Hi everyone. I'm new to cache, and i was looking for a command who reads a .txt file and store the informations in variables. I've found on the documentation the EnsLib.SQL.SNapshot class, and, even if i'm not sure if that's what i need, when i run the code it says that the class doesn't exist, but i couldn't find the right superclass to extend.

Brainstorming the project we would build to showcase in the current female health themed InterSystems FHIR Contest, our girl band decided that we need to do something practical for the ordinary user and to solve some burning issues of the modern life. This discussion led to the idea of creating a project that will help women not to forget their health in daily grind - FemTech Reminder.

A few months ago, I read this interesting article from MIT Technology Review, explaing how COVID-19 pandemic are issuing challenges to IT teams worldwide regarding their machine learning (ML) systems.

Such article inspire me to think about how to deal with performance issues after a ML model was deployed.

Currently, the process of using machine learning is difficult and requires excessive consumption of data scientist services. AutoML technology was created to assist organizations in reducing this complexity and the dependence on specialized ML personnel.

AutoML allows the user to point to a data set, select the subject of interest (feature) and set the variables that affect the subject (labels). From there, the user informs the model name and then creates his predictive or data classification model based on machine learning.

Hi Community!

We try a new approach to the InterSystems Developers YouTube Videos called "Coding Talks"!

Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.

Check this video I made by myself participating in Advent of Code 2018 and coding with InterSystems ObjectScript in VSCode.
