> ceo fired then coup's his way back into the company

Are we discussing Steve Jobs in 1985?

Any time there is that much money and power involved there is going to be intense drama.

I do the same and I'm having the most incredible success.

Here is an example of the skills I define. [0] It will copy the repository into a /tmp/ folder, load all the dependencies, change all the code at the important places injecting debug statements that print to file with timestamps and meta data, and even if the code works it will still analyze the output. It will also use a snapshot test utility which is several times less expensive after performance tuning than any MCP or browser use service, drive user journeys looking for any place it isn't pixel perfect. (hmmm I didn't fold the snapshot util into that project because the project is a testing tool to begin with). Here is the snapshot utility. [1] With any front end code it will run it in Playwright using Chrome DevTools Protocol to do performance testing. [2]

It does this in iterations with little friction and my sh*t is flawless! Moreover, Fable offer no benefit over Opus with this approach. Plus, the red-team and especially any adversary testing utility or skill will trigger Fable.

You are smart!

Another YC startup went this path, scraping targeting endpoints, and they didn't get much traction and they have since pivoted.

> We maintain a caching layer and avoid hammering websites.

This made me think of it. It is another way to avoid hammering websites by using extremely targeted requests for the most part bypassing HTML, DOM, and JavaScript.

Have a look at Intercept. [0] I don't have a need for it, likely it is dated and will require some more tuning, and I want to get away from scraping. Creating typed Typescript proxy API for any website might be something you find useful.

> Reverse-engineers any website by doing a breadth search across every transport (JSON, WebSocket, WebRTC, GraphQL, SSE, HLS, PubSub), listing them all, and generating a typed JSON API that bypasses almost all bot protections — including Turnstile. I didn't include the ability, but it bypassed the most advanced ChatGPT + Turnstile. Built with self-improving Claude Code agents that rewrite their own instructions until fresh agents consistently succeed.

> Once connected to a page, it intercepts every byte of network traffic — then actively drives the page to surface endpoints that only fire on interaction. It types into forms, clicks buttons, scrolls, triggers modals, paginates, submits searches, and walks through multi-step flows, watching what each action produces on the wire. Every request gets captured with its method, headers, payload shape, and response, then classified by transport (JSON, WebSocket, WebRTC, GraphQL, SSE, HLS, PubSub). The result is a complete map of the site's real API surface — including the hidden endpoints that only exist behind a click — turned into typed proxy routes you can curl.

Another way to look at it; I'll be long gone when a child born today will be paying it. Why do you think I'm concerned about a child who I will never meet getting stuck with debt I voted to accrue?

Probably is an issue but sea turtles hearing is adapted to ocean not air and low frequencies. Also, waves and wind blowing likely muffle a lot of noise.

The organizations that do this have mobile apps and collect tons of data. If I'm use ML, I'd start with time series forecasting to see if I can get the window done to a few hours.

It was the initial culture / behavioral interview for a job developing AI for education of children. Considering how these drones are used in the article linked, the question is apropos.

There are ~350,000,000 of us. When I read we spent $1B, I think about how I'm responsible for $3 of that. It doesn't matter considering the ~$117,550 of the national debt I'm responsible for. It palls compared to the $3,000 a year in interest towards the national debt I'm responsible for.

What boggles my mind is that I make coffee at home because I'm frugal. I guess it is good the government and DoD are seeking cheaper alternatives also.

My favorite interview question: If I gave you a swarm of autonomous drones, what would you do with them?

There is a group in South Florida who stand watch over turtle nests on the beach to ensure the hatchlings make it to the ocean instead of instinctively moving towards the street lamps or the bright hotels. I would use drones to hover over the nests to detect if the turtles hatch so people don't have to stand there.

What would you do?

Thank you for the thoughtful reply.

I would make the argument that people would have to weigh the cost of being accessible to the last 2% vs the cost of losing the last 2%.

