Hi everyone,

I recently finished building **Project Shuzi (v8.4)**, a deterministic state-machine and hardware-isolated MMIO quarantine engine designed for constrained edge environments. I am opening **Track A (Public Black-Box CSV Challenge — No NDA Required)** to invite external engineers to test the parser against hostile 6-column ASCII CSV payloads.

* **Note on Source Code:** The core enclave engine is proprietary due to pending patent protection; this is a black-box stress-testing challenge.

* **Submit Your Payloads:** Share your fuzzing scripts, Gist/CSV links, or use the README intake channel to receive a full telemetry report.

Throw your worst edge cases at it—let's see if anything gets through.

For decades we've treated transport interruption as something applications must recover from.

TCP reconnects.

QUIC reconnects.

Applications retry.

Sessions are rebuilt.

I've been exploring a different architectural direction.

The idea is simple:

Session identity should not be tied to a single transport path.

Instead, transport becomes replaceable while the session remains authoritative.

The project I'm working on is called VRP (Veil Routing Protocol).

The focus isn't throughput or latency benchmarks.

The focus is:

• session continuity

• authority preservation

• replay resistance

• deterministic recovery

• verifiable execution

I've built a prototype and validated it under path migration, packet loss, reordering, replay scenarios and runtime invariant testing.

I'm not asking whether you think VRP is "better."

I'm interested in a more fundamental question:

Do you think session continuity belongs inside the protocol itself, or should it always remain the responsibility of the application layer?

I'd really like to hear arguments from people working on distributed systems, networking and protocol design.

I've been deep-diving into database internals recently and I'm convinced we can do better than the standard interpreter model for query execution. I’m starting a project to build a hybrid In-Memory/Storage engine where the queries are compiled directly to machine code using LLVM.

I know PostgreSQL is the king (and I love it), but I want to see how far we can push performance with modern compiler tech.

The Tech: LLVM, Go/Rust (still deciding on the core bridge), and a focus on keeping it lightweight.

I'm a software dev looking for anyone who wants to nerd out on systems programming, compilers, or storage engines. Even if you just want to contribute one line or give me some feedback on the IR generation, I'd be super happy.

DM me if you're interested! I don't have a repo link yet as I'm just cleaning up the initial PoC, but I'll share it with anyone who reaches out.

I've created a PRNG lib w/ raw SIMD intrinsics (both NEON and SSE). It really feels good to achieve nano seconds performance as a beginner in systems engineering.

My attempt at a complete high-frequency trading (HFT) pipeline, from synthetic tick generation to order execution and trade publishing. It’s designed to demonstrate how networking, clock synchronization, and hardware limits affect end-to-end latency in distributed systems.

Built using C++, Go, and Python, all services communicate via ZeroMQ using PUB/SUB and PUSH/PULL patterns. The stack is fully containerized with Docker Compose and can scale under K8s. No specialized hardware was used in this demo (e.g., FPGAs, RDMA NICs, etc.), the idea was to explore what I could achieve with commodity hardware and software optimizations.

Looking for any improvements y'all might suggest!

Everything I know about (TCP) congestion control in data center is quite old, having covered the basics in an undergraduate computer networking class. I also realize the state of the art has moved along quite a lot -- modern networks have multiple links, different topologies and load balance across them, ECN is more common place and algorithms based on BW-delay product, explicit admission control and RTT measurements are commonplace. Finally, I also realize that there are schemes and approaches that I probably don't even know of given I haven't followed this field closely.

There seems to be a complex play between workloads, desired properties, network topologies and algorithms and I'm looking for anything a primer/summary/lecture notes/class on the underlying principles and concepts on which modern algorithms are being designed. Anything that would allow a person 20 years out-of-date to come up to speed in the developments that have happened in the last 20 years.

As a bonus I would also appreciate any links to papers/resources on how modern data center topologies are constructed and used (if any exist).

I realise there may not be a "one resource" but a series of papers; for those that follow this field, what would you recommend?
