> Is there not a way to test generators without actually having them power the live datacenter infrastructure? I mean, simulate the exact generation and load requirements that the generators will face?

That would exercise transfer switches in addition to generators. Transfer switches are always energized, except for the time an equivalent of a big red mechanical switch is flipped into "OFF" position. When it is in the off position, neither main or generator are going to provide power to the customer. The biggest power consumer is actually a cooling system. If a HVAC system stops functioning in a typical data center, the temperature would quickly rise to the level of Arizona desert, destroying metric tons of equipment. Transfer switches have certain properties where after a flip they may not go back to the correct state on power restore ( say 1% ). Normally it is not a big deal because you really need to have lose power under full load often to get bit by it and if you are losing power that much you should probably address it with the utility company. However, if you are doing your full test once a week, in one year you would introduce 52 power failures.

Say your transfer switch is stuck in a wrong position. Now you need to shutdown all heat generating equipment to when you drop power to fix/replace the failed component you don't melt your data center... Congratulations, your data center now has to go offline.
The title feels very clickbatey. I did overlook the Show HN part but thought it was going to be an interesting article, not an event system for emails.
The article makes a valid point. Everyone can not possibly sell all of their Bitcoin, and if they tried, it would be defined as a crash. I would be lying if I said I wasn’t worried about this.

But I think it’s wrong to think of Bitcoin as a commodity, or that it needs some killer application. I really think Bitcoin is best thought of as a currency. Fiat currencies work because as a whole, we agree on its value. Usually, it’s backed by a country’s government, which represents the country’s populace. It’s value is inherently determined by the size of their economy.

Right now, Bitcoin isn’t backed by a government at all, but it’s still backed by people. Those people obviously feel that Bitcoin is worth what it is today. Of course, that can change, just like any currency.

But eventually, Bitcoin will reach a value high enough that more and more people will start accepting it alongside fiat. I mean, go to any border town along the Canada-U.S. border, and they all accept USD and CAD. Clearly, they do that because it’s advantageous to attract customers. That could eventually happen with Bitcoin. Then we’ll stop worrying about Bitcoin’s valuation so much, insofar as we stop worrying about the values of fiat currencies. It matters, but not that much.

When that will happen, and at what value, I have no idea. But until then, I’m hodling.
Ah sure. But for those cases you can always drop to a normal session with:

Honestly, a lot of the CS/delivery issues are somewhat dependent upon the consumer market that the company targets. Some communities are very word-of-mouth and reputation based. One of the ones I'm involved in is the firearm community, which is very much that way. Places that have bad CS or delivery issues get lambasted and are very affected by said issues, and those that go out of their way to help and assist their customers are hoisted far above.

You are correct: http://www.bbc.co.uk/news/technology-25330615
This is the general rule of thumb for `var` in C# that I've seen, which has similar issues to `auto` in C++.

That said, there are awful compiler inferred types that C# doesn't have, so `auto` has a much wider application than `var` does.
If they were so invested they'd be reading the thread for people who are communicating about the topic. For people who are referring to comments or quoting other posts or didn't specifically @mention to drag a person back to look STRAIGHT AWAY lest they lose engagement.

@mentions on forums are good UX in the way that twitter @mentions are good UX - they drive clicks and opens - not engagement. They don't push good content, good conversations, good experiences. They allow people to sandbox discussions, to talk across each other. To skip volumes of content to just get their little piece.

Having the feature degrades the forum community imo, irrespective of who does and does not use it.

I'm a guy who likes old school forums though, so, you know, my opinion is probably not worth that much ;)
I'd love (love!) for the answer to all questions about addiction to be "suffer your own consequences," but the US exists as a massive welfare state where intelligent and conscientious citizens should try to ensure that the investments they're making in the lower classes are going to better use than heroin and acting as proxy votes to foreign regimes in US elections.

