Rapid prototyping of models with data is commonly practiced in Data Science to find the best fit models. Autoprototype is a python library that helps a user automate rapid prototyping and select the model hyperparameters. The user needs to pass the data and a few other parameters, and this tool will suggest:
a. the model structure best suited for the data
b. and the best hyperparameters for the models

ML Ops using SageMaker

This Experiment was carried out keeping in mind the complexity behind managing multiple ML Models in production, and a rationale behind how MLOps helps solve this problem. The code will help you to get started with implementing the MLOps process in AWS SageMaker. The implementation part can be done through the AWS console as well as the Jupyter Notebook inside a SageMaker Environment.

VirtueMart is an open-source extension component provided in Joomla for e-Commerce solutions. It has a few built-in payment gateway integrations, but sorely misses one with CCAvenue. This plugin bridges that gap by enabling the CCAvenue payment gateway integration for VirtueMart.

Loopback by default comes with Angular. This is a Loopback starter app if you want to use React with it.

We have also added our usual tools-of-the-trade like ESLint as a linting tool for javascript and eslint-plugin-react for JSX.

Pretty much in every enterprise application we build, we find ourselves needing a query / expression builder with a nice modern UI. Since we didn’t find a good open source component for this, we decided to roll out our own.

To make it reusable, we designed it in a manner it can be easily bolted on any DB or for that matter on an entity model in any language.

The schema/entity definitions are read as JSONs and the generated expression is also written as a JSON.

This project gives you a framework for setting up a hyperledger fabric v1.1.0 network on multiple VMs. We are using Vagrant with libvirt/KVM to create VMs. Other setups will work too, with some changes to the Vagrantfile.

NebTest will automate unit testing of Nebulas smart contracts. It enables you to:

• Automate smart contract testing on both testnet and mainnet
• Run test case with multiple test data sets at the same time
• Run test cases in a clean state, by deploying a smart contract before each test case

Our opinionated take on a MEAN stack (MongoDB, Express, Angular, Node) – modeled on Mean.io. We added a few handy features that we found ourselves repeatedly using. This comes from our deep experience in Node.js and related server-side JS tech.

Very similar to our Mean Idea. The only difference is that we replaced MongoDB with a Relational Database. Again, this is something we found ourselves repeatedly using, so we thought others might find it useful.

IdeaCrawler is a blazing fast, highly effective, flexible client-server crawling framework written in Go. We built it to perform certain tasks better than existing crawlers. Based on the tests we conducted, we found that our crawler outperformed Scrapy and several other alternatives, many times over.

In addition to the features you would expect from a regular crawling library, IdeaCrawler makes it very easy to do things like scaling across machines, crawling through VPNs, using cookies, using Chrome as a crawling backend, etc. It was written to act as a layer on top of a regular crawling library, with a lot of pre-written glue code.

This framework also allows users to isolate crawling to a dedicated cluster, while still being controlled from a central location.

This Apache Cordova Ionic plugin allows you to perform AES 256 encryption and decryption on plain text. It’s a cross-platform plugin that supports both Android and iOS. The encryption and decryption are performed on the device’s native layer, so the performance is much better. The entire operation is performed in the background thread.
