Linux CD burning under the
linux CD burning under very simple, just enter the following command in a terminal window, you can:
cdrecord-v speed = 2 dev = 0,0,0 cd.iso
cdrecord software release generally, if it is not installed when you install the system in your installation disks should be able to find where to install it .
speed is an indication of the speed of recording options, can be set according to actual situation, but no more than CD-R and the maximum speed limit burner; dev is the recording equipment, options, may be
cdrecord-scanbus
command to obtain, cd.iso is to burn the image file, you can join the path of the actual situation.
how like? Simple, right?
Now, there are several issues worthy of note:
1 image file how to do
linux there is a mkisofs command is very powerful, can do data CD-ROM, CD-ROM and other systems, but also can be done bootable CD-ROM.
mkisofs-r-o cd.iso-m temp burn /
is the basic use,-o cd.iso specify the CD-ROM image file name,-m temp to exclude temp directory or file, burn / will be The directory files added to the image, the more advanced use please refer to the documentation, or man.
2 CD-ROM copies of
like MS system under the dual disc burning on the disc is not tried, but made the image file and then burn more secure, even been to make this method, then do not need to re-use mkisofs command, and there are even more simple way, so that CD-ROM is not a trace of information leakage, including start-up information:
dd if = / dev / cdrom of = cd.iso
/ dev / cdrom device name for the CD-ROM , usually / dev / cdrom, can be given according to the actual situation; cd.iso it would not have to speak.
3 burner installation
linux system only recognized SCSI burner, now mostly used the IDE interface, needs to do a conversion, hardware, link, run the command cdrecord-scanbus, if not following a similar message of the equipment has not been systematically identified:
Cdrecord 1.11a15 (i586-mandrake-linux-gnu) Copyright (C) 1995-2001 J salamander g Schilling
Linux sg driver version: 3.1.22
Using libscg version 'schily-0.5'

0,7,0 7) *
The solution is in the / etc / lilo.conf file to add append = “hdb = ide -scsi “, hdb is the first IDE interface from the mouth, if your burner in the second IDE interface, should be changed to hdc (master) or a hdd (from), Save and then run lilo command, and then restart the system, then test, If that does not, in the / etc / modules.conf file by adding the following two lines to reboot the system
probeall scsi_hostadapter ide-scsi
probeall usb-interface usb-uhci ehci-hcd
If not, explain system kernel is not configured well, need to recompile the kernel.
Attached: dual lilo.conf (part)

append = “devfs = mount mem = 383M hdc = ide-scsi”
read-only
4 linux burning under the very powerful, you can also burn VCD, CD and so on, can refer to the HOWTO and other documentation. For some graphical front-end software, even never use the command line is very simple why the mouse Gaode little less complicated? Of course, if you prefer you use, distribution generally take years.
5 on the MD5SUM
download the CD-ROM are generally mirror with MD5SUM checksum, which is used to detect whether or not the file the correct checksum in linux is very convenient to use them, as long as the terminal window Enter md5sum cd.iso, while you can calculate the mirror file MD5SUM, as long as he was compared with the site can be provided, if different, the documentation may be wrong, but it does not rule out the wrong website checksum the possibility of experiencing such a situation, in order to avoid re-download, it can be tested: If it is the system CD-ROM, the first test whether the use of vmware to start, if not start, it is best to re-download, if they can start, followed by detection of the various packages correctness, linux CD-ROM for each document within the basically provide a md5sum, file names are generally MD5SUMS, mirror file is loaded into the RPMS directory, run the md5sum *. rpm will be listed for each package md5sum then with a completely different one by one within the MD5SUMS file comparison (using the diff can increase the efficiency), if no errors, you can rest assured that boldly discs, if the package is not important is incorrect, you can also discs, when you do not choose to install the software bag no problem.

