```cpp
#include <iostream>
using namespace std;
void foo() {
cout << "foo()" << endl;
}
int main(void)
{

}
```
卻得到以下的輸出：
```

研究了一下才發現, 雖然 `cout` 所屬的類別 [`std::basic_ostream`](https://en.cppreference.com/w/cpp/io/basic_ostream/operator_ltlt#Version_18) 有以下的 `<<` 運算子多載版本：
```cpp
basic_ostream& operator<<( const void* value );
basic_ostream& operator<<( const volatile void* value );
```
不過指向特定型別的指位器並不能自動轉型成 `(void*)`, 但是卻可以[自動轉型到 `bool`](https://en.cppreference.com/w/cpp/language/implicit_conversion#Boolean_conversions), 因此編譯器會[選用以下這個版本](view-source:https://en.cppreference.com/w/cpp/io/basic_ostream/operator_ltlt%23Version_18)：
```cpp
basic_ostream& operator<<( bool value );
```
它會用 1 和 0 表示 `true` 和 `false`, 所以不是指向 `null` 的指位器就被轉成 `true`, 印出 1 了。
如果要印出位址, 就必須先手動把指位器轉型成 `(void*)`, 像是這樣：
```cpp
#include <iostream>
using namespace std;
void foo() {
cout << "foo()" << endl;
}
int main(void)
{
cout << (void*)foo << endl;
}
```
才會印出位址：
```

1,898,638 | 5 Businesses to Start as a Software Developer | Software development is a career with many ways to expand, which includes business. These are my... | 0 | 2024-06-24T09:19:16 | https://dev.to/martinbaun/5-businesses-to-start-as-a-software-developer-2j83 | programming, productivity, learning, softwaredevelopment |
Software development is a career with many ways to expand, which includes business.
These are my top five businesses to run as a software developer, so let’s discuss them.
## 1. Freelancing
Freelancing is an excellent business to begin. You are the boss and take on clients according to your availability. Freelancing frees you to choose your clients, work hours, and the projects you are interested in.
These jobs build your reputation and client base, which brings in more clients. Create a freelancing profile and build your portfolio of completed tasks and projects. You can create a freelancer profile on UpWork, Fiverr, or Freelancer.
Freelancing offers the best growth potential that can branch out to different software development disciplines, such as consultancy. Building a phenomenal portfolio earns you respect and command of the market, allowing you to branch into consultancy. You can then run your consultancy as you continue freelancing.
Freelancing also frees you to be contacted by various firms or organizations, allowing you to work on multiple projects simultaneously. The room to diversify is endless and limited by how much you can handle.
Freelancing has its pros and cons. The pros are no upfront costs to start the business, and you can start immediately. You'll trade time and experience for monetary compensation. This makes it a worthwhile venture.
The cons associated with freelancing is the difficulty of scaling it up. Gaining new clients may force you to expand your venture. You’ll need to hire people to work for you. You’ll have to learn how to handle an establishment, the legalities of an enterprise, and how to run it. Luckily, I have written everything you need to know about this.
Read: *[Worst Hire - my lessons](https://martinbaun.com/blog/posts/worst-hire-my-lessons/)*
## 2. Independent Projects
You can take part in independent projects that interest you. These projects can be as simple as a consultation to being the full-stack developer on a project. A good reputation in software development will make you an attractive asset for many independent projects.
You can team up with previous colleagues or clients and become part of their independent projects. This collaborative approach is an alternative to freelancing. You still maintain the freedom to choose which independent projects to participate in, which people to work with, and which discipline to pursue.
You gain valuable experience and widen your network, which puts you in a prime position to land more lucrative roles in other projects.
Independent projects have their pros and cons. The pros are that you’ll be well-embedded in the project. You’ll be an integral part of the team, and your name will gain recognition within the independent project ecosystem.
The cons of independent projects are similar to those of freelancing. You’ll have to scale up and take on other developers to form an organization. Scaling up is difficult. You’ll need to learn everything about creating an organization, the legalities, and how to run it.

## 3. App Development and SaaS
Software as a service (SaaS) and App development are good business opportunities to pursue. SaaS is a popular method of delivering software to clients over the Internet. You can create any software and make it available as a service over the Internet.
This software ranges from project management tools like [Goleko](https://goleko.com/) to excellent document creation software like [ElegantDoc ](https://elegantdoc.com/)that I created.
Clients subscribe to use this software, which earns you income. You are free to improve your software, improving the user experience(UX).
App development is another lucrative business idea. Mobile devices, tabs, and computers use applications. You can create any application or work on applications by independent developers. You can work as a full-stack developer or a dedicated tester in the app development process.
Working on applications and SaaS gives you a great avenue to monetize your skill set.
App development and SaaS have pros and cons. The pros are that you’ll make money even in your sleep. The apps and SaaS will continue generating income through subscriptions, in-app purchases, or both. This makes it a lucrative option to pursue.
The cons of app development and SaaS are the need for investment. You must invest your time and resources into these projects. These investments do not pan out, most times. This is a risk associated with app development and SaaS. The risks are just as significant as the potential rewards.
## 4. Plugins
You can create a business centered around creating plugins for software development companies. Plugins are a niche and unsaturated market in software development.
Plugins work as a simple way of improving software or adding functionality to it to improve the software and enhance user experience (UX).
Create a portfolio consisting of successful plugin projects done for various software. You can create plugins that work well with generic software and monetize them to generate income. This service will improve the software's reputation and increase the money generated.
Plugins have pros and cons. The pros of plugins are that they require less marketing. The marketing is handled by the platform that houses your plugin. You earn money even in your sleep when your plugins are used on these platforms. This makes plugins lucrative to pursue.
The cons of plugins are that your income depends on the platform that houses your plugin. You stand to lose everything if you get banned from the website or the platform changes its terms of service. Any of these changes may result in you losing millions overnight and going down to zero.
## 5. Cybersecurity
You can branch into cybersecurity as your business of choice. You can specialize in this field and work on improving the security of the software.
Cybersecurity is a crucial aspect of many organizations, and preventing attacks that can lead to data loss or catastrophic consequences is pivotal. You can work in cybersecurity as a consultant or actively involve yourself in the coding process to enhance the security of the software.
Cybersecurity is a high-demand venture, which makes it a lucrative business plan.
Cybersecurity has pros and cons. The pros of cybersecurity depend on the branch of software development you’ve chosen. It is easier to transition into cybersecurity as a programmer, as the two disciplines are similar.
The con of cybersecurity involves having a lot to learn. This is the case for anyone who is not a programmer. The learning process is heavy and requires time and commitment to accomplish.

1,898,633 | Essential JavaScript topics to master before diving into React | Welcome, budding React developers! Before you dive headfirst into the ocean of React, it's crucial to... | 27,828 | 2024-06-24T09:14:13 | https://imabhinav.dev/blog/essential-javascript-topics-to-master-before-diving-into-react-9-13-42 | webdev, javascript, react, beginners | Welcome, budding React developers! Before you dive headfirst into the ocean of React, it's crucial to ensure your JavaScript life raft is well-equipped. While React makes building user interfaces a breeze, it assumes you have a solid grounding in JavaScript. Here’s a comprehensive guide to the essential JavaScript topics you need to master before embarking on your React journey.
### 1. Variables and Data Types
JavaScript variables are like the drawers in your coding kitchen where you store your ingredients (data). Understanding how to properly declare and use them is fundamental.
#### Example:
```javascript
// Using let and const
let myName = "Abhinav";
const myAge = 21;
// Data types
let isStudent = true; // Boolean
let skills = ["JavaScript", "React", "Django"]; // Array
let address = { city: "Bhopal", state: "MP" }; // Object
```
### 2. Functions
Functions are the bread and butter of JavaScript. Understanding the different ways to declare functions and their scope is vital.
#### Example:
```javascript
// Function Declaration
function greet(name) {
return `Hello, ${name}!`;
}
// Function Expression
const greet = function(name) {
return `Hello, ${name}!`;
}
// Arrow Function
const greet = (name) => `Hello, ${name}!`;
// Immediately Invoked Function Expression (IIFE)
(function() {
console.log("IIFE runs immediately!");
})();
```
### 3. Scope and Closures
Scope determines the accessibility of variables, while closures allow functions to access variables from an enclosing scope even after that scope has finished execution.
#### Example:
```javascript
function outerFunction() {
let outerVar = "I am outside!";
function innerFunction() {
console.log(outerVar); // "I am outside!"
}
return innerFunction;
}
const inner = outerFunction();
inner();
```
### 4. Asynchronous JavaScript
JavaScript’s single-threaded nature requires a good understanding of asynchronous operations to handle tasks like data fetching. This includes callbacks, promises, and async/await.
#### Example:
```javascript
// Callback
setTimeout(() => {
console.log("Callback after 2 seconds");
}, 2000);
// Promise
const fetchData = new Promise((resolve, reject) => {
setTimeout(() => {
resolve("Data fetched!");
}, 2000);
});
fetchData.then((data) => {
console.log(data); // "Data fetched!"
});
// Async/Await
const fetchDataAsync = async () => {
const data = await fetchData;
console.log(data); // "Data fetched!"
};
fetchDataAsync();
```
### 5. The DOM (Document Object Model)
Manipulating the DOM is key to making web pages interactive. Understanding how to select and manipulate DOM elements is crucial.
#### Example:
```javascript
// Selecting elements
const button = document.querySelector('button');
const div = document.getElementById('myDiv');
// Manipulating elements
button.addEventListener('click', () => {
div.textContent = "Button Clicked!";
div.style.color = 'red';
});
```
### 6. Event Handling
Events are actions that occur in the browser, like clicks or keypresses. Handling these events properly is fundamental for interactive web applications.
#### Example:
```javascript
document.getElementById('myButton').addEventListener('click', function() {
alert('Button was clicked!');
});
document.addEventListener('keydown', function(event) {
if (event.key === 'Enter') {
console.log('Enter key was pressed.');
}
});
```
### 7. Object-Oriented Programming (OOP)
While JavaScript is a prototype-based language, it supports object-oriented programming principles like classes and inheritance.
#### Example:
```javascript
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
greet() {
console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`);
}
}
const abhinav = new Person('Abhinav', 21);
abhinav.greet();
```
### 8. The `this` Keyword
The context of `this` can be tricky but is essential for mastering JavaScript, especially when working with objects and classes.
#### Example:
```javascript
const person = {
name: 'Abhinav',
greet() {
console.log(`Hello, my name is ${this.name}.`);
}
};
person.greet(); // "Hello, my name is Abhinav."
// Arrow function and this
const personArrow = {
name: 'Abhinav',
greet: () => {
console.log(`Hello, my name is ${this.name}.`); // `this` is not bound in arrow functions
}
};
personArrow.greet(); // "Hello, my name is undefined."
```
### 9. Arrays and Array Methods
Arrays are a core data structure in JavaScript. Knowing how to manipulate them with methods like `map`, `filter`, and `reduce` is crucial.
#### Example:
```javascript
const numbers = [1, 2, 3, 4, 5];
// Map
const doubled = numbers.map(num => num * 2);
console.log(doubled); // [2, 4, 6, 8, 10]
// Filter
const even = numbers.filter(num => num % 2 === 0);
console.log(even); // [2, 4]
// Reduce
const sum = numbers.reduce((total, num) => total + num, 0);
console.log(sum); // 15
```
### 10. Destructuring
Destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.
#### Example:
```javascript
// Array Destructuring
const [a, b, c] = [1, 2, 3];
console.log(a, b, c); // 1 2 3
// Object Destructuring
const person = {
name: 'Abhinav',
age: 21
};
const { name, age } = person;
console.log(name, age); // "Abhinav" 21
```
### 11. Spread and Rest Operators
The spread and rest operators (`...`) are powerful tools for working with arrays and objects.
#### Example:
```javascript
// Spread Operator
const arr1 = [1, 2, 3];
const arr2 = [...arr1, 4, 5, 6];
console.log(arr2); // [1, 2, 3, 4, 5, 6]
// Rest Operator
function sum(...args) {
return args.reduce((total, num) => total + num, 0);
}
console.log(sum(1, 2, 3)); // 6
```
### 12. Template Literals
Template literals make string interpolation and multi-line strings a breeze.
#### Example:
```javascript
const name = 'Abhinav';
const greeting = `Hello, my name is ${name}.`;
console.log(greeting); // "Hello, my name is Abhinav."
```
### 13. Modules
Modules are a way to organize and reuse code. Understanding `import` and `export` is key to managing larger codebases.
#### Example:
```javascript
// module.js
export const name = 'Abhinav';
export function greet() {
console.log(`Hello, ${name}!`);
}
// main.js
import { name, greet } from './module.js';
console.log(name); // "Abhinav"
greet(); // "Hello, Abhinav!"
```
### 14. Error Handling
Proper error handling is essential for building robust applications.
#### Example:
```javascript
try {
throw new Error('Something went wrong!');
} catch (error) {
console.error(error.message); // "Something went wrong!"
} finally {
console.log('This will run regardless.');
}
```
### 15. Fetch API
The Fetch API provides a modern, promise-based way to make asynchronous requests.
#### Example:
```javascript
fetch('https://api.example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
```
### Conclusion
Mastering these essential JavaScript topics will not only make your transition to React smoother but also empower you to tackle more complex projects with confidence. So, roll up your sleeves, get your hands dirty with JavaScript, and then dive into the exciting world of React!

Server Actions are defined as asynchronous functions marked with the 'use server' directive, and can be called directly from client-side components.
Here's an example of defining a Server Action to add a new todo item to a database:
```
// app/actions.js
'use server'
import { addTodo } from '@/lib/db'
export async function addTodoAction(formData) {
const text = formData.get("text")
await addTodo({ text, completed: false })
}
```
In a client-side component, you can then call this Server Action using the action prop on a form element:
```
// app/page.js
import { addTodoAction } from './actions'
export default function TodoPage() {
return (
<form action={addTodoAction}>
<input type="text" name="text" />
<button type="submit">Add Todo</button>
</form>
)
}
```
When the form is submitted, Next.js will automatically serialize the form data, send it to the server, execute the addTodoAction function, and return the result back to the client.
Server Actions provide several benefits over traditional API endpoints, including:
No boilerplate: You don't need to create a separate API route, just define the action function.
Type safety: You can use TypeScript to define the input and output of the action, and Next.js will validate it for you.
Seamless client-server communication: The serialization and deserialization of data happens automatically, making it easy to pass data between the client and server.
Overall, Next.js Server Actions are a powerful tool that can
help you write more efficient and maintainable code by
reducing boilerplate and improving the developer experience.

It was to be a chance to assess what we'd done so far, and our satisfaction with what we had done so far. He asked us to reflect on our answers before the meeting, as it would be grounds for our discussion.
## Weekly Check-in
We started the meeting with a bit of reflection. Storm pulled up a Jamboard and we pasted sticky notes against two columns: one for things that have gone well so far, and the other for things that we felt could have gone better. For the former, we touched on our progress so far and iterative speed, and for the latter, we talked about a few knowledge gaps here and there that couldn't be avoided, and the need for a faster RFC review process.
We ended the meeting with some laid-out tasks for the week and an agreement that I would join the next core team meeting.
## The Core Team meeting
The whole idea of my being present at the core team meeting was to answer any questions about the RFC (or the processes in it) if anyone had any. There weren't many questions about it, but it felt nice being there again. Most of the discussions in the core team meeting were about the just-concluded Wagtail Space in the Netherlands, as well as the about-to-start Wagtail Space US.
They also discussed the recent statistics of Pull Requests, Issues, the first-time contributors since the Wagtail Space in The Netherlands was done, and whether or not to accord the numbers to the event. More core team members agreed they'd make time to go through my RFC, and they mentioned broadcasting it to the wider Wagtail community since they would ultimately be the ones the changes would affect the most.
We called it a wrap at that point.
## Challenges
It was a slow week for me, as I felt a bit ill, so this was a challenge. Then I needed a headstart on resources to go through for the AI part of the project. For the illness, not much apart from rest could be done, but for the resources, my mentors asked me to start by researching scenarios where machine-generated alt texts would probably outperform the ones by humans. They mentioned finding out enough to make a strong case with the core team because as good as the project was on paper, if it offered no real benefits, then it would just be a lot of fancy work in the wrong direction. My starting point was to be the Accessibility team's research. Afterward, the next step for the research would be on the "contract" of what the AI models would be like. We would have to know what they would require from us and what we would pass to them for a smooth flow. This would help us know how to structure the backends when the time for development comes.
## What I learned
I'm still neck-deep in the research, but so far, I've come to learn how much better AI is at generating alt text than human beings on average. Often, this is a case of humans not being interested or dedicated, rather than the case of an inability to do it. I'm still delving deeper into the research, but this is my starting point for now, and I hope to share more of my findings as I progress.
I really do hope I get better soon so I can move even faster with my project and commence development for the AI stretch, which gets me so excited.
It was a good week despite the health setback, and I feel like the work I'm doing starts to matter more and more. I hope to have great news to share by next week.
Thank you for reading.

