous changes to the DOM the way your tests run. In selenium you’ll hit a `StaleElementReference`. These are painful but auto waiting can solve it for you easily. Batteries included systems, like NightwatchJS, webdriverio, playwright, and cypress try make how this works opaque to the end user.
### Asynchronocity is hard
As I alluded to above, we don’t think of tests in the same way we think of rendering front end tests. When we’re wanting to take data off a server and render it, it’s all happening asynchronously due to how JavaScript and fetch APIs work. The move to server side rendering again is not going to solve this either… it’s just moving the heavy lifting around. Yes with promises we can write code that looks synchronous but that’s just for where that bit of code is. A slow response from a server can impact our tests. Having your tests and front end competing in the same thread won’t make your tests less flaky other than by sheer luck.
## Finally… work in the same world as your users
So is there any benefit to running your tests in Electron? Well… how many of your users use your site with electron? Probably the same amount as would use playwright-Firefox or playwright-WebKit. It’s a number that is very close to 0.
I’ve talked about this many times about having your tests work. It’s important to have a number of tests running in the environments where our users are. I’ve got examples in my talk from last year. Different environments, like mobile versus desktop, can also lead to different reasons for flakiness.
{% embed https://www.youtube.com/watch?v=Mo6LmFGrtxY&list %}
So… when picking a framework, pick one that works well for you. It should be able to do a [Login Test](https://www.theautomatedtester.co.uk/blog/2023/the-login-test/) easily. If it can’t then it shouldn’t be used.

1,867,490 | How I Started My Coding Journey 🚗 | Just 6 months ago, I didn't really know how to code, and coding was just this thing that only really... | 0 | 2024-05-28T10:18:16 | https://dev.to/nmiller15/how-i-started-my-coding-journey-1749 | coding, learning, beginners, story | Just 6 months ago, I didn't really know how to code, and coding was just this thing that only really smart people did. I wasn't even pursuing it. I thought it was cool, but not cool enough to learn it. I knew some basics of HTML and CSS… enough to break a Squarespace site that is. But, nothing that would make me *actually* dangerous. The word "JavaScript" sent me cowering.
In December of 2024, my life was turned on its head. In the course of one weekend, I lost a job that I loved with people that I cared about in one of the most painful and difficult experiences of my life AND I got engaged to my now fiancé AND I began the search for a new career. That weekend, and the following months were the highest of highs and the lowest of lows.
While avoiding the lows at a Browns game with my brother. (*woof* *woof*). He said to me, "you should just do one of those coding boot camps." It was an offhand comment, but coming from him, a software developer for a Fortune 500 company, it meant a lot. The more I thought about it, the more I realized that it was something that I had wanted to learn for a long time, and this was my chance.
After realizing that many coding boot camps are prohibitively expensive and that the resources available online for free didn't offer any way to show my skills to potential employers, I was a little disheartened. I eventually found Codecademy's Full-Stack Developer Professional Certification course. And full transparency, I am at 50% completion of their robust and comprehensive course. (51% at the time of posting)
Paying around $250 for Codecademy (thanks, Mom), put enough skin in the game for me to motivate me to make progress through the course. I breezed through HTML and CSS and started finally pounding my head against the wall with JavaScript. I ate up the content and project for 3+ hours every day, the rest of my time dedicated to filling out job applications and checking my email for even one response. The lessons were informative and the projects inspired new ideas of things that I could now build on my own!
Now, the website you're reading this on … if you are on [stackfacts.dev](stackfacts.dev) that is … was custom coded using React, Redux, Node, Express and like 5 or 6 other technologies that I didn't even know existed 6 months ago.
Am I an expert? Absolutely. Not.
Do I know what I'm doing? Eh. I'm figuring it out.
But, if you've ever thought, "Man, I wish I knew how to code." Or you've been putting off your first course, let me give you this. Here is your permission–no–your encouragement to just pick it up and do it. You don't have to be super smart, you don't have to be technically gifted, you don't have to be a math whiz, and you don't have to spend a ton of money and a ton of time to start seeing the joy, inspiration, confusion, frustration, and wonder that comes with learning how so much of our world works.
Let me take a break to tell you a very short story. I am a trombone player. I play in a couple local groups, mostly on a volunteer basis. But, there was a time that I seriously studied this. I have a Master's in trombone performance… (really helping me out now). Until recently, I maintained a small studio of high school trombone students that I taught weekly. I tried to pour out what I had learned on my journey and help them to become spectacular students. I did see a lot of improvement in their playing, but I consistently found my teaching come up short. So often, I overlooked small details or aspects of music or trombone-playing that came so naturally to me after 15 years of practice and study, I didn't think to teach it. A lot of it, I had forgotten how to even articulate!
Why am I telling you this? Because, if you're just starting to code, you're looking at a lot of resources that are incredibly intimidating and some that assume that you have lots of background knowledge. My goal with this blog is to create a resource that documents my journey as I learn to code and build projects.
You'd be surprised at the things you can learn or change in 6 months. So start today, and learn as you code!

```java
public class Main {
public static void main(String[] args) {
String[] array = {"A", "B"}; // 配列 array を定義し、要素として "A" と "B" を持つ
int i = 0; // インデックス i を初期化
while ( i < array.length ) { // i が array の長さより小さい間ループでAとBの要素だから2。i < 2
int j = 0; // インデックス j を初期化
do {
++j; // j をインクリメント（1 増やす）
} while ( j < array[i].length() ); // j が array[i] の長さより小さい間ループ（A の長さは 1、B の長さは 1）
System.out.println(array[i] + ":" + j); // array[i] と j の値を出力
i++; // i をインクリメント（1 増やす）
}
}
}
```
次に、実際にコードがどのように実行されるかを見てみましょう。
1. 最初に `array = {"A", "B"}` という配列が定義され、インデックス `i` が 0 に初期化されます。
2. `while` ループが開始され、`i < array.length` の条件をチェックします。この場合、`array.length` は 2 なので、`i` が 2 より小さい限りループが続きます。
3. `i = 0` のとき:
- `int j = 0;` で `j` が初期化されます。
- `do` ループが開始され、`++j` によって `j` が 1 になります。
- `j < array[i].length()` の条件がチェックされます。`array[i]` は "A" なので、`array[i].length()` は 1 です。`j` が 1 なので条件は満たされません。
- したがって、`System.out.println(array[i] + ":" + j);` が実行され、"A:1" が出力されます。
- `i` が 1 にインクリメントされます。
4. `i = 1` のとき:
- `int j = 0;` で `j` が初期化されます。
- `do` ループが開始され、`++j` によって `j` が 1 になります。
- `j < array[i].length()` の条件がチェックされます。`array[i]` は "B" なので、`array[i].length()` は 1 です。`j` が 1 なので条件は満たされません。
- したがって、`System.out.println(array[i] + ":" + j);` が実行され、"B:1" が出力されます。
- `i` が 2 にインクリメントされます。
以上のプロセスにより、出力は "A:1" と "B:1" になります。これが選択肢 C に該当するため、答えは C です。
## 追記
`array[i].length()`の仕組みについて詳しく説明します。
### 配列の仕組み
Javaでは、配列は同じデータ型の要素を格納するためのオブジェクトです。各要素にはインデックスを使ってアクセスできます。例えば、以下のように文字列の配列を定義します：
```java
String[] array = {"A", "B"};
```
ここでは、`array`という名前の文字列の配列を定義し、`"A"`と`"B"`という2つの要素を持っています。この配列の長さ（要素の数）は2です。インデックスは0から始まります。
### 配列の要素へのアクセス
配列の要素にアクセスするには、インデックスを使用します。
- `array[0]` は `"A"`
- `array[1]` は `"B"`
### `array[i].length()`の仕組み
`array[i]`は配列の`i`番目の要素を表します。`array[i]`は文字列型の要素です。そのため、`array[i]`に対して文字列操作を行うことができます。
Javaの文字列（`String`）には、文字列の長さ（文字数）を返す`length()`メソッドがあります。例えば：
```java
String s = "Hello";
int len = s.length(); // len は 5 になります
```
ここで、`s.length()`は文字列`s`の長さを返します。この場合、`"Hello"`の長さは5です。
同様に、`array[i]`も文字列ですので、その長さを取得するために`length()`メソッドを使用できます。
### プログラムでの具体例
あなたのプログラムでは、以下の部分が関連しています：
```java
int j = 0;
do {
++j;
} while (j < array[i].length());
```
- `array[i]`は、配列の`i`番目の要素、つまり文字列です。
- `array[i].length()`は、その文字列の長さを返します。
例えば、`i = 0`のとき：
- `array[0]`は`"A"`です。
- `"A".length()`は1です。
`i = 1`のとき：
- `array[1]`は`"B"`です。
- `"B".length()`は1です。
そのため、`j < array[i].length()`の条件は、それぞれの文字列の長さと`j`の値を比較しています。
### まとめ
- `array[i]`は配列の`i`番目の要素（文字列）を取得します。
- `array[i].length()`は、その文字列の長さを返します。
- この仕組みにより、配列の各要素（文字列）の長さに基づいてループの回数が決まります。 | aaattt | |

Outsourcing software development is an effective strategy that has gained significant traction. But what exactly are the benefits of outsourcing software, and why are so many businesses opting for it? This comprehensive guide explores the key advantages, backed by insights from industry experts.
## Cost Efficiency
One of the most compelling reasons to outsource software development is cost efficiency. Developing software in-house can be expensive, especially when considering the costs of hiring, training, and retaining skilled developers. Outsourcing allows businesses to leverage the expertise of external teams at a fraction of the cost. This cost advantage stems from lower labor costs in countries with a robust talent pool and favorable economic conditions.
For example, according to TatvaSoft, outsourcing can reduce operational costs by up to 60%. You can redirect this significant savings towards other critical business areas like marketing, research, and development.
## Access to Global Talent
Outsourcing opens up access to a vast pool of global talent. This means businesses are no longer limited by geographical boundaries when searching for skilled developers. Instead, they can tap into specialized expertise from around the world, ensuring they get the best possible talent for their projects.
Orient Software highlights that outsourcing provides access to experts who are well-versed in the latest technologies and industry trends. This access ensures that the software developed is cutting-edge and aligns with global standards.
## Focus on Core Competencies
By outsourcing software development, businesses can focus on their core competencies. This strategic delegation allows internal teams to concentrate on what they do best, whether it's marketing, customer service, or product development. Outsourcing partners handle the technical aspects, freeing up valuable time and resources.
Accelerance notes that this focus on core business activities can lead to increased productivity and better overall performance. The complexities of software development do not hinder companies' ability to innovate and grow.
## Faster Time-to-Market
Speed is crucial in today’s fast-paced market. Outsourcing can significantly accelerate the development process, ensuring that products reach the market faster. External teams often have the experience and resources to work more efficiently, adhering to tight deadlines without compromising on quality.
Uptech emphasizes that a faster time-to-market can be a decisive factor in gaining a competitive edge. Early entry into the market enables businesses to capture market share and respond more quickly to customer needs.
## Scalability and flexibility
Outsourcing offers unparalleled scalability and flexibility. Businesses can scale their development efforts up or down based on project requirements. This flexibility is particularly beneficial for startups and growing companies that need to adapt quickly to changing market conditions.
According to BlackBear, outsourcing partners can provide additional resources during peak times and scale back during slower periods. This dynamic approach ensures that businesses only pay for what they need, optimizing resource allocation.
## Risk Management
Outsourcing can help mitigate various risks associated with software development. Experienced outsourcing partners have established processes and best practices to handle potential challenges effectively. They are adept at managing risks related to project delays, technical issues, and budget overruns.
Accelerance points out that outsourcing partners often have contingency plans in place, ensuring that projects stay on track even in the face of unforeseen obstacles. This proactive risk management approach provides peace of mind to businesses.
## Access to the latest technologies
Keeping up with the rapid pace of technological advancements can be challenging. Outsourcing partners are typically at the forefront of technology, continuously updating their skills and tools. This access to the latest technologies ensures that the software developed is modern, efficient, and future-proof.
Orient Software emphasizes that outsourcing allows businesses to leverage cutting-edge technologies without the need for significant investments in training and infrastructure. This advantage can lead to more innovative and competitive software solutions.
## Improved Quality and Performance
Quality is a critical factor in software development. Reputable outsourcing partners adhere to stringent quality standards, employing best practices and rigorous testing methodologies. This focus on quality ensures that the software delivered is robust, reliable, and performs optimally.

