HL7 FHIR Aggregation

Really good explanations recently on Grahame Grieve's weblog recently describing HL7 FHIR (Fast Healthcare Interoperability Resources) from the perspective of v2, CDA and v3 implementation.


FHIR for v3 and CDA implementers
FHIR for v2 implementers

One thing I am still trying to understand is the issue of aggregation, which is accomplished using Atom feeds, which in itself makes a lot of sense, and may have all sorts of side benefits, though it is a little frustrating if your browser (ie Opera) tries to handle the aggregation as though it were a blog feed... but there are two kinds of aggregation we must consider here one when we aggregate a number of like resources, for instance as the result of a non-deterministic search, and the other when multiple types of resource are aggregation into a Message (for v3) or Document (for CDA) Resource.

I find this confusing because it appears that position is used within the Atom syndication to determine which Resource to use as the transport wrapper. Still trying to wrap my head around this. Should prove to get interesting very quickly.

Mobile JavaScript Hybridization

Pros: Well-written, Easy to understand

Best Uses: Intermediate

Describe Yourself: Developer

I have just finished reading a review copy of Adrian Kosmaczewski's book on Mobile Development using JavaScript, and I highly recommend it, particularly if you are faced with a decision about mobile development frameworks and you have a team which is already familiar with hybridized JavaScript approaches like JQuery or GWT.

After dealing with some basic groundwork, Kosmaczewski devotes a solid chapter to each of the prevailing uses of JavaScript in the mobile arena: HTML5 with JavaScript, JQuery Mobile, Sencha Touch, and PhoneGap. While there are advantages to all of these approaches, the prevailing wind seems to indicate use of JQuery Mobile if you are already invested in JQuery, and Sencha Touch if you are building an enterprise-size solution.

Either of these approaches - actually, all of these approaches - will allow you to deploy to multiple platforms, which is a key component of JavaScript hybridization: ubiquity. The difficulty I have personally encountered is the flip side of the ubiquity coin, flexibility. JavaScript may be everywhere, but can also become everything, and this can lead to paralysis.

An example of this: I have recently been working on some development in with mobile SVG, which is becoming more and better supported on various mobile platforms. SVG is not hard to work with, and rolling your own application to do exciting things is enjoyable if you like that sort of thing; however... do you use HTML with embedded SVG? HTML5? Just SVG with E4X/EcmaScript (which is just JavaScript, really)? or Raphael.js, or Sencha Touch, which encapsulates it?

At some point, you just need to stick your paddle in the water and see which way the current takes you. And Kosmaczewski's book is a good starting point.

Promoting health? It's all in the game | ...

I really want to see this sort of technology succeed, in part because it demonstrates so much the principle of  "genius of the and" - gamification of health not involves the patient more with his own diagnosis and care, it can also provide his healthcare team with better, more regular check in points, as well as an access point for delivery of timely information. For healthcare to be successful, it needs to follow a pattern like this. Okay, I'm a techie, and I can't help thinking on that level... this approach to delivery of information follows an, albeit loose, Model View Control (MVC) pattern - identifying what information is required to trace healthcare needs, then coordinating between patients' and practitioners' ability to view this information and respond to it, and formalizing a channel of communication between patient and practitioner, outside office hours.

3,001 THINGS YOU DIDN'T KNOW!!!

I firmly believe that most internet memes are quite silly, but the bit about Windows and "Con" is kind of spooky.

3,001 THINGS YOU DIDN'T KNOW!!! - 1) The moon smells like gunpowder. 2) The creator of the Nike Swoosh symbol (Caroline Davidson) was paid only $35 for the design. 3) You can't create a folder called "Con" in Microsoft Windows. 4) The formula for Coca-Cola has never been patented. 5) Al Capone once said, I am like any other man, all I do is supply a demand. 6) There are five states in United States with no sales tax.

