11 November - The curious case of DNS and wi-fi router
Like any one with an internet connection, I have a wi-fi router at home. And if you have seen my older posts you would know that I use a DNS based ad blocker that I run on my home network. The ad blocker runs on a raspberry pi and I use its IP as the DNS server/cache in my router. I wanted to run a DNS performance test and I used the script dnsperf to do that. It basically runs a DNS query on the list of provided name servers and measures the time taken. Below are the result when running the test with my router(with IP :192.168.1.1) as the DHCP and pi(host name: pi) as the DNS server.
20 May - My DNS stats
Like it or not humans are data generating machines. The generated data creats patterns and it may or may not be useful. In my case, I am running a DNS based adblocker that all my devices are connected to all the time. So I have a log of all my DNS requests that the devices/services/apps are making. In the past 30 days my 3 primary devices, a laptop, mobile and a tablet have made 270,563 DNS queries and the below is the split up of per device queries.
15 March - India AQI(Air Quality Index)
Dhuan is smoke in Hindi language. I started collecting the AQI data form Indian Government data site which provides the air quality data from variuos collection points from cities in India. The data is supposed to be hourly but I see that the updated data is only available once in every 3 hours. The data is collected via a python script that runs every 3 hours and stores the data into a pgsql database. I then use Grafana to filter the data based on the user input of state/city/collection point.

Namespaces are one of the fundamental building blocks for containers. According to Wikipedia a namespace is:
07 April - Adblocking in the cloud
I hate ads. Don’t get me wrong. I am fine to get informative/interest based ads. It becomes a bit hard when I am hit with a bunch of irrelevant ones and the amount of tracking that happens in the background. I initially used adblock plugins on the browser - which work fine to certain extent. But if I have to block it completely I have to use a Pi-hole setup.
