> What you would not do is to send a cryptic, pre-arranged signal

Where are you getting this from the article? How do you know it is "cryptic"? Of course it is pre-arranged.

Uber is known to run into problems with the government (which includes law enforcement). I'm not surprised there's a protocol for what a manager should do in this situation. If I was hired to work there my first question would be WTF do I do if the police show up?

I hate Uber as much as the next fickle HN commenter, but the idea of sending a text/paging a number doesn't feel that odd.
If I was designing a remote lockdown procedure to secure systems against a state, I would not design it such that local employees could unlock it without remote authorization, preferably from someone physically located in another legal jurisdiction.
And what if the delta between your upper and lower daily “trend lines” is measured in millions of requests per hour? Per second? We can leave off weekly/seasonal trends for now, and keep it nice and easy for you.

The utter lack of imagination that I see on HN when people are judging others’ technical decisions is kind of hilarious.
There are two problems at work. One is the poverty of the Central Valley. I strongly suspect this poverty is caused by more traditional problems, such as lack of economic opportunity, poor educational systems and exploitive corporations.

Then there is the "poverty" that is caused by urban planning issues in urban and coastal California. There are families making six figures who can qualify for affordable housing programs here. In no way should a family bringing in six figures be just barely scraping by, but due to the increasing rent burden that’s where many find themselves.

To all the commenters too busy being aghast at giving money to a government to read the article:

>Nigeria’s debt to Japan is the result of Overseas Development Assistance (ODA) provided by the Japanese government in 2014 for increased polio eradication. efforts.

>The country has made great strides in its efforts to eliminate the disease thanks to this funding.

>Nigeria did not record a wild case of polio from July 2014 to August 2016, when two cases were reported.

Presumably, the Gates Foundation wants to encourage state partnerships from nations like Japan in the service of eradicating solved diseases, regardless of a recipient nation's ability or willingness to settle incurred debts.

Money well spent.
Same thing, roughy.

Or rather: mindfulness was derived from Buddhist ideas.

Judges that sign off on search warrants will not be happy with this and will very much want to know what Uber is so concerned about hiding from proper law enforcement. In essence, judges that sign warrants will smell something very fishy here and they will not be happy. Uber is, of course, free to piss-off judges. However, they are not free from the consequences of pissed-off judges. Uber has also shown that they are just fine with handing employees over to the mercy of pissed-off judges, something at an individual without a stellar legal team is unlikely to view as a walk on the beach.
> Slightly off topic but articles like this make me weep as I look at my infrastructure and think about all the best practices that we by all means should be following, but aren't because of a senior engineer stuck in the 1990's and is seemingly not only paralyzed by analysis (and bikeshedding), but seems to subscribe to the notion as a way of living, and management who defers to him at every turn despite all evidence of how it holds us back (not to mention directly contributing to outages). I'd give my first born child for immutable servers.

I know that feel although in my case its non-technical management who just want things to be frozen in time.

Cest la vie at some companies unfortunately. Good luck with your escape plan. :)
Is this serious scientific research? Looks like a joke to me, or very bad journalism:

>During both periods, the USD-BTC exchange rate rose by an average of four percent on days when suspicious trades took place, compared to a slight decline on days without suspicious activity.

So price action happens based on trading activity, wow what a shocking conclusion. Here I was thinking prices went up and down randomly for no reason!

>The team found that many instances of price manipulation happened simply because the market was very thin for various cryptocurrencies including early Bitcoin.

Hmmm this seems to imply supply and demand also have some sort of effect on price movement. Another shocking discovery!

>As mainstream finance invests in cryptocurrency assets and as countries take steps toward legalizing bitcoin as a payment system (as Japan did in April 2017), it is important to understand how susceptible cryptocurrency markets are to manipulation.

And they came to this final fantastic conclusion about the present (2017/2018) based on alleged manipulation that happened 4 years ago on an exchange that no longer exists. Fascinating research indeed. /s
> supply creation is physically restrained by real world factors.

