@ragman I mostly model in SysML v1, but it overlaps a lot with UML. So I start with PlantUML a lot when prototyping or for an everything-as-code approach.

SysML v2 has textual representation, though it reads a bit more like code then a markup language like PlantUML.

The INK notebook now has its own experimental AR web app!
- Much simpler than Da Vinci Eye
- No app installation needed
- Works on both Android & iPhone
Just open in Chrome and start tracing.

OAuth 2.0 and OIDC Explained with UML
A blog by Ronald

The purpose of Open Authorization 2.0 (OAuth 2.0) is to give an application (the "Client") limited access to your data at another service (the "Resource Server"), without having to give your password to that application. When OIDC is added Single Sign-On (SSO) is supported as well. The flow...

does anybody know any free #uml class diagram makers that don't require me to sign up and also don't use "ai"

Any tool recommendations for creating UML diagrams/adjacent. For systems/processes?

Sequence, flow, state machine, use case etc.

Whenever I search it’s either vendor locked subscription SaaS or some basic but usable tool that costs $800 for a license, Im happy to pay non-enterprise level amount for a good tool.
(I know there’s a having cake and eating it too argument here)

But wondered what options am I missing?

„I deleted my source code“

„The classic development workflow we all know and loved, is disappearing fast. We will no longer care about the nitty gritty details of how the code works. We will only care that it does.“

Experiment in #php that has unit tests, some spec markdown files plus skill files to fill the src folder on every push according to specs/tests.

Old heads cry in #UML, model driven development and flow based whatever. Can't remember all the hyped methodologies. Thought visual driven development. Typed that into Google and found "visual reverse engineering" that uses legacy UIs to guess what a system does and recreates it in "not #COBOL" or "not #Delphi"!?

Lots of "The Purpose of a System is What it Does" systems out there nowadays, I guess. What do old cyberneticists make of all of this? #posiwid

I deleted my source code

We obsess over clean code because we have to read it. But what happens when we no longer have to?

Ink sketchbooks are my go‑to for #UML design.
I sketch classes, relationships, and structures quickly, no software distractions. Corner markers + page IDs make scans instantly searchable.

@gunstick @elithebearded @lmorchard @thomasfuchs I believe it was Dorian Gray who invented the "timn-sequence diagram" we all use today.
