Access to IRIS from Rust

What do you think If I will say you, that very soon you will be able to connect to IRIS from the application written in Rust.

What is Rust

Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but can guarantee memory safety by using a borrow checker to validate references. Rust achieves memory safety without garbage collection, and reference counting is optional. (c) Wikipedia

Using ECP across IRIS and Caché

Migration from Caché to IRIS can be quite a challenge if your code is grown over many years
and probably not so clean structured as you may like it. So you face the need to check your
migrated code against some reference data. A few samples might not be a problem,
but some hundred GB of data for testing might be.

A possible step could be to have your fresh code in IRIS but leave your huge datastore on Caché and connect both environments over ECP. I have created a demo project that gives you the opportunity to try this based on 2 Docker images with IRIS and with Caché connected over ECP.

Hi Developers!

Thank you for using ZPM Package Manager and contributing more and more useful packages to the public registry!

But as you already aware ZPM packages are always deployed with source code.

Do you think we need to add the option to deploy without source code - e.g. if you want to deploy a commercial package?

Will you develop commercial modules if there will be an option and deploy it with ZPM?

How do you deploy commercial applications today?

Fraud Management with InterSystems IRIS

Organizations around the world lose an estimated five percent of their annual revenues to fraud, according to a survey of Certified Fraud Examiners (CFEs) who investigated cases between January 2010 and December 2011. Applied to the estimated 2011 Gross World Product, this figure translates to a potential total fraud loss of more than $3.5 trillion (source: https://www.acfe.com/press-release.aspx?id=4294973129).

What is accuracy, accuracy, recall

Accuracy rate is a measure of our prediction results, and it is a measure of how many of the predicted positive samples are actually positive.
The recall rate is for our original sample, and it shows how many positive examples in the sample were correctly predicted.
Accuracy = Predicted correctly/All
If we want to be able to retrieve as much content as possible, this is the pursuit of "recall ratio", namely A/(A+C), the bigger the better.

Hey Developers,

Enjoy watching the presentation of the IRIS-REST-API-DATABASEMANAGER app that allows you to create persistent Tables and Data in InterSystems Cache Database:

This is the first InterStstems programming contest that we participated in! Come check out and vote for us!

The overbooking management system combines the unique conditions of the hotel, such as room prices, order channels, customer needs (etc...). System uses machine learning algorithms (such as: KNN/ES-RNN...) to accurately predict the daily no-show and occupancy rate of the hotel, and further combines with the revenue equation to find the best largest room sales volume, which can significantly increase the hotel marginal revenue.

Good day, developers!

The "apptools-admin" project is not only a set of tools for the administrator, but a platform for the rapid creation of a prototype of any solution.
For example, Photo Album, Music Player, and Personal Library all come together in a user-friendly treasure chest design.

Load http:// your-host:your-port/apptoolsrest/a/infochest

Change the path to your treasure files and start viewing, listening or reading from any convenient device: desktop, tablet or smartphone.

Random Read IO Storage Performance Tool

New Tool Available

Please see PerfTools IO Test Suite for a later version of the Random Read IO tool.

Purpose

This tool is used to generate random read Input/Output (IO) from within the database. The goal of this tool is to drive as many jobs as possible to achieve target IOPS and ensure acceptable disk response times are sustained. Results gathered from the IO tests will vary from configuration to configuration based on the IO sub-system. Before running these tests ensure corresponding operating system and storage level monitoring are configured to capture IO performance metrics for later analysis.

I have 2 instances of Cache, one of 2010 and the other 2016. On both I have created a SSL Configuration with same name.

When I connect to a SOAP Service Client from Cache 2010, I get the above error.

If I connect from Cache 2016, the connection get through.

How can get more details of the error in the Cache 2010 instance to be able to fix this issue.

I have enabled the SOAP Log and it does not give much of details.

Regards

Anil
