Hello again!
We are doing introductions?
I'm Dutch living in Madrid, Spain. I have been working on my own startup Nusii (online proposal software) for 10 the last 10 years.
I recently started to do some temporary freelancing on the side just for fun.
I like playing the drums 🥁

Somebody has a decent webcam to recommend for video calls and screencast. Doesn't need to be pro, just slightly better than the standard on a MBP.

About to buy a Mac Studio M4 Max, 64GB RAM 😱
For some unknown reason I prefer a desktop instead of a laptop.
Anybody here regretted buying a Mac Studio?

I'm going to do something I never done before, using you guys as an accountability partner 😅
My SaaS went down the last year and especially this month. I'm going to get it back up again and share here what I'm doing.
I don't like sharing revenue publicly, but I'm going to take current rev as base

Snow Leopard was the best OS ever made. Reason: no new feature, only performance/memory improvements and bug fixes.
Also and OS name you could remember. I cant name you the last 5 versions, even if you point a gun to my head 🤣

So sad, one day after I saw his last video, GM Daniel Naroditsky passed away.
I'm not good at chess but really enjoyed his videos, he made sense of this complex game. It was fascinating hearing him, trully was one of the best teachers out there.
29 years old :(

Another stupid security thing is simply having a random generated url for the admin panel. And a honeypot admin on /admin 😂
So even, if they hack my account, it is still difficult to reach the admin panel.

An overly cautious way to prevent password reset requests on admin users is simply raising an error :)

There is something nice about suffering that makes you complain less.
For example, I never complain about traveling, because once I had a 4-day bus ride, night and day, in South America, all by myself, with no phone.
That was literally the last day I complained about traveling 🤣

For some time I cross posted to X and here. But I naturally stopped doing that. X is more like a slot machine and my posts are never that spicy so they get zero engagement/connection.
I always liked to connect with fewer people but better.
Bluesky is a bit better at that 🤘

Found out that Claude Code is *really good* at guiding me through the Spanish bureaucracy process. It just helped me getting like 10 official documents in like an hour time. Which would take me a Long time before!
It also discovered I had a social security debt in 2023 that I didn’t know off 😱

I had a chat about security and all the ways you can get hacked with my offline none geeky friends last weekend. And I think I scared the shit out of them 🤣
It is concerning how little normal people do to be safe.

Hanging out with the doggy and indirectly with @briancasel.com and @justinjackson.ca after a short run while the kids are away for a few hours.
Hearing about 1000 different things and they all are interested and fueling my motivation for the upcoming week.
Great Sunday so far!

I might become this stereotypical old man screaming, but I’m so happy to have lived my teenage hood without smartphones.
It hurts to see that kids from 4 till 16 sitting together and the only thing they do is looking at those stupid phones.
