FireFox Tweak

I came across this simple FireFox hack that makes webpages download @ least 5x faster ; ok maybe 2x. This will work on Linux , Mac , Windows….

Follow these simple instructions,

Speed up page rendering
By default, Firefox doesn’t try to render a web page for 250 milliseconds while it’s waiting for data. If you use about:config to add the Integer preference nglayout.initialpaint.delay, and set the value to 0, Firefox immediately starts to display the page, even without complete data. The drawback, especially on slower machines, is that the total time to display the page will be longer.
Enable Pipelining
Pipelining is an experimental feature, designed to improve page-load performance, that is unfortunately not well supported by some web servers and proxies. To try it out, by using about:config to set the following preferences:

network.http.pipelining
Set this to true, to enable pipelining.
network.http.proxy.pipelining
Set this to true, to enable pipelining to the proxy server.
network.http.pipelining.maxrequests
Set this to 8, to have a maximum of 8 pipelining requests at once. Possible values are from 1 to 8.

For more information about pipelining, read the HTTP/1.1 Pipelining FAQ.

Specify where to store the cache
To specify in which folder the cache is stored, use about:config to add the String preference browser.cache.disk.parent_directory, and set the value to C:\Path To Cache.Replace Path To Cache with the actual path to your cache folder.
Specify the memory cache usage
Normally, Firefox determines the memory cache usage dynamically based on the amount of available memory. To specify a specific amount of memory cache, use about:config to add the Intefer preference browser.cache.memory.capacity, and set the value:

-1
(default) Determine the amount of memory cache dynamically.
0
None.
n
Memory capacity in kilobytes. For example: 4096.

To disable the memory cache completely, use about:config to set the preference browser.cache.memory.enable to false.

Kiosk Browser
Andrew Mutch has written a comprehensive tutorial that explains how to modify Firefox to run in a kiosk-style mode. Read all about this here.
Limit Firefox to specific web addresses
Many libraries are now providing web-based online catalogs and access to online databases. Often, libraries don’t want computers provided for those uses to have access to the entire Internet. This method will assist you in limiting Firefox access to a pre-defined number of sites.Restricting web access is accomplished by using the proxy settings in Firefox. Read all about how to accomplish this on this page, written by Andrew Mutch.

–>

View page source using an external program
If you want to view the HTML source of a web page using an external text editor instead of the built-in source viewer in Firefox, use about:config to set view_source.editor.external to true, and then set view_source.editor.path to e.g. C:\Windows\Notepad.exe or whatever is your preferred text editor.

Linux Commercial

I am working on a series of beach maps . Click here to view the entire project.

This map was made with QGIS Titan on Ubuntu Linux.

Keep Checking over @ MoreBeach for more Qgis samples.

GRRRR…
unable to lookup (none) via gethostbyname()

Not sure how I managed to delete localhost on my laptop but here is a quick fix to get your administrative applications back up and runing. I was getting this error in the terminal ; unable to lookup (none) via gethostbyname() , This cripled a few of my programs running under wine and access to my wifi card etc…

Reboot Ubuntu, hit escape when loading GRUB , select recovery mode ( this will log into root) , then type the following : nano /etc/hosts .. add the line below following in the editor .

127.0.0.1 localhost your-computer-name-here

If you need to uncompress a .rar archive in Linux, you can download a program called unrar. If you are using Ubuntu or Debian, you can install unrar by opening a terminal and typing sudo apt-get install unrar. Then read the instructions by typing man unrar.

Basically, to unrar a file in Linux, just navigate to the directory where your rar archive is and type unrar x [filename.rar], replacing [filename.rar] with the name of your rar archive.

Also check out the great page over at cyberciti.biz on how to install and use rar files on Linux.

Overview

Joomla! takes a fairly unique approach to several areas of web content management. Before we move on to more detailed instructions on how to use Joomla! to manage your web site, we wanted to take a few moments to provide a brief explanation of each of these areas.

Browser-based Administration

Almost every function and setting in Joomla! can be controlled directly through your web browser, from both the public part of the web site, which we call the Site (Front-end) and from the behind-the-scenes part of your site which requires permission to access, which we call the Administrator (Back-end). All administration functions are available in the Administrator to those Users who have been given management privileges. Content may also be edited directly on the Site, where some of the Administrator functions are available to logged-in Users who have been granted editing privileges.

Parameters

In Joomla!, parameters are configuration settings that are available in most control panels. Parameter settings allow you to modify script variables from the Administrator (Back-end), without the need to open and manually edit, or even understand, PHP scripts or configuration files.

Each type, Content (Sections, Categories, and Articles), Modules, and Menu Items all have parameter sections. Components and Plugins may also have parameters. Which of these types they are determines which variables can be set in the Parameters area. For example, for a Content Article the parameters allow you to Show or Hide the e-mail, print, and PDF icons, Article title, assign an alternate template for that Article, and control many other variables. Components may have parameters to change settings that normally would involve modifying the actual PHP code.

