I’d like a self-contained, Maven-driven demo that shows how a Wildfly 20 Java servlet can talk to three separate mobile authenticators—Microsoft Authenticator, Google Authenticator and Duo Authenticator—and report back the outcome of each challenge. Scope • Focus exclusively on “second-factor” calls: how the servlet initiates a push / TOTP / Duo prompt (the “sending signal” part) and how it parses the success, timeout or failure response that comes back (“receiving results”). • No UI polish is necessary; a simple JSP or REST endpoint that prints JSON or plain text is fine as long as the code flow is clear. • Keep the sample lean but complete: working source, config files, and any required libraries or REST c...

Our property, Mortons at Russell’s Bridge, needs a premium logo that feels as enduring as the land itself. The Morton Bay fig tree is the heart of the design—it’s the most recognisable feature on the farm and must take centre stage. I’d like our livestock (Angus cattle, sheep and Welsh ponies) woven in only if they can be integrated subtly without stealing focus from the tree. The finished mark should work flawlessly in black-and-white; any shading or texture you add has to translate cleanly to single-colour use for signage, embroidery and screen-printed merchandise. Because the logo will appear everywhere—from the gate sign to hats and feed bags—I’ll need fully scalable vector artwork and clear usage guidelines. Deliverables &bul...
