HPC master's student.
I write about parallel systems,
simulations, and what runs beneath them.
I'm Rohan Sharma, a master's student in high-performance computing at TH Deggendorf. Most of my time goes into MPI, parallel algorithms, and simulation. This blog is where I write all that up. It's also where I say what I actually think about the infrastructure the world runs on, and who controls it.
I also think mass surveillance is one of the defining political problems of our time, and that you are being watched.
Why It Matters
Mass surveillance is not an abstract threat. It is live infrastructure, deployed right now, against you.
The Digital Panopticon
surveillance · chilling effects · self-censorship
Governments and corporations have built the largest surveillance apparatus in human history. Every call, message, location, purchase, and search is logged and analyzed. The goal is not to catch criminals. It is to have leverage over everyone.
When people know they are watched, they change their behavior. Free speech does not die in courtrooms. It dies in minds that quietly stop asking questions.
1.5M+
IMSI-catchers and stingrays deployed in cities globally to intercept mobile communications without a warrant.
Free Flow of Information
Knowledge should not be locked behind paywalls, controlled by states, or filtered by algorithms optimizing for profit. The free exchange of ideas is the oxygen of democracy.
Censorship, geo-blocking, and link taxes are modern book burnings.
4,000+
companies buying and selling your personal data (location, health, finances) without meaningful consent.
My Manifesto
- ▸ Mass surveillance must end. No government or corporation should have blanket access to the private lives of entire populations.
- ▸ End-to-end encryption is non-negotiable. Backdoors for governments are backdoors for everyone, attackers included.
- ▸ Information wants to be free. Scientific research, public knowledge, and historical records belong to humanity, not to publishers.
- ▸ Open source is a civil right. Code that runs the world must be auditable by the world.
- ▸ Whistleblowers are heroes. Speaking truth to power is never a crime, no matter how many laws are written to say otherwise.
Who is writing this
I'm a master's student who works on parallel systems and cannot stop thinking about power.
By day I work on high-performance computing: MPI clusters, simulation pipelines, squeezing every last cycle out of parallel hardware. It's honest, technical work, and I love it.
But the same systems that give us computational power (distributed nodes, centralized coordination, global networks) are also the substrate that mass surveillance runs on. You can't care deeply about how computation scales without eventually asking who controls it, and over whom.
This site is both things at once. The blog has write-ups on parallel algorithms, Minecraft biome generation, and whatever I'm currently obsessing over in HPC. This page is the other half: what I actually believe about the world that runs on all that hardware.

If you made it this far, thanks for reading. Head to the blog if you want to see what HPC and parallel computing look like when written by someone who also thinks about all of the above.
