The 'Interesting' Moment of Reinventing the Wheel

Level 1: The Shovel vs. Spoon Moment

Imagine you spent all afternoon digging a hole in the sandbox using just a small spoon. You work really hard and finally make a little hole. Then along comes a friend with a big shovel. In one quick go, the shovel digs a perfect hole bigger and better than yours. How would you feel? Probably a bit amazed at how good the shovel is, and a bit silly for not using one from the start. You might think, “Huh, interesting… I did all that work, and you had a tool that could do it so easily!”

In this story, your spoon is like writing your own code from scratch, and the shovel is like a special tool (library) someone else made. The funny feeling is what this meme shows: it’s both wow (because the ready-made tool works so well) and oops (because you realize you didn’t need to struggle so much). It’s a little lesson that using the right tool can save a lot of time. And next time, you’ll remember to check the toy box for a shovel before you start digging with a spoon! 🥄🔍🏗

Level 2: Discovering Dependencies

Let’s break down what’s happening in this meme. A third-party library is a chunk of code written by someone else (often open-source) that you can add to your project to provide certain functionality. For example, if you need to generate PDF files in your app, instead of writing all the PDF logic yourself, you might install a library like pdfkit or FPDF. In the scenario shown, the developer spent four hours crafting a hand-rolled function – meaning they wrote a custom solution from scratch – for a problem, only to later find a library that already solves it better. The reaction in the cartoon is “Interesting”, which here is a dry, amused way of saying “Well, isn’t that something…” (imagine a developer smirking at their screen).

The top text sets up the context: “when I find a library that does what I spent 4 hours coding but better in every way:”. This is a common feeling in software development. You toil on code for hours, then realize someone else has published a ready-made solution. It’s like doing a complicated puzzle and then finding the answer key after you finish. The bottom image shows Skeletor, the cartoon villain from He-Man, looking thoughtful and saying "Interesting". This image is a popular meme format used to express surprise or ironic interest. Here it’s used to represent the developer’s face upon this discovery. Skeletor is ironically perfect because he’s a dramatic character – seeing him say “Interesting” exaggerates the “Oh wow…” reaction a developer might have in this situation.

Now, why would a library do a better job than code you wrote yourself? Think of it this way: the library might be created by experts and refined over time by many users. It probably covers edge cases you didn’t think of and is optimized for performance. This relates to Code Reuse – a best practice of reusing existing solutions so you don’t repeat work unnecessarily. There’s a famous saying in programming: “Don’t reinvent the wheel.” The wheel in this context means a solution that already exists. If someone else has built a solid, round wheel (the library), there’s usually no need for you to build a new one out of wood and stone (your quick custom code). When you reinvent the wheel, you spend time and effort to create something that already exists, often not as well as the existing one.

Using third-party code is done through dependency management. This is how developers fetch and manage libraries in their projects. For example, in JavaScript you might run npm install some-library to add a dependency, or in Python use pip install library-name. These package managers handle downloading the library and making it available in your code. Relying on dependencies can massively speed up development – why spend hours or days coding something that you can get instantly? However, it has trade-offs: adding too many libraries (sometimes jokingly called “dependency hell”) can make your project heavier and introduce compatibility or security issues. It’s a balance.

The meme also nods to something called Not Invented Here syndrome (NIH). This is when individuals or companies avoid using external solutions just because they weren’t developed in-house. It’s like saying “If we didn’t invent it, it’s not good enough.” This mindset can lead to duplicating a lot of work. In contrast, good developers learn to appreciate the giant ecosystem of open-source. There’s no shame in using a well-made library. In fact, discovering a great library is often exciting – it’s like finding a power-up in a video game that suddenly makes you stronger or faster at solving a problem! But in the moment of this meme, the excitement is mixed with facepalm: the developer is amused that the library is so good, and a bit regretful they didn’t find it earlier.

For a junior developer, this is a rite-of-passage moment. Imagine you write a sorting function to sort a list of numbers because you’re not aware your programming language has one built-in or available via a library. Maybe your function works on basic tests but fails on some tricky cases or is slower on large inputs. Then you learn about the standard sort function or a utility library that does it in one line, handling all sorts of cases and large inputs efficiently. You’d probably think, “Oh, interesting… they already solved this!” and chuckle at the situation.

