The function setcontext() restores the user context pointed to by ucp. A successful call does not return. The context should have been obtained by a call of getcontext(), or makecontext(3), or received as the third argument to a signal handler (see the discussion of the SA_SIGINFO flag in sigaction(2)).

Use sigaction() unless you've got very compelling reasons not to do so. The signal() interface has antiquity (and hence availability) in its favour, and it is defined in the C standard. Nevertheless, it has a number of undesirable characteristics that sigaction() avoids - unless you use the flags explicitly added to sigaction() to allow it to faithfully simulate the old signal() behaviour.

This means that the output can be displayed to a user, for example the app is 95% sure that this is a cat. It also means that the output can be fed into other machine learning algorithms without needing to be normalized, since it is guaranteed to lie between 0 and 1.

Typically, the final fully connected layer of this network would produce values like [-7.98, 2.39] which are not normalized and cannot be interpreted as probabilities.

yield 的作用就是把一个函数变成一个 generator，带有 yield 的函数不再是一个普通函数，Python 解释器会将其视为一个 generator，调用 fab(5) 不会执行 fab 函数，而是返回一个 iterable 对象！

Fab 类通过 next() 不断返回数列的下一个数，内存占用始终为常数：

由于Python源代码也是一个文本文件，所以，当你的源代码中包含中文的时候，在保存源代码时，就需要务必指定保存为UTF-8编码。当Python解释器读取源代码时，为了让它按UTF-8编码读取，我们通常在文件开头写上这两行：

你可能猜到了，%运算符就是用来格式化字符串的。

在计算机内存中，统一使用Unicode编码

UTF-8编码有一个额外的好处，就是ASCII编码实际上可以被看成是UTF-8编码的一部分，所以，大量只支持ASCII编码的历史遗留软件可以在UTF-8编码下继续工作。

又出现了把Unicode编码转化为“可变长编码”的UTF-8编码。UTF-8编码把一个Unicode字符根据不同的数字大小编码成1-6个字节，常用的英文字母被编码成1个字节，汉字通常是3个字节，只有很生僻的字符才会被编码成4-6个字节。如果你要传输的文本包含大量英文字符，用UTF-8编码就能节省空间：

因为 Python 认为 16 位的 unicode 才是字符的唯一内码，而大家常用的字符集如 gb2312，gb18030/gbk，utf-8，以及 ascii 都是字符的二进制（字节）编码形式。把字符从 unicode 转换成二进制编码，当然是要 encode。

想法不仅引导我们构造证明，还会引导数学家提出新的命题，发展新的理解，解决新的问题。这一部分是我们所知甚少的，也是目前科学所无法处理的。

每写一步有跳步或者过不去gap马上都会被计算机检查出来，要么补上这些gap完成证明，要么补不上

理论上可以，但是因为还是需要人来把证明内容输入给计算机，所以这就需要望月新一本人或者其他懂它证明的人学习使用辅助证明，把他的想法写成计算机可以理解的证明。

并非如此，事实上我们人能处理的理论基本上计算机都可以处理，当然使用的公理不同在某些特定的细节有所差别。

但是人思考的方式是共通的。并且计算机语言是一种比起自然语言更准确没有模糊性的语言，这其实有利有弊：严格的语言意味着人写证明不能再偷懒了，必须要准确的指出说的是什么，有时候会有些繁琐；好处不言自明，计算机可以验证是否正确，并且学习的人也可以通过查代码看每一步是怎么进行的避免跳步而不理解。某种意义上这种形式化的语言更适合数学，也很有趣。

它能做的是验证人写下来的证明，还不能像人一样智能得自己去推导新结论，也许遥远的未来可能会有有办法实现。

Android WebView is a system framework component.

Native code shared with WebView through a “Static Shared Library APK”: trichrome_library_apk

Multiple Chrome Targets

There are closed-source equivalents to these targets (for Googlers), which are identical but link in some extra code.

arm and x86 may optionally be used instead of arm64 and x64 for non-WebView targets. This is also allowed for Monochrome, but only when not set as the WebView provider.

run gclient sync to pull the new Android dependencies

.gclient

includes Chromium code while also using the system WebView

Android exposes assets and resources via AssetManager, but rather than use the AssetManager associated with the WebView APK Context that was created above, we instead add the WebView APK to the application‘s own AssetManager. This is important to ensure that resource references all work correctly: it’s possible for WebView resources (like XML layouts) to end up referencing app resources via themes, and so the resources have to coexist.

The dynamic sizing code was removed as it was complex and did not handle static shared library APKs correctly - the amount of space required in practise has not varied a great deal and hardcoded values suffice.

WebView did not normally depend on any library APKs in O, so this doesn’t usually cause an issue, but it‘s one of the reasons why it’s not possible to use Trichrome on O.

A side effect of createPackageContext is that ActivityManager is notified that the calling process has loaded the APK in question. This is used to decide which processes should be killed if that APK is uninstalled or updated, and thus when WebView is updated, all app processes that have loaded it are killed, and will use the new version if they are restarted.

but many of the downsides and complexities of Monochrome don't apply to Trichrome.

do not specify a different version. It is not necessary or beneficial to use an older SDK even if you are building a WebView for an older Android version - the built WebView is fully backward compatible, and building with older SDKs is not tested or supported.

prebuilt version

has a functional WebView for development and testing purposes.

a prebuilt WebView APK

Building WebView from the AOSP source tree (as earlier versions of Android did) is no longer supported.

This APK is preinstalled on the device and can be updated in the same ways as an ordinary application.

run their local build of Chromium

replace WebView in the system image for their Android device

system_webview_apk and trichrome_webview_apk use com.android.webview as their package name by default.

an interface between two binary program modules

Return a new Context object for the given application name. This Context is the same as what the named application gets when it is launched, containing the same resources and class loader. Each call to this method returns a new instance of a Context object; Context objects are not shared, however they share common state (Resources, ClassLoader, etc) so the Context instance itself is fairly lightweight.

mutually exclusive

Since Android Lollipop, WebView has been an updateable system component

the Android framework must load its native library.

The page will stay swapped until a new page fault on its virtual address happens, at which point the kernel will bring it back in main memory.

We call the amount a process' memory that is resident in physical memory its RSS (Resident Set Size). Not all resident memory is equal though.

Pages are organized in virtually contiguous ranges called VMA (Virtual Memory Area).