Yes, but regulatory factors usually dominate those in these high-cost markets. Like in Seattle's case, it's literally illegal to add to housing supply in most of the city; a majority of land is zoned exclusively for detached single-family homes. What new density there is comes in little strips, which means it tends to come in larger buildings, which have higher base costs to build. It's impossible to make "affordable housing" in a skyscraper.

If more cities allowed more "missing middle" type housing throughout their area, they could make a serious dent in housing prices. But, SFH areas are sacred cows in America (and I'm guessing much of Canada too).

>Having roommates in your 30s isn't that weird in LA, SF, and NYC.

Agreed, but I think it's weird that that isn't weird. Our parents' generation were able to buy a home, save for retirement, and raise a family on one person's income. Now we sign over half our monthly income to a landlord, and spend the rest on Avocado Toast.
The homelessness problem is one the most straight forward social problems that can be solved, unlike nebulous goals like decreasing crime, improving health, creating jobs, etc. Literally all it takes is building more places to live. The resources and land exist, the only thing standing in the way is political will.
The warrant is to "make the data available".

You can try saying "lol, the data is in Panama", but the judge is unlikely to care about that.
Indeed. I did not have a ~great~ manager until my 3rd or 4th job, and if I had known people like that existed before I certainly would not have stayed as long in some of the earlier jobs.
Yes, it's possible for the market to remain irrational for a while, but eventually prices have to come down if supply continues to outpace demand.

That said, according to a quick Google search, Sydney -- which is going to be the most similar of the cities you mentioned to American/Canadian ones, for obvious reasons -- apparently only has a 1.9% vacancy rate, which is very low.

I don't intend to discount your personal experiences at all, but in San Francisco's 2017 report [1] on homelessness, 69% of counted individuals reported that they were living in SF at the time they became homeless, and of those, 55% had lived in SF for 10 or more years.

Only 10% of total counted reported living outside of California when they became homeless. I can intuitively understand that weather may be a draw, but San Francisco's findings this year, as well as in 2015 don't appear to back that a majority of those experiencing homelessness in San Francisco are travelling there from outside the state.

Sounds like said "senior engineer" is an example of what I discussed in response to https://news.ycombinator.com/item?id=15975130.

Don't let it happen to you.
Congratulations, you just won an injunction from the court which requires you cease all business functions in the country until the data is provided.
I was once a certified lifeguard & first responder, and pulled a man from a river during a vacation. He had been underwater several minutes (the man couldn't swim), as he could not be seen--the water was murky & visibility was < 12 inches. He was not lifeless, as he vomited after rescue, but we was not resuscitated and died on the scene.

It's been about 12 years now, I think.

I made some mistakes which I think could have been avoided. Not the mistake of standing by, but I didn't keep my training at the front of my brain. Namely, I did not ensure 911 was called before we found the body, and I did not spend a few seconds trying to recruit more people to look for the body. Both of those may have saved his life, it's hard to say.

I haven't found a silver lining, and I don't expect to. I simply hope that I can perform better in the event that such a thing happens again.
Appears that this article is not true according to another article titled

That's interesting. Why would they buy it for more than $2? Is it because the exchange is selling for more or just problems with international currency.
I was a little disappointed by the lack of explanation on how light refracts. It references Snell's law and mentions how light travels slower in water, but it did not go into how it's an effect of parts of the wavefront changing velocity at slightly different times as a result of the light entering the medium at an angle (or at least that being a simple way of understanding refraction.)

However, it was cool to see them reference "Do dogs know calculus?" I actually saw Pennings give a presentation on it in high school because my calc teacher was one of his students. He started out the talk by telling us that his dog knew calculus. He then proceeded to ask his dog the derivative of x^3. The dog did nothing, and he told us that dogs don't know calculus.

>For example: if I (the police) have a French warrant and serve it on the Paris offices of Uber, but Uber has a pager service that performs whole disk encryption and sends the keys to a server in Panama, where does that leave me?

Some say some books need to be chewed and digested, but that it is worth the effort. Well, I've been chewing this from time to time since his 2011 Turing prize; and I have yet to be able to build an understanding around it. Understanding Michael StoneBreaker's was much easier. Build great databases. Several times. Get prizes.

It feels like this causality formulation begs for modelling, and for a program to be able to execute and test its own do-calculus actions; to provide the world with a compelling 'Hello World'. Maybe emit some counterfactuals too.

Reinforcement Learning seems to yield way better results at exploring the world; at producing actions that help model and test (and then influence) the world.

Why is not more used? What's the story around it?
If you really meant for the 10x to only be an example, you should have clearly stated that.
As a Californian I don't agree with the sentiment of this analysis. Sure, certain segments of the population here are doing well -- particularly, the well-off and those from out-of-state -- but if you were born and raised an average life here any time in the past 35 years, particularly on the coast, then your life is particularly tough in some areas: $1500 rents for a 1BR apartment, super-low wages, apathetic middle class, increasing traffic, now we have a homeless problem....

More succinctly I disagree with the authors' assertion that CA is doing fine "if you take out housing prices"
I'm I the only one who thinks that Japan kinda looks bad here?

I mean, Bill's foundation is already dedicating $3B a year on development assistance, couldn't Japan just say to Nigeria: "You don't have to pay us back. Consider it a donation". How could they reasonably expect Nigeria to pay them back $76M?
How would they prove who did it? It could be done with an encrypted message.
> Yes, emulators are legal. But we all know that the overwhelming use of them is in illegal situations.

I use emulators to play games that I rip myself, so it's not because something can be used in an illegal way that it should be forbidden. It's like saying "oh, pot could be used legally but most of its use is illegal" - if people use it this way and it's against the Law maybe there's a problem with the Law in the first place.
You appear to be correct on your suspicion.

You should review the difference between CapEx and OpEx, and specifically focus on why companies might prefer to pay “5-6x the total cost” when that cost comes in the form of OpEx.

You may still disagree in the end, but you should come to the conclusion that it is not categorically stupid for some companies to choose to pay much more over time so that they can pay a lot less right now.
Thanks. So once he lost his suit on those grounds, he should immediately file a lawsuit (possibly class-action) for fraud, false advertising and deceiving current and potential clients of Pepsi, since Pepsi lawyers admitted clearly that it is even impossible to deliver winning award to the winner, something they failed to reveal in the fine print. Unless of course Pepsi can prove that this commercial did not bring them any changes in profit.
It is amazing to see how Bill Gates immersed himself in his nonprofit work. I hope he stays rich so he can do more of these.
I am in California, so perhaps this is just confirmation of your guess that it's a California-ism, but I certainly use "Hey $name" and even less formal things (if that's possible) to address my manager (and even my CEO). I did the same when working in upstate NY, though (~15 years ago), and my impression is that such informality isn't particularly unique.

I've actually never worked anywhere such formality was expected, and suggesting something like that would probably get you some weird looks. I wonder if it's an industry thing? Perhaps some industries tend to enforce politeness/formality between rungs in the career ladder more than others?
Ah, well, that pretty much confirms it :)
I think the parent's point is that if there is a warrant to collect information, the machines can be seized and the company compelled to comply. This move prevents overreach in the moment.
Correct me here if I'm wrong but the linked article actually uses the example of a new CSS property as an instance of something that would _not_ require a security context.
Increasing block size is not a sustainable solution for scaling transactions. Transaction fees are too high and BTC should move to 2MB as a short-term fix but the long-term fix is off-chain solutions like Lightning.
In the U.S., people have the right to remain silent during interrogations, so there's no problem with a lawyer advising a client to exercise that legal right. A lawyer can get in trouble (e.g., get disbarred) if they advise a client to break the law, e.g., by committing perjury or destroying evidence.

> Does this change if the person is suspected of having pot or of killing children?

The U.S. legal system has a presumption of innocence, so merely being suspected of committing a crime shouldn't affect the legal rights you're entitled to. (Many innocent people become suspects in police investigations.)
I did not say it accounts for a majority of homeless Californians. If it accounts for even 5 percent, that would be a lot of people. Your figure of 10 percent coming from out of state actually supports my assertion that homeless people actually travel to California while homeless. The only thing missing is data as to why they made that decision.
Well looking at this it appears it was a very misleading op ed piece.

Making claims public can sometimes increase their credibility, because when you've told everyone, everyone will know if you break your word.

Of course, it's debatable how much a CEO cares about being seen to break their word; it's not like Elon Musk suffers any negative consequences for announcing over-ambitious delivery dates. And it's hard to believe the embarrassment of ending production of your flagship plane would be smaller than the embarrassment of not doing that when you said you would.

The article isn't clear, but I'd guess from the small outbreak in 2016 after being Polio-free in 2014/15 that the concern is that polio still isn't completely eliminated in Nigeria. Presumably it will need ongoing monitoring for several more years to ensure it is completely gone. Having to pay back the debt could jeopardise that ongong effort. In which case, this seems a good investment.
Bitcoin
Hi all,
Living in Australia and I tried to withdraw 10k AUD from coinbase.com.au into my Commonwealth Savings account. The transaction was cancelled by the CBA and they sent me an email about it. I will soon be releasing the email and transaction details on Reddit, but by the looks of it CBA will not allow me to convert my bitcoin back to Fiat.
I am looking for a new bank, hopefully ANZ will work.
Good luck to all wanting to get Bitcoin back to Fiat if using the CBA.
Wikipedia gives 2.231 million barrels exported per day for Nigeria in 2013. At $50 per barrel this amounts 40 billion Dollar per year. I have no idea what the profit margins are but at 10 % this yields only 4 billion Dollar in profits per year which seems rather little to me, especially given that it is the 6th largest oil exporter. So 76 million Dollar would be 1.9 % of the annual profits from oil exports, not much but also not negligible. But I think I must have committed an error somewhere, those 4 billion Dollar just look too tiny to me.

Yeah, and AWS has a free tier. $0/month is better than $100/month, right?
To be fair: these are three very different kinds of store, designed to meet the needs of very different workloads, and trying to solve very different problem sets.
I worked at Be for almost a year, and used BeOS for a couple of years before that. I am not an expert, but I can mention a couple of things.

The biggest one was: freedom from backward compatibility. You can't comprehend how much cruft you are drowning in, in your typical OS, until you are free from it. Coming to BeOS from Windows, as I did, it felt like 2,000 pounds was lifted off my shoulders.

BeOS was free to fully embrace some modern technologies that had been bolted on to older operating systems as an afterthought. The biggest one was multi-threading. Having spent years on earlier operating systems, I can say that all of them have a stunted idea of multi-threading, compared to BeOS. Typically, you are forced to run your user interface in your main thread, and you have to run background tasks in background threads, and invent ways to communicate between the two.

Contrast BeOS: every single window runs in its own thread. Think about that for a minute: If you write a BeOS app that has two or more windows, surprise, your app is multi-threaded. Whether you like it or not! A lot of programmers, coming from older operating systems, very much did not like it. Personally, I came to embrace this as BeOS' greatest strength. Communicating between windows was pretty natural: just drop events into each other's event queues, which were of course thread-safe.

Unfortunately, the early architects of the system made their own set of poor decisions that led to a new round of cruft. The worst of these was tying themselves to the ABI of a particular C++ compiler. GCC version 2.9x, I think. In the last year of Be's existence, we were really feeling the pain of this. The compiler we were shackled to was many years out of date. If we switched to a modern compiler, it would have a different ABI, and all older software that couldn't be recompiled would have been instantly broken. Nonetheless, there was a vocal minority of engineers inside Be who argued for doing just that. We weren't focused on external users at that point, just internet appliances, so we could have gotten away with it. But we were all BeOS users ourselves, so we would have lost a lot of useful apps that way.
Had anyone had resounding success with serverless technologies?

The CLI tools work, but they're frequently more of an annoyance then running a single process app. The logical layout and composition falls entirely on the team. Composing related functions seems to be more troublesome than it's worth.

Is Go on lambdas exciting because people use Go for cross cutting devops operations? Is there demand for writing serverless Go?

I see containers and the single process model as much easier to test, lay out and run. Honestly, I probably just do "get" serverless. What am I missing?
I know I do. If you applied and you can't even keep up a decent LinkedIn, why should I interview you? Or better yet, trust you?
