K9s is a terminal-based UI (aka kubectl clown suit), to manage Kubernetes clusters that drastically simplifies navigating, observing, and managing your applications in K8s, including Custom Resources like the InterSystems Kubernetes Operator (IKO) and ArgoCD Applications. If you are about to take your CKD, CKA, or CKS, leave k9s well enough alone for awhile as the abstraction to kubectl will become the standard for navigating the cluster and you will undoubtedly become estranged to the extended flags of kubectl and bomb the exam.
In this recent post I highlighted the importance of a CSP session's Key property in enforcing the level of security your web application may be relying on, and in particular the need to keep the property value secret.

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.
InterSystems Caché provides a GUI (Graphical User Interface) based Integrated Development Environment (IDE) called Caché Studio. Developers can use Studio to create and maintain applications.
Controlling Process Flow
Controlling Process Flow means controlling the execution path of code. The execution of code flows from the top to the bottom in a routine, except for the following:
This article contains the tutorial document for a Global Summit academy session on Text Categorization and provides a helpful starting point to learn about Text Categorization and how iKnow can help you to implement Text Categorization models. This document was originally prepared by Kerry Kirkham and Max Vershinin and should work based on the sample data provided in the SAMPLES namespace.
Twilio is a great tool for programmatically initiating and managing phone calls. In this example we'll go over basic account setup, create a Cache Class to manage our interaction with the Twilio API, and initiate a phone call from the Cache Terminal.
The full Class used in this example is available on GitHub as well.
I would like to share the history of the project - the ZAPM shell.
As soon as ZPM was implemented, I immediately began to think about how best to use it.
And immediately faced with the desire to move more quickly between namespaces, especially when there are more than 20 of them.
I had to leave the ZPM, move to the desired namespace and re-enter the shell.
I suggested an improvement - a new "namespace" command for easier navigation.
I didn’t wait - I did it myself. And so it went. If you need it, get ready to do it yourself.
When you run a routine in the terminal and an error occurs in the program, if you have not set the error trap properly, the program will enter debug mode as shown below.
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 ?!
I have an issue related to Visual Studio Code and its InterSystems extension when exporting routines from the database to the file system.
The code entered via the terminal editor is encoded in DOS code page 437, but when I export it to my file system, even if I set the file opening to DOS CP 437, the accented characters which are two bytes long cause problems.
If you are facing out the license expire warning message on your terminal ("*** Warning: This Cache license will expire in 3 days ***") and you do not want that message to be displayed, you can disable/enable that by rinning the following commands:
The DeepSee TroubleShooting Guide helps you track down and fix problems occurring in your DeepSee project. A common problem is finding less records than expected in a DeepSee Cube or a related Subject Area. The DeepSee TroubleShooting Guide suggests starting your investigation by checking the following:
