Acid 3 Tests

The Acid 3 tests cover browser compatibility with web standards - follow this link for more information and this link to test your current browser. Ideally the browser tested will score 100/100. Tests above run full screen - not in a frame.

Safari Tools

Safari contains a set of tools to help web developers as they test web pages.  Normally these are hidden from view, located in a menu labelled Debug.  To activate them open Terminal in folder /Applications/Utilities and type:

defaults write IncludeDebugMenu 1 .  To switch off run the command again but replace 1 with 0.

Tools include a basic JavaScript debugger, tick the Debug menu option 'Log Javascript Exceptions' and select 'Show JavaScript console' to view bugs as the happen.  The tools also include Snippet editor which is a simple graphical HTML editor where you can amend code and see the Safari render effects right away.? There is also a Page Load Test feature which gives feedback on how long it takes to load a page.

User Agent submenu allows Safari to assume the indentity of 'IE' or 'Netscape' when connecting to sites that are wrongly designed just for these browsers when Safari can render the pages perfectly.

OS X Local Web Server

NOTE: OS X comes with Apache Web Server and 'Document root' is the location where the files are shared from the file system and is similar to the traditional names of ‘public_html‘ and ‘htdocs‘. OSX has historically had 2 web roots one at a system level and one at a user level – you can set both up or just run with one.

The user level one allows multiple accounts to have their own web root whilst the system one is global for all users and in OS X Yosemite the 'System Level Web Root' - the default system document root is still found at - "http://localhost/" in a browser.

The files for the 'System Level Web Root' are shared in the filing system at - /Library/WebServer/Documents/

Files for user level web root are stored in folder '~username/Sites' as before, but the 'Sites' folder may not be automatically created on new systems, ours is left over from earlier OS X releases where it was created as part of user account setup.

This would normally be reached via 'http://localhost/~username/' if Apache is set up to run web pages in this folder. We just run the files manually under 'Sites' and use our UK2 official web site web server for further testing.

Wireshark network traffic tool

ADSL Tests - Wireshark v1.10.2 PING / DIG Stanford Networking Course - very useful information  

To get a more accurate estimate of your average broadband performance, always run more than one test. One of the important factors in broadband performance is the length of the 'copper wire' from the service providers equipment to your actual phone socket. As most exchanges are becoming digital and interconnected by fiber optic then the only copper wires should run from the exchange to your site. Telecoms companies can tell you what the effective line length is for the copper wire (optic has not got any significant attentuation here) - mine was 1.88km only a few months ago, however a new cabinet was installed just down the road which would have a fibre optic connection to the exchange. This has resulted in speed increasing from around 6 to almost 16mb.
