Jupyter Notebook is an interactive environment consisting of cells that allow executing code in a great number of different markup and programming languages.

To do this Jupyter has to connect to an appropriate kernel. There was no ObjectScript Kernel, that is why I decided to create one.

You can try it out here.

Here's a sneak peek of the results:

Jupyter Kernels 101

There are several ways to create a Jupyter Kernel. I decided to make a Python wrapper kernel.

We have to create a subclass of ipykernel.kernelbase.Kernel and implement the do_execute method which receives a code to be executed in a

Hey Developers, 

Develop a Java application that connects to InterSystems IRIS® data platform relationally, natively, or with objects:

⏯ Using Java to Connect to InterSystems IRIS

There are many ways to generate excel files using Intersystems, some of them are ZEN reports, IRIS reports ( Logi reports or formally known as JReports), or we can use third party Java libraries, the possibilities are almost endless.

But, what if you want to create a simple spreadsheet with only Caché ObjectScript? (no third party applications)

In my case i need to generate reports that contains large raw data (the financial guys love them), but my ZEN/IRIS fails, gives me, what i would like to call  a "zero byte file", basically says java ran out of memory, and causes heavy load on the

The Carbon Footprint Counter application uses the GHG Protocol to measure carbon emissions on enterprises. The GHG protocol establishes comprehensive global standardized frameworks to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains and mitigation actions.

Building on a 20-year partnership between World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), GHG Protocol works with governments, industry associations, NGOs, businesses and other organizations. (source: https://ghgprotocol.org/about-us).

This might be a dumb question but I didn't see anything about it in the Mirroring documentation. Are processes that are currently running when the primary fails over to the secondary automatically switched over and continue processing? Or are they terminated and would need to be restarted on the secondary?

There was some embedded sql queries before that which worked fine however.

Hi developers!

Here is the score of technical bonuses for participants' applications in the InterSystems Climate Change Full Stack Contest 2022!

Hi, can anyone tell me how I should do the parameter calculation below in the MSM / MUMPS of Intersystems? STAP SIZE
STACK SIZE
MAX MODIFIED BUFFERS
DISK I / O RATE
SLICE COMMANDS
PARTITION SIZE
BUFFER POOL SIZE
NUMBER OF MUSERVER PROCESSES We have a rolling MSM that suffers from hangovers from the Activate service and the Workstation service several times a day and we are unable to determine if those hangouts are related to the number of users or overloading the system.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

In the second article, we covered GitLab Workflow - a complete software

I have followed the Article: Continuous Delivery of your InterSystems solution using GitLab, On our own Linux environment it works well but when I try to run it on a clients windows server; and the following command is run by the runner

irissession IRISHEALTH -U TEST "##class(isc.git.GitLab).load()" 

we get the following "error"

<NOTOPEN>>

I do not know why this happens, it does look like it has something to do with user rights but I am totally lost at this point as we have done everything I can think off relating to grant correct access etc.

Does anyone perhaps have something they can point me to

Let's say I have two lists of connected data where elements of listTwo only make sense if given an item of listOne as context:

listOne = ["A", "B", "C"]

listTwo = ["x", "y", "z"]

Tuples like ("A", "y") and ("C, "x") make sense, but "A" or "x" by themselves don't. I would like to pass in a list of such tuples into a method and have it handle each tuple in the list. So what would be the best way to format them given that ObjectScript does not have specialized tuples? Would it be nested $LISTBUILD lists or something else?

Hi guys,

I've a zen page report that I would like to export to .csv file, any ideas on how to do that?

Thanks

What's a good way to add a custom hyperlink to a table item in Clinical Viewer (CV2)? I am customizing the Diagnostic Studies page, and have a custom transform that returns the HTML code for the hyperlink. The hyperlink is supposed to open a custom CSP page in a new window or tab.

Using the layout editor, I then tried adding several "items" to the table like an Icon or External Viewer Link, and use the custom transform to get the hyperlink, but these items only show up as plain text and do not link to any page. How do I turn these items into a hyperlink?

