I've been preparing to take the InterSystems HL7 Interface Specialist certificate and on the page that explains the cert it lists one in-person class and one online course. I've been through the suggested online course but when I read through the practice questions there are a lot of things that aren't covered or mentioned in that course. Naturally I could go digging through the documentation but there is no specific guidance about what things to study.

Hi, Community!

Open Exchange (OEX) is getting more and more popular and more and more developers consider publishing their apps in the public package manager registry.

This is really great!

So the topic of thoughtful naming convention is getting more important and even critical. Let's discuss?

Hi Developers!

Recently we discussed the naming convention on packages we deploy and even made some choices.

Here I want to have a conversation on the naming convention for unit tests.

Of course, we wish every good library has unit tests. Here is the documentation and some good articles(one, two, three) regarding it on the Developer Community.

Let's decide on the naming of UnitTests packages?

The suggestion is that unit test classes will all start with the UnitTest package name.

E.g. if your library's class name is:

johndoe.lib.class

The related unit test class will be:

UnitTest.johndoe.lib.class

What about folders?

The suggestion is that unit test classes will live separately from source classes, e.g. in /tests directory.

Here is the example of a repository with unit tests that are named and placed according to the proposal.

What do you think?

Currently, the SQL privileges (SELECT, INSERT, UPDATE, DELETE) are managed at the tables level, which can be very tedious when you have to administer many roles in an organization, and need to keep them sync with a constantly evolving data models.
By managing privileges at the schemas level, will allow to give SELECT and other DML privileges to *all* or *several schemas* to a role|user, fixing the need to manually synchronize the new tables|views to the roles.

I'm scraping my way through some code that's been around for a while, and came across the use of $ZTRAP and (dear GOD) GOTO for trapping and handling errors.

In an effort to "modernize" it and make it, I don't know, less M-ish (sorry old-timers!), I'm replacing it with Try/Catch blocks.

Some questions:

1. Is this a dumb idea?
2. Anything I should look out for?
3. Did I hurt anyone's feelings?

And if the answer to number 3 is Yes, my deepest apologies ... I love you guys! 🤩

Hi All,

We have few queries which are simple selects . For simplicity let's say there is a query that joins two tables and gets few columns and both tables have no indexes.

Select Tab1.Field1, Tab2.Field2
From Table1 Tab1
Join Table2 Tab2
On Tab2.FK = Tab1.PK

When we do query plan for this it shows approx 6 million, however if we make a simple adjustment to the query

I am sure I came across this in the past with Cache and just saw this again in IRIS.

When rebuilding or swapping a DAT file for a database it retains the Resource of the DAT file, not the Resource of the Database it is being used for.

For instance, if I have a local Database called APP with a resource %DB_APP and I want to refresh the data from another Database called TEST that has a Resource %DB_TEST I can just copy the DAT file from the TEST folder to the APP folder.

I'm looking into finding ways to fetch data from cache efficiently and work with it with python - specially pandas.

i tried the following but i'm wondering if this is the most efficient way?

to run the stored procedure as %ResultSet inside cache in a classmethod and serialize the data to JSON

and then call that class method from python

Hello,

Thank you for reading this question, and thank you for your time and replies.

I was wondering which ways, tools, mechanisms, or vias would you recommend to teach to kids, teens, adults, being your sons / daughters or not; your passion or likelihood for programming and computers?

I know there are some programming free games like the following ones:

Hello everybody...

A question for anyone using InterSystems technology:

What are the biggest challenges you’ve faced either trying to hire developers that know ObjectScript, or trying to train developers on ObjectScript?

Hello, authors of projects published in ZPM.

We ask you to add a module.xml to the file. attribute Description and republish your projects.

To update the description of your module in the public register ZPM, update the release in Open Exchange please.

Thanks.

New month, new code golf!

You will receive a string with a label code with numbers and letters.
Our challenge is to check if this code begins with 1, 2, or 3 and ends with A, B, C, S, or R.
It should return true(1) if so or return false(0) otherwise.
As usual shortest solution wins.
