Hacker's Language - LEET

Ah, leet, the language of the geek.To speak leet, you more or less need to un-learn proper english. the history of leet goes back to the early days of online message boards, or forums, where users can post messages to carry on a threaded conversation. In an attempt to "clean-up" the language that users would sometimes post, admins added a filtering system to the message board which would replace restricted words with some type of alternative. For example, the word "crap" might become "crud." it didn't take people long to figure out that you could get around this filter simply by altering the original word somehow, like changing "crap" to "c-r-a-p" or "krap" or "crrrap." it was soon obvious that these filtering systems could never possibly cover every variation because people would just keep inventing new ones, and so leet was born.

                 In the most generic explanation, leet is merely replacing certain letters of the alphabet with numbers that bear a slight resemblance. l becomes 1, e becomes 3, t becomes 7, and so on… leet becomes 1337.

In a not so generic explanation, leet is also a play on words. the word leet itself is actually a shorter, easier way of saying the word "elite" which the dictionary defines as: the best or most skilled members of a group. An odd thing about the internet is that when certain trends catch on, they seem to spread on a massive scale. 

            

Other Resources for Hackers

Paul Graham has written an essay called Great Hackers, and another on Undergraduation, in which he speaks much wisdom.

There is a document called How To Be A Programmer that is an excellent complement to this one. It has valuable advice not just about coding and skillsets, but about how to function on a programming team.

He have also written A Brief History Of Hackerdom.

He have written a paper, The Cathedral and the Bazaar, which explains a lot about how the Linux and open-source cultures work. I have addressed this topic even more directly in its sequel Homesteading the Noosphere.

Rick Moen has written an excellent document on how to run a Linux user group.

Rick Moen and I have collaborated on another document on How To Ask Smart Questions. This will help you seek assistance in a way that makes it more likely that you will actually get it.

If you need instruction in the basics of how personal computers, Unix, and the Internet work, see The Unix and Internet Fundamentals HOWTO.

When you release software or write patches for software, try to follow the guidelines in the Software Release Practice HOWTO.

If you enjoyed the Zen poem, you might also like Rootless Root: The Unix Koans of Master Foo.

Status in the Hacker Culture

Like most cultures without a money economy, hackerdom runs on reputation. You're trying to solve interesting problems, but how interesting they are, and whether your solutions are really good, is something that only your technical peers or superiors are normally equipped to judge.

Accordingly, when you play the hacker game, you learn to keep score primarily by what other hackers think of your skill (this is why you aren't really a hacker until other hackers consistently call you one). This fact is obscured by the image of hacking as solitary work; also by a hacker-cultural taboo (gradually decaying since the late 1990s but still potent) against admitting that ego or external validation are involved in one's motivation at all.

Specifically, hackerdom is what anthropologists call a gift culture. You gain status and reputation in it not by dominating other people, nor by being beautiful, nor by having things other people want, but rather by giving things away. Specifically, by giving away your time, your creativity, and the results of your skill.

There are basically five kinds of things you can do to be respected by hackers:

Basic Hacking Skills

The hacker attitude is vital, but skills are even more vital. Attitude is no substitute for competence, and there's a certain basic toolkit of skills which you have to have before any hacker will dream of calling you one.

This toolkit changes slowly over time as technology creates new skills and makes old ones obsolete. 
For example, it used to include programming in machine language, and didn't until recently involve HTML. But right now it pretty clearly includes the following:

1. Learn how to program.

This, of course, is the fundamental hacking skill. If you don't know any computer languages, I recommend starting with Python. It is cleanly designed, well documented, and relatively kind to beginners. Despite being a good first language, it is not just a toy; it is very powerful and flexible and well suited for large projects. I have written a more detailed evaluation of Python. Good tutorials are available at the Python web site.
I used to recommend Java as a good language to learn early, but this critique has changed my mind (search for “The Pitfalls of Java as a First Programming Language” within it). A hacker cannot, as they devastatingly put it “approach problem-solving like a plumber in a hardware store”; you have to know what the components actually do. Now I think it is probably best to learn C and Lisp first, then Java.
There is perhaps a more general point here. If a language does too much for you, it may be simultaneously a good tool for production and a bad one for learning. It's not only languages that have this problem; web application frameworks like RubyOnRails, CakePHP, Django may make it too easy to reach a superficial sort of understanding that will leave you without resources when you have to tackle a hard problem, or even just debug the solution to an easy one.

The Hacker Attitude

Hackers solve problems and build things, and they believe in freedom and voluntary mutual help. To be accepted as a hacker, you have to behave as though you have this kind of attitude yourself. And to behave as though you have the attitude, you have to really believe the attitude.

But if you think of cultivating hacker attitudes as just a way to gain acceptance in the culture, you'll miss the point. Becoming the kind of person who believes these things is important for you — for helping you learn and keeping you motivated. As with all creative arts, the most effective way to become a master is to imitate the mind-set of masters — not just intellectually but emotionally as well. Or, as the following modern Zen poem has it:

WHAT IS A HACKER ???

The Jargon File contains a bunch of definitions of the term ‘hacker’, most having to do with technical adeptness and a delight in solving problems and overcoming limits. If you want to know how to become a hacker, though, only two are really relevant.

There is a community, a shared culture, of expert programmers and networking wizards that traces its history back through decades to the first time-sharing minicomputers and the earliest ARPAnet experiments. The members of this culture originated the term ‘hacker’. Hackers built the Internet. Hackers made the Unix operating system what it is today. Hackers run Usenet. Hackers make the World Wide Web work. If you are part of this culture, if you have contributed to it and other people in it know who you are and call you a hacker, you're a hacker.
