Therefore Visa is decentralized?

Bitcoin as a high throughput transaction network for buying things like coffee is not a good goal. It should be for much larger transactions, but optimized for decentralization and sound money.

Derivative blockchains can be spun off of Bitcoin, and settled periodically to the "reference" blockchain, which is Bitcoin, through lightning networks or other off chain developments (perhaps some sort of forked derivative pegged chains).

Bitcoin only has value as either a distributed non-centrally controlled international settlement network for countries and large banks [0], and/or as a digital Gold.

Optimizing this value out of bitcoin to achieve transaction throughput destroys the necessity of Bitcoin for existing.

Bitcoin proper should remain resistant to change, distributed, unable to be coopted or controlled by a few organizations, and above all, to have the properties of sound money (so resistant to changes to expand the money supply). If it doesn't have these qualities, it has no reason to be valuable. It cannot be all things to all people, but it can to "one" thing very well.

Steam accepts bitcoin.

Quite a few domain/web hosting/VPS companies accept it, like Namecheap and Namesilo.

Online gambling sites accept it for obvious reasons.

It's hardly ubiquitous, but for some things it's fairly practical.

> In China however, they throw away that pride of creating the greatest and shiniest.

Why is it every time china is discussed, people have to repeat the same trite false things.

China is a developing nation. Developing nations don't create the "greatest and shiniest" things. The US didn't create the greatest and shiniest things when we were developing. Germany didn't create the greatest and shiniest things when they were developing. The same thing with Japan. The same thing with Korea.

There was a time when american goods were considered shoddy and poor quality. There was a time when german goods were considered low-end. Japanese goods were mocked for being low quality. Korean goods the same.

>The way I see it, we have democracy in politics but in products, its authoritarian because its guided by the billionaires and wealthy. In China, they have an authoritarian political system, but democratic economy space because they can actually vote with their wallets.

Right. Because in the US we can't vote with our wallets.

I say this without an ounce of hyperbole: I assume all ICOs are a scam until convinced otherwise.

The majority aren't outright scams (willful intent to defraud), but most are capital grabs with virtually no chance of being successful businesses.
Facebook or Amazon may have a say in that, a lot of those 1 in 4 bytes are video from Youtube.

That said, those bytes still need to be delivered, Google really don't have peers in this stuff, apart from maybe Facebook.
Yeah testing needs to be done with compiled code on target card otherwise you can't be sure it works. Usually compiling code is super strict no further optimization then the standard can be used etc. Only specific cards and compilers are "trusted" to use.

The entire point of Cryptocurrency is to step away from institutional trust, not dive head-first into it.

Bitcoin succeeds as a scarce and sovereign wealth management tool but once you give away the private keys, you lose those advantages.
A friend of mine invited me to help him start a non profit to apply natural language processing to detect violent rhetoric and bullying.

This was while I was working as a utility programmer and going to grad school.

While it never panned out for a number of reasons, it did get me introduced to the world of prototyping and I never looked back.

There have certainly been times of instability and there is no one there to lend a hand most times which can be intimidating.

One thing I try to do to get past the anxiety is make a new personal project when things get rough. So far it's worked out that those projects often lead to new opportunities and skills.

Being able to write the device, server and web client myself allows me to build concepts rapidly.
There are quite a few other tools for protocol verification (ProVerif, Maude-NPA, etc.) and I haven't used all of them myself, but I think Tamarin is particularly easy to read and understand even when starting out. The rules are roughly written in terms of inputs to outputs along with some labels to refer to what happened, and the properties are essentially just plain first-order logic. (Disclaimer: I'm biased, I've worked with Tamarin more than other tools and also contributed some to its codebase.)

Also I think part of the power in using Tamarin is that if it's having trouble proving something automatically, it's easy to jump in and try to prove it manually with a relatively straightforward graphical representation of the trace sets. That also helps you spot any potential interim properties you might need to prove as helper lemmas, etc.

It's gotten some recent popularity for the work on TLS 1.3 as well [0], and with that an effort to improve the materials available for people to pick it up themselves [1, 2]. Some of the things we did to nudge Tamarin's heuristic in the right direction when autoproving the WireGuard model (documented in the .m4 file) are getting baked in to Tamarin soon.

