Meet Compton - compozite manager for Lubuntu with shadows, transparencies and smooth transitions Installing it on Ubuntu 12.04

In Lubuntu 12.10 You can have shadows, transparencies and smooth transitions in your windows and programs thanks to Compton, the new composite manager in town. It's a fork from xcompmgr-dana (which is a fork istelf from xcompmgr). Thanks to our pals at Crunchbang Linux, we can use the GIT versions on Lubuntu too.

Download your 32bit or 64bit version and try it while it's hot. Combine it with your favourite dock or whatever. And this program solves the problem that Lubuntu 12.10 users may have with other composite managers, like Cairo or XCompMgr. You can check the screenshot to see it's really beautiful, but I can sure you that it's really fast too!

To install it on Lubuntu 12.04 you need to get the libconfig9 from 12.10

Thank you,

following twitter users at once from ruby

You need to create a new twitter application on dev and create a callback url for it

you can start with the code from twitter-app https://github.com/jnunemaker/twitter-app

clone it with git  , and then run
bundle install to have all the requirements in your rvm

Then create a button for it or a text box where you insert one user that you want to follow
and for each follower for one user you can add it to your list of followers after you aprove the app






I have added twitter.local in hosts also in domains anyware
and the callback is

http://twitter.local:3000/sessions/callback

More documentation for follow is here

Enabling spamassassin in claws email

I was using sylpheed  so i have decided to enable local scanning for this i needed to upgrade the email client to claws mail (it does have the sa scanning plugin)

so first remove the sylpheed , then install claws email
sudo apt-get install claws-mail
then install the sa plugin

claws-mail-spamassassin


next step is to enable the spamd daemon

in /etc/default/spamassassin

enable
ENABLED=1


sudo /etc/init.d/spamassassin restart

Next load the plugin in the email client

and then configure it to use the local daemon

You can see it at work by marking sad figure over the emails with spam
I have created a filter to move them to Trash folder

Why amazon ec2 is better than heroku : it's the price

Compared with a ronin database instance = 200$

For 57.6$ per month if we calculate month=30 days on ec2 i can get a small ubuntu linux instance with 1.7G of ram with a lot more than 10.000 rows

http://aws.amazon.com/ec2/instance-types/

After that installing a firebird database can be easy if i choose a ubuntu instance

Next you can add nginx/django just for fun

For backup there are many python scripts to backup to s3/ebs snapshots

PHP GD Bundled - Compilation Instructions for Ubuntu 12.04

I needed to recompile the gd in ubuntu 12.04 to work with gd bundled version Warning i don't use mysql but only firebird so your requirements may vary

1. Open up a terminal.
2. Become root by typing su and enter your root password when prompted.
3. Download some packages we'll need for the install. Type apt-get install build-essential debhelper fakeroot dpkg-dev firebird2.5-dev 
4. Change your current directory to your source one. cd /usr/src.
5. Download the PHP 5 source code by typing apt-get source php5.
6. We also need the PHP 5 dependencies. To download these, enter apt-get build-dep php5.
7. Go into the downloaded PHP directory. cd php5-XXXX. just press after you've typed php5- to complete the folder name.
8. Now we need to edit a config file to change it into the bundled version of GD. Type  editor debian/rules. (I have removed any reference to mysql in the cofigure lines )
9. Locate the line that says --with-gd=shared,/usr --enable-gd-native-ttf \ and change it to --with-gd=shared --enable-gd-native-ttf \ by removing ,/usr. (Press ctrl+w to find something, if you search for gd, it is near the second occurrence). To save the file, we need to press ctrl+x then press y and then enter.
10. Now we've done setting up we now need to compile it. Type dpkg-buildpackage -rfakeroot -d
11. When it's done, you should have a load of .deb files in the parent directory. Find the one starting with php5-gd.
12. Install it by double clicking on it, or from the terminal, type dpkg -i php5-gdXXXXXXX just press after you've typed php5-gd to complete the file name.

