- This is the third blog of my series where I am writing how to write code for an industry-grade project so that you can manage and scale the project. In this blog, we will learn how to create an API endpoint. We will see how to create an interface, mongoose model, route, controller, and service file and validate with zod.
- The first two blogs of the series were about "How to set up eslint and prettier in an express and typescript project" and "Folder structure in an industry-standard project". You can check them in the following link.
https://dev.to/md_enayeturrahman_2560e3/how-to-set-up-eslint-and-prettier-1nk6
https://dev.to/md_enayeturrahman_2560e3/folder-structure-in-an-industry-standard-project-271b
- Today's code will be written on top of them.
- Let's understand the main files and what are we going to do. The routes we will create will be for the user. We will have a user.interface.ts file that will hold the code for the interface. Then we will have user.model.ts file that will contain the mongoose schema and model for the user. Then we will have user.validation.ts file. Here we will validate the data received from the front end using zod. After that, we will have user.route.ts file that will contain code related to the route. Then comes user.controller.ts file which will contain a function to handle route logic and at last user.service.ts file which will contain the business logic of the controller code.
- In order to benefit from the blog you have to go through all the code. I will write an explanation of the code in the comment beside the code.
### Folder structure
- At the beginning let's see the folder structure related to user Route.
```javascript

│ └── server.js
```
- Above are the files and folders necessary for the creation of the user route. For full file and folder structure please refer to the second blog of this series.
### User interface
- In our project, we have defined a user type in TypeScript named TUser. Although the file is named "interface," we are using a type declaration instead of an interface. Here's the definition:
```javascript
export type TUser = {
id: string;
password: string;
needsPasswordChange: boolean;
role: 'admin' | 'student' | 'faculty';
status: 'in-progress' | 'blocked';
isDeleted: boolean;
};
```
- Naming Convention: The type is named TUser, with the "T" prefix indicating it is a type. This is a convention to help differentiate types from other constructs in the code.
- **Properties:**
- **id:** A string that uniquely identifies the user.
- **password:** The user's password, is stored as a string.
- **needsPasswordChange:** A boolean indicating whether the user is required to change their password.
- **role:** An enum-like property that specifies the user's role. In our app, there are three types of users: 'admin', 'student', and 'faculty'.
- **status:** An enum-like property representing the user's current status, with possible values: 'in-progress' or 'blocked'. If a user's status is 'blocked', they cannot log in regardless of their role (admin, student, faculty). Authentication checks are performed on the user collection, so changing a user's status to 'blocked' here will prevent them from logging in, simplifying user management and maintenance.
- **isDeleted:** A boolean that indicates whether the user has been deleted. This field is stored in the real database. No document is ever truly deleted from the database; instead, its "**isDeleted**" status is changed to "**true**". If "**isDeleted**" is "**false**", the user object will be sent to the front-end during a get request. If "**isDeleted**" is "**true**", the user object, although present in the database, will not be sent to the front-end during a get request.
### User Model
- The "user.model.ts" file defines the Mongoose schema for the user, including two hooks: pre-save and post-save.
```javascript
import bcrypt from 'bcrypt';
import { Schema, model } from 'mongoose';
import config from '../../config';
import { TUser } from './user.interface';
const userSchema = new Schema<TUser>(
{
id: {
type: String,
required: true,
},
password: {
type: String,
required: true,
},
needsPasswordChange: {
type: Boolean,
default: true,
},
role: {
type: String,
enum: ['student', 'faculty', 'admin'],
},
status: {
type: String,
enum: ['in-progress', 'blocked'],
default: 'in-progress',
},
isDeleted: {
type: Boolean,
default: false,
},
},
{
timestamps: true,
},
);
userSchema.pre('save', async function (next) {
const user = this;
// hashing password and save into DB
user.password = await bcrypt.hash(
user.password,
Number(config.bcrypt_salt_rounds),
);
next();
});
// set '' after saving password
userSchema.post('save', function (doc, next) {
doc.password = '';
next();
});
export const User = model<TUser>('User', userSchema);
```
- **Imports:** I imported "bcrypt" to hash the password before saving it to the database. The "Schema" and "model" are imported from Mongoose. The "config" is imported from the index file inside the config folder, which holds the .env file variables (for details, see my first blog). The "TUser" type is imported from the interface file. It is passed to the schema to ensure that any deviations from the defined type during schema creation will trigger a warning.
- **Schema Definition:** The schema is defined using the **"Schema"** constructor from Mongoose, with **"TUser"** passed as a generic type to ensure type safety.
- **Fields:**
-**id:** A string that uniquely identifies the user. This field is required.
- **password:** The user's password, is stored as a string. This field is required.
- **needsPasswordChange:** A boolean indicating whether the user needs to change their password. It defaults to true.
- **role:** A string that specifies the user's role. It can be 'student', 'faculty', or 'admin'.
- **status:** A string representing the user's current status. It can be 'in-progress' or 'blocked', with a default value of 'in-progress'.
- **isDeleted:** A boolean indicating whether the user has been deleted. It defaults to false.
- **Options:**
- **timestamps:** When set to true, Mongoose will automatically add "**createdAt**" and "**updatedAt**" fields to the schema.
- **Explanation of the Pre-Save Hook:** The** pre('save')** hook in Mongoose is a middleware function that runs before a document is saved to the database. This pre-save hook ensures that the user's password is always hashed before being stored in the database, enhancing security by never storing plain-text passwords. Here's a breakdown of how it works in the **userSchema:**
- **Pre-Save Hook:** The pre('save') function is a middleware that is executed before the save operation.
- **Context Binding:** const user = this;: The this keyword refers to the document being saved. This line assigns this to the user for clarity and to avoid ESLint warnings.
- **Password Hashing:** user.password = await bcrypt.hash(user.password, Number(config.bcrypt_salt_rounds));: This line hashes the user's password using bcrypt before saving it to the database. The config.bcrypt_salt_rounds specifies the number of salt rounds used by bcrypt to generate the hash, enhancing password security.
- **Calling next():** The next function is called to proceed with the save operation. Without calling next(), the save operation would be halted.
- **Explanation of the Post-Save Hook:** The post('save') hook in Mongoose is a middleware function that runs after a document has been saved to the database. Here's a breakdown of how it works in the userSchema:
- **Post-Save Hook:** The **post('save')** function is a middleware that is executed after the save operation.
- ** Setting Password to Empty String:** After saving a user document to the database, it's common practice to send the user data to the front-end as a response. However, for security reasons, we should avoid transmitting hashed passwords to the front-end. Despite being securely stored in the database, hashed passwords should remain confidential. Therefore, this hook ensures that the password field is set to an empty string before sending the user document to the front-end. By doing so, we prevent the transmission of sensitive information and uphold the security of our application.
- **Calling next():** The next function is called to proceed after executing the hook. Without calling next(), the middleware chain would not continue.
- **Exporting user model:** This line exports the Mongoose model named User, which is created using the model function provided by Mongoose. The model is defined based on the TUser type and the userSchema schema. This allows us to interact with the User collection in the database using methods provided by Mongoose, such as find, findOne, create, update, and delete.
### Validation using zod
- The user.validation.ts is dedicated to validating the password field only, employing a simple validation approach. This is a simple validation. I will write another blog that will detail various types of zod validation.
```javascript
import { z } from 'zod';
const userValidationSchema = z.object({
pasword: z
.string({
invalid_type_error: 'Password must be string',
})
.max(20, { message: 'Password can not be more than 20 characters' })
.optional(),
});
export const UserValidation = {
userValidationSchema,
};
```
- We import the z object from the Zod library.
- We define a validation schema for user data using Zod's object method.
- Within the schema, we define validation rules for the password field:
- We specify that the password must be a string and provide a custom error message if the value is not a string.
- We set a maximum length of 20 characters for the password and provide a custom error message if the length exceeds this limit.
- The user will be created by the admin. At the time of user creation admin can send a password. If the admin does not send the password then the default password will be applied at the backend. That is why We mark the password field as optional.
- Finally, we export the user validation schema as UserValidation.
- Now the question comes that in the User model, we can see there are several properties of the user (id, password, needsPasswordChange, role, status, and isDeleted) but why we are validating the password field only?
- The id property will be unique and generated at the backend using auto-increment method. So it need not come from front-end. So doesn't require validation.
- The default value for needsPasswordChange, status and isDeleted fields are set in the type within the user.interface.ts file. So it need not come from front-end. So doesn't require validation.
- The role will be set from the endpoint. So it also does not need to come from front-end. So doesn't require validation.
- So the only field that may need to come from front-end is the password. That is why we are only validating it even though the user object has other fields.
### Constant file
- In our application, users can have one of three roles: student, faculty, or admin. To maintain a cleaner codebase and ensure consistency, we have created a separate file named "user.constant.ts" to hold these user roles as constants. Here's how it looks:
```javascript
export const USER_ROLE = {
student: 'student',
faculty: 'faculty',
admin: 'admin',
} as const;
```
- These constants can then be imported and used in other files, such as "user.route.ts", making our code more organized and easier to maintain.
### Route file
- Our route file holds routes, connection with the controller, and application of middleware for verifying the admin privileges.
```javascript
import express from 'express';
import auth from '../../middlewares/auth';
import validateRequest from '../../middlewares/validateRequest';
import { createAdminValidationSchema } from '../Admin/admin.validation';
import { createFacultyValidationSchema } from '../Faculty/faculty.validation';
import { createStudentValidationSchema } from './../student/student.validation';
import { USER_ROLE } from './user.constant';
import { UserControllers } from './user.controller';
const router = express.Router();
// Route for creating a student
router.post(
'/create-student',
auth(USER_ROLE.admin), // Middleware to verify admin privileges
validateRequest(createStudentValidationSchema), // Middleware for validating request
UserControllers.createStudent, // Controller function for handling the request
);
// Route for creating a faculty member
router.post(
'/create-faculty',
auth(USER_ROLE.admin), // Middleware to verify admin privileges
validateRequest(createFacultyValidationSchema), // Middleware for validating request
UserControllers.createFaculty, // Controller function for handling the request
);
// Route for creating an admin user
router.post(
'/create-admin',
validateRequest(createAdminValidationSchema), // Middleware for validating request
UserControllers.createAdmin, // Controller function for handling the request
);
export const UserRoutes = router;
```
- We define routes for creating students, faculty members, and admin users.
- Middleware functions are applied to ensure that only admin users can access the routes for creating students and faculty members.
- Request validation middleware is applied to validate the request body before passing it to the controller functions.
- Finally, the respective controller functions are invoked to handle the requests and perform the necessary actions.
### Controller file
- Below, I'll demonstrate two controller files. The first one utilizes a try-catch block for error handling, while the second one employs reusable code for error handling using a custom catchAsync function. I will write a separate blog for this reusable code to try catch later. In this blog let's focus on the logic other than the try-catch blocks:
```javascript
import httpStatus from 'http-status';
import { NextFunction, Request, Response } from 'express';
import sendResponse from '../../utils/sendResponse';
import { UserServices } from './user.service';
const createStudent = async (
req: Request,
res: Response,
next: NextFunction,
) => {
try {
const { password, student: studentData } = req.body;
const result = await UserServices.createStudentIntoDB(
password,
studentData,
);
sendResponse(res, {
statusCode: httpStatus.OK,
success: true,
message: 'Student is created succesfully',
data: result,
});
} catch (err) {
next(err);
}
};
export const UserControllers = {
createStudent,
};
```
- **httpStatus:** This package helps send status codes with responses by typing the response type.
- **createStudent Function:**
- Takes three parameters: req, res, and next.
- Destructures password and studentData from req.body.
- Calls createStudentIntoDB with the password and student data.
- Uses sendResponse to send the response to the frontend.
- In the catch block, it calls next with the error.
```javascript
import httpStatus from 'http-status';
import catchAsync from '../../utils/catchAsync';
import sendResponse from '../../utils/sendResponse';
import { UserServices } from './user.service';
const createStudent = catchAsync(async (req, res) => {
const { password, student: studentData } = req.body;
const result = await UserServices.createStudentIntoDB(password, studentData);
sendResponse(res, {
statusCode: httpStatus.OK,
success: true,
message: 'Student is created succesfully',
data: result,
});
});
const createFaculty = catchAsync(async (req, res) => {
const { password, faculty: facultyData } = req.body;
const result = await UserServices.createFacultyIntoDB(password, facultyData);
sendResponse(res, {
statusCode: httpStatus.OK,
success: true,
message: 'Faculty is created succesfully',
data: result,
});
});
const createAdmin = catchAsync(async (req, res) => {
const { password, admin: adminData } = req.body;
const result = await UserServices.createAdminIntoDB(password, adminData);
sendResponse(res, {
statusCode: httpStatus.OK,
success: true,
message: 'Admin is created succesfully',
data: result,
});
});
export const UserControllers = {
createStudent,
createFaculty,
createAdmin,
};
```
- The purpose of this code is similar to the previous one but with a different approach.
- **catchAsync:** A custom function to handle errors, eliminating the need for repetitive try-catch blocks.
- createStudent, createFaculty, createAdmin Functions:
- Destructure data from req.body.
- Call the respective service functions to create users.
- Use sendResponse to send the response to the frontend.
- This approach removes the need for try-catch blocks and the next function for error handling, making the code cleaner and more reusable.
- These examples demonstrate how to structure controller functions for user creation while maintaining clean and manageable error handling. In a later blog, we will delve into creating a custom sendResponse function and managing errors using the next function
### Service file
- Below is the explanation of the user.service.ts file, which contains functions to create different types of users (students, faculty, and admins) in the database. Each function uses MongoDB transactions to ensure data consistency.
```javascript
import httpStatus from 'http-status';
import mongoose from 'mongoose';
import config from '../../config';
import AppError from '../../errors/AppError';
import { TAdmin } from '../Admin/admin.interface';
import { Admin } from '../Admin/admin.model';
import { TFaculty } from '../Faculty/faculty.interface';
import { Faculty } from '../Faculty/faculty.model';
import { AcademicDepartment } from '../academicDepartment/academicDepartment.model';
import { TStudent } from '../student/student.interface';
import { Student } from '../student/student.model';
import { AcademicSemester } from './../academicSemester/academicSemester.model';
import { TUser } from './user.interface';
import { User } from './user.model';
import {
generateAdminId,
generateFacultyId,
generateStudentId,
} from './user.utils';
const createStudentIntoDB = async (password: string, payload: TStudent) => {
// create a user object
const userData: Partial<TUser> = {};
//if password is not given , use deafult password
userData.password = password || (config.default_password as string);
//set student role
userData.role = 'student';
// find academic semester info
const admissionSemester = await AcademicSemester.findById(
payload.admissionSemester,
);
if (!admissionSemester) {
throw new AppError(400, 'Admission semester not found');
}
const session = await mongoose.startSession();
try {
session.startTransaction();
//set generated id
userData.id = await generateStudentId(admissionSemester);
// create a user (transaction-1)
const newUser = await User.create([userData], { session }); // array
//create a student
if (!newUser.length) {
throw new AppError(httpStatus.BAD_REQUEST, 'Failed to create user');
}
// set id , _id as user
payload.id = newUser[0].id;
payload.user = newUser[0]._id; //reference _id
// create a student (transaction-2)
const newStudent = await Student.create([payload], { session });
if (!newStudent.length) {
throw new AppError(httpStatus.BAD_REQUEST, 'Failed to create student');
}
await session.commitTransaction();
await session.endSession();
return newStudent;
} catch (err: any) {
await session.abortTransaction();
await session.endSession();
throw new Error(err);
}
};
const createFacultyIntoDB = async (password: string, payload: TFaculty) => {
// create a user object
const userData: Partial<TUser> = {};
//if password is not given , use deafult password
userData.password = password || (config.default_password as string);
//set student role
userData.role = 'faculty';
// find academic department info
const academicDepartment = await AcademicDepartment.findById(
payload.academicDepartment,
);
if (!academicDepartment) {
throw new AppError(400, 'Academic department not found');
}
const session = await mongoose.startSession();
try {
session.startTransaction();
//set generated id
userData.id = await generateFacultyId();
// create a user (transaction-1)
const newUser = await User.create([userData], { session }); // array
//create a faculty
if (!newUser.length) {
throw new AppError(httpStatus.BAD_REQUEST, 'Failed to create user');
}
// set id , _id as user
payload.id = newUser[0].id;
payload.user = newUser[0]._id; //reference _id
// create a faculty (transaction-2)
const newFaculty = await Faculty.create([payload], { session });
if (!newFaculty.length) {
throw new AppError(httpStatus.BAD_REQUEST, 'Failed to create faculty');
}
await session.commitTransaction();
await session.endSession();
return newFaculty;
} catch (err: any) {
await session.abortTransaction();
await session.endSession();
throw new Error(err);
}
};
const createAdminIntoDB = async (password: string, payload: TAdmin) => {
// create a user object
const userData: Partial<TUser> = {};
//if password is not given , use deafult password
userData.password = password || (config.default_password as string);
//set student role
userData.role = 'admin';
const session = await mongoose.startSession();
try {
session.startTransaction();
//set generated id
userData.id = await generateAdminId();
// create a user (transaction-1)
const newUser = await User.create([userData], { session });
//create a admin
if (!newUser.length) {
throw new AppError(httpStatus.BAD_REQUEST, 'Failed to create admin');
}
// set id , _id as user
payload.id = newUser[0].id;
payload.user = newUser[0]._id; //reference _id
// create a admin (transaction-2)
const newAdmin = await Admin.create([payload], { session });
if (!newAdmin.length) {
throw new AppError(httpStatus.BAD_REQUEST, 'Failed to create admin');
}
await session.commitTransaction();
await session.endSession();
return newAdmin;
} catch (err: any) {
await session.abortTransaction();
await session.endSession();
throw new Error(err);
}
};
export const UserServices = {
createStudentIntoDB,
createFacultyIntoDB,
createAdminIntoDB,
};
```

It is designed to interoperate fully with Java but offers several distinct advantages that make it a compelling choice for Android development. Here, we will delve into the various benefits of using Kotlin over Java for Android development, encompassing areas such as language features, productivity, safety, and community support.
## 1. Conciseness
One of the most praised advantages of Kotlin is its conciseness. Kotlin reduces the amount of boilerplate code that developers have to write, which can be particularly verbose in Java. For instance, data classes in Kotlin automatically generate methods like equals(), hashCode(), toString(), and copy(), which in Java would require extensive manual coding.
## 2. Null Safety
Kotlin addresses one of the most common issues in Java development: null pointer exceptions (NPEs). In Kotlin, the type system distinguishes between nullable and non-nullable references, which helps catch potential null pointer exceptions at compile time.
## 3. Extension Functions
Kotlin allows developers to extend existing classes with new functionality without inheriting from them or using design patterns such as Decorator. This is achieved through extension functions, which make the code more modular and reusable.
## 4. Coroutines for Asynchronous Programming
Kotlin introduces coroutines, which provide a simpler and more efficient way to handle asynchronous programming compared to Java’s traditional approach using threads and callbacks. Coroutines enable developers to write asynchronous code that is sequential and easy to read.
## 5. Interoperability with Java
Kotlin is designed to be fully interoperable with Java, allowing developers to use Java libraries and frameworks within Kotlin projects. This ensures that existing Java codebases can be incrementally migrated to Kotlin without a complete rewrite, facilitating a smoother transition.
## 6. Enhanced Type Inference
Kotlin’s type inference capabilities are more advanced than those in Java. This allows developers to write cleaner and more concise code without explicitly specifying types when they can be inferred by the compiler.
## 7. Default Arguments and Named Parameters
Kotlin supports default arguments and named parameters, which enhance the flexibility and readability of function calls. This reduces the need for multiple overloaded methods to achieve the same functionality.
## 8. Smart Casts
Kotlin’s smart cast feature automatically casts types after a type check, eliminating the need for explicit casting. This reduces redundancy and potential casting errors.
## 9. Sealed Classes
Kotlin introduces sealed classes, which are a powerful tool for representing restricted class hierarchies. Sealed classes ensure that all possible subclasses are known at compile time, making it easier to handle exhaustive when expressions.
## 10. Community and Ecosystem
Since its official support by Google, Kotlin has seen rapid adoption and growth within the Android development community. The Kotlin community is active and vibrant, contributing a wealth of libraries, tools, and resources. JetBrains, the creator of Kotlin, continually enhances the language and its tooling, ensuring it remains modern and efficient.
The growing ecosystem around Kotlin includes frameworks like Ktor for building web applications and kotlinx.coroutines for coroutine-based programming, as well as extensive support in IDEs like IntelliJ IDEA and Android Studio.
## Conclusion
Kotlin offers numerous advantages over Java for Android app development, including enhanced conciseness, null safety, advanced type inference, and powerful features like coroutines and extension functions. These benefits lead to more readable, maintainable, and reliable code. Kotlin’s seamless interoperability with Java ensures that existing Java codebases can be easily integrated and incrementally migrated, allowing developers to adopt Kotlin without a complete overhaul of their projects. The active community and robust ecosystem further reinforce Kotlin’s position as a modern and efficient language for Android development. | chariesdevil |

Imagine a game of billiards. An intermediate player teaches a total beginner how the rules work, and they play a round. The beginner wins.
This is a classic case of **beginner’s luck**: when circumstances grant an inexperienced person success that is disproportionate to their novice skill level.
Beginner’s luck usually gives people a false sense of confidence. As a new coder, imagine you solved your first 10 coding challenges with 100% success rate, or you wrote your first five programs without a single bug. This is all well and great, but it’s circumstantial — and it does run out before too long.
Losing your beginner’s luck can be disheartening. Things don’t come easily anymore, and unfortunately, this is the point when some beginners quit. It may seem counterintuitive, but losing your luck means you’ve entered a more productive part of your learning journey.
Today I’ll talk about the idea of the **productive struggle** — and explain why losing your luck is actually one of the most important parts of the learning curve:
1. Why beginner’s luck ends (and why that’s a good thing)
2. Embracing the entire learning curve
3. Setting up for long term success
## Why beginner’s luck ends
The only way to master any skill is with time and plenty of practice (and failures). This is especially true for coding.
When I first started learning to use pointers in C, it seemed easy. But over the course of a few weeks, I realized pointers were a significant and even mind-bending concept that would take months and years to master.
As soon as beginner’s luck starts running out, you may feel that you don’t know what you’re doing wrong. You can feel stuck and **lose momentum.** You may even feel your progress is moving backwards.
What you may not realize is that this shift is not a matter of luck at all — you’ve just reached a **new phase of the learning curve**.
Learning to program is **like hiking up a mountain** with different paths. All the paths reach the same summit, but you’ll experience **steepness in different parts** of the journey. Every path has its own challenges. You may not know when you’ll encounter a steep incline, but when you do, it’s going to be an arduous climb (and you’ll have to persist despite it).
## The steeper part of the learning curve
Some developers hit dips in their learning and think, “Coding isn’t for me.” But this is far from the truth. Everyone encounters obstacles. It may feel counterintuitive, but struggling in the learning process is actually very effective for your learning.
There’s actually a term educators use for this: **productive struggle. **By actively engaging in challenging (even uncomfortable) learning activities, our brains even produce myelin, which encourages skill retention and effective signaling in the brain.
There’s a sweet spot between ease and overwhelm, where you need to be challenged by a concept in order to make a breakthrough in your learning. However, to make the most of that sweet spot, it’s essential that you:
- Remain clear on what your goal is
- Get support when you need it
- Have a healthy relationship with failure
A lot of people even **give up programming prematurely** because they hit an incline and don’t have mentors to tell them they’re a healthy part of the learning process. Imagine someone started to lift weights and gave up because they were sore, and thought this meant they weren’t good. This is when a coach should be there to tell you, “Hey, becoming sore is part of the process. It’s normal and means you’re growing — that’s literally the feeling of your muscles breaking down and growing back stronger. In some cases, the soreness won’t go away for a week, but you’ll still keep getting better.”
Any professional developer gets stuck on countless concepts and bugs throughout their coding journey. The only difference is that successful programmers persisted. And sometimes, persistence just means taking a nap (in other words, taking a break).
## It’s not the wrong path. Keep pushing ahead.
When you hit a roadblock and lose momentum, it’s best to stick to that path that you’re already on than to abandon your progress for a different one.
I’ve seen many new developers switch programming languages just because they lost momentum. This can be tempting if you’re self-taught and have an abundance of choices available when it comes to learning your first programming languge.
Switching tracks like this ultimately slows your growth, making you the jack of all trades and **master of none**. If you take up Python and get stuck, you might think, “Maybe I would’ve been better off with Java,” and switch over. At first, you might find that you’re picking up Java faster, further validating your belief that Python was the wrong choice. In reality, the only reason you’d feel more comfortable with the new language in this situation is because you’re **repeating the beginner steps in another language.** (After all, the skills you learn in one language do transfer over to the other, which is why it doesn’t really matter which programming language you learn first).
No matter which language, skill, or concept you’re learning, you can expect to hit a steep incline sooner or later (and several times). When you do, your key to success is maintaining resilience and embracing the struggle.
## Luck alone won’t make you a pro
When I learned my first programming language, I was confident that I could build **complex apps like Microsoft Word** quickly. After all, this program would just need a few functionalities, of which I already knew a few (how to get input and save a file).
As soon as I tried building a text editor myself, the reality hit quickly that it wasn’t that easy. In reality, every successful product is a complex software backed by a lot of engineering. And while building basic programs is a good start, it’s only the beginning of building job-ready skills.
It can be easy to believe that if you’ve picked up a language quickly, you can become a professional developer quickly, too. The truth is that successful developers have gone much farther and spent more time not only learning a language. They’ve understood the core of data structures and algorithms that help them solve problems optimally. As a professional developer, your main task is not even using a programming language: **it’s problem-solving**. In the problem-solving process, you really only use the programming language at the very end, to translate your solution into executable instructions for the computer.
Coding is an amazing career, and it will constantly challenge you. Once you’re in the professional world, you’ll need to learn to leverage more complex computer science skills to apply your current tools to the fullest. You can worry about these more complex skills later down the line, but in the meantime, I hope you **enjoy the learning process** — even when you have to move uphill.
## Braving the summit
**You don’t need luck** to succeed in your coding journey. The true key to success is persistence.
Inclines in the learning curve can be frustrating and demoralizing, yet we all encounter them — and they’re a good thing. Every professional programmer I’ve talked to can recount days where they were stuck because of an obstacle in their learning, despite endless Googling and nail-biting.
Even if you’re stuck, remember that you’re still on the same path as the greats. **Take a break, ask for help**, or retrace your steps to find the root that’s tripping you up. When you’re making mistakes or feeling stuck, breakthroughs are just around the corner. You will find the way forward as long as you try.

1,886,895 | Docker Caching Strategies for Efficient Image Builds | Docker caching is a crucial aspect of efficient image builds in containerized environments. By... | 0 | 2024-06-13T11:45:43 | https://dev.to/platform_engineers/docker-caching-strategies-for-efficient-image-builds-kd3 | Docker caching is a crucial aspect of efficient image builds in containerized environments. By optimizing caching strategies, developers can significantly reduce build times and improve overall productivity. This blog post delves into the technical aspects of Docker caching, exploring various strategies and their implementation.
### Understanding Docker Caching
Docker caching is based on the concept of layers. Each instruction in a Dockerfile creates a new layer, and Docker uses these layers to build the final image. When a layer is unchanged, Docker reuses the cached version, reducing the build time.
### Basic Caching Strategy
The basic caching strategy involves using the `--no-cache` flag when running the Docker build command. This flag forces Docker to rebuild all layers, ensuring that any changes are reflected in the final image.
```bash
docker build --no-cache -t my-image .
```
### Layer Caching
Layer caching is a more efficient strategy that reuses unchanged layers. Docker caches each layer based on its hash, which is calculated from the layer's contents. When a layer's contents remain unchanged, Docker reuses the cached layer.
To implement layer caching, use the `--cache-from` flag, specifying the base image or a previous build as the cache source.
```bash
docker build --cache-from my-base-image -t my-image .
```
### Cache Mounting
Cache mounting is a strategy that mounts the cache directory from a previous build, allowing Docker to reuse cached layers. This approach is particularly useful when building images on a continuous integration/continuous deployment (CI/CD) pipeline.
To mount the cache, use the `--mount` flag with the `type=cache` option.
```bash
docker build --mount type=cache,target=/root/.cache -t my-image .
```
### Cache Sharing
Cache sharing involves sharing the cache between multiple builds. This strategy is useful when building multiple images that share common layers.
To share the cache, use a Docker volume to persist the cache across builds.
```bash
docker volume create docker-cache
docker build --mount source=docker-cache,target=/root/.cache -t my-image .
```
### Cache Invalidation
Cache invalidation is crucial to ensure that changes are reflected in the final image. Docker provides several mechanisms for cache invalidation, including:
1. **Layer Hash**: Docker recalculates the layer hash when the layer's contents change, invalidating the cache.
2. **Build Arg**: Using build arguments (`--build-arg`) can invalidate the cache when the argument value changes.
3. **Environment Variables**: Changing environment variables can also invalidate the cache.
Docker caching plays a vital role in optimizing image builds and reducing build times. By implementing efficient caching strategies, [platform engineers](www.platformengineers.io) can improve the overall efficiency of their containerized environments.
### Conclusion
[Docker](https://platformengineers.io/blog/best-practices-for-writing-dockerfiles/) caching is a critical aspect of efficient image builds. By understanding the different caching strategies and implementing them effectively, developers can significantly reduce build times and improve productivity. Whether using layer caching, cache mounting, cache sharing, or cache invalidation, Docker caching provides a powerful toolset for optimizing containerized environments. | shahangita | |

1,886,893 | Why are they avoiding using require and using import in JavaScript | Differences One of the differences between require and import is that require is used to load... | 0 | 2024-06-13T11:41:19 | https://dev.to/doccaio/why-are-they-avoiding-using-require-and-using-import-in-javascript-k70 |
**Differences**
One of the differences between require and import is that require is used to load modules in Node.js, while import is used to import modules in JavaScript.
Another important difference is that require returns an object, while import returns a reference to the module.
This means that when you use require, you can assign the return to a variable and use that variable to access the module's properties and methods.
With import you need to directly access the properties and methods of the imported module, in short, require is used to load modules in Node.js and is a built-in function, while import is used to import modules in JavaScript and is a keyword from ECMAScript 6, and is not natively supported by Node.js.
**Require**
O require é uma função built-in do Node.js e é usado para carregar módulos de arquivos externos e pacotes instalados globalmente. Ele também pode ser usado para carregar módulos internos do Node.js, como http e fs.
Exemplo de importação com require:
```Js
// módulo "myModule.js"
const myVariable = 'Hello World';
function myFunction() {
console.log('This is my function');
}
module.exports = { myVariable, myFunction }
// arquivo "main.js"
const myModule = require('./myModule');
console.log(myModule.myVariable); // imprime "Hello World"
myModule.myFunction(); // imprime "This is my function"
```
## **Import**
Import is a JavaScript keyword, it was introduced from the ECMAScript 6 (ES6) version and is not supported by Node.js, to use this functionality it is necessary to use a transpiler that can transpile the code to a version that Node.js understands.
Import example with import:
```js
// módulo "myModule.js"
export const myVariable = 'Hello World';
export function myFunction() {
console.log('This is my function');
}
// arquivo "main.js"
import { myVariable, myFunction } from './myModule';
console.log(myVariable); // imprime "Hello World"
myFunction(); // imprime "This is my function"
```
However, it is important to note that JavaScript has evolved a lot in recent years with the introduction of ECMAScript 6 (ES6) and later versions. One of the key additions was the introduction of ES6 modules, which provide a clearer and more powerful syntax for importing and exporting modules.
With the introduction of ES6 modules, many developers have adopted this new syntax as an alternative to require, especially in modern projects. ES6 modules offer advanced features such as named imports, asynchronous imports, and dynamic imports that can bring benefits in terms of code readability, maintainability, and performance.
Therefore, rather than avoiding require, it is more accurate to say that developers are preferring to use ES6 modules whenever possible, especially in modern JavaScript projects and environments that support this syntax. However, in older environments or in specific cases, require is still widely used and remains a valid option for including modules in JavaScript.
Using import instead of require in JavaScript has some advantages, especially when it comes to modern projects that make use of ECMAScript 6 (ES6) features and development environments that support modules. Some reasons why import is preferred in many cases:
- Clearer and more concise syntax.
- Controlled import scope.
- Native support for modules.
- Asynchronous and dynamic imports.
- Construction and bundling tools.
However, it is important to mention that in certain contexts, such as older projects or environments that do not natively support ES6 modules, it may still be necessary to use require. require is a commonly used function in environments like Node.js and is supported by package management systems like npm. Therefore, the choice between import and require depends on the project context, the supported ECMAScript versions, and the specific requirements of the development environment.

1,886,885 | Mastering Market Research and Competitive Analysis: Strategies for Business Success | In today's competitive business environment, products that fail to meet customer needs and desires... | 0 | 2024-06-13T11:30:23 | https://dev.to/linda0609/mastering-market-research-and-competitive-analysis-strategies-for-business-success-46cf | In today's competitive business environment, products that fail to meet customer needs and desires often struggle in the market, negatively impacting sales revenue. To better understand consumer behavior, market research and analytics are essential tools. Corporate leaders use these insights to craft competitive strategies, often with the assistance of market research consulting partners. This post will delve into the processes of conducting market research and competitive analysis.
What is Market Research?
Market research involves gathering valuable customer insights through interviews, surveys, social listening, and media coverage analysis. Businesses often hire market research consulting firms to enhance their understanding of consumer preferences. These insights enable companies to refine their pricing strategies and marketing efforts, attracting new customers while retaining existing ones. Data-driven strategies are less prone to human error, a common issue in traditional business development methods.
Market research helps minimize the risks associated with product launches. Marketing analytics companies provide transparent, flexible reports that identify the promotional strategies most effective in engaging target customer profiles.
What is Competitive Analytics?
Competitive analytics uses statistical modeling and automation technologies to develop strategies for outperforming competitors and increasing market share. Market research and analytics firms can help optimize internal operations to boost competitiveness. Efficient resource allocation is critical; a company that manages its resources better than its competitors will likely succeed. By reducing wasteful practices, businesses can offer more competitive pricing.
Understanding competitors' strategies is also crucial. Although direct information is often unavailable, [market research consulting](https://us.sganalytics.com/market-research/) teams use machine learning (ML) models to analyze competitors’ public communications. ML-driven predictive analytics help forecast competitors' growth plans, providing valuable foresight.
Conducting Market Research and Competitive Analysis
The first step in conducting market research or competitive analysis is to clearly define your goals. Without clear objectives, the research process can become aimless and disappointing. Next, consider the available technologies and their financial implications. Regional companies might benefit from standard marketing analytics tools, whereas global firms require scalable, automated software for high-quality reporting. Setting a timeframe is essential for tracking progress and preventing scheduling conflicts. Financial planning also hinges on a clear timeline, particularly regarding interest calculations on borrowed capital.
Businesses have unique objectives, risk profiles, and data processing needs. Understanding the different market research and competitive analysis techniques is crucial.
Types of Market Research Services
1. Primary Research :
Primary research involves direct interactions, such as interviews with customers, suppliers, and employees. This original data enhances the quality of competitive analytics and grants ownership rights to the resulting databases. Primary research is valuable for creating thought leadership content, establishing authority, and gaining unique strategic insights. This data often integrates into whitepapers, case studies, and investor relations disclosures, bolstering stakeholder trust.
2. Secondary Research :
Secondary research relies on publicly available information gathered by others, including social media, magazines, discussion forums, and news publications. Although secondary research can be cost-effective, it requires careful source evaluation to avoid manipulative content and misinterpretation. Consulting firms help assess the credibility of various sources, ensuring reliable insights.
3. Manual Research :
Small businesses and nascent social media accounts can use simple analytics to assess growth, revenue, and competitiveness. However, manual research is prone to human error and is becoming less relevant as advanced analytics tools become more prevalent.
4. Automated Research :
Machine learning and artificial intelligence enable automated market research and analytics, offering continuous data gathering, validation, and cleaning. These technologies save time, reduce human effort, and eliminate ambiguity in data validation, providing extensive, reliable data for analysis.
5. Qualitative Research :
Qualitative research involves analyzing textual data such as social media posts, consumer reviews, and discussion forums. Natural language processing (NLP) algorithms facilitate sentiment analysis, making it easier to categorize and understand unstructured data.
6. Quantitative Research :
Quantitative research deals with structured numerical data, such as customer ratings. It is used in financial modeling and total quality management (TQM). This type of research is less resource-intensive and focuses on structured, standardized data, making it efficient for specific business objectives.
Types of Competitive Analytics
1. Internal Competitive Research and Analysis :
This approach examines how a company manages its internal operations, such as supply chains, professional networks, business units, and investor relations. For example, a company facing high employee attrition might use competitive analytics to understand and address the underlying issues.
2. External Competitive Analytics :
External analytics focus on factors outside a company's control, such as economic conditions and natural disasters. This broader scope helps companies anticipate and mitigate risks associated with external market forces.
3. Competitor Analytics :
Competitor analysis is more focused, concentrating on direct rivals. It involves benchmarking performance against competitors, providing fast and resource-efficient insights for strategic planning.
4. Descriptive and Diagnostic Analysis :
Descriptive analytics review past performance, while diagnostic analytics identify ways to improve productivity and efficiency. These analyses help companies learn from previous strategies and solve encountered problems.
5. Predictive and Prescriptive Analytics :
Predictive analytics use ML to forecast market trends, consumer preferences, regulatory changes, and competitor strategies. Prescriptive analytics provide actionable solutions to address potential risks identified by predictive models, helping companies prepare for future challenges.
Conclusion
Market research and competitive analysis are vital for understanding customer insights and enhancing business strategies. Primary and secondary research offer different benefits, while qualitative and quantitative methods cater to various data structures. Automation has largely replaced manual data collection, making processes more efficient. When considering market research and competitive analysis, it's crucial to understand these methodologies and choose the right tools for your business needs.

Hoje quero compartilhar com vocês alguns pontos importantes sobre as ferramentas de Inteligência Artificial, especialmente os Modelos de Linguagem de Grande Porte (LLMs), quando utilizadas no ensino de fundamentos de software em cursos de TI. Este tema é essencial não apenas para desenvolvedores, sejam juniores ou seniores, mas também para CEOs que estão liderando equipes de tecnologia e inovação.
A capacidade impressionante de gerar código de uma IA é fascinante, mas vale lembrar que nada substitui a experiência e o conhecimento de um desenvolvedor experiente. A criatividade, o pensamento crítico e a habilidade de resolver problemas complexos ainda são atributos humanos que a IA não consegue replicar completamente.
Embora as ferramentas de IA possam ajudar a acelerar processos, elas não garantem que os requisitos do projeto sejam atendidos na íntegra. É crucial que os desenvolvedores tenham um sólido conhecimento dos fundamentos de software para validar e verificar o código gerado. Isso assegura que o resultado final seja funcional e de alta qualidade.
Uma das limitações dos modelos LLMs é a falta de contexto nas explicações que elas fornecem. Para os aprendizes, isso pode ser um obstáculo na compreensão dos conceitos de software. É importante que o aprendizado seja acompanhado por um educador ou mentor que possa oferecer o contexto necessário para uma compreensão completa.
Ao interagir com IA, é fundamental proteger suas informações pessoais. Questões de privacidade e segurança devem ser uma prioridade para todos os usuários, garantindo que dados sensíveis não sejam expostos ou mal utilizados.
As ferramentas como ChatGPT têm muito a oferecer, mas devemos usá-las com discernimento. Entender suas capacidades e limitações, além de manter um conhecimento sólido dos fundamentos de software, é a chave para garantir a qualidade e a segurança dos projetos.
Para os CEOs, investir no desenvolvimento contínuo das habilidades de suas equipes e promover um ambiente de aprendizado contínuo é essencial. IAs são ótimas aliadas, mas a expertise humana continuará sendo o diferencial competitivo.

Selecting the right UI component library is more than a technical decision; it’s a journey that shapes the development process, influences user experience, and ultimately impacts the project's success. Over the years, I have faced countless challenges and learned invaluable lessons that have guided my approach to choosing the best UI components. In this blog post, I will share my journey, insights, and experiences, highlighting the factors to consider and the best practices I've discovered along the way.
## The Early Days: Bootstrap and React-Bootstrap
Eight years ago, I embarked on a project that relied heavily on Bootstrap, which was incredibly popular at the time. Bootstrap's simplicity and ease of use made it a go-to choice for many developers. We chose React-Bootstrap for its familiar syntax and seamless integration with React. However, we quickly realized that React-Bootstrap lacked many essential components. This forced us to depend on numerous third-party libraries, leading to significant maintenance challenges. Managing these dependencies was like juggling too many balls in the air, and we often found ourselves struggling to keep everything in sync. It was a chaotic yet enlightening experience, teaching me the importance of having a comprehensive and cohesive component library.
## Discovering Ant Design (Antd)
Determined to find a better solution, I delved into extensive research and discovered Ant Design (Antd). The moment I stumbled upon Antd, it felt like finding a treasure chest. Antd's extensive collection of components seemed to cover almost every need we could think of. The library's robustness and comprehensive documentation made it a promising choice. However, as with every treasure, there were hidden pitfalls. The documentation was predominantly in Chinese, posing a challenge for English speakers. Moreover, customizing themes in Antd was more complex than anticipated, leading to frustrations and delays. Despite these challenges, Antd taught me the value of having a rich component library and the importance of thorough documentation.
## Finding MUI
As the project evolved, we needed a highly customized data grid, and that's when I stumbled upon MUI (formerly Material-UI). MUI's data grid, complex UI components, and highly configurable theme customization were like a breath of fresh air. It offered the flexibility and power we needed. However, as the project grew, we encountered performance issues due to CSS, and our UI/UX team struggled to implement their designs within MUI's constraints. The constant tug-of-war between adhering to MUI's limitations and meeting the UI/UX team's vision led to conflicts and compromises. This phase of the journey was a bittersweet reminder of the delicate balance between functionality and performance.
## The Headless and Unstyled Revelation
Faced with these challenges, I considered building our own components from scratch. But the reality of tight deadlines and limited resources made this an impractical solution. Then, a friend introduced me to headless and unstyled components. Libraries like React Aria and Radix offered components without any predefined styles, allowing us to create highly customized designs tailored to our exact needs. We paired these headless components with Tailwind CSS for styling, which provided the flexibility and consistency we craved. This revelation was a game-changer, opening up new possibilities for creativity and customization.
## Tackling Tailwind's Complexity
While Tailwind CSS offered great flexibility, managing variants and long CSS class lists quickly became cumbersome. It felt like navigating through a labyrinth of CSS classes. This is when I discovered Tailwind Variant and CVA. These tools simplified the process of managing Tailwind CSS, significantly improving our developer experience (DX). For our data grid needs, we used TanStack DataGrid, a robust headless component that we customized to match our design standards. This combination allowed us to maintain a high level of customization without sacrificing performance or maintainability. This phase of the journey was about finding harmony in the midst of complexity.
## Leveraging Open Source Repositories
Throughout my journey, open-source repositories were a beacon of inspiration and best practices. For instance, I closely examined MUI's source code to understand their coding standards, folder structure, and theme customization techniques. Similarly, I learned about CVA from Shadcn's source code and discovered the power of Tailwind Variant through NextUI's repository. These open-source projects provided a wealth of knowledge and inspiration, enabling us to adopt best practices and streamline our development process. This journey taught me the value of community and collaboration in the development world.
## Real-World Scenarios and Best Practices
### When to Choose Headless and Unstyled Libraries
- **Timeline**: When you have sufficient time to invest in custom design.
- **Client Budget**: When you have a generous budget to accommodate the flexibility needed.
- **Number of Resources**: When you have a skilled team of developers who can handle the complexity.
- **Organization Design Complexity**: When your design requirements are highly customized and specific.
- **Project Type**: When the project is not a typical dashboard but requires unique design elements.
### When to Choose Pre-Styled Libraries
- **Timeline and Budget**: When you have limited time and budget constraints.
- **Design Requirements**: When design is not a primary concern or can be compromised.
- **Project Type**: For dashboard projects, proofs of concept (POCs), or projects where speed and simplicity are paramount.
## Key Takeaways
- **Use Tailwind with Unstyled Components**: Pairing Tailwind CSS with unstyled component libraries allows for beautiful, custom designs that align with your project's specific needs.
- **Enhance DX with Tools**: Utilize tools like CVA and Tailwind Variant to manage Tailwind CSS efficiently, reducing complexity and improving maintainability.
- **Document with Storybook**: Storybook is invaluable for component documentation, enhancing developer experience and ensuring consistency across the project.
- **Create Wrapper Components**: When using third-party components, create wrapper components to facilitate future replacements and maintain flexibility.
## Final Thoughts
Selecting the best UI component library is a journey that involves careful consideration of various factors such as timeline, budget, resources, design complexity, team expertise, and project type. My experiences have taught me the value of leveraging open-source repositories, embracing headless and unstyled components, and continuously refining our approach based on project requirements.
As a React expert with years of experience, I understand the emotional ups and downs of navigating these decisions. Each project brings unique challenges and opportunities for growth. By sharing my journey, I hope to provide valuable insights and guidance to fellow developers facing similar dilemmas.
This journey is not just about finding the right tools; it's about growing as a developer, understanding the nuances of each project, and continuously striving for excellence. Whether you're just starting out or are a seasoned developer, I hope my experiences inspire you to make informed decisions and embark on your own journey of discovery and innovation. | webdevlapani | |

