  1. Not Synced
    [piano music]

  2. Not Synced
    [applause]
    What Ano didn't want to say
  3. Not Synced
    is that programming languages are my
    substitute girlfriend. [laughter]
  4. Not Synced
    It's easier to get a relationship with a
    programming language than a, you know
  5. Not Synced
    But you have to take her kind of dating
    course.
  6. Not Synced
    Alright! Since I'm going to maybe insult
    some people, you know, maybe I step on
  7. Not Synced
    some toes, I just want to say kind of, you
    know, this is just my personal opinion
  8. Not Synced
    Also, I want you to think about this and
    then make your own decisions.
  9. Not Synced
    All I want to do is make you think,
    and ultimately you decide for yourself.
  10. Not Synced
    Alright! Of course, you expect a talk
    where I'm going to go and scream and
  11. Not Synced
    curse and talk about how HR and Scrum
    are cancer that needs to be eliminated
  12. Not Synced
    from this industry, right? That's what you
    all signed up for, you all kind of have
  13. Not Synced
    your beers, your snacks ready. Um,
    I have to say this talk is not going to be
  14. Not Synced
    like that. And what I want to do is I want
    to take you back to a little bit of some
  15. Not Synced
    recent history. And in 2013 I left
    Microsoft. This was when Vollmer was
  16. Not Synced
    kind of in charge; now he's doing some
    basketball team.
  17. Not Synced
    Think that's way better for him.
    [laughter]
  18. Not Synced
    But, you know, I left Microsoft with the
    goal to make the world asynchronous
  19. Not Synced
    and reactive. So I founded this small
    company, Applied Duality, that was trying
  20. Not Synced
    to do that. And then, in June, one of the
    first customers I had was Facebook where
  21. Not Synced
    I worked with them on a language called
    Hack. Hack is a version of PHP that looks
  22. Not Synced
    like a version of PHP that looks like
    PHP but under the covers it's really OCaml
  23. Not Synced
    Facebook is all written in Hack but really
    it's written in OCaml with Hack syntax,
  24. Not Synced
    with PHP syntax.
  25. Not Synced
    So funtional programming-- if you're not doing functional programming yet, you're already behind.
  26. Not Synced
    So who here is not doing functional programming? OK, you can go home now [laughter]
  27. Not Synced
    and maybe do a startup course but in a few years it will be obsolete. [laughter]
  28. Not Synced
    And then slightly later that year I started to work with Netflix on RxJava
  29. Not Synced
    and I guess there is this thing has been a runaway success I think a lot of people are using it that has gone beyond my wildest dreams.
  30. Not Synced
    Let's look at 2013-- eh 2014. At Microsoft I did programming languages as a hobby
  31. Not Synced
    but it turned out with my startup that it became a way to make money.
  32. Not Synced
    So in April 2014 I worked with Google on Dart

  33. Not Synced
    and there I helped Dart to get also support for asynchronous programming ASynch 08
  34. Not Synced
    And Dart already had support for streams and now we put our API in API for streams
  35. Not Synced
    and now we put that in the language as well.
  36. Not Synced
    So Dart is one of the few languages that has gone up complete support for synchronous, iterators, ASynch 08
  37. Not Synced
    and streams all build in the language.
  38. Not Synced
    If you haven't looked at Dart yet, I would really say: give it a try just like you should give Hack a try.
  39. Not Synced
    And then in September 2014, I gave the Hackile Talk that you are all expecting to see, but that you don't get.
  40. Not Synced
    But that talk was my interpretation of what I saw in Silicon Valley.
  41. Not Synced
    I moved from the Pacific Northwest to Silicon Valley and
    I worked with a lot of the internet companies there.
  42. Not Synced
    And I was really impressed by the way they
    developed software.
  43. Not Synced
    I was really impressed by the way that they look at software, and that's what I wrote down.
  44. Not Synced
    And I will talk a lot more about this in the rest of the talk.
  45. Not Synced
    And then in October last year, I did the FP101x mooc,
  46. Not Synced
    where I tried to teach the world about functional programming.
  47. Not Synced
    The mooc starts again October 15, the second edition.
  48. Not Synced
    So don't despair if you put up your hand, not doing functional programming, because there's your chance
  49. Not Synced
    to learn functional programming.
  50. Not Synced
    Alright. And then disaster struck. On Christmas Eve 2014, my leg was swollen.
  51. Not Synced
    My left leg was swollen, and when I put on my PJ's.
    So I told my wife, I don't trust this, my leg is all swollen.
  52. Not Synced
    So we went to the Stanford Emergency Room.
    And of course, you know, it's Christmas Eve,
  53. Not Synced
    so you wait for a few hours. And then, the doctors talked to me and said, 'okay, it's okay.
  54. Not Synced
    Probably you ate curry or some salt food, you can go home.'
    So I went home, and I went to bed.
  55. Not Synced
    It was like around 4AM in the morning.
    And then at 6AM, I got a phone call.
  56. Not Synced
    And I still have that phone call right here on my saved messages, in my voicemail box.
  57. Not Synced
    And the doctor said, 'Sir, when we did your blood test,
    the white blood cell counts were a little bit
  58. Not Synced
    out of wack.' And then I asked him, you know, 'what does that mean?' And he was like, 'uh uh,
  59. Not Synced
    well, sir, if you want to have Christmas with your family then it's okay, you can come in tomorrow.'
  60. Not Synced
    So, I did a quick Google search: "high white blood cell counts." And that's not good, I can tell you.
  61. Not Synced
    [laughter]
    It's not good. Okay? So what I did, we took the car,
  62. Not Synced
    went back to Stanford. And at 8AM, I was in the Oncology section, and I was diagnosed with
  63. Not Synced
    this thing called CML - chronic myeloidic leukemia.
    It sounds crazy, but actually if you want to have
  64. Not Synced
    form of cancer, this is what you want to pick.
    [laughter]
  65. Not Synced
    This is really what you want to pick. So what happens - this is the CliffsNotes version - what happens is that
  66. Not Synced
    all of our DNA constantly gets damaged, and your body tries to repair it. And sometimes that repair can go wrong.
  67. Not Synced
    And in this case, two parts of a chromosome kind of switch. So they get glued back together in the wrong place.
  68. Not Synced
    And again, this is CliffsNotes, I'm not a medical person. So if there's somebody here with medical background,
  69. Not Synced
    they will probably laugh, but you know, just trying to explain this in computer science terms. [laughter]
  70. Not Synced
    So what happens, it's like fuzzing. Fuzzing of your DNA.
    And what happens, you know DNA makes proteins,
  71. Not Synced
    and now that this program is wrong - so they've just switched two statements around - it creates a protein that your body
  72. Not Synced
    doesn't recognize. And that kind of fucks everything up.
    Well, the nice thing about science is that they came up with
  73. Not Synced
    a medication that binds to this particular protein. It's like an exception handler, it catches the exception and that's it.
  74. Not Synced
    [laughter]
  75. Not Synced
    So everyday, I take this pill. If I would have to pay it without insurance, I would be broke.
  76. Not Synced
    So my life- I can now count how expensive my life is. It's like a few hundred dollars a day for this pill.
  77. Not Synced
    But I'm happy that it exists.
    So as I said, that was that.
  78. Not Synced
    But if that was the only story, life would be good, right?
    It's just, 'okay, you know, my DNA got messed up,
  79. Not Synced
    I pop a pill every day, life goes on.' But of course,
    being Erik Meijer, things are never simple in my life.
  80. Not Synced
    And instead, a couple of things went wrong. So this was me around New Year's Eve. I was close to dying.
  81. Not Synced
    Because what happened is that I got some internal bleedings,
    and one of the effects of leukemia is that your spleen-
  82. Not Synced
    this is the thing when you're running, you know, you feel pain in your left side? That's your spleen.
  83. Not Synced
    Your spleen gets enlarged. And when your spleen gets enlarged, it takes up all the space in your abdominal section,
  84. Not Synced
    and so I got some bleedings, for whatever reason. And since there was less space, the blood could not go anywhere,
  85. Not Synced
    so my kidneys were kind of pushed out- I don't know, like 50 centimeters from where they were supposed to be.
