Wow.

You may have solved an issue with a new tunnel here in the Netherlands. The contractors and operators are puzzled why the accident rate of the new tunnel is so much higher than the old one, what with all the efficient and 'bright as day' white light. But if you're right and that adaptation happens then likely going into the tunnel your nightvision gets 'switched off' long before you still need at (at the tunnel entrance) because you're staring into the well lit tunnel, and at the end of the tunnel your eyes are likely still overloaded and are re-adapting to darkness.

The monchromatic lights they were using before probably did not cause any such adaptation and therefore did not mess up the nightvision of the drivers to the same extent.

They have tried to remedy the problem by dimming the lights overall and gradually upping the intensity as you get further into the tunnel but it is still a problem.

(sorry, only have a Dutch source for this: https://www.bnr.nl/nieuws/mobiliteit/10100389/rijkswaterstaa...)

So do I understand you right that would mean that during the night they should use monochromatic lights and during the day white?

Edit: I've sent an email to 'rijkswaterstaat', the federal infrastructure department of the government here with a link to this thread. Let's see if they reply.
The Germans switched off their nuclear power "to save the environment", which is why they have to burn coal, because the solar and wind aren't stable enough to supply consistent power. They also had to switch off some of their wind farms.
Maybe for heat, but not to generate electricity.

Yes, that stuck out to me as well. That was a poor way of conveying the point. The 34% of YC that do not have a .com will probably just buy it once they have the cash, regardless of whether or not they change the name.
Well, they might even be right. See, if the electorate believes it then likely so do the muggers (them being part of the electorate). And so the muggers will seek out the streets with the dimmer light.

Even if the science is lousy it might actually work out that way if there are streets with and streets without dimmed lights.

So the only way to control for this is to have the whole city dim the lights on some nights and not on others to compare when there was the most criminal activity.

Google works on tons of different products but their only real business is the ad business and it is hugely profitable and has been so for a very long time. I have no doubt about Google's ability to make large profits because they've demonstrated that they can do so. People keep saying Amazon can make similar profits whenever they want but I see zero proof that that is true.

AWS isn't a cash cow. It hasn't been proven to be a hugely profitable business yet. It makes a decent amount of money but at this point it's peanuts compared to the valuation. That said, I see a lot more long term potential in the AWS business than the ecommerce business but AWS has to grow by leaps and bounds to justify the current valuation.

I agree with everything you said.

On doing that in Idris (which is my dream language - the only reason I don't use it is its JS compiler is too slow), would it be possible to randomly generate elements of any data type, or would we have to write an `Arbitrary` instance for every type you want to test? I don't know/remember much about generics on Idris, would love to learn more.

(Seriously, though, why is the JS compiler still so slow? Again - I'm willing to put substantial money into funding a better one...)

BrickerBot Author Claims He Bricked Two Million Devices
Posted by another HN user: https://vimeo.com/214030931
Ok I'll bite. Let's back of the envelope the probability.

In the past 17 years I experienced 5 blackouts, so return period is about 1,241 days. Among the cities that were mentioned, San Francisco is the smallest, with population about 865,000. Let's look at all US cities with population above 500,000. There are 34 of those.

The probability of having simultaneous blackout in 3 of 34 cities during 1,241 days is 1-exp(-C(34,3)/1241^2)=0.4%, or about 2% for the same 17 year period.

The above calculation assumes independence, but in reality probability is much higher because independence assumption rarely holds in real life. For example, we already observed multiple large cities in the Northeast having simultaneous blackouts in 2003.

> "Singapore's way of doing things is that the government leads, then others follow," he told me. "This might be a problem - it is too centralised and so it may take too long for plans to trickle down.

Thus far, this economic model has well helped Singapore keep up with the times—though often not the first mover, Singapore is a consistent adopter of technologies just as they go mainstream. (c.f. NFC in public transport, sustainable architecture, smartphones, optical fibre)

But given the region's diverse business climates, I wonder if the more usual decentralized approach makes sense for most verticals for the region. Without significant expertise and infrastructure in localizing across the region, the SAM for any new product or service seems to be sufficiently small that technological improvements in most markets do not scale great enough to offset R&D costs and other fixed-cost risks for the potential margins to be enticing to investors.

Ontario has been coal-free for a few years:
http://www.ieso.ca/power-data/supply-overview/transmission-c...

There are many confounding factors (recession in 2008-2009) but generally, the number of days with smog advisories has been on the decline in Ontario as well:
http://airqualityontario.com/history/aqi_advisories_stats.ph...

Note that in general, across North America (not sure about the world at large) electricity consumption per capita has also been on the decline, to the extent that overall/absolute electricity consumption is down in large areas like Ontario[1]. I haven't done any research, but I surmise this is due to factors like more energy-efficient devices and time-of-day usage being pushed onto the retail user. (In additional to the aforementioned recession causing loss of manufacturing/factories)

Maybe for heat, but it's pretty unusual. I don't know of anyone who still uses coal for heat. It's extremely rare to see coal smoke coming out of chimneys and local delivery coal lorries are all but extinct now.

Plus it's pretty warm in the UK at the moment, most central heating is off and will be until Autumn.
what do you see? you can not open the video?
I think your interest makes sense considering the GGGGP post made claims of using IPFS in what seems like a usfeful setup w/o sharing the details.
Here in the middle of nowhere, rural England, I know quite a few people who still use coal for heat. Mainly it's people who live in houses that were built with coal fireplaces in each room. These are very shallow fireplaces where you couldn't burn wood or pellets, really designed only to hold coal. Some of these are surprisingly new, built as late as the 1950s. Even most of those properties have now been converted to gas or electric heat, but if gas wasn't available (or the owner wasn't willing to pay the installation cost), for many years, coal remained cheaper than electric heating, so some properties are left. The local department store sells two kind of coal at retail to cater to such customers, something I have never seen in any other country. But yes, I doubt anyone is using it this week, as it's not cold enough.
Rationally you are 100% on the money, but people are not always rational and I actually love it that they did this simply because they could.

What's the deal with natural gas? It doesn't seem "renewable"; isn't it extracted just like petrol? Is it just that it burns cleaner? Doesn't burning it still produce carbon dioxide?
Apple Autonomous Driving Training Program Confirms Self-Driving Software
There is a concept of self-deception. During a con, a successful conman does very little, they "just" have to prime the mark. After they bite, then they fool themselves so to speak.

Just because VC have money doesn't necessarily imply they are more rational or better thinking. Everyone involved here wanted this to be real and true. So while on paper due diligence was done, unconsciously nobody wanted to lift the curtain too much and peek what's behind.

This is also very common with software testing. Often when developers are testing their own software, they are not very good at discovering bugs and so they end up in production. This happens because even though rationally they want to ship a better product, irrationally it is hard to get into a mentality of proving that the product you just sweated months on is broken, or bug ridden or unstable and so on. So tests are written but they are written to show make them pass and show that stuff and unconsciously avoiding the trick or edge cases that would reveal brokenness.
Do you typically down-vote posts that don't happen to agree with your world view? I don't see how your points are any more well-founded than mine as they are all based on conjecture and not facts. Arguments like "Cloud's margin is very good" may make sense to you, but typically a well-reasoned argument states a thesis followed by evidence supporting it and I'm not seeing that.

You are also making all sorts of erroneous assumptions about what I said. I never said that I wasn't "impressed" by Amazon, in fact I think I actually said that what they've done is extraordinary. I also never said that online shopping, or Amazon for that matter, were "doomed."

And to your point about Wal-Mart being the "everything" store- name all the retailers on Earth that are larger than Wal-Mart. I'd be interested to hear what you came up with because last time I checked, there weren't any. Wal-Mart is the everything store, and has been for a long time. Why do you suppose that is? Could it be that most shoppers are price-conscious? If your argument is simply that ecommerce hasn't overtaken brick-and-mortar yet, fine, but then why does Wal-Mart absolutely dominate every other brick-and-mortar? It's because they've always relentlessly focused on figuring out ways to lower prices for their customers. In fact despite what a lot of people think, Wal-Mart has one of the most sophisticated distribution and inventory management systems ever created. It wasn't so long ago that Wal-Mart was being cast as evil because of their tactics bullying product manufacturers, but now people are writing their eulogy. Sorry, but the idea that mass-market customers are highly price-sensitive is well-founded and beyond dispute.

