Do You Have A "Mayo" Problem?


Let me explain what the "mayo" problem is with a story. You are getting ready to make a sandwich and you start piling on your ingredients. You have the bread, lettuce, tomatoes, cold cuts, salt and pepper. And you think to yourself, the one ingredient that would finish it off is the mayo. You have some choices here. You can either grab the jar of mayo out of the fridge or you can grab the olive oil, egg yolk, mustard, and your lemon juice.


You grab your blender and you start mixing up all of the ingredients and you make this absolutely beautiful mayo and put it on your sandwich. It sounds like the perfect scenario


In all honesty, you could have just used the jar of mayo.


The reason is because you spent a lot of time pulling those ingredients together when the actually goal was to make a sandwich, not mayonnaise. Don't ignore the tools that make your programming journey easier because your job is to deliver results, not mayo.

Are You A Vibe Coder?

There has never been a better time to bring your ideas to life when it comes to coding because current technology has ushered in vibe coding


You can literally create applications using LLM (Large Language Models) to code out ideas and then make improvements based on those ideas. The easiest tool to mention is ChatGPT and I dont think programmers are even aware of the capabilities of the tool and what it can do to help them in programming.


My personal opinion is that vibe coding works even better if you already know how to code. There are concepts in the programming world that if you understand can be applied over and over. You can spot the gaps in results that are returned by ChatGPT and be able to accurately define exactly what it is you want your solution to do.


Here are the main solutions that I found and when I would recommend using them:



  • ChatGPT - use this tool to get the plain written solution of what you need done.

  • Claude Code - This AI tool is a beast. It produces high level programming code. It will assist you in integrating the code and helping you to get it to work.

  • Famous AI - I tried it but it was a little buggy for me. If anyone else has had a better experience using this solution, I would love to hear about it.

  • Cursor AI - This one is definitely going to get your attention especially since the tool walks you through and makes updates as you are coding.


Here are my recommendations for using these tools:


Whenever you are making a request for assistance and you try to apply the solution and it doesn't work or produces an error. Take the feedback you received and put it back into the AI solution. It will work with you until you arrive at a final solutions.


Don't be concerned about the number of times you are putting errors or feedback back into the AI solution, it doesn't care. It will continue to help until the best of its ability


Always look for opportunities to do a deep dive. If you come across a phrase or comment that you don't understand and was recommended, take your focus away from the solution you are trying to create and now focus on that specific feedback you received. You leveling up on that subject area will improve your programming overall.


Don't put all the burden on AI, always look for opportunities to improve your programming. The better you get at programming, the better your solutions get.

What Does It Take To Be A Good Programmer

Becoming a good programmer requires more than just the ability to write code. It involves a combination of technical skill, problem-solving ability, persistence, creativity, and effective communication. While programming languages and frameworks change over time, the foundational traits of a good programmer remain constant.



First and foremost, a good programmer must have strong problem-solving skills. Programming is ultimately about finding solutions to problems—whether it's automating a task, creating a user interface, or building an entire system. Good programmers approach problems methodically. They break down complex challenges into manageable parts, analyze potential solutions, and select the most efficient and maintainable approach. This analytical mindset is the core of effective software development.



Technical proficiency is equally important. A good programmer is well-versed in one or more programming languages and understands the underlying principles of computer science such as data structures, algorithms, memory management, and object-oriented design. However, the best programmers don’t just memorize syntax—they understand how to apply language features effectively and when to adopt different paradigms such as functional or procedural programming.



Continuous learning is another hallmark of great programmers. The tech industry evolves rapidly, with new libraries, tools, and methodologies emerging all the time. A good programmer embraces this change, stays current with industry trends, and is eager to learn and adapt. Whether through formal education, online courses, reading documentation, or contributing to open-source projects, they never stop improving.



