告别微博
忽然觉得我应该远离新浪微博了。很久以前注明互联网砖家麦田老湿就曾经发表过关于社区的注明论断"所有的社区,都不过是扎堆,聊天,kill time"。按照这个特性区分,到目前为止我觉得我所蜷缩的社区就是QQ、和新浪微博。之前还有个人人网,后来我勇敢的告别了人人。现在QQ也处于半告别状态,3、5天上一次,看看各种同学、白痴、笨蛋群里的低能留言。
从新浪开始他们所谓的内测也就是众所周知的饥饿营销到现在14个月了,我看了一下我的第一条微博发布在2009年8月28日到现在基本上15个月。发布637条微博,吸引127头粉丝。每日花费在新浪微博上的时间也日渐增多,无论是打开firefox还是chorme,sinafox和fawave都第一时间蹦达出来,然后转贴、微观、kill time。
144个字的限制的确让信息传播的变得无比快速、便捷,但是也导致信息泛滥。除了我这样的闷骚男没完没了的看见好玩的东西一定转发,甚至恨不能直接发信息给别人之外还有另一帮暴露狂,恨不能几点几分在哪里上厕所都通过互联公布的透明人,还有各种花都往外冒的话痨。而大多数人都是这几种怪兽的混合体。每天普天盖地的信息汹涌而来,很有一些信息过载的压力感。到目前为止,Miniblog类站点的各种过滤器之中靠谱的还真不怎么多,新浪的方法就是分组,这真是个馊主意。因为无论你怎样分组,在靠谱的分组里都会出来毫无信息价值同时又跟你的生活毫不相关的打屁聊天的blog。在这种信息上浪费时间才是令人沮丧呢。
144个字的限制再让信息变得高度浓缩,毕竟你想把一件事情在144个字中说清楚是一件很有技术含量的浓缩工作。因此上,一部分人浓缩的很好,但是每天看到的更多的是一些操蛋结论。我依然认为,在信息传播效果上,最好还是博客。如果你想了解一个人,知道他最近正在读什么?想什么?甚至是他对世界,对人,对神的观点,最好的途径就是他的博客,而非他的微博。通过他的微博,你最多看到只不过是他只言片语的结论,这种结论总让人想起擅长断章取义、移花接木的心花射啥的。
这样一个即浪费时间,有扯淡低效的平台,So,以后长期驻留的还是俺滴blog和Google Reader

蒙牛已死
1. 尘埃落定之后,沸沸扬扬的圣元性早熟竟然变成这样的结局,果然不愧一片神奇的土地。
2. 当年蒙牛打造中国乳都、将牛奶变成运动产品甚至娱乐产品。初生牛犊,恐怕在贴切不过,锋芒毕露,一次次挑战了人们对牛奶的理解,演绎着战略对战术的完美胜利。
3. 可惜了,蒙牛终于暮气沉沉再不复当年锐气。据说,和公关公司合作,往对手身上扔屎以表明自己干净是国内口碑市场的通行做法。锋利少年终于变成了老态龙钟世故油滑的昏聩匹夫,除了严重同质化的产品线、毫无生机的市场策略,还有和其他竞争对手一样的庸俗战术,总之但求稳妥,再无早年前瞻而凶悍的战略。
4. 令人扼腕叹息的是,这次事件之后,蒙牛除了发布了一篇不疼不痒无关大局的声明之外还指出了伊利也用同样的方法攻击过蒙牛。这基本上相当于一个家伙被别人嘲笑屁股上有屎之后赶快趴到人家屁股上观察半天,宣布人家屁股上也有屎。对于高贵者而言,这毫无疑问是自降身价、自甘堕落,当然,蒙牛早已堕落。
5. 事实上,蒙牛最好的机会在三聚氰胺事件发生时。当时整个牛奶行业从上游到下游全线溃塌。其时,是整合上游资源,塑造全新牛奶生产方式,从而大幅度变革行业格局的最好契机,也是蒙牛占领上游资源的战略机会,只可惜一心求稳而在无进取意识的蒙牛人在小品演员牛根生的闹剧中闹腾了一把,而错失了最好的机会。
6. 今天蒙牛的表现只能说小富即安的蒙牛丧失了早些时候冒险家与挑战者的魄力,因此,无论再有多少次机会也不可能把握的住,而只能做些类似的拙劣表演。
7. 蒙牛已死。

