CRLF to LF

For example we have a docker app that receives a .csv file from windows environment and then do some processing on it in docker linux environment.



Windows encode new line in CRLF format, but linux can understand only LF and throw an unexpected errors like

The "Ask Developer Community AI" tool is an excellent resource for studying for the certification. I asked it about each topic that will be covered in the test and the results are below.
Note: I classified each answer by the assertiveness that I consider as good, average and bad.

Note 2: The article has 4 parts, each one for an exam area.

As the title says, I've noticed that files that gets saved to the disk where the database lies (.DAT file) in the stream directory, does not get purged. Is this expected and do we need to create our own schedule task to clean this folder up?

I could only find old answers that say this, however I find it a bit odd if that is the case because they are considered temporary files. Perhaps I do not handle the streams correctly in the code?

Over the past several years, the InterSystems Developer Community has accumulated more than 1,000 open-source projects. Many of them serve as examples and learning materials — but a significant number have become useful tools, libraries, integrations, and real-world components used in production.

Some of these projects are mine, and like many community developers, I’ve seen the same recurring problem:

  • It’s easy to create an open-source project.
  • It’s hard to maintain, support, and develop it sustainably — especially without funding.

Writing code is one thing.
Supporting it for years, keeping up with new IRIS versions, building CI pipelines, writing documentation, fixing issues, reviewing PRs — all of this demands both time and motivation, and the biggest motivator is often financial support.

This is not a new challenge.
The global open-source world has faced this for decades and has developed various models to support OSS ecosystems.

I believe it’s time for the InterSystems community to start a discussion about adopting a similar model.

HTML tag in IRIS

Hi,

After converting from Ensemble 2018 to IRIS 2024 I noticed that HTML tag is not recognized?

I just copied & pasted this same from Ensemble to IRIS and in Ensemble looks fine!?

Thanks

I know the next ones:

1. Place all different settings in environment variables. You have a different .env file for each environment, and you must add some code to Production for reading and setting these values. It's good for deploying into containers, but challenging for management when we have a large production. I mean, we have many settings that can vary depending on the environment: active flag, pool size, timeouts, and so on. Not only endpoints.

HL7 DTL formatting

I need a DTL to handle this.

Any ideas appreciated.

For all Prosthetics orders:
when ORC-1(Order Control) is "NW" (New Order), need to update OBR-18(Placer Field 1) based on PV1-2 (Patient Class) value.
assumption is that the selection logic is that all prosthetics orders with OBR-18 field is always blank.
Description :
If PV1-2 is I, insert I in OBR-18
If PV1-2 is O, insert O in OBR-18
If PV1-2 is E, insert O in OBR-18
If PV1-2 is P, insert O in OBR-18
If PV1-2 is R, insert O in OBR-18
If PV1-2 is B, insert O in OBR-18

Modern data architectures utilize real-time data capture, transformation, movement, and loading solutions to build data lakes, analytical warehouses, and big data repositories. It enables the analysis of data from various sources without impacting the operations that use them. To achieve this, establishing a continuous, scalable, elastic, and robust data flow is essential. The most prevalent method for that is through the CDC (Change Data Capture) technique. CDC monitors for small data set production, automatically captures this data, and delivers it to one or more recipients, including analytical data repositories. The major benefit is the elimination of the D+1 delay in analysis, as data is detected at the source as soon as it is produced, and later is replicated to the destination.

This article will demonstrate the two most common data sources for CDC scenarios, both as a source and a destination. For the data source (origin), we will explore the CDC in SQL databases and CSV files. For the data destination, we will use a columnar database (a typical high-performance analytical database scenario) and a Kafka topic (a standard approach for streaming data to the cloud and/or to multiple real-time data consumers).

Overview

This article will provide a sample for the following interoperability scenario:
