GPSLogger wth CouchDB 1

GPS Logging using GPSLogger and CouchDB

One of the valuable features of Google maps app is GPS logging. It keeps track of where you have been so you can take action if required later. I wanted an open-source, self-hosted version of that.

SDR on Android Phone

I have been thinking about running SDR on Android for some time. So I did this week. The setup is useful for “showing” radio waves to kids and adults. It also makes sense to see it when you want to debug wifi channel or other radio issues at home.

Communicating with Minetest Server Using APIs

I have been playing Minetest for a while now, mostly in creative mode. Recently I wanted to control it programmatically. So I started looking for ways to do it. I found mineysocket mod, which gives remote access to Minetest server over a network/socket API. There are wrappers available for various languages, including Python.

Programmatically Creating Embulk Configuration Files

Embulk needs a YAML file configuration for each data load. It’s a simple format, very human-readable. But there are cases where I want the YAML files to generate dynamically. Embulk does support an experimental feature that involves liquid templates. But my team is well versed in Python and Jinja2. Hence that is what we use.

My Boring Yet Modern Data Stack

We have a data stack that we have been using for years now. We have used it with medium to large customers, and they have worked very well. The goal has always been simple, stable, composable tools that can be used on the developer’s machine and scaled to work with massive data on production. You can self-host them, host them on the cloud, or get managed services based on your need.

Very similar to my web stack. It’s called “Boring” not because it’s dull but because there are minimal unwanted surprises. So my current stack for data looks like this. This stack is both “Modern” and “Boring.”

Embulk for extracting and loading data

Embulk is a bulk data loader. It helps transfer data between different types of databases, storages, file formats, cloud services, etc. It’s like a Unix tool. It’s simple, robust, and works well with other tools.
