The Number of Beautiful Subsets
Medium
You are given an array nums of positive integers and a positive integer k.
A subset of nums is beautiful if it does not contain two integers with an absolute difference equal to k.
Return the number of non-empty beautiful subsets of the array nums.
A subset of nums is an array that can be obtained by deleting some (possibly none) elements from nums. Two subsets are different if and only if the chosen indices to delete are different.
**Example 1:**
- **Input:** nums = [2,4,6], k = 2
- **Output:** 4
- **Explanation:** The beautiful subsets of the array nums are: [2], [4], [6], [2, 6].
It can be proved that there are only 4 beautiful subsets in the array [2,4,6].
**Example 2:**
- **Input:** nums = [1], k = 1
- **Output:** 1
- **Explanation:** The beautiful subset of the array nums is [1].
It can be proved that there is only 1 beautiful subset in the array [1].
**Example 3:**
- **Input:** nums = [4,2,5,9,10,3], k = 1
- **Output:** 23
**Constraints:**
- <code>1 <= nums.length <= 20</code>
- <code>1 <= nums[i], k <= 1000</code>
**Solution:**
```
class Solution {
/**
* @param Integer[] $nums
* @param Integer $k
* @return Integer
*/
function beautifulSubsets($nums, $k) {
$countBeautifulSubsets = -1;
$countNums = array_fill(0, 1010, 0);
$size = count($nums);
$dfs = function($index) use (&$dfs, &$countBeautifulSubsets, &$nums, &$countNums, $size, $k) {
if ($index >= $size) {
++$countBeautifulSubsets;
return;
}
$dfs($index + 1);
$isBeautifulIncrement = $nums[$index] + $k >= 1010 || $countNums[$nums[$index] + $k] == 0;
$isBeautifulDecrement = $nums[$index] - $k < 0 || $countNums[$nums[$index] - $k] == 0;
if ($isBeautifulIncrement && $isBeautifulDecrement) {
++$countNums[$nums[$index]];
$dfs($index + 1);
--$countNums[$nums[$index]];
}
};
$dfs(0);
return $countBeautifulSubsets;
}
}

TypeScript has given the frontend a powerful chance to deliver reliable and maintainable code. The more you correctly type your code, the more you fall into its strengths and importance. In this post, I'll mention some TypeScript tips that you may or may not know about.
## How TypeScript works?
The first thing you should know is **how TypeScript works**?
<figure style={{ textAlign: "center" }}>
<figcaption>
[Source](https://gist.github.com/zeyadetman/e2435ca1e2e0fe78d3dc981250e42499)

Browsers are designed to only understand JavaScript, just as computers are designed to only understand zeros and ones. In the case of computers, we compile high-level code to machine code and then to zeros and ones so the computer can understand it. Similarly, we transpile or translate TypeScript code to JavaScript code to be understood by browsers and other engines that only know JavaScript.
To do this, we may use the popular `tsc` tool, You can also check out the [awesome-typescript-compilers](https://github.com/JohnDeved/awesome-typescript-compilers?tab=readme-ov-file) repository to learn more about them.
For example, code like this:
```ts
type animals = "cat" | "dog";
const getAnimal = (animal: animals) => animal;
getAnimal("cat");
```
Is translated to this JavaScript code, so browsers can understand it:
```js
const getAnimal = (animal) => animal;
getAnimal("cat");
```
**Note: TypeScript code is eliminated in the transpiling process.**
This leads us to an **important conclusion**: once you realize it, you'll notice a lot about TypeScript concepts and why they've been written in their particular way.
**Conclusion: As TypeScript does not run on browsers, it only runs at compile time, not at runtime.**
> **Compile time** is the time when your code is being built, before it runs and becomes interactive. **Run time** is when your code is running and interacting with the client.
### Differences in Action
Let's compare a typed language that checks types at runtime, like C#, with TypeScript, which checks types at compile time:
#### Function overloading
> Some JavaScript functions can be called in a variety of argument counts and types. For example, you might write a function to produce a `Date` that takes either a timestamp (one argument) or a month/day/year specification (three arguments).
> [Resource](https://www.typescriptlang.org/docs/handbook/2/functions.html#function-overloads)
In C#, we can achieve function overloading by declaring multiple function arguments and bodies. This is possible because C# checks the type of the function arguments at runtime and defines the function body accordingly:
```c#
void display() { ... }
void display(int a) { ... }
float display(double a) { ... }
float display(int a, float b) { ... }
```
However, in TypeScript, we go to the runtime without types, without typescript itself, so there's no runtime type checks and then we can't assign multiple values to the same variable in javascript, or in other words we can't create multiple bodies for the same function.
```ts
function makeDate(timestamp: number): Date;
function makeDate(m: number, d: number, y: number): Date;
function makeDate(m: number, d: string, y: number): string;
function makeDate(
mOrTimestamp: number,
d?: number | string,
y?: number
): Date | string {
if (typeof d === "string") {
return "hello";
}
if (d !== undefined && y !== undefined) {
return new Date(y, mOrTimestamp, d);
} else {
return new Date(mOrTimestamp);
}
}
const d1 = makeDate(1234);
const d2 = makeDate(5, 5, 5);
```
This will be compiled to this Javascript code:
```js
function makeDate(mOrTimestamp, d, y) {
if (typeof d === "string") {
return "hello";
}
if (d !== undefined && y !== undefined) {
return new Date(y, mOrTimestamp, d);
} else {
return new Date(mOrTimestamp);
}
}
const d1 = makeDate(1234);
const d2 = makeDate(5, 5, 5);
```
There's libraries can do runtime checks for javascript, one of the most popular libraries do this is [zod](https://zod.dev/) you can give it a try.
## Narrowing (make it more specific)
## `keyof` and `typeof`
- `keyof` from its name, used to "extract" a key of a TYPE, and since objects are the only datatype that contains keys, then `keyof` is used to extract key of an object in a **union** format
```ts
type obj = { [n: number]: string };
type A = keyof obj; // number
```
- `typeof` from its name, used to return the `type` of a variable. simple!
```ts
let str = "Alia";
type a = typeof str; // string
const str2 = "Alia";
type b = typeof str2; // "Alia"
```
**Important note: I used `let` here instead of `const`. If I used `const`, then the type would be the specific string value itself.**
Let's merge both
```ts
const obj = {
id: 1,
name: "Alia",
}; // javascript variable no types
type typeOfObj = typeof obj; // type of the javascript object
type keysOfObj = keyof typeOfObj; // id | name
type keysOfObjOneLine = keyof typeof obj;
```
Notice here
- `keyof` extracts keys of type (object).
- `typeof` extracts the type of variable.
_keep this in your mind for the mapped types section._
## `in` operator and `extends`
Similar to the previous section, `in` operator is kinda similar way you can use it to limit the key to be within a group of types
```ts
type keysOfObj = "id" | "name";
type obj = { [key in keysOfObj]: string };
// type obj = {
// id: string;
// name: string;
// }
```
But we need to modify the code to fix the type for the `id` key to be `number` not `string`
- `extends` consider it as `if else` of typescript.
```ts
type keysOfObj = "id" | "name";
type obj = { [key in keysOfObj]: key extends "id" ? number : string };
// That's it
```
_This called mapped types_
## Generics
Think about it as a function in javascript, if you have a type and you're repeating it with slight changes, then you probably need to use `generics`.
```ts
interface BasicType<T> {
input: T;
}
const x: BasicType<string> = { input: "test" };
const y: BasicType<number> = { input: "test" }; // wrong
```
```ts
function basic(a, b) {
return { a, b };
}
function basic<A, B>(a, b) {
return { a, b };
}
function basic<A, B>(a: A, b: B): { a: A; b: B } {
return { a, b };
}
basic<string, number>("hello", 2);
```
we can still use `extends` with generics to give a powerful type.
## Typescript Coverage
In addition to adding TypeScript rules to your project, it's important to track TypeScript code coverage. Code coverage helps identify missing types for variables.
You might think it's obvious if a variable has a type, but when using third-party libraries, classes, or functions, it's easy to miss some. Not everything, such as query parameters, will be tracked by the TypeScript coverage library, but it definitely helps.
I suggest using [typescript-coverage-report](https://www.npmjs.com/package/typescript-coverage-report) for this purpose. If you know of a better option, feel free to share it in the comments below.

However, citizens are in no hurry to use the currency. Why is this happening? Let’s take a closer look at it.
**Chinese Workers Prefer Fiat Money**
The Chinese government is actively trying to introduce a digital yuan. According to the South China Morning Post, some Chinese cities have started paying CBDC to the country’s civil servants. However, a large number of employees are still hesitant to use them for daily transactions and convert them directly into cash.
Sammy Lin, a customer service manager at a Chinese state-owned bank in Suzhou, explains that she does not keep funds in the e-CNY app because it does not charge interest for storage. She also notes that there are currently not many places online or offline where you can use the digital yuan.
Although China has been a “functionally cashless” society for more than a decade, many citizens are still hesitant to use a purely digital currency due to concerns about traceability and limited use cases.
But despite such concerns, according to Yi Gang, former governor of the People’s Bank of China, more than $250 million worth of transactions were made using the digital yuan in July 2023. He also emphasized that the digital yuan is able to “fully protect privacy” due to the so-called “controlled anonymity,” which means that there is no tracking of small payments, but some tracking of large payments is possible.
Charles Hoskinson, the founder of Cardano, emphasizes the importance of cryptocurrency in the modern world. On May 11, he reminded on his social media page that the fundamental concept of cryptocurrency is the creation of new social contracts. Hoskinson emphasized that it is these contracts that will make the government accountable to the people and urged the industry to focus on promoting this goal.
He also warned that anyone who opposes the spread of cryptocurrencies unknowingly supports the concentration of power in the hands of a few.
_“Crypto gives us our voices, financial freedom, and shared humanity back.”_ Hoskinson [remarked](https://x.com/iohk_charles/status/1789403123804688520?s=46&t=aw6ZR-6aD050XLPVXY8AQA).
**European Crypto Industry Development**
The crypto industry is gaining significant growth in Europe. European countries are actively working to create a legal environment to ensure investor protection and financial system stability. For example, Switzerland is known for its “crypto valley” in Zurich, where numerous blockchain companies and startups are based. Malta has adopted a number of laws aimed at regulating cryptocurrencies and ensuring their legality and transparency.
European countries are constantly working on the development of new blockchain solutions and cryptocurrency payment systems. European countries are also actively exploring the possibilities of integrating cryptocurrencies into their financial systems. For example, Switzerland was one of the first countries to [introduce](https://www.bloomberg.com/news/articles/2023-12-06/taxpayers-in-swiss-city-can-settle-bills-with-bitcoin-tether) the possibility of paying taxes in Bitcoin.
Many countries have long accepted cryptocurrency as a means of payment, and Ukraine is no exception. Ukraine is intensively expanding the crypto sphere, attracting investors, startups, and regulators to create a favorable landscape for this spectrum.
Ukrainians have long had the opportunity to pay for purchases in grocery stores using payment solutions from [Corefy](https://corefy.com/en-ua), [Switchere](https://switchere.com/accept-crypto), [Whitepay](https://whitepay.com/), and many others. Moreover, the first cryptocurrency [transaction](https://gncrypto.news/news/ukraines-first-electric-vehicle-purchase-with-crypto/) for the purchase of an electric car has recently taken place in Ukraine. This step demonstrates the significant development and potential of the industry.
**Summary**
The introduction of the digital yuan in China faces a number of challenges, but despite the difficulties, the government continues to promote this initiative. At the same time, the development of the crypto industry in Europe is showing remarkable progress, creating new opportunities for businesses and citizens. The involvement of cryptocurrencies in everyday financial transactions, including charity and shopping, demonstrates the importance of digital assets for economic development. As Charles Hoskinson has aptly noted, the rise of cryptocurrencies is not only shifting financial paradigms, but also has the potential to redefine social contracts and empower people in unprecedented ways. | hryniv_vlad |

The conundrum of containerizing Ollama is that it must be running to pull a model. If you run ollama using `docker compose`, it doesn't provide a way to pull a model from the ollama registry. What's a budding generative AI nerd to do?
The answer is more `docker compose`, as in `docker compose exec`, which runs a script to download a model. Add both commands to a startup script, and you have [autollama](https://github.com/spara/autollama).
```bash

1,863,037 | Building Robust Applications in React with TypeScript and Zod for REST API Validation | When building applications with React and TypeScript, leveraging TypeScript's static typing... | 0 | 2024-05-23T16:54:55 | https://dev.to/schead/building-robust-applications-in-react-with-typescript-and-zod-for-rest-api-validation-cl8 | When building applications with React and TypeScript, leveraging TypeScript's static typing capabilities can significantly enhance your code's reliability. However, even with TypeScript, you can't guarantee the shape and type of data coming from external APIs. This potential discrepancy can lead to runtime errors that disrupt your application's functionality. In this blog post, we'll explore how to handle such situations using Zod, a TypeScript-first schema declaration and validation library.
#### Scenario: Fetching User Data with TypeScript
Imagine you have a React application that fetches user data from an API. The `User` object has a `phoneNumber` property, which is expected to be a string. You'll format this phone number to display it in a user-friendly manner. Here's how you might start:
```tsx
// types.ts
export interface User {
id: number;
name: string;
phoneNumber: string;
}
// api.ts
export const fetchUser = async (userId: number): Promise<User> => {
const response = await fetch(`https://api.example.com/users/${userId}`);
const data: User = await response.json();
return data;
};
// UserComponent.tsx
import React, { useEffect, useState } from 'react';
import { User } from './types';
import { fetchUser } from './api';
const UserComponent: React.FC<{ userId: number }> = ({ userId }) => {
const [user, setUser] = useState<User | null>(null);
const [error, setError] = useState<string | null>(null);
useEffect(() => {
fetchUser(userId)
.then(setUser)
.catch(err => setError(err.message));
}, [userId]);
if (error) return <div>Error: {error}</div>;
if (!user) return <div>Loading...</div>;
const formattedPhoneNumber = formatPhoneNumber(user.phoneNumber);
return (
<div>
<h1>{user.name}</h1>
<p>Phone: {formattedPhoneNumber}</p>
</div>
);
};
const formatPhoneNumber = (phoneNumber: string): string => {
// Logic to format the phone number
return phoneNumber.replace(/(\d{3})(\d{3})(\d{4})/, '($1) $2-$3');
};
export default UserComponent;
```
In this example, we expect `phoneNumber` to be a string. However, if the backend changes `phoneNumber` to a number, this will lead to a runtime error in the `formatPhoneNumber` function.
#### Runtime Error Example
Suppose the backend now sends:
```json
{
"id": 1,
"name": "John Doe",
"phoneNumber": 1234567890
}
```
This change will cause a runtime error in the `formatPhoneNumber` function because `replace` is not a method on numbers. The error will look like this:
```vbnet
TypeError: phoneNumber.replace is not a function
```
This error indicates that `phoneNumber` is not a string as expected, but a number, leading to the failure of the `replace` method.
#### Introducing Zod for Schema Validation
To safeguard against such issues, we can use Zod to validate the data we receive from the API. Here's how we can do it step-by-step:
1. **Install Zod** :
```bash
npm install zod
```
2. **Define a Zod Schema** :
```tsx
// schema.ts
import { z } from 'zod';
export const userSchema = z.object({
id: z.number(),
name: z.string(),
phoneNumber: z.string(),
});
export type User = z.infer<typeof userSchema>;
```
3. **Validate API Response and Provide Feedback** :
```tsx
// api.ts
import { userSchema, User } from './schema';
export const fetchUser = async (userId: number): Promise<User> => {
const response = await fetch(`https://api.example.com/users/${userId}`);
const data = await response.json();
const result = userSchema.safeParse(data);
if (!result.success) {
console.error("Validation Error:", result.error.format());
throw new Error('Invalid data format');
}
return result.data;
};
```
4. **Handle Validation in the Component** :
```tsx
// UserComponent.tsx
import React, { useEffect, useState } from 'react';
import { User } from './schema';
import { fetchUser } from './api';
const UserComponent: React.FC<{ userId: number }> = ({ userId }) => {
const [user, setUser] = useState<User | null>(null);
const [error, setError] = useState<string | null>(null);
useEffect(() => {
fetchUser(userId)
.then(setUser)
.catch(err => setError(err.message));
}, [userId]);
if (error) return <div>Error: {error}</div>;
if (!user) return <div>Loading...</div>;
const formattedPhoneNumber = formatPhoneNumber(user.phoneNumber);
return (
<div>
<h1>{user.name}</h1>
<p>Phone: {formattedPhoneNumber}</p>
</div>
);
};
const formatPhoneNumber = (phoneNumber: string): string => {
// Logic to format the phone number
return phoneNumber.replace(/(\d{3})(\d{3})(\d{4})/, '($1) $2-$3');
};
export default UserComponent;
```
In this updated example, the `fetchUser` function uses the Zod schema to validate the API response. If the data doesn't match the expected schema, an error is thrown, and a detailed validation error is logged to the console. This feedback helps developers quickly identify and resolve issues with the API data.
#### Error Message Example
With the Zod validation in place, if the backend sends the `phoneNumber` as a number, the application will catch this discrepancy and throw an error. The console will log a detailed error message like this:
```css
Validation Error: {
"phoneNumber": {
"_errors": ["Expected string, received number"]
}
}
```
In addition to logging the error, the application will throw an error to the user with the message:
```javascript
Error: Invalid data format
```
This message indicates to the user that there was an issue with the data received from the API.
#### Conclusion
Using Zod for schema validation in your React and TypeScript applications ensures that your application can gracefully handle unexpected changes in the API response structure. This approach helps you catch potential issues early, leading to more robust and reliable applications. By incorporating Zod into your development workflow, you can enhance your application's resilience against API changes and reduce runtime errors.
Remember, while TypeScript provides excellent compile-time type checking, runtime validation with tools like Zod is essential for dealing with external data sources. This combination ensures that your application remains stable and predictable, even when the data it relies on changes unexpectedly.

1,863,043 | Tricky Golang interview questions - Part 2: BigO of len(...) | An example I want to discuss is quite simple and requires knowledge about how some data types are... | 0 | 2024-05-23T16:50:48 | https://dev.to/crusty0gphr/tricky-golang-interview-questions-part-2-bigo-of-len-2om9 | go, interview, tutorial, programming | An example I want to discuss is quite simple and requires knowledge about how some data types are constructed under the hood.
**Question: What is the time complexity of `len(...)` for each data type**
```go
package main
import (
"fmt"
)
func main() {
_ = len("string")
_ = len([]int{1, 2, 3})
_ = len(map[string]int{"one": 1, "two": 2, "three": 3})
}
```
The answer to this question is very easy:
**The time complexity of the `len(...)` for all cases is O(1).**
If you answer like this, the interviewer will come up with the following question: **why?** To answer this question, we need to look under the hood of each of the types.
### String
According to the Go documentation string type can be represented as a struct, a **StringHeader**. StringHeader is the runtime representation of a string.
```go
type StringHeader struct {
Data uintptr
Len int
}
```
- `Data` is a pointer, which points to an underlying (backing) byte array that stores the string data
- `Len` is the length of an underlying (backing) byte array
### Slice
Slice can also be represented as a struct, a **SliceHeader**. SliceHeader is the runtime representation of a slice.
```go
type SliceHeader struct {
Data uintptr
Len int
Cap int
}
```
- `Data` is a pointer, which points to an underlying (backing) byte array that stores the string data
- `Len` is the length of an underlying (backing) byte array
- `Cap` is the capacity of the slice.
### Map
Map is a bit more complex data structure and is represented as a [package](https://go.dev/src/runtime/map.go) in Go. In this package, we can find the map header struct with its corresponding fields.
```go
type hmap struct {
count int
flags uint8
B uint8
noverflow uint16
hash0 uint32
buckets unsafe.Pointer
oldbuckets unsafe.Pointer
nevacuate uintptr
extra *mapextra
}
```
We need the `count` field for this struct. According to the comments
- `count` is live cells == size of map or simply length of map
Now we know how these data structures are constructed under the hood we can answer the follow-up question by the interviewer:
**Why len(...) operations are O(1)?**
___
The `Len` function simply returns the value of the field in the header responsible for storing the length.
___

Many are running after the trend only to find themselves stuck in a vicious cycle where money and resources have been spent and now it's too late to get out. So it is to no surprise that so many leaders are raising their voices on the side effects of agile. Here I wanted to share some of my observations from both experience and reading online content on this topic. To start I truly empathise with the trauma endured by those in the tech world who have been forced into the maze of scrum or whatever other framework under the umbrella of agile. As an agile practitioner I cannot negate these horror stories, so before I continue with my 2 cents I wanted to make it clear that I totally understand why people are standing up to express their feelings of frustration and disillusionment.
**The question is this, has agile fallen ?** I would say yes and no.
Now let's look at the real life example of an average corporate that has adapted this fancy new way of working and is rapidly trying to convert their entire company into an agile superhero. They have big dreams which is commendable,
so what's the big deal ? Well everything. Diving deeper, many companies are using this term "agile" as a tool to cover up waterfallish way of doing business, for them agile is nothing more but just business. They are looking at it as means to cut down budget to layoff onshore and re hire offshore, then demand projects to be completed on time and with quality and when these high expectations are not met someone has to be blamed and in our case it's the mister agile. This type of stressful environment with constant changes and unstable teams not only creates burnout but most of all becomes the bottleneck for teams to deliver better product in shorter time. So the very thing which supposed to aid in continuous improvement has become the monster that's stopping them from growing.
**Let's ask ourselves is this really what agility is?**
On the other hand the issue is the focus on certification over mindset, project managers are undergoing scrum conversion but instead of carefully leading their teams through the transformation by upholding the 12 principles they are forcibly imposing this new way on them without allowing for the room to experiment, make mistakes, learn and grow together as a unit. Agile will not work but certainly fail when we use it to conceal our micromanaging ways. It cannot thrive in a rigid climate where the focal point is how many story points can you deliver in 2 weeks and how fast can you make this and that happen. Instead true agility facilitates a pipeline for both business and tech to have transparent conversations in a safe fearless environment with the customer at the center and the teams having the power to share their technical expertise. So any agile framework will expose the weaknesses that the system in place has and it is up to the leadership if they desire true shift or not.
Nevertheless we rarely see holistic agility happen in real life not because agile is bad (it's like saying all chocolate is bad when in fact good quality cacao is a superfood if consumed in wisdom), but because there is misalignment between the leadership and its employees. Real changes start at the top and trickle down, if you are seeing great dissatisfaction with agile at your work place ask yourself if your teams are encouraged to fail fast or are they being reprimanded for not meeting the highly favoured velocity. We have to stop using agile as a mantra but instead be open to trying new things, if one way doesn't work for your team, try something else. It is about building healthy teams in the end and amplifying creativity and growth. It is not all size fits all type of method but an invitation to a journey of discovery of what works for you and not against you. So my encouragement to the struggling scrum masters and teams would be to do what's best for everyone, have empathy and don't be afraid of uncomfortable conversations.

1,863,036 | Workday Security: Everything You Need to Know | If you're a malicious actor in cyberspace, you could do much worse than targeting a Workday instance... | 0 | 2024-05-23T16:41:38 | https://www.suridata.ai/blog/workday-security/ | cybersecurity, devops | If you're a malicious actor in cyberspace, you could do much worse than targeting a Workday instance at a large corporation. As one of the world's leading Human Capital Management (HCM) applications, Workday holds valuable data from employees and businesses worldwide.
The scale of [Workday's user base](https://techreport.com/statistics/workday-inc-statistics/) hints at the level of risk: 50 million users in over 170 countries. Over a million users access Workday every hour, executing 365 billion transactions annually. The platform's scale and inherent risks prompt a strict security approach.
Workday has rigorous security controls protecting its infrastructure. However, the problem is that much of the risk exposure inherent in Workday exists outside of what the company provides.
[Source](https://www.thomsondata.com/customer-base/companies-that-use-workday-hcm.php)
**What is Workday Security?**
-----------------------------
**Workday security is a series of security steps, protocols, and [information security controls](https://www.suridata.ai/blog/infosec-guide-to-information-security-controls/) to mitigate risks in the complex Workday environment. **Workday runs in highly secure data centers with network and infrastructure security operations. **The company enforces strict application security (AppSec) policies, and all data is encrypted and subject to segregation by the client to protect the multi-tenant architecture. **
Passwords are "native login," always hashed---never stored or transmitted in their actual forms. However, it's worth paying attention to the type of password hashing algorithm used, as older methods may be inefficient. Modern algorithms like bcrypt or Argon2 are adaptive and more resistant to attacks, making passwords significantly more difficult and time-consuming to track. A modern, customizable hashing method is crucial to protect your Workday passwords.
But Workday offers other crucial security features. The whole application is subject to a single security model, so all user interactions are subject to the same policies and enforcement mechanisms. The platform also offers single-sign-on (SSO) using security assertion markup language (SAML) and multi-factor authentication (MFA).
Consider what's going on inside a typical Workday instance. You might have salary and benefit information for thousands of employees worldwide. Employees can see their salary and benefits, not anyone else's. Administrative users may have greater visibility into this private information and be able to define access controls and security configurations.
This power ensures that no one sees what they're not supposed to see and that no outsider can view, exfiltrate, modify, or delete any data. Still, Workday is a SaaS app like any other, so it suffers from the same SaaS security challenges. Just like you would [secure your Salesforce environment](https://www.suridata.ai/blog/essential-steps-to-a-secure-salesforce-environment/) to protect customer data, you should apply extra security measures to your Workday platform to protect employees' private information.
[Source](https://view.ceros.com/workday/chapter-2-workday-security-mb-update)
**Why Should You Care About Securing Your Workday Platform?**
-------------------------------------------------------------
**Workday's extensive user base and dynamic functionality make it vulnerable to cyber threats.** At most Workday companies, virtually every employee can access the software, subject to a broad and often complex range of permissions. **The software integrates with other systems, too, which further expands the attack surface. **
Despite having its robust security features, Workday still faces various risks. **Most of these risks stem from using and integrating this SaaS app with other apps, but they can be mitigated with the proper [SaaS security best practices](https://www.suridata.ai/blog/saas-security-best-practices/).** As a Workday client, here are the common security threats you should be concerned about:
- **Phishing attacks**---Malicious actors can trick employees into sharing their Workday login credentials or other information that lets them gain unauthorized access to the application.
- **Credential stuffing attacks**---If attackers have stolen passwords, such as those on the dark web, they can try to access Workday by pairing known user emails with possible passwords. This attack can work if MFA is not switched on and users use the same password for personal accounts.
- **Insider threats**---Employees may abuse their access to the application for many reasons, ranging from curiosity to disgruntlement and greed. Privileged users comprise the most severe insider threat.
- **API threats/integrations**---Workday connects with many popular enterprise applications through its application programming interface (API). The same API can be the basis for integration with virtually any software. Depending on how you configure the API, it may be vulnerable to threats like broken access control or injection attacks. Left un-remediated, vulnerable APIs can leak data to unauthorized parties.
- **Supply chain attacks**---Workday offers an integrated development environment (IDE) so developers can build custom add-ons and integrations for the software. By allowing custom code from outsiders, Workday could enable insecure software development processes. This exposes Workday customers to supply chain attacks like malicious code injections, social engineering, and compromised dependencies.
[Source](https://www.hbs.net/blog/how-software-supply-chain-attacks-work/)
**Challenges in Maintaining Workday security **
-----------------------------------------------
### **1\. Overprivileged accounts**
It is possible to let some Workday accounts become overprivileged, even if accidentally. For example, if a user has an admin role but then switches to a new job that does not require admin access and that access is not revoked, the user has excessive privileges. **Bad actors can exploit these to access and steal sensitive data, manipulate settings, or approve financial transactions. **
### **2\. Complexity of roles, hierarchies, and organizational structures**
Workday allows you to create highly complex user roles with access rights that map to organizational structures and hierarchies. This level of detail is excellent because you can set up your access how you want it. However, **organizations are dynamic, and over time, the role definitions you set up will become obsolete, creating risk exposure in the process. **
### **3**. **Lack of visibility over access controls**
The complexity of roles and their respective privilege leads to a situation where security admins may lack visibility into access controls. Workday does provide an interface with a view of access controls, but **when there are thousands of users to manage, with varying and ever-changing permission levels, admins struggle to parse who can do what on the software.**
**6 Steps to Improve Workday Security**
---------------------------------------
### **1\. Monitor security configurations**
Security admins' flexibility and discretion can lead to insecure configurations, such as overly permissive bring-your-own-device (BYOD) policies or a lack of MFA. These misconfigurations allow attackers to enter your systems and can be very challenging to spot. **To monitor security configurations properly, you should use an automated monitoring tool like Suridata, which scans configurations continuously and flags problematic ones.**
[Source](https://www.digitalguardian.com/blog/ultimate-guide-byod-security-overcoming-challenges-creating-effective-policies-and-mitigating)
### 2\. **Create a privileges inventory and regularly update it**
Keep your Workday access model simple and map it clearly to your organizational model and role definitions. The result will be an inventory of privileges that identifies what every type of user can see and do on Workday. **This inventory should include the privileges granted to Workday integration system users (ISUs) and Integration Security Groups (ISSGs).** Keeping this inventory up to date has to be someone's job, and executive sponsorship may be necessary to ensure the budget to cover this cost.
### **3\. Deploy API security and third-party security countermeasures**
The Workday API is a potential attack surface, so deploying countermeasures that mitigate API risk is a best practice. Firstly, it's worth familiarizing yourself with the top 10 risks for [OWASP API security](https://www.openappsec.io/post/the-developer-s-guide-to-owasp-api-security). This list gives you a comprehensive overview of the threats to look out for and how attackers exploit these gaps. Then, **using a dedicated API security solution, you can scan your environment for "rogue" APIs that may have been abandoned but expose Workday data to external API clients.** These tools can also monitor API security settings and flag insecure APIs.
### **4**. **Employ Secure DevOps practices**
**If your organization uses the Workday IDE and leverages DevOps, you should employ AppSec methods in your development process.** One key component of AppSec is code scanning, for which you can employ SAST and [DAST tools](https://www.jit.io/a/appsec-tools/top-dast-tools-for-2024) to identify vulnerabilities early. Integrating "shift left" security remediation can also help you embed the proper security controls during development, preventing you from having to fix vulnerabilities while your Workday app is running.
[Source](https://xebia.com/blog/how-to-make-your-web-application-more-secure-by-using-static-application-security-testing-part-1-of-5-in-application-security-testing-series/)
### **5\. Continuous compliance monitoring**
**The personnel data on Workday is subject to several laws regarding consumer privacy, depending on where you operate.** If you have employees in California, you must [comply with CCPA](https://www.memcyco.com/home/ccpa-compliance-checklist/), for example. If you're in Europe, it's GDPR. Violations of these laws can be costly and time-consuming to remediate.
You can reduce your compliance risk by continuously monitoring for compliance (for instance, checking that data is in the correct sovereignty and no data about German citizens is stored in France).
### **6\. Continuously scan for insecure data **
Workday is likely just one element in your broader SaaS ecosystem. It's also likely to be connected to other SaaS apps you use, such as online storage solutions. One risk in these conditions is that users will move data from Workday to another app, such as an online storage platform. This data storage can be highly insecure, leading to the risk of breach, exfiltration, and all the expensive remediation actions that follow such an event.
**SaaS security solutions like Suridata can continuously scan for personnel data across the entire SaaS ecosystem, automatically flagging data that needs to be removed and providing detailed insights into the issue so you can activate the proper remediation workflow. **
**Making Workday SaaS Secure**
------------------------------
Workday has many security features, but the software remains vulnerable to threats like phishing attacks, API attacks, and brute force. Complex access rules compound the problem. To make Workday more secure, you must implement countermeasures addressing these risks.\
Suridata can make securing your Workday platform and data much more manageable. The Suridata tool scans your entire SaaS ecosystem (Workday and beyond, no matter how many SaaS apps you have), monitoring Workday's security configurations, spotting any abnormal user behavior, and accurately identifying data that might have been mistakenly or maliciously exported from Workday. **Interested in seeing it in action?

