Bento for your mind while commuting on the grind

My commute to work is a 3-hour journey every day, with 1 hour on the train and half an hour on foot each way. Friends who visit me from the city always ask, “Do you commute like this every day? Aren’t you exhausted?” I thought this way too before moving out from the city, where I walked for only 10 minutes between home and school. But now, I am glad that I have 3 full hours of uninterrupted solo time every day, and the switch of environment between the fast-paced urban and the serene suburban life helps refresh my brain and reset my mind.

I prepare small “learning bento” before going to work, and spend the time on the train either watching MOOC (such as Coursera) and YouTube videos, or reading books and articles, and spend the time on foot listening to podcast or Audible. 3 hours a day adds up to 15 hours a week and 60 hours a month. And over the past few months, I have discovered a lot of great learning resources and would like to share with those who also like to have some “learning bento” for the mind while commuting on the grind.


I started to use YouTube for learning this year following a friend’s suggestion and was astonished that there are tons of great tutorials and playlists with vivid animation and clear explanation.  Here are a few channels that I subscribed to.


Coursera App allows you to download videos and watch them offline. I enrolled in one Coursera specification in the past few months: Data Mining, which covers text retrieval, search engine, pattern discovery, and recommender system.


There is only 1 book on statistics that I have been reading in the past few months.

  • Elements of Statistical Learning
  • Absolutely a must-read for any data scientist and machine learning engineer. It has a lot of equations and formula which are not easy to understand by self study. I usually watch some YouTube videos and read more intuitive explanation in order to have a good understanding of the book.

Research articles

To keep up with recent research development in the field and to understand certain specific research topics related to my project, I read research articles on a regular basis. My recent reading focuses on time series analysis and featurization, and word embeddings.

Social media and newsletter

I follow active members (both company or individual) in my LinkedIn network and they often post interesting development and news in machine learning, such as Towards Data Science

I subscribe to the newsletter Data Science Weekly and they send weekly newsletter about recent blogs, articles, and resources.


And of course, the pleasure of binge watching my favorite genre on Netflix: Sci-fi. Shout out to the Black Mirror fans!
