• Performing Statistical Analysis with Python

  This is the year I kept digging my old undergraduate notes on Statistics for work. First was my brief attempt wearing the Data Scientist performing ANOVA test to see if there’s correlation between pairs of variables. Then just recently I was tasked to analyze a survey result for a social audit project.

• Reinventing wheels with cheats using Rustlang

  I finally put in some time and effort learning myself a bit of Rust. Though I am still struggling with ownership and lifetimes (which is essentially everything about the language, to be honest), I find it more interesting compared to Golang, which is relatively boring, though being functional (no pun intended). While learning the language, the one thing I came across often is the Option enum, then I remembered that I read something about Monad.

• The Little Pythoner, Part I

  I saw this article from alistapart, which is about Javascript’s prototypal object orientation. So the article mentioned Douglas Crawford, and I was immediately reminded about my struggle in understanding the language itself. Back then I used to also refer to his site for a lot of notes in Javascript. So I went back to have a quick read, and found this article that discusses the similarity between Javascript and Lisp.

• #nand2tetris is fun

  The Nand2Tetris part I at coursera is very much my first completed course. It was so fun to actually work through the material and it feels amazing to know how simple it is to actually build a computer from scratch. While it is simple, it doesn’t mean the course itself is easy though. I was struggling to get the CPU wired up properly that I spent two to three days just to get it working.

• Adding complexity to the bot: threads and processes

  Being new to asyncio, after publishing the previous post on running multiple applications in one event loop, I also cross posted it to the discussion board for feedback. So apparently instead of cramming everything to the same event loop, it would be better if each application run on a separate thread. That makes sense, considering all the code that was written for that.

• Maintaining State with jQuery Event

  Maintaining state in Javascript is not too difficult once you catch the idea. However, as I am not a super brilliant programmer, it takes me some time to find a way to maintain state as YUI Event does in jQuery.

• Understanding potree hierarchy file

  One of my recent tasks involving crawling a lot of geo-tagged data from a given service. The most recent one is crawling files containing a point cloud for a given location. So I began by observing the behavior in the browser. After exporting the list of HTTP requests involved in loading the application, I noticed there are a lot of requests fetching resources with a common rXXX pattern.

• Webmail Checker Alpha for MeeGo Harmattan

  After shifting all my instant messaging accounts to my Nokia N9, I stopped getting email alerts via Adium. Therefore, when I finally remember to check my mailboxes, they are already loaded with exploding amount of mails (mostly junk and newsletter though). I don’t fancy doing my email stuff with my device, and don’t feel like installing a webmail checker to my browser, hence this simple little script is written for my phone.
