7 Lightweight Linux Browsers You may want to Consider for Fast Browsing Experience

Mozilla Firefox may becoming the most popular browser in Linux world but these are also some competitors such as Opera, Konqueror, Google Chrome, Epiphany and others. The above browser has similar function and quite nice to be used on a standard PC. Unfortunately, as a modern and complex  application, all listed browser need  a fast, modern computer with standard modern hardware, such as minimum 256 MB of RAM. If you trying to run one of these on the older hardware, the result may vary but most of them will running slow, even on 256 MB of RAM. Google Chrome may run faster than Mozilla Firefox but overall working with modern browser on an older PC  is very inconvenient.

The older hardware usually used for a few application or dedicated for one or two service which do not need much resources. Browser may be needed for managing web administration. Supporting all the Web standards may not required, rendering most pages correctly, much faster and require less system resources are the most important key points. Such programs usually don’t serve CSS, JavaScript, or more complicated HTML elements.

Actually, older hardware  isn’t the only factor to use lightweight browsers. People may choose to use lightweight browser even on modern hardware, only to get high performance and faster browser experience. GUI or text mode environment, operating system configuration and personal preferences are others factor why lightweight browsers has a unique position in modern computing.

Below are some lightweight Linux browsers for Linux you should consider for fast browsing experience :

1. Midori

How to Add PHP & Javascript Code to Smarty Template (Serendipity, Pligg)

I manages various website and some of them are running on Serendipity blog engine or a Digg-looks-alike, Pligg. Both engine use Smarty framework based on PHP code. Although Smarty built from PHP engine, it has different style in code writing than another CMS based on PHP like WordPress. Smarty using their own tags that will be parsed on their engine, so adding Javascript or PHP code can not be directly written in the related tpl file (an extension for Smarty template).

If you wish to add a Javascript code like Google Adsense or a PHP code into Smarty template, use the following tips :

  1. Open your related tpl file and use {php} and {/php} tags to include the PHP file 
    {php}include('/home//vavai/vavai.net/myphpfile.php');{/php}

    Please note that I would prefer to use absolute path and not the relative path instead.

  2. Open your related tpl file and use the {literal} and {/literal} tags to add the Javascript code. Place your Javascript code inside literal tags as shown on the following example : 
    {literal}<script type="text/javascript">// <![CDATA[
initializetabcontent("tags_comments")
// ]]></script>{/literal}

On the sample #1, I would prefer to include the php file rather than write the PHP code directly on Smarty file. It will make a code a lot easier to manage, clean, easy to understand and we have a flexible way to add or remove the related file.
