Java is “heavyweight, verbose, and everyone loves to hate it,” but Wall still thinks you should know it.
Question: What are the five programming languages everyone, even non-programmers, should know about and why?
Larry Wall: Oh, boy, that’s a really tough question. It’s kind of like asking what are the five countries you should know about if you’re not interested in geology, or geography, or politics, and the answer varies depending on what your actual interests are, or what are the five companies you should know. And the answer changes over time, too. Back when I was getting started, lo these many decades ago, the answers would’ve been Fortran, Cobalt, Basic, Lisp, and maybe APL, and those were very formative languages back then and people learned a lot from those, but these days, it might be more important for you to know JavaScript, even if the only reason you know that is that you know whether or not to click the “enable JavaScript” button in your browser. But JavaScript is a nice, lightweight, object-oriented language and that’s why it can fit in a browser and do these things such as run little programs that help you input your data and then send it off to a web server somewhere.
There are heavier-weight object-oriented languages and the elephant in the room is sort of Java, you can’t really make a list of modern languages without talking about it. Java is sort of the Cobalt of the 21st century, I think. It’s kind of heavyweight, verbose, and everyone loves to hate it, though not everyone will admit that. But managers kind of like it because it looks like you’re getting a lot done, you know, if 100 lines of Java code accomplish a task, then it looks like you’ve written 100 lines, even though in a different language, it might only take 5 lines. You know, it’s like, you know, you can eat a 1-pound steak or you can eat, you know, 100 pounds of shoe leather and you feel a greater sense of accomplishment after the shoe leather, but, you know, maybe they’re some downsides.
But it also, because it is sort of considered an industrial language and programmers are sort of interchangeable parts, managers like it for that reason, and for that reason, a lot of Java jobs have been outsourced from the United States.
Oh, what other languages? I think going in a different direction, coming more from academia, we have a language like Haskell, which we call a functional programming language. That means function in a mathematical sense, not in the sense the other languages are dysfunctional. But a function mathematically has an input and an output and it maps to, you know, with a great deal of mathematical certainty what those are. Haskell is one of those languages that mathematician-type-minded people love; it’s sort of a language for geniuses, by geniuses. So you should probably know about it, if only to be able to say, “Well, is this kind of like Haskell?” And if so, then you know you have to hire some really smart people to program in it. Haskell is sort of a modern kind of Lisp in that sense.
What else? Well, we can’t leave off modern languages without talking about C. The C language, that’s just spelled with the letter C, is actually about 40 years old, but people have tried to replace C with other languages that are like it and have by and large not succeeded because C is a very minimalistic language and very close to the metal, as we say, on a machine, and lets you get down and do very fine grain stuff, very efficiently, but it’s a lot of hard work. But once you’ve done that work, you can run it pretty much everywhere. So almost all the other languages that you see, Java, Perl, whatever, actually if you look down underneath, they’re actually implemented in C, or in a closely related language. So that continues to be a very fundamental language, if only because everyone is trying to reinvent it and not succeeding in doing so.
And finally, for a fifth language, well, you’d probably want to pick one of the scripting languages. There’s several to choose from, there’s Python, there’s Ruby, but of course, I am prejudiced in favor of Perl, because I think it has the liveliest community and because we have intentionally been redesigning it lately to leapfrog all the other languages. For the last number of years, we’ve been redesigning it to out all the warts that we’ve noticed over time. And we figured it was just our one chance to break backward compatibility, break the things that need breaking, keep all the things that make Perl, Perl, keep it a joy to use, and with this redesign, make it a language that will be able to be useful and enjoyable for decades. And so I’d recommend Perl, but I’m known to be prejudiced in the matter.

Are Larry Wall and Eric Raymond twins!?! LOL
I would go with JavaScript, PHP and MySQL (in compination with HTML5 and CSS) and you have everything you need for the Web.
On the Computer use Java* and C or other C-like languages for big tasks; python/batch/cmd/powershell-scripts for small ones.
On smartphones and tablets: Java is also the language for (andriod) apps. I don't know this apple swift but I heard it has a similar syntax.
Why the fuck did i fall in love with that guy? '-'
Is he still trying to sell Perl? Here's my Top 5:
Java, JavaScript, Go, Python, and Ruby (In no particular order).
Perl? Are you kidding me?
python
nimrod
maybe haskell
but javascript………………………………………..
This guy looks like an extra from Boogie Nights
All you need is C boys.
1- C 2 – java 3- assembly – 4
bash 5c++i kind of feel the same about java. I think its no accident that most websites and cms are written in php.
go Larry !
Are there anyone knows what can I do with my BSc degree in CS except programing…
What you guys think about C++?
2:33 … dude realised he was a homo
I started learning C a few weeks ago. I've worked with a few other languages over the past ten years or so (PHP, ActionScript, Javascript, etc.), and I am very impressed with how C works by comparison. I've never been a fan of the looser languages, and it's also nice to see how close you can get to machine level with C (if you want), but still pull off fast and powerful actions with basic code.
Still a rookie, though, so I have a long way to go.
LISP — "Lots of Stupid Parentheses"
Larry Wall recommending perl? That's weird
this guy is pretty funny
what about rubby you stupid fuck
what a cool guy
1)Java
2)Python
3)PHP/pearl
4)C++
5)C
The only language you need to know is LISP.
“Historically, languages designed for other people to use have been bad: Cobol, PL/I, Pascal, Ada, C++. The good languages have been those that were designed for their own creators: C, Perl, Smalltalk, Lisp.” – Paul Graham.
so… programming Java is like eating shoe leather?
My Top 10 Programming Languages:
1. C++ (<3)
2. Java (Swing all dayyy)
3. C (mm printf)
4. Python (simple syntax is simple)
5. Ruby (gets)
6. JavaScript (I don't even function)
7. Batch (is it even a programming language?)
8. VBScript (ugh)
9. lolcode (not a widely known language, pretty funny though)
10. C# (plz)