(For what it's worth, you don't actually have to deal with any Haskell unless you're planning on modifying the prover, the protocol models are in their own language.)

Washing for recycling doesn't have to be nearly as thorough or sanitary as washing for reuse though. And yeah that might work for Amazon but no one else has the infrastructure to do local delivery like that. Even with whole foods local they'll still probably need to expand staff or food prep areas to make it work.

I agree that those have bigger bangs, but the "buck" part for vaccines is extremely small. Good plumbing and sewers have probably saved a lot more lives, but the cost per person is orders of magnitude higher.

For example, the cost of eradicating smallpox was about $1-2 billion (in 2017 dollars), and saves around 2 million lives per year. (This is a rare example of a one-time investment that pays off forever with no additional action on our part, which is pretty nice.) This is about what New York City spends annually to maintain city water and sewer infrastructure.

"Predatory" lending is only possible in the presence of coercion.

If Party A is such a bad credit risk that the only loan they can get is from Party B at a high interest rate, and that requires them to dramatically change the behavior that created the cash crisis in the first place, Party B is not a predator.

If Party B is charging too much for the loan, surely another "greedy" party will undercut them and offer better terms to Party A.

If Party A accepts the debt on the same conditions, but then fails to dramatically change their behavior such that they insist the terms of the original deal be modified or else they'll default, Party A is acting like the predator.

Sure sounds like a hack to me.

Is there any reason for the Bitcoin being worth anything? Even in North Korea or Cuba it is easier to hold USD than Bitcoin. I'm sorry for the late investors, but people was warned since long ago.
Maybe? Depends on how it shakes out. Now is certainly the time to speculate, you've got probably a 1/3 chance of making money off it. The three possible outcomes would be, a) bitcoin never recovers, you lose the money you're speculating with, b) bitcoin recovers and you picked the winning side, congratulations, you bet when everyone was running away and it payed off, or c) bitcoin recovers, but you picked the losing side, you lost your money.

Should you be "investing" in bitcoin right now? Absolutely not, that's a stupid investment, but so far as gambles go there are worse odds.
I was talking about this last week. I called it the MySpace/stylesheet paradox. MySpace got it wrong, Facebook and Gmail got it right.

> In the days of MySpace, people would tweak their personal profile so it was presented to every visitor using the colors, sounds, typeface, text size, and other styles that the profile owner found most pleasing. This gets it exactly backwards: out of everybody's opinions about what a user's profile needs, it's the profile owner's opinion which matters the least. After all, the profile owner doesn't spend his or her time reading his or her own profile—the profile is for other people, and we can see this by looking at what the profile owner does do, which is to spend his or her time reading everybody else's profiles.
I think you understate the cons of the on-chain solutions. This said as a big-blocker myself.

I think the size of the node is a consideration, but not a huge one -- before we started butting up against the limit, blocks were naturally much smaller than the 1MB limit -- the fear of spam and dust transactions never materialized, so there's no reason to expect that the economics are fundamentally different now.

The biggest con by far is the hard-forking nature of the change. Changing the limit means that clients will have to accept blocks that they currently don't accept. This applies to core, of course, but also to the innumerable other implementations of the bitcoin protocol. Don't make the mistake of thinking that core is the only player here -- a hard fork is trouble for everyone, miners included, and has a substantial risk of causing two viable chains to appear, which is much more of a disaster for Bitcoin (because of how long it takes to adjust difficulty) than it was for Ethereum. With sufficient consensus, this becomes less of a problem for the same reason -- the defunct 5% chain (with 95% consensus) will take 280 days to converge on a new difficulty, during which time that network will be extremely congested. But if miners are misconfigured, etc., even if there is consensus there may be an unintentional hard fork.

The second biggest problem is the rise in the risk of orphaned blocks. This, I think, is probably what holds most miners back -- the longer it takes to transmit and verify a block, the greater the chance of a block being orphaned is. Orphans hurt the security of the network by making it so that a smaller fraction of the net hashing power is actually being applied to the problem of securing the network. As much as people complain that the proof-of-work is "wasteful" in the ecological sense, wasting even that wasted work would make nobody happy.

Segwit, on the other side of the debate, has the attachment to off-chain scaling, but also offers a solution to transaction malleability, which is a huge problem for bitcoin businesses as it can be difficult to tell whether a transaction ever made it to the network, much less rely on features like child-pays-for-parent. Since the current version of segwit is a soft fork, it should, in theory, work with existing non-core clients, and the Litecoin adoption should give us some information on how that works in practice, but Litecoin doesn't have nearly the adoption that Bitcoin does, so it's hard to generalize.
As I often told my friends, go to a company like Netflix. Netflix actually tries very hard to make money not a concern to its employees, and they do hell of a great job.

I don't think you'll find a better group of books for $15, if your goal is to learn about security in general.

Most of the stuff here is general crypto, which is very helpful with respect to just learning about computer security, though not necessarily focused on securing something like nginx specifically. You'll learn a lot more about security in general though, which will make it easier to learn about security specific platforms.

I can't recommend this collection enough. I'd make the purchase, then dive into a couple and read whatever you find most interesting. I don't believe any will have the top keys of security technology X, Y, or Z. But you'll learn a lot in general, and it will be much easier to read other security how-tos and tutorials on locking down specific platforms.
it is great for money laundering which is why it is so popular in china. You can buy btc in cash no questions asked and it is untraceble and then sell it at a legit exchange in another country and claim it as legit income or just move it from country to country bypassing currency controls in places like china where no bank will allow you to send more than 50k USD per year out of the country
The nylon lines are only a safety system - there's typically a mainline and then only branches off of it. The only time multiple lines are used are at the entrance (the mainline is usually placed 50-100m back to prevent untrained divers from finding it accidentally) or where there are jumps, and in both cases the temporary connections are retrieved when the team of divers exits.

In some higher traffic caves these lines are replaced regularly, however with most caves it's an every couple of year type situation and done by volunteer teams.

As a cave is explored & mapped, line is tied on to the end from the explorer's reels - adding multiple knots and failure points. Once there's sufficient traffic or need usually caretakers will go through and attach more resilient line (usually a spectra or dyneema line) and take out the original line, only leaving the exploration markers (name, date, expedition, etc). These teams also find more permanent attachment points or add them (using silt anchors and sometimes bolts) so that the lines aren't secured to cave features wherever possible.

Adding & removing lines on each dive would actually cause more damage to cave features than keeping a permanent or semi-permanent line in place, and there'd be a much higher risk of line movement and entrapment as the connections would be fewer and further between.
https://www.rabb.it/ let's you do this. They advertise about letting you watch Netflix, Hulu, Crunchyroll, and anything else with your friends. It seems to be just streaming the user host's screen to anyone else in the room. I'm not sure how legal that is.
Legal: No. These are copyrighted works after all.

That said, If you have a laser printer it is probably cheapest to print it yourself. Buy paper that already has the three holes in it for the binder.

Still probably near the price of buying the actual books.

Edit: And if you still want to have there be a bit of a charity tie-in, the Amazon smiles program smile.amazon.com has a lot of charitable organizations to choose from.
i love the transmuted theology :P
'I think 90+% of people would think that an asteroid with a diameter of two miles would weigh 14e8 * density'

If this where YouTube then you might be right, but I would assume the vast majority of people here understand the r^3 part of the formula for a sphere especially when it was included in the same comment. Though they may forget about the 4/3.

And again, it's perfectly valid English to say a mile when you mean exactly 1 mile. AKA "> How much does a mile weigh?" replace that with "How many feet are in a mile." and someone saying 5280 is being reasonable by answering the question.

PS: Now if the original question was per mile then I would agree with you.
>(and most games aren't AAA)
You're right, but AAA sells make up the biggest fraction of game sales. Why should I buy a Mac for gaming if I can't play games like Call of Duty, Overwatch, GTA V or The Witcher 3? AA and Indie games are a niche market, not driving factors.

There is also a factor that you can't really blame on anyone: OS market share. Even if more Mac (and Linux) users would buy games, the time worked on porting and support would likely still result in a net loss.
Now people is panicking, so it is likely that the sooner you sell, the better.
Interning with the Contactually Engineering Team
So I have google fiber. And as you note this relies on your connection. But that's only half the issue. Since getting google fiber I've realized since my pipe is no longer the issue that the service I'm connecting to is the issue. All the latency and lag and bandwidth limits I have are coming from the servers themselves and their less than stellar capacity.
>There's something about employment ... that leads to a certain form of inauthenticity.

