Reality update: Keylength – Compare all Methods … :
“This web site implements mathematical formulas and summarizes reports from well-known organizations allowing you to quickly evaluate the minimum security requirements for your system. You can also easily compare all these techniques and find the appropriate key length for your desired level of protection. The lengths provided here are designed to resist mathematic attacks; they do not take algorithmic attacks, hardware flaws, etc. into account.“
“To address the second challenge, we present ECCploit, a new Rowhammer attack based on composable, data-controlled bit flips and a novel side channel in the ECC memory controller. We show that, while ECC memory does reduce the attack surface for Rowhammer, ECCploit still allows an attacker to mount reliable Rowhammer attacks against vulnerable ECC memory on a variety of systems and configurations.”

“A 6,000-word report published in the New York Times last week disclosed in humiliating detailthe lengths to which Facebook has gone to protect its dominance and attack its critics. As various interlocking crises concerning hate speech, misinformation, and data privacy widened, top executives ignored, and then kept secret, evidence that the platform had become a vector for misinformation campaigns…
Over the past year, I’ve spent time trying to wean myself off tech mega-platforms, generally with little success. Google’s search, for all my complaints, is still the best way for me to navigate the internet; Amazon is still so unbelievably convenient that the thought of quitting it exhausts me. But I logged out of Facebook more than a year ago and have logged back in fewer than a dozen times since. Checking Facebook had been a daily habit, but it also hadn’t improved my life or made itself necessary. Not many Roman plebes would have said that about the Pax Romana. Some empires fall because they’re invaded from the outside or rot from within. Zuckerberg’s could be the first in history to collapse simply because its citizens logged out.“
“Let’s apply that reality to our robe example. Let’s say the robe costs $60, and yields a $20 profit for our e-commerce advertiser, not including marketing costs. That means that same advertiser is can spend upwards of $19.99 per unit on advertising (more, if a robe purchaser turns out to be a “big basket” e-commerce spender). So what does our advertiser do? Well, they set a retargeting campaign aimed anyone who ever visited our erstwhile robe’s page. With CPMs averaging around a buck, that robe’s going to follow nearly 20,000 folks around the internet, hoping that just one of them converts.“