Building Linux Kernel 3.X.X-RC-X with an php script on Debian / Ubuntu

Install the prerequisite packages

$ sudo apt-get install kernel-package php5-cli git-core fakeroot ncurses-dev
$ sudo su
# git clone git://github.com/mariuz/kernelcompile.git
# cd kernelcompile
# php rc-kernel-compile.php

if all is ok you will be asked for kernel build option (menuconfig) (they are copied from your system config) after you have chosen the menu you can press exit and the build will continue and it will start compiling using all your available cpus

Here is what i usually change on the menu

Enable Preemptition Model for Low Latency (near realtime)

Processor Type and Features> Preemptiton Model (Preemtible Kernel(Low-Latency Desktop))

Please disable Xen

Processor Type and Features -> Paravirtualized Guest Support -> Xen

Proccessor Type and Features -> Timer frequency (1000HZ)
this is a for a desktop system

The latest deb package for kernel will be in /usr/src
you need to install it with

# dpkg -i linux-image*

upgrading from ubuntu 12.04 to debian testing or sid

A good idea is to install a light desktop manager like lxdm or xfce so at least you have a DM in case
gnome will not work out

Install debian keyring http://packages.debian.org/wheezy/all/debian-archive-keyring/download


modify /etc/apt/sources.list
delete all the lines and
add these ones 
deb http://ftp.us.debian.org/debian sid main contrib
deb-src http://ftp.us.debian.org/debian sid main contrib

apt-get update
apt-get -f -o Dpkg::Options::="--force-overwrite" dist-upgrade


there will be a lot of issues and it might bring your  machine unbootable
So be prepared with a testing debian stick or cd

Here are some of the issues that could happen while upgrading the machine there are many dpkg-new files in the /etc/init.d/ folder so here are some tips bellow

Init scripts and networking system
Get rid of upstart first. I had problems with sysv-rc and needed to force reconfiguration. Some init scripts were installed with "dpkg-new" in the name, I had to rename them. As with X, I tried few solutions, this is distilled but stil redundant version:

dpkg-reconfigure sysv-rc
cd /etc/init.d
mv acpid.dpkg-new acpid
mv anacron.dpkg-new anacron
mv atd.dpkg-new atd
mv cron.dpkg-new cron
mv dbus.dpkg-new dbus
mv module-init-tools.dpkg-new module-init-tools
mv procps.dpkg-new procps
mv rsyslog.dpkg-new rsyslog
mv udev-mtab udev
dpkg --purge --force-all base-files ifupdown initscripts netbase sysv-rc sysvinit sysvinit-utils
apt-get --reinstall install base-files ifupdown initscripts netbase sysv-rc sysvinit sysvinit-utils

The simplest VivaGraphJS graph test

Creating a graph in  VivaGraphJS with webgl

Create a graph with user id edges and for data

By definition, a Graph is a collection of nodes (vertices) and links (also called edges - identified pairs of nodes). In VivaGraph.JS nodes can be any object e.g. a string, a number, a function, another graph or object, and so on.

The graph g can be grown in two ways. You can add one node at a time:

g.addNode('1','User name 1');

g.addNode('2','User name 2');

Now graph g contains two nodes:1and 2. You can also use addLink()method to grow a graph. Calling this method with nodes which are not present in the graph creates them,If nodes already present in the graph 'addLink()' makes them connected

g.addLink('1', '2');

and at the end we add render loop

var renderer = Viva.Graph.View.renderer(g);

renderer.run();

here is the final output when loaded on the onload function for the html page , this is for the two users from above

we can add other nodes for example 3
g.addNode('3','User name 3');
and then create the links between them

g.addLink('2', '3');
g.addLink('3', '1');

Here is is howto upgrade to the new FDB 0.8.0 driver

How php compiles the source code ?

PHP compiles source code into Zend Engine bytecode - this is done by the Zend
compiler in zend_language_scanner.l, zend_language_parser.y and
zend_compile.c. This code is the executed by the opcode engine in
zend_execute.c and zend_vm_execute.h. The latter is generated from
zend_vm_def.h by means of the script zend_vm_gen.php.