But we're not even close to a libertarian enough nation to just ignore the problems that corporations create for our citizens, even if those problems could be avoided by personal responsibility. And "soul searching" is waaaay too far up Maslow's hierarchy for most US citizens to even start considering.
y'all upset because you don't own bitcoins. Keep telling me it will crash, write long articles about it, all while I get rich.
You are probably right but I think it's good form to at least skim an article before commenting on it. Without that we just reinforce our preconceived notions.
The official diagno tutorial is a pretty good start, followed by Tango With Django. That, combined with your previous experience + Django's documentation should be enough to get you going!
The hubris Bitcoiners carry is completely different. The net started among academic wonks and University faculty pages. Bitcoiners purport to bring down Central banks and subvert the state, delivering a new social order.
I really love Ethereum and have been invested in it for a while. I think @vbuterin and crew have a clear idea as to how to move past problems, and I find it exciting to watch the Ethereum foundation execute their vision well.

Bitcoin, on the other hand, doesn't perform its simple functions well in the short term, and seems to have very little idea on how to scale long term:

1. Transactions are still pretty expensive and take a good while to settle.

2. Proof of work as a long term consensus strategy just doesn't work. The amount of energy required to mint transactions is immense.

3. Bitcoin hasn't made the headway with corporate partnerships that I think will be critical for larger adoption.

On Ethereum's end: a movement to proof of stake, sharding with global consensus, and the corresponding lightening and whisper networks all are really exciting domains of exploration. My two primary worries here are:

1. There has not been much work yet to bring well designed languages to the EVM at this point. Well designed languages, with good testing frameworks (QuickCheck from the Haskell landscape comes to mind), and formally verified fundamentals (e.g. wallets) are critical for contracts to be viable for anything other than playthings.

2. I worry about regulation totally hammering down innovation in this arena before it can sufficiently get past the rough early days. I do cautiously applaud Russia's hesitance to regulate, in an attempt to avoid destroying innovation.

On (1), I would love to get involved writing adapters for languages or subsets of languages like OCaml or Haskell to compile down to the EVM. If anyone knows of any resources I could jump into to explore this type of project, I would love it if you linked them.
I mean, most things I don't need to sign for and I can just pick them up on my doorstep when I get home, which is way more convenient than that.
A car analogies, the best ones!

If your car breaks down there are other means of transportation like getting a Uber, renting a car, carpooling, riding a bicycle or even walking. This is the typical "infinite" possibilities situation where capitalism really blossoms. I personally don't own a car because exactly all of those reasons, so I chose to never have a car that I need to repair. I hate things to maintain.

Now imagine a situation where you are only allowed to go to your work in a car, nothing else. If you don't go to your work you will be fired and you will never find another job again (i.e. dead). And the spare part you need for it to get it working again is only available through one source that for some reason charges about 100 times more than it takes to manufacture the part itself. You are not allowed to have any other car than the one you currently own, not even the same one new.

Now that's how having cancer works in the field of choice.

People choose to live near volcanoes, mountains, oceans. Places where tornadoes are frequent. There's a good reason most people on Earth never saw one.

Though I agree somewhat on most of your points. Actually one of the biggest problems is that nor the legal opioids nor heroin are freely available towards consumers. A lot of people are killed because impurities or more unhealthy alternatives. Again, mixing pure capitalism without the real choice makes things really ugly.

But there's a huge incentive to make money not on the best solution for the patient but based on the largest kickback for the doctor and the biggest profit margins for the industry.
That's similar to the argument that "blockchain good, Bitcoin bad".

Bitcoin is the killer app. Similarly, the internet is great not because of TCP, but because of the information (which is what gives it value).

A. No. If you receive merchandise that you didn’t order, you have a legal right to keep it as a free gift.

I think the main industry there is tourism. If there are any Dutch speaking callcenters there they aren't very common, I've never encountered it in real life (you'd instantly notice by the accent).
yes, but painting things as antiquated and past-tense when they are actively still practiced by literally millions in other, modern cultures, is a sign of a hugely flawed and self serving editorial bias.. hence critique.
I was having a conversation about bitcoin, and I was saying the fact that the price goes up so fast means people cant/wont actually use it as a currency. I think someone bought a pizza with 10k bitcoin? thats now 70 million $. Even in the last year it has moved up so fast, and if people think it will continue to grow 'because of adoption', people cant actually 'adopt' it and use it as a currency, because todays bitcoin is worth a lot less than tomorrows.

then i realized, i was describing deflation.

