Confirmation bias – the tendency to discredit non-confirmative evidence, or to seek out (actively or subconsciously) primarily confirming evidence – is part of all of us. We all suffer from it, every day. As technologist, we could do better. We should always re-evaluate all the facts and not fall into the traps of our dogma/orthodoxy – what we see or want to see. Rather than reviewing all the facts, we too often hold onto our beliefs. Ask a front-end developer which library/framework should be used for a given project, it’s rarely followed by a question on what the requirements are.…

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.

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.

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.

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.
