Browsershots - Get a view of your site on multiple browsers

Wednesday, June 4th, 2008

I was recently reading about a wordpress plugin on askapache.com, when I came across a previous post which he had written about CSS Browser Screenshots.

The utility is called Browsershots and it’s kick-ass! Well that’s only if you are worried about what your site looks like on numerous different web browsers on different operating systems. Different strokes for different folks ;)

The application generates screenshots of your site in the different browsers and then you can download the pack of images and be uber critical about your CSS.

Finding a free MySQL database schema tool

Thursday, May 29th, 2008

MySQL Workbench

I was recently looking a a free database schema tool to produce a technical specification for a MySQL database. I downloaded and installed a number of freeware software tools, but most of them didn’t quite offer the functionality that I needed. Also, some of them were extremely “clunky” and need quite a lot of refining - not sure of the names of the software I tried, but thats not really the point of this post.

After awhile I came across MySQL workbench. I think its a great piece of software, especially since its free ;) The most useful feature I found was to be able to import a db schema from a .sql file and then the application gives a great representation of the schema. The one thing I didn’t find was how to show foreign key links between tables - If anyone can tell me how to do this I would be grateful.

So, if you’re on the lookout for a free tool to give a good representation of a database schema, then do go ahead and try MySQL workbench.

Spotify is really cool

Wednesday, May 7th, 2008

Spotify

Spotify, is a new digital music application which connects to the internet and provides the users with an absolutely massive music library. It is still in beta, but I have been fortunate enough to have been given a sneak preview into the capabilities of the application.

What does “Spotify” mean?
The name Spotify is a combination the words SPOT and IDENTIFY. Spotify helps you spot and identify the favorites you forgot about, or maybe didn’t even know you had.

The search feature is lightning quick and the range of music which is available is mind blowing. My only concern at the moment is regarding rights issues of the music which is available. I mean they have millions of songs available to stream free of charge, so is it legal? I suppose time will tell…

I just hope that the company releases Spotify soon, because I bet there are loads of music fans out there dying to get a copy of the software.

Kindo releases a private beta

Tuesday, September 18th, 2007

The team at Technovated has been working very diligently for the past few months to get a new application off the ground. Its called Kindo and we have finally released a private beta which is open to invitees only. If you would like to get onto the beta testers list, then submit your email address via the form on www.kindo.com.

We have also released a new blog on blog.kindo.com, so if you would like to keep up to date with our latest news, then please visit it. Comments are more than welcome ;)

Here are some snippets from two interesting posts on the Kindo blog

http://blog.kindo.com/2007/08/02/some-technical-details/en/

We’re having fun building the Kindo application and used a number of frameworks and components to achieve the finished result.

For the web framework we’re using Seagull which offers excellent integration with Flash through the AMF PHP request handling and easy integration with Ajax and Graphviz. For the Ajax interactions we use jquery exclusively, for Graphviz a heavily extended version of the PEAR lib of the same name. Working with the dot language has been interesting and a good opportunity to experiment with the subtleties of a genealogy graph.

http://blog.kindo.com/2007/09/04/welcome-to-the-beta-release/en/

A little while ago we released an Alpha to a small group of people, to gather valuable user feedback. Thanks to those great people, we’ve had our heads down improving Kindo, and as a result we’re releasing the Beta, and at the same time opening it up to a wider audience for more feedback.

Enabling rss feeds on a vanilla forum that doesn’t allow public browsing

Friday, August 3rd, 2007

Situation

I recently installed the Vanilla forum and set it up so that it would not allow public browsing, because the discussions there are top secret ;)

I then installed the Feedpublisher extension to allow for RSS2 and ATOM feeds.

Problem

I encountered a major problem though, the rss feeds were not accessible because the forum did not allow public browsing. I also saw that on the vanilla community forum, this problem had been rasied, but no-one had offered a solution.
Also, when trying to access the feed through the browser, one gets an authentication pop up box requested a username and password. When one enters the username and password into the respective text fields the following error message is displayed:

A fatal, non-recoverable error has occurred
Technical information (for support personel):

Error Message
An error occurred while validating user credentials.
Affected Elements
Feed.ValidateCredentials();

The error occurred on or near: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(u.Password = md5('foobar') or u.Password = 'foobar' )' at line 1

Solution

After quite a bit of playing around and testing, I found a relatively easy solution to the problem – typical a five minute fix for an error that keeps you busy for 2 hours!!!

Step 1


So firstly go to /extensions/Feedpublisher/default.php and make sure that the following section of code looks like this (line 60-73 )

if ( $Context->Session->UserID == 0 && ! $Configuration[ "PUBLIC_BROWSING" ] )
{

// Temporarily make the PUBLIC_BROWSING enabled,
// but make sure to validate this user
$Configuration[ "PUBLIC_BROWSING" ] = 1;
$Context->Configuration[ 'AUTHENTICATE_USER_FOR_FEED_PUBLISHER' ] = 0;

}
else
{

$Context->Configuration[ 'AUTHENTICATE_USER_FOR_FEED_PUBLISHER' ] = 0;

}

Step 2

Then login to the admin section of the forum go to settings > categories > $category edit

Then you need to check the “unauthenticated�? option in the “Roles�? and hot save. Do this for each and every category, unless you don’t want a specific category to be displayed on the feed.

This method fixed my problem, so I would be interested to find out if anyone else has a better solution. Also let me know id it doesn’t work for you – I hope that’s not the case though.

Reviewing a CMS solution developed on Mediatemple with the Seagull PHP Framework, including Paypal integration

Wednesday, July 25th, 2007

On Friday 20th July I finally deployed a site which we as a team have been working on for a number of months. Working on the project has been a huge learning curve and has taken way longer than ever expected.

BD4D

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.

Ensuring that favicons are displayed on your site

Thursday, June 21st, 2007

Favicons have become quite the norm on websites nowadays and I have encountered a few problems with them in the past, since browsers usually cache them and it takes quite awhile for browsers to update when a favicon is changed.

I used to just leave the .ico file in the document root and hoped that the browser would pick it up, but I have recently been told a much better way of ensuring that the correct image is displayed in the URL text field.

Place the file in the images folder and then refer to it in your the head of you html template by using the following code: < link rel="Shortcut Icon" type="image/x-icon" href="../images/favicon.ico" / > (remove spaces in code)

So, one definitely does learn something new everyday. Hat tip to Ali ;)

Tech4Africa 2007: Thanks for the feedback

Technology for Africa Logo

When I first started doing research on the web to get contact details for Southern African businesses & individuals involved with the web and information technology, I wasn’t convinced that there would be massive interest in another technology conference in South Africa.

However, with responses from over 150 people I am pleased to say that I now know that there is a definite ineterest for a conference like “Technolgy for Africa”. We have had some great responses and feedback from interested people and here are some of the suggested topics which will probably be discussed at the conference:

  • Emerging technologies & trends
  • Web 2.0
  • New Marketing
  • The role of Open Source Software
  • Blogging & social/community software
  • Future of the web
  • Telecommunications in Africa - VOIP, mobile/cellular technology
  • Web standards

The “power of the blogosphere” has been a great help in getting the word out there. So far there have been at least 6 posts from different bloggers, all of whom have written very supportive articles. It’s a great help to have your guys support, thanks goes out to:

David Duarte
Cowboysengines
Hash @ Whiteafrican.com
Coda.co.za
Scott.za.net
Muti.co.za

During the next few weeks, our main aims are to find a suitable date, add some new features to the website(technologyforafrica.org.) , talk to the key note speakers - and get as much buy in as possible from the Africa web & technology community…

Watch this space, we are going to make this happen!
