In the previous articles, we learned the basics of using IMAP protocol to handle messages from mailboxes in an e-mail server. That was cool and interesting, but you could take advantage of implementations created by other ones, available in libraries ready to use.

There are many ways to generate excel files using Intersystems, some of them are ZEN reports, IRIS reports ( Logi reports or formally known as JReports), or we can use third party Java libraries, the possibilities are almost endless.

But, what if you want to create a simple spreadsheet with only Caché ObjectScript? (no third party applications)

As you can see in my profile I teach at a university and I wanted to share my take on teaching IRIS (or Caché before it).

It’s been some time but I remember seeing a series of articles by @Yuri Marx earlier this year about the course “Developing with InterSystems Objects and SQL”. He actually gave a brief description of what’s done on Day 1, Day 2, and Day 3 with comments from instructor @Joel Solon. And I thought to myself, it may be interesting to share my experience.

Have you tried the InterSystems learning platform lab for IRIS IntegratedML? In that lab you can train and test a model on a readmission dataset and be able to predict when a patient will be readmitted or not, or calculate its probability of being readmitted.

You can try it without any installation on your system, all you have to do is start a virtual lab environment (Zeppelin) and play it around!

The InterSystems IRIS IntegratedML feature is used to get predictions and probabilities using the AutoML technique. The AutoML is a Machine Learning technology used to select the better Machine Learning algorithm/model to predict status, numbers and general results based in the past data (data used to train the AutoML model). You don't need a Data Scientist, because the AutoML it will test the most common Machine Learning algorithms and select the better algorithm to you, based in the data features analysed. See more here, in this article.

This is the third article in our short series around innovations in IRIS SQL that deliver a more adaptive, high-performance experience for analysts and applications querying relational data on IRIS. It may be the last article in this series for 2021.2, but we have several more enhancements lined up in this area. In this article, we'll dig a little deeper into additional table statistics we're starting to gather in this release: Histograms

The 2021.2 release of the InterSystems IRIS Data Platform includes many exciting new features for fast, flexible and secure development of your mission-critical applications. Embedded Python definitely takes the limelight (and for good reason!), but in SQL we've also made a massive step forward towards a more adaptive engine that gathers detailed statistical information about your table data and exploits it to deliver the best query plans. In this brief series of articles, we'll take a closer at three elements that are new in 2021.2 and work together towards this goal, starting with Run Time Plan Choice.

It's hard to figure out the right order to talk about these (you can't imagine how often I've reshuffled them in writing this article!) because they fit together in such a nice way. As such, feel free to go on a limb and read these in random order .

Hi developers!

ZPM Package Manager is getting more and more popular and thus the library of packages is growing.

And thus some solutions or samples can be built with InterSystems IRIS and one or two packages installed.

I want to share with you iris-docker-zpm-usage-template - a template that can be used exactly for this purpose.

In this article I will demonstrate basics of OAuth2 authentication with GitHub account with the help of online demo 
https://dappsecurity.demo.community.intersystems.com/csp/user/index.csp by using SuperUser | SYS

Creating REST API using InterSystems ObjectScript is very easy, but some recipes can help you into this process:

Not so while ago GitHub introduced, ability to very quickly run VSCode in the browser for any repository hosted there. Press the . key on any repository or pull request, or swap .com with .dev in the URL, to go directly to a VS Code environment in your browser.

This VSCode is a light version of the Desktop version but works entirely in Browser. And due to this, it has a limitation for extensions which was allowed to work this way. And let me introduce the new version 1.2.1 of VSCode-ObjectScript extension which now supports running in Browser mode.

How to check if the password is strong enough, so it will not be cracked very fast? And how to make a strong password?

I've developed a tool that may help with this. You can find it on OpenExchange. Install it with zpm

zpm "install passwords-tool"

This module will install just one class caretdev.Passwords, which contains a few helpful methods in it

When looking at system performance and capacity planning I need to know what processors a server is running.

In ^SystemPerformance Linux systems report Intel processors explicitly, for example:

In this article I will explain how to Authenticate, Authorize and Audit by code by using CSP Web Application along with Enabling /Disabling and Authenticate/Unauthenticate any Web Application.