'This Is Your Life' is one of the most popular programmes on British and American television. Every week a famous person is invited to a television studio, without knowing that he or she will be the subject of the programme. The compère meets the person outside the studio and says 'This is your life!' The person then meets friends and relatives from his or her past and present. Studio 4 is where the programme is recorded. The programme begins at eight o'clock. It's 6:45 now and the director is checking the preparations with his new production assistant (PA). The subject of tonight's show will be an actor, Jason Douglas. The compère, as usual, will be Terry Donovan.
Director: Let's just check the arrangements. We're bringing Jason Douglas here in a studio car—he thinks he's coming to a discussion programme! The driver has been told to arrive at exactly 7:55. Now, the programme begins at eight o'clock. At that time Jason will be walking to the studio. Terry Donovan will start his introduction at 8:01, and Jason will arrive at 8:02. Terry will meet him at the studio entrance ... Camera 4 will be there. Then he'll take him to that seat. It'll be on Camera 3. Jason will be sitting there during the whole programme. For most of the show Terry will be standing in the middle, and he'll be on Camera 2. The guests will come through that door, talk to Terry and Jason ... and then sit over there.
Director: Now, is that all clear?
PA: Yes ... there's just one thing.
Director: Well, what is it?
PA: Who's going to look after the guests during the show?
Director: Pauline is.
PA: And where will they be waiting during the show?
Director: In Room 401, as usual. Pauline will be waiting with them, and she'll be watching the show on the monitor. She'll tell them two minutes before they enter.
PA: I think that's everything.
Terry: Good evening and welcome to 'This is Your Life'. This is Terry Donovan speaking. We're waiting for the subject of tonight's programme. He's one of the world's leading actors, and he thinks he's coming here to take part in a discussion programme ... I can hear him now ... yes, here he is! Jason Douglas ... This is your life!
Jason: Oh, no ... I don't believe it! Not me ...
Terry: Yes, you! Now come over here and sit down. Jason, you were born at number 28 Balaclava Street in East Ham, London on July 2nd, 1947. You were one of six children, and your father was a taxi driver. Of course, your name was then Graham Smith.
Terry: Now, do you know this voice? 'I remember Jason when he was two. He used to scream and shout all day.'
Jason: Susan!
Terry: Yes ... all the way from Sydney, Australia ... She flew here specially for this programme. It's your sister, Susan Fraser!
Jason: Susan ... Why didn't you tell me ... oh, this is wonderful!
Terry: Yes, you haven't seen each other for 13 years ... take a seat next to him, Susan. You started school at the age of five, in 1952, and in 1958 you moved to Lane End Secondary School.
Terry: Do you remember this voice? 'Smith! Stop looking out of the window!'
Jason: Oh, no! It's Mr. Hooper!
Terry: Your English teacher, Mr. Stanley Hooper. Was Jason a good student, Mr. Hooper?
Mr. Hooper: Eh? No, he was the worst in the class ... but he was a brilliant actor, even in those days. He could imitate all the teachers?
Terry: Thank you, Mr. Hooper. You can speak to Jason, later. Well, you went to the London School of Drama in 1966, and left in 1969. In 1973 you went to Hollywood.
Terry: Do you know this voice? 'Hi Jason ... Can you ride a horse yet?'
Jason: Maria!
Terry: Maria Montrose ... who's come from Hollywood to be with you tonight.
Maria: Hello, Jason ... it's great to be here. Hello, Terry. Jason and I were in a movie together in 1974. Jason had to learn to ride a horse ... Well, Jason doesn't like horses very much.
Jason: Like them! I'm terrified of them!
Maria: Anyway, he practised for two weeks. Then he went to the director ... it was Charles Orson ... and said, 'What do you want me to do?' Charles said, 'I want you to fall off the horse'. Jason was furious. He said, 'What? Fall off! I've been practising for two weeks ... I could fall off the first day ... without any practice!'

第一章 基因载体概论
第一章 基因载体概论
第一节 基本概念
Gene manipulation:将生物的某个基因通过基因载体运送到另一种生物的活性细胞中,并行使正常功能从而创造新品种或新性状的遗传学技术。
典型的Gene manipulation:在体外将目的DNA+载体DNA=复制子;复制子在宿主细胞(生物)中复制,转化或转染宿主细胞、生长和筛选转化子,无性繁殖使之克隆;利用克隆分子导入适当的表达体系,是重组基因在细胞内表达,产生特定的基因产物。
嵌合DNA(重组DNA):基因工程中内、外源DNA插入载体分子所构成的杂和分子
Molecular cloning(gene cloning):构建重组分子的过程,重组分子无性繁殖的过程。
Gene manipulation的目的:1、克隆保持基因片段;2、高效表达特定基因序列;3、调整生物学性状。
Gene manipulation的三个关键部分:目的基因、宿主、载体基因
第二节 载体基因的一般特性
载体:具有将外源目的DNA导入受体细胞,并能自我复制和增殖的工具
载体的特性包括:1、独立的复制子;2、尽可能小的分子负载较大的DNA;3、多克隆位点和选择行标记;4、插入片段对载体和宿主无害:既包括插入部位无害也包括片段长度无害。
第三节 基因载体分类
一、病毒载体和非病毒载体
1、 病毒载体
天然病毒必须经过必要改造才能成为载体。病毒载体转染率高、存在免疫原性、存在与宿主细胞整合的潜在危险、对插入DNA长度有限制。
从天然病毒变成病毒载体的改造包括:可以携带外源基因并能包装成病毒颗粒;可以介导外源基因的转移和表达;改造后载体不具有致病性。
病毒基因组包括
(1)、编码区
产生结构蛋白和非结构蛋白;可分为必需基因和非必需基因
(2)、非编码区
顺式作用元件
可包括:重组型病毒载体和无病毒基因的病毒载体
2、 非病毒载体
2.1、质粒载体
2.2、噬菌体载体
2.3、cosmid 载体
2.4、人工染色体
二、克隆载体和表达载体
1、 克隆载体:
保存基因为主要目的载体,主要考虑载体容量、稳定性、效率、对序列偏好性、操作的方便性。
2、 表达载体
在克隆载体的基础上在多克隆位点附加表达调控序列以表达外源基因,或者在一个可表达报告基因的上游附加多克隆位点用于检测顺势元件功能。包括翻译性表达载体、转录性表达载体、报告性表达载体。
三、游离载体和整合载体
四、穿梭载体
