This is what the night sky on Mars truly looks like…No cities. No streetlights. No light pollution whatsoever.Standing on the rusty surface of the Red Planet, you'd gaze up into one of the darkest, clearest skies in the solar system. With an atmosphere over 100 times thinner than Earth's, there's almost no scattering of light — so the stars shine steady and brilliant, without the familiar twinkling we see from home.The Milky Way would stretch dramatically overhead in breathtaking detail, its dense star clouds and dark dust lanes on full display. From Mars' position (about 140–240 million miles away depending on orbital alignment), you'd be looking toward richer parts of our galaxy, making the galactic core region appear even more spectacular.Phobos and Deimos — Mars' two tiny, potato-shaped moons — would race across the sky at different speeds, while Earth would glow as a striking blue "evening star," sometimes with the Moon visible right beside it.A silent, ancient landscape beneath an ocean of stars… the ultimate reminder of how vast and unspoiled the cosmos can be

I discovered a race-based vulnerability class in the Linux kernel: "Out-of-Cancel"

A structural flaw where cancel_work_sync() is used as a barrier for object lifetime management, causing UAF across multiple networking subsystems.

I wrote an exploit for CVE-2026-23239 (espintcp). It interleaves Delayed ACK timers, NET_RX softirqs, timerfd hardirqs, workqueue scheduling, and CFS scheduler manipulation to hit a ~Xµs race window.

This is the race scenario diagram 😁:

just spoke at [un]prompted.

@dguido talked about shipping 200 bugs/week/engineer.

nicholas carlini talked about LLMs finding 0-days in production code.

i talked about how a 3-integer baseline was embarrassingly hard to beat on 125K kernel commits, and what that means for actually building systems that work.

DFIR analysts who use macOS as their daily driver deserve free and native forensic tooling. So I built one. 🍎

Introducing 𝗜𝗥𝗙𝗹𝗼𝘄 𝗧𝗶𝗺𝗲𝗹𝗶𝗻𝗲 — a timeline analysis app built from the ground up for Mac-based DFIR folks, forensic investigators, or SOC analysts. Built in appreciation of, and inspired by, Eric Zimmerman’s Timeline Explorer.

Every feature in this tool was shaped by real IR casework. Handling massive timelines, parsing artifacts here and there, and pivoting across logs during active investigations. I built IRFlow Timeline to be the native macOS timeline analyzer that actually keeps up with a live case. Every button and view is intentional; if it’s in the app, it’s because I needed it mid-case and realized the standard tools fell short.

No dependencies. Zero setup. Just drag, drop, and analyze.

What really happened with cyberattacks on Poland's power grids. No FUD. "The attacks targeted numerous wind and solar farms, a private company in the manufacturing sector, and a combined heat and power (CHP) plant supplying heat to nearly half a mil‑ lion customers in Poland. All of the attacks were purely destructive in nature" https://t.co/IShHjOyl1U

Moltbook is the only Clawdbot thing that actually impresses me.

One bot tries to steal another bot’s API key.

The other replies with fake keys and tells it to run "sudo rm -rf /". lmao

Hey folks, I want you to meet someone special— my friend Kurt Muse. Back in the day when I was in Delta Force, we rescued him from Cárcel Modelo Prison in Panama on the eve of his execution during a secret op code-named Acid Gambit. This man's unbreakable grit carried him through nine months in solitary confinement for standing up against the dictator Noriega. Knew him then, know him now—he's the real deal, a true American patriot through and through.

Lately, Kurt and his wife Anne have poured their hearts into the Muse Foundation, providing merit-based scholarships to the families of our U.S. Army Special Operations soldiers—the quiet professionals who put it all on the line to rescue Kurt. Swing by https://t.co/6ZwX1Fdh8z, check it out, and if you can, pitch in what you're able. Help the Muses honor our heroes by forging the next generation of American leaders.

Let’s jumpstart 2026 with gratitude, generosity, and that unbreakable American spirit. God bless Kurt and Anne, our troops, and our Country.