For  a good intro to php internals there is a presentation in french 
http://julien-pauli.developpez.com/tutoriels/php/internals/presentation/

I saw it via this thread on php internals

RubyRails for PHP programmers starting points

If you have php code that needs to be converted to ruby/rails there are a few starting points
hyperpolyglot should be your homepage:
http://hyperpolyglot.org/scripting

On the ruby site there is a nice intro on Similarities and Differences.

From Rails for Php Programmers i used this pdf PHP to Rails Reference (extract)
on the translating php cookies and session (params for post/get ...)

Also the PHP to Ruby reference is very good
https://github.com/maintainable/php-ruby-reference

Ps: main site http://railsforphp.com/ seems to be down at the moment but i guess you can fork and build the reference yourself

new fdb firebird driver example :execute insert statement

Here is my example for inserting one row in firebird database with fdb python driver

Installing kinterbasdb on Ubuntu Server 12.04 64 bits (python 2.7.3)

 The official way is from svn , otherwise you will get this error

_kiservices.c: In function ‘_init_kiservices_ibase_header_constants’:
_kiservices.c:809:3: error: ‘isc_info_db_impl_isc_a’ undeclared (first use in this function)

Old driver and soon to be deprecated , the recommended way is to use fdb

svn co https://firebird.svn.sourceforge.net/svnroot/firebird/python/kinterbasdb/trunk/ kinterbasdb
cd kinterbasdb

sudo python setup.py install

Connect to firebird using the new python fdb driver

Install the firebird driver (you might need firebird2.5-dev headers)

 pip install fdb

use this documentation link  for the moment

Timezone offset in seconds php vs ruby

echo date('Z');

10800

and timizone seems to be set right


date_default_timezone_set('Europe/Bucharest');echo date('Z');
10800

and in ruby it gives


Time.zone.now.utc_offset()
 => -25200


seems that rails and php lives in different timzones

so try to use localtimezone and is correct now


l = t.getlocal
 => 2011-06-27 10:10:00 +0300
1.9.2p318 :025 > l.gmt_offset
 => 10800

Firebird remote interface vs direct file access for firebird databases

The scenario it can happen when using firebird classic (see the end of the article) You skip the remote interface (tcp/ip) and access the database directly by typing

isql-fb database path

here is my setup when i try to use the database directly or without password the server is not using the remote interface (There is no remote server/interface in the show version command)

sudo isql-fb /var/lib/firebird/2.5/data/rubyonfire.fdb
Database:  /var/lib/firebird/2.5/data/rubyonfire.fdb

SQL> show version;
ISQL Version: LI-V2.5.2.26466 Firebird 2.5
Server version:
Firebird/linux AMD64 (access method), version "LI-V2.5.2.26466 Firebird 2.5"
on disk structure version 11.2
quit;

check if the server is up with telnet localhost 3050 and then force the tcp ip method to connect using the remote interface use locahost:path 

SQL>connect "localhost:/var/lib/firebird/2.5/data/rubyonfire.fdb" user 'SYSDBA' password '********';

SQL> show version;
ISQL Version: LI-V2.5.2.26466 Firebird 2.5

What you can learn from instagram deal and become a billionare

If you look at the tech behind it:
- use Ubuntu server or debian on amazon ec2 (I guess you can choose your own cloud solution)
- use Django with a shraded relational database (I would chose firebird)
- use nginx with gunicorn or uwsgi
- you use memcache right ?
- for notifications on apple use pyapns , billions of messages are send with it
- create and write a android app
- use gearman
- redis
- scare the hell out of facebook

[Sun Mar 25 21:15:42 2012] [error]   DeprecationWarning

so i have deleted the line ADMIN_MEDIA_PREFIX from settings.py and need to configure the "/media" for the admin url also replaced

CACHE_BACKEND = 'locmem://'

with

{
    'default': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
    }
}

EC2 is about 10-20 times more expensive than dedicated hosting.

Quote of the day via ycombinator:

Even if reserved instances save us 22% over 3 years, it still doesn't even come close. Reserved instances also force me to commit to using a certain type of EC2 instance for 3 years with lots of money upfront. Moreover, IO is ridiculously bad on EC2 and there's nothing that can be done about it. Even RAIDing a gazillion EBS volumes together doesn't do much. I'm glad the truth about how expensive EC2 really is is starting to come out. Hopefully it will force them to revise their pricing, or at least offer more processing power for the same price.

