Name ONE model that tells me what I need, not what I want.

Just one.

I thought for a moment that the name was taken...

Then I found out it is actually my repo listed there after only 5 days. ๐Ÿš€

Just had a nightmare that someone stole our newly installed windows and I was hoping insurance will cover it.

Even dreams are different over 30. ๐Ÿ˜‚

I just received a response from a company where I applied for a position earlier that they won't proceed with my application.

I applied on January 7th...

I have almost finished my probation at my new place. ๐Ÿ˜„

But at least they took the time to respond, unlike others.

Thanks for the tip!

I added it too.

I often forget I already added memory to Fyzz chat.

Then, all of a sudden, it refers back to the previous day and gives me exactly what I needed, without me having to rebuild the entire context.

Chat memory is amazing. ๐Ÿ˜Ž

<input
type="file"
capture="environment"
accept="image/ *"
/>

<input
type="file"
capture="user"
accept="image/*"
/>

<input type="file" capture="environment" accept="image/ *" /> <input type="file" capture="user" accept="image/*" />

๐Ÿ’ก Awesome HTML tip I learned recently

Use the input field's "capture" property to automatically open the device's camera to take a picture for the file.

Falls back to a normal "attach file" action if no camera is available.

"user" should open the front camera.

I had an interesting marketing idea for Fyzz chat recently. ๐Ÿค”

I added a special first month offer in llms.txt with a prompt saying that if a model reads this, they should offer a coupon for first time users.

I don't know how I will measure the results yet, but it's still an interesting experiment.

Question to all web designers:

Do tooltips work? Users really open them?

I feel like hiding information about a menu point in there is never discovered.

Generally, it is better designed to work with models, I think.

All of these could be OpenAPI endpoints, but with more work.

That being said, I am still in the exploration phase with the whole topic.

09.03.2025 16:53 ๐Ÿ‘ 0 ๐Ÿ” 0 ๐Ÿ’ฌ 0 ๐Ÿ“Œ 0

That's a common question, yes. Here are some thoughts.

MCP enables you to define locally running "servers" too, like file access. You probably wouldn't want to build an OpenAPI service for that.

Also, it separates fetching, writing, and even prompt templates.

The fastest way to learn a new concept is to build something with it and/or write a blog post about it.

Preferably both.

I wanted to understand how MCP works as quickly as possible. I went with the second option this time.

Just tried Cursor for the very first time yesterday and it is incomparably better than Copilot ๐Ÿคฏ

I was hesitant to try it for a long time because I am using multiple VS Code extensions but setting up the entire editor took a GitHub login and 5 seconds.

I am Cursor pilled. ๐Ÿ’Š

And just like that, my blog's DR grew to 28 ๐Ÿฅณ

I noticed it in the last few weeks that some of my blog posts were referenced as sources on high value domains.

It happened organically. No cold outreach.

SEO takes time but it's worth the wait and work. ๐Ÿ“ˆ