1,863,005 | Array Expansion in Flink SQL | I’ve recently started my journey with Apache Flink. As I learn certain concepts, I’d like to share... | 0 | 2024-05-23T16:34:41 | https://dev.to/sandonjacobs/array-expansion-in-flink-sql-40c9 | flink, flinksql, sql | I’ve recently started my journey with [Apache Flink](https://flink.apache.org/). As I learn certain concepts, I’d like to share them. One such "learning" is the expansion of array type columns in Flink SQL. Having used ksqlDB in a previous life, I was looking for functionality similar to the EXPLODE function to "flatten" a collection type column into a row per element of the collection. Because Flink SQL is ANSI compliant, it’s no surprise this is covered in the standard.
There are cases where fact data might contain an array column, perhaps with a collection of codes or identifiers that can later be used to join with dimension data. The end goal may be a read-optimized view of these facts to each dimension identified in that area.
## The Why
Let’s lay the foundation with a quick review of the terms “fact data” and “dimension data”. Fact data typically contains quantitative data of a business process. In an event streaming world, we can think of event streams as fact data - detailing actions of users or other upstream systems. For instance, an online shopper just completed a purchase. A fact event could contain the item identifiers and quantities of the purchased shopping cart, along with identifying information about the user, additional shipping information, and so forth.
Notice the use of the terms “identifiers” and “identifying” in the fact event data, thus making this event fairly “flat.” There are various reasons for this pattern - avoiding redundant/superfluous information, which makes the events themselves smaller. This design pattern would also provide flexibility to update the detailed information about those identified entities.
These details are known as dimension data, and when joined with fact data provide just that to our event streams - **_dimensionality_**. When our user dimension data is joined to these purchase event facts, we can then glean the details about the purchasing user. We now know their name, email address, shipping and billing information, and other contact information pertaining to doing business with them. As for the products purchased, this purchase event can now be joined to detailed product dimension data by the inventory system to earmark the purchased quantities. Meanwhile, the inventory system can update a typo in the description of this product because it’s not reliant on anything in the purchase event other than the identifier of the product(s).
## A Sample Use Case
Let’s use the NOAA Weather Service API data model to illustrate this array expansion functionality. The Flink tables described in this example are a result of using Kafka Connect to source data from the REST APIs, apply a set of Single Message Transformations, and write that data to Apache Kafka topics.
## Dimension Data
Weather "happens" in specific locations. The NOAA defines these locations as `zone` entities. A zone describes a geographic location, with multiple forecast offices, radar stations, and (in some cases) time zones. A Flink table holding this data might look something like this:
```
describe `ws_zones`;
```
| Column Name | Data Type | Nullable | Extras |
|:---------------:|:-------------------:|:--------:|:-------------------------:|
| zoneId | STRING | NOT NULL | PRIMARY KEY, BUCKET KEY |
| url | STRING | NULL | |
| name | STRING | NULL | |
| zoneType | STRING | NULL | |
| state | STRING | NULL | |
| cwas | ARRAY<STRING> | NULL | |
| forecastOffices | ARRAY<STRING> | NULL | |
| timeZones | ARRAY<STRING> | NULL | |
| radarStation | STRING | NULL | |
| ts | TIMESTAMP_LTZ(3) | NULL | METADATA FROM 'timestamp' |
## Fact Data
When a weather alert is created, updated, or expires, the API describes that alert entity with the list of affected zones. A Flink table for active alerts might have a schema such as:
```
describe `ws_active_alerts`;
```
| Column Name | Data Type | Nullable | Extras |
|:-----------------:|:-------------------------:|:--------:|:---------------------------------------------------------------------:|
| id | STRING | NOT NULL | PRIMARY KEY, BUCKET KEY |
| areaDesc | STRING | NULL | |
| geocodeSAME | ARRAY<STRING> | NULL | |
| geocodeUGC | ARRAY<STRING> | NULL | |
| affectedZones | ARRAY<STRING> | NULL | |
| sent | TIMESTAMP(3) | NULL | |
| effective | TIMESTAMP(3) | NULL | |
| onset | TIMESTAMP(3) | NULL | |
| expires | TIMESTAMP(3) | NULL | |
| ends | TIMESTAMP(3) | NULL | |
| status | STRING | NULL | |
| messageType | STRING | NULL | |
| category | STRING | NULL | |
| severity | STRING | NULL | |
| certainty | STRING | NULL | |
| urgency | STRING | NULL | |
| event | STRING | NULL | |
| sender | STRING | NULL | |
| senderName | STRING | NULL | |
| headline | STRING | NULL | |
| description | STRING | NULL | |
| instruction | STRING | NULL | |
| response | STRING | NULL | |
| NWSheadline | ARRAY<STRING> | NULL | |
| eventEndingTime | ARRAY<TIMESTAMP(3)> | NULL | |
| expiredReferences | ARRAY<STRING> | NULL | |
| eventTs | TIMESTAMP_LTZ(3) ROWTIME | NULL | METADATA FROM 'timestamp', WATERMARK AS eventTs - INTERVAL '5' MINUTE |
## Array Expansion
In the `ws_active_alerts` table, we see the column `geocodeUGC` of type `ARRAY<STRING>`. These codes correlate to the identifiers for the zone entities from the `ws_zones` dimension table.
| id | geocodeUGC | severity | category | status | onset | effective |
|:---------------------------------------------------------------------:|:--------------------------------:|:--------:|:--------:|:------:|:-----------------------:|:-----------------------:|
| urn:oid:2.49.0.1.840.0.e98d53f97bfcd60fcf971e613b85819ae1ec3cbb.005.1 | [TXC183, TXC423, TXC459, TXC499] | Severe | Met | Actual | 2024-05-15 15:45:00.000 | 2024-05-15 15:45:00.000 |

In Flink SQL, a cross join is a type of join that returns the [Cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) of the two tables being joined. The Cartesian product is a combination of every row from the first table with every row from the second table. This feature can be particularly useful when you need to expand an array column into multiple rows.
With that in mind, let’s expand the rows of ws_active_alerts using CROSS JOIN UNNEST. For each row in the ws_active_alerts table, UNNEST flattens the array column geocodeUDC of that row into a set of rows. Then CROSS JOIN joins this new set of rows with the single row from the ws_active_alerts table. So the result of UNNEST could be thought of as a temporary table - for the scope of this operation.
```
select
active.`id` as `alertId`,
`ActiveAlertsByUgcCode`.geocodeugc as `zoneId`,
active.`event` as `event`,
active.`status` as `alertStatus`,
active.`severity` as `severity`
from ws_active_alerts active
CROSS JOIN UNNEST(active.geocodeUGC) as `ActiveAlertsByUgcCode`(geocodeugc);
```
The results of this query yield a new row for each zone value of the alert.
| alertId | zoneId | event | alertStatus | severity |
|:---------------------------------------------------------------------:|:------:|:-------------:|:-----------:|:--------:|
| urn:oid:2.49.0.1.840.0.e98d53f97bfcd60fcf971e613b85819ae1ec3cbb.005.1 | TXC183 | Flood Warning | Actual | Severe |

## Join Facts with Dimensions
The goal here is to answer some location questions with the data on hand.
- What are the states affected by a given alert?
- How many alerts are active for a given state?
If we join our expanded facts about alerts with the dimension data from the zone definitions, we can find the affected states of each alert.
```
select
active.`id` as `alertId`,
`ActiveAlertsByUgcCode`.geocodeugc as `zoneId`,
zone.state as `state`
from ws_active_alerts active
CROSS JOIN UNNEST(active.geocodeUGC) as `ActiveAlertsByUgcCode`(geocodeugc)
LEFT JOIN ws_zones zone ON zone.zoneId = `ActiveAlertsByUgcCode`.geocodeugc;
```
| alertId | zoneId | state |
|:---------------------------------------------------------------------:|:------:|:-----:|
| urn:oid:2.49.0.1.840.0.e98d53f97bfcd60fcf971e613b85819ae1ec3cbb.005.1 | TXC183 | TX |
| urn:oid:2.49.0.1.840.0.e98d53f97bfcd60fcf971e613b85819ae1ec3cbb.005.1 | TXC423 | TX |
| urn:oid:2.49.0.1.840.0.e98d53f97bfcd60fcf971e613b85819ae1ec3cbb.005.1 | TXC459 | TX |
| urn:oid:2.49.0.1.840.0.e98d53f97bfcd60fcf971e613b85819ae1ec3cbb.005.1 | TXC499 | TX |
The results of this join operation could be a new table with the read-optimized data needed by a microservice to answer the question of “give me the active alerts for a given state.”
```
-- create new table
create table alert_zone_state (
`alertId` STRING,
`zoneId` STRING,
`state` STRING,
PRIMARY KEY (`alertId`, `zoneId`) NOT ENFORCED
) with (
'value.format' = 'avro-registry',
'kafka.cleanup-policy' = 'delete',
'kafka.retention.time' = '10 minutes'
);
-- load that table with the results of the join
insert into alert_zone_state select
active.`id` as `alertId`,
`ActiveAlertsByUgcCode`.geocodeugc as `zoneId`,
zone.state as `state`
from ws_active_alerts active
CROSS JOIN UNNEST(active.geocodeUGC) as `ActiveAlertsByUgcCode`(geocodeugc)
LEFT JOIN ws_zones zone ON zone.zoneId = `ActiveAlertsByUgcCode`.geocodeugc;
select * from alert_zone_state where state is not null;
```
Here's a screenshot from my Flink SQL Workspace in Confluent Cloud.
But let's expand on this with a new table to get a count of the distinct active alerts for all states:
```
-- create a new table
create table alert_counts_for_states (
`state` STRING,
`alertCount` INTEGER,
PRIMARY KEY (`state`) NOT ENFORCED
) with (
'value.format' = 'avro-registry',
'kafka.cleanup-policy' = 'compact'
);
-- load the counts into the new table from the previous table we created
insert into alert_counts_for_states
select
`state`,
cast(count(distinct(`alertId`)) as INTEGER) as `alertCount`
from alert_zone_state where `state` is not null
group by `state`;
-- query the table
select * from alert_counts_for_states;
```
The results of this query might look like this in my Flink SQL Workspace.
## Land the Plane
`CROSS JOIN UNNEST` proves to be a useful tool to unpack array types in source datasets. We can't always rely on the provider of source data to normalize these raw datasets to meet our application needs.
I hope you find this helpful in your journey with Flink SQL.

1,858,799 | Internal Developer Platform vs Internal Developer Portal | In today's highly competitive software development landscape, organizations are constantly seeking... | 0 | 2024-05-23T16:33:00 | https://www.devzero.io/blog/internal-developer-platform-vs-internal-developer-portal | tooling, terraform, automation, devops | In today's highly competitive software development landscape, organizations are constantly seeking ways to enhance their internal processes and empower their development teams. Two commonly used tools in this quest are internal developer platforms and internal developer portals. While both serve as valuable resources, understanding the differences between the two is crucial in determining which tool is best suited for your team's needs.
## What is an Internal Developer Platform?
An [internal developer platform](https://www.devzero.io/blog/what-is-an-internal-developer-platform), often referred to as a platform-as-a-service (PaaS) provides a centralized environment for developers to create, test, and deploy applications. It offers a set of pre-configured tools, frameworks, and infrastructure, allowing developers to focus solely on writing code and accelerating the development process.
By utilizing an internal developer platform, companies can streamline their software development lifecycle, reduce time-to-market, and improve overall efficiency. These platforms enable developers to leverage a wide range of services, such as containerization, automatic scaling, and continuous integration/continuous deployment (CI/CD), without having to worry about the underlying infrastructure.
For instance, renowned companies like Salesforce and Microsoft Azure offer robust internal developer platforms that empower their respective developer communities to build cutting-edge applications with ease. These platforms provide a seamless experience, enabling developers to quickly spin up new environments, collaborate with team members, and leverage built-in monitoring and debugging tools.
## Defining an Internal Developer Portal
An internal developer portal, on the other hand, serves as a repository of resources, documentation, and APIs (Application Programming Interfaces) that support and facilitate the development process. It offers developers a centralized location to access information, collaborate, and gather knowledge to enhance their productivity.
Internal developer portals play a crucial role in promoting knowledge sharing and fostering a culture of collaboration within development teams. They provide developers with access to comprehensive documentation, including coding standards, best practices, and architectural guidelines, ensuring consistency and quality across projects.
Companies such as Google and Amazon have successfully implemented internal developer portals, ensuring their development teams have all the necessary tools and information to deliver top-notch solutions. These portals offer features like API documentation, code samples, and interactive forums, enabling developers to learn from each other, ask questions, and share insights.
Moreover, internal developer portals often integrate with other tools and services, such as version control systems, issue tracking systems, and project management platforms. This integration further enhances the development workflow, allowing developers to seamlessly transition between different stages of the software development lifecycle.
Overall, internal developer portals serve as a valuable resource for developers, providing them with the necessary information and tools to build high-quality software solutions efficiently. They empower developers to stay up-to-date with the latest technologies, collaborate effectively, and deliver exceptional results.
## Key Differences Between Internal Developer Platforms and Internal Developer Portals
## Functionality and Features
One of the primary differences between an internal developer platform and an internal developer portal lies in their core functionality. While an internal developer platform focuses on providing a complete development environment, an internal developer portal primarily acts as a knowledge hub.
For example, a developer platform might include features like automated deployment, built-in quality testing, and continuous integration tools. On the other hand, a developer portal might offer documentation, API reference guides, and community forums to support developers throughout the development lifecycle.
## User Interface and Experience
When it comes to user interface and experience, internal developer platforms often prioritize simplicity and ease of use. They offer intuitive interfaces, streamline workflows, and automate repetitive tasks, enabling developers to quickly build and deploy applications.
In contrast, internal developer portals typically focus on creating a seamless browsing experience. They provide comprehensive search functionalities, categorize resources effectively, and ensure swift access to relevant information. This user-centric approach enhances productivity and knowledge sharing among developers.
## Integration and Compatibility
While both internal developer platforms and internal developer portals aim to integrate seamlessly with existing systems and tools, their approaches differ.
Internal developer platforms typically provide ready-to-use integrations with popular development tools, version control systems, and third-party services. This compatibility ensures a smooth development workflow and eliminates any potential roadblocks.
Internal developer portals, on the other hand, offer extensive API documentation and guidelines to enable developers to integrate their applications with various services. They provide the necessary resources to ensure compatibility, while also enabling developers to leverage the power of external APIs.
## Pros and Cons of Internal Developer Platforms
## Advantages of Internal Developer Platforms
Internal developer platforms present numerous advantages for development teams.
- Increased Productivity: By providing a pre-configured environment and automating processes, internal developer platforms streamline development workflows and significantly boost productivity. For example, XYZ Corporation reported a 30% increase in developer productivity after implementing their internal developer platform.
- Faster Release Cycles: The standardized infrastructure and built-in deployment automation enable organizations to release new features and updates rapidly. ABC Corporation witnessed a 50% reduction in release cycles after adopting an internal developer platform.
## Potential Drawbacks of Internal Developer Platforms
Despite their advantages, internal developer platforms may also have some limitations.
- Learning Curve: Mastering the platform's tools and frameworks might require a learning curve for developers. Companies should allocate adequate resources for onboarding and training.
- Dependency on Platform Provider: Organizations relying heavily on external internal developer platform providers might face challenges if the provider discontinues their services or undergoes substantial changes.
## Pros and Cons of Internal Developer Portals
## Benefits of Internal Developer Portals
Internal developer portals offer distinct benefits to development teams.
- Knowledge Sharing and Collaboration: By providing a centralized hub of information, developer portals foster collaboration, knowledge sharing, and quick access to resources. This accelerates development cycles and reduces time spent searching for information.
- Onboarding New Developers: Developer portals serve as invaluable resources for onboarding new team members, providing them with the necessary documentation and guidelines to get up to speed quickly.
## Possible Limitations of Internal Developer Portals
Internal developer portals may also have some potential limitations.
- Information Overload: Without proper organization and prioritization, developer portals can become overwhelming, making it challenging for developers to find the specific resources they need.
- Outdated or Incomplete Documentation: In dynamic development environments, keeping documentation up to date can be a challenge. Outdated or incomplete documentation can lead to confusion and hinder development processes.
## Choosing the Right Tool for Your Team
## Assessing Your Team's Needs
Before making a decision between an internal developer platform and an internal developer portal, it is crucial to assess your team's unique needs and goals. Consider factors such as project complexity, team size, and preferred development workflows.
For example, if your team is primarily focused on rapid development cycles and requires a standardized environment, an internal developer platform might be the ideal choice. Conversely, if your team values collaboration, knowledge-sharing, and quick access to resources, an internal developer portal could provide the necessary tools and infrastructure.
## Evaluating Your Current Infrastructure
When selecting between an internal developer platform and an internal developer portal, it is essential to evaluate your existing infrastructure. Consider compatibility with your current development tools, architecture, and overall IT ecosystem.
For instance, if your organization heavily relies on specific development tools or incorporates legacy systems, an internal developer platform with flexible integration capabilities might be the way to go. However, if your current infrastructure is diverse and open to external APIs, an internal developer portal can seamlessly integrate and enhance your existing ecosystem.
## Considering Future Growth and Scalability
Lastly, it is essential to consider the scalability and future growth potential of your chosen tool. As your team expands and your projects become more complex, you need a tool that can support your evolving needs.
For example, if you anticipate substantial growth and an increasing number of development projects, an internal developer platform might provide the scalability and automation required. Conversely, if your team is smaller and the focus is on knowledge sharing and collaboration, an internal developer portal can effectively cater to your needs.
Ultimately, the choice between an internal developer platform and an internal developer portal depends on the specific requirements and objectives of your development team. By carefully assessing your team's needs, evaluating your current infrastructure, and considering future growth, you can make an informed decision that maximizes productivity, efficiency, and collaboration within your organization. | shohams |

I worked on several technologies like... | 0 | 2024-05-23T16:30:47 | https://dev.to/aws-builders/-streamlining-kubernetes-deployment-setting-up-eksctl-kubectl-and-aws-cli-on-amazon-linux-2--1j16 | aws, kubernetes, devops, beginners | Hey! It's Sarvar Nadaf again, a senior developer at Luxoft. I worked on several technologies like Cloud Ops (Azure and AWS), Data Ops, Serverless Analytics, and Dev Ops for various clients across the globe.
Today, we'll look into AWS EKS's fundamentals. This post will assist you in setting up the various command-line interfaces that will enable you to communicate with the AWS EKS cluster from a laptop or other Linux-based device.
Today, we will configure ESKCTL, Kubectl, and the AWS CLI. With each Linux distribution, there are a few minimal requirements and differences. I'm setting up all of these command-line tools on an Amazon Linux 2 machine today. Simply, I'll obtain a free tier Amazon Linux 2 server and let's begin configuring command-line interfaces.
## **AWS CLI -**
The open-source AWS CLI is a really powerful resource. This enables our interaction with the entire AWS service. Just by doing a few simple steps, we may operate our AWS account from anywhere.
## **Prerequisite -**
- AWS Account
- IAM User
- Access key ID and Secret access key
1.Use the following command to become the root user. so no extra sudo command for each step.
```
[ec2-user ~]$ sudo su -
```
2.Become a Root User Use the following command to carry out a fast software update to make sure your instance's software packages are up-to-date:
```
[root ~]$ sudo yum update –y
```
3.Updating the server. Currently, we are downloading the zip file containing the AWS CLI package. To download the AWS CLI package from the URL, we are using the curl command. As you can see below, we are converting the package into awscli.zip using the -o option.
```
[root ~]$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv.zip"
```
4.Downloading AWS CLI Package Once the command has been executed successfully, we can use the ls command to view the awscli.zip file. We are now unzipping the zip file that is on our server.
```
[root ~]$ unzip -q awscli.zip
```
5.Checking package using ls command As soon as the zip file is unzipped, the entire awscli package is installed. To run and execute the awscli package, we are using the following command.
```
[root ~]$ ./aws/install
```
6.Installing AWS CLI After the AWS CLI has been successfully installed, we are just running the command below to see if it is functioning as expected or not. You have successfully configured the AWS CLI on your server if you can see the output similar to the one below.
```
[root ~]$ aws --version
```
7.Checking the AWS Version At this time, your IAM user information is being configured in the AWS CLI. To obtain programmatic access to all AWS services, we must submit the access key and secret access key of the IAM user. With the AWS Configure command, we must supply all the necessary information, including the region and region code for the connection you want to make. The output format must always be JSON, so we will receive the output in JSON format. We will be able to access the service that the IAM user has granted us access to.
```
[root ~]$ aws configure
```
8.Setting up AWS IAM User If you can see the result of the following command after setting up the AWS CLI, your server has been successfully set up for use with the AWS CLI.
```
[root ~]$ aws s3 ls
```
## **Kubectl -**
The Kubernetes API server can be reached using the command line program kubectl. When we access our AWS EKS cluster from our system, Kubectl is a big help. We can use our machine to access all of Kubernete's resources. Many operating system package managers contain the kubectl binary. It's frequently simpler to use a package manager for installation than to download and manually install everything.
1.Here, we're setting up a Kubernetes repository. One file must be created in order to build a repository. The file's repo extension contains information about the gpgkey and the kubenetes baseurl of kubectl. This file is located in the directory /etc/yum.repos.d.
```
[root ~]$ cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-\$basearch
enabled=1
gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOF
```
2.Updating Repo Using the cat command, we are checking that everything appears to be as expected.
```
[root ~]$ cat /etc/yum.repos.d/kubernetes.repo
```
3.Checking Repo Using the command below, we are installing the kubectl CLI right now.
```
[root ~]$ sudo yum install -y kubectl
```
4.Installing Kubectl After the kubectl CLI has been installed successfully, we use the version command to determine whether kubectl has been installed correctly or not.
```
[root ~]$ kubectl version
```
## **EKSCTL -**
The AWS EKS cluster can be interacted with using the tool EKSCTL. We'll carry out the operations necessary to create, update, manage, and delete the AWS EKS cluster. This command line interface for communicating with the AWS EKS Cluster is highly useful.
1.Here, we're using the curl command to download the most recent version of the eksctl package into a tar file, which we then untar under the tmp directory with the following command.
```
[root ~]$ curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
```
2.Installing and untar the eksctl Data from the untar eksctl package is being transferred to the /usr/local/bin directory.
```
[root ~]$ sudo mv /tmp/eksctl /usr/local/bin
```
3.Moving from tmp directory to bin directory After the eksctl CLI has been installed successfully, we use the version command to determine whether kubectl has been installed correctly or not.
```
[root ~]$ eksctl version
```
Congratulations! Kubectl, eksctl, and the AWS CLI you all have been installed successfully. We have witnessed the step-by-step installation process for all three CLIs. This CLI will undoubtedly be useful while using the AWS EKS cluster or learning about the AWS EKS. This personally helped me a lot since once you learn how to use the CLI, you won't need a console user interface to see things; just a few commands will give you access to all the information in your Linux terminal. If you have any questions, please post a comment below.

1,863,028 | Truncating Tables with Foreign Keys in Laravel | When working with databases in Laravel, there are times when you might need to clear data from tables... | 0 | 2024-05-23T16:21:30 | https://dev.to/rafaelogic/truncating-tables-with-foreign-keys-in-laravel-lac | laravel, webdev, programming, tutorial | When working with databases in Laravel, there are times when you might need to clear data from tables while ensuring the integrity of related data. A common task is truncating tables, but it becomes complex when foreign key constraints are involved. Here, I'll walk you through a custom Laravel Artisan command that simplifies truncating tables and removing related foreign keys.
The Command: **`php artisan table:truncate {table}`**
Assuming you already know how to create a command so let's dive directly into the code:
```php
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Schema;
class TruncateTableWithForeignKeys extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'table:truncate {table}';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Truncate a table and delete all related foreign keys';
/**
* Execute the console command.
*
* @return int
*/
public function handle()
{
$table = $this->argument('table');
// Drop foreign keys from other tables referencing this table's uuid column
$this->dropForeignKeysFromReferencingTables($table, 'uuid');
// Drop foreign keys from the specified table
$this->dropForeignKeysFromTable($table);
// Truncate the table
DB::table($table)->truncate();
$this->info("Table {$table} truncated and foreign keys dropped.");
return 0;
}
/**
* Drop foreign keys from the specified table.
*
* @param string $table
* @return void
*/
protected function dropForeignKeysFromTable($table)
{
$foreignKeys = $this->getForeignKeys($table);
Schema::table($table, function ($table) use ($foreignKeys) {
foreach ($foreignKeys as $foreignKey) {
$table->dropForeign($foreignKey);
}
});
}
/**
* Drop foreign keys from tables that reference the specified table's column.
*
* @param string $table
* @param string $column
* @return void
*/
protected function dropForeignKeysFromReferencingTables($table, $column)
{
$schemaManager = DB::getDoctrineSchemaManager();
$databasePlatform = $schemaManager->getDatabasePlatform();
$databasePlatform->registerDoctrineTypeMapping('enum', 'string');
$foreignKeys = [];
foreach ($schemaManager->listTableNames() as $tableName) {
if ($tableName !== $table) {
$foreignKeys[$tableName] = [];
foreach ($schemaManager->listTableForeignKeys($tableName) as $foreignKey) {
if ($foreignKey->getForeignTableName() === $table) {
$foreignKeys[$tableName][] = $foreignKey->getName();
}
}
}
}
foreach ($foreignKeys as $tableName => $keys) {
Schema::table($tableName, function ($table) use ($keys) {
foreach ($keys as $key) {
$table->dropForeign($key);
}
});
}
}
/**
* Get the foreign keys for the specified table.
*
* @param string $table
* @return array
*/
protected function getForeignKeys($table)
{
$schemaManager = DB::getDoctrineSchemaManager();
$keys = $schemaManager->listTableForeignKeys($table);
$foreignKeys = [];
foreach ($keys as $key) {
$foreignKeys[] = $key->getName();
}
return $foreignKeys;
}
}
```
### Scenarios for Using This Command
1. **Development and Testing**
In development or testing environments, you often need to reset the database to a known state. This command ensures that you can truncate tables without worrying about foreign key constraints.
```sh
php artisan table:truncate users
```
2. **Data Migration**
During data migration, you might need to clear tables before importing fresh data. This command ensures that tables are emptied correctly even when foreign key constraints exist.
```sh
php artisan table:truncate orders
```
3. **Cleaning Up Stale Data**
In some applications, certain tables might accumulate a lot of data that needs periodic cleanup. Using this command helps maintain database integrity while performing such operations.
```sh
php artisan table:truncate logs
```
Creating custom Artisan commands in Laravel allows you to encapsulate complex operations into simple, reusable commands. The TruncateTableWithForeignKeys command showcases how you can manage table truncation and foreign key constraints efficiently. This command can be particularly useful in development, testing, and data migration scenarios, ensuring your database operations remain smooth and error-free.
Feel free to customize the command further based on your specific needs and scenarios.

But this isn't the couch-potato kind; it's the kind that fuels innovation — finding ways to get more done with less effort. Why spend hours on repetitive tasks when a few lines of code can do the job for you?
This mindset has been my guiding star as I navigate my dual roles. On my spare time, I code; at nine-to-five (seven-thirty-to-five-thirty, actually), I manage my dad's paint store. Among my various responsibilities, one of the most daunting is calculating the cost and selling prices of our products. Now, if you're familiar with Brazil's tax system, you'll understand the gravity of this task. For those who aren't, let me paint you a picture.
In Brazil, taxes are a labyrinthine mess. Beyond federal tax rates, each state has the liberty to set its own tax rates, creating a patchwork of regulations that would make any sane person’s head spin. Enter 'substituição tributária' (ST) — a regime where the tax burden is transferred from the seller to the manufacturer or importer. The idea is to streamline tax collection, but in practice, it often complicates matters further, especially when products cross state lines.
Calculating these costs manually is not just tedious; it's a soul-crushing endeavor. The repetitive nature of punching numbers into a calculator, cross-referencing tax tables, and double-checking figures is enough to make anyone yearn for a better way. That's where my programmer's "laziness" kicked in. I saw a clear need for automation — a way to take these convoluted calculations and simplify them into a process that’s as effortless as possible.
Thus, the web-based price calculator project was born. Armed with formulas from my accountant and a determination to streamline our pricing workflow, I set out to build a tool that could handle the heavy lifting. This post will take you through the journey of its creation, detailing the code, the challenges, and the solutions. Along the way, I’ll share insights into how you too can leverage programming to simplify complex tasks in your work or business. So, let's dive in and explore how we can turn lazy into efficient.
## The Accountant's Formulas: Transforming Tedious Calculations into Computable Algorithms
In the world of business, especially one as intricate as a paint store, pricing products accurately is crucial. My accountant, the wizard behind our financial curtain, provided me with a set of formulas to calculate our costs and selling prices. These formulas consider various taxes and additional charges that are part and parcel of Brazil's complex tax landscape.
The general formula for calculating the cost is as follows:
`Cost Price = Unit Price + ICMS(%) + IPI(%) + Freight(%)
Selling Price = Cost Price + Markup(%) + Additional(%) + Federal Tax (fixed at 7%)`
It’s important to note that each percentage is applied on top of the previous values, compounding the total cost incrementally.
But it's not as straightforward as plugging numbers into a formula. The calculation of ICMS (a state tax) depends on whether the product falls under 'substituição tributária' (ST) or not, and this is where things get interesting.
For products without ST (identified by CFOP codes 5101, 5102, 6101, and 6102):
- If the ICMS rate is 4%, the effective ICMS in the formula becomes 13.27%.
- If the ICMS rate is 12%, the effective ICMS in the formula becomes 7.32%.
For products with ST (identified by CFOP codes 5401, 5403, 5405, 6401, 6403, and 6405):
- If the IPI rate is 0%, the ICMS in the formula is 19.7%.
- If the IPI rate is 1.3%, the ICMS in the formula is 20.3%.
- If the IPI rate is 3.25%, the ICMS in the formula is 21.26%.
- If the IPI rate is 6.5%, the ICMS in the formula is 24%.
I don’t entirely understand the logic behind these values — they’re the magic numbers handed down by my accountant. But I trust her expertise, and these are the values we need to work with.
### Manual Calculations: A Tedious Routine
Before automation, the process was as follows:
1. **Gather Information:** Collect the unit price, ICMS rate, IPI rate, freight percentage (if any), markup percentage, and additional charges.
2. **Apply Formulas:** Using the provided formulas, manually calculate the effective ICMS rate based on the CFOP code and applicable ICMS/ IPI rates.
3. **Calculate Cost Price:** Add up all the percentages and apply them to the unit price.
4. **Calculate Selling Price:** Add the calculated cost price to the markup, additional charges, and federal tax.
5. **Repeat: **Perform these steps for each product, using a calculator to ensure accuracy.
This manual process was not only time-consuming but also prone to errors. Every miscalculation could lead to incorrect pricing, impacting our profit margins or making us uncompetitive.
### From Manual to Algorithmic
The beauty of these steps is that they form an algorithm, a series of computable steps. And this is where automation shines. By translating these steps into code, I could create a tool that performs these calculations instantly and accurately. No more tedious number crunching, no more manual errors — just a streamlined, efficient process that ensures we get our pricing right every time.
In the next section, I'll walk you through how I transformed these formulas into a web-based price calculator, turning hours of work into a task that takes mere seconds.
## Implementing the First Part: From Supplier Invoices to a Functional MVP
In our paint store, every supplier sends us invoices in the form of XML files. These XML files are standardized by the Federal Revenue Service of Brazil, ensuring they follow a consistent structure. This consistency makes it feasible to automate the extraction of necessary data for our price calculations.
### Technologies Used
To build this solution, we chose a stack that includes:
- **Flask:** A lightweight web framework for Python that makes it easy to set up routes and handle requests.
- **Jinja2:** The templating engine used by Flask to render HTML pages dynamically.
- **JavaScript (with jQuery):** To handle client-side interactions and make AJAX requests for dynamic updates.
### Setting Up Routes
For the initial implementation, we set up two main routes: `index `and `calculate`.
#### `index `Route
The index route serves the main page of our application. It renders the form that allows users to upload an XML file, input the markup percentage, additional charges, and freight costs. We also set default values for these inputs to streamline the user experience.
```python
@app.route('/')
def index():
return render_template('index.html', product_data=[], markup=50, additional=5, freight=0, include_tax=False)
```
#### `calculate `Route
The `calculate `route processes the uploaded XML file. It extracts the necessary data, applies the formulas provided by my accountant, and calculates the cost and selling prices. This route then renders the results back to the `index.html` template.
```python
@app.route('/calculate', methods=['POST'])
def calculate():
if 'xmlFile' not in request.files:
return redirect(url_for('index'))
file = request.files['xmlFile']
if file.filename == '':
return redirect(url_for('index'))
markup = float(request.form['markup'])
additional = float(request.form['additional'])
freight = float(request.form['freight'])
include_tax = 'federalTax' in request.form
namespaces = {'nfe': 'http://www.portalfiscal.inf.br/nfe'}
product_data = extract_data_from_xml(file, namespaces)
for product in product_data:
cost_price = calculate_cost_price(product['Valor Unitário'], product['Alíq. ICMS'], product['Alíq. IPI'], product['CFOP'], freight)
selling_price = calculate_selling_price(cost_price, markup, additional, include_tax)
product['Preço de Custo Final'] = cost_price
product['Preço de Venda'] = selling_price
return render_template('index.html', product_data=product_data, markup=markup, additional=additional, freight=freight, include_tax=include_tax)
```
### Crafting the MVP
The Minimum Viable Product (MVP) focused on getting the basic functionality right. This included:
1. **Form Setup:** An HTML form for uploading XML files and inputting calculation parameters (markup, additional charges, freight, and federal tax inclusion).
2. **Data Extraction:** Using Python's `xml.etree.ElementTree` to parse the XML files and extract relevant product data.
3. **Calculation Logic:** Implementing the cost and selling price formulas in Python.
4. **Result Display:** Dynamically rendering the calculated prices back to the user through the HTML template.
Here’s the `index.html` template for the form and result display:
```html

```
With this MVP in place, we had a functional tool that could handle the complexities of our pricing calculations, saving us time and reducing the potential for errors. But this was just the beginning.
##Adding Interactivity: Editable Markup Fields for Dynamic Price Updates
In the real world, the need for flexibility in pricing is paramount. Sometimes, different products on the same invoice require different markup percentages. Manually re-uploading the XML file and recalculating prices each time a markup needs to be adjusted is not only inefficient but also prone to errors. To address this, I introduced an interactive, editable markup field that updates the selling price automatically. This is where JavaScript comes into play.
### Enhancing User Experience with JavaScript
To achieve this dynamic behavior, we needed to:
1. Make the markup field editable directly within the product table.
2. Use JavaScript to detect changes in the markup field and trigger recalculations.
3. Send the updated data to the server via AJAX and update the selling price without refreshing the page.
Here's a detailed breakdown of the implementation:
#### 1. Updating the HTML Template
First, we needed to ensure the markup field in our HTML table was editable and had the necessary attributes for our JavaScript to identify and manipulate it.
```html
<td><input type="number" class="markup-input" step="0.1" value="{{ markup }}" data-index="{{ loop.index0 }}"></td>
```
This line creates an input field within the table cell, sets its initial value to the current markup, and adds a `data-index`attribute to keep track of the product's position in the list.
#### 2. JavaScript for Real-Time Updates
We then added a JavaScript file to handle the dynamic updates. This script listens for changes in the markup input fields and makes AJAX requests to update the prices accordingly.
Here’s the content of `static/script.js`:
```javascript
$(document).ready(function() {
const productData = JSON.parse(document.getElementById('productData').textContent);
const additional = JSON.parse(document.getElementById('additionalData').textContent);
const freight = JSON.parse(document.getElementById('freightData').textContent);
const includeTax = JSON.parse(document.getElementById('includeTaxData').textContent);
$('.markup-input').on('input', function() {
let markup = $(this).val();
let index = $(this).data('index');
updatePrices(markup, index);
});
function updatePrices(markup, index) {
$.ajax({
url: '/update_prices',
method: 'POST',
contentType: 'application/json',
data: JSON.stringify({
markup: markup,
index: index,
product_data: productData,
additional: additional,
freight: freight,
include_tax: includeTax
}),
success: function(data) {
$('table').find('tr').eq(index + 1).find('td').eq(9).text('R$ ' + data.new_selling_price.toFixed(2));
}
});
}
});
```
This script does the following:
- Reads the product data and other relevant values from the hidden JSON elements in the HTML.
- Listens for input events on the markup fields.
- Sends an AJAX request to the server whenever a markup value changes, passing the updated markup and necessary data.
- Updates the displayed selling price with the new value returned from the server.
#### 3. Handling AJAX Requests in Flask
We needed a new route in our Flask app to handle the AJAX requests and perform the necessary recalculations.
Here’s the updated `main.py`:
```python
@app.route('/update_prices', methods=['POST'])
def update_prices():
data = request.get_json()
index = data['index']
markup = float(data['markup'])
additional = data['additional']
freight = data['freight']
include_tax = data['include_tax']
product_data = data['product_data']
product = product_data[index]
cost_price = calculate_cost_price(product['Valor Unitário'], product['Alíq. ICMS'], product['Alíq. IPI'], product['CFOP'], freight)
new_selling_price = calculate_selling_price(cost_price, markup, additional, include_tax)
return jsonify({'new_selling_price': new_selling_price})
```
This route:
- Receives the updated markup and product data via a JSON payload.
- Recalculates the cost and selling prices using the same formulas as before.
- Returns the new selling price to the client, which JavaScript then updates in the table.
#### 4. Adjusting the HTML Template
Finally, ensure that the HTML template includes the necessary scripts and hidden JSON data.
Here’s the updated `index.html`:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Calculadora de Preço de Venda</title>
<link rel="stylesheet" href="/static/style.css">

With these enhancements, we transformed a static form into an interactive tool that allows for real-time price adjustments. This not only streamlines our workflow but also provides flexibility in pricing, making the tool much more powerful and user-friendly. In the next section, I'll discuss potential future iterations and improvements to further enhance the functionality and usability of this project.
## Future Iterations: Enhancing Functionality and User Experience
With the basic functionality in place, there are several enhancements that can make the price calculator even more robust and user-friendly. Here are the next steps I'm considering for future iterations:
### 1. Configurations Page
Currently, the tax rates and CFOP codes are hard-coded into the application. This approach works for an MVP, but it's not scalable. Tax rates can change, and new CFOP codes with different tax regimes can emerge. To address this, I plan to implement a configurations page where users can update these values directly within the app.
- **Editable Tax Rates and CFOP Codes:** Allow users to add, edit, and delete tax rates and CFOP codes.
- **Persistent Settings:** Store these configurations in a database to ensure they are retained between sessions.
### 2. Drag-and-Drop XML Upload
To improve the user experience, I want to add drag-and-drop functionality for XML uploads. This would make the process more intuitive and quicker.
- **Drag-and-Drop Interface:** Implement a drag-and-drop zone for users to easily upload XML files.
- **Fallback to Button Upload:** Maintain the current file upload button as a fallback option.
### 3. Hosting on Store’s Domain
Currently, the application is running on a Heroku server. To give it a more professional look and ensure better accessibility, I plan to host it on the store's domain.
- **Custom Domain:** Migrate the app to be hosted on the store's domain.
- **Enhanced Accessibility:** Ensure the app is easily accessible to all users, including employees and customers.
### 4. Improved Aesthetics with CSS
While functionality is king, aesthetics shouldn't be neglected. A well-designed interface can significantly enhance the user experience. I plan to use CSS to make the page more visually appealing.
- **Modern UI Design:** Implement a clean, modern design for the app using CSS.
- **Responsive Design:** Ensure the app works well on different devices, including desktops, tablets, and smartphones.
## Conclusion
The journey of creating this web-based price calculator has been both challenging and rewarding. From automating tedious manual calculations to adding dynamic, real-time updates, each step has made the app more efficient and user-friendly. But the journey doesn't end here. With future iterations focusing on configurability, user experience, and professional hosting, the app will continue to evolve and serve its purpose even better.
Stay tuned for more updates as I continue to enhance and refine this project. If you're on a similar journey or have any suggestions, I'd love to hear from you! Let's keep innovating and making our lives (and jobs) a bit easier, one line of code at a time. | jampamatos |

1,863,012 | Defensive Functions and Input Validation in Python: Ensuring Error-Free Code | Writing defensive functions and validating input are essential for creating efficient and error-free... | 0 | 2024-05-23T16:08:41 | https://dev.to/myexamcloud/defensive-functions-and-input-validation-in-python-ensuring-error-free-code-nmp | python, programming, software, coding | Writing defensive functions and validating input are essential for creating efficient and error-free code. While type-hinting can provide helpful documentation, it is not enough to ensure the correct execution of a function. Developers must manually check and enforce the pre-conditions for a function to work properly and handle edge cases where invalid inputs are passed.
One example of this is calculating interest using the principal, rate, and years as input parameters. While the operation may seem simple, it is important to ensure that the input values are within a valid range for the function to execute correctly. This means that certain conditions must be met for the function to function properly.
To ensure this, we can do the following steps:
1. Use type hints to specify the expected data types for each input parameter.
2. Check the input types using conditional statements and raise type errors if the conditions are not satisfied.
3. Check for valid values of each input parameter and raise value errors if any of them are invalid.
4. Perform the calculation only if all the pre-conditions are met.
Let's take a look at how this would be implemented in Python:
`from typing import Union
`
`def calculate_interest(
principal: Union[int, float],
rate: float,
years: int
) -> Union[int, float]:
` `if not isinstance(principal, (int, float)):
raise TypeError("Principal must be an integer or float")
if not isinstance(rate, float):
raise TypeError("Rate must be a float")
if not isinstance(years, int):
raise TypeError("Years must be an integer")
if principal <= 0:
raise ValueError("Principal must be positive")
if rate <= 0:
raise ValueError("Rate must be positive")
if years <= 0:
raise ValueError("Years must be positive")`

Here, we are using conditional statements to validate the input and raising appropriate errors if any of the conditions are not met. This not only ensures the correct execution of the function but also improves its robustness by handling unexpected inputs.
It is worth noting that while Python also has assertion statements that can be used for input validation, they are not recommended for this purpose as they can easily be disabled and lead to unexpected behavior in production. Using explicit conditional statements is a best practice for enforcing pre-conditions, post-conditions, and code invariants.
In conclusion, writing defensive functions and validating input is crucial for creating reliable and efficient code. By following best practices and using proper input validation techniques, we can ensure that our functions work as intended and handle any potential errors seamlessly.

1,852,782 | Pursuing a Master's in Computer Science Without a CS Background: My Journey to the University of York | I've just been accepted into the University of York's online MSc course in Computer Science. During... | 0 | 2024-05-23T16:01:05 | https://dev.to/ken-amenomori/pursuing-a-masters-in-computer-science-without-a-cs-background-my-journey-to-the-university-of-york-5a45 | computerscience | I've just been accepted into the University of York's online MSc course in Computer Science. During my application process, I found many articles and blogs about postgraduate options helpful. However, there was scant information about the University of York, which made my decision-making process challenging. As I considered several schools, I want to share my experiences and the reasons behind my choice of York. I hope this article will assist you in making an informed decision, just as the other blogs helped me.
## My Background
I've been working as a software engineer while completing my undergraduate degree in law. Despite successfully managing in my role without a formal computer science background, I decided to pursue a master's degree to solidify my knowledge base and align with my peers professionally.
## Criteria
Given my background, I had a specific set of criteria for selecting a university. It’s no secret that not many schools are open to candidates without a traditional computer science background. If you’re looking to break into the field like I am, you might relate to the challenges I faced. Here’s what I looked for in a program:
* **No requirement for a CS bachelor’s degree**
* Availability of an online course (or a campus located in Japan)
* Reasonable tuition fees
* Ability to start studying as soon as possible
* Offers research opportunities (no specific topic in mind, but I was eager to explore this aspect of academia)
These criteria guided my search and ultimately influenced my decision on where to apply.
## School I chose
I chose [the University of York][1] for my online MSc course. While it may not be as widely recognized internationally as some other institutions in computer science, the University of York offers an excellent program for students without a traditional CS background. They provide online courses at a reasonable tuition fee of £9,000. The university requires a grade higher than 2:2, which is equivalent to a GPA between 2.8 and 4.0. Although my GPA was on the lower side, it still met their requirements. As a non-native English speaker, I had to submit my TOEFL score.
A significant advantage of York's program is the minimal documentation required for admissionーjust my alma mater's transcript and certification to prove my English proficiency. This streamlined the application process, eliminating the need for personal statements or letters of recommendation from my employer. Moreover, the start date was ideal; I applied in May, and the class begins on June 24th, allowing me to quickly focus on my studies.
Although it may not carry the same immediate name recognition in specific circles as other schools, the University of York is a member of the Russell Group, which comprises 24 leading UK universities. Given my specific needs and circumstances, it was the most suitable choice.
## Other options I considered
* [Georgia Tech][2]
Georgia Tech also offers online courses known as OMSCS. While a CS-related degree is preferable, it's not mandatory. Applicants need a 3.0 or higher GPA and a TOEFL score above 100 (IELTS is also acceptable). Three references are required, one from someone with an academic background. The course costs only $7,000. Georgia Tech is highly prestigious in the US. Although a CS degree is typically required, I've seen some students admitted without one, so it is worth a shot even if you don't have one.
However, I chose not to pursue this due to the lengthy preparation time, which didn't align with my goal to start studying as soon as possible.
* [University of Pennsylvania][3]
Penn offers the online Master of Computer and Information Technology(MCIT) degree. This program doesn't require a CS degree at all. Applicants should have a GPA of 3.0 or higher and a TOEFL score of 100 or more (IELTS is not accepted). It requires at least two letters of recommendation, multiple personal statements, and a resume. Penn is a member of the Ivy League, which is impressive until you see the tuition feesーthey're also Ivy League, but my bank account isn't. It costs more than $26,000. Plus, they don't exactly offer a computer science degree; it's more of a computer and information technology degree.
* [Japan Advanced Institute of Science and Technology][4]
Technically, they don't offer an online course, but they have attractive part-time graduate programs. Although it was one of the best options, the courses are primarily conducted in Japanese, and I was keen on improving my English. FYI, if you choose this school, you really need to devote yourself to research.
* University of the People
This is actually an undergraduate institution, offering tuition-free education, which could have been an appealing option. However, since it's an undergraduate program, it would require committing four years or more, a longer duration than I was willing to invest.
* University of London
Similar to the University of the People, the University of London would have required spending three years, which was not feasible for my plans.
## Finally...
I have chosen the University of York for my MSc in Computer Science and am eager to see how it unfolds. I will provide updates after completing the first module. I can't wait to start the course!

Hey there!
If you still don’t know us, we are [talkd.ai](https://talkd.ai), an open-source organization that is maintaining Dialog, a project focused on letting you easily deploy any LLM that you want (currently any of those available in the Langchain and partner libraries - we will cover more on that later).
Today, we are very grateful for announcing two things:
1. This is our first official public release, our "Numero Uno" and a starting point to this adventure that will be long and fun.
2. Now it's official: We got accepted in the GitHub Accelerator 2024 AI Cohort - a Cohort full of amazing people that started on April 22nd.
## What is the GitHub Accelerator?
The GitHub accelerator is an accelerator that is running its second cohort in a slightly different approach from the usual: it focuses on making open-source sustainable and helping maintainers find sustainable ways to fund their work full-time on the projects.
During the accelerator, you will be connected to references from fields such as AI, InfoSec, Successful Open Source maintainers, investment funds, and many other professionals who will guide you through the many possibilities of open-source funding.
The project also provides you a stipend for 10 weeks, allowing you and your team to be full-time focused on the development of software and communications of your project, credits on OpenAI and Microsoft Azure.
## Back to the project's history: How did the project start?
The project started to help us ([Thiago Avelino](https://github.com/avelino) and I) create chat experiences that resembled human behavior in answering frequently asked questions inside our contexts (Avelino inside Buser and my context of wanting to learn more about LLM deployments and maintenance).
Still, as the project grew, our contexts changed a lot, as the necessity for different techniques, retrievers, optimizations, and plugins
Nowadays, the project allows you to deploy any model that respects Langchain LCELs or our libraries' chain model, you can choose which one to maintain and set up from there.
The process of getting to where we are right now involves lots of people, but I would like to specially:
- [Luan Fernandes](https://github.com/lgabs/) - our Langchain specialist and long-time contributor
- [Walison Filipe](https://github.com/walison17/) - our FastAPI master and testing guru
- Gregg and Kevin from the GitHub Accelerator - on helping us improve our software through communications, mentorship, invaluable resources and connections
- Andreas, Alicia, Namee, and Jurgen - you have amazing projects and invaluable lessons on improving pitching.
## What can I do with talkd.ai/dialog?
[talkd.ai/dialog](https://github.com/talkdai/dialog) lets you deploy any LLM that you want (with the code already adapted to the LCEL or AbstractLLM models) in 5 minutes.
With a simple `docker-compose up` you have sample data and a sample prompt up and running.
If you want to customize, you can use our library: [dialog-lib](https://github.com/talkdai/dialog-lib), to implement custom RAGs and Retrievers. We are fully integrated with SQLAlchemy, PGVector, Anthropic, and OpenAI.
Here is our quick product demo to showcase you how simple is to deploy our software:

1,862,673 | HTML Tags You Might Not Know About | Hello Devs👋 In this post, I will share some new and helpful html tags which are added in HTML5 to... | 0 | 2024-05-23T15:44:50 | https://dev.to/dev_kiran/html-tags-you-might-not-know-about-3gk7 | webdev, html, beginners, programming | Hello Devs👋
In this post, I will share some new and helpful html tags which are added in HTML5 to write easy and fast code to create complex, dynamic, engaging, and effective websites.
Lets get started🚀
## dialog
➡ Now you can easily create dialog box or a popup window with `<dialog>` tag. It’s a great way to create custom modal dialogs without relying heavily on **JavaScript**.
```html
<dialog id="myDialog">
<p>This is a dialog box</p>
<button onclick="document.getElementById('myDialog').close()">Close
</button>
</dialog>
<button onclick="document.getElementById('myDialog').showModal()">Open Dialog
</button>
```
## template
➡ The `<template>` tag is used as a container for holding client-side content that you don’t want to display when the page loads. This content can be cloned and inserted into the document using **JavaScript**.
```html
<button onclick="showContent()">Show hidden content</button>
<template>
<h2>Hello, This is Kiran</h2>
<p>Thanks for reading this</p>
</template>
<script>
function showContent() {
let temp = document.getElementsByTagName("template")[0];
let clon = temp.content.cloneNode(true);
document.body.appendChild(clon);
}
</script>
```
## picture
➡ By using `<picture>` tag you can define multiple sources for an image, now the browser choose the best one based on screen size, resolution. This is particularly useful for **responsive** design.
```html
<picture>
<source media="(min-width:650px)" srcset="img_pink_flowers.jpg">
<source media="(min-width:465px)" srcset="img_white_flower.jpg">
<img src="img_orange_flowers.jpg" alt="Flowers" style="width:auto;">
</picture>
```
## meter
➡ The `<meter>` tag can be used for representing a scalar measurement within a known range, like disk usage or the relevance of a query result. It helps to **visually** display values within a range.
```html
<label for="diskUsage">Disk Usage:</label>
<meter id="diskUsage" value="0.6">60%</meter>
```
## output
➡ The `<output>` tag represents the result of a calculation. It can be used with **JavaScript** to display the **result** of a calculation.
```html
<form oninput="result.value=parseInt(a.value)+parseInt(b.value)">
<input type="number" id="a" value="50"> +
<input type="number" id="b" value="25"> =
<output name="result" for="a b">75</output>
</form>
```
## progress
➡ The `<progress>` tag represents the completion progress of a **task**, such as a download or file upload.
```html
<label for="fileProgress">File upload progress:</label>
<progress id="fileProgress" value="70" max="100">70%</progress>

Driven by the dream of revolutionizing software development, they poured their expertise into building an AI unlike any other. Countless trials, setbacks, and late nights fueled by coffee and determination eventually led to a breakthrough – Devin, the world's first AI software engineer, was born.
Devin isn't similar to other coding assistants like [Copilot](https://github.com/features/copilot). While Copilot suggests lines of code, Devin can actually create entire programs by itself based on instructions. It's a game-changer. Imagine a world where intricate software applications materialize at the speed of thought. Devin possesses this very ability. It can churn out lines of clean, efficient code at an astonishing rate, leaving human programmers free to focus on the bigger picture. But Devin's brilliance extends beyond code generation. It's a debugging whiz, able to identify and rectify errors with an almost unnerving precision. Those head-scratching bugs that plague projects for weeks? Devin can sniff them out and eliminate them in a fraction of the time.
[Source](https://youtu.be/fjHtjT7GO1c?si=-2MD9UGm-NnilbSB)
Imagine this scenario: David, a lead developer, is working on a complex application. He outlines the core functionality to Devin, and within minutes, the AI has generated a skeletal framework. David reviews the code, impressed by its efficiency and clarity. He then throws a curveball – a new feature needs integration. Devin takes this in stride, researching the necessary libraries and seamlessly incorporating the feature into the existing codebase. As David delves deeper, He encounters a logical error. No problem – Devin pinpoints the issue, suggests a fix, and even writes unit tests to ensure the bug is truly squashed. By the end of the day, David has made significant progress, all thanks to Devin's silent yet powerful collaboration.
Devin isn't just an AI; it's a testament to human creativity. It signals a new phase in software development, where humans and machines team up to shape the future, step by step. The potential is vast, and Devin is ready to lead the charge into a new era of innovation.
While the claim of being the "first" AI software engineer is debated, Devin's ability to tackle real-world coding challenges is undeniable. It aced tests where it fixed issues in projects like Django, solving way more problems (almost 14%) than previous AI models like [GPT-4](https://openai.com/research/gpt-4). Devin even surpasses them when they receive hints (like which files to change)! This shows Devin excels at independently understanding and solving complex coding challenges. However, Devin's experience is limited. It's been tested on a small set of projects, so we need to see how it performs with broader coding tasks.

- SafariDriver for Safari
5. Browsers
Selenium can automate any browser that is compatible with the corresponding browser driver, such as Chrome, Firefox, Safari, Edge, and Internet Explorer.
Detailed Flow of Selenium Python Architecture
1.Script Execution: The Selenium script is executed, containing commands like opening a browser, navigating to a URL, and interacting with elements.
2.Python Bindings: These bindings translate Selenium commands written in Python into HTTP requests using the JSON Wire Protocol.
3.WebDriver: Communicates with the appropriate browser driver by sending these HTTP requests.
4.Browser Driver: Converts JSON Wire Protocol commands into browser-specific actions and executes them.
5.Browser Interaction: The browser performs the actions, such as loading a webpage or clicking a button.
6.Response Handling: The browser sends responses back to the browser driver, which then sends them to the WebDriver.
7.Result Return: WebDriver returns the results to the Selenium script through the Python bindings, allowing the script to handle the outcomes and perform further actions.
Integration with Testing Frameworks and CI/CD
Selenium is often integrated with testing frameworks like PyTest or Unittest for better test management and reporting. Additionally, integrating Selenium tests with CI/CD tools like Jenkins or GitHub Actions allows for automated test execution as part of the build process, ensuring new code changes do not introduce bugs.
This architecture allows for efficient and effective web browser automation, making Selenium a powerful tool for web application testing.
A Python virtual environment is a tool that helps to keep dependencies required by different projects in separate places, by creating isolated environments for each of them. This is especially significant for maintaining project dependencies and avoiding conflicts. Here are the key benefits and examples illustrating the significance of using Python virtual environments:
Key Benefits
1. Dependency Management: Different projects might require different versions of the same library. Virtual environments help manage these dependencies without conflicts.
2. Isolation: Each virtual environment is isolated from the others, ensuring that the libraries and dependencies in one environment do not affect another.
3. Portability: Virtual environments can be easily recreated on different machines, ensuring consistent development environments.
4. Clean System: Prevents global installation of packages, keeping the system Python environment clean and uncluttered.
5. Reproducibility: Ensures that the same dependencies are used across different stages of development, testing, and production, aiding in reproducibility of code execution.
Examples
Example 1: Different Django Versions
Imagine you have two projects: Project A and Project B. Project A uses Django 2.2, while Project B uses Django 3.2. Installing these different versions globally would cause conflicts. Here’s how you can handle this with virtual environments:
1. Creating Virtual Environments:
```sh
python -m venv projectA_env
python -m venv projectB_env
```
2. Activating Virtual Environments:
- On Windows:
```sh
projectA_env\Scripts\activate
projectB_env\Scripts\activate
```
- On Unix or MacOS:
```sh
source projectA_env/bin/activate
source projectB_env/bin/activate
```
3. Installing Dependencies:
- For Project A:
```sh
pip install django==2.2
```
- For Project B:
```sh
pip install django==3.2
```
4. Deactivating Virtual Environments:
```sh
deactivate

