Beautiful Kernel Functions and How to See Them

If you know the 'shape' or pattern of the given dataset, you can use the right kernel function when training a GP model. This is where domain knowledge of a given dataset can be useful. One fun thing I love about kernels is that you can add or multiply them to form composites.

My Dilemma on Venture Creation

Here's my challenge: I do not have ideas that could produce a venture like the one I described above. While I have ideas for things that could make money, they are either not exciting to me or could easily be replicated.

Why Dance Monkey matters

What is more interesting is that the audience has a circular relationship with the performer. Today's audience are tomorrows performance, so they watch not only to be entertained, but to learn how to perform.

Designing Interfaces for Complex Ideas

There is a lot of upside in designing good interfaces for ideas, and I think this is particularly important if your work involves producing new knowledge or tools. A well designed interface reduces the barrier to interacting with ideas.

Educators Should Think like Hackers

Both the Black and White Hat Hackers share the mindset of adaptability, understanding systems, identifying vulnerabilities, and creating countermeasures. In the world of security, if a method is revealed to be vulnerable, there’s usually a rally for better and more secure methods.

It is this sort of thing

You see, I am not so different from the homeless man on the sidewalk. Our core needs are the same, and just like me he has dreams and hope for future. Our stories converge on this basis. It is people who decide hierarchies and structures that have an undertone of inequity.

Thirteen questions that have kept me up at night

What are important and interesting problems that we can't even begin to tackle because we do not have the right tools to navigate them?

Dear Ifeoluwa, or the anatomy of sad news.

I live with your dreams and desires, at least the ones you shared with me. Your plan to pursue a masters degree. The business ideas you had and the other tiny things you looked forward to. Top of that list is the fun vacation we planned to take this year.

There Shouldn't be an AI Race

We will also see progress as AI tools are developed and deployed at scale. It is all inspiring, but who does it help in the long run if a certain nation wins this "race"?

There's art in creating software that doesn't scale

You create software that is local, fun, private, and free of commercial exploitation. Software can be like "a home-cooked meal" and something inherently personal.

Less Noise

What I envision for good digital spaces are ones that allow users to curate their experience and are not entirely run by algorithms. Creators should also strive to widen the signal-noise gap.

Goodhart's Law and Designing Good Systems

There's a saying that 'the purpose of a system is what it does.' While many people might agree with that statement, there are certain cases where we have desired outcomes, and it would be unwise to settle for emergent properties that are observed.

In the Fading Light of Prologue

We all live through our prologues, but we never know when the ride ends and turns into an epilogue. Just as John Green wrote, "You die in the middle of your life, in the middle of a sentence."

Beyond the Wall's Gaze

From that vantage point, I had an unintimidating view of Zuma Rock, and I would go up there to watch the sunset in the evening. On idle days, I whiled away the hours trying to synchronize my heartbeat with the pulsing red light atop a radio mast near our apartment

Personal life is a playground for solving optimization problems

It is uncommon to discuss optimization in terms of our daily lives; instead, it is typically reserved for contexts involving large-scale operations, supply chains, technology, or business procedures.

Involuntary Chants

I've been trying to diagnose a phenomenon that I noticed in myself for a few months. I don't know what to call it, but I'll go with "Involuntary Chants." That might not be a fitting name, but I'll describe it using two instances.

Lessons from Ajegunle-style music in the 90’s

Although their songs had different lyrics, they mostly told a similar Nigerian story, which is also similar to what Fela narrated in his song

Musings of a failed writer

Sometimes I wonder if my high standards for good writing make me give up from the jump because I don’t trust myself to commit to a piece until it’s good enough for my taste.

Toolbox for Serving and Maintaining Machine Learning Models in Production

There are a couple of tools that market themselves as all-in-one MLOps kits. I’ve not used most of them because they are sometimes expensive proprietary software, but they might be ideal for teams looking for tools that are easier to set up and manage.

Dear Anthony, or Can I relive lost times?

There'll never be any new Michael Jackson songs, Jackie Chan will never make a new movie, and the OG online forums no longer exist. You get the point; life is getting bland, and we get our daily high from the random reports of technological progress.

I have a problem with color

In recent months, I've been thinking a lot about the history of the use of color to refer to people. Why we do it and how it began. As a current human, you probably know that races are primarily divided into black, white, and brown.

The Dog's True Fate

"The patient dog eats the fattest bone". Nearly every child who grew up in Nigeria knows that quote; it was told and repeated to us everywhere: at home, in schools, in markets, and in religious places.

Against dating apps

It could be the compression of complex human personalities into pictures and words that makes me hate them, or the fact that people turn themselves into filters because of the sheer magnitude of choices they've unlocked, but my contempt for dating apps extends beyond that.

Annie Ernaux Truly Deserved the Nobel Prize

The importance of Annie winning the Nobel prize is that great work was brought into the limelight for many of us to notice.

Simulating Nigeria

Over the last few weeks, I've been doing a lot of things to make me feel at home, whether it's through the type of food I eat, the music I listen to, or the movies I see.
