See footnote [2], and the problem is that (as with driving styles) there may turn out to be a correlation between how often you think about murder and how often you do it, which can be used to calibrate insurance-risk premiums.

Sure, not every thought about murder leads to murder, and not every red light you run leads to an accident. But people that run more red lights have more accidents, and people who think about bad things more (let's posit) will do more bad things.

"Oh, you only think about murder 3 times a week? Discount!"

There is another way to get the hit rate higher, just like we got better at stuff we couldn't so in the past. It's called SELECTION. That's why all our industrial processes today are better than 100 years ago. They aren't "safer", or performing worse, they perform better than EVER because we have figured out what works and standardized it.

In accelerators, that means having more consistency in what factors work, and more selectiveness. Take things that repeatably work and use that.

In my opinion, companies like Google build one hit after another, internally, by re-using their internal platform and users and virality. There are failures but not as much as with startups. But it all benefits from internal resources, server farms, infrastructure, user base etc.

If you are outside such a company, use an open source platform that worked for others. We are working on such a platform and will probably take partners in a couple years, to build apps for our several million users, and provide them with all the infrastructure to try things out and take a % if it works out.
Actually, the fact that government-regulated private utilities are very reliable and low risk generators of investment returns (people still consume energy during a recession) is the reason they are a cornerstone of many retirement investment funds.

Locally operated municipal utilities, however, are less likely to be turning a profit, at least not one that benefits shareholders.

How? I don't see a 'grams of free glutamate' label on food. I can't even find sources that tell me the average amount of free glutamates in foods where MSG is typically added.
It's both :)
> If the market is gone, the land on which it was located would be very valuable indeed. Proximity to upscale district and plenty of waterfront property. It's really not a place where a sprawling fish market should be.

Land valuation is based off of the revenue the land generates, plain and simple. The 'value of a land' is thus an index of the real estate market, and does not involve any positive (or negative) externalities involved in considering the use of land, density of land, mix of programs of land, etc.

At times, it may be important to support and privilege land uses that don't maximally contribute to revenue but contribute to other land that contribute to revenue.

To use the metaphor of food consumption, it would be like assuming that the value of food lies in the energy that it provides to the body, so drinking water is pointless because water has zero calories. Indeed, like a body, cities are metabolic entities.

The notion that urban planning decisions need to be based off of (short-term) market-based valuation misses the potential to invest in long-term positive externalities. Infrastructure is not something that can be effectively funded by a market, because markets lack a proper valuation criterion.

So - the land on which Tsukiji is located is very valuable inded. And Toyosu, where it's going, is actually pretty close. But "moving the fish market will create valuable land for Ginza's overpriced highrise offices" is a short-term strategy, plain and simple; in this case, perhaps it's one that makes sense.
The point of the analogy is that it is very easy to prescribe behavior that is guaranteed to work if followed 100% to the letter, but fails catastrophically if there is even 1 mistake. There are two responses to this - you can either design systems that are easier to follow & fail less catastrophically in the real world (don't use C for new code if you don't need it; teach people about safe sex practices), OR you can double down on the sermonizing about how if people had just been smarter / had more willpower, they wouldn't be in this bad situation.
In many cases, sure, however there are definitely cases where microcontrollers still make sense, i.e. real-time control, low power applications.

I work in embedded systems, and a lot of the reason you would choose a microcontroller is all of the peripherals that are also part of the chip. For example, if you are doing a project where you need to control motors, you can get a micro with a lot of built in high resolution timers , built in hardware for motor commutation, decoding of encoder signals, high speed analog inputs for feedback, etc. You would also typically AVOID having a linux environment, and opt for either a hand coded loop, or an RTOS which gives predictable, deterministic performance.

In my particular industry (robotics), we definitely do like to use a more powerful computer with linux or some other high level OS on it for a lot of the high level intelligence, so a lot of what you end up seeing is almost a 'distributed system on a board', where you have a more powerful processor providing the intelligence, which then issues commands to the less powerful microcontrollers which do things like control motor torque, sample sensors, etc...

This doesn't even get into things like power consumption...simply put you can have microcontroller based systems run for months on a single coin cell battery, which is going to be a hell of a lot harder to pull off on a RasPi / linux based system.

All that said, for a lot of projects where you just want to monitor a few simple sensors, or do a basic home automation type of project, a RasPi can be a great choice! (Even if my inner engineer is screaming 'your over complicating it!') But there is definitely still a huge need and use for micro-controllers as well.

Hope that helps answer your question!
> But does the fact that I know the limits of my car's abilities make me a more dangerous driver?

Perhaps. Devices like this might tell them if people that occasionally drive hard are more likely file a claim.

I'm guessing they will track everything they can reasonably track and the set of things they can track will increase over time.
12 Ways He Says “I Love You” Without Saying a Word
"It's not that simple. A system that is not grid connected will need a lot more than just a battery to make it as reliable as a grid connection. Those 'few short years' are more likely a couple of decades, in other words well over the horizon for the people that are currently trying to squeeze the most profit from those utilities."