Siri and Wolfram Alpha

I don't use Siri, and it really goes against my nature... I have a screen in front of me all day, so why add impedance mismatch through speech? What Wolfram Alpha offers, though, is the ability to share mathematical proof through a URL, and to a math geek, that's pretty cool.

Neat. Mindwheel port for Windows posted by developer

Neat. Mindwheel was an impressive interactive fiction created by Synapse/Broderbund back in 1984, authored by former Poet Laureate Robert Pinsky. I am currently reading Pinsky's translation of Dante's Inferno, and it is interesting how lyrical, and yet claustrophobic and in places even creepy Mindwheel can be, much like Pinsky's Inferno. This download is a Windows port, and what's really cool is it has been made available by Steve Hales, the lead developer for the project, and apparently also designed the audio sub-system in the ultra cool T-Mobile SideKick. From his about page: "If anyone remembers: Fort Apocalypse , Slime, Dimension X, I coded and designed them with Ihor Wolosenko. I also coded and co-designed Mindwheel with Robert Pinksy, the famed poet and author. Working with Robert changed the way I read and write words forever. He was writing History of my Heart during the development of Mindwheel, so they have familiar themes. You can even get a deeper meaning behind Mindwheel, by reading this book. Although, he claims, they are not connected." Cool. Mindwheel | Igor's Software Laboratories Created in 1983, 1984. This was a mind blowing experience. My first experience with many computer science concepts that are commonplace now. Object oriented programming, Virtual Machines, AI, language...

Hot processing!

Great story from Ken Holman, quoted for coolness and also for #refrigerator... Hot processing! So I'm standing here at my desk preparing my UBL 2.1 PRD3 D1 package and I have two very long XSLT transformations to run. One takes 98 minutes and the other takes 124 minutes, running in Java in BSD on my Unibody MacBook 2.66GHz I7 (dual core; quad process). Input file 10Mb; output files total 183Mb. I used to run these two tasks sequentially, but I today checked out "Activity Monitor" and discovered that while each transformation starts off using about 250% CPU time (sharing processors while building the memory structures), they quickly become single processor 100% (±2%) only (while traversing the memory structures). So I decided to run them simultaneously instead of sequentially, saving me (theoretically) close to 98 minutes since most of the time appears to be at 100% and when they are both running Activity Monitor says they are both running at 100%. So far so good ... but within minutes the fans on my machine get too noisy to talk over! I check the status bar and, sure enough, both fans are running >6000rpm. My fans so very rarely make any noise, so this is very noticeable and annoying. My very wise wife suggests I go to the kitchen and get the flat-bottomed aluminum frying pan to place under my machine, upside down so the flat part of the pan is full on the bottom of the Mac. Maybe two minutes later the fans are running <4000rpm and we can talk without raising my voice over the fan. Well, now as I'm typing this Google+ post the frying pan is getting hot! The fans are up to 4800rpm again and slowly rising. So, I've just gone to the kitchen, brought out a second aluminum frying pan, put that one under the Mac, and put the first frying pan into the refrigerator to cool down for the next swap. Within a minute the fan is back down <4000rpm. My review and editing of the above takes five or 10 minutes. Already this pan is heating up as it isn't as substantial as the first pan ... fan speed up to 4400rpm ... but the first pan will be cold by the time I need to swap again. Such a simple improvement! Wish I'd thought of it. View or comment on Piers Hollott's post »

Tim Bray on dynamic typing, Android, Java

See, this is why I respect Tim Bray's opinions so much; because he is a tireless member of my post-SGML/functional programming tribe. For instance, see this post on static vs. dynamic typing, and why it's not such a big deal with mobile Java for Android. I particularly like this comment, though: "From: Tim Converse (Dec 29 2011, at 10:32) "The Java language in particular suffers from excessive ceremony and boilerplate. Also it lacks important constructs such as closures, first-class functions, and functional-programming support." This is a very concise version of the case for Scala over Java." Bingo. ongoing by Tim Bray · Type-System Criteria Starting some time around 2005, under the influence of Perl, Python, Erlang, and Ruby, I became convinced that application programs should be written in dynamically-typed languages.

