Purpose

Over the Easter Weekend I touched on some deep learning classifier for Covid-19 Lungs.  The demo result seems fine, seemingly matching some academic research publications around that time on this topic. But is it really "fine "? 

Recently I happened to listen to an online lunch webinar on "Explainability  in Machine Learning", and Don talked about this classification result at the end of his talk:

The above figure is also presented in this research paper: “Why Should I Trust You?

(We are in contact with IS support for this problem but I would like to ask Community too, perhaps somebody experienced this problem in the past)

Hello Community,

we need your help with Cache 2017.2 freezing on Linux machine.

Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.

Questions:

• Any idea what could cause WRTDMN freezing?
• What actions it makes sense to take in order to have enough info when the system freezes next time.

Hi -- at a customer site we have 8 Access Gateways, with a couple of different load balancers that decide which projects go to which subset of AGs.

We're about to go live with a project that uses a subscription, and we have that subscription pointing to one of the AGs.  What if that AG goes down?  The project is dead until the AG is back up.  The subscription forces us to pick an AG that's registered in the Gateway Registry -- I don't see a way to get a cluster or load balancer address in there.

Has anyone found a way around this?

I'm wondering if anybody has done an implementation of the https://www.shibboleth.net/products/service-provider/ interface in Caché / IRIS to have a application running in Caché / IRIS be acception the shibboleth tokens and data as  usage credentials.

Does anyone use EnsLib.ITK.DTS.Framework.Operation.DTSTransferFile ? and how id you manage the transition to MESH?

I just noticed this PR from 2011

https://www.intersystems.com/news-events/news/news-item/itk-2-0-0-compliance-for-intersystems-ensemble-makes-it-easier-and-cheaper-for-nhs-trusts-to-exchange-information/

which led me to this class EnsLib.ITK.DTS.Framework.Operation.DTSTransferFile 

Given this was 2011, and DTS (now called MESH) is widely used by GP practices , I'm hoping someone in the community used this class?

If so - how did you manage the transition to MESH in Jan-2017?

Hi,

Working with Atelier a valid COS sentence like this:

if $e(chunk,1,1)="""{

}

Throws Missing closing quotation mark error. Any workaround?

Thanks

Hi Team,

      We weren't able to start the InterSystems cache server. I attached error screenshot and console log details on below. 

Console log error:

Retry CLNDMN job start after timeout with last job error = <UNKNOWN ERROR>.
JOBTRACE: Create job indirect, rtnref = START^CLNDMN.
JOBTRACE: Create job by control, rtnref = START^CLNDMN, pid = 6944.
JOBTRACE: Timed out waiting for child (6944) to appear in PIDTAB.
Error: ERROR #5001: Cannot start CLNDMN job - Shutting down the system

Please guide me, how we resolve this issue.

Thanks & Regards,

FHIR Server and API Manager for MIT COVID-19 Challenge by Steven LeBlanc

This demo shows how InterSystems API Manager (IAM) can be used to view and test FHIR resources with InterSystems IRIS for Health. It comes pre-configured with a FHIR server, pre-populated with synthetic patient data. The new InterSystems API Manager (IAM) includes OpenAPI Swagger specs to quickly generate REST client code to work with many common FHIR resources.

Hi Community!

The registration phase for the second InterSystems Online Programming Contest has already ended, and now the voting week begins! 

We have 7 applications - so you have a set of applications to choose from!

How to vote?

This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

Hi community,

This article to give a description of my small library JSON Filter.

Why JSON Filter?

Search, sort data are common operations.

But … How to do this with JSON data?

You can use a %DocDB, It’s a good way for storing JSON and index the main properties.

However, JSON document is very flexible. It isn’t always possible (and not recommended) to index each properties to process the wished queries. A manual processing on a data subset is may be required.

In my opinion, this is not a funny part of the job. It’s a repetitive code with many loops etc.

Hi Developers!

Excited to share with you that this week we reached 250 applications published on Open Exchange!

Thank you for sharing your open-source and commercial solutions running on InterSystems IRIS with InterSystems Developers Community and make your coding life more effective and happier!

Hi,

I am looking foi an API to retrieve one namespace´s default web application name. We have use some code to setup links to event log/mesage trace for monitoring emails. In perticular we did this with ensemble where the default csp webapplication name always is something like csp/<namespace/. Anyway when it comes to a healthshare installation the default path seems to be csp/healthshare/<namespace>.

To have an easy solution working for an ensemble and healthshare environment I rather like to use an API instead of evaluationg the kind of installation and then hardcoding the links to use.

Hi Developers,

Hi

I'm working in a security issue of the system that says that once you are logged into a session 
and you save this cookie. You can go to another navigator and use this cookie to be registered. 

I would like to chenge this cookie once user is logged into my system but I can't logout and 
login again because all my cookies are removed.

Is there a way to change to cookie or renew it?

Thanks a lot.

HealthShare 2020.1 is now Generally Available!

The 2020.

During runtime I build an object which is essentially a wrapper over in-memory table:

I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)

What's the best way to expose the object to SQL?

Hi everyone,

The project IRIS History Monitor received an update, using ZPM and the built-in REST API /api/monitor/metrics.

Hello,

We would need to convert a message from the following class:

Class Mensajes.Request.Laboratorio.HL7Request Extends Ens.Request [ ClassType = persistent, ProcedureBlock ]
{ Parameter RESPONSECLASSNAME = "Mensajes.Response.Laboratorio.ACKResponse";

Property mensaje As %XML.GlobalCharacterStream(CONTENT = "MIXED");

Property idPeticion As %String(MAXLEN = "");

Property ExpedienteUsuario As %String(MAXLEN = "");

Property MessageId As %String(MAXLEN = ""); Property ContentType As %String(MAXLEN = "");

to a Request message which is composed by hl7 segments:

Class Mensajes.Request.Laboratorio.

I am developing a BPL with a delay process. 

The problem I have is when a message is delayed I cannot see a job id so whilst a job is in halt status I cannot see how i can then cancel the message? It obviously doesn't show up in queues as it isn't active either. 

Am i missing something?

Hi Community,

We just updated the "EVENTS" section on the Developer Community website! 

What's new? Now it includes an event calendar for InterSystems Developers.

Hi Developers!

As you know in the second contest we introduced technology bonuses. Learn more.

You can see what app got what bonuses in the Technology Bonuses menu:

And here I want to share with you which apps got the bonus. Here we go!

Hey Developers,

We're pleased to invite you to the "Best practices of in-platform AI/ML" webinar by InterSystems on April 28th at 11:00 EST/17:00 CET.

Hi,

I want to know if there is a way to manually change Primary to secondary  and vice versa?

I need this becasue we backup the two VMs (primary and secondary) and my idea is to make a script to when the primary VM is going to backup with Veeam change to "backup" on the mirror.

Thanks!!!

After the database is restored, the WIJ file may be incompatible, so I deleted the WIJ file, and it needs to be set manually at startup

MX: Mumps & eXcel Joining - But Why?

At medium and small manufacturing enterprises, there are many technological and financial problems for the solution of which Microsoft Office is traditionally used, more precisely its more engineering part: Excel.

This is not only a tribute to tradition, excel is truly an unsurpassed tool for economic analysis and technological calculations. The number of users is in the millions. And these are only legal installations. In addition, there are analogues in the form of Free Office, Open Office and other.
