✅ Coding Mistakes Beginners Should Avoid ❌💻

ssekabira robert sims — Thu, 04 Dec 2025 17:16:20 +0000

1️⃣ Jumping Between Languages

Stick to one language until you're confident. Switching too early slows progress.

2️⃣ Skipping the Basics

Don't rush into frameworks. Understand variables, loops, and functions first.

3️⃣ Only Watching Tutorials

Watching isn’t building. Code along, break things, and fix errors yourself.

4️⃣ Ignoring Problem Solving

Learn DSA from the start. It builds logic, which is key to real-world coding.

5️⃣ Not Using Git/GitHub

Track your code and build a public portfolio from day one.

6️⃣ Copy-Pasting Code

Type code manually. It builds muscle memory and helps you understand how it works.

7️⃣ Avoiding Projects

Even small projects teach more than theory. Build something after every concept.

8️⃣ Not Asking for Help

Use Stack Overflow, Reddit, or Discord. Community support accelerates learning.

9️⃣ Burning Out

Take breaks. Stay consistent rather than trying to learn everything in a week.

Project Updates

Yeah Yeah Yeah, tdy am just gonna share a glimpse of my project's code 😊, it might be so slightly not understandable but good enough i wrote this code with other two guys, GOD and AI but at some extents these guys seem to know much and am left behind with no ideas. JOKING, 😄 , I know everything. But hopefully i have been able to reach a milestone on this mvp and am truly making progress now and things are moving up smoothly. Soon will be dropping more if u understand the code.

Let's continue building

✅ Authentication & Authorization Basics 🔐🌐

ssekabira robert sims — Tue, 25 Nov 2025 21:04:20 +0000

🔹 What is Authentication?

It’s the process of verifying who a user is.

🔹 What is Authorization?

It’s the process of verifying what a user is allowed to do after logging in.

✅ Step 1: Authentication – Common Methods

• Username & Password – Basic login

• OAuth – Login via Google, GitHub, etc.

• JWT (JSON Web Token) – Popular for token-based auth

• Session-Based – Stores session on server with session ID

✅ Step 2: How Login Works (JWT Example)

User sends email & password to server
Server verifies and sends back a JWT
JWT is stored in browser (usually localStorage)
On each request, client sends JWT in headers
Server checks token before giving access

✅ Step 3: Authorization Types

• Role-Based Access – Admin, Editor, User

• Resource-Based – Only owners can edit their content

• Route Protection – Block some pages unless logged in

✅ Step 4: Protecting Routes (Frontend Example)

if (!localStorage.getItem('token')) {
  window.location.href = '/login';
}

✅ Step 5: Backend Route Protection (Express.js)

function authMiddleware(req, res, next) {
  const token = req.headers.authorization;
if (!token) return res.status(401).send('Access Denied');
  // Verify token and decode user info
  next();
}

✅ Step 6: Common Tools & Libraries

• bcrypt – Hash passwords

• jsonwebtoken (JWT) – Create & verify tokens

• passport.js – Auth middleware

• OAuth Providers – Google, Facebook, GitHub

✅ Step 7: Best Practices

• Always hash passwords (never store plain text)

• Use HTTPS

• Set token expiry (e.g. 15 mins)

• Refresh tokens securely

• Don't expose sensitive data in JWT

Ehhhhhhhhh, things are easy especially writing electron in typescript 😢 but worth the pain coz learning through building is also another level of leveling up ☝️. I am using ai to help me out to debug and write some pieces of code while being inquisitive about every line it helps to write or fix 🧰 of code, i am so thankful that i started sharing my journey for this link management system with all of u👍.

Soon will be releasing v1.0.0 on github release and will drop link to setup files for the windows version...!
