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.

Hello everyone

I am new to cache. In an interview i was asked how to optimize a sql query.

I just said I will create index on conditions which are present in where clause. But as per interviewer I should check How query plan is getting executed. This will help in optimizing Sql queries.

I want to know what will be the answer for how to optimize SQL query in cache.

Thanks in advance!!

How Can I Do It (rebuild index) using ObjectScript?

Hey Developers,

Welcome to the next InterSystems online programming competition:

🏆 InterSystems IRIS Analytics Contest 🏆

Duration: August 23 - September 12, 2021

Total prize: $8,750

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:

• $TEXT
• XECUTE
• $XECUTE
• %Compiler.UDL.TextServices:GetTextAsString
• %Dictionary package
• Indirection

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?

New to IRIS. Installed docker container as per instructions. From my system I run:

# docker exec -it iris bash

and then try to start a terminal session, which fails

irisowner@2f54ebfbc52f:~$ irissession IRIS

<NOTOPEN>

How do I successfully start a terminal session?

This article explains how to use the InterSystems IRIS platform to write a basic IMAP client. First, we present an overview of IMAP, then we discuss the main IMAP commands and client implementation. Finally, we offer a simple use of this IMAP client on the IRIS interoperability application.

All French-speaking developers are friendly invited to follow a stream in the form of a journal.

Every first Thursday of the month at 12:00 (Paris time), we organize a 30-45 minutes stream on Youtube with the following format :

We invite you to the webinar "InterSystems Reports", on Tuesday, September 7th, at 10:00 (Moscow time). The language of the webinar is Russian.

After setting AllowedIPAddresses with a valid IP address

i get the following errors.

ERROR <Ens>ErrException: <READ>zOnTask+44 ^EnsLib.TCP.InboundAdapter.1 -- logged as '-'
number - @''

what am i doing wrong?

and question:

where in the message viewer can i see the source IP of the message?

Thanks

Hi Developers!

Here're the technology bonuses for the InterSystems Analytics contest that will give you extra points in the voting.

Adaptive Analytics (AtScale) Cubes usage - 4 points
InterSystems Adaptive Analytics provides the option to create and use AtScale cubes for analytics solutions.

You can use the AtScale server we set up for the contest (URL and credentials can be collected in the Discord Channel) to use cubes or create a new one and connect to your IRIS server via JDBC.

The visualization layer for your Analytics solution with AtScale can be crafted with Tableau, PowerBI, Excel, or Logi.

Hi,

I wonder if anyone could help me.

I'm used to writing Microsoft SQL database queries, but at the moment I am also trying to write reports on an IRIS database (used to be cache) in Microsoft BIDS.

My chief headache is parameters. They don't behave the "normal way" in BIDS, in that you can't rename them. Therefore, referencing them in the main code is a nightmare for me.

Say my report has two parameters. If i want to refer to both in a dataset, I have to list them in the order they are in the report and both by using a question mark, ie:

Team,

I am trying to use Visual studio code(1.57) for class development and for compiling classes (intersystems tools extension) . It works.

Now, i would like to use TFVC (Team Foundation Version Control) for source control.

I can see download option where i can manually download the Namespace as folder and classes as files.

Since whenever i save the file, it directly pushes the change to remote system. I am not sure where the local workspace is.

How to configure VS Code to track my changes and Check In / Check out the code.
