[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.

[2007.03.26~2007.04.01]Weekly Summary

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 .

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 .

Yesterday , I had tried to install Windows 2000 Profressional . Because the Intellgent Battery Charger could not be run in Windows 98 . Here are some shots .

2000-1.JPG 2000-2.JPG 2000-3.JPG

But I was so depress because the setup-program needs more than 714MB-disk-space . But I had only 430MB . I installed from drive d: . So disk d couldn’t be deleted .

2000-4.JPG

After that , I tried to use another way . That is , installing the operating system on the PC and copy the files into notebook . But I failed at last because the USB adapter could not adapt the harddisk .

Finally , I gave up . When I re-installed Windows 98 again . I was surprised that the softwere did work .

ctl1.JPG ctl2.JPG

Today , I got up at 7 o’olock . But I was so tired that I want to sleep on the class . There are only ten student in today’s lesson because it is Saturday . But no pain , no gain . I think I will pass the IELTS test !
