Understanding Microservices: Exploding A Monolith

Understanding Microservices: Exploding A Monolith

Comments 0 Comment

This is a myth-buster exercise. When it comes to microservices, the talks and blogs around are riddled with fancy and scary terms. This presentation is takes a different take on it. Instead of learning the terms, we discover the solutions to various problems and then learn what those solutions are popularly referred to as. We go through the history of software architecture to understand how it evolved in the good old days. Based on which we draw some rules of…

Who do we write code for?

Who do we write code for?

Comments 0 Comment

Recently, while reviewing some code, I came across the snippet below. Now a keen mind can spot many issues with this. The ones I am referring to are something specific and relevant to the business though. The code is supposed to fetch all active clients, loop through, get job specifications from some DataSources defined for those clients, build a config object and return those values to calling function so that those jobs can be fired. Interestingly DataSourceInstance, DataSourceOriginConfig and DataSourceJobConfig…

Where Do We Go Wrong With Agile

Where Do We Go Wrong With Agile

Comments 1 comment

A few days ago I published this blog mocking the ‘Ceremony Focused Agile’ teams. But it is pointless to state what one thinks is not right, without also commenting on what one thinks is right! So let us do that today. Here is a conversation, which I am sure many of us have witnessed (or been part of): A: “I have assigned a ticket to you, what is the status of it?” B: “”Ticket, what ticket?” A: “It’s in JIRA,…

Revolutionising Agile With Head-Stand-Ups

Revolutionising Agile With Head-Stand-Ups

Comments 2 comments

So here’s a true story. I work with a normal sized team as per Agile/Scrum guidelines, about 8 people. We have our usual stand-ups every day, at about 10:30 in the morning. As a general rule, people have to join this meeting. Everyone speaks following the Scrum rules, just what is required: What I did, what I am going to do today and if I am blocked. And that’s it. Yet, our discussions diverge, others jump in to help whenever…

AWS Cloudwatch Log Scroller

AWS Cloudwatch Log Scroller

Comments 1 comment

This is a quick tip about a quick solution to a regular small problem! AWS CloudWatch logs are great, but the search feature on those logs is not. The search only lists the lines that are exact match to your search term. Usually you would want to see a few lines above or below the match as well! Not all logs are single line, unless you spend efforts in ensuring that there are no newlines in the content being logged…

Starting Your Own IT Business In India?

This is the Current State Of Processes Around It! I recently started working on a foreign software development contract. It seems that to ‘earn’ via such a contract, you need to have a business entity of sorts. I had to undergo a long, painful process riddled with unknowns and uncertainties to establish one and raise my invoices. Here is a brief of my understanding of the process and various norms and laws. I do not claim that the material below…

Mute Mic With Keyboard Shortcut On Ubuntu Or Linux Mint

Mute Mic With Keyboard Shortcut On Ubuntu Or Linux Mint

Comments 7 comments

Here is a quick tip for all the automation buffs like me. Turn your mic on and off with just a keyboard combo. I do all my work remotely. Which is also to say I have a lot of conference calls. And like you, I hate it when people do not mute their phones / mic on laptops when not speaking! (cue in the obligatory meme about not putting your phone on mute during a call!) I always wished for…

CIDR Explained in Layman Terms and Decimal Numbers

CIDR Explained in Layman Terms and Decimal Numbers

Comments 0 Comment

If you work on cloud it is likely that you have used those numbers and slash that follow the IP addresses. The documentation points to something called CIDR. It is said to be super helpful, and awesome standard adopted by internet that extended life of IP4 . But have you tried searching ‘what is CIDR’? It is all jargon, all of it. There is hardly any lay-man friendly explanation of the term. Even Wikipedia has managed to find a complex…
