Device Discovery in MQTT: Using Retained Messages as a Service Registry

Mon, 20 Oct 2025 10:35:07 +0530

When you have some number of IoT devices connected to an MQTT broker, one of the major concerns we had is - how do we know what devices came online, what topics they publish to, and what are its other params (device details). Most solutions involve maintaining a separate device registry database. But the idea here is to use MQTT broker itself as a device registry.

In typical MQTT deployments, you need to maintain device inventories separately: a database to store device metadata. Still, at this point, the path to write this info to the database write/read has to be created.

User Attribute-Based Authorization in Multitenant Apps - Django-tenants

Tue, 15 Apr 2025 11:05:07 +0530

This article assumes you’re using django-tenants for schema-based multitenancy (separate PostgreSQL schema per tenant). The authorization pattern described here works specifically with django-tenants’ schema_context() approach. If you’re curious, read the AWS cognito part as well.

The Problem

When building a multitenant application with django-tenants, we needed to control which PostgreSQL schema each user could access. Each tenant has its own isolated schema, but we needed a lightweight authorization mechanism to ensure users could only access their assigned tenant’s data.

Django (DRF) Serializers To Handle Nested JSON data

Fri, 25 Oct 2024 00:00:00 +0000

I have been dealing with a lot of JSON data more than ever before. All of the data are coming from a Webhook provider upon certain events. One of the things I was not comfortable with was the nested JSON structure until I found there is a clean way to solve it. Our Django app uses Django REST Framework (DRF) and relies heavily on its serialization capabilities.

What are we going to see

Looking at the data (JSON/dict)
Looking at the model where the data is about to be stored
Writing DRF serializer to handle the nested data
- More details of how its done using to_internal_value()
conclusion

A sample JSON data for context

This is a webhook event when a charging session is started and stopped. Looking at the JSON (data) itself - it has a max depth of 5.

Python - A Clean Way to Traverse Nested Dict/List

Wed, 28 Aug 2024 08:03:57 +0530

I had to work with some complex structured JSON responses having multiple levels of nesting. The issue has always been that the API would return nested JSON where I have to walk different levels to get data by using x.get('y')[0].get... chains.

For this very reason, I was looking for an optimal and efficient solution so that at least I can avoid calling get() many times.

The Problem

Let’s say you’re working with user data from an API:

Auth0 as OpenIDC broker in AWS Cognito for AzureAD multi-tenancy support

Sun, 24 Mar 2024 00:00:00 +0000

If you read the previous article OAuth using AWS Cognito, then you should be also reading this. I’m writing this article after a month of this very story. But I believe I won’t miss much.

SAML, OIDC setup and overview

If we look into the out-of-the-box social identity providers , there are few. If we want to add Microsoft/Azure, that would be done via SAML or OpenID connect.

Due to our client requirement, we started working on integrating Azure (now Entra) into Cognito via SAML. In Azure, to setup SAML, we start by creating an Enterprise Application.

Django OAuth setup with social login, AWS Cognito, GitHub - Full story

Thu, 25 Jan 2024 00:00:00 +0000

I spent some quality time researching about OAuth in Django. Tried more than 3 packages. Well, it was not just about just installing something and expect everything to work. There was some tinkering which i think i did well. Therefore, this some part of this blog might also help in your case i guess. I will be also uploading a YouTube video of the same, if i do, you can find the video at the bottom of this page.

Global variables in AWS Lambda are dirty!

Wed, 01 Nov 2023 00:00:00 +0000

Hello everyone, I know that it has been a long time since i wrote a post. I hope every thing is going well with you. I always wanted to consistently write here. But lets see if I can make it possible sometime soon :)

What is this post about?

Today, as usual i started off the job in the morning. I’m at a juncture point of building a part of the project. There again, we need yet another micro-service. So, I started writing a piece of script (Python) that needs to be deployed in AWS Lambda. This usually should only take couple of hours, max. But, after that i wrote it, I realized that, half the time writing the script was spent on debugging an issue that i did not even understand how/why it happens. After finding the why/how, I thought it’ll good to share it here and someone will find it useful on the way.

Some thoughts on working 'Smarter'

Sun, 28 Aug 2022 00:00:00 +0000

Let me start with a simple quote:

“The only way to do great work is to love what you do.” — Steve Jobs

The best way to learn deeply is to do what you genuinely enjoy. Whether it’s software dev, farming, carpentry, or any other task — if you like it, you’ll enjoy doing it and you’ll learn from experience. Our minds naturally grasp the things we care about. Put in more effort where your interest lies, and you’ll get better. I say this up front because it’s something I’ve always told myself.

what does the Bible say about jobs 👷‍♂️

Sun, 31 Jul 2022 00:00:00 +0000

Are you a wagie? Most probably you are unless you have some passive/active income from your product.

Over the past decade, I’ve seen many people jumping from a mechanical engineer role to a software field. Reason is quite obvious. I don’t want to tell you that software industry now provides more employment. It’s really good if you enjoy it. What if you are not interested in but still working on it.? I don’t know how it feels like considering money comes on top of it as a reward.

Introduction to Termux-API and script automation 🧑‍🔧

Fri, 01 Jul 2022 00:00:00 +0000

Welcome back to yet another amazing article. By the way, have you seen the new video uploaded at YT? This article is about about the same. Now, If you think about why do I write this blog after creating a video - well, a video is mostly a quick take (for me). We miss many things. Writing a blog mostly explains everything.

Yes, now you have an idea about what I’m talking about. It’s about Termux-API and how we can make use of them in real life applications.

I made my Resume from Markdown with CSS styles.

Tue, 07 Jun 2022 00:00:00 +0000

Hey all! welcome back to another article. I hope your week is going well. About me, I’ve had few wonderful stories to share with you, which is about a job interview that i had applied for. In the final round(HR)the story went twisty in many ways. So, I’ll share it another day.

I’ve been so concerned about editing my resume. Up till last week, i was using Canva website to make my resume. When i think about it now, feels like an extreme normie.

The movies promote cigrates with lung cancer notice.

Sat, 28 May 2022 00:00:00 +0000

May be I’m too distracted. But, Fu*k any movies, series or any such crap showing smoking and shamelessly says that it causes lung cancer.

I’m not those “Social activists” or any such people who would raise arguments on any things others do. I don’t involve in anyone’s privacy. Because I’d like to give them their own space. But things like addiction is something someone don’t want instead mindlessly doing it.

A random story..

Wed, 25 May 2022 00:00:00 +0000

The school 🎒

Back in 2015-18, writing blogposts was all about curiosity. I still don’t know how I was so boosted at that time. I was at 10th standard. Didn’t own a computer at that point. Parents didn’t like me doing something on computers. And had have a valid reason to block me from using it.

See me.. I was very good at studies from 3rd grade to 7th grade. After that, I turned out to be an average. It wasn’t intentional at all. All happened unknowingly and I became more aware of it after each test papers. Fast-forward! what would you expect me at 10th grade? I was even slipping down from the average position.

XREP needs more time to release

Mon, 09 May 2022 00:00:00 +0000

As you already know about XREP, while some others have used it as testers. I was expecting the release of XREP by the end of this month. But It’s not going to be the case. As of now, I’m in the middle of many things and can’t give proper focus to it.

The last commit was on 5th of May. There are not many things left. Infact the Python-re version is making some headache to me.

Why Comments Are Disabled on My WebSite

Sat, 07 May 2022 22:24:43 +0530

This is intentional. If you guys know me from the start of the time when I had “techcraft.tk” (my old tech blog), it was roughly around 2016-2018, but later on, i had decided to change the domain. The point is, for each post, i saw many spam or rather irrelevant comments which makes me few people are so dump. They might be putting comments on “crypto” or “pay me I’ll hack social accounts…so on..”

I Left Blogger After 6 Years

Fri, 29 Apr 2022 21:37:37 +0530

It has been more than 6 years since I started my Blogger journey. Blogspot indeed was/is a good way to start any static website from scratch and get it done in minutes. It felt very convenient for me over the years and also the settings and configs are also very intuitive.

Not so long ago, I saw a cookie pop-up on my blogger which I did notice when someone told me. I was sure that I did nothing to show a cookie banner. Idk why but, it kind of made me think “this is not my stuff and I do not fully own it”. And it was one of the many reasons I wanted to switch. I had some political opinions which I wanted to share but afraid about Google policies applied to Blogspot. Over the time, it really shook me and made me think “why do I use Linux, FOSS, etc..?” That’s when I really took the time to switch. I backed up all my posts from Blogger since 2016 and converted it to Markdown and made a video on YouTube about the process just in-case if someone wants to switch immediately without much research.