Hi Guys,

is there a way to get an audit or a record of deleted records in a class?

so basically, I'm looking for way to track delete record or from which class or class method call that delete statement was executed,  my understanding is that so for example using %OnfterDelete  I can track any deleted record using %Delete(), so if the user execute a (Delete from myclass)   sql statement can OnfterDelete track that ?

the reason why, is that we have a class where records keeps disappearing (delete) from it and we don't know where or how is this happening, in our software we have 5 places where we

Hello everybody!

I’m having some odd issues with IRIS for health community edition and creating a new namespace.

Versions 2021, 2022.1 & .2 for Windows and Ubuntu allow me to create a new namespaces and the databases for it.

As you can see above, I’ve enabled the namespace for interoperability productions.

I’ve run this creation process with not copying the mappings, copying everything from user, and so on, with out a difference to the end result.

Now after this is done, for some reason, I run in to the issue below,

“The namespace does not support productions”- error pops up when I go to the

Hey Community!

If you follow our updates, you should know that several months ago we created a new regional community for all those people who speak (and write) French!

You can find it here: fr.community.intersystems.com

After only three months we already have 25 members (I know, it doesn't sound a lot compared to 11.000 members on English Community, but French Community is a newborn compared to an adult) and more than 140 articles, 3.000 views, and 160 likes. We already have exclusive content not present on other regional Communities and our own "thing" which you may spot in our recaps of different events where moderators and admins from the French Community were present.

Is there any way to dynamically generate the output filename for a schedule task?  For example when running a legacy code task every hour , is there anyway to specify the output file name to be appended with time stamp or some incrementing number to avoid overwriting ?

Hi! As a developer who was forced to move from Mac to Windows (temporary) I found some things a bit confusing. In this article I would like to talk about some tweaks I made to make my experience smoother. I think it can help not only Mac users who need to use Windows environment (for ex. in VMs), but also can help some Windows users to make some things more convenient. Of course, all the points are subjective, the best setup is one that works for you.

All the tweaks are related to Windows 10 as I don’t have an access to Windows 11 at the moment.

Is there a nice cheat sheet for the IRIS command line (terminal) application?

Hey Community, 

Enjoy watching the new video on InterSystems Developers YouTube channel:

⏯ Multi Model Capabilities of InterSystems IRIS

Hello,

I work on deploying IRIS using Kubernetes operator and Red Hat OpenShift. I encouraged another team working on Java application to consider using IRIS as database. My team deployed IRIS cluster using two mirrored data pods for the other team. The other team asked me for the connection information.

To learn how to use Java with IRIS, I attempted to deploy two apps from Open Exchange:

https://openexchange.intersystems.com/package/CRUD-GLOBALS-IRISNATIVEAP…

Here I got errors like this:

package com.intersystems.jdbc does not  exist

https://openexchange.intersystems.com/package/springboot-iri

Does anyone has an ini parser/writer in ObjectScript they can share?

Hi Community!

We're pleased to welcome @water huang as our new Moderator in the Developer Community Team!

Let's greet @water huang with big applause and take a closer look at his bio!

@water huang （黄念刚）is a developer at Southwest Technical Support Center of Mediway（东华医为）.

Here are some words from @water huang:

• Since I joined Mediway in 2012, I started to learn InterSystems technologies and integrated platform. I used the early versions of InterSystems Caché, Ensemble. Ensemble 2016 is my main development tool at present.
• I have worked in HIT for about 10 years, am familiar with HL7 V2/ V3, and

Say I have a persistent class in IRIS with an optional property EmailOptIn:

Class Person Extends %Persistent
{
Property Name As %String;
Property EmailOptIn As %Boolean;
}

I later realize that I'm doing a lot of null-checking on this property where I shouldn't need to. The solution is to make this a required property:

Class Person Extends %Persistent
{
Property Name As %String;
Property EmailOptIn As %Boolean [ Required ];
}

When I make this change I'll need to update all the existing data to set a reasonable default where it is null.
