    https://en.wikipedia.org/wiki/Dynamic_random-access_memory#P... It turns out they intentionally drain a bit of the storage capacitor, and amplify that weak signal. Some of that amp…

    In my personal projects, I've used it to insert/delete transactions in a ledger. I wanted to be able to update/query the account balance fast. Like the article says, "fold operatio…

    Are we sure that the base reveals nothing about the factors if n is composite? I have never seen a proof of that. Usually, zero knowledge proofs also require a prover who knows the…

    This article is not about the API contract of the hash function, or the abstraction it provides. If you are just trying to hash things, you don't need any info here. It's very much…

    I still don't see the settings. Can anyone help?

    The hash functions used for these purposes are usually not cryptographic hashes. They are "perceptual hashes" that allows for approximate matches (e.g. if the image has been scaled…

    Kind of? Keep aside quantum mechanics for a second. In any classical experiment that has random outcomes, would you say that the probability distribution is a property of a single …

    This is like online reviews. If you selectively take positive or negative reviews and somehow censor the rest, the reviews are worthless. Yet, if you report on all the ones you fin…

    I have been donating a few hundred dollars to Mozilla every year (or at least most years) for the last 7 years. It's not much, but I might stop that donation now.

    I didn't get from the article: are they better than all traffic signals, or signals with unprotected left turns? And what's a good vs. bad turnabout like? I have had to go through …

    I'm interested in attending these in my area (SF South Bay). How should we discover similar meetups? Is there a place we should subscribe to?

    It might vary from state to state. Here in California it's pretty inconsistent. Anecdotally, in Virginia it was almost always there for every product.

    For one, it's really close to the upper end of how massive a neutron star can be. https://en.wikipedia.org/wiki/Tolman%E2%80%93Oppenheimer%E2%... says the limit is around 2.01 to 2…
