Investment in mining hardware whose value is tied to a speculative asset without fundamental value beyond utility. None of the current implementations can scale, so even their utility is questionable. There is a way to make a scalable trust

It's a winner-takes-all market, so there are absolutely strong economic incentives to build the best robovacuum control software.

The network connection side panel also seems to never open when you want it to, only to open 2 minutes later when you are watching a fullscreen video.

The toy example referenced in section 6.4 is actually closer to Spectre. It's missing the crucial distinction that the speculatively loaded address should belong to a page inaccessible from the current ring level. To see why that toy e

AMD CPUs are completely unaffected by Meltdown, since AMD checks permissions before fetching memory into the cache.

Emphasis on "mitigate".

WRONG. You fell for the Intel PR strategy. AMD is completely unaffected by Meltdown, since AMD checks permissions before fetching memory into the cache.

Much more leeway for "unintended cheating" with 2D signals. Think of all the imperceptible patterns that could be used as distinguishers. ML methods basically search for these shortcuts.

Same can be said of CryCash: https://crycash.io/ CryTek was on the verge of bankruptcy a year ago when they were unable to pay their employees. The one-time payment from Amazon in exchange for the engine distribution rights

Yep, I was actually debating whether I'd mention sendmmsg/recvmmsg in my original post but I left it out. Definitely an option for UDP, but you're out of luck if your game server uses TCP (surprisingly many do) because you ha

No no no, you can easily train the branch predictor by sending a bunch of valid requests followed by an invalid request with a payload that redirects the ensuing speculative load into your desired address range.

Intel's L3 cache is inclusive. Spectre most definitely also applies across different cores.

Huh, so did Intel know about this vulnerability when they designed SGX?
