howto: Speed up your Linux up to 10x

You’ve probably heard about the 200 lines kernel patch that makes wonders ? Well there’s an easier way to dramatically increase your Linux Distro reactiveness and obtain a similar result, I tested it and it’s really working , this is for Ubuntu:

How to do a Chrome/Opera specific stylesheet

You’ve probably wondered how to load specific CSS stylesheets for Chrome, Safari and Opera, some kind of <!–[if Chrome]> CSS conditional comment. Unfortunately these conditional comments work only with the IE Series.

There’s an easy PHP solution to recreate this behaviour for other browsers, the excellent browser detecting script remade by Chris Schuld, this script will let you use this kind of code in your XHTML views:

<?php $browser = $browser->getBrowser();?>

<?php if($browser == Browser::BROWSER_CHROME || $browser == Browser::BROWSER_SAFARI):?>

<link href=”css/chrome-safari.css” type=”text/css” rel=”stylesheet” />

<?php endif;?>

In this example I deliberately took Chrome/Safari: Using a very similar version of Webkit HTML Engine, both render quite closely web pages, so you can use the same CSS file for both of them.

There’s an exhaustive list of supported browsers, even the iPhone Safari version and Lynx are handled by the script.

Howto: Ctrl+Alt+Del open System Monitor in GNOME

If you want to open the System Monitor in Gnome just like Windows, here’s what you have to do :



1) Disable the current Ctrl+Alt+Del combination (Logout) :

In Ubuntu Go to System ->Preferences ->Keyboard Shortcuts -> Desktop disable logout shortcut (hit backspace) if it’s associated with Ctrl+Alt+Del.

2) Enter these commands in a shell :

 

gconftool-2 -t str --set /apps/metacity/global_keybindings/run_command_1 "Delete"

 

gconftool-2 -t str --set /apps/metacity/keybinding_commands/command_1 "gnome-system-monitor"

 

Note that these are Metacity global keybindings, normally you should have the 12 run commands disabled so you can use 1 to 12 numbers range in run_command_x and command_x, it’s always better to check their current status, hit Alt+F2 enter gconf-editor then open apps -> metacity -> global_keybindings.

I got this informations reading this excellent post. Take also a look at Ubuntu Guide.

Use Internet Explorer without Windows nor Emulation

Wonder how ? If you want to render a page or a website in all IE versions starting from 5.5, just try :

 

 

A Firefox extension can be found here.

To add the service to your website paste this code on the body :

<form method="post" id="form" name="form" action="http://ipinfo.info/netrenderer/index.php"
accept-charset="utf-8" target="_blank">

<select name="browser" style="width: 145px;">

<option value="ie8">Internet Explorer 8</option>

<option value="ie7">Internet Explorer 7</option>

<option value="ie6" selected="selected">Internet Explorer 6</option>

<option value="ie55">Internet Explorer 5.5</option>

<option value="ie-mix">IE7-IE6 Mixed</option>

<option value="ie-diff">IE7-IE6 Difference</option></select>&nbsp;

<input name="url" id="url" value="http://" size="61" maxlength="240" type="text">

<input name="go" value="Render" type="submit">

</form>

Another extension for all browsers rendering is available here but it’s still experimental and needs a trial registration to BrowserCam Capture Service.

 

 

You can also test your page in 23 browsers with litmus but you’ll have to pay (Only IE7 and FF2 rendering are free)
