User Experience quotes and articles to inspire and connect the UX community | inspireUX from __future__ import * The browser security model dictates that XMLHttpRequest, frames, etc. must have the same domain in order to communicate. That's not a terrible idea, for security reasons, but it sure does make distributed (service oriented, mash-up, whatever it's called this week) web development suck. There are traditionally three solutions to solving this problem. Local proxy: Needs infrastructure (can't run a serverless client) and you get double-taxed on bandwidth and latency (remote - proxy - client). Flash: Remote host needs to deploy a crossdomain.xml file, Flash is relatively proprietary and opaque to use, requires learning a one-off moving target programming langage. Script tag: Difficult to know when the content is available, no standard methodology, can be considered a "security risk". I'm proposing a new technology agnostic standard methodology for the script tag method for cross-domain data fetching: JSON with Padding, or simply JSONP. Let's take the del.icio.us JSON API as an example.
25 great free UX tools There might be no such thing as a free lunch but thanks to the wonders of Open Source software, freeware and trial software there most certainly is such a thing as free software. In this article I list 25 great free UX tools, including tools to help with prototyping, annotating, screen grabbing, site mapping, usability testing, accessibility and analytics. Prototyping tools Pencil Pencil is a nice little Open Source tool for creating prototypes, UI mockups, and UX diagrams, such as user journeys. Pencil – A free prototyping and diagramming tool LucidChart LucidChart is an online tool for creating diagrams, UI mockups and prototypes. LucidChart – A prototyping and diagramming tool with a free trial version Balsamiq Balsamiq is another online UI prototyping tool and like LucidChart it’s not fee but does allow you to create simple single pages for free using the trial version (just click on the ‘take a tour’ link).

TeleHash / JSON + UDP + DHT = Freedom AJAX / JSON Guide Are you at the stage in your AJAX development where using plain text to transfer your data just is not working anymore? And your fed up with all the <?xml buzz? First off lets create our PHP script that will query the database and then print out the data in JSON format. <? // query $sql = “SELECT * FROM table” $result = mysql_query($sql); while( $row = mysql_fetch_array($result) ) { $first_name = $row['first_name']; $last_name = $row['last_name']; $ajax_data = array(‘first_name’=>$first_name,’last_name’=>$last_name); // encode data into json $json = new Services_JSON(); echo $json->encode($ajaxData); } ? Now that we have the JSON being printed out from the above PHP script we can create our JavaScript to read this data and update the page. <! // now we have access to the properties we put in the array alert(person.first_name); } client.makeRequest(phpscript.php,”); I hope this little tutorial puts the fun back into ajax again. Below is a quick list of useful DOM functions for those new to it:
