Escalating

# Eirik? - Web developer from Trondheim, Norway - Fan of beer, programming and GIFs - Although a beer geek, not a beer snob (true story)

A story

Based on real events

Once upon a time there was a web developer called Eirik Eric

He was a PHP developer

          strpos($haystack, $needle);

in_array($needle, $haystack);

            Temperature is 19.875

          setInterval(function() {
  var file = '/var/www/index.php';
  var contents = '<?php print "Temperature is ' + temp + '";'
  require('fs').writeFileSync(file, contents);
}, 1000);

Continious deployment?

## JavaScript everywhere

# Can we measure something else than temperature

# Escalation in progress

> Well, Eric. This stuff sure is geeky. And I know you are always calling my new synthesizer projects geeky. But you know what would be even more geeky? If we combined these things. Make the fermentation of the beer feed midi notes into a synthesizer. Real-time _Synth geek friend of Eric_

> Such interdisciplinary geekyness _Eric_

> I know, right _Synth geek friend of Eric_

# What can we do with all this data?

Another story

Once upon a time there was a web developer called Eirik Eric

He was a PHP developer

Parse error: syntax error, unexpected (T_PAAMAYIM_NEKUDOTAYIM)

Bought when he was 20 years old, because he never got one as a kid

Eric had a tradition with his brothers. Every christmas, they would do something geeky with this slot car track This is 2 years ago

>But this Eric was also in the escalating business