  86. Not Synced
    So I got a- I don't know what the doctors called it-
    acute kidney injury. And then they have to open me up.
  87. Not Synced
    If you're curious, I can show you. I have like a big, you know, kind of... wound here. Everything that's soft in the belly,
  88. Not Synced
    they opened up to go in there. I spent five days in intensive care, I was nearly dead. If I had wanted, I could have just
  89. Not Synced
    floated away, and you know, just given up. But I was fighting because my journey wasn't over. I had to still, you know
  90. Not Synced
    eliminate SCRUM and AGILE from this world, so how...
    [laughter, applause]
  91. Not Synced
    How could I die? Alright? But anyway, it was pretty horrible, and I can tell you, one of the things that people-
  92. Not Synced
    that happens to people when they are in intensive care, is they literally go crazy. There's a medical term for that,
  93. Not Synced
    and I can understand that. It's a bizarre experience. I don't know if anybody here has ever been in intensive care.
  94. Not Synced
    They probably know what I'm talking about. Alright, so that was the end of 2014. And not the kind of Christmas vacation
  95. Not Synced
    I was expecting. But hey, you know, I'm still here.
    So early January, I was released from the hospital.
  96. Not Synced
    Because of the kidney moving around, all the nerves that kind of traveled to my leg were displaced. And kind of a little bit,
  97. Not Synced
    you know, out of wack. So I couldn't walk anymore, my whole right leg was, you know, I couldn't move it. So I had to
  98. Not Synced
    learn to walk again because I had the breathing tube in for a couple of days. I lost my voice, I couldn't even speak,
  99. Not Synced
    I was like [gasping]. So they went in with a syringe and injected straight through my throat some stuff to make it work.
  100. Not Synced
    So all kind of fun things, you know. The body is kind of a remarkable machine. So that was fun.
  101. Not Synced
    And then, of course, when something like that happens you start to think about, 'what is the meaning of life?'
  102. Not Synced
    'What am I doing on this planet?' Blah blah blah.
    [laughter]
  103. Not Synced
    And it took me literally 6 months to get back to normal. And it was quite a big journey. But as I said, when something
  104. Not Synced
    like this happens to you, you really start to think, 'what do I want to do with my life?'
  105. Not Synced
    And then in July, Mark Zuckerberg asked me about Rx, and how that could help solve giving people that are on 2G
  106. Not Synced
    a better experience- a better Facebook experience. Now, you may have seen the article by Mark Zuckerberg and Bono
  107. Not Synced
    about giving everybody access to the internet. Well, that kind of appealed to me because what I wanted to do is, you know
  108. Not Synced
    like after this whole event, can I make my technology do something for real people? Okay? So it's great to kind of
  109. Not Synced
    talk about Rx and programming languages for other geeks, but what I wanted to do was really use what I do
  110. Not Synced
    for normal people. For the world, to do good for the world. That's what I came up with after I reflected about life.
  111. Not Synced
    And when Mark Zuckerberg asked me that, I said, 'Well, that sounds really good. That sounds like a nice combination
  112. Not Synced
    of my technical stuff and a real opportunity to help people in the real world.' You have seen what happened now with
  113. Not Synced
    the refugees here in Europe. They use Facebook to find their way. It's kind of amazing how this really effects
  114. Not Synced
    normal people and improves their lives. And this is something I think fits right in with the new Erik.
  115. Not Synced
    So, just a few weeks ago, I joined Facebook.
    And that's what I'm going to do now.
  116. Not Synced
    So my startup adventure was short but sweet, but thanks
    to this big life-changing event, I think I can spend my
  117. Not Synced
    few years that I might have on this planet to really help
    the big population of this earth.
  118. Not Synced
    By the way, if there's questions at the end, I have
    a whole bunch of t-shirts here for people that ask questions.
  119. Not Synced
    They will get a nice Facebook t-shirt. You see here?
    Isn't that beautiful? [laughter]
