[2007.06.08]College Entrance Examination

By dch1 in Just Notes No Comments

Today is the 2nd day of the college entrance examination.And it is also an anniversary of my college entrance examination.Being honest,I think the life was unforgettable when I was in 3rd grade of the senior middle school.Everyear,many students got liberation even if there are only two temporary freedom.Maybe they will participate in the university life in September.

For me,I think the topic of the composition will got the lion difficult among all version of the otner places.At first,the paper gave a poem to be a guidance.The expers said that it is not easy for a candidate to make an argumentation.It likely that the candidates should write a story or a description.It is extremely easy for the candidates to run out of the topic.

I read an article I written on June,7th,2006.I was so glad that I can feel the feelings even if it has passed for one year.I need to continue writting my weblogs.It is not only for others,but also for me.

I will have IELTS test next month(July,7th).Good luck for me!

[2007.06.03]A remarkable day for my E-life

By dch1 in Just Notes No Comments

I bought a new host on Friday.It is much cheaper than China hosts.And I got an extra domain which is selected “bjdch.org”.It is stand for Beijing DCH Studio–An organization for computer technology.

At the first time,I want to get a domain name like “dominic.com”.Because my english name is Dominic-Our foreign english teacher gave me that name.But the domain has been registered by others and I cannot find a suitable new domain name except “bjdch.org”.So I choosed it.It sounds great!

But I was frustrated by the transportation from old one to the new one.Because I only knew little about the Mysql Databases.I searched the Internet for help.

The main difficulty is the domain name.Because I used to make “w t . b j d c h . c o m / b l o g” and “w w w 1 . b j d c h . c o m” for my blog address.I want to change them into “blog.bjdch.org”.It nees knowledge about the syntax.I tried many times.At last, I won!

It needs four syntax:

UPDATE `_snapshot_recover_wp_posts` SET `guid` = replace (`guid`,’w t  . b j d c h . c o m / b l o g’,’blog.bjdch.org’) WHERE `guid` LIKE ‘%w t . b j d c h . c o m / b l o g%’
UPDATE `_snapshot_recover_wp_posts` SET `guid` = replace (`guid`,’w w w 1 . b j d c h . c o m / b l o g’,’blog.bjdch.org’) WHERE `guid` LIKE ‘%w w w 1 . b j d c h . c o m / b l o g%’

UPDATE `_snapshot_recover_wp_posts` SET `post_content` = replace (`guid`,’w t . b j d c h . c o m / b l o g’,’blog.bjdch.org’) WHERE `guid` LIKE ‘%w t . b j d c h . c o m / b  l  o g%’
UPDATE `_snapshot_recover_wp_posts` SET `post_content` = replace (`guid`,’w w w 1 . b j d c h . c o m / b l o g’,’blog.bjdch.org’) WHERE `guid` LIKE ‘%w w w 1 . b j d c h . c o m / b l o g%’

This host contains a powerful control panel.Here is the main pages of the panel.

By dch1 in Just Notes 2 Comments

Today is Sunday . This week is more busy than passed weeks . On Monday , when I went to the libruary , the administrator rufused me to entered the building . Because the Student Card is invalid . I was so depressed that I did not want to read a word in the classroom because I used to study in the libruary every evening . Maybe that is why I am writting weekly diary now .
I got flu this week . I think I need to take more physical exercise . And my father was sent to the HuiMin Hospital because of the fever . He has been fever for more than three weeks . Now he feels better now in the hospital .
Yesterday , I converted all the Cambridge Ielts(tape edition) into digital audio(128Kbps 44Hkz MP3 files) . It was really a hardwork . You need run all the tapes . But I was glad because it is easy to the teachers and our classmates to use it .

Spring Festival

By dch1 in Just Notes No Comments

The Spring festival is quite busy for me . Because I opened a shop on Taobao . I put some useless things on it . The most expensive one is Kodak V705 digital carmera . And it is marked 1,800 RMB . I stayed at home and kept online everyday . Many customers asked for it . But they wanted to get on a cheap price . But , in the fact , my carmera has the lowest price on Taobao . I refused to bargain at last .

One day , when I was available , a new customer ID asked me for some details . But I noticed that he really wanted to buy the carmera . Our trade has been successfully finished .

Not only did I sold a digital carmera , but also I sold out other things . I do love E-Business .

