In last post I talked about iris-copilot, an apparent vision that in near future any human language is a programming language for any machines, systems or products. Its agent runners were actually using such so-called 3rd generation of agents. I want to keep/share a detailed note on what it is, for my own convenience as well. It was mentioned a lot times in recent conversations that I was in, so probably worth a note.

Hey Community!

We're happy to share the next video in the "Code to Care" series on our InterSystems Developers YouTube:

I am connecting to an intersystems cache database via C# and I need to obtain a list of all available namespaces.

I am using code like this:

           var C = new InterSystems.Data.CacheClient.CacheConnection(CS);
           C.Open();
           var Command = C.CreateCommand();
           Command.CommandText = $@"
               select * from %SYS.Namespace_List()
           ";
           var Values = Command.ExecuteReader();
           while (Values.Read()) {
           }
       }

The George James Software team is looking forward to going to National Harbor for READY 2026!

As part of the conference, we'll be hosting our Deltanji Source Control User Group:

Date: Wednesday, April 29th 
Time: 8 - 9am (breakfast will be provided) 
Location: Azalea 1 
RSVP by emailing laurelj@georgejames.com. 

We'll be showing what will be included in the next release of Deltanji, version 8.2, as well as providing an opportunity for questions and discussion. We welcome both current and prospective users to join us.

The Management Portal doesn't have a native way to switch to Dark Mode. This can be resolved using a Chrome extension called Dark Reader. See the result:

To install and use the Dark Reader:

Most IRIS developers use $LISTBUILD every day — often without even noticing it.

It is not just a convenient function for building lists. It is also the default internal format used to store row data, global values, and many intermediate structures inside the database engine.

Despite this, the actual binary representation of $LISTBUILD values is rarely discussed. Most developers rely on its behavior, but never look at how the data is really stored.

This article focuses strictly on the binary layout of $LISTBUILD values, based on direct inspection via zzdump.

I need a %SYS.Python object that will be accessible from different processes. The goal is to avoid reinitializing the Python object whenever it is called. Ways that I checked and decided that it is NOT what I want:

• %-variables (process variables). Reusing only in the same process
• Save-and-restore via globals. Restoring means heavy initialization, which I want to avoid

Next, my ideas (none of them look like a silver bullet):

• Using Interoperability Production.

Hi Guys,

I've this Business operation pointing to my DSN as below 

where its calling the this method, but for some reason its not recognizing Ens.Util.LookupTable class   

What is a Microservice?

A microservice is an architectural style that structures an application as a collection of small, autonomous services. Each component is developed around a specific business capability, can be deployed independently, and is typically managed by a miniature, specialized, self-governing team. (Source: https://microservices.io/)

During my work with customers and also following I often met the 
explicit or embedded question: What is this "GLOBALS" ?
I'll try to explain the history to unfold the context.

Has anyone done this successfully?  Customer wants to receive HL7 data over https using OAUTH 2.0 client credentials.  I am assuming a custom Operation will be needed?  I tried using CoPilot for assistance but was unsuccessful.  I am not great with Object script :( 

Hi Team,

We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.

Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?

Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.

Thanks,
Ganesh
