Is Object Orientated Programming (OOP) really as bad as some say it is? Let me take you on a journey from the hype that was, to reality...

People THINK CMake is hard; it's not

And no, this isn't rage-bait. It really isn't anywhere near as hard as some make it out to be.

I wasted a full day building a WhatsApp waitlist system for my SaaS… before realizing I could replace it in just 10 minutes.

I’m building Order Hand — a simple app to help people who sell via WhatsApp or in-person track their sales without messy spreadsheets. My wife is one of them, and this is a real problem for a lot of small sellers.

Sometimes the best solution isn’t the one you build — it’s the one you almost overlooked.

It had plenty of rough edges. But, it worked...
