Get ready for a quick tech thrill! Last month, we dove into a time-sensitive project for the West Bengal state elections - a 5+ hour YouTube Livestream featuring real-time data in a dazzling design. This blog spills the secrets behind the scenes, from coding marathons to unexpected triumphs. Fasten your seatbelts - it’s a tech spectacle you won’t want to miss! 💻🌐🎥

Now, let’s get real. We had zero experience with a programmatically defined dynamic Livestream. None. Nada. Zilch. But hey, where’s the fun in sticking to the tried and tested?

The Stream Design

I already had the idea to add a dynamically generated state map based on the party’s colour with a lead on the constituency. This is what we (I and Karthik(Karthik Iyer)) envisioned our final design to be: read more...

Hold onto your internet connection because things are about to get interesting! I recently went on a scanning spree, unveiling the mysteries of my broadband peers and the results? Mind-blowing! 📡🔍 Ready to dive into the fascinating world of broadband revelations? Let’s roll! 🚀💻

My internet broadband provider is one of the popular Internet service providers in this region. I have been their customer for quite some time now. Though comments and reviews may point otherwise, I am satisfied by their service in my region with close to promised speeds mostly.

They use NAT and provide static IPs under the 10.0.0.0/8 private block, and if I am not wrong, this same subdomain is used in West Bengal’s operational area. As of this moment, they don’t block any cross-customer communication. This makes it possible to scan the entire network. And as I have mentioned later, this may be a security concern.

The masscan configuration used for the scan was: read more...

Ever felt like your internet journey is a little too exposed? As you surf anonymously, websites slyly snatch your public IP address, and your ISP lurks, peering into your every click. It’s the perfect stage for unwanted surveillance, with the potential to tweak your routing behaviour and block access to your favourite sites. Enter the unsung hero: DNS.

In this blog, we’re delving into the world of online invisibility. I’ll spill the beans on the latest tech tricks that can cloak your browsing habits from the prying eyes of ISPs, with a special focus on the wizardry of DNS. Ready to discover the secrets to a more private online experience? Let’s dive in!🚀🔍

Domain Name System

DNS is the phonebook of the Internet. It’s a global database of information about domain names. In simple terms, it helps convert medium.com into 104.17.31.52 which computer networks actually understands and can route your request to. read more...

Dive into my CSN-502 presentation delivered on 31.10.2020, where we unravel the intricacies of Network Access Control, with a special focus on Wireless Protocols. If you’re keen to delve deeper, check out the references for more details. This serves as your quick intro to the topic; the ppt is attached below. 🚀💻

Network Access Control

You must have heard that open and coffee shop wifis are insecure, and one must proceed with cautions. Now think about large corporates or campus networks. There’s a ton of stuff involved here which are private within the network and must be protected via access control and prevented from eavesdropping. Remember, a network is not just used for connecting to the internet. A single malicious device or some malicious programs in some innocent device can bring massive troubles to the network providers. All other stuff related to secure access management applies here as well.

So broadly, it is the job of the Network Access Control System to proactively detect and authorize the devices and put certain access control in place. It should also provide a mechanism to deal with malicious programs and actors acting with bad faith from within or outside the network. read more...
