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.

Illegal parameter: -WG while switching project from free pascal 2.4 to 2.6

While switching compiler from 2.4 to 2.6 under debian sid i had this error whilile
compiling an project created under ubuntu with lazarus 0.9.30.x and fpc 2.4

Illegal parameter: -WG




Solution is to remove : Target OS specific options (Win32 gui application -WG) from Project Compiler Options

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

TEST_PHP_EXECUTABLE=auto php -n ./run-tests.php ext/pdo_firebird

of course you can add username/password , db path

PDO_FIREBIRD_TEST_DSN='firebird:dbname=/var/lib/firebird/2.5/data/employee.fdb'
PDO_FIREBIRD_TEST_USER='SYSDBA' PDO_FIREBIRD_TEST_PASS='masterkey'
TEST_PHP_EXECUTABLE=auto php -n ./run-tests.php ext/pdo_firebird

Saw it via comment section from pdo firebird driver documentation

php doc team docbook editor is pretty cool

We want something like this for firebird doc team :) Here is one shot with the documentation writing online, no need for other xml editors

wodim saved my day and wrote the xubuntu 64 bit iso at last

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

One of the errors  was
SCSI error on write(0,16): [3 73 03] Power calibration area error

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

Now i can go back to [Eric Clapton] Cocaine

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

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)

MSI MS7528 (G31M3 motherboard) bios update Linux horror story

I had this error on dmes log output BIOS bug: CPU MTRRs don't cover all of memory, losing 768MB of RAM Solution is to upgrade the bios fro v1.1 to v 1.3 1.After i have searched the motherboard on msi site i didn't knew where is the generic motherboard (without F/L) and it seems that according to the forum All I can see are the -F and -L(S) models. It's almost as if the plain G31M3 does not exist. and if you like to know why doesn't my board have the -F printed on it:"-F" is ommited. G31M3-F or G31M3 means the same board
2. Flashrom from linux doesn't work yet with this board
3. Next instal windows (yes you read that is right) and use the useless Windows tool Live update 5 that doesn't work at all (it doesn't find the drivers, it doesn't find the bios update)
4. I need to put another tool that it will install DOS ! and then put the zip with the bios on an usb stick
5. I had to run fix it to redo the drive geometry also i had to format the usb stick
6. Required Boot from ubuntu live cd and remove windows (optionally format usb stick as ubuntu live cd)
check the bios and dmesg log

#Oracle Thank you for killing #mysql with opencore=propietary licence and pushing for alternatives

The LAMP king is dead and is  Open core = Closed source http://ur1.ca/0dahc , so is time for Mysql alternatives : Firebird


Monty's words
Oracle has now officially announced that MySQL is not a full free software project anymore and that they will go for an Open Core model.

This is inconsistent to the original MySQL business model. The main strength of MySQL has always been that all MySQL source code was freely available. It was thanks to this that MySQL got widely adopted and got to be used by tens of millions of users.

This was a fact that the MySQL board and Sun understood. Closing the MySQL server code base in any manner would be bad for long term business.
So what's so wrong with Open Core?

As a business model, especially to bootstrap a business, Open Core is not a bad idea. It gives you some leverage with your users to get part of your development paid for. This is however done at the cost of fewer users and a less adopted project. Many projects however abandon Open Core models when they grow as open source gives them more users and thus more value.

What is most important to understand about an Open Core project is that it has nothing to do with an open source project. If you are depending on a single closed source component then you have to regard the whole project as a closed source project as you lose all the benefits of open source:

• You are depending on one vendor.
• You can't do any bug fixes yourself and you can't contract anyone except the original vendor to get things fixed.
• You can't examine and improve the product (not any part of if).
• You can't use any open source or commercial extensions from anyone else. This is true also for any plugins that access any internal parts of the product (which is true for most MySQL plugins).
• You are limited to the platforms that the original vendors makes available. (In MySQL's case you can't for example use the new commercial features on RedHat 6 as it's not a supported platform).
• The builds you are using are not tested anymore by millions of users (more bugs).
• The product is not checked by the open source community for security problems or back doors.
• The new features will not be adopted by (and may even cause conflicts with) other open source projects.
• You are subject to one vendor's price politics which they can change at their convenience.

What is interesting with the new commercial features is that parts of them where not developed by Oracle. The thread pool was originally developed by Ebay for MySQL 5.0 and contributed to MySQL to be include in MySQL 5.1. Only the new scheduler interface code was added to MySQL 5.1 while the thread pool itself was added (but accidentally with a slower implementation) into MySQL 6.0. Oracle never back ported the thread pool code to the MySQL 5.5 community version and now also the MySQL 6.0 tree is deleted.
The new pluggable authentication, which makes the new PAM authentication possible, was developed and contributed to Oracle by Sergei Golubchik at Monty Program Ab.


Alternatives and the good News 


These words are prophetic and the decline started to happen 


The decline will not be immediate, it will take some time, notably Apache distributions like XAMPP and WAMP will have to offer users alternatives to MySQL, as most developers use these packages, instead of installing products independently. All is not lost, the Open Source community has plenty of options. There are two well established alternatives to MySQL: PostgreSQL and Firebird. Both have large established communities, and support of major corporations. One of these will become the next MySQL


I put my vote on Firebird SQL : it is lighter and it is easier to maintain (drop in replacement for mysql in lamp installements)

From Marco Cantu’s blog:

Now, this could be a very good opportunity for all of the other open source database servers (and also some of paid ones!), particularly the most popular ones like Firebird and PostgreSQL. I’m particularly fond of Firebird (the InterBase offspring) and use it in many projects and did a lot of consulting to Delphi developers using it. Can this be ? MySQL with its huge popularity has certainly obscured it, so it could be a good time to act.

fixing nginx 1.0.x and html5 video

Fixing nginx 1.0.x to make it serve video ogg correctly Open up the Nginx mime type configuration file, eg: /etc/nginx/mime.types Add these lines after the last video mime type

video/ogg                             ogm;
video/ogg                             ogv;
video/ogg                             ogg;

The best definition for clould computing

Definition was given on slashdot
Unfortunately, the sort of seamless network-agnostic computing Plan 9 and its descendants enabled is now a commercial threat to all the other players in the mobile space. Half the point of the "cloud computing" trend is to lock people in to one provider's weakly interacting web service, and, by extension, into the controlled ecosystem of third-party services that do interoperate well with it. Plan 9 is too good at what it does to be successful.

All cloud providers want to hook you up to the system and then rip you off with computing time , bw or with overpriced NO uptime like amazon does with their constant service disruptions
No wonder they all want to move you to the cloud and milk you as much they can .
I have tested RDS on Amazon is is absolutley horridly slow compared with a fine tuned machine

Rip Google pack time for librepack

Rip google pack i didn't quite loved you because you contained mostly propietary crap : adobe reader, antiviruses , antispyware , the pesky google desktop and firefox with google toolbar included (by the way i think toolbars should be forbidden in all browsers just to make the world a better place) but I always recommended google pack to people still stuck in the past and windows land (minus the real player that is contained in the pack !)

Why :it updates automatically the programms and contains antivirus / antispyware , maybe is time for a librepack that it will contain : vlc ,libreoffice , clamav, firefox, chromium using the same update method used by the google pack http://googlesystem.blogspot.com/2009/04/google-update-open-sourced.html I almost wish to create it myself but the devel setup is quite heavy

dist-upgrade in #ubuntu hardy on Amazon ec2

Today i have upgraded hardy machine with latest patches on an Amazon ec2 machine (related to httpd bug)

First download the libc6-xen
and install it with 
dpkg-i 
then remove the libc6 and ubuntu minimal 


dpkg -r libc6-i686 and then dpkg --configure -a

necessitas setup and test raycasting #QT demo on #android

I wanted to test the qt raycasting demo on my android and here are some steps and missteps that i have done in my research

I follow the sdk instructions from here

http://sourceforge.net/p/necessitas/wiki/How%20to%20install%20Necessitas%20SDK/

Download necessitas sdk for me is something like necessitas-0.2.1-online-sdk-installer-linux

chmod +x necessitas-0.2.1-online-sdk-installer-linux
./necessitas-0.2.1-online-sdk-installer-linux

I have enabled all options to be downloaded even the android ndk/sdk
my path is something like /home/mariuz/work/necessitas

Setup finished and downloaded all the files
next is to configure the qt creator
http://sourceforge.net/p/necessitas/wiki/Setup%20QtCreator/

The only changes that i needed to do is to add ant path in (is custom downloaded from apache.org and unziped in /opt)

Tools -+- Options -+- Android -+- Ant location : /opt/apache-ant-1.8.1/bin/ant

The other are left untouched
I have loaded the raycasting example
but i get an error and even if i downloaded the Ministro app from the google market (and QtCore is installed)

Starting remote process ...
Can't find eu.licentia.necessitas.industrius.example.raycasting process

Seems that :
The libraries downloaded by Ministro are different from the libraries in the Necessitas SDK (the dynamic linker in the emulator had problems that were fixed when I overwrote the Ministro libraries with the (stripped) libraries from the Necessitas SDK) – is this a known problem and will it be fixed?


So i have checked to deploy and copy the necessitas libs to the target when i run the app
but again it failed

Read the section with local libs
So i started clean with the smallest qt demos (simple editor with menu that comes with qt)

The secret to start it is to make sure for emulator that arm5 is choosen
also the run Project options should contain that necessitas libs should be delpoyed with the project at once

After that i did rebuild project and run
voila

After that i have tested the raycasting using the same staps as above arm5+ delploy local qt libs +use local qt libs
and it ran !

It started on sony xperia 8 but of course there is no buttons setup , and this should be the part two of the article :)

250 lines of Qt C++ code for Wolfenstein-esque of raycasting (labs.qt.nokia.com)

I saw this tweet about an old qt raycasting example running on nokia  

code is in graphics dojo

git clone git://gitorious.org/qt-labs/graphics-dojo.git
cd graphics-dojo/raycasting
qtcreator raycasting.pro

press run

You can inspect the code directly on gitorious

I will try to see if it works on my android using necessitas

Going back to #Debian testing is easy

I had some problems with latest cups in debian 1.4.8
so i have removed the cups from synaptic and wanted to switch back  to a more stable env

replace the unstable string with testing in

cat /etc/apt/sources.list
deb http://ftp.us.debian.org/debian/ testing main
deb-src http://ftp.us.debian.org/debian/ testing main

deb http://ftp.us.debian.org/debian/ testing non-free
deb-src http://ftp.us.debian.org/debian/ testing non-free

deb http://ftp.us.debian.org/debian/ testing contrib
deb-src http://ftp.us.debian.org/debian/ testing contrib

record all the packages that you have for posterity

sudo dpkg --get-selections > dpkglist.txt

remove some packages that offend your desktop eg some gnome3 ones or cups

then is time to restore the package list as it was before removal and update

sudo dpkg --set-selections < dpkglist.txt
sudo apt-get -y update
sudo apt-get dselect-upgrade

Now is time to reinstall cups

sudo apt-get install cups hplip
