This is a post to link together various past/future ones into a single story. Understanding time series and various concepts like stationary, seasonality, trend and additive/multiplicative series. Forecasting with Facebook Prophet Forecasting with SARIMA Forecasting with LinkedIn Greykite Trying out Auto-ML with AWS and GCP Auto-ML with Azure How to understand and explain accuracy of forecasts There will probably be some more related posts over time and I will try to keep this index updated!

This story is part of a series. See this starting page for links to other lessons. In this lesson we will learn what is a NOT logic gate and build it with a transistor. In this circuit when you send electricity then the LED turns off and when you don’t…

We use a light sensitive component to control a LED and buzzer using a transistor as the switch.

This story is part of a series. See this starting page for links to other lessons. In this lesson we will learn about transistors and how they can be used as a switch. Please see previous posts for components we have already used in the past. The only new component…

This story is part of a series. See this starting page for links to other lessons. In this lesson we will create a circuit so that with a switch you can turn an LED on/off. As a bonus you can optionally add a component to control the brightness. For a…

This story is part of a series. See this starting page for links to other lessons. In this lesson we look at electronics around us and look at a bunch of components and try to name them. To inspire creativity and brainstorming in children begin by simply introducing the topic…

Previously I had used the public blockchain network to learn about Ethereum including deploying my own client. Essentially Ethereum and other such distributed ledgers (DLT) provide a replicated multi-node data stores. The special feature is that different nodes maybe owned and operated by different owners with no central control, and…

For permissioned blockchains, Hyperledger Fabric is one of the most prominent ones. Its backed by the Linux Foundation and open source, with good documentation so a good way to learn! At its simplest, any number of nodes referred to as “peers” may form a private network (invite only) and all…

As a first step I would suggest to read this prior post for some basics and using just your browser to get started. In this post I am using the Go lang based Ethereum client, geth, which is one of the most popular ones. …
