Nona’s Kitchen – JavaScript

Good morning! It is Sunday of the Thanksgiving Day 2020 weekend. Time seems to be passing by quite quickly. Earlier this morning I was reading an article regarding the Pfizer COVID-19 vaccine. It seems that there are still some items that need to be addressed before that vaccine becomes readily available in the USA. Accordingly to the article, we should achieve herd immunity summer 2021. Let’s keep our fingers crossed. In addition there are many other laboratories that are about the same stage as Pfizer. It is safe and reasonable not to depend on a single source.

While I was about to finish editing this document and getting ready to post it, my wife called me to go grocery shopping to Trader Joe’s. On weekends, unless I get up earlier (around 04:00 AM), I typically have time to work on a single 2-hour block. I can extend the block if needed, but if I am doing something with my wife, that tends to put an end to work on that day. Continue reading “Nona’s Kitchen – JavaScript”

First Web Application – Node.js

Hope you are having a nice day. Today is Tuesday. Unless I am mistaken, it has been three weeks since Election Day and as far as I know the results for the presidential election are still up in the air. Hopefully we will find out the results in the next few days.

Next week is Thanksgiving Day. My wife and I were planning on having very few people over, but after further deliberations, we decided that we will skip and celebrate Thanksgiving 2021 with family and friends. Based on what is going on with COVID-19, it seems that a few vaccines will be made available early next year. By November 2021 we expect that most things would be back to normal; that is, the new normal. Continue reading “First Web Application – Node.js”

Simple and Second Web Servers in Node.js

I am about to call it a day. It is dark and cold (25 F) in the Twin Cities of Minneapolis and St. Paul. I am in my office attempting to finish this post while my wife is upstairs in the living room wrapped in a blanket. Tomorrow morning we will wake up to a balmy 12 F. What else can I say?

I am reading and experimenting with the content of the book “Get Programming with Node.js” by Jonathan Wexler. I am currently on page 55. Expect to be done with towards the end of next month. At that time I will switch to experiment with Deno. Then I will move on to generate and post a first pass of a storage server. It should be a lot of fun. Continue reading “Simple and Second Web Servers in Node.js”

REST API

It is another average fall day in the Twin Cities of Minneapolis and St. Paul. It is sunny and cold. Two more days for the weekend; not that it matters because we are still in the COVID-19 pandemic. That said things appear to be getting better. Hopefully a vaccine will be available soon and we will all get into a new normal.

I am still reading the book Hacker’s Delight by Henry Warren. I have a couple more chapters that I would like to finish before putting it down and starting Get Programming with Node.js by Jonathan Wexler. As I mentioned a few months ago, I will be working on a storage project for my blog. I will start with the APIs and database interface. I decided to use MongoDB for the metadata and the file system for the data. The server part code will be implemented using Node.js in JavaScript. After we have the base functionality we will split the software to work on multiple servers. Once that is done we will move to place the modules in Docker containers and will manage them with Kubernetes. Once all is well, I will see if we can move it to the Azure cloud. After that we will create and integrate additional features. Continue reading “REST API”

Debugging React Applications

The temperature in the Twin Cities of Minneapolis and St. Paul in the past couple days has dropped a few degrees. We just started the month of August which should be midsummer. My wife always says that around the birthday of one of our sons (which is around mid March) fall arrives. I do just do not want to believe that summer is almost over. To tell you the truth, COVID-19 has not helped and to top it off this year the Minnesota State Fair has been cancelled. The fair is what marks the end of summer around here. Continue reading “Debugging React Applications”

Styling React Components and Elements

I continue pushing forward with the React course by Maximilian Schwarzmuller by O’Reilly via my subscription with ACM Learning.

Today is a nice summer day in the Twin Cities of Minneapolis and St. Paul. The private streets in the neighborhood where I live are being redone. Part of the work is on gutter drainage, some on replacing some of the curbs and finally a fresh double coat of asphalt. Today’s work started shortly after garbage and recycling trucks picked up their corresponding items. After the trucks left, noise and dust were all over the neighborhood. Right now all is quite. Not sure if they are done for the day. The final asphalt will be deposited on Wednesday. Continue reading “Styling React Components and Elements”

Combinations

Hello gals and guys! It seems that during the COVID-19 pandemic time goes faster. It is Saturday and the work week went by in the blink of an eye.

This post was motivated by a HackerRank problem which I am getting ready to tackle. I decided to experiment with combinations and factorials to make sure that a brute approach to the actual problem would be futile. In my next post will tackle the basis for a better approach.

As usual let’s start with some chitchat. Continue reading “Combinations”

Understanding the Base Features and Syntax – React

The COVID-19 pandemic started in Wuhan, China continues to infect and kill people all over the world. As of today Wednesday July 08, 2020 the world total confirmed cases and deaths are 11,900,855 and 545,728 respectively. Of course these numbers include reports from countries that are estimating (e.g., Peru and most Latin America countries) and countries (e.g., China) that for their political and financial gain report bogus numbers. Hopefully better treatments which will drastically reduce the symptoms and general public access vaccines will become short term realities. In the mean time, remember to wear a mask and gloves and keep social distancing. Continue reading “Understanding the Base Features and Syntax – React”

Refreshing Next Generation JavaScript

Once again, it is Saturday. We are experiencing the COVID-19 pandemic and it seems that days, weeks and months are flying by. My routine on workdays has not changed at all. I work five 2-hour blocks with most intermissions of about 15 minutes. The intermission for lunch is about an hour. Actual lunch takes about 20 minutes, but my wife and I sit down with a cup of espresso and chat for about 20 more minutes. When done we do the dishes and I go down to my home office.

Today my wife and I were going to go to Costco in Minneapolis. Last night I sent my son a message so we could meet there at 07:00 AM and chat while shopping. Last evening my wife had some stomach pain and a light fever. We decided to play it safe and stay home. If the fever persists until tomorrow, we will get an on-line medical consultation. Hopefully it is not COVID-19. Continue reading “Refreshing Next Generation JavaScript”

React or Angular

It is already summer 2020 and some people are saying that it does not seem that summer is here yet. Due to the COVID-19 pandemic the transition from spring to summer did not materialize. To me the big thing is that when summer starts days start getting shorter. Living in a suburb of the Twin Cities of Minneapolis and St. Paul we understand what short days in winter feel like.

As you know I am a promoter of never stop learning. A few post back I suggested a project on the Travel Planner System post in this blog. I thought that I listed the technologies that I will be using so I can refresh and catch up with new features before starting the design and implementation phases. I went back to the post and determined that there is no table. Continue reading “React or Angular”
