Wouldn't "row" be a better name for this?

> anti-european sentiment

The scientists are using evidence to assert something. Maybe it's flawed but unless you're going to publish and refute it, calling it "anti-european sentiment" based on nothing makes it seem a awful lot like you're the one being political.

Am I wrong in thinking that this is the first time we have seen hi-def video of the earth from this distance?

I'm not sure which is more funny: that his name is Cheddar Man, that he looks like Jerome Jackson, or how butthurt the racists are going to be.

Good for them. There was a good amount of production value in the broadcast. It seemed an odd creative choice to leave the audience audio feed maxed the entire time.

I could've done without the constant clapping and screaming on the webcast. Kinda took away from the experience for me.

I just watched Netflix's Dirty Money episode on HSBC. If you want to throw up in your mouth a little check it out and see how the Obama admin bent over backward to make sure they got a slap on the wrist for knowingly and purposefully laundering terror and drug cartel money for about a decade. Too big to jail is apparently very real.

I agree. I have a comment somewhere in my history saying the same thing. No matter how decentralized we like to imagine crypto to be, the fiat on and off ramps are highly centralized and can bring the whole thing crashing down in a hurry.

You didn't mention the $50K minimum, which obviously weeds out most people who would want to claim USDT->USD:

For the time being, we will only process requests above $50,000 in size. We believe that by the time we are able to get to the smaller withdrawals, other, less cumbersome

From your use of the word "leftists", I suspect you and I wouldn't agree on much; however, on this point I agree with you. Someone above mentioned the "paradox of tolerance" and I think your observation fits perfectly with that. I feel strongly about many of the same things that BLM and MeToo does (just to give some concrete examples) but I don't think believing in those things necessitates erasure of people who think differently. Unfortunately you find a lot of the "erasure" sentiment out there and usually they are the loudest voices.

The fact that this flaw is known and in production gives credence to some of the AI experts who are saying level 5 is waaaaay further away than we are being led to believe.

It was only a few years ago that almost all of this article applied to me. I remember before the cfpb forced banks to make overdraft "protection" out-in and being charged $35 instead of the card being declined. I remember biking across town at 5in the morning to make $35/day at a day labor place then giving 2 of those dollars to a check cashing place. Unless you've been poor, you really have no idea how hard it is to get out of that position. And if you have anything on your record, you can forget about not being poor. A record is a lifetime sentence of poverty in America unless you have connections or family wealth.

Bad government in practice. There's nothing in socialism that says a government has to build an economy with zero fail-safes. Venezuela is in this spot because their government was lazy and opted to import almost everything using oil money. Had they built any semblance of a self-sustaining national economy they wouldn't be in this spot. Sure they might've had to cut some social programs as the price of oil tanked but it wouldn't be the complete collapse we see now.

Having worked in a couple thrift stores I concur. Only give clothes in good condition. If it's faded, stained, or holey just throw it out because that's what Goodwill is going to do and instead of helping them, you're costing them money (in labor).

>Granted, you could obfuscate things by varying the buffer length and padding the data stream

Or maybe sending the blocks out of order to be reconstructed according to a shared ordering key?

>In other words, they can see what the drone sees, pulling out their recognizable pattern from the radio signal, even without breaking the drone's encrypted video.

The most interesting part of this is how encrypted traffic leaks enough info to be reliably analyzed. Really cool stuff.

get it snipped. trust me. there's nothing wrong with how you feel but don't have another one. you'll thank me later :)

Seems like it crossed the barrier from internal to external once a blog post was made about it and it was published to HN. Just saying.

In context, sure. To be fair, the article's title used the phrase in context. Once you name something, you invite that name to be used both in and out of context, which will lead to confusion. That was my general point, although I made it more concrete than I should've by saying "no one would know what the hell....."

Cool stuff, but can I be crotchety for a sec? I wish we could dispense with all of the cute names given to features, techniques, abstraction, etc that are not intuitive until someone tells you what it means.

No one would have any idea what the hell "tab warming" means without being told, which seems unnecessary for something that is a simple concept to understand. It increases the cognitive load in a field that already has a lot of it. Please just give your hack and techniques descriptive names; or better yet, think long and hard whether or not the thing even needs a name. "pre-render on hover" would suffice. It's one more word and I know exactly what it means instantly.

