Why I Program In Ruby (And Maybe Why You Shouldn't)

In the past 2 years I've adopted Ruby for 99% of my coding needs. My experience sounds different to yours:

I started with plain C when PCs were so slow you needed a compiled language. When I moved from C to C++ in order to better write Windows applications, it was nice to have classes, constructors/destructors to make memory management easier, but the other stuff (eg. templating system and supplied hash/array/string classes) caused pain and I avoided it.

I was excited about Java. It seemed like a cleaner language for ex-C programmers to move to OO, but then I got really irritated when trying to actually use it for developing real applications, for all the reasons you mentioned.

I kept searching, dabbled with functional programming in Haskell, and happily used Perl for a long while until finally discovering Ruby.

To me, Ruby was like a Perl that really was more enjoyable to use. By that I mean I really value a system that quickly lets me express my thoughts and lets me get applications up and running faster. Often, well-written Ruby looks like pseudocode.

In my case, subconsciously the enjoyment factor of the language really was a stumbling block that slowed down my progress on my projects.

There have been no downsides. CPUs haven't stopped getting faster since my first steps in ASM/C 15 years ago, so I have no Ruby performance problem. Architectural changes that Ruby enables make it fun to write performant code.

I agree that a language should be chosen primarily for the features that suit your needs. Expressiveness, stability, reliability, etc.

But within a given domain, there is often no clear choice which has the best features. This is especially true for Ruby, Python, and Perl. Some people are happy in the fires of CPAN hell, for example.

I lost you at the beginning of the 2nd paragraph. Nobody who knows how to muscle their ways in C++ feels good after transitioning to Java. There is nothing "liberating" in this hog for someone who knows C++. There is nothing in Java that one can call "beautiful" or "enjoyable". I am sorry to sound like an idiot (yes, I have re-read what I just wrote) but I cannot help it - Java is full of hidden messages like "oh, we feel like you're too stupid to have this or that kind of power, so just sit in a sandbox and enjoy the ride". And indeed, most programming idiots I've met in my career called themselves "Java programmers".

No statically typed language without powerful template system nor multiple inheritance of some sort should be considered usable in this age and time. Java/C# (same shit) was designed for "enterprise software" development, something a CS grad should never, never, never consider doing.

Ruby is the opposite of all that - Ruby represents ultimate freedom of expression. C++ runs circles around Java in that regard. Ruby only takes it several levels higher. In Ruby you really do feel like changing the world, as long as your world is written in Ruby as well. It's sad you missed it as the main point of the great post.

P.S. Go get yourself some decent C++ book.

That was how I've always seen Ruby and Python. I've tried Python before and didn't like it. It had nothing to do with any technical reasons and was purely aesthetics.

The article's main point is that Ruby is supposed to make you feel good. It's origin is Japanese, and the language itself is more like a Zen garden. 'Harmony' is a word that has as much impact in the Japanese and Chinese cultures as 'freedom' and 'dream' does in America. Although diluted from its contact with the youthful American culture, those cultures has a fascination with ancient, or at least the wisdom of the elders. Here, there is a fascination with the youthful and the new. That's why you see news of 12-year-old kid raising $6 million in VC funding for an MMO e-commerce product.

In Chinese and Japanese stories, both old folklore and current modern renderings of it, there are stories of the young getting rewarded for listening to the old sages. In the Japanese stories in particular, there is a common theme of the older generation passing on the world to the newer generation by allowing them to make their own mistakes while having faith that they will survive and prosper. Translated into American terms, at best you would hear "get rewarded for working hard", and "we're younger so we know what's 'cool'."

So you hear a lot of news of young startups and the kids that started them up. When you hear of old Mrs. B starting up a new furniture chain because she had a disagreement with the upper management of the company she owned and sold to Warren Buffett (http://mba.tuck.dartmouth.edu/pages/clubs/investment/WarrenB... ), you don't get the sense that Mrs. B is lording it over her hirelings, "You should do this because in my experience ... ". Instead, you get the sense that at age 97, Mr. B. is still more youthful and active than the executives she hired in her first company.

The point is that the cultural undertones of 'harmony' gets seriously lost when transplanted into the American culture. People here often have other reasons for picking up Ruby.

So why might someone here write in Ruby? Because its expressive power gives you the freedom to make real what only you can see (vision). Because you can concentrate on improving the product and add new features. Because it is part of the current crop of technologies that lowers the requirements for a startup ... so you can drop everything, pursue the American dream -- write something millions want to use, make some big bucks, and retire young so you can enjoy the rest of your life. Or at least before you hit middle age.

Is this a long-winded way of saying that two wrongs make a right? That if "they" use torture we ought to use torture? That...

Oh, sorry, my mistake, I thought I was on reddit. I'm actually on ycombinator, which is a completely different community. Let's talk about startups, please.

Maybe I am over analyzing: Given the current visibility of Islamic extremism, its less distracting to talk about current non-issues.

the fact that it could be said about any language is part of his point. ruby isn't the one true language. just program in whatever language makes you feel good, be it ruby or not. nevertheless, some languages feel more zen-like on the average. for instance, find me one person who ever felt good programming anything in cobol.
