There is No Such Thing as Maturity…
There is no such thing as maturity. There is instead an ever-evolving process of maturing. Because when there is a maturity, there is a conclusion and a cessation. That’s the end. That’s when the coffin is closed. – Bruce Lee Read More…

Guava: FluentIterable vs Collections2
PROBLEM Guava’s Collections2 is great when dealing with collections, but it quickly becomes rather clumsy and messy when we try to combine multiple actions together. For example, say we have userIds, which is a collection of user IDs. For each user ID, we want to retrieve the Employee object and add it into an immutable… Read More…

Combining and Minifying JavaScript Files with Google Closure Compiler
GOAL The goal is to combine and minify several JS files into one JS file in the right order. PROBLEM Let’s assume we have the following directory structure with three JS files. Directory Structure appdev.js appdev.blackcow.js appdev.whitesheep.js SOLUTION To pull this off, we will leverage Google Closure Compiler. There are multiple ways to use this… Read More…

IntelliJ: Overriding Log4J Configuration Globally for JUnit
PROBLEM Most of the time, we may have several Log4J configurations depending on the environments, for example:- Since log4j.xml and log4j2.xml are the default configuration files for Log4J and Log4J2, these configurations will always be used unless we override the configuration file path. In another word, if we don’t override the configuration file path and… Read More…

Java: Promoting Testability by Having Enum Implementing an Interface
OVERVIEW This post illustrates how we can easily write a better test case without polluting our production code with non-production code by performing a minor refactoring to the production code. PROBLEM Let’s assume we have a simple Data Reader that reads all the lines of a given algorithm data file and returns them:- This API… Read More…
About Author
This author has 20+ years of experience in software engineering and cloud engineering. In an industry where knowledge becomes obsolete in the next three months, he learns anything that crosses his path indiscriminately. He floats from one technology to another like a moth and stings the problem sets like a mosquito. This author codes Java while drinking Espresso and writes Spock specifications while listening to Groovy beats. He masters Google Cloud Platform just like how he masters the art of predicting the movement of dark clouds over his backyard, where 60% of the time, he is right every time.
This author suffers from the Dunning-Kruger effect, where he overestimates his competence and underestimates his ignorance. Technology buzzwords never faze him, for he does not know enough to be afraid of in the first place. GCP, GCS, GCR, GKE, GWT… everything sounds the same to him. He never fears acronyms, synonyms, or antonyms, for he has ChatGPT in his back pocket. This author is a jack of all trades but a master of none. He writes like he knows all the answers, yet he googles for better solutions from elsewhere. He fakes it until he makes it; if he doesn’t, that’s okay because he has the attention span of a squirrel. The blog posts are his buried walnuts, in case he needs them one day.
In conclusion, this author is full of something. He apologizes in advance if you are trying to solve your company’s real problems with his shitty solutions. There, he has successfully written paragraphs of nonsense because every professional blogging website needs a section about the author, with a too-cool-to-smile portrait staring sideways into the abyss.
