<!-- 
  When an input element gets focused, iOS Safari tries to put it in the center by scrolling (and zooming.)
  Zooming can be easily disabled using a meta tag, but the scrolling hasn't been quite easy.

  The main quirk (I think) is that iOS Safari changes viewport when scrolling; i.e., toolbars shrink.
  Since the viewport _should_ change, it thinks the input _will_ move, so it _should_ scroll, always.
  Even times when it doesn't need to scroll—the input is fixed, all we need is the keyboard—
  the window always scrolls _up and down_ resulting in some janky animation.

  However, iOS Safari doesn't scroll when the input **has opacity of 0 or is completely clipped.**

// Nullify the transforms of the element
// 
// This is all behaving just like getBoundingClientRect() but it nullifies all the transforms
// and kinds _reverts_ the element onto its original position.
// This will work even with complex translations, rotations.
// The beauty is in the way it applies matrix inverse onto the transformation
// matrix and mutates the getboundingclientrect along the way.
//
// Usage:
// let { top, left } = nullifyTransforms(el);

This pure javascript function allows to dynamically include a script and then execute any function by using a callback.

function loadScript(url, callback){
	var script = document.createElement("script");

Fallout 1 (and Fallout 2) Hi-Res Patch for Mac OS X

Fallout 1 was originally designed to run at 640x480 resolution. I wanted to run the Mac OS X version of Fallout on my MacBook 11", which has a 1366x768 display. There is a [high resolution patch][hi-res], but it only supports the Windows version of Fallout.

Turns out that the OS X version of Fallout runs through Wine, so we can get this patch working with just a few configuration changes:

Note for Fallout 2 users: The process for Fallout 2 is essentially the same, with a different patch, and some minor pathing differences. Other than that, the process is exactly the same!

还记得 Haskell Curry吗，

多巧啊, 人家姓 Curry 名 Haskell, 难怪 Haskell 语言会自动柯里化, 呵呵. 但是不奇怪吗, 为什么要柯里化呢. 为什么如此重要导致 Haskell 会默认自动柯里化所有函数, 不就是返回一个部分配置好的函数吗.

我们来看一个 Haskell 的代码.
