Can I Burn A Dvd More Than Once

Ubuntu RSS readers



RSS
According to Wikipedia is " RSS is a family of web feed formats

encoded in XML

.
be used to disseminate information


frequently updated to users who have signed to the source of content. "

In other words, because RSS can keep up to date with changes in websites (whatever they are) that we read regularly, being informed of any updates to them through our RSS reader program. In this way, is the information that travels to us instead of having to be reviewed one by one our websites interest. This system is particularly useful for tracking blogs, discussion forums, personal profiles, or any page of dynamic content in general.

RSS reader programs will inform us of these changes in a similar way as you would an email client. Let's see now four different options for RSS reading in Ubuntu.


Google Reader This is a free service from Google

, we will not need to install any extra software (using our favorite browser) to add RSS feeds, listing the latest news and link to their respective websites .
    Its operation is very simple, you just have to use the subscription button Add
  • , provide the address of the subscription and you will see a summary of news from the web added.

RSS reader Google Reader

can add as many subscriptions as you want (eg this blog:
http://dmolinap.blogspot.com/rss.xml
).
Note: These addresses normally find on every page and will be accompanied by the RSS icon (like the beginning of this article.)

This is the reader recommended for users who already have other services like Google and manage everything via the browser.

Liferea (Linux Feed Reader)

    This is undoubtedly the most complete of the four readers considered in this paper, has an interface similar to e-mail readers, very simple to use and very clear, provides a large number of subscriptions predefined theme "Linuxero" and add a new subscription is as easy as pressing the "+" and give the URL for the RSS (eg this blog:
  • http://dmolinap.blogspot. com / rss.xml ). We will install
easily from the Software Center Ubuntu
or with the command: sudo aptitude install
liferea




Liferea


can be minimized in the Gnome notification area and reports of developments in time real through the notification system so you do not have to be aware of the program or keep it open to be promptly informed. Liferea RSS reader is recommended for those who read a lot of subscriptions daily. FeedReader screenlet A practical and original reading is using the gadgets RSS Screenlets desktop. To install (if you have not yet) used the command: sudo aptitude install & & screenlets screenlets

seek the FeedReader and activate it, go to their properties and give the direction we want to continue (eg this blog:
http://dmolinap.blogspot.com/rss.xml
).

FeedReader screenlet
Its operation is very simple, when you mouse over a headline we expand the news and if we click open the story in the browser. The main limitation of this system is that we can only follow a web for each FeedReader we have on display. Other Screenlets

able to read RSS and gadgets in other systems (
Adobe Air
,
Google Gadgets
    , KDE Plasmoids
  • ...) The reader is recommended for those users who read a few RSS feeds and estéctica concerned about maintaining their desks.
Newsbeuter
As always reserve a space for lovers of the console. Newsbeuter RSS Reader is a text mode, with lots of options and features, able to get the latest news, articles and even show the link to Google Reader or services lynx browser (in text mode of course) Installed with the command: sudo aptitude install

newsbeuter
  • We add at least one subscription to start the file ~ / .newsbeuter / urls (eg this blog: http: / / dmolinap.blogspot.com / rss.xml ) and we can launch the program with the command:-r newsbeuter

text mode This reader RSS is recommended for those who do not have a GUI or prefer to use the console. More RSS

Good Street Bmx Places

optimizes the viewing area in the NetBook



Increasingly, users of these small but powerful devices and more and more people use them with Ubuntu . One of its strengths is its small size, but this in turn is its greatest disadvantage, with screens of between 9 and 11 "and resolutions from 800x600 to 1024x600, every inch of screen that can win will be welcome.

In this article we will see a series tricks and options designed to take full advantage of these small screens and minimize the area occupied by the system. Some of these tips apply to your NetBook, some not, that everyone wants and can decide which to use and which no. I hope that you may find helpful.
  • Adjust settings for Gnome
Reduce the size of system fonts of 10 points by default to 8 points:

gconftool-2 - set / apps / nautilus / preferences / desktop_font - type string "Sans 8"
gconftool-2 - set / desktop / gnome / interface / document_font_name - type string "Sans 8 "


gconftool-2 - set / desktop / gnome / interface / font_name - type string" Sans 8 "
gconftool-2 - set / apps / metacity / general / titlebar_font - type string" Sans Bold 8 " gconftool-2 - set / desktop / gnome / interface / monospace_font_name - type string" Monospace 8 "


Reduce the size of the panels to 18 points:
  • gconftool-2 - set / apps/panel/toplevels/top_panel_screen0/size - Type integer 18
gconftool-2 - set / apps/panel/toplevels/bottom_panel_screen0/size - type integer 18

Applets that increase the viewing area
Numerous panel applet Gnome designed to maximize the screen of any device, let's see how to take advantage of some of them.

