Bootstrap Jumbotron

It is a beautiful Saturday in the Twin Cities of Minneapolis and St. Paul. My wife and I will be going for a 5 mile walk later this morning.

Today I woke up around 04:00 AM. It was somewhat warm at home. Turned off heating and opened a window. Since then the inside temperature had dropped to a more comfortable 68 degrees F.

This morning I read a post titled The Middle Class is being Disrupted by the One Percent by Michael K. Spencer on Medium. The post is quite interesting to me. The reason being is that I have been thinking and discussing with friends and family similar ideas. Something needs to be done by companies and governments before Capitalism and Democracy becomes a chapter in a history book. Continue reading “Bootstrap Jumbotron”

Java Lambda Expressions

http://(https://hackernoon.com/tensorflow-is-dead-long-live-tensorflow-49d3e975cf04This morning I read the post on Medium named “TensorFlow is dead, long live TensorFlow!” by Cassie Kozyrkov who is a Chief Decision Intelligence Engineer at Google. After lunch will spend some time watching the videos embedded in the post and over the weekend will see if I can take TensorFlow 2.o on a Linux machine for a spin. I have a version of TensorFlow 1.0 installed on a Windows machine. Followed some tutorials but as Cassie puts  it so expressively, it was complicated to say the least.

BST Diameter

Earlier this morning I read a post “Binary Tree: The Diameter” by David Pynes. The post showed up on Medium but was initially written for Towards Data Science. After quickly reading the post I decided to spend time reading the article in my computer, thinking about it and writing a solution in Java. The original article used C++.

Binary Tree – Heap

I read an article or two from Medium every day. A few days ago I read “Binary Trees: The Heap” by David Pynes. The idea behind a binary tree or heap is to be able to associate values with associated priorities. For example, assume you are in line at an emergency room in a hospital. When you arrive and register the facility may use a plain queue (FIFO) to wait for a physician. What happens if a patient in worse condition that you arrives later. The logical thing would be to allow them to see a physician before patients that are less ill. Continue reading “Binary Tree – Heap”

Simple Problems in Python

Last week I was reading a post on Medium “First Steps in Data Science with Python NumPy” by Kshitij Bajracharya.

What called my attention is his opening statement “I’ve read that the best way to learn something is to blog about it”. I believe Kshitij hit it right on. The reason I agree is that I have been a believer in “If you can’t explain it simply, you don’t understand it well enough”. This quote is attributed to Albert Einstein.

Using Docker – Installation

If you follow me on Twitter (@john_canessa) you have noticed that in the past couple months or so I have been posting tweets regarding articles in Medium. The site is geared to creating posts which you could do using your own web site (e.g., www.johncanessa.com). The beauty is that many talented individuals in different fields are posting there. The site organizes them by categories and presents the articles indicating the estimated reading time. One of these days I will probably start posting there.
