If you're searching for a fountain of youth, the easiest way to get that feeling of continual rebirth is to hang around a few tech product launches. Every new rollout comes with the fresh, unabashed feeling that this has never been done before. Ever.
But it has. Apple has been bringing us "one more thing" for more than 30 years. Even the iconic commercial introducing the Macintosh is nearing 29 years old. Newness has never been so old.

Hype notwithstanding, the computer industry has already been through a number of generations. IBM has roots in tabulating companies that began about 130 years ago. That's three 40-year generations of tabulation and computing work without overlap.
In practice, new generations overlap quite a bit. The Internet is easily more than 30 years old, but it wasn't widely open to nonresearchers until about 20 years ago. During those 20 years, there have been at least three different bubbles, each with a feeling all its own.
These generations each have a distinctive flavor, often defined by a programming language or technology. They burst out with newborn fervor before settling into a comfortable middle age. They may not be on the top of the pop charts after a few years, but they're often still kicking because software never really dies. It's always running in some corner of a stack, somewhere somehow.
These new technologies often group programmers by generation. When programmers enter the job market and learn a language, they often stick with the same syntax for life -- or at least as long as they can before having to make a switch. It's not that it's hard to learn a new language; they're all pretty similar underneath. It's just that you can often make more money with the expertise you have, so the generations live on.
Here is our guide to some of the more dominant tech generations in computer history, as embodied by the programmers who gave them life. The list is far from complete, but if you've been coding for any amount of time, you will probably recognize many of these generational traits in yourself, your coworkers, and the programming community at large.
The '60s-era computers received their instructions from a stack of card with punched holes, a scheme that dates to the earliest programmable looms for weaving cloth. Some enterprise programmers talk about old software as "dusty deck," which is largely a metaphor. There was recently a story about a punch card programmer for looms in England that still use the old technology to make lace.
Language of choice: FortranSpecial skill: Not dropping the deck of punch cards

Song: Ella Fitzgerald's "Mack the Knife"
Favorite artifact: Wreath made of punch cards
This crew just retired with the Space Shuttle. During their years, they worked with 8086 chips and kept the shuttles running by searching eBay for replacement hardware. The Space Shuttle computers may not have had much memory, but they traveled farther and faster than all of the biggest mainframes or fanciest racks.
Language of choice: Assembly code

There was a time when the fastest computers were built by a relatively small company run by an enigmatic genius who spent his off-hours digging tunnels in his basement. That's a true fact about Seymour Cray, the genius who built the first generation of machines designed for big data sets and complicated mathematical analysis.

The first big adopters of computers never would have succeeded without a simple mechanism for writing software that supported the core business. Cobol was the first great tool for writing what the enterprise programmers call "business logic."
Other language of choice: Fortran

It was first invented to help Dartmouth students learn how to write endless loops, but it became the dominant language of the early personal computer generation when Bill Gates released Microsoft Basic. All of the early games and software for the PCs were written in Basic. Today it lives on as Visual Basic, a popular language for anyone using the .Net platform.

The language began as one step above assembler, but grew hand in hand with all of the variations of Unix. Today it's still used by those who love Unix and its latest dominant variant, Linux. It remains the tool of choice for those who want to program "close to the metal" and not rely on automatic mechanisms like garbage collectors.

When C programmers looked at the idea of object-oriented programming, they created C++, a baroque version that worked best when the programmer was able to keep track of all the complicated ways code could interact. It took all of the garage-grade DIY intensity and added another way for programmers to prove themselves worthy.

The simple language for manipulating text files appeared around the same time as the Internet, so when people needed to fix Web servers, they turned first to Perl. If you have text in one format and need to change it -- "massage it," in Perl parlance -- it may only take 10 to 20 characters. Most of the Perl scripts may be short, but that never stopped some true believers. Slashdot, after all, was built with Perl.

Favorite artifact: First edition of O'Reilly's Perl handbook
PHP programmersMany PHP programmers fell into PHP by accident. They were creating HTML, and they needed a bit of dynamic logic. One tag led to another, and they found themselves creating websites and content-management systems with the code.
Special skill: Juggling the coding layer and the HTML markup
Social media strategy: More than 1,000 friends on Facebook; still logs into MySpace

They fell in love with Java but remained loyal to Microsoft, perhaps because the boss insisted on keeping it a Microsoft shop. The code looks similar. The idioms work the same way. It's pretty much the same as Java, but with a few nice fixes worked into the mix.

Ruby on Rails programmers
Ruby on Rails programmersIt takes all of 10 minutes to wrap a nice website around MySQL, then years to fiddle with it. The Ruby language offers a clean, low-punctuation syntax, while the Rails framework makes it easy to type the smallest files around. It's almost as if it were designed by carpal-tunnel sufferers.

Special skill: Getting your stack to run on JRuby
Social media strategy: Writing a personal version of Facebook in 20 lines of code

Special skill: Figuring out how to make the layout manager work
Social media strategy: Posts pictures to Instagram and Hipstamatic but never uses words

Favorite artifact: DM from Brendan Eich
The language of the future offers a functional, statically typed mechanism that can reduce some of the complexity for writing modern, event-driven code. While the first implementations are easily more than 20 years old, the main users are still found in universities, but that's changing as cool open source projects gain traction. Haskell lovers insist this proves it will be the hot language in the 2020s.
Other language of choice: ML

The tool for building map/reduce jobs is technically not a language, but a collection of libraries written in Java. Not that it matters -- writing the code requires a talent for spotting the best way to spread out the workload over a cluster of machines. As long as "big data" remains a buzzword that captivates the corporate leadership, we'll see more exploring the best way to write Hadoop jobs.
Other language of choice: Java
Special skill: Making sure the data is always local
Social media strategy: Yahoo coding conferences
