Debugging PHP in Ubuntu using Eclipse

This guide walks you through the necessary steps to configure the Eclipse IDE for PHP debugging. This can be very handy, especially when you’re trying to resolve an issue in a complex PHP application or plug-in.

Things you’ll need

  • Eclipse
  • Eclipse PHP Development Tools (PDT)
  • Xdebug
This article assumes that you are configuring Eclipse and Xdebug for development on a localhost web server. If you are not, be sure to make appropriate adjustments to accommodation your needs. Likely the only changes you will need to make will be differences in connecting to your server verses localhost.

Quick Overview

For those that are unaware, Eclipse is a very popular IDE for developing in Java. However, Eclipse is much more powerful than that and can in fact easily be used for developing in many other languages including PHP.

Xdebug is a brilliant debugging extension designed for use with PHP. Once configured, Xdebug will allow you to remotely connect to your web server… or in my case connect to my development localhost web server. Rather than using crude echo and logging techniques to debug your PHP code, Xdebug allows you to literally step through and inspect values and function flows in real-time.

Making CSS UL Menu’s Browser-Consistent

If you’ve ever made a web site and wanted it to look consistent from one browser to the next, then you’re well away of the difficulties that are involved. Fixing these sorts of styling issues can be a major annoyance, however, I like to hunt down issues on my own pages from time to time and stand up to the challenge.

One issue that I can across today was dealing with horizontal menu positioning using unordered lists (<UL>) and some positioning. The positioning wasn’t consistent between browsers or even operating systems.

Ubuntu Software Center vs. Mac App Store

As many of you may already know, Mac OS X now comes installed with a “Mac App Store”. Ubuntu also comes installed with an “Ubuntu Software Center”. Both of these applications serve the same general functionality in very similar formats, but I’m going to take a look at what needs to be improved in the Ubuntu Software Center.

First off, lets take a look at both of these applications from a first impressions point of view. Its pretty obvious at a glance that the user interface of these applications are eerily similar. It’s also pretty obvious that one app has received a little more attention to detail and aesthetics.

Create a Bootable Windows 7 x64 Install Flash Drive from 32-bit Windows

Creating a bootable Windows 7 x64 flash drive from within a 32-bit install of Windows is not as straight forward as it may seem. I recently had to go through this process myself, so I’ll document the steps below.

Things you’ll need

  1. Windows 7 x64 disc image
  2. Windows 7 USB/DVD Download Tool
  3. 32-bit bootsect.exe

Create the installer

What do you install in your Ubuntu?

I’ve been keeping lists for a few years of the applications that I install every time I do a fresh install of Ubuntu. I recently made a new list for Ubuntu 11.10

  • Cheese
  • Chromium Web Browser
  • CompizConfig Settings Manager
  • Dropbox
  • EasyTAG
  • Enable Commercial DVD Playback
  • FileZilla
  • Geany
  • Opera Web Browser
  • RapidSVN
  • Spotify
  • The GIMP
  • Ubuntu Restricted Extras
  • VLC
  • Wakoopa

The applications that I install haven’t changed a whole lot over the years, but it leaves me wondering what applications make the cut for others!


Submitting Anonymous Usage Statistics

Being a software developer myself, I tend to pay attention to application functionality and options a little more than the average end user. I’ve noticed that over the last few years when I encounter an option to ‘submit anonymous usage statistics’ I gladly and immediately enable it.

Knowing that you can gain valuable information about the way your end users are using your product, it makes sense for a software developer to include this option and frankly I’m baffled that its not available in most all applications.

I’d like to use this post for two reasons:

  1. To encourage you and others to consider enabling this option in order for developers to get the accurate information that they need to make their product even better!
  2. To maintain a list of these options in various applications that I stumble upon so others are aware.

As I gradually increase the number of applications, feel free to point out applications that I’ve missed and I’ll add them to the list!

Application List:




Banshee Media Player




Google Chrome


Google Drive


Google Music Manager

Using Synergy with Mac and Ubuntu

This is just a quick guide for those of you who also use both Mac and Ubuntu (or really any flavor of Linux) side by side. If you’re not already familiar with Synergy, it’s a small application that connects your mouse and keyboard to one or more machines for a more continuous experience.

Mac and Linux use a graphical front-end for Synergy known as QuickSynergy. Here’s how to get it configured for use between Mac and Ubuntu…


You can find the hostnames to use simply by opening a Terminal window, or if you’re unsure still, simply type hostname and press enter. 😉

If you used the hostname command in Ubuntu, you probably noticed that the “.local” part is not printed out, but it is necessary when dealing with Mac OS X.

Connecting the Two

After selecting the system you’d like to share, configure the Use or Share tab as necessary similar to the examples below:

After configuring Synergy/QuickSynergy you’re all set to start making your life easier!

Unity Opera!

With Unity in the recent spot light and a little free time on my hands, I decided it was time to dabble with the Launcher API. What better combination that my two favorite pieces of software: Unity in Ubuntu and Opera!

With my Unity Opera script, you’ll be able to get extra functionality for Opera by simply downloading a script and adding it to your Startup Applications list. No technical modifications necessary!

The Launcher API provides four features at the moment: Count, Progress, Urgency, Quicklists.

At the moment I’m only able to implement functionality for three of these, with the exception being Progress. In its current implementation, Unity Opera has the following features:


The total number of tabs you have open appears on the Launcher icon and is updated in real time as you open and close tabs.

One item to note here is that Opera’s Private tabs are not included in this tab count. Since information about these tabs and their contents are not stored anywhere on your computer, Unity Opera has no way of discovering them.


At this point in time, the progress functionality for this script is not available. Until I find a way to programmatically determine download progress in Opera, I will not be able to implement this.

If you have any information regarding a way to implement this feature then please let me know!


When browsing the net, not every link you click on is from inside the web browser. Sometimes you click a link from an instant message, mail client, Gwibber, etc. This is where urgency comes into play.

Typically clicking these links automatically opens the tab in your browser, but it doesn’t always pull you’re browser into focus. When this happens, you may not know which browser the link opened in or if clicking it was even successful.

When Opera is not in focus and a new tab is opened, the Opera icon in the Launcher now enters urgency mode and wiggles onces. An urgency highlight is also applied to the icon and a small attention reminder in the upper left corner until you focus Opera again (this clears the urgency setting).


Previously I shared a tip on how to customize your Quicklists for Opera. That method meant that you had to manually open and edit the desktop file.

This is no longer the case, as these features are already built into Unity Opera.

On top of that, your Speed Dial items are also appended to the Quicklist, making your life that much easier! 😉

If you use Opera’s built in Mail client, also known as M2, then you will see an Opera for Mail, which is intended to open M2 directly. At the moment, this feature doesn’t work as intended, but hopefully in due time it will.

Download Unity Opera

Unity Opera is written in python and can easily be updated and maintained. I suggest you save and extract it to your Home directory and use it there, but you are free to place it anywhere you wish.


Running Unity Opera

You can run Unity Opera in one of two ways:

1. The easiest way in my opinion is to simply add it to your Startup Applications.

To do this simply open your dash and search for ‘Startup Applications‘. Once there, click ‘Add‘ and fill in the blanks!

To run Unity Opera on startup, I place the script in my home folder. You can place it where ever you wish, but if you pick a place other than your home folder then you will need to provide a full path the script in your startup command.

An example of what I use is as follows:


2. The other option is to open a terminal when you want to use this script and run the command above.


This script has several options. For help and more information type:

python –help

This script accepts two optional args:

1. Opera Channel: This is used for setting Unity Opera to run against regular Opera and the new Opera Next channel. By default, if you exclude this arg, Opera is set as the browser to run against. Examples of this command include:

python opera

python opera-next

2. Enable features: This is used to enable specific features. You can enable only basic quicklists [q], quicklists with Speed Dial entries [qs], tab count [c], urgency notification [u], and progress [p].

