How to Fix Acrobat X Pro Won’t Open

Posted on December 28th, 2013 Sean Add comments

Acrobat X Pro won’t start on Windows 7 (64-bit) recently. It just doesn’t respond whether I try to open PDF files with it or double-click to start the program. I am pretty sure I DID activation while I install it. After some researches, realized the reason might be I did NOT sign in. (how stupid software!!)
I did the following, and it does the job for me:
1. Delete the file “C:\Program Files (x86)\Common Files\Adobe\Adobe PCD\Cache\Cache.db”
2. Open the program
3. Sign in with your username/password (if you don’t have, apply one)
4. Acrobat will be back
Windows

最完整版眼保健操

Posted on August 14th, 2013 Sean Add comments

     刚从网上找到了最完整版的眼保健操，此版本终于成功包括“伟大领袖毛主席…”的开头。
     百度了一下，此保健操源于1961年北京市教育局在全市范围的中小学生中进行的一次视力普查。由于中小学生的近视率随着年龄增长明显增高，北京市教育局分管学生健康工作的严亦柔，与市防疫站（现北京市疾病预防控制中心）的于凤翥和陈永馥两位老师，决定自行组成一个“工农兵协作组”，并立即着手开始了在全市中小学范围内的预防近视工作。她们打听到北京医学院（现名北京大学医学部）体育教研组刘世铭主任曾自创了一套眼保健操，这套眼保健操共8节，不但有文字说明，还配有穴位图。在刘世铭的指导下，她们3人很快便熟练掌握了穴位和手法。，并与1963年首先在北京第28中学进行试点。同年，北京市景山学校、北门仓小学等学校开始试做这套眼保健操。
     随着1966年“文革”的来临，学校停课，老师回家，眼保健操也就半途“夭折”。于凤翥等3人小心翼翼地保存着手绘图解，静静地等待。直到1972年，当学校恢复正常上课了，于凤翥等人才将倾注了多年心血的眼保健操又搬了出来。为了更便于操作和推广，于凤翥等人又商量着把眼保健操制成唱片，同时打算再印一批眼保健操的标准穴位挂图。为了实现这一愿望，她们开始在全市范围内寻找模特，挑来选去，最后敲定了北京市光明小学五年级的一名姓刘的女生，她看上去乖巧伶俐，模样长得漂亮可爱，眼睛大而明亮，完全符合标准。挂图的模特定了，接下来，她们又从首都体育师范学院找了一位声音甜美的女生喊口令，又请中国唱片社给灌制了唱片，配乐用的是民乐。
     由于使用频繁，许多学校的眼保健操的唱片出现了磨损，而原先的制作单位又是一次性生产的，没有余存。于是，于凤翥等人各显攻关才能，最终敲定了由解放军军乐团作曲，总政歌舞团伴奏，最后在农科院附近的一个录音棚里完成了制作。这次发行的是盒带，伴奏音乐没有用上次的民乐，而是使用了沙锤等打击乐器，这样会更加突出节奏感，听起来比前一个版本要好听多了。于是，第二套眼保健操就这样诞生了，这5节操从1972年起推行，后又改为4节，延续至今。

Predicates in Lambda Expression for Entity Framework Code First

Posted on July 24th, 2013 Sean 1 comment

If I have 2 entities of “People” and “Car”, and “1” People can have “Many” Car, my code first class could be like below:

public class People
{
	[key]
	public int ID { get; set; }
	public string Name { get; set; }
	
	public virtual ICollection<Car> Cars { get; set; }
}

public class Car
{
	[key]
	public string VIN { get; set; }
	public string Maker { get; set; }
	public int OwnerID { get; set; }
	
	[ForeignKey("OwnerID")]
	public virtual People Owner { get; set; }
}

public class People

{

[key]

public int ID { get; set; }

public string Name { get; set; }

public virtual ICollection<Car> Cars { get; set; }

}

public class Car

{

[key]

public string VIN { get; set; }

public string Maker { get; set; }

public int OwnerID { get; set; }

[ForeignKey("OwnerID")]

public virtual People Owner { get; set; }

}