I ran some benchmarks a few weeks ago that show how expensive EC2 really is

Agreed. Here's a good relevant blog post by mark maunder challenging the "cloud hype"  http://markmaunder.com/2011/10/31/clouded-vision/

Another thing that is overpriced is the memory , here is a quote from the basecamp's next memory cache article (see the comments section)


They have brought 864GB of RAM that looks like below

Total price was $12,000
Compare that with Amazon :Just checked AWS Elastic Cache’s pricing.
It would cost around 20k / month for ~ 800 GB of Memory. (12 * Quadruple Extra Large nodes / 68 GB)

Suhosin is disbled by default in Debian, and soon Ubuntu - i hope

I think is the right aproach 

I don't believe in security by obscurity (this random patch it will secure your php ... riiight)

suhosin shouldn't be a patch it should be inside of php core or as module (think like the selinux situation) , So debian guys are right use the upstream unpatched version , let the core php devels decide if suhosin is right or wrong for them :less bugs , less patches , life is better = more security and fast updates in debian

Did i told you that upstream doesn't test suhosin patch when they run the tests ?
And with that patch php core is not the same , there are some bugs that i found related to it  (in debian/ubuntu) and it happens only when that invasive patch is applied

updating passenger in rails and ubuntu 10.3 lts

I had one issue with an old instalation of passenger and nginx (kernel 2.6.32 doesn't quite deliver signals to the nginx 0.8.x)

I download the current dark passenger

wget http://rubyforge.org/frs/download.php/75548/passenger-3.0.11.tar.gz
tar -zxvf passenger-3.0.11.tar.gz
cd passenger-3.0.11/
rake package
sudo su # and make me a sandwitch

cd pkg
gem install passenger-3.0.11.gem

start the nginx wizzard

/var/lib/gems/1.8/gems/passenger-3.0.11/bin/passenger-install-nginx-module

choose (1),(1)
enter enter enter
and all is installed

Read what is needed to add to nginx config if you do an upgrade

mainly the new passenger path

Please edit your Nginx configuration file (probably /opt/nginx/conf/nginx.conf),
and set the passenger_root and passenger_ruby configuration options in the
'http' block, like this:

  http {
      ...
      passenger_root /var/lib/gems/1.8/gems/passenger-3.0.11;
      passenger_ruby /usr/bin/ruby1.8;
      ...
  }

After you (re)start Nginx, you are ready to deploy any number of Ruby on Rails
applications on Nginx.

Press ENTER to continue.

encoding decoding strings in python3.x

I like to think of  encoding of strings in python3 to the analogy of encrypting your plain text into a random stream of bytes

string (plain text) -> encode (encrypt) -> bytes (stream)
bytes (stream) -> decode (decrypt) -> string (plain text)

and the codec you choose is your key (utf-8 ...)

Typing so many times the password in sudo is good or bad ?

Well if you watch National treasure  you will see how easy is to spot the common keys that you press with a special fluorescent/UV light , also the fingerprints on a keyboard are more visible on thouse keys (that would be the keys for sudo for example , or the login window) also some social engineering helps (knowing the person)


- I'm here.
- Give me the letters for her password.
What do you got for me?
Hit me with it.
A-E-F-G...L-O-R-V-Y.
Anagrams being listed.OK.
Top results: "A glove fry."...
...
- It's "Valley Forge"."Valley For..."
I don't have that on my computer.It's "Valley Forge" -she pressed the E and L twice.
Valley Forge was a turning pointin the American Revolution.C
an I marry your brain?
We're in.


That is why is better to use the ssh-agent , password-less sudo
and spread your password keys over your keyboard , and one more hint
it shouldn't be any reference to anything known about you in public/private life (eg if you love history:historical references with years dates , places)

Ubuntu Romania and Libre Software Romania (software liber) are against ACTA

Between revolutions we have to fight ACTA too , I will copy paste the message from Stas

Apparently, while most of the Romanians were busy with „Băsescu” crisis and snow, ourgovernment decided to sign ACTA.

To be honest, I’m not sure who’s job was to inform European population about this upcoming decision, but they did it in the worst possible way. Anyway, if you feel the need of blaming your regional/representative politician, you can get his address from here:agenda.grep.ro.

For those who just woke up in this world, and have no clue what’s this all about, take a look at this video.

Configuring pydev for django

I love some of the pydev features and here is my usual django/python setup

Install eclipse classic

Configure updates and add pydev

Configure updates and add eclipse themes

Install ipython
sudo easy_install ipython

Create or import pydev/django project

Configure java script editor (WTP webtools) in updates (in my case for indigo , choose from the repository manager in updates)

Learn and configure howto do remote debugging for django

The eclipse git plugin it crashed on me , aka it failed when i tried to do a push
It's slower than the c based implementation (eclpise plugin for git is written in pure java )
Did i told you that doesn't work , ok So you need to use command line for git , it's faster and better

Why Zope fails and Django is better

I quote a thread from reddit and if you still use zope/plone you fail , there is nothing pythonic in the zope

I did a beginner mistake once to think that zope is somehow python and i could handle all the complexity and zope core ugliness but now I know the complexity monsters can't be tamed (include there XML , JAVA2EE, zope ... )

As a Python programmer, hardly anything you knew was useful when trying to do stuff in Zope. It was its own universe, with its own physical laws. You could do some simple things via the web interfaces, but as soon as you want to do stuff in Zope's odd variant of Python, you had to start from scratch.

And as a result, we lost a whole generation of Python web programmers.

In that respect, Django is more of an anti-Zope -- it's plain old Python pretty much all the time, you don't have to unlearn or relearn anything, and it has done more to get new programmers to pick up Python than any single Python library or application ever released before it. Heck, the Django mailing lists are almost as crowded as the Python mailing lists these days.

Debugging tips for #perl tfmail.pl on a shared host with no logs , and windows on it ...

Well the story is that the tfmail.pl shows only this
Application Error An error has occurred in the program so no debug errors or anything else
I had to add debug mode for the script and saw this tip how to do it :

With Perl there is something you can try that will attempt to redirect error messages to the browser so you can attempt to diagnose the problem. Open the script in your text editor, and under the path to Perl on the first line, place this:

use CGI::Carp qw(fatalsToBrowser);

Only then I saw that LOGFILE_ROOT was set to '.' and that made the script die I have fixed the line

use constant LOGFILE_ROOT   => '';

and reuploaded and all was ok after that

Bloody Happy New Year

The last year , what i can say
One of my Childhood friends is Dead : Teodor Marian
I still don't know if he wanted to be a Priest like his father or if it was better for him to be a teacher
Before he Died (one week) i had this dream of playing around his House and i couldn't understand what is all about (I felt like someone from my family will Die).
I still can't find his Childhood face in my memory , Maybe is my Trauma that forbids access to it , I only rember his happy laugh and happy pieces of that period
The father of one of my coworkers is Dead
The New Year :
The Father of one of my coworkers is Dead
The Siamese Fish is Dead
The Sanitary Fish is Dead
All in All no matter how many walls you rise against the world there is something to shake the entire fundation
But now i feel better , life goes on and I know that there is something better than to dive into melancholy
I go back to ther roots , I love programming in Python , Pascal or any language
I still have one happy family at reea.net , i still have my Love and my future wife
I still have my Family near me even if they are so far away
Ohh Yes and still have the Exams this Month :)
There is always something (level of stress or excitement) that keeps you alive and kicking

My FSocial Network

Here is how my FNetwork looks like bellow The only observation I'm mostly strongly connected with coworkers , that means that i use the network for coworker notifications or maybe i'm workaholic :) I wish the visualisation was made with webgl

One way to run firebird pdo tests

Just to not forget how to run them i write here

I had problems with burning dvds both with xfburn and with brasero too

One of the errors  was

Another problem was that burn completed the writing in xfburn but when reading and checking the md5 for the dvd

