We have a Grok of 4.5 in the EU.
Tomorrow there will be tests on real projects.

Wczoraj historia, dziś konkret: RadarM to teraz wtyczka Chrome. Otwierasz ogłoszenie mieszkania, klikasz i widzisz, co warto sprawdzić przed zakupem ��� bez przeklejania czegokolwiek. Darmowy podgląd na start, pełny raport w PDF → https://t.co/aHEbhAcU0c

W marcu kupiliśmy z żoną mieszkanie. Po zakupie wyszły rzeczy, o których nikt nie wspomniał. Dziś startuje RadarM – wtyczka Chrome, która sprawdza mieszkanie prosto z ogłoszenia: cena, księga, sprzedający, ryzyka. Raport PDF zamiast niespodzianek → https://t.co/aHEbhAcU0c

SizzleAir in action: tracking CPU, temperature and thermal pressure on a fanless MacBook Air.

The popover explains why the Mac is heating up. Notifications recommend what to do to get out of throttling.

Yesterday, I did a test launch on Product Hunt with zero pre-existing community. Total clean slate.

Followed the guidelines 1:1 and just shared the link. My takeaways?

Instantly got spammed by paid upvote farms.

Confirmed that the top charts are just a battle of massive pre-built audiences.

The feed is getting flooded with vibe-coded slop apps.

Is Product Hunt completely losing its meaning for real startups today? Does it even make sense to launch there anymore?

SizzleAir is live on Product Hunt.

A tiny macOS thermal assistant for fanless MacBook Airs. It detects thermal pressure, explains likely causes, and suggests one practical next step.

Would love honest feedback from MacBook Air users:

My Codex usage after today's 7-hour workday.

Small update on SizzleAir: I rebuilt the app around a clearer purpose.

It’s no longer about playful heat feedback. It’s now a tiny thermal assistant for fanless MacBook Airs: detect thermal pressure, explain likely causes, and suggest one safe next step.

Why? Because "why is my Air slowing down?" is more useful than another system graph.

If you use a fanless M-series MacBook Air and want to understand when heat affects performance, this is exactly the kind of tiny utility I wanted to have myself.

@robinebers Unfortunately, this offer is not available in Poland. The offer is available for the SuperGrok.

26 years as a dev, designer, and animator... and my own portfolio was always "coming soon."

I finished the design in Figma 3,5 years ago. It sat there gathering dust while I prioritized "fast-paced" client work and the corporate grind.

Now that I’ve pivoted to Solo Product Architect, I finally put myself first and shipped it. It turns out, building your own SaaS gives you the freedom to finally finish your own story. 🚀

To my fellow devs: How many of your personal projects are currently being sacrificed for a client’s deadline?

Do you also have assistants for creating your own digital products?

#IndieHackers #buildinpublic #solofounder

[Mariusz Jankowski @MarJani81]

For the past six months, after 26 years of working a salaried job, I have been developing my own digital products without having any audience. I did not know it would be such damn hard work. But the journey of building 6 products at once is a hell of a ride. 🚀

@tonnoz @tinylaunch Goat sounds are my favorite. They make programming more enjoyable for me every day (:

[Mariusz Jankowski @MarJani81]

Sound on.

This is what MacBook Air thermal pressure sounds like now. Bacon. Boiling water. Popcorn or more.

Very serious laptop science.
