7th Week-Progress

I have entered the 7th week since my fatal decision to become a master coder. What progress can I report?

   I finished The Odin Project's Web Development 101 course on Monday and began the third course in curriculum : "Ruby Programming". Although I completed the Codecademy Ruby course and did some other Ruby work a few weeks ago, I felt I needed a review. 

To this end I am redoing the Codecademy course, I completed Chris Pine's book  Learn to Program,  and I reread Chs.2 + 3 of Peter Cooper's Beginning Ruby

Needless to say, the revision was worth it- I have a much clearer understanding of blocks and procs, as well as hashes and arrays.


Concurrent with the Odin Project I am working through the Epicodus curriculum. It is always helpful to have multiple perspectives on a subject.


I have also discovered an intriguing course called FreeCodeCamp. It isn't complete yet, but the aim is to train students to write code for non-profits. Much of the curriculum mirrors The Odin Project, but there a few new resources such as this one for HTML/CSS.


As I mentioned the other day, I have been doing daily Java workouts (using the Coursera Java course). Most of the exercises are maths focused and are useful reviews of Java syntax.

The challenge today was trying to forget how humans do matrix multiplication and explain it to Java without using any fancy inbuilt methods. In the end, I did use the array.length method as it was the easiest way to create the product matrix.

I've also been using a new Pomodoro app to motivate myself and to record my working time. I sometimes forget to turn it on after the alarm has gone, so most days on the graph are underestimates. The app also discards any minutes that aren't part of a complete 25 minute session. So if you've done two 20 minute sessions and were interrupted, there will be no record of that time.

Anyway, here are the first 10 days:

Einstein's Logic Puzzle (SPOILER ALERT!)

On Monday I began working through a Discrete Math textbook in preparation for some courses I'll be taking in January. There was a beautiful logic problem in Chapter 1, apparently created by Einstein. This is one version of it: Five men with  different nationalities and with different jobs live in  con secutive houses on a street. These houses are painted  dif ferent colors. The men have different pets and have   dif ferent favorite drinks.  Determine who owns a zebra and  whose favorite drink is mineral water (which is one of the  favorite drinks) given these clues:  The Englishman lives  in the red house.  The Spaniard owns a dog.  The Japanese  man is a painter.  The Italian drinks tea.  The Norwegian  lives in the first house on the left.  The green house is  immediately to the right of the white one. The photogra pher  breeds snails.  The diplomat lives in the yellow house. ...

Job as Entry Level Developer

After 4 months of work, sometimes focused, sometimes not, I accepted a job as an Entry Level Ruby on Rails Developer yesterday. This is after starting with zero knowledge on November 1, last year. Beyond knowing a little about coding (but getting the definitions of  REST and AJAX wrong), what were the reasons for the job offer?  I think it was the meetup group I started in January that made me stand out from the rest. The motivation for the meetup group was to help me become a better coder and to indulge my teacher instincts. After some initial meetings at the library and my home, an IT hub in town offered to host us. This meant extra advertising and prestige for the group. After announcing the meetup group at an Agile meetup group for developers, I got some volunteers to give talks. The first volunteer offered a talk on Ruby. As I was comfortable with Ruby I prepared a coding tutorial .  After the tutorial, which was attended by some beginners and some a...

Algorithm Analysis - 1

Currently, I'm learning to perform algorithm analysis using Big-O notation. In one resource I found the following problem: You just dropped a box of glass toys and  n  toys in the box broke in half. You'd like to match the halves of the toys so that you could glue them together, but the only way to tell whether two halves belonged to one toy is to physically pick up the two pieces and try to fit them together. Express how long this matching process will take in terms of  n . The answer given is n^2 (n squared) with the following explanation:  You have to compare every piece with every other piece. If you have 1 toy and it breaks in half, you have 1 comparison to make. If you have 2 toys and they both break in half there are 4 pieces and you have to do 6 comparisons. If you have 3 toys, there are 6 pieces and you have to do 15 comparisons. If you have  N/2  toys, you have  N  pieces and you have to do N-1 + N-2 + N-3 + ... + 1 =(N)(N-1)/2...