## Continuous support and maintenance
Software development doesn’t end with deployment. Ongoing support and maintenance are crucial for ensuring that the software continues to function effectively. Outsourcing partners often provide comprehensive support services, including updates, bug fixes, and enhancements.
BlackBear notes that continuous support from outsourcing partners can lead to long-term reliability and user satisfaction. Businesses can rely on their partners to handle technical issues, allowing them to focus on strategic initiatives.
## Focused Innovation
Outsourcing can foster a culture of innovation within businesses. By partnering with experts who bring fresh perspectives and innovative ideas, companies can explore new opportunities and technologies. This collaboration can lead to the development of groundbreaking solutions that drive business growth.
According to TatvaSoft, outsourcing partners frequently have experience in a variety of industries, which allows them to offer insightful analysis and creative solutions that are applicable in a variety of business settings.
## Conclusion
Outsourcing software development offers numerous benefits that can drive business success.

1,867,487 | How to Write a Winning Re-engagement Email? | Re-engagement emails are a powerful tool for rekindling interest among subscribers who have become... | 0 | 2024-05-28T10:16:16 | https://dev.to/accuwebhosting/how-to-write-a-winning-re-engagement-email-2mp8 | email, marketing, howto, write | Re-engagement emails are a powerful tool for rekindling interest among subscribers who have become inactive. In today's fast-paced digital world, it's common for email lists to experience churn, with subscribers gradually losing interest and engagement over time. This can be frustrating for marketers who put a lot of effort into creating and sending emails, only to see open rates decline and conversions drop.
Inactive subscribers represent a valuable opportunity. They have already shown interest in your brand at some point, and with the right approach, you can reignite that interest and turn them back into active, engaged customers. Re-engagement emails can help you achieve this by reaching out to those who haven't interacted with your emails in a while, offering them compelling reasons to re-engage.
In this blog, we will cover the essential steps to write a winning re-engagement email.
## A Quick Tip
Before we start, a crucial aspect of maintaining a healthy email list is email verification, which ensures that your emails reach valid and active recipients, improving deliverability and engagement rates.
Email verification is essential for maintaining a clean and engaged subscriber list. By verifying the validity of email addresses, you can reduce bounce rates, prevent emails from being marked as spam, and improve overall deliverability. Additionally, [bulk email verification](https://www.accuwebhosting.com/blog/top-10-bulk-email-list-verification-validation-services-compared/) helps you maintain sender reputation and ensures that your emails reach the intended recipients, maximizing the effectiveness of your email marketing campaigns.
## Understand Your Inactive Subscribers
Before crafting an effective re-engagement email, it's essential to understand who your inactive subscribers are and why they've become inactive. Identifying and analyzing this group allows you to tailor your messaging and approach to meet their specific needs and preferences.
### Identifying Inactive Subscribers
Start by defining what "inactive" means for your email list. Typically, an inactive subscriber is someone who hasn’t opened or clicked on any of your emails within the last three to six months. Use your email marketing platform to segment these subscribers and isolate those who haven't engaged within this period. Analyzing engagement data can provide insights into their past behaviors and preferences, helping you understand what initially interested them.
### Reasons for Inactivity
Subscribers can become inactive for various reasons. Often, the content you’re sending might no longer be relevant to their interests or needs. The frequency of your emails can also impact engagement—sending too many emails can overwhelm subscribers, while sending too few can make them forget about your brand. Other factors include poor email timing, technical issues like emails landing in the spam folder, and lack of personalization. Understanding these reasons helps you address the issues and create a more effective re-engagement strategy.
## Craft an Attention-Grabbing Subject Line
The subject line is the first thing your subscribers see, and it plays a crucial role in determining whether they will open your email. An attention-grabbing subject line can make the difference between your email being ignored or read. Here’s how to create compelling subject lines that encourage opens.
### Tips for Effective Subject Lines
Keep your subject lines short and to the point, ideally under 50 characters. Use language that creates curiosity or urgency, such as "We Miss You! Exclusive Offer Inside" or "Last Chance to Reconnect with Us." Personalize the subject line by including the recipient’s name or referencing their past behavior, like "John, We’ve Got Something Special Just for You!"
## Personalize Your Email Content
Personalization is a key factor in making your re-engagement emails stand out. When subscribers receive emails that feel tailored to their interests and preferences, they are more likely to engage with the content. Here’s how to personalize your email content effectively.
### Using Recipient’s Name and Preferences
Start by addressing the recipient by their name. This simple touch can make the email feel more personal and engaging. Go beyond just the name—use data on their past behaviors and preferences to tailor the content. For instance, reference past purchases or content they've shown interest in. A personalized email might say, "Hi Sarah, we noticed you enjoyed our summer collection. Here’s a special offer on our new arrivals just for you."
### Tailoring Content Based on Behavior
Segment your inactive subscribers based on their past interactions with your emails or website. Create content that speaks directly to these segments. For example, if a subscriber frequently clicked on articles about a specific topic, include similar content in your re-engagement email. Highlight products, services, or information that align with their interests. This approach shows that you understand their needs and are providing relevant value.
## Provide Value and Incentives
To re-engage inactive subscribers, you need to offer them something valuable that piques their interest. Providing value and incentives can motivate them to open your emails and take action.
### Offering Discounts or Special Offers
One of the most effective ways to re-engage subscribers is by offering them exclusive discounts or special offers. A subject line like "We Miss You! Enjoy 20% Off Your Next Purchase" can grab attention and entice them to open the email. Inside, clearly state the offer and how to redeem it. Limited-time offers create a sense of urgency, encouraging subscribers to act quickly.
### Sharing Valuable Content
Not all incentives have to be monetary. Sometimes, sharing valuable content that addresses the subscribers' interests or needs can be just as effective. This could be in the form of a helpful blog post, an exclusive guide, or early access to new content or products. For instance, "Welcome Back! Here’s an Exclusive Guide Just for You" can attract those who value insightful content. Ensure the content is relevant and provides real value to your subscribers.
## Create a Clear and Compelling Call to Action (CTA)
A clear and compelling call to action (CTA) is essential for encouraging your inactive subscribers to take the next step. The CTA is what drives the action you want them to take, whether it's making a purchase, reading a blog post, or updating their preferences.
### Designing Effective CTAs
Your CTA should be straightforward and easy to understand. Use action-oriented language that clearly communicates what you want the subscriber to do. Phrases like "Shop Now," "Get Your Discount," or "Read More" are direct and effective. Ensure that the CTA stands out visually by using contrasting colors and placing it in a prominent position within the email.
### Placement and Frequency of CTAs
The placement of your CTA can significantly impact its effectiveness. Position your primary CTA above the fold, where it's immediately visible without scrolling. If your email is longer, include additional CTAs throughout the content to remind readers of the desired action. However, avoid overwhelming your subscribers with too many CTAs, which can dilute the message. One to three strategically placed CTAs are usually sufficient.
A clear and compelling CTA guides your subscribers towards taking the desired action, making it a crucial element in your re-engagement emails. By designing effective CTAs and strategically placing them within your email, you can increase the likelihood of your inactive subscribers re-engaging with your content and brand.
## Conclusion
From understanding why subscribers become inactive to crafting attention-grabbing subject lines and personalized content, we have provided practical tips and strategies to help you reconnect with your audience. By following these guidelines, you can create re-engagement emails that not only capture your subscribers' attention but also encourage them to re-engage with your brand. | clay_p |

1,867,485 | Apache OpenServerless project | Hello everyone, we are happy to announce that we submitted the OpenServerless project to the Apache... | 0 | 2024-05-28T10:15:39 | https://dev.to/nuvolaris/apache-openserverless-project-81o | Hello everyone, we are happy to announce that we submitted the OpenServerless project to the Apache Software Foundation. We are going to develop our Nuvolaris Community into a worldwide open source project at the highest level.
The goal is to provide the open source foundation of our Nuvolaris Enterprise
product as a vendor independent and stable project maintained by a community.
To achieve this goal, we have submitted the Apache OpenServerless proposal is the natual step. The link to the proposal can be found here:
https://cwiki.apache.org/confluence/display/INCUBATOR/OpenServerlessProposal
Our codebase is well tested and already has a number of paying and open source customers. We already have a network of contributors who have already contributed to the codebase and we have found the mentors for our project and the champion for the project.
But what is the Nuvolaris community (to become Apache OpenServerless)? There is already an open source serverless engine (Apache OpenWhisk) and I am one of the PMC of the project and also wrote an O'Reilly book about it: Learning Apache OpenWhisk.
What is missing now is a complete distribution including integrated services to build a complete platform. We want the Apache OpenServerless project to fill this gap.
With Nuvolaris Community we provide storage, databases, caches, frontend, IDE, starters and even LLM support on top of OpenWhisk. We have made this available and running on all major cloud provider Kubernetes platforms (EKS, AKS, GKE, LKE) and also for the Kubernetes of all major Linux distributions (RedHat OpenShift, Ubuntu MicroK8S, SuSE K3S).
Simply put, if OpenWhisk is Linux, then Nuvolaris is RedHat. The OpenServerless project aims to be the first complete open source distribution that makes it easy to build cloud-native applications with portability in mind.
And we want to build the platform in the open, contributing our work to the Apache Software Foundation to make it widely available and get more vendors involved in supporting it. | nuvolaris | |

564,023 | Data for World Map Panel Plugin in Grafana from MySQL | Data for World Map Panel Plugin in Grafana: Approach 1: Using the InfluxDB data: Here, the data... | 0 | 2024-05-28T10:09:07 | https://dev.to/krishnakurtakoti/data-for-world-map-panel-plugin-in-grafana-from-mysql-5ggh | mysql, grafana, sql, visualization | Data for World Map Panel Plugin in Grafana:
Approach 1:
Using the InfluxDB data:
1. Here, the data is pulled from the database(InfluxDB) from a single measurement(table).
Schema of the hdb7 table is:
| Time | DS_ID | from | graphStatement | latitude | longitude | to | totalPower | value |
| -----|:-----:| --: | -------------: | -------: | -------: | --:|-----------:|------:|
The above is the data that is pushed to the measurement(hdb7) of the InfluxDB database. Here, the hdb7 table’s graphStatement field values will be shown on the world map.
Query:
SELECT * from "hdb7" GROUP BY * ORDER BY DESC LIMIT 4
| col1 | col2 |
| --------------| ------:|
| Location Data | table |
| Aggregation | current|
Map Data Options
Field Mapping
| col1 | col2 |
| --------------------| -------------: |
| Table Query Format | coordinates |
|Location Name Field | graphStatement |
| Metric Field | value |
| Latitude Field | latitude |
| Longitude Field | longitude |
Field Mapping
DrawBack:
1.
The requirement specifically mentions having 2 tables like shown below.
JOIN statements are not supported in InfluxDB.
Table1
DS_ID, Lat, Long
Table2
DS_ID, Sum(pump),sum(light),..total value
Table1:
| DS_ID | latitude | longitude | value | time |
| ------| --------:| ----------:|------:|-----:|
Table2:
| DS_ID | graphStatement | totalPower | value | time |
| ------| --------------:| ----------:|------:|-----:|
The graphStatement covers the fields sum(boosterPump), sum(lighting), sum(lift) which are to be displayed on the map.
“JOIN is no longer a concept in 0.9. Series sharing a measurement can be queried together simply by omitting the differentiating tags from the WHERE clause.”
Link:
https://github.com/influxdata/influxdb/issues/624
However, there is one alternative called transformations in Grafana that can be used to join 2 tables of same datasource/mixed datasource as shown below.
Here, the data for Table1 (DS_ID, Lat, Long) will be queried from MySQL database. The data for Table2 (DS_ID, Sum(pump),sum(light),..total value) will be queried from InfluxDB database.
**Implementation:**
1. We can implement the above by choosing the datasource as Mixed.
The query 1 will be:
**SELECT * from hdb10**

