Before you can install programs on Ubuntu LINUX residing on a VMWare Virtual Machine, you need to install VMWare tools. In turn, you must install the gcc compiler for C++ before this can be installed. as follows:
sudo apt-get install build-essential linux-headers-'uname -r'
sudo apt-get install gcc
If you have no Internet access the above commands will give an error so you need to mount the CD as follows:
sudo apt-cdrom add
sudo apt-get update
sudo apt-get install build-essential
Sometimes when installing VMWare Tools you may encounter the following error:
The directory of kernel headers (version @@VMWARE@@UTS_RELEASE) does not match your running kernel (version 2.6.35-22-generic-pae). Even if the module werre to compile successfully, it would not load into the running kernel.
This error can be overcome by locating the Version.h file. In Ubuntu Server 10.10 this is located at lib/modules/2.6.35.22-generic-pae/build/include. Add the following line to this header file:
#define UTS_RELEASE 2.6.35.22-generic-pae
The command uname -r gives the version you should use.

Fusion Charts & Internet Explorer: Refresh Issue |

When using a Web Page containing a Fusion Chart in Internet Explorer you may sometimes encounter a issue where old data appears to be cached and displayed on the chart. This is a refresh issue but is easily overcome by appending the current time to the dataURL attribute as follows:
dataURL=./Data.xml?CurrDateTime=$cur_time
The current time can be accessed using a language such as PHP or JavaScript. In the above example we used PHP to access the current time and assigned this time to a variable:
$cur_time = time();
The full tag for the chart is as follows:
<object classid=\"clsid:d27cdb6e-ae6d-11cf-96b8-444553540000\"
codebase=\"http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0\"
width=\"1000\" height=\"300\" id=\"Trend\" >
<param name=\"movie\" value=\"./FCF_MSLine.swf\" />
<param name=\"FlashVars\" value=\"&dataURL=./Data.xml?CurrDateTime=$cur_time&chartWidth=1000&chartHeight=300\">
<param name=\"quality\" value=\"high\" />
<embed src=\"./FCF_MSLine.swf\" flashVars=\"&dataURL=./Data.xml?CurrDateTime=$cur_time&chartWidth=1000&chartHeight=300\" quality=\"high\"
width=\"1000\" height=\"300\" name=\"Line\" type=\"application/x-shockwave-flash\"
pluginspage=\"http://www.macromedia.com/go/getflashplayer\" />
</object>

When installing Documentum you may encounter the following error:
"DiPADbInstall failed! - Runtime execution failed with child process"
This occurs if you have Microsoft .NET Framework 4.0 installed on your system. Install .NET 2.0 instead and the product will install successfully. As a precautionary measure you should also install Java JRE 1.5 instead of Java 6.

When parsing dates in JavaScript it should be noted that Date.Parse() doesn't recognise strings with dates in the form dd-mmm-yyyy. One workaround is to first replace the '-' in the string with a space as follows:
// Replace '-' with spaces. Note that /-/g ensures that ALL '-' in the string are replaced.
strToParse = strToParse.replace(/-/g,' ');
// Display the parsed date.
alert(Date.Parse(strToParse);

In the context of computer networks and pervasive computing, the term 'smart object' is frequently used. However, it can be difficult to define this term. In essence, a smart object is any computing device that can provide real-time data on an ecosystem such as a natural environment or a city. Smart Objects can be roughly categorised as sensors (including wireless sensors), meters (including smart meters), RFID and/or GPS. Their primary function is to enrich the quality and quantity of data for an ecosystem. Their practical effect is reduced consumption and improved efficiency. |
