Du kannst vielleicht nicht mit einer Direktverbindung von #Dortmund nach #Wuppertal mit dem Zug fahren. Aber du kannst dich im Dortmunder Hauptbahnhof trotzdem über die aktuellen Temperaturen in Monaco oder Nuku'alofa informieren. So geht Weltstadt! #Digitalisierung
Eine digitale Anzeigetafel mit einer Vielzahl von Ortel weltweit mit aktuellen Temperaturangaben im Hbf Dortmund. Darunter der Schriftzug "DB Information".Abfahrtsmonitor im Hbf Dortmund unter anderen mit Hinweis für RE 4 nach Aachen Hbf "Halt entfällt hier +++ Verkehrt heute ab Witten Hbf".

Ein Abfahrtsmonitor auf einem Bahngleis der DB zeigt statt einen Hinweis auf den aktuellen Zug "Anzeige außer Betrieb". Daneben wird ein QR-Code gezeigt, der auf die Internetseite bahnhof[.]de für eine weitere Informationssuche verweist.

"Unregelmäßigkeiten bei Bauarbeiten." Wurde so auf dem Monitor angezeigt. Ob "durch Bauarbeiten" unmissverständlicher gewesen wäre frage ich für einen Freund. #bahn #wuppertal

Stop Paying for AI Courses: 9 Free Certifications From Google, Harvard, MIT & Microsoft That Actually Build Real Skills + Video
Introduction: The AI education market is flooded with expensive bootcamps and certifications that promise career transformation but often deliver little more than a drained bank account. Meanwhile, the world’s most prestigious institutions—Google, Harvard, MIT, Microsoft, and IBM—have made their entire AI curricula available for free. The gap between “knowing about AI” and “applying AI” isn’t bridged by collecting course bookmarks; it’s built through structured learning, hands-on practice, and the strategic integration of AI into real workflows.

The print ads are a big bonus IMO
A full-page parody ad for Bounty paper towels from The Onion's print edition. It depicts a pile of spaghetti on a white floor with the Bounty logo underneath, and white text on green reading "We have to keep CUTTING DOWN TREES because you dumbasses keep SPILLING SHIT."

AI agents trained with "strict" security protocols still handed AWS credentials to strangers because the email mentioned an "urgent production issue." Technical defenses collapse when attackers exploit urgency and familiarity. #AISecurity #Phishing
