My courses are a bit different
For starters, I'm on camera. That can be a good or a bad thing, depending on your opinion of my face, but - for me - it was an important thing to do.
I feel that being on camera helps provide integrity, fosters trust, and builds rapport. Studies have also shown that seeing the instructor improves student engagement .
You'll see me more in some courses than others. When the content is abstract, I'll be providing very hand-wavy on-camera explanations (for a real giggle, watch on mute at 3X while streaming some dance music). Lessons on more concrete topics like specific APIs, or working through lab solutions, means I turn the camera off and present my screen instead.
Just be glad that - at least for now - I'm only recording in 1080p and not 4K.
In addition, I focus on the fundamentals first. It's incredibly important to be aware of what's happening behind the scenes if you're going to be using Elasticsearch in an enterprise environment. Data can be the most important part of your organisation so knowing how it's stored is vital to success.
I know it's not always actionable and you've got work to do but I promise it'll save you work in the long-term.
