More EMR Parodies….

I must be on an EMR parody kick. This one I found on Meaningful HIT News with Neil Versel (

Dilbert: EMR Fun

Saw this Dilbert comic the other day. Great EMR Fun. As an EMR practitioner and implementer, I found this to be very funny. For the non-geeky Star Trek fan, check out "PON FARR" reference.

Using SMS Technology In Healthcare

So, I came cross this link fon twitter(@vwadhwa). It talks about how through the use of SMS text in India Emergency Healthcare is brought to rural India.

I have been to India once and would go back in a heart beat. It is simple amazing the use of cell phone technology and SMS throughout India. Power maybe have the occasional brownouts, but the cell phone and texting will live on.

What I like about this use of technology is rather than bringing in technology, the group adapts technology that already exists.

An Great Day in San Francisco

IMG00105-20110202-1328While I am not here to gloat, well, okay just a little. The last couple days in San Francisco has been picture perfect. This was a shot from Greens in Fort Mason. If you never been, you have to go. Great food.

Batch Scripting Fun: Playing with Random Numbers

Proof of Concept:

Today, I needed to generate a random number between 1 and 5. Depending on what random number came up, would determine what IP address from a pool of IP address the user would be assigned.

Maybe I had Craps on the mind, but this problem reminded me of dice rolling. All-be-it a 5 sided die. So to test, I thought that I would write a simple Batch script that would generate a random number between 1 and 5.

I had a pretty good idea that I would use the %Random% operation to generate a random number between 0 – 32767. Then I would limit that to between 1 and 5.

My first attempt turned out like this:

set num=%random%
if /i %num% GTR 5 goto loop
if /i %num% LSS 1 goto loop
goto finish
echo %num%
pause >nul

Now it worked but it was slow because if you think about it, I would have to recalculate %random% every time the number was greater than 5 or less then 1. I needed to speed this up.

I knew that math would be the answer. I came across this Simulate a Dice Roll through a Google search. It showed that I was on the right track. I just tweaked it a little to at some logic to be able to run a command after finding the random number between 1 and 5.

@echo off

set /A num=%random% %% 5 + 1
goto NumberFound

if %num%==1 goto one
if %num%==2 goto two
if %num%==3 goto three
if %num%==4 goto four
if %num%==5 goto five

REM Enter next item to do here
echo %num%

REM Enter next item to do here
echo %num%

REM Enter next item to do here
echo %num%

REM Enter next item to do here
echo %num%

REM Enter next item to do here
echo %num%


As you see. The random number is generated and depending on the number 1 through 5, the next set in the Batch script can be executed. While this is a very simple programming 101 type of question, this shows how you can turn an classroom exercise into a practical application.