**Randomization**:- Computers are deterministic(we are not considering malfunctions etc). They will do what we ask them to do. They can't generate random outputs, even the AI. However, we can produce pseudo-random outputs from them by using large data and complex algorithms. Pseudo as we can still find pattern in the data but it will take significant time to reach that. To generate a random number in Python, we need a 'random module'.
**Module**:- Often Python projects get so big that it's not possible to maintain all code in one file. To solve this we create different files for different functionality. In a project, main.py is named as the main module. This file will execute first, and other modules will be called from here.
In Python, we are provided with many in-built modules. We save memory by including only those which are required in our program.
To include a python module, we will have to import it into the file where we want to use it.
**List**:- It's a data structure(way of arranging data). Its syntax is: list_name = [value1, value2]. Each value in it is arranged in order and provided a unique number called an index. The index starts from 0 and is assigned to the leftmost value. We add +1 as we move to the right.
To access the value from the list we write:
list_name[index_of_value] >>value
eg list=[a,b,c,d]
list[0] = a , list[2] = c , list[-1] = d
We can also lists inside a list. eg list=[[a,b,c],[1,2,3]]
list[0][1] = b
String:- like lists, in string, each character is also assigned a unique index.
eg string = "ABC" string[0] >>"A"
Functions I learned today:-
1. random.randint(a,b) -This will generate a random number between a and b, including a & b.
2. random.choice(list) -This will return a random value from the list.
3. list.append(x) - This will add value x at the end of the list. list[-1] = x
4. list.insert(i,x) - This will insert value x at index i, shift the previous value to right(will change its index also)
Program_for_today: Rock, paper and scissors

1,862,980 | How to build a Content Hub with a headless CMS | Why would you listen to music on Spotify instead of a tape recorder? Well, because Spotify enables... | 0 | 2024-05-23T15:00:09 | https://dev.to/momciloo/how-to-build-a-content-hub-with-a-headless-cms-125e | Why would you listen to music on Spotify instead of a tape recorder? Well, because Spotify enables you to manage music, make playlists, and share them across multiple platforms with one system. The same goes for building a content hub with a headless CMS.
What is a [content hub](https://thebcms.com/blog/content-hub-guide)?- a collection of content focused on one topic.
What is a [headless CM](https://thebcms.com/blog/headless-cms-101)S? - a content management that serves as a content repository.
You can do the math by yourself: collection of content + content repository = content database ready to be published and reused.
In other words, a headless CMS is a Spotify (or better said, digital content hub) for your content, brand, teams, strategies, communication, and management.
Ok, I set up your mindset, now, the only thing left is to set up a content hub with a headless CMS.
## Why build a Content Hub with a headless CMS
Content management systems have long been recognized as an integral part of a digital strategy. Is it even possible today to successfully run a quality website without a CMS? The same philosophy can be applied to content hubs. Here are the reasons why your CMS can be the central hub for your digital content:
### Flexibility in content distribution
A headless CMS separates the content from its presentation, meaning the content is stored as data and delivered via APIs. This makes it easier to distribute the same content across different platforms (websites, mobile apps, IoT devices, etc.) without having to separately write it for each one.
### Centralized content management
The goal of a content hub is to break down the silos of content that exist across multiple components. Organizations can have complete visibility and control over all digital assets by centralizing their content management efforts.
### Better security
With content assets centrally located, organizations can more easily secure one or a group of platforms than handle an isolated system that includes content items they’re not sure about.
Using headless as a central hub to manage security protocols within a single system is smoother and safer than trying to manage multiple users across multiple systems which will result in a system with a secure gateway.
Learn more: [Is Headless CMS a secure CMS? A Comprehensive Analysis](https://thebcms.com/blog/headless-cms-secure-cms)
### Integration support is out-of-the-box
Integrating new systems and channels is easiest with an API-first CMS where they don't require building from scratch. This is particularly useful for organizations that use a diverse tech stack or need to connect their content management with CRM systems, e-commerce platforms, job boards, or other digital marketing tools.
Another option that you can use is to build the systems you need within a CMS.
Example: [How to use Headless CMS as your job board CMS](https://thebcms.com/blog/headless-cms-as-job-board-cms)
### Better developer experience and independence
Everything in CMS revolves around balancing the requirements of both editors and developers. Developers can build and maintain different frontends (for web, mobile, kiosks, etc.) using the best technologies suited to each platform. The headless CMS will deliver content via APIs, ensuring that each frontend displays it appropriately.
The great balance between developers' and other teams' needs in an organization you can see in this example: [Composable architecture example: Go headless (best practices)](https://thebcms.com/blog/composable-architecture-example)
### Benefits of having Content Hub with a headless CMS
Before I go to the "how-to" part of the article, here is the list that outlines the key benefits of using a headless CMS for a Content Hub, each explained clearly and simply so that whenever you need it you can take a 👀.
- Flexibility in content distribution: Easily share content across various platforms.
- Centralized content management: Manage all content from one central location.
- Better security: Enhanced security from separating content management from delivery.
- Better developer experience and independence: Developers use their favorite tools. boosting efficiency.
- Scalability: Handles more content traffic easily as needs grow.
- Cost efficiency: Saves money by simplifying backend needs and infrastructure
- Performance: Speeds up content delivery and improves UX.
- Content modeling: Easily define and structure types of content, to your specific needs.
- Multi-language support: Supports delivering content in multiple languages from the same platform.
- Content reusability: Reuse the same content in different contexts without additional platforms.
- Advanced permissions settings: Control who can view, edit, or manage content. Enhancing security and workflow management.
Ok, the quick reminder is done. So let’s go to some practical steps and use cases.
## How to set up a content hub with a headless CMS
Setting up a content hub with a headless CMS involves several key steps to ensure you manage and your content across multiple platforms. Below is a detailed guide on how to set up such a system with BCMS:
### Step 1: Define and design your content model
- **Identify content types**: Determine the kinds of content you need, such as a home page, team member’s permissions and roles, blog, articles, product pages, user profiles, and more.
Here’s how to do that in BCMS:
[BCMS Templates](https://docs.thebcms.com/inside-bcms/templates) are a pre-defined content structure. So when you determine your content needs you are ready to make templates for each content piece.
### Step 2: Structure your content
Design the structure for each content piece with fields that represent different content elements.
For example:
1. **Articles:**
- Title
- Author
- Body
- Published date
- Tags
2. **Authors:**
- Name
- Bio
- Profile picture
Here’s how to do that in BCMS:
As you can see from the video above, BCMS entry is a feature that helps you structure (define) properties for every template created.
The structure of an entry depends on the properties of its template. Every entry will display the properties defined in its template. Aside from the pre-defined meta, each entry has a content area.
Let’s see an example, I’ll use my profile in BCMS to show how content is structured.
In this example, this entry is structured this way:
Pre-defined meta:
- **Title:** The title is pre-defined for a reason because it enables easier finding (in this case my name) Just by searching my name in the CMS, anyone from the organization can see which projects I worked on and track all actions within the system.
Other entries can benefit from a pre-defined title to make them more structured, so you will be able to easily find the entries you need among 10,000 entries.
- Role ( old and new members, can have insights what is my job, or for what questions they need to contact me).
- Profile photo ( so the whole team can be able to see how handsome I am 😎).
Content area:
In this example, the content area serves to customize this entry. Pre-defined metadata is structured the same for all team members, but a content area, in this case, can be used to write my bio or work experience and give more insights about me.
### Categories/Tags Pages
This feature helps organize the content and makes it easy for users to find related topics. Use categories, tags, and other taxonomies to organize your content effectively.
### **Implement search functionality**
Content hubs need search functionality because it improves UX, provides quick access to information, simplifies navigation, improves content discoverability, allows users to find relevant content quickly, and provides valuable insights into user behavior and content performance.
Kinds of search functionality in CMSs:
1. **Basic search:**
Most CMS platforms provide basic search functionality. Configure this to meet your needs.
2. **Advanced search:**
Consider integrating a third-party search service like Algolia or ElasticSearch for more advanced search capabilities.
3. **Faceted search:**
Implement faceted search to allow users to filter content based on different criteria (e.g., date, category, tags).
Search functionality in BCMS:
### Step 2: Integrate the CMS with existing systems
- **Identify integration points**: Determine which systems need to connect with the BCMS, such as CRM systems, E-commerce platforms, or marketing automation tools.
- **Use APIs**: Leverage the [BCMS’s API](https://docs.thebcms.com/inside-bcms/key-manager) to integrate with these systems.
### Step 3: Develop a content delivery infrastructure
- **Select frontend technologies**: Choose technologies for developing the frontend(s) that will consume the CMS content.
BCMS is frontend agnostic so you can let developers in your organization choose your stack. Also, there are some [official integrations](https://docs.thebcms.com/quickstart) with the popular frontend frameworks that can help them make a decision easier.
- **Build frontends**: Develop the frontend applications separate from the CMS, ensuring they can consume the API endpoints provided by the CMS.
- **Ensure performance**: Optimize content delivery with caching, content delivery networks (CDNs), and API calls.
### Step 4: Set up content governance
- **Define workflows:** Create workflows that dictate how content is created, approved, and published. Include roles for content creators, editors, and administrators.
- **Implement roles and permissions**: Configure the CMS to enforce these workflows by setting up appropriate roles and permissions for all users.
Roles and permissions are essential for a content hub because they control who can create, edit, and publish content. This ensures that only authorized users make changes, maintaining content quality and security. Clear roles and permissions also help with teamwork, as everyone knows their responsibilities, making content management more efficient and organized.
### Step 5: Go live
Before going live, conduct testing of the CMS and frontend integrations, including user acceptance testing (UAT) to ensure everything works as expected and after that, you are ready to go live.
## Get prepared for BCMS as your Content Hub
You've seen the reasons, you learned how to set up (B)CMS as a content hub. The only thing left is to give it a try.
So at the very end, I'll leave you with sources that you and other members of your organization may find useful:
- [BCMS documentation](https://docs.thebcms.com/)
- [OpenAPI documentation](https://rest-apis.thebcms.com/bcms-backend/3-0-0)
- [Code source](https://github.com/bcms)
- [BCMS starters](https://thebcms.com/starters) (in case you want to build additional services)
Now you have a list of materials that help you get started and build a content hub for your enterprise, so every member of your team can enjoy the advantages of a centralized content database. | momciloo | |
1,862,198 | Why CSS-in-JS Doesn't Solve Problems | CSS-in-JS has gained significant traction in the web development community over the past few years.... | 0 | 2024-05-23T15:00:00 | https://dev.to/m_midas/why-css-in-js-doesnt-solve-problems-14i9 | webdev, javascript, beginners, css | CSS-in-JS has gained significant traction in the web development community over the past few years. Proponents argue that it offers a modular, scoped, and dynamic way to style components, especially within the context of JavaScript-heavy frameworks like React. However, despite its popularity, CSS-in-JS introduces a range of challenges and complexities that suggest it may not be the silver bullet solution for managing styles in web applications. Here, we'll explore some of the fundamental reasons why CSS-in-JS doesn't necessarily solve the problems it sets out to address.
<img src="https://media.giphy.com/media/v1.Y2lkPTc5MGI3NjExdGdlOTcxMDZseTZlNjZvZGt5aTljdGljaGQxb3hjN2M0M2ZtaGhpMyZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw/g697zr42aee76RqD89/giphy.gif">
## Performance Overheads
One of the primary criticisms of CSS-in-JS is the performance overhead it introduces. Traditional CSS is parsed and applied by the browser very efficiently. CSS-in-JS, however, requires styles to be generated and injected into the DOM at runtime, which can lead to significant performance hits, particularly in large applications. This runtime cost includes parsing JavaScript, generating styles, and manipulating the DOM, all of which can contribute to slower page load times and a less responsive user experience.
## Increased Bundle Size
With CSS-in-JS, styles are typically included in the JavaScript bundle. This means that every component with its associated styles contributes to the overall size of the JavaScript bundle. As a result, applications can become bloated, leading to longer download and parse times. This is a stark contrast to traditional CSS, which can be minified and cached separately, reducing the amount of data transferred and improving overall load times.
## Complexity and Learning Curve
CSS-in-JS introduces a new syntax and set of concepts that developers need to learn. While traditional CSS has a well-established and straightforward syntax, CSS-in-JS solutions often require familiarity with JavaScript template literals, tagged templates, and sometimes even CSS preprocessors like Sass. This added complexity can steepen the learning curve for new developers and increase the cognitive load for experienced developers, making the development process more cumbersome.
## Poor Separation of Concerns
One of the foundational principles of web development is the separation of concerns: HTML for structure, CSS for presentation, and JavaScript for behavior. CSS-in-JS blurs these lines by embedding styles directly within JavaScript files. This can lead to harder-to-maintain codebases, as styles are no longer isolated from the logic and structure of the application. When styling rules are mixed with component logic, it can become more challenging to manage and debug issues, especially in larger applications.
## Inconsistent Styling Approaches
CSS-in-JS can lead to inconsistent styling approaches within a codebase. Different libraries and frameworks offer various ways to implement CSS-in-JS, each with its own syntax and conventions. This inconsistency can result in a fragmented codebase where styles are applied in multiple ways, making it harder to enforce a unified design system. Traditional CSS, especially when combined with methodologies like BEM (Block, Element, Modifier) or utility-first CSS frameworks, provides a more consistent and predictable approach to styling.
## Lack of Tooling and Ecosystem Support
While CSS-in-JS solutions have matured, they still lack the extensive tooling and ecosystem support available for traditional CSS. Tools like PostCSS, Autoprefixer, and CSS linting utilities have been developed and refined over years to enhance the CSS development workflow. Although some CSS-in-JS libraries offer plugins and integrations, they often fall short of the comprehensive support and flexibility provided by the broader CSS ecosystem.
## Conclusion
While CSS-in-JS offers some compelling features, such as scoped styles and dynamic theming, it introduces a range of challenges that can negate its benefits. Performance overheads, increased bundle sizes, added complexity, poor separation of concerns, inconsistent styling approaches, and limited tooling support are significant drawbacks that make CSS-in-JS less appealing for many projects.
In many cases, traditional CSS, possibly enhanced with modern methodologies like BEM, utility-first frameworks like Tailwind CSS, or preprocessors like Sass, can provide a more efficient, maintainable, and performant solution. Developers should carefully weigh the pros and cons of CSS-in-JS and consider their specific project requirements before adopting this approach. | m_midas |
1,840,765 | Redirect YAML From Ghost Data Using JQ | A bit ago I realized I needed to generate redirect text for each of my current blog posts on my... | 27,249 | 2024-05-23T14:57:00 | https://dev.to/simplykyra/how-to-find-the-redirect-section-on-your-ghost-account-67 | ghost, yaml, json, jq | A bit ago I realized I needed to generate redirect text for each of my current blog posts on my Casper themed Ghost website. This seemed to be an overwhelming task but after talking it through both my husband and I came up with two potential ideas. Here is his idea that uses the data file, jq, and visual filtering that I implemented, while tired, and shared in case it helps you.
Quick aside: To go over how to find the redirect section through [the Ghost](https://ghost.org) interface you can check out my earlier post in this series `How to Find the Redirect Section on Your Ghost Account`. After this one I'll share an alternative way to do this. If you are looking for my original full post you can check out [Oh No, I Need to Create Redirect Text for All My Posts!](https://www.simplykyra.com/blog/oh-no-i-need-to-create-redirect-text-for-all-my-posts/).
Word of warning I was tired when doing this, it was all new to me, wasn't working, and I easily got frustrated. As such it's a bit of a journey but I figured I'd share my process in case something in it I may have otherwise omitted helps you out.
## Get the Data
To use this method you will need to start with your website data that I got by exporting it from my website through the migration portion of my settings page. I found it by entering my domain and then typing in `/ghost/#/settings/migration`.
## Parse the Data
Once I had my data I needed to extract each of my posts' slugs. We decided to use [`jq`, a lightweight and flexible command-line JSON processor,](https://jqlang.github.io/jq/?ref=simplykyra.com) to get that information but before we did that we first needed to figure out what the command itself, used to parse out that information, should be. To figure it out we opened the data and used `ctrl+f` to look for a slug and then worked my way back up resulting in the following structure. This is the `json` code from the Migration Export part of the Settings with only the information needed extracted:
```
{
"db": [
{
"data": {
"offers": [],
"posts": [
{
"slug": “foo”,
}
]}}]}
```
With the json structure found we next turned to [ChatGPT](https://chat.openai.com/?ref=simplykyra.com) and asked it to create the `jq` query I needed which gave me the command: `jq '.db[].data.posts[].slug' data.json`. I used that to test out the results and further iterated through versions while hoping I was getting closer to what I wanted.
## Downhill
The resulting `yaml` from the command worked when uploaded to localhost but didn't work once uploaded to my main website as I had way too many redirects for the website page to load there. I next went back and forth with ChatGPT constantly trying to fix the `yaml` resulting in, at times, decreasing the number of redirects and a 404 error. In the process I got frustrated and switched over to `json` so I could use the pattern matching mentioned in [Ghost's Implementing redirects](https://ghost.org/tutorials/implementing-redirects//?ref=simplykyra.com#using-regular-expressions) and thus switched over to wanting the `json` output to look something more like:
```
{"from":"^\/(slug)\/$","to":"/blog/$1","permanent":true},
```
## A Command
During this process I was getting frustrated but looking back, at some point, I was using this command where each section's results were piped `|` as input into the next section.
```
cat simply-kyra.ghost.date.json | jq '.db[0].data.posts[] | {"from":"^/(.+)/$","to":"/blog/(.slug)","permanent":true}' | pbcopy
```
Explained below is each section:
- `cat simply-kyra.ghost.date.json`: Displays the contents of the downloaded file from Ghost.
- `jq '.db[0].data.posts[]`: Takes the file's contents and parses out the slugs for each post.
- `{"from":"^/(.+)/$","to":"/blog/(.slug)","permanent":true}'`: Converts the list of slugs to the content `string` I want consisting of this text.
- `pbcopy`: and then sends the output to my clipboard so I can paste it into my actual redirects file and upload back up to my website. Just a heads up this is only a Mac command you'll need to adjust it to something else if you're using a different computer.
## Got It
I kept having trouble with mismatched brackets and the like so I decided to simplify the automated part of this process by switching out the complicated special `string` I wanted outputted and instead padded each slug with several dashes on the left and lots of zeros on the right. I had the idea that I could simply do a find all and replace on the results without worrying about the brackets themselves. With this change the new ChatGPT reply went something like this:
Which resulted in the following command:
```
cat simply-kyra.ghost.date.json | jq -r '.db[].data.posts[] | " ---(.slug)000000"' | pbcopy
```
This command extracts the `slug` field from each post and appends `000000` after it while also prefixing it with a triple dash. For example, if the input JSON contains:
```
{
"db": [
{
"data": {
"offers": [],
"posts": [
{
"slug": "foo"
},
{
"slug": "bar"
}
]
}
}
]
}
```
This command would output:
```
---foo000000
---bar000000
```
And then I'd do two find and replace all commands so the `000000` is replaced with `)\/$","to":"/blog/$1","permanent":true},` and the triple dashes are replaced with `{"from":"^\/(` leading to these results:
```
{"from":"^\/(foo)\/$","to":"/blog/$1","permanent":true},
{"from":"^\/(bar)\/$","to":"/blog/$1","permanent":true},
```
## Warning
During the find and replace portion I happened to notice a page title and realized the posts' section in my data file didn't just include posts but also included all of my pages thus meaning I needed to further mine my file to remove all of the page-related lines that didn't need to be redirected. Luckily I didn't have too many pages but after uploading the new file I realized I missed my about page and it was now redirecting to a location that didn't exist. That said, I'm happy it was just the one page and I was able to fix it by simply renaming the page url (and then fixing the linked menu button) and now it's all good to go... that said, while writing this I realized any previous links to my about post no longer work but at least the menu offers a simple correction for this one. | simplykyra |
1,862,978 | KubeIP v2: Assigning Static Public IPs to Kubernetes Nodes Across Cloud Providers | Kubernetes nodes can benefit from having dedicated static public IP addresses in certain scenarios.... | 0 | 2024-05-23T14:55:38 | https://dev.to/alexeiled/kubeip-v2-assigning-static-public-ips-to-kubernetes-nodes-across-cloud-providers-1a57 | kubernetes, aws, devops, googlecloud | Kubernetes nodes can benefit from having dedicated static public IP addresses in certain scenarios. [KubeIP](https://github.com/doitintl/kubeip), an open-source utility, fulfills this need by assigning static public IPs to Kubernetes nodes. The latest version, KubeIP v2, extends support from Google Cloud's GKE to Amazon's EKS, with a design ready to accommodate other cloud providers. It operates as a DaemonSet, offering improved reliability, configuration flexibility, and user-friendliness over the previous Kubernetes controller method. KubeIP v2 supports assigning both IPv4 and IPv6 addresses.
## Use Cases
### Gaming Applications
In gaming scenarios, a console may need to connect directly to a cloud VM to minimize network hops and latency. Assigning a dedicated public IP to the gaming server's node allows the console to connect directly, improving the gaming experience by reducing latency and packet loss.
### Whitelisting Agent IPs
If you have multiple agents or services running on Kubernetes that require direct connections to an external server and that server needs to whitelist the agents' IP addresses, using KubeIP to assign stable public IPs to the nodes makes this easier to manage than allowing broader CIDR ranges. This is particularly useful when the external server has strict IP-based access controls.
### Avoiding SNAT for Select Pods
By default, pods are assigned private IPs from the VPC CIDR range. When they communicate with external IPv4 addresses, the Amazon VPC CNI plugin translates the pod's IP to the primary private IP of the node's network interface using SNAT (source network address translation). Sometimes, you may want to avoid SNAT for certain pods so that external services see the actual pod IPs. Assigning public IPs to nodes with KubeIP and setting `hostNetwork: true` on the pod spec achieves this. The pod can communicate directly with external services using the node's public IP.
### Direct Inbound Connections and Custom Networking Scenarios
Assigning public IPs to nodes with KubeIP enables a variety of networking scenarios. For instance, you can forward traffic directly to pods running on those nodes, which is useful when you need to expose services on the node to the internet without using a traditional load balancer. An example would be running a web server on a pod and forwarding traffic to it using the node's public IP.
In addition, KubeIP can be used to implement custom networking scenarios that require public IPs on nodes. For example, you could create a custom load balancer that forwards traffic to specific nodes based on the public IP. This flexibility makes KubeIP a powerful tool for testing or deploying custom networking solutions in Kubernetes.
### IPv6 Support
KubeIP extends its functionality beyond IPv4 by supporting the assignment of static public IPv6 addresses to nodes. This feature is increasingly important as the internet continues transitioning towards IPv6 due to the exhaustion of IPv4 addresses. With KubeIP's IPv6 support, you can assign static public IPv6 addresses to your Kubernetes nodes, enabling them to communicate directly with external services over IPv6. This is particularly beneficial for applications that require IPv6 connectivity.
## Conclusion
KubeIP v2 is a powerful tool for assigning static public IPs to Kubernetes nodes across cloud providers. It enables a wide range of use cases, from gaming applications to custom networking scenarios, and supports both IPv4 and IPv6 addresses. The extensible design and simplified DaemonSet model make it easy to deploy and manage in your environment.

These components form the backbone of the digital currency ecosystem, offering users both security and innovation. Let's delve deeper into these aspects to understand their significance and potential impact.
**Deciphering Crypto Wallets:**
Imagine your cryptocurrency holdings as a treasure trove, safeguarded by a digital fortress known as the crypto wallet. These wallets serve as your gateway to the world of digital assets, offering a secure haven for storing, sending, and receiving cryptocurrencies. Here's a closer look at the diverse landscape of crypto wallets:
**1.Hot Wallets:** These wallets are connected to the internet, providing easy access for frequent transactions. While convenient, they are more susceptible to hacking and security breaches. Examples include mobile wallets and desktop wallets.
**2.Cold Wallets:**
Cold wallets, on the other hand, store cryptocurrencies offline, away from the reach of cyber threats. Hardware wallets and paper wallets fall into this category, offering enhanced security for long-term storage.
**3.Multi-Signature Wallets:**
Multi-signature wallets require multiple private keys to authorize a transaction, adding an extra layer of security and mitigating the risk of unauthorized access.
**4.Custodial vs. Non-Custodial Wallets:** Custodial wallets are managed by third-party service providers, while non-custodial wallets give users full control over their private keys. Each option has its advantages and drawbacks, depending on individual preferences and risk tolerance.
Choosing the right crypto wallet involves evaluating factors such as security, convenience, and accessibility. Whether you opt for a user-friendly mobile wallet or a robust hardware wallet, prioritizing the safety of your digital assets is paramount in the ever-evolving landscape of cryptocurrency.
**Crafting Your Own Blockchain:**
Beyond the realm of cryptocurrency lies the revolutionary technology of blockchain, a decentralized ledger with limitless potential. Building your own blockchain opens doors to innovation, enabling you to create custom solutions tailored to specific needs. Here's a roadmap to guide you through the process:
**1.Selecting a Framework:** Choose a blockchain framework or platform that aligns with your project requirements. Ethereum, with its robust smart contract capabilities, is a popular choice for developing decentralized applications (dApps). Alternatively, explore options like Hyperledger Fabric or Binance Smart Chain for specialized use cases.
**2.Defining Consensus Mechanism:** Determine the consensus mechanism that governs your blockchain network, ensuring agreement and validity of transactions among network participants. Popular mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS).
**3.Implementing Smart Contracts:** If your project involves executing programmable logic on the blockchain, smart contracts play a pivotal role. These self-executing contracts automate agreements and transactions, eliminating the need for intermediaries and enhancing transparency.
**4.Testing and Deployment:** Thoroughly test your blockchain network to identify and address any vulnerabilities or inefficiencies. Once satisfied with its performance, deploy the blockchain to the desired network, whether it's a public, private, or consortium blockchain.