The time has come for Part 2 in the series of creating a Serverless Connected BBQ as SaaS. In this second post we'll look into user creation, authentication, and authorization. We'll setup idP using Cognito User Pool, and create an event-driven system to store data in our user service. We'll also start building out the frontend part so users can interact with the solution.
If you have not already checked it out, here is [part 1](https://dev.to/aws-builders/building-a-serverless-connected-bbq-as-saas-part-1-59gn).
## User in a SaaS
In the connected BBQ IoT SaaS solution, I have opted in for a user management strategy that ensure secure and efficient handling of user data. We leverage AWS Cognito User Pools, enhanced with custom attributes to store tenant-specific information, coupled with DynamoDB for external metadata storage. This approach streamlines user authentication and authorization and maintains the scalability and flexibility needed.
### Single User Pool with Custom Attributes
Our primary strategy involves using a single Cognito User Pool, enriched with custom attributes to capture tenant information. Each user is assigned attributes that identify their tenant, enabling the system to differentiate and manage users across various organizations within the same pool. This approach simplifies user management by centralizing all users in one pool while still allowing for tenant-specific operations.
### External Metadata Storage
To complement our user pool strategy, we store metadata about users in an external DynamoDB table. This can include information such as user preferences, and additional tenant-specific data that might not be suitable for storage within Cognito. This also enables a easy listing of users per tenant, and a quick way to fetch and display user information, instead of querying Cognito. In this solution users will update information in the user service, that stores it in DynamoDB, changes are then reflected into Cognito.
### One User Pool per Tenant
Another common approach in SaaS user management is to use one Cognito User Pool per tenant. This method provides a very strong isolation between tenants, simplifying access control and data segregation.
### Thoughts
By using a single user pool with custom attributes and external metadata storage, we have a balanced approach that combines the advantages of centralized management and flexible.
## Architecture Overview
We'll create two parts when it comes to user management, the idP which consists of Cognito User Pool and a user service that will be storing user information and relationships. When a user sign up for our solution the user pool will invoke a Lambda function when the user has been confirmed `Post Confirmation`. The function will put a an event on the application event-bus that a user was created. The user service will react on this event and store information about the user in a DynamoDB table. User service ends by posting a new event on the bus saying a new user was created.
We will also start creating our dashboard, which is a React application. We'll let users sign up for our solution, login / logout, and see some basic information about their profile.
## Create EventBridge
We will use the event-bus design with a single central bus, this design pattern is a good start which makes it easy to expand with more services, and in a later stage maybe move to a multi-bus approach. Starting with a single central bus setup is normally what I recommend. So let's introduce our common stack that will contain our centrally managed resources.
``` yaml
AWSTemplateFormatVersion: "2010-09-09"
Transform: "AWS::Serverless-2016-10-31"
Description: Connected BBQ Application Common Infra
Parameters:
Application:
Type: String
Description: Name of owning application
Default: bbq-iot
Resources:
EventBridgeBus:
Type: AWS::Events::EventBus
Properties:
Name: !Sub ${Application}-application-eventbus
Tags:
- Key: Application
Value: !Ref Application
Outputs:
EventBridgeName:
Description: The EventBus Name
Value: !Ref EventBridgeBus
Export:
Name: !Sub ${AWS::StackName}:eventbridge-bus-name
EventBridgeArn:
Description: The EventBus ARN
Value: !GetAtt EventBridgeBus.Arn
Export:
Name: !Sub ${AWS::StackName}:eventbridge-bus-arn
```
## Create idP setup
First of all we need to create our idP, for this we use Cognito User Pool. E-mail will be used as username, which also need to be verified. Password policy is created and also a schema where the user need to specify e-mail and name, in the schema we also add a field tenant that will be populated by our system.
When a user sign up, e-mail, password, and name will be added by the user. Cognito will then validate the e-mail and when that is done a Lambda function will be invoked that adds a message on the event-bus.
So let's start by creating the User Pool
``` yaml
AWSTemplateFormatVersion: "2010-09-09"
Transform: "AWS::Serverless-2016-10-31"
Description: Connected BBQ Application idP setup Authentication
Parameters:
ApplicationName:
Type: String
Description: The application that owns this setup.
HostedAuthDomainPrefix:
Type: String
Description: The domain prefix to use for the UserPool hosted UI <HostedAuthDomainPrefix>.auth.[region].amazoncognito.com
CommonStackName:
Type: String
Description: The name of the common stack that contains the EventBridge Bus and more
Resources:
UserPool:
Type: AWS::Cognito::UserPool
Properties:
UserPoolName: !Sub ${ApplicationName}-user-pool
UsernameConfiguration:
CaseSensitive: false
UsernameAttributes:
- "email"
AutoVerifiedAttributes:
- email
Policies:
PasswordPolicy:
MinimumLength: 12
RequireLowercase: true
RequireUppercase: true
RequireNumbers: true
RequireSymbols: true
AccountRecoverySetting:
RecoveryMechanisms:
- Name: "verified_email"
Priority: 1
- Name: "verified_phone_number"
Priority: 2
Schema:
- Name: email
AttributeDataType: String
Mutable: false
Required: true
- Name: name
AttributeDataType: String
Mutable: true
Required: true
- Name: tenant
AttributeDataType: String
DeveloperOnlyAttribute: true
Mutable: true
Required: false
```
To be able to interact with the User Pool from our Webb application we also need to create a User Pool Client. In the webb application we will use Amplify and Amplify UI for user sign up and sign in. For this to work properly it's important that we don't generate an secret, as that will then block Amplify UI. So we need `GenerateSecret: False` set. Now let's add the client to the template from before.
``` yaml
UserPoolClient:
Type: AWS::Cognito::UserPoolClient
Properties:
UserPoolId: !Ref UserPool
GenerateSecret: False
AllowedOAuthFlowsUserPoolClient: true
CallbackURLs:
- http://localhost:3000
#- !Sub https://${DomainName}/signin
AllowedOAuthFlows:
- code
- implicit
AllowedOAuthScopes:
- phone
- email
- openid
- profile
SupportedIdentityProviders:
- COGNITO
```
The final part is to add the Lambda function for the post confirmation hook and integrate that with the User Pool. When posting a event to the event-bus we will use the metadata / data pattern.
``` json
{
"metadata": {
"domain": "idp",
"application": "application_name",
"event_type": "signup",
"version": "1.0",
},
"data": {
"email": "user e-mail",
"userName": "user name",
"name": "name",
"verified": "verified",
"status": "status",
},
}
```
Now let's add the Lambda function to the template and set the User Pool to call it. We also need to add Lambda Permission so the User Pool is allowed to invoke the function.
``` yaml
PostSignUpHook:
Type: AWS::Serverless::Function
Properties:
AutoPublishAlias: "true"
CodeUri: ./PostSignUpLambda
Handler: hook.handler
AssumeRolePolicyDocument:
Version: 2012-10-17
Statement:
- Effect: Allow
Principal:
Service:
- lambda.amazonaws.com
Action:
- sts:AssumeRole
Policies:
- EventBridgePutEventsPolicy:
EventBusName:
Fn::ImportValue: !Sub ${CommonStackName}:eventbridge-bus-name
Environment:
Variables:
EventBusName:
Fn::ImportValue: !Sub ${CommonStackName}:eventbridge-bus-name
ApplicationName: !Ref ApplicationName
PostSignUpHookPermission:
Type: AWS::Lambda::Permission
Properties:
Action: lambda:InvokeFunction
FunctionName: !GetAtt PostSignUpHook.Arn
Principal: cognito-idp.amazonaws.com
UserPool:
Type: AWS::Cognito::UserPool
Properties:
.....
LambdaConfig:
PostConfirmation: !GetAtt PostSignUpHook.Arn
```
The code for the Lambda function is not that complicated, it will just post a message to the event-bus.
``` python
import boto3
import os
import json
def handler(event, context):
application_name = os.environ["ApplicationName"]
event_bus = os.environ["EventBusName"]
event_bus_client = boto3.client("events")
user_event = {
"metadata": {
"domain": "idp",
"application": application_name,
"event_type": "signup",
"version": "1.0",
},
"data": {
"email": event["request"]["userAttributes"]["email"],
"userName": event["userName"],
"name": event["request"]["userAttributes"]["name"],
"verified": event["request"]["userAttributes"]["email_verified"],
"status": event["request"]["userAttributes"]["cognito:user_status"],
},
}
response = event_bus_client.put_events(
Entries=[
{
"Source": f"{application_name}.idp",
"DetailType": "signup",
"Detail": json.dumps(user_event),
"EventBusName": event_bus,
},
]
)
return event
```
With that created the sign up flow for the User Pool is completed.
## Create User Service
The next part in the user handling is the User Service that will be used to store additional metadata about the users in the system. It will also be a crucial part in the permission and data isolation, that will be discussed in later parts.
When a user has signed up, we like to react on the event sent by the User Pool Lambda integration, and create a user in the user database. When user is stored we send an event about that on the bus for other services to react on.
So lets go ahead and create the state machine and user DynamoDB table.
``` yaml
AWSTemplateFormatVersion: "2010-09-09"
Transform: "AWS::Serverless-2016-10-31"
Description: Connected BBQ Application User Service

Parameters:
Entries:
- Source: ${ApplicationName}.user
DetailType: created
Detail.$: $
EventBusName: ${EventBridgeBusName}
End: true
```
## Create Dashboard
Let us now start creating our dashboard, that we will continue building on in this series. The dashboard is a react app created with `create-react-app`. For styling we will use [Tailwind CSS](https://tailwindcss.com/).
For user login and signup we will rely on Amplify, so first of all, let's create a small utils class that will check if a user is already logged in.
``` javascript
import { getCurrentUser } from "aws-amplify/auth";
export const isAuthenticated = async () => {
try {
await getCurrentUser();
return true;
} catch {
return false;
}
};
```
Next let's create our Login page, that we will route users to when they are not logged in.
``` javascript
import React, { useEffect } from "react";
import { Navigate, Route, Routes, useNavigate } from "react-router-dom";
import { isAuthenticated } from "../utils/auth";
import Header from "../components/Header";
import Footer from "../components/Footer";
import { Authenticator } from "@aws-amplify/ui-react";
import "@aws-amplify/ui-react/styles.css";
const Login = () => {
const navigate = useNavigate();
useEffect(() => {
isAuthenticated().then((loggedIn) => {
if (loggedIn) {
navigate("/dashboard");
}
});
}, [navigate]);
return (
<div className="min-h-screen flex flex-col">
<Header />
<main className="flex-grow flex items-center justify-center">
<Authenticator signUpAttributes={["name"]} loginMechanisms={["email"]}>
{({ signOut, user }) => (
<Routes>
<Route path="/" element={<Navigate replace to="/dashboard" />} />
</Routes>
)}
</Authenticator>
</main>
<Footer />
</div>
);
};
export default Login;
```
This will now create a UI and flow like this, which is the Amplify UI for Cognito User Pools.
To sign up the user click `Create Account` and fill in e-mail and password, in the next step the e-mail address must be verified.
After successful login it's possible to view user attributes on the `Profile` tab, also not that the login button now changes to logout.

But with an array of options at your disposal, choosing the most suitable authentication strategy can feel like navigating a labyrinth. This blog delves into the intricacies of sessions, tokens, JSON Web Tokens (JWTs), Single Sign-On (SSO), and OAuth in Laravel, equipping you with the knowledge to make an informed decision for your project.
## 1. Sessions: The Traditional Sentinel
Sessions, the time-tested guardians of user state, have long been a cornerstone of web application authentication. Laravel leverages cookies to store a session identifier that acts as a secret handshake between the user's browser and the server. This handshake grants access to user data stored on the server for the duration of the session, typically until the user logs out or their browser window closes.
```php
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Session;
class LoginController extends Controller
{
public function showLoginForm()
{
return view('auth.login');
}
public function login(Request $request)
{
$credentials = $request->only('email', 'password');
if (Auth::attempt($credentials)) {
// Authentication passed...
$request->session()->regenerate();
return redirect()->intended('dashboard');
}
return back()->withErrors([
'email' => 'The provided credentials do not match our records.',
]);
}
public function logout(Request $request)
{
Auth::logout();
$request->session()->invalidate();
$request->session()->regenerateToken();
return redirect('/');
}
}
```
### Advantages:
- **Simplicity:** Sessions are a well-established approach, making them easy to implement and integrate into existing Laravel applications.
- **State Management:** Session data allows you to maintain user progress and context throughout their browsing session, vital for features like shopping carts or multi-step forms.
### Disadvantages:
- **Scalability:** As session data resides on the server, large user bases can strain server resources and hinder scalability.
- **Security Concerns:** Session hijacking, where an attacker steals the session identifier, poses a potential security risk if not mitigated with proper security measures.
## 2. Tokens: The Stateless Samurai
Tokens, the stateless warriors of the authentication realm, offer a more modern approach. These self-contained units of information encapsulate user data and a cryptographic signature, eliminating the need for server-side session storage. This makes them ideal for:
- **API Authentication:** Tokens are lightweight and don't require session management, perfectly suited for the fast-paced world of APIs and microservices architectures.
- **Enhanced Security:** The cryptographic signature ensures data integrity, preventing unauthorized modifications during transmission.
However, tokens come with their own set of considerations:
- **Limited State Management:** Tokens themselves don't store user state, requiring additional mechanisms for complex scenarios that necessitate maintaining user progress across requests.
- **Increased Complexity:** Implementing robust token generation, verification, and authorization logic can add complexity to your application.
```php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use App\Models\User;
class AuthController extends Controller
{
// Register a new user and generate a token
public function register(Request $request)
{
$request->validate([
'name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:8|confirmed',
]);
$user = User::create([
'name' => $request->name,
'email' => $request->email,
'password' => Hash::make($request->password),
]);
$token = $user->createToken('auth_token')->plainTextToken;
return response()->json([
'access_token' => $token,
'token_type' => 'Bearer',
]);
}
// Login user and generate a token
public function login(Request $request)
{
$request->validate([
'email' => 'required|string|email',
'password' => 'required|string',
]);
$credentials = $request->only('email', 'password');
if (!Auth::attempt($credentials)) {
return response()->json(['message' => 'Unauthorized'], 401);
}
$user = Auth::user();
$token = $user->createToken('auth_token')->plainTextToken;
return response()->json([
'access_token' => $token,
'token_type' => 'Bearer',
]);
}
// Logout user and revoke token
public function logout(Request $request)
{
$request->user()->currentAccessToken()->delete();
return response()->json(['message' => 'Successfully logged out']);
}
// Get user details
public function me(Request $request)
{
return response()->json($request->user());
}
}
```
## 3. JWTs: The Compact and Secure Enforcer
JWTs (JSON Web Tokens) are a specific type of token format that elevates security and compactness to new heights. These tokens are JSON-encoded and digitally signed, offering several advantages:
- **Security:** The digital signature ensures data integrity and prevents tampering with the token's contents.
- **Compactness:** JWTs are lightweight and efficient, making them suitable for resource-constrained environments or mobile applications.
- **Self-Contained:** JWTs can optionally embed a limited amount of user data, reducing the need for additional server-side calls to retrieve user information.
While JWTs boast these benefits, they also have limitations:
- **Limited Server-Side Storage:** Similar to traditional tokens, JWTs don't store user state on the server, requiring additional mechanisms for complex scenarios.
- **Potential Decodability:** Depending on the implementation, the payload within a JWT might be decodable, revealing some user data.
Laravel Packages:
Laravel offers several robust packages like Tymon JWT or Lcobucci JWT to simplify JWT implementation, handling token generation, verification, and middleware integration seamlessly.
```php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Models\User;
use Tymon\JWTAuth\Facades\JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;
class AuthController extends Controller
{
public function login(Request $request)
{
$credentials = $request->only('email', 'password');
try {
if (! $token = JWTAuth::attempt($credentials)) {
return response()->json(['error' => 'invalid_credentials'], 400);
}
} catch (JWTException $e) {
return response()->json(['error' => 'could_not_create_token'], 500);
}
return response()->json(compact('token'));
}
public function register(Request $request)
{
$user = User::create([
'name' => $request->name,
'email' => $request->email,
'password' => bcrypt($request->password),
]);
$token = JWTAuth::fromUser($user);
return response()->json(compact('token'));
}
public function getAuthenticatedUser()
{
try {
if (! $user = JWTAuth::parseToken()->authenticate()) {
return response()->json(['user_not_found'], 404);
}
} catch (Tymon\JWTAuth\Exceptions\TokenExpiredException $e) {
return response()->json(['token_expired'], $e->getStatusCode());
} catch (Tymon\JWTAuth\Exceptions\TokenInvalidException $e) {
return response()->json(['token_invalid'], $e->getStatusCode());
} catch (Tymon\JWTAuth\Exceptions\JWTException $e) {
return response()->json(['token_absent'], $e->getStatusCode());
}
return response()->json(compact('user'));
}
}
```
## 4. SSO: The Unified Kingdom
SSO (Single Sign-On) establishes a kingdom of trust, allowing users to log in once and access a multitude of applications within a trusted network. This eliminates the need for repeated logins across different applications, streamlining the user experience.
While SSO offers convenience, it comes with its own considerations:
- **Third-Party Integration:** Implementing SSO often requires integrating with established providers like Okta or Auth0, adding an external dependency to your application.
- **Increased Complexity:** Setting up and maintaining an SSO infrastructure adds complexity to your project and introduces new security considerations.
```php
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Socialite;
class SSOController extends Controller
{
public function redirectToProvider()
{
return Socialite::driver('sso-provider')->redirect();
}
public function handleProviderCallback()
{
try {
$user = Socialite::driver('sso-provider')->user();
$authUser = $this->findOrCreateUser($user);
Auth::login($authUser, true);
return redirect()->intended('/home');
} catch (\Exception $e) {
return redirect('/login')->withErrors(['msg' => 'Unable to login using SSO.']);
}
}
private function findOrCreateUser($user)
{
$authUser = User::where('provider_id', $user->id)->first();
if ($authUser) {
return $authUser;
}
return User::create([
'name' =>'name' => $user->name,
'email' => $user->email,
'provider' => 'sso-provider',
'provider_id' => $user->id,
]);
```
## 5. OAuth: The Delegation Diplomat
OAuth, the skilled diplomat of the authentication world, facilitates controlled access to user data across different services. It allows users to grant access to their data on one platform (like a social media account) to another application. This is beneficial for:
**- Social Logins:**
Users can leverage their existing social media credentials to log in to your application, providing a convenient login option.
**- Third-Party Data Access:**
Granting access to specific user data from other services, such as accessing photos from a user's Facebook account.
However, OAuth also presents some challenges:
**- Security Concerns:**
Since OAuth relies on third-party providers, it introduces potential security risks.
**- Revocation Mechanisms:**
Revoking access granted through OAuth requires coordination with the third-party provider, potentially introducing delays or complexities.
**- Limited Control:**
The level of control you have over user data obtained through OAuth depends on the provider's policies and APIs.
``` php
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Laravel\Socialite\Facades\Socialite;
use App\Models\User;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
class OAuthController extends Controller
{
// Redirect the user to the OAuth Provider
public function redirectToProvider($provider)
{
return Socialite::driver($provider)->redirect();
}
// Obtain the user information from the provider
public function handleProviderCallback($provider)
{
$user = Socialite::driver($provider)->user();
// Check if the user already exists in the database
$existingUser = User::where('email', $user->getEmail())->first();
if ($existingUser) {
// Log the user in
Auth::login($existingUser);
} else {
// Create a new user
$newUser = User::create([
'name' => $user->getName(),
'email' => $user->getEmail(),
'password' => Hash::make(uniqid()), // Generate a random password
'provider' => $provider,
'provider_id' => $user->getId(),
]);
Auth::login($newUser);
}
// Redirect to the intended page
return redirect()->intended('/home');
}
}
// In routes/web.php
use App\Http\Controllers\Auth\OAuthController;
Route::get('login/{provider}', [OAuthController::class, 'redirectToProvider']);
Route::get('login/{provider}/callback', [OAuthController::class, 'handleProviderCallback']);
// In config/services.php
return [
// Other services...
'github' => [
'client_id' => env('GITHUB_CLIENT_ID'),
'client_secret' => env('GITHUB_CLIENT_SECRET'),
'redirect' => env('GITHUB_REDIRECT_URI'),
],
'google' => [
'client_id' => env('GOOGLE_CLIENT_ID'),
'client_secret' => env('GOOGLE_CLIENT_SECRET'),
'redirect' => env('GOOGLE_REDIRECT_URI'),
],
// Add other providers as needed...
];
// In .env file
GITHUB_CLIENT_ID=your-github-client-id
GITHUB_CLIENT_SECRET=your-github-client-secret
GITHUB_REDIRECT_URI=http://your-callback-url
GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-client-secret
GOOGLE_REDIRECT_URI=http://your-callback-url
// Add other provider credentials as needed...
```
## Choosing Your Champion: A Comparative Analysis
Now that we've explored the strengths and weaknesses of each approach, let's delve into a comparative analysis to guide your decision-making process:
**_Remember:_** The optimal authentication strategy hinges on your project's specific requirements. Consider these factors:
_**1. Application Type:**_
Web application, API, Mobile App, etc.
_**2. Scalability Needs:**_
Expected number of users and potential for growth.

Esse caminho de criação de módulos, abre novas possibilidades para a rápida disponibilização de soluções baseadas em pacotes Go.
Neste artigo, veremos como utilizar o XK6 para desenvolver um novo módulo, baseado em uma solução em Go.
## Pré-requisitos📑
- [K6 instalado](https://k6.io/docs/get-started/installation/)
- [Go instalado](https://go.dev/)
- [XK6 instalado](https://github.com/grafana/xk6)
## O problema👥
Para quem conduz testes no contexto brasileiro, é notavel que informações como CPF e CNPJ desempenham um papel crucial nos cenários de negócios de muitas aplicações.
Atualmente, o K6 não oferece um módulo que permita a geração de [CPF](https://pt.wikipedia.org/wiki/Cadastro_de_Pessoas_F%C3%ADsicas) para uso em scripts de teste de performance, o que restringe as opções de implementação de alguns scripts que necessitem de grandes volumes dessa massa.
A ausência desse recurso deixa os usuários sem alternativas além de recorrer a módulos Javascript, que podem apresentar desempenho inferior quando incorporados a scripts no K6.
Ao analisar as soluções disponíveis em Go, percebemos que a comunidade brasileira disponibiliza diversos pacotes para a geração e validação de CPF e CNPJ. Um exemplo notável é a biblioteca [go-cpf](https://github.com/mvrilo/go-cpf), que oferece a possibilidade de geração de CPF com e sem mascara de formatação.
## Criando um modulo XK6📚
Em um diretorio de sua preferencia, utilize o comando `go mod init xk6-cpf` para iniciar um novo modulo Go. Caso o modulo seja iniciado com sucesso, na raiz do seu diretorio, será criado um arquivo `go.mod` que registra as dependências do seu projeto, incluindo os módulos que você importa e suas versões.
> Neste exemplo, nosso modulo foi iniciado em um diretorio de nome xk6-cpf.
No mesmo diretorio onde nosso modulo foi iniciado, vamos criar um arquivo de nome `cpf.go`, utilizaremos esse arquivo para realizar toda a configuração do nosso modulo.
Inicialmente vamos definir o nome do nosso pacote Go, para que ele possa ser utilizado por outros arquivos Go, bem como para ser usado em scripts Javascript com o k6.
```
package cpf
```
Em seguida, vamos importar os pacotes necessários para o nosso módulo. O pacote `go-cpf` fornece funcionalidades para a criação de CPFs com e sem máscara. Já o pacote `k6/js/modules` é utilizado para registrar módulos personalizados, permitindo seu uso em scripts Javascript com o k6.
```
import (
"github.com/mvrilo/go-cpf"
"go.k6.io/k6/js/modules"
)
```
Um dos pontos importantes quando falamos em utilizar modulos XK6, é o registro do nosso modulo. Vamos utilizar a função especial `init()` do Go, para registramos o modulo `xk6-cpf` como `k6/x/cpf`, utilizando a função `Register` do pacote `k6/js/modules`:
```
func init() {
modules.Register("k6/x/cpf", new(CPF))
}
```
> Essa nomenclatura é utilizada para que o módulo possa ser importado no script de teste de performance, com uma sintaxe semelhante à seguinte: import cpf from 'k6/x/cpf'
Vamos definir uma estrutura do tipo CPF, que conterá as funções disponíveis para uso no Javascript.
```
type CPF struct{}
```
Precisamos criar uma função do tipo `CPF` que receba um argumento booleano. Esse argumento será usado para definir se o usuário deseja um CPF formatado ou não. A função de geração do nosso módulo será a seguinte:
```
func (*CPF) Cpf(formatado bool) string {
if formatado {
return cpf.GeneratePretty()
}
return cpf.Generate()
}
```
Ao final, nosso arquivo cpf.go terá a seguinte estrutura:
```
package cpf
import (
"github.com/mvrilo/go-cpf"
"go.k6.io/k6/js/modules"
)
func init() {
modules.Register("k6/x/cpf", new(CPF))
}
type CPF struct{}
func (*CPF) Cpf(formatado bool) string {
if formatado {
return cpf.GeneratePretty()
}
return cpf.Generate()
}
```
Para gerar uma versão do binário do k6 que contenha o módulo que acabamos de construir, podemos utilizar o seguinte comando xk6:
```
xk6 build --with xk6-cpf=.
```
## Utilizando o modulo xk6-cpf👩💻
Para utilizar o módulo que acabamos de criar, podemos importá-lo em nosso script conforme definido no modules.Register. Na fase de inicialização, importamos nosso módulo xk6 com o seguinte comando:
```
import cpf from 'k6/x/cpf';
import { sleep } from 'k6';
```
Na fase de configuração, vamos definir uma carga para observar a geração de CPFs utilizando nosso módulo xk6:
```
export const options = {
vus: 1,
duration: '3s',
}
```
Na fase de execução, podemos utilizar a função Cpf do módulo XK6 para verificar a geração de CPFs válidos para uso em nosso script.
```
export default function () {
console.log(`Gerando um novo CPF: ${cpf.cpf(false)}`);
sleep(0.5);
}
```
> O argumento _**false**_ informando na função cpf indica que queremos um cpf sem mascara de formatação.
Para executar nosso script, podemos utilizar o comando `.\k6.exe run teste.js`, podemos observar o resultado de saida:
```

## Utilizando um modulo remoto☁️
No exemplo anterior, o nosso módulo XK6 foi gerado localmente. Uma alternativa de utilização é disponibilizar um módulo remoto para uso.
Para isso, na sua ferramenta de linha de comando, utilize o seguinte comando:
```
xk6 build --with github.com/marlo2222/xk6-cpf
```
Utilizando o script anteriomente contruido, podemos utilizar o seguinte comando para execução:
```
.\k6.exe run teste.js
```
E como resultado de saida teremos:
```

