Hello all,

I have a problem where one of our 3rd party systems is only able to accept HL7 messages with UTF-8 encoding but the originating messages have Windows 1252 encoding. Does anyone know a way in which I can change the encoding for the entire message from Windows 1252 to UTF-8? I have only been able to find the CONVERT method to change individual charachters but we would like to change the entire HL7 message encoding.

Thanks!

dotnet core

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon? At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

The OKR methodology (Objectives and Key Results or Objectives and Key Results) is used by the largest companies in the world (such as Google, Netflix, Spotify, BMW, Linkedin, etc.) for agile performance management. It was created in the 1970s by Andrew Grove, president of Intel, and introduced to the general public in his famous book “High Output Management”.

Around 1998 John Doerr, one of the world's top venture capitalists, after coming into contact with Intel's OKR, introduced the model to Larry Page and Sergey Brin, who started a small company called Google.

Hi,

I'm processing POP3 emails using the standard EnsLib.EMail.InboundAdapter adapter and %Net.MailMessage. I'm basically processing documents that are attached to received emails. This works fine if the document is simply attached to the email itself. But some systems are sending documents that are attached to an attached email which has content-type = message/rfc822.

How do I get the attached file from the attached email?

Hi everyone - In IRIS we would like to arrange the access of two users in such a way that each has access to exactly one (his) database only. Which resource does this (%DB_%DEFAULT allows each of the two users access to both databases). If you create new resources (%DB_Database1 and %DB_Database2) and then add them to individual roles (each for the user to), the access for the users, for example, via a REST client does not give the desired separation (instead once Ok, other database 401 Unauthorized both OK).

Hello Everyone

I am new to cache. I know there are 2 types of methods in cache. One is Instance method (Which can be call through object creation of particular class) and other is Class methods (which can be call through ##Class(MyPackage.Car).CarModels()).

I want to know the difference when to create a instance method vs when to create a class methods.

Thanks in advance!!.

I wanted to write it as a comment to article of @Evgeny Shvarov . But it happens to be so long, so, decided to post it separately.

Image result for docker clean all images

I would like to add a bit of clarification about how docker uses disk space and how to clean it. I use macOS, so, everything below, is mostly for macOS, but docker commands suit any platform.

Hello!

I call a Java-based web service from HC and get an error message back:

"ERROR # 6243: HTTP request to SOAP WebService returned response with unexpected CONTENT-TYPE: text / html; charset = utf-8."


The content (payload) that is sent from my HC-client is coded in iso-8859-1 but SOAP debug shows that Soap envelope to be sent with:

"Output from Web client with SOAP action = urn: submitFile
<? xml version = "1.0" encoding = "UTF-8"?> etc "

and I guess that's what is causing the error message?

A quine is a computer program which takes no input and produces a copy of its own source code as its only output.

Wikipedia.

How about a fun challenge?

The task is to write a quine in InterSystems ObjectScript. It can be a class, or a method, or a routine, or just a line to be executed in a terminal. You decide!

Here's some resources you might consider useful:

Hard mode: do not use source code access functions.

Here's my (extremely uninspired, I know) attempt:

Class User.Quine
{

/// do ##class(User.Quine).Test()
ClassMethod Test()
{
    set sc = ##class(%Compiler.UDL.TextServices).GetTextAsString($namespace, $classname(), .str)
    write str
}

}

It produces this output:

How many different ways of producing a quine are there in ObjectScript?