তাই এই ব্লগে আমরা Vercel ব্যাবহারের সঠিক উপায় এর কিছু কমন এরর এবং তার সমাধান সম্পর্কে জানার চেষ্টা করব।
**Vercel কি কি উপায়ে ইউজ করা যায়? কোনটার সুবিধা কি?**
Vercel মূলত তিনটি ভিন্ন উপায়ে ব্যবহার করা যেতে পারে:
- **Vercel CLI:** Vercel CLI হল একটি কমান্ড-লাইন ইন্টারফেস। এর মাধ্যমে অনেক সহজে কিছু কমান্ড ব্যাবহার করে প্রোজেক্ট ডিপ্লয় করা যায়।
- **Vercel Dashboard:** এই পদ্ধতিতে ভারসেল এর ওয়েবসাইট থেকে ওয়েব-ভিত্তিক ইন্টারফেস (গ্রাফিকাল ইন্টারফেস) এর মাধ্যমে কিছু প্রসেস অনুসরন করে প্রোজেক্ট ডিপ্লয় করা হয়। এই পদ্ধতিতে CLI এর চেয়ে বেশি ফিচার ইউজ করা যায়।
- **Vercel API:** এটি একটি শক্তিশালী এবং নিয়ন্ত্রণযোগ্য উপায় যায় মাধ্যমে প্রজেক্টগুলির সাথে আরও জটিল ইন্টারঅ্যাকশন করা যায়।
**Vercel CLI দিয়ে Backend প্রোজেক্ট ডিপ্লয় করার সময় কিছু কমন এরর এবং তার সমাধান:**
- **Build error:** এই এররটি প্রোজেক্টের কোডে কোন ত্রুটি থাকার কারণে হয়। বেশির ভাগ সময় কি সমস্যা হয়েছে তা এররে ম্যানশন করা থাকে। এই এররটি সমাধান করার জন্য, কোডটি চেক করে ত্রুটিগুলি ঠিক করতে হবে।
- **Deployment error:** এই এররটি প্রোজেক্টের সেটিংস বা ইনভাইরন্মেন্টের সমস্যার কারণে হয়। অনেক সময় vercel.json ঠিক ভাবে কনফিগার না করার কারনেও এই ধরনের এরর হয়। এই এররটি সমাধান করার জন্য, প্রোজেক্টের সেটিংস এবং ইনভাইরন্মেন্ট গুলো চেক করতে হবে।
- **Runtime error:** এই এররটি প্রোজেক্টের রানটাইম সময়ে কোন সমস্যার কারণে হয়। প্রজেক্টে কোন প্রসেস অনাকাঙ্ক্ষিত ভাবে বন্ধ হলে, ঠিক ভাবে ডাটাবেজ কানেক্ট না হলে, বা কোন আন হ্যান্ডেল্ড রিজেকশন হলে এই এরর হয়। এই এররটি সমাধান করার জন্য, কোডটি চেক করে প্রয়োজনীয় পরিবর্তন এবং ঠিক ভাবে এরর হান্ডেল করতে হবে।
Vercel এ কোন এরর ফেস করলে শুরুতেই `Logs` চেক করতে হবে। `Logs` টা যদি আপনি মনোযোগ সহকারে পড়েন তাহলে `Error` সম্পর্কে ধারনা পেয়া যাবেন। `Logs`-এ সাধারণত Error-এর কারণ এবং কোথায় Error ঘটেছে সে সম্পর্কে তথ্য থাকে।
**Logs-এর কিছু গুরুত্বপূর্ণ অংশ হল:**
- **Error message:** Error message-এ Error-এর সংক্ষিপ্ত বিবরণ থাকে।
- **Stack trace:** Stack trace-এ Error-এর `path` সম্পর্কে তথ্য থাকে, সে পাথে গিয়ে আপনি এরর এর সমাধান করতে পারেন।
- **Environment variables:** Environment variables-এ কোন প্রবলেম হলে এখানে তা দেখানো হয়, আপনি আপনার প্রোজেক্টের `Settings` অধীনে "Environment" ট্যাবটিতে ক্লিক করে Environment variables-গুলি দেখতে এবং সেট করতে পারেন।।
**কিছু নির্দিষ্ট এরর এবং সমাধান:**
- ***`[Error: "Invalid project name"]`** এই এররটি প্রোজেক্টের নামটি সঠিকভাবে সেট না করা হলে হয়। এই এররটি সমাধান করার জন্য, প্রোজেক্টের নামটি সঠিকভাবে সেট করতে হবে।
- ***`[Error: "No build script found"]`** এই এররটি প্রোজেক্টে একটি build script না থাকার কারণে হয়। এই এররটি সমাধান করার জন্য, প্রোজেক্টে একটি build script যোগ করতে হবে।
- ***`[Error: "Missing dependency"]`** এই এররটি প্রোজেক্টে একটি নির্দিষ্ট dependency না থাকার কারণে হয়। এই এররটি সমাধান করার জন্য, প্রোজেক্টে প্রয়োজনীয় dependency যোগ করতে হবে।
- * **`[Vercel Serverless Functions timing out]`** এই এররটি বিভিন্ন কারনে হয়ে থাকে, কোন রিকুয়েস্ট যদি ১০ সেকেন্ডের পরেও রিসল্ভ না হয় তাহলে সাধারনত এই এরর দেয়। তবে আমরা দেখেছি অনেকে মঙ্গডিবিতে `Current IP` সেট করে রাখার জন্য এর প্রবলেম টা হয়, সেক্ষেত্রে `Current IP` ডিলিট করে `allow access from anywhere` সেট করে দিতে হবে।
**vercel.json কিভাবে সেটআপ করবেন?**
vercel এ express এপ্লকেশন run করার জন্য vercel.json ফাইলে কিছু কনফিগারেশন করা লাগে। সেক্ষেত্রে এটাকে টেমপ্লেট হিসাবে ইউজ করতে পারেন।
```json
{
"version": 2,
"builds": [
{
"src": "index.js", // project এর মেইন ফাইল পাথ,
// আমাদের ক্ষেত্রে সাধারণত `dist/server.js` file
"use": "@vercel/node"
}
],
"routes": [
{
// Specify which paths will route to a destination using a regex
"src": "/(.*)",
// Specify the paths' destination
"dest": "index.js" // project এর মেইন ফাইল পাথ,
// আমাদের ক্ষেত্রে সাধারণত `dist/server.js` file
}
]
}
```
**সচারচর করা কিছু ভুলঃ**
- **বিল্ড না করেই ডিপ্লয় করাঃ** এই প্রবলেম টা সাধারণত CLI দিয়ে ডিপ্লয় করার সময় বেশি চখে পরে। প্রজেক্ট বিল্ড না করে ডিপ্লয় করার কারনে প্রজেক্টটি ঠিকভাবে কাজ করেনা বা আপডেট হয় না। তাই প্রতিবার ডিপ্লয় করার পূর্বে বিল্ড করে নিতে হবে।
- **env সেটআপ না করাঃ** cli এর মাধ্যমে প্রজেক্ট ডিপ্লয় করলে সাধারণত env অটোমেটিক ভাবে সেট হয়ে যায়। কিন্তু মাঝে মাঝে সমস্যা দেখা দেয়। তখন আপনাকে প্রজেক্ট সেটিং থেকে ম্যানুয়ালি Environment Variable সেট করে আবার ড়িপ্লয় করতে হবে।
- **Vercel Functions timing out?** ভারসেলে বিভিন্ন কারনে টাইম আউট হতে পারে। অনেক সময় কোন ফাংশন এক্সিকিউট হতে ১০ সেকেন্ডের বেশি সময় নিলে এটা এরর দেয়। তবে আমরা এটা ফ্রিতে ৬০ সেকেন্ড এক্সটেন্ড করতে পারি।
- **Hobby:** 10s (default) - [configurable](https://vercel.com/docs/functions/configuring-functions/duration) up to 60s
- **Pro:** 15s (default) - [configurable](https://vercel.com/docs/functions/configuring-functions/duration) up to 300s
- **Enterprise:** 15s (default) - [configurable](https://vercel.com/docs/functions/configuring-functions/duration) up to 900s
- https://vercel.com/docs/functions/configuring-functions/duration.
অনেক সময় সব কিছু ঠিক ভাবে করার পরেও ভারসেলে ডিপ্লয় করা প্রজেক্ট কাজ করে না। তখন `.vercel` ফোল্ডার টি ডিলিট করে আবার নতুন ভাবে ডিপ্লয় করতে হবে।
**আরও কিছু টিপস:**
- **সমস্যা সমাধানে Vercel documentation পড়ুন বা support center থেকে হেল্প নিতে পারেন।**
- **Vercel community forums এবং Discord server-এ জুক্ত হতে পারেন। এতে ভারসেলের ফিচার সম্পর্কে আপ টু ডেট থাকতে পারবেন।**
- **আপনার প্রোজেক্টগুলি ডেপ্লয় করার আগে, সেগুলি ভালভাবে পরীক্ষা করুন যাতে কোন ত্রুটি না থাকে।**
আশা করি এই ব্লগটি আপনাদের উপকারে আসবে। এখানে আমি কিছু সাধারন সমস্যা নিয়ে আলোচনা করাছি। আপনারা অন্য কোন সমস্যা ফেস করলে কমেন্ট সেকশনে জানাতে পারেন।

