Displays with wrong aspect ratio for me. Which makes Steve Jobs look pretty fat. On YouTube, it has the correct aspect ratio: https://www.youtube.com/watch?v=

Displays with wrong aspect ratio for me. Which makes Steve Jobs look pretty fat. On YouTube, it has the correct aspect ratio: https://www.youtube.com/watch?v=DmCu97u35Ek https://www.youtube.com/watch?v=DmCu97u35Ek How do we find the car of the uploader? Relevant XKCD: https://xkcd.com/1187/ https://xkcd.com/1187/ Some perspective on the presentation: At 13:20 or so, Jobs says "Of course you need a compiler, because a scripting language would be too slow for the server if it is used by a lot of users". Little did he know ... PHP was out for about a year when this presentation was given. Still lives today and powers most of the web.

But Facebook compiles PHP into C++ or something right (I think now they have a newer approach than c++)? https://en.wikipedia.org/wiki/HipHop_for_PHP https://en.wikipedia.org/wiki/HipHop_for_PHP

  The top-of-my-head story is that PHP5 was quite slow, Facebook's HHVM was PHP-compatible and fast. PHP7 was competitively fast with Hack. In terms of "performance needed for many users", Facebook doesn't use PHP (a "scripted language") for everything. etc.

    HHVM now mainly only targets Hack these days.

PHP was a C front end at first...

  Edited: you might be thinking of C++ ? I don’t think php ever compiled to C, based on a quick scan of the Wikipedia page. I thought it compiled to perl at one point but that doesn’t seem to be true either.

    It never compiled to C, but it was first intended to only provide bindings to libraries that were written in C.

    Iirc it was kind of like a templating language first. Imagine writing a cgi-bin c application and becoming tired of writing out HTML with printf statements.

  Facebook (HipHop for PHP) transpiled PHP to C++ but that 15 years into its life.