1. How can more easily edit multiple files at the same time, for example, to switch between multiple files,
Copy Paste content.
2. I want to edit the text to find a word, almost taught in the book are the use of “/ word”,
However, if the word is on the cursor, I have to a character a character Enter the word,
do is not very depressed? For example: / i_want_to_search_this_long_word.
3. My job is mainly C / C + + programming, really want to like VC, as in the left to see a list of files
the project, and the Class, Function, Struct list and have opted for
will be able to jump to the appropriate location.
4. is and programming related, in the VC inside, Build the Browse Info after, F12 on
can be very convenient in the class, variable, constant, etc. definition,
implementation or reference inter – jump, which is very convenient very useful.
5. In the VC inside, in a .C / .cpp file, for include files, for example,
# i nclude “foo.h”, you foo Office, + + g can jump
the header files go, is really easy ah. Is vim is not available?
6. If in Vi in the same view as the Explorer file list, and can choose just fine.
There are more problems, I do not have to list one by one, because my article was not to become a
Wikipedia book, but rather to those who used the vi later dropped (:-), Of course not switching to the Emacs kind),
and novice Linux / vi, but the Vi read books but I felt very nice people to read.
OK, the above six problems solution.
1. vim.sourceforge.net download ranked No. 3 of the bufexplorer.vim
2. vim.sf.net in the Tips of the No. 1 of the “Super Star”, Oh, when the cursor is in this
word on when, according * to be able to, and in Editplus, press Ctrl + F3 as easy.
Another tip is to start looking for write / post, you can put the word under the cursor
copied to the command buffer Department, a very useful Tip.
3. a) want to see Class, Struct and other lists, you need No. 1 of the taglist.vim,
With it, Vim is now looking much more pleasure to the eye. b) want to have the project file list: You need to
No.7 of Project.vim, there are the two, VC basically simulate the left side of the window out.
4. There taglist.vim help feel that you have a lot of convenience, taglist need ctags
can be achieved, ctags's role is to Symbol build C code tags, What are tags?
you have passed the Vim's Help (: help) to understand, Ting Xiang hyperlink. However ctags functionality
is not strong enough, because this work cscope do better than it did, but also stronger.
If you are interested in the use of cscope, then you should take a look at cscope.sf.net, while there are a lot of Vim version
no built-in support for cscope. You can use the Vim using: version view. If not,
to congratulate you, you have the opportunity to own Qin Shouba Vim compiled once. Oh, note that. / Configure
when the – enable-cscope. With cscope, see item code with Vim do even more powerful!
5. gf – It's that simple, Hehe. If you still can not find the header files, how can I do?
Please: help path. correctly set the path where the header files is very important.
6. Try: Ex and: Sex: e. and: e / usr / src, you will all understand.
Other
7. must go vim.sf.net on the Top10 of the script are placed in their own Vim try,
must take the No.2's Tip preserved view at any time. gvim = vim-g
PS
went to the bar here, writing this article because I spent a whole day of time to learn Vim,
and installation and testing the use of these Scripts, finally find Comparing the use of entry-level and smoothly by Vim.
In fact, access to and use of Vi is also a very long time, but never been to vim.sf.net, So
always felt that Vi is very easy to use, and now change in attitude, I hope this article will help
those who want to learn Vim's friends entry.
If you are learning Emacs, then you must go www.emacswiki.org look at the Tip,
download one of the script. But I think Vim has been good enough. Vi because I like the way
to move the cursor with j, rather than Emacs like Ctrl + n, need two hands, He He.

This paper describes a variety of games under LINUX, including LINUX comes with a small games, classic game simulator, support LINUX and other large-scale games, such as DOOM3, as well as run the WINDOWS way to introduce popular games. Game fans come with me! In this paper, REDHAT9 example
(This article published in the linux Union Station
http://www.xxlinux.com
Welcome to paste, but please keep the above information, there are problems to the site to the Forum)

1, LINUX next game that comes with playing cards
like a friend can play “patience” This poker game, if you install the fashion of the game, then on the game menu, which integrates 10 of several poker games are played, such as the neutral gear Solitaire, 48, Hearts, etc. There are also many traditional games are played strange games are played, we recommend everyone try, there is always a right for you ~ ~
mine but we are not familiar with it? In the LINUX Lane called Kmines, go look the same. There are many WIN a classic situation of having no games in my house, a single machine host a red 4.1, inside there were 33 titles as well: potatoes guy, KWIN4, Kbattleship are too many to see their own bar
2, FLASH games
As long as your browser, installed the FLASH plug-in, then had to play in the IE online FLASH game where you can still play, such as The King of Fighters 2000, Street Fighter, MM favorite games and so on, nagging one: I heard that swept the 1:00 a FIREFOX browser, recently discovered a fatal mistake, hope we do not forget patches (May 2005), the following excerpt of the game is my web site, we can come here and
http://gamezone.qq.com
3, simulator games” br /> 1, “Three Kingdoms”, “Tomahawk” and other Nintendo games that we can install the simulator in the WINDOWS game, also in LINUX can be, we only need to install Fce Ultra, which provides the code for the LINUX platform installation package:
http:// www.huihoo.com/game/linux/simulator/fceu096src.tar.gz
, compile install the emulator is a fairly simple thing: download fceu096src.tar.gz, Expand into a temporary directory, enter the directory will Makefile.unixsdl copying Makefile, then run make, if all goes well, will be generated in the directory fceu enforcement procedures. In the command line, type “$. / Fceu” will be command-line help, try the “$. / Fceu-fs contra.zip”, see you a long absence, “Contra” screen it? “-fs” option will allow fceu run in full-screen mode.

