Flash Player 9 and Linux

YES, now I will be able to play to the games written in Flash and to enjoy the new web sites based on Flex2.0. This time, it is as easy as pie to install : just download the plugin from this adress:
http://www.adobe.com/go/fp9_update_b2_installer_linuxplugin
uncompress it and copy libflashplayer.so in your user's directory of plugins of Mozilla: it must be something as: ~/.mozilla/plugins/ ... Restart it, and now you are ready for web site based on flash (you can test the MacDo's game). And now enjoy the beauty of flash...

Close and manage file with vim

Let's continue with the best practice of the vim software:

:q
to close vim
:q!
to close vim without recording the modifications
:w
to write the modification
:w [NEW_FILE]
to write the file you are editing in NEW_FILE
:w! [FILE]
it is the same action as before but you force the action
:n,mw [FILE]
save the lines from n to m in the file FILE
:n,mw >>[FILE]
add the lines from n to m at the end of the file FILE
:wq ou :x ou ZZ
Save the file and close vim
:e!
edit the file again but with the version on the disk
:e [FILE]
edit the file FILE rather than the current file (:e! to force the action)
:r [FILE]
insert the file FILE after the current line
:rn [FILE] ou :nr [FILE]
insert the file FILE after the line n
n is either a number, or . for the current line, or $ for the last line.
:version
display information about vim

it should be enough today to play a little and increase your productivity lol ;-)

Kapersky and the 20 viruses

Kaspersky has just published its list of the top 20 malwaress (Virus/Trojan/Worm/...) spreaded by mail. As a consequence, in the case you see those little creature: don't click on them, don't try to play with them...

1. Email-Worm.Win32.NetSky.q
2. Email-Worm.Win32.Warezov.dn
3. Email-Worm.Win32.Bagle.gen
4. Email-Worm.Win32.Scano.gen
5. Email-Worm.Win32.Warezov.ev
6. Email-Worm.Win32.Bagle.mail
7. Email-Worm.Win32.Warezov.dc
8. Email-Worm.Win32.Mydoom.l
9. Email-Worm.Win32.Mydoom.m
10. Email-Worm.Win32.Scano.e
11. Email-Worm.Win32.Warezov.do
12. Email-Worm.Win32.NetSky.aa
13. Email-Worm.Win32.NetSky.b
14. Net-Worm.Win32.Mytob.c
15. Trojan-Spy.HTML.Bankfraud.od
16. Email-Worm.Win32.Warezov.eu
17. Email-Worm.Win32.Warezov.gen
18. Email-Worm.Win32.Bagle.dx
19. Email-Worm.Win32.Warezov.dh
20. Email-Worm.Win32.Scano.aq
    

Some new players in the team: Warezov.dn, Warezov.ev, Warezov.dc, Warezov.do, Warezov.eu, Warezov.gen, Warezov.dh.
Some malwares which begin to extinguish: NetSky.b, Mytob.c, Bankfraud.od, Scano.aq. Unfortunately we can notice the return of: NetSky.q, Bagle.gen, Bagle.mail, Mydoom.l, Mydoom.m, Scano.e, NetSky.aa, Bagle.dx, this means that some people don't have an uptodate antivirus, as a consequence they are infected and spread the threat! So install an antivirus if you haven't one already and ensure that it is uptodate (not only Kapersky, but Norton too, or ClamWin...)

LastFMproxy, Streamripper and Amarok

I have recently discovered Lastfm, the community radio. It is a great thing just give it the name of some artists you like and it will gather musics of this artists or similar artists... After that you can be a little more specific and say if you like the music or if you want to ban it! Most of the time the choices are excellent and they are becoming more and more relevant with the time and your selection. If you want to read the lastfm flux in one of your old player on linux, you should try lastfmproxy (you can find it here ), just uncompress the archive with this command:
tar -xvzf lastfmproxy-1.1.tar.gz
then go inside the directory you have just created, modify the config.py file with your username and password for Last.fm. That's it, now you can run the main script:
python main.py
you should see something like:
Starting LastFMProxy 1.1...
Connecting to last.fm server...
To tune in, point your browser to:
http://localhost:1881/
The last line stand to give you the url you can listen in your old player... So start it and open this url. That's working ;-) Great.
In all the previous part I said "old player", it is because with the great player of linux: Amarok, you can directly play Last.fm: you need to go in Settings and that's it! You can now choose open a Last.fm flux! Enjoy.
You probably wonder why I told you about LastFmproxy if you don't need it to play LastFM if you use Amarok... It is because there is a little trick: if you listen LastFM, you only listen it, when you shut down your computer, or when the music is finished, there is no way to listen it again! So let install streamripper to record all this music on your computer. First of all you should only record music with a copy left, otherwise you are out of law! Now start lastfmproxy as explained before. And type this little command:
streamripper http://localhost:1881/lastfm.mp3 -d /home/mynqme/mydirectory -r
you can notice 3 arguments:
the radio you want to listen and record
the directory in which you will save music
the last argument will let you listen the music you are recording.
Launch the command, go to Amarok and open the url http://localhost:8000
That's it you can listen and record music on LastFM

How to verify the root user id on SUN?

