Right we should trust them because the police never abuse any tool or weapon they are given to the ultimate extreme.

pepper spray, washing people entirely in it

tear gas at rallies even though banned for use in war

stun guns used repeatedly on unarmed people not even standing or fleeing

shooting unarmed people for non-violent crimes for non-compliance during arrest

tracking people without warrants via stingray devices

tracking people via their electronic toll passes from streetlights

harassing anyone trying to file police abuse reports to the point of arresting or stalking them

seizing massive amounts of money and property under civil forfeiture laws without any proof of criminal activity

using fees upon fees to seize property and jail people for not paying the fees

certainly they would never abuse this and radiate people standing around or at intercetions, never, trust them

I still think we should give Tesla the benefit of the doubt. This article feels like a hit piece, again. At the very least, it's a media organization gleefully taking a hit at an innovative company. I support Tesla less because it has great cars, but because it's really trying to build a better car.

I don't think the article is trying to imply that we should be making stuff just for the sake of making stuff, or creating jobs just for the sake of creating jobs. It's just giving an explanation for why many new industries don't show up in productivity measurements.

If car sharing did take off in a big way, then it will redistribute value. Presumably fewer cars will be sold, so car manufacturers will be worse off. The people sharing cars might be better off (they would earn money through sharing, but note that they are sacrificing several things for the added income), and the companies running the sharing business definitely become wealthier.

> I would be tempted to think the fact drugs are rare and difficult to obtain the first times decrease the odds of somebody becoming an addict. Pure speculation but there is some logic still. Say one night I'm crazy, I'm not going to find cocaine right away become hey, tonight is the night. I understand that it's not a proof that it's effective. Just that it might be.

Your logic seems fine to me, but it's based on an assumption that it is hard for people to find drugs for the first time. You're probably not frequently presented with opportunities to do heroin, but you're also probably not the kind of person who would do heroin even if you had the opportunity. Drug dealers aren't going to approach you to sell you heroin because the risk/reward ratio is too high. The same is not true of teens and people in their 20s in poor neighborhoods.

> Doctors prescribe morphine, most likely when not using it is worse than using it, which doesn't mean the risk are low.

True.
I don't know purescript or elm, so I can't speak for their qualities. But, I also don't know half the languages cited nearby either (livescript, clojurescript). How can I pick and learn "the right one"? They all seem the same to me, and I think that's the problem.

Valid feedback pekk. One of the reasons we consulted with people who have run growth at a number of companies is because they could give the inside story; company X did Y because their metrics told them to.

That said, a huge caveat is that this all depends on your audience and what they're going to respond to.

I would posit that startups are more apt (than a larger company) to experiment with marketing, which is valuable.

> Existential operator accessor (?.) is a leaky abstraction for null

I found this out the hard way when using it in groovy a while back. The Options abstraction you describe is better, or the one in Java 8, which Groovy still hasn't brought into its syntax. Groovy's creator James Strachan talked a lot about how he designed Groovy to avoid the "leaky abstractions" in Java.

> Sharing is a process that optimizes usage of available resources. Why should we make more cars than we need?

Isn't it weird how we spend so much time talking about conservation of resources and then an article like this will make the same people say, "Sharing leads to no production!". Like you mentioned, this is simply a matter of humans getting better at making things and using the things we make. We'll find new things to make.

Production != progress. Increases in wealth == progress.

My dog had this procedure done when he was a puppy which saved his life. The standard procedure is to crack open the dog's chest and tie this pathway off. This is the old way of doing it; we don't do this to humans anymore as there are a lot of risks involved and it takes a long time to heal. The much more expensive but safe procedure is to go through the femoral artery. He now has a platinum coil in his heart and no longer has a femoral pulse because they tie it off.

List of RubyGems with memory leaks
Tesla is showing what a car can be - Excellent UX, a nontraditional but really nice drivetrain, a good UI for the secondary systems with frequent software upgrades, etc.

It's not hard to see the trend - it's been coming for the last 15 years at least. All drivetrains will be electric, and connected to a battery and optionally a range extender of some sort. The control panel will be all big screens and apps.

Meanwhile, the existing manufacturer are perfecting the ultimate gearbox. They are in at least partial denial now, but they will soon need to dismantle those investments and some others to stay alive. Ex, Audi that has kept a really complicated gearbox instead of doing what Mitsubishi did, using a fixed gear system and a serial hybrid approach.

(To be fair, they have nothing to gain from these changes, they just want to stay slightly better than the rest.)

The bet against them is that some of them will not be able to reinvent themselves and then wither out into obsolescence.

I think that this risk might not be fully included in the price right now.

> For much of the code, lengths were converted from ints to size_ts and functions that returned one, zero or minus one were converted to just returning one or zero.

Doesn't google's C code style require using signed ints for lengths?

https://google-styleguide.googlecode.com/svn/trunk/cppguide....

As it should - it's inappropriate to use unsigned types for length because the overflow and underflow behaviors are defined, since they're not defined to what you want. When you have ubsan around, adding defined behavior you don't need just adds places to hide bugs.
I could get over the parentheses but CAR and CDR instead of HEAD / TAIL or FIRST / REST annoy the crap out of me.
"Chaining or nesting a series of function calls, depending on the language, can be more readable still than the variables approach and at the same time more concise".

Couldnt agree more, variables are just clutter you have to keep mental track of, and working with series of transformations is much easier (for me at least) to process. I would be interested to know if its like this for all developers, perhaps not, since I know some that are also opposed to recursion.

but for me this:

sum([]) = 0.
sum([H|T]) = H + sum(T).

is much easier to understand than:

function sum(ary) {
var i = ary.length,
res;
while(--i) {
res += ary[i];
}
return res;
}
It also solves only half the "problem", since each decade still has its own name.
Yes, the option of having your autonomous vehicle go off and work as an uber driver while you're at work is a point in favor of Uber continuing as a broker, and keeping out of the fleet management/capital investment business.

Which makes it confusing that Uber has made noises about wanting to buy self-driving Teslas in the past...
They do have a significant head-start over most competitors.

When companies like Porsche talk about launching their 'Tesla killer' - it's set for years into the future.

It's definitely not rational to think Tesla will dominate, as no company actually dominates the auto industry. Toyota arguably comes closest and they don't dominate, they have a modest market share compared to what traditionally dominate companies have.

Can they one day do $20 billion in sales and ~$1.5 billion in profit? Probably. That would justify their present valuation (they will very likely carry a higher valuation than most car companies, for the same reason companies like Google carry a higher valuation than IBM). The real problem for investors, is it may take eight to ten years to justify their present valuation.
I've done it a few times myself as well. Do you find that your mind is much more single threaded than you would have expected beforehand?
Nexus 5X and Nexus 6P review

Which business model self-driving taxi operators go by is pretty irrelevant; the free market will settle on the best way. The productivity increases will benefits the entire society should be the most important part of any analysis.

Unconscious bias: How Twitter found the best ‘man’ for the job
I'm just curious about how this works with some things that seem to add complexity (I haven't worked in this area at all):

- Different names for things in different parts of the address because of different languages? (What if two different parts are in different language, e.g. giving a Belgian city name in Flemish but the street name in French? Giving a Swiss address with a street name in French, city name in German, and canton name in French+? Giving a Russian address with the street name in Russian but the city and oblast name in English, possibly using different scripts?)

- Landmarks and points of interest, maybe with separate colloquial and official names? (Tower of St. Vincent? Torre de São Vincente? Torre de Belém? Tower of Belém? Tower of Belem?)

- How do you search if an address component is omitted (like leaving out a city in a U.S. address but including a state or a postal code)?

- How do you handle free-form text searches that might omit address delimiters, or include postal codes in a locally nonstandard order, or omit or include official postal designators for the components of the address (for example, Brazilian addresses might include the word "CEP" before the postal code but could be given without explicitly mentioning that the postal code is a postal code)?

Is there a good book or web site or FAQ about geographic name matching that I could look at to get a sense of what standard answers to these sorts of questions are?

+ In Switzerland, the same city could theoretically be referred to as "Fribourg, [Staat ]Freiburg" or "Freiburg, [État de ]Fribourg". Well, of course a human user might always search using any combination of languages with which they're familiar, or even ones they're not familiar with that they just copied and pasted from somewhere.

Some of those are irrelevant.

For example, "National Standards for Education are not really followed". The US uses a federal system where the state sets the standards, not the nation. While the federal government does use its power of the purse to get the states to follow, let's say, national recommendations, it's still state standards.

And "Education could be the answer to child marriages" has a mistake in logic. The argument is "The girls who complete their education are likely to enter into marriage as adults." However, the UNFPA article says it's the other way - those who get married as a child are more likely to stop their education. It doesn't say that keeping them in school will make childhood marriage less likely.

"Children with learning disabilities are bullied in school" is without context. If 45% of the parents of learning disabled children report bullying, and 55% of the other parents report bullying, then both are horrible, but being disabled wouldn't be the reason for being bullied.

Moreover, some of the facts concern the entire world's population, while others, like this, only concern the US. It's a bit improper to pick and chose that way.

> another great lesson of that book though which is short code (by lines) > longer code simply because it's easier to consume in a single glance.

I hate this lesson. And it's not because short code is a bad thing...when you find code that's well structured and broken down such that no method/function needs to be long, it's a joy to read. The problem comes when people learn the rule without learning the why behind it. And that leads to one logical function/method that's huge and has now been broken down into many nested methods/functions simply to satisfy the "none are long" requirement. Now, as a reader, I've still got to keep the entire context of the method/function in my head, but I now have to jump all over the code to find out what the single, large method actually does. I'd rather have a single, 200-line code block to look at than this sort of jumble.

What developers need to learn is that short methods/functions are a consequence of good techniques, not a technique in and of themselves and that long methods/functions are not bad in and of themselves, but they indicate that it's very likely that the developer hasn't put the proper thought into separating concerns and ensuring that each unit of his/her code has a single responsibility.

Sorry to get on my soapbox, but I've seen this "lesson" make ugly code even uglier when programmers don't understand the why behind the lesson.