How are panels + battery not as reliable ? I think you mean they don't last as long, right ? As in, theoretically you could use up the battery before the sun rises again so it's not as nice as the utility ...

As far as I can tell, panels + battery (properly sized, and admittedly expensive) are all you need. You can just cancel your electric service at that point.
There is even a more general technique -- do the unexpected, to break the expected social protocol.

In situations like this, if there is an aggressor (say the customer in this case) they expect a certain outcome. They envision how the interaction will go. "I'll be demanding. Employee will get upset, maybe a bit snippy. I'll yell at them and show them who's boss. Maybe even complain to the manager." But in turn they see a smile, complements ("Oh, what a beautiful Porsche you have!") and willingness to help. They are angry inside but it is hard to manifest it without appearing completely crazy.

I've heard of other stuff like this:

* In a dangerous part of town and see a bunch of shady people eye you up -- act crazy, mutter to yourself and maybe flail your arms. Friend liked to do this in a bad part of Chicago.

* Someone wants to pick an argument and is just contrarian no matter what you say. At first argue a bit, then immediately switch sides and argue against your old position (basically on their side). Also to make it fun, be kind of aggressive and angry at your old position just like they were.

* An aggressive panhandler is verbally harassing you asking for money. "No thanks, I'm good. Talk to you on Wednesday". Say it, as matter of fact as possible. Their mind will stop for a bit trying to process that, and it gives you enough time to walk away far enough.

It's really crazy how common MSG is, and as a result it can be very difficult to diagnose an allergy. A friend of mine has a severe reaction to MSG (diarrhea, skin lesions, etc.), and it took years of misery before he figured out the cause.

It's found naturally in many foods you wouldn't expect (pears, cucumbers, tomatoes), and other times companies add it to unexpected items (Dole sprays it on bananas).
Ah, you are the maker of the graphic.
Well, I vaguely remember the graphic I saw.

But as a feedback

- What are the two extremes? I don't know the end points in your graphic.

- You graphic does not show how the center shifted from the East to the west after the industrial revolution. Because from 1500 to 2010 you actually have either hard data or past estimates.

- I would have put the distance of the dots (years) and a color legend in the picture.

- I am to stupid to understand what the different sized arrows mean in the graphic. What information do they provide?

You're right, using uintptr_t for pointer arithmetic is a bad idea.

I've worked on systems (Cray vector machines) where converting a pointer to an integer type, performing arithmetic on the integer, and converting back to a pointer could yield meaningless results. (Hardware addresses were 64-bit addresses of 64-bit words; byte pointers were implemented by storing a 3-bit offset in the high-order bits of the pointer.)

Pointer arithmetic works. It causes undefined behavior if it goes outside the address range of the enclosing object, but in those cases converting to uintptr_t and performing arithmetic will give you garbage results anyway.
Thanks for that clarification. The few times I have had attacks were either after Asian restaurants, that Zatarain's rice (MSG clearly indicated in the ingredients, I checked after my attack started) and my first time: Quiznos.

I had so few attacks, that I forget about my intolerance. Not sure if I had headaches, because I was so focused on my pseudo heart attack! I spent 7 weeks in Vietnam and I saw MSG everywhere. Never had an attack.

I constantly eat parmesan, mushrooms, or tomatoes (rarely blue cheese). I have always been a "jumpy" person, perhaps these foods always have affected me, just slightly. Perhaps it is the time to be formally tested. Thanks again.
I'm not - I plan on turning this into a business, and will be including yoga studios as my next iteration.

Yep, it would penalize those who have high risk markers but are nonetheless actually safer. Seems to be the same problem as charging more to an individual 16 year old who is actually a safe driver.

Unless they have to, power companies are not going to buy your excess solar power from you at all. So yes, regulation is required to prevent monopoly (or oligopoly) providers from abusing their position.
I strongly disagree.

You can keep a low hit-rate and focus on giant returns by playing the lottery, but fortunes are built on compound interest and diversified portfolios.

Reducing the number of failures does not mean getting rid of the big winners. It could mean focusing on large existing industries over speculative, pie-in-the-sky trends.

Think about ZenPayroll (disclaimer: early employee there, biased.) Product-focused payroll is not sexy, but the impact is massive and a tremendous business opportunity. We're now building software for local governments. Not sexy, huge market, huge impact on humans, clear path to single, double, and home-run.

My biggest frustration with looking for founding teams chasing these speculative bets is the sheer waste of human talent. I don't want to see another all-star team waste their time on bitcoin and food-delivery.

There are real, serious problems with the same upside but whose "failure" scenario may be a $25m business.
It's good, but its no House Of Cards.
And it's wrong for yet another reason. You can convert a pointer to uintprt_t, but arithmetic on the result isn't necessarily meaningful.
Good idea! That's exactly the kind of feedback we need, thanks. We're working hard on new SDKs. iOS will be first, node.js right after it. Should be both in Q1.

I'm surprised by parent and gp. Mexico City is beautiful and interesting and full of things to do, but driving a car there is a nightmare. My first fifteen minutes behind the wheel there changed my view of traffic and laws forever.

