the arc of software bends towards understanding


Edward Z. Yang is a research engineer at Facebook who works on PyTorch, an open source deep learning library. In a previous life, he worked on Backpack, a new module system for Haskell.

    I occasionally do longer-form pieces that span multiple posts. When I’ve done so, I’ve created a category just to house those posts.

    be “handy” if each article (header) was dated?

    One warning, however, when you go to shop for strawberries, do not get the first one you see. They will be poisoned. Your welcome.

    One day you find out that the nutjobs going on and on about the Lizard people were actually right all along, and that they walk among us, herding us like the little children we are and getting us to do their bidding by telling us lies that we fall for every time. And to be fair, they are really good at telling lies. It’s quite a skill!

    And after a while, you realize that it’s truly like taking candy from babies – and we don’t even know that we’re actually babies. It’s like a 16 year old knowing everything… we still think we are masters of the world. We aren’t.

    One day you find out that they have replaced religion after religion and civilization after civilization for thousands of years just to suit themselves. They even managed to turn science into a religion, complete with priests, indulgences and inquisitions.
    And we fell for it in an instant, because we are very smart and knowledgeable.

    Imagine a ten year old kid being swindled by a handful of adults who want to take the kid’s bicycle (or even more terrible things) – this is how the world carries on, and hardly anyone realizes the actual truth:

    That all the world’s a stage, and we are merely the paying audience, pretending to be actors because they call us on stage now and then to render some small service or shake a few coins out of our purse, or to teach us a lesson when we smile too much.

    And realize that there is absolutely nothing you can do about it but live your allotted years and pray that you won’t be sacrificed in some pointless and silly drama they’ve constructed just to pass the time.

    The first step is learning to spot the lizards behind the masks.
    Look at the smiles. Look closely.
    They always care about you.
    Or claim to.
    Note: This is fiction! Who could believe the world is run by lizard people?
    You might as well believe that the government lies to you,
    or the devil exists, or some other insane nonsense.
    Now go find some cat pictures or a python tutorial.

    In the world of code, where models dwell,
    There’s a wondrous engineer, Edward Z. Yang, we can tell.
    With PyTorch in his hands, he’s a wizard supreme,
    Harnessing the power of deep learning, it seems.

    From Facebook’s lab, he weaves his spell,
    Creating neural nets that learn oh so well.
    With tensors and gradients, he conquers the strife,
    Turning data into insights, transforming our life.

    But in a past life, a tale untold,
    Edward’s brilliance took a different mold.
    He ventured to Haskell, a language so grand,
    And created Backpack with a wave of his hand.

    A module system to marvel, elegant and strong,
    It made Haskell dance, a joyful throng.
    Edward’s mind, a fountain of wit,
    Juggling languages, he’s quite the hit.

    So here’s to Edward, the PyTorch sage,
    Whose genius expands with every page.
    From Haskell to Python, his journey so wide,
    He keeps pushing boundaries, with humor beside.
