Try Lib-Ray: “Sintel” Lib-Ray PROTOTYPE v0.2

The following text comes from: http://www.archive.org/details/sintelLib-rayPrototypeV0.2:

‘The Sintel PROTOTYPE of the Lib-Ray free/open fixed media format for high-definition video without DRM or other “anti-features”. Since it is a prototype, it comes with no guarantees about stability or compatibility, but it is best viewed using Google’s Chromium web browser in full-screen mode on a system with a 1920×1080 “full HD” screen. Some features do not yet work even on this configuration, however, as they require elements of HTML5 that are not yet implemented. Because it’s a short movie, the ISO is relatively small (2.1 GB), and it will fit easily onto an inexpensive single-layer DVD-R disk”.

More details about the project are also available from the Lib-Ray site: http://lib-ray.orgAddThis

Another way to share files between Ubuntu and Windows

This tutorial will show you another way to share and to access the network share folders between Windows and Ubuntu machines. When file sharing is enabled, both systems can access files and folders on any of the PCs. Users with accounts on Ubuntu systems will also be able to access the content directly from your home.

1. To begin, you will need to log on to your Windows operating system. Click ‘Start’ -> search for ‘Network and Sharing Center’ and click on it.

2. Access the ‘Change advanced settings sharing. ” option.

3. Enable file sharing and backup as well.

4. At this point, you need to switch your operating system to Ubuntu. Once you log in, click on ‘Ubuntu menu -> System Tools “

5. Then select ‘Ubuntu Software Center. “

6. Find and install ‘Samba‘. This software is required for a better compatibility between the two operating systems.

7. After Samba is installed, you should go to ‘System → Administration –> Samba’.

8. Then click ‘Preferences -> Server Settings’.

9. Write the name of the workgroup you set for your Windows PC(s). If you do not know the exact name because you did not set it, the default name for Windows Workgroups is set to ‘WORKGROUP‘ (capitalizing is not required, however, since Windows is generally not case-sensitive). AddThis

How to correctly configure and use the Windows Network on Ubuntu 10.04 LTS

At the beginning it appeared as a no-solved mystery because in all the many posts I read, there were no effective solutions. On my Ubuntu 10.04 LTS I was no able to use the external hard disk I had connected to the LAN and every time I tried to mount it I only received this message: Unable to mount location – Failed to retrieve share list from server


In few words it was not possible to use the Windows Network and all the people with the same problem (which is specific for the Ubuntu 10.04) suggested to reconfigure Samba but all the configuration and scripts I tried were no effective to let me use the external hard disk.

At the end I found someone who talked about a possible firewall misconfiguration and I tried in many ways to bypass the situation using ufw commands and opening ports and services over the LAN:

$ sudo ufw status
[sudo] password for *****:
Status: active

To                                      Action            From
—                                        ——                —-
135,139,445/tcp           ALLOW       Anywhere (log)
137,138/udp                  ALLOW       Anywhere (log)
Samba                             ALLOW       Anywhere
192.168.0.3 Samba     ALLOW       10.0.0.0/8
10.0.0.0/8                    ALLOW       192.168.0.3 Samba

Unfortunately, every new permission I granted to Samba on my Firewall was not a real solution but when I tried to stop the Firewall (System –> Administration –> Firewall Configuration) using the default firewall manager, Ubuntu was able to find and work on the external hard disk.

For this reason I made some tests and found this solution:

1 – enter your router settings and find the list of the attached device

2 – find the name and the MAC address of the LAN device you want to connect to your PC

3 – find the menu for the Lan Setup and add an Address Reservation for the above device. Now you are sure that the router will always assign the same address to the device

4 – back to Ubuntu, install and launch Firestarter (for some incomprehensible reasons the default firewall manager is not able to create rules for Samba services and ports)

5 – on Firestarter, go to Preferences —> Policy Editor and click on “Apply policy changes immediately”

6 – try to connect again to Windows Network, obviously (sic) it will not work but then go to Firestarter —> Events and you will notice that the last line is the “missing” external disk which has an “unknown” service

7 – right-click the mouse on this line and “Allow connections from source”. Now the external hard disk is visible from Ubuntu 10.04 LTS and it is possible to work on it!

8 – to be sure that your LAN device will be rightly connected to Ubuntu 10.04 every time you boot up it: go to System –> Preferences –> Startup Applications

9 – add a new Firestarter rule typing the following command: sudo firestarter

That’s all! I hope you can find this post useful! AddThis

How to uninstall OpenOffice and install LibreOffice on Ubuntu 10.04 LTS

At the end I decided! I want to uninstall OpenOffice on my Ubuntu 10.04 LTS and substitute it with an always updated LibreOffice. After some researches on the web I decide to develop my own procedure to be sure that LibreOffice will be always updated with the last available edition.

First of all it is necessary to remove OpenOffice:

- go to System –> Administration –> Synaptic Package Manager –> Quick Search and type OpenOffice

- Mark for Complete Removal all the installed OpenOffice software and Apply  your choice, then exit the program

Now, open Terminal and add the PPA repository:

sudo add-apt-repository ppa:libreoffice/ppa

Update the system:

sudo apt-get update Last but not least, go back to Synaptic Package Manager –> Quick Search and type LibreOffice

Select the LibreOffice software and all the add-ons you prefer then Apply  your choice.

That’s all! You have the last version of LibreOffice installed on your Ubuntu 10.04 LTS and you are also sure that Synaptic will update the packages when a new version is available! AddThis