With this number increasing rapidly among companies at all levels, organizations are looking forward to the methods that help them:
- Eliminate platform complexities
- Reduce information leakage
- Minimize cloud operation costs
To materialize these elements, organizations are actively turning to DevOps culture that helps them integrate development and operations processes to automate and optimize the complete software development lifecycle.
In this blog post, we will discuss the step-by-step approach to cloud migration with DevOps.
## Steps to Perform Cloud Migration With DevOps Approach
Automation, teamwork, and ongoing feedback are all facilitated by the DevOps culture in the cloud migration process.
This translates into cloud environments that are continuously optimized to support your business goals and enable faster, more seamless migrations with reduced risks.
The following procedures outline how to migrate to the cloud while utilizing **_[DevOps principles](https://opstree.com/services/)_**:
## 1. Understanding Objectives and Infrastructure Assessment
First and foremost, define your cloud migration goals. Workshops and meetings with team members/stakeholders will help describe and document the goals.
Make an inventory of all the workloads, dependencies, and applications that are currently in use to analyze your current infrastructure and applications.
To visualize relationships and spot possible migration problems, use tools like Application Dependency Mapping and Decision Matrix. Examine the differences in applications between rebuilding, replacing, refactoring, rearchitecting, and rehosting.
Form a cross-functional team with members from development, operations, QA, and security. Assign roles and duties to make sure that everyone is aware of their responsibilities during the migration process.
## 2.Design and Planning
Build solid infrastructure using Infrastructure as a Code (IaC) tools like Terraform or AWS CloudFormation after the initial assessment stage. This makes managing cloud resources simple and guarantees consistency. Version control systems such as Git can improve collaboration and make tracking and rollback of changes easier.
BuildPiper, Jenkins, or Azure DevOps-powered **_[CI/CD pipelines](https://www.buildpiper.io/ci-cd-pipelines/)_** can automate important tasks, providing the foundation for a seamless migration process. To avoid vulnerabilities and guarantee compliance, incorporate security measures at an early stage and securely manage secrets using AWS Secrets Manager or HashiCorp Vault.
## 3.Migration Preparation
When planning to migrate to the cloud, one must be prepared for large-scale data transfers. This can create many business risks that are easily mitigated when there is a good migration plan.
Below are some ways you can prepare your migration plan in line with DevOps principles:
**Automation**: Set up CI/CD pipelines using tools like BuildPiper, Jenkins, and Azure DevOps. These pipelines automate such critical tasks as application building, testing, and launching hence giving your team more time to focus on strategic initiatives and ensuring consistent deployments through the entire process of migration.
**Continuous Validation**: Include automatic checks in your CI/CD pipelines so that you can continuously verify every code change that has been made thus reducing the likelihood of introducing defects or producing regressions during the transition.
**Early Security Measures**: Incorporate security scanning products like Snyk or SonarQube into your CI/CD pipelines. Such tools check for possible security weaknesses in your code already at the development stage thus preventing them from becoming exploitable threats in a cloud environment.
**Backup and Disaster Recovery**: Come up with a comprehensive backup and DR (disaster recovery) plan. Choose either a cloud-based backup solution or a third-party tool and set clear procedures on how to restore data and applications after disasters occur. Regularly test the solutions you have put in place
## 4.Execute Migration
Migrate to the cloud in stages, which is a prudent way to handle any unforeseen issues and adapt the needed changes to remain stable through this process. This will help support your operations to remain stable as you proceed with the migration. To find out, begin with noncritical applications. It will help you adjust your strategy as needed without the risk of disrupting important services, which makes the migration rather smooth on the whole.
CI/CD pipelines need to be maintained to ease the management of the migration. Techniques like canary or blue-green deployments allow incremental changes, so you can nip issues in the bud before they snowball to become system-wide problems. This further sectioned approach will keep you in control and reduce the possibility of huge interruptions.
Automated testing should be key to any successful migration. The Jenkins or GitLab CI tool is useful to help one run all types of tests to make sure that applications will run fine in a new environment. Finding them early means an early resolution before they balloon into problems, thus retaining a high performance and **_[security standard](https://www.buildpiper.io/managed-security-observability/)_**.
Use Infrastructure as Code tools, such as Terraform and AWS CloudFormation, so that you can track the changes made in your infrastructure. This helps manage changes in the infrastructure in a repeatable, traceable, and reversible way, hence conforming with DevOps principles. This way, if anything goes wrong, it’s easy to roll back to previous states, meaning less downtime and a smooth transition.
Prometheus with Grafana, or AWS CloudWatch, is what is important at this stage of migration for monitoring and observing the system’s health. They help to keep an eye on system health with real-time insights and alerts and support you in a proactive way of remediation to keep the system stable.
Then, detailed rollback procedures should be in place; it can be managed with version control, hence ensuring quick recovery in the occurrence of any issue. On top of that, all the previous configurations within the CI/CD pipeline make a rollback to a stable state easy and at the same time give assurance of its reliable and resilient migration.
## 5.Post-Migration Activities
To move to the cloud, make sure that your configuration is well maintained and not more expensive than necessary. This can be enabled by embracing DevOps principles. In conclusion, it is important to examine how you are using your assets for better performance and cost reduction.
These tools dynamically regulate resources so that optimal resource efficiency is realized and assume changes in offerings that might be needed over time. Other tools like Prometheus or AWS CloudWatch help isolate trouble spots so they can be identified.
With continuous integration (CI) and continuous delivery (CD), regular checks as well as feedback enable making seamless transitions between the two systems keeping your environment contemporary and fully operational. Therefore, there should be a record of setting up things and also the knowledge on how to keep them running smoothly for years that lie ahead. After all, this manner of operation suitably aligns with DevOps principles of continuously learning and improving thereby ensuring long-term success in one’s cloud setup.
Continuous DevOps Practices for **_[Cloud Migration](https://dev.to/anshul_kichara/optimizing-cloud-spending-the-synergy-of-devops-and-finops-4632)_**
An extremely important aspect not to overlook is having a robust DevOps culture post-migration. Here are some major practices that will ensure continued improvement and efficiency:

تقدم Dzrt مجموعة من النكهات الكلاسيكية، ولكل منها لمسة رقمية فريدة. فكر في آيس كريم الفانيليا مع طبقة ثلاثية الأبعاد أو كعكة الجبن التقليدية مع العناصر التفاعلية.
النكهات التجريبية والغريبة
بالنسبة للمغامرين، يستكشف Dzrt أيضًا النكهات التجريبية والغريبة. يتضمن ذلك مجموعات لا تجدها عادةً في الحلوى التقليدية، مثل موس الماتشا واللافندر أو كمأة الشوكولاتة المملوءة بالفلفل الحار.
كيف يتم صنع Dzrt
المكونات المستخدمة
تستخدم Dzrt مكونات عالية الجودة للتأكد من أن المذاق يتناسب مع المظهر البصري. من الفواكه العضوية إلى الشوكولاتة اللذيذة، يتم اختيار كل مكون بعناية.

مجالات التحسين
في حين أن ردود الفعل إيجابية إلى حد كبير، يشعر بعض العملاء أن التكنولوجيا يمكن أن تكون أكثر سهولة في الاستخدام، خاصة بالنسبة لأولئك الذين ليسوا على دراية بالتكنولوجيا. بالإضافة إلى ذلك، فإن نقطة السعر، على الرغم من تبريرها بالجودة والابتكار، يمكن أن تشكل عائقًا بالنسبة للبعض.

التحديات التي تواجه دزرت
القيود التكنولوجية
في حين أن Dzrt هي في طليعة الابتكار، إلا أنها تواجه تحديات تتعلق بالقيود التكنولوجية. إن ضمان إمكانية الوصول إلى التكنولوجيا وسهولة استخدامها لجميع العملاء هو جهد مستمر.
المنافسة في السوق
مع نمو سوق الحلويات الرقمية، تنمو المنافسة أيضًا. تحتاج Dzrt إلى الابتكار والتكيف باستمرار للبقاء في صدارة المنافسين الذين يستكشفون أيضًا مجال الغذاء الرقمي.
عالم Dzrt هو مزيج مثير من التكنولوجيا وفنون الطهي. عندما نتطلع إلى المستقبل، فمن الواضح أن Dzrt لديها القدرة على إحداث ثورة في طريقة تفكيرنا في الحلويات. سواء كنت منجذبًا إلى تصميماتها المبتكرة، أو عناصرها التفاعلية، أو نكهاتها القابلة للتخصيص، فإن Dzrt تقدم شيئًا للجميع. احتضن مستقبل الطعام مع Dzrt واستمتع بتجربة حلوى لا مثيل لها.

Today I want to share a candid reflection on my journey with some of the most transformative tools in the web development world: Laravel, PestPHP, Livewire and Vue.js.
## Laravel
From the moment I started using Laravel, I knew it was more than just a framework; it was a real game changer! Laravel's elegant syntax and powerful features made backend development a pleasure. It feels like Laravel understands what developers need, providing solutions before we even realize we need them. Every time I embark on a new project, Laravel proves to be the reliable backbone, offering stability and flexibility.
[Laravel](https://laravel.com/)
## PestPHP
Testing was previously a significant challenge for me until I discovered PestPHP. Its simplicity and expressive syntax transformed a tedious task into a valuable and efficient part of the development process. With PestPHP, ensuring the reliability of my code has never been easier or more efficient. It provides a safety net that catches bugs before they become problems, allowing me to concentrate on building and innovating. To learn more about how PestPHP can enhance your testing experience, please refer to my blog posts.
[PestPhp](https://pestphp.com/)
## Livewire
Livewire has revolutionized my approach to front-end development. The ability to create responsive and dynamic interfaces without writing JavaScript was a significant improvement. Livewire integrates seamlessly with Laravel, making the development process more efficient and intuitive. It's as if I had a superpower that allows me to build complex interactions effortlessly, while remaining within the comfort zone of PHP.
[Livewire](https://livewire.laravel.com/)
## Vue.js
Vue.js has consistently been my preferred choice for creating user interfaces that are both beautiful and responsive. Its component-based architecture and responsive data binding make it an enjoyable and productive tool to use. Vue.js allows me to create engaging, interactive experiences that users love. Every project feels like a canvas, with Vue.js providing the tools to bring my visions to life.
[VueJs](https://vuejs.org/)
## Conclusion
As I continue on this exciting journey, I am continually impressed by the possibilities these technologies open up. They have not only enhanced my skills, but also reignited my passion for web development. Every project presents an opportunity to learn, grow and create something extraordinary.
Thank you for joining me on this journey. I look forward to sharing more insights and experiences with you. Let's continue to embrace the future of web development together!

The story of software development companies in the US dates back to the mid-20th century, starting with the rise of computers. Early pioneers like IBM and Microsoft laid the groundwork by creating essential software such as operating systems and business applications. The 1990s brought the internet boom, giving rise to now-household names like Google and Amazon. These companies expanded the scope of software, introducing web services and revolutionizing e-commerce.

Staying competitive in a fast-paced market demands continuous innovation. Moreover, there's a notable shortage of skilled professionals, emphasizing the need for better education and training programs.
Looking ahead, the future seems bright. Emerging technologies like artificial intelligence, machine learning, and quantum computing promise to drive the next wave of innovation. Companies will likely focus on creating smarter, more efficient, and secure software solutions to meet the demands of an increasingly digital world.

Software development companies in the US have been key players in the technology revolution. Their innovations have transformed industries, boosted the economy, and improved our quality of life. As they tackle challenges and explore new technological frontiers, these companies will continue to shape the future of technology. The journey of software development in the US is a testament to the nation's spirit of innovation and entrepreneurship, promising a future filled with groundbreaking advancements and endless possibilities.

Here’s a comprehensive guide to promoting digital marketing services, particularly if you’re offering these services in a competitive market like Delhi.
Understand Your Target Audience
Before promoting your digital marketing services, it’s essential to understand who your target audience is. Are you targeting small businesses, large corporations, startups, or specific industries? Knowing your audience helps in tailoring your marketing message to meet their specific needs and challenges.
Optimize Your Website for SEO
Your website is often the first point of contact for potential clients. Ensure it is optimized for search engines to attract organic traffic. Focus on local SEO by including keywords such as “digital marketing services in Delhi”, “**[digital marketing company in Delhi](https://www.creationinfoways.com/digital-marketing-services.html)**”, and “digital marketing agency in Delhi”. Create high-quality content that addresses the needs of your target audience and includes these keywords naturally. Also, make sure your website is mobile-friendly and has a fast loading speed.

Social media is a powerful tool for promoting digital marketing services. Utilize platforms like Facebook, LinkedIn, Instagram, and Twitter to reach a broader audience. Share valuable content such as blog posts, case studies, client testimonials, and success stories. Engage with your audience by responding to comments and messages promptly.

1,886,856 | Git: How to fix PR conflicts | When working with PRs, we may encounter conflicts trying to merge them. In this article, we will... | 27,621 | 2024-06-13T11:14:21 | https://henriqueleite42.hashnode.dev/git-how-to-fix-pr-conflicts | git, webdev, beginners, programming | When working with PRs, we may encounter conflicts trying to merge them. In this article, we will learn what conflicts are and how to fix them.
## What causes conflicts
In the image above, you can see that we have a main branch called `master`, and from this branch we created 2 new branches at the same *point in time*: `feat/1` and `feat/2`.
**Obs:** *point in time* is not the same as *time*. *Point in time* means that no changes happened in the branch since the last time you checked. On the example above, the `master` branch keeps on the same `point in time` until the `PR #1` is merged and the state of the branch changes.
After we created both branches (one can be created by you, and another one by your coworker), we start to make changes on them to develop a new feature, fix a bug, or improve the documentation, anything that we want to change.
As things on each branch are different, one of them will probably be faster to develop and will have the PR merged first, and once in a while may happen that 2 branches must change the same file.
As both branches were created at the same *point in time*, git will not be able to know which one of the changes it must keep, the one of `PR #1` or the one of `PR #2` (your PR), and it will cause the conflict.
## How to fix the conflict
If the git commands below don't work, it may be because you need to [configure your git](https://henriqueleite42.hashnode.dev/git-how-to-boost-your-performance) before executing them.
* Go back to the `master` branch (or the source branch for your current branch)
* `git checkout master`
* Get the updated state
* `git pull`
* Go back to your branch
* `git checkout feat/2`
* [Rebase](https://git-scm.com/book/en/v2/Git-Branching-Rebasing) with master
* `git rebase master`
* See the files that are causing conflicts
* `git status`
* Go to the files and make the necessary change to the file to include both your changes and the previous changes.
* Add the files to be tracked by git
* `git add .`
* Continue the rebase
* `git rebase --continue`
* \[May not occur\] If a strange text appears, run the commands:
* If you are using `vim`, press `Esc`, `:wq` and `Enter`
* If you are using Ubuntu's default editor, press `Ctrl + O`, `Enter` and `Ctrl + X`
* Push the changes
* `git push`
## Conclusion
And that's it! Solving conflicts is not the end of the world, we can fix them very quickly. Hope that this article helped you in some way, and if you have anything to say or an experience to share, please say it in the comments! 😄 | henriqueleite42 |

tags: Elestio, N8N, API
canonical_url: https://blog.elest.io/n8n-retrieves-weather-information-based-on-a-zip-code/
cover_image: https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2ac07yo7jg9y0sv75eb1.png
---
Hey everyone, In this blog we are going to see how you can create an application that can retrieve weather information based on a zip code using API. During this tutorial, we will be creating the workflow using a template. You can create the same from scratch too. Before we start, make sure you have deployed N8N, we will be self-hosting it on [Elestio](https://elest.io/open-source/n8n?ref=blog.elest.io).
## What is N8N?
N8N is an open source workflow automation tool that allows you to automate tasks and workflows by connecting various applications, services, and APIs together. It provides a visual interface where users can create workflows using a node-based system, similar to flowcharts, without needing to write any code. You can integrate n8n with a wide range of applications and services, including popular ones like Google Drive, Slack, GitHub, and more. This flexibility enables users to automate a variety of tasks, such as data synchronization, notifications, data processing, and more.
## Using Template
Once you log in to N8N you will land on the canvas page of N8N. To check out different templates and use one, head over to the templates section from the left sidebar.
Then search for "Receive the weather information of any city" template or simply click [here](https://n8n.io/workflows/807-receive-the-weather-information-of-any-city/?ref=blog.elest.io). Next, click on **Use workflow**.
Select the N8N instance you want to use this template for. If you have multiple N8N instances running then you can choose the appropriate one.
## Configuring OpenWeatherMap Credential
Now as you move ahead in the process you will be prompted with pop up to configure OpenWeatherMap credentials. Click on **Create new OpenWatherMap credential**.
Now if you don't have OpenWeatherApp account then follow these steps before heading further. Feel free to skip these if you already have an account and API Key.
Head over to [OpenWeatherApp Website](https://openweathermap.org/?ref=blog.elest.io) and create a new account. Add **Username** , **Email, Password** to create your account.
Next provide our Company/Organisation and purpose and click **Save**.
Head over to the **API Keys** and add **API key name** and click on **Generate** to generate an API Key. Copy the **Key** that will be used in the further steps.
Paste the previously copied key in the **Access Token** section and click on **Save.**
## Creating Workflow
Once you are redirected back to the workflow screen you will find components like below. To start with click on the first **Webhook** component. In this component we set up the endpoint URL, authentication mechanism etc for API endpoint to be hit to get the result we desire.
Once you click on **Webhook** you can copy **Test URL/Production URL** , Select the HTTP Method. Here we are trying to make a **GET** request so we have selected it from the drop down menu. Let's keep Authentication as none for the simplicity but make sure while in production you add the authentication to provide security to the endpoints. Additionally we will configure the response to be made **When Last Node Finishes** under **Respond**.
Following part of workflow enables you to make API request to **OpenWeatherMap** and get response from it. It takes input from the previous webhooks such as city name or zip code. Click on section to setup the requests.
Here we will select the credentials created in our previous steps. Select the settings as following
**Operation:** Current Weather
**Format:** Metric
**Location Selection:** City Name
**City:** `{{$node["Webhook"].json["query"]["city]}}`
**Language:** en
Next we will configure the **Set** component. Click on this component as shown in the following images and move to the configuration part.
Set the **Values to Set** as
**Name:** temp
**Value:** `{{$node["OpenWeatherMap"].json["main"]["temp"]}}`
**Name:** description
**Value:** `{{$node["OpenWeatherMap"].json["weather"][0]["description"]}}`
## Testing Workflow
For testing your workflow you will see **Test workflow** button. Click on it and paste the endpoint URL copied from the **Webhook** component in the earlier steps. Make sure you add the query property to it. In this case it will be `?city=10019` so the final url will look something like
```
https://n8n-wgahh-u7774.vm.elestio.app/webhook-test/45690b6a-2b01-472d-8839-5e83a74858e5?city=10019
```
And you should see output like below.
And done! You have successfully created application that will make API request to retrieve weather location based on zip code. You can form multiple such workflows based on the request type.
## **Thanks for reading ❤️**

1,863,360 | The Adventures of Blink #27: LLMs in Code | So last week was pretty wild, huh? Our previous adventure saw us download GPT4all and add in some... | 26,964 | 2024-06-13T11:00:00 | https://dev.to/linkbenjamin/the-adventures-of-blink-27-llms-in-code-1mda | ai, python, beginners, llm | So last week was pretty wild, huh? Our [previous adventure]() saw us download GPT4all and add in some local data, which gave me the ability to have a conversation with my memoirs!
## The UI has limited usefulness
GPT4All's application is a _fantastic_ sandbox for ideas. We can start to load data and models and experiment to see how they interact. While being able to do that in the GPT4All interface was wicked cool, let's be real: this is a developer blog. Code needs to be written here! Besides... the real compelling thing about this AI revolution is what happens when models and data are able to interact "in the wild"... when we can start to use their unique capabilities by embedding them in other software.
> _Note: This is why Gemini and ChatGPT sandboxes are free-to-play. You might be wondering how they can afford to serve up so many requests... it's because the API calls are where the **real** money is!_
## Uh... so, where do we start?
This question confounded me for quite a while. I don't know if I was just obtuse, or if the documentation needs to be improved, or _what_... but I simply couldn't figure out where to get started with coding things that used LLMs! And that, my friends, is what I'm going to do today - let's learn how to connect a python program to a LLM!
## Finding the model
Fortunately, GPT4All makes it pretty easy to do this! We can start in the [official docs](https://docs.gpt4all.io/index.html). Here on the front page you can see the simplest python app you can write to connect to a language model, some 4 lines:
```python
from gpt4all import GPT4All
model = GPT4All("orca-mini-3b-gguf2-q4_0.gguf")
output = model.generate("The capital of France is ", max_tokens=3)
print(output)
```
It's admittedly very crude - it's sort of the "hello world" of LLMs - but technically, that's enough to get started! We'll of course need to `pip install gpt4all` before we run our program... but then the model will respond with its guess as to the identity of France's capital.
## Let's move on to the next step and have a conversation
Having a hard-coded question that generates a short response is kinda boring. It could be interesting if you were still trying to learn Python, perhaps, but wouldn't it be better if we could have a loop of some kind that gave us a conversation?
You can see details on building this in the [quickstart](https://docs.gpt4all.io/gpt4all_python.html#chatting-with-gpt4all). We just need to instantiate a `model.chat_session()`! This provides a looping kind of structure where we're now able to interact with the model repeatedly.
## TL/DR: YouTube
Not a reader? Just click here and you can watch me build the same thing!
{% embed https://www.youtube.com/watch?v=NTStlevKmtw %}
> Note: I don't cover the vocabulary check below in the video, just the build...
## A Quick Vocabulary Check
If this is your first time in LLM documentation, you've probably run across some words that didn't make sense. You might be able to infer their meaning from context, but instead of assuming you figured it all out, here's a handy list:
### Embedding
An Embedding is a sort of "knowledge nugget" for a model. Embeddings are when you take some input text and run it through the model to create a Vector. LLMs work by being able to find Embeddings that are "near" each other in space - that distance between two Vector Embeddings is a measure of how closely related the two tokens are. Using probabilities and measurements of these vector relationships is how an LLM can generate sentences that sound "normal" to humans... by predicting what words are likely to come next in the flow of thought.
### Generation
This is the ability of the model to create an appropriate response to an input. This requires you to have a LLM and an input, nothing else. You're at the mercy of whatever the model was trained on - so if they built it with the works of William Shakespeare, you're not going to find any Emily Bronté in there!
### Model
A Model is a machine-learning algorithm that's been trained on a large data set, to establish a base of data to evaluate your tokens against. These vary in size and complexity; and the data science folks are regularly training new models with increasing efficiency and skill to create smarter and smarter AI tools! A model is limited in knowledge to the data set that it was trained with - for example, you couldn't train a model with wikipedia articles and expect it to be a good surgeon's assistant!
### RAG
RAG (Retrieval-Augmented Generation) is an architecture that allows you to "enhance" a model with embeddings of a specific dataset. For instance, if you wanted to download all of your company's policies and procedure manuals and documentation, you could enhance a generic LLM like Llama3 with this dataset to create a "smart assistant" who would know about your business practices and be able to help with something like customer support or HR questions. In RAG architecture you have a base model, a set of embeddings of your dataset, and some code that ties them together and uses the model's Generation capabilities to interact with the data set's embeddings.
### Token
A Token is the smallest chunk of data that an LLM can work with. It's kinda analogous to a word (but not exactly, sometimes it could be a couple words, or maybe just a few characters). Tokens are used to measure the complexity of a query (and therefore used to measure how much it costs you as a consumer to make a given API call).
### Vector
Just like in math & physics classes, this is a multi-dimensional array of values. Every nugget of input that a model is trained on becomes a special Vector called an Embedding.
## Back to building
So... a simple python program that creates a conversation loop would look like the following:
```python
# Importing GPT4All and picking the orca model.
from gpt4all import GPT4All
model = GPT4All('orca-mini-3b-gguf2-q4_0.gguf', allow_download=False)
# The system prompt provides instructions to the model about how to
# respond. You can change this to your preferences.
system_prompt = '### System:\nYou are my personal AI assistant. You follow my instructions carefully and try to provide me with the most accurate information.\n\n'
# The prompt template helps the model understand the format of the
# data it's going to parse. This helps the model understand the flow
# of the conversation - you could theoretically set a delimiter here
# and it would keep processing until it found it.
prompt_template = '### User:\n{0}\n\n### Response:\n'
# Now we're ready to actually do something. We create a chat_session

with model.chat_session(system_prompt=system_prompt, prompt_template=prompt_template):
# infinite loop that's cleared when the user types 'quit'
while True:
user_input = input("User:")
if 'quit' in user_input.lower():
break
else:

print(f"\n\n{model.generate(user_input)}\n\n")
```
Impressively short code, isn't it? If I remove the comments, it's like 11 lines... to create an ongoing chat with a Large Language Model!
## That's a wrap... for today 😉
While that's a super cool project to get started with, next week we're going to see if we can kick things up a notch. See, this LLM conversation is limited to the model's data. Just like we talked about in [last week's Adventure](https://dev.to/linkbenjamin/the-adventures-of-blink-26-gpt4all-and-all4gpt-2hdp?preview=4e026e19af5580771bd2f83dc099a39e692c7c780ccb0227005d258864fedac675dee0520d9397567f9b86109d494ce60dc3e0dc95bc4969a8b3cf0b), we'd like to use our own data set alongside the LLM as a **Retrieval Augmented Generation (RAG)** application. This allows us to "train" our bot to handle specific information expertly... data that wasn't part of the model's original training. So tune in next week as we expand on this concept to create our very own **Retrieval Augmented Generation (RAG)** app!

Alongside existing... | 0 | 2024-06-13T10:53:30 | https://devot.team/blog/web-application-security-best-practices | database, privacy, security | Security is a major threat to companies striving to deliver software quickly. Alongside existing vulnerabilities in application code and security breaches, companies and developers must also be aware of the potential security vulnerabilities that super-powerful quantum computers pose to currently used cryptographies.
To raise awareness of security risks, it is crucial to be informed about new threats to IT security.
The problems vary: encrypted data can be stolen, stored for potential decryption by quantum computers in the future, and so on. To ensure the protection of sensitive data, developers must prioritize the implementation of modern secure programming practices and strong encryption and authentication into applications.
**Be aware of the data leakage**
Perhaps we can live with the fact that our data is used without our consent, but none of us likes it when this data ‘leaks’ into the public domain on the internet without our consent or knowledge.
Although many companies maintain high-security standards and invest large amounts of money in protecting their users' data, data leakage is still a common problem. As internet users, we all have private data stored on various websites and applications. Therefore, it is important to be aware of the dangers of data leakage and always check the security of the websites and applications we use.
**OWASP Top 10 most critical vulnerabilities**
To protect themselves from attacks, companies should follow recommendations and best practices in web security.
The Open Worldwide Application Security Project (OWASP) is a nonprofit organization dedicated to improving software security. Among many projects, OWASP also works on documents like the “OWASP Top 10 Most Critical Vulnerabilities,” which consist of a broad consensus on the biggest security risks for web applications.
The goal of this document is to raise awareness among developers and other IT industry professionals about the greatest security risks and educate them on how to prevent these risks. In this blog, we will highlight the five most critical vulnerabilities from the mentioned top 10:
**1. A01:2021 - Broken access control**
94% of applications were tested for some form of improper access control, showing that 34 common weaknesses of improper access control appeared more frequently in applications than any other category.
**2. A02:2021 - Cryptographic failures**
previously known as sensitive data exposure, which was a general symptom, not a primary cause. The renewed focus here is on flaws related to cryptography that often lead to the exposure of sensitive data or compromise the security of systems.
**3. A03:2021 - Injection**
94% of applications were tested for some form of injection, and the 33 CWEs categorized here rank second in the frequency of occurrence in applications. Cross-site scripting is now also included in this category.
**4. A04:2021 - Insecure design**
a new category focusing on risks associated with design flaws. If, as an industry, we truly want to make a shift towards security, this requires greater use of threat modeling, secure design patterns, principles, and reference architectures.
**5. A05:2021 - Security misconfiguration**
90% of applications were tested for some form of incorrect security configuration. With the increase in transition to highly configurable software, it is not surprising to see this category progressing. The former category for XML External Entities (XXE) is now part of this category.
**Broken access control**
Access control implements measures that prevent users from acting beyond granted permissions. Deficiencies usually lead to unauthorized disclosure, alteration, or destruction of data or performing some business function outside of user limitations.
- Common vulnerabilities in access control include:
- Unauthorized access to specific features or users
- Circumventing access control checks by changing URLs
- Allowing the viewing or editing of someone else’s account by exposing a unique reference to objects
- API security with missing access controls
- Incorrect CORS configuration that allows access to the API from unauthorized or untrusted sources (i.e., lack of whitelisting)
Implementing security tests into unit tests is a long-term investment that involves greater investment in developers' awareness of security. In addition to helping developers better understand how to test for security issues, this can greatly improve the overall quality of software and reduce the number of vulnerabilities in web applications.
**Cryptographic weaknesses**
Do we ensure security using protected HTTPS protocols when transferring information? Websites secured with HTTPS connections provide visitors with enhanced reliability through data encryption, which makes it more difficult to track users and their data.
In addition to tracking users, the content received is also secured because it involves a secure communication channel where interception and modification of the received content are prevented. Some internet browsers, such as Google Chrome, penalize and specifically mark websites that are unprotected by SSL/TLS certificates (used for HTTPS protocols).
We secure files when transferring them between users using the FTPS protocol. Originally, the FTP protocol allowed users to transfer files without any encryption or protective measures. FTPS is an upgraded FTP with an added security level of Secure Socket Layer (SSL).
Similarly, as with HTTPS protocols, a secure communication channel is established through which all information passes between the user and the website. All data are encrypted, and only an SSL-protected server can decrypt these data using a shared SSL key.
**SQL injection**
A security problem that has existed for over 20 years. Why is it still present in 2024?
SQL injection attacks occur when attackers send invalid data to an application, which is mistakenly executed as SQL commands. This can manipulate the database data without proper authorization. Attackers insert SQL commands where they are not expected, for example, in the password input field during application login.
What are some methods to protect against SQL injection attacks?
**1. Data sanitization of user input**
The application should ensure the elimination of all characters from user input that could be executed as SQL code, such as parentheses and colons.
**2. Input validation**
The application should ensure input validation and limit the number and type of characters that can be entered.
**3. Use of a secure API interface**
The recommended option is to use a secure API interface that completely avoids using an interpreter, provides a parameterized interface, or uses tools for object-relational mapping (ORM).
The reasons behind security issues in 2024
So, going back to the previous question, do these security issues still exist in 2024?
Lack of specific security awareness among developers
There's often a shortfall in security-specific awareness and training among those who develop applications.
Lack of automated effective testing methods
There is a lack of automated testing methods that enable precise detection of injections (e.g., tests without false positive results).
Use of database access libraries
These libraries are supposed to provide a secure way to access databases but can often still be exploited, giving developers a false sense of security.
Volume of SQL databases
Finally, almost every web application uses some form of database, and the sheer volume of SQL databases on the internet provides a broad surface for attack.
**How things have changed - From experts to users**
It is certainly necessary to follow recommendations and best practices in web security, such as those suggested by OWASP.
However, even though recommendations and security tools are available, attackers often exploit vulnerabilities that also appear in the libraries we use in application development. Previously, we had to manually program everything because there weren't as many auxiliary libraries as available today.
On the other hand, those that did exist often did not meet the needs of our applications. Therefore, developers had to have a broad knowledge of program functionalities without the help of additional libraries.
Since we could not rely too much on ready-made solutions, most developers paid more attention to security. However, over time we began to use libraries for almost everything, but we did not retain the desire to understand all the details within those libraries.
Attackers targeting our applications or libraries can use techniques that exploit even the smallest problems in our code. Even if you write the code correctly, in 99% of cases, that remaining 1% can make your application just as vulnerable as if you had not implemented any protection at all.
Let's see an example of such an attack through popular open-source packages.
Damaged NPM libraries
NPM (Node Package Manager) is the most used package manager for JavaScript in Node.js. Through NPM, we can install and manage packages for our JavaScript applications.
Users of popular open-source packages "colors" and "faker" were stunned when they saw their applications crashing and displaying nonsense, affecting even thousands of applications.
The creator of these packages intentionally included an infinite loop that crashed hundreds of applications that rely on these packages. These loops print nonsensical non-ASCII characters on the consoles of all affected applications and continue to execute indefinitely, thus causing crashes.
The real motive behind this action was retaliating against mega-corporations and commercial users of open-source projects who heavily rely on free community-contributed software without giving back.
Best practices for selecting and using open-source libraries
Given these challenges, it is important to adopt cautious and strategic practices when selecting and using open-source libraries. Here are some recommendations to ensure the reliability and security of your applications
Be careful about which packages you use. Not all packages are maintained with the same level of security and reliability.
Choose packages maintained by established consortia dedicated to improving and maintaining software. This ensures ongoing support and updates.
Prefer using source code over binary whenever possible. This recommendation is especially important because binary files imply a much higher level of risk since it is ultimately impossible to verify that they were built with the associated source code. The best approach would be to directly use the source code, check its integrity, and analyze its vulnerability before using it in application development.
Top-tier code is a secure code
We can ensure a certain level of security by using various tools to check for vulnerabilities in our code, such as:
OWASP ZAP - The most popular tool for testing the security of web applications.
MobSF - Provides automated security testing for mobile applications.
SonarQube - Used for analyzing and testing the quality and security of code in various programming languages.
These tools can detect various vulnerabilities in web applications and mobile applications, including compromised authentication, exposure of sensitive data, incorrect security configurations, SQL injection attacks, cross-site scripting, unsafe data deserialization, and components and libraries with known vulnerabilities.
**What can companies do today to protect their data?**
Today, security is more necessary than it was 10 years ago. From HTTP anomalies, SQL injection attacks, and cross-site scripting (XSS) to attempts at account takeovers and malicious bots.
To ensure the security of our applications, it is crucial that every company operating on the web does not compromise security for the speed of delivering new applications or functionalities. Most importantly, the company must maximize the security of its end-users' data.

It is an... | 0 | 2024-06-13T10:52:16 | https://dev.to/debasmita-a/5-top-casting-options-in-selenium-webdriver-api-4f5b | selenium, webdriver, remotewebdriver, topcasting | ## Introduction :
WebDriver API is one of the 3 components provided by Selenium. It is an interface that has many declared methods that help perform certain actions on the browser.
In this article, we will investigate all 5 top casting combinations while creating a browser driver object (ChromeDriver, EdgeDriver, FirefoxDriver, etc.) and see why they are not all suitable to use.
This is also very often asked in automation testing interviews, to explain the WebDriver API hierarchy and the different type castings.
## SearchContext interface :
_SearchContext_ is the parent interface to WebDriver and WebElement interfaces. it has two methods : findElement() and findElements().
## WebElement interface :
_WebElement_ is an interface and it has several methods that help performing certain actions on elements on the web page. Every element on a web page is known as web elements in Selenium.
## WebDriver interface :
_WebDriver_ is an interface. WebDriver API is the one that launches and performs actions on the browser. It has methods to manipulate the browser components.
It has child classes that we use extensively, such as : ChromeDriver, ChromiumDriver, EdgeDriver, FirefoxDriver, InternetExplorerDriver, RemoteWebDriver, SafariDriver etc.
## RemoteWebDriver class :
_RemoteWebDriver_ class is the concrete class that implements all the declared methods of its parent and grand parent interfaces.
## ChromiumDriver class :
_ChromiumDriver_ class’s direct parent class is _RemoteWebDriver_. It has child classes such as ChromeDriver and EdgeDriver.
## 5 different top castings to create a driver object :
Now, let’s analyze different type castings among the WebDriver API while creating a browser driver object. And we will see why some of them don’t work. Here, we will take ChromeDriver as example browser driver class.
### 1. SearchContext and ChromeDriver top casting :
```
SearchContext driver = new ChromeDriver();
```
In this case, the driver will have only two methods : findElement() and findElements() coming from SearchContext. This top casting is kind of moot, as we won’t be able to launch the browser to perform any action.
### 2. ChromiumDriver and ChromeDriver top casting:
```
ChromiumDriver driver = new ChromeDriver();
```
Here, only ChromiumDriver specific methods will be available to the driver. That means, the ChromiumDriver class provides certain methods which are useful to a chromium browser i.e ChromeDriver and EdgeDriver.
As ChromiumDriver inherits from RemoteWebDriver class, the methods such as get(String url), findElement(By locator), findElements(By locator), manage(), close(), quit() etc. will be available to the driver object reference.
So if one wants to perform cross browser testing, it won’t be possible.
### 3. ChromeDriver class : (not a top cast)
```
ChromeDriver driver = new ChromeDriver();
```
In this case also, we will have only ChromeDriver class specific methods available. ChromeDriver inherits from ChromiumDriver and hence, methods like get(String url), findElement(By locator), findElements(By locator), manage(), close(), quit() etc. will be available to the driver object reference.
And obviously, cross browser testing will not be possible.
### 4. RemoteWebDriver and ChromeDriver top casting :
```
RemoteWebDriver driver = new ChromeDriver();
```
RemoteWebDriver is the **concrete** class that has **implementations** of all WebDriver and WebElement interface declared methods. It is a valid top casting.
Here, we have a RemoteWebDriver type reference variable, which can be referenced to a FirefoxDriver or EdgeDriver class object if needed. As it is a parent class, it is not limited to specific browser driver object types as in case of ChromiumDriver type reference. (in points 2 and 3)
### 5. WebDriver and ChromeDriver top casting :
```
WebDriver driver1 = new RemoteWebDriver("remoteAddress",capabilities);
WebDriver driver2 = new ChromeDriver();
```
WebDriver interface is the grand parent interface to ChromeDriver class. As ChromeDriver is already inheriting from RemoteWebDriver class, all implemented methods will be available to the ChromeDriver object.
Also, we have a WebDriver type reference variable, which can be referenced to a FirefoxDriver or EdgeDriver class objects if needed.
The first driver reference driver1 will launch the browser on a remote machine.
## Conclusion :
All the above top castings are valid of course. It’s not like there will be any compiler error or runtime exceptions. But all of them won’t be useful to our requirements, as they shouldn’t. The hierarchy is designed to be used in a certain way.

{% embed https://www.youtube.com/watch?v=ztjMkfeFNrg&ab_channel=AdeelImran %}
---
### Objective
To improve immutability and type safety in TypeScript by leveraging the `as const` feature.
### Section 1: Using `Object.freeze` for Immutability
`Object.freeze` is a method provided by JavaScript that makes an object immutable. When an object is frozen, you cannot add, delete, or modify its properties.
**Example:**
```typescript
const routes = {
home: '/',
about: '/about',
contact: '/contact'
};
Object.freeze(routes);
// Attempting to modify properties will fail
routes.home = '/new-home'; // Error: Cannot assign to 'home' because it is a read-only property.
```
**Key Points:**
1. **Top-Level Immutability:** `Object.freeze` ensures that the object `routes` is read-only at the top level.
2. **Nested Objects:** For complete immutability, nested objects require individual wrapping with `Object.freeze`.
### Section 2: Leveraging `as const` for Immutability and Type Safety
The `as const` feature in TypeScript enhances immutability and type safety by converting the values of an object into their literal types.
**Example:**
```typescript
const routes = {
home: '/',
about: '/about',
contact: '/contact'
} as const;
// The type of `routes` is now:
// {
// readonly home: "/",
// readonly about: "/about",
// readonly contact: "/contact"
// }
```
**Key Points:**
1. **Literal Types:** `as const` converts the values into their literal types, providing precise type safety.
2. **Read-Only Properties:** All properties become read-only, ensuring immutability without requiring `Object.freeze`.
### Section 3: `as const` vs. Enums
While enums provide a way to define a set of named constants, `as const` offers a more intuitive and flexible approach for certain scenarios.
**Example Comparison:**
Using Enums:
```typescript
enum Routes {
Home = '/',
About = '/about',
Contact = '/contact'
}
function goToRoute(route: Routes) {
// Logic to navigate to the route
}
goToRoute(Routes.Home);
```
Using `as const`:
```typescript
const routes = {
home: '/',
about: '/about',
contact: '/contact'
} as const;
type Routes = keyof typeof routes;
function goToRoute(route: Routes) {
// Logic to navigate to the route
}
goToRoute('home'); // Type-safe and more intuitive
```
**Benefits of `as const`:**
1. **Improved Type Safety:** Using `as const` with `keyof typeof` ensures that only valid keys are used.
2. **Intuitive Syntax:** The syntax is straightforward and more closely aligned with JavaScript objects.
3. **Better Autocomplete:** IDEs provide better autocomplete suggestions with `as const`, enhancing the developer experience.
By integrating these techniques, you can effectively master immutable types with TypeScript using the `as const` feature. Enhance your coding skills and ensure your applications are both robust and maintainable.

1,886,834 | 4 Ways to backup mySql database to a csv file | There are several methods to create a CSV backup of your MySQL database. Some third-party database... | 0 | 2024-06-13T10:44:01 | https://dev.to/instanceofgod/4-ways-to-backup-mysql-database-to-a-csv-file-3e9j | There are several methods to create a CSV backup of your MySQL database. Some third-party database management tools offer additional features for backing up to CSV.
If you prefer command-line control, the mysqldump utility is powerful and flexible. If you are familiar with the python programing language, there are packages to help you write python scripts to backup your database. The method you choose depends on your comfort level and technical expertise
In this article, i share 4 different ways to backup your MySQL database to a CSV file.
## Using `mysqldump` and `mysql` Command-Line Tools
1. **Export the Database to SQL File**
Use `mysqldump` to create a dump of your database. This step is optional but useful for backing up the entire database structure and data.
```bash
mysqldump -u username -p database_name > database_backup.sql
```
Replace `username` with your MySQL username, `database_name` with the name of the database, and `database_backup.sql` with the name you want for your backup file.
2. **Export Table to CSV File**
You can export a specific table to a CSV file using the `SELECT` statement with `INTO OUTFILE` in MySQL. Here’s how you can do it:
```sql
SELECT * FROM table_name
INTO OUTFILE '/path/to/your/file.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';
```
Replace `table_name` with the name of the table you want to export, and `/path/to/your/file.csv` with the full path where you want to save the CSV file.
- Ensure the MySQL server has the appropriate permissions to write to the specified path.
- The `FIELDS TERMINATED BY ','` specifies that fields are separated by commas.
- The `ENCLOSED BY '"'` ensures that fields are enclosed in double quotes.
- The `LINES TERMINATED BY '\n'` specifies the end of a row.
3. **Run the SQL Command**
You can execute the SQL command directly through the MySQL shell or using a script. Here’s how to do it from the MySQL shell:
```bash
mysql -u username -p database_name -e "SELECT * FROM table_name INTO OUTFILE '/path/to/your/file.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n';"
```
Replace the placeholders with your actual database details.
### Example in MySQL Shell
1. Log in to MySQL:
```bash
mysql -u username -p
```
2. Select the database:
```sql
USE database_name;
```
3. Export the table:
```sql
SELECT * FROM table_name
INTO OUTFILE '/path/to/your/file.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';
```
***Permissions Note***
- Make sure the MySQL user has the `FILE` privilege to write files to the server.
- The directory specified in the `INTO OUTFILE` path must be writable by the MySQL server process.
## Using a Bash Script
For automation, you can create a script (e.g., `db_backup.sh`) to export the table:
```bash
#!/bin/bash
DB_USER="username"
DB_PASS="password"
DB_NAME="database_name"
TABLE_NAME="table_name"
OUTPUT_FILE="/path/to/your/file.csv"
mysql -u $DB_USER -p$DB_PASS -e "SELECT * FROM $TABLE_NAME INTO OUTFILE '$OUTPUT_FILE' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n';"
```
Make the script executable:
```bash
chmod +x db_backup.sh
```
The run the script:
```bash
./db_backup.sh
```
## Using Python and the pandas library
1. **Install the necessary packages**:
You need to install `pandas` and `mysql-connector-python` (or `PyMySQL`) to connect to the MySQL database and manipulate the data.
```bash
pip install pandas mysql-connector-python
```
2. **Create a Python script**:
sample script to export a MySQL table to a CSV file using `pandas`.
```python
import pandas as pd
import mysql.connector
# Database configuration
db_config = {
'user': 'username',
'password': 'password',
'host': 'localhost',
'database': 'database_name'
}
# SQL query to select data from the table
query = "SELECT * FROM table_name"
# Connect to the MySQL database
connection = mysql.connector.connect(**db_config)
# Read data from the database into a pandas DataFrame
df = pd.read_sql(query, connection)
# Close the connection
connection.close()
# Export the DataFrame to a CSV file
output_file = '/path/to/your/file.csv'
df.to_csv(output_file, index=False)
print(f"Data has been exported to {output_file}")
```
### Code Explanation
1. **Database Configuration**:
- Replace `'username'`, `'password'`, `'localhost'`, and `'database_name'` with your actual database credentials.
2. **SQL Query**:

***Note: The subprocess module in Python is used to spawn new processes, connect to their input/output/error pipes, and obtain their return codes***
It allows you to run external commands and interact with them programmatically. This is especially useful for automating command-line tasks and integrating external tools into your Python scripts.
Key Functions in subprocess
subprocess.run(): This function runs a command, waits for it to complete, and then returns a CompletedProcess instance.
subprocess.Popen(): This is a more powerful and flexible function for spawning new processes. It allows more complex interactions with the process.
Example Usage
Here’s a simple example demonstrating the use of subprocess.run():
```python
import subprocess
# Define the command to run
command = ['echo', 'Hello, World!']
# Run the command
result = subprocess.run(command, capture_output=True, text=True)
# Print the command's output
print(result.stdout)
```
***Explanation of Parameters:***
command: A list where the first element is the command to run, and the subsequent elements are the arguments to the command.
capture_output: If set to True, it captures the standard output and standard error.
text: If set to True, the output is returned as a string instead of bytes.
NOTE: the csvkit command an also be run as a one line command using if you have csvkitn installed. You can install csvkit with `pip install csvkit`:
```bash
csvsql --db mysql://[username]:[password]@localhost/[database_name] --query "SELECT * FROM [table_name]" > [output_file.csv]
```

While this technology can be used for security and convenience, it also raises concerns about privacy and surveillance.
Consider a bustling city department store during the holiday season, teeming with shoppers. Amidst the crowd, there is a regular customer – let’s call him John – browsing through the electronics section. As he examines a pair of headphones, the store’s facial recognition system, designed to detect and prevent theft, suddenly triggers an alert. The system, having erroneously matched John’s features with those of a known shoplifter from its database, flags him as a suspect.
Store security, relying on the system’s accuracy, escorts John to a private room for questioning. Confused and embarrassed, John insists on his innocence. Meanwhile, the actual shoplifter could be taking advantage of the situation, continuing their malicious activities unnoticed.
John is detained for an hour, missing important meetings and enduring the stress of false accusation. After reviewing the surveillance footage, it becomes clear that the system made an error, and John is released with an apology. However, the damage is done.
This scenario underscores the potential consequences of relying too heavily on automated systems without adequate human oversight. In this blog, we will provide tips on how to protect your privacy in the age of facial recognition. We will explore how facial recognition works and how to avoid it.

