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) Linear and Integer Programming: Submitted part 1 and part 2 of Week 2 programming assignment. Both parts are written in Scala and borrow matrix concepts taught in Coding the Matrix course.
2) Coding the Matrix: Statement of Accomplishment with Distinction received today (2013-09-16). The final grade is 99.8% and I forgot I lost 0.2% in week 1 assignment.
3) Linear and Integer Programming: Week 3 videos and Homework 3 released. This week covers simplex method and auxiliary problem.
4) Linear and Integer Programming: Completed Homework 3 (2013-09-20). Use my favorite solver, Octave, to solve question 1, 2, 4 and 5.
5) Metadata: Organizing and Discovering Information: Unit 3 videos released and the topic is how to build a metadata schema using Dublin Core, HTML and XML as examples. Finally, something I can relate to because I have working experience in XML and HTML technologies.
6) Metadata: Organizing and Discovering Information: Completed Homework 3 and earned 15/15 in my third attempt (2013-09-20).
7) Recommender System: Videos of Module 3 were released. I am just going to audit this course because my schedule is packed once again.

EDX:

8) Signed up on CaltechX: CS1156x: Learning From Data . I hope I don’t drop it like I dropped Saas II.  I heard it is an excellent machine learning course (probably as good as Andrew Ng’s machine learning course at Coursera).

MongoDB University:

9) M101JS: MongoDB for Node.js Developers: Week 6 Homework was released in the past Tuesday. I completed the first 4 questions last night and finished the fifth one today (2013-09-20).

Others:

10) Learn to install unbuntu 13.04 on Virtual Box because I need it to complete the last assignment and final exam of M101JS: MongoDB for Node JS Developers.
11) An ex-colleague introduced Vagrant to me and it offers a quick way to set up ubuntu 64-bit in Virtual box.

5) Upgrade to MongoDB 2.4.6 in local machine

EDX:
1) Completed Quiz 1. 5 out of 7, decent score.
2) Did not submit Homework 1. Too busy currently and have to drop the course. I downloaded lecture videos of week 2 and 3 and will watch them when I have time.

Udacity:
