Ancient History & Yak Shaving

Leave a reply

From April 2003 until January of 2006, I wrote a blog which was incinerated in May 2011 by a house fire.   This weekend, 2 1/2 years after the fire, I found a backup of the old blog and restored the posts into my current, WordPress-based blog.

The old posts (and this post) are tagged with the category ‘ancient‘.

Below follows a description of the Yak Shaving necessary to restore those posts.  The tale is possibly interesting to someone, in that it includes a working example of using the WordPress XML-RPC API from node.js. Continue reading →

…the hope that Congress will recognize a “moral obligation”…

This article is also cross-posted to my intelink blog.

Part of the Antideficiency Act (codified at 31 U.S.C. § 1342) reads as follows:

An officer or employee of the United States Government or of the District of Columbia government may not accept voluntary services for either government or employ personal services exceeding that authorized by law except for emergencies involving the safety of human life or the protection of property. . . .

I have heard this admonition at various times in the context of Open Source Software: if the government cannot accept “voluntary services”, then presumably it cannot allow people to volunteer to write open-source software for the government. Maybe it can’t even use open source software, since it was either written by volunteers or at least licensed for use voluntarily…?

These concerns are, of course, completely wrong, as I will endeavor to show:

my reverse-proxy

Leave a reply

UPDATE: There is a followup to this post.

Various people have asked me about my reverse proxy server, which I alluded to previously.  I’ve used Apache mod_proxy, and perlbal, but now I do it with a 50-odd SLOC node.js program, which leans heavily on node-http-proxy.  It’s too ad-hoc to be worth posting to GitHub, but its possibly worth describing for any other node.js types out there.

They vs. We

A colleague recently said to me:

There is no “they.”
There is only “we.”

There is no “them.”
There is only “us.”

‘Reverse-Proxy Friendly’

15 Replies

tl;dr: Web apps should work behind reverse-proxy servers out of the box.  Use relative URLs.

As a digression from my usual policy-wonk fare, I’d like to take a short moment to coin a term: “reverse-proxy friendly”.  This is a property of web-applications such that they can be used behind a reverse-proxy server without the need for the proxy server to re-write URLs in HTML.  (And without the for the operator of said application to modify anything about the app.)  The main thing that a web app needs to do (in order to be reverse-proxy friendly) is to use relative URLs, but sometimes there are other changes as well, such as changes to Javascript that computes AJAX or WebSocket endpoints.

Here’s my issue:  Continue reading →

The Dave and Gunnar Show

1 Reply

I had coffee with Gunnar last Friday, and in passing, I congratulated him on his podcast, the Dave and Gunnar Show.  I like his podcast, but in general I noted that my commute is too short to listen to podcasts, and most days I find it’s a little too distracting to listen to a podcast while working.  I have too many childcare responsibilities to listen at home.

Apparently he responded to this by promptly mentioning me and my blog in his podcast, (at the end no less) thus forcing me to listen to the whole thing.   And I note, as fabulous solutions providers, they provided advice on how to listen at 2x speed.

Thanks for the recognition, guys.

Now I’ll have to get the bluetooth adapter for my motorcycle helmet working again.

10 years of Net-Centric Data Strategy

2 Replies

On May 9th, 2013 it will be the 10th anniversary of the issuance of the DoD’s Net-Centric Data Strategy. In honor of this, I would like to highlight a collection of slides that were used (many, many times) to illustrate the concepts of net-centricity, the data strategy, Communities of Interest, and User-Defined Operational Pictures.

These slides are quite dated… last updated in 2006, but there are some great illustrations and concepts that remain relevant.  The Data Strategy was a brilliant work that had great promise for changing the way people see IT in defense, in my opinion. It’s tragic that various personnel changes and other events shifted the focus elsewhere.

VistA, MUMPS and NoSQL

24 Replies

[Extra disclaimer: I am not currently involved in any deliberations with regard to AHLTA or VistA or iEHR, and have no particular knowledge of current thinking on EHR inside the Pentagon. I briefed the Hon. Beth McGrath on Open Source Software in April 2011 – a long time ago.]

As some of you probably know, Jon Stewart of the Daily Show recently ran a clip about AHLTA vs VistA. (embedded below for convenience)

One of the interesting side-stories from this is the open-source vs proprietary angle which Stewart did not address.  The VA was (is?) a big supporter of Open Source Software.  (It is less clear how much commitment remains, now that both Roger Baker and Peter Levin have left the VA.)

An Open Source Software model makes perfect sense for VA. They had the business problem of 133 treatment facilities with 133 custom versions of VistA.  One of the beautiful things about VistA was that it was open to customization at the various installations so that it could be tailored to specific needs and this allowed innovation at point of service.  The problem is that the overall operational cost increases over time as the versions diverge, and there is the possibility that interoperability decreases.  The VA created OSEHRA to bring these forks back together.  By using open source methodologies, they created a common “VA Enterprise VistA” baseline, gives a place for all those local improvements to be merged into a best-of-breed VistA.

