I decided to approach this differently by leveraging modern AI technologies. I spent time learning the strengths of various LLMs (Grok, DeepSeek, ChatGPT, Claude 3.7) and combined the best aspects of each for my solution.

The technical challenges were substantial. To reach 1B+ verified contacts, I had to:

- Implement residential proxy networks using Luminati/Bright Data, with Node.js for connection management and Redis for IP rotation scheduling

- Develop captcha-bypassing systems combining Puppeteer's browser automation with 2captcha API integration and custom computer vision models using TensorFlow

- Perfect web scraping at scale with Python (Beautiful Soup, Scrapy), optimized with asyncio for concurrent execution, and Playwright for dynamic content rendering

- Build a robust backend infrastructure using Laravel PHP framework, vanilla JavaScript for lightweight frontend interactions, and PostgreSQL for storing the structured data with proper indexing

I hope you enjoy using the trial, I made it especially for you guys.

Input: The website of a company. Any company. Apple.com or Ycombinator.com if you want.

Output: The verified email of every Apple/YC employee we've managed to find. Works for linkedin profiles too — put a linkedin profile in, you get a verified email out.

It's currently cheap as fuck ($10/mo) because it's a hacky piece of software. It doesn't work every time, but it gets improved every 48 hours so it'll be really good soon.

We're also teaching people how to hack sales and advertising, stuff like how to get a 30% response rate with targeted cold email. Basically everyone who's bought a subscription gets a lesson once per week. I've got 10 years of experience teaching skills, so in my opinion it's cool.

Join the discord server here if you want to talk about that: https://discord.gg/2RNwH8ta4A

If you want proof that I can even write an email as good as that: https://imgur.com/a/z9gNgGH

A discord for people who'd like to learn (or improve their) skills by teaching them ^^ No experience needed, we'll teach you how to teach - and if you teach pretty well we'll even let you monetize.

Assuming you're down to try, here's some basic stuff I need:

1) 15-20 minutes for a session zero, where we decide how to teach you. I'll give a plethora of options: e.g., I can be super theory heavy. Or I can emphasize practice with almost no theory. Or you can learn by watching me like a hawk. Or suggest your favorite path.

2) I need a way to get in touch. Discord's great for many many reasons, but if you really don't want to, offer an alternative that can be accessed through a personal computer. We'll need to voice chat as a minimum. Click on my profile for contact info or comment here.

For reasons why this whole thing may not be the best idea, see below:

a) I will ask you to give back in some way (but I'll let you choose how.) You could teach someone (not necessarily me) a skill you already possess. Or you could donate to keep my effort afloat. Or you could choose to decide a bit later. Something like that.

b) I mean to teach you how to teach a skill. This is not the Feynman technique; a skill to me is the ability to reach a specified result automatically and consistently.

c) I live in the Americas; if you're in Africa/Europe you're 6-7 hours ahead. If you're in Asia you're 12-16 hours ahead. (If Antartica, wtf are you doing there?) My schedules tend to be flexible but Asia-located people may struggle to get ahold of me.

If there's any other cons you can think of, leave them here, I'll respond in the comments if I agree.

Here's a simple proof: https://docs.google.com/document/d/13unaqOo02sA4kiBFayoQ01CS...

I shared the technique with a friend, and he doubled his chess skill within 10 hours of training. That is, he went from better than 35% of players to better than 70%.

Here's the thought. I have needed elements for learning a skill, what I call "the fundamentals of meta-learning," and I use them to create new ways to teach. For the next 3 months, I'd like to teach a course around them. They will help you learn skills faster and teach others better.

The course will include theory and practice. The theory consists of necessary conditions for learning a skill, backed with academic evidence. The practice may be students teaching or learning a skill of their choosing, with regular feedback sessions.

Here's a full proposal. Please read it! There's crucial info inside that will help you decide if it's worth it, including a proof of concept and how I plan to finance the project.

Thanks, lmk how it goes.

For instance:

Say I'm camping in the woods, and I want to start a fire. Knowing what's necessary, I look around me: my clothes can be fuel, and my glasses can concentrate the sun's heat. [2]

Do you see what I mean? When I want something to happen, I supply what's necessary. This lets me try new things and quickly learn why they work (or don't.) It's the fastest feedback loop I know.

Now say it's 1833. Humanity's tools for artificial light are candles, gas lamps, and fireplaces. They're expensive, inconsistent, and a fire risk. But if I play with what's necessary, I may notice that fire isn't needed for artificial light, so I place some fuel and heat in a vacuum.[3]

So: When I want something to stop, I suppress a necessary condition. That's a straight way to invent the electric light-bulb (based on nothing nobody's seen) and change civilization forever!

I hope it's clear that needs and causation are almost the same. Necessary is just a way to explain every solution that has worked or is yet to be invented for making or preventing what happens. Thus, it may be useful for learning to code.

So I entreat you, fellow hackers: what are things that happen to coders? I know bugs happen, so bugs have necessary conditions. We could invent a new way to debug. But I bet more things happen in computer science. What, though?

See you in the comments.

*Notes*

[1]: My version is oxidizer, enough fuel for a chain reaction, and heat at the fuel's flash point.

[2]: Oxygen will be in the air, of course.

[3]: The first practical light-bulb was electric current (heat), passing through a carbonized bamboo string (fuel), inside a vacuum tube.
