Just to play devils' advocate:

I totally believe that we could identify any normal alloy, but what about more far-out kinds of materials? Humans have already experimented with metamaterials, weird composites made of many different kinds of constituents layered or interposed in various ways, materials with embedded electronic or even "smart" computational capabilities, etc.

Now imagine what a more advanced civilization might be capable of producing. I'm imagining a composite with embedded "smart" programmable behaviors that is 3d printed at the atomic scale. Every single atom is positioned intentionally to yield "smart matter" with incredible strength or other really exotic capabilities.

I can imagine it being difficult to identify or characterize such a thing without destructive testing, and if we did have such a sample we'd probably be very reluctant to do that.
yeah, darknetmarkets should have dropped bitcoin completely a while ago

I'm not sure Monero's 2-of-3 multisig is actually merged into production yet, but they have 2-of-2 so thats still a real limitation. Also Monero has and will hit performance bottlenecks very quickly too, cryptonote coins have no layer-2 scaling solution on the roadmap. Although they have had adaptive block sizes from day 1, the block sizes grow very slowly compared to spikes in traffic. The transaction fees would quickly reach unoptimal $ amounts, but the market itself would just require larger deal flow.
I agree that electronic deception is a real risk, though I tried to cover this briefly with "on a well-known domain name." To be more specific, if the site isn't a name-brand PWM, brokerage, or custodian bank domain (examples: ubs.com, vanguard.com, fidelity.com), find out why. I agree that a site is easy to put up, but getting it on a domain name visited by hundreds of thousands or millions of people is not.

(And yes, a few tiny PWM firms do use their own Web sites, and you should be much more skeptical of the data you're getting from a 6-employee firm's site). Get access to your custodial account at a name-brand firm's site, or change asset managers.)
Sourcegraph is also working on a similar service.

Also: unless you've okayed the name with the Git folks, you're going to need to change the name. Git is trademarked, and they are no longer allowing just anyone to use the mark without first seeking permission. (GitHub, GitLab, and others have been grandfathered in.)

Lots of love for the rich kid on this site.
Delivering ad-free content is potentially a billion-dollar business. I'd be happy to pay a flat fee and read articles online, watch TV, movies, documentaries et cetera ad-free. Off course, some content services offer this. The problem is twofold: "new" services I discover still give me ads, and I need to subscribe to many services to get ad-free content.

I much rather have one service I pay to resulting in many content providers allowing me to consume ad-free content.

Or just continue on being useful to a small fraction of people. It doesn't have to be this massive market.
Bitcoin undoubtedly is a technical and social phenomenon, but it’s also definitely almost useless as a digital currency at the moment. Other alternatives like Bitcoin cash, litecoin, ethereum etc. are much more useful for actually... sending money to people. The dev team needs to make Bitcoin as good as Venmo for sending payments between people, or someone else will beat them to it. People have talked for a long time about currency X being better and replacing Bitcoin but with Bitcoin rising so fast that the network has basically shut down, this may be the first time another currency or fork has the opportunity to overtake it in market cap.
It happens all the time, and there is no recourse unless you can get lucky enough to cause a social media storm with enough outrage it catches someone's attention.
You've described how BTC can scale as a currency, but haven't addressed ardit33's first point, which is that not many people seem to want to use it as a currency in the first place.
The vast majority of packages don't need extreme security.

Personally I don't care about security of my packages at all—they just sit outside my door for me. If one is lost/stolen, Amazon will happily replace it.
How is that different than the folks from pets.com starting a new company, like wag.com?
Bcash is at high risk of a 51% attack unless they change their proof-of-work algorithm

Litecoin is equally cheap, has fast block times and no such risk.

Neither will scale sufficiently without off-chain transactions.
I don't want to overstate it; I've written a lot of SIMD in my life too. If you've got audio processing that needs to run in a realtime thread, I can see how SIMD is appealing, because we don't really have mechanisms to achieve realtime on GPU (yet). However, for a lot of seriously heavy computation, it seems like doing it on the GPU is a win. For the cases where memory transfer back and forth to the GPU is expensive, even integrated GPU should offer significantly more computational resources than even AVX-512.

