Instead of focusing on the number of lines per method, I like to focus on the number of local variables per method and try to reduce them. #programming

Sharing of common code / state and sharing of common interface / type are two different things. Common code sharing can be achieved with Composition or class inheritance (prefer composition). Common interface (substitutability) can only be achieved by (interface) inheritance.

Reading a new #code base with depth first approach goes against the idea of Abstraction. Breadth first approach for understanding a new code base is a better approach. #programming. .

We've been running a learning competition called "Big-O" at work. This time it was about building a high-performance key-value store. Here's the problem statement bit.ly/3jokUIa created by Priyank Gupta.

Many developers severely underestimate the complexity involved with microservices. While there are many books/articles about the topic, they often miss sharing intuition about the huge level of complexity involved. Will try to share my understanding in this thread...

What is your definition of the duplicate code? Is it the code that looks identical/similar now? Or Is it the code that looks identical now and also changes together for the same reason? If it's the latter then what is the best time to remove the duplicate?

When people share how crypto can bring payments to underserved communities, I ask them if they heard of UPI which did this - but without blockchain. UPI has no fees, is secure, works offline as well and 6 years after launch accounts for 60% of retail payments in India (!!)

Flow in #softwaredevelopment can be increased by minimising the work items being blocked or queued and ensuring work items are being worked on continuously to completion.

In other words… Identify and focus on the few major factors that affect a problem… and ignore the minor factors. In most cases only few things are disproportionately important. Ignoring this leads to sloppy thinking.

The Single Responsibility Principle (SRP): Gather together those things that change for the same reasons and at the same times. Separate those things that change for different reasons or at different times.

The modern Kubernetes cluster hosts a range of services. An URL masks the complexity of microservices. What lies beneath the hood? This Devday join Prashant Kalkar at our Pune office or PUN - tinyurl.com/2p8p9vu4 CHE - tinyurl.com/3twaswun BLR - tinyurl.com/2p8mbpj5
