Aindram Volume 01, My First Stint at AI Music Production

Aindram Volume 01 Cover

So, my first stint with AI music production has finally borne fruit, Aindram Volume 01.

Aindram is a collection of five poems I wrote on Indra, the Numero Uno God of the Vedas. I’ve published them in this blog too for reference.

For me, this project began as an experiment. What happens when poetry, Vedic thought, music, and modern AI music production come together? I wanted to take verses that originated in my own mind and give them a musical life, not merely as spoken poetry, but as songs with energy, rhythm, emotion, and a distinctly Indic character.

Indra has always fascinated me. In the Vedic vision, he is the mighty wielder of the Vajra, the destroyer of obstacles, the conqueror of forces that stand against the seeker, and a powerful embodiment of strength, courage, vitality, and victory.

That is the Indra I wanted to express through these poems.

Aindram Volume 01 is not an attempt to recreate ancient Vedic hymns. These are new poems, written in our time, inspired by the imagery, spirit, and grandeur of the Vedic Indra.

An interesting part of this process was using AI not only for the music, but also to help polish the lyrics. The poems were refined for poetic meter, rhythm, and their ability to fit naturally within the chosen raagas. This was an iterative process, where the original verses were retained while their structure and phrasing were refined to work as musical compositions.

The music was then created with the help of AI, turning those poems into something I could actually hear and, eventually, share with the world.

This has been a fascinating journey. There is something almost magical about writing a verse, shaping its mood and intent, and then watching AI transform it into a musical composition. At the same time, it has made me think more deeply about what the role of a human creator should be in an age where machines can participate in almost every stage of artistic production.

For me, the answer is becoming clearer. The human provides the thought, the intent, the vision and the soul. AI becomes another instrument in the creative process.

And this is only Volume 01. Find it on Spotify here:

I hope you enjoy listening to Aindram Volume 01 as much as I enjoyed creating it.

Indram vardhantu no giraḥ, may our songs grow Indra’s affluence.

Getting 401 unauthorized on Asterisk Login in spite of correct creds in PJSIP.Conf

Posted on by Sreekumar Kj / 0 Comment

Rest all being good, the issue was the credentials from chan_sip module (sip.conf) were being picked up.

Do these:

asterisk -rx "module show like chan_sip"
asterisk -rx "module unload chan_sip.so"
# persistently disable:
sudo sed -i 's/^load=chan_sip\.so$/noload=chan_sip.so/' /etc/asterisk/modules.conf || echo 'noload=chan_sip.so' | sudo tee -a /etc/asterisk/modules.conf

The Universe May Be Running at 10⁴³ FPS — And Planck Already Knew It

Posted on by Sreekumar Kj / 0 Comment

In 1899, Max Planck uncovered something timeless: the smallest unit of time that still has physical meaning.

We now call it Planck time: 

tP​≈5.39×10−44 seconds

It’s unimaginably short — far beyond direct measurement — but incredibly profound.

Because if we treat that as the duration of a single frame of reality, then we’re forced to ask:

Is the universe updating frame by frame?

Reality as a Causal Engine

Let’s follow that thought. If each Planck time is one “tick” of the universal clock, then the frame rate of the universe is: 

FPS=tP​1​≈1.855×1043 frames per second

Yes. Roughly 185 trillion trillion trillion trillion frames per second.

That’s not science fiction. That’s the math baked into physical constants.

And you heard that frame rate here first.

From Time to Space: The Planck Grid

It gets more intriguing when we realize that:

ℓP​=c⋅tP​

That is, Planck time multiplied by the speed of light gives us Planck length, the smallest measurable unit of space.

So we now have:

  • A pixel size: 1.616×10⁻³⁵ meters
  • A frame duration: 5.39×10⁻⁴⁴ seconds
  • A universal constraint: No signal or event can propagate faster than one pixel per frame.

Which is exactly what we mean by the speed of light.

But maybe we’ve been calling it the wrong thing all along.

It’s the Speed of Events

What we call “c” isn’t about photons. It’s a fundamental limit on how fast any event can ripple through the fabric of spacetime.

Like updates in a distributed system, or signals in a finite-element simulation, every interaction can only spread to adjacent nodes — one at a time — per frame.

