Yeah I don't think this is a big-ish problem currently. But by having this vulnerability to point to, other CPU vendors have a good reason not to include this feature in their own chips.

There are definitely bullshit cves out there but I don't think that's a good general rule. Especially in this context where it's literally unpatchable at the root of the problem.

So the attack is (very basically, if I understand correctly)

Setup:

• I control at least one process on the machine I am targeting another process on
• I can send data to the target process and the process will decrypt that

Attack:

• I send data that in some intermediate state of decryption will look like a pointer
• This "pointer" contains some information about the secret key I am trying to steal
• The prefetcher does it's thing loading the data "pointed to" in the cache
• I can observe via a cache side channel what the prefetcher did, giving me this "pointer" containing information about the secret key
• Repeat until I have gathered enough information about the secret key

Is this somewhat correct? Those speculative execution vulnerabilities always make my brain hurt a little

Unrelated and I don't know if the mod will see this but thanks for your doing the work you do!

I knew who bugsy is before seeing the picture. I feel like I either should delve deeper into the fediverse or take a break. On the plus side of the fediverse is definitely bugsy. Hello bugsy.

Most pixeled Shit I've ever seen

That's pretty nitty although you can always just partition a long key and distribute the partitions to the different people

Let me jump in here then.

Those two questions are only somewhat related. The question "should we ban an undemocratic party that wants to work against core values of our constitution" has only become really pressing because the current government is so unpopular. The actual reasoning for or against the ban do not relate to the popularity of the government.

Taking the current state of affairs and concluding that voting enemies of the constitution into the government would be the solution is not something the majority has to accept as a valid political point of view.

You may call that antidemocratic but there are good reasons we have these non-negotiable core values in our constitution.

If you want to protest against the current government go ahead and I'll probably support you, there are many good reasons to do that. As long as you are not supporting the movement against our country itself.

Are you actually referencing the "first they came for the Jews but I wasn't a Jew" thing to argue that we should let nazis go ahead and take the power?

You even dropped a few accidentally and nothing happened! Complete duds these things really

Didn't the hole above Australia close again?

Having not read this comment nor caring to do so: Sometimes people post the first thought that comes to their mind even if it only barely relates to the topic.

Let's quote the oxford dictionary then:

opinion (noun) your feelings or thoughts about somebody/something, rather than a fact

In this context the opinion is the thought that the holocaust was only about exterminating jews. This thought does not align with the facts.

They are not factually wrong becuase their opinion does not match the popular opinion. They are factually wrong because their opinion does not align with the fact that the holocaust was not only about exterminating jews.

How can an opinion be “factually wrong?”

If I formed the opinion that the third Reich did not want to exterminate disabled people as part of the holocaust that would be factually wrong. That's how facts and opinions work.

Yeah I hate it when "the tribe" calls out my factually wrong opinions.

Trans, gay, Romani, Black people all got deported to concentration camps as well as jews. The death machinery worked against a lot of people, even if it was designed to exterminate jews.

They even had a badgesystem to visually identify for what "crime" someone was in the camp.

Edit: As well as other groups of people, a complete lists is basically impossible. Communists where early victims, but disabled people where also brought to the camps and killed for the "Volksgesundheit".

Don't forget to delete this comment before you call back to the original one. Otherwise the future people will know you aren't actually smart!

Edit: Also, hello there future people!

It means there was a majority of people who decided these people shouldn't be in charge after witnessing what they did when they were in charge?

And more importantly, is it ok if we carpetbomb his neighbourhood?

Fairly certain that wasn't me
