2014年中国程序员调查报告
2014年中国程序员调查报告 CodeForge网站最新发布了2014年第四季度《中国程序员调查报告》。报告里对程序员的年龄分布,地区分布,性别比例,使用浏览器种类,使用的编程语言等进行了调查、统计和分析。对从业人员及其他相关人员有很好的参考作用。 本调查报告所使用的数据,均来自codeforge.cn网站,集中了对全国100万程序员互联网行为的调查,分析以及投票统计。它清楚的显示出在程序员这个特殊的群体中,男性比例高达80%,女性仅占20%,他们具有明显的极客精神,喜欢使用Chrome浏览器(

zemax源码:
This DLL models an anamorphic aspheric surface.
This surface is essentially an even aspheric surface with different terms for
the x and y directions.
The sag is given by:
Z = ((CX*x*x)+(CY*y*y)) / (1 + sqrt(1-((1+KX)*CX*CX*x*x)-((1+KY)*CY*CY*y*y)))
+ AR*( (1 - AP)*x*x + (1 + AP)*y*y )^2
+ BR*( (1 - BP)*x*x + (1 + BP)*y*y )^3
+ CR*( (1 - CP)*x*x + (1 + CP)*y*y )^4
+ DR*( (1 - DP)*x*x + (1 + DP)*y*y )^5
Note the terms AR, BR, CR, and DR ... have units of length to the -3, -5, -7, and -9 power.
The terms AP, BP, CP, and DP are dimensionless.
The surface is rotationally symmetric only if AP = BP = CP = DP == 0 and CX = CY and KX = KY.

陆大富翁两周年了,自己学到了许多东西,尤其在自己喜欢的SQLSERVER方面吧。从论坛里一页一页的搜索自己喜欢的东西,并整理下来。并得到了许多大富翁的指导,在此表示感谢。并感谢周周共享论坛(www.pigtwo.com)给我一点空间,把自己喜爱的东西发表在上面。自己搜索了许多网站,整理了这个东西。里面可能有许多英文的东西,自己的翻译水平差,也没翻译。类别可能也分的不对,希望大家提出自己的意见,并共同探讨。更希望大家能找到自己有用的东西。
-Monopoly the second anniversary of the landing that he learned a lot, especially in their favorite bar SQLSERVER aspects. From the forum page of the search of their favorite things, and organize them. And a lot of Monopoly guidance grateful. And thanked the Week Week Sharing Forum (www.pigtwo.com) given me a little room to their favorite things published in the above. Own a lot of english sites, compiled this thing. There may be many things in English, their own level of poor translation, and there is no translation. Sub-categories may also be the wrong, I hope everyone make their own views and to explore. I also hope everyone can find their own useful things.