1,885,423 | Database Management system(DBMS) Part1 | Hello guys, Hope everything is going well. I'm Esraa a frontend developer and postgraduate student... | 0 | 2024-06-13T10:38:14 | https://dev.to/esraanasr92/database-management-systemdbms-part1-4okm | Hello guys,
Hope everything is going well. I'm Esraa a frontend developer and postgraduate student at AAST in Computer Science. This semester, I'm studying three subjects Data structure and algorithms, Database Management Systems(DBMS), and Object object-oriented programming (OOP).
I'll contribute tutorials for each subject to share information, and if you have an external tutorial, please share it with us:).
So, get to the point. What is the meaning of Data? What is the difference between Data and Information? Why do we need this information?
**Data:** refers to raw facts, building blocks of information. Unprocessed information.
**Information:** data is processed to reveal meaning (ذات معنى)
If we have accurate, relevant, and timely information we have a key to effective decision-making. effective decision-making is the key to survival in the global environment.
**Database:** Shared, integrated computer structure that houses
End user data (raw facts)
Metadata (data about data)
Let's go further and discover a database management system.
Do you consider how may I manage and control access to data? Is it possible to share it? How can I make data more effective and efficient?!
DBMS can answer all questions about this point because:
- It's a collection of programs that manage database structure and control access to data.
- It's possible to share data among multiple apps or users.
- Make database management more efficient and effective.
Feature on details:
- Support massive amounts of data
- Giga/tera/petabytes
- Far too big for main memory
- Persistent storage
- Programs update, query, manipulate data.
- Data continues to live long after program finishes.
- Efficient and convenient access
- Efficient: do not search entire database to answer a query.
- Convenient: allow users to query the data as easily as possible.
- Secure, concurrent, and atomic access
- Allow multiple users to access database simultaneously.
- Allow a user access to only to authorized data.
- Provide some guarantee of reliability against system failures.
**Last but not least**
Here's a diagram for a type of database and location

```python
class Order(BaseModel):
class Status(models.TextChoices):
COMPLETE = "Complete"
PENDING = "Pending"
CANCELLED = "Cancelled"
created_by = models.ForeignKey(
User, on_delete=models.CASCADE, related_name="orders", null=True, blank=True
)
vendor = models.ForeignKey(
Vendor,

)
notes = models.TextField(null=True, blank=True)
email_sent = models.BooleanField(default=False)
def save(self, *args, **kwargs):
if not self.order_number or self.order_number == "":
self.order_number = self.generate_unique_order_number()
super().save(*args, **kwargs)
def generate_unique_order_number(self):

db_persist=True,
)
def __str__(self) -> str:
return f"{self.order.order_number} - {self.product.name} - {self.total}"
```
### TASK DEFINITION
The task at hand is to automatically update an `Order` status once all related `OrderItems` instances have been marked as `Received`.
To achieve this, we are going to tap into the almighty Django signals that ships out of the box.
So the first step is to create a `signals.py` file in our app folder:
```bash
touch core/signals.py
```
And register it in the `core/apps.py` file as so:
```python
from django.apps import AppConfig
class CoreConfig(AppConfig):
default_auto_field = "django.db.models.BigAutoField"
name = "core"
def ready(self):
from .import signals
```
Once that is out of the way we can start by writing the signal function that will ensure all an order item is marked as complete once all orderitems are updated as received.
The function for that looks like:
```python
from django.db.models.signals import post_save
from django.dispatch import receiver
from .models import Order, OrderItem
@receiver(post_save, sender=OrderItem)
def update_order_status(sender, instance, **kwargs):
order = instance.order
if order.items.filter(status=OrderItem.Status.PENDING).exists():
if order.status == Order.Status.COMPLETE:
order.status = Order.Status.PENDING
order.save()
return
# If all items are received, update the status of the order to Complete
order.status = Order.Status.COMPLETE
order.save()
```
So basically when an OrderItem is updated, our signal checks if the Order associated to that OrderItem has any OrderItem with a status of `Pending` which should mean that not all related OrderItem instances have been received.
If that is the case the signal checks if the Order status is set to `Complete`. If that is the case, it reverts the status to `Pending`.
If all OrderItem instances have been received, i.e status is `Received`, it is time to mark that Order as complete.
And that works okay after I run the tests.
### SECOND TASK DEFINITION
The reverse is true, if an Order gets marked as `Complete`, our backend should mark all related OrderItem instances as `Received`. This calls for another signal function to do that right?
I have written it and it looks like:
```python
@receiver(post_save, sender=Order)
def mark_order_items_received(sender, instance, **kwargs):
if instance.status == Order.Status.COMPLETE:
order_items = instance.items.all()
for order_item in order_items:
order_item.status = OrderItem.Status.RECEIVED
order_item.save()
```
So what it does is to check, upon saving, if an Order is set to `Complete` and if that is the case it loops through all related OrderItem instances, setting them to `Received`.
However this causes an infinite execution loop since we have another signal that listens on OrderItem upon saving so our signals will recursively execute and Django will show the following screen.
That seems to spoil our fun little party :(
I had to do some research and even ended upon consulting with ChatGPT so that I can get a way out. After a number of iterations, I learnt that we can also connect and disconnect from signal at will!
This looked like it would solve this whole recursive mess. So armed with this new knowledge, I made the following code edits to toggle the signals on and off.
```python
from django.db.models.signals import post_save
from django.dispatch import receiver
from .models import Order, OrderItem
# Disable signal during certain operations to prevent recursion
def disable_signals():
post_save.disconnect(update_order_status, sender=OrderItem)
post_save.disconnect(mark_order_items_received, sender=Order)
def enable_signals():
post_save.connect(update_order_status, sender=OrderItem)
post_save.connect(mark_order_items_received, sender=Order)
@receiver(post_save, sender=OrderItem)
def update_order_status(sender, instance, **kwargs):
order = instance.order
if order.items.filter(status=OrderItem.Status.PENDING).exists():
if order.status == Order.Status.COMPLETE:
order.status = Order.Status.PENDING
order.save()
return
# If all items are received, update the status of the order to Complete
order.status = Order.Status.COMPLETE
order.save()
@receiver(post_save, sender=Order)
def mark_order_items_received(sender, instance, **kwargs):
if instance.status == Order.Status.COMPLETE:
# Disable signal to prevent recursion
disable_signals()
order_items = instance.items.all()
for order_item in order_items:
order_item.status = OrderItem.Status.RECEIVED
order_item.save()
# Enable signal after performing the operation
enable_signals()
```
In this updated code,I have defined two methods:
```python
# Disable signal during certain operations to prevent recursion
def disable_signals():
post_save.disconnect(update_order_status, sender=OrderItem)
post_save.disconnect(mark_order_items_received, sender=Order)
```
Which essentially toggles of the two signals functions.
```python
def enable_signals():
post_save.connect(update_order_status, sender=OrderItem)
post_save.connect(mark_order_items_received, sender=Order)
```
Which turns them back on.
Since the problem spawned from the second function, that is where I will be placing the toggle functions. Only if an Order status is `Complete`. The rest of the code remains the same.
And as predicted, this solution fixed the infinite loop of execution that I was facing before :).
Before moving on to the next thing, lest I forget I decided to document my experience for posterity haha😂.
See you on the next one.

There is a flood of frameworks being introduced frequently, each one asserting to be a silver bullet for creating that next great thing. However, with lots of options available, it can be overwhelming to choose the right technology. This abundance of choices can definitely make selecting the right technology a daunting task. [**.NET development services**](https://www.webcluesinfotech.com/dot-net-development-company/) can help you navigate these waters.
**Introduce .NET:**
.NET; welcome a strong and flexible framework that has kept its course in the development arena for 20+ years.
Introduce the Blog's Purpose:
Why must you go for .NET in your next application building on your next app project? As such this blog takes you through technical advantages which sets .NET apart from other things such as its cutting edge speed and security features.
Focus on Value Proposition:
Whether you are developing some complex enterprise applications or attractive mobile apps, .NET provides tools and capabilities which help bring whatever you want into reality. By the time we finish this blog, you will have gained enough knowledge to tell whether or not .NET meets your development needs well.
**Unveiling the Advantages of Dot Net Development:**
**Performance Prowess:**
In this rapidly changing world of today, the application performance is the king. Applications that are super-fast and responsive, as it were, are what users want; otherwise they can become frustrated and drop off. Here is where .NET excels.
One of its major factors leading to exceptional performance is Just-In-Time (JIT) compilation in .NET. Unlike interpreted languages that execute code line by line, .NET compiles code into machine code at runtime. The resultant compiled code runs significantly faster on the target machine’s processor hence resulting in a smoother application performance.
Another one is .NET’s strong garbage collection system. On slow applications, memory leaks have been known to cause misery.Memory allocation and deallocation activities are efficiently handled through.NET automatic garbage collection without causing memory leaks thus improving optimal application performance.
**Several benchmarks have consistently placed.NET among the top performers compared to other frameworks.**
While providing a good starting point for high performing apps,.NET can be boosted further by expert developers through various techniques.These include profiling code for identifying bottlenecks, programming asynchronously to allow non-blocking operations, or using efficient data structures for manipulating data quickly.
Developers used to create different applications for each platform (Windows, macOS, Linux, mobile) but now these days are gone.Today's users expect a seamless experience regardless of the device they use.. However,.NET allows cross-platform development due its cross-platform development approach..
- Xamarin: A robust framework that allows developers to create native mobile apps (iOS, Android) using C# and .NET libraries. Consequently ,app developers can leverage their existing expertise in.NET to build high-performance mobile applications.
- .NET MAUI (Multi-platform App UI): A newcomer on the scene,. NET MAUI has been designed for creating modern, cross-platform user interfaces that work on desktop, mobile and web applications using a single codebase.
The ability to reuse code across platforms provides significant advantages. It cuts down the development time and costs, promotes uniformity across applications as well as simplifies maintenance. Developers can focus on core functionalities instead of rewriting code for each platform.
Consider an example: suppose there is a business logic layer written in .NET that handles activities such as authentication of users, data processing or business rules. Hence this can be reused by an ASP.NET web application; a mobile app created through Xamarin as well as a desktop application developed with NET Windows Forms Application. Therefore it reduces time during development and maintains consistency across different platforms in terms of business logic.
Security is the most important aspect of life in today’s digital age.Security features are needed when developing applications dealing with sensitive data of users or financial transactions..NET offers developers a comprehensive security toolkit that helps protect apps against malicious attacks.
Authentication And Authorization: .NET provides for authenticating users (verifying user identity) and authorizing them (controlling user access to specific resources). To this effect, only authorized persons can gain entry into sensitive information and features within the application.
Data Encryption: For that reason, .NET has formidable and secure data encryption that protects confidential information when it is stored or transferred across a network. Thus, protected data cannot be accessed by intruders even if they catch it.
Secure Coding Practices: The programming principles in.NET framework itself have been designed to reduce the risks of security vulnerabilities which hackers can exploit. Furthermore,.NET encourages programmers to adopt safe coding practices like request validation and proper error handling so as to enhance the security levels of an application.
Continuous Security Updates:
Microsoft continues with its effort of maintaining security by regularly releasing security updates for.NET platform, which are meant to patch vulnerabilities and minimize potential risks. Therefore, continuous improvement in your.NET applications means tapping into these ongoing improvements in terms of security.
Embrace the Ecosystem:
However, their utilization may not be straightforward but beneficial because development frameworks usually depend on wider ecosystems providing several resources. For instance, rich ecosystems offer developers tools, libraries and other resources that speed up development time while improving code quality and addressing specific requirements. Nevertheless; a vast ecosystem that is dynamic empowers.net developers:
Extensive Libraries and Frameworks: In.NET space there are numerous pre-existing libraries as well as frameworks serving various purposes. Among them are ASP.NET for web development and Entity Framework for data access.
Open-Source Contributions: An active open-source community drives the.NET ecosystem which means there is plenty of open-source software programs available free of charge extending .NET framework’s capabilities enabling innovation by developers who need particular solutions.
Seamless Integration with Microsoft Tools: At the same time,.NET smoothly integrates with other Microsoft-written development tools including Visual Studio. By using this integration, coders acquire benefits like completion of codes or debugging tools associated with additional Microsoft products such as Azure or Active Directory.
Example: Think about someone who is developing a brand new e-commerce application using .NET. A person could use libraries such as Entity Framework to simplify the database connection; make use of open source libraries for cart and payment services; all under Visual Studio with which he is already familiar. It allows developers to focus on new features rather than re-creating old ones.
**Addressing Specific Needs with Dot Net Solutions:**
Beyond its general benefits, .NET has a more flexible nature. This makes it an attractive option for different cases since it caters to specific development needs.
**Enterprise-grade Applications:**
When it comes to complex enterprise applications that require scalability, reliability and security, .NET is the best. It has a robust architecture that can handle big amounts of data and concurrent users, thus ensuring smooth operation even under heavy workload.
- Scalability: To meet the ever-growing user demands, .NET applications can be horizontally scaled by adding more servers or vertically scaled by adding more resources to the existing servers. Consequently, this ensures improved performance when there is increased traffic and data volume in the application.
- Reliability: The stability and reliability of.NET applications are widely known. Therefore, little downtime as well as an excellent user experience are achieved due to automatic memory management and strong error handling among others in place.
- Security: I had earlier highlighted how Microsoft’s innate security features in .NET make it perfect for systems that will hold sensitive data.
Additionally, other Microsoft technologies easily integrate with .NET:
- Azure: Cloud computing platform like Microsoft Azure allows easy deployment and management of.NET applications. Therefore, on-demand scalability, global reach and simplified application management are feasible through this framework.
- Active Directory: User authentication and authorization within a firm’s existing infrastructure is done with Active directory into which .NET leverages. As a result, secure access control and easy user administration come out of this move.
**Cloud-Native Development:**
Cloud-native principles such as microservices and containers have become part of today's development landscape. Accordingly , this leads to cloud-native application building using.NET:
- Microservices Architecture: Decomposing.NET applications into smaller independent microservices can promote modularity hence making it easier to deploy them besides scaling individual services differently .
- Containerization: Containers are self-contained units of code as well as their dependencies where.NET applications can be packaged for deployment purposes. As such, this enables consistent deployment across different environments and cloud platforms.
- Integration with Azure: Like mentioned before, .NET’s seamless integration with Azure empowers developers to take advantage of cloud-native features like container orchestration and serverless computing. To sum up, this has simplified it for the deployment and management of.NET applications in the cloud.
**Building with Confidence: The Dot Net Development Process:**
**Dynamic Development Experience**
The choice of the right development tools has a massive impact on the development process. .NET offers developer-friendly experience that is able to simplify the whole workflow.
Visual Studio: Visual Studio is a major dev environment for .NET applications and it has multiple features such as code completion, debugging tools, built-in unit testing frameworks and integration with other Microsoft products that can enhance developers’ productivity.
Clean Code and Maintainability: With .NET framework, clean well-structured code can be written which allows more maintainable applications since there are plenty libraries and pre-built components.
**Massive Active Developer Community:**
A productive developer community is indispensable to any development environment. Here are some advantages of having a large active.NET community:
Knowledge Sharing and Support: A number of online resources exist that provide tutorials, forums where developers learn from each other besides addressing development-related challenges they come across during their programming activities.
Skilled Developer Talent Pool: There are many skilled.NET developers available because it is popular among programmers; hence firms will not struggle much to get the best people who can build as well as maintain their.NET applications.
**Conclusion:**
In conclusion, .NET has marked itself in app development as a powerful and versatile competitor. Its outstanding results, strong security characteristics, and ability to work on different platforms make it suitable for various applications. Whether developing an intricate corporate program, a beautiful mobile application or building a micro service-oriented cloud, .NET provides the tools and resources for making your dreams come true.

## Regular Expression and its usage:
A regular expression, often referred to as regex or regexp, is a sequence of characters that defines a search pattern. It is a powerful tool used for pattern matching and manipulating text data. Regular expressions are widely used in various programming languages, text editors, and command-line tools.
Regular expressions consist of a combination of literal characters and special characters called metacharacters. Metacharacters have special meanings and allow you to define patterns using features like repetition, alternation, grouping, and more.
The usage of regular expressions can vary depending on the context, but here are some common scenarios:
* **Pattern Matching:** Regular expressions are primarily used for pattern matching in strings. They allow you to search for specific patterns or sequences of characters within a larger text. For example, you can use a regular expression to find all phone numbers in a document or to extract email addresses from a string.
* **Validation:** Regular expressions are often employed for data validation. They can help ensure that user input follows a specific format or pattern. For instance, you can use a regular expression to validate whether a given string is a valid credit card number, date, or URL.
* **Text Manipulation:** Regular expressions can be used to manipulate text by performing search and replace operations. You can search for a specific pattern and replace it with another string or modify its format.
* **Parsing and Extracting Data:** Regular expressions are handy for parsing and extracting data from structured text. For example, you can use regular expressions to extract information from log files, scrape data from web pages, or parse HTML or XML documents.
* **Lexical Analysis:** Regular expressions play a crucial role in lexical analysis, which is the process of tokenizing and analyzing the structure of a programming language. They are used to define the syntax rules for identifying keywords, operators, and other language constructs.
> While regular expressions are a powerful tool, they can also be complex and require careful crafting to ensure accuracy and efficiency. Additionally, different programming languages may have slight variations in their regular expression syntax.

Support for ESM needs to be added in various ways, it would be fine to break down logic into smaller functions for testing, but that makes the code a bit cumbersome to manage, and I also wanted to test changes in state, which was the start of it all.
Benefits I've considered by deciding on Redux:
+ Makes it easier to transition to a different framework in the future
+ Less affected when updating from v4 to v5
+ Improves maintainability
Disadvantages I've considered:
+ Increases the amount of code
+ Requires various adjustments to operate in Svelte
Here is a rough code snippet like below👇
__Store.redux.ts__
```ts
import { configureStore, createSlice } from '@reduxjs/toolkit';
export interface MenuFormStore {
name: string;
}
const initialState: MenuFormStore = {
name: '',
};
const menuFormSlice = createSlice({
name: 'menuForm',
initialState,
reducers: {
setName: (state, action: { payload: string }) => {
state.name = action.payload;
}
}
});
const MenuFormActions = menuFormSlice.actions;
const menuFormStoreRedux = configureStore({
reducer: menuFormSlice.reducer
});
const MenuFormDispatch = menuFormStoreRedux.dispatch;
export const MenuFormReduxStoreModule = {
initialState,
Actions: MenuFormActions,
Store: menuFormStoreRedux,
Dispatch: MenuFormDispatch
} as const;
```
This file has nothing to do with Svelte, so you can write unit tests directly with Jest.
However, this alone does not make it reactive on Svelte, so we define a read-only store in a separate file using `readonly` from `svelte/store` like below (placing it in the same file will anger Jest)
__Store.ts__
```ts
import { onMount } from 'svelte';
import { writable, readonly } from 'svelte/store';
import { MenuFormReduxStoreModule } from './MenuForm.redux';
const state = writable(MenuFormReduxStoreModule.initialState);
export const getMenuFormStore = () => {
onMount(() =>
MenuFormReduxStoreModule.Store.subscribe(() => {
state.update(prev => ({ ...prev, ...MenuFormReduxStoreModule.Store.getState() }));
})
);
return readonly(state);
};
```
Usage within Svelte would be as below👇
__Menu.svelte__
```html
<script lang="ts">
import { getMenuFormStore } from './Store';
import { MenuFormReduxStoreModule } from './Store.redux';
$: menuFormStore = getMenuFormStore();
const { Actions, Dispatch } = MenuFormReduxStoreModule;
</script>
<div>
{$menuFormStore.name}
<input on:input={e => Dispatch(Actions.setName(e.currentTarget.value))}/>
</div>
```
## In Conclusion
Likely the same system could be used for jotai or zustand, which is appreciated since many issues are resolved in Svelte v5. | qaynam |

