Auditing a Solana protocol isn't just about finding bugs.
It's about understanding the protocol's invariants, tracing attack paths, proving them with PoCs, fixing them, and testing the fix.
That's what my @rektoff_xyz C5 capstone put me through. 🧵

Breaking : China just achieved it the world’s first 1,000 km hollow-core fiber-optic breakthrough speeds up to 30% faster than traditional cables.
in latency terms than traditional cables over 1,000 kilometers.
64 Tbps bidirectional.
uploading/downloading 160 4K movies per second.
This is the quiet infrastructure leap that will power the next decade of AI and computing.

P.S. the last two are the exact math inside π0 and GR00T: a transformer that understands the scene, and a diffusion-style head that turns noise into arm motion. the article below shows how
🇺🇸 The US is pushing back against the data center boom.
33 proposals restricting data center construction have been approved, with another 6 reportedly leading in preliminary results.
The concerns? Massive electricity and water consumption, pressure on power grids, and rising utility bills.
In 2024, US data centers consumed 192 TWh of electricity, representing 4.7% of total US electricity consumption.
Not all proposals seek outright bans. Some target resource consumption and stricter permitting requirements.
The big question: Could public opposition slow down America's AI infrastructure race?

These guys used WiFi to see how may people where in a room. They used one @arduino board and two @Atech_dev boards

Thinking of starting a community for people who want to learn hardware, work in hardware, or just enjoy tinkering with things in general.
Reply to the tweet if you want in.

I have open sourced the ai harness that I made for security research, it produces the correct areas to look for the vulnerabilities and fails in spotting the correct bugs directly, still in early phase.
Thanks to @asen_sec for the guidance on custom tooling via his blogs

🚀 Google is taking AI infrastructure beyond Earth!
Under Project Suncatcher, Google is exploring the possibility of building AI data centers in space.
☀️ Why space?
Abundant solar energy.
Potentially new approaches to powering AI infrastructure.
A future of orbital AI computing.
But challenges remain: cooling in space, radiation protection, and satellite launch costs.
This is an interesting direction for the future of AI infrastructure.
Imagine data centers operating in Earth's orbit!
