A whole class of speculative execution attacks against CPUs were published in 2018. They seemed pretty catastrophic at the time. But the fixes were as well. Speculative execution was a way to speed up CPUs, and removing those enhancements resulted in significant performance drops.
Now, people are rethinking the trade-off. Ubuntu has disabled some protections, resulting in 20% performance boost.
After discussion between Intel and Canonical’s security teams, we are in agreement that Spectre no longer needs to be mitigated for the GPU at the Compute Runtime level. At this point, Spectre has been mitigated in the kernel, and a clear warning from the Compute Runtime build serves as a notification for those running modified kernels without those patches. For these reasons, we feel that Spectre mitigations in Compute Runtime no longer offer enough security impact to justify the current performance tradeoff…

American democracy runs on trust, and that trust is cracking.
Nearly half of Americans, both Democrats and Republicans, question whether elections are conducted fairly. Some voters accept election results only when their side wins. The problem isn’t just political polarization—it’s a creeping erosion of trust in the machinery of democracy itself.
Commentators blame ideological tribalism, misinformation campaigns and partisan echo chambers for this crisis of trust. But these explanations miss a critical piece of the puzzle: a growing unease with the digital infrastructure that now underpins nearly every aspect of how Americans vote…

It was a recently unimaginable 7.3 Tbps:
The vast majority of the attack was delivered in the form of User Datagram Protocol packets. Legitimate UDP-based transmissions are used in especially time-sensitive communications, such as those for video playback, gaming applications, and DNS lookups. It speeds up communications by not formally establishing a connection before data is transferred. Unlike the more common Transmission Control Protocol, UDP doesn’t wait for a connection between two computers to be established through a handshake and doesn’t check whether data is properly received by the other party. Instead, it immediately sends data from one machine to another…
