I have been playing with RaspberryPI for a while. There are several project I tried to do with RaspberryPI. These boards play a significant role in my home lab for different experiments like Docker Private Repository, Media Server, Ad Blocker with pi-hole, Secure Proxy for anonymity, secure network access with VPN, Home Security Camera/Surveillance, Data Collector or scraper etc. But This time, I did buy a “DHT-22” sensor for monitoring room temperature and humidity. Humidity is my main concern and wanted to see how it fluctuates.
So, my main plan was to get a DHT-22 to connect properly

I have always worked with Linux Systems and thus Bash was my go to tool for some specific tasks. But now I am much more aware with Python than Bash as it does give me better grasp on things. I am not saying that for server scripting, Bash can not do some tasks. It can be used in a vast area of things to solve. But I am now comfortable with Python more.
Recently, I did stumble upon of a task that was related to comparing two huge CSV files.

I am recently playing the role as an SRE and that is why I have to deal with a lot of servers. Not only cloud once or clusters but also bare metals as well as Virtual Machines. For more systematic environment preparation, I have Gitlab pipeline. But for basic tasks like change the config on demand or check a specific directory or search something or any other unpredictable or repeated tasks, I need Ansible for better grasp from my local machine or Bastion server. So, what do I have to do?
- Create an entry to the .ssh/config file
- Create an entry ansible host file as inventory
Repeated tasks? For me, yes. I needed to manage these. So, created a python script

Containerization gives us many benefits from packaging to distribution and others. Thus, Docker is widely used as a containerization tool which is designed for running specific tasks and processes, not for hosting operating systems or like other virtualization tools like VMWare, VirtualBox etc. You create a container to serve a single unit task. Once it completes the given task, it stops. The container life-cycle depends on the ongoing process inside of it. Once the process stops,

I have been working with redis and python for sometime. It is fun to play with python and redis. There are so many things can be solved by redis.
- Session persistency
- Volatile Datastore
- Job or Message Queue
And many more. But recently I was thinking about using it as main database. I am not yet sure what kind of problem I might face or what things to optimize when it is about scalability or reliability. I will for sure share my experience.
Here I want to talk about –