1,862,971 | An Absolute Beginner's Guide to package.json | As a general rule, any project that's using Node.js will need to have a package.json file. What is a... | 0 | 2024-05-23T14:44:20 | https://dev.to/briann_bn/an-absolute-beginners-guide-to-packagejson-2c6h | node, npm, javascript, webdev | As a general rule, any project that's using Node.js will need to have a `package.json` file. What is a `package.json` file?
At its simplest, a `package.json` file can be described as a manifest of your project that includes the packages and applications it depends on, information about its unique source control, and specific metadata like the project's name, description, and author.
Let's break down the core parts of a typical `package.json` file:
#### _Specific Metadata: name, version, description, license, and keywords_
Inside a package.json, you'll almost always find metadata specific to the project - no matter if it's a web application, Node.js module, or even just a plain JavaScirpt library. This metadata helps identify the project and acts as a baseline for users and contributors to get information about the project.
Here's an example of how these fields would look in a `package.json `file:
```
{
"name": "metaverse", // The name of your project
"version": "0.92.12", // The version of your project
"description": "The Metaverse virtual reality. The final outcome of all virtual worlds, augmented reality, and the Internet.", // The description of your project
"main": "index.js"
"license": "MIT" // The license of your project
}
```
A `package.json` file is always structured in the `JSON` format, which allows it to be easily read as metadata and parsed by machines.
If needing to format a `package.json` file manually to get your project up and running seems a bit daunting, there's a handy command that will automatically generate a base `package.json` file for you - if you'd like to learn how to use it, take a peek at the `npm init` instructions below!
#### _Understanding and Managing Your Project's Dependencies: dependencies and `devDepenendcies` in your ``package.json`_`
The other majorly important aspect of a `package.json` is that it contains a collection of any given project's dependencies. These dependencies are the modules that the project relies on to function properly.
Having dependencies in your project's `package.json` allows the project to install the versions of the modules it depends on. By running an install command (see the instructions for` npm install` below) inside of a project, you can install all of the dependencies that are listed in the project's `package.json` - meaning they don't have to be (and almost never should be) bundled with the project itself.
Second, it allows the separation of dependencies that are needed for production and dependencies that are needed for development. In production, you're likely not going to need a tool to watch your CSS files for changes and refresh the app when they change. But in both production and development, you'll want to have the modules that enable what you're trying to accomplish with your project - things like your web framework, API tools, and code utilities.
What would a project's` package.json` look like with dependencies and `devDependencies`? Let's expand on the previous example of a `package.json` to include some.
```
{
"name": "metaverse",
"version": "0.92.12",
"description": "The Metaverse virtual reality. The final outcome of all virtual worlds, augmented reality, and the Internet.",
"main": "index.js"
"license": "MIT",
"devDependencies": {
"mocha": "~3.1",
"native-hello-world": "^1.0.0",
"should": "~3.3",
"sinon": "~1.9"
},
"dependencies": {
"fill-keys": "^1.0.2",
"module-not-found-error": "^1.0.0",
"resolve": "~1.1.7"
}

Neste post, vou explorar duas estratégias principais: ocultar slides ou criar novas derivações da apresentação. Qual delas é menos onerosa e mais produtiva?
Ocultar Slides: Simplicidade e Rapidez
Vantagens
1. Rápido e Fácil: Marcar slides como ocultos é uma tarefa simples e rápida. Não preciso criar novas versões do arquivo, o que economiza tempo.
2. Menos Trabalho: Manter uma única apresentação significa que todas as atualizações e melhorias são aplicadas de forma uniforme, evitando duplicidade de esforço.
3. Consistência: Com uma única apresentação, é mais fácil garantir que todas as informações importantes estejam atualizadas em todos os momentos.
Desvantagens
1. Complexidade de Gerenciamento: Gerenciar quais slides devem ser ocultos para diferentes públicos pode se tornar confuso, especialmente se houver muitas variações.
2. Risco de Erro: Há um risco maior de esquecer de ocultar ou mostrar slides específicos, resultando em uma apresentação inconsistente e potencialmente confusa.
Criar Novas Derivações: Personalização e Clareza
Vantagens
1. Personalização: Criar apresentações derivadas permite personalizar cada uma de acordo com as necessidades específicas de cada público. Isso garante que a mensagem seja clara e relevante.
2. Clareza: Cada versão da apresentação é clara e específica, sem a necessidade de gerenciar slides ocultos. Isso facilita a preparação e a apresentação.
3. Preparação: Ajuda-me a me preparar melhor, pois cada versão da apresentação é ajustada para um público específico.
Desvantagens
1. Tempo Consumido: Criar e manter várias versões da apresentação pode ser demorado. Cada nova derivação requer tempo e esforço para ser desenvolvida.
2. Manutenção: Atualizações precisam ser aplicadas a todas as versões, o que pode ser trabalhoso e aumentar a chance de inconsistências.
Minha Recomendação
Para decidir qual abordagem é mais produtiva e menos onerosa, considero os seguintes fatores:
- Número de Variações: Se as variações entre as apresentações para diferentes públicos são mínimas, ocultar slides pode ser a melhor opção.
- Frequência de Atualizações: Se a apresentação precisa ser atualizada frequentemente, manter uma única versão com slides ocultos pode ser mais eficiente.
- Complexidade da Personalização: Se a personalização para cada público é significativa, criar novas derivações pode ser mais produtivo a longo prazo.
Na minha experiência, para apresentações que requerem personalização substancial para diferentes públicos, criar novas derivações é mais produtivo.
Para apresentações com pequenas variações, ocultar slides é menos oneroso e mais eficiente. Avaliar essas variáveis pode ajudar a escolher a estratégia que melhor se adapta às suas necessidades, permitindo que você se concentre em atividades de maior valor. | biosbug |

One of the primary ways nonprofits are leveraging the best AI software is to enhance the effectiveness of their programs. By analyzing data related to program outcomes, beneficiary demographics, and environmental factors, AI can provide valuable insights into what works and what doesn't.
For example, a nonprofit focused on education may use artificial intelligence to analyze student performance data and identify areas where intervention is most needed. By understanding these insights, organizations can tailor their programs to better meet the needs of their target populations.
### **Optimizing Resource Allocation**
Resource allocation is a crucial aspect of nonprofit management, and nonprofit artificial intelligence software is helping organizations optimize this process. By analyzing historical data on fundraising, expenses, and program outcomes, AI can recommend the most effective allocation of resources.
For instance, AI algorithms can identify which fundraising strategies yield the highest returns or which programs have the greatest impact per dollar spent. This enables nonprofits to allocate their limited resources more efficiently, maximizing their impact on the communities they serve.
### **Improving Donor Engagement**
Donors are the lifeblood of many nonprofits, and AI systems are transforming how organizations engage with their supporters. AI-powered analytics can segment donors based on their preferences, behavior, and giving history, allowing nonprofits to personalize their communications and outreach efforts.
For example, artificial intelligence tools can predict which donors are most likely to respond to a particular campaign or which communication channels are most effective for different donor segments. By tailoring their outreach strategies, nonprofits can cultivate stronger relationships with donors and increase their fundraising effectiveness.
### **Strengthening Advocacy Efforts**
Advocacy is a cornerstone of many nonprofit missions, and AI is playing an increasingly important role in shaping advocacy strategies. **[The best AI software can analyze social media trends, news articles, and public sentiment to identify key issues and influencers relevant to a nonprofit's cause](https://medium.com/p/1a1e54097e6b)**.
This information enables organizations to craft more targeted advocacy campaigns and engage with stakeholders more effectively. For example, AI-powered sentiment analysis can gauge public opinion on a particular issue, helping nonprofits tailor their messaging to resonate with their audience.
### **Addressing Ethical Considerations**
While the potential benefits of AI in nonprofits are significant, it's essential to consider the ethical implications of using nonprofit artificial intelligence software in decision-making. Nonprofits must ensure that AI algorithms are transparent, accountable, and free from bias.

This contract... | 0 | 2024-05-23T14:18:38 | https://dev.to/newsinfo/everything-you-need-to-know-about-business-contract-law-2o91 | law | Contract law is considered one of the most important legal documents in business. This contract determines how the employees are hired, how companies work together, and other details. Contract law is fundamental to understanding the business segment.
We have to study various details in business contract law; therefore, in this article, we will examine these contracts in detail. If you want to [learn more](https://clearwaterbusinessattorney.com/contact/tampa-fl-business-law-attorney/) about the contract laws, this article is for you. Let’s begin our discussion about contract laws. Let’s begin our discussion about business contract laws.
**What is a Contract?**
A contract is a legally binding agreement between two parties designed to create mutual obligations that businesses and individuals use to protect their interests. Some contracts outline the specific terms of engagement for a transaction. These agreements can also dictate the legal consequences if an agreement is violated.
These contracts are either written or verbal. Some businesses use written tracts because it is easier for them to refer to later. Written agreements are more straightforward and less ambiguous to enforce, so it is better to have a written contract.
**What is a Contract Law?**
Contract law is a subset that regulates explicitly how contracts are created and enforced. Various laws deal with these aspects, such as how contracts are formed, what a document must contain to be considered as a contract, who is eligible for entering a contract, what the consequences of exiting or violating a contract, and other such things are. These contract laws explain what a contract exists and when it is enforceable.
**What are the Essential Components of a Contract?**
● Offer: There must be a clear and specific offer from one party to another. There is an offering party and an offeror, and there will be particular terms for the offeree.
● Acceptance: There must be apparent acceptance in the contract to avoid confusion among both parties at later stages. Acceptance can be in three forms: words, actions, and performance.
● Consideration: The contract and the value provided to the contract will be considered. Financial considerations would include loans, property, or other services.
These are some of the significant details of the business contract. The contract law mandates that a contract is only valid when there is proper structure and fulfillment of all requirements, such as public policy, consent from the parties, agreement to all terms and conditions, and various such details. | newsinfo |
1,862,911 | Vasectomy Recovery: Tips for a Smooth Healing Process | Considering a vasectomy as a permanent birth control, Vasectomy Brooklyn, New York, is a good option.... | 0 | 2024-05-23T14:16:20 | https://dev.to/newsinfo/vasectomy-recovery-tips-for-a-smooth-healing-process-10gp | vasetomy | Considering a vasectomy as a permanent birth control, [Vasectomy Brooklyn, New York](https://drjonlazare.com/conditions/vasectomy/), is a good option. A vasectomy is a minor surgical procedure that offers a highly effective way to prevent pregnancy. While it's a relatively simple and effective procedure, proper aftercare is crucial for a smooth and comfortable recovery. This short blog explores essential tips to ensure your body heals optimally after a vasectomy.
**What to Expect After Your Vasectomy?**
Following your vasectomy, it's normal to experience some soreness, swelling, and bruising around the scrotum. This discomfort usually peaks within the first 48 hours and gradually subsides over the next week or two. Your doctor will provide specific instructions on caring for the incision site and managing pain.
**Some Critical Questions for a Smooth Recovery:**
1. **How Much Rest Should I Get?**
Rest is vital for Healing. Plan to take it easy for at least 24-48 hours after your procedure. Avoid strenuous activities or lifting heavy objects. As you feel better, gradually increase your activity level, but listen to your body and avoid pushing yourself too hard.
2. **How Can I Manage Pain and Discomfort?**
Your doctor will likely recommend over-the-counter pain relievers like acetaminophen (Tylenol) to manage discomfort. However, avoid medications like ibuprofen or aspirin that can increase bleeding risk. Apply ice packs to the scrotum for short intervals (20 minutes on, 20 minutes off) to reduce swelling and ease pain.
3. **How Do I Care for the Incision Site?**
Maintaining good hygiene is crucial to prevent infection. Follow your doctor's instructions regarding showering or bathing, typically after 24 hours. Keep the incision site clean and dry. Avoid using harsh soaps or lotions in the area. Wear loose-fitting clothing and supportive underwear, like a jockstrap, to minimize irritation and provide support.
4. **When Can I Resume Sexual Activity?**
While you may feel up for intimacy sooner, it's essential to wait for your doctor's approval. Typically, a waiting period of 7-10 days is recommended to allow for Healing. It's necessary to use alternative contraception methods until a semen analysis confirms the absence of sperm in the ejaculate, signifying a successful vasectomy.
5. **When Should I See a Doctor?**
While some discomfort is expected, be alert for signs of infection, such as increased pain, redness, swelling, or fever. If you experience any unusual bleeding, difficulty urinating, or persistent vomiting, consult your doctor immediately.
**Conclusion**
A vasectomy can be a life-changing decision for men seeking permanent birth control. Following these recovery tips and maintaining open communication with your doctor can ensure a smooth and comfortable healing process. Remember, recovery is an individual journey; listen to your body, prioritize rest, and don't hesitate to seek medical advice if needed. | newsinfo |

1,862,909 | The Dangers of DIY Pest Control in College Station: When to Call in the Professionals? | Pests, the unwelcome guests that invade our homes causing absolute havoc! They start small, perhaps... | 0 | 2024-05-23T14:14:34 | https://dev.to/newsinfo/the-dangers-of-diy-pest-control-in-college-station-when-to-call-in-the-professionals-3inj | diy | Pests, the unwelcome guests that invade our homes causing absolute havoc!
They start small, perhaps with a few ants scurrying across the kitchen floor or a lone cockroach darting out from under the refrigerator. But before you know it, they've multiplied, spreading their presence throughout your living spaces.
[Click here](https://backyardcomfortandpestcontrol.com/bryan_pest_control.asp) to know the steps to take when faced with such a situation. Many homeowners resort to the quick fix of DIY pest control. While this may seem like a convenient solution at a first glance, it often comes with its own set of difficulties and dangers.
● One of the primary dangers of DIY pest control is that it provides a temporary fix, addressing the symptoms rather than the root cause of the infestation.
● Many off-the-shelf products contain harsh chemicals that not only pose health risks to humans and pets but also fail to eradicate the problem entirely.
● Additionally, misidentification of pests and improper treatment methods can exacerbate the issue, leading to the worsening of infestations.
● Ultimately, DIY solutions can result in a waste of both time and money, leaving you back at square one.
This is where professional pest control services come into play. Unlike DIY methods, pest control professionals are trained to accurately identify pests and implement targeted treatment plans.
But how do you know it's time to call the professionals? Here are its tell-tale signs:
1. Large Infestations: If you notice a significant increase in pest activity or the presence of large numbers of pests, it's likely time to seek professional help.
2. Persistent Infestations: Despite your best efforts with DIY methods, if the infestation persists or returns shortly after the treatment, it's a sign that professional intervention is necessary.
3. Structural Damage: Pests such as termites and rodents can cause extensive damage to your home's structure over time. If you notice signs of structural damage, it's essential to address the problem promptly with professional assistance.
4. Venomous Pests: Dealing with venomous pests such as spiders or scorpions requires specialized knowledge and equipment. In such cases, it's safest to leave the job to trained professionals.
All in all, while DIY pest control may seem like a cost-effective solution, it often falls short in effectively addressing pest infestations. So by recognizing the early signs of pest infestation and calling the professionals right away, you can ensure the swift and thorough eradication of pests from your home. | newsinfo |
1,862,907 | optimize query in laravel and mysql | Optimizing queries for large datasets in Laravel involves several strategies to improve performance... | 0 | 2024-05-23T14:12:56 | https://dev.to/abir_hossen_aurnob/optimize-query-in-laravel-and-mysql-5fab | laravel, mysql, query, largedata |
Optimizing queries for large datasets in Laravel involves several strategies to improve performance and efficiency. Here are some key techniques you can use:
1. Use Eloquent Efficiently
Select Specific Columns: Only select the columns you need to minimize the amount of data being retrieved.
```
$users = User::select('id', 'name', 'email')->get();
```
Eager Loading: Use eager loading to prevent the N+1 query problem.
```
$users = User::with('posts', 'comments')->get();
```
2. Use Query Builder
For complex queries, the Query Builder can be more efficient than Eloquent.
```
$users = DB::table('users')->where('status', 'active')->get();
```
3. Pagination
Instead of retrieving all records at once, use pagination to load data in chunks.
```
$users = User::paginate(50);
```
4. Indexing
Ensure that your database tables have proper indexes on columns that are frequently queried.
```
Schema::table('users', function (Blueprint $table) {
$table->index('email');
});
```
5. Chunking
For processing large datasets, use chunking to handle records in smaller pieces.
```
User::chunk(100, function ($users) {
foreach ($users as $user) {
// Process each user
}
});
```
6. Caching
Cache the results of frequently run queries to reduce database load.
```
$users = Cache::remember('active_users', 60, function () {
return User::where('status', 'active')->get();
});
```
7. Use Raw Queries for Complex Operations
For very complex queries, using raw SQL can sometimes be more efficient.
```
$users = DB::select('SELECT * FROM users WHERE status = ?', ['active']);
```
8. Optimize Database Configuration
Ensure your database is configured for optimal performance:
- Increase memory limits.
- Tune the buffer/cache sizes.
- Use appropriate storage engines.
9. Profiling and Analyzing Queries
Use Laravel's query log to analyze and profile your queries.
```
DB::enableQueryLog();
// Run your query
$users = User::all();
$queries = DB::getQueryLog();
dd($queries);
```
10. Avoid N+1 Problem
Ensure you are not making additional queries in loops.
```
// Bad: N+1 problem
$users = User::all();
foreach ($users as $user) {
echo $user->profile->bio;
}
// Good: Eager loading
$users = User::with('profile')->get();
foreach ($users as $user) {
echo $user->profile->bio;
}
```
Optimizing a Complex Query
Suppose you need to fetch users with their posts and comments, and you want to optimize this operation:
```
$users = User::select('id', 'name', 'email')
->with(['posts' => function ($query) {
$query->select('id', 'user_id', 'title')
->with(['comments' => function ($query) {
$query->select('id', 'post_id', 'content');
}]);
}])
->paginate(50);
```

1,862,908 | deck.gl for Google Maps API | In my last post, I talked about how to optimize GeoJSON in Google Maps API by using the Data Layer... | 27,491 | 2024-05-23T14:10:00 | https://www.joshgracie.com/blog/deckgl/ | deckgl, googlemaps, javascript, gis | In my last post, I talked about how to optimize GeoJSON in Google Maps API by using the Data Layer and event listeners. This time, I want to talk about how to use deck.gl to render large datasets in Google Maps. deck.gl is a WebGL-powered framework for visual exploratory data analysis of large datasets. It is (mostly) agnostic to the mapping library you use, so it can be used with Google Maps API.
## What is deck.gl?
Per the [deck.gl](https://deck.gl/) website, deck.gl is a GPU-powered framework for visual exploratory data analysis of large datasets. It makes use of WebGL to render large datasets quickly and efficiently. deck.gl is a great tool for visualizing large datasets in a performant way. It is (mostly) agnostic to the mapping library you use, so it can be used with Google Maps API.
In fact, deck.gl has a Google Maps overlay that allows you to render deck.gl layers on top of a Google Map. There are a few steps to get this set up, but it is relatively straightforward.
## Getting Started
To get started with deck.gl and Google Maps API, you will need to install the deck.gl library. You can do this by running the following command:
```bash
npm install deck.gl
```
Once you have installed deck.gl, you can create a new deck.gl layer and add it to your Google Map. Here is an example of how to do this:
```javascript
import { GeoJsonLayer } from '@deck.gl/layers';
...
// Create a new deck.gl layer
// This example creates a GeoJsonLayer that renders a GeoJSON dataset on top of a Google Map
let newLayer = new GeoJsonLayer({
id: 'geojson',
data,
opacity: 0.8,
stroked: true,
filled: false,
extruded: false,
wireframe: true,
getLineColor: [255, 255, 255],
pickable: true
});
```
After creating the layer, you can add it to a GoogleMapsOverlay object and add that overlay to your Google Map. Here is an example of how to do this:
```javascript
import { GoogleMapsOverlay } from '@deck.gl/google-maps';
...
let overlay = new GoogleMapsOverlay({});
overlay.setProps({
layers: [newLayer],
});
overlay.setMap(map);
```
This will add the deck.gl layer to your Google Map. You can customize the appearance of the layer by changing the properties of the GeoJsonLayer object. For example, you can change the color of the lines by changing the getLineColor property.
## Why use deck.gl with Google Maps API?
There are a few reasons why you might want to use deck.gl with Google Maps API. One reason is that deck.gl is optimized for rendering large datasets quickly and efficiently. If you have a large dataset that you want to visualize on a Google Map, deck.gl can help you do this in a performant way.
As we saw in my last post, rendering large datasets in Google Maps API can be slow and inefficient, even with the optimizations we made using the Data Layer. deck.gl can help you render large datasets more quickly and efficiently by using WebGL to render the data on the GPU.
Another reason to use deck.gl with Google Maps API is that deck.gl provides a lot of flexibility and customization options. You can customize the appearance of your deck.gl layers in a variety of ways, such as changing the color of the lines or adding extrusion to the data. This can help you create more visually appealing and informative visualizations of your data.
## Conclusion
In this post, I talked about how to use deck.gl to render large datasets in Google Maps API. deck.gl is a powerful tool for visualizing large datasets quickly and beautifully. By using deck.gl with Google Maps API, you can create visually appealing and informative visualizations of your data. If you have a large dataset that you want to visualize on a Google Map, I would recommend giving deck.gl a try.

1,862,901 | What Should I Do If My Partner Wants Me To Sign A Prenup? | Prenuptial agreements, more commonly known as prenups, have gained a bad reputation mainly due to... | 0 | 2024-05-23T14:07:04 | https://dev.to/newsinfo/what-should-i-do-if-my-partner-wants-me-to-sign-a-prenup-3gpd | prenups | Prenuptial agreements, more commonly known as prenups, have gained a bad reputation mainly due to media content. However, much of it is unwarranted. Many associate the document with a lack of trust and commitment to the marriage. If your partner has asked you to sign a prenup before the wedding, you may feel shocked and even betrayed.
However, there is no reason to feel so. As [stated here](https://rodriguezfamilylawyer.com/divorce/), Prenups can benefit both you and your children. They guarantee a healthier and happier married life and fewer complexities in case things do not go the right way. You can have a family lawyer review the prenup to ensure it works in your family's best interest.
**What to do if your partner wants to sign you a prenup?**
**1. Separate your emotions from practicality.**
It is normal to experience a range of emotions when facing a prenuptial agreement. You may feel misled, insulted, or hurt. However, it is important to separate your feelings from the practicality of the situation.
Instead of seeing a prenuptial agreement as a reflection of your relationship's strength, see it as a tool for financial planning. The goal is to safeguard both parties and maintain equity in unforeseen circumstances.
**2. Determine its benefits.**
When your partner brings up the prenuptial issue, they probably have the partnership's best interests at heart. Even though some people see a prenuptial agreement as divorce preparation, this agreement has several advantages.
First, it promotes earlier financial conversations. It also protects participating parties from one another's debt. Additionally, having a prenuptial agreement may help a couple avoid arguments during a divorce.
**3. Understand their reasons.**
Have an open discussion about your partner's reasons for wanting a prenuptial agreement. Do they worry about safeguarding their assets or company? Do they worry about more debts in the future? Understanding their viewpoint could reduce your anxieties and help make the conversation more productive.
**4. Communicate with your partner.**
It is the time to speak with your spouse once you have gathered sufficient information. If you are willing to sign it, let your partner know, and if not, discuss your concerns with them. You can work out an arrangement with your partner. Seek legal counsel to protect your future if your spouse-to-be asks you to sign a prenuptial agreement.
**5. Wait to sign.**
Never sign a legal document under pressure you do not understand or agree with. Give it a thorough read, and ask queries if anything needs to be clarified. It is essential to know that the prenup terms can also be negotiated.

1,862,899 | Environment Output Variables: Easy and Secure Output Piping | Sharing information across environments has become even easier and more secure with the introduction... | 0 | 2024-05-23T14:05:03 | https://www.env0.com/blog/environment-output-variables-easy-and-secure-output-piping | infrastructureascode, devops, cloudcomputing, cloudpractitioner | Sharing information across environments has become even easier and more secure with the introduction of Environment Output Variables. This new feature simplifies sharing outputs of one environment with another in the same project or workflow, storing them securely on the [env0 platform](https://www.env0.com/).
Using environment outputs enhance our existing [Workflows](https://docs.env0.com/docs/workflows) capability, making it even easier to define and manage complex dependencies, enabling you to:
* Pipe outputs to dependent environments
* Securely share sensitive values as [outputs](https://www.env0.com/blog/terraform-output-variables-in-depth-guide-with-examples)
* Avoid complex scripting or data sources
In this post, we'll dig into what options you had before Environment Output Variables, how the new feature works, and how you can get started today.
What’s New?
-----------
A common practice with Infrastructure-as-Code is to break large configurations into smaller, easier-to-manage environments. However, there will be dependencies between the environments and a need to share information across environments.
For example, an application deployment might require a subnet ID from a network environment and a database connection string from a database environment.
Prior to the introduction of Environment Output Variables, you could share the outputs of one environment with another through a few options. Each option has some potential downsides to consider.
The [Import Variable Plugin](https://docs.env0.com/docs/import-variable-plugin) in particular was the preferred solution on env0 for accessing the outputs of other environments.
However, using the plugin requires the creation and maintenance of an API key. Also, using the plugin ting requires writing a custom flow to add the step into the automation for an environment. Finally, and perhaps more importantly, the plugin couldn’t support sensitive data outputs, meaning you had to select a different solution for sensitive data or mark them as insensitive.
Environment outputs offer a better and more elegant solution, native to env0, which does not require the addition of a custom flow or provisioning an API key.
Moreover, here the output values are stored securely using encryption and secrets management, making support for sensitive data values possible.
Let's dig into how Environment Output Variables work on env0.
How it works
------------
As an example, let's say we have two environments. One deploys a Virtual Network and the other deploys an AKS cluster.
The AKS cluster will need a subnet ID from the network environment. To share this information, we would first define an output in the VPC configuration that has the subnet ID for the AKS cluster to use:
output "aks_subnet_id" {
value = module.network.vnet_subnets_name_id["aks"]
}
In the AKS environment configuration, there would be an input variable that accepts the subnet ID:
variable "vnet_subnet_id" {
type = string
}
When setting up the variables for the AKS environment, we can define the value for the **vnet\_subnet\_id** input variable as the Environment Output **aks\_subnet\_id** from the network environment.
Once the Network environment has been provisioned, the output values will be available, and the AKS environment can be deployed without having to update any variable values.
The output values from the source environment are stored on the env0 platform and secured using AWS Secrets Manager with KMS encryption. This makes Environment Output Variables a safe and secure option even for sensitive values.
Using Outputs with Workflows
----------------------------
Environment Output Variables can be used to share configuration data across environments in a project, but they are especially useful for Workflows. To understand why, let's quickly review what Workflows are.
### What are env0 Workflows
[Workflows](https://docs.env0.com/docs/workflows) in env0 are a declarative approach to describing the relationships between different environments. Each sub-environment in the workflow can reference an existing template or VCS repository housing a configuration.
The workflow itself is stored as a template that projects can use as a golden path to streamline platform creation.
Workflows vastly simplify expressing the sequence, creation, and maintenance of each sub-environment.
Using the declarative nature of Workflows, you can describe the complex relationships between deployments and initiate partial or full runs to create and update sub-environments.
Inside the workflow, the relationship between sub-environments is described using a **needs** block, referencing the sub-environments that the current entry is dependent on for deployment.
Not only does this help with the initial deployment of resources in the proper sequence, but subsequent changes to any sub-environment can initiate a workflow run to update any dependent components.
Now, let’s get back to our earlier example of a Virtual Network and AKS cluster.
Rather than having them as two separate environments in a project, workflows enable you to describe the relationship between each environment and the order in which they are deployed.
environments:
network: 'Virtual Network'
name: 'AKS Network'
templateName: 'AppNetwork'
aks:
name: 'AKS Cluster'
templateName: 'AKSCluster'
needs:
- network
When provisioning the Workflow, env0 creates a graph showing the relationship between sub-environments in the Workflow.
Workflows are truly a massive step forward in describing and managing complex deployments, but until now they did not share configuration data across the sub-environments. That is where Environment Output Variables come in!
### Enter: Environment Output Variables
Workflows define the relationship between sub-environments, codifying what you would have previously expressed through custom scripts or tribal knowledge.
Before Environment Output Variables, passing outputs from one sub-environment needed to be handled by another solution.
This was often accomplished through the Import Variable Plugin or with **terraform\_remote\_state data**. Environment outputs replaces the need to use either of those solutions with a native approach that is simpler and more secure.
So how might Environment Output Variables be used in a workflow?
Here are a few examples:
* Sharing subnet and environment information from a network deployment to an AKS deployment
* Passing a database connection string from a database deployment to an application deployment
* Passing the Kubernetes connection information and credentials to a Helm configuration
One especially tricky deployment is the bootstrapping of a Kubernetes cluster with a tool like ArgoCD or Flux after the cluster has been created. Workflows can assist with sequencing tasks and handling dependencies, and output variables can be used to pass the Kubernetes connection information.
What’s next
-----------
Output variables are a great way to pass configuration data between environments in the same project, but there's more goodness to come.
Importantly, the feature capabilities are not limited to OpenTofu and Terraform. Terragrunt, Pulumi, and CloudFormation are all supported as output sources and all IaC Frameworks on env0 can make use of Environment Output Variables as inputs. Support for Helm and Kubernetes as output sources is coming soon.
For shared infrastructure scenarios, you may want to share output values with environments in different projects or Workflows. For instance, sharing Kubernetes cluster information with multiple applications in separate projects.
Coming soon, we will add the ability for Environment Output Variables to reference outputs in other projects.
We're excited for you to try out Environment Output Variables and listen to your feedback!
We invite you to [schedule a demo](https://www.env0.com/demo-request) to get a better idea of how Workflows and Environment Output Variables - and env0 in general - could streamline and improve your IaC journey. | env0team |

1,862,895 | 5 Biggest Ethical Challenges In AI Development | Artificial intelligence (AI) is everywhere these days, from your phone's virtual assistant to the... | 0 | 2024-05-23T14:04:04 | https://www.techdogs.com/td-articles/trending-stories/5-biggest-ethical-challenges-in-ai-development | ai, aidevelopment, technology | [Artificial intelligence (AI)](https://www.techdogs.com/category/ai) is everywhere these days, from your phone's virtual assistant to the fancy filters on your social media. But hold on there, – with great power comes great responsibility, as Uncle Ben (from Spiderman, not Toy Story) almost definitely said.
AI is like a super-powered toddler – it can be a real game-changer, but it needs some serious guidance. That's where ethical AI comes in, – a fancy way of saying making sure AI is used for good and not, well, like a super-powered toddler with a box of matches.
Here's the gist of some of the biggest challenges ethical AI is facing:
[Source](https://tenor.com/view/toy-story-buzz-lightyear-toy-fly-to-infinity-and-beyond-gif-17474152)
1. **Bias in AI**: Imagine an AI accidentally skipping over your resume because your name is Aisha instead of Ashley. Yikes. We need to make sure AI is fair and unbiased, like a good friend who wouldn't judge you for accidentally calling them by their ex's name.
2. **Black Box AI**: Sometimes, AI algorithms are like mysterious fortune cookies – you get the answer, but you have no idea how it came to that conclusion. This lack of transparency can be a problem. We need to understand how AI makes decisions, like figuring out why your friend keeps getting recommended polka music playlists.
3. **Privacy Issues with AI**: Imagine Big Brother watching your every move, but way creepier because it's a computer program. That's the concern with AI and privacy. We need to strike a balance between cool new tech and keeping our personal information, well, personal.
So, how do we fix these AI woes? There's no magic wand here, but there are ways to make AI development more ethical. Think diverse teams creating the AI, algorithms that can explain themselves better than your grumpy grandpa, and data privacy rules stricter than your mom about your room.
The future of AI is bright, but we need to make sure it's a future that benefits everyone, not just robots who can finally take over those pesky CAPTCHAs.

1,861,148 | How to Target XHR Errors in Cypress | Introduction Hello, I am Miyazawa, an engineer at WESEEK, Inc. I usually develop GROWI, an... | 0 | 2024-05-23T14:00:00 | https://dev.to/weseek-inc/how-to-target-xhr-errors-in-cypress-59cl | cypress, xhr, programming | ## Introduction
Hello, I am [Miyazawa](https://github.com/miya), an engineer at WESEEK, Inc. I usually develop [GROWI](https://growi.org/en/?utm_source=dev+community&utm_medium=referral&utm_campaign=How_to_Target_XHR_Errors_in_Cypress), an **open-source wiki**. Today, I will explain how to deal with XHR errors that occur in [Cypress](https://www.cypress.io/), which is used for visual regression testing of GROWI.
## Error Details
The error content introduced here is circled in red below. The screenshot shows the actual GROWI login screen.
The actual Cypress code in which the error occurred is shown below. Specifically, it is a Cypress [custom command](https://docs.cypress.io/api/cypress-api/custom-commands) to log in by going to `/login`, entering the user name and password registered in advance, and pressing the login button. You can code as `cy.login(username, password)` to use it.
## Error Cause
I believe that the cause is that the user's session data was not saved properly in the browser by trying to move to a page that requires login without waiting for the `/api/v3/login` response that runs when the login button is pressed.
As a test, after pressing the login button (`cy.get('.btnSubmitForLogin').click()`), I added `cy.wait(10000)`, and the login process was successfully performed without any XHR errors.
From the above, I realized that waiting for the response from `/api/v3/login` seems to be a good idea, so I will modify the code accordingly.
## Solution
Cypress has an API called [intercept](https://docs.cypress.io/api/commands/intercept). This API allows spying and stubbing on HTTP requests made within an application.
Since I only need to spy in this case, the code refers to the documentation. The first argument is the method name and the second argument is the URL. You can create an alias using `as`.If you put the alias you created into `cy.wait`, it will wait for `/api/v3/login` to complete.
I put the above code into the custom command causing the error and it worked correctly.

1,862,893 | TASK - 14 | Q-1-> What is the difference between automation and manual testing in software... | 0 | 2024-05-23T13:58:11 | https://dev.to/hariprasath03/task-14-1hhl | **Q-1-> What is the difference between automation and manual testing in software development?**
**<u>Answer</u>**
**Automation Testing**
- In automation testing, the test cases are executed by automated tools.
- Automation testing is much faster than manual testing.
- It requires automation tools and trained employees those have knowledge about coding.
- It is more reliable than manual testing bcoz this testing is done by tools.
- In sometimes, automation testing needs more investment than manual testing bcoz of automation tools.
- Automation testing uses framework like data driven, testng, cucumber etc.
- It is suitable for regression testing, load testing and performance testing.
**Manual Testing**
- In manual testing, the test cases are executed by human resources.
- Manual testing is consume more time.
- It requires only human resources to execute the test cases.
- It is not more reliable than automation testing bcoz human might make mistake in continuous work.
- It is also needs investment to do testing.
- Manual testing doesn't need frameworks.
- It is suitable for exploratory testing, usability testing and adhoc testing.
================================================
**Q-2-> Explore some of the most common automation testing tool available on the market?**
**<u>Answer</u>**
There are many automation tools are running in the market. They are
- Selenium
- Appium
- TestComplete
- Katalon Studio
- Cypress
- Ranorex Studio
- Perfecto
- LambdaTest
- Postman
- SoapUI
- Tricentis Tosca
- Apache JMeter
- Robot Framework
- Applitools
<u>**Selenium**</u>
Selenium is still number one choice among the automation tester for web application. It is an open source and consists of selenium webdriver, selenium grid and selenium IDE.
**Important Features:**
- It supports all programming languages like java, javascript, python, c, c++ etc.
- It supports all browser as well so we can perform cross-browser testing.
- Integration with other frameworks like Testng, Cucumber, Junit etc.
<u>**Katalon Studio**</u>
Katalon Studio is low code and scalable automation testing tool for web, mobile, API and desktop. It is available in both free and paid version.

- Smart debugging UI and test reporting to troubleshoot failures quickly.
**<u>Postman</u>**
Postman is one of the most widely used automation testing tools for API. It allows users to write different kinds of tests, from functional and integration to regression tests, and execute them automatically in CI/CD pipelines via the command line.
**Important Features:**
- Friendly and easy-to-use interface equipped with code snippets.
- Support for multiple HTML methods, Swagger, and RAML formats.
- Test suite creation, executions with parameterization, and debugging.
==================================================
**Q-3-> What is the Cross Browser Testing?**
**<u>Answer</u>**
Cross Browser Testing is a type of compatibility testing which comes under the non-functional testing. The aim of this testing is to ensure the application or software is working as intended when accessed through all browsers.
**Different Browser:**
Using different browsers like google chrome, firefox, microsoft edge etc. we should ensure the software is working properly through most of the browser.
**Different OS Combination:**
In desktop, there are different OS are available. So we have to test the software in most of the OS in desktop.
**Different Device:**
In Current world there are so much of mobiles devices came to competition. So that the software should work in most of the device. For that we are doing the cross browser testing.
================================================
**Q-4-> Write a Blog on TDD and BDD?**
**<u>Answer</u>**
<u>**Test Driven Development**</u>
Test Driven Development is a testing methodology or a programming practice implemented from developer's perspective. A developer writes an automated test case based on the requirements specified in the documents.
These tests are executed, and in some cases, they fail as they are developed before the development of an actual feature. The development team then re-factors the code for the test to pass successfully. TDD can be done by a single developer while writing both tests and application code side by side to complete a feature.
**Benefits of TDD:**
- Reduces the amount of time required for rework.
- Explores the bugs or errors very quickly.
- Encourages the development of cleaner and better design.
- Results in the creation of extensive code that is flexible and easy to maintain.
**<u>Behavioral Driven Development</u>**
Behavioral Driven Development is a testing approach derived from the Test-Driven Development (TDD) methodology. In BDD, tests are mainly based on systems behavior. This approach defines various ways to develop a feature based on its behavior.
**Benefits of BDD:**
- Helps to reach a wider audience through the non-technical language.
- Focuses on how the system should behave from the customer's and the developer's perspective.
- It is cost effective technique.
- Reduces the effort needed to verify the any post-development defects.

1,862,889 | Technical Documentation: Student Attendance Tracking with API Integration for Parental Notifications | Overview This project is designed to track student attendance and integrate with an API to... | 0 | 2024-05-23T13:48:34 | https://dev.to/emmanuelj/technical-documentation-student-attendance-tracking-with-api-integration-for-parental-notifications-1a2 | webdev, programming, python | #### Overview
This project is designed to track student attendance and integrate with an API to notify parents or guardians about their child's absence from school. The system leverages Python, and SQLite for database management, Flask for the web interface, and Twilio API for SMS notifications. The primary goal is to ensure that parents are promptly informed about their child's attendance status, enhancing communication and accountability.
#### Prerequisite
- **Python**: The main programming language used for the entire project.
- **SQLite**: A lightweight, serverless database engine to store student and attendance records.
- **Flask**: A micro web framework for building the web interface.
- **Twilio API**: A communication API used to send SMS notifications to parents/guardians.
#### Project Structure
1. **Database Design**:
- **Students Table**: Stores student details including ID, name, class, and parent's contact information.
- **Attendance Table**: Records daily attendance status for each student.
2. **Web Interface**:
- Built using Flask to manage student data and mark attendance.
- HTML templates for user interaction.
3. **API Integration**:
- Twilio API for sending SMS notifications to parents/guardians.
4. **Business Logic**:
- Functions for managing database operations.
- Logic to determine absent students and trigger notifications.
#### Implementation Steps
##### 1. Setting Up the Project
Initialize the project directory and create a virtual environment:
```sh
mkdir student_attendance
cd student_attendance
python3 -m venv venv
source venv/bin/activate
pip install flask twilio pandas
```
##### 2. Database Setup
Create an SQLite database and define the schema for students and attendance records.
```python
import sqlite3
def create_database():
conn = sqlite3.connect('attendance.db')
cursor = conn.cursor()
cursor.execute('''
CREATE TABLE IF NOT EXISTS students (
id INTEGER PRIMARY KEY,
name TEXT NOT NULL,
class TEXT NOT NULL,
parent_contact TEXT NOT NULL
)
''')
cursor.execute('''
CREATE TABLE IF NOT EXISTS attendance (
id INTEGER PRIMARY KEY,
student_id INTEGER,
date TEXT,
status TEXT,
FOREIGN KEY(student_id) REFERENCES students(id)
)
''')
conn.commit()
conn.close()
create_database()
```
##### 3. Web Interface with Flask
Develop the Flask application to manage student records and mark attendance.
```python
from flask import Flask, request, render_template
import sqlite3
app = Flask(__name__)
def query_db(query, args=(), one=False):
conn = sqlite3.connect('attendance.db')
cursor = conn.cursor()
cursor.execute(query, args)
rv = cursor.fetchall()
conn.close()
return (rv[0] if rv else None) if one else rv
@app.route('/')
def index():
students = query_db('SELECT * FROM students')
return render_template('index.html', students=students)
@app.route('/add_student', methods=['POST'])
def add_student():
name = request.form['name']
class_name = request.form['class']
parent_contact = request.form['parent_contact']
query_db('INSERT INTO students (name, class, parent_contact) VALUES (?, ?, ?)', (name, class_name, parent_contact))
return 'Student added!'
@app.route('/mark_attendance', methods=['POST'])
def mark_attendance():
student_id = request.form['student_id']
date = request.form['date']
status = request.form['status']
query_db('INSERT INTO attendance (student_id, date, status) VALUES (?, ?, ?)', (student_id, date, status))
if status.lower() == "absent":
notify_parent(student_id)
return 'Attendance marked!'
if __name__ == '__main__':
app.run(debug=True)
```
Create the HTML template (`templates/index.html`):
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Student Attendance</title>
</head>
<body>
<h1>Student Attendance</h1>
<form method="post" action="/add_student">
<input type="text" name="name" placeholder="Student Name" required>
<input type="text" name="class" placeholder="Class" required>
<input type="text" name="parent_contact" placeholder="Parent Contact" required>
<button type="submit">Add Student</button>
</form>
<h2>Mark Attendance</h2>
<form method="post" action="/mark_attendance">
<input type="number" name="student_id" placeholder="Student ID" required>
<input type="date" name="date" required>
<select name="status">
<option value="Present">Present</option>
<option value="Absent">Absent</option>
</select>
<button type="submit">Mark Attendance</button>
</form>
</body>
</html>
```
##### 4. Twilio API Integration
Install and set up the Twilio client to send SMS notifications.
```sh
pip install twilio
```
Integrate Twilio into your Flask application.
```python
from twilio.rest import Client
# Twilio configuration
account_sid = 'your_account_sid'
auth_token = 'your_auth_token'
twilio_number = 'your_twilio_number'
client = Client(account_sid, auth_token)
def notify_parent(student_id):
conn = sqlite3.connect('attendance.db')
cursor = conn.cursor()
cursor.execute('SELECT name, parent_contact FROM students WHERE id = ?', (student_id,))
student = cursor.fetchone()
conn.close()
if student:
name, parent_contact = student
message = client.messages.create(
body=f"Dear Parent, your child {name} was absent today.",
from_=twilio_number,
to=parent_contact
)
print(f"Notification sent to {parent_contact}")
```
##### 5. Business Logic
Add logic to manage the database and handle attendance recording and notifications.
```python
def add_student(name, class_name, parent_contact):
conn = sqlite3.connect('attendance.db')
cursor = conn.cursor()
cursor.execute('INSERT INTO students (name, class, parent_contact) VALUES (?, ?, ?)', (name, class_name, parent_contact))
conn.commit()
conn.close()
def mark_attendance(student_id, date, status):
conn = sqlite3.connect('attendance.db')
cursor = conn.cursor()
cursor.execute('INSERT INTO attendance (student_id, date, status) VALUES (?, ?, ?)', (student_id, date, status))
conn.commit()
conn.close()
if status.lower() == "absent":
notify_parent(student_id)
```
### Discussion and Opinion
#### Benefits
1. **Enhanced Communication**: The integration of SMS notifications ensures that parents or guardians are promptly informed about their child's attendance status. This real-time communication can help parents take immediate action if necessary.
2. **Accountability**: By automating the notification process, the system ensures that no absences go unnoticed. This can significantly improve student accountability and attendance rates.
3. **Scalability**: The use of a web-based interface and an API for notifications means the system can be easily scaled to accommodate a larger number of students and additional functionalities in the future.
4. **Ease of Use**: The simple web interface built with Flask allows for easy interaction, making it accessible for school administrators without requiring extensive technical knowledge.
#### Potential Challenges
1. **Data Privacy**: Handling and storing personal information, especially contact details, requires strict adherence to data privacy regulations. Ensuring secure storage and transmission of data is crucial.
2. **Reliability**: The system's reliance on external APIs like Twilio means that its functionality depends on these services' availability and reliability. Any downtime or issues with the API can disrupt notifications.
3. **Initial Setup**: The project involves several steps, including configuring the database, setting up the Flask application, and integrating with the Twilio API. This initial setup might require technical expertise.
#### In Summary
The project to track student attendance with API integration for parental notifications provides a robust solution to enhance school-parent communication and student accountability. By leveraging modern web technologies and communication APIs, the system offers a scalable and efficient way to manage attendance and ensure that parents are always informed about their child's attendance status.
However, it is essential to address potential data privacy challenges and external services' reliability. With careful planning and implementation, this project can significantly benefit educational institutions by improving attendance tracking and fostering better communication between schools and parents. | emmanuelj |

<Enter>
Welcome to a new article in a series of [Swift 101 notes](https://dev.to/silviaespanagil/swift-101-getting-into-ios-development-gji) 📝 I did while learning the language and I decided to share them because why not?.
If you're new to Swift or interested in learning more about this language, I invite you to follow my series!🙊
In this chapter, I'll be sharing a little bit about `Basic Operators in Swift`.
___
In the [last chapter](https://dev.to/silviaespanagil/swift-101-understanding-types-variables-and-constants-l9h), we discussed constants and variables, which store values for us to use in our code.
When working with these values, we often need them to interact with each other. So, how do we accomplish this?
✨ Enter operators✨
Operators are special symbols that enable us to perform various operations on our variables. These operations can assign or change the value of a variable, allow us to compare one variable with another, or apply logic in our code.

Even if the "Arithmetic" name sound kinda scary, these operators are pretty simple and easy to understand.
Arithmetic operators are basically symbols that allow us to create mathematical calculations, additions, subtractions, multiplications, and divisions.
| Operation | Action | Example | Result |
| --- | --- | --- | --- |
| Addition + | Addition between two values | var addition = 34 + 4 | print(addition) Output: 38 |
| Subtraction - | Subtract operation between values | var subtraction = 34 - 4 | print(subtraction) Output: 30 |
| Multiplication * | Multiplication of values | var multiplication = 30 * 2 | print(multiplication) Output: 60 |
| Division / | Division calculation | var division = 30 / 2 | print(division) Output: 15 |
And yes, the logic says that this kind of operator only works with numeric types. However, Swift also allows us to do an addition operation with String-type variables. This is called **string concatenation** and it will put together in order different strings.
```swift
var magicSpell = "Accio 🪄 "
var object = "Nimbus 2000"
var completeSpell = magicSpell + object
print(completeSpell)
// Output: "Accio 🪄 Nimbus 2000"
```
Please notice that ✨this is not the only way✨ to put two strings together but as this is a `Basic Operators` article we will not get in-depth with other ways to do so.

###Modulo operator
Modulo or remainder operator `%` returns the value that is left after you divide two numbers.
```swift
var moduleA = 10 % 3
var moduleB = 10 % 5
print(moduleA) // 1
print(moduleB) // 0
```
Understanding modulo. If we divide `10 / 3` the quotient is `3` with a remainder of `1`. This means that if we do `10 % 3`, the result is `1`.
Similarly, if we divide `10 / 5` the quotient is `2` which is already a whole number, meaning that there is no remainder from the operation. Therefore, 10 % 5 results in 0.
For me, this was one of the hardest operators to understand🤦🏽♀️, so I wrote down an example that helped me:
Imagine we have ten apples 🍎🍎🍎🍎🍎🍎🍎🍎🍎🍎 and there are three very hungry people, so we want to share the apples between all of us.
🧑🎤 - 🍎🍎🍎
👨🎤 - 🍎🍎🍎
👩🎤 - 🍎🍎🍎
If we want all of us to have the same amount of apples, we will each eat three apples. And there will be an extra apple 🍎 all lonely without a human to eat it. Well, that apple is the module of the first ten! Is the remainder of `10 % 3`
___
###Assignment and compound operators
This kind of operator will assign a value to a variable or constant.
The mother of the assignment operators is the **equal operator** 🟰. We have already used it in the previous chapter and is the one that says to Swift this value should be assigned to this variable or constant
```swift
var variableName: <Variable Type> = <Initial value>
var anotherVariable: <Variable Type>
```
However, the equal operator can be mixed with the arithmetic operators so it does a mathematical calculation and assign the value at the same time.
####Equal `=`
The value from the right will be assigned to the one on the left.
```swift
var a = 10
var b = 100
a = b
print(a) Output: 100
```
####Addition `+=`
The value from the right will be added and assigned to the one on the left.
```swift
var a = 10
var b = 5
a += b
print(a) Output: 15
```
####Subtraction `-=`
The value from the right will be subtracted and assigned to the one on the left.
```swift
var a = 10
var b = 5
a -= b
print(a) Output: 5
```
####Multiplication `*=`
The value from the right will be multiplied and assigned to the one on the left.
```swift
var a = 10
var b = 5
a *= b
print(a) Output: 50
```
####Division `/=`
The value from the right will be divided and assigned to the one on the left.
```swift
var a = 10
var b = 5
a /= b
print(a) Output: 2
```
####Modulo `%=`
It will calculate the modulo and assign it to the variable on the left.
```swift
var a = 10
var b = 5
a %= b
print(a) Output: 0
```
___
###Comparison operators
These operators allow us, as the name states, to compare the value from the left side to the one on the right to check if the condition is true or false.
#### Equal to `==`
The value on the right is equal to the one on the left.
```swift
let a = 10
let b = 100
let c = (a == b)
print(c) Output: false
```
#### Not equal to `!=`
The value on the right is **not equal** to the one on the left.
```swift
let a = 10
let b = 100
let c = (a != b)
print(c) Output: true
```
#### Greater than `>`
The value on the left is **greater** than the one on the right.
```swift
let a = 10
let b = 100
let c = (a > b)
print(c) Output: false
```
#### Less than `<`
The value on the left is **smaller** than the one on the right.
```swift
let a = 10
let b = 100
let c = (a < b)
print(c) Output: true
```
#### Greater or equal to `>=`
The value on the left is **greater than or equal to** the one on the right.
```swift
let a = 100
let b = 100
let c = (a >= b)
print(c) Output: true
```
#### Less or equal to `<=`
The value on the left is **smaller than or equal to** the one on the right.
```swift
let a = 100
let b = 10
let c = (a <= b)
print(c) Output: false
```
___
###Logical operators
Logical operators allow us to check or set some rules based on logic. They compare **two different conditions** and tell us if the comparison between them is true or false.
Logical operators are particularly useful for making decisions in our code, as they enable more complex condition checking.
There are three Logical Operators:
- **And `&&`**: Check if both conditions are true → This **and** that are true
```swift
let a = 10
let b = 10
let c = ((a <= b) && (a == b))
print(c) // Output: true
```
In the example, we check if `a`(10) is less or equal than `b`(10) **and** if `a`(10) is the same as `b`(10). As both of the conditions are true, then the output would be `true`.
- **Or `||`**: Check if at least one of the conditions are true → This **or** that are true
```swift
let a = 10
let b = 100
let c = ((a <= b) || (a == b))
print(c) // Output: true
```
In the example, we check if `a`(10) is less or equal than `b`(100) **or** if `a`(100) is the same as `b`(10). In this case, the first condition is true, but the second is false. As we want to know if one or the other is true, effectively, one of them is true so the output will also be `true`.
- **Not `!`**: Returns true if the operand is false and vice versa
```swift
print(!true) // Output: false
```
In the example, we print the negation of true which is false

#Day Three
## Today's Progress:
-> Make the level out of CSGShapes to give a basic environment to work with.
You can choose color for the material using this tools
-> Add the player to the blockout level and finish setting up the camera and environment.
-> Convert the player into a RigidBody3D and control it with forces.
A RigidBody3D is a 3D physics body that is moved by a physics simulation.
```
extends Node3D
# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta: float) -> void:
if Input.is_action_pressed("ui_accept"):
#Move the character posistion
position.y += delta
if Input.is_action_pressed("ui_left"):
rotate_z(delta)
if Input.is_action_pressed("ui_right"):
rotate_z(-delta)
```
this is the previous code
```
extends RigidBody3D
# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta: float) -> void:
if Input.is_action_pressed("ui_accept"):
apply_central_force(basis.y * delta * 1000.0)
if Input.is_action_pressed("ui_right"):
apply_torque(Vector3(0.0,0.0,100.0 * delta))
if Input.is_action_pressed("ui_left"):
apply_torque(Vector3(0.0,0.0,-100.0 * delta))
```
this is the new code
this code make the character move according to the user input. But instead of transforming the position manually like the previous code, we use apply central force to move the character against the gravity and apply torque to rotate the character
-> Remap some of input to more intuitive controls.
In the project setting there are inputmap tab, this menu allows us to set all the input we need for the game
-> Detect RigidBody collisions with signals and identify bodies with Groups.
Signal let the game objects communicate with each other.

