TOPIC: ISSUE28

TOPIC: ISSUE28 - "Students should memorize facts only after they have studied the ideas, trends, and concepts that help explain those facts. Students who have learned only facts have learned very little."

WORDS: 426 TIME: 02:34:29 DATE: 2008/6/27 19:07:49

Nowadays we are living in a special society, which is a Sargasso Sea of knowledge one. Living in such a society, newly developed information come from nearly every aspect, thus students cannot acquire the facts and its ideas, trends or concepts of every subject. They need to separate which facts should be dug in with those concepts, trends and ideas and which need not.

Acquiring facts related ideas, trends and concepts, which is the information to explain the facts, before students memorize facts, is an excellent method of study. According to a psychologist’s experiment, the human's brain is a memory that can easily learn those events which is related to the events that the brain has acquired before. That is to say, we can memorize new knowledge effectively if we can find out some other related events in our memory and try to learn both the knowledge and the related events together.

Simply but, if we do not search the related information in our memory while learning a new knowledge, the learning progress will become harder. For example, we can memorize a arithmetic progression quickly due to a formula in our memory that can work out all the numbers that belong to the sequence, however, if we do not know about the formula, we can only memorize the numbers one by one and may never acquire the whole sequence.

On the other hand, it is not all the facts that worth us to acquire the information to explain them. Our profession and occupation determined that in some fields, it is better to memorize facts than to acquire both related information and facts. Cell phones are being widely used now, but only a few professional persons can explain what GSM network is and how the cell phone works. The users of cell phones just need to know that a cell phone can be used to dial, to connect the wireless network and they do not need to figure out how cell phone invented or other details. That means knowledge of just the facts, cell phones, is enough for the users.

Therefore, it is necessary to acquire the related information of the facts when you are in your study field or major course, as you have acquired those information it will help you to memorize the facts smoothly. On the contrary, we cannot dig out all the concepts, ideas and trends that behind the facts in this era of information, which need us to aware that, for the facts out of our field, learn only facts is enough.

修复Windows、Linux双系统中因为重装Windows而丢失的GRUB

1、放入Linux盘。随便什么盘,LiveCD、安装盘都可以。设置用Linux光盘引导。

2、进入Linux Rescue模式,出现sh#

3、输入sh#fdisk -l进入磁盘列表。记下来自己Linux和Windows都安装在哪。

4、输入sh#grub,进入Grub配置界面输入

grub>root (hdX,Y)这里的X和Y代表是数字。即hd0,1代表第一块硬盘的第一个分区。根据你刚刚在fdisk里看到的内容填写。

如果正确,它会提示认出这个磁盘格式为Linux

grub>setup (hdX)此处的X和上一个数值保持一致,成功的话,会提示succeed

然后

grub>quit

sh#reboot

修复完成。

Fedora 8下成功安装ATI移动显卡驱动



(本文同步刊发于新浪blog:http://blog.sina.com.cn/ss1271)









最先前电脑的Win XP
SP2驾崩了,由于忙于期末考试,所以没顾得上重做系统。此番重做系统,一方面是眼馋同学的Ubuntu
8.04 LTS Destop,还有fedora 9,而我的ubuntu
8.04光盘还在荷兰到中国的路上,自己的fedora
9刻坏了,同学的fedora9貌似也有问题,反正不能引导,试过的U盘引导也失败了……


于是心一横,咱重新分区重新做系统~



手头只有Fedora 7的盘,不怵,可以yum到fedora
8嘛……大不了到fedora8再yum到9。

fedora7很顺利装完了,接下来费了我一天,大约10个小时左右,安装或者更新了1000+个包,总算Yum到了fedora8。不急着到9呢,先把我笔记本上安装多年linux未解决的显卡驱动问题解决了先。




具体步骤如下,首先确认你的fedora内核版本为最新。我用的是fedora
8应该目前不会有更新的fedora 8的内核了。

CODE:

# rpm -Uhv
http://rpm.livna.org/livna-release-8.rpm

# rpm --import http://rpm.livna.org/RPM-LIVNA-GPG-KEY

# yum install xorg-x11-drv-fglrx kmod-fglrx glx-utils



这期间可能要很长时间,也可能很短,比如我的长宽<10分钟搞定。这要视你的网速而定。所有过程都是自动完成的。你能做的就是等。








CODE:

# glxinfo | grep direct







查看是否安装成功。如果显示yes
的话就说明成功了。

----------------

如果是amd64位的cpu就接下去

实际上我们安装驱动的过程中就自动升级了内核。


修改/etc/grub.conf 在老的内核后面加上iommu=off






QUOTE:






kernel /vmlinuz-2.6…… ro
root=LABEL=/ rhgb quiet iommu=off





----------------

重起。

改分辨率。开启3D。



如果显示NO(我的就是NO)



那么尝试如下:

先到http://ati.amd.com/support/driver.html下载相应的驱动,比如我的笔记本显卡是:ATI
Mobility Radeon x1400
series,下载到本地是这样一个东西:ati-driver-installer-8-6-x86.x86_64.run,然后su到root权
限,输入:#sh
ati-driver-installer-8-6-x86.x86_64.run
,这样会弹出图形界面,你就一路下一步,比如最开始点continue,然后弹出一个协议,选accept,然后问你是automatic还是custom,默认是automatic,你就直接continue.最后装完,选exit即可。




