By the time I wrote this rticle, Adobe placed a notice that they will no longer continue with the Flex Builder development. This means that you can only use command lines to work on Flex. I guess this will affect FB4LINUX.
I refer to a number of sites before starting the installation and found one worth mentioning here. Matthew wrote with clarity and did cover what most other instructions provided and maybe a bit more.
Pre-installation checks: Have you installed Eclipse 3.5+ and Java Development Kit 1.5+
Step 1. Download the fb4linux files in 4 parts from http://code.google.com/p/fb4linux/downloads/list
cat FB4Linux* >FB4Linux.tar.bz2
tar -xvf FB4Linux.tar
I renamed the folder to Adobe_Flash_Builder4 since I did not want spaces between the folder name.
Step 2. Download the eclipse plugin for FB4Linux from http://www.brighthub.com/hubfolio/matthew-casperson/media/p/78806.aspx
Unzip the file ecplise and copy the plugins to /usr/lib/eclipse/plugins
The plugins are;
Step 3. Start Eclipse and apply the plugins.
In Eclipse select Window->Preferences->General->Capabilities and make sure that the Classic Update option is checked.
Click Help->Software Updates->New Feature to Install.
Click the New Local Site button, and type in the location where you extracted FB4Linux in step 1 (you will need to specify the eclipse subdirectory to be specific).
With the Adobe Flash Builder 4 site selected, click the Finish button. You will be asked which features to install. Tick the Adobe Flash Builder 4 feature and click Next.
Accept the terms and click the Next button and click Finish button.
Step 4: Install the Flex SDK from http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4
Download and extract a copy of the Flex SDK from Adobe into a folder flex4.1.0
Set Eclipse to use the Flex SDK by right clicking on your Flash project and selecting Properties. Select the ActionScript Compiler option.
Click the Add button to add the location of the Flex SDK you have extracted.
Click on the Run toolbar menu item and select the External Tools Configuration option.
Right click on the Program option and select the New option. Then fill out the Location and Arguments settings to point to your Flash standalone player and SWF file respectively.
Done...next to look for more flash tutorials.

Open source licensing is now showing how main stream OSS products can be shifted if those in control is not respected. The OpenOffice.org (I hope this name wont be part of power tussle) is now looking at a branch off called Libre Office. Though its in Beta but I expect lots of the bugs I am facing with the present OpenOffice.org provided by the long term support version of Ubuntu 10.04 to be fixed.
Most notable is the page numbering of the slide handout in Impress. Impress is still showing page 1 in the footer for all pages in OpenOffice.org 3.2.1.
Currently all testing packages of the first Libre Offfice can be found at http://download.documentfoundation.org/libreoffice/testing/
From what I have read, looks like this will override the OOo in Windows but should co-exist with OOo in Linux. I will update this page with progress I make in installing the Libre Office(beta) 3.3. The Java Runtime Environment (JRE) 6 (size of upto 92Mb) needs to be installed before installing the Libre Office. This can be done with synaptic or at the command prompt type
sudo apt-get install openjdk-6-jre sun-java6-fonts icedtea6-plugin
Step 1: open a terminal prompt. Download the Libre Office (LO) which is about 150Mb with either of these commands;
Step 2: Extract the tar.gz
Step 3: Switch to the folder en-US then install the DEB packages
sudo dpkg -i DEBS/*.deb
sudo dpkg -i DEBS/desktop-integration/*.deb
Internet crawling so slow. Will Unifi change things?

