Confirmation Bias in Tech: Why We Choose Solutions Before We Understand Problems Confirmation bias, the tendency to seek out evidence that supports what we already believe and dismiss anything that challenges it, is part of being human. We all carry it. We all act on it, often without realizing it. But as technologists, we like to think of ourselves as rational, evidence-driven people. We deal in logic, in systems, in reproducible outcomes. Surely we’re above the petty cognitive shortcuts that trip up everyone else. We are not. And the consequences of pretending otherwise show up in production codebases every single…

Unless you’ve abstained from social networks, you’re probably heard of Wordle or have seen blocks of green, black, and yellow on your social feed. I have to admit, I’ve been caught up on the riptide – even google has acknowledged the popularity of it I tend to stay away from mainstream fad – especially those on social media platforms. I did, however, read the article on New York Times – who later purchased it for 7-figures. Eventually, I gave in and played to see what the craze was about. To my surprise, I was instantly hooked. I was surprised by…
It’s been a while since I posted an entry – just go ahead and look at the date on my prior post. I don’t even know if blogging is a thing anymore in the world of TikTok. Granted, given how vastness and complex technology space is, I don’t think anyone can do justice on a short video. Look, it’s not like this is my New Year’s resolution or anything like that. Let’s see if I can try to post at least once a month. And yes, I get credit for this post towards January.
In my original Tetris code base, I started out with a simple RotationController class. As I recall, this was a trivial class with a single shape. However, as more shapes were added, it quickly became unwieldy. Looking back at this code, I want to cringe at my lack of discipline in following proper design principles. On the bright side, I have something to blog about. Chain of Responsibility The chain of responsibility design pattern is known as a behavioral pattern consisting of client objects and a series of handler objects. It provides more than one object the opportunity to handle a request by…
I’ve been planning to write some tutorials on design patterns. I just need to find some time and my day job at the corporate world has kept me busy. I plan to use this code base from a java tetris application I wrote a while back. I’ve done some clean ups – who’s not embarrassed by their old code. Don’t worry, I haven’t completely cleaned it up. After all, the plan is to write tutorials on design patterns that would help improve this code. My first topic, when I do get some time, will be Chain of Responsibility.
