The common requirement in many applications is logging of data changes in a database - which data has changed, who changed them and when (audit logging). There are many articles about this question and there are different approaches on how to do that in Caché.
I am trying to create a simple example of allowing binary (tiff) files to be selected and uploaded asynchronously to an IRIS for Health back-end. I have managed to write the HTML and Javascript which works great with regular text / ascii files, but fails with binary files.
When I upload a binary file (tiff) image I get garbage like this on the database server

For the recent contest, I've added a new feature, the ability to generate a static picture of any Cache or IRIS database. Like below. Where unique globals have a unique color. This is how looks like inside 9.5GB database. Where 1 pixel represents one block. By link on image you will get even bigger image, with more detalization.
In Episode 6 of Data Points, certification manager Jamie Kantorjoins the podcast to tell us all about the InterSystems Certification program, what exams are currently being offered (and what ones are in development), and why it matters for developers and enterprises. Check it out!

We are developing a Transformation and we are wondering: how could we debug and show a XML message which is being an output from a transformation, without storing it into request/response/callrequest/callresponse? We mean, how could we show a context variable in the production?
For example, let's have a transformation which stores an appointment in a variable called: context.especializadasConFormatoPrimarias
How could we show in the Production?
Currently it is being stored as the Transformation's output:
I just tried to log into our QA server and connect to Terminal (v 2013.1).
I can type in my username but when I attempt to type my password, no characters are typed. When I press ENTER the password is invalid.
I can connect to the management portal and the studio development environment without any problems. Also, I do not have this problem when connecting to the terminal in our production environment (2010).
Does anyone know what can cause this type of problem?
InterSystems IRIS 2020.1 brings a broad set of improved and new capabilities to help build important applications. In addition to the many significant performance improvements accrued through 2019.1 and 2020.1, we are introducing one of our biggest changes in recent SQL history: the Universal Query Cache. This article provides more context on its impact to SQL-based applications at a technical level.
InterSystems has corrected two defects that, in rare circumstances, can result in data integrity corruption after running global compaction, database compaction, or database defragmentation. InterSystems recommends avoiding these utilities until after applying the corrections listed below.

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.
In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.
In March we are starting our first InterSystemsIRIS Programming Contest! It's a competition in creating open-source solutions using InterSystems IRIS Data Platform.

And we provide winners with high-level badges on Global Masters.
We received the following error while publishing your package declarative-objectscript: ERROR #6901: XSLT XML Transformer Error: unable to determine file base pathname in at line 0 offset 0 InterSystems OpenExchange Team
The application I am working on for Iris Contest needs to send an email. Is anybody aware of a configuration for SMTP server, port, credentials that I can use for the contest or any demo application?
There are several options how to deliver user interface(UI) for DeepSee BI solutions. The most common approaches are:
use native DeepSee Dashboards, get web UI in Zen and deliver it in your web apps.
use DeepSee REST API, get and build your own UI widgets and dashboards.
The 1st approach is good because of the possibility to build BI dashboards without coding relatively fast, but you are limited with preset widgets library which is expandable but with a lot of development efforts.
The 2nd provides you the way to use any comprehensive js framework (D3, Highcharts, etc) to visualize your DeepSee data, but you need to code widgets and dashboards on your own.
Today I want to tell you about yet another approach which combines both listed above and provides Angular based web UI for DeepSee Dashboards - DeepSee Web library.