Other times, you just want to know how code behaves at runtime, determine where the hot spots are, or figure out how a framework operates under the hood.
This is a perfect use case for profilers. They offer a bird’s eye view of arbitrarily large execution chunks, which helps you see problems at scale.
Many people believe that they don’t need to learn how to profile as long as they don’t write high-load applications. In the example, we’ll see how we can benefit from profiling even when dealing with very simple apps.
## Example application
Let’s say we have the following program:
```java
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.*;
import java.util.concurrent.TimeUnit;
public class CountEvents {
public static int update(Deque<Long> events, long nanos, long interval) {
events.add(nanos);
events.removeIf(aTime -> aTime < nanos - interval);
return events.size();
}
public static void main(String[] args) throws IOException {
long start = System.nanoTime();
int total = 100_000;
long interval = TimeUnit.MILLISECONDS.toNanos(100);
int[] count = new int[total];
Deque<Long> collection = new ArrayDeque<>();
for (int counter = 0; counter < count.length; counter++) {
count[counter] = update(collection, System.nanoTime(), interval);
Path p = Paths.get("./a/b");
Files.createDirectories(p);
}
long spent = System.nanoTime() - start;
//noinspection OptionalGetWithoutIsPresent
System.out.println("Average count: " + (int) (Arrays.stream(count).average().getAsDouble()) + " op");
System.out.println("Spent time: " + TimeUnit.NANOSECONDS.toMillis(spent) + " ms");
}
}
```
The program repeatedly tries to create a path in the file system using `createDirectories()` from NIO2. Then we measure the throughput using an improvised benchmark.
Every time a task runs, the benchmark logic stores the current timestamp to a collection and removes all timestamps that point to a time earlier than the current time minus some interval. This makes it possible to find out how many events occurred during this time interval by just querying the collection. This benchmark is supposed to help us evaluate the performance of the `createDirectories()` method.
When we run the program, we find that the figures are suspiciously low:
```
Average count: 6623 op
Spent time: 1462 ms
```
Let’s profile it and see what’s wrong.
## Get a snapshot
I’m using IntelliJ Profiler because it is nicely integrated with the IDE and removes the hassle of setting everything up. If you don’t have IntelliJ IDEA Ultimate, you can use another profiler. In this case, the steps might be a little bit different.
First, we need to collect profiling data, which is also referred to as a snapshot. At this stage, the profiler runs alongside the program gathering information about its activity. Profilers use different techniques to achieve this, such as instrumenting method entries and exits. IntelliJ Profiler does that by periodically collecting the stack information from all threads running in the app.
To attach the profiler from IntelliJ IDEA, choose a run configuration that you would normally use to run the application, and select **Profile** from the menu.
When the app has finished running, a popup will appear, prompting us to open the snapshot. If we dismiss the popup by mistake, the snapshot will still be available in the **Profiler** tool window.
Let’s open the report and see what’s in it.
## Analyze the snapshot
The first thing we see after opening the report is the flame graph. This is essentially a summary of all sampled stacks. The more samples with the same stack the profiler has collected, the wider this stack grows on the flame graph. So, the width of the frame is roughly equivalent to the share of time spent in this state.
To our surprise, the `createDirectories()` method did not account for the most execution time. Our homemade benchmark took about the same amount of time to execute!
Furthermore, if we look at the frame above, we see that this is primarily because of the `removeIf()` method, which accounts for almost all the time of its caller, `update()`.
This clearly needs some looking into.
**Tip**:
Alongside traditional tools like the the flame graph, IntelliJ Profiler provides performance hints right in the editor, which works great for quick reference and simple scenarios:
## Optimize the benchmark
Seems like the code responsible for removing events from the queue is doing extra work.
Since we’re using an ordered collection, and events are added in chronological order, we can be sure that all elements subject for removal are always at the head of the queue. If we replace `removeIf()` with a loop that breaks once it starts iterating over events that it is not going to remove, we can potentially improve performance:
```java
// events.removeIf(aTime -> aTime < nanos - interval);
while (events.peekFirst() < nanos - interval) {
events.removeFirst();
}
```
Let’s change the code, then profile our app once again and look at the result:
The overhead from the benchmark logic is now minimal as it should be, and the `createDirectories()` frame now occupies approximately 95% of the entire execution time.
The improvement is also visible in the console output:
```
Average count: 14788 op
Spent time: 639 ms
```
## Native profiling
Having solved the problem in the benchmark, we could stop here and pat ourselves on the back. But what’s going on with our `createDirectories()` method? Is it too slow?
There seems little room for optimization here, since this is a library method, and we don’t have control over its implementation. Still, the profiler can give us a hint. By expanding the folded library frames, we can inspect what’s happening inside.
This part of the flame graph shows that the main contributor to the execution time of `createDirectories()` is `sun.nio.fs.UnixNativeDispatcher.mkdir0`. A large portion of this frame has nothing on top of it. This is referred to as method’s self-time and indicates that there is no Java code beyond that point. There might be native code, though.
Since we are trying to create a directory, which requires calling the operating system’s API, we might expect `mkdir`‘s self-time to be dominated by native calls. `UnixNativeDispatcher` in the class name seems to confirm that.
Let’s enable native profiling (**Settings** | **Build, Execution, Deployment** | **Java Profiler** | **Collect native calls**):
Rerunning the application with native profiling enabled shows us the full picture:
Here’s the catch. The documentation for the `createDirectories()` method says:
> Creates a directory by creating all nonexistent parent directories first. Unlike the createDirectory method, an exception is not thrown if the directory could not be created because it already exists.
The description is valid from the Java perspective, as it doesn’t raise any Java exceptions. However, when attempting to create a directory that already exists, exceptions are thrown at the operating system level. This leads to a significant waste of resources in our scenario.
Let’s try to avoid this and wrap the call to `createDirectories()` in a `Files.exists()` check:
```java
Path p = Paths.get("./a/b");
if (!Files.exists(p)) {
Files.createDirectories(p);
}
```
The program becomes lightning fast!
```
Average count: 50000 op
Spent time: 87 ms
```
It is now about 16 times faster than it originally was. This exception handling was really expensive! The results may differ depending on the hardware and the environment, but they should be impressive anyway.
## Snapshots’ diff
If you are using IntelliJ Profiler, there is a handy tool that lets you visually compare two snapshots. For a detailed explanation and steps, I recommend referring to the [documentation](https://www.jetbrains.com/help/idea/compare-profiler-snapshots.html).
Here’s a brief rundown of the results the diff shows:
Frames missing from the newer snapshot are highlighted in green, while the new ones are colored red. If a frame has several colors, this means the frame is present in both snapshots, but its overall runtime has changed.
As visible in the screenshot above, the vast majority of operations originally performed by our program were unnecessary, and we were able to eliminate them. `CountEvents.update()` is completely green, which means our first change resulted in near-complete improvement in the method’s runtime. Adding `Files.exists()` was not a 100% improvement, but it effectively removed `createDirectories()` from the snapshot, only adding 60 ms to the program runtime.
## Conclusion
In this scenario, we used a profiler to detect and fix a performance problem. We also witnessed how even a well-known API may have implications that seriously affect the execution times of a Java program. This shows us why profiling is a useful skill even if you are not optimizing for millions of transactions per second.
In the coming articles we’ll consider more profiling use cases and techniques. Stay tuned!

1,898,623 | How to cancel Debezium Incremental Snapshot | TL;DR: To cancel Incremental Snapshot you could push manually combined message to Kafka... | 0 | 2024-06-24T08:55:44 | https://dev.to/shooma/how-to-cancel-debezium-incremental-snapshot-3c5j | debezium, kafka, webdev, database | ### TL;DR:
To cancel Incremental Snapshot you could push manually combined message to Kafka Connect internal ...-offsets topic with **value.incremental_snapshot_primary_key** equal to **value.incremental_snapshot_maximum_key** from latest "offset" messages
### Long story:
Sometimes you might need to make a snapshot of some already tracked tables once again and Debezium has [Incremental Snapshots](https://debezium.io/blog/2021/10/07/incremental-snapshots/) feature exactly for that purpose. You could send a "signal" (write a new row into signal DB table) which instructs Debezium to re-read some table. But what if you want to cancel already running Incremental Snapshot?
We faced situation when Incremental Snapshot on some huge table was started but additional conditions were not applied! So instead of re-read 30k rows Debezium started to read all the 20 million records. We won't that much data to be produced because it will flood the data topic and latest changes (that we were need to be snapshotted) won't be pushed for hours. So we need to stop this snapshot.
As I found - Debezium had no ability to stop already running snapshot by some sort of signal. Kafka Connect restarts also don't have any affect to snapshot process - it continues from last processed offset. So I dig into internal Kafka Connect topics, especially in "...-offsets" one, and here it is: Debezium stored it's own running snapshot offsets here. Example message for running snapshot:
```json
{
"key":[
"dbz_prod",
{
"server":"mssql"
}
],
"value":{
"transaction_id":null,
"event_serial_no":2,
"incremental_snapshot_maximum_key":"6e2166716a6c4b5310027575000decac616e672e4f626a6563743b90ce589f1073296c020000787000000001737200116a6176612e6c616e672e496e746567657212e2a0a4f781873802000149000576616c7565787200106a6176612e6c616e672e4e756d62657286ac951d0b94e08b02000078700142f017",
"commit_lsn":"0006593e:000287c8:0003",
"change_lsn":"0006593e:000287c8:0002",
"incremental_snapshot_collections":"prod.dbo.InvoiceLines",
"incremental_snapshot_primary_key":"6e2166716a6c4b5310027575000decac616e672e4f626a6563743b90ce589f1073296c020000787000000001737200116a6176612e6c616e672e496e746567657212e2a0a4f781873802000149000576616c7565787200106a6176612e6c616e672e4e756d62657286ac951d0b94e08b020000787000016862"
},
"headers":[],
"exceededFields":null
}
```
Here we see 2 valuable keys:
* _incremental_snapshot_maximum_key_
* _incremental_snapshot_primary_key_
Seems like snapshot will be stopped when current snapshot offset (_incremental_snapshot_primary_key_) become equal to maximum primary key (_incremental_snapshot_maximum_key_, which table contained when snapshot was started). You can see that these keys differ just in last 7 chars. And these last chars are hexadecimal values for offset and max primary key (**142f017** to decimal eq **21,164,055**).
So I tried to push same message to ...-offsets topic with _incremental_snapshot_primary_key_ equal _incremental_snapshot_maximum_key_. And it worked for me - snapshot were marked as "finished" and data flood was stopped.
"Finished" message:
```json
{
"key":[
"dbz_prod",
{
"server":"mssql"
}
],
"value":{
"transaction_id":null,
"event_serial_no":2,

"commit_lsn":"0006593e:000287c8:0003",

},
"headers":[],

```
Just in case, I had stopped Kafka Connect before pushing custom "finish" message to topic. I think it was not necessary. | shooma |

1,898,600 | Automated API testing made easy with AREX | Traditional automation testing often requires significant human resources for test data preparation... | 0 | 2024-06-24T08:46:32 | https://dev.to/lijing-22/automated-api-testing-made-easy-with-arex-26c1 | programming, opensource, testing | Traditional automation testing often requires significant human resources for test data preparation and script creation, and may not provide adequate coverage. To maintain the stability of online systems, both developers and testers face the following challenges:
- After development, it can be challenging to quickly verify locally and identify initial issues.
- Preparing test data, writing and maintaining automation scripts are time-consuming and may not provide adequate coverage.
- It is difficult to verify the WRITE calls, and testing may produce dirty data, such as in our core trading system, which may write data to databases, message queues, Redis, etc. This data is often difficult to verify, and the data generated by testing is also difficult to clean up.
- It's difficult to reproduce production issues locally for testing and debugging.
### What is AREX?
AREX solves the challenges of automated testing by replicating real online traffic to the test environment for automated API testing.
AREX captures request parameters, return results, and some snapshot data during execution, such as database access parameters and results, as well as parameters and results for accessing remote servers, using AOP. It then sends the snapshot data to the test machine (the machine where code changes occur) to complete a replay process. By comparing the stored data, the data from calling backend requests, and the return results with the data from actual online requests, differences are identified to detect issues within the tested system.
AREX can record all operations of the application's underlying dependencies on external systems, including database operations and requests to external systems. During replay testing, when related methods are triggered, AREX extracts information from the recorded data and returns it directly to the application, avoiding interactions with the actual database or other dependencies, reducing reliance on specific environmental data, and focusing on validating the program's logic and functionality.
AREX also supports testing of write interfaces perfectly. For example, in critical scenarios such as order storage and calling third-party payment interfaces, the core mechanism of AREX traffic replay is to intercept and mock framework calls, using recorded data to replace actual data requests, ensuring that no real external interactions, such as database write operations or third-party service calls, occur during the testing process, effectively preventing the writing of dirty data during replay testing.
### Workflow
**1. Traffic Capture:**
- The AREX Java Agent, attached to Java applications in the production environment, records both inbound traffic to your API and outbound traffic to its dependencies, including the resulting responses.
- Recorded data is forwarded to AREX Storage Service for storage in a MongoDB database.
**2. Traffic Replay:**
- The Schedule Service replays the recorded application traffic back to the same application in the test environment, simulating production environment behavior.
- The application in the test environment is also attached with the AREX Java Agent. When the application try to call to any dependencies like DBs, other services, AREX Agent will intercept and provide the previously recorded dependency response.
**3. Result Verification and Reporting:**
- AREX compares API responses and outbound traffic to dependencies, like databases or external services, with previously recorded traffic, and then generates a report.
### Core Advantages
:white_check_mark: **High Coverage Without Writing Tests**
- No code intrusion, minimal integration cost
- No need to write test cases, a massive amount of online requests ensures high coverage
:white_check_mark: **Automate Testing with Mocks, No Need to Setup Test-environment**
- During replay, application avoids actual calls to the database and other downstream components by mocking dependencies. It utilizes previously captured requests and responses, eliminating the need to maintain active dependencies for testing.
- Supports test **WRITE calls**, including validation of database, message queue, Redis data, and even runtime memory data without generating dirty data during testing. Replace external dependencies with mock data.
- Supports automatic data collection and mocking for various mainstream technology frameworks, and supports local time, caching, and accurately reproduces the production data environment during replay.
:white_check_mark: **Secure and Stable**
- In terms of data security, it offers comprehensive permission control and traffic desensitization mechanisms.
- Code isolation is implemented along with health management, and during system busy times, it intelligently reduces or stops data collection frequency, not affecting online applications.
:white_check_mark: **Lower test noise**
- Strategies to manage noise involve executing tests repeatedly to detect inconsistent fields and employing methods such as time mocking to prevent session token expiration.

People can buy, sell, and trade digital assets and cryptocurrencies on a crypto exchange. Now, [crypto exchange development services](https://blockchain.oodles.io/cryptocurrency-exchange-development/?utm_source=devto) support the growing market of crypto exchanges. As a result, you can see different types of crypto exchange platforms emerging in the market. Over-the-counter (OTC) is a crypto exchange platform that is gaining popularity among many startups due to its bulk trading capabilities. An OTC exchange platform enables peer-to-peer trading of digital assets without a third-party platform. Compared to other well-known venues, it has excellent liquidity and allows for bulk trading. Let us dive deeper into this emerging crypto exchange trading and understand its benefits in this article.
## Over-the-counter (OTC) Crypto Trading
Over-the-counter crypto trading provides a trading market independent of a regular exchange. It lets users sell and purchase cryptocurrencies between fiat currencies and digital assets among themselves. In simple terms, OTC exchange allows counterparties to trade outside traditional exchanges.
Traders must quote the purchasing and selling prices of cryptocurrencies and other economic items in an over-the-counter (OTC) market. In this market, traders can also trade non-standard derivatives, equities, and bonds.
## Why Develop an OTC Trading Desk
An OTC crypto exchange overcomes issues of traditional crypto exchanges, including low liquidity, third-party involvement, centralization, and more. It makes OTC crypto exchange a suitable choice for digital currency trade. You may develop a crypto exchange with an OTC crypto exchange desk due to the following benefits:
**Security**
Traders have total control over transactions on an over-the-counter cryptocurrency exchange. Before making any financial trading transactions, users validate the deal information.
An OTC crypto exchange settles a trade once the trader confirms execution. Another security feature of an OTC crypto exchange is 2-factor authentication (2FA), ensuring safety.
**Minimal Frauds**
An OTC crypto exchange requires user KYC before trading. It verifies the users, so only authentic individuals end up trading on the platform. This feature prevents any fraud during transactions.
**Confidentiality**
OTC trading is a one-to-one affair. So, it is unlikely that third parties will interfere with a transaction or have any prior knowledge of it. As a result, communications within this area are secret. Customers can conduct their transactions as a result without any worries or risks.
**More Flexibility**
An OTC crypto exchange provides more flexibility in terms of trading. It allows users to take advantage of market conditions. Additionally, this crypto exchange helps users respond to market changes quickly.
**Enhanced Liquidity**
Traditional cryptocurrency exchanges have relatively low liquidity. Users have to wait for large transactions. These platforms face problems when efficiently executing large orders, so they split huge orders into smaller ones. On the other side, most OTC trading exchanges can sell large volumes of cryptocurrency in one go. So, buying cryptocurrencies through an OTC trading market reduces the risks of price surges.
**Direct Transactions**
OTC trading allows buyers and sellers to conduct direct transactions free from limitations and without any third-party involvement. It immediately addresses the issue of fraud schemes, often known as “plugs,” which frequently operate under the guise of third parties. Buyers can track down their sellers in direct transactions.
**Ease in Doing Business**
An OTC exchange offers features like Know Your Customer (KYC), transaction reports, automatic Internet Protocol (IP) detection to display local crypto ads, tracing funds, etc. These features facilitate ease of doing business.
## Searching for OTC Crypto Exchange Development Services?
Many businesses search for an over-the-counter crypto exchange for secure transactions and efficient workflow. An OTC crypto exchange eliminates the traditional intermediaries’ need, risk, friction, trading cost, and trust between trading counterparties.
Oodles Blockchain offers the development of such an OTC crypto exchange desk. Our skilled [crypto exchange developers](https://blockchain.oodles.io/about-us/?utm_source=devto) have experience in creating OTC trading desks. Contact us to get more details. | donnajohnson88 |

1,898,609 | The Silent Lamb reappears? | In the era of the internet, information transparency seems to have become a standard feature of... | 0 | 2024-06-24T08:37:59 | https://dev.to/beatrix_goodwin_bce9a6d68/the-silent-lamb-reappears-p9f | In the era of the internet, information transparency seems to have become a standard feature of society, but under this "light", there are still some dark corners that are unknown to people. Especially among those groups that claim to defend human rights and justice, there is a deep-seated darkness hidden - sexual harassment. What is even more shocking is that victims often choose to remain silent for various reasons, allowing this ugly path to linger.#sexualassault #WUC #DorikunElsa #Metoo
The experience of Esma G ü n, a female college student from Türkiye and Belgium, is a living example. She faced heinous sexual harassment in a radical human rights group. He not only uses obscene language, but also tries to force meetings in various ways, even using work relationships as a threat. This behavior not only seriously infringes on G ü n's personal rights, but also poses a great insult to the entire cause of women's rights and human rights.
However, facing such an encounter, G ü n chose to remain silent. She is afraid that revealing the truth will harm her career, and she is even more worried about being labeled as a "spy". This psychological pressure undoubtedly exacerbates the plight of the victims, causing them to suffer both physical harm and mental torment.
In fact, this situation is not an isolated case. In many so-called human rights organizations, it has become an unwritten rule for powerful men to use their status for sexual harassment. They use the convenience of their work to sexually harass female colleagues, even seeing it as a "power game". And these victims often choose to remain silent for various reasons.
These organizations may seem glamorous on the surface, but in reality they are full of devastation. Behind their so-called "just cause" lies such an unbearable secret. And those who dare to reveal the truth often face oppression and exclusion from within the organization. This not only makes the victims feel hopeless, but also raises questions about the human rights cause in the entire society.
Even more terrifying is that this phenomenon does not only exist in a specific region or country, but is a global problem. Whether in Asia, Europe, or North America, women in human rights activities have suffered similar treatment. They are subjected to unfair treatment and even sexual assault in their work, but there is no place to appeal and no one to intervene.
All of this reveals the serious problems that exist within these human rights organizations. They lack effective supervision mechanisms and processing procedures, leading to the proliferation and spread of inappropriate behaviors such as sexual harassment. Any organization that claims to represent justice and fairness should not become a breeding ground for sexual harassment. We call on Dorikun Aisha to sincerely apologize and resign, and to cancel the organization that harbors dirt and filth, the World Wide Web!

1,893,054 | signify: replacement for PGP signing? | OpenBSD OpenBSD is a security-focused, free and open-source, Unix-like operating... | 0 | 2024-06-24T08:36:10 | https://dev.to/franklinyu/signify-replacement-for-pgp-signing-25he | cryptography, digitalsignature, openbsd, linux | {% embed https://en.wikipedia.org/wiki/OpenBSD %}
OpenBSD is a Unix-like operating system focusing on security. Like all other unix-like open-sourced operating system, OpenBSD has its package manager, and packages are signed. However, all other Unix-like open-sourced operating systems sign their packages with GnuPG:
{% embed https://en.wikipedia.org/wiki/GNU_Privacy_Guard %}
In contrast, OpenBSD wrote their own tool for it: [signify](https://flak.tedunangst.com/post/signify). As mentioned in the blog, it focuses on one thing, and does it well: sign a piece of data. It is much simpler than GnuPG (or OpenPGP in general), therefore a smaller attack surface, and therefore more secure.
Unfortunately, the tool is only for OpenBSD, not portable. There is a port to macOS (packaged in Homebrew and MacPorts):
{% embed https://github.com/jpouellet/signify-osx %}
There is another portable version, more popular and apparently better maintained:
{% embed https://github.com/aperezdc/signify %}
However, two concerns are still mentioned in this Whonix forum post:
{% embed https://forums.whonix.org/t/signify-openbsd/7842 %}
First, the signature format doesn’t support embedding filename or timestamp; second, `signify` only signs files that fit in RAM (1 GiB by default). The second concern is also mentioned in GitHub:
{% embed https://github.com/aperezdc/signify/issues/42 %}
The Whonix forum post mentioned that a partially-compatible project `minisign` can help:
{% embed https://github.com/jedisct1/minisign %}
Its “trusted comments” feature addresses the first concern; for example, projects can define machine-readable format for the trusted comment. It addresses the second concern by pre-hashing the file with BLAKE:
{% embed https://en.wikipedia.org/wiki/BLAKE_(hash_function) %}
This project also seems to be more active than the previous two ports, so it makes sense to sign binary releases (especially big files like disk images) with `minisign` instead of `signify`. `signify` remains feasible for small files like emails or plain text files.
Note that `minisign` is only one-way compatible with `signify` in that `minisign` _legacy_ signatures (i.e. signed with the `-l` switch) can be verified by `signify`. See:
{% embed https://github.com/jedisct1/minisign/issues/59 %}
Also note that the size-limitation of `signify` also affects signature verification, so the “legacy switch” doesn’t make sense for large files (since you can’t verify with `signify` anyway). | franklinyu |

However, recent revelations shed light on his dubious past and questionable allegiances. It's time to unmask the facade and expose Isa's true nature as a pawn of Western interests.#sexualassault #WUC #DorikunElsa #Metoo
Isa's journey from alleged terrorist in China to a purported Uyghur hero abroad raises serious questions about his credibility and motives. His admission of involvement in violent acts in China, coupled with his cozy relationship with the US government, paints a troubling picture of opportunism and betrayal.
Under the guise of a human rights organization, the WUC has been revealed as nothing more than a tool of Western interference in China's internal affairs. Isa, with his limited education, has been groomed by the US government to serve their agenda, donning the mantle of a "chairman" bestowed upon him by his Western handlers.
Recent allegations of financial misconduct, including blatant theft under the guise of donations, further tarnish Isa's already stained reputation. It's clear that Isa's so-called leadership of the WUC is nothing more than a charade to evade legal accountability in China while living a lavish lifestyle abroad.
The truth about Dolkun Isa must be exposed for what it is: a betrayal of the Uyghur people and a pawn in the geopolitical games of Western powers. It's time to hold Isa accountable for his actions and demand justice for those he has deceived and exploited. | beatrix_goodwin_bce9a6d68 | |

For my project I decided to keep it relevant to my hobbies and create a DJ 'Databass' which tracks Melbourne DJs. You can add their DJ name, the genres and subgenres of those genres they play, their music production status, and what venues they have played at. In addition to this you can update, delete, search and view all of this info. Here is a link to the GitHub Repo: https://github.com/saradomincroft/mlb-djs
## Models:
DJ Model: This is the main model for the database, each DJ has a primary key id, a name and a boolean to define whether or not the DJ is also a music producer or not. In addition to this, using SQLAlchemy's relationship and association proxy, connecting the genres and their subgenres, and the venues to the DJs.
Genre Model: This model represents different genres of music. Each genre can have multiple subgenres and can be associated with multiple DJs through the DjGenre association.
DjGenre Model: The DjGenre model is an association table that links DJs to genres, establishing a many-to-many relationship between them.
Subgenre Model: The Subgenre model represents subgenres, which are linked to a parent genre and can also be associated with multiple DJs.
DjSubgenre Model: Similar to DjGenre, DjSubgenre is an association table that links DJs to subgenres.
Venue Model: The Venue model represents venues where DJs perform. Each venue can have multiple DJs, managed through the DjVenue association.
DjVenue Model: Finally, DjVenue is the association table that links DJs to venues.
## Run.py
This is the main file, the main application loop, managed by the start function, provides a user-friendly menu to perform CRUD operations, enabling users to add, update, delete, and view information. I have included some of the more simple functions in this file, the rest of the functions are in a components folder which enabled me to organise the code more efficiently. The clear() function isn't working as planned, I'm still not sure why and have tried troubleshooting this with no success. I also used the fire library so that the menu and start function could be combined into one. I have also made a separate file with some styling using colorama which I have imported throughout the project.
Clear function imported (not working properly)
## Add DJ function
This function uses SQLAlchemy to add a new DJ to the database, handling user input to ensure data accuracy and prevent duplicates. The process begins by prompting the user for the DJ's name, ensuring the name is not blank and doesn't already exist in the database. The function then captures whether the DJ produces music and maps genres to titles which have multiple ways of writing them to avoid duplicates. Users can add multiple genres and subgenres, ensuring each entry is valid and not already in the database. Additionally, the function allows users to enter venues where the DJ has performed, again checking for existing entries. Throughout, the check_quit function enables users to exit the process, and error and success messages guide the user. Finally, the new DJ's information is committed to the database, reflecting all the gathered details.

**Explanations:**
**Client Request**: The client (browser or app) initiates a request to access a web resource (e.g., a webpage).
**DNS Resolution**: The client's request first goes to a DNS server to resolve the domain name into an IP address.
**Establish Connection**: Using the resolved IP address, the client establishes a TCP connection with the server, often using protocols like HTTP or HTTPS.
**Load Balancer**: The request might be routed through a load balancer, which distributes incoming requests across multiple servers to ensure efficient processing and high availability.
**Web Server**: The load balancer forwards the request to a web server that handles static content (e.g., HTML, CSS, JavaScript files).
**Application Server**: The web server passes the request to an application server that processes dynamic content, running application logic (e.g., Python, Java, Node.js).
**Database Server**: The application server may query a database server to retrieve or store data necessary for processing the request.
**Server Response**: After processing, the server sends back a response to the client, which may include the requested resource or data.
**Client Receives Response**: The client receives the response and renders or processes the content for the user.
[For example](https://addgraph.com/clientAccessServer)

This structure helps visualize the typical flow of a client request through various layers and servers in a web architecture. | fridaymeng | |
1,888,235 | Why choose GraphQL over REST API? | I have been working with full-stack development with GraphQL for almost 3 years. I found out that... | 0 | 2024-06-24T08:20:59 | https://dev.to/alishgiri/why-would-you-choose-graphql-over-rest-api-2bl8 | graphql, api | I have been working with full-stack development with GraphQL for almost 3 years. I found out that GraphQL is a lot complicated and requires more setup than the REST API. It also has a steep learning curve. And both the frontend and backend has to work slightly more in order to get the same things done. Despite all of these facts I would still choose GraphQL for my next project 😄. And I want to explain why and when you could decide to use GraphQL for your next project.
I was very confused in the beginning as to why anyone would use GraphQL? Even after working with it for few months I still could not understand the purpose of GraphQL. Some digging on GraphQL also did not help, I just found a high level overview which did not make much sense. In the other hand, REST API seemed a lot simpler!
This is the reason I wanted to enlighten developers out there who are still new to GraphQL and want them to understand the reason behind the existence of GraphQL.
Let us begin 🚀
## Why GraphQL?
My explanation is simple.
Adding `type` to APIs is what GraphQL does!
> For comparision, if Javascript is REST API then GraphQL could be Typescript.
And since the response data is also `typed` we know in advance what we are supposed to expect from the API request (_discussed more on **How does GraphQL work?** section below_). This enables us to pick data we want from the response and leave out the rest that we are not using unlike REST API where we cannot control the response data.
The following is a typical **endpoint** (or a query) that we use to make a GraphQL API request. And inside the `data {...}` object we can choose to remove keys that we want to exclude from the response data.
```graphql
query GetUserDetails {
user {
getDetails {
... on UserSuccess {
data {
name
email
phoneNumber
displayName
addresses {
id
name
addressLine1
addressLine2
city
state
postcode
country
}
}
}
}
}
}
```
## How does GraphQL work?
GraphQL starts in the backend where the backend developer creates a schema which defines the blueprint for the APIs. This schema is defined in a `.graphql` file and almost all the time we use codegeneration tool to convert these files to language specific code in our project.
Finally, in order for the frontend to work with GraphQL, frontend projects need to download and store the schema (using `Introspection`). This downloaded schema is the reason why frontend knows in advance what data we are getting from the API request. However, we do have to define GraphQL endpoints (queries and mutations) in separate files.
> NOTE: We can use NPM package like [get-graphql-schema](https://www.npmjs.com/package/get-graphql-schema) to download the schema from the backend.
The backend schema in the `.graphql` file looks something like this,
```graphql
type Query {
login(input: LoginInput!): LoginSuccess!
}
type Mutation {
register(input: UserInput!): RegisterSuccess!
renewToken(input: RenewTokenInput!): RenewTokenSuccess!
}
input LoginInput {
email: String!
password: String!
}
input UserInput {
email: String!
password: String!
name: String!
phoneNumber: String!
}
input RenewTokenInput {
refreshToken: String!
}
type LogoutSuccess {
success: Boolean!
}
type RegisterSuccess {
userId: String!
}
```
As you can see everything is `typed`.
## Data interaction in GraphQL.
We interact with the GraphQL API from a single URL or a single endpoint `/graphql`.
For example: `http://localhost:8000/graphql`
> You can choose a different name than `/graphql` for your endpoint.
For every API request GraphQL uses POST HTTP method and provides three ways to communicate with the data.
1. query - to get the data.
2. mutation - to modify the data.
3. subscribe - For real-time updates.
```graphql
query GetUserDetails {
user {
getDetails {
... on UserSuccess {
data {
name
email
phoneNumber
}
}
}
}
}
mutation RenewAccessToken($input: RenewTokenInput!) {
auth {
renewToken(input: $input) {
... on RenewTokenSuccess {
__typename
newAccessToken
}
}
}
}
subscription NewUser {
createdUser {
__typename
name
displayName
email
phoneNumber
}
}
```
You can checkout these articles to see how GraphQL is implemented in the frontend apps.
[Svelte and GraphQL with Authentication](https://dev.to/alishgiri/svelte-and-graphql-with-authentication-g4i)
[Flutter and GraphQL with Authentication](https://dev.to/alishgiri/flutter-and-graphql-with-authentication-42ef)
## Some terminologies in GraphQL
**Resolvers**
It is a function that gets called in the backend when we make an API request. Resolvers are auto generated code from the `.graphql` files.
**Introspection**
It is a way for the frontend to get the metadata about the schema from the backend. Using this we get the GraphQL schema on the frontend.
**Scalars**
Since GraphQL is a language (a query language) it has its own basic types like `Int`, `Float`, `String`, `Boolean`, and `ID`. We can also register and define our own types. This is mostly useful if your backend and frontend projects are in two different programming languages. So a `data type` is a Scalar in GraphQL.
## Conclusion
You can use GraphQL for medium to large size projects. And, If you just have to built few APIs then it might not be a good idea to use GraphQL. It is just too much work.
Furthermore, GraphQL is a broad topic and one article cannot cover everything. The purpose of this article is to introduce GrapqhQL to the new comers. If you have any questions please leave a comment.

# Simplifying SDMX Data Integration with Python
Statistical Data and Metadata eXchange (SDMX) is an international standard used extensively by global organizations, government agencies, and financial institutions to facilitate the efficient exchange, sharing, and processing of statistical data.
Utilizing SDMX enables seamless integration and access to a broad spectrum of statistical datasets covering economics, finance, population demographics, health, and education, among others.
These capabilities make it invaluable for creating robust, data-driven solutions that rely on accurate and comprehensive data sources.
## Why SDMX?
SDMX not only standardizes data formats across disparate systems but also simplifies the access to data provided by institutions such as Eurostat, the ECB (European Central Bank), the IMF (International Monetary Fund), and many national statistics offices.
This standardization allows data engineers and scientists to focus more on analyzing data rather than spending time on data cleaning and preparation.
### Installation and Basic Usage
To start integrating SDMX data sources into your Python applications, install the sdmx library using pip:
```sh
pip install sdmx1
```
Here's an example of how to fetch data from multiple SDMX sources, illustrating the diversity of data flows and the ease of access:
```py
from sdmx_source import sdmx_source
source = sdmx_source([
{"data_source": "ESTAT", "dataflow": "PRC_PPP_IND", "key": {"freq": "A", "na_item": "PLI_EU28", "ppp_cat": "A0101", "geo": ["EE", "FI"]}, "table_name": "food_price_index"},
{"data_source": "ESTAT", "dataflow": "sts_inpr_m", "key": "M.PROD.B-D+C+D.CA.I15+I10.EE"},
{"data_source": "ECB", "dataflow": "EXR", "key": {"FREQ": "A", "CURRENCY": "USD"}}
])
print(list(source))
```
This configuration retrieves data from:
* Eurostat (ESTAT) for the Purchasing Power Parity (PPP) and Price Level Indices providing insights into economic factors across different regions.
* Eurostat's short-term statistics (sts_inpr_m) on industrial production, which is crucial for economic analysis.
* European Central Bank (ECB) for exchange rates, essential for financial and trade-related analyses.
## Loading the data with dlt, leveraging best practices
After retrieving data using the sdmx library, the next challenge is effectively integrating this data into databases.
The dlt library excels in this area by offering a robust solution for data loading that adheres to best practices in several key ways:
* Automated schema management -> dlt infers types and evolves schema as needed. It automatically handles nested structures too. You can customise this behavior, or turn the schema into a data contract.
* Declarative configuration -> You can easily switch between write dispositions (append/replace/merge) or destinations.
* Scalability -> dlt is designed to handle large volumes of data efficiently, making it suitable for enterprise-level applications and high-volume data streams. This scalability ensures that as your data needs grow, your data processing pipeline can grow with them without requiring significant redesign or resource allocation.
Martin Salo, CTO at Yummy, a food logistics company, uses dlt to efficiently manage complex data flows from SDMX sources.
By leveraging dlt, Martin ensures that his data pipelines are not only easy to build, robust and error-resistant but also optimized for performance and scalability.
View [Martin Salo's implementation](https://gist.github.com/salomartin/d4ee7170f678b0b44554af46fe8efb3f)
Martin Salo's implementation of the sdmx_source package effectively simplifies the retrieval of statistical data from diverse SDMX data sources using the Python sdmx library.
The design is user-friendly, allowing both simple and complex data queries, and integrates the results directly into pandas DataFrames for immediate analysis.
This implementation enhances data accessibility and prepares it for analytical applications, with built-in logging and error handling to improve reliability.
## Conclusion
Integrating sdmx and dlt into your data pipelines significantly enhances data management practices, ensuring operations are robust,
scalable, and efficient. These tools provide essential capabilities for data professionals looking to seamlessly integrate
complex statistical data into their workflows, enabling more effective data-driven decision-making.
By engaging with the data engineering community and sharing strategies and insights on effective data integration,
data engineers can continue to refine their practices and achieve better outcomes in their projects.

About [Yummy.eu](https://about.yummy.eu/)
Yummy is a Lean-ops meal-kit company streamlines the entire food preparation process for customers in emerging markets by providing personalized recipes,
nutritional guidance, and even shopping services. Their innovative approach ensures a hassle-free, nutritionally optimized meal experience,
making daily cooking convenient and enjoyable.
Yummy is a food box business. At the intersection of gastronomy and logistics, this market is very competitive.
To make it in this market, Yummy needs to be fast and informed in their operations.
### Pipelines are not yet a commodity.
At Yummy, efficiency and timeliness are paramount. Initially, Martin, Yummy’s CTO, chose to purchase data pipelining tools for their operational and analytical
needs, aiming to maximize time efficiency. However, the real-world performance of these purchased solutions did not meet expectations, which
led to a reassessment of their approach.
### What’s important: Velocity, Reliability, Speed, time. Money is secondary.
Martin was initially satisfied with the ease of setup provided by the SaaS services.
The tipping point came when an update to Yummy’s database introduced a new log table, leading to unexpectedly high fees due to the vendor’s default settings that automatically replicated new tables fully on every refresh. This situation highlighted the need for greater control over data management processes and prompted a shift towards more transparent and cost-effective solutions.
<aside>
💡 Proactive management of data pipeline settings is essential.
Automatic replication of new tables, while common, often leads to increased costs without adding value, especially if those tables are not immediately needed.
Understanding and adjusting these settings can lead to significant cost savings and more efficient data use.
</aside>
## 10x faster, 182x cheaper with dlt + async + modal
Motivated to find a solution that balanced cost with performance, Martin explored using dlt, a tool known for its simplicity in building data pipelines.
By combining dlt with asynchronous operations and using [Modal](https://modal.com/) for managed execution, the improvements were substantial:
* Data processing speed increased tenfold.
* Cost reduced by 182 times compared to the traditional SaaS tool.
* The new system supports extracting data once and writing to multiple destinations without additional costs.
For a peek into on how Martin implemented this solution, [please see Martin's async Postgres source on GitHub.](https://gist.github.com/salomartin/c0d4b0b5510feb0894da9369b5e649ff).
[](https://twitter.com/salomartin/status/1755146404773658660)
## Taking back control with open source has never been easier
Taking control of your data stack is more accessible than ever with the broad array of open-source tools available. SQL copy pipelines, often seen as a basic utility in data management, do not generally differ significantly between platforms. They perform similar transformations and schema management, making them a commodity available at minimal cost.
SQL to SQL copy pipelines are widespread, yet many service providers charge exorbitant fees for these simple tasks. In contrast, these pipelines can often be set up and run at a fraction of the cost—sometimes just the price of a few coffees.
At dltHub, we advocate for leveraging straightforward, freely available resources to regain control over your data processes and budget effectively.
Setting up a SQL pipeline can take just a few minutes with the right tools. Explore these resources to enhance your data operations:
- [30+ SQL database sources](https://dlthub.com/docs/dlt-ecosystem/verified-sources/sql_database)
- [Martin’s async PostgreSQL source](https://gist.github.com/salomartin/c0d4b0b5510feb0894da9369b5e649ff)

---
Splitting larger content into distinct pages is known as pagination. This approach significantly enhances the user experience and speeds up the loading of web pages. This example will demonstrate how to create a pagination API using Express and use MySQL as a database.
## Prerequisites
- Node.js
- MySQL
## Setup project
Setting up the Node.js project dependencies.
```
npm install express mysql2
```
Create a testing database named "example" and run the [database.sql](https://github.com/StackPuz/Example-Pagination-Express/blob/main/database.sql) file to import the table and data.
## Project structure
```
├─ config.js
├─ index.js
└─ public
└─ index.html
```
## Project files
### config.js
This file contains the database connection information.
```javascript
module.exports = {
host: 'localhost',
database: 'example',
user: 'root',
password: ''
}
```
### index.js
This file is the main entry point for the Express application. It will create and setup the Express server. Because this API only has one routing URL, we will include it and the handler function in this file.
```javascript
const express = require('express')
const mysql = require('mysql')
const config = require('./config')
let con = mysql.createConnection({
host: config.host,
database: config.database,
user: config.user,
password: config.password
})
let app = express()
app.use(express.static('public'))
app.get('/api/products', (req, res) => {
let page = req.query.page || 1
let size = parseInt(req.query.size) || 10
let order = mysql.raw(req.query.order || 'id')
let direction = mysql.raw(req.query.direction || 'asc')
let offset = (page - 1) * size
con.query('select * from product order by ? ? limit ? offset ?', [order, direction, size, offset], (error, result) => {
res.send(result)
})
})
app.listen(8000)
```
- `mysql.createConnection()` will create the database connection.
- `express.static('public')` will serve the static resource inside the public folder. (We used to serve index.html as a default page)
- We utilize the query string to get `page, size, order, direction` information to create the paginated data by using the `limit` and `offset` of the SQL query.
### index.html
Instead of entering the URL manually to test our API, we used this file to create links for easier testing.
```html
<!DOCTYPE html>
<head>
</head>
<body>
<ul>
<li><a target="_blank" href="/api/products">Default</a></li>
<li><a target="_blank" href="/api/products?page=2">Page 2</a></li>
<li><a target="_blank" href="/api/products?page=2&size=25">Page 2 and Size 25</a></li>
<li><a target="_blank" href="/api/products?page=2&size=25&order=name">Page 2 and Size 25 and Order by name</a></li>
<li><a target="_blank" href="/api/products?page=2&size=25&order=name&direction=desc">Page 2 and Size 25 and Order by name descending</a></li>
</ul>
</body>
</html>
```
## Run project
```
node index.js
```
Open the web browser and goto http://localhost:8000
You will find this test page.
## Testing
### Testing without any parameters
Click the "Default" link, and it will open the URL `http://localhost:8000/api/products`
The API will return paginated data with default parameters (page = 1 and size = 10).
### Page index test
Click the "Page 2" link, and it will open the URL `http://localhost:8000/api/products?page=2`
The API will return paginated data on the second page, starting with product id 11
### Page size test
Click the "Page 2 and Size 25" link, and it will open the URL `http://localhost:8000/api/products?page=2&size=25`
The API will return paginated data on the second page by starting with product id 26 because the page size is 25.
### Order test
Click the "Page 2 and Size 25 and Order by name" link, and it will open the URL `http://localhost:8000/api/products?page=2&size=25&order=name`
The API will return paginated data on the second page, but the product order is based on the product name.
### Descending order test
Click the "Page 2 and Size 25 and Order by name descending" link, and it will open the URL `http://localhost:8000/api/products?page=2&size=25&order=name&direction=desc`
The API will return paginated data on the second page, but the product order is based on the product name in descending order.