Potentially the most profitable. There's plenty of net negative value content out there, too.
I don't think so. There's an incredibly important art and science to model selection that is not encapsulated in curve fitting. For example, say we observe a boy throwing a ball and we want to predict where the ball will land. From basic physics, we know the model is `y = 0.5 a t^2 + v0 t + y0` where `a` is the acceleration due to gravity, `v0` is the initial velocity, and `y0` is the initial height. After observing one or two thrown balls, even with error, we can estimate the parameters `a`, `v0`, and `y0` relatively well. Alternatively, we could apply a generic machine learning model to this problem. Eventually, it will work, but how much more data do we need? How many additional parameters do we need? Do the machine learning parameters have physical meaning like those in the original model? In this case, I contend the original model is superior.

Now, certainly, there are cases where we don't have a good or known model and machine learning is an extremely important tool for analyzing these cases. However, the process of making this determination and choosing what model to use is not solved by curve fitting or machine learning. This is a decision made by a person. Perhaps some day that will change, and that will be a major advance in intelligent systems, but we don't have that now and it's not clear to me how extending existing methods will lead us there.

Basically, I agree with the sentiment of the grandparent post. Machine learning is largely just curve fitting. How and when to apply a machine learning model vs another model is currently a decision left up to the user.
I'm an Android and Ruby on Rails dev and I've been working as a freelance for a couple of years now.

I am making quadruple the amount my peers are making in Eastern Europe while working less hours and remotely.

Most clients I get is through networks such as Toptal, which I would wholeheartedly recommend. I'm also a member of Gigster, which I can't quite recommend at the moment, and there is CodeControl and Povio labs which I would also recommend.

I think the best approach is to sign up for a number of these networks. It will definitely kickstart your freelance career and will help you have a constant stream of potential projects and offers.

However, do avoid websites such as Upwork or other networks which don't have a technical interview process as these are very likely flooded with extremely low-wage and/or low-quality workers. It is much harder to land a good client on these websites.

Here's my Toptal referral link: https://www.toptal.com/#work-with-the-best-programmers-today

But again, don't just apply there :)

Is it just me, or is charging pennies per gigabyte usurious? If I paid even a penny per gig on my home internet, I'd have nearly a $150 bill just in gig charges, and I know I'm one of the lower bandwidth customers on my block.

Why stay with a host that bends you over a barrel for transit? Even Netflix doesn't use Amazon to deliver their data heavy content, as their pricing is pie in the sky high.
Yep, this is akin to the Freakonomics "why don't real estate agents always push for the highest sales price" question. The gist being, it's a numbers game for them. The extra 5-10k they negotiate when selling your house makes a small difference in their commission, and usually comes at a disproportionate cost - either risk of the deal falling through, or time spent in negotiations that could have been better spent moving on to the next deal. It wouldn't surprise me if recruiters face a similar calculus (time spent negotiating on your behalf, risk of damaging their relationship with the company, etc.), and would definitely agree that at the end of it, you have to be responsible for your own outcomes, because no one else will be.
If you believe that cryptocurrency will be part of our future, then yes. Otherwise, I don't know. There's also Ethereum and many other alt coins with a total market cap of over $70 billion https://coinmarketcap.com/ .

> Secondly, the consensus amongst Core developers, as I read it, is they want as much on-chain as possible. Their definition of possible is what can a Bitcoin client handle on the average user's PC

I'm curious if you have some sources on this -- most of the anti-big-block claims that I have seen tend to settle on the hard fork being problematic, which is a very legitimate criticism (thought I need to dig up citations to play by my own rules here). There's also a significant group (I think unaffiliated with Core) that worries about the increase in orphanage that big blocks can lead to.
Is there a field that does not discount domain knowledge? Or is that just "judgment" and custom analysis? I am trying to understand how all fields map together. Thank you.
Cave-divers are expected (and taught) to carry reserve gas supplies with them. From the description, they had reserve supplies - enough reserves to search for an hour - but failed to recover their guideline within that time.

The issue was that they lost their guide-line leading to the exit, rather than running out of gas. In such a scenario, no amount of reserve caches could really solve that problem.
