Many people are asking why it's a problem, why don't advertisers just pay less, etc. The adbots are making money off of this, otherwise they wouldn't do it, and that money has to come from somewhere . Meanwhile, they don&#x2

Do you have experience interviewing candidates? Many candidates will answer this question correctly and yet be totally unable to do anything when they're confronted with a non textbook case. To be clear the brain teasers I ask are math

Can't be too specific, but I often need to solve differential equations, find closed form solutions to some integrals (mathematica helps but is often not sufficient), build models which strike a good balance between realism and tractab

I work as a quant and I like to give brainteasers in interview. It definitely does not tell me if someone will necessarily be good at his job or a good fit for the team, but it does help me rule out a lot of potential candidates. These are

Probably not, it would have likely been netted between the banks without requirement a settlement.

Centralized vs decentralized is not a box to check, there are major costs associated with it. Imagine for instance someone suggesting that a supermarket offers coupons on a distributed ledger. Sounds like a good idea? No, it's dumb. It

There are, but I contend that most of what is being hyped makes no sense. What are the applications that can truly benefit from this model according to you?
820.
by murbard2 12y ago
That depends on your threat model, that depends on what you're trying to achieve. There are very large engineering costs to using this type of solution, and in many cases, the benefits are much lesser.

There is tremendous value in distributed ledger, but also tremendous empty hype at the moment. As a rule of thumb, people who tout distributed ledger based solutions ought to ask themselves the following questions: - Can this be replaced by

I don't see how using TLS would prevent MITM in this case. TLS only prevents MITM if you know public key or if it's been signed by a CA, but neither is the case here.

How cam bitmessage possibly be worse than Tor? All that bitmessage indicates is that you're taking part in the network, not what you're actually saying or who you're talking to.

You have to differentiate the actual network that holds the data (possibly as a DHT) and the network implicitely described by the statements. The way you avoid clique is by staying within your clique. That is requiring that the entities you

Reputation systems do not need centralization to have enough data points, what they need is traction. That can very well be achieved with a decentralized system. But most importantly, the idea of making "trust" graphs using a weak

Please, do not run this on Tor. The p2p aspect will definitely help, as it will be harder to locate a single server with traffic analysis, but it isn't enough. Run this on bitmessage (or a fork thereof) which broadcast messages to all

What are your thoughts on using LSTM? The google paper is using it, but it seems you're not.

Allegedly. Just because the DA says so doesn't mean it's true.

It's not super grammatical. I think the right way to do this is to invert a text compressor. 1) Take a state of the art text compressor like cmix ( http://mattmahoney.net/dc/text.html#1243 ) 2) Compress a very large

Yes, it's called a prior, and there's nothing wrong with that.

Maybe not. Not all probabilistic programming relies on MCMC, you can do MAP with probabilistic programming too. But in general, it's true that it tends towards Bayesian integration. In a sense, MCMC tries to solve #P complete problems,

Why do they look for collapse. There's no evidence whatsoever that wave functions collapse.

Ah got it, you simulate individually per atom, I thought you were describing the entire population. Indeed, you can always use that vector as the parameter to a multinomial distribution and recover the real distribution. Regarding the Paret
