Tail Call Optimiztion in BEAM vs Rust loops for HFT systems:

BEAM/Elixir:
+ Guaranteed tail call optimization
+ Million+ concurrent processes trivially
- GC pauses
- Less predictable latency profile

Rust:
+ Explicit loop = zero-cost, predictable
+ No GC, deterministic performance
+ Sub-100μs consistently achievable
- Manual concurrency management

For market data aggregation? BEAM wins.
For order execution? Rust every time.

Papyrus: A Systems Engineering / MBSE tool for modeling in SysML, UML, etc. Basically a java-based FOSS replacement for Sparx Enterprise Architect. It's part of the Eclipse ecosystem.

I decided to give Papyrus a shot this year for a small work project and it has been pretty good. It's a large and sprawling tool that can be used a whole bunch of ways and I'm barely scratching the surface.

There aren't many tutorials available on youtube but my "just try things and figure it out" approach has been reasonably successful. Worth a look if you're in the market for such things: https://eclipse.dev/papyrus/ #SystemsEngineering #MBSE #SysML #UML

1. "Our problem has unique requirements"
2. Builds custom solution on "specialized" platforms
3. Realizes Postgres could have handled it fine

Everyone's use case is exceptional... until you prove it isn't.

Sometimes, I suspect #SystemsEngineering is about how to deal with *unnecessarily* complex projects due to socio-political factors.

A true Systems Engineer can get anything DONE no matter what !!
In time, budget and quality.

You need both Soft and Hard skills, but ...

BTW, not evident from the picture, but the linkedin post at the head of this thread complements @rollingstone.com for accurately describing the #systemsAI #systemsEngineering steps Grok (the corporate entity) took to address the harms. See slide incl. alt text for Musk's ignorance of how LLM work.

A slide about how large language models work. I'd been drawing this on whiteboards for my students, then made a slide at a consciousness meeting where philosophers were confused why LLM never say they aren't sentient. [I hope it's evident that this is informed conjecture, not verbatim truth.] Thus the 3 people in the history of the Internet who ever wrote "I'm not sentient" are out in the fringes of the data, as is the one person who ever said "Check it out, MechaHitler!" However, Musk's attempt to use a second set of guardrails to push Grok right also pushed it towards the under-informed data fringe with the MechaHitler comment. The bottom of the slide says "False statements are not lies, nor hallucinations; just adequate predictions from an inadequately informed part of the data space."

🚀 Project ELPM Update: PyQt6 Desktop App v1.0 is LIVE!

I’ve rebuilt my real-time process monitor from the ground up now with a sleek, native desktop UI using PyQt6.
It displays every running process, integrates deep system logic, and uses my custom elpm-killer.c for secure signal handling.

Here's how i did it:

To get the perfect design, I started by building a React + Vite web app — it gave me full control over animations, styling, and UX.
But I wanted a true desktop experience, so I didn’t stop there.

Next, I recreated the entire UI in Qt Designer, learning PyQt6 from scratch.
Shoutout to Python GUIs — their tutorial made the learning curve smooth and fun.

Converting the Figma-like design wasn’t easy.
No direct export, so I manually translated every component, layout, and style into .ui files — then converted them to Python.

The result? A native, cross-platform desktop app that mirrors the web version — minus web-only animations, but with full system access.

Still some polish needed, but the core is solid.

Behind the scenes:
✅ Real-time psutil monitoring
✅ C-based privileged actions (elpm-killer.c)
✅ Group-based permissions for security
✅ Button signals tied to process control (kill, suspend, etc.)

This is v1.0 — but not the end.
Next:
🔹 Malware detection (YARA + heuristics)
🔹 Hidden process & rootkit scanning
🔹 Desktop alerts for suspicious activity
🔹 Full export & analysis tools

Gonna work on the GitHub repo ready for anyone who wanna test it out 😁

In case you ask Why a desktop app?

No localhost, no config headaches. I tried that and trust me it isn't worth the stress at all 🤕

Just double-click and run — works on Linux, Windows, macOS. That's far better

This project started as a curiosity and deep learning about processes, then, grew into a tool I now use daily.
As someone passionate about low-level security and system internals, building ELPM (Enhanced Linux Process Monitoring) has been one of the most rewarding challenges in my journey.
I’m sharing it not just as code, but as a piece of my craft.

If you’re working in defense, red teaming, or just love systems I’d love to hear your thoughts. Let’s connect and build something powerful together.

I’m not sure how to describe the feeling I’m sitting with after having discovered a massive security vulnerability at my organization, in which remediation will be a huge god damned deal and assuredly a pain in my ass - as a result of someone else’s carelessness and/or ignorance.

I can only hope the Germans have a satisfying multisyllabic word for it though.
