Javascript Banana

In JavaScript, the code "b" + "a" + +"a" + "a" returns "baNaNa".
Confused?
Let's break it down.

The first two parts of the expression, "b" + "a", simply concatenate the strings 'b' and 'a', resulting in the string 'ba'.

The third part, +"a", is where things get interesting. The plus sign preceding the 'a' is a unary operator that converts the string 'a' into a number. In this case, the string 'a' is coerced into the number NaN (Not a Number).

Finally, the last part of the expression, "a", is simply another string that is concatenated to the previous parts.
When we put it all together, we have "ba" + NaN + "a", which results in the string 'baNaNa'.

This code snippet is a great example of the type of coercion that occurs in JavaScript and how it can sometimes lead to unexpected results. As developers, it's essential to carefully consider the types of variables and expressions in code to avoid these types of surprises.

Debugging is a crucial aspect of software engineering that involves identifying and fixing issues in a software system. Debugging is an iterative process that requires patience, persistence, and a systematic approach. In this post, we will discuss the steps involved in debugging and how to effectively fix issues in software engineering.

1. Reproduce the issue: The first step in debugging is to reproduce the issue. This helps to confirm that the issue is real and to understand the conditions under which it occurs.
2. Gather information: Next, gather as much information as possible about the issue. This may include error messages, log files, and system information.
3. Isolate the problem: Once you have gathered information, try to isolate the problem by breaking down the system into smaller components and testing each component individually. This will help you to identify the root cause of the issue.
4. Test and verify the fix: Once you have identified and fixed the issue, it is important to test the fix thoroughly to ensure that it works as expected and does not cause any other issues.
5. Document the fix: Finally, document the issue and the fix so that other members of your team can understand what was done and why.

Debugging can be a challenging and time-consuming process, but with the right approach and tools, it can be a rewarding and effective way to improve the performance of a software system. By following these steps, you can quickly and effectively identify and fix issues in software engineering.

Dart 101 - What is Programming?
Tags: flutter, dart, mobile, android
Published: 2023-05-04 06:12:05

**Hi there! 😊 In this course, you will learn the fundamentals of the Dart programming language, which is a prerequisite for developing mobile applications with Flutter. You will start with the basics of Dart syntax, data types, and control flow statements, and progress to more advanced topics such as functions, classes, and asynchronous programming.**

**Along the way, you will also learn how to use Dart tools like DartPad and the Dart SDK. By the end of this course, you will have a strong foundation in Dart programming and be well-prepared to move on to developing mobile apps with Flutter.**


Are you curious about what **programming** is and what it involves? Well, you've come to the right place!

**Programming** is the process of creating instructions that a computer can understand and execute. These instructions are written in a specific language that the computer can interpret and follow.


![Person Coding](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bui8ubw81vw3z1zysoyr.png)

In simpler terms, _programming is like writing a recipe_ for a computer to follow. Just as a recipe tells you the steps to take in order to create a delicious dish, programming tells the computer what to do in order to perform a specific task.

Programs can range from simple to complex, depending on what they are designed to do. Some programs are designed to perform basic calculations, while others are capable of controlling complex machinery or performing sophisticated data analysis.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8cpeu86i0bp8iy8x8nmr.png)

To create a program, you need to know a programming language. There are many different programming languages to choose from, such as Dart, Python, C++, and more. Each language has its own syntax (grammar) and set of rules that you need to follow in order to write valid code.

The process of programming involves writing code, testing it to make sure it works as expected, and debugging (finding and fixing errors) if necessary. It requires patience, attention to detail, and a problem-solving mindset.

Programming is a skill that can be used in many different industries, from software development to finance to healthcare. It can also be a rewarding hobby or side project.

So as a conclusion, programming is the process of creating instructions that a computer can understand and execute. It requires knowledge of a programming language and a problem-solving mindset.

In the next article, we will get to know about Dart, Why we use it with Flutter? and What is it's benefits?

I'll see you in the next article! 👨

MangoDB创建项目-> 创建数据库

VS code, 创建Server和client文件夹，cd server -> npm init -y(创建json file 在server文件夹内)

npm install express mongoose cors nodemon 
(express是framework we’re going to use to build our api, mongoose沟通MongoDB和express、node.js的桥梁，cors沟通react and backend)

Server文件夹下创建index.js，这个文件用来存储api

const express = require('express')
用来import express library

const app = express()
设定app 变量用来使用express library

Pidgin 2's Maintenance Mode
Tags: modernization, maintenance, opensource
Published: 2023-05-04 05:00:00

Awhile ago we dropped [Pidgin](https://pidgin.im) 2.x.y to maintenance mode but it appears that quite a few people didn't notice that or aren't quite sure what that means. So today we're going to revisit that and describe what exactly that entails.

When it comes to how software is supported there are a few levels which everyone describes in their own way. For Pidgin we basically use `actively developed`, `maintenance mode`, and `abandoned`.

Actively developed as you might imagine means it is the current focus of the team. This typically means that all new features, bug fixes, and everything else will be worked on. When something is actively developed, releases will be frequest (for some definition of frequent).

As implied earlier, maintenance mode isn't the focus of the team. The team will work on it if a security issue or a pretty bad bug is identified, but otherwise we just kind of let it sit since it is in a working state. However, the majority of the work when something is in maintenance mode actually comes from outside of the core development team.

This work comes from contributors who are generally running into issues and need to get them fixed. The so called "itch scratching" contributors. If they provide a patch to us and it is high quality with minimal side effects we will go ahead and accept it to the a project in maintenance mode. When enough of those stack up, we will do a release.