One of the use cases I'm thinking of is font rendering, where I published a SIMD-heavy prototype a couple years ago, and it's blown out of the water by a newer GPU-based approach: http://pcwalton.github.io/blog/2017/02/14/pathfinder/
This idea that we have a database that covers all possibilities for anything that would qualify as alien is delusional. It's like Neatherandals claiming that they have a complete database for hard things, and it contains exactly two entries: rock and stick. If they somehow stumbled across an iPhone, and ran a few tests, they would decide it is a rock (since it can skip across water - just like other flat rocks). In the very near future we will have complex dynamic alloys that do not fit neatly into any database because their characteristics will be change depending on the surrounding conditions. This is by a species that can't even build a space elevator. Who knows what is possible for a species capable of interstellar travel.
I’ve had the same isolation experience after kicking Facebook 3ish years ago. Also, it seems to have only gotten more isolating since. My wife effectively has to operate as a proxy between most of our family/friends and me, which is not a position she enjoys, and is not a position I intended on her being in.
While I don't doubt that Harry Reid is as corrupt a politician and as expert at funneling money to his cronies as, say, the late Robert Byrd was; there are A LOT easier and quieter ways of making it happen.

Especially for a sum as small as $22 million. Even county-level politicians can make that amount of money disappear without a trace and without leaving behind a warehouse and a paper trail.

To play the other side: What we have in the linked article is a couple of people who have never seen the objects in question stating categorically that they don't exist, or are ordinary. I'd believe the skeptics more if they'd at least seen the objects. But it's just a couple of guys several thousand miles away second-guessing some other guys with actual access to the objects.

Thanks, for the clickbait, SI. Next...
This has nothing to do with the parent.

They should probably focus on implementing segwit instead of these shenanigans.

BitPay lost a lot of credibility when they published instructions telling people to "upgrade" their Bitcoin wallets by switching to btc1, which was a hardfork that failed spectacularly. What they did was bordering on fraudulent.
Still, at ~26 transactions/sec it's a far cry from something like Visa.

Maybe we can do much better international trade with it tho.
Yeah, if you are willing to buy that they have something stored they can't identify, this is the most logical explanation.

That said, I would still buy that there are probably almost no materials that we couldn't at least get a handle on. If they were truly incomprehensible it would likely be because they were the result of manipulating properties that we don't even know exist yet (higher dimensionality, etc, whatever other sci-fi shit), and I feel like something that sensational and world changing would be incredibly hard to cover up.
Reaction time and APM (in RTS) pretty much dominates every other skill in terms of game outcome for most of the competitive games out there. Maybe if turn-based games develop a competitive scene.

Face it: you're over the hill, and so are most of the rest of us.
One reason and one only- to make it easier to sell user information. OKC has detailed, directly-stayed information on all its users’ likes and dislikes, of a sort second second only to that generated by Facebook (maybe.). If they (or some marketing analytics firm working with them) can figure out a way to connect your user profile made on your laptop to you as an Amazon shopper on your cellphone, that’s worth Big Bucks. Having a real first name makes this easier- and also makes the reliability of the process sound more convincing to executives who still don’t, deep in their bones, trust statistical techniques.
+1 for the (giant) list of idiotic quantum metaphors...
> This is why Bitcoin Cash (BCH) is gaining momentum with merchants.

source?
the value of gold is in no strong way tied to its industrial uses, the concept of "intrinsic value" being what drives market value is silly. If gold had zero industrial usage it would still be almost as valuable as it is now.

After all how much of money's value is due to the fact that it has a decent BTU value per weight in a furnace?

Most money is as purely a "digital fiction" as bitcoin is these days.
Are you part of the Roger Ver sockpuppet team? I see from your comment history that you might be.
Shopify is the one big standout.
> based on their current understanding rather than testing the claim.

The point is that there is no claim. It is very very straight forward to identify an unknown material (figuring out how it was made, what it's for, etc., is the difficult task). If you want to claim there's an 'unknown' material, show us your XRD patterns, your EELS/XPS/NMR/EDX/PL/SIMS spectra, your AFM surfaces, your electron micrographs, atom probe tomography, any number of a hundred other characterization techniques ... then you'd actually have a claim we could have an intelligent conversation about.

At this point, there isn't even a claim that needs an expert opinion to respond to, it's all just BS.
> a building in Vegas with some kinds of materials that have strange properties and we don't know where they're from or who made them or how

A lot stranger things have been found hidden in Vegas buildings than alien artifacts. Just a few weeks ago it started raining cheerleader uniforms in downtown Las Vegas because a demolition crew pulling down a hotel hit a sealed-off room filled with thousands of them.
When they lose 75% of the money they invested in Bitcoin, they can keep doing the same math and be happy about their "25% gain".