1,862,865 | Function Calling Agent using OpenAI Assistant | What is “function calling” in LLMs? “Function calling” in LLMs refer to its capability to... | 0 | 2024-05-23T13:34:20 | https://dev.to/dheerajgopi/function-calling-agent-using-openai-assistant-2g6m | llm, openai, ai, python | ## What is “function calling” in LLMs?
“Function calling” in LLMs refer to its capability to accept a list of user defined functions (aka tools) and to intelligently choose which “tool” to use based on the prompt provided by the user.
For example, let’s say we have a function `get_weather(location: str)` which provides the current weather based on the location argument. If we pass the get_weather function to the LLM as a tool and ask `“What’s the current weather in Budapest?”`, the LLM can decide to use the get_weather tool instead of responding with incorrect data. In this case, the LLM will simply return the tool name, which is get_weather and the arguments to be passed which is `location = "Budapest"`. Now, we can call the get_weather function using the arguments provided by the LLM (note that LLM cannot call the function for us, we should do that ourselves). After executing the function, pass the return value of the function back to the LLM, and the LLM will provide us with a sensible response.
## So what is a function calling agent?
The general idea of a function calling agent is that, we pass the user query and a list of tools to the LLM, and then call the LLM in a loop until we get the desired response. I know its a vague description :) So, let’s consider an example for better understanding.
Let’s consider a mathematical query for example, since LLMs are generally bad at math.
**Tools provided to the LLM**
- `add(a: float, b: float)`
- `subtract(a: float, b: float)`
- `multiply(a: float, b: float)`
**Query:**
`calculate sum of 1 and 5 and multiply it with the difference of 6 and 3`
## The Agent Loop
The below image will do a better job in explaining the agent loop than writing a long explanation.
You can see that a “conversation” is going on between the app and the LLM inside the agent loop until the LLM can find the result for the user’s query.
## Implementation using OpenAI assistant
Below is the complete code for the OpenAI function calling agent. The explanation for each step has been provided as comments in the code.
Before executing this script, install the required libraries using the below command.
`pip install openai python-dotenv`
Also, store your OpenAI API key in a `.env` file (`OPENAI_API_KEY=your-api-key`).
```python
import os
import sys
from dotenv import load_dotenv
import openai
from openai.types.beta import Assistant, Thread
from openai.types.beta.threads import Run
import json
import logging
# Load env variables (OPENAI_API_KEY)
load_dotenv()
# set log handlers
log_handler = logging.StreamHandler(sys.stdout)
log = logging.getLogger(__name__)
log.addHandler(log_handler)
log.setLevel(logging.INFO)
# initialize OpenAI client
client = openai.OpenAI(api_key=os.getenv("OPENAI_API_KEY"))
# Define the functions which will be the part of the LLM toolkit
def add(a: float, b: float) -> float:
return a + b
def subtract(a: float, b: float) -> float:
return a - b
def multiply(a: float, b: float) -> float:
return a * b

client.beta.threads.messages.create(
thread_id=thread.id, role="user", content=query
)
# The user query is now part of the thread. Now call the LLM (or "run" the thread in OpenAI lingo).
# `create_and_poll` is just a helper method which polls the LLM until a terminal state is reached.
#
# The terminal states are given below:
# "requires_action" - A function call is required. Execute the function and submit the response back.
# The results should be submitted back before the `expires_at` timestamp.
# "completed" - The Run is completed successfully.
# "cancelled" - The run was cancelled (its possible to cancel an in-progress Run).
# "failed" - Failed due to some error.
# "expired" - Run can get expired if we fail to submit function call results before `expires_at` timestamp.

messages = client.beta.threads.messages.list(
thread_id=thread.id,

if run.status == "requires_action":

)
# Submit the function call outputs back to OpenAI
run = client.beta.threads.runs.submit_tool_outputs_and_poll(
thread_id=thread.id, run_id=run.id, tool_outputs=func_tool_outputs
)
# Continue the agent loop.
# Agent will check the output of the function output submission as part of next iteration.
continue
# Handle errors if terminal state is "failed"
else:
if run.status == "failed":
log.error(
f"OpenAIFunctionAgent turn-{turn+1} | Run failure reason: {run.last_error}"
)
raise Exception(
f"Failed to generate text due to: {run.last_error}"
)
# Raise error if turn-limit is reached.
raise MaxTurnsReachedException()
class MaxTurnsReachedException(Exception):
def __init__(self):
super().__init__("Reached maximum number of turns")
if __name__ == "__main__":
log.info(run_math_agent("calculate sum of 1 and 5 and multiply it with difference of 6 and 3"))
```
On executing the above script the LLM will respond with the correct result, which is 18. The LLM will also explain (like a math tutor) each step it took to find the result.
## Shameless plug :)
You can use function calling agents for your application in a much easier way by just adding a python library called [LLMSmith](https://github.com/dheerajgopi/llmsmith) to your list of dependencies. As you might have guessed, I’m the author of that library :).
You can install the library using the following command.
`pip install "llmsmith[openai]"`
Here’s the code for using a function calling agent using `llmsmith`.
```python
import asyncio
import os
from dotenv import load_dotenv
import openai
from llmsmith.agent.function.openai import OpenAIFunctionAgent
from llmsmith.agent.function.options.openai import OpenAIAssistantOptions
from llmsmith.agent.tool.openai import OpenAIAssistantTool
from llmsmith.task.models import TaskInput
# load env vars for getting OPENAI_API_KEY
load_dotenv()
# Define the functions which will be the part of the LLM toolkit
def add(a: float, b: float) -> float:
return a + b
async def run():
# initialize OpenAI client
llm = openai.AsyncOpenAI(api_key=os.getenv("OPENAI_API_KEY"))
# declaration of tools (functions) to be passed into the OpenAIFunctionAgent
add_tool = OpenAIAssistantTool(
declaration={
"function": {
"name": "add",
"description": "Returns the sum of two numbers.",
"parameters": {
"type": "object",
"properties": {"a": {"type": "number"}, "b": {"type": "number"}},
"required": ["a", "b"],
},
},
"type": "function",
},
callable=add,
)
# create the agent
task: OpenAIFunctionAgent = await OpenAIFunctionAgent.create(
name="testfunc",
llm=llm,
assistant_options=OpenAIAssistantOptions(
model="gpt-4-turbo",
system_prompt="you are a math tutor, who explains the solutions to math problems"
),
tools=[add_tool],
max_turns=5,
)
# run the agent
res = await task.execute(TaskInput("Add sum of 1 and 2 to the sum of 5 and 6"))
print(f"\n\nAgent response: {res.content}")
if __name__ == "__main__":
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
```
`llmsmith` can be used for building all sorts of LLM based functionalities (not just agents). Refer the [documentation](https://llmsmith.readthedocs.io/en/latest/index.html) for getting a better idea about the library. The [Examples](https://llmsmith.readthedocs.io/en/latest/examples.html) section has sample codes for implementing RAG using llmsmith and more. | dheerajgopi |

