Kevin Werblog says Voice over IP coupled with Wi-Fi is the killer app: David Sifry's blog pointed me to Kevin's post. David expands on Kevin's point by expanding the notion to public spaces. There are products that do PBX-based VOIP with any Wi-Fi network from SpectraLink and now Vocera. But the real issue in public spaces is authentication and billing: how do you handle a captive portal login from a telephone or badge interface? Obviously, you partner with aggregators to integrate authentication in the phone through corporate IT configuring systems. Boingo + VOIP = VOIPo? [80211b News]
I remember reading somewhere that 80% of a telco's infrastructure cost is for billing purposes. So, you could roll out a network that charges 25% of current systems, say on some form of subscription purpose, and still have higher profit margins than telcos. Oh, and the new system will foster innovation. Thus killing the old telcos just that little bit quicker.

Self-Playing Media with Java Media Framework. The Java Media Framework may not impress you as a media player client, but when you realize that you can deploy content without requiring a specific player on the user's machine, and that you can bundle the player and the media in a single download, it starts to look very interesting. [O'Reilly Network Articles]
Hmmm. A double clickable moofie. The obvious thing to do here is to include some naive encoding of the included datastream. But, do remember to munch the java byte codes or JAD will undo all your hard work ...

OFBiz Turning OO on its Head or Programming in the Large?
My take on all this is that "programming in the large" is a bit different that the usual programming. What happens is that abstractions that are quite similar to the usual procedural things become important. You simply can't deny the importance of these Actions in webapp or gui work, however they aren't the same thing as functions in C. The difference is that an Action (aka Command) can be persisted, sent as a message, suspended, undone, redone, stopped, cancelled, approved etc. These are not attributes that are associated with function in the procedural sense.
[::Manageability::]
Hmmmm. This is all starting to feel a hell of a lot like python crossed with scheme. I mean, we have taken a strongly typed language and side-steped all of the strictures of typing.
I'm not saying this is necessarily a bad thing. I love programming in python where typing is a run time thing, and coding is so quick. I'm just wondering why we are doing this Java? So we can be J2EE buzzword compliant?

3G Burdens Threaten Carriers. Third-generation mobile networks, hailed as a source of revenue beyond imagination just two years ago, have become a millstone around the necks of many carriers worldwide. Financial migraines and technology-development crises aside, participants at the UMTS Mobile Internet Conference here this week are beginning to voice the unthinkable: that there is no compelling reason today for customers to gravitate toward 3G. [Smart Mobs]
People used to joke about buying the weather guys a window, but whether prediction is hyper-accurate in comparison to the telco's understanding of the common phone user.

Prolog and Natural-Language Analysis. From the introduction to the book:
This book is an introduction to elementary computational linguistics from the point of view of logic programming. The connection between computational linguistics and logic programming has both formal and utilitarian aspects. On the formal side, we shall explore the restricted logical language of definite clauses as a means of expressing linguistic analyses and representations. On the utilitarian side, we shall introduce the logic-programming language Prolog, whose backbone is the definite-clause formalism, as a tool for implementing the basic components of natural-language-processing systems.
Now available online.
(The idea of parsing as deduction has been mentioned here before.) [Lambda the Ultimate]
This is especially for a friend of mine who was grousing the other day about how he wanted to use SWI Prolog to data munching. :-)

EJB best practices: Entity bean protection. Level: Intermediate
How do you enable users to access your application data without directly exposing your entity beans to the Web tier, which could open your application to security threats? Brett McLaughlin offers a solution that is safe for your entity beans and efficient for your overall application. [IBM Developer Works - Java Articles]
Something else for me to read.

Petri Nets (awareness). petridish: the petri net framework is yet-another BobProject(tm). I'd originally planned on building werkflow using blissed, which is a finite-state-machine framework. But, then, a few folks chatted with me about Petri nets, and I did a lot of reading from CiteSeer. I have decided that yes, Petri nets are indeed the way to go. Hence, the new project. No release yet, but just trying to raise awareness, since workflow seems to be a somewhat hot meme these days.... [bob mcwhirter]
Bob, feel free to post your refs on petri nets. They are something I have been trying to grok for a little while now.

XML is Not A Programming Language. From Joe's Jelly:
Booo. XML is designed for representing data. Programming languages are designed for representing behavior. Have a look at the examples of oXML and try writing them out again in a dynamic OO language like Python or Ruby. The XML versions are massively overcomplicated and very hard to read (XML has a noisy syntax). Remember, machines have no problems reading code, it's humans you need to think about.
I can not agree with this enough. XML is a great language for structured data, terrible for programming anything more complicated than a simple series of instructions (à la ant). This is also one of the many reasons I detest XSLT. [The Fishbowl]
Can i say that XML is a great structured format for structured data. Great rant. Reminds me of many stories that should only be told over beer.

 Documentation Enhancer for Java.
[Erik's Weblog]
Hmmm. Tasty. I wonder how long it would take to redo this using BCEL. And then to automagically paste it back into the java source files. Hmmm. *duck*

Jamming camcorders in movie theaters. Former Divx engineers are developing a technology that could thwart low-tech movie pirates who use camcorders in theaters. [CNET News.com]
There is nothing that a large corporate can protct that some drunk engineers can't crack. Honestly.

Beer O'Clock. It is 6pm on a Wednesday. It is time to stop thinking about Websphere. I am now going to go to the Sporters' Bar under the Menzies Hotel, where I will play pool and drink beer. [The Fishbowl]
If there is one bitch I have with not reading blogs at work anymore, this is one of them. D'uh.

[Java-Channel]
I've wanted one of these things for ages... [James Strachan's Radio Weblog] [Steve's Radio Weblog]
Hmmm. exe4j + swt => ?

Open Source? Public Source?. Is ZOE really Open Source? [...] [Be Blogging]
An interesting GNU Rant on what is wrong with the APSL, from which the ZOE license is derived. According to the FAQ anyways. In short, don't go there Jim.

No longer caring about where my data is, but simply what its about. [Pushing the envelope]
I, too, am heading in that direction. But I need so much more than just email and blogs. I need the ability to highlight chunks of webpages, and keep them for later with full referencing, I need the ability to scan the newsfeeds (yes there is still some signal in the noise). The person who pulls together an information management platform that does all the above, and reminds me to bring home flowers for my ever forgivful better half, will win my undying love.