Replacing gnome3 with xfce/lxde on #fedora core 16

To replace and remove the ugly gnome 3 interface from fedora core 16 (it doesn't work if you don't have hw 3d acceleration if you are on a remote vnc session ) and to enable something more light and classy

you need to do the following easy steps

(it's better to do it in a console)


yum groupremove 'GNOME Desktop Environment'
yum groupinstall XFCE
yum groupinstall LXDE




create the file with a editor
/etc/sysconfig/desktop

DISPLAYMANAGER=/usr/sbin/lxdm
PREFERRED=/usr/bin/startlxde

and reboot


to enable vnc session for remote users
/bin/su username -c "/usr/bin/vncserver :1 -geometry 1440x900"



also it can be added in the rc.local so they will be enabled at server startup

/bin/su username2 -c "/usr/bin/vncserver :2 -geometry 1440x900"
/bin/su username3 -c "/usr/bin/vncserver :3 -geometry 1440x900"
....

Volumeicon +xfce-mixer part two : better volume applet in #lxde for !debian or #Lubuntu

Dedicated to Jancsi who just switched from unity to Lubuntu

As you might now from part one i use volumeicon for controlling my speakers when i listen to music
There is no easy graphical mixer in lubuntu but
There is the help of xfce4-mixer to the rescue



open console and type to in

sudo apt-get install xfce4-mixer

next install and compile volumeicon with the patch to use xfce4-mixer by default
it places an icon in status bar and when you right click you can choose mixer and it will show you the xfce4-mixer in all it's glory

git clone https://github.com/mariuz/volumeicon.git
cd volumeicon

sudo apt-get install libasound2-dev
./configure --prefix=/usr 
sudo make install

I have two soundcars so i have added in the config

cat /proc/asound/cards
0 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfeaec000 irq 44
 1 [default        ]: USB-Audio - Microsoft LifeChat LX-3000 
                      Microsoft LifeChat LX-3000  at usb-0000:00:1d.2-1, full speed

vi ~/.config/volumeicon/volumeicon
[Alsa]
card=hw:1

Start volumeicon or add it to the startup session

volumeicon &

if you are on pure LXDE/Debian

editor ~/.config/lxsession/LXDE/autostart
#add to the file
@volumeicon

If you are on Lubuntu

editor ~/.config/lxsession/Lubuntu/autostart
#add to the file
@volumeicon

by default when you click on volume icon it mutes the sound card so in preferences i put Left Mouse Button Action to open the Slider And the Channel will be PCM

LightDM on Xubuntu 11.10 horror story

I have installed xubuntu 11.10 on one machine that was already with kubuntu installed on it
after reboot there was nologin only some flashes
I have disabled graphical boot , deleted quiet and all the pretty options in the grub menu (nomodeset added too)
no luck
removed kdm still no luck
I have launched lightdm manually with debug flag
lightdm -d and saw that it needs unity-greeter and there was no such thing as unity-greeter installed
so i have installed it  and changed to the classic gtk greeter
In /etc/lightdm/lightdm.conf i have changed
greeter-session=lightdm-gtk-greeter

Reboot and still in the logs i saw "lightdm main process  TERM signal"
and No greeter .
What is weird that lxdm started if launched from command line also
the start-xfce4 worked ok
what to do ?
i have added in rc.local
start lightdm and after reboot
the login was ok again

Installing qxl drivers on Windows7 guest (and others virtio drivers for ballooning memory, virtioserial, network and viostor)

Download qxl driver Windows qxl driver qxl-0.10-20112808.zip

extract it  then install it

cd x86
pnputil -i -a qxl.inf


from the downoad page also you need to install spice vd-agent Windows guest agent - vdagent-win32_20111124.zip



Last thing you need to do is install the virtual desktop agent for your windows 7 guest. To do this, copy the two executable files from the vdagent zip file 

Now go to the directory where these executables are located and type “vdservice install”. This will install and start the guest agent service as shown below.

You might need  virtio drivers 
The drivers include virtio drivers for ballooning memory, virtioserial, network and viostor ( block drivers ). These drivers are signed but not WHQL and there are no gui installers for them.