As mentioned before, progress is not functional at the moment, but I’ve built the script with this feature ready to include as soon as I find a way. 😉

This second argument requires the use of the first argument. Examples of this command include:

python opera -qs

python opera-next -qsu


If you experience trouble with this script, please try running it from a terminal to see if there are any errors output to the console. If so, copy and paste these in the comments below and I will take a look at them.

Quicklists for Opera in Unity

Thanks goes to Jorge Castro and a recent post of his about Quicklists in Unity.

After reading his post and seeing how easy it was to add new Quicklist entries, I decided to give it a go with Opera.

As you can see, my efforts were successful, but there are many more list items you could add to customize Opera’s Quicklist to suit your needs.

Get It for Yourself

If you’re using Ubuntu 11.04 with Unity and want to customize this menu for yourself then just follow follow these simple steps.

1. Open a terminal and type the following (and enter your password when prompted):
sudo gedit /usr/share/applications/opera-browser.desktop

2. Scroll down to the bottom of this open file and paste the following:

[NewTab Shortcut Group]
Name=New Tab
Exec=opera -newtab

[NewPrivateTab Shortcut Group]
Name=New Private Tab
Exec=opera -newprivatetab

[NewWindow Shortcut Group]
Name=New Window
Exec=opera -newwindow

[Mail Shortcut Group]
Exec=opera -mail

3. Save and close the text editor. You may need to restart Unity or your computer before changes take effect.

Customize your Quicklist

If you’d like to add more items to the Quicklist, simply add a shortcut name for it in “X-Ayatana-Desktop-Shortcuts" and create a "Shortcut Group" for it.

A couple of things that I considered adding were Gmail and Google Reader so that they simply open in new tabs. I’m sure you can find other useful shortcuts to add or maybe even more Opera command line options!

Remove your Changes

If you don’t like the Quicklist items that you’ve added, all you need to do is open the opera-browser.desktop file and remove the lines that were added. Save, close and voila.


Quicklists are great, but they would be more useful with Opera if we were able to select from a list of open or recent tabs.

The new tab and window shortcuts that I’ve added are enough for me at the moment, but I would really love to see them added by default in the near future!

How to setup and use Tor Anonymity in Ubuntu

Just before the new year, I saw a news article by Wired that highlighted flaws found in the Tor Anonymity Network. I had never used Tor, but I knew what it was, the benefits it could provide, and a bit about how it worked.

With a little free time on my hands I decided to set it up and see what all the fuss was about. At the time I was installing the Tor components in OS X, but I was curious about installing it in Ubuntu and the resources and instructions that I came across were not as straight forward as they could have been. That is where this post comes it, to provide a simple step by step guide with no fuss.

What is Tor?

This is how Wikipedia explains Tor:

Tor is a system intended to enable online anonymity, composed of client software and a network of servers which can hide information about users’ locations and other factors which might identify them. Use of this system makes it more difficult to trace internet traffic to the user, including visits to Web sites, online posts, instant messages, and other communication forms. It is intended to protect users’ personal freedom, privacy, and ability to conduct confidential business, by keeping their internet activities from being monitored.

What does it look like?

Tor itself doesn’t have a graphical user interface (GUI), but there is an application known as Vidalia which provides a nice and simple user interface for controlling all of your Tor needs.

When installing Tor in Ubuntu, you will need to install 3 components: Tor, Polipo, and Vidalia. Tor and Vidalia should now be obvious to you (since I’ve explained that Vidalia provides a GUI to Tor).

Again, according to Wikipedia here is what Polipo is:

Polipo is a fast and lightweight, forwarding and caching proxy server, SOCKS proxy and computer software daemon.

Install Tor in Ubuntu

This is really quite simple and I could easily provide a simple bash script to automate all of this for you, but that would mean that I would have to maintain it and that you wouldn’t learn anything. 😉

For simplicity, I will write this guide assuming you are using Ubuntu 10.10, aka Maverick. If you’re using a different version, make sure you change the necessary bits below.

  1. Open “Software Sources,” select the “Other Software” tab, click the “Add” button at the bottom and paste the following:

    deb maverick main

    Click “Add Source,” then click Close. When it asks if you want to Reload, click yes and ignore any errors for now.

  2. Open a Terminal and add the Tor Repository keys and update Apt:

    gpg –keyserver –recv 886DDD89
    gpg –export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add –
    sudo apt-get update

  3. Install Tor, Polipo, and Vidalia:

    sudo apt-get install tor tor-geoipdb polipo vidalia -y

    When prompted during the installation of Vidalia, select the option to permanently replace (or however it is worded).

  4. Download a pre-made config file for Polipo:

    sudo mv /etc/polipo/config /etc/polipo/config.bak
    sudo mv polipo.conf /etc/polipo/config

  5. Now Stop and Restart both Tor and Polipo for safe measure:

    sudo /etc/init.d/tor stop
    sudo /etc/init.d/polipo stop
    sudo /etc/init.d/polipo start

    Open the application Vidalia when you would like to connect to the Tor network. If you want it on by default, you can always set Vidalia to autostart with your computer.

  6. All thats left is to configure your Applications to use the Tor proxies! If you don’t adjust the network settings of your applications to use the Tor proxy settings then you’re not using Tor at all. You can confirm that Tor is indeed working by visiting the Tor detector page.

If you run into issues for any reason, check back through the steps listed above. If that still doesn’t fix them, you might check the Community Ubuntu Documentation on Tor page or the official Tor for Linux/BSD/Unix page.

Configuring applications to use the Tor proxies

There are 2 types of configurations for Tor:

  1. HTTP or HTTPS – Typically used for web browsers such as Opera, Firefox, Safari, Google Chrome, etc.

    Port: 8118

  2. Sockets – Typcially used for instant messaging applications such as Trillian, Digsby, MSN, AOL, Empathy, Pidgin, etc.

    Port: 9050

Nearly any application that allows you to adjust network settings by using proxies can make use of the Tor Anonymity Network. Configuring your application of choice is a matter of selection to use HTTP or Sockets.

If you’re unsure, use trial and error. 😉

A great note that I came across on the Community Ubuntu Documentation page for Tor that I think everyone should read carefully before using Tor is as follows:

What’s the use of having Tor and Privoxy setup without enabling your new anonymous proxy in your common web applications? At this time Tor only supports HTTP and HTTPS traffic, but still recommends using Tor in your browser’s proxy settings for all protocols as a hidden image link can give away your IP address if linked to an image on an FTP site.


Hopefully by this point you’ve successfully configured Tor for all of your anonymity needs. Will Tor works great, it only works great if you’ve configured it correctly.

Some Tor connections may be slower than others. If you’re experiencing a connection that is simply too slow for your needs or if you need a new ip address so you can get that file from RapidShare without having to wait for an hour, simply open Vidalia Control Panel and click “Use a New Identity.”

Remember that Tor can be used for Windows and Mac, and is more straightforward to install for them as well.

While there have been a few flaws exposed, as mentioned before, I would tend to think the risk of being identified over Tor is very low since the attacks would have to occur on the same network that you’re connected to. I typically only use Tor at public internet access points (which is where these attacks would be most likely to occur), but it can be very handy in many situations and will likely continue to be on the list of my apps to install for a long long time.

Opera 11 in OS X

This is a post that I started a couple of months ago, but finally just got around to revising (since Opera 11 has since been released) and finishing. Hopefully its all in tact. 😉

Being fairly new to Mac OS X, I was excited to install Opera and see how it compares to the default browser Safari as well as others such as Firefox and Google Chrome in terms usability and appearance.

While I hadn’t used Mac OS much since version 9 and then briefly OS X (with my old iBook before it died), I did remember that Opera didn’t exactly have the most elegant user interface. Nor did most other third party web browsers that I tested at the time. Then again, OS X wasn’t as refined then as it is now either. Keep in mind, these are my opinions and you are free to have your own. 😉

I was happy to find that Opera seems to have the most natural feeling user interface when compared to Firefox and Google Chrome, using Safari as the standard since most die-hard Mac users are likely familiar with it the most.

While I didn’t capture Safari in a view where the tabs are visible, the image above is a decent comparison of the browsers’ default address bars and navigation buttons.

As you can see, the buttons, address box and search box in Opera mimic those found in Safari quite well and are not much of a change at all for any ex-Safari user. The tabs used in Opera are also very similar to those found in Safari (pictured below), with the most significant exception being that they are flipped vertically and placed above the address bar (in Opera) rather than below (like in Safari).

While some people may prefer Firefox or Google Chrome over both Opera and Safari, the point remains that their designs are inconsistent with the overall look and feel of the OS in general. That’s not to say that Opera doesn’t have some inconsistencies of its own. There are a few of them, but most of what I’ve found are minor detail tweaks that are needed to perfect the skin.

Just to mention a few things that are stand out to me, the “New tab” icon size should be decreased slightly, retaining the Opera style while removing the unnecessary bold touch. If you compare this button to the same button found in Safari you’ll notice that Opera’s approach is a bit too bold and that changing this makes it more elegant looking (in my opinion of course).

The borders for the navigation buttons, address box and search box should all be slightly adjusted to match the colors used for these in Safari. There are slight inconsistencies among these, with disabled button borders being darker than enabled button borders.

Another inconsistency with Opera is that text boxes in the address bar are not highlighted with a blue glowing border when they are focused…as they are in Safari, Firefox and Google Chrome. Its difficult for me to see if this is advantageous or simply an oversight, however, the “pro-integration” side of me certainly thinks this should be fixed to match the behavior of other browsers in OS X.

Various icons throughout the user interface need to be desaturated to remove color for consistency. An example of this can be found in the address box with the drop down icon. If you look close, the drop down icon is actually blue whereas other similar icons, like the drop down icon in the search box, are gray scaled. This is also a bug I’ve seen in the Windows and Linux skins, but the OS that demands attention to detail is likely the one that this is most noticeable on.

The Speed Dial page, though it was “invented” before the other spin-offs, now uses a darker background that makes it feel a bit more familiar to Safari’s implementation. I find this to add to the integration effect, whereas previous Speed Dial background images felt out of place. On the other hand, Opera doesn’t boast comparatively appealing 3D thumbnails or features to those found in Safari. Instead, the Opera Speed Dial packs in a redundant search box and no immediate method of searching through your history (visually at that!) or displaying your top visited sites automatically.

With a default Speed Dial tab open, knowingly or not, you’re looking at three different ways of searching the Internet…all with the same available list of search engines. You can search from the address bar by simply prepending your search terms with a specific search engine “keyword”, from the dedicated search box in the address box or from the additional search box in the Speed Dial. If I had any influence on this design, I would remove both dedicated search boxes and make the address box smarter and more visually suggestive of performing a search when it is in use.

While I’m suggesting changes to the Speed Dial tab, why not take advantage of Opera’s ability to generate thumbnails of pages to give the user a visual of the pages they are searching through just like Safari is capable of? With the ability to generate these thumbnails already, there is no reason why Opera shouldn’t implement a similarly more appealing visual search of previously visited sites.

As I said before, all browsers have their problems with UI design and integration, especially in Mac OS X. Of the available browsers for this platform, the one with the most features and the best OS X integration is far and away Opera 11. The performance improvement isn’t bad either, with my test results showing Opera 11 beating out Safari 5.0.3 easily in the SunSpider benchmark. You can take my opinions with a grain of salt if you wish, but you should undoubtedly give Opera 11 a spin if you haven’t already!