1,867,474 | Efficiently Batch Writing Documents in Firestore with Next.js | Learn how to implement batch writing of documents in Firestore within a Next.js API route to optimize data handling and improve performance. | 0 | 2024-05-28T10:00:48 | https://dev.to/itselftools/efficiently-batch-writing-documents-in-firestore-with-nextjs-171o | firebase, nextjs, api, javascript |
In the fast-evolving world of web development, optimizing data handling processes is crucial for performance and scalability. Today, we're discussing a powerful approach to managing data with Firestore within a Next.js environment. At [itselftools.com](https://itselftools.com), we've developed over 30 projects using Next.js and Firebase, and have gained valuable insights that we are eager to share with you.
## Understanding the Code
Here is a brief explanation of what the provided Node.js code does when integrated into a Next.js API route:
```javascript
// 7. API Route to batch write multiple documents in Firestore
const { db } = require('../../firebase');
export default async function handler(req, res) {
if (req.method === 'POST') {
const users = req.body;
try {
const batch = db.batch();
users.forEach(user => {
const docRef = db.collection('users').doc();
batch.set(docRef, user);
});
await batch.commit();
res.status(200).json({ message: 'Batch write successful' });
} catch (e) {
res.status(400).json({ message: 'Batch write failed' });
}
} else {
res.setHeader('Allow', ['POST']);
res.status(405).end(`Method ${req.method} Not Allowed`);
}
}
```
### Step-by-Step Breakdown
1. **Check Request Method**: The server checks if the incoming request is a POST. If not, it rejects the request with a 405 Method Not Allowed status.
2. **Create a Batch Object**: A batch object is created using `db.batch()`, allowing multiple writes to be grouped into a single transaction.
3. **Document References and Write Operations**: For each user in the request body, a new document reference in the 'users' collection is created. Each user's data is then written to their respective document through the `batch.set()` method.
4. **Commit the Batch**: The batch of writes is committed asynchronously using `await batch.commit()`. If successful, the operation returns a status of 200, indicating a successful batch write.
5. **Error Handling**: In the event of an exception (e.g., a failed write operation), the server responds with a status of 400 and an explanatory message.
## Why Use Batch Writing?
Batch writing is an efficient way to write multiple documents to Firestore simultaneously. This method reduces network requests, minimizes write operation overhead, and significantly enhances performance, especially when dealing with large sets of data.
## Conclusion
Leveraging batch writes in Firestore within your Next.js applications can lead to more efficient, reliable, and scalable data handling.

1,866,377 | Herramientas SSDLC: SAST, DAST y SCA | El Ciclo de Vida de Desarrollo Seguro de Software (SSDLC) representa un conjunto de actividades... | 0 | 2024-05-28T10:00:00 | https://dev.to/rodri-oliveira-dev/herramientas-ssdlc-sast-dast-y-sca-7ja | ssdlc, sast, dast | El Ciclo de Vida de Desarrollo Seguro de Software (SSDLC) representa un conjunto de actividades realizadas durante el desarrollo de software, enfocándose en la inclusión de medidas de seguridad en todas las etapas del desarrollo. Entre las herramientas utilizadas para este fin, se destacan la Análisis Estática de Seguridad de Aplicaciones (SAST), la Análisis Dinámica de Seguridad de Aplicaciones (DAST) y la Análisis de Composición de Software (SCA). Vamos a discutir cada una de estas herramientas, considerando sus ventajas y limitaciones.
**SAST (Static Application Security Testing)**
**Ventajas**
SAST es una técnica que evalúa el código fuente de una aplicación en busca de vulnerabilidades de seguridad. Se realiza sin ejecutar el código, por eso se llama "estática".
1. **Detección temprana de vulnerabilidades:** Como SAST evalúa el código fuente, es posible detectar las vulnerabilidades desde el inicio del ciclo de desarrollo, permitiendo la corrección inmediata de los problemas.
2. **Integración con el entorno de desarrollo:** Muchas herramientas SAST pueden integrarse directamente con los entornos de desarrollo (IDEs), facilitando el proceso de verificación del código.
**Limitaciones**
1. **Falsos positivos:** Las herramientas SAST pueden generar un número significativo de falsos positivos, lo que significa que el tiempo de revisión y corrección puede ser mayor.
2. **Dificultad para manejar el código en tiempo de ejecución:** SAST no puede detectar problemas que solo aparecen durante la ejecución del programa, como fallos de configuración.
**DAST (Dynamic Application Security Testing)**
**Ventajas**
DAST es una técnica que evalúa una aplicación en ejecución en busca de vulnerabilidades de seguridad. Es una técnica "caja negra" que no requiere acceso al código fuente de la aplicación.
1. **Detección de fallos en tiempo de ejecución:** A diferencia de SAST, DAST es capaz de detectar fallos que solo se manifiestan durante la ejecución del programa.
2. **No requiere acceso al código fuente:** Como es una técnica de "caja negra", DAST puede utilizarse incluso sin acceso al código fuente de la aplicación.
**Limitaciones**
1. **No detecta vulnerabilidades en el código fuente:** DAST puede no detectar algunas vulnerabilidades que existen en el código fuente.
2. **Más lenta que SAST:** Como DAST prueba la aplicación en ejecución, generalmente es más lenta que SAST.
**SCA (Software Composition Analysis)**
**Ventajas**
SCA es una técnica que evalúa los componentes del software, como bibliotecas y módulos de terceros, en busca de vulnerabilidades de seguridad.
1. **Identificación de componentes inseguros:** SCA permite identificar componentes de software que pueden representar riesgos de seguridad, permitiendo su sustitución o actualización.
2. **Monitoreo continuo:** Muchas herramientas SCA ofrecen monitoreo continuo, permitiendo que se detecten nuevas vulnerabilidades tan pronto como se vuelven conocidas.
**Limitaciones**
1. **Dependencia de bases de datos de vulnerabilidades:** La eficacia de SCA depende de la calidad y actualización de las bases de datos de vulnerabilidades utilizadas.
2. **No detecta problemas en el código personalizado:** SCA está enfocada en componentes de terceros, y no en el código personalizado desarrollado por el equipo.
**Herramientas SAST (Static Application Security Testing)**
1. **SonarQube:** Una plataforma de código abierto utilizada para la inspección continua de la calidad del código y detección de errores, vulnerabilidades de código y malos olores de código.
2. **Checkmarx:** Herramienta comercial que ofrece soporte a una amplia variedad de lenguajes de programación e integración con IDEs populares.
3. **Fortify:** Producto de Micro Focus, Fortify ofrece soluciones SAST para detectar vulnerabilidades de seguridad en el código fuente.
4. **Veracode Static Analysis:** Otra herramienta comercial que ofrece análisis estático de código para identificar vulnerabilidades de seguridad.
**Herramientas DAST (Dynamic Application Security Testing)**
1. **OWASP ZAP (Zed Attack Proxy):** Herramienta de código abierto para encontrar vulnerabilidades de seguridad en aplicaciones web durante el desarrollo y prueba.
2. **Nessus:** Producto comercial de Tenable, es una de las herramientas de escaneo de vulnerabilidades más conocidas y utilizadas.
3. **Acunetix:** Herramienta de prueba de penetración enfocada en aplicaciones web. Ofrece análisis DAST automatizado.
4. **Burp Suite:** Producto de PortSwigger, ampliamente utilizado para pruebas de penetración en aplicaciones web.
**Herramientas SCA (Software Composition Analysis)**
1. **WhiteSource:** Ofrece gestión de vulnerabilidades y licencias de código abierto, y puede integrarse en todo el SSDLC.
2. **Snyk:** Se enfoca en la seguridad de código abierto y puede detectar vulnerabilidades en bibliotecas de código abierto.
3. **Black Duck:** Producto de Synopsys, ayuda a gestionar riesgos asociados a componentes de código abierto.
4. **JFrog Xray:** Una herramienta de análisis universal que soporta varios lenguajes y tipos de paquetes, ofreciendo visibilidad continua de seguridad y licencia.
**Conclusión**
La adopción de herramientas como SAST, DAST y SCA es esencial para garantizar la seguridad en el ciclo de vida de desarrollo de software (SSDLC). Cada una de ellas desempeña un papel crítico en la identificación de vulnerabilidades, ya sea en el código fuente, durante la ejecución de la aplicación o en los componentes de terceros utilizados en el software.
Sin embargo, es importante recordar que cada una de estas herramientas tiene sus limitaciones y no debe utilizarse de forma aislada como una solución completa para la seguridad del software. La combinación de estos enfoques ofrece una estrategia de seguridad más robusta y completa.
Además, la elección de la herramienta adecuada depende de varios factores, incluyendo los lenguajes de programación utilizados, la naturaleza del proyecto y el entorno de desarrollo. Independientemente de la herramienta elegida, el objetivo final es integrar la seguridad en todas las fases del ciclo de vida del desarrollo de software, en lugar de tratarla como una consideración posterior.
Finalmente, es crucial recordar que las herramientas son solo una parte de la solución. Una cultura de seguridad, un equipo bien entrenado y procesos bien definidos son igualmente importantes para garantizar la seguridad del software. Las herramientas pueden ayudar a detectar y corregir problemas, pero la prevención de vulnerabilidades comienza con la práctica de buenos hábitos de programación y un enfoque de diseño de seguridad desde el inicio. | rodri-oliveira-dev |
1,864,675 | Performance Tuning in React Applications: Best Practices and Examples | React has revolutionized the way we build user interfaces, offering a component-based architecture... | 0 | 2024-05-28T09:59:00 | https://dev.to/nitin-rachabathuni/performance-tuning-in-react-applications-best-practices-and-examples-2893 | React has revolutionized the way we build user interfaces, offering a component-based architecture that promotes reusability and maintainability. However, as applications grow, performance can become an issue. This article dives into effective strategies for performance tuning in React applications, with practical coding examples to illustrate each point.
1. Leveraging React’s Pure Components
Pure Components optimize rendering by implementing a shallow comparison on props and state changes. This prevents unnecessary re-renders of child components when their props haven’t changed.
Example:
```
import React, { PureComponent } from 'react';
class MyComponent extends PureComponent {
render() {
console.log('Rendered!');
return <div>{this.props.text}</div>;
}
}
// Usage
<MyComponent text="Hello World" />
```
In this example, MyComponent only re-renders if text prop changes, improving performance.
2. Using React.memo for Functional Components
React.memo is a higher-order component that memoizes the rendered output of functional components, providing a similar performance boost as PureComponent.
Example:
```
import React from 'react';
const MyComponent = React.memo(({ text }) => {
console.log('Rendered!');
return <div>{text}</div>;
});
// Usage
<MyComponent text="Hello World" />
```
MyComponent will only re-render if text prop changes, thanks to React.memo.
3. Optimizing State Management
Avoid unnecessary re-renders by managing state at the appropriate level. Moving state up or down the component tree can significantly impact performance.
Example:
```
import React, { useState } from 'react';
const ParentComponent = () => {
const [parentState, setParentState] = useState('Parent State');
return (
<>
<button onClick={() => setParentState('Updated Parent State')}>
Update Parent State
</button>
<ChildComponent childState="Child State" />
</>
);
};
const ChildComponent = React.memo(({ childState }) => {
console.log('Child Rendered!');
return <div>{childState}</div>;
});
```
Here, ChildComponent won’t re-render when parentState updates because its props haven’t changed.
4. Implementing Code Splitting
Code splitting with React.lazy and Suspense can significantly reduce the initial load time by splitting your code into manageable chunks.
Example:
```
import React, { Suspense } from 'react';
const LazyComponent = React.lazy(() => import('./LazyComponent'));
const App = () => (
<div>
<Suspense fallback={<div>Loading...</div>}>
<LazyComponent />
</Suspense>
</div>
);
```
By loading LazyComponent only when needed, the initial bundle size is reduced, enhancing load performance.
5. Avoiding Inline Functions in Render Methods
Defining functions inside render methods can cause performance issues as new instances of these functions are created on every render.
Example:
```
import React, { useCallback } from 'react';
const MyComponent = ({ onClick }) => {
console.log('Rendered!');
return <button onClick={onClick}>Click Me</button>;
};
const ParentComponent = () => {
const handleClick = useCallback(() => {
console.log('Button clicked!');
}, []);
return <MyComponent onClick={handleClick} />;
};
```
Using useCallback ensures handleClick remains stable across renders, preventing unnecessary re-renders of MyComponent.
6. Using the React Profiler
React Profiler helps identify performance bottlenecks in your application by measuring the rendering time of components.
Example:
```
import React, { Profiler } from 'react';
const onRenderCallback = (id, phase, actualDuration) => {
console.log(`${id} ${phase} ${actualDuration}`);
};
const App = () => (
<Profiler id="App" onRenderCallback={onRenderCallback}>
<MyComponent />
</Profiler>
);
```
The Profiler component logs rendering times, helping developers focus on optimizing the most time-consuming parts of their applications.
Conclusion
Performance tuning in React applications is crucial for providing a smooth user experience. By leveraging Pure Components, React.memo, proper state management, code splitting, avoiding inline functions, and using the React Profiler, developers can significantly enhance the performance of their applications. Start incorporating these techniques today to ensure your React apps run efficiently and effectively.

