Multilingual Programmers

One of the biggest difficulties in the computer programming world today is the sheer number of languages out there to use for application development. Which language should you learn? The reality is, that’s the wrong question. I recently spoke with a developer who indicated that he only knew C# – he was not comfortable with Python or any other language. For the professional developer, this it not an acceptable answer. In today’s world of programming, you can no longer get by knowing only a single language. For example, while the bulk of the code in a Java web application will be in Java, the front-end will require JavaScript and HTML. Build scripts may be written in Groovy or XML, and Shell scripts may be required for build automation. This is not unique to Java applications – just about any application will require some knowledge of other languages.

How do you pick which languages to learn? At a minimum, every professional engineer should know at least one compiled language such as Java, C, C++, or C# in addition to JavaScript, Python, and SQL. Additionally, he or she should be comfortable with another language such as Ruby, PHP, Go or Rust.

If you’re an application developer, do you only know one language? If so, I would strongly urge you to learn additional languages. Mastery of every language isn’t necessary, but any decent developer should feel capable of writing code in several languages.

Life’s Not Fair

When my daughter was young, she once complained to me about how one of my decisions wasn’t fair. I don’t remember what she asked for anymore, but I do remember my response. I told my daughter she should be thankful that life isn’t fair. Look around the world today and you see children starving in underdeveloped parts of the world, people being oppressed by cruel leaders, people suffering from lifelong disabilities, and all kinds of other suffering. Yet here, in America, we enjoy an incredibly high standard of living. Few of us die of starvation, we have a democratically elected system of government, and we have some of the best healthcare services in the world. I am thankful every single day that I have been blessed so greatly.

How does this apply to technology and business? As I run my business, I see how fortunate I am. I see that I am well paid, that I have freedom to enjoy life, and that I am the master of my own destiny. As I look around, I see that few others have that freedom. Even among the greatest nation on earth, I am among the most fortunate of people. As such, I have a moral obligation to make the world around me a better place. I am compelled to improve the community I live in, to better the lives of those around me, and to work to empower those I work with. I’m thankful life isn’t fair because it gives me an opportunity to make the world a better place. It gives my life purpose and meaning.

Making the world a better place should be part of the mission of every company out there. Is your business empowering employees? Are you making your community a better place to live? Are you serving more than your own pecuniary interest? Can you sleep at night with the decisions that you and your business make on a daily basis?

When we all work together, we can make the world a fairer place for all. We can work to ameliorate suffering and starvation. We can improve healthcare around the globe. Maybe, someday, the world will be a fairer place. Until then, each one of us – business and individual alike – has work to do.

Great Minds

It’s often said that “great minds think alike.” It sounds great, in theory. But is it really true? Just because I’m thinking the same thing someone else is, does that really mean we’re both great minds? I hardly think so. It’s not the employee who thinks the same as everyone else that brings value to the team, it’s the free thinker who has a different perspective. In the boardroom, when everyone thinks the same, we call it groupthink. Psychology Today says “In a groupthink situation, group members refrain from expressing doubts, judgments or disagreement with the consensus and ignore any ethical or moral consequences of any group decision that furthers their cause.” This hardly seems beneficial to the team. When I think of great minds, I think of the men and women who engaged in thought well outside the mainstream – brilliant men like Isaac Newton, Albert Einstein, Stephen Hawking, and Benjamin Franklin. If you want to be a great mind, think for yourself! Don’t let the people around you define your thought. Be willing to take risks and think outside the box. It’s those people who history remembers – not the people who think like everyone else.

Language Popularity

A subject that repeatedly comes up on websites, blogs, and conversations is which language is the most popular and which ones are the best to learn for future job opportunities. I keep an eye on this list myself as it’s important to understand trends within the software industry. However, people seem to ignore the most important aspect of language popularity – the context.

What do I mean by context? I mean we have to look deeper to understand why a language is as popular as it is. We also need to understand the market for a language and how that impacts popularity. For example, JavaScript is always near the top on any language popularity chart. Is it any coincidence that JavaScript is also the only front-end scripting language in use today? Whether or not you like JavaScript is utterly inconsequential. If you want a website with any manner of front-end scripting, you will use JavaScript. Likewise, if you want to interact with a database you use SQL and if you want a web page, it will be HTML. As such, these technologies will always rank more highly than those with a smaller market.

So what about Python? Everywhere you look, you see that Python is at the top of the list. Should we all switch to Python? Not really. What all those rankings fail to point out is the user base for Python. Certainly there are all kinds of production projects out there running Python. But if you look around, you see that Python’s popularity is largely caused by people outside the traditional developer community. AI researchers, academics, data scientists, system administrators, makers, etc. For non-programmers, Python is easy and incredibly powerful. But that hardly makes Python superior to other languages nor does it suggest that professional programmers should start porting their eCommerce sites.

Remember, while rankings of popularity may help you see trends, look to the underlying reasons. Why is it popular? Who is it popular with? Does this language look poised to overtake in other realms? When picking a language for a problem, the most important question is which language solves the problem best – not which language is the most popular.
