Solution:

• Press Ctrl+F1 to go to a terminal screen
• Login with your username and password
• sudo mobprobe -r psmouse
• sudo modprobe psmouse
• Ctrl+F7

This removes the mouse ‘driver’ from the kernel, and re-adds it. Wallaa!

After following all the steps, I got hit with:

W: Failed to fetch http://repos.zend.com/deb/ce/dists/ce/Release
Unable to find expected entry  non-free/source/Sources in Meta-index file (malformed Release file?)

Kept trying sudo-apt-get update whilst cursing Zend, and still the same.

Solution: Disable the sources repository in /etc/apt/sources.list.

#deb-src http://repos.zend.com/deb/ce ce non-free

Next, trying to install, and keep getting dependencies issues. There are two (old files) that need to be downloaded, and then everything works fine:

• libkrb53
• libmysqlclient15off

They were in older distributions, but no longer are!

Once those two files are manually installed (sudo dpkg -i), the rest is plain sailing.

1. I love the way it allows one to show an inbox for each account. I do not need to filter them, or create labels.
2. The ability to set a limit on incoming mail. Once activated, it only downloads the first 50kb of each email giving an idea of what the email contains, and it saves the frustration of downloading emails with large attachments, particularly from people I don’t know.

However, the one mistake I often make is clicking “Write”, type in the email, and clicking send, without checking that I’m sending it from the right email address. Fortunately, another great thing with Firefox and Thunderbird is extensions, and there is one that fixes that called Correct Identity.

It allow one to set an alternative default email address for writing an email. Eg. The account is support@…, but whenever you send out email from that account, it should be from tohir@…, that’s the issue it solves!

http.request.uri contains "php" ||  http.content_type == "text/html"

This effectively reads, only log items where:

1. The HTTP request contains PHP, OR
2. The HTTP response is “text/html”

Useful, dont have to wade through whats an Ajax response, bypass images, etc. One thing that would be nice would be if the area that shows the filter expression was longer!

Firstly, you need Ruby:

sudo apt-get install ruby

Thereafter (without sudo):

gem install haml-edge

This will install Haml and Sass into your directory, but at least you will have access to the latest version. Message that appears:

WARNING:  Installing to ~/.gem since /var/lib/gems/1.8 and
 /var/lib/gems/1.8/bin aren't both writable.
WARNING:  You don't have /home/tohir/.gem/ruby/1.8/bin in your PATH,
 gem executables will not run.
Successfully installed haml-edge-3.1.49
1 gem installed

You can test that it is the latest version by:

~/.gem/ruby/1.8/bin/sass -version

Which should return:

Haml/Sass 3.1.49 (Bleeding Edge)

Lastly, there is a nice command to watch files and auto generate an updated version:

~/.gem/ruby/1.8/bin/sass -t compact --watch [inputfile]:[outputfile]

like:

~/.gem/ruby/1.8/bin/sass -t compact --watch browseView.scss:browseView.css

This isn’t the answer, but a way of how to get access to the full response:

Right Click on the Packet in Line-based text data, then choose Copy > Bytes (Printable Text Only).

This will place the full response, and you can paste it in a text editor.

However, after reading Deconstructing Nautilus and rebuilding it better, I have to admit, I enjoy it. Why?

Even though I tend to browser elsewhere by typing in the path, the UP button is probably the most used button by myself. Switching to the location bar provides no alternative, but keeping the button bar allows one a form of up button.

Secondly, CTRL+L is probably something I can live with.

Given the whole debate around this, the lesson I believe is that don’t ignore your existing users. If you are going to change something, inform your users!

Given the opensource community spirit, it wont be long before someone does a quick script to bring back the old toolbar. If you are looking to do that today, have a look at: https://help.ubuntu.com/community/RestoreNautilusLocationBar

For Ubuntu users, the recommended alternative is Wireshark. Wireshark is noted as being more powerful than Fiddler, but the focus will be on the features most commonly used by web developers for tracking.

Installation

Wireshark is found in the Ubuntu repositories, so simply search for wireshark in Synaptic, or enter sudo apt-get install wireshark

Usage

Under Applications > Internet, you will notice there are two options. Wireshark and Wireshark (as root). Run the second one (as root) as this gives you more data to track.

After wireshark has started, the process is straightforward:

1. Choose which network interfaces to capture traffic from
2. Start capturing
3. Filter captured requests

1. Choosing which network interfaces to capture traffic from. From the menu, choose: Capture > Interfaces

This will bring up a list of network devices.

2. Since my work involves debugging work off my laptop (http://localhost etc), I only start device lo (127.0.0.1). This is useful as it immediately ignores all other traffic.

3. The one thing you will notice is that fiddler will log both the TCP and HTTP requests. For the purpose of debugging AJAX, etc., we are only interested in HTTP requests, TCP requests are not required. These can be hidden by adding a filter.

In the field next to Filter:, enter http and click on Apply.

The steps will now show all traffic coming on 127.0.0.1 via HTTP. The last step is picking up the AJAX parts for debugging. Notice that for each request, there is a response. Unlike Fiddler, Wireshark does not combine the request and the response. So click on the response line, and then expand the Line-based text data row. This will show the text of the AJAX response.

Conclusion

Wireshark takes more steps than Fiddler, and Fiddler is a more focussed program than Wireshark. Wireshark also captures traffic without having to install a plugin into firefox, etc., so it’s useful for debugging applications as well. The biggest improvement to make Wireshark truly replace Fiddler is to turn off truncation of the response text. Wish I knew how!

1) Access to original .air file

If you have access to the original .air file, run it and it will give you a screen with options to either Uninstall, Run Now or Cancel. Simply click on Uninstall.

2) Use Synaptic Package Manager

A second more easier approach (particularly if you lost the .air package) is to use Synaptic. From the sidebar, simply choose: Status > Installed (local or obsolete)

Discovering this makes me less hesitant to try our different AIR apps, trying to find out which one works best.

In a terminal, enter:

sudo apt-get install cups-pdf

It will ask you for your password when you press enter. Or in Synaptic, do a search for: cups-pdf.

Now one step that has to be done manually otherwise it doesn’t work. In your home directory, create a folder called PDF (all in caps).

After this, you’ll see an option for PDF in the printer’s list, and printing to PDF.