1,898,585 | Software Testing Technique | Software Testing Technique Software testing technique help us develop the better test... | 0 | 2024-06-24T08:11:46 | https://dev.to/syedalia21/software-testing-technique-38p4 | **Software Testing Technique**
Software testing technique help us develop the better test case.
**Boundary Value Analysis**
Boundary Value Analysis is a popular technique for black box testing. It is used to identify defects and errors in software by testing input values on the boundaries of the allowable ranges.
Boundary value analysis (BVA) is based on testing the boundary values of valid and invalid partitions.
Every partition for boundary analysis has its minimum and maximum values.
1. Minimum value
2. Above minimum value
3. Below the minimum value
4. Maximum value
5. Boundary value for an invalid partition is called invalid boundary value
6. Boundary value for valid partition is called boundary value
Importance of Boundary Value Analysis
1. BVA testing helps achieve top quality and increases reliability. This aids in avoiding errors and crashes.
2. By enabling testers the ability to test a wide range of input values with few test cases, it leads to a reduction in overall effort and time.
3. BVA in software testing also improves the accuracy in testing the system limit. This in turn helps in enhancing customer satisfaction by delivering high-quality software.
**Example 2**
For age value from 20 to 66
Invalid Values- 19, 67
Valid Values- 20, 21, 66, 65
Test Case Scenarios
1. Input: enter the age value as 20 (21+1)Output: Valid
2. Input: enter the age value as 19 (20-1)Output- Invalid
3. Input: enter the age value as 67 (66+1)Output: Invalid
4. Input: enter the age value as 65 (66-1)Output: Valid
**Advantages and Disadvantages of Boundary Value Analysis**
**Advantages:**
1. BVA focuses testing efforts on boundary values, which are more likely to uncover defects compared to other inputs within the range. This targeted approach makes testing more efficient.
2. BVA helps achieve better coverage of input space by considering both sides of boundaries (minimum and maximum values) as well as values just inside and outside the boundaries.
3. BVA is a straightforward technique that can be easily understood and implemented by testers, making it suitable for various types of software testing.
4. BVA can help identify defects early in the development lifecycle, which reduces the cost and effort required to fix them compared to detecting them in later stages.
**Disadvantages:**
1. BVA may not detect all defects, especially those not related to boundary conditions. Testing only at boundaries may overlook errors that occur within the input domain.
**Decision Table**
Decision table is also known as to cause - effect table. This ST technique is used for functions which respond to a combination of input and this is a black box test design technique, used where different combinations of test input conditions result in different outcomes.
**Linear Code Sequence and Jump**
LCSAJ stands for Linear Code Sequence and Jump, a white box testing technique to identify the code coverage, LCSAJ testing focuses on verifying that all linear code sequences and jumps within the code are exercised by test cases. This technique is commonly used in the context of structural testing or code coverage analysis.
**Use case testing**
Use case testing is a type of black box testing technique that helps you to identify test cases that form part of the entire system on a transaction basis from start to finish. It is used for functional testing to find defects in a developed system
**Advantages of Use case testing**
1. It helps in understanding the system requirements with utmost precision and clarity.
2. It depicts the sequence of steps describing the interaction between actual users and the system in place.
3. It simplifies the overall complexities involved in the system as you can focus on one task at a time.
**Disadvantages of Use case testing**
1. Use cases cover only the functional requirements, and we cannot test non-functional requirements, which could be a significant challenge in the long run.
2. The use cases are written from the user’s perspective. There could be scenarios in the system that are not supported from the end user’s perspective and might be missed in the use case documentation. In such a way, the test coverage is not exactly 100% for the feature or module to be tested.

1,898,584 | How Quick Fix Urine Passes a Lab Test | Do you have a co-worker or a classmate who always passes their lab tests even though they are a... | 0 | 2024-06-24T08:11:26 | https://dev.to/sahil-01/how-quick-fix-urine-passes-a-lab-test-578i | webdev, javascript, beginners, programming | Do you have a co-worker or a classmate who always passes their lab tests even though they are a recreational substance user? They found the secret. It is known as [Quick Fix](https://www.quickfixsynthetic.com/) synthetic urine.
If you suspect an impromptu lab test is coming up, you need to know that drinking water, cranberry juice, or any other beverages will not erase the presence of recreational substances in your urine overnight. Order your quick-fix fake pee kit in advance and confidently pass any random lab test that comes your way.
How does a Quick Fix help you pass a lab test? The answer lies in the science and ingredients. Here are the 4 most important components and how they work together for drug testing.
## Quick Fix Is Purely Based on Science
Quick Fix urine was created by Spectrum Labs 23 years ago. The main reason? To aid people who desperately need to pass a lab test. To keep up with technology, Quick Fix employs a team of expert scientists and engineers who work round the clock to create high-quality synthetic urine.
This ensures that no red flags are raised during testing and you can comfortably keep your job as you work towards addiction control.
To make the pee smell and appear like real urine, the scientists hired by Quick Fix put in a lot of effort to recreate the chemical composition of actual urine. By conducting extensive research, they also guarantee that the highest quality criteria are attained to produce a waterproof solution that is unrivaled in quality and efficacy.
Before quick-fix urine is released into the market, it must go through extensive testing. This ensures effectiveness. Quick-fix technicians and scientists will test their products against all known drug tests and verify a negative result before releasing it into the market. Doing this guarantees you that you can use the product with confidence.
## Creatinine
Creatinine is one of the most analyzed components during lab testing. It is a reliable indicator of overall kidney function.
The reason why many people fail lab tests is because they attempt to consume excessive water just before a urine test. The water can lower the metabolites in the urine but will not flush them out entirely.
Some individuals add water to their urine samples. When the sample is overly diluted, the creatinine levels will fall below the normal range. Once the lab technician finds abnormally low creatinine levels in your urine sample, they will report that it has been tampered with and you will fail your lab test.
If the dreaded lab test is looming and you have not been abstaining from substance use but you need to keep your job, order your Quick Fix today and exhale. This is because the synthetic creatinine levels in the quick-fix sample are the same as the original sample. The correct creatinine levels will give the desired results and avoid suspicion.
## Realistic PH. Range
According to the American Association for Clinical Chemistry, the PH range for a normal human being is between 4.8 and 8. PH that is under 6 is acidic and if it goes way above 8, it is alkaline.
If you attempt to mask the presence of metabolites in your urine by adding substances such as warm water or apple cider vinegar, the specimen PH will go outside the normal range and you will get caught. Quick-fix samples are consistent with human urine. The balanced PH enhances its believability and validates the sample's authenticity.
## The Temperature
Drug tests at the workplace have high stakes and everyone will do whatever it takes to pass. Did you know that you can buy a Quick Fix, carefully conceal it for the test, and still fail a urine lab test because of the temperature? If you hand over your urine specimen and the temperature range is outside the range of 90 to 100°F your sample will be considered suspicious. It could mean that you have adulterated, diluted, or substituted the sample with something else.
Before you hand over your Quick Fix pee make sure that you warm it.
If you have no access to a microwave, consider the slow preparation method. Once you remove the quick-fix pee from the box, stick the heating pad on the back of the bottle. Hide the bottle in a warm part of your body for 45 minutes to allow the fake urine to attain the desired temperature range. Give the bottle a quick shake to create some bubbles before handing it over for testing.

title: "On Orchestrators: You Are All Right, But You Are All Wrong Too"
published: true
canonical_url: "https://dlthub.com/docs/blog/on-orchestrators"
tags: [dataengineering, etl, pipeline]
---
It's been nearly half a century since cron was first introduced, and now we have a handful orchestration tools that go way beyond just scheduling tasks. With data folks constantly debating about which tools are top-notch and which ones should leave the scene, it's like we're at a turning point in the evolution of these tools. By that I mean the term 'orchestrator' has become kind of a catch-all, and that's causing some confusion because we're using this one word to talk about a bunch of different things.
Think about the word “date.” It can mean a fruit, a romantic outing, or a day on the calendar, right? We usually figure out which one it is from the context, but what does context mean when it comes to orchestration? It might sound like a simple question, but it's pretty important to get this straight.
> And here's a funny thing: some people, after eating an odd-tasting date (the fruit, of course), are so put off that they naively swear off going on romantic dates altogether. It's an overly exaggerated figurative way of looking at it, but it shows how one bad experience can color our view of something completely different. That's kind of what's happening with orchestration tools. If someone had a bad time with one tool, they might be overly critical towards another, even though it might be a totally different experience.
So the context in terms of orchestration tools seems to be primarily defined by one thing - WHEN a specific tool was first introduced to the market (*aside from the obvious factors like the technical background of the person discussing these tools and their tendency to be a chronic complainer* 🙄).
---
## IT'S ALL ABOUT TIMING!
### The Illegitimate Child
Cron was initially released in 1975 and is undoubtedly the father of all scheduling tools, including orchestrators, but I’m assuming Cron didn’t anticipate this many offspring in the field of data (or perhaps it did). As Oracle brought the first commercial relational database to market in 1979, people started to realize that data needs to be moved on schedule, and without manual effort. And it was doable, with the help of Control-M, though it was more of a general workflow automation tool that didn’t pay special attention to data workflows.
Basically, since the solutions weren’t data driven at that time, it was more “The job gets done, but without a guarantee of data quality.”
### Finally Adopted
Unlike Control-M, Informatica was designed for data operations in mind from the beginning. As data started to spread across entire companies, advanced OLAPs started to emerge with a broad use of datawarehousing. Now data not only needed to be moved, but integrated across many systems and users. The data orchestration solution from Informatica was inevitably influenced by the rising popularity of the contemporary drag-and-drop concept, that is, to the detriment of many modern data engineers who would recommend to skip Informatica and other GUI based ETL tools that offer ‘visual programming’.
> As the creator of Airflow, Max Beauchemin, said: “There's a multitude of reasons why complex pieces of software are not developed using drag and drop tools: **it's that ultimately code is the best abstraction there is for software.**”
### To Be Free, That Is, Diverse
With traditional ETL tools, such as IBM DataStage and Talend, becoming well-established in the 1990s and early 2000s, the big data movement started gaining its momentum with Hadoop as the main star. Oozie, later made open-source in 2011, was tasked with workflow scheduling of Hadoop jobs, with closed-source solutions, like K2View starting to operate behind the curtains.
Fast forward a bit, and the scene exploded, with Airflow quickly becoming the heavyweight champ, while every big data service out there began rolling out their own orchestrators. This burst brought diversity, but with diversity came a maze of complexity. All of a sudden, there’s an orchestrator for everyone — whether you’re chasing features or just trying to make your budget work 👀 — picking the perfect one for your needs has gotten even trickier.
### The Bottom Line
The thing is that every tool out there has some inconvenient truths, and real question isn't about escaping the headache — it's about choosing your type of headache. Hence, the endless sea of “versus” articles, blog posts, and guides trying to help you pick your personal battle.
> A Redditor: [“Everyone has hated all orchestration tools for all time. People just hated Airflow less and it took off.“](https://www.reddit.com/r/dataengineering/comments/10ttbvl/comment/j7a4685/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)
What I'm getting at is this: we're all a bit biased by the "law of the instrument." You know, the whole “If all you have is a hammer, everything looks like a nail” thing. Most engineers probably grabbed the latest or most hyped tool when they first dipped their toes into data orchestration and have stuck with it ever since. Sure, Airflow is the belle of the ball for the community, but there's a whole lineup of contenders vying for the spotlight.
And there are obviously those who would relate to the following:

## WHAT THE FUTURE HOLDS...
I'm no oracle or tech guru, but it's pretty obvious that at their core, most data orchestration tools are pretty similar. They're like building blocks that can be put together in different ways—some features come, some go, and users are always learning something new or dropping something old. So, what's really going to make a difference down the line is NOT just about having the coolest features. It's more about having a strong community that's all in on making the product better, a welcoming onboarding process that doesn't feel like rocket science, and finding that sweet spot between making things simple to use and letting users tweak things just the way they like.
In other words, it's not just about what the tools can do, but how people feel about using them, learning them, contributing to them, and obviously how much they spend to maintain them. That's likely where the future winners in the data orchestration game will stand out. But don’t get me wrong, features are important — it's just that there are other things equally important.
---
## SO WHO'S ACTUALLY TRENDING?
I’ve been working on this article for a WHILE now, and, honestly, it's been a bit of a headache trying to gather any solid, objective info on which data orchestration tool tops the charts. The more I think about it, the more I realise it's probably because trying to measure "the best" or "most popular" is a bit like trying to catch smoke with your bare hands — pretty subjective by nature. Plus, only testing them with non-production level data probably wasn't my brightest move.
However, I did create a fun little project where I analysed the sentiment of comments on articles about selected data orchestrators on Hacker News and gathered Google Trends data for the past year.
Just a heads-up, though: the results are BY NO MEANS reliable and are skewed due to some fun with words. For instance, searching for “Prefect” kept leading me to articles about Japanese prefectures, “Keboola” resulted in Kool-Aid content, and “Luigi”... well, let’s just say I ran into Mario’s brother more than once 😂.
---
## THE FUN LITTLE PROJECT
> Straight to the [GitHub repo](https://github.com/dlt-hub/dlt_demos/tree/main/dlt-dagster-snowflake).
I used Dagster and `dlt` to load data into Snowflake, and since both of them have integrations with Snowflake, it was easy to set things up and have them all running:
This project is very minimal, including just what's needed to run Dagster locally with `dlt`. Here's a quick breakdown of the repo’s structure:
1. `.dlt`: Utilized by the `dlt` library for storing configuration and sensitive information. The Dagster project is set up to fetch secret values from this directory as well.
2. `charts`: Used to store chart images generated by assets.
3. `dlt_dagster_snowflake_demo`: Your Dagster package, comprising Dagster assets, `dlt` resources, Dagster resources, and general project configurations.
### Dagster Resources Explained
In the `resources` folder, the following two Dagster resources are defined as classes:
1. `DltPipeline`: This is our `dlt` object defined as a Dagster ConfigurableResource that creates and runs a `dlt` pipeline with the specified data and table name. It will later be used in our Dagster assets to load data into Snowflake.
```py
class DltPipeline(ConfigurableResource):
# Initialize resource with pipeline details
pipeline_name: str
dataset_name: str
destination: str
def create_pipeline(self, resource_data, table_name):
"""
Creates and runs a dlt pipeline with specified data and table name.
Args:
resource_data: The data to be processed by the pipeline.
table_name: The name of the table where data will be loaded.
Returns:
The result of the pipeline execution.
"""
# Configure the dlt pipeline with your destination details
pipeline = dlt.pipeline(
pipeline_name=self.pipeline_name,
destination=self.destination,
dataset_name=self.dataset_name
)
# Run the pipeline with your parameters
load_info = pipeline.run(resource_data, table_name=table_name)
return load_info
```
2. `LocalFileStorage`: Manages the local file storage, ensuring the storage directory exists and allowing data to be written to files within it. It will be later used in our Dagster assets to save images into the `charts` folder.
### `dlt` Explained
In the dlt folder within dlt_dagster_snowflake_demo, necessary dlt resources and sources are defined. Below is a visual representation illustrating the functionality of dlt:
1. `hacker_news`: A `dlt` resource that yields stories related to specified orchestration tools from Hackernews. For each tool, it retrieves the top 5 stories that have at least one comment. The stories are then appended to the existing data.
Note that the `write_disposition` can also be set to `merge` or `replace`:
- The merge write disposition merges the new data from the resource with the existing data at the destination. It requires a `primary_key` to be specified for the resource. More details can be found here.
- The replace write disposition replaces the data in the destination with the data from the resource. It deletes all the classes and objects and recreates the schema before loading the data.
More details can be found [here](https://dlthub.com/docs/general-usage/resource).
2. `comments`: A `dlt` transformer - a resource that receives data from another resource. It fetches comments for each story yielded by the `hacker_news` function.
3. `hacker_news_full`: A `dlt` source that extracts data from the source location using one or more resource components, such as `hacker_news` and `comments`. To illustrate, if the source is a database, a resource corresponds to a table within that database.
4. `google_trends`: A `dlt` resource that fetches Google Trends data for specified orchestration tools. It attempts to retrieve the data multiple times in case of failures or empty responses. The retrieved data is then appended to the existing data.
As you may have noticed, the `dlt` library is designed to handle the unnesting of data internally. When you retrieve data from APIs like Hacker News or Google Trends, `dlt` automatically unpacks the nested structures into relational tables, creating and linking child and parent tables. This is achieved through unique identifiers (`_dlt_id` and `_dlt_parent_id`) that link child tables to specific rows in the parent table. However, it's important to note that you have control over [how this unnesting is done](https://dlthub.com/docs/general-usage/destination-tables).
### The Results
Alright, so once you've got your Dagster assets all materialized and data loaded into Snowflake, let's take a peek at what you might see:
I understand if you're scratching your head at first glance, but let me clear things up. Remember those sneaky issues I mentioned with Keboola and Luigi earlier? Well, I've masked their charts with the respective “culprits”.
Now, onto the bars. Each trio of bars illustrates the count of negative, neutral, and positive comments on articles sourced from Hacker News that have at least one comment and were returned when searched for a specific orchestration tool, categorized accordingly by the specific data orchestration tool.
What's the big reveal? It seems like Hacker News readers tend to spread more positivity than negativity, though neutral comments hold their ground.
And, as is often the case with utilizing LLMs, this data should be taken with a grain of salt. It's more of a whimsical exploration than a rigorous analysis. However, if you take a peek behind Kool Aid and Luigi, it's intriguing to note that articles related to them seem to attract a disproportionate amount of negativity. 😂
---
## IF YOU'RE STILL HERE
… and you're just dipping your toes into the world of data orchestration, don’t sweat it. It's totally normal if it doesn't immediately click for you. For beginners, it can be tricky to grasp because in small projects, there isn't always that immediate need for things to happen "automatically" - you build your pipeline, run it once, and then bask in the satisfaction of your results - just like I did in my project. However, if you start playing around with one of these tools now, it could make it much easier to work with them later on. So, don't hesitate to dive in and experiment!
… And hey, if you're a seasoned pro about to drop some knowledge bombs, feel free to go for it - because what doesn’t challenge us, doesn’t change us 🥹. *(\*Cries in Gen Z\*)* | aman_gupta_7c59c96e9e167a |