There are a number of different platforms simulator download addresses, please look at the demand to install:
2, family of five generations of simulators: Dgen / sdl
Download: http: / / www.pknet.com/ ~ joe / dgen-sdl-1.23.tar.gz
to install: # tar-jxvf dgen-sdl-1.23.tar.gz
; # cd dgen-sdl-1.23
#. / configure
# make

3, Super Nintendo emulator Snes9x
Download:
http : / / www.lysator.liu.se/snes9x/1.42/snes9x-1.42-linux-x86.tar.gz
to install: # tar zxvf snes9x-1.42-linux-x86 . tar.gz
4, PS emulator ePSXe
Download:
http://www.epsxe.com/files/epsxe160lin.zip
to install: # zip-d epsxe160lin.zip (extracted can be used directly)
5, arcade emulator, XMAME
Download:
http://yarrow.freshrpms.net/rpm.html?id=1342
Installation:
required to install all the packages to download in the same directory, then run:
# rpm-ivh *. rpm

4, large-scale 3D game
more small game you are not enjoyable , then I play with these large-scale 3D games, these games are the LINUX version up and running without any problems, such as: QUAKE 3, UT2004, DOOM 3 and other large 3D games

1, QUAKE 3
Download:
ftp://ftp.idsoftware.com/idstuff/
47M size.
installation: # chmod u + x linuxq3ademo-1_11-6_x86_gz.sh / / add the implementation of the permission
# ./linuxq3ademo-1_11-6_x86_gz.sh
installation process will prompt some of the problems, choose Y / N answer can be, and so simple to you in English I do not reprinted, mainly because you are prompted to install, whether to accept the license agreement, is to create a shortcut, is in need of help files.
As for how to play, I have more food anyway.

2, DOOM 1,2,3
before downloading take a look at your configuration, DOOM3 such a big game requires that your machine P4 1.5, RAM 384MB, at least 2.2G of hard disk space, 64M or more of video memory (remember that in order to have a super-rotten “Jiang Hu” and to upgrade the computer's scenario)
Download:
ftp://ftp.idsoftware.com/idstuff/
(download an excessive number of, as far as possible in a number of off-peak hours to download)
installation and QUAKE3 similar, then no, the information on to my stand to see LINUX installed software solution''_''

3, Unreal Tournament 2004 (UT2004)
Download:
http://www.unrealtournament.com/ut2004/downloads.php
Choose LINUX download the DEMO version, size 275MB
to install the same as

5, I'll play CS, Diablo, Star and other games, where you can go to download an emulator to run programs to see if, like Cedega,, they are the WINDOWS software simulation running on LINUX, many games It can be below the smooth operation, as to download and install, please yourself, and then the words would not come to my small station on the bar:

which I think the most interesting aspects

thread, there are two:
1) can be cut into the thread
2) isolated threads and processes
thread Comparison:
difference: to create a new process is the parent process, where a section of code, function, or had the procedure; created thread is a function.
similarities: the process has its own attributes and resources, the thread, too.
/ * A `sigset_t 'has a bit for each signal. * /
# define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int)))
typedef struct
(
unsigned long int __val [_SIGSET_NWORDS];
) __sigset_t;
with a bit that a signal of up to 1024 signals. With the bits that can save space, but the setting is not easy, so there is a set of functions can be easily set these bits:
sigemptyset (Full set 0?)
Sigfillset (Full set 1?)
sigaddset
sigdelset
sigismember
——————–
to set up and modify the program signals receive :
that determine our procedures for dealing with the signal system, or occlusion (ignore), NOTE: It is blocking, rather than ignored. The two are different concepts.
the first thing to know:
a program by default has been set of 15 signals (process, resources, automatically generate a sigset_t type of space), and capture them to work with the default function, there is the default action. SIGSTOP (19), SIGKILL (9) These two signals can not be modified to capture or ignored.
the above five functions that we have set up just for sigset_t, the process does not modify the resources of the sigset_t space. We want to use:
sigprocmark (int how, const sigset_t * set, sigset_t * oldset)
be set.
this function is to understand that the difficulty:
sigset_t * set our own definition of the space program.
sigset_t * oldset resources for the process space. in order to get the last set the conditions exist.
you want to compare the two to get to deal with signals.
Function Description
sigprocmask () can be used to change the current signal mask, its operation in accordance with parameters of how to determine the
SIG_BLOCK new signal mask from the current signal mask and parameters set specified the signal mask for union, I understand that oldset and set the signal set are set (+)
SIG_UNBLOCK the current signal mask removed parameter set the signal mask specified (-)
SIG_SETMASK the current signal mask is set to set the specified parameters of the signal mask (=)
If oldset argument is not a NULL pointer, then the current signal mask will return this pointer. get old data, sigaction also have this capability.
return value
Success returns 0, -1 if an error is returned.
error code
EFAULT parameters set, oldset pointer address is not accessible.
EINTR The call was interrupted
——————-
to set up and modify the program signals Action :
int sigaction ((int signum, const struct sigaction * act, struct sigaction * oldact);
hard to understand where also lies in struct sigaction * oldact. This is in order to obtain the last signum of the right to set conditions exist.
