The security of RSA however depends on the factoring of very large numbers, and that means that for example, RSA-2048 doesn't translate into 2048 bits of security but 112 (roughly symmetric equivalent) bits based on the best factoring algorithms (for comparison, the RSA-512 the article mentions has an 56 bit equivalent and RSA-1024 has a 80 bit equivalent security, so RSA-1024 would take roughly 2^(80-56) ~= 17 million times to compute the worst-case scenario and RSA-2048 would take 2^(112-80) = 4.3 thousand million times more).

According to the Wikipedia article on RSA numbers, RSA-220 (66b) was factored in 2016, RSA-230 (69b) in 2018, RSA-240 (72b) in 2019 and RSA-260 (76b) this year, which is too close to RSA-1024 (80b) to be comfortable.

For RSA-250, the team reported it took "roughly 2,700 core-years, using Intel Xeon Gold 6130 CPUs at 2.1 GHz.". I am not going to (or feel qualified to) make estimates of how that would translate to RSA-1024, but it does sound plausible given enough resources.

The exception to this is obviously embedded systems with very low amounts of resources where C and assembly are practically unrivaled.

I'm not surprised they do this since advertising represents almost 3/4 of Google 's revenue. If anything, why should anyone expect something else? Company in the ads business modifies monopolistic browser to make money with ads and more news at 11. If it's not this, it's going to be another thing in the future.

In comparison, I've found small net places such as Mastodon or smolnets much more enjoyable even though the population is much smaller (which is nice since they also don't generate more information than I have time for). As a rule of thumb: The less interesting a place is for companies, the more pleasant it probably is.

Also reminds me of that black mirror from last season where the IT crowd guy damages his own body to entertain strangers so they give him the money he needs to support his wife. What's stopping someone poor without much to lose from burning down a forest if there's a significant monetary incentive?

I also had issues with node density. The way I solved them was by adjusting the forces between the nodes, particularly the repulsion and collision forces so that there is is no superposition. Values too high or too low can make the simulation chaotic or too dense, while others make it more fluid or faster to stabilize from an initial seed.

That being said, if it was a bigger simulation I probably would have had issues keeping the performance, and it's possible I would have considered a different engine.

I hope the japanese people are aware of this and trying to fight it back, because sure as hell doesn't sound like a legal change like this is worth it.

I imagine the flow would be something like (correct me if I'm wrong) [client request] -> [backend returns an error]/[accepts the request and waits for payment] -> [client sends the money] -> [backend accepts the transaction] -> [backend returns the requested data]. All of this sounds like a huge bloat over the current API key/token system.

What politicians should be promoting are campaigns and tools that help educate children and their parents.
