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
Assumptions
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.

[How to] Create a bootable USB stick on OS X

A couple of days ago I decided to reinstall my operating system since it was failing. I quickly realized that the only functional system that I had at the time was my MacBook Pro. After a bit of Googling, I came up with a pretty straightforward guide, but they really could have formated it to make it easier to follow.

I’m going to run you through the same steps and you should be able to use this guide to create a bootable USB stick for Windows, Ubuntu, Fedora, etc.

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.

Nvidia patches a bug I’ve waited 9 months for…

I’ve been following an Nvidia bug that’s been affecting me for a while now and am happy to say that its apparently been fixed! I say apparently, because I’ve not been around my Linux box for several days (due to the holidays) and haven’t had a chance to confirm for myself.

If you have an Nvidia card, especially the 7300le model like I have, and have had difficulties using Unity 3D with the proprietary drivers, then you may have experienced this bug: [nvidia, 7300, 7400] display freeze when using unity desktop

Nvidia has just released an update which resolves this issue and it can easily be installed right away!

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:

 

Adium

 

Banshee Media Player

 

Eclipse

 

Google Chrome

 

Google Drive

 

Google Music Manager

 

Opera

 

Ubuntu Software Sources

 

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…

Hostnames

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:

Count

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.

Progress

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!

Urgency

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).

Quicklists

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.

Download

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:

python unity-opera.py

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

Options

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

python unity-opera.py –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 unity-opera.py opera

python unity-opera.py 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 unity-opera.py opera -qs

python unity-opera.py opera-next -qsu

Troubleshooting

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:
X-Ayatana-Desktop-Shortcuts=NewTab;NewPrivateTab;NewWindow;Mail;

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

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

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

[Mail Shortcut Group]
Name=Mail
Exec=opera -mail
TargetEnvironment=Unity

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.

Conclusion

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 Little I Use Windows

Here’s a funny screenshot that I took earlier today that shows how little I actually use Windows these days.

Its funny to me, because for a while now I’ve only booted up in Windows to manually run updates and quick virus checks with the occasional Steam gaming session.

I run updates and scans almost religiously, so I know that October 3, 2010 was the last time that I even used this partition. Thats nearly 4 months of booting only in Linux (Ubuntu and Fedora) on my Desktop.

I do, however, use Mac OS X now on my new MacBook though. I’ve still not gotten around to installing Ubuntu on it, but maybe one day I’ll stop being lazy and just give it a spin.

I’ve known for a while that I could finally cut the cord from Windows, but this just officially confirmed it for me. That said, I won’t soon be giving up my free (via School) copy of Windows 7 Professional. 😀
