Serious vibes in the series finale of . I’m not an educated classicist and I know they had to change things for the show and its collapsing budget by this point, but I’m a bit skeptical that the real story was like this.

No wonder people see this show as a precursor to Game of Thrones - I may get round to watching that. I’ll have to rewatch season 1 later.

I also just bought Ten Caesars and will read it soon.

Intel accused of hiding the 'Downfall' CPU bug, faces class action

Intel knew about Downfall but chose to ignore it, plaintiffs allege

Anyone remember a game called DownFall? It was sold under the name of Milton Bradley, inventor of The Game of Life. Although by the mid-1980s was just a brand name of Hasbro.

Anyway, it involved dropping plastic tokens through a series of plastic cogs, which players took turns to operate. Hoping each time that their moves would allow their tokens to drop, but not the opponent's:

@anneapplebaum Wow. The extract from the book about Romney in the Senate is intense. It does seem that the US is failing, fast and badly, and that the failure is being brought about by a strong and active minority of politicians and voters. It seems to be happening at every level, from school boards to the Senate, and it seems to be happening fast and irreversibly.

Good article, but devastating.

So, between Meltdown, Spectre, Zenbleed, Downfall:

How many more speculative execution bugs are still left to be found?

Of the "performance gains" professed by speculative execution, how many are far less than the mitigations reduce performance?

Where my mind has been going recently, again.

Someone else do the benchmarking, please.

No one with affiliations with Linus Media Group, kthx.

"[Q] What is the overhead for the mitigation?

[A] This depends on whether Gather is in the critical execution path of a program. According to Intel, some workloads may experience up to 50% overhead.

[Q] Can I disable the mitigation if my workload does not use Gather?

[A] This is a bad idea. Even if your workload does not use vector instructions, modern CPUs rely on vector registers to optimize common operations, such as copying memory and switching register content, which leaks data to untrusted code exploiting Gather.

[Q] How long was this vulberability under embargo?

[A] Almost one year. I reported this vulnerability to Intel August 24, 2022."

I just finished watching , which I had previously seen a few times, and I was struck by the parallels between the ideological fervor of the in their final days, and the movement we're witnessing today. If you watch the film with that in mind, it feels almost like a of things to come.

Don't worry, AMD!

You aren't the only one leaking secrets!

“Downfall” bug affects years of Intel CPUs, can leak encryption keys and more https://arstechnica.com/information-technology/2023/08/data-leaking-downfall-bug-affects-six-generations-of-intel-pc-and-server-cpus/

“Downfall” bug affects years of Intel CPUs, can leak encryption keys & more

, aka CVE-2022-40982, is similar to prior speculative execution attacks.

All CPUs based on the Skylake, Kaby Lake, Whiskey Lake, Ice Lake, Comet Lake, Coffee Lake, Rocket Lake, and Tiger Lake architectures (6th-11th gen Core) are affected, along with a few others.

For systems that use Intel's SGX feature, a firmware fix is needed; otherwise, the fix can be loaded by the OS.

The saddest part of is that some underrepresented designer on the fediverse or something could have been given a few bucks for drawing a falling CPU, but instead DALL-E 2 got the job.

A new vulnerability was published for Intel CPU (Discovered 1 year ago but kept under secrecy until then). Apparently, downfall attacks allows to leak data across users, VM, etc running on the same CPU core.
A well-written page describing the issue can be found at https://downfall.page/
Also a paper written by the security researcher @flowyroll is available https://downfall.page/media/downfall.pdf

The mainline also[1] gained mitigations for the Gather Data Sampling (GDS) AVX2/AVX-512 hardware vulnerability which allows unprivileged speculative access to data which was previously stored in vector registers:
