According to a 2019 life expectancy report, the average lifespan of the whole world is 72.6 years, but for Japan, it is 84.6 years. With more than 29% of its population over the age of 65, the Land of the Rising Sun is consistently recognized for its big community of healthy elders. On December 28, 2012, Jiroemon Kimura became the oldest verified male in history — he lived for 116 years and 54 days before dying from natural causes.

What’s the Japanese secret to maintaining good health for so many years? In Japan, it is no secret. In fact, everyone…


How I screwed things up to end up being on the right path

It’s been quite an adventure since the dawn of my big data engineer career. I started out differently compared to a typical path. Being a fresh graduate, I possessed nothing more than an academic research background and an enthusiastic attitude. But that wasn’t enough, and I’ve had a couple of rough years.

In life, things turn out to be much simpler when you know what to avoid. I didn’t have that luck, but I’ve learned over my mistakes. There’s a saying in my culture that goes: “You don’t get to choose your job, but it picks you instead”. It was…


Know your data better than you know yourself

Either you are a data scientist, a data engineer, or someone enthusiastic about data, understanding your data is one thing you don’t want to overlook. We usually regard data as numbers, texts, or images, but data is more than that.

We should consider data as an independent entity. Data can make self-introduction, tell stories, and visualize trends. To reach those outcomes, you must understand your data first. Not only about how it was formed or its origin, but how it’ll change over time and its usability. Some of this information is what we call metadata.

Why is metadata so important…


The never-ending fight to cease bad data

Bad data is expensive

According to an IBM study, bad data cost the United States 3.1 trillion dollars in 2016. To picture how big that money is, it’s twice Canada’s GDP in the very same year.

1. Organizations believe poor data quality to be responsible for an average of $15 million per year in losses - Gartner research2. 60% of data scientists admit that they spend most of their time cleaning and organizing data - CrowdFlower3. It costs 10 times as much to complete a unit of work when the input data are defective as it does when they are perfect …


Great lessons from big tech companies

The world of technology moves fast, and nobody wants to be left behind. In software and data landscape, we need to stay tuned with all the new libraries and frameworks. We, software engineers, want to be close to the state-of-the-art technologies. Fortunately, there are places where experienced, competent engineers are willing to give back to the community.

A piece of knowledge sharing is a piece of knowledge gaining. Big tech companies understand how to handle various technical issues. These range from software development, database architectures to user experience optimization, or even how to create seamless applications. …


Not all failures are equal.

“Success is not final, failure is not fatal; It is the courage to continue that counts.” — Winston Churchill

Steve Jobs got kicked out of his own company. He came back almost 15 years later to save his company from bankruptcy. His effort made Apple one of the most successful companies in the world.

In 1993, J.K. Rowling admitted that she had failed at everything she has attempted to do. Two years later, she finished her first manuscript of the Harry Potter series. Many major publishers rejected her, but she persisted in completing the series. …


We ain’t doing the same thing

Engineering is an essential element of all corporations. Without it, companies are unable to create, maintain, and upgrade their products. Technology enterprises rely on their engineering department to survive in a competitive world.

Even so, not all engineers perform the same set of tasks. In heavy technology-based companies, software engineers are one of the most critical resources. They build programs, create software, and maintain the functionality of the systems. Many other career paths diverge from software engineering. They specialize in a particular subject.

In the data landscape, corporations face a tremendous growth in data amount. We need someone to step…


A curious mind never knows its limit

I have fulfilled a father’s duty in explaining Big Data to my six-year-old. Even so, I sensed a visible dissatisfaction with the answer.

I wasn’t sure of the reason. Either I upset my child breaking down its favorite LEGO set or my interpretation wasn’t educative enough. Anyway, I had to come up with another plan.

My child has no doubt grasped one thing or two about Big Data, but Big Data is more than that. I recalled my journey on becoming a big data engineer. I thought of how I perceived each of its core concepts in the first place…


To decide on the best words is an endless fight

Photo by Daniel Cheung on Unsplash

I struggle at all times to put pen to paper in a language I didn’t grow up with. Once in a while, my writing sounds unnatural, baffling, and ludicrous to native speakers.

A myriad of aspiring writers prefers to compose their articles in English to approach a broader set of readers. I choose to pen down my thoughts in English plainly because it’s a beautiful language.

Language is the voice of culture.

Being native in a language divergent from English restricts you in some way to perceiving the natives’ mindset. …


And bad codes are full of them

I urge you to take a good look at the two following pieces of code

Which one do you prefer? At a glance, the former seems to have done a great job describing explicitly every single one of its operations. However, these instructions are utterly redundant and obsolete. They solely add another layer of confusion to the reader. Bad comments are excuses for poorly named variables and inadequate programming skills.

Here’s what your co-workers will think about while evaluating the above code if you are the one who wrote it
