I have to go back over and stitch in the edges on all my iron-on patches, might have to look into that if they'll do a better job.

In the tech industry, when a system doesn't work and can't be fixed we throw it out and start over.

I plan to, which pisses off Doctor Evil's Democrats.

Good, get it all offline so the LLM Assholes can't use it.

Lol, worst autocorrect ever. XD

Dunno! I haven't been to Twitter since Elon bought it and activated our scorched-earth protocols. Twitter hasn't been accessible on any device in our network since then.

Queer folks have a bad habit of falling in love with people on the other side of the country.

Crypto is just as insecure as credit cards. The whole point of the blockchain is that everyone can see all transactions.

I work in this industry and I can confirm that there's fucking nothing ensuring the privacy of these transactions. Tens of thousands of people have full access to everyone's credit card history, and that's not counting unauthorized access and card skimmers.

A "side-channel attack" is one where fundamental flaws in the encryption implementation method are targeted, as opposed to flaws in the cryptographic algorithm itself.

By means of analogy, if your cryptographic method is to go to a locked room to have a private conversation, then a spy doesn't have to pick the lock if they can still hear you through the door. The locked-room security method itself isn't flawed, but implementing it without a soundproof door has much the same result.

In this case:

The threat resides in the chips’ data memory-dependent prefetcher, a hardware optimization that predicts the memory addresses of data that running code is likely to access in the near future. By loading the contents into the CPU cache before it’s actually needed, the DMP, as the feature is abbreviated, reduces latency between the main memory and the CPU, a common bottleneck in modern computing. DMPs are a relatively new phenomenon found only in M-series chips and Intel's 13th-generation Raptor Lake microarchitecture, although older forms of prefetchers have been common for years.

Security experts have long known that classical prefetchers open a side channel that malicious processes can probe to obtain secret key material from cryptographic operations. This vulnerability is the result of the prefetchers making predictions based on previous access patterns, which can create changes in state that attackers can exploit to leak information.

So, the encryption the chips use is solid, but some of the hardware employed can still leak data.

I presume this is intended to be an insult, but you're gonna have to explain that one. XD

Voters don't even have opinions, they just pick between the genocidal geriatrics chosen by the real owners of this country and then shut up for four years.
