are you curious which topics we are going to cover at this year’s Global Summit? You have come to the right place! I will provide you with a sneak peek of what you can expect from the areas I am responsible for.
I am an avid user of ZEN for over 10 years now and it works for me. But it seems that Intersystems are no longer actively developing it (or ZEN Mojo), the only published reference to this is here
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.
It's been 6 weeks since my original article - - - - -but I have been busy on this project
I have been looking at/thinking about a replacement for ZEN for around 12 months but only really started in depth 4 months ago. Also been in IT for long enough that I can "get a feel" for a product/technology and make decisions accordingly without going into great detail. Any new technology has a learning curve and I don't want to waste time and effort on something that won't fly. And, as always, I am looking to minimise the learning curve as I want to concentrate on delivering business benefit.
Some people are lucky enough to have a totally separate environment to run production in.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:
Git 101
Git flow (development process)
GitLab installation
GitLab WorkFlow
GitLab CI/CD
CI/CD with containers
This first part deals with the cornerstone of modern software development - Git version control system and various Git flows.
I this article I detail some strategic issues that a new development UI will need to address - these are the ones that I can think of now - others may come to light during this journey.
See the webinar by Eduard Lebedyuk here from the last Global Summit describing modern web development and Caché
And, as always, if I have missed something please comment....
IRIS brought us a new WOW feature - SHARDING ! Definitely a great thing! But how can I find out if it suits my actual applications? Is there a practical advantage to go for it with my well cooked transactional application? Or is it just for new still to be designed applications?
Hi All This is the index to a series of articles I hope to create over the coming months.
ZEN and ZEN Mojo are no longer being actively developed by Intesystems - this is a great shame as it is a fine product that works so well for business applications. However ZEN is a 15 year old product and I need a path forward to replace the ZEN UI with a supported development framework.
This article is an index of the other articles I have, or plan to write. - the articles will be subject to change as I develop my thoughts and climb the learning curve.
I bet that not everyone familiar with InterSystems Caché knows about Studio extensions for working with the source code. You can actually use the Studio to create your own type of source code, compile it into interpretable (INT) and object code, and sometimes even add code completion support. That is, theoretically, you can make the Studio support any programming language that will be executed by the DBMS just as well as Caché ObjectScript. In this article, I will give you a simple example of writing programs in Caché Studio using a language that resembles JavaScript. If you are interested, please read along.
InterSystems supports use of the InterSystems IRIS Docker images it provides on Linux only. Rather than executing containers as native processes, as on Linux platforms, Docker for Windows creates a Linux VM running under Hyper-V, the Windows virtualizer, to host containers. These additional layers add complexity that prevents InterSystems from supporting Docker for Windows at this time.
The question has come up several times and I saw mixed answers and no quick example
My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS . The tricky thing is to stop reading in time. The example just displays what you normally see in your console. it becomes useful if you look for things that you can't get from any $system.whatever()
Easily transform a CSV file into a personalized preview of DeepSee - InterSystems BI
AnalyzeThis can be found on InterSystems Open Exchange. Use the Download link to navigate to GitHub and begin installing the project. Follow the “Installation” section of the GitHub README.
No doubt bitmap indexing, if used with a suitable property, performs just impressive! But there is a major limit: ID key has to be a positive integer. For modern class definitions working with CacheStorage this is a default.
BUT: There are hundreds (thousands ?) old applications out in the field that are still using composite ID keys. Or - to name the origin - work on Globals with 2 subscript levels (or more). They are by construction excluded from our "Bitmap Wonderland".
InterSystems Data Platform includes utilities and tools for system monitoring and alerting, however System Administrators new to solutions built on the InterSystems Data Platform (a.k.a Caché) need to know where to start and what to configure.
This guide shows the path to a minimum monitoring and alerting solution using references from online documentation and developer community posts to show you how to enable and configure the following;
Caché Monitor: Scans the console log and sends emails alerts.
System Monitor: Monitors system status and resources, generating notifications (alerts and warnings) based on fixed parameters and also tracks overall system health.
Health Monitor: Samples key system and user-defined metrics and compares them to user-configurable parameters and established normal values, generating notifications when samples exceed applicable or learned thresholds.
History Monitor: Maintains a historical database of performance and system usage metrics.
pButtons: Operating system and Caché metrics collection scheduled daily.
Remember this guide is a minimum configuration, the included tools are flexible and extensible so more functionality is available when needed. This guide skips through the documentation to get you up and going. You will need to dive deeper into the documentation to get the most out of the monitoring tools, in the meantime, think of this as a set of cheat sheets to get up and running.
Hi all. Yesterday I tried to connect Apache Spark, Apache Zeppelin, and InterSystems IRIS. During the process, I experienced troubles connecting it all together and I did not find a useful guide. So, I decided to write my own.
If you are attending Global Summit 2018 please be sure to say hello to George James Software in the Partner Pavilion.
You are also invited to the informal lunchtime meeting we're hosting at Global Summit on Tuesday 2nd October from 1pm in Indian Paintbrush, a meeting room at the conference venue. We will be previewing the next versions of Deltanji, our integrated source code management solution, and Serenji, our editor and debugger.
"Telegram" is a well-known instant messenger, which provides an API for creating bots. The features of this API allow you to create bots with a wide range of functionality including receiving payments. With the help of the telegram bot, I solved a simple task - sending Alerts from Ensemble to Telegram.

I'm pleased to announce that Robert Cemper is a new Developer Community Moderator for 2018 year!
Robert joined DC in June 2017 and is responsible for a significant amount of experience, best practices and deep skills in InterSystems technology presented here in InterSystems Developer Community!
Congratulations, Robert! And thanks for your Yes to work as Moderator in InterSystems Community!
However, few people know what technology the agency chose for storing and processing the data collected by Gaia. Two years before the launch, in 2011, the developers were considering a number of candidates (see “Astrostatistics and Data Mining” by Luis Manuel Sarro, Laurent Eyer, William O’Mullane, Joris De Ridder, pp. 111-112):
I would like to share with you my experience regarding to debugging via Atelier.
I'm developing a REST API and would like to attach to a process when I call the API via a REST Client tool, for example Postman. The purpose is to inspect values from HEADER and BODY of the HTTP request during the debugging process.
Come on! How am I doing? I am going to demonstrate that by using a class from SAMPLES namespace.
1 - Open Atelier;
2 - Open your REST Service class;
3 - Go to the method related to the URI that you need to debug;