熊猫烧香

By dch1 in Just Notes No Comments

从去年十月份开始,直至今日仍令上百万用户头疼的熊猫烧香病毒,其作者已于2月12日被抓获归案。

我也曾经在自己的“肉鸡”上,试验过这个病毒,这个病毒毒性很强,一旦运行之后,不但摧毁文件,而且还试图在网络上传播。

天网防火墙在的拦截记录:

[16:55:24] 192.168.1.2试图连接本机的CIFS[445]端口,
TCP标志:S,该操作被拒绝。

路由器拦截记录:

394  1829523:IP绑定冲突: LAN 中MAC地址为 00-XX-XX-XX-XX-XX 的主机尝试使用IP地址 192.168.1.10
395  1829528:IP绑定冲突: LAN 中MAC地址为 00-XX-XX-XX-XX-XX 的主机尝试使用IP地址 192.168.1.10
396  1829534:IP绑定冲突: LAN 中IP地址为 192.168.1.10 的主机被攻击了 270 次

他甚至想利用更改IP的方法达到网络瘫痪的目的。幸亏我开启了ARP绑定,才幸免于难。

以下是病毒作者开发出的专杀工具:

xmkill.jpg

以下是网友的恶搞:

    ●“你这个无情的熊猫,你真是太自私、太无情、太残忍了!你就为了自己一时的满足,你就忍心让我连网也不能上了吗?天哪!你竟是如此的无情、残酷!你伤了我的心!你深深地伤害了我的心,你知道吗?我的心在流血,你知道吗?我恨你!我恨你!我恨你!我恨死你了!你走,我不要再见到你!我要快乐的生活,我要快乐的上网!你这无情的小东西,天哪,你怎么是这样的残忍?你怎么能这样对我?我究竟做错了什么?我做错了什么?你告诉我,我究竟做错了什么?你要这样惩罚我?求求你,你告诉我!你告诉我啊!”

  ●由《满城尽带黄金甲》主题曲《菊花台》改版的“熊猫烧香”极为形象地表现了中毒者的无奈。“你的泪光,柔弱中带伤。满屏的熊猫香,删除过往。熊猫猖狂,点上三根香,是谁在电脑前冰冷地绝望。猫慢慢拜,暗黄色的香。我瘫坐椅子上,精神错乱,路在何方,谁为我思量,冷风吹乱憔悴模样。熊猫拜,三根香,你的笑容已泛黄。重装又重装,我心里在发慌。江民杀,瑞星除,你的影子剪不断,徒留我在机旁神伤。”

  ●黄健翔在世界杯上的“惊世一吼”,已经成为了专用的话语方式。在“熊猫烧香”引发的创作热潮中,也出现了很多个熊猫烧香版的黄健翔语录,最经典的一个版本如下:

  “防火墙,过它,好的,进去了,用户在操作。哎、发作!发作!发作!熊猫烧香立功了,熊猫烧香立功了!不要给杀毒软件任何的机会。

  “伟大的熊猫烧香!它继承了中国病毒的光荣的传统。卡巴斯基、瑞星、江民科技在这一刻病毒附体,熊猫烧香一个病毒,它代表了电脑病毒悠久的历史和传统,在这一刻它不是一个病毒在战斗,它不是一个病毒!

  “熊猫,熊猫面对这个机会。它面对的是全世界电脑病毒的目光和期待。杀毒软件曾经在这台机子上杀过不少病毒,熊猫应该深知这一点,它还能够微笑着面对它面前的实时监控吗?10秒钟以后它会是怎样的下场?”

床前明月光,熊猫在烧香 
专杀杀不尽,两眼泪汪汪 
熊猫烧香是瑞星江民金山的财神爷,是修电脑的衣食父母
 
我是周杰伦,我也中了熊猫烧香 
 这病毒真叼,还我这几天都没点灵感 
 
我是姚明 最近本来伤病停赛够倒霉的啦~ 天天看A片发泄
结果出来个熊猫把硬盘200g毛片给办了! 整整下载了一个赛季的a片啊
郁闷!!!!!!

我是刘德华,这病毒把我的头发都给整秃了

我是赵本山!哎呀妈呀!这病毒玩意,贼厉害了!整的我都脑血栓了!
我是外星人,这个病毒传到外星球去了,唉,害得我给地球公安天天打长途,贵啊!

实际上,我觉得,熊猫烧香病毒带给我们的教训应当是更加重视网络安全,就像病毒作者在专杀工具里面提到的:熊猫走了,是结束吗?不是的,网络永远没有安全的时候,或许在不久,会有很多更厉害的病毒出来!所以我在这里提醒大家,提高网络安全意识,并不是你应该注意的,而是你必须懂得和去做的一些事情!

I was busy these days . Because I go to Golbal IELTS School everyday . And there are some unpleasant happend . I found a reading course but it was not suitable for me . So I asked the school administrator to change into another reading class . The administrator didn’t agree . So I complained my suffering by phone . At last , they admitted me to change it .

There are many people complaining that they are not satisfied with the Golbal IELTS School . For example , 1 2 .

=================================

I had a new-year-concert DVD . I bought it on Taobao .

2007wyn.jpg

It is not expensive (only in 20 Yuan) . I would like to write something down about it in the spring festival .

=================================

The spring festival is comming . Best wishes for everyone , not only the people who gives me help . And I have some small gift to you .

Please download as quickly as possible . It will not available soon . Because I put them on old space which is going to expire soon .

好久没有更新博客了,所以就不能叫做DIARY了,更不能叫做隔日记。究其原因,可能是因为懒惰的缘故:-)。

OK . Let’s start !

I have posted some second-hand on the flea.zol.com.cn for several days . I have selt two of them till now . One is Usb-disk which is broken , the other is a laptop memory . I got 150 RMB back from the bargain . I was so excited because I sold out some useless things .

I re-installed Windows system these days . I installed Vista on notebook . I do love the theme of the new operating system . Here are some pictures I took .

I went to the BMCC to get an IC card . It cannot withdraw the money because it is a gift card .

ic card1.JPG ic card2.JPG

I am often interested in IC cards . The full name of IC card is Integrated Circuit Card . I found a brief induction on the Internet .

非接触式IC卡简介
  非接触式IC卡又称射频卡,由IC芯片、感应天线组成,封装在一个标准的PVC卡片内,芯片及天线无任何外露部分。是世界上最近几年发展起来的一项新技术,它成功的将射频识别技术(也就是RFID)和IC卡技术结合起来,结束了无源(卡中无电源)和免接触这一难题,是电子器件领域的一大突破.卡片在一定距离范围(通常为5—10mm)靠近读写器表面,通过无线电波的传递来完成数据的读写操作。
  1.非接触性IC卡与读卡器之间通过无线电波来完成读写操作。二者之间的通讯频为13.56MHZ。非接触性IC卡本身是无源卡,当读写器对卡进行读写操作是,读写器发出的信号由两部分叠加组成:一部分是电源信号,该信号由卡接收后,与本身的L/C产生一个瞬间能量来供给芯片工作。另一部分则是指令和数据信号,指挥芯片完成数据的读取、修改、储存等,并返回信号给读写器,完成一次读写操作。读写器则一般由单片机,专用智能模块和天线组成,并配有与PC的通讯接口,打印口,I/O口等,以便应用于不同的领域。
  2. 非接触性智能卡内部分区
  非接触性智能卡内部分为两部分:系统区(CDF)用户区(ADF)
系统区:由卡片制造商和系统开发商及发卡机构使用。
用户区:用于存放持卡人的有关数据信息。
  3. 与接触式IC卡相比较,非接触式卡具有以下优点:
  ⑴可靠性高非接触式IC卡与读写器之间无机械接触,避免了由于接触读写而产生的各种故障.例如:
由于粗暴插卡,非卡外物插入,灰尘或油污导致接触不良造成的故障. 此外,非接触式卡表面无裸露芯片,无须担心芯片脱落,静电击穿,弯曲损坏等问题,既便于卡片印刷,又提高了卡片的使用可靠性.
  ⑵操作方便
  由于非接触通讯,读写器在10CM范围内就可以对卡片操作,所以不必插拨卡,非常方便用户使用. 非接触式卡使用时没有方向性,卡片可以在任意方向掠过读写器表面,既可完成操作,这大大提高了每次使用的速度.
  ⑶防冲突
  非接触式卡中有快速防冲突机制,能防止卡片之间出现数据干扰,因此,读写器可以”同时”处理多张非接触式IC卡.这提高了应用的并行性,无形中提高系统工作速度.
  ⑷可以适合于多种应用
  非接触式卡的序列号是唯一的,制造厂家在产品出厂前已将此序列号固化,不可再更改. 非接触式卡与读写器之间采用双向验证机制,即读写器验证IC卡的合法性,同时IC卡也验证读写器的合法性.
非接触式卡在处理前要与读写器之间进行三次相互认证,而且在通讯过程中所有的数据都加密.此外,卡中各个扇区都有自己的操作密码和访问条件.
  接触式卡的存储器结构特点使它一卡多用,能运用于不同系统,用户可根据不同的应用设定不同的密码和访问条件.
  ⑸加密性能好
  非接触式IC卡由IC芯片,感应天线组成,并完全密封在一个标准PVC卡片中, 无外露部分。非接触式IC卡的读写过程,通常由非接触型IC卡与读写器之间通过无线电波来完成读写操作。
  非接触型IC卡本身是无源体, 当读写器对卡进行读写操作时, 读写器发出的信号由两部分叠加组成:一部分是电源信号,该信号由卡接收后,与其本身的L/C产生谐振,产生一个瞬间能量来供给芯片工作。另一部分则是结合数据信号,指挥芯片完成数据、修改、存储等,并返回给读写器。由非接触式IC卡所形成的读写系统,无论是硬件结构,还是操作过程都得到了很大的简化,同时借助于先进的管理软件,可脱机的操作方式,都使数据读写过程更为简单。
   耐高温感应卡
  为满足实际应用需求,我们不断开发适应特殊应用环境的高性能感应卡,在抗高温、抗折和采用环保材料方面,我们采用进口耐高温材料复合而成,具抗高温、耐折的优越特性,在车头高温曝晒不易变形,不影响功能特性,配合我们的感应卡读写器,广泛应用在高速公路收费和小区管理。

