Today we are fortunate to have a guest post by Patrick Lightbody, most recently of BrowserMob fame (and previously Selenium work, OpenQA, WebWork, and more). Let’s listen in to him talk to us about load testing, and let him know your thoughts in the comments below:

I’ve been developing and testing complex [...]

How about if all you needed to do was:
PLAIN TEXT
JAVASCRIPT:

var server = new Addressable.Server({ useGears: true });

server.onmessage = function (message) {

        log(message)

}

server.connect(function (id, url) {

    log(”Connected. Messages will appear here.”)

    $(”#clientId”).html(”Client-Url: “+url)

    $(”#testForm”).attr(”action”, url)

Jeremiah Grossman, our number one Web security chap, has some interesting words as we jump into 2009:

It’s unanimous. Web application security is the #1 avenue of attack according to basically every industry data security report available (IBM, Websense, Sophos, MessageLabs, Cisco, APWG, MITRE, Symantec, Trend Micro, SecureWorks, ScanSafe, IC3). This is in addition to reports [...]

Steve Souders has detailed the coupling of script loading with various asynchronous techniques with examples that show the timings that you can get. First he sets the scene:

One issue with async script loading is dealing with inline scripts that use symbols defined in the external script. If the external script is loading asynchronously without thought [...]

The demo above is tyPhoGraphic a declarative CSS transformation library.
If you check out a demo with a browser that supports the CSS declarations, you can see that the work is done via:
