Although the article was not originally intended to be about the following topic, trusting in the associative skills of the gentle reader, let's get a little nostalgic!
So, well... for those of you who aren't old enough, just imagine the following:
Sometime in the early eighties, when the long-awaited May Day and the May Day parade arrived on the Shipyard Island in Óbuda, the attentive employees of the company's trade union awaited the factory workers who had been tired from the parade with tables spread out. The parents were treated to lukewarm beer, and the children to warm, bottled colas in countless quantities. The usually grumpy kitchen lady also smiled, cooking industrial quantities of hot dogs and sausages in a Beelzebub pot on a scary gas burner, there were liters of mustard flowing, and baskets of freshly sliced bread. The forklift driver and the chief engineer sat next to each other on the beer bench exposed to the sun, surrounded by children's noise, flags fluttered small and large, colorful balloons swayed in the wind, music, joy, laughter, and of course, the inevitable KOREAN RACE every year!
As we stood in line for another ride, as a little boy with a technical interest, the carousel stuntman was burned into my retinas, as he leaned loosely against the carousel's painted central iron structure in a dirty muscle T-shirt, with an extinguished cigarette in the corner of his mouth, and a beer bottle in his left hand. However, he performed the real stunt with his right hand, when he slowly rotated the palm-sized electrodes into the container containing the finger-sized black cables, the soda solution liquid starting resistor, dosing the voltage to the rotor of the old asynchronous motor with artistic precision, which caused the carousel to start creaking and, after a while, centrifuged the screaming gentleman audience above the crowns of the trees. The hours passed, the midday sun and bottled beers made the gentleman in the muscle shirt braver and braver, the electrodes sank faster and deeper, the smoothness of the start decreased, the centrifugal force increased, so that by evening the carousel almost resembled an extreme sport, to the great joy of the children and the sincere horror of their mothers.
How did this come about? In recent years, during VMware trainings, especially in the case of vSphere courses, a formulaic similarity that is understandable to me can be observed. I stand like a quasi-muscle shirt stuntman leaning on the iron structure of the education, and although after conducting so many online trainings without a camera, I could admit to the beer and the cigarette, I prefer to stare at my right hand, with which I swirl the electrodes into the soda solution. Since the first round of new entrants were organized into this round, we start carefully and I spin them in a prescribed and safe manner to the point of screaming. Some of them get off with green faces, their companions hug and comfort them at the end of the round, others would immediately pay for the next one with a smile on their face.
The first round is always the vSphere Install, Config, Manage course. A cautious start, a foundation, and at the end, everyone who lands can say that they've been around the block, they could have survived, it wasn't that dangerous.
However, the hard core, those waiting for the next, more advanced round, are gathering under the colorful light bulb-lit sleigh bells of the cashier booth. When enough of them have gathered, the cashier with her strangely blurred eye makeup winks at them: You're coming! The enthusiastic army of experienced carousels rushes to the carousel, everyone finds their place, and excitedly sits down. The guy in the muscle shirt throws down his cigarette butt, puts down his beer, walks around, and transfers a few kids to the carousel for better and more even weight distribution. This is scary in itself, but if the guy is serious, what's next? They're all sitting in the swings, the safety chains are on, the music stops, the birds are frozen in flight, their little sweaty hands are gripping the decades-old chains... I just have to survive this, how stupid am I, I shouldn't have paid for speeding.
The second course is the vSphere Optimize and Scale course. Just don't be too careful! Anyone who pays for this can watch up close as the operator in the muscle shirt, with a cheeky smile on his face, dips the electrodes into the soda solution with one firm movement. The hum of the asynchronous motor and the squeak of the V-belts blend with the creak of the screwed iron pipes as the old structure starts to rotate. The passengers rise higher and higher with wide eyes, the chains holding the red-painted swings almost horizontally. Now they don't really scream, they rather experience, even live the moment. All of it. The large central column spins with friction, the air rustles past the chains. This course is just as long as the previous one, while the mothers watch their children spinning on the carousel with concern, the fathers try to recall their studies on the shear and tensile strength of metal structures. Forgotten bottled beers slowly warm up when left in the sun.
A bell rings, the ride is over, the drive stops, the mechanism slowly stops. The passengers acknowledge with a faint half-smile that they are standing on the ground again, even if they are a little unsteady from dizziness. The operator in the muscle shirt lights up and pats the backs of the little heroes getting off the swings one by one in appreciation. He looks at them with completely different eyes than before the ride, and the impressed delinquents can feel this. It is clear from his nod, because who never says: That was great, kids! Now you have really swung around, the way you should.
On the way home in the evening on the HÉV, every carousel hero is wearily staring out the window at the evening Danube bank passing by. Finally, there is time to process those few minutes of the second ride! However, there is one among them who, beyond the memory of the speeding spin, is constantly wondering how the hell that stepless fluid resistance works? It was really cool when the uncle operated it. When he learns about it in school years later, he is horrified to see what a life-threatening device it is.
After all, the metaphor has lasted so far. I sincerely apologize to those who may not have been able to identify with any of the members of the aforementioned army of children. As a consolation for them, I will tell you that I myself, the carousel operator :-), recorded the exercises of both rounds, that is, both vSphere courses, i.e. Install, Config, Manage and Optimize and Scale, which, spiced with some explanations, are available for three months and can be viewed in video format for those students of the training center who have completed the given course. This way, it may be easier to recall what you heard or prepare for the big test, the VCP exam.
