Person A mines 1 BTC. Since a Bitcoin has no intrinsic value (as distinguished from market value), Person A has not created any value. They have created $0 worth of goods.

Person A sells their coin to Person B for $1,000. A is $1,000 richer and B is $1,000 poorer.

B sells the bitcoin to C for $2,000. A is still $1k richer, B is $1k richer, and C is $2k in the hole.

C sells to D for $3k. A, B, and C are all $1k richer, but D is out $3k.

At no point in the chain is any actual value created or destroyed; it merely changes hands. So even though the price keeps going up, the total value across all participants never goes up. The sum of the gains and losses of all participants is $0.

(Note that I'm using "$" to represent a generic indicator of value. Feel free to substitute € or ¥ or gold or shares of Facebook stock or whatever.)

===============

There are two simplifying assumptions above, both of which make Bitcoin not exactly zero sum.

Good news first. Bitcoin can and does create some value in the same way that other currencies do: by facilitating mutually beneficial exchanges of goods and services. Commercial use appears to only be a tiny fraction of all Bitcoin transactions (and an even smaller fraction that wouldn't have been facilitated anyway using some other means of exchange), but it does happen so credit where credit's due.

The bad news, though, is that all of the above requires electricity. A lot of electricity, as it turns out. Both the initial mining and every transaction thereafter require someone, somewhere to burn some amount of power in order to generate proof of work. Since proof of work is explicitly designed to be useless, all that spent power is essentially deadweight loss.

I haven't seen any good numbers on the first recently (and I would love to have my assumptions proven wrong), but given the ginormous estimates of electricity consumed by the second I have a hard time believing the network as a whole isn't substantially worse than zero sum.
One could also just use one file with multiple YAML objects delimited by “\n—-\n”. The Kedge stuff looks moderately interesting, and I definitely would have found it useful a year ago. Now, though, I seem to have developed a begrudging admiration for the “native” YAML format. Maybe it’s Stockholm Syndrome, but once I finally began to understand Kubernetes I began to find the verbose YAML format to be a benefit rather than a barrier.

> early adopters, which take on more risk

I don't want to get into the debate on the definition of a pyramid scheme, but what was anyone risking by mining bitcoins for essentially nothing in 2009-2010?
I don't quite understand how this works. WhatsApp web just lets you access your messages on a different device, it doesn't let you register an individual account or anything. Surely that means this people already have a phone that has WhatsApp? Why not just use that instead of this complex workaround to get it on the other phone?

The false sense of security is what WPA2 gives anyway. Coffee house has a password on their wifi? Great, then only someone with the password can impersonate the AP, which is only... everyone.

You can't tell everybody something and still use it as a secret.

What they should be doing is putting the public key of the AP on the wall as a QR code.

Or the real solution, which is for everything to be end-to-end encrypted regardless.
I'll probably be skipping this one, but will definitely be purchasing the knuckle controllers and the wireless adapter. The screen-door-effect and lense artifacts aren't as much of a bother as the cable, and the knuckle controllers genuinely seem like Gen2 rather than a mere resolution bump.

As someone on HN once said, we won't discuss the core of the problem not because what he said is untrue, but because the outcome of discussion may hurt peoples' feelings, and this is not the right thing to do...

I see their point, but there is a way of discussing it in a way that would minimize this risk. On the other hand, if you have some assumptions and consider their negation offensive, it's very difficult to have any form of conversation.
Some see enormous value in an mathematically defined, uncensorable, permissionless, trustless, programmable, digital currency.
That's too bad. The light bleeding makes playing games like Elite Dangerous really cumbersome. You can even dial down the cockpit LED brightness but that doesn't help with the bleeding. Because then the LEDs are too dull to read everything allright. Since the game plays mostly in space and the only light sources are the cockpit LEDs makes this problem really stand out.

Also, the general blurryness of everything outside of the center of the lenses make racing games way less fun than they are supposed to be. Everyone who drives in teh real world knows you keep your head mostly in one position and then peek down by moving your pupils to take a short glance at your instruments or the mirrors. All you see with the Vive is a blurry mess unless you move your entire head down until the intruments are dead center of your field of view. Not really the realism one would expect from a VR racing game, imho.

All this is just too bad. Because I think while roomscale is pretty neat it is still very much work to set up. I mean by clearing your room, moving furiture etc. And then you still don't get to act freely because you will always know that you can't go very far because you would run into something. Kinda immersion breaking if you ask me.
But where VR could really shine is with cockpit simulation games. No furniture moving needed. Just sit down, put the VR goggles on and of you go. Too bad that the light bleeding and the off center blurryness hinders this at the moment. Heres hoping this will be changed in the future.