1,867,473 | Contours on MYSQL Aurora Database with Blue/Green Deployment and Switch Over | “ I have checked the documents of AWS to get into a contours on mysql aurora database with blue/green... | 0 | 2024-05-28T09:56:37 | https://dev.to/aws-builders/contours-on-mysql-aurora-database-with-bluegreen-deployment-and-switch-over-3i7k | aws, amazonrds, cloudwatch, bluegreendeployment | “ I have checked the documents of AWS to get into a contours on mysql aurora database with blue/green deployment and switch over. In terms of cost, need to pay for amazon rds and cloudwatch.”
Amazon Aurora is a fully managed relational database engine that's compatible with Mysql and Postgresql. As already know how mysql and postgresql combine the speed and reliability of high end commercial databases with the simplicity and cost effectiveness of open source databases.
When you create a blue/green deployment, you specify the DB cluster to copy in the deployment. The DB cluster you choose is the production DB cluster and it becomes the DB cluster in the blue environment. RDS copies the blue environment's topology to a staging area, along with its configured features. The db cluster is copied to the green environment and rds configures replication from the db cluster in the blue environment to the db cluster in the green environment. RDS also copies all of the db instances in the db cluster.
A switchover promoted the db cluster, including its db instances, in the green environment to be the production db cluster. Before you switch over, production traffic is routed to the cluster in the blue environment. After you switch over production traffic is routed to the db cluster in the green environment.
In this post, you will experience how to contours on mysql aurora database with blue/green deployment and switch over. Here I have created an amazon rds mysql aurora database with a custom db parameter group and blue/green deployment. Also the addition of a switch over feature on aurora database.
#Architecture Overview
The architecture diagram shows the overall deployment architecture with data flow, amazon rds mysql aurora, cloudwatch, blue/green deployment.
#Solution overview
The blog post consists of the following phases:
1.Create of Amazon RDS Mysql Aurora with Custom DB Cluster Parameter Group
2.Create of Blue/Green Deployment on Aurora RDS
3.Output of Blue/Green Deployment with Switch Over Option
##Phase 1: Create of Amazon RDS Mysql Aurora with Custom DB Cluster Parameter Group
1. Open the console of Amazon RDS, create a db cluster parameter group. Update the value of binlog_format as ROW in the parameter group. Create aurora mysql rds with a custom db cluster parameter group.
##Phase 2: Create of Blue/Green Deployment on Aurora RDS
1. Select the database and choose the blue/green deployment option from action drop down. Start creating the deployment as a staging environment with specifying identifiers and other required parameters.
##Phase 3: Output of Blue/Green Deployment with Switch Over Option
#Clean-up
Delete of Amazon RDS, DB Cluster Parameter Group and Cloudwatch Log Group.
#Pricing
I review the pricing and estimated cost of this example.

While working with the... | 0 | 2024-05-28T09:56:28 | https://dev.to/workodoro/solving-the-radix-integration-issue-in-nextjs-4cme | nextjs, radix, webdev, buildinpublic | I am Leo Hoang. Currently, I am working on my next startup project: Workodoro. While working with the Workodoro application, I encountered an issue integrating Radix into Next.js.
From version 13.0 to 14.1, Next.js has an issue with the import order of CSS files in app/**/layout.tsx. This can result in Radix Themes overwriting your custom styles, even when the import statements are correctly structured:
```javascript
import '@radix-ui/themes/styles.css';
import './my-styles.css';
```
This problem can occur sporadically, affecting either development or production environments, leading to inconsistencies. Fortunately, there are effective solutions to ensure your styles are applied as intended.
### Solution
**Merging CSS Files with postcss-import**
The most reliable method is to merge all CSS into a single file using the postcss-import plugin. This approach ensures a consistent import order by consolidating all your styles into one unified file.
#### Step-by-Step Guide:
**1. Install postcss-import:** First, install the postcss-import plugin:
```bash
npm install postcss-import
```
**2. Configure postcss.config.js:** Add postcss-import to your postcss.config.js file:
```javascript
module.exports = {
plugins: {
"postcss-import": {},
tailwindcss: {},
autoprefixer: {},
},
};
```
**3. Update Your CSS File:** Import Tailwind's base styles first, followed by Radix Themes, and then your components and utilities:
```css
@import "tailwindcss/base";
@import "@radix-ui/themes/styles.css";
@tailwind components;
@tailwind utilities;
```
This setup ensures that Tailwind’s base styles load first, followed by Radix Themes, and then your custom components and utilities, maintaining a proper and predictable order.
### Conclusion
These brief notes hope to help someone facing a similar issue save time.

1,867,267 | Configure Email Clients | This part will guide you on how to configure email clients, such as Mozilla Thunderbird, Apple Mail,... | 26,986 | 2024-05-28T09:50:35 | https://dev.to/budiantoip/configure-email-clients-43f2 | email, exim, almalinux | This part will guide you on how to configure email clients, such as [Mozilla Thunderbird](https://www.thunderbird.net/en-US/), [Apple Mail](https://www.icloud.com/mail), and [Microsoft Outlook](https://www.microsoft.com/en-us/microsoft-365/outlook/email-and-calendar-software-microsoft-outlook). Further details will be explained in each section.
## IMAP or POP
Before we begin, since we will be presented with the option to choose between IMAP and POP when configuring mail clients, let us review the differences between the two.
### IMAP
#### Server-Based Storage
- Emails are stored on the mail server and synchronized across all devices.
- Actions like reading, deleting, or organizing emails are mirrored on all devices.
#### Accessibility:
- Allows access to email from multiple devices (computers, smartphones, tablets) while keeping everything synchronized.
- Ideal for users who check their email from various locations or devices.
#### Real-Time Updates:
- Changes made in the mail client are reflected immediately on the server and other devices.
- Supports folder organization and maintains the structure across devices.
#### Offline Access:
- You can choose to download emails for offline access, but changes made offline will be updated on the server once reconnected.
#### Space Management:
- Email is stored on the server, potentially occupying server space if not managed properly.
- Typically used by those with large mail quotas or those who manage emails regularly.
### POP
#### Local Storage:
- Emails are downloaded from the server to a single device and typically deleted from the server (though some settings allow copies to remain on the server).
- Actions on one device (like deleting or moving emails) do not affect other devices.
#### Single-Device Focus:
- Best suited for users who access their email from one device.
- Less suitable for multi-device access since synchronization across devices is not inherently supported.
#### Offline Access:
- Since emails are downloaded and stored locally, they are accessible offline.
- Changes made (like organizing or deleting emails) are local to that device only.
#### Space Management:
- Frees up server space since emails are typically removed from the server after download.
- Useful for users with limited server storage or who prefer keeping a local archive.
### Which One to Choose?
- IMAP is generally recommended if you:
- Access your email from multiple devices.
- Want real-time synchronization of your email and folders across all devices.
- Prefer server-based storage and management of your emails.
- POP might be suitable if you:
- Mainly access your email from a single device.
- Prefer to download and store emails locally.
- Want to minimize server storage usage.

Proxy pattern has a lot of... | 21,253 | 2024-05-28T09:37:39 | https://dev.to/jzfrank/hfdp11-proxy-pattern-4ef8 | Proxy manages and controls access. Proxy is a stand in for a real object. Proxy pattern has a lot of variations.
For example, if we want to call a method of an object living remotely in another JVM, we need to make use of the Remote Proxy. In java, we could achieve this by using `rmi` technology. Basically, the client calls a stub that implements the same Remote interface as the real subject. The stub then forwards the request to the skeleton living in the JVM, which then calls the real subject and forwards back returned value. Through the time, the client thinks it is accessing the real subject, which it is not doing this directly.
Another well-known example is the Virtual Proxy. It is used for wrapping an expensive object like an image fetched from a network. Let's say you want to display an image on screen. Instead of fetching the image and manages the waiting yourself, you could delegate the task to a virtual proxy. It will fire a thread to fetch the image, and renders waiting texts while waiting. In this manner, you reduced the coupling in code.
We may also need to manage access, which brings the Protection Proxy. It wraps an object and decides if the client could access certain methods of it. In Java it is implemented via reflection. e.g.
```java
Person getOwnerProxy(Person, person) {
return (Person) Proxy.newProxyInstance(
person.getClass().getClassLoader(),
person.getClass().getInterfaces(),
new OwnerIncovationHandler(person));
}
```
where `OwnerIncovationHandler` implements `InvocationHandler`. Its method signature is `Object invoke(Object proxy, Method method, Object[] args)`.
We've seen a number of patterns that serve as wrapper. They look similar but serves different purposes:
- Decorator Pattern: wrap an object add behaviors
- Facade Pattern: wrap possible many objects and simplify interfaces
- Adapter Pattern: wraps an object and implements another interface
- Proxy Pattern: wraps an object and controls access.
Proxy pattern has many variations:
- Firewall Proxy (control access to network recourses) -> e.g. corporate firewall system.
- Smart Reference Proxy (provide additional actions when a subject is referenced e.g. count)
- Caching Proxy (temp store expensive resources) -> web server proxies and content management and publishing systems.
- Synchronization Proxy (provides safe access to a subject from multiple threads)
- Complexity Hiding Proxy (pretty much like Facade)
- Copy-on-Write Proxy (lazy copying, variant of Virtual Proxy)

