linq 是语言层面的。web form 也好, mvc 也好, linq 都是可以用的。当然ef 没有
linq 没法用。
jsp, php, ruby, web form, mvc都是一个目的:生成html,放到http里通过internet
送给client。
web form 的问题是code behind容易搞的太臃肿,一旦加入了ui logic,里面的
business logic通常不能reuse, unit test也不好做。
mvc 强迫大家把presentation 的logic 同business logic 分开。 web form 也是可以
mvc的。mvc framework最开始也可以用code behind, 似乎到了final release阶段才去
掉。 mvc的controller还可以直接做 restful api, mvc4的web api 更是发扬光大。
code reuse 和 unit test要容易得多。

Stripes is the best action based framework, but I think component
based framework is the future. All action based frameworks have
difficulties in
1. Stateful wizard type applications, hacking hidden fields and session
isn't really fun.
2. Module reuse. JSP is not really great for reuse. JSP, with all the
EL in it, is against MVC pattern, EL is logic, and you have logic in view.
Other scripting templates share similar problems.

Most programmers would have experiences of creating bad designed software.
But what is a "bad design"?
1. It is hard to change because every change affects too many other parts of
the system.
* Rigidity
2. When you make a change, unexpected parts of the system break.
*Fragility
3. It is hard to reuse in another application because it cannot be
disentangled from the current application.

right they should be lists. So even these lists take a huge ammount of
memory, they will be kept in memory for potential future reuse? This seems
not optimal since the probability that a huge list (consist of huge strings)
will be reused should be very low. In my case they actually eat up huge
ammount of memory. Is there any way to explicitly free the memory of these
lists?

来自主题: Programming版 - 一个c++ constructor的问题, thanks
I think it has to do with the lifetime of an object:
In [basic.life]
"""
The lifetime of an object of type T ends when:
--if T is a class type with a non-trivial destructor (_class.dtor_),
the destructor call starts, or
--the storage which the object occupies is reused or released.
"""
Calling placement new on 'this' reuses the storage for another
object, thus the lifetime of the original object ends. Accessing
members of the original object would result in undefined behavior.

来自主题: Programming版 - go也是三种paradigm混合的语言

OO
有时间多聊一点。我的理解,static methods是workaround,根本原因是OO不承认
function的存在。否则static method理应是function。不知道大牛你们是如何把
static methods映射到现实世界的。
方法封装的问题是code reuse带来困难。所以OO出现了inheritance,又造就了更强的
耦合。所以更好的解决办法是用interface和function来解决。这样就可以decouple了
,而且code reuse也非常简单,现在Java明显就是这个方向发展的。当然你可以封装
methods,但是这可能不是普遍情况。

来自主题: Programming版 - tf还是很混乱
tf的机制是这样的:一个variable声明到什么设备上,就定在什么设备上了。
然后声明在别的设备上的操作要用这个variable会自动拷过去。
所以多gpu的机制就是
- 在CPU或者第一个GPU上构造网络。所有的参数都会分配到这个设备上。
- 设置variable scope reuse
- 然后在别的设备上构造同样的网络。op会重新命名,但是所有的variable会reuse,
也就是引用第一个设备上的那套参数。
- 所以其实所有可训练参数只有一个版本。更新的时候也只要更新这个版本就行。
- 但是gradient所有的GPU都有自己的版本,需要merge。
batch_norm有moving average和variance。这个不是用gradient训练的。
我也不知道是什么机制。其实把graph打印出来查看可以看到具体情况。

中国高速发展的经济背后,环境问题一直如芒在背,已经渗透到生活的方方面面。看得
见的是雾霾,但还有更多看不见却又和生活息息相关的环境问题,比如垃圾围城。
垃圾围城是全球性难题,随着经济发展和消费主义的兴起,越来越多的生活垃圾被不断
制造出来,为了保证城市的正常运转,大量的垃圾被运往城乡集合部,对城市形成包围
之势。根据住建部2013年的数据,我国有三分之一以上的城市被垃圾包围,城市垃圾堆
累计侵占土地75万亩。王久良2010年拍摄的纪录片《垃圾围城》,通过对北京周边几百
座垃圾场的调查,用镜头记录了北京的垃圾围城现象。
面对垃圾围城的严峻形势,垃圾分类被普遍认为是解决该问题的重要步骤。2016年9月
,发改委和住建部联合发布的《“十三五”全国城镇生活垃圾无害化处理设施建设规划
(征求意见稿)》将“分类回收,促进利用”作为基本原则。同济大学循环经济研究所
教授杜欢政认为,要消除垃圾围城的隐患,首先要从改变公众观念做起,特别是要推进
垃圾分类。浙江省公共政策研究院副院长蓝蔚青也认为政府部门要通过顶层设计让全民

垃圾产业已经成为朝阳产业了
青年时报
有媒体报道称,中国1/3以上的城市均深陷垃圾围城困局。另有数据指出,现在中国除
县城之外的668个城市中,有2/3的城市处于垃圾包围之中,1/4已经无垃圾填埋堆放场
地。全国城市垃圾堆存累计侵占土地超过5亿平方米,每年的经济损失高达300亿元。
与此相对应的,是仅为50%左右的城市垃圾处理率。一些早早兴建的垃圾处理设施,在
城市的快速膨胀中,也迅速陷入超负荷运转的窘境。如承担广州市9成垃圾填埋量的兴
丰垃圾填埋场,由于垃圾增幅过快,将于2012年被填满,而北京市的所有垃圾填埋场也
将在5年内饱和。 如今,面对如何拆除围城垃圾这枚巨型“炸弹”的问题,许多城市的
答案又从填埋变成了焚烧。
2000年以来,国家陆续发布了一系列鼓励垃圾焚烧产业发展的政策,目前我国共有62个
垃圾焚烧厂。放眼全国,已经拥有焚烧炉的城市包括哈尔滨、大连、天津、北京、上海
、深圳、宁波、温州、武汉、重庆、广州、太原……这个名单还在不断增加中。