}
```
## **VPC**
The first resource to be created will be the VPC, as it will be needed for most of our resources.
```
terragrunt
└── dev
└── us-east-1
└── amazon_vpc
└── terragrunt.hcl
```
We will use a range of /25, starting with IP 172.35.0.221, to construct our VPC. Four subnets — two public and two private — will be created inside it.
- VPC: 172.35.0.128/25
- Public Subnet 1: 172.35.0.128/27
- Public Subnet 2: 172.35.0.160/27
- Private Subnet 1: 172.35.0.192/27
- Private Subnet 2: 172.35.0.224/27
These code files will be created within:
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
inputs = {
vpc_cidr_block = "172.35.0.128/25"
public_subnet1_cidr_block = "172.35.0.128/27"
public_subnet2_cidr_block = "172.35.0.160/27"
private_subnet1_cidr_block = "172.35.0.192/27"
private_subnet2_cidr_block = "172.35.0.224/27"
availability_zone1 = "us-east-1a"
availability_zone2 = "us-east-1b"
}
terraform {
source = "../../../../modules/amazon_vpc"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
## **IAM PERMISSIONS**
The next thing to be created will be permissions for our resources.
```
terragrunt
└── dev
└── us-east-1
└── aws_roles
└── terragrunt.hcl
```
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
terraform {
source = "../../../../modules/aws_roles"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
## **AWS CERTIFICATE MANAGER**
These are the configurations for applying our certificate; we will generate the certificate and use our domain to validate it.
```
terragrunt
└── dev
└── us-east-1
└── aws_certificate_manager
└── terragrunt.hcl
```
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
terraform {
source = "../../../../modules/aws_certificate_manager"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
## **AWS LOAD BALANCER**
Let’s set up our loadbalancer using Terragrunt now. This will help distribute our traffic and guarantee that our application is highly available.
```
terragrunt
└── dev
└── us-east-1
└── aws_loadbalancer
└── terragrunt.hcl
```
Our Terragrunt setup looks like this. It’s important to note that in order to increase everything’s dynamic nature, we use dependencies between modules.
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
dependency "vpc" {
config_path = "../amazon_vpc"
}
dependency "acm" {
config_path = "../aws_certificate_manager"
}
inputs = {
vpc_id = dependency.vpc.outputs.vpc_id
subnet_id_1 = dependency.vpc.outputs.public_subnet1_id
subnet_id_2 = dependency.vpc.outputs.public_subnet2_id
alb_internal = false
certificate_arn = dependency.acm.outputs.acm_arn
priority_listener_rule = "1"
}
terraform {
source = "../../../../modules/aws_loadbalancer"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
## **AWS TARGET GROUP**
Here we will configure our Target Group with Terragrunt, it is super essential for directing traffic to the correct servers for our application.
```
terragrunt
└── dev
└── us-east-1
└── aws_targetgroup
└── terragrunt.hcl
```
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
dependency "loadbalancer" {
config_path = "../aws_loadbalancer"
}
dependency "vpc" {
config_path = "../amazon_vpc"
}
dependency "acm" {
config_path = "../aws_certificate_manager"
}
inputs = {
vpc_id = dependency.vpc.outputs.vpc_id
subnet_id_1 = dependency.vpc.outputs.public_subnet1_id
subnet_id_2 = dependency.vpc.outputs.public_subnet2_id
certificate_arn = dependency.acm.outputs.acm_arn
listener_ssl_arn = dependency.loadbalancer.outputs.listener_ssl_arn
priority_listener_rule = "2"
health_check_path = "/"
}
terraform {
source = "../../../../modules/aws_targetgroup"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
## **ECS CLUSTER**
In this step we will create our ECS cluster that will host our application.
```
terragrunt
└── dev
└── us-east-1
└── aws_ecs
└── cluster
└── terragrunt.hcl
```
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
terraform {
source = "../../../../../modules/aws_ecs_cluster"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
## **FARGATE AND ECR**
We will construct our fargate service, the repository in the ECR, and a record on our domain as the final configuration file.
```
terragrunt
└── dev
└── us-east-1
└── aws_ecs
└── service
└── terragrunt.hcl
```
terragrunt.hcl
```
include {
path = find_in_parent_folders()
}
dependency "loadbalancer" {
config_path = "../../aws_loadbalancer"
}
dependency "vpc" {
config_path = "../../amazon_vpc"
}
dependency "role" {
config_path = "../../aws_roles"
}
dependency "targetgroup" {
config_path = "../../aws_targetgroup"
}
dependency "cluster" {
config_path = "../cluster"
}
inputs = {
vpc_id = dependency.vpc.outputs.vpc_id
subnet_id_1 = dependency.vpc.outputs.private_subnet1_id
subnet_id_2 = dependency.vpc.outputs.private_subnet2_id
alb_dns_name = dependency.loadbalancer.outputs.alb_dns_name
sg_alb = dependency.loadbalancer.outputs.alb_secgrp_id
target_group_arn = dependency.targetgroup.outputs.tg_alb_arn
cluster_arn = dependency.cluster.outputs.cluster_arn
ecs_role_arn = dependency.role.outputs.ecs_role_arn
instance_count = "1"
container_vcpu = "512"
container_memory = "1024"
aws_account_id = "your account number"
}
terraform {
source = "../../../../../modules/aws_fargate"
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
}
}
```
---
## **APPLY**
After the entire structure has been created, you must apply terragrunt to all directories that contain terragrunt.hcl in the following order.
terragrunt/dev/us-east-1
terragrunt/dev/us-east-1/amazon_vpc
terragrunt/dev/us-east-1/aws_roles
terragrunt/dev/us-east-1/aws_certificate_manager
terragrunt/dev/us-east-1/aws_loadbalancer
terragrunt/dev/us-east-1/aws_targetgroup
terragrunt/dev/us-east-1/aws_ecs/cluster
terragrunt/dev/us-east-1/aws_ecs/fargate
Use this command on terminal to apply. You need use in each directory
`terragrunt apply
`
or in the root folder use:
`terragrunt run-all apply
`
---
## **ECR**
Now we have applied all our infrastructure and our ECR repository has been created, we must upload our image for use in our container.
The image must be downloaded from Docker Hub as an initial step. You can use another image if you prefer or your own from your application.
use this command to download my sonic image:
`docker pull shescloud/sonic-the-hedgehog
`
## **TESTING**
I used a domain I had and our application was temporarily hosted at sonic.shescloud.tech.
**DESTROY**
If you are using it for study, or as a way to complete a test, don’t forget to destroy all resources at the end to avoid unnecessary costs. To delete everything, we will do a process similar to apply, but in the opposite way.
Before deleting everything via terragrunt, you need to access your AWS account, go to the ECR service and delete the image from the repository. After completing this step, you can proceed with destroying each of the repositories.
Now, you must destroy to all directories that contain terragrunt.hcl in the following order.
1. terragrunt/dev/us-east-1/aws_ecs/fargate
2. terragrunt/dev/us-east-1/aws_ecs/cluster
3. terragrunt/dev/us-east-1/aws_targetgroup
4. terragrunt/dev/us-east-1/aws_loadbalancer
5. terragrunt/dev/us-east-1/aws_roles
6. terragrunt/dev/us-east-1/aws_certificate_manager
7. terragrunt/dev/us-east-1/amazon_vpc
8. terragrunt/dev/us-east-1
Use this command on terminal to destroy. You need use in each directory
`terragrunt destroy`
or in the root folder use:
`terragrunt run-all destroy
`
---
## **GITHUB**
You can check the repository with the code on my github:
https://github.com/shescloud/terraform-terragrunt-fargate
---
And that’s it folks! I hope you enjoyed it and get a lot out of this code. See u soon!

These guys... | 0 | 2024-05-23T13:22:56 | https://dev.to/ali_nasir_62c60a7afa3833b/lado-okhotnikov-launched-the-uniteverse-program-within-the-meta-force-metaverse-14bk | Meta Force is a promising project created by a team of techies and cryptocurrency fans. These guys decided to try their hand at GameFi in 2021. And within a year, the platform united more than a million participants from all over the world. The main principles are transparency, distribution, variety of gameplay and maximum use of GameFi's potential.
The first steps are encouraging. There is already a working prototype of the game, and the community is actively growing. The team has attracted strong partners who help with development.
As for the system itself, it is built on the foundation of the Uniteverse software module. The program ensures the viability of the entire platform and in the near future will allow, for example, the digitization of things that the user owns in real life. This solution means that it is possible to combine the possibilities of the gaming universe with the monetization of the gaming experience.
Uniteverse is not just a software module, but a separate ecosystem, the user of which will be able to receive a complete solution to personal requests. This direction will allow you to completely immerse yourself in virtual reality.
“...At Universe, everyone has the right to create, play, learn and improve financial literacy. We adhere to strict principles of complete freedom for all members of our community,” this is how <b> <a href="https://www.cryptowisser.com/nft-marketplace-launched-in-lado-okhotnikovs-meta-force-metaverse//">Lado Okhotnikov </a> </b> sees the mission of his project.
According to the general director of the company, the project is aimed at achieving a fundamentally new level of reality simulation. The developers plan to build a separate world, where users will be able to enjoy high-quality gameplay and take advantage of the maximum benefits offered by the GameFi industry.
The main task that the ecosystem developers set themselves was to create a new format for user interaction with virtual reality.
“In the Meta Force metaverse, we take part in exciting quests, run a business, and collect unique NFTs. We are looking forward to being able to use the full range of opportunities offered by RWA (Real World Assets) technology,” project participants share their impressions.
Particular attention is paid to the problems of blockchain security and transparency. Mr. Lado is a strong proponent of decentralization and anonymity of transactions. According to him, Collection Authentication technology embedded in the Uniteverse platform will help ensure compliance with these ambitious goals.
In addition, the ecosystem architecture is built on the Polygon blockchain. The structure of the metaverse is based on a native token, the capabilities of which are comparable to the functions of the SAND coin of The Sandbox project.
“Forcecoin is the same deflationary instrument as Bitcoin. Its emission is strictly limited by software algorithms and cannot be changed. Over 80% of the issued tokens go to improve the design base of the ecosystem, to develop the Uniteverse platform,” says Lado Okhotnikov.
About Meta Force
The various elements of the ecosystem - tokenomics, a NFT marketplace, and a metaverse are actively developed in Meta Force. A native token will be launched soon. There are plans to present a RWA-based project. The team intends to build a full-fledged virtual reality with unsurpassed graphics on the platform.

1,862,876 | Crafting Perfect Layouts: Mastering CSS Layout Techniques.🚀 | 1. CSS Layout Basics Understanding the basics of CSS layout is crucial for creating structured and... | 0 | 2024-05-23T13:21:02 | https://dev.to/dharamgfx/crafting-perfect-layouts-mastering-css-layout-techniques-3c1h | css, webdev, beginners, programming | **1. CSS Layout Basics**
Understanding the basics of CSS layout is crucial for creating structured and visually appealing web pages. CSS provides various properties and techniques to arrange elements on a page.
**Block and Inline Elements**
- **Block Elements**: Take up the full width available (`<div>`, `<p>`, `<h1>`).
- **Inline Elements**: Take up only as much width as necessary (`<span>`, `<a>`, `<img>`).
*Example:*
```html
<div>This is a block element.</div>
<span>This is an inline element.</span>
```
**Display Property**
- Controls how elements are displayed.
*Example:*
```css
.block {
display: block;
}
.inline {
display: inline;
}
.inline-block {
display: inline-block;
}
```
**2. Floats**
Floats are used to position elements to the left or right, allowing text and other elements to wrap around them.
**Floating Elements**
- Use the `float` property to move elements to the left or right.
*Example:*
```css
.float-left {
float: left;
width: 50%;
}
.float-right {
float: right;
width: 50%;
}
```
**Clearing Floats**
- Use the `clear` property to control the behavior of floating elements.
*Example:*
```css
.clear {
clear: both;
}
```
**3. Positioning**
CSS positioning allows you to place elements precisely on the page.
**Static Positioning**
- The default position of elements.
*Example:*
```css
.static {
position: static;
}
```
**Relative Positioning**
- Position relative to its normal position.
*Example:*
```css
.relative {
position: relative;
top: 10px;
left: 10px;
}
```
**Absolute Positioning**
- Positioned relative to the nearest positioned ancestor.
*Example:*
```css
.absolute {
position: absolute;
top: 20px;
left: 20px;
}
```
**Fixed Positioning**
- Positioned relative to the viewport.
*Example:*
```css
.fixed {
position: fixed;
top: 0;
left: 0;
}
```
**Sticky Positioning**
- Switches between relative and fixed, depending on the scroll position.
*Example:*
```css
.sticky {
position: sticky;
top: 0;
}
```
**4. Modern Layout**
Modern CSS layout techniques like Flexbox and Grid provide powerful tools for designing responsive and complex layouts.
**Flexbox**
- A layout model for arranging elements in a single direction (row or column).
*Example:*
```css
.flex-container {
display: flex;
justify-content: space-around;
}
.flex-item {
flex: 1;
}
```
**CSS Grid**
- A two-dimensional layout system for creating grid-based designs.
*Example:*
```css
.grid-container {
display: grid;
grid-template-columns: repeat(3, 1fr);
grid-gap: 10px;
}
.grid-item {
background-color: lightblue;
}
```
**5. Responsive Design**
Responsive design ensures your web pages look great on all devices by using media queries and flexible layouts.
**Media Queries**
- Apply different styles based on screen size.
*Example:*
```css
@media (max-width: 600px) {
.responsive {
flex-direction: column;
}
}
```
**Flexible Units**
- Use relative units like percentages and `em` for responsive sizing.
*Example:*
```css
.container {
width: 80%;
padding: 2em;
}
```
**Responsive Images**
- Ensure images resize within their containers.
*Example:*
```css
img {
max-width: 100%;
height: auto;
}
```
---
**Conclusion**
Mastering CSS layout techniques is essential for creating structured, responsive, and visually appealing web pages. By understanding the basics of layout, floats, positioning, modern layout techniques like Flexbox and Grid, and responsive design principles, you can build versatile and adaptive web designs. Embrace these skills to enhance the user experience across all devices. | dharamgfx |
1,850,496 | How to Set Up GitHub Actions for Continuous Integration | Introduction In the fast-paced world of software development, ensuring that code is... | 0 | 2024-05-23T13:20:37 | https://dev.to/angelotheman/how-to-set-up-github-actions-for-continuous-integration-2054 | devops, tutorial, github, architecture | ## Introduction
In the fast-paced world of software development, ensuring that code is consistently tested and integrated can be a challenging task. This is where **Continuous Integration (CI)** comes to play.
> CI is a development practice that requires developers to integrate code into a shared repository frequently.
CI automates the process of building, testing and integrating code changes regularly, helping developers to catch issues early and maintain a stable codebase.
GitHub Actions, a powerful feature introduced by GitHub, has revolutionized the way developers automate their workflows. We will explore how to use this tool for setting up CI in your projects.
Here's what we will cover
* Understanding CI and it's benefits
* Introduction to GitHub Actions
* Building CI workflows with Github Actions
* Advanced Techniques and Integration with External Tools
## Benefits of Continuous Integration
There are several benefits to Continuous Integration. These include
* **Early Detection of Bugs**
Continuous Integration facilitates the early detection of bugs by automatically running tests with each code integration, allowing developers to identify and fix issues before they escalate, resulting in more stable software releases.
* **Improved Code Quality**
By ensuring consistent coding standards and practices through automated testing and integration, code quality is checked. This reduces technical debt and ensures the maintainability of the codebase
* **Faster Feedback Loop**
With Continuous Integration, developers receive rapid feedback on their code, enabling them to iterate quickly and address issues promptly leading to faster development cycles.
These are some of the benefits derived from Continuous Integration. Now let's look at using GitHub actions for CI.
## Introduction to GitHub Actions
GitHub Actions serves as a platform for continuous integration and continuous delivery (CI/CD), enabling you to automate the process of building, testing, and deploying your software pipeline.
Here are some uses of GitHub Actions
* You can set up workflows that automatically build and test each pull request submitted to your repository.
* Deploy successfully merged pull requests to your production environment.
* Actions can also be used to package or release projects into the pipeline.
GitHub Actions goes beyond just DevOps and lets you run workflows when other events happen in your repository. For example, you can run a workflow to automatically add the appropriate labels whenever someone creates a new issue in your repository. It has gained popularity for its simplicity and the fact that it is integrated directory into your repository.
Now let's look at the components that make up a GitHub workflow
## Understanding a Github Action Workflow
A workflow is a configurable automated process that will run one or more jobs. A GitHub Actions workflow is defined by a YAML file typically located in the `.github/workflows` directory within your repository.
### Components of a workflow
**Triggers**
These define the event that trigger the workflow. Example, the workflow can start when a user:
* Creates a pull request
* Opens an issue
* Pushes a commit to the repository
etc
**Jobs**
These specify the individual tasks to be executed as part of the workflow. Each job runs sequentially or in parallel and can include multiple steps.
**Steps**
Define the individual actions or commands to be executed within a job. Steps can include tasks like checking out code, running tests, or deploying artifacts.
**Actions**
Actions are reusable units of code that perform specific tasks within a workflow. They can be authored by GitHub or by the community and can be easily integrated into workflows. An action can pull your git repository from GitHub, set up the correct toolchain for your build environment
**Runners**
A runner is a server that runs your workflows when they're triggered. Each runner can run a single job at a time. GitHub provides three runners to run your workflows: _Ubuntu Linux_, _Microsoft Windows_ and _macOS_.
## Build an example workflow
In this section we would set up a simple workflow that **_runs linters_** for Python using pycodestyle. This will help ensure that your Python code adheres to PEP 8 style guidelines and is free of common errors.
### Step-By-Step Guide
1. Create the `.github/workflows` directory at the root of your repository.
2. Inside the directory, create a file `lint.yml`. Go to **Add file** and then write the directory as shown in the image below
After this, commit the changes for it to take effect.
3. Open the `lint.yml` file and add the following code
```yaml
name: Lint Python Code
on: [push, pull_request]
jobs:
lint:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v3
- name: Set up Python
uses: actions/setup-python@v4
with:
python-version: '3.x'
- name: Install Pycodestyle
run: |
pip install pycodestyle
- name: Lint Python files with Pycodestyle
run: |
pycodestyle .
```
### Explanation of the code
* `name`: Defines the name of the workflow as "Lint Python Code".
* `on`: Triggers the workflow on push or pull request events to the main branch. Hence, anytime there's a pull request to merge code or pushing to main branch, this workflow would be triggered.
* `jobs`: Defines a single job named **_lint_** that executes the linting steps.
* `runs-on`: Specifies the environment which would run the workflow, in our case, `ubuntu-latest`.
* `steps`: This section defines the sequential steps within the job:
* `Checkout Code`: Uses the _actions/checkout_ action to check
out the repository code.
* `Set up Python`: Uses the actions/setup-python action to set up
a Python environment.
* `Install Pycodestyle`: Installs the Pycodestyle linter for
Python files.
* `Lint Python Files`: Runs Pycodestyle on the entire repository
to check for PEP 8 compliance.
This workflow ensures that every time code is pushed or a pull request is created, Pycodestyle is automatically run to check for style issues in Python code.
Now let's create a simple python file `hello.py` in our repository with the following code
```python
#!/usr/bin/python3
"""
This is a function file
"""
def hello():
print("hello World")
if __name__ == '__main__':
hello()
```
Now commit and push this code to your repository. The workflow would automatically be triggered since we specified a **push** in the trigger. You would see something equivalent to the image below in the actions tab
Now when there's an error in the workflow (which normally reflects an error in the codebase), it would be marked **red** otherwise, it would check and you'll get something like the image below.
## Debugging a workflow
Here's another python code which should fail in the workflow. We would then learn how to debug or troubleshoot a workflow.
```python
#!/usr/bin/python3
"""
This is a function file
"""
def hello():
print("hello World")
def new():
print("This is me")
if __name__ == '__main__':
hello()
new()
```
This is what we get from the workflow
Now click on the failed workflow to troubleshoot
The logs rightly shows what needs to be done to get the linter to check correctly.
```
./python_with_error.py:6:1: E302 expected 2 blank lines, found 1
./python_with_error.py:9:1: E302 expected 2 blank lines, found 1
./python_with_error.py:10:3: E111 indentation is not a multiple of 4
./python_with_error.py:12:1: E305 expected 2 blank lines after class or function definition, found 1
```
As shown above, there needs to be blank lines added and indentation issues. This gives you a sense of what exactly didn't allow the code to flow in the pipeline.
After fixing the issues with pycodestyle, you should have the equivalent of these
## Advanced CI Workflow Techniques
There are other useful configurations when building a workflow. Let's look at three of them.
### Variables
Variables store non-sensitive information that can change depending on the environment or the context of the workflow.
To add a new variable, navigate to **Settings > Secrets and Variables > Actions**
**Use Cases**
* Setting environment-specific configurations, such as the target
environment (development, staging, production).
* Storing file paths or URLs that might differ between environments.
### Secrets
Secrets store sensitive information securely, such as API keys, passwords, and tokens. They ensure that this information is not exposed in the workflow configuration or logs.
To add a new secret, navigate to **Settings > Secrets and Variables > Actions**
**Use Cases**
* Stores access tokens for third-party services like AWS, Docker Hub,
or email services.
* Database passwords or credentials for accessing secure services.
### Webhooks
Webhooks trigger actions in response to specific events, such as sending notifications to external services.
To add a new webhook, navigate to **Settings > Webhooks**
**Use Cases**
* Sending notifications to Slack, email, or SMS services when a build
fails or succeeds.
* Initiating deployments to environments such as staging or production
when certain conditions are met.
Now let's add a notification to our workflow such that, a SMS is automatically sent to us when our pipeline fails.
Edit the `yml` file with the following code snippet
```yaml
name: CI Pipeline
on: [push, pull_request]
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v3
- name: Set up Python
uses: actions/setup-python@v4
with:
python-version: '3.x'
- name: Install dependencies
run: |
pip install requests pycodestyle
- name: Lint Python files with Pycodestyle
run: |
pycodestyle .
- name: Send SMS Notification
if: failure()
run: |
python - <<EOF
import requests
import json
quicksend_url = "https://uellosend.com/quicksend/"
data = {
'api_key': '${{ secrets.SMS_API_KEY }}',
'sender_id': 'GitHub',
'message': 'CI Pipeline has failed, check the details',
'recipient': '${{ secrets.SMS_RECIPIENT }}'
}
headers = {'Content-type': 'application/json'}
response = requests.post(quicksend_url, headers=headers, json=data)
with open('sms_response.json', 'w') as f:
json.dump(response.json(), f, indent=4)
EOF
```
### Explanation of Code
* We check for a failure of the task to be run then we send aSMS to the user.
* We use [UelloSend](https://uellosend.com/index.php) for the SMS service.
* Secrets are configured for the services in the secrets file within the repository.
Below is the SMS that would be sent should the run or job fail

**TL;DR:** Learn to handle CRUD actions in Syncfusion ASP.NET MVC DataGrid using Fetch requests. This blog covers binding data and performing CRUD actions using Fetch for server-side updates. It includes examples of adding, editing, and deleting records and handling Fetch success and failure events for smooth execution and real-time data consistency.
Fetch is a robust method that is crucial in modern web development. It allows for the asynchronous sending of data to a server for database updates and the retrieval of data from a server without the need to refresh the entire webpage. This makes for a smoother and more efficient user experience.
The Syncfusion [ASP.NET MVC DataGrid](https://www.syncfusion.com/aspnet-mvc-ui-controls/grid "ASP.NET MVC DataGrid"), a feature-rich component designed to handle vast amounts of data, has built-in support for handling CRUD (Create, Read, Update, Delete) operations. These operations are fundamental to any app that involves data manipulation.
However, recognizing our users’ diverse needs, we have also provided an option for users to execute these CRUD operations in the DataGrid using their own Fetch commands. This means that users can interact with their database in a way that aligns with their specific requirements and preferences.
This feature is particularly beneficial as it allows users to seamlessly integrate their server logic with the Syncfusion ASP.NET MVC DataGrid during CRUD operations. As a result, any changes made during these operations can be immediately and accurately reflected in the Grid.
Let’s see how to bind and perform CRUD operations using Fetch request in the ASP.NET MVC DataGrid.
## Render Syncfusion ASP.NET MVC DataGrid
Syncfusion [ASP.NET MVC DataGrid](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/getting-started-mvc "Getting started with ASP.NET MVC DataGrid") is a feature-rich control for displaying data in a tabular format. Its functionalities include data binding, editing, Excel-like filtering, and selection. It also supports exporting data to Excel, CSV, and PDF formats.
Now, let’s see how to render the ASP.NET MVC DataGrid control. Here, we’ve enabled the [paging](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/paging "Paging in ASP.NET MVC DataGrid") and [editing](https://ej2.syncfusion.com/aspnetmvc/documentation/grid/editing/edit "Editing in ASP.NET MVC DataGrid") features for a more interactive user experience. Refer to the following code example.
```js
@Html.EJS().Grid("Grid")
.EditSettings(e => { e.AllowAdding(true).AllowEditing(true).AllowDeleting(true); })
.Columns(col =>{
col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Width("130").Add();
col.Field("EmployeeID").HeaderText("Employee ID").Width("150").Add();
col.Field("CustomerID").HeaderText("CustomerID").Width("70").Add();
col.Field("ShipCity").HeaderText("Ship City").Width("70").Add()
})
.AllowPaging(true)
.AllowSorting(true)
.ActionComplete("actionComplete")
.ActionBegin("actionBegin")
.Toolbar(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" })
.Render()
```
Previously, the **DataSource** was not bound to the DataGrid. However, now we will utilize Fetch requests to bind data to the DataGrid. On the server side, the **GetData** method within the **HomeController** contains the grid’s data source. When the button is clicked, a Fetch request is sent to fetch the data from the server and bind it to the DataGrid control.
```js
public class HomeController : Controller
{
public ActionResult Getdata()
{
IEnumerable DataSource = OrdersDetails.GetAllRecords();
return Json(DataSource);
}
//Create a model class and define the properties.
public class OrdersDetails
{
public OrdersDetails()
{
}
public OrdersDetails(int OrderID, string CustomerId, int EmployeeId, double Freight, bool Verified, DateTime OrderDate, string ShipCity, string ShipName, string ShipCountry, DateTime ShippedDate, string ShipAddress)
{
this.OrderID = OrderID;
this.CustomerID = CustomerId;
this.EmployeeID = EmployeeId;
this.Freight = Freight;
this.ShipCity = ShipCity;
this.Verified = Verified;
this.OrderDate = OrderDate;
this.ShipName = ShipName;
this.ShipCountry = ShipCountry;
this.ShippedDate = ShippedDate;
this.ShipAddress = ShipAddress;
}
//Render data in this method.
public static List<OrdersDetails> GetAllRecords()
{
List<OrdersDetails> order = new List<OrdersDetails>();
int code = 10000;
for (int i = 1; i < 10; i++)
{
order.Add(new OrdersDetails(code + 1, "ALFKI", i + 0, 2.3 * i, false, new DateTime(1991, 05, 15), "Berlin", "Simons bistro", "Denmark", new DateTime(1996, 7, 16), "Kirchgasse 6"));
order.Add(new OrdersDetails(code + 2, "ANATR", i + 2, 3.3 * i, true, new DateTime(1990, 04, 04), "Madrid", "Queen Cozinha", "Brazil", new DateTime(1996, 9, 11), "Avda. Azteca 123"));
order.Add(new OrdersDetails(code + 3, "ANTON", i + 1, 4.3 * i, true, new DateTime(1957, 11, 30), "Cholchester", "Frankenversand", "Germany", new DateTime(1996, 10, 7), "Carrera 52 con Ave. Bolívar #65-98 Llano Largo"));
order.Add(new OrdersDetails(code + 4, "BLONP", i + 3, 5.3 * i, false, new DateTime(1930, 10, 22), "Marseille", "Ernst Handel", "Austria", new DateTime(1996, 12, 30), "Magazinweg 7"));
order.Add(new OrdersDetails(code + 5, "BOLID", i + 4, 6.3 * i, true, new DateTime(1953, 02, 18), "Tsawassen", "Hanari Carnes", "Switzerland", new DateTime(1997, 12, 3), "1029 - 12th Ave. S."));
code += 5;
}
return order;
}
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public int? EmployeeID { get; set; }
public double? Freight { get; set; }
public string ShipCity { get; set; }
public bool Verified { get; set; }
public DateTime OrderDate { get; set; }
public string ShipName { get; set; }
public string ShipCountry { get; set; }
public DateTime ShippedDate { get; set; }
public string ShipAddress { get; set; }
}
}
```
## Retrieving data via Fetch request
We can utilize the **dataSource** property to fetch data from an external source using the Fetch requests and bind it to the ASP.NET MVC DataGrid.
In the following code example, we’ve demonstrated how to fetch data from the server using a Fetch request. Upon successful retrieval, we’ll bind the data to the **dataSource** property within the button click event, using the **onSuccess** event of the Fetch request.
```js
<script>
let button = document.getElementById('btn');
button.addEventListener("click", function (e) {
let fetch= new ej2.base.Fetch("/Home/Getdata", "POST");
fetch.send();
fetch.onSuccess = function (data) {
var grid = document.getElementById('Grid').ej2_instances[0];
grid.dataSource = JSON.parse(data);
};
});
</script>
```
## Performing CRUD actions with Fetch requests
In addition to binding data, you can utilize Fetch requests to handle CRUD (Create, Read, Update, Delete) actions and update your data on the server side. When any grid action is performed, the [actionBegin](https://help.syncfusion.com/cr/aspnetmvc-js2/Syncfusion.EJ2.Grids.Grid.html#Syncfusion_EJ2_Grids_Grid_ActionBegin "actionBegin property of the ASP.NET MVC DataGrid") event is triggered before the action occurs in the grid.
By leveraging the actionBegin event, you can cancel the default CRUD operations by utilizing the **cancel** argument provided by this event. This allows you to call your server-side method dynamically using Fetch and the relevant data received from the actionBegin event to update your server data accordingly.
## Adding a new record with Fetch request
To create a new record using Fetch requests, you can follow these steps:
1.Click on the **Add** icon located in the grid’s toolbar. This action will generate a form within the grid, enabling you to input the necessary details.
2.After entering the details, click the **Update** icon in the toolbar to commit the changes.
3.Throughout this process, the **actionBegin** event is activated. In this event, you can retrieve the **requestType** as **save** and the **action** value as **add** from the argument.
4.Armed with this information, you can cancel the default action and send a Fetch request to execute the add action on the server side.
Refer to the following code example.
```js
//Insert the record.
public ActionResult Insert(OrdersDetails value)
{
OrdersDetails.GetAllRecords().Insert(0, value);
return Json(value);
}
```
Now, we are going to call the **Insert** method from **actionBegin** event through fetch call.
```js
<script>
var flag = false;
function actionBegin(e) {
// Initially the flag needs to be false in order to enter this condition.
if (!flag) {
var grid = document.getElementById('Grid').ej2_instances[0];
// Add and edit operations.
if (e.requestType == 'save' && (e.action == 'add')) {
var editedData = e.data;
// The default edit operation is canceled.
e.cancel = true;
// Here, you can send the updated data to your server using a fetch call.
var fetch= new ej.base.Fetch({
url: '/Home/Insert',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({ value: editedData })
});
fetch.onSuccess = (args) => {
// Flag is enabled to skip this execution when grid ends add/edit action.
flag = true;
// The added/edited data will be saved in the Grid.
grid.endEdit();
}
fetch.onFailure = (args) => {
// Add/edit failed.
// The flag is disabled if the operation fails so that it can enter the condition on the next execution.
flag = false;
}
fetch.send();
}
}
```
In the Fetch success event, you can utilize the Grid’s [endEdit](https://ej2.syncfusion.com/documentation/api/grid/#endedit "endEdit property for the ASP.NET MVC - EJ2 Grid") method for adding and editing and[deleteRecord](https://ej2.syncfusion.com/documentation/api/grid/#deleterecord "deleteRecord method property for the ASP.NET MVC - EJ2") method to delete the corresponding data in the Grid. However, it’s worth noting that invoking these methods trigger the **actionBegin** event again to save the changes in the DataGrid.
To prevent this behavior and control the execution flow, you can employ a flag variable and manage it within the [actionComplete](https://help.syncfusion.com/cr/aspnetmvc-js2/Syncfusion.EJ2.Grids.Grid.html#Syncfusion_EJ2_Grids_Grid_ActionComplete "actionComplete property of the ASP.NET MVC DataGrid") event and Fetch failure events.
Refer to the following code example.
```js
function actionComplete(e) {
if (e.requestType === 'save' || e.requestType === 'delete') {
// The flag is disabled after the operation is successfully performed so that it can enter the condition on the next execution.
flag = false;
}
}
```
## Updating and saving a record using a Fetch request
To edit and save a record using a Fetch request, follow these steps:
1. Select the desired record in the Grid by clicking or using the **Edit** icon in the toolbar. Alternatively, double-click on a row to initiate the editing process for that specific record.
2. In the edit form, make the necessary modifications to the record’s details.
3. Choose the **Update** icon in the toolbar to save the changes.
4. During this process, the **actionBegin** event is triggered. Within this event, retrieve the **requestType** and **action** values from the argument.
5. Check if the **requestType** is **save** and the **action** is **edit** to identify the specific scenario of editing a record.
6. If the conditions are met, cancel the default action by utilizing the appropriate mechanism provided by your DataGrid library. This ensures that the grid’s default behavior for the edit action is bypassed.
7. Finally, construct a Fetch request to call the update method in the controller.
Refer to the following code example.
```js
//Update the record.
Public ActionResult Update(OrdersDetails value)
{
var ord = value;
OrdersDetails val = OrdersDetails.GetAllRecords().Where(or => or.OrderID == ord.OrderID).FirstOrDefault();
val.OrderID = ord.OrderID;
val.EmployeeID = ord.EmployeeID;
val.CustomerID = ord.CustomerID;
return Json(value);
}
```
Now, we are going to call the **Update** method from the **actionBegin** event through Fetch call.
```js
<script>
var flag = false;
function actionBegin(e) {
// Initially, the flag needs to be false in order to enter this condition.
if (e.requestType == 'save' && (e.action == 'edit')) {
var editedData = e.data;
// The default edit operation is canceled.
e.cancel = true;
// Here, you can send the updated data to your server using a Fetch call.
var fetch= new ej.base.Fetch ({
url: '/Home/Update',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({ value: editedData })
});
fetch.onSuccess = (args) => {
// Flag is enabled to skip this execution when the DataGrid ends add/edit action.
flag = true;
// The added/edited data will be saved in the Grid.
grid.endEdit();
}
fetch.onFailure = (args) => {
// Add/edit failed.
// The flag is disabled if operation is failed so that it can enter the condition on next execution.
flag = false;
}
fetch.send();
}
}
```
## Deleting a record using Fetch request
To delete a record using a Fetch request, follow these steps:
1. Select the record you wish to delete in the Grid by clicking on it or using the **Delete** icon in the toolbar.
2. When the record is selected for deletion, the **actionBegin** event is triggered. Within this event, retrieve the **requestType** value from the argument.
3. Check if the **requestType** is **delete** to identify the delete action.
4. If the condition is met, cancel the default action using the appropriate mechanism available in your DataGrid library. This prevents the default behavior of the grid for the delete action.
5. Construct a Fetch request to call the **delete** method in the controller.
6. Configure the Fetch settings, such as the **URL**, **data**, and **success**/**error** handling, based on your specific requirements.
Refer to the following code example.
```js
//Delete the record.
public ActionResult Delete(int key)
{
OrdersDetails.GetAllRecords().Remove(OrdersDetails.GetAllRecords().Where(or => or.OrderID == key).FirstOrDefault());
var data = OrdersDetails.GetAllRecords();
return Json(data);
}
```
Now, we are going to call the **Delete** method from the **actionBegin** event through Fetch call.
```js
<script>
var flag = false;
function actionBegin(e) {
if (e.requestType == 'delete') {
var editedData = e.data;
// The default delete operation is canceled.
e.cancel = true;
// Here, you can send the deleted data to your server using a Fetch call.
var fetch= new ej.base.Fetch ({
url: '/Home/Delete',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({ key: editedData[0][grid.getPrimaryKeyFieldNames()[0]] })
})
fetch.onSuccess = (args) => {
// Flag is enabled to skip this execution when grid deletes a record.
flag = true;
// The deleted data will be removed from the Grid.
grid.deleteRecord();
}
fetch.onFailure = (args) => {
// Delete failed.
// The flag is disabled if the operation fails so that it can enter the condition on the next execution.
flag = false;
}
fetch.send();
}
}
```

So now, let's extend our learning to a broader spectrum by going deep into **variables**.
## What are Variables?
In Vyper, all [variables](https://docs.vyperlang.org/en/stable/scoping-and-declarations.html?highlight=public#scoping-and-declarations) must be explicitly declared with a type. The type of a variable determines the kind of data that it can store. For example, you can declare a variable to store an unsigned integer, a string, or a boolean value.
## Variable types
In Vyper, variables can be broadly categorized into two main types based on their scope and storage:
- Local Variables
- State Variables
## Local variables:
These are temporary variables that exist only within the scope of a function. They are not stored on the blockchain and only exist in memory during the execution of the function.
Local variables are declared within functions and the variables are only accessible within the functions they are declared in.
## Examples:
To better understand how variables are declared in vyper, we shall need to use a series of examples. If you look closely in the examples we provided below, all variables are declared within the function. In the following examples, our aim is to write a smart contract function for adding two numbers:
```python
@external
def addTwo(x: int128, y: int128) -> int128:
result: int128 = x + y
return result
```
To be more concise and idiomatic:
```python
# a simple function to add two numbers x and y
@external
def addTwo(x: int128, y: int128) -> int128:
return x + y
```
We are going to divide the above code into three parts i. e;
1. ```python
@external
```
- `@external`: This is a decorator that specifies the visibility of the function. It indicates that the function `addTwo` can be called from outside the contract. In other words, other smart contracts and external users can invoke this function. This decorator ensures that the function is part of the contract's public interface.
2. ```python
def addTwo(x: int128, y: int128) -> int128:
```
- `def`: This keyword is used to define a function in Vyper (similar to Python).
- `addTwo`: This is the name of the function. It is a descriptive name indicating that the function will add two numbers.
- `x: int128`: This declares a parameter x for the function. The type of x is int128, which means it is a signed 128-bit integer. In Vyper, specifying the type of each variable is mandatory to ensure type safety and prevent overflow/underflow errors.
- `int128`: This type can hold values from `-2^127` to `(2^127) - 1`. It is used for variables that need to store integer values within this range.
- `y: int128`: This declares another parameter y for the function. Like x, y is also of type int128.
- `-> int128`: This part specifies the return type of the function. It indicates that the function will return a value of type int128.
The truth is, Smart contracts on Ethereum are designed to be **deterministic** and do not interact with users in the same way traditional programs do. Therefore, to be able interact with our contract, we need some other tool and that is web3.py. If you don't know how to use web3.py library, please visit my tutorial [here](https://dev.to/mosesmuwawu/how-to-interact-with-smart-contracts-locally-using-web3py-2896) and it will be helpful.
`my_contract.py` file:
```python
from web3 import Web3
# Connect to a local or remote Ethereum node
web3 = Web3(Web3.HTTPProvider('https://data-seed-prebsc-1-s1.binance.org:8545/')) # or your Infura endpoint, etc.
# ABI of the compiled Vyper contract
abi = [
{
"type": "function",
"name": "addTwo",
"stateMutability": "nonpayable",
"inputs": [
{
"name": "x",
"type": "int128"
},
{
"name": "y",
"type": "int128"
}
],
"outputs": [
{
"name": "",
"type": "int128"
}
]
}
]
# Address of the deployed contract
contract_address = web3.to_checksum_address('YOUR_CONTRACT_ADDRESS') # replace with your contract's address
# Create a contract instance
contract = web3.eth.contract(address=contract_address, abi=abi)
# Call the addTwo function
def call_addtwo():
try:
x = int(input('Enter X value: '))
y = int(input('Enter Y value: '))
result = contract.functions.addTwo(x, y).call()
print(f"The result of {x} + {y} is: {result}")
except ValueError:
print('Invalid input. Please enter valid integers for X and Y.')
except Exception as e:
print(f'Error during addition: {e}')
# Call the function to get user input and add the numbers
call_addtwo()
```
And then, run your file and you should get something similar to this:
## State Variables
These are stored on the blockchain. They are part of the contract's state and are persistent across function calls and transactions.
State variables are declared outside of functions, typically at the top of the contract. They are accessible by all functions within the contract and are stored in the contract's storage. Let's have an example to better understand this:
```python
# Define a public variable to store the greeting
greeting: public(String[100])
# Constructor to initialize the greeting
@external
def __init__():
self.greeting = "Hello, World"
# Function to set a new greeting
@external
def set_greeting(new_greeting: String[100]):
self.greeting = new_greeting
# Function to get the current greeting
@external
@view
def get_greeting() -> String[100]:
return self.greeting
```
Here is the detailed explanation of our code:
```python
# Define a public variable to store the greeting
greeting: public(String[100])
```
- `greeting`: This is a state variable defined with the type String[100].
- `State Variable`: This variable is stored on the blockchain, which means its value persists across transactions.
- `public`: The public keyword makes this variable accessible from outside the contract, creating an automatic **getter** function.
- `String[100]`: As already mentioned in previous examples, this specifies that the variable is a string with a maximum length of 100 characters.
```python
@external
def __init__():
self.greeting = "Hello, World"
```
- `init()`: This is the constructor function of the contract, called once when the contract is deployed.
- `self.greeting = "Hello, World"`: This initializes the greeting state variable with the string "Hello, World".
```python
@external
def set_greeting(new_greeting: String[100]):
self.greeting = new_greeting
```
- `set_greeting(new_greeting: String[100])`: This function allows the greeting to be updated.
- `new_greeting: String[100]`: The function takes one parameter, new_greeting, which must be a string with a maximum length of 100 characters.
- `self.greeting = new_greeting`: This updates the greeting state variable with the new value provided.
```python
@external
@view
def get_greeting() -> String[100]:
return self.greeting
```
- `get_greeting() -> String[100]`: This function returns the current value of the greeting variable.
- `@view`: This is one of the available but optional decorators. It indicates that the function does not modify the state of the contract (i.e., it is a read-only function).
- `return self.greeting`: This returns the value of the greeting state variable.
I am very sure now you purely get the context of variables as used in vyperlang. Let's do one more last part of interacting with our smart contract using web3.py library.
> Please note that in the following example, we didn't use environment variables for the sake of brevity. But, i would recommend not to expose your variables by creating a `.env` file for them.
```python
import sys
from web3 import Web3
# Connect to BSC node (Binance Smart Chain)
bsc_node_url = 'https://data-seed-prebsc-1-s1.binance.org:8545/' # Replace with your BSC node URL
web3 = Web3(Web3.HTTPProvider(bsc_node_url))
# Set the private key directly (For demonstration purposes only, do not hardcode in production)
private_key = 'YOUR_PRIVATE_KEY_HERE' # Replace with your actual private key
account = web3.eth.account.from_key(private_key)
# Contract ABI
contract_abi = [
{
"type": "constructor",
"stateMutability": "nonpayable",
"inputs": []
},
{
"type": "function",
"name": "set_greeting",
"stateMutability": "nonpayable",
"inputs": [
{
"name": "new_greeting",
"type": "string"
}
],
"outputs": []
},
{
"type": "function",
"name": "get_greeting",
"stateMutability": "view",
"inputs": [],
"outputs": [
{
"name": "",
"type": "string"
}
]
},
{
"type": "function",
"name": "greeting",
"stateMutability": "view",
"inputs": [],
"outputs": [
{
"name": "",
"type": "string"
}
]
}
]
# Contract address
contract_address = web3.to_checksum_address('YOUR_CONTRACT_ADDRESS') # Replace with your contract's address
# Create contract instance
contract = web3.eth.contract(address=contract_address, abi=contract_abi)
# Function to get the current greeting
def get_greeting():
return contract.functions.get_greeting().call()
# Function to set a new greeting
def set_greeting(new_greeting):
nonce = web3.eth.get_transaction_count(account.address)
tx = contract.functions.set_greeting(new_greeting).build_transaction({
'chainId': 97, # BSC testnet
'gas': 3000000,
'gasPrice': web3.to_wei('5', 'gwei'),
'nonce': nonce,
})
signed_tx = web3.eth.account.sign_transaction(tx, private_key)
tx_hash = web3.eth.send_raw_transaction(signed_tx.rawTransaction)
receipt = web3.eth.wait_for_transaction_receipt(tx_hash)
return receipt
# Main execution
if __name__ == "__main__":
if len(sys.argv) < 2:
print("Usage: python3 interact_with_greeting_contract.py <action> [<value>]")
print("Actions: get, set")
sys.exit(1)
action = sys.argv[1]
if action == "get":
print("Current greeting:", get_greeting())
elif action == "set":
if len(sys.argv) < 3:
print("Usage: python3 interact_contract.py set <value>")
sys.exit(1)
new_greeting = ' '.join(sys.argv[2:])
receipt = set_greeting(new_greeting)
print("Transaction receipt:", receipt)
else:
print(f"Unknown action: {action}")
sys.exit(1)
```
## Results
From the result image above, you can see that when we initially ran the get command, we got the expected `Current greeting: Hello, World`.
Then, when we go on to run the set command with the string set to "Good Morning Everyone!", we do get the same expected result when we run the get command; `Current greeting: Good Morning Everyone!`

1,862,861 | 3 Reasons You’re Not Closing Deals Like a Pro | You’ve been working hard, putting out content, building your brand, and finally, it happens. A... | 0 | 2024-05-23T13:08:29 | https://dev.to/devdiscove19083/3-reasons-youre-not-closing-deals-like-a-pro-1f0n | sales, career | You’ve been working hard, putting out content, building your brand, and finally, it happens. A prospect who has been following your posts for some time finally reaches out, expressing interest in your product or service. This is the moment you’ve been waiting for, right? The moment when all your efforts pay off.
Excitedly, you do what any eager entrepreneur would do: you immediately send them your prices, list all the features of your product, and even include your payment details.
And then… nothing. The prospect reads your message but never responds. EVER AGAIN.
You’re left scratching your head, wondering what went wrong. How could you lose the sale when they seemed so interested?
Let me tell you exactly what happened.
## 1. You Skipped the Rapport-Building Phase
Here’s the truth: sales aren’t just about transactions; they’re about relationships. When a prospect reaches out to you, it’s crucial to build rapport and establish a connection first. Diving straight into prices and features might seem efficient, but it often backfires.
Think about it this way: would you propose marriage on the first date? No, because that would be rushing things and not taking the time to build a genuine connection. The same principle applies to sales. When you focus solely on the transaction, you miss out on the opportunity to understand your prospect’s needs, desires, and pain points.
Instead of immediately sending prices, steer the conversation toward understanding their situation. Ask questions like:
What motivated you to reach out to me?
What challenges are you currently facing?
How have you tried to address these challenges in the past?
These questions show that you care about their specific needs and that you’re not just looking to make a quick sale. Building rapport isn’t just about being friendly; it’s about showing genuine interest in your prospect’s problems and demonstrating that you have the expertise to solve them.
## 2. You Failed to Position Yourself as an Advisor
As an entrepreneur, you’re not just selling a product or service; you’re selling your expertise. When a prospect reaches out to you, they’re looking for guidance, not just a price list. They want to know that you understand their unique situation and that you can offer a solution tailored to their needs.
Imagine going to a doctor with a health concern, and instead of examining you and asking questions, the doctor just hands you a list of medications. Would you trust that doctor? Probably not. You’d want the doctor to diagnose your issue and recommend the best course of action based on their expertise.
The same applies to sales. When prospects reach out, don’t just present them with options. Instead, dig deeper into their pain points and offer tailored solutions. Position yourself as their trusted advisor, not just a salesperson.
Here’s how you can do this:
Understand their problem: Ask detailed questions to get a clear picture of their situation.
Provide insights: Share your expertise and offer insights that demonstrate your understanding of their industry and challenges.
Recommend a solution: Based on your understanding, recommend the best course of action. Don’t just give them choices; give them your expert opinion.
When you position yourself as an advisor, prospects will see you as an expert they can trust, and they’ll be more likely to follow your recommendations.
## 3. You Focused on the Transaction, Not the Relationship
One of the biggest mistakes you can make in sales is focusing too much on the transaction and not enough on the relationship. Sending your prices too early in the conversation can signal to the prospect that you’re only interested in the money, not in helping them solve their problems.
Think about it from the prospect’s perspective. If you don’t take the time to understand their needs and provide value before discussing prices, they might think you’re just in it for the sale. This can make them hesitant to move forward.
Instead, focus on building a relationship and providing value upfront. Here’s how:
Delay the price discussion: Move the conversation away from prices and toward understanding their needs. Provide value first by offering insights and advice.
Showcase your expertise: Share case studies, testimonials, and success stories that demonstrate your ability to solve similar problems.
Provide a consultation: Offer a free consultation or strategy session to help them see the value you can provide before discussing prices.
By focusing on the relationship and providing value upfront, you build trust and demonstrate that you’re genuinely interested in helping them succeed.
## Conclusion: Slow Down to Speed Up
In the fast-paced world of sales, it’s easy to get caught up in the excitement of closing a deal. But remember, sales aren’t just about transactions; they’re about relationships. When you take the time to build rapport, position yourself as an advisor, and focus on the relationship rather than the transaction, you’ll close more deals and build long-term, loyal clients.
So, the next time a prospect reaches out to you, slow down. Take the time to understand their needs, provide value, and build a relationship. Don’t rush the process.
If you need help and clarity on improving your sales approach, don’t hesitate to reach out. I’m here to help you succeed.