A mobile app development checklist acts as your GPS, ensuring you don't miss any crucial steps and keeping your project focused and efficient. Here, we'll break down the key stages of mobile app development and provide essential checklists for each phase.
**1. Planning and Discovery: Charting Your Course**
Before coding, you need to lay the groundwork for your app's success. The planning and discovery phase helps you define your app's identity, target users, and set realistic goals. Here's what to focus on:
Know Your Why: Identify the problem your app solves and the value it brings to users. Clearly define your app's core purpose and unique selling proposition (USP).
Identify Your Audience: Understand your ideal user, including their demographics, tech habits, and pain points. Craft a user experience that resonates with them.
Competitive Analysis: Research your competitors to understand their strengths and weaknesses. Identify gaps in the market that your app can fill.
Platform Choice: Decide whether to target iOS, Android, or both. Consider your audience's device preferences and development costs.
Budgeting and Scheduling: Estimate costs for development, design, and marketing. Set achievable deadlines for each project stage to stay on track.
**2. Design and User Experience (UX)**
Creating a user-friendly design is crucial. Here's how to ensure your app looks good and works well:
Understand Your Users: Develop detailed user personas that represent your ideal users, outlining their demographics, goals, and pain points.
Wireframes & Prototypes: Start with low-fidelity wireframes to map out the app's screens and functionality. Then, create interactive prototypes to test the app flow and gather feedback.
UI Design: Focus on a visually appealing and intuitive user interface. Ensure clear layouts, easy-to-find buttons, and a design that reflects your brand identity.
**3.Development**
Efficient development is key to bringing your app to life. Here's how to approach it:
Native vs. Cross-Platform Development: Decide whether to build separate apps for iOS and Android (native) or use a cross-platform framework.
App Features: Choose a tech stack based on the complexity of your app's features. A simple app might use different languages than a graphically demanding game.
Developer Expertise: Select a tech stack your development team is comfortable with to ensure efficient development.
Development Process:
Coding Standards: Establish conventions for naming variables, formatting code, and commenting to improve code readability.
Development Methodology: Consider Agile for iterative development, testing, and feedback loops to adapt to changes and deliver a high-quality product.
Version Control System: Use a [VCS](https://www.vcsedu.org/) like Git to track changes, collaborate, and maintain a clear development history.
**4. Testing and Quality Assurance (QA)**
Ensure your app functions flawlessly and delivers a great user experience:
Functionality Testing: Test every feature thoroughly to identify and fix bugs.
Performance Testing: Check how well your app performs on different devices and network connections. Optimize for smooth performance.
Usability Testing: Gather user feedback to identify and fix any clunky interfaces or confusing features. Ensure a user-friendly experience.
**5. Launch and Takeoff: Keeping Your App Soaring**
After polishing your app, it's time to launch and ensure its long-term success:
App Store Optimization (ASO): Create an enticing app store listing with compelling descriptions, relevant keywords, and captivating screenshots to attract users.
Marketing and User Acquisition: Generate pre-launch buzz with social media campaigns, influencer partnerships, or targeted advertising. Continue marketing efforts post-launch to attract and retain users.
Analytics and Maintenance: Monitor user behavior and app performance through analytics. Use this data to improve and optimize the user experience. Address bugs and issues proactively to keep your app running smoothly.
Remember, this checklist is a starting point. Adapt it to your specific project needs and resources. With a comprehensive checklist in hand, you'll be well-equipped to navigate the exciting world of mobile app development and bring your innovative idea to life.

title: Querying for Azure Regional Pairs
published: true
tags: azure
canonical_url: https://larryclaman.github.io/post/2020-04-09-querying-for-azure-regional-pairs/
---
A teammate recently posted a question on our Team's channel, asking how to programmatically query to find out an Azure Region's pair. Easy I thought - except it turns out, this isn't exposed in the standard PowerShell commands, nor in the Azure CLI.
The PowerShell command **Get-AzLocation** only returns the Location, DisplayName, and Providers:
```
PS C:\> Get-AzLocation|ft
Location DisplayName Providers
-------- ----------- ---------
eastasia East Asia {Microsoft.Media, Microsoft.HDInsight, Microsoft.SqlVirtualMachine, Microsoft.DevOps...}
southeastasia Southeast Asia {Microsoft.Media, Microsoft.HDInsight, Microsoft.DataShare, Microsoft.SqlVirtualMachine...}
centralus Central US {Microsoft.Media, Microsoft.HDInsight, Microsoft.SqlVirtualMachine, Microsoft.DevOps...}
eastus East US {Microsoft.Media, Microsoft.HDInsight, Microsoft.DataShare, Microsoft.SqlVirtualMachine...}
[snip]
```
Meanwhile, the Azure CLI returns more info, but not the pair:
```
PS C:\> az account list-locations
DisplayName Latitude Longitude Name
-------------------- ---------- ----------- ------------------
East Asia 22.267 114.188 eastasia
Southeast Asia 1.283 103.833 southeastasia
Central US 41.5908 -93.6208 centralus
East US 37.3719 -79.8164 eastus
East US 2 36.6681 -78.3889 eastus2
West US 37.783 -122.417 westus
[snip]
```
All hope is not lost! You can find the region's pair, but you need to query the Azure REST api directly, as documented at https://docs.microsoft.com/en-us/rest/api/resources/Subscriptions/ListLocations. In the past, you'd need to fire up your favorite REST client (eg, [armclient](https://github.com/projectkudu/ARMClient), Vscode + [rest client extension](https://marketplace.visualstudio.com/items?itemName=humao.rest-client), Postman, etc), but in exploring this, I learned an easier way: You can now make Azure REST calls directly from the CLI! Here's what that looks like: _(Replace {yoursubid} with your specific subscription id)_
```
az rest --method GET --uri https://management.azure.com/subscriptions/{yoursubid}/locations?api-version=2020-01-01 --output json
{
"value": [
{
"displayName": "East US",
"id": "/subscriptions/{yoursubid}/locations/eastus",
"metadata": {
"geographyGroup": "US",
"latitude": "37.3719",
"longitude": "-79.8164",
"pairedRegion": [
{
"id": "/subscriptions/{yoursubid}/locations/westus",
"name": "westus"
}
],
"physicalLocation": "Virginia",
"regionCategory": "Recommended",
"regionType": "Physical"
},
"name": "eastus",
"regionalDisplayName": "(US) East US"
},
[snip]
```
What's really cool is you can use the CLI's built-in jmespath query engine to filter and massage the results, eg: _(Column1 is the region, and Column2 is the pair)_
```
az rest --method GET --uri https://management.azure.com/subscriptions/{yoursubid}/locations?api-version=2020-01-01 --output table --query 'value[].[name,metadata.pairedRegion[].name]'
Column1 Column2
------------------- ----------------------
eastus ['westus']
eastus2 ['centralus']
southcentralus ['northcentralus']
westus2 ['westcentralus']
australiaeast ['australiasoutheast']
[snip]
```
(I'm still working on my jmespath ninja skills, so there's still a little cleanup to be done on this table, but it gets the point across.) | larryclaman |

However, the... | 0 | 2024-05-28T09:44:07 | https://dev.to/advancells/understanding-dyslexia-in-children-indicators-diagnosis-and-effective-support-4h23 | Parents often misconstrue dyslexia as an excuse crafted by children to evade studying. However, the reality is far deeper than being a reading difficulty. Dyslexia is a condition that impacts how the brain processes written and spoken language. Despite struggles with reading, writing and comprehension skills, individuals with dyslexia often exhibit strengths in problem solving and creativity.
Detecting signs of dyslexia in children plays a role, in nurturing their growth and helping them unleash their potential. Here are some common signs to be aware of;
- Struggling to learn words and sounds
- development of language skills
- Difficulties, with reading, spelling and writing fluently
- Trouble distinguishing left from right
- Issues with remembering sequences and following instructions accurately
- Skimming over or misinterpreting words
The causes of dyslexia can vary from person to person. While some individuals may exhibit one symptom others may display two or three. Dyslexia is a condition influenced by factors such as genetics, premature birth and exposure to substances during pregnancy.
Despite the challenges that dyslexia poses it does not determine a child's potential. With assistance and support children with dyslexia can excel academically and in areas of their lives. To learn more about this condition and available treatment options check out the blog linked below.

1,867,461 | From Monolith to Microservices: Real-World Case Studies and Lessons Learned | Shifting from a monolithic architecture to microservices can be challenging, but numerous companies... | 0 | 2024-05-28T09:42:23 | https://dev.to/joswellahwasike/from-monolith-to-microservices-real-world-case-studies-and-lessons-learned-5gf | Shifting from a monolithic architecture to microservices can be challenging, but numerous companies have successfully navigated this transformation, gaining significant benefits in scalability, flexibility, and maintainability. In this article, we'll explore real-world examples of companies that have made this transition. We will delve into the obstacles they encountered, the strategies they implemented, and the lessons they learned. To enhance understanding, coding examples will be provided, demonstrating key concepts that can be practically applied.
## Understanding Monolithic and Microservices Architectures
* Monolithic Architecture
This approach involves developing an application as a single, tightly coupled unit. While it simplifies early development and deployment, it can lead to scalability issues and development bottlenecks as the application grows.
* Microservices Architecture
In contrast, this architecture breaks down an application into smaller, loosely coupled services, each responsible for a specific function. This approach allows for independent development, deployment, and scaling, making the system more adaptable and easier to manage.
## Case Study 1: Netflix
* Overview
Netflix serves as a prime example of a successful transition from a monolithic architecture to microservices. The company faced significant scalability and reliability challenges as its user base expanded.
* Challenges
Scalability: The monolithic system struggled to support the growing number of users and simultaneous streams.
Development Bottlenecks: The expanding codebase became increasingly difficult to manage, slowing down development cycles.
Operational Overheads: Deploying new features and fixes was complex and risky.
* Strategies
Incremental Migration: Netflix started migrating non-critical services first, allowing them to refine their strategies with minimal disruption.
Automated Testing and Deployment: Emphasizing automation in testing and CI/CD pipelines ensured reliability and speed.
Service Registry and Discovery: Tools like Eureka were used for service discovery, facilitating communication between microservices.
* Coding Example: Basic Microservice with Spring Boot
* Setting Up the Project
1. Create a new Spring Boot project:
. Use Spring Initializr to generate a new project.
. Select dependencies: Spring Web, Spring Boot DevTools, and Spring Boot Actuator.
2. Open the project in VS Code:
. Unzip the downloaded project and open it in VS Code.
3. Define the service:
. Open src/main/java/com/example/demo/DemoApplication.java and replace its contents with the following code:
```java
package com. example.demo;
import org. spring framework. boot.SpringApplication;
import org. spring framework.boot.autoconfigure.SpringBootApplication;
import org. spring framework.web.bind.annotation.GetMapping;
import org. spring framework.web.bind.annotation.RestController;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@RestController
class HelloController {
@GetMapping("/hello")
public String sayHello() {
return "Hello, Netflix!";
}
}
}
```
4. Run the application:
. In the terminal, run ./mvnw spring-boot: run.
5. Test the service:
. Open a web browser and navigate to http://localhost:8080/hello. You should see "Hello, Netflix!".
### Lessons Learned
. Gradual Transition: Incremental migration reduces risks and allows for iterative improvements.
. Automation is Key: Automated testing and deployment processes are crucial for maintaining reliability.
. Monitoring and Observability: Enhanced monitoring and observability are necessary to manage the complexity of microservices.
## Case Study 2: Amazon
* Overview
Amazon transitioned from a monolithic architecture to microservices to support its growing online marketplace.
* Challenges
. Scalability: The monolithic system couldn't efficiently support the increasing number of customers and services.
. Deployment Risks: Updates had to be rolled out across the entire application, increasing the risk of system-wide failures.
. Limited Flexibility: Adding new features was cumbersome due to tightly coupled components.
Strategies
. Decoupling Services: Amazon decomposed its monolithic application into smaller, independent services.
. Two-Pizza Teams: Adopted the "two-pizza team" concept to keep teams agile and autonomous.
. Event-Driven Architecture: Used an event-driven approach to maintain decoupled services.
* Coding Example: Event-Driven Microservice with Kafka
* Setting Up the Producer Service
1. Create a new Spring Boot project:
. Use Spring Initializr to generate a new project.
. Select dependencies: Spring Web, Spring for Apache Kafka, and Spring Boot DevTools.
2. Open the project in VS Code:
. Unzip the downloaded project and open it in VS Code.
3. Define the producer service:
4. Open src/main/java/com/example/kafka/KafkaProducerApplication.java and replace its contents with the following code:
```java
package com. example.Kafka;
import org. spring framework. boot.SpringApplication;
import org. spring framework.boot.autoconfigure.SpringBootApplication;
import org.springframework.kafka.core.KafkaTemplate;
import org. spring framework.web.bind.annotation.GetMapping;
import org. spring framework.web.bind.annotation.RequestParam;
import org. spring framework.web.bind.annotation.RestController;
@SpringBootApplication
public class KafkaProducerApplication {
public static void main(String[] args) {
SpringApplication.run(KafkaProducerApplication.class, args);
}
@RestController
class ProducerController {
private final KafkaTemplate<String, String> kafkaTemplate;
ProducerController(KafkaTemplate<String, String> kafkaTemplate) {
this.kafkaTemplate = kafkaTemplate;
}
@GetMapping("/send")
public String sendMessage(@RequestParam("message") String message) {
kafkaTemplate.send("testTopic", message);
return "Message sent: " + message;
}
}
}
```
4. Set up Kafka:
. Download and install Apache Kafka from the official website.
. Start Kafka and Zookeeper using the following commands in separate terminals:
sh
# Start Zookeeper
bin/zookeeper-server-start.sh config/zookeeper.properties
# Start Kafka
bin/kafka-server-start.sh config/server.properties
5. Run the producer application:
. In the VS Code terminal, run ./mvnw spring-boot: run.
### Setting Up the Consumer Service
1. Create a new Spring Boot project:
. Use Spring Initializr to generate a new project.