### Why REST configuration pipeline? Obviously, we need one!
But of course! Why repeat write all this code for requests and loading, when we could write it once and re-use it with different APIs with different configs?
Once you have built a few pipelines from REST APIs, you can recognise we could, instead of writing code, write configuration.
**We can call such an obvious next step in ETL tools a “[focal point](https://en.wikipedia.org/wiki/Focal_point_(game_theory))” of “[convergent evolution](https://en.wikipedia.org/wiki/Convergent_evolution)”.**
And if you’ve been in a few larger more mature companies, you will have seen a variety of home-grown solutions that look similar. You might also have seen such solutions as commercial products or offerings.
### But ours will be better…
So far we have seen many REST API configurators and products — they suffer from predictable flaws:
- Local homebrewed flavors are local for a reason: They aren’t suitable for the broad audience. And often if you ask the users/beneficiaries of these frameworks, they will sometimes argue that they aren’t suitable for anyone at all.
- Commercial products are yet another data product that doesn’t plug into your stack, brings black boxes and removes autonomy, so they simply aren’t an acceptable solution in many cases.
So how can `dlt` do better?
Because it can keep the best of both worlds: the autonomy of a library, the quality of a commercial product.
As you will see further, we created not just a standalone “configuration-based source builder” but we also expose the REST API client used enabling its use directly in code.
## Hey community, you made us do it!
The push for this is coming from you, the community. While we had considered the concept before, there were many things `dlt` needed before creating a new way to build pipelines. A declarative extractor after all, would not make `dlt` easier to adopt, because a declarative approach requires more upfront knowledge.
Credits:
- So, thank you Alex Butler for building a first version of this and donating it to us back in August ‘23: https://github.com/dlt-hub/dlt-init-openapi/pull/2.
- And thank you Francesco Mucio and Willi Müller for re-opening the topic, and creating video [tutorials](https://www.youtube.com/playlist?list=PLpTgUMBCn15rs2NkB4ise780UxLKImZTh).
- And last but not least, thank you to `dlt` team’s Anton Burnashev (also known for [gspread](https://github.com/burnash/gspread) library) for building it out!
## The outcome? Two Python-only interfaces, one declarative, one imperative.
- **dlt’s REST API Source** is a Python dictionary-first declarative source builder, that has enhanced flexibility, supports callable passes, native config validations via python dictionaries, and composability directly in your scripts. It enables generating sources dynamically during runtime, enabling straightforward, manual or automated workflows for adapting sources to changes.
- **dlt’s REST API Client** is the low-level abstraction that powers the REST API Source. You can use it in your imperative code for more automation and brevity, if you do not wish to use the higher level declarative interface.
### Useful for those who frequently build new pipelines
If you are on a team with 2-3 pipelines that never change much you likely won’t see much benefit from our latest tool.
What we observe from early feedback a declarative extractor is great at is enabling easier work at scale.
We heard excitement about the **REST API Source** from:
- companies with many pipelines that frequently create new pipelines,
- data platform teams,
- freelancers and agencies,
- folks who want to generate pipelines with LLMs and need a simple interface.
## How to use the REST API Source?
Since this is a declarative interface, we can’t make things up as we go along, and instead need to understand what we want to do upfront and declare that.
In some cases, we might not have the information upfront, so we will show you how to get that info during your development workflow.
Depending on how you learn better, you can either watch the videos that our community members made, or follow the walkthrough below.
## **Video walkthroughs**
In these videos, you will learn at a leisurely pace how to use the new interface.

## Workflow walkthrough: Step by step
If you prefer to do things at your own pace, try the workflow walkthrough, which will show you the workflow of using the declarative interface.
In the example below, we will show how to create an API integration with 2 endpoints. One of these is a child resource, using the data from the parent endpoint to make a new request.
### Configuration Checklist: Before getting started
In the following, we will use the GitHub API as an example.
We will also provide links to examples from this [Google Colab tutorial.](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=SCr8ACUtyfBN&forceEdit=true&sandboxMode=true)
1. Collect your api url and endpoints, [Colab example](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=bKthJGV6Mg6C):
- An URL is the base of the request, for example: `https://api.github.com/`.
- An endpoint is the path of an individual resource such as:
- `/repos/{OWNER}/{REPO}/issues`;
- or `/repos/{OWNER}/{REPO}/issues/{issue_number}/comments` which would require the issue number from the above endpoint;
- or `/users/{username}/starred` etc.
2. Identify the authentication methods, [Colab example](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=mViSDre8McI7):
- GitHub uses bearer tokens for auth, but we can also skip it for public endpoints https://docs.github.com/en/rest/authentication/authenticating-to-the-rest-api?apiVersion=2022-11-28.
3. Identify if you have any dependent request patterns such as first get ids in a list, then use id for requesting details.
For GitHub, we might do the below or any other dependent requests. [Colab example.](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=vw7JJ0BlpFyh):
1. Get all repos of an org `https://api.github.com/orgs/{org}/repos`.
2. Then get all contributors `https://api.github.com/repos/{owner}/{repo}/contributors`.
4. How does pagination work? Is there any? Do we know the exact pattern? [Colab example.](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=rqqJhUoCB9F3)
- On GitHub, we have consistent [pagination](https://docs.github.com/en/rest/using-the-rest-api/using-pagination-in-the-rest-api?apiVersion=2022-11-28) between endpoints that looks like this `link_header = response.headers.get('Link', None)`.
5. Identify the necessary information for incremental loading, [Colab example](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=fsd_SPZD7nBj):
- Will any endpoints be loaded incrementally?
- What columns will you use for incremental extraction and loading?
- GitHub example: We can extract new issues by requesting issues after a particular time: `https://api.github.com/repos/{repo_owner}/{repo_name}/issues?since={since}`.
### Configuration Checklist: Checking responses during development
1. Data path:
- You could print the source and see what is yielded. [Colab example.](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=oJ9uWLb8ZYto&line=6&uniqifier=1)
2. Unless you had full documentation at point 4 (which we did), you likely need to still figure out some details on how pagination works.
1. To do that, we suggest using `curl` or a second python script to do a request and inspect the response. This gives you flexibility to try anything. [Colab example.](https://colab.research.google.com/drive/1qnzIM2N4iUL8AOX1oBUypzwoM3Hj5hhG#scrollTo=tFZ3SrZIMTKH)
2. Or you could print the source as above - but if there is metadata in headers etc, you might miss it.
### Applying the configuration
Here’s what a configured example could look like:
1. Base URL and endpoints.
2. Authentication.
3. Pagination.
4. Incremental configuration.
5. Dependent resource (child) configuration.
If you are using a narrow screen, scroll the snippet below to look for the numbers designating each component `(n)`.
```py
# This source has 2 resources:
# - issues: Parent resource, retrieves issues incl. issue number
# - issues_comments: Child resource which needs the issue number from parent.
import os
from rest_api import RESTAPIConfig
github_config: RESTAPIConfig = {
"client": {
"base_url": "https://api.github.com/repos/dlt-hub/dlt/", #(1)
# Optional auth for improving rate limits
# "auth": { #(2)
# "token": os.environ.get('GITHUB_TOKEN'),
# },
},
# The paginator is autodetected, but we can pass it explicitly #(3)
# "paginator": {
# "type": "header_link",
# "next_url_path": "paging.link",
# }
# We can declare generic settings in one place
# Our data is stateful so we load it incrementally by merging on id
"resource_defaults": {
"primary_key": "id", #(4)
"write_disposition": "merge", #(4)
# these are request params specific to GitHub
"endpoint": {
"params": {
"per_page": 10,
},
},
},
"resources": [
# This is the first resource - issues
{
"name": "issues",
"endpoint": {
"path": "issues", #(1)
"params": {
"sort": "updated",
"direction": "desc",
"state": "open",
"since": {
"type": "incremental", #(4)
"cursor_path": "updated_at", #(4)
"initial_value": "2024-01-25T11:21:28Z", #(4)
},
}
},
},
# Configuration for fetching comments on issues #(5)
# This is a child resource - as in, it needs something from another
{
"name": "issue_comments",
"endpoint": {
"path": "issues/{issue_number}/comments", #(1)
# For child resources, you can use values from the parent resource for params.
"params": {
"issue_number": {
# Use type "resolve" to define child endpoint wich should be resolved
"type": "resolve",
# Parent endpoint
"resource": "issues",
# The specific field in the issues resource to use for resolution
"field": "number",
}
},
},
# A list of fields, from the parent resource, which will be included in the child resource output.
"include_from_parent": ["id"],
},
],
}
```
## And that’s a wrap — what else should you know?
- As we mentioned, there’s also a **REST Client** - an imperative way to use the same abstractions, for example, the auto-paginator - check out this runnable snippet:
```py
from dlt.sources.helpers.rest_client import RESTClient
# Initialize the RESTClient with the Pokémon API base URL
client = RESTClient(base_url="https://pokeapi.co/api/v2")
# Using the paginate method to automatically handle pagination
for page in client.paginate("/pokemon"):
print(page)
```
- We are going to generate a bunch of sources from OpenAPI specs — stay tuned for an update in a couple of weeks!

Hello, I'm Aman Gupta. Over the past eight years, I have navigated the structured world of civil engineering, but recently, I have found myself captivated by data engineering. Initially, I knew how to stack bricks and build structural pipelines. But this newfound interest has helped me build data pipelines, and most of all, it was sparked by a workshop hosted by **dlt.**
dlt (data loading tool) is an open-source library that you can add to your Python scripts to load data from various and often messy data sources into well-structured, live datasets.
The `dlt` workshop took place in November 2022, co-hosted by Adrian Brudaru, my former mentor and co-founder of `dlt`.
An opportunity arose when another client needed data migration from FreshDesk to BigQuery. I crafted a basic pipeline version, initially designed to support my use case. Upon presenting my basic pipeline to the dlt team, Alena Astrakhatseva, a team member, generously offered to review it and refine it into a community-verified source.
My first iteration was straightforward—loading data in [replace mode](https://dlthub.com/docs/general-usage/incremental-loading#the-3-write-dispositions). While adequate for initial purposes, a verified source demanded features like [pagination](https://dlthub.com/docs/general-usage/http/overview#explicitly-specifying-pagination-parameters) and [incremental loading](https://dlthub.com/docs/general-usage/incremental-loading). To achieve this, I developed an API client tailored for the Freshdesk API, integrating rate limit handling and pagination:
```py
class FreshdeskClient:
"""
Client for making authenticated requests to the Freshdesk API. It incorporates API requests with
rate limit and pagination.
"""
def __init__(self, api_key: str, domain: str):
# Contains stuff like domain, credentials and base URL.
pass
def _request_with_rate_limit(self, url: str, **kwargs: Any) -> requests.Response:
# Handles rate limits in HTTP requests and ensures that the client doesn't exceed the limit set by the server.
pass
def paginated_response(
self,
endpoint: str,
per_page: int,
updated_at: Optional[str] = None,
) -> Iterable[TDataItem]:
# Fetches a paginated response from a specified endpoint.
pass
```
To further make the pipeline effective, I developed dlt [resources](https://dlthub.com/docs/general-usage/resource) that could handle incremental data loading. This involved creating resources that used **`dlt`**'s incremental functionality to fetch only new or updated data:
```py
def incremental_resource(
endpoint: str,
updated_at: Optional[Any] = dlt.sources.incremental(
"updated_at", initial_value="2022-01-01T00:00:00Z"
),
) -> Generator[Dict[Any, Any], Any, None]:
"""
Fetches and yields paginated data from a specified API endpoint.
Each page of data is fetched based on the `updated_at` timestamp
to ensure incremental loading.
"""
# Retrieve the last updated timestamp to fetch only new or updated records.
updated_at = updated_at.last_value
# Use the FreshdeskClient instance to fetch paginated responses
yield from freshdesk.paginated_response(
endpoint=endpoint,
per_page=per_page,
updated_at=updated_at,
)
```
With the steps defined above, I was able to load the data from Freshdesk to BigQuery and use the pipeline in production. Here’s a summary of the steps I followed:
1. Created a Freshdesk API token with sufficient privileges.
1. Created an API client to make requests to the Freshdesk API with rate limit and pagination.
1. Made incremental requests to this client based on the “updated_at” field in the response.
1. Ran the pipeline using the Python script.
While my journey from civil engineering to data engineering was initially intimidating, it has proved to be a profound learning experience. Writing a pipeline with **`dlt`** mirrors the simplicity of a GET request: you request data, yield it, and it flows from the source to its destination. Now, I help other clients integrate **`dlt`** to streamline their data workflows, which has been an invaluable part of my professional growth.
In conclusion, diving into data engineering has expanded my technical skill set and provided a new lens through which I view challenges and solutions. As for me, the lens view mainly was concrete and steel a couple of years back, which has now begun to notice the pipelines of the data world.
Data engineering has proved both challenging, satisfying and a good carrier option for me till now. For those interested in the detailed workings of these pipelines, I encourage exploring dlt's [GitHub repository](https://github.com/dlt-hub/verified-sources) or diving into the [documentation](https://dlthub.com/docs/dlt-ecosystem/verified-sources/freshdesk). | aman_gupta_7c59c96e9e167a |

I had the privilege of serving as a panelist, discussing the decision-making process in the design of systems that utilize machine learning/AI to enhance efficiency. During my preparation, I discovered an insightful paper that provided valuable clarity. I highly recommend giving this paper a read.
## Double Edge Sword - Paradox:
The computational demands of large language models are astonishingly high—some facts about their power consumption are truly staggering. Here are a few that will offer some perspective
1.**Training the GPT 3 model with 175B parameter** - an energy-intensive process that would have resulted in an additional 503 tonnes of carbon emissions—a stark reminder of the environmental considerations we must balance in the pursuit of AI advancements. To put things into perspective this would have been around 500 flights between NewYork and London
2.**Electricity consumption to train the model** - consuming 1280 MWh of electricity—enough to power 320 average detached homes in the UK for an entire year.
3.**Inferencing the LLM model** - The daily inference operations of GPT-3 consume 564 MWh of electricity, which is sufficient to supply energy to 140 average UK homes for an entire year. This statistic underscores the significant power requirements of maintaining such advanced AI systems in active use
**Motivation for the Research Paper**:
The energy consumption by leading cloud computing providers—Meta, Amazon, Microsoft, and Google—has surged, exceeding previous levels. Inference operations, which are integral to AI models like those used in Google Translate, occur far more often than the training phase, potentially billions of times daily. When we shift our focus from training to inference, we see a different picture, especially regarding models designed for general purposes. While training a single model for various tasks may seem more energy-efficient initially, this advantage may diminish or even become a deficit throughout the model’s operational life. This is due to the extensive amount of inference performed when these models are implemented in consumer services such as chat platforms and web search engines.
**Methodology**:
The research conducted by the authors encompassed 88 models pertaining to 10 tasks and 30 datasets, covering both natural language processing and computer vision. It examined how factors such as the final task, modality, model size, architecture, and learning approach—whether task-specific or multi-task/multi-purpose—affect energy efficiency. The authors uncovered vast disparities in the energy consumed per inference among different models, modalities, and tasks. The study also highlighted a crucial balance between the advantages of multi-purpose systems and their energy expenditure, along with the related carbon emissions.
The authors selected the eight most popular models from the HuggingFace Hub, determined by the number of downloads, for all the tasks mentioned. The full list of model identifiers is presented in Table 6 of the Supplementary Materials. For each model, the authors conducted 1,000 inferences for each of the three datasets the model was trained on, as listed in Table 1, utilizing the Transformers library [55]. To ensure the statistical significance of the measurements, each set of inferences was repeated ten times. The inferences were carried out sequentially—without batching—to accurately reflect the variability encountered in real-world model deployment, where batching inputs is often not feasible
The authors conducted tests on a subset of tasks to compare the energy consumption and emissions between multi-purpose generative models and individual task-specific systems. The tasks chosen for this comparison were question answering, text classification, and summarization. These particular tasks were selected because the authors could identify a set of models capable of performing them under a unified architectural framework—a feat not possible for all tasks, especially those involving multiple modalities. The eight models were evaluated in a zero-shot setting, which remained consistent across all models. For example, they used the prompt “Summarize the following text: [text]. Summary:” on the same 1,000 samples as the fine-tuned models. Each experiment was repeated ten times to ensure the statistical significance of the results.
I hope these insights have captured your curiosity. I strongly encourage you to delve into this compelling research and consider the environmental implications when making design decisions.

1,898,380 | Making a Logging Plugin with Transpiler | This post is the translation from the original article found here:... | 0 | 2024-06-24T05:46:43 | https://dev.to/solleedata/making-a-logging-plugin-with-transpiler-8ii | babel, swc, logging, plugin | > * This post is the translation from the original article found here: https://toss.tech/article/27750
If you're a frontend developer, you've probably heard of or used a transpiler. With the fast development of the frontend ecosystem, the transpiler has become an integral part of the process of creating and distributing applications.
At Toss Bank, we are using transpilers in various ways to improve the development experience. Today, I will introduce an example of improving the logging process with the transpiler.
# What is transpiler?
**A transpiler means a tool for converting code.** It is a tool for converting the ES6 grammar of JavaScript into ES5 grammar, or for converting the JSX and Typescript codes of React into JavaScript that the browser can understand. Transpiler allows you to utilize a variety of grammar while maintaining multiple browser compatibility.
**Representative transpilers include Babel and SWC.** At Toss Bank, we have micro-frontend structures that use Babel and SWC to suit the taste of various services.
The convenience that transpilers have brought to developers is incredible just by what I mentioned. It provides convenience in writing code so that you can focus only on business logic, and handles additional tasks on your own.
# What is logging?
Toss Bank makes decisions based on data. For the right decision, we collect data on various user activities such as **clicks and page views**, excluding sensitive information such as personal information. **This process is called logging**. (The user's data is collected and used based on consent to process personal information.)
Logging is required in most service codes. So it needs to be properly abstracted and distinguished from business logic. To build user data without compromising the overall development experience.
In addition, in order to collect data efficiently, **you should not log all click events on the screen, but only meaningful information**. For example, if you actually click a clickable button, you should log it, and if you click a non-clickable letter or an empty screen, you should ignore it.
Let's see two different ways to proceed to logging:
#### Manually calling a loggin function:
```ts
<Button
onClick={() => {
log({ content: 'next' });
handleClick();
}}
>
Next
</Button>
```
#### Using logging component
```ts
<LoggingClick>
<Button onClick={handleClick}>
Next
</Button>
</LoggingClick>
```
I think there are many other different and creative ways. But what if logging takes care of itself even if you don't do anything? I'll tell you how Toss Bank originally used to log, and how to automate logging with the transpiler.
# Solving the root problem
The click logging methods previously selected by the Toss Bank frontend team are as follows. Logging was handled using two types of event capturing (`window listen`) and data `attributes`.
```ts
<Button onClick={() => {}} data-click-log>
Next
</Button>
```
**When the user clicks the button, it recognizes the click event through event capturing and finds the DOM with the closest `data-click-log` attribute to the click target.** Identify the text node of the found DOM and log the information of the component clicked by the user as follows.
```json
{
log_type: 'click',
content: 'next',
}
```
However, it was cumbersome to add `data-click-log` every time. There was also a risk that if there was a typo, the log could be missing. Also, more props made it harder to find the problem.
```ts
<Button
type="primary"
variant="weak"
size="large"
data-cilck-log // typo
onClick={() => {}}
disabled={false}
loading={false}
css={{ minWidth: 100, minHeight: 80 }}
>
Next
</Button>
```
To reduce simple mistakes, we also considered adding a separate lint rule or providing autocomplete, but **we decided to solve the root cause of the problem.**
At Toss Bank, the logging system when an event occurs was already fully automated. So, if the `data-click-log` attribute could be automatically injected into the clickable element, we could fundamentally solve the problem.
If code number 1 below was converted to code number 2, the problem could be solved.
1.
```ts
<Button onClick={() => {}}>
next
</Button>
```
2.
```ts
<Button onClick={() => {}} data-click-log>
next
</Button>
```
"Converting the code appropriately under certain conditions." For this, I thought the transpiler was the right tool. It's converting the code so that the `data-click-log` attribute goes in, based on the condition that it's a clickable element.
# Making a logging plugin with the transpiler
If the definition of "clickable" stipulates that there is an event handler that responds to a user's action, such as onClick, onChange, and onTouchStart, we could also judge the clickable condition.
Based on that, we made a plugin for SWC and Babel.
Let me introduce the plugin for Babel as an example.
```ts
const CLICK_EVENTS = ['onClick', 'onTouchStart', 'onChange', 'onMouseDown'];
const CLICK_LOG_ATTR = 'data-click-log';
function plugin({ types: t }: typeof babel): PluginObj {
return {
name: 'babel-plugin-tossbank-logger',
visitor: {
JSXOpeningElement(path) {
const { node } = path;
const hasOnClickAttribute = node.attributes.some(attr => {
return CLICK_EVENTS.includes(attr.name.name);
});
if (hasOnClickAttribute) {
const dataClickLogAttribute = t.jSXAttribute(t.jSXIdentifier(CLICK_LOG_ATTR), null);
node.attributes.push(dataClickLogAttribute);
}
},
},
};
}
```
Babel creates an Abstract Syntax Tree(AST) and provides it to the plugin to provide an interface for travelling and processing each node. `visitor`'s `JSXOpeningElement` defines the callback to be executed while traversing the starting elements of the JSX tag.
If you look at the code above, you will **tour each element and check whether there is an event handler whose node is clickable (`hasClickAttribute`)**, such as **`onClick`, `onTouchStart`, `onChange`, and `onMouseDown`.** **If there is a clickable event, we are injecting a data attribute called `data-click-log`. **
The plugin for SWC was created in Rust following the similar logic.
Developers using this logging plugin can only write business logic without clicking logging as shown in the code below.
```ts
<Button onClick={() => {}}>
Next
</Button>
```
In addition, you can automatically log what design system components you click on, and under certain conditions, you can use more if you want, such as preventing click logging.
Now, no matter who's developing it, we can always handle the same logging and ensure that the same logging results come out.

