This is my November Fedi reminder that I am a talented #Java developer looking for a developer position either remote, or based in Tampa, FL. I have some neat skills, like #CoreJava, #JavaEE, #Spring Frameworks, #WebServices, #Kafka, and many others. If you want to set up a call, I promise I will respond. (And I only ask you apply the same rule.)
Oh yeah, something-something-pumpkin-spice; now it's a November post.

Was passiert, wenn dein Shortener IDs vorhersagbar generiert? Hier entsteht ein System, das Base62, ConcurrentHashMap & #Vaadin nutzt, um Risiken zu minimieren – 100 % #Java.
Jetzt Code von @svenruppert entdecken: https://javapro.io/de/teil-ii-url-shortener/
#Java24 #CoreJava #DevSecOps @Vaadin

Lange URLs nerven. Kurze machen angreifbar. Base62, Hashing, Rate-Limits – ein Spagat zwischen Komfort & Missbrauch. Wer sehen will, wie #Java ohne Frameworks digitale Souveränität verteidigt, liest die Story von @svenruppert: https://javapro.io/de/kurze-links-klare-architektur-ein-url-shortener-in-core-java/
-
Ungetrennte REST-Calls zerstören jede saubere Architektur – blockierende Aufrufe, Timeouts, unkontrollierte Fehler. @svenruppert setzt in #Java auf klare Adapter, Typsicherheit & Resilienz.

Wer glaubt, URL-Verkürzung sei nur UX, irrt. Entropie entscheidet über Vertrauen, Kollisionen über Haftung. Ein Shortener ohne Architektur öffnet Tür & Tor für Missbrauch. #Java24 liefert die Werkzeuge. @svenruppert zeigt wie.

Why did #Java survive when Flash & Applets didn’t? The article by Mihaela Gheorghe-Roman lays out how the shift to server-side, modularity & @SpringBoot kept Java relevant—while others faded.
