A look at Google Colaboratory (While Building a Stock Portfolio)



After the group effort heard 'round the world in 2021, stocks are on everyone's minds. I didn't have money in GameStop, but I did have money in AMC from 2020.

I bought it right as most theaters were closing from the Coronavirus pandemic and it was extremely cheap.  

Why? I like the moviegoing experience! As of March 6th 2021, many AMC Theaters in New York City and State are reopening at 25% capacity.

I'm still holding onto the stock - It never rose as high as GameStop's - but you won't see me at any theaters so soon.

Onto today's topic: Google Colaboratory is a cool tool, allowing you to run Python scripts right in the browser.  You can even install things into the environment! Is it a little container environment running my program? 


Here is the video, by Computer Science. And here is a video of me giving a brief look. It sends you right back here.

('Colaboratory' is a portmanteau of Collaborate and Laboratory. I love portmanteau names! 😊)

The video creator has the data they used behind a paywall (Understandable). I found another dataset here on Kaggle (which I'd never thought I'd use again).  A lot of the data has the same values with different names. 

If anyone has better data somewhere with actual variety, I'm happy to try it again.

I also branched out and made copies using various past data of companies from NASDAQ (Thank you to the multiple people who pointed me in that direction).

I changed the Index to the Symbol of the organization on NYSE. 


  • DIS 
  • SNE
  • MSFT
  • EBAY

Then removed it from the chart with drop - It was there under both "CQS Symbol" and "NASDAQ Symbol". Both were removed with the same line for code economy.

The code at 10:33 in the video doesn't work in mine:

Remember; This is not the same dataset as in the video, so the data doesn't correlate. I remove the troublesome (df) at the end of both commands and it works without them. I'm more interested in learning the tool and knowing the logic right now.


There is a code snippet library on the left - Everything from where to pull data from to visualizing scatterplots.



I really enjoy the Colaboratory. Being able to run snippets of code at a time without commenting out everything has helped me to understand Python better. The issue is having to rerun some previous commands to make sure everything is defined.

Contactless Tech’s Role in the New Guest Experience ft. Intelity and The George

 Contactless hospitality technology is growing. You want to get away, and you'll be damned if a little thing like a deadly virus will stop you! But you still don't want to touch things. Ew. During the chat between INTELITY CEO Robert Stevenson and THE GEORGE Director of Operations Kerrie Hunter, you’ll learn how the historic boutique hotel has adapted a mobile-first guest experience in the wake of COVID-19—and how they see contactless technology affecting the future of hospitality. I don't remember how I found INTELITY (probably hoping to score a position with them), but I liked them enough to stay on the e-mail lists.
