Greg, I am not sure what the point of this is, but try it from a local xterm in

I think you will get the effect you are looking for.

[Hardhats-members] Re: Teaching and Learning
Joseph's and John's words reminded me of a course I once did with the World Health Organisation. Amazingly, I have the monograph in front of me, "Educational Handbook for Health Personnel", J-J. Guilbert, 1992. In it, they draw heavily on the work of Mager (mid-50s) and strongly advise that the workshop participants set their own objectives. The "instructor" then sinks into the background as the participants first identify their objectives, then work out how they'll achieve them, and show that they have, then find all the necessary information to do so. These types of workshops tend to start slowly - the biggest hurdle is often the participants overcoming their desire to be told what to do - but once they get going it is a real pleasure to behold...

If we could just capture the imputed value of the wasted dollars that are now spent (failed software projects, medical delivery, medical error, medical duplication etc..) I would imagine that one could fund hundreds of full time developers. If a VistA system could bloom to included a national "standard of care" then eventually we could add billions more what would otherwise go to liability premiums. I would estimate that there are at least 300,000 physicians in the US who are not using electronic records or management systems (or at least ones that they like) and would gladly pay $100/month/physician to realize the value of VistA in their offices. That gives you $360,000,000 a year to fund more development - just an estimate - would this be enough to fund the proper number of developers? Ismet -- Ismet B.

Re: [Hardhats-members] Fileman SEARCH frustration
OK. I have just spent at least 2 hrs trying to get it working, and I have failed again. I don't have apache2. I have scoured the net and have not figured out how to uninstall my apache and install apache2. Apt-get install apache2 --> can't find package. apt-get install apache-mpm-prefork --> no better. So I tried to reading over the older instructions: http://vista.vmth.ucdavis.edu/notebook/index/12.html (targeting apache) to see if I could somehow merge these with: http://vista.vmth.ucdavis.edu/notebook/index/48.html But I guess I am just not smart enough, or don't have enough background experience, to get this working. I have no idea how my current apache is linked into the RedHat9 system. It seems to be a low level service that is provided. Your new instructions specify to : copy file m2web-vista-site to /etc/apache2/sites-available/vista (I don't have an /etc/apache2/ directory) Your equivalent older instruction indicate to edit: /etc/httpd/conf/httpd.conf So I tried putting the content from your new m2web-vista-site into the httpd.conf file, in the section named: Virtual hosts. When I do this, stop the httpd service and then restart it. I get a failure to start. So something is wrong. Is there anyway you could provide up to date instructions for those (like me) not using Apache2?

On Jan 14, 2006, at 10:29 AM, Bhaskar, KS wrote: SSVNs are an attempt to provide a "standard" way to provide access to some features that were previously provided in a non-standard way on different MUMPSen. That sounds right. Unfortunately, M standardizes the names of SSVNs but not their behavior, Yes. so they are effectively useless as standards - it's much easier to accommodate differences in syntax than it is differences in semantics. I'm not quite sure what you mean here. In fact, one of my major complaints about the M standard is that it doesn't really touch on semantic issues at all, except in a very informal way. I'm not saying we need complete mathematical rigor, but a reasonably formal operational semantics would be nice. But be that as it may, I don't think I agree: syntactic forms without a semantic interpretation (whether we make it explicit or not) are pointless. The question is not whether or not you define new semantics but whether or not the semantics is formally specified. GT.M does not support SSVNs, in part for this reason. There were/are also some security concerns with some SSVNs. Maybe it doesn't need to be said, but I wasn't criticizing GT.M, just point out that you won't find these SSVNs on a GT.M system. -- Bhaskar === Gregory Woodhouse [EMAIL PROTECTED] "Einstein was a giant.

[Hardhats-members] Interleaving
How can you demonstrate the interleaving of jobs without disturbing
it with explicit synchronization? I actually did this in PLT Scheme
as follows
(define (the-body x)
(begin
(let loop ((i 0))
(begin
(if (< i 25)
(begin
(display x)
(loop (+ i 1
;The use of t1 and t2 here is an artifice to
;suppress display of the thread ID
(define t1 '())
(define t2 '())
(begin
(set! t1 (thread
(lambda () (the-body "A"
(set! t2 (thread
(lambda () (the-body "B")
where the output could be (it varies from run to run):
AABBBAAABB
Now, this almost looks like MUMPS. Instead of a named let, I can use
FOR, and instead of thread, I can use JOB, so it would seem natural
to write something like
JOB BODY("A")
JOB BODY("B")
where BODY is just a FOR loop
BODY(X) ;
FOR I=1:1:25 WRITE X
QUIT
But, of course that's not allowed, because background jobs can't
write to the terminal. A natural idea is to use a host file instead,
but then the test would say more about output buffering than anything
else.
Does anyone have any ideas?

I believe that your efforts in this direction would be much more productive starting from there.OK, you have convinced me. I am going to try to get it going again. We cooresponded about this several months ago. It was in a different e-mail account. I am right now trying to port all my old email into my gmail account to make the searching better. I have both to some degree in M2Web and will be working to provide much more extensive capabilities in the near future. The web based query editor uses AJAX techniques toaccess the metadata and to provide highly interactive on-the-fly point-and-clickspecification of output formats. I don't know that there is anything like this on the web for any other database. (If there is, please let me know so I might borrow some of theirideas. ;)Yes, but is your searching tied to html the same way that current VistA is tied to roll-n-scroll? Based on what you have said before, I think not. But we'll see, because I am going to want to use it without html interface ( i.e. programmer's api) One of the deep problems that I imagine you are wrestling with here is the fact that the MUMPS code generated by Fileman is even less readable than the code in the applicationsthemselves. I am thinking in particular of the extensive re-use of X and Y and otherextremely short variable names. Gosh, you can say that again! In my decompiled code, I spend a great amount of time trying to figure out what a variable is being used for and then commenting the code. What a waste of time! Not at all. This is a problem area that needs attention. At the least, your efforts shouldshed light on that and bring a solution a few steps closer. Still, it seems to me thatthere is a growing opportunity for synergy in focusing your energies on the web. I like your background code, but again, I don't really need a web interface (or so I think.)ThanksKevin
Re: [Hardhats-members] So...how do you stat a file?
SSVNs are an attempt to provide a "standard" way to provide access to some features that were previously provided in a non-standard way on different MUMPSen. Unfortunately, M standardizes the names of SSVNs but not their behavior, so they are effectively useless as standards - it's much easier to accommodate differences in syntax than it is differences in semantics. GT.M does not support SSVNs, in part for this reason. There were/are also some security concerns with some SSVNs. -- Bhaskar On Sat, 2006-01-14 at 09:01 -0600, Gregory Woodhouse wrote: > > On Jan 14, 2006, at 5:00 AM, Kevin Toppenberg wrote: > > > I'll be dumb.

[Hardhats-members] Changing out the Cache.dat in Cache
In the past if I shut down Cache all of the way, including under Services in the Control Panel, I could switch out the Cache.dat for a new one and start it up with no problem. That was a quick way to avoid reentering the mappings and test something quickly. Now if I do that, Cache will not start. I understand there is some way to sort of "unmount" the database and switch it out safely, but I have yet to discover where that is. Can anybody tell me how to do that? -- Nancy Anthracite --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

[Hardhats-members] Namespaces and modules
Something else that I think would greatly benefit the language is support for namespaces and modules, and it's a real shame that it wasn't properly standardized. Think about it: One of the biggest headaches of VistA development is having to assign name and numberspaces to each application. No one can even start writing code without a namespace! It would be so much easier if we could just place each module in its own namespace and not even have to worry about collisions. === Gregory Woodhouse [EMAIL PROTECTED] "One must act on what has not yet happened." --Lao Tzu --- This SF.net email is sponsored by: Splunk Inc.