As machine learning technologies become increasingly prevalent, the need to ensure the privacy and security of the data used to train these [**LLMs**](https://blogs.novita.ai/top-llms-for-2024-how-to-evaluate-and-improve-an-open-source-llm/) has become a critical concern. One key approach to addressing this challenge is the use of differential privacy (DP) techniques.
In this article, we will delve into the concept of **Large Language Models differential privacy**, exploring how it works, the challenges involved, and the potential solutions being explored by researchers. By understanding the intricacies of DP for LLMs, we can gain insights into the broader implications of privacy-preserving machine learning.
## What Is Large Language Models Differential Privacy?
Differential privacy (DP) is a rigorous mathematical framework for training machine learning models, including large language models like GPT-3 and BERT, in a way that provably protects the privacy of the training data. The core principle is to ensure the model's outputs do not reveal too much information about any individual data point used during the training process. This is achieved through a combination of techniques applied throughout the model training pipeline.
## How Does Large Language Models Differential Privacy Work?
### 1 Gradient Clipping
Gradient clipping is a key technique for enforcing differential privacy during language model training.
Imagine the training data as a mountain range, and the gradients (updates to model parameters) as ropes attached to different peaks. Without clipping, some ropes would be very thick, corresponding to training examples with outsized influence. This allows the model to "memorize" specific data, compromising privacy.
Gradient clipping puts a strict limit on the thickness of these ropes. No single rope can be thicker than the limit. This ensures the model updates draw equally from all training data, preventing any one example from dominating.
It's like capping the ropes to make the mountain peaks more even. This makes it much harder to identify and extract information about specific training data.
### 2 Adding Noise
After clipping the gradients (ropes) to a fixed thickness, we add random noise to them. Imagine spraying each rope with a fine mist - the mountains are now obscured by a hazy cloud. This further prevents any single training example from standing out and being identified, reinforcing the differential privacy guarantees.
### 3 Tracking Privacy Loss
We carefully keep tabs on the "privacy budget" being spent as the model is trained. Each update to the model parameters, each batch of training data processed, incurs a small amount of privacy loss. It's like we're keeping a running tally, making sure the total amount of "privacy spent" doesn't exceed a safe limit, even after seeing millions of training examples. This rigorous accounting ensures the final model respects the desired level of differential privacy.
The end result is a language model that has been trained in a privacy-preserving way. It can then be used without revealing sensitive information about the individuals whose data was used to create it. Of course, there is usually some tradeoff in terms of the model's overall performance, but researchers are working to minimize this.
## What Are the Problems of Large Language Models Differential Privacy?
### Disparate Impact on Model Accuracy
- Applying differential privacy (DP) techniques like gradient clipping and adding noise to the training process has a disproportionately negative impact on the accuracy of large language models (LLMs) for underrepresented or minority subgroups in the data.
- For example, in the gender and age classification tasks, the DP-trained models exhibited much lower accuracy on faces with darker skin tones compared to lighter skin tones. This was not the case for the non-DP models.
- The "the poor get poorer" effect means the DP training hurts accuracy the most for the classes or subgroups that already had lower accuracy in the original, non-DP model. So it amplifies the unfairness of the model.
- This happens because the DP mechanisms like gradient clipping and noise addition have an outsized effect on the gradients and training signal coming from the underrepresented or harder-to-learn parts of the data. The model ends up biased even more towards the majority, simpler subgroups.
### Challenges with Large/Complex Models
- Modern large language models like GPT-3 or BERT have billions of parameters and immense complexity. Applying DP techniques to these models is computationally very expensive and challenging.
- The gradients in these complex models may be too sensitive to the random noise required for DP. This sensitivity limits the accuracy that can be achieved with DP training, even after extensive hyperparameter tuning. The DP model's performance simply plateaued far below the non-DP version.
### Privacy-Utility Tradeoff
- To maintain a reasonable privacy budget, as measured by the DP parameter ε being less than 10, the DP-trained LLMs often suffer substantial drops in accuracy compared to their non-DP counterparts.
- Increasing the privacy budget could improve the model's accuracy, but this comes at the cost of much higher privacy leakage, which may be unacceptable in many real-world applications.
- There is a fundamental tension between preserving privacy and maintaining high utility (accuracy) of the language model. Achieving both simultaneously is extremely challenging.
### Difficulty Combining DP with Other Fairness Techniques
- Standard techniques used to improve the fairness of machine learning models, like oversampling or reweighting underrepresented groups, are incompatible with the sensitivity constraints required for differential privacy.
- The documents note that the DP mechanisms, such as gradient clipping and noise addition, essentially override or negate the effects of these fairness-promoting techniques.
## Is There a Way to Ensure Both Privacy and Model Performance?
Typically, when you apply the standard differential privacy (DP) optimization techniques like DP-SGD to train large language models, the performance ends up much worse than non-private models. This is because the noise added for privacy protection tends to scale with the model size, and large models have high-dimensional gradients.
Interestingly, in the paper titled _Large Language Models Can Be Strong Differentially Private Learners_ by Xuechen Li, Florian Trame, Percy Liang and Tatsunori Hashimoto from Stanford University and Google Research presented a way to balance both privacy and model performance. To obtain this balance, the authors take a few smart approaches. Same as before, if research details do not interest you, just skip to the next section about an efficient solution for your own project.
### 1 Leveraging Pretrained Language Models
The authors found that using large, pretrained language models like BERT and GPT-2 as the starting point for fine-tuning was much more effective than training a new model from scratch. These pretrained models have already learned rich linguistic knowledge, so fine-tuning them with differential privacy is easier than trying to learn everything from the limited private training data.
### 2 Tuning Differentially Private Stochastic Gradient Descent (DP-SGD) Hyperparameters
The authors discovered that DP-SGD is highly sensitive to the choice of hyperparameters. Contrary to the typical small batch sizes and learning rates used in non-private fine-tuning, they found that using much larger batch sizes (e.g. 2048) and learning rates (e.g. 2^-5) led to significantly better performance under the same privacy budget. This suggests the standard hyperparameter settings for non-private learning are not well-suited for DP optimization.
### 3 Aligning Fine-tuning Objective with Pretraining
The authors observed that fine-tuning objectives more closely aligned with the original pretraining objective of the language model tended to work better under differential privacy. For example, instead of just predicting the sentence classification label, they had the model also predict missing words in the sentence - a task more similar to the language modeling pretraining. This allowed the model to better leverage the language understanding abilities learned during pretraining.
### 4 Introducing "Ghost Clipping"
A key challenge with DP-SGD is the high memory requirement of storing per-example gradients for the clipping step. The authors developed a new memory-efficient technique called "ghost clipping" that allows running DP-SGD on large Transformer models without this high memory cost. This technique generalizes the Goodfellow (2015) trick to handle sequential inputs, enabling DP fine-tuning with roughly the same memory as non-private training.
With these innovations, the authors are able to fine-tune large pretrained language models under differential privacy, and obtain models that match or even outperform strong non-private baselines. This shows it is possible to build practical private language models without sacrificing too much performance.
## Future Directions of Large Language Models Differential Privacy
### Developing Targeted DP Training Techniques
- The standard DP training approaches can sometimes have a disparate impact on underrepresented groups in the data.
- The idea is to explore adjusting the DP mechanisms, like clipping and noise addition, in a more targeted manner to better protect the privacy of underrepresented groups without unduly impacting their model performance.
- This could involve new DP training algorithms or modifications that are more sensitive to the needs of different data subgroups.
### Combining DP with Other Fairness Approaches
- Fairness and privacy can sometimes be at odds in machine learning.
- This direction aims to investigate how DP can be combined with other fairness-enhancing techniques, such as adversarial debiasing or causal modeling, while preserving the privacy-preserving properties of DP.
- The goal is to develop hybrid approaches that achieve strong privacy guarantees and improved fairness outcomes, especially for underrepresented groups.
### Understanding the Interaction Between DP and Fairness Notions
- Fairness can be defined in multiple ways, like equal opportunity or demographic parity.
- This direction focuses on understanding how DP interacts with these different fairness criteria, particularly in the context of large language models.
- Exploring this interaction can help researchers and practitioners navigate the trade-offs and synergies between DP and various fairness notions.
### Analyzing DP's Impact on Model Generalization
- DP training can introduce noise and constraints that may impact a model's ability to generalize, especially for underrepresented and complex data subgroups.
- This direction aims to deepen the understanding of how DP affects the model's overall and subgroup-specific generalization performance.
- Gaining this understanding can inform the design of DP techniques that balance privacy, fairness, and generalization, particularly for challenging data subsets.
## Conclusion
As the use of large language models continues to grow, the need to balance their impressive capabilities with robust privacy protections has become increasingly important. The research efforts outlined in this article highlight the ongoing work to develop more effective and efficient differential privacy techniques for LLMs, with a focus on mitigating the disparate impact on underrepresented groups and finding ways to combine DP with other fairness-enhancing approaches.
By addressing the key challenges around computational complexity, sensitivity, and the privacy-utility tradeoff, researchers have shown it is possible to build practical private language models without sacrificing too much performance. As these advancements continue, we can expect to see the emergence of LLMs that not only deliver state-of-the-art performance but also uphold rigorous privacy standards, paving the way for a future where AI systems can be trusted to handle sensitive data with the utmost care and responsibility.

Creating this with CSS is not complicated, we are going to make use of gradients, but what I find really useful is the simplification and reuse of these with native CSS variables, also known as CSS Custom Properties.
## Let's start
To create a box with stripes inside, it's as simple as generating a `div` with `width` and `height` (we give it `width` and `height` since it doesn't have any content, if it did it wouldn't be necessary):
```html
<div class="stripes"></div>
```
```css
.stripes {
width: 200px;
height: 100px;
border: 2px solid orange;
}
```
Then, to create the stripes, it's as simple as generating a `linear-gradient` that repeats:
```css
.stripes {
width: 200px;
height: 100px;
border: 2px solid orange;
background: repeating-linear-gradient(
45deg, /* inclination */
black 0 15px, /* main color - breakpoint */
#FFEB3B 15px 30px /* secondary color - breakpoint */
)
}
```
I won't go into too much detail about what values can be assigned to a `repeating-linear-gradient`, but in this case we first indicate the inclination we want our gradient to have, then we tell it the main color (or initial color in any case) and the breakpoints we want.
In our example:
- Start with the black color at 0px and continue with the same color up to 15px
- From those 15px and up to 30px we assign the yellow color
- ...this repeats all the time completing the stripes.
And that's it to set up our stripes. But what if we want to have thinner stripes for example? or do we want them to have different colors?. Applying the BEM methodology, we could have something like this:
```css
.stripes {
width: 200px;
height: 100px;
border: 2px solid orange;
background: repeating-linear-gradient(
45deg,
black 0 15px,
#FFEB3B 15px 30px
)
}
.stripes--thin {
background: repeating-linear-gradient(
45deg,
black 0 5px,
#FFEB3B 5px 10px
)
}
.stripes--red-white {
background: repeating-linear-gradient(
45deg,
red 0 5px,
white 5px 10px,
)
}
```
But doing this implies repeating the same properties in each modifier but with different values. This is where CSS variables come into play.
## Refactoring with CSS variables
The first thing we will do is define the variables we will use and that will then be modified according to each case.
```css
.stripes {
--angle: 45deg; /* inclination variable */
--color-primary: black; /* main color */
--color-secondary: #ffeb3b; /* secondary color */
--breakpoint-primary: 0 15px; /* main breakpoint */
--breakpoint-secondary: 15px 30px; /* secondary breakpoint */
}
```
With this we already have our variables ready to use. In the definition of the variables, we are setting the default values. The next thing we will do is use those variables in our first stripe.
```css
.stripes {
background: repeating-linear-gradient(
var(--angle), /* 45deg */
var(--color-primary) var(--breakpoint-primary), /* black 0 15px */
var(--color-secondary) var(--breakpoint
) /* #ffeb3b 15px 30px */
}
```
Obtaining the same result as before:
And from here on, everything is much simpler.
Now we will create our modifiers, but the only thing we will have to write will be the new values of these variables.
So, in the case of our stripe with thin stripes:
```css
.stripes--thin {
--breakpoint-primary: 0 5px;
--breakpoint--secondary: 5px 10px;
}
```
And in our red and white stripe:
```css
.stripes--red-white {
--color-primary: red;
--color-secondary: white;
}
```
And this is it!
## Our final code
```html
<div class="stripes"></div>
<div class="stripes stripes--thin"></div>
<div class="stripes stripes--red-white"></div>
```
```css
.stripes {
--angle: 45deg; /* inclination variable */
--color-primary: black; /* main color */
--color-secondary: #ffeb3b; /* secondary color */
--breakpoint-primary: 0 15px; /* main breakpoint */
--breakpoint-secondary: 15px 30px; /* secondary breakpoint */
width: 200px;
height: 100px;
border: 2px solid orange;
background: repeating-linear-gradient(
var(--angle), // 45deg
var(--color-primary) var(--breakpoint-primary), // black 0 15px
var(--color-secondary) var(--breakpoint-secondary), // #ffeb3b 15px 30px
);
}
.stripes--thin {
--breakpoint-primary: 0 5px;
--breakpoint-secondary: 5px 10px;
}
.stripes--red-white {
--color-primary: red;
--color-secondary: white;
}
```
Here is the complete exercise on Codepen:
{% codepen https://codepen.io/alejuss/pen/ZEEdwEb %}
## Conclusion
In the end, the good thing about CSS variables is that we only define the variables we are going to reuse and then we just have to call them and modify them, without having to rewrite over and over again all the properties that use them.
Thanks for taking the time to read, any feedback will be welcome :)

---
As we all know, staying ahead means embracing the latest in technology and innovation fields. Recently, [SST](https://sst.dev/), a pioneer in serverless solutions, made a significant shift by moving away from the AWS Cloud Development Kit (CDK) to [Ion](https://ion.sst.dev/docs/), a new and promising framework.
This bold move signals a change in how developers will build, deploy, and manage cloud resources. With this article, I want to study the reasons behind SST's decision to transition to the new version, explore its benefits, and discover what it means for the future of cloud development.
**AWS CDK Concerns: Why It’s Not a Good Choice Anymore?**
First, let’s start with AWS CDK: what’s wrong with it in the context of SST?
Well, the first two versions of SST were basically the wrappers and enhancers of [AWS CDK](https://aws.amazon.com/cdk/). If we go to any construct of the first two versions of SST we will find [a connection to AWS CDK](https://github.com/sst/sst/blob/master/packages/sst/src/constructs/Bucket.ts) (look at imports):
In fact, these first two versions allowed us to use AWS CDK and SST together in one codebase. For example, SST never provided the constructs for Step Functions, but developers could seamlessly use AWS CDK’s constructs to describe and manage Step Functions, demonstrating the compatibility and extendibility of using both tools together.
The deployment process was based on AWS CDK as well, which included [Cloudformation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/Welcome.html) template generation and stacks deployment. However, the reliance on AWS CDK brought with it lots of limitations, particularly in terms of deployment speed and transparency, so that the deployment time was unpredictable.
Also, developers could often face the infamous _UPDATE_ROLLBACK_FAILED_ status and then you need special techniques to deal with the status as well as your panic attack.
, Medium](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fcqhnc6gf0w37qoqhuu5.png)
---
The worst nightmare was **cycling dependencies of stacks**. This was not just a minor inconvenience - it fundamentally impacted how infrastructure updates could be managed. It also meant that if you need to update your infrastructure then you just update it.
For example, when you need to do something as simple as renaming a stack in the CloudFormation model, then you don't merely rename the existing stack but instead need to create an entirely new one.
Such CDK behavior necessitated meticulous planning from developers. If you already have a resource that you need to “check out” into your IaC and then update it, then you need to use Custom Resource, which significantly complicates the update process, and so on and so forth.
This has damaged a lot of mental health for every developer trying to manage and scale their cloud infrastructure efficiently. But it was not SST’s fault. These were faults inherited from AWS CDK and CloudFormation.
> So what SST decided to do is that they ditched AWS CDK and jumped from templates-driven IaC to [API-driven](https://5ly.co/custom-api-development/) IaC. This meant that the resources on the lower level were created by AWS SDK and managed by SST instead of Cloudformation.
For this, they found out that Pulumi which uses Terraform Providers (because it uses [Pulumi Classic](https://www.pulumi.com/registry/packages/aws/)) is the best option.
---
## How SST 3 Ion Will Work?
Below, you can see a piece of the [new SST bucket construct](https://github.com/sst/ion/blob/prodution/pkg/platform/src/components/aws/bucket.ts). Just compare the [previous](https://github.com/sst/sst/blob/master/packages/sst/src/constructs/Bucket.ts) bucket construct with a new one: you may notice right away the imports from Pulumi. It means the whole deployment process will be built on Pulumi now.
With the integration of Pulumi, SST now supports all of the [Pulumi packages](https://www.pulumi.com/registry/), which opens up a vast array of new capabilities and integrations previously unavailable in the older versions that relied solely on AWS CDK. This includes access to a wide range of Pulumi's own components, along with a large number of custom components developed by SST itself.
The most radical advancement is that they can support other clouds as well now! SST now includes support for providers beyond AWS, such as Azure, Google Cloud, and even niche providers like Cloudflare, for which SST has already created a number of specialized components. This capability, known as providers in Pulumi's terminology, allows SST to operate across different cloud platforms seamlessly.
That’s not everything! One of the most groundbreaking features introduced with the move to Pulumi is the ability to link resources from one cloud provider to resources from another. This cross-provider linking eases the creation of multi-cloud infrastructure as code (IaC), so that you can manage and orchestrate your applications across multiple cloud environments using SST's enhanced and user-friendly API.
---
## Should I Switch to Ion or Stay with SST v2?
So, my advice is the following: if you already have an old SST codebase - switching to Ion will not be a trivial task. The underlying architecture changed so radically that we are talking about two different libraries here. It will require a careful consideration of how much effort it can be and how to avoid downtimes.
However, if you have a brand new project, then surely you should start with SST 3 Ion: the benefits of adopting this platform are clear and significant. While the SST 3 Ion is not officially stable yet I don’t think it will be an exaggeration to say that we are one inch from there. The [creators of SST](https://x.com/thdxr) are very public and well-known on X/Twitter, and it drives them to do their best to fix bugs very fast. Thus, you can join their official [Discord](https://discord.gg/sst) - in my opinion, some of the bugs could be resolved in a couple of days.
Also, if you need expert guidance or hands-on assistance with your cloud projects, Fively cloud specialists are here to help. Whether implementing a new project with SST 3 Ion or transitioning from an older system, our team can provide the support and expertise necessary to ensure your project’s success.

This is no longer just a thought experiment—it's a reality with tokenization. This innovative approach is transforming how we interact with traditional financial assets by breaking them down into smaller, more accessible pieces. This means even those with smaller budgets can invest in assets previously considered out of reach.
A standout example of this transformation in action is BlackRock's BUIDL, a tokenized treasury fund launched in March 2020. Within just its first month, BUIDL attracted nearly $300 million in investments, showcasing the significant interest and trust in tokenized products. BlackRock's move is a clear signal that the financial markets are evolving, with tokenization at the forefront of this change.
**Why Everyone's Talking About Tokenized Assets**
The tokenization market, although valued at $7.5 billion, is rapidly expanding. Experts from the Boston Consulting Group predict that by 2030, this market could skyrocket to $16 trillion. Here’s why this growth is not just impressive but also important:
- **Increased Liquidity:** Tokenization offers investors the ability to buy and sell portions of assets that were previously difficult to divide or trade.
- **24/7 Markets:** Unlike traditional markets, tokenized assets can be traded around the clock, offering more flexibility and access.
- **Democratized Investments:** More people can now afford to invest in high-value assets, democratizing access to wealth accumulation.
Consider the case of PAXG, a tokenized gold asset. Amid geopolitical tensions in April 2024, its value jumped 20% in just a day. This reaction was not only a testament to tokenized assets' market responsiveness but also highlighted how they adhere to traditional investment safety principles while offering new speculative opportunities.
**Embracing Autonomy with BYOW (Bring Your Own Wallet)**
The concept of "Bring Your Own Wallet" (BYOW) is revolutionizing asset management by shifting control from institutions to individuals. This means investors can manage and access their assets without traditional intermediaries, leading to faster transactions and greater transparency.
Are you ready to manage your investments from the palm of your hand? Here’s how BYOW is changing the game:
- **Self-Custody:** Investors hold and control their assets, reducing reliance on banks and brokers.
- **Immediate Transactions:** Trades and transfers can occur instantly, without the delays of traditional banking.
**What’s Next for Financial Markets?**
As the integration of traditional and digital finance continues, the benefits of tokenization are becoming more evident. This blending of worlds is not just about new technology—it's about reshaping investor expectations and democratizing access to financial opportunities. Blockchain jobs, particularly for those skilled in blockchain consulting jobs and blockchain developer jobs, are booming as companies seek to leverage these new opportunities.
Asset managers are now exploring ways to incorporate these strategies to tap into new sources of liquidity and potentially arbitrage between on-chain and off-chain markets. This evolution is not just technological, but a fundamental shift in how we think about and engage with assets.
**A New Era for Investors and Innovators**
The shift towards tokenization is not just inevitable; it's already happening. It's a thrilling time for investors, especially for those equipped to navigate this new landscape. We at [Calyptus](https://calyptus.co/), stand at the intersection of education, hiring, and blockchain, this presents us with a unique opportunity to empower engineers and developers with the skills needed to thrive in this new era. With remote blockchain jobs expanding, the sector is ripe with opportunities for both seasoned and entry-level blockchain jobs.
Whether you're a seasoned investor or a curious newcomer, the tokenization of assets offers a world of opportunities. How will you leverage these changes to reshape your financial future?

1,886,786 | Why I Choose WebStorm Over VSCode | As a front-end developer with four years of experience, I've often found myself as the odd one out in... | 0 | 2024-06-13T10:08:07 | https://dev.to/haikelei/why-i-choose-webstorm-over-vscode-3flj | webdev, vscode, programming, devops | As a front-end developer with four years of experience, I've often found myself as the odd one out in my team for my choice of IDE. While the majority of my colleagues surf the waves of Visual Studio Code (VSCode), I remain steadfastly committed to WebStorm. This decision is not a matter of stubbornness or resistance to change but is rooted in a decade-long journey of software development that has shaped my preferences and workflows.
## A Decade with JetBrains IDEs
My journey with JetBrains products began long before I delved into front-end development. From 2015 to 2021, I utilized Android Studio for developing Android applications. In the realm of Android development, it remains the top choice even today, and my preference was established during that period.
Over the next two years, I ventured into backend and frontend development. For Java programming, IntelliJ IDEA was my first and unquestionable choice. However, in the frontend arena, while most of my colleagues use VSCode, my experiences have instilled in me a profound appreciation for the interaction design and feature set of JetBrains IDEs.
As a result, I use WebStorm for developing frontend projects.
Here are the key reasons why I continue to choose WebStorm over VSCode:
### 1. Seamless Transition from IDEA Products
Having spent six years immersed in the JetBrains ecosystem, switching to WebStorm was a natural progression. The familiarity with the interface, shortcuts, and overall design significantly reduced the learning curve. The muscle memory and workflow efficiency I've developed over the years transferred seamlessly to WebStorm, allowing me to focus on coding rather than relearning an IDE.
### 2. Robust Out-of-the-Box Features
One of the standout features of WebStorm is its comprehensive set of tools and features available right out of the box. Unlike VSCode, which relies heavily on extensions to achieve similar functionality, WebStorm provides a robust environment that includes:
- Advanced JavaScript and TypeScript support
- Comprehensive code refactoring tools
- Built-in debugging and testing tools
- Seamless integration with version control systems
- Excellent support for modern frameworks like React, Angular, and Vue.js
These features significantly enhance productivity and reduce the need to hunt for and manage multiple extensions.
### 3. Superior Code Analysis and Refactoring
WebStorm excels in code analysis and refactoring capabilities. The IDE provides intelligent code completion, on-the-fly error detection, and powerful refactoring tools that are a cut above what VSCode offers through its extensions. This level of code insight is invaluable for maintaining high code quality and accelerating development.
### 4. Integrated Development Tools
WebStorm's integration with build tools, task runners, and package managers is seamless. Whether it's Webpack, Gulp, npm, or Yarn, WebStorm handles these integrations with ease. The built-in terminal, database tools, and REST client further consolidate the development environment, making it a one-stop shop for all development needs.
### 5. Consistent Updates and Support
JetBrains is known for its regular updates and excellent support. WebStorm receives frequent updates that bring new features, improvements, and bug fixes. The active community and responsive support team ensure that any issues are quickly addressed, providing a stable and reliable development environment.
## Conclusion
While VSCode is undeniably a powerful and popular IDE, my preference for WebStorm is deeply rooted in my extensive experience with JetBrains products. The seamless transition, robust out-of-the-box features, superior code analysis, integrated development tools, and consistent updates make WebStorm the ideal choice for my development needs.
That said, I remain open to using VSCode if the need arises. For now, WebStorm satisfies all my work requirements and aligns perfectly with my workflow, giving me no compelling reason to switch. By sticking with WebStorm, I can leverage a decade's worth of familiarity and efficiency, enabling me to focus on what I do best—writing high-quality code. | haikelei |

It is crucial that programmers understand data types and how they can be converted. This will help them to avoid unforeseen errors, and ensure that codes are easier to maintain and are more reliable.
## Data types in JavaScript
There are two major data types in JavaScript. They are;
1. Primitive data types and;
I. Number
II. String
III. Boolean
IV. Undefined
V. Null
VI. Symbol
VII. bigInt
2. Non-primitive or object types
I. Objects
II. Arrays
III. Functions
## What is data type conversion?
Data type conversion means changing the data type of a JavaScript value. There are two ways of changing data types in JavaScript; one way is when the programmer manually converts the data type of a value. This is also known as type casting or explicit data conversion. The second approach to data type conversion is performed automatically by the compiler, usually done when operations or comparisons involves more than one data type. This is known as type coercion or implicit data conversion.
## Explicit data conversion:
Sometimes, to avoid unexpected result or to ensure that the outcome of a program is outputted in the correct data type, programmers can manually convert data from one type to another in JavaScript.
## Converting values to number:
To convert a data type to number,
Use Number() method.
Eg.
```
Let example1 = “456”;
Number(example1); // 456
```
The Number() method converts numeric strings to the number in the string.
```
let example2 = "i am a number";
Number(example2) // NaN
```
The Number() method converts text strings to NaN (not a number).
```
let example3 = true;
Number(example3) //1
let example4 = false;
Number(example4) //0
let example5 = null;
Number(example5); // 0
let example6;
typeof example6 // 'undefined'
Number(example6) // NaN
```
The Number() method converts Booleans to 1 and 0. 1 for true, and 0 for false. It also converts null to 0 and undefined to NaN.
Other methods for number type conversions include
parseInt(); returns an integer.
parseFloat(); returns a floating number.
## Converting values to string:
To convert data types to string, use the String() or toString() methods.
Examples:
```
Let example1 = 1234;
String(example1) // ‘1234’
Let example2 = true;
example2.toString() // ‘true’
let example3;
String(example3) // “undefined”
let example = 3+4;
String(example)
'7'
example
7
```
Parsing the values into the String() function converts the outcome into a string.
## Converting values to Boolean:
Boolean represent true or false values. In converting other data types to Boolean, these are some of the rules.
Numbers other than 0 converts to true;
```
Boolean(-10) // true
Boolean(10) //true
```
Number 0 converts to false;
```
Boolean(0) // false
```
Undefined values convert to false;
```
Let x;
Boolean(x); // false
```
Null converts to false;
```
Boolean(null) // false
```
Empty strings converts to false;
```
Boolean("") // false
```
Strings with numbers or text inside converts to true.
```
Boolean("0") // true
Boolean("text") // true
```
## Implicit Data Conversion.
JavaScript is a dynamically typed language. This means that the language does not require programmers to specify data types as variables are declared. Instead, JavaScript automatically determines the data types of the values. A proper understanding of how JavaScript does this is important to programmers for writing maintainable and reliable code. Some of the applicable rules in JavaScript type coercion include;
• Plus sign operator (+) combined with a string is treated as a concatenation sign.
```
10 + "10" // “1010”
10 + "example" // '10example'
true + " example" // 'true example'
```
• Combining numbers with operators (-, *, /, %) will convert the outcome to number.
```
10 - "10" // 0
10 – true // 9
10 * false // 0
10/undefined // NaN
10-null // 10
10 % "10" // 0
10 % "sample text" // NaN
10 - "sample text" // NaN
```
• Logical operations (&&, ||, !), converts values to Boolean based on their truthy or falsy equivalence.
In logical operations (&&, ||, !), the conversion follows a truthy and falsy hierarchy:
a) Numbers apart from 0, non-empty strings, and objects are considered truthy.
b) Zero, empty strings, null, undefined, NaN, and false are considered falsy.
c) Values are implicitly converted based on this hierarchy (e.g., "" || true evaluates to true).
## conclusion
Programmers should take note of how JavaScript converts data implicitly so as to avoid surprises should the outcomes present itself in your code. Explicit conversion methods should be used to ascertain what data types the outcomes will be.
Programmers should also note that when comparing values, strict equality operator ( === ) should be their preference. === checks for both equality of the value and the data types. Whereas with == operator, only values are checked. Hence, “10” == 10 will evaluate as true but if the data types were checked, they are not equal as one is a string and the other is a number.

