Online analysis of a webpage’s loading time

View original post

Have you ever wondered how much time it takes a browser to load your web page across the internet or how this total webpage load time is distributed among the various HTTP requests that are sent to the web server in order to retrieve all the objects, including images, javascript, flash animations, et cetera your page contains? Recently, I’ve been wondering about such things, so I started searching for services that can provide both an estimation of a web page’s loading time and also some analysis about how long the retrieval of each of its objects lasts. The one that caught my attention is Pingdom’s Full Page Test. The service can be used free of charge. I guess the visual representation of the web page loading time and all the available features are quite satisfactory for a free service.

Size text with “em” in your CSS - Explained with example

View original post

Sizing text for the screen using ems in your Cascading Style Sheet (CSS) can be a problem, if you are not a web designer and have never spent any time reading about the differences between the various units that can be used to measure text size, especially pixels (px) and ems (em) which are the most frequently used. I am sure there are a lot of guides out there that explain the issues that arise by using either one of the aforementioned units, but I consider the article How to size text using ems a very good place to start, if ems is what you aim for.

It seems that the main advantage of using ems instead of pixels is that text size can be translated correctly by all major browsers when the user resizes the text from within the browser, overriding the text size defined in the CSS. I feel that, once again, people are forced to waste their valuable time because of Microsoft’s old-fashioned methods of protecting its investment by not following the established standards, so… well, taking into account that Internet Explorer (IE) is still a very popular web browser, I guess that noone can actually avoid reading about the pros and cons of using ems or pixels to size text for the web.

Sopcast with GUI and sop:// URLs in Ubuntu

View original post

This guide will help you install sopcast on Ubuntu 7.10 Gutsy. It will also help you get a special modified version of the GUI running and setup firefox to send sop:// links to the program.

Installing packages

Make sure you have all universe and multiverse repositories switched on. Then, in terminal:

sudo apt-get install qt3-apps-dev vlc build-essential

Downloading the latest SopCast binary

Link: Sopcast ix86 binary

Unzip it and cd into that directory using terminal. Then run:

sudo cp sp-sc-auth /usr/bin/sp-sc

Downloading and building the latest GUI

Download this specially modified source package. I have added URL handling.

Link: RKMOD version of QSopCast

Aga*in, unzip it and cd into that (src) directory using terminal. Then run

sudo qmakesudo makesudo make install

This should compile the source and install the binary into the correct location.

Creating a menu shortcut

Go to System / Preferences / Main Menu… then ‘Internet’ and ‘Add New Item’. Give it the name “QSopCast” and command “qsopcast”. You should now be able to launch from the main menu.

Setting up the GUI

Once the gui is open, goto config then config again. Make sure that the player settings are all set to “vlc” and that the channel URL is set to “http://www.sopcast.com/gchlxml“

You should now be able to watch sop casts by selecting a channel, launching it and then hitting player when the stream is at 100%

Firefox sop:// URLS

Go into firefox and enter URL: “about:config”. Right click, select new and string. The string name is “network.protocol-handler.app.sop” and the value is “qsopcast”. It should now send sops to the modified version of QSopCast ready to be launched.
