Part of my RelevantXKCD project writeup After I wrapped a simple Django server and posted it on Reddit in the subreddit /r/xkcd, I got some great feedback! For the Model As /u/drcopus helpfully enlightened me, I should’ve done data augmentation on the original training set. I could’ve...
Signatures are truly a work of art. As they mature through age, they become more flowing, graceful, and elegant. I remember the days during my childhood, when, after meticulously writing my name in cursive, I would broadly proclaim: “Look at this beautiful signature.” It was a long...
Have you ever noticed how mobile sites are taking longer and longer to load? When I want read the news on the LA Times, they first load all the fancy animations (while I’m staring at a white page), and then finally the article appears. I understand why...
So I embarked on a machine learning quest as a senior project. With all these advances in AI, I wanted to have some fun myself :P. You can view it here. I was inspired by Dan Zhang and Megan Ruthven’s Relevant XKCD finder. They used ExplainXKCD to populate...
Replacing an iPad Air screen turned out to be much simpler than what iFixit made it seem to be (43 steps!) and probably the most accomplished thing I did all winter break. However it did take a long time (maybe because I was just being to precautious)....
AP Tests are supposed to get you ahead in college, and in some cases, it does. However, overloading on AP credit doesn’t really help you as much: be wise in what you take, and if you decide to take it, study! Going to college I was surprised...
Ruby Wrappers: RMagick, RTesseract (image manipulation and image recognition respectively) You can Google how to install those gems. Here was an example page of the dictionary. The shorthand translation was pretty much adjacent to the English word.

Sometimes it is unnecessary to load images in my selenium scripts. It takes time for the images (especially large ones) to load and messes up my sleep functions. Here’s how to prevent it from loading. There are more options and it’s listed in the All Profile Options...
How I loaded the files in python
Part of this entire writeup Goal Find a model to accurately predict a relevant XKCD given multiple words (a reddit comment). This essentially gave me a bunch of positively single-labeled data since each comment usually only had one “relevant XKCD” sub-comment attached. Example: Searching “Python” would return...
So I embarked on a machine learning quest. Here are my notes on how I obtained the data. My first attempt a few months ago was to download the entire Reddit Corpus (in CSV form) and manually parse the comments. However, it soon became clear the my...
This article requires knowledge of Ruby, the concept of webscraping, and HTML. Make sure you have Ruby installed (use RVM if you don’t have it yet) — I’m using 2.3.1 right now. If you want a reference sheet, I’m in the process of writing one :P. Link...
My programming environment is quite nice on a chromebook. Although my chromebook is not the top of the line, ASUS C201 11.6 Inch, it does allow me to push some quick updates and do a bit of local testing for debugging. Note: When I compile and run,...
