Hobby project - Store and view exchange rates

Image
By
The next step in my project was to test out being able store and display the rates in a database. I decided to use nodejs and supabase for this. Everything worked beautifully. Only hickup was the following error due to my package.json not being correct.

SyntaxError: Cannot use import statement outside a module

Added this to package.json

  "type": "module"

This works beautifully. Right now I am just testing fragments of what could be part of a bigger system to see what is possible and what works and how easy to code on a mobile. There is no fully functioning integrated end to end system just yet.



This is also what I tested. A serverless append-only database using GitHub + Actions + Pages. That’s basically a lightweight backend system. This was the ChatGPT prompt I used.

Guide me through each step. This is what I want. A manually run github actions that adds to docs/data.json with the current date and time. docs/index.html displays all the entries in data.json.

Make sure and give the action permission to write to repo or else you will get an error like this - remote: Permission to hassan-theitguy/update-data-test.git denied to github-actions[bot].

To avoid caching issues I tried the following in my javascript - const res = await fetch("data.json?v=" + Date.now());



I also asked ChatGPT the following - I have been doing some hobby coding. Things I have tested so far. Scraping a website for exchange rates and serving the data via my api. Emailing and sending the data via email and sms. Storing data in supabase and displaying it in a webpage. What else can I test out?

And the response - You’ve already covered a really solid “full loop” stack: data ingestion (scraping), processing, storage (Supabase), delivery (email/SMS), and presentation (web app). The natural next step is to start adding complexity in systems, not just more features.

Motivation

By
It is 150pm and I have decided to write. I have no topic to start but I feel like writing. While trying to decide what to write I saw this question that had my interest, what motivates you to keep going even when life is difficult? The first thing that popped in my mind was God. But I do not think the answer is simple or singular. I also think I need to put some thought into this. Also what is the relationship between motivation and discipline? Motivation is easy but discipline is hard. I think for me motivation comes from the joy of success. But God was my first answer. Now that God is the focus of my life, the joy of success becomes being a success in the eyes of God. But I said the answer was not singular. So different things motivate us at different times but they all lead to wanting to succeed. This reminds me of the Muslim call to prayer that says come to success. If motivation is what calls you then success calls you and success gives you joy. My friend Chatty says that what I h...

Mental health matters

By
It is 547am and I have decided to write. I have been living with a mental health diagnosis for more than 23 years. I am differently abled. Mental illness sometimes presents itself as a non-visible disability. A person with mental illness may look and function normally. Added to that we do not get to see the struggles happening internally. After 23 years I could say that I have much experience with my condition and may be able to offer words that may help others. There is plenty of stigma associated with mental illness. People think that the mentally ill are bad people, weak, or somehow less deserving of dignity and the treatment of the illness sometimes feels like punishment and is dehumanizing at times. There is plenty of good intentions and well meaning as well (do not get me wrong) but things could be better. And it happens at the highest level. A leader once said, "Whom the gods would destroy, they first make mad." As the saying goes, who knows it feels it. I started a pr...
