A Google Developer Expert just published the most detailed guide to becoming an AI engineer I have seen.

Not a pile of lessons, but a separate route for each specialty, and the course walks you through it.

523 lessons across 20 phases, free and MIT licensed. Linear algebra at the bottom, multi-agent swarms at the top, around 342 hours end to end. Code in Python, TypeScript, Rust and Julia.

You never start at lesson one. You pick a destination and it hands you the path:

> New to all of it, phase 0.
> Already know Python, phase 1.
> Want to ship production LLM apps, phase 11.
> Want agents, phase 14.
> Want MCP or Agent Skills, phase 13.

There is a route for using coding agents on real repositories, one for deciding what to build before you build it, and one for Claude certification prep.

Every lesson runs the same shape. You write the algorithm from raw math with no frameworks first, then run the same thing through PyTorch. By the time the library appears you already know what it does.

And each lesson leaves something behind: a prompt, a skill, an agent or an MCP server. One command installs them into Claude, Cursor, Codex or anything reading SKILL.md.

Anthropic engineer:

"You're not supposed to prompt Claude. You're supposed to build a system that prompts itself."

In 45 minutes she shows exactly how Anthropic builds agents that remember, fix their own mistakes and get smarter with every run.

This beats any paid course on agents I've seen.

Watch it, then read the guide on building loops below.

همیشه وسط کار با Claude و Codex به لیمیت می‌خوردم و کل فلوم می‌پرید. این چند روز 9router رو آوردم بالا و کار جمع شد! 9router یه پروکسی لوکال رایگانه که میاد ابزارهای کدت رو وصل می‌کنه به ۴۰+ پرووایدر. نکته‌ی قشنگش fallback سه‌طبقه‌ست: اول ساب خودت، بعد مدل ارزون، بعد رایگان خودشم سوییچ می‌کنه و دیگه با quota exceeded خداحافظی میکنی😎
یه بخش هم داره به اسم RTK که خروجی ابزارهایی مثل git diff رو فشرده می‌کنه اینطوری حدود ۲۰ تا ۴۰ درصد توکنت کمتر مصرف میشه! نکته مهم اینه که اپن‌سورسم هست. اگه چندتا ابزار AI رو هم‌زمان استفاده می‌کنی، حتماً یه تست بکن 👇

In 2016, a man with no CS degree quit his job to study for a Google interview.

He was an English major.
A self-taught web developer.
A former Korean translator in the US military.

He studied 8 to 12 hours a day. For 8 months straight.

Algorithms. Data structures. System design. Operating systems. Networking. Every topic Google asks.

He tracked every minute of it on GitHub. He called the repo "Google Interview University."

Then he applied to Google.

Google never called him back.

Here's the wildest part:

The repo he left behind became one of the most-starred projects on GitHub. Over 343,000 stars. Used by thousands of devs to break into FAANG.

He got hired at Amazon as a Software Engineer.

His name is John Washam. The repo is now called coding-interview-university.

Inside you get:

- A multi-month study plan, week by week
- Every CS topic Google, Amazon, Meta and Microsoft actually ask
- Algorithm patterns with worked examples
- System design from zero to senior
- Big-O, data structures, trees, graphs, recursion, dynamic programming
- Behavioral interview prep
- Mock interview drills
- Book and lecture recommendations he personally used
- Flashcards, video resources, and a coding question practice plan

Self-paced. Free. No course. No paywall. No upsell.

Just one engineer's 8-month study log, open for anyone who wants to follow it.

If you are preparing for a tech interview, this is the most complete free roadmap on the internet.

100% Open Source.

Anthropic pays engineers $750,000+ a year to understand how LLMs work.

Stanford just put a 2 hour lecture that covers 80% of it for FREE.

Bookmark this. Give it 2 hours today.

It might be the highest ROI thing you do this month:

[Deep Psychology @DeepPsycho_HQ]

A HARVARD psychologist says: “if you’ve achieved nothing by 25, you’ve avoided the most destructive illusion of youth”

> In 2021, a Harvard psychologist surprised a lecture hall with an unexpected statement:

“If you haven’t accomplished much by 25, you may have escaped one of youth’s biggest illusions.”

At first, the room laughed.
She wasn’t kidding.

> The illusion of early success.

In your early 20s, the brain seeks quick proof of worth ~status, attention, rapid achievements.

But psychologists warn that chasing recognition too soon can lock people into roles or paths they never consciously chose.

They decide too early… and spend years trying to undo it.

> The exploration phase.

Research on career development suggests that people who explore more before 30 often build stronger long-term directions.

Testing ideas.
Making mistakes in public.
Changing course.

At 25 it looks like confusion ….but by 35 it often turns into clarity.

People who feel “behind” in their mid-20s frequently gain something others miss:

Perspective.
Patience.
And a clearer sense of what truly matters to them.

That foundation often leads to better decisions later on.

At the end of the lecture, the psychologist left the students with one final thought:

“You’re not meant to have life fully figured out at 25.”

“You’re meant to discover who you’re not.”

ژینا گیان قاتلت بە درک واصل شد!

[Imtiaz Mahmood @ImtiazMadmood]

This is the funeral of a young protester who was killed by Islamic Regime last week.

Traditionally in Iran, funerals are marked by sorrow: sad music, Islamic sermons, and recitations from the Quran.

But here, something completely different is happening.
The music being played is the kind normally heard at weddings. People are clapping. They are dancing. At a funeral!

This is not celebration, it is protest.

By rejecting religious rituals and replacing them with wedding music, people are sending a clear and defiant message: how deeply they despise this so-called “religious” government, how strongly they oppose the regime and its imposed ideology.

There is hardly any way more difficult, more profound, or more unmistakable to express opposition to this regime, and yet, the people of Iran continue down this path.

They do not retreat.
They do not back down.