The important thing to note here though is that they need to have minimal side effects. When something is in maintenance mode, we do not add new API. The entire point of maintenance mode is to keep it running smoothly as best you can. You could almost think of it as a car you've paid of for a couple of years and now you're just trying to keep it running because it's generally cheaper than buying a new car.

Finally, when it comes to abandoned, the best example we have is [Gaim](https://gaim.pidgin.im). Gaim was renamed to Pidgin in 2007 following a trademark dispute. However, we still have the Gaim [source code](https://keep.imfreedom.org/gaim/gaim/) online for historical reasons but we don't anything with it. We will not accept patches and we don't work on it.

Although I did do an April Fools' joke in 2022 where I turned "Pidgin Night" on my [Twitch stream](https://twitch.tv/rw_grim/) to Gaim night as April Fools' fell on a Thursday that year. During that stream, we did manage to get Gaim compiled an running on my machine running [Debian](https://debian.org) unstable at the time.

Hopefully this clears some things up. While Pidgin 2.x.y isn't our focus at all we do want to make sure that users who are using it can continue to use it which is precisely why it's in maintenance mode instead of abandoned.

I hope you're enjoying these posts! Remember they go live for patrons at 9AM CST on Mondays and go public at 12AM CST on Thursdays! If there's something specific you'd like to see me cover here, please comment below!

O que é Selenium e qual sua função na programação?
Published: 2023-05-04 03:26:23

O Selenium é uma ferramenta de automação de testes de software amplamente utilizada na programação. Ele permite que os desenvolvedores automatizem a interação do navegador com uma página da web, simulando o comportamento humano, como clicar botões, preencher formulários, rolar a página, entre outras ações.

Originalmente desenvolvido para ser usado em testes de regressão, o Selenium se tornou uma ferramenta popular para testes de aceitação automatizados, onde os desenvolvedores podem testar a funcionalidade de um site ou aplicativo da web em vários navegadores e plataformas.

O Selenium suporta várias linguagens de programação, incluindo Java, Python, C#, Ruby e JavaScript, o que o torna uma escolha flexível para equipes de desenvolvimento que trabalham em diferentes plataformas.

Existem três principais componentes do Selenium: 
- Selenium WebDriver
- Selenium IDE
- Selenium Grid

**Selenium WebDriver**: 
É o principal componente do Selenium e permite que os desenvolvedores criem scripts de teste usando uma linguagem de programação. Ele interage diretamente com o navegador, permitindo que os desenvolvedores controlem todas as ações do navegador em um nível granular. Isso permite que os desenvolvedores testem sites e aplicativos da web em diferentes navegadores e plataformas.

**Selenium IDE**: 
É uma extensão de navegador que permite gravar e reproduzir testes simples sem a necessidade de codificação. Ele é fácil de usar para testes simples, mas pode não ser tão robusto quanto o WebDriver para testes mais complexos.

**Selenium Grid**: 
Permite que os desenvolvedores executem testes em vários navegadores e plataformas simultaneamente. Isso ajuda a acelerar o tempo de execução dos testes, permitindo que os desenvolvedores testem seus aplicativos em várias configurações de navegador e plataforma em paralelo.

Resumindo, o Selenium é uma ferramenta poderosa para automação de testes de software que permite aos desenvolvedores testar a funcionalidade de um site ou aplicativo da web em diferentes navegadores e plataformas. Ele oferece suporte a várias linguagens de programação e é fácil de integrar aos processos de desenvolvimento existentes. O Selenium ajuda a acelerar o processo de teste, economizando tempo e aumentando a eficiência da equipe de desenvolvimento.

SSR != SSC
Tags: react, nextjs, beginners, webdev
Published: 2023-05-04 02:51:57

SSR (Server side rendering) !== SSC (Server side components)

Server-Side Rendering (SSR) is a technique of rendering web pages on the server before sending them to the client. The server generates HTML content and sends it to the client. The client then loads up all your typical React JavaScript. Server-side components (SSC) are components that are rendered on the server and then sent to the client as HTML.

In summary, SSR is all about the initial page load when you’re using SSR, you are sending HTML to the client and then loading up all your typical React JavaScript. Server-side components (SSC) are components that are rendered on the server and then sent to the client as HTML.
Learning Basic Coding Terminology
Tags: beginners, codenewbie
Published: 2023-05-02 23:46:21

I have been learning a lot during my preparation work from the coding boot camp that I am in. I recognized some of the terms I ran into, such as Hypertext MarkUp Language (HTML), but others - such as Git and GitHub - were new to me. 

However, even though I recognized **HTML** as a term, I still learned new concepts about it. For example, I didn't recognize that it - along with CSS and JavaScript - is a coding language!

I also learned about the **command line** (or the terminal) - a text interface used to run computer programs. I have heard from computer experts that people should not mess with the command line if they don't know what they're doing - they could delete files, crash their computer, or make things completely unworkable. In addition, people should be careful that the commands they type into the command line are spelled correctly and are in the proper case (upper or lower). 

Fun fact: I had to use my computer's command line to be allowed to upgrade to Windows 10. Luckily, there was a thorough walkthrough online that allowed me to be able to do it correctly.

Finally, I learned about Git and GitHub. **Git** is a control system that allows multiple people to work on a project without overwriting each other's work. It also will allow you to go back to previous versions of the project if an error is discovered. **GitHub** basically contains the core functionality of Git in a central repository, as well as providing internet hosting for computer code.

These new terms may take a while for me to grasp fully, but I am committed to learning as much as I can in order to successfully change careers.