- When I create a macro to delete selected cells, it does not work. (Solved on 3.2.1)
- Impress printout of handouts, I do not get the page foot numbers. All pages display as number 1.
Backup all of the extensions you have for OpenOffice.org 3.2.0, if you intend to use it in the future. Now, the steps to upgrade to OOo 3.2.1
- Download OOo 3.2.1 from
- Open a terminal line and extract the tar.gz file
tar -xzvf OOo_3.2.1_Linux_x86_install-deb_en-US.tar.gz
- Remove existing OOo 3.2.0
sudo apt-get remove openoffice*.*
- Enter the extracted directory and install the .deb files
sudo dpkg -i *.deb
sudo dpkg -i desktop-integration/
- In the software sources, enable the "software Sources"
- Update packages and install OpenOffice.org-3.2.1
Tuesday, September 28, 2010
One way to avoid this is to disable the auto update. Since it is a lab environment, I can easily delete and replace user1 account to remove previous configurations in OOo for user1.
Step 1. Create the 2 simple scripts to disable the auto update and reset the desktop for user1.
echo "Resetting pc:"
chkconfig yum-updatesd off
tmpwatch 0 /tmp
echo "Creating user user1"
userdel -r user1
useradd -m user1
echo "User created, going to reboot"
echo "Enter server name:"
if [ -e $SERVER ]
scp prepare-cooomb-test.sh root@"$SERVER":~
ssh root@"$SERVER" ./goreset.sh
echo $SERVER >> $LOGFILE
Step 2. execute (run) the script named startscript.sh
Wednesday, September 15, 2010
Step 1: Open a terminal. Or through the Kpackagekit, install packages below.
Step 2: Install packages by the command below;
sudo apt-get install libmpg123-0 libwbclient0 samba-common smbclient ttf-symbol-replacement winbind wine wine1.2 wine1.2-gecko pptview
MS PPTX and DOCX files can be viewed with OpenOffice.org 3, or the viewers from MS Office (I am yet to try these 2).

The most likely cause is that Gnome's GVFS is running and opens the disk automatically. Doing a "ps aux" you will find the following processes running;
/usr/lib/gvfs/gvfsd-trash --spawner :1.39 /org/gtk/gvfs/exec_spaw/0 /usr/lib/gvfs/gvfs-gdu-volume-monitor /usr/lib/gvfs/gvfsd-burn --spawner :1.39 /org/gtk/gvfs/exec_spaw/1 /usr/lib/gvfs/gvfs-afc-volume-monitor /usr/lib/gvfs/gvfs-gphoto2-volume-monitor /usr/lib/gvfs/gvfsd-metadata /usr/lib/gvfs/gvfsd
What is GVFS?
GVFS replaces Gnome's virtual file system (VFS). Programmes built with the library GIO or Gnome I/O will be invoke automatically and managed by the gvfsd service.
The gvfs-fuse module is used only when the application is not built with the GIO library. With GVFS, Nautilus takes over the automount/autorun responsibilities from gnome-volume-manager. A good read on GVFS is in this 2006 article.
If I stop (kill) the gvfsd and gvfs-gdu-volume-monitor, Nautilus does not get open anymore. But instead of killing this process, I will approach this by assuming that gvfs reads from Gnome Desktop Manager configuration files.
Open a terminal (e.g. konsole) and type
In the left window of Gconf-editor, choose /apps/nautilus/preferences and remove check mark for
Close the Gconf-editor and log out. After you log back in, no more Nautilus.

Install Eclipse and the java base (about 256Mb)
Ubuntu 10.04 provides Java6 in the form of OpenJDK (openjdk-6-jdk). This is great for developers, but for those who wants to install Sun (Oracle) version of Java6, I will also provide the steps here
A) Install OpenJDK (check if its already installed before doing this!)
Step 1: open a terminal and type the following;
update-alternatives --query java
If you already have OpenJDK, then you do not need to install it anymore. If you do not have any Java JDK listed, then continue to step 2.
sudo apt-get install openjdk-6-jdk openjdk-6-jdk icedtea6-plugin
B) Install Sun (Oracle) Java JDK.
Step 1: Add the repository for Sun Java. Open a terminal and type the following;
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
Step 2: Install the JDK along with the plugin
sudo apt-get install sun-java6-jdk sun-java6-plugin
Step 3: Make it your default
Sun Java is now installed, but you need to make it the default java to use:
sudo update-alternatives --config java
Open a terminal and type;
sudo apt-get install eclipse eclipse-pde eclipse-jdt eclipse-plugin-cvs
Install Android plugin for Eclipse
Refer for details at Android.com
Download and add the Eclipse plugin for Android by (update 15 Feb 2010)
previous post was;
$ wget http://dl.google.com/android/ADT-0.9.7.zip
The tgz is for the android SDK.