Flexible Content Organization

Joomla! handles content organization and menu creation in two separate stages. This may at first seem unusual if you are used to having the content structure determine what appears in menus. However, separating the two is a logical, straightforward approach that gives you infinite control over how links are presented on each individual page of your Joomla! site.

Section/Category/Article

Content in Joomla! is organized in a Section-Category-Article model. Sections contain Categories, Categories contain Articles. The controls are found in your Content Manager. It is useful to think of this framework as a way to internally organize content, independently of how it is presented on the site. Using the Menu system, you can create navigational menus that link to any combination of Sections, Categories, and Articles.

Other containers for content include Static Pages and User Modules, where you can enter text directly. These are usually used to complement the content stored in the main Section-Category-Article set-up.

Menus

Creating navigational menus for your Joomla! site provides you with a powerful and flexible method to help your visitors move around with simplicity. You can think of Menus as blocks of links to content, with each link independently configured, and each Menu block positionable anywhere in your Site (Front-end) layout.

Menu Items can link to Sections, Categories, Articles, Components, Static Pages and external sites. The Menu Manager allows you to create any number of individual Menus, which appear as individual Modules. Menu links can also be nested indefinitely. Each link has associated Parameters, which allow you to control how the destination content is presented. Individual Menu Modules can appear anywhere in a Template, based on Module Positions.

One-page Templates

Templates in Joomla! are contained in a single file. This is quite different from many web applications, where template components are spread across many different files. Joomla! templates work in basically the same way as a single HTML page, which greatly simplifies the job for the graphic designer. Dynamic content is inserted via PHP tags anywhere you would like it to appear in the page layout.

Module Positions

Module Positions allow you to place dynamic content anywhere in your template. The position code is a single line of PHP, where “position” is replaced by the position name:

<?php mosLoadModules ( 'position' ); ?>

The code is placed in the template file. You can use the many prenamed positions, or create others as your requirements dictate. At each position, any number of Modules can be displayed in an assigned order. For example, you can place the position identified as “left” in the left column of a Template, assign the Main Menu, Search and Login Form Modules to the “left” Module Position (in Menu Manger), and those Modules will appear in the left column, in the assigned order.

To view Module Positions, go to Site->Preview->Inline with Position. This displays your current Template, superimposed with the name and location of each Module Position.

Powerful Extensions: Components, Modules, and Plugins

Extending and customizing Joomla! is easily accomplished with a range of Extensions options. Joomla! has three types of Extensions called Components, Modules, and Plugins. You can install, configure, and uninstall these elements through the Administrator (Back-end) control panel.

Components are essentially new applications. Seven default Components are part of the standard Joomla! installation. They provide functionality such as polls, content syndication (newsfeeds), and mass email to registered users. There are hundreds of additional, third-party components which can add many powerful capabilities such as e-commerce, photo galleries, forums, and more. Feel free to browse and download extensions by clicking on the Extensions tab at the top of this page (which will take you to extensions.joomla.org).
Modules can contain different types of content, and may be installed, or created within Joomla!. Third-party Modules can contain small applications (for example: to display weather conditions or generate random quotes or images). Third-party Modules are often used to display the output from a Component. Joomla! includes a number of default Modules, some affecting Site (Front-end) content, and others used in the Administrator (Back-end). User modules are created within the Administrator, and may utilize formatted text, unformatted text, and/or newsfeeds.

Plugins generally enable or enhance Joomla! features. For example, a variety of WYSIWYG editors are installed as Plugins. Other Plugins connect Joomla! with external resources, like a third-party library.

Linux on PS3

Linux for PlayStation 3

The PlayStation 3 is capable to run Linux operating systems installed on the console hard disk. Yellow Dog Linux offer an official distro for the console [1], but other distros like Fedora Core, Gentoo and Ubuntu Linux are also compatible.


History

Sony is approaching with Linux since 2000s in PlayStation 2 marketing when they promoted and officialy released the PS2 Linux Kit sold in a package with keyboard, mouse hard disk and modem.

Originally Sony stated that they were going to pre-install Linux on the PS3‘s hard drive, but current units shipping do not include Linux pre-installed. Instead, Sony has made an option in the XMB menu to install other operating systems.[2]

Soon after the PS3 launch, Sony released an “OtherOS” application that allowed booting into Linux and an Addon CD image that modded the selected distribution’s kernel to properly run on the PS3.

Distros

Ubuntu, Fedora Core 5, Gentoo and Debian have been run on the PS3;[3][4][5][6] Fedora Core 6 has also been managed to run on the PS3 although it requires many more steps to get it properly working. The Sony-sponsored Yellow Dog Linux for the PS3 was released on November 27, 2006 to the YDL.net community, and was released on DVD on December 11, 2006, and finally as a publicly available image in late December.[7]
