Hi Developers!

InterSystems Online Programming Contest is over. Thank you all for participating in our IRIS Competition!

As a result - 20 great apps! And now it's time to announce the winners! 

Hey Developers!

Want to beat the COVID-19 pandemic with InterSystems and MIT? Please take part in the MIT COVID19 Challenge!

It's a 48-hour virtual hackathon with the goal to develop solutions that address the most pressing technical, social, and financial issues caused by the COVID-19 outbreak.

And it's your chance to build a solution on InterSystems IRIS for the COVID-19 crisis! 

I know that collection is instance of %AbstractList.

But what about $listbuild? Does it possible to detect that given variable is instance of $lb?

I am glad to say that VSCode-ObjectScript reached 4000 installs. Thanks to all of you who use it in their work.

VSCode-ObjectScript is an extension for VSCode which allows you to develop InterSystems based applications on ObjectScript using the modern code editor developed by Microsoft. Choice #1 editor amongst all developers worldwide by Stackoverflow survey 2019.

Some short notes about how to install and configure it you can find here.

If you need any help with a migration process of your development team to VSCode, please contact us by info@caretdev.com.

Hi developers!

When @Evgeny Shvarov announced the first InterSystems IRIS Programming Contest, I started looking for new ideas. 

I put together a few ideas, and that's what isc-utils is about.

• Conversions
  • Temperature
  • Length

• Exchange Rate
• Weather

Temperature Scale Conversion

IRISAPP>write ##class(diashenrique.Utils.Temperature).CelsiusToFahrenheit(28)
82.4

IRISAPP>write ##class(diashenrique.Utils.Temperature).CelsiusToKelvin(28)
301.15

IRISAPP>write ##class(diashenrique.Utils.Temperature).FahrenheitToCelsius(82.4)
28

IRISAPP>write ##class(diashenrique.Utils.Temperature).

Hi Developers!

Create Database, Namespace, REST Applications using Portal Management is an easy task. You just need a few clicks or maybe more clicks than you expect.

But, what if you traded all those clicks for a simple command-line ?!

IRISAPP>do ##class(diashenrique.Utils.GenerateDB).CreateNew

You just need to answer a few questions: 

Do you want to create a new Database/Namespace? (Y/N) : 

Choose your Namespace name : 
Choose the Dataset location <Path Default is mgr directory> :
Make this an Interoperability namespace?

Hi Community!

The registration phase for InterSystems Online Programming Contest ends today and we will start the voting week!

Now we have 20 applications - so you have a set of applications to choose from!

How to vote?

This is easy: you will have one vote, and your vote goes either in Experts nomination or in Community nomination.

Hello,

I got the idea for this application, because for my work we have a process that currently uses legacy Vista code called MailMan to transfer files using email. I thought I could create a process in HealthConnect (IRIS Interoperability) to replace the need for having the legacy code. I have seen File Passthrough and TCP Passthrough Operations that can transfer a stream (file content) into a file or through TCP connection. I did not find Email Passthrough Operation, so I decided to create it. It receives request with a stream that has the content of the file.

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

Class eduardlebedyuk.changePasswords Extends %RegisteredObject
{
ClassMethod test()
{
set ns = $namespace
zn "%SYS"
set NewPass = "NewPassString"
set rs=##Class(%ResultSet).%New("Security.Users:List")
set st = rs.Execute()
while rs.Next() { set st=$SYSTEM.Security.ChangePassword(rs.Get("Name"),NewPass)}
zn ns
}
}

DISCLAIMER: I am not an InterSystems engineer or a professional ObjectScript developer.

I just want to share my opinion about some things I am really miss in ObjectScript.

I really appreciate everyone who support my project (Declarative ObjectScript) in contest

but the post is not about "why you should support me" on contest.

I faced with ObjectScript in the university while was working on my diploma (in 2013).

Very good mentor @Evgeny Shvarov helped me to get started with ObjectScript development.

Starting in March 2020, Microsoft plans to release a series of security updates that will cause Windows Active Directory (AD) servers to reject unencrypted simple binds. For more details on the changes to Active Directory, see Microsoft’s Security Advisory ADV190023.

