The Halloween @github.com contribution view is pretty neat :D
The github contribution tiling view, with Halloween colors. Yellow to brown scale, yellow is less activity and brown is more.

YouTube decided to display my leaked passwords as the thumbnail for a … 2h49 video 😱

If you want to learn about authorization, roles and permissions in Spring Security, and optionally steal my very secure passwords, check out my deep dive from @devoxx.com !

Aaron Parecki on OAuth2 (for MCP servers).

Perfection 😙👌

Source: youtu.be/mYKMwZcGynw?...
Diagram summarizing modern OAuth 2.0 best practices. The RFC6749 OAuth Core shows four flows: Authorization Code, Implicit (crossed out), Password (crossed out), and Client Credentials. Annotations recommend PKCE and newer RFCs: RFC7636 (PKCE for confidential clients), RFC8252 (PKCE for mobile), and best practices for browser apps. A red “Security BCP” banner advises against deprecated flows. Under RFC6750 Bearer Tokens, three token transmission methods are listed: HTTP Header, POST Body, and Query String (crossed out).

#springio25 is a wrap 🎬
I had hell of a great time, amazing crowd, great discussions with experts, delicious food and good times with friends in lovely Barcelona.

Soon the videos, to watch everything I missed 🤓

Thanks for putting it together @sergialmar.com . You are a pillar of this community 💚