Persistence and patience are also crucial. Programming often involves trial and error. Bugs can be elusive, and debugging can be time-consuming. A good programmer doesn’t get discouraged when code doesn’t work the first time. Instead, they investigate, test, and refine until the issue is resolved. This mindset of resilience is what enables programmers to tackle increasingly complex problems with confidence.



Creativity might not always be associated with programming, but it plays a vital role. Writing clean, efficient, and elegant code is a creative act. So is designing intuitive user experiences or architecting scalable systems. Good programmers think outside the box and are open to innovative solutions that others might overlook.



Communication and collaboration are essential as well. Rarely do programmers work in isolation. They often collaborate with other developers, designers, project managers, and clients. A good programmer can clearly explain technical concepts to non-technical audiences, write understandable documentation, and contribute effectively in team environments. Writing readable code with meaningful comments is also part of this communication skill set.



Lastly, a good programmer practices discipline. This means following coding standards, writing tests, maintaining version control, and thoroughly reviewing code. These habits ensure that software is reliable, maintainable, and scalable over time. A disciplined approach builds trust among teammates and contributes to the long-term success of a project.



Becoming a good programmer involves far more than just coding ability. It requires a commitment to learning, a methodical and creative mindset, strong communication, and the perseverance to overcome obstacles. By cultivating these traits, anyone with the passion and dedication can grow into a truly exceptional programmer.

What Are The Benefits Of Dynamic Coding?

Dynamic coding, often referred to as dynamic programming or dynamic scripting, is a style of programming where code can adapt or change at runtime. This can be achieved through interpreted languages like Python, JavaScript, or PHP, which allow for flexible structures, on-the-fly code execution, and runtime data manipulation. Dynamic coding stands in contrast to static coding, where the structure and type of data are rigidly defined during compile time. The benefits of dynamic coding are numerous, especially in today’s fast-paced software development environments.

1. Flexibility and Adaptability

Dynamic coding enables developers to write flexible programs that can handle a wide variety of data types and structures without extensive boilerplate code. For instance, a function in Python can accept multiple data types without the need for method overloading. This flexibility is particularly useful in web development, data analysis, and machine learning, where input data may vary in format or size. Developers can also modify behavior at runtime, such as dynamically loading modules or changing object attributes on the fly.

2. Faster Prototyping

Dynamic languages significantly accelerate the prototyping phase of development. Since developers do not need to compile code before running it, they can quickly test ideas, adjust logic, and iterate on features without the long feedback loops associated with compiled languages. This allows teams to experiment and innovate rapidly, which is especially important in startups or research environments where time-to-market and innovation are crucial.

3. Concise and Readable Code

Dynamic coding often results in shorter, more readable code. The reduced need for explicit type declarations and structural definitions simplifies syntax, making it easier to understand and maintain. Languages like Python and Ruby are renowned for their clean, human-readable syntax, which lowers the barrier to entry for new programmers and enhances collaboration within teams.

4. Enhanced Runtime Capabilities

Dynamic programming enables advanced features such as reflection, introspection, and metaprogramming. These allow developers to examine and modify program structure and behavior during execution. For example, in Python, developers can inspect objects, access metadata, or dynamically create functions. These capabilities are especially valuable in frameworks, plug-in architectures, or systems that require runtime configuration.

5. Better Integration and Interoperability

Dynamic coding facilitates integration with other systems, APIs, or platforms. Web technologies often involve dynamically handling data from APIs or user inputs, where static typing would be cumbersome. Moreover, dynamic languages typically have rich ecosystems and libraries that simplify tasks such as data parsing, UI generation, and automation, reducing development time and complexity.

Conclusion

Dynamic coding empowers developers with the tools to build flexible, adaptive, and efficient software quickly. It reduces overhead in early development, enhances readability, and provides powerful runtime capabilities. While it may introduce certain trade-offs in performance and type safety, these are often outweighed by the gains in productivity, especially when managed with best practices such as testing and type hinting. As technology continues to evolve, the benefits of dynamic coding will remain a valuable asset in the developer's toolkit.