Luckily, we can define our own matcher to ignore these irrelevant details. Also makes the spec read better. :)
```rb

In... | 0 | 2024-06-13T10:03:21 | https://dev.to/novita_ai/all-you-need-to-know-about-automatic-chain-of-thought-prompting-in-large-language-models-56ic | llm | ## Introduction
What is automatic Chain of Thought Prompting in large language models? In this blog, we will break this question into small pieces, starting from the definition of Chain of Thought (CoT) Prompting, to the advantages and development of Auto CoT. Finally, we will discuss [**LLM API**](https://novita.ai/reference/llm/llm.html) as being a core part of applying Auto CoT. Stay tuned to explore the powerful Auto CoT!
## What Is CoT Prompting?
Chain-of-Thought (CoT) Prompting is a technique used to enhance the reasoning capabilities of large language models (LLMs). LLMs, such as GPT-3, have shown remarkable performance on a variety of tasks, including question-answering, text generation, and problem-solving.
However, in many complex reasoning tasks, LLMs may struggle to provide a complete and coherent step-by-step solution. CoT Prompting aims to address this by eliciting the language model to generate a "chain of thought" - a sequence of intermediate reasoning steps that lead to the final answer.
The core idea behind CoT Prompting is to prompt the language model to explicitly think through a problem, rather than just providing a direct answer. This is typically done by including a prompt like "Let's think through this step-by-step" or "Explain your reasoning" alongside the input question or problem. CoT Prompting can lead to more accurate and explainable outputs, particularly for complex, multi-step tasks.
## Why Do We Need Auto CoT?
The key issue is that there are two main approaches to chain-of-thought (CoT) prompting, and both have significant drawbacks.
### Limitations of Zero-Shot-CoT
In this approach, you simply give the language model (LM) a question and ask it to "think step-by-step" to arrive at the answer. The advantage is that it's very easy to use - you don't need to provide any additional information or examples. However, the big downside is that the LM's step-by-step reasoning can often be flawed or contain mistakes. So the final answer may not be reliable.
### Limitations of Manual-CoT
This approach involves manually creating detailed examples for the LM, showing it how to break down a problem into logical steps and arrive at the correct answer. By providing these carefully crafted examples, the LM can then use that knowledge to better solve new questions. The benefit is that the LM's reasoning is more robust and accurate when it can refer to the manual examples. But the major drawback is that creating these detailed examples is extremely time-consuming and requires a lot of human effort and expertise. It's not scalable at all.
### Overcoming Limitations with Auto-CoT
So in summary, Zero-Shot-CoT is easy but unreliable, while Manual-CoT is more robust but very labor-intensive. This is the key challenge the authors are trying to address with their proposed "Auto-CoT" approach.
The core idea of Auto-CoT advocated by some scholars is to automatically generate the example demonstrations that the LM can use, without requiring manual human effort. This could potentially combine the benefits of both the existing approaches - reliable reasoning, but in a more scalable way.
## How did people develop Auto CoT?
In this section, we are going to explore the details of the paper titled "Automatic Chain of Thought Prompting in Large Language Models" by Zhuosheng Zhang, Aston Zhang, Mu Li, and Alex Smola published in 2022. If you are not interested in research details, feel free to skip to the next section.
### Proposed Approach
To overcome these limitations of existing CoT approaches, the authors propose an "Auto-CoT" paradigm that automatically constructs demonstrations for CoT prompting.
The key steps are:
1. Leveraging LLMs with the "Let's think step by step" prompt to generate reasoning chains for demonstration questions.
2. Recognizing that the generated reasoning chains may contain mistakes, the authors focus on ensuring diversity in the selected demonstration questions.
3. The authors develop a two-step approach to automatically construct demonstrations:
a. Partition the dataset questions into clusters based on similarity.
b. Select a representative question from each cluster and generate its reasoning chain using Zero-Shot-CoT.
### Evaluation
The authors evaluate the Auto-CoT approach with GPT-3 on ten benchmark reasoning tasks, including arithmetic, commonsense, and symbolic reasoning. They compare the performance against the Zero-Shot-CoT and Manual-CoT paradigms.
### Key Findings
The results show that the Auto-CoT approach consistently matches or exceeds the performance of the Manual-CoT paradigm, which requires manual design of demonstrations. This demonstrates that LLMs can perform effective CoT reasoning without the need for manual efforts.
## How Does Auto CoT Work?
The key idea behind Auto-CoT is to automatically generate the demonstration examples that the language model (LM) can use for chain-of-thought (CoT) prompting, rather than relying on manually crafted demonstrations.
Here's how the Auto-CoT approach works, step-by-step:
**Step 1** Question Clustering:
- The first step is to take the set of test questions (the questions the LM will be evaluated on & pre-existing questions from the standard benchmark datasets) and group them into a few clusters based on their similarity.
- This clustering helps ensure the demonstration questions cover diverse types of problems, rather than being too similar.
**Step 2** Demonstration Generation:
- For each cluster of questions, Auto-CoT selects a representative question from that cluster.
- It then uses the "Let's think step-by-step" prompt to ask the LM to generate a reasoning chain for that representative question.
This reasoning chain, consisting of the intermediate steps and the final answer, becomes the demonstration example for that cluster.
**Step 3** Prompting the LM:
- When evaluating the LM on a new test question, Auto-CoT provides the LM with the set of automatically generated demonstration examples.
- The LM can then use these demonstrations to guide its own step-by-step reasoning process to arrive at the answer for the test question.
## How Can I Use Auto CoT?
### Requirements:
- Python version 3.8 or later
### Installation:

This time, it’s not... | 0 | 2024-06-13T10:00:05 | https://dev.to/systemglitch/goyave-v5-the-reborn-rest-framework-aims-higher-30c7 | go, news, webdev, opensource | Over two years in the making, Goyave’s next major release is finally available. This time, it’s not just about a breaking change: the framework has been entirely redesigned and rewritten. Let’s talk about this rebirth and what it entails.
## But first, what is Goyave?
Goyave is an **opinionated REST API framework** for the **Go** programming language. Its initial goal was to make backend development easier and concise so applications can be developed fast and cleanly. Using the framework would allow developers to **focus on their business logic** rather than technical aspects. Despite being filled with powerful tools, it tried to stay as accessible as possible.
That’s a bit too much isn’t it? Indeed, there were contradictions in the design, leading to many shortcomings. Ultimately, the framework failed to deliver on its most important promises. Each of its features both contributed positively to one of the principles while negatively impacting another.
With v5, the design is **refocused** and takes some important new directions.
## New direction
Goyave has new commitments that are now fully assumed. The first is the target: instead of trying to please everyone and suit every need from prototype to real application, the framework now focuses on **medium to large enterprise projects with real-world constraints**.
The architecture recommendations and related utilities are taken one step further to eliminate dependency coupling, make testing easier, and streamline the development process.
Conciseness is not an absolute requirement anymore, making programs and syntax a bit more verbose, but way more flexible. In other words, the “progressive” aspect is abandoned in favor of a more “clean code” oriented approach, trading simplicity for scalability.
## Introducing v5
v5 is an almost entire **rewrite** of the framework containing all the accumulated ideas for rework and improvements that would introduce breaking changes. This new major version not only aims at fixing the outstanding issues and design flaws, but also improves on existing features by upgrading them to the latest available technology. Expect v5 to feel modern and to neatly integrate with all the new language features such as generics, file systems, structured logging, and more.
This new release is way too large to be discussed in detail here. If you are interested, feel free to read the official [changelog](https://goyave.dev/changelog/v5.0.0.html).
## Building a community
Despite several production applications made and running with it, the framework still has a relatively small community. More efforts will be made to gather and take care of a **growing and strong community**, which is very important for open-source projects.
You can help! Join the [Discord server](https://discord.gg/mfemDMc), give your feedback on [Github](https://github.com/go-goyave/goyave) discussions, create issues, share this article. All contributions are welcome and very valuable.
If you feel like it, you can even help develop the framework further by opening a Pull Request. Plenty of good first issues are available to get you started.

1,884,209 | How Layouts Work in Rails | This article was originally published in Rails Designer. Layouts in Rails have been around since... | 0 | 2024-06-13T10:00:00 | https://railsdesigner.com/rails-layouts/ | rails, ruby, webdev | This article was originally published in [Rails Designer](https://railsdesigner.com/rails-layouts/).
---
Layouts in Rails have been around since the earlier versions. They define the surrounding HTML structure shared by multiple views, allowing you to implement a consistent visual design. They encapsulate shared site elements like partials and [ViewComponent](https://railsdesigner.com/what-is-view-component/) like: headers, footers, and navigation bars. This allows you have a consistent “chrome” for every view of your app, but also have invisible elements added onto every page, like JavaScript snippets.
Most Rails developers easily grasp the idea of layouts, but not all know the inner workings of layouts in Rails. Let's go over the most important parts.
## How content is rendered in layouts
The central mechanism in layouts for embedding view-specific content is the `yield` method. When you define a layout, whether it's app-wide in `application.html.erb` or specifically for other controllers, `yield` marks the spot where content from individual view templates (`show.html.erb`, `index.html.erb`, etc.) will be inserted into the layout.
A typical layout might look like this:
```ruby
<!DOCTYPE html>
<html>
<head>
<title>Rails Designer</title>
</head>
<body>
<header>
<h1>Welcome to Rails Designer</h1>
</header>
<%= yield %>
<footer>
<p>© 2024 Rails Designer</p>
</footer>
</body>
</html>
```
In this layout, `<%= yield %>` is where Rails inserts the content of other templates based on the action being executed.
## How Rails looks up layouts
By default Rails looks for layouts in the `app/views/layouts` folder. The actual layout is checked in the following steps.
In your controller you can specify a layout:
```ruby
class AuthorsController < ApplicationController
layout "writers"
# …
end
```
Rails will check `app/views/layouts` for `writers.html.erb` file.
If no `layout` declaration was set in above controller, Rails uses the controller name to look for a `authors.html.erb` layout. If it cannot find a controller-specific layout, it will fallback to the default `application.html.erb`.
The `layout` declaration takes more than just a string or symbol though. You can also pass `false` to skip wrapping the view in a layout. Or you can pass a method with a conditional:
```ruby
class AuthorsController < ApplicationController
layout :authors_layout
# …
private
def authors_layout
Current.user.admin? ? "admins" : "authors"
end
end
```
You can also pass the `only` and `except` options to the `layout` declaration: `layout :authors_layout, only: %w[index]`.
Layouts also cascade downward in the hierarchy. So with the following controller:
```ruby
class Authors::BiographiesController < AuthorsController
def show
end
end
```
The `show` view will also use the layout from the `authors_layout` method.
Are you using [Devise](https://github.com/heartcombo/devise)? If you create a `app/views/layouts/devise.html.erb` layout, that layout is used for your signin and signup views. 💡
## Nested layouts
Rails doesn't come with nested layouts out-of-the-box. If you are familiar with Static Site Generators you might have used them. I often use a nested layout for my SaaS' settings page. It often features a dedicated navigation for the many settings.
The cleanest solution, and the one I use in my Rails apps, works like this:
1. Set the layout in the controller:
```ruby
# app/controllers/settings_controller.rb
class SettingsController < ApplicationController
layout "settings"
end
```
All separate settings screens inherit from this controller, eg. `Settings::TeamsController < SettingsController`.
2. Create a settings-layout:
```ruby
# app/views/layouts/settings.html.erb
<div class="md:h-screen grid grid-cols-12 gap-4 md:gap-2 lg:gap-8">
<%= component "navigation/settings", account: Current.account %>
<div class="col-span-12 md:col-span-8 lg:col-span-9">
<%= yield %>
</div>
</div>
<% parent_layout "application" %>
```
You can add whatever component/html you need here. Make sure to include the `yield` method!
3. Create a `parent_layout` helper
This helper is the important part that makes it nested layouts work.
```ruby
# app/helpers/layouts_helper.rb
module LayoutsHelper
def parent_layout(layout)
@view_flow.set(:layout, output_buffer)
output = render(template: "layouts/#{layout}")
self.output_buffer = ActionView::OutputBuffer.new(output)
end
end
```
It saves the current output, renders the specified parent layout, and then sets this rendered output as the new output buffer to encapsulate nested layouts. That's all there's needed for nested layouts.

1,886,779 | The Benefits of Agile Cloud Transformation for Complex Organizations | In today's rapidly evolving business landscape, organizations are increasingly recognizing the need... | 0 | 2024-06-13T09:58:46 | https://dev.to/wednesdaysol/the-benefits-of-agile-cloud-transformation-for-complex-organizations-2pch | 
In today's rapidly evolving business landscape, organizations are increasingly recognizing the need for agility and adaptability to stay ahead of the competition and drive innovation. This has led to a growing emphasis on cloud transformation as a means to streamline processes, improve productivity, and enhance customer experiences. However, for complex organizations with intricate systems and structures, embarking on a cloud transformation journey can be particularly challenging. In this article, we will explore the benefits of agile cloud transformation for complex organizations and delve into the key considerations and strategies for success.
## Understanding Organizations as Complex Systems
Complex organizations are characterized by interconnectedness, interdependencies, and dynamic interactions between various components such as people, processes, technology, and culture. These systems are often characterized by non-linear relationships, where small changes can potentially have significant ripple effects throughout the organization. Understanding this complexity is crucial when embarking on a cloud transformation journey.
When we delve deeper into the concept of organizations as complex systems, we realize that they are like intricate webs, where every strand is interconnected and influences the overall functioning of the organization. People, as the driving force behind these systems, bring their unique perspectives, skills, and experiences to the table. Their interactions, collaborations, and decision-making processes shape the organization's culture and determine its success.
Moreover, technology plays a vital role in modern organizations. It acts as an enabler, providing tools and platforms that streamline processes, enhance communication, and drive innovation. From enterprise resource planning (ERP) systems to customer relationship management (CRM) software, technology solutions have become indispensable in today's digital age.
## The Interplay of People and Technology in Organizations
The success of any cloud transformation initiative lies in the seamless interplay between people and technology. While the implementation of cutting-edge cloud solutions can enable organizations to optimize their operations and drive innovation, it is essential to involve all stakeholders throughout the process. This includes employees, leaders, and external partners who can provide valuable insights and expertise to ensure a successful transition.
When organizations embark on a cloud transformation journey, it is crucial to consider the human aspect. People are not merely passive recipients of technology; they are active participants who need to be engaged, trained, and empowered. Change management becomes a critical component, as employees may experience resistance or fear due to the uncertainty that comes with adopting new technologies.
Effective communication and collaboration between IT teams and end-users are vital to ensure that technology solutions align with the organization's goals and meet the needs of its workforce. By involving employees in the decision-making process and providing them with the necessary training and support, organizations can foster a culture of innovation and adaptability.
## Navigating the Complexity of Modern Organizations
Modern organizations are faced with an array of complexities, ranging from legacy systems and multiple stakeholders to regulatory requirements and changing market dynamics. Agile cloud transformation acknowledges and addresses these complexities by adopting an iterative and adaptive approach. Rather than pursuing a one-size-fits-all strategy, organizations can leverage agile methodologies to navigate the intricacies and uncertainties that come with transforming their systems and processes.
Legacy systems, often deeply ingrained in an organization's infrastructure, can pose challenges during cloud transformation. These systems may have outdated technologies, limited scalability, and compatibility issues. However, by adopting an agile mindset, organizations can break down the transformation process into smaller, manageable tasks. This approach allows for continuous learning, feedback, and adjustments, ensuring that the organization remains responsive to evolving needs and emerging technologies.
Furthermore, modern organizations operate in dynamic environments influenced by various stakeholders, including customers, suppliers, regulators, and competitors. Each stakeholder brings their own set of expectations, requirements, and constraints. By embracing an agile approach, organizations can adapt their cloud transformation strategies to accommodate the diverse needs of these stakeholders, fostering stronger relationships and enhancing overall organizational performance.
Regulatory requirements and compliance also add complexity to the cloud transformation journey. Organizations must navigate a complex landscape of data privacy laws, industry-specific regulations, and security standards. By adopting an agile approach, organizations can ensure that they stay up-to-date with changing regulations and proactively address any compliance-related challenges.
Organizations are complex systems that require a deep understanding of their interconnectedness and dynamics. Cloud transformation, when approached with an agile mindset, can help organizations navigate these complexities, optimize their operations, and drive innovation. By recognizing the interplay between people and technology, involving all stakeholders, and adapting to the intricacies of modern organizations, successful cloud transformations can be achieved.
## Navigating the Cloud Transformation Journey
Embarking on a cloud transformation journey requires careful planning and execution. Without a clear roadmap and a comprehensive understanding of the organization's unique requirements, organizations risk encountering various challenges and roadblocks along the way. To ensure a smooth transition, organizations must consider several key factors.
One of the critical considerations in cloud transformation is the alignment between business goals and cloud strategy. Organizations should evaluate their existing systems, identify areas that can benefit from cloud adoption, and define clear objectives. By aligning cloud initiatives with the strategic priorities of the organization, stakeholders can better understand the value and impact of the transformation.
Furthermore, organizations need to assess their current infrastructure and determine the readiness for cloud adoption. This involves evaluating the existing hardware, software, and network capabilities to ensure compatibility with cloud services. By conducting a thorough assessment, organizations can identify potential gaps and plan for necessary upgrades or modifications to facilitate a seamless transition.
Another critical consideration is the assessment of security and compliance requirements. Cloud transformation often involves migrating sensitive data and applications to the cloud, necessitating robust security measures. Organizations should carefully evaluate cloud service providers' security capabilities and ensure compliance with industry regulations to protect data and maintain business continuity.
Moreover, organizations should consider the impact of cloud transformation on their workforce. It is essential to provide adequate training and support to employees to ensure a smooth transition. By investing in training programs and fostering a culture of continuous learning, organizations can empower their employees to embrace the change and maximize the benefits of cloud technology.
## Strategies for Evolving Your Cloud Infrastructure
Transitioning to the cloud is not a one-time event but an ongoing process of evolution and optimization. Organizations should adopt a phased approach to cloud transformation, prioritizing critical workloads and applications. By gradually migrating systems to the cloud and leveraging hybrid cloud models, organizations can minimize disruptions, manage risks effectively, and gain valuable insights to inform future migration efforts.
In addition to a phased approach, organizations should also consider the scalability and flexibility of their cloud infrastructure. Cloud technology offers the opportunity to scale resources up or down based on demand, allowing organizations to optimize costs and improve operational efficiency. By leveraging auto-scaling capabilities and implementing elastic infrastructure, organizations can ensure their cloud environment can handle fluctuations in workload without compromising performance.
Furthermore, organizations should embrace automation and DevOps practices to streamline cloud operations and enhance agility. By automating routine tasks, organizations can free up resources and focus on more strategic initiatives. Additionally, implementing DevOps principles, such as continuous integration and continuous deployment, can accelerate the delivery of applications and services, enabling organizations to respond quickly to changing business needs.
Lastly, organizations should prioritize data management and governance in their cloud transformation journey. With the increasing volume and complexity of data, it is crucial to have a robust data management strategy in place. This includes defining data ownership, implementing data classification and protection measures, and establishing data governance frameworks. By effectively managing data in the cloud, organizations can ensure data integrity, compliance, and accessibility.
## Unlocking Success in Digital Transformation
Cloud transformation is an integral part of broader digital transformation initiatives. The digital era demands organizations to embrace agility, customer-centricity, and innovation to thrive in a fast-paced and interconnected world. While adopting cloud technologies can provide the foundation for digital transformation, to truly unlock success, organizations must address several essential factors.
## Essential Factors for a Successful Digital Transformation
First and foremost, a clear digital strategy is crucial. Organizations must define their digital vision, set clear goals, and develop a roadmap that aligns technology initiatives with broader business objectives. This strategy should consider the organization's strengths, weaknesses, opportunities, and threats and identify areas where digital capabilities can create a competitive advantage.
Additionally, organizations need to prioritize building a culture of innovation. This involves fostering an environment that encourages creativity, risk-taking, and continuous learning. By empowering employees to think outside the box and experiment with new ideas, organizations can drive transformative change and stay ahead of the competition.
Furthermore, effective leadership is vital for successful digital transformation. Leaders must champion the digital agenda, communicate the vision, and inspire employees to embrace change. They should also provide the necessary resources, support, and guidance to ensure the smooth execution of digital initiatives. With strong leadership, organizations can navigate the complexities of digital transformation and drive meaningful outcomes.
## Embracing Agile Methodologies for Transformational Success
Agile methodologies have revolutionized software development, enabling organizations to deliver value incrementally, adapt to changing requirements, and foster collaboration across teams.