1,867,458 | NestJS Custom Decorator Usage: A Complete Guide | Overview of NestJS and Custom Decorators NestJS is a progressive Node.js framework... | 0 | 2024-05-28T09:37:46 | https://dev.to/jeena_alfredo_b9f53a2a784/nestjs-custom-decorator-usage-a-complete-guide-46ij |
## Overview of NestJS and Custom Decorators
NestJS is a progressive Node.js framework designed for building efficient, reliable, and scalable server-side applications. One of the standout features of NestJS is its robust support for decorators, particularly custom decorators. Decorators in NestJS, built on the foundation of TypeScript, offer a powerful way to enhance the functionality of classes and methods without modifying their original structure.
## Importance of Custom Decorators in NestJS
Custom decorators in NestJS are essential for various reasons. They promote code reusability, enhance readability, and allow developers to encapsulate cross-cutting concerns such as logging, authentication, and validation. By using custom decorators, developers can apply these concerns declaratively, leading to cleaner and more maintainable code.
## Objectives of the Article
This article aims to provide a comprehensive guide on [NestJS custom decorator](https://akvateq.com/blog/nestjs-custom-decorator/) usage. By the end of this guide, you will understand how to create, use, and optimize custom decorators in NestJS, with practical examples and best practices to follow.
## Understanding NestJS
### What is NestJS?
NestJS is a versatile and highly modular framework built with TypeScript. It draws on the principles of Angular, making it an excellent choice for developers familiar with Angular's architecture. NestJS is designed to create scalable and maintainable server-side applications, leveraging a strong typing system and modularity to simplify complex application development.
### Key Features of NestJS
**Modularity:** NestJS allows for the organization of application components into modules, promoting a clear and maintainable structure.
Dependency Injection: Provides a powerful and flexible dependency injection system, enhancing code reuse and testability.
**Decorators:** Extensive use of decorators for defining routes, middleware, and custom logic.
**TypeScript:** Full support for [TypeScript](https://dev.to/typescriptteatime/typescripts-as-keyword-might-not-be-what-you-think-2bpo), offering static typing and modern JavaScript features.
**Versatile:** Compatible with a wide range of libraries and frameworks, including Express and Fastify.
### Advantages of Using NestJS
**Scalability:** Ideal for building large-scale applications due to its modular architecture.
**Maintainability:** Promotes clean and maintainable code through dependency injection and modular design.
**Performance:** Optimized for high performance with support for modern JavaScript engines.
**Community Support:** Active and growing community with extensive documentation and resources.
### NestJS vs. Other Frameworks
NestJS offers several advantages over other frameworks like Express.js and Koa.js, especially for enterprise-grade applications. Its built-in support for TypeScript, modular architecture, and powerful decorator system make it a preferred choice for developers seeking a structured and scalable solution.
## Fundamentals of Decorators
### Definition of Decorators
Decorators are a special kind of declaration in JavaScript and TypeScript that can be attached to a class, method, property, or parameter. They provide a way to add metadata and modify the behavior of these elements in a declarative manner.
### Types of Decorators in JavaScript
Decorators can be classified into several types based on their target:
### Class Decorators
Class decorators are applied to class declarations and can be used to modify or replace the class definition.
### Method Decorators
Method decorators are applied to methods within a class and can alter the method's functionality or add additional behavior.
### Property Decorators
Property decorators are used to annotate properties within a class, often for purposes like validation or dependency injection.
### Parameter Decorators
Parameter decorators are applied to the parameters of class methods and can be used to inject metadata or dependencies into the method.
## How Decorators Work in TypeScript
In TypeScript, decorators are a core feature, and they are implemented as functions that are called with the target of the decorator as an argument. This allows decorators to enhance or modify the target's behavior in a flexible and reusable manner.
## Creating Custom Decorators in NestJS
### Introduction to Custom Decorators
Custom decorators in NestJS are user-defined decorators that extend the framework's functionality. They allow developers to encapsulate and reuse common patterns and behaviors across their applications.
### When to Use Custom Decorators
Custom decorators are particularly useful when you need to apply consistent behavior or logic across multiple classes or methods. Common scenarios include logging, authentication, validation, and error handling.
### Steps to Create a Custom Decorator
Creating a custom decorator in NestJS involves several steps:
Define the Decorator Function: Create a function that will serve as the decorator.
Apply Metadata (Optional): Use Reflect Metadata to store additional information if needed.
Use the Decorator: Apply the decorator to the desired target (class, method, property, or parameter).
Example: Creating a Simple Custom Decorator
**Code Walkthrough**
```
import { SetMetadata } from '@nestjs/common';
export const CustomDecorator = (value: string): MethodDecorator => {
return (target, key, descriptor) => {
SetMetadata('customKey', value)(target, key, descriptor);
};
};
```
### Explanation of the Example
In this example, CustomDecorator is a simple method decorator that uses NestJS's SetMetadata function to attach metadata to the target method. This metadata can later be accessed and used within the application, for instance, in guards or interceptors.
## Use Cases for Custom Decorators
### Logging and Monitoring
Custom decorators can be used to automatically log method calls and their parameters, making it easier to monitor application behavior without scattering logging code throughout the application.
### Authorization and Authentication
Decorators can enforce authorization and authentication policies by checking user roles or permissions before allowing method execution. This approach centralizes access control logic and improves code maintainability.
### Data Validation
Custom decorators can validate method parameters or class properties, ensuring data integrity and reducing boilerplate validation code.
### Caching
By using custom decorators, developers can implement caching mechanisms that store method results based on input parameters, improving application performance.
### Rate Limiting
Decorators can enforce rate-limiting policies to prevent abuse of API endpoints, ensuring that the application remains responsive under load.
## Advanced Custom Decorator Concepts
### Decorator Composition
Decorator composition allows multiple decorators to be combined, enhancing their functionality and reducing redundancy. This can be achieved by applying multiple decorators to a single target or by creating composite decorators.
### Meta-programming with Reflect Metadata
Reflect Metadata is a powerful tool in TypeScript that allows decorators to attach metadata to class elements. This metadata can be retrieved and used at runtime, enabling advanced scenarios like dependency injection and dynamic behavior modification.
### Creating Parameterized Decorators
Parameterized decorators accept arguments that influence their behavior. This allows developers to create highly flexible and reusable decorators that can be tailored to specific requirements.
### Debugging Custom Decorators
Debugging decorators can be challenging due to their declarative nature. Effective debugging techniques include using breakpoints, logging, and tools like Visual Studio Code's debug features to inspect decorator execution and metadata.
## Best Practices for Using Custom Decorators
### Keep Decorators Simple
Complex logic within decorators can lead to hard-to-maintain code. Keep decorator logic simple and focused on a single concern.
### Avoid Business Logic in Decorators
Business logic should reside within services or controllers, not within decorators. Decorators should only handle cross-cutting concerns.
### Use Descriptive Naming
The names of custom decorators should clearly convey their purpose and behavior, making the code more readable and self-documenting.
### Ensure Reusability
Design custom decorators to be reusable across different parts of the application. This promotes consistency and reduces code duplication.
## Case Studies
### Real-world Example 1: Custom Logging Decorator
A custom logging decorator can be used to log method calls and their parameters, aiding in debugging and monitoring.
```
import { Logger } from '@nestjs/common';
export const LogMethod = (): MethodDecorator => {
return (target, key, descriptor) => {
const originalMethod = descriptor.value;
descriptor.value = function (...args: any[]) {
Logger.log(`Method ${String(key)} called with args: ${JSON.stringify(args)}`);
return originalMethod.apply(this, args);
};
return descriptor;
};
};
```
### Real-world Example 2: Custom Role-Based Access Control Decorator
This decorator checks if the user has the required role before executing the method.
```
import { SetMetadata } from '@nestjs/common';
export const Roles = (...roles: string[]): MethodDecorator => {
return (target, key, descriptor) => {
SetMetadata('roles', roles)(target, key, descriptor);
};
};
```
### Real-world Example 3: Custom Validation Decorator
A custom validation decorator ensures that method parameters meet specified criteria.
```
import { BadRequestException } from '@nestjs/common';
export const ValidateParams = (validatorFn: (...args: any[]) => boolean): MethodDecorator => {
return (target, key, descriptor) => {
const originalMethod = descriptor.value;
descriptor.value = function (...args: any[]) {
if (!validatorFn(...args)) {
throw new BadRequestException('Validation failed');
}
return originalMethod.apply(this, args);
};
return descriptor;
};
};
```

