Today the Scotch on the Rocks Speakers list was release by Andy Allan and his motley crew.

I'm sorry to say that I've been putting this post off. Why? Well to be honest I've been struggling with getting my head around how to actually use longpolling. Its all very well understanding the mechanics, but how can you use it effectively.

Part of the problem I've been having is the nature of sending messages and filtering them with BlazeDS. What I keep forgetting is that long poll messaging is "fire and forget". You don't send a message and expect an immediate response. You send a message and a response might be broadcast to all event listeners with a specific filter. If you want a request and response, call a webservice or a make an ajax request. Don't use long polling and event gateways.

I'm rubbish! I really am... I promise and I promise to keep on top of Blog Round-ups, but I never seem to quite manage it.

I would really like to keep writing this round-ups ever week, but its quite an effort. Can I persuade anyone to co-author these posts with me? Leave me a comment. Drop me an email. Shout me on Twitter.

Anyway, on with the round-up.

Ten days ago I post my first project to RIAForge. Its a pretty simple project as it only consists of one CFC and I would appreciate some feed back on the code. Hence the request for a code review.

This CFC is based on research and work that I did to be able to create a finance calculator for a client and works quite nicely. I'm also pleased to see that at the time of writing this post my project has already been viewed 700 times and downloaded 23 times. I hope you're finding it useful.

The CFC is, as the title of this blog post suggests an APR and IRR calculator and you can download it from RIAForge here : http://aprcfc.riaforge.org/.

I've spent some of my week this week fighting with JavaScript, BlazeDS and ColdFusion to get a working model for some ExtJS functionality that I'm currently building at work.

One of several pieces of functionality we'd like is to have is real time notifications of workflow changes. The way it was described was "we want to push alerts to the users".

I decided to have a look at how we actually addressed this "problem". We didn't really need to "push" alerts to users, so the solution was traditional polling or long polling.

To kick start my reading of blogs I've started listening to podcasts again.

I used to listen to ColdFusion Podcast and Weekly, but unfortunately they are now deceased, so I had a bit of a search and asked around on Twitter. Here's the podcasts I'm now listening to and a few thoughts.

This blog round up is somewhat later than I had intended, but for good reason.  I've been waiting for a couple of blog posts to emerge into the public domain, so that I could include them in the round up. I can't impress upon you how important it is to read these posts.

Sorry..... Its been a very very long time since I posted a blog round up. 

I recently moved my blog from hosting on my PC at home to extremely cheap Coldfusion 8 hosting with Hosting A to Z and I've updated to MangoBlog 1.4 with a new site theme, so I've decided its time I got my act together and started posting again.

I mentioned on Twitter that I did a crash course in using Twitter for some of my colleagues. They needed to know how it could be used for networking and marketing. I was asked what my thoughts on marketing using Twitter were. I said I would write something up and get it posted.
