其实abstract class和interface
都不过是一个单机的玩意
实际上后面对interface在不同虚拟机上的调用
搞出了rmi，rmi也不过是一个interface
然后rmi基础之上搞出了ejb
其实ejb说到底不过是一堆interface的定义
难道不是么？但是群众觉得太复杂
interface尚且如此，更何况是abstract class
说到底就是那个技术帖说的
当环境变化之后，你怎么可能要求别人的虚拟机跟你有同样的class？
这是一个joke
所以一个框架里面可能会出现abstract class，这没错
因为就是那么点人自己在搞，但是对外的接口
interface已经很离谱了，后来流行的趋势是用xml＋reflection来替换这些东西
这就是为什么spring能够火起来的原因
再后来，xml都嫌太复杂，因为纠错什么很不方便
于是用annotation来搞，其实reflection和annotation能做的
理论上abstract class早就能做了，问题在于
你怎么能要求别人去继承你的abstract class？

相比国内各大工业城市以含硫煤燃烧引发的大气污染（这也有个名字：伦敦型烟雾），
洛城的空气污染主要是含氮氧化物所至。因为这种微粒不比硫化物那样对大气中的水那

抽象类是专门用来被子类重载的，你可以定义一些方法在抽象类中，由各个子类实现，
这样你对子类的操作就方便多了。比如：
tGraph是抽象类，tLine、tCircle......等是他的子类
你可以把tLine、tCircle......作为tGraph来用，主要为了实现多态性
Abstract classes allow for default default function definition. This means
that whatever class extends the abstract class will have access to this. If
we have a base class where all the classes will perform the same function,
then we can define that in our Abstract class.

整体感觉就是：
1. 被拒多半还是实力问题+少许运气问题。onsite interview最好保证每一轮都不差（
哪怕都没有很突出），否则就很容易悲剧。所以还是得要多做题甚至多面试找感觉
2. 最有用的是lc+面经+大牛总结，面试时至少有30%-50%会遇到类似甚至一样的
3. bug free很难做到，也没啥必要. 之前有人说FB要求bug free被吓到了，但是感觉

发帖数: 10908 | 21 其实这个还是罗素理发师悖论，比较更隐蔽一点。。。这个里面的 deterministic-
abstract-machine 是利用时间轴上的不对称性（蓝眼 vs 棕眼）来 decidable
的。。。但这个需要所有 deterministic-abstract-machine 认知（对他们而言
的）标准时间，也就是时间轴上的“天数”(tick)是 countable and have same
(agreed) start point，（对于纯数可能就是 map 到 natural number set）
。。。满足这个条件就能 decidable（其中也包括所有人都是一样颜色的眼睛的
情况，tick 到第 n 天）。
所以那个外国游客，从香浓的信息论看，是提供了 tick 天数的 start point，
这样所有的 deterministic-abstract-machine 的时间轴能够校准到同一个
natural number set，从而使问题变成 decidable。
但是这归根到底还是罗素悖论，但这不在单个 abstract-machine 的 “极强逻辑”，

If its purpose is to decouple any units include-ing Foo.h and Foo's
actual implementation, the situation already justifies promoting Foo into
a higher level as abstract class such as IFoo.
So basically it is
abstract(IFoo) - semi abstract (Foo) - solid (Foo::Impl)
vs

PI写个abstract交给他。勤快的PM就自己动手把project summary改成abstract. |

Ada is a tank. A butt-ugly tank that never breaks down. People laugh
uncontrollably if you tell them you drive Ada, but really, do you want to be
driving a sports car in a war zone? [from Amit Dubey]

As with most "Why" questions about the design of C++, the first place to
look is The Design and Evolution of C++, by Bjarne Stroustrup1:
The curious =0 syntax was chosen over the obvious alternative of introducing
a new keyword pure or abstract because at the time I saw no chance of
getting a new keyword accepted. Had I suggested pure, Release 2.0 would have
shipped without abstract classes. Given a choice between a nicer syntax and
abstract classes, I... 阅读全帖 |

发帖数: 10908 | 48 这篇说得很好。我同意 Common Core Math 在 prealgebra 阶段的 over-explanation
可能 do more harm than good。
( 当然，我有 AMC 8 来平衡，我不是太担心。我们这边 accelerated path 里班的父
母们，估计也有办法。)
另外文章的下面这段，解释了为啥如果在没有跟传统数学 (比如 AMC 8) 配平比配好，
over-explanation 可能是 potential harmful，可能会 delay the leap to algebra
。(当然我个人不担心那个，我们还有 AMC 10，加个料就完事了。)

发帖数: 10908 | 49 这里还有一个人类语言的二义性的问题。。。也许 Piaget 老先生所说的 abstract
stuff 的意思，并不是黑格尔这种文学工作者所说的 abstract stuff 的意思。。。
也许 Piaget 老先生所说的 abstract stuff，指的是 be able mentally create
such object and process it mentally, wo/ the necessity to lay an
actual building-block or write it on scratch paper (当然是指 conceptual-
level 的认知事物，而不是人肉计算器搞竖式计算求结果）。。。而这个 object
本身完全可以是黑格尔文学工作者的 concrete object 而不是黑格尔的 abstract
object。。。就好比爱因斯坦一定能在脑子里 concretely 地构造/想象 concrete
的四维时空，以及进行 concrete 的计算或者估算或者目测。。。然后剩下的体力活
由秘书转交闵可夫斯基同志去办。。。

看我上面写的，“那两个就会被eliminated” 对于 deterministic-abstract-machine
不成立，因为对于 deterministic-abstract-machine 那个是 undecidable problem，
那两个会永远 “等待” 而不是 “先行自我了断”。
至于 nondeterministic-abstract-machine 并且输入还依赖其他 nondeterministic-
abstract-machine 的情况，除了理论计算科学系的疯子以外，一般人都不需要去
讨论，原因就是现实世界不可能存在，属于藤校疯人院话题。。。 |
