Hi Community,

New "Coding Talk" video was specially recorded by @Evgeny Shvarov for the second IRIS Programming Contest: 

⏯ Creating CRUD REST API for InterSystems IRIS in 5 minutes

Hello!

I need to create a .zip file with several files from% Stream.GlobalBinary objects. Can someone help me?

Hi Community!

The new video from Global Summit 2019 is already on InterSystems Developers YouTube:

⏯ Real World NLP Use Cases

This is the first in a pair of articles on SQL indices.

Part 1 - Know your indices

What is an index, anyway?

Picture the last time you went to a library. Typically they have books sorted by subject matter (and then author and title), and each shelf has an end-plate with a code describing the subject of its books. If you wanted to collect books of a certain subject, instead of walking across every aisle and reading the inside cover of every book, you could head straight for the bookshelf labelled with your desired subject matter and choose your books.

Hello Guys,

Can someone help me?

I'm triggering a Rest Services, my JSON is a String variable(Request.JSON), when I pass it on EntityBody.Write, WS returns me the 403 error.
When I pass Obj = {} it responds by saying that no Data has been sent.
So, my problem is to set the "Obj" with the String variable, I should convert it, correct? But how do I do this? My JSON is all in this variable.

MyCode:

        Set Dados = ##class(%Net.HttpRequest).%New(),
            Dados.Authorization = pBearer _ Request.Token,
            Dados.ContentType = "application/json"
 
        $$$TRACE(Dados.

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"?

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,
Blaise

Hi everyone,

Are there any tools to check the code coverage and to do a lint check for cache object script? Developers will be working with HealthConnect (IRIS based)

Thanks.

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.

Hi,
I have installed IRIS community version in my laptop which has Windows 10 OS, also I am already using Healthshare (Cache for Windows (x86-64) 2017.2.1 (Build 801_3_18178U)) in the same laptop. I tried to import objectscript package manager XML file which is downloaded from https://pm.community.intersystems.com/packages/zpm/latest/installer .

I am getting below output which installation failed. Please help to fix this.

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?

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:

⏯ Diving into InterSystems Cloud Technology

Hi Community!

We're pleased to invite you to the "Online Meetup with IRIS Programming Contest Winners" on April 3rd at 11:00 EDT! 

It's a virtual Meetup with some of the winners of the past InterSystems IRIS Online Programming Contest. 

What awaits you at this virtual Meetup? 

• Our winners bios.
• Short demos on their applications.
• A short interview with all the winners about the past contest. Plans for the next contests.

IRIS 2010.1 brought us a new feature: %Net.WebSocket.Client

As a continuation of my series of WS Clients I just couldn't resist to try it.
Well, this is the result and it was rather simple in the end.

• After I succeeded in my personal fight against Windows Firewall ;-)

You basically need to prepare 3 classes:

• Credentials for User, PW, SSL
• an Event Listener
• the Client (Could be a .MAC routine as well)

The example uses the WSS.EchoServer (a derivate from former SAMPLES in Caché).
The default assumption is to have Client and Server on the same system & namespace.

In Caché you had an example of a WebSocket Server in namespace SAMPLES
With IRIS the samples are gone and require additional installation effort.

So I refurbished the code with some useful additions:

• independent of namespace
• timeout control from client
• readable communication log

This contains 2 classes:

• rcc.EchoServer.cls
• rcc.WSScsp.cls for testing. Called from Browser by (http://localhost:52773/csp/user/rcc.WSScsp.cls)

The server is essential for the 'native' WebSocket Client Demo

Hi guys,

Couple days ago, a customer approached me with the wish to enhance their existing legacy application, that uses SOAP (Web)Services so it shares the same authorization with their new application API based on REST. As their new application uses OAuth2, the challenge was clear; how to pass access token with SOAP request to the server.

After spending some time on Google, it turned out, that one of possible ways of doing so was adding an extra header element to the SOAP envelope and then making sure the WebService implementation does what is needed to validate the access token.

GA releases are now published for the 2020.1 version of InterSystems IRIS, IRIS for Health, and IRIS Studio!

A full set of kits and containers for these products are available from the WRC Software Distribution site, including community editions of InterSystems IRIS and IRIS for Health.

The build number for these releases is 2020.1.0.215.0.

InterSystems IRIS Data Platform 2020.1  makes it even easier to develop and deploy real-time, machine learning-enabled applications that bridge data and application silos.

InterSystems has corrected a defect that can result in data integrity issues on systems using mirroring.

This defect affects:

• All currently released versions of InterSystems IRIS and IRIS for Health, except 2020.1
• Caché and Ensemble versions beginning with 2011.1.1
• All HealthShare products based on the above Data Platforms versions

This defect is more likely to be encountered in IRIS and IRIS for Health 2019.4. It is highly unlikely to have occurred on deployed systems running any other version.
