Hackerrank world codesprint 9 - comparison study

January 29, 2017

Introduction

It is a long break Julia took in weekends, and she chose to do some study and practice on Hackerrank. Compared to her first 4 years experience from 2011 to 2015 to attend church small group activities in each weekend, she tried to build up a good habit to do some independent study on Hackerrank, programming competition.

She learned a tremendous team work through the church small group activities, through meeting preparation, lectures, small discussion, group activities. She learned the importance to help new comers to have a good study of bible each time.

Related to hackerrank contests, Julia also learned through the study, and track how other players work with hackerank. People with a lot of competition experience all come to take part in the world codesprint and make the event so helpful. So, she studied players, and then found out where she should go in order to improve her strength in coding and some other research.

She chose to do some study after hackerrank world codesprint 9. Because it was so different, the contest started from Friday instead of Saturday, Julia had to go out to play some tennis sports in Saturday day time, she only ended up with around 6 hours to play the contest. She missed the bronze medal and then she spent time to do study of players.

She decided to take some time to study the player one at a time. The facebook is really a great company and Julia also had chances to attend a few of tech events in Vancouver before. So, she likes to take some time to read the article about news feed through a post on linkedin profile.


Study

Study a hackerrank player - a facebook engineer, first study the performance of contest. At least, Julia still covered some basics in her performance compared to a top engineer and a past top researcher. She understands the basics very well. Julia should spend some time to do some research in last advanced algorithm, the player - Gregory Hornby made 10 points out of maximum score 100.

Spend a few minutes to read a graph, picture tells the number:



Julia enjoyed the reading of linkedin profile. She noticed that a few things are in good writing in the profile.

Plan to read about the article - who controls your facebook news feed?

very well-written article - it takes more than 20 minutes to read.
The research of news feed by facebook - It has responded by developing a sort of checks-and-balances system in which every news feed tweak must undergo a battery of tests among different types of audiences, and be judged on a variety of different metrics.

Actionable Items

1. Spend 30 minutes to setup scholar web content for myself - Jianmin Chen, Florida Atlantic University.

No matter how small progress she makes, it all starts from somewhere, humble beginning. All it takes is the time, effort, care, and some determination and a little of love. Research is a fun experience.

Jianmin Chen's scholar.com web page. First time Julia spent less than 10 minutes to setup. The link is here.
