Actually, it's considerate. Given the choice of having all of your users suddenly shut off, or a small portion of them, the latter is better. Suppose that the number is 1% of people that get shown this page. This means only 1% of the p

Based on her response (at 53:40), I feel like she misunderstood the question. The first response "The nice thing about standards is there's so many to choose from" is probably because even if she proposes a curve with a flaw

I feel that the other side: zero cost to protect a sidechain, is a much bigger benefit. Presumably, the sidechain has mining rewards as well, which devalue the amount of BTC you get when going back to the main chain.

It allows for arbitrary rules. For instance, you could make some currency that has the concept of grain and wood, and then you could make a transaction that converts one of each into roads. I'm not sure why that would be useful, but it

I would hope that any sidechains to bitcoin that use proof of work would have a shared mining model, so that miners could mine both simultaneously.

It would be convenient if there was a data structure that could store the set of unspent transactions as a sparse tree, and easily add/remove transactions without knowing the full tree. Perhaps as a merkle tree. There might be somethin

I think a better law would be requiring labeling saying that it is DRM protected and you can only use consumables from the manufacturer. It shouldn't cause any additional cost to the manufacturers. The only harm would be the lost sales

I don't feel that the claim is even correct, that the size of the output is proportional to the largest size. I mean, assume that the largest size is 1024 bytes. Then take two files that are gigabyte each into 1024 byte chunks. Make a

My understanding is that the way cryptography is done is by having hardware entropy source in the CPU fed into some sort of hashing algorithm. Having a CSPRNG with only n bits of initial entropy either exposes the problem of if an attacker

Why are things like Mersenne Twister or linear congruential generators platform dependent? To me, there are three classes of reasons you would need random numbers: 1. Simulation. Things like Monte Carlo. In this case, only the statistical q

But how do you know to use defusedxml instead of the regular one? I've never even heard of it.

Many uses for hashing algorithms don't care about collision resistance (HMAC/passwords). Signatures/Certificates are not one of those things.

Presumably the 140 characters is more like a git revision number than reversible compression.

In every single thread about traffic I've seen, someone posts this. This is just not true at all in congested roads, and means that there is less traffic throughput since one lane can't be used. On a 5-lane (per direction) 65mph f

Also, less time on road means less cost for society of being stuck in traffic. Although, most risk of accident numbers I've seen are based on miles driven. I wonder which is the most important thing for frequency -- time, or miles.

If your dynamic content is static content that is dynamically updated (with the mutable path), then it would seem like it would behave as if it was a dynamic page. For example, think of a REST API that was pointed at a bunch of static json

The challenge is getting AC current, not DC as with the mega-moto shield.

Also, it looks like there are grants available to even get you started with some capital so it doesn't come out of pocket. Even better.

I don't think necessarily that the AI needs to be malevolent. It's more that a malevolent AI is the only one that's going to blackmail you from the future. Ergo, the malevolent AI is the one that's going to exist in the

Thank you for doing the crypto challenge by the way. Was a lot of fun, and I'm looking forward to the next set :). Has anyone else finished it in c# yet?

As someone who stayed at home as a kid playing text-only MUD games and chatting on IRC, I think your minimum requirements for interactions in VR is way too high.

ElGamal requires an inverse element, which isn't possible with colors to my knowledge.

Isn't the whole point of blocking third party cookies so that you don't send cookies to tracking sites? For instance, if you're on example.com, and it loads a resource on ads.shadytracker.com, that it sends no information to

I see this as an extrapolation of an expert system, which is an AI. It seems the more you know about how they work, the less they seem like artificial intelligence and more like some simple optimization problem. I suppose this is what the C

I think the idea is that you're heating up water anyways [for laundry/dishwashers], you might as well get power out of it. It's kind of the same principle as if you're using an electric heater, you might as well run a bu

There's a big difference between a 20-50 pound quadcopter travelling at 10-20mph and a 1500 pound Cessna flying at 150mph. Regulations for airplanes are strict primarily because the consequences of failure is loss of human life. Second