Anyone who delivers mail to rural farmers 100 years ago would lose money. There are 3 options. 1. If farmers want mail, they can pay the extra costs. 2. Force, by law, mail carriers to deliver at a loss to farmers. 3. Rural Free Delivery, the government taxes everyone and pays for the free delivery to farmers.

Although almost all farmers in the United States and a majority of users on Hacker News would disagree with me, the answer is the government should continue to deliver free mail to rural farmers. The collective benefit outweighs the cost.

Former chef here (2 Michelin starred restaurants).

5% is beyond plenty; it is awesome!

> works for 98% of the population, that means that it won’t work for ~150 million people

If I can only cook for 70 people a night, I most likely can't serve the ~150 million people who do not have access to modern browsers. And, those who do have access to those browsers and choose not use those browsers likely will not enjoy my food either. I don't need to make 8 billion people happy for my restaurant to survive. I only need to make ~1000 people happy who keep returning for anniversaries, birthdays, and the pure enjoyment of creativity with food.

I was a yacht chef for years and only needed to make 10 people happy. The technique I used was everyone eats the same thing, crew and guests. Saving money doing my own shopping instead of relying on provisioning companies that would send me food not handled correctly, my monthly expense went from ~$30k to ~$10k when guests are on board a month -- food in St. Barts was flown in from France everyday and expensive, circa 2005, so I could afford to serve the chateaubriand, osso bucco, and everything else to the crew. Therefore, what I wanted to eat everyday which likely was balanced, had lots of fiber, and healthier choices was the thing that everyone ate everyday.

People ask if the guests and owners would tell me what they want to eat everyday. The Mister was CEO of a fortune 500 company and when retired still chairman of the board. This guy was making billion dollar decisions everyday and the Mrs. was very busy also. The last thing they want to do is answer what is for dinner every night. They delegated the decision making to me. I always cooked what I wanted to eat and was always correct.

It is impossible to make everyone happy. Don't try -- it will break you.

For one year I reverse-engineered the major education platforms — Google Docs, Microsoft Office, Nearpod, Kahoot, ect. — so that AI agents can drive them on a teacher's behalf and automate classroom workflows. The work runs in over 10,000 classrooms today.

Building agents against production code you don't control is harder than it sounds. The code is mangled, so first you have to understand how the app was built and then take it apart from the outside. It's reverse engineering, but it depends on knowing how to build the thing in the first place.

The role came with monthly compliance and security training centered on FERPA, so I'm fluent in handling student data responsibly. That's not new ground for me. I spent five years building on Drupal, which the most prestigious learning institutions still run today, and version control and access control were the hard part of every project. Student data is the same problem.

I've been building browser agents and browser automation since 2018, well before it was a category. That's paired with 13 years of building dynamic, data-heavy UIs for web and mobile.

I've also built admin dashboards for a custom legal document management system. And a CRM for email marketing, with a drag-and-drop interface for designing and branding email templates for social campaigns. I've taken several companies from 0 to 1, as a consultant and as a full-time employee, across fintech, streaming, real estate, education, marketing, and media. I've worked at a 130-person AI company and on a 7-person team where I wore every hat. I do my best work on small, fast-moving teams.

So was Rural Free Delivery. Farmers being able to communicate was a massive boon. There is a channel for farmers called RFD tv. They completely scrubbed the free provided by the government part after private equity bought the tv channel targeting farmers. Then they got Imus in the Morning so farmers listed to Imus, Rush, Hannity, and orielly forgetting the government helps them.

There is a lot of copying that isn't protected by copyright. It is possible to include what can't be copied that might not fall under copyright in the terms of service contract. Many people not being able to use copyright to prevent copying instead successfully sued based on breach of contract.

Companies should understand that they can protect their IP this way.

Did you agree to terms of use? Did you have to click a check box that you agree to terms of use before seeing or having access to the items you copied? Click wrap. If in the contract that you agreed to there is language that you agreed to not copy the work, then you likely are in breach of contract. If it is publicly available knowledge probably not breach of contract. I’m not a lawyer of course.
