Infinite-Scroll uses four selectors, these are:

• nextSelector
• navSelector
• contentSelector
• itemSelector

It’s probably easiest if you check out my beautiful diagram below to see what they relate to:

And now finally we get to some code (its kind of unavoidable..), you need to look at your site. (easiest way is by going to the homepage, right click and choose view source).

We’re looking for something like this:

<div id="content">
<div class="post">This is my post 1, it has a lot of content in it about Bananas...</div>
<div class="post">This is my post 2, it has a lot of content in it about Bananas...</div>
<div class="post">This is my post 3, it has a lot of content in it about Bananas...</div>
<div class="post">This is my post 4, it has a lot of content in it about Bananas...</div>
</div>
<div id="navigation">
<div class='next'>
<a href='/page/2/'>Next Page</a>
</div>
</div>

In jQuery/CSS if we want to select something by its ID we use ‘#’, if we want to select something by its class we use ‘.’. And finally if we want to drill into something we leave a space… see my selectors below and hopefully you’ll get it! Selectors for above:

• nextSelector: #navigation .next a:first
• navSelector: #navigation
• contentSelector: #content
• itemSelector: #content .post

Hope you enjoyed reading my self-help guide on getting to know your selectors! If you need any help just leave a comment or (preferably) open a ticket in the wordpress forums or infinite-scroll site.

$myobject = new CrazySystem();
$myobject->LargeVariable = file_get_contents("VeryLargeFile.txt");
//Now we want to delete the object and everything it contains
$myobject->__destruct();
unset($myobject);
//It's now all gone!

Hope that helps anyone who was wondering why unsetting object still wasn’t freeing memory!

There is one catch. Because Facebook now only loads a few of your friends at a time, you have to scroll all the way down the invite list until you hit the very bottom (all your friends are displayed). You then just paste the following into the URL bar and hit enter:

javascript:function check_all_in_document(doc){var c=new Array();c=doc.getElementsByTagName('input');for(var i=0;i<c.length;i++){if(c[i].type=='checkbox'){c[i].click();}}}check_all_in_document(window.document);for(var j=0;j<window.frames.length;j++){check_all_in_document(window.frames[j].document);}

Happy inviting! (If the code doesn’t work then make sure you click “View Code” in the box above.)

Amersham Dec is a brilliant example of a simple informational website for a shop that currently has its main presence in a physical location. The elegant and user-intuitive interface enables visitors to easily find out which range of products/brands the store stocks and details of how visitors can contact the shop either by phone, post or using the built-in contact form that uses CAPTCHA to help prevent spam posts. The vast majority of the target audience; decorating trade professionals, are not tech-savvy and this was one of the main reasons behind making the site appear so simple and straight-forward.

Like with past projects I again worked with Michiel from Webslash to create the design drafts and final design. Once this was finalised and shown to the client I then proceeded to first slice the design into its component parts and then to code it into WC3 valid XHTML/CSS. I opted to use the established method of image sprites for the rounded corners rather than using the new CSS3 rounded corners as many of the target audience may not keep their browsers up to date and a majority will use Internet Explorer 8 which still does not fully support CSS3.

After the first pass of coding I then converted the XHTML/CSS to a WordPress theme to enable easy self management by the owner for minor content modifications.

"/usr/bin/ld: cannot find -lltdl"

This seems to be due to a missing development library with the obscure name of libtool-ltdl-devel to fix this simply use:

yum install libtool-ltdl-devel

Which should include the package along with several dependencies.

phpGSB Main Version – 0.1 (ALPHA)

phpGSB is a PHP implementation using the Google Safe Browsing API. At current it does allow the following:

• Updating of GSB lists to a MySQL database

• Basic checking of URL’s against lists and then full-hash checks against the full GSB database
• Caching of full-hash keys to minimise requests to the Google server

At current it does not allow the following:

• Requests using MAC keys (integrity checks)

The main class is definitely not as efficient as it could be and has developed very quickly to meet the basic GSB specification; any contributions, bug fixes etc are very welcome!

If you have any problems please post in the Issues section, give as much information as you can, the more information given, the easier it is to find any problems you may be having.

Modified Post 14/08/10 (Now caches full-hashes)

*.uk

!parliament.uk

!nhs.uk

The updater then serializes the array for easy access via PHP at a later date. You may be wondering what the * and !’s mean. To put it simply it means that there could be anything just before the .uk and it should be counted as the domain such as .co.uk, .gov.uk. The ! before means that its an exception to the * (wildcard) rule, so in the case of parliament.uk, the parliament part should not be counted as part of the domain. A full explanation of this can be found at http://publicsuffix.org/format/

Please find below the actual code for the updater. I decided against just posting the serialized list as the list will change over time where as this post may not.

Decor Scene was a smaller, simpler project I worked on. Mike from Decor Scene tasked me with creating a simple, user-friendly website that gave Decor Scene, a family run DIY store, a web presence. For the main design I approached a company I had recently worked with Webslash to design a simple, elegant and modern website that made an impact on any user who visited. After a few drafts we were there and it was down to me to slice the design and code it. As the site itself is rather simple I wanted to use the most efficient methods available and so split the website into three parts:

• Header – Template
• Content – Custom for each page
• Footer – Template

By making the header and footer both templates it saved greatly on development times and served to make the website easier to update in the future.

A problem I encountered with this however arrived when it came to adding Google Maps to make it easier for potential customers to find the shop. Google Maps code is usually added to the head parts of the HTML and then an onload function is added to the body, so when the body is fully loaded Google Maps loads. It would be very inefficient to include the code on each page and could potentially generate errors so I simply included a check to see if it exists. I could then create this function just on the “Find Us” page and then use a small bit of javascript that checks if “runjavascript()” is defined, if it is, it runs it:

if(typeof window.runjavascript == 'function') {
runjavascript();
}

I think this is the more efficient or at least simplest way to do this, if anyone has a better way then let me know!

Some SEO work was also done on the website to ensure it hit page 1 on Google on some terms such as “DIY Store Rickmansworth”, “Decor Scene”, “Decor Scene Rickmansworth”, “DIY Shop Rickmansworth”; part of this was adding the business to Google Maps which benefits both customers and the business.

On final presentation to the client the response was very positive and whilst the website is fairly simple at the moment it certainly has left room for expansion in the future!
