someone built a web-based System Design Simulator.
you drag and drop components (api gateways, dbs, caches) and it actually simulates real-time traffic.
you can watch latency, bottlenecks, and failures happen live...

Honestly, I love PDFs.
But I HATE uploading them to someone else’s server.
So I built pdf0.dev 👇
• your PDFs never leave your browser
• merge, split, compress, watermark PDFs - all client-side
• no signups required
• 100% free & open source
The best part?
- I vibe coded this in a single prompt using @blackboxai. It took me longer to purchase the domain than it took Blackbox AI to build this thing 💀.

How do you create HttpClients in .NET?
The recommended approach is to use the IHttpClientFactory.
Your first option is to use the IHttpClientFactory directly.
The downside is you'll have to configure the HttpClient every time.
If you want to get a pre-configured HttpClient, you have two options:
- Named clients
- Typed clients
Here's the right way to work with HttpClient in .NET: milanjovanovic.tech/blog/the…
I prefer typed clients, because I can hide the implementation details.
But as far as HttpClient setup goes, named and typed clients are equal.

What does your CI pipeline look like?
Here's a simple GitHub Action for building and testing your .NET application.
This is an easy way to get instant feedback when something breaks in your application (assuming you have tests in place).
You can steal the source code for the CI pipeline from my article.
Check it out here: milanjovanovic.tech/blog/how…
This is a good baseline for most projects.
You can easily extend it with more functionality if you need to.

How can you find the Tenant ID in multitenant applications?
You have at least 3 options:
- Request header
- Cookie
- JWT
The Tenant ID comes from the HTTP request header in this code snippet.
A few other options to get the TenantId are passing it in the query string or fetching it from an identity claim.
Using claims will probably be the most secure approach.
You can even fetch the tenant ID from the database (at the cost of performance).
Then, you can use EF Core to implement Tenant filtering.
Here's how: milanjovanovic.tech/blog/mul…
How about async processing?
Background jobs = use job data
Messaging = add to message payload