I suggest visiting without a car. If you need one to get to places outside the city, rent only when you're leaving and ask for exact advice about the easiest way out of town.

Android the OS isn't where the value lies. It is the Android ecosystem - the applications, drivers, and hardware.

Google has essentially taken over the ecosystem via their Google Play API. I know this first hand as my beloved Blackberry OS 10 was able to run Android apps. Now this is almost impossible as the majority of apps created in the last few years have hooks into Google's APIs and absolutely won't work without all of Google's hooks into your privacy.

I don't imagine roms that avoid GApps will be a viable alternative in a year or two either.

Microsoft has been trying to develop an ability to run Android apps on their phones, and it looks like they're giving up too due to Google's lock on the APIs.

I'm shocked that this ended up on a commercial flight. After reading Command and Control though, I'm sure this stuff happened all the time in the past and it was just quietly swept under the rug.
http://research.google.com/pubs/archive/34913.pdf section 4 discusses performance: "The worst case performance overhead is [the SPEC2000 benchmark named] crafty at about 12%, with other benchmarks averaging about 5% overall." For some applications, there is no slowdown or even a minor speedup because of weird caching behavior and alignment.

I haven't seen this used for a general-purpose OS distro (I suppose you'd use it for running a VM-like thing as an unprivileged user, without access to any hardware features) but I agree it would be cool.

>farm subsidies

The phrase 'Farm subsidies' doesn't quite do justice to what was put into place. The phrase sounds like just giving farmers money to grow stuff, which people might think is inefficient but probably not that big of a deal in the grand scheme of things. After all, these sorts of subsidies should increase supply and lower prices.

The reality is there's a tangled web of price controls, subsidies, import quotas, government purchases, etc. that in many cases have resulted in higher food prices, not lower food prices as simple subsidies might imply.

Take sugar, for instance. We have import quotas and tariffs on sugar resulting in higher sugar prices in the US than in the rest of the world despite having sugar growing regions in Mexico or the Caribbean on our doorstep. This is one of the reasons that we use high fructose corn syrup in everything instead of sugar. If we didn't have these laws, we'd have cheaper, more abundant sugar and probably less HFCS infused food.
Sure, that's what we used. It ends up being noticeably more costly than natural gas so I think about them as different things (the price is also less stable, this hit Minnesota hard a couple years ago).

That's why Effective Altruism movement settled on the 10% of income as a default "good enough" contribution. As Scott Alexander explained in [0],

"It’s ten percent because that is the standard decreed by Giving What We Can and the effective altruist community. Why should we believe their standard? I think we should believe it because if we reject it in favor of “No, you are a bad person unless you give all of it,” then everyone will just sit around feeling very guilty and doing nothing. But if we very clearly say “You have discharged your moral duty if you give ten percent or more,” then many people will give ten percent or more. The most important thing is having a Schelling point, and ten percent is nice, round, divinely ordained, and – crucially – the Schelling point upon which we have already settled. It is an active Schelling point."

It's still better to get a suboptimal outcome than to not get any outcome at all.

Silicon Valley is dominated by a few big tech companies that hire tens of thousands of employees they don't really need, in large part just to keep them out of the hands of a competitor.

With Alphabet, Inc., Google is in the process of decentralizing itself into a version of YC. They're essentially VCs now. At some point someone (maybe Alphabet) is going copy the YC model effectively and scale it up to tens of thousands of startups. It's just too damn profitable and efficient to not become the standard way Silicon Valley works.

It would be neat if in a few years all the big tech companies are basically YC alternatives and most people work for a small startup that actually makes something.
Taking fewer risks and only investing in "sure things" is in neither our interests nor the founders. The "safe" option is to not fund them at all, like a bank or other conservative organization would.
Your response to this article is a million times more clear and informative than the article itself. Cunningham's Law in action.
Sorry if I think you're overstating your achievements.

- Was your code unit-tested?

- Did you use the 'strn' functions? (strncpy, instead of strcpy for example)

- Did your code run under Valgrind? (was there valgrind at that time? I'm not sure)

- Was it tested for memory leaks?

- Was there input fuzzying tests?

I agree that there are ways of writing great C code (like nginx, the linux and BSD kernels, etc)

But from a certain point on you're just wasting developer time when you would have a better solution in Java/Python/Ruby, etc with much less developer time and much less chance of bugs and security issues.
This is a weird argument as a benefit to hunter gatherers. The benefits you're discussing are only tied to a hunter-gatherer lifestyle because of low population density. They would have the same issues if they were at the population density we are now...but they couldn't be, because the earth couldn't sustain them.

It's definitely not an argument in terms of looking to hunter gatherers for diet or fitness advice, though :)

That's a pretty big straw man. Even at 8mph if a toddler wanders into the road you are going to have a pretty big jolt from slamming on the brakes. If you've never been driving at or below posted and safe speeds in a neighborhood and still had to slam on the brakes because a child's ball bounces into the street (invariably followed by the child), you are quite lucky.

Even with 100 feet to spare, you still slam on the brakes because when a kid wanders into the road, that's what is safest.