Yes and no. A true lottery predictably periodic - it happens in rounds. PoW puzzles are async and so the chain can fork. The second property of the crypto puzzle kicks in here - the statistically predictable number of hashes necessary to solve the puzzle which can then be used to calculate an average time necessary to create a valid block. With a forking chain, it's this time gap that secures the chain against rewrites. So yes, PoW is used to distribute block creation among the network but it differs from a true lottery system in that it is not synchronized into rounds.

You refer to the ICO as fraud but I'm curious; what evidence do you have of that? If it comes down to "our app really doesn't need a token" then that isn't fraud. If it's "we're going to sell this token knowing that we're going to phase it out and just use fiat after launch" then that's fraud. I understand that as the technical guy in the room you might be uncomfortable with shoe-horning a token where another tech is a better fit; however, that doesn't constitute fraud, just bad engineering.

Save the report man. They aren't interested in the technical reasons of why a non-blockchain solution is better. In fact, they're not interested in the tech at all - they are approaching it from a fund-raising perspective. If it's fraud and you know it - leave. If it's not, do the ICO, raise the cash and save your company.

In distributed ledgers, it doesn't matter who the leader is. The system only has to ensure that leadership is distributed in such a way that it is statistically infeasible or economically unprofitable to rewrite history.

PoW distributes the leadership (block creation) via crypto puzzles. PoS tries to use economic incentives to make bad behavior more expensive than good.

There's work being done (which I personally believe is the right way to go) in using a leader election-based system that works like a lottery (Algorand[0] is an example). The basis of such a system is going to be the creation of non-biasable pseudo-random number generation.

Along these lines one of the more intriguing projects is called RandHound[1]. It's a way of creating distributed randomness (according to the paper's title). I think chains secured via lottery leader selection protocol has more promise than PoS.

Edit: for clarity

A lottery-based system works because the "winning numbers" (imagine a winner being a node whose public key when XOR'd with the winning number is below a certain value) are known to all (a protocol like randhound ensures that all nodes know the winning number). A winner's bundle of transactions are validated as his/her's by cryptograpic signature (which can be verified using the same public key that is used to confirm this person is truly a winner). Those are the broad strokes. Obviously there's a lot more to getting it to work. I've been working on it for months and still haven't gotten around to putting it down on paper.

Given that there are so many new people showing up because of crypto, I think it's helpful to flag AND explain what is historically appropriate for HN. The rule says don't feed egregious comment. Considering I'm the only comment, I don't think that's what I'm doing.

Flagged. This has what to do with hacking, computer science or programming again? I'm into crypto but stuff like this doesn't belong here.

There are quite a few projects vying for owning the next generation of block chain. Generally known as ffm tech (fast,free,and minerless). They depend on some variation of PoS, hierarcal blockchains, and Byzantine consensus algos. Basically there's lots of serious work going into making blockchain ledgers scalable to permit money-like usage.

Some examples are Raiblocks and Ethereum's Plasma protocol.

While I understand that my smartphone can be used as a listening device, the day when I will purchase a dedicated wire tap for my house will be never. I've been to people's houses that have them and sure they're fun when you're having some beers and want to hear a song I don't mind taking 2 seconds to manual select a song on my phone to keep a hot mic out of my house.

One need only take a look at Kodak's sales in the last decade to see why this is happening. Just like we got Long Blockchain as a ploy to keep the company stock from being delisted,I'm sure we'll be seeing many more companies that are circling the drain looking to blockchain as a hail mary. This doesn't mean that there aren't legit use cases for the tech, but we're gonna be seeing a lot of shoe horning into blockchain in the coming years by failing companies.

In Tron's (TRX) case, the project's whitepaper is plagiarized [0] from Filecoin's, and the CEO (Justin Sun) dumped 6 billion tokens [1] after pumping the price by announcing "partnerships" that turned out to be him hiring developers. TRX is the literal definition of a shitcoin, yet the price pumped 10x in less than 10 days.
