Hobby coding project - exchange rate api

I used ChatGPT to provide the guidance. Basically I created a serverless api endpoint (using Vercel) to share the exchange rate data from the front page of the central bank website. I will contact the Central Bank to ask if they plan to provide public APIs for their data in the future.

The project uses Axios + Cheerio, the Requests + BeautifulSoup of the Node.js world. Axios handles HTTP requests with a clean promise-based API. Cheerio provides jQuery-style HTML parsing without a browser.

So my api endpoint serves up json exchange rate data. Next, what I did was create a Github actions to read data from the api endpoint and send it to my email address. I used resend for this and nodejs. Now I could easily send the exchange rates data to my email address on a daily basis by scheduling the action in Github. Next I am going to test out sending the data via sms if I can find a good free sms sending api.

See results below.

Recursion example with SQL

I asked my friend Chatty, can you use recursion in SQL? For example I have a table (ID, value) ordered by increasing ID. Can you guide me through using recursion to select all the rows of consecutive repeated values using and creating an SQLite database. Provide the small sample data. Is there a better way to do this? A More Modern Alternative (Window Functions) In real-world SQL, this problem is usually solved more efficiently using window functions like: LAG() ROW_NUMBER() SUM() OVER But recursion is excellent for learning traversal logic and hierarchical thinking. Recursion example using sqlite on termux DROP TABLE IF EXISTS sample; CREATE TABLE sample (     id INTEGER PRIMARY KEY,     value TEXT ); INSERT INTO sample (id, value) VALUES (1, 'A'), (2, 'A'), (3, 'A'), (4, 'B'), (5, 'B'), (6, 'C'), (7, 'A'), (8, 'A'), (9, 'D'), (10, 'D'), (11, 'D'), (12, 'D'); WITH RECURSIVE grouped AS (    ...

Bless us today

It is 515pm and I have decided to write. Today is the day before the holiday and it feels like a Friday. I did not feel like doing anything this afternoon. But I got up and made dinner. Then brush my teeth and bathe. A round of applause to all of us for being alive and making it through the day. There are many things we can applaud ourselves for. There are many things we can applaud others for. It is good to pat ourselves (and others) on the shoulders now and again. Life is not easy. No one has it easy. Comfort is an illusion. But God is real and so we pray. It is 214pm on the following Monday and I have decided to continue my writing. I have this thought. God is holding my hand and we are walking. Walking in empty space. I closed my eyes and selected a verse from the holy Quran. I landed on surah 94 verse 5 - so verily with hardship there is ease. No matter how and when we are tested we must remind ourselves of the goodness of God. God is not going to leave us stranded and empty hande...