This is the installation method with virtio drivers :
Download the the host the iso.
Mount the iso in the windows guest machine from the the virt-manager details interface


and for each inf install it and then configure the machine to use the virtio


d:\
cd Windows7 
cd x86 
pnputil -i -a *.inf

Ie9 on kvm-linux

The steps/scripts for using ie9 test machine are quite easy to follow if you are using virtualbox
but what about kvm-linux ?


I followed the guide to make vhd to kvm raw This guides works but it creates a raw partition of 127G in size so is not so good :
qemu-img convert -f vpc -O raw Windows\ 7.vhd Windows7ie9.img

 so i used this command line instead:

 qemu-img convert -f vpc -O qcow2 Windows\ 7.vhd Windows7ie9.qcow

and image is now ~ 13G
Create new virtual machine importing the converted qcow2 image

Notice I had an issue with the tablet device so i have disabled it for vnc

You can add montly script in scheduler to rearm it on the windows guest
rearm.bat
slmgr –rearm
shutdown -r -t 0

Next i had some issues with vnc (mouse positioned weird and at the distance with the vnc cursor when connecting from remote)


and I have enabled the spice server instead of the vnc one in the virt-manager configuration for this host and then installed spice client on my machine

sudo apt-get install spice-client

run it with

spice-client
type host port and password if you have one set

To Exit the spice client Shift - F12

Correcting #ubuntu Unity mistake - move it at the bottom

I use Lubuntu or Xubuntu and i have read that the problem with the unity on the left side can be easily fixed
I think no one would complain if the bar would be at the bottom with a proper classic start menu (win7 style) isn't it ? and yes with the close buttons on the right please

ps : I have enough pixels or two monitors to put unity wherever i like and want , that is the cost of freedom

My next phone will be with Debian / Ubuntu

This ubuntu phone art concept made me think that i really want a Linux phone based on Debian/Ubuntu
I don't want a Nokia zombie all i want a true open source phone (true in the heart and true in the ubuntu spirit)

#Ubuntu After the uTorrent page was virused i recommend QBittorrent to anyone

I'm pissed utorrent doesn't make a client for Linux until the endof the year (only next) but in a sense we Linux users don't really care , there are many torrent clients to choose from One that i love is qbittorrent. It works great on all platforms , it is written in QT framework and it looks and feels just like uTorrent minus the crappy bars and viruses Did i mentioned that is small and better in the sense that is simpler to use than kTorrent (starts in < 1s instead of minutes) And it does have a cool logo too

In ubuntu you can install this way

 sudo apt-get install qbittorrent

 or on windows/macosx from this page

Php Image Slow SMP Magick on #Ubuntu / #Debian

There is a known bug with Image Magick : it can be very slow when used with openmp enabled (by default in debian/ubuntu) on multicore systems (almost on all servers these days) It is eating a lot of cpu (50-100% for each core) instead of idling at 1-2% (for simple image manipulations) It was strange for me that one single core server was faster than a quad core in the same specs with the rest of the config (os ubuntu 10.04 lts, kernel latest, ioscheduler : deadline) Eliminating the problems on what could slow down the server (php version , image magick version , kernel version ) the only thing left was cpu Solution is very simple configure imagemagick without openmp

apt-get buil-dep imagemagick
apt-get source imagemagick
cd imagemagick-6.5.7.8/
sudo vi debian/rules

add ~ line 39 --disable-openmp (dont' forget to add \ to the privious line)
it should look like

       --x-libraries=/usr/lib/X11 \
        --disable-openmp

Rebuild the package and reinstall

dpkg-buildpackage -b
sudo apt-get remove --purge libmagickcore2
cd ..
dpkg -i libmagickcore2* libmagickwand2*
apt-get install php5-imagick
/etc/init.d/apache2 restart

Where the rock stars go when they go down ? they go to country hell

My biggest wtf moments were when i saw that Robert Plant is singing and dancing country music I wondered for months and years how that could that happen ? how he can go so low After so many great performances in rock concerts . While listening to many Blues Bands i observed that many songs were ripped by Led Zepelin and others so in the end Led Zeppelin is one of the best Cover Bands of them all This why the main lead singer can go so low , he can play anything even country music (no sacrifice or spells were involved in the process)