I experienced the receptionist losing track of my stuff once and it was a really uncomfortable situation because, obviously, you're still colleagues and you don't want to get too pushy, but at the same time, where the hell is the stuff I paid for? After that I stopped having stuff delivered to my office.

And anyway you may not want everyone to know what you are buying.
I got up to get something to eat and the restaurant I wanted to eat at couldn't open because a group of heroin addicts outside sleeping on the steps refused to move until they were given food.

>He was under no moral obligation to fix Nintendo's mistake for them.

He was under no legal obligation. But it was the moral thing to do.
Exactly. In my head I like having the free lottery ticket more than having $100. But in my ledger they are not present as an asset.
If they are well off already then they, as individuals, are well off which has nothing to do with whether they are founders or not. Rich people have more options than poor people.

There are rich people who work at companies too who won't be bothered by failure while the founder who came from nothing will be hurt.

>It didn’t take long to arrive — but when it did, I noticed some damage to the outside of the packaging

Author signed off on a visibly destroyed package. This is where support stops in my country(also EU). Standard procedure is to either refuse damaged package, or open with courier as a witness and make damage protocol, documented with pictures. The fact Nintendo agreed to replace it on faith alone is quite good, pestering them with phone calls all week combined with fact they somehow send two units probably flagged him as a potential fraud.
The wages are also very low for computer programming compared to the US, despite a cost of living that is not much lower.
Well considering the amount of forums on the net where you can't even mention bitcoin without everyone who holds it swarming you - "Buy the dip", "This is good for bitcoin", etc. - I'd say everyone is pretty aware of the positives behind bitcoin and isn't too interested in hearing them regurgitated from yet another evangelist.
Some businesses rely heavily on FB and other social media for getting customers. Other people only get family updates from it. It's getting harder and harder to "just don't use" social media.

Is it not possible to have stuff shipped to our workplace address. I've been doing that for years.
The clear answer to that would be only you can revoke the certificate either by signing or by going to something like the post office/DMV with 1-2 additional pieces of ID (for cases where your card is lost/stolen). Also the cert is only for SSN like things and proving your identity in those cases not that you're not a citizen if your cert is out of date. So you couldn't say open a new bank account or apply for a new loan but everything else just keeps working.

I got dire warnings from my neighbor when I bought my house that package thieves were on the loose (along with warnings about coyotes and heroin addicts). So far the packages have been fine and I haven't seen any coyotes or heroin addicts either, so hopefully my run of good luck continues.
Bitcoin is good.
Flawed argument because he doesn't understand the tech.

> The only exception that I can think off is that if it becomes a necessary component of smart contracts, it could take on the role of a commodity; that may be ethereum's saving grace, since it has been marketed less as a currency and more as a smart contracting lubricant.

This applies to bitcoin too, but he doesn't seem to be aware of it. So when he later claims

> You cannot value Bitcoin, you can only price it: This follows from the acceptance that Bitcoin is a currency, not an asset or a commodity. Any one who claims to value Bitcoin either has a very different definition of value than I do or is just making up stuff as he or she goes along.

It's just not true. There is obviously some actual inherent value to being able to do escrow via multisig rather than via mutual complete trust in some third party. You can argue that the value is very low, but obviously there's some inherent value to the system.

What's weird about the actions of the self-driving vehicle in this case?

It detected that a truck was backing into it's path, and stopped in an attempt to prevent a collision. The truck driver didn't properly check his mirrors and continue backing up which resulted in the truck 'grazing' the front bumper of the car.

What exactly is a human supposed to do differently in that situation? Attempt to continue driving straight and potentially end up being t-boned by the truck instead?

Also, this vehicle looks super weird already. If the truck driver didn't see it, a 'placard' isn't going to make it more noticeable.

Fiat currencies work because as a whole, we agree on its value.

This is fuzzy thinking, as it doesn't even make sense to talk about the value of a currency - only it's price. Mixing up concepts like this is what makes a lot of bitcoin and related conversations very muddled.

When you start off your thought with a category error, as you have here, it's hard to get anywhere useful.
Bitcoin is a massive waste of electricity for no good reason other than indulge early adopters fantasy for unearned wealth.

All the fantasies and benefits it was originally promoted for have fallen by the wayside and only greed remains. It's an inefficient protocol and is now simply a store of speculated value and can't perform any other function by design.

The bitcoin ecosystem is eager to sell out to the very financial establishment they were ranting about throughout its history. News of any bank even thinking about crypto sees thousands of excitable news articles and soaring prices.
They even had trolls and shadow banning back then by the looks of things.
So if you're a US citizen or permanent resident or even just a tax resident (which includes working here on a temporary visa), the US taxes you on worldwide income. Any income from overseas needs to be reported (up to 3 times!) and taxed. With most countries you get credit for any taxes you paid in those countries. State taxes work the same in that you may have to file in more than one state and credit is given from taxes in one state to the others. This is actually all pretty sensible albeit tedious (particularly the part about reporting foreign assets and income).

Where it starts to go bonkers is for US citizens and PRs who live overseas. They still have to file taxes with the IRS for all worldwide income and report foreign assets and income as if they were present in the US. They get a certain amount of income (<$100k) each yeah exempted from US income taxes. Most countries do not do this.

My first problem is this: why exactly can't we treat companies the same way? I would be all for a 20% corporate tax rate if it meant a tax on worldwide income with credits for any taxes paid to foreign governments... exactly like individuals are treated. Why isn't this on the table? Is it that hard?

Second problem: in this world of multinationals and particularly when dealing with IP, companies seem to have free reign to book income in any country they like. Like any sales in the UK (and probably the EU as a whole) are reported to Irish subsidiaries.

To me this is fundamentally wrong. In other instances this is called transfer pricing and is illegal. For completeness, the classic case of transfer pricing is this:

Acme Inc buys a sofa from China for $200 in China and sells it in the US for $1000. That's $800 taxable profit right? Not so fast. Acme Inc instead forms a subsidiary in the Cayman Islands who buys that sofa from China for $200 and then sells it to the parent company for $990. Now only $10 is taxable in the US and $790 is taxed in the Cayman Islands at a zero or near-zero rate.

Now if that money is ever repatriated it's taxed. Thing is, it never is. Not until an ill-advised tax holiday and then the whole cycle repeats.

This brings me to the third problem: to get around the fact that all their money is offshore, companies borrow money in the US, which up until 1-2 years ago was at zero or near-zero levels. This debt covers their expenses and saves them from repatriating foreign profits and paying tax on them.

So why exactly don't we treat ever $1 borrow as repatriating $1 in foreign profits and tax it?

Now that would be true tax reform. Well, if we also got rid of the noticeably absent carried interest tax credit.

What a joke.
It's mostly a disambiguation thing, although it's definitely more popular in some circles than others. A similar term sometimes seen in more formal contexts is "US-American". "American" is sometimes construed to include all of North, Central, and South America, predominantly in Spanish and Portuguese languages (e.g. the Organization of American States / Organización de los Estados Americanos / Organización de los Estados Americanos), as opposed to modern English where the usual collective term is "the Americas".

Maybe you should consider adjusting your recommendation engine to default to keeping the price as close to possible as the original item.

Basing it off prior replacements (which were most likely not optimal the first time), sounds like the engine might be perpetuating mistakes.

I had another thought which might be even more terrifying. I couldn't find anything suggesting the fungus cuts off or disrupts the ant's actual nerve endings, and from video you can see towards the end that the ant moves in an unnatural, jerky way, not like a normal ant. This could be just because a fungus is bad at acting like an ant, but what if it's also because the ant is actively trying to fight it?!

I don't think this is especially likely, the fungus requires use of the ant's nervous system and sensory processing to figure out where a high up place is, so it definitely needs to have some significant control over the ant's brain, so it could suppress motor neuron function in the central nervous system. But still a very terrifying idea, to have some control over your muscles but the fungus is just overpowering you!
It'd be great to find out more of the cannabinoid profile of older cannabis. Recent times have shown such a focus on THC, and then finally an interest in CBD. I have a friend who finds CBD incredibly beneficial and calming of their symptoms, but really dislikes and cannot take THC as it aggrevates psychotic episodes for them.
