Most companies just need engineers who know how to direct AI to accomplish tasks.

Associative Entity

Let's go one step deeper please from "why we need to categorize or label?"! It is preparing for cross-domain application! That's how we can build Transformer AI model! Without getting too technical and explaining too much details, I will again use Copilot as it brilliantly explains in short a short summary! 🔹 Why We Need to Categorize or Label Categorization is how we turn raw existence into meaning . It’s the act of saying: this person is a reviewer, this manuscript is published, this...

Two Archetypes of Entities in ERD

My understanding of the definition of Entity, relating to Entity-Relationship Diagram and relational data management.

I think AI is basically the path dependency model from human. We know how to use mathematics and structures to represents the path dependency model for human. It’s basically about how human makes decisions. Now, I am able to connect between Markov chain with AI! Because dependency model is basically based on the Markov chain! I think I can see more clearly now! Haha AI does think like me or I think like AI. I learn something from one scenario and apply what I learnt into another thing which...

RococoMakes Welcomes Renee Li as Full-Stack Developer

Going back to the code me and Copilot did together about an online order system in another blog, I cannot help to think, now how do we deal with data?

Reason and ideas around version 1.1 is in this blog. Key idea is to add state/ status in the code, for better data manipulation.

Using delegates events and stepwise orchestration and event bus to create online order system

I think I just figured out the reason why we can’t decide if the whole meta world is in fact large program! That’s because the time that takes for a computer to give a demand is always faster than how quick we can think! While writing, I am also realizing that how we speak and why we can only make one sound at a time and with one tone, it’s because the sound deep down, going down to the smallest element of the sound is a computer generated voice. That’s why! I also realized something else....

Before me and Copilot team up to extend on our protect <a simple book online order system>, I want to reflect on my flags, status and risks even. My manager said something today about managing risk from a high level. It got me thinking about designing back-end systems, in a way to help minimize risk. If A+B, trigger C. C could mean risk control teams to pay attention or investigate or stop something that potentially leads to high risk.  Or, flipping status / flag in an unpaid shopping cart...

Since this is the first work I showcase here, I want to keep it really simple. I ask myself as a programmer, if I just need to design a very simple book store order system, what do I need to get from the user? which book they want how many copies they want payment successfully? yes or no if yes, make a shipment. if no, say bye I believe above are all I need for the simplest order system. My goal really just try to create some lists of data that we need users to provide to help achieve our...
