#InterSystems IRIS

@Robert Cemper is the most active and widely read member of the community (Best Seller!). So nothing better than learning InterSystems technologies from over 100 articles by him. I curated the articles, selecting the best ones by subject:

Hello everyone,

I am having a challenge with the IRIS community version in Docker with wsl2. Host machine is Win 11 and the IRIS/Ubuntu image is Ubuntu-20.04 from running 'wsl -l -v.

I am not able to reach the WebPortal in IRIS nor the Super User port. docker ps -a = containers.intersystems.com/intersystems/iris-community:2021.1.0.215.3   "/tini -- /iris-main"   3 weeks ago   Up 26 hours (healthy)   0.0.0.0:1972->1972/tcp, 2188/tcp, 53773/tcp, 0.0.0.0:52773->52773/tcp, 54773/tcp   iris

Hi Developers!

Sometimes we need to import CSV data programmatically to InterSystems IRIS either from CSV or from URL. And we expect the class with proper datatypes to be created and the data to be imported.

I published a module csvgen on Open Exchange which does exactly that.

If you just need the CSV file be imported into IRIS you can do the following:

USER>do ##class(community.csvgen).Generate("/usr/data/titanic.csv",,"Data.Titanic")

Class name: Data.Titanic
Header: PassengerId INTEGER,Survived INTEGER,Pclass INTEGER,Name VARCHAR(250),Sex VARCHAR(250),Age INTEGER,SibSp INTEGER,Parch INTEGER,Ticket VARCHAR(250),Fare MONEY,Cabin VARCHAR(250),Embarked VARCHAR(250)
Records imported: 891
USER>

Or if you have the CSV on the internet, e.g. COVID-19 Data on Github you can get the data in the following way:

USER>d ##class(community.csvgen).GenerateFromURL("https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/05-29-2020.csv",",","Data.Covid19")

Class name: Data.Covid19
Header: FIPS INTEGER,Admin2 VARCHAR(250),Province_State VARCHAR(250),Country_Region VARCHAR(250),Last_Update DATE,Lat MONEY,Long_ DOUBLE,Confirmed INTEGER,Deaths INTEGER,Recovered INTEGER,Active INTEGER,Combined_Key VARCHAR(250),Incidence_Rate DOUBLE,Case-Fatality_Ratio DOUBLE
Records imported: 3522

Hi Community,

Let's meet together at the online meetup with the winners of the InterSystems Datasets contest!

You'll have an opportunity to have a discussion with InterSystems Product Managers on new LOAD DATA functionality, Q&A on datasets, etc. Our winners' demo included!  

Date & Time: Thursday, January 20, 2022 – 11:00 EDT

It is becoming more and more common to see beautiful badges in the README.MD file with useful information about the current project in the repositories of GitHub, GitLab and others.
For instance:

Hey Developers,

It's time to announce the winners of the InterSystems Datasets contest! Are you ready?

A storm of applause goes to these developers and their applications:

Hi all,

I am testing asynchronous Bulk Data retrieve with a large EHR vendor. When I retrieve the bulk data, they are returning ndjson (CONTENT-TYPE of "application/fhir+ndjson; charset=utf-8"). If I attempt to process that content using JSON functions - I get

ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

For example, the following generates the error

s objArray={}.%FromJSON(quickStreamOut)

The error makes sense in that ndjson is not a valid json format (I assume at least).

For some years I missed being able to offer, to everybody interested in ObjectScript, a tutorial more or less complete, to start with ObjectScript. Something that could help more and make things easier to those new developers that come to our technology... something intermediate, halfway between the common "Hello World!", that doesn't really get you further, and the "Advanced Training", that is unaffordable because of lack of time,etc.

If there were something truly helpful not only as an introduction to the ecosystem, but as a starting point, as a boost, to really start to walk into ObjectScript and move forward by yourself... wouldn't that be awesome?

Intersystems IRIS supports SMB protocol to connect and read files from remote folders (//foldername)?

Hi contestants!

We've introduced a set of bonuses for the projects for the Datasets Contest!

Here are the projects that scored it:

Hello,

Does anyone have experience sending files using %Net.FtpSession?   I am not seeing any methods in the class for sending files and setting up an Ensemble production is not an option.   Any advice would be appreciated.  Thank you.

Hey Developers,

Let the voting week begin! It's time to cast your votes for the best applications in the Datasets Contest!

🔥 You decide: VOTE HERE 🔥

How to vote? Details below.

Previously I had published The Article about the dataset from a real webserver, which can demonstrate how can activity and load of the Apache webserver depends on day of week, search engines indexing and some network noise.

Now I want to describe one useful function for most of webmasters and system administrators who are interested in obtaining of exactly information about visitors, hardware usage, and also about errors that gaing to their clients.

Here it is

With the release of InterSystems IRIS 2021.2 Preview and all-new LOAD DATA functionality dataset can by added with Objectscript Package Manager (ZPM) 

Medical Datasets contains following 12 datasets. For dataset tables and data details please visit ONLINE DEMO by using SuperUser | SYS
