[Day 171] Data engineering zoomcamp by DataTalksClub

 Hello :)
Today is Day 171!


A quick summary of today:
  • completed IEUK by Bright Network


Firstly, about the data engineering zoomcamp

I know they deliver good content, and ends up with a solo project that will be a great addition to my portfolio. 

This is the camp overview:

Tons of new things to learn, some old friends (in mage.ai), kafka, dlt, spark, dbt. It was a no brainer decision. So I guess at the moment on different days of the week (I need to set up a schedule) I am taking their data engineering camp, their MLOps camp, and LLM camp. 
As for covered material for today~
Learned about docker, and using postgres on docker. 

Created this dockerfile

And then below are some of the ran comands and steps covered.

Start the postgres server on docker

And access it through the terminal
pgcli -h localhost -p 5432 -u root -d ny_taxi

Then, using python, I uploaded data and I could query it from the terminal where I ran pgclie

For better user experience, I started a pgadmin server in docker

And I could access it on port 8080, however, I could not add a connection to the created table. This is because the two docker instances (postgres and pgadmin) were not connected. To connect them, I used:

docker network create pg-network

And then I ran the postgres and pgadmin docker containers in 1 network

And I could make a connection, view and query the data in pgadmin

However, the above two commands required me to run them in 2 separate terminals. To make this a bit more convenient, I used docker-compose. 
We first set up a docker-compose.yaml file

And *now* I understand what is going on inside this file, and what docker-compose does for us - it combines containers. Awesome!

There are a few videos left from module 1, but everything from today, incuding my command docs are in Module 1 of my repo.

Secondly, for IEUK by Bright Network

The event ended with the submission of some kind of a work sample where we act as a product manager. 

I can share a bit of mine. It is the product roadmap that I developed. Overall it was a good exercise because those are new things for me ~



That is all for today!

See you tomorrow :)

[Day 198] Transactions Data Streaming Pipeline Porject [v1 completed]

 Hello :) Today is Day 198! A quick summary of today: data streaming pipeline project [v1 done] Here is a link to the project's repo. Well ... I did not know I can do it in a day (~14 hours) after yesterday's issues but here we are. Turns out in order to insert the full (~70 variables with nested/list structure), I need the proper pyspark schema. And yesterday I did not have that and that is why when I was reading data in the kafka producer I was getting NULL in the columns - my schema was wrong. Well today I not only fixed the schema for the 4 variables I had yesterday, but included *all* the variables that come from the Stripe API ~ 70 (for completeness).  When I run docker-compose, the data streams and is input into the postgres db (and is still running). Unfortunately, the free Stripe API for creating realistic transactions has a limit of 25, so every 3 seconds, 25 new transactions are sent to the db. It has been running half the day (since I got that set up) and as I am wr

[Day 107] Transforming natural language to charts

Image
 Hello :) Today is Day 107! A quick summary of today: created text2chart - transforming natural language to charts [ github ] [ webapp ] I am super sick, but in the around 3 hours of my fever not being high, I managed to study a bit. I was again thinking about creating some nlp project but was stuck on the idea of how to host a model. After looking around I found this article where they create a similar app called chat2vis  and they use codellama. I know codellama is an open source model that I can get from huggingface and I wondered, how did they host it. Turns out - they ask the user to input a huggingface api key, which then allows for querying and generating content. (AWESOME! this is applicable to some of the other PDF chat apps that I have, but I will look to make an app of them later).  My fever eased a bit, and I sat on my chair to do some work ^^ Here is a breakdown of the app. I used streamlit. Also, 2 default datasets during dev: Financial Statements of Major Companies(2009-

[Day 54] I became a backprop ninja! (woohoo)

Image
 Hello :) Today is Day 54! A quick summary of today: Read through cs231n's neural network lectures [1] [2] [3] Spent 8 hours going over Andrej Karpathy's backprop ninja tutorial After yesterday's confidence boost in doing backprop, I came in today with the intention of becoming of, as Andrej Karpathy calls it, a backprop ninja.  The cs231n NN lectures were the usual about how NN became to be, param initialization, activation functions, loss functions, regularization and optimizers. Nothing out of the ordinary, but still was good to reassure myself of that knowledge. But that was definitely not the main even of today. As I mentioned, I wanted to become (or at least attempt to become) a backprop ninja today. I have watched that particular tutorial twice, the 1st time I had no idea what is going on, the 2nd time I could follow, and now it was the 3rd time - and now, I wanted to participate and actually see the why and the how of the things we have to do, when we do manual back
