`Day27`
• Halfway through Lesson7 
    ◦ issue with _notifyDataSetChanged_() - screen updates even if the modified item is off screen. 
        ▪︎ can lead to performance degradation, unsatisfactory user experience due to flickers while scrolling
    ◦ _DiffUtil_ - Helper for RecyclerView adapters that calculates _changes_ in lists and minimizes modifications
    ◦ Updating Adapter to use _data binding_
        ▪︎ wrap with &lt;_layout_&gt; tag, put &lt;_data_&gt; inside (should _rebuild_ after then!)
        ▪︎ _BindingAdapter_ - adapter that adapts the application data into something data binding can display on the screen
    ◦ _RecyclerView_ use _LayoutManager_ to control and modify the layout strategy
        ▪︎ LinearLayoutManager, GridLayoutManager
• Etc. memos
    ◦ (recap) _Data binding_ - Creating an object that connects, maps, binds two pieces of distant information at compile-time, instead of runtime. Allows us to easily observe &amp; show the data to the UI from a data source. 
    ◦ (recap) “_inflating_” a layout refers to converting xml layout view into memory’s kotlin view object.
`Self-Comment`
• RecyclerView seems to be quite important. Hoping to get used to it. I should learn how to use android profiler. Want to check rendering time, cpu usage etc. of using RecyclerView vs. others
• Lovely weekend, enjoying daytime in some beautiful office, afternoon cleaning my dirty room... Spent only three-four hours of working time, but it was productive.
`Goals Tomorrow`
• Finish lesson7, Spend some time organizing thoughts before Monday. (Lunch is planned with the CEO of startup I'm about to work in,,) Though it's not a formal interview time, I must be prepared &amp; be ready to clarify basic stuffs
