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 🥁

Userlist’s founders had a $1k onboarding fee in mind. My cohost Mariya Delano: “No, no, it needs to hurt.” She knows a one-person business that spent $20k on consulting fees alone. Smart Bear Live E11:

I want to trade my kids to kids who do give a damn about winter time 🤣

Holy moly, if you use Railway, rotate all your API keys/credentials asap. Especially your database credentials. All environment variables exposed! blog.railway.com/p/security-d...

If I had retainer jobs for apps I would increase my rate with at least 50%. Now is the perfect time, the PHP incidents was the biggest news at the largest Dutch news site yesterday. AI can reverse engineer security incidents faster than ever. You have to stop what you are doing and react asap.

Saw the docu 'The Plastic Detox' yesterday and holy fuck. Ordered a steel Aeropress just now. Not going to add hot water into plastic twice a day anymore 😂

As a giant nerd who dislikes doing marketing I have to make it fun for me to be able to fully focus on it. These tiny details makes it fun for me. Just updated a blog post with data straight from production via Nusii's admin MCP.

Just wrote the prompt of a new hobby project! Something about finding 10k runs around where I live. Will share more when I made the decision of the domain (and actually bought it 😅)

I saw 'La bola negra' in the cinema yesterday and I can't recommend it enough. It is based on a true story during Spain's civil war, with an angle that is never really talked about. An absolute master piece! www.imdb.com/title/tt3551...

A group of top-tier Rails developers I know and worked with (plus myself) were unfortunately laid off today. Any company would be fortunate to pick them up. If you or anyone you know is hiring, send me a DM 🙏

Redoing my alternative pages so doing some research on competitor. Just found out that my biggest competitor simply doesn't believe in refunds 😅

It deserved a stand alone page! nusii.com/wall-of-fame/

Total 26 new testimonials!

Tip for the linkedin game, put an emoji as first name. It is even more obvious that bots are talking to you 🧑‍🚀

15 text testimonials, 2 video testimonials!

Happy Testimonial Tuesday everybody! First video testimonial in the pocket!

I just told my agent to commit every little change so I can brag more on the socials about how efficient I am.

"Hey Claude, please make the error pages more fun"

Which animated illustration do you like better? nusii.com or nusii.com?hero=overview

Beta testers!

Yesterday I "made" a little game to learn chess coordinates. Please give it a try if you love playing chess but suck at those coordinates! e4e5Nf3.com

The last couple of months, I’ve had trouble sleeping because AI made me more excited to work. Last week, I had enough and solved it with this stupid $5 device 🤣 I sleep from 12 to 8 and simply turn the router off at 11pm. No internet, no more fun! Sometimes simple solutions work best!

Any chess lovers here? I "made" a new app to practise chess coordinates. Check it out! it is free :) e4e5nf3.com

You might live in Cyprus far away from family avoiding paying tax, but can you order a take away paella for €7/person?

I don't write a lot of code by hand anymore, but I still read a lot of it. I'm still very happy that everything is in Ruby 👍

I might be able to buy the most misspelled nusii domain dot com for 2000 euro. Is this worth it? 🤔

This is what switching from one WYSIWYG editor to another looks like. And it aint pretty!

It is normally not advised to give discounts or give stuff away for free but I think it is OK if they give you something back. In this case, a customer's business isn't going very well and they asked to cancel their yearly subscription.

This summer I had a lot of trouble because of spammers signing up with stolen credit cards. Glad all the work paid off, no more spammers anymore! And soon as they managed to come in, they are blocked almost immediately 👌 And next time they try, they need a new ip, working email and credit card.

Besides it is the way non technical connect your app to Claude/ChatGPT, I think MCP's best feature is, that gives a new description every time it reconnects. So you don't have to worry about versioning. Everyone has the newest version all the time, and the agent knows how to use it constantly.
