Quick, what's web3?

Web 1 — Everyone sees same content when they open a website. Servers just had filesystem and nothing else. Creation is limited to people with some learning curve. Ran from 1991-2004. Still a significant part of current ecosystem under CDNs. This is analogous to newspapers and other such media. We can

Platonic friendships

Platonic friendships

The boundaries are often unclear, and yet the intertwined lifestyles blur the distance, in friendship. There’s no exclusivity, no commitment, no priority. The existence of one another is celebrated, the joys and successes of others matter a lot but they’re not in our head when life replays. It’

Police and tracking mobile phones

Police and tracking mobile phones

Can anyone (police) track us through phone number? Thanks to crime patrol, this is a common question I get from people everywhere. So, let’s get to it. What is location? In the context, location refers to a particular latitude and longitude co-ordinates that’d geographically map to a unique

Homebrew as non-admin

Some compliances love complications. And one such, is restricting homebrew commands to admin user. As the package manager is crucial for several softwares, it's imperative to find a way to install it for local user without calling IT administrator. * To install homebrew in a directory called homebrew in home mkdir

Enforcing pre-commit hooks

Enforcing pre-commit hooks

When team works together, it's often natural and best to have pre-commit hooks that aligns style, and basic syntax checks before the code makes it to main branch. However, enforcing this often becomes a cultural topic, as people have to follow it by practice. Due to friction and time constraints,

Passing docker images without registry

I always wished for a way to quickly transfer a docker image from one machine to other machine, without the hassle of registry setup and access control. Until today, I was always sending (copy-paste) Dockerfile and building the image in destination machine again. Given the predictability, it works wonderful. But,

Ephemeral dev environments

Scenario is to create ephemeral dev environmnets in an AWS account with git branches. Note: We assume all dev environments connect to a single database instance. The idea is to create frontend (cloudfront+s3) and backend (ALB+TargetGroup+Ec2) and add respective DNS records. Frontend: AWS Amplify Console is a

What is a VPC

This post is for beginners. What’s a Virtual Private Cloud (VPC)? VLANs in networking terminology. It’s a private network in cloud where you launch our servers. VPC makes it appear as if all our servers and few cloud services are in a small private network, in complete isolation.

In 2019, I challenged myself in a rather unique way. I told myself I'd write stories behind shopping bills, using the whitespace efficiently. I wrote close to 300 stories in the entire year. Some of them are good, some were meh. The personal challenge improved my perspective to write instant

Trust, zero trust, mistrust

Edit: Previously mistrust is worded as anti-trust didn't convey the meaning of context appropriately. As per feedback, mistrust conveys it better. I've often wondered who I'd rather work with. People who trust, or people who have had zero trust? I've made quite a few career switches, sometimes left within two
