Railo And AOP Transactions

By barneyb on July 23, 2010

If you're reading this, chances are good you're a software developer.  And that means you never touch the DB outside a transaction, right?  Of course, right.
Most of the time, transactions are a bit of a bear because their use is orthagonal to your business tasks.  To put that another way, business operations flow vertically from [...]

Tokenless location() Without Parameters

By barneyb on July 8, 2010

Both Railo and ColdFusion have added a builtin 'location' function in recent versions, and like their CFLOCATION counterpart, the default behaviour is to append the jsessionid/CFIDE/CFTOKEN tuple to the URL when redirecting.  I find this rather annoying, and it's even worse since FB3lite has a 'location' function which defaults it to false.  Unfortunately there isn't [...]

Amazon S3 CFC Update – Now With Listings!

By barneyb on June 8, 2010

I've added two new methods to my Amazon S3 CFC: listBuckets and listObjects.  Both of them do about what you'd expect, returning a CFDIRECTORY-esque recordset object containing the rows you are interested in.  I've attempted to make S3 appear like a "normal" filesystem where "/" is S3 itself, the top-level directories are your buckets, and [...]

Groovy Gravity Processing

Groovy Gravity Processing

By barneyb on May 28, 2010

Joshua (a coworker) and I have been talking about gravity simulation for a while, and this week I threw together a very simple model to do exactly that.  This grew out of a game called Flotilla that he came across somewhere and has been working with the developer to add a network multiplayer mode.  Flotilla, [...]

Tulsa CFUG Presentation (CFGroovy)

By barneyb on May 26, 2010

Yesterday I presented CFGroovy to the Tulsa CFUG via Connect.  The recording is now available on Connect, thanks to Steve.  You can also grab the slidedeck (as a PDF) I skimmed through, and of course, the CFGroovy framework itself (project page, core SVN, demo SVN), including the demo files that I showed.  Note that the [...]

Groovy DataSources for Railo

By barneyb on May 25, 2010

If you've ever wanted to do raw JDBC stuff in your ColdFusion applications, you probably know that you can get a javax.sql.DataSource via this code:
createObject("java", "coldfusion.server.ServiceFactory")
.dataSourceService.getDatasource("myDSN")
Unfortunately, this doesn't work on Railo, because the result isn't actually a javax.sql.DataSource, it just looks like one (see RAILO-43).  To put that another way, it's duck typed.
Fortunately, [...]

CFGroovy at the Tulsa CFUG on May 25th

By barneyb on May 18, 2010

Next Tuesday (May 25th), I will be presenting CFGroovy to the Tulsa CFUG via Connect.  Details are at http://www.tulsacfug.org/meetings.cfm, but the important bit is that it's at 12:30 central time, not in the evening.  Steve Bryant – who manages the group – graciously extended a general invitation to anyone else who would like to join [...]

Do You Know These Shoes?

Do You Know These Shoes?

By barneyb on May 17, 2010

If you can identify this pair of shoes, I'll buy you a drink of your choice next time we meet.  If you're wearing a pair of them, I'll buy you two.

GalConvict

By barneyb on May 17, 2010

This morning, in response to my Processing and Galcon post, I received this email:
Hey,
Stumbled across your article about using processing :)  Sounds neat!
Anyway, I don't like having to make these requests – but because of how
trademark stuff works I have to request that you change the name of your
project to something that doesn't contain the [...]

Processing and Galcon

Processing and Galcon

By barneyb on May 14, 2010

I did a little experiment last night using Processing, which is a Java-based visual programming environment that I've repeatedly run into in various different contexts, but had never really done anything with.  I've become completely addicted to Galcon Lite on my iPhone, and figured it was a "sample" to build with Processing.  Note that I [...]