Embassytown

Embassytown by China Miéville
My rating: 5 of 5 stars

"Embassytown is a fully achieved work of art." High praise from Ursula LeGuin (in her Guardian review), one of the writers who have really driven the potential for Science Fiction as artform. Best book I have read so far this year, for what that's worth, Embassytown is a maverick read, setting out a subtle but profound agenda, and then carrying it through to a stunning conclusion, much like Suzette Haden-Elgin's Native Tongue or Anthony Burgess's Clockwork Orange. If you have read it already, read the first few chapters again - it's amazing the detail employed to carefully inch the story forward, play it backward, then when all the pieces are in place, unleash it.

Miéville is known for his disapproval of the high fantasy genre, and this is the complete opposite of that, dealing with language not as a way of identifying class and race, but undermining this notion, as in the works of Burgess, Burroughs or Lessing, demonstrating how language creates class, language creates race, language creates culture, and then, going on to demonstrate, quite graphically, how language is also, to quote Burroughs, "a virus sent from space" - a destructive addiction.

China Miéville has always been a deep and deeply intelligent writer. Embassytown shows that he is, simply, a great writer who should not be ignored.

Cool technology of the week...

Pretty amazing... the Lytro is coming out next april, at a 400-500$ price tag.... It is a "light-field" camera, which means basically the camera takes in all light which falls within its field, and you can focus the picture after you have taken it. Depth of field is digitally constructed. Of course, one result of this is that your picture files are very dense and very large. The form factor is based on the optics required, but also looks nice. Lytro: The Biggest Thing to Happen to Photography Since Digital The Lytro is the world's first consumer light-field camera. Here's the backstory of how it's made and why it's so different from other cameras on the shelf.

Tuesday+

Several years ago, an acquaintance of mine started a project called "Topic Tag Tuesday". This was back when we were both spending more time on Twitter, and it was great entertainment. In order to hone my own writing, I would like to do something similar on Google+ to see if the entertainment value still holds up.

I am curious if the a Google+ Circle will lend itself to this sort of project, so I'm creating a new Circle, called Story ("Story Circle," see?). On Tuesdays, I'll post a blurb in the Public stream asking for topics. Comment on the blurb with a topic, and I'll add you to my Story Circle. Later that day, I'll write a short story incorporating one of the topics and post it back to the Story Circle, completing the loop.

If you're interested in this idea, follow me on Google+.

Quoted for #refrigerator... this xkcd comic is truly a masterstroke of overdetermination.

Waking the Moon by Elizabeth Hand
My rating: 5 of 5 stars

Rereading this book... read it when it was first out in the early nineties after loving Hand's earlier Winterlong trilogy. Didn't like this as much at the time because it couldn't compete with the overabundance of wow that were Liz Hand's science fiction - including Mars Hill, I suppose.

In retrospect: I have two favorite writers, Liz Hand and Guy Kay. Kay's novel Tigana features this crazy Benandanti vignette based on Carlo Ginzburg's historical writing in Night Battles, and the Benandanti in Waking the Moon offer a great companion to this. If I was going to recommend a first book to read by Hand, I would suggest Glimmering or Mortal Love because both of these are steeped in wow. Or Winterlong, which still ranks in my 5 or so favorite books.

Grahame Grieve on National Projects and Standards

From his Health Intersections site, this is Grahame Grieve on National Projects and Standards, and the tension between the two. I'm a standards geek, and I live for this sort of discussion. In this very concise article, Grieve discusses why projects at the national level rely on international standards groups, and how this introduces stress factors into these projects. I also appreciate Lloyd McKenzie's comment about the interoperability across borders. This is one of the promises of using international standards, but in reality, it rarely comes up, and comes with it's own host of issues. Interoperability between two sibling releases of a standard can be trying enough, let alone between two nations localization to the same standard. But that is what makes the work exciting.
