If you are looking for a thematic and original set of social bookmarking icons, here comes an option for you.

Social Lego is a set of 20 icons, built exclusively for WRD readers by Iconshock (same creators of WordPressThemeShock), that has a lego-like texture and includes the items for the most popular social services like Facebook, Twitter, Google+, Youtube and much more.

The set comes as .PNG and .AI vector formats where you can create any size and modify the easily.

It is free to be used in both personal and commercial projects (and can not be redistributed).

P.S. If you share this icon set in your website/blog, please link to this post rather than the download link. Thanks very much for that.

Although listing the contents of a directory is not a good practice for most of the websites (considering the complete structure and files will be available to the public eyes), it is an easy way to show and share files.

The default Apache directory listing/index page is not the most handsome one and h5ai is a template built specifically to improve these pages.

Its is built with HTML5 Boilerplate, jQuery + Modernizr and can be implemented with few steps: "copy folder h5ai to the web-root directory of your server and update the .htaccess file".

There is a list of options provided inside a JavaScript file and, best of all, the output can be presented in multiple languages with the strings being defined inside that JS file.

Similar to the The Wall plugin for MooTools that was shared few days ago, Mosaiqy is a jQuery plugin for presenting images in a Mosaic-like grid interface.

The images are displayed inside randomly moving columns and rows where CSS3 transitions are used for the animations.

Once a thumbnail is clicked, the original version is loaded inside the grid with a nice slideIn/Out effect.

It retrieves images from a JSON/JSONP data source which makes integrating with image hosting services pretty easy and there are already demos for Flickr, Instagram and Panoramio.

Mosaiqy has multiple configuration options like the speed of transitions, delay between each, number of columns/rows, looping on/off and more.

Flashmo, a well-known website sharing free Flash files, has recently released new open source Flash resources.

They are all built with AS3, the galleries have touch support on mobile phones and, besides using them, their sources are a good way of improving skills.

One of them is an mp3 player which can display a playlist and play the items one-by-one or it has a "mini" version which can still play multiple songs but doesn't show the playlist.

The list is fed with an XML file that has the info about the song + artist names and the location of the mp3 file (so, files can be located in different folders).

Another resource is a coverflow-like image slider where you can drag (with touch support) and browse through the items.

Every image can point to different URLs and the database is again an XML file.

And, a 3D spiral gallery which is built with Papervision3D and Tweener.

You can drag up/down or left/right to move around thumbnails, use mouse wheel to zoom in/out, double-click on stage to toggle fullscreen.

For a complete customization, settings can be edited from an XML file.

There are also other new resources like 3D curve gallery or 3D touch ring.

Resources on creating CSS3 buttons that looked stylish was shared previously at WRD.

CSS3 Buttonize Framework is a new addition to this list which comes with styles for creating buttons in various sizes.

Icons can be used inside the items and there are ready-to-use classes for building disabled, striped or highlighted buttons and a panel/horizontal navigation.

PCSS is a PHP(5) library that allows us to write CSS(3) code with a simpler + shorter syntax and brings awesome features like server-side browser specifics, class nesting, default unit and variables.

As the CSS is preprocessed on the server-side, every designer's dream: "dynamic CSS" comes true and variables can be used easily.

The rules being processed on the server-side also helps avoiding redundant commands (like many "-webkit", "-moz", etc.) as only the rules needed for the browser will be generated.

Using the library, we can set a default image directory and default unit (em or px) to prevent rewriting them again and again.

There are also shortcuts provided for @font-face usage and nesting of CSS rules.

There are various new and exciting stuff with the website development like HTML5 and CSS3.

But, when it comes to designing HTML e-mails, it is still the tables and hacks for improving compatibility with different e-mail clients.

HTML E-mail Boilerplate is a project which presents a starting point for HTML e-mail design and includes solutions for the major rendering problems with the most common email clients.

The code is very well documented and the download pack includes a non-documented version).

InstantShift, a popular blog on web design and development, is sharing a set of 40+ good looking icons.

The icons are simple-yet-beautiful, have a chic texture over them + come in 2 formats:

• .PNG – which are sized 32x32px
• .PSD – which are layered and can be resized as you wish

P.S. They are free to use in both personal and commercial projects.

Awkward Showcase is a very flexible jQuery content slider plugin that can display any type of HTML content.

The plugin only controls the functionality and design is completely created on the HTML-CSS side.

Slider can have thumbnails that are positioned vertically or horizontally, captions can be displayed for each item and multiple tooltips can be positioned over slides (to provide detailed info about a specific part of the slide).

It can auto-arrange the height according to the content displayed, has multiple transition effects, the interval between each slide can be changed and much more.

We all know robots.txt, the text file that is uploaded to the root folder of websites and helps us communicate with the search engine bots for telling them which pages to not to index.

What if we want to communicate with humans and tell them who built the website? There is usually not a suitable space for this in websites and visitors may not be interested in seeing such an information inside "about" pages (in most cases).

This is where Humans.txt, which is an initiative for knowing the people behind a website, comes in.

Just like robots.txt, you upload a humans.txt file to the root folder of the website and can mention every detail that "careful eyes" would be interested in learning about the team behind, the designers, developers, copywriters, etc.

It won't be wrong to expect it getting popular as some big guys like Google or Flickr already have it. And, WRD has it too : ).