That plus the weather is why I'm a Canadian in California.
yes. Would have cost Full Contact way more to do it themselves from scratch (collect all the company data, get the customer list, the source code, and recruit 6 trained engineers who are ramped up on the source code)
Okay, but that just shows a natural decline from best to okay, vs okay to bad.
That depends on what is meant by "simulation" and the nature of the "proof."

The default assumption seem to be that it means our reality is essentially code running on some strange alien computer, something easily comprehensible which behaves like the Matrix, but that seems far too anthropocentric to be likely.

It would imply that our universe was designed, though, and that it appears to exist with intent, and would be incredibly annoyed that the theists appear to be half right, but still satisfied that they were half wrong.
Could you elaborate on which merchants use BCH? Would love to see any data you've come across or even anecdotes
If it's a paid account then they would already have that information. Is the quality of data they will mine from the free accounts worth it? I don't know. If you have the app installed they can already see your location and what not. Just seems like a bad move.
All I do is favorite the one's that I want to remember and then look back through them.
Surely premature optimization.
There are no fees on GDAX unless you're a taker.
Worth calling this out:

> We are also working quickly to add support for a Bitcoin Cash (BCH) payment option on all BitPay invoices. Bitcoin Cash is a modified fork of Bitcoin which will allow purchasers to send payments with significantly lower bitcoin miner fees. Bitcoin Cash payments will allow us to re-enable payments as small as $1 or smaller.
Just ensure you pick a "good" encoding scheme, because base64-ing PDFs will balloon that storage space in a very big hurry

Evidence-Based Health Policy
Are you part of the Blockstream/Core sockpuppet team? I see from your comment history that you definitely are.
What about storing each stream as a separate logical file in the tar file? So you have the main file, with a property of "nt_stream_count=2", and the file name for each stream would be the main filename followed by ":stream_id". That way each stream would show up as a separate file upon restore (assuming a standard tar is used for restoring), but the custom tar would know what to do.

Also, unrecognized pax data would be ignored by a regular tar.

And in my use case, when data is submitted by the client to the Snebu backend, it has its own tar implementation built in for separating file data from metadata, and re-synthesizes a tar file upon restore. (The reason that Snebu uses tar format for transfering, is it was a good way to make it agentless for normal Unix/Linux servers, yet extensible enough to support other use cases. Also I figured that most tar implementations were fairly well optimized, at least more so then I could do in a short amount of time).

Thanks for your input, really appreciate it. Been a little bit tough learning the WIN APIs, after a couple decades lost in Unix land.
https://news.ycombinator.com/item?id=15991784 has more, but basically, get access to Web-based results from name-brand bank or custodian. A legitimate PWM professional will already be using a custodian bank (or will be employed at a large bank like UBS, JPM, or BoA, so you'll have access to their employer's site).

Also, they'll appreciate that you're doing this due diligence. If you get any pushback, move on.

Also worth noting that this problem is mostly moot for a typical retail investor who has assets at a name-brand brokerage like ETrade, Schwab, or TD Ameritrade, and already has self-service access to the bank/brokerage's site. At that point, an individual advisor might be able to make unilateral allocation changes, but the money's there and the bank will have a trading history. This problem in this article basically starts with trusting a lot of money to an individual or tiny firm, and that basically only comes up in PWM and non-traditional asset classes.
I think the current "rots your brain" videogame thing today is more along the lines of watching let's plays of minecraft; in fact I have a couple younger cousins who don't even play minecraft, they just watch the let's plays.

I have feeling the bottom of the barrel has gotten a lot worse than it used to be.

Why Tesla cars have AC Induction motors instead of DC
https://www.tesla.com/blog/induction-versus-dc-brushless-motors

The above link was found in the original discussion board, which is here: https://forums.tesla.com/forum/forums/ac-induction-motor-why

Some key observations:

Batteries can't store AC electricity. One requires power electronics circuitry to convert DC to AC which might involve a trade off. Yet why go for AC motors?

Below are the arguments

- DC motors require rare earth magnets which can add to the weight of the motor which can be expensive & can't be mass produced. They can only be extracted. AC motors require the induction coil which can be easily manufactured. There can be numerous counter arguments to it, but when measured, advantages of AC motors manufacturing will always weigh more than DC.

