Blog Posts

Today's session was led by Jatan where we discussed what is the most basic requirement for a blog. These are my notes about the session.

When I need to do presentations at work, I naturally reach for Emacs. My presentations include diagrams, code snippets and running small shell blocks. I found that Org Mode with Babel is the perfect fit. In this post, I'll describe my presentation stack based on Org mode.

In the last post, I covered the basics of [Lambda calculus](/blog/lambda-calculus/) and its lack of built-in data types. Church encoding defines a way to represent data types as pure functions. In this post, I'll explore church booleans and control flow, and implement them using Python.

Many modern programming languages trace their roots back to Lisp, which in turn builds on ideas from lambda calculus. In this post, I explore the core ideas of lambda calculus.

Comaps is an open-source navigation app that works completely offline. With Comaps, you can track your real-time location in airplane mode—just like an in-flight map, but on your own phone.

Emacs supports editing remote files using the Tramp package. Emacs transparently handles the remote files based on the special path prefixes specified, so the experience is similar to operating on a local file. Tramp uses a remote shell underneath to access remote files. In this article, I'll talk about how to extend Tramp to support custom Methods to access remote files.

In this article, I'll talk about a pretty old RPC Protocol, XMLRPC. It is over 20 years old now and, it is mostly associated in legacy systems. I'd have never come across it if it wasn't for ROS. ROS 1.x still uses XMLRPC for all of its communication. So, I decided to read out the protocol specification.

ROS is an acronym for Robot Operating System, but contrary to the name it is not an operating system. Instead, ROS is an open-source framework for building software for Robots. I got introduced to ROS in my current company which is a Cloud Robotics startup. In this article, I'll give a general introduction to ROS based on what I learned.

In this article, I'll share my thoughts about Selfhosting.

I’ve been a happy user of Bitwarden for over a year. In this article, I’ll talk about an alternate implementation of Bitwarden and my experience with it.