1. Installed via the terminal
sudo apt-get install moonlight-plugin-mozilla
Still cant work...maybe its Mono 1.0?
2. Installed the Mono 2.0 via URL http://go-mono.com/moonlight/download.aspx
Still cant work!
3. Installed the prerelease Mono version 3 via the URL http://go-mono.com/moonlight/prerelease.aspx
The size was 13.2Mb
Still cant work! Firefox keep closing (crash) each time I click on that page.
I am sending rwgenting a feedback.
Those websites who choose to use the .Net framework keeps most Linux users away from their services. Unless there are plans to get these fixed. If anyone have gone to rwgenting to do booking of shows on a Linux machine and it works, do let me know how it can be done.

Next, AVIs are great for the PC, however, to distribute to people who do not use PCs to watch movies or just to have a larger screen, it is better to convert the AVI into a VCD.
Step 1: Copy the files from the AVHCD camera
Step 2: Convert to AVI.
Future action can consider direct preparation for MPG. Here it is in AVI because there was a need for me to prepare in various format apart from MPG or VCD.
- File -> Save As ->
- Project -> Add clip
- In the Project Tree window, drag the clips into the ti
- Click Render button ->AVI DV
Step 3: Get the converter programme called vcdimager
$ sudo apt-get install vcdimager
ffmpeg -i inputfile.avi -target pal-vcd outfilename.mpg
# create the cue and bin files. The label did not allow for spaces.
vcdimager -t vcd2 -l"Martha-Swimming-May-2010" -c vcd2.cue -b vcd2.bin outfilename.mpg
Step 5: Using K3B, choose project for Burn Image
Insert a blank CDROM
Image to burn ->Select the .cue file.
K3B version 1.68.0

Here is a guide to get started with QT programming (qt4 in this case) on Kubuntu 9.10. You will need the demo and the Graphical development tool
A. Setting up the environment
Step 1: Install the libraries and compilers. This include libraries such as "QLabel" and QLayout from the QtGui
$ sudo apt-get install build-essential kdelibs4-dev libqt4-qt3support libqt4-assistant
Step 2: Install the demos
$ sudo apt-get install qt4-demos
Step 3: Configure Linux to compile with qt4 instead of the default qt3
$ sudo update-alternatives --config qmake
Step 4: # install the Graphical development tool
$ sudo apt-get install kdevelop
Step 5: Read info on QT4 through the manuals at /usr/share/qt4/doc/html/index.html
B. General programming setup of project, compiling and execute
Step 1: Create the source files. E.g. .cpp, .h, etc.
Just copy from the demo files in /usr/lib/qt4/examples. I will use files from the example tabdialogs.
$ cp -r /usr/lib/qt4/examples/dialogs/tabdialog/ ~
$ cd ~/tabdialog
Step 2: Create the project file. The project file (.pro) define headers, sources, form and other files which the application consists of.
$ qmake -project
Step 3: Compile
Step 4: Run the programmes.
Alternatively, use the KDevelop to manage the project. Start KDevelop and open to .pro file.

too many programmes running, lower processing speed of hardware, insufficient resources, etc.
You can use basic linux tools to give readings on the hard disk for benchmark purpose. Here are among commands that anyone can use via a terminal;
- Get timing of cache and device reads on inactive systems. This means nothing else is running during the test.
hdparm -tT /dev/sda
- Shows the files opened by processes.
- Monitor balance between input/output load of physical disk using the sysstat package. iostat -x
- Space on mounted devices.
- Monitor load on a Linux system, default every 10 second updated.
Details on how to use the above commands can be found in the respective man pages.
Now you can tell someone, my disk is faster than yours.