1,867,452 | Building Vue3 Component Library from Scratch #6 Gulp Introduce | Preface With the development of front-end tools such as Webpack, Rollup, and Vite, Gulp... | 27,509 | 2024-05-28T09:35:51 | https://dev.to/markliu2013/building-vue3-component-library-from-scratch-6-gulp-introduce-3o4f | gulp | ## Preface
With the development of front-end tools such as Webpack, Rollup, and Vite, Gulp seems to have been replaced. However, that's not the case. It has simply moved from the forefront to the background. We can still see it in many projects, such as ElementPlus and Vant. Nowadays, Gulp is more focused on process control.
> For example, if we want to put an elephant into a refrigerator, we need to follow a simple process: open the refrigerator door -> put the elephant inside -> close the refrigerator door. Using Gulp, we can define these steps and automate this process.
So we can use Gulp to automate common tasks during project development. For example, when packaging a component library, we might need to remove files, copy files, package styles, package components, execute some commands, and package multiple packages with one click. All of these tasks can be controlled by Gulp through custom workflows, making it very convenient.
This article will mainly introduce some common functionalities of Gulp.
## Install Gulp
Firstly, install gulp globally.
```bash
npm install --global gulp-cli
```
Next, we create a new folder called `gulpdemo`, then run `npm init -y` to initialize the project. After that, we install Gulp as a local dependency in this project.
```bash
npm install gulp -D
```
At this point, Gulp is installed. Next, we create `gulpfile.js` file in the root directory. When Gulp runs, it will automatically look for this file.
## Create Task
Each Gulp task is an asynchronous JavaScript function. This function can accept a callback as a parameter or return a Promise or other asynchronous operation object. For example, creating a task can be done like this:
```javascript
exports.default = (cb) => {
console.log("my task");
cb();
};
```
Or
```javascript
exports.default = () => {
console.log("my task");
return Promise.resolve();
};
```
Then, by typing `gulp` in the terminal, this task will be executed.
Series and Parallel
These two concepts are quite easy to understand. Serial execution means tasks are executed one after another, while parallel execution means all tasks are executed simultaneously. Let's first look at a demonstration of serial execution.
```javascript
const { series, parallel } = require("gulp");
const task1 = () => {
console.log("task1");
return new Promise((resolve) => {
setTimeout(() => {
resolve();
}, 5000);
});
};
const task2 = () => {
console.log("task2");
return Promise.resolve();
};
exports.default = series(task1, task2);
```
The console output:
You can see that executing `task1` took 5 seconds, and then `task2` was executed. Now let's look at parallel execution.
```javascript
const { series, parallel } = require("gulp");
const task1 = () => {
console.log("task1");
return new Promise((resolve) => {
setTimeout(() => {
resolve();
}, 5000);
});
};
const task2 = () => {
console.log("task2");
return Promise.resolve();
};
exports.default = parallel(task1, task2);
```
You can see that the two tasks are executed simultaneously.
## src() and dest()
`src()` and `dest()` are two functions that we often use in our actual projects. `src()` represents creating a stream to read from the file system, while `dest()` creates a stream to write to the file system. Let's write a simple example for copying files.
## Copy
Before writing the task, let's create a `src` directory in the root of our project to store the files to be copied. Inside the `src` directory, create a few files.
Next, we write our copy task in `gulpfile.js` to copy all files from the `src` directory to the `dist` directory.
```javascript
const { src, dest } = require("gulp");
const copy = () => {
return src("src/*").pipe(dest("dist/"));
};
exports.default = copy;
```
Then, run `gulp` (which by default executes `exports.default`), and you'll notice that a `dist` folder has been created in the root directory.
## Process Less
Next, let's write a task to process LESS files. First, we need to install `gulp-less`.
```bash
npm i -D gulp-less
```
Next, create a `style` directory inside the `src` folder, and then create an `index.less` file inside the `style` directory. Write a piece of LESS syntax style in it. For example:
```css
@color: #fff;
.wrap {
color: @color;
}
```
Next, let's write our `lessTask` in `gulpfile.js` to parse the LESS files in the `style` directory into CSS and write them into `dist/style`.
```javascript
const { src, dest } = require("gulp");
const less = require("gulp-less");
const lessTask = () => {
return src("src/style/*.less").pipe(less()).pipe(dest("dist/style"));
};
exports.default = lessTask;
```
Then, run the `gulp` command, and you'll find `dist/style/index.css`.
```css
.wrap {
color: #fff;
}
```
We can add prefixes to our CSS.
```bash
npm install gulp-autoprefixer -D
```
Update `src/style/index.less` to:
```css
@color: #fff;
.wrap {
color: @color;
display: flex;
}
```
Then, use `gulp-autoprefixer` in `gulpfile.js`.
```javascript
const { src, dest } = require("gulp");
const less = require("gulp-less");
const autoprefixer = require("gulp-autoprefixer");
const lessTask = () => {
return src("src/style/*.less")
.pipe(less())
.pipe(
autoprefixer({
overrideBrowserslist: ["> 1%", "last 2 versions"],
cascade: false,
})
)
.pipe(dest("dist/style"));
};
exports.default = lessTask;
```
The processed `dist/style/index.css` will look like this:
```css
.wrap {
color: #fff;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
}
```
## Watch File Changes with browser-sync
Browser-sync is a very useful browser synchronization testing tool. It can set up a static server, monitor file changes, and refresh the page (HMR). Let's take a look at how to use it.
Firstly, you definitely need to install it.
```bash
npm i browser-sync -D
```
Then, we create index.html in the root directory.
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
hello world
</body>
</html>
```
Then, configure it in the gulpfile.js.
```javascript
const browserSync = require("browser-sync");
const browserTask = () => {
browserSync.init({
server: {
baseDir: "./",
},
});
};
exports.default = browserTask;
```
At this point, a server will be launched on the default port 3000. Next, let's see how to monitor changes.
Firstly, we need to monitor changes in the file, which can be done using browserSync's watch. After detecting changes in the file, the page is then refreshed.
```javascript
const { watch } = require("browser-sync");
const browserSync = require("browser-sync");
const { series } = require("gulp");
const reloadTask = () => {
browserSync.reload();
};
const browserTask = () => {
browserSync.init({
server: {
baseDir: "./",
},
});
watch("./*", series(reloadTask));
};
exports.default = browserTask;
```
At this point, if you modify a file under 'src', the browser will refresh.
Now we will import the style from 'dist/style/index.css' into 'index.html', and then simulate a simple build flow.
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<link rel="stylesheet" href="../dist/style/index.css" />
</head>
<body>
<div class="wrap">hello world</div>
</body>
</html>
```
At this point, our process is: compile the less files -> write css into 'dist/style' -> trigger page update.
We can write our 'gulpfile.js' like this:
```javascript
const { src, dest } = require("gulp");
const { watch } = require("browser-sync");
const browserSync = require("browser-sync");
const { series } = require("gulp");
const less = require("gulp-less");
const autoprefixer = require("gulp-autoprefixer");
const lessTask = () => {
return src("src/style/*.less")
.pipe(less())
.pipe(
autoprefixer({
overrideBrowserslist: ["> 1%", "last 2 versions"],
cascade: false, // format
})
)
.pipe(dest("dist/style"));
};
//refresh
const reloadTask = () => {
browserSync.reload();
};
const browserTask = () => {
browserSync.init({
server: {
baseDir: "./",
},
});
watch("./*.html", series(reloadTask));
//watch to run task
watch("src/style/*", series(lessTask, reloadTask));
};
exports.default = browserTask;
```
At this point, whether we change the style or the HTML, it can trigger a page update.
## Finally
In the future, I will use gulp to handle the style packaging part of the Vue3 component library that I am currently developing. If you are interested in component library development, you can follow this series. I will implement some commonly used components and present them in the form of blog.

1,867,448 | How AWS Shield Protects You From DDoS? | The threat of cyber attacks is large in today's interconnected digital world, where businesses and... | 0 | 2024-05-28T09:33:05 | https://dev.to/jay_tillu/how-aws-shield-protects-you-from-ddos-5efp | cloud, cloudcomputing, security, aws | The threat of cyber attacks is large in today's interconnected digital world, where businesses and individuals rely heavily on online services. One such threat that has gained fame in recent years is the Distributed Denial of Service (DDoS) attack. In this blog post, we'll delve into what DDoS attacks are, how they work, their impact, and measures to mitigate them.
## Understanding DDoS Attacks
At its core, a DDoS attack aims to disrupt the normal operation of a targeted server, service, or network by flooding it with an overwhelming volume of traffic. The "distributed" aspect refers to the utilization of multiple compromised devices, forming a botnet, to generate this traffic. These devices can range from computers and smartphones to Internet of Things (IoT) devices, all under the control of the attacker.
## How DDoS Attacks Work
DDoS attacks typically unfold in several stages:
1. **Botnet Formation:** Attackers infect numerous devices with malware, gaining control over them and forming a botnet.
2. **Command and Control:** The attacker issues commands to the botnet, instructing it to send a flood of requests to the target server or network.
3. **Traffic Flood:** The botnet obediently follows these instructions, inundating the target with a deluge of traffic, thereby overwhelming its resources.
DDoS attacks are particularly troublesome because they're difficult to stop. Unlike a lone attacker, a botnet spreads the attack across numerous devices, making it hard to identify and block the source.
## Impact of DDoS Attacks
The consequences of a successful DDoS attack can be severe:
- **Service Disruption:** The targeted service becomes inaccessible to legitimate users, resulting in downtime and loss of productivity.
- **Financial Losses:** Businesses may suffer financial losses due to interrupted operations, decreased customer trust, and potential regulatory penalties.
- **Reputation Damage:** Organizations targeted by DDoS attacks often experience reputational damage, eroding customer confidence and brand loyalty.
## Common Reasons behind DDoS Attack
But why do attackers unleash such chaos? Here are some common reasons:
- **Extortion Money:** Sometimes, attackers use DDoS attacks for financial gain. They threaten to take down a website unless the victim pays a ransom.
- **Disrupting the System:** Hacktivists might use DDoS attacks to disrupt the operations of a company or organization they disagree with.
- **Taking Down the Competition:** Malicious businesses might use DDoS attacks to sabotage their competitor's online presence.
Thankfully, there are ways to defend against DDoS attacks. Security measures like DDoS mitigation services can help filter out suspicious traffic and keep websites and online services up and running.
## How AWS Shield Protects You From DDoS

The term "OTT" describes a streaming service that uses an advanced internet connection... | 0 | 2024-05-28T09:31:26 | https://dev.to/mega_p_8cb8553eb8aab42923/what-is-ott-and-how-does-it-function-1ied | ott, ottplatform, ottplatformprovider | **What is OTT?**
The term "[OTT](https://www.webnexs.com/ott-platform.php)" describes a streaming service that uses an advanced internet connection to deliver audio and video content. As opposed to distributing content through more conventional channels like television networks, cable operators, and Internet Protocol television operators. The term "over-the-top content" mostly describes movies or television shows that viewers watch on their linked TVs, computers, or phones.
OTT is an alternative channel that allows businesses to provide end consumers with video, audio, and messaging content. Marketers may deliver content more cheaply and effectively than mainstream media outlets by using such a platform. Additionally, users or clients can watch live streaming programs or playback content on demand with the support of this platform.
With over-the-top (OTT) delivery, media content can be made available online without the involvement of a third party operator. While OTT is primarily recognized for its use in TV and video content, the word also is applicable to multimedia, text message, and contact.
Put simply, over-the-top (OTT) television makes use of a technique for delivering media through the wider internet that allows anybody with a device that can connect to the internet to view media. In order to access a content stream, consumers only need to cover the cost of internet service and, if necessary, an OTT subscription.
**How does it function?**
Content is pre-recorded and stored in the content delivery network (CDN) to facilitate its operation. The video files are already stored on a server, and the over-the-top ([OTT](https://www.webnexs.com/ott-platform.php)) provider broadcasts them via streaming video technology, distributing the content over the internet. Users of the over-the-top app ask for a particular movie to play when they use it.
The video is obtained by the OTT from the local CDN by sending a request, and it is then sent to the customer in media segments. Additionally, the platform uses the appropriate digital rights management (DRM) server to generate a request.
The media is presented to the viewer as intended by the server after it has been decrypted. Content is only delivered by an over-the-top provider upon request from a client. They use an individual or single-cast transmission technique for this. This implies that each end-user device connects to the content provider in a different way.
Customers can stream one movie to just one gadget with the use of over-the-top (OTT) services. The infrastructure is provided only by the internet service providers (ISPs) via which a consumer streams content. The copyright management of content, video delivery, and content watching are not their responsibilities.
**Advantages of OTT platform
If everyone receives the exclusive material after subscribing to a subscription, then adopting an [OTT platform](https://www.webnexs.com/ott-platform.php) has a lot of advantages. During the pandemic, OTT platforms grew even more, making a major contribution to the growth and advancement of the knowledge age.
**Clean audio and visuals**
All over-the-top platforms aim to keep their materials as high-quality as possible. It will be simpler to hear and see how good the movies are at a higher speed. You have the option to personalize the audio and video quality to your preference.
**Accessibility made simple**
Another great advantage of [OTT platforms](https://www.webnexs.com/ott-platform.php) is instant viewing, which lets you watch any movie or show at any time, no matter when it was launched. Without having to stand in a lengthy line for tickets or deal with intrusive commercials when watching a movie on TV, you may binge-watch your favorite online show as often as you'd like. Certain platforms offer complete access to their programs in exchange for a set monthly cost.
**Economy of scale**
A monthly subscription gives you access to a wide range of programs. One of the biggest advantages of streaming platforms is the ability to watch favorite movies, shows, live sports telecasts, and international web series while on the road. When it comes to watching digital entertainment online, cable providers don't have to deal with outages or monthly costs. It's affordable because anyone who wants to watch digital video can sign up and pay a subscription fee for either a month or a annual subscription fee.
**Real content**
You can access a wide range of exclusive, unique material that is only accessible through a license for a minimal monthly charge. You, as the account holder, are in charge of managing this content alone, free from outside intervention.
**Cross-platform assistance**
You may view your favorite material any time and any place you want thanks to OTT platforms. With an internet connection, you can effortlessly access these files on your laptop, smartphone, smart TV, and other audio-visual devices. Video-on-demand (SVoD) services are synonymous with this service, and foreign digital content is readily available.
**Disadvantages of the OTT Platform**
Without a doubt, OTT platforms have several advantages. The primary reasons for this are the price issue and a wealth of diverse content. There are a few drawbacks to the [OTT platform ](https://www.webnexs.com/ott-platform.php)as well. A few of these include:
**Buffering problems**
To watch videos properly while streaming media, a stable connection is necessary. An inadequate connection to the internet will make HD streaming difficult if you struggle to keep up with it. You won't experience any buffering when watching videos at 2 MBps or greater.
**Absence of censorship**
OTT platforms are unrestricted by governments and operate independently. They offer a broad variety of content with no age limitations, and their only goal is to draw in more viewers. Nevertheless, the content available on these platforms is subject to certain limits.
**Online restriction**
You can access streaming services, provided you have access to the internet. One disadvantage is that you can only access the media by streaming it from a website. Only people without an internet presence can view the content using this method. You also need to have an account on the streaming site in order to watch your favorite show.
**Addicting at times**
Because there are so many new web series, films, and television shows published each week, users are more inclined to squander their free time on OTT platforms. As one online series concludes, another is suggested. Individuals who view live video streaming more frequently are more likely to develop an addiction to internet material.

