I've written dozens of landing pages for my own products over the past decade.
Spent thousands on ads. Hired the coaches. Followed all the frameworks.
Most still converted at 2%.
Then I realized something that completely changed how I think about landing pages.
The problem wasn't the copy, the design, or the offer.
The entire model was backwards.
I explain what I mean here:

Rails is still the best tool for building an online business.
The more I use JS (React, TS, etc.) the more I realize that.

The funny thing about AI is realizing how easy it is to mimic our (so-called) intelligence.
Are we really that smart? Or are we just good at pattern recognition?

The hard thing about talking to people is realizing that everyone thinks he's right, even though that's rarely the case.
The second hardest is realizing you might not be right either.

I send most of my support questions on the weekend. That's when I have time to shop.
And if a company answers, on the weekend, they've got me as a client. That's how impressed I am.
AI makes support run on autopilot. Support agents can automate that for tou.

The #1 lesson I've learned about running a business is lead generation keeps the lights on.
I made an AI generator that's helps me brainstorm lead magnet ideas.
Link in profile if you want it.

Stumbled upon a frustrating issue with iframes today so I though I'd share the fix.

Value is subjective, so it's almost impossible to come up with good product ideas unless you're building products for yourself.
The alternative is to talk to people. Which is also the hardest.

The problem with MVPs (minimum viable products) is people tend to underestimate what the table stakes are.
Making useful stuff is about helping people, not about features and buzzwords.

There's no better feeling than making something yourself, no matter how small.

If you're thinking about how much 💰 you'll save switching from something like Heroku to Kamal, think again.
Lost a whole day with stupid errors that lack documentation.

More Rubyists need to look at the Async gem, Falcon web server, and ecosystem.
If enough people use it, our ecosystem will start having capabilities that we envy when we look at Phoenix LiveView.
Maybe streaming AI API's is the path to this becoming a bigger deal?

"Ruby can't do concurrency well"? 🤨
Tell that to RubyLLM running parallel AI calls with proper streaming using Async:
Async {
3.times {
Async { RubyLLM.chat.ask("...") {|c| puts c} }
}
}
w/o changes to the library. Guide soon at rubyllm.com

You can't run a business without leads.
3 questions to get you started:
1. Does your product solve a painful problem?
2. Are you reaching your ideal buyer?
3. Is your product the best option for them?
If you answered "yes" to all, you're on the right track.

The best thing you can do if you're looking for business ideas is to turn your ad blocker off.

Introducing Honyaku! This Ruby gem automatically translates your Rails application into new languages using OpenAI. It supports rules files for tuning translations and intelligently skips files that don't need a new or updated translation. 🌎

Nothing can beat Hotwire! 😉
When I hover over a sort link, the browser pre-fetch and caches the request. Subsequent clicks will use the cached version until a new record is inserted in the database. This is absurd!! 🤪
