It's too stable.

Today I worked through a CUDA performance checklist from gpumodel, studied memory coalescing via a blog by siboehm, and explored karpathy repository to understand and implement Muon. I’m also working toward extending this into a distributed version of Muon

RSA private keys biased toward 0 bits can be factored by swapping a hard math problem for an easy one: integer factorization becomes polynomial factorization.

We found hundreds of real-world keys vulnerable to this. Many traced to a type mismatch in CompleteFTP (now patched): each 32-bit limb got only 8 bits of randomness. We recovered 603 RSA and 74 DSA private keys. https://t.co/C2jcxVW9WG

FluentFlyout replaces Windows 11's media and lock keys flyouts with a modern, Fluent 2 Design-based interface that matches the system's theme and animations.

- Audio flyout with cover art, title, artist, and media controls
- "Up Next" flyout that shows the next track when a song ends
- Lock keys flyout for Caps, Num, and Scroll lock status
- Taskbar widget displaying media info directly on the taskbar

[ReactOS @reactos]

And this is #ReactOS ARM64 running on Raspberry Pi 5!

Back in 2022-23, our ARM64 port was only able to produce user-mode executables. While being in a experimental state, we could finally see ARM64 in action!!

@FordsterCAD and THEN if your tv model ever gets pwned and has its private DRM keys leaked, Google will blacklist your TV and you'll never be able to play in anything but compressed as fuck 480p again

the masses are discovering Widevine DRM

A Chrome extension with 7,000 users and a Google Featured badge was recently sold, weaponized, and pushed a malicious update to that executed code through a hidden pixel. Here's how it worked 👇

Interesting news that reveals why that out-of-band update for the vulnerability affecting multiple Microsoft Office products was issued. CVE-2026-21509, is being actively exploited in the wild and has already been added to CISA's Known Exploited Vulnerabilities (KEV) Catalog too.

🎯Malware name: DynoWiper
🔹Comment: On 29 December 2025, during the morning and afternoon hours, coordinated attacks occurred in Poland’s cyberspace. 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 million customers in Poland. All of the attacks were purely destructive in nature - by analogy to the physical world, they can be compared to deliberate acts of arson.

- absolutely from scratch
- not even libc
- the only dependency is The Kernel