Planting a Backdoor – Using Netcat TechyTalk.Online
The likely reason Bitcoin has been taking off in China is because the available traditional investing options for people there are terrible as a result of government meddling. In particular, the whole country's economy is in the middle of a terrifying debt-fuelled bubble in which bank lending has effectively become an arm of the state, leading to a rather terrifying debt-to-GDP ratio and a banking system that may well collapse the moment the growth pauses. Combine that with increasingly strict capital controls that restrict the ability of most people to invest their money outside of China and a lack of trust in the government not to seize less favoured people's businesses for the benefit of insiders, and you have a strong recipe for Bitcoin popularity.

According to Google cache, the robots.txt file and sitemap, it used to be a WordPress-powered link directory that you could pay to submit a link to and purported to offer "authority" to boost your search engine rankings. At some point recently, they probably threw an "exit" or "die()" into the index file: all the pages are there but returning no content. The millions of links were likely created by the site's owner's own other sites/domains; a spammy link network to game search engines again. There's tons of link and content farms like this out there trying to manipulate Google search results.
You’re recommending that the general public engage in consuming LSD. This is so incredibly irresponsible that I’m at a loss of words. Simply, there’s no reliable way to assess whether someone will have a bad reaction. Your recommendations for assessing safety are not reliable. And, trips are a one-way journey. You’ll never be the same after you trip.

Just keep in mind that you’re getting advice from someone who has already fried his/her brain on acid, and isn’t in any position to say whether that crap will affect you in any bad way, and they certainly don’t care, despite carefully framing their bad advice. This person is interested in “enlightening” as many people as possible, and his/her friends will disembowel you because there’s “twelve” of them. Quite simply, some people have a brain chemistry that doesn’t mix well at all with LSD.

You’re really irresponsible for posting this. Shame on you. How dare you post such a recommendation. Someone could listen to your advice here, think that because they’re stable that they’re safe, have a bad reaction and never quite be the same.

That garbage is pure evil poison for some, and one simply has no way of ensuring they won’t have a bad reaction, regardless of whether they are stable or not. One will never be the same after dosing, for better or worse. Johnny 95 IQ quarterback might not be profoundly impacted, but a typical nerd with an already creative mind will certainly have a life changing experience, and such changes are not always roses for all, despite your anecdotes.

I am cognizant of the fact that my viewpoint on this subject is not the norm in these parts, but someone needs to offer a responsible counterbalance. I recommend that most people do not try LSD at all.

Unless you are the Internet provider … And I do believe that Internet providers in China would answer to Chinese government requests without troubles (I doubt they would sue the government like they would in the US).
I recently looked at jobs in the Bay Area. I currently live in Southern California, so it's not cheap where I live. To have a sub 20 minute commute (current commute: 7 minutes) to any of the jobs I was looking at would have added about $40k per year in costs. I probably could have been able to get an offer at $40k more per year, but it would be moving the whole family to break even financially.

If I could talk my wife into living somewhere with winters, then we'd probably move to Cincinnati, since we have friends there. At my current pay we could probably retire there when the kids are in HS.
After you write each email, and before you hit 'send':

1. Split any long sentences.

2. Identify any list-like information (anything with multiple 'ands' or 'ors' or commas) and turn those into bulleted or numbered lists.

3. Summarise what you want the person to do in a short sentences at the beginning of the email.

4. Go through the rest of the email and delete anything that the person isn't going to need, in order to do the thing specified in (3).

5. Now think about it from the reader's perspective. If they get this email and read it from start to finish. What are they going to do in the next 15 seconds? After you empathise with them, you may want to add/remove some more info.
and rightly so! the boom of ICO's is proof of concept if I've ever seen it, even though almost every single one is a scam as far as I've seen. I've had to discourage friends from investing in obvious scam ICO's, unfortunately. And my mother who is the most gullible sucker ever.

It's pretty strange to see people so consumed with it. It reminds me of beanie babies, and my horrible step-grandmother who would send me in to buy them once she had hit her limit. She was an awful speculator and probably has a worthless collection today for all the money she spent on ebay back then. She'd drive to Vegas to buy them, neighboring towns, all over the place. Totally consumed by speculation gambling. It sickens a person to see someone so...lost in that temptation. I'm not sure how else to put it.

Also due to house vs. lot-size restrictions the house would have been limited to just over 2000 square feet. This is regardless of the number of stories (i.e. a 2-storey house would need to have about a 1000 square foot footprint, but a ranch could have about 2000 square foot footprint).
Sigh. Please! Think, don't just react. I'm not criticizing Canada!!

> when they're in season, lettuce, squash, beans, corn, wheat, any of the usual staples.

What do you eat the rest of the year? That's the question. It's not a question on the ability of Canada to grow food.

If you only ate local, you are extremely constrained in what you can eat because things are only in season for a short time.

An additional question is: Where is the best place to grow a particular food?

For example, you mentioned Winter Wheat. Perfect! Grow that, and livestock, in Canada, and don't grow Wheat in Florida. Instead Ship Food! Let Florida grow oranges, and Canada grow Wheat, then trade, and get rid of this "local" nonsense.

> I don't know what your point is other than blathering on about total nonsense regarding maple syrup and seals.

Do you understand my point now? Or do you still think I'm somehow criticizing Canada?

By growing food in the best place for it you can save a ton of energy and fertilizer. Eat local is bad for the environment because it uses more resources, and because it forces people to have restricted diets.

They seems to be registered at "Directi Web Technology Pvt. Ltd" which is a domain register.

It also doesn't say it is the top sites in the world as in visited. It just says that these are the sites being linked to by other sites (in the root dir).

Feels to me that this company set up 1.6 million websites all having links to these URLs. Because they all have the same amount of websites linking to them.

As for the reason I have not the slightest idea.

On a more serious note: I don't think that there is some significant astroturfing going on. Both companies built a very shiney (and possibly over-inflated) PR image for themselves, with a zealot following, which is bound to annoy some people at some point. Those people than take any chance of a slip-up to try to make that PR bubble pop.
They went a little overboard with this, just my 2 cents.

Ps. Why flagged? :S
The proof of work needs to be “useless” in order for it to protect the blockchain (there are proposals that dispute this, and I won’t claim to be an expert, but that’s the fundamental idea behind Bitcoin).

When you say that the net value is negative even if the network itself has some positive benefit, what is the negative component there? The only negative component of all that electricity usage is externalities, which apply equally to each unit of energy regardless of what it is used for. Pricing externalities into the cost of electricity is obviously something I approve of, but that’s a separate issue, and I doubt the externalities of electricity usage are anywhere near the magnitude of the positive impact of bitcoin.
When doing my PhD, I was working in a research center which was open 24/7.
I would go to work at 14, starting with a lunch at the cafeteria. Then hopped to buy some groceries. By 17 a lot of people were gone and I could start to really work through the evening and the night, until about 5 am when the sun was raising - which was the signal to go to bed.

I felt like a vampire, had zero social life but did fantastic work.

The main thing was that I knew it would be temporary and not sustainable, which also made me very happy (it was a fun experience, au from family and friends, and I knew I would be back to normal life soon).
Of course, many of the early adopters got very lucky while taking almost no risk. This happens with gold and oil too. However, those that chose to hodl started taking real risks as soon as Bitcoin hit 1$. Bitcoin hodlers today are obviously taking substantial risk as the price could drop massively at any moment.

That's the trap of Go. None of these are deal breakers. Yet.

It's notable that the vast majority of the above are complaints by experienced developers working on large projects that need to be maintained and expanded for years. They're not the sort of thing you notice over a weekend of tinkering on something fun, and they're not the sort of issues that beginners will run into under any normal circumstances.

All of that adds up to a honeypot for newcomers. The language has some deep issues, but they're not the kind of things you're likely to notice until you already have 200k lines written and it's too late to switch to something with a steeper learning curve. Saving two weeks of confusion when you're learning ends up causing a lifetime of headaches down the road once you're an expert.

In other words, Go is PHP for systems programmers.
A critical problem I see that needs solving is the Starbucks style open wifi login pages that fail to redirect when trying to visit HTTPS sites.

A new secure authentication system is needed for these set ups.

I’m blanking on the name of them but clearly they are widely deployed and likely causing lots of regular people to have trouble connecting to pages because they tried to connect to Facebook instead of an HTTP site.
For Dengue fever, aspirin can be fatal:

"infecting organism in dengue affects the platelets which are responsible for clotting (stopping bleeding) increasing the tendency of the person to bleed. Aspirin and Ibuprofen also have similar action. Both of them together could cause the person to bleed excessively pushing the patient into what is called the ‘Dengue Shock syndrome’. And once in this stage, medical treatment is needed in an emergency basis and hospitalization becomes necessary"