If you program sometimes on Sun Solaris, you have probably noticed that the syntax is not always the same as the one of Linux, or HP-Unix... This time, before running my script I had to verify that it is root, who runs the script: after 30 minutes of headhache, I finally find a way: enjoy the aspirin

WHO=`id | cut -f1 -d" "`
if [ ! "$WHO" = "uid=0(root)" ]
then
echo "You must be super-user to run this script."
exit 1
fi

How to get rid of output of your scripts?

Just add at the end of your command line: >/dev/null 2>&1 so you redirect fd1 to /dev/null, then dump it onto fd2:

Normally: fd1 -> stdout fd2 -> stderr

>/dev/null: fd1 -> /dev/null fd2 -> stdout

2>&1: fd1 -> /dev/null fd2 -> /dev/null


Now no more output, it is very interessant espscially for cronjob.

Google Calendar && Kontact

I only start to fill my Calendar by Google, but I have also my calendar on my portable with Kontact... The question which often arises in these cases, how to share information between the two (except if you are schizophrenic...) how to synchronize the two calendars??? Mr. Google once again thought to everything: it is simple: settings > calendars > share this calendar > calendar details.... There you will see small squares of color XML, iCal, HTML on the line private addresse. Select iCal and copy the address which is kindly given to you by Google. Now on Kontact: File > Import > Import Calendar... At this time there, instead of seeking on your computer a file, enter the address given by M.Google answer two or three questions... that is it. You finally could be more effective in your work, to optimize your life; -)

Linux:: AmaroK

In the inuits legends, Amarok is the giant wolf which devours the imprudent hunters, who hunt alone the night. In the world of computers, Amarok is the application which could too devour the imprudent users of Windows which use the old old old Itunes... Amarok is an application of the free world which works exclusively under Linux or Unix.

AmaroK allows inter alia:

• to manage advanced playlists
• to develop new functionalities via scripts
• to record statistical data of a song even if this one is renamed or moved
  
• to use K3B (burning software for Kde) for the CD engraving
• to use the data bases to store information of music
• to use your iPod
• to manually configure a generic reader with key format USB
• to benefit from the crossfading
• to use MusicBrainz to recover informations on your music
• to recover the words of the songs
• to recover the covers of albums on the Amazon site
• to recover on Wikipédia the articles on the album, the artist or the song in the course of listening
• to manage the support of radio operator flows of last.fm
  

Unfortunately for the users of Windows, Amarok will never be carried under Windows because of:

• its licence LPG
• KDE-libs (which it uses)
• need somebody to do it...

Linux:: How to make a substitution in VIM?

Just type:
and then
:%s/old_chain/new_chain/g
To highlight a string, just move the cursor to the strinf, then press and then # to move from one occurrence to another, just press n.

Linux:: Use of ssh-agent

You often connect remotely by using ssh… and you are fed up of always having to enter your password: ssh-agent is made for you. ssh-agent is a daemon whose only goal is to keep in memory (in a protected way) the “passphrase” so that it is not necessary to type it with each use of ssh.

The following order creates the variable SSH_AUTH_SOCK which contains the way of a socket that ssh, SCP (and other orders) will use to dialogue with ssh-agent:
$ ssh-agent

To communicate the private key and the sentence of master key to ssh-agent by means of ssh-add:
$ ssh-add ~/.ssh/id_rsa
Enter the passphrase for /home/user/.ssh/id_rsa:

The private key is thus deciphered and stored in the mask of ssh-agent, lends to being used
One can now use ssh and SCP without having to enter the password.

Linux:: How to install IMVU on Linux

Sorry, I do not have a magic receipt, I tested Wine and Crossover well, but I had some problems with glu32.dll and opengl32.dll… I have thus to try the vitualisation and my Windows machine in Qemu. It is great, it works! I launch only that, and I have to remove the updates automatic of Windows, But yes, I can regenerate my virtual machine, therefore in the worst case the virus or the Trojan will remain there only one hour or two: -) not of chance for hackers. Moreover I am seeking how to accelerate my virtual machine: there that could become really a magic receipt, moreover if you have some already: as usual leave me a message

Linux:: How to compare two list and find common element with Perl?

This trick can only be used if you are sure that there is no double value in a same list. You will understand why. First create an hash table (%seen), the basic idea is for each element ($_) of the merge of the two list, we will store it in the hash table. The first time the value is store; seen value is equal to 0, so the grep filter prevents this value to be record in @common. The second and other time an element will be seen, because it will be store with the same key value, the $seen{$_ } will be not null and so the element pass the test of the filter and is recorded.


my %seen;
my @common = grep {$seen{$_}++} @list_1 , @list_2;


but for doing that you need that list are unique (not two times the same element in the same list.) For doing that you can use this function:


sub Array_Uniq
{
my @List = @_;
my %FutureList;
foreach(@List)
{
$FutureList{$_} = 1; # delete double values
}
return (keys(%FutureList));
}


