Ubuntu Tweak is a tool for Ubuntu that makes it easy to configure your system and desktop settings.

Ubuntu Tweak allows a wide variety of customization and one is able to easily remove unneeded applications which just seem to fill up memory. It provides configuration for the following system sections: Applications, Startup, Desktop, System.

It’s maintained by a single developer who has a passion for open source software and he regularly releases updates for the application.

It’s really easy to install and one can install it using the following 3 methods:

1. Download the actual source and then manually install with a batch script

   ubuntu-tweak_0.4.3.orig.tar.gz

2. Download the Debian installation file and just run it

   ubuntu-tweak_0.4.3-1~intrepid1_all.deb

3. Or, use apt-get in the command line. This is what I used and it installed quickly and without any problems

   sudo apt-get install ubuntu-tweak

The site which I am talking about is http://bd4d.com, which stands for By Designers 4 Designers is built using the seagull php framework with the new cms module

General comments

Media Temple Installation

During the live installation I encountered a few problems, most of which related to permissions of files on the server:

The main one however were the permissions of the /var/lib/php/session/ folder – it has to be writable

Plugins that I found really useful during development

There were two firefox plug-ins that I found very useful during development of the site:

Colorzilla – gives you # codes for colours on any webpage
IE tab – allows you to open up ie7 tabs within firefox, which is great for cross browser compliant xhtml/css

Thanks to the developers of these two add-ons

Paypal

The site has a payment gateway for listing jobs and events which has transaction processing done by Paypal.

In terms of project mistakes, this was one of the biggest we made. The support that James received from Paypal was extremely poor and the general documentation which they supply is often out of date and incorrect. I am amazed that they have become such a successful company, when it is so difficult to integrate their transaction processing into one’s site.

However after a lot of waiting for accounts to go live, numerous queries, emails, phone calls and a lot of frustration, we did eventually get the transactions working. It is working fine now, but it was definitely not worth all of that hassle.

I would be interested to here about other experiences from developers using Paypal – hopefully you had a better one than we did.

Site Features

Showcase

The section of the site that I am most proud of is the Showcase section, which has flash and movies of some really cool clips which the bd4d guys have done. The section allows comments to be made on each of the movies and I think it looks pretty slick – even if I say so myself

To get the section functioning, I used the following:

A comment manager which Dmitri initially developed and then I adapted that code to be used for the site.

To prevent spam on the site I used captcha package from the php pear library

And I used the following code in the template to hold the movies/flash files:

< object width="550" height="400" >
< param name="movie" value="{webRoot}/themes/bd4d/showcasemovies/
{oItem.media}" >
< param name="quality" value="high" >
< embed src="{webRoot}/themes/bd4d/showcasemovies/
{oItem.media}" quality="high" width="{oItem.width}" height="{oItem.height}" autostart="true">< / embed >
< / object >

Events

The Events calendar uses the default seagull events module as a basis, but there where a few enhancements made to fit the requirements of the site. The majority of the development of this section was done by James and I think that he did a pretty good job of it.

The calendar looks pretty slick and works really well, also the backend of the seagull events module provides a lot of flexibility for administrators wanting to manage events.

Job board

The Job board uses custom managers in the default module and as I have mentioned in my section about paypal, it allows members of the site to post jobs for a fee. The transaction processing handles straight paypal payments as well as credit card payments which are verified by paypal.

Conclusion

As I mentioned in the introduction this site took way longer than expected and there were a number of hard lessons which the whole team learnt. But at the end of the day, the site looks pretty good and works as expected, so in some way it can be seen as a success.

Background

I developed the site using the Seagull php framework, using the publisher module (which has recently been superseded by the CMS module).

The publisher module requires a bit of hacking to make it run effectively, especially if the site requires content pages which have different layouts. But, overall the site works well and looks pretty good, even if I say so myself .

I have still had a number of difficulties, so for those of you who are planning on building a similar site, here are some of the things which I have learnt:

This is especially relevant if you are going to be using some of the following:

• Seagull php Framework
• Installing a site on a Media Temple Server
• Including a dynamic Google Map in a page using the api

Lessons learned

Tips for using the Seagull publisher module:

If you have various site sections which need to have different layouts, the best way of handling this is to create different content types for each different layout which is required.

Then create a different publisher template for that content type and specify the styling which you want for that particular section.

If you have any exceptions, then use a handler like this:

{if:isEqual(29,articleID)}

{end:}
{if:isEqual(30,articleID)}

{end:}
{if:isEqual(34,articleID)}

{end:}

I will endeavour to write a more in depth tutorial for this and put it on the Seagull wiki. Once I have done so, I will update this post.

Server Issues

The first issue which I encountered was trying to do an installation on a staging sub-domain on a Media Temple Dedicated Virtual Server, where php safe mode was turned on. I have written a post which is a guide on how to successfully remove these restrictions.

Browser Issues

As always, I encountered problems with cross browser compatibility. I discovered huge differences between IE6, IE7 and Firefox. The site looks best in Firefox, Safari and in IE6, but there are a few small differences on IE7.

I used this basic conditional block to include an IE hacks file for when a user views the site using IE.

< !--[if IE] >< style type="text/css" >@import "http://www.atalink.com/ themes/atalink/css/hacks/ie.css";< /style >< ![endif]-- > (Remove spaces)

Google Maps

Although this is not that difficult to implement, I found quite a useful site called:

Google Maps latitude, longitude Popup , which gives you the latitudes and longitude values for a specific location, which you use in the Google supplied javascript

Design

Although a designer may do a really good job and a client signs off a design, one has to be flexible enough to deal with client requests for changing of the layouts. Often the changes requested are quite valid and one should consider each request before just disagreeing.

Content

Again, I have been reminded about how important it is to have content ready and signed off, before beginning with development. It is amazing how much time can be wasted when you are waiting for pieces of content. Details about content should be agreed upon during initial agreements and no matter how difficult it may be, these agreements should be adhered to.

Conclusion

I have enjoyed working on this site and I have learnt a lot, in terms of development and in terms of communicating with clients.

On our most recent project we decided to try and use the php PEAR Quickform module. This has also proved to be a easy to use, yet powerful form generator and processor.One thing which I think needs improving is that when forms are generated, the HTML templates are table based. I am sure that the developers of this package are trying to implement this feature on later realeases, but the package we are using doesn’t generate semantically correct HTML forms.

However, to overcome this sticking point, we combined the smarty and quickform packages to produce semantically correct HTML templates, which have validation and processing ability.

The form generation, validation form processing are extremely quick and provide an awesome amount of felxibility when it comes to both presentation and application logic.

It is truly awesome what can be acheived using open source code.
Go php!!!
