Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!

Hello,

Recently I have been required to work with a method called ExportToStream.

The situation asks me to export a UTF-8-encoded JSON as a XML to be imported on old releases. Here's how I attempted to fulfill this request:

do $System.OBJ.ExportToStream("path/to/my/json/file.json", .stream,,,"UTF8")

The file is indeed encoded as UTF-8 and although the XML header denotes that it has been exported as UTF8:

<?xml version="1.0" encoding="UTF8"?

Hi Community!

We are glad to invite every developer who uses ObjectSript and VSCode plugin to the upcoming "Introduction to VSCode-ObjectScript" webinar on April 14, 2020 at 11:00 EDT. 

Speaker: @Dmitry Maslennikov, InterSystems Developers Advocate, CTO at CaretDev.

You will learn how convenient the development process can be already right now and what we are going to do next to make it even better.

Please check the agenda below.

I'm looking for a means to dynamically specify and/or limit the data from the source that goes into a cube at build time.

I have a single data class that defines my source, and as the data within this table/collection grows/changes over time, I would like to be able to control which records actually make it into the indexed cube, but I'm having a hard time (short of defining a stored procedure to use instead of the extent query) for populating my cube indexes.

hi all,

I am looking to make a JDBC connection to my Intersystems Cache using the JDBC driver 2.0.0.

I see the connection format is as "

   jdbc:Cache://<host>:<port>/<namespace>

"

What I really want to do is filter additionally by a certain database, i.e. connect my consuming application to a database under the namespace.

how can I do that? what will be the format

Hello all,

I'm new to the Intersystems development world and I've been trying to figure out how to make a REST API using ObjectScript. I found a tutorial that I've been following that has been great and I'm trying to translate what I've learned to live data.

My question is "Is there a way I can set a variable inside of a class so when I call a routine that variable will be recognized?" I'm capable of setting the variable in a terminal session and then calling the routine and everything will be work great! I will get the data I want returned.

Hi,

Is there a way to hide a property in Data Transformation UI in Interoperability for IRIS?
I would like the property not to appear in the list of available properties to set.

Thanks,

Hi,

Newbie Question.

I have a Staging table i want to populate by running a Stored Procedure  and then query the same table with some sort of SQL inbound Adapter.

is this possible or do i need to create a separate service for this? 

Thanks

As per title, is it possible to print from meditech to an ensemble interface directly and has anyone done it?

I see meditech has a port and host option for setting up a printer, so I'm curious.

Hi, this might be a silly question, but how can I start a job in ensemble? I am getting the update button, and my business service is not restarting.

it says 1 new job to be started, but where can I start the job? Would appreciate your help on this

I have Mac OSX and Docker Desktop 2.2 (Engine 19.03).

I have a REST service running on my localhost (Mac) and I was trying to consume it from IRIS running in a Docker container.

If you try something like that don't use localhost as HTTP Server setting (using a Business Operation for example).

You have to use host.docker.internal.

Hello, everyone, 

InterSystems Certification has designed another certification exam and we need input from our community to help to validate its topics.  Here's your chance to have your say in what makes an expert in system administration with InterSystems Caché or IRIS. And, yes, we'd like to hear from you Caché admins!

Here's the exam title and the definition:

InterSystems IRIS System Administration Expert

An IT Professional who:

• designs, installs, and maintains complex InterSystems IRIS environments, and
• ensures data security, integrity, and availability. 

So, how can you help?

Full-Stack JavaScript development allows you to create state-of-the-art applications with Caché. With any (web) app you build nowadays, one has to make a lot of architectural decisions and you want to make the right ones. With the Node.js connector available for Caché, you can create a very powerful server side application server, allowing you to use the latest JavaScript technology and frameworks client- and server-side.

With all these new technologies, the most important is to integrate them in the most efficient way and to create a very productive development experience. This article willl get you started step-by-step with Node.js technology.

In Episode 7 of Data Points, product manager @Carmen Logue joined the pod to tell us all about InterSystems Reports — the new reporting feature of InterSystems IRIS! Take a listen to hear about its capabilities, use cases, and how it fits into the existing set of analytics technologies.

I'm happy to announce the release of the interface to Julia programming language for InterSystems IRIS. Execute Julia code and more from InterSystems IRIS. This project brings you the power of Julia right into your InterSystems IRIS environment:

• Execute arbitrary Julia code
• Seamlessly transfer data from InterSystems IRIS into Julia
• Build intelligent Interoperability business processes with Julia Interoperability Adapter
• Experiment in Julia Shell, right inside your InterSystems IRIS terminal

Julia Gateway is a community project, available on OpenExchange.

I'm having trouble trying to navigate XML files USING the %XML.TextReader. I have read https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GXML_textreader#GXML_textreader_creating_method
but I still don't really understand. 

I have the following block

Hello!

This may seem a bit strange, but I'd like to make a business operation which would put a file via SFTP and then confirm that the filesize on the remote server is consistent with expectations.  I am thinking either of a custom copy or extension of the adapter (right now it is using EnsLib.FTP.OutboundAdapter) that overwrites method PutStream, or a version of the FTP.PassThroughOperation with a customized method OnMessage that does the check after the PutStream completes OK-- but I am uncertain of how exactly to modify either method to make the check.

My database service is on the cloud server, and I access it on the company intranet. When I user the %request.CgiEnvs  to get "REMOTE_ADDR", but what I have been getting is the company's external address. I can't get my IP address in the LAN. 
For example, my computer IP address is 192.168.11.11, and my company's external public network address is 214.17.17. I can only get 214.17.17 by using %request.CgiEnvs("REMOTE_ADDR"), but not 192.168.11.11.   

I only want to get 192.168.11.11.

Any help would be appreciated. Thanks!

Hello community,

I recently started to work with Ensemble. I defined a subclass of EnsLib.HL7.Message.  In my production I receive HL7v2 messages and transport them using the Message Router to a business operation. The operation class has an OnMessage method with parameter

pObject As MySubclassOfEnsLibHL7Message.

I expected that specifying the parameter type, on receiving the message an implicit type cast would be performed. However, $CLASSNAME reveals that my messages are still of type EnsLib.HL7.Message. How can I convert my messages in ObjectScript (without DTLs or something the like)?