然后,注销或重启,再次运行终端,su
到root权限,输入#aticonfig --initial(特别注意,这里initial前是两个横--),会出现以下类似的提示:




[root@localhost ~]# aticonfig
--initial

Found fglrx primary device section

Using /etc/X11/xorg.conf

Saved back-up to /etc/X11/xorg.conf.fglrx-1


注销,您的ati显卡驱动装好了!但您会在系统/管理/显示的硬件信息中看到:显卡信息:Unknown
video
card,不过没关系,只要点“配置”中,有“fglrx-Vendor-supplied
driver for fglrx cards"
这个信息就行了。





目前我的是装好了,估计是驱动的伟大问题,导致我开启3D白屏……


不过分辨率是正常了。开不开3D无所谓了,因为那个对我来说不常用到。

在Linux下配置PPPoE联网-----适用于ADSL和长城宽带等

要在Linux下使用PPPOE认证方式,必须安装PPPOE客户端软件。下面说明如何进行安装:

本文以RedHat Linux 6.2为实验平台,其它平台的Linux安装办法可以参照下面从源代码进行安装的步骤。

一、安装的前提条件

1.确保安装了网卡并工作正常

使用命令

#ifconfig eth0

查看网卡状态

2.在系统中不要设置默认路由(网关),让ADSL拨号后自动获得

如果已经设置了默认路由,使用以下方法删除:
在文件 /etc/sysconfig/network 中删除 GATEWAY= 这一行,然后以root执行:

#/etc/rc.d/init.d/network restart

3.已经安装了pppd软件包

如果存在文件 /usr/sbin/pppd,则说明已经安装了pppd;
如果未安装,从RedHatLinux 6.2安装光盘上安装ppp-2.3.11-4.i386.rpm这个软件包

二、安装PPPOE客户端软件

Linux下的PPPOE客户端软件比较多,而且大多使用GNU License,我们推荐使用rp-pppoe这个软件包。从http://www.roaringpenguin.com/pppoe/这个网站上,不仅可以下载 RedHat 62平台下的rp-pppoe的二进制软件包,而且可以下载源代码软件包。

1.二进制软件包的安装:
A.下载二进制软件包
http://www.roaringpenguin.com/pppoe/rp-pppoe-3.2-1.i386.rpm

B.进行安装

以root执行:
#rpm -Uvh rp-pppoe-3.2-1.i386.rpm

2.从源代码进行安装:

从源代码进行安装同样适用于其它平台的Linux,但必须在Linux系统中安装gcc编译器。

A.下载源代码软件包
http://www.roaringpenguin.com/pppoe/rp-pppoe-3.2.tar.gz

B.解压缩

#tar xvfz rp-pppoe-3.2.tar.gz
#cd rp-pppoe-3.2
C.进行编译和安装

运行脚本
#./go
将自动进行编译和安装,最后,调用/usr/sbin/adsl-setup进行配置,具体解释见三。

三、配置PPPOE客户端软件

安装完软件包后,必须配置pppoe的配置文件/etc/ppp/pppoe.conf,从而让ADSL拨号时使用配置文件中的用户名、密码等参数。我们不必手工改动这个文件,可以使用adsl-setup这个工具进行配置:

#/usr/sbin/adsl-setup

当出现
>>> Enter your PPPoE user name :
输入ADSL帐号的用户名

当出现
>>> Enter the Ethernet interface connected to the ADSL modem
For Solaris, this is likely to be something like /dev/hme0.
For Linux, it will be ethn, where 'n' is a number.
(default eth0):
输入 eth0 ,这是ADSL相连的网卡的名字

当出现
>>> Enter the demand value (default no):
输入 no

当出现
>>> Enter the DNS information here:
输入 server ,这表示使用ADSL拨号自动获得的DNS服务器IP地址

当出现
>>> Please enter your PPPoE password:
输入ADSL帐号的密码

当出现
>>> Choose a type of firewall (0-2):
输入 0 ,不使用防火墙

当出现
>>> Accept these settings and adjust configuration files (y/n)?
如果输入的信息正确,输入 y ,完成配置,否则,输入 n 重新输入。

四、启动PPPOE客户端软件

使用命令

/usr/sbin/adsl-start 启动PPPOE客户端软件,进行连接,如果成功,将出现
Connected;
如果不成功,请检查网线、ADSL MODEM等物理设备,并查看 /var/log/messages中的信息
/usr/sbin/adsl-stop 关闭和ISP的连接
/usr/sbin/adsl-status 查看当前连接的状态

如果想在Linux系统启动时自动启动ADSL连接,输入以下命令
#chkconfig --add adsl
将在当前的运行级下加入ADSL的自启动脚本

五、测试

当连接成功后,使用命令
#ifconfig -a

在输出中应该含有关于 ppp0 的一堆信息,其中还绑定了 IP 地址,说明已经从拨号中获得了IP地址。

使用命令

#netstat -nr

查看路由表信息,这时的默认路由应该是上面获得的IP地址。
如果没有默认路由,我们可以手动增加:

#route add default gw 上面获得的IP地址

使用命令

#nslookup www.sina.com.cn

如果解析出新浪的IP,说明已经从拨号中正确获得了DNS服务器

最后,使用命令ping某个域名或IP,如果有响应,表示你已经大功告成了。

六、其它说明

RedHat Linux 7.1已经集成了rp-pppoe这个软件包,只不过版本有些低,如果你不在意版本高低,可以直接进行三后面的步骤。
