MLFlow is an open-source platform for managing your machine learning lifecycle. You can either run MLFlow locally on your system, or host an MLFlow Tracking server, which allows for mutiple people to log models and store them remotely in a model repository for quick deployment/reuse.

In this article, I’ll tell you how to deploy MLFlow on a remote server using Docker, an S3 storage container of your choice Minio or Ceph and SQL SQLite or MySQL.

Deploying a machine learning model built with Apache Spark isn’t as straight forward as the deployment of a PyTorch model or a TF model. Especially when you’re planning on having a REST API for inference requests. One way of going about it is use MLeap, but that would require modifications to training code, as MLeap relies on it’s own serialization.

The best approach that I’ve found is using Openscoring and PMML (Predictive Model Markup Language). PMML is a an XML based markup language that stores your predictive model and openscoring is used to create the inference REST API. The steps for doing so are as follows:

Microsoft has been doing great stuff for years now, and WSL2 (Windows Subsystem for Linux - 2) is everything that I personally neeeded to feel completely at home as a developer in Windows. WSL2 allows you to run a full fledged Linux kernel with greatly improved IO and support, as compared to WSL1. WSL2 connects flawlessly with a Windows installation of Visual Studio Code and supports Docker natively. In short, your Windows setup would serve you well in your development endeavors.

In this article, I’ll discuss how to get WSL2 up and running on your system along with an integration with - Windows Terminal and Visual Studio Code.

COVID-19 has created many problems for the government which are solvable through technological intervention. This here, is a system to manage the daily updation of patient health and current symptoms via call operators for those in home isolation. I worked on this project on a volunteer basis for urgent deployment. The project is built entirely in Flask with Bootstrap 4 for frontend styling.
This system has the following features:

This post builds upon the guide to developing projects in MERN stack that I posted a while back, you can find it here.

Heroku probably has the best free-tier service out there for hosting MERN stack web applications. Though it requires certain non-intuitive settings before you can go about deploying your app. This article will guide you through the process of deploying your web-app on Heroku.

• We would be deploying the server and the frontend on the same deployment instance.
• The database being used here is MongoDB Atlas.
• This deployment uses npm instead of yarn for deployment.

Around a couple of weeks ago, I found out that the district administration of South Delhi, like governments all over the world, are struggling to find a strong technical solution to contain the COVID-19 pandemic. Especially in Delhi, with cases surging, it was becoming increasingly difficult to create containment zones manually by looking at addresses of patients when thousands of cases are coming in everyday.

I came up with a better way of doing that, and with the permission of the District Magistrate of South Delhi, coded and deployed my solution built on their database. The solution was well received by those in charge of containment zones and is now live.

In this article, I’ll briefly explain my approach.

My dad works for the Indian Railways, and when special trains started running to transport migrant labourers during India’s response to the COVID-19, he discussed the logistical issue of managing police escorts on these trains and coordinating with different government agencies.

The usage of the global keyword in pythonic development is discouraged, and for good reasons. It often becomes troublesome to keep track of global variable usage and assignment as the code file grows, and is almost impossible in very large code files. This creates issues in debugging, reading and understanding the functionality of different code blocks and understanding the workflow of the application under consideration.

MERN Stack implies the usage of the following technologies for full stack development:

• MongoDB
• ExpressJS
• ReactJS
• NodeJS

In this post, we’ll go through the basics and logistics of getting started with MERN development. I’ve limited the content of this post to the bare essentials, while learning MERN development from FreeCodeCamp. Resources for where are :

• Article
• Code
• Video

Heroku is a popular application deployment platform with a functional free tier of services, and Flask is populalar application development micro-framework in Python. The Heroku-Flask environment is one of the quickest ways to deploy a small application for testing, yet sadly, I did not find a single tutorial that covered all aspects of the deployment process without leaving room for a whole bunch of errors.

Hence, this guide.
