🚀 NEW SKILLCEF VIDEO — LLMs Explained From Zero | Part 2

Ever wondered how ChatGPT actually reads your question?

In Part 2, we go inside the first step of an LLM:

TEXT → TOKENS → TOKEN IDs → LLM

You'll learn:

🔹 What AI tokens actually are
🔹 Why 1 word ≠ 1 token
🔹 What a tokenizer does
🔹 Token IDs explained simply
🔹 Context & context windows
🔹 Input vs output tokens
🔹 Why tokens affect AI costs
🔹 Real Python code using a Mistral tokenizer

This is the beginning of the journey toward understanding and eventually building with open-source/open-weight LLMs like Mistral. 🤖

Ever wondered how a link shortener like Bitly handles billions of redirects without slowing down? 🔗

It is one of the most common system design interview questions, so we made a 3-minute video that walks through it step by step:

✅ How a short link is created and redirected
✅ The database design, and why the short code needs a unique index
✅ Caching with Redis so popular links never hit the database
✅ Sharding, multi-region servers and fault tolerance

If you are preparing for a software engineering interview, this is a good one to watch and save. 📌

Hi everyone! 👋

We're running an interesting experiment at **Skillcef**.

We believe the education ecosystem has become really good at **teaching**, but not so good at **measuring what people already know**.

Before we build further, we want to validate this hypothesis with real users.

So we're launching an **invite-only Founding Cohort** for a limited number of students and working professionals who are passionate about career growth and willing to share honest feedback.

As a Founding Cohort member, you'll get:
✅ Early access to Skillcef
✅ Personalized skill assessments & insights
✅ The opportunity to shape the product through your feedback
✅ A Founding Cohort badge on your profile

If you'd like to be considered, sign up at:
🌐 https://portal.skillcef.com

👉 Choose **"Learner"** during signup.

We'll personally review all applications before inviting members to the cohort.

If you know someone who'd love to be part of building the future of career intelligence, feel free to share this with them. 🚀

🚀 Deep Space Isn’t Just Empty… It’s Deadly.

What happens when humans leave Earth’s protection and step into deep space? 🌌

In this video, I break down the real danger of space radiation — one of the biggest challenges astronauts will face during the Artemis II mission.

👉 Watch here: https://youtu.be/aCkESbKBGYk

💡 Beyond Earth’s magnetic shield, astronauts are exposed to:

☢️ Galactic Cosmic Rays
☀️ Solar Particle Events
⚡ High-energy radiation that can damage DNA

⚠️ Missions like Artemis II will take humans far beyond low Earth orbit, where radiation levels are significantly higher and harder to shield against

This isn’t sci-fi — it’s the biggest biological challenge for future Moon & Mars missions.

👨‍🚀 The question is:
Would you take the risk?

What really happens to the human body in deep space? 🌌In this video, we break down the science of deep space radiation, one of the biggest threats astronaut...
