My Facebook Social Network

Last year, Coursera offered a Social Network Analysis course where the instructor is one of the Computational Social Scientist of Facebook, Lada Adamic. Too bad I did not finish this course because it overlapped with another course I was finishing. When this course is offered again, I will definitely complete this since I have to visualize more graphs that deals with the network of textual data using association rule learning.

So here's my Facebook social network. I wanted to mine more information about my friends but after Facebook retired Oauth 1.0, it really restricted a lot of information that you can mine from your friends. I guess that's a good thing because of privacy information concerns. So I can only mine the network map though I found a way to mine my textual posts through the archive feature but I have to build some program, maybe in C++ or Python, to extract the data properly.

The size of each label is based on the mixed degree, meaning our mutual friends. The colors of each line the intensity, the purple being the highest, green is middle and blue is the least.

It is fun to see how my friends (nodes) are clustered together based on their distance of connectivity and how each single friend can be interconnected with two clusters, putting their spot in between as it is the average distance between two clusters.

This is not really a particular big network, consisting of 2,500+ nodes (friends) and 55,000+ edges (how each node is connected). Although with a pretty decent PC running at 8GB RAM, Gephi was already performing slow in running ForceAtlas 2.

See the upper left sub giant network? I probably need to clean up my friends list because they do not make sense. These are my Facebook friends who are closely related to each other by using the recommended friend list of Facebook - a behavioral pattern where a group of men who looks at the stance of your half-naked pictures.

I wonder if there's any platform where I can upload my big network so you can interactively see the nodes and labels.

Stronglifts 5x5 - First Update

Considering that during the last two weeks of December of last year, even how much I avoided any food, since it was the holidays and I was on vacation, there was no point of doing so. So I decided to just eat whatever what was on the table and added some local creatine ethyl ester pills in my supplement list to bulk up some mass. Since my body fat percentage was almost at the borderline of being unhealthy, two months after of no cardio workouts and with all the simple carbohydrates that fueled my workout, I gained 5 kilos of weight and skyrocketed my fat percentage to 22.5%. That frustrated me.

So I looked for a linear progressing exercise program that would make me stronger and revisited my MyFitnessPal diary where I used to log my food intake two years ago. I found Stronglifts 5x5.

I will be keeping a complete workout log, record my progress, food log intake, any measurement, goals etc. The data points are not enough to make some good observation on my progress. I'll definitely post another update after a month... that is as soon as I recover from my lower back pain.

Earlier, I wore my gym belt higher than the usual because it felt more comfortable doing the maneuver as it compresses my upper abdomen but I was so wrong! It did not provide any support to my lower back hence, I felt a very sharp pain on my erector spinae on my fourth, and final set; I failed to complete 5x5. At the first place, I should have started less than 80% of my 1-rep max with this program but of course, I did not. You can even see that I stalled already and deloaded the weights on my second week.

Hopefully after two days of rest, I am recovered without any herniated discs or sciatica.