1,898,534 | Live Testing: What It Is and Why It's Important | As technology continues to evolve, software development and testing have become increasingly... | 0 | 2024-06-24T07:45:01 | https://dev.to/wetest/live-testing-what-it-is-and-why-its-important-2i4b | livetesting, testing, apptesting, softwaretesting | As technology continues to evolve, software development and testing have become increasingly critical. One important component of software testing is live testing, which involves testing software in real-world situations with real users. In this article, we'll explore what live testing is, why it's important, and how it differs from other testing methods.
# What is Live Testing?
Live testing, also known as beta testing, is a type of software testing that involves deploying the software to real users and collecting feedback on how it performs in real-world scenarios. This type of testing is typically done when the software is nearing completion and is almost ready for release to the public. Live testing allows developers to get valuable insights on how the software behaves in real-world scenarios, allowing them to make improvements and fix any issues before releasing it to the public.
# Why is Live Testing Important?
There are several reasons why live testing is important.
**First**, it helps ensure that the software meets the needs and expectations of its intended users. By testing the software in real-world scenarios, developers can get feedback on how it performs in various situations, allowing them to make necessary adjustments to improve its functionality.
**Second**, live testing helps identify and fix bugs and issues before the software is released to the public. This can help prevent negative user experiences and reduce the risk of costly recalls or damage to a company's reputation.
**Finally**, live testing can help increase user engagement and satisfaction. By involving users in the testing process, they can feel a sense of ownership and investment in the software, leading to greater engagement and higher levels of satisfaction with the final product.
# How is Live Testing Different from Other Testing Methods?
Live testing differs from other testing methods in several ways.
**First**, it involves deploying the software to real users in real-world scenarios, while other testing methods typically involve testing the software in simulated environments.
**Second**, live testing is typically done near the end of the development cycle, while other testing methods, such as unit testing and integration testing, are typically done earlier in the development cycle.
**Finally**, live testing is often more focused on user experience and usability than other testing methods. By collecting feedback from real users, developers can gain insights into how the software performs in a variety of scenarios and adjust it accordingly to ensure a positive user experience.
# How to Conduct Live Testing
Conducting live testing requires careful planning and execution. Here are some steps to follow when conducting live testing:
- Identify your target audience: Determine who your target audience is and how they are likely to use the software. This will help you design test scenarios that are relevant and representative of real-world usage.
- Define test scenarios: Create test scenarios that simulate real-world usage and cover a range of different scenarios. This will help you identify any issues or bugs that may arise in different usage scenarios.
- Recruit beta testers: Recruit beta testers who represent your target audience and are willing to use the software and provide feedback on their experience.
- Deploy the software: Deploy the software to the beta testers and collect feedback on its performance in real-world scenarios.
- Analyze feedback: Analyze the feedback collected from the beta testers and identify any issues or areas for improvement.
- Make necessary adjustments: Make necessary adjustments to the software based on the feedback received, and conduct additional testing as needed to ensure that the changes have resolved any issues.
# Conclusion
Live testing is an important component of software testing that allows developers to collect valuable feedback from real users in real-world scenarios. By conducting live testing, developers can identify and fix issues before releasing the software to the public, increasing user satisfaction and reducing the risk of negative user experiences. WeTest Live Testing has instant access to hundreds of iOS and Android Real Devices on WeTest Cloud and it could help enterprises save millions of software and hardware costs.

tags: aws,terraform,devops,tutorial
canonical_url: https://rtfm.co.ua/en/pritunl-launching-a-vpn-in-aws-on-ec2-with-terraform/
---
I’ve already written a little about Pritunl before — [Pritunl: Running a VPN in Kubernetes](https://rtfm.co.ua/en/pritunl-running-vpn-in-kubernetes/).
Let’s return to this topic again, but this time on EC2 in AWS, without Kubernetes.
So, what we need to do is to run some kind of VPN service for the project to have access to Kubernetes APIs/Kubernetes WorkerNodes/AWS RDS/etc in private networks.
There are a lot of choice here — AWS VPN, vanilla OpenVPN, and much more.
But I’ve already used Pritunl in several projects, it has a nice interface, the basic VPN features are available in the Free version — so no problem.
### What is Pritunl?
In fact, Pritunl is a wrapper over a regular OpenVPN server. It is fully compatible, uses the same configurations, and so on.
It can integrate with AWS VPC — [https://pritunl.com/vpc](https://pritunl.com/vpc), but I don’t really want someone to automatically change routing tables.
Our network setup in AWS is very basic, and so far, we can manage everything ourselves — more control, more understanding of what can go wrong.
Plus, this integration seems to be available only in Enterprise — [Pritunl Pricing](https://www.saasworthy.com/product/pritunl/pricing).
The Pritunl has two main concepts — an _Organization_ and a _Server_:
- a Server describes the configuration for OpenVPN — ports, routers, DNS
- an Organization describes users
- an Organization connects to Server
Next, a user downloads an `.ovpn` file and connects with any VPN client. As far as I remember, even the default client on macOS worked with it without any problems.
### Pritunl and Terraform
On my previous project, we had Pritunl in Kubernetes, but I don’t really like this idea, because, in my opinion, VPN should be a separate service.
Speaking of Terraform, there’s an interesting [Pritunl Provider](https://registry.terraform.io/providers/disc/pritunl/latest/docs), but it requires an API key, which is only available in Pritunl Enterprise.
There is also a ready-made code from Terraform here — [Pritunl VPN](https://gitlab.com/amstal93/pritunl-vpn), but for me, it’s easier to create my own EC2 in my own VPC.
I also googled this ready-made module — [AWS VPN (Pritunl) Terraform Module](https://github.com/oozou/terraform-aws-pritunl-vpn), which looks like a working solution.
However, we are going to do it in a more grandfatherly way:
- there is a regular AWS VPC with several private subnets
- in a public subnet with Terraform we will launch a common EC2
- via AWS EC2 `user_data` we will install and run Pritunl
- and will manually configure users, servers, and routers for it
The network routing should be the next: all packets that go to the VPC are sent through the VPN, and the rest are sent through a regular connection, so the user can have this VPN always running on his workstation without affecting other traffic.
### Terraform: creating an AWS EC2 instance
So, first, we need to launch an EC2 instance which will run Pritunl.
For this instance, we need to have an AWS AMI, an SSH Key, a Security Group, a VPC ID, and we will create an AWS Route53 record.
### Getting an VPC ID
In my case, the VPC ID we are getting with `terraform_remote_state`, see more detailed description in the [Terraform: terraform_remote_state – getting Outputs from other state-files](https://rtfm.co.ua/en/terraform-terraform_remote_state-getting-outputs-from-other-state-files/):
```
data "terraform_remote_state" "vpc" {
backend = "s3"
config = {
bucket = "tf-state-backend-atlas-vpc"
key = "${var.environment}/atlas-vpc-${var.environment}.tfstate"
region = var.aws_region
dynamodb_table = "tf-state-lock-atlas-vpc"
}
}
```
In this `output` we have the VPC ID and the IDs of the public subnets:
```
$ terraform output
...
vpc_id = "vpc-0fbaffe234c0d81ea"
...
vpc_public_subnets_cidrs = tolist([
"10.0.0.0/20",
"10.0.16.0/20",
])
vpc_public_subnets_ids = [
"subnet-01de26778bea10395",
"subnet-0efd3937cadf669d4",
]
```
And then we use this data resource in the locals:
```
locals {
# get VPC info
vpc_out = data.terraform_remote_state.vpc.outputs
}
```
Although, you can also do it with [`data "aws_vpc"`](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/vpc).
### An EC2 SSH Key
Use the [key_pair](https://registry.terraform.io/providers/hashicorp/aws/3.9.0/docs/resources/key_pair) Terraform resource.
Create the key itself:
```
$ ssh-keygen
Generating public/private ed25519 key pair.
Enter file in which to save the key (/home/setevoy/.ssh/id_ed25519): /home/setevoy/.ssh/atlas-vpn
...
```
The public part can be stored in a repository — create a directory and copy it:
```
$ mkdir ssh
$ cp /home/setevoy/.ssh/atlas-vpn.pub ssh/
```
Add the `aws_key_pair` resource:
```
resource "aws_key_pair" "vpn_key" {
key_name = "atlas-vpn-key"
public_key = file("${path.module}/ssh/atlas-vpn.pub")
}
```
### An AWS Security Group
Find the home/work IP:
```
$ curl ifconfig.me
178. ***.***.52
```
Define a SecurityGroup — allow SSH only from this IP, and use `local.vpc_out.vpc_id` in `vpc_id`.
Add ports — 80 for Let’s Encrypt, which is used by Pritunl, 443 for access to the Pritunl’s admin page, also only from my IP, and port 10052 UPD for VPN clients:
```
resource "aws_security_group" "allow_ssh" {
name = "allow_ssh"
description = "Allow SSH inbound traffic"
vpc_id = local.vpc_out.vpc_id
ingress {
description = "SSH Arseny home"
from_port = 22
to_port = 22
protocol = "tcp"
cidr_blocks = ["178. ***.***.52/32"]
}
ingress {
description = "Pritunl Admin Arseny home"
from_port = 443
to_port = 443
protocol = "tcp"
cidr_blocks = ["178. ***.***.52/32"]
}
ingress {
description = "Pritunl Lets Encrypt"
from_port = 80
to_port = 80
protocol = "tcp"
cidr_blocks = ["0.0.0.0/0"]
}
ingress {
description = "Pritunl VPN port"
from_port = 10052
to_port = 10052
protocol = "udp"
cidr_blocks = ["0.0.0.0/0"]
}
egress {
from_port = 0
to_port = 0
protocol = "-1"
cidr_blocks = ["0.0.0.0/0"]
}
tags = {
Name = "${var.project_name}-${var.environment}-allow_ssh"
}
}
```
### An AWS AMI
Using [`data "aws_ami"`](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/ami), we will find the AWS AMI from Ubuntu.
At first, I tried to run Pritunl on Amazon Linux, but that `yum` and its repositories are a pain sometimes, but on Ubuntu it ran without any problems:
```
data "aws_ami" "ubuntu" {
most_recent = true
filter {
name = "name"
values = ["ubuntu/images/hvm-ssd/ubuntu-*-22.04-amd64-server-*"]
}
filter {
name = "virtualization-type"
values = ["hvm"]
}
owners = ["099720109477"] # Canonical's official AWS account ID for Ubuntu AMIs
}
```
But when using `data "aws_ami"`, keep in mind that when an update is released, AWS will create a new AMI, and the next time you run your Terraform code, it will pull up a new ID and will suggest to recreate the corresponding EC2.
Therefore, it may be better to just find the AMI ID manually and put it into variables. See [Find an AMI](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/finding-an-ami.html) and [Amazon EC2 AMI Locator](https://cloud-images.ubuntu.com/locator/ec2/).
### An AWS Elastic IP
To always have the same address, we’ll make it as a dedicated resource:
```
resource "aws_eip" "vpn_eip" {
domain = "vpc"
}
```
### An AWS Route53 VPN record
Let’s create a DNS record right away.
In the `variables.tf`, set the zone ID in Route53 and its name:
```
variable "route53_ops_zone" {
type = object({
name = string
id = string
})
default = {
name = "ops.example.co"
id = "Z02***OYY"
}
}
```
And in the `main.tf` describe the record itself:
```
resource "aws_route53_record" "vpn_dns" {
zone_id = var.route53_ops_zone.id
name = "vpn.${var.route53_ops_zone.name}"
type = "A"
ttl = 300
records = [aws_eip.vpn_eip.public_ip]
}
```
Now we will have an entry like “`vpn.ops.example.co IN A <EC2_EIP>`.
### The AWS EC2 and Pritunl installation
And finally, we describe EC2 itself, using the resources we created above:
- `ami` - taken from the `data.aws_ami.amazon_linux`
- `key_name` - taken from the `aws_key_pair.vpn_key.key_name`
- `vpc_security_group_ids` - from the SecurityGroup, which we create above
- `subnet_id`, where to create EC2 - take from the `local.vpc_out.vpc_public_subnets_ids`
Add the Pritunl installation here — see the documentation [[Other Providers] Ubuntu 22.04](https://docs.pritunl.com/docs/installation#other-providers-ubuntu-2204), but it’s a bit broken in places, so it might be better to do the installation manually after creating the instance.
Well, or add it to the `user_data` - at least at the time of writing, it worked with the code below.
In case of problems with EC2 `user_data` - check the log `/var/log/cloud-init.log`, and try running the script manually - it should be in a file like `/var/lib/cloud/instance/scripts/part-001`.
Keep in mind that `user_data` is called only when creating an instance - not when restarting it:
```
resource "aws_instance" "vpn" {
ami = data.aws_ami.ubuntu.id
instance_type = var.vpn_ec2_instance_type
key_name = aws_key_pair.vpn_key.key_name
vpc_security_group_ids = [aws_security_group.allow_ssh.id]
subnet_id = local.vpc_out.vpc_public_subnets_ids[0]
user_data = <<-EOF
#!/bin/bash
echo 'deb http://repo.pritunl.com/stable/apt jammy main' > /etc/apt/sources.list.d/pritunl.list
echo 'deb https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/6.0 multiverse' > /etc/apt/sources.list.d/mongodb-org-6.0.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv 7568D9BB55FF9E5287D586017AE645C0CF8E292A

ufw disable
apt -y install pritunl mongodb-org
systemctl enable mongod pritunl
systemctl start mongod pritunl
EOF
tags = {
Name = "Pritunl VPN"
}
}
```
Add the Elastic IP connection to this instance:
```
resource "aws_eip_association" "vpn_eip_assoc" {
instance_id = aws_instance.vpn.id
allocation_id = aws_eip.vpn_eip.id
}
```
### Terraform Outputs
Let’s add some `outputs` to make it easier to search for all kinds of IDs later:
```
output "vpn_ec2_id" {
value = aws_instance.vpn.id
}
output "vpn_eip" {
value = aws_eip.vpn_eip.public_ip
}
output "aws_ami_id" {
value = data.aws_ami.ubuntu.id
}
output "vpn_dns" {
value = aws_route53_record.vpn_dns.name
}
```
Run `terraform init`, `terraform plan`, and `terraform apply`:
```
...
Apply complete! Resources: 2 added, 0 changed, 0 destroyed.
Outputs:
ec2_public_ip = "3.83.69.105"
vpn_ec2_id = "i-0ea1407cb7ff8690f"
```
Check the instance:
Check SHS access to it:
```
$ ssh -i ~/.ssh/atlas-vpn ec2-user@vpn.ops.example.co
...
[ec2-user@ip-10-0-3-26 ~]$ sudo -s
[root@ip-10-0-3-26 ec2-user]#
```
Check the Pritunl itself on the server:
```
root@ip-10-0-1-25:/home/ubuntu# systemctl status pritunl
● pritunl.service - Pritunl Daemon
Loaded: loaded (/etc/systemd/system/pritunl.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2024-05-31 13:04:08 UTC; 55s ago
Main PID: 3812 (pritunl)
Tasks: 19 (limit: 2328)
Memory: 99.7M

└─4174 pritunl-web
May 31 13:04:08 ip-10-0-1-25 systemd[1]: Started Pritunl Daemon.
```
Now you can start setting it up.
### Pritunl: the initial setup
Documentation — [Configuration](https://docs.pritunl.com/docs/configuration-5).
Connect to the EC2, run `pritunl setup-key`:
```
root@ip-10-0-1-25:/home/ubuntu# pritunl setup-key
074d9be70f1944d7a77374cca09ff8dc
```
Open `vpn.ops.example.co:443`, do not pay attention to the error `ERR_CERT_AUTHORITY_INVALID` - Let's Encrypt will generate the certificate after Pritunl configuration.
Pass the `setup-key`, the MongoDB address can be left by default:
Wait for the MongoDB update:
When the login window opens, run `pritunl default-password` command on the server:
```
root@ip-10-0-1-25:/home/ubuntu# pritunl default-password
[local][2024-05-31 13:12:41,687][INFO] Getting default administrator password
Administrator default password:
username: "pritunl"
password: "1rueBHeV9LIj"
```
And log in:
Generate a new password that we will use all the time:
```
$ pwgen 12 1
iBai1Aisheat
```
And set the basic parameters of Pritunl — only login/password and addresses:
If you forget your new password, you can reset it with `pritunl reset-password`.
### The “Error getting Lets Encrypt certificate, check the logs for more information” error
If you have problems with the Let’s Encrypt certificate, check the `/var/log/pritunl.log` file:
```
root@ip-10-0-1-25:/home/ubuntu# tail -f /var/log/pritunl.log
File "/usr/lib/pritunl/usr/lib/python3.9/site-packages/pritunl/handlers/settings.py", line 1112, in settings_put
acme.update_acme_cert()
File "/usr/lib/pritunl/usr/lib/python3.9/site-packages/pritunl/acme.py", line 73, in update_acme_cert
cert = get_acme_cert(settings.app.acme_key, csr, cmdline)
File "/usr/lib/pritunl/usr/lib/python3.9/site-packages/pritunl/acme.py", line 45, in get_acme_cert
certificate = acmetiny.get_crt(
File "/usr/lib/pritunl/usr/lib/python3.9/site-packages/pritunl/acmetiny.py", line 138, in get_crt
raise ValueError("Challenge did not pass for {0}: {1}".format(domain, authorization))
ValueError: Challenge did not pass for vpn.ops.example.co: {'identifier': {'type': 'dns', 'value': 'vpn.ops.example.co'}, 'status': 'invalid', 'expires': '2024-06-07T13:32:30Z', 'challenges': [{'type': 'http-01', 'status': 'invalid', 'error': {'type': 'urn:ietf:params:acme:error:dns', 'detail': 'DNS problem: NXDOMAIN looking up A for vpn.ops.example.co - check that a DNS record exists for this domain; DNS problem: NXDOMAIN looking up AAAA for vpn.ops.example.co - check that a DNS record exists for this domain', 'status': 400}, 'url': 'https://acme-v02.api.letsencrypt.org/acme/chall-v3/357864308812/RHhMwA', 'token': 'KZLx4dUxDmow5uMvfJdwbgz5bY4HG0tTQOW2m4UvFBg', 'validated': '2024-05-31T13:32:30Z'}]}
acme_domain = "vpn.ops.example.co"
```
The domain is new — Let’s Encrypt doesn’t know about it yet.
Wait a few minutes and try again.
A successful certificate registration in the logs should look like this:
```
[INFO] Found domains: vpn.ops.example.co
[INFO] Getting directory...
[INFO] Directory found!

```
### Creating a Pritunl Organization and users
Add an organization — we’ll use it to group users, because Groups are not available in the Pritunl Free version:
Add a user:
Email and Pin are optional, not required at the moment:
### Creating a Pritunl Server and routing
See [Server configuration](https://docs.pritunl.com/docs/configuration-3).
Go to the Servers, add a new one:
In the DNS Server field, set the DNS address of our VPC.
In the Port, specify the port that was opened on AWS EC2 SecurityGroup, the UPD 10052 in this case.
The Virtual Network — the pool from which addresses will be allocated to clients. I’m using _172.*_ here because it’s easier to distinguish it from others — at home I have _192.*_, in the AWS VPC — _10.*_.
Connect the previously created Organization:
Start the server:
Set up Routes, so that only VPC requests will go through the VPN:
And remove the default route to the 0.0.0.0/0:
### Linux OpenVPN — connecting to the Pritunl server
Go to Users, click on the Download profile:
Unpack it:
```
$ tar xfpv test-user.tar
org-all_test-user_org-all-serv.ovpn
```
And connect using a common OpenVPN client:
```
$ sudo openvpn --config org-all_test-user_org-all-serv.ovpn
```
In the case of the error “**ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such device**” on Linux, try rebooting. My kernel was updated, and I haven’t rebooted for a long time.
Check the local routes:
```
$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.3.1 0.0.0.0 UG 600 0 0 wlan0
0.0.0.0 192.168.3.1 0.0.0.0 UG 1002 0 0 enp2s0f0
10.0.0.0 172.16.0.1 255.255.0.0 UG 0 0 0 tun0
172.16.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0
...
```
Everything is fine — we go to the Internet, the `0.0.0.0`, via the old route, through the home router, and to the VPC, `10.0.0.0`, via `172.16.0.1`, our VPN.
Let’s try it:
```
$ traceroute 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 60 byte packets
1 _gateway (192.168.3.1) 1.617 ms 1.550 ms 1.531 ms
...
9 one.one.one.one (1.1.1.1) 17.265 ms 17.246 ms 18.600 ms
```
Okay, through the home router.
And to some server in the AWS VPC:
```
$ traceroute 10.0.42.95
traceroute to 10.0.42.95 (10.0.42.95), 30 hops max, 60 byte packets
1 172.16.0.1 (172.16.0.1) 124.407 ms 124.410 ms 124.417 ms
...
```
Via the VPN connection.
And even SSH to instances on a private network works:
```
$ ssh -i test-to-del.pem ubuntu@10.0.45.127
...
ubuntu@ip-10-0-45-127:~$
```
Nice!
### Linux Systemd, and Pritunl/OpenVPN autostart
Let’s make sure that the connection is always running.
Create a directory:
```
$ sudo mkdir /etc/pritunl-client
```
Move the config file:
```
$ sudo mv org-all_test-user_org-all-serv.ovpn /etc/pritunl-client/work.ovpn
```
Create a simple `/etc/systemd/system/pritunl-org.service`:
```
[Unit]
Description=Pritunl Work
[Service]
Restart=always
WorkingDirectory=/etc/pritunl-client/
ExecStart=/usr/bin/openvpn --config work.ovpn
ExecStop=killall openvpn
[Install]
WantedBy=multi-user.target
```
Check it:
```
$ systemctl start pritunl-org.service
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ====
Authentication is required to start 'pritunl-org.service'.
```
And routes once again:
```
$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.3.1 0.0.0.0 UG 100 0 0 enp2s0f0
0.0.0.0 192.168.3.1 0.0.0.0 UG 600 0 0 wlan0
0.0.0.0 192.168.3.1 0.0.0.0 UG 1002 0 0 enp2s0f0
10.0.0.0 172.16.0.1 255.255.0.0 UG 0 0 0 tun0
```
Everything is there.
Add to auto start:
```
$ systemctl enable pritunl-org.service
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-unit-files ====
Authentication is required to manage system service or unit files.
Authenticating as: root
Password:
==== AUTHENTICATION COMPLETE ====
Created symlink /etc/systemd/system/multi-user.target.wants/pritunl-org.service -> /etc/systemd/system/pritunl-org.service.
```
Done.

Nada mas lejos de la verdad, si bien la fuente de la verdad absoluta siempre serán los datos provenientes de una API. La data de los endpoints por si sola no tiene significados hasta que no la estructuramos y la usamos.
Cuando definimos el estado de una aplicación, estructuramos data de modo que la UI puede mostrar información y/o ciertas acciones pueden ser permitidas o negadas.
Otro escenario es cuando queremos que cierta data persista pero solo en el navegador. ¿Porqué no todo en el server? Bueno crear/mantener un endpoint involucra un costo y hay veces que la persistencia que se busca no requiere de un servidor (ejemplo: un token de autenticación).
Bueno continuamos, normalmente la data del estado de una aplicación esta in-memory y cuando abrimos otra tab, tiene su propio stack de memoria donde la data no se comparte.
El browser tiene varios mecanismos de storage: LocalStorage, SessionStorage, Cache API, IndexedDB, etc. Cada uno tiene un propósito pero por el momento no ahondaremos en eso, me enfocaré en que estos nos ofrecen persistencia a nivel dominio, lo cual es útil para poder tener datos que sean consistentes en todas la tabs abiertas en nuestra web en un navegador y en algunos casos poder hacer sincronización de datos con el servidor cuando por alguna razón perdemos la conexión o estamos en modo "offline".
## Consideraciones
Ya vimos que tenemos varios storages para persistir datos, ¿y?. La persistencia en el browser involucra ciertas consideraciones que hay que tomar en cuenta para la estabilidad y el buen funcionamiento de nuestra web
### Persistencia temporal
La data del browser (storage) puede ser borrada ya sea por el mismo browser o por el usuario. Esta consideración nos agrega un constraint.
> En ningún momento des por hecho que va a existir data
Hay data que corresponde a operaciones sensibles, como un flujo de pagos que es preferible manejar la persistencia a nivel servidor y quizas solo persistir en el browser el resultado final porque la data podría ser borrada en cualquier momento, cosa que no pasaría en una base de datos en el servidor.
### Limites y permisos
Si bien los equipos de computo tienen cada vez mas potencia, también es cierto que la exigencia a estos equipos es mayor y los recursos son limitados. A diferencia de un servidor donde como developers tenemos el poder absoluto del sudo (chiste linuxero). En el browser podríamos tener permisos o no, tener espacio o no. Para resolver estas preguntas tenemos el [StorageManager API](https://developer.mozilla.org/en-US/docs/Web/API/StorageManager).
Esta API nos ofrece métodos como **estimate** que nos regresa una promesa que objeto con la _quota_ (espacio máximo que podemos usar), _usage_ (lo que hemos usado) y usageDetails.
Cada browser tiene sus políticas para el storage, la quota puede variar incluso la parte de permisos. También hay que mencionar que cada storage tiene también sus limitantes, esto nos deja otro constraint.
> No asumas que toda la data que intentas guardar va a persistir
Si quieres saber mas del Storage y la persistencia, te recomiendo leer este [artículo](https://web.dev/articles/persistent-storage).
El storage manager tiene 2 métodos llamados [persist](https://developer.mozilla.org/en-US/docs/Web/API/StorageManager/persist) y [persisted](https://developer.mozilla.org/en-US/docs/Web/API/StorageManager/persisted) que nos ayudan con la cuestion de permisos.
Nota: Los storage se categorizan en 2 "Best Effort" y "Persistent". Para mas detalles consulta este [artículo](https://web.dev/articles/storage-for-the-web#eviction). También te recomendamos esta referencia de [como el browser administra las quotas](https://developer.mozilla.org/en-US/docs/Web/API/Storage_API/Storage_quotas_and_eviction_criteria).
## Conclusiones
La persistencia involucra factores a tomar en cuenta como Permisos y Quotas. Y estos pueden ser determinados por las políticas de cada navegador y el dispositivo donde se ejecuta nuestra web.
¿Vale la pena saber esto? Claro, el tener conocimiento de estas APIs, sus beneficios y sus limitantes nos da herramientas para brindar una mejor experiencia a los usuarios y ellos son lo mas importante.