- AC generators have 3% more efficiency than DC (as mentioned in one comment) during re-generative braking

- High Traction: Max torque at 0 rpm - this is something that only electric vehicles with high traction electric motors can claim. 3 phase AC induction motors have been known to give 100% of their torque as soon as you start them.
Agreed. I see this story several times a year. Usually with small time people with no contacts to get them help, but I have seen large companies lose control of everything as well. I just don't understand handing over mission-critical services to companies that offer you zero control or support in exchange for free or nearly free.
I speculate that at first people want to use it as a store of value, but after a critical amount of holders, and having a lighting network, users and merchants could also adopt it as a currency.

A conservative scenario is that cryptocurrencies will not really become adopted other than store of value: I think even in this case BTC value can go up tremendously. It has benefits over gold: like easy and fast transport accross countries.
A particular stream of payments with a particular risk profile is an asset that has different (present) value to different entities like any other.
It does. There's little point it debating which currency or index of currencies to analyze, when none of them are showing significant traction as a currency.
>Bitcoin undoubtedly is a technical and social phenomenon, but it’s also definitely almost useless as a digital currency at the moment.

Those who have truly drunk the koolaid call this a feature not a bug.
I think all block chain solutions have the same problem with scaling right ? IOTA sounds like it could potentially solve this since they seem to be P2P with accelerator nodes instead of relying on miners - but honestly I haven't looked too much in to it just put few hundred bucks to it if it actually ends up working.
None of the coins can scale realistically on-chain as a peer-to-peer system. If you run the numbers, the transaction volume of 1B people making one transaction a day goes into the terabytes. If you externalize the costs of verifying that to third parties, you lose properties that make Bitcoin interesting to begin with.

For many people it was clear that off-chain transactions are the only feasible way to solve this. Small purchases in particular do not need to be broadcast to the whole network and can be routed in payment channels. Lighting Network is the most promising solution at the moment.
I loved the books but Dark Forest theory makes little sense to me because it more-or-less assumes aliens have no concept of morality (the Trisolarans in the book literally have no morality).

If we became super-advanced, it's hard to imagine given our past (including sci-fi like the series) that we'd just go head and decide to wipe out anyone we encounter, even if we did consider them lowly. Largely for the same reasons there exist animal rights groups, etc.
Proper drug education would likely go a very long way towards ameliorating addiction problems (the main contributor to negative externalities in drug markets).

Why are people using heroin? Are they depressed? In pain?
What about amphetamines? Do they have ADHD?

Moreover, how many first time users actually know how to/understand the importance of properly titrating up, or even safe dosages of the substance they're using?

Not to mention that people taking substances for underlying mental issues might finally appear on the radar of their GP.
Then the currency will be debit/credit with your bank which has Assets on Sol-3 and the consistent activity there guarantees a steady value on the value of USD, GBP, EUR, etc.

If things do come to pass and a significant carbon mass is shifted off Sol-3 (human population), then currencies will fluctuate since that is what drives steady value. This value will fluctuate as bitcoin is now doing "if" the abundance of rare-earths is transmitted back to the Origin planet.

I'll say it again: "if".
If you're talking about ordering online they won't give you the most fresh items. They'll give you the ones which are still sell-able as fresh ie. almost moldy. Once those are gone, they'll give you the next one in line, but not the most fresh as you might pick yourself if you were in a physical store. Because those will still be sell-able tomorrow or the day after, but these which are almost bad aren't.

What this means is that when you buy an item which almost nobody buys fresh, like say apricots or coconuts (the case here, YMMV) and its easily perishable then you may end up with food which you gotta consume very soon once you receive it. If you buy an item in high demand with a high turnover rating you're probably good to go though.

Fresh is overrated anyway. Get a large freezer. I got all my bread in freezer, all bought on sale (50% discount). We generally toast it, but having it out of the freezer overnight also works. Same with frozen fruit (berries esp) and some frozen veggies. It doesn't deteriorate either, and stays quite tasty (better than canned, generally). And its cheap!
At this point, it's faster and cheaper to get the private key delivered by FEDEX than making transactions on the Bitcoin network.
Soon is relative. Most people have their bitcoin charts set on 1h.

I got introduced to side channel attacks 2 years ago, but only recently had the time to read up on RowHammer attacks. In particular, I was quite taken by the research on Clementine Maurice. Won't paste any links here but a quick Google search on her would lead to a treasure trove of her works.

There's much discussion about To The Stars between the Blink-182 frontman and John Podesta in the emails leaked by Wikileaks.
