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

Given this, I took to finding a way that can block search results. Officially, there’s no way you can do that from within Google settings (which would have preserved that as you moved from machine to machine), but there are extensions for Firefox. Still looking for a Chrome one!

For Firefox, there are a few extensions. One is CustomizeGoogle, but it doesnt work in the latest version of Firefox.

The one that does work is SurfClarity. It allows you to list of a sites that should be filtered out. It doesn’t do it from the server-side which would save a 1kb of traffic, but nonetheless is good enough.

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

SELECT * FROM stories ORDER BY storydate DESC

Now for the challenge. What happens if you are required to get the top two stories from each source? One option is to first get the order of the sources, and then loop through each one of them:

SELECT DISTINCT source FROM stories ORDER BY storydate DESC

<loop “source” as “sourceid”>

      SELECT * FROM stories WHERE source = "{sourceid}" ORDER BY storydate DESC LIMIT 2

</loop>

Another option is to do the in MySQL itself! Unsure if there is a better way of doing this, but here’s mine using UNION and Sub Selects:

(SELECT * FROM stories WHERE source =
(SELECT DISTINCT source FROM stories ORDER BY storydate DESC LIMIT 0,1) ORDER BY storydate DESC LIMIT 2)
UNION
(SELECT * FROM stories WHERE source =
(SELECT DISTINCT source FROM stories ORDER BY storydate DESC LIMIT 1,1) ORDER BY storydate DESC LIMIT 2)
UNION
(SELECT * FROM stories WHERE source =
(SELECT DISTINCT source FROM stories ORDER BY storydate DESC LIMIT 2,1) ORDER BY storydate DESC LIMIT 2)

Explanation:

The bold section are subselects and form the WHERE clause of the query. Here  we want the first, second and third as per source, but only one at a time. Once we have two results per item, we use UNION to join them together.

One thing to note though. Even though it returns the latest two stories per source, the final table is not sorted by storydate! This can be done using PHP sorting techniques. Is there a way of doing this one time in MySQL?

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!

Class Ext.grid.GridDragZone

…

onDrag( Event e ) : void

Abstract method called during the onMouseMove event while dragging an object.

Parameters:

e : Event

the mousemove event

Returns:Class Ext.grid.GridDragZone

void

In this case, GridDragZone is part of GridView which is part of GridPanel. Accessing it will be, GridPanel->GridView->GridDragZone.

The GridDragZone gets implemented for a GridPanel when you set enableDragDrop to true, but it only becomes available when the grid renders, so:

var grid = new Ext.grid.GridPanel({
    // etc
});

grid.on('render', function(obj) {
    obj.getView().dragZone.onDrag=function(evt){
        alert('being dragged');
    }
});