In this light (no pun intended), the universe appears less like a smooth continuum, and more like a vast, local-update-driven causal mesh.

Planck gave us the constants. The frame rate, pixel size, and speed limit all emerge from them.

All we’re doing now is connecting the dots.

Why This Matters

This framing — no longer poetic but grounded in physical constants — has implications across:

  • Quantum gravity
  • Simulation hypotheses
  • Discrete spacetime models
  • Relativistic causality
  • The intersection of computation and cosmology

It might help explain why spacetime resists division beyond certain limits, why causality holds, and how the “engine” of the cosmos keeps time.

And just maybe, it hints that reality is more digital than continuous.

Next time someone says “the speed of light is the fastest thing in the universe”, you can tell them:

It’s not the speed of light.
It’s the speed of reality itself.

And it’s running at ~10⁴³ frames per second.

Intriguing right?
And yes, you read the FPS here first.

Heard of ScyllaDB? A Glitch Reveals My Data Stack’s Limits – And Our Response to it.

Posted on by Sreekumar Kj / 0 Comment

Deployed systems have a knack for humbling even experienced engineers. You trust your stack—until one morning it silently fails. Last week, during DheeGPT’s development, that exact scenario unfolded and forced us to rethink our infrastructure.

The Day Cassandra Let Us Down

We chose Apache Cassandra to power DheeGPT, our agentic AI engine for Indic languages. It had handled thousands of writes per second in our legacy and production systems — however in the development environment of our newest platform, a routine query returned zero rows:

  • The data was unquestionably in the table.
  • A secondary-index query returned no results.
  • A full table scan confirmed the rows existed—but the index was stale.

No errors. No alerts. Just missing data. Numerous minutes of debugging later, we traced the fault to Cassandra’s secondary index divergence. Invisible failures like this are unacceptable for real-time AI and and automations which are mission critical.

Where Cassandra’s Design Reveals Strain

Cassandra excels as a write-optimized ledger. Yet when you layer on dynamic queries and tight consistency, its limits appear:

  1. Secondary indexes can silently desynchronize.
  2. Rigid schemas force costly refactors if access patterns evolve.
  3. JVM GC pauses inject unpredictable P99 spikes.

As we built DheeGPT, these factors made us question whether Cassandra could sustain our reliability bar.

The Pivot to ScyllaDB During Development

Facing looming deadlines, we swapped in ScyllaDB mid-development. The transition was surprisingly smooth:

  • Zero code changes — Same CQL, same Spring Data drivers.
  • C++ Seastar lock-free, thread-per-core design.
  • Up to 10× throughput on identical hardware.
  • Sub-10 ms P99 latencies, even under traffic surges.

Though ScyllaDB launched in 2016, it still flies under the radar. License concerns and slower early evangelism held it back—yet today it’s a mature, high-performance alternative.

How DheeYantra Leverages Robust Infra

At DheeYantra, we build Dhee.AI Digital Employees that:

  • Power 24×7 customer support in Hindi, Tamil, Bengali, and more
  • Automate document processing and data extraction
  • Orchestrate workflows across enterprise systems in real time

For us, infrastructure reliability isn’t optional—it’s the core of our product promise. With ScyllaDB, we maintain sub-second response times at scale, reduce cluster size (and costs), and shift focus from firefighting infra to advancing AI logic.

Key Takeaways

  1. Revisit your defaults. Even proven tech can hide silent failure modes.
  2. Decouple API from engine. A compatible interface lets you switch back ends with minimal friction.
  3. Benchmark real workloads. Surface tail-latency and consistency issues before they reach prod.
  4. Invest in observability. Detect index divergence proactively, not after customers complain.

What’s Next: Digital Employees Powered by Indic Agentic LLMs

We’re excited to announce that next week we’re rolling out the new DheeGPT platform alongside our first Indic Agentic LLMs. These models will underpin Dhee.AI Digital Employees—reliable, multilingual agents tailored for Indian enterprises.

👉 Keep an eye on DheeYantra’s page for the official launch and demos.

👉 Reach out to explore how Dhee-powered Digital Employees can transform your workflows—whether in support, finance, HR, or field services.

Reliable AI starts with dependable infrastructure—and when it comes to reliability – we don’t “play”.