Instances of all InterSystems products using LDAP with Windows AD servers for user login can be impacted if they are not already properly configured to use TLS/SSL. The impact is not limited to instances running on Windows versions.

I hope you already know one of my projects Cache Blocks Explorer. I've recently renamed it to Blocks Explorer.

For the recent contest, I've added a new feature, the ability to generate a static picture of any Cache or IRIS database. Like below. Where unique globals have a unique color. This is how looks like inside 9.5GB database. Where 1 pixel represents one block. By link on image you will get even bigger image, with more detalization.

In Episode 6 of Data Points, certification manager Jamie Kantorjoins the podcast to tell us all about the InterSystems Certification program, what exams are currently being offered (and what ones are in development), and why it matters for developers and enterprises. Check it out!

InterSystems IRIS 2020.1 brings a broad set of improved and new capabilities to help build important applications. In addition to the many significant performance improvements accrued through 2019.1 and 2020.1, we are introducing one of our biggest changes in recent SQL history: the Universal Query Cache. This article provides more context on its impact to SQL-based applications at a technical level.

InterSystems has corrected two defects that, in rare circumstances, can result in data integrity corruption after running global compaction, database compaction, or database defragmentation. InterSystems recommends avoiding these utilities until after applying the corrections listed below.

1. The first defect is caused by database compaction, defragmentation, or global compaction, and can result in database corruption. If you have used one of these utilities on a database, InterSystems recommends that you perform an integrity check on it. This will identify any data corruption that has occurred.

For standalone installations I always recommended to use custom namespaces and not the USER namespace.

However, what about Docker?

In many Dockerfiles I see the creation of additional namespace, but why, if only one namespace is required?

What do you think?

We have a data transformation where source is object collection (populated from a json file)  and target is EnsLib.EDI.XML.Document.

If source file is large enough, transformation fails and we get <store> error and I quickly found this:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EBPLR_DTL_foreach which at the bottom in "Avoiding <STORE> Errors with Large Messages" section tells to: 

"As you loop over segments in a message or object collections, they are brought into memory.

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

I'm building a container from store/intersystems/iris-community:2019.4.0.383.0 .

I need to add my folder to the LD_LIBRARY_PATH  so that my custom shared library would load at runtime.

How can I do that?

Here's what I tried:

ARG IMAGE=store/intersystems/iris-community:2019.4.0.383.0
FROM ${IMAGE}

USER root

ENV MYDIR /usr/mydir

ENV LD_LIBRARY_PATH $MYDIR:$LD_LIBRARY_PATH

RUN mkdir "$MYDIR"; \
	chown -hR $ISC_PACKAGE_IRISUSER:$ISC_PACKAGE_IRISGROUP $MYDIR; \
	chmod -R 777 $MYDIR; \
	echo "LD_LIBRARY_PATH=\"$MYDIR\"" >> /etc/environment; \
	echo "$MYDIR" >> /etc/ld.so.conf.d/my.

⏯ InterSystems IRIS Cloud Roadmap

Hi all. Yesterday I tried to connect Apache Spark, Apache Zeppelin, and InterSystems IRIS. During the process, I experienced troubles connecting it all together and I did not find a useful guide. So, I decided to write my own.

Introduction

What is Apache Spark and Apache Zeppelin and find out how it works together. Apache Spark is an open-source cluster-computing framework. It provides an interface for programming entire clusters with implicit data parallelism and fault tolerance. So, it is very useful when you need to work with Big Data.

Hi, 

I know there are several alternatives, but I would like to find the easiest & simpler ones to store data coming in Json format from post requests and also allowing me to do SQL queries. 

I want to have a property called favouriteColors. I want to store a few colors, and I want to be able to do queries to get top favorite colors, etc.

Someone have experience consuming special wss ?

I need generate this values on Iris :

you can see an example here : 

https://github.com/Axway/axway-open-docs/blob/master/conversion_outputs/apigw_polref/content_sign_message.md

for any help,  Thanks in advance
