Good day, developers!

The "apptools-admin" project is not only a set of tools for the administrator, but a platform for the rapid creation of a prototype of any solution.
For example, Photo Album, Music Player, and Personal Library all come together in a user-friendly treasure chest design.

Load http:// your-host:your-port/apptoolsrest/a/infochest

Change the path to your treasure files and start viewing, listening or reading from any convenient device: desktop, tablet or smartphone.

Random Read IO Storage Performance Tool

New Tool Available

Please see PerfTools IO Test Suite for a later version of the Random Read IO tool.

Purpose

This tool is used to generate random read Input/Output (IO) from within the database. The goal of this tool is to drive as many jobs as possible to achieve target IOPS and ensure acceptable disk response times are sustained. Results gathered from the IO tests will vary from configuration to configuration based on the IO sub-system. Before running these tests ensure corresponding operating system and storage level monitoring are configured to capture IO performance metrics for later analysis.

Hi folks!

Sometimes when we develop a mockup or PoC there is a need for a simple interface that will provide data in IRIS in JSON against SQL queries.

And recently I contributed a simple module that does exactly that:

accepts SQL string and returns the JSON.

How to install? Just call:

zpm "install sql-rest"

If you install it in a namespace X it will setup a /sql endpoint to your system that will accept POST requests with SQL string and will return the result for you for the data available in the namespace X.

InterSystems API Management (IAM) - a new feature of the InterSystems IRIS Data Platform, enables you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement. And here's an article explaining how to start working with IAM.

In this article, we would use InterSystems API Management to Load Balance an API.

In our case, we have 2 InterSystems IRIS instances with /api/atelier REST API that we want to publish for our clients.

There are many different reasons why we might want to do that, such as:

  • Load balancing to spread the workload across servers
  • Blue-green deployment: we have two servers, one "prod", other "dev" and we might want to switch between them
  • Canary deployment: we might publish the new version only on one server and move 1% of clients there
  • High availability configuration
  • etc.

Basic JSON Compare

Hi Dev Community

I thought i would share a little method I knocked together to traverse and compare 2 JSON objects for basic equivilance. I'm currently working on some data migration, and wanted a basic sanity check to validate that the JSON output is basically equivliant between the old and new, excluding a few things like timestamps.

It's a basic little recurvsive method, that will bubble up any differences over a nested structure. It's very low tech, as that's all I need it to do, but I thought it might be useful for others?

Hi Community!

I'm sharing a little tool (REST service) to download interoperability messages from your browser.

You only need to:
1. Create a web application in Management Portal (e.g. /downloadmsg) and set DispatchClass=Util.DownloadMsg.
2. Call the tool using your browser passing the namespace and the message header id to download.
http://localhost:52773/downloadmsg/ns/mydev/msgid/17441

Hi developers!

Recently we announced the preview of Embedded Python technology in InterSystems IRIS.

Check the Sneak Peak video by @Bob Kuszewski.

Embedded python gives the option to load and run python code in the InterSystems IRIS server. You can either use library modules from Python pip, like numpy, pandas, etc, or you can write your own python modules in the form of standalone py files.

So once you are happy with the development phase of the IRIS Embedded Python solution there is another very important question of how the solution could be deployed.

One of the options you can consider is using the ZPM Package manager which is described in this article.

Hey everyone!

I recently learnt something new while working with WRC on an issue, and I wanted to share with everyone on the off chance it could help someone else.

Scenario:

Files are being inexplicably written to a folder on your server and, due to the number of files in the folder and general system throughput, it is not possible to work through the files to track down the source.

Websocket Client Embedded Python

This is a demo to make use of a simple WebSocket Client with Embedded Python in IRIS.

How to Test it

  • Run an Iris Session in Docker
  • Select your WebSocket Echo Server
  • Enter the text you want to send or generate it
  • Send it and see the result
$ docker-compose exec iris iris session iris "##class(rccpy.WSockPy).Run()"

*** Welcome to WebSocket Embedded Python Demo ***

A custom SQL index with Python features

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 :-)

Making a blog using Python + IRIS Globals

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.

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.

On a default VS Code installation, when you create a new file its language mode is 'Plain Text'

You have to click there to set another mode.

Luckily, there's a setting you can tweak to change this. It is called files.defaultLanguage

Set it to the ID of the language you want. Those IDs display in parentheses after each entry on the language mode selector.

Hi folks!

Just a very short note on if you want to add a cute Open Exchange shield like this:

in your GitHub repo you can do it by entering one line like this:

[![Gitter](https://img.shields.io/badge/Available%20on-Intersystems%20Open%20Exchange-00b2a9.svg)](https://openexchange.intersystems.com/package/csvgen)

In the URL place the path to your OEX page.

Thanks to the participants of contest for such a neat shield )

What other helpful Github shields do you know? Please share in the comments?

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:

Artificial intelligence has solved countless human challenges – and medical coding might be next.
As organizations prepare for ICD-11, medical coding is about to become more complicated. Healthcare organizations in the United States already manage 140,000+ codes in ICD-10. With ICD-11, that number will rise.
Some propose artificial intelligence as a solution. AI could aid computer-based medical coding systems, identifying errors, enhancing patient care, and optimizing revenue cycles, among other benefits.

Static Documentation Generators

Hi Community,

In the past, technical documentation of the source code and software products was generated in chm, pdf files and documentation generators of the programming languages themselves. This old approach had the following limitations:
1. Outdated documentation;
2. Non-interactive and difficult to consult documentation;
3. Layout unresponsive, unfriendly and not adherent to HTML;
4. Inability to customize the layout of the documentation;
5. Inability to have HTML 5 documentation online and offline.
6. Lack of Markdown support.