Linux:: XEN

It makes a long time that I didn't speak about virtualisation… However it is a subject which will be discussed more and more . Moreover the RedHat company has just announced the nearest installation of technology XEN within its version for professional. Contrary to other technologies of virtualisation such VMWare or Qemu which simulates the material and the bios, the virtual machines under XEN has access to the material thanks to XEN modified kernel. The result of this other paradigm is a virtual machine almost as fast as the machine host. So enjoy the virtualization!!! The only constraint is that the architecture of the virtual machines must enable them to use the technology XEN… contrary to VMWare and Qemu which does not require modification of “guest” OS. It is not a problem with opensource OS such Linux, whose code was already modified to be able to turn with XEN, on the other hand what is at stake is Windows… And it is there that the real difficulty arises: much user of Linux uses a virtual machine to make turn Windows, even if the team of XEN said to have modified Windows to allow to make it turn under XEN, some licences prevent the team from publishing… Let us hope that the agreement between Microsoft and XEN could change the situation. In addition the arrival of dual the core and technologies of virtualisation directly within the processors should end licence's problems mentioned herebefore and another side to still improve quality of virtualisation… The bootloader could thus belong very soon to last and the stories of I am under such OS, I must reboot… will be finished soon.

Linux:: DVB-T Freecom TV on your PC

I have just bought a DVB-T usb key Freecom. I thus took one having best price quality: Freecom DVB-T

I bought it on the Amazon web site for some 45$ It works well under Windows: even if the installation program is quite bad… that still finish to work. The good point is that the antenna comes with a MediaCenter software: very interesting when as me you have only one Windows XP pro without the media center. But you suspect well that I have to install it under Linux; -) Guess? YES! It works better: no problem the image never freeze : a pleasure and all that with only the small provided antenna! To install the DVB-T key, do not try modify your kernel and to add modules to it; best is to use tools from linuxtv:

1. Download the firmware: dvb-usb-wt220u-fc03.fw
2. cp dvb-usb-wt220u-fc03.fw /usr/lib/hotplug/firmware/
3. apt-get mercurial build-essential (et les header de votre kernel si vous avez un kernel standard)
4. mkdir /usr/src/modules
5. cd /usr/src/modules
6. hg clone http://linuxtv.org/hg/v4l-dvb
7. cd v4l-dvb
8. make-config

Now you only need to reboot your pc and there is a small orange light… You do it: congratulation! Now go in Kaffeine: play a little with the configuration menu and now you should be able to watch TV programs on your computer: cool isn't it. Of course before that I had some problem but if you have problem write a post and I will try to help you

Blender and "Elephants Dream"

You probably know Google Video: this is an excellent animation film you can find on Google Video: Elephants Dreams

What is at stake with this small cartoon is that it was entirely created with free software: like Blender… Thus if you feel the heart of Tim Burton, enjoy Blender.

Regarding Elephants Dream, my opinion is that all the machine is in the head of the young person and that the old man is there to only try to maintain this beautiful machine. In fact he know that it can be realized only by maintaining the young person in the belief of the machine… If you have divergent opinions: leave a post; -)

[Some Thinks about everything] Linux:: Qemu and the mouse

I had problems where the mouse would stick at the bottom right-hand corner, becoming unusable. A solution to this is before you run qemu, type in your terminal this command:

export SDL_VIDEO_X11_DGAMOUSE=0

Now you can play with your virtual machines

If you want only to displays the first and third columns, it seems impossible... Actually, only for a windows user, because Linux or Unix
have a powerful tool to manipulate those file. One year ago, my girl friend had a huge huge file, a bit like that for
a study about obesity, she tried to opened it with excel... But excel freezed becquse the file was too big... So she asked me
for a solution: I did all she wanted only by using command line tools and espescially awk! So now some example to measure the
power of awk. The awk command is as you have already probably understood a power pattern matching language that allows you to modify input lines by manipulating the fields they contain.



$ awk '{print}' file.txt

This has the same result as $ cat file.txt, it displays all the content of the file


$ awk '\toto\' file.txt

This has the same result as $ grep Heathrow file.txt, it displays only line which content the word Heathrow.


$ awk '\Lieberman\ {print $5,$7,$12}' file.txt

It only displays columns 5, 7 and 12 of line containing "Lieberman"


$ awk '{if ($3 <>

It displays columns 3 and 7 if the key 3 is less than 2000.


$ awk -F":" '{ print $3 "\t" $1 }' /etc/passwd |sort -g

Display user by increasing userid. Notice that if you want to print a tabulation you've to use \t, idem if you want print a new line, use \n.


$ awk -F"\t" '{ print $4 "\t" $10 }' file.txt

You can specified the separator with the command -F"\t" (notice that tabulation and space are the default one)

And this is only the beginning with some file, where you use a end line to separate data and a some sign like @ to separate
a group of data,
you can use awk to retrieve some informations:

$ awk ' BEGIN { RS="^"; FS="\n" } /London/ ' file.txt

This kind of command permit you to process file like this one:

^London
Airport: Heathrow
Bus: First

^Paris
Airport: Charles de Gaulle
Bus: RATP

Incredible isn't it. Some other links to improve your "awk" skills:
