I’m 21 and planning to start learning System Design now.

Be honest.. am I already late?

[Crypto Jargon @Crypto_Jargon]

THIS IS INSANE. 🤯

India gave GitHub THREE HOURS to delete BitChat.

By the time the deadline hit, the app was already back. On a network with no company to send the order to.

Here's what happened:

• India orders GitHub to remove BitChat, citing "unlawful communication"
• GitHub has 3 hours to comply or face legal action
• Within hours, a developer mirrors the entire codebase on Radicle
• Radicle has no central server. No company. No CEO to subpoena. No app store to pressure.
• The instructions go out: clone it, seed it, keep it alive
• Every person who seeds it becomes another copy the government can't touch

The part nobody's saying out loud: this is the exact scenario BitChat was built for.

It runs on pure Bluetooth. No internet. No SIM. No phone number. It was already unkillable at the app layer, that's why protesters in Nepal, Iran, and Madagascar used it to route around government shutdowns.

Now the SOURCE CODE is unkillable too.

India didn't delete BitChat. It just handed the entire internet a live demo of why decentralized infrastructure exists.

You can order a company to take something down. You can't order a network that isn't owned by anyone.

Command to mirror it yourself is already public. People are seeding it right now.

🚨 Indian government orders GitHub to block Bitchat app in the country.

30 Must Know Terms in Claude
__________

Claude is moving faster than most people can learn it.
So I made a simple 30-term map to catch up in 5 minutes:

1. Models
Opus = deep thinking, strategy, writing
Sonnet = daily work, editing, workflows
Haiku = quick, cheap, lightweight tasks

2. Core Apps
Chat = basic Claude interface
Projects = your workspace for repeat work
Claude Code = for developers and builders

3. Newer Surfaces
Claude Design = build visuals and websites
Claude in Excel = work inside spreadsheets
Claude in Chrome = browse and take action

4. Context & Memory
Projects = task-specific context
Custom Instructions = project-level rules
Memory = remembers useful details across chats

5. Outputs
Artifacts = docs, code, apps, previews
Markdown = Claude's clean output format
CLAUDE.md = instruction file for Claude Code

6. Skills System
Skills = reusable workflows
SKILL.md = instructions behind a skill
Plugins = skills + connectors bundled together

7. Connections
Connectors = Claude linked to your apps
Computer Use = Claude clicks and types
Dispatch = run tasks from mobile to desktop

8. Power Modes
Extended Thinking = better reasoning
Research = deep reports
Web Search = live internet results

9. Smart Helpers
Scheduled Tasks = recurring Claude actions
Global Instructions = default working style
AskUserQuestion = structured input from you

10. Foundations
Prompt = what you ask
Style = how Claude responds
Vibecoding = building by prompting

Most people don't need to learn everything.

But if you understand this map, Claude stops feeling like "just another chatbot" and starts becoming a real work system.

I'm building a full Claude learning library for non-technical professionals.

geçen hafta claude ile 6 saat dijital ayak izimi sildim.

sonuç: 47 data broker listingi kaldırıldı. 12 ölü hesap silindi. 3 arama sonucu bastırıldı.

nasıl yaptım, adım adım. thread.

[Suryakant Chaurasiya @heyitsurya]

AI has its own language.
And nobody taught you how to speak it.

You've nodded through "LLMs," "inference," and "RLHF."
You've googled them at 11pm after a meeting.

That ends today.

Here's what every term you've been pretending to know actually means:

1. LLM (Large Language Model)
The AI brain behind ChatGPT, Claude, Gemini, Copilot.
Trained on billions of documents.
Predicts the most likely next word — at scale.

2. Hallucination
When AI makes stuff up.
Confidently. Completely wrong.
Happens when training data has gaps.

3. Token
The building block of AI communication.
Not a word — a chunk of a word.
More tokens = more cost in enterprise settings.

4. Training vs. Inference
Training = teaching the model.
Inference = the model doing the work.
You can't have the second without the first.

5. Fine-tuning
Taking a general model.
Feeding it specialized data.
Making it smarter at one specific thing.

6. Reinforcement Learning (RLHF)
RLHF = Reinforcement Learning from Human Feedback
AI learns by trial, reward, and repeat.
Like training a dog — but the dog is a neural network.

7. Distillation
Teaching a small model to mimic a large one.
Faster. Cheaper. Nearly as good.
Likely how GPT-4 Turbo was built.

8. RAG
RAG = Retrieval-Augmented Generation.
AI + your own documents.
Reduces hallucinations dramatically.

9. Chain of Thought
Breaking a complex problem into steps.
Like showing your work in math class.
Slower — but far more accurate.

10. Weights
Numbers that shape what the model "knows."
Start random. Adjust during training.
The model's actual learned intelligence — stored as math.

11. Validation Loss
A score that tells you how well training is going.
Lower = better.
Helps catch overfitting before it's too late.

12. Coding Agent
An AI that doesn't just suggest code.
It writes, tests, and debugs — autonomously.
Think: a tireless intern who never loses focus.

The people who understand this language aren't just more informed.

They ask better questions.
They make better decisions.
They sound like they belong in the room.

That's the real edge.

Don't just nod along anymore.

Do this instead:

1. Save this post (you'll come back to it)
2. Pick 3 terms you've been faking — learn those first
3. Share it with someone who pretends to know this stuff

Fluent. Confident. No excuses.
