backend language of choice# Programming - 葵花宝典

孩子刚满七岁近视就已经300度。作为家长很痛心,太大意了,已经发展到这种程度才
发现。想让孩子休学一年,不学习,到处走走,看视力能否有所恢复。但医生说没用。
最后可能还是要配副眼镜,至少控制住,防止近视继续急剧恶化。
两个问题请教:
一、关于验光结果
孩子暑假回国,做了1%阿托品散瞳(就是连续点三天眼药,第四天验光,三星期才能恢
复的那种),分别在北京两家正规医院验了光。以下是结果:
医院1:
右眼:球镜 -3.00, 无散光
左眼:球镜 -2.75, 散光 +0.25, 轴位120
医院2:
右眼:球镜 -3.00, 无散光
左眼:球镜 -2.25, 散光 -0.50, 轴位15
两家医院右眼结果无差异,左眼不同。一家医院给了较深的球镜度数和正散光,另一家
给了较浅的球镜度数但负散光。我在网上查,得知正负散光与球镜度数及散光轴位之间
有个换算关系,但具体怎么回事看不太懂。不知道这两种结果是否实际上差不多。如果
配眼镜,按哪种配比较好?
如果有懂视光学的人,能否帮忙解释一下。十分感谢!
二、我知道近视眼轴已经相对变长,基本不可逆。孩子又处在成长阶段,眼轴还在长,
所以近视很容易发展。但是,正是由于孩子还在长,如果完全脱离视近环境,眼睛有没
有可能朝着近视缓解的方向得到一定程度的修复。大家有没有听说,谁家孩子近视,家
长带着他四处游玩,不看书、电视、电脑什么的,最后视力改善的?
谢谢!

试了很多次都不成功,好像这个连接 http://shanghai-ch.usembassy-china.org.cn/forms.html 不work.有没有好心人能给个上海在线申请表格的链接。父母来美探亲签证,除了这个DS-160以外,还要填什么表吗?以前好像有157,156 表之类的。

这个卖家号称是在新加坡,ID: CHENYUHUA2007, 他贴了一个梅型张和梅无齿的卖贴
。大家看看有没有问题。
http://www.ebay.com/itm/China-C94-Mei-Lan-Fang-MS-and-Imperf-se
我查了一下他的其他ITEM,还有一套大龙宽边。我曾经被一个北京叫Yangyuhua 的骗了
,卖我一张假的大龙5分银宽边,一张假猴票,一张假的世乒赛型张。后来通过信用卡
索赔回来,他在EBAY上的ID也先是改了,后来被停了。
现在看来大家警惕性都提高了,这些人大有转移阵地,到其他国家的嫌疑。请问,在
EBAY上他们是如何能更改LOCATION的? 我觉得还是那么一些人或团伙在兴风作浪。
大家一块讨论一下。

for consumer web/mobile, I really only care about library support more than
anything else for backend language. That makes java my first choice, then
python comes to second. That is also why i wont use something like node for
another three years.

关于散光,有一种可能两个结果都对。在不同轴位上作远视或近视散光矫正,可能达到
同样的效果。不过你需要直接跟专业验光配镜师确认。

可以,最多6000 收入限制为66000 for single. 59.5 岁之后才可以正常取出来,按收
入交税。提前取有PENALTY.

first criteria, no dynamic type language
second choice, library.
a simple case, if someone make change to some API in library, the problem
won't be found until you run if it's dynamic type. but for static language,
most problem and client code change can be found by compiler.

401k is employer sponsored plan, you can have your own IRA as showed above

protect your dependencies by unit test, unit test is your documentation and
guard against api change.
for dynamic type language, unit test is integral part of the code base.

static language and dynamic language have different mind sets.
Scala currently has experimental macro that is as powerful as Lisp (Can
dynamically change your program in ANY way), they plan to ban it and allow
you only use macro that does not violate type check.

The nature flaw of dynamic languages can be compensated by automated tests.
While I don't prefer them in backend, I won't rule them out. There can be
good use cases.

compensation will be getting much smaller once you have a relatively large
system. automated tests are not the solution to everything.

With SOA, a single service should never go very large, or it's not done
right.
