5/ Key takeaway:
Caching = performance booster ✅ but comes with responsibility ⚠️.
Use it wisely and always think what, when, and how to cache.

1/ Ever wondered why apps sometimes feel so fast? That’s often caching at work. Let’s break it down in a few tweets. 🧵

4/ Tradeoffs to consider:

Cached data can be stale → must handle expiration

Memory/storage costs

Complexity in cache invalidation

Not all data is worth caching

14/ If you're learning backend or system design:

Understand both.

Most real systems today actually use
REST + GraphQL together.

REST vs GraphQL — The Only Thread You Need 🧵

1/ If you build APIs, you’ve heard this debate: REST vs GraphQL.
Both solve the same problem: letting clients talk to servers.
But they do it very differently.
Let’s break it down in the most practical way possible.

13/ Final takeaway:

REST is simple and stable.
GraphQL is flexible and powerful.
The best teams pick the right tool for the problem, not the trend.

Without HTTPS:

• Passwords could be intercepted
• Payment info could be stolen
• Data could be altered in transit
HTTPS is the foundation of backend security.
Every secure system starts here.

What is HTTPS and why does every website use it? 🔐

When you open a website, your browser talks to a server.
That communication needs to be secure — especially for passwords, payments, and personal data.
That’s where HTTPS comes in 👇

[Trying IT @Trying__IT]

HTTPS = HyperText Transfer Protocol Secure

It does 3 main things:

1️⃣ Encrypts data (so hackers can’t read it)
2️⃣ Verifies the server (so you know it’s legit)
3️⃣ Protects data integrity (so it isn’t modified in transit)
It uses SSL/TLS encryption to make this happen 🔒