ic card3.JPG
    我们的市政公交一卡通就是因为这个原因而选择用非接触式卡的。
  公交车、地铁上下班非常拥挤,试想一下,如果在上班高峰期,每个人拿着卡往读卡器里插,你的卡还没有拔出来,后面的人就开始挤你,卡很可能就断在读卡器里啦。使用非接触式IC卡,这个问题就能迎刃而解了。拿着卡一碰读卡器,嘀的一声,不用任何操作,就可以上车了。
  不少停车场也开始用非接触式卡作为计时凭证了。车辆在出入停车场时,将卡放在出入口的读卡器感应区内,读卡器就会识别出这张卡,然后与电脑内部的记录对照,判断出停车时间等信息。
  还有学校、单位里面也大量使用这样的卡。这是一张校园卡,无论是去食堂吃饭、图书馆借书,还是打热水、洗澡,只要用这一张卡轻轻一刷就OK了,学生就不用整天带着学生证和钱在学校里跑来跑去了。
  而单位的门口用非接触式卡,能收集每个人出入的信息,作为考勤的依据。
  我们的第二代智能身份证也属于非接触式IC卡。以前的身份证都是手写的或打印的,容易伪造,有关部门要查一个人的资料要把身份证号码输入到电脑里,再与数据库里的信息核对。而第二代身份证里装上了芯片,只要把卡靠近读写器,就能读出身份证里的信息。不法分子如果造假,只能做出卡的外观,做不出里面的芯片,在扫描器上一放,身份证真假立现。
  虽然非接触式卡使用起来方便,但也有美中不足的地方。
  (容量上,接触式卡是去年世界上最大容量的卡现在已经达到了1M字节,而非接触式卡最大容量,就比如说象咱们北京市市政交通一卡通这个卡,我们发行这个卡就是4k字节,容量是没法比的)
  虽然说理论上非接触式卡可以在15厘米内读出卡内信息,但是制卡商在生产时是可以根据使用环境调距离的,比如停车场的卡就可以设定得远一些,手潮的司机也不用怕够不着,而公交卡、食堂卡可以设定得近一些,你只有贴在读卡器上边才能把钱刷走。
  另外就是读卡的时候读卡器和卡内的芯片会做双向验证,互相认识才能沟通信息,而且每个芯片的确认号是在生产时就固定下来的,没有重样的,你读出卡里的信息也没法伪造。
  (非接触卡是一个趋势,因为非接触卡操作是非常方便的,IC但不可能是完全被取代的,因为非接触式卡的成本是很高的。除非芯片供应商来降低成本,能和接触式卡的价格相当了,那有可能会全面普及非接触式卡。)

Today I had a new book in IELTS class . There are many classification exercises in the books . Such as , Education , The media , work , Money & finance and so on .
