A smiling person stands barefoot on a grassy lawn in front of lush green shrubs and small trees under a clear sky. They are wearing a blue knit beanie, glasses, a navy zip-up jacket with a “Docker Captain” logo, and denim shorts. Holding a sign featuring a cartoon bird and the words “Docker Captain,” they pose with one foot raised on a low mound, looking directly at the camera. The outdoor setting appears sunny and relaxed.

Veranstaltungsbanner der Hochschule Weiden: ‚Dev-Stories mit Lerneffekt: Was schief ging und was half‘ am Freitag, 13.03.2026 um 10:45 in Weiden, Deutschland. In der Mitte ein Porträtfoto des Referenten Johannes Rabauer, der draußen an einem Laptop sitzt und lächelt.
A comic style illustration shows a cracked Hibernate logo made of gold and gray geometric shapes, with handwritten SQL queries spilling out from the fractures. Next to it stands a skeptical cartoon software developer with exaggerated features, round glasses, a short beard, and crossed arms, wearing a hoodie. The developer side eyes the leaking SQL with a doubtful expression, highlighting the joke about ORM abstraction hiding messy database queries.
A smiling man wearing glasses, a black t-shirt, and a lanyard points to an Oracle ACE Associate certificate. The certificate is awarded to Johannes Rabauer in recognition of technical and community leadership contributions to Oracle communities from July 2024 to August 2025. It is signed by Gerald Venzl, VP of Database Product Management, ACE Program, and dated September 2025. In the background, there is an illustration of a golden trophy with a spade symbol.
Comic-style illustration in the vibrant, exaggerated style of *Asterix & Obelix*, showing a bearded man with short hair and round glasses (based on the provided photo) in Roman-era tunic and sandals, charging forward with a clenched fist toward a towering glowing blue cyberpunk robot. The robot has holographic armor, neon circuitry, and emits a bright blue light. The scene takes place in a large Roman arena with sandy ground and tall stone walls, packed with a cheering crowd holding humorous banners that read “Make a custom model!” and “Limit the tokens!” Motion lines, dust clouds, and expressive poses emphasize the action, with warm daylight contrasting against the robot’s neon glow.
A bearded man with glasses sits at a rustic wooden table in a warmly lit log cabin, his flat hand hovering over a large red “STOP THINKING” button connected by a thick cable to a plush brown bear labeled “qwen3.” The bear’s eyes glow bright blue like a robot, and above its head floats a holographic busy indicator. A thought bubble with three dots hovers over the man’s head as he focuses intently on the bear.
A digital illustration showing a three-part progression: on the left, a man with glasses types intently on a keyboard in a dark, sci-fi environment with glowing code behind him; in the center, a futuristic AI robot with glowing blue eyes monitors a laptop; and on the right, a hooded Dungeon Master with glowing eyes stands over a fantasy map and a floating D20 die, with a speech bubble saying, “Prepare to enter the dungeon...” Blue glowing arrows connect each element from left to right, visually representing the flow from human coder to AI to fantasy game master.