For example, check out this Python snippet of a hand-written sort versus using the built-in sorted function:

def bubble_sort(arr):
    # A simple (inefficient) sorting algorithm
    for i in range(len(arr)):
        for j in range(0, len(arr) - i - 1):
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr

print(bubble_sort([5, 2, 8, 1, 3]))  # Our hand-rolled sort

print(sorted([5, 2, 8, 1, 3]))      # Using Python's built-in Timsort

The custom bubble_sort might take you a while to write and debug, and it does sort the list (outputting [1, 2, 3, 5, 8]), but it’s much slower for big lists and doesn’t handle complex data types. The built-in sorted() is highly optimized (Timsort algorithm in Python, which is faster and more robust). This little example shows why a library or built-in function can outshine your code – it’s better tested and optimized “in every way.” The developer in the meme likely had a similar experience: after hours of effort, seeing a library do more in seconds leaves them saying “Interesting.”

In short, this meme teaches a lesson: Always check if there’s an existing solution before coding from scratch. It’s a happy discovery when you find the perfect library, even if it makes your past 4 hours of work feel redundant. You’ve gained knowledge (and perhaps a chuckle), and next time you’ll remember to reuse instead of reinvent. The good news is you’re not alone – every developer has this “Oops, someone already built this” moment, and it actually helps you grow. It’s all part of the developer experience!

Level 3: Wheel Reinvention Regrets

In the top caption, a frustrated dev admits: “I spent 4 hours coding something, only to find a library that does it better in every way.” The image of Skeletor (the cackling villain from 1980s He-Man) looking oddly contemplative with the subtitle “Interesting” perfectly captures that mix of awe and regret. This scenario is painfully familiar to experienced developers. We’ve all reimplemented a feature from scratch – hand-rolled code born of caffeine and optimism – only to later stumble upon a polished third-party library that accomplishes the same task effortlessly. The humor here is that humbling moment of realization: our clever DIY solution was actually a reinvention of an existing wheel, and a wobbly wheel at that! 🤦‍♂️

From a senior engineer’s perspective, this hits on the classic build vs. buy dilemma (or in open-source terms, build vs. download). Seasoned devs often weigh: Should I implement this functionality myself, or leverage an existing dependency? The meme nails the irony of choosing “build” and then discovering a far superior “buy.” Why is the library “better in every way”? Likely because it’s the product of many contributors, years of refinement, and countless real-world tests. That one-line import has optimizations and edge-case handling our quick script didn’t even consider. It’s a punch to the ego (ouch!), but also a learning moment. The DeveloperExperience (DX) lesson: next time, check the ecosystem before burning hours on a custom solution.

This touches on the notorious Not Invented Here (NIH) syndrome – an inclination to distrust external solutions and write our own. Many of us have a stubborn streak of “I can code this myself!”. Sometimes it’s pride, other times we simply didn’t know a good library existed. The meme’s laugh-factor comes from hindsight: had we searched first, we’d have saved time. It’s programmer regret wrapped in humor. The Skeletor frame adds a layer of playful exaggeration; even a cartoon villain is fascinated by how an open-source project outshines our DIY attempt. In reality, discovering a great third-party library can feel like both a victory (“Yay, I found the solution!”) and a facepalm (“Why did I reinvent the wheel?”).

Let’s be honest – writing code from scratch has some perks. You get full control and perhaps a deeper understanding of the problem. But more often than not, it means re-solving problems that experts have already solved better. A mature library might be more efficient (using a faster algorithm), more robust (handling weird inputs), and more maintainable (well-documented, community-supported). Meanwhile, our hand-rolled version probably has hidden bugs and lacks features. As a senior dev, you chuckle because you’ve been there: maybe you coded a mini JSON parser one weekend, only to find out about json libraries that handle 100+ edge cases. Or you built a custom caching layer, then discovered Redis does it faster and safer. The meme speaks to those battle scars and the unspoken agreement that the best code is often the code you don’t write.

It also highlights dependency management realities. Modern projects pull in dozens of libraries via package managers (npm, pip, Maven, etc.) because nobody wants to reinvent common functionality. The ecosystem is so rich that there’s likely a package for everything – sometimes even for trivial tasks (remember the infamous left-pad fiasco, where a 11-line string padding library broke the internet?). The punchline: our industry rewards code reuse. Using a well-vetted library is usually a smart shortcut, but it feels ironic when you discover it after doing all the hard work yourself. In summary, this meme resonates with developers because it humorously captures a universal experience: the humbling, interesting moment when we realize our sweat and code have been outclassed by an open-source gem available with a simple install. As Skeletor might say after seeing our reaction: “Until next time… use the library, you fools!” 😄