I love flask ❤️

Fri, 04 Mar 2022 06:54:00 -0800

The title is obvious. Everyone loves Flask as a small web framework. As of now, all my projects are built with flask. Including b3nsh4.tk

Few have asked what did i use for XREP. Yes, it is flask again. Idk why it’s so easier to get started with something and can’t be more easier.

For me Django is framework which works out of the box and has many more features. But if the idea of our application is complex at the backend and less fancy frontend with no db, login.. flask is the option.

Discrete mathematics is awesome?

Wed, 12 Aug 2020 03:44:00 -0700

Yes, after an year, I finally decided to take Discrete mathematics again as a part of my university. Tbh, I didn’t really enjoy it when I came across it a year back. But, now I feel like it’s somehow helping me to think in a logical way. And, I also found a good playlist for learning it. If you ever want to jump in to this business, this will help . That’s the playlist. I thanked him via twitter for this. If you are bored, I think this will fill / blow your mind. Hmm.. if free take a look. Btw, I’ve few things to say about YouTube and why I might leave it soon…

Downgraded to Android 7 (for bootloader unlocking)

Upgraded to Android 9 (after unlocking)

Flashed twrp (shitty thing I’ve ever done)

Rooted with magisk.

If your stock recovery is overwritten, sadly, you cannot install any OTA. Can’t you do ever? Well, yes you can. But, you have to;

Downgrade to Stock (7.1)

Unlock bootloader (if needed)

Install all available OTA to Android 9 including July security patch

Persistent start is important!

Tue, 28 Jul 2020 22:32:00 -0700

When I started blogging, I was changing my domain frequently. I wasn’t satisfied with any. Finally, I fixed to go with techcraft.tk domain. And, I used it for very long time. Made few pages to promote that blog. I was passionate about blogging at that time more than now. For some reason, I couldn’t continue doing blogging. So, after very long time, here I’m am. Changed domain again to bensh4. I really liked this username and I sorta wanted to make this everywhere. That’s why I again changed to bensh4. I was worried about AdSense because of this continuous changing. Because I stopped blogging then, I didn’t bother about that much. My advice for a new blogger(or any starter) would be like; You have to be really sure about what you’re doing and will do. Choose something (username for eg:) and don’t tend to change it.

I learned not to run my nginx as root

Tue, 28 Jul 2020 04:39:00 -0700

I’m mostly using Android to do my daily stuffs than my laptop. But when I start to use laptop, I’ll rarely use my phone. 🙃

I was running nginx in Termux on port 80 some reason. Since SeLinux feature is set as permissive, it’s not stopping me from doing that. So to start server with that port, I must be root. So, I start nginx as root , which means now it has the role of root. It’s like a real root user in my host which can access my host files and what not. So, atleast a docker is more appreciated to run it. Or more abstractions are possible via Selinux, Apparmor or Firejail those can have custom profiles for more security. And, I found a good article > here <. It’s a Medium article.

Tue, 28 Jul 2020 00:00:00 +0000

I can post my thoughts via this blog even if I leave that platform. But, I’m only thinking. But, I’ll leave one day for sure. Because, think for a while, “why do we need that platform?”. For sharing our thoughts and ideas? That’s why we can have our own blog. That’s how I’m believe. Back in the days, it was awesome to see many blogs like people writing their daily diary . Now everybody is via twitter and others. Well.. there are many things to say. May be my first Episode of podcast will be subjecting this.

Yes,its possible. Terminal can also these kind of stuffs. It can also intercept webpage elements. Same as like a browser could do in a PC.There are also some other easy way to get those. Simply by going to validate.w3.org

An other alternative way is by downloading apps like ‘VT Source Viewer’.

We are using ‘wget’ command. And if you are unaware of wget command. Just open terminal and type

Android comes with a different architecture.

Android library consist of

NOTE: We are not deeply diving into exploit SQL databases. This is just a tutorial on how you can access the databases.Anyway,I will prepare a new article on how to exploit SQL Lite databases on Android.