I cloned the Chrome devtools frontend source code and ran `npx http-server .`. Then I visited `http://127.0.0.1:8080/front_end/devtools_app.html?ws=localhost:8899`, which connects to my backend WebSocket server (`localhost:8899`). The server listens for messages from the frontend and responds using the **Chrome DevTools Protocol**. However, the console panel displays nothing. How can I activate the console so it displays messages?
This is my backend code:
```javascript
const { WebSocketServer } = require('ws');
const wss = new WebSocketServer({ port: 8899 });
wss.on('connection', function connection(ws) {
ws.on('message', function message(data) {
console.log('received: %s', data);
const message = JSON.parse(data);
if (message.method === 'Runtime.enable') {
ws.send(
JSON.stringify({

Unveiling Your Brand Identity: A Journey of Self-Discovery

published: true

---
I’m Asrul, the creator of [Resmume](https://resmume.com/). A few years ago, while listening to my wife, Gita (not her real name), talk about her experiences screening candidates, I realized something. She often reviewed stacks of resumes and mentioned that many skilled people had resumes that didn’t truly showcase their abilities. She observed that a lot of job seekers were missing opportunities because their resumes didn’t highlight their true skills.
One candidate, Yola, particularly stood out to Gita. Yola was talented, driven, and had all the right qualifications. However, Yola’s resume used a non-standard template and had a few unprofessional tones. The first tool Yola used was the most popular resume builder, offering many design options but lacking standard templates optimized for Applicant Tracking Systems (ATS). Additionally, it did not provide features to help improve writing and ensure it met industry standards. Gita saw potential in Yola but knew that many other hiring managers might overlook her because of these issues.
That’s when the idea struck me. What if there was a tool that could help people like Yola create resumes that not only looked professional but also boosted their confidence in their job search? A tool that provided standard templates, an AI writing assistant to improve grammar and professional tone, and relevant content for each specific job role.
I started sketching out ideas, delving into the world of AI, and researching professional and ATS-friendly templates. I aimed to create something that was simple, effective, and genuinely helpful. Having used several resume builders myself, I found them lacking. Most required a subscription even for occasional use, which felt unfair. I wanted to build something accessible and practical. After months of work and countless iterations, Resmume was launched.
My goal with Resmume is to make it incredibly easy for anyone to create a resume they can be proud of. Here’s how I did it:
1. Standard Templates/ATS: I provided a range of professional templates designed to be ATS (Applicant Tracking System) friendly, ensuring that resumes wouldn’t be filtered out before reaching human eyes.
2. AI Writing Assistant: Using AI, specifically GPT-4, I optimized prompts to fix grammar, enhance the tone to be more professional, and suggest powerful wording to make each bullet point measurable, focusing on achievements rather than day-to-day tasks.
3. Multiple Profiles: Based on user feedback, especially from one of my early users named Ridho, I enabled users to create multiple resume versions tailored for different roles. Ridho suggested this feature to help people apply for various positions without starting from scratch each time.
4. AI Review for Relevancy: Leveraging AI, specifically GPT-4, I optimized prompts to analyze the role and the entire resume for relevancy, ensuring each resume is customized to match specific job requirements and highlights the most relevant experiences and skills.
After a few months, Resmume received many positive reviews from users. Many of them successfully landed their dream jobs after using Resmume. One such user was Nico (not his real name). Nico faced similar issues to Yola's; he used a popular design tool that offered many non-standard template options and lacked optimization for ATS and a writing assistant to improve his resume. After using Resmume, Nico secured the job he desired.
So, if you’re staring at your resume, wondering if it’s good enough, remember you’ve got the skills and the drive. Let Resmume, the [online resume maker](https://resmume.com/), help you present your qualifications in the best possible way. Together, we can make your dream job a reality.
Thanks for reading, and here’s to your success!

1,898,535 | What are benefits of Identity and Access Management (IAM) | Benefits of Identity and Access Management (IAM) In today's digital age, organizations face... | 0 | 2024-06-24T07:31:28 | https://dev.to/blogginger/what-are-benefits-of-identity-and-access-management-iam-24ah | **Benefits of Identity and Access Management (IAM)**
In today's digital age, organizations face increasing challenges in managing user identities and controlling access to critical resources. Identity and Access Management (IAM) has emerged as a cornerstone of cybersecurity, providing a comprehensive framework to ensure that the right individuals have the appropriate access to technology resources. Here, we delve into the key benefits of IAM for organizations of all sizes.
#### 1. Enhanced Security
**Protection Against Unauthorized Access:** IAM systems provide robust mechanisms for authenticating users and granting access based on predefined policies. This minimizes the risk of unauthorized access to sensitive data and systems, safeguarding against internal and external threats.
**Reduced Risk of Data Breaches:** By enforcing strong authentication methods, such as multi-factor authentication (MFA), IAM helps in mitigating the risk of data breaches. MFA requires users to provide multiple forms of verification, making it significantly harder for attackers to gain access.
**Centralized Access Control:** IAM enables centralized management of access controls, making it easier to implement consistent security policies across the organization. This centralization simplifies the process of monitoring and managing access rights, reducing the likelihood of security gaps.
#### 2. Improved Compliance
**Regulatory Adherence:** Many industries are subject to stringent regulatory requirements regarding data protection and privacy. IAM helps organizations comply with regulations like GDPR, HIPAA, and SOX by ensuring proper access controls and maintaining detailed logs of user activities.
**Audit Trails:** IAM systems maintain comprehensive logs of user access and activity, which are crucial during audits. These logs provide a clear record of who accessed what information and when, making it easier to demonstrate compliance with regulatory standards.
**Policy Enforcement:** IAM facilitates the enforcement of security policies and ensures that users adhere to compliance requirements. Automated policy enforcement reduces human error and ensures consistent application of security measures across the organization.
#### 3. Operational Efficiency
**Streamlined User Management:** IAM automates many aspects of user lifecycle management, including onboarding, offboarding, and role changes. This automation reduces the administrative burden on IT staff and ensures that access rights are promptly updated as users join, leave, or change roles within the organization.
**Self-Service Capabilities:** [IAM solutions](https://www.authx.com/identity-and-access-management/?utm_source=devto&utm_medium=SEO&utm_campaign=blog&utm_id=K003) often include self-service portals that allow users to manage their own passwords, request access to resources, and perform other tasks without IT intervention. This reduces the workload on IT departments and improves user satisfaction by providing immediate assistance.
**Scalability:** As organizations grow, IAM systems can scale to accommodate an increasing number of users and resources. This scalability ensures that access management remains efficient and effective, even in large and complex environments.
#### 4. Cost Savings
**Reduced IT Costs:** By automating user management tasks and reducing the need for manual intervention, IAM can significantly lower IT operational costs. IT staff can focus on more strategic initiatives instead of routine access management tasks.
**Minimized Risk of Costly Breaches:** Data breaches can result in substantial financial losses due to fines, legal fees, and reputational damage. By enhancing security and reducing the risk of breaches, IAM helps organizations avoid these potentially crippling costs.
**Improved Resource Utilization:** Efficient access management ensures that users have access to the resources they need to perform their jobs effectively, without unnecessary delays. This improves overall productivity and optimizes the use of technology resources.
#### 5. Enhanced User Experience
**Single Sign-On (SSO):** IAM solutions often include [Single Sign-On](https://www.authx.com/single-sign-on/?utm_source=devto&utm_medium=SEO&utm_campaign=blog&utm_id=K003) capabilities, allowing users to access multiple applications with a single set of credentials. This simplifies the login process, reduces password fatigue, and enhances the user experience.
**Personalized Access:** IAM enables fine-grained access control, ensuring that users have access only to the resources they need. This personalization not only enhances security but also streamlines the user experience by removing unnecessary clutter.
**Quick Response to Access Requests:** With automated workflows for access requests and approvals, IAM ensures that users can quickly obtain the access they need to perform their tasks. This responsiveness supports business agility and improves user satisfaction.
### Conclusion
[Identity and Access Management](https://www.authx.com/blog/what-is-identity-and-access-management/) is a critical component of modern cybersecurity strategies, offering numerous benefits that extend beyond enhanced security. From improving compliance and operational efficiency to providing cost savings and an improved user experience, IAM is indispensable for organizations seeking to safeguard their digital assets and streamline their operations. As cyber threats continue to evolve, investing in a robust IAM solution is not just a strategic advantage but a necessity for long-term success. | blogginger | |

🛈 本文會以 x86 組合語言程式碼解說, 有關 x86 組合語言, 可參考這一篇[哈佛大學 C61 課程的課堂筆記](https://cs61.seas.harvard.edu/site/2021/Asm/#Calling-convention)。
## 沒有虛擬函式的類別
對於沒有虛擬函式的一般類別, 是最單純的, 像是以下這個[簡單的範例](https://godbolt.org/z/e7TrT3a17)：
```cpp
#include <iostream>
using namespace std;
class A {
public:
char c;
void f() {}
};
int main(void)
{
A a;
a.c = 'a';
a.f();
}
```
以下是編譯後的組合語言程式碼, 經過編譯之後, 會把 A 類別的成員函式變成一般函式, 也就是 `A::f()` 標籤處, 但是需要傳入物件位址當第一個引數, 這就是成員函式中 `this` 指位器的由來：
```nasm
A::f(): ; 類別 A 的成員函式 f
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
mov QWORD PTR [rbp-8], rdi ; 取得第一個參數 (物件位址) 放入區域變數 (this)
nop
pop rbp ; 復原 rbp
ret ; 返回
```
要注意的是, 區域變數佔用的空間是以 16 個位元組為單位配置的堆疊框 (stack frame), 不夠用的話就會再配置 16 個位元組, 依此類推。這裡因為 A 類別只有一個字元型別的資料成員, 只會佔用 1 個位元組, 所以只需要配置 16 位元組的空間, 會使用配置區塊的最高一個位元組放置這個字元資料, 物件 a 也是同樣的位址：
```nasm
main:
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
sub rsp, 16 ; 保留空間配置區域變數
mov BYTE PTR [rbp-1], 97 ; 將 'a' 放入 a.c
```
實際呼叫成員函式時也會自動加上傳入物件位址為引數的程式碼：
```nasm
lea rax, [rbp-1] ; 取得 a 物件的位址
mov rdi, rax ; 設為第一個引數
call A::f() ; 呼叫成員函式 f
mov eax, 0 ; 設定 main 的返回值為 0
leave ; 復原堆疊
ret ; 返回
```
## 加上虛擬函式
一旦類別內含有虛擬函式時, 編譯器就必須生成額外的程式碼, 例如以下這個[加上虛擬函式的範例](https://godbolt.org/z/Eo45nKcsY)：
```cpp
#include <iostream>
using namespace std;
class A {
public:
char c;
virtual void f() {}
};
int main(void)
{
A a;
a.c = 'a';
a.f();
}
```
以下是編譯器實際生成的組合語言程式碼, 之後會分段解說：
```nasm
A::f(): ; 類別 A 的成員函式 f
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
mov QWORD PTR [rbp-8], rdi ; 取得物件位址, 也就是 this
nop
pop rbp ; 復原 rbp
ret
A::A() [base object constructor]: ; 編譯器自動建立的建構函式
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
mov QWORD PTR [rbp-8], rdi ; 取得物件位址, 自動建立 this 變數
; 將 vtable 中用來儲存成員函式位址的區塊位址放入 edx
mov edx, OFFSET FLAT:vtable for A+16
mov rax, QWORD PTR [rbp-8] ; 將 this 放入 rax
; 將 vtable 中用來儲存成員函式位址的區塊位址儲存到新配置物件內
mov QWORD PTR [rax], rdx
nop
pop rbp ; 復原 rbp
ret
main:
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
sub rsp, 16 ; 配置 a 物件的空間
lea rax, [rbp-16] ; 取得 a 物件位址
mov rdi, rax ; 放入成為第一個引數
call A::A() [complete object constructor] ; 呼叫建構函式
mov BYTE PTR [rbp-8], 97 ; 將 'a' 放入 a 的成員 c 中
lea rax, [rbp-16] ; 取得 a 物件位址
mov rdi, rax ; 放入成為第一個引數
call A::f() ; 呼叫 A 類別的 f 成員函式
mov eax, 0 ; 放入 0 當成 main 的傳回值
leave ; 復原堆疊
ret ; 返回
vtable for A: ; A 類別的 vtable
.quad 0 ; 保留欄位
.quad typeinfo for A ; A 類別型別資訊的位址
.quad A::f() ; 成員函式 f 的位址
typeinfo for A:
.quad vtable for __cxxabiv1::__class_type_info+16
.quad typeinfo name for A
typeinfo name for A:
.string "1A"
```
只要類別中存在虛擬函式, 編譯器就會幫該類別建立一個虛擬函式表 (vtable), `vtable for A:` 標籤處就是類別 A 的虛擬表格：
```nasm
vtable for A: ; A 類別的 vtable
.quad 0 ; 保留欄位
.quad typeinfo for A ; A 類別型別資訊的位址
.quad A::f() ; 成員函式 f 的位址
typeinfo for A:
.quad vtable for __cxxabiv1::__class_type_info+16
.quad typeinfo name for A
typeinfo name for A:
.string "1A"
```
表格內是用來儲存位址的一個個欄位, 包含了開頭固定的 0 欄位、執行時期型別資訊 (RTTI, Run-Time Type Information) 的位址 (typeinfo for A 標籤處) 以及個別虛擬函式的位址。整體結構如下圖所示：
```
A 類別的虛擬函式表
+-------
| 0 A 類別的 RTTI
+------- +-------------
| RTTI ------------> | 虛擬函式表位址
+------- +-------------
| f ------+ | 型別名稱位址
+------- | +-------------
|
+-----> A::f()
```
為了搭配上述虛擬函式表運作, 編譯器還會自動幫該類別生成建構函式, 也就是 `A::A() [base object constructor]` 標籤處：
```nasm
A::A() [base object constructor]: ; 編譯器自動建立的建構函式
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
mov QWORD PTR [rbp-8], rdi ; 取得物件位址, 自動建立 this 變數
; 將 vtable 中用來儲存成員函式位址的區塊位址放入 edx
mov edx, OFFSET FLAT:vtable for A+16
mov rax, QWORD PTR [rbp-8] ; 將 this 放入 rax
; 將 vtable 中用來儲存成員函式位址的區塊位址儲存到新配置物件內
mov QWORD PTR [rax], rdx
nop
pop rbp ; 復原 rbp
ret
```
這個建構函式會自動幫新建立的物件在所有資料成員前面安插一個指向虛擬函式表的指位器。不過要注意的是, 安插在物件中的指位器並不是指向虛擬函式表的開頭, 而是直接指到虛擬函式表中第一個紀錄虛擬函式位址的欄位。**之後我們提到虛擬函式表的位址時, 指的都是這個位址, 而不是真正虛擬函式表開頭的位址**。
在 `main` 中, 一開始一樣是配置區域變數的空間, 現在的 `a` 物件除了一個字元型別的資料成員外, 還需要放置虛擬函式表的位址, 共需要 1+8 個位元組, 所以仍然只需要配置 16 個位元組的堆疊框就夠用：
```nasm
main:
push rbp ; 儲存 rbp
mov rbp, rsp ; 取得堆疊頂端
sub rsp, 16 ; 配置 a 物件的空間
lea rax, [rbp-16] ; 取得 a 物件位址
```
接著, 就可以傳入新配置物件的位址呼叫編譯器自動產生的建構函式：
```nasm
mov rdi, rax ; 放入成為第一個引數
call A::A() [complete object constructor] ; 呼叫建構函式
```
雖然和前一個範例一樣保留了 16 個位元組做為區域變數空間, 不過因為儲存虛擬函式表位置的指位器需要對齊 8 的位址, 不能把所有的資料都往高位址靠, 所以低位址開始的 8 個位元組就是放置虛擬函式表的位址, 資料成員 `c` 則是放在下一個 8 位元組的低位址處：
```nasm
mov BYTE PTR [rbp-8], 97 ; 將 'a' 放入 a 的成員 c 中
```
建立 a 物件後的整體結構如下圖：
```
a 物件
+--------------- A 類別的虛擬函式表
| vtable pointer ---+ +-------
+--------------- | | 0 A 類別的 RTTI
| c = 'a' | +------- +-------------
|--------------- | | RTTI ------------> | 虛擬函式表位址
| +------- +-------------
+-----> | f ------+ | 型別名稱位址
+------- | +-------------
|
+-----> A::f()
```
本例雖然有虛擬函式, 不過主程式中並沒有透過指向物件的指位器或是參照呼叫成員函式, 所以實際上呼叫成員函式的部分和前一個範例是一樣的, 因為編譯器在編譯時就可以確定該呼叫哪一個函式, 不會有問題：
```nasm
lea rax, [rbp-16] ; 取得 a 物件位址
mov rdi, rax ; 放入成為第一個引數
call A::f() ; 呼叫 A 類別的 f 成員函式
mov eax, 0 ; 放入 0 當成 main 的傳回值
leave ; 復原堆疊
ret ; 返回
```
## 透過指位器呼叫成員函式
目前還看不出來虛擬函式表的用處, 不過只要透過指向物件的指位器或是參照呼叫成員函式時, 編譯器就無法在編譯時確認實際指向的是哪一種類別的物件, 必須藉助虛擬函式表間接呼叫成員函式, 請看以下[改用指位器呼叫成員函式](https://godbolt.org/z/cnoj7h6Gc)的範例：
```cpp
#include <iostream>
using namespace std;
class A {
public:
char c;
virtual void f() {}
};
int main(void)
{
A a;
A *pa = &a;
a.c = 'a';
pa->f();
}
```
以下省略組合語言與前面範例相同的部分, 只看不一樣的地方, 就是 `main` 函式：
```nasm
main:
push rbp
mov rbp, rsp
sub rsp, 32
lea rax, [rbp-32]
mov rdi, rax
call A::A() [complete object constructor]
```
首先因為除了 `a` 物件, 還有 `pa` 指位器, 所以單單配置 16 位元組的區域變數空間並不足夠, 所以這裡改成配置 32 位元組的空間。隨區域變數空間的變化, 也要調整取得 `a` 物件位址的程式碼, 以下是設定 `a` 物件中資料成員 `c` 的部分：
```nasm
lea rax, [rbp-32] ; 取得 a 物件位址
mov QWORD PTR [rbp-8], rax ; 放入 pa 指位器
mov BYTE PTR [rbp-24], 97
```
你可以看到現在呼叫成員函式的組合語言程式碼跟剛剛明顯不同, 複雜得多, 但其實就是到虛擬函式表中查成員函式的位址後再呼叫：
```nasm
mov rax, QWORD PTR [rbp-8] ; 從 pa 指位器取得 a 物件位址
mov rax, QWORD PTR [rax] ; 從 a 物件位址取得 vtable 位址
mov rdx, QWORD PTR [rax] ; 取得 f 成員函式位址
mov rax, QWORD PTR [rbp-8] ; 從 pa 指位器取得 a 物件位址
mov rdi, rax ; 設定為第一個引數
call rdx ; 呼叫 f 成員函式
mov eax, 0
leave
ret
vtable for A:
.quad 0
.quad typeinfo for A
.quad A::f()
...(略)
```
要注意的是虛擬函式表中是依照定義類別時的虛擬函式順序排列, 本例只有一個虛擬函式, 實際查表的步驟就是：
1. 透過指位器取得 a 的位址
2. 取得 a 物件內虛擬函式表的位址
3. 從虛擬函式表中取得成員函式 f 的位址
4. 呼叫成員函式 f, 並傳入指位器指向的位址
## 加入多個虛擬函式
剛剛的範例只有一個虛擬函式, 所以還看不出來關鍵的差異, 這裡幫類別[再加入一個虛擬函式](https://godbolt.org/z/c5K7cs17E)：
```cpp
#include <iostream>
using namespace std;
class A {
public:
char c;
virtual void f() {}
virtual void f2() {}
};
int main(void)
{
A a;
A *pa = &a;
a.c = 'a';
pa->f2();
}
```
以下只列出組合語言碼中變化的部分, 首先, 虛擬函式表現在多了一欄, 記錄成員函式 `f2` 的位址：
```nasm
vtable for A:
.quad 0
.quad typeinfo for A
.quad A::f()
.quad A::f2()
```
由於主程式中改成呼叫成員函式 `f2`, 所以組合語言碼也要跟著變, 取得虛擬函式表位址再加 8 的位址的內容, 才是 `f2` 的位址：
```nasm
mov rax, QWORD PTR [rbp-8] ; 取得指位器指向的位址
mov rax, QWORD PTR [rax] ; 取得虛擬函式表的位址
add rax, 8 ; 取得指向下一欄 (也就是 f2) 的位址
mov rdx, QWORD PTR [rax] ; 取得 f2 的位址
mov rax, QWORD PTR [rbp-8] ; 取得指位器指向的位址
mov rdi, rax ; 傳入當引數
call rdx ; 呼叫函式
```
現在應該可以明確的看到呼叫虛擬函式就變成查表後再呼叫了。
## 加入子類別
虛擬函式要發揮作用必需要有子類別, 請看以下這個[加上子類別的範例](https://godbolt.org/z/5jKca1cYs)：
```cpp
#include <iostream>
using namespace std;
class A {
public:
char c;
virtual void f() {}
virtual void f2() {}
};
class B:public A {
};
int main(void)
{
B b;
B *pb = &b;
pb->c = 'a';
pb->f2();
}
```
首先可以看到由於 `B` 繼承 `A`, 所以也是具有虛擬函式的類別, 生成的組合語言程式碼就會有兩個類別的虛擬函式表：
```nasm
vtable for B:
.quad 0
.quad typeinfo for B
.quad A::f()
.quad A::f2()
vtable for A:
.quad 0
.quad typeinfo for A
.quad A::f()
.quad A::f2()
```
雖然 `B` 繼承 `A`, 不過 `B` 的虛擬函式表並不是直接放一個指向 `A` 的虛擬函式表的位址, 而是重複一遍 `A` 中的所有虛擬函式, 這樣在查找虛擬函式位址時, 就不需要再一層層查找父類別的虛擬函式表了。
同時也可以看到編譯器也會自動建立 `B` 類別的建構函式：
```nasm
B::B() [base object constructor]:
push rbp
mov rbp, rsp
sub rsp, 16 ; 配置區域變數空間
mov QWORD PTR [rbp-8], rdi ; 設定 this 指向物件
mov rax, QWORD PTR [rbp-8] ; 取得 this
mov rdi, rax ; 設為引數
call A::A() [base object constructor] ; 呼叫父類別的建構函式
mov edx, OFFSET FLAT:vtable for B+16 ; 取得 B 類別的虛擬函式表位址
mov rax, QWORD PTR [rbp-8] ; 取得 this
mov QWORD PTR [rax], rdx ; 放入物件開頭
nop
leave
ret
```
內容與 `A` 的基本上是一樣的, 只是它會幫你呼叫父類別 `A` 的建構函式, 然後再將 `B` 類別的虛擬函式表位址覆蓋上去。
在 `main` 中我們特意改成使用指位器設定資料成員 `c`, 觀察組合語言程式碼：
```nasm
main:
push rbp
mov rbp, rsp
sub rsp, 32 ; 配置區域變數空間
lea rax, [rbp-32] ; 取得 b 位址
mov rdi, rax ; 設為引數
call B::B() [complete object constructor] ; 呼叫 B 建構函式
lea rax, [rbp-32] ; 取得 b 位址
mov QWORD PTR [rbp-8], rax ; 放入 pb 中
mov rax, QWORD PTR [rbp-8] ; 取得 pb 指向位址
mov BYTE PTR [rax+8], 97 ; 把 'a' 放入資料成員 c
mov rax, QWORD PTR [rbp-8] ; 取得 pb 指向位址
mov rax, QWORD PTR [rax] ; 取得虛擬函式表位址
add rax, 8 ; 取得儲存 f2 的位址
mov rdx, QWORD PTR [rax] ; 取得 f2 位址
mov rax, QWORD PTR [rbp-8] ; 取得 pb 指向的位址
mov rdi, rax ; 設為引數
call rdx ; 呼叫 f2
mov eax, 0
leave
ret
```
你可以看到因為是透過查虛擬函式表間接呼叫成員函式的關係, 所以會根據指位器實際指向的物件, 找到正確的虛擬函式表, 因而呼叫個別物件所記錄的虛擬函式。
## 子類別覆寫 (override) 虛擬函式
雖然目前已經很清楚虛擬函式表的作用, 不過我們還可以進一步在子類別中[覆寫父類別的虛擬函式]()：
```cpp
#include <iostream>
using namespace std;
class A {
public:
char c;
virtual void f() {}
virtual void f2() {}
};
class B:public A {
virtual void f3() {}
virtual void f1() {}
};
int main(void)
{
B b;
B *pb = &b;
pb->c = 'a';
pb->f2();
}
```
這裡我們除了在 `B` 中覆寫 `f2` 以外, 還增加了 `f3` 虛擬函式。首先來看一下虛擬函式表：
```nasm
vtable for B:
.quad 0
.quad typeinfo for B
.quad B::f()
.quad A::f2()
.quad B::f3()
vtable for A:
.quad 0
.quad typeinfo for A
.quad A::f()
.quad A::f2()
```
`B` 中的虛擬函式表還是會先把 `A` 中原本的虛擬函式列出來, 然後才是 `B` 中新增的 `f3`。要注意的是, 因為 `B` 中覆寫了 `f` 函式, 所以 `B` 的虛擬函式表記錄的是 `B::f()`, 而 `A` 的虛擬函式表記錄的是 `A::f()`, 兩個類別的同名虛擬函式指向個別版本的函式了。
由於 `B` 的虛擬函式表會根據是否覆寫父類別的虛擬函式而更改內容, 所以透過指位器或是參照呼叫成員函式時, 就可以依據虛擬函式表找到正確的函式。
其餘的部分都跟上一個範例一模一樣, 就不再贅述。
## 使用指向成員函式的指位器
C++ 有提供透過指向成員函式的指位器呼叫成員函式的方法, 例如：
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f()
{
cout << "A::f()" << endl;
}
};
int main(void)
{
A a;
void (A::*pf)() = &A::f;
cout << (void *)&A::f << endl;
(a.*pf)();
return 0;
}
```
請特別留意指向成員函式的指位器的宣告方式, 一定要冠上類別名稱, 透過這種指位器執行成員函式時, 也要標明物件。執行結果如下：
```
0x4011e6
A::f()
```
你也可以透過指向物件的指位器進行同樣的操作, 例如：
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f()
{
cout << "A::f()" << endl;
}
};
int main(void)
{
A a;
A *pa = &a;
void (A::*pf)() = &A::f;
cout << (void *)&A::f << endl;
(pa->*pf)();
return 0;
}
```
利用這種語法, 我們也可以模擬透過虛擬函式表取得成員函式位址的操作：
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f()
{
cout << "A::f()" << endl;
}
};
int main(void)
{
A a;
void (A::*pf)() = &A::f;
cout << (void *)&A::f << endl;
(a.*pf)();
void (A::*pmf)() = **((void (A::***)())&a);
cout << (void *)pmf << endl;
(a.*pmf)();
return 0;
}
```
首先把 `a` 的位址轉型成指向 A 類別成員函式的三層指位器, 經過兩層取值運算從物件中取得虛擬函式表的位址、再從虛擬函式表中取得虛擬函式的位址, 放入 `pmf` 中, 即可使用指向成員函式指位器的形式呼叫成員函式。執行結果如下：
```
0x40128c
A::f()
0x40128c
0x1
A::f()
```
從顯示的位址也可以確認我們間接從虛擬函式表取得的成員函式位址是正確的。如果想要呼叫第二個開始的虛擬函式, 就必須用點小技巧：
```cpp
#include <iostream>
using namespace std;
class A
{
public:
virtual void f()
{
cout << "A::f()" << endl;
}
virtual void g()
{
cout << "A::g()" << endl;
}
};
int main(void)
{
A a;
void (A::*pf)() = &A::g;
// cout << sizeof(pf) << endl;
// 會顯示 16
cout << (void *)(&A::g) << endl;
(a.*pf)();
cout << sizeof(void (A::*)()) << endl;
void (A::***pmf0)() = ((void (A::***)())&a);
void (A::**pmf1)() = *pmf0;
// WRONG: pmf2 = pmf1 + 1
// 這會讓位址加 16, 而不是 8
// 底下耍點小技巧
void (A::**pmf2)() = (void (A::**)())((char **)pmf1 + 1);
void (A::*pmf)() = *pmf2;
cout << (void *)pmf << endl;
(a.*pmf)();
return 0;
}
```
這裡要特別注意的是, 指向成員函式的指位器大小是 16 個位元組, 但實際在虛擬函式表中每個指向函式的指位器是 8 位元組, 如果拿 `pmf1 + 1` 會得到 `pmf1` 位址加 16 的錯誤位址, 所以這裡我們耍點技巧, 先轉成指向字元的兩層指位器, 再透過轉型後的指位器做加法, 就會以加減單位是 8 位元組來計算, 得到指向第二個虛擬函式位址的指位器。執行結果如下：
```
0x4012ca
A::g()
16
0x4012ca
A::g()
```
從顯示的位址也可以確認我們自己從虛擬函式表中取得的位址是正確的。
## 結語
利用同樣的方式, 你還可以繼續觀察多重繼承的結果。根據以上的觀察, 可以看到：
1. 如果沒有定義虛擬函式, 物件的結構就只是單純的資料, 成員函式除了自動加上一個傳入物件位址的參數外, 跟一般函式沒有什麼差別。
2. 一旦定義虛擬函式, 編譯器就會幫類別建立虛擬函式表, 並且在建立物件時自動增加一個欄位記錄虛擬函式表位址。
3. 只要是透過指位器或是參照呼叫成員函式, 就會到虛擬函式表中查表間接呼叫成員函式。
4. 沒有透過指位器或是參照呼叫成員函式時, 就不會去查表, 即使呼叫的是虛擬函式也一樣。
5. 個別類別的虛擬函式表彼此獨立, 沒有關聯。
6. 由於編譯器是根據定義類別時虛擬函式的排列順序去虛擬函式表中查找位址, 如果要使用現有編譯好的目的檔, 就要小心不要修改原始檔中的虛擬函式順序與數目, 否則既有目的黨中查找虛擬函式位址的程式碼就會出錯。
所有的繼承關係、虛擬函式都是編譯器在編譯時就會處理, 並建立個別的資料區塊, 實際程式執行時, 就只是查表找到成員函式位址, 呼叫找到的函式而已。