The MF110 features
Network: HSUPA/HSDPA/UMTS 2100 MHz,EDGE/GPRS/GSM 850/900/1800/1900MHz
Data transmission speeds: 7.2Mbps DL 5.76Mbps UL
Weight: 21.5 gramme
Application: Join Air with SMS service, Data service, Applications management, Data concurrent. This allowed me to add other service providers (yet to be tested) with the same modem.
Installation on Linux KUbuntu 9.10
- Install wvdial from KPackageKit
- Plug the MF110 into the USB slot. Mount the MF110 and enter the directory "Linux"
- Extract "PCL_ZTEDCV.tar.gz" to your HOME directory.
- Open a terminal and type "sudo ./install.sh"
- Launch the application "Join Air" from the KMenu
- In Join Air, at the Internet menu (A globe icon), click "Connect". Minimise this window but do not close as its needed to maintain Internet connection.
- It connects directly with initial IP 121.121.X.X and tries to open the web page mylaunchpad.com.my
Dial number: *99#
APN: static: maxisbb
Connection has been pretty much inconsistent. Its fast at times, then no connection, then have to keep reloading the page. I like its thumbdrive size and the blinking lights. The Join Air application is also easy to read and use.

Just maybe, that missing USB drive containing your phone number will come back to you if found.
Here is how to name the disk on Kubuntu 9.10 or other similar Linux like CentOS.
Insert the USB disk and determine the device and partition. E.g. /dev/sdb1
Easily done with the mount command.
Unmount the disk (Do not unplug from the USB).
sudo umount /dev/sdb1
Check existing disk name
sudo mlabel -i /dev/sdb1 -s ::
Rename the disk label. E.g. below, replace the word "myphonenumber" with anything you like with a limit of 12 characters.
sudo mlabel -i /dev/sdb1 -s ::myphonenumber
Remove the USB disk, and reinsert back to confirm the name has changed.
For more details see ubuntu.com

Since my upgrade to OpenOffice.org 3.1.1, I have not explored Calc much. When I tried to print a spreadsheet that ran across 40 pages. I tried to have the first 2 rows repeat as headers in every page, an error appeared "Invalid Sheet Range".
- Open the Calc spreahsheet.
- In the menu choose Tools ->Option ->OpenOffice.org Calc ->Formula
- In Formula Syntax, it shows "Calc A1". Click on the dropdown box and choose "Calc A1".
- Click "Ok".
Some trigger must have failed to detect the values as "Calc A1". Thank you Arnel for giving the solution in Oct 2009.

Sun is not only about hardware. What will happen to OpenOffice.org, Java and MySQL? How about the Sun and MySQL Certifications?
How will Jonathan, being the last Sun Microsystem's CEO end his career there?
All the debates are ongoing in the internet but I look forward to Oracle making clear statements on these concerns.

Kubuntu is installed on a Pentium III with 200Mb RAM having 20Gb hard disk. Mouse is with the Nano wireless and keyboard is PS2. With the L2 cache being 512k, it should mean something to Kubuntu to run smoothly (almost). Working just ok, and the desktop looks neat. Swap is taking up 144Mb of the 1,400Mb allocated during installation.
Following are among the first thing I did after install;
1. Did a system update and removed the package kubuntu-firefox-installer.
2. Set the screen to resolution to 1024x768
3. Checked with Konqueror the Internet connection...connected to the broadband via router.
3. Used KPackagerKit to install Firefox 3.5
4. Added stuff like password gorilla, Kphotoalbum
List of things to do next:
1. Install Java and Flash
2. Get a PDF reader. Currently Okular is installed by default.
