[Stefan Moore]

1. AWS stuff
2. How to keep the death grip on a remote control

@michaeltharrington whats on your learning agenda?

Sorry for the hold up... I actually took off for the holiday and just returned late last night.

Lol, loving your #2 goal. 😆

Anywho, what am I learning on? Let's see... over break, I was teaching myself how to make beats on a Teenage Engineering Pocket Operator (PO-33 sampler) and created a little lofi hip hop version of Bing Crosby’s “White Christmas” using just the PO-33 and my Moog Grandmother (synth).

Here are two versions of it for ya to check out:

• Lofi White Christmas (Smooth Pocket Operator Version) - this is the song being played as is from the Pocket Operator
• Lofi White Christmas (Psychedelic Grandma Version) - playing the audio from the Pocket Operator into my synth to get strange effects and then recording it to my computer.

Aside from music-making, I've just been chilling... can't say I have loads on my learning agenda at the moment. However, I'm trying to think of something good to focus on in the new year — always good to keep growing!

I like the second one better sounds slightly more upbeat. The idea of what to do in 2024 will come to you as you already know the answer and it's already in motion.

Thanks a bunch, Stefan! 🙂

Lots of Leetcode. Trying to get better at some somewhat advanced topics.

I learnt two things. Firstly, Apple TV+ is offering two months free for new and returning subscribers, perfect for binging this festive season.

Secondly, I learnt about the lru_cache() function in Python. No idea why I didn't know about this before.

I am learning the book 'grokking algorithms'. It looks interesting.

Learning ReactJS.
My current understanding of what React is doing under the hood.

• DOM operations are expensive and verbose.
• ReactJS has something called the Virtual DOM.
• Virtual DOM is like a lightweight in-memory snapshot of the real DOM.
• when an event occurs react triggers a re-render and creates a new virtual DOM tree.
• then it compares the previous virtual DOM and the newly created virtual DOM, known as diffing.
• Based on the diffing result react updates the specific elements in the real DOM that have changed.
• This helps in minimizing the DOM manipulation.

Batching
Batching is also one of the advantages of React where it batches together multiple state updates in a single render cycle.

-> My understanding about batching is that it is like the debouncing technique where instead of sending one backend request per key-stoke while searching for something we wait for the user to type multiple letters or wait for a set amount of time so that the user finishes typing and then send the backend request for that entire typed word or sentence. I might be completely off the mark here though.

Happy learning.