If you can't come up with a single potential threat to a business, you should probably take a step back and ask yourself if you're really looking at the situation objectively.

The strictness of the time limit works both ways. They'll be comparing you against other candidates who had the same amount of time. If nobody got a complete solution done, nobody is advantaged or disadvantaged.

The employer onboarding is designed to guide them towards the best practices I've discovered. 40 minute time limit and a clear expectation set in the challenge instructions that a "perfect" response is not possible in the time provided, so just do what you can and submit what you've got.

That avoids clustering responses near the top of the curve.

It also provides talking points for the interview. "So, given unlimited time and budget, where would you go from here to make this code production ready? If you needed to scale it to an OOM more throughout, where would you start optimising?" Etc.

Yes, it burns cleaner (a lot cleaner, coal plants need scrubbers on the stacks).

OMG, that first link is golden. It starts off by an email from DJB no less, which includes this snippet:

I should note that this plan, throwing away gcc and clang in favor of a
boring C compiler, isn't the only possible response to these types of
security holes. Here are several other responses that I've seen:

* Attack the messenger. "This code that you've written is undefined,
so you're not allowed to comment on compiler behavior!" The most
recent time I saw this, another language lawyer then jumped in to
argue that the code in question _wasn't_ undefined---as if this
side discussion had any relevance to the real issue.

And to top it off, below Kurt Roeckx explains to someone what part of the problem is:

The undefined behaviour of C is deliberate so that compilers can
make optimazations. They assume you write code that only has
defined meaning and generate code for that defined meaning. That
means for instance that if you add 2 signed integers they're going
to assume it doesn't overflow and then for instance make
assumptions based on that on wether other code ever going to be
executed or not.

Niiice. This exact scenario is what happened and it's given as an example of problematic optimization of undefined behavior by compilers. If I felt it was pointless to really expect any change before, I definitely do now.

I'm definitely favoriting your comment so I can find it easily later.
It's certainly cleaner as mentioned in the other comment.

Another factor is that natural gas turbines can be turned on and off more quickly than coal fired plants. This is because a gas turbine is literally burning the gas in the turbine, it's akin to a jet engine on an airplane you can throttle up and down. A coal fired power plant is really a boiler that creates steam, and then the steam is fed through a turbine. Heating up all the water to make steam actually takes a long time.

In an era of renewable energy sources (solar, wind) that fluctuate more unpredictably, having that "dispatchability" is really valuable.

http://www.nrel.gov/docs/fy12osti/55433.pdf
Natural gas also results in significantly less C02 released per unit of energy produced.

If my screen requires 250% scaling to be usable (which I am not making up - that is precisely the scaling it "recommends"), then lower resolution with pixels that are six times bigger is not a loss of quality. Large black squares composed of smaller black squares are not somehow ineffably superior to large unitary black squares.
c.f. my comment on the same quote, which contends that business and market-size reasons are a greater factor behind this development model, as opposed to ideological reasons.

A common refrain from those interested in starting-up in the region is the lack of investment money and investors' own refrains on just how fragmented the regional market is. Those trying to do or set-up business in Singapore often find that there is little to complain about with respect to regulations. Probably the greatest problem that involves the government as a party is finding a sufficiently sizable customer base without government backing, but this is explained by limited SAM.

It's nice to have the content and the comments handled by the same provider, so that they are available under the same circumstances.
Is the rate limit per API key, or per IP address sending the request? If it's counted by API key (which it sounds like it is), then the comments should stop working after 60 site visitors in an hour... But, if that's the case, wouldn't the influx of visitors from HN have already broken it?
