Borrowing simple math concepts from trigonometry, calculus, limits, curve fitting, probability theory, linear algebra, distributions, etc. this paper highlights how they can be used in almost every aspect that a programmer has to take into account depending upon how experienced they are. A successful programmer always relies on back-of-the-envelope calculations and the paper highlights them too.

Borrowing simple math concepts from trigonometry, calculus, limits, curve fitting, probability theory, linear algebra, distributions, etc. this paper highlights how they can be used in almost every aspect that a programmer has to take into account depending upon how experienced they are. A successful programmer always relies on back-of-the-envelope calculations and the paper highlights them too.

The paper sizes a thread pool using calculus, uses Fourier transform to help in troubleshooting a tricky issue, assesses chances of request landing on some faulty node behind a load balancer, compares algorithms runtime complexities using limits, optimizes memory utilization, computes rate change in message arrival, understands how different queues are loaded after state transitions from one to another, etc. all based on my experiences using simple math over the years.

My take on YARN and how can it improve further to moving from being a great framework to being a 'near-perfect' framework.

Building distributed architectures is not easy. Migrating application to cloud is even tougher. Plus, the pressure to contain costs adds to the challenge.

The paper discusses design strategies to be incorporated in application architecture which contribute to saving on costs on cloud. Approaching costs from an application architect point of view, the paper discusses techniques in building cost-effective architectures.

A comprehensive coverage on Internet of Things (IoT). What makes IoT so formidable is its ability to transform and redefine our planet in unimaginable ways.

The paper provides explanation of some of the most influential technological break-through such as advances in semiconductor industry, cloud computing, big data and machine learning. The paper attempts to also describe challenges that industries will face which include security of data, network limitations, storage aspects ranging… Show more

This article discusses at length commands and tips which can help developers appreciate the science behind troubleshooting application. It explains how root cause analysis can be done in a methodical manner and how a good hypothesis is formed.

The paper looks at aspects such as garbage collection, TCP level debugging, CPU utilization issues, concurrency issues, main memory swapping/ thrashing, application crashes, virtualization costs, etc.