Gnome main menu much space on the panel but can switch to another applet much more compact and offers the same functionality. Eliminates
Menu Bar applet and add the applet Main Menu



applets space occupied by the Menu Bar and Main Menu respectively The Global applet
menu displays the menu bar of each application in the Gnome panel, saving the space occupied by the bar for each application. Furthermore, this applet serves as a window and changing list of applications, saving even more space on the panel. To install this applet uses the command: sudo aptitude install
gnome-applet-globalmenu
Global


menu applet Applets

Window displays the title bar and control buttons the window into the Gnome panel, saving the space occupied by the bar for each application. You have the packages for Ubuntu and instructions for use in Applets Window GNOME-Look.org


Applets Window

Running full-screen programs

Some programs have on their menus the option of running full screen saving the space for the panel, the title bar of the window and the docks. To enable this feature in all applications and assign the key combination Alt + F11:
If your window manager is Metacity with Order:
gconftool-2 - set / apps / metacity / window_keybindings / toggle_fullscreen - type string "Alt F11"
  • If your window manager is Compiz from menu:
System - Preferences - CompizConfig Options Manager - Shares of extra window manager - Enable or disable Full Screen - Alt-F11


Kwin
fullscreen

connect a larger monitor
A good way to save some vision is to connect an external monitor, any old 14 "tengais out there will do, but obviously as more is better. In my case I have connected a 19 "monitor that allows a resolution of 1440x900 pixels. From the menu System - Preferences - Screen can choose the resolution of each monitor separately, the relative position of the 2 monitors if we use them both and which is turned on and off at all times.



  • System - Preferences - Screen

In this way we can get differnt provisions: that the image displayed by a single monitor, which displays the same in the two monitors or merge the two screens on a single desktop .

Desktop compound: up netbook screen, below the external display



Docks
Although the use of docks is not recommended for small screens there are some users who do not want waive these useful gadgets. If you are going to use a dock trying to follow these recommendations: Keep up the dock
small
Make use auto-hide options

  • The dock Gnome-do to size 24 and intelligent concealment

How To Get Rid Of Lupus Naturally

Compiz + Nouveau in Beta2

Now that we are all aware of the output of Ubuntu Beta2 we Lucid Lynx to see how we use one of its main novelties, free driver for nVidia graphics,
nouveau, with compiz

. By default the nouveau driver offers Composite extension , responsible for a large number of cosmetic improvements (slides, round windows, docks ...) but allows activation of compiz. Let's see now step by step how to enable this support.

Note: This article has been made possible through the collaboration of the users on the channel # ubuntu +1 for the IRC-Hispano (irc.irc-hispano.org).
identify our graphics

    For the exact model of our graphics will use the command:
  • lspci Open the application
System - Administration - Software Sources and in the tab

Another
add software repositories Edgers Xorg, which are: deb http://ppa.launchpad.net/xorg-edgers/ubuntu lucid main deb-src
http://ppa.launchpad.net/xorg-edgers/ubuntu main lucid

closed the application and reload the repositories to update the database. Now install the necessary software with the command: sudo aptitude
update & & sudo aptitude dist-upgrade & & sudo aptitude install firmware nouveau-
After loading the gui see that 3D hardware support is active with the command:
glxinfo 0.4 GL_NV_blend_square on NV84, GL_NV_conditional_render, GL_NV_light_max_exponent,

If you do not have 3D acceleration will see something like this: direct rendering: Yes OpenGL renderer string : Software Rasterizer

    Start compiz
  • If you have 3D hardware acceleration and we can move to start compiz with the command:
compiz - replace &

and check it out activating any of the compiz plugins. For example I have activated the cube:

Plugin desktop cube using compiz + nouveau
If we stop compiz active work for all sessions since the implementation System - Preferences - Appearance
in Visual Effects tab and checking
Extra or Custom

If we set the behavior of the application will use effects
System - Preferences - Options Manager CompizConfig
    :


You have many indications on the compiz settings in the series Compiz-depth articles

  • Performance Tests Although there is no standard way to analyze the performance of 3D've done a series of comparisons on the same hardware using Karmic + nvidia driver and owner of Lucid + nouveau, I leave the results in a table to judge for yourselves.

Compiz Benchmark

From the results we can say that desktop effects nouveau behaves more or less like the nvidia proprietary driver, but on the subject of OpenGL games is still far from matching its performance.

Lucid Lynx Emulators: MAME



MAME (Multi Arcade Machine Emulator) is an emulator of several arcade and console games that allow us play lots of games (over 8,000 in the latest version) and recall the days of Pac-Man, Space Invaders, Street Fighter II and many others.
program
There are many versions of this program with different options and enhancements, versions for GNU / Linux are generically called XMAME and Ubuntu repositories have the most common:
xmame-x: MAME basic graphics mode xmame-sdl: MAME with several graphic and sound enhancements, do not need or support 3D accelerated driver (recommended) xmame-gl: MAME with support 3D accelerated driver needed.
xmame-svga: MAME for text mode
just choose the one that best fits your system and instalais with the package manager. For example to install xmame-sdl (recommended) use the command: sudo aptitude install
xmame-sdl

  • The ROMS
A ROM is the original game turned into a manageable file for MAME and easy online distribution. Most of the ROMS are not free so I can not tell you of place here. But there are many sites where you can download as

Rom-World. Note: Not all ROMS are playable to find some as incomplete, others that are ready for other emulators, others are not yet supported by MAME ... so I recommend that you succeed a number of them before. / usr / games ) Gmameui showing the options panel and preview the game : Designed to integrate into the KDE has the same options as above with laventaja that is in the official repositories so to install simply run: sudo aptitude install
ROMS Once downloaded and installed the necessary start the game with the command-rompath

xmame.SDL "directory where you saved the roms" "name game"

Metal Slug 3 on xmame-sdl

graphical interface to manage the large amount of ROMS available XMAME options and implementation of the games there are various graphical interfaces that will facilitate the management of the program. Most importantly

to use these programs is to tell which is the directory where we store the ROMS and what is the executable program XMAME we installed (you can find this executable in the directory

Gmameui

: Designed to integrate into the GNOME desktop this simple program provides all the necessary options to use XMAME, list of games, preview, catch, managing general options or game ...
