New Video – BlueMix – Using NodeRED to Retweet specific topics

Although this could be considered “cheating” in the social world and I certainly do not condone automated social behavior, I do think NodeRED on BlueMix is very cool and easy to use and this is a fast, simple, and effective way to promote a given topic on Twitter.

What I did was create a flow in NodeRED to look for any Tweets that mention “bluemix” and the retweet that tweet to help promote BlueMix on Twitter. Here is the flow on BlueMix:NodeRED Flow

Check out my video below to see what each element in the flow does and how the application works. You can sign up on on the Codename: BlueMix beta today here to give this a try.

pillar_buy = $('#screen_pillar_buy').prop( "checked");

Setting is just as easy:

$('#screen_pillar_buy').prop( "checked", pillar_buy );

Properly cleaning up a JQuery Dialog box to prevent memory leaks

One of the cool things about JQuery is you can declare an invisible DIV with a “display:none” style and then use that DIV as the content for a popup dialog box in your application. I have been working on a pretty dynamic web application that is pretty much all JavaScript and buttons come and go based on the users actions. This can present a problem with regard to memory consumption. Each time you call $(“#dialog”).dialog() jQuery creates a set of DIV’s in the base of the HTML.
