  • Historically, reverse proxies were invented to manage a large number of slow connections to application servers which were relatively resource intensive. If your application requires N bytes of memory per transaction then the time between the request coming in and the response going out could pin those bytes in memory, as the web server can’t move ahead to the next request until the client confirms it got the whole page.

    A reverse proxy can spool in requests from slow clients, when they are complete, then hand them off to the app servers on the backend, the response is generated and sent to the reverse proxy, which can slowly spool the response data out while the app server moves onto the next request.










  • Vertical integration is when you control the entire product, in consumer electronics Apple is the gold standard; they make the software, hardware, and processors then integrate them into iPhones and macBooks. Tesla is a good example in the automotive space, their goal with the mega-factories is “raw materials in, cars out” and they work to build as many of the parts themselves as possible.

    Alternately Microsoft just makes a good enough OS that runs on good enough hardware from commodity vendors, so you get good enough computers. Most auto makers buy good enough components from 2nd and 3rd tier suppliers and integrate them into good enough cars.






  • LOL WUT?

    Android was originally a button and keyboard driven mobile OS, when the iPhone was released they scrambled to switch the UI to touch.

    When given detail about them – and asked whether he would say that any elements in the latest version of Android, such as the two-line preview of emails in the Gmail app (found in Apple’s iPhone email program since 2007), or the “quick response” buttons at the bottom of the email app (almost identical in order and purpose to those in Apple’s iPhone email program), or the provision of a shortcut to the camera from the phone’s lock screen (first seen in Windows Phone 7 in October 2010 iOS 5 previews in June ), or the extra features added to the Notifications bar in Android – were copying iOS, he responded: “I’m not going to get into this.”