1,867,445 | find命令，由不能打印‘afile’总结到的 | 关于 find命令是常用到的，读到manpage里面一段话不是很明白，于是整个manpage读了一遍终于整明白了。 Please note that -a when... | 0 | 2024-05-28T09:30:54 | https://dev.to/shouhua_57/findming-ling-you-bu-neng-da-yin-afilezong-jie-dao-de-2cep | find, xargs, afile | ## 关于
find命令是常用到的，读到manpage里面一段话不是很明白，于是整个manpage读了一遍终于整明白了。
```
Please note that -a when specified implicitly (for example by two
tests appearing without an explicit operator between them) or
explicitly has higher precedence than -o. This means that `find .
-name afile -o -name bfile -print` will never print afile.
```
就是说`find . -name afile -o -name bfile -print`命令即使afile存在也不会打印出来，这就很奇怪了，读起来是afile或者bfile就print，看起来很直观，但是不是这么判断的，下面我们总结下manpage和常见用法习惯。
## 用法
```bash
find [OPTIONS] [starting-point] [EXPRESSION]
```
- OPTIONS 里面 `-H -L -P` 用于表示如何处理symbolic link; `-O` 表示优化级别，一般用不到; `-D` 用于调试，比如
```bash
`-D help` 打印出所有调试选项
`-D tree` 打印出predicate list，可以看到默认添加的参数等，非常有用
```
- starting-point 可以有多个，最好使用相对路径和绝对路径，比如`./abc`和`/abc`, 避免被乱解释了，比如路径开头为`-`，就会被解释为expression argument。
- `EXPREESION` 用于表示怎么匹配文件和匹配后怎么做。包括以下几个部分： `Tests`, `Actions`, `Global options`, `Positional options`, `Operators`。
1. `Tests`
返回`true`或者`false`。根据文件属性包括日期、权限、状态、大小等，选择我们关心部分作为测试参数，比如`-empty`表示文件内容为空的判断
2. `Actions`
返回`true`或者`false`。 匹配文件怎么做，比如，`-print`将当前匹配文件名打印
3. `Global Options`
总是返回`true`。 影响所有的tests和actions参数，比如, `-depth`指示find按照深度优先方式traverse
4. `Positional Options`
总是返回`true`。 只是影响他之后的tests和actions参数，比如，`-regextype` 指示他后面使用的regex方言类型
5. `Operators`
逻辑连接参数，如果expr之间没有逻辑连接默认是`-a`表示and。 **而且不管显式或者隐式`-a`优先级都高于`-o`**，其他有趣的还包括
`()` 调整precedence
`! expr`或者`(-not expr)` 取反
`expr1, expr2` 2个表达式都会执行，但是结果取expr2的, 举例
```bash
find . ! -path './node_modules/*' \( \( -type f -print \) , \( -type d -exec echo 'directory: {}' \; \) \)
```
## 注意点
1. 默认action是`-print`, 这里的默认是说，如果命令中没有任何一个action, 会在最后添加`-a -print`, 但是如果有多个判断分支，但一个有action, 那不会添加默认，比如
```bash
find . -name afile -o -name bfile -print
```
这个afile判断是不会添加`-print`的，由于`-a`优先级高于`-o`, 所以最后变成了
```bash
find . ( -name afile ) -o ( -name bfile -a -print )
```
其中默认添加了`-a`, 遇到afile时候就会跳过了，相当于continue, 可以使用`-D tree`看到最后执行的命令表达式
`find -D tree . -name afile -o -name bfile -print`会得到：
```bash
Optimized Command Line:
-name afile [est success rate 0.1] -o [est success rate 0.2] ( -name bfile [est success rate 0.1] -a [est success rate 0.1] -print [est success rate 1] )
```
2. 如果只有`-prune`或者`-quit`，还是会添加默认`-print`。
`-prune`表示如果是文件夹，不递归他。`-prune`总是返回true, 常用于跳过某个文件或者目录，比如`find . -path './node_modules' -prune -o -type f -print`;
`-quit`用于成功了整个命令退出，比如打印第一个匹配成功的文件 `find . -path './node_moduels' -prune -o -type f -print -quit`。
3. 以下actions会禁止`-print`, 包括`-delete, -exec, -execdir, -ok, -okdir, -fls, -fprint, -fprintf, -ls, -print, -printf`。
4. `-maxdepth 0` (global options)可以指示只处理start point
5. 为了防止被当成SHELL中特殊字符，find命令中参数有些要注意转译，比如括号、分号、加号等，凡是在SHELL中特殊字符尽量转移，不然后果未知, 比如`find . -path './node_modules' -prune -o -type f -exec echo {} ;`如果最后的`;`不转译，find命令找不到结束符号报错。还有最后的`+`也是一样, `find . -path './node_modules' -prune -o -type f -ok echo {} \;`, `-ok`每次执行命令都会询问。
6. `-exec COMMAND [\;|\+]`
最后`;`和`+`, 前者是每次都执行一次COMMAND, 后者是将参数以空格形式分割，最后执行一次COMMAND。
7. `-name pattern`
表示file的**basename**是否符合pattern, 比较时候会去掉leading directory
8. `-path pattern`
匹配的是整个filename, 包括路径, 比如
```bash
find . \( ! -path './node_modules/*' ! -name 'eslint.config.js' -type f \) -print
```
9. `-print0`
主要是防止文件名含有特殊字符，比如`\n`, `space`等，批处理时会被转译截断，所以使用`\0`结尾，跟`xargs -0`配对使用
## 答案
`-a`优先级比`-o`高，另外`-name afile`不会添加`-print`, 所以即使匹配到了还是会无声的过了，最后只是打印了bfile, 如果存在的话。 | shouhua_57 |

By integrating ChatOpenAI, a component tailored to work with OpenAI’s conversational models, developers can streamline the deployment and management of conversational AI systems. This guide will walk you through the steps to integrate ChatOpenAI within LangChain, from setting up your environment to running a chat session.
**Setting Up Your Environment**
Before integrating ChatOpenAI, it is essential to prepare your development environment. Ensure you have Python installed on your system, with version 3.7 or newer recommended for compatibility with LangChain and ChatOpenAI. Additionally, setting up a virtual environment is advisable to manage dependencies and avoid conflicts with other Python projects.
**Installing LangChain**
Once your environment is prepared, the next step is to install LangChain. You can easily install LangChain using pip, Python’s package installer. Make sure your virtual environment is activated before running the following command:
`pip install langchain`
This command downloads and installs LangChain along with its dependencies.
**Importing ChatOpenAI**
After installing LangChain, the next step is to import ChatOpenAI into your project. ChatOpenAI is a class within LangChain that simplifies interaction with OpenAI’s conversational models. Importing it is straightforward:
`from langchain.chat_openai import ChatOpenAI`
This line of code makes the ChatOpenAI class available in your script, enabling you to use its functionalities.
**Configuring ChatOpenAI**
To use ChatOpenAI, you need to initialize it with your OpenAI API key. This key allows your application to communicate with OpenAI’s API and utilize its language models. Here’s how you can initialize ChatOpenAI:
`# Initialize ChatOpenAI with your OpenAI API key
chat_openai = ChatOpenAI(api_key="your_openai_api_key_here")`
Replace “your_openai_api_key_here” with your actual OpenAI API key. This step is crucial for authenticating your requests to OpenAI’s services and ensuring proper access to their resources.
**Creating a Conversation**
With ChatOpenAI configured, you are now prepared to develop a function that manages the conversation logic. This function will receive user input, transmit it to the model, and showcase the model’s response. Here’s a basic example:
`def start_conversation():
while True:
user_input = input("You: ")
if user_input.lower() == "quit":
break
response = chat_openai.generate_response(user_input)
print("AI:", response)`
This function establishes an interactive loop where users can input messages, and the AI responds accordingly. Entering “quit” terminates the conversation.
**Running the Chat
**To test your setup and see ChatOpenAI in action, simply call the start_conversation function:
`# Start the conversation
start_conversation()`
Executing this script in your terminal or command prompt will start a chat session where you can engage with the AI model.
## Example: Building a Feedback Collection Bot with Novita AI LLM API
In this example, we’ll explore the creation of a feedback collection bot with Novita AI LLM API, a close source LLM API aiming to offer developers reliable, cost-effective and privacy-ensured inference engine, which OpenLLM cannot guarantee.
This bot interacts with users to gather their feedback on a service and responds accordingly, considering the sentiment of the feedback. While this example employs a simple form of sentiment analysis, it demonstrates the fundamental procedures for constructing more advanced conversational agents capable of conducting sophisticated sentiment analysis.
For users who want to run a RAG system with no coding experience, you can try out Novita AI [LLM API](https://novita.ai/llm-api), where you can create awesome AI Apps with a No Code Builder!
The feedback collection bot acts as a straightforward yet powerful tool for businesses to interact with customers and acquire valuable insights into their services.

This prompt interaction has the potential to improve customer satisfaction and offer real-time data for service enhancement.
## Step-by-Step Implementation
**Setting Up the Bot**
Before proceeding, make sure LangChain and ChatOpenAI are correctly installed and configured as detailed in the preceding sections. Once done, you can start coding the bot:
`from langchain.chat_openai import ChatOpenAI
# Initialize ChatOpenAI with your OpenAI API key
chat_openai = ChatOpenAI(api_key="your_openai_api_key_here")`
**Creating the Interaction Logic**
At the heart of the feedback bot lies its capability to engage with users and analyze their input. Here’s how you can implement the interaction logic:
`def feedback_bot():
print("Hello! How was your experience with our service today?")
while True:
feedback = input("Your feedback: ")
if feedback.lower() == "quit":
break
analyze_feedback(feedback)`
This function initiates a conversation and continuously collects user feedback until the user types “quit”.
**Analyzing Feedback**
To keep things simple, this example employs a basic keyword search to ascertain sentiment. Nevertheless, you can enhance this by integrating more sophisticated natural language processing techniques accessible through LangChain and OpenAI.
`def analyze_feedback(feedback):
# Simple keyword-based sentiment analysis
positive_keywords = ["great", "excellent", "good", "fantastic", "happy"]
negative_keywords = ["bad", "poor", "terrible", "unhappy", "worst"]
if any(word in feedback.lower() for word in positive_keywords):
print("AI: We're thrilled to hear that! Thank you for your feedback.")
elif any(word in feedback.lower() for word in negative_keywords):
print("AI: We're sorry to hear that. We'll work on improving.")
else:
print("AI: Thank you for your feedback. We're always looking to improve.")`
This function examines the existence of specific keywords to assess the sentiment of the feedback. When positive or negative keywords are detected, corresponding responses are triggered.
**Enhancing the Bot with Advanced Sentiment Analysis**
To enhance the feedback bot’s robustness and depth, you can integrate advanced sentiment analysis models. LangChain facilitates seamless integration of various language models capable of delving deeper into text analysis, grasping nuances and context more effectively than basic keyword searches. For example, leveraging OpenAI’s GPT models can lead to more precise sentiment interpretation and even the generation of personalized responses based on the feedback context.