This collaborative model is a huge win for innovation and continuous modernization.  Allowing local innovation is both good and bad: the innovation part is good, but the loss of standardization is bad.  Coupling a tolerance for local innovation with a enterprise reference standard makes the prospect win-win.

I’ve personally fixed three bugs in the Linux kernel, and successfully gotten those patches incorporated into the Torvalds-approved kernel.org kernel. I fixed the bugs because they affected me personally.   I worked to get them into the upstream because I didn’t want to have to keep re-applying my patches every time a new kernel was released.  There is also a non-trivial pride and ego-boost associated with that accomplishment.  These same incentives will cause VA doctors and IT staff to work to improve VistA locally, and also to merge those changes into an enterprise baseline.

These arguments in favor of an open-source development model could apply to the DoD also, or to a joint DoD-VA approach.

What’s not clear to me is how much VistA should play a starring role in that future.

Here’s an issue:  building a vibrant, collaborative community around a software development project is about people and process as much as it is about technology.  Some great books have been written about this.  It will be difficult to get bright, talented software engineers to work on VistA, because of the 30-year old tools and design practices.  I have two degrees in computer science from MIT and you couldn’t pay me enough to work on VistA.  Literally.  Even if you aren’t a software engineer, take a look at this random sample of VistA source code, which is barely distinguishable from line noise:

Not all the VistA code is this bad; some of it is worse.

That said, the DoD alternative (AHLTA) – and in fact the most well-known proprietary alternative  – all share the same obscure programming language (MUMPS) and are almost certainly equally bad – but since their code is not public, it’s harder to critique them.  In fact, I would expect them to be worse since they were not written with collaborative development in mind.

Say all the nice things about MUMPS you want:  In the end, the choice of an ugly, archaic technology will decrease interest in any project by prospective contributors, thus decreasing the value of the collaborative model.  This is Technical Debt we may not be able to repay.

Interestingly, Philip Newcomb, CEO of The Software Revolution Inc., has asserted that his company’s technology could convert VistA from MUMPS to J2EE in about a year for $10m. If true, this would be a bargain, IMHO.  I’ve met with Phil twice in the past decade, and his claims are impressive, although I have no personal experience with the results of his company’s work.  Other companies perform similar services – Hatha Systems for example claims to do automated analysis of MUMPS.

Tom Munnecke, one of the original architects of VistA has eloquently defended the MUMPS database design, pointing out that medical data is rarely suited to the structured, SQL-esque approach of relational databases.  He makes some fabulous points, and I actually think that he’s right in that many of the decisions that were made for MUMPS and VistA were remarkably prescient.  It’s taken the rest of the IT world three decades to rediscover document-structured non-relational databases, now known collectively as NoSQL.  Now that there’s a huge-amount of energy and expertise focused on large-scale non-relational data stores, maybe we should consider how to use that talent and energy for EHR?

In short, I think the VA should keep doing the OSEHRA thing to consolidate and modernize VistA.  There’s two threads to that:  first, they need to consolidate into an enterprise version of VistA for the VA to bring together the forks (which they are doing), and second, they should refactor and modernize the architecture and the tooling (which they claim they are doing).  I am suspicious that they aren’t being bold enough, but I don’t know.

I remain skeptical that VistA can survive in the long term as a vibrant, community-driven open source project, if it continues as it is.  In order to make VistA a viable project, the current MUMPS-based database need  to be replaced with a modern NoSQL datastore of some kind, and the hyper-abbreviated MUMPS code needs to be replaced with something readable and maintainable.  A colleague of mine (David Wheeler) once pointed out that MUMPS code doesn’t have to be unreadable, but the coding practices of VistA do not lend themselves to readability.  A bold step would be to re-write the thing in Java or some other modern language; a mimimalist step would just re-write it in MUMPS that doesn’t suck so much.  In  David’s words:

I think you should note another alternative as well: Keep MUMPS, but translate the current MUMPS into readable code.

Yes, you’d still be working in an uncommon language.  But that transformation would be especially trivial to do (and trivial to automate), and the risks from auto-translation would be far lower because the underlying environment and assumptions would be unchanged.

It seems to me that the big problem here isn’t really MUMPS, it’s the way MUMPS has been used.  Developers have used MUMPS’ “you can abbreviate anything” combined with “use bad names”, which perhaps made sense 30 years ago but is a bad idea today.  But you do not *HAVE* to create ugly code in MUMPS.

Using the Wikipedia MUMPS article example, here’s some line noise:

hello() w "Hello, World!",! q

But here’s legal MUMPS – it’s the same code, but unencrypted:


hello()
    write "Hello, World!",!
  quit

I have no idea if translating to another language would be a better trade-off than translating it to readable MUMPS.  But it’d be easy to hire somebody to briefly investigate the options, pros, and cons, so that a reasonable decision (based on EVIDENCE) could be made.  And I think, in fairness, that alternative should be considered.

I also have concerns about the governance model of OSEHRA, but, as this blog post is already too long, I’ll save that for another article.

As promised at the top: Jon Stewart on AHLTA vs VistA:

Alas, this video is no longer available on Comedy Central. It was from March 2013, and was hilarious but tragic. If you can find it, post a link in the comments.
