This is a tech video I came across today. And it inspired me. Ya, I was surprised too.

So what was it about the video that had this noticeable impact on me (and judging by the comments, everyone who has seen it)?

• First of all, the speaker is explaining a pretty complicated concept that has multiple sources of documentation online, all of them incomprehensible. The talk truly lives up to its boast of being in plain English.
• One of the ways he has done this is by analysing and acknowledging upfront, the reasons why the explanations presently available are confusing. For example, the fact that they use jargon which pre-supposes, incorrectly, that the reader understands all the terminology. He then proceeds to address these issues by clarifying the terms in the simplest language possible.
• He provides context by giving examples of software we consume which works on this concept under the hood.
• A very well-thought out flow diagram is used that explains the order and interaction between components clearly.
• The fact that every question from the audience corresponds with the subsequent part of the presentation is testament to how smoothly the talk flows.
• He demonstrates further using apps that reveal the details of each transaction step. I found this to be better than a real-world fully-formed app demo.
• Finally, his articulation and diction are spot on. I didn’t hear one instance of fillers like ‘Uh…’ and ‘Hmm…’. His free body language displays confidence and engages the audience.

The talk showed me the power of a well crafted presentation that is delivered skillfully. It has motivated me to try out what I learnt, just for fun. Above all, it reminded me of why I fell in love with this field in the first place.
