    Coursera:

    1) Metadata: Organizing and Discovering Information: Submitted Homework 5.
    2) Metadata: Organizing and Discovering Information: Videos of week 6 released.
    3) Linear and Integer Programming: Week 6 videos released.
    4) Linear and Integer Programming: Finished watching week 5 video lectures and starting to work on homework 5. This assignment is consisted of 3 multiple choice questions and 1 programming question that needs to solve by a solver and my favorite solver is Octave.
    5) Human Computer Interaction course started on Tuesday. I downloaded video lectures of the first two weeks to my android smartphone and will watch them whenever I have time.
    6) Introduction to Recommender System: As predicted earlier, I was too lazy to write up homework assignment 3 and did not turn it in. This action costs me 6 marks and hurts my chance of earning Certificate of Completion. I better start homework assignment 4 early and not miss future homework assignments.

    EDX:

    7) CS1156: Learning From Data: Submitted Homework 1 and the total score is 9/10. The final grade does not tell the whole story because I worked really hard to get the PLA code to work correctly in Python and LionSolver. The questions asked students to calculate disagreement that is the P(f != g); I took advice from class forum and calculated the probability by Monte Carlo method. If Homework 2 is any harder, I should look for online references and machine learning references at nearby public library. Did I mention it is a first-year undergraduate course? (Sigh)

    MongoDB University:

    8) M101JS: MongoDB for Node.js Developers: Certification of Completion issued today (2013-10-09) Thanks Andrew and the staff of MongoDB for teaching these courses for free. Now, I understand why MongoDB gains so much hype in IT industry and it is really the next big thing.

    Programming:

    9) Attended week 3 of IOS Course.
    10) Attended week 2 of Windows 8 App Development Course.

    Coursera:

    1) Metadata: Organizing and Discovering Information: Submitted Homework 4.
    2) Metadata: Organizing and Discovering Information: Video of week 5 released.
    3) Linear and Integer Programming: Submitted week 4 programming assignment. The level of difficulty keeps increasing in each programming assignment. Longer time is spent to augment code, debug program logic, run test cases and verify results. I pray to God that I have the strength and determination to go through the rigid schedule and materials in the next five weeks.
    4) Linear and Integer Programming: Week 5 videos released but I still need to watch week 4 video lectures and attempt week 4 assignment. Damn, I am falling behind.
    5) Linear and Integer Programming: Watched all week 4 video lectures and submitted homework assignment. The assignment is manageable because it is consisted of four short questions.

    EDX:

    6) CS1156: Learning From Data started today and I already face issue. The tool, LionSolver, that is useful to solving homework assignments does not run on Linux platform. As a result, I have to install Wine on my ubuntu machine and run LionSolver in it. Thankfully, Oct 1 is public holiday in HK and I will use the extra free time to install software and watch some videos
    7) CS1156: Week 1 already has two video lectures that play in the duration of 3 hours and 15 minutes. Homework has 10 multi choice questions that look difficult. I attempted 4 questions and got 3 right (sweat in my palms) and 6 to go.

    MongoDB University:

    7) M101JS: MongoDB for Node.js Developers: 10/10 in final exam and 100% overall grade.
    8) M101J: MongoDB for Java Developers: Certification of Completion issued today (2013-10-03).

    Coursera:

    1) MetaData: Organizing and Discovering Information: Must watch week 4 videos over the weekend because homework is due next Thursday (Oct 3).

    MongoDB University:

    2) M101JS: MongoDB for Node JS Developers: Answered all questions in the exam finally. Question 7 is the hardest in my mind because I spent three days to get the correct answer. Eventually, I wrote two versions for this question: pure Javascript solution and Node JS solution. Both solutions yield the same answer, so I am confident my NodeJS implementation is correct. I am more comfortable of MongoDB than Node JS in this course, the asynchronous feature of Node JS had me scratching my head when working on homework problems and exam questions. Even though this course ended, it is not the end of my Node JS journey, it is just the beginning.

    Others:
    3) Installed Ubuntu OS on my laptop last night and insanely using “apt-get install” command to install development tools and packages(git, python, octave and many more).

    Coursera:

    1) Linear and Integer Programming: Week 4 videos and Homework 4 released.
    2) Recommender System: Submitted Written Assignment 2 and Programming Assignment 1. Written Assignment 1 was peer-graded and surprisingly my grade is 6/6.
    3) Recommender System: Watching lecture videos of module 3 and I have absolutely no clue how to tackle written assignment 3 and programming assignment 2. Module 3 is about content-based recommender that talks about user preferences, attributes and items. As usual, I have to watch the videos repeatedly until the concepts become clear to me.
    4) Metadata: Organizing and Discovering Information: Unit 4 videos released and the topic is Alphabet Soup (What the heck does that mean?). I find this course boring and may consider to give it up to concentrate on current courses and upcoming machine learning course.

    MongoDB University:

    5) M101J: MongoDB for Java Developers: Final exam was autograded today (2013-09-24) and my fear became reality, I got question 5 wrong again (this is starting to get on my nerve). I better watch the answer video before I attempt M101JS final examination before deadline.
    6) M101JS: MongoDB for Node.js Developers: Week 7 videos and final exam released today (2013-09-24).
