Introducing the game I am vibecoding for #vibejam by @levelsio

ECHO-9: futuristic noodles delivery 🍜

Gameplay in 2 devices simultaneously :
- Desktop to control player
- Phone for balancing noodles on your head and look at the map (and more)

Still WIP but couldn't wait to share already with you. Have fun!

Feedback and tips are welcome.

Everyone saying “just rotate your keys” about the Vercel breach is missing it.

If this touches npm / Next.js, it’s a supply chain risk.

One bad release upstream
→ thousands of apps pull it
→ you’re compromised by default

We’ve identified a security incident that involved unauthorized access to certain internal Vercel systems, impacting a limited subset of customers. Please see our security bulletin:

Saw it happening live from the idea to the execution !! Congrats @tonnoz

Here's how I made $20,000 in 10 days

With an app that makes your MacBook moan when you slap it🖥️👋 💨
Yes, really. 2026 is so unhinged.
Your idea might be next, go ship that silly project 🚀

[Tonino Catapano (tonnoz) @tonnoz]

@ProductHunt just gave Product of the Day 🥇 to my silly vibecoded app I made for fun.

Moreover, today marks exactly 10 days since SlapMac went live, which made me $20,700 in gross revenue.
I'm still gasping at the screen 🫠

Many may think it's another absurd and lucky overnight success, but while it might seem that way, it wasn't. Let me explain.

My story:
Back in 2018 I was just a backend corp. guy who stumbled on @levelsio and his book MAKE, and something genuinely broke open in my brain.

I wanted that life so badly that I went full obsessive: every @starter_story video, every @marclou marketing technique dissected and noted. Tweets from @tdinh_me were my inspo too.

I started doing my small experiments (like @FpvBuddy): my playground to learn frontend, BaaS and the world of indie such as requesting payments, marketing & SEO.

Then I started meeting people in the space: builders in Southeast Asia, then in Amsterdam. The kind of delusional, hungry optimists who bet everything on themselves. Those conversations changed how I think about making money online.

Recently I even got my whole X profile roasted by @robj3d3, which was equal parts painful and clarifying haha, thanks dude. @transitive_bs also said something that stuck with me around that time: "what is blocking you from doing this full time. How can we make that happen?"

I was about to give out with content making and tweeting when I met @did0f and his way of teaching tech through video format truly inspired me to keep going.

And so, a few months later I made a video for fun, reviewing a repo that makes your laptop moan when you slap it, and things moved pretty damn quickly from there. 24 hours of hacking with the Hackadam crew later, there was a real app, written from scratch at the speed of light thanks to AI.

Is SlapMac a business? No. But it's the kick that starts one. I'm done accumulating knowledge and ready to build for real this time.

Overnight success is very often a lie.
Mine took 6 years of learnings and a single slap 👋💨

8 months after soft launching my little app RouteSketcher, it has reached:

- 1800+ users registered
- 720+ sketches saved
- 1000+ AI generated sketches generated
and a few bucks in revenue as well 💰!

all of this dedicating only some of my free time and doing only organic (micro)-influencer marketing collaborations.

Plans for 2026:
- find ✨pmf✨
- launch on PH, HN, Reddit
- various migrations & tech. improvements

Good end of the year everyone 🥂

A reminder for myself and for everyone in the same situation

[Iron @IronBrands16]

✍️ I wrote a note to everyone waiting for the right idea

It’s not really advice. More like a reflection. Also no rocketship stories.

Six years ago, I started my first startup during my final year of university.
Struggled a lot. Did some stupid shit.

Today I run two profitable, bootstrapped companies and a third’s in the making.

I just stayed in the game long enough to kinda figure it out.

If you’ve been thinking about starting something but haven’t moved yet, this one is for you → https://t.co/iOSKHjDkJG

@IronBrands16 Hi Iron, I’m in Amsterdam and I would like to join, is there still space?

Elon Musk just stole 18 of Mark Zuckerberg's best AI engineers.

Zuckerberg offered his engineers $250 million each to stay at Meta.

But Elon gave them something money couldn't buy, and they abandoned Meta immediately.

Here's the offer that Zuck's own team couldn't resist:
