However, it turns out that my browsing experience is unusually slow at this moment. Eventually I realized it is because I have my FireBug turned on due to my earlier little project. After I disabled FireBug, web browsing resumed its normal performance.
A few hours later when I tried to run my little application again, it surprisingly failed on FireFox. The app loads into FireFox, but it does not respond to any user interaction. It is not frozon or dead, as I can still type into text fields. It looks fine too as the UI is still rendered correctly. But it is just not responding to any event such as "submit" or "click". On IE, the application is still working fine. The only thing that's changed is that I have FireBug disabled now. Would disabling FireBug break my app? Hard to imagine. Nevertheless, I re-enabled FireBug. Surprisingly the application is working again. If I disable FireBug, the application stops working. So does disabling FireBug actually break my application?
What does the error message mean? Where does the error come from?
Well, now enters a four-hour exciting debugging session....
if (window.XMLHttpRequest) req = new XMLHttpRequest();
else if (window.ActiveXObject)
req = new ActiveXObject((navigator.userAgent.toLowerCase().indexOf('msie 5') != -1) ? "Microsoft.XMLHTTP" : "Msxml2.XMLHTTP");
req.open("GET", url, false);
The problem is the "req.send()" statement. When you call "send()" method for an XHR object, FireFox expects an argument for this method, even if it is "null". Without an argument, FireFox throws the above exception. Once I changed "req.send();" to "req.send(null);", the problem went away.
Can the message be any more esoteric?

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happe...

The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from ha...

The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series dat...
