Setting up a Virtual Machine on Ubuntu without KVM
I recently took a foray into the world of virtual machines on my Ubuntu server. I decided that since I could not use the well known KVM (my cpu does not have the proper extensions) I could use virtualbox. After installing it, I next learned how to mange the VirtualBox headless.
Main Installation Method
- Create a vm with the name ubuntu
VBoxManage createvm -name ubunutu -register
- Using the vm we just created limit its ram usage to 256MB, boot off the dvd and set the network interface card to use nat.
VBoxManage modifyvm ubuntu -memory "256MB" -acpi on -boot1 dvd -nic1 nat
- Create a virtual hard disk drive, at that location.
VBoxManage createvdi -filename "/var/vbox/ubuntu.vdi" -size 5000 -register
- Add the previouly created hard disk drive to the actual virtual machine.
VBoxManage modifyvm ubuntu -hda "/var/vbox/ubuntu.vdi"
- Register the ISO with the virtual machine.
VBoxManage registerimage dvd /var/vbox/ubuntu-10.04-server-i38.iso
- Modifying the virtual machine to use the ISO.
VBoxManage modifyvm ubuntu -dvd /var/vbox/ubuntu-10.04-server-i38.iso
- Finally, we start the vm and the real fun begins.
VBoxHeadless -startvm ubuntu
Your new virtual machine is now running, however we need an application that can allow us to install the actual operating system. On my Ubuntu desktop, I use gnome-rdp, you retrieve the ipaddress of the virtual machine, and type in port and after confirming, you will see the new OS booting from your server.
Alternate Installation Methods
Additionally, there are two other methods I came across that allow configuring a virtual machine easier with the use of a gui or web manager. The first is enabling X Server forwarding through ssh and the other is PHP Virtual Box. PHP Virtual Box is a a web based application which uses Virtual Boxes built-in api to interact with virtual box.

With some many webdevelopers/ designers/ graphics people all making websites how is a company or anyone for that matter to find someone to make their site?
1. Assuming a WYSIWYG editor can create a great website
Using a program to code your site will only result in jarbled code that no person or search engine, for that matter can understand. I have times where I was hired to move a website created with such a tool, into a application and it was easier to copy paste, and recode links, etc.
2. Slicing an image in Photoshop and exporting it as an html is “good enough”.
Photoshop does not know that using CSS you can repeat an image several thousand times, which reduces the time a downloading a site takes. In most cases, graphic designers do not have the knowledge to make optimization choices that can improve a sites speed.
3. A certain software package will make me better.
I have heard this one at to often, people believe that if they use a high end software package they can make sites that are wonderful..
4. Tabled layouts are fine to use for site layout.
Although tables have their time and place, DATA ONLY. Designers believe that using them is the best way to code a site.
Are you a developer or a graphic designer and how do you like dealing with the otherside of the web?

Category: Helpful Tips | No Comments »4 Ways to Reduce Bounce
Bounce rates are quickly becoming the metric people value the most.
What does “Bounce Rate” Measure?
By logging into any analytics software like Google Analytics or Piwik, you will find a wealth of information. One such piece of information is the Bounce Rate. The Bounce Rate, measures how many people left your site after seeing one page.
As previously mentioned these tools provide tons of information, some which is more useful then others. One such statistic, “unique visitors” tells how many new visitors viewed your site during a certrain period time. However, sites like Digg, StumbleUpon and others can bring large numbers of visitors, however those visitors will commonly view one page and immediatley leave. This does not help your build a customer base, create community or further your goal for creating the site. Sites like these can negatively affect your bottom line.
What is a good bounce rate?
A bounce rate of 0% would be best, meaning everyone who visits your site viewed more then one page hopefully completing your sites “goal action”. However, not everyone who visits your site will contiune surfing your site. Guidelines suggest the follwoing standards:
- Under 30% – Keep up the good work!
- 30% – 50% – Needs work.
- 50% + – Needs serious improvement.
Reducing site bounce rate
A few tips to help improve your site’s bounce rate, can go along way in improving your site’s chances of visitors going deeper.
Provide Relevant Content- The person visits your site but what are you going with their attention? Have other content they can visit to entice them to visit your site deeper.
Have Clear Navigation – A user does not want to visit your site if they can not figure out how it works. Users are looking for navigation that can use quickly and easily without a lot of fuss or errors.
Test your site – Present your site to as many different users as possible. Watch them visit your site, their actions will provide a wealth of knowledge about your site’s usability. What appears to be straight forward to you, is not always so to your site’s visitor.
Establishing a hierarchy to your site helps direct users around your site.
Expose the next step – Highlight the action you want your users to follow. If you want them to contact you, highlight or otherwise differentiate your contact link. This acts like a magnet to pull the user to complete the action you want.
Are you monitoring your site’s bounce rate? What is it? What have you tried to improve it?

Where are these entries coming from?
After creating a website with a guestbook I started noticing entries which were not left by a person. The name field was filed by an email address ie) “dfjkdlkjfkljd@hotmail.com”. The comment would contain jiberish like “auto auto something nothing”, and they were repeated quite often.In a few hours I have 10 entries that were from unknown origins. Once, I noticed the entries, I figured removing the “submit” button would stop the entries temporarily until a better solution could be found. That was wrong, I will explain how it was completed later on.
Resolving the mystery entries
I first, had to access the database and remove the spammed entries. To stop false entries, there are two main solutions.
- Improve the server side validation
- Use a Captcha
Server Side Validation
My first option and the one I choice, was to improve my server side validation. I realized they had a copy of the form and were submitting entries, so I improved what the server would approve. Originally, it was set to allow any thing that had more then 3 characters. After the update, no symbols would be allowed in names. This solved my problem until the people figure it out and change their methods.
Captcha
A much better method is to use a Captcha. Websites like Myspace and Facebook have increased their usage of them to stop spam on their sites.
You enter a code the website generates when visit the page. The spambots can not read the code, and as a result are unable to make a post.
End Result
I fixed the server side validation and was able to keep the nasty people away from my posts.
Have you had any problems with spammers in emails or on websites? What did you do to remove them?

When starting webdevelopment, several tools can aid in your work. Some developers enjoy using the standard while others require a little more assistance with coding. The tools come in two variations, the WYSIWYG variety and the straight forward text.
WYSIWYG – What you see is what you get
These generally are for entry-level people to create a website that meets their needs. The software takes care of all the background coding while advanced web designers, hand code everything. This allows higher quality, cleaner code, which allows higher grades of customization improves SEO (search engine optimization). This improves your sites overall position on search engines like Google, Yahoo and others.
Notepad++
Notepad++ is not a WYSIWYG editor, so this is for users who know how to program code. Nice program which has an easy way to add additional scripts
Eclipse
Eclipse may require a little fine tuning to get PHP scripting to work. In Linux Eclipse is a breeze and runs smoothly, although in Windows it appears to hog system resources and bring everything else to halt.
Intype
Intype appears to still be in beta, but shows promise a program that supports both Linux and Windows.
This concludes our list of free editors, do you have any you use?
