Hi.
How can I add/substract hours from $Horolog in ObjectScript and the date part of $H is also affected?

Hi Community,
Find out how you can use the open-source iKnow engine in Python within InterSystems IRIS.
Hi,
I use terminal + dbeaver,When I open the new terminal again, will prompt the license information.
Is this database free?
Image search like Google's is a nice feature that wonder me - as almost anything related to image processing.
A few months ago, InterSystems released a preview for Python Embedded. As Python has a lot of libs for deal with image processing, I decided to start my own attemptive to play with a sort of image search - a much more modest version in deed :-)

---
In order to do an image search system, fist it's necessary select a set of features to be extracted from images - these features are also called descriptors.
Since I started to use internet (late 90's), I always had a CMS (content management system) present to make easier post any information in a blog, social media or even an enterprise page. And later years putting all my code into github I used to document it on a markdown file. Observing how easy could be persisting data into Intersystems IRIS with the Native API I decided to make this application and force myself to forget a little of SQL and stay open to key-value database model.

It is the short name of WEB LOG, essentialy a platform

Hi,
When wanting to use VS-Code for server-side editing.. - In VS-code I can right click on a server item (eg a class) to see a set of menu options including 'Server Source Control... ' and 'Server Command Menu...' at the bottom.
I noticed that these options are somewhat connected to my server-side source control hooks class that inherits from %Studio.SourceControl.Base, however, I am seeing different behavior between my custom subclass of this, and, the provided %Atelier.SourceControl subclass.
How should the subclass of %Studio.SourceControl.Base be developed for these menus to be useable ?

Hi,How to specify column name (ddl)?
I cannot find those folders under my IRIS install dev folder. Those were in my cache install dev folder.
Will InterSystems drop those support? If yes, why are there some discussion about Python/Iris in this forum?
Of course, I wish IS continue to support those.
The pandemic that struck the world in 2020 made everyone follow the news and the numbers that involve the COVID-19.
Why don’t you take that opportunity to create something simple and pleasant, to follow the number of vaccinations worldwide?
To face this challenge, I'm using the data provided by Our World in Data - Research and data to make progress against the world’s largest problems.
They have a dedicated repository on Github with the data of COVID-19, and I took the vaccination data to help me with my tracker.
If you didn't know the guys, check it out, it well worth your time. Github
ZPM is a fantastic package management product. I have 7 apps published and these apps not using zpm because it need install external products using apt-get install.
Is it possible do apt-get install using ZPM?

I've submitted what I've called qewd-jsdb-kit-iris to the Multi-model competition - it's a suite of applications and tutorials that demonstrate how IRIS Global Storage is used to provide the unique Node.js-based "persistent JavaScript Objects" of QEWD-JSdb (what I refer to as the JavaScript equivalent of the ^ symbol that distinguishes Global data storage from in-memory data).

Hi colleagues!
Every day Johns Hopkins University publishes new data on coronavirus COVID-19 pandemic status.
I built a simple InterSystems IRIS Analytics dashboard using InterSystems IRIS Community Edition in docker deployed on GCP Kubernetes which shows key measures of the disease outbreak.
This dashboard is an example of how information from CSV could be analyzed with IRIS Analytics and deployed to GCP Kubernetes in a form of InterSystems IRIS Community Edition.
Added the interactive map of the USA:

Hi,
I'm a novice. I don't know much about object script. Can he write an(Windows10) EXE file?
Hello, developers!
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.
But more and more my wishes for the development of
The ObjectScript language of InterSystems IRIS has a very powerful metadata engine called XData. This feature allows the creation of metadata definitions for your classes, to be used by the compiler or by programs that will extend the standard features of the language, based on the XData definitions of its scope.
An example is IRIS Publisher, an Open Source application from the community capable of collecting all XData definitions in HTML and / or Markdown format and generating a Web Portal with all the application documentation assembled from these XData elements.

Hi,
Is there a database gui tool? like nactive?
Hi developers!
Often we need to deploy some data along with code pieces of the application.
And for InterSystems IRIS developers the question could sound: "How can I deploy the data I have in globals?"

Here I want to suggest to you one of the approaches - deploying global data using the ZPM package manager.
